[0056] Through the above - mentioned drawings, specific embodiments of the present application have been shown, and there will be more detailed descriptions hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0057] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0058] As shown in the background art, in the prior art, when a sudden power outage or other special situations occur during the charging process of the charging gun, the charging gun may still be in a locked state and cannot be pulled out.

[0059] The emergency unlocking device in the prior art for this problem is to set an unlocking button inside the charging gun and an unlocking hole on the charging gun. For some charging guns, an unlocking tool matching the unlocking hole needs to pass through the unlocking hole to press the unlocking button to achieve unlocking. For some other charging guns, there is no configured matching unlocking tool, and the user of the charging gun needs to find a slender bar - shaped tool, such as a wire, and insert the wire into the unlocking hole to press the unlocking button to achieve unlocking.

[0060] However, for the above - mentioned unlocking methods, whether using an unlocking tool or other bar - shaped tools, unlocking needs to be achieved by relying on external objects. The user may have problems such as losing the unlocking tool or not being able to find a bar - shaped tool of the appropriate size. At this time, the charging gun cannot be unlocked, and the operation is rather inconvenient.

[0061] In view of the above technical problems, the embodiment of the present application provides an unlocking mechanism and a charging gun, wherein the unlocking mechanism includes a locking assembly and an unlocking assembly, wherein the locking assembly includes a lock hook and a slider, wherein the slider restricts the rotation of the lock hook during the charging process of the charging gun, thereby locking the charging gun on the charging socket, and the sliding slider can release its restriction on the lock hook, thereby releasing the lock of the charging gun, and when an emergency such as a power outage occurs, the slider cannot slide by itself, so an unlocking assembly is required to push the slider; the unlocking assembly includes a mounting seat, a reset member, and an unlocking pin, wherein the mounting seat is fixed on the housing of the charging gun, and the unlocking pin is mounted on the charging gun through the mounting seat and is slidably connected to the mounting seat, and when an emergency occurs, the unlocking pin is pushed to contact the slider and slide the slider, thereby releasing the restriction on the lock hook, rotating the lock hook, and completing the unlocking, and the reset member restores the unlocking pin to its original position, so that when the unlocking assembly is used to unlock again, the unlocking pin can be directly pushed to unlock. In this way, when the charging gun cannot be pulled out, the unlocking can be completed by simply pushing the unlocking pin on the charging gun, without the aid of other external objects, and the operation is simple and convenient.

[0062] The following specific embodiments are used to describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings:

[0063] It should be noted that the unlocking mechanism provided in the embodiment of the present application can be applied to various charging guns.

[0064] See also Figure 1 , Figure 2 , Figure 3 and Figure 14 As shown, the unlocking mechanism of the embodiment of the present application is used for a charging gun, and includes a locking assembly 100 and an unlocking assembly 200; the locking assembly 100 includes a locking hook 110 and a slider 120; the unlocking assembly 200 includes a mounting seat 210, a reset member 220 and an unlocking pin 230; the locking hook 110 is used to be rotatably connected to the charging gun, and the slider 120 is used to be slidably connected to the charging gun, and the slider 120 is configured to limit the rotation of the locking hook 110 so that the locking assembly 100 locks the charging gun on the charging socket; the mounting seat 210 is used to connect to the charging gun, and the unlocking pin 230 is configured to slide relative to the mounting seat 210 and push the slider 120 to rotate the locking hook 110 to unlock the charging gun; the reset member 220 is installed in the mounting seat 210, and the reset member 220 is configured to drive the unlocking pin 230 to slide away from the slider 120.

[0065] In the present application, the locking assembly 100 is used to lock the charging gun on the charging socket. There is an automatic control unit in the charging gun. During the charging process of the charging gun, the automatic control unit can control the slider 120 to slide to the bottom of the lock hook 110, so that the slider 120 limits the rotation of the lock hook 110, and the lock hook 110 locks the charging gun on the charging socket. After charging is completed, the automatic control unit controls the slider 120 to slide away from the bottom of the lock hook 110, and the charging gun can be unlocked by rotating the lock hook 110. However, if there is an emergency such as a power outage during the charging process, the automatic control unit cannot work normally, the slider 120 is always located under the lock hook 110, and unlocking cannot be achieved. Therefore, an unlocking assembly 200 is set to manually control the unlocking of the charging gun.

