In the application.
技术领域Technical field
本申请涉及到电子设备技术领域，尤其涉及到一种按键组件、键盘及移动终端。The present application relates to the field of electronic device technologies, and in particular, to a button component, a keyboard, and a mobile terminal.
背景技术Background technique
随着软、硬件技术的飞速发展，电子设备的性能越来越高，但是体积越做越小，不可否认轻薄化已是电子设备的一种发展趋势。尤其是需要携带的电子设备，比如笔记本在可携带型、续航、重量等方面都提出了很高的要求。With the rapid development of software and hardware technology, the performance of electronic devices is getting higher and higher, but the volume is getting smaller and smaller. It is undeniable that thinning and thinning has become a development trend of electronic devices. In particular, electronic devices that need to be carried, such as notebooks, have high requirements in terms of portability, battery life, weight, and the like.
目前市场上应用的按键较多的是剪刀脚+硅胶帽结构。该按键包含有：键帽、剪刀脚、硅胶帽、基板和电路板等部件组成。键帽通过剪刀脚安装在基板上。剪刀脚结构的张开和闭合可控制键帽的运动方向和位移，置于键帽下方的硅胶帽提供按键的回弹力，使按键一直保持升起的状态。At present, the keys used in the market are more scissors feet + silicone cap structure. The button consists of a key cap, a scissor foot, a silicone cap, a base plate, and a circuit board. The key cap is mounted on the substrate through the scissor foot. The opening and closing of the scissor foot structure can control the movement direction and displacement of the key cap, and the silicone cap placed under the key cap provides the resilience of the button, so that the button is always raised.
由于硅胶帽一直提供键帽的升力，在没有受到外力作用的时候键帽不会下沉，尤其是在笔记本扣合以后键帽一般会与显示屏中留出一定的间隙以保护屏幕。现有方案中这两个部分的空间是不能充分利用的，而且凸出的按键还有可能碰到屏幕。Since the silicone cap always provides the lift of the keycap, the keycap does not sink when there is no external force, especially after the notebook is fastened, the keycap generally leaves a certain gap with the display to protect the screen. The space in these two parts of the existing solution is not fully utilized, and the protruding buttons may also touch the screen.

When the keycap 70 is pressed, the first bracket 51 and the second bracket 52 can be rotated relative to the keycap 70 and the substrate 10, respectively, and the first bracket 51 and the second bracket 52 are also relatively rotated, thereby changing the height of the lifting bracket and implementing the key. The height of the cap 70 is changed when pressed, and Moreover, since one ends of the first bracket 51 and the second bracket 52 are respectively hinged with the keycap 70 and the base plate 10, when the keycap 70 is pressed, the keycap 70 can change in height in a set direction.
本实施例中的驱动及锁定组件包含两部分，分别为第一磁性件62及第一磁性吸附件61，第一磁性吸附件61可以被第一磁性件62吸附。其中的第一磁性件62为磁铁，第一磁性吸附件61可以为现有技术中常见的铁、钴、镍等能被磁铁吸附的材料制备而成，该第一磁性吸附件61可以根据需要设置成不同的形状如框形，即如图1所示中的结构，此时，第一磁性吸附件61为一个折弯的框形，且框形的顶端具有一个开口，该开口的两侧作为转轴与键帽70连接。在具体设置时，第一磁性件62与滑板30固定连接；第一磁性吸附件61的第一端与键帽70铰接，第二端抵压在基板10上并可相对基板10滑动；在基板10上设置了电路板20时，第一磁性吸附件61抵压在电路板20上，对于第一磁性吸附件61的设置应当注意的时，该第一磁性吸附件61在介于基板10与键帽70之间时，无论键帽70处于自由状态或者被按压状态时，第一磁性吸附件61均为倾斜设置，具体的，如图2及图3所示，以图2及图3中按键组件的放置方向为参考方向，第一磁性吸附件61相对于竖直方向倾斜。该第一磁性件62设置时，位于第一磁性吸附件61倾斜方向朝向的一方。此外，本实施例提供的第一磁性吸附件61与键帽70连接的一端受到的磁力应当小于第一磁性吸附件61抵压在基板10上的一端受到的磁力，由于第一磁性件62产生的磁场大小不会改变，因此，在具体设置时，第一磁性件62两端的金属含量应当不同，具体的，与键帽70铰接的第一端的金属含量小于抵压在基板10上的第二端的金属含量。在一个具体的方式中，第一磁性吸附件61可以包含一个塑料框架40，但塑料框架40抵压在基板10的一端设置了铁块。