Description

Technical Field

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

[0002] Fans are household appliances used for cooling and increasing indoor air circulation. They have the advantages of low price and ease of use. As people have increasingly stringent requirements for indoor environments, fans are also constantly improving. Among them, circulation fans are gaining more and more market share due to their large air volume and long air supply distance. However, in existing fan structures, the bracket is generally first aligned with the corresponding components, and then fixed and installed by screws or bolts passing through the holes. At least two installation steps are required, which increases manufacturing and installation costs. At the same time, after installation, the nuts or holes will be exposed, resulting in poor integrity of the fan. Summary of the invention

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0034] like Figures 1 to 3 As shown, an embodiment discloses a bracket assembly structure, including a first bracket split 100, a second bracket split 200 and a third bracket split 300, the second bracket split 200 is provided with a first clamping portion 201 and a second clamping portion, the first clamping portion 201 is clamped with the first bracket split 100, a third clamping portion 301 is provided on a first end of the third bracket split 300, a fourth clamping portion 302 is provided on a second end of the third bracket split 300, the third clamping portion 301 is clamped with the first bracket split 100, the third clamping portion 301 and the first clamping portion 201 are respectively provided on both sides of the first bracket split 100, and the fourth clamping portion 302 is clamped with the second clamping portion, wherein one of the first bracket split 100, the second bracket split 200 and the third bracket split 300 is provided with a mounting portion 10 for mounting a machine head.

[0035] The above-mentioned bracket assembly structure can be used to install the machine head by utilizing the structure after the first bracket split 100, the second bracket split 200 and the third bracket split 300 are assembled. Since the first clamping portion 201 on the second bracket split 200 and the third clamping portion 301 on the third bracket split 300 are both clamped with the first bracket split 100, the third clamping portion 301 and the first clamping portion 201 are respectively arranged on both sides of the first bracket split 100, and the fourth clamping portion 302 is clamped with the second clamping portion, and the third clamping portion 301 and the fourth clamping portion 302 are respectively located at both ends of the third bracket split 300, that is, one end of the second bracket split 200 and the third bracket split 300 are respectively clamped with both sides of the first bracket split 100, and the other end of the second bracket split 200 and the third bracket split 300 are respectively clamped with the two sides of the first bracket split 100, The three bracket parts are mutually clamped and are not easy to separate. When bearing loads, the three brackets can cooperate in force. When the second bracket part 200 is subjected to force, a torque relative to the first bracket part 100 may be generated. However, since the third bracket part 300 is clamped with the first bracket part 100 and the second bracket part 200 at the same time, the force and torque of the second bracket part 200 can be offset. When the first bracket part 100 and the third bracket part 300 are subjected to force, they can also be jointly borne by other bracket parts, so that the assembled structure has good stability and plays a role in stabilizing the support of the machine head. Since the assembly is completed by clamping, there is no need to set additional screws or bolts for fixing, the assembly is simpler, and the manufacturing and assembly costs can be reduced. After the assembly is completed, the overall appearance has no holes or protruding nuts, etc., and the integrity is better.

[0036] The above “the third clamping portion 301 and the fourth clamping portion 302 are respectively located at two ends of the third bracket split 300” actually refers to the two ends of the third bracket split 300 in its length direction, wherein the length direction of the third bracket split 300 is as follows: Figure 3 As shown in direction a, the third bracket body 300 can be divided into two areas, and the two areas are arranged in sequence along the length direction of the third bracket body 300. The third clamping portion 301 is arranged in one of the areas, and the fourth clamping portion 302 is arranged in the other area. The two areas do not overlap, and the lengths of the two areas can be the same or different.

[0037] Specifically, Figure 1 and Figure 3 As shown, the third clamping portion 301 is located at the end of the third bracket body 300 close to the first bracket body 100 , so that the end of the third bracket body 300 is clamped with the first bracket body 100 .

[0038] Specifically, “snapping” actually means that two of the first bracket part 100 , the second bracket part 200 and the third bracket part 300 will not separate after assembly.

[0039] In one embodiment, if Figures 1 to 3As shown, the second bracket body 200 is also provided with a fifth clamping portion 202, and the third bracket body 300 is provided with a sixth clamping portion 303 corresponding to the fifth clamping portion 202. There are multiple fifth clamping portions 202, and the fifth clamping portion 202 is clamped with the sixth clamping portion 303. At least one fifth clamping portion 202 is provided on the first end and the second end. The clamping cooperation of the fifth clamping portion 202 and the sixth clamping portion 303 achieves the effect that both ends of the second bracket body 200 are clamped with the third bracket body 300, so that the first end of the second bracket body 200 and the third bracket body 300 can clamp the first bracket body 100, and can further strengthen the connection between the second bracket body 200 and the third bracket body 300, so that the overall structure after assembly is more stable, the bearing capacity is improved, and the structural damage is not easy to occur, and stable support for the head can be provided.

