The roller is rotatably mounted on the mounting structure, and the elastic element is connected to the roller.

Alternatively, The sunshade device also includes a mounting structure, an elastic element, a fixed shaft, and a movable shaft. The fixed shaft is fixedly mounted to the mounting structure, and the movable shaft is rotatably mounted to the mounting structure. One end of the roller is rotatably connected to the fixed shaft, and the other end of the roller is fixedly connected to the movable shaft.

[0014] Through the above technical solution, since the second end of the sunshade is connected to the conductive component, and the conductive component is located in the magnetic field, the physical principle of the "left-hand rule" is used to enable the conductive component to directly generate linear motion under the drive of the magnetic field force when energized, thereby driving the second end of the sunshade connected to it to move closer to or away from the roller, realizing the unfolding or rolling up of the sunshade.

[0015] Compared with related technologies that require a motor-driven roller and a mechanical traction system consisting of pulleys and steel wire ropes to move the sunshade, the sunshade device disclosed in this invention has made a fundamental change in its driving principle. Since the movement of the conductive parts is directly generated by electromagnetic action, there is no need to convert the rotational motion into linear traction. This eliminates the need for a complex mechanical transmission mechanism consisting of multiple components such as motors, pulleys, and steel wire ropes. On the one hand, this helps to reduce the structural complexity of the sunshade device; on the other hand, it can fundamentally avoid mechanical transmission and friction noise sources, thereby helping to eliminate abnormal noises during the operation of the sunshade.

Detailed Implementation

[0027] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0028] In this disclosure, unless otherwise stated, directional terms such as "up," "down," "top," "bottom," "front," "rear," "left," and "right" are generally defined according to the position of the vehicle in normal driving conditions (see reference for details). Figure 1 (As shown), it is only for the convenience of describing this disclosure and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or a specific orientation construction and operation, and therefore should not be construed as a limitation of this disclosure. "Inner" and "outer" refer to the inner and outer contours of the corresponding components. In addition, the terms "first," "second," etc., are used to distinguish one element from another and do not have any order or importance.

[0029] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "connect," "link," and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0030] The sunshade devices in related technologies have complex structures and are prone to noise. The main reason for this is that the sunshade devices in related technologies typically include a first crossbeam and a second crossbeam spaced apart. The first crossbeam is equipped with a roller and a motor, and the second crossbeam is equipped with a pulley. Two guide rails are provided between the first and second crossbeams, extending along the interval between the first and second crossbeams. One end of the sunshade curtain is connected to the roller, and the other end is connected to the side strip. Both ends of the side strip are slidably connected to the two guide rails. The sunshade device also includes a first steel wire rope and a second steel wire rope. The output shaft of the motor is connected to the steel wire rope, and the other end of the steel wire rope passes around the pulley and is connected to the side strip.

[0031] Taking the unfolding of a sunshade as an example, it requires the output shaft to be rotated by a motor to wind up the steel wire rope, so that the other end of the steel wire rope pulls the edge strip to move away from the roller, thereby driving the unfolding of the sunshade. The structure is complex. In other words, the movement of the sunshade in the relevant technology depends on a mechanical traction system composed of a motor, pulleys and steel wire rope. Its structural complexity and abnormal noise mainly stem from the presence of multiple moving parts (such as the motor output shaft and pulleys) and mechanical friction between the parts (such as the friction of the steel wire rope).

[0032] In view of this, such as Figures 1 to 9 As shown, this disclosure provides a sunshade device, including a sunshade curtain 10, a roller 20, a magnetic field generating structure 30, and a conductive element 40. The first end of the sunshade curtain 10 is connected to the roller 20, which is configured to rotate. The roller 20 can rotate actively or passively (such as being driven to rotate when the sunshade curtain 10 moves). The magnetic field generating structure 30 is used to generate a magnetic field. The second end of the sunshade curtain 10 is connected to the conductive element 40, which is located within the magnetic field (the magnetic field covers the range of motion of the conductive element 40), so that the conductive element 40 can move under the action of the magnetic field when an electric current is applied, thereby driving the sunshade curtain 10 to move.

[0033] Through the above technical solution, since the second end of the sunshade curtain 10 is connected to the conductive element 40, and the conductive element 40 is located in the magnetic field, the physical principle of the "left-hand rule" (that is, a current-carrying conductor will be subjected to the Ampere force in a magnetic field) is used to enable the conductive element 40 to directly generate linear motion under the drive of the magnetic field force when energized, thereby driving the second end of the sunshade curtain 10 connected to it to move closer to or away from the roller 20, so as to realize the unfolding or rolling up of the sunshade curtain 10.

