Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to a high-strength, impact-resistant bracket structure for wiring harnesses in new energy vehicles. Background Technology

[0002] In the power system of new energy vehicles, wiring harnesses are a carrier of electrical energy transmission. There are many wiring harnesses near the chassis of the car. If a large number of wiring harnesses are randomly distributed near the chassis, they will appear messy. Furthermore, a large number of wiring harnesses are prone to friction with other parts, causing scratches and electrical circuit faults. Therefore, wiring harnesses usually need a bracket structure for positioning and fixing to ensure stable power transmission.

[0003] Currently, wiring harness brackets used in the new energy vehicle field are mainly divided into two categories: metal brackets and plastic brackets. Metal brackets can withstand large external impact loads, but their plasticity is poor. The sharp edges and corners of metal brackets caused by collision deformation are very easy to rub against the surface of high-voltage wiring harnesses, thereby scratching the wiring harnesses and reducing the operational safety of new energy vehicles. On the other hand, although plastic brackets are highly plastic, the toughness and impact resistance of plastic materials themselves are generally average. They are difficult to withstand the continuous impact of road gravel for a long time, and are prone to problems such as bracket cracking and damage, and cannot provide stable support and protection for wiring harnesses.

[0004] In summary, neither existing metal brackets nor plastic brackets can simultaneously meet the requirements of impact resistance, high strength, and protection for wiring harnesses, making them unsuitable for the complex operating conditions of wiring harnesses in new energy vehicle chassis. Therefore, there is an urgent need for a wiring harness bracket that can solve the above-mentioned defects in order to improve the operational safety and stability of wiring harnesses in new energy vehicles. Utility Model Content

[0005] To improve the operational safety and stability of wiring harnesses in new energy vehicles, this application provides a high-strength, impact-resistant support structure for wiring harnesses in new energy vehicles.

[0006] This application provides a high-strength, impact-resistant bracket structure for wiring harnesses in new energy vehicles, employing the following technical solution: A high-strength, impact-resistant bracket structure for wiring harnesses in new energy vehicles includes a bracket body with a cavity for placing the wiring harness. The bracket body includes a base layer formed by hot pressing of a composite material. The outer surface of the base layer is covered with a wrapping layer, which is integrally wrapped around the base layer by injection molding. The bracket body has multiple through holes, and fixing components for fixing the wiring harness are commonly arranged in the multiple through holes distributed along the width direction of the bracket body.

[0007] By adopting the above technical solution, during the production of the bracket body, the composite material is first hot-pressed to form a base layer, and then the base layer is fixed to an injection molding machine for secondary injection molding, so that the wrapping layer is integrally wrapped around the base layer, forming a double-layer composite bracket body. This bracket has higher strength and impact resistance than traditional plastic brackets, and can withstand the continuous impact of road gravel on the bracket. Due to the lightweight and high toughness of the composite material itself, the risk of sharp edges scratching the wiring harness after the bracket is deformed by collision is reduced, while meeting the lightweight design requirements of new energy vehicles. After the bracket is produced, workers use multiple fixing components to fix the wiring harness inside the cavity, reducing the possibility of the wiring harness shifting or shaking due to vibration during vehicle operation, and ensuring that the wiring harness is always in a stable positioning state, thus improving the operational safety and reliability of the wiring harness in new energy vehicles.

[0008] Optionally, the outer surface of the support body is provided with a plurality of first reinforcing ribs and second reinforcing ribs, the first reinforcing ribs being parallel to the length direction of the support body and the second reinforcing ribs being parallel to the width direction of the support body.

[0009] By adopting the above technical solution, the setting of the first and second reinforcing ribs simultaneously improves the overall structural strength and deformation resistance of the bracket body in both length and width dimensions, further reducing the possibility of deformation of the bracket body when the car is in motion.

[0010] Optionally, the fixing component includes a cable tie, one end of which is provided with a limiting block that engages with the first reinforcing rib, and the other end is provided with a toothed belt. The limiting block has an adjustment groove that slides with the toothed belt, and the adjustment groove is provided with a locking component. The toothed belt passes through the through hole on one side of the bracket body into the receiving cavity, winds the wire harness, and exits through the through hole on the other side, and is fixed inside the limiting block by the locking component.

