[0023] To make the technical problems solved, the technical solutions, and the beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0024] like Figures 1 to 3As shown, in one embodiment, the car includes a car body 10 and a sunshade device 20. The sunshade device 20 is mounted on the car body 10, which is equivalent to a car in the prior art without a sunshade device 20. The sunshade device 20 includes a bracket 1, a sunshade 2, and a first drive unit 3. The bracket 1 is mounted on the car body 10 and connected to the sunshade 2. The first drive unit 3 is mounted on the car body 10 and connected to one end of the bracket 1. The first drive unit 3 applies force to the bracket 1 to drive it to move, causing the other end of the bracket 1 to move away from or towards the car body 10. When the other end of the bracket 1 moves away from the car body 10, the bracket 1 can cause the sunshade 2 to unfold, thereby increasing the shaded area of ​​the car and providing better sun protection for people. When the other end of the bracket 1 moves towards the car body 10, the bracket 1 can cause the sunshade 2 to retract, thereby reducing the adverse effects of the sunshade device 20 on the car body 10 and allowing the car body 10 to be driven normally.

[0025] In one embodiment, the sunshade device 20 further includes a base. One end of the bracket 1 is connected to the vehicle body 10 via the base. When the first drive unit 3 applies force to the bracket 1, it can move the other end of the bracket 1 away from or towards the base, thereby causing the sunshade 2 to unfold or retract. In actual products, the base can be an independent component, connected to both the bracket 1 and the vehicle body 10. In this case, the sunshade device 20 can be manufactured and assembled independently, and then the base can be connected to the vehicle body 10 to achieve the installation of the sunshade device 20 on the vehicle body 10. Alternatively, the base and the vehicle body 10 can be an integral structure, with the base formed on the vehicle body 10. That is, in actual products, the base can be connected to or formed on the vehicle body 10.

[0026] In one embodiment, the bracket 1 is connected to or formed on the inside of the trunk door of the vehicle body 10. In this case, the bracket 1 is installed on the inside of the trunk door of the vehicle body 10. When the bracket 1 moves the sunshade 2 to retract, the sunshade 2 can be retracted to the inside of the trunk door. At this time, closing the trunk door can move the sunshade 2 and the bracket 1 into the trunk of the vehicle body 10. In this way, the setting of the sunshade device 20 will not affect the normal driving of the vehicle body 10.

[0027] In one embodiment, the inner surface of the trunk door has a recessed structure, and the base is connected to or formed within the recessed structure. When the other end of the bracket 1 is close to the vehicle body 10, it can move into the recessed structure to drive the sunshade 2 to retract into the recessed structure. This reduces the space occupied by the sunshade device 20 in the trunk and makes the vehicle neater. At the same time, the end of the bracket 1 connected to the base is also located within the recessed structure.

[0028] In one embodiment, the first drive unit 3 is connected to the control center of the vehicle body 10. The control center can control the operation of the first drive unit 3, enabling it to apply force to the bracket 1 and drive the bracket 1 to move. This allows users to control the unfolding or retraction of the awning 2 from the control panel in the control center, making the control of the awning 2 more convenient and intelligent.

[0029] like Figure 1 and Figure 3 As shown, the sunshade device 20 also includes a control unit 4. The control unit 4 is a control device independent of the vehicle body 10. The control unit 4 is used to control the operation of the first drive unit 3, so that the first drive unit 3 can drive the bracket 1 to move. That is, in this embodiment, in addition to controlling the opening or closing of the sunshade 2 through the vehicle's control center, the opening or closing of the sunshade 2 can also be controlled through the control unit 4 of the sunshade device 20 itself. When people cannot control the opening or closing of the sunshade 2 on the control panel of the vehicle body 10, they can control the opening or closing of the sunshade 2 through the control unit 4.

[0030] In addition, in actual products, the opening or closing of the sunshade 2 can be controlled by either the control center or the control unit 4. When the car has both a control center and a control unit 4, the control unit 4 can also be connected to the control center, and the control center can send control signals to the control unit 4. The control unit 4 then controls the operation of the first drive unit 3 according to the signals, thereby controlling the opening or closing of the sunshade 2.

[0031] like Figure 1 As shown, the sunshade device 20 also includes a position detection unit 5. The position detection unit 5 is used to detect whether the other end of the bracket 1 has moved to its maximum position. When the other end of the bracket 1 moves to its maximum position, the first drive unit 3 can be controlled to stop driving the bracket 1 to move. The other end of the bracket 1 moving to its maximum position includes: moving to its maximum position when the other end of the bracket 1 is away from the vehicle body 10, and moving to its maximum position when the other end of the bracket 1 is close to the vehicle body 10. When it is detected that the other end of the bracket 1 has moved to its maximum position when it is away from the vehicle body, it indicates that the sunshade has been deployed, and the control unit 4 can then stop working; when it is detected that the other end of the bracket 1 has moved to its maximum position when it is close to the vehicle body, it indicates that the sunshade has been retracted, and the control unit 4 can then stop working.

