Description

TECHNICAL FIELD

[0001] The present application relates to the field of parts of automobile sunroof, and particularly relates to a wind screen for a vehicle sunroof and a vehicle. BACKGROUND

[0002] At present, a sunroof is usually arranged on the roof of a vehicle to improve ventilation and light adjustment in the vehicle. The sunroof comprises a sunroof glass which can be opened or closed. A sealing strip is arranged on the roof and cooperates with the sunroof glass. After the sunroof glass is closed, the sunroof glass is in sealing engagement with the sealing strip to prevent water leakage.

[0003] In addition, a wind screen assembly is arranged at the sunroof to improve wind noise after the sunroof glass is opened. Generally, the wind screen assembly comprises a wind screen strip, a lower edge strip and a screen cloth connected between the wind screen strip and the lower edge strip. The wind screen strip can be raised or lowered relative to the lower edge strip to unfold or fold up the screen cloth as the sunroof glass is opened or closed.

[0004] However, in the prior art, when the sunroof glass moves forward to close the sunroof, the screen cloth is easily folded forward and clamped between the sunroof glass and the sealing strip, which destroys the sealing engagement between the sunroof glass and the sealing strip and even can cause water leakage of the sunroof. SUMMARY

[0005] To solve the above technical problems, the first aspect of the present application provides a wind screen for a vehicle sunroof, comprising: a screen cloth; a wind screen strip, an upper edge of the screen cloth being connected to the wind screen strip, the wind screen strip being arranged to be raised or lowered to unfold or fold up the screen cloth; and a folding guide assembly, the folding guide assembly comprising a first guide part on the wind screen strip and a second guide part on the screen cloth, the first guide part being configured as a one-way guide part guiding to the rear side; when the wind screen strip is lowered, the second guide part moves towards the rear side under the guidance of the first guide part to push the screen cloth to fold rearward.

[0006] In an embodiment, the first guide part is configured with a bearing part and a blocking part, the blocking part protruding towards the front side relative to the bearing part, the bearing part and the blocking part constituting a guide step. When the wind screen strip is raised, at least part of the second guide part is movably arranged in the guide step, and the bearing part is at the rear side of the second guide part; when the wind screen strip is lowered, the second guide part rotates towards the rear side under the guidance of the bearing part and the blocking part.

[0007] In an embodiment, the blocking part is formed by an edge of the wind screen strip, and the bearing part is configured as a first plate body extending from the edge of the wind screen strip to the rear side of the screen cloth.

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] In this application, the directional term "front" refers to the direction toward the windshield of the vehicle, such as... Figure 2 Or as indicated by the middle arrow C in 3; the directional term "rear" refers to the direction towards the rear windshield of the vehicle (i.e., opposite to the direction "forward"), such as... Figure 2 or Figure 3 As shown by the middle arrow D.

[0027] Figure 1 A wind deflector 1 (hereinafter referred to as wind deflector 1) for a vehicle sunroof is schematically shown according to an embodiment of this application. Figure 3 This schematically illustrates the state of the mesh fabric when folded and gathered. For example... Figure 1 and Figure 3 As shown, the windbreak net 1 includes a mesh fabric 100 and a windbreak strip 200, with the upper edge 101 of the mesh fabric 100 connected to the windbreak strip 200. The windbreak strip 200 can be raised or lowered to unfold or fold the mesh fabric 100. The windbreak net 1 also includes a folding guide assembly 300. Figure 3As shown, the folding guide assembly 300 includes a first guide 310 on the weather strip 200 and a second guide 320 on the screen cloth 100, the first guide 310 being configured as a one-way guide for guiding toward the rear side. When the weather strip 200 is lowered, the second guide 320 is guided by the first guide 310 to move toward the rear side to push the screen cloth 100 to fold toward the rear side.

[0028] According to the weather screen 1 of the present application, by providing the folding guide assembly 300, when the sunroof glass 32 moves toward the weather strip 31 (as shown by arrow C in Figure 2 or Figure 3 ) to close the sunroof, the lowering of the weather strip 200 guides the first guide 310 on the weather strip 200 to move the second guide 320 on the screen cloth 100 toward the rear side, and the second guide 320 pushes the screen cloth 100 toward the rear side, so that the screen cloth 100 is folded toward the rear side (as shown by arrow D in Figure 2 and Figure 3 ). In this way, the folding direction of the screen cloth 100 is opposite to the moving direction of the sunroof glass 32, so that the screen cloth 100 is prevented from being clamped between the sunroof glass 32 and the weather strip 31, and the sealing of the sunroof is ensured. Moreover, in the case of wind blowing forward, the folding guide assembly 300 can also prevent the screen cloth 100 from folding toward the front side, which greatly improves the use experience in actual use.

[0029] The specific structure of the first guide 310 and the second guide 320 will be described below.

