Description
1. AREA OF INVENTION
[0001] The present invention relates to a sunshade curtain, in particular a sunshade curtain which is attached to a vehicle side wall in a vehicle for shading a side window of the vehicle side wall. 2. DESCRIPTION OF THE STATE OF THE ART
[0002] To shade a side window on a vehicle's side wall, a conventional sunshade curtain is attached to the inside surface of a door panel mounted on the side window. Conventional sunshades come in two types: manual and electric, each with its own advantages. Generally, the conventional sunshade curtain has a curtain mechanism. This mechanism consists of a retractable tube and a curtain connected to the tube. The curtain can be extended from the tube and retracted into it. Electric sunshades, on the other hand, have an electric drive mechanism. This mechanism is connected to an actuating plate on the side of the curtain to extend and retract it electrically.
[0003] Both manual and electric sunshades are attached to the side window of the vehicle for shading. However, a three-row sport utility vehicle has a relatively long body. For safety reasons, the three-row SUV has a front side pillar (commonly referred to as the C-pillar) located between a rear side window and a center side window. The conventional sunshade is attached to the rear side window (between the C-pillar and a D-pillar). The retractable slat and the front side pillar are positioned side by side. When the shade is extended, the lower edge of the shade is angled upwards relative to the lower edge of the rear side window. Light from outside the three-row sport utility vehicle enters through an unshaded area between the lower edge of the shade and the lower edge of the rear side window.The shading rate of the conventional sunshade curtain is lower, so the intended shading effect is not achieved.
[0004] To achieve the desired level of shading, the bottom edge of the curtain must be flush with the bottom edge of the rear side window. Therefore, the retractable corrugated tube of the conventional sunshade mechanism is mounted vertically. Although the retractable corrugated tube is mounted near the rear of the front side pillar, an upper section of it is still positioned diagonally behind the pillar. The retractable corrugated tube cannot lie directly against the front side pillar. The conventional sunshade mechanism is difficult to integrate into the vehicle's structure and interior, which detracts from its aesthetics.
[0005] To overcome these shortcomings, the present invention provides a sunshade curtain with a translocation function to mitigate or eliminate the aforementioned problems.
[0006] The aim of the invention is to provide a sunshade curtain with a translocation function that can solve the problem that the curtain mechanism of the conventional sunshade curtain cannot be adjacent to the front side pillar of the vehicle side wall when folded.
[0007] The sunshade curtain with a translocation function is installed on a vehicle side wall to shade the inside of a rear side window located behind a front pillar of the vehicle side wall. The sunshade curtain has a curtain mechanism and a translocation mechanism.
[0008] The curtain mechanism consists of a retractable tube and a curtain. The curtain is mounted inside the retractable tube and has an operating side plate that extends from the tube. The curtain can be extended or retracted. The retractable tube has a connecting section and a rotating shaft. The connecting section is attached to one end of the retractable tube. The rotating shaft is mounted on the connecting section. The retractable tube is rotatably mounted below the rear side window, near the front side pillar, via the rotating shaft, allowing it to rotate forward and backward. The curtain can be extended to shade the rear side window.
[0009] The translocation mechanism is located between the retractable tube and the vehicle side panel. When the curtain mechanism is folded, the translocation mechanism ensures that the retractable tube is in a folded position, tilted forward. The folded position is near a side edge of the front pillar. When the curtain mechanism is deployed, the retractable tube can be actuated to deflect it towards the rear of the front pillar into a normal, vertical position.
[0010] With the sunshade curtain structure described above, the sunshade curtain is mounted on the vehicle's side wall to shade the rear side window. When the curtain mechanism is folded, it is deflected forward by the translocation mechanism to a position located on the inside of the front A-pillar, in front of the rear side window. The sliding curtain mechanism is positioned close to the A-pillar to maintain the integrity and aesthetics of the vehicle's interior. When the curtain mechanism is unfolded by the translocation mechanism, it is moved from its forward-tilted position to a vertical position, and then the curtain is extended.A lower edge of the extended curtain lies close to a lower edge of the rear side window to shade the rear side window flush, in order to provide a greater shading rate for the rear side windows and achieve an optimal shading effect.
