DETAILED DESCRIPTION

[0032] In order to make the objects, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, any other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of the present application.

[0033] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplicity, the elements and settings of particular examples in the following are described. Of course, they are only examples and are not intended to limit the present application. Furthermore, the present application can repeat the reference numerals and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not indicate the relationship between the discussed various embodiments and / or settings.

[0034] In order to facilitate the description, spatial relative terms can be used in the description to describe the relative position relationship or movement condition of one element or feature with respect to another element or feature as shown in the drawings, such as "inner", "outer", "inboard", "outboard", "under", "below", "on", "above", "front", "back", and the like. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawings is flipped over or the posture is changed or the movement state is changed, then the directional indications are also changed accordingly, for example: the element described as "under" or "below" another element or feature will be oriented as "above" or "above" another element or feature. Therefore, the example term "below" can include both the up and down positions. The device can be additionally oriented (rotated by 90 degrees or in other directions) and the spatial relative relationship descriptors used in the description are interpreted accordingly.

[0035] In order to solve the technical problem in the prior art that the connection line such as the power line needs to be arranged outside the support pipe due to the inability of the terminal to adapt to rotation inside the support pipe, thereby affecting the appearance and safety, the application provides a support pipe wiring structure and a fan, which can realize 360° relative free rotation between the support pipe, the rotating outer pipe assembly and the rotating inner pipe assembly, and the rotating outer pipe assembly and the rotating inner pipe assembly can also relatively rotate freely by 360°. During rotation, the connection terminal and the copper pipe are always in contact, thereby realizing a stable electrical connection state. By adopting the scheme provided by the application, the terminal of the head assembly of the fan and the terminal of the foot disc assembly can both remain in a fixed state, the internal hiding type design of the connection line of the fan is met, and the overall appearance and safety are improved under the premise of ensuring the normal operation of the fan.

[0036] In the first aspect, referring to Figure 1 , the application provides a support pipe 12 wiring structure which can be rotationally arranged inside the support pipe 12 and comprises a rotating outer pipe assembly 2 and a rotating inner pipe assembly 3 which are nested with each other. The rotating outer pipe assembly 2 comprises a rotating outer pipe 21 and a plurality of connection terminals 22 arranged on the inner wall of the front end of the rotating outer pipe 21. The rotating inner pipe assembly 3 comprises a rotating inner pipe 31 and a plurality of copper pipes 32 which are sleeved on the rear end of the rotating inner pipe 31. The rear end of the rotating inner pipe 31 is embedded in the front end of the rotating outer pipe 21, and the connection terminals 22 and the copper pipes 32 correspond to each other and are electrically connected.

[0037] In the embodiments provided by the application, the number of the connection terminals 22 and the copper pipes 32 is 4 groups. When the rear end of the rotating inner pipe 31 is inserted into the front end of the rotating outer pipe 21, the four groups of copper pipes 32 on the rotating inner pipe 31 correspond to the four groups of connection terminals 22 on the front end of the rotating outer pipe 21 one by one, and are electrically connected through the contact between the connection terminals 22 and the copper pipes 32, thereby satisfying the electrical connection between the rotating outer pipe assembly 2 and the rotating inner pipe assembly 3. When the support pipe 12 rotates, it can rotate freely by 360° relative to the rotating outer pipe assembly 2 and the rotating inner pipe assembly 3, and will not affect or twist the electrical connection state between the rotating outer pipe assembly 2 and the rotating inner pipe assembly 3. When the rotating outer pipe assembly 2 and the rotating inner pipe assembly 3 rotate freely by 360°, the copper pipes 32 provide a 360° contact surface, so that when the rotating outer pipe 21 and the rotating inner pipe 31 rotate relative to each other to any angle, the contact between the connection terminals 22 and the corresponding copper pipes 32 can be ensured, thereby avoiding abnormal situations such as disconnection between the connection terminals 22 and the copper pipes 32 due to the influence of rotation.

