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.

[0039] Considering that the curtain fabric of the existing automobile windshield sunshade structure is prone to wrinkles or dragging, its working reliability is poor. The present application provides a sunshade assembly, a glass assembly and a vehicle including the sunshade assembly, which can prevent the curtain fabric from wrinkling or dragging, has high working reliability, and is easy to apply and promote.

[0040] According to one aspect of the present application, the present application provides a glass assembly, which includes a sunshade assembly 10 and a glass piece (not shown), the sunshade assembly 10 is arranged opposite to the glass piece, and the sunshade assembly 10 is used to shade the glass piece to achieve the sunshade effect of the glass piece. Optionally, the guide rail assembly 200 of the sunshade assembly 10 can be fixed on the glass piece. Optionally, the aforementioned glass piece can be, but is not limited to, suitable for a windshield, a sunroof glass, a side window glass, or a rear windshield, etc.

[0041] The present application makes the following improvements to the above-mentioned sunshade assembly 10 .

[0042] Specifically, please refer to Figure 1 and Figure 2 One embodiment of the present application provides a sunshade assembly 10, which may include a fixing seat 100, a guide rail assembly 200, a reel 300, a pull rod 400, and a power source 500. The fixing seat 100 is arranged at one end of the guide rail assembly 200. The reel 300 is rolled up with a curtain 310, and the reel 300 is fixed to the guide rail assembly 200 through the fixing seat 100. The pull rod 400 is telescopically arranged along its length direction and both ends of the pull rod 400 are respectively slidably connected to the guide rail assembly 200, the pull rod 400 is arranged parallel to the reel 300 and the pull rod 400 is connected to one end of the curtain 310. The power source 500 includes a first power output end connected to the pull rod 400, and a second power output end connected to the reel 300. The first power output end is used to drive the pull rod 400 to slide along the guide rail assembly 200 (i.e., the sliding direction Y) at a first speed and pull the curtain 310. The second power output end is used to drive the reel 300 to rotate so that the curtain 310 is wound or unwound at a second speed. The first speed is equal to the second speed. It should be noted that the reel 300 can rotate around its rotation axis, and the rotation axis extends along the length direction of the reel 300. The reel 300 can rotate around the aforementioned rotation axis under the drive of the second power output end.

[0043] The above-mentioned sunshade assembly 10 drives the pull rod 400 to slide along the guide rail assembly 200 at a first speed and pull the curtain 310 through the first power output end, and drives the reel 300 to rotate at the second power output end so that the curtain 310 rotates at a second speed. The setting of the first speed and the second speed being equal helps to synchronize the sliding movement of the pull rod 400 with the cloth-out movement of the curtain 310, thereby preventing undesirable phenomena such as wrinkles of the curtain 310 or dragging of the curtain or sliding jam of the pull rod 400 caused by asynchronous movement, thereby improving the working reliability of the sunshade assembly 10.

[0044] It is worth noting that the reel 300 of the present application is also provided with a torsion spring (not shown), which is used to eliminate the influence of the change of the winding radius of the curtain 310 on the cloth delivery speed during the winding or unwinding process, so that the cloth can always maintain the aforementioned second speed movement. It should be noted that the reel 300 is provided with a torsion spring to buffer the curtain 310 and eliminate the influence of the change of the winding radius of the curtain 310 on the cloth delivery speed during the winding or unwinding process. The related structural settings are conventional technical means in the field and will not be repeated here.

[0045] According to another aspect of the present application, the present application also provides a vehicle, the vehicle includes the sunshade assembly as described above, the vehicle also includes a glass piece and a pair of pieces, the glass piece is arranged on the pair of pieces, and the guide rail assembly 200 is connected to the pair of pieces.

[0046] It is worth noting that the aforementioned vehicles may include road vehicles, water vehicles, air vehicles, industrial equipment, agricultural equipment, or entertainment equipment, etc. For example, the vehicle may be a vehicle, which is a vehicle in a broad sense, and may be a vehicle (such as a commercial vehicle, a passenger car, a motorcycle, a flying car, a train, etc.), an industrial vehicle (such as a forklift, a trailer, a tractor, etc.), an engineering vehicle (such as an excavator, a bulldozer, a crane, etc.), agricultural equipment (such as a lawn mower, a harvester, etc.), amusement equipment, a toy vehicle, etc. The embodiment of the present application does not specifically limit the type of vehicle. For another example, the vehicle may be a vehicle such as an airplane or a ship.

