DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Example 1, with reference to Figure 1-5 A computer structure that is easy to disassemble for computer teaching, comprising a base 1 with universal wheels with brakes installed at the four corners of the bottom and an angle adjustment base 2 hinged to the middle of the top of the base 1;

[0036] In this embodiment, the base 1 is provided with a tilt angle adjustment mechanism, and the angle adjustment seat 2 is connected to a computer host 3 via a height adjustment mechanism. The components in the computer host 3 belong to existing mature technologies and are not shown in detail in the figure in this embodiment.

[0037] Specifically, a sliding cover structure is provided on one side of the computer host 3, and the sliding cover structure includes a lighting assembly, an electric slide rail 5 fixedly mounted on the top outer wall of the computer host 3, and a side cover 4 fixedly connected to the slider portion 6 of the electric slide rail 5;

[0038] Furthermore, the lighting assembly includes a positive electrode power supply sheet 7 fixedly connected to the inner wall of the side cover 4, a negative electrode power supply sheet 8 fixedly connected to the inner wall of the other side of the computer host 3, and a lighting lamp 9 fixedly installed on the inner wall of the top of the computer host 3;

[0039] Furthermore, the side cover 4 is adapted to and slidably connected to the computer host 3. Two slide bars are symmetrically fixed to the inner side wall of the side cover 4, and two slide rails adapted thereto are symmetrically opened on one side of the computer host 3.

[0040] When the sliding cover structure is in use, the side cover 4 is automatically opened and closed by the slider portion 6 of the electric slide rail 5, which gets rid of the traditional bolt connection method, making the disassembly and assembly of the side cover 4 of the computer host 3 convenient and quick, avoiding the situation where the disassembly and assembly of the side cover 4 takes up too much teaching time and affects the teaching efficiency. After the side cover 4 is fully opened, the positive power-carrying piece 7 inside it will overlap the negative power-carrying piece 8 to realize the automatic turning on of the lighting lamp 9. Conversely, after the side cover 4 is closed, the positive power-carrying piece 7 will separate from the negative power-carrying piece 8 to realize the automatic power-off effect of the lighting lamp 9. In this way, after the side cover 4 is opened, it can ensure that there is sufficient light vision inside the computer host 3, which is convenient for teaching staff to better explain the details of the parts inside the computer host 3, and helps to improve the quality and efficiency of computer teaching.

[0041] Specifically, the tilt angle adjustment mechanism includes an electric control component, a slide groove opened on the top of the base 1, a transverse screw 10 rotatably installed in the slide groove, a sliding block 11 threadedly connected to the front end of the transverse screw 10, and an adjustment arm 12 hinged between the sliding block 11 and the angle adjustment base 2;

[0042] Furthermore, the outer wall of the sliding block 11 is slidably connected to the inner wall of the chute, and two hydraulic telescopic guide rods 13 are symmetrically hinged between the top of the base 1 and one side of the angle adjustment seat 2.

[0043] Furthermore, the electric control assembly includes a fixed cover 14 fixedly mounted on the side wall of the base 1, a first stepper motor 15 fixedly mounted on the side wall of the fixed cover 14, a driving pulley 16 fixedly mounted on the output shaft of the first stepper motor 15, and a driven pulley 17 fixedly mounted on one end of the transverse screw 10. The output shaft of the first stepper motor 15 extends into the fixed cover 14, and the driving pulley 16 and the driven pulley 17 are connected by the same transmission belt 18.

[0044] When the above-mentioned inclination angle adjustment mechanism is in use: the first stepper motor 15 drives the active pulley 16 to rotate, and then under the transmission effect of the transmission belt 18, the driven pulley 17 will drive the transverse screw 10 to rotate, and then under the limit of the slide groove, the sliding block 11 threadedly connected to the transverse screw 10 will move backward, thereby causing the adjustment arm 12 to gradually pull the angle adjustment seat 2 backward to change its inclination angle. This makes it easy to flexibly adjust the inclination angle of the computer host 3, so as to meet the teaching display needs of the computer host 3 at different angles, and further improve the quality and efficiency of computer teaching.

[0046] Furthermore, slide rails are provided on both sides of the angle adjustment base 2, the host connection base 21 is slidably connected between the two slide rails, and the computer host 3 is fixedly connected to the side wall of the host connection base 21 by bolts;

[0047] Furthermore, the electric drive assembly includes a protective shell 22 fixedly connected to the top outer wall of the angle adjustment base 2, a second stepper motor 23 fixedly mounted on the side wall of the protective shell 22, a worm 24 fixedly mounted on the output shaft of the second stepper motor 23, and a worm wheel 25 fixedly mounted on the top of the vertical screw 19 and meshing with the worm 24. The output shaft of the second stepper motor 23 extends into the protective shell 22.

[0048] When this embodiment is used in practice: the worm 24 is controlled to rotate by the second stepper motor 23, and then the worm wheel 25 engaged with the worm 24 drives the vertical screw 19 to rotate, and then the lifting member 20 threadedly connected to the vertical screw 19 drives the host connecting seat 21 to slide upward between the two slide rails, so that the placement height of the computer host 3 can be flexibly adjusted to better meet the usage requirements in different teaching situations.

[0049] Example 3, reference Figure 1-2 、 Figure 5 and Figure 8 This embodiment is optimized based on the embodiment 1. Specifically, a heat dissipation mechanism is provided on the computer host 3. The heat dissipation mechanism includes a heat dissipation fan 26 and a heat dissipation window 36 fixedly mounted on the other side of the computer host 3 in sequence, and a kinetic energy utilization component provided outside the computer host 3.

[0051] Furthermore, a guide opening adapted for the push column 30 is provided on the reciprocating swing frame 29, and teeth 34 meshing with the sector gear 31 and distributed at equal distances are welded on the outer wall of the guide shaft 33, and a bristle structure contacting the heat dissipation window 36 is provided on the brush plate 35;

[0052] In specific use of this embodiment: when the computer host 3 is in daily use, the ventilation cooperation of the cooling fan 26 and the cooling window 36 can quickly discharge the internal heat to the outside to achieve the effect of rapid heat dissipation, and the cooling fan 26 will drive the rotating wheel 27 to rotate when working, and then the pushing column 30 on the rotating wheel 27 will make a reciprocating motion to drive the reciprocating swing frame 29 to swing back and forth, and then the reciprocating swing of the fan-shaped gear 31 at the bottom of the reciprocating swing frame 29 will drive the guide shaft 33 with multiple teeth 34 to reciprocate back and forth, so that the brush plate 35 at one end of the guide shaft 33 will reciprocate on the surface of the cooling window 36 to effectively clean the dust and impurities attached to its surface, which helps to improve the ventilation and heat dissipation efficiency. In this way, the kinetic energy of the cooling fan 26 during operation can be converted into the reciprocating motion of the brush plate 35, and the kinetic energy in the heat dissipation process can be reasonably utilized.
