Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness bracket technology, specifically a guide bracket for automotive wiring harnesses. Background Technology

[0002] In automobile manufacturing, wiring harnesses, as a crucial component of the automotive electrical system, bear the critical responsibility of transmitting electrical energy and signals. The limited space inside a car, coupled with the numerous and complex wiring harnesses, means that without effective guidance and securing, they can easily become tangled and interfere with each other. This not only affects the aesthetics and tidiness of the car's interior but, more importantly, can lead to wiring harness wear, short circuits, and other malfunctions, thereby affecting the normal operation of the automotive electrical system and even posing safety hazards.

[0003] Most existing automotive wiring harness guide brackets have simple structures and limited functions. Some guide brackets can only achieve basic wiring harness fixation and cannot be flexibly adjusted according to the actual routing and bending requirements of the wiring harness, making them inconvenient to use. For example, a bracket for an automotive wiring harness disclosed in Chinese patent application number CN201510996196.9 includes a body and a movable body. The body includes a closed part, a first open part and a second open part. The closed part is a U-shaped closed part. The first open part and the second open part are both inverted trapezoidal plates with open tops. The movable body is a coiled elastic plate and includes a straight plate, a contact plate, a support plate and a guide plate. The movable body can be embedded in the closed part for fixation.

[0004] Therefore, we need to propose a guide bracket for automotive wiring harnesses. Utility Model Content

[0005] The purpose of this utility model is to provide a guide bracket for automotive wiring harnesses, which can flexibly change the guide direction of the wiring harness according to the actual routing and bending requirements of the wiring harness inside the vehicle. This overcomes the shortcomings of existing guide brackets that cannot flexibly adjust the guide direction, greatly facilitating the arrangement and installation of the wiring harness, and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A guide bracket for automotive wiring harnesses, comprising:

[0008] The base is designed in the shape of a "Z" and has fixing holes at both ends for fixing the base.

[0009] The support block is rotatably mounted on the top of the base. Elastic clips are symmetrically arranged on both sides of the top of the support block. The elastic clips are designed in an arc shape. The elastic clips are used to fix and position the wire harness by bolts. The guide direction can be adjusted by rotating the support block.

[0010] Preferably, the two sets of elastic clips and support blocks form a circle with a notch at the top for inserting the wire harness. The top of the two sets of elastic clips is provided with end pieces, and each set of end pieces has a hole for bolts to pass through.

[0011] Preferably, a connecting post is provided at the bottom center of the support block, and a through hole is provided at the top center of the base. The connecting post is slidably inserted into the through hole, and the connecting post can rotate within the through hole.

[0012] Preferably, the lower end of the connecting column is connected to a limiting block through a through hole, and a compression spring is sleeved on the connecting rod between the bottom of the base and the limiting block. The compression spring causes the support block to fit against the top surface of the base.

[0013] Preferably, the bottom of the support block is provided with several sets of positioning teeth at equal intervals around the connecting column. The positioning teeth are triangular in design. The top surface of the base is provided with several sets of positioning grooves at equal intervals around the through hole. The positioning grooves and positioning teeth correspond one to one and are compatible. When the support block is attached to the top surface of the base, the positioning teeth are inserted into the positioning grooves to prevent the wire harness from shifting.

[0014] Preferably, a rubber pad is bonded to the inner wall of the elastic clip, and the inner wall of the rubber pad is provided with anti-slip texture.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The support block of this utility model is rotatably mounted on the top of the base. By rotating the support block, the guiding direction can be adjusted. It can flexibly change the guiding direction of the wiring harness according to the actual route and bending requirements of the wiring harness in the car, overcoming the shortcomings of the existing guide brackets that cannot flexibly adjust the guiding direction, and greatly facilitating the arrangement and installation of the wiring harness.

[0017] 2. The positioning teeth set around the bottom of the support block and the positioning grooves opened around the top of the base correspond one-to-one and are compatible. When the spring is compressed and the support block is pressed against the top surface of the base, the positioning teeth are inserted into the positioning grooves, which effectively prevents the wiring harness from shifting due to vibration and other factors during vehicle operation and enhances the stability of the wiring harness fixation.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0024] Please refer to Figure 1-4 , the present utility model provides a technical solution:

[0025] A guiding bracket for an automotive wire harness, comprising:

[0026] A base 1, the base 1 is designed in a U-shape, and fixing holes 2 are provided at both ends of the base 1 for fixing the base 1; two groups of elastic clips 3 and support blocks 13 form a circular shape with a notch at the top for the wire harness to be placed in, end pieces 4 are provided at the tops of the two groups of elastic clips 3, and holes for bolts 5 to pass through are provided on both of the two groups of end pieces 4.

