[0043] An embodiment of the present application provides an automatic control locking device for a charging gun, and an automatic control locking device for a charging gun includes:

[0044] case;

[0045] The charging mechanism comprises a pressing component and a locking hook, wherein the pressing component is arranged on and extends out of the housing, the pressing component contacts the locking hook and can drive the locking hook to move in a vertical direction, so as to lock the charging gun to prevent the charging gun from falling out during charging;

[0046] The locking mechanism includes a locking assembly and a contact switch, wherein the locking assembly is arranged on and extends out of the shell, and when viewed downward in the vertical direction, the lock hook covers the locking assembly, and is used to prevent the lock hook from lifting when the vehicle is charging; the contact switch is arranged on one side of the locking assembly, and is used to separate the locking assembly from the contact switch after the vehicle is charged, and the contact switch controls the movement of the pressing assembly.

[0047] The above-mentioned charging gun automatically controls the locking device through the cooperation of the pressing device, the lock hook, the locking assembly and the contact switch, so that when the lock hook is inserted into the new energy vehicle and the charging protocol is passed, the locking mechanism is controlled to lock the lock hook to prevent the damage to the vehicle and people caused by pulling out the lock hook during the charging process. After charging is completed, the contact switch controls the pressing assembly to lift the lock hook through the separation of the locking assembly and the contact switch, thereby achieving the purpose of fully automatic locking and unlocking of the new energy vehicle.

[0048] Some embodiments of the present application 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.

[0049] See also Figure 1-Figure 12The embodiment of the present application provides a charging gun automatic control locking device 100, including a housing 10, a charging mechanism 20 and a locking mechanism 30. Specifically, the charging mechanism 20 includes a pressing component 21 and a lock hook 22, wherein the pressing component 21 is arranged on and extends out of the housing 10, the pressing component 21 contacts the lock hook 22, and can drive the lock hook 22 to move in a vertical direction, so as to lock the charging gun to prevent the charging gun from falling out during charging. The locking mechanism 30 includes a locking component 31 and a contact switch 32, wherein the locking component 31 is arranged on and extends out of the housing 10, and when viewed downward in a vertical direction, the lock hook 22 covers the locking component 31, so as to prevent the lock hook 22 from lifting when the vehicle is charged; the contact switch 32 is arranged on one side of the locking component 31, so as to separate the locking component 31 from the contact switch 32 after the vehicle is charged, and the contact switch 32 controls the movement of the pressing component 21.

[0050] In a specific embodiment, the device can automatically control the connection status of the charging gun and the new energy vehicle charging seat 200 through the integrated charging mechanism 20. This means that when charging starts, the device can automatically lock the charging gun to ensure the stability of the charging process; after charging is completed, the device can automatically release the charging gun to facilitate the user to disconnect. This automated control reduces the need for manual operation and improves the convenience and efficiency of the charging process.

[0051] Furthermore, the design of the locking mechanism 30 provides a safety guarantee to prevent the charging gun from being accidentally pulled out due to external force or other reasons during the charging process. This not only protects the charging device and the charging port of the vehicle from damage, but also reduces the electrical safety risks that may be caused by poor contact.

[0052] Furthermore, the contact switch 32 in the device can intelligently identify the charging status according to the position of the locking assembly 31. Its function is that after charging is completed, the device can automatically release the charging gun, further improving the user experience and operational convenience.

[0053] Furthermore, the device reduces problems caused by human error (such as prematurely pulling out the charging gun or improperly connecting the charging gun) such as charging interruption, equipment damage or safety accidents by automatically controlling the locking and releasing of the charging gun.

[0054] See also Figure 1-Figure 4In a specific embodiment, the lock hook 22 includes a charging buckle portion 221 and a connecting portion 222 disposed on the charging buckle portion 221, and the connecting portion 222 has a pressing groove 222a extending through it along its thickness direction. The pressing assembly 21 includes a first motor 211 and a pressing member 212, wherein the first motor 211 is disposed in the housing 10, and one end of the pressing member 212 is fixed to the driving shaft of the first motor 211, and the other end extends out and contacts the pressing groove 222a, so as to drive the pressing member 212 to press the connecting portion 222 downward when the first motor 211 is running.

[0055] In one specific embodiment, the pressing member 212 is substantially a semi-cylindrical structure.

