Description

Technical Field

[0001] The present invention relates to the technical field of fans, and in particular to a fan chassis and a fan. Background Art

[0002] With the improvement of consumption level, fans have become a necessary household appliance, and people's requirements for them are getting higher and higher.

[0003] Generally, a fan includes a fan chassis and a fan body. The fan body is mounted on the fan chassis and supported by the fan chassis, and the fan body delivers air. Among them, the fan chassis usually adopts an integral design or a half-split design. The integral design will increase the size of the packaging box and increase the transportation cost, while the half-split design reduces the packaging size to a certain extent, but the chassis joints are prone to loosening and deformation, which is easy to weaken the chassis support strength. In particular, when the head of the fan body shakes left and right, the chassis joints are prone to splicing misalignment, affecting the stability of the equipment. Therefore, the traditional fan chassis cannot take into account both transportation costs and stability of use. Summary of the invention

[0043] See also Figure 1 According to some embodiments of the present application, the present application provides a fan, including a fan chassis 100 and a fan body, the fan body is installed on the fan chassis 100, and the fan body is supported by the fan chassis 100. The fan body supplies air through a head, and the head can also shake its head left and right to increase the air supply range.

[0044] See also Figure 1-Figure 5According to some embodiments of the present application, a fan chassis 100 includes a disk body 10, and the disk body 10 includes a first disk body 30 and a second disk body 50 located on both sides of a split line 20, and the first disk body 30 and the second disk body 50 can be matched with each other under the action of an external force. Among them, one of the first disk body 30 and the second disk body 50 occupies a larger area on the disk body 10, and the other of the first disk body 30 and the second disk body 50 occupies a smaller area on the disk body 10, and the one of the first disk body 30 and the second disk body 50 that occupies a larger area on the disk body 10 is used to match with the fan body.

[0045] That is to say, the disk body 10 is split into the first disk body 30 and the second disk body 50 along the splitting line 20, and one of the first disk body 30 and the second disk body 50 has a larger area and the other has a smaller area. In this way, the disk body 10 is split asymmetrically, and then the fan body can be installed on the larger one of the first disk body 30 and the second disk body 50. The force applied when the head of the fan body swings is mainly borne by the larger one, so as to prevent the fan body from transmitting too much force to the splitting line 20 and affecting the assembly strength between the first disk body 30 and the second disk body 50, thereby ensuring the support reliability of the fan disk body 10 and reducing the packaging size and the packaging and transportation costs.

[0046] According to some embodiments of the present application, the first disk body 30 occupies a larger area on the disk body 10, and the second disk body 50 occupies a smaller area on the disk body 10, that is, the first disk body 30 has a larger area, and the second disk body 50 has a smaller area, and the first disk body 30 is used to mate with the fan body.

[0047] In this way, the disk body 10 is split into the first disk body 30 and the second disk body 50 along the splitting line 20, and the first disk body 30 has a larger area and the second disk body 50 has a smaller area. The disk body 10 is split asymmetrically, and then the fan body can be installed on the first disk body 30, and the force of the fan body head swinging is mainly borne by the larger one, so as to prevent the fan body from transmitting too much force to the splitting line 20 and affecting the assembly strength between the first disk body 30 and the second disk body 50, thereby ensuring the support reliability of the fan disk body 10, and at the same time reducing the packaging size and packaging and transportation costs. That is, by splitting the disk body 10 asymmetrically, both packaging and transportation costs and use stability can be taken into account.

[0048] Furthermore, the splitting line 20 includes at least two sections of sub-split lines 20, and there is an angle between at least two sections of sub-split lines 21 in the splitting line 20, so that the splitting line 20 can be constructed into a non-linear shape by setting multiple sub-split lines 21 with angles, and the area of ​​the first disk body 30 can be split larger, so as to increase the area of ​​the first disk body to increase the support stability of the fan chassis. Optionally, there is an angle between the sub-split lines 21 at the head and tail ends of the splitting line 20, or there is an angle between two adjacent sub-split lines 21 in the splitting line, which is not limited.

