[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or it can be in a middle component. When a component is said to be "connected" to another component, it can be directly connected to the other component or it may be in a middle component.

[0033] Unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used in this invention includes any and all combinations of one or more of the associated listed items.

[0034] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0035] This invention provides a waterproof socket, such as Figure 1 As shown, the socket includes a top cover 12, a sealing gasket 21, an elastic element 22, and a housing 43. The top cover 12 and the housing 43 cooperate to form a receiving space, and the sealing gasket 21 and the elastic element 22 are disposed within the receiving space. The top cover 12 is provided with a socket hole 13, which is opposite to the sealing gasket 21. The elastic element 22 is connected to the sealing gasket 21 to apply a pushing force to the sealing gasket 21 and seal the socket hole 13. Optionally, the elastic element 22 is a spring.

[0036] like Figure 1 As shown, by setting the socket cover 12, sealing gasket 21, elastic element 22 and housing 43, the socket cover 12 and housing 43 cooperate to form an accommodating space. The sealing gasket 21 and elastic element 22 are set in the accommodating space. The socket cover 12 is provided with a socket hole 13. The socket hole 13 is opposite to the sealing gasket 21. The elastic element 22 connects to the sealing gasket 21. The elastic element 22 applies a pushing force to the sealing gasket 21 so that the sealing gasket 21 is inserted into the socket hole 13 to seal the socket hole 13, thereby achieving a waterproof effect.

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

[0038] In one embodiment, such as Figure 1 As shown, a top cover plug sealing gasket 11 is fixed around the socket hole 13 of the socket cover 12. When the plug is inserted, the top cover plug sealing gasket 11 fits tightly against the lower wall of the plug body.

[0039] Optionally, the shape of the top cover plug sealing gasket 11 can be a polygon, an oval, or an irregular shape with a central cutout.

[0040] Optionally, the sealing gasket 11 of the top cover plug can be made of a material with certain compressive elasticity. Optionally, the material of the sealing gasket 11 can be, but is not limited to, silicone or rubber.

[0041] Optionally, the top cover plug 12 and sealing gasket 21 may be, but are not limited to, flame-retardant plastic materials.

[0042] Specifically, the above-mentioned design forms the first layer of waterproof structure for the waterproof socket. When there is water in the environment around the socket, it blocks the water from entering the socket 13 of the top cover plug, thus keeping the socket 13 of the top cover plug in a sealed state.

[0043] In one embodiment, such as Figure 3 As shown, the socket cover 12 also includes a sealing gasket 14, one end of which is connected to the housing 43. The socket 13 also includes a sealing gasket plug hole 15, which is positioned opposite to the socket 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 connects 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 sealing gasket 14 can be made of a material with certain compressive elasticity. Specifically, the sealing gasket 14 can be, but is not limited to, silicone or rubber.

[0046] In one embodiment, such as Figure 2 As shown, a protrusion 16 is formed on the inner wall of the sealing gasket plug hole 15. The protrusion 16 is pressed against the plug terminal or sealing gasket 21, so that the plug terminal or sealing gasket 21 can pass through the sealing gasket plug hole 15 while the side of the plug terminal or sealing gasket 21 is tightly fitted with the hole wall to achieve a seal of the sealing gasket plug hole 15.

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

[0048] Specifically, the above-mentioned setup forms a second waterproof structure for the waterproof socket. When external water enters the socket 13, it can be blocked outside the sealing gasket plug hole 15, preventing external water from entering the sealing gasket plug hole 15 and thus sealing the sealing gasket plug hole 15.

[0049] One embodiment, such as Figure 2 As shown, the waterproof socket also includes a conductor 23. The conductor 23 has a clamping part at one end near the socket cover 12. The sealing gasket 21 and the clamping part can slide relative to each other and abut against the plug terminal when the plug terminal is inserted.

[0050] Optionally, the conductor 23 can be a material with conductive properties. Optionally, the conductor 23 can be, but is not limited to, a copper busbar.

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

[0052] One embodiment, such as Figure 2 As shown, the waterproof socket also includes a conductor 23, which is connected to the housing 43. The conductor 23 has a through hole 26 at its bottom, and the elastic element 22 is fixed to the housing 43 through the through hole 26.

[0053] Specifically, the above configuration determines the position of the elastic element 22 and fixes the position of the conductor 23 by limiting the elastic element 22 to the bottom through hole 26 and the housing 43 of the conductor 23.

