[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0027] See Figures 1 to 7 This application provides a car door sunshade and the car thereof, which can solve the problem in the related technology that commercial vehicle door sunshades cannot be adapted to irregular door frames due to the limitation of the curtain structure, resulting in triangular light leakage areas.

[0028] Commercial vehicle door sunshades are used to block side sunlight from entering through the door glass. They are usually installed on the side panel or door and the curtain is retracted by pulling it up and down. Door sunshades generally use fixed width sunshade curtains, which cannot cover the entire door area. Furthermore, due to the limitations of the curtain structure, commercial vehicle door sunshades cannot be adapted to irregularly shaped door frames, resulting in triangular light leakage areas.

[0029] To address the issue of triangular light leakage areas in commercial vehicle door sunshades due to their inability to adapt to irregularly shaped door frames caused by the fabric structure limitations, this application provides a door sunshade comprising: a frame 1, a main sunshade assembly 2, and an auxiliary sunshade assembly 3. The main sunshade assembly 2 is mounted on the frame 1 and includes a main sunshade curtain 24 and an operating component. The operating component is connected to the main sunshade curtain 24 and is used to drive the main sunshade curtain 24 to unfold to cover a first area of ​​the window. The auxiliary sunshade assembly 3 is mounted on the frame 1 and located on one side of the main sunshade assembly 2. The auxiliary sunshade assembly 3 includes an auxiliary sunshade curtain 31, which is connected to the operating component. The operating component is used to drive the auxiliary sunshade curtain 31 to unfold to cover a triangular area of ​​the window.

[0030] In this application, the car door sunshade can be adapted to car windows of any angle and shape. The main sunshade assembly 2 and the auxiliary sunshade assembly 3 can block the first area and the triangular area of ​​the car window to cover the entire area of ​​the car window. At the same time, when the operating component in the main sunshade assembly 2 is working, it can drive the main sunshade 24 and the auxiliary sunshade 31 to open simultaneously, so that the main sunshade assembly 2 and the auxiliary sunshade assembly 3 can be mechanically linked, which is convenient for operation.

[0031] When the control unit is activated, the main sunshade 24 can cover the first area of ​​the window, while the auxiliary sunshade 31 unfolds to cover the triangular area of ​​the window, thus blocking the triangular light leakage area on the window.

[0032] The frame 1 can be made of nylon to make the device lighter and easier to install. It does not have a large metal shell. The nylon frame 1 is installed in the door trim cover as a whole, so that the device is small in size and can be integrated and hidden in the door trim cover to achieve the effect of hiding the appearance.

[0033] Furthermore, the frame 1 includes: a skeleton 10, a first guide rail 11, and a second guide rail 12. The skeleton 10 is made of nylon and has an overall "n"-shaped structure, meaning that the skeleton 10 includes a horizontal bar and two vertical bars located on both sides of the horizontal bar and integrally formed with it. The skeleton 10 provides a mounting base for other structures to ensure the overall strength of the car door sunshade. When the main sunshade 24 is retracted, it is located at the bottom of the horizontal bar. The first guide rail 11 is located on one side of the skeleton 10. Specifically, a first mounting point is provided on one of the vertical bars, and the first guide rail 11 is fixed to the skeleton 10 at the first mounting point by a mounting seat 13. The second guide rail 12 is located on the other side of the skeleton 10. Specifically, a second mounting point is provided on the other vertical bar, and the second guide rail 12 is fixed to the skeleton 10 at the second mounting point by a mounting seat 13.

[0034] Based on the above embodiments, in this embodiment, the operating component is movably connected to the first guide rail 11.

[0035] The operating components include: a spring mechanism and a pull rod 25.

[0036] The elastic mechanism is mounted on the frame 1. One end of the main sunshade 24 is connected to the elastic mechanism and wrapped around its outer surface. When the main sunshade 24 is unfolded, the elastic mechanism undergoes elastic deformation and begins to move to cooperate with the unfolding of the main sunshade 24. When the main sunshade 24 is retracted, the elastic mechanism rebounds, causing the main sunshade 24 to retract.

