Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation fans for electronic products, and particularly relates to a laptop fan housing which is convenient for disassembly and assembly. Background Art

[0002] The laptop fan housing is an important part of the laptop heat dissipation system. It not only protects the fan from external damage, but also participates in the conduction and dissipation of heat. The materials of the laptop fan housing are diverse, commonly including plastics, aluminum alloys, etc. The design of the fan housing ensures that the heat generated by the fan can be discharged smoothly, avoiding heat accumulation inside. Usually, the housing will adopt designs such as heat dissipation holes and heat dissipation fins to increase the heat dissipation area and improve the heat dissipation efficiency, while protecting the fan from external impacts and vibrations.

[0003] However, the fixing methods of traditional laptop fan housings are diverse, including screw fixing, snap fixing, plastic nail fixing, etc. Different fixing methods may require different tools and methods for disassembly. If the correct steps are not followed or appropriate tools are not used during the disassembly process, it may cause damage to the fan housing or related components, thereby increasing the difficulty of subsequent disassembly. For example: When disassembling a fan housing fixed with plastic nails, tools such as a knife or a hot air gun may be required to cut or soften the plastic nails, thus increasing the disassembly difficulty. Summary of the Utility Model

[0004] The utility model discloses a laptop fan housing which is convenient for disassembly and assembly, aiming to solve the technical problem that the fixing methods of traditional laptop fan housings are diverse, including screw fixing, snap fixing, plastic nail fixing, etc. Different fixing methods may require different tools and methods for disassembly. If the correct steps are not followed or appropriate tools are not used during the disassembly process, it may cause damage to the fan housing or related components, thereby increasing the difficulty of subsequent disassembly.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A laptop fan housing which is convenient for disassembly and assembly, comprising a computer bottom plate and a fan housing body, further comprising:

[0007] Fixing mechanism: used to install and fix the fan housing body. The fixing mechanism includes four mounting bases. Inside the four mounting bases, there is a connecting clamping plate. Inside the connecting clamping plate, there is a support plate. Four limiting clamping plates are hinged on the top outer wall of the support plate. The top inner wall of the connecting clamping plate is threadedly connected with a limiting sleeve. Inside the limiting sleeve, there is a connecting rod. One end of the connecting rod penetrates through the top outer wall of the support plate. The limiting sleeve is sleeved on the tops of the four limiting clamping plates. A limiting strip is provided at one end of the connecting rod away from the support plate. The four limiting strips are respectively located at the four corners of the fan housing body;

[0008] Limiting mechanism: located between the computer base plate and the fan housing body.

[0009] Adopting the above technical solution can reduce the fixing steps of the fan housing body of the notebook computer, reduce the subsequent disassembly difficulty, and avoid the loss of fixing parts and damage to the fan housing body or related components. Specifically, first fix the mounting base on the upper surface of the computer base plate, then insert the connecting rod into the inside of the connecting clamping plate, and then rotate the connecting rod and the limiting sleeve clockwise. Since the limiting sleeve is threadedly connected with the connecting clamping plate, the limiting sleeve will rotate and descend on the inner wall of the connecting clamping plate. The bifurcated parts of the four limiting clamping plates are all provided with conical surfaces, which cooperate with the inner conical surface of the limiting sleeve to continuously tighten, so as to realize the clamping of the connecting rod. Thus, the limiting strip correspondingly rotates to one of the corners of the fan housing body and limits and clamps the upper surface of the fan housing body. If the cooling fan needs to be repaired, then rotate the connecting rod, the limiting strip and the limiting sleeve counterclockwise. Thus, the limiting sleeve will lift upward, and the four limiting clamping plates will automatically disperse due to the loss of the clamping force. Then the connecting rod, the limiting strip and the limiting sleeve can be smoothly pulled out, and at the same time, the force for clamping and limiting the four corners of the fan housing body is also lost.

[0010] In a preferred solution, the limiting mechanism includes a mounting frame. On the top outer wall of the computer base plate and on the inner walls of both sides of the mounting frame, there are mounting brackets. Two limiting grooves and a mounting plate are provided on the top outer wall of the mounting bracket. The two ends of the bottom of the mounting plate are respectively inserted into the inner walls of the two limiting grooves. A limiting component is provided on one side outer wall of the mounting plate. Two positioning plates are provided on the top outer wall of the mounting plate and on the outer wall of the fan housing body respectively. Adjacent two positioning plates are fixedly connected by bolts.

