[0061] See also Figure 1 and Figure 3 As shown, the embodiment of the present application provides a folding wiring structure 100, which can be used for internal wiring of rotating parts of various electrical appliances to reduce the accidents of wiring 130 breakage caused by folding. It should be noted that, for ease of understanding, the present application uses a circulation fan 1000 as an example application scenario of the folding wiring structure 100, but the folding wiring structure 100 is not limited to the application on the circulation fan 1000.

[0062] Continue reading Figure 2 and Figure 4 As shown, specifically, the folding wiring structure 100 includes a first connector 110, a second connector 120 and a wiring 130. The first connector 110 and the second connector 120 are rotatably connected to realize the folding, storage or unfolding operation of the first connector 110 and the second connector 120. The wiring 130 is arranged around the rotation connection between the first connector 110 and the second connector 120, and is arranged inside the first connector 110 and the second connector 120, and can rotate with the second connector 120, but the two ends of the wiring 130 are respectively restricted in the first connector 110 and the second connector 120, so as to reduce the risk of the wiring 130 being broken due to the pulling generated during the rotation of the wiring 130.

[0063] Furthermore, the first connector 110 is provided with a first wiring cavity 1111, and a wiring groove 1112 and a first wire clamping groove 1113 are provided in the first wiring cavity 1111. The second connector 120 is provided with a second wiring cavity 1211, and a wiring hole 1212 communicating with the second wiring cavity 1211 is provided on one side, so as to conduct the second wiring cavity 1211 to the first wiring cavity 1111 through the wiring hole 1212. In this way, the wiring 130 passes through the wiring groove 1112, the first wire clamping groove 1113 and the wiring hole 1212 in sequence, so as to realize the layout of the wiring 130 in the first connector 110 and the second connector 120.

[0064] At the same time, one end of the wiring 130 is fixed in the first wiring cavity 1111 through the first wire clamping groove 1113, and the other end of the wiring 130 is passed through the second wiring cavity 1211 through the wiring hole 1212. When the second connector 120 rotates relative to the first connector 110, one end of the wiring 130 is fixed by the first wire clamping groove 1113, limiting the movement of the wiring 130 within a short distance, avoiding the risk of long-distance wiring, messy lines, and easy pulling and breaking. At the same time, the wiring 130 retains a certain bending length at the wiring hole 1212, so that the wiring 130 has a certain amount of movement margin during the rotation of the second connector 120, further avoiding the wiring 130 from being pulled and broken.

[0065] Continue reading Figure 5 and Figure 6 As shown, further, the first connecting member 110 includes a first connecting portion 111 and an upper cover 112, the upper cover 112 covers the first connecting portion 111 and defines a first wiring cavity 1111 with the first connecting portion 111. A first wire clamping groove 1113 is provided on the first connecting portion 111, and the upper cover 112 is provided with a wire retaining rib 1121, which is engaged with the first wire clamping groove 1113.

[0066] Exemplarily, the upper cover 112 is detachably connected to the first connecting member 110, the upper cover 112 is provided with a clamping block, and the first connecting member 110 is correspondingly provided with a connecting groove to engage with the upper cover 112. In other embodiments, the upper cover 112 and the first connecting member 110 may also be locked with screws, which is not specifically limited here.

[0067] Specifically, the first wire clamping groove 1113 is a U-shaped groove structure with an opening on the upper side. When the upper cover 112 is installed on the first connecting member 110, the wire retaining rib 1121 is inserted into the open side of the first wire clamping groove 1113. The wire retaining rib 1121 and the wall surface of the first wire clamping groove 1113 define an on-site rectangular groove to tightly restrict the sides of the wiring 130 in four directions, thereby limiting the stretching of the end of the wiring 130.

[0068] Continue reading Figure 7 and Figure 8 As shown, in some embodiments, a second wire clamping groove 1213 is opened in the second wire routing cavity 1211 , and one end of the wiring 130 located in the second wire routing cavity 1211 is clamped in the second wire clamping groove 1213 .

