Description

Automobile skylight wind screen

Technical Field

The present invention relates generally to the field of automotive skylights, and more particularly to a windshield mesh for an automotive skylight.

Background

At present, when a car skylight is manufactured, a wind screen structure is usually erected on the skylight (especially a panoramic skylight), so that when the skylight is opened, airflow passes through the wind screen and then changes the direction of the airflow flowing through the roof of the car, the airflow is prevented from directly entering a carriage, meanwhile, wind noise caused by the airflow when the car runs at a high speed is reduced, and the riding comfort is improved.

Fig. 1 shows a conventional sunroof wind screen structure, which includes a base member 4', an unfolding member 1', an adjusting device (not shown), and a screen cloth 3'. Wherein the base part 4' is connectable to a vehicle roof part; the deployment element 1 'is pivotably mounted with respect to the base element 4'; the adjustment means pivot the deployment element 1' between the retracted position and the deployed position; and the mesh 3' is arranged between the base part 4' and the unrolling part 1', for example the upper part of the mesh 3' is fixed to the unrolling part 1' by means of fastening means and the lower part of the mesh 3' is also fixed to the base part 4' by means of fastening means. Therefore, the unfolding component 1 'automatically tilts and descends along with the opening and closing of the skylight glass, and the unfolding (supporting and unfolding) and the retraction (winding and shrinking) of the mesh cloth 3' are realized. When the web 3 'is fully expanded, a maximum expanded state is defined and the web 3' is kept in the maximum expanded state by the adjusting device.

The wind screen structure has the following defects: water leakage may occur after the skylight is closed. Since the mesh is typically made of a non-elastic material, the direction of mesh retraction is not controlled when closing the skylight. The mesh may bend outwardly (in the direction of the arrow shown in figure 1) and become trapped by the closed skylight glass, causing a risk of water leakage after the skylight is closed. In addition, because the net cloth does not have a reinforcing piece, the wind noise is increased due to the influence of wind power after the net cloth is used for a period of time, and the wind shielding net is easy to damage.

Detailed Description

The practice and use of the embodiments are discussed in detail below. It should be understood, however, that the specific embodiments discussed are merely illustrative of specific ways to make and use the invention, and do not limit the scope of the invention. The description herein of the structural positions of the respective components, such as the directions of upper, lower, top, bottom, etc., is not absolute, but relative. When the respective components are arranged as shown in the drawings, these direction expressions are appropriate, but when the positions of the respective components in the drawings are changed, these direction expressions are changed accordingly.

Referring to fig. 2 and 3, an automotive sunroof screen according to an embodiment of the present invention is shown. The wind-shielding net comprises a base member, an unfolding member, an adjusting device (not shown) and a net cloth. Wherein the base part can be connected to a vehicle roof part (not shown in the figures) and the deployment part is pivotably mounted with respect to the base part. The base member may be, for example, the front cross member 4 of a skylight, and the deployment member is generally U-shaped. The unrolling part has a crossbar 1 (transverse part) and two longitudinal links 2 (longitudinal part). The transverse bar 1 is fixedly connected at both ends to two longitudinal links 2, and one or both longitudinal links 2 are pivotally connected to the front cross member 4 of the roof window by means of an adjusting device, for example one or two springs on both sides of the wind screen. One or both springs pivot the deployment member to the deployed position when the skylight is open and to the retracted position when the skylight is closed. The mesh 3 is fixedly connected between the cross bar 1 and the front cross member 4 of the windscreen, for example by means of upper and lower fastening members (not shown in the figure). The invention is advantageously provided with spring strips 6 extending in the width direction of the web 3, the spring strips 6 being shown in fig. 2 by way of example at one lateral end of the web 3. It should be understood, however, that at least two elastic sheets are preferably arranged at intervals along the length direction of the web 3, for example, two elastic sheets are respectively arranged at two side ends of the web, or another elastic sheet is additionally arranged at a substantially central position of the web along the length direction, or any other manner selected according to actual needs.

In this embodiment, the substantially U-shaped unrolling part is provided with a transverse part (crossbar 1) and two longitudinal parts (e.g. two longitudinal links 2), which are formed separately during the manufacturing process. However, the substantially U-shaped spreading part may be formed integrally, e.g. by injection moulding, e.g. the transverse bar 1 and the longitudinal links 2 may be formed integrally. Furthermore, the mesh fabric 3 comprises a mesh fabric.

According to the invention, the elastic sheet is used for convexly bending towards the direction opposite to the skylight front cross beam 4 when the mesh cloth 3 is converted into the retraction state from the unfolding state, so that the mesh cloth is driven to retract to prevent being clamped by the skylight glass. The form of the resilient piece includes, but is not limited to, the respective embodiments exemplarily shown in fig. 3 to 6.

Referring first to fig. 3, in some embodiments the resilient tab 6 is attached to the surface of the web 3 opposite the front cross member 4 and is provided with a plurality of half-cuts 62 lengthwise on the surface 61 facing away from the web 3. In this embodiment, the surface 61 where the half cuts 62 are provided is a plane, and the plurality of half cuts 62 are substantially evenly distributed on the plane. The half-cut means incomplete cutting, and the depth of the vertical cut is at least half of the thickness of the elastic piece.

