The card support push rod 200 is disposed in the housing, and the card support push rod 200 is movable, that is, the card support push rod 200 is movable relative to the housing, and when the card support 100 needs to extend out of the housing, the card support push rod 200 is used to drive the card support 100 to extend out of the opening of the card support accommodating cavity.
The driving device 300 is disposed in the housing, and the driving device 300 may include at least one of a motor, a cylinder, a hydraulic cylinder, a shape memory alloy member, and a piezoelectric member. Wherein: the motor has the characteristics of small volume, high efficiency and convenient control; the air cylinder and the hydraulic cylinder have the characteristics of large output force and stable and reliable performance; the shape memory alloy part is made of shape memory alloy, the shape can be changed when the temperature of the shape memory alloy part is changed, namely, the shape memory alloy part is subjected to thermal deformation, and the shape memory alloy part has the characteristics of simplicity in installation and environmental friendliness; the piezoelectric element can also change shape after being electrified, and has the characteristics of simple installation and environmental protection. The embodiment of the present application does not limit the specific manner of the driving device 300. Optionally, the driving device 300 includes a vibration motor 310 and a magnetic assembly 320, the vibration motor 310 not only can provide a driving force, but also has a vibration function, and secondly, the vibration motor 310 has the characteristics of large vibration force, small volume and low mechanical noise; the magnetic assembly 320 has an overload protection function, and the non-contact structure has the characteristics of small abrasion and simple structure. The magnetic assembly 320 is connected to the card holder push rod 200, the magnetic assembly 320 includes a first magnetic member 321 and a second magnetic member 322, at least one of the first magnetic member 321 and the second magnetic member 322 is an electromagnetic member, optionally, the first magnetic member 321 may be an electromagnetic member, the second magnetic member 322 may be an electromagnetic member, or both the first magnetic member 321 and the second magnetic member 322 may be electromagnetic members, which is not limited in this application embodiment. The first magnetic member 321 moves between a first position and a second position, when the first magnetic member 321 is located at the first position, the vibration motor 310 is connected to the first magnetic member 321, and the vibration motor 310 can drive the card holding push rod 200 to move through the first magnetic member 321; with the first magnetic member 321 in the second position, the vibration motor 310 is separated from the first magnetic member 321.
Specifically, when a user needs to extend the card holder 100 from the opening of the card holder accommodating cavity, the electromagnetic element may be energized, at this time, a magnetic repulsion force is generated between the first magnetic element 321 and the second magnetic element 322, so as to drive the first magnetic element 321 to move in a direction away from the second magnetic element 322, when the first magnetic element 321 moves to the first position, the vibration motor 310 is connected to the first magnetic element 321, at this time, the vibration motor 310 operates, the vibration motor 310 can drive the card holder push rod 200 to move through the first magnetic element 321, so as to push the card holder 100 out of the card holder accommodating cavity, so that the card holder 100 does not need to be inserted into the card taking hole by means of a card taking needle or a similar tool to apply a driving force to extend the card holder 100, and therefore, by using this arrangement, the card holder 100 can be taken out more simply and conveniently. When the electromagnetic element is powered off, a magnetic attraction force is generated between the first magnetic element 321 and the second magnetic element 322, so as to drive the first magnetic element 321 to move toward the direction close to the second magnetic element 322, and when the first magnetic element 321 moves to the second position, the vibration motor 310 is separated from the first magnetic element 321, and the power of the vibration motor 310 cannot be transmitted to the card holder 100, so that the vibration motor 310 can work alone. Therefore, the embodiment of the application can solve the problem that the card holder 100 of the existing electronic equipment is complex to take out. In addition, the vibration motor 310 may provide power when the card holder 100 extends out of the card holder accommodating cavity, or may be a structure for implementing a vibration function of the electronic device, so that the embodiment may implement multiplexing of the structure, thereby simplifying the structure of the electronic device.

The driving device disclosed in the embodiment of the present application may further include a transmission member, the transmission member is connected to the vibration motor 310, and when the first magnetic member 321 is located at the first position, the vibration motor 310 may be connected to the first magnetic member 321 through the transmission member; with the first magnetic member 321 in the second position, the transmission member may be separated from the first magnetic member 321. However, the driving device 300 with such a structure is complicated and occupies a large space. Therefore, in an alternative embodiment, the vibration motor 310 has a driving shaft 311, the driving shaft 311 is provided with a spiral driving surface, and when the first magnetic member 321 is located at the first position, the spiral driving surface contacts with the first magnetic member 321, and when the vibration motor 310 is operated, the driving shaft 311 rotates, accordingly, the driving force output by the driving shaft 311 is transmitted to the first magnetic member 321 along the spiral driving surface, and the vibration motor 310 drives the first magnetic member 321 to move through the spiral driving surface. The driving device 300 with such a structure according to the embodiment of the present application does not need to additionally provide a transmission member, thereby being beneficial to improving the space utilization rate inside the electronic device.
