[0034] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0035] The present invention provides a waterproof socket, such as Figure 1 As shown, the socket cover 12, the sealing gasket 21, the elastic member 22 and the housing 43 are included. The socket cover 12 cooperates with the housing 43 to form a receiving space, and the sealing gasket 21 and the elastic member 22 are arranged in the receiving space. The socket cover 12 is provided with a plug hole 13, and the plug hole 13 is opposite to the sealing gasket 21. The elastic member 22 is connected to the sealing gasket 21 to apply a thrust to the sealing gasket 21 and seal the plug hole 13. Optionally, the elastic member 22 is a spring.

[0036] like Figure 1 As shown, by setting the socket cover 12, the sealing gasket 21, the elastic member 22 and the shell 43, the socket cover 12 cooperates with the shell 43 to form a accommodating space, the sealing gasket 21 and the elastic member 22 are arranged in the accommodating space, the socket cover 12 is provided with a socket 13, the socket 13 is opposite to the sealing gasket 21, the elastic member 22 is connected to the sealing gasket 21, and the elastic member 22 applies a thrust to the sealing gasket 21 so that the sealing gasket 21 is inserted into the socket 13 to seal the socket 13, thereby achieving a waterproof effect.

[0037] In one embodiment, Figure 3 As shown, a groove is provided around the insertion hole 13 of the socket upper cover 12, in which an upper cover plug sealing gasket 11 of the same shape is fixed. When the plug is inserted, the upper cover plug sealing gasket 11 fits tightly against the lower wall of the plug body.

[0038] In one embodiment, Figure 1 As shown, an upper cover plug sealing gasket 11 is fixed around the insertion hole 13 of the socket upper cover 12. When the plug is inserted, the upper cover plug sealing gasket 11 is tightly fitted with the lower wall of the plug body.

[0039] Optionally, the shape of the upper cover plug sealing gasket 11 can be a polygon with a hollow center, an ellipse, or an irregular shape.

[0040] Optionally, the upper cover plug sealing gasket 11 may be made of a material having certain compression elasticity. Optionally, the material of the upper cover plug sealing gasket 11 may specifically be, but not limited to, silicone or rubber material.

[0041] Optionally, the upper cover plug 12 and the sealing gasket 21 may be made of, but not limited to, flame-retardant plastic material.

[0042] Specifically, the above arrangement forms the first waterproof structure of the waterproof socket. When there is water in the surrounding environment of the socket, the water is blocked outside the socket hole 13 of the upper cover plug, so that water cannot enter the socket hole 13, so that the socket hole 13 of the upper cover plug is in a sealed state.

[0043] In one embodiment, Figure 3 As shown, the socket cover 12 further includes a sealing gasket 14, one end of which is connected to the housing 43, and the jack 13 further includes a sealing gasket plug hole 15, which is opposite to the jack 13 of the cover plug. The inner wall of the sealing gasket plug hole 15 abuts against the plug terminal or the sealing gasket 21 to seal the sealing gasket plug hole 15.

[0044] In one embodiment, the elastic member 22 is connected to the sealing gasket 21 , and the elastic member 22 applies a thrust to the sealing gasket 21 so that the sealing gasket 21 is inserted into the sealing gasket plug hole 15 to seal the sealing gasket plug hole 15 .

[0045] Optionally, the material of the sealing pad 14 may be a material with certain compression elasticity. Optionally, the material of the sealing pad 14 may specifically be, but not limited to, silicone or rubber.

[0046] In one embodiment, Figure 2 As shown, a protrusion 16 is formed on the inner wall of the plug hole 15 of the sealing mat. The protrusion 16 and the plug terminal or the sealing gasket 21 are squeezed to allow the plug terminal or the sealing gasket 21 to pass through the plug hole 15 of the sealing mat while the side of the plug terminal or the sealing gasket 21 is tightly fitted with the hole wall to achieve the sealing of the plug hole 15 of the sealing mat.

[0047] In one embodiment, Figure 6 As shown, a protrusion 16 is formed on the inner wall of the sealing pad plug hole 15. The protrusion 16 is annular and is squeezed with the plug terminal or the sealing gasket 21 so that the plug terminal or the sealing gasket 21 can pass through the sealing pad plug hole 15 while the side of the plug terminal or the sealing gasket 21 is tightly fitted with the hole wall to achieve sealing of the sealing pad plug hole 15.

