The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
The embodiment of the disclosure provides a card holder. Fig. 1 is a first schematic structural diagram of a card socket according to an exemplary embodiment. As shown in fig. 1, the cartridge includes:
a card socket housing 101 having a card slot for receiving the card holder 102;
a connector 108 fixed on the card holder housing;
card support ejector pin includes: a first movable end 103 connected to the connecting member 108 and capable of rotating around the connecting member 108;
a memory metal 104 connected to the first movable terminal 103;
the memory metal 104 is used for contracting under the power-on state and drawing the first movable end 103 to act on the card holder, so that the card holder moves from the inside of the card slot to the outside of the card slot.
In the embodiment of the disclosure, the clamping groove of the clamping seat shell is used for accommodating the clamping support. The card holder is used for placing a card. The card can be various cards with different functions. For example, the card includes a memory card for storing information or a Subscriber Identity Model (SIM) card for identification.
The cassette shell is formed by metal, alloy or composite metal.
The connecting piece can be fixed on the inner surface of the top of the clamping groove of the clamping seat shell. It should be noted that, the connecting element may be fixed on the inner surface of the top of the card slot by welding, and may also be fixed on the inner surface of the top of the card slot by a threaded connection, which is not limited in the embodiments of the present disclosure.
The connecting piece is used for connecting the card support ejector rod. The connecting piece is a movable connecting piece. Such as a hinge or a variety of movable connectors.
The card support ejector rod comprises a connecting part, the connecting part is connected with the connecting piece, and the first movable end is connected with the connecting piece through the connecting part. In the embodiment of the disclosure, the connecting part is movably connected with the connecting piece. When external force acts on the first movable end, the first movable end can rotate around the connecting piece.
In the embodiment of the present disclosure, the first movable end directly acts on the card holder located in the card slot to move the card holder out of the card slot, and the first movable end indirectly acts on the card holder located in the card slot to move the card holder out of the card slot.
In an embodiment of the disclosure, the memory metal traction first movable end includes: the memory metal pulls the first movable end to approach the opening of the clamping groove; or the memory metal pulls the first movable end to be far away from the opening of the clamping groove.
In some embodiments, the first movable end contacts a card holder located within the card slot. That is to say, when the card support is required to be moved out of the clamping groove, the first movable end can be directly pulled through the memory metal, so that the first movable end is close to the opening of the clamping groove, the card support in contact with the first movable end can also be close to the opening of the clamping groove, and the movement out of the card support is realized.
It should be noted that the first movable end may be adapted to the bottom of the slot. When the card support is correctly installed in the card slot, the first movable end is partially embedded into the bottom of the card slot, so that the first movable end can be prevented from sliding in the card slot, and the first movable end is ensured to be stably positioned in the bottom of the card slot.
Further, the cross section of the end part of the first movable end is in a step shape. That is, the diameter of the top of the first movable end is smaller than the portion of the card holder ejector rod other than the first movable end. So, can realize that first expansion end imbeds the bottom at the draw-in groove steadily.
In other embodiments, the card-holder eject lever may further include a second movable end, and the second movable end and the first movable end are respectively connected to opposite ends of the connecting portion. The second movable end is positioned in the clamping groove and is contacted with the card support when the card support is positioned in the clamping groove.
That is to say, when the card holder needs to be moved out of the card slot, the memory metal can pull the first movable end to make the first movable end far away from the opening of the card slot. At this moment, the second movable end opposite to the first movable end in movement direction is close to the opening of the clamping groove, so that the clamping support in contact with the second movable end can also be close to the opening of the clamping groove, and the shifting-out of the clamping support is realized.
The memory metal can change the internal crystal structure based on the temperature change, and further generates the deformation on the appearance. For example, memory metals shrink above a certain temperature; the memory metal recovers the original shape below a certain temperature. The temperature of the memory metal is changed by electrifying the memory metal, so that the length of the memory metal in an electrified state is different from that in a power-off state. The memory metal may be formed of a nickel titanium alloy material.
