DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0030] Any number of elements in the drawings is for illustration and not limitation, and any naming is for distinction only and does not have any limiting meaning.

[0031] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0032] The electronic lock for the charging socket of a new energy vehicle provided by the utility model has an anti-retraction structure. Figures 1 to 9As shown, it includes a shell 1, a locking rod 2, and a driving mechanism 3 for driving the locking rod 2 to extend and retract along the shell 1. The driving mechanism 3 includes a sliding seat 31, a linkage assembly 32, and a driving gear 33 that are linked and matched. The linkage assembly 32 includes a mounting rod 321 and a linkage gear 1 322. A fixing piece 11 for fixing the mounting rod 321 is provided on the shell 1. An anti-retraction structure for preventing the locking rod 2 from retreating is provided in the shell 1. The anti-retraction structure includes a convex rib 112 provided on a side of the fixing piece 11 facing the linkage gear 1 322. A limiting groove 3211 is provided on one end of the mounting rod 321 facing the linkage gear 1 322. The limiting groove 3211 and the outer wall of the mounting rod 321 form a step surface 3212. The linkage gear 1 322 is sleeved on the outer wall of the mounting rod 321 and is installed between the convex rib 112 and the step surface 3212. In this embodiment, the driving gear 33 is linked and connected with a motor 34 for driving the driving gear 33 to rotate.

[0033] By adopting the above technical scheme, through the linkage-coordinated sliding seat 31, linkage assembly 32, and driving gear 33, efficient transmission of driving the lock rod 2 to extend and retract along the shell 1 is achieved, energy loss in the transmission process is reduced, and transmission efficiency is improved. Through the cooperation of the mounting rod 321, linkage gear 1 322, convex rib 112, and step surface 3212, linkage gear 1 322 is clamped between the convex rib 112 and the step surface 3212, so that stable installation of the linkage gear 1 322 on the mounting rod 321 is achieved, and the relative movement between components is reduced, which can effectively improve the overall structural stability of the electronic lock. During the locking process, the lock rod 2 will have a certain reverse rotation due to the reverse electromotive force of the motor 34. During the reverse rotation of the motor 34, the clamping force eliminates the reverse torque, thereby achieving the elimination of the reverse rotation of the motor 34, which can effectively prevent the lock rod 2 from retreating and ensure the stability of the lock rod 2 when it is extended.

[0034] In this embodiment, the height of the rib 112 is 0.45 mm, and the interference with the linkage gear 322 is 0.25-0.35 mm. The clamping force is 5-8N, which can offset the reverse retreat force.

[0035] When the driving gear 33 rotates, the linkage gear 1 322 rotates accordingly, thereby driving the linkage gear 2 323 to rotate. The rotation of the linkage gear 2 323 drives the sliding seat 31 to slide along the housing 1 through the interaction between the teeth, thereby finally realizing the telescopic function of the locking rod 2, which not only improves the safety of the charging socket, but also ensures the convenience of operation and is more practical.

[0036] In this embodiment, a fixing groove is provided on the sliding seat 31, and the lock rod 2 is embedded in the fixing groove and fixed by a fixing pin. The fixing pin passes through the side wall of the fixing groove and the lock rod 2, which is convenient for disassembly and replacement of the lock rod 2, and can extend the service life of the electronic lock.

[0037] In this embodiment, the driving gear 33 and the linkage gear 1 322 are both bevel gears, and the central axes of the driving gear 33 and the linkage gear 1 322 are perpendicular to each other. The linkage gear 2 323 is a standard gear. The central axes of the linkage gear 1 322 and the linkage gear 2 323 coincide with each other. The meshing teeth of the rack segment 311 and the meshing teeth of the linkage gear 2 323 are parallel to each other, which optimizes the spatial layout, makes the transmission mechanism more compact, reduces the volume and weight of the entire electronic lock, ensures a smooth transition from the bevel gear to the standard gear, reduces the energy loss in the transmission process, ensures the stability and efficiency of the transmission, and enables the sliding seat 31 to slide smoothly along the shell 1.

[0038] In this embodiment, the sliding seat 31 also includes a limiting section 312 and a fixed section 313. The rack section 311 is located between the limiting section 312 and the fixed section 313. Based on the bottom end surface of the sliding seat 31, the heights of the limiting section 312 and the fixed end are both higher than the height of the rack section 311, ensuring that the movement range of the sliding seat 31 is effectively limited when it slides along the shell 1. The travel length of the sliding seat 31 is the length of the rack section 311. The side end surface of the limiting section 312 facing the shell 1 is movably abutted against the inner wall of the shell 1, further limiting the sliding stroke of the sliding seat 31.

