Description

Technical Field

[0001] This utility model relates to the field of intercom indoor unit technology, and specifically to a screen assembly structure and an intercom indoor unit. Background Technology

[0002] With the development of the intercom industry, the appearance design of equipment has become a key factor in enhancing product competitiveness. For indoor intercom units, besides the screen UI, the user's first visual touchpoint mainly focuses on the thickness of the bezel and the overall texture of the device. Therefore, the design of the screen assembly structure is crucial. It needs to achieve the narrowest bezel, thinnest profile, and best display effect while ensuring assembly reliability, and also taking production costs into account.

[0003] Currently, the mainstream solutions for screen assembly in the industry are mainly divided into the following two types: 1. Fitting Solution This solution includes frame bonding or full bonding, which is usually installed from the front of the product, by directly bonding the touch screen to the screen or front shell using adhesive backing or spot bonding.

[0004] 2. Backpacking solution The solution first fixes the touchscreen to the front shell using adhesive backing or spot adhesive, and then inserts the screen from the rear and locks it to the front shell with screws, so that the screen and the touchscreen are sandwiched between the front shell.

[0005] However, both types of assembly schemes have the following drawbacks: While the bonding solution has advantages such as high assembly efficiency, reliable connection, and good dustproof effect, its assembly cost is too high, which has a certain impact on the product's market competitiveness.

[0006] While back-mounted solutions are less expensive, they significantly increase the device's bezel width and overall thickness due to the need to accommodate the front shell's clamping structure, hindering slim and aesthetically pleasing designs. Furthermore, dust can easily accumulate at the interface between the screen and touchscreen during assembly, affecting usability. Utility Model Content

[0007] The purpose of this utility model is to provide a screen assembly structure and an intercom indoor unit, which reduces the overall thickness of the unit after screen installation and ensures the display effect of the screen.

[0008] To achieve the above objectives, the solution of this utility model is as follows: An intercom indoor unit screen assembly structure includes a front shell, a screen, and a touch screen. The front shell has a stepped surface, the screen abuts against the stepped surface around its perimeter and is fixedly connected to the front shell by clips, and the touch screen is fixedly installed on the front shell for user touch interaction and to cover the screen. The size of the touch screen's sensing area is smaller than the size of the screen, and there is a gap between the sensing area and the screen. The front shell has a stepped retaining wall at a position corresponding to the stepped surface to seal the gap.

[0009] In a preferred embodiment, the gap is 0.6~1.2mm.

[0010] In a preferred embodiment, the touchscreen is fixedly mounted on the front housing using adhesive backing or dispensing.

[0011] In a preferred embodiment, the buckle includes an elastic buckle and a fixed buckle, which are disposed on the inner side of the frame of the front shell, and the two sides of the screen are fixedly connected to the front shell by the elastic buckle and the fixed buckle, respectively.

[0012] In a preferred embodiment, the elastic buckle includes a support arm and a first locking block. The support arm is made of an elastic material and is disposed inside the frame of the front shell and perpendicular to the stepped surface. The first locking block is horizontally disposed on the support arm.

[0013] In a preferred embodiment, the fixing buckle includes a second locking block, which is horizontally disposed on the edge of the front shell.

[0014] In a preferred embodiment, a rear shell is also included, which is fixedly mounted on the front shell by clips or bolts.

[0015] In a preferred embodiment, the screen is an IPS screen.

[0016] An intercom indoor unit, employing the screen assembly structure of an intercom indoor unit as described above.

[0017] After adopting the above solution, the beneficial effects of this utility model are as follows: The touchscreen of this invention is fixedly mounted on the front shell, and the size of the touchscreen's sensing area is smaller than the screen size, allowing for a further reduction in the gap between the touchscreen and the screen, thus decreasing the overall thickness of the device after installation. Furthermore, the front shell has a stepped retaining wall at a position corresponding to the stepped surface, which seals the gap between the touchscreen's sensing area and the screen, preventing dust intrusion during installation and improving the screen's display quality and effect. Additionally, the screen rests against the stepped surface on all four sides and is fixedly connected to the front shell with clips; adjusting the area of ​​the stepped surface further reduces the front bezel of the device, enhancing its aesthetics.

[0020] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0021] This embodiment provides a screen assembly structure for an intercom indoor unit, such as... Figures 1 to 5 As shown, the device includes a front shell 1, a screen 2, and a touch screen 3. The front shell 1 has a stepped surface 11. The screen 2 rests against the stepped surface 11 around its perimeter and is fixedly connected to the front shell 1 by clips. The touch screen 3 is fixedly installed on the front shell 1, allowing users to interact with it and cover the screen 2. The size of the sensing area 31 of the touch screen 3 is smaller than the size of the screen 2, and there is a gap between the sensing area 31 and the screen 2. The front shell 1 has a stepped retaining wall 12 at a position corresponding to the stepped surface 11 to seal the gap.

