Description

Technical Field

[0001] This application belongs to the field of battery swapping technology, and particularly relates to an adaptive battery swapping device. Background Art

[0002] The replacement of fuel vehicles by new energy vehicles has become a development trend. Heavy trucks consume a large proportion of fuel and cause relatively heavy environmental pollution. Therefore, new energy heavy trucks have become an important part of solving environmental pollution problems. However, due to reasons such as the long charging time of new energy heavy trucks and the occupation of more public resources during charging, the battery swapping and energy replenishment method of separating the vehicle and the battery has been favored and pursued by more and more heavy truck users.

[0003] When a pure electric heavy truck is swapping batteries, since the components of the battery swapping device adopt a cantilever beam structure, due to the deflection deformation and assembly clearance caused by the load-bearing of the cantilever beam assembly itself, during the battery swapping process, the heavy truck battery box will tilt forward. As a result, during the lifting process of the battery box, the battery pack and the guiding components on the vehicle are unevenly stressed, causing additional wear, affecting the battery swapping life of the battery box, and also causing the battery box to be easily stuck in the guiding components during the lifting process of battery swapping, thus affecting the battery swapping success rate. Summary of the Utility Model

[0004] The purpose of the embodiments of this application is to provide an adaptive battery swapping device, which can solve the problems of battery swapping failures and wear caused by deformation during the operation of the existing battery swapping device.

[0005] To solve the above technical problems, this application is implemented as follows:

[0006] In a first aspect, the embodiments of this application provide an adaptive battery swapping device, which is applied to a cantilever beam. The cantilever beam extends along a first direction. The adaptive battery swapping device includes an adaptive device and a lifting device. The adaptive device is connected to the cantilever beam, and the lifting device is connected to the side of the adaptive device away from the cantilever beam. The adaptive device includes a first substrate and a rotating assembly. The first substrate is connected to the cantilever beam, and the rotating assembly is connected to the first substrate and the lifting device. The lifting device includes a first end and a second end opposite to each other along the first direction. The rotating assembly includes a rotating shaft and a movable member. The movable member is movably connected to the rotating shaft. The rotating shaft extends along a second direction. The movable member can rotate around the rotating shaft. The movable member is connected to the first substrate and the lifting device, and thus drives the first end and the second end to move upward or downward along a third direction respectively. Among them, the first direction, the second direction, and the third direction are perpendicular to each other in pairs.

[0007] In the embodiment of the present application, the adaptive device is cooperatively connected with the cantilever beam for implementing battery swapping of a vehicle.

[0023] The adaptive power exchange device provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0024] See Figures 1 to 2, embodiments of the present application provide an adaptive battery swapping device, which is applied to a cantilever beam 1 that extends along a first direction X. The adaptive battery swapping device includes an adaptive device 2 and a sling device 3. The adaptive device 2 is connected to the cantilever beam 1, and the sling device 3 is connected to a side of the adaptive device 2 away from the cantilever beam 1. The adaptive device 2 includes a first substrate 21 and a rotating assembly 20. The first substrate 21 is connected to the cantilever beam 1, and the rotating assembly 20 is connected to the first substrate 21 and the sling device 3. The sling device 3 includes a first end 30 and a second end 31 that are opposite to each other along the first direction X. The rotating assembly 20 includes a rotating shaft 201 and a movable member 202. The movable member 202 is movably connected to the rotating shaft 201. The rotating shaft 201 extends along a second direction Y. The movable member 202 can rotate around the rotating shaft 201. The movable member 202 is connected to the first substrate 21 and the sling device 3, and thus drives the first end 30 and the second end 31 to move upward or downward along a third direction Z respectively. Among them, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other in pairs.

