[0002] Some circulating fans lack a folding and storage function, making them inconvenient to store in winter and taking up space. The few folding fans that do have this function require a fixed switch to lock the folding mechanism, requiring manual operation and resulting in a poor user experience. Utility Model Content

[0003] Based on this, it is necessary to provide a folding locking structure and a circulation fan to address the problem that the circulation fan requires manual locking operation.

[0007] When the abutting portion follows the pressing member to move to the sliding groove, the abutting portion can rotate in the sliding groove, and the pressing member follows the second connecting member to rotate;

[0008] When the abutting portion follows the pressing member to move to the limiting groove, the limiting groove and the abutting portion are engaged in a rotation-stopping manner, and the pressing member limits the rotation of the second connecting member.

[0017] With the above design, when the abutting portion is located in the slide groove and is not aligned with the limiting groove, the flange surface abuts against a side wall of the slide groove to limit the abutting portion from resetting axially into the limiting groove.

[0018] In one embodiment of the first aspect, a buckle is provided on one side where the second connecting portion is connected to the pressing member, and the pressing member is correspondingly provided with a slot, so that after the pressing member is installed on the second connecting portion, the buckle is engaged with the slot.

[0019] Through the above design, the assembly stability of the pressing portion and the second connecting portion is further improved, and the installation and positioning of the pressing member is also facilitated.

[0054] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0055] In the description of this application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0056] In addition, if the term "and / or" appears, "and / or" is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent three situations: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the objects associated with each other are in an "or" relationship. If the terms "first" and "second" appear, these terms are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "multiple" appears, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0057] In this application, unless otherwise specified or limited, the terms "mounted," "connected," "connected," "fixed," etc., should be interpreted broadly. For example, these terms may refer to fixed connections, removable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0058] In this application, unless otherwise expressly specified or limited, if a first feature is described as being "above" or "below" a second feature, or similar descriptions, this may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is described as being "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is described as being "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0059] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only embodiment.

[0060] See Figure 1 As shown, the embodiment of the present application provides a folding locking structure 100 that can be used to fold various vertical electrical appliances, facilitate storage, and maintain stable operation. It should be noted that for ease of understanding, this application uses a circulating fan 1000 as an example application scenario of the folding locking structure 100, but the folding locking structure 100 is not limited to application on the circulating fan 1000.

[0061] See also Figure 2 and Figure 3 As shown, specifically, the folding locking structure 100 is used to foldably connect a first connector and a second connector. The first connector includes a first connecting portion 210, which is provided with a sliding groove 211 and a retaining groove 212 that are interconnected. The second connector includes a second connecting portion 310, which is rotatably connected to the first connecting portion 210. In this way, the folding locking structure 100 allows the second connector to be adjusted in angle relative to the first connector, enabling the second connector to be folded, stored, or unfolded relative to the first connector.

[0062] Furthermore, the folding locking structure 100 includes a locking assembly 110, which is installed at the connection between the second connecting member and the first connecting member, and can rotate with the second connecting member, and when the second connecting member is in an open state, it limits the rotation of the second connecting member to keep the state of the second connecting member and the first connecting member stable.

[0063] Furthermore, the chute 211 and the limiting groove 212 are interconnected, allowing the locking assembly 110 to pass between the limiting groove 212 and the chute 211. In this way, the rotation of the second connecting member is restricted by the position change of the locking assembly 110. When the locking assembly 110 abuts the wall of the limiting groove 212, the limiting groove 212 restricts the rotation of the locking assembly 110 and the second connecting member. When the locking assembly 110 is located in the chute 211, the locking assembly 110 can rotate relative to the chute 211, thereby rotating with the second connecting member.

[0064] Continue reading Figure 4 As shown, further, the second connecting portion 310 is provided with a U-shaped notch and has two oppositely arranged rotating shafts 311. The first connecting portion 210 is correspondingly provided with a cavity that rotates with the rotating shafts 311, and the second connecting member is rotatably connected to the first connecting portion 210 through the rotating shafts 311.

[0065] Furthermore, the locking assembly 110 includes a pressing member 111 . The pressing member 111 is installed at the rotational connection between the second connecting portion 310 and the first connecting portion 210 and can rotate along with the second connecting portion.

