The display screen cover 10 includes a mask base 110, and the mask base 110 is provided with a plurality of a light hole 120, when the display screen cover 10 is assembled to the LED display module or the LED display screen, the LED light bead is exposed through the light hole 120 to be exposed to the display screen cover 10, the light hole 120 The side wall is provided with a latching member 130. The latching member 130 includes a first end 130a and a second end 130b disposed opposite to each other, and a line connecting the first end 130a and the second end 130b is opposite to the mask base. The plane in which the 110 is located is inclined, the first end 130a is fixedly connected to the mask substrate 110, the second end 130b is a free end, and the display screen cover 10 is mounted on the LED display module or the LED display screen. When it is resisted by the LED lamp bead, it forms a tight fit with the LED lamp bead, so that the display screen cover 10 can be fixed by the LED lamp bead.
在具体的实施例中,所述卡位件130与所述面罩基底110一体成型。为避免面罩对LED灯珠的损伤,所述卡位件130及所述面罩基底110均采用柔性材质制成,例如硅胶、塑胶、TPU或者其他的柔性材质。In a specific embodiment, the card member 130 is integrally formed with the mask substrate 110. In order to avoid damage to the LED lamp bead by the mask, the card member 130 and the mask substrate 110 are made of a flexible material such as silicone, plastic, TPU or other flexible materials.
在一个或多个实施例中,每个所述灯孔120内设置两个所述卡位件130,两个所述卡位件130相对设置,两个所述卡位件130的第二端130b之间的间距L1小于LED灯珠的宽度L2,每个所述卡位件130的宽度L3大于LED灯珠与显示屏面罩10之间的间隙L4,从而使得当所述显示屏面罩10装配于LED显示模组或LED显示屏上时,两个所述卡位件130的第二端130b均紧密的抵住LED灯珠,并利用所述卡位件130与LED灯珠之间的摩擦力来阻止显示屏面罩10从LED显示模组或LED显示屏上脱落。本领域技术人员可以理解的是,也可以设置三个或四个或更多个卡位件130。In the one or more embodiments, two of the latching members 130 are disposed in each of the lamp holes 120, and the two latching members 130 are oppositely disposed, and the second ends of the two latching members 130 are oppositely disposed. The spacing L1 between 130b is smaller than the width L2 of the LED bead, and the width L3 of each of the clamping members 130 is greater than the gap L4 between the LED bead and the display mask 10, so that when the display mask 10 is assembled When the LED display module or the LED display screen is used, the second ends 130b of the two latching members 130 are closely pressed against the LED lamp bead, and the friction between the latching member 130 and the LED lamp bead is utilized. Force to prevent the display mask 10 from falling off the LED display module or LED display. Those skilled in the art will appreciate that three or four or more card members 130 may also be provided.
在一些实施例中,所述卡位件130包括平部131及斜部133,所述平部131固定连接于所述面罩基底110,所述斜部133固定连接于所述平部131,且所述斜部133相对所述平部131向远离所述面罩基底110的装配面的方向倾斜。所谓面罩基底110的装配面即当显示屏面罩10装配于LED显示模组或LED显示屏上时,面罩基底110的靠近LED显示模组或LED显示屏的端面。In some embodiments, the latching member 130 includes a flat portion 131 and a sloped portion 133, the flat portion 131 is fixedly coupled to the mask base 110, and the inclined portion 133 is fixedly coupled to the flat portion 131, and The inclined portion 133 is inclined with respect to the flat portion 131 in a direction away from the fitting surface of the mask base 110. The assembly surface of the mask substrate 110 is the end surface of the mask substrate 110 near the LED display module or the LED display screen when the display screen cover 10 is mounted on the LED display module or the LED display screen.
当所述显示屏面罩10装配于LED显示模组或LED显示屏上时,所述平部131对LED灯珠具有间接作用的水平方向的挤压力,所述斜部133对LED灯珠具有水平方向的挤压力及垂直方向的摩擦力,在水平方向的挤压力和垂直方向的摩擦力的作用下,显示屏面罩10被固定于LED灯珠上。本领域技术人员可以理解的是,所述水平方向及垂直方向仅针对图2中的方向相对而言。When the display screen cover 10 is mounted on the LED display module or the LED display screen, the flat portion 131 has an indirect horizontal pressing force on the LED lamp bead, and the inclined portion 133 has an LED lamp bead on the LED lamp bead. The pressing force in the horizontal direction and the frictional force in the vertical direction are fixed to the LED lamp bead by the horizontal pressing force and the vertical frictional force. It will be understood by those skilled in the art that the horizontal and vertical directions are only relative to the direction in FIG.
