Description

Technical Field

[0001] This utility model relates to the technical field of automatic locks, and in particular to an electronic lock for vehicles and a charging socket for vehicles. Background Technology

[0002] In recent years, with the rise of new energy technologies, the electric vehicle industry has experienced unprecedented rapid development. Currently, several domestic and international car brands have already launched mass-produced electric vehicles. The charging safety and reliability of electric vehicles are receiving increasing attention from all sectors of the electric vehicle industry. Electronic locks on charging interfaces provide a guarantee for the safety of electric vehicle charging.

[0003] The charging interface is a charging component used to connect the power cable to the electric vehicle, consisting of a charging plug and a charging socket. During conductive charging of the electric vehicle, the charging plug is inserted into the charging socket, and charging is achieved through structural and electrical coupling with the socket. The electronic lock is used to lock the charging plug and socket together; it is typically installed on the socket and integrated with it. When the electronic lock pin is in the locked state, the plug is locked to the socket, ensuring a reliable connection. When charging is complete, the system sends an unlock signal, and the electronic lock pin is unlocked. The charging plug can then be removed from the charging socket, completing the charging process.

[0004] Traditional electronic locks are usually integrated with the wiring harness. The wiring harness is soldered onto the product, which not only makes maintenance difficult and costly, but also poses potential risks due to the soldering process. Utility Model Content

[0005] This utility model addresses the technical problems of difficult maintenance, high maintenance costs, and potential risks associated with welding processes caused by wire harness welding by providing an electronic lock for vehicles and a charging socket for vehicles.

[0006] This utility model provides an electronic lock for vehicles, including a housing. The housing contains a motor, a transmission assembly, and a motion assembly. The transmission assembly includes a first-stage gear, a second-stage gear, a third-stage gear, and a fourth-stage gear that mesh sequentially. The motion assembly includes a fifth-stage rack that meshes with the fourth-stage gear. The fifth-stage rack is slidably connected to the housing, and a locking rod is provided on the fifth-stage rack. The locking rod is telescopically connected to the housing. The motor's shaft is fixedly connected to the first-stage gear. The motor sequentially drives the first-stage gear to rotate, the second-stage gear to rotate, the third-stage gear to rotate, the fourth-stage gear to rotate, the fifth-stage rack to move, and the locking rod to extend and retract.

[0007] Furthermore, one end of the five-stage rack plate is provided with a mounting hole, one end of the locking rod is inserted into the mounting hole, and the five-stage rack plate is provided with a locking element for fixing the locking rod in the mounting hole.

[0008] Furthermore, a first sealing element is provided between the locking rod and the housing, and a first sealing cover is provided between the first sealing element and the housing.

[0009] Furthermore, a charging switch is provided inside the housing, and a lever arm that can abut against the charging switch is provided on the five-stage rack plate. When the five-stage rack plate moves, the lever arm abuts against or releases from the charging switch.

[0010] Furthermore, the charging switch is a micro switch.

[0011] Furthermore, the housing is equipped with an emergency unlocking component.

[0012] Furthermore, the emergency unlocking component includes a lever and a swing arm. The lever is fixedly connected to the swing arm and is located outside the housing. The swing arm is located inside the housing. Both the lever and the swing arm are rotatably connected to the housing. After the swing arm rotates, it can abut against the moving component, causing the locking rod to retract.

[0013] Furthermore, the fifth-stage rack plate is provided with a force-bearing block, which protrudes from the surface of the fifth-stage rack plate. After the swing arm rotates, it can abut against the force-bearing block, and push the fifth-stage rack plate to move through the force-bearing block, thereby driving the locking rod to retract.

[0014] Furthermore, a second seal is provided between the actuator and the housing.

[0015] This utility model also provides a vehicle charging socket, including the vehicle electronic lock described in any of the above solutions.

[0016] The beneficial effects of this utility model are as follows: By setting up a motor, transmission components, and motion components, when the motor drives the first-stage gear to rotate, it drives the second-stage gear to rotate, then the third-stage gear to rotate, then the fourth-stage gear to rotate, and finally the fifth-stage rack plate to move. The movement of the fifth-stage rack plate enables the lock rod to move back and forth, achieving a telescopic effect, thereby realizing the locking or unlocking function of the vehicle electronic lock. This utility model's vehicle electronic lock achieves locking or unlocking through multi-stage gears, eliminating the need for wiring harnesses and allowing for complete separation of the product from wiring harnesses. This eliminates the hidden dangers caused by welding processes and also reduces the difficulty and cost of later maintenance, improving connection reliability. Moreover, the product is small in size, representing a compact new structure that is more convenient to use. Attached Figure Description

[0018] Figure 2 This is an exploded view of the electronic lock for vehicles according to this utility model. Detailed Implementation

[0019] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that the embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Moreover, the features in the embodiments of the present invention can be combined with each other without conflict.

