Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of electronic devices, and particularly relates to an electronic device. BACKGROUND

[0002] In the related art, a data card such as a SIM card or a TF card needs to be carried by a card holder body, and the card holder body carrying the data card needs to be inserted into a card seat of a card holder structure, and the data card is supported and fixed in the electronic device by the card holder body. During the use of the electronic device, the user often needs to replace the data card arranged in the electronic device, and thus needs to take out the card holder body from the card seat. In the current process of taking out the card holder body, the user needs to use a thimble or a similar auxiliary tool to push out part or all of the card holder body. When the electronic device adopting the related technology is used to perform the card holder ejection operation, a thimble needs to be additionally configured, and the thimble is usually arranged separately from the electronic device, which makes it difficult to find the thimble when the card holder ejection operation is performed, and thus the card holder ejection operation is inconvenient. SUMMARY

[0003] The present application aims to provide an electronic device, which at least solves the technical problem of inconvenient card holder ejection operation of the electronic device in the related art.

[0004] To solve the above technical problem, the present application is implemented as follows:

[0005] In a first aspect, an electronic device is provided, comprising:

[0006] A support mechanism comprising a first support, a second support, and a rotating assembly, the first support and the second support being rotatably connected by the rotating assembly;

[0007] A card holder mechanism comprising a card seat, a card holder body, and a push rod, the card seat being arranged on the first support and configured to accommodate the card holder body, the first end of the push rod extending into the card seat, and the second end of the push rod extending out of the card seat;

[0008] An ejection mechanism being in transmission connection with the rotating assembly, when the rotating assembly rotates, the ejection mechanism pushes the second end of the push rod to move or rotate, so that the first end of the push rod pushes out the card holder body.

[0009] In the electronic device provided by the present application, the ejection mechanism is movably connected with the rotating assembly, so that the rotating assembly can drive the ejection mechanism to push the push rod to move or rotate by pushing the rotating assembly to rotate, and the push rod can push out the card holder body from the card seat. Therefore, without an additional thimble arranged separately from the electronic device, the card holder body can be pushed out of the card seat, which facilitates the user to perform the card holder body taking-out operation and facilitates the user to replace the data card carried by the card holder body.

[0026] The following will be described in detail Figures 1 to 5 The electronic device according to the embodiments of the present application is described.

[0027] As Figure 1 and Figure 2As shown, the electronic device provided by the embodiment of the present application comprises a supporting mechanism 1, a card holder mechanism 2 and an ejection mechanism 3. The supporting mechanism 1 is used for supporting a display screen. The supporting mechanism 1 comprises a first support 11, a second support 12 and a rotating assembly 13. The first support 11 and the second support 12 are rotatably connected through the rotating assembly 13. The card holder mechanism 2 comprises a card holder 21, a card holder body and a push rod 23. The card holder 21 is arranged on the first support 11 and is used for accommodating the card holder body. The first end of the push rod 23 extends into the card holder 21, and the second end of the push rod 23 extends out of the card holder 21. The ejection mechanism 3 is in transmission connection with the rotating assembly 13. When the rotating assembly 13 rotates, the ejection mechanism 3 pushes the second end of the push rod 23 to move or rotate, so as to push the first end of the push rod 23 out of the card holder body.

[0028] The electronic device provided by the present application can be a mobile phone, a tablet computer, a notebook computer, a palm computer, a vehicle-mounted electronic device, a Mobile Internet Device (MID), an augmented reality (AR) / virtual reality (VR) device, a robot, a wearable device, an ultra-mobile personal computer (UMPC), a netbook or a personal digital assistant (PDA), etc. The electronic device can also be a personal computer (PC), a television (TV), etc. The embodiment of the present application is not limited specifically. Hereinafter, the electronic device is taken as a mobile phone as an example for introduction.