[0034] Compared with the related technologies that require a motor-driven roller and a mechanical traction system consisting of pulleys and steel wire ropes to move the sunshade curtain, the sunshade device disclosed in this invention has made a fundamental change in the driving principle. Since the movement of the conductive component 40 is directly generated by electromagnetic action, there is no need to convert the rotational motion into linear traction. This eliminates the need for a complex mechanical transmission mechanism consisting of multiple components such as motors, pulleys, and steel wire ropes. On the one hand, this helps to reduce the structural complexity of the sunshade device. On the other hand, it can fundamentally avoid mechanical transmission and friction noise sources, thereby helping to eliminate abnormal noises during the operation of the sunshade curtain 10.

[0035] Furthermore, the reduction of multiple components such as motors, pulleys, and steel wire ropes can also reduce the use of plastic parts, which helps to improve the odor of the sunshade device (i.e., reduce the odor caused by plastic parts being exposed to sunlight).

[0036] Furthermore, according to the left-hand rule, the magnitude of the force exerted on the conductive element 40 in the magnetic field is proportional to the magnitude of the current passing through it. Therefore, by adjusting the magnitude of the current applied to the conductive element 40, the driving force on the conductive element 40 can be changed linearly and continuously, thereby enabling smooth and stepless adjustment of the unfolding or retracting speed of the sunshade curtain 10.

[0037] According to the left-hand rule, the direction of the force on a current-carrying conductor in a magnetic field depends on both the direction of the current and the direction of the magnetic field. Therefore, the direction of movement of the sunshade curtain 10 driven by the conductive element 40 can be changed by keeping the direction of the current applied to the conductive element 40 unchanged and changing the direction of the magnetic field generated by the magnetic field generating structure 30. Alternatively, the direction of movement of the sunshade curtain 10 driven by the conductive element 40 can be changed by keeping the direction of the magnetic field generated by the magnetic field generating structure 30 unchanged and changing the direction of the current applied to the conductive element 40. Thus, the sunshade curtain 10 can be unfolded or rolled up. This disclosure does not limit this.

[0038] For example, in the case where the magnetic field generating structure 30 mentioned below includes a first magnet 31 and a second magnet 32, and the first magnet 31 and the second magnet 32 ​​are permanent magnets, the direction of movement of the sunshade curtain 10 can be changed by changing the direction of the current. In the case where the magnetic field generating structure 30 mentioned below includes a first magnet 31 and a second magnet 32, and the first magnet 31 and the second magnet 32 ​​are electromagnets, the direction of movement of the sunshade curtain 10 can be changed by changing the direction of the magnetic field.

[0039] This disclosure does not limit the type of the magnetic field generating structure 30. As one embodiment, such as Figures 2 to 5As shown, the magnetic field generating structure 30 includes a first magnet 31 and a second magnet 32. The first magnet 31 and the second magnet 32 ​​are located on opposite sides of the conductive member 40 and extend along the moving direction of the conductive member 40. The magnetic pole of the first magnet 31 facing the second magnet 32 ​​is opposite to the magnetic pole of the second magnet 32 ​​facing the first magnet 31.

[0040] According to the left-hand rule, the direction of the electromagnetic force on the conductive element 40 is perpendicular to the direction of the magnetic field. Therefore, the first magnet 31 and the second magnet 32 ​​are located on opposite sides of the conductive element 40 and extend along the direction of movement of the conductive element 40. The magnetic poles of the first magnet 31 facing the second magnet 32 ​​are opposite to the magnetic poles of the second magnet 32 ​​facing the first magnet 31. This can form a magnetic field with consistent direction and stable strength on both sides of the moving path of the conductive element 40, so that the conductive element 40 is always in the magnetic field throughout the entire movement stroke. It can also keep the direction of the magnetic field perpendicular to the direction of movement of the conductive element 40, which is conducive to keeping the direction of the electromagnetic force on the conductive element 40 consistent with its direction of movement. This is beneficial to efficiently using electromagnetic force to control the movement of the conductive element 40.

[0041] Here, the first magnet 31 and the second magnet 32 ​​can be permanent magnets or electromagnets, and this disclosure does not limit them.

