Description

Technical Field

[0001] The invention relates to the technical field of battery manufacturing, in particular to a battery fixing bracket and a shockproof lead-acid battery. Background Art

[0002] At present, only the inner pole through-wall welding side is fixed between the two single-cell busbars of the battery used in the prior art power vehicles, and the other end is not fixed. During the driving of the power vehicle, with the operation and fluctuation of the vehicle, the positive and negative plates of the battery will vibrate up and down, often causing fatigue fracture at the inner pole through-wall welding, resulting in the scrapping of the battery, thus affecting the normal driving of the power vehicle. Especially for heavy-duty trucks and off-road vehicles, some of the road conditions are very poor during their driving, which will produce a large amplitude of vibration. Therefore, they have higher vibration resistance requirements for batteries, and improving the vibration resistance of batteries is an important problem that needs to be solved. The vibration resistance of lead-acid batteries on the existing market is relatively poor. After dissecting the failed batteries, it was found that the main problem was that the busbar was deformed, causing the plate ear to be disconnected from the busbar and the fatigue fracture at the inner pole through-wall welding. The reason is that during the use of the battery, the pole group and busbar have no appropriate reinforcement design, which eventually leads to the deformation of the busbar and the up and down vibration of the positive and negative plates, which in turn leads to the scrapping of the battery. Summary of the invention

[0003] The object of the present invention is to provide a battery fixing bracket, which can reliably fix the pole group and the busbar, has a simple structure, is quick and convenient to install, and greatly improves the anti-seismic performance of the battery.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A fixing bracket for a battery comprises a first longitudinal plate, a second longitudinal plate, a first transverse plate, a second transverse plate and a third transverse plate, wherein the first transverse plate, the second transverse plate and the third transverse plate are all connected to the first longitudinal plate and the second longitudinal plate to form a rectangular frame structure, and the lower edge of the second transverse plate is lower than the lower edges of the first transverse plate and the third transverse plate; six legs are arranged on the rectangular frame structure, wherein two legs are connected to the first transverse plate and are respectively arranged on the outside of the first longitudinal plate and the second longitudinal plate, two legs are connected to the second transverse plate and are respectively arranged on the outside of the first longitudinal plate and the second longitudinal plate, and the other two legs are connected to the third transverse plate and are respectively arranged on the outside of the first longitudinal plate and the second longitudinal plate.

[0006] Preferably, two supporting protrusions are provided on the outer side of the first transverse plate and the outer side of the third transverse plate.

[0007] Preferably, a first flat plate is provided below the first transverse plate, a second flat plate is provided below the second transverse plate, and a third flat plate is provided below the third transverse plate.

[0008] Further preferably, the cross section of the leg is any one of a cross shape, a straight shape or a T shape.

[0009] In the above technical solution, the first horizontal plate, the second horizontal plate and the third horizontal plate are connected to the first vertical plate and the second vertical plate to form a stable rectangular frame structure, and the lower edge of the second horizontal plate is set lower than the lower edges of the first horizontal plate and the third horizontal plate, so that the lower edge of the second flat plate is lower than the first flat plate and the third flat plate. In this way, when the first flat plate and the third flat plate are against the upper surface of the bus bar, the second flat plate just contacts the pole group, and the first flat plate and the third flat plate have a large contact area with the bus bar to avoid deformation of the bus bar, and the second flat plate prevents the positive and negative plates of the pole group from vibrating up and down. The six legs further support and fix the vertical space of the battery fixing bracket, further avoiding the positive and negative plates of the busbar and the pole group from vibrating up and down and fatigue fracture of the through-wall welding of the inner pole; the two supporting protrusions on the outer side of the first horizontal plate and the outer side of the third horizontal plate further limit the battery fixing bracket, so that the battery fixing bracket is placed just in the single cell of each battery, avoiding the displacement of the battery fixing bracket, making the pole group and the busbar reliably fixed, and the installation is fast and convenient, and the anti-seismic performance of the battery is greatly improved.

[0010] Another object of the present invention is to provide a shockproof lead-acid battery, which has strong shockproof capability and long service life. The following technical solutions are specifically adopted:

[0011] A shockproof lead-acid storage battery comprises a battery slot and a battery cover, wherein six cells are arranged in the battery slot, each cell is equipped with a pole group, two busbars are arranged on each pole group, the busbars are connected to the inner pole column, the battery cover is covered on the battery slot, and also comprises a fixing bracket for the storage battery, wherein the first transverse plate and the third transverse plate are both against the busbars, the second transverse plate is against the pole group, the two legs connected to the first transverse plate and the two legs connected to the third transverse plate are both against two inner walls of the cells, and the two legs connected to the second transverse plate are fixedly connected to the battery cover.