[0069] Specifically, the second wire clamping groove 1213 is arranged on the same side as the wiring hole 1212, and the second wire clamping groove 1213 can be provided with multiple, such as two, three, four, etc., which can be arranged specifically according to actual needs. In this way, one end of the wiring 130 is fixed in the first wiring cavity 1111 by the first wire clamping groove 1113, and the other end enters the second wiring cavity 1211 through the wiring hole 1212 and is restricted by the second wire clamping groove 1213, thereby reducing the lateral movement of the wiring 130. At the same time, through the arrangement of multiple second wire clamping grooves 1213, the wiring 130 is arranged along the extension direction of the structural structure of the second connecting member 120, and the wiring 130 is integrated into the first connecting member 110 and the second connecting member 120, and can rotate with the second connecting member 120, and there is no pulling damage during the movement. The two ends of the wiring 130 are respectively limited by the first wire clamping groove 1113 and the second wire clamping groove 1213, so that the wiring 130 cannot rotate along its own axis, and the problem of the wiring 130 reducing its elasticity due to its own rotation and being easily broken by external force will not occur.

[0070] In some embodiments, the second connecting member 120 includes a second connecting portion 121 and a cover plate 122, wherein the cover plate 122 covers the second connecting portion 121 and defines a second wiring cavity 1211 with the second connecting portion 121 to cooperate with the second wire clamping groove 1213 to confine one end of the wiring 130 away from the first wiring cavity 1111 within the second wiring cavity 1211.

[0071] Exemplarily, the cover plate 122 and the second connection portion 121 may be provided with a block and a connection groove respectively to achieve assembly and cooperation between them. In other embodiments, the cover plate 122 and the second connection portion 121 may also be locked with screws, which is not specifically limited here. In this way, through the cooperation between the cover plate 122 and the second connection portion 121, the wiring 130 is confined in the second wiring cavity 1211, the pulling movement of the wiring 130 is reduced, and the wiring 130 is shielded, thereby improving the overall appearance.

[0072] Furthermore, the second connecting member 120 includes a first end face 1215, a curved surface 1216 and a second end face 1217 arranged on the side of the wiring hole 1212. The first end face 1215, the curved surface 1216 and the second end face 1217 are distributed in sequence on three adjacent sides of the wiring hole 1212. The first end face 1215 and the second end face 1217 are used to limit the movement angle of the wiring 130 so that the wiring 130 will not produce a large displacement, thereby reducing the risk of the wiring 130 being pulled and broken.

[0073] Specifically, since the two ends of the wiring 130 are limited, a certain amount of movement is reserved for the wiring 130 at the wiring hole 1212 to follow the flipping and bending of the second connector 120. In the folded or unfolded state of the second connector 120, the wiring 130 abuts against the first end face 1215 and the second end face 1217, respectively, thereby limiting the movement angle of the wiring 130 and reducing the pulling loss of the wiring 130.

[0074] Furthermore, the arcuate surface 1216 is provided with a transition fillet, and during the movement of the wiring 130, the transition fillet abuts against the wiring 130. It can be understood that during the rotational movement of the second connecting member 120, the wiring 130 inevitably contacts the arcuate surface 1216 of the second connecting member 120, so that the friction resistance between the wiring 130 and the arcuate surface 1216 is reduced by setting the transition fillet, and the wear caused by the friction between the wiring 130 and the sharp edge is avoided.

[0075] In some embodiments, the first end face 1215 and the second end face 1217 form a preset angle, and the preset angle has an angle range of 120° to 240°.

[0076] Exemplarily, the first end face 1215 and the second end face 1217 can be used to limit the curvature of the arc surface 1216, so as to limit the bending angle and displacement of the wiring 130 according to the flip angle of the second connection. The preset angle can be 120°, 150°, 180°, 210°, 240°, etc., which can be selected according to actual needs, and can meet the requirements that the wiring 130 moves following the rotation of the second connector 120.

[0077] In some embodiments, the width of the wiring groove 1112 is greater than or equal to 15 mm.

[0078] For example, in conventional household appliances, the diameter of the wiring 130 is usually less than 15 mm, so that the wiring 130 can be completely placed in the wiring groove 1112 through the groove width setting of the wiring groove 1112, completing the wiring setting of the wiring 130. Preferably, the groove width of the wiring groove 1112 can be 0.1 mm-0.2 mm larger than the diameter of the wiring 130, which can meet the requirements of placing the wiring 130 while limiting the range of movement of the wiring 130, avoiding the wiring 130 from generating a large displacement during the rotation of the second connector 120, resulting in the risk of pulling and breaking.