[0066] See also Figure 5 、 Figure 6 and Figure 7 Specifically, the second connecting portion 310 is further provided with a plurality of positioning blocks 312. Each positioning block 312 is disposed at the end of the rotating shaft 311 away from the first connecting portion 210 and is distributed circumferentially about the axis of the rotating shaft 311. The pressing member 111 has a cavity defined therein, allowing the pressing member 111 to be inserted into the outer side of the positioning blocks 312, allowing the pressing member 111 to be mounted on the second connecting portion 310 and to telescopically slide relative to the positioning blocks 312.

[0067] Preferably, a plurality of positioning grooves 1114 can be provided inside the pressing member 111, so that when the pressing member 111 is plugged into the positioning block 312, the positioning block 312 is inserted into the positioning grooves 1114, thereby achieving rapid assembly of the pressing member 111 and the second connecting portion 310. At the same time, the cooperation between the positioning grooves 1114 and the positioning block 312 can limit the installation angle of the pressing member 111, thereby achieving precise positioning and assembly of the pressing member 111.

[0068] See again Figure 6 and Figure 7As shown, in some embodiments, a buckle 313 is provided on one side where the second connecting portion 310 is connected to the pressing member 111, and a corresponding slot 1113 is provided on the pressing member 111. After the pressing member 111 is installed on the second connecting portion 310, the buckle 313 engages with the slot 1113. The engagement of the buckle 313 with the slot 1113 further improves the assembly stability of the pressing portion and the second connecting portion 310, and also facilitates the installation and positioning of the pressing member 111.

[0069] See also Figure 7 and Figure 8 As shown, further, the pressing member 111 is telescopically arranged to pass through the limiting groove 212 and is provided with an abutting portion 1111. Through the axial telescopic movement of the pressing member 111, the position of the abutting portion 1111 between the sliding groove 211 and the limiting groove 212 is adjusted. At the same time, the abutting portion 1111 and the limiting groove 212 are engaged to prevent rotation, thereby limiting the rotation of the second connecting portion 310 in the expanded state.

[0070] Specifically, the side of the pressing member 111 away from the second connecting portion 310 is a solid pressing surface, so that when an external force acts on the pressing surface, the pressing member 111 can move along the axial direction. The abutment portion 1111 is provided at the end of the pressing member 111 away from the pressing surface. The second connecting portion 310 is also provided with a through hole 314. The cavity structure of the through hole 314 is adapted to the abutment portion 1111, so that the abutment portion 1111 enters the limiting groove 212 through the hole 314 during the assembly process of the pressing member 111, and then enters the slide groove 211 through the limiting groove 212 during the pressing process of the pressing member 111.

[0071] Exemplarily, when the second connector is unfolded relative to the first connector, the abutting portion 1111 is located in the limiting groove 212. The wall surface of the limiting groove 212 contacts the abutting portion 1111, so that the pressing member 111 cannot rotate arbitrarily, thereby limiting the rotation of the second connector and maintaining the stability of the second connector in the unfolded state without the need for an additional manual locking switch, reducing manpower and facilitating operation. When the second connector needs to be folded, it is only necessary to press the pressing surface of the pressing member 111 to move the pressing member 111 toward the inner side of the second connector 310, and the abutting portion 1111 will break away from the wall surface of the limiting groove 212 and enter the interior of the chute 211. The abutting portion 1111 can move with the second connector in the chute 211, and then the second connector can be rotated so that the second connector and the first connector are folded for easy storage.

[0072] See again Figure 7 and Figure 8As shown, in some embodiments, the abutting portion 1111 includes an arcuate surface 11111 and two first resisting surfaces 11112 distributed at both ends of the arcuate surface 11111. Two second resisting surfaces 2121 are provided opposite to the limiting groove 212. When the abutting portion 1111 is located in the limiting groove 212, each second resisting surface 2121 abuts against the corresponding first resisting surface 11112.

[0073] Specifically, the first resisting surface 11112 and the second resisting surface 2121 are both planar structures, so that the abutting portion 1111 and the limiting groove 212 are not regular circular structures. When the abutting portion 1111 is located in the limiting groove 212, the first resisting surface 11112 and the second resisting surface 2121 interfere with each other, and the pressing member 111 cannot rotate within the limiting groove 212.

[0074] See also Figure 7 and Figure 9 As shown, the pressing member 111 further includes a main body 1112. The abutting portion 1111 is provided at one end of the main body 1112 near the first connecting portion 210 and protrudes relative to the peripheral surface of the main body 1112 to form a flange surface 11113. When the abutting portion 1111 is located in the slide groove 211 and is not aligned with the limiting groove 212, the flange surface 11113 abuts against a side wall of the slide groove 211 to prevent the abutting portion 1111 from returning axially into the limiting groove 212.