[0029] The electronic device can further comprise a camera mechanism, a display mechanism, a sound production mechanism and other functional mechanisms, which can be fixed on the supporting mechanism 1 as needed. For example, the display mechanism comprises a flexible display screen body. The supporting mechanism 1 can be used for supporting the flexible display screen body. Part of the flexible display screen body is supported by the first support 11, and another part of the flexible display screen body can be supported by the second support 12 through the rotating assembly 13. The supporting mechanism 1 has a folded state and an unfolded state. The first support 11 and the second support 12 are relatively rotated through the rotating assembly 13 to switch the supporting mechanism 1 between the folded state and the unfolded state. When the first support 11 and the second support 12 are relatively rotated to the folded state, the first support 11 and the second support 12 are stacked. The volume of the electronic device is reduced to facilitate the storage and holding of the supporting mechanism 1. For example, Figure 1 As shown, the first support 11 and the second support 12 are relatively rotated to the unfolded state. The part of the flexible display screen body supported by the first support 11 and the part of the flexible display screen body supported by the second support 12 can be displayed together and flatly, so that the electronic device has a larger display area.

[0030] The rotating assembly 13 can include a hinge, a rotating shaft, a bearing, a traction member, etc. to allow the first support 11 and the second support 12 to rotate relative to each other. During the relative rotation of the first support 11 and the second support 12, part or all of the rotating assembly 13 can move relative to the first support 11.

[0031] The card seat 21 can be arranged on the first support 11 or the second support 12, and the card seat 21 includes a card slot having an entrance 22, and a card holder body (not shown) can be inserted into the card slot from the entrance 22. One or more mounting positions can be arranged on the card holder body, and a data card to be assembled in an electronic device is placed in the mounting position correspondingly, so that the data card can be carried by the card holder body, and the card holder body and the data card are inserted into the card slot together to fix the data card in the electronic device and electrically connect the data card with a control mechanism in the electronic device. The data card can be a subscriber identity module (SIM card), a memory card, etc. The memory card can be an SD (Secure Digital) card, a T-Flash (Trans FLash) card, etc.

[0032] The first end of the push rod 23 extends into the card seat 21 and is used to contact the card holder body, and the second end of the push rod 23 extends out of the card seat 21, so that pushing the part of the push rod 23 extending out of the card seat 21 can drive the part of the push rod 23 extending into the card seat 21 to move or rotate, thereby ejecting the card holder body. The push rod 23 in the present application can refer to the structure for ejecting the card holder body in the related art.

[0033] For example, the ejecting mechanism 3 is arranged on the first support 11, and the push rod 23 used to contact the card holder body can move relative to the card seat 21 between a first position and a second position. When the push rod 23 is located at the first position, the push rod 23 is in contact with or spaced apart from the card holder body, and the push rod 23 does not apply force to the card holder body. When the first support 11 and the second support 12 rotate relative to each other, the rotating assembly 13 drives the transmission member 31 to push the push rod 23 to the second position. When the push rod 23 moves from the first position to the second position, the push rod 23 abuts against the card holder body and applies force to the card holder body, so that the card holder body gradually extends out of the card seat 21. When the push rod 23 is located at the second position, part or all of the card holder body extends out of the card seat 21, so that the user can extract the card holder body. Optionally, the first position and the second position can be arranged relative to each other along the extension direction of the card slot. The push rod 23 moves linearly between the first position and the second position.

[0034] In the embodiments provided in the present application, the ejection mechanism 3 is movably connected with the rotating assembly 13, so that the rotating assembly 13 can drive the transmission member 31 to move or rotate the push rod 23 by rotating, and the push rod 23 can eject the card holder body from the card seat 21. Therefore, without additional configuration of the ejector separated from the electronic device, the card holder body can be extended from the card seat 21, which facilitates the user to take out the card holder body and facilitates the user to replace the data card carried on the card holder body.

