Description

Technical Field

[0001] This application relates to the field of sunshade technology for vehicle windows, and particularly to sunshade assemblies, glass assemblies, and vehicles. Background Technology

[0002] As consumers increasingly demand better sun protection from vehicles, many manufacturers equip their vehicles with sunshades. Generally, sunshades have extended and retracted states. When extended, the sunshade covers a large area of ​​the glass, effectively blocking sunlight. When retracted, the sunshade does not obstruct the glass and does not interfere with normal light transmission. The switching between extended and retracted states is primarily achieved through a drive mechanism.

[0003] In related technologies, the drive mechanism for driving a sunshade typically includes a carrier, a drive assembly, and a telescopic deployment component. Both the drive assembly and the telescopic deployment component are mounted on the carrier, and the drive assembly drives the telescopic deployment component to switch the sunshade between an extended and retracted state. Generally, the drive assembly is installed on the side of the telescopic deployment component, corresponding to the edge of the carrier.

[0004] However, the placement of the aforementioned drive components can cause the center of gravity of the carrier to shift, making the carrier prone to instability during installation and affecting the stability of the shading. Utility Model Content

[0005] Therefore, it is necessary to provide a sunshade assembly, glass assembly, and vehicle to address the issue of how to improve the installation stability of the sunshade assembly.

[0006] A sunshade assembly, the sunshade assembly comprising:

[0007] Load-bearing components and fork arm assemblies;

[0008] A drive assembly is movably connected to the carrier member; the drive assembly includes a transmission member and a drive member; the drive member is drively connected to the transmission member to drive the transmission member to move relative to the carrier member in a first direction; the transmission member is drively connected to the fork arm assembly such that when the transmission member moves in the first direction, the fork arm assembly moves relative to the carrier member in a second direction; the first direction and the second direction are intersecting.

[0009] A sunshade curtain is connected to the fork arm assembly, such that when the fork arm assembly extends in the second direction, it can extend the sunshade curtain, and when the fork arm assembly retracts in the second direction, it can retract the sunshade curtain; wherein...

[0010] The driving component is disposed at the middle of the carrier component along the first direction.

[0011] A glass assembly includes a glass body and a sunshade assembly as described in the above embodiments; the sunshade assembly is installed on the inner side of the glass body, and the sunshade curtain can be used to cover or expose the glass body when extended and retracted.

[0012] A vehicle includes a body body and a glass assembly as described in the above embodiments, the glass assembly being mounted on the body body.

[0013] The aforementioned sunshade assembly, glass assembly, and vehicle, with the drive component driving the transmission component to move in a first direction, enables the fork arm assembly to move in a second direction. Unlike a drive component directly driving the fork arm assembly in the second direction, the transmission component converts the motion in the first direction into movement of the fork arm assembly in the second direction. This reduces frictional loss between the transmission component and the fork arm assembly during same-direction movement, extends the service life of both the drive component and the fork arm assembly, and allows for smoother movement of the fork arm assembly in the second direction, avoiding potential vibrations or jamming caused by same-direction movement between the transmission component and the fork arm assembly. Furthermore, the drive component is positioned at the center of the load-bearing component, which helps maintain the center of gravity of the load-bearing component in this central location, thereby improving its stability and ensuring the stable movement of the sunshade assembly.

[0025] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are 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 this application. However, this application can be implemented 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 this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0026] See Figure 1 An embodiment of this application provides a glass assembly including a sunshade assembly 100 and a glass body.

[0027] Specifically, such as Figure 2 , Figure 3 and Figure 5As shown, the sunshade assembly 100 includes a fork arm assembly 110, a drive assembly 120, a sunshade curtain 130, and a support member 101. The drive member 122 may be integrated into the drive assembly 120, serving as one component of the drive assembly 120. In this case, the drive member 122 may be, but is not limited to, any of the following: a servo motor, a stepper motor, etc. The drive member 122 may also be manually driven, through user operation of rotating component 1221.

[0028] The drive assembly 120 is movably connected to the carrier 101. The drive assembly 120 includes a transmission member 121 and a drive member 122. The drive member 122 is driveably connected to the transmission member 121 to drive the transmission member 121 to move relative to the carrier 101 along a first direction X. The transmission member 121 is driveably connected to the fork arm assembly 110 such that when the transmission member 121 moves along the first direction X, the fork arm assembly 110 moves relative to the carrier 101 along a second direction Y. The first direction X and the second direction Y are intersecting.

[0029] The sunshade 130 is connected to the fork arm assembly 110, so that when the fork arm assembly 110 extends along the second direction Y, it can drive the sunshade 130 to extend, and when the fork arm assembly 110 retracts along the second direction Y, it can drive the sunshade 130 to retract.

