Definitions

  • This patent application for invention refers to an audible and visual alarm system for pneumatic, hydraulic and electric parking brakes for motor vehicles in general, which aims to solve and avoid problems inherent and recurring to the involuntary movement of motor vehicles, such as trucks, buses and similar, due to forgetting to activate the parking brake.
  • the present invention aims to provide a system that emits sound and visual signals to remind the driver not to activate the parking brake, in trucks, buses, machines, medium and small vehicles.
  • the present invention has its field of application focused on the automotive industry, specifically in trucks, buses and medium and small vehicles, and can also be applied to heavy machinery such as (tractors, cranes, forklifts, etc.), aiming to increase safety and prevent accidents caused by forgetting not to activate the parking brake.
  • Forgetting to apply the parking brake can be attributed to a variety of factors, such as driver distraction, stress, or simply a lack of knowledge of best safety practices. Regardless of the cause, the result can be devastating, leading to serious injuries, property damage, and in extreme cases, even fatalities.
  • the previous feature is an emergency parking brake system that is only activated if the vehicle is on, and is specific to articulated vehicles, and is activated from inside the cabin, in addition to parking trailers and tractor units together and simultaneously.
  • the present invention relates to a system that increases safety in vehicles such as trucks, buses, tractors, cranes, forklifts, etc. and small and medium-sized cars, by reminding the driver to apply the parking brake whenever necessary, regardless of the whether the vehicle is on or off.
  • the system of the present invention uses an electronic control unit composed of a pressure sensor, occupancy sensors, and an audible and visual device, which, when incorporated into the vehicle's parking brake system, is activated when the driver does not apply the parking brake, reminding the driver to apply said parking brake.
  • the system of the present invention is composed of an electronic control unit with an audible device to emit alerts and a pressure sensor to monitor the air and/or fluid pressure in the vehicle's parking brake, and in light vehicles they are activated mechanically, that is, the manual brake lever.
  • the electronic control unit has a quick coupling to connect to the vehicle's pneumatic system, being electrically powered by the vehicle's 12/24V system.
  • the system controls the activation of the audible and visual device, activating them if the parking brake is deactivated.
  • the electronic control unit can be synchronized with the electrical part of the pneumatic actuator of a bus door, for example, being connected to occupancy sensors incorporated into the seat of a bus, activating the alert devices only in the absence of pressure exerted on the driver's seat.
  • V Compatibility with pneumatic, hydraulic and mechanical stationary brakes, allowing their application in trucks, buses, machines such as (tractors, cranes, etc.) and medium and small vehicles;

  • THE AUDIBLE AND VISUAL ALARM SYSTEM FOR PNEUMATIC, HYDRAULIC AND/OR ELECTRIC PARKING BRAKE OF MOTOR VEHICLES consists of a system (1) that can be implemented in the pneumatic, hydraulic or electric parking brake of a truck, bus, tractor, crane, forklift, etc. and can also be implemented in a mechanical parking brake of a medium or small vehicle.
  • the system (1) is basically formed by an electronic control unit (2) equipped with a pressure sensor (4), an audible device (3) and a visual device (10), so that the electronic control unit (2) manages and processes the signals from said pressure sensor (4), as well as from an audible device (3) and the visual device (10), aiming to increase vehicle safety, reminding the driver to activate the parking brake when necessary.
  • the sound device (3) of the electronic control unit (2) may be a siren, horn and the like, to emit a warning sound when necessary.
  • the pressure sensor (4) of the electronic control unit (2) is used to monitor the air pressure in the vehicle's pneumatic parking brake system.
  • the electronic control unit (2) also consists of a quick coupling (5), which allows air to enter the pressure sensor (4), whose quick coupling (5) is connected to the pneumatic parking brake system of a truck or bus through a pneumatic connection (6A) coming from a T-connection hose (6).
  • the pressure sensor (4) of the electronic control unit (2) is connected to the electrical part (7) of the truck, bus, etc. door directly to the 12/24v current without going through the ignition key, which is activated if there is pressure in the system and energizes the electronic control unit (2), and that of the truck door, by through a negative conductor (8), whereas, if the lever valve is activated, (no pressure in the system) that is, (parking brake activated), and the truck door is closed or open, the audible device (3) and the visual device (10) of the electronic control unit (2) are not activated.
  • the electronic control unit (2) of the system (1) in the present invention, has a relay (R) for signal inversion, which receives power from a positive conductor (7), which also powers the electronic control unit (2). Furthermore, a trigger and return point (P) is connected to the relay (R) and to the occupancy sensors (11) inserted in an occupancy cover (C), which, in turn, is covered in the seat (A) of a bus.
  • the occupancy sensors (11) detect the pressure exerted on the seat (A), in the presence of the driver, so that, when the occupancy sensors identify pressure exerted on the seat (A), in the presence of the driver, both the audible device (3) and the visual device (10) are not activated.
  • the occupancy sensors (11) do not detect pressure exerted on the seat (A), due to the absence of the driver, they immediately activate the audible device (3) and the visual device (10) to remind the driver to apply the parking brake.
  • the system (1) of the present invention can also be implemented in mechanical parking brakes of medium and small vehicles, through an activation key (13), which is connected to the electronic control unit (2), with the negative conductor (8) connected to the electrical part of the vehicle door, without passing through the system key.
  • the activation key (13) is fixed below the conventional parking brake lever. In this way, when the driver does not activate the parking brake and opens the vehicle door, instantly, the activation key (13) is activated, to alert the driver that he must activate the vehicle's parking brake.
  • the system (1) can also be applied to hydraulic stationary brakes of tractor lines, cranes, forklifts, among others. Replacing the actuation point (13) of Fig. 3, with a hydraulic pressure sensor, which will be installed in the brake actuation valve of the machine in question, maintaining the operating mechanisms of the present invention.
  • the system (1) of the present invention has as its main objective to alert the driver when the vehicle's parking brake system is not activated, preventing accidents related to the vehicle moving without the driver, when he forgets to activate said parking brake.
  • the system (1) now proposed, aims to monitor the fluid or mechanical air pressure in the parking brake circuit of a truck, bus and/or light and heavy vehicles, as well as to identify the presence of the driver in the seat (A) of a bus, so that the driver is alerted by means of an audible device (3) and a visual device (10), to activate the parking brake of said vehicle. Therefore, the system (1), the object of the present invention, substantially increases the safety of the vehicle and its surroundings, since the system (1) will alert the driver to activate the parking brake whenever necessary.
