With the development of society and the improvement of people's economic level, the popularity of cars is getting higher and higher. More and more families have private garages to park their cars. Since electric rolling shutter doors are easy to use, existing garage doors are generally equipped with electric rolling shutter doors. Rolling shutter doors are made of multi-jointed door panels connected in series. In a fixed slide, the door rotates up and down with the reel above the door as the center. Rolling shutter doors are usually widely used in shops. Rolling shutter doors play the role of horizontal separation like walls. They are composed of curtain plates, seat plates, guide rails, supports, reels, boxes, control boxes, rolling door machines, limiters, door lintels, manual quick-release switch devices, button switches and safety devices. They are generally installed in places where it is inconvenient to use walls for separation.

[0003] However, the existing garage door is not intelligent during use. Every time the rolling door is automatically opened, it will be fully opened to allow vehicles to enter and exit. The opening height of the garage door cannot be adjusted according to the height of the vehicle, resulting in a waste of resources.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, 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 creative work are within the scope of protection of the present invention.

[0023] The following is combined with Figure 1-6The specific implementation modes of the present invention are described in further detail.

[0024] In this embodiment, the present invention includes a winding box 1, a first support frame 2 and a second support frame 3 are fixed to the lower part of the winding box 1, a winding motor 4 is fixed in the winding box 1, a winding column 5 is fixed on the output shaft of the winding motor 4, a rolling shutter assembly is fixed on the winding column 5, the rolling shutter assembly is located between the first support frame 2 and the second support frame 3, limit blocks 6 are arranged at both ends of the rolling shutter assembly, the first support frame 2 and the second support frame 3 are arranged inside the limit assembly matching the limit blocks 6, a control box 7 is fixed on the second support frame 3, a bottom plate 8 is fixed to the bottom of the rolling shutter assembly, an infrared detector 9 and an infrared ranging sensor 10 are fixed on the bottom plate 8, and the infrared detector 9, the infrared ranging sensor 10, the winding motor 4 and the limit assembly are all electrically connected to the control box 7;

[0025] The control box 7 is electrically connected with Bluetooth communication, and can be connected to a mobile phone via Bluetooth. The mobile phone sends instructions to control the operation of the winding motor 4, thereby controlling the rotation of the winding column 5 to drive the rolling shutter assembly to be wound up, so as to open it. The infrared detector 9 can detect whether there is an object blocking the front of the bottom plate 8. The infrared detector 9 mainly measures the height of the vehicle blocking the front. The infrared distance sensor 10 is mainly used to detect the distance to the object. The infrared distance sensor 10 irradiates the bottom of the floor. When the rolling shutter assembly rises and opens, the infrared distance sensor 10 will turn on. When a vehicle passes under the rolling shutter assembly, the infrared distance sensor 10 will continuously measure the distance to the vehicle. The safety range of the infrared distance sensor 10 is set to ten centimeters through the control box 7. When the infrared distance sensor 10 detects that the distance to the object below is less than ten centimeters, it will transmit a signal to the control box 7, and the control box 7 is used to control the operation of the limit assembly to limit the descent of the rolling shutter assembly.

[0026] By measuring the height of the vehicle through the infrared detector 9, the winding motor 4 can drive the rolling curtain assembly to rise to a suitable height without fully opening the rolling curtain assembly, thereby reducing the operating time of the winding motor 4 and the rolling curtain assembly and extending their service life;

