[0002] The sensor of the automatic door is an important part of the door control system. It is used to detect the approach of people or objects and trigger the opening and closing of the door. The infrared sensor is one of the most common types of sensors in automatic doors. It mainly uses human body sensing radiation to detect the opening and closing status of the door.

[0003] Infrared sensors can detect infrared radiation emitted by the human body and judge whether the door needs to be opened or closed. When a person or object enters the detection range of the sensor, the sensor will emit a sensor and wait for its reflection. These sensors will be reflected when encountering a person or object, and the reflected sensors will be received by the receiving tube inside the sensor.

[0004] When detecting on both sides of the automatic door, a large amount of dust and water vapor will adhere to the outer surface of the sensor, thereby affecting the detection sensitivity of the sensor and causing the sensor to respond insensitively. Utility Model Content

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Reference Figure 1-Figure 5 A multifunctional sensor for an automatic door comprises: a housing 1, two ends of the housing 1 are provided with mounting openings, a sensor assembly 2 is arranged inside the mounting opening, and two sensor assemblies 2 are symmetrically arranged and sense in two directions;

[0029] The bottom of the housing 1 is provided with a sliding component 3, and the bottom of the sliding component 3 is provided with a cleaning component 4, and the cleaning component 4 is used to clean the outside of the sensor component 2;

[0030] The cleaning assembly 4 includes a connecting rod 41, a bent rod 42 and a cleaning sheet 43. The middle portion of the connecting rod 41 is fixedly connected to the sliding assembly 3. The two bent rods 42 are symmetrically fixedly connected to the two ends of the connecting rod 41. The two cleaning sheets 43 are fixedly connected to the inner side of the bent rod 42 and are in contact with the sensor assembly 2.

[0031] In the utility model, when water mist or dust adheres to the sensor component 2, the sliding component 3 drives the cleaning component 4 to move, and the connecting rod 41 drives the bent rods 42 and the cleaning sheets 43 on both sides to slide, and the moving cleaning sheets 43 clean the sensor components 2 on both sides in time, thereby ensuring the sensitivity of the sensor component 2.

[0032] The preferred technical solution in this embodiment is that the sliding component 3 includes a driving module 31 and a driving block 32. The driving module 31 is fixedly installed inside the shell 1 and has a slide groove on the bottom. A control system is arranged inside the driving module 31 for controlling the driving block 32 to slide inside the slide groove. The existing slide rail component can be adopted. The bottom surface of the shell 1 has a strip opening. The upper end of the driving block 32 passes through the strip opening and is slidably arranged inside the slide groove. The bottom of the connecting rod 41 is fixedly connected to the bottom end of the driving block 32. In the process of driving the cleaning component 4 to slide, the driving module 31 controls the driving block 32 to slide inside the slide groove, thereby driving the entire connecting rod 41 to slide at the bottom of the shell 1.

[0033] Reference Figure 2-Figure 3 The sensor assembly 2 includes a sensor terminal 21 and a controller 22. The sensor terminal 21 is in a strip shape and is installed inside the installation port. The controller 22 is fixedly installed inside the housing 1 and is connected to the sensor terminal 21 for controlling the sensor terminal 21. The controller 22 controls the sensor transmission and reception of the sensor terminal 21, processes the received signal, and then opens and closes the automatic door.

[0034] The bent rod 42 is an arc-shaped rod having the same shape as the sensing end 21 . The bent rod 42 is made of an elastic material. In order to ensure the cleaning effect on the sensing end 21 , the bent rod 42 contacts the sensing end 21 and ensures the cleaning effect.

[0035] A dust outlet 5 is provided in the middle of the bent rod 42, and the two sides of the dust outlet 5 are inclined toward the middle for exporting dust. When the cleaning sheet 43 scrapes and cleans the sensor end 21, the dust can be exported from the dust outlet 5 to avoid dust accumulation on the cleaning sheet 43.

[0036] Reference Figure 4 Two sealing components 6 are symmetrically arranged at the bottom of the housing 1. The two sealing components 6 are arranged on both sides of the connecting rod 41 for sealing the strip-shaped opening.

[0037] The sealing assembly 6 includes a side frame 61, an elastic strip 62 and a folding strip 63. The side frame 61 is fixedly connected to the side of the bottom surface of the shell 1, the elastic strip 62 is fixedly connected to the folding strip 63, one end of the elastic strip 62 is fixedly connected to the side frame 61, and one end of the folding strip 63 is fixedly connected to the side of the connecting rod 41. In order to prevent a large amount of water vapor from entering the interior of the shell 1, the elastic strip 62 and the folding strip 63 are provided to ensure that the strip opening position is sealed during the movement of the driving block 32, thereby ensuring the normal movement of the driving block 32.

[0038] Reference Figure 1-Figure 3 A connecting groove is provided in the middle of the shell 1, and a connecting component 7 is provided inside the connecting groove. The connecting component 7 is used to fix the position of the shell 1.

[0039] The connection assembly 7 includes a fixing frame 71 and a plurality of connecting bolts 72. The fixing frame 71 is in an I-shape. The plurality of connecting bolts 72 are used to connect the four sides of the fixing frame 71. The connecting bolts 72 are used to connect to the external wall, so as to fix the position of the sensor.

[0040] The two sides of the shell 1 are fixedly connected with sensing strips 8, which are an infrared sensor that monitors the dust and water mist on the surface of the terminal through infrared rays. The sensing strips 8 are used to detect the outside of the sensing terminal 21. The sensing strips 8 can sense the water mist and dust on the sensing terminal 21, thereby controlling the driving module 31 and cleaning the sensing terminal 21 in time.

[0041] It should be noted that when the driving module 31 detects that the external dust and water mist are within the preset range, it controls the driving block 32 to move. The control algorithm used is a conditional control algorithm, which is a common and mature algorithm in the prior art. Therefore, the multifunctional sensor for automatic doors provided by the utility model does not involve improvements to the algorithm.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
