Definitions
- the present invention relates to a brake warning device comprising a braking detector and a lighting device fitted to said vehicles and in particular those which can be dismantled or sold as retrofit or after-sales.
- the invention also relates to a vehicle equipped with said brake warning device.
- Another brake warning system consists of equipping lighting with an accelerometer. But braking detection can only be done with a delay and often incorrectly due to movements generated by the vehicle.
- the invention offers a solution to the problems mentioned above, by allowing a brake warning without adjustments and easy to mount as retrofit, while guaranteeing improved detection.
- a first aspect of the invention relates to a braking warning device for a manual brake of a vehicle V with at least two wheels comprising a handlebar equipped with manual brakes, a lighting device and a communicating braking detector with the wireless transmission lighting device, it is characterized in that the braking sensor comprises a force sensor and is disposed in a sleeve including a battery.
- the force sensor is a compact and low-consumption device which allows it to detect when the user brakes simply by directly measuring the force he exerts on the brake lever, no mechanical element is necessary which facilitates mounting in especially in post equipment.
- the lighting device is for example a brake light.
- the battery may be a rechargeable battery or not, for example a battery that can be changed.
- the force sensor is placed on a ductile support. It can for example be metallic. The support allows you to hold the force sensor.
- At least one of the hollow cylindrical parts comprise interior grooves.
- grooves are provided inside the hollow cylindrical parts of the sleeve in order to reduce the contact surface. These grooves are limited to a quarter to a third of the surface in order to maintain sufficient grip and they are diametrically opposed to the force sensor.
- the sleeve comprises at least one light source constituting an ignition indicator of the lighting device.
- This indicator allows the user to see if their rear light is on or not.
- the sleeve includes an opening or a transparent area so that the indicator is visible.
- the ignition indicator alerts when the rechargeable battery is discharged.
- discharged we mean a battery with a charge rate of less than 30% for example.
- the user is informed when the battery is discharged, which prevents him from driving with an ineffective braking detector.
- the wireless transmission comprises a radio transceiver.
- the lighting device is thus controlled remotely.
- Wireless transmission is achieved using the radio transceiver.
- the light intensity emitted by the lighting device increases with the force applied to the force sensor.
- the following vehicle can thus know whether the braking is strong or not and adapt its driving accordingly.
- the lighting device only turns on when the pressure on the force sensor is greater than 600g, or even 800g.
- the force sensor is arranged on the brake lever on the side opposite the handle.
- the brake sensor is mounted on the handle so that the force sensor is located on the side where the user's fingers press, that is to say towards the handle.
- FIG. 1 shows a handle with a braking detector according to the invention
- FIG. 2 is an exploded view of the braking detector according to the invention.
- FIG. 5 is an exterior perspective view of the brake warning device with the brake detector seen from the connector side and the lighting device,
- FIG. 6 shows a cyclist equipped with a brake warning device according to the invention.
- the braking detector 2 is installed on the brake lever 12 and is substantially parallel to it.
- the braking detector 2 comprises a sleeve 20, a support 23, a force sensor 22, a housing 24. It further comprises a printed circuit 25, for example a plate of rigid insulating material such as an epoxy resin, on which is placed a control module 251 configured to control the braking detector 2.
- the lighting device 14 or 15 here comprises a wireless transceiver (not shown) which communicates with a wireless transceiver of the braking detector 2.
- the transceiver of the braking detector 2 is composed advantageously of a radio module included in a control module 251 and of a antenna 26 integrated into the printed circuit 25.
- the transceiver can also be composed of an antenna 26 and a radio module separate from the control module 251.
- transceivers makes it possible to ensure wireless transmission in both directions of communication to carry out pairing between the braking detector 2 and the lighting device 14, 15 and also to communicate with the detector braking 2 the operating state of the lighting device 14 or 15.
- the braking detector 2 can be connected to several lighting devices 14, 15 or several braking detectors 2 can be connected to one or more braking devices lighting 14, 15. In this case, it is a multipoint communication protocol.
