Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, in particular to a spliced bottom plate and a fan. BACKGROUND

[0002] Tower fans are favored by consumers due to their soft air outlet characteristics. In actual installation and use, the height of the tower fan body determines the stability of the installation, and in order to ensure the stability of the tower fan, the designer generally designs a larger bottom plate to increase the contact area with the ground, thereby improving the stability.

[0003] However, during transportation, because the area of the bottom plate is larger than the cross-sectional area of the height of the body, the volume of the packaging box needs to be adapted to the bottom plate, and the thickness of the bottom plate is relatively thin, resulting in a spare space in the packaging box. In order to reduce the shaking during transportation, additional damping materials need to be filled in the above-mentioned spare space, increasing the transportation cost.

[0004] In order to solve the above problems, the original whole bottom plate is designed into multiple splicable sub-bottom plates, and the sub-bottom plates are separated from each other during transportation, reducing the packaging volume. However, the splicing part of the multiple sub-bottom plates is usually buckled and connected together, and the structure strength of the buckling part is weak. When the tower fan moves, the buckling and the groove are easily deformed under external force, causing the splicing part of the splicing type bottom plate to loosen, and further causing unstable support to the tower fan. SUMMARY

[0005] Therefore, in order to solve the above problems, the present application provides a splicing type bottom plate and a fan.

[0006] In order to solve the above problems, the present application provides a splicing type bottom plate including a sub-bottom plate; a first connecting part provided on the sub-bottom plate, and a plurality of identical sub-bottom plates spliced into one through the first connecting part; and a second connecting part provided on the sub-bottom plate, and connected between the sub-bottom plate and the first connecting part.

[0007] Further, the sub-bottom plate is in the shape of a semicircular disc, has a splicing surface, and two sub-bottom plates are spliced into a circular disc in a manner that the splicing surfaces face each other.

[0008] Further, the first connecting part is provided on the splicing surface.

[0009] Further, the splicing surface is provided with an empty slot corresponding to the first connecting part.

[0010] Further, the first connecting part includes a clasp and a clamping groove symmetrically provided at both ends of the splicing surface, and the clasp is matched with the clamping groove.

[0011] Further, the clamping hook is arranged protruding from the joint surface, and the clamping slot is arranged as a notch on the edge of the joint surface.

[0012] Further, the first connecting part further comprises a T-shaped clamping head and a T-shaped clamping slot symmetrically formed on the joint surface.

[0013] Further, the second connecting part is arranged on the joint surface and close to the T-shaped clamping slot.

[0014] Further, the second connecting part is a buckle, which has a connecting arm arranged on the joint surface and a clamping head formed on the connecting arm, and the clamping head is used to be clamped on the T-shaped clamping head.

[0015] The application further provides a fan comprising the jointed chassis.

[0016] Further, the fan is a tower fan.

[0017] The application has the following advantages:

[0018] 1. The jointed chassis comprises a sub-chassis, a first connecting part arranged on the sub-chassis, a plurality of identical sub-chassis assembled into one through the first connecting part, and a second connecting part arranged on the sub-chassis and connected between the sub-chassis and the first connecting part.

[0019] Firstly, the whole chassis in the original fan is designed as a plurality of sub-chassis which can be assembled with each other in the application, and the volume of the sub-chassis is small, the packaging space is small, and the transportation is convenient. Further, each sub-chassis has the same structure in the application, and the chassis in the fan field is generally an injection molding structure, which needs to be designed with a corresponding mold for processing. The design and processing cost of the mold is high, the structure of each sub-chassis is the same, the corresponding mold is the same, that is, a set of mold can realize the processing of the sub-chassis, which avoids the need to design multiple sets of molds when the sub-chassis is different, and reduces the processing cost.

[0020] Further, in order to ensure the connection strength between the sub-chassis, the first connecting part is used between the sub-chassis, and the second connecting part is further arranged, one end of the second connecting part acts on the sub-chassis, and the other end further acts on the first connecting part, so that the first connecting part realizes the secondary connection and fixation with the sub-chassis, thereby ensuring the stability and reliability of the connection and fixation between the sub-chassis.

[0021] 2. In the modular chassis of this invention, the sub-chassis is semi-circular in shape and has a splicing surface. Two sub-chassis are assembled into a circular shape with their splicing surfaces facing each other. The two sub-chassis are few in number, reducing the number of assembly steps and improving assembly efficiency. Furthermore, the semi-circular sub-chassis can be assembled by aligning their diameter surfaces, making the assembly method simple and easy to learn, further improving assembly efficiency.

[0022] 3. In the modular chassis of the present invention, the first connecting part includes hooks and slots symmetrically arranged at both ends of the splicing surface, wherein the hooks and slots are adapted to each other. As mentioned above, the sub-chassis is semi-circular in shape, and the use of limiting blocks and limiting slots during splicing can prevent it from moving or misaligning radially along the sub-chassis.

[0023] 4. In the modular chassis of the present invention, the first connecting part further includes a T-shaped clip head and a T-shaped clip groove symmetrically formed on the splicing surface. The T-shaped clip head is engaged in the T-shaped clip groove, which can further enhance the connection strength between the sub-chassis.

[0024] 5. In the modular chassis of the present invention, the second connecting part is a buckle. The buckle has a connecting arm disposed on the splicing surface and a clip head formed on the connecting arm. The clip head is used to snap onto the T-shaped clip head. The second connecting part realizes a further fixing effect on the T-shaped clip head in the first connecting part and enhances the connection strength between the T-shaped clip head and the sub-chassis.