[0056] It should be noted that the lock hook 22 includes a charging snap-fit ​​portion 221 and a connecting portion 222. The charging snap-fit ​​portion 221 is the portion of the charging gun that is inserted into the new energy vehicle for charging. Preferably, the charging snap-fit ​​portion 221 is a hook structure that is used to extend into and snap into the charging seat 200 of the new energy vehicle for transmitting electrical energy. The connecting portion 222 is an extension of the charging snap-fit ​​portion 221, and is provided with a pressing groove 222a along the thickness direction. In this embodiment, the pressing groove 222a cooperates with the pressing component 21 to control the movement of the lock hook 22.

[0057] Furthermore, the pressing assembly 21 includes a first motor 211 and a pressing member 212, wherein the first motor 211 is installed inside the housing 10. One end of the pressing member 212 is fixed to the driving shaft of the first motor 211, and the other end extends out of the housing 10 and can contact the pressing groove 222a of the lock hook 22. The above scheme enables the pressing member 212 to move downward and press the connecting portion 222 when the first motor 211 is running, and this movement is achieved by entering the pressing groove 222a.

[0058] In a specific embodiment, the connecting portion 222 is roughly an annular structure, the pressing groove 222a is a through groove in the middle of the connecting portion 222, and the contact surface between the pressing member 212 and the pressing groove 222a is an arc surface with the same curvature. When the pressing member 212 moves in the pressing groove 222a, the pressing member 212 moves in a circular motion along the inner circular surface.

[0059] Furthermore, when the charging gun needs to be released, the first motor 211 is powered for a period of time. Its operation causes the drive shaft and the pressing member 212 fixed thereon to move downward. The pressing member 212 then enters and presses the pressing groove 222a of the connecting portion 222. This action can drive the lock hook 22 to move along a predetermined path (usually in the vertical direction). Therefore, after charging is completed, the pressing member 212 moves to the bottom of the pressing groove 222a, thereby tilting the lock hook 22 and pulling the charging gun out of the new energy vehicle.

[0060] In a specific embodiment, the pressing member 212 can only move in two positions, namely, the highest point and the lowest point in the vertical direction. Specifically, before charging and during charging, the pressing member 212 is located at the highest point, at which time the lock hook 22 is engaged in the charging seat 200 of the new energy vehicle. When charging is completed, the pressing member 212 is driven by the first motor 211 to move along the inner wall of the pressing groove 222a to the lowest point, thereby lifting the lock hook 22 to disengage the lock hook 22 from the charging seat 200 and completing the removal operation of the charging head.

[0061] Preferably, the locking device also includes a second elastic member 60, preferably a spring. Specifically, the second elastic member 60 is provided on the hook and the inner wall of the charging gun. Before charging, due to the pressure of the second elastic member 60, the charging buckle 221 is pressed downward to be parallel. Preferably, the charging buckle 221 is roughly a buckle structure, which has an inclined surface. When the charging gun is inserted into the car, the head of the charging buckle 221 contacts the charging seat 200, and squeezes the second elastic member 60 open and enters the charging seat 200 under the action of pressure, and is pressed into the charging seat 200 under the pressure of the second elastic member 60, so as to realize the connection between the charging gun and the charging seat 200 and charge.

[0062] Please refer to Figure 4 In a specific embodiment, the pressing member 212 includes a first rotating portion 2121, a first supporting portion 2122 and a pressing portion 2123 which are sequentially arranged outwardly along the first motor 211. The first rotating portion 2121 is fixed on the driving shaft of the first motor 211, and the pressing portion 2123 extends out of the housing 10 and contacts the pressing groove 222a.

[0063] It should be noted that the pressing member 212 includes a first rotating portion 2121, a first supporting portion 2122 and a pressing portion 2123. The first rotating portion 2121 is fixed to the driving shaft of the first motor 211, so that the pressing member 212 can move with the rotation of the motor. The above scheme ensures that the pressing member 212 can accurately rotate according to the rotation direction and speed of the motor.

[0064] Furthermore, the first support portion 2122 is located between the first rotating portion 2121 and the pressing portion 2123, and serves as a structural element connecting the two portions. Its design should ensure sufficient strength to support the pressing action, and should also maintain a certain degree of flexibility to adapt to different operating conditions.

[0065] When the above solution is in operation, when the first motor 211 is running, it drives the first rotating part 2121 fixed on its driving shaft to rotate, thereby driving the entire pressing member 212 (including the first supporting part 2122 and the pressing part 2123) to move along the motor axis. Therefore, during the rotation of the pressing member 212, the connecting part 222 is squeezed, thereby realizing the flipping of the lock hook 22, and realizing the separation of the charging gun from the charging base 200.

