Detailed implementation manners
[0025] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to specific embodiments and the accompanying drawings.
[0026] It should be noted that unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present utility model should have the ordinary meanings understood by those of ordinary skill in the art to which this application belongs.

The terms such as "upper", "lower", "left" and "right" are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.
[0027] Existing vehicles are equipped with various wire harnesses. Due to the large volume of the vehicle, through-hole sealing arrangements of the wire harnesses are involved to prevent external water or debris from passing through the wire harness holes and affecting the internal wire harnesses or other electrical equipment.
[0028] When the battery is arranged in the rear trunk, it is necessary to supply power to the engine compartment fuse box in front of the vehicle through a power cord. The wire harness usually uses large-square wires of 25-35 square. Due to the need for wiring to pass through the floor through-hole, it is necessary to seal the through-hole on the floor. Since the diameter of the wire harness is large, the ordinary snap-on rubber sleeve is affected by the stress of the wire harness and there is a situation of detaching from the through-hole, resulting in poor through-hole sealing.
[0029] Based on this, the present application provides a via hole sealing structure, which can be stably connected to the plate body where the via hole is located, avoiding the situation that the sealing structure is separated from the plate body or the via hole due to excessive wire harness stress, and greatly improving the sealing performance of the sealing structure.
[0030] Hereinafter, one or more specific embodiments of the present application will be described in detail with reference to the accompanying drawings.
[0031] The present application provides a via hole sealing structure, as Figure 1 shown, a via hole 31 is provided on a plate body 30, and the sealing structure includes:
[0032] As Figure 2 shown, a sealing sleeve 10, which is used to cover the via hole 31, includes a wire harness channel 11 for communicating with the via hole 31, and a sealing connection portion 12 is provided at an opening of the wire harness channel 11 close to the via hole 31;
[0033] As Figure 3 and Figure 4 shown, a protective shell 20 is sleeved on the periphery of the sealing sleeve 10, and includes a protective connection portion 21 located on a side of the sealing connection portion 12 away from the plate body 30, and the protective connection portion 21 and the sealing connection portion 12 are connected to the plate body 30 through a fixing member 32.
[0034] Specifically, the material of the sealing sleeve 10 can be a flexible material such as rubber, and the material of the protective shell 20 can be a rigid material such as plastic. The sealing sleeve 10 is located between the protective shell 20 and the plate body 30, and is in interference fit with the protective shell 20 and the plate body 30 under the extrusion force of the fixing member 32, so that the sealing effect of the sealing structure on the via hole 31 is greatly improved.
[0035] The wire harness channel 11 allows the wire harness passing through the via hole 31 to pass through. The setting of the wire harness channel 11 enables the sealing structure to not only seal the via hole 31, but also allow the wire harness to pass through the via hole 31.
[0036] Specifically, the fixing member 32 can be a bolt, and the bolt sequentially passes through the protective connection portion 21, the sealing connection portion 12 and the plate body 30 to fixedly connect the protective connection portion 21, the sealing connection portion 12 and the plate body 30, so that the protective shell 20, the sealing sleeve 10 and the plate body 30 are fixedly connected, which is beneficial to the sealing structure stably covering the via hole 31 and stably sealing the via hole 31, thereby improving the sealing effect of the sealing structure.
[0037] In this embodiment, by providing a sealing sleeve 10 and a protective shell 20 which are sleeved and connected, the through-hole 31 is sealed and covered. The protective shell 20 is located outside the sealing sleeve 10 to protect the sealing sleeve 10, preventing the sealing sleeve 10 from directly contacting the outside world, which may affect the sealing performance of the sealing sleeve 10 and further affect the sealing performance of the sealing structure. This is beneficial to improving the sealing performance of the sealing structure. The sealing connection part 12 of the sealing sleeve 10 and the protective connection part 21 of the protective shell 20 are connected to the plate body 30 through a fixing member 32, so that the sealing structure is stably connected to the plate body 30, and further avoiding the situation that the sealing structure detaches from the through-hole 31 under the action of the wire harness stress, which is beneficial to improving the sealing performance of the sealing structure.
[0038] In some embodiments, as Figure 2 and Figure 5 shown, a wire harness installation tube 13 communicating with the wire harness channel 11 is provided at the opening of the wire harness channel 11 far from the through-hole 31; the protective shell 20 includes a protective channel 22 for accommodating the wire harness channel 11. A wire harness installation cover 23 is provided at the opening of the protective channel 22 far from the through-hole 31. The wire harness installation cover 23 is arranged adjacent to the wire harness installation tube 13 and is located outside the wire harness installation tube 13.