[0011] The sunshade curtain can also utilize the translocation function created by the curtain mechanism in combination with the front side post, which has a retraction space. When the curtain mechanism is moved into the folded position, it can be retracted into the space provided by the front side post. The curtain mechanism is protected by the front side post. The curtain mechanism is moved into the folded position and is concealed within the front side post.
[0012] The curtain mechanism of the sunshade curtain can be manually operated. The retraction mechanism limits the forward and backward deflection of the retractable tube by means of a limiting section. This limiting section of the mechanism imparts a degree of elasticity to the retractable tube. When a user manually operates the curtain mechanism to extend or retract it, the mechanism automatically adjusts according to the force applied to the curtain. Operating the curtain mechanism is convenient.
[0013] The sunshade curtain also has a track and a drive mechanism. The track is mounted below the rear side window. The drive mechanism consists of a drive arm and an electric drive unit. The lower end of the drive arm is attached to the track. The upper end of the drive arm is connected to an operating side plate of the curtain. The electric drive unit can be activated to power the drive arm, allowing the curtain to be extended or retracted. Therefore, the sunshade curtain can be controlled so that the curtain mechanism is electrically operated for extension or retraction. Alternatively, the curtain mechanism can move automatically when force is applied to it via the relocation mechanism. Operating the curtain mechanism is convenient.

[0014] A sunshade curtain with a translocation function is used for mounting on a vehicle side wall inside a vehicle. Referring to the Fig. 1, Fig. 4, Fig. 7, Fig. 10 and Fig. 13. The sunshade curtain is used to shade a rear side window 2 of the vehicle side wall located behind a front side pillar 1. The sunshade curtain has a curtain mechanism 10 and a translocation mechanism 20. The curtain mechanism 10 has a retractable corrugated tube 11 and a curtain 12. The curtain 12 is mounted in the retractable corrugated tube 11 and can be extended or retracted. The translocation mechanism 20 is located between the retractable corrugated tube 11 and the vehicle side wall. In the folded position, the curtain mechanism 10 is located near the front side pillar 1.The curtain mechanism 10 can be actuated to be moved into a normal position in a vertical state relative to the front side column 1, and then the curtain 12 is extended to shade the rear side window 2 in order to provide the rear side window 2 with a greater shading rate.
[0015] Preferably, the front side column 1 has a retraction chamber 1A formed within it. The front side column 1 has two openings. These two openings are located at the rear and lower ends of the front side column 1 and both connect to the retraction chamber 1A. The curtain mechanism 1 is guided into and out of the retraction chamber 1A of the front side column 1 through the two openings. When the curtain mechanism 10 is moved into the folded position, it can be received into the retraction chamber 1A of the front side column 1. The curtain mechanism 10 is protected by the front side column 1. The curtain mechanism 10 is moved into the folded position and concealed within the front side column 1.
[0016] Based on the aforementioned inventive concept, the sunshade curtain can be realized in several embodiments, referring to the Fig. 1, Fig. 4, Fig. 7, Fig. 10 and Fig. 13. The sunshade curtain can be a manually operated sunshade curtain or an electrically operated sunshade curtain, and each embodiment is described below.
[0017] Referring to the Fig. 1 to Fig. In a first embodiment, the sunshade curtain is manually operated. The sunshade curtain comprises the curtain mechanism 10 and the translocation mechanism 20. The curtain mechanism 10 consists of the retractable corrugated tube 11 and a curtain 12. The retractable corrugated tube 11 has a connecting section 13 and a rotating shaft 14. The connecting section 13 is attached to a lower end of the retractable corrugated tube 11. The rotating shaft 14 is mounted on the connecting section 13. The rotating shaft 14 can be an independent element or it can be formed integrally with the connecting section 13. The retractable corrugated tube 11 is pivotably mounted via the rotating shaft 14 below the rear side window 2 of the vehicle side wall next to the front side pillar 1. The retractable corrugated tube 11 can be rotated forwards and backwards.
