FIG. 1 is a perspective view of a mobile phone. The receiving seat 10 of the user identification card of the present invention can be arranged on the top surface of the mobile phone or other suitable positions. 2 to 4D show the first embodiment of the present invention; FIG. 2 shows the situation in the mobile phone, and a slot 60 is formed on the mobile phone casing 40 to accommodate the accommodating seat 10 of the aforementioned user identification card, which is fixed at the bottom of the slot 60 A ejection device, which is a curved elastic piece (that is, reed, or spring, or any other elastic member) 50, the curved part of the curved elastic piece 50 is installed at the bottom of the slot 60, when the receiving seat 10 is inserted When the slot 60 is in contact with the receiving seat 10, the curved portion is in contact with the receiving seat 10, and a clip is set on the top of the slot 60, which is a sliding part 20 (engagement device), and the sliding part 20 passes through a biasing device, which It is a spring 30 connected to the casing 40 of the mobile phone. Fig. 3 shows the user identification card receiving seat of the present invention, the receiving seat 10 is a plate-shaped rectangle, and is composed of a top end surface, a bottom end surface, a first side surface and a second side surface, and on two opposite sides (that is, the above-mentioned top surface and bottom surface) are respectively provided with flange 102, gap 101, and flange 103, slope 104, the gap 101 is located at the intersection of the top surface and the first side, when the receiving seat 10 is inserted into the slot 60, the sliding member 20 is located at a top of the slot 60 corresponding to the notch 101; the slope 104 is located at the intersection of the bottom end surface and the first side, when the receiving seat 10 is inserted into the slot 60, The inclined surface 104 can push the sliding member 20 away, so that the receiving base 10 can be smoothly inserted into the slot 60 . Referring to FIG. 4A , it shows the situation of the receiving seat 10 in the mobile phone. At this time, the notch 101 of the receiving seat 10 is caught by the protruding part of the slider 20 , so the receiving seat 10 presses the curved elastic piece 50 at the bottom. Referring to Fig. 4B, if you want to take out the receiving seat 10, you only need to move the sliding part 20 to the right with your fingers, so that the receiving seat 10 is not restricted by the sliding part 20 (that is, when the clamping effect of the engaging device is smaller than the elastic force of the curved elastic piece ), as a result, the receiving seat 10 will be ejected under the action of the restoring force of the bent elastic piece 50 .

The situation inside the mobile phone after taking out the receiving seat 10 is as shown in FIG. 2 .

Put the user identification card on the receiving seat 10, the folded edges 102, 103 can prevent the card from falling off, then insert the receiving seat 10 back into the mobile phone, the inclined surface 104 of the receiving seat 10 can push the sliding part 20 away, and the receiving seat 10 When inserted to a fixed position, the sliding member 20 is locked in the notch 101 of the receiving seat 10 again. After the assembly is completed, it is shown in Figure 4C (viewed from the side where the user identification card is placed on the receiving seat), where the reference numeral 10 represents the user identification card. FIG. 4D is a side view of FIG. 4C , wherein reference numeral 200 represents a circuit board, and 300 represents an electrical connector.

Referring to FIG. 5, FIG. 5 shows a second embodiment of the present invention, wherein the same elements as those of the first embodiment are marked with the same reference numerals, and their descriptions are omitted. A slot 42 is arranged on the top of the slot 60 on the mobile phone case 40, and an elastic ear 11 is correspondingly provided at the bottom of the receiving seat 10. When the receiving seat 10 is fully inserted into the mobile phone slot 60, the elastic ear is in a compressed state; When the sliding member 20 is pushed to the right so that the receiving seat 10 is ejected by the curved elastic piece 50, the elastic ear 11 is released through the slot 42 and snapped into it, which prevents the receiving seat 10 from being completely separated from the mobile phone casing.

6A and 6B show the third embodiment of the present invention, a slot 90 is formed on the mobile phone casing 80 to accommodate the user identification card holder 70, and a reed (or other elastic member) 81 is fixed at the bottom of the slot 90 , and the two opposite sides of the mobile phone casing 80 at the top of the slot 90 are respectively provided with a sliding part 82 and a slot 83 . The receiving seat 70 is basically plate-shaped, and has folded edges 71 and 72 on two opposite sides thereof for placing a user identification card. Two ends of the folded edge 71 are respectively provided with elastic ears 74 (engaging means) and a wedge-shaped portion 75 , and one end of the folded edge 72 is provided with an inclined surface 73 .

When the receiving seat 70 is inserted into the mobile phone, the elastic ear 74 snaps into the slot 83 of the casing 80 to prevent the receiving seat 70 from falling out. At this time, the flange 72 of the receiving seat 70 presses the reed 81, and the wedge-shaped part 75 bears against it. Slider 82 . When wanting to take out the receiving seat 70, then push the sliding member 82 along the direction of the arrow with your hand, so that the sliding member 82 pushes the wedge-shaped part 75 of the receiving seat 70, and utilizes the wedge-shaped principle to make the receiving seat overcome the clamping effect of the engaging device, and the receiving seat will be held Seat 70 is pushed out of groove 90 .

When the receiving seat 70 is inserted back into the mobile phone, the inclined surface 73 of the receiving seat 70 can push the slider 82 away, and when the receiving seat 70 is inserted to a fixed position, the elastic ear 74 is inserted into the slot 83 again to be fixed.

Referring to FIG. 7A, 7B, FIG. 7A, 7B show a fourth embodiment of the present invention, wherein the same elements as those of the third embodiment are marked with the same reference numerals, and their descriptions are omitted. On the mobile phone casing 80, another slot 84 is arranged at a predetermined position below the slot 83, and an elastic ear 11 is correspondingly arranged at the bottom of the receiving seat 70 at the same time. When the receiving seat 70 is completely inserted into the mobile phone slot 90, the elastic ear 11 It is in a compressed state; when the wedge-shaped principle is used to push out the receiving seat 70, the elastic ear 11 is released through the slot 84 and snapped into it, so that the receiving seat 70 and the mobile phone casing can be prevented from falling off completely.

The invention can be used in conjunction with the existing mobile phone case and electrical connector, and has a very simple structure. When plugging and unplugging the SIM card, there is no need to remove the battery first, and no other tools are needed. Just push the sliding part to withdraw from the receiving seat, and then directly insert the receiving seat back into the mobile phone for positioning, which is very convenient.
