Description

Technical Field

[0001] The present invention relates to the technical field of keyboards, and particularly to an anti-misoperation heat dissipation keyboard. Background Art

[0002] Keyboards are widely used in various industries. When used in conjunction with devices such as hosts and monitors, they can implement control and detect the operation of corresponding devices. In specific environments, keyboards need to have an anti-misoperation function, that is, during the process of an operator pressing a 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, researchers need to frequently contact high-temperature equipment (such as furnaces, molds, etc.), and at the same time need to operate a computer to adjust process parameters, record data, or monitor processes.

[0004] Since a large amount of high-temperature steam and liquid are generated during the operation of the equipment, heat-insulating gloves need to be worn. However, most heat-insulating gloves are relatively thick, which often causes misoperation when researchers operate the computer keyboard, that is, when pressing the target key, non-target keys around it will be accidentally pressed. If gloves are frequently removed and put on, it will affect the experimental progress and consume the patience of researchers.

[0005] Therefore, there is an urgent need for an anti-misoperation heat dissipation keyboard to solve the problem that non-target keys are accidentally pressed when pressing the target key. Summary of the Invention

[0006] In view of this, it is necessary to provide an anti-misoperation heat dissipation keyboard to solve the problem that non-target keys are accidentally pressed when pressing the target key due to factors such as wearing heat-insulating gloves.

[0007] The present invention provides an anti-misoperation heat dissipation keyboard, including a keyboard body, a wind source, and a plurality of key modules. A plurality of key slots are opened on the keyboard body, and the plurality of key slots communicate with each other to form a flow channel. A flow channel air inlet and a flow channel air outlet connected to both ends of the flow channel are respectively opened on both sides of the keyboard body; the wind source is installed at the flow channel air inlet of the keyboard body; the plurality of key modules are respectively arranged in the plurality of key slots, and each key module includes an upper key, a lower key, and a driving member. The upper key and the lower key are movably connected in cooperation and enclose a cavity. An air outlet of the key is opened on the upper key to communicate with the cavity, and a main air inlet communicating with the cavity and the flow channel is opened on the lower key. The driving member is installed on the upper key and / or the lower key and is used to drive the upper key and the lower key to move relative to each other to a first state where the main air inlet is closed and a second state where the main air inlet communicates with the flow channel.

[0008] Further, the bottom of the upper button is recessed inward to form a first cavity, and an air outlet of the button is formed at the upper part of the upper button and is communicated with the first cavity. The top of the lower button is recessed inward to form a second cavity. The lower button is inserted into the first cavity of the upper button and slides relative to the upper button. A main air inlet is formed on the side wall of the lower button close to the air inlet of the flow channel, and the main air inlet is communicated with the second cavity.

[0009] Further, the driving member includes a first electromagnet and a first permanent magnet. A first sliding groove is formed on the side wall of the upper button. The first permanent magnet is fixedly connected to the side wall of the lower button and is slidably connected to the first sliding groove. The first electromagnet is installed at the bottom and / or the top of the first sliding groove.

[0010] Wherein, when a current in a first direction is applied to the first electromagnet, under the magnetic force of the first electromagnet and the first permanent magnet, the lower button moves in a direction close to the upper button until it is in a first state where the main air inlet is closed.

[0011] When a current in a second direction is applied to the first electromagnet, under the magnetic force of the first electromagnet and the first permanent magnet, the lower button moves in a direction away from the upper button until it is in a second state where the main air inlet is communicated with the flow channel.

[0012] Further, three auxiliary air inlets are formed on the peripheral side of the lower button. The three auxiliary air inlets and the main air inlet are respectively arranged around the lower button. The button module further includes three air volume adjusting members respectively installed at the three auxiliary air inlets, and the three air volume adjusting members are used to adjust the sizes of the auxiliary air inlets.

