[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0021] See also Figure 1-5 , an embodiment provided by the utility model:

[0022] A transmission shaft fault alarm prompting device: comprises a support frame 1, a diagonal brace 11 is fixedly installed on the surface of the support frame 1, a travel switch 12 is fixedly connected on the surface of the support frame 1, a contact 13 is arranged on the surface of the travel switch 12, a conductive circuit 15 is arranged on the travel switch 12, power supplies 14 are arranged at both ends of the conductive circuit 15, a buzzer alarm 16 is arranged on the surface of the conductive circuit 15, and an adjustment mechanism is arranged on the surface of the support frame 1. The fault alarm prompting device can sound an alarm when the transmission shaft is deviated, thereby reminding the driver to inspect the vehicle, reduce safety hazards, and improve the safety of the vehicle.

[0023] Furthermore, the adjusting mechanism includes a slider 2, which is slidably connected to the surface of the support frame 1, one side of the slider 2 is fixedly connected to the mounting frame 21, the other side of the slider 2 is fixedly connected to the nut 22, the surface of the support frame 1 is fixedly connected to a fixing block 23, the surface of the fixing block 23 is rotatably connected to a screw rod 24, and the surface of the screw rod 24 is fixedly connected to a knob 25. The adjusting mechanism can adjust the height of the support frame 1, thereby changing the height of the travel switch 12 and the contact 13, thereby improving the adaptability of the fault alarm prompt device and facilitating the user to install the device.

[0024] Furthermore, the support frame 1 is in an "L" shape, the travel switch 12 is fixedly mounted on the top of the support frame 1, and the diagonal brace 11 on the support frame 1 strengthens the overall structural strength of the support frame 1 and ensures the stability of the position of the travel switch 12.

[0025] Furthermore, the horizontal height of the contact 13 is the same as the horizontal height of the transmission shaft, and the contact 13 and the transmission shaft are in contact and connected together. When the position of the transmission shaft is offset, the transmission shaft will open the travel switch 12 through the contact 13.

[0026] Furthermore, the travel switch 12 is in a normally closed state, the travel switch 12 and the buzzer alarm 16 are connected in series on the conductive circuit 15, the power supply 14 supplies power to the buzzer alarm 16 through the travel switch 12, the power supply 14 is an original internal device of the vehicle, and can be used after wiring. The buzzer alarm 16 is fixedly installed in a position close to the driver. When the buzzer alarm 16 sounds an alarm, it ensures that the driver can hear the alarm.

[0027] Furthermore, a guide hole is opened on the surface of the support frame 1, and the slider 2 slides in the guide hole of the support frame 1. The nut 22 and the mounting frame 21 synchronize the slider 2 to slide and rise and fall on the support frame 1. The mounting frame 21 is in an "L" shape, and a mounting hole is opened at the bottom of the mounting frame 21. The mounting frame 21 is installed on the vehicle through the mounting hole, and the mounting frame 21 supports the support frame 1 on the vehicle.

[0028] Furthermore, one end of the screw rod 24 away from the fixed block 23 rotates on the support frame 1, and the screw rod 24 is driven to rotate by the knob 25. The screw rod 24 drives the nut 22 to slide and rise and fall on the surface of the support frame 1 by rotation, and the nut 22 drives the mounting frame 21 to rise and fall on the support frame 1 through the slider 2. The lifting of the mounting frame 21 changes the relative position relationship between the mounting frame 21 and the support frame 1. The mounting frame 21 and the nut 22 limit the position of the slider 2 in the guide hole of the support frame 1, thereby ensuring the sliding stability of the slider 2, the mounting frame 21 and the nut 22. Then, the support frame 1 is fixedly installed on the vehicle through the mounting frame 21. The change in the positional relationship between the support frame 1 and the mounting frame 21 causes the horizontal height of the support frame 1 on the vehicle to change.

[0029] Working principle: When the center line of the transmission shaft is offset, the transmission shaft will touch the contact 13, so that the travel switch 12 is in the open state. At this time, the conductive circuit 15 is turned on, and the power supply 14 supplies power to the buzzer alarm 16 through the conductive circuit 15, so that the buzzer alarm 16 emits an alarm sound, reminding the driver that the transmission shaft may have a fault, and the driver should stop the car in time at an appropriate location for inspection to eliminate driving hazards.

[0030] Rotate the knob 25 at the bottom of the support frame 1, the knob 25 drives the screw rod 24 to rotate on the fixed block 23, the screw rod 24 drives the nut 22 to slide on the support frame 1 through the rotation, the nut 22 drives the mounting frame 21 to slide on the support frame 1 through the mounting frame 21, the lifting and lowering of the mounting frame 21 changes the relative position relationship with the support frame 1, so that the horizontal height of the support frame 1 on the vehicle is changed, which improves the adaptability of the fault alarm prompt device and facilitates the user to install the device.
