Detailed Implementation

[0041] 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.

[0042] Before introducing the technical solution of this application, let's go over the technical issues in related technologies in detail.

[0043] With the development of the automotive industry, competition in the automotive market is becoming increasingly fierce. Many car companies are now focusing on developing large SUVs and MPVs. As vehicle sizes gradually increase, the requirements for the size of roof sunshades are becoming higher and higher. The larger the size, the higher the requirements for the operation of the sunshade assembly. Therefore, large SUVs and MPVs currently prioritize the use of dual sunshade structures, such as a combination of a small front sunshade and a large rear sunshade.

[0044] Currently, the main transmission structure used is a flexible shaft dual-motor system. Its advantages include high transmission efficiency and structural stability, but its disadvantages include: firstly, the dual motors generate significant noise, are heavy, costly, and space-consuming; secondly, achieving synchronized movement of both sunshades with dual motors is quite challenging; and thirdly, the flexible shaft transmission structure results in a large overall weight, high operating resistance, and high noise.

[0045] In view of this, and in order to solve the above problems, this application provides a sunshade assembly, which you may refer to. Figures 1-6 , Figure 1 This is a schematic diagram of the principle of a sunshade assembly according to one embodiment of this application. Figure 2 This is a three-dimensional structural diagram of the sunshade assembly according to one embodiment of this application. Figure 3 for Figure 2 The image shows a front view of the sunshade assembly. Figure 4 for Figure 3 A magnified view of part A in the sunshade assembly shown. Figure 5 for Figure 3 The image shows a magnified view of part B in the sunshade assembly shown. Figure 6 for Figure 3 A magnified view of part C in the sunshade assembly shown.

[0046] The sunshade assembly 1 provided in this embodiment includes a drive unit 10, a first curtain mechanism 20, and a second curtain mechanism 30. The first curtain mechanism 20 includes a first transmission assembly 21, which includes a first synchronizing member 211, a second synchronizing member 212, and a first transmission member 213 sleeved on the first synchronizing member 211 and the second synchronizing member 212. The first synchronizing member 211 is used to fix to the drive unit 10 and to connect to a first winding member 22 on which the first curtain 23 is disposed. The first curtain 23 is also fixed to the first transmission member 213. The second curtain mechanism 30 includes a second transmission assembly 31, which includes a third synchronizing member 311, a fourth synchronizing member 312, and a second transmission member 313 sleeved on the third synchronizing member 311 and the fourth synchronizing member 312. The third synchronizing member 311 is fixed to the second synchronizing member 212 and is coaxially arranged with the second synchronizing member 212. The second winding member 32, which provides the second curtain 33, is connected to the second synchronizing member 212 or the third synchronizing member 311, and the second curtain 33 is also fixed to the second transmission member 313.

[0047] The sunshade assembly 1 provided in this embodiment is mainly applied to the top of various vehicles 5. The movement of the curtain is controlled by the drive component 10, so that the curtain covers or exposes the glass 2 on the top of the vehicle 5. Of course, in other embodiments, the sunshade assembly 1 can also be applied to other glass locations on the vehicle or in other scenarios, such as the windshield, rear window, side window, etc., and can also be installed on residential windows, outdoor awnings, etc. This embodiment only illustrates the application of the sunshade assembly 1 to the sunroof of a vehicle 5.

[0048] The sunshade assembly 1 includes a drive unit 10, a first curtain mechanism 20, and a second curtain mechanism 30. The drive unit 10 is the power source of the sunshade assembly 1, and can drive various movements of the curtain. Optionally, the drive unit 10 can be a manual drive unit, such as a manual joystick, or an electric drive unit, such as a motor. In this embodiment and below, the drive unit 10 is only illustrated as a motor. Specifically, the motor can be a direct-drive motor.

