Description

Technical Field

[0001] The invention relates to the field of building materials, and in particular to a modular sunshade. Background Art

[0002] Sunshade products can act as curtains to block the sun, and can also be closed to block the wind. Currently, electric sunshades only have two forms: sliding up and down to open and close, or rotating the sunshade itself to open and close. Sunshades that slide up and down to open and close are all descending shades. If you want to achieve half-shading, you can only block the upper half and open the lower half. Sunshades that rotate to open and close cannot be fully opened. Even if the sunshade is rotated to be perpendicular to the window, the sunshade will always interfere with the line of sight. In addition, if the same sunshade product needs to achieve independent adjustment of the degree of shading at different heights, existing sunshade products cannot do this.

[0003] It is not difficult to see that the existing technology still has certain defects. Summary of the invention

[0045] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be clearly and completely described in combination with the embodiments of the present invention and the accompanying drawings. It should be noted that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0046] Embodiment 1

[0047] See also Figures 1 to 3 The embodiment of the present invention provides a modular sunshade, including a lifting drive system 1, a feeding system 2, a guide rail 3, a sunshade module 4 and a connecting member 5; the guide rail 3 is fixedly arranged on both sides, and a lifting rail 6 is provided on the guide rail 3 corresponding to the sunshade module 4, and the lifting rail 6 extends in an L shape, and a horizontal rail 8 extending horizontally and a vertical rail 7 connected to the horizontal rail 8 are provided at the bottom thereof; the sunshade module 4 includes a frame 9, a sunshade sheet 10 and a rotating drive system; the two sides of the frame 9 of each sunshade module 4 are respectively slidably connected to the lifting rail 6, so that the sunshade module 4 is horizontally arranged along the horizontal rail 8 when stored, and moves vertically along the vertical rail 7 during the lifting process, The feeding system 2 is installed at the bottom of the guide rail 3, corresponds to the horizontal rail 8 and is detachably connected to the sunshade module 4, driving the sunshade module 4 arranged along the horizontal rail 8 to feed forward or backward; the sunshade sheets 10 are arranged and installed in the frame 9, and are rotationally connected to the frame 9, and the rotation drive system is transmission connected to each sunshade sheet 10; a connecting member 5 is provided on the top of each sunshade module 4, and during the lifting process, the bottom of the sunshade module 4 arranged in the front is connected to the connecting member 5 of the adjacent sunshade module 4 arranged in the back; the lifting drive system 1 is transmission connected to the first sunshade module 4, driving the sunshade module 4 to lift and lower.

[0048] The sunshade product of the present invention divides a sunshade into multiple independently working sunshade modules 4 according to different heights, and the structures of each sunshade module 4 are basically the same. Except for the sunshade module 4 arranged at the end, the other sunshade modules 4 arranged in the front need to be lifted to different degrees.

[0049] When there is no need for shading or wind and rain protection, the sunshade modules 4 can be folded down and arranged in a front-to-back state, so that the view of the wide space above is not blocked. When shading or wind and rain protection is required, the lifting drive system 1 will drive the first sunshade module 4 to lift upward. Since the sunshade modules 4 can be detachably connected through the connecting member 5, the sunshade modules 4 will be pulled by each other through the connecting member 5 and lifted one by one. The opening and closing of the sunshade sheet 10 of each sunshade module 4 is realized by each independent rotation drive system, so that the light transmittance can be independently adjusted according to different heights.

[0050] The lifting of each sunshade unit needs to be stabilized by the lifting rail 6 on the guide rail 3, and ensure that the motion trajectory meets the requirements. Preferably, the horizontal rail 8 is provided with two parallel rails corresponding to the upper and lower ends of the sunshade module 4; the top and bottom ends of the frame 9 of the sunshade unit are slidably connected to the lifting rail 6 through sliding components, and the top and bottom ends correspond to the two upper and lower horizontal rails 8.

[0051] That is, for each sunshade module 4 that needs to be lifted, it is connected to the lifting track 6, and its movement trajectory also follows the lifting track 6. The sunshade module 4 slides horizontally along the horizontal track 8 when stored, and slides up and down along the vertical track 7 when lifted. During the lifting movement, the connecting components 5 between two adjacent sunshade modules 4 arranged vertically are engaged to generate a traction effect.

[0052] See Figure 4 More specifically, the connecting member 5 is hook-shaped and is installed on both sides of the top of the frame 9; and connecting parts 11 that cooperate with the connecting member 5 are fixedly provided on both sides of the bottom end of the frame 9, so that the connecting member 5 is hooked on the connecting part 11 during the lifting process.

