The two materials have different structures and need to be manually distinguished after injection molding production. There will also be anti-misoperation phenomena during the general assembly production. The existing chassis uses snap-on splicing or even screw fixation, which on the one hand results in low production efficiency, and on the other hand, it is difficult for customers to disassemble and assemble when using. Summary of the Invention

[0003] The purpose of the present invention is to provide a foldable self-locking chassis and a tower fan to solve the problems in the background art.

Detailed implementation manners

[0027] In order to better understand the purpose, structure and function of the present invention, the following combines the attached Figure 1-7 , to understand the present invention.

[0028] The existing tower fan chassis is also assembled in two parts, with asymmetric left and right structures, and different molds are required for production. If the same mold is used for production, manual sorting is needed. During the general assembly production, it also needs to be distinguished. Customers need to assemble first and then fix with screws; on the other hand, the mutual installation and disassembly are troublesome and the storage takes up a large space.

[0029] A newly designed foldable self-locking chassis includes a first half chassis 1 and a second half chassis 2 that can rotate relative to each other. The first half chassis 1 and the second half chassis 2 are detachably clamped. The relative positions between the first half chassis 1 and the second half chassis 2 adopt a coupling structure, and the coupling structure includes a buckle assembly and a card slot assembly that can rotate after being clamped. After being clamped, the buckle assembly and the card slot assembly can rotate relative to each other. By rotating relative to each other, it thus meets the requirement that the first half chassis 1 and the second half chassis 2 can be folded relative to each other. This foldable chassis structure is assembled from two parts with the same structure. During the injection molding production process, the same mold can be used for production without sorting. During the general assembly, it also does not need to be distinguished. The two identical parts form a chassis after simple assembly, and there is a self-locking structure to prevent the chassis from separating. When not in use, it can be folded and stored, which can not only improve production efficiency, reduce the unqualified rate, but also improve the user experience.

[0030] Among them, the first half chassis 1 and the second half chassis 2 are detachably clamped through a buckle assembly and a slot assembly, and can be rotated after being clamped by the buckle assembly and the slot assembly, so as to fold or unfold the first half chassis 1 and the second half chassis 2. Further, at least one buckle assembly and at least one slot assembly are connected to the opposite surfaces of the first half chassis 1 and the second half chassis 2 that rotate relative to each other. After being clamped by the buckle assembly and the slot assembly, they can be rotated, so as to fold or unfold the first half chassis 1 and the second half chassis 2.

[0031] Preferably, the first half chassis 1 and the second half chassis 2 are of the same semi-circular structure. This foldable chassis structure is preferably assembled from two parts of the same structure. During the injection molding production process, they can be produced in the same mold without sorting, and there is no need to distinguish them during general assembly. The two identical parts form a chassis through simple assembly, and there is a self-locking structure to prevent the chassis from separating. When not in use, the first half chassis 1 and the second half chassis 2 can be rotated and folded for storage. The chassis structure also takes into account the mold structure, and structures such as the chassis, guide posts, and latches are integrated through structural design, enabling one-piece mold release.

[0032] In this embodiment, the chassis material uses ABS material to ensure small dimensional shrinkage, and the cooperation of the buckle assembly and the slot assembly can effectively lock the structure; buckle assemblies and slot assemblies are connected to both the first half chassis 1 and the second half chassis 2. The buckle assembly is connected to the left side of the opposite surface of the first half chassis 1, and the slot assembly is connected to the right side. While on the second half chassis 2, the slot assembly is connected to the left side of the opposite surface, and the buckle assembly is connected to the right side. The first half chassis 1 and the second half chassis 2 can just cooperate, and the first half chassis 1 and the second half chassis 2 can be directly pressed against each other, so that the buckle assembly on the first half chassis 1 and the slot assembly on the second half chassis 2 are detachably clamped corresponding to each other. Among them, the slot assembly on the first half chassis 1 and the buckle assembly on the second half chassis 2 are detachably clamped corresponding to each other.

