Description

Sunshade assembly, glass assembly and vehicle

[0001] This disclosure claims priority to Chinese patent application filed on November 4, 2024, with application number 202411559752.1 and entitled "Sunshade Assembly, Glass Assembly and Vehicle", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application belongs to the field of sunshade technology, specifically relating to sunshade assemblies, glass assemblies, and vehicles. Background Technology

[0003] In existing car sunroof sunshades, the opening and closing of the curtain is typically controlled by a motor. For example, the motor pulls a steel cable, which is fixedly connected to sliders on opposite sides of the curtain. The motor pulls the steel cable to control the sliders, which in turn move the curtain, thus opening and closing it. However, currently, the two sliders on opposite sides of the curtain sometimes slide out of sync, meaning they cannot align. Adjusting the relative positions of the two sliders in this case requires disassembling the motor and many other components, making the adjustment quite difficult. Summary of the Invention

[0004] In view of this, the first aspect of this application provides a sunshade assembly, which includes a retraction assembly, a curtain fabric, two first synchronous pulleys, two synchronous belts, two sliders, and two synchronizing elements. One end of the curtain fabric is fixed to the retraction assembly, and the two first synchronous pulleys are located at opposite ends of the retraction assembly, and the two first synchronous pulleys are rotatable relative to the retraction assembly. Each synchronous belt is respectively sleeved on one of the first synchronous pulleys, each slider is respectively fixed on one of the synchronous belts, and the two sliders are fixed on opposite sides of the other end of the curtain fabric.

[0005] The two synchronizing elements are located at opposite ends of the winding assembly, and each synchronizing element is detachably connected to the winding assembly and the first synchronizing wheel located on the same side as the synchronizing element. When the synchronizing element connects the winding assembly and the first synchronizing wheel, the winding assembly and the first synchronizing wheel can rotate synchronously.

[0006] The winding assembly has two first connecting parts at opposite ends, each first synchronizing wheel has a second connecting part, and each synchronizing element has a third connecting part. The third connecting part is detachably connected to the first connecting part and the second connecting part.

[0007] The two first synchronous pulleys are sleeved on opposite ends of the winding assembly. The first connecting part includes a first slot, the second connecting part includes a second slot, and the third connecting part includes a locking block. The locking block is inserted into and removed from the first slot and the second slot.

[0008] The winding assembly has a through hole in the axial direction. The inner wall of the winding assembly and the outer wall of the synchronizing member are connected by a third slot and a buckle. The third slot is located on one of the inner wall of the winding assembly and the outer wall of the synchronizing member, and the buckle is located on the other of the inner wall of the winding assembly and the outer wall of the synchronizing member.

[0009] The sunshade assembly further includes a drive component, which is detachably connected to a synchronization component. The drive component can drive the synchronization component to rotate, thereby driving the winding assembly and the first synchronization wheel to rotate.

[0010] The winding assembly includes a spool and a support member. The support member is inserted into the spool. Each of the synchronization members is detachably connected to the support member and the first synchronization wheel located on the same side as the synchronization member.

[0011] The winding assembly further includes a fixing member, which is disposed inside the reel and fixed between the support member and the reel.

[0012] The fixing member is elastic. When the winding assembly rotates, the angle of rotation of the roller is different from the angle of rotation of the support member, so that the fixing member is in a deformed state, thereby allowing the roller to rotate relative to the support member, and thus making the moving distance of the curtain the same as the moving distance of the slider.

[0013] The synchronous belt is provided with a first engagement part, and the first synchronous pulley is provided with a second engagement part. The first engagement part and the second engagement part cooperate with each other to connect the synchronous belt and the first synchronous pulley.

[0014] The slider has a fixing groove on the side opposite to the other end of the curtain, and part of the timing belt is fixed in the fixing groove.

[0015] The synchronous belt is provided with a first engagement part, and the groove wall of the fixing groove is provided with a third engagement part. The first engagement part and the third engagement part cooperate with each other to fix the slider to the synchronous belt.

[0016] The slider includes a body and a cover plate. The body is provided with the fixing groove, and the cover plate is detachably connected to the body and can cover the fixing groove.

[0017] The sunshade assembly further includes a first support beam and two first fixing seats. The two first fixing seats are fixed to the opposite ends of the first support beam. The retraction assembly is disposed between the two first fixing seats, and the opposite ends of the retraction assembly pass through the two first fixing seats.

[0018] The sunshade assembly further includes two guide rails, which are located at opposite ends of the retractable assembly and are angled to each other. Each guide rail is fixed to a first fixing seat and has a groove, in which the slider can slide.

[0019] The first fixed base is provided with a limiting member, which is located on one side of the slide groove in the extension direction of the slide groove, and the slider can abut against the limiting member.

[0020] The limiting member is provided with a first limiting part, and the slider is provided with a second limiting part. The first limiting part and the second limiting part cooperate with each other to limit the slider to the limiting member.

[0021] The distance between the limiting member and the guide rail is greater than the length of the slider along the extension direction of the groove.

[0022] The synchronous belt and the slider located on one side of the first synchronous pulley are disposed in the groove, and the synchronous belt located on the other side of the first synchronous pulley is located outside the groove; the sunshade assembly also includes a second synchronous pulley, which is disposed on the side of the guide rail opposite to the first synchronous pulley, and the synchronous belt is also sleeved on the second synchronous pulley.

[0023] A second aspect of this application provides a glass assembly including glass and a sunshade assembly as provided in the first aspect of this application, the sunshade assembly being fixed to one side of the glass.

[0024] A third aspect of this application provides a vehicle comprising a body and a glass assembly as provided in the second aspect of this application, the glass assembly being mounted on the body.

[0025] The sunshade assembly, glass assembly, and vehicle provided in this application, through the setting of a synchronizing element, enable the two first synchronizing pulleys to rotate synchronously. Furthermore, after the synchronizing element is removed, the first synchronizing pulleys can rotate independently, thereby allowing the two first synchronizing pulleys to rotate relative to each other. Consequently, the two sliders connected to the two first synchronizing pulleys via a timing belt can also achieve synchronous or relative movement.

[0026] In related technologies, the sliders of the sunshade assembly are difficult to adjust after assembly. Therefore, the sunshade assembly provided in this application allows the sliders to pull the curtain fabric in a stable opening and closing motion when the two sliders move synchronously. When the two sliders are not aligned, this embodiment can adjust the relative position of the two sliders by disassembling the synchronizing component, causing the two first synchronizing wheels to rotate relative to each other, thereby realigning the two sliders.

[0027] In summary, this application reduces the difficulty of adjusting misaligned sliders and lowers the operational cost of adjusting their relative positions, thus making it easier and faster to analyze and resolve aftermarket quality issues. Simultaneously, it improves the stability of the curtain opening and closing process, reduces noise during curtain movement, and enhances vehicle comfort. Attached Figure Description

Detailed Implementation

[0050] The following are preferred embodiments of this application. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.

[0051] In view of this, in order to solve the above problems, this application provides a sunshade assembly. Please refer to Figures 1-7 together. Figure 1 is a schematic diagram of a sunshade assembly according to an embodiment of this application. Figure 2 is a partially exploded view of the sunshade assembly shown in Figure 1.

[0052] The sunshade assembly 1 provided in this embodiment includes a roll-up assembly 10, a curtain fabric 20, two first synchronous pulleys 21, two synchronous belts 22, two sliders 23, and two synchronizing members 24. One end of the curtain fabric 20 is fixed to the roll-up assembly 10. The two first synchronous pulleys 21 are located at opposite ends of the roll-up assembly 10, and the two first synchronous pulleys 21 are rotatable relative to the roll-up assembly 10. Each synchronous belt 22 is respectively sleeved on one of the first synchronous pulleys 21, and each slider 23 is respectively fixed on one of the synchronous belts 22, and the two sliders 23 are fixed on opposite sides of the other end of the curtain fabric 20. The two synchronizing members 24 are located at opposite ends of the roll-up assembly 10, and each synchronizing member 24 is detachably connected to the roll-up assembly 10 and the first synchronous pulley 21 located on the same side as the synchronizing member 24. When the synchronizing member 24 connects the roll-up assembly 10 and the first synchronous pulley 21, the roll-up assembly 10 and the first synchronous pulley 21 can rotate synchronously.

[0053] The sunshade assembly 1 provided in this embodiment is mainly used on the roof of various vehicles 3. The movement of the curtain 20 is controlled by a motor, so that the curtain 20 can either cover or expose the glass 40 on the roof of the vehicle 3. Of course, the sunshade assembly 1 provided in this embodiment can also be applied to other scenarios, such as residential windows, outdoor awnings, etc. This embodiment is only used to illustrate the application of the sunshade assembly 1 to the sunroof of a vehicle 3.

