Description

Technical Field

[0001] This utility model relates to the field of vehicle engineering technology, and in particular to a wiring harness fixing device and a vehicle. Background Technology

[0002] In automotive wiring harness layout design, the ends of the wiring harness need to be connected to the plugs of moving parts via plugs. Because the movement of these moving parts during use can cause instability at the plug-in points, cable ties are typically used in conjunction with process holes or through-holes on the moving parts to add a fixing point to the wiring harness, reducing its swaying or shifting. However, the fixing effect of cable ties is limited; the wiring harness will still sway or shift to varying degrees during use. Furthermore, the cable tie binding point is usually far from the plug-in point, meaning the fixing point of the wiring harness is far from the plug-in point, and the plug still risks detaching under stress.

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0031] like Figures 1-5 As shown, this utility model provides a wire harness fixing device, which is applied to a moving part and used to fix a wire harness 300. A first plug 100 is provided on the moving part, and a second plug 200 is connected to one end of the wire harness 300. The second plug 200 is plugged into the first plug 100 on the moving part. The wire harness fixing device includes a bracket 1, a sheath 2, and cable ties 3. The bracket 1 includes a fixing plate 11, a connecting plate 12, and a support member 14. The fixing plate 11 is fixedly connected to the moving part by means of fasteners such as bolts, screws, or rivets. The support member 14 is connected to the fixing plate 11 through the connecting plate 12. The fixing plate 11, the connecting plate 12, and the support member 14 are integrally formed or welded together. The support member 14 is spaced apart from the moving part, and the relative positional relationship between the support member 14 and the moving part can be changed by altering the structure of the connecting plate 12. The support member 14 has a receiving space, within which a sheath 2 is installed. The sheath 2 has a wire-passing hole 211, through which the wire harness 300 passes and fits against the wall of the wire-passing hole 211. Cable ties 3 are installed on the outside of the sheath 2 and the support member 14, and are used to secure the sheath 2 within the receiving space of the support member 14. By setting a bracket 1 and fixing it to the moving part, the sheath 2 is set on the bracket 1 and placed over the wire harness 300. The sheath 2 and the bracket 1 are secured by the cable ties 3, ensuring the effective fixation of the wire harness 300. Furthermore, the distance between the fixing point and the plug point of the wire harness 300 can be changed by adjusting the structure of the bracket 1, preventing the plug from coming loose under force during use.

[0032] Specifically, please refer to Figures 2-3As shown, the support member 14 has a U-shaped structure, including a base plate 141 and a first side plate 142 and a second side plate 143 located on both sides of the base plate 141. The base plate 141, the first side plate 142, and the second side plate 143 together form a U-shaped receiving space, the extending direction of which is the arrangement direction of the wire harness 300, i.e., the length direction of the wire harness 300. Both the first side plate 142 and the second side plate 143 are provided with through holes 144, and the two through holes 144 are at the same height on the first side plate 142 and the second side plate 143, respectively. The lower end of the sheath 2 is fitted against the base plate 141, and the upper end of the sheath 2 is higher than the height of the through hole 144. The cable tie 3 passes through the through hole 144 of the first side plate 142, wraps around the outer periphery of the support member 14, and then passes through the through hole 144 of the second side plate 143 to secure the sheath 2 within the receiving space. Since the upper end of the sheath 2 is higher than the height of the through hole 144, it can ensure that the cable tie 3 keeps the sheath 2 close to the base plate 141 after binding, thereby preventing the sheath 2 from shaking or shifting, and thus preventing the wire harness 300 from shaking or shifting.

[0033] Alternatively, please continue to refer to Figures 2-3 The height of one of the first side plate 142 and the second side plate 143 is greater than the height of the other, and a mounting hole 145 is provided on the higher of the first side plate 142 and the second side plate 143. Specifically, in this embodiment, the height of the second side plate 143 is greater than the height of the first side plate 142, the mounting hole 145 is provided on the second side plate 143, and the height of the mounting hole 145 is higher than the upper end of the sheath 2 to prevent the sheath 2 from obstructing the mounting hole 145. The mounting hole 145 is used to provide mounting points for sub-wires or control wires around the wiring harness 300, thereby facilitating vehicle wiring and reducing the number of parts.

