Description

Technical Field

[0001] This invention relates to the field of automotive technology, and in particular, to an automobile and its sunshade assembly. Background Technology

[0002] Currently, it is very common to install sunroofs in cars during manufacturing. When the sunroof is not in use, a sunshade is needed to block it to prevent direct sunlight from entering the car, which can cause the interior temperature to rise and affect the riding experience.

[0003] In existing technologies, such as Figure 1 As shown, the sunshade assembly includes a front crossbeam, a rear crossbeam, side rails, and a sunshade component. The sunshade component mainly includes a roller 102, a curtain 103, a side anti-slip structure, and aluminum edge strips. The sunshade component is fixed to the sunroof frame via the roller 102 and the side anti-slip structure. The roller 102 can be fixed to either the front or rear crossbeam, and then fixed to the roof 101 via screws through the locking holes on the sunroof frame.

[0004] The sunshade assembly occupies the largest space along the Z-axis (height direction) of the vehicle body at the location where the roller is fixed, and this space cannot be reduced. For example, the diameter of the roller 102 in the sunshade assembly is φ20mm, and the overall diameter of the curtain 103 after rolling up is approximately φ48mm. Furthermore, because the gap between the sunshade assembly and the vehicle body in the rolled-up state must be greater than 8mm, ... Figure 1 As shown, the height H of the sunshade assembly in the Z direction (i.e., the height direction) of the vehicle body at the part of the roller 102 where the curtain 103 needs to be rolled up is 84.8mm, therefore it needs to occupy 84.8mm of height space inside the vehicle. Summary of the Invention

[0005] The purpose of this invention is to provide an automobile and its sunshade assembly to solve the technical problem that the current sunshade assembly occupies too much space in the Z-direction (i.e., the height direction) of the vehicle body.

[0006] The above-mentioned objectives of the present invention can be achieved by the following technical solutions:

[0007] This invention provides a sunshade assembly, comprising: two slide rails arranged opposite to each other, the slide rails having an extending direction; a plurality of sunshade components arranged and connected from front to back along the extending direction, each sunshade component including a curtain, a roller structure, and two fixed sliders, the curtain being wound around the roller structure, and the two fixed sliders being installed at both ends of the roller structure; the sunshade component arranged at the front is the first sunshade component, and the sunshade component arranged at the back is the last sunshade component, the two fixed sliders of the last sunshade component being fixedly mounted on the two slide rails, and the two fixed sliders of the other sunshade components slidingly engaging with the slide rails along the extending direction; and a driving mechanism having a movable end capable of moving along the extending direction, the movable end being connected to the curtain of the first sunshade component.

[0008] In an embodiment of the present invention, between two adjacent sunshade curtain assemblies, the fixed slider of the preceding sunshade curtain assembly is connected to the front end of the curtain fabric of the following sunshade curtain assembly through a curtain fabric connecting strip, and the two ends of the curtain fabric connecting strip are fixed to the two fixed sliders of the preceding sunshade curtain assembly.

[0009] In an embodiment of the present invention, the curtain connecting strip is provided with a first slot, and the curtain of the subsequent sunshade assembly is secured in the first slot by a first support member.

[0010] In an embodiment of the present invention, each of the sunshade curtain assemblies is provided with a guide strip at the front, and the two ends of the guide strip are fixed to the two fixed sliders of the adjacent sunshade curtain assembly behind it.

[0011] In an embodiment of the present invention, between two adjacent sunshade curtain assemblies, the fixed slider of the preceding sunshade curtain assembly is connected to the front end of the curtain fabric of the following sunshade curtain assembly through a bushing. The roller structure of the preceding sunshade curtain assembly rolls the curtain fabric into the bushing, and the two ends of the bushing are fixed to the two fixed sliders of the preceding sunshade curtain assembly.

[0012] In an embodiment of the present invention, the bushing has an opening and a second slot is provided inside the bushing. In two adjacent sunshade curtain assemblies, the front end of the curtain of the preceding sunshade curtain assembly can extend out from the opening, and the front end of the curtain of the following sunshade curtain assembly can extend into the opening and be secured in the second slot by the second support member.