[0042] As another implementation, the magnetic field generating structure 30 may include a U-shaped magnet with two pole pieces arranged opposite each other and extending along the moving direction of the conductive member 40, which can also form the desired uniform magnetic field between the two pole pieces.

[0043] This disclosure does not limit the specific structure of the conductive element 40. For example, the conductive element 40 can be constructed as a plate-shaped element, a rod-shaped element, etc.

[0044] Optionally, such as Figure 1 , Figure 4 and Figure 5 As shown, the sunshade device also includes two guide rails 50, and guide grooves 51 are provided on the guide rails 50. The two ends of the conductive element 40 are respectively movably disposed in the guide grooves 51 of the two guide rails 50.

[0045] This configuration restricts the degree of freedom of the conductive element 40 in the direction perpendicular to the movement direction through the guide groove 51, preventing the conductive element 40 from shifting laterally, swinging, or twisting during movement. This helps ensure that the conductive element 40 drives the sunshade curtain 10 to move along the required trajectory, avoiding the risk of interference or collision between the conductive element 40 and surrounding components (such as the first magnet 31 and the second magnet 32) due to movement instability.

[0046] Optionally, such as Figure 5 As shown, the sunshade device includes an insulating sleeve 41 that wraps around at least a portion of the conductive element 40.

[0047] The insulating sleeve 41 wraps around at least part of the conductive element 40, which can achieve physical insulation between at least part of the conductive element 40 and the external environment. This helps to avoid accidental electrical contact between the conductive element 40 and other components, thereby eliminating the risk of short circuit or leakage and improving the electrical safety of the sunshade device.

[0048] This disclosure does not limit the material of the insulating sleeve 41. For example, the material of the insulator may include, but is not limited to, ceramic, plastic and rubber.

[0049] Optionally, such as Figure 1 As shown, a first magnet 31 and a second magnet 32 ​​are installed on each of the guide rails 50.

[0050] This configuration ensures that both ends of the conductive element 40 are driven by electromagnetic force when an electric current is applied, thus guaranteeing the smoothness of the conductive element 40's movement. Furthermore, the mounting of the first magnet 31 and the second magnet 32 ​​on the guide rail 50 enhances the spatial compactness of the magnetic field generating structure 30 and the guiding structure of the sunshade device. This reduces the space occupied by the sunshade device and minimizes shading of the area covered by the sunshade curtain 10, allowing more light to pass through the area when the sunshade curtain 10 is rolled up.

[0051] This disclosure does not limit how the first magnet 31 and the second magnet 32 ​​are installed on the guide rail 50. They can be directly installed on the guide rail 50, for example, by adhesive bonding, or indirectly installed on the guide rail 50, for example, by adhesive bonding to the first glass 71 and the second glass 72 mentioned below. As long as the first magnet 31 and the second magnet 32 ​​are spatially installed on the guide rail 50 (i.e., both the first magnet 31 and the second magnet 32 ​​are adjacent to the guide rail 50), this disclosure does not limit this.

[0052] In order to apply current to the conductive element 40 that has been moved to any position, in one embodiment, both guide rails 50 are configured to conduct electricity and make conductive contact with the conductive element 40, and the two guide rails 50 are used to connect to a power source.

[0053] This configuration allows for the reuse of existing guide rails 50, meaning that guide rails 50 can serve as both guides for conductive elements 40 and electrodes for conductive elements 40, applying current to conductive elements 40 that have been moved to any position (so that current can flow into one end of conductive element 40 through one guide rail 50 and out the other end of conductive element 40 through another guide rail 50). This saves on dedicated flexible power cables, simplifies electrical connection structures, and avoids the risk of circuit failures caused by cable tangling, bending, or wear.

[0054] It is understandable that one of the two rails 50 can allow the current from the power supply to flow into the conductive element 40, and the other rail 50 can allow the current in the conductive element 40 to flow back to the power supply, thus forming a current loop.

[0055] In another embodiment of this disclosure, the conductive element 40 may also be connected to a power source via a flexible cable.

[0056] This disclosure does not limit the connection method between the guide rail 50 and the power supply. As one implementation method, such as Figure 3 and Figure 4 As shown, the sunshade device also includes an electrical connection structure 60. An electrical connection structure 60 is installed on both guide rails 50. The electrical connection structure 60 includes a connecting part 61 and a conductive part 62. The conductive part 62 is in conductive contact with the guide rail 50, and the connecting part 61 is used to connect to a power source.

