Vehicle, sunroof assembly, and roller blind mechanism

Abstract

This invention relates to a vehicle, a sunroof assembly, and a roller blind mechanism. When the first and second rollers rotate, they drive an annular winding belt to reciprocate along its extended trajectory, thereby enabling the winding or unwinding of a sunshade wrapped around the annular winding belt. Furthermore, when the sunshade is wound onto the outer wall of the annular winding belt, compared to the traditional method of winding the sunshade using a roller, the annular winding belt extends the horizontal circumference of the sunshade, effectively reducing the overall vertical dimension of the wound sunshade and minimizing the vertical space required.

Description

Technical Field

[0001] This invention relates to the field of vehicle engineering technology, and in particular to a vehicle, sunroof assembly, and roller blind mechanism. Background Technology

[0002] The sunshade of the sunroof assembly can be opened or closed as needed. Therefore, a roller is needed to retract the sunshade, that is, to retract the sunshade by rotating the roller. As the design size of the sunroof becomes larger, the length of the sunshade also becomes larger, resulting in a larger overall diameter of the roller in the vertical direction after retracting the sunshade, which occupies more design space in the vertical direction. Summary of the Invention

[0003] Therefore, it is necessary to provide a vehicle, sunroof assembly, and roller blind mechanism to address the issue of occupying a large amount of design space in the vertical direction.

[0004] The technical solution is as follows:

[0005] On the one hand, a roller blind mechanism is provided, capable of rolling up or releasing a sunshade, including:

[0006] First winding reel;

[0007] The second winding wheel is spaced apart from the first winding wheel along the direction of movement of the sunshade; and

[0008] The annular winding belt has frictional engagement with the first winding wheel and the second winding wheel on both sides, respectively, so that the annular winding belt can reciprocate along the extension trajectory of the annular winding belt to drive the sunshade curtain wound on the annular winding belt to be wound or released.

[0009] The technical solution will be further explained below:

[0010] In one embodiment, the winding mechanism further includes a support frame disposed within the annular winding belt, the support frame being tensioned to at least a portion of the annular winding belt.

[0011] In one embodiment, the support frame includes a first tensioning part, a second tensioning part, and a connecting part. The first tensioning part and the second tensioning part are arranged at a distance from each other and are connected by the connecting part. The first tensioning part is tensioned to one side of the annular winding belt, and the second tensioning part is tensioned to the other side of the annular winding belt. The connecting part is spaced apart from the annular winding belt.

[0012] In one embodiment, the outer side wall of the first winding wheel and the outer side wall of the second winding wheel are both provided with first transmission teeth, and the inner side wall of the annular winding belt is provided with second transmission teeth that engage with the first transmission teeth.

[0013] In one embodiment, the roller blind mechanism further includes a spindle and a transmission assembly, wherein the first take-up wheel is rotatably mounted on the spindle, and the transmission assembly is connected to the first take-up wheel to drive the first take-up wheel to rotate around the central axis of the spindle.

[0014] In one embodiment, the transmission assembly includes a transmission cover, a torsion reset member, and a drive wheel with a cavity. The drive wheel is rotatably sleeved on the outside of the mandrel. The first take-up wheel is disposed on one side of the drive wheel. The transmission cover is disposed on the side of the drive wheel opposite to the first take-up wheel. The transmission cover is fixedly connected to the drive wheel and rotatably sleeved on the outer wall of the mandrel. The torsion reset member is at least partially disposed in the cavity, and one side of the torsion reset member is fixedly connected to the transmission cover. The other side of the torsion reset member is fixedly connected to the first take-up wheel, so that the first take-up wheel can rotate synchronously and in the same direction as the transmission cover.

[0015] In one embodiment, the transmission assembly further includes an annular transmission belt and a transmission wheel. The transmission wheel and the drive wheel are spaced apart relative to each other along the moving direction of the sunshade. The two sides of the annular transmission belt are respectively in frictional engagement with the drive wheel and the transmission wheel, so that the annular transmission belt can reciprocate along the extension trajectory of the annular transmission belt to drive the drive wheel to rotate.

