[0002] A battery pack usually includes a shell, a battery cell arranged in the shell, a pole ear extending from the battery cell, and a cover plate for buckling on the shell. The cover plate is usually provided with a pole connected to the pole ear. A protective structure, i.e., a spacer, is usually arranged between the battery cell and the cover plate. The spacer is provided with a pole ear channel for the pole ear to pass through.

In order to solve this problem, in the related technology, a connecting structure (such as a buckle) for fixing to the battery pack structure can be provided on the spacer. However, such a design will lead to a complex spacer structure and installation process, and it is inconvenient for the robot arm to grab the spacer when automation is produced.

DETAILED DESCRIPTION

[0042] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0043] In the present disclosure, unless otherwise stated, according to the context, the directional words used, such as "inside, outside", "front, back", etc., may be based on the structure of the relevant parts themselves, or may be based on the orientation of the relevant parts when used in combination. For example: the block is located on the plate surface of the plate segment to separate the plate segment into a "front" baffle plate located on one side of the block and a "rear" baffle plate located on the other side of the block. The "front and back" here are defined based on the installation of the spacer monomer between the battery cell and the cover plate of the battery. The side close to the cover plate is the "front" and the side close to the battery cell is the "rear"; the edge of the "boss" away from the block forms at least one "concave" avoidance gap. The "concave" here refers to being concave in the direction close to the block.

[0044] In the present disclosure, the terms "first", "second", etc. are used to distinguish one element from another element, and do not have order and importance. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0045] In order to facilitate the understanding of the technical solution, the battery structure is first introduced here, refer to Fig. 9 The battery includes a shell 130, a battery cell 110 installed in the shell 130, a tab 111 led out from the battery cell 110, a cover plate 120 buckled on the shell 130, and a spacer assembly installed between the cover plate 120 and the end of the battery cell 110. The cover plate 120 is provided with a pole, and the tab 111 is led out from the battery cell 110 and passes through the spacer assembly to connect to the pole. Specifically, a channel for the tab 111 to pass through can be provided on the spacer assembly, or the tab 111 can be pre-pressed by two spacer monomers as described below. This point will be specifically introduced below and will not be explained too much here. The present disclosure is a related improvement made to the structure of the above-mentioned spacer assembly.

[0046] Reference Figure 1-Figure 9 The present disclosure exemplarily shows a spacer monomer for a battery, including a plate segment 200 and a block 300 connected at an angle to each other, wherein the block 300 is located on the plate surface of the plate segment 200 to separate the plate segment 200 into a front baffle 210 located on one side of the block 300 and a rear baffle 220 located on the other side of the block 300.

[0047] The present disclosure does not limit the shape of the block 300, for example, it can be configured as a plate as described below, or it can also be a block, an irregular shape, etc., as long as it can separate the plate segment 200 into the front baffle 210 and the rear baffle 220. The block 300 can be integrally formed with the plate segment 200, or can also be assembled.

[0048] In the embodiment of the present disclosure, the plate segment 200 and the block 300 may be of equal length, and the block 300 is located in the center of the plate segment 200. Alternatively, in some other embodiments, the plate segment 200 may be longer than the block 300, and the block 300 is located near one side of the plate segment 200.

[0049] By using the above technical solution, during the assembly process of the battery, the two spacer monomers are butt-jointed and assembled into a spacer assembly and installed between the battery cover 120 and the battery cell 110. Fig. 9 , the rear baffles 220 of the two spacer monomers can extend to the outside of the side walls of the battery cell 110 respectively, so that the spacer assembly can clamp the battery cell 110 from three directions (the two side surfaces of the battery cell 110 and the end surface of the battery cell 110 facing the cover plate 120), so that the movement of the spacer assembly can be limited by the battery cell 110, and there is no need to add an additional connection structure (such as a buckle) to the spacer assembly to limit the displacement of the spacer assembly. In addition, a storage space for accommodating the pole ear 111 of the battery cell 110 can be formed between the two front baffles 210 to prevent the pole ear 111 from contacting the battery housing 130 and causing a short circuit. Such a design can simplify the structure of the spacer monomer and reduce the difficulty of the assembly process of the spacer monomer, while achieving a better limiting effect on the spacer monomer, and the simplified spacer monomer has more flat surfaces, which is more conducive to automatic grasping during automated production.