[0066] Furthermore, the unlocking assembly 200 includes a mounting seat 210, a reset member 220 and an unlocking pin 230. The unlocking assembly 200 is fixed on the housing of the charging gun through the mounting seat 210. The unlocking pin 230 is slidably connected with the mounting seat 210. The unlocking pin 230 passes through the mounting seat 210 and contacts the slider 120. The user of the charging gun only needs to push the unlocking pin 230, and the slider 120 inside the charging gun is pushed by the unlocking pin 230, so that the slider 120 slides away from the bottom of the lock hook 110, and the lock pin can be rotated to complete the unlocking of the charging gun. After the unlocking is completed, the reset member 220 pushes the unlocking pin 230 to return to its original position. On the one hand, it can prevent the unlocking pin 230 from hindering the sliding of the slider 120 when the charging gun is used again, affecting the locking assembly 100 to lock the charging gun. On the other hand, it is convenient for the user of the charging gun to directly unlock the unlocking pin 230 to improve the unlocking efficiency.

[0067] Among them, the unlocking pin 230 can be set to partially expose the charging gun, so that the user can unlock by directly pressing the unlocking pin 230, which is easy to operate. The specific structure of this application embodiment is not limited, and the unlocking pin 230 can be directly pushed without the help of external objects. The reset member 220 can be set inside the charging gun, and the specific structure of this application embodiment is not limited. For example, the reset member 220 is a spring. When an external force is applied to the unlocking pin 230 and the unlocking pin 230 pushes the slider 120, the spring is compressed. After unlocking is completed, the unlocking pin 230 is no longer pushed, and the spring elastic force pushes the unlocking pin 230 to reset.

[0068] Therefore, by setting up an unlocking mechanism, when an emergency occurs during the charging process and the charging gun cannot be pulled out, the user of the charging gun can directly push the unlocking pin 230 on the charging gun to achieve manual unlocking without the help of other external objects. It is easy to operate and has strong applicability.

[0069] In some possible implementations, see Figure 1 , Figure 3 and Figures 5 to 9As shown in the figure, the mounting base 210 of the embodiment of the present application includes a first clamping portion 211, a first sliding portion 212, and a first stopping portion 213; the first clamping portion 211 is used for clamping with the charging gun, the first clamping portion 211 is located at one end of the first sliding portion 212, and the first stopping portion 213 is located at the other end of the first sliding portion 212; a sliding groove 2121 is formed on the first sliding portion 212, a first through hole 2111 is formed on the first clamping portion 211, a second through hole is formed on the first stopping portion 213, and both the first through hole 2111 and the second through hole communicate with the sliding groove 2121.

[0070] In a specific implementation, the mounting base 210 is fixed to the charging gun through the first clamping portion 211. A sliding groove 2121 is formed on the first sliding portion 212. The unlocking pin 230 passes through the first through hole 2111 and is slidably connected to the sliding groove 2121. The sliding groove 2121 can limit the sliding path of the unlocking pin 230, avoiding the problem that the unlocking pin 230 deviates from the track and cannot accurately push the slider 120. In addition, a first stopping portion 213 is provided at the end of the first sliding portion 212 away from the first clamping portion 211. The first stopping portion 213 can prevent the reset member 220 and the unlocking pin 230 from falling off. At the same time, one end of the reset member 220 is connected to the first stopping portion 213, and the other end is connected to the unlocking pin 230, so that when the unlocking pin 230 is pushed, the reset member 220 is compressed.

[0071] In some implementable ways, referring to Figure 1 、 Figure 2 、 Figure 4 and Figure 1 As shown in FIG. 0, the unlocking assembly 200 of the embodiment of the present application further includes a button 240; one end of the unlocking pin 230 is connected to the button 240, and the other end of the unlocking pin 230 sequentially passes through the first through hole 2111, the sliding groove 2121, and the second through hole to push the slider 120; the button 240 is clamped with the first clamping portion 211.