[0054] The sunshade assembly 1 mainly includes a retraction assembly 10, a curtain fabric 20, two first synchronous pulleys 21, two synchronous belts 22, two sliders 23, and two synchronous components 24. The retraction assembly 10 is mainly used to support, load, and fix the curtain fabric 20, and the retraction assembly 10 can rotate. Optionally, the retraction assembly 10 can be driven by an electric component, for example, the retraction assembly 10 can be connected to a motor, and the motor drives the retraction assembly 10 to rotate. The rotation of the retraction assembly 10 can also be manually driven, for example, by manually pulling a zipper, thereby causing the zipper to drive the retraction assembly 10 to rotate.

[0055] The curtain 20 is mainly used to block light, therefore it can also be called a sunshade curtain. Optionally, in this embodiment, the curtain 20 can be a semi-transparent curtain 20 or an opaque curtain 20. Simultaneously, the curtain 20 can also be used as a projection screen, therefore it can also be called a screen. One end of the curtain 20 is fixed to the retraction assembly 10, and the curtain 20 is wound around the retraction assembly 10. When the retraction assembly 10 rotates in one direction, for example clockwise, the retraction assembly 10 releases the curtain 20, and the curtain 20 gradually unfolds under the action of other components. At this time, the sunshade curtain assembly is in a light-blocking state. When the retraction assembly 10 rotates in another direction, for example counterclockwise, the curtain 20 is wound around the retraction assembly 10, thereby retracting the curtain 20. At this time, the sunshade curtain assembly is in a light-transmitting state.

[0056] Optionally, in this embodiment, the curtain fabric 20 may also be provided with side strips 30 on opposite sides. The side strips 30 are fixed to the edge of the curtain fabric 20, and the hardness of the side strips 30 is greater than that of the curtain fabric 20. When the curtain fabric 20 is unfolded, the side strips 30 can reduce the wrinkles of the curtain fabric 20, making the curtain fabric 20 flatter when unfolded.

[0057] The first synchronizing pulley 21 is mainly used to be mounted on the winding assembly 10 and to move in coordination with the winding assembly 10. In this embodiment, there are two first synchronizing pulleys 21, which are respectively mounted on opposite ends of the winding assembly 10. That is, as shown in Figure 1, one first synchronizing pulley 21 is mounted on the left end of the winding assembly 10, and the other first synchronizing pulley 21 is mounted on the right end of the winding assembly 10. It is worth noting that the first synchronizing pulley 21 can be directly mounted on the winding assembly 10. For example, the two first synchronizing pulleys 21 can be respectively fitted onto the two ends of the winding assembly 10. Alternatively, the first synchronizing pulley 21 can not be mounted on the winding assembly 10, but can be fixed to the two ends of the winding assembly 10 by other means. In other words, there is a certain gap between the first synchronizing pulley 21 and the winding assembly 10, and the first synchronizing pulley 21 is connected to the winding assembly 10 by other components.

[0058] Meanwhile, each of the first synchronizing pulleys 21 can rotate independently relative to the take-up assembly 10, or it can rotate synchronously with the take-up assembly 10 through other components. That is to say, the two first synchronizing pulleys 21 on both sides can rotate synchronously or rotate relative to each other. The conditions for switching between the two situations will be described later in this embodiment.

[0059] The synchronous belt 22 is mainly used to be fitted onto the first synchronous pulley 21 and to move in coordination with the first synchronous pulley 21. In this embodiment, there are two synchronous belts 22, each fitted onto one of the first synchronous pulleys 21. That is, as shown in Figure 1, one synchronous belt 22 is fitted onto the left first synchronous pulley 21, and the other synchronous belt 22 is fitted onto the right first synchronous pulley 21. Furthermore, the synchronous belt 22 is also connected to the first synchronous pulley 21; in other words, when the first synchronous pulley 21 rotates, it drives the synchronous belt 22 to move synchronously.

[0060] Optionally, in this embodiment, the synchronous belt 22 is a closed-loop synchronous belt, that is, the synchronous belt 22 is a closed ring, rather than a straight line like an open synchronous belt. This avoids the problem of needing to connect both ends simultaneously when installing an open synchronous belt, making the installation of the synchronous belt 22 more convenient. Of course, in other embodiments, the synchronous belt 22 can also be an open synchronous belt. This embodiment is only used as an illustrative example of a closed-loop synchronous belt 22.

[0061] The slider 23 is mainly used to pull the curtain fabric 20. In this embodiment, there are two sliders 23, which are fixed to opposite sides of the other end of the curtain fabric 20. That is, the sliders 23 are fixed to opposite sides of the end of the curtain fabric 20 away from the winding assembly 10. In other words, as shown in Figure 1, one slider 23 is fixed to the left side of the curtain fabric 20, and the other slider 23 is fixed to the right side of the curtain fabric 20. At the same time, the sliders 23 are also fixed to the timing belt 22, so that when the timing belt 22 moves, the sliders 23 move with the timing belt 22.

[0062] As can be seen from the above, the synchronous belt 22 is connected to the first synchronous pulley 21, and the slider 23 is fixed to the first synchronous belt 22. That is, when the first synchronous pulley 21 rotates, the first synchronous pulley 21 drives the synchronous belt 22 to move, and the synchronous belt 22 drives the slider 23 to move, thereby realizing the synchronous movement of the first synchronous pulley 21 and the slider 23. As for the specific fixing method between the synchronous belt 22, the first synchronous pulley 21 and the slider 23, this embodiment will be described in detail later.

[0063] Specifically, during the unfolding process of the curtain 20, the curtain 20 is mainly moved by the sliders 23 fixed to the opposite sides of the other end of the curtain 20. During the retraction process of the curtain 20, the curtain 20 is mainly wound around the retraction assembly 10 by the rotation of the retraction assembly 10. At this time, the sliders 23 are used to assist in pulling the curtain 20, so that the curtain 20 remains flat during the winding process.

[0064] Optionally, the sunshade assembly 1 in this embodiment may further include a pull rod 31. The pull rod 31 is fixed to the end of the curtain 20 away from the retractor assembly 10, and the side of the curtain 20 away from the retractor assembly 10 is also fixed to the pull rod 31. Simultaneously, both ends of the pull rod 31 are fixed to sliders 23 on both sides, so that the sliders 23 indirectly pull the curtain 20 through the pull rod 31. By providing the pull rod 31, the curtain 20 is made more flat and aesthetically pleasing when unfolded.

[0065] Alternatively, the pull rod 31 and the slider 23 can be fixed by a plug-in connection. For example, the slider 23 has a plug on the side facing the pull rod 31, and the pull rod 31 has a slot on the side facing the slider 23. When the plug is inserted into the slot, the plug and the slot are interference-fitted, so that the plug is stably inserted into the slot, thereby fixing the pull rod 31 between the two sliders 23. Fixing the pull rod 31 and the slider 23 by plugging in makes the installation and disassembly process more convenient.

[0066] The synchronizing element 24 is mainly used to switch the first synchronizing pulley 21 and the take-up assembly 10 between synchronous rotation and relative rotation. In this embodiment, there are two synchronizing elements 24, which are respectively set at opposite ends of the take-up assembly 10, as shown in Figure 1. One synchronizing element 24 is set on the left side of the take-up assembly 10, and the other synchronizing element 24 is set on the right side of the take-up assembly 10. The synchronizing element 24 is detachably connected to the take-up assembly 10 and the first synchronizing pulley 21 located on the same side as the synchronizing element 24. That is, when the synchronizing element 24 connects the first synchronizing pulley 21 and the take-up assembly 10, the rotation of the take-up assembly 10 will drive the synchronizing element 24 to rotate. At the same time, the rotation of the synchronizing element 24 will drive the first synchronizing pulley 21 to rotate, so that the take-up assembly 10 and the first synchronizing pulley 21 can rotate synchronously.

[0067] When the synchronizing element 24 is detached from the take-up assembly 10 and the first synchronizing pulley 21, the take-up assembly 10 is disconnected from the first synchronizing pulley 21. At this time, the take-up assembly 10 and the first synchronizing pulley 21 cannot rotate synchronously. In other words, the first synchronizing pulley 21 can rotate relative to the take-up assembly 10. Optionally, in this embodiment, the synchronizing element 24 can be a bushing, pin, or other component. The specific structure of the synchronizing element 24 will be described in detail later in this embodiment.