[0016] In one embodiment, the outer side wall of the drive wheel and the outer side wall of the transmission wheel are both provided with a third transmission tooth, and the inner side wall of the annular transmission belt is provided with a fourth transmission tooth that engages with the third transmission tooth.

[0017] In one embodiment, the roller blind mechanism further includes a pulling member and a slider. The pulling member is disposed opposite to the annular winding belt along the moving direction of the sunshade. The pulling member is connected to the side of the sunshade away from the annular winding belt. One end of the pulling member is connected to the slider, which is capable of reciprocating along the moving direction of the sunshade. The slider is connected to the annular transmission belt to drive the annular transmission belt to reciprocate.

[0018] In one embodiment, the tension transmitted from the torsion reset member to the pulling member via the first take-up wheel, the annular take-up belt, and the sunshade is equal to the tension transmitted from the torsion reset member to the pulling member via the transmission cover, the drive wheel, the annular transmission belt, and the slider.

[0019] In one embodiment, the roller blind mechanism further includes an adapter connected to the annular transmission belt, and one end of the pulling member and the slider are both connected to the adapter.

[0020] In one embodiment, the transmission assembly includes a linear moving member, a fixing member, and a torsional energy storage member. The linear moving member is disposed opposite to the annular winding belt and is capable of reciprocating along the moving direction of the sunshade. The linear moving member is connected to the side of the sunshade away from the annular winding belt. The fixing member is spaced apart from the first winding wheel along the axial direction of the mandrel. The torsional energy storage member is disposed between the fixing member and the first winding wheel, and the opposite sides of the torsional energy storage member are respectively connected to the fixing member and the first winding wheel.

[0021] In one embodiment, the roller blind mechanism further includes a mounting base, on which both the first winding wheel and the second winding wheel are rotatably mounted.

[0022] On another front, a sunroof assembly is provided, including a sunshade and a roller blind mechanism, the roller blind mechanism being capable of rolling up or releasing the sunshade.

[0023] On the other hand, a vehicle is provided, including the aforementioned sunroof assembly.

[0024] In the vehicle, sunroof assembly, and roller blind mechanism described in the above embodiments, when the first and second rollers rotate, the annular winding belt reciprocates along its extended trajectory, thereby winding or releasing the sunshade wrapped around it. Furthermore, when the sunshade is wound onto the outer wall of the annular winding belt, compared to the traditional method of winding the sunshade using a roller, the annular winding belt extends the horizontal circumference of the sunshade, effectively reducing the overall vertical dimension of the wound sunshade and minimizing the vertical space required.

[0037] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] In one embodiment, a vehicle is provided, comprising a body (not shown) and a sunroof assembly 10, wherein the sunroof assembly 10 is mounted on the top of the body by means of snap-fit ​​or similar means.

[0039] like Figure 1 As shown, specifically, the skylight assembly 10 includes a sunshade 200 and a roller blind mechanism 100. The roller blind mechanism 100 can roll up or release the sunshade 200, thereby enabling the skylight assembly 10 to be covered or opened as needed. Furthermore, after the roller blind mechanism 100 rolls up the sunshade 200, its overall vertical dimension becomes smaller, occupying less design space in the vertical direction.

[0040] It is understood that the sunshade curtain 200 can be any existing curtain fabric, etc., and the sunshade curtain 200 can be rolled up or released by the roller blind mechanism 100.

[0041] It should be noted that the skylight assembly 10 also includes components such as the window frame, which can be constructed using existing structures and will not be described in detail here.

[0042] like Figure 2 As shown, in one embodiment, the roller blind mechanism 100 includes a first take-up roller 110, a second take-up roller 120, and an annular take-up belt 130.

[0043] Among them, the first winding wheel 110 and the second winding wheel 120 are along the moving direction of the sunshade 200 (e.g., Figure 1 , Figure 5 and Figure 8 The relative spacing is set by either arrow pointing in direction A.

