Description

Technical Field

[0001] This application relates to the field of flipping technology, and in particular to a flipping structure and electrical appliance. Background Technology

[0002] Versatile electric heaters typically come equipped with a rotating shaft and a stand to adjust the heater's support method for different usage scenarios: floor and tabletop. In related technologies, when the heater is used on the floor, the rotating shaft is pressed together by damping components such as rubber or silicone parts to increase friction and thus support the unit. However, with repeated use, these damping components are prone to wear, leading to a decrease in friction and ultimately, the heater can no longer effectively support the unit, reducing the reliability of its floor-support function. Utility Model Content

[0003] Therefore, it is necessary to provide a flipping structure and electrical components to address the problem that the wear of damping components cannot effectively support the machine body.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0005] In a first aspect, embodiments of this application provide a flipping structure, including:

[0006] main body;

[0007] A rotating shaft assembly includes a first rotating shaft and a second rotating shaft, wherein the first rotating shaft is rotatably connected to the main body, and the second rotating shaft is rotatably connected to the side of the first rotating shaft opposite to the main body;

[0008] A support assembly includes a first support and a second support, wherein the first support is fixedly connected to the first rotating shaft, and the second support is fixedly connected to the second rotating shaft;

[0009] The first bracket can be controlled to rotate the first rotating shaft relative to the main body to adjust the connection angle between the bracket assembly and the main body, and the second bracket can be controlled to rotate the second rotating shaft relative to the first rotating shaft to adjust the included angle between the first bracket and the second bracket.

[0010] Through the above design, the first bracket and the second bracket can maintain a figure-eight support for the main body, ensuring that the supporting force of the bracket can always balance the weight of the main body and is not affected by frictional attenuation, which greatly improves the reliability of the device's ground use function.

[0011] In one embodiment of the first aspect, first mating portions are symmetrically provided on both sides of the main body, and two first rotating shafts are provided, each first rotating shaft being disposed opposite to each other on two opposite sides of the main body. A second mating portion is provided on the side of each first rotating shaft closer to the main body, and the first mating portion and the second mating portion are slidably engaged.

[0012] One of the first mating part and the second mating part is a limiting groove, and the other is a corresponding boss.

[0013] Through the above design, the contact friction between the first rotating shaft and the main body is reduced, thereby increasing the service life of the first rotating shaft.

[0014] In one embodiment of the first aspect, the first mating part is a limiting groove and has a first abutting surface and a second abutting surface. The first abutting surface and the second abutting surface are disposed opposite to each other at both ends of the first mating part. The included angle between the first abutting surface and the second abutting surface is α, and satisfies 180°≤α≤270°.

[0015] With the above design, when the boss reaches its maximum rotation angle during rotation, the boss abuts against the first abutment surface and the second abutment surface, thereby limiting the rotation angle of the first rotating shaft and facilitating the precise positioning of the bracket.

[0016] In one embodiment of the first aspect, a third mating part is provided on the side of the first rotating shaft away from the main body, and a fourth mating part is provided on the side of the second rotating shaft close to the first rotating shaft, wherein the third mating part and the fourth mating part are slidably mated.

[0017] One of the third mating parts and the fourth mating part is a limiting groove, and the other is a corresponding boss.

[0018] Through the above design, the contact friction between the second rotating shaft and the first rotating shaft is reduced, thereby increasing the service life of the second rotating shaft.

[0019] In one embodiment of the first aspect, the third mating part is a limiting groove and has a third abutting surface and a fourth abutting surface. The third abutting surface and the fourth abutting surface are disposed opposite to each other at both ends of the third mating part. The included angle between the third abutting surface and the fourth abutting surface is β, and satisfies 90°≤β≤150°.

[0020] With the above design, when the boss reaches its maximum rotation angle during rotation, the boss abuts against the third and fourth abutment surfaces, thereby limiting the rotation angle of the second rotating shaft 122 and limiting the opening angle of the second bracket.

[0021] In one embodiment of the first aspect, the first bracket has a U-shaped structure and is provided with a first protrusion at both ends. The first rotating shaft is provided with a first connecting hole, the first protrusion passes through the first connecting hole, and is fixedly connected to the first rotating shaft by fasteners.

[0022] The second bracket has a U-shaped structure and is provided with a second protrusion at both ends. The second rotating shaft has a second connecting hole, the second protrusion passes through the second connecting hole, and is fixedly connected to the second rotating shaft by fasteners.

