Referring to fig. 5, in an embodiment, the second rear case 130 has a through hole 140 formed therein, and the fingerprint module 400 is exposed from the through hole 140. Specifically, in an embodiment, the through hole 140 is located on a side of the second rear case 130 facing away from the display screen 200, the through hole 140 penetrates through an edge of the second rear case 130, and the fingerprint module 400 is exposed from the inside and the outside of the through hole 140 in the first position. In one embodiment, the outer surface of the second rear case 130 at the outer circumference of the through hole 140 is gradually sunk from a position far from the inner edge of the through hole 140 to a position where the through hole 140 is located, and the edge of the through hole 140 is chamfered to prevent the edge of the through hole 140 from having a sharp portion. The structure is beneficial to positioning the fingertip of the user to the through hole 140 on the second rear shell 130 on one hand, so as to facilitate the user to perform the operation of fingerprint identification; on the other hand, the through hole 140 and the fingerprint module 400 installed therein can be used as a stress point of the second rear housing 130, so that the user can apply a pushing force to the second rear housing 130, and further the second rear housing 130 can be pushed to slide on the bearing portion 120, so that the first rear housing 110 and the second rear housing 130 can be separated.

According to the mobile terminal 10, the functional device 300 is shielded by the display screen 200 when in the first position, and is exposed from the side where the display screen 200 is located when in the second position, and the functional device 300 can be hidden and exposed by sliding the second rear shell 130 on the bearing part 120, so that the functional device 300 is prevented from occupying the area of the side where the display screen 200 of the mobile terminal 10 is located, and the screen occupation ratio of the mobile terminal 10 is further improved. For example, the screen occupation ratio of the mobile terminal 10 having the above-described configuration may be 85% or more, so that a high screen occupation ratio of the mobile terminal 10 may be achieved. Because the fingerprint module 400 is disposed on the carrying portion 120, the position of the fingerprint module 400 is fixed relative to the position of the first rear case 110.

It is understood that the difference in level can be regarded as a height difference between the bottom wall 111 and the outer surface of the bearing part 120, and the fracture surface 112 is generated at the connecting position of the bottom wall 111 and the bearing part 120. In the first position, the section 112 abuts the second rear shell 130. In the second position, the section 112 is separated from the second rear housing 130. Further, referring to fig. 3, in an embodiment, an intersection line of the section 112 and the outer surface of the bottom wall 111 is a straight line, and an included angle between the intersection line of the section 112 and the outer surface of the bottom wall 111 and the length direction of the mobile terminal 10 is a right angle or an acute angle.

In one embodiment, the intersection of the cross-section 112 and the outer surface of the bottom wall 111 includes an angle in the range of 45 degrees to 85 degrees with respect to the y-axis. The above arrangement makes the length of the intersection line of the cross section 112 and the outer surface of the bottom wall 111 greater than the width of the mobile terminal 10, thereby being beneficial to extending the contact length between the second rear housing 130 and the first rear housing 110, and further enabling the second rear housing 130 and the first rear housing 110 to be more stably buckled when in the first position.

In one embodiment, the outer surface of the bottom wall 111 smoothly transitions with the outer surface of the first side peripheral wall 113 and the outer surface of the second side peripheral wall 115, respectively. Specifically, the connection portion between the outer surface of the bottom wall 111 and the outer surface of the first side peripheral wall 113 may adopt a curved surface, such as a cambered surface transition, so that the outer surface of the bottom wall 111 and the outer surface of the first side peripheral wall 113 are smoothly transitioned. The connection portion between the outer surface of the bottom wall 111 and the outer surface of the second side peripheral wall 115 may adopt a curved surface, such as a cambered transition, so as to smoothly transition the outer surface of the bottom wall 111 and the outer surface of the second side peripheral wall 115. With the above structure, the appearance of the mobile terminal 10 can be made more beautiful.

Further, referring to fig. 4, in an embodiment, the first rear shell 110 may further include a third side peripheral wall 117 and a fourth side peripheral wall 119, the third side peripheral wall 117 is connected to one end of the first side peripheral wall 113 and the second side peripheral wall 115, and the fourth side peripheral wall 119 is connected to the other end of the first side peripheral wall 113 and the second side peripheral wall 115.

The outer surface of the first peripheral wall 133 is flush with the outer surface of the first side peripheral wall 113, and the outer surface of the second peripheral wall 135 is flush with the outer surface of the second side peripheral wall 115. When the second rear case 130 is located at the first position, the above structure makes the outer appearance of the side where the outer surface of the bottom wall 111 of the mobile terminal 10 is located flat. The other end of the base plate 131 abuts the cross-section 112 in the first position and is separated from the cross-section 112 in the second position. The above arrangement is advantageous in maintaining the appearance integrity of the mobile terminal 10, for example, the appearance integrity of the mobile terminal 10 is high when the second rear case 130 is in the first position.

