Description

Technical Field

[0001] The utility model belongs to the technical field of vehicles, and in particular relates to a wire harness fixing device and a vehicle. Background Art

[0002] As cars become more intelligent and functional, there are more and more electrical components on the car, and with them more and more matching wires, the wiring harness becomes thicker and heavier. A main wiring harness for a whole vehicle has multiple branch wiring harnesses, just like a tree trunk and branches, branching in different directions to connect the target devices. The main wiring harness for a whole vehicle often takes the dashboard as the core part and extends forward and backward. Due to length or ease of assembly, the wiring harnesses of some cars are divided into front wiring harnesses (including instruments, engines, headlight assemblies, air conditioners, batteries), rear wiring harnesses (taillight assemblies, license plate lights, trunk lights), roof wiring harnesses (doors, ceiling lights, audio speakers), etc. Therefore, the wiring harnesses on the car form the network body of the car circuit. How to make a large number of wiring harnesses more effectively and reasonably arranged in the limited space of the car to ensure the safe and effective driving of the vehicle.

[0003] At present, most vehicles simply use cable ties and wire clips to fix the wiring harness. There are many problems with this method of fixing the wiring harness, as follows: (1) The cable tie fixing method of the wire clip can easily damage the wire clip and the cable tie during installation, and may also cause scratches on the outer insulation layer of the wiring harness, making installation inconvenient; (2) It is inconvenient to disassemble. It is difficult to disassemble after fixing, and the cable ties, wire clips and other fixing methods will cause certain damage to the outer insulation layer of the wiring harness. Long-term use will cause damage to the wiring harness, resulting in poor contact or short circuit, etc., and is not conducive to subsequent disassembly and maintenance; (3) It is difficult to achieve stable fixation of the main wiring harness, especially at the branching point of the main wiring harness. It is impossible to effectively achieve reliable fixation of the main wiring harness and the branch wiring harness. When the vehicle is bumpy and shaken during driving, the wiring harness will also shake, causing interference and mutual friction between the wiring harnesses, which seriously affects the durability of the outer layer of the wiring harness and poses certain safety hazards.

[0028] 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.

[0029] In the present application, terms such as “first” and “second” are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship of quantity, priority or sequence between these entities or operations.

[0030] Please also read Figures 1 to 9, the wiring harness fixing device provided by the utility model is now described. The wiring harness fixing device includes 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 fixing structure that can be fixed to a fixing member 4; the first main guide portion 11 has a supporting plane 13 that can be supported on the vehicle body; the second tube shell 2 has a second main guide portion 21 and a branch guide portion 22; the second main guide portion 21 and the first main guide portion 11 are clamped together by a clamping structure to form a main wiring harness limiting hole; the branch guide portion 22 has a branch wiring harness limiting hole that constrains the branch wiring harness, and the center line of the branch wiring harness limiting hole is perpendicular to the supporting plane 13. Among them, the main wiring harness direction 6 constrained by the first main guide portion 11 and the branch wiring harness direction 7 constrained by the branch guide portion 22 are perpendicular to each other, and the branch wiring harness direction 7 is perpendicular to the supporting plane 13.

[0031] 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 on 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 together to form a main wire harness limiting hole to fix the main wire harness, so that the wire harness and the tube shell have The larger mating area allows the tube shell to provide protection for the wiring harness, especially for the branch wiring harness, which can avoid the problem of short circuit caused by wear and friction of the wiring harness outer skin, thereby improving the durability of the wiring harness and reducing safety hazards; (4) By making the branch wiring harness limit hole perpendicular to the support plane 13 for fixing the wiring harness, the branch wiring harness in different directions from the support plane 13 can be branched and protected, thereby improving the flexibility of the wiring harness fixing device and the adaptability to wiring harnesses with different functions, meeting the needs of fixing wiring harnesses with different functions, and improving the adaptability of the entire device; at the same time, the support plane can be supported on the vehicle body, and the fixing parts can be integrally constructed or detachably installed on the vehicle body, thereby improving the firmness and reliability of the wiring harness after fixing.

[0032] It should also be noted that since the existing devices that use tube shells to fix the wire harnesses mostly have only one main wire 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 wire harness layout by setting a branch wire harness limiting hole perpendicular to the support plane 13 on the second tube shell, which can reduce the number of wire harness fixing devices used. In addition, this tube shell type wire harness fixing device can also provide good protection for the branching parts of the main wire harness and the branch wire harness, thereby improving the safety performance of the control system.

[0033] 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 branch guide portion 22, and then the second main guide portion 21 is clamped on the first main guide portion 11 to realize the branch fixation of the wiring harness.

[0034] Among them, the main wiring harness limiting hole formed by the two tube shells being clamped together is a circular hole adapted to the wiring harness; the branch wiring harness limiting hole arranged on the branch guide portion 22 is a semicircular hole, so as to facilitate the installation of the branch wiring harness. In this structural manner, the cable tie is used as an auxiliary binding, and a spiral connector 3 is arranged at the branch wiring harness limiting hole, which also has a protective effect on the branch wiring harness. Therefore, the cable tie will not damage the insulation layer of the branch wiring harness.

[0035] In some embodiments, see Figure 1 and Figure 8 As shown, the branch harness limiting hole on the branch guide part 22 is a non-closed hole with a notch, and binding holes 221 are respectively provided on both sides of the notch of the branch guide part 22, and the binding holes 221 are used to pass a cable tie that surrounds the notch. The branch harness limiting hole is a non-closed hole, which is convenient for inserting the branch harness; wherein, the opening direction of the notch on the branch guide part 22 is consistent with the main harness direction 6, and this fixing method of the branch harness, in conjunction with the cable tie to limit the branch harness, is also convenient for installation and disassembly.

