The card support plugging mechanism provided by the embodiment of the invention is used for realizing the taking and the placing of the SIM card, and the card support plugging mechanism is arranged on a mainboard of the electronic equipment. In the prior art, a thimble insertion hole is usually formed in a card support plug mechanism or a frame on one side of the card support plug mechanism, and a popup part of the card support plug mechanism is triggered by inserting a thimble into the thimble insertion hole, so that the card support 11 pops out. However, since the thimble insertion hole is formed in the card support 11 or the frame on one side of the card support 11, on one hand, the consistency of the surface of the electronic device is damaged, and on the other hand, the waterproof difficulty of the electronic device is increased. Based on this, the embodiment of the invention provides the card support plugging mechanism which does not provide a thimble insertion hole on the card support plugging mechanism or a frame on one side of the card support plugging mechanism so as to improve the waterproof performance of the electronic equipment.
The card holder assembly 1 of the card holder plugging mechanism comprises a card holder 11, a card holder 12 and a first elastic element 13, wherein the card holder 12 is fixed on the mainboard, and the card holder 11 is plugged on the card holder 12, so that the card holder 11 can be pulled out of the card holder 12 to realize the taking and placing of the SIM card. One end of the first elastic element 13 is fixed on the clamping seat 12, the first elastic element 13 may be a spring, and an elastic coefficient of the first elastic element 13 is determined according to a resilient force required by the lever assembly 2, which is not limited in the embodiment of the present invention. A limiting part 14 is arranged on one side edge of the card support 11, the limiting part 14 can be a limiting protrusion or a limiting groove, and the specific shape is determined according to the processing technology of the card support 11. Thus, the card holder 11 can be limited by the limiting part 14, so that the first elastic element 13 is compressed, and power is provided for ejecting the card holder 11.
The lever assembly 2 includes a transmission lever 21 and a second elastic element 22, and the transmission lever 21 may be a metal material with certain elasticity, such as an aluminum alloy, so that the transmission lever 21 has certain buffering when the position of the transmission lever 21 changes. The transmission lever 21 is hinged with the main board, and the hinged point is a fulcrum of the transmission lever 21. In a possible implementation manner, a through hole may be formed in the middle of the transmission rod, a rotation shaft is fixed on the main board, the transmission lever 21 is hinged to the main board through the rotation shaft, and the hinge point is a fulcrum of the transmission lever 21, so that after one end of the transmission lever 21 is pressed downwards, the other end of the transmission lever 21 is tilted upwards. The second elastic element 22 may also be a spring, and one end of the second elastic element 22 is fixedly connected to the main board, for example, a fixing rod may be fixedly connected to the main board, and one end of the second elastic element 22 is fixedly connected to the main board through the fixing rod. The other end of the second elastic element 22 is fixedly connected with the end of the transmission lever 21. In the embodiment of the present invention, an end of the second elastic member 22 connected to the main board is defined as a first end of the second elastic member 22, and an end of the second elastic member 22 connected to the actuating lever 21 is defined as a second end of the second elastic member 22. It should be noted that the second end of the second elastic element 22 may be connected to either end of the actuating lever 21, when the second end of the second elastic element 22 is connected to the end of the actuating lever 21 pressed downward, the second elastic element 22 is in an extended state when the end of the actuating lever 21 is pressed downward, and when the second end of the second elastic element 22 is connected to the end of the actuating lever 21 lifted upward, the second elastic element 22 is in an extended state when the end of the actuating lever 21 is lifted upward. Thus, when the end of the transmission lever 21 is applied with force, the position of the rotation lever is changed, and the second elastic member 22 is in an extended state, and when the end of the transmission lever 21 is removed, the transmission lever 21 can be restored to the original position by the elastic force of the second elastic member 22.
The bottom of the socket 3 is provided with a through hole, and the size of the through hole is determined according to the diameter of the contact pin 4, so that the through hole can provide a channel for the contact pin 4 to be in abutting contact with the first end of the transmission lever 21. Thus, the first end of the actuating lever 21 can be subjected to a pressing-down force by the pin 4. When the first elastic element 13 is in a compressed state, the second end of the first elastic element 13 contacts the retainer 11, and the second end of the transmission lever 21 contacts the limiting portion 14 in a pressing manner. Specifically, when the card holder 11 is inserted into the card holder 12, the second end of the transmission lever 21 may abut against the limiting portion 14 of the card holder 11, so that the first elastic element 13 is in a compressed state under the abutting of the card holder 11, and the card holder 11 is fixed in the card holder 12. When the card support 11 needs to be taken out, the pin 4 can be used for abutting against the first end of the transmission lever 21 through the through hole formed in the bottom of the socket 3, so that the first end of the transmission lever 21 is pressed downwards, the second end of the transmission lever 21 is tilted upwards, and meanwhile, the second elastic element 22 is driven to extend, so that the second end of the transmission lever 21 is separated from the limiting part 14, the first elastic element 13 loses the abutting force of the card support 11 and recovers the original length, and then the card support 11 is ejected out of the card seat 12 under the elastic force of the first elastic element 13, and the card support 11 is taken out. When the card holder 11 is ejected, the pin 4 can be pulled out, so that the actuating lever 21 is restored to its original state by the resilient force of the second resilient member 22. It should be noted that, when the inserting pin 4 presses against the first end of the transmission lever 21, so that the first end of the transmission lever 21 is pressed downward, and the second end of the transmission lever 21 is tilted upward, the second end of the transmission lever 21 may interfere with the limiting portion 14, and since one end of the card holder 11 contacts with the first elastic element 13, the card holder 11 can continue to move toward the direction in which the second elastic element 22 is compressed, so that the interference between the second end of the transmission lever 21 and the limiting portion 14 disappears, and finally the second end of the transmission lever 21 is tilted upward, so that the second end of the transmission lever 21 is separated from the limiting portion 14.
As can be seen from the above technical solutions, in the embodiment of the present invention, when the card holder 11 is inserted into the card holder 12, the second end of the transmission lever 21 can be pressed against the limiting portion 14 of the card holder 11, so that the first elastic element 13 is in a compressed state under the pressing of the card holder 11, and the card holder 11 is fixed in the card holder 12. When the card support 11 needs to be taken out, the pin 4 can be used for abutting against the first end of the transmission lever 21 through the through hole formed in the bottom of the socket 3, so that the first end of the transmission lever 21 is pressed downwards, the second end of the transmission lever 21 is tilted upwards, and meanwhile, the second elastic element 22 is driven to extend, so that the second end of the transmission lever 21 is separated from the limiting part 14, the first elastic element 13 loses the abutting force of the card support 11 and recovers the original length, and then the card support 11 is ejected out of the card seat 12 under the elastic force of the first elastic element 13, and the card support 11 is taken out. When the card holder 11 is ejected, the pin 4 can be pulled out, so that the actuating lever 21 is restored to its original state by the resilient force of the second resilient member 22. Therefore, the contact pin 4 can be controlled to the clamping seat component 1 by virtue of the through hole formed in the bottom of the clamping seat 12, the clamping support 11 can be taken out, the through hole can be prevented from being formed in one side of the clamping seat component 1 or the clamping seat component 1, the consistency of the surface of the electronic equipment cannot be damaged, and the waterproof difficulty of the electronic equipment is reduced.