[0011] When it is necessary to fix the fan housing body to the computer base plate, first fix the mounting frame on the top outer wall of the computer base plate. Then, install the mounting brackets on the inner walls on both sides of the mounting frame and ensure that the positions of the limiting grooves are correct. Next, insert the two bottom ends of the mounting plate into the limiting grooves so that the mounting plate and the mounting brackets form a stable connection. At this time, the position of the mounting plate can be adjusted to match the position of the fan housing body. Then, use the limiting component to fix one side of the mounting plate to the computer base plate. Finally, fix the adjacent two positioning plates (one is on the mounting plate and the other is on the fan housing body) together by bolts, thereby ensuring a stable connection between the fan housing body and the computer base plate.

[0012] In a preferred solution, the limiting component includes a fixed block and a mounting block. The fixed block is located on the outer wall of one side of the mounting plate. There are two return springs inside the fixed block. One end of each return spring is provided with a limiting block. A connecting column is fixedly connected to the outer wall of one side of the limiting block.

[0013] When it is necessary to fix the fan housing body on the mounting plate, first place the fan housing body in a proper position to align it with the positioning plate on the mounting plate. Then, manually move the two connecting columns closer to each other. At this time, the limiting block will move under the action of an external force, and at the same time, the return spring will deform and store energy. When the connecting columns are completely abutted against both sides of the fixed block, the operator releases the squeezing force on the two connecting columns. At this time, the return spring will release energy and push the limiting block back to its initial position, so that one end of the two connecting columns will move away from each other and abut against the inner walls on both sides of the mounting block, thereby ensuring a stable connection between the connecting columns and the fan housing body. Such a setting realizes the stable fixation of the fan housing body and has a certain anti-vibration and impact resistance, further improving the stability and reliability of the entire heat dissipation system.

[0014] As can be seen from the above, a notebook computer fan housing that is convenient for disassembly and assembly includes a computer base plate and a fan housing body, and further includes:

[0015] A fixing mechanism: used to install and fix the fan housing body. The fixing mechanism includes four mounting bases. There are connecting clamping plates inside the four mounting bases. There is a support plate inside the connecting clamping plate. Four limiting clamping plates are hinged to the top outer wall of the support plate. The inner wall of the top of the connecting clamping plate is threadedly connected with a limiting sleeve. There is a connecting rod inside the limiting sleeve. One end of the connecting rod penetrates through the top outer wall of the support plate. The limiting sleeve is sleeved on the tops of the four limiting clamping plates. A limiting strip is provided at the end of the connecting rod away from the support plate. The four limiting strips are respectively located at the four corners of the fan housing body;

[0016] Limiting mechanism: It is located between the computer base plate and the fan housing body. The notebook computer fan housing provided by the present utility model is convenient for disassembly and assembly, which has the technical effects of reducing the fixing steps of the notebook computer fan housing body, reducing the subsequent disassembly difficulty, avoiding the loss of fixing parts, and preventing damage to the fan housing body or related components.

Detailed Description of the Embodiment

[0022] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Usually, the components of the embodiments of the present application described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application claimed, but only represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0023] A notebook computer fan housing that is easy to disassemble and assemble disclosed by the present utility model is mainly applied to scenarios where there are various fixing methods for traditional notebook computer fan housings, including screw fixing, snap fixing, plastic nail fixing, etc. Different fixing methods may require different tools and methods for disassembly. If the correct steps are not followed or appropriate tools are not used during the disassembly process, it may cause damage to the fan housing or related components, thereby increasing the difficulty of subsequent disassembly.

