Description

Technical Field

[0001] The present invention generally relates to a shading device for a frameless vehicle door. Background Art

[0002] With the development of the automobile industry and users' aesthetic and personalized requirements for vehicle appearance, some cars on the market are now equipped with frameless doors, which are loved by some users due to their fashionable appearance.

[0003] Unlike cars with framed doors, cars with frameless doors have many different structural designs because they do not have door frames. In cars with frameless doors, the window glass is sealed with the sealing strip in the body frame after moving to the highest point, so the matching accuracy of the seal is required to be higher.

[0004] In addition, in some cars equipped with framed doors, the shading device is installed in the pillar of the door frame, while there is no pillar on the frameless door. Therefore, in some existing cars equipped with frameless doors, a cloth curtain is installed at the upper edge of the body frame for sunshade. However, such a cloth curtain will reduce the fashion sense of the vehicle in terms of appearance.

[0005] Therefore, there is a need for further improvement of the shading device for frameless vehicle doors. Summary of the invention

[0006] The object of the present invention is to overcome at least one defect of the above-mentioned prior art and to provide a shading device for a frameless vehicle door, by means of which the shading effect of the frameless vehicle door glass can be achieved in a simple structure and space-saving manner.

[0007] To this end, according to one aspect of the present invention, a shading device for a frameless vehicle door is provided, the shading device comprising: a shading curtain, the shading curtain comprising a shading curtain housing and a shading layer, the shading curtain being able to move between a first position and a second position in a vertical direction, in the first position the shading curtain is lowered to a lowest point so as to be stored in the vehicle door, and in the second position the shading curtain is raised to a highest point so as to be completely extended out of the vehicle door. With the shading device, the shading function of the frameless vehicle door glass can be realized in a simple structure and compact space manner, while obtaining a beautiful and fashionable visual effect.

[0008] In a specific embodiment, the shading device further comprises: a traction device connected to the shading layer and configured to traction the shading layer; and a guide rail, wherein the traction component is connected to a sliding guide in the guide rail and is used to unfold and / or retract the shading layer. Thus, the shading function of the frameless door glass can be realized in a particularly reliable manner.

[0009] In a specific embodiment, the pulling device is configured to pull the shading layer from an invalid storage state to an effective unfolded state. Thus, the shading curtain can be stretched in a transverse direction (a direction perpendicular to the lifting direction of the shading curtain, especially a direction parallel to the notch of the vehicle window glass), thereby achieving particularly flexible use freedom and providing more convenient shading adjustability.

[0010] In a specific embodiment, the blackout curtain can be moved between the first position and the second position by means of a motor, thereby realizing electric lifting of the blackout curtain and facilitating the use of the blackout curtain.

[0011] In a specific embodiment, the traction device includes a traction chute and a traction slider, the traction slider can move in the traction chute, the traction device is fixedly connected to the shading layer by means of the traction chute, and the traction device is connected to the sliding guide by means of the traction slider. Thus, a simple structure can be used to provide guidance for the vertical lifting of the blackout curtain and the lateral stretching of the blackout layer, ensuring reliable operation.

[0012] In a specific embodiment, a stopper for the traction slider is provided at the lower end of the traction chute. Preferably, the traction chute is provided with a stopper for the traction slider at both ends. In this way, different types of blackout curtains can be adapted in a simple manner, and at the same time, the size setting of the traction device does not need to extend over the entire height range of the blackout curtain, so that the blackout curtain is completely stored in the vehicle door in the first position and completely extended out of the vehicle door in the second position.

[0013] In a specific embodiment, the traction slider and the sliding guide constitute a slide guide mechanism, thereby being able to more flexibly adapt to the lifting stroke of the blackout curtain.

[0014] In a specific embodiment, the traction chute and the traction slider form a first clamping structure, so that the traction slider can only move in the traction chute in the vertical direction. Preferably, the traction chute has a C-shaped profile, and the traction slider has a T-shaped or I-shaped profile. In this way, particularly reliable vertical guidance can be achieved.

[0015] In a specific embodiment, the guide rail and the sliding guide form a second clamping structure, thereby making it possible to particularly reliably realize the unfolding and retracting of the light shielding layer without the sliding guide accidentally falling off the guide rail.