[0049] The first curtain mechanism 20 and the second curtain mechanism 30 form a double sunshade structure, enabling the opening and closing of both curtains. The first curtain mechanism 20 includes two first transmission components 21, a first roll-up component 22, a first curtain 23, and a first sliding component 24. The first roll-up component 22 can be cylindrical and is mainly used to support and load the first curtain 23. The two first transmission components 21 are located on opposite sides of the first roll-up component 22 in the axial direction, i.e., one first transmission component 21 is located on one side of the first roll-up component 22 in the axial direction, and the other first transmission component 21 is located on the other side of the first roll-up component 22 in the axial direction. The two first transmission components 21 can control the movement of the first curtain 23 under the drive of the drive component 10, thereby driving the first roll-up component 22 to rotate through the first curtain 23.

[0050] Each first transmission assembly 21 includes a first synchronizing element 211, a second synchronizing element 212, and a first transmission element 213. The first transmission element 213 is sleeved on the first synchronizing element 211 and the second synchronizing element 212 to complete the assembly of the first transmission assembly 21. Optionally, when the first transmission element 213 is an open synchronous belt, the open synchronous belt can be fixed with the first slider 242 in the first sliding assembly 24 to form a closed loop for the first transmission assembly 21. When the first transmission element 213 is a closed-loop synchronous belt, the first transmission assembly 21 can directly form a closed loop.

[0051] The first synchronizing element 211 is fixed to the driving element 10 and connected to the first take-up element 22. One end of the first curtain 23 can be fixed to the first take-up element 22, and the other end of the first curtain 23 can be fixed to the first sliding component 24. At the same time, the first sliding component 24 is also fixed to the first transmission element 213.

[0052] The first curtain mechanism 20 also includes a first support rod 25, which passes through and connects to the first take-up member 22. The two ends of the first support rod 25 are fixed to two first synchronization members 211 in the two first transmission components 21. That is, one end of the first support rod 25 is fixed to one first synchronization member 211, and the other end of the first support rod 25 is fixed to the other first synchronization member 211, so that the first take-up member 22 and the first synchronization member 211 are coaxially arranged. Therefore, the first synchronization member 211 is indirectly connected to the first take-up member 22 through the first support rod 25.

[0053] Based on the above structure, when the drive component 10 is working, it provides output torque as a power source, which can directly drive the first synchronizing component 211 and the first support rod 25 fixed to the first synchronizing component 211 to rotate. At the same time, it can drive the first transmission component 213 and the second synchronizing component 212 to move, thereby driving the first sliding component 24 fixed to the first transmission component 213 to move. Furthermore, the first support rod 25 can also drive the first synchronizing component 211 on the other side of the first take-up component 22 to rotate, and at the same time, it can drive the first transmission component 213 and the second synchronizing component 212 on the other side to move, thereby driving the first sliding component 24 fixed to the other side of the first transmission component 213 to move. Finally, the two first sliding components 24 together pull the first curtain 23 out from the first take-up component 22, and the first curtain 23 can drive the first take-up component 22 to rotate, thereby achieving constant force winding.

[0054] Based on this, the first curtain mechanism 20 may further include a first elastic element, which is disposed within the first take-up unit 22 and connects the first take-up unit 22 and the first support rod 25. The first elastic element enables the first support rod 25 and the first take-up unit 22 to be movably connected, avoiding a fixed connection between the two, and allowing the relative movement relationship between the first take-up unit 22 and the first support rod 25 to be adjusted throughout the entire stroke.

[0055] In this embodiment, the first elastic element can be in an elastic deformation state so that the first curtain 23 can be in a taut state when opened, ensuring that the first curtain 23 is always taut.

[0056] The second curtain mechanism 30 includes two second transmission components 31, a second take-up member 32, a second curtain 33, and a second sliding component 34. The second take-up member 32 may be cylindrical and is mainly used to support and load the second curtain 33. The two second transmission components 31 are located on opposite sides of the second take-up member 32 in the axial direction, that is, one second transmission component 31 is located on one side of the second take-up member 32 in the axial direction, and the other second transmission component 31 is located on the other side of the second take-up member 32 in the axial direction. The two second transmission components 31 can control the movement of the second curtain 33 under the drive of the two first transmission components 21, thereby driving the second take-up member 32 to rotate through the second curtain 33.

