Figure 2 The orientation or positional relationship shown is for illustrative purposes only and is not intended to 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 should not be construed as a limitation of this application.

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. The described embodiments should not be regarded as limitations on this application. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] In the description of the embodiments of this application, technical terms such as "first," "second," and "third" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0020] Unless otherwise defined, all technical and scientific terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in the embodiments of this application is for the purpose of describing the embodiments of this application only and is not intended to limit this application.

[0021] One embodiment of this application provides a wire harness fixing bracket; please refer to [link / reference]. Figure 2 and Figure 3 The wire harness fixing bracket includes a bracket body 10 and a wire fixing bracket 20.

[0022] Please see Figure 1 The support body 10 has a main line channel 10a and a branch line channel 10b on one side. One end of the branch line channel 10b is connected to the main line channel 10a. A wire passage space 10c is formed on the side of the support body 10 away from the main line channel 10a.

[0023] The wire fixing bracket 20 is disposed on the side of the bracket body 10 near the wire passage space 10c, and the wire fixing bracket 20 has a wire harness fixing hole 20a facing the wire passage space 10c.

[0024] Specifically, the main cable tray 10a and the branch cable tray 10b are located on the same side of the bracket body 10. The main cable tray 10a can accommodate a main cable harness, thus serving to fix and constrain the main cable harness. The branch cable tray 10b can accommodate a branch cable harness 70, thus serving to fix and constrain the branch cable harness 70. Therefore, by setting the branch cable tray 10b, it is easier for the branch cable harness 70 to connect with the main cable harness, which can reduce the problems of vibration loosening, bending wear, and poor adaptability to complex layouts of the branch cable harness 70, thereby improving the overall reliability and installation efficiency of the cable harness fixing bracket.

[0025] Depending on the actual situation, the extension direction of the branch channel 10b can be completely different from that of the main channel 10a, or the extension direction of the branch channel 10b at the junction with the main channel 10a can be different, while the extension direction of other parts of the area can be the same.

[0026] The specific dimensions of the main cable channel 10a can be set according to the actual situation. For example, the channel width of the main cable channel 10a is 30mm, which can accommodate main cable harnesses with diameters of 5mm-26mm, such as 5mm, 20mm or 26mm.

[0027] The branch cable tray is smaller than the main cable tray 10a, and its specific shape and size can be set according to the actual situation. For example, the branch cable tray 10b has an arc-shaped cross-section. That is to say, the branch cable tray 10b is an arc-shaped tray with a partially open area and adopts an arc-shaped cross-section, which can provide a better support effect for the branch cable harness 70 while facilitating the installation of the branch cable harness 70.

[0028] For example, the branch channel 10b is an arc-shaped guide structure with a diameter of 8mm, which can accommodate branch and trunk wire harnesses 70 with diameters of 3mm-8mm, such as 3mm, 5mm or 8mm.

[0029] For example, the junction of the branch channel 10b and the main channel 10a is smoothly transitioned.

[0030] In other words, there are no obvious abrupt changes (such as folds or sharp protrusions) at the junction of the branch channel 10b and the main channel 10a; the transition is smooth. For example, a rounded surface transition can be used.

[0031] On the side of the support body 10 away from the main cable channel 10a, the support body 10 also forms a cable passage space 10c. This allows another main cable bundle to pass through.

[0032] The cable support 20 and the support body 10 can be integrally formed or separately formed.

[0033] The wire fixing bracket 20 and the wire passage space 10c are located on the same side of the bracket body 10. By providing wire harness fixing holes 20a on the wire fixing bracket 20, it can be used to cooperate with a fixing component to fix the main wire harness passing through the wire passage space 10c. Thus, the wire harness fixing bracket can fix multiple main wire harnesses.

[0034] The wire harness fixing hole 20a of the wire bracket 20 faces the wire passage space 10c, which makes it easy for the wire bracket 20 to fix the main wire harness in the wire passage space 10c.

[0035] The specific shape and size of the wire harness fixing hole 20a can be set according to the actual situation. For example, the wire harness fixing hole 20a can be a slotted hole. The slotted hole setting method can facilitate the fixing of the main wire harness within the wire passage space 10c.

[0036] For example, the extension direction of the wire harness fixing hole 20a is perpendicular to the extension direction of the main wire channel 10a, so that the wire fixing bracket 20 can fix the main wire harness in the wire passage space 10c.