[0030] As shown in Figure 4 , 6 , 7 and 8, the first guide 310 is configured with a bearing portion 312 and a blocking portion 311. The blocking portion 311 protrudes toward the front side relative to the bearing portion 312 to form the above-mentioned guide step. When the weather strip 200 is raised, at least part of the second guide 320 is movably located in the guide step, and the bearing portion 312 is located at the rear side of the second guide 320. When the weather strip 200 is lowered, the second guide 320 is guided by the bearing portion 312 and the blocking portion 311 to rotate toward the rear side.

[0031] Overall, the guide step forms a space with an opening toward the front side, so that the second guide 320 can be conveniently matched with the guide step. Specifically, as shown in Figure 8As shown, when the wind barrier 200 is raised (i.e. when the screen cloth 100 is unfolded), at least a portion of the second guide 320 (e.g. the upper portion 321 of the second guide 320) is in the guide step, i.e. at least a portion of the second guide 320 is in front of the bearing portion 312 and the edge of the upper portion 321 abuts against the blocking portion 311. When the wind barrier 200 is lowered (i.e. when the screen cloth 100 is folded), the screen cloth 100 relaxes, the blocking portion 311 pushes the second guide 320 downwards, so that the second guide 320 rotates in compliance with the relaxation of the screen cloth 100; at the same time, the bearing portion 312 at the rear side of the second guide 320 guides the second guide 320 to rotate rearward, so that under the joint action of the screen cloth 100, the blocking portion 311 and the bearing portion 312, the second guide 320 rotates as a whole rearward (as shown by arrow E in the middle), and in turn pushes the screen cloth 100 to fold rearward. In this way, the folding direction of the screen cloth 100 is opposite to the movement direction of the sunroof glass 32, so that the screen cloth 100 is prevented from being clamped between the sunroof glass 32 and the sealing strip 31, and the sunroof maintains good sealing performance. Figure 8

[0032] It should be understood that the wind barrier 200 is provided with a support rod 201 at each end. The support rod 201 is connected to a driving device (not shown in the figure) on the vehicle. When the sunroof glass 32 is opened or closed, the driving device moves synchronously to drive the support rod 201 and the wind barrier 200 to rise or lower. This is well known to those skilled in the art, and will not be described here.

[0033] In the width direction of the screen cloth 100, the extension length of the bearing portion 312 is between 3 mm and 5 mm. According to this structure, the contact area between the bearing portion 312 and the upper portion 321 of the second guide 320 is very small. When the wind barrier 200 is lowered, the second guide 320 is easily separated from the bearing portion 312, so that the second guide 320 rotates as a whole rearward, which greatly reduces or even eliminates the situation that the second guide 320 is stuck in the guide step, and the folding process of the screen cloth 100 is therefore very smooth.

[0034] In a specific embodiment, as shown in Figs. Figure 4 7 and 8, the blocking portion 311 is formed by the edge of the wind barrier 200, and the bearing portion 312 is configured to extend from the edge of the wind barrier 200 to the first plate body at the rear side of the screen cloth 100. In this structure, only very little modification is needed to the wind barrier in the prior art, which greatly reduces the manufacturing difficulty of the windscreen 1 of the present application.

[0035] ​​The surface of the first plate body can be configured as a guide slope inclined to the rear side. In this way, when the wind deflector 200 is lowered, the second guide 320 is easily disengaged from the first plate body (i.e., the bearing portion 312), which also helps to prevent the second guide 320 from being stuck in the guide step, and the folding process of the screen 100 is thus more smooth.

[0036] In another embodiment, the bearing portion 312 can also be configured in other forms. For example, the bearing portion 312 is configured as a plurality of spaced apart comb teeth. When the wind deflector 200 is lowered, these comb teeth can also guide the second guide 320 to rotate as a whole to the rear side.

[0037] Figure 5 The screen 100 with the second guide 320 is schematically shown. As Figure 5 shown, the second guide 320 is configured as a second plate body to facilitate folding the screen 100 to the rear side. The second plate body is disposed close to the upper edge 101 of the screen 100 and corresponds to the guide step. In this way, when the wind deflector 200 is raised, at least part of the second plate body is automatically in the guide step without the need for the user to adjust, thus facilitating the use of the user.

[0038] Also Figure 8 shown, the second plate body includes an upper portion 321 and a main body portion 322 connected to the screen 100. In the width direction of the screen 100, the size of the upper portion 321 is smaller than that of the main body portion 322 (for example, the size of the main body portion 322 is more than 90% of the size of the second plate body). The upper portion 321 is separated from the screen 100. In this way, when the wind deflector 200 is raised, the bearing portion 312 is between the upper portion 321 and the screen 100. In other words, in this case, the bearing portion 312 is supported on the rear side of the upper portion 321 and the blocking portion 311 abuts against the upper edge of the upper portion 321. When the wind deflector 200 is lowered (as Figure 3 shown), the blocking portion 311 pushes the upper portion 321 (or the second plate body) downward, while the bearing portion 312 pushes the upper portion 321 to the front side, so that the main body portion 322 rotates toward the rear side with the lower edge of the bearing portion 312 as the axis. Overall, when the wind deflector 200 is lowered, the main body portion 322 is easily rotated to the rear side, thus pushing the screen 100 to fold to the rear side.

