[0038] The charging gun is an important part of the current charging equipment in the new energy vehicle industry. In order to achieve stable locking and unlocking of the charging gun and the external charging interface during the charging process, the charging gun is usually equipped with an electronic lock device to ensure the locking of the charging gun and the external interface. However, in actual use, users often encounter difficulties in pulling out the charging gun. This situation is usually caused by the failure of the electronic lock device to work properly or a malfunction. Therefore, it is necessary to add an emergency unlocking structure to the charging gun. When the electronic lock device cannot be released due to mechanical failure or electronic signal problems, the emergency unlocking structure can be used to unlock the charging gun. The current emergency unlocking operation of the charging gun mostly uses an external slender push rod, a pull wire or a long key hanging on the outside of the charging gun for emergency unlocking. This method is more complicated to assemble and can easily cause scratches on the outside of the vehicle and loss of the unlocking component, affecting the user experience.

[0039] The utility model provides a charging gun. Figures 1 to 8The charging gun includes: a gun housing 1, a mounting cavity 1a is provided in the gun housing 1, and a guide hole 11 is provided on the side wall of the mounting cavity 1a. An unlocking component 2 passes through the guide hole 11, and the unlocking component 2 includes a pressing rod 21, and the pressing rod 21 is provided with a threaded hole 21a along the axial direction. The unlocking component 2 also has a pressing screw 22 that cooperates with the threaded hole 21. An electronic lock component 3 is provided in the mounting cavity 1a, and the electronic lock component 3 includes a motor lock motor 31 and a cam 321, and the cam 321 is rotatably connected to the motor lock motor 31. Press the unlocking component 2 to extend it into the mounting cavity 1a to drive the cam 321 to rotate to the unlocking position.

[0040] In this embodiment, the gun case 1 is used to install, fix and protect the unlocking component 2, the electronic lock component 3 and other components in the charging gun. It is understandable that the gun case 1 can be made of common materials, such as metal materials or hard plastic materials, to facilitate the connection of the charging gun to the external charging socket. The gun case 1 has an installation cavity 1a, and the installation cavity 1a is used to accommodate the electronic lock component 3. A guide hole 11 is provided on the side wall of the installation cavity 1a, and the guide hole 11 is connected to the installation cavity 1a. The unlocking component 2 can be movably arranged in the guide hole 11. It is understandable that the moving direction of the unlocking component 2 is the same as the axial direction of the guide hole 11. One end of the unlocking component 2 passes through the guide hole 11 and extends into the installation cavity 1a, driving the cam 321 to rotate to the unlocking position, so that the charging gun is in an unlockable state. The unlocking assembly 2 is assembled by a pressing rod 21 and a pressing screw 22. The pressing rod 21 and the pressing screw 22 are coaxially arranged with the guide hole 11. The pressing rod 21 can be a columnar, rod-shaped or cylindrical structure. The structural profile and diameter of the pressing rod 21 should match the structural profile and diameter of the guide hole 11, so as to facilitate the movement of the pressing rod 21 along the guide hole 11. The pressing rod 21 is provided with a threaded hole 21a along the axial direction, which is used to cooperate and fix with the pressing screw 22. The pressing screw 22 has a pressing head 221 and a threaded matching part 222. The diameter of the pressing head 221 is larger than the diameter of the guide hole 11, so as to prevent the pressing rod 21 from being pushed into the installation cavity 1a without restriction, thereby limiting the movement range of the unlocking assembly 2. The threaded matching part 222 is threadedly connected with the threaded hole 21a, and the assembly of the pressing rod 21 and the pressing screw 22 can be completed by using an electric screwdriver to lock. This method is simple to assemble, realizes the rapid assembly of the unlocking assembly 2, and improves the assembly efficiency. The electronic lock assembly 3 can also adopt an electronic lock, an electromagnetic lock or a mechanical lock structure. The electronic lock assembly 3 can ensure that the charging gun can be stably locked and unlocked with the external charging interface during the charging process, ensuring the normal charging of the charging gun. The electronic lock assembly 3 includes a motor lock motor 31 and a cam 321. The motor lock motor 31 has a rotating lock core 32. The rotating lock core 32 realizes the functions of unlocking and locking through the drive of the motor lock motor 31, and the structure is simple and stable. The rotating shaft of the motor lock motor 31 is coaxially arranged with the rotating axis of the rotating lock core 32, which has the advantages of small resistance and easy opening and closing. The cam 321 is arranged on the rotating lock core 32. When the motor lock motor 31 drives the rotating lock core 32 to rotate, the rotating lock core 32 synchronously drives the cam 321 to rotate in the installation cavity 1a. A limiting groove 1c corresponding to the cam 321 is arranged in the installation cavity 1a. When the cam 321 rotates to the position where the cam 321 abuts against the limiting groove 1c, the cam 321 cannot rotate further to limit the rotatable range of the cam 321.