[0047] It should be noted that the vehicle can be implemented as a vehicle, and the aforementioned counterpart can be the A-pillar, sunroof roof, sunroof sheet metal or side window sheet metal, interior trim, etc. of the vehicle. Optionally, the aforementioned glass component can be, but is not limited to, a front windshield, sunroof glass, side window glass or rear windshield, etc., suitable for a vehicle.

[0048] In addition, the aforementioned guide rail assembly 200 is connected to the counterpart, which means that the guide rail assembly 200 can be set on the counterpart without damaging the counterpart.

[0049] According to the above-mentioned embodiment of the present application, the present application connects the guide rail assembly 200 to the setting of the counterpart, so that the sunshade assembly 10 can avoid structural damage to the counterpart by post-installation, thereby improving the installation effect of the sunshade assembly 10. In addition, by connecting the guide rail assembly 200 to the counterpart, it is helpful to improve the structural integrity of the guide rail assembly 200 and the counterpart, thereby improving the compatibility of the sunshade assembly 10 with the counterpart, and ensuring the installation effect.

[0050] Optionally, the guide rail assembly 200 can be, but is not limited to, integrally formed on the counterpart. For example, when the counterpart is injection molded, the guide rail assembly 200 is pre-buried in the counterpart.

[0051] In some other embodiments, the guide rail assembly 200 can also be implemented as a guide groove preset on the hand piece. For example, a guide groove for sliding the pull rod 400 is formed on the hand piece by profiling technology during the early production of the hand piece, and the guide groove can directly provide the pull rod 400 for sliding installation.

[0052] Optionally, the vehicle can be implemented as a vehicle, which may include a windshield, the pair of components includes two A-pillars spaced apart, the guide rail assembly 200 is connected to the two A-pillars, and the curtain 310 has a shape consistent with the windshield in a flattened state.

[0053] Optionally, the guide rail assembly 200 can be integrally formed with the two A-pillars, which helps to improve the installation effect of the sunshade assembly 10, improve the production efficiency of the sunshade assembly 10 and optimize the structural layout. Specifically, the guide rail assembly 200 can be pre-embedded in the A-pillar during injection molding of the A-pillar.

[0054] Of course, the guide rail assembly 200 may also be but is not limited to being bonded or locked to the counterpart.

[0055] Optionally, combined Figure 1 As shown, the guide rail assembly 200 may include a first guide rail 210 and a second guide rail 220 that are spaced apart. An opening 10a is formed between the first guide rail 210 and the second guide rail 220, and the curtain 310 may be in a shape consistent with the opening 10a when flattened, thereby increasing the sunshade area and sunshade effect of the sunshade curtain assembly 10.

[0056] Specifically, when the first guide rail 210 and the second guide rail 220 of the present application are connected to the aforementioned opponent, the opening 10a formed between the first guide rail 210 and the second guide rail 220 will present different shapes according to different implementation methods of the opponent. The present application allows the curtain 310 to present a shape consistent with the opening 10a in a flattened state, so that the curtain 310 can completely cover the aforementioned opening 10a, thereby improving the sunshade effect.

[0057] For example, at the front windshield of the vehicle, when the opponent is implemented as two A-pillars of the car, the opening 10a between the two A-pillars is the installation window of the front windshield. Correspondingly, in this embodiment, the curtain 310 is implemented to be in a shape consistent with the opening 10a between the two A-pillars in a flat state, which helps to improve the sunshade effect of the front windshield.

[0058] More specifically, the windshield is generally in the shape of a trapezoid that is wide at the bottom and narrow at the top, so the opening 10a between the two A-pillars is also in the shape of a trapezoid that is wide at the bottom and narrow at the top. Thus, in this embodiment, one end of the curtain 310 connected to the tie rod 400 can be implemented as a narrow side with the same length as the upper edge of the opening 10a, and the other end of the curtain 310 can be implemented as a wide side with the same length as the lower edge of the opening 10a, so that the curtain 310 can be guaranteed to just cover the opening 10a between the two A-pillars in a flat state, and then the full sunshade effect of the windshield can be achieved.

[0059] For example, in some other embodiments, when the opponent parts are implemented as the A-pillar and B-pillar of the vehicle, the first guide rail 210 and the second guide rail 220 can be connected to the side window structure of the vehicle, and the curtain 310 can be in a shape consistent with the side window, thereby achieving a full shading effect on the side window.

