Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of obstruction-detection and stopping devices, specifically relating to an obstruction-detection and stopping device for electric door opening and closing. Background Technology
[0002] Electric rolling doors, also known as electric roller shutters, are roller shutter doors that use an electric drive device and are controlled to open and close via remote control or buttons. They are widely used in garages, shops, warehouses, factories, and other places to improve safety and ease of use.
[0003] However, in actual use, those skilled in the art have found that when existing electric doors encounter resistance or are pressed against objects during the closing or opening process, the door opener will continue to open or close, which will damage the door and other items. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an electric door opening and closing device that stops when it encounters an obstacle, which has the advantage of automatically stopping the door when it encounters an obstacle during the opening and closing process.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an electric door opening and closing obstruction stopping device, including an electric door bottom beam, a track, a detector bracket and a door opener, and further including: a color mark strip set on the track, the color mark strip being composed of alternating black blocks and white or yellow blocks;
[0006] A color mark detector fixed to a detector bracket is used to detect changes in the color blocks of a color mark band;
[0007] The processor, connected to the color mark detector, is used to control the operating status of the door opener based on the detection signal.
[0008] Preferably, the color mark detector outputs alternating detection signals when the door is operating normally, and outputs a continuous detection signal when the door stops due to an obstruction.
[0009] Preferably, the detector bracket has a first screw and a second screw inserted inside, and both the first screw and the second screw are threaded into the inside of the bottom beam. When the processor receives a continuous detection signal, it controls the door opener to stop running or run in reverse.
[0010] Preferably, the color blocks of the color mark band are arranged in an evenly spaced pattern of alternating black and white or alternating black and yellow.
[0011] Preferably, the color mark detector is a photoelectric sensor, and its detection end maintains a preset distance from the color mark strip.
[0012] Preferably, the color mark detector continuously detects the color block changes of the color mark strip as the bottom beam of the electric door moves up and down along the track.
[0013] Preferably, it also includes an electric door controller connected to the processor for sending door opening and closing commands to the door opener.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. When the electric gate encounters an obstacle during the opening and closing process, the gate operator will automatically stop operating or stop and reverse, thus effectively protecting the gate operator, the electric gate body, and the obstacle, preventing property damage, and reducing the maintenance rate of the electric gate and the gate operator.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-2 This utility model provides a technical solution: an electric door opening and closing obstruction stop device, including an electric door bottom beam 1, a track 2, a detector bracket 3 and a door opener 8, and also includes: a color mark strip 5 set on the track 2, which is composed of alternating black blocks and white or yellow blocks;
[0021] The color mark detector 4, fixed on the detector bracket 3, is used to detect changes in the color blocks of the color mark band 5;
[0022] The processor 10, connected to the color mark detector 4, is used to control the operating status of the door opener 8 based on the detection signal.
[0023] Specifically, the color mark detector 4 outputs alternating detection signals when the door is running normally, and outputs a continuous detection signal when the door stops due to an obstruction.
[0024] Specifically, the detector bracket 3 has a first screw 6 and a second screw 7 inserted inside, and both the first screw 6 and the second screw 7 are threaded into the bottom beam 1. When the processor 10 receives a continuous detection signal, it controls the door opener 8 to stop running or run in reverse.
[0025] Specifically, the color blocks of color 5 are arranged in an evenly spaced pattern of alternating black and white or alternating black and yellow.
[0026] Specifically, the color mark detector 4 is a photoelectric sensor, and its detection end maintains a preset distance from the color mark strip 5.
[0027] Specifically, the color mark detector 4 continuously detects the color block changes of the color mark strip 5 as the electric door bottom beam 1 moves up and down along the track 2.
[0028] Specifically, it also includes an electric door controller 9 connected to the processor 10, used to send door opening and closing commands to the door opener 8.
[0029] The working principle and usage process of this utility model: The color mark detector 4 moves up and down with the bottom beam 1 as the door opens and closes. While moving up and down, it also detects the color mark strip 5. When a black color block is detected, the color mark detector outputs a B signal. When a white color block (yellow color block) is detected, it outputs an A signal.
[0030] If the electric gate encounters an obstacle while opening or closing, causing the gate to stop, the color mark detector 4 will also stop. At this time, the color mark detector 4 will either stop on the black block or the white block (yellow block), and the color mark detector 4 will send a continuous signal A or a continuous signal B to the processor 10. The processor 10 will receive the continuous signal A or continuous signal B. As long as the signal received by the processor 10 is the continuous signal A or continuous signal B, it will issue a command to stop or reverse the gate opener 8. When the gate opener 8 receives the command to stop or reverse, the gate opener 10 will stop running or stop and then reverse, thus stopping the gate or stopping and then reversing. This avoids damage to the gate, the gate opener, and the obstacle caused by the gate encountering an obstacle while the gate is no longer moving.
[0031] When the electric door is operating normally without any obstacles, the color mark detector 4 moves up and down with the bottom beam 1 as the door opens and closes. The color mark detector 4 detects the black and white (yellow) color blocks on the black and white or black and yellow color mark strips 5 pasted on the track 2, thus stably outputting a BABABA loop signal to the processor 10. As long as the processor 10 receives the BABABA loop signal, it will not emit any signal, so the door can open and close normally.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