[0036] Among them, see Figures 1 to 5 , Figure 8 As shown, a limiting protrusion 222 is also provided at the notch of the branch guide portion 22. The limiting protrusion 222 is provided at the end of the notch closest to the branch guide portion 22 where the branch wire harness is led out, forming a stop and limiting position for the cable tie, thereby preventing the cable tie from scratching the position of the branch wire harness that is not protected by the tube shell. Specifically, three limiting protrusions 222 are evenly distributed along the outer circumference direction of the branch guide portion 22.

[0037] In some embodiments, see Figure 1 , Figure 5 and Figure 8 As shown, a circumferentially surrounding limiting plate 223 is provided in the branching beam limiting hole of the branching guide portion 22. The limiting plate 223 corresponds to the spiral connector 3 that can limit and protect the branching beam along the axial direction of the branching beam limiting hole, and the spiral ribs on the outer circumference of the spiral connector 3 can be stopped by the limiting plate 223, thereby avoiding the risk of the spiral connector 3 coming out of the branching beam limiting hole.

[0038] In some embodiments, Figures 1 to 9As shown, the clamping structure 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, thereby avoiding the risk of the harness being scratched and damaged.

[0039] In some embodiments, Figures 4 to 9 As shown, 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. In 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, and 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 forms an abutment with the side wall of the main clamping groove 55, and the clamping connection is realized.

[0040] In some embodiments, Figures 6 to 9 As shown, the main 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 first clamping claw 51 can realize the position limiting 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 position limiting of the second tube shell 2 and the first tube shell 1 in the direction of the main wiring harness direction 6 and the direction perpendicular to the main wiring harness direction 6.

[0041] 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.

[0042] In some embodiments, see Figures 1 to 7As shown, 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 main card connection structure 5, which can reduce the number of card interfaces provided, thereby reducing the size of the first tube shell 1. wherein the fixing member 4 is provided with a card connection hole 41 which is engaged with the second card protrusion 57.

[0043] Among them, see Figure 4 As shown, 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.

[0044] Of course, the first tube shell 1 is fixed to the fixing member 4 by a clamping method, or can be detachably fixed to the fixing member 4 by bolts, wherein the fixing member can be integrated with the vehicle body or fixed to the vehicle body by clamping or screwing, and the supporting plane can be supported at a certain position of the vehicle body.

[0045] See also Figure 1 , Figure 2 As shown, 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 fixation of the second tube shell 2.

[0046] In some embodiments, Figures 2 to 4 , Figure 6 and Figure 7 As shown, the first main guide portion 11 is further provided with a limiting portion 112, and the limiting portion 112 and the main clamping structure 5 are respectively arranged on both sides of the main wire harness limiting hole, and the outer side of the second main guide portion 21 abuts against the inner side of the limiting portion 112. The limiting portion 112 is a protrusion integrally formed on the first tube shell 1 and protruding toward the second tube shell 2, which forms an echo with the main clamping structure 5 on the opposite side to limit the second tube shell 2.

[0047] Optionally, a thickened portion 212 is further provided on the outer side of the second main guide portion 21, and the radial end surface of the thickened portion abuts against the inner side surface of the limiting portion. The thickened portion 212 increases the mutual contact area at this position, thereby improving the firmness of the limiting portion.

[0048] The first tube shell 1 and the second tube shell 2 are respectively integrally injection-molded injection molded parts. Since they are tube shell structures, they have a certain elasticity. During installation, after the first tube shell 1 is installed and the wiring harness is laid, the first clamping claw 51 of the second tube shell 2 is aligned with the first clamping interface 54, and the fingers are slightly pressed twice from the second tube shell 2 to shrink the second tube shell 2, and the second tube shell 2 is moved toward the first tube shell 1. At the same time, the first clamping claw 51 is clamped to the first clamping interface 54, and the other side of the second tube shell 2 is misaligned with the limiting portion 112 and moves along the inner side of the limiting portion 112 until the end surface of the second tube shell 2 abuts against the end surface of the first tube shell 1. At this time, the second tube shell 2 can be clamped by the limiting portion 112 by releasing the hand.

[0049] During installation, the first clamping claw 51 and the first clamping interface 54 can be clamped first, and then the other side of the second tube shell 2 can be pressed to make the second tube shell 2 elastically shrink and deform until the other side of the second tube shell 2 is clamped into the limiting portion 112, and then the second tube shell 2 can be elastically abutted against the limiting portion 112 under the action of elasticity.

[0050] At this time, if there is no elastic abutment between the second tube shell 2 and the limiting portion 112, the second tube shell 2 may not be limited, so the connection between the second tube shell 2 and the first tube shell 1 will only have one connection point at the clamping position, which obviously cannot ensure the fixation of the wiring harness; therefore, a thickened portion is provided at the position where the second tube shell 2 abuts the limiting portion 112, and the thickness of the thickened portion is greater than the thickness of other positions of the second tube shell 2, so as to ensure the reliability of the elastic abutment of the limiting portion 112 to the position of the thickened portion.

[0051] In some embodiments, see Figures 6 to 9 As shown, the first main guide portion 11 is also provided with a first arc rib 111, and the second main guide portion 21 is provided with a second arc rib 213, and the first arc rib 111 and the second arc rib 213 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 213 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.

[0052] 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.

[0053] Based on the same inventive concept, an embodiment of the present application also provides a vehicle, including the wiring harness fixing device.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. 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.
