[0036] The following combination Figures 1 to 5 , describing the embodiments of the present utility model.

[0037] According to an embodiment of the present invention, on the one hand, a battery replacement device is provided, including: a battery assembly 1 and a matching device, the matching device is arranged on the top of the battery assembly 1, the matching device includes a matching frame 2 and a cooling assembly 3, the matching frame 2 has an installation position inside, the matching frame 2 has a matching structure 201 for matching with the transfer equipment, and the cooling assembly 3 is arranged in the installation position.

The matching frame 2 can accommodate the installation of the cooling assembly 3 inside, and also has a matching structure 201 for matching with the transfer equipment. A single matching device has both the matching function during transportation and the cooling function of the battery assembly 1, which effectively reduces the number of components in the battery replacement device. While lowering its own height, it also reduces its own weight by reducing the number of mounting frames, effectively solving the problem of large volume and weight of existing replaceable batteries.

[0039] It should be noted that the top refers to Figure 1 The arrow in the middle points to the "upward" part.

[0040] There is no limitation on the specific form of the cooling component 3 , which may be an air-cooled cooling component or a liquid-cooled cooling component, and can be flexibly selected according to needs.

[0041] Preferably, in order to ensure that the battery assembly 1 is reliably maintained at a suitable temperature during operation, the cooling assembly 3 is a liquid cooling assembly.

[0042] In one possible embodiment, the matching frame 2 includes a frame 202 and a matching structure 201 arranged on the top of the frame 202. The frame 202 has an installation position, and at least two matching structures 201 are arranged at intervals on the frame 202. The matching frame 2 has a simple and reliable structure. The two matching structures 201 arranged at intervals can match with the transfer device more stably, and the force is more evenly distributed, while also reducing the risk of detachment or overturning during transportation.

[0043] Specifically, there is no limitation on the specific form of the frame 202 , which may be a planar frame or a body-shaped frame, and can be flexibly selected according to actual needs.

[0044] In addition, there is no limitation on the specific form of the cooperating structure 201. It can be a rod-shaped structure or a block-shaped structure.

This compact arrangement allows the main components of the cooling assembly 3 to be more centrally located between the two mating structures 201, so that the center of gravity of the mating device can also be located between the two mating structures 201, reducing the risk of overturning during transportation.

[0046] The first direction refers to Figure 1 The arrow in the middle points to the "left" and "right" directions.

[0047] It can be understood that, as an alternative embodiment, the number of the matching structures 201 can also be more than two, and they can be arranged at intervals along the first direction.

[0048] In addition, since the main components of the cooling assembly 3 are more concentratedly located between the two matching structures 201, it can also optimize the connecting pipes between the components of the cooling assembly 3, and the connection between the various components can be completed using shorter and fewer connecting pipes.

[0049] Specifically, the two matching structures 201 may be eccentrically arranged on the frame 202 , or symmetrically arranged on the frame 202 .

The matching structure 201 close to the control part is a first matching structure, and the first matching structure and the control part are spaced apart, and the space between the two forms a first avoidance space 4. The matching structure 201 close to the heat exchange part is a second matching structure, and the second matching structure and the heat exchange part are spaced apart, and the space between the two forms a second avoidance space 5. The first avoidance space 4 and the second avoidance space 5 can provide an operating space for the transportation operation process to avoid the transfer equipment from contacting the components of the cooling component 3 when cooperating with the matching structure 201, thereby damaging the working components.

The support member 2014 is respectively connected to the guide member 2013 and the matching beam 2011, which can effectively improve the stability and durability of the guide member 2013 during the working process.

[0062] Specifically, if Figure 4 As shown, the support member 2014 is an L-shaped support rib.