[0032] In this embodiment, the position detection unit 5 can be first connected to the control unit 4, and then connected to the control center through the control unit 4, so as to realize communication between the position detection unit 5 and the control center. Of course, in other embodiments, the position detection unit 5 can also be directly connected to the vehicle's control center to realize communication between the two.

[0033] In one embodiment, the first drive unit 3 includes a motor 31, which drives the bracket 1 to rotate, causing the other end of the bracket 1 to move closer to or further away from the vehicle body 10. Simultaneously, the sunshade device also includes a current detection unit, which detects the current in the motor 31. By detecting the current in the motor 31, it can be determined whether the motor 31 is stalled, and thus whether the bracket 1 has moved to its maximum position. The combined use of the current detection unit and the position detection unit 5 improves the reliability of position detection.

[0034] In this embodiment, the current detection unit can be first connected to the control unit 4, and then connected to the control center through the control unit 4 to achieve communication between the current detection unit and the control center. Of course, in other embodiments, the current detection unit can also be directly connected to the vehicle's control center to achieve communication between the two.

[0035] like Figure 1 and Figure 3 As shown, in one embodiment, the bracket 1 includes a first support rod 11 and a second support rod 12. The first end of the first support rod 11 is rotatably connected to the base, thereby achieving a rotatable connection with the vehicle body 10. The first end of the second support rod 12 is also rotatably connected to the base, thereby achieving a rotatable connection with the vehicle body 10. Specifically, the first support rod 11 can rotate relative to the base and the vehicle body 10 within a first plane, and the second support rod 12 can also rotate relative to the base and the vehicle body 10 within a first plane. The first plane is parallel to the axis of the first support rod 11 and parallel to the axis of the second support rod 12. A sunshade 2 is disposed between the first support rod 11 and the second support rod 12. The left and right ends of the sunshade 2 are connected to the first support rod 11 and the second support rod 12, respectively, and the lower end of the sunshade 2 is connected to the vehicle body 10.

[0036] In this embodiment, the second end of the first support rod 11 and the second end of the second support rod 12 constitute the other end of the bracket 1 described above, wherein the second end of the first support rod 11 is opposite to the first end of the first support rod 11, and the second end of the second support rod 12 is opposite to the first end of the second support rod 12.

[0037] In one embodiment, the left end of the awning 2 is connected to the first support rod 11, and the right end of the awning 2 is connected to the second support rod 12. When the first support rod 11 rotates to the left and the second support rod 12 rotates to the right, the awning 2 can be unfolded; when the first support rod 11 rotates to the right and the second support rod 12 rotates to the left, the awning 2 can be retracted.

[0038] In another embodiment, the distance between the first end of the first support rod 11 and the first end of the second support rod 12 is greater than the sum of the lengths of the first support rod 11 and the second support rod 12. This way, when the first support rod 11 and the second support rod 12 rotate relative to the vehicle body 10 in the same plane, the two support rods can also avoid collision.

[0039] Furthermore, in one embodiment, the second end of the first support rod 11 is flush with the upper end of the awning 2, and the second end of the second support rod 12 is also flush with the upper end of the awning 2. Simultaneously, each area on the left side of the awning 2 may be completely connected to the first support rod 11, and each area on the right side of the awning 2 may be completely connected to the second support rod 12.

[0040] In actual products, the awning 2 is usually made of fabric. When the two support rods retract the awning 2, the upper part of the awning 2 may not be able to retract effectively. Therefore, as... Figure 1 and Figure 3 As shown, in one embodiment, the sunshade device 20 further includes a rotating shaft 6, a cable 7, and a second drive unit 8; the rotating shaft 6 is rotatably connected to the vehicle body 10; one end of the cable 7 is connected to the rotating shaft, and the other end of the cable 7 is connected to the connecting area of ​​the sunshade 2, wherein the connecting area is located at the upper end of the sunshade 2; the second drive unit 8 is used to drive the rotating shaft 6 to rotate, so as to wind or unwind the cable 7. When the cable 7 is wound up, the cable 7 can pull the connecting area of ​​the sunshade 2 downward; when the cable 7 is unwound, the two support rods can unfold the sunshade 2. Alternatively, the second drive unit 8 can also be a motor. Preferably, the connecting area is located in the middle part of the upper end of the sunshade 2.

