[0031] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] like Figure 1-Figure 6As shown, the present invention provides a corrugated pipe positioning device, which is used to position and install the corrugated pipe 200 of the main wiring harness of the vehicle. The corrugated pipe positioning device includes a positioning member 1 and a mounting bracket 2. The positioning member 1 is formed by buckling an upper cover 11 and a lower cover 12. The positioning member 1 is a tubular structure. After the upper cover 11 and the lower cover 12 are buckled together, a accommodating space for accommodating the corrugated pipe 200 is formed, so that the positioning member 1 can be sleeved on the outside of the corrugated pipe 200. The inner side wall of the positioning member 1 is provided with a positioning portion, which is used to cooperate with the corrugated structure of the corrugated pipe 200, and the outer side wall of the positioning member 1 forms a limiting groove 16. The mounting bracket 2 is clamped in the limiting groove 16, and the mounting bracket 2 is used to fix the positioning member 1 to the frame 100. The bellows positioning device of this embodiment sets a positioning portion of the tubular structure positioning member 1 to cooperate with the corrugated structure of the bellows 200, and at the same time sets a limiting groove 16 on the outer side of the positioning member 1, and the mounting bracket 2 is clamped in the limiting groove 16, and the positioning member 1 is fixedly connected to the frame 100 through the mounting bracket 2. During the assembly process, the relative position relationship between the positioning member 1 and the bellows 200 does not change, the position relationship of the mounting bracket 2 relative to the positioning member 1 does not change, and then the position relationship of the bellows 200 relative to the frame 100 does not change, thereby ensuring the positioning accuracy of the bellows 200 after installation.

[0033] Furthermore, if Figure 2-Figure 4 As shown, in order to facilitate processing and manufacturing and reduce production costs, the upper cover 11 and the lower cover 12 have the same structure, and the cross-sectional shape of the upper cover 11 and the lower cover 12 are both semicircular. After the upper cover 11 and the lower cover 12 are buckled, the cross-sectional shape is a complete circle. The upper cover 11 and the lower cover 12 are respectively provided with a first clamping portion 17 and a second clamping portion 18 on both sides, and the first clamping portion 17 is clamped and connected with the second clamping portion 18. Specifically, the first clamping portion 17 of the upper cover 11 is clamped and connected with the second clamping portion 18 of the lower cover 12, and the first clamping portion 17 of the lower cover 12 is clamped and connected with the second clamping portion 18 of the upper cover 11. In other embodiments, the upper cover 11 and the lower cover 12 can also be provided with threaded holes, and the two are connected by threaded connection.

[0034] Specifically, the first clamping portion 17 is a clamping protrusion, and the second clamping portion 18 is a clamping slot. The clamping protrusion and the clamping slot are clamped together, and a chamfer is provided on one side of the clamping protrusion facing the clamping slot to facilitate clamping assembly.

[0035] Furthermore, both ends of the upper cover 11 and the lower cover 12 are provided with limiting protrusions 15. Since the structures of the upper cover 11 and the lower cover 12 are the same, for the sake of simplicity, only the upper cover 11 will be described as an example, and the structure of the lower cover 12 will not be repeated. The limiting protrusions 15 are continuously arranged along the circumference of the upper cover 11, that is, the limiting protrusions 15 at both ends of the upper cover 11 are semi-annular structures. After the upper cover 11 and the lower cover 12 are buckled, the limiting protrusions 15 corresponding to each other form an annular structure, so that the limiting groove 16 of the positioning part is formed between the limiting protrusions 15 of the two annular structures, and the two inner side walls of the limiting groove 16 are the side walls of the limiting protrusions 15 of the two annular structures facing the limiting groove 16. There are two first clamping parts 17 and two second clamping parts 18 on the upper cover 11, and the two limiting protrusions 15 are each provided with a first clamping part 17 and a second clamping part 18, so that the upper cover 11 and the lower cover 12 are connected through the four-point clamping structure, and the connection is more reliable.

[0036] Furthermore, if Figure 2-Figure 4 As shown, the positioning part includes a first positioning part 13 and a second positioning part 14, the first positioning part 13 is a groove structure and is used to cooperate with the protrusion of the corrugated structure, the second positioning part 14 is a protrusion structure and is used to cooperate with the groove of the corrugated structure, and the first positioning part 13 and the second positioning part 14 are arranged at intervals along the length direction of the positioning member 1. The corrugated structure outside the corrugated tube 200 of the vehicle main wiring harness is usually a plurality of staggered annular protrusions and annular grooves, so that the first positioning part 13 and the second positioning part 14 respectively cooperate with the corresponding annular protrusions and annular grooves on the corrugated tube 200 to ensure that the relative position of the positioning member 1 and the corrugated tube 200 does not change. Similarly, the upper cover 11 and the lower cover 12 have the same structure, so both the upper cover 11 and the lower cover 12 are provided with a first positioning portion 13 and a second positioning portion 14. After the upper cover 11 and the lower cover 12 are buckled together, the corresponding first positioning portion 13 and the second positioning portion 14 jointly form an annular groove structure and an annular protrusion structure, and are used to cooperate with the corrugated structure of the bellows 200.