[0013] In an embodiment of the present invention, the curtain is provided with a locking structure. When the curtain of the sunshade assembly is opened to a preset position, the locking structure can cooperate with the component in front of it to prevent the curtain from continuing to unfold.

[0014] In an embodiment of the present invention, the driving mechanism includes a motor, a driving connecting strip, and two driving flexible shafts. The driving connecting strip is arranged in front of the first sunshade assembly and connected to the curtain fabric of the first sunshade assembly. One end of each of the two driving flexible shafts is connected to both ends of the driving connecting strip through two flexible shaft sliders and is slidably engaged with the two slide rails along the extension direction. The motor drives the two driving flexible shafts to move relative to each other, thereby causing the two flexible shaft sliders to slide synchronously along the extension direction.

[0015] In an embodiment of the present invention, the drive connecting strip is provided with a third slot, and the front end of the curtain of the first sunshade assembly is secured in the third slot by a third support member.

[0016] In an embodiment of the present invention, the sunshade assembly further includes a front crossbeam and a rear crossbeam, the front ends of the two slide rails are fixed to both ends of the front crossbeam, the rear ends of the two slide rails are fixed to both ends of the rear crossbeam, and the motor is mounted on the front crossbeam.

[0017] In an embodiment of the present invention, the curtain has an initial unfolding state and an end unfolding state. In the initial unfolding state, the curtain is subjected to an initial winding force provided by the corresponding roller structure. In the end unfolding state, the curtain is subjected to an end winding force provided by the corresponding roller structure. During the unfolding process of the curtains of two adjacent sunshade curtain assemblies, the end winding force experienced by the curtain of the preceding sunshade curtain assembly is less than the initial winding force experienced by the curtain of the following sunshade curtain assembly.

[0018] The present invention also provides an automobile including the above-described sunshade assembly.

[0019] The features and advantages of this invention are:

[0020] The sunshade assembly and automobile of the present invention, by setting up multiple sunshade assemblies connected from front to back, and connecting the movable end of the drive mechanism to the curtain of the foremost sunshade assembly, and fixing only the fixed slider of the rearmost sunshade assembly to the slide rail, wherein the fixed slider of the sunshade assembly can slide under the drive of the drive mechanism, so that when the movable end of the drive mechanism moves forward in the extension direction, the curtains of the multiple sunshade assemblies can be unfolded in sections, and when the movable end of the drive mechanism moves backward in the extension direction and cooperates with the winding force of the roller structure of the multiple sunshade assemblies, the curtains of the multiple sunshade assemblies can be rolled up in sections, thereby realizing the sunroof shading and use. Compared with the prior art, the sunshade assembly of the present invention occupies significantly less space in the height direction. Attached Figure Description

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Implementation Method 1

[0042] like Figure 2 and Figure 3 As shown, the present invention provides a sunshade assembly, comprising: two slide rails 1, arranged opposite to each other, the slide rails 1 having an extending direction X; a plurality of sunshade components 2, arranged and connected from front F to rear B along the extending direction X, the sunshade component 2 including a curtain 21, a roller structure 22 and two fixed sliders 23, the curtain 21 being wound around the roller structure 22, the two fixed sliders 23 being installed at both ends of the roller structure 22; the sunshade component 2 arranged at the frontmost position is the first sunshade component 2', the sunshade component 2 arranged at the rearmost position is the last sunshade component 2', the two fixed sliders 23 of the last sunshade component 2' are fixedly arranged on the two slide rails 1, the two fixed sliders 23 of the other sunshade components 2 are slidably engaged with the slide rails 1 along the extending direction X; a drive mechanism 6 having a movable end 61' that can move along the extending direction X, the movable end 61' being connected to the curtain 21 of the first sunshade component 2'.

