Description

Technical Field

[0001] This utility model relates to a video intercom terminal with an external screen protection structure. Background Technology

[0002] Currently, video intercom terminals, as important equipment for intelligent security and building communication, are widely used in residential communities, office buildings, and other places. Traditional video intercom terminals usually consist of an indoor unit and an outdoor unit. The outdoor unit needs to be exposed to the outdoor environment for a long time, making it susceptible to corrosion from natural factors such as rain, dust, and ultraviolet rays. It may also be subject to the risk of human impact or vandalism.

[0003] In existing technologies, although some outdoor units are equipped with simple protective structures, their outer screens (such as display screens or camera protective lenses) are mostly made of ordinary glass or plastic, which have weak impact resistance. After long-term use, they are prone to scratches, cracks, or blurring, affecting the display effect and user experience. In addition, some products use metal fences or outer frames for physical protection, but such designs often obstruct the screen view, hinder camera shooting, and are bulky and lack aesthetics.

[0004] Therefore, there is an urgent need for a new type of protective structure for the outer screen of a video intercom terminal, which can effectively improve the impact resistance, scratch resistance and environmental resistance of the outer screen while taking into account both aesthetics and functionality, and extend the service life of the equipment. Utility Model Content

[0005] This invention provides a video intercom terminal with an external screen protection structure, which can effectively solve the above problems.

[0006] This utility model is implemented as follows:

[0007] A video intercom terminal with an external screen protection structure, including

[0008] The device body has a display screen on its front side;

[0009] A multi-functional protective structure is fitted onto the outside of the device body for impact protection and portable installation; the multi-functional protective structure includes a first protective sleeve and a second protective sleeve, and a support pad disposed between the first protective sleeve and the second protective sleeve.

[0010] The front end faces of the first and second protective sleeves are provided with flexible edging. The flexible edging extends inward and surrounds the edge of the display screen, and is made of elastic material. When the device body is subjected to an impact perpendicular to the display screen, the flexible edging can bend and deform in the direction of the display screen until it fits the surface of the display screen to disperse the impact force.

[0011] A first nest and a second nest are provided at one end of the first protective sleeve and the second protective sleeve;

[0012] The first and second protective sleeves have rounded transition structures at both ends, and a lifting structure is provided on the rear end face.

[0013] The beneficial effects of this utility model are:

[0014] (1) This utility model achieves dual protection through a multi-functional protective structure sleeved on the outside of the device body. The first protective sleeve and the second protective sleeve are connected by the first nesting and the second nesting to form the main frame, and the support pad between the two provides buffer support. When the terminal is subjected to vertical impact, the flexible edge made of elastic material at the front end will immediately bend and deform towards the display screen and completely fit the surface of the display screen, effectively dispersing and absorbing the impact energy and preventing screen damage. At the same time, the arc transition structure at both ends of the protective sleeve further alleviates the side impact force, while the rear lifting structure facilitates the handling and installation of the equipment. The whole protective system achieves all-round impact protection while ensuring the normal use function of the equipment, significantly improving the durability and service life of the product.

Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0024] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] Reference Figure 1-4 As shown, a video intercom terminal with an external screen protection structure includes a device body 10, and a display screen is provided on the front of the device body 10.

[0026] A multi-functional protective structure 20 is fitted onto the outside of the device body 10 for impact protection and portable installation. The multi-functional protective structure 20 includes a first protective sleeve 200 and a second protective sleeve 202, and a support pad 206 disposed between the first protective sleeve 200 and the second protective sleeve 202. A rear panel 204 is provided at the corner of the rear end face of the first protective sleeve 200 and the second protective sleeve 202. A first nest 210 and a second nest 212 are provided at one end of the first protective sleeve 200 and the second protective sleeve 202. An installation port 214 is provided on one side of the second protective sleeve 202 (for matching the button on the side of the device body 10, and the edge of the installation port 214 is provided with an annular silicone sealing ring).

[0027] Furthermore, the first protective sleeve 200 and the second protective sleeve 202 adopt a three-layer composite structure: outer layer: polycarbonate hard shell (thickness 1.2-1.5mm); middle layer: foamed polyurethane buffer layer (density 0.3-0.5g / cm3); inner layer: microfiber cloth (weight 150-200g / m2), thereby enhancing the protective performance of the device.

