However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0055] In the description of the present 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 the present 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 the present 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: 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 before and after 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 clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0058] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it 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. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in 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 a central 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 a central element at the same time. 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 implementation method.

[0060] See also Figure 1 As shown, the embodiment of the present application provides a folding locking structure 100, which can be used for the folding needs of various vertical electrical appliances, which is convenient for storage and maintains stable operation. It should be noted that, for ease of understanding, the present 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 the 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 the first connecting member and the second connecting member. The first connecting member includes a first connecting portion 210, and the first connecting portion 210 is provided with a sliding groove 211 and a limiting groove 212 that are interconnected. The second connecting member includes a second connecting portion 310, and the second connecting portion 310 is rotatably connected to the first connecting portion 210. In this way, the connection angle of the second connecting member relative to the first connecting member is adjusted by the folding locking structure 100, and the folding, storage or opening operation of the second connecting member and the first connecting member is realized.

[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, limit 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 slide groove 211 and the limiting groove 212 are interconnected, so that the locking assembly 110 can pass between the limiting groove 212 and the slide groove 211. In this way, the rotation of the second connecting member is limited by the position change of the locking assembly 110. When the locking assembly 110 abuts against the wall surface of the limiting groove 212, the limiting groove 212 can limit the rotation of the locking assembly 110 and the second connecting member. When the locking assembly 110 is located in the slide groove 211, the locking assembly 110 can rotate relative to the slide groove 211, thereby rotating with the second connecting member.

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

[0065] Furthermore, the locking assembly 110 includes a pressing member 111 , which 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 As shown, specifically, the second connection part 310 is further provided with a plurality of positioning blocks 312, each positioning block 312 is provided at one end of the rotating shaft 311 away from the first connection part 210, and is circumferentially distributed with the axis of the rotating shaft 311 as the axis. A cavity is provided inside the pressing member 111, so that the pressing member 111 can be inserted into the outer side of the positioning block 312, so that the pressing member 111 is installed on the second connection part 310, and can be telescopically slidable relative to the positioning block 312.

[0067] Preferably, a plurality of positioning grooves 1114 may be provided inside the pressing member 111, so that when the pressing member 111 is plugged and matched with the positioning block 312, the positioning block 312 is inserted into the positioning groove 1114, thereby realizing rapid assembly of the pressing member 111 and the second connecting portion 310. At the same time, the cooperation between the positioning groove 1114 and the positioning block 312 can limit the installation angle of the pressing member 111, thereby realizing accurate 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 connection portion 310 is connected to the pressing member 111, and a slot 1113 is correspondingly provided on the pressing member 111, so that after the pressing member 111 is installed on the second connection portion 310, the buckle 313 and the slot 1113 are engaged and matched. Through the connection and matching between the buckle 313 and the slot 1113, the assembly stability of the pressing portion and the second connection portion 310 is further improved, and the installation and positioning of the pressing member 111 is also facilitated.

[0069] See also Figure 7 and Figure 8 As shown, further, the pressing member 111 is telescopically arranged in the limiting groove 212 and is provided with an abutting portion 1111, and the position of the abutting portion 1111 in the sliding groove 211 and the limiting groove 212 is adjusted by axial telescopic movement of the pressing member 111. At the same time, the abutting portion 1111 is anti-rotationally matched with the limiting groove 212, thereby limiting the rotation of the second connecting portion 310 in the unfolded state.

[0070] Specifically, the side of the pressing member 111 away from the second connection part 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 one end of the pressing member 111 away from the pressing surface, and the second connection part 310 is further provided with a through hole 314, and 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 abutment portion 1111 is located in the limiting groove 212. The wall surface of the limiting groove 212 abuts against the abutment portion 1111, so that the pressing member 111 cannot rotate arbitrarily, thereby limiting the rotation of the second connector, maintaining the stability of the second connector in the unfolded state, without the need to set up 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 abutment portion 1111 is separated from the wall surface of the limiting groove 212 and enters the interior of the slide groove 211. The abutment portion 1111 can move with the second connector in the slide groove 211, and then the second connector is 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. The limiting groove 212 is provided with two second resisting surfaces 2121 opposite to each other. 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 are in conflict, and the pressing member 111 cannot rotate in the limiting groove 212.

[0074] See also Figure 7 and Fig. 9 As shown, further, the pressing member 111 includes a main body 1112, and the abutting portion 1111 is disposed at one end of the main body 1112 close to 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 surface of the slide groove 211 to limit the abutting portion 1111 from being reset axially into the limiting groove 212.