[0037] Furthermore, the elastic mechanism includes: a connecting shaft 21, a rotating shaft 20, and a spring 22. The connecting shaft 21 is fixed to the frame 1; the rotating shaft 20 is sleeved on the outer peripheral surface of the connecting shaft 21; the spring 22 is disposed between the connecting shaft 21 and the rotating shaft 20, and one end of the spring 22 is fixed to the connecting shaft 21, and the other end is fixed to the rotating shaft 20.

[0038] In this embodiment, the spring 22 can be a variable cross-section spring 22. The spring 22 and the connecting shaft 21 are fixed together by a limiting member 23, wherein the limiting member 23 can be a limiting rubber ring. The variable cross-section spring 22 and the connecting shaft 21 are fixedly connected at the limiting rubber ring. The connecting shaft 21 is located near the top of the first guide rail 11. The connecting shaft 21 and the mounting seat 13 on the first guide rail 11 are fixed together by a wedge structure. A retaining ring 220 is also connected between the connecting shaft 21 and the mounting seat 13 on the first guide rail 11, so the connecting shaft 21 cannot rotate.

[0039] The rotating shaft 20 can be made of aluminum alloy. An end cap 28 is fixed to the end of the rotating shaft 20 via a protrusion, and one end of the variable cross-section spring 22 is fixedly connected to the end cap 28, thus fixing the variable cross-section spring 22 to the rotating shaft 20. Since the spring 22 is fixed to the connecting shaft 21 by a limiting rubber ring, the spring 22 remains stationary at the limiting rubber ring end. The other end of the spring 22 is fixedly connected to the rotating shaft 20 via the end cap 28. Therefore, when the rotating shaft 20 rotates, the end of the spring 22 closest to the end cap 28 rotates accordingly. This achieves the effect of one side being fixed and the other side rotating to obtain elastic force. Furthermore, the spring 22 can be pre-rotated several turns to provide preload.

[0040] The pull rod 25 is movably mounted on the frame 1, meaning that the pull rod 25 is movably connected to the first guide rail 11. Specifically, a first guide groove is provided on the first guide rail 11 in the frame 1, and one end of the pull rod 25 in the operating component is movably connected to the first guide groove, that is, the pull rod 25 slides in the first guide groove; and the other end of the pull rod 25 is connected to the main sunshade 24, that is, when the pull rod 25 is pulled down, the pull rod 25 is used to drive the main sunshade 24 to unfold.

[0041] The two ends of the main sunshade 24 are glued to the pivot 20 and the pull rod 25 with strong adhesive. The rotation of the pivot 20 can cause the main sunshade 24 to roll up or unfold. A handle 29 is fixed on the pull rod 25. A person can operate the handle 29 to move the pull rod 25.

[0042] Based on the above embodiments, in this embodiment, a telescopic rod 26 is provided at one end of the pull-down rod 25, and the telescopic rod 26 is movably mounted on the frame 1. Specifically, the telescopic rod 26 passes through the pull-down rod 25, and end caps 28 are fixed at both ends of the telescopic rod 26, and are slidably connected to the first guide rail 11 and the second guide rail 12. Because of the telescopic rod 26, the car door sunshade can adapt to car windows of different widths after the telescopic rod 26 extends or retracts.

[0043] Furthermore, the operating component is provided with a locking component 27, which is used to lock the operating component to the frame 1 or unlock it from the frame 1.

[0044] Specifically, the locking member 27 includes a rubber ring, which is positioned within the first guide groove. In this embodiment, the width of the rubber ring is smaller than the width of the first guide groove, and the length of the rubber ring is greater than the width of the first guide groove. When the rubber ring abuts against the inner wall of the first guide groove, that is, when the pull rod 25 is rotated to make the rubber ring horizontal, i.e., both sides of the rubber ring abut against the inner wall of the first guide groove along its length, the pull rod 25 in the operating member is locked onto the frame 1, and the main sunshade 24 cannot continue to unfold or close. When there is a gap between the rubber ring and the inner wall of the first guide groove, that is, when the pull rod 25 is rotated to make the rubber ring vertical, i.e., there is a gap between the two sides of the rubber ring along its width and the inner wall of the first guide groove, the pull rod 25 in the operating member is unlocked from the frame 1, and the main sunshade 24 can continue to unfold or close.