[0041] When the bracket 1 has a first support rod 11 and a second support rod 12, the first drive unit 3 includes two motors 31, one of which is used to drive the first support rod 11 to rotate, and the other motor 31 is used to drive the second support rod 12 to rotate.

[0042] like Figure 1 and Figure 2 As shown, the position detection unit 5 includes a first detection module 51 and a second detection module 52. The first detection module 51 is used to detect whether the first support rod 11 has rotated to the maximum position, and the second detection module 52 is used to detect whether the second support rod 12 has rotated to the maximum position.

[0043] like Figure 1 and Figure 2As shown, the first detection module 51 includes two position sensors 53, which are respectively located on the left and right sides of the first end of the first support rod 11. When the first support rod 11 rotates to its maximum left position, it will be detected by the position sensor 53 on its left side; when the first support rod 11 rotates to its maximum right position, it will be detected by the position sensor 53 on its right side. Similarly, the second detection module 52 also includes two position sensors 53, which are respectively located on the left and right sides of the first end of the second support rod 12.

[0044] Understandably, in other embodiments, the first detection module 51 can also be an angle sensor, which detects the rotation angle of the first support rod 11 to determine whether it has rotated to its maximum position. Similarly, the second detection module 52 can also be an angle sensor, which detects the rotation angle of the second support rod 12 to determine whether it has rotated to its maximum position.

[0045] Furthermore, when the first support rod 11 and the second support rod 12 are driven to move by the two motors 31 respectively, the current detection unit includes two units, and the two current monitoring units detect the current of the two motors 31 respectively.

[0046] like Figure 4 The diagram illustrates the deployment control flow of a sunshade device 20 provided in one embodiment: First, press the "Sunshade - Open" button on the control panel of the control center. At this time, the control panel communicates with the control unit 4 to obtain the status signal of the sunshade 2. If the sunshade is deployed, the control panel displays "Sunshade is open". If the sunshade status is "not open", the control center will further determine the trunk door status. If the trunk door status is "not open", the control panel reminds "Please open the trunk door first". If the trunk door status is "open", the control center sends a "Open Sunshade" command to the control unit 4. The control unit 4 executes the "Open Sunshade" command and controls the first drive unit 3 to move, thereby driving the bracket 1 to move. When the position detection unit detects that the bracket has moved away from the car body 10 to the maximum position, it indicates that the sunshade 2 has been successfully opened. At this time, the control panel displays "Sunshade is open". If the position detection unit does not detect that the bracket has moved away from the car body 10 to the maximum position, it indicates that the sunshade 2 has failed to open, and the control panel displays "Sunshade malfunction, manual opening is recommended".

[0047] like Figure 5The diagram illustrates the retraction control process of a sunshade device 20 provided in one embodiment: When the "Sunshade - Close" button is pressed on the control panel, the control panel obtains the sunshade position information by communicating with the control unit 4. If the sunshade is in the retracted state, the control panel displays "Sunshade closed". If the sunshade is not retracted, the control center sends a "Close Sunshade" command to the control unit 4. The control unit 4 executes the "Close Sunshade" action, causing the first drive unit 3 to drive the bracket 1 to move. When the position detection unit detects that the bracket 1 has moved towards the car body to the maximum position, it indicates that the sunshade has been retracted, and the control panel displays "Sunshade closed". If the position detection unit does not detect that the bracket 1 has moved towards the car body to the maximum position, it indicates that the sunshade has failed to retract, and the control panel displays "Sunshade malfunction, manual closure recommended".

[0048] In addition, the aforementioned design can also be replaced in other ways, such as:

[0049] In other embodiments, the bracket 1 may have only one support rod. In this case, the awning 2 may be a fan-shaped structure. One side of the awning 2 is connected to the vehicle body 10, and the other side of the awning 2 is connected to the support rod. When the support rod rotates relative to the vehicle body 10, the awning 2 can be unfolded or retracted. The rotation axis of the support rod relative to the vehicle body 10 is coaxial with that of the awning 2. Furthermore, in the fan shape obtained by the orthographic projection of the awning 2 onto a plane, the projections of the two sides of the awning 2 are the two sides of the central angle of the fan.

[0050] In other embodiments, the motor described above can also be replaced by a rotary cylinder or the like.

[0051] In other embodiments, the sunshade device 20 may also be installed on the side wall or roof of the vehicle body 10.

[0052] In other embodiments, the bracket 1 can also extend or retract the awning 2 by means of length extension and retraction. In this case, the bracket 1 can be a folding structure or a guide rail structure.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
