Description

Technical Field

[0001] The utility model relates to the technical field of chassis protection, in particular to a computer chassis protection structure. Background Art

[0002] The heat dissipation design of computer chassis often follows the natural convection principle of bottom air intake and top air exhaust or front air intake and rear air exhaust to optimize the heat dissipation efficiency. However, in the actual use environment, dust is easily accumulated on the ground, and this design makes dust easily enter the internal space of the chassis through the bottom of the chassis.

[0003] Although a dust filter is equipped at the bottom of the chassis to block most of the particulate matter, unfortunately, fine dust can still penetrate through the gaps of the filter and penetrate into the chassis. After long-term accumulation, it may adhere to key components such as circuit boards, fans, and heat sinks, not only affecting the heat dissipation performance, but also possibly causing short circuits, accelerating hardware aging, and even leading to system failures, affecting the stable operation and service life of the computer. Therefore, a new solution is needed to solve the above problems. Summary of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a computer chassis protection structure to solve the technical problem that dust easily enters the chassis from the ground.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A computer chassis protection structure includes a "concave"-shaped protection frame at the bottom of the chassis and several heightening blocks on the inner bottom wall of the protection frame. The chassis is mounted on the heightening blocks, and there is a spacing between the side wall of the chassis and the inner wall of the protection frame.

[0007] By adopting the above technical solution, the air duct at the bottom of the chassis is changed by the protection frame. The air that originally entered from the ground upward now enters from the top opening of the protection frame, which can effectively prevent the dust on the floor from being directly sucked into the chassis. In addition, the heightening blocks can ensure the smoothness of the air intake channel.

[0008] The utility model is further configured such that the inner top surface of the protection frame is composed of two connected inclined surfaces, and the ends of the two inclined surfaces close to each other are higher.

[0009] By adopting the above technical solution, the dust falling on the protection frame will accumulate on both sides, thus keeping away from the air intake at the bottom of the chassis and reducing the dust entering the chassis.

[0010] The utility model is further configured such that a filter screen is provided inward at the opening edge of the protection frame.

[0011] By adopting the above technical solution, the filter screen can reduce the floating dust from falling into the protection frame, and further reduce the dust entering the chassis.

[0012] The utility model is further configured such that the filter screen is hinged to the opening edge of the protective frame.

[0013] By adopting the above technical solution, for chassis of different sizes, the movable end of the filter screen can be lapped on the side wall of the chassis, so as to achieve the filtering effect and ensure the applicability of the protection structure to chassis of different sizes.

[0014] The utility model is further configured such that the filter screen is transparent.

[0015] By adopting the above technical solution, the transparent filter screen is adapted to most current transparent chassis, ensuring the visual effect of the transparent chassis.

[0016] The utility model is further configured such that a spare air duct is provided through the bottom surface of the protective frame, and a closing member is movably provided on the spare air duct.

[0017] By adopting the above technical solution, for the situation where the floor at home is relatively clean, this protective frame still provides a method of air intake from the bottom. Only by removing the closing member can the bottom air intake be realized, thereby improving the applicability.

[0018] The utility model is further configured such that the cross section of the closing member is in the shape of "π".

[0019] By adopting the above technical solution, the closing member of this shape can not only be directly stuck in the spare air duct to achieve the closing effect, but also be convenient to take and place.

[0020] The utility model is further configured such that pulleys are provided at the bottom of the protective frame.

[0021] By adopting the above technical solution, the pulleys facilitate the movement of the chassis on the ground.

[0022] In summary, the utility model mainly has the following beneficial effects:

[0023] 1. By providing a protective frame, the air duct at the bottom of the chassis is changed by the protective frame. The air that originally entered from the ground upward now enters from the top opening of the protective frame, which can effectively prevent the dust on the floor from being directly sucked into the chassis. In addition, the heightening blocks can ensure the smoothness of the air intake channel;

[0024] 2. By providing a filter screen on the protective frame, the floating dust falling into the protective frame can be reduced, and further the dust entering the chassis can be reduced;

[0025] 3. By providing a spare air duct and a closing member, for the situation where the floor at home is relatively clean, this protective frame still provides a method of air intake from the bottom. Only by removing the closing member can the bottom air intake be realized, thereby improving the applicability. Description of the Drawings

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0030] The following describes an embodiment of the utility model based on its overall structure.

[0031] A computer case protection structure, as shown in the figure, includes a "concave"-shaped protection frame 2 located at the bottom of the case 1 and a plurality of padding blocks 3 located at the inner bottom wall of the protection frame 2. The case 1 is mounted on the padding blocks 3, and the padding blocks 3 are preferably provided with a clearance groove (not shown in the figure) for the legs of the case 1 to be inserted. A pulley 7 is provided at the bottom of the protection frame 2, and the pulley 7 can realize the position movement of the case 1 relative to the ground.

[0032] There is a distance between the side wall of the chassis 1 and the inner wall of the protective frame 2, and this distance forms an air duct, so that the wind that originally entered from the ground now enters from the top opening of the protective frame 2, which can effectively prevent the dust on the floor from being directly sucked into the chassis 1. In addition, the pad 3 can ensure the smooth flow of the air inlet channel.

[0033] In order to reduce the dust covering the bottom wall of the protective frame 2, the inner top surface of the protective frame 2 is composed of two connected inclined surfaces, and the end of the two inclined surfaces closer to each other is higher, so that the dust falling on the protective frame 2 will accumulate on both sides, thereby staying away from the air inlet at the bottom of the chassis 1, reducing the dust entering the chassis 1.

[0034] like Figure 2 As shown, in a preferred embodiment, a filter screen 4 is provided inwardly at the opening edge of the protective frame 2, the filter screen 4 is hinged to the opening edge of the protective frame 2, and the movable end of the filter screen 4 can be overlapped on the side wall of the chassis 1, thereby achieving the effect of filtering dust. In some embodiments, the filter screen 4 is transparent, and the transparent filter screen 4 is compatible with most current transparent chassis 1, ensuring the visual effect of the transparent chassis 1.

[0035] like Figure 1As shown, for the case where the floor at home is relatively clean, a spare air duct 5 is provided through the bottom surface of the protective frame 2, and a closing member 6 is movably provided on the spare air duct 5. The cross-section of the closing member 6 is in the shape of "π". By directly removing the closing member 6, air can enter from the bottom of the chassis 1, making the protective frame 2 applicable to different environments.

[0036] In summary, the present utility model mainly has the following beneficial effects: It can be directly placed on the protective frame 2. By means of the protective frame 2, the air duct at the bottom of the chassis 1 is changed. The air that originally entered from the ground upward now enters from the top opening of the protective frame 2, which can effectively prevent the dust on the floor from being directly sucked into the chassis 1. In addition, the heightening block 3 can ensure the smoothness of the air inlet channel.

[0037] For the case where the floor at home is relatively clean, by directly removing the closing member 6, air can enter from the bottom of the chassis 1, making the protective frame 2 applicable to different environments.

[0038] Although the embodiments of the present utility model have been shown and described, the specific embodiments are only explanations of the present utility model and not limitations thereof. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions and variations that do not make creative contributions to the embodiments according to needs, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
