DETAILED DESCRIPTION

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

[0045] In the present disclosure, unless otherwise stated, the orientation words such as "inner, outer", "front, back" used according to the context can be based on the structure of the relevant parts themselves, or based on the orientation when the relevant parts are used together, for example: the stop is located on the plate surface of the plate segment to separate the plate segment into a "front" baffle located on one side of the stop and a "back" baffle located on the other side of the stop, here "front and back" are defined when the spacer ring is installed between the battery cell and the cover plate, the side close to the cover plate is "front", and the side close to the cell is "back"; the edge of the "boss" away from the stop forms at least one "concave" avoiding gap, here "concave" means concave towards the direction close to the stop.

[0046] In the present disclosure, the terms "first", "second" and the like are used to distinguish one element from another element, and do not have sequential and important nature. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated.

[0047] In order to facilitate the understanding of the technical scheme, the battery structure is introduced first, referring to FIG. 9, the battery includes a shell 130, an installed cell 110 in the shell 130, a tab 111 led out by the cell 110, a cover plate 120 buckled on the shell 130, and a spacer ring assembly installed between the cover plate 120 and the end of the cell 110. The cover plate 120 is provided with a pole, and the tab 111 led out from the cell 110 passes through the spacer ring assembly to connect the pole. Specifically, a passage can be provided on the spacer ring assembly for the tab 111 to pass through, or the tab 111 can be pre-pressed by two spacer ring bodies as will be described below. This will be described in detail below, and will not be explained here. The present disclosure is related to the improvement of the structure of the above-mentioned spacer ring assembly.

[0048] Referring to FIGS. 1-9, the present disclosure exemplarily shows a spacer ring body 1 for a battery, comprising a plate segment 200 and a stop 300 connected at an angle, the stop 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 stop 300 and a back baffle 220 located on the other side of the stop 300.

[0049] The present disclosure does not limit the shape of the stop 300, for example, it can be configured as a plate as will be described below, or it can be block-shaped, irregularly shaped, etc., as long as it can separate the plate segment 200 into the front baffle 210 and the back baffle 220. The stop 300 can be integrally formed with the plate segment 200, or can be in an assembled relationship.

[0050] In embodiments of the present disclosure, the plate segment 200 and the baffle 300 can be equal in length, and the baffle 300 is located at the center of the plate segment 200. Alternatively, in other embodiments, the plate segment 200 can be longer than the baffle 300, and the baffle 300 is located near one side of the plate segment 200.

[0051] By using the above technical solution, when the two spacer monomers 1 are butt-jointed to form the spacer assembly 2 and installed between the cover plate 120 of the battery 3 and the battery cell 110 of the battery 3 during the assembly of the battery, referring to FIG. 9, the rear baffle 220 of the two spacer monomers 1 can respectively extend to the outside of the side wall of the battery cell 110, so that the spacer assembly 2 can be clamped from three directions (two sides of the battery cell 110 and the end face of the battery cell 110 facing the cover plate 120), thereby the movement of the spacer assembly 2 can be limited by the battery cell 110, and there is no need to additionally add a connecting structure (such as a buckle) for the spacer assembly 2 to limit the displacement of the spacer assembly 2. In addition, a containing space for accommodating the tab 111 of the battery cell 110 can be formed between the two front baffles 210, so as to avoid the tab 111 from contacting the shell 130 of the battery and causing short circuit. In this way, the structure of the spacer monomer 1 can be simplified, the assembly process difficulty of the spacer monomer 1 can be reduced, and better limiting effect of the spacer monomer 1 can be achieved. In addition, the simplified spacer monomer 1 has more flat surfaces, which is more conducive to automatic grabbing during automatic production.

