The driving device 10 drives the first transmission gear 21 and the two output gears 22 to rotate reciprocatingly at the same time, and the threaded hole 223 of the output gear 22 drives the locking rod 30 to reciprocate on a predetermined moving path.

[0037] Pure electric vehicles among new energy vehicles use batteries to provide electrical energy to the motor, driving the motor to operate and thus propel the vehicle forward. The rechargeable batteries of pure electric vehicles mainly include lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries, and lithium-ion batteries. These batteries can provide power for electric vehicles. At the same time, pure electric vehicles also use batteries to store electrical energy to drive the motor and allow the vehicle to operate normally. The batteries of pure electric vehicles are mainly charged by new energy vehicle charging guns. In existing charging technologies, when a charging seat is distributed with multiple charging interfaces, for example, a DC charging interface and an AC charging interface are distributed at the same time, different charging guns can be used for charging. The current technical solutions all use multiple drive devices 10 to respectively control the locking connection between multiple charging interfaces and the charging gun. Each drive device 10 drives the corresponding locking rod 30 to lock the charging gun to the corresponding charging seat for charging. There are problems such as the large number of parts in the drive device 10 and high manufacturing costs. Therefore, the field of new energy vehicle technology urgently needs an electronic lock that can synchronously control multiple locking rods 30. One driving device 10 can be used to simultaneously control multiple locking rods 30 to lock and connect charging guns, overcome the defects of the existing technology, and solve the problems of the large number of parts of the driving device 10, high manufacturing cost, and low locking strength of a single locking rod 30.

[0038] The present invention only requires one driving device 10. The driving device 10 drives a transmission gear to rotate, thereby driving the two output gears 22 to rotate back and forth at the same time. The threaded hole 223 on each output gear 22 drives its corresponding locking rod 30 to reciprocate on a predetermined moving path. This solution realizes that the same driving device 10 can drive the two locking rods 30 to extend or retract at the same time, so that the electronic lock can lock the DC charging gun and the AC charging gun at the same time, or one driving device 10 drives one locking rod 30 to extend while the other locking rod 30 retracts synchronously, locking the charging gun that needs to be locked according to user needs, ensuring charging safety and ease of use. The present design has a structure in which the screw 31 connected to the locking rod 30 and the threaded hole 223 of the output gear 22 are threadedly connected. The structure is simple, compact and reliable, reduces the design space of the charging stand, and also reduces the manufacturing cost of the electronic lock.

[0039] In some embodiments, as Figure 1 As shown, the driving device 10 includes a driver 11 and an output shaft 12 . The output shaft 12 is coaxially connected to the first transmission gear 21 and drives the first transmission gear 21 to rotate.

[0040] The driver 11 starts to drive the output shaft 12 to rotate, the rotation of the output shaft 12 drives the first transmission gear 21 to rotate, and the rotation of the first transmission gear 21 drives the two output gears 22 to rotate synchronously.

[0041] In some embodiments, as Figure 2 As shown, the driving device 10 includes a driver 11, an output shaft 12 and a driving gear 13. The first transmission gear 21 includes a driving wheel 211 and a driven wheel 212 that are coaxially connected. The driving wheel 211 is engaged with the driving gear 13, and the driven wheel 212 is engaged with the two output gears 22 at the same time.

[0042] The driver 11 starts to drive the output shaft 12 to rotate, the output shaft 12 rotates and drives the driving gear 13 to rotate, the driving gear 13 rotates and drives the driving wheel 211 to rotate, the driven wheel 212 rotates synchronously with the driving wheel 211 and drives the two output gears 22 to rotate synchronously.

[0043] In some embodiments, as Figure 3 As shown, the transmission mechanism 20 further includes at least one second transmission gear 23 , which is meshed with and transmission-connected to the driving gear 13 and the first transmission gear 21 respectively.

[0044] The multi-stage gear transmission structure with the second transmission gear 23 has a high transmission ratio, stable transmission, and high load capacity, making the reciprocating motion of the locking rod 30 more labor-saving and stable.

