Abstract

The present invention provides a touch-control push button device encircled with light emitting diodes. The touch-control push button device includes a push button substrate, a frame and at least one light emitting diode light ribbon. One side surface of the push button substrate is provided with at least one color light sensing element. In addition, the frame is a hollowed frame body for being assembled to the periphery of the push button substrate, so that the color light sensing element can be completely located in an accommodation space surrounded by the frame. Furthermore, each light emitting diode light ribbon is assembled to an inner side surface of the frame corresponding to the accommodation space, and the light emitting diodes thereof emit light beam of specific color for being received by the color light sensing element. As a result, when one of the color light sensing elements is completely shielded by a foreign object, such as a finger, the light beam of specific color cannot be received and thus a pressing signal is transmitted to a control unit for executing the corresponding control procedure. Accordingly, the present invention is able to provide users with a novel touch-control push button device.

Description

Touch button device with light emitting diode

The present invention relates to a button device, and more particularly to a light-emitting diode disposed on the button device, and capable of continuously detecting color light emitted by the light-emitting diodes by using a color light sensing component, and is After the finger shields one of the color light sensing components, the button device can execute a corresponding program, so that the button device can realize the button effect of the flat touch without using the liquid crystal touch panel.

According to the advancement of the technology industry, many novel products have been successfully developed and replaced, and replaced traditional products. For example, the security system currently used on the portal usually installs a button device near the door. When the user wants to enter and exit the door, the preset key combination (such as a password) must be pressed on the button device to open the control object (such as the iron door) installed at the door.

As shown in FIG. 1 , the key device 1 includes a keyboard body 10 , a key cap 11 , a rubber sleeve 13 , and a plurality of limiting components 15 . The keyboard body 10 is recessed with a plurality of key bases 100 (only one is shown in FIG. 1), one end of the rubber sleeve 13 is fixed in the key base 100, and the other end is connected with the key cap 11 In addition, the limiting members 15 are a rod body and are interlacedly inserted between the key cap 11 and the key base 100 so that when the user presses the key cap 11, the rubber sleeve 13 will be deformed by the force, and when the user no longer presses the keycap 11, the rubber sleeve 13 itself generates a restoring force, so that the keycap 11 can be restored to the original position, and by the The arrangement of the limiting member 15 can ensure that the key cap 11 is accurately displaced in the direction of the key base 100 during the displacement without deviating from the position of the key base 100. However, the aforementioned keyboard having a mechanical button The device 1 still has many disadvantages after long-term use. First, the limiting elements 15 are subjected to long-term The action effect is easily damaged by the friction, causing dents or cracks on the surface of the limiting member 15, except that the movement trajectory of the keycap 11 is affected, and the keycap 11 cannot be smoothly moved, even in the When the user presses the button on the keyboard device 1 vigorously or quickly, the position limiting member 15 is easily broken. Moreover, the rubber sleeve 13 may also be elastically aged after being used for a long time. It is difficult to push the keycap 11 back to the original position. Therefore, when the rubber sleeve 13 and the limiting members 15 have problems, the key cap 11 is easily swayed or stuck during the user's pressing. The bad effect is that the user cannot enter the password smoothly.

As mentioned above, due to the shortcomings of the mechanical buttons, some operators have failed to operate the security system. Instead, the LCD touch panel is used as the button area of the button device, that is, the operator will plan multiple areas on the LCD touch panel. Block, and each block represents a certain button function (such as: 1, 2, 3, +, -), so that the user can input a preset password through the liquid crystal touch panel to smoothly open Controlling the object, however, although the LCD touch panel is extremely convenient in use, its cost is quite expensive, which causes the production cost of the manufacturer to remain high, and when one of the blocks of the liquid crystal touch panel is damaged, the user That is, the entire LCD touch panel must be replaced, resulting in a significant increase in the maintenance cost of the user. The above reasons also cause the user to use the button device with the liquid crystal touch panel less, which reduces the market competitiveness of the operator.

In summary, the conventional button device still has many shortcomings in use, which causes troubles for the operator and the user. Therefore, how to design a brand-new button device to effectively solve the above problem becomes the current button device manufacturer. Thinking about the major issues.

In view of the current button device, it is impossible to balance the long service life, low cost, low maintenance cost, etc. Therefore, after long-term research and experiment, the inventor finally developed and designed a ring of the present invention with a light-emitting diode. The control button device is intended to provide the user with a brand-new structure of the button device by the advent of the present invention, thereby improving the market competitiveness of the operator.