Regardless of the size and specification of the wind screen or mesh 3, the shrapnel 6 preferably substantially completely covers the width of the mesh 3, which for most automotive models may be 8mm to 10mm wide and 4mm to 6mm thick. Accordingly, the slit width of the half slit 62 may be set to 1.5mm to 2mm. When the connecting surface 63 of the elastic sheet 6 is connected with the mesh 3, the elastic sheet 6 and the mesh 3 may be integrally injection-molded in advance, or may be fixedly connected by bonding or sewing at the time of later installation. For the mesh cloth material densely covered with the through holes, the spring plate can be connected with the mesh cloth in an embedding mode. For example, it is conceivable to provide one or more grooves on the connecting surface 63 of the spring plate 6, so that they can engage in the through-holes of the screen cloth.

When the automobile skylight moves from a closed state to an open state, skylight glass (not shown) moves along a guide rail of the skylight under the driving of a motor, the longitudinal connecting rod 2 rotates clockwise under the action of the elastic force of a spring arranged at the axis 5 until the skylight is in a fully opened state (an unfolded position) shown in fig. 3, and the mesh cloth 3 of the wind screen is supported in front of the skylight to play a role in reducing wind noise. When the sunroof moves from the open state to the closed state, the sunroof glass is driven by the motor to move in the opposite direction along the guide rails and pushes the longitudinal link 2 of the windshield net so as to rotate about the axis 5 in the counterclockwise direction in fig. 3, eventually reaching the retracted position. Since the side of the elastic sheet 6 provided with the half cut 62 is made of less material and the side without the half cut is made of more material, the side provided with the half cut 62 is more easily bent, so that in the process of converting the mesh fabric 3 from the unfolding state to the retraction state, the elastic sheet 6 tends to stretch and bend convexly in the direction of the arrow in fig. 3, and further drives the mesh fabric 3 to retract towards the direction opposite to the front cross beam 4 of the sunroof, wherein the direction points to the inner space of the compartment of the automobile. Thereby avoiding the mesh 3 from being clamped by the skylight glass.

In some embodiments, it is preferable that the cut direction of the half cut is set to extend at an angle to the surface of the resilient piece. In the embodiment shown in fig. 4, the spring plate 7 is substantially similar to the spring plate 6 of fig. 3, the surface 71 of which is substantially evenly spaced with half cuts 72 is planar and can be connected to the web by means of a connecting surface 73, with the difference that the half cuts 72 extend at substantially 45 ° to the surface 71. However, the extension angle is not limited to the one shown in the drawing, and may be selected to be 30 ° to 60 °. Fig. 5a to 5b show another embodiment in which the surface 81 of the spring plate 8 provided with the half cut 82 is curved convex, while having the half cut extending at an angle, so that the spring plate 8 has a shape similar to a fish scale structure. The curvature of the curved convex surface improves the unidirectional elastic bending performance, so that in this way the difference in the bending capacity of the material on both sides of the surface 81 and the connecting surface 83 of the spring plate 8 is more pronounced, the surface 81 side being easily bent, and the connecting surface 83 side being hardly bent due to the resistance of the material, so that the purpose of unidirectional convex bending of the web in the direction of the arrow in fig. 5a is easily achieved. It should be understood that, in practical application, the optimal curvature of the arc-shaped convex surface can be selected after testing according to various factors such as the size of the skylight windshield net, the retraction speed of the mesh fabric, even the mesh fabric and the like.

It can also be seen from the embodiment shown in fig. 5a to 5b that the spacing between the half cuts 82 is not exactly the same. The interval of the half-cuts in the middle of the striking plate may be set different from the interval of the half-cuts at both ends of the striking plate, in consideration of the characteristics of different materials of the striking plate. For example, in this embodiment, the pitch of the half notches 82 in the middle of the spring plate 8 is slightly larger than the pitch of the half notches 82 at the two ends of the spring plate 8, and the pitch of the half notches in the middle of the spring plate may range from 5mm to 12mm.

Fig. 6 shows an alternative embodiment in which a spring 9 with elastic return properties can be used. In this embodiment, the spring tabs 9 can be connected not only to the surface of the mesh facing the front cross-member of the skylight, but also to the surface opposite to the front cross-member of the skylight. When the screen cloth is in the state of expansion, shell fragment 9 is in the state of opening, and when the screen cloth changed into the state of contracting from the state of expansion, shell fragment 9 can be along the automatic elasticity of the arrow direction in figure 6 and curl for cyclic annular, and then drive the screen cloth and retract. The elastic properties of the spring 9 should be less than the elasticity of the spring used to raise or lower the windscreen, the spring 9 tending to elastically curl when and only when the windscreen pushes the longitudinal links of the windscreen and rotates them to retract the screen cloth.

In each of the above embodiments, the resilient sheet may be made of a suitable material having certain elastic properties, such as EPDM (ethylene propylene diene monomer) or TPV (thermoplastic vulcanizate), among others. In particular with respect to the embodiment shown in fig. 6, the resilient sheet may also be made of a resilient metal sheet. The elastic sheet arranged according to the invention effectively solves the problem that the mesh cloth is clamped by the wind screen when the skylight wind screen gateway is closed, and the wind strength of the mesh cloth is favorably improved, and the service life of the wind screen is prolonged. The elastic sheet has the advantages of simple structure and convenience in processing, is only slightly protruded out of the surface of the mesh after being connected and fixed with the wind screen, does not influence the attractiveness of a finished product, is easy to implement into skylight wind screen structures of various automobile models, and is wide in application.

When an element is referred to as being "connected" or "coupled" to another element, it can be directly connected or coupled to the other element or intervening elements may be present. In contrast, when an element is referred to as being "directly connected" or "directly coupled" to another element, there are no intervening elements present.

While the technical content and the technical features of the invention have been disclosed, it is understood that various changes and modifications of the disclosed concept can be made by those skilled in the art within the spirit of the invention, and the invention is not limited thereto.
