When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0029] This application proposes a sealed connection structure, comprising:

[0030] A base 10, wherein the base 10 is provided with a connecting hole 11, and a first limiting portion is provided on the hole wall of the connecting hole 11; and

[0031] A sealed connector is provided with a second limiting portion on the outer surface of the sealed connector. The sealed connector is inserted into the connecting hole 11 so that the first limiting portion is limited to the second limiting portion.

[0032] The sealing connection structure of the technical solution of the present application includes a base 10 and a sealing connector. The base 10 is provided with a connecting hole 11, and the sealing connector is inserted into the connecting hole 11, so that the sealing connector can be installed and fixed without the aid of other installation tools; further, a first limiting portion is provided on the hole wall of the connecting hole 11, and a second limiting portion is provided on the outer surface of the sealing connector. When the sealing connector is inserted into the connecting hole 11, the first limiting portion is limited to the second limiting portion, thereby reducing the possibility of the sealing connector being squeezed out of the connecting hole 11 due to internal extrusion, thereby improving the stability of the installation of the sealing connector.

[0033] In this embodiment, one of the first limiting portion and the second limiting portion is a limiting groove, and the other is a limiting protrusion 211. When the sealing connector is inserted into the mounting hole, the limiting protrusion 211 is limited in the limiting groove, thereby improving the stability of the installation of the sealing connector.

[0034] In this embodiment, the limiting protrusion 211 is arranged at the bottom of the outer surface of the sealing connection, or the limiting protrusion 211 is arranged at the middle position of the outer peripheral surface of the sealing connector; further, the limiting protrusion 211 is made of a flexible material, so that when the sealing connector is inserted into the connection hole 11, the limiting protrusion 211 is deformed, and then when inserted into the limiting groove, the deformation is restored and it is limited in the limiting groove, so that the sealing connector is firmly limited in the connection hole 11, thereby increasing the stability of the sealing connector.

[0035] There may be a plurality of limiting protrusions 211 and limiting grooves, with one limiting protrusion 211 corresponding to one limiting groove. By providing a plurality of limiting protrusions 211 and limiting grooves, the stability of the sealed connector may be further increased.

[0036] It can be understood that when the sealing connector needs to be disassembled, it is necessary to pull out the sealing connector from bottom to top, and then pull out the limiting protrusion 211 from the limiting groove. Therefore, if the upper groove surface of the limiting groove is tilted downward from the outside to the inside, the limiting protrusion 211 will be pulled with a large force when the sealing connector is pulled out, and the limiting protrusion 211 will be easily damaged. Therefore, in this embodiment, the upper groove surface of the limiting groove is tilted upward from the outside to the inside, thereby reducing the possibility of damage to the sealing connector during disassembly, thereby increasing the service life of the sealing connector.

[0037] Furthermore, the limiting protrusion 211 and the limiting groove are arranged in a ring shape. The ring shape makes the connection between the sealing connector and the connecting hole 11 more stable on the one hand, and makes the sealing effect between the sealing connector and the base 10 better on the other hand, thereby reducing the entry of debris into the connecting hole 11, thereby increasing the cleanliness of the sealing connection structure, reducing the amount of cleaning, and improving the user experience.

[0038] Specifically, the sealing connector includes a first sealing ring 21 and a second sealing ring 22. The outer surface of the first sealing ring 21 is used to seal and abut against the wall surface of the connecting hole 11. The first limiting portion is provided on the outer surface of the first sealing ring 21. The outer edge of the second sealing ring 22 is connected to the first sealing ring 21, and the inner edge extends inward in a direction away from the first sealing ring 21. The inner edge of the second sealing ring 22 is used to seal and abut against the outer surface of the male head 30 inserted into the connecting hole 11. When the male head 30 is detached from the sealing connector, a seal is formed between the inner edge of the second sealing ring 22 and the first sealing ring 21. Tolerance gap; when the male head 30 is detached from the sealing connector, a tolerance gap is formed between the inner edge of the second sealing ring 22 and the first sealing ring 21. When the male head 30 is inserted into the sealing connector, the inner edge of the second sealing ring 22 is used to seal against the outer surface of the male head 30 inserted into the connecting hole 11, so that when the male head 30 is inserted into the second sealing ring 22, the inner edge of the second sealing ring 22 moves toward the direction close to the first sealing ring 21, so that the tolerance gap makes the first sealing ring 21 and the second sealing ring 22 have a larger radial tolerance, thereby reducing the dependence on the accuracy of the male head 30 and the sealing connector, and reducing the production cost.

