[0039] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are only illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0040] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0041] The intelligent curtain control system usually includes a curtain booster 103. The control system controls the curtain booster 103 to slide on the track of the curtain system, thereby driving the curtain to move back and forth to achieve the opening and closing of the curtain. The present invention mainly describes in detail the technical means of how to install the curtain booster 103 into the curtain track 101, as follows:

[0042] like Figure 1 As shown, the curtain system 100 includes a track 101 , a curtain 102 and a curtain booster 103 . The curtain booster 103 moves in the track 101 to realize the opening and closing of the curtain 102 .

[0043] The curtain booster 103 comprises a housing 10 , a running wheel 20 , a motor 30 and a steering system of a suspension assembly. The suspension assembly 40 is connected to the track 101 , and the running wheel 20 is driven by the motor 30 .

[0044] The running wheel 20 is driven by the motor 30 to rotate, so that the running wheel 20 slides left and right along the track 101, thereby pushing the curtain to open and close.

[0045] The curtain booster 103 is mainly suspended on the track 101 through the suspension assembly 40. During actual installation, based on considerations of aesthetics and optimized structure, it is preferred that the running wheels 20 and the suspension assembly 40 are mostly covered in the housing 10.

[0046] like Figure 2 As shown, the steering system of the suspension assembly includes a suspension assembly 40 and a corresponding positioning column 50. The suspension assembly 40 includes two suspension components T. The suspension component T includes a suspension wheel group 001 extending out of the shell 10 and located in the track 101 and a column 41 extending into the shell 10. Two rollers 42 for loading the curtain track 101 are fixed to the upper end of the column 41, and the above two rollers 42 form a suspension wheel group 001.

[0047] Specifically, two suspension components T are installed on both sides of the position where the running wheel 20 is located; and the rollers 42 are installed on both sides of the end of the column 41. After installation, the rollers 42 are attached to the inner wall of the track 101 for suspension.

[0048] like Figure 4 and Fig. 20 As shown, and it is important to explain here that the outer wall of the column 41 on the suspension assembly 40 is provided with an axially extending arc groove h, and the positioning column 50 is embedded in the arc groove h. The axial movement of the column 41 causes the positioning column 50 to move along the arc groove h to realize the rotation of the column 41. That is, the positioning column 50 cooperates with the arc groove h on the column 41 to drive the column 41 to rotate while moving up and down.

[0049] like Figures 5 to 10 As shown, the column 41 that can rotate left and right can make the suspension wheel group 001 transform between the first state and the second state. The suspension wheel group 001 in the second state is parallel to the distribution direction of the track 101. In this state, the suspension wheel group 001 can be quickly inserted into the track groove of the track 101; then the column 41 rotates in the opposite direction, and the suspension wheel group 001 rotates to the first state to be perpendicular to the distribution direction of the track 101. In this first state, both ends of the suspension wheel group 001 are hung on the inner side of the track 101 by rollers 42 and are not easy to derail, thereby playing the role of suspension and auxiliary sliding.

[0050] Preferably, if Figures 7 to 10 As shown, the rotation angle of the suspension assembly 40 in this embodiment is 90 degrees. In the normal state, that is, the first state, the suspension wheel set 001 is perpendicular to the distribution direction of the track 101; after the suspension assembly 40 rotates 90 degrees, the suspension wheel set 001 is parallel to the distribution direction of the track 101, that is, the second state.

[0051] Regarding the cooperation between the positioning column 50 and the column 41, specifically: one end of the positioning column 50 is installed on the shell, and the other end is inserted into the arc groove h. When the column 41 moves upward, due to the cooperation and limitation between the positioning column 50 and the arc groove h, the column 41 can rotate forward, and the suspension wheel group 001 rotates to the second state; when the column 41 moves downward, the column 41 rotates reversely, and the suspension wheel group 001 returns to the first state.

[0052] The number of rollers 42 is preferably two, symmetrically mounted on both sides of the end of the column 41. After the suspension wheel set 001 is hung on the track 101, the rollers 42 are attached to the inner side wall of the track 101.

[0053] like Figure 3 and Fig.19 As shown, in the actual production process of this embodiment, the positioning column 50 is integrally injection-molded on the housing 10 to optimize the product structure, reduce production processes, and improve production efficiency.

