Specific embodiment

The utility model is described in further detail below in conjunction with figure embodiment.

Referring to Fig. 1, the schematic diagram of power assist vehicle applied by the container structure of the utility model, including front truck is 1, preceding crossbeam 2, rear crossbeam 3, seat 4 and wheel, wherein rear crossbeam 3 is arranged in the front end that preceding crossbeam 2 is arranged in 1 in front truck, seat 4 Top, can be folded against between preceding crossbeam 2 and rear crossbeam 3, wheel include be arranged in preceding 2 bottom end of crossbeam driving wheel 51 and Two driven wheels 52 of rear 3 rear side of crossbeam are set.

Referring to figs. 2 and 3, seat 4 includes the chair back 41, seat station 42 and elevating mechanism 43, and elevating mechanism 43 makes seat Platform 42 can crossbeam 3 makees elevating movement afterwards relatively.The chair back 41 is fixedly connected with seat station 42, synchronization lifting.

Referring to 3~Fig. 5, elevating mechanism 43 includes the guide rail 431 longitudinally extended, the sliding rail 432 being arranged in the chair back 41, drives Motivation structure 433 and transmission mechanism 434.Wherein, the chair back 41 includes the first chair back shell 411 and second chair back made of two fastenings Shell 412, above-mentioned sliding rail 432 and driving mechanism 433 be arranged at the first chair back shell 411 and the second chair back shell 412 it Between space in.Connecting column 413 can be respectively set in two sides in first chair back shell 411 and the second chair back shell 412, thus The two sides of sliding rail 432 can be fixed with connecting column 413 respectively, so that sliding rail 432 is connected and fixed with the chair back 41.On guide rail 431, position Tourelle 44 is provided with below sliding rail 432, for after the folding of power assist vehicle vehicle, tourelle 44 to pass through and is arranged thereon Idler wheel and ground face contact, and can be rolled on bottom surface, to reduce the power for pulling power assist vehicle.

Driving mechanism 433 uses motor 4331, and is dual-output motor, and two output shafts of motor 4331 pass through gear-box Transmission mechanism is connected to after 4332 decelerations.Transmission mechanism includes two screw rods extended in the longitudinal direction 4341, respectively with gear-box 4332 one of output end connection, screw rod 4341 are passed through out of sliding rail 432.Silk braid is provided on each screw rod 4341 4342, silk braid 4342 is connected and fixed with sliding rail 432, can such as be fixed with the mode of clamping, grafting.

Guide rail 431 have spaced apart two, guide rail 431 from the inside of the chair back 41 extend downwardly up to rear crossbeam 3 On component rotation connection.The side of each guide rail 431 towards sliding rail 432 is formed with sliding slot 4311, and sliding slot 4311 is to far from sliding The direction of rail 432 is recessed.It is provided with sliding block 4321 on sliding rail 432, for cooperating with sliding slot 4311, is slidably disposed on In sliding slot 4311 so that sliding rail 432 can opposite rail 431 sliding and make elevating movement.By arranging two 431 Hes of guide rail Two sets of transmission mechanism 434 can make the elevating movement even running of the chair back 41, avoid injustice caused by single 4341 stress of screw rod Surely, unstability manual, hydraulic, pneumatic in the past is solved.

One of guide rail 431 is separately provided for the microswitch 435 of limit close to the position of top and bottom, sliding Baffle 4322 is provided on rail 432, microswitch 435 can be electrically connected with motor 4331, control motor 4331 with output signal Operation.When sliding rail 432 is run to upward or downward so that baffle 4322 is pressed into corresponding position microswitch 435, then table Show that seat 4 has been elevated to extreme position, it is out of service that driving mechanism 433 can be automatically controlled.

Nylon sheath wire 4312 is provided in sliding slot 4311, so that the sliding block 4321 of sliding rail 432 and nylon sheath wire 4312 slide Cooperation, so as to reduce noise when operation, and can increase lubrication.

When it is required that seat 4 rises (or decline), start driving mechanism 433, so that screw rod 4341 rotates, from And silk braid 4342 on screw rod 4341 rises (or decline), thus sliding rail 432 rises (or decline) with silk braid 4342, and final So that the chair back 41 is synchronous with seat station 42 to rise (or decline), it, can when seat station 42 rises (or fall) to required high speed Out of service by the switch control driving mechanism 433 on remote controler or power assist vehicle, seat 4 rises (or fall) to position.Certainly, Can also without manually controlling, until the baffle 4322 on sliding rail 432 is when being pressed into the microswitch 435 of upper end (lower end), It is out of service to automatically control driving mechanism 433.
