(3) The rain-proof and sun-proof structure; the drive mechanism composed of 24V DC geared motor; the box structure with streamline design; the control mechanism composed of control unit, angle sensor and photoelectric proximity switch (1); Control switch Integrated control switch.

Under the weather conditions that need to use the device of the present invention, the driver will turn ON the control switch of the device integrated on the control switch of the passenger car door, and the device is in an active state. During the signal of the switch, the expansion edge (2) of the driving motor pulls the rain-shielding and sun-proof structure along the counterclockwise direction (overlooking), and the motor shaft (5) rotates. The rainproof cloth (6) is subjected to the traction of the unfolded edge (2) of the rain-shielding and sun-proof structure, and under the guiding action of the guide ring A (8) and the guide ring B (9), it is launched in the counterclockwise direction.

During the unfolding process of the rain-proof and sun-proof structure, the angle sensor continuously measures the unfolding angle of the device, and the control unit controls the motor to stop rotating after reaching the prescribed unfolding angle. At this time, the rain-shielding and sun-proof structure plays the function of rain-shielding and sun-shielding. The guide ring A (8) and the guide ring B (9) limit the rotation of the umbrella rib (7) in the vertical direction while ensuring the correct deployment and accurate return of the rainproof cloth (6), so that the rain-proof and sun-proof structure has a certain of wind resistance.

After all the passengers enter the car, the driver presses the door control switch, and the control unit controls the motor to reversely rotate after collecting the folding chair command, and retracts the rain-shielding and sun-proof structure of the device.

Contrary to the action when the rain and sun protection structure is unfolded, the motor pushes the unfolded edge (2) of the rain and sun protection structure to rotate clockwise (overlooking) to the fixed edge (3) of the rain and sun protection structure until the control unit collects the unfolded edge The specified retracting angle has been reached, and the control motor stops running.

The interior of the shell is divided into upper and lower cabinets, with dry and wet partitions, the upper cabinet is a dry cabinet, and the lower cabinet is a wet cabinet. The dry box is used to place the drive mechanism, and the wet box is used to place the rainproof and sunshade structure. Both can deposit rain-proof sunshade structure like this, have certain protective effect to this mechanism, can prevent rainwater from dripping on the drive mechanism again by the awning (6) that is drenched with rain, cause invisible corrosion and short circuit of motor. Because the box body is installed on the roof of the bus, it needs to be inclined at a certain angle, and several drainage grooves are opened on the bottom plate of the wet box body to quickly discharge the rainwater dripped from the rain-proof and sun-proof structure. In addition, several ventilation holes can also be opened on the wall of the leeward side of the wet box to make the rain-shielding and sun-proof structure dry as soon as possible, so as to prolong the service life of the rain-shielding and sun-proof structure.

The rain-proof and sun-proof structure is composed of a canopy, umbrella ribs and guide rings. The function of the ribs is to support the awning. There are two round holes on each rib, and the ribs pass through the two holes to guide rings with different radii. When the rain-proof and sun-proof structure is deployed, the guide ring plays a guiding role to ensure that the rain-shield and sun-proof structure can be correctly deployed, and when retracted, the rain-shield and sun-proof structure can be accurately returned to the retracted position. The two guide rings also have the function of supporting the ribs, so that the rain-proof and sun-proof structure has the required windproof strength. And by adjusting the relative heights of the two guide rings, the rain-shielding and sun-protecting structure can have different inclination angles.

The driving mechanism is composed of a driving motor. The drive motor adopted in this device is a 24V DC geared motor, which can directly use the 24V DC power supply on the vehicle, and does not need to use a deceleration mechanism. When the rain-shielding and sun-proof structure is deployed, the motor drives the unfolding edge of the rain-shielding and sun-proof structure to rotate counterclockwise (overlooking), and the rain-shielding and sun-proof structure is deployed along the circumferential direction under the guidance of the guide ring. When the rain-shielding and sun-protecting structure reaches the prescribed deployment position, the control device controls the motor to stop rotating according to the signal returned by the angle sensor.

A drainage groove is opened on the bottom plate of the housing, so that the rainwater brought into the box body of the automatic rain-shielding and sun-proofing device by the rain-shielding and sun-proof structure is quickly discharged. In addition, the box body makes the entire car door automatic rain-shielding and sun-protecting device a complete whole, and can be installed on any type of passenger car and other vehicles after connecting the power supply and the control switch signal line.

The control mechanism of the automatic rain-shielding sunscreen device for the car door includes a control unit, an angle sensor and a photoelectric proximity switch. The control unit collects the signals of the angle sensor, the photoelectric proximity switch, the control switch of the automatic rainproof and sunscreen device of the car door and the door switch, and controls the unfolding or retraction of the rainproof and sunscreen structure. The photoelectric proximity switch is installed on the unfolding side of the retractable rain-shielding and sun-proof structure, so that the device can automatically stop when it encounters obstacles during the unfolding process, so as to avoid unexpected disturbances to passengers and vehicles due to the unfolding of the device. Influence;

The control switch of this device is integrated with the door control switch of the passenger car to provide instructions for driving the motor, and the driver can control the switch of the automatic rain and sun protection device for the car door according to the actual weather conditions, which can reduce the number of times the device is used In order to prolong the service life, at the same time, the driver's burden will not be increased due to the increase of the driver's operation steps.

The device can be opened by the driver according to the actual weather conditions when the car arrives at the station or automatically opened with the opening of the car door, so that passengers can quickly get on and off the car without using an umbrella without being affected by the weather. When the car door is closed, the device is automatically stowed, which does not affect the normal operation of the vehicle and does not change the driver's driving habits.

The driving mechanism is composed of a driving motor, a driving gear and a driven gear. The driving motor drives the driving gear, and the shaft of the driven gear is fixed on the expanded edge of the awning. When it is opened, the motor drives the unfolding side of the awning to rotate, and the awning is unfolded under the guidance of the guide ring. When the awning reaches the unfolded position, the limit switch acts to control the motor to stop rotating, and the locking mechanism fixes the awning at the unfolded position. .

The box body is designed as two layers, the upper layer is the awning box, and the lower layer is the drive mechanism box to achieve dry and wet separation. The upper side of the partition between the upper and lower layers has a drainage groove, so that the water brought into the awning box by the awning is quickly discharged.