[0050] Reference Figure 1-Figure 9 In the embodiment of the present disclosure, the end of the block 300 away from the plate segment 200 is defined as the abutment end 310, wherein the spacer monomer can be constructed so that when assembled with another spacer monomer, the abutment ends 310 of the two spacer monomers are close to each other to compress the pole ear 111 of the battery. In some embodiments, it can be pressed specifically at the root of the pole ear 111, and the root of the pole ear 111 refers to the part of the pole ear 111 close to the battery cell 110, which is relatively stable relative to the tail or middle part, because it is closer to the battery cell 110, has greater restraint force and stronger anti-bending ability. The pole ear 111 is pre-pressed (interference fit) by the abutment ends 310 of the two spacer monomers, so that the spacer monomer and the pole ear 111 can be formed as a whole, that is, the pole ear 111 can limit the displacement of the spacer monomer, further improving the stability of the spacer assembly. It should be explained that, in the embodiment of the present disclosure, the abutting end 310 refers to a portion used to fit with the tab 111 , for example, it may be an end surface of the block 300 away from the plate segment 200 .

[0051] In the embodiment of the present disclosure, at least the portion of the block 300 that is used to abut against the tab 111 of the battery may be made of an elastic material, such as rubber, etc. With such a design, after the tab 111 is clamped by the two blocks 300, the block 300 is squeezed and deformed by the tab 111, and the deformation can generate elastic force to compress the tab 111, thereby increasing the friction between the tab 111 and the spacer monomer, so that the spacer monomer is not easy to fall off from the tab 111 or to be displaced.

[0052] In order to increase the friction between the abutting end 310 and the tab 111 to prevent the spacer from falling off or shifting from the tab 111, in some embodiments, a friction structure may be formed on the abutting end 310. The friction structure may be a friction texture formed with the abutting end 310, or may be an anti-slip pad attached to the abutting end 310, etc., which is not limited in the present disclosure.

[0053] Reference Figure 1-Figure 8 , Figure 10-11 In the embodiment of the present disclosure, the spacer monomer may further include a first mounting portion 410 disposed at one end of the plate segment 200 and the block 300 in the extension direction, and a second mounting portion 420 disposed at the other end of the plate segment 200 and the block 300 in the extension direction. With such a design, when two spacer monomers are assembled into a spacer assembly, the first mounting portion 410 of one spacer monomer is connected to the second mounting portion 420 of the other spacer monomer, and the second mounting portion 420 of one spacer monomer is connected to the first mounting portion 410 of the other spacer monomer. During the specific installation, the abutting ends 310 of the two spacer monomers are opposite to each other, and the two spacer monomers are arranged in opposite directions in the length direction. When assembling the spacer unit to the battery, the two spacer units can be first arranged at the ends of the battery cell 110, and the pole ear 111 can pass through the middle of the two abutting ends 310, and the two spacer units can be assembled into a spacer assembly through the first mounting portion 410 and the second mounting portion 420. At this time, the pole ear 111 is pressed between the two abutting ends 310.

[0054] The present disclosure does not limit the specific structures of the first mounting portion 410 and the second mounting portion 420. Figure 1-Figure 5 In the illustrated embodiment, the first mounting portion 410 may include a first mounting seat 411 and a buckle 412 located at the first mounting seat 411, and the second mounting portion 420 may include a second mounting seat 421 and a slot 422 located at the second mounting seat 421. The buckle 412 and the slot 422 cooperate to achieve detachable cooperation of the two spacer ring monomers. In the embodiment of the present disclosure, the buckle 412 may be a mushroom buckle, and the slot 422 may be a mushroom buckle hole. In addition, in some other embodiments, the buckle 412 may be a through-nail buckle, an expansion buckle, etc.

[0055] Reference Figure 10-11In the embodiment of the present disclosure, the first surface 413 of the first mounting seat 411 provided with the buckle 412, the second surface 423 of the second mounting seat 421 provided with the slot 422, and the end surface of the abutting end 310 can be flush. With such a design, when the buckle 412 is inserted into the slot 422 and snapped into place (the first surface 413 and the second surface 423 fit each other), at this time, since the end surface of the abutting end 310 is flush with the first surface 413 and the second surface 423, when the buckle 412 is snapped into place, the two abutting ends 310 can fit each other so as to clamp the tab 111 therebetween. In addition, in some other embodiments, the abutting end 310 may also be shorter than the first surface 413 and the second surface 423, so that when the first surface 413 and the second surface 423 are in contact, a gap is left between the two abutting ends 310 for the pole ear 111 to pass through; however, in order to achieve compression of the pole ear 111, the thickness of the gap may be smaller than the thickness of the pole ear 111.

