Description

Technical Field

[0001] This utility model relates to the field of charging equipment technology, and in particular to a DC charging gun and a charging pile. Background Technology

[0002] New energy vehicles generally use electricity as their power source and need to be connected to the electric vehicle via a charging gun. Among existing charging solutions, DC charging piles have higher voltage and faster charging speeds compared to AC charging piles.

[0003] However, when a DC charging gun is charging, the button is not locked, making it easy for others or users to accidentally operate it, which can lead to charging interruption and affect charging efficiency. Utility Model Content

[0004] In view of the above problems, this application provides a DC charging gun and a charging pile to solve the technical problem that when the button of the DC charging gun is not locked during charging, it is easy for others or users to operate it accidentally, which leads to charging interruption and affects charging efficiency.

[0005] To achieve the above objectives, in a first aspect, the inventor provides a DC charging gun, comprising:

[0006] The charging gun body includes a housing and a micro switch installed inside the housing;

[0007] The safety assembly includes a protective cover, a connecting pressure plate, a button, an elastic element, and a safety hook. The protective cover is connected to the outer shell and is mounted on the connecting pressure plate and hinged to it. A button is provided at one end of the connecting pressure plate, protruding from the protective cover. An elastic element is installed at the bottom of the button. A safety hook is provided at the other end of the connecting pressure plate.

[0008] The locking assembly includes a locking lever, a rotation drive unit, and a rotating component. The locking lever is installed at the bottom of the connecting pressure plate. The rotation drive unit and the rotating component are installed inside the housing. The rotation drive unit is connected to a micro switch. The output end of the rotation drive unit is connected to the rotating component. The rotating component is located below the locking lever. The rotation drive unit is used to drive the rotating component to rotate. The rotating component cooperates with the locking lever to restrict the button from being pressed down vertically.

[0009] Unlike existing technologies, the technical solution of this application includes a rotation drive unit connected to a micro switch. The micro switch controls the rotation drive unit to rotate according to the charging status of the charging gun. The rotation drive unit then controls the rotation of a rotating component, causing the rotating rod to engage with the locking rod. Specifically, when the charging gun is charging, the rotating component rotates to a designated position to restrict the button from being pressed downwards vertically. When the charging gun is not charging, the rotating component rotates to a designated position to remove the restriction on the button, allowing the button to be used normally. Thus, when the charging gun is charging, it can restrict the button from being pressed downwards vertically, ensuring that the safety hook remains engaged with the car charging dock, preventing accidental operation by others or users, and guaranteeing charging efficiency.

[0010] In one embodiment of this utility model, the rotating component includes a rotating block and a protrusion disposed on the rotating block. The output end of the rotation drive unit is connected to the rotating block. The rotation drive unit is used to drive the rotating component to rotate, and the protrusion is used to lock the rod to abut.

[0011] Thus, by setting a protrusion to abut against the locking lever, the button can be prevented from pressing the connecting plate downwards in the vertical direction. In actual use, when the charging gun is charging, the rotation drive unit controls the rotating block to rotate, so that the protrusion is directly below the locking lever, and the protrusion restricts the locking lever from moving downwards in the vertical direction; when the charging gun is not charging, the rotation drive unit controls the rotating block to return to its original position, and the locking lever can move downwards in the vertical direction normally.

[0012] In one embodiment of this utility model, the rotating block is provided with two or more protrusions evenly distributed around its circumference, and there is a receiving groove between two adjacent protrusions for inserting the locking rod.

[0013] Thus, by evenly distributing two or more protrusions around the circumference of the rotating block, with a receiving groove between adjacent protrusions, the rotation drive unit can rotate in one direction. In actual use, when the charging gun is charging, the rotation drive unit controls the rotating block to rotate, positioning the protrusions directly below the locking rod, thus restricting the locking rod from moving vertically downwards. When the charging gun is not charging, the rotation drive unit again controls the rotating block to rotate, positioning the receiving grooves directly below the locking rod, allowing the locking rod to move normally vertically downwards.

