Description

Technical Field

[0001] The present application relates to the technical field of automobile sunshades, and in particular to a sunshade assembly, a glass assembly and a vehicle. Background Art

[0002] With the development of society and the improvement of living standards, cars have become an indispensable means of transportation in people's daily life and work. While cars bring convenience to people's travel, they also encounter some new problems during use. For example, in the hot summer, strong sunlight directly shines into the car, which will cause the temperature inside the car to rise rapidly, not only reducing people's riding comfort, but also accelerating the aging of electronic components and interior fabrics in the car. In response to this, sunroofs and door glasses can often use shading solutions such as dimming modules to block or reduce light entering the car, but the front windshield cannot replicate the mode of the sunroof due to its special installation position, so the front windshield sunshade has become the market choice.

[0003] The front windshield sunshade is mainly composed of a drive module and a roller sunshade. The drive module is connected to the roller sunshade by driving the curtain to extend or retract to achieve shading and storage of the front windshield. However, the existing drive module has a complex structure and a large volume. It will take up more space in the car when installed, and it is easy to interfere with the existing structural components in the car, and it is easy to produce abnormal noises and affect the user experience. Therefore, there are great limitations in its applicability. Summary of the invention

[0004] Based on this, it is necessary to provide a sunshade assembly, a glass assembly and a vehicle to address the problems of complex structure, large installation space, affecting the user experience and having limited applicability.

When equipped in vehicles of different models, it has little interference and influence on the existing mechanisms around the installation position, thereby having higher and more flexible applicability; in the initial state, the telescopic mechanism remains in a retracted state and the sunshade curtain is in a retracted position at the same time. When sunlight shines on the glass, the driving source is started, the driving source drives the transmission mechanism, and the transmission mechanism finally drives the telescopic mechanism to extend from the retracted state along the second direction of the sunshade assembly, thereby driving the sunshade to unfold and block the surface of the glass, thereby preventing sunlight from passing through the glass and entering the car; when the sunshade is finished, the driving source is controlled to output a reverse driving force to drive the telescopic mechanism to retract and the sunshade to be recovered, and the sunshade exposes the glass again without affecting the normal use of the vehicle.

However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0046] In the description of the present application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0047] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0048] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0049] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0050] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, 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 implementation method.

[0051] The present 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] The vehicle at least includes a body and a glass assembly, and the glass assembly is installed on the body. It is easy to understand that the glass assembly is installed at the front of the vehicle body, specifically at the front side of the cockpit, to block the oncoming wind when the vehicle is driving.

[0053] Optionally, the glass assembly may be, but is not limited to, any one of a windshield assembly, a rear windshield assembly, a skylight glass assembly, etc. For example, the glass assembly in the present application is a windshield assembly.

[0054] In one embodiment, the glass assembly includes glass and a sunshade assembly 100 . The sunshade assembly 100 is installed on the inner side of the glass, and the sunshade curtain 50 can completely cover or expose the glass.

[0055] It is easy to understand that the sunshade 50 has an unfolded state and a retracted state. The sunshade 50 in the unfolded state completely blocks the glass; the sunshade 50 in the retracted state reveals the glass.

[0056] For example, the sunshade assembly 100 is located inside the cockpit and can be installed anywhere in the vehicle, such as above the center console, inside the center console, or below the center console. The location can be flexibly selected according to actual needs.

[0057] When the sunshade 50 completely exposes the glass, the sunshade 50 will not block the glass, and thus will not affect the vision of the driver and passengers, thus ensuring driving safety. When the sunshade 50 completely blocks the glass, sunlight will not be able to penetrate into the vehicle through the glass, thus avoiding discomfort to the driver and passengers in the vehicle, and aging damage to the fabrics, electrical components, etc. in the vehicle.

[0058] See also Figures 1 to 3 , which is a sunshade assembly 100 shown in an embodiment of the present application, includes a mounting seat 10, a transmission mechanism 20, a driving source 30, a telescopic mechanism 40 and a sunshade curtain 50.