[0057] Two second transmission components 31 are disposed between two first transmission components 21. Each second transmission component 31 includes a third synchronizer 311, a fourth synchronizer 312, and a second transmission component 313. The second transmission component 313 is sleeved on the third synchronizer 311 and the fourth synchronizer 312 to complete the assembly of the second transmission component 31. Optionally, when the second transmission component 313 is an open synchronous belt, the second transmission component 31 can form a closed loop after the open synchronous belt is fixed with the second slider 342 in the second sliding component 34. When the second transmission component 313 is a closed-loop synchronous belt, the second transmission component 31 can directly form a closed loop. The third synchronizer 311 is fixed to the second synchronizer 212 and is coaxially arranged with the second synchronizer 212. That is, while the second synchronizer 212 rotates under the drive of the first transmission component 213, the second synchronizer 212 can also drive the third synchronizer 311 to rotate synchronously, thereby providing a power source for the second curtain mechanism 30.

[0058] Since the second synchronizer 212 rotates synchronously with the third synchronizer 311, the second take-up unit 32 can be connected to either the second synchronizer 212 or the third synchronizer 311. One end of the second curtain 33 is fixed to the second take-up unit 32, and the other end of the second curtain 33 is fixed to the second sliding assembly 34. At the same time, the second sliding assembly 34 is also fixed to the second transmission member 313.

[0059] The second curtain mechanism 30 also includes a second support rod 35, which passes through and connects to the second take-up unit 32. The two ends of the second support rod 35 are fixed to two second synchronizers 212 and two third synchronizers 311 of the two first transmission assemblies 21. Specifically, one end of the second support rod 35 is fixed to one second synchronizer 212 and one third synchronizer 311, while the other end is fixed to another second synchronizer 212 and another third synchronizer 311. This achieves coaxial arrangement of the second take-up unit 32 with the second synchronizers 212 and 311. Therefore, the second synchronizers 212 and 311 are indirectly connected to the second take-up unit 32 via the second support rod 35.

[0060] Based on the above structure, the power source originating from the drive member 10 causes the second synchronizing member 212 in the first transmission assembly 21 to rotate. The second synchronizing member 212 drives the third synchronizing member 311 and the second support rod 35 fixed to the third synchronizing member 311 to rotate, and simultaneously drives the second transmission member 313 and the fourth synchronizing member 312 to move, thereby driving the second sliding assembly 34 fixed to the second transmission member 313 to move. Furthermore, the second support rod 35 can also drive the third synchronizing member 311 on the other side of the second take-up member 32 to rotate, and simultaneously drive the second transmission member 313 and the fourth synchronizing member 312 on the other side to move, thereby driving the second sliding assembly 34 fixed to the other side of the second transmission member 313 to move. Finally, the two second sliding assemblies 34 together pull the second curtain 33 out of the second take-up member 32, and the second curtain 33 can drive the second take-up member 32 to rotate, thereby achieving constant force winding.

[0061] Based on this, the second curtain mechanism 30 may further include a second elastic element, which is disposed within the second take-up unit 32 and connects the second take-up unit 32 and the second support rod 35. The second elastic element enables a movable connection between the second support rod 35 and the second take-up unit 32, avoiding a fixed connection and allowing adjustment of the relative movement relationship between the second take-up unit 32 and the second support rod 35 throughout the entire stroke.

[0062] In this embodiment, the second elastic element can be in an elastic deformation state so that the second curtain 33 can be in a taut state when opened, ensuring that the second curtain 33 is always taut.

