When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.
[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0026] Example 1: See attached Figure 1-Figure 4 , an isolated permanent magnet infrared laser Hall button, comprising a head shell 1, a button head 2, a neodymium strong magnetic block 3, a crank assembly 4, a reset assembly 5, a fixing nut 6 and a rubber ring 7, a cavity 11 is provided in the head shell 1, the button head 2 is movably arranged in the cavity 11, a groove with an open end is provided on the button head 2, the side wall of the groove is covered with ferrite shielding glue, the neodymium strong magnetic block 3 is fixed in the groove, and by covering the ferrite shielding glue on the side wall of the groove, the neodymium strong magnetic block 3 can only emit a magnetic field in the opening direction of the groove; the crank assembly 4 is arranged at the bottom of the cavity 11 and is located below the neodymium strong magnetic block 3, a nano-cesium bronze coating is plated on the surface of the crank assembly 4, a penetrating installation cavity is provided on the button head 2 in the horizontal direction, the reset assembly 5 is arranged in the installation cavity, and the two ends of the reset assembly 5 are respectively extended out of the installation cavity, and are limited by the inner wall of the head shell 1, and one end of the button head 2 is in movably contact with the crank assembly 4. The crank assembly 4 is closed and opened by squeezing and releasing the crank assembly 4 through the button head 2. The side wall of one end of the head shell 1 away from the crank assembly 4 protrudes outward to form a support portion, and a mounting thread is provided on the outer wall of the head shell 1. The fixing nut 6 is threadedly sleeved on the outer side of the mounting thread. The outer wall of the fixing nut 6 is located inside the extension line of the outer wall of the support portion. The rubber ring 7 is sleeved on the outer side of the head shell 1, and the rubber ring 7 is located between the support portion and the fixing nut 6.
[0027] The button body in this solution needs to be used together with the receiving control device, in which a magnetic Hall sensor 82 and an infrared laser head 83 are provided. When installing the button body, first install the reset component 5 into the installation cavity on the button head 2, and then embed the button head 2 into the head shell 1; then install the head shell 1 into the required installation position on the control panel, put the rubber ring 7 on the head shell 1, and finally fix it with the fixing nut 6, wherein the rubber ring 7 can be made of nitrile. The signal transmitting and receiving port of the receiving control device used in conjunction corresponds to the position of the neodymium strong magnetic block 3.
[0028] When the button head 2 is not pressed, the crank assembly 4 is in an open state. Figure 1 As shown, the infrared signal emitted by the receiving control device is absorbed by the crank assembly 4, and the internal signal processing system makes a judgment and outputs the result signal; when the button head 2 is pressed, as shown in FIG. Figure 3 As shown, the magnetic Hall sensor 82 is affected by the magnetic field of the neodymium strong magnetic block 3 and outputs a signal to the internal signal processing system. At the same time, since the crank assembly 4 is in a closed state, there is no obstruction of the crank assembly 4. The infrared signal emitted by the receiving control device is emitted to the surface of the neodymium strong magnetic block 3 and then returned to the internal signal processing system. The internal signal processing system makes a judgment after receiving the above signal and outputs the result signal. After releasing the button head 2, under the action of the reset assembly 5, the button head 2 returns to the initial state, and the crank assembly 4 returns to the open state.
[0029] The invention has high reliability, high protection level and low cost, and can be applied to high protection level environments such as waterproof, dustproof, corrosion-resistant, high temperature or low temperature environment.
[0030] like Figure 2 As shown, the crank assembly 4 includes a crank body 41 and a crank return spring 42. The surface of the crank body 41 is plated with a nano-cesium bronze coating. The crank body 41 is rotatably set at the bottom of the cavity 11 through a fixing pin and is supported by the shell wall of the head shell 1. One end of the crank return spring 42 is fixed on the crank body 41, and the other end is fixed on the bottom of the cavity 11. One end of the button head 2 is in active contact with the crank body 41.
