Problems solved by technology
After the SD card 300 is inserted into the SD card slot 200, the mobile phone falls towards the opening direction of the SD card slot 200, and the SD card 300 of some mobile phones is easy to break away from the SD card slot 200, which will cause the roller and drop performance of the mobile phone to be significantly reduced, up to less than design requirements
For the user, it will lead to the damage of the reading and writing function of the SD card after it falls, and then cause various abnormalities such as the inability to play MP3, the inability to save photos and photos, and the inability to view files in the SD card 300, which affects the use of the user.
[0004] Therefore, the existing technology still needs to be improved and developed

Embodiment Construction
[0020] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, and the described specific embodiments are only used to explain the present invention, and are not intended to limit the specific embodiments of the present invention.
[0021] The invention discloses a built-in SD card anti-falling structure, such as figure 2 combine image 3 and Figure 4 As shown, the anti-falling structure is arranged on the PCB board of the mobile phone. An SD card slot 210 is disposed on the PCB 110 , and the SD card slot 210 is used for accommodating an SD card 310 . Preferably, the SD card slot 210 can be welded on the PCB 110 by welding. The SD card 310 is placed in the SD card slot 210, the SD card slot 210 is provided with a shrapnel type buckle, the SD card 310 is provided with a buckle slot adapted to the buckle, and the SD card 310 and the SD card slot 210 are fixed through the buckle groove and the buckle...

The invention discloses a built-in type SD (Secure Digital) card falling preventing structure, which is arranged on a mobile telephone PCB (Printed Circuit Board), wherein an SD card groove is arranged on the PCB and is used for holding an SD card; a groove is arranged outside the SD card groove opening direction on the PCB; a movable post for abutting the SD card margin is arranged in the groove; a spring for facilitating the moving of the movable post along the vertical direction is sleeved on the movable post; a fixed seat for placing of the spring is arranged in the groove; and a holding cavity for holding the movable post is arranged at the bottom of the fixed seat. According to the invention, the movable post for abutting the SD card margin is arranged on the mobile telephone PCB, thus the falling of the SD card from the SD card groove is effectively prevented, the roller and falling performances of the mobile telephone is improved, and the abnormities that MP3 cannot play, shooting images cannot be saved, 300 kinds of files in the SD card cannot read and the like caused by damage on the reading/writing function of the SD card are prevented.
Description
technical field [0001] The invention relates to the field of mobile phones, and more specifically, relates to a built-in SD card anti-dropping structure. Background technique [0002] In the prior art, the SD card is fixed by the elastic buckle of the SD card slot to prevent the SD card from falling off from the SD card slot. Usually, the user inserts the SD card into the SD card slot by pressing the SD card, and then ejects the SD card from the SD card slot by pressing the SD card. For the SD card slot, the pressing force is clearly regulated, and SD card slot manufacturers are also very concerned about this indicator. However, when the SD card is in the SD card slot, the force to drag the SD card out of the SD card slot directly, because there is no clear regulation, so the consistency of the dragging force of the SD card in the current SD card slot from the SD card slot is too poor : Some SD card slot specifications do not have this indicator; and some SD card slot spec...
