Problems solved by technology

[0003] The disadvantage of installing the screen in this way is that the screen is in direct contact with the outer frame, and the impact force on the outer frame will be directly transmitted to the screen, causing the screen to break
Especially when the outer frame is made of metal materials, the screen will not have any buffer protection under impact, and the screen is easily damaged during use

Embodiment 1

[0030] Such as figure 1 with figure 2 As shown, the mobile phone screen assembly includes an outer frame 1, a display screen 2 and a rubber ring 3; the outer frame 1 is a ring structure adapted to the outline of the display screen 2, and the top of the outer frame 1 is a fixed surface 101, and the rubber ring 3 is pasted On the fixed surface 101; the top of the rubber ring 3 is provided with a hot-melt adhesive receiving groove 301, and the hot-melt adhesive receiving groove 301 extends for a week along the top of the rubber ring 3; The extended arc portion 202, the bottom of the arc portion 202 is attached to the top of the rubber ring 3, the bottom of the arc portion 202 completely covers the hot melt adhesive holding groove 301 and closes the hot melt adhesive holding groove 301; the hot melt adhesive holding groove 301 is filled with hot melt adhesive 4; the bottom of the hot melt adhesive tank 301 is evenly provided with a plurality of vertical through holes 307 for the...

Embodiment 2

[0035] Such as figure 2 As stated above, on the basis of Embodiment 1, the bottom cross-section of the arc-shaped portion 202 is an arc surface A203; the top cross-section of the rubber ring 3 is an arc surface matched with the arc surface A203 B302.

[0036] The arc surface A203 and the arc surface B302 are provided to increase the contact area between the display screen 2 and the rubber ring 3, so that the display screen 2 is fixed more firmly.

Embodiment 3

[0038] Such as figure 2 As mentioned above, this embodiment is based on Embodiment 1, the top outer edge of the rubber ring 3 is rounded to form a rounded surface A303; a gap is formed between the rounded surface A303 and the bottom of the arc portion 202 A304.

[0039] When the rubber ring 3 is impacted and deformed, the gap A304 provides a space for the deformation of the outer edge of the rubber ring 3, preventing the rubber ring 3 from directly squeezing the display screen 2 when the rubber ring 3 is impacted and deformed, and preventing the display screen 2 from being damaged under pressure.

Abstract

The invention discloses a mobile phone screen assembly; the top of the outer frame is a fixed surface, and a rubber ring is pasted on the fixed surface; the top of the rubber ring is provided with a hot melt adhesive receiving groove, and the hot melt adhesive receiving groove extends for a circle along the top of the rubber ring ;The display screen includes a plane part and an arc part extending outward along the edge of the plane part. The bottom of the arc part is attached to the top of the rubber ring. Closed; the hot melt adhesive storage tank is filled with hot melt adhesive; the bottom of the hot melt adhesive storage tank is evenly opened with multiple vertical through holes for the hot melt adhesive to pass through under pressure, and the diameter of the vertical through holes is 1mm; the fixing surface An adhesive groove for accommodating hot melt adhesive from the vertical through hole communicated with the vertical through hole is opened on the top, and the rubber ring is pasted on the fixed surface through the hot melt adhesive in the adhesive groove. The invention prevents the impact force from being directly transmitted to the display screen to cause damage to the display screen, and improves the impact resistance of the display screen. The invention has high manufacturing efficiency.

Description

technical field [0001] The present invention relates to an image display device. Background technique [0002] In the manufacturing process of mobile terminals, especially mobile phones, the screen is directly assembled on the outer frame. The assembly process is to place hot melt adhesive on the upper surface of the outer frame at intervals, then press the screen on the outer frame, and bond the screen and the outer frame with hot melt adhesive. [0003] The disadvantage of installing the screen in this way is that the screen is in direct contact with the outer frame, and the impact force on the outer frame will be directly transmitted to the screen, causing the screen to break. Especially when the outer frame is made of metal materials, the screen will not have any buffer protection under impact, and the screen is easily damaged during use. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provi...
