Description

Technical Field

[0001] The utility model relates to the technical field of keyboards, in particular to a carbon fiber keyboard. Background Art

[0002] A mechanical keyboard includes an outer shell, an inner shell and keycaps. The outer shell at least includes a base. The inner shell at least includes a positioning plate, a circuit board and a key shaft switch. A plurality of key shaft switches are inserted behind the positioning plate. The pins of the key shaft switches are electrically connected to the circuit board. The keycaps are detachably and replaceably installed on the cross shafts of the corresponding key shaft switches. An existing mechanical keyboard uses carbon fiber material to make the base and the positioning plate, and the base and the positioning plate form a box-shaped outer shell. In addition, since the interior of the base made of carbon fiber material cannot be formed into a structure connected to the inner shell, it is necessary to add an internal connection seat that provides a connection structure and is adhered to the inner wall surface of the base.

[0003] The base made of carbon fiber material is also unable to form a complex hinge and spring connection structure, and cannot be provided with swinging feet for adjusting the height. Therefore, the bottom surface of the base of the existing carbon fiber mechanical keyboard is simply glued with four rubber blocks as feet, and the feet are not adjustable, and cannot bring a better user experience. Utility Model Content

[0004] The main purpose of the utility model is to provide a carbon fiber keyboard which is height-adjustable by setting a replaceable and detachable height-increasing structure by means of magnetic attraction.

[0005] The carbon fiber keyboard provided by the utility model comprises an outer shell, an inner shell and key caps, the outer shell comprises a base and an inner connecting seat, the base is made of carbon fiber material, the inner connecting seat is fixed in the base, a cushion block is adhered to the bottom surface of the base, the inner shell comprises a circuit board, a fixing plate and a key shaft switch, the key shaft switch is inserted on the fixing plate and electrically connected to the circuit board, and the key cap is connected to the key shaft switch; the carbon fiber keyboard also comprises at least two groups of height-increasing structures that can be optionally installed, the height-increasing structure comprises a height-increasing body and a first magnetic attraction component, and there is a height difference between the height-increasing bodies of different groups of height-increasing structures, the top of the height-increasing body is provided with an avoidance groove opening upward and a first mounting groove, and the first magnetic attraction component is arranged in the first mounting groove; the carbon fiber keyboard also comprises a second magnetic attraction component, a second mounting groove is provided on the inner connecting seat, and the second magnetic attraction component is arranged in the second mounting groove; any group of height-increasing structures can be selectively and detachably installed outside the base and supported below the bottom surface, the cushion block is located in the avoidance groove, and the first magnetic attraction component is opposite to and attracted to the second magnetic attraction component.

[0006] It can be seen from the above scheme that the utility model maintains a means of sticking a pad on the bottom surface of the carbon fiber base, and provides users with at least two groups of height-increasing structures of different heights that can be optionally installed on the bottom of the base. The height-increasing structure can be adsorbed onto the supporting point where the pad is located, thereby achieving height increase and meeting the typing height requirements of different users; in addition, only through magnetic suction cooperation, an offset in the plane direction may occur during the user's use of the dragging keyboard, and the cooperation between the avoidance groove and the pad just strengthens the positioning, making the installation of the height-increasing structure more secure.

[0007] A further solution is that at least the lower part of the height-increasing structure is made of elastic material.

[0008] As can be seen from the above, this setting can increase the friction between the height-enhancing structure and the desktop or other supporting surfaces, thereby solving the problem of slippage during keyboard use.

[0009] A further solution is that the first slot of the first installation slot faces upward and is narrowed, and the edge of the first slot restricts the first magnetic attraction member from above.

[0010] As can be seen from the above, the first notch is opened upward to reduce the impact on the magnetic attraction and ensure sufficient magnetic attraction. At the same time, the narrowed notch design can prevent the first magnetic attraction component from loosening from the first notch.

[0011] Another further solution is that a depression is provided at the bottom of the height-increasing structure to form a gripping protrusion.

