Description

Technical Field

[0001] The utility model relates to the field of lead-acid batteries, in particular to a protection component and a battery. Background Art

[0002] Lead-acid battery is a widely used rechargeable battery. Lead-acid battery generally includes components such as connectors, terminals, top covers and shells. In the production process of lead-acid batteries, air filters are usually installed on the top cover of the battery by automatic pressing to prevent evaporation of electrolyte and block external dust, impurities, etc. from entering the battery.

[0003] However, in actual use, most battery top covers have a relatively simple structure, and when they are connected and fixed to the battery shell, they often only have the effect of covering and sealing the battery shell. However, since the battery may encounter bumps during transportation, and the top cover cannot provide buffering and protection for the battery shell itself, the battery is subjected to continuous impact, which will have a certain impact on the internal components of the battery. Utility Model Content

[0004] In order to solve the technical problems existing in the prior art, the purpose of the utility model is to provide a protection component to solve the above-mentioned technical problems.

[0006] The protection part is arranged on the battery top cover and can slide on the periphery of the battery shell when the battery top cover and the battery shell are assembled, and comprises a protection frame and a fixing member arranged on the protection frame and fixed to the battery top cover;

[0007] The abutment part is arranged on the battery shell, and when the fixing piece is not fixed to the battery top cover, the protection part can slide down on the abutment part.

[0008] With the protective assembly having the above structure, after the battery top cover and the battery shell are assembled, the protective part originally located on the battery top cover will slide to the periphery of the battery shell and be fixed to the abutment part on the battery shell, so that the protective frame can protect the battery shell and improve the anti-collision performance of the battery during transportation. When the battery top cover is not assembled with the battery shell, the protective assembly is fixed to the battery top cover by fixing parts.

[0009] Preferably, the fixing member includes a connecting column, the connecting column and the protection frame are connected by a first elastic member, and a fixing plate for clamping the battery top cover is also provided in the axial direction of the connecting column. Thus, by bending the fixing plate, the protection part can be unfixed with the battery top cover, and then the protection part slides onto the abutment part, and the protection frame and the fixing member are connected by the first elastic member, which facilitates the fixing or removal of the fixing member and the battery top cover.

[0010] Preferably, the fixing plate is provided with a second rotating shaft, the connecting column is provided with a socket, and the second rotating shaft is installed in the socket. Thus, when the protection part is not fixed to the battery top cover, the direction of the fixing plate can be rotated by the second rotating shaft, thereby removing the protection component.

[0011] Preferably, the abutment portion includes an abutment plate, a slide rail is provided on the abutment plate along the opening direction of the battery housing, and the protection frame is provided with a slide groove, and the slide groove is assembled with the slide rail. Thus, when the protection frame slides around the battery housing, it can slide along the slide rail.

[0012] Preferably, a first positioning portion is further provided on the abutment plate along the opening direction of the battery housing, and a second positioning portion is provided on the protection frame, and the first positioning portion can be assembled with the second positioning portion. Thus, the protection assembly can be firmly fixed to the periphery of the battery housing by assembling the first positioning portion with the second positioning portion.

[0013] Preferably, one of the first positioning portion and the second positioning portion can be a positioning column, and the other can be a positioning hole.

[0014] Preferably, a buffer pad is arranged on the periphery of the protection frame, thereby improving the anti-collision capability of the protection frame.

[0015] The utility model also provides a battery, comprising a battery top cover and the above-mentioned protective assembly, wherein the battery top cover comprises:

[0016] Battery top cover frame;

[0017] The air filter is installed on the battery top cover frame;

[0018] The auxiliary component is arranged on the battery top cover frame and is used to fix the air filter, and comprises a limit plate rotatably hinged on the battery top cover frame, and a limit piece used to fix the rotation of the limit plate.

[0019] The battery top cover with the above structure, after the battery top cover frame and the air filter are installed to each other, the limit plate on the battery top cover frame can be rotated to abut against the air filter, and the limit member fixes the rotation direction of the limit plate, so that the limit plate always presses the air filter, thereby improving the stability between the air filter and the battery top cover frame.

[0020] Preferably, the limiting member includes a connecting member and a second elastic member, and the connecting member is connected to the battery top cover frame through the second elastic member. Thus, when the limiting plate fixes the air filter, the connecting member fastens the limiting plate under the action of the elastic potential energy of the second elastic member.

[0034] In order to better understand the technical solution of the present utility model, the embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0035] It should be clear that the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of 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.

