The embodiment of the application provides a battery 10, where the battery 10 can store electric energy, and under the condition of accessing electric equipment, the battery 10 can provide electric energy for the electric equipment so as to realize the function of the electric equipment.

Referring to fig. 1 and 2, in the present embodiment, the battery 10 includes an end plate 100, an output electrode (not shown), and a support 200. Wherein the supporting member 200 is inserted into the end plate 100, and the output electrode is disposed on the supporting member 200; the end plate 100 may provide a bearing to the support 200 and the support 200 may provide a bearing to the output pole. It should be noted that the supporting member 200 can solve the technical problem of low production efficiency caused by high difficulty in assembling the supporting member in the prior art. Based on this, the battery 10 employing the support 200 can solve the technical problem of low production efficiency caused by high difficulty in assembling the support in the prior art.

It should be noted that, the battery 10 may further include a battery cell, a battery management system, etc. to implement the functions of the battery 10, and the other structures described above are related art and are not described herein again.

In the present embodiment, referring to fig. 2, 3 and 4 in combination, the support 200 includes a support body 210, a slider 220 and an elastic member 230. The support body 210 includes a support portion 211 and a socket portion 212, the socket portion 212 being configured to be fitted to the end plate 100 such that at least a portion of the support portion 211 is exposed to a top surface of the end plate 100, the top surface representing a side surface of the end plate 100 in a height direction; the supporting portion 211 is used for carrying the output electrode. The slider 220 is movably connected to the plug portion 212, the slider 220 extends out of the plug portion 212 and is used for being matched with the end plate 100, and the slider 220 is also used for moving relative to the plug portion 212 to retract the plug portion 212 and release the matching with the end plate 100. The elastic member 230 is disposed inside the plugging portion 212, at least a portion of the elastic member 230 is disposed on a moving path of the slider 220, and the slider 220 drives the elastic member 230 to elastically deform when the slider 220 is retracted into the plugging portion 212.

In the above-mentioned manner, in the case where the support member 200 is required to be assembled to the end plate 100 of the battery 10, the sliding block 220 may be retracted into the insertion portion 212 under the action of external force, and in the process of inserting the insertion portion 212 into the end plate 100, the limiting effect may be provided to the sliding block 220 by the end plate 100, so that the sliding block 220 is ensured to be positioned inside the insertion portion 212, and the insertion portion 212 is convenient to be continuously inserted into the end plate 100. After the insertion portion 212 is inserted into the end plate 100, the external force of the slider 220 is removed, and the slider 220 extends out of the insertion portion 212 under the restoring action of the elastic member 230, so that the support member 200 and the end plate 100 can be assembled by the cooperation of the slider 220 and the end plate 100. The assembly mode of the supporting piece 200 is simple, the difficulty in assembling the supporting piece 200 to the end plate 100 is reduced, the assembly efficiency of the supporting piece 200 can be improved, and the production efficiency is improved. Based on this, the support 200 and the battery 10 employing the support 200 can improve the technical problem of low production efficiency due to difficulty in assembling the support in the prior art.

Alternatively, in the present embodiment, the support 200 includes two sliders 220 and two elastic members 230. In the case of the two sliders 220 in the extended state, the two sliders 220 extend from opposite sides of the insertion portion 212, respectively; the two elastic members 230 are disposed inside the plugging portion 212, and the two elastic members 230 are disposed on the moving paths of the two sliding blocks 220 respectively.

In the case where both the slider 220 extend out of the insertion portion 212, a restraining effect can be provided to the insertion portion 212 from opposite sides of the insertion portion 212 by the two slider 220, so that the stability of the insertion portion 212 in the end plate 100 can be improved.

It should be appreciated that in other embodiments of the present application, the number of the sliding blocks 220 and the elastic members 230 may be adjusted according to actual situations, for example, in case that the space inside the end plate 100 is insufficient, only one elastic member 230 and one sliding block 220 may be provided. Of course, to improve the stability of the plug portion 212, the number of the slider 220 and the elastic member 230 may be increased.

In the present embodiment, the insertion portion 212 is provided with an accommodating space 2121 inside; the side wall of the plug-in part 212 is provided with a matching hole 2122 communicated with the accommodating space 2121; the slider 220 is movably fitted to the fitting hole 2122. That is, the slider 220 may slide in the fitting hole 2122 to extend the insertion portion 212 or retract the insertion portion 212.

It should be noted that, in order to ensure that the slider 220 moves along a predetermined path, the shape of the engagement hole 2122 is adapted to the cross-sectional shape of the slider 220, so that a restraining effect can be provided to the slider 220 to prevent the slider 220 from deflecting to cause the movement path of the slider 220 to deviate. It should be appreciated that the mating hole 2122 has a slightly larger aperture size than the cross-sectional area of the slider 220 to facilitate sliding of the slider 220 within the mating hole 2122.