[0039] In the present embodiment, a micro switch assembly 4 is also included. The micro switch assembly 4 includes a circuit board 41 and a sensing key 42 located on the circuit board 41. A mounting seat 43 is provided on one side of the sensing key 42. The mounting seat 43 is rotatably connected to a trigger lever 44. The trigger lever 44 abuts against the sensing switch on the sensing key 42. The fixed section 313 is provided with an extension portion 3131. The extension portion 3131 abuts against the trigger lever 44. A fixed shaft 431 is provided on the mounting seat 43. The trigger lever 44 is provided with a rotating member 441. The rotating member 441 is sleeved on the outer wall of the fixed shaft 431 and rotatably cooperates with the outer wall of the fixed shaft 431. The circuit board 41 serves as the basis of the micro switch assembly 4. Necessary circuit elements are arranged to receive and process signals from the sensing key 42. The sensing switch on the sensing key 42 is responsible for detecting the action state of the trigger lever 44. The mounting seat 43 is used to support and fix the rotating structure of the trigger lever 44. The trigger lever 44 is connected to the fixed shaft 431 on the mounting seat 43 through its rotating member 441, thereby realizing the rotatable function. When the trigger lever 44 is subjected to external force, it will rotate around the fixed shaft 431. When the trigger lever 44 rotates, it will come into contact with or separate from the sensing switch, thereby triggering or closing the sensing key 42. The extension portion 3131 slides synchronously with the sliding seat 31 to apply pressure to the trigger lever 44, which is used to drive the trigger lever 44 to rotate.

[0040] In this embodiment, when the lock rod 2 retracts and retracts, the extension portion 3131 presses against the trigger lever 44, and the trigger lever 44 rotates accordingly according to the lever principle. Depending on the direction of rotation, the trigger lever 44 contacts or separates from the sensing switch on the sensing key 42. When the trigger lever 44 contacts the sensing switch, the sensing switch is triggered and generates an electrical signal; when the trigger lever 44 separates from the sensing switch, the sensing switch returns to an untriggered state. These electrical signals are transmitted to the control part of the electronic lock system (such as the vehicle control system) to determine the state of the lock rod 2 (such as whether it is locked, unlocked, etc.).

[0041] In this embodiment, the micro switch assembly 4 includes two groups, and the two groups of micro switch assemblies 4 are symmetrically distributed. The trigger lever 44, the sliding seat 31, and the locking rod 2 are parallel to each other. When the sliding seat 31 slides, the two groups of micro switch assemblies 4 respond respectively. When the sliding seat 31 drives the locking rod 2 to extend out of the shell 1, the extension portion 3131 triggers the trigger lever 44 in the micro switch assembly 4 toward the side of the locking rod 2. When the sliding seat 31 drives the locking rod 2 to retract into the shell 1, the extension portion 3131 triggers the trigger lever 44 in the micro switch assembly 4 away from the side of the locking rod 2. The two groups of micro switch assemblies 4 respectively transmit different signals to the control system of the electronic lock, which is convenient for the user to judge the status of the locking rod 2.

[0042] In this embodiment, the extension portion 3131 is provided with an open groove 301, and the side walls of the extension portion 3131 located on both sides of the open groove 301 respectively abut against the trigger levers 44 of the two groups of micro switch assemblies 4, so that the extension portion 3131 can only abut against the trigger lever 44 of a single micro switch assembly 4, thereby ensuring accurate signal transmission and avoiding the extension portion 3131 simultaneously actuating the two groups of trigger levers 44 to cause signal transmission errors. It should be noted that the design of the extension portion 3131 and the open groove 301 needs to take into account the layout and size of the two groups of micro switch assemblies 4. Through reasonable arrangement and calculation, it can be ensured that the extension portion 3131 can accurately cooperate with the single trigger lever 44 during operation while avoiding interference or conflict with other components.

[0043] In this embodiment, the circuit board 41 is fixed in the housing 1 by screws. A movable groove 411 is provided on the side of the circuit board 41 facing the sliding seat 31. The fixed section 313 and the movable groove 411 are movably abutted against each other, further limiting the sliding stroke of the sliding seat 31 and effectively saving space.