[0038] In some embodiments, referring to Figure 2 , Figure 3The inner wall of the rotating outer tube 21 is provided with a plurality of clamping grooves 211 corresponding to the connecting terminals 22, and the connecting terminals 22 are embedded in the clamping grooves 211. By providing the clamping grooves 211 on the inner wall of the rotating outer tube 21, the connecting terminals 22 are fixed and limited by the clamping grooves 211. In this way, the positions of the connecting terminals 22 on the rotating outer tube 21 can be fixed during the assembly process and the relative rotation between the rotating outer tube 21 and the rotating inner tube 31, thereby ensuring the stable contact state between the connecting terminals 22 and the copper pipes 32.

[0039] In some embodiments, referring to Figure 4 , Figure 5 The rotating inner tube 31 is provided with a plurality of limiting blocks 311, which are arranged between adjacent copper pipes 32. The limiting blocks 311 limit the copper pipes 32 to avoid displacement and affect the stability of the connection between the copper pipes 32 and the corresponding connecting terminals 22. At the same time, the limiting blocks 311 separate adjacent copper pipes 32 to avoid short circuit caused by contact between adjacent copper pipes 32, thereby improving the safety of the overall connection circuit.

[0040] In some embodiments, referring to Figure 3 One end of the connecting terminal 22 is inwardly folded to form a resilient sheet, which is in movable contact with the copper pipe 32 for electrical connection. The resilient sheet is pushed towards the copper pipe 32 under the elastic force of the material itself, so that the resilient sheet is always in close contact with the copper pipe 32, effectively ensuring the contact between the connecting terminal 22 and the copper pipe 32, and improving the stability of the electrical connection between the connecting terminal 22 and the copper pipe 32.

[0041] In some embodiments, the rear end of the rotating outer tube 21 is provided with a male terminal 23, and each connecting terminal 22 is electrically connected to one terminal of the male terminal 23 through a single-strand wire; the front end of the rotating inner tube 31 is provided with a female terminal 33, and each copper pipe 32 is electrically connected to one terminal of the female terminal 33 through a single-strand wire. When multiple support tubes 12 are connected, the male terminal 23 is inserted into the female terminal 33 of another support tube 12, thereby realizing the connection of the circuit between the multiple support tubes 12 and ensuring the transmission of control signals and electric energy during the use of the fan.

[0042] In some embodiments, a male terminal block 24 is provided on the outside of the male terminal 23. A male terminal hole 241 is provided at the center of the male terminal block 24 corresponding to the male terminal 23. The shape of the male terminal hole 241 matches the shape of the bottom base of the male terminal 23. The bottom of the male terminal 23 is inserted into the male terminal hole 241, allowing the front end of the male terminal 23 to protrude from the male terminal block 24. By matching the shape of the male terminal hole 241 with the bottom base of the male terminal 23, the male terminal 23 is limited and fixed during assembly with the male terminal block 24, thereby preventing misalignment of the male terminal 23.

[0043] A female terminal block 34 is provided on the outside of the female terminal 33. A female terminal hole 341 is provided at the center of the female terminal block 34 corresponding to the outside of the female terminal 33. A female terminal retaining block 331 is provided on the outside of the female terminal 33. The female terminal retaining block 331 is locked inside the female terminal hole 341 to fix the female terminal 33. The female terminal 33 and the female terminal block 34 are locked and fixed by the female terminal retaining block, thereby improving the stability of the connection between the female terminal 33 and the female terminal block 34.

