[0042] To make the purpose, technical solutions and advantages of the present disclosure clearer, the following will further describe the embodiments of the present disclosure in detail with reference to the drawings.

[0043] This embodiment relates to a wire harness fixing bracket, as Figure 1 shown in the structural schematic diagram of the wire harness fixing bracket, Figure 2 shown in the front view structural schematic diagram of the wire harness fixing bracket, Figure 3 shown in the rear view structural schematic diagram of the wire harness fixing bracket, Figure 4 shown in the top view structural schematic diagram of the wire harness fixing bracket, Figure 5 shown in the structural schematic diagram of the connection between the wire harness fixing bracket and the engine body 3, Figure 6The figure shows a rear view structural schematic diagram of the wire harness fixing bracket connected to the engine body 3. Figure 7 The figure shows a top view structural schematic diagram of the wire harness fixing bracket connected to the engine body 3. Figure 8 The figure shows a side view structural schematic diagram of the wire harness fixing bracket connected to the engine body 3. Figure 9 The figure shows a structural schematic diagram of the restraint member 5 and the mounting structure 6. Figure 10 The figure shows a front view structural schematic diagram of the restraint member 5 and the mounting structure 6.

[0044] Reference Figures 1 to 4 As shown, the wire harness fixing bracket includes a bracket body 1, and the bracket body 1 has a main guiding cavity 11 and an auxiliary mounting groove 12. Among them, the main guiding cavity 11 extends through along the first direction, and as Figure 5 shown, the main guiding cavity 11 is suitable for installing the internal wire harness 2. For example, the internal wire harness 2 can extend inside the main guiding cavity 11 along the first direction. And the first direction is the length direction of the bracket body 1.

[0045] Continue to refer to Figure 5 and in combination with Figure 1 shown, the auxiliary mounting groove 12 is suitable for sleeving on the protruding part 31 of the engine body 3 and cooperating with the protruding part 31. For example, the auxiliary mounting groove 12 can be in clearance fit with the protruding part 31. Among them, the cross-sectional shape of the auxiliary mounting groove 12 can match the cross-sectional shape of the protruding part 31.

[0046] For example, the cross-sectional shape of the protruding part 31 can be circular, and the cross-sectional shape of the auxiliary mounting groove 12 can also be circular. Also for example, the cross-sectional shape of the protruding part 31 can be rectangular, and the cross-sectional shape of the auxiliary mounting groove 12 can also be rectangular. Also for example, the cross-sectional shape of the protruding part 31 can be square, and the cross-sectional shape of the auxiliary mounting groove 12 can also be square. Thus, the auxiliary mounting groove 12 can just sleeve on the protruding part 31.

[0047] As described above, sleeving the auxiliary mounting groove 12 of the bracket body 1 on the protruding part 31 of the engine body 3 can assist the operator in temporarily supporting the bracket body 1. Thus, the operator can hold the bracket body 1 steadily with one hand and then fix and install the bracket body 1 and the engine body 3 with the other hand, so that the operation of installing the wire harness fixing bracket by a single person can be easily realized.

[0048] In one example, the number of the auxiliary mounting grooves 12 is at least two, at least two auxiliary mounting grooves 12 are spaced along the first direction, the axes of at least two auxiliary mounting grooves 12 are parallel to each other and perpendicular to the first direction, and the openings of at least two auxiliary mounting grooves 12 face the same direction.

[0049] For example, in Figure 1In the embodiment, the number of the auxiliary installation slots 12 can be two, but the number of the auxiliary installation slots 12 can also be three, four or five. Figure 1 The number of auxiliary installation slots 12 shown is two for example. The two auxiliary installation slots 12 are spaced apart along the first direction, the axes of the two auxiliary installation slots 12 are parallel to each other and perpendicular to the first direction, and the slot openings of the two auxiliary installation slots 12 face the same direction.

