Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually of the same type, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the associated objects before and after.

[0038] It should be understood that "some embodiments" mentioned throughout the specification means that specific features, structures, or characteristics related to the embodiments are included in at least one embodiment of the present invention. Therefore, the "in some embodiments" that appears throughout the specification does not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics can be combined in one or more embodiments in any suitable manner.

[0039] Next, a charging gun locking structure, a charging gun, a charging pile, a charging port locking structure, a vehicle, and a charging gun locking system provided by the present invention will be introduced in detail by listing specific embodiments.

[0040] Figure 1 It is a schematic structural diagram of a charging gun locking structure 1 provided by an embodiment of the present invention.

[0041] See Figure 1 , the charging gun locking structure 1 includes a locking rod 11 and an insertion slot 12. The insertion slot 12 is adapted to receive the lock tongue 31 to limit the detachment of the locking rod 11, and a first drag reduction member 13 is provided at the portion where the locking rod 11 cooperates with the lock tongue 31.

[0042] In the embodiment of the present application, the locking tongue 31 is a component of the charging port structure. Since the locking tongue 31 is adapted to extend into the insertion slot 12 to restrict the detachment of the locking lever 11, after the locking tongue 31 of the charging port structure extends into the insertion slot 12, the locking tongue 31 can restrict the detachment of the locking lever 11, thereby preventing the charging gun locking structure 1 from detaching from the charging port. Therefore, it can effectively prevent the safety risks caused by the separation of the charging gun 100 with large current during charging and the problem of unauthorized unplugging of the gun.

[0043] Next, since a first friction reducing member 13 is provided at the portion where the locking lever 11 and the locking tongue 31 cooperate. When the locking tongue 31 retracts from the insertion slot 12, the friction between the locking tongue 31 and the inner wall of the insertion slot 12 can be reduced, making it easier for the locking tongue 31 to be pulled out from the insertion slot 12, and further making it easier for the charging gun 100 to be pulled out from the charging port. In addition, since the friction between the locking tongue 31 and the inner wall of the insertion slot 12 is reduced, the wear and deformation of the inner wall of the insertion slot 12 and the locking tongue 31 are reduced, that is, the wear and deformation of the internal structure of the charging gun 100 and the locking tongue 31 are reduced. Therefore, the service life of the charging gun 100 and the charging port can be extended.

[0044] It should be noted that the material of the locking tongue 31 can be metal, plastic or glass, or other solid materials with the same function. The embodiment of the present application does not limit this. When its material is metal, the metal can be iron, copper, aluminum or alloy, or other metal materials with the same function. The embodiment of the present application does not limit this.

[0045] Optionally, in some embodiments, refer to Figure 1 and Figure 4 , when the locking lever 11 and the locking tongue 31 are in a locked state, the first friction reducing member 13 and the locking tongue 31 are in point contact.

[0046] Compared with the case where the first friction reducing member 13 and the locking tongue 31 are in surface contact, when the first friction reducing member 13 and the locking tongue 31 are in point contact, the friction between them can be smaller. In this way, when the charging gun 100 is pulled out from the charging port, the locking lever 11 is easier to separate from the locking tongue 31, and further the charging gun 100 is easier to be pulled out from the charging port. In addition, since the friction between the locking tongue 31 and the inner wall of the insertion slot 12 is smaller, the wear and deformation of the inner wall of the insertion slot 12 and the locking tongue 31 are reduced, that is, the wear and deformation of the internal structure of the charging gun 100 and the locking tongue 31 are reduced. Therefore, the service life of the charging gun 100 and the charging port can be further extended.

[0047] Optionally, in some embodiments, refer to Figure 1 and Figure 4, the first drag reducing member 13 is a rolling member. In this way, when the locking rod 11 contacts the lock tongue 31, the friction between the first drag reducing member 13 and the surface of the lock tongue 31 at the matching position of the two is rolling friction. According to conventional physical knowledge, under the same pressure, the rolling friction is less than the sliding friction, so the friction between the first drag reducing member 13 and the lock tongue 31 can be further reduced. In this way, when the charging gun 100 is pulled out of the charging port, the locking rod 11 is more easily separated from the lock tongue 31, thereby making it easier to pull the charging gun 100 out of the charging port. In addition, since the friction between the lock tongue 31 and the inner wall of the plug-in slot 12 is smaller, the wear and deformation of the lock tongue 31 and the inner wall of the plug-in slot 12 can be further reduced, so the service life of the charging gun 100 and the charging port can be further extended.