An object of the present invention is to provide a touch button device with a light-emitting diode, the touch button device comprising a control unit, a button substrate, a frame and at least one light-emitting diode light bar, the button One side of the substrate is provided with at least one color light sensing component, each of the color light sensing components being electrically connected to the control unit, and capable of transmitting a pressing signal (eg, high after receiving a specific color of light). a potential is given to the control unit, and the frame is a hollow frame, and an accommodating space is formed in the inner frame, and the frame is assembled to the periphery of the button substrate corresponding to one side of the accommodating space, so that each The color light sensing element and the lens thereon can be completely positioned in the accommodating space, and the other edge of the frame corresponding to the accommodating space extends away from the button substrate, and further, each of the illuminating lights The pole light strip is assembled to the inner side of the frame corresponding to the accommodating space, and the light of a specific color emitted by the light emitting diode thereon is projected to the color light sensing component, and one of the light When the color light sensing element is completely shielded by a foreign object (such as a finger), the pressing signal is transmitted to the control unit because the light projected by the light emitting diode is not received, so that the control unit can Pressing the signal to determine the position pressed by the user and executing the corresponding control program, so that the touch button device of the present invention does not need to use the elastic member in the conventional mechanical button completely to avoid aging due to the elastic member. The shortcomings of the malfunctions do not require the use of a high-cost liquid crystal touch panel, that is, the effect and purpose of the flat touch buttons can be specifically realized.

For your convenience, the review committee can make a further understanding and understanding of the purpose, technical features and effects of the present invention. The embodiments are combined with the drawings, and the details are as follows:

The invention is a touch button device with a light-emitting diode arranged in a ring, mainly because the light-emitting diode has many advantages, such as: energy-saving effect, low cost, long service life, etc., therefore, the inventor adopts the light-emitting two A new type of touch button device has been redesigned in a polar body. In a preferred embodiment of the present invention, please refer to FIGS. 2 and 3, and FIG. 2 is a touch button applied to the security system. The front view of the device 2, and the third view is a schematic cross-sectional view of the touch button device 2, but the foregoing drawings are merely for convenience of description, for the general public or the practitioner of the art to quickly understand the essence of the disclosed content of the present invention. The gist of the present invention is not limited to the foregoing hardware style, and those skilled in the art can achieve the object of the present invention by utilizing other structures or devices of different styles after grasping the main technical features of the present invention. Therefore, the scope of the patent application should include equivalent structures without departing from the spirit and scope of the invention.

The touch button device 2 includes a control unit 21, a button substrate 23, a frame 25, and at least one light-emitting diode strip 27, wherein one of the button substrates 23 is included in the second and third embodiments. At least one color light sensing element 231 is disposed on the side surface, and each of the color light sensing elements 231 is electrically connected to the control unit 21, as shown in FIG. 4, which is a color light sensing element 231. And the circuit diagram of the control unit 21, when the color light sensing element 231 receives a specific color light source (such as: red light), the transistor Q is turned on, so that the control unit 21 receives a low potential signal. On the other hand, when the color light sensing element 231 does not receive a specific color light source, the transistor Q is in an off state, so that the control unit 21 receives a high potential signal, and thus, the control unit 21 can Based on the received high potential signal or low potential signal, it is determined whether the color light sensing element 231 has received a specific color light source, and executes a corresponding program, but in other embodiments of the present invention, the operator were able Production needs, the use of different elements, so that the control unit 21 determines the potential of the different signal and the above-described embodiment, the first engagement Chen.

In addition, as shown in FIG. 3, the frame 25 is a hollow frame (such as the rectangular frame of FIG. 2), and an accommodation space 250 is formed around the frame substrate 23, and the button substrate 23 can be assembled to the frame 25. Corresponding to one side of the accommodating space 250, and the color light sensing elements 231 can be completely located in the accommodating space 250. However, in other embodiments of the present invention, the frame 25 and the button substrate The connection mode of 23 is not limited to that shown in FIG. 3, as long as one side of the frame 25 can be assembled to the button substrate 23, and all the color light sensing elements 231 and 233 are positioned in the accommodating space. In addition, the light-emitting diode light strip 27 is annularly assembled to the inner side of the frame 25 corresponding to the accommodating space 250 and away from one side of the button substrate 23, and includes a circuit board. 270 and a plurality of light-emitting diodes 271, the light-emitting diodes 271 illuminate a specific light in the direction of the accommodating space 250, and the light emitted by the light-emitting diodes 271 is projected to the color light-sensing elements 231. So that the color light sensing element 231 can receive the light emitting diodes 271 Light of a specific color is emitted, and a high-potential signal is continuously transmitted to the control unit 21, and since the light-emitting diode strips 27 are ring-assembled and assembled to the inner side of the frame 25, that is, the light-emitting two The polar body 271 is a light-emitting line surrounding the accommodating space 250, so that the user can provide a good lighting effect not only at night or in poor ambient light, so that the user can clearly see the button substrate. The text or symbol on one side of the 23 (such as the number shown in FIG. 2), at the same time, the control unit 21 can also determine that all the color light sensing elements 231 have received the light of a specific color, except In addition, in order to improve the detection effect of the color light sensing element 231, the position of the LED light bar 27 is higher than the position of the color light sensing element 231, that is, the light emitting diodes. The light emitted by 271 is not blocked by the color light sensing element 231, so that the color light sensing element 231 located at the center of the button substrate 23 cannot receive light of a specific color.

