Description
Technical field
The utility model belongs to motor vehicle apparatus technical field, relates in particular to a kind of motor vehicle speed indicator.
Background technology
China Shi Yige motor vehicle big country, particularly automobile.Along with the raising of people's living standard, and corresponding vehicle fleet size surges, and people is many, car is many, technology, reaction, operation etc. are also brought different difference, thereby has caused traffic hazard also to increase accordingly, and wherein major part is because rear-end collision causes.Owing to causing damage to the velocity estimation of front truck vehicle is inaccurate, particularly, in cloudy day or rainy day, the risk that knocks into the back is larger.
Summary of the invention
The purpose of this utility model is to solve above-described technical matters, and a kind of motor vehicle speed indicator that can see in real time front truck travel speed is provided, and its technical scheme is as follows:
A kind of motor vehicle speed indicator, it is characterized in that, described motor vehicle speed indicator comprises shell, in described shell, be provided with mechanical separator speed conversion signalling device, described mechanical separator speed conversion signalling device is connected with circuit board, and described circuit board is connected with Speed display LED board, and Speed display LED board is arranged on a lateral surface of shell, in described shell, be provided with battery, described battery is connected with circuit board.
The motor vehicle speed indicator that the utility model provides, is provided with mechanical separator speed conversion signalling device in described shell, be that the real time running rate conversion of automobile is become to digital signal, then digital data transmission is being shown to Speed display LED board.Speed display LED board is comprised of luminous plaque, when signal being input to after circuit board to display speed numeral on luminous plaque by mechanical separator speed conversion signalling device, thereby can see the travel speed of front truck to trailer.Rear car just can accomplish to know what's what, can take appropriate measures in advance, thus lower generation of knocking into the back.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Below in conjunction with Fig. 1, illustrate embodiment:
As described in Figure 1, a kind of motor vehicle speed indicator, described motor vehicle speed indicator comprises shell 1, in described shell 1, be provided with mechanical separator speed conversion signalling device 2, described mechanical separator speed conversion signalling device 2 is connected with circuit board 3, and described circuit board 3 is connected with Speed display LED board 4, and Speed display LED board 4 is arranged on a lateral surface of shell 1, in described shell 1, be provided with battery 5, described battery 5 is connected with circuit board 3.
Battery can be to use dry cell, can be also with car in cigar lighter in connect vehicle power be provided.And mechanical separator speed conversion signalling device can be bound with satnav, adopt satellite-signal to transform.Then digital data transmission is being shown to Speed display LED board.Speed display LED board is comprised of luminous plaque, when signal being input to after circuit board to display speed numeral on luminous plaque by mechanical separator speed conversion signalling device, thereby can see the travel speed of front truck to trailer.Rear car just can accomplish to know what's what, can take appropriate measures in advance, thus lower generation of knocking into the back.
When in use, this device is arranged at the afterbody of car.