[0012] In the above technical scheme, the first transverse plate and the third transverse plate of the battery fixing bracket are both against the bus, the second transverse plate is just against the pole group, the two legs connected to the first transverse plate and the two legs connected to the third transverse plate are both against two inner walls of the single cell, so as to prevent the battery fixing bracket from shaking horizontally in the single cell, and the two legs connected to the second transverse plate are hot-melt connected to the battery cover, so that the battery fixing bracket is fixed to the battery cover, and the battery fixing bracket is prevented from shaking up and down in the single cell, thereby achieving reliable fixation of the pole group and the bus, quick and convenient installation, greatly improving the anti-seismic performance of the battery, and greatly extending the service life.

[0017] The present invention will be further described below in conjunction with the accompanying drawings:

[0018] like Figures 1 to 4 As shown, the battery fixing bracket comprises a first longitudinal plate 1, a second longitudinal plate 2, a first transverse plate 11, a second transverse plate 12 and a third transverse plate 13, wherein the first transverse plate 11, the second transverse plate 12 and the third transverse plate 13 are all connected with the first longitudinal plate 1 and the second longitudinal plate 2 to form a stable rectangular frame structure, and the lower edge of the second transverse plate 12 is lower than the lower edges of the first transverse plate 11 and the third transverse plate 13, so that when the first transverse plate 11 and the third transverse plate 13 are against the upper surface of the bus bar, the second transverse plate 12 just contacts the pole group, thereby preventing the bus bar from being deformed and the positive and negative plates of the pole group from vibrating up and down; six legs are arranged on the rectangular frame structure, wherein two legs 31 are connected to the first longitudinal plate 1 and the second longitudinal plate 2, and the second transverse plate 12 is connected to the first longitudinal plate 1 and the third transverse plate 13, and the second transverse plate 12 is connected to the pole group. The first horizontal plate 11 is connected and arranged on the outside of the first longitudinal plate 1 and the second longitudinal plate 2, respectively. The two legs 32 are connected to the second horizontal plate 12 and arranged on the outside of the first longitudinal plate 1 and the second longitudinal plate 2, respectively. The other two legs 33 are connected to the third horizontal plate 13 and arranged on the outside of the first longitudinal plate 1 and the second longitudinal plate 2, respectively. The distribution size of the six legs is just matched with the size of the inner wall of the single cell in the battery, so as to prevent the horizontal shaking of the battery fixing bracket in the single cell. The six legs also further support and fix the vertical space of the battery fixing bracket, so as to further prevent the positive and negative plates of the busbar and the pole group from vibrating up and down and fatigue fracture of the inner pole through-wall welding. The cross section of the legs is cross-shaped, straight-shaped or T-shaped, so as to facilitate the hot-melt connection of the legs and the battery cover in the later stage.

[0019] In a preferred embodiment, two supporting protrusions 14 are provided on the outer side of the first horizontal plate 11 and the outer side of the third horizontal plate 13. The two supporting protrusions 14 further limit the position of the battery fixing bracket, so that the battery fixing bracket is placed exactly in the single cell of each battery, thereby preventing the battery fixing bracket from shifting. A first flat plate 21 may be further provided under the first horizontal plate 11, a second flat plate 22 may be provided under the second horizontal plate 12, and a third flat plate 23 may be provided under the third horizontal plate 13. When the first flat plate 21 and the third flat plate 23 are against the upper surface of the busbar, the second flat plate 22 is exactly against the pole group, and the contact area between the first flat plate 21 and the third flat plate 23 and the busbar is greatly increased, further preventing the busbar from being deformed, and the second flat plate 22 further prevents the positive and negative plates of the pole group from vibrating up and down, thereby reliably fixing the pole group and the busbar, with a simple structure, quick and convenient installation, and greatly improved anti-seismic performance of the battery.

[0020] The present invention also relates to a shockproof lead-acid battery, such as Figure 3 , Figure 4 As shown, the battery container 10 includes a battery container 10, a battery cover 20 and a battery fixing bracket 30. Six cells 100 are arranged in the battery container 10. Each cell 100 is equipped with a pole group 4. Two bus bars 5 are arranged on each pole group 4. The bus bars 5 are connected to the inner pole (not shown). The battery cover 20 covers the battery container 10. The first horizontal plate 11 is supported on the bus bars 5 through the first flat plate 21 and the third horizontal plate 13 is supported on the bus bars 5 through the third flat plate 23.

The two legs 31 connected to the first horizontal plate 11 and the two legs 31 connected to the first horizontal plate 11 and the third legs 31 connected to the third horizontal plate 23 are supported on the pole group 4. The two legs 33 connected to the three horizontal plates 13 are both against two inner walls of the single cell 100 to prevent the battery fixing bracket 30 from shaking horizontally in the single cell 100. The two legs 32 connected to the second horizontal plate 12 are fixedly connected to the battery cover 20 by hot melting, so that the battery fixing bracket 30 is fixed to the battery cover 20, thereby achieving reliable fixation of the pole group 4 and the bus bar 5, avoiding the battery fixing bracket 30 from shaking up and down in the single cell 100 and fatigue fracture of the inner pole through-wall welding. The installation is quick and convenient, the anti-seismic performance of the battery is greatly improved, and the service life is greatly extended.
