Description

Technical Field

[0001] The present invention relates to the field of computer keyboards, and particularly to an industrial keyboard suitable for high-temperature operations. Background Art

[0002] Currently, many high-precision experimental researches at home and abroad need to be carried out at a certain temperature. For example, the atomic layer deposition technology in the semiconductor field requires growing a coating on a wafer. However, during laboratory or industrial production processes, process engineers need to frequently adjust experimental parameters to obtain the best production process. Therefore, it is necessary to relatively frequently use heat-insulating gloves to turn on and off high-temperature equipment and replace experimental items therein, and register experimental data on a computer. If the heat-insulating equipment is frequently removed and worn, it will make the researchers feel irritated. However, for the existing anti-misoperation industrial keyboards, by impacting the keycaps with air flow, a certain damping is generated on the keycaps to achieve the anti-misoperation effect. However, due to the dense flow channels provided inside the keyboard, the energy dissipation of the air flow is too fast during the propagation process inside the keyboard, resulting in a relatively large damping for the keycaps close to the micro fan side, while a relatively small damping for the keycaps far from the micro fan side. The large damping difference between the two sides of the keyboard will affect the operation comfort and judgment accuracy of scientific researchers. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an industrial keyboard suitable for high-temperature operations to solve the problem of anti-misoperation.

[0005] Optionally, a return spring is sleeved between the key bracket and the sliding bracket.

[0006] Optionally, the air outlet module includes an air outlet bracket, with air flow opening and closing plates provided on both sides of the air outlet bracket.

At one end of the cavity of the friction drive mounting cover, a rear first friction electromagnet and a rear second friction electromagnet are provided, and at the other end, a front first friction electromagnet and a front second friction electromagnet are provided. When powered on, the front first friction electromagnet and the first friction permanent magnet generate opposite magnetic fields, and the second friction permanent magnet and the rear first friction electromagnet attract each other, driving the friction drive plate to drive the air flow opening and closing plate to open.

[0008] Optionally, sliding rails are provided at the bottom of the friction drive mounting cover. The friction drive plate is provided with a first support pillar and a second support pillar, and the first support pillar and the second support pillar slide in the sliding rails.

[0009] Optionally, a first compression spring is provided between one end of the sliding rail and the first support pillar, and a second compression spring is provided between the other end of the sliding rail and the second support pillar.

Furthermore, it ensures that the damping generated by the keycaps inside the entire keyboard during anti-misoperation is approximate. The present invention connects the diversion holes magnetically to the air resistance adjustment plate. By electrifying the electromagnetic, the air resistance adjustment plate is opened, reducing the damping of the key module, so that the air flow of the currently pressed key module is reduced, achieving anti-misoperation.

[0014] Adopting the design modes of friction drive, rotary opening and closing, and momentum neutralization makes the air outlet module at the tail of the keyboard more stable during opening and closing, without causing the keyboard to shake left and right. Preventing the keyboard from shifting can avoid misoperation by researchers and improve the stability of the keyboard. Brief Description of the Drawings

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific situations.

[0019] As Figures 1 - 10 shown, an industrial keyboard applicable to high-temperature operations is disclosed, including: The keyboard housing 7 is provided with a micro fan 1 at one end and an air outlet module 6 at the other end. The top of the keyboard housing 7 is elastically connected with a key module 2 through a key bracket 4, and a trackball 5 is provided at one end of the top. As Figure 4 and Figure 9 shown, inside the key module 2, there is a sensor and a sliding bracket 1601 connected to the key bracket 4. A diversion hole 1602 is provided on the side of the key module 2, and the diversion hole 1602 is magnetically connected with a wind resistance adjustment plate 15. When pressing the key module 2, the air outlet module 6 is closed, the electromagnetic is energized, the wind resistance adjustment plate 15 is opened, and the damping of the key module is reduced.

