For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0034] The present application will be described in detail below with reference to the accompanying drawings and optional embodiments.

[0035] Figure 1 is a perspective view of a vertical curtain of the present application, Figure 2 is a cross-sectional view of a vertical curtain of the present application, as shown in Figures 1-2 The present application discloses a vertical curtain, which comprises a guide rail 110, a special-shaped clamping piece 130, a hanging wheel 140 and a light adjusting shaft 114.

[0036] The guide rail 110 comprises a guide rail body 111, which comprises a hanging wheel mounting area 112; the special-shaped clamping piece 130 is arranged outside the guide rail 110 and is used to fix a curtain leaf 150; the hanging wheel 140 is arranged in the hanging wheel mounting area 112 and can slide on the guide rail body 111, and the hanging wheel 140 is used to suspend the special-shaped clamping piece 130; the light adjusting shaft 114 is arranged in the hanging wheel mounting area 112 and passes through the hanging wheel 140, and the light adjusting shaft 114 is used to control the rotation of the special-shaped clamping piece 130.

[0037] The hanging wheel mounting area 112 is provided with a lateral opening 115, and the hanging wheel 140 is connected to the special-shaped clamping piece 130 after extending outward from the lateral opening 115; the rotation axis of the special-shaped clamping piece 130 is located outside the guide rail body 111.

[0038] The application re-designs the guide rail 110. Compared with the conventional way of connecting the curtain leaf 150 at the bottom of the guide rail 110, the guide rail 110 of the application is opened at the side, and the special-shaped clamping piece 130 is connected from the side through the hanging wheel 140. The rotation axis of the special-shaped clamping piece 130 during rotation is located outside the track main body. In this way, even if the curtain leaf 150 higher than the bottom of the guide rail 110 is arranged on the special-shaped clamping piece 130, the maximum rotation angle can still reach 180 degrees, and the vertical curtain 100 still has the light adjustment function. The guide rail 110 designed in the application can install the curtain leaf 150 higher than the bottom of the guide rail 110, thereby realizing the function of hiding the guide rail 110 and improving the aesthetics of the vertical curtain 100.

[0039] The special-shaped clamping piece 130 has a certain gap between the bottom of the guide rail 110, and generally the width of the clamping piece is greater than the width of the guide rail 110. The special-shaped clamping piece 130 can be used to clamp the curtain leaf 150 higher than the lowest position of the guide rail main body 111, so as to block the guide rail main body 111 through the curtain leaf 150.

[0040] It can be understood that if the guide rail 110 is opened at the bottom, even if the hook 143 is arranged at the outermost position in the guide rail main body 111, under the projection of gravity, the rotation axis of the clamping piece still falls within the projection of the guide rail main body 111, resulting in that when the clamping piece installs the curtain leaf 150 higher than the bottom of the guide rail 110, the clamping piece cannot be adjusted to the angle parallel to the guide rail main body 111, that is, the light adjustment angle of 180 degrees, resulting in that the vertical curtain 100 cannot realize the full shading function. The rotation axis of the special-shaped clamping piece 130 of the application is arranged outside the guide rail main body 111, and even if the curtain leaf 150 higher than the guide rail main body 111 is arranged, it will not interfere with the guide rail main body 111. It can be understood that the outside of the track main body defined in the application is that when the length direction of the special-shaped clamping piece 130 is parallel to the guide rail main body 111, a gap is arranged between the special-shaped clamping piece 130 and the guide rail main body 111, and this position is defined as the outside of the guide rail main body 111. Specifically, the rotation axis of the special-shaped clamping piece 130 is located between the guide rail main body 111 and the second clamping part.

[0041] Figure 3 It is a schematic view of a hanging wheel of the application, which is combined with Figures 1-2As shown, the application also discloses a hanger wheel 140, which comprises a hanger wheel body 141, a hanger wheel body extension 142, and a hanger hook 143 for hanging the special-shaped clamping piece 130; the dimming shaft 114 is arranged through the hanger wheel body 141 to drive the hanger hook 143 to rotate to control the rotation of the special-shaped clamping piece 130; the hanger wheel body 141 is arranged in the guide rail body 111, and the hanger wheel body 141 extends outward from the lateral opening 115 to form the hanger wheel body extension 142, the hanger hook 143 is arranged in the hanger wheel body extension 142 and extends outward to connect the special-shaped clamping piece 130; the hanger hook 143 is arranged outside the lateral opening 115.