[0052] Referring to FIGS. 1-9, in embodiments of the present disclosure, the end of the baffle 300 away from the plate segment 200 is defined as the abutting end 310, wherein the spacer monomer 1 can be configured to press the tab 111 of the battery when assembled with another spacer monomer 1, and the abutting ends 310 of the two spacer monomers 1 are close to each other. In some embodiments, the tab 111 can be pressed at the root portion of the tab 111, which refers to the portion of the tab 111 close to the battery cell 110. This portion is relatively stable compared to the tail portion or the middle portion, because it is closer to the battery cell 110, has greater constraint force and stronger bending resistance. By pre-pressing the tab 111 (interference fit) by the abutting ends 310 of the two spacer monomers 1, the spacer monomer 1 and the tab 111 can form an integral whole, that is, the tab 111 can limit the displacement of the spacer monomer 1, thereby further improving the stability of the spacer assembly 2. It should be explained that, in embodiments of the present disclosure, the abutting end 310 refers to the portion for abutting with the tab 111, for example, the end face of the baffle 300 away from the plate segment 200.

[0053] In embodiments of the present disclosure, the material of the portion of the baffle 300 used to abut the tab 111 of the battery can be an elastic material, such as rubber or the like. In this way, after the tab 111 is clamped by the two baffles 300, the baffle 300 is deformed by the tab 111, and the deformation can generate an elastic force to press the tab 111 tightly, thereby increasing the friction between the tab 111 and the spacer monomer 1, so that the spacer monomer 1 is not easily detached from the tab 111 or displaced.

[0054] In order to increase the friction between the abutting end 310 and the tab 111 to limit the spacer monomer 1 from being detached from the tab 111 or displaced, in some embodiments, the abutting end 310 can be formed with a friction structure 311. The friction structure 311 can be a friction texture formed on the abutting end 310, or can also be a non-slip pad attached to the abutting end 310, and the present disclosure does not limit this.

[0055] Referring to FIGS. 1-8, 10-11, in embodiments of the present disclosure, the spacer monomer 1 can further include a first mounting portion 410 and a second mounting portion 420, the first mounting portion 410 being provided at one end of the plate segment 200 and the baffle 300 in the extension direction, and the second mounting portion 420 being provided at the other end of the plate segment 200 and the baffle 300 in the extension direction. In this way, when two spacer monomers 1 are assembled into a spacer assembly 2, the first mounting portion 410 of one spacer monomer 1 is connected to the second mounting portion 420 of the other spacer monomer 1, and the second mounting portion 420 of one spacer monomer 1 is connected to the first mounting portion 410 of the other spacer monomer 1. When actually mounted, the abutting ends 310 of the two spacer monomers 1 are opposite to each other, and the two spacer monomers 1 are arranged in reverse in the length direction. When the spacer monomer 1 is assembled into the battery, the two spacer monomers 1 can be arranged at the end of the battery cell 110, and the tab 111 can be passed between the two abutting ends 310, and the two spacer monomers 1 can be assembled into the spacer assembly 2 through the first mounting portion 410 and the second mounting portion 420. At this time, the tab 111 is pressed between the two abutting ends 310.

[0056] The present disclosure does not limit the specific structure of the first mounting portion 410 and the second mounting portion 420. For example, in the embodiments shown in FIGS. 1-5, the first mounting portion 410 can include a first mounting seat 411 and a buckle 412 located on the first mounting seat 411, and the second mounting portion 420 can include a second mounting seat 421 and a clamping groove 422 located on the second mounting seat 421. Through the cooperation of the buckle 412 and the clamping groove 422, the detachable cooperation of the two spacer monomers can be achieved. In embodiments of the present disclosure, the buckle 412 can be a mushroom buckle, and the clamping groove 422 can be a mushroom buckle hole. In addition, in some other embodiments, the buckle 412 can be a crosspin buckle, an expansion buckle, or the like.

[0057] Referring to FIGS. 10-11, in embodiments 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 clamping groove 422, and the end surface of the abutting end 310 can be flush. In this way, when the buckle 412 is inserted into the clamping groove 422 and clamped in place (the first surface 413 and the second surface 423 abut 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 clamped in place, the two abutting ends 310 can abut each other to clamp the tab 111 therebetween. In addition, in other embodiments, the abutting end 310 can 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 abut, a gap is left between the two abutting ends 310 for the tab 111 to pass through, but in order to achieve the pressing of the tab 111, the thickness of the gap can be less than the thickness of the tab 111.

