[0044] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0045] In the present disclosure, unless otherwise stated, directional terms such as the first direction refers to a direction perpendicular to the first conductive member and the second conductive member, and the second direction refers to a direction parallel to the first conductive member and the second conductive member. The first direction and the second direction are both horizontal directions. Figure 1 and Figure 2 "Inside" and "outside" refer to the inside and outside of the relevant parts. In addition, the terms "first" and "second" are only used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0046] It should also be noted that, in the description of this disclosure, unless otherwise expressly specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they may refer to a fixed connection, a detachable connection, or an integral connection. They may be directly connected or indirectly connected through an intermediate medium, or they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this disclosure based on specific circumstances.

[0047] An energy storage device generally has multiple energy storage units, which are stacked so as not to occupy too much lateral space. The energy storage units stacked up and down need to be electrically connected to each other to achieve grounding.

[0048] In the related art, the conductive connection structure between two adjacent energy storage units of the energy storage device is prone to assembly gaps, resulting in poor electrical conduction stability, which may make it impossible to ground or affect the use of the energy storage device.

[0049] For this reason, Figures 1-6 As shown, one aspect of the present disclosure provides a conductive connection component, including a first conductive member 1 and a second conductive member 2 .

[0050] The first conductive member 1 is used to connect to the first energy storage unit 6. The second conductive member 2 is used to connect to the second energy storage unit 7. The first conductive member 1 is electrically connected to the first energy storage unit 6, and the second conductive member 2 is electrically connected to the second energy storage unit 7.

[0051] Among them, the first conductive member 1 and the second conductive member 2 are at least partially contacted and connected to make the first energy storage unit 6 and the second energy storage unit 7 electrically conductive, and a contact portion 3 is formed on at least one of the first conductive member 1 and the second conductive member 2, and the contact portion 3 is clamped between the first conductive member 1 and the second conductive member 2.

[0052] In the above technical solution, by connecting the first conductive member 1 and the second conductive member 2, the first conductive member 1 and the second conductive member 2 can achieve electrical conduction, thereby achieving electrical conduction between the first energy storage unit 6 and the second energy storage unit 7, and realizing a grounding setting in which the first energy storage unit 6 and the second energy storage unit 7 are connected to each other. Of course, the first energy storage unit 6 and the second energy storage unit 7 can also be connected in series or in parallel as needed. By providing a contact portion 3, the contact portion 3 is clamped between the first conductive member 1 and the second conductive member 2, thereby generating a squeezing effect, and the contact portion 3 achieves contact connection between the first conductive member 1 and the second conductive member 2, which can offset the assembly gap between the first conductive member 1 and the second conductive member 2, thereby improving the connection stability and reliability of the first conductive member 1 and the second conductive member 2, and making the electrical conduction between the first energy storage unit 6 and the second energy storage unit 7 stable.

[0053] Optionally, in one embodiment of the present disclosure, the first conductive member 1 and the second conductive member 2 are partially in contact and connected, and the contact portion 3 is located at a position where the first conductive member 1 and the second conductive member 2 contact each other.

[0054] Optionally, in another embodiment of the present disclosure, the first conductive member 1 and the second conductive member 2 are all in contact and connected, and the contact portion 3 is located at a position where the first conductive member 1 and the second conductive member 2 are in contact with each other.

[0055] Optionally, in one embodiment of the present disclosure, the contact portion 3 is configured as a convex portion, extending in a direction relative to the first conductive member 1 and the second conductive member 2 and protruding from the first conductive member 1 and / or the second conductive member 2, so that the contact portion 3 can push the first conductive member 1 and / or the second conductive member 2. By configuring the contact portion 3 as a convex portion, it is facilitated to push the first conductive member 1 and / or the second conductive member 2, thereby allowing the first conductive member 1 and the second conductive member 2 to produce a slight deformation, thereby achieving a tight connection between the first conductive member 1 and the second conductive member 2 through the contact portion 3, and avoiding the presence of a gap between the first conductive member 1 and the second conductive member 2, which would affect the stability of the connection between the two.