[0014] In one embodiment of this utility model, the bottom surface of the locking rod and the top surface of the protrusion are both arc surfaces.

[0015] In this way, by setting the bottom surface of the locking rod and the top surface of the protrusion to be curved surfaces, the curved surfaces can play a significant buffering role when the locking rod and the protrusion come into contact, thus extending the service life of the locking rod and the protrusion.

[0016] As one embodiment of this utility model, the locking assembly also includes a gasket, and a gasket is installed at the bottom of the locking rod.

[0017] Thus, by installing a shim at the bottom of the locking lever, a good cushioning effect can be achieved, extending the service life of the locking lever and the protrusion. In some embodiments, a shim can also be installed at the top of the protrusion to further enhance the cushioning effect.

[0018] In one embodiment of this utility model, a first limiting block is provided at the bottom of the locking rod, and the rotating part has a first limiting groove. The first limiting groove is U-shaped or C-shaped and is used to accommodate the first limiting block to restrict the locking rod from moving downward in the vertical direction.

[0019] Thus, by cooperating with the first limiting block and the first limiting groove, the locking rod can be restricted from moving downward in the vertical direction, thereby restricting the button from being pressed downward in the vertical direction.

[0020] In one embodiment of this utility model, the bottom of the locking rod has a second limiting groove, and the top of the rotating part is provided with a second limiting block. The cross-section of the second limiting block is L-shaped, and the second limiting groove is used to accommodate the second limiting block to restrict the locking rod from moving downward in the vertical direction.

[0021] Similarly, by cooperating with the second limiting block and the second limiting groove, the locking rod can also be restricted from moving downward in the vertical direction, thereby restricting the button from being pressed downward in the vertical direction.

[0022] As one embodiment of this utility model, the micro switch has first threaded holes on both sides, and the outer casing has a second threaded hole at the corresponding position. The second threaded hole and the first threaded hole are connected by fasteners.

[0023] In this way, the micro switch is mounted on the housing using fasteners, which facilitates the installation, removal, or maintenance of the micro switch. These fasteners can be bolts, screws, studs, etc.

[0024] As one embodiment of this utility model, the charging gun body also includes a charging head and a protective cover. The charging head is installed at one end of the outer shell, and the protective cover is fitted onto the charging head.

[0025] In this way, the charging head can be protected by setting a protective cover.

[0026] To achieve the above objectives, in a second aspect, the inventors provide a charging station, including a DC charging gun as described above.

[0027] Unlike existing technologies, the DC charging gun in this application has a locking component, which can prevent others from pulling out the DC charging gun while the user is using the charging station, thus affecting the user's normal use.

[0028] The above description of the utility model is merely an overview of the technical solution of this application.

[0051] According to some embodiments of this application, this embodiment relates to a charging pile, including a DC charging gun 100.

[0052] The DC charging gun 100 of this application has a locking component 3, which can prevent others from pulling out the DC charging gun 100 while the user is using the charging station, thus affecting the user's normal use.

[0053] According to some embodiments of this application, please refer to Figures 1 to 9 This embodiment also relates to a DC charging gun 100, including a charging gun body 1, a safety assembly 2, and a locking assembly 3; the charging gun body 1 includes a housing 11 and a micro switch 12 installed inside the housing 11; the safety assembly 2 includes a protective cover 21, a connecting pressure plate 22, a button 23, an elastic element 24, and a safety hook 25. The protective cover 21 is connected to the housing 11, and is mounted on and hinged to the connecting pressure plate 22. A button 23 is provided at one end of the connecting pressure plate 22, protruding from the protective cover 21. An elastic element 24 is installed at the bottom of the button 23. The other end of the pressure plate 22 is provided with a safety hook head 25; the locking assembly 3 includes a locking rod 31, a rotation drive unit 32 and a rotating component 33. The locking rod 31 is installed at the bottom of the pressure plate 22, and the rotation drive unit 32 and the rotating component 33 are installed inside the housing 11. The rotation drive unit 32 is connected to the micro switch 12, and the output end of the rotation drive unit 32 is connected to the rotating component 33. The rotating component 33 is located below the locking rod 31. The rotation drive unit 32 is used to drive the rotating component 33 to rotate. The rotating component 33 cooperates with the locking rod 31 to limit the button 23 from being pressed down in the vertical direction Y.