[0040] In one embodiment, if Figure 1 and Figure 3 As shown, the two fifth clamping parts 202 are respectively arranged on both sides of the third clamping part 301. At this time, the connection between the second bracket part 200 and the third bracket part 300 is more stable, and the clamping effect on the first bracket part 100 is better.

[0041] Specifically, the two fifth clamping portions 202 are located at two sides of the third clamping portion 301 along the length direction of the third bracket body 300 .

[0042] Specifically, the line between the positions of the two fifth clamping portions 202 is perpendicular or approximately perpendicular to the length direction of the third bracket body 300 .

[0043] In one embodiment, if Figure 1 and Figure 3 As shown, both sides of the third bracket body 300 are bent toward the same side to form an assembly flange 310, and the fifth clamping portion 202 is arranged on the assembly flange 310. When the third clamping portion 301 is clamped with the first bracket body 100, the first bracket body 100 is partially located between the two assembly flanges 310. The assembly flange 310 can facilitate the clamping of the fifth clamping portion 202 and the sixth clamping portion 303, and can also enhance the structural strength of the third bracket body 300, and has better bending resistance. During assembly, the first bracket body 100 is partially located between the two assembly flanges 310, and the assembly flange 310 can limit the first bracket body 100, facilitate assembly, and improve the stability after assembly. In addition, after assembly, the assembly flange 310 will cover the first bracket body, which can reduce the number of assembly seams and improve the integrity of the appearance.

[0044] In one embodiment, if Figure 1 and Figure 2As shown, the second bracket body 200 is provided with a reinforcing rib 210, which is located between two assembly flanges 310. The reinforcing rib 210 can increase the structural strength of the second bracket body 200 and improve its bending resistance. At the same time, the reinforcing rib 210 cooperates with the assembly flange 310 to limit each other and increase the stability after assembly.

[0045] In one embodiment, if Figure 1 , Figure 4 and Figure 5 As shown, two seventh clamping parts 101 are provided on the first bracket body 100, and the seventh clamping parts 101 are clamped with the first clamping parts 201. The two seventh clamping parts 101 are arranged at intervals, and the reinforcing ribs 210 can extend between the two seventh clamping parts 101. At this time, the clamping cooperation between the first bracket body 100 and the first clamping part 201 can be facilitated, and the reinforcing ribs 210 and the first bracket body 100 can also limit each other, thereby improving the structural stability after assembly.

[0046] Alternatively, if Figure 3 and Figure 4 As shown, the first bracket body 100 is further provided with an eighth clamping portion 102 clamped with the third clamping portion 301 .

[0047] Specifically, when the first bracket body 100 and the third bracket body 300 are assembled, the two seventh clamping parts 101 are located between the two assembly flanges 310, ensuring that the assembly flanges 310 can wrap the first bracket body 100 with the second bracket body 200, and the fifth clamping part 202 can be clamped with the sixth clamping part 303.

[0048] In one embodiment, if Figure 3 As shown, in the length direction of the third bracket body 300, at least one fourth clamping portion 302 is provided between two adjacent sixth clamping portions 303. Through the above arrangement, the tightness of the connection between the second bracket body 200 and the third bracket body 300 can be increased, and the stability and strength of the structure can be improved.

[0049] In one embodiment, if Figure 1 and Figure 4 As shown, the first clamping part 201 is plugged with the first bracket body 100, the second clamping part is plugged with the fourth clamping part 302, the third clamping part 301 is plugged with the first bracket body 100, and the fifth clamping part 202 is plugged with the sixth clamping part 303. Through plug-in cooperation, fixation can be achieved and assembly is simple.

[0050] Specifically, the above-mentioned "plug-in" is an interference fit to ensure that it is not easy to come off.

[0051] Specifically, the first clamping portion 201 , the second clamping portion 202 , and the fifth clamping portion 202 are all grooves.

[0052] In other embodiments, the "clamping" may also be in other forms, such as the clamping cooperation between the second clamping portion and the fourth clamping portion 302, the second clamping portion is a first hook, the fourth clamping portion 302 is a second hook, the first hook and the second hook are both inverted "J" shaped structures, when the second bracket split 200 and the third bracket split 300 are close, the first hook and the second hook end contact and then elastic deformation occurs, when the first hook and the second hook move to a position where they are no longer in contact, the first hook and the second hook are restored in shape, at this time if the second bracket split 200 and the third bracket split 300 are close The three bracket splits 300 have a tendency to separate from each other, and the first hook and the second hook will hook together, and a clamping effect can also be achieved. Considering that when the first hook and the second hook are hooked together, the first hook or the second hook will have a certain movable stroke, a buffer is set on the outer edge of the first hook. When the first hook approaches the third bracket split 300, the buffer will be compressed until the first hook and the second hook are hooked together. At this time, the buffer will recover, so that the first hook is hooked tightly with the second hook, thereby preventing the second bracket split 200 and the third bracket split 300 from relative displacement.

