Description

Technical Field

[0001] This utility model relates to a sun visor with a makeup mirror in a motor vehicle, and more particularly to a roller blind-type makeup mirror opening and closing device. Background Technology

[0002] In addition to providing sun protection for the driver or front-seat passenger, the sun visors currently installed in motor vehicles generally also have an openable and closable vanity mirror, providing a mirror for users to use when grooming in the vehicle.

[0003] Previously, the makeup mirror in the sun visor was opened and closed by a sliding cover. Due to the limited area of ​​the sun visor, enough space had to be provided inside the visor to accommodate the sliding cover, resulting in a small mirror area that could be installed inside the sun visor, causing inconvenience for users when doing their makeup.

[0004] The existing technology reveals a roller blind-type makeup mirror opening and closing device that can solve the problem that the structure of the sliding makeup mirror opening and closing device inside the sun visor would limit the mirror surface and result in a small area. This roller blind-type makeup mirror opening and closing device uses a curtain roll-up shaft assembly and a curtain that can be automatically rolled up by the curtain roll-up shaft assembly, which is installed in the assembly frame of the makeup mirror in the sun visor. The curtain roll-up shaft assembly is located in the first side frame of the assembly frame. The makeup mirror is opened and closed by the curtain that can be unfolded and rolled up. The structure that reduces space by the soft curtain being rolled up on the roll-up shaft assembly allows the makeup mirror inside the sun visor to have a moderately larger mirror surface area.

[0005] While the aforementioned roller blind-style makeup mirror opening and closing device helps increase the mirror's surface area, the unfolded curtain is subject to the winding force of the curtain retraction shaft assembly. To prevent the curtain from automatically retracting and failing to close, roller blind-style makeup mirror opening and closing devices typically incorporate multiple sets of magnetic components between the curtain edge strip and the second side frame of the makeup mirror's mounting frame. The relative magnetic attraction of these components magnetically fixes the curtain edge strip to the side frame of the mounting frame, keeping the curtain unfolded to cover the makeup mirror. When using the makeup mirror, the user applies force by pulling the handle on the curtain edge strip, disengaging the magnetic components between the curtain edge strip and the side frame of the mounting frame. The curtain then automatically retracts via the curtain retraction shaft assembly, revealing the mirror surface outside the mounting frame of the sun visor.

[0006] In the aforementioned roller blind-type cosmetic mirror opening and closing device, although the curtain edge strip is positioned on the side frame of the cosmetic mirror's mounting frame by multiple sets of magnetic components to maintain the curtain's open state, the gap between the curtain edge strip and the second side frame of the mounting frame is too large when the curtain edge strip is magnetically attracted to it, making it difficult to maintain its original appearance. Moreover, considering the force applied to open and close the curtain, the magnetic attraction force of the magnetic components is relatively small, and multiple sets of magnetic components are spaced apart, resulting in more labor-intensive assembly and higher assembly costs. Furthermore, when a motor vehicle is in motion, the gap between the curtain edge strip and the second side frame of the mounting frame causes the curtain edge strip to easily shake and generate noise.

[0007] Furthermore, a torsion spring is installed in the inner tube connecting the curtain in the curtain retraction shaft assembly, and an inner tube connecting component is connected to each end of the inner tube. The inner tube connecting components are assembled in the mounting frame of the sun visor, or a damper is further installed between one of the inner tube connecting components and the mounting frame, so that the curtain retraction shaft assembly can automatically retract the curtain. In the aforementioned curtain retraction shaft assembly or the structure with damper, the total cost is relatively high due to the large number of components and the labor-intensive assembly, and further improvements are needed. Utility Model Content

[0008] The technical problem to be solved by this utility model is that the assembly cost of the side frame of the curtain edge strip and the sun visor assembly frame of the existing roller blind-type cosmetic mirror opening and closing device is relatively high due to the use of multiple sets of magnetic components to magnetically position the curtain edge strip, and the magnetically attracted curtain edge strip is prone to shaking and generating noise when the motor vehicle is in motion.

