It should be noted that the vehicle in the present application may refer to a large car, a small car, a special-purpose car, etc. For example, according to the vehicle type, the vehicle in the present application may be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV) or other vehicle types. For a vehicle, a wheel hub, a power source, and a transmission system arranged between the wheel hub and the power source are generally provided. The transmission system can transmit the power provided by the power source to the wheel body, so that the wheel body rotates, thereby driving the vehicle to travel.
[0035] It should be noted that in the embodiments of the present application, the type of the power source of the vehicle is not limited.

[0036] At present, the sun visor needs to be matched with a base and a rotating part, and the base is fixed to the ceiling inside the vehicle with bolts to prevent direct sunlight from affecting driving. When the driver encounters glaring sunlight, he needs to manually flip and adjust the rotation angle of the sun visor; but since the traditional sun visor has a large flip angle range, it takes up a large space in the car. Compared with the existing sun visor structure, the sunshade device 100 provided in the embodiment of the present application can be unfolded and retracted by adjusting components, and has a simple and compact structure; the sunshade device 100 requires a small operating space during the unfolding process, and the volume of the sunshade device 100 in the retracted state is small, which reduces the occupied space inside the vehicle.
[0037] For example, the existing sun visor structure includes a sun visor and a mounting base, which is fixed to the ceiling inside the vehicle by bolts, and the sun visor is hinged to the mounting base; the sun visor is rotated to be perpendicular to the forward direction of the vehicle to achieve the purpose of shading and prevent sunlight from directly shining into the driver's eyes; however, due to the large area of the sun visor, the sun visor structure needs to occupy a large space in both the open and stored states.

The main rod 221 and the sub-rod 222 are used to form a first angle, which changes with the swing of the main rod 221, and the swing plane of the main rod 221 is parallel to the unfolding plane of the sunshade structure 1. The first end of the sunshade structure 1 is driven to rotate by utilizing the adjustment component 22, thereby driving the second end of the sunshade structure 1 to be unfolded and away from the first end of the sunshade structure 1, or driving the second end of the sunshade structure 1 to be retracted and close to the first end of the sunshade structure 1; wherein the first end of the sunshade structure 1 can be directly rotatably connected to the vehicle, and in addition, when the sunshade device 100 swings through the main rod 221 and increases the first angle, the distance between the end of the main rod 221 close to the first end of the sunshade structure 1 and the end of the auxiliary rod 222 close to the second end of the sunshade structure 1 increases, thereby driving the second end of the sunshade structure 1 away from the first end of the sunshade structure 1 to enable the sunshade structure 1 to be unfolded; the sunshade device 100 swings through the main rod 221 and increases the first angle. When the first angle is reduced, the distance between the end of the main rod 221 close to the first end of the sunshade structure 1 and the end of the auxiliary rod 222 close to the second end of the sunshade structure 1 is reduced, thereby driving the second end of the sunshade structure 1 close to the first end of the sunshade structure 1, so that the sunshade structure 1 is rolled up until the main rod 221 and the auxiliary rod 222 are folded; and because the swing plane of the main rod 221 is parallel to the unfolding plane of the sunshade structure 1, the space required for the sunshade structure 1 to be unfolded is relatively small; the sunshade device 100 can be unfolded and rolled up by using the adjustment component 2, and the structure of the sunshade device 100 is simple and compact, and the operating space required during the unfolding process is small. The volume of the sunshade device 100 in the rolled-up state is relatively small, reducing the occupied interior space of the vehicle. It should be noted that the main rod 221 and the auxiliary rod 222, as well as the auxiliary rod 222 and the second end of the shading structure can be connected by setting a through hole at the end of the rod and cooperating with a pin shaft, so that the main rod 221 and the auxiliary rod 222 can rotate relative to each other, and the auxiliary rod 222 and the second end of the sunshade structure 1 can rotate relative to each other; the first end of the sunshade structure 1 can adopt an axis structure and a hole structure to cooperate with each other, or adopt a hinge, a rotating joint and other structures to achieve a rotatable connection with the vehicle.
[0039] In a possible implementation of the present application, the sunshade structure 1 includes a sunshade curtain 11, a first rotating shaft 12 and a connecting strip 13.