[0058] Referring to FIGS. 1-8, in embodiments of the present disclosure, the first mounting seat 411 and the second mounting seat 421 can each have a first liquid injection hole 510, one end of which is used to face the cover plate 120 of the battery, and the other end is used to face the battery cell 110. It needs to be explained that the liquid injection hole is also a liquid injection channel, which is used to fill or adjust the liquid level of the electrolyte in the battery to maintain the required liquid level height for the normal operation of the battery. At the same time, the liquid level hole is also the outlet for the discharge of gas and water vapor during the charging of the lead-acid battery, and these gases and water vapor are discharged to the external environment through the liquid level hole, thereby ensuring the safe and stable operation of the battery. By respectively providing the first mounting seat 411 and the second mounting seat 421 with the first liquid injection hole 510, the battery can be filled with liquid at the same time. And since this scheme does not need to additionally provide a buckle point for connecting the battery shell on the side of the first mounting seat 411 and the second mounting seat 421, the position does not need to be provided with a reinforcing rib, that is, the flow path of the first liquid injection hole 510 can be used for liquid injection in its entirety, compared with the traditional spacer assembly 2 (since the buckle point is provided, the reinforcing rib needs to be provided at the position of the liquid injection hole), in this way, the design does not affect the liquid injection flow rate, and the liquid injection efficiency is improved.

[0059] Referring to FIGS. 1-8, in embodiments of the present disclosure, the barrier 300 can form a second liquid injection hole 520, one end of which is used to face the cover plate 120 of the battery, and the other end is used to face the battery cell 110. By providing the barrier 300 with the second liquid injection hole 520, the liquid injection efficiency can be improved. The number of the second liquid injection hole 520 can be multiple.

[0060] It should be noted that, in the case of only the first liquid injection hole 510, in the extension direction of the plate segment 200 and the baffle 300, the two ends of the battery cell 110 extend at least to the first mounting seat 411 and the second mounting seat 421 to inject liquid through the first liquid injection hole 510.

[0061] Referring to FIGS. 1-5 and 9, in an embodiment of the present disclosure, a convex edge 610 can be formed at the edge of the side of the front baffle 210 facing away from the baffle 300. The length of the convex edge 610 can be equal to that of the front baffle 210, and the present disclosure does not limit this. When assembling, the spacer monomer 1 is first mounted to the end of the battery cell 110, and then the insulating film is wrapped around the battery cell 110 and the outer side of the spacer monomer 1 to prevent the pole piece of the battery cell 110 from contacting the shell 130 and short-circuiting. The thickness of the convex edge 610 can be greater than or equal to the thickness of the film 140, and the edge position of the film 140 is attached to the position adjacent to the convex edge 610 on the outer side of the spacer monomer 1. In this way, when the battery cell 110, the film 140, and the spacer assembly 2 are inserted into the shell 130, the convex edge 610 can prevent the edge position of the film 140 from being scratched by the shell 130 and causing the edge position to be raised, 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, so as to be able to reduce the deformation amount of the spacer monomer 1 after assembly. The above advantages make it easy for the battery cell 110 to enter the shell (the shell 130).

[0062] The present disclosure does not limit the forming method of the convex edge 610. For example, in some embodiments, the convex edge 610 can be integrally formed with the front baffle 210. Alternatively, the convex edge 610 can be attached to the outer edge of the front baffle 210.

[0063] Referring to FIGS. 1-5 and 9, in an embodiment of the present disclosure, a convex edge 610 can be formed at the edge of the side of the front baffle 210 facing away from the baffle 300. The length of the convex edge 610 can be equal to that of the front baffle 210, and the present disclosure does not limit this. When assembling, the spacer monomer 1 is first mounted to the end of the battery cell 110, and then the insulating film is wrapped around the battery cell 110 and the outer side of the spacer monomer 1 to prevent the pole piece of the battery cell 110 from contacting the shell 130 and short-circuiting. The thickness of the convex edge 610 can be greater than or equal to the thickness of the film 140, and the edge position of the film 140 is attached to the position adjacent to the convex edge 610 on the outer side of the spacer monomer 1. In this way, when the battery cell 110, the film 140, and the spacer assembly 2 are inserted into the shell 130, the convex edge 610 can prevent the edge position of the film 140 from being scratched by the shell 130 and causing the edge position to be raised, 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, so as to be able to reduce the deformation amount of the spacer monomer 1 after assembly. The above advantages make it easy for the battery cell 110 to enter the shell (the shell 130).