[0066] It should be noted that, in a specific embodiment, the lock hook 22 is generally a long plate-like structure, and preferably, the lock hook 22 further includes a round shaft 224 disposed between the charging buckle portion 221 and the connecting portion 222. Specifically, the round shaft 224 is rotatably connected to the inner wall of the charging gun, and when the pressing member 212 presses the connecting portion 222, the round shaft 224 serves as a fulcrum, thereby tilting the charging buckle portion 221 to detach from the charging seat 200.

[0067] In summary, the above scheme enables the first motor 211 and the pressing member 212 to convert the power of rotation into the power of up and down movement, thereby realizing precise control of the locking state of the charging gun. This not only improves the automation and safety of the charging process, but also reduces the need for manual operation and potential errors. By precisely controlling the movement of the pressing member 212, it is possible to ensure that the charging gun maintains a stable and reliable connection with the electric vehicle during the charging process, thereby improving charging efficiency and user experience.

[0068] See also Figure 8 , Fig.10 and Fig.12 In a specific embodiment, the cross-sectional areas of the first support portion 2122 and the pressing groove 222a are both circular. In the vertical direction, the center height of the first support portion 2122 is lower than the center height of the pressing groove 222a, so that after the vehicle is charged, the first motor 211 drives the pressing member 212 to rotate, so as to press the lock hook 22 downward in the vertical direction.

[0069] It should be noted that the first support portion 2122 and the pressing groove 222a are both designed with a circular cross-section. This design is conducive to achieving smooth contact and rotation, reducing friction and wear that may occur during operation. The circular design also helps to improve the strength and durability of the overall structure.

[0070] Furthermore, the center height of the first support portion 2122 is set to be lower than the center height of the pressing groove 222a. This height difference design makes it possible for the pressing member 212 to rotate when the first motor 211 drives the pressing member 212 to rotate, because the center height of the first support portion 2122 is lower than the height of the pressing groove 222a, when the pressing groove 222a rotates to the lowest point in the vertical direction, the pressing portion 2123 can squeeze the pressing groove 222a downward, thereby pushing the pressing groove 222a to move downward in the vertical direction, thereby applying a vertical downward force to the connecting portion 222, thereby tilting the charging buckle portion 221.

[0071] Furthermore, when the charging gun is unplugged, in order to prevent the first motor 211 from having excessive output and causing the pressing piece 212 to run one circle along the pressing groove 222a, thereby causing the charging buckle 221 to detach from the charging seat 200 and then snap back into the charging seat 200 under the action of the second elastic member 60, the pressing piece 212 also includes a first limiting portion 2124 arranged around the pressing portion 2123, and the shell 10 is provided with a first limiting groove 11 arranged corresponding to the first limiting portion 2124, which is used to limit the position of the pressing piece 212.

[0072] It should be noted that the pressing member 212 includes a first limiting portion 2124 surrounding the pressing portion 2123, which is a design enhancement for ensuring accurate control of the pressing member 212 in its motion trajectory. The existence of the first limiting portion 2124 provides a physical boundary for limiting the movement range of the pressing member 212 to ensure that it operates in a predetermined path and range.

[0073] In one specific embodiment, the pressing portion 2123 can rotate by 180°.

[0074] See also Figure 1-Figure 4 The locking hook 22 further includes a pressing portion 223 , which is disposed on the end surface of the locking hook 22 away from the connecting portion 222 , and is used for being pressed by a staff member.

[0075] It should be noted that the squeezing portion 223 is located on the lock hook 22. This layout takes into account the convenience and safety of user operation and ensures that when performing manual operation (such as pressing the squeezing portion 223 to unlock or adjust the position of the lock hook 22), the user's hand will not touch the part that may cause injury.

[0076] Furthermore, by providing the pressing portion 223 , when the automatic locking device of the charging gun fails, the charging buckle portion 221 can be lifted by manually pressing the pressing portion 223 , thereby increasing its applicability.

[0077] See also Figure 1-Figure 6The locking assembly 31 includes a second motor 311 and a locking member 312 arranged on the driving shaft of the second motor 311; the locking member 312 includes a second rotating portion 3121, a second supporting portion 3122 and a locking portion 3123 which are sequentially arranged outward from the driving shaft of the second motor 311, the second rotating portion 3121 is fixed on the driving shaft of the second motor 311, and the locking portion 3123 extends out of the housing 10 and is located below the lock hook 22, so as to stop the lock hook 22 from moving during the charging process of the vehicle.