[0044] It should be noted that the direction of movement of the sunshade 200 refers to the direction of movement when the sunshade 200 is covering or opening.

[0045] The annular winding belt 130 has frictional engagement with the first winding wheel 110 and the second winding wheel 120 on both sides. Specifically, one side of the annular winding belt 130 is fitted onto the outer wall of the first winding wheel 110, and the other side is fitted onto the outer wall of the second winding wheel 120. The first and second winding wheels 110 and 120 tension the opposite sides of the annular winding belt 130, allowing the rotation of the first and second winding wheels 110 to drive the annular winding belt 130 along its extended trajectory. When the first and second winding wheels 110 and 120 rotate, the annular winding belt 130 reciprocates along its extended trajectory, thereby winding up or unwinding the sunshade curtain 200 wound around the annular winding belt 130. Furthermore, when the sunshade 200 is rolled up onto the outer wall of the annular winding belt 130, compared to the traditional method of using a roller to roll up the sunshade 200, the annular winding belt 130 extends the horizontal circumference of the sunshade 200, thereby effectively reducing the overall vertical dimension of the sunshade 200 after it is rolled up, and occupying less design space in the vertical direction.

[0046] The winding circumference refers to the length of the sunshade curtain 200 that can be wound up in one revolution of the circular winding belt 130.

[0047] It is understandable that reciprocating along the extended trajectory of the annular take-up belt 130 means that a portion of the annular take-up belt 130 moves along its annular trajectory, thereby enabling the sunshade 200, one end of which is fixed to the annular take-up belt 130, to be rolled onto or released from the annular take-up belt 130. Furthermore, reciprocating along the extended trajectory of the annular take-up belt 130 can be achieved by changing the rotation direction of the first take-up wheel 110 and the second take-up wheel 120.

[0048] In one embodiment, the length of the sunshade 200 is 1200mm, and the two sides of the sunshade 200 have edge strips with a thickness of 0.6mm. The thickness of the sunshade 200 is 0.6mm. Traditionally, after the sunshade 200 is rolled up using a roller, its vertical diameter is 47mm, which occupies a lot of design space in the vertical direction. In order to avoid occupying too much design space in the vertical direction, the traditional approach is to reduce the area of ​​the skylight assembly 10 and thus reduce the size of the skylight to shorten the length of the sunshade 200, which affects the skylight view, or to design the sunshade 200 as a two-piece double-opening type for separate rolling, which increases the design cost. However, when the sunshade 200 is rolled up by the roller blind mechanism 100 in the above embodiment, the center distance between the first rolling wheel 110 and the second rolling wheel 120 (e.g., Figure 3As shown in L), the diameter is 40mm. The diameters of the first winding wheel 110 and the second winding wheel 120 are both 9.6mm. After the annular winding belt 130 winds up the sunshade 200, its outer diameter in the vertical direction (as shown in L) is 40mm. Figure 3 The diameter (D) is 25mm, which can save 22mm of design space in the vertical direction. It does not require reducing the size of the skylight to shorten the length of the sunshade 200, will not affect the skylight view, and does not increase the design cost.

[0049] like Figure 3 and Figure 4 As shown, the winding mechanism further includes a support frame 140. The support frame 140 is disposed within the annular winding belt 130, and is tensioned to at least a portion of the annular winding belt 130. This allows the support frame 140 to support and tension the annular winding belt 130, ensuring that the center distance between the first winding wheel 110 and the second winding wheel 120 remains unchanged. This ensures that the annular winding belt 130 remains taut and prevents slackness, thereby ensuring that the sunshade 200 remains taut for easy winding.

[0050] In this case, the overall outline shape of the support frame 140 may match the internal outline of the annular winding belt 130, or a portion of the outline shape of the support frame 140 may match the internal outline of the annular winding belt 130.