[0027] When the vehicle drives in front of the rolling shutter assembly, the control box 7 is connected to the mobile phone to control the winding motor 4 to run, and the control box 7 will control the infrared detector 9 to run, and the winding motor 4 controls the winding column 5 to rotate and drive the rolling shutter assembly to roll up, thereby driving the bottom plate 8 to rise, and the bottom plate 8 drives the infrared detector 9 and the infrared ranging sensor 10 to rise. At this time, the infrared detector 9 will continue to detect whether there is an object blocking the front. When the infrared detector 9 rises to a height higher than the vehicle height, it will continue to rise. The controller can be set in advance that after the infrared detector 9 detects no object blocking, the winding motor 4 will continue to drive the bottom plate 8 to rise to a height of fifteen centimeters, thereby ensuring that the vehicle has a safe passing height. When the rolling shutter assembly starts to roll up, the limit assembly will receive the control box 7 signal for conversion, so that the limit assembly runs and sets the limit. During the rising process of the rolling shutter assembly, the rolling shutter assembly is limited to fall, so as to avoid the failure of the winding motor 4 causing the rolling shutter assembly to fall and cause damage to the vehicle.

[0028] In this embodiment, the rolling shutter assembly is composed of a plurality of rolling shutter plates 11, a rolling shutter shaft 12 is fixed to the lower end of each rolling shutter plate 11, and every two adjacent rolling shutter plates 11 are hinged by the rolling shutter shaft 12, and two limit blocks 6 are respectively fixed to the two ends of the rolling shutter shaft 12 located at the lower end;

[0029] The bottom plate 8 is hinged to the lowest rolling shutter plate 11 through the lowest rolling shutter shaft 12, and the front side of each rolling shutter plate 11 is arranged in an arc shape.

[0030] In this embodiment, the first support frame 2 and the second support frame 3 are both provided with a mounting groove 13, and both ends of each roller blind shaft 12 are fixed with a limiting column 14, and each limiting column 14 is located in the mounting groove 13, and two limiting blocks 6 are respectively fixed to the sides of the limiting columns 14 located at both ends of the lowermost roller blind shaft 12, and the two limiting blocks 6 are both located in the mounting groove 13;

[0031] Both ends of the rolling shutter shaft 12 are fixedly connected to the limit columns 14 through two short cylinders. The width of the side of the mounting groove 13 close to the rolling shutter shaft 12 is smaller than the width of the rolling shutter plate 11 and larger than the width of the short cylinder, so that the rolling shutter plate 11 can rotate during the lifting process, but the rotation range is less than ten degrees.

[0032] In this embodiment, two clamping plates 15 are fixed to the rear ends of the two limit blocks 6, and the two clamping plates 15 located on the same limit block 6 are fixed symmetrically;

[0033] An opening is provided between the two card plates 15 and the limit block 6. The opening between the card plate 15 on the upper side and the limit block 6 faces upward, and the opening between the card plate 15 on the lower side and the limit block 6 faces downward. When the limit assembly adjusts the limit position of the rolling shutter assembly, it is achieved by cooperating with the card plate 15.

[0034] In this embodiment, two rubber damping pads 16 are fixed in the first support frame 2 and the second support frame 3 respectively, and each of the two rubber damping pads 16 is installed on the front and rear sides of the limiting column 14;

[0035] When the rolling shutter plate 11 and the rolling shutter shaft 12 are rising and falling, the limit column 14 will continuously collide with the first support frame 2 and the second support frame 3. By setting the rubber damping pad 16, the limit column 14 can collide with the rubber damping pad 16, thereby reducing noise generation and noise reduction. The distance between the two rubber damping pads 16 and the limit column 14 is smaller than the distance between the short cylinder and the wall of the mounting groove 13, thereby preventing the short cylinder from hitting the wall of the mounting groove 13.

