[0018] Reference Figures 1 to 4 As shown, the utility model provides an anti-theft electric vehicle alarm device, comprising: an electric vehicle anti-theft alarm 1, the front end of which is connected to the electric vehicle controller circuit through a wiring terminal 11,

[0019] The lower end of the electric vehicle anti-theft alarm 1 is connected to the mounting bottom frame 2 through the connecting bottom plate 21, and a sensing plate 26 is supported in the groove of the mounting bottom frame 2 by a spring 23. A micro vibrator 27 is installed on the lower surface of the sensing plate 26. Vibration transmission plates 3 are symmetrically fixed on both sides of the upper surface of the electric vehicle anti-theft alarm 1. A stop column 43 is inserted and fitted at the front end of the vibration transmission plate 3 through a positioning hole 32. The front end of the stop column 43 is connected to a small electric push rod 41 through a limit plate 44. The small electric push rod 41 is fixed at the front surface of the limit slot block 4.

[0020] Working principle: The electric vehicle anti-theft alarm 1 is installed in the vehicle seat through the installation bottom frame 2. After the electric vehicle is powered off, the electric vehicle anti-theft alarm 1 is activated. The vibration generated when the external force moves the electric vehicle causes the vibration transmission plate 3 to vibrate slightly, so that the sensing plate 26 senses the vibration and activates the micro vibrator 27, thereby increasing the vibration intensity of the electric vehicle anti-theft alarm 1. The electric vehicle anti-theft alarm 1 immediately turns on the anti-theft alarm. When the electric vehicle is powered on, the small electric push rod 24 pushes the electric vehicle anti-theft alarm 1 upward, so that the vibration transmission plate 3 moves upward. During this process, the small electric push rod 24 pushes the stop column 43 to be inserted into the positioning hole 32 on the surface of the vibration transmission plate 3. When the contact sensor 42 senses that the stop column 43 is inserted into the vibration transmission plate 3, the sensor of the sensing plate 26 is turned off to avoid issuing an alarm signal during normal driving.

[0021] In this embodiment, an alarm sound tube 12 and a battery compartment 13 are provided on the upper surface of the electric vehicle anti-theft alarm 1 , and the lower surface of the vibration transmission plate 3 is in contact with the upper surface of the electric vehicle anti-theft alarm 1 via a rubber spacer 31 .

[0022] As a preferred embodiment, the alarm sound tube 12 plays an alarm role. The vibration transmission plate 3 is enhanced by the vibration, which makes it easier for the electric vehicle anti-theft alarm device 1 to sense the vibration more sensitively and generate an anti-theft alarm signal.

[0023] In this embodiment, the lower end of the vibration transmission plate 3 is limitedly connected in the groove of the mounting base frame 2; and the sensing plate 26 is distributed below the vibration transmission plate 3, the front end of the mounting base frame 2 is screwed and fixed with the limited groove block 4, and the upper surface of the sensing plate 26 is embedded with a vibration sensor.

[0024] As a preferred embodiment, when the vibration transmission plate 3 stationary on the sensing plate 26 is vibrated, the vibration sensor on the surface of the sensing plate 26 first senses the vibration and activates the micro vibrator 27, thereby increasing the vibration amplitude of the vibration transmission plate 3.

[0025] In this embodiment, a slide groove 25 is provided on the inner frame surface of the mounting base frame 2, and the left and right ends of the connecting base plate 21 are slidably connected in the slide groove 25. A small electric push rod 24 is embedded and installed in the frame surface of the mounting base frame 2.

[0026] As a preferred embodiment, a small electric push rod 24 is used to assist in pushing up the electric vehicle anti-theft alarm 1, so that the vibration transmission plates 3 on both sides move up, thereby allowing the stop column 43 to be inserted into the hole of the vibration transmission plate 3.

[0027] In this embodiment, a buffer pad 22 is bonded to the upper frame surface of the mounting bottom frame 2 ; and the buffer pad 22 is located below the connecting bottom plate 21 , and a positioning hole 32 is opened on the front surface of the vibration transmission plate 3 .

[0028] As a preferred embodiment, the buffer pad 22 is convenient for reducing the impact force of the lowering of the connecting bottom plate 21. The positioning hole 32 on the front surface of the vibration transmission plate 3 is convenient for positioning the position of the vibration transmission plate 3 to prevent the elasticity of the spring 23 from causing the sensor plate 26 to trigger the alarm signal by mistake during normal driving.

[0029] In this embodiment, a contact sensor 42 is installed on the rear end surface of the stop column 43 ; the contact sensor 42 is in contact with the hole wall, and the limiting plate 44 is limitedly connected in the inner groove of the limiting groove block 4 .

[0030] As a preferred embodiment, the contact sensor 42 is convenient for sensing whether the stopper column 43 is correctly inserted into the positioning hole 32. The limit plate 44 is convenient for driving the stopper column 43 to enter and exit the inner groove of the limit groove block 4.

[0031] In this embodiment, the limiting groove block 4 , the small electric push rod 2 41 , the stopping column 43 and the limiting plate 44 constitute a stopping structure of the vibration transmission plate 3 .

[0032] As a preferred embodiment, the stop structure of the vibration transmission plate 3 facilitates positioning of the vibration transmission plate 3 in the electric vehicle during normal driving, so that the sensing plate 26 and the micro vibrator 27 are in a closed state, avoiding the issuance of an alarm signal during normal driving.

[0033] The anti-theft electric vehicle alarm device of the utility model can effectively solve the problem of the electric vehicle alarm device losing its sensitivity due to the aggravated damage of the transmission components subjected to stress for a long time, make the anti-theft warning of the anti-theft electric vehicle alarm device more sensitive, facilitate the positioning of the vibration transmission plate in the electric vehicle during normal driving, and improve the service life of the enhanced sensitivity anti-theft electric vehicle alarm device, and is suitable for anti-theft electric vehicle alarm devices.