[0051] like Figure 3 and Figure 4As shown, in one embodiment, the support frame 140 includes a first tensioning portion 141, a second tensioning portion 142, and a connecting portion 143. The first tensioning portion 141 and the second tensioning portion 142 are disposed at a distance from each other, and are connected by the connecting portion 143. That is, the connecting portion 143 is disposed between the first tensioning portion 141 and the second tensioning portion 142, and the two opposite sides of the connecting portion 143 are respectively connected to the first tensioning portion 141 and the second tensioning portion 142. The first tensioning part 141 is tensioned to one side of the annular take-up belt 130, and the second tensioning part 142 is tensioned to the other side of the annular take-up belt 130. Thus, the first tensioning part 141 and the second tensioning part 142 respectively support and tension the opposite sides of the annular take-up belt 130, ensuring that the center distance between the first take-up roller 110 and the second take-up roller 120 does not change. This ensures that the annular take-up belt 130 remains taut and prevents slackness, thereby ensuring that the sunshade 200 remains taut for easy winding. Simultaneously, the connecting part 143 is spaced apart from the annular take-up belt 130, meaning there is a gap between them. This reduces the contact area between the annular take-up belt 130 and the support frame 140, thereby reducing the movement resistance of the annular take-up belt 130 and making its operation smoother.

[0052] The contour of the contact portion between the first tensioning portion 141 and the annular winding belt 130 can match the contour of the contact portion between the first take-up wheel 110 and the annular winding belt 130, which not only supports and tensions the annular winding belt 130, but also does not affect the operation of the annular winding belt 130; the contour of the contact portion between the second tensioning portion 142 and the annular winding belt 130 can match the contour of the contact portion between the second take-up wheel 120 and the annular winding belt 130, which not only supports and tensions the annular winding belt 130, but also does not affect the operation of the annular winding belt 130.

[0053] The connecting part 143 can be an arc-shaped connecting spoke or a connecting plate.

[0054] The first tensioning part 141, the second tensioning part 142 and the connecting part 143 can be made by integral molding, or they can be molded separately and then assembled by welding or other methods.

[0055] Furthermore, the frictional engagement between the first take-up roller 110 and the second take-up roller 120 and the annular take-up belt 130 only needs to satisfy the requirement that the rotation of the first take-up roller 110 and the rotation of the second take-up roller 120 can drive the annular take-up belt 130 to operate.

[0056] In one embodiment, the outer walls of both the first take-up reel 110 and the second take-up reel 120 are provided with first drive teeth (not shown), and the inner wall of the annular take-up belt 130 is provided with second drive teeth 131 that mesh with the first drive teeth. Thus, by utilizing the mutual meshing of the first drive teeth and the second drive teeth 131, the annular take-up belt 130 can be stably and reliably driven to operate when the first take-up reel 110 and the second take-up reel 120 rotate, preventing slippage.

[0057] Of course, the annular winding belt 130 may also include two interlocking annular belts. The outer annular belt is connected to one side of the sunshade 200 by means of bonding, screwing, etc., and the inner annular belt is provided with a second transmission tooth 131. The outer annular belt and the inner annular belt are connected by means of hot pressing, bonding, etc.

[0058] like Figure 1 , Figure 2 and Figure 5 As shown, the roller blind mechanism 100 also includes a spindle 150 and a transmission assembly 160. The first take-up roller 110 is rotatably mounted on the spindle 150 via bearings and other components, thus supporting and mounting the first take-up roller 110 using the spindle 150. Furthermore, the transmission assembly 160 is connected to the first take-up roller 110, thereby driving the first take-up roller 110 to rotate around the central axis of the spindle 150, which in turn causes the annular take-up belt 130 to rotate, thereby rolling up or releasing the sunshade 200.

[0059] In addition, to prevent the first take-up roller 110 from moving along the axial direction of the mandrel 150 after being sleeved on the outside of the mandrel 150, a hole can be provided on the mandrel 150, and the first take-up roller 110 can be limited by the insertion and engagement of the pin with the hole; or a slot can be provided on the mandrel 150, and the first take-up roller 110 can be limited by the engagement and engagement of the clamp or buckle with the slot.

