Description

Technical Field

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

[0002] A bipolar horizontal lead-acid battery is a typical type of lead-acid battery. A lead-acid battery is an electrochemical device consisting of a positive plate, a negative plate, and an electrolyte that converts chemical energy into electrical energy for storage. In a bipolar horizontal lead-acid battery, both the positive and negative plates are coated with active materials, allowing them to be both charged and discharged, which means that the battery can be used as a power source to supply electricity while also storing electrical energy for later use.

[0003] However, the existing bipolar horizontal lead-acid batteries still have certain problems. For example, during use, the battery module in the bipolar horizontal lead-acid battery will generate high temperature. When running under high temperature conditions, the shell needs to have a certain stability to ensure the stable operation of the bipolar horizontal lead-acid battery. However, the existing battery shells are prone to expansion or deformation when running for a long time at high temperature, and cannot have a good thermal stability effect, which affects the normal use of the bipolar horizontal lead-acid battery.

[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 understand a battery, the concepts of X, Y, and Z axes are used, and the three mutually orthogonal spatial axes are taken as X, Y, and Z axes, such as Figures 1 to 7 As shown in the coordinate axis, when the heat dissipation battery cover 1 is installed on the top of the battery housing 3, the +Z axis is defined as the direction of the battery housing 3 toward the heat dissipation battery cover 1 (i.e., from bottom to top), the +X axis direction is defined as the direction of the battery housing 3 from left to right, and the +Y axis direction is defined as the direction of the battery housing 3 from back to front. The front-to-back or up-and-down movement or movement along the X-axis, Y-axis, and Z-axis in the embodiment is not limited to movement vertically, horizontally, or parallel to the direction, and movement with an inclined angle is also acceptable, as long as there is a component movement in the direction, it is counted.

[0038] A heat dissipation battery top cover, such as Figure 1-3 As shown, the heat dissipation battery top cover 1 is installed in the Z-axis direction of the battery housing 3 to dissipate heat for the battery module (not shown) in the battery housing 3. The battery housing 3 is roughly a cuboid, and the heat dissipation battery top cover 1 is roughly a rectangle.

[0039] like Figure 1-3 As shown, the heat dissipation battery top cover 1 includes a cover plate 11, a heat dissipation element 12 and a control unit 13. The cover plate 11 is roughly rectangular, and at least one heat dissipation element 12 is provided on the cover plate 11. At least one control unit 13 is also provided on the cover plate 11. When the battery module is cooled, the control unit 13 can control the heat dissipation element 12 to exhaust air from the inside of the battery housing 3. Specifically, in this embodiment, four heat dissipation elements 12 are provided on the cover plate 11, and the control unit 13 is a signal controller, which is an existing arbitrary signal control receiving device and has the function of receiving and transmitting signals.

[0040] like Figure 4-5 , combined Figure 6As shown, the cover plate 11 is provided with a ventilation pipe 111, the cross-sectional area of ​​the ventilation pipe 111 is roughly circular, the ventilation pipe 111 is arranged through along the Z-axis direction, a fixing frame 1111 is arranged inside the ventilation pipe 111, and the heat dissipation element 12 is installed on the fixing frame 1111, and the heat dissipation element 12 discharges heat from the inside of the battery housing 3 through the ventilation pipe 111. Specifically, in this example, a ventilation hood 112 can be detachably installed at the pipe mouth of the ventilation pipe 111, and the ventilation hood 112 is installed at the pipe mouth of the ventilation pipe 111 to prevent external dust and particulate matter from entering the battery from the ventilation pipe 111. The ventilation hood 112 is roughly a circular hood, and a plurality of exhaust holes 1121 are opened on the side.

[0041] Furthermore, a plurality of clamping blocks 1112 are arranged on the periphery of the pipe mouth of the ventilation pipe 111. When the ventilation hood 112 is installed at the pipe mouth of the ventilation pipe 111, the ventilation hood 112 can be clamped and fixed. A filter plate 1113 is arranged on the bottom of the ventilation pipe 111 in the Z-axis direction. The filter plate 1113 is provided with a plurality of through holes for heat dissipation, and also can prevent external dust and particulate matter from entering the battery. Specifically, in this example, four clamping blocks 1112 are arranged on the periphery of the pipe mouth of the ventilation pipe 111 in a circular array with the Z-axis direction as the axis.

[0042] like Figure 1 As shown, the cover plate 11 is also provided with a power connection hole 113. The power connection hole 113 is electrically connected to the battery module in the battery housing 3, so as to facilitate power supply to an external device. Specifically, in this example, two power connection holes 113 are provided, which are electrically connected to the positive and negative poles of the battery module.

[0043] like Figure 1 As shown, the cover plate 11 is also provided with a connection hole 114. In the face of different installation conditions, different fixing methods are used. The cover plate 11 can be flexibly used in the case where there are fixing parts on the top of the existing equipment, which is convenient for quick installation and disassembly.

