Description

Technical Field

[0001] This application relates to the technical field of laptop computers, and particularly to a dust removal mechanism for the heat dissipation module of a laptop computer. Background Art

[0002] Currently, the heat dissipation structures of laptop computers generally adopt the following structure: Heat-generating components with relatively high heat generation inside the computer, such as the CPU and GPU, use heat pipes to conduct their heat to the heat dissipation fins at the corner positions of the laptop computer together, and then use a heat dissipation fan and a duct structure to generate a directional high-speed air flow. When contacting the heat dissipation fins, it can take away the heat and blow it out of the computer case.

[0003] When a laptop computer is in use, a large amount of dust will accumulate on the heat dissipation fins and the heat dissipation fan, thereby reducing the ventilation and heat dissipation effect of the laptop. Currently, dust removal can only be achieved by disassembling the laptop computer. However, a large number of existing laptops are all-in-one machines, which are relatively difficult to disassemble, and are prone to damage to the internal electronic components after being opened. In order to reasonably improve this problem, this application proposes a dust removal mechanism for the heat dissipation module of a laptop computer. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0028] As Figures 1-5As shown in the figure, a dust removal mechanism for a notebook computer cooling module proposed in an embodiment of the present application includes a computer base 1 and an installation cavity 2 constructed therein. The main board of the notebook computer is installed in the installation cavity 2, and further includes:

[0029] Slots 3, which are symmetrically constructed on both sides of the computer base 1. The slots 3 on both sides extend relatively. In the present application, the optimal number of slots 3 is four, and they are respectively close to the four corners of the computer base 1. A dust-proof plate 4 is provided on the side of the slot 3 facing the installation cavity 2. The installation cavity 2 is connected to the slot 3 through the dust-proof plate 4. Most of the dust in the air entering the installation cavity 2 through the slot 3 can be intercepted by the dust-proof plate 4;

[0030] A plurality of air inlets 5, which are constructed at the bottom of the computer base 1. The sides of the slots 3 away from the installation cavity 2 are all penetrated by the air inlets 5. Because the computer base 1 itself has pads, when the computer is placed, the air inlets 5 are not easily blocked, and air can enter the slots 3 through the air inlets 5;

[0031] An air outlet 6, which is opened on the other side of the computer base 1, and its end penetrates the installation cavity 2. The air in the installation cavity 2 can be discharged through the air outlet 6. A heat dissipation component 7 is provided at the end of the air outlet 6. The heat dissipation component 7 is a prior art, which includes heat dissipation fins 701 covering the end of the air outlet 6, and a heat dissipation fan 702 installed on the other side of the heat dissipation fins 701. The heat dissipation fins 701 are connected to the heating elements in the installation cavity 2 through a heat conduction tube 703. When the heat dissipation fan 702 operates, after the air passes through the heat dissipation fins 701, it can be discharged from the air outlet 6, thereby taking away the heat inside. Subsequently, the air inlets 5 can suck air;

[0032] A baffle 8, which is used to close the slot opening of the slot 3 so that external air is not easily introduced into the slot 3 through the slot opening of the slot 3. A slot 801 is constructed on its outer side. This structure is similar to the concave handle of a drawer. The baffle 8 can be pulled to move through the slot 801. Connecting plates 802 extending towards the ends of the slot 3 are constructed at both ends of the baffle 8. The two are movably inserted into the slot 3. The connecting plates 802 are in sliding contact with the inner wall of the slot 3, and a cleaning component 803 is provided at their ends, which is used to clean the filtering surface of the dust-proof plate 4. When the baffle 8 closes the slot opening of the slot 3, the cleaning component 803 is located at the end of the slot 3 away from the slot opening. When the baffle 8 is pulled out of the slot 3 through the slot 801, the cleaning component 803 can clean the filtering surface of the dust-proof plate 4 and take out the cleaned dust from the slot 3 together;

[0033] A positioning mechanism 9, which is arranged on the computer base 1 and is used to fix the baffle 8. By fixing the baffle 8, when the notebook computer is moved, the baffle 8 is not easily separated from the slot 3;

[0034] In this application, by adopting the design of the dust-proof plate 4, when the outside air enters the slot 3 from the air inlet hole 5 and passes through the slot 3 into the installation cavity 2, the dust in the air can be intercepted by the dust-proof plate 4. Subsequently, by releasing the fixing of the baffle 8 by the positioning mechanism 9 and pulling the baffle 8 out of the slot 3 through the slot 801, at this time, the cleaning component 803 can clean the filtering surface of the dust-proof plate 4 and take out the cleaned dust from the slot 3. Compared with the prior art, in this application, the dust is intercepted by the dust-proof plate 4, which can effectively reduce the influence of dust on the heat dissipation component 7. Subsequently, by moving the baffle 8, the dust-proof plate 4 can be cleaned by the cleaning component 803 without disassembling the laptop, which is relatively convenient and fast and has practicability.