The driving and locking assembly in this embodiment comprises two parts, a first magnetic member 62 and a first magnetic adsorbing member 61, respectively, and the first magnetic adsorbing member 61 can be adsorbed by the first magnetic member 62. The first magnetic member 62 is made of a magnet, and the first magnetic adsorbing member 61 can be prepared by using a material such as iron, cobalt or nickel which can be adsorbed by the magnet. The first magnetic adsorbing member 61 can be as needed. It is arranged in a different shape such as a frame shape, that is, the structure as shown in FIG. 1. At this time, the first magnetic adsorbing member 61 has a bent frame shape, and the top end of the frame shape has an opening, and both sides of the opening It is connected to the keycap 70 as a rotating shaft. In a specific arrangement, the first magnetic member 62 is fixedly coupled to the slider 30; the first end of the first magnetic adsorbing member 61 is hinged to the key cap 70, and the second end is pressed against the substrate 10 and slidable relative to the substrate 10; When the circuit board 20 is disposed on the 10, the first magnetic adsorbing member 61 is pressed against the circuit board 20. When the setting of the first magnetic adsorbing member 61 is noted, the first magnetic adsorbing member 61 is interposed between the substrate 10 and When the keycaps 70 are in between, the first magnetic adsorbing members 61 are inclined when the keycap 70 is in a free state or in a pressed state, specifically, as shown in FIG. 2 and FIG. 3, in FIG. 2 and FIG. The direction in which the button assembly is placed is the reference direction, and the first magnetic adsorbing member 61 is inclined with respect to the vertical direction. When the first magnetic member 62 is disposed, it is located at one side in which the first magnetic adsorbing member 61 is inclined. In addition, the magnetic force received by one end of the first magnetic adsorbing member 61 and the key cap 70 provided by the embodiment should be less than the magnetic force received by the first magnetic adsorbing member 61 against the end of the substrate 10, due to the first magnetic member 62. The size of the magnetic field does not change. Therefore, the metal content at both ends of the first magnetic member 62 should be different in a specific setting. Specifically, the metal content of the first end hinged to the key cap 70 is smaller than the pressure on the substrate 10. The metal content of the two ends. In a specific manner, the first magnetic adsorbing member 61 may include a plastic frame 40, but the plastic frame 40 is pressed against an end of the substrate 10 to provide an iron block.
本实施例提供的滑板30可以相对基板10滑动，如图1所示，该滑板30中间具有镂空结构，升降支架可穿过该镂空结构，且在升降支架运动时，不受滑板30的限定。为了保证滑板30的滑动稳定性，本实施例提供了一个框架40，继续参考图1，该框架40上设置有用于升降支架穿过的通孔；在组装时，升降支架穿过该通孔后与键帽70连接，框架40与基板10固定连接，滑板30滑动装配在该框架40上。The sliding plate 30 provided in this embodiment can slide relative to the substrate 10. As shown in FIG. 1, the sliding plate 30 has a hollow structure in the middle, and the lifting bracket can pass through the hollow structure, and is not limited by the sliding plate 30 when the lifting bracket moves. In order to ensure the sliding stability of the sliding plate 30, the present embodiment provides a frame 40. With continued reference to FIG. 1, the frame 40 is provided with a through hole for the lifting bracket to pass through; when assembling, the lifting bracket passes through the through hole. Connected to the keycap 70, the frame 40 is fixedly coupled to the substrate 10, and the slider 30 is slidably mounted on the frame 40.