[0056] Reference Figure 1-Figure 8 In the embodiment of the present disclosure, the first mounting seat 411 and the second mounting seat 421 may respectively have a first injection hole 510, one end of the first injection hole 510 is used to face the cover plate 120 of the battery, and the other end is used to face the battery cell 110. It should be explained that the injection hole, that is, the injection channel, is used to fill or adjust the electrolyte level in the battery to maintain the liquid level required for the normal operation of the battery. At the same time, the liquid level hole is also the outlet for the exhaust gas and water vapor when the lead-acid battery is charged. These gases and water vapor will be discharged into the external environment through the liquid level hole, thereby ensuring the safety and stable operation of the battery. By respectively providing the first injection hole 510 on the first mounting seat 411 and the second mounting seat 421, the battery can be injected at the same time. Furthermore, since the present solution does not require additional buckle points for connecting the battery shell to the sides of the first mounting seat 411 and the second mounting seat 421, there is no need to set reinforcing ribs at this position, that is, the flow path of the first injection hole 510 can be entirely used for injection. Compared with the traditional spacer assembly (because buckle points are set at this position, reinforcing ribs need to be set at the injection hole position), such a design will not affect the injection flow rate and improve the injection efficiency.

[0057] Reference Figure 1-Figure 8 In the embodiment of the present disclosure, the block 300 may form a second injection hole 520, one end of the second injection hole 520 is used to face the battery cover 120, and the other end is used to face the battery cell 110. By providing the second injection hole 520 in the block 300, the injection efficiency can be improved. The number of the second injection hole 520 can be multiple.

[0058] It should be noted that, when there is only the first injection hole 510 , in the extension direction of the plate segment 200 and the block 300 , both ends of the battery cell 110 extend at least to the first mounting seat 411 and the second mounting seat 421 to be injected through the first injection hole 510 .

[0059] Reference Figure 1-Figure 5 , Fig. 9 In an embodiment of the present disclosure, a convex edge 610 may be formed at the edge of the front baffle 210 on the side away from the grid 300. The length of the convex edge 610 may be the same as that of the front baffle 210, and the present disclosure does not limit this. During assembly, the spacer unit is first installed to the end of the battery cell 110, and then an insulating film is wrapped around the battery cell 110 and on the outside of the spacer unit to prevent the pole piece of the battery cell 110 from contacting and short-circuiting with the shell 130. The thickness of the convex edge 610 may be greater than or equal to the thickness of the film 140, and the edge position of the film 140 is attached to the outer side of the spacer unit adjacent to the convex edge 610. With such a design, when the battery cell 110, the film 140 and the spacer assembly are extended into the shell 130, the convex edge 610 can prevent the shell 130 from scratching the edge position of the film 140 and causing it to tilt, thereby limiting the position of the diaphragm in the battery. In addition, the convex edge 610 can increase the thickness of the front baffle 210 to reduce the deformation of the spacer unit after assembly. The above advantages make it easier for the battery cell 110 to enter the shell (housing 130).

[0060] The present disclosure does not limit the formation method of the convex edge 610 . For example, in some embodiments, the convex edge 610 may be integrally formed with the front baffle 210 . Alternatively, the convex edge 610 may be attached to the outer edge of the front baffle 210 .

[0061] Reference Figure 1-Figure 5 , Fig. 9 In the embodiment of the present disclosure, a boss 620 may be provided on one side of the front baffle 210 adjacent to the block 300. With such a design, when the cover plate 120 is buckled on the open end of the housing 130, the boss 620 may stop the cover plate 120 to prevent the cover plate 120 from extending too far into the housing 130, thereby ensuring the bending space of the tab 111. At the same time, the thickness of the front baffle 210 may be increased, thereby reducing the deformation of the spacer unit after assembly.

[0062] The present disclosure does not limit the formation method of the boss 620 . For example, in some embodiments, the boss 620 may be integrally formed with the front baffle 210 . Alternatively, the boss 620 may be attached to the front baffle 210 .