[0036] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0037] In order to better illustrate a battery, the concepts of X, Y, and Z axes are cited, and the three mutually orthogonal spatial axes are taken as X-axis, Y-axis, and Z-axis, such as Figures 1 to 7 As shown in the coordinate axes, when the battery cover 2 is installed on the top of the battery housing 1, the +Z axis is defined as the direction from the battery housing 1 to the battery cover 2 (i.e., from bottom to top), the +X axis direction is defined as the direction from left to right of the battery housing 1, and the +Y axis direction is defined as the direction from back to front of the battery housing 1. The front-to-back or up-and-down movement or the movement along the X-axis, Y-axis, and Z-axis in the embodiments is not limited to the movement vertically, horizontally, or parallel to the direction, and the movement with an inclined angle is also acceptable, as long as there is a movement of a component in the direction, it is counted.

[0038] A battery top cover, such as Figure 1-3 As shown, the battery top cover 2 is used to be installed with the battery shell 1. The battery shell 1 is roughly a rectangular parallelepiped and is used to be installed on the battery module. The battery top cover 2 is roughly rectangular and can be installed on the battery shell 1. A protective component 3 is provided on the battery top cover 2. The protective component 3 can slide to the periphery of the battery shell 1 to protect the battery shell 1 from external impact and damage to the battery module.

[0039] like Figure 5As shown in the figure, the battery top cover 2 includes a battery top cover frame 21, a filter element 22, and an auxiliary component 23. The battery top cover frame 21 is generally rectangular, and is provided with an installation through groove 211 therein. The installation through groove 211 is used for installing the filter element 22, and the filter element 22 is used to prevent the evaporation of the electrolyte and block external dust, impurities, etc. from entering the battery interior. The auxiliary component 23 is arranged on both sides of the battery top cover frame 21 in the X-axis direction. After the filter element 22 is installed on the battery top cover frame 21, the auxiliary component 23 can fasten the filter element 22 to prevent the filter element 22 from falling off due to vibration during the use or transportation of the battery. Specifically, in this embodiment, both the filter element 22 and the installation through groove 211 are generally rectangular. Mounting seats 212 are symmetrically arranged on both sides of the battery top cover frame 21, and the auxiliary component 23 is installed on the mounting seats 212 to fasten the filter element 22 at the same time.

[0040] Furthermore, as Figure 6-7 shown, the auxiliary component 23 includes a limiting plate 231 and a limiting member 232. The limiting plate 231 is rotatably hinged on the mounting seat 212 of the battery top cover frame 21. The limiting member 232 is arranged on the side of the mounting seat 212 in the Y-axis direction and away from the limiting plate 231. When the limiting plate 231 rotates to press the filter element 22, the limiting member 232 can fix the rotation direction of the limiting plate 231 so that the limiting plate 231 always tightly presses the filter element 22. Specifically, in this embodiment, the limiting plate 231 is generally a rectangular plate, and a first rotating shaft 2311 is arranged on one side of the limiting plate 231. Both ends of the first rotating shaft 2311 are rotatably hinged on the mounting seat 212. A second clamping portion 2312 is arranged on the end face of one end of the first rotating shaft 2311. A through hole is formed in the mounting seat 212, and the limiting member 232 can be clamped with the limiting plate 231 through the through hole.

[0041] Even further, as Figure 6 shown, the limiting member 232 includes a connecting member 2321, a second elastic member 2322, and a first clamping portion 2323. The connecting member 2321 and the mounting seat 212 are elastically connected by the second elastic member 2322. The first clamping portion 2323 is arranged on the second elastic member 2322. When the connecting member 2321 fastens the limiting plate 231, the first clamping portion 2323 is clamped with the second clamping portion 2312. The first clamping portion 2323 is a rectangular block, and the second clamping portion 2312 is a rectangular groove adapted to the rectangular block; specifically, in this embodiment, the connecting member 2321 is generally in a "C" shape. One end of the connecting member 2321 is fixed to the first clamping portion 2323, and the other end thereof is fixed to the second elastic member 2322. In a possible case, the first clamping portion 2323 is a rectangular groove, and the second clamping portion 2312 is a rectangular block.

[0042] Preferably, the second elastic member 2322 is a spring.

[0043] Working principle of the battery top cover 2: After the air filter 22 is assembled with the battery top cover 2, the limit plate 231 can be rotated with the axis of the first rotating shaft 2311 as the rotation line so that the limit plate 231 contacts the air filter 22, and then the elastic potential energy of the second elastic member 2322 drives the connecting member 2321 to move toward the limit plate 231, and the connecting member 2321 drives the first clamping portion 2323 to clamp with the second clamping portion 2312 set on the end face of the first rotating shaft 2311 to fix the direction of the limit plate 231, so that the installed air filter 22 can be fixed to ensure the stability of its connection with the main body of the battery top cover 2.

