[0003] There are a wide variety of existing desktop magnetic mounts with different functions, providing users with diverse choices. Some mounts integrate a wireless power bank function. Their mounts can be rotated to adjust the angle and come with a buckle design for convenient storage. At the same time, when the power bank is not in use, it can also serve as a mobile phone mount to meet the needs of video calls or short video viewing. Other mounts focus on portability and multi-scenario applicability. They use a 3M glue base and a double-rotating shaft rod, which can be easily attached to any flat wall to achieve a rich range of angle adjustments, not limited to desktop use. In addition, there are magnetic desktop mobile phone mounts with built-in powerful magnets that support precise alignment and firm attraction of mobile phones.

Detailed implementation manner

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0033] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0034] Embodiment 1:

[0035] Refer to Figures 1-9 , a multi-purpose magnetic attraction bracket with adjustable magnetic force intensity, including an adjusting frame 1, a positioning seat 2 and a base 5 rotatably connected to the adjusting frame 1. A ventilation opening is provided on one side of the positioning seat 2 away from the adjusting frame 1. An anti-slip pad 13 made of rubber is fixedly connected to the bottom of the base 5. It further includes: a magnetic attraction ring 3 arranged in the positioning seat 2, wherein a driving part for magnetically adjusting the magnetic attraction ring 3 is provided on the positioning seat 2. When the adjusting part drives the magnetic attraction ring 3 to move towards the inner part of the cavity of the positioning seat 2, the magnetic attraction of the magnetic attraction ring 3 becomes smaller, and the smaller magnetic attraction is used for adsorbing and fixing the mobile phone; a cooling component 4 arranged on the positioning seat 2, wherein a linkage part for adjusting the angle of the cooling component 4 is provided in the positioning seat 2. When the magnetic attraction ring 3 is magnetically adjusted, the cooling component 4 is adjusted to be vertical, and the vertical cooling component 4 is used for cooling the mobile phone, while the horizontal cooling component 4 cools the tablet computer; an air guide cover 6 fixedly connected to the positioning seat 2, an air vent groove is provided on the air guide cover 6, and an aroma tank 11 is threadedly connected in the air guide cover 6. The aroma tank 11 is filled with solid aroma. Among them, an air inlet part for supplying air to the inside of the cooling component 4 is provided on the air guide cover 6, and an adjusting part for regulating the air inlet part is provided on the positioning seat 2.

[0036] Specifically, when the magnetic attraction ring 3 is driven by the driving part to move inside the cavity of the positioning seat 2, the magnetic force intensity of the positioning seat 2 can be adjusted, so that the positioning seat 2 can adsorb and fix electronic devices of different sizes. At the same time, when the driving part is in use, it can drive the linkage part and the adjusting part to move, not only can adjust the angle of the cooling component 4 to change the cooling range of the positioning seat 2, but also can extract the smell inside the fragrance tank 11 to improve the indoor air quality and create a comfortable and pleasant environment.

[0037] Embodiment Two:

[0038] Refer to Figures 4-6 , which is basically the same as Embodiment One. Preferably, it is a specific implementation scheme for specifically adjusting the magnetic force intensity of the positioning seat 2.

[0039] The driving part includes: a knob 8 rotatably connected inside the positioning seat 2, a lead screw 81 fixedly connected to the knob 8, one end of the lead screw 81 away from the knob 8 is rotatably connected to the inner wall of the positioning seat 2 through a bearing, and a threaded sleeve 82 is threadedly connected to the lead screw 81; a ring seat 84 fixedly connected to the magnetic attraction ring 3, one side of the ring seat 84 away from the magnetic attraction ring 3 is fixedly connected with an L-shaped connecting rod 83, the number of the L-shaped connecting rods 83 is two, and one ends of the two L-shaped connecting rods 83 away from the ring seat 84 are both fixedly connected to the threaded sleeve 82. One side of the ring seat 84 away from the magnetic attraction ring 3 is fixedly connected with four limiting rods 85, and the four limiting rods 85 are all slidably connected inside the positioning seat 2.