[0079] An embodiment of the present application also provides a circulation fan 1000, including a body assembly 200, a head assembly 300 and a folding wiring structure 100 in any of the above embodiments, the body assembly 200 is fixedly connected to the first connecting member 110, and the head assembly 300 is rotatably connected to the second connecting member 120.

[0080] Specifically, the circulation fan 1000 is supported by the body assembly 200 and is placed upright on the ground or a table in the operating state. The head assembly 300 is rotatably connected to the second connecting member 120, so that it can rotate relative to the second connecting member 120 to adjust the operating angle. The first connecting member 110 is fixed to the body assembly 200, so that the head assembly 300 and the second connecting member 120 can rotate relative to the body to achieve the folding, storage or unfolding operation of the head assembly 300.

[0081] This embodiment has the folded wiring structure 100 in any of the above embodiments, and therefore has all the beneficial effects of the folded wiring structure 100 in any of the above embodiments, which will not be described in detail here.

[0082] Furthermore, the head assembly 300 may include a fan blade and a drive motor, and when powered on, the drive motor drives the fan blade to rotate to perform heat dissipation. The second connecting member 120 is a Y-shaped structure, and its bottom end is rotatably connected to the first connecting member 110. The head assembly 300 is installed between the upper ends of the second connecting member 120 and is rotatably connected to the upper ends of the second connecting member 120, thereby achieving stable installation of the head assembly 300, and during operation, the head assembly 300 can rotate relative to the second connecting member 120 to adjust the operating angle.

[0083] Continue reading Fig. 9 and Fig.10 As shown, in some embodiments, the circulation fan 1000 also includes a locking assembly 500, the locking assembly 500 includes a pressing member 510, the first connecting member 110 is provided with a sliding groove 1115 and a limiting groove 1116 that are interconnected, the pressing member 510 is installed at the rotational connection between the second connecting member 120 and the first connecting member 110, and can rotate with the second connecting member 120, and the pressing member 510 can be telescopically inserted into the limiting groove 1116 and is provided with an abutment portion 511.

[0084] When the abutting portion 511 follows the pressing member 510 to move to the slide groove 1115, the abutting portion 511 can rotate in the slide groove 1115, and the pressing member 510 follows the rotation of the second connecting member 120. When the abutting portion 511 follows the pressing member 510 to move to the limiting groove 1116, the limiting groove 1116 and the abutting portion 511 are locked, and the pressing member 510 limits the rotation of the second connecting member 120.

[0085] Specifically, the side of the pressing member 510 away from the second connecting member 120 is a solid pressing surface, so that when an external force acts on the pressing surface, the pressing member 510 can move along the axial direction. The abutment portion 511 is provided at one end of the pressing member 510 away from the pressing surface, and the second connecting member 120 is also provided with a through hole, and the cavity structure of the through hole is adapted to the abutment portion 511, so that the abutment portion 511 enters the limiting groove 1116 through the hole during the assembly process of the pressing member 510, and then enters the slide groove 1115 through the limiting groove 1116 during the pressing process of the pressing member 510.

[0086] Exemplarily, when the second connecting member 120 is unfolded relative to the first connecting member 110, the abutting portion 511 is located in the limiting groove 1116. The wall surface of the limiting groove 1116 abuts against the abutting portion 511, so that the pressing member 510 cannot rotate arbitrarily, thereby limiting the rotation of the second connecting member 120, maintaining the stability of the second connecting member 120 in the unfolded state, without the need to set an additional manual locking switch, reducing manpower and facilitating operation. When the second connecting member 120 needs to be folded, it is only necessary to press the pressing surface of the pressing member 510 to move the pressing member 510 toward the inner side of the second connecting member 120, and the abutting portion 511 is separated from the wall surface of the limiting groove 1116 and enters the interior of the slide groove 1115. The abutting portion 511 can move with the second connecting member 120 in the slide groove 1115, and then the second connecting member 120 is rotated, so that the second connecting member 120 and the first connecting member 110 are folded, which is convenient for storage.

