Description

Technical Field

[0001] This invention belongs to the field of garage door technology and relates to a garage door adjustment mechanism with intelligent position control function. Background Technology

[0002] A garage generally refers to a place where people park their cars. With social development and the improvement of people's economic level, the ownership rate of cars is getting higher and higher, and more and more families own private garages to park their cars. Due to the convenience of electric roller shutters, most existing garage doors are equipped with electric roller shutters. Roller shutters consist of multiple articulated door panels connected together, rotating up and down within fixed tracks around a central roller at the top. Roller shutters are commonly used in shops. Like walls, roller shutters serve as horizontal partitions. They consist of multiple parts, including curtain panels, base plates, guide rails, supports, rollers, housing, control box, roller door motor, limit switches, lintel, manual quick-release switch, push-button switch, and safety devices. They are generally installed in locations where it is inconvenient to use walls for partitioning.

[0003] However, existing garage doors are not intelligent in use. Every time the roller shutter door opens automatically, it opens completely to allow vehicles to enter and exit. It cannot adjust the opening height of the garage door according to the height of the vehicle, resulting in a waste of resources. Therefore, it is necessary to design a garage door adjustment mechanism with intelligent position control function to solve the above problems. Summary of the Invention

[0004] To address the aforementioned problems and overcome the shortcomings of existing technologies, this invention proposes a garage door adjustment mechanism with intelligent positioning control. The purpose of this invention is to: intelligently control the rising height of the roller shutter assembly without fully opening it, thereby reducing equipment operating time and extending its service life; add a limit component to restrict the unidirectional rising of the roller shutter assembly and prevent sudden falls during the rising process; and add a distance measurement function for objects below, which can detect when an object is too close and restrict the descent of the roller shutter assembly, thus increasing safety.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: The present invention includes a winding box, a first support frame and a second support frame are fixed to the lower part of the winding box, a winding motor is fixed inside the winding box, a winding column is fixed on the output shaft of the winding motor, a roller shutter assembly is fixed on the winding column, the roller shutter assembly is located between the first support frame and the second support frame, limit blocks are provided at both ends of the roller shutter assembly, limit components that cooperate with the limit blocks are provided inside the first support frame and the second support frame, a control box is fixed on the second support frame, a base plate is fixed to the bottom of the roller shutter assembly, an infrared detector and an infrared ranging sensor are fixed on the base plate, and the infrared detector, the infrared ranging sensor, the winding motor and the limit components are all electrically connected to the control box.

Each limiting post is located in the mounting groove, and two limiting blocks are respectively fixed to the sides of the limiting posts located at both ends of the lowest roller blind shaft. Both limiting blocks are located in the mounting groove.

[0008] Preferably, two locking plates are fixed to the rear ends of both limiting blocks, and the two locking plates located on the same limiting block are fixed symmetrically.

[0009] Preferably, two rubber damping pads are fixed in the first support frame and the second support frame respectively, and each pair of rubber damping pads is installed on the front and rear sides of the limiting post.

[0014] This invention, through the cooperation of a limiting component, a roller shutter assembly, a control box, and a limiting block, can restrict the descent of the roller shutter assembly when a vehicle passes underneath, preventing the roller shutter assembly from falling off and damaging the vehicle. Simultaneously, through the cooperation of an infrared detector and an infrared ranging sensor, it can intelligently control the roller shutter assembly to rise to an appropriate height when the vehicle enters the parking space, without fully raising the roller shutter assembly, saving power and reducing the travel distance of the roller shutter assembly, thus extending the service life of the winding motor and the roller shutter assembly. Furthermore, it can detect objects below during the descent of the roller shutter assembly, preventing damage to people or objects that might be present when the roller shutter assembly descends.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] The following is in conjunction with the appendix Figure 1-6The specific embodiments of the present invention will be described in further detail below.

[0024] In this embodiment, the present invention includes a winding box 1, a first support frame 2 and a second support frame 3 fixed at the lower part of the winding box 1, a winding motor 4 fixed inside the winding box 1, a winding column 5 fixed on the output shaft of the winding motor 4, a roller blind assembly fixed on the winding column 5, the roller blind assembly being located between the first support frame 2 and the second support frame 3, limit blocks 6 being provided at both ends of the roller blind assembly, limit components cooperating with the limit blocks 6 being provided inside the first support frame 2 and the second support frame 3, a control box 7 being fixed on the second support frame 3, a base plate 8 being fixed at the bottom of the roller blind assembly, an infrared detector 9 and an infrared ranging sensor 10 being fixed on the base plate 8, and the infrared detector 9, the infrared ranging sensor 10, the winding motor 4 and the limit components being electrically connected to the control box 7;

