Description

Technical Field

[0001] The invention relates to a sunshade curtain, in particular to a sunshade curtain which is used for being installed on the side wall of a motor vehicle and can provide sunshade function for the side window of the side wall of the vehicle. Background Art

[0002] In order to provide a sunshade function at the side windows of the side walls of a motor vehicle, sunshades are usually provided on the inner side of the glass plates of the side windows of the side walls of the vehicle. Existing sunshades are generally divided into two categories: manual and electric, each with its own advantages. Generally speaking, the sunshade includes a curtain mechanism, the curtain mechanism includes a curtain reeling shaft and a curtain connected to the curtain reeling shaft, the curtain can be pulled out from the curtain reeling shaft to unfold and fold. When the sunshade is an electric sunshade device, the sunshade further has an electric curtain driving mechanism, the electric curtain driving mechanism is connected to the movable side plate of the curtain of the curtain mechanism, so that it can electrically control the unfolding and folding of the curtain.

[0003] Both the existing manual sunshade and the electric sunshade can be applied to the side windows of motor vehicles to provide sunshade functions. However, in motor vehicles such as SUVs with three rows of seats, due to their long body length, for safety reasons, the body side wall of the vehicle body has a forward-leaning side column (commonly known as the C-pillar) between the rear side window and the middle side window. When the existing sunshade is applied to the rear side window (located between the C-pillar and the D-pillar), if the curtain reel tube is aligned with the forward-leaning side column, after the curtain is unfolded, the bottom edge of the curtain is tilted upward relative to the bottom edge of the rear side window, so that the light outside the vehicle passes through the unshaded portion between the bottom edge of the curtain and the bottom edge of the rear side window, resulting in a low shielding rate of the sunshade and failing to achieve the intended sunshade effect. In order to ensure that the sunshade curtain reaches a predetermined shading rate when unfolded, the bottom edge of the curtain must be flush with the bottom edge of the rear side window. Therefore, the curtain retracting shaft tube of the existing sunshade curtain mechanism is arranged in an upright manner. Even if the curtain retracting shaft tube is arranged at a rear position close to the forward-leaning side pillar, the upper section of the curtain retracting shaft tube still deviates a certain distance behind the forward-leaning side pillar. Since the curtain retracting shaft tube cannot be combined with the forward-leaning side pillar, the curtain mechanism of the sunshade is difficult to be integrated with the structure and equipment of the vehicle body, and there is also a problem of poor aesthetics.

[0065] The following further describes the technical means adopted by the present invention to achieve the predetermined purpose of the invention in conjunction with the accompanying drawings and preferred embodiments of the present invention.

[0066] According to the above-mentioned invention content, the sunshade with a rotation function proposed by the present invention is used to be installed on a side wall of a motor vehicle. Figure 1 , Figure 4 , Figure 7 , Fig.10 and Fig.13As shown, a sunshade function is provided for a rear side window 2 located behind a forward-leaning side pillar 1 in the side wall of the vehicle body. The sunshade mainly includes a curtain mechanism 10 and a rotation mechanism 20. The curtain mechanism 10 includes a curtain retracting shaft tube 11 and a curtain 12. The curtain 12 is arranged on the curtain retracting shaft tube 11 and can be operated to unfold and fold. The rotation mechanism 20 is arranged between the curtain retracting shaft tube 11 and the side wall of the vehicle body, so that the folded position of the curtain mechanism 10 in the folded state is close to the forward-leaning side pillar 1, and the curtain mechanism 10 can be operated to rotate to a normal position of an upright state relative to the forward-leaning side pillar 1 and then unfold the curtain 12 to cover the rear side window 2, providing a larger shielding rate for the rear side window 2.

[0067] Preferably, a folding space 1A is preset inside the forward-tilting side column 1, and the folding space 1A forms openings at the rear side and the bottom end of the forward-tilting side column 1, so that the curtain mechanism 10 can enter and exit the folding space 1A of the forward-tilting side column 1 through the opening of the folding space 1A. When the curtain mechanism 10 is transferred to the folding position, it can be stored in the folding space 1A inside the forward-tilting side column 1, and the curtain mechanism 10 is protected by the forward-tilting side column 1, and can be hidden inside the forward-tilting side column 1 when the curtain mechanism 10 is transferred to the folding position.

[0068] Based on the aforementioned inventive concept, the present invention can at least be as follows: Figure 1 , Figure 4 , Figure 7 , Fig.10 and Fig.13 The sunshade can be a manually operated sunshade device or an electrically operated sunshade device, and each specific feasible preferred embodiment is described below.

