Description

Technical Field

[0001] This invention belongs to the field of keyboard technology, and particularly relates to a keyboard buffer structure. Background Technology

[0002] A keyboard is a device used to input instructions and data to operate equipment. It is the most commonly used and primary input device, allowing users to input English letters, numbers, punctuation marks, and other symbols into a computer, thereby issuing commands and inputting data.

[0003] Figure 1 This is a schematic diagram of an existing gasket-structured keyboard. This keyboard structure includes a keyboard base 1, a positioning plate 2 mounted on the keyboard base 1, a keyboard top frame 3 located on the positioning plate 2, and connecting bolts 4 for connecting the keyboard base 1, positioning plate 2, and keyboard top frame 3 together. The positioning plate has through holes for the connecting bolts 4 to pass through. Deformable cushioning strips 6 are provided on the upper and lower sides of the positioning plate 2. Both the keyboard base 1 and the keyboard top frame 3 have receiving grooves 5 to accommodate the cushioning strips 6. Since the cushioning strips 6 will deform laterally when pressed up and down, the length of the receiving groove 5 is greater than the length of the cushioning strips 6. This causes the positioning plate 2 and the cushioning strips 6 to sway left and right on the keyboard base 1 and the keyboard top frame. When the connecting bolts 4 connect the keyboard base 1, positioning plate 2, and keyboard top frame 3, the swaying of the positioning plate 2 makes it difficult for the connecting bolts 4 to align with the through holes on the positioning plate 2, which is inconvenient for workers to assemble. Summary of the Invention

[0004] The purpose of this invention is to provide a keyboard buffer structure that is easy to assemble, in order to solve the technical problem in the prior art where the positioning plate shakes, making it difficult for the connecting bolts to align with the through holes on the positioning plate, which is inconvenient for workers to assemble.

[0005] To achieve the above objectives, an embodiment of the present invention provides a keyboard buffer structure, including a keyboard base and a guide mechanism located within the keyboard base. The guide mechanism acts on a positioning plate to make the positioning plate move only along its force direction. A buffer element is provided between the positioning plate and the keyboard base to make the positioning plate and the keyboard base non-rigidly connected.

[0006] Furthermore, the guiding mechanism consists of several guide posts mounted on the keyboard base, which are slidably connected to the positioning plate.

[0007] Furthermore, the guiding mechanism consists of guide ribs formed on the inner walls of both sides of the keyboard base, with the positioning plate slidably connected to the guide ribs, and the positioning plate having a limiting groove corresponding to the guide ribs.

[0008] Furthermore, the upper end of the guide post is provided with an external thread, and the guide post is provided with a movable part with an internal thread that can mate with the external thread. The minor diameter of the external thread is greater than or equal to the diameter of the guide post. The buffer element is located between the movable part and the keyboard base, and the positioning plate is set on the movable part.

[0009] Furthermore, the buffer element is the first spring.

[0010] Furthermore, the buffer element is a cushioning sponge.

[0011] Furthermore, it also includes a limiting mechanism set on the guide column, which is used to prevent the positioning plate from moving away from the bottom of the keyboard base.

[0012] Furthermore, the limiting mechanism is a fastening bolt installed at the upper end of the guide post along the axial direction of the guide post, and the fastening bolt is threadedly connected to the guide post.

[0013] Furthermore, it also includes a limiting mechanism installed on the keyboard base, which is used to prevent the positioning plate from moving away from the bottom of the keyboard base.

[0014] Furthermore, the limiting mechanism is a sliding block mounted on the guide rib, with a second spring between the block and the guide rib. The bottom of the block contacts the top of the positioning plate, and the block or the positioning plate is provided with a guide sidewall that squeezes and guides the block away from the positioning plate when it contacts the positioning plate.

[0015] The keyboard buffer structure provided in this embodiment of the invention has at least one of the following technical effects: by setting the guide mechanism, the positioning plate moves only along its force direction under the action of the guide mechanism, realizing a non-rigid connection between the positioning plate and the keyboard base while preventing the positioning plate from shaking in other directions, which facilitates the assembly of the keyboard by workers.

