DETAILED DESCRIPTION
[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0027] The embodiment of the present application provides an electronic lock structure for a new energy vehicle charging socket, which can solve the problem in the related art that an electronic lock rod is caused to retreat due to external force, resulting in charging failure.
[0028] See also Figure 1-Figure 3 , an electronic lock structure of a new energy vehicle charging socket comprises: a shell 1, a retractable lock rod 2 is arranged on the shell 1, the lock rod 2 is docked with an external charging gun to charge the car, a lock block 3 is arranged at one end of the lock rod 2, the lock block 3 is slidably arranged inside the shell 1, and a locking groove 4 is arranged on the lock block 3;
[0029] A driving member 5 is arranged inside the shell 1, and a locking cam 6 is rotatably arranged inside the shell 1. A fixed rod 7 is arranged on the locking cam 6. The driving member 5 is used to drive the locking cam 6 to rotate. The rotation of the locking cam 6 can drive the fixed rod 7 to extend into the locking groove 4 and limit the locking block 3.
[0030] Initial state: before the charging gun is inserted, the locking rod 2 is in a retracted state, the locking block 3 is located at an initial position inside the housing 1 , and the fixed rod 7 is not in contact with the locking groove 4 .
[0031] Charging gun insertion: As the charging gun is inserted, the driving member 5 starts to work, driving the locking cam 6 to rotate, and the fixed rod 7 on the locking cam 6 gradually approaches and finally extends into the locking groove 4 on the locking block 3 as the cam rotates. Once the fixed rod 7 fully enters the locking groove 4, it forms a mechanical lock, restricting the movement of the locking block 3, thereby ensuring a stable connection between the charging gun and the socket.
[0032] In the locked state, the charging gun starts charging the electric vehicle. Due to the presence of the locking mechanism, the charging gun can maintain a stable connection state even if it is affected by external forces such as the user shaking the charging gun.
[0033] After charging is completed, the driving member 5 drives the locking cam 6 to rotate in the reverse direction, so that the fixed rod 7 withdraws from the locking groove 4, and the locking rod 2 is retracted under the action of a spring or other reset mechanism, thereby unlocking the charging gun and allowing the user to pull it out.
[0034] By adding a mechanical locking mechanism, the external retraction force is effectively resisted, ensuring a firm connection between the charging gun and the socket, and avoiding charging interruptions or fault alarms caused by improper user operation.
[0035] The stable charging connection reduces the risk of safety accidents caused by accidental detachment of the charging gun, protects the battery system and charging facilities of the electric vehicle, reduces the inconvenience and trouble caused by charging interruptions, and improves the overall satisfaction of users with electric vehicles and charging facilities.
[0036] This structure can be applied to various types of new energy vehicle charging interfaces and has strong versatility and adaptability.
[0037] It should be noted that, in this embodiment, a mounting seat 8 is provided on one side of the housing 1, the locking rod 2 is rotatably provided inside the mounting seat 8, and one end of the locking rod 2 extends into the housing 1. A spring connected to the locking rod 2 is provided inside the mounting seat 8. The spring is a tension return spring, which can allow the locking rod 2 to be extended and retracted, and at the same time position the locking rod 2.
[0038] In this embodiment, the diameter of the fixed rod 7 is the same as the width of the locking groove 4. The locking groove 4 is rectangular, and the bottom of the locking groove 4 is arc-shaped. A sliding groove for the locking block 3 to slide is provided inside the housing 1.
[0039] The diameter of the fixed rod 7 is the same as the width of the locking groove 4, ensuring that the fixed rod 7 can fit tightly into the locking groove 4 without any gap or looseness, which helps to achieve a more stable locking effect and reduce the risk of unlocking due to external force.
[0040] The chute provides a clear movement trajectory and support for the lock block 3. When the lock rod 2 is extended or retracted, the lock block 3 will slide along the chute. The design of the chute helps to ensure the stability and reliability of the lock block 3 during movement, preventing it from deviating from the predetermined trajectory or being subjected to unnecessary resistance. At the same time, the chute can also play a guiding and limiting role, ensuring that the lock block 3 can accurately dock with the fixed rod 7 or the corresponding structure on the charging gun when it is in a specific position.
[0041] Further, such as Figure 2 and Figure 6 In the present embodiment, the locking cam 6 includes a rotating shaft 61, a gear 2 62 and a mounting block 63. The rotating shaft 61 is rotatably arranged inside the housing 1. The gear 2 62 and the mounting block 63 are sequentially arranged on the rotating shaft 61. A mounting groove 64 is provided on the mounting block 63. The fixed rod 7 is arranged at one end inside the mounting groove 64.
[0042] Gear 2 62 is disposed on the rotating shaft 61 , and its function is to transmit the power from the driving member to the rotating shaft 61 .
[0043] The mounting block 63 is also a component arranged on the rotating shaft 61, and is mainly used for mounting and fixing the fixed rod 7. The placement groove 64 provided on the mounting block 63 provides a stable mounting environment for the fixed rod 7, and allows the fixed rod 7 to move along a certain track when necessary.