[0011] By adopting the above technical solution, when fixing the wire harness, the worker first places the wire harness inside the receiving cavity, and then uses the limiting block and the first reinforcing rib to achieve the initial positioning of the cable tie. Next, the toothed band is inserted into the receiving cavity through the through hole on one side of the bracket body, wraps around the wire harness in the receiving cavity, and then exits through the through hole on the other side. The toothed band is then inserted into the adjustment groove of the limiting block, and the locking component in the adjustment groove engages with the toothed band to achieve fixation. During this process, the worker can adjust the insertion length of the toothed band in the adjustment groove according to the actual thickness of the wire harness, so that the tightness of the cable tie on the wire harness can be adapted to different specifications of wire harnesses, thereby improving the adaptability of the bracket to the wire harness.

[0012] Optionally, the locking assembly includes a gear rotatably connected in the adjusting groove, the gear meshing with the toothed end of the toothed belt, a rotating pin coaxially disposed on the gear, a locking cap threadedly connected to the outer surface of the rotating pin, and an internal thread groove that threadedly engages with the locking cap in the limiting block.

[0013] By adopting the above technical solution, when the toothed belt is pushed to mesh with the gear, the worker can operate the rotating pin to drive the gear to rotate. When the gear rotates, it pulls the toothed belt to move in the adjustment groove, thereby adjusting the tightness of the cable tie. When the adjustment is in place, the worker screws the locking cap along the thread of the rotating pin into the internal thread groove of the limit block. The threaded engagement locks the rotating pin, preventing the gear from rotating unexpectedly due to vehicle vibration. This reduces the possibility of the cable tie tightness changing due to vehicle vibration and improves the cable tie's fixing effect on the wire harness.

[0014] Optionally, the fixing component includes a cover that is detachably connected to the bracket body via a connecting component. The cover has a support ring for supporting the wire harness. Multiple covers are interconnected and are collectively fitted around the outer periphery of the wire harness.

[0015] By adopting the above technical solution, when fixing the wire harness, the worker installs the protective cover on the bracket body through the connecting component, so that the protective cover is placed on the outer periphery of the wire harness. This physically isolates the wire harness from the bracket body and other parts of the chassis, directly reducing the frictional contact between the wire harness and the outside world due to vibration, reducing the risk of scratches. The multiple internal support rings provide multi-point support for the wire harness along the length direction, preventing the wire harness from sagging or shifting locally.

[0016] Optionally, the connecting assembly includes a plug-in post that engages with the through hole. The plug-in post is disposed on the protective cover. The end of the plug-in post away from the protective cover is provided with a plurality of elastic strips along the circumference. Each elastic strip is provided with a hook block at its end. When the elastic strip is in its natural state, the elastic strip abuts against the inner wall of the through hole, and the hook block extends out of the through hole and abuts against the surface of the bracket body.

[0017] By adopting the above technical solution, when disassembling the cover, the worker first pinches several hook blocks to close the two elastic strips, then presses the hook blocks towards the cover to insert them into the through hole, and finally pulls the cover outward to disengage the support ring from the wire harness, thus completing the disassembly of the cover. When installing the cover, the worker first aligns the plug with the through hole, then pinches the two hook blocks to close the two elastic strips, inserts the hook blocks into the through hole, and pushes the cover upward. When the hook blocks extend out of the through hole, the elastic strips open outward by their own elasticity, causing the hook blocks to abut against the outer surface of the bracket body. This achieves the installation of the cover. The setting of the connecting components enables the detachable installation of the cover on the bracket body, making it convenient for workers to replace the cover according to the wire harness specifications and for replacing damaged covers.

[0018] Optionally, each of the hook blocks is provided with a guide ramp.

[0019] By adopting the above technical solution, during the process of inserting the hook block into the through hole, the worker can use the tilt angle of the guide slope to automatically guide the hook block into the through hole, reducing the possibility of installation jamming due to alignment deviation and reducing the difficulty of disassembling and assembling the protective cover.