[0040] Specifically, when adjusting the magnetic force intensity of the magnetic attraction bracket, the user rotates the knob 8 by 180 degrees. When the knob 8 rotates, it drives the lead screw 81 to rotate. When the lead screw 81 rotates, it drives the threaded sleeve 82 to move. When the threaded sleeve 82 moves, it drives the two L-shaped connecting rods 83 to move. When the two L-shaped connecting rods 83 move, they drive the ring seat 84 and the magnetic attraction ring 3 to move inside the cavity of the positioning seat 2. Due to the position movement of the magnetic attraction ring 3, when the electronic device is placed on the positioning seat 2, the distance from the magnetic attraction ring 3 is relatively far, thereby reducing the magnetic force intensity of the positioning seat 2, which is suitable for adsorbing and fixing small electronic devices such as mobile phones. On the contrary, when the magnetic attraction ring 3 is in the default state, the magnetic force intensity of the positioning seat 2 is relatively high, and it can adsorb and fix large electronic devices such as tablet computers;

[0041] By using the limiting rods 85, the ring seat 84 can be limited, thereby improving the stability of the movement of the ring seat 84.

[0042] Embodiment Three:

[0043] Refer to Figures 1-5 and Figure 7 , which is basically the same as Embodiment One. Preferably, it is a specific implementation scheme for specifically cooling the electronic device.

[0044] The cooling component 4 includes: a housing 41 disposed on the positioning seat 2, with heat dissipation grooves formed on the housing 41. When the centrifugal turbo fan 42 blows air onto the heat dissipation fins 46, heat is discharged from the housing 41 through the heat dissipation grooves. Among them, the centrifugal turbo fan 42 is fixedly installed inside the housing 41; an aluminum alloy heat conduction plate 43, fixedly installed on the housing 41, and a heat conduction pad 44 is fixedly connected to the side of the aluminum alloy heat conduction plate 43 away from the housing 41. Among them, a refrigeration sheet 45 is fixedly connected to the side of the aluminum alloy heat conduction plate 43 away from the heat conduction pad 44, and a heat dissipation fin 46 is fixedly connected to the side of the refrigeration sheet 45 away from the aluminum alloy heat conduction plate 43.

[0045] Specifically, after the electronic device is adsorbed and fixed on the positioning seat 2, the heat generated by the operation of the electronic device will be transmitted to the aluminum alloy heat conduction plate 43 through the heat conduction pad 44. At this time, the user starts the centrifugal turbo fan 42 by using an external control switch. The centrifugal turbo fan 42 blows air onto the surface of the heat dissipation fins 46, which can quickly take away the heat, and the aluminum alloy heat conduction plate 43 and the heat conduction pad 44 are cooled by the refrigeration sheet 45, which can improve the heat dissipation quality and efficiency of the electronic device.

[0046] Embodiment 4:

[0047] Referring to Figures 4-6 and Figure 8 and is basically the same as Embodiment 1. Preferably, it is a specific implementation scheme for adjusting the angle of the cooling component 4.

[0048] The linkage part includes: a transmission rod 9 rotatably connected inside the positioning seat 2, symmetrically arranged along the center line of the positioning seat 2. Among them, one end of each of the two transmission rods 9 is fixedly connected to the housing 41; a first gear 91 fixedly sleeved on one of the transmission rods 9, and a second gear 92 fixedly sleeved on the lead screw 81 is meshed with the first gear 91. Since the number of teeth provided on the surface of the first gear 91 is twice that of the second gear 92, when the second gear 92 rotates 180 degrees, the first gear 91 can only rotate 90 degrees; a first tooth synchronous pulley 93 fixedly sleeved on the other transmission rod 9, and a second tooth synchronous pulley 94 is connected to the first tooth synchronous pulley 93 through a tooth synchronous belt. The second tooth synchronous pulley 94 is fixedly sleeved on the lead screw 81. Since the number of tooth grooves provided on the surface of the first tooth synchronous pulley 93 is twice that of the second tooth synchronous pulley 94, when the second tooth synchronous pulley 94 rotates 180 degrees, the first tooth synchronous pulley 93 can only rotate 90 degrees.