The center of gravity of the driving shaft 311 and the rotation center line of the driving shaft 311 may be disposed to coincide with each other, and if such a structure is adopted, the vibration effect is weak and the user may hardly feel the vibration of the electronic apparatus when the vibration motor 310 is operated. Therefore, in a further alternative embodiment, the center of gravity of the driving shaft 311 is offset from the rotation center line of the driving shaft 311, that is, the driving shaft 311 has an asymmetric structure, and when the vibration motor 310 operates, the driving shaft 311 with the asymmetric structure further enhances the vibration effect of the whole vibration motor 310, thereby enhancing the vibration effect of the whole electronic device.
In a further embodiment, the outer peripheral surface of the driving shaft 311 includes a first arc surface 311a and a second arc surface 311b, and if the radius of the first arc surface 311a is smaller than or equal to the radius of the second arc surface 311b, since the radius of the first arc surface 311a is smaller, if a spiral driving surface is to be disposed on the first arc surface 311a, the strength problem caused thereby needs to be overcome, which may cause great design difficulty. Therefore, optionally, the radius of the first arc surface 311a is larger than that of the second arc surface 311b, and at this time, the radius of the first arc surface 311a is larger, so that the spiral driving surface is conveniently arranged on the first arc surface 311a, and the design difficulty can be reduced.
Optionally, the outer peripheral surface of the driving shaft 311 further includes a third arc surface 311c, the first arc surface 311a and the third arc surface 311c are located on the same side of the driving shaft 311, the radius of the third arc surface 311c is greater than that of the second arc surface 311b, the radius of the third arc surface 311c is smaller than that of the first arc surface 311a, and the third arc surface 311c is connected to the first arc surface 311a through the spiral driving surface. In the embodiment of the present application, by providing the third arc surface 311c, the portion of the driving shaft 311 provided with the spiral driving surface is thicker, so that the strength of the driving shaft 311 can be improved; secondly, the weight of the drive shaft 311 can be increased, so that the center of gravity of the drive shaft 311 can be more easily shifted from the rotation center line of the drive shaft 311.
In an alternative embodiment, the magnetic assembly 320 further includes a housing 323 and a base 324, the housing 323 and the base 324 may be base members of the magnetic assembly 320, and can provide a mounting base for other structures of the magnetic assembly 320, the housing 323 is connected to the base 324 and encloses a receiving space, the base 324 is connected to the card holder push rod 200, alternatively, the base 324 and the housing 323 may be provided as an integral structure, or may be provided as a separate structure, and further fixed by welding or the like, which is not limited in this application. The second magnetic member 322 is located in the accommodating space, the housing 323 is provided with a through hole, a first end of the first magnetic member 321 is located in the accommodating space, the first end is opposite to the second magnetic member 322, and a second end of the first magnetic member 321 is matched with the through hole. Specifically, when the electromagnetic element is energized, a magnetic repulsive force is generated between the first magnetic element 321 and the second magnetic element 322, so that the first magnetic element 321 is driven to move, i.e., the second end of the first magnetic element 321 passes through the through hole, and is connected to the vibration motor 310. In the embodiment of the present application, the first magnetic element 321 and the second magnetic element 322 are disposed in the accommodating space defined by the housing 323 and the base 324, so that the first magnetic element 321 moves in a predetermined range in the accommodating space, and a guide is provided for the movement of the first magnetic element 321, so that the entire magnetic assembly 320 operates more stably and reliably.
In an alternative embodiment, the moving direction of the card holder 100 is a first direction, the first magnetic member 321 moves between a first position and a second position along a second direction, and if the included angle between the first direction and the second direction is smaller than 90 ° or larger than 90 °, the contact area between the first magnetic member 321 and the vibration motor 310 (when the driving shaft 311 of the vibration motor 310 is provided with the spiral driving surface, that is, the contact area between the first magnetic member 321 and the spiral driving surface) is smaller, which results in more wear between the two. Therefore, optionally, the second direction is perpendicular to the first direction, so as to alleviate the wear of the vibration motor 310 or the first magnetic member 321.