[0056] It can be understood that when the first energy storage unit 6 and the second energy storage unit 7 are connected to each other, the first conductive member 1 and the second conductive member 2 are arranged relative to each other and can generate contact. At this time, the contact portion 3 is located between the first conductive member 1 and the second conductive member 2. Due to the contact between the first conductive member 1 and the second conductive member 2, the gap between the first conductive member 1 and the second conductive member 2 is small. At this time, the contact portion 3 will generate a push between the two, thereby connecting the first conductive member 1 and the second conductive member 2 through the contact portion 3 to ensure the connection state. In some examples, the relative direction of the first conductive member 1 and the second conductive member 2 can be set to a first direction, and the first direction is as follows: Figure 2 As shown, it can be set to be perpendicular to the direction of the first conductive member 1 and the second conductive member 2.

[0057] Optionally, in one embodiment of the present disclosure, the contact portion 3 is configured as a bump 32 or a corrugated strip 33 formed on the first conductive member 1 and / or the second conductive member 2. By so configuring, the bump 32 and the corrugated strip 33 can be easily manufactured and processed, with low manufacturing cost.

[0058] In some examples, the protrusions 32 or the corrugated strips 33 can be formed by directly protruding outward from the first conductive part 1 and / or the second conductive part 2, and can be manufactured by a press molding method. The protrusions 32 or the corrugated strips 33 are small in size and can produce a squeezing effect on the first conductive part 1 and / or the second conductive part 2 without occupying too much space on the first conductive part 1 and / or the second conductive part 2.

[0059] Optionally, in another embodiment of the present disclosure, the contact portion 3 includes a telescopic head 34 and a tube body 35. The first end of the tube body 35 is connected to the first conductive member 1 and / or the second conductive member 2, and the second end of the tube body 35 is configured to be open. The telescopic head 34 is slidably connected to the tube body 35 via the second end of the tube body 35. The telescopic head 34 partially protrudes from the tube body 35 and can extend or retract in directions relative to the first conductive member 1 and the second conductive member 2. The end of the telescopic head 34 that extends from the tube body 35 is used to push the first conductive member 1 and / or the second conductive member 2. This configuration can enhance the pushing effect between the first conductive member 1 and / or the second conductive member 2, further improving the connection stability between the first conductive member 1 and / or the second conductive member 2.

[0060] The tube body 35 is hollow, and its interior is used to accommodate the telescopic head 34, allowing it to retract into the tube body 35, thereby enabling the telescopic head 34 to be extended or retracted. The second end of the tube body 35 is open, and thus the telescopic head 34 is connected to the interior of the tube body 35 via the second end of the tube body 35. The telescopic head 34 can extend from the tube body 35 through the second end of the tube body 35, and can also be retracted into the tube body 35 through the second end of the tube body 35. It will be understood that when the telescopic head 34 is retracted into the tube body 35, the telescopic head 34 can be completely retracted into the tube body 35, or it can partially protrude from the telescopic head 34. In its natural state, the telescopic head 34 partially protrudes from the telescopic head 34. When the first conductive member 1 and the second conductive member 2 come into contact with each other, the telescopic head 34 can retract by contacting the first conductive member 1 or the second conductive member 2, thereby exerting a pushing effect on the first conductive member 1 or the second conductive member 2.

[0061] The tube body 35 can guide the expansion and contraction of the expansion head 34 , so that the expansion head 34 can expand and contract along the length direction of the tube body 35 .

[0062] Optionally, in one embodiment of the present disclosure, the contact portion 3 further includes an elastic member 36, which is disposed within the tube 35. The telescopic head 34 is connected to the elastic member 36, and the elastic member 36 is configured to drive the telescopic head 34 out of the tube 35. The elastic member 36 can drive the telescopic head 34 out of the tube 35, thereby generating a pushing effect on the first conductive member 1 and / or the second conductive member 2.