[0057] Electrical connection structures 60 are installed on both guide rails 50. The connecting part 61 of the electrical connection structure 60 is connected to the power supply, and the conductive part 62 of the electrical connection structure 60 is in conductive contact with the guide rail 50. This allows the current from the power supply to flow into the conductive element 40 through one of the two electrical connection structures 60, and after flowing through the conductive element 40, it flows back to the power supply through the other of the two electrical connection structures 60, thus forming a current loop. The dedicated electrical connection structure 60 connects the guide rail 50 to the power supply, providing an interface for the electrical connection between the guide rail 50 and the power supply, making the electrical connection between the power supply and the guide rail 50 more reliable and easier to maintain.

[0058] Optionally, the connecting part 61 may be provided with a socket for plugging into a power cord connector. An electrical connector is connected between the socket and the conductive part 62, so that the power supply can be electrically connected to the guide rail 50 through the electrical connection structure 60.

[0059] Optionally, such as Figures 1 to 3 As shown, the sunshade device also includes a first glass 71 and a second glass 72, which are arranged opposite to each other and spaced apart, so that there is a receiving space between the first glass 71 and the second glass 72. The conductive element 40 and two guide rails 50 are located between the first glass 71 and the second glass 72, and an insulating element 53 is provided on the side surface of the guide rails 50 away from the receiving space.

[0060] The conductive component 40 and the two guide rails 50 are located between the first glass 71 and the second glass 72, which can isolate the moving parts in the glass interlayer. This can prevent the moving parts from being contaminated by dust and mechanically damaged, and can also help to achieve sound insulation for the moving parts. Furthermore, it can achieve efficient use of the space of the interlayer glass and reduce the space occupied. For example, when the first glass 71 and the second glass 72 are roof windows of a vehicle, it can help to reduce the encroachment of the sunshade structure on the passenger compartment space in the height direction of the vehicle.

[0061] Furthermore, the two guide rails 50 can support the gap between the first glass 71 and the second glass 72, thereby saving the need for a dedicated support component between the first glass 71 and the second glass 72.

[0062] An insulating element 53 is provided on the side surface of the guide rail 50 away from the receiving space, so that the insulating element 53, the first glass 71 and the second glass 72 can work together to achieve electrical isolation between the conductive guide rail 50 and the external environment, eliminating the risk of electric shock.

[0063] Optionally, both guide rails 50 can be bonded to both the first glass 71 and the second glass 72, and the insulating member 53 can be bonded to the guide rails 50, or it can also be bonded to both the first glass 71 and the second glass 72.

[0064] In this disclosure, the electrical connection structure 60 can be connected to any suitable position on the guide rail 50. This disclosure does not limit this. As one embodiment, such as Figure 3 and Figure 4 As shown, the electrical connection structure 60 can be disposed at the first end of the guide rail 50.

[0065] This configuration allows the power supply connection point to be located at the end of the guide rail 50, which facilitates clear power cable routing. For example, the first end of the guide rail 50 can be positioned close to the power supply, saving power cable length and reducing the difficulty of power cable routing. Furthermore, having the power supply connection point at the end of the guide rail 50 also avoids obstructing the movement of the conductive component 40.

[0066] In this disclosure, the conductive part 62 can be connected to the guide rail 50 in any suitable manner, and this disclosure does not limit this. As one embodiment, the conductive part 62 can be snapped into the guide groove 51.

[0067] This design utilizes the existing structure and space of the guide groove 51. The structure of the guide groove 51 forms a circumferential constraint on the conductive part 62, realizing the conductive connection and fixation between the conductive part 62 and the guide rail 50. This saves on special connectors and helps reduce the complexity of the shading structure.

[0068] Optionally, such as Figure 4and Figure 6 As shown, the electrical connection structure 60 may further include a first stop 63, a conductive part 62 mounted on the first stop 63, a connecting part 61 connected to the first stop 63, and one end of the first stop 63 protruding from the conductive part 62 so as to be able to contact the conductive part 40 before the conductive part 62.

[0069] As one end of the first stop 63 protrudes from the conductive part 62, when the conductive part 40 moves along the guide rail 50 and comes into contact with the electrical connection structure 60, the end of the conductive part 40 will preferentially make mechanical contact with the protruding first stop 63. The first stop 63 can play a mechanical buffering and hard limiting role for the movement of the conductive part 40, so as to avoid the conductive part 40 from impacting the conductive part 62.

