[0041] Referring to Figure 1 and Figure 2 , Figure 1 shows a structural schematic diagram of a sunshade curtain winding mechanism 10 in an embodiment of the present application, Figure 2 is Figure 1 an exploded view of the sunshade curtain winding mechanism 10. The sunshade curtain winding mechanism 10 provided in an embodiment of the present application includes a support rod 100, a shaft sleeve 200, a first elastic member 300, a second elastic member 400, a sleeve 500, a first fixed seat 600 and a second fixed seat 700. The shaft sleeve 200 is fixedly sleeved on the support rod 100. The first elastic member 300 and the second elastic member 400 are respectively sleeved on the support rod 100 on both sides of the shaft sleeve 200, and one end of each of the first elastic member 300 and the second elastic member 400 close to the shaft sleeve 200 is fixedly connected with the shaft sleeve 200. The sleeve 500 is sleeved on the first elastic member 300 and the second elastic member 400. The first fixed seat 600 and the second fixed seat 700 are respectively fixedly connected with both ends of the sleeve 500, and the first fixed seat 600 is fixedly connected with one end of the first elastic member 300 away from the shaft sleeve 200, and the second fixed seat 700 is fixedly connected with one end of the second elastic member 400 away from the shaft sleeve 200.

[0042] The sunshade curtain winding mechanism 10 is assembled in the following manner: first, the shaft sleeve 200 is fixedly sleeved on the support rod 100; then, the first elastic member 300 and the second elastic member 400 are respectively sleeved on the support rod 100 at two sides of the shaft sleeve 200 and are fixedly connected with the shaft sleeve 200; finally, the first elastic member 300 and the second elastic member 400 are fixedly connected with two ends of the sleeve pipe 500 through the first fixed seat 600 and the second fixed seat 700, thereby achieving simple installation and fixation of the first elastic member 300 and the second elastic member 400. When disassembling the sunshade curtain winding mechanism 10, only the reverse order of operation is needed. The above scheme has the advantages of simple structure, reduced amount of structural members, reduced assembly difficulty, and improved disassembly and assembly convenience of the sunshade curtain winding mechanism 10.

[0043] In addition, when the sunshade curtain winding mechanism 10 is running, the outer circumferential surface of the sleeve pipe 500 is used to attach the winding sunshade curtain. When the sunshade curtain attached and wound outside the sleeve pipe 500 is unfolded and drives the sleeve pipe 500 to rotate, the sleeve pipe 500 drives the first elastic member 300 and the second elastic member 400 to generate a torsion force because the respective one ends of the first elastic member 300 and the second elastic member 400 are fixedly connected with the end portions of the sleeve pipe 500, thereby causing the sleeve pipe 500 to continuously exert a recovery force on the sunshade curtain under the torsion force of the first elastic member 300 and the second elastic member 400, so as to ensure that the sunshade curtain is in a tight and flat state.

[0044] The above scheme is adopted in the present application. The shaft sleeve 200 and the support rod 100 are nested with each other, which helps to increase the contact area and enhance the strength of the mutual fixed connection of the shaft sleeve 200 and the support rod 100. When the first elastic member 300 and the second elastic member 400 are twisted, the shaft sleeve 200 can better disperse the load caused by the twisting of the first elastic member 300 and the second elastic member 400, thereby improving the running stability of the first elastic member 300 and the second elastic member 400.

[0045] Alternatively, the fixing manner of the shaft sleeve 200 fixedly sleeved on the support rod 100 can be, but is not limited to, fixed by bolts, fixed by a clamping manner, fixed by being screwed through the setting of internal and external threads, or the like.

[0046] Alternatively, as shown in Figure 2 The sunshade curtain winding mechanism 10 can include a first limiting member 250. The shaft sleeve 200 is limited on the support rod 100 by the first limiting member 250, so as to realize the relative fixed arrangement of the shaft sleeve 200 and the support rod 100.

