[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] In the claims, specification and the above-mentioned drawings of the utility model, unless otherwise clearly defined, the use of terms such as "first", "second" or "third" etc. is to distinguish different objects rather than to describe a specific order.

[0029] Please also read Figures 1 to 9, the wire harness fixing device provided by the utility model is now described. The wiring harness fixing device comprises: a first tube shell 1 and a second tube shell 2, the first tube shell 1 has a first main guide portion 11 and a first branch guide portion 14 connected to the first main guide portion 11, the branch wiring harness direction 7 constrained by the first branch guide portion 14 is perpendicular to the main wiring harness direction 6 constrained by the first main guide portion 11; the first main guide portion 11 has a supporting plane 13 that can be supported on the vehicle body, and the plane formed by the main wiring harness direction 6 and the branch wiring harness direction 7 is parallel to the supporting plane 13; the first main guide portion 11 has a fixing structure that can be fixed to the fixing member 4; the second tube shell 2 has a second main guide portion 21 and a second branch guide portion 22 connected to the second main guide portion 21; the second main guide portion 21 and the first main guide portion 11 are clamped together by the first clamping structure 5 to form a main wiring harness limiting hole; the second branch guide portion 22 and the first branch guide portion 14 are clamped together by the second clamping structure 3 to form a branch wiring harness limiting hole; wherein, the first clamping structure 5 and the second clamping structure 3 are respectively arranged on both sides of the main wiring harness direction 6.

[0030] The wire harness fixing device provided by the utility model has the following beneficial effects: (1) the wire harness is fixed by using a tube shell. During installation, the first tube shell 1 is first fixed to the fixing member 4, the wire harness is arranged along the first tube shell 1, and then the second tube shell 2 is clamped on the first tube shell 1 to fix the wire harness. The installation is simple and convenient, and the wire harness is not easily damaged due to the protection of the tube shell to the wire harness; (2) during disassembly, only the second tube shell 2 needs to be removed from the first tube shell 1 to expose the wire harness. The disassembly is convenient, and the wire harness will not be touched due to the protection of the tube shell, which also avoids the problem of the wire harness being scratched and damaged; (3) two tube shells are clamped to each other The main wiring harness limiting hole is formed to fix the main wiring harness, thereby providing reliable protection for the main wiring harness, and the branch wiring harness is fixed through the branch wiring harness limiting hole to protect the branch wiring harness, thereby avoiding the problem of short circuit caused by wear and friction damage to the outer skin of the wiring harness, thereby improving the durability of the wiring harness and reducing safety hazards; (4) The plane formed by the center line of the main wiring harness limiting hole and the center line of the branch wiring harness limiting hole is parallel to the support plane 13 for fixing the wiring harness, thereby meeting the adaptability requirements for fixing wiring harnesses with different functions and improving the adaptability of the entire device; at the same time, the support plane 13 can be supported on the vehicle body, and the fixing part 4 is integrally constructed or detachably installed on the vehicle body, thereby improving the firmness and reliability of the wiring harness after fixing.

[0031] It should also be noted that since the existing devices that use tube shells to fix the wiring harness mostly only have one main wiring harness limiting hole, they cannot adapt to the complex situation of the current line layout. The present application improves the flexibility and adaptability of the wiring harness layout by setting a branch wiring harness limiting hole parallel to the support plane 13 on the first tube shell 1, which can reduce the number of wiring harness fixing devices used. In addition, this tube shell type wiring harness fixing device can also provide good protection for the branching parts of the main wiring harness and the branch wiring harness, thereby improving the safety performance of the control system.

[0032] The present application is fixed with the first tube shell 1 and the fixing member 4. When the wiring harness needs to be fixed, the first tube shell 1 is first fixed to the fixing member 4, the main wiring harness is arranged along the first main guide portion 11, the branch wiring harness is arranged along the first branch guide portion 14, and then the second main guide portion 21 is clamped on the first main guide portion 11, and the second branch guide portion 22 is clamped on the first branch guide portion 14, so that the branch wire fixation of the wiring harness can be achieved.