[0063] The elastic member 36 is located within the tube 35. The end of the elastic member 36 away from the expansion joint 34 can be connected to the inner wall of the tube 35. The elastic member 36 can be compressed and rebounded. In some examples, the elastic member 36 is a spring, with one end connected to the expansion joint 34 and the other end connected to the inner wall of the tube 35. In other examples, the elastic member 36 can be a highly elastic metal sheet or organic material.

[0064] It can be understood that when the telescopic head 34 is squeezed back into the tube body 35 by external force, the elastic member 36 is subjected to the squeezing force and is in a compressed state. When the telescopic head 34 is not squeezed by external force, the elastic member 36 is reset and can push the telescopic head 34 out of the tube body 35.

[0065] Optionally, in another embodiment of the present disclosure, the tube body 35 can be filled with air, and the end of the telescopic head 34 extending into the tube body 35 can be sealed and connected to the inner wall of the tube body 35. When the telescopic head 34 is retracted into the tube body 35, it can compress the air in the tube body 35, thereby allowing the telescopic head 34 to produce a pushing effect on the first conductive member 1 or the second conductive member 2.

[0066] In order to prevent the telescopic head 34 from being separated from the tube body 35 and becoming unusable, optionally, in one embodiment of the present disclosure, the contact portion 3 further includes an elastic circlip 37, which is disposed within the tube body 35 and close to the second end of the tube body 35. The inner wall of the second end of the tube body 35 is provided with a receiving groove 39, and the elastic circlip 37 is connected to the receiving groove 39. The elastic circlip 37 can prevent the telescopic head 34 from being separated from the tube body 35. The provision of the elastic circlip 37 can prevent the telescopic head 34 from completely extending from the tube body 35, thereby preventing the telescopic head 34 from being separated from the tube body 35. The elastic circlip 37 is elastic and can avoid rigid collision, thereby achieving good use effect.

[0067] The circlip 37 is annular and is sleeved on the telescopic head 34. The receiving groove 39 is annular and the circlip 37 is disposed within the receiving groove 39 to secure the circlip 37. The telescopic head 34 is located within the tube 35 and near one end of the elastic member 36. An annular contact portion 3 that cooperates with the circlip 37 may be formed. When the elastic member 36 is reset and pushes the telescopic head 34 out of the tube 35, the annular contact portion 3 may contact the circlip 37 as the telescopic head 34 moves, thereby limiting the position and preventing the telescopic head 34 from completely extending out of the tube 35. In some examples, the circlip 37 may be made of rubber.

[0068] To facilitate connection of the tube body 35 to the first conductive member 1 and / or the second conductive member 2, optionally, in one embodiment of the present disclosure, a rivet root 38 is provided at the first end of the tube body 35. The rivet root 38 is riveted to the first conductive member 1 and / or the second conductive member 2. The rivet root 38 allows for direct riveting to the first conductive member 1 and / or the second conductive member 2, which is very convenient to operate and provides a secure connection.

[0069] Optionally, in another embodiment of the present disclosure, the first end of the tube body 35 may be welded to the first conductive member 1 and / or the second conductive member 2 .

[0070] In order to further improve the reliability of the connection between the first conductive member 1 and the second conductive member 2, optionally, in one embodiment of the present disclosure, there are multiple contact portions 3, and the multiple contact portions 3 are spaced apart in a direction parallel to the first conductive member 1 and the second conductive member 2. Through the multiple contact portions 3, different positions of the first conductive member 1 and / or the second conductive member 2 can be pushed respectively, so that the gaps between the first conductive member 1 and the second conductive member 2 at different positions can be connected through the contact portions 3, thereby ensuring the stability and reliability of electrical conduction. In some examples, the direction parallel to the first conductive member 1 and the second conductive member 2 can be set to the second direction, specifically as Figure 1 shown.