[0063] In summary, this embodiment uses only one driving component 10, which can normally drive the first curtain mechanism 20 to move. At this time, the first synchronizing component 211 acts as the driving wheel of the first curtain mechanism 20, and the second synchronizing component 212 acts as the driven wheel of the first curtain mechanism 20. Simultaneously, the second synchronizing component 212 can drive the second curtain mechanism 30 to move synchronously. At this time, the third synchronizing component 311 acts as the driving wheel of the second curtain mechanism 30, and the fourth synchronizing component 312 acts as the driven wheel of the second curtain mechanism 30. The driven wheel of the first curtain mechanism 20 and the driving wheel of the second curtain mechanism 30 rotate on the same shaft, achieving the same angular velocity, thereby ensuring the synchronicity of the operation of the first curtain 23 and the second curtain 33. Ultimately, one driving component 10 can simultaneously drive the opening or closing of the first curtain 23 and the second curtain 33. Compared with related technologies, this directly reduces one driving component 10, achieving a one-to-two function, reducing costs, noise, space occupation, and weight. Meanwhile, using a single drive unit 10 can improve the synchronization of the movements of the two curtain mechanisms. In this case, the sunshade assembly 1 can also be referred to as a single-motor double sunshade structure.

[0064] In addition, the use of a synchronizing component in conjunction with a transmission component results in more precise and stable transmission, lower operating resistance, less transmission noise, and lower weight compared to the flexible shaft transmission structure in related technologies.

[0065] In this embodiment, the first curtain 23 has a first starting position and a first ending position, and the second curtain 33 has a second starting position and a second ending position. During the opening or closing of the sunshade assembly 1, the movement time of the first curtain 23 between the first starting position and the first ending position is equal to the movement time of the second curtain 33 between the second starting position and the second ending position.

[0066] The first curtain 23 has a starting position and an ending position during its movement, and the second curtain 33 also has a starting position and an ending position during its movement. Therefore, in this embodiment, the starting position of the first curtain 23 is called the first starting point position, and the ending position is called the first ending point position. The starting position of the second curtain 33 is called the second starting point position, and the ending position is called the second ending point position.

[0067] Since this application utilizes a single drive unit 10 to control the synchronous movement of the first curtain 23 and the second curtain 33, their starting times are the same. This embodiment also allows the movement time of the first curtain 23 between the first starting position and the first ending position to be equal to the movement time of the second curtain 33 between the second starting position and the second ending position. That is, the movement time of the first curtain 23 throughout the entire process is the same as the movement time of the second curtain 33 throughout the entire process, thereby ensuring that their ending times are also the same.

[0068] In summary, this embodiment uses a driving component 10 to drive two curtains with two strokes, enabling the first curtain 23 and the second curtain 33 to simultaneously complete the closing and opening actions. That is, the first curtain 23 and the second curtain 33 start moving at the same time and stop moving at the same time, so that the two curtains open or close at the same time.

[0069] In this embodiment, the sunshade assembly 1 satisfies the following conditions: Wherein, R1 is the radius of the first synchronizing element 211, S1 is the travel distance of the first curtain 23 between the first starting position and the first ending position, α is the angular velocity output by the driving element 10, and T is the travel time of the first curtain 23 between the first starting position and the first ending position.

[0070] Wherein, R2 is the radius of the second synchronization element 212, R3 is the radius of the third synchronization element 311, and S2 is the travel distance of the second curtain 33 between the second starting position and the second ending position.

[0071] As can be seen from the content, the known conditions in this embodiment are the movement distance of the first curtain 23 between the first starting position and the first ending position, i.e., S1; the movement distance of the second curtain 33 between the second starting position and the second ending position, i.e., S2; the angular velocity output by the drive member 10, i.e., α; and the movement time of the first curtain 23 between the first starting position and the first ending position and the movement time of the second curtain 33 between the second starting position and the second ending position, i.e., T.