[0035] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0038] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0039] Example 1

[0040] like Figs. 1 to 3 As shown, the modular chassis provided in this embodiment includes a sub-chassis 1; a first connecting part 2, disposed on the sub-chassis 1, wherein several identical sub-chassis 1 are assembled into one unit via the first connecting part 2; and a second connecting part 3, disposed on the sub-chassis 1, wherein the second connecting part 3 connects the sub-chassis 1 and the first connecting part 2.

[0041] The modular chassis used in this embodiment is for a fan, specifically a tower fan chassis. Of course, it can also be used in other technical fields, such as the chassis of a cabinet air conditioner.

[0042] The modular chassis in this embodiment is made of plastic and is formed by injection molding.

[0043] In this embodiment, the original fan's single chassis is designed as multiple assembleable sub-chassis 1. In terms of packaging, the sub-chassis 1 is small in size, occupies less packaging space, and is convenient for transportation. Furthermore, each sub-chassis 1 in this embodiment has the same structure. Generally, injection-molded parts require corresponding molds for processing, and mold design and processing costs are high. Since each sub-chassis 1 has the same structure, the corresponding mold is the same; that is, one set of molds can be used to process each sub-chassis 1, eliminating the need to design multiple sets of molds when the sub-chassis 1 are different, thus reducing processing costs.

[0044] Furthermore, in this embodiment, in order to ensure the connection strength between the sub-chassis 1, a second connection 3 is also provided in addition to the first connection part 2 between the sub-chassis 1. One end of the second connection part 3 acts on the sub-chassis 1, and the other end further acts on the first connection part 2, so that the first connection part 2 achieves secondary connection and fixation with the sub-chassis 1, thereby ensuring the stability and reliability of the connection and fixation between each sub-chassis 1.

[0045] like Fig. 1 In the example, there are two sub-base plates 1, and each sub-base plate 1 is semi-circular in shape. The two sub-base plates 1 are symmetrically assembled about their splicing surface 11. The number of sub-base plates 1 is small, which reduces the assembly process steps and improves assembly efficiency. In addition, the semi-circular sub-base plates 1 can be assembled by aligning their diameter faces, which is simple and easy to use, and also improves assembly efficiency.

[0046] In some other embodiments, the number of the sub-chassis 1 may be three or four, and its shape may be a fan-shaped, triangular, or other structure.

[0047] The following is a detailed explanation of how the sub-chassis 1 is connected via the first connecting part 2:

[0048] like Fig. 3 As shown, the first connecting part 2 is formed on the splicing surface 11. While its processing is simple, it is set on the splicing surface 11, and the two sub-chassis 1 can be directly connected during the process of docking the splicing surface 11, which simplifies the assembly.

[0049] In order to reserve connection space for the first connecting part 2, the splicing surface 11 is machined with a clearance groove 4 corresponding to the first connecting part 2, and the clearance groove 4 has a square structure.

[0050] likeFig. 3 As shown, the first connecting part 2 includes hooks 21 and slots 22 symmetrically formed at both ends of the splicing surface 11. The hooks 21 and slots 22 are adapted to each other. During installation, the hooks 21 are engaged with the slots 22.

[0051] Furthermore, the hook 21 is constructed as a hook structure protruding from the splicing surface 11, and the slot 22 is constructed as a notch opened at the upper edge of the splicing surface 11. The hook 21 is hung at the notch, wherein the part of the splicing surface 11 located at the notch extends into the hook slot of the hook, and the two are connected by an interference fit.

[0052] like Fig. 3 As shown in the diagram, the first connecting part 2 also includes a T-shaped clip 23 and a T-shaped slot 24 symmetrically formed on the splicing surface 11. When the two sub-chassis 1 are assembled, the T-shaped clip 23 of one is engaged in the T-shaped slot 24 of the other.

[0053] The structure of the second connecting part 3 will be described below:

[0054] like Fig. 2 As shown, the second connecting part 3 is disposed on the splicing surface 11 and near the T-shaped slot 24. The second connecting part 3 is a buckle, which has a connecting arm 31 formed on the splicing surface 11 and a locking head 32 formed on the connecting arm 31. The locking head 32 is used to engage with the T-shaped locking head 23. The second connecting part 3 further fixes the T-shaped locking head 23 in the first connecting part 2, enhancing the connection strength between the T-shaped locking head 23 and the sub-chassis 1.

[0055] The following explains how the sub-chassis 1 in this embodiment achieves the same structure and can be assembled:

[0056] Since the sub-chassis 1 in this embodiment is semi-circular and is a symmetrical structure about the center, the structural features of the first connecting part 2 and the second connecting part 3 described below are symmetrically arranged about the axis of symmetry of the sub-chassis 1, so that when the two sub-chassis 1 are assembled, one sub-chassis 1 can be rotated 180 degrees to be assembled with the other sub-chassis 1.

[0057] like Fig. 1 As shown, in this embodiment, three support legs 5 are also provided at the circumferential edge of the sub-chassis 1 to achieve stable support for the entire chassis.

[0058] Example 2

[0059] This embodiment provides a fan, specifically a tower fan, which has all the technical advantages of a modular chassis, and will not be elaborated here.

[0060] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