[0039] The ratio of the size of the second plate body to the size of the mesh cloth 100 in the width direction of the mesh cloth 100 is between 1:5 and 1:3. In this way, the size of the second plate body is much smaller than the width size of the mesh cloth 100 after folding. When the mesh cloth 100 is folded, the second plate body does not hinder the folding of the mesh cloth 100, making the folding process of the mesh cloth 100 more smooth. In a specific embodiment, the width of the mesh cloth is 60 mm; the size of the second plate body in the width direction of the mesh cloth 100 is 20 mm, and the size in the length direction of the mesh cloth 100 is 10 mm. Overall, the area of the second plate body is much smaller than the area of the mesh cloth 100, avoiding affecting the overall appearance of the windscreen 1.

[0040] In another embodiment, the second plate body is made of rubber. In this way, the second plate body has appropriate flexibility. When the mesh cloth 100 is relaxed and bent, the second plate body can deform to adapt to the deformation of the mesh cloth 100, which also helps the smooth folding of the mesh cloth 100. In a specific embodiment, the second plate body can be made of EPDM rubber (ethylene propylene diene monomer rubber) or TPV rubber (thermoplastic vulcanized rubber) and the like.

[0041] The second plate body can be integrally formed with the mesh cloth 100 to reduce the assembly steps of the windscreen 1. In another embodiment, the second plate body and the mesh cloth 100 can also be separately formed, but then assembled together. For example, the second plate body is separately formed and then sewn onto the mesh cloth 100. In this way, when either the second plate body or the mesh cloth 100 needs to be maintained, it can be conveniently replaced or maintained separately.

[0042] As shown in the drawings, Figure 5 The number of the second guide 320 is one, and is arranged at the middle of the length direction of the mesh cloth 100. Correspondingly, the number of the first guide 310 is also one, and is arranged at the middle of the length direction of the windscreen strip 200. The inventor found that when the mesh cloth 100 is folded, the second guide 320 pushes the middle part of the mesh cloth 100 to fold to the rear side, and the rest of the mesh cloth 100 is also folded to the rear side under the drive of the middle part, so as to realize the folding of the whole mesh cloth 100 to the rear side.

[0043] In another embodiment, the number of the second guide 320 can be multiple, and is arranged at intervals along the length direction of the mesh cloth 100. Correspondingly, the number of the second guide 320 is also multiple, and is arranged at intervals along the length direction of the windscreen strip 200. In this way, multiple second guides 320 act on the mesh cloth 100 at the same time, which can make the mesh cloth 100 fold to the rear side more effectively; this is especially true when the length of the mesh cloth 100 is longer or the flexibility is greater.

[0044] In addition, for the second guide 320 in the form of a second plate body, it can also be configured as a plate body along the upper edge of the screen cloth 100 and penetrating the screen cloth 100 throughout the length of the screen cloth 100. In this way, it is not necessary to separately provide a plurality of second guides 320 on the screen cloth 100, which greatly simplifies the manufacturing of the windscreen 1. In addition, the windscreen 1 is also more aesthetically pleasing as a whole. It should be understood that in this case, one or more first guides 310 can be provided on the windscreen strip 200 as needed.

[0045] Figure 2 A vehicle 2 according to an embodiment of the present application is schematically shown. As Figure 2 and 3 shown, the vehicle 2 includes a roof 400, on which a sunroof opening 401 is configured; a sunroof frame 402 installed at the sunroof opening 401; and the windscreen 1 according to the above. The sunroof frame 402 includes a front side area 403 at the front side, a rear side area 404 at the rear side, and a mounting bracket 405 between the front side area 403 and the rear side area 404. The windscreen 1 further includes a lower edge strip 406 connected to the lower edge 102 of the screen cloth 100, which is mounted on the mounting bracket 405. When the windscreen strip 200 of the windscreen 1 is lowered, the screen cloth 100 is folded back into the rear side area 404.

[0046] As Figure 3 schematically shown, when the sunroof is closed, the sunroof glass 32 moves forward over the rear side area 404 and abuts against the sealing strip 31 at the front side area 403, while the screen cloth 100 is folded back into the rear side area 404, thereby avoiding the screen cloth 100 being clamped between the sunroof glass 32 and the sealing strip 31, so that the sunroof maintains good sealing.

[0047] The above only describes the embodiments of the present application and is not intended to limit the present application. The present application can have various modifications and changes for those skilled in the art. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the scope of the claims of the present application.
