Description

Technical Field

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

[0002] The computer host refers to the main body of the computer except for the input and output devices, mainly including the chassis and the computer internal devices such as the motherboard installed in the chassis. Since the main operating devices of the computer are installed in the chassis, these devices will generate a lot of heat when running, which may easily cause the temperature inside the chassis to be too high and affect the operation of the computer. Therefore, timely heat dissipation of the computer host is particularly important.

[0003] At present, most computer hosts use a cooling fan installed on the motherboard to help dissipate heat. Compared with the passive fanless design, heat dissipation through a cooling fan undoubtedly has greater advantages and can solve the heat dissipation problem of high-power computers.

[0004] The use of cooling fans for heat dissipation requires that the computer chassis have good air circulation to increase the heat exchange efficiency. Therefore, the chassis needs to be designed with vents. However, while the vents increase air circulation, they also cause foreign matter such as dust to enter the chassis. Especially when the cooling fan is stationary, dust will be attached to the cooling fan due to static electricity. Over time, the dust accumulated on the cooling fan will cause the cooling fan to malfunction or stop running, resulting in a high maintenance rate for the computer.

[0005] In order to prevent foreign objects such as dust from entering the computer chassis through the vents, the industry often uses a method of installing filters on the vents to block the entry of foreign objects. However, this setting will inevitably affect the circulation of air, thereby reducing the heat dissipation efficiency.

[0006] Therefore, how to improve the dust-proof effect of the computer host without affecting the air circulation is an urgent problem to be solved. Summary of the invention

[0023] In order to further illustrate the technical means and effects adopted by the present invention, the preferred embodiments of the present invention and the accompanying drawings are described in detail below.

[0024] like Figure 1-Figure 4 As shown, the utility model provides a computer host 1, including a chassis 10 and a motherboard 20 arranged in the chassis 10, and a cooling fan 21 is provided on the motherboard 20. The chassis 10 includes a chassis body 11 and a dustproof mechanism 12, and a plurality of first air outlets 111 are provided on the chassis body 11 at positions corresponding to the cooling fan 21.

[0025] like Figure 2 and Figure 3 As shown, the dustproof mechanism 12 includes a vent cover 121, two guide rails 122, at least one spring 123 and an electromagnet module 124. The two guide rails 122 are arranged on the chassis body 11 and are located on both sides of the plurality of first air outlets 111. The vent cover 121 can be slidably mounted on the two guide rails 122 along the two guide rails 122. The vent cover 121 is provided with a plurality of second air outlets 1211 and a plurality of shielding portions 1212 corresponding to the plurality of first air outlets 111. The plurality of second air outlets 1211 and the plurality of shielding portions 1212 are alternately arranged between the first end 1213 and the second end 1214 of the vent cover 121 which are arranged opposite to each other. At least one groove 1215 is provided on the end surface of the first end 1213 of the vent cover 121 corresponding to the at least one spring 123, and a positioning column 1216 is convexly provided on the bottom surface of each of the grooves 1215. An iron block 1217 is also installed at the first end 1213. The electromagnet module 124 is disposed on the chassis body 11 and adjacent to the first end 1213 of the vent cover 12, and the electromagnet module 124 is electrically connected to the main board 20. Each of the at least one spring 123 is sleeved on the positioning column 1216 in the corresponding groove 1215, with one end thereof abutting against the bottom surface of the corresponding groove 1215, and the other end abutting against the electromagnet module 124.

[0026] When the electromagnet module 124 is powered off, the multiple shielding parts 1212 of the air hole cover 121 respectively shield the multiple first air outlets 111; when the electromagnet module 124 is powered on, the electromagnet module 124 attracts the iron block 1217, thereby driving the air hole cover 121 to slide along the two guide rails 122 to the multiple second air outlets 1211 and respectively connect with the multiple first air outlets 111, and the at least one spring 123 is in a compressed state.

