A vehicle rear lift platform 100 according to an embodiment of the present invention is described below with reference to fig. 1-4.

The vehicle rear lift platform 100 according to an embodiment of the present invention may include: a platform body 1 and an auxiliary rolling mechanism 3.

As shown in fig. 1 to 4, a power battery in an electric vehicle is generally installed at a chassis position, and in order to facilitate a battery replacement operation of a battery replacement device in a battery replacement station, during the battery replacement process, a vehicle needs to be lifted and position-adjusted first, so that the power battery can be directly opposite to a battery replacement trolley. Therefore, a vehicle lifting platform is arranged in the battery replacement station and used for lifting and adjusting the position of the vehicle.

Wherein, vehicle lift platform includes: a vehicle front lift platform 200 and a vehicle rear lift platform 100. The front vehicle lifting platform 200 is adapted to cooperate with the rear vehicle lifting platform 100 to position and lift the front and rear wheels of the vehicle so that the battery changing cart positioned between the front vehicle lifting platform 200 and the rear vehicle lifting platform 100 can change the power battery at the bottom of the lifted vehicle.

Further, the vehicle rear lifting platform 100 can adjust the transverse position of the vehicle rear wheel so as to realize transverse centering adjustment of the wheel, and the vehicle front lifting platform 200 is matched with the transverse centering of the vehicle front wheel and the adjusting effect of the longitudinal wheel axle distance so as to realize integral centering adjustment of the vehicle so as to ensure transverse centering of the vehicle, so that the power battery on the vehicle is opposite to the battery replacing trolley so as to facilitate replacement of the power battery by the battery replacing trolley. Wherein, the platform body 1 is provided with a flat straightening roller mechanism 2 to avoid sliding friction between the rear wheels of the vehicle and the platform body 1 in the process of transversely centering and clamping the vehicle by the lifting platform 100 behind the vehicle.

Because the traditional vehicle rear lifting platform can not ensure that the rear wheel of the vehicle and the contact part of the rear wheel of the vehicle are completely and accurately positioned on the flat straightening roller mechanism for vehicles of different vehicle types, the frame formed by welding the rectangular pipes and positioned around the flat straightening roller mechanism can generate sliding friction with the tires of the vehicle, and therefore, the transverse positioning of the vehicle is difficult, and the tires of the vehicle can be worn.

To this end, the embodiment of the present invention designs a vehicle rear lifting platform 100 having an auxiliary rolling mechanism 3 at a front side edge of the flat leveling roller mechanism 2 facing the vehicle front lifting platform 200 and/or a rear side edge away from the vehicle front lifting platform 200. Therefore, sliding friction generated between the part of the rear wheel of the vehicle, which falls outside the flat straightening roller mechanism 2, and the lifting platform 100 behind the vehicle can be converted into rolling friction, so that the abrasion of the tires of the vehicle is avoided, and the generation of noise is also avoided. The auxiliary rolling mechanism 3 is movably arranged on the platform body 1 so as to achieve the purpose of converting sliding friction into rolling friction.

Further, the auxiliary rolling mechanism 3 is located at a front side edge of the flat correcting roller mechanism 2 facing the vehicle front lifting platform 200 and/or a rear side edge of the flat correcting roller mechanism 2 away from the vehicle front lifting platform 200. The auxiliary rolling mechanism 3 located at the front side edge of the flat correcting roller mechanism 2 facing the vehicle front lifting platform 200 can assist the vehicle to adjust the transverse position through the cooperation between the vehicle tires in contact with the front edge of the flat correcting roller mechanism 2, and the sliding friction between the vehicle tires and the vehicle rear lifting platform 100 is converted into rolling friction, so that the friction force between the vehicle tires and the vehicle rear lifting platform 100 is greatly reduced, the positioning process is more labor-saving, the vehicle tires are prevented from being worn, and the noise is also avoided.

In the same way, the auxiliary rolling mechanism 3 at the rear side edge of the lifting platform 200 before the vehicle, which is far away from the flat correcting roller mechanism 2, can assist the vehicle to adjust the transverse position through the matching between the vehicle tires in contact with the rear edge of the flat correcting roller mechanism 2, and convert the sliding friction between the vehicle tires and the lifting platform 100 after the vehicle into the rolling friction, thereby greatly reducing the friction between the tires and the lifting platform 100 after the vehicle, not only making the positioning process more labor-saving, but also avoiding the abrasion of the vehicle tires, and also avoiding the generation of noise.