[0030] When the sunshade 130 is extended, it can cover the glass body, ensuring that at least part of the glass body is covered. The portion of the glass body covered by the sunshade 130 provides a sunshade effect, reducing light intensity or ultraviolet radiation. Conversely, when the sunshade 130 is retracted, it exposes the glass body, allowing it to pass through normally and facilitating the view of passengers.

[0031] The driving component 122 is disposed at the center of the support component 101 along the first direction. It should be noted that the center of the support component 101 along the first direction X refers to the location of the central axis or center of gravity of the support component 101 along the first direction, and the position within a preset offset distance range from the central axis or center of gravity.

[0032] Thus, the driving component 122 drives the transmission component 121 to move along the first direction X, enabling the fork arm assembly 110 to move along the second direction Y. Unlike the driving component 122 directly driving the fork arm assembly 110 to move along the second direction Y, the transmission component 121 converts the movement in the first direction X into movement of the fork arm assembly 110 in the second direction Y. This reduces frictional loss between the driving component 122 and the fork arm assembly 110 during movement in the same direction, extending the service life of both components. It also allows for smoother movement of the fork arm assembly 110 in the second direction Y, avoiding potential vibrations or jamming caused by the transmission component 121 and the fork arm assembly 110 moving in the same direction. Furthermore, the driving component 122 is positioned at the center of the support component 101, which helps maintain the center of gravity of the support component 101 at its center, thereby improving the stability of the support component 101 and ensuring the stability of the sunshade assembly 100's movement.

[0033] It should be noted that the glass body can refer to any one of the following: the windshield, the rear windshield, the door glass, or the sunroof glass. In one example, the glass body in the above embodiment can refer to the windshield. In another example, the glass body in the above embodiment can refer to the rear windshield.

[0034] In one implementation scenario, the first direction X in the above embodiment can be the length direction of the glass body, and the second direction Y can be the width direction of the glass body. Further, the "third direction Z" mentioned below refers to a direction perpendicular to the first direction X and the second direction Y. In some implementation scenarios, the third direction Z can be the thickness direction of the glass body.

[0035] In some embodiments, the drive member 122 includes a rotating member 1221. The rotating member 1221 is rotatably disposed on the support member 101.

[0036] The rotating member 1221 is provided with a meshing part 120a. The transmission member 121 is provided with a meshing part 120b. The meshing part 120b and the meshing part 120a mesh, so that the meshing part 120b can reciprocate relative to the meshing part 120a in the first direction X, so that the rotating member 1221 drives the fork arm assembly 110 to move in the second direction Y through the transmission member 121.

[0037] It is understandable that by engaging the meshing part 120b on the fork arm assembly 110 and engaging the meshing part 120a on the rotating member 1221, there is no need to provide other power transmission components 121, such as timing belts or chains, between the rotating member 1221 and the fork arm assembly 110, thereby reducing the number of components in the drive assembly 120 and reducing the size of the drive assembly 120.

[0038] Furthermore, since the transmission between the transmission component 121 and the rotating component 1221 can be achieved without the use of synchronous belts and chains as in related technologies, the sunshade assembly 100 does not need to reserve space for the installation of annular transmission components such as synchronous belts and chains. Therefore, it is not necessary to reserve space for the interval when the annular transmission components 121 such as synchronous belts and chains are wound, which reduces the installation thickness of the drive component 120 and optimizes the integration performance of the sunshade assembly 100.

[0039] In addition, the meshing transmission method of the transmission component 121 and the rotating component 1221 is conducive to improving transmission accuracy and stability, and avoids the risk of slippage that occurs when using synchronous belts and chains.

[0040] It should be noted that the fork arm assembly 110 in the above embodiments may be, but is not limited to, an X-shaped structure, or a Y-shaped structure, etc., and no further limitations are made here.

[0041] In some embodiments, combined with Figures 1 to 3 As shown, the fork arm assembly 110 includes a first active fork arm 111 and a second active fork arm 112. The first active fork arm 111 and the second active fork arm 112 are intersecting and rotatably connected. At least one of the first active fork arm 111 and the second active fork arm 112 is rotatably connected to the transmission member 121.

[0042] For ease of explanation, the following description will be based on the movement process of the first active fork arm 111 in an implementation scenario.

[0043] When the drive member 122 rotates forward, the engaging part 120b engages with the engaging part 120a. At this time, the first active fork arm 111 can extend along the first direction X, so that the first active fork arm 111 rotates relative to the rotation fulcrum of the second active fork arm 112, and drives the second active fork arm 112 to rotate relative to the rotation fulcrum of the first active fork arm 111, so that the first active fork arm 111 and the second active fork arm 112 move towards each other in the first direction X. Correspondingly, the first active fork arm 111 and the second active fork arm 112 move from retraction to unfolding in the second direction Y, driving the sunshade curtain 130 to extend.