[0035] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The following description is based on the accompanying drawings. Figure 2-12 The described embodiments are exemplary and intended to explain embodiments of the invention, and should not be construed as limiting the invention.

[0036] In the description of the embodiments of the present invention, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of the present invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0038] In the embodiments of the present invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.

[0039] In one embodiment of the present invention, such as Figure 2-12 As shown, a keyboard buffer structure is provided, including a keyboard base 1 and a positioning plate 2 that can move within the keyboard base 1. A buffer element is provided between the positioning plate 2 and the keyboard base 1 to make the positioning plate 2 and the keyboard base 1 non-rigidly connected. A guide mechanism is provided inside the keyboard base 1. The guide mechanism acts on the positioning plate 2 to make the positioning plate 2 move only in the direction of its force. Under the action of the guide mechanism, the positioning plate 2 and the keyboard base 1 are non-rigidly connected while preventing the positioning plate 2 from shaking in other directions.

[0040] Figure 4-7 As shown in the figure, the guide mechanism consists of several guide posts 11 disposed at the bottom of the keyboard base 1. The guide posts 11 are cylindrical. The positioning plate 2 has several cylindrical through holes corresponding to the guide posts 11. The guide posts 11 pass through the through holes and are slidably connected to the positioning plate 2. The diameter of the through holes is equal to the diameter of the guide posts 11, so that the positioning plate 2 moves only in the direction of its force.

[0041] Since the positioning plate 2 and the keyboard assembly subsequently mounted on the positioning plate 2 are both supported on the elastic element, and in order to provide users with a better typing feel, the cushioning element has a certain degree of compression resistance, such as... Figure 6-7 As shown, the buffer elements are all sleeved on the guide post 11. At this time, the buffer elements are in a compressed state and have a certain resistance to compression. When the positioning plate 2 is not yet assembled on the guide post 11, the initial height of the buffer elements is higher than the height of the guide post 11. Since there are multiple through holes on the positioning plate 2, the through holes need to be aligned with multiple guide posts 11 at the same time during assembly. The initial height of the buffer elements being higher than the height of the guide post 11 will make it difficult for the guide post 11 to be aligned with the through holes on the positioning plate 2, which is not conducive to the assembly of the positioning plate 2.

[0042] Furthermore, the upper end of the guide post 11 is provided with an external thread 111, and the guide post 11 is provided with a movable part 21 with an internal thread 211 that can mate with the external thread 111. The minor diameter of the external thread 111 is greater than or equal to the diameter of the guide post 11, and the major diameter of the external thread 111 is equal to the diameter of the through hole of the positioning plate 2. The buffer element is located between the movable part 21 and the keyboard base 1. When installing the movable part 21, first manually compress the buffer element so that the upper end of the guide post 11 with the external thread 111 protrudes from the buffer element, and then thread the movable part 21 with the external thread 111. Continuously rotate the movable part 21 so that the movable part 21 moves along the guide post 11. As the moving part moves downward, the buffer element is compressed under the pressure of the movable part 21. Since the minor diameter of the external thread 111 is greater than or equal to the diameter of the guide post 11, when the movable part 21 moves downward and disengages from the external thread 111, the movable part 21 can still slide up and down on the lower section of the external thread 111 of the guide post 11. When the movable part 21 slides, the upper external thread 111 can provide a blocking effect to prevent the movable part 21 from disengaging from the guide post 11 due to the elastic force of the buffer element's reset, so that the buffer element always remains in a compressed state. When all the guide posts 11 are equipped with movable parts 21, the positioning plate 2 is then placed on the movable parts 21.

[0043] In this embodiment, the buffer element is a first spring 3 sleeved on the guide post 11, or a buffer sponge 31 sleeved on the guide post 11.

[0044] The aforementioned guide post 11 is fixed to the keyboard base 1 by riveting. Compared with bolt fixing or other methods, riveting is a lower fixing cost while still meeting the fixing requirements.