[0020] As Figure 7 and Figure 9 shown, in the specific implementation process of this embodiment, a first adjustment electromagnet 1604, a second adjustment electromagnet 1605, a third adjustment electromagnet 1606, and a fourth adjustment electromagnet 1607 are sequentially arranged from top to bottom on one side of the diversion hole 1602, and a wind resistance adjustment sliding groove 1603 is provided on the other side. A wind resistance adjustment spring 14 is provided in the wind resistance adjustment sliding groove 1603. A wind resistance adjustment permanent magnet 1501 is provided on one side of the wind resistance adjustment plate 15, and a moving convex block 1503 matched with the wind resistance adjustment sliding groove 1603 is provided on the other side. According to the distance between the key module 2 and the micro fan 1, by energizing multiple electromagnets, the opening size of the wind resistance adjustment plate 15 is realized to be opened.

[0021] In the initial situation, the first adjustment electromagnet 1604, the second adjustment electromagnet 1605, the third adjustment electromagnet 1606, and the fourth adjustment electromagnet 1607 on the key shell 16 are not energized. Therefore, under the action of the wind resistance adjustment spring 14, the moving convex block 1503 is pushed, so that the wind resistance adjustment permanent magnet 1501 contacts the first adjustment electromagnet 1604, the second adjustment electromagnet 1605, the third adjustment electromagnet 1606, and the fourth adjustment electromagnet 1607, and the wind resistance adjustment plate surface 1502 closes the diversion hole 1602, making the air flow unable to pass through the key module 2.

[0022] As Figure 1 shown, in the specific implementation process of this embodiment, a return spring 3 is sleeved between the key bracket 4 and the sliding bracket 1601, and it can automatically reset after pressing the key module 2.

[0023] As Figures 2 - 3 、 Figure 5 shown, in the specific implementation process of this embodiment, the air outlet module 6 includes an air outlet bracket 8. Air flow opening and closing plates 9 are provided on both sides of the air outlet bracket 8, and the air flow opening and closing plates 9 are connected with a driving mechanism, and the driving mechanism is arranged in the middle of the air outlet bracket 8.

[0024] Furthermore, Figure 8 As shown, the driving mechanism includes a friction drive mounting cover 12. A friction drive plate 10 for driving the air flow opening and closing plate 9 is magnetically connected to the bottom of the friction drive mounting cover 12. The friction drive plate 10 is divided into two left and right parts. One end of the friction drive plate 10 is provided with a first friction permanent magnet 1001, the other end is provided with a second friction permanent magnet 1003, and the top is slidably connected to the friction drive mounting cover 12. One end of the cavity of the friction drive mounting cover 12 is provided with a rear first friction electromagnet 1202 and a rear second friction electromagnet 1203, and the other end is provided with a front first friction electromagnet 1205 and a front second friction electromagnet 1206. When energized, the front first friction electromagnet 1205 generates an opposite magnetic field with the first friction permanent magnet 1001, and the second friction permanent magnet 1003 is attracted to the rear first friction electromagnet 1202, driving the friction drive plate 10 to drive the air flow opening and closing plate 9 to open.

[0025] When the air flow opening and closing plates 9 on both the left and right sides are closed and the air flow opening and closing plate mounting holes 801 are closed, at this time, the friction drive plates 10 are in a front and rear state in the two sliding guide rails 1204. In this embodiment, sliding guide rails 1204 are provided at the bottom of the friction drive mounting cover 12. The friction drive plate 10 is provided with a first support pillar 1004 and a second support pillar 1005, and the first support pillar 1004 and the second support pillar 1005 slide in the sliding guide rails 1204. A first compression spring 11 is provided between one end of the sliding guide rail 1204 and the first support pillar 1004, and a second compression spring 13 is provided between the other end of the sliding guide rail 1204 and the second support pillar 1005.

[0026] In the initial state, the two friction drive plates 10 are in a misaligned state in the two sliding guide rails 1204. One friction drive plate 10 is close to the rear first friction electromagnet 1202 and the rear second friction electromagnet 1203, and the other friction drive plate 10 is close to the front first friction electromagnet 1205 and the front second friction electromagnet 1206.

[0027] In this embodiment, as shown in the figure, the air flow opening and closing plate 9 includes a windward surface 903. As shown in the air flow opening and closing plate mounting hole 801, one end of the windward surface 903 is connected to the first mounting shaft 804 through a first shaft 901, the other end of the windward surface 903 is connected to the second mounting shaft 803 through a second shaft 902, the second shaft 902 is connected to a friction drive wheel 904, and the friction drive wheel 904 abuts against the friction drive plate 10.