[0053] In one embodiment, if Figures 1 to 3 As shown, the second bracket split 200 includes a first frame 220 and a second frame 230, the first frame 220 is connected to one end of the second frame 230, and the other ends of the first frame 220 and the second frame 230 are spaced apart, and mounting portions 10 are provided on opposite sides of the first frame 220 and the second frame 230, the first frame 220 and the second frame 230 are spaced apart, and the first frame 220 and the second frame 230 are both provided with a first clamping portion 201 and a second clamping portion, the first bracket split 100 includes a first connecting body 120 and a second connecting body 130, and the third bracket split 300 is two, the first connecting body 120 is respectively clamped with the first clamping portion 201 on the first frame 220 and the third clamping portion 301 on one of the third bracket splits 300, and the second connecting body 130 is respectively clamped with the first clamping portion 201 on the second frame 230 and the third clamping portion 301 on the other third bracket split 300. At this time, the machine head can be installed and fixed by the first frame 220 and the second frame 230 respectively, so that the support of the machine head is more stable and the overall force is more uniform, which is conducive to improving the stability during operation.

[0054] In one embodiment, if Figures 1 to 4As shown, the first bracket split body 100 further includes a main body 140, which is connected to the first connecting body 120 and the second connecting body 130 respectively, and the first connecting body 120 and the second connecting body 130 are respectively located on both sides of the main body 140, and the second bracket split body 200 further includes an intermediate body 240, which is connected to the first frame body 220 and the second frame body 230 respectively, and the first frame body 220 and the second frame body 230 are located on both sides of the intermediate body 240, and one of the intermediate body 240 and the main body 140 is provided with an assembly groove 141, and the other is plugged into the assembly groove 141. Through the plug-in cooperation between the intermediate body 240 and the main body 140, the assembly of the first bracket split body 100 and the second bracket split body 200 can be facilitated, and the stability of the overall structure after assembly can be ensured.

[0055] In one embodiment, if Figure 2 and Figure 4 As shown, the assembly groove 141 is provided on the main body 140, the intermediate body 240 is plugged into the assembly groove 141, a first matching portion 142 is provided on the side wall of the assembly groove 141, a second matching portion 241 is provided on the outer wall of the intermediate body 240, and the first matching portion 142 is limitedly matched with the second matching portion 241. The limited matching of the first matching portion 142 and the second matching portion 241 can prevent the intermediate body 240 from being separated from the assembly groove 141.

[0056] Optionally, the first matching portion 142 is a notch, and the second matching portion 241 is a buckle body, and the buckle body can slide into the notch to achieve limited matching between the first matching portion 142 and the second matching portion 241 .

[0057] In one embodiment, if Figure 1 As shown, the first frame 220 and the second frame 230 are both arc-shaped structures. At this time, the shapes of the first frame 220 and the second frame 230 can better match the head, providing a larger rotation angle range for the head.

[0058] An embodiment discloses a fan, comprising any one of the bracket assembly structures described above.

[0059] The fan can be used to install the head of the machine using the structure after the first bracket split 100, the second bracket split 200 and the third bracket split 300 are assembled. Since the first clamping portion 201 on the second bracket split 200 and the third clamping portion 301 on the third bracket split 300 are clamped with the first bracket split 100, the third clamping portion 301 and the first clamping portion 201 are respectively arranged on both sides of the first bracket split 100, the fourth clamping portion 302 is clamped with the second clamping portion, and the third clamping portion 301 and the fourth clamping portion 302 are respectively located at both ends of the third bracket split 300, that is, one end of the second bracket split 200 and the third bracket split 300 are respectively clamped with the two sides of the first bracket split 100, and the other end of the second bracket split 200 and the third bracket split 300 are mutually clamped. The three bracket parts are snap-fitted to each other and are not easy to separate. When bearing loads, the three brackets can cooperate in force. When the second bracket part 200 is subjected to force, a torque relative to the first bracket part 100 may be generated. However, since the third bracket part 300 is snap-fitted to the first bracket part 100 and the second bracket part 200 at the same time, the force and torque of the second bracket part 200 can be offset. When the first bracket part 100 and the third bracket part 300 are subjected to force, the other bracket parts can also bear the load together, so that the assembled structure has good stability and plays a role in stabilizing the support of the machine head. Since the assembly is completed by snap-fitting, there is no need to set additional screws or bolts for fixing, so the assembly is simpler, which can reduce the manufacturing and assembly costs, and after the assembly is completed, the overall appearance has no holes or protruding nuts, etc., and the integrity is better.