[0013] Further, the air volume adjusting member includes a wind resistance adjusting door, a second permanent magnet, and a second electromagnet. The wind resistance adjusting door is slidably arranged in the corresponding auxiliary air inlet to adjust the opening size of the bottom of the auxiliary air inlet. The second permanent magnet is installed on the wind resistance adjusting door. The second permanent magnet is slidably connected to a second sliding groove formed on the lower button, and the second electromagnet is installed in the second sliding groove and is arranged opposite to the second permanent magnet.

[0014] Wherein, when a current in a third direction is applied to the second electromagnet, under the magnetic force of the second electromagnet and the second permanent magnet, the wind resistance adjusting door moves in a direction close to the upper button until it is in a third state where the auxiliary air inlet is fully opened.

[0015] When a current in a fourth direction is applied to the second electromagnet, under the magnetic force of the second electromagnet and the second permanent magnet, the air resistance adjusting door moves away from the upper button until it reaches a fourth state where the auxiliary air inlet is completely closed.

[0016] Further, the keyboard body includes a flow channel plate and a chip module. The flow channel plate is fixedly arranged above the chip module. A plurality of the key grooves, the flow channel air inlet, and the flow channel air outlet are formed on the flow channel plate. A plurality of transverse through holes and a plurality of longitudinal through holes are provided on the flow channel plate. Adjacent two of the key grooves in the transverse direction are connected through the transverse through holes, and adjacent two of the key grooves in the longitudinal direction are connected through the longitudinal through holes.

[0017] Further, the chip module includes a base, a first circuit board, a diaphragm, and a second circuit board stacked in sequence in the vertically upward direction. A plurality of through holes corresponding to the plurality of upper buttons one by one are provided on the diaphragm. Contacts extending into the plurality of through holes are provided on both the first circuit board and the second circuit board. When the upper button moves downward, the contacts at corresponding positions on the first circuit board and the second circuit board come into contact.

[0018] Further, the key module further includes a pressing rod. The top end of the pressing rod is fixedly connected to the upper button, and the bottom end of the pressing rod passes through the lower button and abuts against the contact part of the second circuit board.

[0019] Further, the air source includes a plurality of blowers, an adapter, and a cover plate. A tapered diversion channel that gradually expands in a direction away from the flow channel is formed inside the adapter. One side of the adapter is connected to the flow channel air inlet of the keyboard body, and the other side of the adapter is fixedly connected to the cover plate. The plurality of blowers are installed on the cover plate and connect the diversion channel and the outside.

[0020] Further, a control component is further included. The control component is electrically connected to the chip module and the plurality of driving members.

[0021] Compared with the prior art, after the keyboard is powered on, the plurality of driving members control the relative movement of the upper button and the lower button to a first state where the main air inlet is closed. At this time, the air flow generated by the air source does not enter the inside of the key module and only flows in the flow channel, which is used for dissipating heat from the internal structure of the keyboard body. When the target key module is triggered, the non-target key modules around the target key module are in a second state, that is, the inside of the non-target key modules is connected to the flow channel through the main air inlet. At this time, part of the air flow generated by the air source enters the target key module and is discharged from the key air outlet. Under the impact of the above air flow, the damping of the non-target key modules is large, which can effectively prevent the non-target key modules from being accidentally touched.

[0031] Next, the preferred embodiments of the present invention will be specifically described in conjunction with the accompanying drawings. The accompanying drawings form a part of this application and are used together with the embodiments of the present invention to explain the principle of the present invention, rather than to limit the scope of the present invention.

[0032] Such as Figures 1-3As shown in the figure, a touch - prevention and heat - dissipation keyboard provided by the present invention includes a keyboard body 100, an air source 200, and a plurality of key modules 300. A plurality of key grooves 111 are formed on the keyboard body 100. The plurality of key grooves 111 communicate with each other to form a flow channel. A flow - channel air inlet 112 and a flow - channel air outlet 113 connected to both ends of the flow channel are respectively formed on both sides of the keyboard body 100. 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 disposed in the plurality of key grooves 111. Each key module 300 includes an upper key 310, a lower key 320, and a driving member 330. The upper key 310 is movably connected to the lower key in cooperation and encloses a cavity. An air - outlet opening 311 communicating with the cavity is formed on the upper key 310. A main air - inlet opening 321 communicating with the cavity and the flow channel is formed on the lower key 320. The driving member 330 is installed on the upper key 310 and / or the lower key 320 and is used to drive the upper key 310 and the lower key 320 to move relative to each other to a first state where the main air - inlet opening 321 is closed and a second state where the main air - inlet opening 321 communicates with the flow channel.

