Description

Technical Field

[0001] This utility model relates to the field of winch technology, specifically to a waterproof structure for a flip-top socket and a vehicle winch. Background Technology

[0002] Vehicle winches are traction devices installed on vehicles. When vehicles need to be towed, rescued, or used for self-rescue in the wild, the winch can assist in getting the vehicle out of trouble. Currently, Chinese Patent Publication No. CN203922544U discloses a waterproof electric winch. It has a triple waterproof structure by setting waterproof rings at the connection points of the motor assembly, winch drum assembly, and gearbox assembly. This provides triple waterproof protection for the entire electric winch during use, improving its waterproof performance and preventing rust on the internal components. In addition, in the above-mentioned waterproof electric winch structure, the winch is equipped with a socket. This socket is used to connect with the wiring harness on the control switch assembly to enable the control switch assembly to control the working status of the winch. However, in the above-mentioned prior art, the socket installed on the winch is exposed to the outside of the winch, which makes it easy for water to enter the socket, causing corrosion and even short circuits. This not only causes winch failure and shortens its service life, but also easily leads to fires due to short circuits. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a waterproof structure for a flip-top socket and a vehicle winch, which can waterproof the conductive socket located on the winch housing.

[0004] This utility model provides a waterproof flip-top socket structure, including a winch housing and a conductive socket. The winch housing has an assembly hole on its side wall, and an annular support platform is provided on the outer wall of the winch housing along the circumferential direction of the assembly hole. The outer end of the conductive socket is fixed to the support platform, and the inner end of the conductive socket extends into the winch housing through the assembly hole. The waterproof flip-top socket structure also includes a waterproof cover and a sealing ring. The sealing ring is fitted and fixed to the outer peripheral wall of the support platform. Two opposite sides of the waterproof cover form a hinge end and an operating end, respectively. The hinge end is rotatably connected to the winch housing located on one side of the support platform. An annular protrusion is provided on the side of the waterproof cover facing the support platform. When a hand grasps the operating end and drives the waterproof cover to rotate relative to the winch housing towards the support platform, the annular protrusion is fitted onto the outside of the support platform, and the sealing ring seals the gap between the annular protrusion and the support platform.

[0005] By adopting the above-described structure, when the waterproof cover rotates relative to the winch housing towards the support platform and the annular boss is fitted onto the outside of the support platform, the sealing ring can seal the gap between the annular boss and the support platform, thereby achieving the purpose of waterproofing the conductive socket. This prevents the socket from being corroded or short-circuited due to contact with water, effectively preventing winch malfunctions and extending the winch's service life. Furthermore, it prevents fires caused by short circuits, eliminating safety hazards.

[0006] In one possible implementation, an annular rib is provided on the outer peripheral wall of the sealing ring. The annular rib is located at the center of the sealing ring in the axial direction, and the outer surface of the annular rib forms an arc surface. By providing an annular rib on the outer peripheral wall of the sealing ring, the annular rib has the advantage of good deformability. Thus, after the annular boss is fitted onto the outside of the support platform, the outer peripheral wall of the sealing ring can be more reliably sealed against the inner peripheral wall of the annular boss under the action of the annular rib. Furthermore, since the outer surface of the annular rib forms an arc surface, the annular rib can more smoothly enter the inner cavity of the annular boss and seal against the inner wall of the annular boss during the process of fitting the annular boss onto the outside of the support platform.

[0007] In one possible implementation, an annular groove is provided on the outer peripheral wall of the support platform, and the inner edge of the sealing ring is embedded in the annular groove; an annular groove is provided on the inner peripheral wall of the sealing ring, and an annular locking block adapted to the annular groove is provided on the inner wall of the annular groove, the annular locking block and the annular groove engaging and locking together; by adopting this structure, since the inner edge of the sealing ring is embedded in the annular groove, the sealing ring can be reliably fastened to the support platform. Furthermore, under the engaging action of the annular locking block and the annular groove, the assembly firmness between the sealing ring and the support platform can be further improved, and a labyrinthine sealing structure can be formed between the sealing ring and the support platform, thereby improving the circumferential sealing effect between the sealing ring and the support platform and improving the waterproof performance.

[0008] In one possible implementation, an annular conical surface is provided on the inner wall of the end of the annular boss away from the waterproof cover. The annular conical surface is used to guide and cooperate with the outer wall of the annular rib so that the annular rib can slide into the inner cavity of the annular boss and be tightly sealed against the inner wall of the annular boss. By providing an annular conical surface on the inner wall of the end of the annular boss away from the waterproof cover, during the process of the annular boss being fitted onto the outer side of the support platform, the annular conical surface can cooperate and guide and cooperate with the outer wall of the annular rib so that the annular rib can slide into the inner cavity of the annular boss and be tightly sealed against the inner wall of the annular boss. This facilitates the fitting and tight sealing between the annular boss and the annular rib, and avoids the sealing ring and the annular rib being cut by the inner wall of the end of the annular boss away from the waterproof cover.