[0068] As can be seen from the above, when the synchronizing element 24 connects the first synchronizing pulley 21 to the winding assembly 10, the winding assembly 10, the first synchronizing pulley 21, the synchronizing element 24, the synchronizing belt 22, and the slider 23 move synchronously. At this time, the assembly consisting of the left end of the winding assembly 10, the left-side first synchronizing pulley 21, the left-side synchronizing belt 22, and the left-side synchronizing element 24 can be called the left-side transmission assembly. Similarly, the assembly consisting of the right end of the winding assembly 10, the right-side first synchronizing pulley 21, the right-side synchronizing belt 22, and the right-side synchronizing element 24 can be called the right-side transmission assembly.

[0069] The sunshade assembly in related technologies includes components such as guide rails, front crossbeams, rear crossbeams, motors, rollers, and mounting brackets. The assembly of the sunshade assembly generally involves first bolting the front crossbeam to the guide rails, then inserting the mounting brackets into the corresponding slots on the guide rails. Next, the rear crossbeam is pre-assembled with the mounting brackets and secured with bolts. Finally, the iron core end of the roller is inserted into the square hole of the left mounting bracket, and the plastic bead end is installed into the round hole of the right mounting bracket. After confirming that the roller is installed, the pull rod and slider fixed to one end of the curtain are then fastened and secured. The assembly process of the sunshade assembly is relatively complex.

[0070] Furthermore, during the movement of the slider, the motor controls the slider's sliding within the guide rail by traction steel wires. When the sliders on both sides are out of sync, i.e., the sliders cannot align, the straightness of the reel will be affected, causing the curtain to not move in a straight line. Since the sliders are in the guide rail and the reel is fixed to the rear crossbeam, if it is necessary to adjust the relative position of the sliders on both sides, the only way is to adjust the relative position of the sliders on both sides at the motor location by adjusting the length of the steel wires on both sides. Moreover, in addition to disassembling the motor, the steel armor plates, bolts, and other components that cooperate with the motor, such as the motor, the open timing belt, and the frame, are also required for adjustment, making the adjustment quite difficult.

[0071] In this embodiment, when the synchronizing element 24 is installed at both ends of the winding assembly 10, the first synchronizing wheels 21 at both ends of the winding assembly 10 are connected to the winding assembly 10. That is, as shown in Figure 1, the synchronizing element 24 on the left connects the first synchronizing wheel 21 on the left to the winding assembly 10, and the synchronizing element 24 on the right connects the first synchronizing wheel 21 on the right to the winding assembly 10. In other words, the first synchronizing wheels 21 on both sides of the winding assembly 10 are connected to the winding assembly 10. At this time, the first synchronizing wheel 21 on the left, the winding assembly 10, and the first synchronizing wheel 21 on the right are interconnected, and the three rotate synchronously.

[0072] When the first synchronous pulley 21 on the right rotates at a certain angle, the first synchronous pulley 21 on the left rotates at the same angle, causing the two synchronous belts 22 connected to the first synchronous pulley 21 to move the same distance. This, in turn, causes the two sliders 23 fixed to the synchronous belts 22 to move the same distance. In other words, the two sliders 23 move synchronously at this time, meaning that the left transmission component moves synchronously with the right transmission component. When the slider 23 moves away from the winding assembly 10, it pulls the curtain 20 to unfold. When the slider 23 moves towards the winding assembly 10, it pulls the curtain 20 towards the winding assembly 10 and rewinds it.

[0073] When the sliders 23 on both sides are out of sync, i.e., the sliders 23 on both sides are not aligned, this embodiment can be adjusted by the following method: specifically, the synchronizing member 24 on one or both sides of the winding assembly 10 is removed. As shown in Figure 1, for example, the synchronizing member 24 on the right side can be removed. At this time, the first synchronizing wheel 21 on the left side is connected to the winding assembly 10, and the two rotate synchronously. The first synchronizing wheel 21 on the right side is not connected to the winding assembly 10, that is, the first synchronizing wheel 21 on the right side can rotate relative to the winding assembly 10. In other words, the first synchronizing wheel 21 on the right side can rotate relative to the first synchronizing wheel 21 on the left side. Since the timing belt 22 is connected to the first timing wheel 21, the two timing belts 22 on both sides can also move relative to each other.

[0074] Based on this, slider 23 is fixed to synchronous belt 22, meaning that slider 23 on the right can also slide relative to slider 23 on the left in the extension direction of synchronous belt 22. In other words, the left and right transmission components move relative to each other. That is, after disassembling the synchronizing element 24, the relative position of the two sliders 23 can be adjusted by causing the two first synchronous pulleys 21 to rotate relative to each other. Furthermore, after adjusting the relative position of the two sliders 23 to realign them, reinstalling the synchronizing element 24 on the right will allow the sliders 23 on both sides to move synchronously again. The process of adjusting the relative position of the sliders 23 is convenient and quick.

[0075] Meanwhile, the synchronous belt 22, synchronous component 24, and first synchronous pulley 21 enable the winding assembly 10 to move synchronously with the sliders 23 on both sides, improving the synchronization between the winding assembly 10 and the two sliders 23. This allows the entire sunshade assembly 1 to be effectively driven, reducing the risk of the left and right sliders 23 becoming out of sync. Furthermore, the structure of the sunshade assembly 1 is relatively simple, improving the ease of installation of the winding assembly 10.

[0076] Optionally, as shown in Figure 1, when adjusting the relative position of the slider 23 in this embodiment, only the right-side synchronizing member 24 can be disassembled, or only the left-side synchronizing member 24 can be disassembled, or both synchronizing members 24 on both sides can be disassembled simultaneously. Further optionally, in this embodiment, after disassembling the synchronizing member 24, when adjusting the relative position of the slider 23, only one side of the first synchronizing wheel 21 can be rotated, or both sides of the first synchronizing wheels 21 can be rotated simultaneously to resynchronize the position of the slider 23.

[0077] In summary, this embodiment, through the aforementioned synchronization element 24, enables the two first synchronization wheels 21 to rotate synchronously. Furthermore, after removing the synchronization element 24, the first synchronization wheels 21 can also rotate independently, allowing the two first synchronization wheels 21 to rotate relative to each other. This, in turn, allows the two sliders 23 connected to the two first synchronization wheels 21 via the synchronization belt 22 to move synchronously or relative to each other. When the two sliders 23 move synchronously, they can stably pull the curtain 20 to open and close. When the two sliders 23 are not aligned, this embodiment can adjust the relative position of the two sliders 23 by removing the synchronization element 24, causing the two first synchronization wheels 21 to rotate relative to each other, thereby realigning the two sliders 23. This adjustment method is convenient and quick.

[0078] Please refer again to Figures 1-3. In this embodiment, the winding assembly 10 has two first connecting parts 11 at opposite ends, each first synchronizing wheel 21 has a second connecting part 210, and each synchronizing member 24 has a third connecting part 240. The third connecting part 240 can detachably connect the first connecting part 11 and the second connecting part 210.

[0079] As can be seen from the above, the synchronizing element 24 is detachably connected to the first synchronizing pulley 21 and the winding assembly 10. Based on this, in this embodiment, two first connecting portions 11 are respectively provided at both ends of the winding assembly 10, each first synchronizing pulley 21 is provided with a second connecting portion 210, and each synchronizing element 24 is provided with a third connecting portion 240. The first connecting portions 11 and the second connecting portions 210 are detachably connected through the third connecting portion 240, thereby realizing the detachable connection between the synchronizing element 24 and the first synchronizing pulley 21 and the winding assembly 10.

[0080] As shown in Figure 1, when the right-side synchronizing member 24 is installed, its third connecting portion 240 connects the first connecting portion 11 at the right end of the take-up assembly 10 to the second connecting portion 210 of the right-side first synchronizing wheel 21, thus connecting the right-side first synchronizing wheel 21 to the take-up assembly 10. This allows the synchronizing member 24 to rotate synchronously with the first synchronizing wheel 21 and the take-up assembly 10 when the synchronizing member 24 rotates. In other words, the right-side first synchronizing wheel 21 is radially fixed to the take-up assembly 10, meaning it rotates synchronously with the take-up assembly 10. Similarly, the left-side first synchronizing wheel 21 can also rotate synchronously with the take-up assembly 10. When the synchronizing member 24 is disassembled, its third connecting portion 240 disconnects the first connecting portion 11 from the second connecting portion 210, allowing the first synchronizing wheel 21 to rotate relative to the take-up assembly 10.