[0035] Please refer to Figure 2 When the support mechanism 1 is in the unfolded state, the first support 11 and the second support 12 can be oppositely arranged along the first direction X. The first support 11 has a first side 111 and a second side 112, the first side 111 is connected with the rotating assembly 13, and the second side 112 is oppositely arranged with the first side 111 along the first direction X. The inlet 22 of the card seat 21 can be arranged on the first side 111. The card holder body can also be extended or inserted into the card seat 21 along the first direction X. When the electronic device includes a plurality of card holder mechanisms 2, the plurality of card holder mechanisms 2 can be arranged on the first support 11 and the second support 12, and a plurality of ejection mechanisms 3 can be correspondingly arranged. For example Figure 2 In the embodiment shown in the figure, two card holder mechanisms 2 are arranged on the first support 11 and the second support 12, and two ejection mechanisms 3 are correspondingly arranged to push the push rods 23 of the two card holder mechanisms 2.

[0036] In an embodiment, the ejection mechanism 3 includes a transmission member 31, one end of the transmission member 31 is in transmission connection with the rotating assembly 13, and the other end is used to push the second end of the push rod 23 to move or rotate.

[0037] The transmission member 31 can be a long rod, one end of the transmission member 31 is in transmission connection with the rotating assembly 13, and the other end is used to push the push rod 23, and the transmission member 31 can transmit the power of the rotating assembly 13 to the push rod 23.

[0038] In an embodiment, the transmission member 31 includes a rack portion 311, the rack portion 311 is engaged with the rotating assembly 13, and when the first support 11 and the second support 12 rotate relative to each other, the rotating assembly 13 drives the transmission member 31 to move relative to the card seat 21.

[0039] The rack portion 311 is engaged with the rotating assembly 13, so that the rack portion 311 can translate with the rotating assembly 13, convert the rotating motion of the rotating assembly 13 into linear motion, and realize power transmission between the rotating assembly 13 and the transmission member 31.

[0040] The transmission member 31 can further include a gear, a transmission shaft, or the like, and the gear, the rack portion 311, and the like can be configured to allow the transmission member 31 to be moved relative to the card seat 21 when the rotating assembly 13 drives the transmission member 31 to move, and the other end of the transmission member 31 can drive the second end of the push rod 23 to move or rotate. Alternatively, the rotating assembly 13 and the card holder mechanism 2 are arranged relative to each other along the first direction X, the rack portion 311 extends along the first direction X, and the rack portion 311 includes a plurality of engagement teeth arranged along the first direction X. The engagement teeth arranged along the first direction X allow the rack portion 311 to convert the rotating motion of the rotating assembly 13 into linear motion along the first direction X. The transmission member 31 drives the push rod 23 to move along the first direction X.

[0041] Referring to Figure 1 and Figure 3 In some embodiments, the rotating assembly 13 includes a first rotating shaft 131, a first gear 132, a third support 14, and a fixed gear 136. The first rotating shaft 131 is connected to the first support 11, the first gear 132 is sleeved on the outside of the first rotating shaft 131, the third support 14 is arranged between the first support 11 and the second support 12, the first gear 132 is engaged with the fixed gear 136, and the first gear 132 is engaged with the rack portion 311.

[0042] The third support 14 can further include a fixed shaft 135, and the fixed gear 136 is fixedly sleeved on the outside of the fixed shaft 135. The third support 14 and the fixed gear 136 keep a relative position fixed. With the third support 14 as a reference, the second support 12 rotates relative to the first support 11, the fixed gear 136 keeps a relative position fixed with the third support 14, and the first gear 132 rotates around the fixed gear 136 and drives the rack portion 311 to move linearly along the first direction X.

[0043] The first gear 132 and the fixed gear 136 are engaged to convert the relative rotation between the first support 11 and the second support 12 into linear motion of the rack portion 311.

[0044] In some embodiments, the rotating assembly 13 further includes a second rotating shaft 135 and a second gear 134. The second rotating shaft 135 is connected to the second support 12, and the second gear 134 is sleeved on the outside of the second rotating shaft 135. The first gear 132 and the second gear 134 are engaged with the fixed gear 136, respectively.

