[0028] With the development of new energy vehicles, the placement of slow-charging stations has become increasingly diverse. Furthermore, new requirements have been placed on the unlocking devices of electronic locks, requiring the cable to be waterproofed by being integrated into the interior and exterior of the vehicle. This utility model provides a cable sealing assembly with a simple structure, convenient operation, ease of use and management, and excellent practical effect.

[0029] Please refer to Figures 1 to 5 This utility model proposes a cable sealing assembly 100 for use in vehicles. The vehicle body has a body hole A, including a rubber sleeve 10 and a cable sleeve 20. The rubber sleeve 10 is interference-fitted with the vehicle body hole A and has an inlet 10A and an outlet 10B. The cable sleeve 20 has a first end 21 and a second end 22. The first end 21 of the cable sleeve 10 passes through the inlet 10A into the rubber sleeve 10 and exits through the outlet 10B, extending beyond the inlet 10A and the outlet 10B. A sealing element 30 is provided on the outside of the cable sleeve 20 located inside the rubber sleeve 10. A cable 40 is provided inside the cable sleeve 20. The cable 40 has a connecting end 41 and a free end 42, which respectively pass through the second end 22 and the first end 21 of the cable sleeve 20.

[0030] It is understandable that the means of transportation can be a gasoline-powered car, an electric car, an airplane, a ship, etc., and is not limited here. The rubber sleeve 10 is typically made of elastic rubber. The outer diameter of the rubber sleeve 10 is interference-fitted with the vehicle body hole A, meaning the outer diameter of the rubber sleeve 10 is slightly larger than the diameter of the vehicle body hole A. Due to its elasticity, the rubber sleeve 10 is pressed tightly against the edge of the vehicle body hole A through the interference fit. This tight contact forms the first sealing barrier, preventing water / dust from directly entering the vehicle body hole A. The elastic deformation of the rubber sleeve 10 can effectively compensate for the dimensional tolerances and irregular shapes of the opening in the vehicle body sheet metal, ensuring a reliable static seal with the vehicle body hole A under various tolerances. The cable sleeve 20 is a tubular component that wraps around or guides the cable 40. It can be a metal tube or a plastic tube, and the cable sleeve 20 runs through the entire rubber sleeve 10. Inside the rubber sleeve 10, a seal 30 located outside the cable sleeve 20 is compressed between the outer wall of the cable sleeve 20 and the inner wall of the rubber sleeve 10. This compression mainly generates radial force, causing the seal 30 to adhere tightly to the outer surface of the cable sleeve 20 and the inner surface of the rubber sleeve 10. This allows the cable sleeve 20 to undergo axial movement, such as slight swaying or shifting during the operation of the shift cable 40. The seal 30 can also follow this movement and maintain effective radial sealing contact, continuously preventing the medium that might bypass the first sealing barrier from leaking along the axial path. The first sealing barrier seals the gap between the rubber sleeve 10 and the vehicle body sheet metal, and the second sealing barrier seals the gap between the rubber sleeve 10 and the cable sleeve 20. The cable sleeve 20 contains a cable 40, which has a connecting end 41 and a free end 42, respectively, which protrude from the second end 22 and the first end 21 of the cable sleeve 20. Since the cable 40 moves in a pushing, pulling, or swinging motion within the cable sleeve 20, and both ends of the cable sleeve 20 are usually open or lead to specific areas, such as gearboxes or unlocking mechanisms, the combination of these two barriers provides an effective circumferential and axial seal for the cable 40 itself and the path it travels through. This blocks the possible path of the external environment entering the channel through which the cable 40 passes via the vehicle body hole A, continuously sealing the tiny gap between the outer wall of the cable sleeve 20 and the inner wall of the rubber sleeve 10. This effectively prevents external water, dust, gas, etc., from invading the interior of the rubber sleeve 10 or passing through the rubber sleeve 10 into the vehicle body along the moving cable 20, thus achieving an all-around seal.