[0081] Optionally, the detachable structure of the first connecting part 11, the second connecting part 210, and the third connecting part 240 can be a connection structure of a slot and a locking block 241. Alternatively, the first synchronous pulley 21 can be sleeved on the take-up assembly 10, with the first connecting part 11 and the second connecting part 210 being holes, and the third connecting part 240 being a pin. The third connecting part 240 can pass through both the first connecting part 11 and the second connecting part 210 simultaneously, thereby connecting the first connecting part 11 and the second connecting part 210. That is, the third connecting part 240 is a short rod, and by passing the short rod through the holes of both the first connecting part 11 and the second connecting part 210 simultaneously, the first synchronous pulley 21 is fixed to the take-up assembly 10. When the short rod is pulled out of the hole, the first synchronous pulley 21 is released from the take-up assembly 10, that is, the first synchronous pulley 21 and the take-up assembly 10 can rotate relative to each other.

[0082] This embodiment provides a first connecting portion 11 at both ends of the winding assembly 10, a second connecting portion 210 on the first synchronous pulley 21, and the first connecting portion 11 and the second connecting portion 210 are detachably connected to each other by the third connecting portion 240 of the synchronizing member 24, making the connection between the winding assembly 10 and the first synchronous pulley 21 more stable and the installation and disassembly quicker.

[0083] Please refer again to Figures 1-3. In this embodiment, the two first synchronous pulleys 21 are sleeved on the opposite ends of the winding assembly 10. The first connecting part 11 includes a first slot 110, the second connecting part 210 includes a second slot 211, and the third connecting part 240 includes a locking block 241. The locking block 241 is inserted into and removed from the first slot 110 and the second slot 211.

[0084] When the first synchronizing pulley 21 and the take-up assembly 10 are detachably connected via a locking block 241 and a locking slot, the first connecting part 11 can have a first locking slot 110, the second connecting part 210 can have a second locking slot 211, and the third connecting part 240 can have a locking block 241. The locking block 241 can be inserted into the first locking slot 110 and the second locking slot 211 simultaneously to achieve synchronous rotation of the first synchronizing pulley 21 and the take-up assembly 10. In other words, the locking block 241 can be understood as a pin, which simultaneously engages the first locking slot 110 and the second locking slot 211 to make the first synchronizing pulley 21 and the take-up assembly 10 rotate synchronously. When the locking block 241 is pulled out from the first locking slot 110 and the second locking slot 211, the first synchronizing pulley 21 and the take-up assembly 10 can rotate relative to each other. In addition, in this embodiment, the two first synchronous rollers 21 can be fitted onto opposite ends of the winding assembly 10, as shown in Figure 1, with one first synchronous roller 21 fitted onto the right end of the winding assembly 10 and the other first synchronous roller 21 fitted onto the left end of the winding assembly 10. This fitted arrangement makes it easier for the first slot 110 of the winding assembly 10 and the second slot 211 of the first synchronous roller 21 to align, thereby making the insertion of the locking block 241 more convenient.

[0085] Specifically, the first slots 110 are respectively opened at both ends of the take-up assembly 10. The shaft of the first synchronous wheel 21 can also be hollow, so that the first synchronous wheel 21 can be sleeved on both ends of the take-up assembly 10. The second slot 211 is opened at the end of the first synchronous wheel 21 facing away from the take-up assembly 10. When the first synchronous wheel 21 is sleeved on the take-up assembly 10, the first slot 110 can partially overlap with the second slot 211. The synchronizing member 24 can be in the form of a bushing, and the side of the synchronizing member 24 has a locking block 241 protruding from the surface of the synchronizing member 24. When the synchronizing member 24 is installed at both ends of the take-up assembly 10, the locking block 241 of the synchronizing member 24 can be inserted into the first slot 110 and the second slot 211 at the same time, thereby connecting the first synchronous wheel 21 and the take-up assembly 10, so that the first synchronous wheel 21 and the take-up assembly 10 can rotate synchronously.

[0086] This embodiment provides a first slot 110 in the winding assembly 10, a second slot 211 in the first synchronizing pulley 21, and a locking block 241 in the synchronizing member 24. This makes the installation and removal of the synchronizing member 24 simpler and the installation more stable.

[0087] Of course, in other embodiments, the slots can also be provided in the synchronizing member 24, and the winding assembly 10 and the first synchronizing wheel 21 can each have a first locking block 241 and a second locking block 241. When the synchronizing member 24 is fixed to both ends of the winding assembly 10, the first locking block 241 and the second locking block 241 are simultaneously inserted into the slots of the synchronizing member 24, thereby realizing the synchronous rotation of the winding assembly 10 and the first synchronizing wheel 21.

[0088] Please refer again to Figures 1-3. In this embodiment, the winding assembly 10 is provided with a through hole 16 in the axial direction. The inner wall of the winding assembly 10 and the outer wall of the synchronizing member 24 are connected by a third slot 15 and a buckle 242. The third slot 15 is provided on one of the inner wall of the winding assembly 10 and the outer wall of the synchronizing member 24, and the buckle 242 is provided on the other of the inner wall of the winding assembly 10 and the outer wall of the synchronizing member 24.

[0089] As can be seen from the above, the synchronizing element 24 is located at both ends of the winding assembly 10. In this embodiment, the winding assembly 10 can have a through hole 16 in its axial direction, that is, the winding assembly 10 has a through hole 16 in its length direction; in other words, the winding assembly 10 is a hollow tube. Furthermore, the synchronizing element 24 can be inserted into the winding assembly 10 and fixed to both ends of the winding assembly 10 by means of the third slot 15 and the buckle 242.

[0090] In one embodiment, the inner wall of the take-up assembly 10 has a third slot 15, and the surface of the synchronizing member 24 has a buckle 242. When the synchronizing member 24 is installed at both ends of the take-up assembly 10, the synchronizing member 24 can be inserted into the take-up assembly 10 and engaged with the inner wall of the take-up assembly 10 by the buckle 242, thereby preventing the synchronizing member 24 from falling off. In another embodiment, the inner wall of the take-up assembly 10 may also have a buckle 242, and the surface of the synchronizing member 24 may have a third slot 15. When the synchronizing member 24 is inserted into the take-up assembly 10, the buckle 242 can engage with the third slot 15, so that the synchronizing member 24 is engaged with both ends of the take-up assembly 10, thereby preventing the synchronizing member 24 from falling off.

[0091] Please refer to Figure 8, which is a partially exploded view of the sunshade assembly shown in Figure 1 in another embodiment of this application. In this embodiment, the sunshade assembly 1 further includes a drive member 25, which is detachably connected to a synchronization member 24, and the drive member 25 can drive the synchronization member 24 to rotate, thereby driving the winding assembly 10 and the first synchronization wheel 21 to rotate.

[0092] The sunshade assembly 1 may also include a drive unit 25, which is mainly used to provide driving force to drive other components to move. Optionally, the drive unit 25 can be an electric drive unit 25, such as a motor, which drives the components within the sunshade assembly 1 to move. Alternatively, it can be a manual drive unit 25, such as a pull rod 31 or a zipper, which drives the components within the sunshade assembly 1 to move manually.

[0093] Alternatively, when the driving component 25 is a motor, the synchronizing component 24 connected to the motor can also be called a motor bushing, and the synchronizing component 24 on the side away from the motor can also be called a connecting bushing.

[0094] Alternatively, when the driving component 25 is a motor, the motor can be L-shaped, and the motor can also be called an L-shaped motor. By setting the motor to L-shape, it is easier to fix the motor.

[0095] In this embodiment, the drive member 25 is disposed at one end of the take-up assembly 10, and the drive member 25 is connected to the synchronization member 24 on the same side as the drive member 25. For example, the drive member 25 can be disposed at the right end of the take-up assembly 10, and the drive member 25 is connected to the synchronization member 24 on the right side. When the drive member 25 drives the synchronization member 24 on the right side to rotate, the synchronization member 24 on the right side drives the first synchronization wheel 21 on the right side to rotate synchronously with the right end of the spool 12. The left end of the spool 12 also rotates synchronously with the right end of the spool 12, thereby causing the left end of the spool 12 to drive the synchronization member 24 on the left side to rotate synchronously. The synchronization member 24 on the left side drives the first synchronization wheel 21 on the left side to rotate synchronously, thereby causing the first synchronization wheels 21 on both the left and right sides to rotate synchronously.

[0096] When the first synchronous pulleys 21 on both the left and right sides rotate synchronously, they drive the synchronous belts 22 on both sides to move synchronously, thereby causing the two sliders 23 on the left and right sides to move synchronously, which in turn causes the sliders 23 to pull the curtain 20 to open and close smoothly. In other words, the driving member 25 can indirectly drive the opening and closing of the curtain 20 by driving the rotation of the synchronous member 24 connected to the driving member 25. In this embodiment, the driving member 25 drives the rotation of the synchronous member 24, thereby indirectly driving the movement of the curtain 20, making the movement of the curtain 20 stable and uniform in the opening and closing process.