[0078] It should be noted that the second motor 311 provides a power source for driving the action of the locking assembly 31. The function of the second motor 311 is to ensure that the locking member 312 can be precisely controlled to start or stop the locking action as needed. The locking member 312 is arranged outward from the drive shaft of the second motor 311 in sequence, and includes a second rotating portion 3121, a second supporting portion 3122 and a locking portion 3123. Among them, the second rotating portion 3121 is fixed to the drive shaft of the second motor 311, and is responsible for converting the rotational power of the motor into the action of the locking member 312. The second supporting portion 3122, as a structural element connecting the second rotating portion 3121 and the locking portion 3123, provides the necessary support and stability to ensure that the locking portion 3123 can accurately perform its function. The locking portion 3123 extends out of the housing 10 and is located below the lock hook 22. Its main function is to stop the movement of the lock hook 22 during the charging process of the vehicle to ensure that the connection between the charging gun and the vehicle will not be accidentally disconnected due to external force or other factors.

[0079] Specifically, when the vehicle starts charging, the second motor 311 is activated, driving the locking portion 3123 of the locking member 312 to extend and be located under the lock hook 22. The locking portion 3123 at this position effectively prevents the lock hook 22 from moving up and down, thereby locking the charging gun and ensuring the stability and safety of the charging process. After the charging process is completed, the second motor 311 can reverse or stop, so that the locking portion 3123 is withdrawn, the lock hook 22 is released, and the charging gun is allowed to be safely removed.

[0080] In summary, by locking the lock hook 22 during the charging process, the charging gun is prevented from accidentally falling off, thereby ensuring the safety and reliability of the charging process. The automatic control of the locking mechanism 30 greatly reduces the need for manual operation and improves the convenience and efficiency of operation. The use of the second motor 311 allows the locking action to be controlled very accurately, ensuring the response speed and accuracy of the locking mechanism 30.

[0081] In a specific embodiment, the cross-sectional area of ​​the second rotating portion 3121 is an eccentric circle, and the contact switch 32 is disposed on one side of the second rotating portion 3121 so that the second rotating portion 3121 contacts the contact switch 32 when the locking portion 3123 rotates to abut against the locking hook 22 .

[0082] It should be noted that the second rotating part 3121 is in the shape of an eccentric circle, which means that the center of its cross section is not located at the geometric center. This design makes it possible for its outer edge to pass through the fixed point at uneven distances when the second motor 311 drives the rotating part to rotate.

[0083] Furthermore, the contact switch 32 is placed on one side of the second rotating portion 3121 , and the position is precisely calculated to ensure that when the locking portion 3123 rotates to a specific position, ie, abuts against the locking hook 22 , the eccentric circle can touch and activate the contact switch 32 .

[0084] Furthermore, when the locking portion 3123 needs to lock or release the lock hook 22, the second motor 311 is started to drive the second rotating portion 3121 (eccentric circle) to rotate. Due to its eccentric design, the outer periphery of the rotating portion will produce a changing radial distance during the rotation process.

[0085] When the locking part 3123 rotates to the correct position to hold the lock hook 22 in place, a part of the eccentric circle (the point farthest from the center of the circle) contacts the contact switch 32, triggering the switch. At this time, the car is in the charging state. When the eccentric circle rotates and disengages from the contact switch 32, it means that the car is out of the charging state, and the locking part 3123 is disengaged from the lock hook 22, and the lock hook 22 can rotate freely.

[0086] In summary, through the coordinated use of the eccentric circle and the contact switch 32, the system can very accurately control and monitor the position of the locking portion 3123, ensuring that the lock hook 22 is reliably locked during the charging process. The above makes the operation of the locking mechanism 30 not only rely on mechanical action, but also includes the feedback of electronic signals, which improves the intelligent level of operation and helps the system automation management and fault detection. It ensures the stability and safety of the charging gun during the charging process and prevents accidental falling off due to the failure of the lock hook 22 to lock properly.

[0087] See also Figure 1-Figure 3 The lock hook 22 is provided with an opening 22a facing the locking portion 3123, and the locking mechanism 30 further includes an unlocking mechanism 40. The unlocking mechanism 40 includes a first elastic member 41 and an unlocking member 42, the unlocking member 42 includes a sliding portion 421 and an unlocking portion 422 provided on the sliding portion 421, a sliding hole 22b is passed through the lock hook 22, and the sliding portion 421 extends into the sliding hole 22b, and two ends of the first elastic member 41 are respectively abutted against the lock hook 22 and the sliding portion 421, and the sliding portion 421 is provided facing the locking portion 3123.

