[0042] With reference to Figure 4 And Figure 5 The buffer mechanism 9 comprises a first buffer assembly 91, a second buffer assembly 92 and a third buffer assembly 93, the first buffer assembly 91 comprises a first positioning piece 911, a first positioning spring 912, a first positioning rod 913 and a first positioning block 914, the first positioning rod 913 is fixedly connected to the lower shell 4, the shape of the first positioning rod 913 is cylindrical, the first positioning rod 913 is arranged along the X-axis direction, the first positioning block 914 is cuboid, two first positioning blocks 914 are arranged, the two first positioning blocks 914 are arranged in the first positioning rod 913 along the X-axis direction and are slidably connected to the first positioning rod 913, two first positioning springs 912 are arranged, the two first positioning springs 912 are arranged along the Z-axis direction, the two first positioning springs 912 are respectively fixedly connected to the corresponding first positioning blocks 914, the shape of the first positioning piece 911 is hemispherical, two first positioning pieces 911 are arranged, the two first positioning pieces 911 are respectively fixedly connected to the first positioning springs 912 away from the first positioning blocks 914, the bottom of the lower shell 4 is provided with a positioning groove 41, the positioning groove 41 is circular, a plurality of positioning grooves 41 are uniformly arranged along the X-axis direction, the first positioning piece 911 is arranged in the positioning groove 41 along the Z-axis direction and is slidably connected to the positioning groove 41, the positioning groove 41 is used for limiting the first positioning piece 911, when the notebook computer is placed, the lower shell 4 abuts against the reference surface of the external environment, the lower shell 4 is subjected to the external force, thereby driving the first positioning piece 911 to drive the first positioning spring 912 to deform along the Z-axis direction, thereby enabling the first positioning spring 912 to absorb the external force to achieve stress balance, thereby ensuring the stability of the device.

[0043] With reference to Figure 4 And Figure 5 The second buffering assembly 92 comprises a connecting rod 921, a second positioning member 922 and a second positioning spring 923. The second positioning member 922 is cylindrical, is fixedly connected to the lower shell 4, and is arranged along the Z-axis direction. In this embodiment, two second positioning members 922 are arranged symmetrically about the center of the lower shell 4. In this embodiment, the second positioning members 922 are shock absorbers. The arrangement of the second positioning members 922 is conducive to reducing kinetic energy into heat energy consumption through viscous damping, thereby reducing the possibility of impacting the internal computer processor 5 when the lower shell 4 is impacted, and achieving the effects of relieving impact and absorbing vibration.

At the same time, the amplitude of the spring is greater than the amplitude of the shock absorber. The amplitude difference between the two is conducive to ensuring the rapid absorption of vibration. When one side of the notebook computer is impacted, the deformation of the second positioning spring 923 and the second positioning member 922 on one side drives the deformation of the second positioning spring 923 and the second positioning member 922 on the other side through the arrangement of the connecting rod 921, so that the notebook computer quickly ensures that the force is uniform and balanced, thereby being conducive to ensuring the effectiveness and safety of the notebook computer.