[0097] Of course, in other embodiments, the drive member 25 may not be connected to the synchronization member 24, but to other components. For example, the drive member 25 may be connected to the winding assembly 10, and the rotation of the curtain 20 may be indirectly driven by driving the rotation of the winding assembly 10.

[0098] When the sliders 23 on the left and right sides are not aligned, and the drive component 25 is connected to the synchronizer 24, there are several ways to adjust the sliders 23. Specifically, when choosing to remove the synchronizer 24 on one side of the drive component 25 to adjust the relative position of the sliders 23 on both sides, it is necessary to first remove the drive component 25, and then remove the synchronizer 24 on the same side as the drive component 25. Alternatively, one can choose to remove the synchronizer 24 on the side opposite to the drive component 25. In this case, it is no longer necessary to remove the drive component 25 to remove the synchronizer 24, thereby achieving the adjustment of the relative position of the sliders 23. The adjustment steps are simpler.

[0099] Please refer to Figures 9 and 10. Figure 9 is a cross-sectional schematic diagram of the winding assembly and the synchronizing element in one embodiment of this application. Figure 10 is a partially enlarged view of the winding assembly and the synchronizing element shown in Figure 9 in action. In this embodiment, the winding assembly 10 includes a spool 12 and a support member 13. The support member 13 is inserted into the spool 12. Each synchronizing element 24 is detachably connected to the support member 13 and the first synchronizing pulley 21 located on the same side as the synchronizing element 24.

[0100] In this embodiment, the winding assembly 10 includes a roller 12 and a support member 13. One end of the curtain fabric 20 is fixed to the roller 12, and the curtain fabric 20 is wound around the roller 12. The support member 13 is mainly used to support the roller 12 and has a rod-shaped structure; therefore, the support member 13 can also be called a support rod. The support member 13 is disposed inside the roller 12, meaning the roller 12 has a hollow structure. The internal space of the roller 12 can accommodate the support member 13, and the support member 13 can rotate synchronously with the roller 12 under the connection of other components. As can be seen from the above, the synchronizing member 24 is detachably connected to the winding assembly 10 and the first synchronizing wheel 21. In this embodiment, the synchronizing member 24 can be detachably connected to the support member 13 and the first synchronizing wheel 21 located on the same side as the synchronizing member 24. By setting the roller 12 and the support member 13, the function of the winding assembly 10 in winding the curtain fabric 20 and the function of rotating synchronously with the first synchronizing wheel 21 are separated, which facilitates the installation and disassembly of the winding assembly 10.

[0101] Optionally, the support member 13 is a long rod that runs through the entire scroll 12. Of course, in other embodiments, the support member 13 can also be two short rods, which are respectively inserted at both ends of the scroll 12.

[0102] Please refer again to Figures 9-10. In this embodiment, the winding assembly 10 further includes a fixing member 14, which is disposed inside the reel 12 and is fixed between the support member 13 and the reel 12.

[0103] As described above, the support member 13 is inserted inside the reel 12. Furthermore, in this embodiment, the support member 13 can also be inserted inside the reel 12 via a fixing member 14. The fixing member 14 is mainly used to fix the reel 12 and the support member 13. In this embodiment, the fixing member 14 can be fixed between the support member 13 and the reel 12; that is, the fixing member 14 is sleeved on the support member 13, and the reel 12 is sleeved on the fixing member 14. The fixing member 14 allows the reel 12 and the support member 13 to rotate in the same direction, while also reducing the assembly difficulty of the winding assembly 10.

[0104] In this embodiment, the fixing member 14 is elastic. When the winding assembly 10 rotates, the rotation angle of the roller 12 is different from that of the support member 13, so that the fixing member 14 is in a deformed state, thereby enabling the roller 12 to rotate relative to the support member 13, and thus making the moving distance of the curtain 20 the same as the moving distance of the slider 23.

[0105] As can be seen from the above, the fixing member 14 is fixedly connected to the support member 13 and the roller 12. Based on this, this embodiment can make the fixing member 14 elastic, that is, the fixing member 14 can elastically connect the roller 12 and the support member 13. Optionally, the fixing member 14 includes, but is not limited to, elastic components such as coil springs and torsion springs. Since the synchronous belt 22 is connected to the first synchronous pulley 21, when the first synchronous pulley 21 rotates one revolution, the distance the synchronous belt 22 moves is the circumference of the first synchronous pulley 21. And the slider 23 is fixed to the synchronous belt 22, that is, when the first synchronous pulley 21 rotates one revolution, the distance the slider 23 moves is the same as the distance the synchronous belt 22 moves, both being the circumference of the first synchronous pulley 21. At the same time, the slider 23 is fixed to both sides of the curtain 20, so the curtain 20 and the slider 23 need to move the same distance to prevent the curtain 20 from being pulled or wrinkled. Therefore, when the distance the slider 23 moves is the circumference of the first synchronous pulley 21, the curtain 20 also needs to move the same distance, that is, the circumference of the first synchronous pulley 21.

[0106] However, the radius of the curtain 20 wound around the roller 12 is different from that of the first synchronous pulley 21, and the radius of the curtain 20 wound around the roller 12 changes continuously as the curtain 20 winds around or unwinds from the roller 12. Therefore, when the movement distance of the curtain 20 is the same as that of the slider 23, which is equal to the circumference of the first synchronous pulley 21, the roller 12 needs to rotate at an angle greater than or less than one revolution. In other words, when the curtain 20 and the slider 23 move the same distance, the roller 12 and the first synchronous pulley 21 need to rotate at different angles to compensate for the difference in travel distance between the curtain 20 and the slider 23 when the roller 12 and the first synchronous pulley 21 rotate. Furthermore, since the support member 13 is fixed to the first synchronous pulley 21, i.e., the support member 13 rotates synchronously with the first synchronous pulley 21, the roller 12 will rotate relative to the support member 13.

[0107] This embodiment allows the fixing member 14 to be elastic, meaning that the fixing member 14 elastically connects the roller 12 and the support member 13. When the roller 12 and the support member 13 rotate, the fixing member 14 can deform, allowing the roller 12 and the support member 13 to rotate relative to each other. This compensates for the difference in travel distance between the curtain 20 and the slider 23, preventing the curtain 20 from wrinkling or being pulled. Simultaneously, the elasticity of the fixing member 14 ensures that the roller 12 and the support member 13 remain connected during relative rotation, preventing disconnection; that is, the support member 13 can still drive the roller 12 to move.

[0108] Please refer to Figure 11, which is an exploded view of the timing belt, the first timing pulley, and the second timing pulley in one embodiment of this application. In this embodiment, the timing belt 22 is provided with a first engagement portion 221, and the first timing pulley 21 is provided with a second engagement portion 212. The first engagement portion 221 and the second engagement portion 212 cooperate with each other to connect the timing belt 22 and the first timing pulley 21.

[0109] As can be seen from the above, the synchronous belt 22 is connected to the first synchronous pulley 21. Based on this, this embodiment allows the synchronous belt 22 to mesh with the first synchronous pulley 21. Specifically, a first meshing part 221 can be placed on the side of the synchronous belt 22 that connects to the first synchronous pulley 21, and a second meshing part 212 can be provided on the outer surface of the first synchronous pulley 21. That is, the first meshing part 221 of the synchronous belt 22 and the second meshing part 212 of the first synchronous pulley 21 cooperate with each other to make the synchronous belt 22 mesh with the first synchronous pulley 21, thereby making the synchronous belt 22 and the first synchronous pulley 21 move synchronously.

[0110] In one embodiment, the first engaging portion 221 is a serrated protrusion, and the second engaging portion 212 is a serrated groove. These two portions can cooperate to engage the synchronous belt 22 with the first synchronous pulley 21. In another embodiment, the first engaging portion 221 can also be a serrated groove, in which case the corresponding second engaging portion 212 is a serrated protrusion. The first engaging portion 221 and the second engaging portion 212 engage to connect the synchronous belt 22 with the first synchronous pulley 21.

[0111] By setting the first meshing part 221 and the second meshing part 212, the synchronous belt 22 and the first synchronous pulley 21 are connected by meshing, making the connection more secure and reducing the possibility of the synchronous belt 22 and the first synchronous pulley 21 sliding, which would cause the sliders 23 on both sides to be misaligned.

[0112] Please refer to Figures 12-15. Figure 12 is a partially exploded view of the sunshade assembly shown in Figure 1 in another embodiment of this application. Figure 13 is a partially enlarged view of the sunshade assembly shown in Figure 12. Figure 14 is a partially enlarged view of the sunshade assembly shown in Figure 13. Figure 15 is a split view of the slider and timing belt in one embodiment of this application. In this embodiment, the slider 23 has a fixing groove 232 on the side opposite to the other end of the curtain 20, and part of the timing belt 22 is fixed in the fixing groove 232.