[0018] In the curtain mechanism 10, the retractable shaft tube 11 has a body 111 and a curtain winding device 112 mounted in the body 111. The body 111 has an elongated slot formed on its rear side, extending along an axis of the body 111. The curtain winding device 112 can be of conventional design, and its structure is not described in detail. The connecting section 13 is attached to a lower end of the body 111. The curtain 12 has a connecting edge and an actuating side plate 121 opposite the connecting edge. The connecting edge of the curtain 12 passes through the elongated slot of the body 111, is inserted into the body 111 of the retractable shaft tube 11, and is connected to the curtain winding device 112. The curtain 12 can be automatically wound up by the curtain winding device 112 of the retractable shaft tube 11.The actuating side plate 121 of the curtain 12 is located outside the body 111 of the retractable corrugated tube 11 and can be pulled out and extended from the retractable corrugated tube 11. When the curtain 12 is in a fully extended state, the actuating side plate 121 can be attached to the rear of the rear side window 2.
[0019] When the retraction chamber 1A is pre-formed in the front side pillar 1, a lower section of the retractable corrugated tube 11 passes through the retraction chamber 1A of the front side pillar, extends from the lower end of the front side pillar 1, and pivots along the vehicle side wall below the front side pillar 1 by the connecting section 13, which is attached to the lower end of the body 111. The curtain mechanism 10 moves in and out of the retraction chamber 1A of the front side pillar 1 through the two openings in the front side pillar 1. When the curtain mechanism 10 is moved into the folded position, it can be received into the retraction chamber 1A of the front side pillar 1. The curtain mechanism 10 is moved into the folded position and concealed within the front side pillar 1.
[0020] Referring to the Fig. 1 to Fig. 3. The curtain mechanism 10 can be manually operated to extend or retract it. The curtain 12 has a handle 122 attached to the operating side plate 121. The handle 122 allows the user to operate it by hand. The curtain mechanism 10 has a hanging element 15. The hanging element 15 is attached to the rear of the side window. The extended curtain 12 is connected to the hanging element 15 by the operating side plate 121 to hold the curtain 12 in the extended position. The operating side plate 121 can be detached from the hanging element 15, and then the curtain 12 can be automatically rolled into the folded position by the retractable wave tube 11.
[0021] Referring to the Fig. 1 to Fig. In the first embodiment, the translocation mechanism 20 is mounted between the curtain mechanism 10 and the vehicle side wall. The translocation mechanism 20 is attached to the lower end of the retractable corrugated tube 11 of the curtain mechanism 10 and is located below the rear side window 2 of the vehicle side wall, near the front side pillar 1. The translocation mechanism 20 has a limiting section 21 and an elastic element 22. The limiting section 21 is attached to the vehicle side wall and is located on a side edge of the connecting section 13 to limit the angular range of forward and backward deflection of the retractable corrugated tube 11. The elastic element 22 imparts a degree of elasticity to the retractable corrugated tube 11 of the curtain mechanism 10.The retractable corrugated tube 11 is deflected backwards from a side edge of the front side column 1 into its normal, vertical position by a force that pulls the curtain 12 backwards. When the curtain 12 is wound up by the retractable corrugated tube 11, the tube is deflected forwards by the elasticity provided by the elastic element 22 and returned to its folded position next to the front side column 1. The curtain mechanism 10 is then retracted into the retraction space 1A of the front side column 1.
[0022] Referring to the Fig. 1 to Fig. 3. In the first embodiment, the elastic element 22 is a torsion spring or a compression spring and is located between the connecting section 13 and the limiting section 21. The elastic element 22 imparts a forward-directed elasticity to the connecting section 13 of the retractable corrugated tube 11. Alternatively, the elastic element 22 can also be a tension spring or an elastic band and is located between an upper section of the retractable corrugated tube 11 and the vehicle side wall.
[0023] Referring to the Fig. 4, Fig. 7, Fig. 10 and Fig. Figure 13, in several embodiments, is the electrically operated sunshade curtain. The sunshade curtain has not only the curtain mechanism 10 and the translocation mechanism 20, but also a track and a drive mechanism 40. The sunshade curtain can electrically operate the curtain of the curtain mechanism to extend or retract it.
