Technical Field

[0001] The invention relates to the technical field of vehicle speed reminders, in particular to a vehicle speed reminder capable of reminding a following vehicle of the vehicle speed. Background Art

[0002] On highways, vehicles usually travel at a high speed. If the vehicle in front suddenly slows down or stops, the vehicle behind may not be able to slow down or avoid it in time and may rear-end it. This is especially true when driving at a snail's pace in the overtaking lane, which is more likely to cause a rear-end collision.

[0003] Existing speed reminders are generally installed on the center console of the car and are usually used to assist the driver. When driving on the highway, when the speed is too high or too low, it will make a "ding" sound to remind the driver to reduce or speed up. However, it does not have the function of reminding the driver of the following vehicle. The rear vehicle is not clear about the speed of the front vehicle, and the driver cannot adjust his speed in time, which may cause the distance to the front vehicle to be too close, resulting in a rear-end collision, and it is impossible to respond faster, such as emergency braking or avoidance, which increases the occurrence of accidents.

[0004] Therefore, the present invention designs a vehicle speed reminder, which can display the vehicle speed at the rear window of the vehicle, so that the rear driver can know the speed of the front vehicle, so as to solve the problems existing in the prior art. Summary of the invention

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention uses 3M glue to bond the U-shaped frame to the rear window position in the car to fix the speed display screen. When the vehicle is driving on the highway, the storage motor drives the rotating shaft to rotate 90 degrees, so that the speed display screen stands upright toward the rear window. The speed display screen displays the speed of the vehicle, which is convenient for the driver of the rear vehicle to know the speed of the front vehicle. The driver can adjust his speed in time to avoid being too close to the front vehicle, thereby effectively preventing the occurrence of rear-end collision accidents. If the front vehicle suddenly slows down or stops, knowing its speed can help the driver to react faster, such as emergency braking or avoidance, reducing the possibility of accidents.

[0015] 2. The present invention can adjust the inclination angle of the wiping component and the heating component by adjusting the angle component, so as to facilitate matching rear windows with different inclination angles. The lateral movement component drives the wiping sponge, the nozzle and the cleaning brush to move. The wiping sponge wipes the mist on the inner wall of the rear window. The hot air sprayed by the nozzle can dry the raindrops on the outer wall of the window and the residual mist on the inner wall, so as to avoid the influence of the fogged window or the residual raindrops on the rain on the speed display screen on the rear vehicle driver's viewing. The cleaning brush can wipe the dust on the speed display screen to reduce the adhesion of dust to the speed display screen.

[0016] 3. The present invention arranges a wiping component and a heating component. When the wiping sponge absorbs moisture from wiping mist and becomes moist, driving motor one drives rotating bar one to rotate 90 degrees, and driving motor two drives rotating bar two to rotate 90 degrees, so that the wiping sponge and the nozzle face each other, and then the nozzle sprays hot air to dry the wiping sponge, thereby reducing the possibility of the wiping sponge becoming moldy due to moisture.

[0031] Working principle: The U-shaped frame 401 is bonded to the rear window position inside the car through 3M glue 404. The vehicle-mounted GPS speed measuring device and the speaker are installed in the equipment box 1, and are linearly connected to the speed display screen 3. The speed of the vehicle can be displayed on the speed display screen 3. When the car is about to drive on the highway, the storage motor 403 drives the shaft 402 to rotate 90 degrees, so that the installation frame 2 stands upright, and the speed display screen 3 can stand upright and face the rear window. The rear vehicle can know the speed of the front vehicle through the speed display screen 3, thereby improving the safety of driving on the highway. At the same time, when the speed is too high or too low, a sound is emitted through the speaker to remind the driver of the vehicle to speed up or slow down. Before driving on the highway, if the rear window of the vehicle is When the inner wall is fogged or there are raindrops remaining on the outer wall of the rear window, it may affect the clarity of the speed display screen 3 observed by the driver of the rear vehicle. According to the inclination angle of the rear window, the worm 704 is first rotated to drive the worm wheel 705 to rotate, so that the adjustment shaft 702 drives the T-shaped rotating block 703 to rotate, and the wiping sponge 806 and the nozzle 904 are tilted to the same angle as the rear window. The electric cylinder 803 drives the mounting strip 804 to extend, so that the wiping sponge 806 is in close contact with the inner wall of the rear window, and then the transverse motor 603 is started to rotate the long screw rod 602, driving the slide plate 5 to move back and forth, and the wiping sponge 806 can wipe the inner wall of the rear window. At the same time, the air pump 905 is started, and a heating tube 906 is provided with a heating The hot air enters the air pipe 903 through the hose 907 and is then ejected through the nozzle 904 to heat the vehicle window, so that the raindrops on the outside of the vehicle window and the residual mist on the inner wall of the vehicle window can be dried. After the raindrops and the mist evaporate, the driver of the rear vehicle can view the values ​​on the speed display screen 3 more clearly. When the slide plate 5 moves, it drives the cleaning brush 105 to move. The cleaning brush 105 can wipe the surface of the speed display screen 3 to reduce dust on the speed display screen 3 and improve the display effect of the speed display screen 3, further allowing the driver of the rear vehicle to view the values ​​on the speed display screen 3 more clearly.
