Description

Technical Field

[0001] The invention relates to the field of keyboard structures, and in particular to a key structure and a wireless keyboard capable of self-generating and self-supplying power. Background Art

[0002] Traditional keyboards require wired connections, and their use and installation are limited by the connection wires, which also makes the desktop very messy. Nowadays, the popularity of electronic products, especially computers, has led to an increasing use of wireless keyboards. Wireless keyboards are generally connected to computers via wireless Bluetooth, which can break through these limitations of traditional keyboards. Since wireless keyboards are not electrically connected to computers for charging, wireless input keyboards require battery power. At present, most wireless keyboards on the market use disposable batteries to provide energy, which has low battery life. Once the battery is exhausted, the device will not be able to operate normally and needs to be replaced, which greatly increases the cost of use for consumers. If you are working away from home and the battery power of the wireless keyboard is insufficient, the wireless keyboard will not be able to be used. If you use text editing software, the use of the keyboard without a keyboard will increase the difficulty of operation. In this case, most manufacturers will delete some functions and effects of the keyboard for battery life considerations, which will lose some advantages compared to traditional keyboards and restrict the promotion and use of wireless keyboards. In addition, after the power of the wireless keyboard is used up, some wireless keyboards have batteries installed tightly, which is difficult to replace, and nails are often damaged. Finally, if the battery is not effectively handled after replacement, it will also cause more serious environmental pollution. Summary of the invention

[0003] Purpose of the invention: In view of the problems existing in the prior art, the present invention provides a key structure and a wireless keyboard with self-generated and self-powered power, which utilize the mechanical movement of the keyboard to achieve self-generated power, solve the problem of wireless keyboard battery replacement and the keyboard being unable to be used due to lack of power, save energy, be green and environmentally friendly, and be easy to use.

[0004] Technical solution: The present invention provides a button structure with self-generated electricity and self-powered supply, including a finger pressure block, a touch plate, a bearing, a magnetic rotor assembly, a coil assembly, a spring and a base, wherein the finger pressure block is fixed on the touch plate, the bearing is coaxially arranged in the middle of the touch plate, and the magnetic rotor assembly is rotatably connected to the touch plate through the bearing; the spring is sleeved on the outside of the rotor of the magnetic rotor assembly, the top end of which is fixedly connected to the touch plate, and the bottom end is fixedly connected to the base; the coil in the coil assembly is arranged perpendicular to the rotation direction of the rotor, and the two ends of the coil in the coil assembly are respectively connected to the input end and the output end of the rectifier.

[0005] Furthermore, the magnetic rotor assembly includes a rotor and at least one moving conductor, the middle part of the base is a hollow cavity, and the side walls of the hollow cavity have spiral track grooves that are equal in number to the moving conductors and are arranged parallel to each other; the top outer wall of the rotor is fixedly connected to the inner ring of the bearing, and the outer ring of the bearing is fixedly connected to the inner wall of the bearing interface in the middle of the contact plate; the outer side of the bottom of the rotor is rotatably connected to the moving conductor, the moving conductor is stuck in the track groove and the bottom of the rotor is located in the hollow cavity of the base. The finger pressure block is pressed, and the finger pressure block drives the touch plate to move downward. The downward movement of the touch plate compresses the spring and drives the rotor to move downward. The downward movement of the rotor forces the moving conductor to rotate and move downward along the track groove of the base, thereby rotating and moving the rotor downward. When the pressure applied to the finger pressure block disappears, the spring rebounds and drives the touch plate to move upward, thereby moving the rotor upward. The moving conductor rotates and moves upward along the track groove, thereby rotating and moving the rotor upward. In the process of the above-mentioned rotor moving upward or downward, the rapid rotation of the N pole and S pole of the rotor will cut the magnetic induction line in the coil assembly, causing current to be generated in the coil, and then the current is output to the storage device through the rectifier to realize power supply for the key.

[0006] Preferably, there are two moving conductors and two track grooves; the two moving conductors are symmetrically arranged at the lower outer side of the rotor, and the two moving conductors are respectively stuck in the two track grooves. The arrangement of two moving conductors is conducive to the movement balance of the magnetic rotor assembly.

[0007] Furthermore, the coil assembly includes a coil and a coil bracket, the coil bracket is sleeved on the outside of the spring and the top is fixedly connected to the contact plate, the coil is wound on the coil bracket, and the winding direction of the coil is perpendicular to the rotation plane of the rotor. When an external force presses the finger pressure block, the contact plate moves downward, which will drive the coil bracket and the coil thereon to move downward together, and the rotor rotates while moving downward as the contact plate moves downward, so that the position between the rotor and the coil remains unchanged, and the rotor only rotates relative to the coil. The winding direction of the coil is perpendicular to the rotation plane of the rotor, which can ensure that when the rotor rotates, its rapidly rotating N pole and S pole can effectively cut the movement of the magnetic induction line.

[0008] Preferably, the contact plate, the bearing, the bearing interface, the base, the track groove, the coil and the coil support are all coaxially arranged. The coaxial arrangement of the above components can effectively ensure that the rotor performs a vertical downward rotational movement and ensures that the rotor can effectively cut the magnetic induction line movement.