[0031] This utility model's cable sealing assembly 100 forms a first sealing barrier through the interference fit between the rubber sleeve 10 and the vehicle body hole A. The elastic deformation of the rubber sleeve 10 can compensate for the sheet metal tolerances of the vehicle body, forming a sealing structure between the rubber sleeve 10 and the vehicle body. A sealing element 30 is set between the rubber sleeve 10 and the cable sleeve 20 to form a second sealing barrier. A dynamic seal is formed through radial compression, effectively blocking the axial water seepage path. Thus, effective circumferential and axial sealing is provided for the cable 40 located inside the cable sleeve 20 and the path it passes through, achieving all-round sealing. This utility model's cable sealing assembly 100 has a simple structure and is easy to operate.

[0032] This utility model provides an embodiment, please refer to it. Figures 1-4 The rubber sleeve 10 has a stop portion 11, a connecting portion 12 and a sleeve portion 13 connected in sequence. The stop portion 11 is interference-fitted with the vehicle body hole A. The cable sleeve 20 passes through the stop portion 11, the connecting portion 12 and the sleeve portion 13 in sequence and extends out of the stop portion 11 and the sleeve portion 13. A sealing element 30 is provided on the outside of the cable sleeve 20 located in the sleeve portion 13.

[0033] Understandably, the stop portion 11 is interference-fitted with the vehicle body hole A. After being pressed into the vehicle body hole A, it undergoes radial elastic deformation to compensate for sheet metal tolerances, allowing the vehicle body to maintain a seal during vibration / deformation, thus forming the first sealing barrier. The connecting portion 12 connects the stop portion 11 and the sleeve portion 13, providing a deformation buffer zone. The sleeve portion 13 accommodates and compresses the seal 30, forming the second sealing barrier. The sleeve portion 13 matches the shape of the cable sleeve 20. Specifically, both the sleeve portion 13 and the cable sleeve 20 are tubular, forming an annular cavity between them. The seal 30 is located in the annular cavity, forming a dynamic seal through radial compression, effectively blocking the axial water seepage path. The stop portion 11, connecting portion 12, and sleeve portion 13 can be integrally formed or separately provided; no limitation is made here.

[0034] This utility model provides an embodiment, please refer to it. Figures 1-4 The stop part 11 has a stop boss 111, which abuts against the outer surface of the vehicle body. The end of the stop part 11 away from the stop boss 111 is provided with a limiting groove 11A that matches the hole A of the vehicle body.

[0035] Understandably, the stop boss 111 further increases the contact area between the rubber sleeve 10 and the vehicle body. The stop boss 111 can cover the edge of the vehicle body hole A, preventing water from entering the assembly gap along the sheet metal plane. The limiting groove 11A provides mechanical locking between the rubber sleeve 10 and the vehicle body hole A. The depth of the limiting groove 11A needs to be greater than the thickness of the vehicle body sheet metal. When the limiting groove 11A is engaged in the vehicle body hole A, it will generate significant resistance, which can be used to determine whether the assembly is in place. The stop boss 111 can be a variable-height stepped boss to adapt to vehicles with different paint thicknesses.

[0036] This utility model provides an embodiment, please refer to it. Figure 3 , Figure 4 The diameter of the limiting groove 11A gradually decreases along the direction from the stop portion 11 to the sleeve portion 13.

[0037] Understandably, to prevent the rubber sleeve 10 from easily rotating or moving axially within the vehicle body hole A, the diameter of the limiting groove 11A gradually decreases along the direction from the stop portion 11 towards the sleeve portion 13. Specifically, the limiting groove 11A can be conical in shape. The conical shape allows the limiting groove 11A to form a progressive interference fit with the vehicle body hole A, which not only avoids sudden stress changes in the rubber sleeve 10 but also further restricts the rotation or axial movement of the rubber sleeve 10. Of course, the limiting groove 11A can also be other shapes that match the vehicle body hole A, as long as the diameter of the limiting groove 11A gradually decreases along the direction from the stop portion 11 towards the sleeve portion 13.

[0038] This utility model provides an embodiment, please refer to it. Figure 1 , Figure 2 , Figure 5 The connecting part 12 is located inside the vehicle body and has an inlet end 121 and an outlet end 122. The diameter of the inlet end 121 is larger than the diameter of the outlet end 122. The inlet end 121 is connected to the end of the stop part 11 away from the stop boss 111, and the outlet end 122 is connected to the sleeve part 13.

