Description

Technical Field

[0001] This utility model relates to the field of power supply top cover technology, specifically a power supply protective top cover. Background Technology

[0002] A power battery is a power source that provides power to tools, primarily referring to the batteries that power electric vehicles, electric trains, electric bicycles, and golf carts. Power batteries are a core component of new energy vehicles and an important direction for future energy transition.

[0003] Disconnecting power when a power source catches fire is a highly effective measure. In the event of a fire, disconnecting the power supply immediately prevents the fire from spreading and reduces the risk of explosion. Specifically, disconnecting the power reduces heat generation inside the battery, thereby slowing the spread and reducing the extent of the fire. Utility Model Content

[0004] The purpose of this utility model is to provide a protective cover for power sources to solve the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a power supply protective top cover, comprising a top cover body, with a connecting cap mounting seat fixed on each of the top two sides of the top of the top cover body, a connecting cap being fixedly mounted on the top of the connecting cap mounting seat by adhesive, an electrode rivet being mounted at the center of the connecting cap, and a rivet insertion hole penetrating the top cover body being provided at the center of the connecting cap mounting seat, the diameter of the rivet insertion hole being larger than the diameter of the electrode rivet, and a spring being mounted on the inner side of the connecting cap mounting seat, wherein the spring is in a compressed state after the connecting cap and the connecting cap mounting seat are combined.

[0006] Preferably, a spring limiting ring is fixed on the inner side of the connecting cap mounting base, and the spring is disposed between the spring limiting ring and the connecting cap mounting base.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] Please see Figure 1-3 In this embodiment of the utility model, a protective top cover for a power supply includes a top cover body 1. A connecting cap mounting base 4 is fixed to each of the top two sides of the top of the top cover body 1. A connecting cap 5 is fixedly mounted on the top of the connecting cap mounting base 4 using adhesive. An electrode rivet 6 is installed at the center of the connecting cap 5. A rivet insertion hole 10 penetrating the top cover body 1 is provided at the center of the connecting cap mounting base 4. The diameter of the rivet insertion hole 10 is larger than the diameter of the electrode rivet 6. A spring 8 is installed inside the connecting cap mounting base 4. After the connecting cap 5 and the connecting cap mounting base 4 are combined, the spring 8 is in a compressed state. When the power supply is damaged and its internal pressure increases to a certain extent, the spring 8 can push the connecting cap 5 upwards, causing the electrode rivet 6 fixed on the connecting cap 5 to separate from the inner core of the power supply, thereby achieving the effect of quickly cutting off the current. It also serves to relieve pressure on the power supply. After the connecting cap 5 is pushed upwards, the spring 8 can keep the connecting cap 5 in this state.

[0021] A spring limiting ring 9 is fixed on the inner side of the connecting cap mounting base 4. The spring 8 is located between the spring limiting ring 9 and the connecting cap mounting base 4. The spring limiting ring 9 is used for the accurate installation of the spring 8 and can also make the spring 8 more stable after installation.

[0022] A groove 7 is provided on the outer side of the connector cap mounting base 4. The width of the groove 7 is greater than the thickness of the connector cap 5, which is used to facilitate the filling of adhesive.

[0023] A positioning ring 12 is fixed on the inner bottom of the connecting cap 5. The positioning ring 12 and the spring limiting ring 9 are in clearance fit. The positioning ring 12 is used to stabilize the installation of the connecting cap 5.

[0024] An insulating component 11 is provided between the connecting cap 5 and the electrode rivet 6 to provide insulation.

[0025] An explosion-proof plate mounting slot 2 is fixed at the top center of the main body 1, and an explosion-proof plate 3 is installed on the explosion-proof plate mounting slot 2.

[0026] The working principle of this utility model is as follows: when the power supply is damaged and its internal pressure increases to a certain extent, it can cooperate with the spring 8 to push the connecting cap 5 upward, so that the electrode rivet 6 fixed on the connecting cap 5 is separated from the inner core of the power supply, thereby achieving the effect of quickly cutting off the current. At the same time, it can also relieve the pressure of the power supply. After the connecting cap 5 is pushed upward, the spring 8 can keep the connecting cap 5 in this state.

[0027] A spring limiting ring 9 is fixed on the inner side of the connecting cap mounting base 4. The spring limiting ring 9 is used for the accurate installation of the spring 8 and can also make the spring 8 more stable after installation.

[0028] A groove 7 is provided on the outer side of the connecting cap mounting base 4 to facilitate the filling of adhesive.