[0045] Furthermore, it also includes a limiting mechanism set on the guide post 11. The limiting mechanism is used to prevent the positioning plate 2 from moving away from the bottom of the keyboard base 1. Preventing the positioning plate 2 from moving away from the bottom of the keyboard base 1 can prevent the keycaps from shaking away from the bottom of the keyboard base 1 during the use of the keyboard.

[0046] The aforementioned limiting mechanism is a fastening bolt 4 set along the axial direction of the guide post 11 at the upper end of the guide post 11. The fastening bolt 4 is threadedly connected to the guide post 11. After the positioning plate 2 is assembled on the guide post 11, the fastening bolt 4 is threadedly connected to the guide post 11, and the fastening bolt 4 is rotated to move downwards and contact the positioning plate 2, thereby preventing the positioning plate 2 from moving away from the bottom of the keyboard base 1.

[0047] Furthermore, such as Figure 6-7 As shown, the bottom of the movable part 21 is provided with a limiting block 6 extending into the bottom of the keyboard base 1. The limiting block 6 is used to limit the downward movement distance of the positioning plate 2, so that the typing feel is more consistent and the positioning plate 2 will not move downward excessively due to excessive key pressure.

[0048] Figure 2 As shown in the figure, in another embodiment of the guiding mechanism, the guiding mechanism is a guide rib 12 formed on the inner walls of both sides of the keyboard base 1. The guide rib 12 can be integrally formed on the keyboard base 1. The positioning plate 2 is provided with a limiting groove corresponding to the guide rib 12. The positioning plate 2 is slidably connected to the guide rib 12 through the limiting groove. Compared with the guide post 11 mentioned in the above embodiment, the integrally formed guide rib 12 reduces the fixing process of fixing the guiding mechanism to the keyboard base 1, and improves the production efficiency of the keyboard.

[0049] In this embodiment, the buffer element is a first spring 3 disposed between the positioning plate 2 and the bottom of the keyboard base 1, or a buffer sponge 31 disposed between the positioning plate 2 and the bottom of the keyboard base 1.

[0050] Furthermore, it also includes a limiting mechanism disposed on the keyboard base 1, which is used to prevent the positioning plate 2 from moving away from the bottom of the keyboard base 1.

[0051] like Figure 8-9 As shown, the limiting mechanism is a sliding block 5 mounted on the guide rib 12. A second spring 51 is provided between the block 5 and the guide rib 12. The bottom of the block 5 contacts the top of the positioning plate 2. The mechanism also includes a guide sidewall that squeezes and guides the block 5 away from the positioning plate 2 when it contacts the positioning plate 2.

[0052] The aforementioned guide sidewall can be provided at the upper end of the locking block 5, such as... Figure 8-11As shown, the guide sidewall is a wedge-shaped end face that extends downward from the top of the latch 5. When assembling the positioning plate 2, the positioning plate 2 is moved downward along the guide rib 12. The edge of the bottom of the positioning plate 2 limiting groove contacts the wedge-shaped end face of the latch 5 as the positioning plate 2 moves. Under the action of the wedge-shaped inclined surface, the positioning plate 2 squeezes the latch 5, causing the latch 5 to move away from the positioning plate 2. The second spring 51 is compressed. When the positioning plate 2 no longer squeezes the latch 5, the positioning plate 2 is located below the latch 5. The latch 5 pops out under the action of the second spring 51, so that the bottom of the latch 5 is located above the positioning plate 2, thereby preventing the positioning plate 2 from moving away from the bottom of the keyboard base 1. Under the action of the first spring 3, the top of the positioning plate 2 contacts the bottom of the latch 5.

[0053] Furthermore, such as Figure 9 and 11 As shown, the bottom of the positioning plate 2 is provided with a limiting block 6 extending into the bottom of the keyboard base 1. The limiting block 6 is used to limit the downward movement distance of the positioning plate 2, so that the typing feel is more consistent and the positioning plate 2 will not move downward excessively due to excessive key pressure.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