[0024] Referring to the Fig. 4, Fig. 7, Fig. 10 and Fig. 13, the curtain mechanism 10 consists of the retractable wave tube 11 and the curtain 12. The construction of the curtain mechanism 10 is as described above and will not be described again. Referring to the Fig. 4 to Fig. 15, the translocation mechanism 20 is mounted between the retractable shaft tube 11 and the vehicle side wall. The curtain mechanism 10 is located near the front side pillar 1 when folded. The curtain mechanism 10 can also be accommodated in the retraction space 1A of the front side pillar 1. The curtain mechanism 10 can be actuated to move it into its normal, vertical position relative to the front side pillar 1, extending the curtain 12 to shade the rear side window 2. The structure of the translocation mechanism 20 can be modified according to a combination of the drive mechanism 40 and the curtain mechanism 10, as described below.
[0025] Referring to the Fig. 4, Fig. 7, Fig. 10 and Fig. 13. Rail 30 is attached to the vehicle side wall, is located below the rear side window 2, and has a rail groove with an upward-facing opening. Rail 30 can be mounted in an upper section of the vehicle side wall, with only the opening formed in the rail protruding from an upper surface of the vehicle side wall. Alternatively, rail 30 is attached to the top of the vehicle side wall and protrudes from the upper part of the vehicle side wall.
[0026] Referring to the Fig. 4 to Fig. Figure 15 shows that the drive mechanism 40 comprises a drive arm 41 and an electrical drive assembly 42. A lower end of the drive arm 41 is attached to the rail 30 and is movable along the rail 30. An upper end of the drive arm 41 is connected to the actuating side plate 121 of the curtain 12. The electrical drive assembly 42 is mounted in the vehicle side wall, connected to the drive arm 41, and electrically connected to a control system or control switch of the vehicle. Furthermore, the electrical drive assembly 42 can cooperate with a touch switch or a position sensor element in the vehicle side wall to detect and control its position (not shown in the figures). The electrical drive assembly 42 can be controlled to automatically drive the drive arm 41 to move along the rail 30.The curtain 12 of the curtain mechanism 10 is driven by the drive arm 41 to extend or roll up.
[0027] Referring to the Fig. 4 to Fig. 15. The electric drive assembly 42 consists of a motor-gearbox assembly 421 and a flexible drive bar 422. The motor-gearbox assembly 421 is electrically connected to the vehicle's control system. The drive bar 422 is connected to the motor-gearbox assembly 421 and is inserted into the rail 30 to connect the lower end of the drive arm 41. The motor-gearbox assembly 421 is controlled to drive the drive bar 422, thus moving the drive arm 41 along the rail 30. Existing products can be used for the motor-gearbox assembly 421, and its construction is not described. Furthermore, the electric drive assembly 42 can be replaced by other equivalent drive assemblies. The number of drive bars 422 can be increased depending on the actual requirements.
[0028] Referring to the Fig. 4 to Fig. 9, in a second and a third embodiment, one end of the drive bar 422, driven by the motor-gearbox assembly 421, is inserted into a front end 31 of the rail 30 and connected to the lower end of the drive arm 41. Referring to the Fig. 10 to Fig. In the various embodiments, the drive bar 422, driven by the motor-gearbox assembly 421, is inserted into a rear end 32 of the rail 30 and connected to the lower end of the drive arm 41. The motor-gearbox assembly 421 can drive the drive bar 422 to push the drive arm 42 backward and extend the curtain 12 of the curtain mechanism 10. The curtain 12 generates a backward tensile force that is exerted on the retractable shaft tube 11 of the curtain mechanism 10. The retractable shaft tube 11 is automatically deflected backward. The motor-gearbox assembly 421 can drive the drive arm 41 via the drive bar 422 to retract the curtain 12 of the curtain mechanism 10.
[0029] The structure of the translocation mechanism 20 is modified according to the combination of the drive mechanism 40 and the curtain mechanism 10. Referring to the Fig. 4 to Fig. 6, the end of the drive bar 422, driven by the motor-gearbox assembly 421, is inserted into the front end 31 or the rear end 32 of the rail 30 and connected to the lower end of the drive arm 41. The translocation mechanism 20 has a limiting section 21 and an elastic element 22. The limiting section 21 is attached to the vehicle side wall and is located at the side edge of the connecting section 13 to limit the angular range of deflection of the retractable shaft tube 11 forwards and backwards. The elastic element 22 provides the necessary restoring force to the retractable shaft tube 11 of the curtain mechanism 10. The retractable shaft tube 11 is bent back into its normal, vertical position from the side edge of the front side pillar 1 by the force that extends the curtain 12 backwards through the drive arm 41, driven by the electric drive assembly 42.When the curtain 12 is rolled up by the retractable corrugated tube 11, the elasticity of the elastic element 22 deflects the retractable corrugated tube 11 forward and returns it to the folded position next to the front side column 1. Furthermore, the curtain mechanism 10 is retracted into the retraction space 1A of the front column 1. The curtain mechanism 10 is concealed within the front side column 1.