[0048] Specifically, the above arrangement forms a second waterproof structure of the waterproof socket. When external water enters the socket 13 , it can be blocked outside the sealing plug hole 15 , so that the external water cannot enter the sealing plug hole 15 , thereby sealing the sealing plug hole 15 .

[0049] An embodiment, such as Figure 2 As shown, the waterproof socket also includes a conductor 23, and a clamping portion is provided at one end of the conductor 23 close to the socket cover 12. The sealing gasket 21 and the clamping portion can slide relatively and abut against the plug terminal when the plug terminal is pushed in.

[0050] Optionally, the conductor 23 may be a material having a conductive property. Optionally, the conductor 23 may specifically be, but is not limited to, a plug-in copper busbar.

[0051] Specifically, the above arrangement fixes the position of the sealing gasket 21 so that the sealing gasket 21 can exactly abut against the plug terminal when the plug terminal is inserted.

[0052] An embodiment, such as Figure 2 As shown, the waterproof socket further includes a conductor 23 , which is connected to the housing 43 . A through hole 26 is provided at the bottom of the conductor 23 , and the elastic member 22 is fixed to the housing 43 through the through hole 26 .

[0053] Specifically, the above arrangement determines the position of the elastic member 22 and fixes the position of the conductor 23 by limiting and fixing the elastic member 22 on the through hole 26 at the bottom of the conductor 23 and the housing 43 .

[0054] An embodiment, such as Figure 4 As shown, the waterproof socket also includes a conductor 23, a sealing gasket limiting column 25 is fixed on the conductor 23, a waist-shaped hole 24 is provided on the sealing gasket 21, and the waist-shaped hole 24 extends in the second direction at one end of the sealing gasket 21 close to the upper cover plug, and the sealing gasket limiting column 25 extends horizontally and is inserted in the waist-shaped hole 24, and the sealing gasket 21 can move longitudinally within the range limited by the waist-shaped hole 24. The second direction is the direction of insertion of the plug terminal.

[0055] Optionally, the sealing gasket limiting column 25 may be made of, but is not limited to, a flame retardant plastic material.

[0056] Specifically, the above-mentioned setting limits the movement position of the sealing gasket 21, preventing the protrusion 27 from moving too much in the second direction and crushing the micro switch 31 when the socket is inserted too deeply, and the sealing gasket 21 from moving too much in the second direction and crushing the elastic part 22. The second direction is the direction of insertion of the plug terminal.

[0057] An embodiment, such as Figure 1 As shown, when the plug terminal is pulled out, the elastic member 22 pushes the sealing gasket 21 to move in the first direction; Figure 2As shown, when the plug terminal is inserted, the plug terminal pushes the sealing gasket 21 to move in the second direction. The first direction is the direction in which the plug terminal is pulled out, and the second direction is the direction in which the plug terminal is inserted.

[0058] An embodiment, such as Figure 5 As shown, the waterproof socket further includes a micro switch 31 and a conductor 23, the conductor 23 is connected to the micro switch 31, and the on and off of the power supply is controlled by the opening and closing of the micro switch 31; a protrusion 27 is provided on one side of the sealing gasket 21, when the plug terminal is inserted, the plug terminal abuts against the sealing gasket 21, and the plug terminal pushes the sealing gasket 21 to move in the second direction, so that the protrusion 27 moves in the second direction to press the micro switch 31, so that the circuit is connected. The second direction is the direction of the plug terminal insertion.

[0059] Specifically, the above arrangement forms a circuit switch arranged in the socket. When the plug is inserted, the circuit is open, and when the plug is pulled out, the circuit is disconnected, which has an effect of preventing accidental touch and reducing the risk of leakage.

[0060] An embodiment, such as Figure 1 As shown, the socket cover 12 also includes a sealing gasket 14, and the plug hole 13 also includes a sealing gasket plug hole 15. When the plug terminal is pulled out, the elastic member 22 pushes the sealing gasket 21 to move in the first direction, and the sealing gasket 21 seals the sealing gasket plug hole 15 to seal the sealing gasket plug hole 15; Figure 2 As shown, when the plug terminal is inserted, the sealing gasket 21 moves in the second direction, the upper cover plug sealing gasket 11 abuts against the lower wall of the plug body to seal the insertion hole 13, and the plug terminal abuts against the inner wall of the sealing gasket plug hole 15 to seal the sealing gasket plug hole 15. The first direction is the direction in which the plug terminal is pulled out, and the second direction is the direction in which the plug terminal is inserted.