[0044] In some embodiments, please refer to Figure 6 , Figure 7 The outer end face of the male terminal 24 is provided with a plurality of anti-foolproof holes 242. The outer end face of the female terminal 34 is provided with anti-foolproof blocks 342 corresponding to the anti-foolproof holes 242 of the male terminal 24. The anti-foolproof blocks 342 are inserted into the anti-foolproof holes 242. The dimensions of the corresponding anti-foolproof blocks 342 and the anti-foolproof holes 242 are matched, and the dimensions of the non-corresponding anti-foolproof blocks 342 and the anti-foolproof holes 242 are not matched. By connecting the corresponding anti-foolproof blocks 342 to the anti-foolproof holes 242, a guide is provided for the connection between the male terminal 23 and the female terminal 33, thereby ensuring that the male terminal 23 and the female terminal 33 can be effectively connected. When the anti-misalignment block 342 does not match the anti-misalignment socket 242, it will block the connection between the male terminal 24 and the female terminal 34, preventing the male terminal 23 and the female terminal 33 from being properly inserted. This serves as a reminder to the assembly personnel to adjust the relative position of the male terminal 24 and the female terminal 34 to meet assembly requirements. When connecting the support tube 12, the anti-misalignment socket 242 between the male terminal 23 and the female terminal 33 can be aligned with the anti-misalignment block 342 first. This ensures that the corresponding male terminal 24 and female terminal 34 remain aligned during the connection of the support tube 12, and the insertion of the male terminal 23 and the female terminal 33 is achieved synchronously as the support tube 12 is further connected.

[0045] In some embodiments, please refer to Figure 8The rear end of the rotating inner tube 31 is provided with a threaded hole 312, the inside of the rotating outer tube 21 is provided with a limiting plate 25, the limiting plate 25 is provided with a through hole 251 corresponding to the threaded hole 312 of the rotating inner tube 31, and a screw 35 is locked in the threaded hole 312 through the through hole 251 to achieve the rotatable connection between the rotating outer tube 21 and the rotating inner tube 31. When the screw 35 is locked in the threaded hole 312 through the through hole 251, the ends of the screw 35 are located at both ends of the through hole 251, respectively, of the rotating inner tube 31, so as to limit the relative movement of the rotating outer tube 21 and the rotating inner tube 31 in the axial direction, and ensure the stability of the connection state between the connecting terminal 22 and the copper tube 32. At the same time, the screw 35 serves as the rotating shaft between the rotating inner tube 31 and the rotating outer tube 21, which ensures the relative rotation freedom between the rotating inner tube 31 and the rotating outer tube 21, and meets the requirement of arbitrary rotation between the rotating inner tube 31 and the rotating outer tube 21.

[0046] In some embodiments, the rear end of the rotating inner tube 31 is in a boss structure, the threaded hole 312 is arranged at the center of the boss structure, the boss structure passes through the through hole 251 of the rotating outer tube 21, and then is locked in the threaded hole 312 through the screw 35, so as to limit the axial direction through the ends of the screw 35 and the root of the boss structure, and ensure the stability of the connection state between the connecting terminal 22 and the copper tube 32. At the same time, the boss structure provides the relative rotation freedom, which meets the requirement of arbitrary rotation between the rotating inner tube 31 and the rotating outer tube 21.

[0047] In the second aspect, referring to Figure 9 、 Figure 10 , the application further provides a fan, which comprises a head assembly 1, a support tube assembly and a foot plate assembly 13 arranged from top to bottom, the support tube assembly comprises a plurality of support tubes 12 connected in series, and each group of the support tubes 12 is internally rotatably provided with the support tube 12 wiring structure as described above.

When connecting between the support tubes 12, the external thread 121 and the internal thread 122 of the adjacent support tubes 12 are engaged and rotated, so as to lock and fix the support tubes 12, and at the same time, the male terminal 23 and the female terminal 33 of the two groups of support tubes 12 are inserted, so as to form a transmission end in the inside of the support tube 12, and then the male terminal 23 and the female terminal 33 at both ends of the support tube assembly are connected with the connecting terminals on the head assembly 1 and the foot plate assembly 13, respectively, which meets the requirement of power and control signal transmission for the motor in the head assembly 1, and the power cord can be pulled out from the foot plate assembly 13, which reduces the overhanging section of the power cord, improves the overall appearance and safety under the premise of ensuring the normal work of the fan.

[0048] The method provided by the embodiment of the present application can realize 360-degree free and arbitrary rotation between the support pipe and the rotating outer pipe assembly and the rotating inner pipe assembly, and also between the rotating outer pipe assembly and the rotating inner pipe assembly.
