The weak adhesive layer 30 is located at the opening end of the accommodating groove 12, so that the stabilizing stress of the middle frame 10 on the adhesive tape 40 at the opening of the accommodating groove 12 is reduced, so that the adhesive tape 40 is easily separated from the middle frame 10 at the opening of the accommodating groove 12 of the middle frame 10, that is, under the driving of the adhesive tape 40, the functional device 20 is easily separated from the middle frame 10 at the opening of the accommodating groove 12 of the middle frame 10, thereby facilitating the detachment of the functional device 20 from the middle frame 10 and preventing the adhesive tape 40 from being damaged.

The bonding area 11 is located at the bearing surface 151, that is, the weak adhesive layer 30 is located at the bearing surface 151 and is adjacent to the adhesive tape 40 where the base 15 is bonded. The weak adhesive layer 30 reduces the bonding stress of the tape 40 to the base plate 15 at the bearing surface 151 so that the tape 40 is easily detached from the base plate 15. After the end of the tape 40 attached to the weak adhesive layer 30 is separated from the base plate 15, the functional device 20 is easily separated from the receiving groove 12.
In another embodiment, referring to fig. 19, the bearing surface 151 is provided with a third groove 152. The weak adhesive layer 30 is attached to the third groove 152. The weak adhesive layer 30 is attached to the bottom of the third groove 152. The third groove 152 is opened in a direction parallel to the opening of the receiving groove 12. The end of the tape 40 remote from the functional device 20 is received in the third recess 152. Avoiding an increase in the overall height of the tape 40 and the base plate 15. The opposite side of the tape 40 from the weak adhesive layer 30 is flush with the bearing surface. The third groove 152 protects the end of the adhesive tape 40 away from the functional device 20, and prevents the end of the adhesive tape 40 away from the functional device 20 from being warped or rolled. The third groove 152 may also identify the end of the tape 40 remote from the functional device 20, facilitating tearing of the end of the tape 40 remote from the functional device 20 by a user.
Further, referring to fig. 20, the housing 100 further includes a front cover 101 and a back cover 102 that is closed with respect to the front cover 101. The front cover 101 is composed of a glass layer and a display screen. The back cover 102 is a metal battery cover. The middle frame 10 is fixed between the front cover 101 and the back cover 102.
The present invention further provides a housing assembly 200, referring to fig. 21 and 22, the housing assembly 200 includes the housing 100 described above, and the housing assembly 200 further includes an adhesive tape 40, where the adhesive tape 40 has an adhesive end 41 and a Yi Laduan 42 disposed opposite the adhesive end 41. The adhesive end 41 is used for adhering the functional device 20, and the easy-open end 42 is fixed on the middle frame 10 at a position far away from the functional device 20. The weak adhesive layer 30 is adhered to the Yi Laduan or between the Yi Laduan and the adhesive end 31.
In this embodiment, the adhesive tape 40 is composed of a base layer and an adhesive material provided on the base layer. The adhesive material on the adhesive end 41 has a viscosity greater than that of the adhesive material on the Yi Laduan, i.e., the adhesive force of the adhesive end 41 to the middle frame 10 is greater than that of the Yi Laduan 42 to the functional device 10. When the Yi Laduan is subjected to a tensile force, the tensile force is larger than the bonding force of the Yi Laduan 42 to the middle frame 10 and smaller than the bonding force of the bonding end 41 to the functional device 20, so that the Yi Laduan is separated from the middle frame 10, and the bonding end 41 is fixed to the functional device 20. The weak adhesive layer 30 does not adhere to the adhesive tape 40, so that the middle frame 10 has less stress on the adhesive tape 40, and the adhesive tape 40 is not easily broken. In one embodiment, the Yi Laduan is received within the first groove 133. The effective length of the tape 40 is reduced, reducing the cost of the tape 40. The overall height of the adhesive tape 40 and the support plate 13 is reduced, improving the user experience.
In another embodiment, referring to fig. 23, the Yi Laduan is attached to the outer side of the open end of the first groove 133. The weak adhesive layer 30 is adhered between the Yi Laduan and the adhesive end 41. The effective length of Yi Laduan increases, resulting in an increase in the internal stress of Yi Laduan 42, and an increase in the internal stress of Yi Laduan 42 to adhesive end 41, resulting in less breakage of adhesive tape 40.
Further, the adhesive end 41 has a first connection face 411. The first connecting surface 41 is attached to a surface of the functional device 20 facing the middle frame 10. So that the bonding end 41 is clamped between the functional device 20 and the middle frame 10, and after the Yi Laduan is separated from the middle frame 10, the Yi Laduan applies a pulling force to the bonding end 41, so that the bonding end 41 pulls the functional device 20 to separate from the middle frame 10, thereby detaching the functional device 20 from the middle frame 10.
Further, referring to fig. 24, the adhesive end 41 further has a second connecting surface 412 opposite to the first connecting surface 411, and the second connecting surface 412 abuts against the middle frame 10. The second connecting surface 412 abuts against the bottom plate 15 of the middle frame 10. The base plate 15 applies an abutting force to the bonding end 41 so that the bonding end 41 firmly bonds the functional device 20. The adhesive end 41 is not easily separated from the functional device 20, and when the Yi Laduan 42 pulls the adhesive end 41, the adhesive end 41 effectively transmits the pulling force to the functional device 20.
Further, the bonding end 41 bonds the bottom plate 15 of the middle frame 10 at the second connecting surface 412. The adhesive end 41 is provided with an adhesive coating on the second connection surface 412, and the adhesive end 41 adheres to the bottom plate 15 at the connection surface 412.

The main board 50 is provided with a notch 51 near the edge of the accommodating groove 12. The notch 51 faces the first groove 133. The Yi Laduan 42 is pulled out through the notch 51, thereby separating the Yi Laduan 42 from the middle frame 10. The Yi Laduan applies a pulling force to the adhesive end 41, and the adhesive end 41 drives the functional device 20 to separate the middle frame 10, so that the functional device 20 is detached from the middle frame 10.
In another embodiment, referring to fig. 26, the weak adhesive layer 30 is attached to the main board 50.

After the adhesive tape 40 is separated from the supporting surface 52 and the side surface 53 of the main board 50, the adhesive tape 40 may apply a force to the functional device 20 along the opening direction of the accommodating groove 12, so that the adhesive tape 40 is convenient to drive the functional device 20 to be separated from the accommodating groove 12.