[0044] When the drive member 122 reverses, the engaging part 120b engages with the engaging part 120a, allowing the first active fork arm 111 to retract along the first direction X. At this time, the first active fork arm 111 rotates relative to the rotation fulcrum of the second active fork arm 112, and drives the second active fork arm 112 to rotate relative to the rotation fulcrum of the first active fork arm 111, thereby causing the first active fork arm 111 and the second active fork arm 112 to move away from each other in the first direction X. Correspondingly, the first active fork arm 111 and the second active fork arm 112 move from unfolding to retraction in the second direction Y, driving the retraction of the sunshade 130.

[0045] The rotatable connection between the first active fork arm 111 and the second active fork arm 112 means that the first active fork arm 111 can rotate relative to the second active fork arm 112. In one installation scenario, the fork arm assembly includes a first pin 113, through which the first active fork arm 111 is rotatably connected to the second active fork arm 112. The first pin 113 can be a stepped pin or a threaded pin, etc.

[0046] It should be noted that the first active fork arm 111 is rotatably connected to the second active fork arm 112 via the first pin 113. This means that the first pin 113 is inserted at the intersection of the first active fork arm 111 and the second active fork arm 112, and the first active fork arm 111 and the second active fork arm 112 can rotate with the first pin 113 as the pivot point, so that the first active fork arm 111 and the second active fork arm 112 can be rotatably connected relative to each other.

[0047] In another installation scenario, the first active fork arm 111 is inserted into the second active fork arm 112, allowing them to rotate relative to each other.

[0048] Furthermore, in one embodiment, such as Figure 3 as well as Figure 4 As shown, both the first active fork arm 111 and the second active fork arm 112 are rotatably connected to the transmission member 121. It can be understood that the rotatable connection of the first active fork arm 111 and the second active fork arm 112 to the transmission member 121 allows them to be synchronously subjected to the torque of the rotating member 1221, improving the consistency of their movements. This eliminates the uneven load caused by only the first active fork arm 111 or only the second active fork arm 112 being subjected to the torque of the rotating member 1221, resulting in smoother movement of the fork arm assembly 110 and preventing the sunshade 130 from tilting, thus ensuring the sunshade 130's coverage of the glass body.

[0049] It should be noted that when the rotating component 1221 is connected to the fork arm assembly 110 in a transmission manner, the fork arm assembly 110 has motion vectors in the first direction X and the second direction Y. In this process, it can be a motion process in which the rotating component 1221 drives the fork arm assembly 110 to rotate along the first direction X, so that the fork arm assembly 110 has a motion vector component in the second direction Y (at this time, the first direction X and the second direction Y are not set perpendicularly); it can also be a motion process in which the rotating component 1221 drives the fork arm assembly 110, and the fork arm assembly 110 converts the motion vector in the first direction X into the motion vector in the second direction Y.

[0050] In some implementations, see back Figure 3 as well as Figure 4 The transmission component 121 includes a transmission body 1211 and a moving body 1212. The transmission body 1211 has an engagement portion 120b. At least one of the first active fork arm 111 and the second active fork arm 112 is rotatably connected to the moving body 1212, and the moving body 1212 is rotatably connected to the transmission body 1211. The drive assembly 120 also includes a guide rail assembly 102. The guide rail assembly 102 is connected to the support member 101. At least a portion of the guide rail assembly 102 extends along a first direction X, and the moving body 1212 is slidably engaged with the guide rail assembly 102.

[0051] When the engaging part 120b and the engaging mating part 120a engage, the moving body 1212 moves along the first direction X to drive at least one of the first active fork arm 111 and the second active fork arm 112 to move along the second direction Y, thereby driving the fork arm assembly 110 to move along the second direction Y.

[0052] In this configuration, at least one of the first active fork arm 111 and the second active fork arm 112 is rotatably connected to the mobile body 1212 via a pin or a direct insertion mechanism. In one installation scenario, at least one of the first active fork arm 111 and the second active fork arm 112 further includes a second pin 1102. At least one of the first active fork arm 111 and the second active fork arm 112 is rotatably connected to the mobile body 1212 via the second pin 1102.

[0053] It is understandable that when the meshing part 120b and the meshing engagement part 120a are engaged, the transmission body 1211 can drive the moving body 1212 to move linearly relative to the driving member 122 in the first direction X. Then, the moving body 1212 can generate a certain thrust on at least one of the first active fork arm member 111 and the second active fork arm member 112. At this time, at least one of the first active fork arm member 111 and the second active fork arm member 112 uses the rotation fulcrum of the moving body 1212 relative to the transmission body 1211 as the fulcrum, and converts the horizontal thrust of the transmission body 1211 on the moving body 1212 in the first direction X into the moving power of at least one of the first active fork arm member 111 and the second active fork arm member 112 in the second direction Y, thereby driving the sunshade curtain 130 to switch between extension and retraction.