[0054] More specifically, in order to facilitate the assembly of the column 41 in this embodiment, the column 41 includes a connecting column 41.1 equipped with a roller 42 and a base column 41.2 provided with a through hole, the lower end of the connecting column 41.1 is inserted and fixed in the through hole of the base column 41.2, and the arc groove h is arranged on the surface of the base column 41.2.

[0055] There are two suspension assemblies 40 , and a linkage component connects the two suspension assemblies 40 . The operating unit drives the two suspension assemblies 40 to perform linear motion simultaneously through the linkage component.

[0056] The control part can be a push piece, a sliding piece or a rod-shaped part 61. Specifically, the user can apply external force to press the push piece to drive the linkage part to move, thereby driving the suspension component 40 to move up and down. Of course, as a change, the control part can also be a sliding piece, that is, the user uses the sliding sliding piece to drive the linkage part; the above technical means is to point out that the control part in this embodiment is only an overview, as long as the control part can control the linkage part to drive the suspension component 40 to move up and down. In this technical solution, the case where the rod-shaped part 61 is used as the control part is described in detail, as follows:

[0057] like Fig.18 As shown, the operating portion is preferably a rod-shaped component 61 , and the linkage component is a linkage plate 70 , and the linkage plate 70 is driven by the rod-shaped component 61 exposed outside the housing 10 .

[0058] Specifically, two ends of the linkage plate 70 are provided with snap-fits 71 , and the column 41 is provided with a positioning groove 41 . 3 . The snap-fits 71 on the linkage plate 70 are snapped into the positioning groove 41 . 3 of the column 41 .

[0059] The rod-shaped component 61 is preferably an L-shaped rod-shaped component, the turning portion of which is axially connected to the inner side of the shell 10, the first arm of the L-shaped rod-shaped component is the wrench portion 61.1, and the second arm of the L-shaped rod-shaped component is the force arm 61.2, on which a push rod 04 is provided that can move the linkage plate 70 upward.

[0060] The base column 41.2 comprises an upper column 01 for the connecting column 41.1 to be inserted, an intermediate column 02 provided with an arc groove h, and a lower column 03. The outer diameter of the intermediate column 02 is greater than the outer diameters of the upper column 01 and the lower column 03.

[0061] like Figures 11 to 13 As shown, a compression spring 60 is sleeved on the lower column 03, the lower end of the compression spring 60 presses on the linkage plate 70, and the upper end of the compression spring 60 presses on the limit plate 11 on the housing 10. Under the action of the limit plate 11 and the linkage plate 70, the compression spring 60 is in a certain degree of compression, so that the compression spring 60 has elastic force to make the column 41 have a tendency to move downward, so that the roller 42 is closely attached to the side wall of the track 101.

[0062] Here, it is necessary to elaborate on the compression spring 60 in detail that, in the first state, the compression spring 60 is in a normal state, but in this normal state, the compression spring 60 still has a certain elastic force; when the user operates the rod-shaped component 61, so that the top rod 04 presses the linkage plate 70 upward, so that the linkage plate 70 presses the compression spring 60 upward to make the compression spring 60 in a compressed state, the suspension wheel set 001 is in the second state at this time, and the operator can quickly insert the suspension wheel set 001 into the track 101; then, the applied external force is removed, and the column 41 moves downward under the action of the rebound force of the compression spring 60, and the suspension wheel set 001 rotates to the first state. And in this state, under the action of the rebound force of the compression spring 60, the roller 42 on the suspension wheel set 001 is tightly attached to the lower surface of the inner side wall of the track 101, so that the suspension state of the suspension wheel set 001 is more stable.

[0063] Therefore, the compression spring 60 in this embodiment can not only control the downward movement of the column 41, but also make the suspension state of the suspension wheel set 001 more stable. This technical means further reflects the creativity of this technical solution.

[0064] How the control unit in the curtain booster 103 controls the column 41 to rotate while moving up and down is described in detail as follows:

[0065] The curtain booster 103 includes a direction-changing component for rotating the suspension component 40 to a certain angle, and the direction-changing component includes a control unit exposed to the housing 10 and a rotation control component connected to the two columns 41. In addition to the above, the control unit can control the column 41 to move up and down through the linkage plate, and of course the linkage control mode between the control unit and the column 41 can also be a rotation control mode.