[0037] For example, the size of the wire harness fixing hole 20a is 7mm x 12mm, which can be used to fit main wire harnesses with diameters of 5mm-20mm, such as 5mm, 10mm or 20mm.

[0038] It should be noted that the specific materials for the wire harness fixing bracket can be selected according to the conditions of the surrounding components.

[0039] For example, the material of the wire harness fixing bracket is PA6-GF15 (an engineering plastic material with polyamide 6 / nylon 6 as the base material and 15% glass fiber reinforcement). This reduces the weight of the wire harness fixing bracket while improving its wire securing effect.

[0040] Another embodiment of this application provides a vehicle including the wiring harness fixing bracket described in any embodiment of this application. The vehicle includes a first main wiring harness 60, a branch wiring harness 70, and a second main wiring harness 80. The first main wiring harness 60 is disposed in a main cable channel 10a, the branch wiring harness 70 is disposed in a branch cable channel 10b, and the second main wiring harness 80 passes through a cable passage space 10c and is fixed to a wiring harness fixing hole 20a by a fixing member. Thus, the wiring harness fixing bracket can simultaneously constrain the first main wiring harness 60, the branch wiring harness 70, and the second main wiring harness 80, giving the wiring harness fixing bracket a better cable securing effect.

[0041] In the wire harness fixing bracket of this application, the wire harness fixing bracket includes a bracket body 10 and a wire fixing bracket 20. One side of the bracket body 10 has a main wire channel 10a and a branch wire channel 10b, with one end of the branch wire channel 10b communicating with the main wire channel 10a. A wire-passing space 10c is formed on the side of the bracket body 10 away from the main wire channel 10a. The wire fixing bracket 20 is disposed on the side of the bracket body 10 near the wire-passing space 10c, and the wire fixing bracket 20 has a wire harness fixing hole 20a facing the wire-passing space 10c. That is, the wire harness fixing bracket can install a first main wire harness 60 through the main wire channel 10a, allow a second main wire harness 80 to pass through the wire-passing space 10c and be fixed by the wire fixing bracket 20, and simultaneously install a branch wire harness 70 through the branch wire channel 10b. Therefore, branch harnesses 70 and multiple main harnesses can be fixed simultaneously, avoiding the need to set up multiple harness fixing brackets to fix different harnesses separately. This reduces the installation space occupied, improves the compactness of the harness layout, and makes the harness fixing bracket of this application have a better wire fixing effect.

[0042] In one embodiment, please refer to Figures 1 to 3The wire harness fixing bracket also includes a first mounting bracket 30 and a second mounting bracket 40 disposed on the bracket body 10. The first mounting bracket 30 includes a first mounting surface 30a with a first mounting hole 30b, and the second mounting bracket 40 includes a second mounting surface 40a with a second mounting hole 40b. The first mounting surface 30a and the second mounting surface 40a are located on the side of the bracket body 10 away from the main cable channel 10a. By all mounting brackets and wire fixing brackets 20 being disposed on the same side of the bracket body 10, the wire harness fixing bracket can fix the main wire harness in the cable passage space 10c while also reducing the overall space occupied by the wire harness fixing bracket.

[0043] Specifically, the first mounting bracket 30 and the bracket body 10 can be a one-piece molded structure or a separate molded structure. The second mounting bracket 40 and the bracket body 10 can be a one-piece molded structure or a separate molded structure.

[0044] The first mounting bracket 30 and the second mounting bracket 40 are bracket structures for connecting with other surrounding structures (such as structures in a vehicle for mounting wire harness fixing brackets).

[0045] The first mounting hole 30b is a connection hole on the first mounting bracket 30 for connecting with other surrounding structures. The second mounting hole 40b is a connection hole on the second mounting bracket 40 for connecting with other surrounding structures.

[0046] It should be noted that the formation method of the line space 10c is not limited.

[0047] For example, a wire passage space 10c is formed between the first mounting bracket 30, the second mounting bracket 40 and the bracket body 10.

[0048] The specific shapes of the first mounting hole 30b and the second mounting hole 40b are not limited.

