Description

Technical Field

[0001] The invention relates to the technical field of keyboards, in particular to a keyboard with keys of an X-shaped connection component. Background Art

[0002] At present, many products and devices use keys as a component, such as keyboards. Keyboard keys are the core components of keyboards. A high-quality keyboard is inseparable from high-quality keys. At present, there are many types of products in the keyboard market, and the technology is becoming more complex, especially the key technology is constantly improving. The keys in the prior art usually adopt a scissor foot structure, which can effectively shorten the key travel and effectively reduce the user's fatigue. The durability is also better than the crater structure, and it can effectively reduce the situation of key sticking. However, the keys with the scissor foot structure in the prior art usually have the fulcrums of the two brackets rotatably set, and a clearance distance is set between the bracket and the keycap so that the bracket can extend into the clearance distance when it rotates to achieve the movement of the bracket relative to the keycap. Such a structure requires the keycap to have a larger size in order to achieve the clearance distance. Some keys also achieve the movement of the bracket relative to the keycap by sliding the two brackets. Such a structure cannot achieve a unilateral sliding setting. The two brackets of the scissor foot need to slide at the same time, and the structural stability is poor. When the two brackets slide, it is easy for the two brackets to be unevenly stressed due to the different points of application of the force applied by the user to the keycap, resulting in the keycap tilting in different directions, and the fulcrums of the two brackets are easily affected by each other.

[0003] The publication number "CN113436922A" provides an X-structure key and keyboard, the key comprising a key cap, an X-structure bracket, an elastic body, a bracket plate, and a circuit board; the elastic body is connected to the circuit board; the X-structure bracket is connected to the bracket plate, the key cap is connected to the X-structure bracket and is located above the elastic body; the X-structure bracket comprises a first bracket and a second bracket, one end of the first bracket is hinged to one end of the second bracket, one end of the first bracket is provided with a sliding fulcrum, one end of the second bracket is provided with a fixed fulcrum, and the bracket plate is provided with a first supporting part and a second supporting part; the sliding fulcrum is rotatably connected to the first supporting part and can slide relative to the first supporting part; the fixed fulcrum is only rotatably connected to the second supporting part; thereby, the X-structure is realized in a relatively unilateral sliding arrangement, the X-structure bracket is realized, the size of the key cap is reduced, and the two brackets do not need to slide at the same time, so that the structure is more stable.

[0004] However, the above device still has the following problems during implementation: Although the existing X-shaped structure can better ensure the stability of the key, due to the high frequency of use of the key, after long-term use, the cross structure may be deformed to a certain extent, eventually resulting in poor resetting of the key.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-7 , the present invention provides a technical solution.

[0021] Embodiment 1: A keyboard with an X-shaped connection component key, comprising a keyboard support plate 1 and a key 2 installed above the keyboard support plate 1, wherein the key 2 comprises a key cap 6 and a base 7, an X-shaped connection component is arranged between the key cap 6 and the base 7, and the X-shaped connection component comprises a first bracket 9 and a second bracket 10, wherein the first bracket 9 and the second bracket 10 are both pin-connected to the upper surface of the base 7, and the first bracket 9 and the second bracket 10 are pin-connected; a pulley 11 is arranged on the top of each of the first bracket 9 and the second bracket 10, and the pulley 11 is slidably connected to the inner top surface of the key cap 6; In this embodiment, the key 2 includes a keycap 6 and a base 7. An X-shaped connecting component is arranged between the keycap 6 and the base 7 to prevent the key 2 from tilting when being struck. The key is positioned by the first bracket 9 and the second bracket 10 of the X-shaped connecting component. The first bracket 9 and the second bracket 10 are cross-pinned to form an X-shaped connecting component. Specifically, the first bracket 9 and the second bracket 10 are arranged in an X-shaped cross structure, and the first bracket 9 and the second bracket 10 are pin-connected. The pulley 11 is rotatably connected to the top of the first bracket 9 and the second bracket 10 through a connecting shaft.

[0022] The upper surface of the base 7 is symmetrically provided with ear plates 12 , the first bracket 9 and the second bracket 10 are respectively pinned between two adjacent groups of ear plates 12 , and a torsion spring is provided inside the ear plate 12 .

[0023] It should be noted that, due to the working requirements of the key 2 , torsion springs are provided at the ear plate 12 and at the positions where the ear plate 12 is pinned to the first bracket 9 and the second bracket 10 respectively, so as to provide the key cap 6 with a timely resetting function.

[0024] Due to the arrangement of the above structure, when any position of the key 2 is pressed, the X-shaped connection assembly can make the key cap 6 always reciprocate up and down perpendicular to the center of the base 7, so that during the pressing process, the key is not easy to tilt or get stuck, thereby ensuring that the switch is labor-saving to operate, smooth to the touch, and good to the touch during the pressing process.