[0050] Continue to refer Figure 5 As shown, the protrusions 31 of the engine body 3 correspond to the auxiliary installation slots 12 one by one, and the auxiliary installation slots 12 are suitable for being sleeved on the corresponding protrusions 31 and cooperating with the corresponding protrusions 31. Figure 5 As shown, the number of the protrusions 31 of the engine body 3 and the number of the auxiliary installation slots 12 can both be two. However, the number of the protrusions 31 of the engine body 3 and the number of the auxiliary installation slots 12 can also both be three, four or five.

[0051] Thus, since at least two auxiliary mounting grooves 12 are spaced apart along the first direction and are respectively sleeved on the corresponding protrusions 31 through at least two auxiliary mounting grooves 12, the bracket body 1 can be temporarily hung on the engine body 3 through the cooperation between the auxiliary mounting grooves 12 and the protrusions 31, so that the operator can use both hands to fix the bracket body 1 and the engine body 3, thereby improving the installation efficiency of the wire harness fixing bracket.

[0052] In one example, at least two auxiliary mounting grooves 12 are located on the upper side of the main guide cavity. Thus, when at least two auxiliary mounting grooves 12 are respectively sleeved on the corresponding protrusions 31, the bracket body 1 can be more stably hung on the engine body 3 through the cooperation between the auxiliary mounting grooves 12 and the protrusions 31, which is helpful to avoid the shaking of the bracket body 1 that may occur when the fixing is not completed, and thus it is helpful to improve the efficiency of the operator to install the wiring harness fixing bracket.

[0053] In one example, the wiring harness fixing bracket further includes at least three fixing members 4, and the fixing members 4 are rod-shaped, for example, Figure 5 and Figure 6 In the embodiment, the number of the fixing members 4 may be three, but the number of the fixing members 4 may also be four, five or six, etc.

[0054] Accordingly, the support body 1 and the engine body 3 each have at least three mounting holes 13. Figure 1 In the embodiment, the bracket body 1 and the engine body 3 each have three mounting holes 13 , but the bracket body 1 and the engine body 3 may each have four mounting holes 13 , five mounting holes 13 , or six mounting holes 13 , etc.

[0055] Moreover, the mounting holes 13 of the bracket body 1 and the mounting holes 13 of the engine body 3 correspond to the fixing members 4 one by one. For example, referring to Figure 6 as shown, the number of the mounting holes 13 of the bracket body 1, the number of the mounting holes 13 of the engine body 3, and the number of the fixing members 4 can all be three, but can also all be four, five, six, etc.

[0056] Continuing to refer to Figure 1 as shown, the first direction is the direction of lateral extension, and at least two of the at least three mounting holes 13 of the bracket body 1 are located above the main guiding cavity 11 and are spaced apart along the first direction. At least one of the at least three mounting holes 13 of the bracket body 1 is located below the main guiding cavity 11.

[0057] For example, in Figure 5 , the bracket body 1 can have three mounting holes 13. It can be that two of the mounting holes 13 of the bracket body 1 are located above the main guiding cavity 11 and are spaced apart along the first direction, and one mounting hole 13 of the bracket body 1 is located below the main guiding cavity 11.

[0058] However, when the bracket body 1 has four mounting holes 13, it can be that two of the mounting holes 13 of the bracket body 1 are located above the main guiding cavity 11 and are spaced apart along the first direction, and two mounting holes 13 of the bracket body 1 are located below the main guiding cavity 11; it can also be that three of the mounting holes 13 of the bracket body 1 are located above the main guiding cavity 11 and are spaced apart along the first direction, and one mounting hole 13 of the bracket body 1 is located below the main guiding cavity 11.

[0059] Continuing to refer to Figure 6 as shown, at least three fixing members 4 respectively pass through the corresponding mounting holes 13 of the bracket body 1 and the corresponding mounting holes 13 of the engine body 3 in sequence, so that the bracket body 1 and the engine body 3 are detachably connected through the fixing members 4. In this embodiment, taking the number of the mounting holes 13 of the bracket body 1, the number of the mounting holes 13 of the engine body 3, and the number of the fixing members 4 all being three as shown in Figure 6 as an example.