[0060] For example, in some other embodiments, when the opponent part is implemented as a sunroof of a vehicle, the first guide rail 210 and the second guide rail 220 can be connected to the sunroof structure of the vehicle, and the curtain 310 can be in a shape consistent with the sunroof window, thereby achieving a full shading effect on the sunroof.

[0061] It is worth noting that the curtain 310 of the present application can be manufactured into a shape consistent with the window in each of the above-mentioned scenarios to achieve a full sunshade effect, thanks to the fact that the pull rod 400 of the present application can be retracted along its length direction to achieve the adaptation of the pull rod 400 in different application scenarios. Therefore, the matching design of the retractable setting of the pull rod 400 and the variable shape of the curtain 310 helps to improve the adaptability of the sunshade assembly 10 and improve the sunshade effect of the sunshade assembly 10.

[0062] Optionally, the power source 500 may include, but is not limited to, a first power device (not shown) and a second power device (not shown), the first power device may have a first power output end, and the second power device may have a second power output end, so that the motion control of the pull rod 400 and the curtain 310 can be achieved respectively. Optionally, the first power device and the second power device may be implemented as, but are not limited to, electric motors and other devices.

[0063] Optionally, an extension direction of the first guide rail 210 intersects with an extension direction of the second guide rail 220 and is arranged at an angle.

[0064] Adaptively, the sunshade assembly 10 is retractable through the pull rod 400, so that the pull rod 400 can be installed between the first guide rail 210 and the second guide rail 220 with unequal spacing, which helps to improve the adaptability of the sunshade assembly 10 in various application scenarios.

[0065] For example, when the above-mentioned pair of counter parts is implemented as two A-pillars of a car, since the shape of the front windshield of the car is generally trapezoidal, the distance between the two A-pillars will decrease or increase along the height direction of the car body. The present application uses the retractable setting of the pull rod 400 to enable the pull rod 400 to slide smoothly between the two A-pillars, thereby improving the sliding smoothness of the pull rod 400 and further improving the working reliability of the sunshade assembly 10.

[0066] Optionally, combined Figure 2 As shown, the power source 500 may include a motor 510, a synchronous wheel 520 and a synchronous belt 530. The synchronous belt 530 is sleeved on the synchronous wheel 520, and the synchronous belt 530 is connected to the pull rod 400. The motor 510 is used to drive the synchronous wheel 520 to rotate to drive the synchronous belt 530 to move, and the synchronous belt 530 is used to drive the pull rod 400 to slide. In this way, through the driving action of a single motor 510 and the driving action of the synchronous wheel 520 and the synchronous belt 530, the pull rod 400 and the reel 300 can be driven simultaneously, which helps to improve the structural compactness and driving consistency of the sunshade assembly 10, and improves work efficiency and work reliability.

[0067] Optionally, the synchronous wheel 520 may include a first driving wheel and a first driven wheel, and the synchronous belt 530 may include a first belt, the first driving wheel is rotatably connected to the fixed seat 100 on the first guide rail 210, the first driven wheel is arranged at one end of the first guide rail 210 away from the fixed seat 100, the first belt is sleeved on the first driving wheel and the first driven wheel, and the first belt is arranged along the extension direction of the first guide rail 210; the synchronous wheel 520 may also include a second driving wheel and a second driven wheel, and the synchronous belt 530 may include a second belt, the second driving wheel is rotatably connected to the fixed seat 100 on the second guide rail 220, the second driven wheel is arranged at one end of the second guide rail 220 away from the fixed seat 100, the second belt is sleeved on the second driving wheel and the second driven wheel, and the second belt is arranged along the extension direction of the second guide rail 220, so that the first belt and the second belt can simultaneously drive the pull rod 400 to slide along the extension direction (i.e., sliding direction Y) of the first guide rail 210 and the second guide rail 220 at both ends of the pull rod 400, which helps to improve the movement stability of the pull rod 400.

[0068] Optionally, see Figure 2 and Figure 3 As shown, the power source 500 may also include two reversing mechanisms 540, one end of the reel 300 is connected to the first driving wheel via a reversing mechanism 540, and the other end of the reel 300 is connected to the second driving wheel via another reversing mechanism 540. In this way, the reversing mechanisms 540 at both ends of the reel 300 can be adjusted at the same time to adjust the setting angle between the reel 300 and the synchronous wheel 520, thereby optimizing the position arrangement of the reel 300 and improving the adaptability of the sunshade assembly 10.