[0060] In one embodiment, when the transmission assembly 160 drives the first winding wheel 110 to rotate clockwise (or counterclockwise), the annular winding belt 130 winds up the sunshade 200, that is, winds the sunshade 200 onto the outer wall of the annular winding belt 130; when the transmission assembly 160 drives the first winding wheel 110 to rotate counterclockwise (or clockwise), the annular winding belt 130 releases the sunshade 200, that is, releases the sunshade 200 wound onto the outer wall of the annular winding belt 130.

[0061] Optionally, the transmission assembly 160 drives the first take-up wheel 110 to rotate around the central axis of the mandrel 150. It can be driven directly by a servo motor or other rotary drive components, or it can convert other forms of motion into the power to drive the first take-up wheel 110 to rotate through the transmission of intermediate components.

[0062] like Figure 5 and Figure 6 As shown, in one embodiment, the transmission assembly 160 includes a transmission cover 161, a torsion reset member 162, and a drive wheel 163 with a cavity. Optionally, the drive wheel 163 may be a hollow cylinder with openings at both ends. The drive wheel 163 is rotatably sleeved on the outside of the mandrel 150. A first winding wheel 110 is disposed on one side of the drive wheel 163, and the transmission cover 161 is disposed on the side of the drive wheel 163 opposite to the first winding wheel 110; that is, the first winding wheel 110 and the transmission cover 161 are respectively disposed on opposite sides of the drive wheel 163. The transmission cover 161 is fixedly connected to the drive wheel 163 and rotatably sleeved on the outer wall of the mandrel 150 via bearings or other components, thereby allowing the transmission cover 161 and the drive wheel 163 to rotate synchronously and in the same direction relative to the mandrel 150 around the central axis of the mandrel 150. The torsion reset member 162 is at least partially disposed in the cavity. One side of the torsion reset member 162 is fixedly connected to the transmission cover 161 by means of snap-fit ​​or screw-fit, and the other side of the torsion reset member 162 is fixedly connected to the first take-up wheel 110 by means of snap-fit ​​or screw-fit. This allows the torque of the transmission cover 161 to be transmitted to the first take-up wheel 110 through the torsion reset member 162, so that the first take-up wheel 110 can rotate synchronously and in the same direction as the transmission cover 161. Then, when the drive wheel 163 rotates, it synchronously drives the transmission cover 161 and the first take-up wheel 110 to rotate in the same direction, thereby causing the second take-up wheel 120 to rotate and the annular take-up belt 130 to run.

[0063] The transmission cover 161 and the drive wheel 163 can be integrally formed, or they can be formed separately and then assembled by welding or other processes.

[0064] The torsion reset member 162 can be a torsion spring or other element capable of torsion energy storage and reset.

[0065] like Figure 1 and Figure 8As shown, the transmission assembly 160 further includes an annular transmission belt 164 and a transmission wheel (not shown). The transmission wheel and the drive wheel 163 are spaced apart relative to each other along the direction of movement of the sunshade 200. The two sides of the annular transmission belt 164 are in frictional engagement with the drive wheel 163 and the transmission wheel, respectively. Specifically, one side of the annular transmission belt 164 is fitted onto the outer wall of the drive wheel 163, and the other side is fitted onto the outer wall of the transmission wheel. The drive wheel 163 and the transmission wheel tension the opposite sides of the annular transmission belt 164, allowing the annular transmission belt 164 to reciprocate along its extended trajectory, thereby driving the drive wheel 163 to rotate.

[0066] It is understandable that reciprocating motion along the extended track of the annular transmission belt 164 means that a portion of the annular transmission belt 164 moves along its annular track, thereby causing the drive wheel 163 to rotate under the action of friction. Furthermore, reciprocating motion along the extended track of the annular transmission belt 164 can drive the drive wheel 163 to rotate clockwise or counterclockwise.

