Description
Technical Field
[0001] This application relates to the technical field of automotive sunshades, and in particular to a sunshade assembly, a glass assembly, and a vehicle. Background Technology
[0002] With social development and improved living standards, automobiles have become an indispensable means of transportation in people's daily lives and work. While bringing convenience to people's travel, automobiles also encounter some new problems during use. For example, in the hot summer, strong sunlight directly shining into the car will cause the interior temperature to rise rapidly, not only reducing passenger comfort but also accelerating the aging of electronic components and interior fabrics. To address this, sunroofs and door windows can often use sunshade solutions with dimming modules to block or reduce light entering the car. However, due to its special installation position, the windshield cannot replicate the sunroof's design, making windshield sunshades a more viable option in the market.
[0003] The windshield sunshade mainly consists of a drive module and a roller sunshade. The drive module is connected to the roller sunshade and extends or retracts the curtain to block light from the windshield and retract it. However, existing drive modules are complex in structure and large in size, occupying more interior space during installation. They are also prone to interfering with existing structural components in the vehicle and can generate abnormal noises, affecting the user experience. Therefore, they have significant limitations in applicability. Summary of the Invention
[0004] Therefore, it is necessary to provide a sunshade assembly, glass assembly, and vehicle to address the issues of complex structure, large installation space occupation, impact on user experience, and limited applicability.
[0005] A first aspect of this application provides a sunshade assembly comprising:
[0006] Mounting base;
[0007] A transmission mechanism, which is movably disposed on the mounting base;
[0008] A drive source is mounted on the mounting base and arranged on one side of the transmission mechanism along a first direction of the sunshade assembly; the drive source is connected to the transmission mechanism in a driving connection.
[0009] A telescopic mechanism, which is connected to the transmission mechanism, wherein the transmission mechanism is capable of driving the telescopic mechanism to extend or retract along a second direction of the sunshade assembly, the second direction intersecting the first direction; and
[0010] A sunshade curtain, which is connected to the telescopic mechanism and can be extended or retracted in response to the telescopic mechanism.
[0011] This solution's sunshade assembly is installed on the vehicle and works in conjunction with the glass, providing sunshade capabilities by blocking the glass. Specifically, the mounting bracket integrates the transmission mechanism, drive source, telescopic mechanism, and sunshade into a single, elongated structure. This results in a compact overall layout, small size, and minimal installation space occupation. When installed in different vehicle models, it has minimal interference and impact on existing structures around the installation location, thus offering greater and more flexible applicability. In the initial state, the telescopic mechanism remains in the retracted position, while the sunshade is in the retracted position. When sunlight shines on the glass, the drive source is activated, which drives the transmission mechanism. The transmission mechanism then drives the telescopic mechanism to extend from its retracted state along the second direction of the sunshade assembly, thereby causing the sunshade to unfold and block the surface of the glass, thus preventing sunlight from passing through the glass and entering the vehicle. When the sunshade is removed, the drive source outputs a reverse driving force, causing the telescopic mechanism to retract and the sunshade to retract, revealing the glass again. This does not affect the normal use of the vehicle. The transmission mechanism and telescopic mechanism have a simple structure, reliable and effective transmission, and avoid generating abnormal noises that would affect the user experience.

[0045] 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.
[0046] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0047] Furthermore, where the terms "first" and "second" appear, these terms 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. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0048] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," 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 expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0049] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0050] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.
[0051] This application provides a vehicle, which can be any type of vehicle in the prior art, such as a sedan, SUV, pickup truck, etc., and can be flexibly selected according to actual needs.
[0052] A vehicle consists of at least a body and a glass assembly, with the glass assembly mounted on the body. As is easily understood, the glass assembly is mounted at the front of the vehicle body, specifically on the front side of the driver's compartment, and serves to block the oncoming wind while the vehicle is in motion.
[0053] Optionally, the glass assembly can be any one of, but not limited to, a windshield assembly, a rear windshield assembly, and a panoramic sunroof assembly. For example, in this application, the glass assembly is a windshield assembly.
[0054] In one embodiment, the glass assembly includes glass and a sunshade assembly 100, which is mounted on the inside of the glass, and the sunshade curtain 50 can completely block or expose the glass.