[0020] Optionally, the outer periphery of the support body is provided with multiple nickel alloy bushings.

[0021] By adopting the above technical solution, the nickel alloy has high strength, high wear resistance and excellent fatigue resistance. It can form a local reinforcement structure at the connection between the bracket body and the automobile chassis, effectively disperse the local stress generated by the bracket body during installation or vehicle operation, reduce the possibility of cracking of the base layer and the wrapping layer due to excessive local stress, and thus further improve the structural strength of the bracket body.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. In this embodiment of the application, by setting a base layer and a wrapping layer, during the production of the bracket body, the composite material is first hot-pressed to form a base layer, and then the base layer is fixed to an injection molding machine for secondary injection molding, so that the wrapping layer is integrally wrapped around the base layer, forming a double-layer composite structure bracket body. This bracket has higher strength and impact resistance than traditional plastic brackets, and can withstand the continuous impact of road gravel on the bracket. Due to the lightweight and high toughness of the composite material itself, the risk of sharp edges scratching the wiring harness after the bracket is deformed by collision is reduced, while meeting the lightweight design requirements of new energy vehicles. 2. By setting up fixing components, after the bracket is produced, workers use multiple fixing components to fix the wiring harness inside the accommodating cavity, reducing the possibility of the wiring harness shifting or shaking due to vibration during vehicle operation, and ensuring that the wiring harness is always in a stable positioning state, thereby improving the operational safety and reliability of the wiring harness in new energy vehicles.

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses an impact-resistant high-strength bracket structure for wiring harnesses in new energy vehicles.

[0031] Example 1 Reference Figure 1 A high-strength, impact-resistant bracket structure for wiring harnesses in new energy vehicles includes a U-shaped bracket body 1. The bracket body 1 has an internal cavity 2 for placing the wiring harness 01. The bracket body 1 includes a base layer 101 and a wrapping layer 102. The base layer 101 is a fiberboard formed by hot pressing of composite materials. The wrapping layer 102 is integrally wrapped around the base layer 101 by injection molding. In this embodiment, the structural thickness of the base layer 101 is 2.2 mm, and the wall thickness of the wrapping layer 102 is 2 mm.

[0032] During the production of the bracket body 1, the composite material is first hot-pressed to form a base layer 101. Then, the base layer 101 is fixed to an injection molding machine for secondary injection molding, so that the wrapping layer 102 is integrally wrapped around the base layer 101, forming a double-layer composite structure bracket body 1. This bracket body 1 has higher strength and impact resistance than traditional plastic brackets, and can withstand the continuous impact of road gravel on the bracket. Due to the lightweight and high toughness of the composite material itself, the risk of sharp edges and corners scratching the wiring harness 01 after the bracket is deformed by collision is reduced, while meeting the lightweight design requirements of new energy vehicles.

[0033] Reference Figure 1Multiple bushings 3 made of nickel alloy are installed on the outer periphery of the bracket body 1. The bushings 3 are formed by pre-embedding zinc-nickel alloy during secondary injection molding. Each bushing 3 has a mounting hole 31 for connecting with the car chassis. Nickel alloy has high strength, high wear resistance and excellent fatigue resistance, which can form a local reinforcement structure at the connection between the bracket body 1 and the car chassis, effectively dispersing the local stress generated by the bracket body 1 during installation or vehicle operation.

[0034] Reference Figure 2 and Figure 3 The outer surface of the bracket body 1 is provided with multiple first reinforcing ribs 103 and second reinforcing ribs 104 installed in an alternating manner. The first reinforcing ribs 103 are parallel to the length direction of the bracket body 1, and the second reinforcing ribs 104 are parallel to the width direction of the bracket body 1. The arrangement of the first reinforcing ribs 103 and the second reinforcing ribs 104 simultaneously improves the overall structural strength and deformation resistance of the bracket body 1 from both length and width dimensions, further reducing the possibility of deformation of the bracket body 1 when the car is in motion.