[0041] For further information, please refer to Figure 3 and Figure 6A limiting portion 211 is provided on the outer circumferential surface of the pressing rod 21 , and a limiting platform (not shown) is formed on the inner wall of the guide hole 11 . The limiting portion 211 abuts against the limiting platform to prevent the unlocking assembly 2 from being separated from the gun housing 1 .

[0042] Specifically, at least one limiting portion 211 is provided on the outer circumferential surface of the pressing rod 21. The limiting portion 211 can be set as a flat position on the outer circumferential surface extending from the end face close to the pressing screw 22 to the installation cavity 1a. The shape of the flat position can be set as a rectangular or square plane, and the length of the flat position extending along the axial direction of the pressing rod 21 is less than the length of the pressing rod 21. It can be understood that the limiting portion 211 and the outer circumferential surface of the pressing rod 21 form a step surface. At least one limiting platform is provided on the inner wall of the guide hole 11, and the limiting platform is a hole flat position corresponding to the limiting portion 211. It can be understood that the shape and size of the limiting platform are compatible with the limiting portion 211. When the pressing rod 21 is moved into the installation cavity 1a by external pressure, the limiting portion 211 and the limiting platform can be used as guide surfaces to ensure that the pressing rod 21 moves along the correct path. When the pressing rod 21 moves away from the installation cavity, the limiting portion 211 overlaps and aligns with the limiting platform, and the step surface formed by the limiting portion 211 and the outer peripheral surface of the pressing rod 21 abuts against the side wall of the installation cavity 1a, so that the pressing rod 21 cannot move outward indefinitely, limiting the movement range of the unlocking component 2 and preventing the unlocking component 2 from falling off.

[0043] For further information, please refer to Figure 2 and Figure 5 The side wall of the gun housing 1 is concavely provided with a groove 1b for installing the unlocking component 2, and the groove 1b is connected to the guide hole 11.

[0044] Specifically, a groove 1b is concavely arranged on the side wall of the gun housing 1, and the groove 1b is connected with the guide hole 11 and the installation cavity 1a. Preferably, the groove 1b is a cylindrical groove coaxially arranged with the guide hole 11. The unlocking component 2 is movably arranged inside the groove 1b, and the groove 1b is limitedly installed on the unlocking component 2 so that the unlocking component 2 is limited to move within the range of the groove 1b. The diameter of the pressing head 221 of the pressing screw 22 matches the diameter of the groove 1b, and the circumferential side of the pressing head 221 abuts against the side wall of the groove 1b, so that the unlocking component 2 will not shake during the movement and is not easy to lose. The notch of the groove 1b is arranged on the outer wall of the gun housing 1, so that the user can press the unlocking component 2 through the groove 1b to move it into the installation cavity 1a. It can be understood that the depth direction of the groove 1b is the same as the moving direction of the unlocking component 2. When the charging gun is unlocked in an emergency, the user presses the unlocking assembly 2 in the groove 1b, and the unlocking assembly 2 moves inward along the extension direction of the groove 1b. The pressing rod 21 passes through the guide hole 11 to push the cam 321 to rotate, so that the cam 321 rotates to the unlocking position. In this unlocking position, the charging gun is in an unlockable state. When the charging gun is in a locked state, the pressing head 221 is flush with the side wall of the gun housing 1 to prevent scratches on the exterior of the vehicle; the pressing head 221 can also be slightly protruded from the groove 1b to facilitate blind operation by the user in a dark environment. The guide hole 11 is set at the bottom of the groove 1b, connecting the groove 1b with the installation cavity 1a. By using the limiting platform of the guide hole 11 and the limiting portion 211 of the pressing rod 21 to limit the unlocking assembly 2, it is prevented from detaching or slipping from the groove 1b. At the same time, the limiting installation of the unlocking assembly 2 by the groove 1b effectively avoids the loss of the unlocking assembly 2.