[0060] Thus, the connection between the bracket body 1 and the engine body 3 can be realized through at least three fixing members 4. Moreover, since at least two fixing members 4 are located above the main guiding cavity 11 and are spaced apart along the first direction, during installation, the bracket body 1 can be pre-fixed by first installing the two fixing members 4 located above the main guiding cavity 11, which is convenient for the subsequent installation of the other fixing members 4. At the same time, since at least one fixing member 4 is located below the main guiding cavity 11 and cooperates with the at least two fixing members 4 located above the main guiding cavity 11, the connection between the bracket body 1 and the engine body 3 can have better stability.

[0061] In one example, the fixing member 4 can be a bolt. For example, the nut at the first end of the bolt abuts against the bracket body 1, and the second end of the bolt passes through the corresponding mounting hole 13 of the bracket body 1 and is screwed into the corresponding mounting hole 13 of the engine body 3. Among them, the mounting hole 13 of the engine body 3 is a bolt hole. Thus, the engine body 3 and the bracket body 1 are fixedly connected.

[0062] In another example, the fixing member 4 can also be a pin. For example, the first end of the pin has a pin cap, which abuts against the bracket body 1. The second end of the pin sequentially passes through the corresponding mounting hole 13 of the bracket body 1 and the corresponding mounting hole 13 of the engine body 3, and is riveted to the engine body 3. Thus, the engine body 3 and the bracket body 1 are fixedly connected.

[0063] In another example, the fixing member 4 can also be a screw. The first end of the screw has a screw cap, which abuts against the bracket body 1. The second end of the screw passes through the corresponding mounting hole 13 of the bracket body 1 and is screwed into the corresponding mounting hole 13 of the engine body 3. Among them, the mounting hole 13 of the engine body 3 is a screw hole. Thus, the engine body 3 and the bracket body 1 are fixedly connected.

[0064] In one example, referring to Figure 1 As shown, the number of the auxiliary mounting grooves 12 is at least two. At least two auxiliary mounting grooves 12 are spaced along the first direction. The axes of at least two auxiliary mounting grooves 12 are parallel to each other and perpendicular to the first direction. The openings of at least two auxiliary mounting grooves 12 face the same direction.

[0065] For example, in Figure 1 , the number of the auxiliary mounting grooves 12 can be two, but the number of the auxiliary mounting grooves 12 can also be three, four, five, etc. In this embodiment, taking the number of the auxiliary mounting grooves 12 shown in Figure 1 as two for example. Two auxiliary mounting grooves 12 are spaced along the first direction. The axes of two auxiliary mounting grooves 12 are parallel to each other and perpendicular to the first direction. The openings of two auxiliary mounting grooves 12 face the same direction.

[0066] Referring to Figure 5 As shown, the protrusions 31 of the engine body 3 correspond to the auxiliary mounting grooves 12 one by one, and the auxiliary mounting grooves 12 are adapted to be sleeved on the corresponding protrusions 31 and cooperate with the corresponding protrusions 31. For example Figure 5 As shown, the number of the protrusions 31 of the engine body 3 and the number of the auxiliary mounting grooves 12 can both be two. But the number of the protrusions 31 of the engine body 3 and the number of the auxiliary mounting grooves 12 can also both be three, four or five, etc.

[0067] Continuing to refer to Figure 1As shown, at least two of the at least three mounting holes 13 of the bracket body 1 correspond to the auxiliary mounting grooves 12 one by one, and the mounting holes 13 penetrate through the bottom of the corresponding auxiliary mounting grooves 12 along the axial direction of the auxiliary mounting grooves 12. For example, in Figure 1 it may be that two mounting holes 13 correspond to the auxiliary mounting grooves 12 one by one.

[0068] Thus, the mounting holes 13 penetrate through the bottom of the corresponding auxiliary mounting grooves 12, making the positions of the mounting holes 13 and the auxiliary mounting grooves 12 relatively compact, saving space, and further being beneficial to reducing the possibility of friction and collision of the wire harness.

[0069] In one example, referring to Figure 2 as shown, one of the mounting holes 13 is an oblong hole. Thus, since the oblong hole is used as one of the mounting holes 13 of the bracket body 1, even if there are certain mounting errors or machining errors in the bracket body 1, etc., the fixing member 4 can correctly pass through the corresponding mounting hole 13 of the bracket body 1 and extend into the corresponding mounting hole 13 of the engine body 3.

