Fig. 2A to 2C schematically show a part of a vehicle sunroof according to the present invention.

Referring to fig. 2A to 2C, the vehicle sunroof may include a rolling male curtain 101, a rolling male curtain support base 103, and a sunroof rail 107.

The rolling male blind support base 103 may be fixed to the sunroof rail 107 and serves to support the rolling male blind 101. Alternatively, the rolling male curtain support seat 103 may be made of a polymer material and provided with a metal reinforcement 109 to meet both the weight reduction requirement and the mechanical strength requirement. The roller blind support base 103 (including its metal reinforcement 109) may be connected to the metal sunroof rail 107 by a metal connection such as a bolt, stud, or the like. It will be appreciated that the roller blind support base 103 may be a separate component or may be part of a skylight frame for mounting various components.

In some embodiments, as shown in fig. 2A and 5B, a rolling male shade 101 may include a curtain 111, a roller 113, and a mounting assembly 105. The spool 113 may be substantially cylindrical for winding the curtain 111. Both ends of the winding shaft 113 are rotatably mounted to the roller blind mount to rotate relative to the roller blind mount about the longitudinal axis L of the winding shaft 113, thereby facilitating winding and unwinding of the curtain 111. One longitudinal end 114 of the roller 113 may be mounted to a roller blind support 103 on the sunroof side of the vehicle by a mounting assembly 105. As shown in fig. 6A to 6C, the other longitudinal end 118 of the winding shaft 113 may be fixed to the rotary member 106, and the rotary member 106 may be directly mounted to and rotatable relative to the rolling sun blind mount at the other side of the vehicle sunroof. It will be appreciated that the mounting support structure at both ends of the spool 113 may be adjusted depending on the particular construction and desired function of the vehicle sunroof.

In some embodiments, as shown in fig. 5A and 5B, the rolling male shade 101 may further include an elastic member 115. An elastic member 115 may be provided within the spool 113 for restoring the curtain 111. Alternatively, the elastic member 115 may be a torsion spring and extend in the direction of the longitudinal axis L of the spool 113. One longitudinal end 116 of the torsion spring 115 is fixedly mounted to the rolling male blind support block 103 via a mounting assembly 105 (which will be described in further detail below). The other longitudinal end (not shown) of the torsion spring 115 may be fixed to the above-described rotating member 106 to rotate together with the spool 113. Thus, under the action of external force, the curtain cloth 111 can be unfolded and move along the skylight guide rail 107 to partially or completely cover the skylight window, so as to control the light entering the interior of the vehicle, meanwhile, the reel 113 can rotate under the driving of the curtain cloth 111, and the torsion spring 115 can accumulate elastic potential energy when the curtain cloth 111 rotates due to the fact that the longitudinal end 116 is fixed and the other longitudinal end rotates along with the reel 113; after the external force is removed, the torsion spring 115 can release elastic potential energy and drive the winding shaft 113 to rotate, so that the curtain cloth 111 is wound on the winding shaft 113 again, and the automatic reset of the curtain cloth 111 is realized.

Referring to fig. 2A, 3A-3B, and 5B, mounting assembly 105 may include a mounting member 117 and a support member 119. The mounting member 117 is adapted to be connected to the roller blind mount 103 and has a receiving aperture 121 and at least one interference projection (e.g., interference projections 123a, 123b, 123c as shown). The support member 119 has a support portion 125 and an engagement portion 127. The support 125 is adapted to support the spool 113 and allow the spool 113 to rotate relative to the support 125 about the longitudinal axis L of the spool 113. The receiving aperture 121 is configured to allow the engagement portion 127 to be inserted into the receiving aperture 121 to be in an unlocked position (not shown), and to allow the engagement portion 127 to be rotated about the longitudinal axis L of the spool 113 from the unlocked position to the locked position (see fig. 4B). The interference protrusions 123a, 123b, 123c are configured to hinder rotation of the engagement portion 127 about the longitudinal axis L when the engagement portion 127 is in the locked position.

In some embodiments, referring to fig. 2A and 3A, the mounting member 117 includes a mounting body 129 and a connecting portion 131 connected to each other. The mounting member 117 may be made of metal to reduce the occupied space of the mounting assembly while satisfying mechanical strength. The mounting member 117 may be integrated with the roller blind mount 103, for example by means of insert moulding, so that: the connecting portion 131 is embedded in the rolling male curtain support base 103, and the mounting body 129 is located outside the rolling male curtain support base 103 for mounting.

In the illustrated embodiment, the mounting body 129 may be in the form of a plate-like member and extend generally perpendicular to the longitudinal axis L of the spool 113.

The mounting body 129 may include a receiving aperture 121 and interference protrusions 123a, 123b, 123 c. The receiving aperture 121 may have an open portion 133, the open portion 133 allowing the engagement portion 127 of the support member 119 to be inserted into the receiving aperture 121 in a direction generally perpendicular to the longitudinal axis L of the spool 113. In the illustrated embodiment, the interference protrusions 123a, 123b, 123c may be disposed at the perimeter of the receiving aperture 121.

