[0029] The following disclosure provides many different embodiments or examples for implementing different structures of the present utility model.

[0030] Currently, the sheet metal surface of the battery swapping cabinet is spray-coated with a protective layer, and the ground wire is conducted through welding screws to connect the wires. Welding is required at both ends of the wire, and the welding screws also need to be masked. The welding screws and wires are also prone to interference with other structures and need to be avoided. Based on this, the present utility model proposes a grounding device and a battery swapping cabinet, which will be described below in combination with Figures 1-6 Describe the grounding device and battery swapping cabinet of the present utility model.

[0031] The grounding device 10 provided by the embodiment of the present utility model includes: a fixing member 11 and an installation component. The outer wall surface of the fixing member 11 is spray-coated with a protective layer. The fixing member 11 is provided with a first installation hole, and the inner wall surface of the first installation hole is conductive; the installation component includes a grounding member 12, the grounding member 12 is provided with a second installation hole, and the grounding member 12 is conducted with the fixing member 11 through a metal fastener 15 that sequentially passes through the second installation hole and the first installation hole; wherein at least one electrical component is provided on the grounding member 12, and the electrical component is conducted with the grounding member 12.

[0032] As Figure 1 And Figure 2 Shown, the fixing member 11 is arranged inside the electric control cabinet. The cabinet body 20 of the battery swapping cabinet generally uses cold-rolled steel plates. The fixing member 11 can be an angle steel with poor corrosion resistance and needs to be treated with a plastic spraying surface treatment, such as spraying plastic powder, and the plastic powder is not conductive. The fixing member 11 is provided with a first installation hole for installing the installation component. It can be understood that when the fixing member 11 is arranged on the inner wall surface of the battery swapping cabinet, it does not affect the installation of the installation component. For example, part of the fixing member 11 coincides with the inner wall surface of the battery swapping cabinet, and part protrudes from the inner wall surface of the battery swapping cabinet, which is convenient for installing the installation component. It should be noted that the inner wall surface of the first installation hole is conductive. When performing plastic spraying treatment on the surface of the battery swapping cabinet and the fixing member 11, the first installation hole can be shielded. The first installation hole is a threaded hole. During plastic spraying treatment, a bolt is installed in the threaded hole, and the bolt is removed after the plastic spraying is completed, so as to achieve shielding. At this time, the inner wall surface of the first installation hole is conductive.

[0033] There is at least one electrical component provided on the grounding member 12, such as a charging component, a main control board, etc.; each electrical component is electrically connected to the grounding member 12. The grounding member 12 has good electrical conductivity and corrosion resistance. There is a second mounting hole provided on the grounding member 12, and the metal fastener 15 passes through the second mounting hole and the first mounting hole in sequence to achieve the grounding connection between the grounding member 12 and the fixing member 11, thereby realizing the grounding connection between the electrical component and the battery swapping cabinet.

[0034] The grounding device 10 provided by the embodiment of the present utility model realizes the grounding connection between one or more electrical components and the battery swapping cabinet by providing one or more electrical components on the grounding member 12 and grounding the grounding member 12 and the fixing member 11 through the metal fastener 15, which simplifies the connection method, is convenient for installation, and reduces the manufacturing and production costs.

[0035] Compared with the prior art solution of using welded screws and wires to achieve grounding connection, the embodiment of the present utility model can achieve the grounding connection of one or more electrical components through one grounding member 12, with low labor cost and material cost, and can also save time.

[0036] Such as Figure 3 and Figure 4 As shown, the mounting assembly provided by the embodiment of the present utility model further includes a mounting plate 13. The grounding member 12 is welded to the mounting plate 13. There is a third mounting hole provided on the mounting plate 13, and the inner wall surface of the third mounting hole is non-conductive. The third mounting hole is coaxially arranged with the second mounting hole; the electrical component is mounted on the mounting plate 13.

[0037] Specifically, the grounding member 12 is welded to the mounting plate 13, and at this time, the grounding member 12 is electrically connected to the mounting plate 13. The electrical component is mounted on the mounting plate 13 and is electrically connected to the ground wire of the mounting plate 13. There is a third mounting hole provided on the mounting plate 13 that matches the second mounting hole. The third mounting hole can be a slot hole or a through hole. The third mounting hole is coaxially arranged with the second mounting hole, and it is only necessary to facilitate the metal fastener 15 to pass through the third mounting hole and enter the first mounting hole to achieve the connection.