[0039] At the same time, the male connector 30 can push the free end of the second sealing ring 22 to move toward the direction close to the first sealing ring 21, so that the male connector 30 can be plugged in through the tolerance gap even in an eccentric state. At the same time, the second sealing ring 22 always has a tendency to restore its deformation, so that the second sealing ring 22 and the male connector 30 are always sealed, thereby reducing the difficulty of connecting the male connector 30 and the sealing connector and improving the assembly efficiency of the male connector 30 and the sealing connector.

[0040] Furthermore, the sealing connector also includes an inner skeleton 25, which is embedded in the second sealing ring 22. The inner skeleton 25 increases the rigidity of the second sealing ring 22, so that the second sealing ring 22 will not swing at will in the initial state, and also enhances the sealing effect when the second sealing ring 22 abuts against the male head 30.

[0041] In one embodiment, the second sealing ring 22 includes a first sealing portion 221 arranged obliquely, a second sealing portion 222 arranged horizontally, and a third sealing portion 223 arranged obliquely. The second sealing ring 22 also includes a mounting portion connected to the second sealing portion 222, and the mounting portion is located on the side of the second sealing portion 222 facing the third sealing portion 223. The inner skeleton 25 is embedded in the mounting portion, wherein the third sealing portion 223 arranged obliquely is in sealing contact with the outer wall surface of the male head 30, and the second sealing portion 222 is arranged horizontally to facilitate the installation and fixation of the mounting portion and the inner skeleton 25. The mounting portion and the second sealing portion 222 can be integrally injection molded, or can be fixed to the second sealing portion 222 by hot-melt.

[0042] In one embodiment, a sealing protrusion 224 is provided on the side of the third sealing portion 223 facing the mounting portion. When the male connector 30 is inserted into the sealed connector, the outer wall surface of the male connector 30 is sealed and abutted against the third sealing portion 223. At this time, the third sealing portion 223 is bent and deformed in the direction close to the mounting portion, and can then abut against the mounting portion through the sealing protrusion 224, thereby limiting the assembly eccentricity of the male connector 30 and ensuring that the eccentricity is within the design range. Therefore, the size and number of the sealing protrusions 224 can be set according to actual conditions.

[0043] In this embodiment, a mounting protrusion is provided on the outer wall surface of the first sealing ring 21, and the mounting protrusion is used to be sealed and connected to the base 10; it can be understood that the first sealing ring 21 has a certain deformation amount, and the deformation generated by the first sealing ring 21 and the cooperation with the mounting protrusion enable it to be sealed and abutted with the base 10, thereby facilitating the installation of the first sealing ring 21 and improving the installation efficiency of the first sealing ring 21.

[0044] The sealing connector also includes an exoskeleton 24, which is embedded in the first sealing ring 21. The exoskeleton 24 enhances the rigidity of the first sealing ring 21, controls the deformation of the first sealing ring 21 within a predetermined range, and prevents the first sealing ring 21 from excessively shrinking inward, thereby making the first sealing ring 21 firmly sealed against the wall of the connecting hole 11 through the mounting protrusion, thereby increasing the connection strength and sealing effect between the first sealing ring 21 and the base 10.

[0045] In this embodiment, the outer skeleton 24 and the first sealing ring 21 are integrally injection-molded. Of course, in other embodiments, the outer skeleton 24 may be fixed in the first sealing ring 21 by hot melting.

[0046] It can be understood that since the material of the first sealing ring 21 is mostly flexible materials such as silicone and rubber, the first sealing ring 21 is in a liquid state during injection molding. Therefore, when the exoskeleton 24 and the first sealing ring 21 are injection molded, the exoskeleton 24 needs to be limited and fixed first so that the liquid first sealing ring 21 can wrap the entire exoskeleton 24 to prevent the exoskeleton 24 from sinking to the bottom of the liquid first sealing ring 21. Therefore, in this embodiment, a mold hole is provided on the first sealing ring 21. When the exoskeleton 24 and the first sealing ring 21 are injection molded, the mold hole is used for the external structure to pass through to position the exoskeleton 24; if the exoskeleton 24 is a magnetic material such as iron, the exoskeleton 24 can be positioned by magnetic attraction through the mold hole. Of course, a vacuum adsorption device can also be set to pass through the mold hole to vacuum adsorb and fix the exoskeleton 24. Of course, it can also be bonded.

[0047] The present application also proposes a vehicle, which includes a sealed connection structure. The specific structure of the sealed connection structure refers to the above-mentioned embodiments. Since the present application adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0048] The above description is merely an embodiment of the present application and does not limit the patent scope of the present application. All equivalent structural transformations made using the contents of the present application specification and drawings under the inventive concept of the present application, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
