Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness installation technology, and in particular to an automotive wiring harness fixing bracket assembly. Background Technology

[0002] With the continuous development of the automotive industry, the use of new energy vehicles is becoming increasingly widespread; consequently, the demand for wiring harnesses in new energy vehicles is growing, and the safety and reliability of wiring harnesses directly affect the overall vehicle quality. As a carrier of current transmission, wiring harnesses require reliable fixation and appropriate protection to prevent damage from various sharp sheet metal and other components inside the vehicle. In traditional technology, wiring harnesses are usually fixed using cable ties or pipe clamps. However, common cable ties have low strength and are easily pulled out when fixed in the engine compartment, especially in vibration areas, leading to wear and tear between the wiring harness and equipment in the engine compartment. With the maturity of technology, the combination of rubber components and metal brackets has emerged. Although it can provide better protection and shock absorption, its assembly steps are complex, wiring harness assembly is difficult, and manpower and resources are wasted. Moreover, the rubber components are not securely fixed and are prone to displacement under long-term stress from the wiring harness, or even detach from the metal bracket, causing wear and tear on the wiring harness, all of which pose safety hazards. In addition, the current fixing scheme for metal brackets mostly uses nut connections, which not only takes a long time to assemble but also hinders the reduction of vehicle weight. Utility Model Content

[0003] To address the shortcomings in the aforementioned background technology, this utility model proposes an easy-to-install automotive wiring harness fixing bracket assembly, which solves the problems of unreliable fixing of automotive wiring harnesses using cable ties or easy displacement when using rubber parts for fixing.

[0004] The technical solution of this utility model is achieved as follows: a convenient automotive wiring harness fixing bracket assembly includes a rubber ring for cooperating with the wiring harness, a bracket on the rubber ring, a cable tie on the bracket for fastening the rubber ring to the wiring harness, and a retaining spring on the bracket.

[0005] Furthermore, the rubber ring is provided with at least one wire-passing hole and an opening groove communicating with the wire-passing hole, and the wire-passing hole is provided with a raised rib.

[0006] Furthermore, the rubber ring is provided with a limiting member that cooperates with the bracket. The limiting member includes two symmetrically arranged limiting bosses, and the limiting bosses and the rubber ring are an integral structure.

[0007] Furthermore, the limiting boss is provided with a groove, which is located on one side of the opening groove.

[0008] Furthermore, the bracket includes an open bracket body, with cable tie holes on both sides of the bracket body for cooperating with cable ties, and mounting holes on the bracket body.

[0009] Furthermore, the support body is provided with limiting ribs that cooperate with the limiting member, and the limiting ribs are L-shaped. The support body is also provided with anti-rotation ribs.

[0010] Furthermore, the retaining ring includes a bent portion that engages with the bracket, and the bent portion is provided with a through square groove corresponding to the mounting hole.

[0011] Furthermore, the curved portion is provided with a reverse tooth structure that engages with the sheet metal studs on the vehicle body, and the reverse tooth structure is located within the through square groove.

[0012] The beneficial effects of this utility model are as follows: This utility model, through the cooperation of a bracket, rubber ring, snap ring, and cable ties, can save assembly time, reduce part weight, and improve product reliability while fixing and protecting the wire harness. The open-shaped bracket body and the open groove of the rubber ring fit together, eliminating the need for assembly sequence, facilitating wire harness insertion, and increasing assembly efficiency. The protruding rib structure inside the wire passage hole of the rubber ring prevents wire harness movement. The rubber ring is placed on the inner side of the bracket, and the limiting bosses and grooves on both sides of the rubber ring cooperate with the limiting rib structures on both sides of the bracket body, and are secured with cable ties to achieve the function of preventing displacement and detachment of the rubber ring.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-4 , Figure 9 , Figure 10 As shown in Embodiment 1, an easy-to-install automotive wiring harness fixing bracket assembly includes a rubber ring 2 for mating with the wiring harness 5, a bracket 1 on the rubber ring 2, a cable tie 6 on the bracket 1 for securing the rubber ring 2 to the wiring harness 5, and a retaining spring 3 on the bracket 1. The cooperation of the bracket 1, rubber ring 2, retaining spring 3, and cable tie 6 not only fixes and protects the wiring harness 5, but also saves assembly time, reduces component weight, and improves product reliability.