[0033] Among them, the buckle assembly includes a buckle support block 3a, a buckle clearance structure 4a, and a guide post 5a; and the slot assembly includes a slot support block 3b, a latch 4b, and a guide rail 5b. The central axes of the guide post 5a and the guide rail 5b are both parallel to the rotation opposite surface of the first half chassis 1 and the second half chassis 2. The guide post 5a is elastically pressed into the guide rail 5b, and the guide post 5a rotates in the guide rail 5b, so that the buckle assembly after clamping can rotate relative to the slot assembly.

[0034] The snap support block 3a is connected to the opposite faces of the first half chassis 1 and the second half chassis 2, and the guide post 5a is connected to the snap support block 3a; the slot support block 3b is connected to the opposite faces of the first half chassis 1 and the second half chassis 2, and the guide rail 5b is provided on the slot support block 3b. A snap clearance structure 4a is provided on the side surface of the snap support block 3a; that is, the position of the guide post 5a needs to be designed with the snap clearance structure 4a to prevent the snap component from interfering with the structure and affecting assembly and folding; a latch 4b is connected to the head of the slot support block 3b, and the guide rail 5b is a strip-shaped guide rail. Further, the latch 4b is an elastic structure, and the latch 4b slides into the snap clearance structure 4a by extrusion. Or the latch 4b is a wedge-shaped structure, and the snap clearance structure 4a is an arc surface, so that the latch 4b slides into the snap clearance structure 4a.

[0035] The operation process of this design in use:

[0036] 1. When the first half chassis 1 and the second half chassis 2 are brought close to each other and buckled, the guide post 5a is inserted into the guide rail 5b.

[0037] 2. The first half chassis 1 and the second half chassis 2 are squeezed against each other and spread out, and the latch 4b on the slot component just slides into the snap clearance structure 4a of the snap component, thereby completing self-locking.

[0038] 3. When the first half chassis 1 and the second half chassis 2 are folded against each other, the latch 4b just turns out of the snap clearance structure 4a and disengages.

[0039] The foldable self-locking chassis of this design is used on an existing tower fan, replacing the tower fan chassis, and a tower fan is designed to facilitate the retraction and use of the tower fan.

[0040] In order to position the body of the tower fan, a main body positioning hole 4 is provided on any one or both of the first half chassis 1 and the second half chassis 2. The main body positioning hole 4 is positioned and connected to the tower fan body. The main body positioning hole 4 is designed and adjusted according to the body structure of the fuselage. After adjustment, it is ensured that the two chassis structures are the same, and integral mold release can be achieved.

[0041] A plurality of support columns 3 are connected to any one or both of the first half chassis 1 and the second half chassis 2. The support columns 3 at the bottom of the first half chassis 1 and the bottom of the second half chassis 2 are designed as an asymmetric structure to ensure that the support columns 3 do not interfere with each other when the chassis is folded.

[0042] An electrical appliance is proposed, including the foldable self-locking chassis described above. The foldable self-locking chassis of this design is not limited to being used on the tower fan proposed in this embodiment, and can also be used on the chassis of other electrical appliances, and the above technical effects can be achieved.

[0043] The production method of the foldable self-locking chassis of this design:

[0044] 1. The injection mold is designed as a unit part according to its structure;

[0045] 2. After injection molding, the parts are packaged uniformly and then put on the production line;

[0046] 3. In the packaging section of the general assembly production line, the chassis can be directly placed into the packing box, or can be placed after assembly. Whether to fold it depends on the requirements of the packing box design;

[0047] 4. During assembly, first take two chassis, namely the first half chassis 1 and the second half chassis 2. Snap the guide post 5a into the guide rail 5b, and push the chassis parallelly until the snap component and the slot component are locked with each other to complete the assembly. When folding is required, manually loosen the snap, pull the chassis apart and then fold it.