[0071] Optionally, in one embodiment of the present disclosure, the first conductive member 1 has a first connecting surface, the second conductive member 2 has a second connecting surface, the first connecting surface and the second connecting surface are arranged opposite to each other, the first connecting surface and the second connecting surface are in at least partial surface-to-surface contact, and a contact portion 3 is formed on at least one of the first connecting surface and the second connecting surface.

[0072] Among them, the contact part 3 and the first conductive part 1 and / or the second conductive part 2 can be integrally formed, and the first conductive part 1 and / or the second conductive part 2 can be elastically deformed under the pushing action of the contact part 3 to form a stable contact force to ensure the connection stability of the first conductive part 1 and the second conductive part 2.

[0073] Among them, the first connection surface of the first conductive part 1 and the second connection surface of the second conductive part 2 are in surface-to-surface contact, which can increase the connection area, facilitate the connection between the first conductive part 1 and the second conductive part 2, and make the arrangement of the first conductive part 1 and the second conductive part 2 or the first energy storage unit 6 and the second energy storage unit 7 more flexible. By setting the contact portion 3, the first connection surface and the second connection surface can be pushed to ensure the connection state of the two, and the stability and reliability of the electrical conduction can be ensured. In some examples, the first conductive part 1 and the second conductive part 2 can both be metal sheets. In other examples, the first conductive part 1 and the second conductive part 2 can also be metal blocks. Among them, in some examples, the first conductive part 1 and the second conductive part 2 both extend along the second direction.

[0074] Optionally, in one embodiment of the present disclosure, a contact portion 3 is formed on the first connection surface, and the contact portion 3 is used to push the second conductive member 2. This configuration can save manufacturing costs, and providing the contact portion 3 on the first connection surface can ensure connection reliability between the first conductive member 1 and the second conductive member 2.

[0075] Optionally, in one embodiment of the present disclosure, a contact portion 3 is formed on the second connection surface, and the contact portion 3 is used to push the first conductive member 1. This configuration can save manufacturing costs, and providing the contact portion 3 on the second connection surface can ensure connection reliability between the first conductive member 1 and the second conductive member 2.

[0076] Optionally, in one embodiment of the present disclosure, contact portions 3 are formed on both the first connection surface and the second connection surface, and the contact portions 3 are used to respectively push the first conductive member 1 and the second conductive member 2. By so doing, the connection reliability of the first conductive member 1 and the second conductive member 2 can be better achieved.

[0077] In order to achieve the limitation of the relative movement of the first energy storage unit 6 and the second energy storage unit 7 in the horizontal and vertical directions, optionally, in one embodiment of the present disclosure, the conductive connection component further includes a locking mechanism 4, which is connected to the first conductive member 1 and the second conductive member 2, and the locking mechanism 4 locks the first conductive member 1 and the second conductive member 2 in a direction perpendicular to the first conductive member 1 and the second conductive member 2. The direction perpendicular to the first conductive member 1 and the second conductive member 2 can be set as the first direction, see Figure 2 shown.

[0078] The locking mechanism 4 can fix the first conductive member 1 and the second conductive member 2 again after they are pushed and connected together by the contact portion 3, thereby preventing the first conductive member 1 and the second conductive member 2 from moving in the first direction and the vertical direction, thereby improving the connection stability of the first energy storage unit 6 and the second energy storage unit 7. At the same time, the locking mechanism 4 can make the first conductive member 1 and the second conductive member 2 move closer to each other. Under the pushing action of the contact portion 3, the connection between the second conductive member 2 and the contact portion 3 is tighter, thereby improving the electrical conduction stability.

[0079] Optionally, in one embodiment of the present disclosure, the locking mechanism 4 includes a locking bolt 41 and a nut 42 , and through holes are provided on the first conductive member 1 and the second conductive member 2 and are interconnected, and the locking bolt 41 passes through the through holes and is connected to the nut 42 .