[0042] The hanger wheel body 141 is provided with a dimming hole 145, and a worm gear is arranged in the dimming hole 145. The worm gear is a hollow columnar structure. The dimming shaft 114 passes through the worm gear, and the cross-sectional shape of the dimming shaft 114 is consistent with that of the worm gear. For example, the dimming shaft 114 is quadrangular or hexagonal, and the worm gear is also quadrangular or hexagonal. The outer wall of the worm gear is provided with a thread, and the upper part of the hanger hook 143 is a worm. The worm gear and the worm are matched to realize the rotation of the hanger hook 143. The rotation axis of the worm gear is along the length direction of the guide rail 110, and the rotation axis of the worm is parallel to the direction of gravity.

[0043] In the scheme, the hanger wheel body extension 142 is completely arranged outside the guide rail body 111, the bottom of the hanger wheel body extension 142 is provided with a through hole, the worm part of the hanger hook 143 is arranged inside the hanger wheel body extension 142, and the hook part of the hanger hook 143 is arranged outside the hanger wheel body extension 142.

[0044] Generally, the rotation axis of the special-shaped clamping piece 130 is the hanger hook 143. The dimming shaft 114 drives the worm to rotate to realize the rotation of the special-shaped clamping piece 130. The special-shaped clamping piece 130 also rotates, and the rotation axis is consistent with the hanger hook 143. When the hanger hook 143 and the worm are not on the same straight line, the special-shaped clamping piece 130 is not rotated, and the dimming system of the vertical curtain 100 is relatively complex.

[0045] Specifically, the hanger wheel mounting area 112 is provided with a first support position 123 for providing upward support force for the hanger wheel 140 and a second support position 124 for providing downward limiting position for the hanger wheel 140, and the second support position 124 is arranged on the side of the first support position 123 away from the lateral opening 115. In this scheme, since the hook 143 is arranged on the outer side of the guide rail body 111, the curtain leaf 150 pulling force received by the hanger wheel 140 is on the outer side of the guide rail body 111, in order to balance the pulling force, a downward limiting force needs to be applied on the other side of the hanger wheel 140 away from the hook 143, that is, the second support position 124 is used to prevent the hanger wheel 140 from being stuck in the guide rail body 111 due to unbalanced force from the lateral opening 115.

[0046] Figure 4 is a schematic view of a guide rail of a vertical curtain of the present application, as shown in Figure 4 The present application discloses a guide rail 110, which comprises a hanger wheel mounting area 112, the hanger wheel mounting area 112 comprises a first top plate 120, a first side plate 121 and a first bottom plate 122, one end of the first side plate 121 is connected to one end of the first top plate 120, the other end of the first side plate 121 is connected to one end of the first bottom plate 122, and the other end of the first bottom plate 122 and the other end of the first top plate 120 form a lateral opening 115.

[0047] The first support position 123 comprises a first support plate, which is parallel to the first side plate 121 and arranged on the first bottom plate 122, and the hanger wheel 140 is provided with a first limiting portion 144 corresponding to the first support plate. Figure 1 In the figure, only the first support position 123 is arranged at the bottom of the hanger wheel mounting area 112, that is, a bottom support mode is adopted. In the field of vertical curtains 100, generally speaking, the bottom support mode is simpler, more stable and has low manufacturing cost.

[0048] The end of the first support plate close to the hanger wheel 140 is provided with a protrusion 127, the first limiting portion 144 is provided with a recess 128, the protrusion 127 is arranged in the recess 128 and used for providing upward and downward limiting position for the hanger wheel 140. The protrusion 127 and the recess 128 on the first support plate cooperate to enable the first support position 123 to provide support force when the guide rail 110 is placed in the anti-gravity direction, which is generally used for displaying the running of the track on the exhibition to prevent the hanger wheel 140 from being unsupported when placed in the anti-gravity direction.

