Description

Technical Field

[0001] This utility model relates to the field of safety protection technology for new energy vehicles, specifically an electronic locking mechanism for new energy vehicles. Background Technology

[0002] With the rapid development of new energy vehicle technology, the locking security and ease of operation of key vehicle components have become one of the core needs of users. Among them, the locking protection of charging interfaces, power battery compartment doors and key opening and closing components of the vehicle body are core aspects that are directly related to vehicle safety, property protection and emergency escape efficiency.

[0003] In the scenario of protecting the charging interface of new energy vehicles, the electronic locking mechanism must first meet the locking protection requirements, and at the same time check the sealing of the protective box, the meshing of the transmission components and the reliability of the power line connection. It can only be put into use after confirming that there are no abnormalities. However, in the process of using the existing electronic locking mechanism, when the electronic device fails and the lock body is mechanically locked, it is necessary to unlock it by pulling the emergency rope. People with less strength often have to apply a pulling force far beyond their physical strength to push the lock cylinder to move, making it difficult for such people to unlock independently. This not only delays the handling time, but also causes the rope to break and the lock cylinder to jam due to repeated pulling. Furthermore, when the transmission components operate for a long time in extreme environments, the internal friction resistance of the electronic locking mechanism is easily increased, which can easily lead to the overall transmission jamming.

[0004] Therefore, it is necessary to provide an electronic locking mechanism for new energy vehicles to solve the above-mentioned technical problems. Utility Model Content

[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 Figure 1-7 As shown, an electronic locking mechanism for new energy vehicles includes a protective box 1 and a power cord 2. The power cord 2 is located on one side of the protective box 1. A locking component 3 is provided inside the protective box 1. The locking component 3 includes a toothed plate 31 that is slidably connected to the inner wall of the protective box 1. A motor 32 is fixedly installed on the inner wall of the protective box 1. A locking rod 33 is fixedly connected to one side of the toothed plate 31. An output component 4 is provided inside the protective box 1. An unlocking component 5 is provided inside the toothed plate 31. The unlocking component 5 includes a steel rope 51 that is slidably connected to the inner wall of the toothed plate 31. One end of the steel rope 51 is fixedly connected to a limit block 52.

[0018] The protective box 1 serves as the outer shell of the entire locking mechanism, protecting the internal parts and ensuring their stable operation under complex vehicle conditions. The power cord 2 transmits electrical energy to the motor 32. The bottom of the toothed plate 31 has teeth that mesh with the teeth on the surface of the first gear 44. The motor 32 drives the first bevel gear 41 to rotate. Since the other end of the steel rope 51 is fixedly connected to the coil 62 and the limiting block 52 is located inside the toothed plate 31, when the steel rope 51 moves the limiting block 52, it can move the toothed plate 31 backward, thereby moving the locking rod 33 backward to unlock.

[0019] Specifically, the output component 4 includes a first bevel gear 41 fixedly connected to the output end of the motor 32, a transmission rod 42 rotatably connected to the bottom of the protective box 1, and a second bevel gear 43 and a first gear 44 respectively installed at both ends of the transmission rod 42, and the teeth on the surface of the first bevel gear 41 mesh with the teeth on the surface of the second bevel gear 43.

[0020] The first bevel gear 41 drives the second bevel gear 43 and the transmission rod 42 to rotate. When the transmission rod 42 rotates, the first gear 44 rotates synchronously, causing the first gear 44 to drive the tooth plate 31 to move back and forth, thereby driving the locking rod 33 to move forward or backward to complete locking and unlocking.

[0021] Specifically, the rope take-up component 6 is disposed at one end of the steel rope 51. The rope take-up component 6 includes a positioning box 61 disposed at one end of the steel rope 51; the rope take-up component 6 also includes a coil 62 rotatably connected to the inner wall of the positioning box 61, and a toothed ring 63 is fixedly connected to the side of the coil 62; the rope take-up component 6 also includes a second gear 64 rotatably connected to the inner wall of the positioning box 61, and the teeth on the surface of the second gear 64 mesh with the teeth on the surface of the toothed ring 63; the rope take-up component 6 also includes a limiting piece 65 rotatably connected to the inner wall of the positioning box 61, a first spring 66 is fixedly connected to one side of the limiting piece 65, and one end of the first spring 66 is fixedly connected to the inner wall of the positioning box 61; a lever 67 and a turntable 68 are rotatably connected to the side of the positioning box 61 respectively.