[0070] In an embodiment where the electrical connection structure 60 can be located at the first end of the guide rail 50, the first stop 63 is located at the first end of the guide rail 50 and can limit the conductive element 40 to prevent the conductive element 40 from coming off the first end of the guide rail 50.

[0071] This disclosure does not limit the material of the first stop member 63; it can be a non-insulating material or an insulating material, such as rubber.

[0072] This disclosure does not limit the specific structure of the conductive part 62. As one embodiment, such as Figure 6 As shown, the conductive part 62 includes a conductive block 621, a first conductive spring 622, and a second conductive spring 623. The first conductive spring 622 and the second conductive spring 623 are located on opposite sides of the conductive block 621. The first conductive spring 622 and the second conductive spring 623 abut against the two side walls of the guide groove 51, respectively. The conductive block 621 abuts against the bottom wall of the guide groove 51.

[0073] The first conductive spring 622 and the second conductive spring 623 abut against the two side walls of the guide groove 51, which can not only fix the conductive part 62 in the guide groove 51, but also make conductive contact between the conductive part 62 and the guide rail 50. In addition, the conductive block 621 abuts against the bottom wall of the guide groove 51, which can realize multi-point electrical connection between the conductive part 62 and the guide rail 50, which is beneficial to improving the reliability of the electrical connection between the conductive part 62 and the guide rail 50.

[0074] Optionally, such as Figure 4 As shown, a first magnet 31 and a second magnet 32 ​​are mounted on both guide rails 50. The electrical connection structure 60 also includes a first stop 63, at least a portion of which is sandwiched between the first magnet 31 and the second magnet 32.

[0075] This arrangement utilizes the space between the existing first magnet 31 and second magnet 32 ​​to arrange the first stop 63, which helps to improve space utilization and compactness, and allows the first stop 63 to act as a support, supporting the gap between the first magnet 31 and second magnet 32.

[0076] Optionally, such as Figures 1 to 3 As shown, the sunshade device also includes a first glass 71 and a second glass 72, which are arranged opposite to each other and spaced apart to provide a space between them. A conductive element 40, a first magnet 31, a second magnet 32, and two guide rails 50 are located between the first glass 71 and the second glass 72. By placing the conductive component 40, the first magnet 31, the second magnet 32, and the two guide rails 50 all within the accommodating space formed by the first glass 71 and the second glass 72, the driving and guiding mechanism of the sunshade 10 can be isolated from the external environment. This helps to prevent the driving and guiding mechanism of the sunshade 10 from being contaminated by dust and mechanically damaged. It also helps to insulate the driving and guiding mechanism of the sunshade 10 from sound. Furthermore, it utilizes the existing gap between the first glass 71 and the second glass 72, which are laminated glass, thus reducing the space occupied by the sunshade device. For example, when the first glass 71 and the second glass 72 are roof windows of a vehicle, it helps to reduce the encroachment of the sunshade structure on the passenger compartment space in the height direction of the vehicle.

[0077] Optionally, such as Figure 5 As shown, the insulating sleeve 41 wraps around the portion of the conductive element 40 located outside the guide groove 51.

[0078] Since the part of the conductive component 40 inside the guide groove 51 is surrounded and isolated to a certain extent by the groove wall of the guide rail 50, while the part outside the groove is more likely to approach other surrounding components (such as the first glass 71, the second glass 72, the first magnet 31, and the second magnet 32), the insulating sleeve 41 wraps around the part of the conductive component 40 located outside the guide groove 51, which can accurately protect the part of the conductive component 40 that may make accidental electrical contact without affecting the conductive contact between the conductive component 40 and the guide rail 50.

[0079] Optionally, such as Figures 2 to 4 As shown, a first stop 63 is provided at the first end of the guide rail 50, which is used to stop the conductive component 40, and / or a second stop 52 is provided at the second end of the guide rail 50, which is used to stop the conductive component 40.

[0080] The first stop 63 can limit the movement of the conductive element 40 toward the first end of the guide rail 50, preventing the conductive element 40 from coming off the first end of the guide rail 50. The second stop 52 can limit the movement of the conductive element 40 toward the second end of the guide rail 50, preventing the conductive element 40 from coming off the second end of the guide rail 50.

[0081] In the embodiment where a first stop 63 is provided at the first end of the guide rail 50 and a second stop 52 is provided at the second end of the guide rail 50, the first stop 63 and the second stop 52 can jointly limit the movement range of the guide rail 50, so that the guide rail 50 can move within a suitable range to realize the unfolding or rolling up of the sunshade curtain 10.

