Description

Technical Field

[0001] The invention relates to the technical field of household appliances, and in particular to an assembled chassis and a fan. Background Art

[0002] Tower fans are popular among consumers for their soft air output. In the actual installation and use process, the height of the tower fan determines the stability of its installation. In order to ensure the stability of the tower fan, designers generally design the chassis of the tower fan to be larger to increase the contact area with the ground, thereby improving its stability.

[0003] However, during transportation, because the area of ​​the chassis is larger than the cross-sectional area of ​​the body in the height direction, the volume of the packaging box has to adapt to the chassis, and the thickness of the chassis is relatively thin, resulting in empty space in the packaging box. In order to reduce shaking during transportation, additional shock-absorbing materials have to be filled in the above-mentioned empty space, which increases the transportation cost.

[0004] In order to solve the above problems, the prior art designs the original whole chassis into multiple sub-chassis that can be spliced ​​together. During transportation, the sub-chassis are separated from each other to reduce the packaging volume. However, the multiple sub-chassis are usually spliced ​​together by buckles, and the structural strength of the buckles is weak. When the tower fan is moved, the buckles and the slots are easily deformed by external forces, resulting in loosening of the spliced ​​chassis, which in turn causes unstable support for the tower fan.

[0005] On the other hand, the existing sub-chassis is mostly an injection molded shell structure. In order to strengthen the structural strength of the sub-chassis, a number of reinforcing ribs are set inside the shell. The chassis of this structure is light in weight. When the tower fan is hit or the placement surface is uneven, it is easy to tip over. Summary of the invention

[0006] Therefore, in order to solve the above-mentioned problems, the present invention provides an assembled chassis and a fan.

[0007] In order to solve the above problems, the present invention provides an assembled chassis including a sub-chassis, which is provided with a receiving groove; a first connecting part, which is provided on the sub-chassis, and a plurality of identical sub-chassis are assembled into one via the first connecting part; a counterweight, which is provided in the receiving groove; and a second connecting part, which is provided on the counterweight, and a plurality of identical counterweights are assembled into one via the second connecting part.

[0008] Furthermore, the main body of the sub-chassis is semicircular, and a rib is formed along the circumferential edge of the main body, and the rib and the main body form the accommodating groove.

[0009] Furthermore, the retaining edge formed at the straight edge of the main body is constructed as a splicing surface, and the two sub-chassis are assembled in a manner that the splicing surfaces are opposite to each other.

[0010] Furthermore, the first connecting portion is arranged on the splicing surface.

[0011] Furthermore, the first connecting portion includes a limiting block and a limiting groove symmetrically arranged at two ends of the splicing surface, and the limiting block is adapted to the limiting groove.

[0012] Furthermore, the limiting block is constructed as a protrusion protruding from the splicing surface, and the limiting groove is constructed as a notch opened at the edge of the splicing surface.

[0013] Furthermore, the first connecting portion further comprises a hook formed on the splicing surface, and a portion of the splicing surface is snapped into a slot of the hook.

[0014] Furthermore, a plurality of protrusions are provided at the locations where the joint surface is engaged with the hook.

[0015] Furthermore, the counterweight is adapted to the receiving groove.

[0016] Furthermore, the second connecting portion is arranged on a connecting surface of the counterweight component close to the splicing surface.

[0017] Furthermore, the second connecting portion includes a lug and a groove symmetrically formed on the connecting surface, and the lug is matched with the groove.

[0018] Furthermore, a first connecting hole is provided on the lug and the groove, and the lug and the groove are locked together through the first connecting hole.

[0019] The assembled chassis in the present invention further comprises second connection holes respectively arranged on the counterweight and the sub-chassis, and the counterweight and the sub-chassis are locked together via the second connection holes.

[0020] The present invention also provides a fan comprising any of the above-mentioned assembled chassis.

[0021] Furthermore, the fan is a tower fan.