[0044] like Figure 5 As shown, the heat dissipation element 12 is a heat dissipation fan, which includes a motor 121 and a heat dissipation fan blade 122 installed at the output end of the motor 121. The heat dissipation fan blade 122 is driven by the motor 121 to rotate, thereby dissipating heat inside the battery housing 3. Specifically, in this example, the motor 121 is fixed on the fixing frame 1111 and is electrically connected to the control unit 13. In a possible case, the heat dissipation element 12 is a micro air pump.

[0045] The working principle of the heat dissipation battery top cover: after the battery module is placed in the battery housing 3, the heat dissipation element 12 can be opened through the control unit 13 during operation. The interior of the battery housing 3 will generate a large amount of heat due to the operation of the battery module. The heat inside the battery housing 3 can be discharged through the heat dissipation element 12 by utilizing the exhaust effect of the heat dissipation fan, and then the hot air is discharged through the exhaust holes 1121 on the side of the ventilation hood 112. Thereby, the stability of the battery module when working inside the battery housing 3 is improved, and the expansion or deformation of the battery housing 3 when the battery module is working is reduced.

[0046] An auxiliary pressing component, such as Figure 1-2 As shown, the auxiliary pressing assembly 2 is arranged in the Y-axis direction of the battery housing 3 and forms a symmetrical arrangement, which is used to fix the heat dissipation battery top cover 1 installed on the battery housing 3 to prevent the heat dissipation battery top cover 1 from being separated from the battery housing 3 during use, and includes a limit plate 21 and a telescopic part 22. The telescopic part 22 is arranged on the outside of the battery housing 3, and the limit plate 21 is fixed to the output end of the telescopic part 22. The output end of the telescopic part 22 is telescoped along the Z-axis direction of the battery housing 3; when the output end of the telescopic part 22 is extended, the limit plate 21 is away from the battery housing 3; it is convenient for the heat dissipation battery top cover 1 to be installed on the battery housing 3; when the output end of the telescopic part 22 is shortened, the limit plate 21 is fastened to the heat dissipation battery top cover 1.

[0047] like Figure 7 As shown, the limiting plate 21 is provided with a pressure pad 211, and the pressure pad 211 is arranged at the bottom of the limiting plate 21. When the limiting plate 21 is fastened to the heat dissipation battery top cover 1, it can fit with the heat dissipation battery top cover 1; specifically, in this embodiment, the pressure pad 211 is in the shape of a strip, and four strips are arranged at the bottom of the limiting plate 21. The material of the pressure pad 211 is relatively soft, and the pressure pad 211 can fit tightly with the heat dissipation battery top cover 1, which can fully ensure that the limiting plate 21 is pressed on the top of the battery shell 3, thereby enhancing the stability of the heat dissipation battery top cover 1 and the battery shell 3.

[0048] like Figure 7 As shown, the telescopic portion 22 includes a mounting seat 221, an elastic element 222 and a sliding column 223. The elastic element 222 is installed in the mounting seat 221, and one end of the elastic element 222 is fixed to the mounting seat 221, and the other end is fixed to the sliding column 223. The sliding column 223 can be extended or shortened through the elastic deformation of the elastic element 222. Specifically, in this embodiment, the sliding column 223 is a circular column and the elastic element 222 is a spring.

[0049] Furthermore, the mounting base 221 includes a shell 2211 and a cover body 2212. The shell 2211 is fixed on the outer side wall of the battery shell 3 in the Y-axis direction. A mounting plate 224 is arranged in the shell 2211. The cover body 2212 is installed on the shell 2211. A through hole 2213 is opened on the cover body 2212. Two groups of elastic elements 222 are arranged on both sides of the mounting plate 224. One end of the two groups of elastic elements 222 is fixed to the mounting plate 224 and the other end is fixed to the bottom of the cover body 2212. The sliding column 223 is installed in the middle of the mounting plate 224. When the sliding column 223 is extended, the elastic element 222 is in a contracted deformation state. When the sliding column 223 is shortened, the elastic element 222 is in a restored state. In one possible scenario, the mounting plate 224 is fixed in the housing 2211 , one end of the elastic element 222 is mounted on the mounting plate 224 , and the other end of the elastic element 222 is fixed to the sliding column 223 , so that the sliding column 223 can move in the through hole 2213 .

[0050] The working principle of an auxiliary pressing assembly is as follows: after the battery module is placed inside the battery housing 3, the heat dissipation battery top cover 1 is installed on the battery housing 3, and the sliding column 223 automatically rebounds to its original position upon receiving the pulling force of the elastic element 222, so that the limiting plate 21 is fastened to the top of the heat dissipation battery top cover 1, and the pressure pad 211 fits tightly, which can effectively ensure that the heat dissipation battery top cover 1 will not be separated from the battery housing 3 during use.

[0051] 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.