[0033] Among them, the main wiring harness limiting hole and the branch wiring harness limiting hole formed by the two tube shells being clamped together are both round holes adapted to the wiring harness; therefore, each main guide part and each branch guide part are provided with a semicircular hole.

[0034] Two second clamping structures 3 are arranged corresponding to the branch wire harness limiting hole of the present application, so that a three-point clamping is formed between the two tube shells, and the connection line of the three-point clamping positions forms an isosceles triangle. The clamping points are evenly arranged, ensuring the stability of the wire harness after the two tube shells are clamped. Among them, the two second clamping structures 3 are symmetrically distributed with the straight line passing through the first clamping structure 5 and perpendicular to the main limiting hole of the wire harness as the symmetry axis.

[0035] In some embodiments, see Figures 4 to 9 As shown, the first clamping structure 5 includes a main clamping structure, which includes a first clamping interface 54 provided on the first main guide portion 11 and a first clamping claw 51 provided on the second main guide portion 21, and the first clamping claw 51 is clamped on the first clamping interface 54. Optionally, the first clamping interface 54 can also be arranged on the second main guide portion 21, and in this case, the first clamping claw 51 is arranged on the first main guide portion 11. The clamping method is simple and convenient to connect. After clamping, the clamping claw extends into the clamping interface, and the end faces of the two tube shells fit together to form a closed main harness limiting hole and a branch harness limiting hole, thereby avoiding the risk of the harness being scratched and damaged.

[0036] In some embodiments, see Figure 7 and Fig. 9, a main clamping groove 55 is provided on the inner wall of the first clamping interface 54, and a first clamping protrusion 56 is provided on the first clamping claw 51 to be clamped with the main clamping groove 55. The clamping structure, the first clamping claw 51 is integrally formed on the first main guide portion 11, and the free end of the first clamping claw 51 is in a suspended state, so it has a certain resilience. When clamping, the first clamping claw 51 moves into the first clamping interface 54, the first clamping protrusion 56 contacts the inner wall of the first clamping interface 54 and pushes the first clamping claw 51 away from the inner wall, so that the first clamping claw 51 is deformed and obtains elastic force. When the first clamping protrusion 56 moves to the position of the main clamping groove 55, due to the avoidance of the main clamping groove 55, the first clamping claw 51 is reset to the initial suspension state under the action of the elastic force, so that the first clamping protrusion 56 abuts against the side wall of the main clamping groove 55, and the clamping connection is realized.

[0037] In some embodiments, see Figure 7 and Fig. 9 The first clamping structure 5 also includes an auxiliary clamping structure, which includes an auxiliary clamping groove 53 provided on the first main guide portion 11 and a clamping rib 58 provided on the first clamping claw 51, and the clamping rib 58 is inserted into the auxiliary clamping groove 53. When the first clamping claw 51 moves toward the first clamping interface 54, the clamping rib 58 also moves toward the auxiliary clamping groove 53 synchronously. The clamping of the first clamping structure 5 can realize the limitation of the second tube shell 2 along the vertical direction perpendicular to the main wiring harness direction 6, and the direction along the main wiring harness direction 6 can be limited by the auxiliary clamping structure, so as to realize the reliable connection between the second tube shell 2 and the first tube shell 1.

[0038] Optionally, two auxiliary clamping grooves 53 are provided on the first main guide portion 11, and correspondingly, two clamping ribs 58 are provided on the first clamping claw 51. At this time, an avoidance opening 52 is required to be provided on the second main guide portion 21 to avoid the isolation block formed between the two auxiliary clamping grooves 53, so that the clamping rib 58 can be inserted into the auxiliary clamping groove 53.

[0039] In some embodiments, see Figures 1 to 8 The first main guide portion 11 is provided with an outer convex fixing portion 12, and the first card interface 54 and the fixing structure are both provided on the outer convex fixing portion 12; wherein the fixing structure includes the first card interface 54 and a second card protrusion 57 provided on the inner wall of the first card interface 54, and the second card protrusion 57 and the main card connection groove 55 are respectively provided on two inner walls opposite to the first card interface 54. The fixing structure of the present application shares the first card interface 54 with the first card connection structure 5, reducing the number of card interfaces provided, thereby reducing the volume of the first tube shell 1. The fixing member 4 is provided with a card connection hole 41 that is engaged with the second card protrusion 57.