[0054] The switching between the extended and retracted states of the sunshade 130 depends on the horizontal thrust of the transmission body 1211 to at least one of the first active fork arm 111 and the second active fork arm 112 along the first direction X by the moving body 1212. The direction control of the horizontal thrust in the first direction X can be controlled by the forward and reverse rotation of the rotating member 1221.

[0055] Thus, at least one of the first active fork arm component 111 and the second active fork arm component 112 realizes that the horizontal thrust in the first direction X can be converted into the moving power of the fork arm assembly 110 in the second direction Y by moving the rotation fulcrum of the body 1212 relative to the transmission body 1211, thereby realizing the transmission of torque, reducing torque loss, improving transmission accuracy and transmission efficiency, and consequently making the drive component 120 drive the fork arm assembly 110 with less effort and reducing the load requirements on the drive component 122.

[0056] Furthermore, by setting the guide rail assembly 102, the activity stability of the moving body 1212 along the first direction X can be improved, which in turn helps to improve the rotation rate of the moving body 1212 in converting the thrust of the moving body 1212 in the first direction X into the extension thrust of the moving body 1212 driving the fork arm assembly 110 along the second direction Y. This improves the transmission accuracy and transmission efficiency of the sunshade assembly 100, and makes the extension and retraction process of the sunshade curtain 130 more stable, thus optimizing the user experience.

[0057] Optionally, in one embodiment, the first direction X and the second direction Y are arranged perpendicularly. Thus, by arranging the first direction X and the second direction Y perpendicularly, the conversion rate of the horizontal thrust of at least one of the first active fork arm member 111 and the second active fork arm member 112 in the first direction X into the moving power of the fork arm assembly 110 in the second direction Y is maximized. This improves the accuracy and efficiency of the transmission, making it easier for the drive assembly 120 to drive the fork arm assembly 110, and further reducing the load requirements of the drive assembly 122.

[0058] Specifically, the sliding fit structure between the guide rail assembly 102 and the moving body 1212 can be a fit between a sliding protrusion and a sliding recess, or a fit between a pulley and a slide rail, etc.

[0059] Accordingly, optionally, in one embodiment, such as Figure 5 as well as Figure 6 As shown, the drive assembly 120 includes two transmission members 121. A first active fork arm 111 and a second active fork arm 112 are rotatably connected to the two transmission members 121, respectively. The drive assembly 120 includes two opposing guide rail assemblies 102. One guide rail assembly 102 is slidably engaged with the moving body 1212 of the first active fork arm 111, and the other guide rail assembly 102 is slidably engaged with the moving body 1212 of the second active fork arm 112. This improves the deployment stability of the first active fork arm 111 and the second active fork arm 112, thereby enhancing the stability of the sunshade 130's extension and retraction processes.

[0060] It should be noted that the transmission component 121 in the above embodiments can be a movable rod, movable shaft, or other structure, and no further restrictions are imposed here.

[0061] Optionally, in one embodiment, the transmission member 121 includes a flexible shaft structure. A meshing portion 120b is disposed on the outer wall of the flexible shaft structure. In one example, the transmission body 1211 is a flexible shaft structure. Thus, by providing the meshing portion 120b on the flexible shaft structure, the structure is relatively simple and easy to manufacture. Furthermore, the flexible shaft structure can withstand a certain degree of deformation, thereby reducing the transmission stress between the transmission member 121 and the rotating member 1221, which helps to avoid deformation and damage to the transmission member 121 and the rotating member 1221, and improves the service life of the sunshade assembly 100. In addition, the flexible shaft structure can adapt to the curved surface of the glass body, which helps to reduce the gap between the drive assembly 120 and the glass body, thereby improving the coverage and fit between the sunshade curtain 130 and the glass body.

[0062] It should be noted that the rotating component 1221 in the above embodiments can be, but is not limited to, a worm gear, or a rotating gear, etc., without further restrictions.

[0063] In one embodiment, see back Figure 4 The drive assembly 120 includes two transmission members 121. A first active fork arm member 111 and a second active fork arm member 112 are rotatably connected to the two transmission members 121, and the first active fork arm member 111 and the second active fork arm member 112 are spaced apart from each other. The meshing part 120a is arranged along the circumferential direction of the rotating member 1221. That is, by setting up one rotating member 1221, the transmission of the fork arm assembly 110 by the two transmission members 121 is realized, which helps to save the installation space of the drive assembly 120, thereby facilitating the miniaturization of the sunshade assembly 100; at the same time, it helps to improve the synchronicity of the movement of the first active fork arm member 111 and the second active fork arm member 112, ensuring the consistency and stability of the movement of the sunshade assembly 100, and avoiding uneven force distribution.