[0047] Preferably, as shown in Figure 2As shown, the sleeve 200 can be provided with a first socket 200a along its circumferential surface, and the support rod 100 can be provided with a second socket 100a along its circumferential surface. The first socket 200a and the second socket 100a are aligned with each other to plug in the first limit member 250, thereby realizing the quick disassembly and assembly of the sleeve 200 and the support rod 100, thereby improving the ease of disassembly and assembly of the sunshade curtain retracting mechanism 10.

[0048] Optionally, the first limiting member 250 may be, but is not limited to, implemented as a pin.

[0049] More preferably, the first socket 200a can be, but is not limited to, implemented as having at least 2, the number of the second sockets 100a is the same as the number of the first sockets 200a, and each first socket 200a and each second socket 100a are aligned with each other to plug into the first limit member 250, so as to improve the strength of the fixed connection between the sleeve 200 and the support rod 100.

[0050] For example, see Figure 2 The first sockets 200a can have two, and correspondingly, the second sockets 100a also have two. The two first sockets 200a are aligned with the two second sockets 100a. Furthermore, there are two first stoppers 250, each of which is configured to be plugged into the aligned first and second sockets 200a, 100a. It is understood that the number of first sockets 200a, second sockets 100a, and first stoppers 250 can be three, four, or five, etc.

[0051] Optionally, the ends of the first elastic member 300 and the second elastic member 400 are fixedly connected to the shaft sleeve 200 by, but not limited to, being clamped or bonded to each other.

[0052] Optionally, combined Figure 2 As shown, the sleeve 200 can be provided with a first connecting portion 210 and a second connecting portion 220 on both sides along its axial direction, one side of the sleeve 200 is fixedly connected to the first elastic member 300 through the first connecting portion 210, and the other side of the sleeve 200 is fixedly connected to the second elastic member 400 through the second connecting portion 220, thereby achieving relative fixation between the first elastic member 300 and the second elastic member 400 and the sleeve 200.

[0053] Optionally, the first connection part 210 and the second connection part 220 can be connected to the first elastic part 300 and the second elastic part 400 respectively through connecting parts, or the first connection part 210 is directly connected to the first elastic part 300, and the second connection part 220 is directly connected to the second elastic part 400.

[0054] Preferably, combined Figure 2As shown, the first connecting portion 210 can be provided with a first threaded portion, the second connecting portion 220 can be provided with a second threaded portion, the first elastic member 300 is clamped on one side of the sleeve 200 along the thread diameter of the first threaded portion, and the second elastic member 400 is clamped on the other side of the sleeve 200 along the thread diameter of the second threaded portion, so that the first elastic member 300 and the second elastic member 400 can be quickly disassembled with the sleeve 200, and the disassembly convenience of the sunshade curtain rolling mechanism 10 is improved.

[0055] Specifically, the first elastic member 300 and the second elastic member 400 are preferably implemented as spring members with a spiral shape, so that they can be respectively screwed and clamped on the sleeve 200 along the thread diameter of the first threaded portion and the thread diameter of the second threaded portion, and the first elastic member 300 and the second elastic member 400 can be quickly disassembled.

[0056] More preferably, referring to Figure 3 , the sleeve 200 is provided with a first clamping interface 230 and a second clamping interface 240 on both sides of the sleeve 200 along the axial direction. The first elastic member 300 has a first clamping end head 310 clamped on the first clamping interface 230, and the second elastic member 400 has a second clamping end head 410 clamped on the second clamping interface 240, so that the fixing effect of the first elastic member 300 and the second elastic member 400 relative to the sleeve 200 can be further improved.

[0057] In addition, when the first elastic member 300 is twisted, the first elastic member 300 and the first threaded portion are screwed with each other, and the first clamping end head 310 and the first clamping interface 230 are clamped with each other, which helps to improve the stability of the dynamic operation of the first elastic member 300. Similarly, when the second elastic member 400 is twisted, the second elastic member 400 and the second threaded portion are screwed with each other, and the second clamping end head 410 and the second clamping interface 240 are clamped with each other, which helps to improve the stability of the dynamic operation of the first elastic member 300.