[0023] Through the above design, the first protrusion is locked to the first rotating shaft, and the second protrusion is locked to the second rotating shaft, thereby achieving stable support for the main body.

[0024] In one embodiment of the first aspect, the first rotating shaft is provided with a first groove, a limiting member is provided in the first groove, and the first protrusion is fixedly connected to the limiting member in the first groove by the fastener.

[0025] And / or, the second rotating shaft is provided with a second groove, and a limiting member is provided in the second groove. The second protrusion is fixedly connected to the limiting member in the second groove by a fastener.

[0026] The above design ensures stable installation of the first and second supports and enhances their support strength.

[0027] In one embodiment of the first aspect, the flipping structure further includes a connector that passes through the second pivot and the first pivot in sequence and is then connected to the main body.

[0028] With the above design, the connector passes through the second rotating shaft and the first rotating shaft in sequence and is then locked to the main body to realize the installation of the rotating shaft assembly and the main body.

[0029] In one embodiment of the first aspect, the flipping structure further includes a decorative cover disposed on the side of the second pivot opposite to the first pivot.

[0030] The above design can conceal the exposed bolts and holes of the second shaft, thereby improving the overall aesthetics.

[0031] Secondly, embodiments of this application also provide an electrical appliance, including the flipping structure described in any of the above embodiments.

[0032] Through the above design, the heating equipment can be adjusted to various operating scenarios and the reliability of the ground use function of the heating equipment can be improved.

[0033] In one embodiment of the second aspect, the electrical appliance includes at least one of an air outlet device, a heating device, an air purification device, or a humidification device.

[0034] In one embodiment of the second aspect, the electrical appliance is one of a fan, an electric heater, an air purifier, and a humidifier.

[0035] Compared to related technologies, the beneficial effects of this application are as follows: This application provides a flipping structure and an electrical appliance. The flipping structure includes a main body, a rotating shaft assembly, and a support assembly.

The first rotating shaft is rotatably connected to the main body, the second rotating shaft is rotatably connected to the first rotating shaft, the first support is fixedly connected to the first rotating shaft, and the second support is fixedly connected to the second rotating shaft. In this way, when the electric heater needs to be placed on the ground, the entire support assembly is rotated to below the main body, and the second support is driven to rotate relative to the first support, forming a supporting angle between the first and second supports, thus achieving stable ground support for the electric heater and ensuring the balanced support of the main body.

[0049] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the first connotation of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0050] In the description of this application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "first", "second", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0051] Secondly, where the term "and / or" appears, "and / or" merely describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Furthermore, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship. Where the terms "first" and "second" appear, these terms are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0052] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the connection of the first parts of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0053] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0054] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, 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 possible implementation.

[0055] See Figure 1 and Figure 2As shown, an embodiment of this application provides a flip structure 100, which can be used for different support operation modes on the ground and on a table. The flip structure 100 includes a main body 110, a pivot assembly 120, and a support assembly 130. The main body 110 is the working component, and the pivot assembly 120 is mounted on the main body 110 and can rotate relative to the main body 110. The support assembly 130 is connected to the pivot assembly 120, thereby driving the pivot assembly 120 to rotate relative to the main body 110. Thus, when the support assembly 130 rotates above the main body 110, the main body 110 can be directly placed on a table for operation; when the support assembly 130 rotates below the main body 110, it can support the main body 110 to meet the needs of placing the main body 110 on the ground for operation, thereby realizing the support adjustment of the main body 110 for various operation scenarios.

[0056] It should be noted that the main body 110 of this application is the working part of the device that needs to support the operation, such as a fan, a heater, etc. For ease of understanding, this application uses a heater as an example of the application scenario.

[0057] Specifically, the pivot assembly 120 includes a first pivot 121 and a second pivot 122. The first pivot 121 is rotatably connected to the main body 110, and the second pivot 122 is rotatably connected to the side of the first pivot 121 opposite to the main body 110. The support assembly 130 includes a first support 131 and a second support 132. The first support 131 is fixedly connected to the first pivot 121, and the second support 132 is fixedly connected to the second pivot 122. Thus, when the support assembly 130 rotates to a position below the main body 110, the first support 131 and the second support 132 can support the main body 110 in a cross-shaped structure.

