[0071] The utility model will be further illustrated by way of examples below, but the utility model is not limited in the scope of the examples.

[0072] Example 1

[0073] As Figures 1-5 shown, the embodiment provides a battery replacement platform 1 installed on a battery replacement trolley, used to provide a platform for replacing a battery from the bottom of an electric vehicle. When replacing the battery, the battery replacement trolley moves to the bottom of the vehicle, and the depleted battery at the bottom of the vehicle is disassembled and placed on the battery replacement platform 1; or the battery replacement platform 1 is raised to install the full battery placed thereon to the bottom of the vehicle.

[0074] The battery replacement platform 1 includes a base plate 2, a battery positioning assembly 3 and a vehicle body positioning assembly 4 arranged on the base plate 2, the battery positioning assembly 3 is used to drive the battery to move horizontally, the vehicle body positioning assembly 4 is used to move horizontally to determine the position of the battery replacement platform 1 relative to the vehicle body, and the projections of the battery positioning assembly 3 and the vehicle body positioning assembly 4 on the base plate 2 do not overlap.

[0075] The battery replacement platform 1 is designed in this way, so that the two horizontally moving positioning assemblies (the battery positioning assembly 3 and the vehicle body positioning assembly 4) can be arranged on the same horizontal plane, without using an arrangement with a high-low position difference, thereby reducing the overall height of the battery replacement platform 1 and increasing the operation space for battery replacement.

[0076] Among them, as Figure 2As shown, the battery positioning assembly 3 includes a battery positioning plate 31 having a receiving space 310 and a battery positioning driver 32 for driving the battery positioning plate 31 to move, and the vehicle body positioning assembly 4 includes a vehicle body positioning plate 41 extending into the receiving space 310 of the battery positioning plate 31 and a vehicle body positioning driver 42 disposed in the receiving space 310 and for driving the vehicle body positioning plate 41 to move. In the embodiment, the battery positioning driver 32 and the vehicle body positioning driver 42 are two driving motors.

[0077] The battery positioning plate 31 extends the vehicle body positioning plate 41 into the receiving space 310 and the vehicle body positioning driver 42 is disposed in the receiving space 310, so that the battery positioning plate 31 and the vehicle body positioning plate 41 are staggered and not overlapped in the horizontal plane, and the components of the battery positioning assembly 3 and the vehicle body positioning assembly 4 are dispersedly arranged, so that the layout in the horizontal plane is more compact, and it is easy to reduce the overall height of the battery swap platform 1.

[0078] There are many forms of structures to achieve the non-overlapping projection of the battery positioning assembly 3 and the vehicle body positioning assembly 4 on the base plate 2. In other embodiments, the battery positioning plate 31 and the vehicle body positioning plate 41 can have different shapes and structures according to the specific arrangement of the components on the battery swap platform 1, and are not limited to the structure form of the embodiment.

[0079] In the embodiment, the battery positioning assembly 3 includes two battery positioning plates 31 arranged at intervals and independent of each other, and the area 311 or the outer edge area 312 between the two battery positioning plates 31 forms the receiving space 310; that is, the receiving space 310 includes two area parts, one is the middle area 311 between the two battery positioning plates 31, and the other is the outer edge area 312 of the two battery positioning plates 31. The two battery positioning plates 31 are respectively connected by independent battery positioning drivers 32.

[0080] The battery positioning assembly 3 adopts two spaced-apart and independent battery positioning plates 31 instead of one integral battery positioning plate 31, which is convenient for processing. The two battery positioning plates 31 are respectively driven and connected by independent battery positioning drives 32, so that the battery positioning drives 32 can be small, which is conducive to reducing the height occupied by the battery positioning drives 32. In addition, small-sized drive motors have lower costs and are easy to purchase. Moreover, when the components carried by the battery positioning plates 31 are relatively heavy and need to be driven by two battery positioning drives 32, the two battery positioning plates 31 are respectively driven and connected by independent battery positioning drives 32, which can also avoid the situation that the inconsistent movement of two drives driving the same battery positioning plate will cause damage to the drives, effectively protecting the normal work of the drives. The accommodation space 310 is formed between the two battery positioning plates 31 and the outer edge area, and the accommodation space 310 can be used to accommodate the part (i.e., the first protruding part 411) of the vehicle body positioning plate 41 extending to the battery positioning plate 31, the vehicle body positioning drive 42 and other components, further improving the space in which the battery positioning assembly 3 and the vehicle body positioning assembly 4 can be staggered with each other, optimizing the layout, thereby being conducive to reducing the overall height of the battery swap platform 1.