[0043] The sunshade assembly of the present invention comprises multiple sunshade components 2 connected from front F to rear B, and the movable end 61' of the drive mechanism 6 is connected to the curtain 21 of the foremost sunshade component 2. Only the fixed slider 23 of the rearmost sunshade component 2 is fixed to the slide rail 1, while the fixed sliders 23 of the other sunshade components 2 can slide under the drive of the drive mechanism 6. Thus, when the movable end 61' of the drive mechanism 6 moves forward F along the extension direction X, the curtains 21 of the multiple sunshade components 2 can be unfolded in sections. When the movable end 61' of the drive mechanism 6 moves backward B along the extension direction X and cooperates with the winding force of the roller structure 22 of the multiple sunshade components 2, the curtains 21 of the multiple sunshade components 2 can be wound up in sections, thereby achieving the sunroof shading and use. Compared with the prior art, the diameter of the curtains 21 of the multiple sunshade components 2 in the wound state is smaller in the present invention. Therefore, the space occupied by the sunshade assembly of the present invention in the height direction Z of the vehicle body is significantly reduced.

[0044] The working process of the sunshade assembly includes:

[0045] Unfolding process: The movable end 61' of the drive mechanism 6 moves forward, and the curtain 21 of the first sunshade assembly 2' is fully unfolded under the pull of the movable end 61'. Then, the fixed slider 23 of the first sunshade assembly 2' slides forward F and pulls the curtain 21 of the sunshade assembly 2 behind it to fully unfold, until the curtain 21 of the last sunshade assembly 2' is also fully unfolded under the pull of the sunshade assembly 2 in front of it, so that the sunroof of the car can be completely covered by the curtains 21 of multiple sunshade assemblies 2.

[0046] Roll-up process: The movable end 61' of the drive mechanism 6 moves backward, and the curtain 21 of the first sunshade assembly 2' gradually loses the tension of the movable end 61' and is fully rolled up under the rolling force of the corresponding roller structure 22. Then, the fixed slider 23 of the first sunshade assembly 2 slides backward B, and the curtain 21 of the sunshade assembly 2 behind it gradually loses the tension of the first sunshade assembly 2' and is fully rolled up under the rolling force of its roller structure 22, until the curtain 21 of the last sunshade assembly 2 gradually loses the tension of the sunshade assembly 2 in front of it and is also fully rolled up, so that the sunroof of the car can be fully exposed.

[0047] like Figure 2 and Figure 3 As shown, in an embodiment of the present invention, in order to ensure that the curtains 21 in the multiple sunshade curtain assemblies 2 can be unfolded one by one from front to back and rolled up one by one from back to front, the embodiment of the present invention controls the rolling force of the roller structure 22 in each sunshade curtain assembly 2, thereby achieving orderly unfolding and orderly rolling up of the curtains in each sunshade curtain assembly 2.

[0048] The curtain 21 has an initial unfolding state and an end unfolding state. In the initial unfolding state, the curtain 21 is subjected to the initial winding force provided by the corresponding roller structure 22. In the end unfolding state, the curtain 21 is subjected to the end winding force provided by the corresponding roller structure 22. During the unfolding process of the curtain 21 of two adjacent sunshade curtain assemblies 2, the end winding force of the curtain 21 of the preceding sunshade curtain assembly 2 is less than the initial winding force of the curtain 21 of the following sunshade curtain assembly 2.