[0045] For further information, please refer to Figure 6 , Figure 7 and Figure 8 The pressing rod 21 is provided with an unlocking spring 23 on its outer sleeve. The unlocking spring 23 is arranged in the groove 1b. One end of the unlocking spring 23 abuts against the pressing screw 22, and the other end abuts against the groove 1b.

[0046] It can be understood that the unlocking spring 23 is sleeved on the outside of the pressing rod 21 and is limitedly installed in the groove 1b. The pressing rod 21 is elastically reset by the unlocking spring 23. After the unlocking assembly 2 is assembled into the groove 1b, the circumferential side of the pressing head 221 abuts against the inner wall of the groove 1b, and the outer peripheral surface of the pressing rod 21 located in the groove 1b and the inner wall of the groove 1b, the side of the pressing head 221 facing the installation cavity 1a, and the groove bottom wall of the groove 1b enclose a receiving space, and the unlocking spring 23 is limitedly assembled in the receiving space. One bottom end of the unlocking spring 23 abuts against the groove bottom wall of the groove 1b, and the other end abuts against the side of the pressing head 221 facing the installation cavity 1a. When the emergency unlocking operation is performed on the charging gun, the pressing head 221 is pressed inward, so that the unlocking spring 23 is pressed and compressed, and the pressing rod 21 moves into the installation cavity 1a, pushing the cam 321 to rotate to the unlocking position, so that the charging gun is in an unlockable state. When the pressing force applied to the pressing head 221 is removed, the unlocking spring 23 is elastically reset by the elastic force, and at the same time, the pressing head 221 is elastically reset by the elastic force of the unlocking spring 23, driving the overall structure of the unlocking assembly 2 to be reset. The step surface formed by the limiting portion 211 and the outer peripheral surface of the pressing rod 21 abuts against the side wall of the mounting cavity 1a, so that the pressing rod 21 cannot move outward without restriction, limiting the movement range of the unlocking assembly 2, and preventing the unlocking assembly 2 from detaching from the gun housing 1. The unlocking assembly 2 is restored to the unpressed position by the unlocking spring 23, and at this time, the charging gun can be normally unlocked.

[0047] The utility model proposes an embodiment, please refer to Figure 2 and Figure 6 A lock hook assembly is arranged on the gun housing 1 , and the lock hook assembly comprises: a lock hook body 4 , the lock hook body 4 is integrally provided with a button 41 convexly; and a lock hook cover 5 , the lock hook cover 5 is covered on the outside of the lock hook body 4 .

[0048] Specifically, the lock hook body 4 has a card plate 42, which is integrally arranged with the button 41, and the lock hook cover 5 has a cover body 52 and an integrally arranged, upwardly protruding button cover 51. The bottom of the lock hook cover 5 is recessed with an accommodating cavity, and the lock hook body 4 is placed in the accommodating cavity. The shape of the button cover 51 matches the shape of the button 41. It can be understood that the shape of the button 41 can be set to square, round, oval or other shapes, and the shape of the button cover 51 adapts to the shape setting of the button 41, so that the button cover 51 fits the button 41. Preferably, in this embodiment, the shape of the button 41 is rectangular, and the shape of the button cover 51 is also rectangular, covering the outside of the button 41. When the button cover 51 moves downward due to external pressure, the button 41 is driven to move downward. At the same time, a clamping protrusion 13 is at least partially protruded upward on the side wall of the gun housing 1, and a clamping groove 522 matching the clamping protrusion 13 is at least partially recessed on the peripheral surface of the lock hook cover 5. The bottom end of the side wall of the clamping groove 522 fits with the top end of the side wall of the clamping protrusion 13, so that the lock hook assembly is fixedly connected to the gun housing 1, and the position stability of the lock hook assembly when pressed is ensured.

[0049] For further information, please refer to Figure 3 and Figure 6 A contact portion 411 is provided on one side of the button 41 facing the electronic lock assembly 3. When the charging gun is locked, the contact portion 411 contacts the cam 321, restricting the button 41 from moving.