In addition, as shown in FIGS. 2 and 3, when the area of the button substrate 23 is large, or the light-emitting diode 271 is low in brightness, the color light sensing element is effectively collected for external light. 231 can still be covered by a lens 233, so that the external light must be refracted by the lens 233 before being received by the corresponding color light sensing element 231, effectively achieving the effect of collecting light, avoiding the distance of the light The color light sensing element 231 that is farther away from the polar body 271 is erroneous due to the weak light of the received specific color. Moreover, with the overall design of the touch button device 2 of the present invention, when the user wants to input a password (for example, 5588), if the touch button device 2 is provided with the lens 233, the user can directly use the finger in sequence. The lens 233 corresponding to the symbol is pressed. At this time, since the muscle on the finger has elasticity, it can change along the outer shape of the lens 233, so that the lens 233 is completely covered and shielded when the lens 233 is completely shielded by the finger. The color light sensing element 231 corresponding to the lens 233 transmits a pressing signal (eg, a high potential) to the control unit 21 because the light of a specific color projected by the LED 271 is not received. After receiving the pressing signal in sequence, the position of the lens 233 pressed by the user is determined, and the number corresponding to the position pressed by the user is displayed on a display panel 28, and corresponding control is performed. The program (eg, the threshold for opening the control), although the user presses one of the lenses 233, it blocks the light of the light-emitting diode 271 in one direction, causing the color light sensing element 231 corresponding to the direction. The method receives light of a specific color, but since the LED strip 27 of the present invention is looped along the accommodating space, the lens 233 that is not pressed by the user can still receive other directions. The light of a specific color is used to avoid the occurrence of the error of the control unit 21. Therefore, the touch button device 2 of the present invention does not need to use the elastic member in the conventional mechanical button, so as to avoid the occurrence of the aging of the elastic member. The shortcoming of the malfunction, and the lens 233 or the color light sensing element 231 does not have any displacement or actuation relationship during the pressing of the lens 233. Therefore, the touch button is used for a long time. The device 2 also has no problem of component wear, which effectively improves the service life of the product.

In addition, since the lenses are assembled one by one on a plurality of color light sensing elements, the time in the process is prolonged. Therefore, in another preferred embodiment of the present invention, the operator can change the style of the lens, see section 5. In the figures, since most of the elements in the following embodiments have the same connection relationship, the same elements are still used in the same element numbers, and the connection relationship between them is not described here. Only the new elements are numbered. And description, combined with Chen Ming. A glass substrate 31 is disposed on one side of the button substrate 23, and the glass substrate 31 is located in the accommodating space 250. A lens 311 is formed corresponding to the position of each of the color light sensing elements 231, and the glass substrate 31 is formed. The inner side is provided with a recess 310 at a position corresponding to the color light sensing element 231, so that the color light sensing element 231 can be accommodated in the recess 310. Further, the glass substrate 31 does not correspond to the outer side of the lens 311. A shielding layer 313 is disposed at the position, and the shielding layer 313 can block the light of a specific color, so that the light of the specific color cannot penetrate the shielding layer 313, or the light of the other color can be converted after the shielding layer 313 is penetrated. However, in other embodiments of the present invention, the operator can also provide the shielding layer 313 on the side of the side surface of the groove 310, or directly perform the opaque treatment on the position of the glass substrate 31 that does not correspond to the lens 311. It is not limited to the case where the shielding layer 313 is provided on the outer side, which will be described first. Thus, when the user presses the glass substrate 31 with a finger and blocks one of the lenses 311, the color light sensing element 231 corresponding to the lens 311 transmits a pressing signal to the light of a specific color. The control unit 21 can execute the corresponding program according to the pressing signal. At the same time, since the glass substrate 31 and the lens 311 are integrally formed, the glass substrate 31 and the key substrate 23 can be quickly mounted. And forming the lens 311 at the position corresponding to the color light sensing element 231, and without using a high-cost liquid crystal touch panel, the purpose of the planar touch can be specifically realized, thereby greatly reducing the production cost of the manufacturer, and When one of the color light sensing elements 231 is damaged, the operator only needs to replace the corresponding components, and does not need to replace the whole as in the conventional liquid crystal touch panel, thereby effectively reducing the cost of maintenance for the user.

The above is only the preferred embodiment of the present invention, but the scope of the claims of the present invention is not limited thereto, and according to those skilled in the art, according to the technical content disclosed in the present invention, Equivalent changes that are easily considered are within the scope of protection of the invention.