[0033] During implementation, after the keyboard is powered on, the plurality of driving members 330 control the upper key 310 and the lower key 320 to move relative to each other to the first state where the main air - inlet opening 321 is closed. At this time, the air flow generated by the air source 200 does not enter the interior of the key module 300 and only flows in the flow channel, which is used to dissipate heat from the internal structure of the keyboard body 100. When the target key module 300 is triggered, the non - target key modules 300 around the target key module 300 are in the second state, that is, the interior of the non - target key module 300 is connected to the flow channel through the main air - inlet opening 321. At this time, part of the air flow generated by the air source 200 enters the target key module 300 and is discharged from the air - outlet opening 311. Under the impact of the above - mentioned air flow, the damping of the non - target key module 300 is relatively large, which can effectively prevent the non - target key module 300 from being accidentally touched.

[0034] 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 disposed 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 formed on the flow - channel plate 110. Adjacent two key grooves 111 in the transverse direction are connected through the transverse through - holes 114, and adjacent two key grooves 111 in the longitudinal direction are connected through the longitudinal through - holes 115.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] like Figure 9As shown in the figure, the top of the base is recessed downward to facilitate the clamping of the flow channel plate 110 in the base. At the same time, a first opening 121 for the air source 200 to pass through is provided on one side of the base, and a second opening 122 communicating with a plurality of flow channel outlets is provided on the other side of the base.

[0042] As Figure 8 As shown in the figure, in order to facilitate the realization of the heat dissipation function of the chip module 120 in the keyboard body 100, this implementation scheme is realized through the air source 200. Among them, the air source 200 includes a plurality of fans 210, an adapter 220 and a cover plate 230. A tapered diversion channel that gradually expands along the direction away from the flow channel is formed inside the adapter 220. 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 communicate the diversion channel with the outside.

[0043] It can be understood that the above-mentioned adapter 220 has the effect of gathering wind, and can evenly transport the air flow generated by the plurality of fans 210 into the flow channels of the flow channel plate 110. The cover plate 230 provides a bearing for the installation of the fans 210 and closes the air inlet surface of the adapter 220. Of course, in other preferred embodiments, the above-mentioned air source 200 can also adopt a tube structure or the like to realize the transportation of the air flow.

[0044] When the keyboard is powered on, a plurality of driving members 330 control the upper key 310 and the lower key 320 to move relative to each other to the first state where the main air inlet 321 is closed. At this time, the air flow generated by the air source 200 does not enter the inside of the key module 300 and only flows in the flow channels, which is used for dissipating heat from the internal structure of the keyboard body 100.

[0045] In order to realize the function of preventing accidental touch, the key module 300 in this implementation scheme is combined with the structures of the air source 200 and the flow channel plate 110 to increase the damping of non-target keys, so as to realize the function of preventing accidental touch.

[0046] In one embodiment, the bottom of the upper key 310 is recessed inward to form a first cavity. A key air outlet 311 communicating with the first cavity is formed in the upper part of the upper key 310. The top of the lower key 320 is recessed inward to form a second cavity. The lower key 320 is inserted into the first cavity of the upper key 310 and slides relative to the upper key 310. A main air inlet 321 is formed on the side wall of the lower key 320 close to the flow channel air inlet 112, and the main air inlet 321 communicates with the second cavity.

[0047] That is, a mode 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 inside of the button module 300 is separated from the flow channel. When the lower button 320 moves downward, the unblocked part of the main air inlet 321 by the upper button 310 becomes larger and larger, and the main air inlet 321 is connected to the flow channel. By controlling the distance that the lower button 320 moves downward, the cross-sectional area of the connection between the main air inlet 321 and the channel can be controlled, thereby controlling the size of the air flow diverted to the button module 300.