[0049] For example, the first mounting hole 30b is an oblong hole for engaging with other surrounding structures, and the second mounting hole 40b is a circular fastening hole for securely connecting with other surrounding structures. Thus, by combining fastening and engagement, the wire harness is rigidly locked to surrounding components, forming a mechanical balance constraint to suppress vibration transmission and significantly reduce the amount of wire harness movement.

[0050] The size of the first mounting hole 30b is not limited, such as a 7mm x 12mm oblong hole.

[0051] The size of the second mounting hole 40b is not limited, such as a round hole with a diameter of 7mm.

[0052] In one embodiment, please refer to Figure 2 and Figure 3The first mounting surface 30a and the bracket body 10 are spaced apart along a first direction, and the distance between the first mounting surface 30a and the bracket body 10 along the first direction is called the first distance. The distance between the second mounting surface 40a and the bracket body 10 along the first direction is called the second distance, and the first distance is greater than or less than the second distance. That is to say, the distances between the first mounting surface 30a and the second mounting surface 40a and the bracket body 10 are not the same. As a result, the rigidity of the wire harness fixing bracket is stronger and the connection stability is better.

[0053] It should be noted that the specific values ​​of the first and second spacing can be set according to the actual situation.

[0054] For example, the first spacing is 40mm. This facilitates the main wire harness being threaded through the wire passage space 10c.

[0055] In one embodiment, please refer to Figure 1 The first mounting bracket 30 is disposed on one side of the bracket body 10 along the second direction, and the second mounting bracket 40 is disposed on one side of the bracket body 10 along the extension direction of the main cable channel 10a. The second mounting bracket 40 is inclined along the second direction towards the side opposite to the first mounting bracket 30, so that the second mounting surface 40a is located on the side of the bracket body 10 along the second direction opposite to the first mounting bracket 30, and the second direction is perpendicular to the extension direction of the main cable channel 10a. Therefore, this asymmetrical fixing method improves the connection stability between the wire harness fixing bracket and the surrounding structure.

[0056] In other words, from the second direction (i.e., the direction perpendicular to the extension direction of the main cable channel 10a), the first mounting surface 30a and the second mounting surface 40a are located on opposite sides of the bracket body 10 along the second direction, rather than on the same side, thus improving the connection stability between the wire harness fixing bracket and the surrounding structure.

[0057] Furthermore, the second mounting bracket 40 is located on one side of the bracket body 10 along the extension direction of the main cable channel 10a, which can avoid the main cable bundle passing through the cable passage space 10c, so as to fix it on the cable fixing bracket 20.

[0058] In one embodiment, please refer to Figure 4 and Figure 5 The wire harness fixing bracket also includes a third mounting bracket 50 disposed on the bracket body 10. The third mounting bracket 50 includes a third mounting surface 50a with a third mounting hole 50b. The distances between the first mounting surface 30a, the second mounting surface 40a and the bracket body 10 are different.

[0059] In other words, the wire harness fixing bracket has three mounting brackets, giving it three fixed connection points. This greatly improves the connection stability between the wire harness fixing bracket and other surrounding structures, while also preventing the wire harness fixing bracket from becoming too complex.

[0060] The distances between the first mounting surface 30a, the second mounting surface 40a, and the bracket body 10 are all different, which can further improve the installation stability of the wire harness fixing bracket.

[0061] In one embodiment, please refer to Figure 4 and Figure 5 The third mounting bracket 50 is located on the side of the bracket body 10 away from the first mounting bracket 30 along the second direction, which is perpendicular to the extension direction of the main channel 10a.

[0062] In other words, the third mounting bracket 50 and the first mounting bracket 30 are located on opposite sides of the bracket body 10 along the second direction, thereby making the fixing method of the wire harness fixing bracket more stable.

[0063] In one embodiment, please refer to Figure 1 A portion of the wall of the main cable channel 10a near the cable passage space 10c is penetrated to form a cable tie hole 10d. The cable tie hole 10d allows cable ties to pass through, so as to fix the main cable harness passing through the main cable channel 10a to the cable harness fixing bracket.

[0064] It should be noted that the number and arrangement of the 10d cable tie holes can be set according to the actual situation.

[0065] For example, on both sides of the main cable channel 10a along the extension direction, the cable harness fixing bracket has two cable tie holes 10d spaced apart along the second direction, which makes it easy to fix the main cable harness on the cable harness fixing bracket.

[0066] For example, the 10d binding hole of the cable tie is a 3mm x 8mm square hole.
