Description

Technical Field

[0001] The utility model belongs to the technical field of sunshade products, and in particular relates to an electric folding sunshade skylight transmission system. Background Art

[0002] Folding sunshade devices are important sunshade and isolation protection products. Traditional fixed sunshade and protection facilities have many limitations and cannot meet people's flexible and changeable use needs. For example, under different time and weather conditions, people need to adjust the angle and range of sunshade. Therefore, a foldable sunshade device is derived, which can be opened and closed appropriately according to the specific environment.

[0003] With the continuous advancement of science and technology, people have higher and higher requirements for the convenience and intelligence of life. The folding sunshade device can use a miniaturized motor for electric drive adjustment, achieving smoother, faster and more convenient deployment and folding, as well as adjusting the appropriate opening and closing range; through advanced control systems, it can also realize remote control, timing operation, automatic sensing and other functions.

[0004] In an electric folding sunshade device, a structural system needs to be designed to realize the folding operation of the sunshade to achieve smooth and safe opening and closing operation. The structure of the folding operation system directly affects the control flexibility, service life and cost of the sunshade device.

[0005] The existing folding operation system uses a motor to drive a rotating rod, which in turn drives a transmission belt (such as a belt, chain, rope, etc.) to pull the end pulley of the sun visor to move, thereby realizing the folding and opening of the sun visor. For example, patent CN202064802U discloses an electric folding external sunshade anti-theft device for windows, which uses a transmission belt or a transmission rope for transmission.

[0006] The existing folding operation system has the following problems:

[0007] (1) The transmission stroke is long, and the transmission distance of the transmission belt is the length of the two ends of the belt, so the opening and closing is slow and time-consuming.

[0008] (2) After long-term use, the transmission belt is prone to wear, aging, and breakage, and it is difficult to increase its service life; or the transmission belt derails and the folding function fails.

[0009] (3) After long-term use, the transmission belt is prone to poor contact with the sun visor, causing the transmission belt to idle and the traction and folding function to fail.

[0010] (4) The pulley has a long movement stroke. The movement distance of the pulley is the distance between two sun visors. The longer the movement stroke of the pulley, the easier it is to wear and damage. The opening and closing is slower and takes a long time.

[0011] (5) The transmission stroke is long, which makes the motor energy consumption cost high; frequent maintenance and repairs will lead to high maintenance costs.

[0012] Therefore, it is necessary to continuously develop and improve a more convenient, flexible and durable folding operation system to reduce maintenance and repair costs, and improve people's usage experience and quality of life. Utility Model Content

[0013] In view of the above problems existing in the existing belt-driven folding operation system, the utility model provides an electric folding sunshade transmission system, in which an intermediate guide rail is arranged on the inner center line of the guide rail frame, and pulleys are arranged at the centers of both ends of each sunshade. A push rod is used to drive a pulley (driving wheel) to slide along the intermediate guide rail, thereby driving the folding sunshade to extend and retract and other pulleys to slide, so as to realize faster and more reliable opening and closing of the folding sunshade, extend the service life, and reduce the cost. The specific technical scheme is as follows:

[0014] An electric folding sunshade awning transmission system comprises a rectangular frame, the rectangular frame is composed of upper and lower guide frame connecting grooves 1 and left and right guide frames 2, a folding sunshade 4 is arranged in the rectangular frame, the folding sunshade 4 comprises a plurality of visors, and adjacent visors are rotatably connected by a rotating shaft; one telescopic end of the folding sunshade 4 is fixedly connected to a guide frame connecting groove 1, and the other telescopic end of the folding sunshade 4 is a free end; an intermediate guide rail 2.1 is arranged on the inner center line of the guide frame 2; the folding sunshade 4 Pulleys 6 are provided at the center of both ends of each baffle, and the pulleys 6 slide along the middle guide rail 2.1; all the pulleys 6 moving in each middle guide rail 2.1 constitute a pulley block, and one of the pulleys 6 in the pulley block is a driving wheel; an "I"-shaped through hole is also provided at the center line of the guide rail frame 2, and the length of the "I"-shaped through hole corresponds to the sliding travel distance of the driving wheel; a push rod driving device 5 is fixedly installed on the outer side of the guide rail frame 2, and the shaft of the driving wheel passes through the "I"-shaped through hole and is connected to the front end of the push rod of the push rod driving device 5.