[0030] The end of the drive bar 422 is inserted into the rear end 32 of the rail 30 and is connected to the lower end of the drive arm 41. When the curtain 12 is wound up through the retractable shaft tube 11, the drive arm 41, driven by the drive bar 422, imparts a forward force to the retractable shaft tube 11 through the actuating side plate 121, with the elastic element 22 providing the elasticity. The retractable shaft tube 11 is deflected forward and returned to the folded position near the front side column 1. Simultaneously, the curtain mechanism 10 is retracted into the retraction space 1A of the front side column 1.
[0031] The elastic element 22 is a torsion spring or a compression spring and is located between the connecting section 13 and the limiting section 21. The elastic element 22 imparts forward-directed elasticity to the connecting section 13 of the retractable corrugated tube 11. Alternatively, the elastic element 22 can also be a tension spring or an elastic band and is located between an upper section of the retractable corrugated tube 11 and the vehicle side wall.
[0032] Referring to the Fig. 7 to Fig. In the third embodiment, the end of the drive bar 422, driven by the motor-gearbox assembly 421, is inserted into the front end 31 of the rail 30 and connected to the lower end of the drive arm 41. The translocation mechanism 20 consists of a limiting section 21, a linkage section 23, and a return element 24. The limiting section 21 is mounted on the side wall of the vehicle and is located at the side edge of the connecting section 13 to limit the angular range of the forward and backward deflection of the retractable shaft tube 11. The linkage section 23 is attached to the connecting section 13, extends downward, and has a through-bore 231 formed in a lower section of the linkage section 23. An end of the drive bar 422, located away from the drive arm 41, passes through the through hole 231 of the linkage section 23.The return element 24 is mounted on the drive rail 422 between the front end 31 of the rail 30 and the linkage section 23. The return element 24 pushes the linkage section 23, which is connected to the retractable shaft tube 11, forward to restore the retractable shaft tube 11.
[0033] Referring to the Fig. 7 to Fig. 9, the translocation mechanism 20 also includes an elastic element 22. The elastic element 22 is the torsional spring or the compression spring and is mounted between the connecting section 13 and the limiting section 21. The elastic element 22 imparts a backward elasticity to the connecting section 13 of the retractable shaft tube 11 in order to assistively push the retractable shaft tube 11 backward. Alternatively, the elastic element 22 can provide the connecting section 13 of the retractable shaft tube 11 with a forward elasticity in order to assistively push the retractable shaft tube 11 forward.
[0034] Referring to the Fig. 7 to Fig. 9. When the curtain 12 is extended, the drive bar 422, driven by the motor-gearbox assembly 421, exerts a rearward force on the drive arm 41. The drive arm 41 generates a rearward tensile force on the curtain 12 of the curtain mechanism 10. The forward-tilted retractable shaft tube 11 is deflected rearward from the side edge of the front side column 1. The connecting section 13 of the retractable shaft tube 11 is limited by the limiting section 21. The retractable shaft tube 11 is deflected rearward into its normal position in the vertical state and then ceases to deflect. Then, the drive bar 422, driven by the motor-gearbox assembly 421, drives the drive arm 41 to exert a downward force on the curtain 12 of the curtain mechanism 10.The curtain 12 is pulled out of the retractable corrugated tube 11 and stopped when the actuating side plate 121 of the curtain 12 moves towards the rear of the rear side window 2.