[0072] After knowing the above conditions, because of the linear velocity of the first synchronizing element 211 Since the linear velocity V1 of the first synchronizing element 211 is V1 = α1 × R1, and α1 = α, where α1 is the angular velocity of the first synchronizing element 211, therefore... Therefore, it can be seen that after knowing the above conditions, the radius R1 of the first synchronization element 211 is a fixed value and cannot be changed. At this time, R1 can also be understood as a known condition.

[0073] Based on this, since the linear velocity V1 of the first synchronizing element 211 is the same as the linear velocity V2 of the second synchronizing element 212, therefore α2 is the angular velocity of the second synchronizer 212. Since the third synchronizer 311 is coaxial with the second synchronizer 212, the angular velocity α3 of the third synchronizer 311 is the same as the angular velocity α2 of the second synchronizer 212. Simultaneously, the linear velocity of the third synchronizer 311... And because so Therefore, it can be found that R2 and R3 satisfy a certain ratio condition, and the value of one can be obtained by knowing the value of the other.

[0074] In summary, R1 can be calculated based on the known conditions, and R2 and R3 can be calculated by knowing only one of them, thus enabling more accurate simultaneous start and end of the two curtains' travel.

[0075] Optionally, there is no necessary relationship between the travel S1 of the first curtain 23 and the travel S2 of the second curtain 33, i.e., S1 = S2, or S1 > S2, or S1 < S2. In this embodiment, S1 > S2 is used only for illustrative purposes. In this case, the first curtain 23 can be called the rear sunshade curtain and the second curtain 33 can be called the front sunshade curtain.

[0076] Optionally, upon obtaining as well as Under the premise that the transmission ratio of the synchronizing element of the first curtain mechanism 20 is also known... The ratio of the synchronous transmission ratio of the second curtain mechanism 30 The ratio of the two curtains is such that, when the input parameters are the stroke S1 of the first curtain 23, the stroke S2 ​​of the second curtain 33, the output angular velocity α of the drive unit 10, and the opening and closing times T of the two curtains, and on the premise that the radius R1 of the first synchronizing unit 211 is calculated, the radius R2 of the second synchronizing unit 212 and the radius R3 of the third synchronizing unit 311 can be calculated.

[0077] In summary, by driving the curtains in both the front and rear strokes with a single drive unit 10, and by setting the transmission ratio of the synchronization components of the two curtains, the radius of each synchronization component can be calculated, thus enabling the two curtains to simultaneously complete the closing and opening actions.

[0078] In this embodiment, the sunshade assembly 1 satisfies the following condition: α1 = α, where α is the angular velocity output by the drive component 10, and α1 is the angular velocity of the first synchronizing component 211.

[0079] Wherein, α2 is the angular velocity of the second synchronization element 212, α3 is the angular velocity of the third synchronization element 311, R1 is the radius of the first synchronization element 211, and R2 is the radius of the second synchronization element 212.

[0080] Wherein, α4 ​​is the angular velocity of the fourth synchronization element 312, R3 is the radius of the third synchronization element 311, and R4 is the radius of the fourth synchronization element 312.

[0081] Given the known radii R1 of the first synchronization element 211, R2 of the second synchronization element 212, R3 of the third synchronization element 311, and R4 of the fourth synchronization element 312, and based on the calculation process of the above embodiment, it can be known that α1 = α. because so This allows us to obtain the angular velocities of all the synchronizing components, thus providing more accurate angular velocity parameters between different synchronizing components and making it easier to control the simultaneous opening and closing of the two curtains.

[0082] In this embodiment, the sunshade assembly 1 satisfies the following conditions: Wherein, V1 is the linear velocity of the first synchronizing element 211, V2 is the linear velocity of the second synchronizing element 212, S1 is the travel distance of the first curtain 23 between the first starting position and the first ending position, T is the travel time of the first curtain 23 between the first starting position and the first ending position, R1 is the radius of the first synchronizing element 211, and α is the angular velocity output by the driving element 10.