[0059] The transmission mechanism 20 can be movably arranged on the mounting base 10, the driving source 30 is installed on the mounting base 10, and the driving source 30 is arranged on one side of the transmission mechanism 20 along the first direction of the sunshade assembly 100, and the driving source 30 is connected to the transmission mechanism 20 in a transmission manner; the telescopic mechanism 40 is connected to the transmission mechanism 20 in a transmission manner, and the transmission mechanism 20 can drive the telescopic mechanism 40 to extend or contract along the second direction of the sunshade assembly 100, and the second direction intersects with the first direction; the sunshade curtain 50 is connected to the telescopic mechanism 40, and can be unfolded as the telescopic mechanism 40 extends or retracted as the telescopic mechanism 40 contracts.

[0060] For example, taking the glass and the vehicle body in the installed state as reference systems, the first direction of the sunshade assembly 100 is specifically Figure 1 and Figure 2 The X-axis direction in the figure 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] That is, the sunshade 50 uses a lifting motion to cover or reveal the glass.

[0062] Specifically, the transmission mechanism 20 in the present application includes a transmission wheel group, a transmission member 23 and a transmission block 24. The transmission wheel group is rotatably arranged on the mounting seat 10, the transmission member 23 is wrapped around the outside of the transmission wheel group, and the transmission block 24 is transmission connected to the transmission member 23; the driving source 30 is transmission connected to the transmission wheel group, and the telescopic mechanism 40 is transmission connected to the transmission block 24. The transmission block 24 can drive the telescopic mechanism 40 to extend or contract along the second direction of the sunshade assembly 100.

[0063] In summary, the implementation of 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 with the glass to provide the glass with shading capability by blocking the glass; specifically, the mounting seat 10 integrates the transmission mechanism 20, the driving source 30, the telescopic mechanism 40 and the sunshade curtain 50 into one body, and forms a flat and long structure, so that the overall structural layout of the sunshade assembly 100 is compact, the volume is small, and it occupies less installation space. When equipped in vehicles of different models, the interference and influence on the existing mechanisms around the installation position is small, so that it has higher and more flexible applicability; in the initial state, the telescopic mechanism 40 remains in the retracted state and the sunshade curtain 50 is in the retracted position at the same time. When sunlight is directed to the glass , start the driving source 30, the driving source 30 drives the transmission wheel group to rotate, the transmission wheel group drives the transmission member 23 to move, so that the transmission member 23 can then drive the transmission block 24 to move synchronously, and the transmission block 24 finally drives the telescopic mechanism 40 to extend from the retracted state along the second direction of the sunshade assembly 100, thereby driving the sunshade curtain 50 to unfold and block the surface of the glass, thereby achieving the purpose of blocking sunlight from passing through the glass and entering the vehicle; when the sunshade is finished, the driving source 30 is controlled to output a reverse driving force to drive the telescopic mechanism 40 to retract and the sunshade curtain 50 to be recovered, and the sunshade curtain 50 exposes the glass again, which does not affect the normal use of the vehicle. The transmission mechanism 20 and the telescopic mechanism 40 have simple structures, and the transmission is reliable and effective, which avoids the generation of abnormal noise and affects 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 may be a split structure or may be connected as an integral structure via an intermediate connecting member, depending on 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 driving source 30 is set on the first support 11, the transmission wheel group includes a driving wheel 21 and a driven wheel 22, the driving wheel 21 is rotatably set on the first support 11 and connected to the driving source 30, the driven wheel 22 is rotatably set on the second support 12, and the transmission member 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 with the prior art in which the driving source 30 is installed in the middle of the transmission mechanism 20 and the sunshade 50, the present solution arranges the driving source 30 on one side of the sunshade 50 and connects it to the transmission wheel set, thereby avoiding occupying the core space in the middle area of ​​the vehicle and making full use of the space in the side area of ​​the vehicle body. The driving source 30 and the transmission mechanism 20 form a long and flat installation structure, which has lower requirements for the installation space.

[0067] When working, the driving source 30 drives the driving wheel 21 to rotate, and the driving wheel 21 then drives the transmission member 23 and the driven wheel 22 to rotate, the power output is stable and the response speed is fast, the structure is simple, and it helps to avoid abnormal noise. The two ends of the sunshade 50 are respectively fixed on the first support 11 and the second support 12, the installation structure is simple and the stability is good.