[0031] When the button head 2 is not pressed, the crank assembly 4 is in an open state. Figure 1 As shown, the infrared signal emitted by the receiving control device is absorbed by the crank body 41, and the internal signal processing system makes a judgment and outputs the result signal; when the button head 2 is pressed, as shown in FIG. Figure 3As shown, the end of the button head 2 presses against the crank body 41, and the crank body 41 rotates with the fixed pin as the axis, and a free end of the crank body 4 contacts the button head 2, closing the crank body 4. The magnetic Hall sensor 82 is affected by the magnetic field of the neodymium strong magnetic block 3 and outputs a signal to the internal signal processing system. At the same time, since the crank assembly 4 is in a closed state and there is no obstruction from the crank assembly 4, the infrared signal emitted by the receiving control device is emitted to the surface of the neodymium strong magnetic block 3 and then returned to the internal signal processing system. The internal signal processing system makes a judgment after receiving the above signal and outputs the result signal.
[0032] Preferably, the crank body 41 is Y-shaped, and one end of the button head 2 is in active contact with a short side of the crank body 41. When the button head 2 is pressed, one end of the button head 2 abuts against a short side of the crank body 41 and presses downward until the long side end of the crank body 41 contacts the button head 2, closing the crank body 4.
[0033] like Figure 1 As shown, the inner wall of the head shell 1 protrudes toward one side of the cavity 11 to form a first limiting portion, and the bottom end of the button head 2 protrudes outward to form a first limiting protrusion. The first limiting protrusion is located below the first limiting portion and is limited by the first limiting portion. The two ends of the reset component 5 are limited by the end of the first limiting portion away from the first limiting protrusion. By setting the first limiting portion and the first limiting protrusion, the movable distance of the button head 2 is limited; when the button head 2 is pressed, the first limiting protrusion moves in the direction away from the reset component 5, and the reset component 5 is compressed. After releasing the button head 2, the reset component 5 returns to the initial state, and the first limiting protrusion returns to the position abutting against the bottom of the first limiting portion.
[0034] like Figure 1 As shown, one end of the button head 2 away from the crank assembly 4 protrudes outward to form a second limiting protrusion, and the inner wall of the head shell 1 protrudes toward the side of the cavity 11 to form a second limiting portion, which is located on the side of the first limiting portion away from the crank assembly 4.
[0035] like Figure 1 As shown, the reset assembly 5 includes at least one elastic reset member. When the number of the elastic reset members is greater than 1, two or more elastic reset members are stacked in the vertical direction.
[0036] Embodiment 2: A receiving control device is used in conjunction with an isolated permanent magnet infrared laser Hall button, comprising a housing 8, a lens 81, a magnetic Hall sensor 82, an infrared laser head 83, an infrared processing unit 84 and a logic judgment unit 85. A signal transmitting and receiving port is provided at one end of the housing 8, the lens 81 is arranged at the signal transmitting and receiving port of the housing 8, the magnetic Hall sensor 82, the infrared laser head 83, the infrared processing unit 84 and the logic judgment unit 85 are respectively arranged in the housing 8, and the housing 8 is also filled with hybrid carbon nanofillers to isolate the electromagnetic field through the hybrid carbon nanofillers.
[0037] When the button head 2 is not pressed, the crank assembly 4 is in an open state, the infrared signal emitted by the infrared laser head 83 is absorbed by the crank assembly 4 and fed back to the logic judgment unit 85 through the infrared processing unit 84, and the logic judgment unit 85 makes a judgment and outputs the result signal; when the button head 2 is pressed, the crank body 4 is closed, and the magnetic Hall sensor 82 is affected by the magnetic field of the neodymium strong magnet block 3, and outputs a signal to the logic judgment unit 85. At the same time, since the crank assembly 4 is in a closed state and there is no obstruction from the crank assembly 4, the infrared signal emitted by the infrared laser head 83 is transmitted to the surface of the neodymium strong magnet block 3 and then returned to the infrared processing unit 84. The infrared processing unit 84 makes a judgment after receiving the above signal and outputs the result signal.
[0038] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