[0045] Based on the above embodiments, in this embodiment, the auxiliary sunshade component 3 is connected to the second guide rail 12. Specifically, the auxiliary sunshade component 3 includes: a connecting rod 30, which is rotatably connected to the frame 1; the operating component is connected to the connecting rod 30 and is used to drive the connecting rod 30 to rotate, so that the auxiliary sunshade curtain 31 can be unfolded or retracted.

[0046] The frame 1 is provided with a second guide groove, that is, the second guide rail 12 is provided with a second guide groove, and the second guide groove passes through one side of the second guide rail 12 in the frame 1; one end of the connecting rod 30 passes through the second guide groove and is rotatably connected to the outer wall of the frame 1. More specifically, the bottom end of the connecting rod 30 is rotatably connected to the second guide rail 12 near the bottom end.

[0047] The telescopic rod 26 in the operating component is movably connected at one end to the second guide groove. An end cap 28 is also provided at the other end of the telescopic rod 26, and a rubber ring is also provided on the end cap 28. In this embodiment, the width of the rubber ring is smaller than the width of the second guide groove, and the length of the rubber ring is greater than the width of the second guide groove. When the rubber ring abuts against the inner wall of the second guide groove, that is, when the pull rod 25 is rotated to make the rubber ring horizontal, i.e., both sides of the rubber ring abut against the inner wall of the second guide groove in the length direction, the pull rod 25 in the operating component is locked onto the frame 1, and the auxiliary sunshade 31 cannot continue to unfold or close. When there is a gap between the rubber ring and the inner wall of the second guide groove, that is, when the pull rod 25 is rotated to make the rubber ring vertical, i.e., there is a gap between both sides of the rubber ring in the width direction and the inner wall of the second guide groove, the pull rod 25 in the operating component is unlocked from the frame 1, and the auxiliary sunshade 31 can continue to unfold or close.

[0048] The auxiliary sunshade curtain 31 can be a folding fan, with one end fixed to the connecting rod 30 and the other end fixed to the second guide rail 12. One end of the connecting rod 30 is rotatably connected to one side of the second guide rail 12 via a rotating shaft 20.

[0049] In some possible embodiments, the other end of the connecting rod 30 rotates freely around the pivot 20 and rests on the pull rod 25. When the operator pulls down the handle 29, causing the pull rod 25 to move downward, the connecting rod 30 rotates around the pivot 20, opening the folding fan. When the main sunshade 24 retracts, the pull rod 25 moves upward due to the pre-tensioning force, causing the connecting rod 30 to rotate clockwise around the pivot 20, and the auxiliary sunshade 31 retracts. When the auxiliary sunshade 31 is fully extended, the pull rod 25 in the operating mechanism is located at the bottom end of the connecting rod 30.

[0050] In some other possible embodiments, a groove is provided at the end of the connecting rod away from the auxiliary sunshade 31, and one end of the telescopic rod 26 is slidably connected in the groove via a hinge. When the pull rod 25 moves downward, it drives the connecting rod 30 to rotate around the pivot 20, causing the folding fan to open. When the main sunshade 24 is retracted, the pull rod 25 moves upward due to the pre-tensioning force, driving the connecting rod 30 to rotate clockwise around the pivot 20, and the auxiliary sunshade 31 is retracted. When the auxiliary sunshade 31 is fully unfolded, the pull rod 25 in the operating component is located at the bottom end of the connecting rod 30.

[0051] The above embodiments are merely various possible implementations of the embodiments of this application, and the embodiments of this application are not limited thereto.

[0052] In summary, the car door sunshade has an unfolded state and a rolled-up state for the main sunshade 24 and the auxiliary sunshade 31.