[0048] Optionally, in some embodiments, see Figure 1 and Figure 4 , the first drag reducing member 13 is a roller.

[0049] Since the roller is a commonly used rolling part, the manufacturing and installation technology is relatively mature and the cost is low. In this way, the stability of the charging gun locking structure 1 can be improved while reducing the friction force, and the manufacturing cost of the charging gun locking structure 1 can also be reduced.

[0050] It should be noted that the above-mentioned rolling element may also be a ball, or other rolling element with the same function, and the embodiments of the present application do not limit this.

[0051] Optionally, in some embodiments, see Figure 1 and Figure 4 The charging gun locking structure 1 includes a button 14, which is fixedly connected to a locking rod 11. When the button 14 is pressed, one end of the locking rod 11 away from the button 14 rises.

[0052] Specifically, the button 14 is located at one end of the locking rod 11 away from the first drag reducing member 13, and a lock hook 15 is provided at the other end of the locking rod 11, and the lock hook 15 can be connected with the lock hook 15 groove of the charging port. The locking rod 11 can rotate around its middle part, and the button 14 and the lock hook 15 are connected in the form of a lever. When the button 14 is pressed, the button 14 drives the lock hook 15 to disengage from the charging port through the lever structure.

[0053] See also Figure 1 , Figure 2 and Figure 4 The embodiment of the present application further discloses a charging gun 100 , which includes any one of the above-mentioned charging gun locking structures 1 .

[0054] Since the insertion slot 12 is adapted to receive the locking tongue 31 therein to restrict the detachment of the locking lever 11, after the locking tongue 31 of the charging port structure extends into the insertion slot 12, the locking tongue 31 can restrict the detachment of the locking lever 11, thereby preventing the charging gun locking structure 1 from detaching from the charging port. Therefore, it can effectively prevent the safety risks caused by the separation of the charging gun 100 with large current during charging and the problem of unauthorized unplugging of the gun.

[0055] Next, since a first friction reducing member 13 is provided at the portion where the locking lever 11 and the locking tongue 31 cooperate. When the locking tongue 31 retracts from the insertion slot 12, the friction between the locking tongue 31 and the inner wall of the insertion slot 12 can be reduced, making it easier for the locking tongue 31 to be pulled out of the insertion slot 12, and thus making it easier for the charging gun 100 to be pulled out of the charging port. In addition, since the friction between the locking tongue 31 and the inner wall of the insertion slot 12 is reduced, the wear and deformation of the locking tongue 31 and the inner wall of the insertion slot 12 are reduced, that is, the wear and deformation of the internal structure of the charging gun 100 and the locking tongue 31 are reduced. Therefore, the service life of the charging gun 100 can be extended.

[0056] Optionally, in some embodiments, refer to Figure 1 , Figure 2 and Figure 4 , the charging gun 100 includes an upper housing 2. Along the first direction ( Figure 2 the Y direction in

[0057] ), the upper housing 2 is spaced apart from the locking lever 11 and encloses to form an insertion slot 12. When the locking lever 11 and the locking tongue 31 in the charging port are in a locked state, at least a part of the locking tongue 31 is received in the insertion slot 12. In the embodiments of the present application, since the upper housing 2 and the locking lever 11 are spaced apart along the first direction and enclose to form the insertion slot 12. In this way, the upper housing 2 can have two functions. On the one hand, it can be used as a housing to protect the internal structure of the charging gun 100. On the other hand, it can be used as a structure for forming the insertion slot 12, which can make the internal structure of the charging gun 100 simpler and is beneficial to reducing the volume of the charging gun 100. Next, since when the locking lever 11 and the locking tongue 31 in the charging port are in a locked state, at least a part of the locking tongue 31 is received in the insertion slot 12. The insertion slot 12 can restrict the movement of the locking tongue 31 in a direction perpendicular to the insertion direction of the locking tongue 31, thereby making the connection between the charging gun locking structure 1 and the charging port more stable. Therefore, the connection between the charging gun 100 and the charging port can be made more stable.

[0058] Optionally, in some embodiments, refer to Figure 1 , Figure 2 and Figure 4 , the upper housing 2 is adapted to cooperate with the locking tongue 31 in the charging port for locking; a second friction reducing member 21 is provided at the portion where the upper housing 2 and the locking tongue 31 cooperate.