[0027] In specific use, the rubber ring 2 and the bracket 1 are used in sequence with the wire harness 5 to be fixed. Then, the bracket 1 and the coil 2 are further tightened by the cable tie 6. The retaining spring 3 can be installed into the bracket 1 at any time. Finally, the bracket 1 and the retaining spring 3 are installed on the body sheet metal 4 to realize the fixed assembly of the automotive wire harness.

[0028] like Figure 4 and Figure 6As shown in Embodiment 2, an easily installable automotive wiring harness fixing bracket assembly differs from the technical solution of Embodiment 1 in that the rubber ring 2 has at least one wire passage hole 24 and an opening groove 22 communicating with the wire passage hole 24, and a rib 25 is provided inside the wire passage hole 24. The opening groove 22 cooperates with the wire passage hole 24 to facilitate the installation of the wiring harness 5, and the rib 25 structure inside the wire passage hole 24 of the rubber ring 2 can prevent the wiring harness 5 from moving.

[0029] In this embodiment, the rubber ring 2 is provided with a limiting member that cooperates with the bracket 1. The bracket 1 is installed on the rubber ring 2 through the limiting member, which can further stabilize the installation and cooperation between the rubber ring 2 and the bracket 1, and realize the function of preventing the rubber ring 2 from shifting or falling off.

[0030] In a preferred embodiment, the limiting member includes two symmetrically arranged limiting bosses 23, which are integrally formed with the rubber ring 2. Each limiting boss has a groove 21 located on one side of the opening groove 22. The limiting bosses 23 are used to cooperate with the bracket 1. The limiting bosses 23 are used to restrict the bracket 1 onto the rubber ring 2, preventing the rubber ring 2 from shifting. The limiting bosses 23 have two symmetrically arranged grooves 21 located on one side of the opening groove 22. When the rubber ring 2 has two wire holes 24 and an opening groove 22, the groove 21 is located between the two opening grooves 22.

[0031] In another preferred embodiment, the limiting member is a limiting groove provided on the rubber ring 2. The limiting groove cooperates with the bracket 1 to fix the bracket 1 on the rubber ring 2, so that the bracket 1 and the rubber ring 2 form a constraint structure for the wire harness. Preferably, the limiting groove and the opening groove 22 are arranged in parallel.

[0032] All other structures are the same as in Example 1.

[0033] like Figure 4 and Figure 5As shown in Embodiment 3, a convenient automotive wiring harness fixing bracket assembly differs from the technical solution of Embodiment 1 in that the bracket includes an open bracket body 15. The bracket body 15 has cable tie holes 12 on both sides for mates with cable ties 6, and mounting holes 14 on the bracket body 15. Preferably, the bracket body 15 includes a C-shaped bend, which conforms to the curvature of the rubber ring 2, and the thickness of the C-shaped bend is equal to the height of the limiting boss 23. A positioning plate 16 is provided at the end of the C-shaped bend 15, and the mounting holes 14 are located on the positioning plate 16. The width of the positioning plate 16 is selected according to actual needs. The bracket body 15 has a limiting rib 11, which is an L-shaped structure. One end of the L-shaped structure is connected to the middle of the bracket body 15, and the other end of the L-shaped structure faces the opening of the bracket body 15, so that the L-shaped structure and the bracket body 15 combine to form a cross-shaped structure. The bracket 1 has an anti-corrosion layer. The anti-corrosion layer is preferably electrophoretic black paint, which can increase the service life of the support 1.

[0034] In this embodiment, the bracket body 15 is provided with an anti-rotation rib 13. The anti-rotation structure formed by the bracket body 15 and the anti-rotation rib 13 is set on one side of the mounting hole to realize the anti-rotation function of the bracket 1 when it is installed on the vehicle body.

[0035] Specifically, the anti-rotation rib 13 is mounted on the positioning plate 16 and mates with the sheet metal anti-rotation groove 42 on the body sheet metal 4. The positioning plate 16 and the bracket body 15 are integrally formed. A through hole is provided at the connection between the positioning plate 16 and the bracket body 15, and a reinforcing rib is provided on the through hole for connecting the positioning plate 16 and the bracket body 15. The connection between the positioning plate 16 and the bracket body 15 is an arc-shaped connection, and the bracket body 15 and the positioning plate 16 are integrally stamped and bent from thin metal sheets.

[0036] All other structures are the same as in Example 2.