[0035] Referring to the Fig. 7 to Fig. 9. When the curtain 12 of the curtain mechanism 10 is rolled up, the drive bar 422, driven by the motor-gearbox assembly 421, exerts a forward force on the drive arm 41. The drive arm 41 generates a forward tensile force on the curtain 12 of the curtain mechanism 10. Simultaneously, the curtain 12 is automatically rolled up by the retractable shaft tube 11. The drive arm 41 moves forward to a predetermined position at the front end 31 of the track 30. The return element 24, mounted on the drive bar 422, pushes the linkage section 23 connected to the retractable shaft tube 11. The curtain mechanism 10 is deflected forward to return to its normal position. Additionally, the elastic element 22 provides elasticity, and the curtain mechanism 10 is deflected forward and returned to its normal position at the side edge of the front side post 1.Furthermore, the curtain mechanism 10 is taken into the retreat space 1A of the front side column 1 and concealed in the front side column 1.
[0036] Referring to the Fig. 10 to Fig. In a fourth embodiment, the end of the drive rail 422, which passes through the motor-gearbox assembly 421, is inserted into the rear end 32 of the rail 30 and connected to the lower end of the drive arm 41. The translocation mechanism 20 consists of the limiting section 21, a linkage section 23, and a return element 24. The limiting section 21 is attached to the side wall of the vehicle and is located at the side edge of the connecting section 13 of the retractable shaft tube 11 to limit the angular range of the forward and backward deflection of the retractable shaft tube 11. The linkage section 23 is attached to the connecting section 13, extends downward, and has a through-hole 231 formed by the lower section of the linkage section 23. The end of the drive bar 422 furthest from the drive arm 41 passes through the through hole 231 of the linkage section 23.The return element 24 is attached to a distal end of the drive bar 422, which passes through the linkage section 23. The return element 24 presses on the linkage section 23, which is connected to the retractable shaft tube 11. The retractable shaft tube 11 is deflected forward to return to its original position.
[0037] Referring to the Fig. 10 to Fig. 12, the translocation mechanism 20 also includes an elastic element 22. The elastic element 22 is the torsional spring or the compression spring and is mounted between the connecting section 13 and the limiting section 21. The elastic element 22 imparts backward elasticity to the connecting section 13 of the retractable shaft tube 11 to assist in pushing the retractable shaft tube 11 backward. Alternatively, the elastic element 22 can provide forward elasticity to the connecting section 13 of the retractable shaft tube 11 to additionally push the retractable shaft tube 11 forward.
[0038] Referring to the Fig. 10 to Fig. When the curtain 12 is extended, the drive bar 422, driven by the motor-gearbox assembly 421, exerts a rearward force on the drive arm 41. The drive arm 41 generates the rearward pulling force on the curtain 12 of the curtain mechanism 10. The forward-tilted retractable shaft tube 11 is deflected rearward from the side edge of the front side column 1. The connecting section 13 of the retractable shaft tube 11 is limited by the limiting section 21. The retractable shaft tube 11 is deflected rearward into its normal position in the vertical state and then ceases to deflect. Then, the drive bar 422, driven by the motor-gearbox assembly 421, drives the drive arm 41 to exert a downward force on the curtain 12 of the curtain mechanism 10.The curtain 12 is pulled out of the retractable corrugated tube 11 and stopped when the actuating side plate 121 of the curtain 12 moves towards the rear of the rear side window 2.
[0039] Referring to the Fig. 10 to Fig. 12. When the curtain 12 of the curtain mechanism 10 is rolled up, the drive bar 422, driven by the motor-gearbox assembly 421, exerts a forward force on the drive arm 41. The drive arm 41 generates a forward tensile force on the curtain 12 of the curtain mechanism 10. Simultaneously, the curtain 12 is automatically rolled up by the retractable shaft tube 11. The drive arm 41 moves forward to the predetermined position at the front end 31 of the track 30. The return element 24, mounted on the drive bar 422, presses on the linkage section 23 connected to the retractable shaft tube 11. The curtain mechanism 10 is deflected forward to return to its normal position. Additionally, the elastic element 22 provides elasticity, and the curtain mechanism 10 is deflected forward and returned to its normal position at the side edge of the front side post 1.When the front side column 1 has the retraction space 1A, the curtain mechanism 10 is deflected into the folded position, the curtain mechanism 10 is received into the retraction space 1A of the front side column 1 and hidden in the front side column 1.