[0009] The technical solution proposed by this utility model is: to provide a roller blind-type cosmetic mirror opening and closing device for a sun visor, which is installed in a sun visor. A cosmetic mirror is installed in an assembly frame of the sun visor. The roller blind-type cosmetic mirror opening and closing device includes a curtain roll-up shaft assembly disposed in the assembly frame and a curtain that can be automatically rolled up by the curtain roll-up shaft assembly. A curtain edge strip located on the side of the curtain can be operated to move between a first side frame portion and a second side frame portion on the other side of the assembly frame to open and close the cosmetic mirror, wherein:

[0010] The roller blind-type makeup mirror opening and closing device includes a side strip fastening and positioning structure. The side strip fastening and positioning structure includes an elastic buckle and a hook that can be operated to be relatively fastened and separated. The elastic buckle and the hook are respectively disposed at the relative positions of the curtain side strip and the second side frame of the assembly frame. The curtain side strip can be positioned on the second side frame of the assembly frame by the relative fastening of the elastic buckle and the hook.

[0011] This utility model can achieve the following beneficial effects:

[0012] 1. Low assembly cost: In the opening and closing device of the roller blind-type makeup mirror of the sunshade of this utility model, the side strip fastening positioning structure includes elastic buckles and hooks that can be operated to be fastened and separated. The elastic buckles and hooks are respectively arranged in the relative positions of the side strip of the curtain and the second side frame of the assembly frame, so that the assembly cost of the side strip fastening positioning structure can be effectively reduced.

[0013] 2. Improved stability after positioning: As mentioned above, in the roller blind-type cosmetic mirror opening and closing device of the sunshade of this utility model, its edge strip fastening positioning structure utilizes elastic buckles and hooks respectively disposed at the relative positions of the edge strip of the curtain and the second side frame of the assembly frame. The elastic buckles and hooks can be operated to securely fasten the structure, so that when the edge strip of the curtain is positioned at the second side frame of the assembly frame through the edge strip fastening positioning structure, the edge strip of the curtain can move closer to the second side frame of the assembly frame to reduce the gap between the two. At the same time, the edge strip of the curtain is securely combined and positioned by the relative fastening of the elastic buckles and hooks.

[0014] 3. Maintaining the original appearance shape: As mentioned above, when the unfolded curtain closes the makeup mirror, the curtain edge strip is stably positioned on the second side frame of the assembly frame through the relative engagement of elastic buckles and hooks. At the same time, the elastic buckles and hooks can be sized according to the needs of the product, so that the curtain edge strip can be closer to the second side frame of the assembly frame, reducing the gap between the components and maintaining the original appearance shape of the roller blind makeup mirror opening and closing device and the assembly frame.

[0015] In the roller blind-type cosmetic mirror opening and closing device described above, the elastic buckle includes a first hook and a second hook arranged opposite to each other, and the first hook and the second hook have relative expansion and closing deformation elasticity. The hook includes a snap-fit ​​portion, and the snap-fit ​​portion can be snapped together by the first hook and the second hook, thereby simplifying the edge strip snap-fit ​​positioning structure and making it easier for the elastic buckle and hook of the edge strip snap-fit ​​positioning structure to be arranged on the second side frame of the curtain edge strip and the mounting frame.

[0016] In the sun visor's roller blind-style makeup mirror opening and closing device described above, the end of the latching part forms a pointed shape. This pointed shape includes a pointed segment at the outer end and a latching segment at the inner end. The angle between the two opposing front inclined surfaces of the pointed segment is an acute angle. The two opposing rear inclined surfaces of the latching segment and the front inclined surface are opposite to each other, and the angle between the two rear inclined surfaces is an acute angle or a right angle. The end shapes of both the first and second hooks match the shape of the pointed shape at the end of the latching part. By utilizing the pointed structure at the end of the latching part of the hook, combined with the latching structure of the opposing first and second hooks in the elastic latch, it achieves easy latching and sufficient stability.

[0017] In the sun visor's roller blind-type cosmetic mirror opening and closing device described above, both the elastic buckle and the hook are pre-formed components. The elastic buckle further includes a buckle base, and the first hook and the second hook are formed on one side of the buckle base and arranged opposite to each other. The elastic buckle is fixed to the side of the curtain edge strip through the buckle base. The hook further includes a snap-fit ​​base, which is formed on the side of the snap-fit ​​base and extends laterally. The hook is fixed to the second side frame of the mounting frame through the snap-fit ​​base. This allows the pre-formed elastic buckle and hook to be easily fixed to the side of the curtain edge strip and the second side frame of the mounting frame using their respective buckle bases and snap-fit ​​bases.