[0044] A protective component, such as Figure 2-3 As shown, it is used to protect the battery shell 1, including a protective part 31 and an abutment part 32. The protective part 31 includes a protective frame 311 and a fixing member 312 on the Z-axis direction of the protective frame 311. When the fixing member 312 is fixed to the battery top cover 2, the protective frame 311 is set at the bottom of the battery top cover 2 in the Z-axis direction. When the fixing member 312 is not fixed to the battery top cover 2, the protective frame 311 can slide on the periphery of the battery shell 1. The abutment part 32 is set on the battery shell 1 and is located on both sides of the X-axis direction. Specifically, in this embodiment, four groups of fixing members 312 are provided, all of which are located on the protective frame 311 and are symmetrically arranged, and two groups of abutment portions 32 are provided, which are symmetrically arranged on both sides of the battery shell 1; when the protective frame 311 protects the battery shell 1, the fixing members 312 are not fixed to the battery top cover 2, and the protective portion 31 can slide on the abutment portion 32; when the protective portion 31 is fixed to the battery top cover 2, the protective portion 31 can be separated from the battery shell 1 along with the battery top cover 2.

[0045] Furthermore, a buffer pad 313 is disposed on the periphery of the protection frame 311 .

[0046] like Figure 3-4 As shown, the fixing member 312 includes a connecting column 3121, a first elastic member 3122 and a fixing plate 3123. The bottom of the connecting column 3121 is connected to the protection frame 311 through the first elastic member 3122. The protection frame 311 is provided with a mounting hole for mounting on the first elastic member 3122. The fixing plate 3123 is arranged on the top of the connecting column 3121. When the protection part 31 is fixed to the battery top cover 2, the fixing plate 3123 abuts against the top of the battery top cover 2 for fixing. The protection frame 311 is fastened to the bottom of the battery top cover 2 under the elastic force of the first elastic member 3122. Specifically, in this embodiment, the connecting column 3121 is roughly a long rectangular column, the fixing plate 3123 is a square plate, and the fixing plate 3123 is rotatably connected to the connecting column 3121.

[0047] Preferably, the first elastic member 3122 is a spring.

[0048] Furthermore, the fixing plate 3123 is provided with a second rotating shaft 3124 at the bottom in the Z-axis direction, and the connecting column 3121 is provided with a plug hole 31211 at the top in the Z-axis direction, and the plug hole 31211 is substantially a circular hole. The second rotating shaft 3124 is installed in the plug hole 31211, and the fixing plate 3123 rotates on the top of the connecting column 3121.

[0049] like Figure 3 As shown, the abutment portion 32 includes an abutment plate 321 and a slide rail 322. The abutment plate 321 is arranged on the side of the battery housing 1, and the slide rail 322 is located on the abutment plate 321 and arranged along the +Z axis direction. Specifically, in this embodiment, the abutment plate 321 is approximately a rectangular plate, and the slide rail 322 is also approximately a rectangular plate. The slide rail 322 is perpendicular to the abutment plate 321. The protection frame 311 is provided with a slide groove 3111, which is approximately a rectangular through groove. The slide groove 3111 is assembled with the slide rail 322. When the protection frame 311 slides on the periphery of the battery housing 1, the protection frame 311 can be kept horizontally lifted.

[0050] Furthermore, if Figure 3 As shown, the abutment plate 321 is further provided with a first positioning portion 3211 along the Z-axis direction, and the protection frame 311 is provided with a second positioning portion 3112. When the protection portion 31 can slide onto the abutment portion 32, the first positioning portion 3211 can be assembled with the second positioning portion 3112 to prevent the protection portion 31 from shaking around the battery housing 1. Specifically, in this embodiment, the first positioning portion 3211 is a positioning column, which is substantially a cylinder, and the second positioning portion 3112 is a positioning hole, which is substantially a circular hole. In a possible case, the first positioning portion 3211 is a positioning hole, and the second positioning portion 3112 is a positioning column.

[0051] The working principle of a protective component is as follows: when the battery shell 1 and the battery top cover 2 are connected and the battery is assembled as a whole, the connecting column 3121 is moved upward, so that the first elastic member 3122 is deformed, and the fixing plate 3123 is rotated horizontally with the second rotating shaft 3124 as the axis, and then the elastic action of the first elastic member 3122 can drive the connecting column 3121 to move down and reset. At this time, the fixing plate 3123 also separates from the top surface of the battery top cover 2 body, so that the protective frame 311 can move downward on the periphery of the lead-acid battery shell and contact the abutment plate 321 after moving downward, and the first positioning portion 3211 can be engaged with the second positioning portion 3112 to fix the protective frame 311, so that the impact force generated by the bumps during the transportation of the battery can be effectively offset by the buffer pad 313 arranged on the surface of the protective frame 311, thereby reducing the impact of the impact force on the internal components of the battery, thereby improving the practicality of the device.

[0052] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