[0039] Understandably, the connecting part 12 is located inside the vehicle body and has an inlet end 121 and an outlet end 122. The diameter of the inlet end 121 is larger than the diameter of the outlet end 122. The inlet end 121 is connected to the end of the stop part 11 away from the stop boss 111, and the outlet end 122 is connected to the sleeve part 13 to provide a deformation buffer zone.

[0040] This utility model provides an embodiment, please refer to it. Figure 1 , Figure 2The sealing element 30 has a sealing layer 31 and a fixing layer 32. The outer side of the cable sleeve 20 is provided with a sealing layer 31 and a fixing layer 32 in sequence. At least a portion of the sealing layer 31 extends out of the outlet 10B of the rubber sleeve 10, and at least a portion of the fixing layer 32 extends out of the inlet 10A and outlet 10B of the rubber sleeve 10.

[0041] Understandably, in this embodiment, the sealing element 30 adopts a separate configuration of sealing layer 31 and fixing layer 32. Sealing layer 31 is a non-curing waterproof cement, a high-performance sealing material whose core characteristic is that it never hardens, maintaining a viscoelastic state and achieving long-term sealing through physical adhesion and adaptive deformation. Specifically, non-curing waterproof cement includes butyl rubber, silicone rubber, and other putties. Using non-curing waterproof cement in sealing layer 31 achieves a long-lasting dynamic seal between rubber sleeve 10 and cable sleeve 20. Fixing layer 32 wraps around the outside of sealing layer 31, further fixing sealing layer 31 and constraining its sealing range and deformation. Fixing layer 31 can be made of waterproof polymer tape, heat shrink tubing, or other waterproof materials to achieve both fixing and sealing effects. Fixing layer 31 and sealing layer 32 can be assembled using tape wrapping or heat shrink tubing connection.

[0042] This utility model provides an embodiment, please refer to it. Figure 1 , Figure 2 The rubber sleeve 10 near the outlet 10B and the first end 21 of the cable sleeve 20 are provided with a waterproof layer 50.

[0043] Understandably, the end of the rubber sleeve 10 near the outlet 10B and the outside of the first end 21 of the cable sleeve 20 are provided with a waterproof layer 50, which can further improve the waterproof performance of the cable sealing assembly 100. The waterproof layer 50 can be made of waterproof tape or heat shrink tubing, and there is no limitation here.

[0044] This utility model provides an embodiment, please refer to it. Figure 5 The first end 21 of the cable sleeve 20 is fixedly connected to the interior of the vehicle, and the second end 22 is fixedly connected to the charging seat unlocking device 200 of the vehicle.

[0045] This utility model provides an embodiment, please refer to it. Figure 5 The connection end 41 is connected to the unlocking device 200 of the charging dock of the vehicle so as to control the switch of the unlocking device 200 through the free end 42.

[0046] The assembly process of the cable sealing assembly 100 of this utility model is as follows: the cable 40 passes through the cable sleeve 20 and extends out of the first end 21 and the second end 22 of the cable sleeve. The cable sleeve 20 is coated with a sealing layer 31, and then a fixing layer 32 is wrapped or fitted around it. The cable 40 is then inserted into the through part 13 of the rubber sleeve 10. The sealing layer 31 creeps, forming a dynamic seal between the inner wall of the through part 13 of the rubber sleeve 10 and the outer wall of the cable sleeve 20. Finally, a waterproof layer 50 is wrapped or fitted around the first end 21 of the cable sleeve 20 at the end of the rubber sleeve 10 near the outlet 10B, thus completing the assembly of the cable sealing assembly 100.

[0047] In this embodiment, a new energy vehicle is used as an example of a transportation vehicle. When in use, the limiting groove 11A of the stop portion 11 of the rubber sleeve 10 of the cable sealing assembly 100 is inserted into the body hole A of the vehicle. In this way, a person sitting in the vehicle can control the opening and closing of the unlocking device 200 by pulling the free end 42 of the cable 40.