[0018] In the aforementioned roller blind-style vanity mirror opening and closing device for a sun visor, the curtain edge strip includes a lower edge strip base and a upper edge strip cover. The lower edge strip base and the upper edge strip cover clamp and connect the side of the curtain fabric. The elastic buckle is integrally formed on the lower edge strip base or the upper edge strip cover; alternatively, the first hook is formed on the side of the upper edge strip cover, and the second hook is formed on the lower edge strip base. This facilitates the integral forming of the elastic buckle and the curtain edge strip, increasing manufacturing simplicity.

[0019] In the roller blind-style makeup mirror opening and closing device of the sun visor described above, the lengths of both the first and second hooks of the elastic buckle are matched with the length of the curtain edge strip, and the length of the hook is matched with the length of the elastic buckle; wherein, the second hook is provided with multiple slits at intervals along the length direction of the elastic buckle, so that the second hook is divided into multiple hook sections; the hook is provided with multiple slots at intervals along the length direction of the hook, so that the engaging part is divided into multiple engaging sections, and the length and position of each engaging section correspond to the hook section at its corresponding position.

[0020] In the sunshade-type makeup mirror opening and closing device described above, the length of the first hook of the elastic buckle matches the length of the curtain edge strip, the length of the second hook is shorter than the length of the first hook, and the second hook is located in the middle of the elastic buckle. The length of the hook matches the length of the second hook and corresponds to the middle of the elastic buckle.

[0021] In the sunshade-type makeup mirror opening and closing device described above, the length of the first hook of the elastic buckle matches the length of the curtain edge strip, the second hook has two hook blocks spaced apart at both ends corresponding to the length direction of the elastic buckle, the length of the two hook blocks is less than the length of the first hook, the hook engagement portion has two engagement blocks spaced apart along the length direction of the hook, the length and arrangement position of the two engagement blocks match the length and arrangement position of the two hook blocks respectively.

[0022] All the aforementioned variations of the elastic buckle and hook can utilize the matching length of the first hook on the outside of the elastic buckle with the length of the curtain edge strip, so that the first hook and the curtain edge strip can maintain a consistent appearance. Moreover, after the curtain edge strip is snapped together with the hook on the second side frame of the assembly frame via the elastic buckle, both the second hook and the hook can be covered by the first hook on the outside, so that the first hook of the elastic buckle can be close to and flush with the second side frame of the assembly frame, thus maintaining its original appearance shape. On the other hand, by shortening the length of the second hook of the elastic buckle, the internal stress between the materials restraining each other when the second hook is bent is reduced, giving it elasticity that is easy to bend and deform and increasing the amount of bending deformation, making it easy for the hook to be clamped and fastened in the elastic buckle.

[0023] In the sunshade-type makeup mirror opening and closing device described above, the makeup mirror opening and closing device further includes a one-way damping component. The one-way damping component is disposed at the end of the inner shaft tube of the curtain roll-up shaft assembly and connected to the first side frame of the mounting frame, and can provide damping force to the curtain roll-up shaft assembly when rolling up the curtain. The one-way damping component includes a damper and a one-way device. The one-way device includes a one-way device body and a connecting shaft connected to one end of the one-way device body. One end of the one-way device body is connected to the damper, and the other end of the one-way device body forms a ring gear. One end of the connecting shaft is pivotally provided with a plurality of planetary gears, and the plurality of planetary gears mesh with the ring gear respectively. The other end of the connecting shaft forms an inner tube assembly end with a smaller outer diameter. The inner tube assembly end can be directly assembled into the end of the inner shaft tube of the curtain roll-up shaft assembly. The connecting shaft and the inner shaft tube are linked. By utilizing a one-way damping component positioned between the inner tube of the fabric retraction shaft assembly and the first side frame of the mounting frame, the fabric can be easily pulled and unfolded from the fabric retraction shaft assembly, and the fabric can be slowly retracted. Simultaneously, this streamlined, integrated construction reduces the overall number of parts, and the integrally formed inner tube connection end of the connecting shaft facilitates easy assembly of the inner tube of the fabric retraction shaft assembly, enhancing ease of assembly.