[0045] Referring to Figure 4, exemplary, with the first support 11 as a reference, the support mechanism 1 switches from the folded state to the flat state, the second rotating shaft 135 and the second support 12, and the fixed shaft 133 and the third support 14 rotate relative to the first support 11, the second gear 134 rotates in the second rotating direction R2, the first gear 132 rotates in the first rotating direction R1, the first gear 132 drives the transmission member 31 to move linearly in the X direction shown in the figure, so that the push rod 23 can be pulled by the transmission member 31 to move relative to the card holder 21 in the X direction shown in the figure, and the push rod 23 pushes the card holder body out of the card holder 21 in the opposite direction of the X direction shown in the figure. The first rotating direction R1 can be clockwise, and the second rotating direction R2 can be counterclockwise. The second gear 134 can be engaged with the ejection mechanism 3 for ejecting the card holder mechanism 2 arranged on the second support 12.

[0046] In some embodiments, the ejection mechanism 3 includes a transmission member 31, which is in transmission connection with the rotating assembly 13, and the transmission member 31 can be locked or separated from the push rod 23;

[0047] When the transmission member 31 is locked with the push rod 23 and the rotating assembly 13 rotates, the ejection mechanism 3 moves or rotates the second end of the push rod 23, so that the first end of the push rod 23 pushes out the card holder body.

[0048] When the transmission member 31 is locked with the push rod 23, the first support 11 and the second support 12 rotate relative to each other, and the rotating assembly 13 moves the transmission member 31, and the transmission member 31 moves or translates the push rod 23, and the push rod 23 ejects at least part of the card holder body from the card holder 21.

[0049] When the transmission member 31 is separated from the push rod 23, the first support 11 and the second support 12 rotate relative to each other, and the rotating assembly 13 moves the transmission member 31, and since the transmission member 31 is separated from the push rod 23, the push rod 23 remains unchanged relative to the position of the card holder 21 without being affected by the movement of the transmission member 31.

[0050] By setting the transmission member 31 to be locked or separated from the push rod 23, the transmission member 31 can be locked with the push rod 23 as needed, so that the first support 11 and the second support 12 are rotated, and the push rod 23 can push out the card holder body; the transmission member 31 can be separated from the push rod 23, so that the first support 11 and the second support 12 are rotated, and the push rod 23 does not push out the card holder body.

[0051] The user can manually operate the transmission member 31 to be locked or separated from the push rod 23, or a driving assembly 32 can be provided to drive the transmission member 31 to be locked or separated from the push rod 23. In some embodiments, the ejection mechanism 3 further includes a driving assembly 32, which can drive the transmission member 31 to move, so that the transmission member 31 is locked or separated from the push rod 23.

[0052] The driving assembly 32 drives the locking portion 312 of the transmission member 31 to be close to the push rod 23, and the locking portion 312 can be locked with the push rod 23, so that the transmission member 31 can be in power transmission with the push rod 23.

[0053] The driving assembly 32 can be an electromagnetic member, and when the electromagnetic member is powered on, the magnetic field generated by the electromagnetic member attracts the transmission member 31 to move, so as to realize the locking or separation of the transmission member 31 and the push rod 23. The driving assembly 32 can also include a motor, a slide rail and the like. When the card holder body needs to be ejected, the driving assembly 32 drives the transmission member 31 to move in the direction close to the push rod 23, and the transmission member 31 contacts one end of the push rod 23 exposed from the card seat 21. The driving assembly 32 drives the transmission member 31 to further move until the transmission member 31 is locked with the second end of the push rod 23 exposed from the card seat 21. When the card holder body has been taken out or inserted, the driving assembly 32 drives the transmission member 31 to move in the direction away from the push rod 23 until the transmission member 31 is separated from one end of the push rod 23 exposed from the card seat 21.

[0054] In some embodiments, the transmission member 31 includes a rack portion 311 connected in a first direction X and a locking portion 312, the rack portion 311 is in transmission connection with the rotating assembly 13, and the driving assembly 32 can drive the transmission member 31 to move in a second direction Y close to the push rod 23 to lock the transmission member 31 with the push rod 23, and the first direction X and the second direction Y are arranged in intersection.

[0055] The transmission member 31 can be a long rod extending in the first direction X, so that the transmission member 31 has a simple structure. The transmission member 31 and the card holder mechanism 2 can be arranged opposite in the second direction Y, and the driving assembly 32 can drive the transmission member 31 to move in the second direction Y to lock the transmission member 31 with the push rod 23.

