[0036] The following description is intended to disclose the present disclosure so that those skilled in the art can implement the present disclosure. The preferred embodiments described below are for illustrative purposes only, and those skilled in the art may readily conceive of other obvious variations. The basic principles of the present disclosure defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present disclosure.

[0037] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0038] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0039] In this disclosure, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections, electrical connections, or communication; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of these terms in this disclosure based on specific circumstances.

[0040] In the related art, battery pack gripping and transfer are usually completed by a robot, which automatically grips and transfers the battery pack when driven. However, the robot device has a complex structure, many parts, and high cost.

[0041] In view of this, the battery pack clamp provided by the present disclosure is capable of clamping the battery pack, and has a simple structure, few parts, and low cost.

[0042] Figure 1 It is a schematic structural diagram of the battery pack clamp of the first embodiment of the present disclosure. Figure 2 Schematic diagram of a top view of a battery pack clamp according to the first embodiment of the present disclosure. Figure 1 and Figure 2 The battery pack clamp of the embodiment of the present disclosure includes a first operating member 10 and a second operating member 20.

[0043] Two ends of the first operating member 10 form a first operating portion 11 and a first clamping portion 12 respectively.

[0044] The second operating member 20 is hinged to the first operating member 10 in a cross-connected manner. In other words, the second operating member 20 is arranged to cross the first operating member 10, and the first operating member 10 and the second operating member 20 can rotate relative to each other around the intersection.

[0045] The second operating member 20 has a second operating portion 21 and a second clamping portion 22 at its two ends. The proximity between the first operating portion 11 and the second operating portion 21 forms the proximity between the first clamping portion 12 and the second clamping portion 22, forming a clamping space 101 for the battery pack 900.

[0046] In other words, when the battery pack clamp clamps the battery pack 900, the first clamping part 12 and the second clamping part 22 are first placed on opposite sides of the battery pack 900, and then the first operating part 11 and the second operating part 21 are operated to rotate closer to each other, and the first clamping part 12 and the second clamping part 22 are also rotated closer, so that the first clamping part 12 and the second clamping part 22 can be close to the opposite sides of the battery pack 900 respectively, until the first clamping part 12 and the second clamping part 22 are respectively in contact with the opposite sides of the battery pack 900, and the first clamping part 12 and the second clamping part 22 cooperate to clamp the battery pack 900.

[0047] In this way, when the first clamping portion 12 and the second clamping portion 22 cooperate to clamp the battery pack 900, the battery pack clamp is moved and the battery pack 900 is clamped and moved accordingly. The battery pack clamp disclosed in the present invention has a simple structure, few parts, and low cost.

[0048] Optionally, the first operating member 10 and the second operating member 20 are arranged in a vertical plane. The first operating portion 11 is located above the first clamping portion 12. The second operating portion 21 is located above the second clamping portion 22. Thus, when the first operating member 10 and the second operating member 20 are operated, the first operating portion 11 and the second operating portion 21 are lifted upward respectively, and the first operating portion 11 and the second operating portion 21 rotate toward each other, thereby causing the first clamping portion 12 and the second clamping portion 22 to rotate toward each other and cooperate to clamp the battery pack 900.

[0049] Specifically, battery packs 900, especially those used in new energy vehicles, are typically large in size and weight. Therefore, to clamp the battery pack 900, two people can stand adjacent to the first operating portion 11 and the second operating portion 21, respectively. Then, the two people can lift the first operating portion 11 and the second operating portion 12 upward, respectively, so that the first clamping portion 12 and the second clamping portion 22 cooperate to clamp the battery pack 900, and when the battery pack clamp is moved, the battery pack 900 is clamped and transferred accordingly.

[0050] Optionally, the first operating member 10 and the second operating member 20 may be integrally formed. The first operating portion 11 and the first clamping portion 12 are integrally formed at both ends of the first operating member 10. The second operating portion 21 and the second clamping portion 22 are integrally formed at both ends of the second operating member 20. The first operating member 10 and the second operating member 20 are high in strength and have a long service life.

