[0042] 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.

[0043] The utility model provides a charging gun. Figures 1 to 9 The charging gun includes: a gun housing 1, a mounting cavity 1a is provided in the gun housing 1, a guide hole 11 is provided on the side wall of the mounting cavity 1a, and a plug-in port 12 is provided in the gun housing 1 perpendicular to the guide hole 11. An unlocking assembly 2, the unlocking assembly 2 passes through the guide hole 11, and the unlocking assembly 2 includes an unlocking rod 21, and an annular groove 211 is provided in the middle of the unlocking rod 21. A baffle 22 is inserted into the plug-in port 12, and the baffle is engaged with both ends of the annular groove 211 to limit the movement range of the unlocking rod 21 and prevent the unlocking assembly 2 from being separated from the gun housing 1. An electronic lock assembly 3 is provided in the mounting cavity 1a, and the electronic lock assembly 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 assembly 2 to extend it into the mounting cavity 1a to drive the cam 321 to rotate to the unlocking position.

[0044] In this embodiment, the gun case 1 is used to install, fix and protect the unlocking assembly 2, the electronic lock assembly 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, so that the charging gun can be connected 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 assembly 3. A guide hole 11 is opened on the side wall of the installation cavity 1a, and the guide hole 11 is connected to the installation cavity 1a. The unlocking assembly 2 can be movably arranged in the guide hole 11. It is understandable that the moving direction of the unlocking assembly 2 is the same as the axial direction of the guide hole 11. One end of the unlocking assembly 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 includes an unlocking rod 21, which can be a columnar, rod-shaped or cylindrical structure. The structural profile and diameter size of the unlocking rod 21 should match the structural profile and diameter size of the guide hole 11, so that the unlocking rod 21 can move along the guide hole 11. An annular groove 211 is provided in the middle of the unlocking rod 21. It is understandable that the diameter of the unlocking rod 21 at the annular groove 211 is smaller than the diameter of other parts of the unlocking rod 21. The outer circumferential surface of the annular groove 211 and the outer circumferential surface of other parts of the unlocking rod 21 form a step surface, and both ends of the annular groove 211 have the step surface. An insertion port 12 is provided at the vertical guide hole 11 of the gun housing 1, and a baffle 22 is inserted into the insertion port 12. It is understandable that the insertion port 12 is connected to the guide hole 11, and at least a part of the baffle 22 is located inside the guide hole 11. During the axial movement of the unlocking rod 21 along the guide hole 11, the baffle 22 will engage with the step surface of the unlocking rod 21 in the guide hole 11 to limit the movement of the unlocking rod 21. When the unlocking rod 21 moves into the installation cavity 1a, the step surface of the annular groove 211 away from the installation cavity 1a is engaged with the end surface of the baffle 22 facing away from the installation cavity 1a, limiting the unlocking rod 21 from continuing to move into the installation cavity 1a; when the unlocking rod 21 moves in the direction away from the installation cavity 1a, the step surface of the annular groove 211 close to the installation cavity 1a is engaged with the end surface of the baffle 22 facing the installation cavity 1a, limiting the unlocking rod 21 from continuing to move in the direction away from the installation cavity 1a. In this way, the unlocking rod 21 is prevented from being pushed into the installation cavity 1a without restriction, and the unlocking rod 21 is prevented from being separated from the gun housing 1, limiting the movement range of the unlocking assembly 2. The unlocking rod 21 is integrally arranged and installed inside the gun housing 1 in cooperation with the baffle 22, which is convenient to assemble and has a reliable structure. 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 rotary lock core 32. The rotary lock core 32 realizes the functions of unlocking and locking through the drive of the motor lock motor 31. The structure is simple and stable.The rotating shaft of the motor lock motor 31 is coaxially arranged with the rotating axis of the rotary lock core 32, which has the advantages of small resistance and easy opening and closing. The cam 321 is arranged on the rotary lock core 32. When the motor lock motor 31 drives the rotary lock core 32 to rotate, the rotary 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.

[0045] For further information, please refer to Figure 2 , Figure 5 and Figure 8 The side wall of the gun housing 1 is concavely provided with a groove 1b for installing the unlocking assembly 2, and the groove 1b is connected with the guide hole 11. The plug-in port 12 is provided at a position of the gun housing 1 near the bottom of the groove 1b. The baffle plate 22 is provided with a slot 22a for the unlocking rod 21 to move, and the slot 22a is engaged with the unlocking rod 21 at both ends of the annular groove 211 to limit the movement range of the unlocking rod 21.

