Description

[0002] Keyboards are widely used in various industries. They are used in conjunction with host computers, displays and other devices to control and detect the operation of corresponding devices. In certain environments, keyboards need to have an anti-mis-touch function, that is, when the operator is pressing the target key, the keyboard has the function of preventing non-target keys from being pressed.

[0003] For example, in high-temperature industrial environments such as atomic layer deposition technology research and development, glass manufacturing, and casting, R&D personnel need to frequently come into contact with high-temperature equipment (such as furnaces, molds, etc.), and also need to operate computers to adjust process parameters and record data or monitor processes.

[0004] Since a large amount of high-temperature vapor and liquid will be generated when the equipment is running, it is necessary to wear heat-insulating gloves. However, most heat-insulating gloves are relatively thick, which causes R&D personnel to often make accidental touches when operating the computer keyboard. That is, when pressing the target key, they will accidentally touch the surrounding non-target keys. If the gloves are frequently taken off and put on, it will affect the progress of the experiment and consume the patience of the R&D personnel.

DETAILED DESCRIPTION

[0019] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0020] like Figure 1-3 As shown, the present invention provides an anti-mistouch heat dissipation keyboard, including a keyboard body 100, an air source 200 and a plurality of key modules 300, the keyboard body 100 is provided with a plurality of key slots 111, the plurality of key slots 111 are interconnected to form a flow channel, and the two sides of the keyboard body 100 are respectively provided with a flow channel air inlet 112 and a flow channel air outlet 113 connected to the two ends of the flow channel; the air source 200 is installed at the flow channel air inlet 112 of the keyboard body 100; the plurality of key modules 300 are respectively arranged in the plurality of key slots 111, and each key module 30 0 includes an upper button 310, a lower button 320 and a driving member 330. The upper button 310 and the lower button are movably connected and enclose a cavity. The upper button 310 is provided with a button air outlet 311 connected to the cavity, and the lower button 320 is provided with a main air inlet 321 connected to the cavity and the flow channel. The driving member 330 is installed on the upper button 310 and / or the lower button 320, and is used to drive the upper button 310 and the lower button 320 to move relative to each other to a first state in which the main air inlet 321 is closed and a second state in which the main air inlet 321 is connected to the flow channel.

[0021] During implementation, after the keyboard is powered on, multiple driving components 330 control the upper button 310 and the lower button 320 to move relative to each other to the first state in which the main air inlet 321 is closed. At this time, the airflow generated by the wind source 200 does not enter the interior of the button module 300 but only flows in the flow channel, which is used to dissipate heat from the internal structure of the keyboard body 100. When the target button module 300 is triggered, the non-target button module 300 around the target button module 300 is in the second state, that is, the interior of the non-target button module 300 is connected to the flow channel through the main air inlet 321. At this time, part of the airflow generated by the wind source 200 enters the target button module 300 and is discharged from the button outlet 311. Under the impact of the above-mentioned airflow, the damping of the non-target button module 300 is relatively large, which can effectively prevent the non-target button module 300 from being accidentally touched.

[0022] The keyboard body 100 in this embodiment includes a flow channel plate 110 and a chip module 120. The flow channel plate 110 is fixedly arranged above the chip module 120. A plurality of key grooves 111, a flow channel air inlet 112 and a flow channel air outlet 113 are formed on the flow channel plate 110. A plurality of transverse through holes 114 and a plurality of longitudinal through holes 115 are opened on the flow channel plate 110. Two adjacent key grooves 111 along the transverse direction are connected via the transverse through hole 114, and two adjacent key grooves 111 along the longitudinal direction are connected via the longitudinal through hole 115.

[0023] It is understandable that the size of the key slot 111 should be compatible with the size of the key module 300, so that the key module 300 can slide in the key slot 111 along the vertical direction, thereby triggering the chip module 120 below. In the embodiment of the present invention, the shape and specific arrangement position of the above-mentioned transverse through hole 114 and longitudinal through hole 115 are not limited, as long as the multiple key slots 111 can be connected to each other.

[0024] In this embodiment, according to the usage habits of the keys, the number of the flow channel air inlets 112 is six, and the six flow channel air inlets 112 are evenly arranged on one side of the flow channel plate 110, while the key module 300 near the other side of the flow channel plate 110 is less frequently used, so the flow channel air outlets 113 are set to two and are arranged directly opposite to the key module 300 representing the numbers. Of course, in other embodiments, the number and setting positions of the flow channel air inlets 112 and the flow channel air outlets 113 can be determined according to specific needs.

