如第2Β圖所示，於此實施方式中，當按鍵12位於最 低按壓位置時，第一連桿120a之滑軸120c恰好正對滑槽 結構122a與擔臂122b所形成之組裝口 122c。換句話說， 在將鍵帽122組裝至剪刀式支撐結構12〇時，只要將按鍵 12之鍵帽122垂直地按壓剪刀式支撐結構12〇至最低按壓 位置，即可使第二連桿120b之固定軸i20d與鍵帽122之 第二樞接結構122g銜接，並同時使第一連桿12〇a之滑軸 120c擠壓通過組裝口 122c以銜接至鍵帽122之滑槽結構 122a。並且，如第2B圖所示，當按鍵12位於最低按壓位 9 M405002 置時，第一連桿120a之滑軸120c的大部分位於滑槽結構 122a外，但卻不必擔心滑轴12〇c脫離滑槽結構122&，因 為鍵巾s 122之擋臂i22b會防止滑軸i2〇c脫離滑槽結構 122a。因此相較於習知技術’本實施方式之鍵帽122可以 採用較短的滑槽結構122a’滑槽結構122a的強度即可獲得 k升，在將鍵帽122組裝於剪刀式支標結構丨20的過程中， 可以有效減少鍵帽122或剪刀式支撐結構120的損壞。 請參照第3圖，其為繪示第2A圖中之鍵帽122的局 部放大圖。 如第3圖所示，於本實施方式中，為了在將鍵帽I” 組裝至剪刀式支撐結構120的過程中更順暢，鍵帽122之 滑槽結構122a於組裝口 122c處可包含有第一導引面 122d ’並且鍵帽122之擋臂122b於組裝口 122c處同樣可 包含有第二導引面122f。藉此，滑槽結構122a之第一導引 面122d與擋臂122b之第二導引面122f即可在第一連桿 120a之滑軸120c通過組裝口 122c時導引滑軸120c，使得 滑轴120c與滑槽結構122a以及擋臂122b之間的摩擦力大 幅減少，進而有效減少滑軸120c、滑槽結構122a或擋臂 122b的損壞。 同樣示於第3圖中，於本實施方式中，鍵帽122之播 臂122b還可包含有勾部122e。換句話說，組裝口 122c即 形成於鍵帽122之滑槽結構122a與擋臂122b之勾部122e 之間，並且第二導引面122f即位於勾部i22e上。藉由擔 臂122b之勾部122e的結構設計’更可加強防止第一連桿 120a之滑軸120c離開鍵帽122之滑槽結構丨22a並從組裝 M405002 σ 122c脫離的功能。 由以上對於本創作之具體實施例之詳述，可以明顯地 本财讀鍵及其_，主要是針賴帽上用以供 、’刀式支㈣構之滑㈣行銜接之結構進行改良。當鍵帽 以滑槽結構與擋臂之間之組裝口垂直地朝向滑軸擠壓時， 滑轴即可藉由滑槽結構與射的彈性變形以通過包袭口， 進而與滑槽結構銜接。因此，本創作之鍵帽只需要垂直地 朝向剪刀式支撐結構擠壓的單一步驟，即可進行組裝，而 不需如以往必須先將鍵帽斜向地組裝至剪刀式支撐^構上 的步驟。並且’由於鍵帽包含有射，因此滑槽結構的長 度可以縮短，使得在將鍵帽組裝於剪刀式支撐結構上的過 程中，可有效地減少鍵帽或剪刀式支撐的損壞。 雖然本創作已以實施方式揭露如上，然其並非用以限 定本創作，任何熟習此技藝者，在不脫離本創作之精神和 範圍内，當可作各種之更動與潤飾，因此本創作之保護範 圍當視後附之申請專利範圍所界定者為準。 【圖式簡單說明】 第1圖為繪示依照本創作一實施方式之鍵盤的立體視 圖。 第2Α圖為繪示第1圖中之按鍵的側視圖，其中鍵帽 處於未按壓位置。 第2Β圖為繪示第1圖中之按鍵的側視圖，其中鍵帽處 於最低按壓位置。 第3圖為繪示第2Α圖中之鍵帽的局部放大圖。 M405002 【主要元件符號說明】 1 :鍵盤 100a :第一樞接結構 12 .按鍵 120a :第一連桿 120c、120g :滑軸 120e :樞軸 122a :滑槽結構 122c :組裝口 122e :勾部 122g :第二樞接結構 10 :底板 100b ··限位結構 120 :剪刀式支撐結構 120b :第二連桿 120d、120f :固定軸 122 :鍵帽 122b :擋臂 122d :第一導引面 122f :第二導引面 124 :圓頂= The cylinder 'for the vertical expansion movement of the opening of the base = = = = structural limitation, this computer _ key cap tilt, or there is a card key, etc., it is easy to occur contact surface to increase the stability of the keycap Need to hunt up the above-mentioned Hui's because the key cap fish bottom temple has a vertical extension of the _, making the key bribe difficult to be ^ ^ ^ = the unstable sway of the key cap, and the actual operation (four) sound is also another A question is reduced, in view of the increasing importance of light and short computers (chains such as carrying a type of computer), if the distance between the keycap and the base is increased in order to solve the stability of the vertical movement of the keycap, the overall thickness of the disk will increase significantly. That is, it is difficult to meet the requirements of light, thin and short conditions. A double-link parallel mechanism (i.e., a scissor-type support structure) is used to guide the keycap (4) to move straight and balance the user's force on each button. Thereby, regardless of the force applied to the side or corner of the button, the force can be evenly distributed over the entire button surface, making it easy to press the entire button' also makes it easier for the user to operate the button, and can Solve the lack of the above-mentioned vertical cylindrical keycap. However, the assembly type 4 M405002, which currently assembles the keycap on the scissor support structure, often has to be assembled manually, and must be assembled into at least two steps. First, the slider cover of the keycap must be engaged obliquely with the sliding shaft of the scissor support structure, and then the pivoting portion of the keycap is engaged with the fixed shaft of the cutter support structure. It can be seen that the above-mentioned manual assembly method can not easily improve the assembly speed, and may easily cause omission in assembly without knowing. In addition, since the assembly force is difficult to control, it is also liable to cause damage to the keycap or scissor support structure in the button. [New content] In order to solve the problem of the prior art, one of the technical aspects of the present invention is a button, which is mainly for improving the structure of the keycap for the connection of the sliding shaft of the scissor support structure. When the key cap is pressed perpendicularly toward the sliding shaft by the assembly port between the sliding groove structure and the blocking arm, the sliding shaft can be elastically deformed by the sliding groove