[0025] In the embodiments of the present application, the adaptive device 2 and the cantilever beam 1 are cooperatively connected to realize battery swapping for a vehicle. In practical applications, the cantilever beam 1 drives the adaptive battery swapping device to move. The adaptive battery swapping device can hoist a battery box. At the same time, the adaptive battery swapping device can horizontally adjust the sling device 3 in the case of deflection deformation of the cantilever beam 1, so as to keep the horizontal position of the battery box. Specifically, the adaptive device 2 includes a first substrate 21 and a rotating assembly 20. The first substrate 21 is provided to realize the connection between the adaptive device 2 and the cantilever beam 1. The rotating assembly 20 is connected between the first substrate 21 and the sling device 3. The rotating assembly 20 includes a rotating shaft 201 and a movable member 202. The rotating shaft 201 can extend along the second direction Y. The movable member 202 can rotate around the rotating shaft 201. One end of the movable member 202 is connected to the first substrate 21, and the other end is connected to the sling device 3. It can be understood that when the movable member 202 rotates around the rotating shaft 201, the sling can move with the rotation of the movable member 202. Further, the sling includes a first end 30 and a second end 31 that are oppositely arranged along the first direction X. In practical applications, when the sling device 3 hoists the battery box, the cantilever beam 1 may have deflection deformation. At this time, the movable member 202 will rotate around the rotating shaft 201. When the movable member 202 rotates, the first end 30 can move upward along the third direction Z. Correspondingly, the second end 31 can move downward along the third direction Z. Or, the first end 30 can move downward along the third direction Z. Correspondingly, the second end 31 can move upward along the third direction Z. The upward or downward movement of the above-mentioned first end 30 and second end 31 can improve the inclination influence of the cantilever beam 1 on the sling device 3 due to deflection deformation, and further improve the inclination influence on the battery box, avoiding uneven force between the battery box and the guiding assembly on the vehicle, and having the beneficial effect of avoiding the battery box being easily stuck during the battery swapping and lifting process.

[0026] Optionally, in the embodiment of the present application, the adaptive device 2 further includes a telescopic assembly 22. One end of the telescopic assembly 22 is fixedly connected to the first substrate 21, and the other end of the telescopic assembly 22 is fixedly connected to the first end 30 and the second end 31. The telescopic assembly 22 can extend or contract along the third direction Z.

[0027] In the embodiment of the present application, the telescopic assembly 22 is provided to improve the smoothness of the movement of the lifting device 3. The telescopic assembly 22 can extend or contract along the third direction Z. One end of the telescopic assembly 22 is fixedly connected to the first substrate 21, and the other end is fixedly connected to the first end 30 and the second end 31. In practical applications, the movable member 202 rotates around the rotating shaft 201, which can realize the upward movement of the first end 30 and the downward movement of the second end 31, or the downward movement of the first end 30 and the upward movement of the second end 31. The telescopic assembly 22 can shorten as the first end 30 or the second end 31 moves upward, and can extend as the first end 30 or the second end 31 moves downward. When the first end 30 and the second end 31 move upward or downward along the third direction Z respectively, the telescopic assembly 22 always has a certain traction force on the first substrate 21 and the lifting device 3. The setting of the telescopic assembly 22 has the beneficial effect of improving the smoothness of the movement of the first end 30 and the second end 31.

Specifically, both the first movable part and the second movable part are movably connected to the rotating shaft 201, and the rotating shaft 201 extends along the second direction Y. It can be understood that both the first movable part and the second movable part can rotate around the rotating shaft 201. Further, one end of the first movable part away from the rotating shaft 201 is connected to the first substrate 21, and one end of the second movable part away from the rotating shaft 201 is connected to the lifting tooling. In practical applications, when the first movable part and the second movable part rotate relative to each other around the rotating shaft 201, the first substrate 21 and the lifting tooling also rotate relative to each other. And the first substrate 21 is fixedly connected to the cantilever beam 1. It can be understood that when the lifting device 3 lifts the battery box, the cantilever beam 1 may have deflection deformation and the battery box may be tilted. At this time, the relative rotation occurs between the first substrate 21 and the lifting device 3, which can improve the tilt of the battery box and avoid the uneven force between the tilted battery box and the guiding assembly on the vehicle, having the beneficial effect of avoiding the easy jamming of the battery box during the battery box replacement and lifting process.

[0034] In the embodiment of the present application, the four telescopic members 221 are arranged in an array along the first direction X and the second direction Y. It can be understood that the four telescopic members 221 can form a form of a four-corner array arrangement, and two telescopic members 221 are provided at both the first end 30 and the second end 31. In practical applications, the first end 30 moves upward along the third direction Z. Correspondingly, the second end 31 moves downward along the third direction Z, or the first end 30 moves downward along the third direction Z. Correspondingly, the second end 31 moves upward along the third direction Z.
