Description

Technical Field

[0001] This utility model belongs to the field of laptop stand technology, and specifically relates to an adjustable laptop cooling stand. Background Technology

[0002] With the widespread use of laptops, cooling stands have become an important accessory for improving device stability and user experience. Existing laptop cooling stands mainly promote airflow through metal mesh or fan structures to alleviate the high temperature problem during device operation.

[0003] However, current mainstream cooling pads have significant shortcomings in terms of structural adaptability and portability. Traditional cooling pads use a one-piece frame design with a fixed support width. Due to the large differences in laptop sizes, a single-size cooling pad cannot be compatible with different models. Smaller devices will waste space when placed on it; larger devices may be partially suspended, leading to unstable support, uneven heat dissipation, and even the risk of the device slipping. At the same time, most existing cooling pads have rigid frame structures, and their folded size is still large, making them difficult to store in a backpack. They are not well-suited to the mobility and portability advantages of laptops and cannot meet the lightweight needs of mobile office scenarios.

[0004] Therefore, an adjustable-size laptop cooling pad is needed. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable laptop cooling stand, thereby overcoming the shortcomings of existing laptop cooling stands that cannot be adjusted to accommodate laptops of different sizes and are inconvenient to store.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Next, the working principle of this embodiment will be described in detail so that those skilled in the art can better understand this utility model:

[0029] An adjustable laptop cooling stand includes a first base 1, a second base 2, a first support rod 3, a second support rod 4, a first connecting rod 5, a second connecting rod 6, and an adjusting rod 7. A fixing block 8 is provided at one end of the first base 1, and the fixing block 8 is rotatably connected to one end of the first support rod 3. A baffle 9 is provided on the working surface of the first support rod 3 and the second support rod 4 that contacts the laptop, and the baffle 9 is used to limit the laptop's movement and prevent it from sliding down.

[0030] The first support rod 3 and the second support rod 4 are respectively provided with a first sliding groove 10 and a second sliding groove 11. One end of the first connecting rod 5 is rotatably connected to the end of the first sliding groove 10 near the fixed block 8, and one end of the second connecting rod 6 is rotatably connected to the end of the second sliding groove 11 near the fixed block 8. Guide grooves 16 are provided on the inner sidewalls of both the first sliding groove 10 and the second sliding groove 11. The other end of the first connecting rod 5 is slidably connected to the guide groove 16 of the second sliding groove 11, and the other end of the second connecting rod 6 is slidably connected to the guide groove 16 of the first sliding groove 10. Both sliding connections are interference fits, requiring a certain amount of force to drive, ensuring the stability of the heat sink. The cross connection of the first connecting rod 5 and the second connecting rod 6 allows for width adjustment of the first support rod 3 and the second support rod 4, accommodating laptops of different sizes and avoiding situations where the heat sink is unstable due to an oversized laptop or wastes space due to a small laptop. Simultaneously, the first connecting rod 5 and the second connecting rod 6 ensure the stability between the first support rod 3 and the second support rod 4.

[0031] The second connecting rod 6 has a first clearance groove for avoiding the first connecting rod 5. The first connecting rod 5 passes through the clearance groove and connects to the second support rod 4. The thickness of the first connecting rod 5 is equal to the thickness of the first clearance groove. Therefore, the first connecting rod 5 and the second connecting rod 6 are in a spatially overlapping state, which can reduce the space occupation rate and reduce the volume when stored. The first base 1 and the second base 2 both have positioning grooves 12. The side of the first support rod 3 and the second support rod 4 away from the baffle 9 are respectively rotatably connected to one end of the adjusting rod 7. The other end of the adjusting rod 7 cooperates with the positioning groove 12 to fix the first support rod 3 and the second support rod 4, thereby raising the laptop to a certain angle and suspending the bottom of the laptop, which makes it easier for the laptop to draw in outside cold air for heat dissipation.

[0032] The thickness of the first support rod 3 and the second support rod 4 is equal to the thickness of the fixing block 8. When the first support rod 3 and the second support rod 4 are laid flat and attached to the first base 1 and the second base 2 respectively, the first support rod 3, the second support rod 4 and the fixing block 8 are located on the same plane. The thickness of the two ends of the first connecting rod 5 and the second connecting rod 6 is equal to the thickness of the first sliding groove 10 and the second sliding groove 11. Therefore, the first connecting rod 5 and the second connecting rod 6 can be completely stored in the first sliding groove 10 and the second sliding groove 11. Therefore, this utility model is convenient for storage and will not cause damage to other items due to unevenness.

[0033] Multiple positioning slots 12 are arrayed on both the first base 1 and the second base 2. The multiple positioning slots 12, together with the adjusting rod 7, can realize multi-angle adjustment of the first support rod 3 and the second support rod 4, thereby meeting different user needs and improving practicality.

