[0022] 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.

[0023] 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.

[0024] In the claims, specification and the above-mentioned drawings of the utility model, the term "inside" refers to the inner side of the wiring harness groove of the protective shell body, and "outside" refers to the outer side of the wiring harness groove of the protective shell body. This is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it cannot be understood as limiting the specific protection scope of the present invention.

[0025] In the claims, specification and drawings of the present utility model, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0026] Please also read Figure 1 and Figure 2 The wire harness protective shell provided by the utility model is now described. The wire harness protective shell comprises a protective shell body, two ends of which are respectively provided with a bolt fixing structure 5 and a movable clamping structure 11, and a first fixed clamping structure 13 is also provided on the protective shell body, and the connecting line of the bolt fixing structure 5, the movable clamping structure 11 and the first fixed clamping structure 13 forms a triangle shape.

[0027] The wiring harness protective shell provided by the utility model is provided with a bolt fixing structure 5 at one end of the protective shell body, and one end of the protective shell body is first fixed to the vehicle body by means of the bolts, and then the protective shell body is clamped and fixed to the vehicle body at the position of the first fixed clamping structure 13 along the preset wiring harness direction, and finally the other end of the protective shell body is passed through the movable clamping structure 11 to eliminate the accumulated assembly tolerance when assembling the protective shell body.

[0028] Therefore, the wiring harness protective shell provided in the present application adopts a multi-point fixing method for the wiring harness protective shell, and adopts a fixing method that combines fixed points, clip-on fixed points and movable clip-on points. Through the coordinated installation method of bolt fixing, movable clip-on and fixed clip-on, it can eliminate assembly tolerance and improve the fault tolerance of assembly, thereby reducing the requirements for the assembly dimensional accuracy of the vehicle body, and is also beneficial to improving the efficiency of processing and manufacturing, while improving the stability and smoothness of assembly; the lines connecting the three points of bolt fixing, movable clip-on and fixed clip-on form a triangle shape, which also ensures the stability of the assembly of the wiring harness protective shell.

[0029] Specifically, the bolt fixing structure 5 serves as a non-adjustable positioning point to firmly fix one end of the protective shell body on the vehicle body, and then the protective shell body is arranged along the preset wiring harness, and the assembly tolerance is adjusted toward the other end of the protective shell body until it is fixedly snapped into position at the first fixed snap-fit ​​structure 13. The final assembly tolerance is eliminated through the movable snap-fit ​​structure 11, thus avoiding the problem of being unable to assemble due to errors in manufacturing accuracy.

[0030] In some embodiments, see Figure 1 and Figure 2 The bolt fixing structure 5 includes a bolt fixing portion 501 integrally formed on the outer side of the first side wall 6 of the protective shell body, and a first mounting hole 502 is provided on the bolt fixing portion 501; the movable clamping structure 11 includes a second mounting hole 111 provided on the second side wall 12 of the protective shell body; the center line of the first mounting hole 502 is perpendicular to the center line of the second mounting hole 111. The effects of this embodiment are reflected in three aspects. First, the bolt fixing structure 5 and the movable snap-fit ​​structure 11 are located at both ends of the protective shell body, and are also arranged on the two side walls of the protective shell body, forming a diagonal fixing mode to ensure the stability of the protective shell body after assembly; second, the center line of the first mounting hole 502 is perpendicular to the center line of the second mounting hole 111, which is reflected in the different installation directions of the bolt fixing structure 5 and the movable snap-fit ​​structure 11, that is, the bolt passing through the first mounting hole 502 and the movable snap-fit ​​structure 113 passing through the second mounting hole 111 have different installation directions. Different installation directions are more conducive to eliminating assembly tolerances; third, it can be seen that the first mounting hole 502 and the second mounting hole 111 are not at the bottom of the groove of the protective shell body (the wiring harness groove formed by the protective shell body has a groove bottom and a first side wall 6 and a second side wall 12 arranged on both sides of the groove bottom), which can also avoid the risk of scratching and wearing the wiring harness by the bolts and the movable snap-fit ​​113.

[0031] Furthermore, the bolt fixing structure 5 also includes a bolt passing through the first mounting hole 502, and one end of the protective shell body is fixed to the vehicle body by the bolt; since the protective shell body is generally an integral injection-molded component, in order to avoid wear of the bolt on the plastic component, a wear-resistant sleeve can be embedded in the first mounting hole 502 as the first mounting hole 502, and the wear-resistant sleeve can be a copper sleeve, a polyethylene sleeve or a steel sleeve, etc.; in addition, the first mounting hole 502 does not need to be processed with an internal thread.