[0055] As is easily understood, the sunshade 50 has an extended state and a retracted state. When the sunshade 50 is in the extended state, it completely blocks the glass; when the sunshade 50 is in the retracted state, it exposes the glass.
[0056] For example, the sunshade assembly 100 is located inside the cockpit and can be installed in any location inside the vehicle, such as above, inside, or below the center console. The specific location can be flexibly selected according to actual needs.
[0057] When the sunshade 50 completely reveals the glass, it will not obstruct the glass, thus not affecting the driver's or passengers' visibility and ensuring driving safety. When the sunshade 50 completely blocks the glass, sunlight will not be able to enter the vehicle through the glass, avoiding discomfort to the driver and passengers inside the vehicle, as well as aging and damage to the vehicle's fabrics, electrical components, etc.
[0058] See Figures 1 to 3 The present application illustrates a sunshade assembly 100, which includes a mounting base 10, a transmission mechanism 20, a drive source 30, a telescopic mechanism 40, and a sunshade curtain 50.
[0059] The transmission mechanism 20 is movably mounted on the mounting base 10, and the drive source 30 is mounted on the mounting base 10. The drive source 30 is arranged on one side of the transmission mechanism 20 along the first direction of the sunshade assembly 100, and the drive source 30 is connected to the transmission mechanism 20 in a transmission connection. The telescopic mechanism 40 is connected to the transmission mechanism 20 in a transmission connection. The transmission mechanism 20 can drive the telescopic mechanism 40 to extend or retract along the second direction of the sunshade assembly 100. The second direction intersects with the first direction. The sunshade curtain 50 is connected to the telescopic mechanism 40 and can be extended or retracted in response to the extension or retraction of the telescopic mechanism 40.
[0060] For example, using the glass and vehicle body in their installed state as a reference frame, the first direction of the sunshade assembly 100 is specifically... Figure 1 and Figure 2 The X-axis direction in the text can be understood as the width direction of the vehicle body (left and right) or the length direction of the glass in the horizontal direction. The second direction of the sunshade assembly 100 is specifically... Figure 1 and Figure 2 The Y-axis direction can be understood as the height direction of the vehicle body or the width direction of the glass in the vertical direction.
[0061] In other words, the sunshade 50 uses a lifting motion to block or reveal the glass.
[0062] Specifically, the transmission mechanism 20 in this application includes a transmission wheel set, a transmission component 23, and a transmission block 24. The transmission wheel set is rotatably mounted on the mounting base 10, the transmission component 23 is mounted around the outside of the transmission wheel set, and the transmission block 24 is connected to the transmission component 23 in a transmission manner. The drive source 30 is connected to the transmission wheel set in a transmission manner, and the telescopic mechanism 40 is connected to the transmission block 24 in a transmission manner. The transmission block 24 can drive the telescopic mechanism 40 to extend or retract along the second direction of the sunshade assembly 100.
[0063] In summary, implementing the technical solution of this embodiment will achieve the following beneficial effects: The sunshade assembly 100 of this solution is installed on the vehicle and works in conjunction with the glass, enabling the glass to have sunshade capabilities by blocking the glass; specifically, the mounting base 10 integrates the transmission mechanism 20, drive source 30, telescopic mechanism 40, and sunshade curtain 50 into one unit, forming a flat and elongated structure, making the overall structure of the sunshade assembly 100 compact, small in size, and occupying less installation space. When equipped in vehicles of different models, it has little interference and impact on the existing mechanisms around the installation location, thus possessing higher and more flexible applicability; in the initial state, the telescopic mechanism 40 remains in the retracted state while the sunshade curtain 50 is in the retracted position. When sunlight shines on the glass... The drive source 30 is activated, which drives the transmission wheel set to rotate. The transmission wheel set drives the transmission component 23 to move, which in turn drives the transmission block 24 to move synchronously. The transmission block 24 ultimately drives the telescopic mechanism 40 to extend from the retracted state along the second direction of the sunshade assembly 100, thereby causing the sunshade curtain 50 to unfold and cover the surface of the glass, achieving the purpose of blocking sunlight from passing through the glass and entering the vehicle. When the sunshade ends, the drive source 30 is controlled to output a reverse driving force, which drives the telescopic mechanism 40 to retract and the sunshade curtain 50 to retract, and the sunshade curtain 50 re-exposes the glass, without affecting the normal use of the vehicle. The transmission mechanism 20 and the telescopic mechanism 40 have simple structures, reliable and effective transmission, and avoid abnormal noise that would affect the user experience.