[0087] Furthermore, the abutting portion 511 includes an arcuate surface 1216 and two first resisting surfaces distributed at both ends of the arcuate surface 1216. The limiting groove 1116 is provided with two second resisting surfaces opposite to each other. When the abutting portion 511 is located in the limiting groove 1116, each second resisting surface abuts against the corresponding first resisting surface.

[0088] Specifically, the first resisting surface and the second resisting surface are both planar structures, so that the abutting portion 511 and the limiting groove 1116 are not regular circular structures. When the abutting portion 511 is located in the limiting groove 1116, the first resisting surface conflicts with the second resisting surface, and the pressing member 510 cannot rotate in the limiting groove 1116.

[0089] Furthermore, the pressing member 510 includes a main body 512, and the abutting portion 511 is disposed at one end of the main body 512 close to the first connecting member 110, and protrudes relative to the peripheral surface of the main body 512 to form a flange surface. When the abutting portion 511 is located in the slide groove 1115 and is not aligned with the limiting groove 1116, the flange surface abuts against a side wall of the slide groove 1115 to limit the abutting portion 511 from being reset axially into the limiting groove 1116.

[0090] It is understandable that due to the setting of the first resisting surface, the distance between the axis of the pressing member 510 and the first resisting surface is smaller than the distance between the axis and the arc surface, and in order to allow the abutting portion 511 to rotate in the slide groove 1115, the slide groove 1115 needs to be set with the distance between the axis of the pressing member 510 and the arc surface as the radius. Therefore, the limiting groove 1116 is narrowed relative to the slide groove 1115, and when the abutting portion 511 is not completely aligned with the limiting groove 1116, the abutting portion 511 is blocked by the connecting wall of the slide groove 1115 and the limiting groove 1116 and cannot be reset to the limiting groove 1116, thereby avoiding the abutting portion 511 from being reset to the limiting groove 1116 in the folded state of the second connecting member 120, and the pressing member 510 needs to be pressed again to unfold the second connecting member 120.

[0091] In some embodiments, the locking assembly 500 further includes an elastic member 520 , and two ends of the elastic member 520 are respectively connected to the pressing member 510 and the second connecting member 120 .

[0092] Specifically, the elastic member 520 may be a helical compression spring, and its two ends are respectively connected to the pressing member 510 and the second connecting member 120 to achieve the pressing and resetting of the pressing member 510. In a normal state, the elastic member 520 is in a stretched state, pressing the pressing member 510 outward, so that the abutting portion 511 is located in the limiting groove 1116. During the rotation of the second connecting member 120, by pressing the pressing member 510, the elastic member 520 contracts, the abutting portion 511 enters the sliding groove 1115, and the pressing member 510 rotates with the second connecting member 120.

[0093] For example, when the second connecting member 120 is in the folded state, the elastic member 520 presses the pressing member 510 outward due to the elastic potential energy, so that the abutting portion 511 is pressed against the wall of the sliding groove 1115 and cannot be reset into the limiting groove 1116. When the second connecting member 120 is rotated to the unfolded state, the abutting portion 511 is completely aligned with the limiting groove 1116, and the elastic member 520 presses the pressing member 510 outward, so that the abutting portion 511 enters the limiting groove 1116 and cannot rotate under the restriction of the wall of the limiting groove 1116.

[0094] Continue reading Fig.11 As shown, in some embodiments, the second connecting member 120 has a U-shaped notch and two oppositely disposed rotating shafts 1214. The first connecting member 110 is correspondingly provided with a cavity that rotates with the rotating shaft 1214, and the second connecting member 120 is rotatably connected to the first connecting member 110 through the rotating shaft 1214.

[0095] Furthermore, the second connecting member 120 is also provided with a plurality of positioning blocks, each of which is provided at one end of the rotating shaft 1214 away from the first connecting member 110 and is circumferentially distributed with the axis of the rotating shaft 1214 as the axis. A cavity is provided inside the pressing member 510 so that the pressing member 510 can be inserted into the outer side of the positioning block, so that the pressing member 510 is installed on the second connecting member 120 and can telescopically slide relative to the positioning block.