[0070] In one example, in order to reduce the weight of the bracket body 1, correspondingly, referring to Figure 1 and Figure 8 as shown, the cross-section of the bracket body 1 is C-shaped. One side of the open C-shaped bracket body 1 is adapted to enclose with the engine body 3 to form the main guiding cavity 11.

[0071] At the same time, since the C-shaped bracket body 1 has an opening, the internal wire harness 2 can be first installed inside the bracket body 1 from the opening, and then the bracket body 1 can be installed on the engine body 3. In this way, it is also beneficial to the quick and orderly installation of the internal wire harness 2 in the main guiding cavity 11.

[0072] In one example, the bracket body 1 has multiple pairs of first cable tie holes 14, and the multiple pairs of first cable tie holes 14 are spaced apart along the first direction. The first cable tie holes 14 penetrate and extend into the main guiding cavity 11, and the two first cable tie holes 14 of each pair of first cable tie holes 14 are respectively located on both sides of the internal wire harness 2 in the main guiding cavity 11. For example, in Figure 2 it, the bracket body 1 may have three pairs of first cable tie holes 14, but the bracket body 1 may also have two pairs of first cable tie holes 14, four pairs of first cable tie holes 14, or five pairs of first cable tie holes 14, etc.

[0073] Thus, by passing the cable tie through a pair of first cable tie holes 14 in sequence within the main guiding cavity 11, the internal wire harness 2 can be tied to the inner wall of the main guiding cavity 11 by the cable tie, and further it is beneficial to avoid the contact between the internal wire harness 2 and the engine body 3, so that the high temperature of the engine body 3 cannot directly damage the internal wire harness 2, and it is beneficial to improve the service life of the internal wire harness 2.

[0074] In one example, the bracket body 1 has at least three pairs of first cable tie holes 14, and at least one pair of first cable tie holes 14 is provided at the first end, the second end, and the middle part of the bracket body 1. For example, in Figure 2 the bracket body 1 may have three pairs of first cable tie holes 14, and one pair of first cable tie holes 14 is provided at the first end, the second end, and the middle part of the bracket body 1. However, the bracket body 1 may also have four pairs of first cable tie holes 14, five pairs of first cable tie holes 14, six pairs of first cable tie holes 14, etc.

[0075] Thus, by having at least three pairs of first cable tie holes 14, the internal wire harness 2 can be tied to the inner wall of the main guiding cavity 11 at the positions of the first end, the second end, and the middle part of the main guiding cavity 11, which is beneficial to avoiding the shaking of the internal wire harness 2 due to unstable tying in the main guiding cavity 11, resulting in the contact between the internal wire harness 2 and the engine body 3 and affecting the service life of the internal wire harness 2.

[0076] In one example, referring to Figures 5 to 8 as shown, the wire harness fixing bracket further includes a constraint member 5, and still referring to Figures 1 to 4 as shown, the bracket body 1 further has a branch guiding cavity 15.

[0077] Still referring to Figure 2 as shown, the first end of the branch guiding cavity 15 is communicated with the main guiding cavity 11, and the second end of the branch guiding cavity 15 penetrates through the bracket body 1.

[0078] Wherein, referring to Fig. 6, a part of the internal wire harness 2 extends from the branch guiding cavity 15 to the outside of the bracket body 1 to become an external wire harness 21.

[0079] Moreover, there is a mutually matching mounting structure 6 between the constraint member 5 and the bracket body 1. The constraint member 5 and the bracket body 1 are detachably connected through the mounting structure 6, and the constraint member 5 is suitable for constraining the external wire harness 21. For example, the constraint member 5 has a through hole, and the external wire harness 21 can just pass through the through hole, and the through hole can be in interference fit with the external wire harness 21. Thus, the constraint member 5 can form a constraint on the external wire harness 21.