[0016] In a specific embodiment, the blackout curtain has a rear deflection structure, which has a deflection rod, one end of which is hingedly connected to the traction device and the other end of which is fixedly connected to the additional blackout layer. As a result, the area of ​​the blackout layer can be further expanded at the end region of the blackout layer when necessary.

[0017] In summary, the shading device for a frameless vehicle door according to the present invention provides a shading function for a frameless vehicle door in a simple and cost-effective manner. At the same time, the shading device for a frameless vehicle door according to the present invention has a beautiful visual effect. Advantageously, the design concept of the present invention realizes the lateral stretching application of the shading device for a frameless vehicle door, providing a particularly flexible degree of freedom of use under the premise of compact space and reliable structure.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. Specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can be implemented in a variety of other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0028] It should be noted that the singular form in this article also includes the plural form, unless otherwise specifically mentioned in the wording. Moreover, the meaning of the components, steps, operations and elements involved in "including" or "comprising" used in this article is that at least one other component, step, operation and element may exist or be added. The terms "first", "second" and the like appearing in this article are only for the convenience of description and distinction between different components with the same name, and do not indicate the order or primary and secondary relationship of the relevant components.

[0029] Figure 1 A schematically simplified side view of a vehicle door equipped with a shading device 100 according to one embodiment of the present invention is shown, wherein the sunshade curtain 10 is in a second position completely extended from the vehicle door; Figure 2 A schematically simplified side view of a vehicle door equipped with a shading device 100 according to one embodiment of the present invention is shown, wherein the shading curtain 10 is in a first position stored in the vehicle door; Figure 3 Shown along Figure 2 Schematic cross-section of line AA.

[0030] The shading device 100 of the present invention is particularly provided for a frameless vehicle door. The shading device 100 comprises a blackout curtain 10. The blackout curtain 10 comprises a blackout curtain housing 12 and a blackout layer 14. Preferably, the blackout layer 14 is retractably accommodated in the blackout curtain housing 12. The blackout curtain 10 (comprising the blackout curtain housing 12 and the blackout layer 14) can move between a first position and a second position in a vertical direction.

[0031] like Figure 2 As shown, the blackout curtain 10 is in a first position stored in the vehicle door (especially stored in the vehicle door trim 40). In the first position, the blackout curtain 10 is lowered to the lowest point and stored in the vehicle door, so that the blackout curtain 10 is not visible from the outside of the door. In an exemplary embodiment, in the first position, the blackout curtain 10 is lowered to the lowest point and stored in the vehicle door below the window level H (see, for example, Figure 4 ). Those skilled in the art can clearly understand that, here, the window position H may be a reference line corresponding to the lower window frame edge (or window sill) of the vehicle window.

[0032] like Figure 1As shown, the blackout curtain 10 is in a second position in which it is completely extended from the vehicle door (especially from the vehicle door trim 40), and in the second position, the blackout curtain 10 rises to the highest point and is completely extended from the vehicle door. In an exemplary embodiment, in the second position, the blackout curtain 10 rises to the highest point and is completely extended from the vehicle door above the window level H (see, for example, Figure 5 ).

[0033] Preferably, the shading device 100 further comprises a traction device 20 and a guide rail 30. The traction device 20 is connected to the shading layer 14 (especially fixedly connected to a free end of the shading layer 14) and is configured to traction the shading layer 14. Preferably, the traction device 20 is configured to traction the shading layer 14 (especially transversely) from an invalid storage state to an effective deployment state. The traction device 20 is connected to a sliding guide 32 in the guide rail for deployment and / or folding the shading layer 14. Preferably, the guide rail is arranged along the edge of the vehicle door (especially the upper edge of the vehicle door). Preferably, the guide rail is arranged parallel to the guide groove for the vehicle window glass.

[0034] In a preferred embodiment, the blackout curtain 10 can be moved between a first position and a second position by means of a motor. Thus, the blackout curtain 10 can be electrically lifted and lowered and the use of the blackout curtain 10 is facilitated. Preferably, the blackout curtain 10 is connected to a linear motor to achieve linear movement of the blackout curtain in a vertical direction. Alternatively, the blackout curtain 10 achieves linear movement in a vertical direction by means of a motor and a rack and pinion mechanism. Of course, other embodiments can also be envisioned in which the blackout curtain is moved between a first position and a second position by means of a motor.

