Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a novel lead-acid battery structure. Background Art

[0002] At present, the two-wheeled electric vehicle market is highly competitive. Long battery life has always been a major hurdle that two-wheeled electric vehicles cannot overcome, and mileage anxiety has always been a pain point for consumers. Due to the limitations of national standard size and weight, the external dimensions of the battery are difficult to increase. Therefore, achieving the maximum capacity in a limited space is the key to solving the problem.

[0003] Since the current common battery structure is a full-impregnation structure (direct-connection impregnation structure), the lead-out and connection busbars are on the same horizontal plane. Since a space for terminal installation needs to be reserved at the lead-out busbar, the busbar height cannot be maximized, resulting in the height of the grid composed of the plate and the separator being difficult to increase, and the capacity is difficult to increase. Therefore, a new lead-acid battery structure is proposed. Utility Model Content

[0004] The utility model aims to provide a novel lead-acid battery structure to solve the problem that the height of the busbar of the fully impregnated structure proposed in the above background technology is limited, resulting in the limited height of the grid and thus the low battery capacity.

[0010] The two lead-out bus bars are respectively connected to at least one outer plate and at least one inner plate in the plate cluster;

[0012] The battery cover corresponding to the connection bus position adopts a direct connection dipped structure;

[0013] An independent sealed lead-out structure is adopted at the position of the battery cover corresponding to the lead-out bus.

[0014] Preferably, the partition has a U-shaped structure.

[0015] Preferably, there are five connecting busbars, dividing the electrode cluster into six electrode groups.

[0016] Preferably, the direct-connected dipping structure comprises a direct-connected dipping tank.

[0017] Preferably, two lead-out busbars are provided, namely a positive lead-out busbar and a negative lead-out busbar.

[0018] Preferably: the sealed lead-out structure comprises a lead-out pole, which is embedded in a color glue groove of the lead-out bus; the lead-out bus is provided with a sealing groove corresponding to the lead-out pole, and an O-ring is provided in the sealing groove.

[0019] Preferably, the sealed lead-out structure further comprises a lead-out terminal, and the lead-out terminal and the lead-out pole are arranged side by side and built into the color glue groove of the lead-out bus.

[0020] Compared with the prior art, the beneficial effects of the utility model are as follows: the structure utilizes the connection bus and the lead-out bus to be set separately, and the lead-out bus is sealed separately by an O-ring, so that a height difference is left between the lead-out bus and the connection bus, so that the lead-out bus can be set almost close to the partition, without considering the safety distance for glue suction, thereby increasing the height of the outer plate and the inner plate while keeping the size of the battery slot unchanged, that is, increasing the capacity of the battery, and the structural setting is simple and efficient, suitable for popularization and use.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1-4 As shown, the utility model provides a technical solution for a novel lead-acid battery structure:

[0028] A novel lead-acid battery structure includes a battery slot 1, a battery cover 101, and a plate cluster located in the battery slot; the plate cluster is formed by stacking an outer plate 2 and a partition 201 in a circular manner, and the partition 201 has an inner plate 203 built therein; the two sides of the plate cluster are outer plates 2; it also includes at least two connecting bus bars 202 and at least two lead-out bus bars 3; the outer plates 2 in the plate cluster are connected to each other through at least one connecting bus bar 202; the inner plates 203 in the plate cluster are connected to each other through at least one connecting bus bar 202 ; The two lead-out bus bars 3 respectively correspond to at least one outer plate 2 and at least one inner plate 203 in the connecting plate cluster; the connecting bus bar 202 and the lead-out bus bar 3 are located at the top of the plate cluster, and the top surface of the connecting bus bar 202 is located on the upper side of the top surface of the lead-out bus bar 3; there is a height difference between the top surfaces of the connecting bus bar 202 and the lead-out bus bar 3; the position of the battery cover 101 corresponding to the connecting bus bar 202 adopts a direct-connected dipped glue structure; the position of the battery cover 101 corresponding to the lead-out bus bar 3 adopts an independent sealed lead-out structure.

[0029] Among them, it should be additionally explained that the partition 201 is of a U-shaped structure, and there are 5 connecting busbars 202, which divide the plate cluster into 6 plate groups. The direct-connected dipping structure includes a direct-connected dipping tank 102, and there are 2 lead-out busbars 3, which are a positive lead-out busbar and a negative lead-out busbar.

[0030] Reference Figure 2 As shown, the sealed lead-out structure includes a lead-out pole 302 , which is built into the color glue groove 103 of the lead-out bus 3 ; the lead-out bus 3 is provided with a sealing groove 104 corresponding to the lead-out pole 302 , and an O-ring 301 is provided in the sealing groove 104 .

[0031] It should be additionally explained that the sealed lead-out structure further includes a lead-out terminal 105 , and the lead-out terminal 105 and the lead-out pole 302 are built side by side in the color glue groove 103 of the lead-out bus 3 .

[0032] By setting and cooperating with the connecting bus 202, the lead-out bus 3 and the O-ring 301, the connecting bus 202 and the lead-out bus 3 are set separately, and the lead-out bus 3 is sealed separately by the O-ring 301, so that a height difference is left between the lead-out bus 3 and the connecting bus 202, so that the lead-out bus 3 can be set almost close to the partition 201 without considering the safety distance for glue suction, thereby increasing the height of the outer plate 2 and the inner plate 203 under the premise of keeping the size of the battery cell 1 unchanged, that is, increasing the capacity of the battery, and the structural setting is simple and efficient, which is suitable for popularization and use.

[0033] It should be noted that the distance between the connecting bus 202 and the partition 201 is a safe distance for glue absorption. Because of the capillary principle, if the partition 201 is too close to the direct-connected glue dipping tank 102 filled with glue, the glue will be absorbed into the partition 201, thereby reducing the sealing of the direct-connected glue dipping tank 102. Therefore, a safe distance for glue absorption is set.

[0034] When assembling this structure, it is necessary to insert the O-ring 301 on the lead-out pole 302, and after covering the battery cover 101, the O-ring 301 is placed in the sealing groove 104. Under the action of the gravity of the battery cover 101, the O-ring 301 will be tightly attached to the groove wall of the sealing groove 104, thereby achieving sealing at the position of the lead-out bus 3.

[0035] It should be additionally explained that the direct-connected glue dipping tank 102 is used to place glue, and the connecting bus 202 is immersed in the glue in the direct-connected glue dipping tank 102 for sealing and insulation.

[0036] It should be additionally explained that the colored glue groove 103 is used to place colored glue to seal the lead pole 302 and the lead terminal 105 and mark the positive and negative poles.

[0037] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