[0049] Specifically, when the lead screw 81 in the driving part drives the second gear 92 and the second toothed synchronous pulley 94 to rotate 180 degrees, the second gear 92 drives the first gear 91 to rotate 90 degrees. When the first gear 91 rotates 90 degrees, it drives one of the transmission rods 9 and the cooling component 4 to rotate 90 degrees. When the second toothed synchronous pulley 94 rotates 180 degrees, it drives the first toothed synchronous pulley 93 to rotate 90 degrees. When the first toothed synchronous pulley 93 rotates 90 degrees, it drives the other transmission rod 9 and the cooling component 4 to rotate 90 degrees, so that both cooling components 4 are vertically downward. After vertically adjusting the cooling component 4, it can centrally cool small electronic devices such as mobile phones. On the contrary, when the cooling component 4 is in the unadjusted state and is horizontal, it can centrally cool large electronic devices such as tablet computers.

[0050] Embodiment Five:

[0051] Refer to Figure 4 、 Figure 5 and Figure 8 and

[0052] The air inlet part includes: a connecting pipe 10 fixedly connected to the air guide cover 6, and the connecting pipe 10 is communicated with the inner cavity of the air guide cover 6; at least two groups of horn covers 101, specifically four groups of horn covers 101, fixedly connected in the positioning seat 2. Since the position of the cooling component 4 can be adjusted, each centrifugal turbine fan 42 requires at least two air inlet ends. One end of the connecting pipe 10 away from the air guide cover 6 is fixedly communicated with the horn cover 101, and a filter net 12 is fixedly connected in the ventilation opening of the positioning seat 2, and the filter net 12 cooperates with the horn cover 101.

[0053] Specifically, when the centrifugal turbine fan 42 in the cooling component 4 rotates, external gas enters the inside of the cooling component 4 through the connecting pipe 10 and the horn cover 101. Since the fragrance tank 11 is installed in the air guide cover 6, when the air inlet end of the connecting pipe 10 sucks air into the inside of the air guide cover 6, the smell inside the fragrance tank 11 can be sucked into the cooling component 4 and then discharged by the cooling component 4. While cooling, it can effectively improve the indoor air quality and create a comfortable and pleasant environment.

[0054] Embodiment Six:

[0055] Refer to Figure 1 、 Figure 3 、 Figure 6 and Figure 8 and

[0056] The adjusting part includes: a third gear 7 rotatably connected to the positioning seat 2, a fourth gear 71 meshed with the third gear 7 and fixedly connected to the transmission rod 9. Since the number of teeth on the surface of the fourth gear 71 is twice that of the third gear 7, when the fourth gear 71 rotates 90 degrees, the third gear 7 rotates 180 degrees. A guide wheel frame 72 fixedly connected to the third gear 7, and a pressure wheel 73 rotatably installed on the guide wheel frame 72. The surface of the pressure wheel 73 abuts against one of the connecting pipes 10. It further includes: at least two sets of clamping plates 74, specifically four sets, provided according to the number of connecting pipes 10, fixedly connected to the positioning seat 2, and the clamping plates 74 are sleeved outside the connecting pipes 10.

[0057] Specifically, when the transmission rod 9 in the linkage part drives the fourth gear 71 to rotate 90 degrees, the fourth gear 71 drives the third gear 7 to rotate 180 degrees. When the third gear 7 rotates 180 degrees, it drives one end of the guide wheel frame 72 to rotate 180 degrees around the axis of the third gear 7. When the guide wheel frame 72 rotates, it drives the pressure wheel 73 to rotate 180 degrees, so that the pressure wheel 73 leaves one of the connecting pipes 10 and presses on the other connecting pipe 10. By squeezing and blocking the connecting pipe 10, it can prevent the connecting pipe 10 for air intake from pumping out the gas inside the other connecting pipe 10 and generating noise.

[0058] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
