Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application. In addition, it should be understood that the specific implementation manners described herein are only used for illustrating and explaining the present application, and are not used for limiting the present application.

[0042] Please refer to Figures 1-2 , Figure 1 is a structural schematic diagram of a support provided by an embodiment of the present application Figure 1 , Figure 2 is an enlarged schematic diagram of a partial A of the support. The present application provides a support 100, which comprises a first support beam 20 and a support piece 10, the support piece 10 is used for supporting a battery pack 200, the support piece 10 comprises a first end and a second end arranged oppositely, the first end is movably supported on the first support beam 20, and the support 100 further comprises a second support beam 30 and an elastic piece 40, the second support beam 30 is arranged at intervals with the first support beam 20, and the elastic piece 40 is installed on the second support beam 30 and located on a moving path of the second end, so as to support the second end.

[0043] The elastic piece 40 absorbs the moving impact force or vibration from the battery pack 200, reduces the influence of the vibration of the equipment or system on the battery pack 200, and prevents damage or excessive wear. The elastic piece 40 can be a spring, an elastic gasket, an elastic bellows, etc., which is not limited in the present application.

[0044] In the related art, the battery pack support is a mechanical component used for supporting, fixing and protecting the battery pack 200. Since the battery pack 200 has a certain weight, when the battery pack 200 is installed to the support 100 for integration, the moving speed of the battery pack 200 is relatively fast, and the battery will suffer a certain impact during the moving process, which causes damage to the battery pack 200.

[0045] Therefore, the support 100 is provided, the first end of the support member 10 is movably supported on the first support beam 20, the second support beam 30 is provided with the elastic member 40, the elastic member 40 is located on the movement path of the second end, and the second end of the support member 10 is supported. By arranging the elastic member 40 on the movement path of the second end, the elastic member 40 plays a buffering effect during the movement of the battery pack 200 along the movement path, and the damage of the battery pack 200 caused by the vibration and impact in the system is reduced.

[0046] In some embodiments, the support member 10 has a first state and a second state. In the first state, the first end is supported on the first support beam 20, the second end is supported on the second support beam 30, and the second end and the elastic member 40 are spaced apart. In the second state, the support member 10 is elastically connected to the elastic member 40 to compress the elastic member 40.

[0047] Specifically, the extension direction of the first support beam 20 and the second support beam 30 is the vertical direction, and the direction perpendicular to the first support beam 20 and the second support beam 30 is the horizontal direction. The first state and the second state are two different states of the support member 10 when the battery pack 200 moves along the movement path.

[0048] In the first state, the second end of the elastic member 40 is spaced apart from the support member 10, and the support member 10 is not subjected to the force of the elastic member 40. At this time, the support member 10 and the battery pack 200 in the support member 10 can be in an inclined state, and the angle of the inclined angle between the support member 10 and each support beam is small, and the battery pack 200 is not in the balanced position. In the second state, the support member contacts and compresses the elastic member 40, at this time the elastic member 40 produces elastic deformation, the support member 10 is subjected to the reaction force of the spring force, the moving speed is gradually reduced, the support member 10 can be in an inclined state, but the angle of the inclined angle between the support member 10 and each support beam is larger, or the support beam is in a horizontal position.

[0049] In some embodiments, the support 100 includes two second support beams 30, the two second support beams 30 are spaced apart, each second support beam 30 is provided with a connecting portion 31, and the number of elastic members 40 is at least two. Each connecting portion 31 is provided with an elastic member 40.

[0050] Specifically, the connecting portion 31 is used to support and connect the elastic member 40, the first support beam 20 and the second support beam 30 are arranged in the vertical direction, the distance between the two first support beams 20 and the two second support beams 30 is the same, the connecting portion 31 can be protrudingly arranged on the second support beam 30 in the horizontal direction, and the elastic member 40 can be fixed to the connecting portion 31 by welding, bonding or the like, or can be fixed to the connecting portion 31 by clamping, inserting or the like. detachable manner, which is not limited in the present application.

[0051] Each connecting part 31 can be further provided with one or more elastic members 40 to increase the buffering effect.

[0052] In some embodiments, the elastic member 40 comprises a spring, and the elastic member 40 is welded to the connecting part 31. The spring absorbs external impact force by compression or extension, converts part of the impact energy into spring deformation, effectively slows down the impact speed, and reduces the direct impact of the impact force on the system.