[0059] Since a second friction reducing member 21 is provided at the portion where the upper housing 2 mates with the locking tongue 31. In this way, when the locking tongue 31 retracts from the insertion slot 12, the frictional force between the locking tongue 31 and the upper housing 2 can be reduced, making it easier for the locking tongue 31 to be pulled out of the insertion slot 12, and thus making it easier for the charging gun 100 to be pulled out of the charging port. In addition, since the frictional force between the locking tongue 31 and the upper housing 2 is reduced, the wear and deformation of the inner wall of the locking tongue 31 and the insertion slot 12 are reduced, that is, the wear and deformation of the internal structure of the charging gun 100 and the locking tongue 31 are reduced, so the service life of the charging gun 100 and the charging port can be extended. In summary, adding the second friction reducing member 21 on the basis of the first friction reducing member 13 not only makes it easier for the charging gun 100 to be pulled out of the charging port, but also further reduces the wear and deformation of the internal structure of the charging gun 100 and the locking tongue 31, so the service life of the charging gun 100 and the charging port can be further extended.

[0060] Optionally, in some embodiments, referring to Figure 1 , Figure 2 and Figure 4 , when the upper housing 2 and the locking tongue 31 are in a locked state, the second friction reducing member 21 and the locking tongue 31 are in point contact.

[0061] Compared with the case where the first friction reducing member 13 and the upper housing 2 are in surface contact, when the first friction reducing member 13 and the upper housing 2 are in point contact, the frictional force between them can be smaller. In this way, when the charging gun 100 is pulled out of the charging port, the upper housing 2 is more likely to be separated from the locking tongue 31, and thus the charging gun 100 is more likely to be pulled out of the charging port. In addition, since the frictional force between the locking tongue 31 and the upper housing 2 is small, the wear and deformation of the inner wall of the locking tongue 31 and the insertion slot 12 are reduced, that is, the wear and deformation of the internal structure of the charging gun 100 and the locking tongue 31 are reduced, so the service life of the charging gun 100 and the charging port can be further extended.

[0062] Optionally, in some embodiments, referring to Figure 1 , Figure 2 and Figure 4 , the second friction reducing member 21 is a rolling member.

[0063] When the upper housing 2 contacts the locking tongue 31, the frictional force between the second drag reduction member 21 at the mating part and the surface of the locking tongue 31 is rolling friction. According to conventional physical knowledge, under the same pressure, rolling friction is less than sliding friction. Therefore, the frictional force between the second drag reduction member 21 and the locking tongue 31 can be further reduced. In this way, when the charging gun 100 is pulled out from the charging port, the upper housing 2 is more likely to separate from the locking tongue 31, and thus the charging gun 100 is more likely to be pulled out from the charging port. In addition, since the frictional force between the locking tongue 31 and the upper housing 2 is smaller, the wear and deformation of the inner wall of the locking tongue 31 and the insertion slot 12 can be further reduced. Therefore, the service life of the charging gun 100 and the charging port can be further extended.

[0064] It should be noted that, in addition to being rolling members, the first drag reduction member 13 and the second drag reduction member 21 can also be sliding members, and the surface friction coefficients of these sliding members are relatively small. Therefore, the frictional resistance at the contact position can be reduced. In this way, the locking tongue 31 can be more easily inserted into and separated from the insertion slot 12. The wear and deformation of the locking tongue 31 and the insertion slot 12 can also be reduced. In addition, the surface of the sliding member can also be coated with a lubricant or paint to further reduce the friction coefficient, or other methods can be used to reduce the friction coefficient. The embodiments of the present application do not limit this.

[0065] Optionally, in some embodiments, refer to Figure 1 , Figure 2 and Figure 4 , the second drag reduction member 21 is a roller.

[0066] Since the roller is a commonly used rolling member, the manufacturing and installation technologies are relatively mature and the cost is relatively low. In this way, on the basis of reducing the frictional force, the stability of the charging gun locking structure 1 can be improved. In addition, the manufacturing cost of the charging gun locking structure 1 can be further reduced.

[0067] Optionally, in some embodiments, refer to Figure 1 , Figure 2 and Figure 4 , the first drag reduction member 13 and the second drag reduction member 21 are correspondingly arranged along the first direction ( Figure 2 the Y direction in

[0068] ). In this way, when the locking tongue 31 extends into the insertion slot 12, the supporting force applied by the locking lever 11 to the first drag reduction member 13 and the force applied by the upper housing 2 to the second drag reduction member 21 are both along the first direction and on the same straight line. In this way, the locking tongue 31 is subjected to symmetric supporting forces, thereby avoiding bending of the locking tongue 31. Therefore, it is possible to avoid the locking tongue 31 from shifting in position when inserted into the insertion slot 12, so that the performance of the charging gun 100 is more stable.

[0069] It should be noted that the above first direction is perpendicular to the insertion direction of the locking tongue 31.