- the wireless transmission is carried out in only one direction.
- the braking detector 2 then comprises a transmitter and the lighting device 14, 15 comprises a receiver.
- the braking detector 2 controls the lighting device 14, 15 without feedback and cannot pair with it by means of wireless communication.
- the sleeve 20 has an elongated shape in the same direction as the brake lever 12. It is flexible and deformable, composed of a material having elastic properties such as an elastomer, for example silicone, rubber, made of TPU, and is slipped onto the brake lever 12 thanks to three cylindrical hollow parts 200 placed from a first end 20a, along the sleeve 20, thus making it easily removable.
- each hollow cylindrical part 200 serves as a means of fixing the braking detector 2 on the brake lever 12, like a clamp for example.
- the section of the hollow cylindrical part 200 is smaller than the section of the brake lever 12 so as to ensure sufficient tightening and support. There could be only one, two or more than three without departing from the scope of the present invention.
- the advantage of having at least two hollow cylindrical parts 200 is to distribute the holding force on the brake lever 12 along the sleeve 20 and to have at least one gripping zone 201 located between them to remove the sleeve 20 easily.
- These cylindrical hollow parts 200 advantageously comprise interior grooves 2000 (see Figure 4). These are oriented in the longitudinal direction of the sleeve 20 so as to facilitate the sliding of the sleeve 20 on the brake lever 12 both during assembly and during disassembly of the braking detector 2. These grooves 2000 are advantageously present on only a portion of the interior surface of the hollow cylindrical parts 200 so as to maintain sufficient adhesion with the surface of the brake lever 12, for example a quarter to a third of the interior surface. They are preferably placed on the side opposite the force sensor 22.
- the area devoid of grooves 2000 ensures better adhesion in the area in contact with the surface of the brake lever 12 located on the side opposite the handle 11 while the area of the brake lever 12 on the side of the handle 11 is often hollow.
- the material of the hollow cylindrical parts 200 being flexible, preferably made of elastic material, it makes it possible to adjust to different sizes and shapes of brake levers 12.
- the area without groove is removed from the surface of the lever. brake lever 12 by means of the gripping zone 201, to keep only the zone comprising grooves 2000 in contact with the brake lever 12.
- each hollow cylindrical part 200 can be separated into two elements in order to laterally fix the sleeve 20 on the brake lever 12 without needing to thread it in the longitudinal direction.
- it can be composed of two straps adjustable according to the size of the brake lever 12 and connected together by means of loops and hooks or of a strap passing through a trigger guard directly connected to the sleeve 20 or by means of a strap with holes into which a lug fixed on the sleeve 20 is inserted.
- the sleeve 20 constitutes the external envelope of the braking detector 2. It is hollow over its entire length to insert the support 23, the force sensor 22 and the housing 24 comprising the printed circuit 25 and a rechargeable battery 21 .
- the force sensor 22 is fixed on the support 23 by gluing or by means of double-sided adhesive or adhesive tape surrounding the assembly. It is located at the first end 20a of the sleeve 20 facing the hollow cylindrical parts 200 placed near the first end 20a to be in contact with the fingers of the user U when he brakes.
- the portion of the sleeve 20 located on the side of the end 20a includes only the force sensor 22 and the support 23, which makes this portion less thick to be easily accessible by the fingers of the user U.
- the force sensor 22 is located on the support 23 on the side opposite the cylindrical hollow parts 200 in order to be closest to the user's fingers U.
- the battery can be non-rechargeable, without departing from the scope of the present invention, this will for example be a battery that can be changed if it is discharged.
- the battery 21 has a substantially parallelepiped and flat shape. It is attached to the printed circuit 25 in order to reduce the bulk of the box 24.