[0096] Preferably, a plurality of positioning grooves may be provided inside the pressing member 510, so that when the pressing member 510 is plugged and matched with the positioning block, the positioning block is inserted into the positioning groove, thereby realizing rapid assembly of the pressing member 510 and the second connecting member 120. At the same time, the cooperation between the positioning groove and the positioning block can limit the installation angle of the pressing member 510, thereby realizing accurate positioning and assembly of the pressing member 510.

[0097] Furthermore, a buckle is provided on one side where the second connecting member 120 is connected to the pressing member 510, and a slot is provided on the pressing member 510 accordingly, so that after the pressing member 510 is installed on the second connecting member 120, the buckle and the slot are engaged and matched. Through the engagement and matching of the buckle and the slot, the assembly stability of the pressing portion and the second connecting member 120 is further improved, and the installation and positioning of the pressing member 510 is also facilitated.

[0098] In some embodiments, the circulation fan 1000 further includes a connection assembly 600, which includes a plug-in assembly 610 and a locking member, wherein the plug-in assembly 610 sequentially passes through the first connection member 110 and the second connection member 120, so that the second connection member 120 rotates relative to the first connection member 110 with the plug-in assembly 610 as the axis. The locking member is disposed at one end of the plug-in assembly 610 to limit the plug-in assembly 610 and prevent the plug-in assembly 610 from falling off during rotation.

[0099] In one embodiment, the insertion member 610 may be a bolt, and the locking member may be a nut. The first connecting member 110 and the second connecting member 120 are both provided with corresponding connection holes. After the bolt passes through the first connecting member 110 and the second connecting member 120, the nut is used to lock and limit the position, so that the second connecting member 120 can rotate relative to the first connecting member 110 and will not fall off the raised frame during the movement.

[0100] In another embodiment, the insertion plug 610 may also be a pin shaft, and limit holes are provided at both ends, and the locking member may be a cotter pin, so that the cotter pin passes through the limit block of the pin shaft to limit the pin shaft, so that the second connecting member 120 is installed on the first connecting member 110. Of course, in other embodiments, the second connecting member 120 and the first connecting member 110 may also be connected in a manner that satisfies the rotational connection between the second connecting member 120 and the first connecting member 110, which is not specifically limited here.

[0101] In some embodiments, the circulation fan 1000 further includes a plurality of friction plates 140 , the first connecting member 110 is provided with a plurality of mounting grooves 1114 , each friction plate 140 is respectively installed in a corresponding mounting groove 1114 , and the inserting member 610 is inserted through each friction plate 140 in sequence.

[0102] Exemplarily, two friction plates 140 and two mounting grooves 1114 are provided, and the two friction plates 140 are symmetrically arranged on both sides of the second connecting member 120. During the installation process, the insertion member 610 passes through one friction plate 140, the second connecting member 120 and another friction plate 140 in sequence and is fixed to the locking member, so that during the rotation process of the second connecting member 120, the friction plate 140 will provide friction force to the second connecting member 120, offset part of the potential energy of the second connecting member 120 during the rotation process, reduce the rotation speed of the second connecting member 120, and reduce the loss of components.

[0103] Continue reading Fig.12 , Fig.13 and Fig.14 As shown, in some embodiments, the circulation fan 1000 also includes a chassis 400. The fuselage assembly 200 includes a plurality of telescopic rods 210, and each telescopic rod 210 is slidably connected in sequence. It can be understood that each telescopic rod 210 is a hollow tube structure with different outer diameters to achieve mutual connection of each telescopic rod 210. The specific principle is not described in detail here. The operating height adjustment of the circulation fan 1000 is achieved by adjusting the telescopic rod 210. At the same time, during the folding and storage process, the storage space of the circulation fan 1000 can be further reduced by contracting the telescopic rod 210.

[0104] In addition, the bottom end of the body assembly 200 is detachably connected to the chassis 400. When the circulation fan 1000 is assembled, the body assembly 200 is locked with the chassis 400, so that the chassis 400 is connected to the bottom surface to ensure the support stability of the circulation fan 1000 when it is in a standing working state. When the circulation fan 1000 is folded and stored, the body assembly 200 can be separated from the chassis 400 to further reduce the space occupied by the circulation fan 1000.

[0105] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0106] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