[0064] At this time, the meshing structure between the meshing part 120b and the meshing mating part 120a can be a mating structure of the main thread and the auxiliary thread, or it can be a mating structure of the thread structure and the helical tooth structure when the worm is mated with the worm.

[0065] Specifically, in one example, the rotating component 1221 is a worm gear, and the transmission component 121 is a worm. A meshing portion 120a is disposed on the outer wall of the worm gear. A meshing portion 120b is disposed on the outer wall of the worm. The worm gear and the worm engage with each other through the meshing portions 120a. Specifically, the meshing portion 120b has a first tooth structure or a threaded structure, while the meshing portion 120a has a second tooth structure. The first tooth structure and the second tooth structure can be spur tooth structures or helical tooth structures, which can be selected according to different production scenarios, and no further restrictions are imposed here.

[0066] The meshing of the worm gear and worm through meshing parts 120a and 120b means that the first tooth structure or threaded structure can mesh with the second tooth structure to achieve meshing transmission between the worm gear and worm.

[0067] In one installation scenario, the worm gear is positioned between the worm of the first active fork arm 111 and the worm of the second active fork arm 112, and the worm gear is engaged with both the worm of the first active fork arm 111 and the worm of the second active fork arm 112.

[0068] In another example, the meshing part 120b is a first threaded part, and the meshing mating part 120a is a second threaded part. The first threaded part and the second threaded part are threadedly engaged. The transmission member 121 is a first threaded rod with a first threaded part, and the rotating member 1221 is a second threaded rod with a second threaded part. Thus, the threaded engagement of the first threaded part and the second threaded part enables relative movement between the transmission member 121 and the rotating member 1221, which helps to improve the accuracy and stability of the transmission.

[0069] In other embodiments, the first active fork arm 111 and the second active fork arm 112 are disposed opposite each other along a third direction Z, and at least the first active fork arm 111 and at least a portion of the second active fork arm 112 are disposed on the same plane. The third direction Z is perpendicular to the first direction X and the second direction Y. Thus, by reducing the stacking size of the drive assembly 120 in the second direction Y or the third direction Z, the integration performance of the sunshade assembly 100 is improved, which is beneficial for the miniaturization of the sunshade assembly 100. When the sunshade assembly 100 is being retracted, it does not affect the light transmittance performance of the glass body.

[0070] In one installation scenario, the first threaded rod of the first active fork arm 111, the first threaded rod of the second active fork arm 112, and the second threaded rod are all coplanar. Furthermore, the second threaded rod is threadedly connected to both the first threaded rod of the first active fork arm 111 and the first threaded rod of the second active fork arm 112.

[0071] Thus, by having the first threaded rod of the first active fork arm 111, the first threaded rod of the second active fork arm 112, and the second threaded rod coplanarly arranged, the first threaded rod and the second threaded rod can be coplanarly arranged in the third direction Z (the third direction Z is perpendicular to both the first direction X and the second direction Y), which can reduce the stacking size of the drive assembly 120 in the second direction Y; or, the first threaded rod and the second threaded rod can be coplanarly arranged in the second direction Y, which can reduce the stacking size of the drive assembly 120 in the third direction Z.

[0072] Of course, in addition to the meshing and engaging portion 120a in the above embodiment being arranged circumferentially around the rotating member 1221, the meshing and engaging portion 120a can also be arranged at intervals.

[0073] Specifically, in one example, both the transmission member 121 connected to the moving body 1212 corresponding to the first active fork arm 111 and the transmission member 121 connected to the moving body 1212 corresponding to the second active fork arm 112 are provided with engagement portions 120b, and the two transmission members 121 are spaced apart from each other. The rotating member 1221 is provided with two engagement portions 120a spaced apart. The engagement portions 120a and engagement portions 120b are provided in a one-to-one correspondence. At this time, the engagement portion 120b can be a first tooth structure. The engagement portion 120a can be a second tooth structure, and the first tooth structure and the second tooth structure mesh with each other.

[0074] In this way, by setting the length of the first tooth structure and the second tooth structure, the meshing distance between the meshing part 120b and the meshing mating part 120a can be controlled, thereby controlling the movement distance of the moving body 1212 driven by the transmission member 121 relative to the rotating member 1221, and thus achieving precise control of the extension degree of the sunshade curtain 130.

