A device to quickly find a car in a huge parking lot.

Background technique

It is very common for modern people to use cars instead of vehicles. Due to the large number of cars, the plane parking spaces on the side of the road are very limited, so we have to turn to building indoor parking lots, regardless of whether it is a three-dimensional indoor parking lot or an underground parking lot. In order to meet the demand, its construction The large space is used to set up a large number of parking spaces. A single floor with large space can reach more than hundreds of pings. Although the design of this large-space parking lot can accommodate more vehicles, for car owners who park, the space is large. Finding a car can be very difficult.

Since there are many parking spaces and parked vehicles in the large indoor parking lot, it takes a certain amount of time for the owner to find his car, especially when the owner is not familiar with the environment of the parking lot or the light in the parking lot is not good. The car process is more time-consuming.

For this situation, the current commonly used solution is to start the car with the remote control key after the car owner enters the parking lot, so that the car will make a "beep, beep" sound, so that the car owner will prompt the approximate location of the car's parking position according to the sound. In this way, the scope of car search can be narrowed down, thereby shortening the search time. However, as most car owners know, once a sound is generated in the huge space of the indoor parking lot, it is very easy to cause an echo, which will affect the accuracy of the direction judgment.

Due to the large space and many vehicles, coupled with unfamiliarity with the environment, it may not be possible to quickly find a car in a short period of time, causing troubles. A positive solution is urgently needed to solve it.

Therefore, the main purpose of the present invention is to provide a car-finding auxiliary positioning device, which is installed in an appropriate position in the car, and can be driven by remote control to project a striking point of view or a pattern at an appropriate position around the parking place when searching for a car. , In this way, the car owner can quickly find his car in the huge parking lot.

In order to achieve the above object, the auxiliary positioning device for finding a car provided by the present invention includes a base, a control module disposed in the base, and a light emitter arranged on the base in an angle-adjustable manner; wherein:

The control module includes:

A wireless receiver, used to receive the remote control driving signal transmitted wirelessly;

A controller, the input end of which is connected to the output end of the wireless receiver, and the output end of the controller is connected with the optical transmitter.

The positioning device composed of the above structure can assist the owner to quickly find the car in the parking lot: since the light emitter is combined with the base in an adjustable angle (such as pivot joint), when the car enters the parking lot and stops at the predetermined position Finally, the angle of the light emitter can be adjusted so that it faces the projection target (such as the ceiling, high wall, etc.) near the parking space; when the car owner returns to the parking lot again, the remote control can transmit the driving signal, controlled by the After being received by the wireless receiver in the module, it is decoded and sent to the controller, and then the controller drives the light emitter to generate a light beam, and forms a significant light spot or pattern on the projected target, so that the light can be transmitted through the Guided by light spots or patterns, it helps car owners quickly find a car in a huge space and a crowd of cars.