通过在灯孔120的侧壁设置卡位件130,利用卡位件130与LED灯珠之间的挤压力和摩擦力,使得所述面罩可以通过LED灯珠进行固定,同时可以防止面罩与LED灯珠相脱离。LED显示屏安装于户外,并被太阳光高强度照射时,由于密封的环境及LED显示模组的光反射,位于显示屏面罩10与LED显示模组之间的空气的温度相比外界的空气温度较高,因而使得显示屏面罩10具有膨胀变形的趋势,在热膨胀的内应力作用下显示屏面罩10具有脱离LED显示模组的趋势。卡位件130与LED灯珠之间的挤压力和摩擦力能够阻止显示屏面罩10脱离LED显示模组的趋势,由于LED灯珠的密集性,显示屏面罩10在每个LED灯珠处均存在卡位件130与LED灯珠的摩擦力,因而显示屏面罩10不会因受到高温而发生鼓包的现象。By providing the latching member 130 on the side wall of the lamp hole 120, the pressing force and friction between the latching member 130 and the LED lamp bead are utilized, so that the mask can be fixed by the LED lamp bead, and the mask can be prevented. The LED lamp beads are separated. When the LED display is installed outdoors and is exposed to high intensity by sunlight, the temperature of the air between the display mask 10 and the LED display module is higher than the outside air due to the sealed environment and the light reflection of the LED display module. The higher temperature causes the display screen cover 10 to have a tendency to expand and deform, and the display screen cover 10 has a tendency to detach from the LED display module under the action of thermal expansion internal stress. The pressing force and friction between the clamping member 130 and the LED lamp bead can prevent the display mask 10 from moving away from the LED display module. Due to the density of the LED bead, the display mask 10 is at each LED bead. There is friction between the card member 130 and the LED lamp bead, and thus the display screen cover 10 does not suffer from bulging due to high temperature.
在一个或多个实施例中,为了强化卡位件130与LED灯珠之间的摩擦力,防止显示屏面罩10与LED灯珠的脱离,所述斜部133由热塑性材质制成,常温下,所述斜部133为柔性材质,随着温度的升高超过预设值,所述斜部133能够完全软化,从而所述斜部133与LED灯珠接触的部分能够贴合于LED灯珠上,从而在斜部133与LED灯珠之间产生吸附力,达到强化摩擦力的目的。进一步,可以于所述斜部133的靠近灯珠的一侧设置多个摩擦凸起(图未示),以增强摩擦力。In one or more embodiments, in order to strengthen the friction between the card member 130 and the LED lamp bead, the detachment of the display screen cover 10 from the LED lamp bead is prevented, and the inclined portion 133 is made of a thermoplastic material at normal temperature. The inclined portion 133 is a flexible material, and the inclined portion 133 can be completely softened as the temperature rises beyond a preset value, so that the portion of the inclined portion 133 that is in contact with the LED lamp bead can be attached to the LED lamp bead. Therefore, an adsorption force is generated between the inclined portion 133 and the LED lamp bead to achieve the purpose of enhancing the friction. Further, a plurality of friction protrusions (not shown) may be disposed on a side of the inclined portion 133 close to the lamp bead to enhance friction.

Specifically, when the latching member 130 is not provided with the flat portion 131 and only the inclined portion 133 is disposed, after the display screen cover 10 is mounted on the LED display module or the LED display screen, the inclined portion 133 and the mask are The plane in which the substrate 110 is located has an angle of 15° to 20°. When the latching member 130 is provided with the flat portion 131 and the inclined portion 133, the line connecting the ends of the flat portion 131 and the inclined portion 133 away from each other is 15° with the plane of the mask base 110. ~20 ° angle. The angle between the line connecting the first end 130a and the second end 130b and the plane of the mask substrate 110 is set to 15°-20°, so that the display screen cover 10 can pass the card member 130 and the LED lamp.

