Referring to FIG. 3 , FIG. 4 and FIG. 6 , in some embodiments, the elastic arm 121 is made of memory alloy material.

Specifically, a memory alloy generally refers to a shape memory alloy, and a shape memory alloy is a material composed of two or more metal elements having a shape memory effect. The shape memory effect of memory alloys is mainly formed by thermoelasticity and martensitic transformation and its inversion. The memory alloy systems found so far include: Au-Cd, Ag-Cd, Cu-Zn, Cu-Zn-Al, etc.

Using the shape memory effect of memory alloy, the elastic arm 121 can be made of memory alloy material. In this example, the thermal elasticity of the memory alloy can be used (the memory alloy is deformed when heated and returns to its original state when the temperature recovers) to connect the wire 14 at the first end 1210 of the elastic arm 121 , and the wire 14 can be connected to the electric drive device 30 . As shown in FIG. 3 , when the elastic arm 121 is powered on, the temperature on the elastic arm 121 will increase, so that the elastic arm 121 will deform. Then, the tray 11 can be pushed by the elastic member 13 to move from the first position to the second position relative to the fixed member 12; as shown in FIG. 6, when the elastic arm 121 is powered off, the temperature on the elastic arm 121 drops, and the elastic The arm 121 will return to the original straight state.

In particular, the embodiment of the present application does not limit the driving method of the elastic arm 121. In addition to using the thermal elasticity of the memory alloy and using the electric driving method, the pseudo-elasticity of the memory alloy (also known as superelasticity, which expresses In order to under the action of external force, the memory alloy has much greater deformation and recovery ability than ordinary metals), for example, the elastic arm 121 is deformed by applying force to the elastic arm 121 by using a pull rod, and the elastic arm 121 can also return to the initial state after the force is stopped. .

In this way, by using the memory alloy material to make the elastic arm 121, the elastic arm 121 is deformed when powered on, and has the ability to recover from deformation after power failure, so that the way of driving the elastic arm 121 to engage and release the card tray 11 is simpler and more feasible. control.

Referring to FIG. 5 and FIG. 6 , in some embodiments, the surface of the card tray 11 facing away from the end plate 120 is a complete plane.

Specifically, the card tray 11 includes an upper surface 112 and a lower surface 113 , wherein the surface of the card tray 11 facing away from the end plate 120 is the lower surface 113 of the card tray 11 . When the card tray 11 is in the first position, the lower surface 113 of the card tray 11 is flush with the surface of the casing 20 of the electronic device 100 as a part of the outer decoration of the electronic device 100 . In particular, the lower surface 113 of the card tray 11 is a complete plane, that is, there is no redundant hole-like structure on the lower surface 113 of the card tray 11 .

In this way, the appearance consistency of the electronic device 100 is ensured, and the increase in the manufacturing cost of the electronic device 100 by adding a waterproof design to the electronic device 100 is avoided.

Referring to FIG. 1 , FIG. 2 and FIG. 3 , the electronic device 100 in this embodiment of the present application includes a casing 20 and the card tray structure 10 of any of the above embodiments. When the card tray 11 is located at the first position, the card tray 11 is accommodated in the casing 20 , and when the card tray 11 is located at the second position, the card tray 11 protrudes out of the casing 20 .

Specifically, the electronic device 100 may be an electronic device such as a mobile phone or a notebook computer, and the casing 20 may be a casing of a mobile phone or a casing of a notebook computer. A receiving groove 21 is formed in the casing 20 for receiving the card tray 11 in the casing 20 or providing space for the movement of the card tray 11 . The card tray structure 10 can be applied to the electronic device 100 to facilitate the user to take out or load the function card.

As shown in FIG. 2, when the user does not need to take out or load the function card, the card tray 11 is accommodated in the housing 20 through the receiving slot 21, and the card tray 11 is at the first position at this time; as shown in FIG. 3 As shown, when the user needs to take out or load the function card, the card tray 11 can be driven to move to protrude from the casing 20 by means of electric drive, and the card tray 11 is located at the second position.

In this way, when the user does not need to use the card tray 11, the card tray 11 is accommodated in the housing 20 through the receiving slot 21, and when the user needs to use the card tray 11, the card tray 11 can be moved from the first position in the receiving slot 21 to protrude out of the housing 20 . In this way, the card tray structure 10 and the electronic device 100 are formed as a whole, so that the structure of the electronic device 100 is more compact.

Referring to FIG. 2 and FIG. 7 , in some embodiments, the electronic device 100 includes an electric driving device 30 . The electric driving device 30 is used to drive the fixing member 12 to loosen from the card tray 11 when the card tray 11 is located at the first position, so that the elastic member 13 drives the card tray 11 to move to the second position.

Specifically, the electronic device 100 is further provided with an electric drive device 30 , and the electric drive device 30 energizes the elastic arm 121 through the wire 14 arranged on the first end 1210 of the elastic arm 121 to drive the elastic arm 121 to deform, so that the elastic arm 121 is deformed. When the card tray 11 is in the first position, the hook 1213 on the elastic arm 121 is released from the blocking block 1111 on the card tray 11 . At this time, the elastic member 13 can gradually change from a compressed state to a relaxed state, and the elastic force generated by the compressed state is used to drive the tray 11 to move to the second position, that is, the tray 11 can move to protrude from the casing 20 .

In this way, the card tray 11 can be moved relative to the fixing member 12 between the first position and the second position in an electric manner.

Referring to FIG. 7 , in some embodiments, the electronic device 100 includes a processor 40 , and the processor 40 controls the electric drive device 30 to drive the fixing member 12 to loosen from the card tray 11 according to the trigger instruction.

Specifically, the electronic device 100 further includes a touch display screen 50 . In this example, the user issues a trigger instruction by touching the display screen 50 to make the card tray 11 pop up as follows:

When the user needs to take out the function card or load the function card, the user can issue a trigger instruction to the processor 40 by touching the display screen 50 . After receiving the trigger instruction, the processor 40 controls the electric drive device 30 to start up to energize the elastic arm 121 . At this time, since the memory alloy made of the elastic arm 121 has thermal elasticity, the temperature of the elastic arm 121 rises after power-on, so that the elastic arm 121 is deformed and bent, so that the hook 1213 on the elastic arm 121 and the block 1111 on the tray 11 loose. Then the card tray 11 is driven by the elastic force provided by the elastic member 13 to move relative to the fixing member 12 from the first position to the second position, so that the card tray 11 can be moved to protrude from the casing 20, and the elastic arm 121 is powered off at this time. The elastic arm 121 is restored to the straight state.

After the card tray 11 is ejected out of the casing 20 , the user can easily hold the part of the card tray 11 that protrudes out of the casing 20 , so as to take the card tray 11 out of the casing 20 . After the user completes the operation of taking out the function card or inserting the function card, the card tray 11 can be pushed back into the casing 20 in the correct direction through the receiving groove 21 formed in the casing 20 so that the lower surface 113 of the card tray 11 and the The surface of the housing 20 is flush. In the process of pushing back, the elastic arm 121 will be deformed by the force exerted by the user. After the user stops applying the force, the elastic arm 121 will return to a straight state to limit the position of the card tray 11 .