structure and the blocking arm to pass through the assembly port, thereby engaging with the sliding groove structure. . Therefore, the key cap of the present invention can be assembled only by a single step of pressing vertically toward the scissor support structure, without the need to assemble the keycap obliquely to the scissor support structure as in the past. According to an embodiment of the present invention, a button includes a scissor support structure and a keycap. The scissor support structure includes a first link. The first link has a sliding shaft. The keycap includes a chute structure and a stop arm. The slide shaft is slidably coupled to the chute structure.

The button is set on the bottom plate. The buttons contain a scissor support structure and a keycap. The scissor support structure includes a first link. The first link has a sliding shaft. The keycap includes a chute structure and a stop arm. The slide shaft is slidably coupled to the chute structure. The baffle arm is used to prevent the sliding shaft from coming off the chute structure. An assembly port is formed between the chute structure and the arm. The sliding shaft is coupled to the chute structure through the assembly port, and the assembly port and the sliding shaft are in an interference fit. [Embodiment] A plurality of embodiments of the present invention are disclosed in the following drawings, and for the sake of clarity, many practical details will be described in the following description. However, it should be understood that these practical details are not applied to limit the creation. That is to say, in the implementation part of this creation, these practical details are not necessary. Moreover, some of the conventional structures and elements are shown in the drawings in a simplified schematic manner in order to simplify the drawings. One of the technical aspects of this creation is a keyboard. More specifically, it is primarily intended to improve the structure of the keycap for engaging the sliding shaft of the scissor support structure. When the key cap is pressed perpendicularly toward the sliding shaft by the assembly port between the sliding groove structure and the blocking arm, the sliding shaft can be elastically deformed by the sliding groove structure and the support arm to pass through the assembly port, thereby engaging with the sliding groove structure. . Therefore, the key cap of the present invention can be assembled only by a single step of being vertically pressed toward the scissor support structure, without the need to previously assemble the keycap obliquely to the scissor support structure as in the past. Referring to Fig. 1, there is shown a perspective view of a keyboard 1 in accordance with an embodiment of the present invention. As shown in FIG. 1 , the keyboard 1 of the present embodiment may be an external keyboard (for example, a keyboard) for a desktop type 6 or a keyboard or a keyboard for a keyboard or interface including a keyboard. Computer; = computer system (for example, the hammer of the pen! -r, Ren is not limited to this. In other words, this creation, special 3 is used for any electronic production with the button as the input interface The key of the scissor-type support structure can be solved by the concept of the first one, and the problem of the reduction of the rag can be solved. 2 1 shows that the keyboard i of the embodiment can include the bottom plate 1〇 And a plurality of buttons 12. Each button 12 w is provided on the bottom plate 10. The structure of each component in the button 12 of the present embodiment will be described in detail below. 第 Refer to FIG. 2A and FIG. 2A. FIG. To show a side view of the button 12 in the figure i, wherein the keycap 122 is in the unpressed position. Fig. 2A is a side view showing the button 12 in Fig. 1, wherein the keycap 122 is in the lowest pressed position. 