[0067] Furthermore, both the outer wall of the drive wheel 163 and the outer wall of the transmission wheel are provided with a third transmission tooth (not shown), and the inner wall of the annular transmission belt 164 is provided with a fourth transmission tooth (not shown) that meshes with the third transmission tooth. In this way, by utilizing the mutual meshing of the third and fourth transmission teeth, the annular transmission belt 164 can stably and reliably drive the drive wheel 163 to rotate when it is running, thus avoiding slippage.

[0068] In order to make the annular transmission belt 164 rotate, corresponding transmission teeth can be set on the outer side of the annular transmission belt 164. By using the meshing of the gear and the transmission teeth, the annular transmission belt 164 can be driven to reciprocate when the gear rotates. Alternatively, the annular transmission belt 164 can be driven to reciprocate by the extension and retraction of the telescopic rod of the hydraulic cylinder or pneumatic cylinder. It is only necessary to satisfy the requirement that the annular transmission belt 164 can be driven to move and drive the drive wheel 163 to rotate.

[0069] In one embodiment, the roller blind mechanism 100 further includes a slider 165 that can reciprocate along the moving direction of the sunshade 200. The slider 165 is connected to an annular transmission belt 164, so that when the slider 165 reciprocates along the moving direction of the sunshade 200, it can drive the annular transmission belt 164 to reciprocate, thereby driving the drive wheel 163 to rotate.

[0070] The reciprocating movement of slider 165 along the moving direction of sunshade curtain 200 can be achieved by a linear motor drive or by a cable pull, as long as it satisfies the requirement that slider 165 can reciprocate linearly along the moving direction of sunshade curtain 200.

[0071] like Figure 1 As shown, in one embodiment, the roller blind mechanism 100 further includes a pulling member 170, which can be in the form of a pulling rod or a pulling strip. The pulling member 170 is positioned opposite the annular winding belt 130 along the moving direction of the sunshade 200. The pulling member 170 is connected to the side of the sunshade 200 away from the annular winding belt 130 by means of bonding, screwing, or other methods. Therefore, when the pulling member 170 moves, it can synchronously drive the sunshade 200 to move, thereby enabling the skylight to be either covered or opened. Furthermore, one end of the pulling member 170 is connected to the slider 165 by means of snap-fit ​​or screw connection. In this way, when the slider 165 moves back and forth along the moving direction of the sunshade 200, it can synchronously drive the pulling member 170 to move back and forth along the moving direction of the sunshade 200 and synchronously drive the annular transmission belt 164 to rotate. Then, the annular transmission belt 164 drives the drive wheel 163 to rotate, which in turn drives the transmission cover 161 and the first winding wheel 110 to rotate synchronously in the same direction, thereby synchronously driving the annular winding belt 130 to wind up or release the sunshade 200.

[0072] Optionally, when the slider 165 moves along the direction in which the sunshade 200 covers the skylight, it can simultaneously drive the pull member 170 to move along the direction in which the sunshade 200 covers the skylight, thereby driving the sunshade 200 to cover the skylight. Simultaneously, it can also drive the annular transmission belt 164 to rotate along the direction in which the sunshade 200 covers the skylight. In turn, the annular transmission belt 164 drives the drive wheel 163 to rotate clockwise, which in turn drives the transmission cover 161 and the first winding wheel 110 to rotate clockwise, thereby simultaneously driving the annular winding belt 130 to release the sunshade 200 to cover the skylight. When the slider 165 moves in the direction of opening the skylight of the sunshade 200, it can simultaneously drive the pull member 170 to move in the same direction, thereby opening the skylight. It also simultaneously drives the annular transmission belt 164 to rotate in the same direction, which in turn drives the drive wheel 163 to rotate counterclockwise. This, in turn, drives the transmission cover 161 and the first winding wheel 110 to rotate counterclockwise, thereby simultaneously driving the annular winding belt 130 to wind up the sunshade 200 to open the skylight.

