[0039] The utility model can hide the component 3 in the bottom groove of the backlight plate 1 through the cooperation between the display cover plate and the groove part, so as to realize the insulation protection operation of the components of the display screen module. Specifically, the component structure formed by the combination of the component 3 and the PCB board is directly placed in the groove part, and then the display cover plate 4 is guided to be connected with the backlight plate 1. At this time, the display cover plate 4 fits with the opening of the groove part to form a closed cavity covering the component structure in the groove part. In this operation, not only the extra space for installing the component 3 and the PCB board is saved, but also the existence of the closed cavity realizes insulation protection.

[0040] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0041] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0042] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0043] Please refer to Figure 1-5 The element protection structure is arranged on the backlight panel 1, and is characterized in that the element protection structure comprises:

[0044] The groove portion is arranged on the surface of the backlight plate 1;

[0045] Component 3, which is arranged on the PCB board and combined with the PCB board to form a component structure, and the component structure is movably connected in the groove part;

[0046] A display cover plate 4 connected to the backlight plate 1;

[0047] When the display cover plate 4 is connected to the backlight plate 1 , the display cover plate 4 fits with the opening of the groove portion so that a closed cavity covering the component structure is formed in the groove portion.

[0048] The utility model can hide the component 3 in the bottom groove of the backlight plate 1 through the cooperation between the display cover plate and the groove part, so as to realize the insulation protection operation of the components of the display screen module. Specifically, the component structure formed by the combination of the component 3 and the PCB board is directly placed in the groove part, and then the display cover plate 4 is guided to be connected with the backlight plate 1. At this time, the display cover plate 4 fits with the opening of the groove part to form a closed cavity covering the component structure in the groove part. In this operation, not only the extra space for installing the component 3 and the PCB board is saved, but also the existence of the closed cavity realizes insulation protection.

[0049] Furthermore, the groove portion is a groove 2 arranged on the surface of the backlight plate 1 .

[0050] The groove portion can be an additional metal component installed on the backlight panel 1, or it can be a groove 2 set on the surface of the backlight panel 1. The subsequent method is the preferred method of this application, which can greatly reduce the volume of the device.

[0051] Furthermore, the groove width of the groove 2 is not less than the width of the component structure.

[0052] This arrangement is to ensure that the component structure can be fully placed in the groove 2.

[0053] Furthermore, a plurality of positioning posts 5 are disposed on the surface of the backlight plate 1 for fitting with the display cover plate 4 .

[0054] In order to prevent the backlight plate 1 and the display cover plate 4 from being misaligned during installation, it is preferred that a plurality of positioning posts 5 are used to cooperate with the display cover plate 4 so that the edge misalignment does not occur when the two are attached.

[0055] Furthermore, a plurality of buckles 6 are disposed on the edge of the groove portion; each of the buckles 6 can pass through the display cover plate 4 to fix the display cover plate 4 and the backlight plate 1 together.

[0056] After the lamination is completed, the backlight panel 1 and the display cover panel 4 need to be fixed. In order to speed up the fixing efficiency and further limit the position, specifically, multiple buckles 6 are passed through the display cover panel 4 to fix the display cover panel 4 and the backlight panel 1.

[0057] The component protection structure of the display screen module provided in Example 1 is further optimized. Furthermore, a sealing member is provided on the inner side of the groove portion to limit the component structure in the groove portion.

[0058] Due to the presence of the groove, the component structure is prone to shaking, resulting in damage to the edge of the component structure. Therefore, the component structure in the groove is limited by a sealing member.

[0059] The component protection structure of the display screen module provided in Embodiment 1 or 2 is further optimized. The component protection structure is arranged on the backlight plate 1, and is characterized in that the component protection structure comprises:

[0060] The groove portion is arranged on the surface of the backlight plate 1;

[0061] Component 3, which is arranged on the PCB board and combined with the PCB board to form a component structure, and the component structure is movably connected in the groove part;

[0062] A display cover plate 4 connected to the backlight plate 1;

[0063] When the display cover plate 4 is connected to the backlight plate 1 , the display cover plate 4 fits with the opening of the groove portion so that a closed cavity covering the component structure is formed in the groove portion.