[0075] Furthermore, the two meshing parts 120a are arranged opposite to each other, and the line connecting the two meshing parts 120a passes through the rotation axis of the rotating member 1221. Thus, the opposite arrangement of the two meshing parts 120a ensures that when the meshing parts 120b and 120a are engaged, the rotating member 1221 can maintain a force balance, reducing the stress between the rotating member 1221 and the transmission member 121, thereby improving the motion stability of the sunshade assembly 100 and achieving smooth extension and retraction of the sunshade curtain 130.

[0076] In some embodiments, see back Figure 1 as well as Figure 6 The fork arm assembly 110 also includes a first driven fork arm 114 and a second driven fork arm 115. The first driven fork arm 114 and the second driven fork arm 115 are each provided with a first end 110a and a second end 110b along their own length direction.

[0077] The first end 110a of the first driven fork arm 114 is rotatably connected to the end of the first driving fork arm 111 located away from the engagement portion 120b. The first end 110a of the second driven fork arm 115 is rotatably connected to the end of the second driving fork arm 112 located away from the engagement portion 120b. The second end 110b of the first driven fork arm 114 is connected to the sunshade 130. The second end 110b of the second driven fork arm 115 is connected to the sunshade 130.

[0078] The implementation method of the rotary connection can be referred to the explanation in the above embodiments, and will not be elaborated further here.

[0079] Specifically, in one installation scenario, the fork arm assembly 110 further includes a third pin 116. The third pin 116 is inserted into the overlapping area between the first end 110a of the first driven fork arm 114 and the first driven fork arm 111, and the first end 110a and the first driven fork arm 111 can rotate relative to the third pin 116, so that the first end 110a of the first driven fork arm 114 is rotatably connected to the first driven fork arm 111 through the third pin 116.

[0080] Correspondingly, in another installation scenario, the fork arm assembly 110 also includes a fourth pin 117. The fourth pin 117 is inserted into the overlapping area between the first end 110a of the second driven fork arm 115 and the second driven fork arm 112, and the first end 110a and the second driven fork arm 112 can rotate relative to the fourth pin 117, so that the first end 110a of the second driven fork arm 115 is rotatably connected to the second driven fork arm 112 through the fourth pin 117.

[0081] It is understandable that by setting the first driven fork arm 114 and the second driven fork arm 115, the movement distance of the fork arm assembly 110 in the second direction Y can be increased, thereby increasing the deployment range of the sunshade 130 and satisfying the large-area sunshade performance.

[0082] Furthermore, in one embodiment, see back Figure 1 as well as Figure 6 The length of the first driven fork arm 114 is less than the length of the first driven fork arm 111. This shorter length ensures that the torque of the fork arm assembly 110 is not excessive, thus reducing the driving force requirement of the rotating member 1221 on the first driven fork arm 111, and consequently reducing the load on the rotating member 1221 from the driving member 1221. Furthermore, it prevents the excessively long first driven fork arm 114 from increasing its length in the first direction X when the fork arm assembly 110 is retracted, thereby ensuring that the size of the driving assembly 120 in the first direction X is not excessive, which is beneficial for the miniaturization of the sunshade assembly 100.

[0083] Similarly, in yet another embodiment, see back Figure 1 as well as Figure 6 The length of the second driven fork arm 115 is less than the length of the second driven fork arm 112. Accordingly, the shorter length of the second driven fork arm 115 compared to the second driven fork arm 112 ensures that the torque of the fork arm assembly 110 is not too large, thereby reducing the driving force requirement of the rotating member 1221 on the second driven fork arm 112 and thus reducing the load required for the rotating member 1221 to rotate. On the other hand, it avoids the excessive length of the second driven fork arm 115 from increasing the length dimension in the first direction X when the fork arm assembly 110 is retracted, thus ensuring that the size of the drive assembly 120 in the first direction X is not too large, which is beneficial to the miniaturization of the sunshade assembly 100.

[0084] Alternatively, in some embodiments, see back Figure 1 The first active fork arm 111 and the second active fork arm 112 are of equal length. The first driven fork arm 114 and the second driven fork arm 115 are of equal length. Thus, the equal length of the first active fork arm 111 and the second active fork arm 112 ensures that the torques generated by them during driving are balanced. Similarly, the equal length of the first driven fork arm 114 and the second driven fork arm 115 ensures that the torques generated by them during driving are balanced, reducing unnecessary stress concentration and improving the overall stability of the sunshade assembly 100.

[0085] In some of these embodiments, when the fork arm assembly 110 is in motion, the first active fork arm 111 remains in a straight line and the second active fork arm 112 remains in a straight line.

