Description

Technical Field

[0001] This utility model relates to the field of motor vehicle wiring harness arrangement technology, and more specifically, to a motor vehicle wiring harness positioning bracket. Background Technology

[0002] In the automotive manufacturing industry, wiring harnesses, as a core component of the vehicle's electrical system, play a crucial role in power transmission and signal delivery. With the increasing electrification and intelligence of automobiles, the number of in-vehicle electronic devices has significantly increased, leading to a corresponding increase in the complexity and length of wiring harnesses. However, the arrangement and fixation of wiring harnesses directly affect the safety, reliability, and assembly efficiency of the entire vehicle. Improper wiring harness fixation can lead to problems such as wear, short circuits, and signal interference, and may even cause vehicle malfunctions or safety hazards. Therefore, the design and optimization of wiring harness positioning brackets has become one of the key technologies in automotive manufacturing.

[0003] Currently, traditional wiring harness fixing methods mainly rely on cable ties, tape, or simple plastic clips. Although these methods are low in cost, in long-term use, cable tie fixing may cause excessive local stress on the wiring harness, making it prone to loosening or breakage when the vehicle vibrates or the temperature changes. Tape fixing is prone to losing its adhesiveness due to high temperature or aging, thus losing its function of positioning and fixing the wiring harness.

[0004] Therefore, in view of this, the existing structure is studied and improved to provide a motor vehicle wiring harness positioning bracket, in order to achieve a more practical purpose. Utility Model Content

[0005] 1. Technical problems to be solved To address the problems existing in the prior art, the purpose of this utility model is to provide a motor vehicle wiring harness positioning bracket. It can fix the wiring harness through the wiring harness positioning component, ensuring the stability of the wiring harness positioning and fixing, avoiding the problems of cable ties aging and breaking or tape aging and losing its adhesiveness. At the same time, the device achieves protection for the wiring harness, and the wiring harness positioning component can be adapted to fixing various specifications of wiring harnesses, improving the practicality of the device.

[0006] 2. Technical Solution To solve the above problems, the present invention adopts the following technical solution.

[0007] A motor vehicle wiring harness positioning bracket includes a metal plate, which is fixed to the vehicle body by bolts. Several inner cylinders are fixedly installed from one side to the other on the metal plate. A hexagonal rotating cylinder is movably connected inside the inner cylinder. Wiring harness positioning components are fixedly provided on all six sides of the hexagonal rotating cylinder. The wire harness positioning assembly includes a protective frame. A cylindrical track is fixedly installed at both the top and bottom of the inner side of the protective frame. Two clamping pieces are slidably connected on the cylindrical track. The clamping pieces are arranged symmetrically on an axis. A strong spring is provided between the outer side of the clamping piece and the inner wall of the protective frame. The strong spring is sleeved on the side of the cylindrical track at the corresponding position and is always kept in a compressed state. An arc-shaped opening is fixedly provided on one side of the clamping piece.

[0008] Furthermore, the inner side of the inner cylinder is provided with a first tube groove and a second tube groove, and the first tube groove and the second tube groove are interconnected. Multiple slots are provided at the junction of the second tube groove and the first tube groove, and the first tube groove, the second tube groove and the slots are interconnected. The hexagonal drum has six spokes fixedly installed on its inner side, and a movable rod is fixedly installed at the center of each spoke. A chuck is fixedly installed at one end of the movable rod.

[0009] Furthermore, the six spokes are evenly distributed at the same angle, and the center of each of the six spokes is integrally cast.

[0010] Furthermore, the movable rod slides inside the first tube groove, and before the chuck moves, the chuck teeth engage with the corresponding slots.

[0011] Furthermore, after the chuck moves, it is pushed into the second groove and remains free to rotate.

[0012] Furthermore, a contact ball is fixedly installed on the side of the chuck, and a cross-shaped workpiece is slidably connected in the second tube groove. One side of the cross-shaped workpiece contacts the contact ball, and several return springs are fixedly installed between the other side of the cross-shaped workpiece and the inner end of the second tube groove.

[0013] Furthermore, the central axis of the hexagonal rotary drum is the center of symmetry, and the six wire harness positioning components are centrally symmetrically distributed.

[0014] 3. Beneficial Effects Compared with existing technologies, the advantages of this utility model are: This solution uses a wire harness positioning assembly to fix the wire harness. The wire harness positioning assembly is a mechanical device. When fixing the wire harness, a strong spring is used in conjunction with a clamp to clamp the wire harness, ensuring the stability of the wire harness positioning and fixing. At the same time, it avoids the problems of cable ties aging and breaking or tape aging and losing its stickiness. Furthermore, when the wire harness is positioned and fixed, the angle of the wire harness can be changed by rotating the hexagonal drum, which reduces the excessive bending angle during wire harness wiring and achieves protection of the wire harness. In addition, the wire harness positioning component can be adapted to the fixing of various wire harnesses of different specifications, which improves the practicality of the device.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] Example: Please see Figure 1 - Figure 8A motor vehicle wiring harness positioning bracket includes a metal plate 1, which is fixed to the vehicle body by bolts. Several inner cylinders 2 are fixedly installed from one side to the other on the metal plate 1. A hexagonal rotating cylinder 3 is movably connected inside the inner cylinder 2. Wiring harness positioning components 4 are fixedly installed on all six sides of the hexagonal rotating cylinder 3. The wire harness positioning assembly 4 includes a protective frame 401. A cylindrical track 402 is fixedly installed at the top and bottom of the inner side of the protective frame 401. Two clamping pieces 403 are slidably connected on the cylindrical track 402. The clamping pieces 403 are arranged symmetrically on an axis. A strong spring 404 is provided between the outer side of the clamping piece 403 and the inner wall of the protective frame 401. The strong spring 404 is sleeved on the side of the cylindrical track 402 at the corresponding position. The strong spring 404 is always kept in a compressed state. An arc-shaped opening 405 is fixedly provided on one side of the clamping piece 403.