In one embodiment, the outer surface of the bottom panel 131 smoothly transitions with the outer surface of the first peripheral wall 133, the outer surface of the second peripheral wall 135, and the outer surface of the end wall 137, respectively. Specifically, the connection portion between the outer surface of the bottom plate 131 and the outer surface of the first peripheral wall 133 may adopt a curved surface, such as an arc transition, so that the outer surface of the bottom plate 131 and the outer surface of the first peripheral wall 133 are smoothly transitioned. In an embodiment, a connecting portion between the outer surface of the bottom plate 131 and the outer surface of the second peripheral wall 135 may adopt a curved surface, such as a cambered transition, so that the outer surface of the bottom plate 131 and the outer surface of the second peripheral wall 135 smoothly transition.

It will be appreciated that the outer surface of the bottom plate 131 and the outer surface of the end wall 137 may also be smoothly curved.

Referring to fig. 5, in an embodiment, the through hole 140 penetrates through an edge of the bottom plate 131, and the through hole 140 has a structure with one end open in a length direction of the mobile terminal 10. The above structure can prevent the fingerprint module 400 from interfering the sliding of the second rear housing 130 on the carrying portion 120, and is favorable for processing the through hole 140.

Referring to fig. 6 and 7, in another embodiment, the bottom plate 131 has an end surface 138 facing away from the end wall 137, and the through hole 140 is located between the end wall 137 and the end surface 138 of the bottom plate 131, and the through hole 140 has a structure closed at both ends in the length direction of the mobile terminal 10.

The maximum length of the through hole 140 may be greater than or equal to the maximum moving distance of the second rear case 130 between the first position and the second position. For example, in one embodiment, the maximum length of the through hole 140 is equal to the maximum moving distance of the second rear case 130 between the first position and the second position. When the second rear housing 130 moves to the first position, the fingerprint module 400 abuts against the hole wall at one end of the through hole 140; when the second rear housing 130 moves to the second position, the fingerprint module 400 abuts against the hole wall at the other end of the through hole 140. The hole wall of the through hole 140 may be used for limiting the second rear case 130 to define the moving range of the second rear case 130. In other embodiments, an avoiding groove may be formed on an inner surface of the bottom plate 131 of the second rear case 130, and the avoiding groove is in communication with the through hole 140. When the second rear case 130 slides, the portion of the fingerprint module 400 protruding from the carrying portion 120 can be accommodated in the avoiding groove. The structure of the avoiding groove facilitates to reduce the thickness of the second rear case 130, thereby facilitating to thin the mobile terminal 10.

Specifically, in an embodiment, a surface of the carrying portion 120 facing away from the display screen 200 is planar, the fingerprint module 400 protrudes from the carrying portion 120, and a portion of the fingerprint module 400 protruding from the carrying portion 120 can be received in the through hole 140 of the second rear housing 130. In an embodiment, a side of the second rear shell 130 facing the bearing part 120 is a plane, and the second rear shell 130 can be attached to the bearing part 120 and can slide along the bearing part 120. When the thickness of the substrate 121 is smaller than that of the bottom wall 111, the processing of the carrier 120 is facilitated. For example, the bearing part 120 may be integrally formed with the bottom wall 111, and the bearing part 120 may be obtained by removing material.

Referring to fig. 9 and 10, in an embodiment, the supporting portion 120 may further include a first side plate 123 and a second side plate (not shown) extending from two opposite edges of the base plate 121, the first side plate 123 is connected to the first side wall 113, and a thickness of the first side plate 123 is smaller than a thickness of the first side wall 113, and the second side plate is connected to the second side wall 115, and a thickness of the second side plate is smaller than a thickness of the second side wall 115. The second rear housing 130 defines a receiving cavity 170, and the bottom plate 131, the first peripheral wall 133, the second peripheral wall 135 and the end wall 137 define the receiving cavity 170.

The above structure facilitates the assembly of the second rear case 130 with the first rear case 110, and facilitates the sliding of the second rear case 130 on the bearing part 120. For example, the first and second

peripheral walls

133, 135 of the second rear shell 130 can be used to play a guiding role to facilitate the sliding of the second rear shell 130 on the bearing part 120.

One end of the thimble 720 abuts against the elastic element 710, and the other end of the thimble 720 is exposed out of the mounting groove 800 and protrudes out of the edge of the first side plate 123. When the second rear case 130 slides along the length direction of the mobile terminal 10, the thimble 720 may compress the spring, so that the spring generates an elastic force, thereby causing the thimble 720 to slide and extend in the width direction of the mobile terminal 10. The protruding portion of thimble 720 can slide into morton groove 180 or slide out of morton groove 180, thereby generating a distinct pause feeling.

Further, in one embodiment, thimble 720 includes a body portion 721 and a boss 723, and body portion 721 is integrally formed with boss 723. The main body portion 721 has a substantially cylindrical shape, one end of the main body portion 721 is connected to the boss 723, and the other end of the main body portion 721 abuts against the second rear case 130. The boss 723 is substantially cylindrical, one end of the boss 723 is connected to the main body portion 721, the other end of the boss 723 abuts against the elastic member 710, and the maximum width of the boss 723 is greater than the maximum width of the main body portion 721. In one embodiment, the mounting groove 800 includes a first groove 810 and a second groove 820, the first groove 810 and the second groove 820 are communicated, and the first groove 810 and the second groove 820 both extend in a width direction of the mobile terminal 10, and a maximum width of the first groove 810 is greater than a maximum width of the second groove 820.