[0049] During the unfolding process of the curtain 21 in a sunshade assembly 2, the drive mechanism 6 needs to overcome the winding force on the curtain 21 to pull the curtain 21 unfold. That is to say, the smaller the winding force on the curtain 21, the easier it is to be pulled unfolded by the drive mechanism 6, and the more difficult it is to roll up under the action of the winding force when the tension is lost; the greater the winding force on the curtain 21, the more difficult it is to be pulled unfolded by the drive mechanism 6, and the more easy it is to roll up under the action of the winding force when the tension is lost. Therefore, the present invention controls the winding force provided by the roller structure 22 of multiple sunshade assemblies 2, so that the curtain 21 of the sunshade assembly 2 arranged further forward is easier to unfold and more difficult to roll up, and the curtain 21 of the sunshade assembly 2 arranged further back is more difficult to unfold and easier to roll up. Furthermore, by controlling the final winding force on the curtain 21 of the preceding sunshade assembly 2 to be less than the initial winding force on the curtain 21 of the following sunshade assembly 2, when unfolding, the curtain 21 of the preceding sunshade assembly 2 is fully unfolded before the curtain 21 of the following sunshade assembly 2 unfolds. Similarly, when winding, the curtain 21 of the following sunshade assembly 2 experiences a greater winding force and can complete winding first before the curtain 21 of the preceding sunshade assembly 2 is wound up. This allows the curtains 21 of multiple sunshade assemblies 2 to unfold one by one from front to back and to wind up one by one from back to front.

[0050] Specifically, taking four sunshade components 2 as an example, the following explanation is provided: When the curtain 21 of the first sunshade component 2' is fully unfolded, the final roll-up force it experiences is less than the initial roll-up force experienced by the curtain 21 of the second sunshade component 2 when it begins to unfold under the pull of the first sunshade component 2; similarly, when the curtain 21 of the second sunshade component 2 is fully unfolded, the final roll-up force it experiences is less than the initial roll-up force experienced by the third sunshade component 2 when it begins to unfold under the pull of the second sunshade component 2; similarly, when the third sunshade component 2 is fully unfolded, the final roll-up force it experiences is less than the initial roll-up force experienced by the last sunshade component 2" when it begins to unfold under the pull of the third sunshade component 2.

[0051] Among them, between two adjacent sunshade curtain assemblies 2, the front end of the curtain 21 of the latter sunshade curtain assembly 2 can be directly or indirectly connected to the fixed slider 23 of the former sunshade curtain assembly 2, so that when the curtain 21 of the former sunshade curtain assembly 2 can no longer unfold, it can pull the fixed slider 23 to slide through its roller structure 22, thereby unfolding the curtain 21 of the latter sunshade curtain assembly 2 under the pull of the fixed slider 23 of the former sunshade curtain assembly 2.

[0052] like Figure 2 As shown, in an embodiment of the present invention, the drive mechanism 6 includes a motor 62, a drive connecting strip 61, and two drive flexible shafts 63. The drive connecting strip 61 is arranged in front of the first sunshade assembly 2' and connected to the curtain 21 of the first sunshade assembly 2. One end of the two drive flexible shafts 63 is connected to both ends of the drive connecting strip 61 through two flexible shaft sliders 64 and slides with the two slide rails 1 along the extension direction X. The motor 62 drives the two drive flexible shafts 63 to move relative to each other, thereby causing the two flexible shaft sliders 64 to slide synchronously along the extension direction X.

[0053] Specifically, the sunshade assembly also includes a front crossbeam 8 and a rear crossbeam 7. The front ends of the two slide rails 1 are fixed to both ends of the front crossbeam 8, and the rear ends of the two slide rails 1 are fixed to both ends of the rear crossbeam 7. The motor 62 is mounted on the front crossbeam 8. Parts of the two drive flexible shafts 63 are laid on the front crossbeam 8 and connected to the motor 62. The specific structure of the connection between the motor 62 and the two drive flexible shafts 63, as well as the specific working principle of the motor 62 driving the two drive flexible shafts 63, are the same as in the prior art and will not be described again here. Figure 3 and Figure 4 As shown, the drive connecting strip 61 is provided with a third slot 612, and the front end of the curtain 21 of the first sunshade assembly 2' is secured in the third slot 612 by a third support member 611. One end of the flexible shaft slider 66 is connected to the slide groove 11 of the slide rail 1 (see... Figure 6 The flexible shaft slider 64 has a connecting protrusion 641 at one end and a drive connecting strip 61 has a socket 613 at both ends for engaging with the connecting protrusion 641 of the two flexible shaft sliders 64. The flexible shaft slider 64 is a rubber-coated slider.