[0025] In one embodiment, the chip module 120 includes a base, a first circuit board, a diaphragm and a second circuit board stacked in sequence in a vertical upward direction. The diaphragm is provided with a plurality of through holes corresponding to a plurality of upper buttons 310. The first circuit board and the second circuit board are both provided with contacts extending into the plurality of through holes. When the upper button 310 moves downward, the contacts at corresponding positions on the first circuit board and the second circuit board come into contact.

[0026] It is understandable that the chip module 120 may also use a spring or other structure to improve the reset function of the second circuit board. At the same time, it should be noted that the chip module 120 is a keyboard structure that can be thought of by those skilled in the art. By pressing the key module 300, the chip module 120 can be triggered to operate. At the same time, it is not a part to be improved in the embodiment of the present invention, so it will not be elaborated on in detail.

[0027] To facilitate triggering the chip module 120, in this embodiment, the button module 300 also includes a pressure rod 313, the top end of the pressure rod 313 is fixedly connected to the upper button 310, and the bottom end of the pressure rod 313 passes through the lower button 320 and abuts against the contact portion of the second circuit board.

[0028] To prevent the key module 300 from being separated from the key slot 111, in this embodiment, the keyboard body 100 also includes a limit cover 130, the bottom of which is fixedly connected to the flow channel plate 110, and the limit cover 130 is provided with limit grooves corresponding to the multiple key slots 111, and the length and width of the limit grooves are respectively smaller than the length and width of the corresponding key slots 111. The key module 300 also includes a limit block 314 fixedly connected to the side wall of the upper key 310, and the limit block 314 and the limit groove are staggered in the vertical direction.

[0029] like Fig. 9 As shown, the top of the base is recessed downward to facilitate the insertion of the flow channel plate 110 in the base. At the same time, a first opening 121 is provided on one side of the base for the air source 200 to pass through, and a second opening 122 is provided on the other side of the base to connect multiple flow channel outlets.

[0030] like Figure 8 As shown, in order to facilitate the heat dissipation function of the chip module 120 in the keyboard body 100, this embodiment is realized by a wind source 200. Among them, the wind source 200 includes a plurality of fans 210, an adapter 220 and a cover plate 230. The adapter 220 has a conical guide channel that gradually expands in the direction away from the flow channel. One side of the adapter 220 is connected to the flow channel air inlet 112 of the keyboard body 100, and the other side of the adapter 220 is fixedly connected to the cover plate 230. The plurality of fans 210 are installed on the cover plate 230 and connect the guide channel with the outside.

[0031] It can be understood that the adapter 220 has a wind gathering effect and can evenly deliver the airflow generated by multiple fans 210 to the flow channel of the flow channel plate 110. The cover plate 230 provides support for the installation of the fans 210 and closes the air inlet surface of the adapter 220. Of course, in other preferred embodiments, the wind source 200 can also adopt a tubular structure to achieve airflow delivery.

[0032] When the keyboard is powered on, multiple driving components 330 control the upper button 310 and the lower button 320 to move relative to each other to the first state where the main air inlet 321 is closed. At this time, the airflow generated by the wind source 200 does not enter the button module 300 but only flows in the flow channel to dissipate heat from the internal structure of the keyboard body 100.

[0033] In order to achieve the function of preventing accidental touches, the key module 300 in this embodiment is combined with the structure of the wind source 200 and the flow channel plate 110 to improve the damping of non-target keys, thereby achieving the function of preventing accidental touches.

[0034] In one embodiment, the bottom of the upper button 310 is recessed inward to form a first cavity, the upper portion of the upper button 310 is formed with a button air outlet 311 connected to the first cavity, the top of the lower button 320 is recessed inward to form a second cavity, the lower button 320 is inserted into the first cavity of the upper button 310 and slides relative to the upper button 310, and a main air inlet 321 is formed on the side wall of the lower button 320 close to the flow channel air inlet 112, and the main air inlet 321 is connected to the second cavity.