[0038] The grounding member 12 is welded to the mounting plate 13 to achieve electrical connection, and the electrical component is mounted on the mounting plate 13, which can save the size of the grounding member 12 and save costs. It should be noted that when the mounting plate 13 needs to be spray-painted, the grounding member 12 needs to be shielded. At this time, the third mounting hole is also spray-painted, and the mounting plate 13 and the fixing plate cannot be directly electrically connected. Therefore, the electrical connection is achieved through the grounding member 12 welded on the mounting plate 13 and the metal fastener 15. In addition, during spray-painting, the distance between the second mounting hole and the opposite surface of the mounting surface of the grounding member 12 is far, and the plastic powder hardly enters the second mounting hole; or, a filling object is used for shielding. In addition, the metal fastener 15 can also be grounded and connected to the fixing member 11 through the surface of the grounding member 12.

[0039] In the embodiment of the present utility model, at least one welding post is provided at the bottom of the grounding member 12. The grounding member 12 is welded to the mounting plate 13 through the welding post, which can prevent the grounding member 12 from being welded through and can also isolate the grounding member 12 from the mounting plate 13. To ensure the stability of the grounding member 12, the number of grounding posts can be 3 or 4.

[0040] Further, for the convenience of installation, there are multiple mounting components in the embodiment of the present utility model. The user can adjust the position of the mounting components by adjusting the position of the fixing member 11, or reduce the number of electrical components in case of insufficient space according to the position of the overall space, and can adjust the size of the mounting components and increase the number of mounting components.

[0041] As Figure 5 and Figure 6 shown, in the embodiment of the present utility model, the first mounting hole on the fixing member 11 can be a threaded hole. A nut 14 is welded to the bottom of the fixing member 11. The nut 14 is coaxially arranged with the threaded hole. When the fixing member 11 is spray-coated, the nut is shielded. The metal fastener 15 sequentially passes through the second mounting hole on the grounding member 12, the third mounting hole on the mounting plate 13, and the threaded hole, and is threadedly connected to the nut 14 to realize the grounding conduction between the grounding member 12 and the fixing member 11, that is, the grounding conduction between the electrical components on the mounting plate 13 and the fixing member 11.

[0042] The embodiment of the present utility model also provides a battery swapping cabinet, which includes the grounding device 10 in any of the above embodiments. The battery swapping cabinet further includes a cabinet body 20. The grounding device 10 includes a fixing member 11, and the grounding device 10 is fixed to the cabinet body 20 through the fixing member 11.

[0043] As Figure 1 and Figure 2 shown, the fixing member 11 is fixed on the cabinet body 20. The cabinet body 20 of the battery swapping cabinet is generally made of cold-rolled steel plate. The fixing member 11 can be an angle steel, which has poor corrosion resistance and needs to be subjected to spray coating surface treatment, such as spraying plastic powder, and the plastic powder is not conductive. The fixing member 11 is provided with a first mounting hole for mounting the mounting components. It can be understood that when the fixing member 11 is arranged on the inner wall surface of the battery swapping cabinet, it does not affect the installation of the mounting components.

[0044] Further, the battery swapping cabinet further includes at least one electrical component. The mounting component includes a mounting plate 13 and a grounding member 12. The grounding member 12 is welded to the mounting plate 13, and the grounding member 12 is conducted with the mounting plate 13. The electrical component is mounted on the mounting plate 13, and the electrical component is conducted with the ground wire of the mounting plate 13, that is, the electrical component is conducted with the grounding member 12. Further, the grounding member 12 is connected and conducted with the fixing member 11 through the metal fastener 15, so as to realize the grounding conduction between the electrical component and the cabinet body 20.

[0045] The electrical components in the embodiment of the present utility model include a charging component and a main control board.

[0046] In the embodiment of the present utility model, a sliding assembly 21 is further provided at the bottom of the cabinet body 20. The sliding assembly 21 can be a lockable pulley, which is convenient for adjusting and locking the position of the cabinet body 20 as needed.

[0047] The battery swapping cabinet of the embodiment of the present utility model further includes a limiting member 22. The first end of the limiting member 22 is connected to the outer wall surface of the cabinet body 20. The limiting member 22 can rotate or slide around the cabinet body 20. When the cabinet body 20 is slid to move, the limiting member 22 is rotated or slid upward, and the limiting member 22 is separated from the ground; after the movement is completed, the limiting member 22 is rotated in the reverse direction or slid downward, and the second end of the limiting member 22 contacts the ground. The limiting member 22 can be fixed to the ground through a fastener to prevent the cabinet body 20 from moving.

[0048] The limiting member 22 includes a first limiting member, a second limiting member, a third limiting member, and a fourth limiting member. The first limiting member and the second limiting member are respectively arranged on both sides of the cabinet body 20 in the first direction, and the first limiting member and the second limiting member cooperate to limit the movement of the cabinet body 20 in the first direction. The third limiting member and the fourth limiting member are respectively arranged on both sides of the cabinet body 20 in the second direction, and the third limiting member and the fourth limiting member cooperate to limit the movement of the cabinet body 20 in the second direction.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