[0022] The technical solution of the present invention has the following advantages:

[0023] 1. The assembled chassis in the present invention includes a sub-chassis, which is provided with a receiving groove; a first connecting portion is provided on the sub-chassis, and a plurality of identical sub-chassis are assembled into one through the first connecting portion; a counterweight is provided in the receiving groove; and a second connecting portion is provided on the counterweight, and a plurality of identical counterweights are assembled into one through the second connecting portion.

[0024] Firstly, in the present invention, the whole chassis of the original fan is designed to be a plurality of sub-chassis that can be assembled with each other. In terms of packaging, the sub-chassis are small in size, occupy less packaging space, and are convenient to transport.

[0025] Furthermore, in order to ensure the stability of the chassis as a whole, a counterweight is added to the receiving groove formed in the sub-chassis in the present invention to increase the weight of the entire chassis, thereby improving the stability of the chassis. At the same time, in order to ensure the assembly strength between the sub-chassis, while using the first connection part to connect and fix, the connection strength between the sub-chassis is further strengthened by the counterweight, wherein while the counterweight is fixed in the receiving groove, the counterweights in different receiving grooves are also connected and fixed by the second connection part.

[0026] In addition, it is explained that the sub-chassis and counterweights in the present invention are of the same structure. In the field of fans, the chassis are generally injection-molded structural parts. Injection-molded parts require corresponding molds to cooperate with the processing, and the design and processing costs of the molds are relatively high. The structures of the sub-chassis and counterweights are the same, and the corresponding molds are the same, that is, one set of molds can realize the processing of the sub-chassis or counterweights, eliminating the need to design multiple sets of molds when the sub-chassis or counterweights are different, thereby reducing the processing cost.

[0027] 2. The ribs formed at the straight edges of the main body of the assembled chassis of the present invention are constructed as splicing surfaces, and the two sub-chassis are assembled in a manner that the splicing surfaces face each other. The two sub-chassis are small in number, which can reduce the process steps of assembly and improve the efficiency of assembly. The semi-disc-shaped sub-chassis can be assembled by butting the surfaces where their diameters are located. The assembly method is simple and easy to use, and the efficiency of assembly can also be improved.

[0028] 3. The connection part of the assembled chassis in the present invention includes a limit block and a limit groove respectively arranged at both ends of the sub-chassis in the circumferential direction, and the limit block is adapted to the limit groove. As mentioned above, the sub-chassis is semi-disc-shaped, and the use of the limit block and the limit groove can prevent it from moving and dislocating along the diameter direction of the sub-chassis during splicing.

[0029] 4. The first connection part of the assembled chassis in the present invention also includes a hook formed on the splicing surface, and a portion of the splicing surface is snapped into the slot of the hook. The setting of the hook limits the displacement between the two sub-chassis in the radial direction, and cooperates with the above-mentioned limit block and limit slot to enhance the connection strength between the sub-chassis.

[0030] 5. In the assembled chassis of the present invention, a plurality of protrusions are provided at the joint surface where the hook is connected. The protrusions can increase the friction between the inner side of the hook slot and the joint surface, ensure the interference fit of the joint position, prevent the hook from detaching from the joint surface, and ensure the connection strength between the sub-chassis.

[0031] 6. In the assembled chassis of the present invention, a first connecting hole is provided on the lug and the groove, and the lug and the groove are locked together through the first connecting hole. In addition to the limiting function of the lug and the groove, the present invention further provides a connecting hole, which is directly used to lock the two together, and double fixation is used to strengthen the connection strength between the two counterweights.

[0032] 7. The assembled chassis in the present invention also includes second connecting holes respectively arranged on the counterweight and the sub-chassis. The counterweight and the sub-chassis are locked together through the second connecting holes. The setting of the second connecting holes strengthens the connection strength between the counterweight and the sub-chassis. The better connection strength between the counterweight and the sub-chassis can indirectly ensure the connection strength between the sub-chassis. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] In addition, 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.

[0050] Example 1

[0051] like Figures 1 to 5 As shown, an assembled chassis provided for this embodiment includes a sub-chassis 1, on which a receiving groove 11 is provided; a first connecting portion 3 is provided on the sub-chassis 1, and a plurality of identical sub-chassis 1 are assembled into one via the first connecting portion 3; a counterweight 2 is provided in the receiving groove 11; and a second connecting portion 4 is provided on the counterweight 2, and a plurality of identical counterweights 2 are assembled into one via the second connecting portion 4.