[0025] It should be noted that due to friction and other reasons during use, the X-shaped connection assembly may affect the action direction of the keycap 6 after a certain period of use, so a groove is provided in the keycap 6, and six groups of connecting sleeves 14 are symmetrically arranged in the groove. Six groups of guide rods 8 are symmetrically arranged on the upper surface of the base 7, and the top of the guide rod 8 is connected to a guide pin 13. The cross section of the guide pin 13 is arranged in a cross-rod structure, and a cross slot is provided in the connecting sleeve 14. The guide pin 13 and the connecting sleeve 14 are arranged for sliding insertion.

[0026] By means of the slidably inserted guide pin 13 and the connecting sleeve 14, acting on both sides of the X-shaped connecting assembly, the key cap 6 and the base 7 are better limited in vertical movement, further ensuring that the key is not prone to tilting or getting stuck.

[0027] The guide rails 25 are symmetrically installed in the groove of the key cap 6. Two sets of guide grooves are opened in the guide rails 25, and the pulleys 11 are slidably connected in the guide grooves.

[0028] In this embodiment, a groove is opened in the keycap 6, and a guide rail 25 is arranged in the groove. It should be noted that since the pulleys 11 at the top of the first bracket 9 and the second bracket 10 are not arranged in a colinear structure in the vertical direction, two sets of guide grooves are opened in the guide rail 25, which are respectively used to limit the pulleys 11 at the top of the first bracket 9 and the second bracket 10.

[0029] Specifically, limiting grooves are additionally provided on both sides of the guide groove to provide space for the end of the connecting shaft at one end of the pulley 11 , so that the key cap 6 can be elastically connected to the base 7 through the X-shaped connecting assembly while the pulley 11 slides.

[0030] It should be noted that the first bracket 9 and the second bracket 10 are symmetrically arranged on both sides of the button. When the user presses the button at an angle, the torsion spring at the pin-jointed position of the first bracket 9 and the second bracket 10 follows the rotation of the two groups of crossed brackets to offset the component of the pressing force in the tilted direction, further preventing the button from tilting or getting stuck, thereby ensuring smooth use.

[0031] Since the first X-shaped connecting component of the first bracket 9 and the second bracket 10 are slidably connected on both sides through the guide pin 13 and the connecting sleeve 14, the friction between the first bracket 9 and the second bracket 10 and the key 2 and the keyboard tray 1 is reduced, while avoiding the key from tilting, ensuring smoothness of use and avoiding deformation of the X-shaped connecting component in the key 2 during operation.

[0032] It should be noted that a mounting hole 16 is provided in the keyboard support plate 1 , and a positioning column 15 is provided at the bottom of the base 7 , and the positioning column 15 is used to locate the installation position of the base 7 in the keyboard support plate 1 .

[0033] Embodiment 2: Based on the first embodiment, since the key is supported by an X-shaped connection assembly, a certain distance is generated between the keycap 6 and the keyboard support plate 1, which is easy to accumulate dust. Therefore, in this embodiment, an easy-to-operate cleaning assembly is proposed to clean the connection position of the key 2 at any time. Specifically, the keyboard support plate 1 is provided with a cleaning assembly, and a lever 5 is provided on one side of the cleaning assembly. The sliding lever 5 can drive the cleaning assembly to work and clean the deposits at the key installation position.

[0034] The keyboard support plate 1 is provided with a pull-out cleaning tray 3, the cleaning assembly is provided in the cleaning tray 3, and the lever 5 extends to the outside of the cleaning tray 3. A limit plate is provided on one side of the cleaning tray 3, a slide groove 4 is provided in the limit plate, and one end of the lever 5 slides in the slide groove 4.

[0035] In this embodiment, a cleaning tray 3 is provided to support the entire cleaning assembly. A lever 5 is provided in the cleaning assembly to confine the lever 5 in the slide groove 4. One end of the lever 5 extends to the outside of the keyboard tray 1 and is located on the user's working side, so that the cleaning assembly in the cleaning tray 3 can be driven to move through the lever 5.

[0036] The cleaning assembly includes a linear guide rail 23 disposed in the cleaning disc 3, and two groups of mounting brackets 24 are symmetrically disposed on the slider of the linear guide rail 23. A cleaning brush wheel 20 is rotatably mounted in the mounting bracket 24, and a brush 21 is arranged in an annular equidistant array on the surface of the cleaning brush wheel 20. A rack 18 is disposed in the cleaning disc 3 on one side of the linear guide rail 23, and a gear 19 is meshed above the rack 18. A lever connecting shaft 22 is fixedly connected in the gear 19, and one end of the lever connecting shaft 22 is rotatably connected to one end of the lever 5. The cleaning brush wheel 20 is fixedly connected to the lever connecting shaft 22, and the lever connecting shaft 22 is rotatably connected in the two groups of mounting brackets 24.

