[0038] Please also read Figures 1 to 5An embodiment of the present application provides a mobile terminal, which may be a mobile phone (e.g., a relatively large rugged mobile phone) or a tablet computer. The mobile terminal includes a terminal housing 2 and a card tray 100. The mobile terminal also includes other conventional functional components such as a battery and a main control circuit board. Since they are not related to the invention, they are not described here.

[0039] The terminal housing 2 includes a frame and a back plate (not shown). The frame and the back plate can be formed separately and then combined; or, in some embodiments, the frame and the back plate can also be formed in one piece. The frame includes a pair of short frame bodies 21 and a pair of long frame bodies 23 connected to each other. The long frame body 23 or the short frame body 21 is provided with a first slot body 210, a second slot body 220 and a third slot body 230. Figure 2 shown.

[0040] The first slot body 210 is a through slot, the length and width of the second slot body 220 are larger than those of the first slot body 210 and form a step structure for limited insertion with the first slot body 210, and the third slot body 230 is arranged on the side of the length direction of the second slot body 220 and is connected to the second slot body 220.

[0041] The card tray 100 includes an inner bracket 110 and an outer bracket handle 120 that are connected to each other. The inner bracket 110 is provided with a plurality of card slots for installing function cards. The function card can be a SIM card or an SD card. For example, there are three card slots, which can accommodate one SD card and two SIM cards. The outer bracket 120 is matched with the step structure. The inner surface of the outer bracket 120 near the third slot body 230 is provided with a notch 121. The notch 121 is used to allow a prying tool (or a fingernail) to extend from the third slot body 230 and abut against the inner surface of the outer bracket 120 provided with the notch 121 to pry the outer bracket 120 out of the step structure.

[0042] When fingernails are used to eject the card, there is no need to use a card ejection tool. When a prying tool is used to eject the card, there are relatively more optional prying tools, including various thin or pointed tools, such as blades, scissors, etc. Compared with the existing structure of ejection needles, the card ejection tool selection is wider, and the card can even be ejected by hand, which is more convenient to operate.

[0043] The first groove body 210 , the second groove body 220 and the third groove body 230 are all waist-shaped grooves, which are easy to process. The length of the third groove body 230 can be less than or equal to the length of the second groove body 220 .

[0044] like Figure 3 As shown, in a specific embodiment of the present application, the long frame body 23 may include a plastic frame bar 231 and a metal frame bar 232 fixed on the plastic frame bar 231 , the plastic frame bar 231 is provided with a first groove body 210 , and the metal frame bar 232 is provided with a second groove body 220 and a third groove body 230 .

[0045] The second groove body 220 is a through groove, and the third groove body 230 is a blind groove with a bottom wall. When the prying tool is inserted into the groove, it contacts the metal bottom wall to avoid scratching the plastic frame strip 231 .

[0046] The angle between the side wall and the bottom wall of the third groove body 230 is greater than 90 degrees, that is, the third groove body 230 has a slope transition, which is convenient for guiding the prying tool to extend in and lift up the inner surface of the groove 121 with the top edge of the side wall of the third groove body 230 as a fulcrum in a lever principle mode.

[0047] like Figure 4 and Figure 5 As shown, the mobile terminal provided in the embodiment of the present application further includes a heat dissipation cavity 30 , a projector 9 , a heat dissipation block 7 , and a blower 4 .

[0048] The heat dissipation cavity 30 is connected to the frame, and the heat dissipation cavity 30 has an assembly opening 31, an air inlet channel 32, and an air outlet channel 33 that are connected to each other. The projector 9 is arranged in the terminal housing 2 and is located outside the heat dissipation cavity 30. The heat dissipation block 7 is connected to the projector 9 and is sealed at the assembly opening 31 of the heat dissipation cavity 30, and is used to absorb the heat generated by the projector 9 when working. The blower 4 is arranged in the heat dissipation cavity 30 and is sealed by the heat dissipation block 7.