[0075] It is understandable that due to the setting of the first resisting surface 11112, the distance between the axis of the pressing member 111 and the first resisting surface 11112 is smaller than the distance between the axis and the arc surface. In order to enable the abutting portion 1111 to rotate within the chute 211, the chute 211 needs to be set with the distance between the axis of the pressing member 111 and the arc surface as the radius. Therefore, the limiting groove 212 is narrowed relative to the chute 211. When the abutting portion 1111 is not completely aligned with the limiting groove 212, the abutting portion 1111 is blocked by the connecting wall of the chute 211 and the limiting groove 212 and cannot return to the limiting groove 212, thereby preventing the abutting portion 1111 from returning to the limiting groove 212 in the folded state of the second connecting member, and requiring the pressing member 111 to be pressed again to unfold the second connecting member.

[0076] See again Figure 2 As shown, in some embodiments, the locking assembly 110 further includes an elastic member 112 , and two ends of the elastic member 112 are respectively connected to the pressing member 111 and the second connecting member.

[0077] Specifically, the elastic member 112 can be a helical compression spring, with its two ends connected to the pressing member 111 and the second connecting member, respectively, to achieve the pressing and resetting of the pressing member 111. In a normal state, the elastic member 112 is in a stretched state, pressing the pressing member 111 outward, so that the abutting portion 1111 is located within the limiting groove 212. During the rotation of the second connecting member, the pressing member 111 is pressed, causing the elastic member 112 to contract, and the abutting portion 1111 to enter the sliding groove 211, so that the pressing member 111 rotates with the second connecting member.

[0078] For example, when the second connecting member is in the folded state, the elastic member 112 presses the pressing member 111 outward due to its elastic potential energy, causing the abutting portion 1111 to abut against the wall of the sliding groove 211 and prevent it from returning to the limiting groove 212. When the second connecting member is rotated to the unfolded state, the abutting portion 1111 is completely aligned with the limiting groove 212, and the elastic member 112 presses the pressing member 111 outward, causing the abutting portion 1111 to enter the limiting groove 212 and be unable to rotate due to the restriction of the limiting groove 212 wall.

[0079] In some embodiments, the folding locking structure 100 further includes a connecting assembly 120, which includes a plug 121 and a locking member 122. The plug 121 sequentially passes through the first connecting portion 210 and the second connecting portion 310, so that the second connecting member rotates relative to the first connecting member about the plug 121. The locking member 122 is provided at one end of the plug 121 to limit the plug 121 and prevent it from falling off during rotation.

[0080] Continue reading Figure 10 As shown, in one embodiment, the insertion member 121 can be a bolt, and the locking member 122 can be a nut. The first connecting portion 210 and the second connecting portion 310 are both provided with corresponding connection holes. After the bolt passes through the first connecting portion 210 and the second connecting portion 310, it is locked and limited by the nut to allow the second connecting member to rotate relative to the first connecting member without falling off the raised frame during the movement.

[0081] In another embodiment, the insertion member 121 may be a pin with limit holes at both ends, and the locking member 122 may be a corresponding cotter pin, so that the cotter pin passes through the limit block of the pin to limit the pin, allowing the second connecting member to be installed on the first connecting member. Of course, in other embodiments, the second connecting member and the first connecting member may also be connected in a manner that satisfies the need for rotational connection between the second connecting member and the first connecting member, and this is not specifically limited here.

[0082] In some embodiments, the folding locking structure 100 further includes a plurality of friction plates. The first connecting portion 210 is provided with a plurality of mounting slots 214 . Each friction plate is mounted in a corresponding mounting slot 214 , and the insert 121 is passed through each friction plate in sequence.

[0083] Exemplarily, two friction plates and two mounting slots 214 are provided, and the two friction plates are symmetrically arranged on either side of the second connecting portion 310. During installation, the insert 121 sequentially passes through one friction plate, the second connecting member, and the other friction plate, and is then secured to the locking member 122. As the second connecting member rotates, the friction plate provides friction to the second connecting member, offsetting some of the potential energy of the second connecting member during rotation, reducing the rotational speed of the second connecting member, and minimizing component wear.