[0053] In some examples, the spring comprises opposite free ends and fixed ends, the free ends of the spring can be retracted under the pressure of the support 10, and the fixed ends of the spring are welded to the connecting part 31, and the welding can provide a very strong connection. Compared with other connection methods, the welding process is relatively simple, which can realize lower production cost and reduce the need for other fasteners.

[0054] In some embodiments, each connecting part 31 comprises a first plate body 311 and a second plate body 312, the first plate body 311 is connected to the second support beam 30, the second plate body 312 is connected to the first plate body 311 and protrudes towards another connecting part 31.

[0055] Specifically, the first plate body 311 extends in the vertical direction and is fixed to the beam wall of the second support beam 30, and the second plate body 312 is connected to the first plate body 311 perpendicularly and extends in the horizontal direction and towards another second support beam 30, the first plate body 311 is used to connect the second support beam 30, and the side of the second plate body 312 away from the first plate body 311 is used to connect the spring, the mutual connection of the first plate body 311 and the second plate body 312 can increase the stability of the connecting part 31, and ensure that the spring can be stably connected to the second support beam 30.

[0056] In some embodiments, the connecting part 31 further comprises a reinforcing rib 313, one end of the reinforcing rib 313 is connected to the first plate body 311, and the other end is connected to the second plate body 312.

[0057] It can be understood that the reinforcing rib 313 can effectively share stress and avoid excessive deformation or damage of the plate due to excessive stress. The reinforcing rib 313 can greatly improve the bending stiffness and compressive strength of the overall structure. In the present application, the reinforcing rib 313 can be connected to both ends of the first plate body 311 and the second plate body 312, forming a triangular structure, one straight side of the triangular structure is connected to the first plate body 311, and the other straight side is connected to the second plate body 312. When bearing the pressure of the battery pack 200, the triangular reinforcing rib 313 can change the stress distribution, so that the stress of the structure is more uniform.

[0058] In some embodiments, each second support beam 30 is provided with a first positioning hole, and the second end is correspondingly provided with a second positioning hole, and the first positioning hole and the second positioning hole are used to install a positioning pin 300. In the first state, the positioning pin 300 is inserted between one first positioning hole and one second positioning hole, so that the support 10 is fixed to the second support beam 30, and in the second state, the positioning pin 300 is separated from the support 100.

[0059] Specifically, when the support 10 and the battery pack 200 are rotated to the second support beam 30, the support 10 is obliquely arranged between the first support beam 20 and the second support beam 30, at this time the battery pack 200 is obliquely placed and assembled in the support beam, and the positioning pin 300 is correspondingly inserted through the first positioning hole and the second positioning hole to fix the support 10. According to the characteristics of the moment, the force on the second end of the support 10 is smaller than the force on the first end, and when the positioning pin 300 is removed, when the second support beam 30 is located on the left side of the first support beam 20, the support 10 will rotate in the counterclockwise direction and contact the elastic member 40.

[0060] The related art directly pushes the battery pack 200 along the support 100 in the horizontal direction, but the weight of the battery pack 200 is large, so the friction force generated between the battery pack 200 and the battery support 100 is also large, and it is not convenient to enter the box in the horizontal direction during integration. It can be understood that when the support 10 forms a fixed angle, the battery pack 200 can move along the support 10 under the action of gravity to reduce the friction force between the battery pack 200 and the battery support 100. It is better to facilitate the assembly of the battery pack 200.

[0061] The positioning pin 300 can be partially separated from the support 100 or completely separated from the support 100. When it is necessary to fix the battery pack support 10 again, the positioning pin 300 can be partially separated from the support 100, which facilitates subsequent re-fixing and installation. The present application does not limit this.

[0062] The positioning pin 300 can stably fix the support 10 and the second support beam 30 together to prevent relative movement between the second support beam 30 and the support 10 during the process. Ensure the stability of the connection to prevent the battery pack 200 from suddenly moving relative to the support 10. In addition, the positioning pin 300 can also help the operator to conveniently disassemble and install parts, so that the fixing and separation of the support 10 and the second support beam 30 are more convenient. Through the guidance and fixation of the positioning pin 300, it is not necessary to rely too much on manual alignment during assembly, and the operation can be quickly and accurately completed.