[0037] The following description, in conjunction with the accompanying drawings and embodiments of the present invention, further illustrates the technical means adopted by the present invention to achieve its intended purpose.

[0038] like Figure 1 and Figure 2 As shown, it discloses an embodiment of the roller blind-type makeup mirror opening and closing device 2 of the sun visor 1 of the present invention. The roller blind-type makeup mirror opening and closing device 2 is installed in a sun visor 1 in a motor vehicle. The back of the sun visor 1 has a mounting frame 10 and a makeup mirror 11 disposed in the mounting frame 10. The roller blind-type makeup mirror opening and closing device 2 is installed in the mounting frame 10 of the sun visor 1 and can open and close the mirror surface of the makeup mirror 11.

[0039] like Figure 1 and Figure 2 As shown, for the convenience of describing the embodiments of this utility model, the assembly frame 10 is first defined as a first side frame 101 and a second side frame 102 on the left and right sides of the makeup mirror 11, respectively. The overall structure of the makeup mirror opening and closing device 2 mainly includes a curtain roll-up shaft group 20, a curtain 21, a curtain edge strip 22, and an edge strip fastening and positioning structure 30.

[0040] like Figure 1 and Figure 2 As shown, the curtain roll retractor assembly 20 is mounted on the first side frame portion 101 of the mounting frame 10 of the sun visor 1. The curtain roll retractor assembly 20 can be an existing product. Basically, the curtain roll retractor assembly 20 includes an inner shaft tube 201 and a torsional elastic force supply component 202 assembled inside the inner shaft tube 201. The inner shaft tube 201 is pivotally mounted on the first side frame portion 101 of the mounting frame 10. The torsional elastic force supply component 202 connects the inner shaft tube 201 and the mounting frame 10 and can provide torsional elastic force to the inner shaft tube 201.

[0041] like Figures 1 to 4 As shown, one side of the curtain 21 is connected to the curtain roll-up shaft assembly 20. In this embodiment, the side of the curtain 21 is connected to the inner shaft tube 201, and the curtain edge strip 22 is installed on the other side of the curtain 21. The curtain 21 can be automatically rolled up by the curtain roll-up shaft assembly 20. The curtain edge strip 22 can be operated to move from the first side frame portion 101 of the assembly frame 10 to the second side frame portion 102, so that the curtain 21 is unfolded and located outside the makeup mirror 11 to cover the mirror surface. The curtain edge strip 22 can also be operated to return from the second side frame portion 102 of the assembly frame 10 to the first side frame portion 101, so that the curtain 21 is gathered in the curtain roll-up shaft assembly 20, so that the mirror surface of the makeup mirror 11 is exposed.

[0042] like Figures 1 to 3 As shown, in this embodiment, a handle 220 is provided on the curtain edge strip 22 to facilitate the user to operate the curtain edge strip 22 to move.

[0043] like Figure 3 , Figure 5 and Figure 6 As shown, the edge strip fastening and positioning structure 30 includes an elastic buckle 31 and a hook 32. The elastic buckle 31 and the hook are respectively disposed at the relative positions of the curtain edge strip 22 and the second side frame portion 102 of the assembly frame 10. That is, the elastic buckle 31 is provided on either the curtain edge strip 22 or the second side frame portion 102 of the assembly frame 10, and the hook 32 is provided on the remaining one of the curtain edge strip 22 and the second side frame portion 102 of the assembly frame 10. The elastic buckle 31 and the hook 32 can be operated to be fastened and separated relative to each other. The curtain edge strip 22 is fastened to the second side frame 102 of the mounting frame 10 of the sunshade 1 by the elastic buckle 31 and the hook 32, so that the curtain edge strip 22 installed on one side of the curtain 21 is fixed to the second side frame 102 of the mounting frame 10 of the sunshade 1, and the curtain 21 remains in the unfolded state. When the elastic buckle 31 and the hook 32 are operated to separate, the curtain edge strip 22 can be operated to move towards the first side frame 101 of the mounting frame 10, and the curtain 21 is rolled up into the curtain roll-up shaft assembly 20.