[0069] Optionally, continue to Figure 2 and Figure 3 As shown, the reversing mechanism 540 has a first axis L1 and a second axis L2, the synchronous wheel 520 can rotate around the first axis L1, the first axis L1 passes through the wheel center of the synchronous wheel 520, the reel 300 can rotate around the second axis L2, and the first axis L1 and the second axis L2 are set at an angle α or overlap each other. In this way, the setting angle between the reel 300 and the synchronous wheel 520 can be adjusted in time according to the cloth delivery angle of the curtain 310 to optimize the position arrangement of the reel 300 and improve the adaptability of the sunshade assembly 10.

[0070] Specifically, the first axis L1 can be arranged to coincide with the second axis L2. Understandably, at this time, the reel 300 can be regarded as being arranged perpendicularly to the plane of the synchronous wheel 520. More specifically, the synchronous wheel 520 can be regarded as a plane, and the reel 300 can be regarded as a straight line connecting the wheel center of the synchronous wheel 520 and perpendicular to the plane where the synchronous wheel 520 is located. Under this setting, the synchronous wheel 520 and the reel 300 have the same rotational angular velocity, and this setting can be applied to the scene where the relative position adjustment space of the reel 300 and the synchronous wheel 520 is large.

[0071] It is worth noting that the first axis L1 can be set at an angle α with the second axis L2. At this time, the reel 300 and the synchronous wheel 520 can be set at a certain angle, which can be suitable for scenarios where the adjustment space of the relative position of the reel 300 and the synchronous wheel 520 is relatively small, and then the relative position arrangement of the reel 300 and the synchronous wheel 520 is optimized, thereby improving the adaptability of the sunshade assembly 10 in various scenarios.

[0072] Optionally, the value range of the aforementioned angle α can be set to 0°-30°, such as the angle α can be 0°, 10°, 20° or 30°.

[0073] For example, when the opponent parts are implemented as two A-pillars of a vehicle, the sunshade assembly 10 of the present application can be used for shading the windshield. Since the curvature of the windshield of the vehicle is relatively large, the angle α can be appropriately increased, and then the position arrangement of the roller 300 can be optimized to improve the structural compactness of the vehicle.

[0074] It is understandable that when the sunshade assembly 10 of the present application is used to shade the side windows of a vehicle, since the curvature of the side windows is small, the angle α can be appropriately reduced, thereby optimizing the position arrangement of the roller 300 and improving the structural compactness of the vehicle.

[0075] Optionally, the aforementioned reversing mechanism 540 may be implemented as, but not limited to, a universal joint, a flexible shaft, a worm gear, or a bevel gear, etc.

[0076] Optionally, the reversing mechanism 540 may include a constant velocity universal joint, so that while taking into account the need to adjust the relative position of the reel 300 and the pull rod 400, that is, taking into account the adjustment of the delivery angle of the curtain 310, it can ensure that the rotational angular velocity of the synchronous wheel 520 is consistent with that of the reel 300, and then prevent the curtain 310 from wrinkling or dragging and the pull rod 400 from sliding and getting stuck due to the asynchronous winding or unwinding of the curtain 310 and the movement of the pull rod 400, thereby improving the working reliability of the sunshade assembly 10.

[0077] It is worth noting that the aforementioned constant velocity universal joint may include a quasi-constant velocity universal joint. For example, the reversing mechanism 540 may be, but is not limited to, a double-type quasi-constant velocity universal joint, a convex block quasi-constant velocity universal joint, a tripod quasi-constant velocity universal joint, or a spherical roller quasi-constant velocity universal joint. Alternatively, the reversing mechanism 540 may be, but is not limited to, a ball-fork type constant velocity universal joint or a ball cage type constant velocity universal joint.

[0078] Optionally, combined Figure 3 As shown, the reversing mechanism 540 may also include a cross universal joint, which helps to improve the transmission efficiency, load-bearing capacity, working stability and durability of the reversing mechanism 540. In addition, the use of a cross universal joint also helps to reduce maintenance costs, and helps to improve installation flexibility and reduce the difficulty of disassembly and assembly.

[0079] Furthermore, the reel 300 has a radius R1, the synchronous wheel 520 has a radius R2, and the rotation angle of the synchronous wheel 520 is β. When the first axis L1 and the second axis L2 are arranged at an angle α, the radius R1 of the reel 300 is configured as In this way, it is possible to overcome the influence of the second speed of the curtain 310 coming out of the cloth and the first speed of the pull rod 400 sliding due to the non-uniform speed characteristics of the cross universal joint.