[0063] Reference Figure 1 and Figure 4In some embodiments, the edge of the boss 620 away from the block 300 may have at least one concave avoidance notch 700. The avoidance notch 700 may be used for a suction nozzle, that is, the position of the spacer monomer may be sucked and transferred by the suction nozzle, avoiding manual transfer and loading, facilitating assembly line design, and improving the degree of automation. The present disclosure does not limit the number of avoidance notches 700, for example, it may be three, four, etc.

[0064] Reference Figure 4 In the embodiment of the present disclosure, the front baffle 210 or the rear baffle 220 may be formed with an error-proofing structure 800. With such a design, during assembly, the operator can quickly identify the front baffle 210 and the rear baffle 220 according to the error-proofing structure 800 to correctly assemble the spacer unit. The present disclosure does not limit the error-proofing structure 800, for example, it may be Figure 4 Notched shape shown.

[0065] Reference Figure 4 , Figure 9-11 In the embodiment of the present disclosure, the block 300 can be configured as a straight plate, wherein the thickness of the block 300 gradually decreases in the direction away from the plate segment 200. With such a design, since the block 300 is thicker at the connection position with the plate segment 200, the connection strength between the two can be ensured, and the block 300 is prevented from being separated from the plate segment 200 due to force.

[0066] Reference Fig. 9 In some embodiments, the side of the block 300 close to the rear baffle 220 can be constructed as an inclined surface 320 inclined in a direction away from the rear baffle 220. The rear baffle 220 can be used to clamp the battery cell 110 from the side, and the front end of the battery cell 110 can be stopped at the intersection of the inclined surface 320 and the rear baffle 220, and a space for accommodating the battery tab 111 can be formed between the front end surface of the battery cell 110 and the inclined surface 320. With such a design, when the two spacer monomers are assembled for use in a battery, the intersection of the inclined surface 320 and the rear baffle 220 can limit the battery cell 110, and a space can be reserved between the inclined surface 320 and the battery cell 110, which can be used for the multiple tabs 111 led out of the battery cell 110 to bend toward the middle and pass through between the two blocks 300.

[0067] According to a second aspect of the present disclosure, a spacer assembly is provided, comprising two of the above-mentioned spacer monomers for batteries, wherein the two spacer monomers are used to assemble to form the spacer assembly. Since the spacer assembly has all the beneficial effects of the above-mentioned spacer monomers, they are not described in detail here.

[0068] In an embodiment of the present disclosure, the two spacer monomers are detachably connected. Specifically, when the spacer monomer has a first mounting portion 410 and a second mounting portion 420, the first mounting portion 410 and the second mounting portion 420 are detachably connected. With such a design, when the spacer assembly is assembled to the battery, the two spacer monomers can be first arranged at the ends of the battery cell 110, and the pole ear 111 can be passed through the middle of the two abutting ends 310, and the two spacer monomers can be assembled into a spacer assembly and clamp the battery cell 110 through the first mounting portion 410 and the second mounting portion 420. At this time, the pole ear 111 is pressed between the two abutting ends 310. When the battery needs to be disassembled for inspection, the two spacer monomers can be separated by disassembling the first mounting portion 410 and the second mounting portion 420, which is convenient and simple to operate.

[0069] According to a third aspect of the present disclosure, a battery is provided, comprising a battery cell 110 and the above-mentioned spacer assembly. Since the battery has all the beneficial effects of the above-mentioned spacer assembly, they are not described in detail here.

[0070] Reference Fig. 9 In the embodiment of the present disclosure, the rear baffles 220 of the two spacer monomers of the spacer assembly can clamp the battery cell 110 from both sides, and the front end surface of the battery cell 110 stops at the blocks 300 of the two spacer monomers. With such a design, the spacer assembly can clamp the battery cell 110 from three directions to limit the relative movement between the two, without the need to add an additional connection structure to limit the spacer assembly.

[0071] Reference Fig. 9 In some embodiments, the side of the barrier 300 close to the rear baffle 220 may be configured as an inclined surface 320 inclined away from the rear baffle 220, and the front end of the battery cell 110 may stop at the intersection of the inclined surface 320 and the rear baffle 220, and a space for accommodating the tab 111 of the battery cell 110 may be formed between the front end surface of the battery cell 110 and the inclined surface 320. The benefits of such a design can be found in the above related positions, and will not be repeated here.

[0072] According to a fourth aspect of the present disclosure, there is provided an electrical device, comprising the above-mentioned battery. Since the electrical device has all the beneficial effects of the above-mentioned battery, they are not described in detail here.

[0073] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0074] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0075] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