[0081] Under the condition that the projections of the battery positioning plate 31 and the vehicle body positioning plate 41 on the base plate 2 do not overlap, the battery positioning plate 31 and the vehicle body positioning plate 41 can have different shapes and structural forms according to the needs of structural cooperation. For example, in other embodiments, the battery positioning plate 31 can also be an integral plate, and the accommodation space 310 capable of accommodating the vehicle body positioning drive 42 or other components can be dug out at the middle position and the outer side edge of the integral plate; or the battery positioning plate 31 can be divided into a larger number of plates. Similarly, the vehicle body positioning plate 41 can be the integral plate of the present embodiment, or can be two separate plates.

[0082] Among them, the vehicle body positioning plate 41 includes a first protruding part 411 extending to the accommodation space 310 between the two battery positioning plates 31, and the vehicle body positioning drive 42 is arranged between the two battery positioning plates 31 and connected with the bottom surface of the first protruding part 411.

[0083] In other embodiments, the vehicle body positioning plate 41 can also not have the first protruding part 411, but the output end of the vehicle body positioning driver 42 is connected to other areas outside the accommodation space 310, but this structure is not as effective as the embodiment of the battery swap platform 1, which places the first protruding part 411 of the vehicle body positioning plate 41 and the vehicle body positioning driver 42 in the accommodation space 310 between the two battery positioning plates 31 and connects them, effectively utilizing the space between the two independent battery positioning plates 31, optimizing the layout, and facilitating the reduction of the overall height of the battery swap platform 1. The connection position of the vehicle body positioning driver 42 and the first protruding part 411 is the bottom surface of the first protruding part 411, rather than the top surface, so that the vehicle body positioning plate 41 and the battery positioning plate 31 meet the non-overlapping projection while the vehicle body positioning plate 41 can be slightly higher than the battery positioning plate 31, so that there is more horizontal movement space when the first protruding part 411 moves without interfering with the battery positioning plate 31, that is, the vehicle body positioning plate 41 does not have to increase the spacing to avoid interference with the battery positioning plate 31 when the first protruding part 411 moves, so that the battery swap platform 1 does not have to be made very large in the movement direction of the battery positioning plate 31 (i.e. the movement direction A of the battery positioning assembly).

[0084] In this embodiment, the vehicle body positioning assembly 4 includes two vehicle body positioning drivers 42, which are arranged side by side and are both arranged between the two battery positioning plates 31. Two vehicle body positioning drivers 42 are used instead of one large vehicle body positioning driver 42, and the vehicle body positioning driver 42 can be small, which is conducive to reducing the height occupied by the vehicle body positioning driver 42. Similar to the two small battery positioning drivers 32, the vehicle body positioning driver 42 uses a small size driving motor, which is lower in cost and easier to purchase.

[0085] In this embodiment, the vehicle body positioning driver 42 is mostly arranged in the accommodation space 310 between the two battery positioning plates 31, achieving partial overlap in the height direction. In other embodiments, depending on the structure, the vehicle body positioning driver 42 can also be completely overlapped with the battery positioning plate 31 in the height direction. Such an arrangement reduces the space occupied by the vehicle body positioning driver 42 in the height direction, which is conducive to reducing the overall height of the battery swap platform 1.

[0086] In this embodiment, the connection piece 33 is a square block, with both ends of the square block spanning the accommodation groove 314 and being connected to the top surface of the battery positioning plate 31.

[0087] The battery positioning driver 32 is arranged in the accommodating groove 314 of the battery positioning plate 31, which reduces the space occupied by the battery positioning driver 32 in the height direction, and is conducive to reducing the overall height of the battery swap platform 1. The battery positioning driver 32 is connected to the top surface of the battery positioning plate 31 from the top, and the connection structure of the two (the battery positioning driver 32 and the battery positioning plate 31) does not occupy the space below the battery positioning plate 31, but uses the existing space above the battery positioning plate 31 (the existing space for carrying the battery) to reduce the overall height of the battery positioning assembly 3.

[0088] The battery positioning assembly 3 further comprises a battery positioning guide mechanism 34 arranged on both sides of each battery positioning plate 31, and the battery positioning guide mechanism 34 comprises at least two guide rails 341 arranged on the base plate 2 and a plurality of first sliding blocks 342 arranged on the bottom surface of the battery positioning plate 31 and in sliding fit with the guide rails 341. The sliding fit of the guide rails 341 and the first sliding blocks 342 achieves the movement guide of the battery positioning plate 31. The battery positioning guide mechanism 34 is arranged on both sides of the battery positioning plate 31, which is staggered with the components between the two battery positioning plates 31, and optimizes the layout in the horizontal plane.

