The smart card tray 10 fixing device of the utility model is provided with a base plate 20 and a bracket 30, the bracket 30 is located on the base plate 20, and forms a slot with a socket with the base plate 20, and the card tray 10 is connected from the base plate 20. The socket is inserted in the slot; and, a positioning protrusion 40 is set on the card tray 10, and a position corresponding to the positioning protrusion 40 is provided on the bracket 30 to accommodate the positioning protrusion 40. The card position 50, through the cooperation of the positioning protrusion 40 and the card position 50, the card tray 10 is fixed and disassembled. At the same time, an elastic member 60 connected and fixed with the bracket 30 is also arranged in the slot, and the elastic member 60 can be placed in the slot. When the positioning protrusion 40 is disengaged from the card position 50, the card holder 10 is pushed out of the slot from the socket to realize card removal. The utility model does not need other tools in the process of loading and unloading the card, and can be completed by manually pressing the card holder 10, which is very convenient and saves product cost at the same time.

It can be understood that the smart card tray 10 fixing device is mainly used to be installed in electronic equipment to realize automatic card removal. The structure that the smart card holder 10 fixing device is installed in the electronic equipment can be realized by the following structure, as shown in Figure 5, in one embodiment, the smart card holder 10 fixing device also includes a casing, the bottom plate 20 and The bracket 30 is located in the casing 70 , the casing 70 , the bottom plate 20 and the bracket 30 cooperate to form the slot, and the socket 71 of the slot is disposed on the casing 70 . In practical application, the casing 70 can be regarded as the casing of the electronic equipment, and the bottom plate 20 is the main board of the electronic equipment. The outer surface is flush to ensure a neat and beautiful appearance. Moreover, the card tray 10 is adapted to the size of the socket 71 on the casing 70 .

It can be understood that the above-mentioned bracket 30 can be implemented in various forms, and will not be introduced here one by one. In this embodiment, a preferred implementation mode is selected to describe the structure of the bracket 30 in detail. Referring to FIG. 2 to FIG. 10 , the bracket 30 includes a first elastic arm 31, a second elastic arm 32 arranged oppositely and in parallel, and a connecting arm 33 that connects and fixes the first elastic arm 31 and the second elastic arm 32, and the connecting arm 33 is located on the The first elastic arm 31 and the second elastic arm 32 face away from the side of the bottom plate 20 and are away from the end of the first elastic arm 31 and the second elastic arm 32 close to the socket 71; the elastic member 60 is provided on the first elastic arm 31 and/or the second elastic arm 32 . After assembly, the first elastic arm 31 is opposite to the second elastic arm 32 , and the connecting arm 33 is opposite to the bottom plate 20 to enclose the slot and realize the positioning of the card tray 10 in the up, down, left, and right directions. Moreover, the first elastic arm 31 and the second elastic arm 32 are only connected and fixed to the bottom plate 20 at the position corresponding to the connecting arm 33, and a section close to the socket 71 is not fixed, so that the first elastic arm 31 and the second elastic arm 32 relies on the elasticity of its material and has a certain deformation space. It is mainly used to avoid being blocked by the first elastic arm 31 and the second elastic arm 32 when taking the card tray 10, so that it is difficult to make the card tray 10 eject.

Based on this embodiment, referring to FIG. 2 to FIG. 10 , further, the end of the first elastic arm 31 facing away from the bottom plate 20 is provided with a first lug 310 , and the second elastic arm 32 is facing away from the One end of the bottom plate 20 is provided with a second lug 320, the position of the first lug 310 and the second lug 320 are corresponding, and are located between the first elastic arm 31 and the second elastic arm 32; The positions are respectively provided on the first lug 310 and the second lug 320, and the positioning protrusion 40 on the card holder 10 corresponds to the locking position on the first lug 310 and the second lug 320. 50 position and quantity settings.