[0113] As described above, slider 23 is fixed to synchronous belt 22. Based on this, in this embodiment, a fixing groove 232 can be formed on one side of slider 23. The fixing groove 232 is a recess formed on the surface of slider 23, mainly used to cooperate with synchronous belt 22. A portion of synchronous belt 22 is disposed within the fixing groove 232, meaning that synchronous belt 22 passes through and is fixed within the fixing groove 232. Optionally, synchronous belt 22 and slider 23 can be fixed by meshing, screw connection, adhesive bonding, etc. The specific connection method will be described in detail later. Fixing slider 23 to synchronous belt 22 via fixing groove 232 simplifies the fixing of slider 23.

[0114] Based on this, in this embodiment, the fixing groove 232 can also be formed on the side of the slider 23 away from the other end of the curtain 20, that is, as shown in FIG14, the fixing groove 232 is formed on the outside of the slider 23. By forming the fixing groove 232 on the outside of the slider 23, the timing belt 22 is not easy to detach from the slider 23, and the installation and removal of the slider 23 are also convenient.

[0115] Please refer again to Figures 14-15. In this embodiment, the synchronous belt 22 is provided with a first engagement part 221, and the groove wall of the fixing groove 232 is provided with a third engagement part 233. The first engagement part 221 and the third engagement part 233 cooperate with each other to fix the slider 23 to the synchronous belt 22.

[0116] As can be seen from the above, the slider 23 is provided with a fixing groove 232, and the timing belt 22 is fixed in the fixing groove 232, thereby enabling the slider 23 and the timing belt 22 to move synchronously. Based on this, this embodiment can make the fixing groove 232 engage with the timing belt 22, thereby fixing the timing belt 22 in the fixing groove 232. Specifically, as shown in FIG14, a first engaging part 221 can be provided on the inner side of the timing belt 22, and a third engaging part 233 can be provided on the upper groove wall of the fixing groove 232. That is, the first engaging part 221 of the timing belt 22 and the third engaging part 233 of the fixing groove 232 cooperate with each other to fix the timing belt 22 in the fixing groove 232, thereby enabling the timing belt 22 and the slider 23 to move synchronously.

[0117] In one embodiment, the first engaging portion 221 is a serrated protrusion, and the third engaging portion 233 is a serrated groove. The two can cooperate with each other to engage the synchronous belt 22 and the slider 23. In another embodiment, the first engaging portion 221 can also be a serrated groove, and correspondingly, the third engaging portion 233 is a serrated protrusion. The first engaging portion 221 and the third engaging portion 233 engage to fix the synchronous belt 22 and the slider 23.

[0118] By setting the first meshing part 221 and the third meshing part 233, the synchronous belt 22 and the slider 23 are meshed and connected, which is more secure and reduces the possibility of the synchronous belt 22 and the slider 23 sliding, which may cause the sliders 23 on both sides to be misaligned.

[0119] Please refer again to Figures 13-14. In this embodiment, the slider 23 includes a body 231 and a cover plate 234. The body 231 is provided with the fixing groove 232. The cover plate 234 is detachably connected to the body 231 and can cover the fixing groove 232.

[0120] The body 231 is the part that mates with the timing belt 22, and the aforementioned fixing groove 232 is formed in the body 231. The cover plate 234 is a component that mates with the body 231. The cover plate 234 is detachably connected to the body 231, that is, the cover plate 234 can be installed on the body 231, or the cover plate 234 can be separated from the body 231.

[0121] Meanwhile, when the cover plate 234 is installed on the body 231, it can cover the fixing groove 232. That is, when it is necessary to fix the slider 23 to the timing belt 22, the cover plate 234 can be removed from the body 231, exposing the fixing groove 232, and the timing belt 22 can be placed within it. After the timing belt 22 is placed in the fixing groove 232, the cover plate 234 can be reinstalled on the body 231. At this point, the cover plate 234 covers the fixing groove 232, preventing the timing belt 22 from detaching from it, thus increasing the stability of the connection between the slider 23 and the timing belt 22. In this embodiment, the cover plate 234 ensures that the timing belt 22 is stably placed within the fixing groove 232, thereby making the connection between the slider 23 and the timing belt 22 more secure.

[0122] Please refer to Figures 1 and 16 together. Figure 16 is a partial three-dimensional structural schematic diagram of the sunshade assembly shown in Figure 1. In this embodiment, the sunshade assembly 1 further includes a first support beam and two first fixing seats 26. The two first fixing seats 26 are fixed to the opposite ends of the first support beam. The retractable assembly 10 is disposed between the two first fixing seats 26, and the opposite ends of the retractable assembly 10 pass through the two first fixing seats 26.

[0123] The first support beam is mainly used to install various components in the sunshade assembly 1. The first support beam can be located at one end of the sunshade assembly 1. For example, when the sunshade assembly 1 is installed on the vehicle body 4, the first support beam is located at the end of the sunshade assembly 1 furthest from the front of the vehicle; therefore, the first support beam can also be called a rear crossbeam. Optionally, the first support beam can be arranged parallel to the retractable assembly 10. The first fixing seat 26 is also used to install various components in the sunshade assembly 1. The first fixing seat 26 is fixed to both ends of the first support beam, that is, one first fixing seat 26 is fixed to one end of the first support beam, and the other first fixing seat 26 is fixed to the other end of the first support beam. The two first fixing seats 26 are arranged in a U-shape with the first support beam. The two first fixing seats 26 are used together to install the retractable assembly 10.

[0124] In this embodiment, two first fixing seats 26 are respectively disposed at both ends of the winding assembly 10, that is, one first fixing seat 26 is disposed at one end of the winding assembly 10, and the other first fixing seat 26 is disposed at the other end of the winding assembly 10. The two first fixing seats 26 pass through the opposite ends of the winding assembly 10. In other words, the first fixing seats 26 have holes, through which the winding assembly 10 can pass and be confined between the two first fixing seats 26, and the winding assembly 10 can rotate relative to the first fixing seats 26. The first support beam can connect the two fixing seats, thereby limiting the distance between the two fixing seats, and thus preventing the winding assembly 10 from detaching from the fixing seats.

[0125] In this embodiment, by setting the first fixing seat 26 on the first support beam, the winding assembly 10 is limited to the two first fixing seats 26, preventing the winding assembly 10 from shaking in the sunshade assembly 1 and thus affecting the opening and closing of the curtain 20.

[0126] Furthermore, when the winding assembly 10 is installed between the two first fixed seats 26, both ends of the winding assembly 10 extend out of the fixed seats, and the outer portions of the two first synchronizing pulleys 21 also extend out of the fixed seats. The synchronizing member 24 can be installed or removed from the outside of the first fixed seats 26 from the winding assembly 10 and the first synchronizing pulleys 21. That is, when the winding assembly 10 is installed between the fixed seats, the synchronizing member 24 can be directly installed and removed without first removing the winding assembly 10 and then removing the synchronizing member 24.

[0127] Please refer to Figures 1, 16, and 17. Figure 17 is a partial three-dimensional structural schematic diagram of the sunshade assembly shown in Figure 16. In this embodiment, the sunshade assembly 1 further includes two guide rails 27, which are disposed at opposite ends of the retractable assembly 10, and each guide rail 27 is angled relative to the retractable assembly 10. Each guide rail 27 is fixed to a first fixing seat 26, and the guide rail 27 is provided with a sliding groove 270, within which the slider 23 can slide.

[0128] The guide rail 27 is mainly used to cooperate with the slider 23, and also serves as the skeleton structure of the sunshade assembly. Two guide rails 27 are respectively located at opposite ends of the retractable assembly 10, that is, as shown in Figure 1, one guide rail 27 is located at the left end of the retractable assembly 10, and the other guide rail 27 is located at the right end of the retractable assembly 10. Each guide rail 27 is angled to the retractable assembly 10, that is, there is an included angle between the retractable assembly 10 and the guide rail 27. Optionally, the included angle between both guide rails 27 and the retractable assembly 10 is 90°, that is, both guide rails 27 are perpendicular to the retractable assembly 10, and the two guide rails 27 and the retractable assembly 10 are arranged in a U-shape. Of course, in other embodiments, the included angle between the guide rail 27 and the retractable assembly 10 can also be an obtuse angle or an acute angle; this embodiment is only illustrated using a right angle.

