Description

car brake light

technical field

The utility model relates to the technical field of automobile devices, in particular to an automobile brake lamp which can effectively prevent automobile rear-end collision accidents.

Background technique

In the process of driving in the city or on the highway, the car in front often brakes, and the car behind cannot judge whether the car in front brakes lightly or suddenly, so there are many rear-end collisions caused by not clearly judging the brakes of the car in front ACCIDENT. In addition, in southern cities in winter, due to heavy fog, vehicles often turn on double flashing lights to prevent rear-end collisions or attract attention. However, when the double flashing lights are on, it does not indicate whether the rear car is stopped or moving, so there are often multiple rear-end collisions, mostly serious traffic accidents.

Utility model content

The technical problem to be solved by the utility model is to provide a car brake light, by using the brake light, the occurrence of rear-end collision accidents during braking and parking can be reduced, and the resolution of cars driving or stopped in the fog can be increased, and serious rear-end collisions can be reduced. Accidents occur, reducing the death rate of traffic accidents.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: a kind of automobile brake light, the said brake light is arranged on the tail of the automobile, it is characterized in that: it includes a control module and a display module, the speed signal acquisition device of the automobile and The signal input terminal of the control module is connected, and the display module is connected with the speed signal output terminal of the control module. The control module processes the speed signal collected by the speed signal acquisition device and outputs it to the display module for display.

A further preferred technical solution is that: the display module is a digital tube matrix display.

A further preferred technical solution is that: the digital tube matrix display is a red LED matrix display.

A further preferred technical solution is that: the display of the nixie tube matrix display screen is five digits, which are respectively hundreds, tens, ones, decimal point and tenths.

A further preferred technical solution is that: the display module is a projection device, the lens of the projection device is set opposite to the rear windshield of the car, and the projected numbers are displayed on the rear windshield.

The beneficial effect of adopting the above technical solution is that the brake light can display the speed of the vehicle, prompting the speed of the speed of the vehicle in front of the rear vehicle after braking, which plays a warning role and reduces the probability of rear-end collision accidents. When driving on a foggy expressway, due to the large display range and high brightness of the matrix, the vehicle speed is displayed in digital form, and the prompt effect is more obvious. When parking, the prompt is a flashing stop state, that is, the red STOP sign, which reduces the time for the vehicle behind to determine the driving situation of the vehicle in front, and reduces the probability of serious rear-end collision accidents. Easy to install, convenient for car owners to install by themselves, or cooperate with car companies to integrate this brake light into the rear of the car when designing the car, which is beautiful and convenient, and is part of the audit content of the car safety standard.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

Fig. 1 is a block diagram of the utility model;

Among them: 1. Control module 2. Display module 3. Speed signal acquisition device.

Detailed ways

Below in conjunction with the accompanying drawings in the utility model embodiment, the technical solution in the utility model embodiment is clearly and completely described, obviously, the described embodiment is only a part of the utility model embodiment, rather than all implementation example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

In the following description, a lot of specific details have been set forth in order to fully understand the utility model, but the utility model can also be implemented in other ways that are different from those described here, and those skilled in the art can do so without violating the connotation of the utility model. Under the circumstances, similar promotion is done, so the utility model is not limited by the specific embodiments disclosed below.

As shown in FIG. 1 , the utility model discloses an automobile brake light, which is arranged at the rear of the automobile and includes a control module 1 and a display module 2 . The speed signal acquisition device 3 of the automobile is connected with the signal input end of the control module 1, and the display module 2 is connected with the speed signal output end of the control module 1, and the control module 1 outputs the speed signal collected by the speed signal acquisition device 3 after processing Show the display module 2; when the driver stepped on the brake, the display module 2 displayed the change of the speed of the car in digital form in real time; when the driver did not step on the brake and drove normally, the display module 2 had no speed display; when the car was stopped state, the display module 2 displays a stop sign. Further, when the speed drops to 0 km/h, the display module displays the STOP logo, prompting the car behind that this car is in a stopped state, and the double flashing function is turned on in the stopped state, except that the left and right turn lights of the car flash simultaneously, the STOP logo and the turn signal flashes synchronously.

There are two display modes of the display module: one is a red LED matrix display, and the display of the red LED matrix display is five digits, which are respectively hundreds, tens, ones, decimal point and tenths, The advantages are high brightness, strong penetrating power, and extremely low power; another kind of projection device, the lens of the projection device is set opposite to the rear windshield of the car, and the projected red numbers are displayed on the rear windshield. Stick the film, install and fix it in the car and project it to the rear window.

The brake light can display the speed of the vehicle, prompting the speed of the speed of the rear vehicle and the vehicle in front after braking, which plays a warning role and reduces the probability of rear-end collision accidents. When driving on a foggy expressway, due to the large display range and high brightness of the matrix, the vehicle speed is displayed in digital form, and the prompt effect is more obvious. When parking, the prompt is a flashing stop state, that is, the red STOP sign, which reduces the time for the vehicle behind to determine the driving situation of the vehicle in front, and reduces the probability of serious rear-end collision accidents. Easy to install, convenient for car owners to install by themselves, or cooperate with car companies to integrate this brake light into the rear of the car when designing the car, which is beautiful and convenient, and is part of the audit content of the car safety standard.