[0070] See Figure 1 , Figure 2 and Figure 4 , this embodiment of the present application also discloses a charging pile, which includes any one of the above charging guns 100.

[0071] Since the locking tongue 31 is adapted to extend into the insertion slot 12 to restrict the detachment of the locking rod 11, after the locking tongue 31 of the charging port structure extends into the insertion slot 12, the locking tongue 31 can restrict the detachment of the locking rod 11, thereby preventing the charging gun locking structure 1 from detaching from the charging port, so it can effectively prevent the safety risks caused by the separation of the charging gun 100 with large current during charging and the problem of unauthorized unplugging of the gun. When the charging gun 100 is installed on the charging pile, charging with this charging pile is safer and more reliable.

[0072] Next, since a first friction reducing member 13 is provided at the portion where the locking rod 11 cooperates with the locking tongue 31. When the locking tongue 31 retracts from the insertion slot 12, the friction between the locking tongue 31 and the inner wall of the insertion slot 12 can be reduced, making it easier for the locking tongue 31 to be pulled out of the insertion slot 12, and thus making it easier for the charging gun 100 to be pulled out of the charging port. In addition, since the friction between the locking tongue 31 and the inner wall of the insertion slot 12 is reduced, the wear and deformation of the inner wall of the insertion slot 12 are reduced, that is, the wear and deformation of the internal structure of the charging gun 100 and the locking tongue 31 are reduced, so the service life of the charging gun 100 can be extended, that is, the service life of this charging pile can be extended.

[0073] See Figure 1 , Figure 2 and Figure 3 , this embodiment of the present application also discloses a charging port locking structure 3, which includes a locking tongue 31, and the locking tongue 31 is adapted to cooperate with any one of the above charging gun locking structures 1 to lock any one of the above charging guns 100 to the charging port.

[0074] In this embodiment of the present application, the locking tongue 31 of the charging port locking structure 3 can extend into the insertion slot 12 of the charging gun locking structure 1 to restrict the detachment of the locking rod 11, thereby preventing the charging gun locking structure 1 from detaching from the charging port, so it can effectively prevent the safety risks caused by the separation of the charging gun 100 with large current during charging and the problem of unauthorized unplugging of the gun.

[0075] In addition, the locking tongue 31 can abut against a first drag reducing member 13 provided on the locking rod 11. In this way, when the locking tongue 31 retracts from the insertion slot 12, the frictional force between the locking tongue 31 and the inner wall of the insertion slot 12 can be reduced, making it easier for the locking tongue 31 to be pulled out of the insertion slot 12, and further making it easier for the charging gun 100 to be pulled out of the charging port. Since the frictional force between the locking tongue 31 and the inner wall of the insertion slot 12 is reduced, the wear and deformation of the locking tongue 31 and the inner wall of the insertion slot 12 are reduced, so the service life of the charging gun 100 and the charging port can be extended.

[0076] Optionally, in some embodiments, referring to Figure 1 , Figure 2 and Figure 3 , the cross-section of the locking tongue 31 gradually decreases along the direction pointing to the insertion slot 12 during insertion ( Figure 3 the X direction in

[0077] Specifically, the insertion end of the locking tongue 31 is a cone. The cross-section of the cone gradually decreases along the direction pointing to the insertion slot 12 during insertion. In this way, when the locking tongue 31 is inserted into the insertion slot 12, the cone can play a guiding role, making it easier for the locking tongue 31 to be inserted into the insertion slot 12, and further making it easier for the charging gun 100 to be inserted into the charging port. When the locking tongue 31 disengages from the insertion slot 12, the cone can also play a guiding role, making it easier for the locking tongue 31 to separate from the insertion slot 12, and further making it easier for the charging gun 100 to be pulled out of the charging port. Therefore, the user experience can be improved.

[0078] In addition, the charging port locking structure 3 further includes a driving device 32, and the driving device 32 can drive the locking tongue 31 to move. In this way, the movement of the locking tongue 31 is made easier, facilitating the insertion of the locking tongue 31 into the insertion slot 12 or the separation from the insertion slot 12. In addition, the driving device 32 is electrically connected to the button 14. When the button 14 is pressed, the driving device 32 drives the locking tongue 31 to retract, and when the button 14 is reset, the driving device 32 drives the locking tongue 31 to extend.

[0079] It should be noted that the above driving device 32 can be an electronic lock, a mechanical lock, or other types of driving devices 32, and the embodiments of the present application do not limit this.