[0045] In some embodiments, as Figure 4As shown, one of the external threads 311 on the screw rods 31 of the two first locking rods 30 is a left-handed thread and the other is a right-handed thread, and the internal threads provided on the threaded holes 223 corresponding to the screw rods 31 are matched with the external threads 311 .

[0046] The first transmission gear 21 drives the two output gears 22 to rotate synchronously in the same direction. The external threads 311 on the screw rods 31 of the two first locking rods 30, one of which is a left-handed thread and the other is a right-handed thread, allow one of the two locking rods 30 to extend and the other to retract synchronously. The corresponding charging gun needs to be locked according to user needs. Various embodiments of this design meet the diverse usage scenarios of the electronic lock; or in some embodiments, the external threads 311 on the screw rods 31 of the two first locking rods 30 are both left-handed threads or both right-handed threads, so that the two locking rods 30 can be extended and retracted synchronously, allowing the electronic lock to lock the DC charging gun and the AC charging gun at the same time.

[0047] In some embodiments, as Figure 5 As shown, the actuator also includes at least one actuator rod 40, on which a rack 41 is provided, and at least one output gear 22 includes a large gear 221 and a small gear 222 coaxially connected, the large gear 221 is engaged with the first transmission gear 21, and the small gear 222 is engaged with the rack 41. The rotation of the output gear 22 drives the actuator rod 40 to reciprocate on a predetermined moving path.

[0048] The same driving device 10 can drive the large gear 221 of the two output gears 22 to rotate through the first transmission gear 21. The rotation of the two large gears 221 drives the two small gears 222 to rotate synchronously. The rotation of the two small gears 222 synchronously drives the two locking rods 30 and at least one actuator rod 40 to reciprocate synchronously, thereby realizing the control of multiple rod bodies 32 by one driving device 10. The degree of integration is high, and the overall layout of the charging base is reduced. It can meet the locking requirements of diversified electronic locks, increase multiple rod bodies 32, improve the locking strength, ensure the reliable locking of the charging gun and the charging base, and ensure safe use during charging.

[0049] In some embodiments, as Figure 6 As shown, it also includes a housing 50, the driving device 10, the transmission mechanism 20 and the actuator are arranged in the housing 50, two locking holes 51 are provided on the housing 50, and the two locking rods 30 extend from the two locking holes 51 respectively.

[0050] The housing 50 protects the driving device 10, the transmission mechanism 20 and the actuator to prevent damage caused by collisions, integrates the various parts, makes them easy to install and use, and also plays a sealing role.

[0051] In some embodiments, as Figure 7 As shown, at least one slideway 52 is further provided in the housing 50 , and the actuator rod 40 is partially provided in the slideway 52 and can slide along the slideway 52 .

[0052] The slideway 52 serves to guide the actuator rod 40 to slide in the housing 50 .

[0053] In some embodiments, as Figure 5 As shown, there are two actuator rods 40 , and the two output gears 22 include a large gear 221 and a small gear 222 that are coaxially connected. The two actuator rods 40 are respectively meshed with and transmission-connected to the two small gears 222 .

[0054] The structural design here allows the driving device 10 to rotate through the first transmission gear 21, and the rotation of the first transmission gear 21 then drives the two locking rods 30 and the two actuator rods 40 to reciprocate synchronously through the two output gears 22. The degree of integration is high, and the overall layout of the charging base is reduced. It can not only meet the locking requirements of various electronic locks, but also improve the locking strength, ensure the reliable locking of the charging gun and the charging base, and ensure safe use during charging.

[0055] In some embodiments, a potentiometer or micro switch 60 (such as a micro switch 60) is provided in the housing 50 and can abut against the actuator rod 40. Figure 8 shown) or cam structure.

[0056] During the movement of the actuator rod 40, the micro switch 60 is triggered, so that the reciprocating position of the actuator rod 40 is monitored, and the extension and retraction of the actuator rod 40 can be accurately controlled according to the use requirements. Alternatively, the actuator rod 40 is connected to the movable contact of the potentiometer, so that the real-time position of the actuator rod 40 is monitored, and the reciprocating motion of the actuator rod 40 is better controlled;