[0052] The assembled chassis in the present embodiment is used for a fan, specifically a chassis of a tower fan. Of course, it can also be used in other technical fields, such as a chassis of a cabinet air conditioner, etc.

[0053] The assembled chassis in this embodiment is made of plastic, which is formed by injection molding.

[0054] First, in this embodiment, the entire chassis of the original fan is designed to be a plurality of sub-chassis 1 that can be assembled with each other. In terms of packaging, the sub-chassis 1 is small in size, occupies less packaging space, and is convenient for transportation.

[0055] Furthermore, in order to ensure the stability of the chassis as a whole, in this embodiment, a counterweight 2 is added to the receiving groove 11 formed in the sub-chassis 1 to increase the weight of the entire chassis, thereby improving the stability of the chassis. At the same time, in order to ensure the assembly strength between the sub-chassis 1, while the first connecting portion 3 is used to connect and fix, the connection strength between the sub-chassis 1 is further strengthened by the counterweight 2, wherein the counterweight 2 is fixed in the receiving groove 11, and the counterweights 2 in different receiving grooves 11 are also connected and fixed by the second connecting portion 4.

[0056] In addition, it is explained that the sub-chassis 1 and the counterweight 2 in the present embodiment are of the same structure. In the field of fans, the chassis are generally injection-molded structural parts. Injection-molded parts need to be processed with corresponding molds to cooperate with the processing, and the design and processing costs of the molds are relatively high. The structures of the sub-chassis 1 and the counterweight 2 are the same, and the corresponding molds are the same, that is, one set of molds can realize the processing of the sub-chassis 1 or the counterweight 2, eliminating the need to design multiple sets of molds when the sub-chassis 1 or the counterweight 2 are different, thereby reducing the processing cost.

[0057] like Figure 5 As shown in FIG. 1 , the main body 12 of the sub-chassis 1 is semicircular, and a rib is formed along the circumferential edge of the main body 12. The rib and the main body 12 form a receiving groove 11, and the outer contour of the counterweight 2 is adapted to the receiving groove 11. Figure 1 As shown in the figure, the counterweight member 2 is basically consistent with the groove wall of the receiving groove 11, and the structural strength of the sub-chassis retaining edge is low. If the gap space between the counterweight member 2 and the groove wall of the receiving groove 11 is too large, it is easy to be dented under the action of external force, affecting its aesthetics. The adaptive design of the counterweight member 2 and the receiving groove 11 can prevent the above problem.

[0058] In this embodiment, a second connection hole 5 is provided on the counterweight 2 and the sub-chassis 1, and the counterweight 2 and the sub-chassis 1 are locked together through the second connection hole 5. Specifically, the second connection hole 5 is processed on the central symmetry line of the sub-chassis 1 and the counterweight 2, and a screw passes through the second connection hole 5 to lock the counterweight 2 and the sub-chassis 1 together, so as to achieve stable fixing of the counterweight 2 on the sub-chassis 1.

[0059] In some other embodiments, the counterweight 2 and the sub-chassis 1 may be fixedly installed by a buckle assembly or by gluing.

[0060] It is further necessary to explain that the sub-chassis 1 can generally be directly used as the outer shell of the tower fan chassis.

[0061] In order to increase the weight of the counterweight 2, the counterweight in this embodiment is made of waste material die-casting, such as waste iron and some injection molding scraps.

[0062] The following is a description of the assembly method of the sub-chassis 1:

[0063] The rib formed at the straight edge of the body 12 is constructed as a splicing surface 13, and the two sub-chassis 1 are assembled in a manner that the splicing surfaces 13 face each other. The two sub-chassis 1 are small in number, which can reduce the process steps of assembly and improve the efficiency of assembly. The semi-disc-shaped sub-chassis 1 can be assembled by butting the surfaces where their diameters are located, which is simple and easy to use in the assembly method and can also improve the efficiency of assembly.