[0058] For example, the first support 131 and the second support 132 are initially in a closed position. The operator can manipulate the first support 131 to drive the first rotating shaft 121 to rotate relative to the main body 110, thereby adjusting the connection angle between the support assembly 130 and the main body 110, and thus adjusting the position of the support assembly 130 above or below the main body 110 to achieve support adjustment for different working scenarios. When the support assembly 130 is rotated to below the main body 110, the operator can further manipulate the second support 132 to drive the second rotating shaft 122 to rotate relative to the first rotating shaft 121, thereby adjusting the angle between the first support 131 and the second support 132, so that the second support 132 and the first support 131 are in an open state, forming a triangular support structure for the main body 110. Thus, by limiting the rotation angle of the first support 131 and the second support 132 through the limiting structure of the first rotating shaft 121 and the second rotating shaft 122, the first support 131 and the second support 132 always maintain the figure-eight support body 110, ensuring that the supporting force of the support can always balance the weight of the body 110 and is not affected by the attenuation of friction, which greatly improves the reliability of the electric heater's floor use function.

[0059] Continue reading Figure 3 and Figure 4 As shown, in some embodiments, the main body 110 has symmetrically provided first mating portions 111 on both sides, and two first rotating shafts 121 are provided, each first rotating shaft 121 being disposed opposite to each other on two opposite sides of the main body 110. Each first rotating shaft 121 has a second mating portion 1211 on the side closer to the main body 110, and the second mating portion 1211 is slidably engaged with the first mating portion 111. One of the first mating portion 111 and the second mating portion 1211 is a limiting groove, and the other is a corresponding boss.

[0060] Specifically, a first mating part 111 is provided on each of the left and right sides of the main body 110, and the two first mating parts 111 are symmetrically distributed along the center line of the main body 110. Correspondingly, the rotating shaft assembly 120 includes two first rotating shafts 121 arranged opposite each other, and each first rotating shaft 121 is provided with a second mating part 1211. Thus, the second mating part 1211 protrudes from the surface of the first rotating shaft 121, so that during the installation of the first rotating shaft 121, the second mating part 1211 is placed in the first mating part 111, so that the second mating part 1211 can rotate and slide within the first mating part 111, thereby allowing the first rotating shaft 121 to rotate relative to the main body 110, and reducing the contact friction between the first rotating shaft 121 and the main body 110, thus improving the service life of the first rotating shaft 121.

[0061] In one embodiment, the two first mating parts 111 of the main body 110 are both limiting grooves, and correspondingly, the second mating parts 1211 of the two first rotating shafts 121 are both bosses.

[0062] In another embodiment, both first mating parts 111 of the main body 110 are bosses, and correspondingly, the second mating parts 1211 of the two first rotating shafts 121 are limiting grooves.

[0063] In another embodiment, one of the two first mating portions 111 of the main body 110 can be a boss and the other can be a limiting groove. Correspondingly, the second mating portion 1211 of one first rotating shaft 121 is a limiting groove, and the second mating portion 1211 of the other first rotating shaft 121 is a boss, so that the two first rotating shafts 121 are respectively rotatably mated with the two sides of the main body 110.

[0064] Furthermore, the first mating part 111 is a limiting groove and has a first abutting surface 112 and abutting surface 113. The first abutting surface 112 and the second abutting surface 113 are disposed opposite to each other at both ends of the first mating part 111. The included angle between the first abutting surface 112 and the second abutting surface 113 is α, and satisfies 180°≤α≤270°.

[0065] Understandably, the first mating part 111 is a non-complete circular groove. Due to the restriction of the first abutting surface 112 and the second abutting surface 113, when the second mating part 1211 reaches its maximum rotation angle during rotation, the second mating part 1211 abuts against the first abutting surface 112 and the second abutting surface 113, thereby limiting the rotation angle of the first rotating shaft 121 and facilitating the precise positioning of the bracket.

[0066] For example, the included angle α between the first abutting surface 112 and the second abutting surface 113 can be 180°, 190°, 200°, 210°, 220°, 230°, 240°, 250°, 260°, 270°, etc., and can be reasonably selected according to actual needs, as long as the first bracket 131 can be supported downwards and stored upwards. When the second mating part 1211 abuts against the first abutting surface 112, the first bracket 131 is located below the main body 110 and is in an inclined supporting state. When the second mating part 1211 abuts against the second abutting surface 113, the first bracket 131 is located above the main body 110 and is parallel to the direction of gravity, thereby facilitating the storage of the bracket assembly 130.