[0019] The arc-shaped opening 405 can be easily opened when pressure is applied, allowing the wire harness to be pushed between the two clips 403 from the arc-shaped opening 405. Then, the elasticity of the strong spring 404 causes the two clips 403 to slide along the cylindrical track 402 and move closer together, thereby limiting the wire harness between the two clips 403, completing the positioning and fixing. During this process, the protective frame 401 will play a certain protective role for its internal structure.

[0020] See Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 Specifically, the inner side of the inner cylinder 2 is provided with a first pipe groove 201 and a second pipe groove 202, and the first pipe groove 201 and the second pipe groove 202 are interconnected. Multiple slots 203 are provided at the junction of the second pipe groove 202 and the first pipe groove 201, and the first pipe groove 201, the second pipe groove 202 and the slots 203 are interconnected. Six spokes 301 are fixedly installed on the inner side of the hexagonal rotary cylinder 3, and a movable rod 302 is fixedly installed at the center of the spokes 301. A chuck 303 is fixedly installed at one end of the movable rod 302.

[0021] Specifically, the six spokes 301 are evenly distributed at equal angles, and the center of each of the six spokes 301 is integrally cast.

[0022] There is a gap between any two spokes 301. When the hexagonal drum 3 rotates, it is easy to put your finger between the two spokes 301, which makes it easier to push the hexagonal drum 3 to rotate.

[0023] Specifically, the movable rod 302 slides inside the first tube groove 201, and before the chuck 303 moves, the teeth of the chuck 303 engage with the corresponding groove 203.

[0024] The slot 203 is used to limit the tooth, thereby limiting the chuck 303. At this time, the movable rod 302 and the hexagonal drum 3 cannot rotate, thus limiting the angle of the hexagonal drum 3.

[0025] The number of teeth on the chuck 303 is the same as the number of slots 203, both being eighteen. This allows the hexagonal rotary drum 3 to form a limit lock at various different angles.

[0026] Specifically, after the chuck 303 moves, it is pushed into the second tube groove 202 and remains free to rotate.

[0027] When the hexagonal rotary drum 3 is pressed down, the movable rod 302 slides inside the first tube groove 201 until the chuck 303 is fully pushed into the second tube groove 202. At this time, the hexagonal rotary drum 3 can rotate freely, thereby adjusting the angle of the hexagonal rotary drum 3 so that the wire harness that needs to be positioned is inserted into the appropriate wire harness positioning component 4.

[0028] Specifically, a contact ball 3031 is fixedly installed on the side of the chuck 303, and a cross-shaped workpiece 2021 is slidably connected in the second tube groove 202. One side of the cross-shaped workpiece 2021 contacts the contact ball 3031, and several return springs 2022 are fixedly installed between the other side of the cross-shaped workpiece 2021 and the inner end of the second tube groove 202.

[0029] The contact area between the contact ball 3031 and the cross-shaped workpiece 2021 is small. When the chuck 303 is fully pushed into the second tube groove 202, the friction between the contact ball 3031 and the cross-shaped workpiece 2021 is small when the hexagonal drum 3 rotates. This can effectively reduce the inconvenience of the hexagonal drum 3 when it rotates.

[0030] The return spring 2022 is always in a compressed state inside the second tube groove 202. If no additional pressure is applied to the hexagonal drum 3, the chuck 303 will be locked into the groove 203 under the action of the return spring 2022, thus locking the chuck 303 and the hexagonal drum 3.

[0031] See Figure 1 , Figure 2 , Figure 3 , Figure 4 Specifically, the central axis of the hexagonal rotary drum 3 is the center of symmetry, and the six wire harness positioning components 4 are distributed in a centrally symmetrical manner.

[0032] The six wiring harness positioning components 4 can open and close to different sizes according to the thickness of the wiring harness, thus enabling the fixing of wiring harnesses of different thicknesses on motor vehicles.

[0033] Working principle: When using the device, firstly, adjust the position of the hexagonal rotary drum 3 according to the tilt angle of the wire harness so that the wire harness matches the position of the corresponding wire harness positioning component 4, specifically: Press down on the hexagonal drum 3 to push the chuck 303 fully into the second tube groove 202. At this time, the return spring 2022 is further compressed. Then, rotate the hexagonal drum 3 to match the position of the wire harness with the corresponding wire harness positioning component 4. Release the hexagonal drum 3, and under the action of the return spring 2022, the chuck 303 will re-enter the slot 203 (if the chuck 303 is not in the slot 203, manually rotate the hexagonal drum 3 at a small angle). Then, the wire harness is positioned and fixed. The wire harness is inserted through the arc-shaped opening 405. At this time, the two clamps 403 open, and the strong spring 404 is further compressed until the wire harness is inserted between the two clamps 403. Then, the elasticity of the strong spring 404 is used to make the two clamps 403 slide along the cylindrical track 402 and move closer together, thereby limiting the wire harness between the two clamps 403, completing the positioning and fixing.

[0034] This allows the device to be used to position and fix the vehicle wiring harness.

[0035] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