In other words, when the vehicle length is long, causing the vehicle tire to contact the front and rear edges of the leveling roller mechanism 2, the auxiliary rolling mechanism 3 may contact the vehicle tire of the protruding portion to assist the lateral positioning of the vehicle. That is to say, for vehicles of different vehicle models, the vehicle rear lifting platform 100 according to the embodiment of the present invention can be accurately positioned, and therefore, the vehicle rear lifting platform 100 according to the embodiment of the present invention has better versatility.

According to the vehicle rear lifting platform 100 provided by the embodiment of the utility model, the vehicle rear lifting platform 100 can avoid sliding friction with a vehicle tire, so that the friction force between the vehicle tire and the vehicle rear lifting platform 100 is greatly reduced, the positioning process is more convenient and labor-saving, the vehicle tire is prevented from being worn, vehicles of different vehicle types can be accurately positioned, and the vehicle rear lifting platform 100 has better universality.

According to further embodiments of the present invention, the auxiliary rolling mechanism 3 includes: a mounting bracket 31 and a plurality of auxiliary ball structures (not shown in the figure), which are rotatably disposed on the mounting bracket 31 to make the friction of the contact portion be rolling friction when the vehicle tire and the auxiliary roller structure 32 are relatively moved, thereby reducing the friction between the vehicle tire and the vehicle rear lifting platform 100 to facilitate the lateral positioning of the vehicle.

With reference to the embodiment shown in fig. 1 to 3, the rotatable direction of the auxiliary roller structure 32 is the same as the rotatable direction of the roller structure in the leveling roller mechanism 2, so that the auxiliary roller structure 32 and the roller structure can rotate in the same direction in the process of vehicle transverse positioning, and interference between the auxiliary roller structure 32 and the roller structure is avoided in the process of vehicle transverse movement, which hinders the movement of the vehicle, thereby improving the positioning accuracy and making the positioning process more labor-saving.

Referring to fig. 2 and 3, the extension direction of the supplementary drum structure 32 is the same as the extension direction of the drum structure. Wherein, the auxiliary roller structure 32 and the roller structure extend along the length direction of the vehicle. Therefore, the arrangement is more convenient, the rotating direction of the auxiliary roller structure 32 and the rotating direction of the roller structure can be ensured to be the transverse direction along the vehicle, so that the transverse positioning of the vehicle is facilitated, the difference between the rotating direction of the auxiliary roller structure 32 and the rotating direction of the roller structure in the transverse positioning process of the vehicle is avoided, and the auxiliary effect of the auxiliary roller structure 32 on the transverse positioning of the vehicle is better.

As shown in fig. 4, the plurality of auxiliary roller structures 32 are arranged at equal intervals and flush, so that the stress between the auxiliary roller structures 32 in the contact part with the vehicle tire is more balanced, the overall stability of the auxiliary roller structures 32 is better, and the auxiliary effect of the auxiliary roller structures 32 on the transverse positioning of the vehicle is better.

As shown in fig. 1 to 3, the upper surface of the auxiliary roller structure 32 is flush with the upper surface of the roller structure to avoid a height difference between the upper surface of the auxiliary roller structure 32 and the upper surface of the roller structure, so that the vehicle can be placed on the vehicle lifting platform more stably, and the vehicle can be moved more stably in a lateral direction.

Referring to fig. 1-3, the diameter of the auxiliary roller structure 32 is smaller than the diameter of the roller structure, and the axial length of the auxiliary roller structure 32 is smaller than the axial length of the roller structure. Thereby, it is more convenient to dispose the auxiliary roller structure 32 on the vehicle rear lifting platform 100 to ensure the disposition stability of the auxiliary roller structure 32 on the vehicle rear lifting platform 100.

As a preferred embodiment, the ratio of the diameter of the auxiliary roller structure 32 to the diameter of the roller structure is a, 3/10 ≦ a ≦ 3/8. I.e. the ratio between the diameter of the auxiliary roller structure 32 and the diameter of the roller structure is defined between 3/10 and 3/8. Thereby, it is more convenient to dispose the auxiliary roller structure 32 on the vehicle rear lifting platform 100 to ensure the disposition stability of the auxiliary roller structure 32 on the vehicle rear lifting platform 100.

As shown in fig. 4, the mounting bracket 31 is configured as a "U" shaped bracket, and the mounting bracket 31 includes: an L-shaped plate 311 and a vertical plate 312, wherein the vertical plate 312 is fixedly connected with the L-shaped plate 311 so as to facilitate the installation of the auxiliary roller structure 32. A rotating shaft 313 is connected between the vertical plate 312 and the L-shaped plate 311, and the auxiliary roller structure 32 is rotatably sleeved on the rotating shaft 313, so that the auxiliary roller structure 32 can be rotatably arranged on the mounting bracket 31, thereby realizing rolling friction with a vehicle tire.