[0050] Specifically, the button 41 faces the side of the electronic lock assembly 3, and an abutment portion 411 is protruded downward at the corresponding position of the cam 321. When the charging gun is locked, the abutment portion 411 abuts against the cam 321, limiting the button 41 from being pressed downward. Preferably, the end face shape of the abutment portion 411 facing the cam 321 matches the outer contour of the cam 321, so that the abutment portion 411 is more tightly connected to the cam 321, ensuring that the button 41 is in a state where it cannot move downward, thereby enhancing the locking stability of the charging gun. When the charging gun is locked, the cam 321 is in a non-unlocked position. In the non-unlocked position, the cam 321 abuts against the abutment portion 411, limiting the abutment portion 411 from moving downward. At this time, even if the user presses the button cover 51 by mistake, the button 41 cannot be pressed down due to the action of the electronic lock assembly 3, thereby avoiding mis-locking of the charging gun. When the charging gun is unlocked in an emergency, the unlocking component 2 is pressed to push the cam 321 to rotate, so that the electronic lock component 3 is in an unlocked state, and the cam 321 rotates to the unlocked position. In the unlocked position, the cam 321 and the abutment part 411 are staggered from each other, and the pressing of the button 41 is not restricted. At this time, the user presses the button cover 51, and the button cover 51 presses down the button 41, and the button 41 drives the abutment part 411 to move downward, and the cam 321 and the abutment part 411 are staggered, so that the abutment part 411 can move downward smoothly, thereby realizing the unlocking of the charging gun.

[0051] For further information, please refer to Figure 2 and Figure 5 A lock hook spring 6 is provided between the abutting portion 411 and the gun housing 1 , one end of the lock hook spring 6 abuts against the inside of the gun housing 1 , and the other end abuts against the abutting portion 411 .

[0052] Specifically, the lock hook spring 6 is arranged in the installation cavity 1a, between the abutment portion 411 and the gun housing 1, one end of the lock hook spring 6 is elastically connected to the abutment portion 411 of the button 41, and the other end is elastically connected to the inside of the gun housing 1. The arrangement of the lock hook spring 6 can help the button 41 to achieve elastic reset. When the user presses the button 41, the lock hook spring 6 is compressed by the pressure. When the pressure of the button 41 is removed, the button 41 is reset to the place covered by the button cover 51 by the elastic force of the lock hook spring 6. Optionally, the lock hook spring 6 is a compression spring.

[0053] For further information, please refer to Figure 2 and Figure 5 A positioning column 412 is protruding downward from the abutting portion 411 , and the lock hook spring 6 is sleeved on the outside of the positioning column 412 .

[0054] Specifically, the positioning column 412 is arranged at a position where the rear section of the abutment portion 411 faces the installation cavity 1a, the cam 32 and the abutment portion 411 have a contact position, the positioning column 412 is staggered with the contact position, the positioning column 412 can be set as a cylinder, and the lock hook spring 6 is sleeved on the outside of the positioning column 412 to limit and guide the lock hook spring 6 to prevent the lock hook spring 6 from detaching during pressing and elastic resetting.

[0055] For further information, please refer to Figure 2 The lock hook body 4 protrudes downward to have two pivoting parts 43 spaced apart in the left-right direction, and the lock hook assembly also has a rotating shaft 71, through which the two pivoting parts 43 are connected to the gun housing 1. The rotating shaft 71 has a second threaded hole axially opened, and the rotating shaft 71 also has a rotating shaft screw 72 adapted to the second threaded hole.

[0056] Specifically, the lock hook body 4 protrudes downward in front of the button 41 to have two pivoting parts 43 spaced apart in the left-right direction. The left and right side walls of the gun case 1 are provided with two mounting holes 12 at the corresponding positions of the two pivoting parts 43. The two pivoting parts 43 are connected to the gun case 1 through a rotating shaft 71. The rotating shaft 71 passes through the two mounting holes 12 and the two pivoting parts 43, and the left and right sides of the lock hook body 4 are locked to the gun case 1 through a rotating shaft screw 72. When the button 41 moves downward under external force, the lock hook body 4 is driven to rotate around the rotating shaft 71. The electronic lock assembly 3 is located below the button 41. When the electronic lock assembly 3 is in an unlocked state, the cam 321 is in a position to avoid the abutting part 411. At this time, the button 41 can move downward under the action of external force. The end of the card plate 42 away from the button 41 is provided with a hook 44 for engaging the external charging seat. When the charging gun is in the unlocked state, the lock hook spring 6 is compressed by external force, the button 41 is pressed down, the card plate 42 rotates around the shaft 71, and the end of the card plate 42 close to the button 41 is driven to be pressed down, and the end of the card plate 42 away from the button 41 is lifted upward, driving the hook 44 to be lifted upward together, so that the lock hook body 4 is separated from the external charging seat, and the charging gun and the external charging seat are unlocked. At this time, the charging gun can be unplugged from the external charging seat, and the unlocking is convenient and quick. After the charging gun is unlocked, the external force on the button 41 is removed, and the button 41 is elastically reset by the elastic force of the lock hook spring 6, driving the card plate 42 to rotate around the shaft 71, and the hook 44 is reset together.

