Structural component and mobile terminal
A structural component includes a middle frame, a glass cover, and a touch control film. The glass cover and the touch control film are disposed in a stacked manner. The touch control film is disposed on a surface that is of the glass cover and that faces the middle frame, and a side edge of the touch control film and a side edge of the glass cover do not overlap completely. The glass cover is bonded using the first bonding adhesive, and the touch control film is bonded using the second bonding adhesive. The first bonding adhesive is bonded to an edge of the glass cover, and the bonding force of the first bonding adhesive is greater than the bonding force of the second bonding adhesive.
1. A structural component, comprising:
a middle frame;
a glass cover comprising a glass cover surface that faces the middle frame, a glass cover side edge, and an exposed area that comprises a first bonding area, wherein the first bonding area is adhesively connected to the middle frame using a first bonding adhesive;
a touch control film comprising a touch control film surface that faces the middle frame and a touch control film side edge;
a protrusion structure disposed on the middle frame and adhesively connected to the first bonding area using the first bonding adhesive; and
an adhesive overflow groove disposed on the protrusion structure,
wherein the glass cover and the touch control film are disposed in a stacked manner,
wherein the touch control film is disposed on the glass cover surface,
wherein the touch control film side edge and the glass cover side edge do not overlap completely,
wherein the glass cover surface is exposed to the touch control film,
wherein the touch control film surface comprises a second bonding area,
wherein the second bonding area is adhesively connected to the middle frame using a second bonding adhesive, and
wherein a first bonding force of the first bonding adhesive is greater than a second bonding force of the second bonding adhesive.
2. The structural component of claim 1 , wherein the first bonding area is disposed around the touch control film.
3. The structural component of claim 1 , wherein the first bonding adhesive is dispensed on the middle frame.
4. The structural component of claim 3 , wherein the protrusion structure and the middle frame are integrated.
5. The structural component of claim 1 , wherein the second bonding adhesive is a foam adhesive.
6. The structural component of claim 1 , further comprising a supporting protrusion that is disposed on the middle frame and that is configured to support the glass cover.
7. The structural component of claim 6 , further comprising a protrusion structure disposed on the middle frame, wherein the supporting protrusion is disposed on the protrusion structure and is between the first bonding adhesive and the second bonding adhesive.
8. The structural component of claim 6 , wherein the supporting protrusion and the middle frame are integrated as a whole.
9. A terminal, comprising:
a structural component, comprising:
a middle frame;
a glass cover comprising a glass cover surface that faces the middle frame, a glass cover side edge, and an exposed area that comprises a first bonding area, wherein the first bonding area is adhesively connected to the middle frame using a first bonding adhesive;
a touch control film comprising a touch control film surface that faces the middle frame and a touch control film side edge;
a protrusion structure that is disposed on the middle frame and that is adhesively connected to the first bonding area using the first bonding adhesive; and
an adhesive overflow groove disposed on the protrusion structure,
wherein the glass cover and the touch control film are disposed in a stacked manner,
wherein the touch control film is disposed on the glass cover surface,
wherein the touch control film side edge and the glass cover side edge do not overlap completely,
wherein the glass cover surface is exposed to the touch control film,
wherein the touch control film surface comprises a second bonding area,
wherein the second bonding area is adhesively connected to the middle frame using a second bonding adhesive, and
wherein a first bonding force of the first bonding adhesive is greater than a second bonding force of the second bonding adhesive.
10. The terminal of claim 9 , wherein the first bonding area is disposed around the touch control film.
11. The terminal of claim 9 , wherein the first bonding adhesive is dispensed on the middle frame.
12. The terminal of claim 9 , wherein the protrusion structure and the middle frame are integrated as a whole.
13. The terminal of claim 9 , wherein the second bonding adhesive is foam adhesive.
14. The terminal of claim 9 , wherein the structural component further comprises a supporting protrusion that is disposed on the middle frame and that is configured to support the glass cover.
15. The terminal of claim 14 , wherein the structural component further comprises a protrusion structure disposed on the middle frame, and wherein the supporting protrusion is disposed on the protrusion structure and is between the first bonding adhesive and the second bonding adhesive.
16. The structural component of claim 14 , wherein the first bonding adhesive is not in contact with the touch control film.