By rotating the first rotating shaft 12, the second end of the sunshade curtain 11 is lowered, and the connecting strip 13 provides gravity and support, so that the sunshade curtain 11 can be smoothly unfolded; the sunshade curtain 11 is easy to store in the rolled-up state, the sunshade curtain 11 is rolled up on the outer surface of the first rotating shaft 12, the connecting strip 13 is located below the first rotating shaft 12, the main rod 221 and the auxiliary rod 222 are folded and located between the first rotating shaft 12 and the connecting strip 13; the sunshade structure 1 and the adjustment component 2 cooperate with each other so that the sunshade device 100 can realize the functions of unfolding and rolling up, and at the same time, the sunshade device 100 occupies less vehicle space whether in the unfolding process or in the rolled-up state; compared with the existing sun visor structure, it does not need to be flipped to achieve opening and storage, and its structure is more compact and the operation is more convenient. The connecting strip 13 can provide support for the unfolding of the sunshade curtain 11 , and facilitate the connection between the second end of the sunshade curtain 11 and the auxiliary rod 22 .
[0040] In a possible implementation of the present application, the sunshade device 100 also includes a shell 3, which is used to connect to the vehicle and has an opening; the sunshade structure 1 and the adjustment assembly 2 are both installed in the shell 3; the first shaft 12 is rotatably connected to the shell 3, and the opening is used for the second end of the sunshade curtain 11 to extend and pass. Among them, the two ends of the first shaft 12 cooperate with the hole structure on the shell 3 to achieve a rotatable connection, so that the rotating assembly can drive the first shaft 12 to rotate, and the second end of the sunshade curtain 11 extends from the opening of the cavity to the outside of the cavity, and the connecting strip 13 is located outside the shell 3. The sunshade curtain is controlled to unfold or retract by changing the rotation direction of the first shaft 12. It should be noted that one end of the adjustment assembly 2 provided with the auxiliary rod 222 also extends to the outside of the cavity through the opening. Finally, by installing the shell 3 to one end of the ceiling in the vehicle along the forward direction of the vehicle, it has the advantage of convenient installation, and the shell 3 is used to provide protection for the sunshade structure 1 and the adjustment assembly 2.
[0041] In a possible implementation of the present application, the sunshade device 100 includes at least two groups of adjustment components 2, and the two groups of adjustment components 2 are arranged along the length direction of the first rotating shaft 12. The sunshade structure 1 realizes the opening and closing functions by using the two groups of adjustment components 2 to cooperate with each other, which can make the process of unfolding and retracting the sunshade structure 1 smoother, thereby improving the stability of the sunshade structure when unfolded.
[0042] In a possible implementation of the present application, the housing 3 includes a shell 31 and a bracket 32, the shell 31 is provided with a cavity, the bracket 32 is provided in the shell, and the two ends of the first rotating shaft 12 are rotatably connected to the two ends of the bracket 32.

[0044] In a possible implementation of the present application, the adjustment assembly 2 also includes a winding structure 7, and the winding structure 7 includes a coil spring, the outer ring end of the coil spring is connected to the bracket 32, and the inner ring end of the coil spring is connected to the end of the first rotating shaft 12. By using the coil spring, the sunshade structure 1 can be automatically wound up, and the coil spring can continuously provide a large restoring force in a small space. When the driving member 21 drives the transmission structure 22 to unfold the sunshade structure 1, the coil spring is in a tightened state, and the driving member 21 can make the sunshade structure 1 continue to unfold through the self-locking effect; if the sunshade structure 1 needs to be wound up, the self-locking effect of the driving member 21 is turned off, and the coil spring quickly returns to its original state, releasing the stored elastic potential energy, providing the first rotating shaft 12 with a rotational power, and then the blackout curtain is wound up. By using the coil spring to drive the blackout curtain to automatically wind up, the energy loss required when the blackout curtain is wound up can be reduced. Specifically, the sunshade curtain is unfolded by rotating the first rotating shaft 12 counterclockwise, and when the coil spring returns to its original state, it drives the first rotating shaft 12 to rotate clockwise to reel in the sunshade curtain. It should be noted that the coil spring can also adopt existing technical structures such as springs or torsion springs to enable the sunshade curtain 11 to achieve the function of automatic reeling; wherein the driving member 21 includes a driving motor, and specifically, the driving motor can be a stepping motor. By adding feedback devices such as encoders to the control of the stepping motor, closed-loop control can be achieved, the position of the load can be monitored, and appropriate feedback force can be applied when necessary to achieve the self-locking function. The self-locking function of the stepping motor can refer to the existing technology and will not be repeated here.
[0045] In a possible implementation of the present application, a second rotating shaft 2211 is provided at one end of the main rod 221, and the second rotating shaft 2211 is transmission-connected with the driving member 21, and the output shaft of the driving member 21 is transmission-connected with the second rotating shaft 2211. The output shaft of the driving member 21 is meshed with the second rotating shaft 2211 to make the main rod 221 swing, and one end of the main rod 221 away from the second rotating shaft 2211 is hinged with the auxiliary rod 222, and the main rod 221 swings and drives the auxiliary rod 222 to swing, thereby increasing or decreasing the first angle β formed by the main rod 221 and the auxiliary rod 222, and when the first angle β increases, the sunshade structure 1 is unfolded, and when the first angle β decreases, the sunshade structure 1 is rolled up, and by using the driving member 21 to drive the main rod 221 to swing, the sunshade device 100 can realize the function of automatic opening and closing through a simple structure, and at the same time, due to the simple structure, the sunshade device 100 has a small overall volume, which avoids occupying the space in the vehicle.