[0037] Specifically, after the keyboard has been used for the first period of time, the user can move the lever 5 to make it reciprocate in the slide groove 4, and connect the lever connecting shaft 22 through the lever 5 to drive the cleaning brush wheel 20 to move on the linear guide 23. When moving, due to the meshing connection between the gear 19 and the rack 18, the lever connecting shaft 22 rotates following the rotation of the gear 19, thereby driving the cleaning brush wheel 20 to rotate. The brush 21 on the outer ring of the cleaning brush wheel 20 repeatedly cleans the connection position between the key 2 and the keyboard tray 1, cleans the dust accumulated at the connection position, ensures that the electrical connection structure of the key is not affected by the dust accumulation, and ensures the sensitivity of the key.

[0038] Embodiment three: Based on the first embodiment, in order to avoid the phenomenon that the two brackets are unevenly stressed and the keycaps tilt in different directions due to the different points of application of the force applied to the keycaps by the user, in the present embodiment, a V-shaped structure is arranged between the keycaps 6 and the base 7, and the V-shaped structure includes a left bracket 26 and a right bracket 27, and the left bracket 26 and the right bracket 27 are pinned together by a bracket pin 30, and a second keycap pin 29 is symmetrically arranged on one side of the left bracket 26, and a first keycap pin 28 is symmetrically arranged on one side of the right bracket 27, and the first keycap pin 28 and the second keycap pin 29 are pinned together with the keycap 6 by buckling, and a fixed fulcrum pin 31 and a sliding fulcrum pin 32 are respectively arranged on the left bracket 26 and the right bracket 27 near the bracket pin 30, and the fixed fulcrum pin 31 is fixedly pinned to the upper surface of the base 7, and the sliding fulcrum pin 32 is slidably pinned to the upper surface of the base 7.

[0039] The present embodiment realizes a relatively unilateral sliding setting of the V-shaped structure, which can effectively reduce the design size of the keycap 6, and the left bracket 26 and the right bracket 27 do not need to slide at the same time, making the structure more stable. When both brackets can slide, the left bracket 26 and the right bracket 27 will not be subjected to uneven force and the keycap 6 will not tilt in different directions due to the different points of application of the force applied by the user to the keycap 6. The fulcrums of the left bracket 26 and the right bracket 27 will not be affected by each other, which further optimizes the stability when the keys are struck.

[0040] Working principle: This device uses an X-shaped connection structure. When pressing any position of the key 2, the X-shaped connection component can make the key cap 6 always reciprocate up and down perpendicular to the center of the base 7, so that during the pressing process, the key is not easy to tilt or get stuck, thereby ensuring that the switch is labor-saving, smooth, and has a good finger pressure touch during the pressing process; After the device has been used for a certain period of time, the lever 5 is moved, and the lever connecting shaft 22 is connected through the lever 5 to drive the cleaning brush wheel 20 to move on the linear guide rail 23. When moving, due to the meshing connection between the gear 19 and the rack 18, the lever connecting shaft 22 rotates along with the rotation of the gear 19, thereby driving the cleaning brush wheel 20 to rotate. The brush 21 on the outer ring of the cleaning brush wheel 20 repeatedly cleans the connection position between the key 2 and the keyboard support plate 1, cleans the dust accumulated at the connection position, ensures that the electrical connection structure of the key is not affected by the dust, and ensures the sensitivity of the key.

[0041] In summary: The present invention mainly realizes an embedded X-shaped connection component structure by setting an X-shaped connection component, and embedding the embedded part of the X-shaped connection component on the base 7, so that the first bracket 9 and the second bracket 10 of the X-shaped connection component are respectively connected between the key cap 6 and the base 7, thereby improving the overall structural strength of the key, and improving the action stability of the X-shaped connection component, and ensuring the balance of the force action of the key, thereby effectively preventing the phenomenon of skewing and key jamming during key action, and having a better operating feel during key action; The X-type connection assembly can be relatively fixed on the bracket plate, which is conducive to the automation of the assembly of the X-type connection assembly and the automation of the whole group of keys, which can greatly improve the production efficiency; and, by setting the fulcrums at the top of the first bracket 9 and the second bracket 10 as sliding fulcrums; the fulcrums at the bottom of the first bracket 9 and the second bracket 10 are set as fixed fulcrums, so that the sliding fulcrums are limited in the guide rails 25 in the keycap 6, so that it realizes the cross-rotation compression structure of the X structure, and realizes the double-shear type X-type connection assembly. When the first bracket 9 and the second bracket 10 are forced to slide at the same time, the structure is made more stable. With the support guide structure of the guide pin 13 and the connecting sleeve 14, when both brackets can slide, the two brackets will not be unevenly stressed and the keys will not tilt in different directions due to the different points of action of the force applied by the user to the keys, and the fulcrums of the two brackets will not be affected by each other.

[0042] It should be noted that the electrical connection structure of key 2 and the circuit inside the keyboard are devices or equipment existing in the prior art, or are devices or equipment that can be implemented in the prior art. Their power supply, specific composition and principles are clear to technical personnel in this field, so they will not be described in detail.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
