Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

In the present application, the directional phrase "front" refers to a direction toward the front windshield of the vehicle, as indicated by a middle arrow C of fig. 2 or 3; the directional phrase "rear" refers to a direction toward the rear windshield of the vehicle (i.e., opposite to the direction "front"), as indicated by the middle arrow D of fig. 2 or 3.

Fig. 1 schematically shows a wind shielding net 1 for a sunroof of a vehicle (hereinafter, simply referred to as wind shielding net 1) according to an embodiment of the present application. Fig. 3 schematically shows a state in which the mesh cloth is folded and furled. As shown in fig. 1 and 3, the wind screen 1 includes a mesh cloth 100; wind shielding strip 200, upper edge 101 of web 100 is connected to wind shielding strip 200. The weather strip 200 can be raised or lowered to unfold or fold the web 100. The wind screen 1 further comprises a folding guide assembly 300. As shown in fig. 3, the folding guide assembly 300 includes a first guide 310 on the weather strip 200 and a second guide 320 on the web 100, the first guide 310 being configured as a one-way guide that guides to the rear side. As the weather strip 200 descends, the second guide 320 moves toward the rear side under the guide of the first guide 310 to push the web 100 to fold backward.

According to the wind shielding net 1 of the present application, by providing the folding guide assembly 300, when the sun roof glass 32 moves forward toward the sealing strip 31 (as shown by arrow C in fig. 2 or 3) to close the sun roof, the first guide 310 on the wind shielding strip 200 guides the second guide 320 on the net cloth 100 to move to the rear side, and the second guide 320 presses the net cloth 100 to the rear side, thereby folding the net cloth 100 to the rear side (as shown by arrow D in fig. 2 and 3). In this way, the folding direction of the mesh cloth 100 is opposite to the moving direction of the skylight glass 32, so that the mesh cloth 100 is prevented from being clamped between the skylight glass 32 and the sealing strip 31, and the sealing performance of the skylight is ensured. Moreover, the folding guide assembly 300 also prevents the web 100 from being folded toward the front side in the presence of the forward blowing wind, which greatly improves the feeling of use in actual use.

The specific structure of the first guide 310 and the second guide 320 will be seen.

As shown in fig. 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 with respect to the bearing portion 312 to form the guide step. When the weather strip 200 is lifted, at least part of the second guide 320 is movably located in the guide step, and the bearing 312 is located at the rear side of the second guide 320. When the weather strip 200 descends, the second guide 320 rotates toward the rear side under the guide of the bearing portion 312 and the blocking portion 311.

The guide step forms a space with an opening toward the front side as a whole, so that the second guide 320 can be conveniently fitted with the guide step. Specifically, as shown in fig. 8, at least part of the second guide 320 (e.g., the upper portion 321 of the second guide 320) is in the guide step when the weather strip 200 is lifted (i.e., when the web 100 is unfolded), i.e., at least part of the second guide 320 is at the front side of the carrier 312 and the edge of the upper portion 321 abuts against the blocking portion 311. As the weather strip 200 descends (i.e., as the web 100 is folded), the web 100 relaxes, and the blocking portion 311 pushes the second guide 320 downward, so that the second guide 320 rotates in conformity with the relaxation of the web 100; at the same time, the bearing portion 312 at the rear side of the second guide 320 guides the second guide 320 to be rotated backward, so that the second guide 320 is rotated backward as a whole (as indicated by an arrow E in fig. 8) by the combined action of the web 100, the blocking portion 311, and the bearing portion 312, and pushes the web 100 to be folded backward. Thus, the folding direction of the mesh cloth 100 is opposite to the moving direction of the sun roof glass 32, thereby avoiding the mesh cloth 100 from being pinched between the sun roof glass 32 and the weather strip 31, so that the sun roof maintains good sealability.

It should be understood that the wind shielding strips 200 are provided with the struts 201 at both ends thereof, respectively. The strut 201 is connected to a drive means (not shown) on the vehicle. When the sun roof 32 is opened or closed, the driving device moves synchronously to drive the supporting rod 201 and the wind shielding strip 200 to lift or lower. This is well known to those skilled in the art and will not be described in detail here.

The length of the carrier portion 312 extends between 3mm and 5mm in the width direction of the web 100. According to this structure, the contact area between the bearing 312 and the upper portion 321 of the second guide 320 is small. When the weather strip 200 descends, the second guide 320 is easily separated from the bearing part 312, so that the second guide 320 is integrally rotated to the rear side, which greatly reduces or even eliminates the situation that the second guide 320 is caught in the guide step, and thus the folding process of the web 100 is very smooth.

In one particular embodiment, as shown in fig. 4, 7 and 8, the barrier 311 is formed by the edge of the weather strip 200, and the carrier 312 is configured as a first plate extending from the edge of the weather strip 200 to the rear side of the web 100. In this configuration, only very few modifications of the prior art weather strip are required, which greatly reduces the difficulty of manufacturing the wind screen 1 of the present application.

The surface of the first plate body may be configured as a guide slope inclined to the rear side. In this way, the second guide 320 is easily separated from the first plate body (i.e., the bearing part 312) when the weather strip 200 descends, which also helps to prevent the second guide 320 from being caught in the guide step, and thus the folding process of the web 100 is smoother.

In other embodiments, the carrier 312 may be configured in other ways as well. For example, the carrier 312 is configured as a plurality of comb teeth that are spaced apart. These comb teeth may also guide the second guide 320 to rotate toward the rear side as a whole when the weather strip 200 descends.