[0051] Of course, the first operating member 10 and the second operating member 20 can also be assembled from multiple parts. The first operating portion 11 and the first clamping portion 12 are assembled, for example, by welding or detachably connecting them to the ends of the first operating member 10. The second operating portion 21 and the second clamping portion 22 are assembled, for example, by welding or detachably connecting them to the ends of the second operating member 20. The manufacturing process of the first operating member 10 and the second operating member 20 is mature and the manufacturing cost is low.

[0052] Optionally, the first operating member 10 includes a first lower rod 13 and a first upper rod 14. The first clamping portion 12 is formed at the lower end of the first lower rod 13. One end of the first upper rod 14 is connected to the upper end of the first lower rod 13 at an angle, and the other end is provided with the first operating portion 11.

[0053] The second operating member 20 includes a second lower rod 23 and a second upper rod 24. The second clamping portion 22 is formed at the lower end of the second lower rod 23. One end of the second upper rod 24 is connected to the upper end of the second lower rod 23 at an angle, and the other end is provided with the second operating portion 21. The second upper rod 24 extends away from the first upper rod 14. As a result, the distance between the first operating portion 11 and the second operating portion 21 is relatively large, providing ample operating space around each of the first and second operating portions 11, 21, allowing two people to operate the first and second operating portions 11, 21 independently without interference.

[0054] For example, the connection angle between the second upper rod 24 and the second lower rod 23 is an obtuse angle, and the connection angle between the first upper rod 14 and the first lower rod 13 is an obtuse angle.

[0055] Figure 3 1 is a schematic cross-sectional view of a battery pack clamp according to the first embodiment of the present disclosure. Figure 3 The first operating member 10 and the second operating member 20 are hollow structures. Therefore, the first operating member 10 and the second operating member 20 are light in weight and easy to move, thereby driving the clamped battery pack 900 to move in conjunction.

[0056] Optionally, the first operating member 10 and the second operating member 20 are made of metal material, which has high strength and long service life.

[0057] Optionally, see Figure 1 and Figure 2 The first clamping portion 12 includes a first clamping plate 121. The second clamping portion 22 includes a second clamping plate 221. The first clamping plate 121 and the second clamping plate 221 are in a vertical state when clamping the battery pack 900. Therefore, when the first clamping portion 12 and the second clamping portion 22 cooperate to clamp the battery pack 900, the first clamping plate 121 and the second clamping plate 221 can be respectively attached to the opposite two sides of the battery pack 900, so that the first clamping plate 121 and the second clamping plate 221 cooperate to clamp the battery pack 900, and the clamping effect of the battery pack 900 is good.

[0058] Optionally, see Figure 1 and Figure 2 , the first clamping part 12 also includes a first limiting plate 122. The first limiting plate 122 is arranged on the side of the first clamping plate 121. The second clamping part 22 also includes a second limiting plate 222. The second limiting plate 222 is arranged on the side of the second clamping plate 221. And the second limiting plate 222 and the first limiting plate 122 are located on the same side of the clamping space 101. Therefore, when the first clamping part 12 and the second clamping part 22 cooperate to clamp the battery pack 900 and carry the battery pack 900 to move, the first limiting plate 122 and the second limiting plate 222 can cooperate to limit the battery pack 900, preventing the battery pack 900 from escaping from the clamping space 101 from the space on the side where the first limiting plate 122 and the second limiting plate 222 are located.

[0059] Optionally, at least one of the first clamping portion 12 and the second clamping portion 22 is provided with a connector that can be plugged into and mated with a mating portion of the battery pack 900. Thus, when the first clamping portion 12 and the second clamping portion 22 cooperate to clamp the battery pack 900, the connector plugs into and mated with a mating portion on the outer wall of the battery pack 900, thereby improving the stability of the battery pack 900 when being clamped and carried, and making it difficult for the clamped battery pack 900 to suddenly break away from the first clamping portion 12 and the second clamping portion 22.

