Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle battery technology, specifically a fuse box for an automotive battery pack. Background Technology

[0002] New energy vehicles have experienced rapid development due to their high energy efficiency and environmental friendliness. They typically operate under high-power vehicle electrical systems, with voltages exceeding 700VDC and currents reaching 400A, posing significant challenges to the design of high-voltage power distribution systems and the selection of high-voltage components. Considering the complexity of vehicle space, architecture, and cost, the industry widely adopts centralized high-voltage electrical system architectures for power distribution. High-voltage power supplies directly enter the high-voltage distribution box and are then distributed to high-voltage electrical products according to system needs. This places high demands on ensuring the safety of the entire high-voltage system and its individual electrical equipment, as well as system insulation, electromagnetic interference and shielding, sealing, and vibration resistance.

[0003] The prior art document, "A Fuse Box for an Automotive Battery Pack," (CN222394766U), features a separate fuse box that is directly mounted on the vehicle frame. This design is simple in structure and utilizes an anti-misalignment groove in the mounting cavity to facilitate the installation of limit switches. The anti-misalignment groove also includes a spring-loaded tab for quick removal of the limit switches. Currently, the penetration rate of new energy vehicles in the market is continuously increasing, and new energy vehicle battery packs are pursuing higher energy density. To accommodate more battery modules, the design space of the power distribution system is compressed. This utility model effectively reduces design space, satisfies the requirement for limit switch fixing, reduces costs, facilitates repairs, and shortens labor time.

[0004] However, fuse boxes are often fixed with six to eight bolts during use, requiring special tools for installation, resulting in low assembly efficiency and inconvenience to users, and can no longer meet their needs. Utility Model Content

[0020] The utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are only descriptive and are not limiting of the scope of protection of this utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a fuse box for an automotive battery pack, including a mounting base 1, which is used to set corresponding components. The mounting base 1 has an internal cavity and a box body 2, which is a fuse box. Positioning protrusions 3 are fixedly set at the four corners of the bottom of the box body 2, and the positioning protrusions 3 play a positioning role. Grooves 4 are set at both sides of the top of the mounting base 1, and the grooves 4 are used to set corresponding components. The front and rear surfaces of the grooves 4 are movably set with swing rods 5 through a rotating shaft. The swing rods 5 are used to set limit ball 6. The top of the swing rods 5 is fixedly set with limit ball 6, and the limit ball 6 plays a limiting role. Pins 7 are set at the front and rear ends of the top of both sides of the mounting base 1, and the pins 7 can limit the swing rods 5. The pins 7 are fixedly connected to the mounting base 1 by springs.

[0022] Furthermore, a lid 8 is movably provided on the top of the box body 2, wherein the lid 8 serves to seal and prevent dust.

[0023] Furthermore, the bottom of the positioning protrusion 3 extends into the interior of the mounting base 1, and the positioning protrusion 3 is engaged with the mounting base 1, wherein the positioning protrusion 3 plays a positioning role.

[0024] Furthermore, the top of the swing arm 5 passes through the groove 4 and extends to the outside of the mounting base 1, wherein the swing arm 5 is able to drive the limiting ball 6 to move.

[0025] Furthermore, the two limiting balls 6 extend into the interior of the box body 2 on opposite sides, and the limiting balls 6 engage with the box body 2. The limiting balls 6 serve to engage, and the side of the box body 2 is provided with positioning grooves that match the limiting balls 6.

[0026] Furthermore, each of the two swing rods 5 has a support spring 9 fixedly installed on its opposite side, and the opposite side of each of the two support springs 9 is fixedly connected to the inner wall of the groove 4. The support spring 9 is able to swing the swing rod 5.

[0027] Furthermore, the two pins 7 each penetrate the mounting base 1 on opposite sides and extend into the interior of the swing rod 5. The pins 7 are engaged with the swing rod 5, and the pins 7 are movably connected to the mounting base 1. The pins 7 can limit the swing rod 5.

[0028] This automotive battery pack fuse box achieves rapid positioning and installation of the box body 2 through the clever arrangement of components such as the swing rod 5, pin 7, limit ball 6, and support spring 9. Its specific working principle is as follows:

[0029] Figure 3 The central support spring 9 is in a tensioned state, the limiting ball 6 is partially embedded in the positioning groove on the box 2, and the pin 7 limits the swing rod 5 at the bottom notch under the action of the spring, maintaining the stability of the entire positioning and installation structure.

[0030] During disassembly, simply pull the pin 7 outward to release the limit on the swing rod 5. At this time, the support spring 9 pulls the swing rod 5 under the elastic action, causing the limit ball 6 to leave the positioning groove, thereby releasing the limit.

[0031] Based on the above work process, we can conclude that:

[0032] The fuse box of this car battery pack, through the setting of a swing rod 5, a pin 7, a limit ball 6, and a support spring 9, enables the device to be quickly positioned and installed in the box body 2 during use, thereby reducing the user's installation time, improving the user's assembly efficiency, bringing convenience to the user, improving the practicality of the device, and meeting the user's needs.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