[0054] One embodiment, such as Figure 4 As shown, the waterproof socket also includes a conductor 23, on which a sealing gasket limiting post 25 is fixed. The sealing gasket 21 has a slotted hole 24, which extends in a second direction from the end of the sealing gasket 21 near the plug. The sealing gasket limiting post 25 extends laterally and is inserted into the slotted hole 24. The sealing gasket 21 can move longitudinally within the restricted range of the slotted hole 24. The second direction is the direction in which the plug terminals are inserted.

[0055] Optionally, the sealing gasket limit post 25 may be, but is not limited to, a flame-retardant plastic material.

[0056] Specifically, the above-mentioned setting restricts the movement position of the sealing gasket 21 to prevent the protrusion 27 from moving too far to the second direction position and damaging the micro switch 31 when the socket is inserted too deeply, and to prevent the sealing gasket 21 from moving too far to the second direction position and damaging the elastic element 22. The second direction is the direction in which the plug terminal is inserted.

[0057] One embodiment, such as Figure 1 As shown, when the plug terminal is pulled out, the elastic element 22 pushes the sealing gasket 21 to move in the first direction; as 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] One embodiment, such as Figure 5 As shown, the waterproof socket also includes a micro switch 31 and a conductor 23. The conductor 23 is connected to the micro switch 31, and the power supply is controlled by opening and closing 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 a second direction, so that the protrusion 27 moves in the second direction to press the micro switch 31, thus opening the circuit. The second direction is the direction in which the plug terminal is inserted.

[0059] Specifically, the above-mentioned configuration forms a circuit switch inside the socket, which opens the circuit when the plug is inserted and disconnects the circuit when the plug is removed, thus preventing accidental contact and reducing the risk of leakage.

[0060] One embodiment, such as Figure 1 As shown, the socket cover 12 also includes a sealing gasket 14, and the socket 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; as 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 socket 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-mentioned design enables the socket to be effectively waterproof both when the plug terminals are unplugged and when the plug terminals are plugged in.

[0062] One embodiment, such as Figure 1 As shown, when the plug terminal is pulled out, the elastic force released by the pressure on the elastic element 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 broken; as Figure 2 As shown, when the plug terminal is inserted, it pushes the sealing gasket 21 to move in the second direction. At this time, the protrusion 27 moves in the second direction, the micro switch 31 is pressed, and the circuit is completed. 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 settings ensure that the circuit is in a closed state when the plug is inserted and in a closed state when the plug is removed, effectively preventing accidental contact.

[0064] One 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. There is a protrusion 45 inside the socket outer shell 42. There is a flange 46 on the outside of the socket inner shell 41. The flange 46 of the socket inner shell overlaps the protrusion 45 of the socket outer shell.

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

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

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

[0068] Specifically, the above-mentioned design forms a third layer of waterproofing for 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 layers of waterproofing fail.

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

[0070] The working principle of the first waterproof structure: The socket cover 12 has a top cover plug sealing gasket 11 fixed around the socket hole 13. When the plug is inserted, the top cover plug sealing gasket 11 is tightly attached to the lower wall of the plug body, so that water from the surrounding environment cannot enter the socket hole 13, thus keeping the socket hole 13 of the top cover plug 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 gasket plug hole 15. The protrusion 16 is pressed against the plug terminal or sealing gasket 21, so that the plug terminal or sealing gasket 21 can pass through the sealing gasket plug hole 15, while the side of the plug or sealing gasket 21 is tightly fitted with the hole wall, so that external water cannot enter the sealing gasket plug hole 15, thereby achieving the sealing of the sealing gasket plug hole 15.

[0072] The working principle of the third waterproof structure: A housing sealing gasket 44 is fixed on the socket outer shell protrusion 45 and / or the socket inner shell flange 46. The housing sealing gasket 44 connects the socket outer shell protrusion 45 and the socket inner shell flange 46, blocking water entering the gap of the sealing gasket 14 from entering the socket inner shell 41, so as to prevent water from entering the socket inner shell 41 when the first and second waterproof layers fail.

[0073] This invention also provides a vehicle including the aforementioned waterproof structure. When used in a vehicle, the aforementioned waterproof structure improves the airtightness and waterproof performance of the vehicle's electrical outlet, protecting it from external water ingress.