[0024] Referring to Figure 1 and Figure 3 , a notebook computer fan housing that is easy to disassemble and assemble, includes a computer bottom plate 1 and a fan housing body 6, and further includes:

[0025] A fixing mechanism: used to install and fix the fan housing body 6. The fixing mechanism includes four mounting bases 14. A connecting card plate 15 is provided inside the four mounting bases 14. A support plate 16 is provided inside the connecting card plate 15. Four limiting clamping plates 17 are hinged to the top outer wall of the support plate 16. A limiting screw sleeve 18 is threadedly connected to the top inner wall of the connecting card plate 15. A connecting rod 8 is provided inside the limiting screw sleeve 18. One end of the connecting rod 8 penetrates through the top outer wall of the support plate 16. The limiting screw sleeve 18 is sleeved on the tops of the four limiting clamping plates 17. A limiting strip 4 is provided at the end of the connecting rod 8 away from the support plate 16. The four limiting strips 4 are respectively located at the four corners of the fan housing body 6;

[0026] A limiting mechanism: located between the computer bottom plate 1 and the fan housing body 6.

[0027] Among them, the inner cross-section of the limiting screw sleeve 18 is an isosceles trapezoid structure. This setting facilitates the inner conical surface of the limiting screw sleeve 18 to fit with the forked conical surfaces of the four limiting clamping plates 17 when the limiting screw sleeve 18 is screwed clockwise, thereby aggregating the four limiting clamping plates 17 and further realizing the clamping of the connecting rod 8.

[0028] In the specific implementation process, the connecting rod 8 and the limiting strip 4 always remain perpendicular to each other.

[0029] Specifically, the working principle of the fixing mechanism is similar to that of an expansion bolt. First, the mounting base 14 is fixed on the upper surface of the computer base plate 1. Then, the connecting rod 8 is inserted into the inside of the connecting card plate 15. Next, the connecting rod 8 and the limit sleeve 18 are rotated clockwise. Since the limit sleeve 18 is threadedly connected to the connecting card plate 15, the limit sleeve 18 will rotate and descend on the inner wall of the connecting card plate 15. The bifurcated parts of the four limit clamping plates 17 are all provided with conical surfaces, which cooperate with the inner conical surface of the limit sleeve 18 to continuously tighten, thus achieving the clamping of the connecting rod 8. As a result, the limit strip 4 correspondingly rotates to one corner of the fan housing body 6 and clamps and limits the upper surface of the fan housing body 6. If the cooling fan needs to be repaired, then rotate the connecting rod 8, the limit strip 4 and the limit sleeve 18 counterclockwise. As a result, the limit sleeve 18 will lift upward. The four limit clamping plates 17 will automatically spread out due to the loss of the clamping force. Then, the connecting rod 8, the limit strip 4 and the limit sleeve 18 can be smoothly pulled out. At the same time, the force for clamping and limiting the four corners of the fan housing body 6 is also lost. This device can reduce the fixing steps for the fan housing body 6 of the notebook computer, reduce the subsequent disassembly difficulty, and avoid the loss of fixing parts and damage to the fan housing body 6 or related components.

[0030] Referring to Figure 1 and Figure 2 In a preferred embodiment, the limiting mechanism includes a mounting frame 2. Mounting brackets 11 are provided on the outer wall of the top of the computer base plate 1 and on the inner walls of both sides of the mounting frame 2. Two limiting grooves 12 and a mounting plate 9 are formed on the outer wall of the top of the mounting bracket 11. The two ends of the bottom of the mounting plate 9 are respectively inserted into the inner walls of the two limiting grooves 12. A limiting component is provided on one outer wall of the mounting plate 9. Two positioning plates 5 are provided on the outer wall of the top of the mounting plate 9 and on the outer wall of the fan housing body 6. Adjacent two positioning plates 5 are fixedly connected by bolts.

[0031] Specifically, when it is necessary to fix the fan housing body 6 to the computer base plate 1, first fix the mounting frame 2 on the outer wall of the top of the computer base plate 1. Then, install the mounting brackets 11 on the inner walls of both sides of the mounting frame 2 and ensure the correct position of the limiting grooves 12. Next, insert the two ends of the bottom of the mounting plate 9 into the limiting grooves 12 so that the mounting plate 9 forms a stable connection with the mounting brackets 11. At this time, the position of the fan housing body 6 can be adjusted to match the mounting plate 9. Then, use the limiting component to fix one side of the mounting plate 9 to the computer base plate 1. Finally, fixedly connect adjacent two positioning plates 5 (one is on the mounting plate 9 and the other is on the fan housing body 6) together by bolts, so as to ensure the stable connection between the fan housing body 6 and the computer base plate 1.