[0032] The movable snap-fit ​​structure 11 serves to adjust the assembly tolerance and also includes an movable snap 113. The movable snap 113 is snapped onto the second mounting hole 111. The movable snap 113 is provided with multiple layers of inverted conical snapping claws along its snapping direction. The inverted conical snapping claws of different layers are snapped onto the holes on the vehicle body to achieve coordination with different assembly tolerances, thereby eliminating the assembly tolerance.

[0033] The vehicle body is provided with holes for connection with bolts, movable buckles 113 and fixed buckles, and the names of the holes are not distinguished one by one in this article.

[0034] In some embodiments, see Figure 1 and Figure 2The second side wall 12 of the protective shell body forms an outwardly protruding avoidance groove 112 at the position of the second mounting hole 111, and the second mounting hole 111 is disposed in the avoidance groove 112. By forming the outwardly protruding avoidance groove 112 on the second side wall 12, the end cap of the active buckle 113 can be hidden in the avoidance groove 112, thereby avoiding the risk of direct contact between the active buckle 113 and the wiring harness, abrasion of the wiring harness, and affecting the electrical function of the entire vehicle.

[0035] In some embodiments, see Figure 1 and Figure 2 The first fixed clamping structure 13 includes a third mounting hole 132 disposed on the second side wall 12 of the protective shell body. The first fixed clamping structure 13 serves as the middle clamping point of the protective shell body, which ensures the stable assembly of the protective shell body, thereby avoiding the risk of the middle part of the protective shell body warping and ensuring the stability of the assembly of the protective shell body.

[0036] Furthermore, the first fixing clamping structure 13 further includes a first fixing buckle 131 , which is installed on the third mounting hole 132 and clamps the protective shell body and the vehicle body together.

[0037] Due to the complexity of the wiring harness direction and the complexity of the wiring harness, the protective shell body designed in the present application has an arc-shaped bend, so the first side wall 6 and the second side wall 12 are both arc-shaped bends. In the figure, the bending radius of the first side wall 6 is smaller than the bending radius of the second side wall 12.

[0038] In some embodiments, see Figure 1 and Figure 2 The outer side of the first side wall 6 of the protective shell body is also provided with a staggered clamping structure 7, which includes a staggered clamping portion 701 integrally formed on the outer side of the first side wall 6, and two groups of staggered clamping joints 702 are provided on the staggered clamping portion 701; the staggered clamping structure 7 is staggered with the first fixed clamping structure 13. The two staggered clamping structures 7 are staggered and cooperate with the first side wall 6, which can achieve the rationalization and stability of the direction of the protective shell body and avoid interference with surrounding components.

[0039] Furthermore, each group of card connectors 702 has two in number, and bending hooks are provided at the ends of the card connectors 702. The bending hooks of each group of card connectors 702 are arranged opposite to each other. When two card connectors 702 are inserted into two side-by-side card interfaces, the bending hooks are first deformed by pressure and pass through the card interfaces and then reset to be connected with the vehicle body.

[0040] At the same time, the staggered snap-fitting structures 7 are arranged closely together with zero gap, and the staggered arrangement with the first fixed snap-fitting structure 13 can form a small triangle shape after connecting the three points, thereby improving the assembly stability of the middle part of the protective shell body and further improving the stability of the protective shell body after assembly.

[0041] In some embodiments, see Figure 1 and Figure 2 The protective shell body is also provided with a second fixing clamping structure 4, which is located at the same end of the protective shell body as the bolt fixing structure 5, and the second fixing clamping structure 4 and the bolt fixing structure 5 are located on both sides of the same end of the protective shell body. The bolt fixing structure 5 fixes one end of the protective shell body, and cooperates with the second fixing clamping structure 4 to ensure the firmness of fixing one end of the protective shell body.

[0042] At the same time, the present application only uses bolts at one position, and the other positions are fixed by snap-fitting, which can reduce the tediousness of assembling the protective shell body and reduce the workload of assembly, because snap-fitting does not require tools and can be done manually.

[0043] In some embodiments, see Figure 1 and Figure 2 The second fixed clamping structure 4 includes a fourth mounting hole, and the center line of the fourth mounting hole is parallel to the center line of the first mounting hole 502. The second fixed clamping structure 4 also includes a second fixed buckle installed on the fourth mounting hole. The second fixed buckle and the bolts firmly fix one end of the protective shell body on the vehicle body at both sides of the protective shell body, and form a two-point positioning for the protective shell body to realize the anti-rotation constraint of the protective shell body.

