如图1和图2所示,本发明实施例一提供一种触摸框组件,触摸框组件包括红外触摸框10、玻璃盖板20以及连接层30。其中,红外触摸框10包括框体11以及设置在框体11上的PCB组件,PCB组件包括PCB板121和发光件122,玻璃盖板20位于发光件122的内侧,发光件122可以发出红外信号。玻璃盖板20包括触摸表面,用户通过触摸表面可以进行触控操作。在本实施例中,框体11的外表面指的是框体11朝向玻璃盖板20一侧的表面,框体11的外表面具有凹陷面111,凹陷面111向内凹陷,在利用连接层30将玻璃盖板20固定在框体11上时,玻璃盖板20的内表面会贴设于凹陷面111,使得玻璃盖板20受力发生形变向内凹陷。As shown in FIG. 1 and FIG. 2 , Embodiment 1 of the present invention provides a touch frame assembly. The touch frame assembly includes an infrared touch frame 10 , a glass cover plate 20 and a connection layer 30 . The infrared touch frame 10 includes a frame body 11 and a PCB assembly disposed on the frame body 11. The PCB assembly includes a PCB board 121 and a light-emitting element 122. The glass cover 20 is located inside the light-emitting element 122, and the light-emitting element 122 can emit infrared signals. . The glass cover 20 includes a touch surface through which a user can perform touch operations. In this embodiment, the outer surface of the frame body 11 refers to the surface of the frame body 11 on the side facing the glass cover plate 20 . The outer surface of the frame body 11 has a recessed surface 111 , and the recessed surface 111 is recessed inward. 30 When the glass cover plate 20 is fixed on the frame body 11, the inner surface of the glass cover plate 20 is attached to the recessed surface 111, so that the glass cover plate 20 is deformed and dented inward by force.
应用本实施例提供的触摸框组件,当位于玻璃盖板20外侧的发光件122发出红外信号时,由于玻璃盖板20向内凹陷,内凹的玻璃盖板20不会阻挡红外信号输送,能够保证红外触控操作正常进行。此外,采用上述结构的显示设备只需在框体11的外表面加工凹陷面111,不需要通过挑选玻璃进行玻璃盖板20内凹管控,能够减少玻璃的损耗,可以提高生产效率,降低生产成本。Using the touch frame assembly provided in this embodiment, when the light-emitting element 122 located on the outer side of the glass cover plate 20 sends out an infrared signal, since the glass cover plate 20 is recessed inward, the recessed glass cover plate 20 will not block the transmission of the infrared signal, and can Ensure that the infrared touch operation is performed normally. In addition, the display device using the above structure only needs to process the concave surface 111 on the outer surface of the frame body 11, and does not need to select the glass for concave control of the glass cover plate 20, which can reduce the loss of glass, improve production efficiency, and reduce production costs. .
其中,发光件122发出红外信号时,可以在玻璃盖板20的上表面对应形成横竖交叉的红外线矩阵,当用户触摸玻璃盖板20时,控制器判断触点在玻璃盖板20上的具体位置,从而 完成红外触控操作。可以理解的是,触控表面可以是由红外线交叉形成的红外线矩阵,也可以是与该红外线矩阵对应的玻璃盖板的表面,在此不作限定。Wherein, when the light-emitting element 122 emits an infrared signal, a horizontal and vertical cross-infrared matrix can be formed on the upper surface of the glass cover 20. When the user touches the glass cover 20, the controller determines the specific position of the contact on the glass cover 20. to complete the infrared touch operation. It can be understood that, the touch surface may be an infrared matrix formed by intersecting infrared rays, or may be the surface of the glass cover corresponding to the infrared matrix, which is not limited herein.
需要说明的是,在本实施例中,将玻璃盖板20设置在凹陷面111的外侧,玻璃盖板20更靠近用户,能够有效降低书写高度,提升书写体验。It should be noted that, in this embodiment, the glass cover plate 20 is arranged outside the recessed surface 111 , and the glass cover plate 20 is closer to the user, which can effectively reduce the writing height and improve the writing experience.
如图2所示,在本实施例中,框体11厚度呈均匀变化,框体11的中部的厚度小于框体11的两端的厚度以形成凹陷面111。As shown in FIG. 2 , in this embodiment, the thickness of the frame body 11 changes uniformly, and the thickness of the middle of the frame body 11 is smaller than the thickness of both ends of the frame body 11 to form the concave surface 111 .