[0049] According to some embodiments of the present application, the disk body 10 has a geometric center 11, and the sub-splitting line 21 adjacent to the geometric center 11 in the splitting line 20 is constructed to bend toward a side that deviates from the geometric center 11 and is close to the second disk body 50. In this way, the area of ​​the first disk body 30 near the geometric center 11 can be increased, and the area of ​​the central area of ​​the first disk body 30 can be increased, which facilitates the assembly of the fan body on the first disk body 30 and improves the overall stability of the fan chassis 100.

[0050] According to some embodiments of the present application, the head of the fan body swings relative to the disk body 10 in a direction parallel to the circumference of the disk body 10, and the swing range of the head of the fan body is projected toward the disk body 10 and is located on the first disk body 30, so that the fan body will not pass above the splitting line 20 during the swinging of the head, thereby preventing the center of gravity of the fan body from being projected onto the splitting line 20 during the operation of the fan, and preventing the fan body from applying force on the splitting line 20 to affect the reliable connection between the first disk body 30 and the second disk body 50, thereby improving the strength and support stability of the chassis.

[0051] According to some embodiments of the present application, the first disk body 30 includes a central mounting portion 32 and a first outer ring 34 connected to each other, and the second disk body 50 includes a second outer ring 52. The central mounting portion 32 is used to match with the fan body, the first outer ring 34 surrounds a portion of the outer circumference of the central mounting portion 32, and the second outer ring 52 surrounds another portion of the outer circumference of the central mounting portion 32 and matches with the first outer ring 34.

[0052] In this way, the fan body is matched with the central mounting portion 32 on the first disk body 30. The fan body is only mounted on the first disk body 30 and has no assembly relationship with the second disk body 50. It will not cover the split line 20 and directly affect the matching of the first disk body 30 and the second disk body 50. In addition, the first disk body 30 also includes a first outer ring 34, and the second disk body 50 includes a second outer ring 52. The first outer ring 34 and the second outer ring 52 are matched and arranged around the outer periphery of the central mounting portion 32. In this way, the central mounting portion 32 is supported by the first outer ring 34 and the second outer ring 52, so that the overall structure of the chassis is more stable.

[0053] Optionally, the angle between the two opposite ends of the first outer ring 34 along the circumferential direction is greater than 180 degrees, and the angle between the two opposite ends of the second outer ring 52 along the circumferential direction is less than 180 degrees. In this way, the first outer ring 34 has a larger area, and the second outer ring 52 has a smaller area, so that the first disk body 30 has a larger area as a whole.

[0054] Alternatively, the first outer ring 34 and the second outer ring 52 are spliced ​​to form a circular ring surrounding the central mounting portion 32. The chassis formed in this way is circular as a whole, which is convenient for placement.

[0055] According to some embodiments of the present application, the central mounting portion 32 includes a first part 321 and a second part 323 that are connected to each other, the first outer ring 34 is arranged around the outer periphery of the first part 321, the second part 323 protrudes relative to the first outer ring 34, and the second outer ring 52 is arranged around the periphery of the second part 323, and at least a portion of the inner circumferential wall of the second outer ring 52 is abutted against at least a portion of the outer circumferential wall of the second part 323 along the radial limit of the second outer ring 52.

[0056] That is to say, the second portion 323 on the central mounting portion 32 protrudes from the first outer ring 34 and is not surrounded by the first outer ring 34, while the second outer ring 52 just surrounds the outside of the second portion 323, so that the second outer ring 52 and the first outer ring 34 can surround the entire central mounting portion 32 after being matched, and the entire structure of the chassis is relatively balanced. In addition, at least part of the inner circumferential wall of the second outer ring 52 and at least part of the outer circumferential wall of the second portion 323 are in radial limiting contact with each other along the second outer ring 52, so that the second disk body 50 and the first disk body 30 are radially limited and assembled through the cooperation of the second outer ring 52 and the second portion 323.