为了方便理解本实施例提供的升降组件50，下面结合图2～图4所示的结构详细说明该按键组件的工作原理。In order to facilitate the understanding of the lifting assembly 50 provided by the embodiment, the working principle of the button assembly will be described in detail below with reference to the structures shown in FIGS. 2 to 4.
首先参考图2，图2示出了键帽70处于自由状态时的结构示意图。由图2可以看出，第一磁性吸附件61处于倾斜状态，此时滑板30滑动到第一设定位置，该第一设定位置为使得第一磁性件62位于第一磁性吸附件61与键帽70铰接的处的竖直下方；第一磁性件62位于第一磁性吸附件61倾斜的一侧，在第一磁性件62的吸附下，第一磁性吸附件61发生转动(逆时针转动)，即第一磁性吸附件61的倾斜角度变小，并带动第一磁性吸附件61转动给键帽70提供支撑力，此时，第一磁性件62与所述第一磁性吸附件61的第二端吸合，使键帽70升起；如图3所示，当外力按压键帽70时，外力克服第一磁性吸附件61与第一磁性件62之间的磁力，第一磁性吸附件61发生转动(顺时针转动)，如图3所示，第一磁性件62与第一磁性吸附件61之间的距离增大，变为△，键帽70被按下，当外力消失时，第一磁性件62吸附第一磁性吸附件61，使得第一磁性吸附件61发生转动(逆时针转动)，推动键帽70回复到图2中所示的位置。Referring first to Figure 2, Figure 2 shows a schematic structural view of the keycap 70 in a free state. As can be seen from FIG. 2, the first magnetic adsorbing member 61 is in an inclined state, at which time the sliding plate 30 is slid to a first set position, such that the first magnetic member 62 is located at the first magnetic adsorbing member 61 and The first magnetic member 62 is located on the inclined side of the first magnetic adsorbing member 61. Under the adsorption of the first magnetic member 62, the first magnetic adsorbing member 61 rotates (counterclockwise rotation). That is, the inclination angle of the first magnetic adsorbing member 61 becomes small, and the rotation of the first magnetic adsorbing member 61 is provided to provide a supporting force to the keycap 70. At this time, the first magnetic member 62 and the first magnetic adsorbing member 61 The second end is sucked to raise the keycap 70; as shown in FIG. 3, when the external force presses the keycap 70, the external force overcomes the magnetic force between the first magnetic adsorbing member 61 and the first magnetic member 62, and the first magnetic attraction The member 61 rotates (clockwise rotation). As shown in FIG. 3, the distance between the first magnetic member 62 and the first magnetic adsorbing member 61 increases, becomes Δ, and the key cap 70 is pressed, when the external force disappears. The first magnetic member 62 adsorbs the first magnetic adsorbing member 61 so that the first magnetic adsorbing member 61 rotates (reverse When the hour hand is rotated, the push key cap 70 is returned to the position shown in FIG. 2.
在键帽70需要被锁定时，如图4所示，滑动滑板30，使得滑板30由第一设定位 置滑动到第二设定位置，从而改变第一磁性件62的位置，第一磁性件62带动第一磁性吸附件61朝向靠近键帽70的方向转动，第一磁性件62推动第一磁性吸附件61转动(顺时针转动)，第一磁性吸附件61与基板10的夹角变小，此时，第一磁性吸附件61带动键帽70下沉，当滑板30锁定时，第一磁性件62的位置锁定，即键帽70被锁定。When the keycap 70 needs to be locked, as shown in FIG. 4, the slider 30 is slid so that the slider 30 is set by the first setting. Sliding to the second set position, thereby changing the position of the first magnetic member 62, the first magnetic member 62 drives the first magnetic adsorbing member 61 to rotate toward the keycap 70, and the first magnetic member 62 pushes the first magnetic attraction When the member 61 rotates (clockwise rotation), the angle between the first magnetic adsorbing member 61 and the substrate 10 becomes smaller. At this time, the first magnetic adsorbing member 61 drives the keycap 70 to sink, and when the sliding plate 30 is locked, the first magnetic member The position of 62 is locked, that is, the keycap 70 is locked.