[0080] Among them, the locking bolt 41 can pass through the through holes on the first conductive member 1 and the second conductive member 2, and then cooperate with the nut 42 to lock the first conductive member 1 and the second conductive member 2. The operation is very convenient and the locking effect is firm.

[0081] Optionally, in another embodiment of the present disclosure, the locking mechanism 4 includes a clamping buckle, which is clamped to the first conductive member 1 and the second conductive member 2, and the first conductive member 1 and the second conductive member 2 are locked by the clamping buckle.

[0082] A second aspect of the present disclosure further provides an energy storage device, comprising a first energy storage unit 6 , a second energy storage unit 7 and the above-mentioned conductive connection component.

[0083] The first energy storage unit 6 and the second energy storage unit 7 are stacked, the first conductive member 1 of the conductive connection component is connected to the first energy storage unit 6 , and the second conductive member 2 of the conductive connection component is connected to the second energy storage unit 7 .

[0084] The first energy storage unit 6 and the second energy storage unit 7 can be battery packs. The first energy storage unit 6 and the second energy storage unit 7 are electrically connected via a conductive connection component, which can achieve grounding and other related electrical connection requirements. In some examples, the first energy storage unit 6 is stacked on the second energy storage unit 7.

[0085] Optionally, in one embodiment of the present disclosure, a first limiting portion 8 is provided at the bottom of the first energy storage unit 6 and the bottom of the second energy storage unit 7, and a second limiting portion 9 is provided at the top of the first energy storage unit 6 and the top of the second energy storage unit 7, and the first limiting portion 8 and the second limiting portion 9 are configured to cooperate with each other.

[0086] The first limiting portion 8 of the first energy storage unit 6 and the second limiting portion 9 of the second energy storage unit 7 cooperate to limit the relative parallel movement of the first energy storage unit 6 and the second energy storage unit 7. This arrangement ensures that the first energy storage unit 6 and the second energy storage unit 7 remain stable when stacked, preventing them from tilting or falling. It should be noted that relative parallel movement refers to the movement of the first energy storage unit 6 and the second energy storage unit 7 on the same plane, preventing misalignment between the first energy storage unit 6 and the second energy storage unit 7.

[0087] Among them, the number of the first energy storage unit 6 and the second energy storage unit 7 is not limited, and they can be stacked according to actual needs. That is, the first energy storage unit 6 is stacked on top of the second energy storage unit 7, and another second energy storage unit 7 can be stacked on top of the first energy storage unit 6. And so on, a plurality of first energy storage units 6 and second energy storage units 7 can be stacked. In some examples, one of the first limiting portion 8 and the second limiting portion 9 can be set as a groove, and the other can be set as a convex hull, which can be snapped into the groove. In other examples, the first limiting portion 8 and the second limiting portion 9 can be light holes, and positioning is achieved by passing a positioning pin through the light hole.

[0088] In order to avoid the problem of rust on the locking mechanism 4, optionally, in one embodiment of the present disclosure, the conductive connection component further includes a sealing plug 51 and a cover 5, the cover 5 is used to be connected to the first conductive member 1 or the second conductive member 2, the cover 5 covers the locking mechanism 4, an operation hole is provided on the cover 5, the operation hole faces the locking mechanism 4, and the sealing plug 51 is detachably connected to the operation hole. The provided cover 5 can cover and protect the locking mechanism 4 to prevent the locking mechanism 4 from being affected by external moisture and rusting, and the provided operation hole can facilitate the user to operate the locking mechanism 4, so that the locking mechanism 4 can lock or unlock the first conductive member 1 and the second conductive member 2.

[0089] The sealing plug 51 is used to seal the operating hole, ensuring that the locking mechanism 4 is covered and protected. It will be understood that when the locking mechanism 4 needs to be operated, the sealing plug 51 is removed from the operating hole, allowing the user to operate the locking mechanism 4 through the operating hole. When the locking mechanism 4 is no longer needed, the sealing plug 51 is inserted back into the operating hole to provide a covering and protection for the locking mechanism 4.