[0066] As for the rotation control assembly, it can be a linkage gear assembly, and the control part is connected to each column 41 through the linkage gear assembly. Of course, the control part at this time can also be a pressing type, a sliding type or other methods, as long as the control part can control the linkage gear assembly to rotate, the linkage gear assembly after activation can control the column 41 to move up and down.

[0067] Of course, it needs to be reiterated in this embodiment that the rotation control component in the present technical solution mainly includes a positioning column 50 provided on the shell 10 and an axially extending arc groove h provided on the outer wall of the column 41, and the positioning column 50 is inserted into the arc groove h; when the column 41 moves up and down, the column 41 rotates at a certain angle.

[0068] More specifically, if Figure 16 to Figure 17 As shown, for the suspension wheel set 001, an axle seat a is provided at the upper end of the column 41, and the suspension wheel set includes rollers 42 axially connected to both sides of the axle seat a. Specifically:

[0069] A rotating shaft b is passed through the shaft seat a, and the rollers 42 on both sides are sleeved on the rotating shaft b. Limiting members are provided at both ends of the rotating shaft b to limit the rollers 42 on the rotating shaft b.

[0070] A compression spring 60 is sleeved on the column 41 , and the compression spring 60 is used to keep the running wheel 20 under compression on the track 101 .

[0071] The lower ends of the two columns 41 are connected with a linkage plate 70 . A limit plate 11 is provided on the housing 10 . The compression spring 60 is located between the linkage plate 70 and the limit plate 11 .

[0072] The housing 10 includes a front housing 12 and a rear housing 13 made of plastic, and the front housing 12 and the rear housing 13 are fastened by a screw assembly.

[0073] Regarding how the curtain booster 103 moves while being suspended by the suspension assembly 001, the specific implementation means are as follows:

[0074] In actual use, the hanging wheel set 001 on the curtain booster 103 is pressed down on the inner surface of the track 101, and the running wheels of the curtain booster 103 move along the lower surface of the track 101, and the curtain booster 103 pushes the curtain 102 to move.

[0075] More specifically, as described above, the curtain booster 103 in this embodiment includes a shell 10, a suspension assembly 40 and a running wheel 20 driven by a motor 30, wherein a portion of the running wheel 20 is exposed at the upper portion of the shell 10 to contact the lower surface f2 of the track 101, and the suspension assembly 40 includes two suspension components T, wherein the suspension component T includes a suspension wheel group 001 extending out of the shell 10 and located in the track 101, and a column 41 extending into the shell 10, wherein a compression spring 60 is provided inside the column 41 for applying a downward force to the column 41, wherein the compression spring 60 presses the suspension wheel group 001 downwardly against the inner surface f1 of the track 101 and presses the running wheel 20 upwardly against the lower surface f2 of the track 101.

[0076] Specifically, in the actual installation process, in the first state, the compression spring 60 is in a normal state, but in this normal state, the compression spring 60 still has a certain elastic force; when the user operates the rod-shaped component 61, the top rod 04 presses the linkage plate 70 upward, so that the linkage plate 70 presses the compression spring 60 upward to make the compression spring 60 in a compressed state, the suspension wheel set 001 is in the second state at this time, and the operator can quickly insert the suspension wheel set 001 into the track 101; then, the applied external force is removed, and the column 41 moves downward under the action of the rebound force of the compression spring 60, and the suspension wheel set 001 rotates back to the first state. And after this state is restored, the compression spring 60 still has a certain elastic force, and the roller 42 on the suspension wheel set 001 is pressed down tightly on the inner surface f1 of the track 101, so that the suspension state of the suspension wheel set 001 is more stable. And at this time, according to the preset vertical spacing between the running wheel 20 and the roller 42, the running wheel 20 just presses up on the lower surface f2 of the track 101.

[0077] A limit plate 11 is disposed in the housing 10 , and a linkage plate 70 is disposed at the lower ends of the two columns 41 . Both ends of the compression spring 60 are pressed between the limit plate 11 and the linkage plate 70 , so that the compression spring 60 applies a downward force to the column 41 .

[0078] The output end of the motor 30 is connected to a gearbox, and the output shaft of the gearbox drives the walking wheel 20 .

[0079] The curtain booster 103 further includes a control circuit 002 for communicating with the motor 30 and a rechargeable battery 003 for powering the motor 30 .