[0075] It is understandable that due to the setting of the first resisting surface 11112, the distance from the axis of the pressing member 111 to the first resisting surface 11112 is smaller than the distance from the axis to the arc surface, and in order to allow the abutting portion 1111 to rotate in the slide groove 211, the slide groove 211 needs to be set with the distance from the axis of the pressing member 111 to the arc surface as the radius. Therefore, the limiting groove 212 is narrowed relative to the slide groove 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 slide groove 211 and the limiting groove 212 and cannot be reset to the limiting groove 212, thereby avoiding the abutting portion 1111 from being reset to the limiting groove 212 in the folded state of the second connecting member, and the pressing member 111 needs 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 may be a helical compression spring, and its two ends are respectively connected to the pressing member 111 and the second connecting member to realize the pressing and resetting of the pressing member 111. In the 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 in the limiting groove 212. During the rotation of the second connecting member, by pressing the pressing member 111, the elastic member 112 contracts, the abutting portion 1111 enters the sliding groove 211, and 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, so that the abutting portion 1111 is pressed against the wall of the slide groove 211 and cannot be reset into 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, so that the abutting portion 1111 enters the limiting groove 212 and cannot rotate under the restriction of the wall of the limiting groove 212.

[0079] In some embodiments, the folding locking structure 100 further includes a connecting assembly 120, which includes a plug-in 121 and a locking member 122. The plug-in 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 with the plug-in 121 as the axis. The locking member 122 is disposed at one end of the plug-in 121 to limit the plug-in 121 and prevent the plug-in 121 from falling off during rotation.

[0080] Continue reading Fig.10 As shown, in one embodiment, the insertion member 121 can be a bolt, and the locking member 122 can be a nut accordingly. The first connecting portion 210 and the second connecting portion 310 are both provided with corresponding connecting 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, so that the second connecting member can rotate relative to the first connecting member and will not fall off the raised frame during the movement.

[0081] In another embodiment, the insertion member 121 may also be a pin shaft, and limit holes are provided at both ends, and the locking member 122 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 is 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 rotational connection between the second connecting member and the first connecting member, which 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 grooves 214, each friction plate is respectively installed in a corresponding mounting groove 214, and the inserting plug 121 is inserted through each friction plate in sequence.

[0083] Exemplarily, two friction plates and two mounting grooves 214 are provided, and the two friction plates are symmetrically arranged on both sides of the second connecting portion 310. During the installation process, the insert 121 passes through a friction plate, the second connecting member, and another friction plate in sequence, and is fixed to the locking member 122, so that during the rotation of the second connecting member, the friction plate will provide friction to the second connecting member, offset part of the potential energy of the second connecting member during the rotation process, reduce the rotation speed of the second connecting member, and reduce the loss of components.

[0084] The embodiment of the present application further provides a circulation fan 1000, comprising a body assembly 200, a head assembly 300 and a folding locking structure 100 in any of the above embodiments. The folding locking structure 100 is foldably connected between the body assembly 200 and the head assembly 300. By setting the folding locking structure 100, the circulation fan 1000 can be freely folded and stored, which is convenient for storage and reduces the occupied space.

[0085] This embodiment has the folding locking structure 100 in any of the above embodiments, and therefore has all the beneficial effects of the folding locking structure 100 in 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 Fig.11 In some embodiments, a wiring hole 315 is provided on a side of the second connection portion 310 away from the pressing member 111, and a wiring groove 213 and a wire clamping groove 215 are provided on the first connection 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] It is understandable that all electrical equipment needs to be equipped with wiring to achieve electrical connection of internal electronic components. For the overall aesthetics of the equipment, the wiring of the wiring is arranged inside the folding locking structure 100 in the embodiment of the present application to reduce the exposure of external wiring. The wiring passes through the wiring hole 315 of the head assembly 300 and passes through the wiring groove 213 of the body assembly 200, and the wiring is clamped through the wire clamping groove 215 of the body assembly 200.

[0089] Continue reading Fig.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 a 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 part 210, and the upper cover 220 is provided with a clamping block, and the first connecting part 210 is correspondingly provided with a connecting groove to engage with the upper cover 220. In other embodiments, the upper cover 220 and the first connecting part 210 can also be locked with screws, which is not specifically limited here. When the upper cover 220 is installed on the first connecting part 210, the wire retaining rib is correspondingly inserted into the wire clamping groove 215 in the first connecting part 210, thereby limiting the movement of the wiring and preventing interference of the wiring during the rotation of the second connecting member.

[0091] Further, the head assembly 300 includes a second connecting portion 310 and a cover plate 330, and the cover plate 330 is covered 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 be respectively provided with a block and a connecting groove to achieve assembly and cooperation with each other. In other embodiments, the cover plate 330 and the second connecting portion 310 can also be locked with screws, which is not specifically limited here.

[0092] Furthermore, the head 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 a fan blade and a drive motor, and when powered on, the drive motor drives the fan blade to rotate to perform heat dissipation operations. The second connecting portion 310 is a Y-shaped structure, and its bottom end is rotatably connected to the first connecting member. The fan body 320 is installed 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 achieving stable installation of the fan body 320, and during operation, the fan body 320 can rotate relative to the second connecting portion 310 to adjust the operating angle.

[0094] Continue reading Fig.13 and Fig.14 As shown, in some embodiments, the circulation fan 1000 also 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. When the circulation fan 1000 is assembled, the support assembly 400 is locked with the chassis 500, so that the chassis 500 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 support assembly 400 can be separated from the chassis 500 to further reduce the space occupied by the circulation fan 1000.

[0096] 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.

[0097] 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. Therefore, the protection scope of the patent application shall be subject to the attached claims.