[0035] In order to more intuitively present the shading device 100 of the present invention and its use, illustratively, Figure 4 A schematic diagram showing a vehicle door equipped with a shading device according to an embodiment of the present invention, wherein the shading curtain 10 is in a first position stored in the vehicle door; Figure 5 A schematic diagram of a vehicle door equipped with a shading device according to an embodiment of the present invention is shown, wherein the blackout curtain 10 (moved vertically upward) is in a second position fully extended from the vehicle door, and the blackout layer 14 (moved along the guide rail by means of a traction device) is in an unfolded state.

[0036] Figure 6 A perspective view showing a shading device according to a preferred embodiment of the present invention; Figure 7 A top perspective view of a shading device according to a preferred embodiment of the present invention is shown from another viewing angle.

[0037] In a preferred embodiment, the traction device 20 includes a traction chute 22 and a traction slider 24. The traction chute 22 and the traction slider 24 constitute a chute guide mechanism, and the traction slider 24 can be guided and moved in the traction chute 22 (see, for example, Figure 6 and 7 ). As shown in the figure, the traction device 20 is fixedly connected to the shading layer 14 by means of a traction slide 22, and the traction device 20 is connected to the sliding guide 32 by means of a traction slider 24. In a preferred embodiment, the traction device 20 is not only fixedly connected to the shading layer 14, but also can be selectively fixedly connected to the shade housing 12. Preferably, when the shade 10 moves in the vertical direction, the traction device 20 and the shade housing 12 are placed in a fixed connection, so that the traction device 20 can reliably move in the vertical direction with the shade 10, and when the shade 10 is completely extended from the vehicle door, the traction device 20 can be unlocked from the shade housing 12 (disengaged from the fixed connection) so that the traction device 20 can pull the shading layer 14 from the invalid storage state to the effective unfolding state by lateral stretching. Alternatively, it is also conceivable that the traction device 20 is constructed light enough and / or the light shielding layer 14 is constructed rigid enough in the vertical direction, so that when the blackout curtain 10 moves in the vertical direction, the light shielding layer 14 can reliably drive the traction device 20 to move in the vertical direction. Preferably, the traction slider 24 is connected to the sliding guide 32 in a manner that it can freely move relative to the sliding guide 32 in the vertical direction.

[0038] In a preferred embodiment, a stopper (not shown) for the traction slider 24 is provided at the lower end of the traction chute 22. The stopper can limit the vertical movement of the blackout curtain in a simple manner. Of course, the traction chute 22 can also be provided with a stopper for the traction slider 24 at both ends. At the same time, through the size design of the traction chute 22, the traction slider 24 and its stopper, different types of blackout curtains can be adapted in a simple manner. At the same time, the size setting of the traction device 20 does not need to extend over the entire height range of the blackout curtain, so that the blackout curtain is completely stored in the vehicle door in the first position and completely extended out of the vehicle door in the second position.

[0039] Preferably, the stop portion can be integrally formed on the traction chute 22 or the traction slider 24. In particular, the stop portion can be a boss integrally formed on the traction chute 22, thereby achieving a particularly simple structural configuration. Alternatively, the stop portion can be additionally mounted on the traction chute 22 or the traction slider 24. In particular, the stop portion can be additionally clamped to both ends of the traction chute 22. As a result, the position of the stop portion is adjustable. As a result, different stroke limits can be achieved for different models of blackout curtains.

[0040] In a preferred embodiment, the traction slider 24 and the sliding guide 32 form a slide guide mechanism. Figure 6 In the preferred embodiment shown, the traction slider 24 is configured as a slide groove, and the sliding guide 32 is configured as a slider guided in the slide groove, so that the sliding guide 32 is guided in a vertically movable manner in the traction slider 24. Preferably, stoppers for the sliding guide 32 are provided at both ends of the traction slider 24. Thus, the lifting stroke of the blind can be realized more flexibly by adapting the traction slide groove 22 and the traction slider 24 and their stoppers.