[0086] Thus, when the fork arm assembly 110 is fully retracted, the first active fork arm 111 and the second active fork arm 112 can overlap on the same height plane, and the overlap thickness of the first active fork arm 111 and the second active fork arm 112 in the second direction Y is related to the one with the largest thickness in the second direction Y of the first active fork arm 111 and the second active fork arm 112. This helps to reduce the size occupied by the fork arm assembly 110 in the second direction Y when retracted, thereby improving the integration performance of the sunshade assembly 100 and avoiding the impact of the sunshade assembly 100 on the light transmission performance of the glass body when retracted.

[0087] In any embodiment of the drive assembly 120 described above, the sunshade assembly 100 includes two spaced-apart fork arm assemblies 110. The drive assembly 120 includes two transmission members 121. The engaging parts 120a and the two corresponding engaging parts 120b of the two transmission members 121 are all engaged. That is, the drive assembly 120 can realize the movement of the two fork arm assemblies 110, thereby reducing the number of drive assemblies 120, reducing the size of the sunshade assembly 100, and thus contributing to the miniaturization of the sunshade assembly 100.

[0088] Furthermore, in one embodiment, the drive member 122 is disposed between the two fork arm assemblies 110. Thus, by disposing the drive member 122 between the two fork arm assemblies 110, the drive member 122 can simultaneously drive both fork arm assemblies 110 via the rotating member 1221, reducing the number of drive assemblies 120. This improves the integration performance of the sunshade assembly 100 and ensures that the sunshade assembly 100 maintains its center of gravity balance, thereby enhancing the installation stability of the sunshade assembly 100.

[0089] Furthermore, the drive assembly 120 is positioned between the two fork arm assemblies 110, which reduces the length of the transmission member 121, thereby further optimizing the dimensions in the first direction X and facilitating the miniaturization of the sunshade assembly 100. In one example, the drive member 122 is centrally positioned between the two fork arm assemblies 110, allowing the two fork arm assemblies 110 to be configured identically, and the length of the transmission member 121 to remain consistent. This reduces the design difficulty when the lengths of the two fork arm assemblies 110 are different, and improves manufacturing efficiency.

[0090] Furthermore, in one embodiment, such as Figure 1 as well as Figure 5 As shown, the two first active fork arms 111 are connected to the two corresponding transmission components 121.

[0091] In this way, other components can be installed using the transmission component 121 as the installation reference, which helps to improve installation accuracy and efficiency.

[0092] In another embodiment, such as Figure 1 as well as Figure 5 As shown, the two transmission components 121, which are arranged in a one-to-one correspondence between the two fork arm assemblies 110, are integrally formed.

[0093] In this way, there is no need to produce the transmission component 121 separately multiple times, which reduces the processing difficulty of the two transmission components 121 and helps to improve installation accuracy and efficiency.

[0094] To further improve the integration performance of the sunshade assembly 100, in some embodiments, combined with Figure 1 as well as Figure 7 As shown, the sunshade 130 has a first side 131 and a second side 132 opposite to each other along the second direction Y. The second side 132 is connected to the fork arm assembly 110. The sunshade assembly 100 also includes a winding member 140, and the first side 131 is used to wind into the winding member 140.

[0095] In this way, the first side 131 can be wound together with the winding member 140 to allow the sunshade 130 to be rolled up in the winding member 140 when it is retracted, avoiding the messy arrangement of the sunshade 130 on the glass body and ensuring that the sunshade assembly 100 does not affect the light transmission performance of the glass body when the fork arm assembly 110 is retracted.

[0096] In other embodiments, see back Figure 7 The sunshade assembly 100 also includes a pull rod 150. The pull rod 150 includes a first body 151 and a second body 152. The first body 151 and the second body 152 are connected together. The first body 151 is connected to the fork arm assembly 110. The second side 132 is connected to the second body 152. The connection method between the second side 132 and the second body 152 can be, but is not limited to, a non-removable connection method such as adhesive bonding, or a detachable connection method such as snap-fit ​​or magnetic connection.

[0097] Thus, by connecting the first body 151 to the fork arm assembly 110 and the second side 132 to the second body 152, the second side 132 is connected to the fork arm assembly 110 via the tie rod 150. This increases the area of ​​the second body 152, thereby increasing the connection area between the sunshade 130 and the fork arm assembly 110 and improving the installation stability of the sunshade 130.

[0098] Furthermore, in one embodiment, see back Figure 1The sunshade 130 includes two pull rods 150 and two fork arm assemblies 110. The two fork arm assemblies 110 are correspondingly arranged with the two pull rods 150, and the pull rods 150 are connected between the fork arm assemblies 110 and the side of the sunshade 130 away from the drive assembly 120. The two fork arm assemblies 110 and the two pull rods 150 are adjacent and spaced apart along a first direction X. The sunshade 130 has a recess 1301, which is located between the two fork arm assemblies 110.