Fig. 5 schematically shows the web 100 with the second guides 320. As shown in fig. 5, the second guide 320 is configured as a second plate so as to be able to push the web 100 to fold toward the rear side. The second plate is arranged close to the upper edge 101 of the web 100 and corresponds to the guide step. In this way, when the weather strip 200 is lifted, at least part of the second plate body is automatically positioned in the guide step, and adjustment by a user is not required, thereby facilitating the use of the user.

As also shown in fig. 8, the second panel includes an upper portion 321 and a main portion 322 that is connected to the web 100. The size of the upper portion 321 is smaller than the size of the main body portion 322 in the width direction of the web 100 (for example, the main body portion 322 has a size of 90% or more of the size of the second plate). The upper portion 321 is separated from the web 100. Thus, when the weather strip 200 is raised, the carrier 312 is between the upper portion 321 and the web 100. In other words, in this case, the bearing 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 weather strip 200 descends (as shown in fig. 3), 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 toward the front side, so that the body portion 322 rotates toward the rear side about the lower edge of the bearing portion 312. As a whole, when the weather strip 200 descends, the main body portion 322 is easily rotated to the rear side, thereby pushing the mesh cloth 100 to fold backward.

The ratio of the size of the second plate to the size of the web 100 is between 1:5 and 1:3 along the width of the web 100. Thus, the dimensions of the second panel are substantially smaller than the folded width dimensions of the web 100. When the mesh 100 is folded, the second plate body does not obstruct the folding of the mesh 100, so that the folding process of the mesh 100 is smoother. In a specific embodiment, the width of the web is 60mm; the second plate body has a dimension of 20mm in the width direction of the mesh cloth 100 and a dimension of 10mm in the length direction of the mesh cloth 100. The area of the second plate body is much smaller than the area of the mesh cloth 100 as a whole, and the influence on the overall appearance of the wind shielding net 1 is avoided.

In another embodiment, the second plate is made of rubber. In this way, the second plate has a suitable flexibility. The second panel can deform in response to deformation of the web 100 as the web 100 relaxes, bends, which also facilitates smooth folding of the web 100. In a specific embodiment, the second plate body may be made of EPDM rubber (ethylene propylene diene monomer) or TPV rubber (thermoplastic vulcanizate) or the like.

The second panel may be integrally formed with the web 100 to reduce the assembly steps of the wind screen 1. In other embodiments, the second panel and web 100 may be formed separately, yet assembled together. For example, the second panel may be separately formed and then sewn to the web 100. In this way, when either the second panel or the web 100 requires maintenance, it may be easily replaced or maintained individually.

As also shown in fig. 5, the number of second guides 320 is one and is disposed at the middle in the length direction of the web 100. Accordingly, the number of the first guides 310 is also one, and is disposed at the middle of the length direction of the weather strip 200. The inventor has found that when the web 100 is folded, the second guide 320 pushes the middle portion of the web 100 to fold toward the rear side, and the rest of the web 100 is also folded toward the rear side by the middle portion, thereby achieving the folding of the entire web 100 toward the rear side.

In other embodiments, the number of second guides 320 may be multiple and spaced apart along the length of the web 100. Accordingly, the number of the second guides 320 is also plural and is disposed at intervals along the length direction of the weather strip 200. Thus, the plurality of second guides 320 simultaneously act on the web 100, enabling the web 100 to be folded more effectively toward the rear side; this is especially true where the web 100 is longer or more flexible.

In addition, the second guide 320, which is in the form of a second plate, may also be configured as a plate along the upper edge of the web 100 throughout the entire length of the web 100. In this way, there is no need to provide a plurality of second guides 320 separately on the net cloth 100, which greatly simplifies the manufacture of the wind shielding net 1. In addition, the wind screen 1 is also more attractive as a whole. It should be appreciated that in this case, one or more first guides 310 may be provided on the weather strip 200 accordingly as needed.

Fig. 2 schematically shows a vehicle 2 according to an embodiment of the application. As shown in fig. 2 and 3, the vehicle 2 includes a roof 400, and a sunroof opening 401 is configured on the roof 400; a sunroof frame 402 installed at the sunroof opening 401; and a windscreen 1 according to the above. The sunroof frame 402 includes a front side region 403 at the front side, a rear side region 404 at the rear side, and a mount 405 between the front side region 403 and the rear side region 404. The wind screen 1 further includes a lower edge strip 406 attached to the lower edge 102 of the web 100, the lower edge strip 406 being mounted on a mounting frame 405. As the weather strip 200 of the wind screen 1 descends, the mesh sheet 100 is folded toward the rear side and gathered into the rear side region 404.

As schematically shown in fig. 3, when the sunroof is closed, the sunroof glass 32 moves forward over the rear side region 404 and abuts the weather strip 31 at the front side region 403, and the mesh cloth 100 is folded back and folded in the rear side region 404, thereby avoiding the mesh cloth 100 from being sandwiched between the sunroof glass 32 and the weather strip 31, so that the sunroof maintains good sealing.

The foregoing is merely exemplary of the present application and is not intended to limit the present application. Various modifications and variations of the present application will be apparent to those skilled in the art. Any modification, equivalent replacement, improvement, etc. which come within the spirit and principles of the application are to be included in the scope of the claims of the present application.