[0044] The placement groove 64 is a key feature on the mounting block 63, and it is used to accommodate one end of the fixed rod 7. The shape and size of the placement groove 64 should match the fixed rod 7 to ensure that the fixed rod 7 can be stably installed therein.
[0045] The fixed rod 7 is one of the key components in the locking mechanism, and is arranged at one end inside the placement groove 64. When the locking cam 6 rotates, the mounting block 63 and the fixed rod 7 will move together. During the locking process, the fixed rod 7 will extend into the locking groove 4 on the locking block 3 to achieve a stable connection between the charging gun and the socket.
[0046] Further, such as Figure 3 and Figure 5 In this embodiment, the driving member 5 includes a driving motor 51, a worm gear 52 and a worm 53. The driving motor 51 is arranged inside the housing 1, the worm gear 53 is connected to the output shaft of the driving motor 51, the worm gear 52 is rotatably arranged inside the housing 1, a connecting disk 54 is detachably connected to the worm gear 52, and a gear 1 55 is detachably connected to the other side of the connecting disk 54, and the gear 1 55 is meshed with the gear 2 62.
[0047] The driving motor 51 serves as the power source of the entire driving system. It can start, stop or change the direction of rotation according to the control signal, thereby driving the movement of subsequent transmission components.
[0048] The worm 53 is connected to the output shaft of the driving motor 51, and transmits the rotational motion of the motor to the worm wheel 52. The cooperation between the worm and the worm wheel has a large transmission ratio and self-locking property, which can ensure a stable transmission relationship during the locking process and prevent reverse rotation caused by external force.
[0049] The worm wheel 52 is rotatably arranged inside the housing 1 and meshes with the worm 53. When the worm 53 rotates, the worm wheel 52 rotates accordingly and transmits the rotational motion to the subsequent connecting disk 54 and gear 1 55.
[0050] The connecting plate 54 is detachably connected to the worm gear 52, and it plays the effect of transition and connection. Through the connecting plate 54, the rotary motion of the worm gear 52 can be transmitted to the gear one 55 steadily, and it is convenient to install, disassemble and maintain the transmission component at the same time.
[0051] Gear 1 55 is detachably connected to the other side of the connecting plate 54 and meshes with gear 2 62 on the locking cam 6. When gear 1 55 rotates, it drives gear 2 62 and the locking cam 6 to rotate together, thereby achieving control of the fixed rod 7 and the action of the locking mechanism.
[0052] In this embodiment, two sets of support seats are arranged opposite to each other inside the housing 1, and the rotating shaft 61 and the worm gear 52 are rotatably arranged on the corresponding support seats.
[0053] like Figure 4 and Figure 6 As shown, in this embodiment, the housing 1 is provided with an interface 9, and an adapter sheet 10 is provided inside the housing 1. The interface 9 and the adapter sheet 10 are connected via a plurality of electrodes, and a conductive sheet 11 is provided on the adapter sheet 10; the locking block 3 is provided with a groove for accommodating the conductive sheet 11. When the locking rod 2 is in an extended state and the locking block 3 is fixed by the fixed rod 7, the conductive sheet 11 is located inside the groove of the locking block 3, and the two fit each other. When the fixed rod 7 is separated from the locking groove 4, the locking rod 2 is retracted and drives the locking block 3 to slide, so that the conductive sheet 11 is separated from the groove on the locking block 3.
[0054] The interface 9 is provided on the housing 1 and is used for transmitting power, signals or data.
[0055] The adapter 10 is located inside the housing 1 and acts as an intermediary for electrical connection. The adapter 10 is connected to the interface 9 through a plurality of electrodes to ensure that power or signals can be smoothly transmitted to the internal circuit.
[0056] The conductive sheet 11 is disposed on the adapter sheet 10 and is a key component of the electrical connection. When the lock rod 2 is in the extended state and the lock block 3 is fixed in the lock groove 4 by the fixed rod 7, the conductive sheet 11 will enter the groove opened on the lock block 3 and fit with the inner wall of the groove or a specific contact point, thereby establishing an electrical connection.
[0057] The groove on the locking block 3 is for accommodating the conductive sheet 11 and forming a close electrical contact with the conductive sheet 11 in the locked state. The shape and size of the groove should match the conductive sheet 11 to ensure the fit and contact stability between the two.
[0058] When the lock rod 2 is in the extended state and the lock block 3 is fixed in the lock groove 4 by the fixed rod 7, the conductive sheet 11 fits with the groove on the lock block 3 to form an electrical connection. This connection may be used to transmit charging signals, control signals or data communication.
[0059] When unlocking is required, such as when charging is completed or an abnormal situation occurs, the driving member 5 drives the locking cam 6 to rotate, so that the fixed rod 7 is disengaged from the locking groove 4. Subsequently, the locking rod 2 is retracted and drives the locking block 3 to slide in the slide groove. During this process, the conductive sheet 11 gradually disengages from the groove as the locking block 3 moves, thereby disconnecting the electrical connection. This disconnection of the electrical connection can be used as a signal for unlocking or safety disconnection, ensuring that no erroneous transmission of power or signals occurs during the unlocking process.