[0084] The present application also provides a circulating fan 1000, comprising a body assembly 200, a head assembly 300, and the folding locking structure 100 of any of the above-described embodiments. The folding locking structure 100 is foldably connected between the body assembly 200 and the head assembly 300. With the folding locking structure 100, the circulating fan 1000 can be freely folded and stored, making it easier to store and reducing space.

[0085] This embodiment has the folding locking structure 100 of any of the above embodiments, and therefore has all the beneficial effects of the folding locking structure 100 of any of the above embodiments, which will not be described in detail here.

[0086] It can be understood that in this embodiment, the body assembly 200 can be referred to as the first connecting member in the above embodiment, and the head assembly 300 can be referred to as the second connecting member in the above embodiment.

[0087] See also Figure 3 、 Figure 8 and Figure 11 In some embodiments, a wiring hole 315 is provided on the side of the second connecting portion 310 away from the pressing member 111, and a wiring groove 213 and a wire clamping groove 215 are provided on the first connecting portion 210. The wiring hole 315, the wiring groove 213 and the wire clamping groove 215 are used for internal wiring layout of the folding locking structure 100.

[0088] As is understandable, all electrical equipment requires wiring to electrically connect the various internal electronic components. To enhance the overall aesthetics of the device, this embodiment of the present application arranges the wiring inside the folding locking structure 100 to reduce the exposure of the external wiring. The wiring passes through the wiring hole 315 of the head assembly 300 and exits through the wiring groove 213 of the body assembly 200. The wiring is then secured by the wire clamping groove 215 of the body assembly 200.

[0089] Continue reading Figure 12 As shown, in some embodiments, the fuselage assembly 200 includes a second connecting portion 310 and an upper cover 220. The upper cover 220 is covered on the first connecting portion 210 and is provided with a wire retaining rib 221. The wire retaining rib 221 is located on one side of the upper cover 220 close to the first connecting portion 210 and is engaged with the wire retaining groove 215.

[0090] Specifically, the upper cover 220 is detachably connected to the first connecting portion 210. The upper cover 220 is provided with a latching block, and the first connecting portion 210 is provided with a corresponding connecting slot to engage with the upper cover 220. In other embodiments, the upper cover 220 and the first connecting portion 210 may also be secured with screws, which are not specifically limited here. When the upper cover 220 is installed on the first connecting portion 210, the wire retaining ribs are inserted into the corresponding wire retaining slots 215 in the first connecting portion 210, thereby restricting the movement of the wiring and preventing interference with the wiring during the rotation of the second connecting member.

[0091] Furthermore, the head assembly 300 includes a second connecting portion 310 and a cover plate 330. The cover plate 330 is disposed on the side of the second connecting portion 310 to shield the internal cavity of the second connecting portion 310. The cover plate 330 and the second connecting portion 310 can each be provided with a latch and a connection groove to facilitate assembly and mating. In other embodiments, the cover plate 330 and the second connecting portion 310 can also be fastened with screws, which is not specifically limited here.

[0092] Furthermore, the nose assembly 300 further includes a fan body 320 , which is rotatably mounted on an end of the second connecting portion 310 away from the first connecting portion 210 .

[0093] Specifically, the fan body 320 may include blades and a drive motor. When powered, the drive motor rotates the blades to dissipate heat. The second connecting portion 310 has a Y-shaped structure, with its bottom end rotatably connected to the first connecting member. The fan body 320 is mounted between the upper ends of the second connecting portion 310 and is rotatably connected to the upper ends of the second connecting portion 310, thereby ensuring stable installation of the fan body 320. During operation, the fan body 320 can rotate relative to the second connecting portion 310 to adjust the operating angle.

[0094] Continue reading Figure 13 and Figure 14 As shown, in some embodiments, the circulation fan 1000 further includes a support assembly 400 and a chassis 500. The support assembly 400 includes a plurality of telescopic rods 410, and each telescopic rod 410 is slidably connected in sequence. It can be understood that each telescopic rod 410 is a hollow tube structure with different outer diameters to achieve the mutual connection of each telescopic rod 410. 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 410. 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 410.

[0095] In addition, the bottom end of the support assembly 400 is detachably connected to the chassis 500. During assembly of the circulation fan 1000, the support assembly 400 is locked to the chassis 500, thereby connecting to the bottom surface through the chassis 500, ensuring the stable support of the circulation fan 1000 when it is in a standing position. When the circulation fan 1000 is folded and stored, the support assembly 400 can be separated from the chassis 500, further reducing the space occupied by the circulation fan 1000.
