Technical Field
[0001] The present application relates to the technical field of vehicles, and in particular to a vehicle wiring harness waterproofing mechanism and a vehicle thereof. Background Art
[0002] Wiring harnesses are commonly used components in vehicles, and are used to connect various electrical components. When the vehicle wiring harness enters the dry area inside the cabin from the wet area outside the cabin, a "low water ring" is usually required to block the water in the wet area outside the cabin from entering the dry area inside the cabin along the wiring harness based on the physical property that water flows to lower places, thus achieving a physical waterproof effect.
[0003] The waterproof structure in the related art realizes the "low water ring" design of the wiring harness by using a rubber plug and filling it with waterproof cement. However, this method is complicated in process and requires a specially assembled mold for construction, which is not only costly but also has low production efficiency. Utility Model Content
[0004] Based on this, it is necessary to provide a vehicle wiring harness waterproof mechanism and a vehicle thereof with a simple structure and low cost.
[0005] In order to solve the above technical problems, this application provides the following technical solutions:
[0006] A vehicle wiring harness waterproof mechanism, the vehicle wiring harness waterproof mechanism comprising: a sleeve, used for sealing and sleeved on the wiring harness; a bracket, connected to the sleeve, used for guiding and positioning the wiring harness;

[0008] In one embodiment, along the vertical direction of the vehicle, the position of the connection between the second support rod and the first support rod is not higher than that of the first support rod.
[0009] In one embodiment, the angle between the second support rod and the first support rod is set to θ, 30 degrees ≤ θ ≤ 150 degrees.

[0011] In one embodiment, the sleeve body includes a sleeve and a retaining ring, the sleeve is used to be sealingly mounted on the wiring harness, the retaining ring is arranged on the outer circumferential wall of the sleeve and protrudes from the outer circumferential wall of the sleeve along the radial direction of the sleeve; and the retaining ring is arranged around the circumference of the sleeve for at least one circle.
[0012] In one of the embodiments, at least one circle of protrusions is provided on the inner circumferential wall of the sleeve, and the protrusions protrude from the inner circumferential wall of the sleeve along the radial direction of the sleeve.
[0013] In one embodiment, the first support rod and the sleeve are detachably connected.
[0014] In one of the embodiments, the vehicle wiring harness waterproofing mechanism further includes a binding strap, and the first support rod is in contact with the sleeve and is wound and bound together by the binding strap.
[0015] In one embodiment, a mounting groove is provided on the outer peripheral wall of the sleeve, and the binding strap wound around the sleeve is located in the mounting groove.
[0016] It can be understood that through the setting of the mounting groove, the mounting groove can be used to limit the strap to prevent the strap from slipping off the sleeve, thereby improving the reliability of the connection between the two; at the same time, in the process of wrapping the strap, the mounting groove can position and limit the strap, so that the strap can quickly and accurately bind and fix the sleeve and the first support rod together.

After the wiring harness is guided by the second support rod, the wiring harness on the second support rod will extend below the first support rod, thereby forming a "low water ring" arrangement between the wiring harness on the first support rod, thereby achieving physical waterproofing. This structure does not require the use of waterproof cement, nor does it require additional auxiliary tools for auxiliary installation. It is not only simple but also low-cost.

The term "and / or" used in the specification of this application includes any and all combinations of one or more related listed items.
[0031] like Figure 1 As shown, the present application provides a vehicle wiring harness waterproofing mechanism 100, which is installed on a vehicle wiring harness 200 and is used to block a wet area outside the vehicle cabin from a dry area inside the vehicle cabin, thereby preventing water in the wet area outside the vehicle cabin from entering the dry area inside the vehicle cabin along the wiring harness 200.
[0032] For details, please continue to refer to Figure 1 The vehicle wiring harness waterproof mechanism 100 includes a sleeve 10 and a bracket 20. The sleeve 10 is used for sealing and is arranged on the wiring harness 200. The bracket 20 is connected to the sleeve 10 and is used for guiding and positioning the wiring harness 200. That is, the layout and trend of the wiring harness 200 will be guided by the bracket 20.