[0099] Understandably, the recess 1301 can be used to limit the movement of the vehicle's rearview mirror, etc., thereby preventing the sunshade 130 from covering the rearview mirror, etc. The recess 1301 is located between the first body 151 and the second body 152, and a portion of the recess 1301 will not cause positional interference to the rearview mirror, etc. Neither the first body 151 nor the second body 152 will cause impact to the rearview mirror, etc. within the recess 1301, thereby ensuring the structural stability of the rearview mirror, etc.

[0100] In some embodiments, such as Figure 8 As shown, at least one of the first active fork arm 111 and the second active fork arm 112 includes a fork arm body 1101. The fork arm body 1101 includes a first connecting portion 1101a, a second connecting portion 1101b, and a third connecting portion 1101c. The first connecting portion 1101a is used to connect with the movable body 1212. The second connecting portion 1101b is used for a transmission connection with the sunshade 130. The first connecting portion 1101a and the second connecting portion 1101b are spaced apart, and the third connecting portion 1101c is connected between the first connecting portion 1101a and the second connecting portion 1101b.

[0101] Thus, the third connecting part 1101c increases the lever arm of the fork body 1101, thereby making the transmission of the transmission member 121 to the fork body 1101 more effortless and reducing the load requirements on the drive member 122.

[0102] It should be noted that the extension lines of the first connecting part 1101a and the second connecting part 1101b can be either collinear or non-collinear.

[0103] Furthermore, in one embodiment, the extension line of the third connecting portion 1101c is inclined to the extension lines of the first connecting portion 1101a and the second connecting portion 1101b, so that the first connecting portion 1101a and the second connecting portion 1101b are not collinear. The first pin 113 is rotatably mounted on the third connecting portion 1101c.

[0104] Thus, the third connecting part 1101c, the first connecting part 1101a, the second connecting part 1101b, and the second connecting part 1101b are not collinear. The extension line of the third connecting part 1101c is inclined to the extension lines of the first connecting part 1101a and the second connecting part 1101b, so that the third connecting part 1101c, the first connecting part 1101a, and the second connecting part 1101b are bent, which helps to improve the structural strength of the fork arm body 1101 and thereby improve the movement stability of the sunshade assembly 100.

[0105] Alternatively, in one embodiment, see back Figure 8 The first connecting portion 1101a and the second connecting portion 1101b are arranged in parallel. This parallel arrangement ensures that the lever arm direction of the fork arm body 1101 is consistent with that of the first connecting portion 1101a and the second connecting portion 1101b, avoiding the generation of lever arms in other directions. This improves the motion conversion rate of the fork arm body 1101 and optimizes the transmission efficiency and accuracy of the drive assembly 120.

[0106] In yet another embodiment, see back Figure 8 The third connecting part 1101c, the first connecting part 1101a, and the second connecting part 1101b are all vertically arranged. In this way, the first connecting part 1101a and the second connecting part 1101b are symmetrically arranged with respect to the third connecting part 1101c, thereby making the force on the fork body 1101 uniform, improving the activity stability of the fork body 1101, and thus improving the movement stability of the fork assembly 110.

[0107] In another embodiment, such as Figure 9 As shown, the pull rod 150 is rotatably connected to the fork arm assembly 110. Thus, when the fork arm assembly 110 is retracted, relative rotation can also occur between the pull rod 150 and the fork arm assembly 110, thereby realizing the folding of the pull rod 150, further reducing the space occupied by the sunshade assembly 100 in the second direction, and optimizing the integration performance of the sunshade assembly 100.

[0108] Specifically, in one example, the sunshade assembly also includes a fifth pin 160. The tie rod 150 is rotatably connected to the fork arm assembly 110 via the fifth pin 160.

[0109] According to a second aspect of this application, this application also provides a vehicle, including a glass assembly and a vehicle body. The glass assembly is mounted on the vehicle body. Thus, the arrangement of the sunshade assembly 100 optimizes the vehicle's sunshade performance without causing excessive space occupation, thereby improving the user experience.

[0110] In one embodiment, the second body 152 is provided with a locking part, which is used to detachably connect with a locking engagement part provided on the vehicle body. When the locking part and the locking engagement part are connected, the sunshade 130 is fixed relative to the vehicle body. The engagement method of the locking part and the locking engagement part can be, but is not limited to, snap-fit, magnetic connection, etc., and is not limited in detail here.

[0111] Thus, the locking part on the second body is detachably connected to the locking engagement part on the vehicle body, so that the sunshade assembly 100 can be quickly fixed to the vehicle body when extended, ensuring the installation stability of the sunshade 130 on the vehicle body, thereby ensuring the stable sunshade performance of the sunshade 130.

[0112] The terms "first" and "second" appearing above are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0113] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