[0060] Specifically, see Figure 1 and Figure 2 The first clamping portion 12 is provided with at least one first connector 123. The first connector 123 engages with the first mating portion 91 on the outer wall of the battery pack 900. Thus, when the first clamping portion 12 and the second clamping portion 22 cooperate to clamp the battery pack 900, the engagement between the first connector 123 and the first mating portion 91 enhances the connection strength between the battery pack 900 and the first clamping portion 12, making it difficult for the battery pack 900 to suddenly detach from the first clamping portion 12.

[0061] The second clamping portion 22 is provided with at least one second connecting member 223. The second connecting member 223 engages with the second mating portion 92 on the outer wall of the battery pack 900. Thus, when the first clamping portion 12 and the second clamping portion 22 cooperate to clamp the battery pack 900, the engagement of the second connecting member 223 with the second mating portion 92 enhances the connection strength between the battery pack 900 and the second clamping portion 22, making it difficult for the battery pack 900 to suddenly detach from the second clamping portion 22.

[0062] Optionally, one of the connector and the mating portion is formed with a convex portion, and the other is formed with a concave portion that can be plugged into and mated with the convex portion. For example, the connector is formed with a convex portion, and the mating portion is formed with a concave portion that can be plugged into and mated with the convex portion. Alternatively, the connector is formed with a concave portion, and the mating portion is formed with a convex portion that can be plugged into and mated with the concave portion. Thus, through the mating of the convex portion and the concave portion, the connector and the mating portion are plugged into and mated with each other.

[0063] Optionally, at least one of the first clamping portion 12 and the second clamping portion 22 is formed with a plurality of installation positions, and the connecting member is switchably arranged between the plurality of installation positions.

[0064] Specifically, the first clamping portion 12 is provided with a plurality of first mounting positions 1201, and at least one of the first mounting positions 1201 is provided with a first connector 123 that can be switched between the plurality of first mounting positions 1201, so as to be plugged and mated with the first mating portions 91 at different positions of different battery packs 900. And / or the second clamping portion 22 is provided with a plurality of second mounting positions 2201, and at least one of the second mounting positions 2201 is provided with a second connector 223 that can be switched between the plurality of second mounting positions 2201, so as to be plugged and mated with the second mating portions 92 at different positions of different battery packs 900.

[0065] Therefore, since the connector can be switched between multiple installation positions, the connector can be plugged into and matched with the mating parts at different positions of different battery packs 900, so that the battery pack clamp can clamp different types of battery packs 900 with different mating parts at different positions, making the battery pack clamp have a wider range of applications.

[0066] Optionally, a plurality of mounting holes are provided at the plurality of mounting positions, and the connecting member is suitable for being detachably mounted in each of the mounting holes.

[0067] Specifically, see Figure 1 A plurality of first mounting holes are provided at the plurality of first mounting positions 1201, and the first connecting member 123 is adapted to be detachably mounted in each of the first mounting holes. Thus, when the first connecting member 123 is switched to be installed in a different first mounting hole, the first connecting member 123 is switched between the plurality of first mounting positions 1201.

[0068] A plurality of second mounting holes are provided at the plurality of second mounting positions 2201, and the second connecting member 223 is adapted to be detachably mounted in each of the second mounting holes. Thus, when the second connecting member 223 is switched to be mounted in a different second mounting hole, the second connecting member 223 is switched between the plurality of second mounting positions 2201.

[0069] Thus, by forming a plurality of the mounting holes at a plurality of the mounting positions and by the coupling between the connecting member and the mounting holes, the connecting member can be switched between the plurality of the mounting positions.

[0070] Optionally, the connecting member is threadedly engaged with the mounting hole. Specifically, the first connecting member 123 is threadedly engaged with the first mounting hole. Thus, after the first connecting member 123 is screwed out of one first mounting hole and then screwed into another first mounting hole, the position of the first connecting member 123 is switched, making the position switching of the first connecting member 123 convenient.

