Description

Technical Field

[0001] The utility model relates to a manual side window rolling curtain device for shielding sunlight at the side windows of a motor vehicle. Background Art

[0002] Currently, rolling curtain devices installed on the side windows of motor vehicle doors are generally classified into two types: manual and electric. Manual side window rolling curtain devices consist of a curtain reel assembly and a curtain connected to the reel assembly. The reel assembly is positioned transversely within the vehicle door. The curtain can be pulled out of the reel assembly and automatically retracted by the reel assembly. The curtain of existing manual side window rolling curtain devices can be extended and retracted either transversely or longitudinally.

[0003] When the curtain of the aforementioned manual side window roller blind device is configured for longitudinal expansion and contraction, to ensure the curtain is stably supported and positioned after it is extended upward, the manual side window roller blind device further includes a support rod and an operating unit. The support rod is movable up and down within the vehicle door and is connected to the middle section of the curtain's movable side strip. The operating unit is located within the vehicle door and is capable of locking and unlocking the support rod. Thus, when the curtain is pulled upward to expand, the support rod rises along with the curtain's movable side strip. After the curtain is extended, the support rod is positioned by the force of the operating unit, providing support for the curtain and maintaining its extended state. When the curtain is pulled downward to retract, the curtain reel assembly applies a retracting force to the curtain, causing it to retract.

[0004] While the aforementioned conventional manual side window roller blind device can provide a roller blind device for sunshade applications on the side windows of motor vehicles, the operating unit for locking and unlocking the support rod in this manual side window roller blind device is composed of multiple independent components, each of which must be individually installed in the vehicle door and then assembled together, making it a non-modular mechanism. Due to the limited assembly space within the vehicle door, it is not convenient to install the aforementioned manual side window roller blind device in the vehicle door. Furthermore, during the operation of unfolding and retracting the curtain, the operating unit must be separately operated to switch the locking and unlocking states of the support rod. This makes it difficult to directly switch the locking and unlocking of the support rod by pulling the curtain up or down, and the curtain cannot be pulled and stopped at will, resulting in inconvenience in use. Utility Model Content

In this way, the two-way positioner is combined with the support unit that can be raised and lowered with the edge strip and the curtain reel assembly that can automatically rewind the curtain, so that the curtain can stop as it is pulled during the process of pulling up or pulling down, and the operation is simple.

[0027] 2. The modular structure is easy to assemble: The manual side window roller blind device of the utility model can be installed in the vehicle door and connected to the supporting unit with a pre-assembled modular structure, so that it can be easily assembled when installed in the vehicle door.

[0028] The manual side window roller blind device of the present invention can further utilize the support unit including a hard shaft and a soft shaft connected to the lower end of the hard shaft, so that the support unit can shorten the length of the hard shaft and form a structure in which the lower section of the support unit can bend laterally, and is matched with a multi-section telescopic tube group that is sleeved on the outside of the support unit and can be extended and retracted in the vehicle door to provide auxiliary supporting force for the hard shaft of the support unit, thereby reducing the longitudinal stroke of the support unit in the vehicle door and effectively reducing the assembly space of the manual side window roller blind device in the vehicle door.

[0029] The manual side window roller blind device of the present invention can further utilize the section of the support unit that can be engaged by the stop component to be provided with multiple teeth and grooves to form a rack shape.

[0082] The following is a detailed description of the technical means used by the present invention to achieve the intended purpose with reference to the accompanying drawings and embodiments of the present invention.

[0083] According to the technical solution of the above utility model, the manual side window roller blind device of the utility model can at least Figure 1 、 Figure 4 and Figure 13The disclosed embodiments are implemented in a manner that allows the manual side window roller blind to be installed in a door of a motor vehicle and located at the side window of the door to provide sunlight shielding. The manual side window roller blind comprises a curtain reel assembly 10, a curtain 20, support units 30 and 40, and a bidirectional positioner 50.

[0084] like Figures 1 to 2 、 Figures 4 and 5 and Figure 13 As shown, the curtain reel assembly 10 can be installed in the vehicle door and located below the side window of the vehicle door, and includes an axle seat 11 and a reel group 12. The axle seat 11 is installed in the vehicle door and located below the side window. The axle seat 11 has an opening exposed below the side window of the vehicle door. The reel group 12 is installed in the axle seat 11 and can automatically reel up the curtain 20. The reel group is an existing product and its specific structure is not repeated here.