[0080] Referring to Figure 1 , Figure 2 and Figure 3 , the embodiments of the present application also disclose a vehicle, and the vehicle includes any one of the above charging port locking structures 3.

[0081] In the embodiments of the present application, the vehicle includes the charging port locking structure 3. Since the charging port locking structure 3 includes a locking tongue 31, the locking tongue 31 is adapted to cooperate with any of the above charging gun locking structures 1 to lock any of the above charging guns 100 to the charging port. In this way, the vehicle can cooperate with any of the above charging guns 100 to complete the charging process.

[0082] The locking tongue 31 of the charging port locking structure 3 can extend into the insertion slot 12 of the charging gun locking structure 1 to limit the detachment of the locking rod 11, thereby preventing the charging gun locking structure 1 from detaching from the charging port, and thus effectively preventing the safety risks that may be caused by the separation of the charging gun 100 with large current during charging and the problem of unauthorized unplugging of the gun. In this way, the charging safety of the vehicle is relatively high, which can further improve the user experience.

[0083] In addition, the locking tongue 31 can be in contact with a first drag reduction member 13 provided on the locking rod 11. In this way, when the locking tongue 31 retracts from the insertion slot 12, the friction between the locking tongue 31 and the inner wall of the insertion slot 12 can be reduced, making it easier for the locking tongue 31 to be pulled out of the insertion slot 12, and thus making it easier for the charging gun 100 to be pulled out of the charging port. Since the friction between the locking tongue 31 and the inner wall of the insertion slot 12 is reduced, the wear and deformation of the inner wall of the insertion slot 12 of the locking tongue 31 are reduced, so the service life of the charging port can be extended, and thus the service life of the vehicle is extended.

[0084] It should be noted that the vehicle can be a pure electric vehicle or a hybrid vehicle, and the embodiments of the present application do not limit this. Classified by vehicle type, the vehicle can be a sedan, an SUV, a commercial vehicle or a bus, and the embodiments of the present application do not limit this.

[0085] See Figure 1 、 Figure 3 、 Figure 4 and Figure 5 In addition, the embodiments of the present application also disclose a charging gun locking system 200, which includes any of the above charging gun locking structures 1 and any of the above charging port locking structures 3.

[0086] The charging gun locking structure 1 and the charging port locking structure 3 can cooperate with each other to connect or separate. Specifically, the charging port locking structure 3 includes a locking tongue 31, and the locking tongue 31 is adapted to cooperate with the charging gun locking structure 1 to lock or separate the charging gun 100 from the charging port.

[0087] In addition, the locking tongue 31 can abut against a first drag reduction member 13 provided on the locking lever 11. In this way, when the locking tongue 31 retracts from the insertion slot 12, the frictional force between the locking tongue 31 and the inner wall of the insertion slot 12 can be reduced, making it easier for the locking tongue 31 to be pulled out of the insertion slot 12, and further enabling the charging gun 100 to be easily pulled out of the charging port. Since the frictional force between the locking tongue 31 and the inner wall of the insertion slot 12 is reduced, the wear and deformation between the locking tongue 31 and the inner wall of the insertion slot 12 are reduced, so the service life of the charging gun locking structure 1 and the charging port locking structure 3 can be extended, and thus the service life of the charging gun locking system 200 can be extended.

[0088] Optionally, in some embodiments, referring to Figure 1 , Figure 3 , Figure 4 and Figure 5 , the locking tongue 31 of the charging port locking structure 3 can move relative to the vehicle body assembly. The locking tongue 31 has a first position and a second position. When the locking tongue 31 is in the first position, the charging gun locking structure 1 is locked with the charging port locking structure 3; when the locking tongue 31 is in the second position, the charging gun locking structure 1 is unlocked from the charging port locking structure 3.

[0089] In this way, when it is necessary to use the charging gun locking system 200 to charge the vehicle, operate the charging gun locking system 200 to move the locking tongue 31 to the first position. At this time, the charging gun locking structure 1 is locked with the charging port locking structure 3, and then the charging gun 100 can be connected to the charging port, so the charging process of the vehicle can be completed. When it is necessary to pull out the charging gun 100 from the charging port of the vehicle, operate the charging gun locking system 200 to move the locking tongue 31 to the second position. At this time, the charging gun locking structure 1 is unlocked from the charging port locking structure 3, and then the charging gun 100 can be pulled out of the charging port.

[0090] Finally, it should also be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or terminal device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or terminal device. Without further limitation, an element defined by the phrase "comprising a..." does not exclude the existence of additional identical elements in the process, method, article or terminal device comprising the element.

[0091] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