[0069] like Figures 1 to 3 The first preferred embodiment shown in the figure discloses that the sunshade is a manually operated sunshade device, and the sunshade includes a cloth curtain mechanism 10 and a rotation mechanism 20. The cloth curtain mechanism 10 includes a cloth curtain retracting shaft tube 11 and a cloth curtain 12. The bottom end of the cloth curtain retracting shaft tube 11 has a connecting portion 13 and a rotating shaft 14 disposed in the connecting portion 13. The rotating shaft 14 can be an independent component; or the rotating shaft 14 and the connecting portion 13 are integrally formed components. The cloth curtain retracting shaft tube 11 is pivotally disposed at the lower part of the rear side window 2 of the side wall of the vehicle body and adjacent to the forward tilting side pillar 1, so that the cloth curtain retracting shaft tube 11 can rotate forward and backward.

[0070] In the curtain mechanism 10, the curtain retractor shaft tube 11 includes a pipe 111 and a curtain retractor 112 disposed inside the pipe 111. The rear side of the pipe 111 has a long hole extending along the length direction. The curtain retractor 112 can be an existing product, and its specific structure is not repeated here. The connecting portion 13 is disposed at the bottom end of the pipe 111. The two different sides of the curtain 12 are respectively a connecting side and a movable side plate 121. The curtain 12 passes through the long hole at the rear side of the tube 111 with the connecting side and extends into the tube 111 of the curtain retracting shaft tube 11 and connects to the curtain retractor 112, so that the curtain 12 can be automatically retracted by the curtain retractor 112 of the curtain retracting shaft tube 11. The movable side plate 121 of the curtain 12 is located outside the tube 111 of the curtain retracting shaft tube 11, and the curtain 12 can be pulled out from the curtain retracting shaft tube 11 and unfolded. When the curtain 12 is in a fully unfolded state, the movable side plate 121 can be fixed at the rear side of the rear side window 2.

[0071] When a folding space 1A is preset inside the tilting side column 1, the lower section of the curtain winding shaft tube 11 passes through the folding space 1A of the tilting side column 1 and extends out of the bottom end of the tilting side column 1, and the connecting portion 13 at the bottom end of the tube 111 is pivotally mounted on the side wall of the vehicle body below the tilting side column 1, so that the curtain mechanism 10 can enter and exit the folding space 1A in the tilting side column 1 through the opening of the folding space 1A, and when the curtain mechanism 10 is transferred to the folding position, the curtain mechanism 10 can be stored in the folding space 1A inside the tilting side column 1, so that the curtain mechanism 10 is hidden inside the tilting side column 1.

[0072] like Figures 1 to 3 As shown, in this preferred embodiment, the curtain mechanism 10 can be manually operated to unfold and fold, and the movable side plate 121 of the curtain 12 is provided with a handle 122, and the handle 122 provides a position for the user to hold and operate, and the curtain mechanism 10 also includes a hanging member 15, which is arranged at the rear side of the rear side window 2, so that the unfolded curtain 12 is connected to the hanging member 15 by the movable side plate 121, and the curtain is maintained in an unfolded state. The movable side plate 121 can also be separated from the hanging member 15, so that the curtain 12 is automatically rolled up by the curtain rolling shaft tube 11 to be in a folded state.

[0073] like Figures 1 to 3In the first preferred embodiment shown in the figure, the transfer mechanism 20 is connected between the curtain mechanism 10 and the side wall of the vehicle body. In this preferred embodiment, the transfer mechanism 20 is installed at the bottom end of the curtain retracting shaft tube 11 of the curtain mechanism 10 and the front tilting side column 1 below the rear side window 2 of the side wall of the vehicle body. The transfer mechanism 20 includes a transfer limiting component 21 and an elastic member 22. The transfer limiting component 21 is installed on the side wall of the vehicle body and is located at the side limit of the connecting portion 13 to limit the angle range of the front and rear deflection of the curtain retracting shaft tube 11. The elastic member 22 The component 22 can provide a restoring elastic force to the curtain winding shaft 11 of the curtain mechanism 10, so that the curtain mechanism 10 can unfold the curtain 12 backward by hand pulling the curtain 12, and the curtain winding shaft 11 can be deflected backward from the side of the forward-leaning side column 1 to a normal position of an upright state. When the curtain 12 is retracted by the curtain winding shaft 11, the restoring elastic force provided by the elastic component 22 can deflect the curtain winding shaft 11 forward and restore it to a retracted position adjacent to the forward-leaning side column 1, or further enable the curtain mechanism 10 to be stored in the retracting space 1A of the forward-leaning side column 1.

[0074] like Figures 1 to 3 In the first preferred embodiment shown, the elastic member 22 can be a torsion spring or a compression spring, and is assembled between the connecting portion 13 and the rotation limiting component 21, and the elastic member 22 provides a forward elastic force to the connecting portion 13 of the curtain winding shaft tube 11; or, the elastic member 22 can also be a tension spring or an elastic strip, and is connected between the upper section of the curtain winding shaft tube 11 and the side wall of the vehicle body.

[0075] like Figure 4 , Figure 7 , Fig.10 and Fig.13 The various preferred embodiments shown all reveal that the sunshade is an electrically operated sunshade device. In addition to including the cloth curtain mechanism 10 and the rotation mechanism 20, the sunshade further includes a track and a cloth curtain driving mechanism 40, so that the sunshade can electrically drive the curtain 12 of the cloth curtain mechanism 10 to unfold and fold.