[0028] The support pad 206 has a strip groove 2060 inside. A tension spring 2062 (with an elastic coefficient of 5-8 N / mm and a maximum tensile stroke of 15-20 mm) is installed inside the strip groove 2060. One end of the tension spring 2062 pulls the second protective sleeve 202, thereby increasing the distance between the first protective sleeve 200 and the second protective sleeve 202.

[0029] Specifically, the width of the first protective sleeve 200 and the second protective sleeve 202 is greater than the width of the device body 10, and the excess portion forms a buffer gap of 5-10mm.

[0030] The front ends of the first protective sleeve 200 and the second protective sleeve 202 are provided with flexible edging 208. The flexible edging 208 extends inward and surrounds the edge of the display screen, and is made of an elastic material. When the device body 10 is subjected to an impact perpendicular to the display screen, the flexible edging 208 can bend and deform towards the display screen until it conforms to the surface of the display screen to disperse the impact force. In one embodiment, to verify the performance of the flexible edging 208, further experimental verification was conducted, as follows.

[0031] A silicone edge sample with a Shore hardness of 70A (2mm thickness, 45° elongation angle) was tested using a universal testing machine.

[0032] Under 1J impact energy, the edge bends 90° and fits the display screen within 8ms, with the impact force attenuated by 65%.

[0033] After 10,000 bending cycles, no visible cracks appeared, and the permanent deformation rate was 3.2%. Compared with ordinary PVC edging (of the same thickness), this solution improves the impact force attenuation rate by 40% and increases fatigue life by 5 times.

[0034] Specifically, the extension direction of the flexible edging 208 forms an angle of 30°-60° with the surface of the display screen. Preferably, in order to most effectively decompose the impact force into parallel and perpendicular components (each accounting for approximately 70.7%) when subjected to vertical impact, ensuring both sufficient bending deformation space and ensuring the response speed of the display screen, the angle is approximately 45°. Furthermore, compared to 30° (too gentle) which would occupy more lateral space, or 60° (too vertical) which might affect the bending range, 45° achieves the best balance between protection range and structural compactness. At the same time, at this angle, the tensile and compressive stress distribution of the elastic material (such as silicone) is most uniform, avoiding fatigue fracture caused by local stress concentration.

[0035] The first protective sleeve 200 and the second protective sleeve 202 have rounded transition structures at both ends, and a lifting structure is provided on the rear end face; the lifting structure includes rubber sleeves 216 symmetrically arranged on the first protective sleeve 200 and the second protective sleeve 202, and a lifting member sleeved between the rubber sleeves 216; the lifting member includes a fixing strap 2160 (the fixing strap 2160 is made of 1680D nylon braided tape, with a width of 25-30mm and a breaking strength ≥2000N), a telescopic strap 2162 woven with the fixing strap 2160, and a telescopic strap 2162 The mounting plate 2164 is made of textile fabric; the surface of the fixing band 2160 has a plurality of fastening holes 21600; a connecting end 21602 is provided at one end of the fixing band 2160; a metal ring 21604 (the metal ring 21604 is made of 304 stainless steel, with an inner diameter of 8-10mm and a wall thickness of 1-1.2mm) is fitted onto the connecting end 21602; the mounting plate 2164 is provided with a buckle 21640 (the buckle 21640 is made of POM plastic, with a buckling force of 15-20N) for fastening with the fastening holes 21600.

[0036] Working principle:

[0037] Dual protection is achieved through a multi-functional protective structure fitted onto the outside of the device body. The first protective sleeve 200 and the second protective sleeve 202 are connected to the receiving rod on the device through the first nest 210 and the second nest 212 to form the main frame. The support pad 206 between the two has a built-in tension spring 2062 to adjust the spacing between the protective sleeves. When the terminal is impacted, the front flexible edge 208 (a 30°-60° inclined elastic material structure) will bend and deform to fit the display screen and disperse the impact force. At the same time, the 5-10mm buffer gap formed by the width of the protective sleeve exceeding the body and the rounded transition structure at both ends work together to absorb the impact. The lifting structure at the rear end enables portability through an adjustable textile belt assembly, while the mounting port 214 on the side ensures the normal operation of the buttons on the body. The entire protective system provides all-round impact protection while maintaining the functional integrity of the device.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
