[0002] Charging rack plates are plates installed on a charging rack that play a crucial role in battery charging. They are an important component of the battery charging system, facilitating rapid charging of the battery and improving its charging efficiency.

[0003] The charging rack plates need to be connected to the positive and negative terminals of the battery for charging. However, traditional charging rack plates do not have a proper overvoltage protection mechanism, which causes excessive pressure between the charging rack plates and the positive and negative terminals of the battery during connection. This can easily lead to damage to the positive and negative terminals of the battery and the plates, thus affecting the later use of the battery and the plates. In order to solve the above problems, there is an urgent need for a limiting device to prevent overvoltage of the charging rack plates. Utility Model Content

[0004] The purpose of this utility model is to provide a limiting device for overvoltage prevention of charging rack plates. In order to solve the problem that the charging rack plates need to be connected to the positive and negative terminals of the battery for charging, but the traditional charging rack plates do not have a perfect overvoltage prevention mechanism, which causes excessive compression between the charging rack plates and the positive and negative terminals of the battery when connected, which can easily lead to damage to the positive and negative terminals of the battery and the plates, thus affecting the later use of the battery and the plates. Therefore, a limiting device for overvoltage prevention of charging rack plates is proposed.

[0005] To achieve the above objectives, a limiting device for preventing overvoltage of a charging rack electrode plate is provided, comprising: a support column and an electrode plate body, a flat plate is fixedly installed on the outer wall of the upper and lower ends of the support column, a limiting component is provided on the flat plate, a horizontal plate is fixedly installed on the upper surface of the flat plate, and an overvoltage prevention component is provided on the outer wall of the horizontal plate. The overvoltage protection assembly includes a side plate, which is fixedly installed on the outer walls of both sides of the electrode plate body. A spring is fixedly installed on the outer wall of the side plate. A groove is provided on the outer wall of the horizontal plate, and the other end of the spring is fixedly installed on the inner wall of the groove.

[0006] According to the aforementioned overvoltage prevention limiting device for charging rack plates, the limiting component includes a push plate and a threaded rod, and a spring rod is fixedly installed on the outer wall of the push plate.

[0007] According to the aforementioned overvoltage prevention limiting device for charging rack plates, a clamping plate is fixedly installed at the other end of the spring rod, and a connecting rod is fixedly installed on the lower surface of the push plate.

[0008] According to the aforementioned overvoltage protection limiting device for charging rack plates, a connecting block is fixedly installed at the bottom end of the connecting rod, and a threaded hole is provided on the outer wall of the connecting block.

[0009] According to the aforementioned overvoltage protection limiting device for charging rack plates, the threaded rod is threadedly installed on the inner wall of the threaded hole, and a knob is fixedly installed at one end of the threaded rod.

[0010] According to the aforementioned overvoltage protection limiting device for charging rack plates, a travel groove is provided on the upper surface of the plate, and the inner wall of the travel groove is slidably connected to the connecting rod.

[0011] According to the aforementioned overvoltage protection limiting device for charging rack plates, the flat plate has a threaded rod mounting groove inside, and the threaded rod is rotatably mounted on the inner wall of the threaded rod mounting groove.

[0012] According to the aforementioned overvoltage protection limiting device for charging rack plates, a battery placement slot is provided on the upper surface of the flat plate, and a heat dissipation slot is provided at the bottom of the battery placement slot.

