[0034] The following will be described in combination with Figure 1 - Figure 13 An electronic device according to embodiments of the present application is described.

[0035] As Figures 1 to 6 indicated, according to some embodiments of the present application, an electronic device is provided, which comprises:

[0036] A device body and a card holder 2, as shown in Figure 3 and Figure 4 , the device body is provided with a slot 1, the slot 1 has an opening 11 and a bottom wall 12 opposite to the opening 11, the bottom wall 12 is provided with a limiting part 13; the slot 1 can also be provided with a card seat so as to cooperate with the card seat after the card holder 2 is inserted into the slot 1.

[0037] As shown in Figure 5 , the card holder 2 is inserted and cooperated with the slot 1 through the opening 11, and the side of the card holder 2 close to the bottom wall 12 is provided with a second elastic member 21; specifically, the side of the card holder 2 close to the bottom wall 12 can be a plane, and one or more second elastic members 21 are arranged on the plane, or the side of the card holder 2 close to the bottom wall 12 can be a curved surface or a bent surface, and one or more second elastic members 21 are arranged on at least one surface of the curved surface or the bent surface.

[0038] The card holder 2 comprises a card insertion state and a card withdrawal state, as shown in Figure 5 and Figure 6 , when the card holder 2 is in the card insertion state, the user can push the card holder 2 to move in the direction of deepening into the slot 1, and the second elastic member 21 cooperates with the limiting part 13, for example, the second elastic member 21 can be clamped with the limiting part 13 after deformation, or the second elastic member 21 can be sleeved on the limiting part 13 with a certain interference amount after deformation, so as to insert and cooperate the card holder 2 in the slot 1 and to the set position, and ensure the cooperation of the card holder 2 and the card seat.

[0039] When the card holder 2 is in the card withdrawal state, first, as shown in Figure 7 and Figure 8In the first stage, the user can push the card tray 2 again to move in the direction of deepening the slot 1, and the card tray 2 and the second elastic member 21 are away from the bottom wall 12 to release the cooperation between the second elastic member 21 and the limiting part 13, that is, to achieve the separation of the second elastic member 21 and the limiting part 13, to achieve the flexible card withdrawal of the card tray 2, avoid the damage of the electronic device caused by the card withdrawal through the ejector pin, and simplify the operation process of the card withdrawal of the electronic device, and improve the card withdrawal experience of the user when using the electronic device.

[0040] Optionally, referring to Figures 3 to 6 , the limiting part 13 comprises a limiting column 131, a limiting head 132 and a sliding block 133, the first end of the limiting column 131 is connected to the bottom wall 12, the second end of the limiting column 131 extends towards the card tray 2, the limiting head 132 is fixed to the second end of the limiting column 131, and the sliding block 133 is slidingly arranged on the limiting column 131, such as being sleeved on the limiting column 131.

[0041] When the card tray 2 is in the card insertion state, the user can push the card tray 2 to move in the direction of deepening the slot 1, and the second elastic member 21 is clamped in the gap between the limiting head 132 and the sliding block 133 after passing the limiting head 132, so that the card tray 2 is inserted into the slot 1 and inserted to a set position, and the cooperation between the card tray 2 and the card seat is ensured.

[0042] When the card tray 2 is in the card withdrawal state, referring to Figure 7 and Figure 8 , the first elastic member 14 can be arranged on the bottom wall 12, the user can push the card tray 2 again to move in the direction of deepening the slot 1, the card tray 2 moves towards the bottom wall 12 and the second elastic member 21 moves to the side of the sliding block 133 close to the bottom wall 12, that is, the second elastic member 21 passes the limiting head 132 and the sliding block 133 and compresses the first elastic member 14 at this time, and the first elastic member 14 is in a compressed state and has elastic potential energy at this time; referring to Figures 9 to 11 , the first elastic member 14 is driven under the reset action of the elastic potential energy, the card tray 2 and the second elastic member 21 are away from the bottom wall 12, and the second elastic member 21 can reversely pass the limiting head 132 and the sliding block 133, so that the second elastic member 21 is separated from the limiting part 13, to achieve the card withdrawal of the card tray 2.