[0072] In some embodiments, a button 240 is provided at one end of the unlocking pin 230 that exposes the charging gun housing. When manual unlocking is required, the user only needs to press the button 240 to cause the unlocking pin 230 to slide relative to the mounting base 210 and push the slider 120. The button 240 can be integrally formed with the unlocking pin 230, or the button 240 can be separately provided and connected to the unlocking pin 230 by bonding or other means. The embodiments of the present application do not impose any restrictions on this. The button 240 is arranged to be engaged with the first engaging portion 211, and the button 240 is arranged such that an external force needs to be applied to it to slide relative to the first engaging portion 211 towards the slider 120, which can play a role in limiting the unlocking pin 230. On the one hand, it can prevent the unlocking pin 230 from sliding out of the charging gun, and the loss of the unlocking pin 230 affects unlocking. On the other hand, it can prevent the unlocking pin 230 from sliding inwards during charging to push the slider 120 and cause the charging gun to be accidentally unlocked, ensuring safety during the charging process.

[0073] Among them, the button 240 can be arranged to be embedded in the first through hole 2111, or can be arranged to slightly protrude from the first through hole 2111 for the user to press. The embodiments of the present application do not impose any restrictions on this, and the user can directly press the button 240 without the aid of other tools.

[0074] In some feasible ways, referring to Figure 1 、 Figure 3 、 Figure 5 and Figure 6 As shown, the reset member 220 in the embodiments of the present application is a spring; the spring is sleeved on the unlocking pin 230, and the spring is located in the chute 2121. One end of the spring is connected to the button 240, and the other end of the spring is connected to the first stopping portion 213.

[0075] It can be understood that when the reset member 220 is arranged as a spring, when the user presses the button 240 and the unlocking pin 230 slides towards the slider 120, the distance between the button 240 and the first stopping portion 213 is shortened, and the spring is compressed. When the user no longer presses the button 240, the elastic force of the spring pushes the button 240 to drive the unlocking pin 230 to slide away from the slider 120, so that the unlocking pin 230 is reset.

[0076] Among them, the specific connection methods of the two ends of the spring with the button 240 and the first stopping portion 213 are not restricted by the embodiments of the present application. Exemplarily, the two ends of the spring are in contact with both the button 240 and the first stopping portion 213. When the button 240 is pressed, the spring is compressed under the pressure of the button 240. Or the two ends of the spring can also be bonded to at least one of the button 240 and the first stopping portion 213, which can play a role in limiting the spring to prevent it from shifting.

[0077] In some feasible ways, referring to Figure 2 、Figure 7 , Figure 8 , Figure 9 and Figure 1 As shown in FIG. 4, the clamping portion 211 of the embodiment of the present application further includes a first limiting portion 2112, and the first limiting portion 2112 is used to be clamped with the limiting groove 11 on the charging gun.

[0078] It should be noted that, when the mounting base 210 is integrally cylindrical and the first clamping portion 211 is circular, there may be a problem that the mounting base 210 rotates relative to the charging gun, resulting in the loosening or even falling off of the mounting base 210 when the first clamping portion 211 is clamped with the charging gun. Therefore, the first limiting portion 2112 is provided on the side of the first clamping portion 211, and the first limiting portion 2112 is clamped with the limiting groove 11 on the charging gun, which can prevent the mounting base 210 from rotating relative to the charging gun and ensure the stability of the connection between the mounting base 210 and the charging gun.

[0079] Wherein, the shape of the first limiting portion 2112 can be set to a water droplet shape or other irregular shapes to ensure the stability of the mounting base 210. The specific shape of the first limiting portion 2112 is not limited in the present application, as long as it can limit the rotation of the mounting base 210.

[0080] In some implementable ways, referring to Figure 1 , Figure 3 and Figure 1 0 to Figure 12 As shown in FIG., the button 240 of the embodiment of the present application further includes a pressing portion 241, at least one first elastic portion 242 and at least one second clamping portion 243; the first elastic portion 242 corresponds to the second clamping portion 243 one by one, the pressing portion 241 is located at one end of the first elastic portion 242, the second clamping portion 243 is located at the other end of the first elastic portion 242, and the second clamping portion 243 is configured to pass through the first through hole 2111 and be clamped with the first clamping portion 211.