[0080] As described above, the branch guiding cavity 15 can guide a part of the internal wire harness 2 to the outside of the bracket body 1 to become an external wire harness 21 for connection with other components. At the same time, the external wire harness 21 can also be constrained by the constraint member 5, which is beneficial to avoiding problems such as collision and abrasion of the external wire harness 21, and thus can improve the service life of the external wire harness 21.

[0081] In one example, referring to Figure 3 and Figure 5As shown, the mounting structure 6 of the bracket body 1 can be a slot, and the mounting structure 6 of the restraint member 5 can be a plug. The restraint member 5 and the bracket body 1 can be detachably fixedly connected through the cooperation of the slot and the plug.

[0082] In one example, referring to Figure 9 and Figure 10 as shown, the restraint member 5 can be a fir-tree shaped cable tie, and the pin of the fir-tree shaped cable tie is the mounting structure 6 of the restraint member 5. Referring to Figure 2 and Figure 4 as shown, the mounting structure 6 of the bracket body 1 can be an oval hole, and the pin of the fir-tree shaped cable tie can be inserted into the oval hole. Thus, the restraint member 5 and the bracket body 1 can be detachably fixedly connected through the cooperation of the pin and the oval hole.

[0083] In one example, the bracket body 1 can have two second cable tie holes 16, the second cable tie holes 16 penetrate and extend into the branch guiding cavity 15, and the two second cable tie holes 16 are respectively located on both sides of the internal wire harness 2 in the branch guiding cavity 16.

[0084] Thus, passing the cable tie through the two second cable tie holes 16 in sequence in the branch guiding cavity 16 can bind the internal wire harness 2 to the inner wall of the branch guiding cavity 16 through the cable tie, which is beneficial to avoiding the contact between the internal wire harness 2 and the engine body 3, so that the high temperature of the engine body 3 cannot directly damage the internal wire harness 2, and is beneficial to improving the service life of the internal wire harness 2.

[0085] In one example, the material of the bracket body 1 can be plastic. Thus, it can be better manufactured into the required shape of the bracket body 1 to meet the requirements of complex and twisted spatial layout, and at the same time, it also has a lighter weight.

[0086] In one example, referring to Figure 3 as shown, the bracket body 1 also has a strengthening structure 17. For example, the strengthening structure 16 can be a plurality of reinforcing ribs distributed at intervals along the length direction of the bracket body 1. Thus, it is beneficial to improve the strength of the bracket body 1, which can provide better protection for the internal wire harness 2 in the main guiding cavity 2 and the branch guiding cavity 15, and can also provide more stable support for the restraint member 5, and further is beneficial to better protecting the external wire harness 21.

[0087] In the embodiment of the present disclosure, sleeving the auxiliary mounting groove 12 of the bracket body 1 on the protruding part 31 of the engine body 3 can assist the operator in temporarily supporting the bracket body 1. Thus, the operator can hold the bracket body 1 steadily with one hand and then fix and install the bracket body 1 and the engine body 3 with the other hand, so that the operation of single-person installing the wire harness fixing bracket can be easily realized.

[0088] This embodiment also provides an engine, which includes an internal wire harness 2, an engine body 3, and a wire harness fixing bracket according to any one of the first aspects. The internal wire harness 2 is installed in the main guiding cavity 11 of the wire harness fixing bracket. The engine body 3 has a protruding portion 31, and the protruding portion 31 can extend into the auxiliary installation groove 12 of the wire harness fixing bracket and cooperate with the auxiliary installation groove 12.

[0089] In the embodiment of the present disclosure, by sleeving the auxiliary installation groove 12 of the bracket body 1 on the protruding portion 31 of the engine body 3, it is possible to assist the operator in temporarily supporting the bracket body 1. Thus, the operator can steady the bracket body 1 with one hand and then fix and install the bracket body 1 and the engine body 3 with the other hand, so that it is easy to realize the operation of installing the wire harness fixing bracket by a single person.

[0090] This embodiment also provides a vehicle, which includes the engine according to the second aspect.

[0091] In the embodiment of the present disclosure, by sleeving the auxiliary installation groove 12 of the bracket body 1 on the protruding portion 31 of the engine body 3, it is possible to assist the operator in temporarily supporting the bracket body 1.