[0009] Preferably, the bearing interface and the outer ring of the bearing are interference fit.

[0010] Preferably, the inner ring of the bearing and the rotor are in interference fit.

[0011] Preferably, there is a clearance fit between the track groove and the moving conductor.

[0012] Preferably, the rotor is a permanent magnetic rotor.

[0013] The present invention also provides a wireless keyboard, comprising the above-mentioned key structure with self-generated and self-powered power.

[0014] Beneficial effects: When the self-generating and self-powering button structure of the present invention is working, the finger pressure block is pressed, and the finger pressure block presses down the touch plate. The touch plate drives the magnetic rotor assembly to move downward while compressing the spring. The rotor in the magnetic rotor assembly rotates in the coil of the coil assembly, and cuts the magnetic flux lines while rotating; when the finger pressure block is released, the spring rebounds, and the touch plate and the magnetic rotor assembly are moved upward together, and the magnetic rotor assembly also rotates and cuts the magnetic flux lines while moving upward, and the upward movement of the touch plate drives the finger pressure block to move upward, and the finger pressure block is reset; in the process of the magnetic rotor assembly moving downward and rotating upward, the rapid rotation of the N pole and S pole of the rotor will cut the magnetic flux lines to generate current in the coil, and the current is output to the rectifier, and then output to the storage device through the rectifier to realize power supply for the button.

[0015] It can be seen that this keyboard can generate current in the coil when the finger pressure block is pressed or released, so that the key structure can generate electricity and power itself; the mechanical movement of the keyboard is used to achieve autonomous power generation and power supply, which solves the problem of replacing batteries for wireless keyboards and the problem of the keyboard being unable to be used due to lack of power, saves energy, is green and environmentally friendly, and is easy to use.

[0032] The present invention is described in detail below in conjunction with the accompanying drawings.

The spring 6 is sleeved on the outside of the rotor 401, and its top end is fixedly connected to the contact plate 2, and its bottom end is fixedly connected to the base 7. The coil assembly 5 is mainly composed of a coil 501 and a coil support 502. The coil support 502 is sleeved on the outside of the spring 6 and its top is fixedly connected to the contact plate 2. The coil 501 is wound on the coil support 502, and the winding direction of the coil 501 is perpendicular to the rotation plane of the rotor 401. The above-mentioned contact plate 2, bearing 3, bearing interface 201, base 7, track groove 701, coil 501 and coil support 502 are all coaxially arranged. The above-mentioned bearing 3 preferably uses an angular contact ball bearing or a tapered roller bearing.

[0035] The working principle of the self-generating and self-powering key structure of the present invention is as follows:

[0036] During operation, the finger pressing block 1 is pressed, and the finger pressing block 1 presses the contact plate 2 downward, and the contact plate 2 moves downward to compress the spring 6 and drive the rotor 401 downward. At the same time, the downward movement of the contact plate 2 will also drive the coil 501 and the coil support 502 downward; the downward movement of the rotor 401 forces the moving conductor 402 to rotate and move downward along the track groove 701 of the base 7, so that the rotor 401 rotates and moves downward; when the pressure applied to the finger pressing block 1 disappears, the spring 6 rebounds and drives the contact plate 2 to move upward, so that the rotor 401 and the coil 501 and the coil support 502 are The coil bracket 502 moves upward, and the moving conductor 402 rotates and moves upward along the track groove 701, so that the rotor 401 rotates and moves upward; the touch plate 2 and the finger pressure block 1 move upward and reset; in the process of the above-mentioned rotor 401 moving up or down, the N pole and S pole of the rotor 401 rotate rapidly to cut the magnetic induction line in the coil 501, causing the coil 501 to generate current, and then the current is output to the power storage device such as a rechargeable battery through the rectifier to realize power supply to the key, collect electrical energy, and provide electrical energy for the key.

[0037] In practical applications, a keyboard can be assembled from a plurality of the above-mentioned keys, and lubricants such as graphite are added as much as possible between the rotor 401 and the bearing interface 201; lubricants such as graphite are used as much as possible between the moving conductor 402 at the bottom of the rotor 401 and the track groove 701 of the base 7.

[0038] Implementation 2:

[0039] This embodiment is a further improvement of the embodiment 1. The main improvement is that in the embodiment 1, in the rotor assembly 4, only one side of the lower part of the rotor 401 has the moving conductor 402. When the rotor 401 moves downward and drives the moving conductor 402 to move downward along the track groove 701, the rotor 401 may be offset. Therefore, in this embodiment, a moving conductor 402 is respectively arranged at the symmetrical positions on both sides of the lower part of the rotor 401, such as Figures 13-16 Accordingly, two mutually parallel track grooves 701 are designed on the base 7, and the two moving conductors 402 are respectively stuck in the two track grooves 701. In this way, when the rotor moves downward, the moving conductors 402 on both sides move downward along the two track grooves 701 respectively. Since the two moving conductors 402 are symmetrically arranged on both sides of the rotor 401, the downward movement of the rotor 401 is relatively stable.

Any equivalent transformation or modification made according to the spirit of the present invention should be included in the protection scope of the present invention.