[0057] Furthermore, a limiting groove 33 is provided at the edge of the second portion 323, and the second disk body 50 further includes a protruding piece 54 provided on the second outer ring 52, the protruding piece 54 is provided on the inner peripheral wall of the second outer ring 52, and the protruding piece 54 is embedded in the limiting groove 33. In this way, the installation position of the second disk body 50 and the first disk body 30 is preliminarily positioned by the cooperation between the protruding piece 54 and the limiting groove 33, so as to facilitate the subsequent matching of the first disk body 30 and the second disk body 50.

[0058] See also Figure 2-Figure 6 According to some embodiments of the present application, the two opposite ends of the first outer ring 34 along its own circumference are both first outer peripheral ends 341, and the two opposite ends of the second outer ring 52 along its own circumference are both second outer peripheral ends 521. The first outer peripheral end 341 and the second peripheral end 521 are mutually limited and abutted and interlocked along the circumference of the first outer ring 34. In this way, the first outer peripheral end 341 and the second peripheral end 521 of the first outer ring 34 and the second outer ring 52 that are connected to each other are interlocked to achieve the matching of the first outer ring 34 and the second outer ring 52.

[0059] Furthermore, a buckle 523 is provided on one of the first peripheral end 341 and the second peripheral end 521, and a buckle position 343 is provided on the other of the first peripheral end 341 and the second peripheral end 521, and the buckle 523 is engaged with the buckle position 343 to match the first peripheral end 341 and the second peripheral end 521 through the cooperation of the buckle 523 and the buckle position 343.

[0060] Optionally, the second peripheral end 521 is provided with a buckle 523, and the first peripheral end 341 is provided with a recessed buckle position 343. During the installation process, the second disk body 50 is sleeved on one side of the first disk body 30, and the buckle 523 of the second peripheral end 521 extends into the buckle position 343 of the first peripheral end 341, thereby realizing the matching of the first disk body 30 and the second disk body 50.

[0061] See also Figure 7-Figure 9 According to some embodiments of the present application, the second portion 323 protrudes relative to the first peripheral end 341, and an angle region 60 is defined between the second portion 323 and the first peripheral end 341. The first disk body 30 further includes a reinforcing portion 70, which is connected to the second portion 323 and extends to the angle region 60. The reinforcing portion 70 connected to the second portion 323 is arranged so that the second portion 323 does not protrude alone, and the reinforcing portion 70 extends into the angle region 60. In this way, when the second portion 323 is subjected to external force, it can be transmitted to the reinforcing portion 70 in the angle region 60. The external force on the second portion 323 is shared by the reinforcing portion 70, thereby improving the strength of the second portion 323 and preventing the second portion 323 from being damaged.

[0062] See also Figure 8-Figure 10 Furthermore, the reinforcing portion 70 is integrally formed with the second portion 323 and connected to the first portion 321, so that the reinforcing portion 70 is integrally formed with the second portion 323, and the reinforcing portion 70 and the second portion 323 are integrated into one, so that the whole formed by the second portion 323 and the reinforcing portion 70 is connected to the first portion 321, and the overall area formed by the integral molding of the second portion 323 and the reinforcing portion 70 is larger, which can support and bear force well, and the overall force is more uniform, which prevents the existence of obvious weak force areas, thereby improving the overall strength of the first disk body 30.

[0063] Furthermore, the reinforcing portion 70 is connected to the first peripheral end 341, so that the reinforcing portion 70 protrudes from the second portion 323 to the angle area 60 and then extends to be connected to the first peripheral end 341, so that the reinforcing portion 70 is connected to and covers the angle area 60 between the second portion 323 and the first peripheral end 341, so that the first peripheral end 341 and the second portion 323 are connected to each other, preventing the first peripheral end 341 and the second portion 323 from being suspended in the air, thereby improving the strength of the first peripheral end 341 and the second portion 323.

