[0030] The various aspects of the utility model will be described in detail below by specific embodiments and in conjunction with the drawings.

[0031] Embodiment 1:

[0032] In Figure 1 , Figure 2 , Figure 3In the shown embodiment, a multifunctional sheath structure includes a sheath body 1 integrally injection molded, the sheath body 1 integrally provided with a wire harness running entry end 2 and a tail end 3, the wire harness running entry end is designed with a set running angle α between the axis L and the axis L' of the tail end, the angle α is set between 0 degrees and 180 degrees, and in this embodiment, the angle α is designed as 90 degrees. The sheath body is integrally made by TPU injection molding process.

[0033] The sheath body 1 is internally provided with a wire harness perforation 10 through the wire harness running entry end 2 and the tail end 3.

[0034] In order to avoid deformation between the axis L of the wire harness running entry end and the axis L' of the tail end in the injection molding process, resulting in inaccurate angle and affecting the wire harness running, a deformation prevention structure 4 is arranged on the inner side between the axis of the wire harness running entry end and the axis of the tail end with a set running angle α, and the deformation prevention structure 4 limits the axis of the wire harness running entry end and the axis of the tail end to be in the designed position.

[0035] The deformation prevention structure 4 can adopt a deformation prevention rib structure, a deformation prevention grid structure, a deformation prevention pull rod structure or various other structure forms, as long as it can limit and position the set angle α between the axis of the wire harness running entry end and the axis of the tail end, so as to play a design guiding role for the wire harness and avoid the interference between the wire harness and the vehicle body. In this embodiment, the deformation prevention structure 4 adopts a deformation prevention rib structure.

[0036] The deformation prevention structure 4 is provided with a deformation hole groove 5 at the connection with the sheath body 1, which further reduces the stress concentration phenomenon and ensures the accuracy of the set running of the sheath body 1.

[0037] In order to reduce and transfer the stress concentration of the wire harness in the movement process, a telescopic stress prevention structure 6 is arranged on the tail end 3 coaxially with the tail end 3 of the sheath body 1, the telescopic stress prevention structure 6 is internally provided with a wire running cavity 60, the telescopic stress prevention structure 6 can adopt a mesh sleeve structure, a corrugated sleeve structure or a spiral spring structure, as long as it can reduce the stress concentration phenomenon of the wire harness in the movement process and increase the durability. Figure 5 As shown, in this embodiment, the telescopic stress prevention structure 6 adopts a mesh sleeve structure.

[0038] The telescopic stress prevention structure 6 includes a mesh sleeve connecting body 61, a mesh sleeve elastic body 62 and a mesh sleeve sleeve body 63 which are arranged outwardly from the tail end 3. The inner diameter of the mesh sleeve sleeve body 63 matches the outer diameter of the wire harness, which is used to cooperate with the wire harness and constrain the wire harness.

[0039] To ensure consistency during wire harness assembly and to prevent the sheath body 1 from rotating after assembly, causing a difference from the designed orientation and affecting the product's functionality, an anti-rotation structure 7 is provided on the outside of the sheath body 1. The anti-rotation structure 7 is located on the outside of the tail end of the sheath body 1.

[0040] In this embodiment, the anti-rotation structure 7 includes an anti-rotation groove 71 and an anti-rotation block 72. The anti-rotation groove 71 is circumferentially arranged along the middle position of the outer side of the tail end. The anti-rotation block 72 has a T-shaped structure, extending outward from the bottom of the anti-rotation groove 71 and protruding from the outer circumference of the tail end. The portion of the anti-rotation block 72 protruding from the outer circumference of the tail end is provided with a square anti-rotation surface 73.

In this embodiment, the angle β is 13 degrees. By setting the angle β, the snap-fit ​​position between the snap-fit ​​component and the anti-rotation groove is limited, thereby limiting the set installation position of the sheath body. During use, the anti-rotation function can be effectively realized, limiting the wire harness entry end and tail end to the set direction and preventing rotation.

This mesh sleeve is connected to the caliper motor wiring harness 9 via a sleeve connector 63, and the mesh sleeve elastic body 62 provides deformation protection for the caliper motor wiring harness 9. Because the anti-deformation structure 4 is provided at the entry end 2 and the tail end 3, the axes of the entry end 2 and the tail end 3 are shaped along a predetermined direction, preventing deformation caused by the stress of the caliper motor wiring harness 9 itself, thus avoiding interference with other parts of the vehicle body due to deformation of the sheath after injection molding. Furthermore, the deformation groove 5 at the connection between the anti-deformation structure 4 and the sheath body 1 effectively reduces the risk of stress concentration deformation during the injection molding process.

[0044] In use, the clamping piece 100 is fixedly connected with the vehicle body panel 200. Specifically, the clamping piece 100 is provided with a semi-annular clamping groove 101, the semi-annular clamping groove 101 is clamped in the anti-rotation groove 71, the position of the sheath body 1 is limited according to the wire harness setting wire direction (the direction indicated by the arrow in the figure is the wire harness wire direction), and the sheath body is prevented from rotating, at the same time, the anti-rotation block 72 abuts against the vehicle body panel 200, and further prevents rotation limiting.

[0045] After being installed on the vehicle, the position of the sheath body 1 is limited by the anti-rotation structure 7 to prevent rotation, which ensures the consistency of the wire harness assembly, avoids the difference between the design and the assembly after rotation, and thus avoids the influence on the product use function.