[0039] Specifically, the wire harness installation tube 13 has an interference fit with the wire harness. When the wire harness passes through the wire harness channel 11, a certain binding force is applied to the wire harness, which closely fits with the wire harness, thereby preventing foreign matters from entering the through-hole 31 through the opening of the wire harness channel 11 far from the through-hole 31. In addition, the setting of the wire harness installation tube 13 also increases the length of the wire harness channel 11. Even if foreign matters enter the wire harness channel 11 through the wire harness installation tube 13, the wire harness installation tube 13 can play a certain buffering role to prevent foreign matters from directly entering the through-hole 31, which is beneficial to improving the sealing performance of the sealing structure.
[0040] Specifically, the protective shell 20 is sleeved outside the sealing sleeve 10. The protective shell 20 is provided with a protective channel 22, which can not only accommodate the sealing sleeve 10 and thus accommodate the wire harness channel 11, but also allow the wire harness passing through the wire harness channel 11 to pass through. A protective connection part 21 is provided at the opening of the protective channel 22 close to the through-hole 31, and this opening allows the sealing sleeve 10 to pass through. A wire harness installation cover 23 is provided at the opening of the protective channel 22 far from the through-hole 31. The wire harness installation cover 23 protrudes relative to the protective shell 20 and is arranged adjacent to the wire harness installation tube 13. That is, the wire harness installation tube 13 is located inside the protective shell 20, and the wire harness installation cover 23 is located outside the protective shell 20. The wire harness installation cover 23 covers and protects the end of the wire harness installation tube 13, preventing foreign matters from directly contacting the wire harness installation tube 13 and damaging the wire harness installation tube 13, which is beneficial to extending the service life of the wire harness installation tube 13 and further beneficial to extending the service life of the sealing structure.
[0041] It should be noted that the wire harness installation cover 23 is arranged around the opening of the protection channel 22. One side of the opening has a plate body 30, and the wire harness installation cover 23 is arranged around the other sides of the opening, and together with the plate body 30, it surrounds the periphery of the opening to protect the wire harness installation pipe 13 by surrounding it.
[0042] In some embodiments, as Figure 3 shown, the bottom surface of the protection channel 22 is an inclined surface, and a drain hole 24 is provided between the inclined surface and the wire harness installation cover 23.
[0043] Specifically, when the plate body 30 is a vertical structure, the bottom surface of the protection channel 22 is the surface intersecting with the plate body 30; when the plate body 30 is a horizontal structure, the bottom surface of the protection channel 22 is the surface opposite to the plate body 30.
[0044] Specifically, the side of the inclined surface close to the wire harness installation cover 23 is the lower part of the inclined surface, and the drain hole 24 is arranged at the lower part of the inclined surface, which is convenient for draining the water in the protection channel 22, thereby avoiding the water in the protection channel 22 from entering the sealing sleeve 10 and then entering the through hole 31, which is beneficial to the sealing performance of the sealing structure.
[0045] It should be noted that the drain hole 24 can be a square hole, which can not only play the role of draining water, but also play the role of reducing the weight and cost of the protection shell 20, which is beneficial to reducing the cost of the sealing structure.
[0046] In some embodiments, as Figure 2 shown, a baffle 14 extends outward from the bottom surface of the wire harness channel 11, and the baffle 14 is used to at least partially cover the drain hole 24.
[0047] Specifically, the bottom surface of the wire harness channel 11 is arranged opposite to the bottom surface of the protection channel 22, and the drain hole 24 is provided on the bottom surface of the protection channel 22. While meeting the drainage requirement, it enables foreign objects in the outside world to contact the sealing sleeve 10 through the drain hole 24, which has the problem of damaging the sealing sleeve 10 and increasing the chance of foreign objects in the outside world entering the wire harness channel 11. Therefore, in order to avoid the problems brought by the drain hole 24, a baffle 14 extending outward is provided on the bottom surface of the wire harness channel 11 (that is, the baffle 14 is located outside the sealing sleeve 10 and at the bottom surface of the sealing sleeve 10) so that the baffle 14 shields the drain hole 24 to prevent foreign objects in the outside world from directly contacting the sealing sleeve 10.
[0048] Exemplarily, the baffle 14 can prevent the ground stones from hitting the sealing sleeve 10 during driving, resulting in damage to the sealing sleeve 10 and affecting the sealing performance.
[0049] It should be noted that the shielding area of the baffle 14 is set larger than the area of the drain hole 24 to ensure the shielding effect of the baffle 14.
[0050] In some embodiments, asFigure 3 As shown, there are cable tie mounting holes 231 provided on the wire harness mounting cover 23.
[0051] Specifically, the cable tie mounting holes 231 are used to mount cable ties, and the cable ties are used to bundle the wire harness on the wire harness mounting cover 23 to resist part of the stress of the wire harness, ensuring the stability of the wire harness relative to the sealing structure, and thus being beneficial to the stability and sealing performance of the sealing structure.
[0052] It should be noted that there are multiple cable tie mounting holes 231 provided on the wire harness mounting cover 23, and the distance between two adjacent cable tie mounting holes 231 is the same to meet the bundling requirements of different wire harness sizes.