[0009] In one possible implementation, an opening slot is provided in the middle of the rear side of the hinge end, and a support block is provided on the outer wall of the winch housing located on one side of the support platform. The support block is loosely fitted in the opening slot. A support shaft is vertically inserted through the support block and is tightly fitted with the support block. A shaft hole is provided on both sides of the hinge end located in the vertical direction of the opening slot. The two ends of the support shaft are respectively inserted into one of the shaft holes and rotate with the shaft hole. With this structure, under the rotational engagement of the two ends of the support shaft in the axial direction with the shaft hole, the hinge end of the waterproof cover can be reliably rotatably connected to the winch housing located on one side of the support platform through the shaft hole and the support shaft.

[0010] In one possible implementation, torsion springs are fitted onto the outer sides of both ends of the support shaft in the axial direction. Two torsion springs are located in corresponding shaft holes, with one end of each spring connected to the support block and the other end connected to the hinge end. The torsion springs apply a torque to the waterproof cover, causing it to rotate relative to the winch housing, so that the annular boss actively engages with the outside of the support platform. With this structure, under the action of the two torsion springs, when the operating end of the waterproof cover is released, the torsion springs can apply a torque to the waterproof cover, causing it to rotate relative to the winch housing. The direction of rotation of the waterproof cover relative to the winch housing is the direction that drives the waterproof cover closer to the support platform, thereby enabling the annular boss to actively engage with the outside of the support platform. This prevents the waterproofing of the conductive socket from failing due to the user forgetting to attach the waterproof cover to the support platform.

[0011] In one possible implementation, the support block is provided with insertion holes corresponding to the two torsion springs. One end of each torsion spring is inserted into the corresponding insertion hole. Each shaft hole has a limiting groove on its inner wall, and the other end of each torsion spring is embedded in the corresponding limiting groove. With this structure, after one end of the torsion spring is inserted into the insertion hole and after the other end of the torsion spring is embedded in the limiting groove, both ends of the torsion spring can be reliably connected to the hinge ends of the support block and the waterproof cover, so that the torsion spring can reliably apply a torque to the waterproof cover to drive the waterproof cover to rotate relative to the winch housing.

[0023] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] See Figures 1-6As shown in the figure, this application discloses a waterproof structure for a flip-type socket, including a winch housing 1 and a conductive socket 2; an assembly hole 11 is provided on the side wall of the winch housing 1, and an annular support platform 12 is provided on the outer wall of the winch housing 1 along the circumferential direction of the assembly hole 11; the outer end of the conductive socket 2 is fixed on the support platform 12, and the inner end of the conductive socket 2 extends into the winch housing 1 through the assembly hole 11; the waterproof structure for the flip-type socket also includes a waterproof cover 3 and a sealing ring 4; the sealing ring 4 is sleeved and fixed on the support platform 1. On the outer peripheral wall of 2, two opposite sides of the waterproof cover 3 form a hinge end 31 and an operating end 32, respectively. The hinge end 31 is rotatably connected to the winch housing 1 located on one side of the support platform 12. An annular boss 33 is provided on the side of the waterproof cover 3 facing the support platform 12. When the hand grasps the operating end 32 and drives the waterproof cover 3 to rotate relative to the winch housing 1 towards the support platform 12, the annular boss 33 is used to fit onto the outside of the support platform 12, and the sealing ring 4 is used to seal the gap between the annular boss 33 and the support platform 12.

[0025] See you again Figure 5 and Figure 6 As shown, an annular rib 41 is provided on the outer peripheral wall of the sealing ring 4. The annular rib 41 is located in the middle of the axial direction of the sealing ring 4, and the outer surface of the annular rib 41 forms an arc surface. By providing the annular rib 41 on the outer peripheral wall of the sealing ring 4, the annular rib 41 has the advantage of good deformability. Thus, after the annular boss 33 is sleeved on the outside of the support platform 12, under the action of the annular rib 41, the outer peripheral wall of the sealing ring 4 can be more reliably sealed against the inner peripheral wall of the annular boss 33. Moreover, since the outer surface of the annular rib 41 forms an arc surface, during the process of the annular boss 33 being sleeved on the outside of the support platform 12, the annular rib 41 can more smoothly enter the inner cavity of the annular boss 33 and seal against the inner wall of the annular boss 33. In addition, the annular rib 41 is integrally formed on the outer peripheral wall of the sealing ring 4, which has the advantage of high connection strength between the annular rib 41 and the sealing ring 4.