[0049] The second support position 124 is a second support plate arranged on the first top plate 120 and used for abutting against the hanging wheel 140. Of course, in the demonstration, the guide rail 110 is placed upside down, and the second support position 124 can provide a certain support force for the hanging wheel 140.

[0050] Specifically, the first side plate 121 is further provided with a third support position 125 used for providing upward limiting for the hanging wheel 140. The third support position 125 can provide a certain support force for the hanging wheel 140 when the guide rail 110 is placed in the running mode. When the guide rail 110 is placed in the anti-gravity direction, the third support position 125 has the same function as the second support position 124 and is used for limiting the hanging wheel 140.

[0051] The first support position 123, the second support position 124 and the third support position 125 can be respectively provided with a mute sliding strip to keep better running.

[0052] The hanging wheel mounting area 112 is a semi-enclosed structure of the lateral opening 115. The lower part of the lateral opening 115 can be further provided with an extension of the first bottom plate 122, that is, an upward extension to abut against the hanging wheel body 141 and provide a certain support force for the hanging wheel body 141. Similarly, the upper part of the lateral opening 115 can also be provided with an extension to limit the hanging wheel 140. However, for the electric vertical curtain 100 of the present application, a gap is generally provided between the hanging wheel 140 and the first top plate 120 at the upper part of the lateral opening 115 to provide smooth running.

[0053] Specifically, the first support plate and the first bottom plate 122 form a groove 126 near the end of the lateral opening 115, and the light adjusting shaft 114 is in the same vertical direction as the groove 126. The light adjusting shaft 114 has a certain deformability. For a larger guide rail 110, when all the hanging wheels 140 are received on both sides, the middle part of the light adjusting shaft 114 cannot be supported and thus falls into the groove 126 to accommodate the light adjusting shaft 114.

[0054] Based on the design of Figure 1 , the adjacent hanging wheels 140 can be connected by a rope or a connecting piece, and the drive of the light adjusting shaft 114 can be manually driven by providing a driving structure on both sides.

[0055] In the manual vertical curtain 100, the first bottom plate 122 can be set as an arc-shaped plate, which gradually extends upward from the direction of the first side plate 121 to the lateral opening 115, forming a cavity 129 between the first side plate 121, the hanging wheel 140, the first support plate and the bottom plate. The cavity 129 can be used to store ropes or cables or pull ropes.

[0056] For this purpose, based on the above design, the application further discloses an electric vertical curtain 100, which is mainly different from the manual vertical curtain 100 in that it is driven by a mechanism, so that the transmission mechanism part is different. However, the structure of the hanging wheel mounting area 112 is basically the same and can be completely applicable to the electric vertical curtain 100. The above-mentioned contents will not be repeated hereinafter.

[0057] Figure 5 is a perspective view of an angle of an electric vertical curtain according to the application, Figure 6 is another perspective view of an angle of an electric vertical curtain according to the application, Figure 7 is a cross-sectional view of an electric vertical curtain according to the application, Figure 8 is a cross-sectional view of a guide rail of an electric vertical curtain according to the application.

[0058] Referring to Figures 5-8 , the application discloses an electric vertical curtain 100 and a guide rail 110 thereof, which comprises a guide rail 110, a synchronous belt, a hanging wheel 140, a light adjusting shaft 114, a clamping piece and a driving mechanism. The guide rail 110 comprises a guide rail body 111, which comprises a synchronous belt mounting area 113 and a hanging wheel mounting area 112, the synchronous belt mounting area 113 being arranged above the hanging wheel mounting area 112; a synchronous belt is arranged in the synchronous belt mounting area 113, which drives the hanging wheel 140 to slide on the guide rail body 111; the hanging wheel 140 is arranged in the hanging wheel mounting area 112 and can slide on the guide rail body 111, and is used to suspend the special-shaped clamping piece 130; the light adjusting shaft 114 is arranged in the hanging wheel mounting area 112 and passes through the hanging wheel 140, and is used to control the rotation of the special-shaped clamping piece 130; wherein the hanging wheel mounting area 112 is provided with a lateral opening 115, and the hanging wheel 140 is connected to the special-shaped clamping piece 130 after extending outward from the lateral opening 115; the rotation axis of the special-shaped clamping piece 130 is located outside the guide rail body 111, and the synchronous belt and the light adjusting shaft 114 can be driven by a driving mechanism.

