Description

Technical Field

[0001] This utility model relates to a fireworks switch bracket and a vehicle-mounted energy system, belonging to the technical field of vehicle-mounted energy systems. Background Technology

[0002] With the rapid development of electric and hybrid vehicles, the safety and reliability of onboard power systems (PACKs) are becoming increasingly critical. In onboard PACKs, pyrotechnic switches, as essential components ensuring the safety of the vehicle and passengers, are used to quickly cut off power in emergency situations and are typically indispensable parts of onboard PACK products. Pyrotechnic switches require mounting structures such as brackets to be installed and secured on the PACK product.

[0003] In existing technologies, the fixing structure used to fix pyrotechnic switches is usually a plastic shell structure, consisting of upper and lower shells, in the form of an upper and lower vertical structure. This has many technical shortcomings, such as: 1. It has high requirements for the height space of the application scene, and its structural space adaptability is poor; 2. The structure is relatively complex, consisting of at least two parts, and the assembly of the parts requires an additional installation process; 3. The manufacturing cost is high: it usually requires more than two sets of molds; 4. The overall cost per unit is high (including material costs and the total cost of each part). Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a pyrotechnic switch bracket and vehicle-mounted energy system.

[0005] To solve the above-mentioned technical problems, this utility model provides a pyrotechnic switch bracket, comprising: a bracket body, the bracket body including a recessed portion facing the front and copper busbar connecting portions located on both sides of the recessed portion;

[0006] The main body of the bracket also includes a base located at the bottom of the recess and the copper busbar connection part;

[0007] The base is provided with a first metal fastener for fixing the bracket itself;

[0008] The recessed portion is used to house the pyrotechnic switch;

[0009] The copper busbar connector has a built-in electrical output terminal for fixing the pyrotechnic switch and a second metal fastener for fixing the copper busbar.

[0010] The above technical solution can not only fix the pyrotechnic switch with a single bracket body, but also has high reliability. Only one set of molds is needed, reducing the cost of mold making.

[0011] Furthermore, the main body of the support adopts a horizontal structural layout.

[0012] The above technical solution effectively reduces the height by changing the pyrotechnic switch bracket to a horizontal structure, thus improving its adaptability to low-height spaces.

[0013] Furthermore, the base, the recess, and the copper busbar connection are integrally molded using an injection molding process.

[0014] The above technical solution, through the integrated base, recessed part and copper busbar connection part, allows the pyrotechnic switch bracket to only require one set of molds, thereby reducing mold opening costs, reducing product costs and improving installation efficiency, thus achieving cost reduction and efficiency improvement.

[0015] Furthermore, the first metal fastener is respectively located on the outside of the copper busbar connection portion on both sides of the recess.

[0016] In the above technical solution, the first metal fastener is used to fix the bracket and can resist the damage to the plastic caused by the high-strength preload of the bolt.

[0017] Furthermore, the top of the recess is provided with an extension integrally formed therewith.

[0018] The above-mentioned technical solution can expand the coverage of the pyrotechnic switch through the extension.

[0019] Furthermore, the bottom surface of the extension and the base are provided with several opposing buckles for assisting in fixing the pyrotechnic switch.

[0020] The above technical solution, by setting up several corresponding clips, can help fix the pyrotechnic switch, enabling rapid pre-installation of components and freeing the installer's hands.

[0021] Furthermore, the buckle located on the base is integrally formed with the base, and the buckle located on the extension is integrally formed with the extension.

[0022] The above technical solution uses buckles that are naturally formed from the base and extension of the main body of the bracket, eliminating the need for additional additions and manufacturing later, thus saving time and costs.

[0023] Furthermore, the first metal fastener is a metal bushing.

[0024] The above technical solution uses a metal bushing and bolts to fix the bracket, which is convenient and reliable.

[0025] Furthermore, the second metal fastener is a metal nut.

[0026] The above technical solution uses metal nuts and bolts to overlap and fix the copper busbar connection, and has sufficient metal strength, making it not easy to break.

[0027] Secondly, this utility model provides an on-board energy system, including the pyrotechnic switch bracket described in the first aspect.

[0028] The above technical solution can quickly cut off the power supply in an emergency.

[0029] The beneficial effects achieved by this utility model are:

[0030] Firstly, this utility model forms a support body through a base, a recessed part, and a copper busbar connecting part, which can not only fix the pyrotechnic switch, but also has high reliability. Only one mold is needed, reducing the cost of mold making.

[0031] Secondly, the pyrotechnic switch bracket used in the first aspect of the vehicle energy system can quickly cut off the power supply in an emergency. Attached Figure Description

[0042] The main body of the bracket also includes a base 3 located at the bottom of the recessed portion 1 and the copper busbar connection portion 2;

[0043] The base 3 is provided with a metal bushing 5 for fixing the bracket itself. The metal bushing 5 fixing parts are respectively located on the outside of the copper busbar connection on both sides of the recess, which is used to fix the bracket and resist the damage to the plastic by the high-strength pre-tightening force of the bolt.

[0044] The recess 1 is used to house the pyrotechnic switch 4;

[0045] like Figure 2 and Figure 4 As shown, the copper busbar connection part 2 has built-in electrical pins 8 for fixing the pyrotechnic switch and metal nuts 6 for fixing the copper busbar 13.

[0046] The base 3, the recessed part 1, and the copper busbar connecting part 2 are integrally formed by injection molding to form the main body of the bracket. The main body of the bracket can not only fix the pyrotechnic switch with high reliability, but also only requires one set of molds, thereby reducing mold opening costs, reducing product costs and improving installation efficiency, thus achieving cost reduction and efficiency improvement.

[0047] The main body of the bracket adopts a horizontal structure layout. By changing the pyrotechnic switch bracket to a horizontal structure, the height dimension is effectively reduced, which is conducive to adaptability to low-height spaces.
