Description

Technical Field

[0001] The utility model relates to the technical field of elevator outer call buttons, and specifically relates to an elevator outer call button. Background Art

[0002] Existing capacitive touch buttons are vulnerable to external electromagnetic interference and are prone to accidental touch during the startup of the elevator power frequency converter and the elevator operation stage. Moreover, infrared buttons are susceptible to external moisture, light, and human skin color. Especially in a foggy environment, it is easy to have problems such as insensitive touch and inability to trigger.

[0003] Chinese Patent Publication No. CN219058222U discloses an in - concave contactless elevator button, which is provided with a button housing with a groove, an infrared sensing module, a control module for controlling the change of the indicator light and the elevator call instruction. Users only need to extend their fingers into the groove of the target floor without touching the touch button. The infrared sensing module detects the extension of the limb and then transmits the signal to the control module, which then drives the elevator to run to the target floor. Not only is the user operation simple, but it also avoids contacting the elevator button, thus avoiding the risk of being infected by viruses on the button.

[0004] However, in actual use of the above structure, the infrared sensor detects whether a passenger presses the button by emitting infrared light and receiving its reflected signal. However, in a fog - filled or dust - covered situation, the infrared light will be scattered and absorbed during propagation, resulting in a significant weakening or even complete disappearance of the reflected signal. In this way, the sensor may not be able to accurately identify the button - pressing action of the passenger, causing the button to have no response or false response, which brings inconvenience to the passengers. Summary of the Utility Model

[0005] Aiming at the above problems, an elevator outer call button is provided, which solves the problem that fog or dust affects the normal use of the infrared sensor through an outer laser button, a light - transmissive protection plate, and a connection limiting mechanism.

Detailed Embodiment

[0026] In order to further understand the features, technical means and the specific purposes and functions achieved by the present utility model, the following further describes the present utility model in detail with reference to the drawings and specific embodiments.

[0027] SeeFigures 1-3 As shown in the figure, an elevator external call button includes an external call box 1, a controller 2 disposed on the external call box 1, an infrared laser button 3 disposed on the controller 2 for detecting the distance of an object, and a protection mechanism 4 rotatably disposed on the external call box 1 for protecting the infrared laser button 3. The protection mechanism 4 includes a light-transmitting protection plate 41 and a movable cleaning frame 42 slidably disposed in the light-transmitting protection plate 41 in a horizontal linear direction and for cleaning the inner wall of the light-transmitting protection plate 41. The elevator external call button further includes a connection limiting mechanism 5 for converting the tilting movement of the light-transmitting protection plate 41 into the horizontal linear sliding of the movable cleaning frame 42. The infrared laser button 3 is preferably a laser sensor chip VI5300 of high-precision packaging level. The infrared laser button 3 directly communicates with the controller 2 through I2C. The infrared laser button 3 has a built-in sensor 31, and the sensor 31 has a built-in adaptive algorithm, which can perform adaptive calibration, such as stains or pollutants, etc. There is no safety risk in the application of elevator buttons, and it can prevent the elevator from being accidentally opened due to detected stain occlusion, and can reduce the risk of contact infection, contact mis-touch and the problem of being susceptible to environmental interference.

[0028] The light-transmitting protection plate 41 can effectively protect the infrared laser sensor 31 disposed on the controller 2, and can reduce the entry of fog and dust. When it is necessary to check the infrared laser button 3 disposed on the controller 2, first pull the light-transmitting protection plate 41, and then the light-transmitting protection plate 41 can swing at an inclined angle until the light-transmitting protection plate 41 loses the shielding protection of the infrared laser button 3. During the tilting movement of the light-transmitting protection plate 41, the movable cleaning frame 42 can be driven by the connection limiting mechanism 5 to slide in the inner wall of the light-transmitting protection plate 41 in a horizontal linear direction. During the sliding of the movable cleaning frame 42, the inner wall of the light-transmitting protection plate 41 can be cleaned, which can prevent the inner wall of the light-transmitting protection plate 41 from having water droplets formed by atomization and temperature difference, thus affecting the normal use of the infrared laser button 3 and the sensor 31, ensuring that the infrared laser button 3 and the built-in sensor 31 can work normally, and there is no need for manual cleaning of its interior.