[0027] That is to say, the computer host 1 of the utility model can, through the setting of the dustproof mechanism 12, not only be able to shield the multiple first air outlets 111 respectively by the multiple shielding parts 1212 of the air hole cover 121 when the computer host 1 is not working, that is, the mainboard 20 cuts off the power to the electromagnet module 124, so as to prevent dust and other debris from entering the chassis 10 from the multiple first air outlets 111; and when the computer host 1 starts to work, that is, the mainboard 20 supplies power to the electromagnet module 124, so that the electromagnet module 124 generates an attraction force on the iron block 1217, thereby The air hole cover 121 is driven to slide along the two guide rails 122 toward the direction of the electromagnet module 124, so that the multiple second air outlets 1211 are respectively connected with the multiple first air outlets 111 to ensure the air circulation of the chassis 10 when the computer host 1 is working. At this time, the spring 123 is in a compressed state. Therefore, once the motherboard 20 stops supplying power to the electromagnet module 124, the air hole cover 121 will be restored to the state where the multiple shielding parts 1212 respectively cover the multiple first air outlets 111 under the action of the elastic restoring force of the spring 123.

[0028] It can be seen that the computer host 1 of the present invention can have a better dust-proof effect without affecting the air circulation.

[0029] Furthermore, the two guide rails 122 and the electromagnet module 124 can be arranged on the inner wall of the chassis body 11, so that the dustproof mechanism 12 is arranged on the inner wall of the chassis body 11, so as to facilitate the electrical connection of the electromagnet module 124 to the main board 20 and ensure the overall appearance of the chassis 10 is simple. Of course, the utility model is not limited to this, and the two guide rails 122 and the electromagnet module 124 can also be arranged on the outer wall of the chassis body 11 as needed.

[0030] Two guide arms 1221 are protruded from the inner side surfaces of the two guide rails 122, and slide grooves 1218 are formed on the opposite side walls of the vent cover 121 corresponding to the two guide arms 1221. The guide arms 1221 of each guide rail 122 extend into the corresponding slide grooves 1218. Through the cooperation between the slide grooves 1218 and the guide arms 1221, the vent cover 121 is installed on the two guide rails 122, located between the two guide rails 122, and can slide along the two guide rails 122. Further, one end of each slide groove 1218 extends through the end surface of the second end 1214 of the vent cover 121, so that the guide arm 1221 can be inserted into the slide groove 1218; the other end of each slide groove 1218 extends to the stopper 1219 provided at the first end 1213 of the vent cover 121, so as to limit the vent cover 121. In a preferred embodiment, the cross section of each guide rail 122 is in an inverted L shape.

[0031] It is noted here that the sliding fit structure of the guide rail 122 and the air vent cover 121 of the utility model is not limited to the above. For example, the slide groove can be arranged on the guide rail 122, and the guide arm is correspondingly arranged on the two side walls of the air vent cover 121, which can also realize the sliding fit between the air vent cover 121 and the guide rail 122.

[0032] Further, the dustproof mechanism includes two springs 123, and two grooves 1215 are provided on the end surface of the first end 1213 of the vent cover 121 corresponding to the two springs 123, and the two springs 123 are respectively sleeved on the positioning posts 1216 in the corresponding grooves 1215, and the iron block 1217 is located between the two grooves 1215. Preferably, the vent cover 121 includes a top surface 131 and a bottom surface 132 that are arranged oppositely, and when the vent cover 121 is installed on the two guide rails 122, the top surface 131 is close to the chassis body 11, and the iron block 1217 is provided at the first end 1213 and located on the bottom surface 132 of the vent cover 121.

[0033] In a preferred embodiment, the electromagnet module 124 is fixedly mounted on the chassis body 11 by glue dispensing, and the iron block 1217 is also fixedly mounted on the air hole cover 121 by glue dispensing.

