[0052] Specifically, the arrangement of the first body 141, the driving gear 142 and the connecting portion 143 improves the structure of the connecting shaft 14, making the structure of the connecting shaft 14 compact and saving space in the vehicle.

[0053] In one embodiment, please refer to Figure 3 , the angle acquisition member 12 includes a potentiometer body 121 and a rotating gear 122 that are connected to each other. The potentiometer body 121 is connected to the flipping assembly 11, the potentiometer body 121 is spaced apart from the first body 141, and the rotating gear 122 meshes with the driving gear 142.

Optionally, the rotating gear 122 meshes with the driving gear 142 on the connecting shaft 14, and the potentiometer body 121 can be fixed on the cover 21 of the flipping mechanism 10. When the driving gear 142 drives the connecting shaft 14 to rotate, it will simultaneously drive the rotating gear 122 of the potentiometer to rotate. The rotation of the rotating gear 122 will change the position of the sliding end in the resistor body of the potentiometer, thereby changing the resistance value in the circuit and obtaining the corresponding angular position.

[0055] Optionally, the angle acquisition component 12 is electrically connected to the control system of the flipping mechanism 10, which can realize the start and stop of the flipping mechanism 10 at a predetermined angle and can also realize angle storage. In the next screen flipping, the flipping mechanism 10 can flip to the stored angle to realize the angle memory function.

[0056] Optionally, the angle acquisition component 12 can also be a return sensor with a rotating gear 122. Similarly, the return sensor can obtain, calculate, and transmit the return angle of the rotating gear 122 in real time through gear meshing.

[0057] Optionally, the rotating gear 122 is a cylindrical gear. Optionally, the above setting uses the method of gear meshing to obtain angle information. The direct meshing of the rotating gear 122 and the driving gear 142 converts the angular position information of the rotating gear 122 into changes in forms such as resistance, capacitance, or inductance in the sensor, and then records the angular position information of the system.

[0058] Specifically, the above setting improves the structure of the angle acquisition component 12, enhances the convenience of the flipping mechanism 10 for obtaining angle information, and saves vehicle space.

The first gear sensor 123 is used to collect the rotation angle of the driving gear 142.

[0060] Optionally, the angle acquisition component 12 can monitor the angle by sensing the magnetic field change generated by the rotation of the driving gear 142. For example, the angle acquisition component 12 can adopt a first gear sensor 123. The first gear sensor 123 can be installed on one side close to the driving gear 142 and one side of a certain gear in the flipping assembly 11, and fixed on the cover 21 of the flipping mechanism 10. Moreover, the first gear sensor 123 is electrically connected to the printed circuit board. The first gear sensor 123 integrates a Hall element inside. By using the interaction between the Hall element and the magnetic field, when the connecting shaft 14 rotates, any gear in the transmission part will rotate, resulting in a change in the magnetic field. The Hall element in the first gear sensor 123 converts the changing magnetic field into a voltage signal, which is processed by the circuit and then converted into angle information.

[0061] Specifically, the above settings improve the structure of the angle acquisition component 12, enhance the convenience of the flipping mechanism 10 to obtain angle information, and save vehicle space.

[0062] In one embodiment, the angle acquisition component 12 further includes a second gear sensor and a driven gear. The second gear sensor is disposed opposite to the driven gear. The second gear sensor is used to collect the rotation angle of the driven gear, and the driven gear is driven by the driving gear 142.

[0063] In one embodiment, please refer to Figure 5 , the angle acquisition component 12 further includes an angle sensor 124. The angle sensor 124 is connected to the flipping assembly 11. The angle sensor 124 is disposed opposite to the driving gear 142. The angle sensor 124 is used to collect the rotation angle of the driving gear 142.

