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.

It should be noted that the drawings are not only for the purpose of illustrating and explaining particular embodiments of the invention, but also for the purpose of assisting in the definition of the invention as necessary.

In this specification, "longitudinal" denotes a longitudinal direction of the vehicle, and directional terms such as "front", "rear", "top", and the like are defined according to an actual direction of the vehicle.

A preferred embodiment of the connecting piece according to the invention and of the associated roller blind mechanism and skylight assembly is described below with the aid of fig. 1 to 5.

In this embodiment, the sun blind rolling mechanism includes a roller 2, and the roller 2 is mounted at the rear end of a longitudinal sunroof rail 3 by connecting members 1 connected to both ends thereof. When the rolling mechanism is operated, the rolling shaft 2 can rotate around the central axis of the rolling shaft to drive the curtain to be unfolded and folded. Only the coupling member 1 coupled to one end of the reel 2 is shown in fig. 1 to 5, and the other coupling member coupled to the other end of the reel 2 is arranged symmetrically to the illustrated coupling member 1 with respect to the longitudinal center axis of the vehicle, which are identical in construction and functional principle, and thus the other coupling member is not shown for simplicity of the drawings.

As can be seen with particular reference to fig. 1 and 2, the connection element 1 essentially comprises a support plate 11, a spindle 12, a first mounting portion and a second mounting portion.

The support plate 11 extends in a substantially vertical plane and has an inner surface 111 and an outer surface 112 opposite to each other. Here, the surface oriented toward the inside of the vehicle (i.e., toward the spool 2) is referred to as an inner surface 111, and the surface oriented toward the outside of the vehicle (i.e., toward the rail 3) is referred to as an outer surface 112.

The spindle 12 is provided at a substantially central position of the inner surface 111 of the support plate 11 to be adapted to coaxially connect the reel 2. That is, the spindle 12 protruding from the inner surface 111 of the support plate 11 is inserted into the reel 2 from the end of the reel 2 in a manner similar to a bayonet, so that the reel 2 can only rotate around the spindle 12 and cannot translate in any direction.

To accomplish the securement of the connector to the sunroof rail, the connector typically includes a plurality of mounting portions that are longitudinally spaced apart. In prior art connectors, these mounting portions typically include a plurality of openings through which fasteners pass, such as front and rear openings that open at the front and rear of the connector, respectively, to secure the connector to the sunroof rail via fasteners (e.g., screws) that pass through the openings. However, as mentioned above, although this fixing method can ensure sufficient connection strength, it has disadvantages in that the number of parts of the sun blind rolling mechanism is increased, the installation process is complicated, and cost control is not facilitated.

According to the utility model discloses a design needs to optimize the structure of the installation department of connecting piece 1 as far as possible when guaranteeing sufficient joint strength to in the quick installation of realizing this connecting piece 1, and reduce economic cost.

As shown in fig. 1 to 5, the connector 1 comprises a first mounting portion and a second mounting portion longitudinally spaced from each other, wherein the first mounting portion is similar to the mounting portion of the prior connector in that it extends forwardly from the support plate 11 and is open with a single opening 16 for a fastener to pass through to effect the securement of the front end of the connector 1 by a single fastener (e.g., a screw).

In the illustrated embodiment, the connecting member 1 includes a curtain guide portion 15 extending from the front end of the support panel 11 in the curtain deployment direction, and both the opening 16 of the first mounting portion and a fastener receiving portion 17 (e.g., a screw head receiving portion) surrounding the opening 16 are formed in the curtain guide portion 15, e.g., in the front portion of the curtain guide portion 15. The curtain guide portion 15 functions to cause the curtain unwound from the spool 2 to enter the sun roof rail 3 via the guide surface of the curtain guide portion 15 and move along the sun roof rail 3. Note that the present invention does not limit the shape of the curtain guide 15. In fact, the curtain guide 15 may have any configuration that can achieve the curtain guide function described above.

As can be seen with particular reference to fig. 1 and 2, the second mounting portion of the connector 1 comprises at least one snap provided on the outer surface 112 of the support plate 11 to enable snapping into the sunroof rail 3, thereby enabling the rear end of the connector 1 to be fixed. Preferably, in order to save on the number of parts, the snap is integrally formed with the support plate 11, for example, integrally injection-molded with the support plate 11.

Preferably, the second mounting portion comprises two catches longitudinally spaced from each other and substantially horizontally aligned. For example, in the illustrated embodiment, the second mounting portion comprises a first catch 13 and a second catch 14, the first catch 13 being disposed at a substantially central position of the outer surface 112 of the support plate 11, the second catch 14 being disposed on the outer surface 112 adjacent to the rear edge of the support plate 11 to optimize the rear end fixation of the connector 1. Of course, the second mounting portion may also comprise only a single snap, which has to have a large longitudinal length (for example not less than one third of the longitudinal length of the support plate 11) to ensure sufficient connection strength.

Fig. 3 to 5 schematically show the snap-fit of the connector 1 with the sunroof rail 3. As shown, the sun roof rail 3 itself includes a guide groove 31, and the catches (the first catch 13 and the second catch 14) of the connector 1 are shaped to fit in the guide groove 31 so as to be able to catch in the guide groove 31.

Furthermore, the top wall of the guide groove 31 can be provided with at least one notch adapted to the shape of the catch, and in the illustrated embodiment, a first notch 33 adapted to the shape of the first catch 13 and a second notch 34 adapted to the shape of the second catch 14 are included, and the longitudinal distance between the first notch 33 and the second notch 34 is the same as the longitudinal distance between the first catch 13 and the second catch 14, so that the two catches can be caught in the guide groove 31 via the two notches. After the two catches have been snapped into the guide groove 31, the section 32 of the top wall of the guide groove 31 between the first recess 33 and the second recess 34 can be used as a snap-in section for snap-fitting with the second catch 14.

According to the utility model discloses, can insert in order to realize reel 2 and the pre-connection of connecting piece 1 through two tip with two connecting piece 1's dabber 12 follow reel 2 earlier, then fixed in order to realize connecting piece 1's rear end in the guide slot 31 of sunroof rail 3 is gone into through the buckle card with connecting piece 1's second installation department, and the front end that realizes connecting piece 1 through the mounting (for example, the screw) of the trompil 16 that passes first installation department is fixed at last to accomplish the whole installation of reel 2 on sunroof rail 3.

The technical content and technical features of the present invention have been disclosed above, but it should be understood that various changes and modifications can be made to the concept disclosed above by those skilled in the art under the inventive concept of the present invention, and all fall within the scope of the present invention.

The above description of embodiments is intended to be illustrative, and not restrictive, and the scope of the invention is defined by the appended claims.
