DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] As attached Figure 1 To Attachment Figure 5As shown: A display assembly structure includes a display body 1, a sealing frame 2 and a back cover 3, the sealing frame 2 is embedded between the display body 1 and the back cover 3, the back cover 3 is fixedly connected to the back of the display body 1, and the installation gap between the display body 1 and the back cover 3 is sealed by the sealing frame 2, thereby improving the sealing effect between the display body 1 and the back cover 3.

[0025] It should be understood that the above-mentioned fixed connection means that there is no relative movement between the two. There are many ways of fixed connection. Bolts can be used here to fix it so that the back cover 3 can be removed from the back of the display body 1 later, making it more convenient to inspect and maintain the inside of the display body 1.

[0026] Limiting grooves 201 corresponding to the display body 1 and the back cover 3 are opened on both sides of the sealing frame 2. The connection between the display body 1 and the back cover 3 is embedded in the limiting grooves 201, so that after the display body 1 and the back cover 3 are installed to each other, the gap between the display body 1 and the back cover 3 will be sealed by the sealing frame 2.

[0027] Among them, an installation cavity 301 is opened between the display body 1 and the back cover 3, and positioning grooves 5 are opened on both sides of the installation cavity 301 and are respectively located in the display body 1 and the back cover 3. The light guide plate 4 is clamped in the positioning groove 5 located in the display body 1, so that when the light guide plate 4 is installed in the display body 1, it is positioned by the positioning groove 5 to prevent the light guide plate 4 from being offset during installation. A back plate 401 located in the installation cavity 301 is installed on the side of the light guide plate 4, and is fixed by installing the back plate 401 in the installation cavity 301.

[0028] Guide grooves 601 are provided on the side walls between the display body 1 and the back cover 3, and a card plate 6 corresponding to the guide groove 601 is fixedly connected to the side wall through the limiting groove 201, so that when the sealing frame 2 is embedded between the display body 1 and the back cover 3 for installation and fixation, the card plate 6 will be inserted into the guide groove 601 for limiting, thereby improving the stability between the display body 1 and the back cover 3 after installation. Example

[0029] As attached Figure 1 To Attachment Figure 5 As shown: the display body 1 and the back cover 3 are snapped into the limiting groove 201, thereby making the connection between the display body 1 and the back cover 3 more convenient, and the display body 1 and the back cover 3 are not prone to deviation when connected.

[0030] As attached Figure 1 To Attachment Figure 5As shown: a positioning plate 402 is fixedly connected to the side of the back plate 401 away from the light guide plate 4, and the positioning plate 402 is clamped in the positioning groove 5 inside the back cover 3 to be fixed, so that the back plate 401 is installed in the installation cavity 301 with better stability.

[0031] Among them, a positioning silicone 501 is connected between the light guide plate 4 and the positioning groove 5, so that when the light guide plate 4 is installed in the positioning groove 5 and limited, the positioning silicone 501 can play a positioning role for the light guide plate 4, thereby preventing the light guide plate 4 from being easily offset during installation, thereby improving the installation efficiency. In the prior art, the X / Y direction positioning of the light guide plate 4 mainly relies on the top angle position silicone positioning, and there are many ways to install the positioning silicone 501, among which manual bonding and machine spraying are more widely used.

[0032] As attached Figure 1 To Attachment Figure 5 As shown: the card plate 6 and the guide groove 601 are both arranged in a rectangular shape, so that when the sealing frame 2 is installed between the display body 1 and the back cover 3, the card plates 6 connected on both sides of the sealing frame 2 will be inserted into the guide groove 601 between the display body 1 and the back cover 3, thereby achieving an all-round seal between the display body 1 and the back cover 3.

[0033] Among them, the card plate 6 and the guide groove 601 are both set in an arc shape away from the side of the sealing frame 2. The card plate 6 is made of elastic material such as rubber, so that when the card plate 6 is pushed into the guide groove 601, the card plate 6 will be bent into an arc shape. The card plate 6 passes through the guide groove 601, so that the card plates 6 on both sides of the sealing frame 2 pass through the guide groove 601 and will respectively rest against the sides of the light guide plate 4 and the positioning plate 402, so that the card plate 6 can support the light guide plate 4 and the positioning plate 402.

[0034] As attached Figure 1 To Attachment Figure 5 As shown: a support groove 701 is provided on one side of the light guide plate 4 and the positioning plate 402 near the guide groove 601, and a top block 7 is fixedly connected to the card plate 6 near the support groove 701, so that when the card plate 6 passes through the guide groove 601, the card plate 6 will push the top block 7 into the support groove 701 to limit the position, and then when the installation gap between the display body 1 and the back cover 3 is aged and the gap between them is enlarged, the card plate 6 will stretch in the guide groove 601, so that the card plate 6 will be straightened to support the top block 7 in the support groove 701, so that the guide plate 4 will not be offset due to the external structure, and the positioning effect is better.

[0035] Among them, a bevel 602 is opened on the side wall of the card plate 6, and a plurality of bevels 602 are arranged in sequence, so that the card plate 6 is not prone to breakage and other problems during the deformation process of the card plate 6, thereby improving the service life.

[0036] Working principle: The connection between the display body 1 and the back cover 3 is embedded in the limiting grooves 201 on both sides of the sealing frame 2, so that when the back plate 401 is installed in the installation cavity 301 between the display body 1 and the back cover 3, the light guide plate 4 and the positioning plate 402 on both sides of the back plate 401 are respectively inserted into the positioning grooves 5 in the display body 1 and the back cover 3 for limiting. When the light guide plate 4 is installed in the positioning plate 5, the light guide plate 4 will be positioned and guided by the positioning silica gel 501 in the positioning groove 5, so that the light guide plate 4 can be installed more accurately, so that the back cover 3 can be installed in the back cover 3. When the display body 1 is positioned on the back, the card plate 6 on the side wall of the sealing frame 2 will be pushed into the guide groove 601, and the side end of the card plate 6 will pass through the guide groove 601 to push the top block 7 into the side support groove 701 of the light guide plate 4 and the positioning plate 402 for positioning. When the installation gap between the display body 1 and the back cover 3 ages and causes the gap to expand, the card plate 6 will stretch in the guide groove 601, so that the card plate 6 will stretch through the bevel 602 to support the top block 7 in the support groove 701, thereby preventing the guide plate 4 from being offset due to the external structure, and achieving a better positioning effect.