[0043] In addition, the second elastic member 21 and the limiting portion 13 can also be matched as follows: the second elastic member 21 is an elastic tube extending towards the bottom wall 12, and the limiting portion 13 can be a columnar structure extending towards the card holder 2. When the card holder 2 is inserted into the insertion slot 1 and matched with the insertion slot 1, the columnar structure can support the elastic tube to be expanded in the state of being inserted into the elastic tube, and the stable insertion of the card holder 2 into the insertion slot 1 to a certain position is realized by the interference matching between the columnar structure and the elastic tube.

[0044] Optionally, referring to Figure 1 and Figure 2 , an included angle is formed between the second elastic member 21 and the insertion direction of the card holder 2, for example, the second elastic member 21 is arranged along a direction perpendicular to the insertion direction of the card holder 2.

[0045] Specifically, the insertion direction of the card holder 2 can be a horizontal direction in Figure 1 , and the second elastic member 21 can be arranged obliquely to the horizontal direction or along a vertical direction. For example, when the second elastic member 21 is arranged along the vertical direction, in the case that the card holder 2 is in the state of being inserted into the insertion slot 1, the card holder 2 can move in the direction of being inserted into the insertion slot 1 and make the second elastic member 21 abut against the limiting portion 13. The abutting force of the limiting portion 13 on the second elastic member 21 can make the second elastic member 21 retract in the direction away from the limiting portion 13. After the second elastic member 21 passes the limiting portion 13, the second elastic member 21 can be blocked by the limiting portion 13 in the state of being reset, so as to ensure the limiting matching between the second elastic member 21 and the limiting portion 13.

[0046] Optionally, referring to Figure 2 , the second elastic member 21 comprises a movable column 211 and a spring 212. The movable column 211 is telescopically connected to the card holder 2, and the spring 212 is sleeved on the movable column 211 and abuts between the card holder 2 and the end of the movable column 211 away from the card holder 2.

[0047] Specifically, both ends of the movable column 211 can be formed as enlarged ends, and the circumferential dimension of the two enlarged ends is greater than the circumferential dimension of the middle part of the movable column 211. The enlarged end of one end of the movable column 211 can be embedded into the card holder 2 and move in the card holder 2. The spring 212 is sleeved on the movable column 211 and abuts between the card holder 2 and the enlarged end of the other end of the movable column 211, that is, the spring 212 abuts between the card holder 2 and the end of the movable column 211 away from the card holder 2.

[0048] The retraction of the second elastic member 21 in the direction away from the limiting portion 13 under the abutting action can be the retraction of the movable column 211 in the direction away from the limiting portion 13, at which time the enlarged end of the other end of the movable column 211 can compress the spring 212; and after the second elastic member 21 passes the limiting portion 13, the movable column 211 can be reset under the action of the spring 212 recovering the deformation, that is, the movable column 211 can be blocked by the limiting portion 13 to ensure the limiting cooperation between the second elastic member 21 and the limiting portion 13.

[0049] In addition, the second elastic member 21 can also be an elastic deflection head arranged in the insertion direction of the card tray 2, which includes a spring sheet and a deflection head. One end of the spring sheet is connected to the card tray 2, and the other end of the spring sheet is connected with the deflection head. When the card tray 2 is inserted into the insertion slot 1, the limiting portion 13 abuts against the deflection head and deforms the spring sheet, so that the deflection head is blocked by the limiting portion 13 after passing the limiting portion 13.

[0050] Optionally, referring to Figure 1 and Figure 2 , the electronic device includes two second elastic members 21, and the two second elastic members 21 are oppositely arranged on the card tray 2.