[0041] In a preferred embodiment, the traction chute 22 and the traction slider 24 form a first clamping structure, so that the traction slider 24 can only move in the traction chute 22 along the vertical direction. Figure 7 As shown, the traction chute 22 has a C-shaped (cross-sectional) profile, and the traction slider 24 has an I-shaped (cross-sectional) profile. As a result, the traction chute 22 and the traction slider 24 form a clamping structure, so that the traction slider 24 is only guided in the vertical direction in the traction chute 22 and cannot move laterally relative to the traction chute 22. Alternatively, the traction slider 24 can also have a T-shaped (cross-sectional) profile. Of course, other (cross-sectional) profile shapes of the traction chute 22 and the traction slider 24 can also be conceived. As a result, particularly reliable vertical guidance can be achieved.

[0042] In a preferred embodiment, exemplarily as Figure 7 As shown, the guide rail 30 and the sliding guide 32 form a second clamping structure. As a result, the sliding guide 32 can only move along the door edge direction in the guide rail 30, and the sliding guide 32 will not accidentally fall out of the guide rail 30. In an exemplary embodiment, the guide rail 30 has a C-shaped (cross-sectional) profile, and the sliding guide 32 has a T-shaped (cross-sectional) profile. Of course, other (cross-sectional) profile shapes of the guide rail 30 and the sliding guide 32 can also be envisioned. As a result, the unfolding and retracting of the light shielding layer can be particularly reliably achieved.

[0043] In a preferred embodiment, the blackout curtain 10 has a tail deflection structure 60 (see, for example, Figure 5 ). The tail deflection structure 60 has a deflection rod, one end of which is hingedly connected to the traction device 20 and the other end (or the remaining part) is fixedly connected to the additional shading layer. As a result, it is possible to further expand the area of ​​the shading layer at the end area of ​​the shading layer 14 by rotating the tail deflection structure 60 when necessary.

[0044] Refer to the following Figures 6 to 7 The preferred embodiment of the present invention is briefly described below to briefly explain the usage of the shading device 100 for a frameless vehicle door.

[0045] When the shading device needs to be used, the motor is preferably started by a switch, so that the shading curtain 10 is Figure 2 Starting from the first position of the storage in the vehicle door, the window blind 10 moves vertically upward. At the beginning, only the window blind 10 moves upward together with the traction slide 22, and the traction slider 24 in the traction slide 22 is suspended statically on the guide rail 30 (with its upper stop portion) (see schematically). Figure 2 When the shade curtain 10 and the traction slide 22 rise to a certain extent, so that the stopper at the lower end of the traction slide 22 abuts against the traction slider 24, the shade curtain 10 and the traction slide 22 drive the traction slider 24 to move upward together. Until the sliding guide 32 abuts against the stopper at the lower end of the traction slider 24 (see schematically). Figure 1 ), the sunshade curtain 10 reaches the second position where it is completely extended from the vehicle door. At this time, the traction device 20 can be pulled (electrically or manually) (in the case of manual pulling, a traction handle is preferably provided on the outer surface of the traction device) to stretch the sunshade layer 14 transversely to the unfolded state to achieve the required sunshade function.

[0046] When the shading device needs to be retracted, the shading layer 14 is first retracted horizontally to the storage state by the traction device 20 (electrically or manually). Then, preferably, the motor is started by a switch to make the shading curtain 10 move vertically downward together with the traction chute 22. Due to the action of gravity, the traction slider 24 also moves vertically downward together with the shading curtain 10 and the traction chute 22. Until the stopper at the upper end of the traction slider 24 abuts against the sliding guide 32, the traction slider 24 is then suspended on the guide rail 30. Only the shading curtain 10 continues to move vertically downward together with the traction chute 22 until the traction slider 24 abuts against the stopper at the upper end of the traction chute 22, and the shading curtain 10 is in the first position stored in the vehicle door and stops moving. In the case where there is no stopper at the upper end of the traction chute 22, when the shading curtain 10 descends to the first position completely stored in the vehicle door, the motor stops working, and the shading curtain is limited and stopped by the motor.

[0047] In summary, the shading device for a frameless vehicle door according to the present invention provides a shading function for the frameless vehicle door in a simple and cost-effective manner. At the same time, the shading device for a frameless vehicle door according to the present invention has a beautiful appearance. Advantageously, the design concept of the present invention realizes the lateral stretching application of the shading device for a frameless vehicle door, providing a particularly flexible degree of freedom of use under the premise of compact space and reliable structure.

[0048] It should be understood that the present invention is not limited to the above description. Without departing from the spirit and scope of the present invention, the present invention can be modified and changed in various ways.