In addition, in the present embodiment, the elastic member 230 is in a sheet shape, and one side of the elastic member 230 is connected to the inner wall of the accommodating space 2121, and the other side extends to the moving path of the slider 220. Generally, one end of the elastic member 230 is coupled to the inner circumferential wall of the receiving space 2121, and the moving path of the slider 220 corresponds to the other end of the elastic member 230, thereby facilitating the forced deformation of the elastic member 230.

It should be understood that in other embodiments of the present application, the elastic member 230 may be provided in other forms. For example, the elastic member 230 is provided as a spring sleeved on the slider 220. Of course, in the case where the elastic member 230 is provided as a spring, a fixing structure against which the spring is held is provided in the accommodation space 2121; correspondingly, a protruding structure for the elastic member 230 to abut against is further provided on the slider 220.

Further, the extending direction of the elastic member 230 is disposed at an angle to the moving direction of the slider 220. Therefore, when the slider 220 is retracted into the insertion portion 212 and abuts against the elastic member 230, the elastic member 230 can be easily deformed, so that the slider 220 is conveniently retracted, and the assembly difficulty is reduced.

Preferably, in the present embodiment, the moving path of the slider 220 is perpendicular to the elastic member 230, so that when the slider 220 abuts against the elastic member 230, the force applied by the slider 220 to the elastic member 230 is perpendicular to the elastic member 230, so that the elastic member 230 can be easily urged to elastically deform, which facilitates the retraction of the slider 220 and reduces the assembly difficulty.

Of course, in other embodiments of the present application, an acute angle, an obtuse angle, or the like may be formed between the moving path of the slider 220 and the elastic member 230.

To facilitate assembly of the support 200, in this embodiment, the portion of the slider 220 extending beyond the insertion portion 212 is provided with a guiding surface 221, and the guiding surface 221 is used to abut against the end plate 100 during insertion of the insertion portion 212 into the end plate 100, so that the end plate 100 applies a force for retracting the insertion portion 212 to the slider 220.

That is, when the support 200 is assembled, the support 200 may be directly inserted into the end plate 100, and during the insertion process, the guide surface 221 of the slider 220 abuts against the end plate 100, and since the guide surface 221 is inclined, the force for retracting the insertion portion 212 may be applied to the slider 220 by the abutment of the end plate 100, so as to prompt the slider 220 to retract into the insertion portion 212; after the insertion portion 212 is inserted into the end plate 100, the slider 220 is released from the end plate 100, and is then released by the elastic restoring action of the elastic member 230, so as to assemble the slider 220 with the end plate 100.

Optionally, the guiding surface 221 is curved. Wherein the guiding surface 221 presents a convex arc-shaped surface. It should be appreciated that in other embodiments of the present application, the guide surface 221 may also be presented as an inclined plane.

In this embodiment, referring to fig. 4, 5, 6 and 9, the slider 220 has a first end 201 and a second end 202 opposite to each other, and the first end 201 extends out of the plugging portion 212; that is, the guiding surface 221 is disposed at the first end 201, and the second end 202 is for abutting against the elastic member 230. The support 200 further includes a detachment structure 222, the detachment structure 222 being disposed at the second end 202; the dismounting structure 222 is provided with a driving part 2221 in a protruding manner; the plugging portion 212 is provided with a disassembly hole 2123, the disassembly hole 2123 is used for allowing the disassembly piece 300 to extend into so that the disassembly piece 300 is matched with the driving portion 2221, and the disassembly piece 300 is used for driving the driving portion 2221 to move so that the driving portion 2221 drives the sliding block 220 to retract into the plugging portion 212.

That is, in the case that the support 200 needs to be disassembled, only the disassembling piece 300 needs to be extended into the plugging portion 212 from the disassembling hole 2123, so that the disassembling piece 300 is matched with the driving portion 2221, and the driving portion 2221 drives the slider 220 to retract into the plugging portion 212 under the driving of the disassembling piece 300. After the slider 220 is retracted into the insertion portion 212, the engagement between the slider 220 and the end plate 100 is released, and the support 200 is directly pulled out to complete the detachment of the support 200. The difficulty in disassembly of the support 200 can be reduced, and the maintenance cost of the battery 10 can be reduced.

Alternatively, in the present embodiment, the driving part 2221 is spaced apart from the second end 202. In the case that the dismounting member 300 extends into the inserting portion 212 to be matched with the driving portion 2221, the dismounting member 300 is located between the driving portion 2221 and the second end 202, and therefore, when the dismounting member 300 applies a force to a side of the driving portion 2221, which is close to the second end 202, the driving portion 2221 is driven to drive the slider 220 to retract into the inserting portion 212.

In the present embodiment, in the case where the support 200 includes two oppositely disposed sliders 220, the detaching formations 222 on the two sliders 220 are staggered, and the driving portion 2221 on one slider 220 is made to correspond to between the other slider 220 and the other driving portion 2221; two driving portions 2221 are arranged at intervals; the dismounting hole 2123 corresponds to between the two driving portions 2221. The dismounting member 300 is configured to extend between the two driving portions 2221, and the dismounting member 300 is further configured to increase or decrease the width of the portion of the dismounting member 300 located between the two driving portions 2221 when the dismounting member 300 is movable relative to the plug portion 212.