[0012] A further solution is that the grip protrusions are distributed in stripes.

[0013] As can be seen from the above, the provision of the gripping protrusions can reduce the contact area and increase the gripping force. Furthermore, the keyboard generally needs to deal with the problem of displacement in the front-to-back direction. The provision of the gripping protrusions in stripes can reduce the contact area in the front-to-back direction while ensuring the contact area in the left-to-right direction, which can better deal with the displacement in the front-to-back direction.

[0014] Another further solution is that the inner connecting seat includes an inner bottom plate, and the second notch of the second mounting groove faces downward.

[0015] As can be seen from the above, opening the second notch downwards can reduce the impact on the magnetic attraction and ensure sufficient magnetic attraction.

[0016] Another further solution is that the cross section of the pad decreases from top to bottom to its own bottom, and the avoidance groove is expanded.

[0017] As can be seen from the above, this arrangement ensures that the pad can easily enter the avoidance groove, reducing the difficulty of installing the height-increasing structure.

[0018] Another further solution is that the inner connecting seat is made of plastic.

[0019] As can be seen from the above, plastic is easy to process into complex contour structures and connection structures, and the carbon fiber base and fixing plate are heavy. In order to avoid further increasing the weight of the keyboard, the internal connection seat with a larger internal volume is molded with lighter plastic to facilitate product lightweighting.

[0020] Another further solution is that the base includes an outer bottom plate, the outer bottom plate is located between the first magnetic attraction component and the second magnetic attraction component, and the thickness of the outer bottom plate is less than 1.2 mm.

[0021] As can be seen from the above, this setting takes into account both the strength of the base and reducing the impact on the magnetic attraction.

[0022] Another further solution is that the fixing plate is made of carbon fiber material, and the fixing plate serves as a surface cover of the carbon fiber keyboard and cooperates with the base.

[0023] As can be seen from the above, this arrangement allows the keyboard fixing plate to directly serve as the keyboard cover, so there is no need to set up an additional cover component, thereby simplifying the product structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] See also Figure 1 , Figure 2 , Figure 3 and Figure 6The carbon fiber keyboard of this embodiment includes the structures of the shell 1, the liner 2, the keycap 3 and the pad 4 of the previous carbon fiber keyboard, and further includes a first height-increasing structure 5 and a second height-increasing structure 6. The first height-increasing structure 5 and the second height-increasing structure 6 are two groups of height-increasing structures that can be optionally installed in the utility model, and the height-increasing bodies included in the two have a height difference. In this embodiment, the height of the height-increasing body of the second height-increasing structure 6 is greater than the height of the height-increasing body of the first height-increasing structure 5. The height-increasing structure is specifically described below by taking the first height-increasing structure 5 as an example.

[0032] In this embodiment, the housing 1 includes a base 11 and an inner connecting seat 12. The base 11 is made of carbon fiber material, and the inner connecting seat 12 is made of plastic. The base 11 includes an outer bottom plate 111 and the inner connecting seat 12 includes an inner bottom plate 121. The lower surface of the inner bottom plate 121 is bonded to the inner wall surface of the outer bottom plate 111 by 3M adhesive, so that the inner connecting seat 12 is fixedly connected to the base 11. Four pads 4 are bonded to the bottom surface 119 of the outer bottom plate 111 of the base 11. The pads 4 are made of rubber material, and the cross section of the pads 4 decreases from top to bottom to the bottom of the pads 4.

[0033] The liner 2 includes a circuit board 22, a fixing plate 21, a key shaft switch 23, and some silent or vibration-reducing material layers. A plurality of key shaft switches 23 are inserted on the fixing plate 21 and electrically connected to the circuit board 22, and the key cap 3 is connected to the key shaft switch 23. In this embodiment, the fixing plate 21 is made of carbon fiber material. The fixing plate 21 is used as the surface cover of the carbon fiber keyboard and cooperates with the base 11, covering the outer peripheral wall of the base 11. The inner connection seat 12 is provided with a screw hole column, and the fixing plate 21 is provided with a connection hole. The screw hole column supports the fixing plate 21 and is locked by screws.