[0033] Furthermore, if Figure 2As shown, the bracket 20 includes a first support rod 21 and a second support rod 22. The first support rod 21 is connected to the sleeve 10, and the second support rod 22 is connected to one end of the first support rod 21 away from the sleeve 10, and is arranged at a preset angle with the first support rod 21, and along the vertical direction z of the vehicle, the second support rod 22 is relatively located below the first support rod 21. In this way, the first support rod 21 and the second support rod 22 are used to guide the wire harness 200, so that the wire harness 200 is arranged along a preset path, and in the vertical direction z of the vehicle, the second support rod 22 is located below the first support rod 21. When the wire harness 200 is guided by the second support rod 22, the wire harness 200 on the second support rod 22 will extend to the bottom of the first support rod 21, thereby forming a "low water ring" arrangement with the wire harness 200 on the first support rod 21, so as to achieve physical waterproofing. This structure does not require the use of waterproof cement, nor does it require additional auxiliary tools for auxiliary installation. It is not only simple but also low in cost.
[0034] Please continue to refer to Figure 2 The sleeve body 10 can be configured as a silicone sleeve or a rubber sleeve. In this embodiment, the sleeve body 10 is configured as a rubber sleeve.
[0035] Furthermore, the sleeve 10 can be integrally formed by injection molding, which is not only convenient to process and has low production cost, but also can avoid the joint seams that appear after connecting multiple parts, thereby reducing the overall barrier and waterproof effects of the sleeve 10.
[0036] For example, Figure 2 and Figure 3 As shown, the sleeve 10 includes a sleeve 11 and a retaining ring 12. The sleeve 11 is used to be sealingly sleeved on the wiring harness 200. The retaining ring 12 is arranged on the outer peripheral wall of the sleeve 11 and protrudes radially from the outer peripheral wall of the sleeve 11. The retaining ring 12 is arranged around the circumference of the sleeve 11 for at least one circle, so that the wet area outside the cabin is isolated from the dry area inside the cabin by the retaining ring 12 to improve the waterproof effect.
[0037] As preferably, Figure 3 As shown, at least one circle of raised portions 111 is provided on the inner circumferential wall of the sleeve 11, and the raised portions 111 protrude from the inner circumferential wall of the sleeve 11 along the radial direction of the sleeve 11. When the wire harness 200 passes through the sleeve 11, under the extrusion of the wire harness 200, the raised portions 111 will tightly abut and seal against the outer surface of the wire harness 200, thereby improving the sealing effect of the sleeve 11 on the wire harness 200, that is, improving the waterproof performance of the sleeve 11.
[0038] In one embodiment, the number of the protrusions 111 can be set to be multiple, and the multiple protrusions 111 are arranged on the inner peripheral wall of the sleeve 11 at intervals along the axial direction of the sleeve 11. In this way, in the axial direction of the sleeve 11, multiple abutment seals are formed between the multiple protrusions 111 and the wiring harness 200, thereby achieving multiple sealing effects, so as to further improve the waterproof performance of the sleeve 11.
[0039] Optionally, the number of the protrusions 111 can be set to two, three or four, etc. Of course, the specific number of the protrusions 111 can be set according to actual needs, which will not be described in detail here.
[0040] like Figure 3 As shown, the first support rod 21 is detachably connected to the sleeve 11. This facilitates the disassembly and installation of the entire support 20 and the sleeve body 10, and thus facilitates the replacement and maintenance of the support 20.
[0041] Exemplarily, the first support rod 21 and the sleeve 11 can be detachably connected by means of a snap connection, a strap wrapping connection, or the like.
[0042] In this embodiment, the first support rod 21 and the sleeve 11 are connected by winding a binding belt.
[0043] Specifically, please refer to Figure 3 The vehicle harness waterproof mechanism 100 further includes a binding belt 30, and the first support rod 21 is close to the sleeve 11 and is wound and tied by the binding belt 30. Here, the binding method of the binding belt 30 is not only convenient to operate, but also simple and reliable to connect.