[0063] Please refer to Figure 3 , Figure 3 is a structural diagram of the support provided by the embodiments of the present application Figure 2In some embodiments, the support 10 is provided with a limiting part 101, which is arranged at the first end and used to limit the sliding of the battery pack 200 from the second end to the first end out of the support 10.

[0064] Specifically, the support 10 comprises a side wall and a bottom wall connected with each other, the limiting part 101 comprises two side edges connected vertically, the limiting part 101 is arranged at the first end, one side edge is connected to the side wall, and the other side edge is connected to the bottom wall, thereby forming a limiting effect on at least three sides of the battery pack 200. When the battery pack 200 enters from the second end, the limiting part 101 can limit the battery pack 200 from being separated from the first end.

[0065] In some embodiments, in the second state, the second end is higher than the first end.

[0066] It can be understood that if the elastic member 40 is installed at a lower position, so that the second end is lower than the first end, the battery pack 200 can slide from the second end during the rotation without the limiting structure at the second end. The elastic member 40 can be installed at a position slightly higher than the first end, so that the height of the second end after compression of the elastic member 40 is higher than the height of the first end, so that the battery pack 200 cannot be separated from the support 10 under the limitation of the limiting part 101.

[0067] Please refer to Figures 4-5 , Figure 4 is a side view of the support provided by the embodiments of the present application, Figure 5 is an exploded view of the support provided by the embodiments of the present application. In some embodiments, the number of first support beams 20 is two, the support 100 further comprises a rotating shaft 50, the two first support beams 20 are arranged at intervals, and the rotating shaft 50 is rotatably connected with the two first support beams 20. Among them, the number of supports 10 is two, each support 10 is arranged corresponding to one first support beam 20, and the rotating shaft 50 is rotatably connected with the two supports 10, so that the first end of each support 10 can rotate around the rotating shaft 50.

[0068] In some examples, each support 10 is provided with a first mounting hole, each first support beam 20 is provided with a second mounting hole, and the rotating shaft 50 is correspondingly arranged in the first mounting hole and the second mounting hole, so that the first support beam 20 and the first support 10 are rotatably connected. The rotation of the rotating shaft 50 can adjust the inclination angle of the support 10, so that the battery pack 200 can be smoothly pushed into the support 10.

[0069] In some examples, when the rotating shaft 50 is long, only one rotating shaft 50 can be arranged between the two opposite support members 10 along the width direction of the battery pack 200; when the rotating shaft 50 is short, two rotating shafts 50 can be arranged in the first mounting hole and the second mounting hole respectively, so that the support member 10 can be rotated to any angle by mounting the rotating shaft 50, and the battery pack 200 is facilitated to enter the support member 10.

[0070] In some embodiments, each support member 10 is connected between a first support beam 20 and a second support beam 30, and each support member 10 is provided with a sliding groove 102, and the battery pack 200 comprises a bottom plate 201 installed in the sliding groove 102.

[0071] Specifically, when the support member 10 is in the first state, the bottom plate 201 of the battery pack 200 is located in the sliding groove 102, so that the battery pack 200 is inclined to enter the support member 10. The side wall of the support member 10 is used to be connected to the first support beam 20 and the second support beam 30, and the bottom plate 201 is fixed to the bottom wall of the support member 10 after entering the sliding groove 102, for example, by screwing, and when the support member 10 is rotated to the second state, the battery pack 200 can be kept in a relatively fixed position.

[0072] In some examples, the bottom plate 201 comprises a protruding portion 2012 close to the second end and connected to the two sides of the bottom plate 201 respectively, each protruding portion 2012 protrudes away from the other protruding portion 2012, so that the overall width of the battery pack 200 is greater than the distance between the two second support beams 30, and each protruding portion 2012 abuts against one second support beam 30 to limit the battery pack 200 from sliding to the first end.

[0073] The above describes the embodiments of the present application in detail, and the principles and implementation manners of the present application are described by applying specific examples; the above description of the embodiments is only used to help understand the method of the present application and its core idea; meanwhile, for those skilled in the art, according to the idea of the present application, the specific implementation manner and application range can be changed, and the above description of the present application should not be understood as a limitation.