[0025] The control box 7 is electrically connected via Bluetooth, enabling it to connect to a mobile phone. Commands sent from the phone control the winding motor 4, which in turn controls the winding column 5 to rotate, causing the roller shutter assembly to wind up and open. The infrared detector 9 detects whether there are any obstructions in front of the floor 8. The infrared detector 9 primarily measures the height of any obstructing vehicle. The infrared distance sensor 10 is used to detect the distance to objects. The infrared distance sensor 10 illuminates the area below the floor. When the roller shutter assembly rises and opens, the infrared distance sensor 10 activates. As a vehicle passes under the roller shutter assembly, the infrared distance sensor 10 continuously measures the distance to the vehicle. The control box 7 sets the safety range of the infrared distance sensor 10 to ten centimeters. When the infrared distance sensor 10 detects an object less than ten centimeters away, it sends a signal to the control box 7, which then controls the limit switch to restrict the roller shutter assembly from descending.

[0026] By measuring the vehicle's height using infrared detector 9, the rewind motor 4 can drive the roller blind assembly to a suitable height without fully opening the roller blind assembly, thus reducing the operating time of the rewind motor 4 and the roller blind assembly and extending their service life.

[0027] When the vehicle approaches the roller blind assembly, the control box 7, connected via mobile phone, controls the winding motor 4 to operate. The control box 7 then controls the infrared detector 9 to operate. The winding motor 4 controls the winding column 5 to rotate, causing the roller blind assembly to roll up, which in turn raises the base plate 8. The base plate 8 then raises the infrared detector 9 and the infrared distance sensor 10. During this time, the infrared detector 9 continuously detects whether there are any obstructions in 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 so that if the infrared detector 9 does not detect any obstructions, the winding motor 4 will continue to raise the base plate 8 by 15 centimeters, thus ensuring that the vehicle has a safe height to pass through. When the roller blind assembly begins to roll up, the limit component receives a signal from the control box 7 and switches to operate, setting a limit. During the upward movement of the roller blind assembly, the descent of the roller blind assembly is restricted to prevent the roller blind assembly from falling due to the failure of the winding motor 4, which could damage the vehicle.

[0028] In this embodiment, the roller blind assembly consists of multiple roller blind panels 11. Each roller blind panel 11 has a roller blind shaft 12 fixed at its lower end. Every two adjacent roller blind panels 11 are hinged together by the roller blind shaft 12. Two limiting blocks 6 are respectively fixed at both ends of the roller blind shaft 12 located at the lowest end.

[0029] The base plate 8 is hinged to the bottom roller shutter panel 11 via the bottom roller shutter shaft 12, and the front side of each roller shutter panel 11 is arc-shaped.

[0030] In this embodiment, the first support frame 2 and the second support frame 3 are both provided with mounting grooves 13. Each roller blind shaft 12 is fixed at both ends with a limiting post 14. Each limiting post 14 is located in the mounting groove 13. Two limiting blocks 6 are respectively fixed to the sides of the limiting post 14 located at both ends of the lowest roller blind shaft 12. Both limiting blocks 6 are located in the mounting groove 13.

[0031] Both ends of the roller shutter shaft 12 are fixedly connected to the limiting post 14 by two short cylinders. The width of the mounting groove 13 on the side near the roller shutter shaft 12 is smaller than the width of the roller shutter panel 11 but larger than the width of the short cylinder, so that the roller shutter panel 11 can rotate during the lifting and lowering process, but the rotation range is less than ten degrees.

[0032] In this embodiment, two locking plates 15 are fixed at the rear ends of the two limiting blocks 6, and the two locking plates 15 located on the same limiting block 6 are fixed symmetrically.

[0033] An opening is provided between the two card plates 15 and the limiting block 6. The opening between the upper card plate 15 and the limiting block 6 faces upward, and the opening between the lower card plate 15 and the limiting block 6 faces downward. When the limiting component adjusts the limit of the roller shutter assembly's retraction, it is achieved by cooperating with the card plates 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 pair of rubber damping pads 16 is installed on the front and rear sides of the limiting post 14.