[0073] Furthermore, the tension transmitted from the torsion reset member 162 to the pulling member 170 via the first take-up wheel 110, the annular take-up belt 130, and the sunshade 200 is equal to the tension transmitted from the torsion reset member 162 to the pulling member 170 via the transmission cover 161, the drive wheel 163, the annular transmission belt 164, and the slider 165. Thus, force balance is achieved through the opposing and equal tensions between the two forces, thereby tensioning the sunshade 200 and preventing slack that could affect the take-up or release. Meanwhile, since the first take-up roller 110, the transmission cover 161, and the drive wheel 163 always rotate synchronously and in the same direction, and the tension transmitted by the torsion reset member 162 to the first take-up roller 110 is equal to the tension transmitted by the torsion reset member 162 to the transmission cover 161, the torsion reset member 162 will not be relatively torsioned during the rotation of the first take-up roller 110, the transmission cover 161, and the drive wheel 163, and will rotate synchronously and in the same direction with the first take-up roller 110, the transmission cover 161, and the drive wheel 163. This can prevent the torsion reset member 162 from fatigue failure due to frequent torsion and extend the service life of the torsion reset member 162.

[0074] The inner diameter of the cavity of the drive wheel 163 can be designed to a suitable size to facilitate the installation of the torsion reset member 162. For example, the inner diameter of the cavity can be designed to be greater than 12mm to facilitate the installation of at least a portion of the torsion reset member 162 in the cavity.

[0075] In actual installation, the sunshade 200 can be installed on the roller blind mechanism 100 without first rotating the drive wheel 163 to twist the torsion reset member 162 and accumulate elastic torsional force. By fixing the drive wheel 163, the elastic torsional force is not released. Then, the sunshade 200 is installed on the roller blind mechanism 100, that is, one side of the sunshade 200 is fixed to the annular winding belt 130, and the opposite side of the sunshade 200 is fixed to the pull member 170. Then, the drive wheel 163 is released, which releases the elastic torsional force accumulated by the torsion reset member 162, thereby causing the annular winding belt to... The pulling force of the 130 on the sunshade 200 is equal to the pulling force of the pulling member 170 on the sunshade 200, and the two pulling forces are in opposite directions, thus achieving force balance and making the sunshade 200 taut and tight, avoiding wrinkles or slack, and ensuring the rolling and releasing effect; at the same time, it also prevents the torsion reset member 162 from being relatively torsioned relative to the first winding wheel 110, transmission cover 161 and drive wheel 163, and rotates synchronously and in the same direction with the first winding wheel 110, transmission cover 161 and drive wheel 163, thereby avoiding fatigue failure of the torsion reset member 162 due to frequent torsion and extending the service life of the torsion reset member 162.

[0076] The connection between the slider 165 and the annular transmission belt 164 can be achieved directly through screwing, snap-fitting, or other methods, or it can involve intermediate connecting elements.

[0077] In one embodiment, the roller blind mechanism 100 further includes an adapter (not shown). The adapter is connected to the annular drive belt 164 by means of snap-fit ​​or screw-fit, and one end of the pulling member 170 and the slider 165 are also connected to the adapter by means of snap-fit ​​or screw-fit. In this way, the connection between the annular drive belt 164, the pulling member 170 and the slider 165 is realized through the adapter, so that the movement of the three can be carried out simultaneously, ensuring that the sunshade 200 can be rolled up or released.

[0078] The adapter can be in the form of an adapter block, an adapter plate, or an adapter frame.