[0085] like Figures 1 to 2 、 Figures 4 and 5 and Figure 13 As shown, the two different sides of the curtain 20 are respectively a connecting edge and a movable edge, and the connecting edge is connected to the reel group 12 of the curtain reel assembly 10. The movable edge is located on the outer side of the shaft seat 11 and has a side strip 21. The side strip 21 has a handle 22. In this embodiment, the handle 22 is located in the middle section of the side strip 21. The user can hold the handle 22 to drive the curtain 20 to unfold upward from the curtain reel assembly 10 and pull the curtain 20 downward to the curtain reel assembly 10.

[0086] like Figures 1 to 2 、 Figures 4 and 5 and Figure 13 As shown, the support units 30, 40 are installed in the vehicle door and connected to the edge strip 21 of the curtain 20. In this embodiment, the upper ends of the support units 30, 40 are connected to the middle section of the edge strip 21, and can be pulled upward and unfolded along with the curtain 20 to extend from under the side window of the vehicle door and provide support for the curtain 20, and can be retracted into the vehicle door when the curtain 20 is folded downward.

[0087] like Figure 2 、 Figure 5 、 Figure 10 and Figure 14As shown, the two-way locator 50 can be installed in the vehicle door and connected to the support units 30, 40. The two-way locator 50 includes a stop member 54 under elastic force. The two-way locator 50 can move up and down along with the edge strip 21 of the curtain 20 in the support units 30, 40. The stop member 54 under elastic force can weaken the force on the support units 30, 40 and automatically unlock. When the support units 30, 40 stop, one side of the support units 30, 40 is limited by the abutment walls 512, 512 of the longitudinal groove 511, and the stop member 54 under elastic force can exert force on the other side of the support units 30, 40. The automatic locking means that during the bidirectional movement of the side strip 21 of the curtain 20 rising or falling, the bidirectional positioner 50 can weaken the force acting on the support units 30 and 40 that rise and fall along with the side strip 21, and unlock the support units 30 and 40; when the curtain 20 stops moving, the bidirectional positioner 50 can exert force on the support units 30 and 40 to lock them, immediately preventing the support units 30 and 40 from rising and falling, and maintaining the state in which the support units 30 and 40 stably support the positioning of the curtain 20. In this way, during the process of pulling the curtain 20 up or down, the bidirectional positioner 50 can be used in conjunction with the support units 30 and 40 to stop as the curtain 20 is pulled up or down.

[0088] like Figures 1 to 2 、 Figures 4 and 5 and Figure 13 In the illustrated embodiment, the support unit 30 comprises a rigid shaft 31 and a flexible shaft 32 connected to the bottom end of the rigid shaft 31. The rigid shaft 31 is rigid enough to support the curtain 20 and is made of, for example, aluminum alloy or stainless steel. The flexible shaft 32 is flexible and is made of, for example, a nylon cable. The lateral bending of the flexible shaft 32 shortens the lifting and lowering travel of the support unit 30. When the length of the rigid shaft 31 is shorter than the height of the vehicle window, or when the length of the flexible shaft 32 is increased, the support unit 30 further incorporates a multi-section telescopic tube assembly 33 to provide auxiliary support. This multi-section telescopic tube assembly 33 is mounted outside the rigid shaft 31 and can extend and retract as the support unit 30 is raised or lowered.

[0089] like Figures 1 to 2 and Figure 13 As shown, in this embodiment, the multi-section telescopic tube assembly 33 comprises multiple sections of serially connected tubes 331, 332, and 333, each with decreasing diameter. Specifically, when the multi-section telescopic tube assembly 33 is collapsed, the tube 331 with the smallest diameter is located at the innermost portion of the collapsed multi-section telescopic tube assembly 33 and is positioned over the outer portion of the rigid shaft 31. Tubes 332 and 333 of progressively larger diameters are positioned over the outer portion of the collapsed multi-section telescopic tube assembly 33. The multi-section telescopic tube assembly 33 is an existing product and is commonly found in conventional telescopic antennas. Therefore, the detailed structure of the multi-section telescopic tube assembly 33 will not be further described here.