[0027] A support block 13, rotatably arranged on the top of the base 1, elastic clips 3 are symmetrically arranged on both sides of the top of the support block 13, the elastic clips 3 are designed in an arc shape, the elastic clips 3 fix and position the wire harness through bolts 5, and the guiding direction can be adjusted by rotating the support block 13. A connecting column 8 is provided at the center of the bottom of the support block 13, a through hole 6 is provided at the center of the top of the base 1, and the connecting column 8 is slidably inserted into the through hole 6, and the connecting column 8 can rotate in the through hole 6.

[0028] The U-shaped base 1 is connected to the vehicle body through the fixing holes 2 (hole diameter 8 - 10 mm) at both ends, and the support block 13 is inserted into the through hole 6 of the base 1 through the connecting column 8 at the bottom to form a guiding structure that can rotate 360°. The arc-shaped elastic clips 3 on the top of the support block 13 and the support block 13 enclose a circular space (diameter φ8 - φ25 mm). After the wire harness is placed through the top notch, the clip is locked by the bolt 5 on the end piece 4, and the wire harness is clamped by the elastic force of the clip.

[0029] Replacing the traditional fixed bracket, the guiding direction can be flexibly adjusted (adapting to any direction of the wire harness) by rotating the support block 13, and the elastic clip 3 and the bolt 5 can adapt to wire harnesses of different diameters, solving the problems of fixed direction and poor adaptability of the traditional bracket.

[0030] For a preferred embodiment, please refer to Figure 1-4 :

[0031] The lower end of the connecting column 8 is connected to the limiting block 10 through the through hole 6. A compression spring 11 is sleeved on the connecting rod between the bottom of the base 1 and the limiting block 10. The compression spring 11 makes the support block 13 fit against the top surface of the base 1. Several sets of positioning teeth 9 are equidistantly arranged around the bottom of the support block 13 around the connecting column 8. The positioning teeth 9 are triangular in design. Several sets of positioning grooves 7 are equidistantly arranged around the through hole 6 on the top surface of the base 1. The positioning grooves 7 and the positioning teeth 9 correspond one-to-one and fit together. When the support block 13 fits against the top surface of the base 1, the positioning teeth 9 are inserted into the interior of the positioning grooves 7 to prevent the wire harness from shifting.

[0032] The connecting column 8 can rotate and slide axially simultaneously within the through hole 6 of the base 1. When the support block 13 is lifted, the compression spring 11 is compressed, and the positioning teeth 9 at the bottom of the support block 13 disengage from the positioning groove 7 of the base 1. At this time, the support block 13 can be freely rotated to adjust the angle. After being released, the spring returns to its original position, and the positioning teeth 9 re-embed into the corresponding positioning groove 7 (e.g., the spacing between the positioning teeth 9 is 15°-30°). The compression spring 11 applies a downward pressure to the limiting block 10, so that the positioning teeth 9 will not easily disengage from the positioning groove 7, thus achieving angle locking.

[0033] The guide angle can be adjusted without tools. The meshing structure of the positioning teeth 9 and the positioning groove 7 ensures that there is no loosening after the angle is fixed, thus solving the problem of directional deviation of the wire harness caused by vibration.

[0034] For a preferred embodiment, please refer to Figure 1-4 :

[0035] A rubber pad 12 is bonded to the inner wall of the elastic clip 3, and the inner wall of the rubber pad 12 is distributed with anti-slip texture.

[0036] The rubber pad 12 (thickness 1-2mm) on the inner wall of the elastic clip 3 deforms when clamped, and fits tightly against the surface of the wire harness. Combined with the anti-slip texture on the inner wall (texture depth 0.3-0.5mm), it increases the coefficient of friction and has a dual effect to prevent the wire harness from slipping.

[0037] This design avoids insulation wear caused by hard contact between the clamp and the wiring harness, while also enhancing clamping stability, allowing the amount of wiring harness slippage to be controlled even under severe vehicle vibration.

[0038] The contact surfaces of the support block 13 and the base 1 are both bonded with rubber layers to buffer vibrations and increase the friction between the support block 13 and the base 1 to prevent relative rotation after positioning.

[0039] The rubber layer (1-1.5mm thick) on the contact surface between the support block 13 and the base 1 can absorb vibration energy and increase the static friction between them; together with the mechanical locking of the positioning teeth 9, a double anti-loosening guarantee is formed.

[0040] To reduce the impact of vehicle vibration on the wiring harness and prevent the support block 13 from rotating unexpectedly due to vibration after positioning is completed.

[0041] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