[0081] In specific implementation, in order to prevent the unlocking pin 230 from falling off the mounting base 210, the first elastic portion 242 of the button 240 is clamped with the first clamping portion 211 of the mounting base 210. Among them, the first elastic portion 242 is arranged on the periphery of the pressing portion 241, and the number of the first elastic portion 242 and the second clamping portion 243 can be adjusted according to the sizes of the button 240 and the first through hole 2111, which is not limited in the embodiment of the present application. The second clamping portion 243 can be set to a wedge shape. When assembling the unlocking pin 230 and the button 240, the unlocking pin 230 and the button 240 are passed through the first clamping portion 211 until the second clamping portion 243 is clamped with the first clamping portion 211.

[0082] In addition, a first elastic part 242 is arranged on the button 240. When the unlocking pin 230 is damaged and needs to be replaced, only by pressing the first elastic part 242 can the second clamping part 243 be driven to move so as to disengage from the first clamping part 211. Then, the unlocking pin 230 can be pulled outwards through the button 240, without disassembling the whole unlocking component 200. The operation is convenient and is conducive to saving the maintenance cost.

[0083] It can be understood that the pressing part 241, the first elastic part 242 and the second clamping part 243 can be integrally formed, or can be connected and manufactured in other ways. The embodiments of the present application do not limit this, as long as the button 240 can be stably clamped with the mounting seat 210.

[0084] In some realizable ways, referring to Figure 3 , Figure 6 , Figure 8 , Figure 9 and Figure 1 As shown in FIGS. 4, at least one second elastic part 214 extending towards the direction of the first stopping part 213 is formed on the first limiting part 2112 of the embodiment of the present application. A third clamping part 215 is formed at the end of each second elastic part 214. The third clamping part 215 is used to pass through the mounting hole (not shown in the figure) of the charging gun and be clamped with the charging gun.

[0085] In some embodiments, the mounting seat 210 is clamped with the charging gun through the second elastic part 214. The second elastic part 214 and the third clamping part 215 can be set to have the same structure as the first elastic part 242 and the second clamping part 243. The structures of the first elastic part 242 and the second clamping part 243 have been described in detail in the above embodiments and will not be elaborated here. Setting the second elastic part 214 can ensure the stable connection between the mounting seat 210 and the charging gun, and prevent the unlocking component 200 from slipping off the charging gun. At the same time, when the unlocking component 200 is damaged, only by pressing the second elastic part 214 to disengage the third clamping part 215 from the charging gun, the whole unlocking component 200 can be pulled out from the mounting hole, and a new unlocking component 200 can be replaced and continue to be used without disassembling the charging gun. The operation is convenient and effectively saves the replacement cost of the unlocking component 200.

[0086] Further, the first clamping portion 211, the first sliding portion 212, the first stopping portion 213, the first limiting portion 2112, the second elastic portion 214 and the third clamping portion 215 can be set as an integrally formed structure, so that the mounting seat 210 forms a whole, reducing the difficulty of manufacturing the mounting seat 210. At the same time, it is beneficial to realize the modularization of the unlocking component 200, facilitating the disassembly of the mounting seat 210, improving the installation and replacement efficiency of the unlocking component 200. Also, according to the manufacturing requirements, at least one of the first clamping portion 211, the first sliding portion 212, the first stopping portion 213, the first limiting portion 2112, the second elastic portion 214 and the third clamping portion 215 can be separately set and connected to other parts by bonding or other means to improve the flexibility of the unlocking component 200. The specific connection manner of each part of the mounting seat 210 in the embodiments of the present application is not limited, as long as the unlocking component 200 can be stably installed on the charging gun.

[0087] In some implementable ways, referring to Figure 1 、 Figure 3 、 Figure 1 3 and Figure 14 As shown, the locking hook 110 of the embodiments of the present application includes a locking portion 111 and a second limiting portion 112; the slider 120 includes a second sliding portion 121 and a second stopping portion 122; the locking portion 111 is used to lock the charging gun on the charging socket; the second sliding portion 121 is used to slidably connect with the charging gun; the second stopping portion 122 is configured to abut against the second limiting portion 112 to limit the rotation of the locking portion 111 relative to the charging gun.