[0067] Continue reading Figure 5 and Figure 6 As shown, in some embodiments, a third mating part 1212 is provided on the side of the first rotating shaft 121 away from the main body 110, and a fourth mating part 1221 is provided on the side of the second rotating shaft 122 close to the first rotating shaft 121. The fourth mating part 1221 and the third mating part 1212 are in sliding engagement.

[0068] Specifically, two identical second rotating shafts 122 are provided, and each second rotating shaft 122 has a fourth mating part 1221 on one side that connects to a corresponding first rotating shaft 121. The fourth mating part 1221 protrudes from the surface of the second rotating shaft 122, so that during the installation of the second rotating shaft 122, the fourth mating part 1221 is placed inside the third mating part 1212, allowing the fourth mating part 1221 to rotate and slide within the third mating part 1212. This enables the second rotating shaft 122 to rotate relative to the first rotating shaft 121, and reduces the contact friction between the second rotating shaft 122 and the first rotating shaft 121, thereby improving the service life of the second rotating shaft 122.

[0069] In one embodiment, the third mating portion 1212 of the two first rotating shafts 121 are both limiting grooves, and correspondingly, the fourth mating portion 1221 of the two second rotating shafts 122 are both bosses.

[0070] In another embodiment, the third mating portion 1212 of the two first rotating shafts 121 are both bosses, and correspondingly, the fourth mating portion 1221 of the two second rotating shafts 122 are both limiting grooves.

[0071] In another embodiment, the third mating portion 1212 of one first rotating shaft 121 is a boss, and the third mating portion 1212 of the other first rotating shaft 121 is a limiting groove. Correspondingly, the fourth mating portion 1221 of one second rotating shaft 122 is a limiting groove, and the fourth mating portion 1221 of the other second rotating shaft 122 is a boss, so that the two second rotating shafts 122 respectively rotate and engage with the corresponding first rotating shaft 121.

[0072] Furthermore, the third mating part 1212 is a limiting groove and has a third abutting surface 1215 and a fourth abutting surface 1216. The third abutting surface 1215 and the fourth abutting surface 1216 are disposed opposite to each other at both ends of the third mating part 1212. The included angle between the third abutting surface 1215 and the fourth abutting surface 1216 is β, and satisfies 90°≤β≤150°.

[0073] Understandably, the third mating part 1212 has an arc-shaped groove structure, thereby forming a third abutment surface 1215 and a fourth abutment surface 1216 at both ends to restrict the rotation angle. When the fourth mating part 1221 reaches its maximum rotation angle during rotation, the fourth mating part 1221 abuts against the third abutment surface 1215 and the fourth abutment surface 1216, thereby restricting the rotation angle of the second rotating shaft 122 and restricting the opening angle of the second support 132.

[0074] For example, the included angle β between the third abutment surface 1215 and the fourth abutment surface 1216 can be 90°, 100°, 110°, 120°, 130°, 140°, 150°, etc., and can be reasonably selected according to actual needs, as long as it can satisfy the downward support and upward storage of the second bracket 132. When the fourth mating part 1221 abuts against the third abutment surface 1215, the second bracket 132 is located below the main body 110 and is in an inclined support state, forming a V-shaped support structure with the first bracket 131. When the fourth mating part 1221 abuts against the fourth abutment surface 1216, under the restriction of the third mating part 1212, the second bracket 132 is located above the main body 110 and parallel to the direction of gravity, thus being stored above the main body 110 along with the first bracket 131.

[0075] Continue reading Figure 7 and Figure 8 As shown, in some embodiments, the first bracket 131 has a U-shaped structure and is provided with a first protrusion 1311 at both ends. The first rotating shaft 121 has a first connecting hole 1213, and the first protrusion 1311 passes through the first connecting hole 1213 and is fixedly connected to the first rotating shaft 121 by fasteners. The second bracket 132 has a U-shaped structure and is provided with a second protrusion 1321 at both ends. The second rotating shaft 122 has a second connecting hole 1222, and the second protrusion 1321 passes through the second connecting hole 1222 and is fixedly connected to the second rotating shaft 122 by fasteners.