[0064] Please continue reading. Figure 1 , Figure 2 , Figure 4 and Figure 5 In one embodiment, the mounting base 10 includes a first support 11 and a second support 12. The first support 11 and the second support 12 can be a separate structure or connected into an integral structure through an intermediate connector, depending on the actual needs.
[0065] The first support 11 and the second support 12 are arranged at intervals along the first direction of the sunshade assembly 100. The drive source 30 is disposed on the first support 11. The transmission wheel set includes a driving wheel 21 and a driven wheel 22. The driving wheel 21 is rotatably disposed on the first support 11 and connected to the drive source 30. The driven wheel 22 is rotatably disposed on the second support 12. The transmission component 23 is wrapped around the outside of the driving wheel 21 and the driven wheel 22. One end of the sunshade curtain 50 is connected to the first support 11, and the other end of the sunshade curtain 50 is connected to the second support 12.
[0066] Compared to the existing technology where the drive source 30 is installed in the middle of the transmission mechanism 20 and the sunshade 50, this solution arranges the drive source 30 on one side of the sunshade 50 and connects it to the transmission wheel set. This avoids encroaching on the core space in the middle of the vehicle interior, and makes full use of the space in the side area of the vehicle body. Furthermore, the drive source 30 and the transmission mechanism 20 form a flat and long installation structure, which reduces the requirements for installation space.
[0067] During operation, the drive source 30 drives the drive wheel 21 to rotate, which in turn drives the transmission component 23 and the driven wheel 22 to rotate. The power output is smooth and the response speed is fast. The structure is simple and helps to avoid abnormal noise. The two ends of the sunshade curtain 50 are fixed on the first support 11 and the second support 12 respectively. The installation structure is simple and has good stability.
[0068] Specifically, in one optional embodiment, the driving pulley 21 includes a first synchronous pulley, the driven pulley 22 includes a second synchronous pulley, and the transmission component 23 includes a synchronous belt, which is engaged and wound around the outside of the first and second synchronous pulleys. That is, in this case, the transmission mechanism 20 constitutes a synchronous belt transmission mechanism 20.
[0069] Alternatively, as an alternative to the above embodiments, in another optional embodiment, the driving wheel 21 includes a first sprocket, the driven wheel 22 includes a second sprocket, and the transmission member 23 includes a transmission chain, which is meshed and wound around the outside of the first sprocket and the second sprocket. That is, in this case, the transmission mechanism 20 constitutes a sprocket transmission mechanism 20.
[0070] The aforementioned synchronous belt drive mechanism 20 or sprocket drive mechanism 20, through the meshing transmission relationship of the meshing teeth, can avoid slippage, help ensure transmission efficiency and stability, prevent abnormal noise, and facilitate subsequent maintenance and repair at a low cost.
[0071] Please continue reading. Figure 2 and Figure 3 Based on any of the above embodiments, the transmission member 23 includes a first transmission part 231 and a second transmission part 232, which are arranged opposite to each other along a second direction of the sunshade assembly 100. More specifically, the line connecting the center of the driving wheel 21 and the center of the driven wheel 22 is set as a dividing line, and the first transmission part 231 and the second transmission part 232 are located on opposite sides of the dividing line.
[0072] The transmission block 24 includes a first slider 241 and a second slider 242. The first slider 241 is disposed in the first transmission part 231, and the second slider 242 is disposed in the second transmission part 232. The first slider 241 and the second slider 242 can move closer to or further away from each other.
[0073] The telescopic mechanism 40 is connected to the first slider 241 and the second slider 242 in a transmission connection.