[0015] In the above technical solution, the telescopic movement of the push rod of the push rod driving device 5 drives the driving wheel to slide along the middle guide rail 2.1, thereby driving the folding sun visor 4 to telescope and the pulley block to slide.

[0016] In the above technical solution, the outer side of the guide rail frame 2 is covered with a guide rail frame side baffle 3 for covering the push rod driving device 5 .

[0017] In the above technical solution, the cross-section of the guide rail frame connecting groove 1 is in a "匚" shape.

[0018] In the above technical solution, the cross section of the guide rail frame 2 is an “I” shape.

[0019] In the above technical solution, the width of the "one"-shaped through hole is smaller than the track width of the middle guide rail 2.1.

[0020] In the above technical solution, the inner side of the guide rail frame 2 is the side of the guide rail frame 2 facing the folding sunshade 4; the outer side of the guide rail frame 2 is the side of the guide rail frame 2 facing away from the folding sunshade 4.

[0021] In the above technical solution, the sliding stroke distance of each pulley 6 is the up and down width of one sunshade panel.

[0022] In the above technical solution, the number of the push rod driving devices 5 is two, and one push rod driving device 5 is respectively installed on the outer side of each guide rail frame 2; the two push rod driving devices 5 are symmetrically arranged left and right; a "one"-shaped through hole is opened at the midline of each guide rail frame 2, and the two "one"-shaped through holes are symmetrically arranged left and right.

[0023] In the above technical solution, the push rod driving device 5 includes but is not limited to a push rod motor.

[0024] In the above technical solution, the electric folding sunshade curtain transmission system is used for sunshading and isolation protection of the ceiling, window or door.

[0025] An electric folding sunshade curtain transmission system provided by the present utility model has the following beneficial effects compared with the prior art:

[0026] First, the present utility model uses the push rod of the push rod motor to drive the driving wheel to slide along the middle track, and then drives the folding sunshade to expand and contract and other pulleys to slide. The traditional transmission belts (such as belts, chains, ropes, etc.) are omitted, and problems such as wear, aging, breakage, and derailment of the transmission belts can be completely avoided. The push rod transmission is not easily damaged, has a longer service life, and greatly reduces the maintenance and repair costs.

[0027] Second, the folding sunshade includes a plurality of sunshade panels. The sliding stroke distances of the push rod, the driving wheel and other pulleys are the up and down width of one sunshade panel, which greatly shortens the sliding stroke of the pulleys. The pulleys are not easily worn and have a longer service life.

[0028] Third, since the sliding strokes of the push rod and the pulleys are very short, the opening and closing of the entire folding sunshade can be achieved with a small sliding floating amount. The opening and closing are fast, time-consuming is short, and it is easy to control.

[0029] Fourth, the shaft rod of the driving wheel passes through the "one"-shaped through hole and is connected to the front end of the push rod of the push rod driving device. The connection is simple and firm, and the folding function is not likely to fail.

[0030] Fifth, the push rod stroke of the push rod driving device is very short, which can effectively reduce the energy consumption of the motor; and it saves traditional components such as transmission belts and reduces the manufacturing cost.

[0031] 6. Push rod drive can also avoid the running-in noise caused by long-term wear of the transmission belt.

[0032] 7. Setting the pulley at the center of both ends of the baffle and setting the guide rail in the middle of the guide rail frame can balance the force from the baffle on both sides of the pulley, making the pulley balanced and more durable.

[0033] 8. Designing two left and right push rod drive devices to make the driving wheels on both sides slide at the same time can prevent the folding sun visor from being unevenly stressed, thereby preventing the folding sun visor from being skewed or stuck, making the folding sun visor extend and close more smoothly.