[0013] The above-mentioned solution has the following beneficial effects: In this invention, by incorporating an overvoltage protection component and a limiting component, the limiting component effectively restricts the battery, securing it during charging and preventing the positive and negative terminals from detaching from the plates. Simultaneously, overvoltage protection is applied to the plates and the positive and negative terminals to prevent excessive pressure during clamping, which could damage the terminals and plates. This also prevents short circuits during later use, enhancing the safety of battery charging and resulting in superior performance.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0019] Reference Figure 1-4 This utility model embodiment provides a limiting device for overvoltage prevention of charging rack plates, which includes: a support column 1 and a plate body 6. A flat plate 2 is fixedly installed on the outer wall of the upper and lower ends of the support column 1. The flat plate 2 is used to place the storage battery. A limiting component 8 is provided on the flat plate 2. A horizontal plate 5 is fixedly installed on the upper surface of the flat plate 2. An overvoltage prevention component 7 is provided on the outer wall of the horizontal plate 5. The overpressure prevention assembly 7 includes a side plate 72, which is used to install a spring 73. The side plate 72 is fixedly installed on the outer walls of both sides of the electrode body 6. The spring 73 is fixedly installed on the outer wall of the side plate 72. The elastic force of the spring 73 is used to prevent clamping overpressure. A groove 71 is provided on the outer wall of the horizontal plate 5. The groove 71 is used to provide the compression space for the spring 73. The other end of the spring 73 is fixedly installed on the inner wall of the groove 71.

[0020] The limiting assembly 8 includes a push plate 86 and a threaded rod 82. The push plate 86 indirectly clamps the battery. A spring rod 88 is fixedly installed on the outer wall of the push plate 86. The spring force of the spring rod 88 clamps the battery to prevent over-clamping. A clamping plate 87 is fixedly installed on the other end of the spring rod 88. The clamping plate 87 is used to directly clamp the battery. A connecting rod 84 is fixedly installed on the lower surface of the push plate 86. The connecting rod 84 connects the connecting block 83 to the push plate 86. A connecting block 83 is fixedly installed at the bottom end of the connecting rod 84. A threaded hole 85 is opened on the outer wall of the connecting block 83. The connecting block 83 is connected to the push plate 86 through the threaded hole 85. The threaded rod 82 is threaded, and the connecting block 83 is moved horizontally by driving the threaded rod 82 to rotate. The threaded rod 82 is threadedly installed on the inner wall of the threaded hole 85. A knob 81 is fixedly installed at one end of the threaded rod 82. A stroke groove is opened on the upper surface of the plate 2. The cooperation between the stroke groove and the connecting rod 84 serves as a limiting part for the connecting block 83 to prevent the connecting block 83 from moving on the threaded rod 82. The inner wall of the stroke groove is slidably connected to the connecting rod 84. A threaded rod mounting groove is opened inside the plate 2. The threaded rod 82 is rotatably installed on the inner wall of the threaded rod mounting groove. The end of the threaded rod 82 with the knob 81 installed passes through a through hole opened on one side of the plate 2.

[0021] The upper surface of the tablet 2 is provided with a battery placement slot 3, and the bottom of the battery placement slot 3 is provided with a heat dissipation slot 4. The heat dissipation slot 4 is used to increase the contact area between the battery and the outside world, thereby improving the heat dissipation efficiency.

[0022] Working principle: First, place the battery into the battery placement slot 3, with the positive and negative terminals facing the plate body 6. Then, rotate the knob 81. The knob 81 drives the threaded rod 82 to rotate, and at the same time, the threaded rod 82 drives the connecting block 83 to move on its outer wall. The connecting block 83 drives the push plate 86 to move through the connecting rod 84. The push plate 86 drives the spring rod 88 and the clamping plate 87 to move synchronously. The clamping plate 87 then pushes the battery to move. The spring rod 88 is slightly compressed, and the clamping plate 87 pushes the battery to the plate body 6, so that the positive and negative terminals of the battery contact the plate body 6. Next, the positive and negative terminals of the battery press against the plate body 6. After being pressed, the plate body 6 is displaced. The side plates 72 on both sides of the plate body 6 press against the spring 73, compressing it. Then, the knob 81 is continuously rotated until both the spring rod 88 and the spring 73 are in a compressed state. The push plate 86 does not directly clamp the battery body. Instead, it clamps the battery by the elastic force generated by the compression of the spring rod 88. The elastic force generated by the compression of the spring rod 88 and the spring 73 limits the clamping of the battery, thereby avoiding excessive clamping force.

[0023] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
