Description

Technical Field

[0001] The utility model is applied to the technical field of keyboards, and particularly relates to a simple magnetic axle keyboard without a fixed plate. Background Art

[0002] With the innovation and development of science and technology, in order to reduce the burden on the hands and wrists of office workers and e-sports players, new magnetic axle keyboard products have emerged as the times require. Such novel magnetic axle keyboards use the induction cooperation between magnets and Hall sensors to make the pressing feedback more accurate, and the speed of the pressing feedback can be adjusted according to personal habits, allowing users to have a good hand feel experience of a magnetic axle multi-stage trigger keyboard, which enables office workers and game competitors to maintain good working efficiency and game feel at all times. At present, the magnetic axles on the magnetic axle keyboards available in the market are generally fixed on the upper cover or the fixed plate, while the Hall IC matched with the magnetic axles and other electronic components are placed on a PCBA, and then connected with the upper cover or the fixed plate through screw posts or other fixing methods. Besides, traditional magnetic axles arrange the magnet at the lower end of the axle core, and the magnet is induced and matched with the Hall sensor on the PCBA by pressing the axle core downward. This arrangement requires the bottom of the magnetic axle housing to be connected with the upper end surface of the PCBA. Since the magnetic axle housing has a certain height as a whole, the overall height of such magnetic axle keyboards is relatively high, and operators are prone to soreness and other symptoms in their wrists after long-term use, which affects the long-term use experience of operators. Moreover, in pursuit of noise reduction effect, silencing cotton, gasket and other parts are placed between the fixed plate and the PCBA, and silencing cotton, silica gel and other parts are placed between the PCBA and the lower cover supporting the PCBA. This leads to complex structure, cumbersome assembly and high cost. If a simple fixed-plate-free magnetic axle keyboard with simple structure, which eliminates the traditional upper cover or fixed plate fixed on the magnetic axles and sound-insulating cotton, and is thinner and lighter as a whole, can be designed, the above problems can be solved. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art, and provide a simple fixed-plate-free magnetic axle keyboard which has a simple structure, eliminates the traditional upper cover or fixed plate fixed on the magnetic axles and sound-insulating cotton, and is thinner and lighter as a whole.

[0005] Furthermore, the noise reduction and buffer module includes noise reduction cotton and buffer pads, which are arranged sequentially from top to bottom on the upper end of the bottom cover, and the lower end face of the PCBA board cooperates with the noise reduction cotton.

[0006] Furthermore, the sound insulation cotton is provided with a number of clearance grooves, and the clearance grooves cooperate with the bottom of the magnetic shafts at corresponding positions.

[0007] Furthermore, the magnetic shaft includes an upper housing, a lower housing, and a shaft core. The lower housing is connected to one side of the lower end face of the upper housing. The shaft core is disposed between the upper housing and the lower housing. The keycap is connected to the upper end of the shaft core through the opening end of the upper housing. A pressing extension block is provided on one side of the middle portion of the shaft core, and a sensing magnet is provided on the pressing extension block. A sensing port is provided on the other side of the lower end face of the upper housing. The shaft core drives the sensing magnet to sense and cooperate with the sensor module on the PCBA board through the sensing port.

[0008] Furthermore, the sensor module includes a Hall sensor and an RGB lamp mounted on an IC chip, and several IC chips are mounted on the lower end of the PCBA board. The Hall sensor is magnetically coupled with the magnetic shaft.

Detailed Implementation

[0016] like Figures 1 to 7 As shown, in this embodiment, the present invention includes a bottom cover 1, a PCBA board 2, and several button modules 3. The PCBA board 2 is disposed on the upper end of the bottom cover 1. The several button modules 3 include keycaps 31 and magnetic shafts 32. The several magnetic shafts 32 are connected to corresponding connecting ends of the PCBA board 2. A noise-absorbing buffer module 4 is disposed between the PCBA board 2 and the bottom cover 1. The PCBA board 2 is provided with several sensor modules 5. When the keycaps 31 are subjected to force, they drive the magnetic shafts 32 to cooperate with the corresponding sensor modules 5. It can be seen that the several button modules 3 directly connect to the PCBA board 2, taking materials from the upper cover assembly and sound insulation cotton of the PCBA board 2, making the overall PCBA board 2 simpler, further reducing weight, and improving assembly efficiency.

[0017] like Figure 2As shown, in this embodiment, the noise-absorbing buffer module 4 includes noise-absorbing cotton 41 and buffer pad 42. The noise-absorbing cotton 41 and the buffer pad 42 are arranged sequentially from top to bottom on the upper end of the bottom cover 1, and the lower end face of the PCBA board 2 cooperates with the noise-absorbing cotton 41. Therefore, the noise-absorbing cotton 41 and the buffer pad 42 can effectively play the role of pressure buffering and noise reduction.