[0089] As shown in Figure 2 each battery positioning plate 31 is recessed inwardly at the outer edge of one end close to the vehicle body positioning plate 41 to form an avoidance area 313 as an accommodating space 310, and the guide rail 341 of the battery positioning guide mechanism 34 arranged at the outer edge of each battery positioning plate 31 is a shared guide rail 341 extending through the avoidance area 313 to below the vehicle body positioning plate 41; there is one battery positioning guide mechanism 34 on the outer edge side of each of the two battery positioning plates 31, and thus there are two shared guide rails 341. The vehicle body positioning plate 41 comprises a second protruding portion 412 extending into the avoidance area 313, and the vehicle body positioning assembly 4 further comprises a vehicle body positioning guide mechanism 43, which comprises a second sliding block 44 arranged on the bottom surface of the second protruding portion 412 and in sliding fit with the shared guide rail 341.

[0090] In such a structure, the avoidance area 313 and the second protruding portion 412 cooperate to form a staggered arrangement structure, and the outer edge of the battery positioning plate 31 and the vehicle body positioning plate 41 do not overlap in the projection direction. The shared guide rail 341 is arranged at the outer edge of the battery positioning plate 31 to connect the battery positioning plate 31 and the vehicle body positioning plate 41, which does not occupy the space inside the battery positioning plate 31 and between the two battery positioning plates 31, optimizes the layout in the horizontal plane, and realizes the consistency of the guide of the battery positioning assembly 3 and the vehicle body positioning assembly 4 through the shared guide rail 341, thereby improving the guide accuracy and precision. The second sliding block 44 and the shared guide rail 341 are in sliding fit, which achieves the movement guide of the vehicle body positioning plate 41.

[0091] wherein, as shown in Figure 1 and Figure 4 , Figure 5 The battery replacement platform 1 further comprises a tray assembly 5 floatingly connected to the upper side of the battery positioning assembly 3, the tray assembly 5 is used for carrying batteries, and the tray assembly 5 is connected to the battery positioning plate 31 through a plurality of spring floating members 35 provided on the battery positioning plate 31, and the plurality of spring floating members 35 are evenly arranged in the outer edge area of the two battery positioning plates 31.

[0092] The tray assembly 5 is connected to the battery positioning plate 31 through the spring floating members 35, which facilitates floating adjustment of the position of the battery during battery replacement and realizes positioning. The plurality of spring floating members 35 are evenly arranged in the outer edge area of the two battery positioning plates 31, which facilitates maintenance of the drive in the central area of the tray assembly 5.

[0093] As shown in Figure 2 , Figure 5 Each battery positioning plate 31 is provided with a clamping groove 36 on the plate body in front of the battery positioning drive 32 along the moving direction of the battery positioning plate 31 (i.e. the moving direction A of the battery positioning assembly), and the clamping groove 36 is used for matched connection with the clamping plate 53 on the bottom surface of the tray assembly 5. Through the matched connection of the clamping groove 36 and the clamping plate 53, the detachable connection of the battery positioning plate 31 and the tray assembly 5 is realized, and the clamping structure is rigidly connected, which is matched with the floating connection realized through the spring floating members 35, so as to realize floating adjustment and locking of the position of the battery.

[0094] As shown in Figure 4 and Figure 5 The tray assembly 5 comprises two horizontal plates 51 arranged along the moving direction of the battery positioning assembly 3 (i.e. the moving direction A of the battery positioning assembly), and the two horizontal plates 51 are fixedly connected through a plurality of vertical plates 52; the horizontal plate 51 is one-to-one correspondingly embedded in the spring floating member 35 through a plurality of convex columns 54; and the battery positioning drive 32 and the vehicle body positioning drive 42 are arranged to avoid the plurality of vertical plates 52. In such a structure, the horizontal plate 51 and the vertical plate 52 respectively position the position between the tray and the battery positioning plate 31 from two directions; wherein the horizontal plate 51 is one-to-one correspondingly embedded in the spring floating member 35 through a plurality of convex columns 54, so as to realize the floating connection of the tray assembly 5 and the battery positioning plate 31, so that the carried battery can be adjusted in position as needed, facilitating the guiding during disassembly and installation of the battery. The battery positioning drive 32 and the vehicle body positioning drive 42 are arranged to avoid the plurality of vertical plates 52, which can avoid the installation position of the battery positioning drive 32 and the vehicle body positioning drive 42, facilitating maintenance; at the same time, the battery positioning drive 32 and the vehicle body positioning drive 42 do not occupy additional space in the height direction, which is conducive to reducing the overall height of the battery replacement platform 1.

[0095] As shown in Figure 5 The lower surface of the transverse plate 51 is provided with an unlocking device 55 and a vision sensor 56, the unlocking device 55 is used in cooperation with the locking mechanism of the underbody battery to unlock or lock the battery, and the vision sensor 56 is used to detect whether the locking mechanism of the underbody battery is locked in place; the unlocking device 55 and the vision sensor 56 are arranged in the accommodation space 310 of the outer edge area of the two battery positioning plates 31.