[0034] See also Figures 4 to 7 The first height-increasing structure 5 includes a height-increasing body 51 and a first magnetic member 71. The top of the height-increasing body 51 is provided with an upwardly opening avoidance groove 511 and a first installation groove 512. The first magnetic member 71 is arranged in the first installation groove 512. More specifically, in this embodiment, the height-increasing body 51 is made of rubber material as a whole, and a depression 513 is provided at the bottom of the first height-increasing structure 5 and a gripping protrusion 514 is formed. The gripping protrusion 514 is distributed in stripes. The extending direction of the stripes is the length direction of the keyboard, that is, the left-right direction of the keyboard; the distribution direction of the stripes is the width direction of the keyboard, that is, the front-back direction of the keyboard.

[0035] See also Figure 7 The first slot 5120 of the first installation slot 512 is upward and narrowed, and the edge of the first slot 5120 forms a surrounding retaining ring to restrict the first magnetic member 71 from above to prevent the first magnetic member 71 from loosening. The avoidance slot 511 is flared, and the size of the avoidance slot 511 gradually increases from the bottom to the third slot 5110.

[0036] Continue to see Figure 7 , a second mounting groove 120 is provided on the inner bottom plate 121 of the inner connecting seat 12, the second notch 1201 of the second mounting groove 120 faces downward, and the second magnetic member 72 is provided in the second mounting groove 120, so that the outer bottom plate 111 of the base 11 blocks the second notch 1201 from below and restricts the second magnetic member 72 to prevent the second magnetic member from loosening. In this embodiment, the first magnetic member 71 and the second magnetic member 72 are both magnets. In other embodiments, one of the first magnetic member 71 and the second magnetic member 72 is a magnet and the other is a magnetic conductive metal member.

[0037] See also Figure 1 , Figure 2 and Figure 7 The first height-increasing structure 5 and the second height-increasing structure 6 can be selectively and detachably installed outside the base 11 and supported below the bottom surface 119. Figure 1 and Figure 7 In the state shown, the first height-increasing structure 5 is selected for installation. The height-increasing structure is mainly installed near the rear of the keyboard, and the front of the keyboard does not need to be provided with a height-increasing structure. The front of the keyboard is the part close to the space key in the width direction of the keyboard.

[0038] At this time, if Figure 7 As shown, the pad 4 is located in the avoidance groove 511, and the first magnetic member 71 and the second magnetic member 72 are opposite to each other and attracted to each other. In this way, height-increasing structures of different heights can be adsorbed to the support point where the pad 4 is located, thereby achieving height increase and meeting the tapping height requirements of different users. In addition, only through magnetic attraction, the user may cause a plane deviation during the process of dragging the keyboard, and the avoidance groove 511 and the pad 4 cooperate just to strengthen the positioning, making the installation of the first height-increasing structure 5 more secure.

[0039] In addition, the cross-sectional gradient design of the cushion block 4 and the expansion design of the avoidance groove 511 enable the cushion block 5 to easily enter the avoidance groove 511 when installing the first height-increasing structure 5 , thereby reducing the difficulty of installing the first height-increasing structure 5 .

[0040] In addition, in this embodiment, the thickness of the outer bottom plate 111 between the first magnetic member 71 and the second magnetic member 72 is only 1 mm, and because the second notch 1201 of the second mounting groove 120 faces downward and the first notch 5120 of the first mounting groove 512 faces upward, this arrangement can well eliminate the influence of the magnetic attraction, ensuring that the height-enhancing structure is firmly attracted to the base 11. In order to ensure strength, the thickness of the peripheral wall of the base 11 can be greater than or equal to 1.2 mm.

[0041] In other embodiments, at least the lower portion of the first height-increasing structure 5 is made of an elastic material, and the elastic material may be a silicone material in addition to a rubber material.