[0082] In the case where the sunshade device also includes a first glass 71 and a second glass 72, optionally, the first stop 63 can be sealed at one end of the gap between the first glass 71 and the second glass 72, and the second stop 52 can be sealed at the other end of the first glass 71 and the second glass 72, together with the two guide rails 50, to form four sealing edges, enclosing the gap between the first glass 71 and the second glass 72 to form an accommodating space.

[0083] Taking the sunshade device applied to the roof sunroof of a vehicle as an example, the guide rail 50 can extend along the front and rear direction of the vehicle, and the two guide rails 50 can be set at intervals along the left and right direction of the vehicle. The first end of the guide rail 50 can be the rear end of the guide rail 50, and the second end of the guide rail 50 can be the front end of the guide rail 50.

[0084] Optionally, the second stop 52 can be bonded to the first glass 71 and the second glass 72.

[0085] Optionally, such as Figure 1 , Figure 7 and Figure 8 As shown, the sunshade device may also include a mounting structure 81, to which the roller 20 is rotatably mounted.

[0086] The mounting structure 81 can provide a fixed support point for the installation of the roller 20 in the specific application scenario of the sunshade device. The roller 20 can be rotatably installed in the application scenario through the mounting structure 81, which enables the roller 20 to reliably support the sunshade curtain 10 and have rotational freedom. It can rotate freely to realize the rolling and unfolding of the sunshade curtain 10, thereby achieving the effect of providing a stable and reliable mechanical foundation for the rolling movement of the sunshade curtain 10.

[0087] This disclosure does not limit the specific application scenarios of the sunshade device. For example, when the sunshade device is applied to the roof window of a vehicle, the mounting structure 81 can be the water tank of the vehicle, realizing the utilization of the existing structure of the vehicle body.

[0088] In the case of sunshades being used on vehicle sunroofs, alternatively, such as Figure 3 As shown, a cover is also connected between the mounting structure 81 and the first glass 71 (i.e., the upper glass), which completely isolates the roller 20 and the sunshade 10 from the outside of the vehicle.

[0089] Optionally, such as Figure 7 and Figure 8 As shown, the sunshade device may also include an elastic element 82, which is connected to the roller 20. The elastic element 82 is used to provide an elastic force to the roller 20 that enables the roller 20 to rotate in order to roll up the sunshade curtain 10.

[0090] During the unfolding process of the sunshade 10 by the conductive component 40, the rotation of the roller 20 forces the elastic component 82 to deform and store elastic potential energy. This causes the roller 20 and the conductive component 40 at both ends of the sunshade 10 to be pulled in different directions, ensuring that the unfolded portion of the sunshade 10 remains flat and avoids wrinkles. Furthermore, when it is necessary to roll up the sunshade 10, the elastic component 82 can release the stored potential energy, driving the roller 20 to rotate. This means that the rolling up process of the sunshade 10 does not rely entirely on the reverse electromagnetic drive of the conductive component 40, thus enabling the rolling up action of the sunshade 10 to be completed using elastic force to assist or independently, helping to reduce the energy consumption of driving the sunshade 10 to roll up.

[0091] For example, when the sunshade 10 needs to be unfolded, the controller (such as the vehicle's controller) can control the power supply to apply current to the conductive element 40, so that the conductive element 40 overcomes the elastic potential energy of the elastic element 82 and pulls the sunshade 10 to unfold. When the sunshade 10 needs to be rolled up, the controller can control the current applied to the conductive element 40 to reverse, so that the conductive element 40 and the elastic element 82 together drive the sunshade 10 to roll up. When the sunshade 10 moves to the designated position, the controller controls the current applied to the conductive element 40 to change direction again, and balances the pulling force of the conductive element 40 on the sunshade 10 and the pulling force of the elastic element 82 on the sunshade 10, thereby fixing the sunshade 10 at the required unfolding degree.