[0058] Preferably, the rotation direction of the first threaded portion can be but not limited to consistent with the rotation direction of the first elastic member 300 when it is twisted and deformed. For example, the rotation direction of the first threaded portion is clockwise, and similarly, the first elastic member 300 is screwed into the first threaded portion along the thread diameter in the clockwise direction. When the first elastic member 300 is twisted, since the rotation direction of the first threaded portion is consistent with the rotation direction of the first elastic member 300 when it is twisted and deformed, the first elastic member 300 can be twisted in the direction of being screwed into the first threaded portion, so that the first elastic member 300 can be prevented from being twisted in the opposite direction and separated from the sleeve 200, and the working reliability of the first elastic member 300 is improved.

[0059] Preferably, the direction of rotation of the second threaded portion can be, but is not limited to, implemented to be consistent with the direction of rotation of the second elastic member 400 being twisted and deformed. For example, the direction of rotation of the second threaded portion is clockwise, and likewise, the second elastic member 400 is screwed into the threaded diameter of the second threaded portion in a clockwise direction, and when the second elastic member 400 is moved to be twisted, since the direction of rotation of the second threaded portion is consistent with the direction of rotation of the second elastic member 400 being twisted and deformed, the second elastic member 400 can be twisted in the direction of being screwed into the second threaded portion, and thus the first elastic member 300 can be prevented from being twisted in the opposite direction and disengaged from the sleeve 200, thereby improving the working reliability of the first elastic member 300.

[0060] Optionally, referring to Figure 4 , the first fixed seat 600 can be provided with a third connecting portion 610 along the axial direction thereof, and the first fixed seat 600 is fixedly connected to the end of the first elastic member 300 away from the sleeve 200 through the third connecting portion 610. The second fixed seat 700 can be provided with a fourth connecting portion (not shown) along the axial direction thereof, and the second fixed seat 700 is fixedly connected to the end of the second elastic member 400 away from the sleeve 200 through the fourth connecting portion, thereby realizing the relative fixation of the first fixed seat 600 and the first elastic member 300, and the relative fixation of the second fixed seat 700 and the second elastic member 400.

[0061] Optionally, the third connecting portion 610 and the fourth connecting portion can be connected to the first fixed seat 600 and the second fixed seat 700, respectively, through connecting members, or the third connecting portion 610 is directly connected to the first fixed seat 600, and the fourth connecting portion is directly connected to the second fixed seat 700.

[0062] Preferably, referring to Figure 4 , the third connecting portion 610 can be provided with a third threaded portion, and the end of the first elastic member 300 away from the sleeve 200 is clamped to the first fixed seat 600 along the threaded diameter of the third threaded portion, thereby realizing the fixed connection of the first elastic member 300 and the first fixed seat 600, and realizing the quick disassembly and assembly between the first elastic member 300 and the first fixed seat 600, thereby improving the disassembly and assembly convenience of the sunshade curtain rolling mechanism 10.

[0063] Preferably, the fourth connecting portion can be provided with a fourth threaded portion, and the end of the second elastic member 400 away from the sleeve 200 is clamped to the second fixed seat 700 along the threaded diameter of the fourth threaded portion, thereby realizing the fixed connection of the second elastic member 400 and the second fixed seat 700, and realizing the quick disassembly and assembly between the second elastic member 400 and the second fixed seat 700, thereby improving the disassembly and assembly convenience of the sunshade curtain rolling mechanism 10.

[0064] Preferably, in combination with Figure 2 and Figure 4As shown, the first fixed seat 600 can be provided with a third clamping interface 620, and the first elastic member 300 has a third clamping end head 320 at the end away from the shaft sleeve 200, which is clamped in the third clamping interface 620; the second fixed seat 700 can be provided with a fourth clamping interface (not shown), and the second elastic member 400 has a fourth clamping end head 420 at the end away from the shaft sleeve 200, which is clamped in the fourth clamping interface, so as to improve the clamping and fixing effect between the first elastic member 300 and the first fixed seat 600, and between the second elastic member 400 and the second fixed seat 700.

