[0039] Specifically, the notebook motherboard 1 structure of this embodiment, when installing the memory module to the mounting seat 3, firstly, the mounting seat 3 is turned over to form the following Figure 3 The mounting base 3 is in a vertically upright state at this time, and the fixing pin 52 is fixed in the fixing groove 21, so that the position of the mounting base 3 is fixed; then the memory stick is inserted into the slot 31 of the mounting base 3 in a vertical insertion manner, which is convenient for installation and can prevent the memory stick from being damaged; after the memory stick is inserted, the memory stick pushes the first piston 41 downward, and after the first piston 41 is pressed downward, the second piston 51 moves, so that the fixing pin 52 withdraws from the fixing groove 21, so that after the memory stick is installed, the mounting base 3 can be turned over again, so that the mounting base 3 and the memory stick are placed horizontally in the placement groove 2 to form a state as shown in the figure. Figure 1 The status shown saves space on the laptop.

[0040] In the notebook motherboard 1 structure described in this embodiment, a first sealed cavity 42 is formed between the bottom of the first piston 41 and the first accommodating groove 4; a first spring 43 is provided in the first sealed cavity 42; a second spring 53 is provided between one end of the second piston 51 and the second accommodating groove 5; a second sealed cavity 54 is formed between the other end of the second piston 51 and the second accommodating groove 5; the fixing pin 52 is provided at the other end of the second piston 51; the first sealed cavity 42 is communicated with the second sealed cavity 54; and a damping liquid is provided between the first sealed cavity 42 and the second sealed cavity 54.

[0041] Specifically, the notebook motherboard 1 structure of this embodiment, when installing the memory module to the mounting seat 3, firstly, the mounting seat 3 is turned over to form the following Figure 3 In the state shown, during the flipping process, under the action of the second spring 53, the fixing pin 52 is in an extended state, and in the process of touching the side wall of the placement slot 2, the fixing pin 52 contracts until the mounting base 3 is flipped to a vertical upright state, and the fixing pin 52 reaches the position of the fixing slot 21. Under the action of the second spring 53, the fixing pin 52 is fixed in the fixing slot 21, thereby fixing the position of the mounting base 3.

[0042] During the process of inserting and installing the memory stick, the memory stick pushes the first piston 41 downward, and during the process of the first piston 41 being pressed downward, the volume of the first sealed cavity 42 gradually decreases, so that the damping fluid in the first sealed cavity 42 flows into the second cavity, so that the volume of the second cavity gradually increases, that is, gradually pushing the second piston 51 to move in the direction of the second spring 53, and at the same time making the fixing pin 52 gradually withdraw from the fixing groove 21; when the memory stick is fully inserted into the slot 31, the fixing pin 52 completely withdraws from the fixing groove 21; at this time, the mounting seat 3 can be flipped again, so that the mounting seat 3 and the memory stick are placed horizontally in the placement groove 2 to form a Figure 1 The status shown can save space in the laptop computer.

[0043] In the notebook motherboard 1 structure described in this embodiment, a clamping block 6 is movably provided on the top of the limit arm 32 along the length direction; a third spring 61 is provided between the end of the clamping block 6 away from the slot 31 and the limit arm 32;

[0045] Specifically, through the above-mentioned arrangement, during the process of installing the memory stick, when the memory stick moves downward, the memory stick pushes the card block 6 to move in the direction of the third spring 61 under the action of the guide slope 63, until the memory card 10 is completely inserted into the slot 31, and the third spring 61 is reset, so that the hook 62 clamps the top of the memory card 10 and can lock the first piston 41 at the same time to prevent the first piston 41 from moving upward.

[0046] In the notebook motherboard 1 structure described in this embodiment, the slot 31 is arranged in the middle of the mounting seat 3; the limiting arms 32 are arranged at both ends of the mounting seat 3;

[0047] A guide groove 33 is formed at one end of the limiting arm 32 close to the slot 31 along the height direction; the first piston 41 is movably disposed at the bottom of the guide groove 33 .

[0048] Specifically, the guide grooves 33 can guide the two ends of the memory stick.

[0049] In the structure of a notebook motherboard 1 described in this embodiment, the limiting arm 32 is provided with a strip groove 34 connected with the guide groove 33; the first piston 41 is provided with an extension arm 7; the extension arm 7 protrudes out of the strip groove 34; both sides of the extension arm 7 are provided with limiting grooves 71; the bottom wall of the placement groove 2 is provided with a receiving groove 73; both sides of the receiving groove 73 are provided with limiting blocks 74 that cooperate with the limiting groove 71; and a fourth spring is provided between the limiting block 74 and the receiving groove 73. Specifically, in the structure of the notebook motherboard 1 described in this embodiment, after the memory stick is completely installed on the mounting seat 3, the mounting seat 3 is flipped so that the extension arm 7 on the mounting seat 3 is inserted into the receiving groove 73 until the limiting groove 71 of the extension arm 7 is clamped with the limiting block 74, and the mounting seat 3 is in a horizontal placement state. Under the action of the limiting groove 71 and the limiting block 74, the stability of the mounting seat 3 and the memory card 10 structure can be maintained.

[0050] In the notebook motherboard 1 structure described in this embodiment, a rotating shaft 22 is provided at the bottom of the mounting seat 3 along the length direction; the rotating shaft 22 is rotatably arranged on one side of the placement slot 2; the fixing slot 21 is arranged on the side wall of one side of the placement slot 2; the above arrangement facilitates the flipping function of the mounting seat 3.

[0051] In the notebook motherboard 1 structure described in this embodiment, a push rod 8 is movably provided on the other side of the placement slot 2; a fifth spring 81 is provided between one end of the push rod 8 and the base 11; the push rod 8 is provided with a connecting block 82; and a connecting slot 64 matching the connecting block 82 is provided on the top of the clamping block 6. In the notebook motherboard 1 structure described in this embodiment, a button 9 is provided for the lifting and lowering of the base 11; a second inclined surface 91 is provided at the bottom of the button 9; and a third inclined surface 83 matching the second inclined surface 91 is provided at the other end of the push rod 8. In the notebook motherboard 1 structure described in this embodiment, both sides of the extension arm 7 are provided with an inclined slot opening 72 connected to the limiting slot 71; and the storage slot 73 is provided with a first inclined surface 76. In the notebook motherboard 1 structure described in this embodiment, the inclined slot opening 72 has the same inclination angle as the first inclined surface 76; and the limiting block 74 is provided at the bottom of the first inclined surface 76.

[0052] Specifically, after the mounting base 3 and the memory card 10 are placed horizontally, when the memory card 10 needs to be taken out, first press the button 9. During the pressing process of the button 9, the push rod 8 moves in the direction of the fifth spring 81 under the cooperation of the second inclined surface 91 and the third inclined surface 83, and the connecting block 82 and the connecting groove 64 make the connecting block 6 move synchronously in the direction of the third spring 61, so that the hook 62 is disengaged from the top of the memory card 10. After the blocking effect of the hook 62 is lost, the first piston 41 gradually moves upward under the resetting effect of the first spring 43, and the extension arm 7 moves synchronously with the first piston 41. Since the inclination angle of the inclined groove opening 72 is the same as the inclination angle of the first inclined surface 76, the mounting base 3 can be flipped along the first inclined surface 76 to Figure 8 and Fig. 9 At this time, the mounting seat 3 is in an inclined position, which makes it easy for the user to remove the memory card 10 from the mounting seat 3.