[0092] The methods for reversing the power output current and controlling the power output magnitude in vehicles are mature technologies in this field. This disclosure provides a two-stage connection interface with the power supply (i.e., the connection part 61 of the electrical connection structure 60 on the two guide rails 50). As for how the power supply side is designed, it depends on the specific application scenario. For example, when the sunshade device is applied to a vehicle, the vehicle's power management system can conveniently provide power and control it. Vehicles are usually equipped with a DC power supply (such as a battery) and a corresponding body control system (BCM) or a dedicated motor control unit. The connection part 61 of the two electrical connection structures 60 provided in this disclosure provides a standardized physical interface for the access of the vehicle's power system. The vehicle's power output cable can be connected to these two connection parts 61, thereby supplying power to the conductive component 40 through the two guide rails 50. The specific implementation of current commutation and magnitude control is also a mature technology in the field of vehicle electronic control. A typical implementation method is as follows: the vehicle control unit is connected to two connection parts 61 through an H-bridge drive circuit composed of power semiconductor devices (such as MOSFETs or IGBTs). By controlling the on and off sequence of different switching devices in the H-bridge circuit, the direction of current through the conductive element 40 can be changed conveniently and quickly, thereby realizing the switching of the sunshade 10's unfolding and retracting movements. At the same time, the control unit controls the H-bridge circuit through pulse width modulation (PWM) technology. By adjusting the duty cycle of the PWM signal, the average voltage or current output to the conductive element 40 can be continuously and accurately adjusted, thereby realizing stepless adjustment of the force on the conductive element 40 and its movement speed.

[0093] In summary, this disclosure provides a clear interface with the external power supply and control system through the electrical connection structure 60. As for the current commutation and magnitude adjustment functions on the power supply side, they can be directly implemented based on the existing mature electronic control technology on the vehicle. This does not require creative effort from those skilled in the art, nor does it constitute a technical obstacle to implementing this disclosure. Therefore, specific application scenarios will not be listed one by one.

[0094] Optionally, such as Figure 7 and Figure 8 As shown, the sunshade device may also include a fixed shaft 83 and a movable shaft 84. The fixed shaft 83 is fixedly installed on the mounting structure 81, and the movable shaft 84 is rotatably installed on the mounting structure 81. One end of the roller 20 is rotatably connected to the fixed shaft 83, and the other end of the roller 20 is fixedly connected to the movable shaft 84. One end of the elastic element 82 is connected to the fixed shaft 83, and the other end of the elastic element 82 is connected to the movable shaft 84.

[0095] The fixed shaft 83 and the movable shaft 84 provide installation positions for the two ends of the roller 20. For example, when the elastic element 82 is a coil spring, the two ends of the coil spring can be respectively sleeved and installed on the fixed shaft 83 and the movable shaft 84. When the roller 20 is rotated by an external force (i.e. the tension of the conductive element 40) to unfold the sunshade 10, it will drive the movable shaft 84 to rotate synchronously, thereby causing the elastic element 82 connected between the fixed shaft 83 and the movable shaft 84 to be torsional and deformed and store potential energy.

[0096] Optionally, such as Figure 7 and Figure 8 As shown, the sunshade device may also include a first bushing 85 and a second bushing 86. The first bushing 85 is located between the fixed shaft 83 and the roller 20, and the second bushing 86 is located between the movable shaft 84 and the mounting structure 81.

[0097] As a sliding bearing, the bushing can separate the relatively rotating shaft and the hole and provide lubrication to reduce friction. In the above specific structure, the fixed shaft 83 and the roller 20 are rotatably connected through the first shaft, which can reduce the frictional resistance of the roller 20 rotating relative to the fixed shaft 83. The movable shaft 84 and the mounting structure 81 are rotatably connected through the second bushing 86, which can reduce the frictional resistance of the movable shaft 84 rotating relative to the mounting structure 81. This can reduce the mechanical friction loss of the roller 20 during rotation, making the unfolding and rolling of the sunshade 10 smoother and easier, and helping to improve the service life of related components.

[0098] This disclosure does not limit the type of elastic element 82. As one embodiment, elastic element 82 may include a coil spring.

[0099] The coil spring can be contained within a limited space (such as inside the coil 20) and can provide a relatively uniform torque during rotation, thereby enabling efficient storage and release of elastic potential energy within a limited space, providing a smooth and continuous winding torque for the coil 20.

[0100] As another embodiment of this disclosure, the elastic element 82 may also be a torsion spring.

[0101] Optionally, such as Figure 8 and Figure 9 As shown, the fixed shaft 83 is provided with a first insertion hole 831, and the first bushing 85 is provided with a second insertion hole 851. The first insertion hole 831 and the second insertion hole 851 are used for the insertion of the pin 87, which can be pulled out.