[0088] It can be understood that the locking hook 110 is rotatably connected to the charging gun, and the locking portion 111 and the second limiting portion 112 are respectively located at both ends of the rotating shaft. When the second stopping portion 122 is located below the second limiting portion 112 and abuts against the second limiting portion 112, the locking hook 110 cannot rotate, so that the charging gun is locked on the charging socket through the locking portion 111. When the second sliding portion 121 drives the second stopping portion 122 to slide, causing the second stopping portion 122 to disconnect from the second limiting portion 112, the restriction of the second stopping portion 122 on the locking portion 111 is released. By pressing the second limiting portion 112 or relying on the gravity of the second limiting portion 112 itself, the locking portion 111 can rotate relative to the charging gun, and the locking portion 111 is lifted to unlock the charging gun from the charging socket. Among them, the shapes of the second limiting portion 112 and the second stopping portion 122 are not limited in the embodiments of the present application, as long as the rotation of the locking portion 111 can be effectively restricted.

[0089] Among them, the locking part 111 and the second limiting part 112 can be integrally arranged, or the second limiting part 112 can be set as a separate structure and fixed to the locking part 111 by means such as welding. The specific connection method between the locking part 111 and the second limiting part 112 is not limited in the embodiments of the present application. Similarly, the connection method between the second sliding part 121 and the second stopping part 122 is also not limited in the embodiments of the present application, as long as the rotation of the locking hook 110 can be effectively restricted. Exemplarily, the second sliding part 121 and the second stopping part 122 are integrally formed.

[0090] See Figure 1 Figures 3 and Figure 1 4, the embodiments of the present application also provide a charging gun, including a charging gun body 10 and any one of the above unlocking mechanisms provided on the charging gun body 10.

[0091] Among them, the structure and working principle of the unlocking mechanism have been described in detail in the above embodiments, and will not be elaborated here one by one.

[0092] In the embodiments of the present application, the unlocking mechanism is detachably arranged on the charging gun body 10. When an emergency occurs during the charging process, only by pressing the button 240 on the unlocking mechanism, the charging gun body 10 can be pulled out to achieve unlocking, without the need to use other tools, which is convenient to operate and has strong applicability.

[0093] In some implementable ways, see Figure 1 Figures 3 and Figure 1 4, an installation hole and a limiting groove 11 are formed on the charging gun body 10 of the embodiments of the present application; the installation hole is used to install the unlocking component 200 of the unlocking mechanism, and the limiting groove 11 is used to be clamped with the limiting part of the unlocking component 200.

[0094] In some embodiments, an installation hole is formed on the charging gun body 10, and the unlocking component 200 is clamped with the installation hole. When the unlocking component 200 is damaged, the unlocking component 200 can be directly disassembled from the installation hole, and a new unlocking component 200 can be replaced, effectively saving the replacement cost and improving the maintenance efficiency. In addition, a limiting groove 11 needs to be formed on the side of the installation hole, and the shape of the limiting groove 11 matches that of the limiting part of the unlocking component 200. The limiting groove 11 is clamped with the limiting part, which can prevent the unlocking component 200 from rotating and improve the connection stability between the unlocking component 200 and the charging gun body 10.

[0095] In summary, the unlocking mechanism of the embodiment of the present application includes a locking component 100 and an unlocking component 200. The locking hook 110 of the locking component 100 is rotatably connected to the charging gun. When the slider 120 is located below the locking hook 110 to restrict the rotation of the locking hook 110, the charging gun is locked on the charging socket. The unlocking component 200 is fixed to the charging gun through the mounting seat 210. The unlocking pin 230 is slidably connected to the mounting seat 210. Pushing the unlocking pin 230 can make the unlocking pin 230 slide relative to the mounting seat 210, thereby pushing the slider 120 to slide to release the restriction on the locking hook 110 and rotating the locking hook 110 to unlock the charging gun. After unlocking, the reset member 220 resets the unlocking pin 230 for use when unlocking again, and at the same time prevents the unlocking pin 230 from affecting the rotation of the locking hook 110 when the charging gun is used again, thereby affecting the locking of the charging gun. Thus, when the charging gun cannot be pulled out suddenly in the embodiment of the present application, the user only needs to push the unlocking pin 230 provided on the charging gun to complete the unlocking, without the need to rely on other external objects, which is convenient to operate and has strong applicability.