应当理解的是，上述描述的顺时针转动及逆时针转动是以图2中所示的第一磁性吸附件61的倾斜方向所定的，当第一磁性吸附件61的倾斜方向发生改变时，上述转动的方向也对应发生变化。It should be understood that the clockwise rotation and the counterclockwise rotation described above are determined by the inclination direction of the first magnetic adsorbing member 61 shown in FIG. 2, when the inclination direction of the first magnetic adsorbing member 61 is changed, The direction of rotation also changes accordingly.
此外，在上述实施例中，滑板30在滑动及锁定时，可以采用不同的结构来实现，以笔记本电脑为例，该滑板30滑动的驱动件可以为屏幕的转轴，在屏幕转动到打开位置时，滑板30滑动到第一设定位置并锁定，在屏幕转动到闭合位置时，滑板30滑动到第二设定位置并锁定；或者采用在键盘上设置一个扳动开关，在扳到第一位置时，滑板30滑动并锁定到第一设定位置，在扳到第二位置时，滑板30滑动并锁定到第二设定位置。In addition, in the above embodiment, the sliding plate 30 can be realized by different structures when sliding and locking. For example, in the notebook computer, the sliding member of the sliding plate 30 can be the rotating shaft of the screen, when the screen is rotated to the open position. The slide 30 slides to the first set position and is locked. When the screen is rotated to the closed position, the slide 30 slides to the second set position and is locked; or a toggle switch is set on the keyboard to move to the first position. When the slider 30 slides and locks to the first set position, the slider 30 slides and locks to the second set position when the second position is pulled.
通过上述描述可以看出，在本实施例中，通过驱动及锁定组件实现对键帽70的位置控制，在驱动及锁定组件位于驱动工作位时，可以给键帽70提供上升力，使得键帽70可以正常使用，在按压下后，通过提升力回复到初始位置；在驱动及锁定组件处于锁定位时，可以拉动键帽70下沉到键帽70被按压下时的位置，并将键帽70锁定，此时，整个键盘的高度可以降低，从而便于键盘的薄型化，进而便于整个移动终端的薄型化。As can be seen from the above description, in the present embodiment, the position control of the keycap 70 is realized by the driving and locking assembly, and when the driving and locking assembly is located at the driving working position, the lifting force can be provided to the keycap 70, so that the keycap 70 can be used normally, after pressing down, returning to the initial position by the lifting force; when the driving and locking assembly is in the locking position, the keycap 70 can be pulled down to the position when the keycap 70 is pressed down, and the keycap is 70 lock, at this time, the height of the entire keyboard can be reduced, thereby facilitating the thinning of the keyboard, thereby facilitating the thinning of the entire mobile terminal.