2A and 2B, in the present embodiment, the button 12 can be packaged. There is a scissor support structure 120 and a key cap 122. The scissor structure 120 includes a first link i20a and a second link 120b. The first link i2〇a and the second link 120b of the scissor support structure 120 The bottom plate of the keyboard 1 can further include a first pivotal structure l〇〇a and a limiting structure i〇〇b. The first connection of the scissor support structure 120 One end of the rod 120a adjacent to the bottom plate 10 includes a fixed shaft 120f. The fixed shaft 120f can be pivotally connected to the first pivoting structure 100a of the bottom plate 10. The second link 120b of the scissor support structure 12 is close to the bottom plate. One end of the 1〇 includes a sliding shaft I20g, and the sliding shaft 120g can be slidably limited to the limiting structure 100b of the bottom plate 10. Thereby, the scissor supporting structure 120 of the M405002 button 12 can be disposed on the bottom plate 10. As shown in FIG. 2B, in the present embodiment, the other end of the first link 120a of the scissor support structure 120 may have a sliding shaft 120c, and the other end of the second link 120b may have a fixed shaft 120d. The keycap 122 can include a chute structure 122a and a block The arm 122b and the second pivoting structure 122g. The sliding shaft 120c of the first link 120a is slidably coupled to the sliding slot structure 122a of the keycap 122. The blocking arm 122b of the keycap 122 can be used to prevent the sliding of the first link 120a. The shaft 120c is separated from the chute structure 122a. The fixed shaft 120d of the second connecting rod i2〇b is pivotally connected to the second pivoting structure 122g of the keycap 122. The bottom plate 10, the scissor support structure 120 and the key cap are provided by the above-mentioned bottom plate 10. When the key cap 122 of the button 12 is pressed, the key cap 122 of the button 12 can reciprocate vertically between the unpressed position of FIG. 2A and the lowest pressed position of FIG. 2B. In addition, in the present embodiment, the button 12 may further include a dome 124 disposed between the bottom plate 1 and the keycap 122. In general, the dome 124 is typically made of a soft material such as rubber. Therefore, the dome 124 of the button 12 can be pressed and deformed in conjunction with the pressing of the key cap 122, thereby contacting the bottom plate 1 and electrically connecting the switch which is originally provided on the base plate 10 to be disconnected. Also shown in Figures 2A and 2B, an assembly opening 122c can be formed between the end of the chute structure 122a of the keycap 122 and the end of the baffle arm 122b. When the keycap 122 is assembled to the scissor support structure 12'', the sliding shaft 120c of the first link i2〇a can be engaged to the chute structure 122a through the assembly port 122c. Further, the assembly port 122c is in interference engagement with the slide shaft 120c of the first link 120a. That is, the diameter of the sliding axis i2〇c of the first link 120a is larger than the size of the assembly port 8 M405002 122c. In one embodiment, the diameter of the sliding shaft l2〇c of the first link 12〇a may be 0.7~0.75 mm. The size of the assembly port 122c may be 〇5 mm. Therefore, the sliding axis 丨20c of the first link 120a. The ratio between the diameter of the assembly port 12 and the size of the assembly port 12 may be from 1 to 4, and is not limited thereto, and may be elastically adjusted in accordance with design requirements or manufacturing constraints. It can be seen that, in the present embodiment, when the keycap 122 is assembled to the scissor-type support structure I20, the sliding shaft 12〇c of the first link 120a is to be connected to the chute through the assembly port 122c. The structure 122a, the sliding shaft 120c of the first link 12A must be simultaneously extruded to form the end of the chute structure 122a of the assembly port 12 and the end of the baffle arm 122b, so that the end of the chute structure 122 & The end portion is elastically deformed, and the assembly port 122c is enlarged to allow the sliding shaft 12〇c of the first link 12A to pass. The material of the key cap 122 is not particularly limited as long as the chute structure 122 & and the arm 122b are pressed by the sliding shaft 120c of the first link 120a, the amount of deformation required for the structure 122a and the arm i22b can be increased. The material can be used; θ # as shown in FIG. 2 , in this embodiment, when the button 12 is at the lowest pressing position, the sliding shaft 120 c of the first link 120 a just faces the chute structure 122 a and the arm 122 b The