[0090] like Figures 1 to 2 and Figure 13 As shown, the multi-section telescopic tube assembly 33 is fixed in the vehicle door by the tube 333 with the largest diameter, or by a fixing base 334. The fixing base 334 is installed in the vehicle door and is fixed to the tube 334 at the lowest position (largest diameter) of the multi-section telescopic tube assembly 33 when extended. The upper end of the tube 333 at the lowest position (largest diameter) is close to the lower edge of the side window, so that the multi-section telescopic tube assembly 33 can be fully retracted into the vehicle door.

[0091] like Figures 1 to 2 and Figure 13 As shown, the rigid shaft 31 and the flexible shaft 32 of the support unit 30 pass through the fixing seat 334 and the interior of the multi-section telescopic tube assembly 33. The length of the rigid shaft 31 roughly matches the length of the multi-section telescopic tube assembly 33 and can also be set according to actual product usage requirements. The lower end of the rigid shaft 31 can be engaged and disengaged with the upper end of the tube 331 at the highest position (with the smallest diameter) in the multi-section telescopic tube group 33 when extended. After the curtain 20 is pulled upward and unfolded, the lower section of the rigid shaft 31 can drive the tube 331 at the highest position (with the smallest diameter) in the multi-section telescopic tube group 33 when extended to rise, thereby pulling the multi-section telescopic tube group 33 to extend. When the curtain 20 is pulled downward to be retracted, the multi-section telescopic tube group 33 descends and shortens along with the rigid shaft 31. In addition, the auxiliary support units 30 and 40 composed of the fixed seat 334 and the multi-section telescopic tube group 33, combined with the support units 30 and 40, provide the curtain 20 with telescopic support performance.

[0092] like Figure 4 and Figure 5 In another embodiment shown, the support unit 40 uses a long hard shaft 41. Based on the rigidity of the hard shaft 41, it can directly support the curtain 20. The support unit 40 is combined with a fixing part 42 and installed in the vehicle door. The hard shaft 41 of the support unit 40 passes through the fixing part 42. When the curtain 20 is unfolded upward or folded downward, the hard shaft 41 provides support performance for the curtain 20 with the auxiliary support of the fixing part 42.

[0093] like Figures 1 to 2 and Figures 4 and 5 In the disclosed embodiment, the bidirectional positioner 50 is a modular assembly structure, so that the bidirectional positioner 50 can be installed in the vehicle door in conjunction with the support units 30 and 40. The bidirectional positioner 50 includes a housing 51, a sliding seat 52, an elastic element 53, a stopper 54, and an elastic member 55.

[0094] like Figure 7 and Figure 10As shown, the housing 51 has a longitudinal channel 511 through which the support units 30 and 40 can pass. The housing 51 has a supporting wall 512 on one lateral side of the longitudinal channel 511. The housing 51 has a receiving groove 513 on the other lateral side of the longitudinal channel 511 that is connected to the longitudinal channel 511. The receiving groove 513 has a groove side wall 514 on the lateral side away from the longitudinal channel 511. The support units 30 and 40 pass through the longitudinal channel 511 and can move (up and down) along the longitudinal channel 511. The housing 51 can also be equipped with a cover plate 510 to cover the outer sides of the longitudinal channel 511 and the receiving groove 513.

[0095] like Figure 7 and Figure 10 As shown, the sliding seat 52 is installed in the receiving groove 513 of the housing 51 and can move toward and away from the longitudinal groove 511 .

[0096] like Figure 7 and Figure 10 As shown, the elastic element 53 is arranged in the receiving groove 513 of the shell 51 to apply an elastic force to the sliding seat 52 toward the longitudinal groove 511. In this embodiment, the elastic element 53 can be a compression spring or a spring, and is installed between the groove side wall 514 of the receiving groove 513 and the sliding seat 52.

[0097] like Figure 7 and Figure 10 As shown, the stop member 54 is pivoted in the sliding seat 52 and can rotate up and down. The stop member 54 includes a base 541 and a stop portion 542 located at one end of the base 541. The base 541 is pivoted to the sliding seat 52 by a pivot column 515. The other end of the base 541 has two stop columns 543 arranged at intervals in the upper and lower directions. The stopping portion 542 extends toward the longitudinal groove 511 and can abut against the support units 30, 40, and cooperates with the abutting wall 512 of the longitudinal groove 511 to relatively clamp the support units 30, 40. When the stop component 54 pushes the support units 30, 40 laterally, the sliding seat 52 applies force to the elastic element 53, so that the elastic element 53 accumulates elastic potential energy. At the same time, the stop component 54 applies a pushing force to the support units 30, 40 under the action of the elastic force, thereby preventing the support units 30, 40 from moving; when the support units 30, 40 are operated to rise or fall, the stop component 54 is driven to rotate upward or downward due to the friction force of the support units 30, 40, thereby weakening the resistance of the stop component 54 on the support units 30, 40, so that the support units 30, 40 can be easily operated to rise or fall.