[0057] For further information, please refer to Figure 2 The lock hook body 4 has a positioning opening 421 in front of the button 41 , and the lock hook cover 5 has a positioning protrusion protruding downward (not shown in the figure), which is matched with the positioning opening 421 , and the positioning protrusion passes downward through the positioning opening 421 and abuts against the motor lock motor 31 .

[0058] Specifically, a positioning opening 421 is provided on the card plate 42, and a positioning protrusion is provided on the lock hook cover 5 to pass through the positioning opening 421. The size of the positioning opening 421 is slightly larger than the end face size of the positioning protrusion, so that the positioning protrusion can pass through the positioning opening 421.

In order to ensure the safety and stability of the locking of the charging gun and the external charging seat during the actual charging process, an electronic lock component 3 is usually provided in the charging gun. When the charging gun and the external charging seat are in a stable charging state, the control device controls the electronic lock component 3 to be in a locked position, at which time the abutment portion 411 abuts against the cam 321, and the button 41 cannot move downward, ensuring that the charging gun is in a correctly locked state. At this time, even if the user presses the button 41 by mistake, the hook portion 44 cannot be lifted upward due to the abutment of the cam 321 against the abutment portion 411, so that the charging gun will not be separated from the external charging seat. At the same time, the electronic lock assembly 3 transmits a feedback signal to the control device, so that the power supply device recognizes that the electronic lock assembly 3 is in the locked position and maintains normal power supply. When charging is completed, the control device stops supplying power, the electronic lock assembly 3 receives the electrical signal, and the cam 321 rotates to the unlocked position. At this time, the button 41 is pressed, and the button 41 is staggered with the cam 321. The button 41 can move downward smoothly, so that the hook 44 is lifted upward, and the charging gun can be separated from the external charging seat. When an abnormal situation occurs during the charging process, causing the electronic lock assembly 3 to be unable to be unlocked normally, manual unlocking can be achieved through the unlocking assembly 2, so that the charging gun can be pulled out to avoid accidents caused by the inability to unlock. When the situation that the unlocking cannot be done normally occurs, the cam 321 is in a locked state, and cooperates with the abutment portion 411 to abut, so that the button 41 cannot be pressed down, and the hook portion 44 at the front end of the lock hook body 4 cannot be lifted. At this time, the emergency unlocking operation should be performed, pressing the unlocking assembly 2 at the groove 1b of the side wall of the gun housing 1, the pressing head 221 is subjected to inward pressing force, the unlocking spring 23 is compressed, the pressing screw 22 drives the pressing rod 21 to pass through the guide hole 11 to move inside the installation cavity 1a, the pressing rod 21 pushes the cam 321 to rotate, so that the cam 321 avoids the position where the abutment portion 411 moves downward, and the lock hook spring 6 is compressed. The button 41 drives the lock hook body 4 to rotate around the rotating shaft 71, so that the hook portion 44 is lifted upward and separated from the external charging seat. At this time, the unlocking is completed, and the charging gun can be smoothly pulled out of the external charging seat. The button 41 is automatically reset by the elastic force under the action of the lock hook spring 6, and the unlocking assembly 2 is automatically reset by the elastic force under the action of the unlocking spring 23, which is convenient to use. The unlocking assembly 2 is connected by the unlocking screw 22 and the pressing rod 21 with threads, and the assembly is simple and convenient. The pressing rod 21 is provided with a limit portion 211 to prevent the unlocking assembly 2 from being separated from the charging gun. Preferably, the unlocking screw 22 and the rotating shaft screw 72 can be assembled with the same type of screws to improve the assembly efficiency of the charging gun.