[0022] In this embodiment, the screen 2 rests against the stepped surface 11 on all four sides and is fixedly connected to the front shell 1 by clips. The structure is simple, easy to install and remove, and ensures that the screen 2 is tightly fixed to the front shell 1. By adjusting the area of ​​the stepped surface 11, the front bezel of the entire device can be reduced, which helps to improve the overall aesthetics of the device.

[0023] In addition, there is a gap between the sensing area 31 of the touch screen 3 and the screen 2. The front shell 1 has a step retainer 12 at the position corresponding to the step surface 11 to seal the gap. The height of the step retainer 12 is greater than the height of the step surface 11, which can effectively prevent dust from entering, protect the screen 2 and the touch screen 3 from contamination and damage, improve the display quality and display effect of the screen 2, and extend the service life of the product.

[0024] Furthermore, since the size of the sensing area 31 of the touch screen 3 is smaller than that of the screen 2, the gap between the touch screen 3 and the screen 2 can be further reduced, thereby reducing the overall thickness of the device after the screen 2 is installed.

[0025] In existing technologies, such as Figure 6 As shown, a plastic spacer 7 is typically provided between the sensing areas 31 of the screen 2 and the touch screen 3. While the plastic spacer 7 assists in the installation of the screen 2, its presence also increases the distance between the sensing areas 31 of the screen 2 and the touch screen 3, thus affecting the overall thickness of the device.

[0026] In this embodiment, such as Figure 5 As shown, the gap is 0.6~1.2mm. In this embodiment, the gap between the sensing area 31 of the touch screen 3 and the screen 2 is set to 0.6mm, which not only reduces the overall thickness of the device after the screen 2 is installed, but also avoids water ripples on the screen 2 when the user touches it, thus improving the user experience.

[0027] like Figure 5 As shown, the touch screen 3 in this embodiment is fixedly installed on the front shell 1 by adhesive backing or dispensing, but is not limited to this method. This simplifies the installation process and improves the stability of the touch screen 3 after installation.

[0028] like Figure 1 and Figure 2 As shown, the buckle in this embodiment includes an elastic buckle 5 and a fixed buckle 6. The elastic buckle 5 and the fixed buckle 6 are disposed on the inner side of the frame of the front shell 1. The two sides of the screen 2 are fixedly connected to the front shell 1 by the elastic buckle 5 and the fixed buckle 6 respectively.

[0029] The elastic buckle 5 in this embodiment has a certain elastic deformation capability. When installing the screen 2, simply insert one side of the screen 2 into the fixing buckle 6 first, and then press the other side against the elastic buckle 5 and apply appropriate pressure. The elastic buckle 5 will then undergo elastic deformation, thereby fixing the screen 2 onto the front shell 1. The structure is simple and easy to install and remove.

[0030] like Figure 2 and Figure 3As shown, the elastic buckle 5 of this embodiment includes a support arm 51 and a first locking block 52. The support arm 51 is made of elastic material and is disposed inside the frame of the front shell 1 and perpendicular to the stepped surface 11. The first locking block 52 is horizontally disposed on the support arm 51.

[0031] In this embodiment, the support arm 51, which is perpendicular to the step surface 11, works in conjunction with the horizontal first locking block 52 to clamp and fix the screen 2 from both vertical and horizontal directions. The elasticity of the support arm 51 ensures a tight fit between the first locking block 52 and the screen 2, effectively preventing the screen 2 from becoming loose, shaking, or falling off during use. The structure is simple and easy to set up.

[0032] like Figure 2 and Figure 4 As shown, the fixing buckle 6 in this embodiment includes a second clip 61, which is horizontally arranged on the edge of the front shell 1. It can clamp and fix the screen 2 in conjunction with the edge of the front shell 1. The structure is simple and easy to set up.

[0033] like Figure 1 and Figure 5 As shown, this embodiment also includes a rear shell 4, which is fixedly installed on the front shell 1 by a snap fastener or bolts. The structure is simple and easy to install and remove. The snap fastener can also be the aforementioned elastic snap fastener 5 and fixed snap fastener 6. If bolts are used, a through hole needs to be opened on the rear shell 4 and a threaded seat needs to be provided at the corresponding position on the front shell 1. This is something that can be achieved by those skilled in the art, and will not be described in detail here.

[0034] Furthermore, in this embodiment, screen 2 is an IPS screen 2. By using elastic clips 5 and fixing clips 6 to fix screen 2, excessive pressure on screen 2 can be avoided, preventing problems such as yellowing of screen 2, improving the display quality and display effect of screen 2, and also extending its service life.

[0035] This embodiment also provides an intercom indoor unit. By applying the screen assembly structure of the above-mentioned intercom indoor unit, the overall thickness of the unit after screen installation can be reduced, dust can be prevented from entering during the installation process, the display quality and display effect of the screen can be improved, and the front bezel of the unit can be reduced, which is conducive to improving the aesthetics of the unit.

[0036] The directional terms used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0037] The above description is only a preferred embodiment of this utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
