Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of automobile accessories, and in particular relates to a control device for a rear-seat flip screen of an automobile. Background Art
[0002] A car is a non-track-borne vehicle that is powered by power and has four or more wheels. It is mainly used to carry people or goods.
[0003] In the prior art, with the development of science and technology, the functions of automobiles are becoming more and more. Among them, many automobile companies have added screens to the cars for the riding experience of rear passengers, so that the rear passengers can have a better experience during the ride. In order to fold the screen when not in use and not affect the field of vision of the rear passengers, a flip screen has appeared. The flip screen can be unfolded when needed and needs to be folded when not needed. Although the existing rear flip screen of the car can flip the screen when in use, during the flipping process, the screen will not stop automatically when encountering an obstacle, which can easily cause damage to the screen and the motor, and it does not have a 0-point correction function, so it is easy to cause mechanical wear and position distortion caused by Hall loss. Therefore, we propose a control device for the rear flip screen of a car. Utility Model Content
[0004] The utility model aims to provide a control device for the rear flip screen of a car to solve the technical problems that the flip screen will not stop automatically when encountering an obstacle and does not have the function of 0-point correction, so as to achieve the purpose of automatically stopping when encountering an obstacle and adding the function of 0-point correction.
[0005] In order to solve the above technical problems, the utility model provides a control device for the rear flip screen of an automobile, including a control device body which is rectangular and embedded in the top of the rear seat of the automobile, a square control switch is installed on the front side of the control device body near the top, and a square storage groove is opened on the front side of the control device body near the center, and then a rectangular flip screen body is embedded in the storage groove, and then a cylindrical rotating shaft is installed at the bottom of the flip screen body and at the bottom of the storage groove, a drive motor is installed inside the control device body near the bottom on the left side, and a Hall sensor is installed on the right side of the drive motor, and then an angle sensor is installed inside the Hall sensor near the bottom on the right side.
[0006] Furthermore, a first dustproof and heat dissipation net is symmetrically installed on the back of the flip screen body, and a central processing unit is installed inside the flip screen body.
[0007] Furthermore, a receiving groove is provided on the periphery of the driving motor and inside the control device body, and a second dustproof and heat dissipating net is clamped on the front of the receiving groove.
[0008] Furthermore, cylindrical connecting shafts are installed on both sides of the rotating shaft, and rotating bearings are installed on the periphery of the connecting shaft and inside the control device body. The connecting shaft on the left is fixedly connected to the output end of the drive motor, and the connecting shaft on the right is fixedly connected to the angle sensor.
[0009] Furthermore, a PTC thermistor is installed on the right side of the drive motor, and the PTC thermistor is electrically connected to the drive motor.
[0010] Through the above technical solution, the PTC thermistor can effectively detect whether the temperature of the drive motor rises, thereby effectively transmitting the parameters to the central processor, and the central processor controls the drive motor to stop running, thereby ensuring that the motor does not overheat.
[0011] Furthermore, the central processing unit supports a CAN online upgrade function, the central processing unit has a UDS diagnostic function, and the central processing unit has an electronic lock control function.
[0012] Furthermore, the central processing unit has a switch anti-playing function, and the central processing unit is electrically connected to the drive motor, the Hall sensor, the angle sensor, and the PTC thermistor.
[0013] The beneficial effects of the utility model are:
[0014] 1. In the utility model, through the setting of the Hall sensor, the Hall sensor will monitor the rotation speed of the drive motor. When the flip screen body encounters an obstacle when opening or closing, the rotation speed of the drive motor will drop below the set limit, and the Hall sensor detects the existence of the obstacle. When the Hall sensor detects the existence of the obstacle, it transmits the parameters to the central processing unit, and the central processing unit controls the drive motor to stop rotating, thereby avoiding the flip screen body from continuing to open and close and causing damage to itself and wear of the drive motor. The PTC thermistor can detect whether the drive motor is overheated, thereby effectively transmitting the parameters to the central processing unit, and the central processing unit stops the drive motor that is about to overheat to avoid it from overheating.
[0015] 2. In the utility model, through the setting of the angle sensor, the angle sensor can effectively detect the rotation angle of the rotating shaft and the connecting shaft, so that when the driving motor drives the connecting shaft and the rotating shaft to rotate and reaches the set angle, the angle sensor sends a signal to the central processing unit, and the central processing unit will control the driving motor to stop driving. When the flip screen body is pulled and the angle deviates from the set angle, the angle sensor also sends an angle signal to the central processing unit. At this time, the central processing unit will drive the driving motor to work and perform 0-point correction on the flip screen body and the rotating shaft.
