Definitions

  • the vehicles often are equipped with a wide variety of the vehicular affiliated tools such as the jack, tire air pump, trouble maker etc. for the drivers to conduct the repair and maintenance jobs themselves during the emergency situations whenever my common troubles like tire punctures take place, however the great number of these accessory tools often jam the luggage compartment occupying a large space in the car, besides the costs to buy them form a burden to the vehicle owners, therefore, the invention designs a compound tool with multiplification functions of the common motor-driven air pump and jack to improve the above-said defects.
  • the vehicular affiliated tools such as the jack, tire air pump, trouble maker etc.
  • the invention provides a jack having the air pump functions and using a common drive motor, so to use a common motor can reduce the costs required and the air pump and the jack are in integral structure with a smaller space and easy to carry for the users, the main feature of this design lies in that a single drive motor produces the multiplification functions to drive
  • the output shaft 102 of the drive motor 101 has a gear A for the selective coupling with the gear B to drive the air pump shaft 103 into motion or the gear C on the rotary shaft 104 of the oil hydraulic pump of the spiral jack or oil hydraulic jack, ie. to move the relationship position among the gears groups A, B, and C achieves the coupling between the gears A and B to drive the air pump in motion using forward and reverse rotation of the motor and the gears A and C coupled, whereas the motor is made to drive upward and downward the operating state of the jack as for the changes of the above said gear relationship, the lengthway displacement changes of the gear A can be in two states, ie.
  • an electro- magnetic clutch 105 or mechanical clutch 106 may be provided in the shaft of the gear B or C to achieve this purpose as shown in Fig. 1-3A and 1-3B; since the above said means are so common in the machinery structures that is known to the skilled men of arts, no detailed repetition on it is needed here.
  • the drive motor 210 has an enlongated shaft 201 which is used to drive the piston 203 of the air pump 202 and velocity reducing toothed wheel set 206 and 207 and also serves as the input shaft for the jack at the same time for driving velocity reducing toothed wheels 206' and 207' of jack oil pump.
  • the above-said structure is further provided with an operating device, so when it is used drive the oil pump 208 of the oil hydraulic jack, the elongated shaft 201 is used to drive the oil pump 208, in this design, a drain back flow operating valve 205 is provided in the fluid return circuit of the outlet of air pump 202 or jack 208, the drain valve of the unit to be operated can be set at the blocked position during the operation, while drain valves of the units not to be operated will be set at the respective drain position for the operating selections, thereby determining to drive the air pump or jack.
  • Fig. 2-1, 2-2 and 2-3 is an applicable example of the stand type jack, in which as shown in Fig. 2-1, a Land type jack main body 260 is installed vertically on the based seat 261; the main body is a cylinder type oil pressure tank coupled with a stand shaft 262 which can move upward and downward under the compression; a top block 263 is installed on the upper side of the stand shaft 262 and serves as carring working piece; a drive motor 210 with shaft 201 at its two ends is fixed transversely in the cylinder body, its end has a small toothed wheel 206 and a bias mechanism 204 (including bias curved shaft or bias link rod moved by bias wheel) coupled with large toothed wheel 207, thus it can transmit the force to crank 209 and then moves gas pump piston 203 to generate the gas pump function between the piston and gas pump; the gas pump has an intake opening for gas input, an exhaust opening for output of compressed gas and a gas channel connecting to a pressure manometer 264; then another output end shaft of the motor 210
  • Fig. 2-2 is a sectional diagram of Fig. 2-1;
  • Fig 2-3 is another sectional diagram of Fig. 2-1;
  • Fig. 2-4, 2-5 and 2-6 is an applicable example of this co-axial lain type jack, in which its structure is same as the traditional lain type jack, a wheel shaft 272 and wheel 273 are installed on the one side of the lain type machine body and a wheel 273 is installed on the other side for motion driving;
  • a drive rod 281 drived by an active oil pressure tank 280 is coupled with a risen arm set 274 using the coupling pin 276, the risen arm set 274 is coupled with two openings on the upper side of the machine body 271 using a set of penetrated rod 275 and it acts as the centre of the oscillation to accept the driving of the drive rod 281 on the active oil tank and then to move the upper arm 277 coupled with the other coupling pin 278 at its other end for the upward or downward motion of the supporting block 279; its main characters : a set
  • Fig. 2-7 the other example of the above said co-axial coupling way is shown in Fig. 2-7, in which the mechanical type clutch operating and controlling method conducts the operating selections on the air pump of spiral jack.
  • Fig. 2-7 its constructions is described as follows:
  • Fig. 2-7 shows its structure used for the drive of shear jack, its applicable example are shown in Fig. 2-8, 2-9 and 2-10, in which the based seat 280 is used for installation of 4 sets of supporting arms 281 on it; the lower parts of supporting set is coupled with the based seat using coupling pin 282, and its upper parts is also coupled with the supporting plate using a coupling pin 282; its two ends are coupled using screw hole pin 285 for the penetration of screw rod 216', the chute 289 on the guide rod is limited by the coupling pin 288 of penetrated hole 287 with the limited pin 286, thus the guide rod 216' is limited for its rotation; the relationship of the guide rod and coupling pin 288 with the penetrated hole 287 is the rotation in the original position, so that the screw hole pin 285 combinated screwedly by guide rod 216' is moved and let supporting arm 281 move upper supporting plate for upward and downward motion.
  • the above-said various compound structures can be further made into the AC/DC dual purpose type as shown in Fig. 4, its feature lies in that inside the base a transformer 401 is provided to transform the household power supply into a low voltage output, its low voltage output end is connected to a rectifier 402 forthe low voltage output, its output end can also be connected in parallel to the socked 403 on the above said DC input end to drive the above said DC motor 404 for driving the air pump or jack into motion, and this input socket 403 can make the DC output to act as a charger, or an output terminal is added to serve as a charger, thereby further making the invention become a tri-functional compound tool form, in this structure, a switch 405 is connected in series with the input end of the DC motor 404 to cut off the DC motor 404, when it serves as a charging power supply.