[0020] like Figures 1-2 As shown, this utility model provides an electronic lock for vehicles, including a housing, within which a motor 2, a transmission assembly 3, and a motion assembly 4 are provided; the transmission assembly 3 includes a first-stage gear 31, a second-stage gear 32, a third-stage gear 33, and a fourth-stage gear 34 that mesh sequentially; the motion assembly 4 includes a fifth-stage rack plate 41 that meshes with the fourth-stage gear 34, the fifth-stage rack plate 41 being slidably connected to the housing, and a locking rod 42 being provided on the fifth-stage rack plate 41, which is telescopically connected to the housing; the rotating shaft of the motor 2 is fixedly connected to the first-stage gear 31, and the motor 2 sequentially drives the first-stage gear 31 to rotate, the second-stage gear 32 to rotate, the third-stage gear 33 to rotate, the fourth-stage gear 34 to rotate, the fifth-stage rack plate 41 to move, and the locking rod 42 to extend and retract.

[0021] In one specific embodiment, the housing includes an upper housing 11 and a lower housing 12 that cooperate with each other. The upper housing 11 contains hardware terminals, and the lower housing 12 serves to support and fix the various components. The motor 2, the transmission component 3, and the motion component 4 are all installed in the lower housing 12.

[0022] Motor 2 serves as the power source, providing power to transmission component 3 and driving its movement. Specifically, primary gear 31 is mounted on the shaft of motor 2, and rotates synchronously when the shaft of motor 2 rotates. Inside the lower housing 12, near the shaft of motor 2, are sequentially mounted secondary positioning shaft 35, tertiary positioning shaft 36, and quaternary positioning shaft 37, all aligned axially with the shaft of motor 2. These shafts are all rotatable within the lower housing 12, and secondary gear 32, tertiary gear 33, and quaternary gear 34 are respectively mounted on them, enabling their rotation. Since the first-stage gear 31 meshes with the second-stage gear 32, the second-stage gear 32 meshes with the third-stage gear 33, and the third-stage gear 33 meshes with the fourth-stage gear 34, when the first-stage gear 31 rotates, it can sequentially drive the second-stage gear 32, the third-stage gear 33, and the fourth-stage gear 34 to rotate. In this embodiment, the second-stage gear 32, the third-stage gear 33, and the fourth-stage gear 34 all include two rings of teeth with different radii, so that adjacent gears can mesh in a staggered manner, resulting in a more compact structure and higher space utilization. The above-mentioned gears and the positioning shaft form the transmission assembly 3, which enables the motion assembly 4 to move back and forth through gear linkage. In addition to gear linkage, linkage can also be achieved through racks, sprockets, chains, etc.

[0023] The fifth-stage rack plate 41 is installed inside the lower housing 12 and can be slidably connected to the lower housing 12. The upper surface of the fifth-stage rack plate 41 is provided with a rack that meshes with the fourth-stage gear 34. The fifth-stage rack plate 41 meshes with the fourth-stage gear 34 through the rack. When the fourth-stage gear 34 rotates, it drives the fifth-stage rack plate 41 to move. One end of the fifth-stage rack plate 41 is fixedly connected to the locking rod 42. Specifically, the end of the fifth-stage rack plate 41 that is fixedly connected to the locking rod 42 has a mounting hole 411. One end of the locking rod 42 is inserted into the mounting hole 411. The fifth-stage rack plate 41 is equipped with a locking member 412 for fixing the locking rod 42 in the mounting hole 411. The locking member 412 is a pin. The locking member 412 fixes and locks the locking rod 42 to prevent it from loosening. The lower housing 12 has a locking rod hole 121 near the locking rod 42 for the locking rod 42 to pass through. By moving the five-stage rack plate 41 back and forth, the locking rod 42 is driven to move back and forth in the locking rod hole 121, realizing the extension and retraction function of the locking rod 42, that is, realizing the locking or unlocking function of the vehicle electronic lock.

[0024] This invention, through the configuration of a motor 2, a transmission component 3, and a motion component 4, allows the motor 2 to drive the primary gear 31 to rotate, which in turn drives the secondary gear 32, the tertiary gear 33, and the quaternary gear 34, ultimately moving the quinary rack plate 41. This movement of the quinary rack plate 41 causes the locking rod 42 to move back and forth, achieving a telescopic effect and thus enabling the electronic lock to lock or unlock. This electronic lock achieves locking or unlocking through multi-stage gears, eliminating the need for wiring harnesses and allowing for complete separation of the product from the wiring harness. This eliminates potential problems associated with welding processes, reduces maintenance difficulties and costs, improves connection reliability, and features a compact, novel structure that is more convenient to use.