[0061] Specifically, the above arrangement enables the socket to achieve an effective waterproof function both when the plug terminal is pulled out and when the plug terminal is inserted.

[0062] An embodiment, such as Figure 1 As shown, when the plug terminal is pulled out, the elastic force released by the elastic member 22 pushes the sealing gasket 21 to move in the first direction. At this time, the protrusion 27 moves in the first direction, the micro switch 31 is released, and the circuit is disconnected; Figure 2 As shown, when the plug terminal is inserted, the plug terminal pushes the sealing gasket 21 to move in the second direction, at which time, the protrusion 27 moves in the second direction, the micro switch 31 is pressed, and the circuit is connected. The first direction is the direction in which the plug terminal is pulled out, and the second direction is the direction in which the plug terminal is inserted.

[0063] Specifically, the above arrangement realizes that the circuit is in a connected state when the plug terminal is inserted, and the circuit is in a disconnected state when the plug terminal is pulled out, thereby effectively preventing accidental touches.

[0064] An embodiment, such as Figure 3 As shown, the housing 43 includes a socket inner shell 41 and a socket outer shell 42 . The socket inner shell 41 is inside the socket outer shell 42 . A protrusion 45 is provided inside the socket outer shell 42 . The socket inner shell 41 has a flange 46 outside. The socket inner shell flange 46 overlaps the socket outer shell protrusion 45 .

[0065] In one embodiment, a housing sealing gasket 44 is fixed to the socket housing protrusion 45 and / or the socket inner housing flange 46 , and the housing sealing gasket 44 connects the socket housing protrusion 45 and the socket inner housing flange 46 .

[0066] Optionally, the housing sealing gasket 44 may be made of a material having certain compressive elasticity. Optionally, the housing sealing gasket 44 may be made of, but not limited to, silicone or rubber.

[0067] Optionally, the socket inner shell 41 and the socket outer shell 42 may be made of, but not limited to, flame-retardant plastic material.

[0068] Specifically, the above arrangement forms the third waterproofing of the socket, preventing external water from entering the socket inner shell 41, and blocking water entering the gap of the sealing gasket 14 outside the socket inner shell 41, so as to prevent water from entering the socket inner shell 41 when the first and second waterproofing fail.

[0069] Specifically, the present invention achieves a good waterproof effect through a triple waterproof structure.

[0070] Working principle of the first waterproof structure: an upper cover plug sealing gasket 11 is fixed around the socket hole 13 of the socket upper cover 12. When the plug is inserted, the upper cover plug sealing gasket 11 fits tightly with the lower wall of the plug body, so that water from the surrounding environment cannot enter the socket hole 13, so that the socket hole 13 of the upper cover plug is in a sealed state.

[0071] The working principle of the second waterproof structure: a protrusion 16 is formed on the inner wall of the sealing pad plug hole 15. The protrusion 16 and the plug terminal or the sealing gasket 21 are squeezed to allow the plug terminal or the sealing gasket 21 to pass through the sealing pad plug hole 15 while the side of the plug or the sealing gasket 21 is tightly fitted with the hole wall, so that external water cannot enter the sealing pad plug hole 15, so as to achieve the sealing of the sealing pad plug hole 15.

[0072] Working principle of the third waterproof structure: a shell sealing gasket 44 is fixed on the socket shell protrusion 45 and / or the socket inner shell flange 46, and the shell sealing gasket 44 connects the socket shell protrusion 45 and the socket inner shell flange 46, and blocks the water entering the gap of the sealing gasket 14 outside the socket inner shell 41, so as to prevent water from entering the socket inner shell 41 when the first waterproof and second waterproof fail.

[0073] The embodiment of the present invention further provides a vehicle, comprising the aforementioned waterproof structure. The aforementioned waterproof structure is used in a vehicle to improve the airtightness and waterproof performance of the vehicle socket, and protect the vehicle socket from being entered by water from the external environment.