[0076] like Figure 4 , Figure 7 , Fig.10 and Fig.13 As shown, the curtain mechanism 10 also includes a curtain retracting shaft tube 11 and a curtain 12. The specific structure of the curtain mechanism 10 is as described above and will not be repeated here. Figures 4 to 15As shown, the transfer mechanism 20 is disposed between the curtain retracting shaft tube 11 and the vehicle body side wall, so that the curtain mechanism 10 can approach the forward tilting side pillar 1 in the folded state, or further the curtain mechanism 10 can be stored in the folding space 1A of the forward tilting side pillar 1, and the curtain mechanism 10 can be operated to transfer to an upright state relative to the forward tilting side pillar 1 and unfold the curtain 12 to cover the rear side window 2. The transfer mechanism 20 changes in accordance with the combination of the curtain driving mechanism 40 and the curtain mechanism 10, and the specific structure of the transfer mechanism 20 is described in detail below.

[0077] like Figure 4 , Figure 7 , Fig.10 and Fig.13 As shown, the track 30 is used to be installed on the top of the side wall body of the vehicle body below the rear side window 2, and the track 30 has a track groove with an opening facing upward. In the above, the track 30 can be sunk into the top of the side wall body, and only the opening at the upper end of the track groove of the track 30 is exposed on the top surface of the side wall body. Alternatively, the track 30 can also be installed on the top surface of the side wall body, so that the track 30 is exposed on the top of the side wall body.

[0078] like Figures 4 to 15 As shown, the curtain driving mechanism 40 includes a driving arm 41 and an electric driving component 42. The bottom end of the driving arm 41 is arranged in the track 30 and can move along the track 30. The upper end of the driving arm 41 is connected to the movable side plate 121 of the curtain 12. The electric driving component 42 is installed inside the side wall of the vehicle body and connected to the driving arm 41. The electric driving component 42 is electrically connected to an in-vehicle control system or control switch provided in the motor vehicle, or further cooperates with a contact switch or position sensing element provided in the side wall of the vehicle body for position detection and control (not shown), so that the electric driving component 42 can be controlled to automatically drive the driving arm 41 to move along the track 30, and drive the curtain 12 of the curtain mechanism 10 to unfold and fold through the driving arm 41.

[0079] like Figures 4 to 15 As shown, in the above, the electric drive component 42 includes a motor gear box group 421 and a flexible drive bar 422. The motor gear box group 421 is electrically connected to the in-vehicle control system of the motor vehicle. The drive bar 422 is connected to the motor gear box group 421 and extends into the track 30 to connect to the bottom end of the drive arm 41. The motor gear box group 421 can be controlled to drive the drive bar 422 and then drive the drive arm 41 to move along the track 30. The motor gear box group 421 can be selected from existing products, and its specific structure will not be repeated. In addition, the electric drive component 42 can also be replaced by other equivalent drive components. The number of the drive bars 422 can also be increased according to actual usage requirements.

[0080] like Figures 4 to 9 In the various preferred embodiments shown, one end of the driving bar 422 driven by the motor gear box assembly 421 extends from the front end 31 of the track 30 and connects to the bottom end of the driving arm 41, or as Figures 10 to 15 In the various preferred embodiments shown, the driving bar 422 driven by the motor gearbox assembly 421 extends from the rear end 32 of the track 30 and connects to the bottom end of the driving arm 41, and the motor gearbox assembly 421 can drive the driving bar 422 to push the driving arm 41 backward to pull the curtain 12 of the curtain mechanism 10 to unfold, and generate a force to pull the curtain retracting shaft tube 11 of the curtain mechanism 10 backward through the curtain 12, so that the curtain retracting shaft tube 11 automatically deflects backward. In addition, the motor gearbox assembly 421 can drive the driving arm 41 through the driving bar 422 to pull the curtain 12 of the curtain mechanism 10 to retract.

[0081] The transfer mechanism 20 changes with the combination of the curtain driving mechanism 40 and the curtain mechanism 10. Figures 4 to 6 The preferred embodiment shown in the figure is a mode in which one end of the driving bar 422 driven by the motor gear box assembly 421 extends from the rear end 32 or the front end 31 of the track 30 and connects to the bottom end of the driving arm 41. The indexing mechanism 20 includes a indexing limiting component 21 and an elastic component 22. The indexing limiting component 21 is installed on the side wall of the vehicle body and is located at the side limit of the connecting portion 13 of the curtain reeling shaft tube 11 to limit the angle range of the front and rear deflection of the curtain reeling shaft tube 11. The elastic component 22 can provide a reset for the curtain reeling shaft tube 11 of the curtain mechanism 10. The elastic force causes the driving arm 41 driven by the electric driving component 42 of the curtain mechanism 10 to pull the curtain 12 to unfold backward, so that the curtain winding shaft tube 11 is deflected backward from the side of the forward tilting side column 1 to a normal position of an upright state.