It should be noted that the length of the memory metal after contraction in the power-on state is smaller than the length of the memory metal after expansion in the power-off state. When the memory metal is switched from the power-off state to the on-off state, the length contraction of the memory metal can generate acting force, and then the acting force generated by the memory metal pulls the first movable end connected with the memory metal to be close to or far away from the opening of the clamping groove, so that the card support can be moved out.
For example, when first expansion end contact card held in the palm, be close to towards the draw-in groove opening through first expansion end, and then first expansion end can promote the card to hold in the palm and be close to the draw-in groove opening, has realized shifting out of card support. For another example, when the second movable end opposite to the first movable end in the moving direction contacts the card holder, the first movable end is far away from the opening of the card slot, so that the second movable end is close to the opening of the card slot, and the second movable end can push the card holder to be close to the opening of the card slot, thereby realizing the moving-out of the card holder.
The card seat can also comprise a locking mechanism and a detection spring plate. The detection elastic sheet is used for detecting whether the card support is installed in the card slot. The locking mechanism is used for locking the card holder when the card holder is installed in the card slot, so that the card holder is fixed in the card slot.
In the embodiment of the disclosure, the first movable end directly acts on the card holder located in the card slot, that is, when the first movable end contacts with the card holder, the first movable end can be drawn by the memory metal to approach the opening of the card slot, so as to move out the card holder; the first movable end indirectly acts on the card support positioned in the card slot, namely the first movable end is not contacted with the card support, and when the second movable end is contacted with the card support, the first movable end can be pulled by the memory metal to be far away from the opening of the card slot so as to realize the moving-out of the card support.
As shown in fig. 2 and 3, in the related art, an opening 12 is formed in a housing of a terminal device, and a thimble 11 is inserted into the opening 12 to push the thimble 11 to push a push rod, so that the push rod pushes a card holder ejecting rod, and the card holder ejecting rod ejects a card holder installed in a card holder. Therefore, the existing solution for removing the card holder needs a thimble and also needs to open a hole on the housing of the terminal device.
Based on this, the embodiment of the present disclosure provides that the memory metal is contracted by electrifying, so that the memory metal can draw the first movable end connected with the memory metal to move. If the card support is positioned in the card slot, the card support can move from the inside of the card slot to the outside of the card slot under the action of the first movable end. Therefore, the acting force generated by the memory metal power-on contraction is used as the power for drawing the card support ejection rod, the card support can be moved out without the help of an auxiliary tool, and the operation is more convenient and faster. In addition, the hole for the ejector pin does not need to be formed in the shell of the terminal equipment, the hole-free design of the shell of the terminal equipment is facilitated, the integrity of the terminal equipment is improved, and the situation that dust accumulation or water resistance is poor due to the hole opening is reduced. In addition, the embodiment of the disclosure does not need a push rod and a mechanical structure matched with the push rod and the card support ejection rod, so that the space occupied by the card seat in the terminal device can be reduced, and the space utilization rate is improved.
In some embodiments, as shown in fig. 1, the side of the cartridge housing is provided with a guide slot;
the memory metal is in a bending state in the guide groove and contracts along the guide groove in a power-on state.
That is, the embodiments of the present disclosure may guide the contraction direction of the memory metal in the energized state through the guide groove so that the memory metal can be contracted in a predetermined direction.
The position of the guiding groove on the card seat shell is arranged according to the position of the memory metal. For example, when the memory metal surrounds the outer surface of the first side of the cartridge housing, the guide slot may be provided on the outer surface of the first side; when the memory metal surrounds the first side surface of the card seat shell and the third side surface adjacent to the first side surface, a plurality of guide grooves are arranged on the first side surface and the third side surface respectively, and the embodiment of the disclosure is not limited.
In the embodiment of the present disclosure, the groove wall of the guiding groove may be smooth. So, when memory metal contracts along the guiding groove, can reduce the friction between memory metal and the cell wall, be favorable to the memory metal to contract for the effort maximum that the memory metal contraction produced acts on first expansion end, can improve the drive force that first expansion end acted on the card support.
It should be noted that the guide groove may be a broken line guide groove having a bending point or a bending guide groove. Thus, the memory metal can be guided to contract in the bending direction of the bending part through the broken line guide groove and the bending guide groove.