[0032] Referring to Figure 1 and Figure 4, in a preferred embodiment, the limiting component includes a fixed block 7 and a mounting block 10. The fixed block 7 is located on one outer wall of the mounting plate 9. Two reset springs 13 are arranged inside the fixed block 7. One end of each reset spring 13 is provided with a limiting block 19, and a connecting column 20 is fixedly connected to one outer wall of the limiting block 19.

[0033] Specifically, when it is necessary to fix the fan housing body 6 on the mounting plate 9, first place the fan housing body 6 in an appropriate position so that it is aligned with the positioning plate 5 on the mounting plate 9. Then, manually move the two connecting columns 20 closer to each other. At this time, the limiting block 19 will move under the action of an external force, and at the same time, the reset spring 13 will deform and store energy. When the connecting columns 20 are completely abutted against both sides of the fixed block 7, the operator releases the squeezing force on the two connecting columns 20. At this time, the reset spring 13 will release energy and push the limiting block 19 back to its initial position, so that one ends of the two connecting columns 20 will move away from each other and abut against the inner walls of both sides of the mounting block 10, thereby ensuring a firm connection between the connecting column 20 and the fan housing body 6. This setting realizes the firm fixation of the fan housing body 6, and at the same time has a certain anti-vibration and impact resistance, further improving the stability and reliability of the entire heat dissipation system.

[0034] Refer to Figure 1 and Figure 4 In a preferred embodiment, a notch is formed on one outer wall of the mounting frame 2, and the position of the mounting block 10 corresponds to that of the notch. The mounting block 10 has a "concave" structure. Four mounting holes are formed on the top outer walls of both the mounting frame 11 and the mounting plate 9, and the positions of the mounting holes correspond to the positions where the fixing mechanism is located.

[0035] Specifically, the shape and size of the notch are usually matched with the mounting block 10 to ensure that the fixed block 7 can be smoothly inserted and fixed in the notch. The mounting block 10 is designed with a "concave" structure, and this design enables the mounting block 10 to closely fit against the outer walls of both sides of the fixed block 7, thereby providing a stable support and fixing effect. The provided mounting holes corresponding to the positions where the fixing mechanism is located can accommodate relevant components in the fixing mechanism such as (connecting rod 8, limiting strip 4, etc.) to pass through and ensure that these can be correctly installed and positioned, reducing the possibility of installation errors.

[0036] Working principle: When in use, first fix the mounting base 14 on the upper surface of the computer base plate 1, then insert the connecting rod 8 into the inside of the connecting card plate 15, and then rotate the connecting rod 8 and the limit sleeve 18 clockwise. Since the limit sleeve 18 is threadedly connected to the connecting card plate 15, the limit sleeve 18 will rotate and descend on the inner wall of the connecting card plate 15. The bifurcated parts of the four limit clamping plates 17 are all provided with conical surfaces, which cooperate with the inner conical surface of the limit sleeve 18 to continuously tighten, thus realizing the clamping of the connecting rod 8. As a result, the limit strip 4 correspondingly rotates to one corner of the fan housing body 6 and clamps and limits the upper surface of the fan housing body 6. If the cooling fan needs to be repaired, then rotate the connecting rod 8, the limit strip 4 and the limit sleeve 18 counterclockwise. As a result, the limit sleeve 18 will lift upward, and the four limit clamping plates 17 will automatically spread out due to the loss of the clamping force. Then the connecting rod 8, the limit strip 4 and the limit sleeve 18 can be smoothly pulled out, and at the same time, the clamping and limiting force on the four corners of the fan housing body 6 is also lost, thus realizing the quick disassembly and assembly of the fan housing body 6.

[0037] The above is only the preferred specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. The substitution may be the substitution of some structures, devices, method steps, or a complete technical solution. Any equivalent substitution or change made according to the technical solution of the present invention and its inventive concept should be covered within the protection scope of the present invention.