[0044] like Figure 3 , Figure 5 and Figure 6 As shown, in this embodiment, the elastic buckle 31 of the edge strip fastening positioning structure 30 is provided on the curtain edge strip 22, and the hook 32 is provided at the second side frame portion 102 of the assembly frame 10 of the sunshade 1; in addition, the elastic buckle 31 can also be changed to be provided at the second side frame portion 102 of the assembly frame 10 of the sunshade 1, and the hook 32 is provided on the curtain edge strip 22. The above implementation forms with changes in position can achieve the same technical effect.

[0045] like Figure 5 and Figure 6 As shown, the elastic buckle 31 includes a first hook 311 and a second hook 312 arranged opposite to each other, and the first hook 311 and the second hook 312 have the deformation elasticity of relative expansion and closing. The hook 32 includes a snap-fit ​​portion 321, so that the snap-fit ​​portion 321 of the hook 32 can be snapped together by the first hook 311 and the second hook 312.

[0046] like Figure 5 and Figure 6As shown above, the shape of the latching portion 321 corresponds to and matches the first hook 311 and the second hook 312, so that the latching portion 321 can be clamped and fastened between the first hook 311 and the second hook 312. The end of the latching portion 321 forms a pointed body 321A, which includes a pointed segment 321B at the outer end and a latching segment 321C at the inner end. The pointed segment 321B has two front inclined surfaces with opposite directions, and the included angle between the two front inclined surfaces is an acute angle, preferably 30 degrees. The latching segment 321C has two rear inclined surfaces with opposite directions, the rear inclined surfaces following the front inclined surfaces and being opposite to each other, and the included angle between the two rear inclined surfaces is an acute angle or a right angle, preferably 45 degrees. The shapes of the ends of the first hook 311 and the second hook 312 match the pointed part 321A at the end of the latching part 321, so that the first hook 311 and the second hook 312 can clamp and fasten the latching part 321 relative to each other.

[0047] like Figure 5 and Figure 6 As shown above, the ends of the first hook 311 and the second hook 312 are further formed with outwardly inclined and mutually opposite inclined surfaces 311A ​​and 312A, which are used to match the pointed body 321A at the end of the locking part 321. This helps to guide the locking part 321 to be inserted between the first hook 311 and the second hook 312, so that the first hook 311 and the second hook 312 are pushed by the locking part 321 and the first hook 311 and the second hook 312 can easily deform and expand relative to each other and then close together to lock the locking part 321 through the mutual pushing between the inclined surfaces.

[0048] like Figure 5 and Figure 6 In the illustrated embodiment, the elastic buckle 31 and the hook 32 can be pre-formed components, which are then fixed to the curtain edge strip 22 and the second side frame portion 102 of the assembly frame 10, respectively. The elastic buckle 31 further includes a buckle base 310, with the first hook 311 and the second hook 312 formed on one side of the buckle base 310 and arranged opposite to each other. The elastic buckle 31 is fixed to the side of the curtain edge strip 22 via the buckle base 310. The hook 32 further includes a snap-fit ​​base 320, with the snap-fit ​​portion 321 formed on the side of the snap-fit ​​base 320 and extending laterally. The hook 32 is fixed to the second side frame portion 102 of the assembly frame 10 via the snap-fit ​​base 320.

[0049] Furthermore, the elastic buckle 31 can also be directly formed on the side of the fabric edge strip 22, and the hook 32 can be directly formed in the second side frame portion 102 of the assembly frame 10, achieving the same technical effect. For example, Figure 5 and Figure 6In the disclosed embodiment, the curtain edge strip 22 includes an edge strip lower seat 221 and an edge strip upper cover 222. The edge strip lower seat 221 and the edge strip upper cover 222 clamp and connect the side of the curtain 21, so that the curtain edge strip 22 is connected to the side of the curtain 21.

[0050] When the elastic buckle 31 is directly formed on the edge strip 22 of the curtain fabric, such as Figure 5 and Figure 6 As shown, the elastic buckle 31 can be integrally formed on the side of the upper cover 222 of the side strip, or the elastic buckle 31 can also be integrally formed on the side of the lower seat 221 of the side strip; or, as... Figure 7 As shown, the first hook 311 of the elastic buckle 31 is formed on the side of the upper cover 222 of the side strip, and the second hook 312 is formed on the side of the lower seat 221 of the side strip. After the lower seat 221 of the side strip and the upper cover 222 of the side strip clamp and assemble the side of the curtain fabric 21, the first hook 311 and the second hook 312 are opposite each other and form the elastic buckle 31. In this way, the elastic buckle 31 can be manufactured at the same time as the curtain fabric side strip 22 without increasing the mold cost, and the original appearance shape can be maintained.

