Description

Technical Field

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

[0002] At present, many high-precision experimental studies at home and abroad need to be carried out at a certain temperature. For example, atomic layer deposition technology in the semiconductor field requires the growth of coatings on wafers. However, in the laboratory or industrial production process, process engineers need to frequently adjust experimental parameters to obtain the optimal production process. Therefore, they need to use heat-insulating gloves relatively frequently to open and close high-temperature equipment, replace experimental items in it, and record experimental data on the computer. Frequent removal and wearing of heat-insulating equipment will make researchers feel irritated. However, existing anti-accidental touch industrial keyboards achieve the effect of preventing accidental touch by creating a certain degree of damping on the keycaps through airflow impacting the keycaps. However, due to the dense flow channels inside the keyboard, the energy of the airflow will dissipate too quickly during the propagation of the keyboard, resulting in excessive damping of the keycaps on the side close to the micro-blower, while the damping of the keycaps on the side away from the micro-blower is too small. The large damping difference between the two sides of the keyboard will affect the operating comfort and judgment accuracy of researchers. Summary of the Invention

[0040] like Figures 1-10 As shown, an industrial keyboard suitable for high temperature operation is disclosed, comprising:

[0041] A keyboard housing 7, wherein one end of the keyboard housing 7 is provided with a micro fan 1 and the other end is provided with an air outlet module 6. The top of the keyboard housing 7 is elastically connected to the key module 2 via a key bracket 4, and one end of the top is provided with a trackball 5;

[0042] like Figure 4 and Figure 9 As shown, the button module 2 is provided with a sensor and a sliding bracket 1601 connected to the button bracket 4. The side of the button module 2 is provided with a guide hole 1602, and the guide hole 1602 is magnetically connected to the wind resistance adjustment plate 15;

[0043] When the button module 2 is pressed, the air outlet module 6 is closed, the electromagnetic is energized, and the wind resistance adjustment plate 15 is opened to reduce the damping of the button module.

[0044] like Figure 7 and Figure 9As shown, in the specific implementation process of this embodiment, one side of the guide hole 1602 is provided with a first adjusting electromagnet 1604, a second adjusting electromagnet 1605, a third adjusting electromagnet 1606, and a fourth adjusting electromagnet 1607 from top to bottom, and the other side is provided with a wind resistance adjusting sliding groove 1603, and a wind resistance adjusting spring 14 is provided in the wind resistance adjusting sliding groove 1603. One side of the wind resistance adjusting plate 15 is provided with a wind resistance adjusting permanent magnet 1501, and the other side is provided with a movable protrusion 1503 equipped with the wind resistance adjusting sliding groove 1603. According to the distance between the button module 2 and the micro fan 1, the opening size of the wind resistance adjusting plate 15 is realized by energizing multiple electromagnets.

[0045] Initially, the first adjustment electromagnet 1604, the second adjustment electromagnet 1605, the third adjustment electromagnet 1606 and the fourth adjustment electromagnet 1607 on the button shell 16 are not energized. Therefore, under the action of the wind resistance adjustment spring 14, the movable protrusion 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 guide hole 1602, so that the airflow cannot pass through the button module 2.

[0046] like Figure 1 As shown, in the specific implementation process of this embodiment, a return spring 3 is sleeved between the button bracket 4 and the sliding bracket 1601, and the button module 2 can automatically reset when it is pressed.

[0047] like Figure 2-Figure 3 、 Figure 5 As shown, in the specific implementation process of this embodiment, the air outlet module 6 includes an air outlet bracket 8, and air flow opening and closing plates 9 are provided on both sides of the air outlet bracket 8. The air flow opening and closing plates 9 are connected to a driving mechanism, and the driving mechanism is provided in the middle of the air outlet bracket 8.

[0048] further, Figure 8As shown, the driving mechanism includes a friction drive mounting cover 12, and the bottom of the friction drive mounting cover 12 is magnetically connected to a friction drive plate 10 for driving the airflow opening and closing plate 9. The friction drive plate 10 is divided into two parts, left and right. One end of the friction drive plate 10 is provided with a first friction permanent magnet 1001, and the other end is provided with a second friction permanent magnet 1003. The top is slidingly connected to the friction drive mounting cover 12. One end of the friction drive mounting cover 12 in the cavity 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 power is turned on, the front first friction electromagnet 1205 and the first friction permanent magnet 1001 generate opposite magnetic fields, and the second friction permanent magnet 1003 and the rear first friction electromagnet 1202 attract each other, driving the friction drive plate 10 to drive the airflow opening and closing plate 9 to open.