[0064] The utility model can hide the component 3 in the bottom groove of the backlight plate 1 through the cooperation between the display cover plate and the groove part, so as to realize the insulation protection operation of the components of the display screen module. Specifically, the component structure formed by the combination of the component 3 and the PCB board is directly placed in the groove part, and then the display cover plate 4 is guided to be connected with the backlight plate 1. At this time, the display cover plate 4 fits with the opening of the groove part to form a closed cavity covering the component structure in the groove part. In this operation, not only the extra space for installing the component 3 and the PCB board is saved, but also the existence of the closed cavity realizes insulation protection.

[0065] Furthermore, the groove portion is a groove 2 arranged on the surface of the backlight panel 1. The groove portion can be an additional metal component installed on the backlight panel 1, or it can be a groove 2 arranged on the surface of the backlight panel 1. The subsequent method is the preferred method of this application, which can greatly reduce the volume of the device. The groove width of the groove 2 is not less than the width of the component structure. This arrangement is to allow the component structure to be fully placed in the groove 2. A plurality of positioning posts 5 are arranged on the surface of the backlight panel 1 to fit with the display cover panel 4. In order to prevent the backlight panel 1 and the display cover panel 4 from being misaligned during installation, it is preferred that a plurality of positioning posts 5 are used to cooperate with the display cover panel 4 so that there will be no edge misalignment when the two are fitted. A plurality of buckles 6 are arranged on the edge of the groove portion; each of the buckles 6 can pass through the display cover panel 4 to fix the display cover panel 4 and the backlight panel 1. After the lamination is completed, the backlight panel 1 and the display cover panel 4 need to be fixed. In order to speed up the fixing efficiency and further limit the position, specifically, a plurality of buckles 6 are passed through the display cover panel 4 to fix the display cover panel 4 and the backlight panel 1. Further, the closure member includes a pair of surrounding bars 7 arranged along the inner side of the groove portion, and the pair of surrounding bars 7 are combined to form a structure matching the groove portion, and each of the surrounding bars 7 is provided with an elastic member 8 between the inner side wall of the groove portion. Further, the surrounding bar 7 is provided with an inclined surface 9 on the side away from the bottom of the groove portion.

[0066] In order to solve the problem of damage to the edge of the component structure, the component 3 is restricted by the surrounding bar 7. Specifically, the component 3 is introduced into the groove portion by the guidance of the inclined surface 9, and then the elastic member 8 (a spring can be selected) presses the surrounding bar 7 against the edge of the component 3, so that the component 3 will not move at will.

[0067] The component protection structure of the display screen module provided in the above embodiments is further optimized. Furthermore, the sealing member includes an elastic ring 10 (a sponge pad or a rubber pad may be selected) matching the groove portion, and a limiting groove 11 matching the component structure is provided in the elastic ring 10.

[0068] Furthermore, the thickness of the elastic ring 10 is greater than the thickness of the groove portion.

[0069] Although the presence of the surrounding strip 7 can restrict the component 3, the component 3 is still easily crushed by the surrounding strip 7. In order to solve this problem, the component 3 can be restricted by the limiting groove 11 in the elastic ring 10. At the same time, when the display cover plate 4 and the backlight plate 1 are connected, the elastic ring 10 can block the gap between the display cover plate 4 and the backlight plate 1, thereby avoiding the collision of the display cover plate 4, and at the same time, foreign debris and moisture will not enter the gap.

[0070] The use process of the component protection structure of the display screen module provided by the utility model is as follows: the utility model can hide the component 3 in the bottom groove of the backlight plate 1 through the cooperation of the display cover plate and the groove part, so as to realize the insulation protection operation of the components of the display screen module. Specifically, the component structure formed by the combination of the component 3 and the PCB board is directly placed in the groove part, and then the display cover plate 4 is guided to be connected with the backlight plate 1. At this time, the display cover plate 4 is fitted with the opening of the groove part to form a closed cavity covering the component structure in the groove part. In this operation, not only the extra space for installing the component 3 and the PCB board is saved, but also the existence of the closed cavity realizes insulation protection.