[0129] Each guide rail 27 is connected to a first fixing seat 26, as shown in Figure 1. One guide rail 27 is connected to the first fixing seat 26 on the left, and the other guide rail 27 is connected to the first fixing seat 26 on the right. At the same time, the first fixing seats 26 are also fixed to both ends of the guide rail 27. That is, the two first fixing seats 26, the two guide rails 27, and the roll-up assembly 10 are arranged in a U-shape, making the overall structure of the sunshade assembly 1 more stable.

[0130] In addition, the guide rail 27 is provided with a groove 270, and the slider 23 can slide within the groove 270. That is, the slider 23 can slide within the guide rail 27 along the extension direction of the groove 270. This makes the sliding path of the slider 23 determined, that is, the groove 270 plays the role of guiding the slider 23, and makes the sliding smoother when moving synchronously with the timing belt 22.

[0131] Specifically, the groove 270 is formed on the inner side of each guide rail 27, as shown in Figure 17. The groove 270 of the left guide rail 27 is formed on the right side of the guide rail 27, and the groove 270 of the right guide rail 27 is formed on the left side of the guide rail 27. Furthermore, the groove 270 penetrates through the guide rail 27, meaning that in addition to having an opening on the inner side of the guide rail 27, the groove 270 also has openings on both sides of the guide rail 27. Of course, in other embodiments, the groove 270 can also be formed on other surfaces of the guide rail 27, for example, as shown in Figure 17, the groove 270 can be formed on the upper surface of the guide rail 27.

[0132] Please refer again to Figures 16-17. In this embodiment, the first fixed base 26 is provided with a limiting member 260. The limiting member 260 is provided on one side of the slide groove 270 in the extension direction of the slide groove 270, and the slider 23 can abut against the limiting member 260.

[0133] As can be seen from the above, slider 23 can slide within the groove 270. Based on this, in this embodiment, a limiting member 260 can be provided at a position on the first fixed base 26 along the extending direction of the groove 270. The limiting member 260 is mainly used to cooperate with slider 23 to limit slider 23; therefore, the limiting member 260 can also be called the slider 23 stop point. The limiting member 260 is located on one side of the groove 270 along its extending direction. The extending direction of the groove 270 is the length direction of the guide rail 27 and the sliding direction of slider 23, i.e., the X direction as shown in Figure 17. When slider 23 slides along the extending direction of the groove 270, i.e., the X direction, slider 23 can abut against the limiting member 260. That is, the limiting member 260 can restrict the position of slider 23 in the X direction, thereby preventing slider 23 from disengaging from the guide rail. The position where slider 23 abuts against the limiting member 260 at this time can also be called the initial stop point position. In this embodiment, the limiting member 260 ensures that the slider 23 is stably positioned within the groove 270 and will not detach from the groove 270, thereby improving the sliding stability of the slider 23.

[0134] Please refer again to Figures 16-17. In this embodiment, the limiting member 260 is provided with a first limiting part 261, and the slider 23 is provided with a second limiting part 236. The first limiting part 261 and the second limiting part 236 cooperate with each other to limit the slider 23 to the limiting member 260.

[0135] As can be seen from the above, when the slider 23 slides along the X direction, it can abut against the limiting member 260 to prevent the slider 23 from derailing. Based on this, this embodiment further adds a first limiting part 261 to the limiting member 260 and a second limiting part 236 to the slider 23. These two parts can cooperate to limit the slider 23. The first limiting part 261 includes one of a limiting protrusion and a limiting groove, and the second limiting part 236 includes the other of a limiting protrusion and a limiting groove. For example, if the first limiting part 261 is a groove, then the corresponding second limiting part 236 can be a protrusion. When the slider 23 abuts against the limiting member 260, the second limiting part 236 can be inserted into the first limiting part 261, thereby limiting the position of the slider 23 in the two slider 23 arrangement directions, i.e., the position in the Y direction as shown in Figure 17, and the position in the thickness direction of the slider 23, i.e., the position in the Z direction as shown in Figure 17. By restricting the position of slider 23 in the XYZ directions, the limiting member 260 can limit slider 23 from multiple dimensions, thereby reducing the risk of slider 23 derailing.

[0136] Of course, in other embodiments, the first limiting part 261 can be a protrusion, and the corresponding second limiting part 236 can be a groove. That is, when the slider 23 abuts against the limiting member 260, the first limiting part 261 can be inserted into the second limiting part 236 to limit the position of the slider 23 in the Y and Z directions. By providing the first limiting part 261 and the second limiting part 236, this embodiment makes the limiting effect of the slider 23 when it abuts against the limiting member 260 better, reducing the probability of the slider 23 derailing.

[0137] Please refer again to Figures 16-17. In this embodiment, the distance between the limiting member 260 and the guide rail 27 is greater than the length of the slider 23 along the extension direction of the groove 270.

[0138] As can be seen from the above, the limiting member 260 can limit the position of the slider 23 in the X direction. Based on this, in this embodiment, the distance between the limiting member 260 and the guide rail 27 is greater than the length of the slider 23 in the extension direction of the groove 270. In other words, the limiting member 260 is not just set next to the guide rail 27, but there is a certain gap between it and the guide rail 27, and this gap is greater than the length of the slider 23 in the X direction, so that the process of installing the slider 23 into the groove 270 is more convenient.

[0139] When installing slider 23, it is usually necessary to first fix slider 23 to the opposite sides of the other end of curtain 20, and then place slider 23 into slide groove 270 so that slider 23 can slide within slide groove 270. In this embodiment, by making the distance between limiting member 260 and guide rail 27 greater than the length of slider 23 in the X direction, slider 23 can be directly installed into slide groove 270 through the gap between limiting member 260 and guide rail 27, making the installation of slider 23 simpler and faster.

[0140] Please refer to Figure 17 again. In this embodiment, the slider 23 includes a body 231 and an elastic element 235. The body 231 is fixed on the synchronous belt 22. The elastic element 235 protrudes from one side of the body 231 in the thickness direction. When the slider 23 is disposed in the groove 270, the elastic element 235 abuts against the groove wall of the groove 270 and the slider 23 is interference-fitted with the guide rail 27.

[0141] As can be seen from the above, the slider 23 can slide within the groove 270. Based on this, when the groove 270 is located inside the guide rail 27 as described above, this embodiment can add an elastic element 235 to the body 231. The elastic element 235 is mainly used to cooperate with the groove 270. Optionally, as shown in Figure 17, when there is one elastic element 235, it can be fixed to the upper or lower surface of the body 231; when there are two elastic elements 235, they can be fixed to the upper and lower surfaces of the body 231 simultaneously. This embodiment is only illustrated with an example where there is only one elastic element 235 and it is fixed to the upper surface of the body 231.

[0142] When the slider 23 slides within the groove 270, its relatively thin thickness may cause it to wobble in the Z-direction, resulting in unstable sliding. Therefore, this embodiment adds an elastic element 235 to the body 231, increasing the thickness of the slider 23. This allows for an interference fit between the slider 23 and the groove 270, ensuring that both the upper and lower sides of the slider 23 abut against the inner wall of the groove 270 in the Z-direction, as shown in Figure 17. The elastic element 235 can deform to a certain extent, applying a rebound force to the groove wall, ensuring that both sides of the slider 23 stably abut against the inner wall of the groove 270 in the Z-direction. This prevents the slider 23 from shifting in the Z-direction, improving its sliding stability, and preventing it from impacting the groove wall and causing noise.

[0143] Optionally, the elastic element 235 can be an arch bridge shape, with both ends of the arch bridge fixed to the body 231 and the arch direction of the arch bridge facing away from the body 231. By making the elastic element 235 an arch bridge shape, the contact area between the elastic element 235 and the groove wall is smaller when the elastic element 235 abuts against the groove wall, thus reducing the friction between the slider 23 and the groove wall. In addition, the arch bridge-shaped elastic element 235 can be a sheet-like arch bridge shape, thereby allowing the elastic element 235 to have a larger deformation space and better elasticity.

[0144] Please refer to Figures 1 and 16-18, with Figure 18 being a partial enlarged view of the sunshade assembly shown in Figure 1. In this embodiment, the synchronous belt 22 and the slider 23 located on one side of the first synchronous pulley 21 are disposed within the slide groove 270, while the synchronous belt 22 located on the other side of the first synchronous pulley 21 is located outside the slide groove 270. The sunshade assembly 1 also includes a second synchronous pulley 28, which is disposed on the side of the guide rail 27 opposite to the first synchronous pulley 21, and the synchronous belt 22 is also sleeved on the second synchronous pulley 28.