[0053] The process from the unfolded state of the main sunshade 24 and the auxiliary sunshade 31 to the rolled-up state of the main sunshade 24 and the auxiliary sunshade 31 is the pulling-down process: when pulling down, the hard plastic handle 29 is pulled downwards. First, the pull rod 25 is rotated by the handle 29, causing the pull rod 25 to unlock from the frame 1. Specifically, as the pull rod 25 rotates, the aluminum alloy pull rod 25 drives the elliptical end cap 28 and the elliptical telescopic rod 26 to rotate. The rubber rings on both sides of the telescopic rod 26 rotate synchronously and disengage from the side walls of the first guide rail 11 and the second guide rail 12, eliminating the locking friction and causing the main sunshade 24 to descend and cover the first area of ​​the window. At the same time as the elliptical telescopic rod 26 moves downwards, the connecting rod 30 drives the auxiliary sunshade 31 to rotate around the rotation axis 20. After the auxiliary sunshade 31 unfolds, it covers the triangular area of ​​the window. When the lever is pulled down to the position designated by the driver, the handle 29 is released and the lever 25 is rotated in the opposite direction, so that the rubber rings on both sides of the telescopic rod 26 rotate synchronously and re-abut against the side walls of the first guide rail 11 and the second guide rail 12. The increased friction between the rubber rings and the first guide rail 11 and the second guide rail 12 achieves locking.

[0054] The process of changing from the rolled-up state of the main sunshade curtain 24 and the auxiliary sunshade curtain 31 to the unfolded state of the main sunshade curtain 24 and the auxiliary sunshade curtain 31 is a pulling-down process:

[0055] During retrieval, the handle 29, made of hard plastic, is pulled manually (same as the pull-down operation). Then, the handle 29 rotates, and the pull-down rod 25, made of aluminum alloy, rotates. The pull-down rod 25 drives the elliptical end cap 28 and the elliptical telescopic rod 26 to rotate. The rubber rings on both sides of the telescopic rod 26 rotate synchronously and disengage from the side walls of the first guide rail 11 and the second guide rail 12, eliminating the locking friction. The pull-down rod 25 is retracted by the pre-tension force provided by the variable cross-section spring 22 inside the top aluminum alloy rotating shaft 20. At the same time, the elliptical telescopic rod 26 drives the connecting rod 30 and the auxiliary sunshade 31 to retract around the rotating shaft 20 (similar to the folding process of a folding fan). The elliptical telescopic rod 26 retracts into the pull-down rod 25 because the distance between the first guide rail 11 and the second guide rail 12 shortens during retrieval. When the main sunshade 24 is retracted to the top, the pull rod 25 is rotated in the opposite direction, causing the rubber rings on both sides of the telescopic rod 26 to rotate synchronously and re-abut against the side walls of the first guide rail 11 and the second guide rail 12. The increased friction between the rubber rings and the first guide rail 11 and the second guide rail 12 achieves locking.

[0056] In summary, the car door sunshade in this application includes a main sunshade component 2 and an auxiliary sunshade component 3. The main sunshade component 2 and the auxiliary sunshade component 3 are mechanically linked during movement. The auxiliary sunshade component 3 is integrated with the main sunshade component 2 without occupying extra space. At the same time, the main sunshade 24 and the auxiliary sunshade 31 can be adapted to car windows of any angle and shape, with no light leakage area, and can achieve 100% sun shading.

[0057] With the pull rod 25 working in conjunction with the telescopic rod 26, the telescopic rod 26 can adapt to window structures with unequal widths at the top and bottom during the downward movement of the main sunshade 24. Simultaneously, locking is achieved through friction between the locking element 27 and the first guide rail 11 and the second guide rail 12 on both sides. The user only needs to rotate the handle 29 and the pull rod 25 to stop the movement easily.

[0058] The frame 1, made of a single piece of nylon, is small in size and can be hidden inside the door trim cover for concealed installation.

[0059] Secondly, this application provides an automobile, which includes: a door sunshade and a window provided in any of the above embodiments of this application, wherein the window is provided with a first area and a triangular area, the main sunshade component 2 is located in the first area, and the auxiliary sunshade component 3 is located in the triangular area.

[0060] In this application, the car door sunshade can be adapted to car windows of any angle and shape. The main sunshade assembly 2 and the auxiliary sunshade assembly 3 can block the first area and the triangular area of ​​the car window to cover the entire area of ​​the car window. At the same time, when the operating component in the main sunshade assembly 2 is working, it can drive the main sunshade 24 and the auxiliary sunshade 31 to open simultaneously, so that the main sunshade assembly 2 and the auxiliary sunshade assembly 3 can be mechanically linked, which is convenient for operation.

