Description

Technical Field

[0001] The utility model relates to the technical field of automobile gear levers, in particular to a non-power-supply luminous gear lever and a driving circuit thereof. Background Art

[0002] The car barrier is also called an octagonal bar. It is used at parking lot entrances and exits, highway toll booths, community entrances, highway toll gates, etc. It serves as a public transportation tool to restrict vehicle traffic. For the use of existing parking spaces, parking spaces are easily occupied by non-parking vehicles. To solve this problem, a gate device with a folding wall can be placed directly behind the parking space. The front end of the folding wall is connected in a "T" shape to a barrier bar about 1 meter long and 0.1 meter wide to block the parking space. The existing parking barrier bars are usually made of aluminum alloy. In order to increase visibility at night, a lighting lamp is installed under the parking barrier bar and connected to a power supply.

[0036] According to one embodiment of the present invention, Figure 1-Figure 9 Shown.

[0038] Specifically, the specific model of the solar panel is DJB_12_3 (open circuit voltage 12.77V, power 3W), the specific model of the lighting lamp is 4010 (rated voltage 12V, rated power 1W), the specific model of the ultrasonic probe is GU16B01L01-A17, the specific signal of the radar analyzer is PGR_120304S, and the ultrasonic probe includes four groups.

[0039] Similarly, contact dampers are fixed at both ends of the bottom of the baffle bar panel. A mounting hole is provided on the baffle bar rear cover, and the lighting controller and the radar analyzer are correspondingly arranged in the mounting hole, and the mounting hole is sealed and fixed by a mounting hole cover plate and a first sealing gasket. A hinge seat is provided at the connection between the baffle plate and the front bar, and the hinge seat is sealed and fixed to the front bar by a second sealing gasket.

[0040] The lighting lamp is used to enhance the brightness under the barrier bar; the solar panel is used to absorb solar energy and convert it into electrical energy and store it, thereby supplying power to the radar analyzer and the lighting controller; the radar analyzer is used to receive waveform data from the ultrasonic probe and provide power support to the ultrasonic probe; the lighting controller is used to supply power to the lighting lamp and control the turning on and off of the lighting lamp according to the external brightness; the mounting hole cover is used to install and remove the radar analyzer and the lighting controller; the first sealing gasket and the second sealing gasket are used to seal and ensure the waterproofness of the barrier bar.

[0041] Through the above structure, the front bar can block the vehicle, and the hollow column structure composed of the bar rear cover and the bar panel that are relatively arranged and spliced ​​into an integral body can provide the necessary hinge effect of the front bar. At the same time, a lighting controller and a radar analyzer are built-in to cooperate with the lighting and ultrasonic probe on the bar panel to perform detection operations. The contact damping is designed to avoid hard contact between the bar and the object. The damping can effectively absorb the force generated by the touch and reduce damage.

At the same time, the solar charging circuit will store the electric energy in the lithium battery during the day. Here, the lithium battery is the common battery of the whole device. The rated voltage in the circuit is 12V, and then it is connected to the power supply circuit for step-down output. 8V is used to supply the MCU, and 5V is used to supply the ultrasonic probe. At the same time, the MCU is connected to the external lighting through the pin P17 and the CN5 connector to realize the switching of the lighting at different times during the day and night.
