Technical Field

[0001] The utility model relates to the technical field of battery pack power display, in particular to a battery pack power display structure. Background Art

[0002] As the core component of electric vehicles, energy storage systems and other equipment, the technological development of battery packs is directly related to the performance, safety and cost of the equipment. With the rapid development of the new energy vehicle market, the technical requirements for battery packs are becoming higher and higher.

[0003] In the existing battery pack power display technology, LED is usually used to directly display the power status, or an LCD display combined with a backlight module is used to realize the visualization of the power. Its installation is simple and direct, and the cost is low. However, when the LED light source is directly displayed, its light is often more concentrated, and it is difficult to provide a uniform lighting effect, especially on a larger display panel; in addition, the brightness of the LED light source may be affected by the viewing angle and distance, resulting in different clarity of the power display when the user observes at different angles and distances, thereby reducing the use effect. Summary of the invention

[0004] The purpose of the utility model is to provide a battery pack power display structure, which solves the technical problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a battery pack power display structure, including a battery pack main body, characterized in that: a group of battery connection seats, a circuit board, four transparent covers and a button are fixedly installed and connected inside the battery pack main body, a number of batteries are inserted and connected between the battery connection seats, a power display light plate is fitly connected between any one of the batteries and the connection groove of the battery connection seat, a connection end is fixedly connected to the top of the button, and the connection end is connected to the upper surface of the circuit board, four display lights are fixedly installed on the upper surface of one side of the circuit board, and the light under the display lights shines into the interior of the transparent cover.

[0006] Optionally, the upper end of the button is plugged into a side of the circuit board away from the transparent cover.

[0007] Optionally, the button is made of an optical material such as acrylic resin, polycarbonate, epoxy resin and glass.

[0008] Optionally, the transparent cover is fixedly mounted on the lower surface of the circuit board, and the upper end of the transparent cover is correspondingly mounted on the lower surface of the display light.

[0009] Optionally, the transparent cover is specifically a bent shape that helps to refract the light source.

[0010] Optionally, a plurality of heat dissipation holes are provided through the surface of the battery pack body.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The utility model uses a button in the battery pack body. First, the power display light board in the battery connector detects and displays the current power of the battery, and transmits the power status to the circuit board. The circuit board controls the display light according to the detection status of the power display light board, and the display light displays the power status of the battery pack body. The display light feeds back the light source to the transparent cover, and the transparent cover refracts the light source of the power. The refraction can not only weaken the glare of the display light, but also provide a clearer display effect. Compared with the traditional backlight module, the transparent cover does not require an additional power supply, which reduces the energy consumption of the battery pack. At the same time, the high-efficiency refraction and transmission characteristics of the transparent cover also ensure the effective use of light, further improving the energy efficiency ratio of the power display, not only ensuring the effective transmission of light and the accuracy of the display effect, but also greatly improving the reliability of the battery pack power display and user experience, thereby ensuring the excellent use effect of the power display structure.

[0013] 2. The utility model utilizes the connection end of the button to penetrate and connect to the circuit board, so that the button can be conveniently and quickly installed and connected directly to the circuit board through the connection end, thereby ensuring the convenience of installation and removal, facilitating future maintenance operations, and further ensuring the excellent use effect of the power display structure.