[0102] Before the sunshade device is installed and used, the pin 87 can be inserted into the first insertion hole 831 and the second insertion hole 851, so that the rotation of the first bushing 85 and the fixed shaft 83 is locked, thereby locking the rotation of the roller 20 relative to the mounting structure 81, so that the second end of the sunshade curtain 10 connected to the conductive element 40 extends to a suitable length (at this time, the elastic element 82 has a certain pre-tightening force on the sunshade curtain 10) to facilitate installation. After the sunshade device is installed, the pin 87 can be pulled out, so that the roller 20 can rotate relative to the mounting structure 81 to roll up or unfold the sunshade curtain 10.

[0103] Optionally, such as Figure 7 and Figure 8 As shown, the roller 20 has an installation cavity 21, the elastic element 82 is located in the installation cavity 21, and the sunshade device also includes a sound-absorbing element 22, which is disposed between the cavity wall of the installation cavity 21 and the elastic element 82.

[0104] By accommodating the elastic element 82 in the mounting cavity 21, the internal space of the roller 20 can be utilized, which is beneficial to improving the structural compactness of the sunshade device. Furthermore, by placing the sound-absorbing element 22 between the cavity wall of the mounting cavity 21 and the elastic element 82, the collision and friction that may be generated between the elastic element 82 and the inner wall of the roller 20 due to relative movement can be effectively absorbed, thereby reducing or eliminating the noise and abnormal sounds generated therefrom.

[0105] Optionally, such as Figure 1 As shown, the sunshade device also includes a position detection component, which includes a transmitter 91 and a receiver 92. One of the transmitter 91 and the receiver 92 is disposed on the mounting structure 81, and the other of the transmitter 91 and the receiver 92 is disposed on the conductive element 40.

[0106] The transmitter 91 and receiver 92 are respectively mounted on the mounting structure 81 and the conductive element 40, forming a non-contact displacement or position sensing system. When the conductive element 40 moves the sunshade 10, its position relative to the fixed mounting structure 81 changes, and the signal state between the transmitter 91 and the receiver 92 changes accordingly. This information about the state change can be used by the control system (such as the vehicle control system) to detect and calculate the real-time position of the conductive element 40 (i.e., the second end of the sunshade 10), thereby enabling precise detection and positioning control of the extreme positions (such as fully unfolded or fully rolled up) or any preset intermediate positions of the sunshade 10, thus improving the level of automation and intelligence.

[0107] In one specific embodiment, the position detection component is configured as a pair of infrared through-beam sensors for accurately detecting the extreme positions of the sunshade 10 (such as fully extended and fully retracted). Its specific configuration and continuous operation process are as follows: The transmitter 91 uses an infrared emitting diode, which is directly fixedly mounted on the conductive component 40 (i.e., the movable side strip of the sunshade 10) and moves along the guide rail 50 accordingly. Two infrared receiving phototransistors, serving as receivers 92, are respectively fixedly mounted on the mounting structure 81 at the two extreme positions corresponding to the "fully extended" and "fully retracted" positions of the sunshade 10. The emitting head of the transmitter 91 and the receiving heads of the two receivers 92 are precisely aligned during installation to ensure an unobstructed signal path.

[0108] Taking the detection and positioning control of the extreme positions (such as fully expanded and fully rolled up) of the sunshade curtain 10 as an example, as an exemplary implementation, the transmitter 91 can continuously emit modulated infrared light signals. During the movement of the sunshade curtain 10 driven by the conductive member 40, the transmitter 91 moves accordingly. When the sunshade curtain 10 moves to the "fully rolled up" position, the transmitter 91 on the conductive member 40 moves exactly to the position directly opposite the receiver 92 installed in the "fully rolled up" position. At this time, the infrared light emitted by the transmitter 91 is effectively received by the receiver 92, and the electrical signal output by the receiver 92 changes state. This change signal is transmitted to the microcontroller of the sunshade device. After the microcontroller detects the signal change of the specific receiver 92, it determines that the conductive member 40 has reached the "fully rolled up" position, and then controls the circuit to cut off or reverse the current supplied to the conductive member 40, and the sunshade curtain 10 stops moving. Similarly, when the sunshade 10 moves from the rolled-up state to the unfolded state, and the transmitter 91 moves to align with another receiver 92 in the "fully unfolded" position, the receiver 92 generates a signal jump. Based on this, the microcontroller determines that the "fully unfolded" position has been reached and controls the current change to stop the sunshade 10.

[0109] According to a second aspect of this disclosure, a vehicle is provided that includes the aforementioned sunshade device.