[0035] As Figures 2-5 shown, in some embodiments, the cleaning component 803 includes a mounting plate 8031, which is connected to the opposite sides of the two connecting plates 802. A cleaning block 8032 is mounted on the side facing the baffle 8. The cleaning block 8032 is a silica gel block with a relatively soft texture, and dust is not easily attached to it. It has the advantage of long service life while being convenient for cleaning. The opposite sides of the cleaning block 8032 are respectively in movable contact with the dust-proof plate 4 and the inner wall of the slot 3. Here, the inner wall of the slot 3 is penetrated by the air inlet hole 5. When the cleaning block 8032 moves, it can rub against the dust-proof plate 4 and the air outlet end of the air inlet hole 5, and take out the dust attached to it from the notch of the slot 3.

[0036] As Figure 4 and Figure 5 shown, in some embodiments, an arc surface 8033 is formed on the side of the cleaning block 8032 facing the baffle 8. The design of the arc surface 8033 is used to guide the movement of the cleaning block 8032, so as to reduce the resistance when it moves towards the notch of the slot 3, so as to facilitate its movement.

[0037] As Figure 4 and Figure 5 shown, in some embodiments, the ends of the two connecting plates 802 are both away from the mounting plate 8031, and connecting blocks 8021 are formed on their opposite sides. The connecting blocks 8021 are connected to the mounting plate 8031. An arc surface 8023 is formed on the side of the connecting block 8021 away from the connection end of the mounting plate 8031 and the connecting plate 802. Since the cleaning block 8032 adopts the method of friction cleaning, the resistance it receives when moving is relatively large. Through such a design, the connection strength between the mounting plate 8031 and the connecting plate 802 can be improved, so that it is not easy to deform during the movement of the cleaning block 8032.

[0038] As Figure 4 and Figure 5As shown, in some embodiments, the ends of the two connecting plates 802 are each configured with a guiding surface 8022. The guiding surface 8022 is an arc-shaped guiding surface 8022, and the guiding surface 8022 is provided on the opposite sides of the two connecting plates 802. The distance between the two guiding surfaces 8022 gradually decreases in the direction from the baffle 8 towards the mounting plate 8031. With such a design, the alignment of the two connecting plates 802 with the slot opening of the slot 3 is simple, facilitating the insertion of the connecting plates 802 into the slot 3.

[0039] As Figures 2-4 shown, in some embodiments, the slot 3 includes transverse plates 301 symmetrically configured on the inner wall of the mounting cavity 2. There is a distance between the two transverse plates 301, and their ends are connected by a vertical plate 302. The vertical plate 302 is away from the slot opening of the slot 3. Opposite grooves of the two transverse plates 301 are each configured with a sliding groove 303 extending along its length direction. The dust-proof plate 4 is movably inserted into the sliding groove 303. The two transverse plates 301, the vertical plate 302, the dust-proof plate 4, and the inner wall of the mounting cavity 2 cooperate to form the slot 3, and its end is fixed to the computer base 1 through a fixing member 304. The dust on the dust-proof plate 4 cannot be completely cleaned by the friction cleaning method. After long-term use, the dust that has not been removed is likely to firmly adhere to the dust-proof plate 4, affecting the movement of the cleaning block 8032 and increasing the wear generated by its movement. With such a design, after removing the fixing of the dust-proof plate 4 by the fixing member 304, the dust-proof plate 4 can be pulled out of the sliding groove 303 to clean the stubborn dust on it.

[0040] As Figure 2 shown, in some embodiments, the fixing member 304 includes a fixing block 3041 configured at the end of the dust-proof plate 4. A receiving groove 3042 is configured on the outer side of the computer base 1. The fixing block 3041 is fixed in the receiving groove 3042 through a bolt assembly 3043. The receiving groove 3042 can protect the fixing block 3041 and the bolt assembly 3043 from being easily damaged. The design of using the bolt assembly 3043 has the advantages of convenient installation and simple disassembly.

[0041] As Figure 2 and Figure 3As shown, in some embodiments, the positioning mechanism 9 includes a sliding groove 901 formed on the inner wall of the slot 3, in which a plug post 902 is slidably installed. A cylindrical groove 903 is formed on the baffle 8, and the cylindrical groove 903 is used to accommodate the plug post 902. A push block 904 is formed on one side of the plug post 902, and anti-slip lines are formed on the outer surface of the push block 904, which penetrates the computer base 1. A compression spring 905 is arranged in the sliding groove 901 and abuts against the end of the plug post 902. The compression spring 905 is used to provide a thrust force to force the plug post 902 to extend out of the sliding groove 901. Under the action of this thrust force, the plug post 902 can be inserted into the cylindrical groove 903 to limit the movement of the baffle 8. By pushing the push block 904, the plug post 902 can be moved to separate it from the cylindrical groove 903, thereby releasing the fixation of the baffle 8.

[0042] The foregoing description of the disclosed embodiments enables those skilled in the art to practice or use the present application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
