Specific embodiments

[0028] Next, with reference to the accompanying drawings, through the description of the embodiments, the specific embodiments of the present utility model will be further described in detail. The purpose is to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0029] As Figures 1 to 3 shown, the wire harness fixing and clamping structure for automobiles includes a fixed seat 1 and a cable tie 2. The fixed seat 1 and the cable tie 2 are of a split structure; connecting seats 11 and clamping blocks 12 are respectively provided at both ends of the fixed seat 1, an opening 14 is provided at the end of the connecting seat 11, a clamping seat 21 is provided at one end of the cable tie 2, an insertion opening 23 is provided on the clamping seat 21, a clamping boss 24 is provided at the end of the clamping seat 21, and a limiting structure is provided in the clamping boss 24 and the opening 14.

[0030] The fixed seat 1 and the cable tie 2 are designed as a split structure. In terms of production, both the fixed seat 1 and the cable tie 2 can be independently formed, so as to facilitate processing into specified dimensions. They can be designed into fir-tree-shaped interfaces of different sizes according to the openings of the vehicle body 4 to be clamped on the vehicle body 4 to meet different usage environments and reduce the development cost of re-design. The connecting seat 11 of the fixed seat 1 is used to cooperate with the clamping seat 21 of the cable tie 2, and the insertion opening 23 is used for the end of the cable tie 2 to be inserted to form a circular hoop for fixing the wire harness. Limiting structures are respectively designed on the fixed seat 1 and the cable tie 2, so that the clamping seat 21 and the cable tie 2 part can rotate relative to each other, and one cable tie 2 can meet the wire harness routing requirements in two directions.

[0031] As Figures 1 to 7 shown, the limiting structure includes a limiting protrusion 25, and the limiting protrusion 25 is provided at the end of the clamping boss 24, and a limiting step 15 is provided in the opening 14. The cable tie 2 can be fixed or rotated at an angle on the clamping boss 24 to realize different routing directions of the wire harness; through the contact between the limiting step 15 and the limiting protrusion 25, the rotation angle of the clamping boss 24 is limited to 90°, ensuring the stability of the angle and avoiding the wire harness from being twisted due to unstable clamping. During installation, the operation convenience of the operator can be improved.

[0032] As Figures 3 to 7As shown, the clamping boss 24 has a stepped structure. Since the opening 14 is adapted to the clamping boss 24 and the clamping boss 24 is designed to be stepped, it is difficult for the cable tie 2 after clamping to escape along its length direction, and the stability of the cable tie 2 for fixing the wire harness is higher.

[0033] As Figure 3 shown, the clamping boss 24 is cylindrical. The cylindrical clamping boss 24 can reduce the rotational resistance of the cable tie 2, thus facilitating the rotation to adjust the angle of the cable tie 2; the outer part of the limiting protrusion 25 has a smooth transition, which is beneficial to ensuring that when the limiting protrusion 25 contacts the limiting step 15 and avoiding interference and obstruction during the rotation process.

[0034] As Figure 2 、 Figure 5 and Figure 7 shown, the opening 14 penetrates through one side of the connecting seat 11, and the width of the opening 14 gradually decreases from the end to the middle of the connecting seat 11. In order to make the installation and disassembly process of the fixing seat 1 and the cable tie 2 more convenient and ensure the reliability of their clamping, the opening 14 penetrates through one side of the connecting seat 11, so that the clamping boss 24 can be installed and clamped or disassembled and separated laterally. Since the clamping boss 24 is stepped, the fixing seat 1 and the cable tie 2 cannot be separated from the length direction of the cable tie 2 after being clamped; designing the width of the opening 14 as above is beneficial to increasing the resistance when the clamping boss 24 enters the opening 14 and ensuring the clamping stability when the clamping boss 24 is located at the center position of the opening 14.