In a further alternative embodiment, the vibration motor 310 has a driving shaft 311, the axial direction of the driving shaft 311 is parallel to the first direction, that is, the direction of the driving force output by the vibration motor 310 is parallel to the moving direction of the card holder 100, and in the case that the first magnetic member 321 is located at the first position, the driving shaft 311 drives the first magnetic member 321 to move, so that the driving force output by the vibration motor 310 is transmitted to the first magnetic member 321 as much as possible, thereby driving the card holder push rod 200 to move, and further improving the working efficiency of the vibration motor 310.
In an alternative embodiment, the electronic device further includes a rotating member 400, and the rotating member 400 is rotatably connected to the housing, and the connection manner may be a hinge, and the like, which is not particularly limited in this embodiment. One end of the rotating member 400 is connected to the card-holding push rod 200, optionally, the rotating member 400 and the card-holding push rod 200 may be provided in a split structure, which facilitates maintenance and replacement when the rotating member 400 or the card-holding push rod 200 is damaged; further alternatively, a groove is formed at a third end of the card-holding push rod 200, and one end of the rotation member 400 is engaged with the groove. The other end of the rotating member 400 is a force applying end, and the card-supporting push rod 200 drives the rotating member 400 to rotate when the first magnetic member 321 is located at the first position. Specifically, when the vibration motor 310 drives the card holder push rod 200 to move along the first direction through the first magnetic member 321, the card holder push rod 200 drives the rotation member 400 to rotate, and the force applying surface of the rotation member 400 acts on the bottom of the card holder 100, so as to push the card holder 1000 to extend out of the card holder accommodating cavity. In the embodiment of the application, since the rotating member 400 is rotatably connected with the housing, the rotation is flexible, and the card holder 100 is pushed to extend by the rotating member 400 more sensitively and accurately; secondly, the rotation member 400 acts on the bottom of the card holder 100, so that the driving force applied to the card holder 100 is relatively uniform and does not incline during the movement.
Alternatively, the rotation member 400 includes a rotation body 410 and a connection shaft 420, the connection shaft 420 may be fixedly connected with the housing, the rotation body 410 is provided with a connection hole located at a middle position of the rotation body 410, and the rotation body 410 is connected with the connection shaft 420 through the connection hole. Compared to the scheme in which the rotating body 410 and the connecting shaft 420 are rotated together, the scheme in which only the rotating body 410 is rotated can reduce the weight of the rotating part of the rotating member 400, thereby improving the stability of the rotating member 400 when rotating.
Further optionally, the electronic device disclosed in this application embodiment further includes a detection piece 500, and the detection piece 500 is disposed in the housing, and optionally, the detection piece 500 may be a detection elastic piece, and the specific structure of the detection piece is not limited in this application embodiment. When the card support push rod 200 drives the card support 100 to extend out of the opening of the card support accommodating cavity, the detection piece 500 is separated from the card support 100; when the user inserts the card holder 100 into the card holder receiving cavity, the sensing member 500 comes into contact with the card holder 100. The state of the card holder 100 can be known in time through the detection piece 500, and the user experience is further improved.
The third end of the card-holding push rod 200 is connected to the rotating member 400, and at this time, if the connection position between the magnetic assembly 320 and the card-holding push rod 200 is far away from the third end, the acting force applied to the card-holding push rod 200 from the magnetic assembly 320 has a large moment arm, which causes the card-holding push rod 200 to be easily bent. Therefore, the magnetic assembly 320 can be connected to the third end of the card-holding push rod 200, and when the first magnetic element 321 is located at the first position, the vibration motor 310 drives the card-holding push rod 200 to move along the first direction through the first magnetic element 321, and the third end of the card-holding push rod 200 drives the rotating member 400 to rotate.
Optionally, the electronic device disclosed in the embodiment of the present application further includes a circuit board 600, and the driving device 300, the rotating member 400, the detecting member 500, and the like may be disposed on the circuit board 600, at this time, the circuit board 600 may not only supply power to the driving device 300, but also be used to fix the structures of the driving device 300, the rotating member 400, the detecting member 500, and the like, so that the structural components disposed in the electronic device are more stable and compact; further, the base 324 may be provided with contact terminals, and the circuit board 600 is electrically connected with the contact terminals of the base 324 through the lead wires 610, and the lead wires 610 move as the first magnetic member 321 moves between the first position and the second position.
The electronic device disclosed in the embodiment of the present application may be an electronic device such as a smart phone, a tablet computer, an electronic book reader, a wearable device (e.g., a smart watch), and an electronic game machine, and the kind of the electronic device is not particularly limited in the embodiment of the present application.