[0053] During the lifting process, the lifting drive system 1 first lifts the first sunshade module 4 upwards, and after it is lifted to a unit height, the feeding system 2 cooperates to push the second sunshade module 4 forward to just below the first sunshade module 4, and enters the vertical rail 7. At the same time, the connecting member 5 of the second sunshade module 4 is just hooked on the connecting part 11 of the first sunshade module 4, so that the two sunshade modules 4 are connected. The first sunshade module 4 continues to be lifted, which will drive the second sunshade module 4 to be lifted. And so on, the sunshade modules 4 will be lifted one by one. In theory, as long as the power of the lifting drive system 1 is sufficient, multiple sunshade modules 4 can be driven to lift.

[0054] The descending and folding process of the sunshade module 4 is the reverse process of the above process, which will not be described in detail here.

[0055] As for the feeding system 2, its mechanical power structure preferably adopts chain drive, which is not only highly reliable but also can be separated from the sunshade module 4 when it is lifted and reengaged with it when it is lowered.

[0056] Specifically in this embodiment, the feeding system 2 includes a feeding transmission chain 13, a feeding sprocket 14, a feeding motor (not shown), and a feeding synchronization shaft (not shown); the feeding motor is installed at the bottom of the guide rail 3, and the feeding synchronization shaft is rotatably connected between the bottoms of the two guide rails 3, and is connected to the feeding motor in a transmission manner; the bottom of the guide rail 3 is provided with two groups of front and rear feeding sprockets 14 in a horizontal direction, and both ends of the feeding synchronization shaft are connected to the same group of feeding sprockets 14 located in the front or rear, and the feeding transmission chain 13 is wound around the front and rear feeding sprockets 14; the bottom of the frame 9 is fixedly provided with a feeding tooth 15 that cooperates with the feeding transmission chain 13, so that when the sunshade module 4 descends to the bottom of the guide rail 3, the feeding tooth 15 engages with the feeding transmission chain 13 for transmission.

[0057] In this embodiment, the feed motor is a source power device independent of the lifting drive system 1, and the overall component arrangement is relatively simple. The feed motor and the lifting drive system 1 must work in coordination, so preferably, a detection switch (not shown) connected to the feed motor control is installed on the guide rail 3, so that when the sunshade module 4 is lifted by a unit height, the feed motor drives the feed system 2 to drive the sunshade module 4 to feed a thickness distance, so that the lifting drive system 1 and the feed system 2 work in coordination.

[0058] Depend on Figure 2 and Figure 4 It can be seen that the connection portion 11 mentioned above is very close to the transmission tooth, and the two can also be made into one component.

[0059] See also Figure 6 For the specific structure of each sunshade module 4, preferably, the frame 9 of the sunshade module 4 is composed of a top beam, a bottom beam and a side beam fixedly connected; the top beam and the bottom beam are horizontally arranged on both sides of the top and the bottom respectively, and the side beams are fixedly arranged on both sides of the top beam and the bottom beam; the sunshade sheet 10 is installed between the top beam and the bottom beam, and is rotatably connected to the top beam and the bottom beam; the rotation drive system is installed on the top beam or the bottom beam, and is transmission-connected to each sunshade sheet 10.

[0060] Among them, the top beam, bottom beam and side beam are very practical and are formed by profile processing, especially for the side beam, it is convenient to process the slide rail. And for the sunshade module 4 that needs to be lifted, this structure is conducive to the overall lightweight, thereby reducing the load of the lifting drive system 1.

[0061] See also Figure 6 Preferably, the rotation drive system of the sunshade module 4 includes an electric cylinder 18 and a synchronous connecting rod 19; the tail of the electric cylinder 18 is rotatably connected to the frame 9, and the telescopic end of the electric cylinder 18 is hinged to the synchronous connecting rod 19; the synchronous connecting rod 19 is transmission-connected to each sunshade sheet 10, so that the synchronous connecting rod 19 can drive all sunshade sheets 10 to rotate synchronously.

[0062] Since there may be a certain gap between the sunshade modules 4 after they are raised, in order to cover the gap to ensure beauty and to shield the gap, preferably, the bottom of the frame 9 of the sunshade module 4 is provided with an outer shielding piece 12 extending downward to shield, so that when the sunshade module 4 located in the front is lifted and stacked backward on the adjacent sunshade module 4 at the rear, the outer shielding piece 12 is set at the joint to shield. According to the requirements, the outer shielding piece 12 can be a non-rigid component to prevent the danger of shearing and pinching hands in individual cases.

[0063] It should be noted that the outer baffle 12 is not necessarily a component manufactured independently and installed at the bottom of the frame 9. It can be a part that is integrally arranged with the bottom beam of the frame 9. As long as it has the function of sealing the gap between adjacent sunshade modules 4, it should be regarded as the outer baffle 12 mentioned above.