[0048] Of course, in other preferred embodiments, the button module 300 can also adopt the method in which the lower button 320 includes the upper button 310, and the creative intention in the embodiments of the present invention can also be achieved. At the same time, other movement modes can also be adopted, such as horizontal sliding, etc., as long as the on-off of the inside of the button module 300 and the flow channel can be controlled. The embodiments of the present invention do not limit this.

[0049] As Figures 4-5 shown, for the convenience of driving 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 sliding 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 sliding groove 312. The first electromagnet 331 is installed at the bottom and / or top of the first sliding groove 312.

[0050] Among them, when a first-direction current is passed through the first electromagnet 331, under the magnetic force of the first electromagnet 331 and the first permanent magnet 332, the lower button 320 moves in the direction close to the upper button 310 until it reaches the first state where the main air inlet 321 is closed.

[0051] When a second-direction current is passed through the first electromagnet 331, under the magnetic force of the first electromagnet 331 and the first permanent magnet 332, the lower button 320 moves in the direction away from the upper button 310 until it reaches the second state where the main air inlet 321 is connected to the flow channel.

[0052] It can be understood that by changing the direction of the current passed through the first electromagnet 331 (that is, the flow directions of the first-direction current and the second-direction current are opposite), the first electromagnet 331 and the first permanent magnet 332 can be attracted or repelled.

[0053] To further improve the stability of the relative movement between the upper button 310 and the lower button 320, in this embodiment, the number of the first electromagnets 331 in each first sliding groove 312 is two. The two first electromagnets 331 are respectively arranged at the top and the bottom of the first sliding groove 312, and the magnetic properties of the opposite sides of the two first electromagnets 331 are set to be opposite.

[0054] It can be understood that in principle, a linear motor or other structures can also be used to implement the above driving member 330. However, in this embodiment, the use of electromagnets and permanent magnets has the advantages of small volume and convenient control of the action direction.

[0055] To prevent most of the air flow from being discharged from the air outlet 113 of the flow channel and less air flow entering the button module 300, in one embodiment, it further includes a solenoid valve installed at the air outlet 113 of the flow channel of the keyboard body 100. Therefore, when the button module 300 is triggered, the solenoid valve closes the air outlet 113 of the flow channel, so that the air flow in the flow channel can only be discharged from the button air outlet 311 of the upper button 310.

[0056] Through the setting of the above driving member 330, after the target button module 300 is triggered, the non-target button modules 300 around the target button module 300 are 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 air flow generated by the air source 200 enters the target button module 300 and is discharged from the button air outlet 311. Under the impact of the above air flow, the damping of the non-target button module 300 is large, which can effectively prevent the non-target button module 300 from being accidentally touched.

[0057] It can be understood that the above non-target button module 300 can be all the remaining button modules 300, or several button modules 300 around the target button module 300. The following will be described with specific embodiments. For example Figure 7 As shown, when the button module 300 numbered 5 is triggered, the surrounding button modules numbered 1, 2, 3, 4, 6, 7, 8, 9 are non-target button modules 300. At this time, only by passing a current in the second direction through the first electromagnets 331 in the above 8 non-target button modules 300, a strong damping feeling can be generated for the upper buttons 310 in the above 8 non-target button modules 300 under the impact of the air flow, so as to achieve the function of preventing accidental touch.

[0058] Since the fan 210 is installed at the air inlet 112 of the flow channel, the source of the airflow is at different distances from the key modules 300 in different directions. Therefore, under normal circumstances, the airflow entering the key modules 300 numbered 1, 4, and 7 is more than that entering the key modules 300 numbered 2 and 8, and even more than that entering the key modules 300 numbered 3, 6, and 9. As a result, the non-target key modules 300 around the target key module 300 numbered 5 will generate three different damping forces.