[0064] The present disclosure does not limit the forming method of the convex edge 610. For example, in some embodiments, the convex edge 610 can be integrally formed with the front baffle 210. Alternatively, the convex edge 610 can be attached to the outer edge of the front baffle 210.

[0065] Referring to FIG. 1 and FIG. 4, in some embodiments, the edge of the boss 620 away from the barrier 300 can have at least one concave relief gap 700. The relief gap 700 can be used for a suction nozzle, i.e. the position of the spacer monomer 1 can be transferred by the suction nozzle, avoiding manual transfer of the material, facilitating the assembly of the production line design, and improving the degree of automation. The number of relief gaps 700 is not limited in the present disclosure, for example, it can be three, four, etc.

[0066] Referring to FIG. 4, in embodiments of the present disclosure, the front baffle 210 or the rear baffle 220 can be formed with an error-proof structure 800. In this way, during assembly, the operator can quickly identify the front baffle 210 and the rear baffle 220 according to the error-proof structure 800 to correctly assemble the spacer monomer 1. The error-proof structure 800 is not limited in the present disclosure, for example, it can be a gap as shown in FIG. 4.

[0067] Referring to FIG. 4, FIG. 9-FIG. 11, in embodiments of the present disclosure, the barrier 300 can be configured as a straight plate, wherein the thickness of the barrier 300 gradually decreases in the direction away from the plate segment 200. In this way, due to the larger thickness of the connection position of the barrier 300 and the plate segment 200, the connection strength between the two can be ensured, avoiding the separation of the barrier 300 and the plate segment 200 under stress.

[0068] Referring to FIG. 9, in some embodiments, the side of the barrier 300 close to the rear baffle 220 can be configured as an inclined surface 320 inclined towards the direction away from the rear baffle 220. Wherein the rear baffle 220 can be used to clamp the cell 110 of the battery from the side, the front end of the cell 110 can be stopped at the intersection position of the inclined surface 320 and the rear baffle 220, and the front end surface of the cell 110 can form a space with the inclined surface 320 for accommodating the tab 111 of the battery. In this way, when two spacer monomers 1 are assembled for a battery, the intersection position of the inclined surface 320 and the rear baffle 220 can limit the cell 110, and a space can be reserved between the inclined surface 320 and the cell 110, which can be used for the multiple tabs 111 of the cell 110 to be bent towards the middle and pass between the two barriers 300.

[0069] According to a second aspect of the present disclosure, a spacer assembly 2 is provided, comprising two spacer monomers 1 for a battery as described above, wherein the two spacer monomers 1 are used to assemble to form the spacer assembly 2, which has all the beneficial effects of the spacer monomer 1 described above, which will not be repeated here.

[0070] In the embodiments of the present disclosure, the two spacer monomers 1 are detachably connected. Specifically, when the spacer monomer 1 has the first mounting portion 410 and the second mounting portion 420, the first mounting portion 410 and the second mounting portion 420 are detachably connected. In this way, when the spacer assembly 2 is assembled to the battery, the two spacer monomers 1 can be arranged at the end of the battery cell 110 first, and the tab 111 is passed through the middle of the two abutting ends 310, and the two spacer monomers 1 are assembled into the spacer assembly 2 and clamped the battery cell 110 through the first mounting portion 410 and the second mounting portion 420. At this time, the tab 111 is pressed between the two abutting ends 310. When the battery 3 needs to be disassembled for maintenance, the two spacer monomers 1 can be separated by disassembling the first mounting portion 410 and the second mounting portion 420, which is convenient and simple to operate.

[0071] According to a third aspect of the present disclosure, a battery 3 is provided, comprising a battery cell 110 and the above-mentioned spacer assembly 2, since the battery has all the beneficial effects of the above-mentioned spacer assembly 2, which will not be repeated here.