[0074] In this application, the telescopic mechanism 40 includes, but is not limited to, organ mechanisms, screw mechanisms, scissor mechanisms, etc. For ease of understanding, the following description uses a scissor mechanism as an example of the telescopic mechanism 40.
[0075] Combination Figure 2 and Figure 3 As shown, for example, when the transmission component 23 is driven to rotate counterclockwise, the first slider 241 mounted on the first transmission part 231 and the second slider 242 mounted on the second transmission part 232 slide towards each other. The first slider 241 and the second slider 242 then output a pushing force to the scissor mechanism, causing the scissor mechanism to extend, thereby driving the sunshade 50 to unfold and block the glass. Conversely, when the transmission component 23 rotates clockwise, the first slider 241 and the second slider 242 slide away from each other, outputting a pulling force to the scissor mechanism, causing the scissor mechanism to retract, thereby driving the sunshade 50 to retract and reveal the glass again. This drive scheme, formed by the first slider 241, the second slider 242, and the scissor mechanism, eliminates the need for guide rails or other components on the sunshade 50. The driving method for the sunshade 50 is simple and efficient, requiring minimal modification to existing vehicle components, making installation and use more flexible and applicable to a wide range of vehicle models.
[0076] In order to guide the reciprocating sliding of the first slider 241 and the second slider 242, thereby improving the reliability and smoothness of the transmission of the scissor mechanism by the first slider 241 and the second slider 242, the transmission mechanism 20 also includes a slide rail 25. One end of the slide rail 25 is set on the first support 11, and the other end of the slide rail 25 is set on the second support 12. The first slider 241 and the second slider 242 can be slidably mounted on the slide rail 25.
[0077] For example, the slide rail 25 is a channel steel strip component made of aluminum material, which is installed and fixed to the first support 11 and the second support 12 by at least one of the following methods: screwing, snap-fitting, riveting, etc. The structure is simple and the weight is light, which is conducive to the lightweight design of the sunshade assembly 100 and the vehicle.
[0078] Please continue reading. Figure 4 Furthermore, the transmission mechanism 20 also includes a guide block 26, which is disposed at the end where the slide rail 25 is installed and the first support 11. The guide block 26 guides and cooperates with the transmission component 23. On the one hand, the guide block 26 slides and cooperates with the transmission component 23, which guides and limits the transmission component 23 and ensures the smooth rotation of the transmission component 23. On the other hand, the guide block 26 also presses against the transmission component 23 to achieve a certain tensioning effect, preventing the transmission component 23 from deforming and elongating and easily falling off the driving wheel 21 and the driven wheel 22, which would affect the reliability of the transmission mechanism 20.
[0079] It is worth noting that the part of the guide block 26 that contacts the transmission component 23 has a smooth structure (e.g., a convex arc surface), which helps to reduce wear on the transmission component 23 and improve the service life of the transmission component 23.
[0080] Please continue reading. Figure 2 In one embodiment, the scissor lift mechanism includes a first active fork arm 41, a second active fork arm 42, a first driven fork arm 43, a second driven fork arm 44, a first pin 45, a second pin 46, and a third pin 47. The first active fork arm 41 is rotatably connected to the second active fork arm 42 via the first pin 45. One end of the first active fork arm 41 is rotatably connected to the first slider 241. The other end of the first active fork arm 41 is rotatably connected to one end of the first driven fork arm 43 via the second pin 46. One end of the second active fork arm 42 is rotatably connected to the second slider 242. The other end of the second active fork arm 42 is rotatably connected to one end of the second driven fork arm 44 via the third pin 47.
[0081] Please continue reading. Figure 1 The sunshade curtain 50 includes a roller shutter 51, a curtain fabric 52, and a support rod 53. The roller shutter 51 is mounted on the mounting base 10. One side of the curtain fabric 52 is rolled up and mounted on the roller shutter 51. The curtain fabric 52 can be unfolded or retracted relative to the roller shutter 51. The other side of the curtain fabric 52 is connected to the support rod 53. The support rod 53 is connected to the other end of the first driven fork arm 43 and the other end of the second driven fork arm 44.