[0035] Reference Figure 2 and Figure 3 The bracket body 1 has multiple through holes 4 along the length and width directions. The multiple through holes 4 are arranged in an array. In this embodiment, there are five groups of through holes 4 along the length direction, and two through holes 4 in each group along the width direction. The two through holes 4 distributed along the width direction of the bracket body 1 are provided with a fixing component 5 for fixing the wire harness 01. After the bracket is produced, the workers use multiple fixing components 5 to fix the wire harness 01 inside the accommodating cavity 2, reducing the possibility of the wire harness 01 being displaced and shaken due to vibration during vehicle operation, and ensuring that the wire harness 01 is always in a stable positioning state, thereby improving the operational safety and reliability of the new energy vehicle wire harness 01.

[0036] Reference Figure 2 and Figure 3 The fixing component 5 includes a cable tie 51. One end of the cable tie 51 is fixedly connected to a limiting block 52 that engages with the first reinforcing rib 103, and the other end is fixedly connected to a toothed belt 53. The toothed belt 53 is made of rubber. An adjustment groove 521 that slides with the toothed belt 53 is provided in the limiting block 52. The adjustment groove 521 is parallel to the width direction of the bracket body 1. A locking component 6 is provided in the adjustment groove 521.

[0037] Reference Figure 2 and Figure 3The locking assembly 6 includes a gear 61 rotatably connected in the adjusting groove 521. The gear 61 meshes with the toothed end of the toothed belt 53. A rotating pin 62 is coaxially fixedly connected to the gear 61. The end of the rotating pin 62 extends to the outside of the limiting block 52. A locking cap 63 is threadedly connected to the outer surface of the rotating pin 62. The locking cap 63 has an internal thread section inside and an external thread section on its outer surface. An internal thread groove 522 is opened in the limiting block 52 to thread with the locking cap 63.

[0038] When fixing the wire harness 01, the worker first places the wire harness 01 inside the receiving cavity 2. Then, the limiting block 52 and the first reinforcing rib 103 are inserted and engaged to achieve the initial positioning of the cable tie 51. Next, the toothed belt 53 is inserted into the receiving cavity 2 through the through hole 4 on one side of the bracket body 1, and after wrapping around the wire harness 01 inside the receiving cavity 2, it is pulled out through the through hole 4 on the other side. The toothed belt 53 is then inserted into the adjusting groove 521 and meshed with the gear 61. Then, the worker operates the rotating pin 62 to drive the gear 61 to rotate. When the gear 61 rotates, it pulls the toothed belt 53 to move in the adjusting groove 521. In this way, the tightness of the cable tie 51 inside the receiving cavity 2 is adaptively changed according to the actual thickness of the wire harness 01. Once the adjustment is complete, the worker screws the locking cap 63 into the inner thread groove 522 of the limiting block 52 along the thread of the rotating pin 62. At this time, the outer surface of the locking cap 63 is threadedly engaged with the inner thread groove 522, and the inner surface is threadedly engaged with the rotating pin 62. The interlocking force between the threads prevents the gear 61 from rotating unexpectedly due to vehicle vibration, thereby reducing the possibility of changes in the tightness of the cable tie 51 caused by vehicle vibration and improving the fixing effect of the cable tie 51 on the wire harness 01.

[0039] Fixing is achieved by the locking component 6 in the adjusting groove 521 engaging with the toothed belt 53. During this process, the worker can adjust the insertion length of the toothed belt 53 in the adjusting groove 521 according to the actual thickness of the wire harness 01, so that the fixing tightness of the cable tie 51 to the wire harness 01 is adapted to different specifications of wire harness 01, thereby improving the adaptability of the bracket to the wire harness 01.

[0040] Reference Figure 2 and Figure 3 The locking assembly 6 includes a gear 61 rotatably connected in the adjusting groove 521. The gear 61 meshes with the toothed end of the toothed belt 53. A rotating pin 62 is coaxially arranged on the gear 61. A locking cap 63 is threadedly connected to the outer surface of the rotating pin 62. An internal thread groove 522 is opened in the limiting block 52 to thread with the locking cap 63.