[0044] In this embodiment, the fixed section 313 is provided with a mounting groove 3132, and a manual unlocking rope 3133 is provided on the fixed section 313. The manual unlocking rope 3133 includes an end 302, and the end 302 is located in the mounting groove 3132. The manual unlocking rope 3133 passes through the side wall of the mounting groove 3132. The manual unlocking rope 3133 can be used to manually operate the unlocking mechanism in the event of power failure, electronic control failure or other emergency situations. It should be noted that the side wall of the mounting groove 3132 is provided with a through hole, and the connecting rope of the manual unlocking rope 3133 passes through the side wall of the mounting groove 3132 through the through hole. The diameter of the end 302 of the manual unlocking rope 3133 is larger than the diameter of the through hole. When the manual unlocking rope 3133 is manually pulled, the end 302 of the manual unlocking rope 3133 drives the sliding seat 31 to slide, so that the locking rod 2 can be retracted back into the shell 1, thereby realizing manual unlocking of the electronic lock.

[0045] In this embodiment, a guide plate 314 is provided on the side of the fixed section 313 of the sliding seat 31 facing the manual unlocking rope 3133, and a guide track is provided on the guide plate 314, so that the manual unlocking rope 3133 can move along a predetermined path during the pulling process and limit the moving trajectory of the manual unlocking rope 3133, ensuring that it remains stable during the pulling process and does not deviate from the predetermined path.

[0046] In this embodiment, a groove 111 for supporting the end of the mounting rod 321 is provided on the fixing member 11 , and the mounting rod 321 is fixed in the housing 1 by being engaged with the groove 111 .

[0047] In this embodiment, the two ends of the mounting rod 321 extend in a direction away from the linkage gear 1 322 and the linkage gear 2 323 respectively. The fixing member 11 includes two groups, namely the fixing member 113 and the fixing member 2 114. The width of the groove 111 on the fixing member 113 is smaller than the width of the groove 111 on the fixing member 2 114. The end of the mounting rod 321 facing the linkage gear 1 322 is engaged with the groove 111 on the fixing member 1 113, and the end of the mounting rod 321 facing the linkage gear 2 323 is engaged with the groove 111 on the fixing member 2 114. Due to the setting of the limiting groove 3211, the diameters of the two ends of the mounting rod 321 are different. Therefore, there is a width difference between the fixing member 1 113 and the fixing member 2 114, which is convenient for the user to identify the installation direction of the mounting rod 321 during installation, and ensures that the mounting rod 321 can be smoothly and accurately embedded in the groove 111.

[0048] In this embodiment, the shell 1 includes an upper cover 13 and a lower shell 14 that are detachably connected. The upper cover 13 and the lower shell 14 can be detachably connected by various means such as screws and interlocking connections. The locking rod 2, the driving mechanism 3, and the fixing frame are all located in the lower shell 14. A stabilizing member 132 is provided on the side of the upper cover 13 facing the lower shell 14. The stabilizing member 132 is interlocked with the groove 111 on the fixing member 11, and the stabilizing member 132 is abutted against the outer wall of the end of the mounting rod 321, which can make the mounting rod 321 more stable.

[0049] In this embodiment, a downwardly extending pressing plate 131 is provided on the side of the upper cover 13 facing the locking rod 2, and an avoidance groove 1311 that is movably engaged with the locking rod 2 is provided on the pressing plate 131. There is a gap between the pressing plate 131 and the outer wall of the lower shell 14, and a sealing ring 15 is provided in the gap. The sealing ring 15 is sleeved on the outer wall of the locking rod 2, and a seal is formed between the sealing member and the locking rod 2. The sealing method is a rib seal. A limit block 141 is provided on the outer wall of the lower shell 14, and the limit block 141 includes two groups and is respectively located on both sides of the clamping plate 131. The two groups of limit blocks 141 are both arranged in an L-shaped structure and the two groups of limit blocks 141 are arranged opposite to each other. The clamping plate 131 and the limit blocks 141 are fitted together to ensure the stability of the installation of the seal and the stability of the top fit between the clamping plate 131, the seal and the outer wall of the lower shell 14. A seal is formed between the clamping plate 131, the outer wall of the lower shell 14 and the sealing ring 15, and the sealing method is a surface pressure seal.
