DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See attached Figure 1-8 An electric vehicle ignition switch with an anti-theft function comprises a switch body 1, a rotary cover 2 for covering a switch opening is rotatably connected to the top of the switch body 1, the rotary cover 2 can cover the switch opening to prevent dust from entering, a fixed column 21 is slidably connected inside the rotary cover 2, a limiting plate 211 is provided on the outer wall of the fixed column 21, and the top of the limiting plate 211 is connected to the bottom of the rotary cover 2 through a first spring 213;

[0031] A card plate 22 that cooperates with the fixing column 21 is provided at the bottom of the rotary cover 2, and the inclined surface of the card plate 22 abuts against the bottom of the limit plate 211. A fixing hole 11 that cooperates with the fixing column 21 is opened at the top of the switch body 1. The rotary cover 2 is rotated so that the rotary cover 2 completely covers the top of the switch body 1, and then the fixing column 21 is pressed. At this time, the fixing column 21 drives the limit plate 211 to move downward and push the card plate 22. When the limit plate 211 moves to the bottom of the card plate 22, the card plate 22 elastically resets and abuts against the top of the limit plate 211. At this time, the fixing column 21 cannot bounce upward, and the bottom of the fixing column 21 is inserted into the fixing hole 11. At this time, the rotary cover 2 is locked at the top of the switch body 1, which plays an anti-theft role.

[0032] In this embodiment, a slide groove 222 along the slide rail 221 is opened in the card plate 22, and the slide rail 221 is fixed to the bottom of the rotary cover 2. One side of the slide rail 221 is connected to the inner wall of the slide groove 222 through the second spring 223. When the fixed column 21 drives the limiting plate 211 to move downward and pushes the card plate 22, the card plate 22 moves along the slide rail 221 and compresses the first spring 213. When the limiting plate 211 moves to the bottom of the card plate 22, under the reset elastic force of the first spring 213, the card plate 22 elastically resets and is stuck to the top of the limiting plate 211, thereby completing the limitation of the fixed column 21.

[0033] In this embodiment, a square hole 214 is provided at the bottom of the fixing column 21, and a block 12 matching the square hole 214 is provided in the fixing hole 11. When the fixing column 21 is found in the fixing hole 11 for locking, the block 12 is relatively inserted into the square hole 214. At this time, the block 12 will limit the fixing column 21 to avoid the fixing column 21 driving the limiting plate 211 to deflect away from the bottom of the card plate 22 by simply rotating the fixing column 21, and then the fixing column 21 is driven by the first spring 213 to pop out of the fixing hole 11, causing the lock between the rotary cover 2 and the switch body 1 to be opened, thereby improving the anti-theft effect.

[0034] In this embodiment, a reset rod 23 is slidably connected inside the rotary cover 2. The reset rod 23 extends to one side of the bottom of the rotary cover 2 and abuts against the inclined surface of the clamping plate 22. The top of the reset rod 23 is connected to the top of the rotary cover 2 through the third spring 231. The reset rod 23 is pressed. At this time, the reset rod 23 moves downward and pushes the clamping plate 22 to move. At this time, the clamping plate 22 is away from the limiting plate 211 and is no longer limited. At this time, the fixed column 21 is reset upward under the action of the first spring 213. At this time, the rotary cover 2 can be unscrewed, which is convenient for the driver to insert the key into the switch port of the switch body 1.

[0035] In this embodiment, the outer wall of the reset rod 23 is provided with a plurality of limit plates 232, and the top of the rotary cover 2 is provided with a plurality of code disks 24. The code disk 24 extends to one side of the bottom of the rotary cover 2 and is connected to a limit plate 241. The top of the limit plate 241 abuts against the bottom of the limit plate 232. An unlocking groove 242 for the passage of the limit plate 232 is opened in the limit plate 241. The limit plate 241 abuts under the limit plate 232. At this time, the reset rod 23 cannot be pressed downward, and the code disk 24 is rotated so that the unlocking groove 242 is aligned with the limit plate 232. At this time, the reset rod 23 can move downward, and the card plate 22 can be pushed, thereby unlocking the rotary cover 2 relative to the switch body 1. Only by entering the correct password can the rotary cover 2 be unlocked relative to the switch body 1, which greatly improves the anti-theft effect.

[0036] In this embodiment, a mark is provided on the circumference of the code disk 24 to facilitate forming a code mark.

[0037] In this embodiment, the slide rail 221 is divided into an upper plate and a lower plate, wherein the upper plate is arranged in the slide groove 222, the width of the lower plate is greater than the width inside the slide groove 222, and the top of the lower plate abuts against the bottom of the card plate 22 to facilitate the movement of the card plate 22 along the slide rail 221.

[0038] In this embodiment, an arc-shaped spring piece 25 is provided at the bottom of the rotary cover 2, and a groove 13 matching the arc-shaped spring piece 25 is provided at the top of the switch body 1. When the rotary cover 2 is fully rotated to the top of the switch body 1, the arc-shaped spring piece 25 is stuck in the groove 13, so that the rotary cover 2 is completely aligned with the switch body 1.

[0039] Working principle: the rotary cover 2 is rotated to the top of the switch body 1 , and the rotary cover 2 is completely covered on the switch body 1 through the cooperation between the arc-shaped spring piece 25 and the groove 13 .

[0040] The fixing column 21 is pressed so that the bottom of the fixing column 21 is inserted into the fixing hole 11. At this time, the clamping plate 22 is clamped on the limiting plate 211, so that the fixing column 21 cannot rebound upward. At this time, the switch body 1 and the rotary cover 2 are locked, thereby achieving an anti-theft effect.

[0041] The code disk 24 is rotated to align the unlocking slot 242 with the limiting plate 232. At this time, the reset rod 23 is pressed to move the card plate 22 away from the top of the limiting plate 211. At this time, the fixing column 21 is reset upward under the action of the first spring 213. At this time, the lock between the switch body 1 and the rotary cover 2 is released. The lock can only be released by entering the correct code, which greatly improves the anti-theft effect.