[0065] It should be noted that, Figure 4 For Figure 2 In the enlarged view of one side of the sleeve 500 relative to the first fixed seat 600, the fourth threaded part and the fourth clamping interface on the second fixed seat 700 are arranged in the same way as the third threaded part and the third clamping interface 620 on the first fixed seat 600, so the related enlarged view of the second fixed seat 700 is not shown in this application.

[0066] Optionally, in combination with Figure 4 As shown, the first fixed seat 600 and the second fixed seat 700 can but not limited to be implemented to be both provided with a fixed part 800, which is inserted into the sleeve 500 and abuts against the end face of the sleeve 500, so as to realize the quick and limiting assembly of the first fixed seat 600 and the second fixed seat 700 with the sleeve 500 respectively.

[0067] Optionally, the sunshade curtain winding mechanism 10 further comprises a second limiting member 510, and the fixed part 800 is limited in the sleeve 500 by the second limiting member 510, so as to realize the relative fixation between the fixed part 800 and the sleeve 500.

[0068] Preferably, the fixed part 800 is provided with a third insertion hole 800a along the circumferential surface thereof, and the end of the sleeve 500 is provided with a fourth insertion hole 500a along the circumferential surface thereof, the third insertion hole 800a and the fourth insertion hole 500a are opposite to each other to insert the second limiting member 510, so as to realize the stable connection of the first fixed seat 600 and the second fixed seat 700 with the sleeve 500 respectively.

[0069] Specifically, when the sleeve 500 rotates around its own axis, the sleeve 500 can drive the first fixed seat 600 and the second fixed seat 700 to rotate together through the clamping action of the second limiting member 510, and then twist the first elastic member 300 and the second elastic member 400. In this way, the second limiting member 510 also plays a limiting role of driving the first fixed seat 600 and the second fixed seat 700 to rotate with the sleeve 500.

[0073] The application also provides a sunshade curtain assembly comprising the sunshade curtain winding mechanism 10 described above.

[0074] The application also provides a glass assembly comprising the sunshade curtain assembly described above.

[0075] The sunshade curtain winding mechanism 10 of the sunshade curtain assembly and the glass assembly described above has a simple structure, effectively reduces the amount of structural parts, and reduces the assembly difficulty, thereby improving the disassembly and assembly convenience of the sunshade curtain assembly. In addition, when the sunshade curtain winding mechanism 10 of the sunshade curtain assembly and the glass assembly described above is running, the shaft sleeve 200 and the support rod 100 are nested with each other, which helps to increase the contact area and enhance the strength of the mutual fixed connection between the shaft sleeve 200 and the support rod 100, so that when the first elastic member 300 and the second elastic member 400 are twisted, the shaft sleeve 200 can better disperse the load caused by the twisting of the first elastic member 300 and the second elastic member 400, thereby improving the running stability of the first elastic member 300 and the second elastic member 400.

[0076] The following is a related description of the verification process of the winding resistance of the sunshade curtain assembly and the glass assembly adopting the sunshade curtain winding mechanism 10 described above.

[0077] Based on the structure of a typical sunshade curtain assembly and glass assembly, and under normal temperature conditions, when the curtain fabric stroke of the sunshade curtain assembly reaches 1200mm, the curtain fabric resistance is 30N, and the required torque of the spring is 756N*mm; when the curtain fabric stroke reaches 1600mm, the curtain fabric resistance is 40N, and the required torque of the spring is 882N*mm; when the curtain fabric stroke reaches 1800mm, the curtain fabric resistance is 45N, and the required torque of the spring is 1071N*mm.

[0078] The running performance of the sunshade curtain assembly using the sunshade curtain winding mechanism 10 is the maximum output torque 1081N*mm calculated by structure theory, thus the spring torque demand of the 1800mm long stroke sunshade curtain can be met, the sunshade curtain runs smoothly without wrinkles, and has high working reliability and adaptability.