[0079] like Figure 7 As shown, in one embodiment, the transmission assembly 160 includes a linear moving member (not shown), a fixing member 166, and a torsional energy storage member 167. The linear moving member is disposed opposite to the annular winding belt 130 and is capable of reciprocating along the direction of movement of the sunshade. The linear moving member is connected to the side of the sunshade 200 away from the annular winding belt 130 by means of screwing or bonding. Meanwhile, the fixing member 166 is spaced apart from the first winding wheel 110 along the axial direction of the spindle 150. The torsional energy storage member 167 is disposed between the fixing member 166 and the first winding wheel 110, and its opposite sides are connected to the fixing member 166 and the first winding wheel 110 respectively. Specifically, one side of the torsional energy storage member 167 is connected to the fixing member 166 by means of snap-fit ​​or screwing, and the other side of the torsional energy storage member 167 is connected to the first winding wheel 110 by means of snap-fit ​​or screwing. Thus, when the linear moving member moves along the direction in which the sunshade 200 covers the skylight to drive the sunshade 200 to cover the skylight, the sunshade 200 applies a pulling force to the annular transmission belt 164 under the action of the linear moving member. Under the action of the pulling force, the annular transmission belt 164 is synchronously driven to rotate along the direction in which the sunshade 200 covers the skylight, so that the annular transmission belt 164 releases the sunshade 200, and then synchronously drives the first winding wheel 110 to rotate, thereby causing the torsional energy storage member 167 to further twist relative to the fixed member 166 and accumulate torsional potential energy. When the linear moving member moves along the direction in which the sunshade 200 opens the skylight, the pulling force of the sunshade 200 on the annular transmission belt 164 disappears. At this time, the torsional potential energy accumulated by the torsional energy storage member 167 is released and reset, thereby driving the first winding wheel 110 to rotate in the opposite direction, and then driving the annular transmission belt 164 to rotate along the direction in which the sunshade 200 covers the open skylight, so that the annular transmission belt 164 rolls up the sunshade 200.

[0080] The linear moving component can be in the form of a pull rod or a pull strip. The reciprocating movement of the linear moving component along the moving direction of the sunshade 200 can be achieved by a linear motor drive or by a pull cable. It is only necessary to ensure that the linear moving component can reciprocate linearly along the moving direction of the sunshade 200 to drive the sunshade 200 to open or cover the skylight.

[0081] The fastener 166 can be in the form of a fixed seat, a fixed cover, etc. The fastener 166 can be connected to the spindle 150 or other external components by means of screwing or snapping, so that the fastener 166 can remain fixed or stationary relative to the first take-up wheel 110.

[0082] The torsional energy storage element 167 can be a torsion spring or other element capable of torsional energy storage and resetting.

[0083] like Figure 1 and Figure 8 As shown, the roller blind mechanism 100 also includes a mounting base 180. Both the first winding wheel 110 and the second winding wheel 120 are rotatably mounted on the mounting base 180. The mounting base 180 can then be used to install and support the first winding wheel 110 and the second winding wheel 120, ensuring their stable and reliable rotation. This, in turn, ensures that the annular winding belt 130 can operate stably and reliably to wind up or unwind the sunshade 200.

[0084] The first take-up reel 110 can be rotatably connected to the mounting base 180 via a mandrel 150, which can be fixed to the mounting base 180 by means of insertion or snap-fit. Similarly, the second take-up reel 120 can also be rotatably connected to the mounting base 180 via a mandrel 150, which can be fixed to the mounting base 180 by means of insertion or snap-fit.

[0085] It should be noted that "a certain body" or "a certain part" can be a portion of the corresponding "component," meaning that "a certain body" or "a certain part" is integrally formed and manufactured with the "other parts of the component"; or it can be an independent component that can be separated from the "other parts of the component," meaning that "a certain body" or "a certain part" can be manufactured independently and then combined with the "other parts of the component" to form a whole. The expression of "a certain body" or "a certain part" in this application is only one embodiment for ease of reading, and is not intended to limit the scope of protection of this application.

In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0089] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component. Furthermore, when a component is considered to be "fixed transmission connection" to another component, the two can be fixed in a detachable or non-detachable manner, as long as power transmission can be achieved, such as sleeve, snap-fit, integral molding, welding, etc., which can be achieved in the prior art and will not be elaborated here. When a component is perpendicular or approximately perpendicular to another component, it means that the two are ideally perpendicular, but due to the influence of manufacturing and assembly, there may be a certain degree of perpendicularity error.