[0054] One end of the housing 11 is connected to the charging head 13, and the other end of the housing 11 is used to connect the cable, which in turn connects to the charging pile body. Various components are installed inside the housing 11, especially the micro switch 12.

[0055] The protective cover 21 is connected to the outer shell 11. One end of the protective cover 21 is hinged to the connecting pressure plate 22 via a hinge rod 26. The connecting pressure plate 22 moves relative to the outer shell 11 in the vertical direction Y. Therefore, when the button 23 on the connecting pressure plate 22 is pressed, the connecting pressure plate 22 rotates around the hinge rod 26, causing the connecting pressure plate 22 to move upward in the vertical direction Y, thereby raising the safety hook head 25. In actual use, the safety hook head 25 is raised first, and then the charging head 13 is connected to the car's charging socket. After the connection is completed, the button 23 is released (at this time, the elastic element 24 plays a good buffering and restoring role), causing the safety hook head 25 to engage with the car's charging socket. The elastic element 24 is elastic, capable of elastically contracting under pressure and returning to its initial shape when the pressure is removed. The elastic element 24 can be made of metallic elastic materials such as metal springs, or non-metallic elastic materials such as rubber and silicone.

[0056] The rotation drive unit 32 can be a motor or a motor, wherein the motor can rotate forward or in reverse. The rotating component 33 has a locked state and an unlocked state. In the locked state, the button 23 is restricted from being pressed down in the vertical direction Y. In the unlocked state, the restriction on the button 23 is lifted, allowing the button 23 to be pressed down normally in the vertical direction Y.

[0057] The technical solution of this application includes a rotation drive unit 32 connected to a micro switch 12. The micro switch 12 controls the rotation drive unit 32 to rotate according to the charging status of the charging gun. The rotation drive unit 32 then controls the rotation of a rotating component 33, causing the rotating rod to engage with the locking rod 31. Specifically, when the charging gun is charging, the rotating component 33 rotates to a designated position to restrict the button 23 from being pressed downwards in the vertical direction Y. When the charging gun is not charging, the rotating component 33 rotates to a designated position to remove the restriction on the button 23, allowing the button 23 to be used normally. Thus, when the charging gun is charging, it can restrict the button 23 from being pressed downwards in the vertical direction Y, ensuring that the safety hook 25 remains engaged with the car charging socket, preventing accidental operation by others or users, and guaranteeing charging efficiency.

[0058] According to some embodiments of this application, optionally, such as Figure 5 As shown, the rotating component 33 includes a rotating block 331 and a protrusion 332 disposed on the rotating block 331. The output end of the rotation drive unit 32 is connected to the rotating block 331. The rotation drive unit 32 is used to drive the rotating component 33 to rotate, and the protrusion 332 is used to lock the rod 31 to abut.

[0059] Thus, by setting the protrusion 332 to abut against the locking lever 31, the button 23 can be restricted from pressing the connecting pressure plate 22 downward in the vertical direction Y. In actual use, when the charging gun is in the charging state, the rotating part 33 is in the locked state, and the rotation drive unit 32 controls the rotating block 331 to rotate, so that the protrusion 332 is directly below the locking lever 31, and the protrusion 332 restricts the locking lever 31 from moving downward in the vertical direction Y; when the charging gun is not in the charging state, the rotating part 33 is in the unlocked state, and the rotation drive unit 32 then controls the rotating block 331 to return to its original state, and the locking lever 31 can move downward in the vertical direction Y normally.