It should be noted that, the staggered arrangement of the dismounting structures 222 on the two sliders 220 may also be regarded as that the two dismounting structures 222 are staggered, that is, the two dismounting structures 222 are not overlapped in the moving direction of the two sliders 220, so as to avoid the situation that the two dismounting structures 222 affect each other to cause the sliders 200 to move out of place.

Based on this, in the case that the dismounting member 300 is inserted into the insertion portion 212, the insertion member can be located between the two driving portions 2221, and at this time, in the case that the width of the dismounting member 300 between the driving portions 2221 is increased, the two driving portions 2221 can be simultaneously driven to drive the two sliding blocks 220 to retract into the insertion portion 212, thereby facilitating the dismounting of the supporting member 200.

Alternatively, for the selection of the disassembly 300, a flat-shaped part may be selected, the disassembly 300 is vertically inserted between the two driving parts 2221, however, the disassembly 300 is rotated such that the disassembly 300 is turned over by 90 °, the width of the disassembly 300 between the two driving parts 2221 may be increased, and thus the two driving parts 2221 may be driven such that the two sliders 220 are retracted inside the insertion part 212. Of course, in other embodiments, the disassembly 300 may alternatively be configured like scissors, wherein the two drives 2221 are moved by expanding the disassembly 300 after extending into the disassembly 300 to retract the two slides 220.

Alternatively, the dismounting structure 222 and the driving portion 2221 together form an L-shape. It should be appreciated that in other embodiments of the present application, the detachment structure 222 and the driving portion 2221 may also be commonly provided in other shapes, such as a T-shape, etc.

In this embodiment, referring to fig. 2 and 7 in combination, the end plate 100 is provided with a mating cavity 101 adapted to the plugging portion 212; the end plate 100 is provided with a first through hole 102, the first through hole 102 is communicated with the matching cavity 101, and at least part of the dismounting hole 2123 is exposed from the first through hole 102 when the plug-in portion 212 is assembled in the matching cavity 101. That is, the dismounting member 300 may extend from the first through hole 102, so that the dismounting member 300 extends into the plugging portion 212, and the dismounting of the supporting member 200 is facilitated.

In this embodiment, the end plate 100 is provided with a reinforcing rib 110, the reinforcing rib 110 is provided with an assembly hole 111, and a portion of the slider 220 extending out of the insertion portion 212 extends into the assembly hole 111. The assembly hole 111 may be formed by eliminating a portion of the reinforcing rib 110 to form a groove in the reinforcing rib 110, the groove penetrating the reinforcing rib 110 in the thickness direction of the reinforcing rib 110, thereby forming the assembly hole 111.

It should be noted that, as shown in fig. 7 and 8, a plurality of reinforcing ribs 110 are provided inside the end plate 100, so that the length of a part of the reinforcing ribs 110 is shortened when the matching cavity 101 is formed, and in the case that the supporting member 200 is inserted into the matching cavity 101, a supporting effect can be provided to the supporting member 200 through the reinforcing ribs 110, thereby improving the stability of the supporting member 200.

Optionally, the end plate 100 is provided with a second through hole 103, and the second through hole 103 penetrates through the outer peripheral wall of the end plate 100 and is communicated with the assembly hole 111. By the arrangement of the second through holes 103, whether the slider 220 is fitted with the fitting hole 111 can be observed from the outside of the end plate 100, thereby judging whether the support 200 is stably fitted with the end plate 100, and it is possible to easily inspect the battery 10 after the completion of the assembly, improving the yield.

In summary, in the case where the support 200 needs to be assembled to the end plate 100 of the battery 10, the sliding block 220 may be retracted into the plugging portion 212 under the action of an external force, and in the process of inserting the plugging portion 212 into the end plate 100, a restraining effect may be provided to the sliding block 220 by the end plate 100, so that the sliding block 220 is located inside the plugging portion 212, and the plugging portion 212 is convenient to be continuously inserted into the end plate 100. After the insertion portion 212 is inserted into the end plate 100, the external force of the slider 220 is removed, and the slider 220 extends out of the insertion portion 212 under the restoring action of the elastic member 230, so that the support member 200 and the end plate 100 can be assembled by the cooperation of the slider 220 and the end plate 100. The assembly mode of the supporting piece 200 is simple, the difficulty in assembling the supporting piece 200 to the end plate 100 is reduced, the assembly efficiency of the supporting piece 200 can be improved, and the production efficiency is improved. Based on this, the support 200 and the battery 10 employing the support 200 can improve the technical problem of low production efficiency due to difficulty in assembling the support in the prior art.

The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the scope of the present utility model should be included in the present utility model.