[0054] It should be noted that the number of sunshade components 2 is not specifically limited, but is set according to the dimensional limitations of the sunshade assembly in the height direction Z. When used with a skylight of the same length, the more sunshade components 2 there are, the smaller the dimensional size of the sunshade assembly in the height direction Z; conversely, the fewer sunshade components 2 there are, the larger the dimensional size of the sunshade assembly in the height direction Z. In embodiments of the present invention, the number of sunshade components 2 is preferably 2 to 5. In an embodiment of the present invention, the number of sunshade components 2 is 4.

[0055] like Figure 5As shown, in one embodiment of the present invention, between two adjacent sunshade curtain assemblies 2, the fixed slider 23 of the preceding sunshade curtain assembly 2 is connected to the front end of the curtain fabric 21 of the following sunshade curtain assembly 2 via a curtain connecting strip 3. Both ends of the curtain connecting strip 3 are fixed to the two fixed sliders 23 of the preceding sunshade curtain assembly 2, allowing the two fixed sliders 23 of the preceding sunshade curtain assembly 2 to pull the curtain fabric 21 of the following sunshade curtain assembly 2 open via the curtain connecting strip 3. A guide strip 4 can also be provided in front of each sunshade curtain assembly 2, with both ends fixed to the two fixed sliders 23 of the adjacent sunshade curtain assembly 2 behind it. The curtain fabric 21 of the first sunshade curtain assembly 2' is connected to the movable end 61' under the guidance of the guide strip 4 in front of it, allowing for smoother opening and closing of the curtain fabric 21 of the first sunshade curtain assembly 2'. The curtain 21 of the adjacent sunshade assembly 2 at the rear is connected to the curtain 3 in front of it under the guidance of the corresponding guide strip 4, so that the unfolding and rolling up of the curtain 21 of the rear sunshade assembly 2 can be smoother.

[0056] Specifically, the curtain connecting strip 3 is provided with a first slot 32, and the curtain 21 of the subsequent sunshade assembly 2 is secured in the first slot 32 by a first support member 31. The opening of the first slot 32 is generally forward-facing F to prevent the first support member 31 from dislodging from the first slot 32 when the curtain connecting strip 3 is pulled on the curtain 21 of the subsequent sunshade assembly 2. An entrance / exit is formed between the guide strip 4 at the front of the preceding sunshade assembly 2 and the curtain connecting strip 3 at the rear. The front end of the curtain 21 of the preceding sunshade assembly 2 can extend out of this entrance / exit, and the front end of the curtain 21 of the subsequent sunshade assembly 2 can extend into the entrance / exit and be secured in the first slot 32 by the first support member 31. The first support member 31 can be made of steel wire, and the front end of the curtain 21 is wrapped around the steel wire and sewn in place. The first support member 31 can also adopt other structures. The curtain 21 of the rear sunshade assembly 2 can also be connected to the curtain connecting strip 3 in front of it by other fixing methods.

[0057] Taking four sunshade components 2 as an example, the following is a detailed explanation: The first three sunshade components 2 each have a guide strip 4 fixed to the oblique front of their respective roller structure 22 by their two fixed sliders 23, and a curtain connecting strip 3 fixed to the oblique rear of their roller structure 22; the last sunshade component 2 can have a guide strip 4 fixed only to the oblique front of its roller structure 22 by its two fixed sliders 23. Since the guide strip 4 and the curtain connecting strip 3 only occupy a portion of the space below the roller 21 in the height direction Z and not above the roller 21, it is beneficial to reduce the overall size of the sunshade assembly in the height direction Z.