[0082] During operation, when the first slider 241 and the second slider 242 slide close together, the first active fork arm 41 and the second active fork arm 42, as well as the first driven fork arm 43 and the second driven fork arm 44, rotate and move closer to each other, causing the length of the scissor mechanism along the second direction to increase, which pushes the support rod 53 and the curtain 52, so that the curtain 52 extends and unfolds relative to the roller shutter 51 to block the glass; when the first slider 241 and the second slider 242 slide away from each other, the curtain 52 is rolled up into the inside of the roller shutter 51, realizing the retraction of the curtain 52 and revealing the glass.
[0083] Furthermore, a spring shaft (not shown in the figure) is installed inside the roller shutter cylinder 51, and one side of the curtain 52 is wound and connected to the spring shaft. When the curtain 52 is stretched and unfolded, the torsion spring shaft accumulates elastic torque; when the curtain 52 needs to be retracted, the scissor mechanism drives the support rod 53 to return, and the torsion spring shaft automatically rotates to apply elastic tension to the curtain 52, thereby realizing automatic winding of the curtain 52 and ensuring that the curtain 52 is better and more smoothly retracted into the roller shutter cylinder 51.
[0084] For example, the coil spring shaft is specifically composed of a rotatable coil and a torsion spring assembly mounted on at least one end of the coil.
[0085] Preferably, considering that the area of the curtain 52 is usually large, the size of a single scissor mechanism needs to be large, which affects the installation and the stability of a single scissor mechanism is also slightly poor, therefore, based on any of the above embodiments, two transmission blocks 24, scissor mechanisms and support rods 53 are provided and assembled in a one-to-one correspondence. The two support rods 53 and the two scissor mechanisms are arranged side by side at intervals along the first direction of the sunshade assembly 100.
[0086] It is easy to understand that when the transmission component 23 rotates, it drives the two sets of first sliders 241 and second sliders 242 to move synchronously. Therefore, it can ensure the synchronous movement of the two sets of scissor mechanisms and support rods 53, and ensure that the curtain 52 can be unfolded or retracted in a flat structure, improving the user experience. At the same time, it also helps to ensure that the unfolded curtain 52 does not become skewed and can completely block the glass, preventing light leakage.
[0087] Please continue reading. Figure 1 A rearview mirror is typically installed on the top of the inner side of the glass. In one embodiment, a notch 521 is provided on the side of the curtain 52 away from the roller shutter 51, and the notch 521 is arranged between two support rods 53. When the curtain 52 is unfolded, the bracket of the rearview mirror extends into the notch 521, thereby avoiding interference between the curtain 52 and the rearview mirror.
[0088] Furthermore, the sunshade 50 also includes a first magnetic member 54 and a second magnetic member 55. The first magnetic member 54 is disposed on one side wall of the notch 521, and the second magnetic member 55 is disposed on the other side wall of the notch 521. The first magnetic member 54 can be magnetically attracted to or separated from the second magnetic member 55. As the curtain 52 extends and unfolds, the rearview mirror bracket pushes open the first magnetic member 54 and the second magnetic member 55, which then extend into the notch 521. After the curtain 52 is fully unfolded, the first magnetic member 54 and the second magnetic member 55 also completely pass over the rearview mirror bracket and can automatically re-attach, thus shielding the notch 521 and preventing gaps that could lead to light leakage and affect the light-blocking effect of the sunshade assembly 100.
[0089] For example, the first magnetic 54 and the second magnetic 55 are made of magnets.
[0090] Please continue reading. Figure 2 and Figure 3 Furthermore, the transmission mechanism 20 also includes a limiting member 27, which is located in the middle of the slide rail 25 and positioned between the two transmission blocks 24. The limiting member 27 can engage with the transmission blocks 24 for limiting. The limiting member 27 is used to prevent the first slider 241 and the second slider 242 from sliding excessively, ensuring that the two scissor lift mechanisms extend and retract within the design range and preventing malfunctions.
[0091] In order to better adapt to the shading needs of trapezoidal glass, the curtain 52 in this application has a trapezoidal structure. The curtain 52 has a long side and a short side arranged relatively parallel to each other. The long side is connected to the roller shutter 51, and the short side is connected to the support rod 53.
[0092] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0093] 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.