[0059] The first top plate 120 is the bottom plate of the synchronous belt installation area 113. The driving mode of the vertical curtain 100 can be divided into an opening and closing driving mode and a light adjustment driving mode. In the opening and closing driving mode, the two ends of the synchronous belt are respectively provided with a driven gear and a driving gear, and the synchronous belt is moved under the driving of the driving gear. The synchronous belt is connected to a hanging wheel 140 at one end through a trolley or directly, and drives the hanging wheel 140 to slide on the guide rail body 111. In the light adjustment driving mode, the light adjustment shaft 114 rotates, drives the hanging hook 143 to rotate through a worm and gear mode, and the hanging hook 143 is generally arranged in parallel to the direction of gravity. Here, the hanging wheel 140 rotates around the central axis in the direction of gravity as the rotation axis, drives the clamping piece below the hanging hook 143 to rotate, and thus realizes the light adjustment angle control of the curtain leaf 150. For example, when the curtain leaf 150 is parallel to the light entering direction, it is the maximum light adjustment angle, and the light transmittance is the largest. When the curtain leaf 150 is perpendicular to the light entering direction, it is the minimum light adjustment angle, and the light transmittance is the smallest. It can be understood that the light adjustment shaft 114 rotates at the same time, and the hanging wheel 140 can also move in the guide rail body 111, and the two do not interfere with each other, that is, the opening and closing can be realized when the light adjustment is realized, and the light adjustment can be realized when the opening and closing is realized.

[0060] It can be understood that in the scheme of driving the trolley through the synchronous belt and driving the hanging wheel 140 through the trolley, the trolley is arranged at the cavity 129 between the synchronous belts, and this part is not improved in the application, and will not be described here.

[0061] It can be understood that the opening and closing driving mode and the light adjustment driving mode of the manual vertical curtain 100 are the same except that they are manual and do not use synchronous belts. It can be understood that the electric vertical curtain 100 can also be provided with a manual driving mode.

[0062] It is worth mentioning that, unlike the manual vertical curtain 100, the second support position 124 in the embodiment is arranged on the first side plate 121, and the first top plate 120 is provided with an opening, which communicates the synchronous belt installation area 113 and the hanging wheel installation area 112.

[0063] Figure 9 FIG. 1 is a perspective view of an angle of a second electric vertical curtain according to the application, Figure 10 FIG. 2 is a sectional view of the second electric vertical curtain according to the application, Figure 11 FIG. 3 is a schematic view of a hanging wheel of the second electric vertical curtain according to the application.

[0064] The difference between the embodiment and the previous electric vertical curtain is that the first support position 123 and the second support position 124 inside are different. The first support position 123 is not provided on the first bottom plate 122, but is replaced by a support rod 123 provided along the length direction of the guide rail. The support rod 123 is limited by the recess 128 of the hanging wheel, is fixed on both sides of the guide rail, and is formed of a hard material. In the embodiment, the upward support of the hanging wheel is supported by the third support position 125 and the end of the first bottom plate. The third support position 125 is a part of the first bottom plate 122. The part of the first bottom plate 122 close to the first side plate 121 is the first support position. Another part has an outwardly protruding arc surface, forms a cavity below the light adjusting shaft 114, and is used for bearing the deformed part of the light adjusting shaft 114. The end of the first bottom plate supports between the main body of the hanging wheel and the extension of the main body of the hanging wheel. A convex and concave matching structure is arranged at the position. In combination with the action of the support rod 123, the problem of unsmooth operation of the hanging wheel when the guide rail is inverted is solved.