[0036] In this embodiment, the limit assembly includes a limit motor 17 fixed in the second support frame 3, a disc 25 is fixed on the output shaft of the limit motor 17, a first matching plate 18 is rotatably connected to the disc 25, two first support bars 19 are fixed on the first matching plate 18, a plurality of limit bars 20 are rotatably connected between the two first support bars 19, the other end of each limit bar 20 is rotatably connected between two second support bars 21, the two second support bars 21 are fixed to the front side of the mounting plate 22, the mounting plate 22 is horizontally slidably arranged in the second support frame 3, a plurality of springs 23 are arranged in the second support frame 3, one end of each spring 23 is fixed on the second support frame 3, the other end of each spring 23 is fixed on the mounting plate 22, the limit motor 17 can drive the first matching plate 18 to rotate an angle, thereby adjusting the rotation angle of the limit bar 20;

[0037] The disc 25 is arranged concentrically with the output shaft of the limit motor 17, and the first matching plate 18 is rotatably connected to the side of the disc 25, and the rotation connection point is not concentric with the disc 25;

[0038] When the limit motor 17 is running, it drives the disc 25 to rotate, and the disc 25 drives the matching plate to move. Since the limit bar 20 on the first matching plate 18 rotates and connects the first support bar 19 and the second support bar 21 at the same time, the movement path of the first matching plate 18 is that the limit bar 20 rotates around the rotation axis between the second support bar 21. Therefore, by controlling the running direction of the limit motor 17, the rise and fall of the first matching plate 18 can be controlled. The movement path of the first matching plate 18 is an arc. When the first matching plate 18 rises, it drives the first support bar 19 to rise. The first support bar 19 drives the front end of the limit bar 20 to rise, and the limit bar 20 rotates around the rotation connection axis with the second support bar 21, so as to understand the inclination angle of the limit bar 20;

[0039] In a normal state, the limit bar 20 and the card plate 15 are located on the same vertical line after the angle is adjusted, and the limit bar 20 will be touched when moving upward or downward.

[0040] When the front end of the limit strip 20 faces upward and the rear end faces downward, the roller blind assembly can be limited to fall. The working principle is as follows:

[0041] When the winding motor 4 receives the control signal from the control box 7 and drives the rolling shutter assembly to rise, the limit motor 17 receives the signal and drives the first matching plate 18 to rise, driving the limit strip 20 to rotate, so that the front end of the limit strip 20 faces upward. At this time, the rolling shutter shaft 12 drives the limit column 14 and the limit block 6 to rise. When the card plate 15 on the limit block 6 moves upward, it will continuously support the limit strip 20, thereby pushing the limit strip 20 to move away from the limit block 6. The limit strip 20 drives the first support bar 19, the second support bar 21, the first matching plate 18 and the mounting plate 22 to move, thereby squeezing the spring 23, so that The limit block 6 continues to rise, and each time the card plate 15 does not contact the limit strip 20, the limit strip 20 will be pushed back by the spring 23. The width between each two limit strips 20 is greater than the height of the card plate 15, so that each time the card plate 15 separates from a limit strip 20, it takes a certain distance before it contacts the next limit strip 20 again. When the winding motor 4 fails or the winding assembly breaks, causing the winding assembly to descend, the limit block 6 and the card plate 15 will descend. When the card plate 15 descends, it will be inserted into the limit strip 20 located on the lower side, so that it is supported and limited by the limit strip 20, and the card plate 15 is restricted from continuing to descend.

[0042] Similarly, when the winding motor 4 drives the roller shutter assembly to rise, the limit motor 17 controls the limit bar 20 to rotate so that the front end of the limit bar 20 faces downward and does not limit the roller shutter assembly from descending. If the winding motor 4 fails or the winding assembly breaks, the infrared ranging sensor 10 descends with the base plate 8. When the infrared ranging sensor 10 detects that the distance between it and the object below is less than ten centimeters, it will transmit a signal to the control box 7, which controls the operation of the limit assembly through the control box 7, so that the front end of the limit bar 20 faces upward and limits the roller shutter assembly from descending.

[0043] In this embodiment, the plurality of limiting strips 20 are arranged at equal intervals.

[0044] In this embodiment, an arc plate 24 is fixed to the upper end of each two rubber damping pads 16 . The two arc plates 24 are symmetrically installed, and an opening is formed between the two arc plates 24 , so that the limit block 6 can enter between the two rubber damping pads 16 more easily.

[0045] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