- the housing 24 is advantageously arranged at a second end 20b of the sleeve 20 offset relative to the three hollow cylindrical parts 200 to be positioned on the portion of the brake lever 12 closest to the base 18 of the manual brake, in the area which is not in contact with the user's fingers U.
- the force sensor 22 is connected to the printed circuit 25.
- the support 23 extends beyond the force sensor 22 to the second end 20b of the sleeve 20 to attach to the housing 24 by nesting.
- the support 23 can be blocked in translation by deformation of small tabs 232 which serve as stops, once the support 23 inserted into the housing 24 through the slot 242.
- the support 23 is blocked in translation by one or more screws fixed on the box 24.
- the housing 24 comprises the rechargeable battery 21, the printed circuit 25, the antenna 26 and a light source 27 which can be an opto-electronic element, for example a light-emitting diode, located on the printed circuit 25.
- the braking detector 2 may not contain a light source 27 without departing from the scope of the present invention.
- the housing 24 does not have any protrusion 240 facing the side openings 203.
- the housing 24 is in the form of a box open on one side and closed on the other sides and having several openings: a first side 24a comprises a first opening 241 for accessing the connector 210 and a slot 242 for there slide the support 23, a second side 24b opposite the first side 24a comprises a second opening 243 to connect the force sensor 22 to the printed circuit 25 and slide the support 23 there, a third side 24c with a third opening 244 to place there the push button 250.
- the support 23 can also be a metal rod comprising a smaller section in the weak zone 230.
- the sleeve 20 being flexible, the braking detector 2 thus bends at the level of the weak zone 230 and maintains this deformation thanks to the support 23, which makes it possible to adapt its shape to the curvature and shape of the brake lever 12 as illustrated in Figure 1.
- the support 23 can be replaced by another type of rigid support with, for example, an articulation in place of the weak zone 230.
- the braking detector 2 To mount the braking detector 2, it is necessary to slide the sleeve 20 onto one of the brake levers 12 of vehicle V, preferably onto the lever controlling the rear brake, but it is possible to install two braking detectors 2 : one per brake lever. It is then necessary to fix the lighting device 14, 15 on the vehicle V or on the helmet 16 of the user. Pairing is also necessary between the transceiver of the braking detector 2 and the transceiver of the lighting device 14, 15. It is carried out by pressing the push button 250 and a button 17 placed on the device lighting 14, 15. If more than two braking detectors and/or lighting devices communicate, the transceivers must be paired two by two successively.
- the braking detector 2 must be positioned so that the part of the sleeve 20 comprising the force sensor 22 is positioned at the end of the brake lever 12 facing the fingers of the user U when he it brakes by pressing the brake lever 12.
- the force sensor 22 is thus arranged on the brake lever 12 on the side opposite the handle 1 1 so as to cover the surface of the brake lever 12 in contact with the fingers of the user U.
- the housing 24 is preferably positioned on the brake lever 12 in the area located on the side of the base 18 of the manual brake, which in this way does not hinder the movement of the brake lever 12 during braking .
- the portion of the sleeve 20 where the force sensor 22 is located is thinner than the portion of the sleeve 20 where the housing 24 is located in order to minimize the thickness of the brake lever 20 in the area in contact with the fingers.
- the more the user brakes the more he presses on the force sensor 22, the more the light emitted by the lighting device 14, 15 increases.
- the light source 27 placed in the sleeve 20 lights up at the same time as the lighting device 14, 15 thus informing the user U of the ignition of the latter, constituting an indicator of the ignition of the fire stop.
- the transceiver of the lighting device 14, 15 must send the information back to the transceiver of the braking detector 2.
- the braking detector 2 is not removable. It remains permanently on the brake lever. It can be fixed by screwing, by clipping or directly integrated into the brake lever 12.
- the braking detector 2 can be equipped with additional functions such as flashing or non-flashing lighting, an audible warning or a geolocation tracker. It can also be provided with one or more buttons capable of activating functions other than braking detection, such as indicators advantageously included on the lighting device 14, 15.