[0088] It should be noted that the unlocking mechanism 40 includes an unlocking member 42 and a first elastic member 41. The unlocking member 42 includes a sliding portion 421 and an unlocking portion 422. The sliding portion 421 extends into a sliding hole 22b pre-set on the lock hook 22, so that the unlocking member 42 can slide inside the lock hook 22. The unlocking portion 422 is arranged on the sliding portion 421, corresponding to the locking portion 3123, and is used to directly push or pull the locking portion 3123 to achieve the unlocking action. The two ends of the first elastic member 41 are respectively abutted on the lock hook 22 and the sliding portion 421, providing the necessary elastic force to support the return position of the unlocking member 42 or provide power during the unlocking process.

[0089] Furthermore, when the automatic function is damaged and the lock hook 22 needs to be manually pressed to disengage the charging gun, the unlocking mechanism 40 directly acts on the locking portion 3123 through the sliding action of the unlocking member 42. The sliding portion 421 moves in the sliding hole 22b in the lock hook 22, driving the unlocking portion 422 to push or pull the locking portion 3123, thereby releasing the locked state.

[0090] During this process, the first elastic member 41 ensures that the unlocking member 42 can automatically return to the initial position after the unlocking action is completed, so as to be ready for the next locking or unlocking action.

[0091] Furthermore, the above allows the charging gun to be unlocked quickly and safely in an emergency or after charging is completed, which improves the convenience and safety of use. By directly acting on the locking portion 3123 through a physical mechanism, the unlocking process does not rely on complex electronic control, thereby improving the reliability and durability of the system.

[0092] Furthermore, the use of the first elastic member 41 ensures that the unlocking mechanism 40 can automatically return to the starting position after completing the unlocking action, thereby reducing the maintenance requirements and increasing the service life of the device.

[0093] It should be noted that in order to prevent the locking assembly 31 from over-rotating and causing locking errors, the locking member 312 also includes a second limiting portion provided on the locking portion 3123, and the shell 10 has a second limiting groove 12 arranged corresponding to the second limiting portion, so that the locking member 312 only rotates a corresponding angle.

[0094] In order to monitor the normal operation of the locking device when the charging gun is separated, the locking device further includes a pressing switch 50 , which is disposed on the lower surface of the lock hook 22 and is used to receive and transmit a pressing signal of the lock hook 22 when the lock hook 22 is pressed down.

[0095] It should be noted that the push-down switch 50 is set on the lower surface of the lock hook 22. This position selection ensures that the push-down switch 50 can be directly triggered when the lock hook 22 performs a push-down action (ie, in the locking or unlocking process).

[0096] Furthermore, the main function of the push switch 50 is to receive and transmit a signal when the lock hook 22 is pressed down. This signal indicates that the lock hook 22 has been correctly pressed down, thereby confirming that the physical interaction between the charging gun and the locking device is performed as expected.

[0097] Furthermore, in the process of locking or unlocking the charging gun, the lock hook 22 will perform a downward pressing action. When the lock hook 22 is pressed downward to a certain extent, its lower surface will contact and activate the downward pressing switch 50.

[0098] After activation, the push switch 50 will send an electronic signal, which can be transmitted to the control system or monitoring unit to confirm that the pressing action of the lock hook 22 has been completed, and then confirm the locking or release status of the charging gun.

[0099] By monitoring the depressed state of the lock hook 22, the charging gun can be ensured to be correctly locked or released, thereby enhancing the safety and reliability of the entire system. The depressed switch 50 provides a real-time monitoring mechanism that can provide instant feedback on the locked state, help maintain the normal operation of the system, and promptly discover and solve possible problems. In the event of a fault or abnormal situation, the signal of the depressed switch 50 can serve as an important reference for diagnosing the problem, simplifying the fault detection and repair process.

[0100] The above-mentioned charging gun automatically controls the locking device 100 through the cooperation of the pressing device, the lock hook 22, the locking assembly 31 and the contact switch 32, so that when the lock hook 22 is inserted into the new energy vehicle and the charging protocol is passed, the locking mechanism 30 is controlled to lock the lock hook 22 to prevent the damage to the vehicle and people caused by pulling out the lock hook 22 during the charging process. After charging is completed, the contact switch 32 controls the pressing assembly 21 to lift the lock hook 22 through the separation of the locking assembly 31 and the contact switch 32, thereby achieving the purpose of fully automatic locking and unlocking of the new energy vehicle.

[0101] The above is only an implementation method of the present application. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present application, but these improvements are within the scope of protection of the present application.