[0022] The positioning box 61 is used to support the reel 62, which is used to reel in the steel rope 51. The turntable 68 is fixedly connected to the second gear 64 via a rotating shaft. The lever 67 is fixedly connected to the limiting plate 65 via a rotating shaft. Rotating the turntable 68 drives the second gear 64 to rotate, which in turn drives the gear ring 63 and the reel 62 to rotate, reeling in the steel rope 51 and causing the limiting block 52 to move backward. At this time, the limiting plate 65, in cooperation with the first spring 66, can prevent the gear ring 63 from reversing. The coefficient of the first spring 66 is 0.5 to 3 N / mm. Moving the lever 67 causes the limiting plate 65 to move. At this time, the limiting plate 65 will not limit the gear ring 63. Then, the motor 32 is started to drive the gear plate 31 to move forward, which in turn drives the limiting block 52 to move forward, thereby resetting the position for the next emergency unlocking.

[0023] Specifically, the limiting member 7 is disposed on one side of the toothed plate 31. The limiting member 7 includes a slider 71 slidably connected to the side of the toothed plate 31, and a slide rod 72 slidably connected to the inner wall of the slider 71. The limiting member 7 also includes a second spring 73 sleeved on the surface of the slide rod 72, and there are two sliders 71, two slide rods 72 and two springs 73. The limiting member 7 also includes a toothed block 74 fixedly connected to the bottom of the slider 71, and the top of the toothed block 74 is slidably connected to the bottom of the toothed plate 31.

[0024] The slider 71, the slide bar 72, and the second spring 73 on the same side form a group. The two groups are respectively set on both sides of the toothed plate 31 and are used to support the same toothed block 74. When the grease falls off, the first gear 44 is prone to jamming the toothed plate 31. When the first gear 44 rotates to the surface of the toothed block 74, it can drive the toothed block 74 to slide towards the teeth on the surface of the toothed plate 31. At this time, it will put pressure on the second spring 73. When the second spring 73 resets, it drives the slider 71 to reset and at the same time drives the toothed block 74 to reset, so that the first gear 44 continues to mesh with the toothed block 74, preventing the first gear 44 from jamming the toothed plate 31. The coefficient of the second spring 73 is 0.5~3N / mm.

[0025] Working principle: When the vehicle control device issues a locking command, the external power supply powers the motor 32 through power line 2. The output of the motor 32 drives the first bevel gear 41 to rotate, and simultaneously drives the first gear 44 to rotate synchronously, pushing the gear plate 31 and locking rod 33 to move towards the charging interface latch, inserting into the locking position to complete the physical locking. When unlocking, the motor 32 reverses and drives the first gear 44 to rotate counterclockwise, pulling the gear plate 31 away from the locking target. The locking rod 33 retracts, releasing the lock. When the first gear 44 rotates to the position of the tooth block 74, the tooth block 74 slides towards the gear plate 31 under the thrust of the gear teeth, while simultaneously compressing the second spring 73 sleeved on the slide rod 72. After the gear teeth pass the tooth block 74, the second spring 73 resets, pushing the slider 71 and the tooth block 74 back to their original positions, preventing damage from lubricant shedding or minor damage to the tooth surface. Wear and tear can cause jamming. To ensure smooth transmission, when motor 32 malfunctions, the operator rotates the turntable 68 on the side of positioning box 61, which drives the second gear 64 to rotate. This, in turn, drives the gear ring 63 and the coil 62 to rotate, starting to wind and collect the steel rope 51. This pulls the limit block 52, which in turn drives the toothed plate 31 to slide backward, completing the unlocking process. During the rope winding process, the first spring 66 provides elasticity to the limit plate 65, ensuring that the limit plate 65 always fits against the teeth of the gear ring 63, preventing the coil 62 from rotating in the opposite direction due to the tension of the steel rope 51. This ensures the stable winding and unwinding of the steel rope 51. When the electronic function is restored, the lever 67 is moved to disengage the limit plate 65 from the gear ring 63. When motor 32 drives the toothed plate 31 to slide forward, the limit block 52 pulls the steel rope 51, causing the coil 62 to rotate in the opposite direction. The steel rope 51 is released again until the toothed plate 31 is reset, preparing for the next emergency unlocking.