[0046] In a possible implementation of the present application, the sunshade device 100 also includes a first acquisition unit 4, a second acquisition unit 5, a calculation unit and a storage unit.

Among them, the first acquisition unit 4 can be installed on the vehicle, and the first acquisition unit 4 faces the forward direction of the vehicle; the first acquisition unit 4 can use a visual camera or a laser radar method; the following first acquisition unit 4 uses a visual camera as an example:
[0047] The first acquisition unit 4 acquires an image of the vehicle's forward reverse direction, obtains a second angle α between the sun and the vehicle's forward reverse direction through image recognition, and then acquires the eye coordinate position (X1, Z1) of the person inside the vehicle through the second acquisition unit 5. At the same time, the coordinate position (X2, Z2) of the first end of the sunshade structure 1 can be preset in advance through the calculation unit; wherein, the coordinate position of the first end of the sunshade structure 1 can specifically be the coordinate position of the first rotating shaft 12; the calculation unit then obtains the preset descent height value H of the second end of the sunshade structure 1 through the mapping relationship between the second angle α, the coordinate position (X1, Z2) of the first end of the sunshade structure 1, and the eye coordinate position (X2, Z2), and the calculation unit is used to drive the driving member 21 according to the preset descent height value H, so that the driving member 21 drives the first rotating shaft 12 to rotate until the descent height of the second end of the sunshade curtain reaches the preset descent height value H. wherein, the specific calculation process of the calculation unit is as follows:
[0048] H=(Z2-Z1)-arctanα*(X2-X1);

[0050] In a possible implementation of the present application, the sunshade device 100 further includes a light sensor 6, which is electrically connected to the first acquisition unit 4, the second acquisition unit 5 and the calculation unit, respectively. The light sensor 6 is used to face the forward direction of the vehicle, and the light sensor 6 is used to obtain the luminous intensity value of the sight light source, and open or close the first acquisition unit 4 and the second acquisition unit 5 according to the luminous intensity value of the sight light source obtained. The light sensor 6 can be arranged inside or outside the front windshield of the vehicle, and the light sensor 6 is used to face the forward direction of the vehicle and obtain the real-time luminous intensity value of the target light source. The light sensor 6 can preset a maximum luminous intensity threshold, and by comparing the real-time luminous intensity value of the target light source with the maximum luminous intensity threshold, if the real-time luminous intensity value of the target light source is greater than or equal to the maximum luminous intensity threshold, the light sensor 6 controls the driving member 21 to operate, and drives the second end of the sunshade structure member 1 to descend to a preset height. If the real-time luminous intensity value of the target light source is less than the maximum luminous intensity threshold, the light sensor 6 uses the calculation unit to make the driver 21 drive the sunshade structure 1 to retract or keep the sunshade structure 1 in the retracted state; or the light sensor 6 uses the calculation unit to make the driver 21 release the self-locking effect, so that the coil spring drives the sunshade structure 1 to retract.

The angle sensor obtains the rotation angle of the driving member 21. If the rotation angle of the driving member 21 is 0, the angle sensor determines that the sunshade structure 1 is in a retracted state. When the real-time luminous intensity value of the target light source is less than the maximum luminous intensity threshold, the angle sensor enables the optical sensor to control the sunshade structure 1 to maintain the retracted state. If the rotation angle of the driving member 21 is greater than 0, the angle sensor determines that the sunshade structure 1 is in an unfolded state. When the real-time luminous intensity value of the target light source is less than the maximum luminous intensity threshold, the angle sensor enables the optical sensor to control the sunshade structure 1 to retract. When the real-time luminous intensity value of the target light source is greater than or equal to the maximum luminous intensity threshold, if the rotation angle of the driver 21 is greater than 0, the angle sensor makes the light sensor control the sunshade structure 1 to maintain the unfolded state. The angle sensor can use a Hall sensor to identify the winding phase position information of the driver 21 and convert it into an electrical signal. The driver 21 obtains the position information of the rotor by reading the output level signal of the Hall sensor, and then obtains the rotation angle of the driver 21; or the angle sensor can use an angle encoder to obtain the rotation angle of the driver 21 through the angle encoder.