[0041] This application provides an embodiment of a high-strength, impact-resistant bracket structure for wiring harnesses in new energy vehicles. The implementation principle is as follows: During the production of the bracket body 1, the composite material is first hot-pressed to form a base layer 101. Then, the base layer 101 is fixed to an injection molding machine for secondary injection molding, causing the wrapping layer 102 to integrally wrap around the base layer 101, forming a double-layer composite bracket body 1. This bracket possesses higher strength and impact resistance than traditional plastic brackets, resisting continuous impacts from road debris. Furthermore, due to the lightweight and high toughness of the composite material, the risk of sharp edges scratching the wiring harness 01 after collision deformation is reduced, while also meeting the lightweight design requirements of new energy vehicles. After the bracket is produced, workers use multiple fixing components 5 to fix the wiring harness 01 inside the accommodating cavity 2, reducing the possibility of displacement and shaking of the wiring harness 01 due to vibration during vehicle operation, ensuring that the wiring harness 01 remains in a stable positioning state, thus improving the operational safety and reliability of the new energy vehicle wiring harness 01.

[0042] Example 2 Reference Figure 4 and Figure 5 The difference between Embodiment 2 and Embodiment 1 is that the fixing component 5 includes a cover 54 that can be detachably installed on the bracket body 1 via the connecting component 7. The covers 54 of multiple fixing components 5 are connected to each other to form the main body of the protective wire harness 01. The multiple covers 54 are together sleeved on the outer periphery of the wire harness 01. Each cover 54 has a support ring 55 fixedly connected inside for supporting the wire harness 01.

[0043] Reference Figure 4 and Figure 5 The connecting component 7 includes a plug-in post 71 that engages with the through hole 4. The plug-in post 71 is fixedly connected to the cover 54. A plurality of elastic strips 72 are evenly connected circumferentially on the end face of the plug-in post 71 away from the cover 54. In this embodiment, there are two elastic strips 72, which are respectively arranged on the radial sides of the plug-in post 71. Each end of the elastic strip 72 is integrally formed with a hook block 73. Each hook block 73 is provided with a guide slope 731 to facilitate the insertion of the plug-in post 71 into the through hole 4. When the two elastic strips 72 retract inward, the area of ​​the two hook blocks 73 spliced ​​together is smaller than the cross-sectional area of ​​the through hole 4. When the two elastic strips 72 are in their natural state, the area of ​​the two hook blocks 73 spliced ​​together is larger than the cross-sectional area of ​​the through hole 4.

[0044] The implementation principle of Example 2 is as follows: When fixing the wire harness 01, the worker places the wire harness 01 to be fixed in the receiving cavity 2, and then aligns the plug 71 on the protective cover 54 with the through hole 4. When the plug 71 is inserted into the through hole 4, the guide slope 731 contacts the edge of the through hole 4 and generates a guiding effect, pushing the two elastic strips 72 to contract inward under the pressure of the inner wall of the through hole 4. At this time, the area of ​​the two hook blocks 73 spliced ​​together is smaller than the cross-sectional area of ​​the through hole 4, and the plug 71 can be smoothly inserted into the through hole 4. After the plug 71 is fully inserted and the elastic strips 72 are freed from the constraint of the inner wall of the through hole 4 and return to their natural state, the two hook blocks 73 are spliced ​​together. Once the area is restored to be larger than the cross-sectional area of ​​the through hole 4, the hook block 73 will be locked on the side of the bracket body 1 away from the protective cover 54, thus connecting the protective cover 54 with the bracket body 1. At this time, the protective cover 54 is fitted on the outer periphery of the wire harness 01 to form a physical isolation between the wire harness 01 and the bracket body 1 and other parts of the chassis, reducing the risk of scratches. When it is necessary to repair or replace the wire harness 01, the worker first pinches the multiple hook blocks 73 to close the two elastic strips 72, then presses the hook blocks 73 toward the protective cover 54 to insert them into the through hole 4, and finally pulls the protective cover 54 outward to disengage the support ring 55 from the wire harness 01, thus completing the disassembly of the protective cover 54.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