[0025] In one specific embodiment, a charging switch 5 for controlling charging is fixedly connected inside the lower housing 12 via two positioning posts. The charging switch 5 is a micro switch, which is more sensitive. A lever arm 43 that can abut against the charging switch 5 is fixedly connected to the fifth-stage rack plate 41 near the charging switch 5. The two ends of the lever arm 43 are a connecting section 431 and a functional section 432, respectively. The connecting section 431 is fixedly connected to the fifth-stage rack plate 41 to fix the lever arm 43 to the fifth-stage rack plate 41. The functional section 432 protrudes from the surface of the lever arm 43 by an inclined surface and is used to contact the charging switch 5. During the back-and-forth movement of the fifth-stage rack plate 41, the lever arm 43 moves back and forth, so that the functional section 432 of the lever arm 43 can abut against the charging switch 5 or release from the charging switch 5. The on / off function of the charging switch 5 is controlled by whether the functional section 432 is in contact with the charging switch 5, thereby realizing the charging or stopping of the electric vehicle.

[0026] In practical applications, the motor 2 is powered and receives switch signals via an external interface, connecting the motor 2 and the charging switch 5. When the vehicle electronic lock is in the unlocked state, the lever arm 43 is not in contact with the charging switch 5, and charging is not in progress. When the motor 2 drives the locking rod 42 to extend, the vehicle electronic lock turns into the locked state. At the same time, the functional segment 432 moves and contacts the charging switch 5, and the system starts supplying power, thus initiating charging. When charging is complete, the system sends an unlocking signal, the motor 2 drives the locking rod 42 to retract, the vehicle electronic lock turns into the unlocked state, and at the same time, the functional segment 432 moves and disengages from the charging switch 5, thus stopping charging.

[0027] This utility model's vehicle electronic lock is driven by a motor 2 and uses a micro switch as a position signal feedback device. It connects to an external control circuit via an external interface to achieve locking, unlocking, and signal feedback, controlling the entire charging process. Compared to traditional vehicle electronic locks with integrated wiring harnesses, the new structure eliminates the wiring harness's inherent wiring hazards caused by welding processes, optimizes the manufacturing process, and uses an external interface for easier maintenance and management.

[0028] In one specific embodiment, an emergency unlocking component 6 is installed on the housing near the moving component 4. The emergency unlocking component 6 includes a lever 61 and a swing arm 62. The lever 61 is rotatably inserted outside the upper housing 11, and the swing arm 62 is rotatably connected inside the lower housing 12. A rectangular block 621 is fixedly connected to the upper end of the swing arm 62, and a force-applying block 622 acting on the moving component 4 is fixedly connected to the lower end. The force-applying block 622 protrudes from the side of the swing arm 62. The lever 61 is essentially an unlocking knob. A rectangular hole 611 matching the rectangular block 621 is opened in the middle of the lever 61. The rectangular block 621 is vertically inserted into the rectangular hole 611. The lever 61 is fixedly connected to the swing arm 62, and the force-applying block 622 can be rotated horizontally by levering the lever 61.

[0029] On the other hand, the end of the fifth-stage rack plate 41 furthest from the locking rod 42 has an integrally formed force-receiving block 44 that cooperates with the force-applying block 622. The force-receiving block 44 protrudes from the surface of the fifth-stage rack plate 41 to facilitate its cooperation with the force-applying block 622. After the force-applying block 622 rotates, it acts on the force-receiving block 44, pressing against it. The force-receiving block 44 then pushes the fifth-stage rack plate 41 backward, thereby causing the locking rod 42 to retract. In the locked state of the vehicle electronic lock, by manually operating the lever 61, the swing arm 62 rotates, ultimately causing the fifth-stage rack plate 41 and the locking rod 42 to move backward. This provides power for emergency unlocking of the vehicle electronic lock, thus realizing the emergency unlocking function. Such a vehicle electronic lock has higher security performance.

[0030] In one specific embodiment, in order to improve the waterproof performance of the vehicle electronic lock, the upper housing 11 and the lower housing 12 are installed together and then ultrasonically welded to make the housing complete the overall waterproof function.

[0031] In one specific embodiment, a first sealing element 7 is further installed between the locking rod 42 and the lower housing 12. The first sealing element 7 is a sealing ring, which fills the space between the locking rod 42 and the lower housing 12, and plays a good waterproof role between the two.

[0032] In one specific embodiment, a first sealing cover 8 is provided between the first sealing member 7 and the lower housing 12. After the first sealing cover 8 is installed into the lower housing 12 by three internal buckles, it covers the first sealing member 7 and plays a role in fixing and limiting the first sealing member 7 to prevent it from loosening, thereby effectively ensuring the waterproof effect.

[0033] In one specific embodiment, a second sealing element 9 is further installed between the lever 61 and the upper housing 11. The second sealing element 9 is also a sealing ring. The second sealing element 9 fills the space between the lever 61 and the upper housing 11, and plays a good waterproof role between the two.

[0034] This utility model also provides a vehicle charging socket, including the vehicle electronic lock in any of the above specific embodiments. The vehicle electronic lock is installed on the charging socket and plays a role in providing a reliable connection during charging.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