[0046] 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 limited to install the unlocking component 2 so that the unlocking component 2 is limited to move within the range of the groove 1b. The notch of the groove 1b is arranged on the outer wall of the gun housing 1, which is convenient for the user to press the unlocking component 2 through the groove 1b to move inside 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 component 2 in the groove 1b, and the unlocking component 2 moves inward along the extension direction of the groove 1b. The unlocking 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, and in this unlocking position, the charging gun is in an unlockable state. Near the bottom of the groove 1b, the gun housing 1 is provided with an insertion port 12 in the vertical guide hole 11, and the insertion port 12 is connected with the guide hole 11. The baffle 22 is inserted in the insertion port 12, and the baffle 22 is at least partially located in the guide hole 11. The baffle 22 is provided with a slot 22a for the unlocking rod 21 to move. It can be understood that the shape and size of the insertion port 12 match the shape and size of the baffle 22, so that the connection between the baffle 22 and the gun housing 1 is more stable and not easy to lose. The slot 22a is connected with the guide hole 11, and at least a part of the slot 22a is arranged in the guide hole 11. During the movement of the unlocking rod 21, the two ends of the annular groove 211 will be engaged with the baffle 22 at the slot 22a. By utilizing the limit fit of the unlocking rod 21 at the two ends of the annular groove 211 and the baffle 22 at the slot 22a, the unlocking assembly 2 is prevented from being separated from or slipping off the groove 1b. At the same time, the limit installation of the unlocking assembly 2 by the groove 1b effectively avoids the loss of the unlocking assembly 2.

[0047] For further information, please refer to Figure 2 and Figure 8 The slot 22 a is a U-shaped slot, and the width of the slot 22 a is greater than or equal to the diameter of the unlocking rod 21 at the annular groove 211 .

[0048] Specifically, the slot 22a is a U-shaped slot having an arc segment, the diameter and shape of which match the unlocking rod 21 at the annular groove 211, and the width of the slot 22a is greater than or equal to the diameter of the unlocking rod 21 at the annular groove 211. Preferably, the arc segment fits the outer circumference of the annular groove 211, so as to guide the unlocking rod 21 to move in the slot 22a, further limit the position of the unlocking rod 21, and make the unlocking rod 21 not shake during the movement, and more stable.

[0049] For further information, please refer to Figure 6 , Figure 7 and Figure 8The end of the unlocking rod 21 away from the installation cavity 1a is provided with a pressing portion 212, a first boss 213 is provided between the pressing portion 212 and the annular groove 211, and the end of the unlocking rod 21 away from the pressing portion 212 is provided with a second boss 214. The width of the slot 22a is smaller than the diameter of the unlocking rod 21 at the first boss 213, and smaller than the diameter of the unlocking rod 21 at the second boss 214.