[0034] When installing the air hole cover 121, spring 123 and electromagnet module 124 of the dustproof mechanism 12 on the chassis body 11, the air hole cover 121 can be first installed on the chassis body 11 and located between the two guide rails 122 through the cooperation of the sliding grooves 1218 on the two side walls of the air hole cover 121 and the two guide rails 122 set on the chassis body 11; then the springs 123 are respectively mounted on the positioning columns 1216 in the corresponding grooves 1215, and the electromagnet module 124 is fixed to the chassis body 11 by glue, so that the spring 123 can simultaneously abut against the bottom surface of the groove 1215 and the electromagnet module 124. The electromagnet module 124 is electrically connected to the main board 20. When the electromagnet module 124 is not powered on, the vent cover 121 maintains a state where the multiple shielding parts 1212 respectively shield the multiple first air outlets 111. When the computer host 1 starts working, the main board 20 supplies power to the electromagnet module 124, and the electromagnet module 124 generates an attraction force on the iron block 1217, thereby driving the vent cover 121 to slide along the two guide rails 122 toward the electromagnet module 124, so that the multiple second air outlets 1211 are respectively connected to the multiple first air outlets 111. At this time, the spring 123 is in a compressed state. Once the mainboard 20 stops supplying power to the electromagnet module 124, the vent cover 121 will, under the elastic restoring force of the spring 123, return to the state where the multiple shielding portions 1212 respectively shield the multiple first air outlets 111, and at this time, the stop portion 1219 abuts against the guide arm 1221 of the guide rail 122 to limit the vent cover 121.

[0035] Specifically, in Figure 1 and Figure 2 In the illustrated embodiment, the chassis body 11 may include a lower cover 112, an upper cover 113, and a panel 114. The upper cover 113 may be covered on the lower cover 112, thereby forming a receiving space between the upper cover 113 and the lower cover 112, and the panel 114 is installed on the front side of the upper cover 113. The mainboard 20 is disposed in the receiving space. Since the cooling fan 21 disposed on the mainboard 20 faces the upper cover 113, the plurality of first air outlets 111 are disposed on the upper cover 113 and correspond to the cooling fan 21 to ensure air circulation when the cooling fan 21 is working. In this embodiment, the two guide rails 122 and the electromagnet module 124 are specifically disposed on the inner wall of the upper cover 113, and the air hole cover 121 is also installed on the inner wall of the upper cover 113. Figure 3 and Figure 4 The electromagnet module 124 is electrically connected to the electrical connector 22 disposed on the mainboard 20 .

[0036] The computer host 1 further includes an I / O board 30 . The I / O board 30 is also disposed in the receiving space and is electrically connected to the main board 20 .

[0037] It is explained here that in the above-mentioned embodiment of the utility model, the multiple first air outlets 111 are strip-shaped air outlets, and the multiple first air outlets 111 are arranged in two rows, and the first air outlets in each row are arranged in parallel, and the two guide rails 122 are arranged on both sides of the multiple first air outlets 111, and are arranged perpendicular to the multiple first air outlets 111. Correspondingly, the multiple second air outlets 1211 are strip-shaped air outlets, and correspond to the multiple first air outlets 111 respectively. It can be understood that the shape and arrangement of the first air outlet 111 are not limited to this. Therefore, the arrangement of the multiple second air outlets and the multiple shielding parts of the utility model can also be changed according to the specific arrangement of the first air outlet on the chassis body, as long as the multiple first air outlets can be connected and shielded as the position of the air hole cover 121 on the chassis body 11 changes.

[0038] In summary, the computer host of the present invention is provided with a dustproof mechanism, so that when the electromagnet module of the dustproof mechanism is in a power-off state (the computer host is not working), the multiple shielding parts of the air hole cover of the dustproof mechanism can respectively shield the multiple first air outlets on the chassis body to prevent dust and other debris from entering the chassis from the first air outlets, and when the electromagnet module obtains power supply from the mainboard (the computer host is working), the electromagnet module attracts the iron block arranged on the air hole cover, driving the air hole cover to slide along the guide rail toward the electromagnet module, so that the multiple second air outlets of the air hole cover are respectively connected with the multiple first air outlets on the chassis body, thereby ensuring the air circulation in the chassis when the computer host is working. Therefore, the computer host of the present invention can have a better dustproof effect without affecting the air circulation.

[0039] As described above, for ordinary technicians in this field, various other corresponding changes and modifications can be made according to the technical scheme and technical concept of the utility model, and all these changes and modifications should fall within the protection scope of the claims of the utility model.