[0051] The edge strip fastening positioning structure 30 can be further modified according to the actual usage requirements of the product, for example, by varying its length. This improves the ease and effortlessness of engaging and disengaging the elastic buckle 31 and hook 32 without affecting the stability of the connection after fastening. The length of the elastic buckle 31 can be equal to or less than the length of the curtain edge strip 22, and the hook 32 and the elastic buckle 31 can be of equal or unequal length. The following embodiments further illustrate this, wherein the second hook 312 of the elastic buckle 31 is positioned near the makeup mirror 11, and the first hook 311 is positioned away from the makeup mirror 11.

[0052] The lengths of both the first hook 311 and the second hook 312 of the elastic buckle 31 match the length of the curtain edge strip 22, and the length of the hook 32 matches the length of the elastic buckle 31. For example... Figure 8In the illustrated embodiment, the second hook 312 of the elastic buckle 31 may be further provided with a plurality of slits 313 spaced apart along the length direction of the elastic buckle 31, dividing the second hook 312 into a plurality of hook segments 3120. This reduces the internal stress between the materials when the second hook 312 bends, making each hook segment 3120 of the second hook 312 have elasticity that is easy to bend and deform and increasing the amount of bending deformation. In this way, the hook 32 can be easily clamped and fastened in the elastic buckle 31. In addition, the hook 32 may also be provided with a plurality of slits spaced apart along the length direction of the hook 32, dividing the engaging portion 321 into a plurality of engaging segments. The length and position of each engaging segment correspond to the hook segment 3120 at its corresponding position.

[0053] like Figure 9 In the embodiment shown, the length of the first hook 311 of the elastic buckle 31 matches the length of the curtain edge strip 22, the length of the second hook 312 is shorter than the length of the first hook 311, and the second hook 312 is disposed in the middle of the first hook 311 of the elastic buckle 31. The length of the hook 32 matches the length of the second hook 312 and corresponds to the middle of the elastic buckle 31.

[0054] like Figure 10 In the embodiment shown, the length of the first hook 311 of the elastic buckle 31 matches the length of the curtain edge strip 22. The second hook 312 has two hook blocks 3121, the length of which is less than the length of the first hook 311, and they are spaced apart at both ends corresponding to the length direction of the first hook 311 of the elastic buckle 31. The engaging portion 321 of the hook 32 has two engaging blocks 3211 spaced apart along the length direction of the hook 32. The length and position of the two engaging blocks 3211 match the length and position of the two hook blocks 3121, respectively.

[0055] like Figure 11 In the embodiment shown, the length of the first hook 311 of the elastic buckle 31 matches the length of the curtain edge strip 22. The second hook 312 has three hook blocks 3121, the length of each of the three hook blocks 3121 is less than the length of the first hook 311, and they are spaced apart at both ends and the middle of the first hook 311 in the length direction of the elastic buckle 31. The hook 32 is divided into three snap-fit ​​blocks 3211 spaced apart along the length direction of the hook 32. The length and position of the three snap-fit ​​blocks 3211 match the length and position of the three hook blocks 3121.

[0056] In the aforementioned embodiments, the length of the first hook 311 of the elastic buckle 31, which is located on the outside, matches the length of the curtain edge strip 22, so that it can maintain a consistent appearance with the curtain edge strip 22. When the curtain edge strip 22 is snapped together with the snap-fit ​​portion 321 of the second side frame portion 102 of the assembly frame 10 via the elastic buckle 31, both the second hook 312 and the snap-fit ​​portion 321 can be covered by the first hook 311 located on the outside. The first hook 311 of the elastic buckle 31 can be adjacent to and flush with the second side frame portion 102 of the assembly frame 10, thus maintaining its original appearance shape.

[0057] like Figure 2 , Figure 12 and Figure 13 As shown, in this embodiment, the makeup mirror opening and closing device 2 further includes a one-way damping component 40.
