Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4 As shown, a novel electronic lock includes a lower housing 1 and an upper housing 2. The upper housing 2 is located on the top of the lower housing 1. A drive assembly 3 and a buffer assembly 8 are respectively arranged inside the lower housing 1. A locking rod 4 and a pull rope 7 are respectively arranged on one side of the drive assembly 3. A connecting pipe 6 is fixedly connected to one side of the lower housing 1, and the pull rope 7 is located inside the connecting pipe 6. Oil injection assembly 5 includes a vertical pipe 51 connected to the inner wall of the upper housing 2. The top and bottom of the vertical pipe 51 are respectively connected to an oil injection hopper 52 and an L-shaped pipe 53. Both ends of the L-shaped pipe 53 are connected to oil outlets 54. The inner wall of the lower housing 1 is provided with a through hole 55. The interior of the lower housing 1 is provided with a collection chamber 56. The through hole 55 and the collection chamber 56 are connected.

[0018] The oil injection assembly 5 also includes an oil drain pipe 57 connected to the inner wall of the lower housing 1. A valve is provided on the outside of the oil drain pipe 57, and one end of the oil drain pipe 57 is connected to the collection chamber 56.

[0019] Lubricating oil is poured into the oil filling hopper 52. The oil enters the L-shaped pipe 53 through the vertical pipe 51 and is then diverted through the L-shaped pipe 53 to flow from the oil outlets 54 at both ends onto the drive assembly 3. The oil dripping into the lower housing 1 flows through the through hole 55 into the collection chamber 56. Personnel can open the valve on the drain pipe 57 to collect the oil, thereby completing the maintenance work on the drive assembly 3 without disassembling the electronic lock, thus improving work efficiency.

[0020] The drive assembly 3 includes a motor 31 disposed on the inner wall of the lower housing 1. The output end of the motor 31 is fixedly connected to a drive wheel 32. The outer side of the drive wheel 32 is meshed with a first driven wheel 33. The inner ring of the first driven wheel 33 is fixedly connected to a connecting shaft 34. The outer side of the connecting shaft 34 is fixedly connected to a second driven wheel 35. The outer side of the second driven wheel 35 is meshed with a toothed plate 36. One end of the connecting shaft 34 is rotatably connected to the inner wall of the lower housing 1 through a bearing seat. One side of the toothed plate 36 is fixedly connected to one end of the locking rod 4. One end of the L-shaped tube 53 is located directly above the drive wheel 32 and the first driven wheel 33. The other end of the L-shaped tube 53 is located directly above the second driven wheel 35 and the toothed plate 36.

[0021] The motor 31 drives the drive wheel 32 to rotate forward and backward, and the drive wheel 32 drives the first driven wheel 33 to rotate forward and backward. At this time, the connecting shaft 34 drives the second driven wheel 35 to rotate forward and backward, so that the toothed plate 36 can drive the locking rod 4 to move forward or backward, thereby completing the locking and unlocking after the charging gun is connected to the charging base.

[0022] The toothed plate 36 includes a guide groove 361 and a guide rail 362. The bottom of the toothed plate 36 has a guide groove 361, and the inner wall of the lower housing 1 is fixedly connected to the guide rail 362 that works with the guide groove 361. When the toothed plate 36 moves, the guide rail 362 can slide in the guide groove 361. Through the cooperation of the two, the toothed plate 36 can drive the locking rod 4 to move stably.

[0023] The pull rope 7 includes a handle 71 and a limiting block 72. One end of the pull rope 7 is fixedly connected to the handle 71, and the other end of the pull rope 7 is fixedly connected to the limiting block 72, which is located inside the toothed plate 36.

[0024] When the motor 31 is de-energized, the pull rope 7 is moved by pulling the handle 71. Under the action of the limit block 72, the pull rope 7 can drive the toothed plate 36 to move backward, thereby completing the manual unlocking.

[0025] The buffer assembly 8 includes a connecting seat 81 disposed on one side of the toothed plate 36. The top of the connecting seat 81 is provided with two sets of metal springs 82, and the bottom of the two sets of metal springs 82 is provided with cross-shaped connecting posts 83. The bottom of the two sets of cross-shaped connecting posts 83 is fixedly connected with springs 84.

[0026] Both sets of metal springs 82 are located inside the toothed plate 36. The top of the cross-shaped connecting post 83 is arc-shaped and abuts against the bottom of the metal spring 82. The connecting seat 81 is fixed to the inner wall of the lower housing 1 by screws.

[0027] When the toothed plate 36 moves back and forth, it can compress two sets of metal springs 82. The compression of the metal springs 82 causes the cross-shaped connecting column 83 to move into the connecting seat 81. At this time, the spring 84 is compressed. The metal springs 82 and the spring 84 can absorb and alleviate the impact and vibration generated when the toothed plate 36 moves, protecting the mechanical parts from damage.

[0028] Working principle: When maintenance is required, lubricating oil is poured into the oil filling hopper 52. The oil enters the L-shaped pipe 53 through the vertical pipe 51 and then flows through the oil outlets 54 at both ends of the L-shaped pipe 53, flowing between the driving wheel 32, the first driven wheel 33, the second driven wheel 35, and the gear plate 36, respectively, reducing gear wear. The oil that drips into the lower housing 1 then flows through the through hole 55 into the collection chamber 56. Personnel can open the valve on the drain pipe 57 to collect the oil, thereby completing the maintenance work of the drive component 3 without disassembling the electronic lock, which improves work efficiency.