[0050] It is understandable that a pressing portion 212 is provided at one end of the unlocking rod 21 away from the installation cavity 1a, and the structural profile and diameter size of the pressing portion 212 should match the structural profile and diameter size inside the groove 1b, so as to facilitate the movement of the unlocking rod 21 in the groove 1b. The peripheral side of the pressing portion 211 abuts against the side wall of the groove 1b, so that the unlocking assembly 2 will not shake during the movement and is not easy to lose. It is understandable that the diameter of the pressing portion 212 is larger than the diameter of the guide hole 11, further preventing the unlocking rod 21 from being pushed into the installation cavity 1a, ensuring the stability of the position of the unlocking rod 21. When the charging gun is in a locked state, the pressing portion 211 is flush with the side wall of the gun housing 1 to prevent scratches on the exterior of the vehicle; the pressing portion 211 can also be slightly protruding from the groove 1b to facilitate blind operation by the user in a dark environment. There is a first boss 213 between the pressing portion 212 and the annular groove 211, and a second boss 214 is provided at one end of the unlocking rod 21 away from the pressing portion 212. It can be understood that the diameter of the unlocking rod 21 at the annular groove 211 is smaller than the diameter of the unlocking rod 21 at the first boss 213, the diameter of the unlocking rod 21 at the annular groove 211 is smaller than the diameter of the unlocking rod 21 at the second boss 214, the outer circumferential surface of the annular groove 211 and the outer circumferential surface of the first boss 213 form a step surface at one end of the annular groove 211 close to the pressing portion 212, and the outer circumferential surface of the annular groove 211 and the outer circumferential surface of the second boss 214 form a step surface at one end of the annular groove 211 away from the pressing portion 212. The width of the clamping groove 22a is smaller than the diameter of the unlocking rod 21 at the first boss 213, and is also smaller than the diameter of the unlocking rod 21 at the second boss 214. In the process of the unlocking rod 21 moving axially along the guide hole 11, the unlocking rod 21 moves through the clamping groove 22a, and the baffle 22 is clamped with the step surface of the unlocking rod 21 at the clamping groove 22a to limit the moving range of the unlocking rod 21. When the unlocking rod 21 moves into the installation cavity 1a, the step surface formed by the outer circumference of the annular groove 211 and the outer circumference of the first boss 213 engages with the end surface of the baffle 22 facing away from the installation cavity 1a, limiting the unlocking rod 21 from continuing to move into the installation cavity 1a; when the unlocking rod 21 moves in a direction away from the installation cavity 1a, the step surface formed by the outer circumference of the annular groove 211 and the outer circumference of the second boss 214 engages with the end surface of the baffle 22 facing the installation cavity 1a, limiting the unlocking rod 21 from continuing to move in a direction away from the installation cavity 1a. This prevents the unlocking rod 21 from being pushed inward without limit when moving into the installation cavity 1a, and at the same time prevents the unlocking rod 21 from moving in a direction away from the installation cavity 1a without limit, thereby limiting the moving range of the unlocking assembly 2 and preventing the unlocking assembly 2 from falling off.

[0051] The utility model proposes an embodiment, please refer to Figure 7 , Figure 8 and Fig. 9An unlocking spring 23 is disposed on the outer sleeve of the unlocking rod 21. The unlocking spring 23 is disposed in the groove 1b. One end of the unlocking spring 23 abuts against the pressing portion 212, and the other end abuts against the groove 1b.

[0052] It can be understood that the unlocking spring 23 is sleeved on the outside of the unlocking rod 21 and is limitedly installed in the groove 1b. The unlocking 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 portion 212 abuts against the inner wall of the groove 1b, and the outer peripheral surface of the unlocking rod 21 located in the groove 1b, the inner wall of the groove 1b, the side of the pressing portion 212 facing the installation cavity 1a, and the 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 bottom wall of the groove 1b, and the other end abuts against the side of the pressing portion 212 facing the installation cavity 1a. When the charging gun is subjected to an emergency unlocking operation, the pressing portion 212 is pressed inwardly, so that the unlocking spring 23 is compressed by the pressing force, and the unlocking rod 21 moves toward the inside of the installation cavity 1a, extends into the installation cavity 1a, and pushes 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 part 212 is removed, the unlocking spring 23 is elastically reset by the elastic force, and at the same time, the pressing part 212 is elastically reset by the elastic force of the unlocking spring 23, driving the overall structure of the unlocking assembly 2 to reset. The step surface formed by the second boss 214 and the outer peripheral surface of the annular groove 211 abuts against the baffle 22, so that the unlocking 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.

[0053] The utility model proposes an embodiment, please refer to Figure 2 and Figure 7 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 .

[0054] 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.

[0055] For further information, please refer to Figure 2 , Figure 8 and Fig. 9 A contact portion 411 is provided on the 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.

[0056] 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.

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 part 211 is subjected to inward pressing force, the unlocking spring 23 is compressed, the pressing part 211 drives the unlocking rod 21 to pass through the guide hole 11 to move inside the installation cavity 1a, and the unlocking rod 21 pushes the cam 321 to rotate, so that the cam 321 avoids the position where the abutment part 411 moves downward, and the lock hook spring 6 is compressed, and the button 41 drives the lock hook body 4 to rotate around the rotating shaft 71, so that the hook part 44 is lifted upward and separated from the external charging seat, and the unlocking is completed at this time, and the charging gun can be smoothly pulled out from 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 rod 21 is integrally arranged and is clamped and installed inside the gun housing 1 with the baffle 22, which is simple and convenient to assemble, and at the same time, the moving range of the unlocking assembly 2 is limited, effectively preventing the unlocking assembly 2 from being separated from the charging gun.