[0034] Further, please refer to Figures 1-3As shown, the connecting plate 12 is angled to the fixing plate 11, and the connecting plate 12 is connected to the base plate 141 and angled to it. By angled to the fixing plate 11, the rigidity at the connection point is increased, preventing deformation that could cause displacement of the wire harness 300. Similarly, angled to the base plate 141, the rigidity at the connection point is also increased, preventing deformation that could cause displacement of the wire harness 300. In this embodiment, the connecting plate 12 is angled to the fixing plate 11, and the connecting plate 12 is angled to the base plate 141. The height of the sheath 2 can be changed by adjusting the angles of the connecting plate 12 to the fixing plate 11 and the base plate 141, respectively, ultimately ensuring that the second plug 200 of the wire harness 300 and the first plug 100 of the moving part are at the same height, preventing the wire harness 300 from twisting or deforming, or the plug from being subjected to stress. At the same time, the length of the connecting plate 12 can be changed simultaneously to change the position of the sheath 2 and the distance between the second plug 200, so that the distance between the fixing point and the plug point of the wire harness 300 is appropriate, and the plug is further protected from stress.

[0035] Optionally, the base plate 141 extends toward the fixed plate 11 to form an extension plate 13, and the connecting plate 12 is connected to the base plate 141 through the extension plate 13, that is, the connecting plate 12 and the extension plate 13 are set at an obtuse angle. By setting the extension plate 13, the distance between the base plate 141 and the connecting plate 12 is increased, making it more convenient to adjust the angle between the connecting plate 12 and the extension plate 13.

[0036] Alternatively, please refer to Figures 1-3 The bracket 1 also includes a reinforcing plate 15, the two ends of which are fixedly connected to the fixing plate 11 and the connecting plate 12 respectively, to enhance the rigidity and structural strength between the fixing plate 11 and the connecting plate 12. Two reinforcing plates 15 are provided, and the two reinforcing plates 15 are distributed at intervals along the length direction of the fixing plate 11. The reinforcing plate 15, the fixing plate 11 and the connecting plate 12 are integrally formed or welded together.

[0037] For further details, please refer to Figure 1 , Figure 4 and Figure 5As shown, the sheath 2 includes a body 21 and two limiting portions 22. A wire-passing hole 211 is provided on the body 21 and extends through the body 21. The two limiting portions 22 are located at both ends of the body 21 along the length direction of the wire harness 300, and the limiting portions 22 protrude from the outer edge of the body 21, and the two limiting portions 22 are attached to both ends of the support member 14 along the length direction of the wire harness 300. During assembly, the wire harness 300 is first passed through the wire-passing hole 211 of the body 21, and then the U-shaped support member 14 is placed with its opening facing upwards, and the body 21 is pressed into the receiving space of the support member 14 from above, while the limiting portions 22 are attached to both ends of the support member 14 along the length direction of the wire harness 300. After assembly, the sheath 2 is able to restrict sliding along the length direction of the wire harness 300.

[0038] Specifically, two wire-passing holes 211 are provided, arranged side by side on the body 21, thereby accommodating more wire harnesses 300, saving layout space and reducing the number of components. The inner diameter of the wire-passing hole 211 is set to be smaller than the outer diameter of the wire harness 300, and the body 21 is capable of elastic deformation. With this configuration, after the wire harness 300 is inserted into the wire-passing hole 211, the hole wall of the wire-passing hole 211 undergoes elastic deformation and fits tightly against the wire harness 300, thereby preventing the wire harness 300 from rolling or shifting.

[0039] Optionally, the main body 21 also has a deformable opening 212, which penetrates the main body 21 and the limiting part 22 and communicates with the wire passage hole 211. The width of the deformable opening 212 is smaller than the diameter of the wire passage hole 211. When assembling the wire harness 300, the deformable opening 212 is pried open by external force, allowing the wire harness 300 to enter the wire passage hole 211 through the deformable opening 212. After the external force is removed, the deformable opening 212 returns to its original shape under the action of elastic force, and the wall of the wire passage hole 211 is tightly attached to the wire harness 300. Since the width of the deformable opening 212 is smaller than the diameter of the wire passage hole 211, the wire passage hole 211 is also prevented from falling off from the wire passage opening after assembly. By setting the deformable opening 212, the wire passage hole 211 does not need to be inserted from one end of the wire harness 300, reducing the workload and lowering the assembly difficulty.

[0040] This utility model provides a vehicle, including the wiring harness fixing device in this embodiment. By setting the wiring harness fixing device in this embodiment, the wiring harness 300 of the vehicle is arranged more smoothly and the plug connection is more reliable.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