[0035] During the rising and falling process of the roller shutter panel 11 and roller shutter shaft 12, the limiting post 14 will continuously hit the first support frame 2 and the second support frame 3. By setting the rubber damping pad 16, the limiting post 14 can hit the rubber damping pad 16, thereby reducing noise generation and noise reduction. The distance between the two rubber damping pads 16 and the limiting post 14 is less than the distance between the short cylinder and the wall of the mounting groove 13, thus avoiding the short cylinder hitting the wall of the mounting groove 13.

[0036] In this embodiment, the limiting component includes a limiting motor 17 fixed within the second support frame 3. A disc 25 is fixed on the output shaft of the limiting motor 17. A first mating plate 18 is rotatably connected to the disc 25. Two first support bars 19 are fixed on the first mating plate 18. Multiple limiting bars 20 are rotatably connected between the two first support bars 19. The other end of each limiting bar 20 is rotatably connected between two second support bars 21. Both second support bars 21 are fixed to the front side of the mounting plate 22. The mounting plate 22 is horizontally slidably disposed within the second support frame 3. Multiple springs 23 are disposed within the second support frame 3. One end of each spring 23 is fixed to the second support frame 3, and the other end of each spring 23 is fixed to the mounting plate 22. The limiting motor 17 can drive the first mating plate 18 to rotate by an angle, thereby adjusting the rotation angle of the limiting bars 20.

[0037] The output shaft of the disc 25 and the limit motor 17 are concentrically arranged, and the first mating plate 18 is rotatably connected to the side of the disc 25, but the rotatable connection point is not concentric with the disc 25.

[0038] When the limit motor 17 runs, it drives the disc 25 to rotate, and the disc 25 drives the mating plate to move. Since the limit strip 20 on the first mating plate 18 is simultaneously connected to the first support strip 19 and the second support strip 21, the movement path of the first mating plate 18 is that the limit strip 20 rotates around the rotation axis between the limit strip 20 and the second support strip 21. Therefore, by controlling the rotation direction of the limit motor 17, the rise and fall of the first mating plate 18 can be controlled. The movement path of the first mating plate 18 is arc-shaped. When the first mating plate 18 rises, it drives the first support strip 19 to rise. The first support strip 19 drives the front end of the limit strip 20 to rise. The limit strip 20 rotates around the rotation connection axis with the second support strip 21, thereby determining the tilt angle of the limit strip 20.

[0039] Under normal conditions, the adjustable limit bar 20 and the locking plate 15 are on the same vertical line after the angle is adjusted. Moving it upwards or downwards will cause it to contact the limit bar 20.

[0040] When the front end of the limiting strip 20 faces upward and the rear end faces downward, it can restrict the descent of the roller blind assembly. The working principle is as follows:

[0041] When the winding motor 4 receives a control signal from the control box 7 and drives the roller blind assembly to rise, the limit motor 17 receives a signal and drives the first mating plate 18 to rise, causing the limit bar 20 to rotate, thus making the front end of the limit bar 20 face upward. At this time, the roller blind shaft 12 drives the limit post 14 and the limit block 6 to rise. When the locking plate 15 on the limit block 6 moves upward, it will continuously press against the limit bar 20, thereby pushing the limit bar 20 to move away from the limit block 6. The limit bar 20 drives the first support bar 19, the second support bar 21, the first mating plate 18, and the mounting plate 22 to move, thereby compressing the spring 23, making... As the limit block 6 continues to rise, each time the clamping plate 15 does not contact the limit strip 20, the limit strip 20 will be pushed back to its original position by the spring 23. The width between each pair of limit strips 20 is greater than the height of the clamping plate 15, so that after the clamping plate 15 separates from one limit strip 20, it needs to travel a certain distance before it contacts the next limit strip 20 again. When the winding motor 4 malfunctions or the winding assembly breaks, causing the winding assembly to descend, the limit block 6 and the clamping plate 15 will descend. When the clamping plate 15 descends, it will insert into the limit strip 20 located on the lower side, thereby being supported and limited by the limit strip 20, restricting the clamping plate 15 from continuing to descend.

[0042] Similarly, when the winding motor 4 drives the roller blind 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, thus not restricting the descent of the roller blind assembly. If the winding motor 4 malfunctions or the winding assembly breaks, the infrared distance sensor 10 descends with the base plate 8. 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, which will then control the operation of the limit assembly, so that the front end of the limit bar 20 faces upward, thus restricting the descent of the roller blind assembly.

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

[0044] In this embodiment, an arc-shaped plate 24 is fixed to the upper end of each pair of rubber damping pads 16. The two arc-shaped plates 24 are installed symmetrically, and an opening is formed between the two arc-shaped plates 24, so that the limiting 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 foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