[0028] It further includes a control component and a chip module. The chip module is arranged in the key module 2, connected to the sensor and electrically connected to a plurality of electromagnets. The control component is used to control according to the instructions of the chip module.

[0029] Working principle: In the initial state, the first adjustment electromagnet 1604, the second adjustment electromagnet 1605, the third adjustment electromagnet 1606, and the fourth adjustment electromagnet 1607 on the key housing 16 are not energized. Therefore, under the action of the air resistance adjustment spring 14, the moving bump 1503 is pushed, so that the air resistance adjustment permanent magnet 1501 contacts the first adjustment electromagnet 1604, the second adjustment electromagnet 1605, the third adjustment electromagnet 1606, and the fourth adjustment electromagnet 1607, and the air resistance adjustment plate surface 1502 closes the diversion hole 1602, making the air flow unable to pass through the key module 2. The friction drive plate 10 is divided into two left and right parts. The friction contact surface 1003 contacts the friction drive wheel 904, providing the power source for the rotation of 904. The first support column 1004 and the second support column 1005 are installed in the sliding guide rail 1204 and will respectively compress the first compression spring 11 and the second compression spring 13 installed in the sliding guide rail 1204 during the left and right sliding processes. When the air flow opening and closing plates 9 on the left and right sides are installed, when the air flow opening and closing plates 9 on both sides are closed and the air flow opening and closing plate mounting holes 801 are closed, at this time, the friction drive plate 10 is in a front and back state in the two sliding guide rails 1204, one close to the rear first friction electromagnet 1202 and the rear second friction electromagnet 1203, and the other friction drive plate 10 is close to the front first friction electromagnet 1205 and the front second friction electromagnet 1206. In the non-energized state of the keyboard, there is no magnetic force acting, and at this time, the spring will not be compressed, nor will the flow channel be completely closed and the flow channel be opened, and it will be in a semi-open state without compressing the spring.

[0030] When the computer is turned on, the keyboard is powered on. At this time, multiple micro fans 1 installed at the front end of the keyboard housing 7 operate to pump external air flow into the keyboard housing 7. And at this time, the air outlet module 6 installed at the rear end of the keyboard housing 7 is powered on, so that the rear first friction electromagnet 1202 and the front first friction electromagnet 1205 are powered on to apply an electromagnetic field. Since the first friction permanent magnets 1001 and the second friction permanent magnets 1002 are arranged at both the front and the back of the friction drive plate 10, under the action of the magnetic force and the elastic force of the compressed first compression spring 11, the friction drive plate 10 moves along the sliding guide 1204, and then drives the friction drive wheel 904 in contact with it. Since the three friction drive wheels 904 are all in close contact, the movement of the friction drive plate 10 can drive the three air flow opening and closing plates 9 to change from the closed state to the open state at the same time. When the friction drive plate 10 moves a certain distance, the second support column 1005 contacts the second compression spring 13, gradually compresses the second compression spring 13, and decelerates at the same time. When the friction drive plate 10 passes through the obstruction of the second compression spring 13 and decelerates to 0, at this time, the elastic force generated by the second compression spring 13 is greater than the magnetic force generated by the magnetic field, making the friction plate 10 become horizontal. If this state is maintained, the elastic force drives the friction drive plate 10 to oscillate reciprocally at the next moment and finally maintains balance at the position where the magnetic force and the elastic force are equal. However, this will cause the opening angles of the three air flow opening and closing plates 9 to also shake, which is not conducive to the stable air outlet of the keyboard. Therefore, when the friction drive plate 10 decelerates to 0, at the next moment, the rear second friction electromagnet 1203 and the front second friction electromagnet 1206 are powered on to enhance the magnetic force, so that the magnetic forces generated by the two magnetic fields are the same or similar to the elastic force at this time, and then the friction drive plate 10 is kept stable at this place to prevent the reciprocating shaking of the friction drive plate 10 from causing the air outlet module 6 to open and close reciprocally. It should be noted here that the energizing directions of the electromagnets corresponding to the two friction plates 10 are opposite.