[0029] See Figures 3-5 As shown in the figure, the connection limiting mechanism 5 includes a mounting block 51, a limiting rod 52 and a return spring 53; the mounting block 51 is disposed on the light-transmitting protection plate 41 and there are several of them; there is a pair of limiting rods 52 disposed on the mounting block 51, and the movable cleaning frame 42 is in clearance fit with the limiting rod 52; the return spring 53 is disposed on the mounting block 51, and the two ends of the return spring 53 are respectively fixed to the mounting block 51 and the end of the movable cleaning frame 42.

[0030] When the light-transmitting protection plate 41 makes an inclined swing to open, during this process, it can cause the movable cleaning frame 42 to slide in the horizontal linear direction along the limiting rod 52 with clearance fit, and during this process, the return spring 53 is compressed. When moving, it can wipe and clean the water droplets and dust on the inner wall of the light-transmitting protection plate 41 in a timely manner, avoiding affecting the normal operation of the infrared laser button 3 and the sensor 31.

[0031] See Figures 3-5 As shown, the connection limiting mechanism 5 further includes a connection block 54 and an elastic traction member 55; the connection block 54 is arranged on the controller 2 and is located on both sides of the infrared laser button 3; the elastic traction member 55 is arranged on the connection block 54 and is connected to the movable cleaning frame 42.

[0032] During the process of the light-transmitting protection plate 41 tilting and opening, it can cause the elastic traction member 55 to be pulled. Since the position of the elastic traction member 55 is fixed, when the light-transmitting protection plate 41 opens, it can cause the movable cleaning frame 42 to be pulled by the elastic traction member 55, and the return spring 53 is compressed. Furthermore, the elastic traction member 55 can pull the movable cleaning frame 42 to slide in the horizontal linear direction, achieving the pulling of the movable cleaning frame 42. When the light-transmitting protection plate 41 closes, the return spring 53 releases and pushes the movable cleaning frame 42 to slide back to its original position.

[0033] See Figure 4 As shown, the connection limiting mechanism 5 further includes a ventilation opening 56 and a discharge chamber 57; the ventilation opening 56 is opened below the light-transmitting protection plate 41; the discharge chamber 57 is opened on the light-transmitting protection plate 41 and corresponds to the position of the movable cleaning frame 42.

[0034] After the movable cleaning frame 42 returns to its original position, the cleaned water droplets or dust can be discharged through the position of the discharge chamber 57 opened on the light-transmitting protection plate 41. The discharge chamber 57 is used for the cleaned dust to fall. The setting of the ventilation opening 56 is used to prevent heat accumulation when the infrared laser button 3 and the sensor 31 are in use, and is conducive to the discharge of humid air.

[0035] See Figures 2-6 As shown, the elevator external call button further includes an outer wall cleaning mechanism 6 arranged on the outer call box 1 for cleaning the outer wall of the light-transmitting protection plate 41; the outer wall cleaning mechanism 6 includes a fixed rod 61, a connecting L-shaped rod 62, and a cleaning brush roller 63; the fixed rod 61 is arranged on the outer call box 1 and there are a pair of them; the connecting L-shaped rod 62 is arranged on the fixed rod 61 and is coaxially fixed with the fixed rod 61; the cleaning brush roller 63 is rotatably arranged on the connecting L-shaped rod 62, and the cleaning brush roller 63 is used to contact and wipe the outer wall of the light-transmitting protection plate 41.

[0036] When the light-transmitting protection plate 41 is tilted and opened, during this process, the cleaning brush roller 63 can slide vertically along the connecting L-shaped rod 62, which can cause the cleaning brush roller 63 to wipe the outer wall of the light-transmitting protection plate 41 during the opening process, so as to achieve wiping and cleaning the outer wall of the light-transmitting protection plate 41 while the light-transmitting protection plate 41 is being opened.

[0037] See Figure 6 As shown, the outer wall cleaning mechanism 6 further includes a displacement sliding groove 64 and a rotating rod 65; the displacement sliding groove 64 is opened on the connecting L-shaped rod 62; the rotating rod 65 is arranged in the displacement sliding groove 64, and the rotating rod 65 is coaxially fixed with the cleaning brush roller 63.

[0038] During the opening process of the light-transmitting protection plate 41, it can cause the cleaning brush roller 63 and the rotating rod 65 to slide vertically along the displacement sliding groove 64 opened on the connecting L-shaped rod 62, so that the rotating rod 65 and the cleaning brush roller 63 can always be in contact with the outer wall of the light-transmitting protection plate 41 without affecting the normal use of the infrared laser button 3 and the sensor 31.

[0039] The above embodiments only represent one or several implementation manners of the present invention, and the description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