[0056] Optionally, the first direction X and the second direction Y are arranged vertically. Those skilled in the art can set the meshing teeth of the rack portion 311 and the surface width of the mutual meshing of the rack portion 311 and the rotating assembly 13 according to the needs, so that when the driving assembly 32 drives the transmission member 31 to move in the second direction Y, the rack portion 311 remains meshing with the rotating assembly 13. Optionally, the rotating assembly 13 includes a first gear 132 meshing with the rack portion 311, and the length of the gear groove of the first gear 132 in the second direction Y is greater than the length of the gear groove of the rack portion 311 in the second direction Y. The length of the gear groove of the first gear 132 in the second direction Y can also be greater than the moving length of the rack portion 311 in the second direction Y, so that when the driving assembly 32 drives the transmission member 31 to move in the second direction Y, the rack portion 311 remains meshing with the rotating assembly 13.

[0057] When the driving assembly 32 is configured to drive the transmission member 31 to move along the second direction Y, and the rotating assembly 13 is configured to drive the transmission member 31 to move along the first direction X, the transmission member 31 can move along with the rotating assembly 13 when the transmission member 31 is locked with or separated from the push rod 23, so as to avoid the transmission member 31 affecting the movement of the rotating assembly 13.

[0058] Please refer to Figure 5 In some embodiments, the locking portion 312 has a locking opening 313, and the driving assembly 32 is configured to drive the transmission member 31 to move towards the push rod 23, so that the push rod 23 is inserted into the locking opening 313.

[0059] The locking opening 313 can be a through hole or a through slot penetrating the locking portion 312 along the second direction Y, or a blind hole formed along the second direction Y. The driving assembly 32 is configured to drive the transmission member 31 to move along the second direction Y towards the push rod 23 until the push rod 23 is inserted into the locking opening 313. The end of the push rod 23 close to the rotating assembly 13 is limited by the wall surface of the locking opening 313, so that when the transmission member 31 moves along the first direction X, the push rod 23 moves along the second direction Y.

[0060] In some embodiments, the driving assembly 32 includes an electroactive elastomer 321, the electroactive elastomer 321 has a first shape and a second shape with different lengths, one end of the electroactive elastomer 321 is connected to the first support 11, and when the voltage applied to the electroactive elastomer 321 reaches a transition voltage, the electroactive elastomer 321 deforms from the first shape to the second shape, and the other end of the electroactive elastomer 321 pushes the transmission member 31 to move towards the push rod 23.

[0061] The electroactive elastomer 321 is a part that can change shape under the action of voltage. For example, when a voltage is applied to the electroactive elastomer 321 to reach a transition voltage, the electroactive elastomer 321 deforms at least along the second direction Y, and the electroactive elastomer 321 pushes the transmission member 31 to move along the second direction Y towards the push rod 23, so that the push rod 23 is locked with the transmission member 31. When the voltage applied to the electroactive elastomer 321 is stopped, the electroactive elastomer 321 at least recovers to the initial shape along the second direction Y, and the electroactive elastomer 321 no longer applies a force along the second direction Y to the transmission member 31.

[0062] Compared with a driving member such as a motor, the electroactive elastomer 321 has a smaller size, which is conducive to the miniaturization of electronic devices.

[0063] In some embodiments, the driving assembly 32 further includes a reset member 322 arranged between the card seat 21 and the transmission member 31, and the reset member 322 is configured to push the transmission member 31 away from the push rod 23.

[0064] The reset member 322 can be a spring, a spring piece, or the like, and can apply a force to the transmission member 31 in a direction away from the push rod 23. When a voltage is applied to the electroactive elastomer 321 to a transition voltage, the electroactive elastomer 321 deforms to a second configuration, and the electroactive elastomer 321 pushes the transmission member 31 to move in a second direction Y to approach the push rod 23, so that the push rod 23 is locked with the transmission member 31. The reset member 322 is compressed between the transmission member 31 and the card seat 21. When the voltage applied to the electroactive elastomer 321 is stopped, the electroactive elastomer 321 returns to the first configuration, and the electroactive elastomer 321 no longer applies a force to the transmission member 31 in the second direction Y. Under the elastic restoring force of the reset member 322, the elastic restoring force pushes the transmission member 31 to move in the second direction Y away from the push rod 23, so that the transmission member 31 is reset.