In the embodiment of the present disclosure, the groove wall of the guide groove may be used to guide the contraction direction of the memory metal, and a track may be further disposed in the guide groove to guide the contraction direction of the memory metal through the track.
In some embodiments, as shown in fig. 4, the first movable end 103 extends out of the cartridge housing 101 from a first side of the cartridge housing 101;
the memory metal 104 is fixed on the second side surface of the card holder shell 101, bypasses the first side surface and the third side surface of the card holder shell 101, and is connected with the first movable end 103 on the first side surface;
wherein the second side surface is the opposite side surface of the first side surface; the third side connects the first side and the second side.
In the embodiment of the disclosure, the shape of the memory metal is strip-shaped, and the memory metal can be connected with the first movable end of the first side surface around the first side surface and the third side surface. So, through the stiff end with memory metal connection cassette casing with first expansion end setting in the different sides of cassette casing, can prolong memory metal's length, and then make memory metal can produce bigger effort through length contraction and pull first expansion end motion to improve the power that first expansion end acted on the card support.
Furthermore, the fixed end and the first movable end of the memory metal connecting clamping seat shell are arranged on different sides of the clamping seat shell, and the installation stability of the memory metal can be ensured. For example, when two or more sides of the card seat shell are provided, the memory metal can be pulled among the memory metals on the sides by winding the first side, the second side and the third side, so that the phenomenon of movement of the memory metal is reduced, and the memory metal can be stably installed.
In some embodiments, as shown in fig. 4, the memory metal has two connection ends, a first connection end 104a and a second connection end 104 b. The memory metal is fixed on the second side surface of the card seat shell, and the memory metal is connected with the first movable end on the first side surface, and the memory metal card seat can include: the first connection end 104a and the second connection end 104b of the memory metal are both fixedly connected to the second side surface of the cassette housing 101, and the connection portion between the first connection end 104a and the second connection end 104b is connected to the first movable end 103 by surrounding the first movable end 103.
Therefore, the clamping seat shell is connected with the first connecting end, the second connecting end is connected with the first movable end, the length of the memory metal can be doubled, the length of the memory metal can be prolonged to the maximum degree, and the acting force for drawing the first movable end is improved. Meanwhile, for supplying power to the memory metal connected with the first movable end, the first connecting end and the second connecting end of the memory metal are fixed on the same side face of the clamping seat shell in the embodiment of the disclosure, and the power supply end can be directly arranged on the same side face of the clamping seat shell, so that the memory metal can be supplied with power more conveniently.
In some embodiments, the first movable end extends out of the cartridge housing from a first side of the cartridge housing;
the memory metal is connected with the clamping seat shell on the first side face, and the distance between the connecting position of the memory metal and the clamping seat shell and the opening of the clamping groove is smaller than the distance between the first movable end and the opening of the clamping groove.
In the embodiment of the disclosure, the memory metal may be located not only on different sides of the card socket housing, but also on the same side of the card socket housing as the first movable end. Therefore, the memory metal of the embodiment of the disclosure is more flexible in arrangement position, and can meet the requirements of different arrangement scenes.
It should be noted that the distance between the connection position of the memory metal and the card socket shell and the opening of the card socket is smaller than the distance between the first movable end and the opening of the card socket. When the first movable end and the memory metal are arranged, the opening of the clamping groove far away from the first movable end can be arranged, and the opening of the clamping groove close to the second movable end is arranged. Therefore, the length of the memory metal can be increased, and the acting force for drawing the first movable end is improved.
When the memory metal and the first movable end are arranged on the same side, in order to further increase the length of the memory metal, the first connecting end and the second connecting end of the memory metal can be fixed on the first side surface of the card seat shell and are arranged close to the opening of the card slot, and the part between the first connecting end and the second connecting end is connected with the first movable end by winding around the first movable end. Therefore, the second connecting end is connected with the first movable end relative to the first connecting end connected with the clamping seat shell, so that the length of the memory metal can be doubled, and the length of the memory metal can be prolonged to the maximum extent.