[0035] As Figure 3 shown, one end of the cable tie 2 is provided with a plug-in end 22, and the plug-in end 22 is inclined with respect to the cable tie 2. Setting the plug-in end 22 at an inclined angle can facilitate the formation of a regular circular ring structure after the cable tie 2 is plugged in, and the gap between the wire harness and the cable tie 2 is smaller when the wire harness is fixed, and the wire harness is fixed more stably.

[0036] As Figure 2 shown, the clamping block 12 is evenly distributed with protrusions 16, and the protrusions 16 are bevel structures. The evenly distributed protrusions 16 improve the clamping effect of the fixing seat 1 on the vehicle body 4. The protrusions 16 are bevel structures, so that the resistance is greater when the fixing seat 1 moves in the direction of separating from the fixing point of the vehicle body 4, thereby further improving the anti-escape effect.

[0037] As Figure 2 、 Figure 4 and Figure 6 shown, a baffle 13 is provided between the connecting seat 11 and the clamping block 12. When the baffle 13 abuts against the fixing point of the vehicle body 4, the clamping block 12 protrudes a certain length from the fixing point of the vehicle body 4, further reducing the probability of the fixing seat 1 detaching from the fixing point of the vehicle body 4, and the operator can also identify and judge that the clamping block 12 is clamped in place.

[0038] As Figure 4 and Figure 6As shown, the connecting seat 11 and the clamping block 12 are arranged in an L shape. The above structure can facilitate the clamping connection of the clamping block 12 to the fixing point of the vehicle body 4 from the side, which is beneficial to reducing the size of the wire harness fixing part.

[0039] As Figure 7 shown, the limiting protrusion 25 contacts the limiting step 15. The above structure is the case where the cable tie 2 rotates 90° to the limit.

[0040] Referring to the appendix Figure 8 , when the fixing point on the vehicle body 4 is adjusted and the bracket 5 is removed, use the cable tie 2 to fix the wire harness 3, and clamp the clamping block 12 on the bracket 5, then the fixing of the wire harness can be satisfied. At this time, the axis of the wire harness 3 and the axis of the mounting hole of the vehicle body 4 are not coplanar or perpendicular to each other; referring to the appendix Figure 9 , when the fixing point on the vehicle body 4 is equipped with the bracket 5, the wire harness and the cable tie 2 do not need to be replaced. Only need to rotate the cable tie 2 around the clamping boss 24 by 90° to the limit. At this time, the axis of the wire harness 3 and the axis of the mounting hole of the vehicle body 4 are coplanar. By changing the fixing point of the fixing seat 1 on the vehicle body 4, there is no need to adjust the wire harness routing direction and replace the wire harness fixing part. The above two cases face different installation environments. By changing the angle of the cable tie 2 on the fixing seat 1, while ensuring that the routing direction of the wire harness 3 remains unchanged, the unity of the structure is ensured, that is, higher versatility is achieved and the development cost is reduced. Correspondingly, in other wire harness layout occasions, the wire harness 3 can also be adjusted to the required routing direction by only changing the position of the fixing seat 1 or adjusting the angle of the cable tie 2.

[0041] For this wire harness fixing and clamping structure, compared with the integral structure of the traditional wire harness fixing part, the wire harness fixing part is designed as a split structure. A limiting structure and a clamping structure are jointly set at the connecting part of the fixing seat 1 and the cable tie 2, so that the two can rotate relative to each other by 90 degrees, so as to adapt to the wire harness routing in different directions and meet the wire harness routing and fixing requirements at different installation positions of the vehicle body 4. And the clamping effect is reliable, the difficulty of wire harness assembly is reduced, the assembly efficiency is improved, at the same time, the types of wire harness fixing parts are reduced, it has higher versatility, the unity of the wire harness fixing parts is improved, and it is beneficial to reduce the development cost.

[0042] The above has made an exemplary description of the present invention in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above methods. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present invention; or without improvement, the above concept and technical solution of the present invention are directly applied to other occasions, all are within the protection scope of the present invention.