[0065] Optionally, the reset member 322 is a spring, one end of the spring is fixedly connected with the card seat 21, and the other end of the spring is spaced apart from the transmission member 31.

[0066] In a second aspect, the present application also provides a control method of an electronic device, applied to the electronic device provided in the first aspect, and the control method comprises:

[0067] S100, receiving a first input of a user;

[0068] S200, in response to the first input, controlling the driving assembly to drive the transmission member to move to be locked with the push rod;

[0069] When the first support and the second support are relatively rotated, the rotating assembly drives the transmission member to push the push rod to the second position, and the push rod is pushed out of the card seat to top at least part of the card holder body 。

[0070] The first input can be an input for selecting to pop out the card holder body. The first input can be a pressing input of a certain entity or virtual button in the electronic device by the user, or a specific gesture made by the user and detected by the electronic device. For example, the display mechanism of the electronic device provides an operation interface, and the first input is a clicking operation of a button of “whether to take out the card holder body” displayed on the operation interface by the user. The first input can be determined according to actual use requirements, and the embodiments of the present application do not limit this.

[0071] After the electronic device performs S200, the user can manually push the first support and the second support to be relatively rotated. A driving member for driving the first support and the second support to be relatively rotated can also be arranged in the electronic device, and the first support and the second support are relatively rotated by controlling the driving member.

[0072] Since the scheme needs to rotate the first support and the second support relative to each other, the rotating assembly drives the transmission member to push the push rod to the second position. Therefore, after S200, the display mechanism can be controlled to display prompt information indicating that the locking is completed, so as to prompt the user to rotate the first support and the second support to take out the card holder body.

[0073] Since the support mechanism has the folded state and the unfolded state, the moving direction of the transmission member driven by the rotating assembly when switching from the folded state to the unfolded state is opposite to the moving direction of the transmission member driven by the rotating assembly when switching from the unfolded state to the folded state, so as to ensure that the first support and the second support can be rotated to take out the card holder body after the transmission member is locked with the push rod. Therefore, after S100 and before S200, the display mechanism can be controlled to display prompt information indicating that the first support and the second support are operated to the unfolded state or the folded state. Alternatively, the display mechanism displays prompt information prompting the user to push the first support and the second support to the folded state, and S200 is executed when it is detected that the support mechanism is in the folded state. After the transmission member is locked with the push rod, the display mechanism displays prompt information prompting the user to push the first support and the second support to the unfolded state, so that the user pushes the first support and the second support to the unfolded state, and the rotating assembly drives the transmission member to push the push rod to the second position, and the push rod ejects the card holder body.

[0074] In some embodiments, the driving assembly includes an electroactive elastomer, the electroactive elastomer has a first shape and a second shape with different lengths, and one end of the electroactive elastomer is connected to the first support. S200 includes:

[0075] S210, a voltage is applied to the electroactive elastomer to a transition voltage, the electroactive elastomer is deformed from the first shape to the second shape, and one end of the electroactive elastomer pushes the transmission member to move in a direction close to the push rod.

[0076] After S210, it further includes:

[0077] The voltage applied to the electroactive elastomer is stopped, the electroactive elastomer is deformed from the second shape to a first shape, and the reset member pushes the transmission member to move in a direction away from the push rod.

[0078] By applying a voltage to the electroactive elastomer to a transition voltage, the electroactive elastomer is deformed, and the deformed electroactive elastomer pushes the transmission member to move in a direction close to the push rod to be locked with the push rod, so as to facilitate the miniaturization of the electronic device.

Those skilled in the art can make many forms under the inspiration of the present application without departing from the scope of the present application and the scope protected by the claims.