[0044] In some embodiments, see Figure 1 and Figure 2 Multiple wire outlet grooves are respectively arranged at both ends of the protective shell body, and the outlets of the multiple wire outlet grooves are respectively oriented in different directions, which can achieve good wiring harness integration and multiple collection functions to meet the needs of complex wiring harness layout of the entire vehicle.

[0045] At the same time, the main functions of the wiring harness outlet are concentrated at the two ends of the protective shell body. The two ends of the protective shell body are provided with a movable clamping structure 11 and a bolt fixing structure 5 to ensure the stability of the wiring harness layout.

[0046] Furthermore, the wiring harness groove of the protective shell body is designed along the wiring harness arrangement direction, and the cross-section is an irregular arc-shaped groove. Specifically, the arc-shaped groove formed in the middle part of the wiring harness groove has a smaller width, a small cross-sectional area, and a narrow space. Therefore, it can play a role in restraining the wiring harness in the narrow space groove; the wiring harnesses need to be dispersed at both ends of the protective shell body, so the space is wider, which is convenient for separating the wiring harnesses of different functions and leading them out from the outlet grooves in different directions.

[0047] In some embodiments, see Figure 1 and Figure 2The outlet groove includes a first direction outlet groove 1, a second direction outlet groove 2 and a third direction outlet groove 3 at the same end as the bolt fixing structure 5. The distances from the first direction outlet groove 1, the second direction outlet groove 2 and the third direction outlet groove 3 to the bolt fixing structure 5 increase successively, and the second fixed clamping structure 4 is arranged between the second direction outlet groove and the third direction outlet groove 3. As a fixed end, the second fixed clamping structure 4 is arranged between the two outlet grooves of the protective shell body, which can firmly limit the wire harness in the direction of the outlet groove, ensuring the stability of the wire harness outlet at this end.

[0048] Furthermore, three outlet grooves in different directions are respectively arranged at both ends of the protective shell body. The outlet grooves at one end of the movable clamping structure 11 are respectively the fourth direction outlet groove 8, the fifth direction outlet groove 9 and the sixth direction outlet groove 10. The outlet grooves are hierarchically differentiated, that is, the bottoms of the outlet grooves are not in the same plane, which perfectly avoids the problem of mutual interference.

[0049] The structural integration design with the cable ducts concentrated at both ends of the protective shell body is also conducive to the reasonable layout of the wiring harness and the pipelines of the whole vehicle, and avoids interference with surrounding components, ensuring the reasonable layout of the wiring harness and pipelines and the stability of assembly.

[0050] Therefore, the present application concentrates the main functions of the wiring harness at both ends of the wiring harness protective shell; combines the design of movable clamping, fixed clamping and bolt fixing to eliminate assembly tolerance and ensure assembly stability; the staggered clamping structure 7 realizes the layout and functional integration of the wiring harness and the whole vehicle pipeline; the hierarchical design of the outlet groove perfectly avoids the interference problem. The overall design realizes the reasonable layout of the wiring harness function, integrates the whole vehicle pipeline function, and avoids interference with surrounding components.

[0051] It should also be noted that, see Figure 3 As shown, a reinforcing rib 14 is further provided on the side of the protective shell body facing away from the wiring harness slot to enhance the structural strength of the protective shell body. The reinforcing rib 14 can be designed in various forms. For example, the length direction of the reinforcing rib 14 can be arranged along the direction of the wiring harness of the protective shell body; the reinforcing rib 14 can also be an arc-shaped structure surrounding the protective shell body, and the reinforcing rib 14 can also be provided at the position where each wire outlet slot connects with the protective shell body, which are no longer marked one by one in the figure.

[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, which adopts the wiring harness protective shell.

[0054] The vehicle provided by the embodiment of the utility model adopts a variety of fixed structure matching forms, which can eliminate assembly tolerances, improve the fault tolerance of assembly, and reduce the requirements for the assembly dimensional accuracy of the vehicle body, which is beneficial to improving the efficiency of processing and manufacturing, reducing processing costs, and at the same time improving the stability and smoothness of assembly; the three-point connection of bolt fixing, movable clamping and fixed clamping forms a triangular shape, which also ensures the stability of the wiring harness protective shell assembly.

[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.