在本实施例中,框体11设置有用于与玻璃盖板20相配合的加工面,加工面为凹陷面111,该加工面可以通过机加工得到,凹陷面111可以为弧形凹面,也可以是断差面,能够使得加工面沿其两端向中部逐渐凹陷即可,玻璃盖板20的内表面贴设于凹陷面111,此时玻璃盖板20与凹陷面111相匹配或相贴合,使得玻璃盖板20向内凹陷,进而避免玻璃盖板20在使用过程中由于外凸而阻挡PCB组件发出的红外信号。如图1所示,图中箭头指向代表红外信号输送,此时玻璃盖板20内凹,信号正常输送,进而保证红外触控操作正常进行。In this embodiment, the frame body 11 is provided with a processing surface for matching with the glass cover plate 20 . The processing surface is a recessed surface 111 , which can be obtained by machining. The recessed surface 111 can be an arc-shaped concave surface, or can be It is a fracture surface, which can make the processing surface gradually concave to the middle along its two ends. The inner surface of the glass cover plate 20 is attached to the concave surface 111. At this time, the glass cover plate 20 matches or fits with the concave surface 111. , so that the glass cover plate 20 is recessed inward, thereby preventing the glass cover plate 20 from blocking the infrared signal emitted by the PCB assembly due to the outward protrusion during use. As shown in FIG. 1 , the arrow points in the figure represent infrared signal transmission. At this time, the glass cover plate 20 is concave, and the signal is transmitted normally, thereby ensuring the normal operation of the infrared touch operation.
在本实施例中,通过切削框体11的中部形成凹陷面111,从而使得框体11的凹陷面111加工更加方便。In this embodiment, the recessed surface 111 is formed by cutting the middle of the frame body 11 , so that the processing of the recessed surface 111 of the frame body 11 is more convenient.
具体地,凹陷面111为弧形凹面。采用弧形凹面的结构,便于利用弧形凹面使玻璃盖板20发生形变。Specifically, the concave surface 111 is an arc-shaped concave surface. The arc-shaped concave structure is adopted, which facilitates the use of the arc-shaped concave surface to deform the glass cover plate 20 .
在本实施例中,弧形凹面为对称结构,使得玻璃盖板20能够对称凹陷,进而保证玻璃盖板20的内凹更加稳定。In this embodiment, the arc-shaped concave surface has a symmetrical structure, so that the glass cover plate 20 can be symmetrically recessed, thereby ensuring that the inner concave of the glass cover plate 20 is more stable.
优选的是,弧形凹面的最高点与玻璃盖板20的两端相对应设置,弧形凹面的最低点与玻璃盖板20的长边的中点相对应设置,可以理解的是,弧形凹面的最高点也可以与框体11的两端相对应设置,弧形凹面的最低点与框体11的长边的中点相对应设置。Preferably, the highest point of the arc-shaped concave surface is set corresponding to both ends of the glass cover plate 20, and the lowest point of the arc-shaped concave surface is set corresponding to the midpoint of the long side of the glass cover plate 20. The highest point of the concave surface may also be set corresponding to both ends of the frame body 11 , and the lowest point of the arc-shaped concave surface may be set corresponding to the midpoint of the long side of the frame body 11 .
即弧形凹面的最高点为框体11的两端点或在玻璃盖板20的两端点附近,弧形凹面的最低点为框体11的中点或在玻璃盖板20的中点附近,使得玻璃盖板20能够实现均匀凹陷,避免玻璃盖板20因局部凹陷变形过大造成玻璃盖板20破裂,此外,玻璃盖板20的长边长度大于短边长度,容易使得玻璃盖板20从中部向内侧发生弯曲,从而实现玻璃盖板20内凹,此为可选方案。That is, the highest point of the arc-shaped concave surface is the two ends of the frame body 11 or near the two end points of the glass cover plate 20, and the lowest point of the arc-shaped concave surface is the midpoint of the frame body 11 or near the middle point of the glass cover plate 20, so that The glass cover plate 20 can be evenly dented, so as to avoid the glass cover plate 20 from being broken due to the excessive deformation of the partial depression. In addition, the length of the long side of the glass cover plate 20 is longer than the length of the short side, which is easy to make the glass cover plate 20 from the middle Bending inwards, so that the glass cover plate 20 is concave, which is an optional solution.
