[0038] Among them, various computer accessories are installed inside the main box body 1 to form a chassis structure. When the chassis is started, the cooling fan 112 is started synchronously to dissipate heat for the accessories. The fresh air from the outside is filtered and dusted by the filter plate 114 to form a clean airflow. The clean air flows into the main box body 1 through the air inlet slot 111, and heat is exchanged with the various accessories inside the main box body 1. The airflow carrying waste heat is discharged through the air outlet side plate 12 and the top plate 4, completing the air cooling and heat dissipation cycle.

[0039] The opening and closing method of the first air outlet slot 121 on the air outlet side plate 12 is:

[0040] The first stepper motor 125 drives the first paddle 126 to rotate a certain angle, and the first baffle 123 slides along the first slide groove 122 under the drive of the first paddle 126, and the first spring 124 is compressed synchronously.

At this time, the state of the top plate 4 is as follows: Figure 8 As shown, the multiple groups of second air outlet slots 41 on the top plate 4 are in an open state, and normal ventilation and heat dissipation can be achieved through the second air outlet slots 41;

[0044] When the chassis is closed and the cooling fan 112 is not working, the second stepper motor 45 drives the second paddle 46 to rotate a certain angle, and the second baffle 43 slides along the second slide groove 42 under the action of the rebound force of the second spring 44. The second baffle 43 moves horizontally to one side for a distance, and the multiple groups of second air outlet slots 41 on the top plate 4 are blocked by the second baffle 43. At this time, the multiple groups of second air outlet slots 41 are in a closed state. When the chassis is not in use, the chassis as a whole is in a closed state.

[0045] In some examples, the first paddle 126 and the second paddle 46 are both configured as cam structures.

[0046] Among them, the first stepper motor 125 can drive the first paddle 126 to rotate a certain angle, and the second stepper motor 45 can drive the second paddle 46 to rotate a certain angle. The stepper motor drives the cam structure to rotate, and then drives the baffle corresponding to the cam structure to move, thereby automatically controlling the opening and closing of the air outlet.

[0047] In some examples, the first paddle 126 is in contact with the first baffle 123 , and the second paddle 46 is in contact with the second baffle 43 .

[0048] When the first stepper motor 125 is working, it drives the first paddle 126 to rotate, and drives the first baffle 123 to slide along the first slide groove 122 through the first paddle 126 and the first spring 124. When the second stepper motor 45 is working, it drives the second paddle 46 to rotate, and drives the second baffle 43 to slide along the second slide groove 42 through the second paddle 46 and the second spring 44.

[0049] In some examples, three groups of air inlet slots 111 are provided, three groups of cooling fans 112 are provided, and the cooling fans 112 are fixedly connected to the air inlet side panels 11 by screws. The connection method is simple, and the installation and disassembly of the cooling fans 112 are convenient. The three groups of cooling fans 112 dissipate heat simultaneously, thereby improving the cooling efficiency of the chassis.

[0050] In some examples, a plurality of mounting slots 131 are provided on the mounting back plate 13, and the mounting back plate 13 is fixedly connected to the main box body 1 by screws. The mounting back plate 13 provides mounting positions for various computer accessories, and the plurality of mounting slots 131 are used for installing accessories and routing wires.

[0052] In some examples, the filter plate 114 includes a filter layer, and the filter plate 114 is elastically connected to the air inlet side plate 11 via a second elastic connecting strip 113. The second elastic connecting strip 113 forms a side buffer area. When an external force acts on the side of the main box body 1, the elastic deformation ability of the second elastic connecting strip 113 can absorb part of the energy, reduce the impact force acting on the main box body 1, and thereby reduce the impact force acting on the computer accessories inside the main box body 1.

[0053] Before the outside fresh air enters the chassis, it first passes through the filter plate 114, and the fresh air is filtered by the filter layer of the filter plate 114 to remove dust particles in the outside fresh air, so that the fresh air forms a clean airflow, and the clean airflow then enters the chassis through the air inlet slot 111.

[0054] In some examples, panel 14 includes multiple sets of interfaces.

[0055] The panel 14 is an area on the computer case for connecting various input and output devices, including various interfaces and necessary physical structures to facilitate users to connect and manage hardware devices.

[0056] By adopting the above technical solution:

[0057] The heat dissipation method of the chassis is that the air enters on one side and exits on the other side and the top. Before the fresh air enters the chassis, it is first filtered and dust-removed by the filter plate 114 to form a clean airflow to prevent external dust from entering the chassis. The first air outlet slot 121 and the second air outlet slot 41 are automatically opened for heat dissipation during heat dissipation. The air outlet slot is in a positive pressure state to prevent external dust from entering. The first air outlet slot 121 and the second air outlet slot 41 are automatically closed when the chassis is closed, so that the entire chassis is in a closed state, thereby preventing external dust particles from entering the chassis through the slot structure, improving the dustproof effect of the chassis, and avoiding dust accumulation on the internal accessories of the chassis.

[0058] The filter plate 114 on one side of the chassis is elastically connected to the main box body 1, and the top plate 4 on the top of the chassis is elastically connected to the main box body 1. When external force acts on the filter plate 114 or the top plate 4, part of the impact force is absorbed by the first elastic connecting strip 15 and the second elastic connecting strip 113, thereby reducing the impact force acting on the main box body 1, and then reducing the impact force acting on the internal accessories of the chassis, thereby improving the protection effect of the chassis.

[0059] Embodiment 2:

[0060] Based on Example 1, this example introduces a specific structure of a main case 1, a front baffle 2 and a rear baffle 3 in a computer case protection device. Magnetic card slots 6 are provided at the corners of the front end face and the rear end face of the main case 1, and magnetic protrusions 5 are provided at the corners of the inner sides of the front baffle 2 and the rear baffle 3.

[0061] In some examples, multiple groups of magnetic protrusions 5 correspond one-to-one to multiple groups of magnetic card slots 6, and the magnetic card slots 6 and the magnetic protrusions 5 are magnetically fixed, the main box body 1 and the front baffle 2 are magnetically fixed, and the main box body 1 and the rear baffle 3 are magnetically fixed.

[0062] Among them, when installing the front baffle 2, the multiple groups of magnetic protrusions 5 of the front baffle 2 are embedded in the multiple groups of magnetic slots 6 of the main case 1, so as to realize the magnetic fixation between the front baffle 2 and the main case 1. When installing the rear baffle 3, the multiple groups of magnetic protrusions 5 of the rear baffle 3 are embedded in the multiple groups of magnetic slots 6 of the main case 1, so as to realize the magnetic fixation between the rear baffle 3 and the main case 1. When removing the front baffle 2, it is only necessary to apply a certain external force to the front baffle 2 to overcome the magnetic attraction force, so that the front baffle 2 can be removed alone. When removing the rear baffle 3, it is only necessary to apply a certain external force to the rear baffle 3 to overcome the magnetic attraction force, so that the rear baffle 3 can be removed alone, which is convenient for the installation and disassembly of computer accessories.

[0063] The front baffle 2 and the rear baffle 3 can both be made of transparent material to increase the aesthetics of the chassis.

[0064] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
