About the vehicle-mounted TV lifter
When traveling or on business trips, people often like to watch vehicle-mounted TV programs to pass the time. In traditional vehicles, such as buses, vehicle-mounted TVs are exposed in the interior. It is usually installed in the front of the car. However, people, especially drivers, need to be careful to tilt their heads down to avoid hitting the TV. To meet the needs of the rear passengers, a vehicle-mounted TV lifter that can not only view the specific situation in front of the vehicle but also can be raised and lowered came into being.
The elevator of a vehicle-mounted TV includes a base fixed to the vehicle; a ball screw fixed to the pedestal; a motor whose output end is connected to the ball screw through a coupling; and the lifting driven by the ball screw Rack, which is used to fix the TV. When the TV needs to be used, the motor drives the lifting frame through the ball screw to lift the TV.
When it reaches the predetermined position, the limit opening sends a signal to the electric motor, and the motor stops working; when the TV is not needed, the electric motor passes through the ball screw. The lifting frame is driven to drive the TV down, to bring the TV into the preset groove of the car wall to save the real space in the compartment. It not only improves the efficiency of using the car space but also makes the carriage more beautiful.
How the TV lifter works
The vehicle-mounted TV lifter structure includes a lifting bracket assembly and a gear shaft fixing assembly. The vehicle-mounted TV is fixed on the TV fixing plate, and the TV fixing plate is fixedly connected to the gear shaft fixing assembly. The inner left and right sides of the lifting bracket assembly are provided with a vertical The rack and pinion shaft are fixed inside the lifting bracket assembly through the pinion shaft fixing assembly.
There is a spur gear on the left and right sides of the gear shaft. The spur gears are connected to the rack. The DC reduction motor drives the gear shaft to rotate, and the gear shaft is fixed. When the component touches the upper contact micro switch or the lower contact micro switch, the DC decelerating motor is powered off, and the vehicle-mounted TV stops rising or falling.
The structure is simple, and the operation is convenient; it is equipped with a linear guide rail and a linear slide block, which limits only linear sliding, thus achieving the purpose of linear lifting; its automation is strong; two DC electromagnetic brakes are installed to increase stability and safety.
The TV control box is connected with the motor and the limit switch. The left and right sides of the TV fixing frame are fixed with sliding plates while the right sliding plate is fixed with a sliding frame. The upper and lower ends of the sliding frame are fixed with rollers, and the rollers are stuck in the rolling groove. The rollers on the left and right sides of the TV fixing frame roll in the chute. The TV fixing frame as a whole moves up and down in the outer frame through rollers, and the movement is stable. The integrated structure of the TV and TV rack is more stable.
The operation of a car TV lifter is closely related to the motor, and the source of its life is the motor.