其中,弧形凹面的最高点与弧形凹面的最低点的高度差为H,H的取值范围为0.5mm-5mm。具体地,H可以为0.5mm、1mm、2mm、3mm、4mm、5mm以及0.5mm至5mm之间的其它任意数值。需要指出的是,当H值过小时,则使得玻璃盖板20的弯曲不够明显,此时由于玻璃盖板20因工艺原因导致玻璃盖板20本身的外凸,容易遮挡红外光线的传输,而当H值过大时则易导致玻璃盖板20发生断裂,故上述取值范围H值为可选方案。The height difference between the highest point of the arc-shaped concave surface and the lowest point of the arc-shaped concave surface is H, and the value range of H is 0.5mm-5mm. Specifically, H can be 0.5mm, 1mm, 2mm, 3mm, 4mm, 5mm and any other value between 0.5mm and 5mm. It should be pointed out that when the H value is too small, the bending of the glass cover plate 20 is not obvious enough. At this time, due to the process reasons, the glass cover plate 20 itself is convex, which is easy to block the transmission of infrared light, and When the H value is too large, the glass cover plate 20 is likely to be broken, so the above-mentioned value range H is an optional solution.
在本实施例中,玻璃盖板20的外轮廓为矩形,玻璃盖板20的长边与凹陷面111相配合,如此便于玻璃盖板20发生形变。In this embodiment, the outer contour of the glass cover plate 20 is a rectangle, and the long side of the glass cover plate 20 is matched with the concave surface 111 , which facilitates the deformation of the glass cover plate 20 .
如图1和图2所示,玻璃盖板20通过连接层30与凹陷面111相连接,由此将玻璃盖板20粘接在凹陷面111上,实现将玻璃盖板20固定在框体11上,进而保证玻璃盖板20向内弯曲,同时使得两者之间的连接结构更加紧凑,便于减薄设备的厚度尺寸,提升使用体验。As shown in FIG. 1 and FIG. 2 , the cover glass 20 is connected to the recessed surface 111 through the connecting layer 30 , so that the cover glass 20 is bonded to the recessed surface 111 , and the cover glass 20 is fixed on the frame body 11 . , thereby ensuring that the glass cover plate 20 is bent inward, and at the same time making the connection structure between the two more compact, which is convenient for reducing the thickness and size of the device and improving the use experience.
具体地,连接层30包括双面胶层或液体胶层,由此使得玻璃盖板20与凹陷面111之间的连接结构更加简单,且保证两者之间连接牢固。Specifically, the connection layer 30 includes a double-sided adhesive layer or a liquid adhesive layer, thereby making the connection structure between the glass cover plate 20 and the recessed surface 111 simpler and ensuring firm connection between the two.

It should be noted that, in this embodiment, the plane of the frame body 11 that is in contact with the inner surface of the glass cover plate 20 forms the step surface 1121 of the step 112 . The steps 112 on the frame body 11 form a sunken table structure, at least part of the glass cover plate 20 is sunk into the table surrounded by the steps 112 , and the inner surface of the glass cover plate 20 is in contact with the step surface 1121 of the step 112 In combination, the glass cover plate 20 is supported by the step surface 1121 , the side wall of the glass cover plate 20 is arranged corresponding to the step 112 , and the step 112 is used to support and limit the glass cover plate.
上述结构使得玻璃盖板20的安装更加方便且抵接更稳定。在将玻璃盖板20放入台阶112之后,利用连接层对玻璃盖板20进行固定,避免玻璃盖板20发生滑脱,且台阶112具有一个定位作用,便于玻璃盖板20的安装。其中,图1中玻璃盖板20的端部与台阶112之间具有间隔,由于各部件在加工过程中存在加工误差,通过设置该间隔,能够保证玻璃盖板20顺利装入框体11内。The above structure makes the installation of the glass cover plate 20 more convenient and the abutting more stable. After the glass cover plate 20 is put into the step 112 , the glass cover plate 20 is fixed by the connecting layer to avoid slippage of the glass cover plate 20 , and the step 112 has a positioning function to facilitate the installation of the glass cover plate 20 . There is a gap between the end of the glass cover 20 and the step 112 in FIG. 1 .