assembled port 122c is formed. In other words, when the keycap 122 is assembled to the scissor support structure 12, the second link 120b can be made by pressing the keycap 122 of the button 12 vertically to the scissors support structure 12 to the lowest pressing position. The fixed shaft i20d is engaged with the second pivoting structure 122g of the keycap 122, and at the same time, the sliding shaft 120c of the first link 12A is pressed through the assembly opening 122c to engage the sliding groove structure 122a of the keycap 122. Moreover, as shown in FIG. 2B, when the button 12 is placed at the lowest pressing position 9 M405002, most of the sliding shaft 120c of the first link 120a is located outside the chute structure 122a, but there is no need to worry about the sliding shaft 12〇c being disengaged. The chute structure 122& because the baffle arm i22b of the key towel s 122 prevents the sliding axis i2〇c from coming off the chute structure 122a. Therefore, compared to the prior art, the keycap 122 of the present embodiment can obtain k liters by using the strength of the shorter chute structure 122a' chute structure 122a, and the key cap 122 is assembled to the scissor type 丨 structure. During the process of 20, damage to the keycap 122 or the scissor support structure 120 can be effectively reduced. Please refer to Fig. 3, which is a partially enlarged view showing the keycap 122 in Fig. 2A. As shown in FIG. 3, in the present embodiment, in order to smoother the assembly of the keycap I" to the scissor-type support structure 120, the chute structure 122a of the keycap 122 may include the first portion at the assembly port 122c. A guiding surface 122d' and the blocking arm 122b of the keycap 122 may also include a second guiding surface 122f at the assembly opening 122c. Thereby, the first guiding surface 122d and the blocking arm 122b of the sliding slot structure 122a The two guiding surfaces 122f can guide the sliding shaft 120c when the sliding shaft 120c of the first connecting rod 120a passes through the assembling port 122c, so that the friction between the sliding shaft 120c and the sliding groove structure 122a and the blocking arm 122b is greatly reduced. The damage of the sliding shaft 120c, the chute structure 122a or the blocking arm 122b is effectively reduced. Also shown in Fig. 3, in the present embodiment, the sonar arm 122b of the keycap 122 may further include a hook portion 122e. In other words, The assembly port 122c is formed between the chute structure 122a of the keycap 122 and the hook portion 122e of the arm 122b, and the second guiding surface 122f is located on the hook portion i22e. The structure of the hook portion 122e of the arm 122b The design 'further strengthens the sliding groove 120c of the first link 120a from the sliding cap of the keycap 122 The function of constructing 22a and detaching from assembly M405002 σ 122c. From the above detailed description of the specific embodiment of the present invention, it is obvious that the key reading and its _, mainly for the cap, for the knife The structure of the sliding joint of the branch (four) structure is improved. When the key cap is pressed perpendicularly toward the sliding shaft by the assembly port between the sliding groove structure and the blocking arm, the sliding shaft can be elasticized by the structure of the sliding groove. The deformation passes through the wrap-out port and then engages with the chute structure. Therefore, the key cap of the present invention can be assembled only by a single step of being vertically pressed toward the scissor-type support structure, without having to press the key as before. The step of assembling the cap obliquely to the scissor support structure. And 'Because the key cap contains the shot, the length of the chute structure can be shortened, so that during the assembly of the key cap on the scissor support structure, Effectively reducing the damage of the keycap or the scissor support. Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and those skilled in the art, without departing from the spirit and scope of the present invention, The various modifications and refinements can be made, and therefore the scope of protection of this creation is subject to the definition of the patent application scope.