[0080] Specifically, combined Figure 3 As shown, the cross universal joint may include a first yoke 541 and a second yoke 542, one end of the first yoke 541 is rotatably connected to one end of the second yoke 542, the first yoke 541 has a first axis L1, the second yoke 542 has a second axis L2, the other end of the first yoke 541 is connected to the synchronous wheel 520, and the other end of the second yoke 542 is connected to the reel 300. The rotational angular velocity of the reel 300 may be set to W1, the rotational angular velocity of the synchronous wheel 520 may be set to W2, the rotation angle of the synchronous wheel 520 is β, the cross-sectional radius of the reel 300 is R1, and the circumferential radius of the synchronous wheel 520 is R2.

[0081] According to the unequal speed characteristic formula of the cross universal joint, we can get: It can be seen that when the synchronous wheel 520 rotates at a constant speed, the rotational angular velocity W1 of the reel 300 changes periodically. In order to ensure that the curtain 310 and the pull rod 400 run synchronously, the radius R1 of the reel 300 can be calculated using the corresponding function cross-section formula: In addition, according to the rotational linear velocity of the reel 300 , the rotational linear speed of the synchronous wheel 520 , so that the rotational linear velocity V1 of the reel 300 can be calculated at the radius R1 using the corresponding function cross-section formula By maintaining a uniform speed under the condition of constant speed, the uneven rotational linear velocity V1 of the reel 300 caused by the non-uniform speed characteristics of the cross universal joint can be eliminated, thereby eliminating the influence of the first speed of the curtain 310 coming out of the cloth and the second speed of the pull rod 400 sliding being different, thereby improving the working reliability of the sunshade assembly 10.

[0082] It should be noted that the above formula for the unequal speed characteristic of the cross universal joint and the reasoning process of V1 being a uniform speed are common knowledge and will not be demonstrated here.

[0083] It is worth noting that the combination Figure 4 As shown, in the actual design process of the radius R1 of the reel 300, since the radius R2 of the synchronous wheel 520 and the angle α between the first axis L1 and the second axis L2 can be set to a specific fixed value according to actual conditions, the radius R1 of the reel 300 will change periodically with the change of β.

[0084] Combination Figure 4 As shown, by way of example, the aforementioned formula is applied The distribution image of the radius R1 of the scroll 300 section is compared with the standard circle with the joint equation y=sinβ, x=cosβ. When R2 is set to 20mm and the angle α is set to 10°, it can be seen that when β changes from 0 to 360°, at the initial position (angle β=0°), the radius R1 of the reel 300 is the largest, and then slowly decreases; when β=90°, the radius R1 of the reel 300 reaches the minimum value, and then slowly increases; when β=180°, the radius R1 of the reel 300 reaches the maximum value, and then slowly decreases. Therefore, the change of the radius R1 of the reel 300 will change periodically within the range of 180° of β.

[0085] It is understandable that the radius R2 of the synchronous wheel 520 can also be set to 30 mm, 40 mm or 50 mm, etc. The angle α can also be set to 10°, 20° or 30°, etc. The actual sizes of R2 and α can be set according to the structural layout requirements of the sunshade assembly 10, and are not limited here.

[0086] Optionally, at least a portion of the second fork 542 can protrude from the curtain 310 along the length direction of the reel 300, so that the second fork 542 can avoid the curtain 310, so that when the second fork 542 changes the angle α relative to the first fork 541, the second fork 542 can avoid affecting the winding radius of the reel 300, thereby optimizing the structural layout.

[0087] Optionally, revisit Figure 1 The pull rod 400 may include a sleeve rod 410, a first telescopic rod 420 and a second telescopic rod 430. The first telescopic rod 420 and the second telescopic rod 430 are respectively telescopically arranged on the sleeve rod 410 along both ends of the sleeve rod 410. When the pull rod 400 moves along the sliding direction Y of the guide rail assembly 200, the first telescopic rod 420 and the second telescopic rod 430 can telescopically move relative to the sleeve rod 410, thereby ensuring the smoothness of the movement of the pull rod 400.

[0088] Optionally, combined Figure 2 As shown, the first telescopic rod 420 and the second telescopic rod 430 are each provided with a slider 440 at one end away from the sleeve rod 410, and the first telescopic rod 420 and the second telescopic rod 430 are respectively slidably connected to the guide rail assembly 200 through the slider 440, which can further improve the movement smoothness of the pull rod 400.

[0089] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, 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.

[0090] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood 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.