[0037] Optionally, after the upper cover 11 and the lower cover 12 are buckled, in order to further ensure that the relative position of the positioning member 1 and the bellows 200 does not change, the first positioning portion 13 and the second positioning portion 14 are both provided in plurality, and the plurality of first positioning portions 13 and the plurality of second positioning portions 14 are staggered along the length direction of the positioning member 1. By staggering the plurality of first positioning portions 13 and the second positioning portions 14, the positioning and matching between the positioning member 1 and the bellows 200 is more reliable, further ensuring that the relative position relationship between the positioning member 1 and the bellows 200 does not change.

[0038] Furthermore, if Figure 1 and Figure 5As shown, the mounting bracket 2 includes a matching portion 21, a first mounting portion 22 and a second mounting portion 23. The matching portion 21 is sleeved in the limiting groove 16 and the two sides are respectively fitted with the two side walls of the limiting groove 16. The first mounting portion 22 and the second mounting portion 23 are respectively connected to the two ends of the matching portion 21, and the first mounting portion 22, the matching portion 21 and the second mounting portion 23 are integrated. The first mounting portion 22 and the second mounting portion 23 are both provided with mounting holes, and the fasteners are fixedly connected to the frame 100 through the mounting holes of the first mounting portion 22 and the second mounting portion 23. After the mounting bracket 2 is installed to the frame 100, axial movement between the positioning member 1 and the mounting bracket 2 is avoided. The mounting hole on one of the first mounting portion 22 and the second mounting portion 23 is a round hole, and the mounting hole on the other is a long hole or an oblong hole, and the length direction of the long hole or the oblong hole is perpendicular to the length direction of the mounting bracket 2. In this embodiment, the mounting hole on one of the first mounting portion 22 and the second mounting portion 23 that is away from the frame 100 is set as a long hole or an oblong hole and is used for adjustment, and the mounting hole on the other is set as a round hole and is used for positioning and connecting with the frame 100. During the installation process, the first mounting portion 22 and the second mounting portion 23 are first separated, and the matching portion 21 is sleeved on the positioning member 1 and matched with the limiting groove 16; the first mounting portion 22 or the second mounting portion 23 with the long hole or the oblong hole is adjusted so that the matching portion 21 is pressed against the bottom wall of the limiting groove 16, and then the mounting bracket 2 is fixedly mounted on the frame 100 by fasteners. In this way, the friction between the matching portion 21 and the positioning member 1 is increased, and the positioning member 1 is prevented from rotating relative to the mounting bracket 2. Optionally, in order to prevent the mounting bracket 2 from rotating relative to the frame 100, the mounting holes on the first mounting portion 22 and the second mounting portion 23 can be set to two, and the rotation is prevented by connecting at two points.

[0039] Furthermore, if Figure 1 and Figure 6 As shown, the corrugated tube positioning device also includes a fixing bracket 3, the fixing bracket 3 includes a first fixing portion 31, a second fixing portion 32 and a connecting portion 33, the first fixing portion 31 and the second fixing portion 32 are connected by the connecting portion 33, and the first fixing portion 31, the connecting portion 33 and the second fixing portion 32 are integrally arranged. The first fixing portion 31 and the second fixing portion 32 are arranged at intervals in a direction perpendicular to the frame 100, the first fixing portion 31 is fixedly connected to the mounting bracket 2, and the second fixing portion 32 is fixedly connected to the frame 100. By setting the fixing bracket 3, there is a certain interval between the mounting bracket 2 and the frame 100, that is, there is a certain interval between the positioning member 1 and the corrugated tube 200 and the frame 100, so as to avoid interference between components during wiring.

[0040] Specifically, when the main wiring harness with the corrugated tube 200 is positioned and installed using the bellows positioning device in this embodiment, a number of wiring harness positioning points are first selected on the corrugated tube 200 of the main wiring harness, and the upper cover 11 and the lower cover 12 are buckled and firmly connected at each wiring harness positioning point, and then the frame 100 positioning points corresponding to the wiring harness positioning points on the bellows 200 are determined on the frame 100, and the fixing brackets 3 are respectively installed on the frame 100 positioning points, and finally the mounting bracket 2 is sleeved in the limiting groove 16 of the positioning member 1, and the mounting bracket 2 is fixedly connected to the fixing bracket 3, so that the relative positions of each wiring harness positioning point of the bellows 200 and the frame 100 are uniquely determined, thereby ensuring the positioning and installation accuracy of the main wiring harness, and being able to ensure a firm installation to avoid axial movement.

[0041] The present invention also provides a commercial vehicle, including the bellows positioning device in this embodiment. By setting the bellows positioning device in this embodiment, the positioning accuracy during the wiring harness assembly process is guaranteed, and the positioning accuracy of the wiring harness is highly consistent.