[0018] like Figure 2 As shown, in this embodiment, the sound-absorbing cotton 41 is provided with a plurality of clearance grooves 43, which cooperate with the bottom of a plurality of magnetic shafts 32 at corresponding positions. Therefore, the clearance grooves 43 can avoid obstructing the movement of the plurality of key modules 3, making the keyboard thinner and preventing the sound-absorbing cotton 41 from shifting.

[0019] like Figure 3 , Figure 6 as well as Figure 7 As shown, in this embodiment, the magnetic shaft 32 includes an upper housing 321, a lower housing 322, and a shaft core 323. The lower housing 322 is connected to one side of the lower end face of the upper housing 321. The shaft core 323 is disposed between the upper housing 321 and the lower housing 322. The keycap 31 is connected to the upper end of the shaft core 323 through the opening end of the upper housing 321. A pressing extension block 324 is provided on one side of the middle part of the shaft core 323. The pressing extension block 324 is provided with a sensing magnet 325. A sensing port 326 is provided on the other side of the lower end face of the upper housing 321. The shaft core 323 drives the sensing magnet 325 to sense and cooperate with the sensor module 5 on the PCBA board 2 through the sensing port 326. Therefore, the upper and lower housing structures of the magnetic axis 32, with the upper housing 321 and the lower housing 322 forming a core pressing channel, can trigger the pressing stroke. The upper housing 321 is provided with a lifting space for the extension block. Compared to the method of setting it at the bottom of the core, the pressing extension block 324 is set in the middle of the core 323, which can reduce the overall height of the keyboard axis. The housing 322 can be embedded in the PCBA board 2 instead of being set at the top of the PCBA board 2. The key height can be reduced without affecting the cooperation of the sensing magnet 325 with the sensor module 5, making the keyboard flatter and more convenient to store or carry.

[0020] like Figure 3 As shown, in this embodiment, the sensor module 5 includes a Hall sensor 51 and an RGB light 52 mounted on an IC chip. Several IC chips are disposed at the lower end of the PCBA board 2. The Hall sensor 51 magnetically engages with the magnetic shaft 32. Therefore, by using a dedicated IC 5505 with a matching new magnetic shaft and integrating the RGB light onto the Hall sensor module, the overall keyboard space is utilized more efficiently, resulting in a thinner and lighter design.

[0021] like Figure 2 As shown, in this embodiment, the upper end of the PCBA board 2 is provided with a plurality of satellite axes 6, which cooperate with the keycaps 31 and the magnetic axis 32 at corresponding positions. Therefore, for larger keys, the satellite axes 6, in conjunction with the magnetic axis 32, achieve a balanced pressing effect.

[0022] like Figure 1 and Figure 2 As shown, in this embodiment, a pad 7 is provided on the upper surface of the PCBA board 2. A plurality of magnetic shafts 32 are connected to the PCBA board 2 via the pad 7, and the pad 7 conforms to the opening of the bottom cover 1. Therefore, the pad 7 can protect the PCBA board 2 and provide dust protection. The outer edge of the pad 7 conforms to the upper end of the bottom cover 1, effectively preventing dust from entering the interior of the bottom cover 1.

[0023] like Figure 4 As shown, in this embodiment, a plurality of support columns 8 are provided on the inner bottom of the bottom cover 1. The plurality of support columns 8 pass through the sound-absorbing cotton 41 and the buffer pad 42 and cooperate with the support position on the lower end face of the PCBA board 2. It can be seen that the plurality of support columns 8 can be made into the PCBA board 2 and can fix the PCBA board 2 on the bottom cover 1.

[0024] like Figure 5 As shown, in this embodiment, the bottom of the buffer pad 42 is provided with several contoured grooves 44, which cooperate with several supporting reinforcing ribs 9 and several supporting columns 8 on the inner side of the bottom cover 1. Therefore, the contoured grooves 44 allow the buffer pad 42 to be more stably fixed to the inner side of the bottom cover 1, making it less prone to displacement or deformation during use.

[0025] like Figure 4 As shown, in this embodiment, a wire insertion groove 10 is provided on the rear side of the bottom cover 1, and the interface end of the PCBA board 2 is connected to the external power module through the wire insertion groove 10. Therefore, the external power supply is connected to the PCBA board 2 through the wire insertion groove 10 to provide power.

[0026] The working principle of this utility model is as follows: First, several magnetic axes 32, several satellite axes 6, and the pad 7 are assembled onto the upper surface of the PCBA board 2 to form a whole. Then, the buffer pad 42 and the sound-absorbing cotton 41 are placed sequentially on the upper end of the bottom cover 1. The PCBA board 2 is placed on the bottom cover 1 and fixed to the bottom plate 1 with screws using several support columns 8. At this point, the entire keyboard is completed and can be directly connected to the PCBA board 2 for power supply through the wire insertion groove 10.

[0027] Although the embodiments of this utility model are described with reference to actual solutions, they do not constitute a limitation on the meaning of this utility model. For those skilled in the art, modifications to the implementation schemes and combinations with other schemes based on this specification are obvious.