[0083] Wherein, V3 is the linear velocity of the third synchronization element 311, V4 is the linear velocity of the fourth synchronization element 312, S2 is the travel distance of the second curtain 33 between the second starting position and the second ending position, R2 is the radius of the second synchronization element 212, and R3 is the radius of the third synchronization element 311.

[0084] By combining the various calculation processes described in the above embodiments, it is already possible to obtain... This allows us to obtain the linear velocity of all the synchronizing components, thus providing a more accurate understanding of the linear velocity parameters between different synchronizing components, which is more conducive to controlling the simultaneous opening and closing of the two curtains.

[0085] Furthermore, this application has plotted the various parameters obtained above into the following table, as shown in Table 1, which provides a clearer and more intuitive understanding of the angular velocity and linear velocity of each synchronizing element.

[0087]

[0088] In this embodiment, when the first curtain 23 and the second curtain 33 are opened, the opening direction of the first curtain 23 is the same as or opposite to the opening direction of the second curtain 33.

[0089] Based on the simultaneous opening and closing of the first curtain 23 and the second curtain 33, this embodiment can also control the opening and closing directions of the first curtain 23 and the second curtain 33. For example, the opening direction of the first curtain 23 can be the same as or opposite to the opening direction of the second curtain 33. In other words, when the opening direction of the first curtain 23 is the same as the opening direction of the second curtain 33, the first curtain 23 and the second curtain 33 open in the same direction. When the opening direction of the first curtain 23 is opposite to the opening direction of the second curtain 33, the first curtain 23 and the second curtain 33 open relative to each other. This embodiment is only illustrated with the example of the first curtain 23 and the second curtain 33 opening in the same direction, which facilitates the optimization of the structure of the sunshade assembly 1, thereby facilitating the installation of the sunshade assembly 1 on the vehicle body 4.

[0090] Furthermore, based on the limitation of the opening direction, when the first curtain 23 and the second curtain 33 are closed, the closing direction of the first curtain 23 is the same as or opposite to the closing direction of the second curtain 33.

[0091] Optionally, the opening and closing direction can be changed by altering the position of the fourth synchronizer 312. For example, when the fourth synchronizer 312 is farther away from the first synchronizer 211 relative to the third synchronizer 311, the opening and closing directions of the first curtain 23 and the second curtain 33 are the same. When the fourth synchronizer 312 is closer to the first synchronizer 211 relative to the third synchronizer 311, the opening and closing directions of the first curtain 23 and the second curtain 33 are opposite.

[0092] Optionally, the positions of the first curtain mechanism 20 and the second curtain mechanism 30 can be changed to swap the front and rear sunshades.

[0093] In this embodiment, both the first synchronizing element 211 and the second synchronizing element 212 include a synchronizing pulley or a threaded pulley. When both the first synchronizing element 211 and the second synchronizing element 212 include the synchronizing pulley, the first transmission element 213 includes a synchronizing belt. When both the first synchronizing element 211 and the second synchronizing element 212 include the threaded pulley, the first transmission element 213 includes a pull cable.

[0094] And / or, both the third synchronization element 311 and the fourth synchronization element 312 include a synchronization pulley or a threaded pulley. When both the third synchronization element 311 and the fourth synchronization element 312 include the synchronization pulley, the second transmission element 313 includes a synchronization belt. When both the third synchronization element 311 and the fourth synchronization element 312 include the threaded pulley, the second transmission element 313 includes a pull cable.

[0095] The four synchronizing components provided in this embodiment include, but are not limited to, synchronizing pulleys or reels. Correspondingly, the two transmission components provided in this embodiment include, but are not limited to, synchronizing belts or pull cables. Therefore, the transmission structure using synchronizing pulleys and synchronizing belts, or reels and pull cables, provides more precise and stable transmission, lower running resistance, less transmission noise, and lower weight compared to the flexible shaft transmission structure in related technologies. This embodiment only illustrates the use of synchronizing pulleys as the four synchronizing components and synchronizing belts as the two transmission components. Optionally, the first transmission component 213 is connected to the first synchronizing component 211 and the second synchronizing component 212 via meshing, and the second transmission component 313 is connected to the third synchronizing component 311 and the fourth synchronizing component 312 via meshing.

