Description

Technical Field

[0001] The utility model relates to the technical field of vehicle frames, in particular to a grounding bolt structure for an aluminum vehicle frame. Background Art

[0002] Currently, automotive electronic and electrical systems utilize a single-wire system, typically using a negative grounding method. This involves connecting the negative terminal of the battery to the vehicle body, and the negative terminal of the electronic device to the vehicle body to form a circuit. This reduces wiring costs and minimizes the possibility of circuit failure. Existing aluminum frame grounding systems connect the grounding to the vehicle frame through welding. This method is complex, requires secondary processing, and has poor maintainability. Furthermore, this structure cannot prevent the grounding from rotating after installation.

[0003] In the prior art, bolts are also used as grounding bolts, which are connected by bolts. For example, the utility model patent with application number: 201520385318.6 discloses a grounding bolt that is connected to the frame by a single bolt. The grounding bolt is also not anti-rotation and the connection is not tight enough. Utility Model Content

[0010] Furthermore, the rivet sleeve includes: a fixed plate connecting tube and a connecting block, the connecting block and the fixed plate are connected via the connecting tube, the connecting tube and the fixed plate are provided with through holes for the stud to pass through, and the connecting block is provided with a thread that cooperates with the stud.

[0011] The benefit of adopting the above technical solution is that the connection block is provided for connecting bolts, the bolts pass through the connection tube, and the lower side of the fixing plate is tightly fixed to the frame.

[0012] Furthermore, the wiring harness terminal is provided with a terminal portion, and the terminal portion includes a bottom plate and connecting portions provided on both sides of the bottom plate, and the connecting portions are bent toward the upper side.

[0013] Furthermore, the wiring harness terminal is an integrally formed structure, the anti-rotation block is bent downward, and the side surface of the anti-rotation block contacts the side surface of the rivet sleeve.

[0014] The benefit of adopting the above technical solution is that the one-piece molded structure is easy to process and improves service life. The bending parts set on both sides are used to connect with the wiring harness, which is convenient for installation and maintenance. The setting of the anti-rotation block can prevent the wiring harness terminal from rotating, preventing the wiring harness terminal from rotating and causing the wiring harness to be entangled, resulting in poor contact.

[0015] Furthermore, a mounting gasket is provided between the locking nut and the wiring harness terminal, and anti-slip protrusions are provided on both sides of the mounting gasket.

[0018] The benefit of adopting the above technical solution is that the polygonal structural setting can effectively prevent the connecting tube from rotating after being matched with the riveted plate, thereby facilitating installation.

[0019] Furthermore, the connecting tube extends into the riveted plate, and the stud is pulled upward, so that the lower end of the connecting tube protrudes outward, and the connecting tube is connected and fixed to the riveted plate.

[0020] The benefit of adopting the above technical solution is that the connecting tube and the riveted plate are riveted together by riveting, ensuring that the connecting tube and the riveted plate are installed and fixed, and at the same time ensuring that the connecting tube and the riveted plate fit tightly, ensuring the electrical function of the grounding.

[0021] Furthermore, the fixing plate is a polygonal structure.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings.

[0031] like Figure 1-4 As shown, the utility model discloses an aluminum frame grounding bolt structure, comprising:

[0032] A rivet sleeve 1 is provided with a stud 2 inside, and the end of the stud 2 is connected to the rivet sleeve 1;

[0033] The wiring harness terminal 3 is provided with a ring portion connected to the stud 2, and the wiring harness terminal 3 is provided with an anti-rotation block 31, and the anti-rotation block 31 abuts against the rivet sleeve 1;

[0034] The locking nut 4 is provided on the upper side of the wiring harness terminal 3 and is used to fasten the wiring harness terminal 3 .

[0035] The advantages of adopting the above technical solution are simple structure, easy installation, safety and reliability, tight connection and anti-rotation function.

[0036] In some embodiments, the rivet sleeve 1 includes a fixing plate 11, a connecting tube 12, and a connecting block 13. The connecting block 13 is connected to the fixing plate 11 via the connecting tube 12. The connecting tube 12 and the fixing plate 11 are provided with through holes for the stud 2 to pass through. The connecting block 13 is internally provided with threads that cooperate with the stud 2. The lower surface of the fixing plate 11 is flat and is used to be tightly attached to the vehicle frame. The connecting block 13 is provided for connecting bolts. The bolts pass through the connecting tube 12, and the lower side of the fixing plate 11 is tightly fixed to the vehicle frame.

[0037] In some embodiments, the wiring harness terminal 3 is provided with a terminal portion, which includes a base plate 32 and a connecting portion 33 provided on both sides of the base plate 32. The connecting portion 33 is bent upward. When connection is required, the wiring harness only needs to be placed on the base plate 32, and then the connecting portion 33 is bent to complete the connection between the wiring harness and the terminal. The contact is good and the installation is convenient.

[0038] Furthermore, the wiring harness terminal 3 is an integrally formed structure, and the anti-rotation block 31 is bent downward, with the side of the anti-rotation block 31 contacting the side of the rivet sleeve 1. The integrally formed structure facilitates processing and improves service life. The bent portions on both sides are used to connect with the wiring harness, facilitating installation and maintenance. The anti-rotation block 31 can prevent the wiring harness terminal 3 from rotating, preventing the wiring harness from being entangled and causing poor contact.

[0039] In some embodiments, a mounting gasket 5 is provided between the locking nut 4 and the wiring harness terminal 3, and anti-slip protrusions are provided on both sides of the mounting gasket 5. The setting of the mounting gasket 5 enables the locking nut 4 to be installed firmly, prevents the nut from loosening, and extends the service life.

[0040] In some embodiments, the rivet sleeve 1 is connected to a vehicle frame, which is provided with a riveted plate 6 for connection. The connecting tube 12 has a polygonal structure, and the riveted plate 6 is provided with a through hole that matches the connecting tube 12. The cross-section of the connecting tube 12 can be hexagonal, and the riveted plate 6 is provided with a hexagonal hole that matches the connecting tube 12. After the connecting tube 12 is connected to the riveted plate 6, it can effectively prevent rotation, ensuring that the connecting tube 12 and the riveted plate 6 are tightly connected. The polygonal structure can effectively prevent the connecting tube 12 from rotating after being matched with the riveted plate 6, facilitating installation.

[0041] Furthermore, the connecting tube 12 is extended into the riveted plate 6, and the stud 2 is pulled upward using a rivet pliers, so that the lower end of the connecting tube 12 protrudes outward and deforms, connecting and fixing the connecting tube 12 to the riveted plate 6, ensuring that the connecting tube 12 fits tightly to the riveted plate 6 and ensuring the electrical function of the grounding.

[0042] In some embodiments, the fixing plate 11 is a polygonal structure. The polygonal structure can allow the anti-rotation block 31 to have multiple directions, which is convenient for routing in multiple directions and greatly facilitates installation.

[0043] During the assembly process, first extend the connecting tube 12 into the riveted plate 6, and pull the bolt with the rivet pliers. At this time, the connecting tube 12 is deformed outward, and the deformed connecting tube 12 cooperates with the fixing plate 11 to achieve bolt fixation. Then install the wiring terminal 3 on the bolt, set the position of the anti-rotation block 31 according to the wiring direction, and then install the installation gasket 5 and the locking nut 4 to complete the installation.

[0044] It has the following advantages:

[0045] 1. Simple structure and easy installation;

[0046] 2. Safe and reliable, saves operation time and improves efficiency;

[0047] 3. Flexible structure, adaptable to various models;

[0048] 4. It can realize grounding to prevent rotation.

[0049] For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