[0145] As can be seen from the above, slider 23 is fixed to synchronous belt 22, slider 23 slides within guide rail 27, and synchronous belt 22 moves synchronously with slider 23. Therefore, synchronous belt 22 also has a certain positional relationship with guide rail 27. In this embodiment, the sunshade assembly 1 also includes a second synchronous pulley 28, which is mainly used to cooperate with synchronous belt 22 and support synchronous belt 22 together with first synchronous pulley 21. Optionally, second synchronous pulley 28 is meshed with synchronous belt 22. There are two second synchronous pulleys 28, which are arranged on the other side of guide rail 27 corresponding to the two first synchronous pulleys 21. In other words, first synchronous pulley 21 and second synchronous pulley 28 are located at opposite ends of guide rail 27. At this time, first synchronous pulley 21 can also be called rear synchronous pulley, and second synchronous pulley 28 can also be called front synchronous pulley. Each synchronous belt 22 is respectively fitted with and connected to one first synchronous pulley 21 and one second synchronous pulley 28. That is to say, synchronous belt 22 is connected to first synchronous pulley 21, second synchronous pulley 28 and slider 23, and the four move synchronously. The arrangement of the first synchronous pulley 21 makes the structure of the left and right transmission components more complete and the transmission effect better.

[0146] Based on this, in this embodiment, the timing belt 22 on one side of the first timing pulley 21 is disposed within the groove 270, while the timing belt 22 on the other side of the first timing pulley 21 is disposed outside the groove 270. That is, as shown in Figure 17, the upper timing belt 22 is disposed outside the groove 270, while the lower timing belt 22, together with the slider 23, is disposed within the groove 270. By disposing of the upper timing belt 22 outside the groove 270 and the lower timing belt 22 within the groove 270, a certain gap is created between the timing belts 22, thereby reducing the difficulty of fitting the timing belt 22 onto the second timing pulley 28. Furthermore, during the sliding process of the slider 23, the upper timing belt 22 will not interfere with the slider 23, improving the stability of the slider 23's sliding.

[0147] Of course, in other embodiments, the timing belts 22 on both sides of the first timing pulley 21 can also be disposed within the groove 270. That is, as shown in Figure 17, both the upper and lower timing belts 22 are disposed within the groove 270. This ensures that the timing belt 22 remains within the relatively enclosed groove 270 during its movement, reducing interference encountered by the timing belt 22 during its movement.

[0148] Optionally, in this embodiment, the sunshade assembly 1 further includes a second fixing seat 29 and a second support beam. The second support beam is mainly used to install various components in the sunshade assembly 1, and the second support beam can be set at one end of the sunshade assembly 1. For example, when the sunshade assembly 1 is installed on the vehicle body 4, the first support beam is set at the end of the sunshade assembly 1 near the front of the vehicle, so the second support beam can also be called a front crossbeam. The second fixing seat 29 is also used to install various components in the sunshade assembly 1. There are two second fixing seats 29, which are respectively fixed to the end of the guide rail 27 away from the retracting assembly 10. In other words, the first fixing seat 26 and the second fixing seat 29 are set at opposite ends of the guide rail 27.

[0149] In addition, the second fixing seat 29 is also used to fix the second synchronous pulley 28, thereby making the movement of the synchronous belt 22 smoother. The second support beam, the first support beam and the two guide rails 27 together form the skeleton structure of the rectangular sunshade assembly 1, making the overall structure of the sunshade assembly 1 more stable.

[0150] In this embodiment, the fixing seat may further include a shaping part 262, which is disposed on the side of the fixing seat near the first synchronous pulley 21. The shaping part 262 is mainly used to shape the lower synchronous belt 22, causing the synchronous belt 22 to gradually bend. As can be seen from the above, the lower synchronous belt 22 and the slider 23 are both disposed within the groove 270. Based on this, in this embodiment, a shaping part 262 can be added to the upper surface of the fixing seat. The shaping part 262 abuts against the synchronous belt 22, causing the synchronous belt 22 to bend. This creates a certain gap between the synchronous belt 22 and the inner wall of the groove 270, thereby reducing the frictional force of the slider 23 during sliding within the groove 270, and thus improving the smoothness of the slider 23's sliding.

[0151] In addition, this application also provides an assembly method for a sunshade assembly 1, the specific assembly method being as follows: First, the roller 12 is fitted onto the support member 13, and the support member 13 is inserted into the roller 12 by means of the fixing member 14. Two first synchronous pulleys 21 are respectively fitted onto both ends of the support member 13. One end of the curtain fabric 20 is fixed and wound around the roller 12, and the other end of the curtain fabric 20 is fixedly connected to the pull rod 31. Then, two sliders 23 are respectively fixed to both ends of the pull rod 31.

[0152] Then, two first synchronous pulleys 21 are pre-installed on the two synchronous belts 22 respectively. Next, two first fixed seats 26 are respectively placed at both ends of the support member 13, with the support member 13 passing through the two first fixed seats 26. The two first fixed seats 26 are then connected by a first support beam. The two first fixed seats 26 are then connected and fixed to two guide rails 27 respectively. The other ends of the two guide rails 27 are respectively fixed to two second fixed seats 29, which are connected and fixed by a second support beam. The slider 23 is then inserted into the guide rail 27 and abuts against the limiting member 260, positioning the slider 23 at the initial stop position.

[0153] After attaching the two synchronous belts 22 to the two second synchronous pulleys 28, the two second synchronous pulleys 28 are fixed to the two second fixed seats 29, respectively. That is, the two synchronous belts 22 are connected to one first synchronous pulley 21 and one second synchronous pulley 28. Rotate the first synchronous pulley 21 until the first engagement part 221 of the synchronous belt 22 is aligned with the second engagement part 212 of the slider 23. Press the synchronous belt 22 into the fixing groove 232 of the slider 23, and install the cover plate 234 to cover the synchronous belt 22.

[0154] Rotate the first synchronizing pulley 21 so that the first slot 110 on one side of the support member 13 coincides with the second slot 211 of the first synchronizing pulley 21. Insert the synchronizing member 24 to connect the support member 13 and the first synchronizing pulley 21. Similarly, the other side is also connected to the support member 13 and the first synchronizing pulley 21 via the synchronizing member 24. Finally, fix the driving member 25 to one side of the support member 13 and connect the driving member 25 to the synchronizing member 24 on the same side.

[0155] The above assembly method simplifies the assembly process of the sunshade assembly 1, reduces the number of steps, and lowers the operating cost.

[0156] Furthermore, based on the above assembly method and the assembled sunshade assembly 1, when the sliders 23 are not aligned, it is only necessary to first disassemble the synchronizing component 24, and then adjust the position of one slider 23 by rotating the first synchronizing wheel 21 to align it with the other slider 23. Finally, the synchronizing component 24 is reinstalled to complete the adjustment. The adjustment method is simple and reduces the difficulty of operation.

[0157] Please refer to Figure 19, which is a schematic diagram of a glass assembly according to one embodiment of this application. This embodiment provides a glass assembly 2, which includes a glass 40 and a sunshade assembly 1 as provided in the above embodiment of this application. The sunshade assembly 1 is fixed to one side of the glass 40.

[0158] The glass assembly 2 includes a glass 40 and a sunshade assembly 1. The glass 40 is located on the top of the vehicle 3, and the sunshade assembly 1 is located below the glass 40. The curtain 20 can then cover or expose the glass 40 under the traction of the slider 23, achieving the purpose of sun shading. Specifically, when the curtain 20 is unfolded, it can cover the glass 40 to block light. When the curtain 20 is retracted, it can expose the glass 40, allowing light to pass through. The glass assembly 2 provided in this embodiment, by adopting the sunshade assembly 1 provided in the above-described embodiment of this application, reduces the difficulty of adjusting the slider 23 when they are out of sync. At the same time, the glass assembly 2 is easy to assemble, with smoother connections between preceding and following processes, reducing operational difficulty and facilitating the disassembly and replacement of the retraction assembly 10. Furthermore, the glass assembly 2 provided in this application improves the stability of the curtain 20 during opening and closing and reduces noise during operation.

[0160] The glass assembly 2 can be installed on the top of the vehicle 3. The glass 40 of the glass assembly 2 is the top glass 40 of the vehicle 3. The rest of the glass assembly 2 is located below the glass 40, i.e. inside the vehicle. The curtain 20 of the sunshade assembly 1 can cover or open the glass 40 by the action of the slider 23.

[0161] The vehicle 3 provided in this embodiment, by adopting the glass assembly 2 as described in the above-described embodiments of this application, reduces the difficulty of adjusting the slider 23, thereby making it easier and faster to analyze and resolve aftermarket quality issues. At the same time, it reduces noise during the operation of the curtain 20, improving the comfort of the vehicle 3.