应当理解的是，磁性吸附件的设置位置不仅限定与上述图2的设定位置，还可以采用其他的设定位置。作为本实施例的一个变形。该驱动及锁定组件包括：固定在滑板30上的第四磁性件，固定在第一支架51上与基板10铰接的一端的第三磁性吸附件，在具体设置时，第一支架51上设置有凹槽，第三磁性吸附件固定在凹槽内；该第四磁性件的设置方式及结构与第一磁性件62相同；第三磁性吸附件与第一磁性吸附件61相同，唯一的区别在于第四磁性吸附件固定在第一支架51上，在具体使用时，滑板30滑动到第一设定位置时，第四磁性件位于第一支架51的第一侧并吸附第三磁性吸附件，带动第一支架51转动给键帽70提供支撑力；在滑板30滑动到第二设定位置时，第四磁性件位于第一支架51的另一侧并吸附第三磁性吸附件，将键帽70锁定在被按压时的位置。在该具体的驱动及锁定组件中，通过调整第四磁性件处于第一支架51的不同侧，即处于第三磁性吸附件的不同侧实现控制键帽70上升，以及锁定键帽70的功能。It should be understood that the position at which the magnetic adsorbing member is disposed is not limited to the set position of FIG. 2 described above, and other set positions may be employed. As a variation of this embodiment. The driving and locking assembly includes: a fourth magnetic member fixed on the sliding plate 30, and a third magnetic absorbing member fixed to one end of the first bracket 51 and hinged to the substrate 10. In a specific arrangement, the first bracket 51 is disposed on the first bracket 51. a recess, the third magnetic adsorbing member is fixed in the recess; the fourth magnetic member is disposed in the same manner and structure as the first magnetic member 62; the third magnetic adsorbing member is identical to the first magnetic adsorbing member 61, the only difference being that The fourth magnetic adsorbing member is fixed on the first bracket 51. When the sliding plate 30 slides to the first set position, the fourth magnetic member is located on the first side of the first bracket 51 and adsorbs the third magnetic adsorbing member. Driving the first bracket 51 to rotate provides a supporting force to the keycap 70; when the sliding plate 30 slides to the second set position, the fourth magnetic member is located on the other side of the first bracket 51 and adsorbs the third magnetic adsorbing member, and the keycap 70 is locked at the position when pressed. In this particular drive and lock assembly, the control keycap 70 is raised and the function of the keycap 70 is locked by adjusting the fourth magnetic member on different sides of the first bracket 51, i.e., on different sides of the third magnetic adsorbing member.

The keycap 70 is raised by the repulsive force between the member 64 and the third magnetic member 63.
如图8所示，滑板30滑动到第二设定位置时，第三磁性件63靠近第二磁性吸附件，远离第二磁性件64，此时，第三磁性件63与第二磁性件64之间的排斥力小于第三磁性件63对第二磁性吸附件的吸附力，通过第三磁性件63与第二磁性吸附件之间的吸附力，键帽70被锁定在被按压时的位置。As shown in FIG. 8, when the slider 30 slides to the second set position, the third magnetic member 63 is adjacent to the second magnetic adsorbing member, away from the second magnetic member 64. At this time, the third magnetic member 63 and the second magnetic member 64 are The repulsive force between them is smaller than the adsorption force of the third magnetic member 63 to the second magnetic adsorbing member, and the keycap 70 is locked at the position when pressed by the adsorption force between the third magnetic member 63 and the second magnetic adsorbing member. .
为了简化整个装置的结构，在一个具体的实施例中，滑板30为磁性吸附材料制作的板状结构，第二磁性吸附件与滑板30为一体结构。即此时，滑板30即为第二磁性吸附件，从而简化了整个装置的结构。In order to simplify the structure of the entire apparatus, in a specific embodiment, the slider 30 is a plate-like structure made of a magnetic adsorbent material, and the second magnetic adsorbing member is integrally formed with the slider 30. That is, at this time, the slider 30 is the second magnetic adsorbing member, thereby simplifying the structure of the entire apparatus.
通过上述描述可以看出，在本实施方案中，通过调整第二磁性件64的位置，实现第二磁性件64与第三磁性件63排斥时，提供键帽70上升的力，第二磁性件64与第二磁性吸附件吸附时，将键帽70锁定在被按压的位置。As can be seen from the above description, in the present embodiment, when the second magnetic member 64 and the third magnetic member 63 are repelled by adjusting the position of the second magnetic member 64, the force of the rise of the keycap 70 is provided, and the second magnetic member is provided. When the second magnetic adsorbing member is attracted to the second magnetic adsorbing member, the keycap 70 is locked in the pressed position.