[0068] Specifically, in an optional embodiment, the driving wheel 21 includes a first synchronous wheel, the driven wheel 22 includes a second synchronous wheel, and the transmission member 23 includes a synchronous belt, which is meshed and wound around the first synchronous wheel and the second synchronous wheel. That is, the transmission mechanism 20 constitutes a synchronous belt transmission mechanism 20.

[0069] Alternatively, as an alternative to the above embodiment, 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 above-mentioned synchronous belt transmission mechanism 20 or sprocket transmission mechanism 20 can avoid slipping by virtue of the meshing transmission relationship of the meshing teeth, which helps to ensure transmission efficiency and stability, prevent abnormal noise, and facilitate subsequent repair and maintenance at a low cost.

[0071] Please continue reading Figure 2 and Figure 3 On the basis of any of the above embodiments, the transmission member 23 includes a first transmission part 231 and a second transmission part 232, and the first transmission part 231 and the second transmission part 232 are arranged opposite to each other along the second direction of the sunshade assembly 100. More specifically, a line connecting the wheel center of the driving wheel 21 and the wheel 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 respectively 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 on the first transmission portion 231 , and the second slider 242 is disposed on the second transmission portion 232 . The first slider 241 and the second slider 242 can move toward or away from each other.

[0073] The telescopic mechanism 40 is transmission-connected to the first slider 241 and the second slider 242 .

[0074] In the present application, the types of the telescopic mechanism 40 include but are not limited to an organ mechanism, a spiral mechanism, a scissor mechanism, etc. For ease of understanding of the solution, the telescopic mechanism 40 is described below as a scissor mechanism.

[0075] Combination Figure 2 and Figure 3 As shown, for example, when the transmission member 23 is driven to rotate in the counterclockwise direction, the first slider 241 installed on the first transmission part 231 and the second slider 242 installed on the second transmission part 232 slide towards each other, and the first slider 241 and the second slider 242 output a driving force to the scissor mechanism at this time, so that the scissor mechanism performs an extension movement, thereby driving the sunshade 50 to unfold and cover the glass; on the contrary, when the transmission member 23 rotates in the clockwise direction, the first slider 241 and the second slider 242 slide away from each other, and output a pulling force to the scissor mechanism, so that the scissor mechanism performs a recovery movement, thereby driving the sunshade 50 to retract and reveal the glass again. The driving scheme formed by the cooperation of the first slider 241, the second slider 242 and the scissor mechanism does not need to install guide rails and other components for the sunshade 50, and the driving method of the sunshade 50 is simple and efficient, and there is no need to dismantle and modify the original structural parts in the vehicle too much, so the installation and use are 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 stability of the first slider 241 and the second slider 242 in transmitting the scissor mechanism, the transmission mechanism 20 also includes a slide rail 25, one end of the slide rail 25 is arranged on the first support 11, and the other end of the slide rail 25 is arranged on the second support 12, and the first slider 241 and the second slider 242 can be slidably installed on the slide rail 25.

[0077] For example, the slide rail 25 is a channel-shaped steel strip member made of aluminum material, which is installed and fixed to the first support 11 and the second support 12 by at least one of screwing, clamping, riveting, etc. It has a simple structure and light weight, 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 further includes a guide block 26, which is disposed at one end of the slide rail 25 and the first support 11, and the guide block 26 is in guiding cooperation with the transmission member 23. On the one hand, the guide block 26 is in sliding cooperation with the transmission member 23, and plays a guiding and limiting role on the transmission member 23, thereby ensuring the smooth rotation of the transmission member 23; on the other hand, the guide block 26 also presses the transmission member 23 to play a certain tensioning effect, thereby preventing the transmission member 23 from deforming and elongating and easily falling off from the driving wheel 21 and the driven wheel 22, thereby affecting the reliable operation of the transmission mechanism 20.

[0079] It is necessary to explain that the contact portion between the guide block 26 and the transmission member 23 adopts a smooth structure (eg, a convex arc surface), which is beneficial to reducing the wear on the transmission member 23 and increasing the service life of the transmission member 23.

[0080] Please continue reading Figure 2 In one embodiment, the scissors 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 shaft 45, a second pin shaft 46 and a third pin shaft 47. The first active fork arm 41 is rotatably connected to the second active fork arm 42 through the first pin shaft 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 through the second pin shaft 46, one end of the second active fork arm 42 is rotatably connected to the second slider 242, and the other end of the second active fork arm 42 is rotatably connected to one end of the second driven fork arm 44 through the third pin shaft 47.