[0037] like Figures 7-9 As shown in Embodiment 4, a convenient automotive wiring harness fixing bracket assembly, in a preferred embodiment, includes a bent portion 25 that engages with the bracket 1. The bent portion 25 has a through square groove 32 corresponding to the mounting hole 14. The bent portion is preferably a U-shaped bent portion. The bent portion has a reverse tooth structure that engages with the sheet metal studs on the vehicle body, and the reverse tooth structure is located within the through square groove. The mounting hole 14 of the bracket 1 coincides with the through square groove 32 of the metal retaining spring 3. The retaining spring 3 has two inwardly curved reverse tooth structures, which serve to limit and fix the connection, engaging with the threads of the sheet metal studs 4. This eliminates the need for a nut assembly while ensuring reliable connection and preventing the bracket 1 from falling off.

[0038] In another preferred embodiment, the retaining ring 3 includes a plate that snaps into the bracket 1. The plate has a reverse tooth structure that engages with the sheet metal studs for locking. The reverse tooth structure corresponds to the mounting hole. The bracket 1 is installed on the body sheet metal through the mounting hole and the reverse tooth structure that engages with the mounting hole. The installation method is simple, the fixing effect is good, and there is no need to worry about bolt torque attenuation or nut falling off.

[0039] The specific structure is as follows: the bracket 1 has limiting ribs 11 on both sides, and the rubber ring 2 has limiting protrusions 23 on both sides to prevent the rubber ring 2 from shifting or falling out under force, thus providing a good protection effect for the high-voltage wire harness 5; at the same time, the use of cable ties 6 for fixing can accommodate various specifications of wire harness 5 with appropriate tightness; both the rubber ring 2 and the bracket 1 are open designs, which facilitates the assembly of the wire harness 5; the bracket 1 is used in conjunction with the snap ring 3 to directly snap into the stud on the vehicle without the need for nut connection, which reduces the weight of the whole vehicle and makes assembly very convenient, saving materials and labor time.

[0040] All other structures are the same as in Example 3.

Limiting ribs are provided on both sides of the C-shaped bend structure to prevent the rubber ring 2 from shifting axially under force. The rubber ring 2 has bosses and grooves on both sides to limit its movement against the bracket 1 and prevent it from shifting. The protruding rib structure inside the wire hole of the rubber ring 2 increases the friction of the wire harness and prevents the wire harness from shifting. The C-shaped bend structure of the bracket 1 and the open groove structure of the rubber ring 2 help improve the assembly efficiency of the wire harness.

[0042] like Figure 5 and Figure 7 As shown, the device includes a bracket 1 and a retaining ring 3. The U-shaped bending structure of the retaining ring 3 is inserted into the bracket 1, so that the through square groove and the mounting hole coincide with each other, and the reverse tooth structure is inserted into the mounting hole, thereby realizing the assembly and fixation of the bracket 1 and the retaining ring 3.

[0043] like Figure 5 , Figure 7 , Figure 8 As shown, the mounting hole of the bracket 1 and the reverse tooth structure of the snap ring 3 are inserted into the stud of the body sheet metal 4. The reverse tooth structure and the thread of the stud are engaged with each other, eliminating the need for nut connection and realizing the assembly and fixation of the bracket and the body sheet metal 4.

[0044] like Figure 5 and Figure 8As shown, the bracket 1 is equipped with an anti-rotation rib structure, which is fitted into the groove of the body sheet metal 4 to achieve the anti-rotation function of the bracket. The bracket 1 has cable tie holes at both ends of the bracket body for use with cable ties for bundling. The tightness is adjustable, and it can realize the assembly and fixing of various wire diameters.

[0045] like Figure 5 As shown, the bracket 1 is a C-shaped structure formed by integral stamping and bending of a thin metal sheet, with an anti-corrosion coating on the surface, providing high strength and corrosion resistance. The mounting holes of the bracket 1 can be configured as circular or oblong holes of different sizes to accommodate different specifications of body panel studs, depending on the installation requirements.

[0046] like Figure 6 As shown, the rubber ring 2 is made of rubber and is integrally injection molded, which has high shock resistance and aging resistance.

[0047] like Figure 7 As shown, the retaining spring 2 is a U-shaped structure formed by integral stamping and bending of a thin metal sheet, with an anti-corrosion coating on the surface, providing high strength and corrosion resistance. The reverse tooth structure on the through square groove of the retaining spring 2 engages with the stud threads of the body sheet metal 4, achieving both fixation and anti-retraction functions.

[0048] like Figure 7 As shown, the metal pieces on the through square groove of the snap ring 3 can be set with different sizes and spacings according to the requirements of the installation environment, so as to adapt to different specifications of body sheet metal studs.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
