When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

With the rapid development of screen technology, the wide application of flexible screens makes the display area of the mobile terminal have a larger design space. However, the structure located on another plane becomes an obstacle to display of a design space, and the position of the card mounting assembly greatly affects the form of the mobile terminal and the design space of the mobile terminal as an indispensable structure of the mobile terminal.

As shown in fig. 1-3, an embodiment of the present disclosure proposes a mobile terminal 1, the mobile terminal 1 including a housing 2 and a card mounting assembly. The housing 2 has a front face and a rear face 21. The card mounting assembly is provided on the back 21 of the housing 2. The card mounting assembly includes a card holder 105 for mounting a card 103 and a cover 101 for covering the card holder 105.

The cover plate 101 and the substrate 201 are installed in a matched manner, so that the longitudinal depth of the installation groove 111 can be reduced, the occupation of the stacking space inside the mobile terminal is reduced, and the yielding degree of the shell 2 can be reduced. Since the base plate 201 protrudes from the rear surface 21 of the housing 2, a stopper is formed for the cover plate 101. The substrate 201 and the shell 2 can be arranged in a split mode, and the processing difficulty of the shell is reduced. It can be understood that the housing 2 may be provided with a second through hole, and the substrate 111 may also be directly connected to the middle frame of the mobile terminal through the second through hole, or fixedly connected to the middle frame through a positioning structure on the housing, so as to improve the connection effect and the overall appearance effect of the substrate and the mobile terminal.

In some embodiments, in order to improve the overall feeling and flatness of the mobile terminal, when the base plate 201 and the cover 101 are in a fitted state, and the back surface of the cover 101 is flush with the back surface (outer surface) of the base plate 201, the cover 101 is in a closed state, and the outer surface of the cover 101 is flush with the outer surface of the base plate 201. .

In some embodiments, the cover 101 is connected to the base plate 201 and can be turned between an open position for opening the mounting groove 111 and a closed position for closing the mounting groove, and the cover 101 may be provided with a pivot portion connected to the base plate 201 via a pivot shaft and still connected to the housing when the cover 101 is opened, thereby preventing the cover 101 from being lost.

In some embodiments, the lid 101 is removable by, in addition to adhesive, interference fit, etc., a first push-to-eject mechanism for locking the lid 101 in a closed position and for ejecting the lid 101 into an open position by pushing. The biasing mechanism can be powered by a torsion spring and is disposed at the matching position of the base plate 201 or the mounting groove 111 and the cover 101, when the cover 101 is closed, the cover 101 presses the biasing mechanism, the torsion spring compresses, and the biasing mechanism locks the cover 101 through the engaging part. When it is necessary to open the cover, the pressing lid 101 is pressed again to apply additional pressure, so that the engaging portion of the biasing mechanism is released and the cover is biased by the torsion spring force.

In some embodiments, the cartridge 105 is pivotally mounted in the mounting slot 111 between a first position in which the cartridge 105 is received in the mounting slot 111 and a second position in which a portion of the cartridge 105 extends out of the mounting slot 111 to facilitate removal of the card 103. As shown in fig. 1, the card seat can be divided into a seat body and a card pressing member, the seat body and the card pressing member are connected through a pivot, the seat body is arranged in the installation groove 111, the card seat 105 is in an open state, part of the card pressing member extends out of the installation groove 111, installation space is provided for the card 103, when the card pressing member is in a closed state, the card 103 is limited in a gap between the seat body and the card pressing member, the card pressing member abuts against the back of the card 103, when the card pressing member is in a closed state, the card pressing member and the seat body can be matched and connected in corresponding areas on different sides of the pivot, such as a buckle and a magnetic suction, so as to achieve a locking effect, and the card 103 is more firmly fixed in the installation groove 111.

In some embodiments, it is understood that the mounting groove 111 may further include a second push-out mechanism for locking the holder body and the clamper at the closed position and pushing out the clamper to the open position by pushing. The elastic pressing mechanism can provide power through a torsion spring and is arranged at the matching position of the base and the pressing clamping piece, when the pressing clamping piece closes, the pressing clamping piece presses the elastic pressing mechanism, the torsion spring compresses, and the elastic pressing mechanism locks the pressing clamping piece through the base. When needing to open, press again and press the fastener and provide additional pressure, make the block portion of suppressing mechanism loosen, bounce off under the effect of torsional spring power.

In some embodiments, the mobile terminal further comprises a lifting device (not shown in the figures), which can be driven by a motor, for lifting or retracting the card holder 105 and the cover 101. Taking the card seat 105 as an example, the lifting device can be released by pushing the switch through a thimble, or by a push-push structure; or may be triggered by software. When the motor receives the corresponding indication signal, the motor is started to eject the whole card seat 105 out of the mounting groove 111, the ejection mode can be realized by connecting a screw rod with the motor, the screw rod can be movably connected with the middle frame, and the screw rod rotates to generate relative displacement with the mobile terminal body.
