Detailed Description
The technical scheme of the present invention is described in detail below, but the scope of the present invention is not limited to the embodiments.
In order to make the contents of the present invention more comprehensible, the present invention is further described with reference to fig. 1 to 3 and the detailed description below.
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
As shown in fig. 1, the support structure of the present embodiment includes a transmission portion provided behind the battery of the electric vehicle and below the seat 2 of the electric vehicle, and a support portion connected to the transmission portion.
As shown in fig. 1 and 2, the transmission part comprises a fixed bracket 3 vertically arranged on a storage battery mounting seat 1 of the electric vehicle, a stepping motor 4 is arranged on the fixed bracket, a motor shaft of the stepping motor is vertically downward, a screw rod 6 is arranged on the motor shaft of the stepping motor through a coupler 5, and the bottom end of the screw rod is arranged on the fixed bracket 3 through a bearing seat 7; the screw rod 6 is connected with the door-shaped supporting frame 8 through a screw thread pair, a flange nut 23 is arranged at the joint of the door-shaped supporting frame 8 and the screw rod 6, and the flange nut 23 is connected with the screw rod 6 through the screw thread pair. The door-type supporting frame is located in the fixed support, two supporting bottom ends 9 of the door-type supporting frame extend out of the fixed support, and a connecting rod 10 is arranged between the two supporting bottom ends.
As shown in fig. 1 and 2, the support portion includes two rear wheel support levers 11; the two rear wheel supporting levers are respectively arranged at the bottom ends of two supports in one-to-one correspondence, are symmetrically arranged about the rear wheel 13 of the electric vehicle, one ends of the two rear wheel supporting levers are respectively arranged at the bottom ends of the door-shaped supporting frame through movable hinges 14, the other ends of the two rear wheel supporting levers are respectively free ends and are respectively provided with rear universal wheels 15, rear lever protruding shafts 16 are respectively arranged on the two rear wheel supporting levers in a protruding mode, rear sliding blocks 17 are respectively arranged on the two rear lever protruding shafts through bearings, and the rear sliding blocks slide in rear sliding grooves 18; the rear chute is fixedly arranged on the electric vehicle rear wheel bracket 19. As shown in fig. 3.
The working process of the invention is as follows:
when the car is required to be parked, the stepping motor 4 rotates rightwards, the stepping motor 4 and the screw rod 6 are connected together by the coupler 5, so that the screw rod 6 rotates rightwards, the flange nut 23 moves upwards, the door-shaped supporting frame 8 moves upwards, and accordingly, the two rear wheel supporting levers 11 connected with the two supporting bottom ends 9 on the door-shaped supporting frame 8 are driven to move upwards, and the two rear sliding blocks 17 move horizontally in the rear sliding grooves 18 while the end parts of the two rear wheel supporting levers 11 move upwards; by applying the lever principle, the two rear universal wheels 15 at the free ends of the two rear wheel supporting levers move downwards while the ends of the two rear wheel supporting levers 11 move upwards; when the two rear universal wheels 15 are in contact with the bottom surface, the rear wheels of the electric vehicle rotate backwards, so that the whole electric vehicle moves backwards away from an original electric vehicle parking space, and the rear wheels of the electric vehicle completely leave the parking space, and at the moment, the rear wheels of the electric vehicle are supported by the two rear universal wheels 15; when the rear wheel of the electric vehicle is lifted upwards, the front wheel of the electric vehicle naturally supports downwards, and at the moment, the rear wheel 13 of the electric vehicle is supported by two rear universal wheels 15, and the front wheel of the electric vehicle is directly supported on the ground to finish parking.
Because the process of riding and the parking process are reverse processes, the stepping motor moves leftwards, and according to the transmission above, the two rear universal wheels are recovered upwards to complete the recovery of the supporting device; therefore, the present invention is not described in detail.
The supporting structure makes the universal wheel ascend and descend by using the lever principle; the lever principle further reduces the consumption of electric energy, and achieves the effects of energy conservation and emission reduction.
The invention is not related in part to the same as or can be practiced with the prior art.
As described above, although the present invention has been shown and described with reference to certain preferred embodiments, it is not to be construed as limiting the invention itself. Various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