[0035] That is, a pattern is formed in which the upper button 310 wraps the lower button 320. When the lower button 320 moves upward to a position where it is completely built into the upper button 310, the main air inlet 321 is completely blocked by the upper button 310. At this time, the interior of the button module 300 is separated from the flow channel. When the lower button 320 moves downward, the portion of the main air inlet 321 that is not blocked by the upper button 310 becomes larger and larger, and the main air inlet 321 is connected to the flow channel. By controlling the downward movement distance of the lower button 320, the cross-sectional size of the main air inlet 321 connecting to the channel can be controlled, thereby controlling the size of the airflow diverted to the button module 300.

[0036] Of course, in other preferred embodiments, the button module 300 may also adopt a method in which the lower button 320 includes the upper button 310, which can also achieve the creative intention of the embodiment of the present invention. At the same time, other movement modes may also be adopted, such as horizontal sliding, etc., as long as the connection and disconnection between the inside of the button module 300 and the flow channel can be controlled, and the embodiment of the present invention does not limit this.

[0037] like Figure 4-5 As shown, in order to facilitate the relative movement between the upper button 310 and the lower button 320, the driving member 330 in this embodiment includes a first electromagnet 331 and a first permanent magnet 332. A first slide groove 312 is opened on the side wall of the upper button 310. The first permanent magnet 332 is fixedly connected to the side wall of the lower button 320 and is slidably connected to the first slide groove 312. The first electromagnet 331 is installed at the bottom and / or top of the first slide groove 312.

[0038] When a first directional current is supplied to the first electromagnet 331 , the lower button 320 moves toward the upper button 310 under the magnetic force of the first electromagnet 331 and the first permanent magnet 332 until it is in the first state where the main air inlet 321 is closed.

[0039] When the first electromagnet 331 is supplied with a current in the second direction, the lower button 320 moves away from the upper button 310 under the magnetic force of the first electromagnet 331 and the first permanent magnet 332 until it is in the second state where the main air inlet 321 is connected to the flow channel.

[0040] It is understandable that by changing the direction of the current flowing into the first electromagnet 331 (ie, the first direction current and the second direction current flow in opposite directions), the first electromagnet 331 and the first permanent magnet 332 can be attracted or repelled.

[0041] To further improve the stability of the relative movement between the upper button 310 and the lower button 320, in this embodiment, there are two first electromagnets 331 in each first slide groove 312, and the two first electromagnets 331 are respectively arranged at the top and bottom of the first slide groove 312, and the magnetic properties of the two first electromagnets 331 on opposite sides are oppositely arranged.

[0042] It is understandable that the driving member 330 can also be implemented by a linear motor or other structures in principle. However, the electromagnet and permanent magnet are used in this embodiment, which has the advantages of small size and convenient control of the direction of movement.

[0043] In order to avoid that most of the air flow is discharged from the flow channel air outlet 113 and less air flow enters the key module 300, in one embodiment, it also includes a solenoid valve installed at the flow channel air outlet 113 of the keyboard body 100. Therefore, when the key module 300 is triggered, the solenoid valve closes the flow channel air outlet 113, so that the air flow in the flow channel can only be discharged from the key outlet 311 of the upper key 310.

[0044] Through the setting of the above-mentioned driving member 330, when the target button module 300 is triggered, the non-target button module 300 around the target button module 300 is in the second state, that is, the interior of the non-target button module 300 is connected with the flow channel through the main air inlet 321. At this time, part of the airflow generated by the wind source 200 enters the target button module 300 and is discharged from the button air outlet 311. Under the impact of the above-mentioned airflow, the damping of the non-target button module 300 is relatively large, which can effectively prevent the non-target button module 300 from being accidentally touched.

[0045] It is understandable that the non-target key modules 300 may be all the remaining key modules 300, or may be several key modules 300 around the target key module 300. Figure 7 As shown, when the button module 300 labeled 5 is triggered, the surrounding buttons labeled 1, 2, 3, 4, 6, 7, 8, and 9 are non-target button modules 300. At this time, it is only necessary to pass the second direction current through the first electromagnet 331 in the above 8 non-target button modules 300, so that the upper button 310 in the above 8 non-target button modules 300 will produce a strong damping feeling under the impact of the airflow, thereby realizing the function of preventing accidental touch.

[0046] Since the fan 210 is installed at the air inlet 112 of the flow channel, the distances from the source of the airflow to the button modules 300 in different directions are different. Therefore, under normal circumstances, the airflow entering the button modules 300 numbered 1, 4, and 7 is greater than the airflow entering the button modules 300 numbered 2 and 8, and even greater than the airflow entering the button modules 300 numbered 3, 6, and 9. Therefore, the non-target button modules 300 around the target button module 300 numbered 5 will produce three different types of damping.