将面罩240套入所述环形凹槽255内时,首先将所述倒扣针250的头部251对准固定孔241,此时,由于第三部分2515的截面宽度大于固定孔241的直径,因此面罩240不能套入第三部分2515,在外力的作用下,第三部分2515穿入固定孔241内,面罩240发送形变而套设于所述第三部分2513外缘,在外力的持续作用下,面罩240沿着第三部分2515进入到所述环形凹槽255内,套设于所述第二部分2513的外缘,即将面罩240与所述倒扣针250完成固定,此时卡位件与LED灯珠230之间形成紧配合。在上述面罩240固定的过程中,倒扣针250对于面罩240产生一个阻止力,外力的直接作用对象也为面罩240,也即在面罩240的固定过程中,PCB板220不会被直接受力,相比采用螺钉固定面罩240的方式,由于螺钉下拧的过程中,对PCB板220产生持续作用力,并且下拧过程中,一旦螺钉错位,就可能损伤LED灯珠230,通过倒扣针250固定面罩240的方式,可以避免面罩240装配过程中对灯珠的损伤,外力作用于面罩240时,可以对应LED的间隙处施力,并且单纯的下压力也比旋转力更便于控制。在一些实施例中,为了便于面罩240与倒扣针250的定位,所述第三部分2515远离所述环形凹槽255的一端设置有斜面。When the mask 240 is inserted into the annular groove 255, the head 251 of the inverted pin 250 is first aligned with the fixing hole 241. At this time, since the cross-sectional width of the third portion 2515 is larger than the diameter of the fixing hole 241, Therefore, the mask 240 cannot be inserted into the third portion 2515. Under the action of the external force, the third portion 2515 penetrates into the fixing hole 241, and the mask 240 transmits deformation and is sleeved on the outer edge of the third portion 2513, and the external force continues. The mask 240 enters the annular groove 255 along the third portion 2515 and is sleeved on the outer edge of the second portion 2513, that is, the mask 240 and the inverted pin 250 are fixed. A tight fit is formed between the piece and the LED bead 230. During the fixing process of the mask 240, the inverted pin 250 generates a blocking force for the mask 240, and the direct acting object of the external force is also the mask 240, that is, during the fixing process of the mask 240, the PCB board 220 is not directly stressed. Compared with the way of fixing the mask 240 by screws, since the screw is screwed down, a continuous force is generated on the PCB board 220, and during the screwing process, once the screw is misaligned, the LED lamp bead 230 may be damaged, and the pin is broken. 250 fixing the mask 240 can avoid damage to the lamp bead during the assembly process of the mask 240. When the external force acts on the mask 240, the force can be applied corresponding to the gap of the LED, and the simple downforce is more convenient to control than the rotational force. In some embodiments, in order to facilitate the positioning of the mask 240 and the inverted pin 250, the third portion 2515 is provided with a slope at an end away from the annular groove 255.
在具体的实施例中,所述PCB板220的背离所述LED灯珠230的一侧于所述穿孔的周边设置有焊盘221,所述尾部253焊接于所述焊盘221,从而使所述倒扣针250固定于所述PCB板220上。In a specific embodiment, a side of the PCB board 220 facing away from the LED lamp bead 230 is provided with a pad 221 at a periphery of the through hole, and the tail portion 253 is soldered to the pad 221, thereby The inverted pin 250 is fixed to the PCB board 220.
在具体的实施例中,所述倒扣针250由不锈钢材质制成,在具有较强刚度的同时,又不易生锈。进一步,为了减少倒扣针250与面罩240之间的摩擦力,所述倒扣针250的表面还可以进行镀镍处理。In a specific embodiment, the inverted pin 250 is made of stainless steel, and has strong rigidity and is not easy to rust. Further, in order to reduce the friction between the inverted pin 250 and the mask 240, the surface of the inverted pin 250 may also be subjected to a nickel plating treatment.
在一些实施例中,所述LED显示模组20还包括灌封胶层260,所述灌封胶层260设置于所述PCB板220上,所述LED灯珠230至少部分外露于所述灌封胶层260。通过设置灌封胶层260,可以避免水分进入到PCB板220上,增强了LED显示模组20的防水性能。In some embodiments, the LED display module 20 further includes a potting layer 260. The potting layer 260 is disposed on the PCB board 220, and the LED lamp bead 230 is at least partially exposed to the filling. Sealing layer 260.