[0044] For further information, please refer to Figure 3 The outer wall of the sleeve 11 is provided with a mounting groove 112, and the strap wound on the sleeve 11 is located in the mounting groove 112. In this way, the mounting groove 112 is used to limit the strap 30, so as to prevent the strap 30 from slipping off the sleeve 11, thereby improving the reliability of the connection between the two; at the same time, during the process of winding the strap 30, the mounting groove 112 can position and limit the strap 30, so that the strap 30 can quickly and accurately bind and fix the sleeve 11 and the first support rod 21 together.
[0045] Preferably, a convex ring 113 protruding along the radial direction of the sleeve 11 is provided on the outer peripheral wall of the sleeve 11 , and the convex ring 113 , the outer peripheral wall of the sleeve 11 , and the retaining ring 12 together form a mounting groove 112 .
[0046] like Figure 1 and Figure 2As shown, along the vertical direction z of the vehicle, the position of the connection between the second support rod 22 and the first support rod 21 is not higher than the first support rod 21. That is, in the vertical direction z of the vehicle, the second support rod 22 is always located below the first support rod 21. In this way, compared with the wire harness 200 on the first support rod 21, the wire harness 200 on the second support rod 22 is always at a low position, thereby forming a "low water ring" layout at the wire harness 200 at the second support rod 22.
[0047] Here, the connection mode between the second support rod 22 and the wire harness 200 can be set as a buckle connection or a binding tape winding connection. If the buckle connection is adopted, a corresponding buckle part can be provided on the second support rod 22, and the wire harness 200 is clamped on the buckle part. If the binding tape method is adopted, it can be wound by the binding tape.
[0048] In this embodiment, the connection method between the second support rod 22 and the wire harness 200 is the same as the connection method between the first support rod 21 and the sleeve 11, and both are connected and fixed by wrapping with a strap 30. In this way, during the overall installation of the bracket 20, the same method is used for connection and fixing, which is more convenient to operate and does not require changing the fixing method, which is conducive to improving the efficiency.
[0049] In one embodiment, the angle between the second support rod 22 and the first support rod 21 is set to θ, 30 degrees ≤ θ ≤ 150 degrees. It should be noted that the value of θ cannot be too small. If it is too small, the second support rod 22 will be closer to the first support rod 21, and the drainage effect is not good; if the value of θ is too large, the second support rod 22 and the first support rod 21 will tend to be on the same straight line, so that the "low water ring" layout cannot be formed. Therefore, in this application, the weight range of θ is [30 degrees, 150 degrees], which not only has a good drainage effect, but also can form a better "low water ring" layout.
[0050] Exemplarily, the value of θ is set to 30 degrees, 40 degrees, 50 degrees, 60 degrees, 70 degrees, 80 degrees, 90 degrees, 100 degrees, 110 degrees, 120 degrees, 130 degrees, 140 degrees and 150 degrees. Of course, the value of θ is not limited thereto, and it can be selected and set according to actual conditions.
[0051] Furthermore, the value range of θ is configured as: 60 degrees ≤ θ ≤ 120 degrees.
[0052] In this embodiment, the first support rod 21 is arranged horizontally, and the second support rod 22 is arranged in the vertical direction z, that is, the first support rod 21 and the second support rod 22 are arranged perpendicularly, that is, the value of θ is 90 degrees.
[0053] In one embodiment, the first support rod 21 and the second support rod 22 are configured as an integrated structure, which not only facilitates the processing of the entire support 20, but also effectively ensures the structural strength of the entire support 20.
[0054] Exemplarily, the bracket 20 is configured as a plastic bracket, and the first support rod 21 and the second support rod 22 can be formed by integral injection molding. Alternatively, the bracket 20 is configured as a metal bracket, such as a stainless steel bracket, an aluminum alloy bracket, etc. In this case, the first support rod 21 and the second support rod 22 can be formed by integral casting. Of course, the bracket 20 can also be formed by bending a stainless steel plate or an aluminum alloy plate.
[0055] In this embodiment, the bracket 20 is configured as a plastic bracket. For example, the bracket 20 is configured as a PVC plastic bracket, an ABS plastic bracket, etc.
[0056] The present application also provides a vehicle, comprising the vehicle wiring harness waterproofing mechanism 100 in any one of the above embodiments.
[0057] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0058] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