[0064] See Figure 1 For the specific structure of the lifting drive system 1, it is preferred to adopt a chain transmission structure with strong load-bearing capacity and high reliability. Preferably, the lifting drive system 1 includes a lifting motor 22, a lifting synchronization shaft 23, a lifting sprocket 24, and a lifting transmission chain 25; the lifting motor 22 is installed on the top side between the guide rails 3, and is connected to the lifting synchronization shaft 23 in transmission; two upper and lower lifting sprockets 24 are respectively arranged along the axial direction of the guide rail 3, and the lifting transmission chain 25 is wound around the lifting sprocket 24, and the two ends of the lifting synchronization shaft 23 are respectively connected to the lifting sprockets 24 at the top of the two guide rails 3 in transmission, and the two lifting transmission chains 25 are respectively connected to the two sides of the first sunshade module 4, so that the lifting transmission chain 25 drives the sunshade module 4 to slide up and down.

[0065] In order to ensure that the sunshade module 4 does not fall down due to power failure of the lifting drive system 1 after being fully lifted, the lifting motor 22 needs to have a brake function.

[0066] See also Figure 7 For the sunshade sheets 10 of each sunshade module 4, in the closed state, they are preferably able to cooperate with each other to improve the sealing degree, thereby improving the shading, wind and rain protection effect. Therefore, the front side of one side of the sunshade sheet 10 is preferably provided with a connecting groove 20, and the back side of the other side is provided with a connecting flange 21 that cooperates with the connecting groove 20, so that when the sunshade sheets 10 are closed, the connecting flange 21 and the connecting groove 20 are engaged with each other to shield each other.

[0067] Embodiment 2

[0068] The only difference between this embodiment and the first embodiment is the transmission structure of the feeding system 2. In this embodiment, a transmission structure in which the feeding system 2 and the lifting drive system 1 are mechanically linked is adopted.

[0069] See also Figures 4 to 5 Specifically, the feeding system 2 includes a feeding transmission chain 13, a feeding sprocket 14, a feeding synchronization shaft and an intermittent transmission mechanism; the feeding synchronization shaft is rotatably connected between the bottoms of the two guide rails 3, and is connected to the lifting drive system 1 through an intermittent transmission mechanism; the bottom of the guide rail 3 is provided with two groups of front and rear feeding sprockets 14 in the horizontal direction, and the two ends of the feeding synchronization shaft are connected to the same group of feeding sprockets 14 located in the front or rear, and the feeding transmission chain 13 is wound around the front and rear feeding sprockets 14; the bottom of the frame 9 is fixedly provided with a feeding tooth 15 that cooperates with the feeding transmission chain 13, so that when the sunshade module 4 descends to the bottom of the guide rail 3, the feeding tooth 15 engages with the feeding transmission chain 13 for transmission.

[0070] In this embodiment, an intermittent transmission mechanism is used to link the lifting drive system 1 and the feeding system 2 through mechanical transmission. Therefore, the feeding system 2 does not need to be equipped with a feeding motor, nor does it need a detection switch to cooperate with electrical control.

[0071] Furthermore, the intermittent transmission mechanism includes a feed sheave 17, a crank 16 and a reduction gear set; the lifting drive system 1 is connected to the crank 16 through the reduction gear set, and the crank 16 is connected to the sheave 17 intermittently.

[0072] The groove wheel 17 mechanism is a typical intermittent transmission mechanism. When the crank 16 rotates continuously at a constant speed, the groove wheel 17 will be driven by the crank 16 to rotate intermittently according to a certain rhythm. The specific structure of the groove wheel 17 and the crank 16 is already very familiar to those skilled in the art, and their specific structure will not be described here. As long as the working rhythm can be calculated and matched, it can be achieved that every time the sunshade module 4 is raised by one unit height, the sunshade module 4 arranged behind will be fed forward by one unit thickness. The matching rhythm is controlled by the reduction gear set, and its transmission ratio is accurately calculated.

[0073] The modular sunshade provided by the present invention can be modularized according to height. When not in use, the sunshade module 4 can be stored downward to avoid blocking the line of sight. It can be raised when needed, and different modules can be opened and closed independently according to the height to adjust the light transmittance. The structure is simple, and multiple sunshade modules 4 are controlled by a lifting drive system 1. After being raised, the sunshade modules 4 are vertically stacked up and down with the same thickness, and the integrity is good. The shape design of the sunshade sheet 10 can be interlocked and shielded with each other after shielding, so as to achieve better shielding effect against wind and rain.

[0074] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