[0026] See you again Figure 5 and Figure 6As shown, an annular groove 121 is provided on the outer peripheral wall of the support platform 12, and the inner edge of the sealing ring 4 is embedded in the annular groove 121; an annular groove 42 is provided on the inner peripheral wall of the sealing ring 4, and an annular block 122 adapted to the annular groove 42 is provided on the inner wall of the annular groove 121, and the annular block 122 and the annular groove 42 are engaged and locked together; by adopting this structure, since the inner edge of the sealing ring 4 is embedded in the annular groove 121, the sealing ring 4 can be reliably fastened to the support platform 12. Furthermore, under the engaging action of the annular block 122 and the annular groove 42, the assembly firmness of the sealing ring 4 and the support platform 12 can be further improved, and a labyrinth-like sealing structure can be formed between the sealing ring 4 and the support platform 12, thereby improving the circumferential sealing effect between the sealing ring 4 and the support platform 12 and improving the waterproof performance.

[0027] See you again Figure 4 and Figure 6 As shown, an annular conical surface 331 is provided on the inner wall of the end of the annular boss 33 away from the waterproof cover 3. The annular conical surface 331 is used to cooperate with the outer wall of the annular rib 41 for guidance so that the annular rib 41 can slide into the inner cavity of the annular boss 33 and be tightly sealed against the inner wall of the annular boss 33. After the annular conical surface 331 is provided on the inner wall of the end of the annular boss 33 away from the waterproof cover 3, during the process of the annular boss 33 being fitted onto the outer side of the support platform 12, the annular conical surface 331 can cooperate with the outer wall of the annular rib 41 for guidance so that the annular rib 41 can slide into the inner cavity of the annular boss 33 and be tightly sealed against the inner wall of the annular boss 33. This facilitates the fitting and tight sealing between the annular boss 33 and the annular rib 41, and avoids the sealing ring 4 and the annular rib 41 being cut by the inner wall of the end of the annular boss 33 away from the waterproof cover 3.

[0028] See you again Figures 2-4 As shown, an opening groove 311 is provided in the middle of the rear side of the hinge end 31. A support block 13 is provided on the outer wall of the winch housing 1 located on one side of the support platform 12. The support block 13 is clearance-fitted in the opening groove 311. A support shaft 5 is vertically inserted on the support block 13. The support shaft 5 is tightly fitted with the support block 13. A shaft hole 312 is provided on both sides of the hinge end 31 in the vertical direction of the opening groove 311. The two ends of the support shaft 5 are respectively inserted into one of the shaft holes 312 and rotate with the shaft hole 312. With this structure, under the rotational cooperation between the two ends of the support shaft 5 in the axial direction and the shaft hole 312, the hinge end 31 of the waterproof cover 3 can be reliably rotatably connected to the winch housing 1 located on one side of the support platform 12 through the shaft hole 312 and the support shaft 5.

[0029] See you again Figures 2-4As shown, torsion springs 6 are sleeved on the outer sides of both ends of the support shaft 5 in the axial direction. The two torsion springs 6 are respectively located in the shaft holes 312 on the corresponding sides. One end of each torsion spring 6 is connected to the support block 13, and the other end of each torsion spring 6 is connected to the hinge end 31. The torsion springs 6 are used to apply a torque to the waterproof cover 3 to drive the waterproof cover 3 to rotate relative to the winch housing 1, so that the annular boss 33 actively sleeves onto the outside of the support platform 12. With this structure, under the action of the two torsion springs 6, when the operating end 32 of the waterproof cover 3 is released, the torsion springs 6 can apply a torque to the waterproof cover 3 to drive the waterproof cover 3 to rotate relative to the winch housing 1. The direction of rotation of the waterproof cover 3 relative to the winch housing 1 is the direction that drives the waterproof cover 3 to move closer to the support platform 12, so that the annular boss 33 can actively sleeve onto the outside of the support platform 12, thereby avoiding the situation where the waterproof socket 2 fails due to the user forgetting to put the waterproof cover 3 on the support platform 12.

[0030] See you again Figures 2-4 As shown, the support block 13 is provided with insertion holes 131 corresponding to the two torsion springs 6. One end of each torsion spring 6 is inserted into the corresponding insertion hole 131. Each shaft hole 312 has a limiting groove 313 on its inner wall. The other end of each torsion spring 6 is embedded in the corresponding limiting groove 313. With this structure, after one end of the torsion spring 6 is inserted into the insertion hole 131 and after the other end of the torsion spring 6 is embedded in the limiting groove 313, both ends of the torsion spring 6 can be reliably connected to the support block 13 and the hinge end 31 of the waterproof cover 3, so that the torsion spring 6 can reliably apply a torque to the waterproof cover 3 to drive the waterproof cover 3 to rotate relative to the winch housing 1.