[0051] Specifically, when the two second elastic members 21 are oppositely arranged, a gap can be formed between the two second elastic members 21. When the card tray 2 is inserted into the insertion slot 1, the limiting portion 13 can extend into the gap formed between the two second elastic members 21 and push the two second elastic members 21 to retract simultaneously. After the two second elastic members 21 pass the limiting portion 13, the two second elastic members 21 can be blocked by the limiting portion 13 in the reset state, thereby ensuring the stability of the insertion cooperation between the card tray 2 and the insertion slot 1.

[0052] Optionally, referring to Figure 1 , the card tray 2 is provided with a groove 22 on the side close to the bottom wall 12, and the two second elastic members 21 are arranged on the opposite two side walls of the groove 22, respectively.

When the card holder 2 is inserted into the slot 1, the two second elastic members 21 arranged in the groove 22 can avoid occupying the space between the card holder 2 and the bottom wall 12, so that the cooperation between the second elastic member 21 and the limiting portion 13 is also located in the groove 22, which can avoid excessive occupation of the internal space of the electronic device by the groove 22 on the basis of ensuring that the card holder 2 is inserted into the slot 1 in place.

[0054] Optionally, referring to Figures 5 to 11 , the end of the movable column 211 away from the card holder 2 has a first side wall facing the limiting head 132, and the limiting head 132 has a second side wall facing the movable column 211;

[0055] When the card holder 2 is in the card insertion state, the movable column 211 is close to the limiting head 132, the first side wall abuts against the second side wall and makes the movable column 211 move in the direction of extending into the card holder 2.

[0056] Specifically, when the card holder 2 is in the card insertion state, in order to facilitate the second elastic member 21 to pass through the limiting head 132 and be clamped between the limiting head 132 and the sliding block 133, the movable column 211 can be applied with a force in the direction of the card holder 2 through the abutting cooperation between the first side wall and the second side wall, so that the movable column 211 is retracted in the direction of extending into the card holder 2, and in the process of retracting the movable column 211, the movable column 211 can smoothly pass through the limiting head 132 and be clamped between the limiting head 132 and the sliding block 133 under the action of the spring 212.

[0057] Optionally, the surface of the first side wall is a bevel or an arc surface, and the surface of the second side wall is a bevel or an arc surface.

[0058] Specifically, referring to Figure 5 and Figure 6, the surface of the first side wall and the surface of the second side wall can be inclined surfaces, and when the movable column 211 approaches the limiting head 132, the first side wall can first abut against the second side wall, and when the movable column 211 continues to move towards the limiting head 132, the second side wall can apply a force to the movable column 211 in the direction of the card holder 2 through the first side wall, so as to realize the retraction of the movable column 211 in the direction of the card holder 2.

[0059] In addition, the surface of the first side wall and the surface of the second side wall can also be arc surfaces, or one of the surface of the first side wall and the surface of the second side wall is an inclined surface, and the other is an arc surface, and both can realize the purpose that the second side wall can apply a force to the movable column 211 in the direction of the card holder 2 through the first side wall.

[0060] Optionally, referring to Figure 9 and Figure 10 , one side of the sliding block 133 close to the bottom wall 12 is provided with a third side wall;

[0061] When the card holder 2 is in the card withdrawal state, the card holder 2 moves towards the bottom wall 12 and makes the second elastic member 21 move to the side of the sliding block 133 close to the bottom wall 12, the third side wall cooperates with the end of the movable column 211 away from the card holder 2, so as to separate the movable column 211 from the sliding block 133 and the limiting portion 13.

[0062] Specifically, the surface of the third side wall can be an inclined surface or an arc surface towards the bottom wall 12, when the second elastic member 21 moves to the side of the sliding block 133 close to the bottom wall 12, the first elastic member 14 is in a compressed state and has elastic potential energy; the first elastic member 14 drives the card holder 2 and the second elastic member 21 away from the bottom wall 12 under the reset action of the elastic potential energy, and in order to facilitate the movable column 211 to reversely pass through the limiting head 132 and the sliding block 133, the movable column 211 can be made to move away from the bottom wall 12 along the third side wall, so as to smoothly realize the separation of the movable column 211 from the sliding block 133 and the limiting portion 13.