[0031] When the experimenter presses a certain key module 2, the sliding bracket 1601 slides downward along the key bracket 4, and at the same time, the return spring 3 installed between the bottom surface of the keyboard housing 7 and the sliding bracket 1601 is compressed. After the pressure sensor (not marked in the figure) installed at the lower part of the return spring 3 senses the pressure change, it converts it into an electrical signal and transmits it to the built-in chip of the keyboard (not marked in the figure). After the built-in chip (not marked in the figure) detects the specific key module 2 touched by the experimenter, it first cuts off the power supply of the rear second friction electromagnet 1203 and the front second friction electromagnet 1206, and at the same time, the power supply directions of the rear first friction electromagnet 1202 and the front first friction electromagnet 1205 are opposite, so that the six air flow opening and closing plates 9 of the air outlet module 6 change from the open state to the closed state by 90°. After reverse power supply, at the point where the speed is 0, the rear second friction electromagnet 1203 and the front second friction electromagnet 1206 are powered on, and then the balance of the air outlet module 6 is maintained. And because the two friction drive plates 10 move in opposite directions, the momentum and impact cancel each other out, so that the stability of the keyboard is enhanced and it will not shake randomly. Subsequently, the electromagnets of the six key modules around the pressed key module 2 are powered on. Since the distances of the six key modules from the micro fan 1 are different, the air flow resistance when the air flow enters different key modules 2 is also different. For the key module closest to the micro fan 1, only the first adjustment electromagnet 1604 is powered on to generate a magnetic field, so that the air resistance adjustment permanent magnet 1501 is driven by the magnetic force and moves to the right to compress the air resistance adjustment spring 14, and then a part of the diversion hole 1602 is opened. However, since the opening amplitude is not large, the air resistance of this key module is the highest. For the two key modules 2 in the second echelon, in addition to the first adjustment electromagnet 1604 being powered on, the second adjustment electromagnet 1605 is also powered on. By enhancing the magnetic field, the corresponding magnetic force is increased, and then the air resistance adjustment plate 15 can be further pushed to move away from the electromagnet, so that the diversion hole 1602 is further opened. Similarly, for the two key modules 2 in the third echelon, in addition to the above two electromagnets being powered on, the third adjustment electromagnet 1606 is also powered on, and then the diversion hole 1602 is further opened. Finally, for the one key module 2 in the fourth echelon, all four electromagnets are powered on, so that the diversion hole 1602 is opened to the maximum extent. Since the magnetic force becomes weaker as the air resistance adjustment permanent magnet 1501 is farther away from the electromagnet, and the higher the degree of spring compression, the greater the reverse elastic force, the first adjustment electromagnet 1604, the second adjustment electromagnet 1605, the third adjustment electromagnet 1606 and the fourth adjustment electromagnet 1607 are not of the same size, and the magnetic fields they generate gradually increase. Therefore, when the six key modules around the pressed key module 2 (pressing the S key) are accidentally touched, an approximately same damping can be generated to prompt the researchers that two keys are pressed simultaneously, preventing errors in experimental records.When the key module 2 is released, the electromagnets of the six surrounding key modules are all powered off, enabling the air resistance adjustment spring 14 to release its elastic force and close all the diversion holes 1602. At the same time, the rear second friction electromagnet 1203 and the front second friction electromagnet 1206 are powered off first, and the power supply directions of the rear first friction electromagnet 1202 and the front first friction electromagnet 1205 are opposite, causing the six air flow opening and closing plates 9 of the air outlet module 6 to change from the closed state to the open state by 90°. After reverse power supply, at the point where the speed is 0, the rear second friction electromagnet 1203 and the front second friction electromagnet 1206 are powered on, and then the air outlet module 6 is kept balanced. This is a working cycle of the keyboard. Here it is noted that only one friction electromagnet (such as key A) is turned on, two friction electromagnets (such as keys W and Z) are turned on, three friction electromagnets (such as keys E and X) are turned on, and four electric friction electromagnets (such as pressing key D).

[0032] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art of this technology, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