[0071] The second connecting member 223 is threadedly engaged with the second mounting hole. Thus, the second connecting member 223 is screwed out of one second mounting hole and then screwed into another second mounting hole, thereby switching the position of the second connecting member 223. The position switching of the second connecting member 223 is convenient.

[0072] Thus, the position of the connecting member can be switched by screwing the connecting member out of or into the mounting hole, and the position switching of the connecting member is convenient.

[0073] Optionally, see Figure 1 and Figure 2 The battery pack fixture further includes a connecting shaft 30. The middle portions of the first operating member 10 and the second operating member 20 are rotatably sleeved on the outside of the connecting shaft 30. As a result, the first operating member 10 and the second operating member 20 can both rotate relative to each other around the connecting shaft 30, and the structure is simple.

[0074] Figure 4 yes Figure 3 An enlarged diagram of part A in Figure 2. Figure 3 and Figure 4 The battery pack fixture further includes a first friction-enhancing sleeve 40 . The first friction-enhancing sleeve 40 is sleeved on the outside of the first operating part 11 .

[0075] Figure 5 yes Figure 3 An enlarged schematic diagram of part B in FIG. Figure 3 and Figure 5 The battery pack fixture further includes a second friction-enhancing sleeve 50 . The second friction-enhancing sleeve 50 is sleeved on the outside of the second operating portion 21 .

[0076] Therefore, when operating the first operating part 11 and / or the second operating part 21, the first friction-enhancing sleeve 40 and / or the second friction-enhancing sleeve 50 can increase friction and prevent slipping and separation, ensuring that the first operating part 11 and / or the second operating part 21 can be operated correctly and smoothly.

[0077] Optionally, the first friction-enhancing sleeve 40 and / or the second friction-enhancing sleeve 50 are made of a soft material, such as rubber, so that when a technician manually operates the first operating part 11 and / or the second operating part 21, the operation is comfortable.

[0078] Figure 6 This is a front view of the battery pack clamp of the second embodiment of the present disclosure when it is partially exploded. Figure 6The battery pack clamp further includes an angle limiting member 60. The angle limiting member 60 is connected to the first operating member 10 and the second operating member 20 respectively, thereby limiting the intersection angle between the first operating member 10 and the second operating member 20.

[0079] Therefore, when two people respectively operate the first operating part 11 and the second operating part 21, so that the first clamping part 12 and the second clamping part 22 cooperate to clamp the battery pack, and before carrying the battery pack for transfer, the angle limiting part 60 is respectively installed on the first operating part 10 and the second operating part 20, so as to limit the intersection angle of the first operating part 10 and the second operating part 20, so that the intersection angle between the first clamping part 12 and the second clamping part 22 can be maintained in the clamping state, so that when two people operate the first operating part 11 and the second operating part 21 and carry the battery pack to move, the first clamping part 12 and the second clamping part 22 can maintain the state of clamping the battery pack more stably.

[0080] Optionally, the angle limiting member 60 includes a first inserting portion 61, a second inserting portion 62, and a connecting portion 63. The first inserting portion 61 is inserted into and extends out of the first inserting hole 1301 of the first operating member 10. The second inserting portion 62 is inserted into and extends out of the second inserting hole 2301 of the second operating member 20. The connecting portion 63 is connected between the first inserting portion 61 and the second inserting portion 62.

[0081] Therefore, when the first plug-in portion 61 is plugged into and extends out of the first plug-in hole 1301, and the second plug-in portion 62 extends out of the second plug-in hole 2301, due to the limitation of the connecting portion 63, the intersection angle between the first operating member 10 and the second operating member 20 is difficult to change, and the first operating portion 11 and the second operating portion 21 are also difficult to rotate closer to or away from each other, thereby enabling the battery pack clamp to clamp the battery pack more stably.

The advantages of the present disclosure have been fully and effectively realized.