In some embodiments, referring to fig. 2B and 3A, the connection portion 131 may also be in the form of a plate-shaped member and have a substantially L-shaped cross section. The connection portion 131 may be connected to the metal reinforcement 109 by a metal connector such as a bolt, a stud, or the like. The connection portion 131 may be provided with an opening 135 through which a metal connector passes.

The reduction of the space occupied by the mounting member 117 is facilitated by the design of the mounting body 129 and the connecting portion 131 in a plate shape and the embedding of the connecting portion 131 in the rolling male blind supporting base 103. It is understood that the mounting body 129 may have other suitable shapes such as a block.

In some embodiments, referring to fig. 3B and 5B, the support member 119 is generally cylindrical and extends in the direction of the longitudinal axis L of the spool 113. The engagement portion 127 of the support member 119 may be substantially square-cylindrical. Accordingly, referring to fig. 4A and 4B in combination, the receiving aperture 121 of the mounting member 117 may be contoured to allow the engagement portion 127 to be inserted into the receiving aperture 121 via the open portion 133 and to allow the engagement portion 127 to further rotate about the longitudinal axis L of the spool 113 after being inserted into the receiving aperture 121. Specifically, upon installation, the engagement portion 127 of the support member 119 may be first aligned with the open portion 133 of the mounting member 117, and then the engagement portion 127 may be inserted into the receiving aperture 121 via the open portion 133 in a direction substantially perpendicular to the longitudinal axis L of the spool 113, with the engagement portion 127 in the unlocked position; thereafter, the support member 119 is rotated further counterclockwise (with reference to the orientation of fig. 4A and 4B) so that the engagement portion 127 is rotated counterclockwise from the unlocked position beyond the interference protrusion 123B into the locked position shown in fig. 4B. When the engagement portion 127 is in the locked position, the interference protrusions 123a, 123b, 123c are distributed around the engagement portion 127 and are located on a rotational path of the engagement portion 127 about the longitudinal axis L of the spool 113, wherein the interference protrusions 123a, 123c are located on a counterclockwise rotational path of the engagement portion 127 and the interference protrusion 123b is located on a clockwise rotational path of the engagement portion 127, thereby impeding rotation of the support member 119 relative to the mounting member 117 and the male blind mount 103 in both the clockwise and counterclockwise directions. Locking support member 119 in place by rotating support member 119 helps reduce the space required for installation operations.

Referring back to fig. 3B and 5B, the support portion 125 of the support member 119 may be generally cylindrical to support the spool 113 and allow the spool 113 to rotate about the longitudinal axis L of the spool 113 relative to the support portion 125. In particular, the longitudinal end 114 of the reel 113 may be internally sleeved with a bushing 126, the bushing 126 being fixed to the longitudinal end 114 of the reel 113 and supported by the support 125, so that the longitudinal end 114 of the reel 113 and the bushing 126 may rotate together about the longitudinal axis L of the reel 113 with respect to the support 125. A fixing portion 137 is further provided at the support portion 125 for fixing the longitudinal end 116 of the elastic member 115 such that the longitudinal end 116 of the elastic member 115 is fixedly mounted to the rolling male curtain support base 103 via the support member 119 of the mounting assembly 105 without rotating with the rotation of the winding shaft 113. In the illustrated embodiment, the fixing portion 137 is in the form of a through hole to receive and fix the longitudinal end 116 of the elastic member 115.

Referring to fig. 2A and 3B, the support member 119 may also have at least one positioning portion (e.g., the illustrated positioning portions 139a, 139B) disposed adjacent the engagement portion 127 and adapted to abut the mounting body 129 when the engagement portion 127 is in the locked position to define the position of the support member 119 in the direction of the longitudinal axis L of the spool 113. In some embodiments, the support member 119 may have a first detent 139a and a second detent 139 b. The first positioning portion 139a and the second positioning portion 139b may be provided on both sides of the engaging portion 127 in the direction of the longitudinal axis L of the spool 113, respectively, and may sandwich the mounting body 129 therebetween. The first positioning portion 139a is in the form of a lug, and protrudes in a direction perpendicular to the longitudinal axis L of the spool 113. Alternatively, the support member 119 may have two lugs symmetrically disposed. The second positioning portion 139b is in the form of an annular flange, and projects in a direction perpendicular to the longitudinal axis L of the spool 113.

In some embodiments, the mounting member 117 may be made of metal and connected to the sunroof rail 107 via a metal stiffener 109, while the support member 119 may be made of an electrically conductive polymer material such that: on the one hand, the friction between the bearing 125 and the bushing 126 at the longitudinal end 114 of the reel 113 can be reduced compared to a bearing member 119 made of metal; on the other hand, it is allowed that static electricity generated by rolling and unrolling of the curtain cloth 111 and the like can be conducted to the mounting member 117 through the support member 119 and then conducted to the sun roof rail 107 and the vehicle body connected to the sun roof rail 107 via the metal reinforcement 109, thereby avoiding damage of the vehicle sun roof by static electricity. The conductive polymer material of the supporting member 119 may be a composite conductive polymer material formed by filling a polymer matrix (e.g., polyethylene, polypropylene, polystyrene, polyhexamethylene adipamide, epoxy resin, phenolic resin, etc.) with a conductive substance (e.g., carbon black, carbon nanotubes, graphene, carbon fibers, metal oxide, etc.), for example, PA66-CF 20.