[0049] When the airflow opening and closing plates 9 on both sides are closed and the airflow opening and closing plate mounting holes 801 are closed, the friction drive plate 10 is in a front-and-rear position in the two sliding guide rails 1204.

[0050] In this embodiment, a sliding guide rail 1204 is provided at the bottom of the friction drive mounting cover 12, and the friction drive plate 10 is provided with a first support 1004 and a second support 1005. The first support 1004 and the second support 1005 slide within the sliding guide rail 1204. A first compression spring 11 is provided between one end of the sliding guide rail 1204 and the first support 1004, and a second compression spring 13 is provided between the other end of the sliding guide rail 1204 and the second support 1005.

[0051] In the initial state, the two friction drive plates 10 are in a staggered 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.

[0052] In this embodiment, as shown in the figure, the airflow opening and closing plate 9 includes a windshield surface 903, which is arranged in the airflow opening and closing plate mounting hole 801. One end of the windshield surface 903 is connected to the first mounting shaft 804 through the first shaft 901, and the other end of the windshield surface 903 is connected to the second mounting shaft 803 through the second shaft 902. The second shaft 902 is connected to the friction drive wheel 904, and the friction drive wheel 904 is in contact with the friction drive plate 10.

[0053] It also includes a control component and a chip module. The chip module is arranged in the key module 2 and is connected to the sensor and electrically connected to multiple electromagnets. The control component is used to control according to the instructions of the chip module.

[0054] Working principle:

[0055] Initially, the first, second, third, and fourth adjustment electromagnets 1604, 1605, 1606, and 1607 on the key housing 16 are de-energized. Consequently, the windage adjustment spring 14 pushes the movable protrusion 1503, causing the windage adjustment permanent magnet 1501 to contact the first, second, third, and fourth adjustment electromagnets 1604, 1605, 1606, and 1607. Furthermore, the windage adjustment plate 1502 closes the air guide holes 1602, preventing airflow from passing through the key module 2. The friction drive plate 10 is divided into two left and right sections. The friction contact surface 1003 contacts the friction drive wheel 904, providing power for its rotation. The first and second struts 1004, 1005, are mounted within the sliding guide rail 1204. During left and right sliding, they compress the first and second compression springs 11, 13, respectively, mounted within the sliding guide rail 1204. When the left and right airflow opening and closing plates 9 are installed, and therefore when both are closed, closing the airflow opening and closing plate mounting holes 801, the friction drive plates 10 are positioned one in front of the other within the two sliding guide rails 1204, one near the rear first friction electromagnet 1202 and rear second friction electromagnet 1203, and the other near the front first friction electromagnet 1205 and front second friction electromagnet 1206. When the keyboard is not powered on and there is no magnetic force acting, the spring is not compressed, and the flow channel is neither fully closed nor fully opened. Instead, the plate is in a semi-open state with no spring compression.

[0056] When the computer is turned on, the keyboard is powered on. At this time, the multiple micro fans 1 installed at the front end of the keyboard housing 7 are in operation to pump external air into the keyboard housing 7, and the air outlet module 6 installed at the rear end of the keyboard housing 7 is powered on, so that the first friction electromagnet 1202 at the rear and the first friction electromagnet 1205 at the front are powered on to apply an electromagnetic field. Since the friction drive plate 10 is provided with the first friction permanent magnet 1001 and the second friction permanent magnet 1002 at the front and back, the friction drive plate 10 moves along the sliding guide rail 1204 under the action of the magnetic force and the elastic force of the compressed first compression spring 11, thereby driving the friction drive wheel 904 in contact with it. Since the three friction drive wheels 904 are in close contact, the movement of the friction drive plate 10 can simultaneously drive the three airflow opening and closing plates 9 from a closed state to an open state. After the friction drive plate 10 has moved a certain distance, the second support 1005 contacts the second compression spring 13, gradually compressing the second compression spring 13 and simultaneously decelerating. When the friction drive plate 10 passes the second compression spring 13 and decelerates to zero, the elastic force generated by the second compression spring 13 is greater than the magnetic force generated by the magnetic field, causing the friction plate 10 to return to a horizontal position. If this position is maintained, the elastic force will next drive the friction drive plate 10 to oscillate back and forth, eventually reaching equilibrium at a point where the magnetic force and the elastic force are equal. However, this will cause the opening angles of the three airflow opening and closing plates 9 to fluctuate, which is detrimental to the stable air flow of the keyboard. Therefore, when the friction drive plate 10 decelerates to zero, the second friction electromagnet 1203 at the rear and the second friction electromagnet 1206 at the front are energized, increasing the magnetic force so that the magnetic forces generated by the two magnetic fields are equal to or similar to the elastic force at this point, thereby maintaining the friction drive plate 10 in this position and preventing the reciprocating oscillation 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.