[0061] The car door sunshade has an unfolded state and a rolled-up state for the main sunshade 24 and the auxiliary sunshade 31.

[0062] The process from the unfolded state of the main sunshade 24 and the auxiliary sunshade 31 to the rolled-up state of the main sunshade 24 and the auxiliary sunshade 31 is the pulling-down process: when pulling down, the hard plastic handle 29 is pulled downwards. First, the pull rod 25 is rotated by the handle 29, causing the pull rod 25 to unlock from the frame 1. Specifically, as the pull rod 25 rotates, the aluminum alloy pull rod 25 drives the elliptical end cap 28 and the elliptical telescopic rod 26 to rotate. The rubber rings on both sides of the telescopic rod 26 rotate synchronously and disengage from the side walls of the first guide rail 11 and the second guide rail 12, eliminating the locking friction and causing the main sunshade 24 to descend and cover the first area of ​​the window. At the same time as the elliptical telescopic rod 26 moves downwards, the connecting rod 30 drives the auxiliary sunshade 31 to rotate around the rotation axis 20. After the auxiliary sunshade 31 unfolds, it covers the triangular area of ​​the window. When the lever is pulled down to the position designated by the driver, the handle 29 is released and the lever 25 is rotated in the opposite direction, so that the rubber rings on both sides of the telescopic rod 26 rotate synchronously and re-abut against the side walls of the first guide rail 11 and the second guide rail 12. The increased friction between the rubber rings and the first guide rail 11 and the second guide rail 12 achieves locking.

[0063] The process of changing from the rolled-up state of the main sunshade curtain 24 and the auxiliary sunshade curtain 31 to the unfolded state of the main sunshade curtain 24 and the auxiliary sunshade curtain 31 is a pulling-down process:

[0064] During retrieval, the handle 29, made of hard plastic, is pulled manually (same as the pull-down operation). Then, the handle 29 rotates, and the pull-down rod 25, made of aluminum alloy, rotates. The pull-down rod 25 drives the elliptical end cap 28 and the elliptical telescopic rod 26 to rotate. The rubber rings on both sides of the telescopic rod 26 rotate synchronously and disengage from the side walls of the first guide rail 11 and the second guide rail 12, eliminating the locking friction. The pull-down rod 25 is retracted by the pre-tension force provided by the variable cross-section spring 22 inside the top aluminum alloy rotating shaft 20. At the same time, the elliptical telescopic rod 26 drives the connecting rod 30 and the auxiliary sunshade 31 to retract around the rotating shaft 20 (similar to the folding process of a folding fan). The elliptical telescopic rod 26 retracts into the pull-down rod 25 because the distance between the first guide rail 11 and the second guide rail 12 shortens during retrieval. When the main sunshade 24 is retracted to the top, the pull rod 25 is rotated in the opposite direction, causing the rubber rings on both sides of the telescopic rod 26 to rotate synchronously and re-abut against the side walls of the first guide rail 11 and the second guide rail 12. The increased friction between the rubber rings and the first guide rail 11 and the second guide rail 12 achieves locking.

[0065] In summary, the car door sunshade in this application includes a main sunshade component 2 and an auxiliary sunshade component 3. The main sunshade component 2 and the auxiliary sunshade component 3 are mechanically linked during movement. The auxiliary sunshade component 3 is integrated with the main sunshade component 2 without occupying extra space. At the same time, the main sunshade 24 and the auxiliary sunshade 31 can be adapted to car windows of any angle and shape, with no light leakage area, and can achieve 100% sun shading.

[0066] With the pull rod 25 working in conjunction with the telescopic rod 26, the telescopic rod 26 can adapt to window structures with unequal widths at the top and bottom during the downward movement of the main sunshade 24. Simultaneously, locking is achieved through friction between the locking element 27 and the first guide rail 11 and the second guide rail 12 on both sides. The user only needs to rotate the handle 29 and the pull rod 25 to stop the movement easily.