[0058] Among them, combined Figure 6As shown, the specific structure of the roller structure 22 can be the same as that of the prior art roller structure. For example, it may include a roller 221, a roller tube 222, and a torsion spring. The rear end of the curtain 21 can be fixed to the roller tube 222 by double-sided tape or other fixing methods. The roller 21 passes through the roller tube 222, and both ends of the roller 21 are fixed to two fixed sliders 23. The roller tube 222 is rotatably connected to the roller 221. The torsion spring is sleeved on the roller 221 and its two ends are respectively connected to the roller 221 and the roller tube 222. When the movable end 61' of the drive mechanism 6 moves forward, the curtain 21 is pulled open after being guided by the guide strip 4, and the roller tube 222 drives the torsion spring to rotate relative to the roller 221. When the movable end 61' of the drive mechanism 6 moves backward, the roller tube 222 rotates under the action of the elastic restoring force of the torsion spring and rolls up the curtain 21.

[0059] Specifically, each fixed slider 23 can be provided with an insertion hole 231 that is interference fit with the roller 221 of the roller structure 22 and a slot 232 for installing the guide strip 4 and the curtain connecting strip 3. The slide rail 1 is provided with a slide groove 11 that cooperates with the fixed slider 23. The two inner sides of the slide groove 11 in the height direction Z respectively have a lower limit protrusion 13 and an upper limit protrusion 12. The lower limit protrusion 13 stops inside the fixed slider 23, and the upper limit protrusion 12 cooperates with the limiting groove 233 on the fixed slider 23, thereby realizing the limitation of the fixed slider 23 in the depth direction Y of the slide groove 11 (that is, the width direction of the curtain 21 and the axial direction of the roller structure 22) and preventing it from falling out.

[0060] Combination Figure 7 As shown, in another embodiment of the present invention, between two adjacent sunshade curtain assemblies 2, the fixing slider 23 of the preceding sunshade curtain assembly 2 is connected to the front end of the curtain fabric 21' of the following sunshade curtain assembly 2 via a bushing 5. The bushing 5 is sleeved on the roller structure 22 of the preceding sunshade curtain assembly 2 to roll up the curtain fabric 21 within the bushing 5. The two ends of the bushing 5 are fixed to the two fixing sliders 23 of the preceding sunshade curtain assembly 2. The bushing 5 can simultaneously perform the functions of the guide strip 4 and the curtain connecting strip 3 in the above embodiment. It is integrally formed, has a simple structure, and is easy to install. Specifically, the bushing 5 has an opening 53, and a second slot 52 is provided inside the bushing 5. In the two adjacent sunshade curtain assemblies 2, the front end of the curtain fabric 21 of the preceding sunshade curtain assembly 2 can extend out from the opening 53, and the front end of the curtain fabric 21' of the following sunshade curtain assembly 2 can extend into the opening 53 and be secured in the second slot 52 by the second support member 51. The second support member 51 can be a steel wire.

[0061] Combination Figure 8As shown, in an embodiment of the present invention, the curtain 21 is provided with a locking structure 24. When the curtain 21 of the sunshade assembly 2 is opened to a preset position, the locking structure 24 can cooperate with the component in front of it to prevent the curtain 21 from continuing to unfold. In one embodiment of the present invention, the locking structure 24 cooperates with the guide strip 4 in front of it to prevent the curtain 21 from continuing to unfold. Specifically, the locking structure 24 includes a fourth support member 241 and a pressing plate 242. The pressing plate 242 presses and fixes the fourth support member 241 to the curtain 21. The fourth support member 241 can be a steel wire, and the pressing plate 242 can be an iron sheet. The steel wire is pressed and fixed to the surface of the front side of the curtain 21 by a patch. Figure 7 As shown, in another embodiment of the present invention, the locking structure 24 engages with the front edge of the opening 53 of the bushing 5 in front of it to prevent the curtain 21 from continuing to unfold.

[0063] The present invention also provides a car, including a sunshade assembly. The sunshade assembly in this embodiment has the same specific structure, working principle and beneficial effects as the sunshade assembly in embodiment one, and will not be described again here.

Those skilled in the art can make various modifications or variations to the embodiments of the present invention based on the content disclosed in the application documents without departing from the spirit and scope of the present invention.
