[0024] See also Figure 1-4 A switchable vehicle alarm includes an alarm body 1, a controller 4 is fixedly connected to the left side of the alarm body 1, and the controller 4 is electrically connected to the alarm body 1.

[0025] Furthermore, the controller 4 can control the volume of the alarm 1 when it is switched to use as needed, and the control circuit can be realized by simple programming by technicians in this field, which belongs to the common knowledge in this field and will not be elaborated here.

[0026] The mounting shell 11 is arranged at the bottom of the alarm body 1, and mounting plates are fixedly connected to the bottoms of the left and right sides of the mounting shell 11, and mounting holes are opened on the left and right sides of the top of the mounting plate, through which the mounting plate can be conveniently mounted on the vehicle body.

[0027] The buffer shock absorbing mechanism 2 is arranged inside the mounting shell 11. The buffer shock absorbing mechanism 2 includes a movable plate 21. The movable plate 21 slides in contact with the inner wall of the mounting shell 11. The left and right sides of the bottom of the movable plate 21 are fixedly connected with inclined blocks 22. The bottom of the inner wall of the mounting shell 11 and the left and right sides of the inclined blocks 22 are fixedly connected with fixed blocks 23. Two fixed blocks 23 on the same side and the opposite side are fixedly connected with two positioning rods 24. The surfaces of the two positioning rods 24 on the same side are in sliding contact through the moving block 25. The two side positioning rods 24 are fixedly connected by a baffle 26 on the side away from the fixed block 23, and a buffer spring 27 is sleeved on the surface of the positioning rod 24. A movable block 28 is fixedly connected to the side of the movable block 25 close to the inclined block 22. A ball 29 is movably connected in a groove of the movable block 28 close to the side of the inclined block 22. One end of the ball 29 close to the inclined block 22 is in rolling contact with the inclined block 22. A shock absorber 210 is fixedly connected in the groove at the bottom of the inner wall of the mounting shell 11 and at the position corresponding to the inclined block 22, and the top of the shock absorber 210 is fixedly connected to the bottom of the inclined block 22.

[0028] Through the mutual cooperation of the movable plate 21, the inclined block 22, the fixed block 23, the positioning rod 24, the moving block 25, the baffle 26, the buffer spring 27, the movable block 28, the ball 29 and the shock absorber 210, when the vehicle body vibrates during operation, a rigid collision between the alarm and the vehicle body is avoided, so that the alarm has a buffering effect, thereby avoiding damage to the alarm caused by long-term continuous rigid vibration, thereby avoiding affecting the service life of the alarm.

[0029] The connecting mechanism 3 is arranged at the bottom of the alarm body 1, and the connecting mechanism 3 includes a base 31. The base 31 is installed at the bottom of the alarm body 1 and is located at the top of the movable plate 21. The bottom of the base 31 is in contact with the top of the movable plate 21, and the left and right sides of the top of the base 31 are provided with fastening bolts 32 threadedly connected to the movable plate 21.

[0030] Furthermore, by loosening the fastening bolts 32 , the base 31 and the movable plate 21 can be separated.

[0031] When in use, when the vibration generated by the vehicle body during operation is transmitted to the mounting shell 11, the movable plate 21 drives the inclined block 22 to move downward, and the inclined block 22 drives the movable block 28 and the moving block 25 to move close to the fixed block 23 through the ball 29, so that the moving block 25 squeezes the buffer spring 27 to move, and at the same time, the inclined block 22 squeezes the shock absorber 210 downward to move, and the vibration transmitted from the vehicle body can be effectively offset by the elastic force of the buffer spring 27 and the shock absorber 210.

[0032] In summary: the switchable vehicle alarm solves the problems raised in the above-mentioned background technology through the mutual cooperation of the movable plate 21, the inclined block 22, the fixed block 23, the positioning rod 24, the moving block 25, the baffle 26, the buffer spring 27, the movable block 28, the ball 29 and the shock absorber 210.