[0040] Referring to the Fig. 13 to Fig. 15, in a fifth embodiment, the end of the drive rail 422, which passes through the motor-gearbox assembly 421, is inserted into the rear end 32 of the rail 30 and connected to the lower end of the drive arm 41. The translocation mechanism 20 consists of the limiting section 21 and a push rod 25. The limiting section 21 is attached to the vehicle side wall and is located at the side edge of the connecting section 13 of the retractable shaft tube 11 to limit the angular range of forward and rearward deflection of the retractable shaft tube 11. The retractable shaft tube 11 is deflected rearward from the side edge of the front side pillar 1 into its normal, vertical position by the force driving the curtain 12 to extend rearward through the drive arm 41, which is driven by the electric drive assembly 42.The push rod 25 is attached to the lower end of the drive arm 41 and extends forward. As the drive arm 41 moves towards the front end 31 of the rail 30, the push rod 25 pushes the retractable shaft tube 11 forward to deflect it into its normal position at the side edge of the front side column 1.
[0041] Referring to the Fig. 13 to Fig. 15, the translocation mechanism 20 also includes an elastic element 22. The elastic element 22 is a torsional spring or a compression spring and is located between the connecting section 13 and the limiting section 21. The elastic element 22 imparts backward elasticity to the connecting section 13 of the retractable corrugated tube 11 to assist in pushing the retractable corrugated tube 11 backward. Alternatively, the elastic element 22 can provide forward elasticity to the connecting section 13 of the retractable corrugated tube 11 to additionally push the retractable corrugated tube 11 forward.
[0042] Referring to the Fig. 13 to Fig. 15. When the curtain 12 of the curtain mechanism 10 is extended, the drive bar 422, driven by the motor-gearbox assembly 421, exerts a reverse force on the drive arm 41. The drive arm 41 generates a reverse pulling force on the curtain 12 of the curtain mechanism 10. The forward-tilted retractable shaft tube 11 is deflected rearward from the side edge of the front side column 1. The connecting section 13 of the retractable shaft tube 11 is limited by the limiting section 21. The retractable shaft tube 11 is deflected rearward into its normal position in the vertical state and then ceases to deflect. Then, the drive bar 422, driven by the motor-gearbox assembly 421, drives the drive arm 41 to exert a downward force on the curtain 12 of the curtain mechanism 10.The curtain 12 is pulled out of the retractable corrugated tube 11 and stopped when the actuating side plate 121 of the curtain 12 moves towards the rear of the rear side window 2.
[0043] Referring to the Fig. 13 to Fig.15, the curtain 12 of the curtain mechanism 10 is rolled up, and the drive bar 422, driven by the motor-gearbox assembly 421, exerts the forward force on the drive arm 41. The drive arm 41 generates the forward tensile force on the curtain 12 of the curtain mechanism 10. Simultaneously, the curtain 12 is automatically rolled up by the retractable shaft tube 11. The drive arm 41 moves forward to the predetermined position at the front end 31 of the track 30. The push rod 25, attached to the lower end of the drive arm 41, presses on the retractable shaft tube 11, and the curtain mechanism 10 is deflected forward into the folded position. If the front side column 1 has the retraction space 1A, the curtain mechanism 10 is moved into the folded position, received into the retraction space 1A of the front side column 1, and concealed within the front side column 1.
[0044] In the aforementioned descriptions of the various embodiments, the sunshade curtain, through its overall structure, ensures that the rear of the vehicle's side wall is provided with a shading effect. Furthermore, when the sunshade curtain is folded, the curtain mechanism 10 is deflected forward to a position near the inner surface of the front side pillar 1, which is located in front of the rear side window of the vehicle's side wall. The sliding curtain mechanism 10 is located near or concealed within the front side pillar 1 to maintain the integrity and aesthetics of the vehicle interior. Additionally, when the curtain 12 is extended, the curtain mechanism 10 is moved from a forward-tilted position to a rearward, vertical position, and then the curtain 12 is pulled out.A lower edge of the extended curtain 12 lies close to a lower edge of the rear side window in order to shade the rear side window flush and thus achieve a greater shading rate for the rear side window.
[0045] A lower edge of the extended curtain lies close to a lower edge of the rear side window to shade the rear side window flush, in order to provide a greater shading rate for the rear side windows and achieve an optimal shading effect.