[0059] In order to make the damping forces generated by the eight surrounding non-target key modules 300 similar.

[0060] In one embodiment, three auxiliary air inlets 322 are further provided on the peripheral side of the lower key 320. The three auxiliary air inlets 322 and the main air inlet 321 are respectively arranged around the lower key 320. The key module 300 further includes three air volume adjusting members 340 respectively installed at the three auxiliary air inlets 322, and the three air volume adjusting members 340 are used to adjust the sizes of the auxiliary air inlets 322.

[0061] As Figures 5-6 shown, among them, the air volume adjusting member 340 includes a wind resistance adjusting door 341, a second permanent magnet 342, and a second electromagnet 343. The wind resistance adjusting door 341 is slidably arranged in the corresponding auxiliary air inlet 322 to adjust the opening size of the bottom of the auxiliary air inlet 322. The second permanent magnet 342 is installed on the wind resistance adjusting door 341, and the second permanent magnet 342 is slidably connected to a second sliding groove 323 opened on the lower key 320. The second electromagnet 343 is installed in the second sliding groove 323 and is arranged opposite to the second permanent magnet 342.

[0062] Among them, when a third-direction current is passed through the second electromagnet 343, under the magnetic force of the second electromagnet 343 and the second permanent magnet 342, the wind resistance adjusting door 341 moves towards the direction close to the upper key 310 until it reaches the third state where the auxiliary air inlet 322 is fully opened.

[0063] When a fourth-direction current is passed through the second electromagnet 343, under the magnetic force of the second electromagnet 343 and the second permanent magnet 342, the wind resistance adjusting door 341 moves towards the direction away from the upper key 310 until it reaches the fourth state where the auxiliary air inlet 322 is fully closed.

[0064] It can be understood that by changing the direction of the current passed through the second electromagnet 343 (that is, the flow directions of the third-direction current and the fourth-direction current are opposite), the second electromagnet 343 and the second permanent magnet 342 can be attracted or repelled.

[0065] The key modules 300 labeled 1, 4, and 7 are subject to the greatest wind resistance compared to other key modules 300. Therefore, only the main air inlet 321 is opened, and the remaining auxiliary air inlets 322 are closed;

[0066] The key modules 300 labeled 2 and 8 have less wind resistance compared to the key modules 300 labeled 1, 4, and 7. Therefore, in addition to the main air inlet 321 being opened, the auxiliary air inlets 322 on the side close to label 5 of both are opened, and the remaining auxiliary air inlets 322 are closed;

[0067] The key modules 300 labeled 3, 6, and 9 have the lowest wind resistance. Therefore, in addition to the main air inlet 321 being opened, the three auxiliary air inlets 322 above them are all opened.

[0068] The air volume adjustment member 340 provided can 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.

[0069] This implementation also includes a control component 400, which is electrically connected to the chip module 120 and multiple driving members 330. When the target key module 300 triggers the chip module 120, the control component 400 receives the induction signal and determines the triggered position, and the control component 400 controls the driving members 330 of the multiple key modules 300 around the corresponding position to act, thus realizing the above control process. It can be understood that the above control component 400 can adopt a control chip, which is installed in the installation groove 116 opened on the flow channel plate 110, and its structure can be thought of by those skilled in the art, and no more elaboration and description will be made here.

[0070] Compared with the prior art: After the keyboard is powered on, multiple driving members 330 control the upper key 310 and the lower key 320 to move relative to each other to the first state where the main air inlet 321 is closed. At this time, the air flow generated by the air source 200 does not enter the key 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 key module 300 is triggered, the non-target key modules 300 around the target key module 300 are in the second state, that is, the inside of the non-target key module 300 is connected to the flow channel through the main air inlet 321. At this time, part of the air flow generated by the air source 200 enters the target key module 300 and is discharged from the key air outlet 311. Under the impact of the above air flow, the damping of the non-target key module 300 is larger, which can effectively prevent the non-target key module 300 from being accidentally touched.

[0071] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention.