[0040] The side of the convex fixing portion 12 facing away from the second tube shell 2 also constitutes a part of the supporting plane 13, thereby expanding the surface area of ​​the supporting plane 13, thereby ensuring the position stability of the device after being fixed.

[0041] The first tube shell 1 is fixed to the fixing member 4 by a clamping method or by a detachable bolting method, wherein the fixing member 4 can be integrated with the vehicle body or fixed to the vehicle body by clamping or screwing, and the supporting plane 13 can be supported at a certain position of the vehicle body.

[0042] In some embodiments, see Figures 1 to 9 The second main guide portion 21 is provided with an overlap portion 211 that can overlap the convex fixing portion 12, and the first clamping claw 51 is provided on the overlap portion 211. Since the first main guide portion 11 needs to be fixed on the fixing member 4, the convex fixing portion 12 is constructed. At this time, the second main guide portion 21 is provided with an extended overlap portion 211, and a large area of ​​contact is formed between the overlap portion 211 and the convex fixing portion 12, thereby improving the firmness of the fixing of the second tube shell 2.

[0043] In some embodiments, see Figures 5 to 9 , a first arc rib 111 is also provided on the first main guide portion 11, and a second arc rib 212 is provided on the second main guide portion 21. The first arc rib 111 and the second arc rib 212 support and constrain the main wire harness in the main wire harness limiting hole. Specifically, the first arc rib 111 and the second arc rib 212 are connected to form a complete circular ring, and the main wire harness is supported on this circular ring, which reduces the contact area between the main wire harness and the surface of the entity (such as the first main guide portion 11) and facilitates heat dissipation. Among them, the first arc rib 111 on the first main guide portion 11 is arranged at both ends of the main wire harness direction 6, forming two-point support for the main wire harness, ensuring the coaxiality of the main wire harness and the main wire harness limiting hole, and avoiding the main wire harness from contacting the inner wall of the main wire harness limiting hole. In this way, in the main wiring harness limiting hole, the main wiring harness only forms line contact with the arc rib, and a through heat dissipation space is formed between the main wiring harness and the hole wall of the main wiring harness limiting hole, so that the heat of the wiring harness can be transferred to the outside of the tube shell in time. The tube shell serves as a protection for the wiring harness. Through the arc ribs at both ends, the direction of the wiring harness can be controlled and fixed, ensuring the heat dissipation effect of the main wiring harness and avoiding circuit failures caused by overheating of the main wiring harness.

[0044] Similarly, a third arc rib 142 is disposed in the first branch guide portion 14, and a fourth arc rib 221 enclosed by the third arc rib 142 is disposed in the second branch guide portion 22, so as to support the branch wire harness and facilitate heat dissipation of the branch wire harness.

[0045] In some embodiments, see Figures 1 to 9The second clamping structure 3 includes a second clamping claw 31 disposed on the first branch guide portion 14 and a second clamping interface 32 disposed on the second branch guide portion 22, and the second clamping claw 31 is clamped on the second clamping interface 32. Optionally, the second clamping claw 31 is disposed on the second branch guide portion 22, and the second clamping interface 32 is disposed on the first branch guide portion 14.

[0046] In some embodiments, see Figures 1 to 8 The end of the first branch guide portion 14 is provided with a limiting portion 141 that can abut against the end of the second branch guide portion 22. The limiting portion 141 is a protrusion integrally formed on the first tube shell 1 and protruding toward the second tube shell 2, which forms a response with the first clamping structure 5 on the opposite side to limit the second tube shell 2.

[0047] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0048] Based on the same inventive concept, an embodiment of the present application also provides a vehicle, including the wiring harness fixing device.

[0049] The vehicle provided by the utility model adopts the wire harness fixing device, which is simple and convenient to install and disassemble, and can improve the durability of the fixed wire harness, thereby improving the safety of the entire vehicle.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