[0063] In addition, the electronic device can include two first elastic members 14, and the two first elastic members 14 can be spaced apart and abut against the side of the card holder 2 close to the bottom wall 12, so as to ensure the stability of the card holder 2 when withdrawing from the slot 1.

[0064] Optionally, referring to Figure 9 and Figure 10 , in the direction of the opening 11 towards the bottom wall 12, the circumference of the second side wall gradually increases, and the circumference of the second side wall gradually decreases.

[0065] Referring to Figure 10 , the direction of the opening 11 towards the bottom wall 12 can be a right direction, and the gradually increasing circumference of the second side wall can be a right-upward inclination of the second side wall, so that the movable column 211 can smoothly pass the limiting head 132 during the retraction of the movable column 211, and the movable column 211 is clamped between the limiting head 132 and the slider 133 under the action of the spring 212.

[0066] And the gradually decreasing circumference of the second side wall, that is, the left-upward inclination of the second side wall, can make the movable column 211 pass the limiting head 132 and the slider 133 in reverse, so that the movable column 211 is away from the bottom wall 12 along the third side wall, to smoothly realize the separation of the movable column 211 from the slider 133 and the limiting portion 13.

[0067] Optionally, referring to Figure 12 and Figure 13 , the maximum circumferential dimension of the slider 133 is greater than the maximum circumferential dimension of the limiting head 132.

[0068] Specifically, the circumferential shape of the slider 133 and the limiting head 132 can both be circular, and the diameter of the slider 133 can be greater than the diameter of the limiting head 132. When the second elastic member 21 passes the limiting head 132 and the slider 133 in reverse to separate the second elastic member 21 from the limiting portion 13, the slider 133 will be close to the limiting head 132 or even fit with the limiting head 132. When the slider 133 and the limiting head 132 fit together, it will hinder the second elastic member 21 from being clamped between the limiting head 132 and the slider 133. When the maximum circumferential dimension of the slider 133 is greater than the maximum circumferential dimension of the limiting head 132, the second elastic member 21 can abut to the position of the slider 133 protruding from the limiting head 132 when the card holder 2 is inserted into the insertion slot 1, thereby driving the slider 133 and the limiting head 132 to separate, so as to facilitate the insertion and mating cooperation of the card holder 2 and the insertion slot 1 again.

[0069] The electronic device includes but is not limited to one of a smart watch, a mobile phone, a tablet computer, an e-book reader, an MP3 player, an MP4 player, a computer, a set-top box, a smart television, and a wearable device.

[0070] Optionally, referring to Figures 1 to 4, the first elastic member 14 is compressed, and the first elastic member 14 drives the card holder 2 and the second elastic member 21 away from the bottom wall 12 under the restoring action of the elastic potential energy, so as to release the cooperation between the second elastic member 21 and the limiting portion 13.

[0071] Specifically, when the card holder 2 is in the card withdrawing state, first, referring to a first stage of Figure 7 and Figure 8 , the user can push the card holder 2 again to move in the direction of deepening into the slot 1, so that the card holder 2 moves towards the bottom wall 12 and compresses the first elastic member 14, at this time, the first elastic member 14 is in a compressed state and has elastic potential energy; second, referring to a second stage of Figures 9 to 11 , the first elastic member 14 automatically drives the card holder 2 and the second elastic member 21 away from the bottom wall 12 under the restoring action of the elastic potential energy, so as to release the cooperation between the second elastic member 21 and the limiting portion 13, that is, to achieve the separation of the second elastic member 21 and the limiting portion 13, to achieve the purpose of automatically withdrawing the card holder 2, avoiding the damage to the electronic device caused by withdrawing the card through the ejector pin, and simplifying the operation process of withdrawing the card of the electronic device, and improving the card withdrawing experience of the user when using the electronic device.