[0047] In order to make the damping generated by the eight surrounding non-target key modules 300 similar.

[0048] In one embodiment, three auxiliary air inlets 322 are further opened on the surrounding side of the lower button 320. The three auxiliary air inlets 322 and the main air inlet 321 are respectively arranged on the surrounding sides of the lower button 320. The button module 300 also includes three air volume adjustment components 340 respectively installed on the three auxiliary air inlets 322. The three air volume adjustment components 340 are used to adjust the size of the auxiliary air inlets 322.

[0049] like Figure 5-6 As shown, the air volume adjustment member 340 includes a wind resistance adjustment door 341, a second permanent magnet 342 and a second electromagnet 343. The wind resistance adjustment door 341 is slidably set in the corresponding auxiliary air inlet 322 to adjust the opening size at the bottom of the auxiliary air inlet 322. The second permanent magnet 342 is installed on the wind resistance adjustment door 341. The second permanent magnet 342 is slidably connected to the second slide groove 323 opened on the lower button 320. The second electromagnet 343 is installed in the second slide groove 323 and is arranged opposite to the second permanent magnet 342.

[0050] When the third directional current is supplied to the second electromagnet 343, under the magnetic force of the second electromagnet 343 and the second permanent magnet 342, the wind resistance adjustment door 341 moves toward the direction close to the upper button 310 until it is in the third state where the auxiliary air inlet 322 is fully opened.

[0051] When a fourth directional current is supplied to the second electromagnet 343 , the windage regulating door 341 moves away from the upper button 310 under the magnetic force of the second electromagnet 343 and the second permanent magnet 342 until it is in the fourth state where the auxiliary air inlet 322 is completely closed.

[0052] It can be understood that by changing the direction of the current flowing into the second electromagnet 343 (ie, the third direction current and the fourth direction current flow in opposite directions), the second electromagnet 343 and the second permanent magnet 342 can be attracted or repelled.

[0053] The key modules 300 labeled 1, 4, and 7 are subject to the greatest wind resistance compared to other key modules 300, so only the main air inlet 321 is opened, and the other auxiliary air inlets 322 are closed; The key modules 300 with reference numbers 2 and 8 have smaller wind resistance than the key modules 300 with reference numbers 1, 4, and 7. Therefore, in addition to the main air inlet 321 being opened, the auxiliary air inlets 322 of the two close to the side with reference number 5 are all opened, and the other auxiliary air inlets 322 are closed; The key modules 300 labeled 3, 6, and 9 have the lowest wind resistance, so in addition to the main air inlet 321 being opened, the three auxiliary air inlets 322 thereon are all opened.

[0054] The air volume adjusting member 340 can be used to further adjust the air intake resistance of the key module 300 , so that the air intake volumes of the non-target key modules 300 around the target key module 300 are similar, and thus the damping is similar.

[0055] The present embodiment also includes a control component 400, which is electrically connected to the chip module 120 and multiple driving components 330. When the target button module 300 triggers the chip module 120, the control component 400 receives the sensing signal and determines the triggering position, and the control component 400 controls the driving components 330 of multiple button modules 300 around the corresponding position to act, thereby realizing the above control process. It can be understood that the above control component 400 can use a control chip, which is installed in the installation groove 116 opened on the flow channel plate 110. It is a structure that can be thought of by those skilled in the art, and no further elaboration and explanation will be given here.

[0056] Compared with the prior art: after the keyboard is powered on, multiple driving parts 330 control the upper button 310 and the lower button 320 to move relative to each other to the first state in which the main air inlet 321 is closed. At this time, the airflow generated by the wind source 200 does not enter the interior of the button module 300 but only flows in the flow channel, which is used to dissipate heat from the internal structure of the keyboard body 100. When the target button module 300 is triggered, the non-target button module 300 around the target button module 300 is in the second state, that is, the interior of the non-target button module 300 is connected to the flow channel through the main air inlet 321. At this time, part of the airflow generated by the wind source 200 enters the target button module 300 and is discharged from the button outlet 311. Under the impact of the above-mentioned airflow, the damping of the non-target button module 300 is relatively large, which can effectively prevent the non-target button module 300 from being accidentally touched.

[0057] 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 changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