[0057] When the experimenter presses a key module 2, the sliding bracket 1601 slides downward along the key bracket 4 and compresses the return spring 3 installed between the bottom surface of the keyboard housing 7 and the sliding bracket 1601. A pressure sensor (not marked in the figure) is installed at the bottom of the return spring 3. After sensing the pressure change, it converts it into an electrical signal and transmits it to the keyboard built-in chip (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 moves the rear second friction electromagnet 1203 and the front second friction electromagnet 12 06 is powered off, and at the same time, the power directions of the first friction electromagnet 1202 at the rear and the first friction electromagnet 1205 at the front are reversed, so that the six airflow opening and closing plates 9 of the air outlet module 6 are changed from the open state to the closed state by 90°. After the power is reversed, at the point where the speed is 0, the second friction electromagnet 1203 at the rear and the second friction electromagnet 1206 at the front are energized, and then the balance of the air outlet module 6 is maintained. Since the two friction drive plates 10 move in opposite directions, the momentum and impact cancel each other out, which enhances the stability of the keyboard and prevents it from shaking at will. Then, the electromagnets of the six button modules around the pressed button module 2 are energized. Since the six button modules are at different distances from the micro fan 1, the airflow resistance when the airflow enters different button modules 2 is also different. For the button module closest to the micro fan 1, only the first adjustment electromagnet 1604 is energized to generate a magnetic field, so that the wind resistance adjustment permanent magnet 1501 is driven by magnetic force and moves to the right to compress the wind resistance adjustment spring 14, thereby partially opening the guide hole 1602. However, since the opening range is not large, the wind resistance of this button module is the highest. In the two button modules 2 of the second echelon, in addition to energizing the first adjustment electromagnet 1604, the second adjustment electromagnet 1605 is also energized. By strengthening the magnetic field, the corresponding magnetic force is increased, which can further push the wind resistance adjustment plate 15 away from the electromagnet, so that the diversion hole 1602 is further opened. Similarly, in the two button modules 2 of the third echelon, in addition to energizing the above two electromagnets, the third adjustment electromagnet 1606 is also energized, thereby further opening the diversion hole 1602. Finally, in the button module 2 of the fourth echelon, all four electromagnets are energized, so that the diversion hole 1602 is opened to the maximum extent. As the wind resistance adjustment permanent magnet 1501 moves farther away from the electromagnet, the magnetic force becomes weaker, and the higher the spring compression degree, the greater the reverse elastic force. Therefore, 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 pressed key module 2 (press the S key) is accidentally touched, the six key modules surrounding it can generate approximately the same damping, prompting researchers that they have pressed two keys at the same time, thereby preventing errors in experimental records.When the key module 2 is released, the electromagnets of the six surrounding key modules are all powered off, so that the wind resistance adjustment spring 14 releases the elastic force and all the guide holes 1602 are closed. At the same time, the second friction electromagnet 1203 at the rear and the second friction electromagnet 1206 at the front are powered off first, and the power directions of the first friction electromagnet 1202 at the rear and the first friction electromagnet 1205 at the front are reversed, so that the six airflow opening and closing plates 9 of the air outlet module 6 are changed from the closed state to the open state by 90°. After reverse power is applied, at the point where the speed is 0, the second friction electromagnet 1203 at the rear and the second friction electromagnet 1206 at the front are energized, and then the air outlet module 6 is kept balanced. This is a working cycle of the keyboard. It is explained here that only one friction electromagnet is turned on (for example, key A), two friction electromagnets are turned on (for example, key W and key Z), three friction electromagnets are turned on (for example, key E and key X), and four electric friction magnets are turned on (for example, pressing key D).

[0058] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