[0064] Optionally, the angle acquisition component 12 can use the angle sensor 124 to monitor the angle. The angle sensor 124 is soldered on the printed circuit board, and the printed circuit board is fixed on the cover 21 of the flipping mechanism 10. When the angle sensor 124 is assembled, the angle sensor 124 is aligned with one side of the driving gear 142 of the connecting shaft 14 or a certain gear in the flipping assembly 11. The angle sensor 124 integrates highly sensitive playback elements inside. By using the magnetoresistive effect, when the gear rotates, the resistance of the playback element changes due to the magnetic field change generated by the rotation of the gear, and further changes into a voltage change in the circuit to record the angle change, realizing angle monitoring. Similarly, a Hall element can also be used inside the angle sensor 124. By using the Hall effect, the magnetic field change generated by the rotation of the gear is converted into a potential difference to form a voltage change, thereby realizing angle monitoring. Optionally, the angle sensor 124 can also be integrated in the printed circuit board of the motor 20, converting the magnetic field change generated by the rotation of the stator or rotor in the motor 20 into an electrical signal, thereby recording the rotation angle of the motor 20, and then converting it into the flipping angle of the in-vehicle screen 13 according to the gear ratio to realize the angle monitoring function.

[0065] Specifically, the above arrangement improves the structure of the angle acquisition member 12, improves the convenience of the flip mechanism 10 in acquiring angle information, and saves vehicle space.

[0067] Optionally, the angle acquisition member 12 may use an angular displacement sensor 125 for angle monitoring. The angular displacement sensor 125 may be fixed on the cover 21 of the flip mechanism 10. The shaft of the angular displacement sensor 125 needs to be directly connected to a gear or a connecting shaft 14 in the flip assembly 11 through a shaft connector. When the gear rotates, the shaft of the angular displacement sensor 125 is driven to rotate. There are many ways to obtain the change in angle. One is to connect the shaft of the angular displacement sensor 125 to a sliding resistor to convert the angle change into a resistance change; the other is to connect the shaft of the angular displacement sensor 125 to an electrode in a capacitor. When the distance between the two electrodes changes, the capacitance value is inversely proportional to the electrode distance, thereby converting the angular displacement information into an electrical signal for monitoring.

[0068] Optional, please refer to Figure 7 , the angle acquisition member 12 can use a photoelectric sensor for angle monitoring.

The photoelectric sensor needs to be installed on the cover 21 of the fixed flip mechanism 10 parallel to the light source. The photoelectric sensor can be a photoelectric encoder or a light receiver. When the grating plate 31 rotates, the light source falls on the photoelectric encoder through the slit, and the photoelectric encoder generates a pulse converted into a digital signal, thereby recording the corresponding angle position. In this embodiment, the photoelectric encoder can be used in the motor 20, relying on the optical encoder of the motor 20 to complete the angle monitoring, and then convert it according to the gear ratio and the speed.

[0069] Optional, please refer to Figure 8, the angle acquisition component 12 can use a wire-pulling sensor for angle monitoring. The rotary displacement sensor needs to be fixed on the cover 21 of the flipping mechanism 10. The hub 35 is connected to the connecting shaft 14 through a steel wire 34. The hub 35 is coaxially connected to a magnet 36. When the wire-pulling generates displacement, it drives the hub 35 to rotate, causing the magnet 36 connected to the hub 35 by the shaft to rotate, thereby changing the magnetic field of the magnet 36. The magnetic sensor 37 opposite to the magnet 36 is connected to the microprocessor, converting the change in the magnetic field into magnetic-sensitive angle information, thus realizing angle monitoring.

[0070] Optionally, please refer to Figure 9 , the angle acquisition component 12 can be an inductive sensor. The inductive sensor includes a rotor plate 38 and a stator plate 39. The rotor plate 38 is fixed on the rotating shaft of the motor 20. The rotor plate 38 contains a resonator. The stator plate 39 is fixed on the motor 20 and remains relatively stationary with respect to the motor 20 housing. The stator plate 39 contains a transmitting coil and a receiving coil. When an alternating current of a certain frequency is passed through the transmitting coil in the stator plate 39, it will generate a magnetic field and couple it to the rotor. During the rotation of the rotor, the electromagnetic signal containing angle information is feedback-coupled to the receiving coil. The decoding circuit in the stator plate 39 converts the angle information into a digital signal through procedures such as amplification, acquisition, calculation, and correction, thus realizing angle monitoring.