[0053] In some embodiments, as Figure 2 and Figure 3 shown, on one side of the sealing connection part 12 close to the protection connection part 21, there is a buckle 121, and on the protection connection part 21, there is a card slot 211 adapted to the buckle 121. The sealing connection part 12 and the protection connection part 21 are snap-connected through the buckle 121 and the card slot 211.
[0054] Specifically, the sealing connection part 12 and the protection connection part 21 are snap-connected through the buckle 121 and the card slot 211, making the connection between the protection shell 20 and the sealing sleeve 10 more sealed and stable, which is beneficial to improving the sealing performance of the sealing structure.
[0055] In addition, the buckle 121 protrudes relative to the card slot 211. Setting the buckle 121 on the sealing connection part 12 can prevent the buckle 121 from affecting the connection between the sealing connection part 12 and the plate body 30, and thus is beneficial to the sealed connection between the sealing structure and the plate body 30.
[0056] In some embodiments, as Figure 2 shown, on one side of the sealing connection part 12 close to the plate body 30, there is a waterproof raised rib 15, and the waterproof raised rib 15 is arranged around the opening of the wire harness channel 11.
[0057] Specifically, the waterproof raised rib 15 is located outside the opening of the wire harness channel 11 and is arranged around the opening, which can comprehensively block water from entering the opening of the wire harness channel 11 and then into the through hole 31, being beneficial to improving the sealing performance of the sealing structure.
[0058] In this embodiment, the setting of the waterproof raised rib 15 can further enhance the sealed connection between the sealing sleeve 10 and the plate body 30 and improve the sealing and waterproof performance of the sealing structure.
[0059] It should be noted that there are multiple waterproof raised ribs 15, which are sequentially arranged around the opening of the wire harness channel 11 to achieve multi-layer waterproofing of the opening and further improve the sealing and waterproof performance of the sealing structure.
[0060] In some embodiments, asFigure 2 As shown, a snap ring 16 is provided at the opening of the wire harness channel 11 close to the via hole 31, and the snap ring 16 is used for snap connection with the via hole 31.
[0061] Specifically, the sealing sleeve 10 covers the via hole 31. At the same time, the sealing channel communicates with the via hole 31. If foreign matter enters the sealing channel from the outside, the foreign matter will directly enter the via hole 31, affecting the electrical equipment inside the via hole 31. A snap ring 16 is provided at the opening of the sealing channel close to the via hole 31, so that the snap ring 16 is snap-connected with the via hole 31, which can not only enhance the connection stability between the sealing sleeve 10 and the via hole 31, but also buffer the foreign matter entering the sealing channel, preventing the foreign matter from directly entering the via hole 31, which is beneficial to enhancing the sealing performance between the sealing sleeve 10 and the via hole 31.
[0062] In some embodiments, as Figure 1 and Figure 5 shown, the fixing member 32 is a stud located on the plate body 30. Connecting holes 40 communicating with each other are provided on the sealing connection part 12 and the protection connection part 21. A nest is provided in the connecting hole 40, and the stud passes through the connecting hole 40 through the nest to fixedly connect the sealing connection part 12, the protection connection part 21 and the plate body 30.
[0063] Specifically, the stud can be a projection welding stud, which is fixedly connected to the plate body 30, preventing the fixing member 32 from passing through the plate body 30 and entering the interior, affecting the sealing performance of the plate body 30, which is beneficial to improving the sealing performance of the sealing structure.
[0064] Specifically, a nest is provided in the connecting hole 40 of the sealing connection part 12 and the protection connection part 21. Connecting through the nest with the stud can prevent the sealing connection part 12 and the protection connection part 21 from being extruded and cracked when connected by the stud and the nut 50, which is beneficial to the connection stability between the sealing structure and the plate body 30, and further beneficial to improving the sealing performance of the sealing structure.
[0065] Exemplarily, the nest is a metal nest.
[0066] It should be noted that a plurality of waterproof raised ribs 15 are provided on one side of the sealing connection part 12 close to the plate body 30 and arranged around the connecting hole 40. As Figure 2 shown, the function of this waterproof raised rib 15 is the same as that of the waterproof raised rib 15 corresponding to the opening of the above-mentioned wire harness channel 11, both of which are to prevent water from entering the via hole 31 through the connecting hole 40 / this opening, which is beneficial to improving the sealing performance of the sealing sleeve 10, and further improving the sealing performance of the sealing structure.
[0067] Based on the same inventive concept, the present application also provides a vehicle, including the above-mentioned via hole sealing structure, and the technical effects produced are the same as those of the sealing structure, which will not be elaborated here.
[0068] Those of ordinary skill in the art should understand that any discussion of the above embodiments is merely exemplary and is not intended to imply that the scope of the present application (including the claims) is limited to these examples; under the concept of the present utility model, the technical features in the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations in different aspects of the present utility model as described above, and for the sake of brevity, they are not provided in detail.
[0069] The embodiments of the present utility model are intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