[0081] Please continue reading Figure 1 The sunshade curtain 50 includes a rolling curtain cylinder 51, a curtain 52 and a support rod 53. The rolling curtain cylinder 51 is arranged on the mounting seat 10. One side of the curtain 52 is wound and installed on the rolling curtain cylinder 51. The curtain 52 can be unfolded or recovered relative to the rolling curtain cylinder 51. The other side of the curtain 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 closer to each other, 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 closer to each other, so that the length of the scissors mechanism along the second direction becomes larger, and a pushing effect is exerted on the support rod 53 and the curtain 52, so that the curtain 52 stretches and unfolds relative to the rolling roller 51 to achieve glass shielding; when the first slider 241 and the second slider 242 slide away, the curtain 52 is rolled up to the inside of the rolling roller 51, so that the curtain 52 is recovered and the glass is exposed.

[0083] Furthermore, a winding spring shaft (not shown in the figure) is installed inside the curtain roller 51, and one side of the curtain 52 is wound and connected to the winding spring shaft. When the curtain 52 is stretched and unfolded, the torsion spring shaft accumulates elastic torsion force; when the curtain 52 needs to be recovered, 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, ensuring that the curtain 52 is better and more flatly recovered to the inside of the curtain roller 51.

[0084] For example, the winding spring shaft is specifically composed of a rotatable winding shaft and a torsion spring assembly installed on at least one end of the winding shaft.

[0085] Preferably, considering that the area of ​​the curtain 52 is usually large, the size of a single scissor mechanism needs to be very large, which affects the installation, and the stability of a single scissor mechanism is also slightly poor. Therefore, on the basis of any of the above embodiments, two transmission blocks 24, scissor mechanisms and support rods 53 are provided and assembled one by one. The two support rods 53 and the two scissor mechanisms are arranged side by side and spaced apart along the first direction of the sunshade assembly 100.

[0086] It is easy to understand that when the transmission member 23 rotates, it drives the two groups of first sliders 241 and second sliders 242 to move synchronously, thereby ensuring the synchronization of the movement of the two groups of scissor mechanisms and the support rod 53, ensuring that the curtain 52 can be unfolded or retracted with a flat structure, improving the user experience, and also helping to ensure that the unfolded curtain 52 does not tilt and can completely cover the glass to prevent light leakage.

[0087] Please continue reading Figure 1 A rearview mirror is generally 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 curtain roller 51, and the notch 521 is arranged between two support rods 53. When the curtain 52 is unfolded, the bracket of the rearview mirror just 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 component 54 and a second magnetic component 55. The first magnetic component 54 is arranged on one side of the notch groove 521, and the second magnetic component 55 is arranged on the other side of the notch groove 521. The first magnetic component 54 can be magnetically attracted or separated from the second magnetic component 55. As the curtain 52 continues to stretch and unfold, the bracket of the rearview mirror pushes the first magnetic component 54 and the second magnetic component 55 open and extend into the notch groove 521. After the curtain 52 is in a fully unfolded state, the first magnetic component 54 and the second magnetic component 55 also just completely pass the bracket of the rearview mirror and can be automatically adsorbed again to shield the notch groove 521, avoiding the formation of gaps that cause light leakage and affect the shading effect of the sunshade assembly 100.

[0089] For example, the first magnetic attraction member 54 and the second magnetic attraction member 55 are magnets.

[0090] Please continue reading Figure 2 and Figure 3 Furthermore, the transmission mechanism 20 further includes a limiter 27, which is disposed in the middle of the slide rail 25 and arranged between the two transmission blocks 24, and the limiter 27 can cooperate with the transmission blocks 24. The limiter 27 is used to prevent the first slider 241 and the second slider 242 from sliding excessively, ensuring that the two scissor mechanisms telescope within the design range to avoid failure.

[0091] In order to better adapt to the shielding needs of the trapezoidal structure of glass, the curtain 52 in the present application has a trapezoidal structure. The curtain 52 has a long side and a short side that are relatively parallel. 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-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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 above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