[0098] like Figure 7 and Figure 10As shown, the elastic member 55 can be a torsion spring, a spring plate, or multiple springs. The elastic member 55 is disposed between the sliding seat 52 and the stop member 54 and provides elastic force to the stop member 54. When the stop member 54 is vertically abutting the support units 30 and 40, the elastic member 55 does not exert any force on the stop member 54. When the stop member 54 rotates upward or downward, the elastic member 55 is driven by the stop member 54's support posts 543, causing it to deflect and accumulate elastic potential energy. When the external force acting on the stop member 54 disappears, the elastic member 55 pushes against the stop member 54 to automatically return to its normal position. In this embodiment, the elastic member 55 is a spring plate. One end of the elastic member 55 is fixed to the sliding seat 52, and the other end of the elastic member 55 passes between the two support posts 543 and exerts an elastic force on the stop member 54. However, this is not a limitation.

[0099] In the above, the stop member 54 can be a ratchet member with one or more ratchets or a cam. When the stop member 54 is a ratchet member, as shown in FIG. Figure 2 、 Figure 5 and Figure 7 In the illustrated embodiment, the support units 30 and 40 may further be provided with a plurality of tooth grooves 321 and 411 in the section that can be engaged by the stop member 54, thereby forming a rack-like shape. When the support unit 30 is an embodiment comprising a hard shaft 31 and a flexible shaft 32 disposed at the bottom end of the hard shaft 31, the plurality of tooth grooves 411 are disposed on the flexible shaft 32; when the support unit 40 is an embodiment comprising a single hard shaft 41, the plurality of tooth grooves 411 are disposed on the hard shaft 41. The tooth grooves 321 and 411 provide a location for the stop portion 542 of the stop member 54 to engage, thereby enhancing the stability of the stop member 54 in securing the support units 30 and 40.

[0100] like Figure 10 As shown, when the flexible shaft 32 of the support unit 30 is made of a material that can be squeezed and deformed, the flexible shaft 32 may not be provided with a tooth groove, and the stop component 54 may be selected as a cam, and the stop portion 542 of the stop component 54 is directly used to apply a pushing pressure to the flexible shaft 32 of the support unit 30, and the support unit 30 is relatively clamped by the abutting wall 512 of the longitudinal groove 511, thereby presenting a state of locking the support unit 30. At the same time, the stop component 54 applies a pushing force to the support unit 30 under the action of elastic force, which can further prevent the support unit 30 from moving.

[0101] like Figure 13 In the disclosed embodiment, when the flexible shaft 32 of the support unit 30 is made of a material that can be extruded and deformed, the bidirectional locator 50 also adopts another modular combination structure to facilitate the installation of the bidirectional locator 50 in the vehicle door in combination with the support unit 30. The bidirectional locator includes a shell 51, a stop component 54 and a torsional elastic component 56.

[0102] like Figure 13 、 Figure 14 As shown, the housing 51 has a longitudinal channel 511, and an abutting wall 512 is provided on one lateral side of the longitudinal channel 511. A recess 5121 is provided in the abutting wall 512. The abutting wall 512 has an abutting surface on the upper and lower sides of the recess 5121. The housing 51 has an accommodating groove 513 on the other lateral side of the longitudinal channel 511 that is connected to the longitudinal channel 511. The support unit 30 can pass through the longitudinal channel 511 and move along the longitudinal channel 511 (in the vertical direction). The housing 51 can also be provided with a cover plate 510, so that the cover plate 510 covers the outer sides of the longitudinal channel 511 and the accommodating groove 513.

[0103] like Figure 13 、 Figure 14 As shown, the stop member 54 is pivotally mounted in the receiving slot 513 of the housing 51 via a pivot post and is capable of rotating up and down. One end of the stop member 54 has a stop portion 542 that extends toward the longitudinal channel 511 and is capable of pushing against the support unit 30. The stop member 54 can be a cam or a ratchet member having one or more ratchet teeth. In this embodiment, the stop member 54 is a cam. When the stop member 54 is a ratchet member, the stop portion 542 forms the ratchet teeth.