[0034] Both the first base 1 and the second base 2 are provided with a storage groove 13. The depth of the storage groove 13 is the same as the thickness of the adjusting rod 7. The storage groove 13 can completely store the adjusting rod 7 inside the storage groove 13. Therefore, the adjusting rod 7 will not affect the first support rod 3 and the second support rod 4 from fitting together with the first base 1 and the second base 2 respectively, making it convenient to store.

[0035] The auxiliary support unit includes a third link 14 and a fourth link 15, used to improve the stability of the first base 1 and the second base 2. The end of the first base 1 near the fixing block 8 is rotatably connected to one end of the third link 14, and the end of the second base 2 near the fixing block 8 is rotatably connected to the end of the fourth link 15. Guide grooves 16 are respectively provided on the first base 1 and the second base 2. The other end of the third link 14 is slidably connected to the guide groove 16 on the second base 2, and the other end of the fourth link 15 is slidably connected to the guide groove 16 on the first base 1. Both sliding connections use interference fits, requiring a certain amount of force to drive, ensuring the stability of the heat sink. A second clearance groove is provided on the third link 14, through which the fourth link 15 passes. Therefore, the first link 5 and the second link 6 are spatially overlapping, reducing space occupancy and storage volume.

[0036] The bottom ends of the fourth link 15 are provided with pads 17. The two sides of the pads 17 and the two sides of the third link 14 are located on the same horizontal plane to prevent the heat sink from shaking and ensure the stability of the heat sink.

[0037] Positive and negative magnets are embedded in the side walls of the first base 1 and the second base 2, which are close to each other. Since the magnetic fields of the positive and negative magnets are in opposite directions, they attract each other. When the heat sink is stored, the positive and negative magnets stably connect the first base 1 and the second base 2, restricting the freedom of movement of the components and facilitating storage. Positive magnets can also be installed on the first support rod 3 and the second support rod 4, and corresponding negative magnets can be installed on the first base 1 and the second base 2 to prevent the first support rod 3 and the second support rod 4 from rotating freely when stored.

[0038] The rotating unit includes a fixed disk 18, a connecting sleeve 21, a turntable 19, and a connecting post 20. The turntable 19 is rotatably mounted on the fixed disk 18, and the connecting post 20 is vertically mounted on the side of the turntable 19 away from the fixed disk 18. The connecting sleeve 21 is embedded in the midpoint of the third connecting rod 14, and a through hole is provided on the fourth connecting rod 15 for rotatable connection with the outer wall of the connecting sleeve 21. The connecting post 20 is a splined shaft, and a corresponding keyway is provided on the inner wall of the connecting sleeve 21. By fitting the connecting sleeve 21 onto the connecting post 20, the first base 1 and the second base 2 can rotate synchronously with the turntable 19, allowing the orientation of the laptop to be adjusted as needed, thus improving the practicality of this invention. Furthermore, the connecting sleeve 21 and the connecting post 20 are designed for quick disassembly and assembly; the rotating unit can be detached for easy storage when the laptop needs to be moved.

[0039] On the side of the turntable 19 closest to the fixed plate 18, multiple spherical grooves 22 are arranged in a circular array around the center. On the side of the fixed plate 18 closest to the turntable 19, multiple corresponding spherical protrusions 23 are arranged in a circular array around the center. The spherical protrusions 23 engage with the spherical grooves 22 to lock the turntable 19, preventing it from rotating arbitrarily. When the turntable 19 is rotated, the spherical protrusions 23 disengage from the spherical grooves 22, causing elastic deformation of both the turntable 19 and the fixed plate 18. When the spherical protrusions 23 re-engage with the spherical grooves 22, the turntable 19 is locked again. Therefore, the engagement of the spherical protrusions 23 and the spherical grooves 22 allows for multi-level adjustment of the turntable 19.

[0040] The method of using this utility model is as follows: The first base 1 and the second base 2 are unfolded according to the actual width of the laptop. During the unfolding process, the first connecting rod 5, the second connecting rod 6, the third connecting rod 14, and the fourth connecting rod 15 will rotate crosswise. Then, the first support rod 3 and the second support rod 4 are rotated around the fixing block 8 to a suitable angle. One end of the rotating adjusting rod 7 is inserted into the positioning groove 12 for fixation. Finally, the laptop can be placed on the first support rod 3 and the second support rod 4 for use. When this utility model needs to be stored, simply bring the first support rod 3, the second support rod 4, the first base 1, and the second base 2 together. At this time, the first connecting rod 5 and the second connecting rod 6 will be located in the first sliding groove 10 and the second sliding groove 11. Simultaneously, the storage groove 13 can store the adjusting rod 7, transforming the utility model into a rectangular object for easy storage.