[0064] like Figure 2 and Figure 4 As shown, the first connection portion 3 is directly formed on the joint surface 13 , which is easy to process and is arranged on the joint surface 13 . The two sub-chassis 1 can be directly connected by butting the joint surfaces 13 , thus simplifying assembly.

[0065] In some other embodiments, the number of the sub-chassis 1 may be three, four, etc., and the shape may be a fan-shaped, triangular, etc. structure.

[0066] The first connection portion 3 in this embodiment includes a limit block 31 and a limit groove 32 symmetrically formed at both ends of the splicing surface 13, and the limit block 31 is adapted to the limit groove 32. As mentioned above, the sub-chassis 1 is semi-disc-shaped, and the use of the limit block 31 and the limit groove 32 can prevent the sub-chassis 1 from moving and misaligning along the diameter direction when splicing.

[0067] like Figure 4 As shown, the limiting block 31 is constructed as a convex block protruding from the splicing surface 13, and the limiting groove 32 is constructed as a notch opened at the upper edge of the splicing surface 13. When the sub-chassis 1 is assembled, the convex block overlaps the above-mentioned notch.

[0068] The first connection portion 3 in this embodiment further includes a hook 33 formed on the joint surface 13, and a portion of the joint surface 13 is engaged with a slot of the hook 33. The setting of the hook 33 limits the displacement between the two sub-chassis 1 in the radial direction, and cooperates with the above-mentioned limit block 31 and limit slot 32 to enhance the connection strength between the sub-chassis 1.

[0069] Furthermore, a plurality of protrusions 34 are provided at the joint surface 13 where the hook 33 is engaged. The protrusions 34 in this embodiment are rib structures. The protrusions 34 can increase the friction between the inner side of the groove of the hook 33 and the joint surface 13, thereby ensuring an interference fit at the engaging position and preventing the hook 33 from detaching from the joint surface 13, so as to ensure the connection strength between the sub-chassis 1.

[0070] In some other embodiments, the protrusions 34 may also be convex points or convex block structures formed on the joint surface 13, which can also play a role in increasing the friction force.

[0071] The following is a description of the assembly method of the counterweight 2:

[0072] like Figure 5 As shown in the figure, the second connecting part 4 is formed on the connecting surface 41 of the counterweight 2 near the splicing surface 13. It includes a lug 42 and a groove 43 symmetrically formed on the connecting surface 41, and the lug 42 is adapted to the groove 43. Furthermore, a first connecting hole 44 is processed on the lug 42 and the groove 43, and the lug 42 and the groove 43 are locked together through the first connecting hole 44. The first connecting hole 44 is directly used to lock the two together, and the double fixation is used to strengthen the connection strength between the two counterweights 2.

[0073] During the assembly process, the above-mentioned counterweight 2 is first fixed in the accommodating groove 11 through the second connecting hole 5, and then one of the sub-chassis is rotated 180 degrees to achieve the overlap of the lug 42 in the groove 43, and finally the two counterweights 2 are locked together by screws through the first connecting hole 44.

[0074] Furthermore, six supporting legs 6 are formed at equal intervals on a side of the counterweight 2 close to the ground to support the entire chassis structure.

[0075] The following describes how the sub-chassis 1 in this embodiment achieves the same structure and can be assembled:

[0076] Since the sub-chassis 1 in this embodiment is semicircular, which is a symmetrical structure about the center of the circle, the structural features of the first connecting portion 3 described below are all symmetrically arranged about the symmetry axis of the sub-chassis 1, so that when two sub-chassis 1 are assembled, one sub-chassis 1 can be rotated 180 degrees to be assembled with the other sub-chassis 1.

[0077] The arrangement of the counterweight 2 is similar to that of the sub-chassis 1 and will not be elaborated here.

[0078] Example 2

[0079] This embodiment provides a fan, specifically a tower fan, which uses the assembled chassis structure described in Example 1 and has all the technical advantages of the assembled chassis, which will not be described in detail here.

[0080] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