[0060] According to some embodiments of this application, optionally, such as Figure 6 As shown, the rotating block 331 has two or more protrusions 332 evenly distributed around its circumference, and there is a receiving groove between two adjacent protrusions 332 for the locking rod 31 to be inserted.

[0061] Thus, by evenly distributing two or more protrusions 332 around the circumference of the rotating block 331, and having a receiving groove between adjacent protrusions 332, the rotation drive unit 32 can rotate in one direction (clockwise or counterclockwise). In actual use, when the charging gun is charging, the rotating component 33 is in a locked state, and the rotation drive unit 32 controls the rotating block 331 to rotate, so that the protrusions 332 are directly below the locking rod 31, and the protrusions 332 restrict the locking rod 31 from moving downward in the vertical direction Y; when the charging gun is not charging, the rotating component 33 is in an unlocked state, and the rotation drive unit 32 again controls the rotating block 331 to rotate, so that the receiving groove is directly below the locking rod 31, and the locking rod 31 can move downward in the vertical direction Y normally.

[0062] According to some embodiments of this application, optionally, the bottom surface of the locking rod 31 and the top surface of the protrusion 332 are both arc surfaces.

[0063] Thus, by setting the bottom surface of the locking rod 31 and the top surface of the protrusion 332 to be arc surfaces, the arc surfaces can play a significant buffering role when the locking rod 31 and the protrusion 332 come into contact, thereby extending the service life of the locking rod 31 and the protrusion 332.

[0064] According to some embodiments of this application, optionally, such as Figure 5 As shown, the locking assembly 3 also includes a washer 34, which is installed at the bottom of the locking lever 31.

[0065] Thus, by installing a pad 34 at the bottom of the locking lever 31, a good cushioning effect can be achieved, extending the service life of the locking lever 31 and the protrusion 332. In some embodiments, a pad 34 can also be installed at the top of the protrusion 332 to further enhance the cushioning effect.

[0066] According to some embodiments of this application, optionally, such as Figure 7 As shown, a first limiting block 35 is provided at the bottom of the locking rod 31, and the rotating member 33 has a first limiting groove 333. The first limiting groove 333 is U-shaped or C-shaped. The first limiting groove 333 is used to accommodate the first limiting block 35 to restrict the locking rod 31 from moving downward in the vertical direction Y.

[0067] Thus, by cooperating with the first limiting block 35 and the first limiting groove 333, the locking rod 31 can be restricted from moving downward in the vertical direction Y, thereby restricting the button 23 from being pressed downward in the vertical direction Y.

[0068] According to some embodiments of this application, optionally, such as Figure 8As shown, the bottom of the locking rod 31 has a second limiting groove 311, and the top of the rotating member 33 is provided with a second limiting block 36. The cross-section of the second limiting block 36 is L-shaped, and the second limiting groove 311 is used to accommodate the second limiting block 36 to restrict the locking rod 31 from moving downward in the vertical direction Y.

[0069] Similarly, by cooperating with the second limiting block 36 and the second limiting groove 311, the locking rod 31 can also be restricted from moving downward in the vertical direction Y, thereby restricting the button 23 from being pressed downward in the vertical direction Y.

[0070] According to some embodiments of this application, optionally, such as Figure 9 As shown, the micro switch 12 has first threaded holes 121 on both sides, and the housing 11 has a second threaded hole at the corresponding position. The second threaded hole and the first threaded hole 121 are connected by fasteners.

[0071] Thus, the micro switch 12 is mounted on the housing 11 using fasteners, which facilitates the installation, disassembly, or maintenance of the micro switch 12. The fasteners can be bolts, screws, studs, etc.

[0072] According to some embodiments of this application, optionally, such as Figure 1 and Figure 2 As shown, the charging gun body 1 also includes a charging head 13 and a protective cover 14. The charging head 13 is installed at one end of the outer shell 11, and the protective cover 14 is fitted onto the charging head 13.

[0073] Thus, the charging head 13 can be protected by setting the protective cover 14.

For example, in the claims, any of the claimed embodiments can be used in any combination.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