[0096] In this embodiment, the first sliding assembly 24 includes a first pull rod 241 and two first sliders 242 fixed to opposite ends of the first pull rod 241. The first pull rod 241 is fixed to the other end of the first curtain 23, and each first slider 242 is fixed to a first transmission member 213 in a first transmission assembly 21. And / or, the second sliding assembly 34 includes a second pull rod 341 and two second sliders 342 fixed to opposite ends of the second pull rod 341. The second pull rod 341 is fixed to the other end of the second curtain 33, and each second slider 342 is fixed to a second transmission member 313 in a second transmission assembly 31.

[0097] Both the first sliding assembly 24 and the second sliding assembly 34 can consist of a pull rod and two sliders. The first pull rod 241 is fixed to the other end of the first curtain 23, and the two first sliders 242 are fixed to the opposite ends of the first pull rod 241. Each first slider 242 is fixed to a first transmission member 213 in the first transmission assembly 21. Thus, when the first transmission member 213 moves, it can pull the first sliders 242 to drive the first pull rod 241 to move, thereby driving the other end of the first curtain 23 to move, realizing the opening or closing of the first curtain 23.

[0098] Similarly, the second pull rod 341 is fixed to the other end of the second curtain 33, and two second sliders 342 are fixed to the opposite ends of the second pull rod 341, with each second slider 342 fixed to a second transmission member 313 in the second transmission assembly 31. Thus, when the second transmission member 313 moves, it can pull the second sliders 342 to drive the second pull rod 341 to move, thereby driving the other end of the second curtain 33 to move, thus opening or closing the second curtain 33.

[0099] In summary, by using the combination of the pull rod and the slider, the other end of the curtain can be connected to the transmission component, thereby realizing the opening and closing of the curtain.

In this case, glass 2 can be a windshield, rear window, side window, etc. In this case, the curtain can cover or expose glass 2 under the traction action of various structures to achieve the purpose of sunshade. Specifically, when the curtain is open, it can cover glass 2 to block light. When the curtain is closed, it can expose glass 2 to allow light to pass through. The glass assembly 3 provided in this embodiment, by adopting the sunshade assembly 1 provided in the above embodiment of this application, can simultaneously drive the opening or closing of the first curtain 23 and the second curtain 33 with one drive member 10. Compared with related technologies, it can directly reduce one drive member 10, realize the function of one-to-two, reduce cost, reduce movement noise and space occupation, and reduce weight. At the same time, using one drive member 10 can improve the synchronization of the movement of the two curtain mechanisms. In addition, the use of a synchronizing component in conjunction with a transmission component results in more precise and stable transmission, lower operating resistance, less transmission noise, and lower weight compared to the flexible shaft transmission structure in related technologies.

In this case, the glass 2 of the glass assembly 3 is the windshield, rear window, side window, etc. The rest of the glass assembly 3 is located below the glass 2, that is, inside the vehicle. The curtain of the sunshade assembly 1 can cover the glass 2 or open the glass 2 by the action of the slider.

[0104] The vehicle 5 provided in this embodiment, by employing the glass assembly 3 as described in the above-described embodiments of this application, can simultaneously drive the opening or closing of the first curtain 23 and the second curtain 33 via a single drive member 10. Compared to related technologies, this directly reduces the need for a single drive member 10, achieving a one-to-two function, reducing costs, noise, space occupation, and weight. Furthermore, using a single drive member 10 improves the synchronization of the two curtain mechanisms. In addition, the combination of a synchronizing member and a transmission member provides more precise and stable transmission, lower operating resistance, less transmission noise, and lower weight compared to the flexible shaft transmission structure in related technologies.