[0064] According to some embodiments of the present application, along the thickness direction of the disk body 10, the bottom end of the reinforcing portion 70 is at least connected to the second portion 323, and there is an installation gap 80 between the top end of the reinforcing portion 70 and the second portion 323 and the first peripheral end 341, and the second peripheral end 521 is sleeved on the reinforcing portion 70 and at least partially extends into the installation gap 80. In this way, on the one hand, the bottom end of the reinforcing portion 70 is connected to the first peripheral end 341 and the second portion 323 to connect the first peripheral end 341 and the second portion 323 to enhance the overall strength; on the other hand, there is an installation gap 80 between the top end of the reinforcing portion 70 and the second portion 323 and the first peripheral end 341, and the second peripheral end 521 of the second disk body 50 can be sleeved on the top end of the reinforcing portion 70 and at least partially extend into the installation gap 80, so that the reinforcing portion 70 and the second disk body 50 avoid each other, so that the second peripheral end 521 of the second disk body 50 can still be matched with the first peripheral end 341.

[0065] Specifically, the second outer ring 52 includes a second outer ring 52 body and a side wall arranged around the outer periphery of the second outer ring 52 body, and the side wall of the second outer ring 52 can penetrate into the installation gap 80 to achieve the sleeve assembly of the second outer ring 52 and the reinforcement portion 70. In addition, a buckle 523 is formed at the side wall of the second outer ring 52 body, and when the side wall of the second outer ring 52 penetrates into the installation gap 80, the buckle 523 also extends into the installation gap 80 and is buckled with the buckle position 343 of the first outer peripheral end 341.

[0066] See also Figure 8 and Figure 11-Figure 12 According to some embodiments of the present application, at least one of the outer peripheral wall of the second portion 323 and the inner peripheral wall of the second outer ring 52 is provided with a rib 90 that abuts against the other, so that the rib 90 is squeezed between the second portion 323 and the second outer ring 52, increasing the friction between the second portion 323 and the second outer ring 52, and improving the installation reliability of the two. In addition, at least one of the first outer peripheral end 341 and the second outer peripheral end 521 is provided with a rib 90 that abuts against the other, so that the rib 90 is squeezed between the second portion 323 and the second outer ring 52, increasing the friction between the first outer peripheral end 341 and the second outer peripheral end 521, and improving the installation reliability of the two.

[0067] In this way, when the first plate body 30 and the second plate body 50 are matched, ribs 90 are also provided at the docking position. After the first plate body 30 and the second plate body 50 are matched, the ribs 90 abut between the first plate body 30 and the second plate body 50 to increase the friction between the first plate body 30 and the second plate body 50, thereby improving the installation reliability of the two.

[0068] According to some embodiments of the present application, the fan chassis 100 further includes a fastener, which passes through the protruding piece 54 on the second disk body 50 and the central mounting portion 32 on the first disk body 30 to further fix the first disk body 30 and the second disk body 50 together.

[0069] According to some embodiments of the present application, the present application further provides a fan chassis 100 as described in any of the above embodiments. The fan chassis 100 includes a disk body 10, and the disk body 10 includes a first disk body 30 and a second disk body 50 located on both sides of a split line 20, and the first disk body 30 and the second disk body 50 are matched with each other. Among them, one of the first disk body 30 and the second disk body 50 occupies a larger area on the disk body 10, and the other of the first disk body 30 and the second disk body 50 occupies a smaller area on the disk body 10, and the one of the first disk body 30 and the second disk body 50 that occupies a larger area on the disk body 10 is used to match with the fan body.

[0070] That is, the disk body 10 is split into the first disk body 30 and the second disk body 50 along the splitting line 20, and one of the first disk body 30 and the second disk body 50 has a larger area and the other has a smaller area. In this way, the disk body 10 is split asymmetrically, and then the fan body can be installed on the larger one of the first disk body 30 and the second disk body 50, and the larger one is mainly used to bear the force when the head of the fan body swings, so as to prevent the fan body from transmitting too much force to the splitting line 20 and affecting the assembly strength between the first disk body 30 and the second disk body 50, thereby ensuring the support reliability of the fan disk body 10, and at the same time reducing the packaging size and reducing the packaging and transportation costs. That is, by splitting the disk body 10 asymmetrically, it is possible to take into account both the packaging and transportation costs and the stability of use.