[0104] like Figure 13 、 Figure 14 As shown, the torsion elastic component 56 is connected between the stop component and the housing 51 and provides a torsion elastic force to the stop component 54. The torsion elastic component 56 can be a torsion spring or other elastic component that can rotate and reset the deflected stop component 54.

[0105] like Figure 13 、 Figure 14 As shown, the aforementioned bidirectional locator 50 acts on the support unit 30. The stop component 54 utilizes the elastic force provided by the torsional elastic component 56 to cause the stop portion 542 to apply a lateral force to the support unit 30, so that the support unit 30 is positioned in the bidirectional locator 50. When the flexible shaft 32 with a bendable property in the support unit 30 is subjected to the lateral pushing force of the stop component 54, the pushed section of the flexible shaft 32 is deformed and bent to extend into the recess 5121 of the abutment wall 512. At the same time, the upper and lower sections of the flexible shaft 32 in the deformed section abut against the abutment wall 512. By the relative clamping force of the stop component 32 and the abutment wall 512 on the flexible shaft 32 of the support unit 30, the support unit 30 is prevented from moving and is positioned in the bidirectional locator 50.

[0106] like Figure 15 、 Figure 16As shown, when the support unit 30 is operated to rise or fall, the stop component 54 is deflected upward or downward by the friction of the support unit 30, thus weakening the resistance of the stop component 54 to the support unit 30, so that the support unit 30 can be easily operated to rise or fall, and on the other hand, the torsional elastic component 56 is deflected by the stop component 54 to accumulate torsional elastic potential energy, so as to provide the elastic force of the stop component 54.

[0107] As shown in Figure 3 , Figure 6 , when the manual side window roller blind device of the utility model is installed in the door of a motor vehicle and used, in the state of the curtain cloth 20 being retracted, the curtain cloth 20 is automatically retracted by the roller shaft group in the shaft seat 11, and the edge strip 21 of the curtain cloth 20 is located at the upper end opening of the shaft seat 11. At this time, one side of the support unit 30, 40 is limited by the abutting wall 512 of the longitudinal channel 511 of the bidirectional positioner 50, and the stop component 54 of the bidirectional positioner 50 is pressed transversely against the support unit 30, 40 under the action of the elastic force to generate a clamping effect, so that the support unit 30, 40 is in a locked state.

[0108] As shown in Figures 1 to 2 , Figures 4 and 5 and Figure 13 , when the user holds the pull handle 22 of the edge strip 21 of the curtain cloth 20 to pull the curtain cloth 20 upward to unfold, the support unit 30, 40 connected to the edge strip 21 rises along with the edge strip 21. At this time, the stop component 54 of the bidirectional positioner 50, which originally abuts against and locks the support unit 30, 40, is deflected upward by the friction of the support unit 30, 40, thus weakening the resistance of the stop component 54 to the support unit 30, 40, so that the support unit 30, 40 can be easily operated to rise.

[0109] As shown in Figures 1 to 2 and Figures 4 and 5 , until the user stops pulling the edge strip 21 of the curtain cloth 20 upward, and the external force of the support unit 30, 40 acting on the stop component 54 disappears, the stop component 54 is pushed to automatically turn right back to the original position by the reset elastic force provided by the elastic component 55, and under the action of the elastic force of the elastic element 53 on the sliding seat 52, the stop component 54 re-applies force to the support unit 30, 40 to automatically lock. Alternatively, as shown in Figure 13 , the stop component 54 is pushed to automatically turn right back to the original position by the torsional elastic force provided by the torsional elastic component 56, so that the stop component 54 re-applies force to the support unit 30 to automatically lock.

[0110] As shown in Figures 1 to 3 , Figures 4 to 6 and Figure 13As shown, similarly, when the curtain 20 is in the unfolded state, when the user holds the handle 22 of the edge strip 21 of the curtain 20 and pulls the curtain 20 downward to fold it, the two-way positioner 50 can also automatically unlock the support units 30 and 40, and when the user stops pulling down the edge strip 21 of the curtain 20, the two-way positioner 50 automatically restores the lock on the support units 30 and 40. In this way, the curtain 20 can be stopped as it is pulled during the process of being pulled up or down, and the operation is simple.