[0076] Specifically, the two ends of the first bracket 131 are connected to the two first rotating shafts 121, and the two ends of the second bracket 132 are connected to the two second rotating shafts 122. Thus, when the first bracket 131 and the second bracket 132 are located below the main body 110, the opening of the first bracket 131 and the second bracket 132 provides support for the main body 110. It is understood that the second bracket 132 is slightly larger than the first bracket 131 so that the first bracket 131 can be accommodated within the second bracket 132 during storage, thereby reducing the space occupied after storage.

[0077] During assembly, both ends of the first bracket 131 are inserted into the first rotating shaft 121 through the corresponding first connecting holes 1213, and the first protrusion 1311 is attached to the side of the first rotating shaft 121 away from the main body 110, so that the operator can lock the first protrusion 1311 to the first rotating shaft 121 from the outside with bolts. At the same time, both ends of the second bracket 132 are inserted into the second rotating shaft 122 through the corresponding second connecting holes 1222, and the second protrusion 1321 is attached to the side of the second rotating shaft 122 away from the first rotating shaft 121, so that the operator can lock the second protrusion 1321 to the second rotating shaft 122 from the outside with bolts. Finally, the first rotating shaft 121 and the second rotating shaft 122 are installed on the main body 110 in sequence to achieve stable support for the main body 110.

[0078] See Figure 5 As shown, in one embodiment, the first rotating shaft 121 has a first groove 1214 on the side opposite to the main body 110, and a limiting member is provided in the first groove 1214. The first protrusion 1311 is fixedly connected to the limiting member in the first groove 1214 by fasteners.

[0079] See Figure 9 As shown, in another embodiment, the second rotating shaft 122 has a second groove 1223 on the side opposite to the first rotating shaft 121, and a limiting member is provided in the second groove 1223. The second protrusion 1321 is fixedly connected to the limiting member in the second groove 1223 by fasteners.

[0080] In another embodiment, the first rotating shaft 121 has a first groove 1214 on the side opposite to the main body 110, and the second rotating shaft 122 has a second groove 1223 on the side opposite to the first rotating shaft 121. Both the first groove 1214 and the second groove 1223 are provided with limiting members. The first protrusion 1311 is fixedly connected to the limiting member in the first groove 1214 by fasteners, and the second protrusion 1321 is fixedly connected to the limiting member in the second groove 1223 by fasteners.

[0081] For example, the fasteners in the above embodiments can all be one of bolts or connecting pins, and are locked by nuts or locking pins accordingly.

[0082] Specifically, the limiting member has the same shape as the first groove 1214 and the second groove 1223. When assembling the first bracket 131, the limiting member is embedded in the first groove 1214, and then bolts are passed through the limiting member, the first rotating shaft 121, and the first bracket 131 in sequence and then locked. When assembling the second bracket 132, the limiting member is embedded in the second groove 1223, and then bolts are passed through the limiting member, the second rotating shaft 122, and the second bracket 132 in sequence and then locked, so as to achieve stable installation of the first bracket 131 and the second bracket 132 and improve the support strength.

[0083] In some embodiments, the flip structure 100 further includes a connector, which passes through the second rotating shaft 122 and the first rotating shaft 121 in sequence and is then connected to the main body 110.

[0084] For example, the connector may be a pin or a bolt, through which the second rotating shaft 122 and the first rotating shaft 121 are sequentially passed and locked to the main body 110, so as to realize the installation of the rotating shaft assembly 120 and the main body 110.

[0085] Of course, in other embodiments, the first rotating shaft 121 can be assembled with the main body 110 and the second rotating shaft 122 can be assembled with the first rotating shaft 121 through the slot cooperation. Both can realize the installation of the rotating shaft assembly 120 with the main body 110 and enable the rotating shaft assembly 120 to rotate relative to the main body 110.

[0086] Continue reading Figure 10 As shown, in some embodiments, the flip structure 100 further includes a decorative cover 140, which covers the side of the second pivot 122 opposite to the first pivot 121.

[0087] Specifically, the second rotating shaft 122 has multiple snap-fit ​​holes 1224 on the side opposite to the first rotating shaft 121, and the decorative cover 140 has multiple snap-fit ​​posts 141 on one side. The snap-fit ​​posts 141 engage with the snap-fit ​​holes 1224 to install the decorative cover 140 onto the second rotating shaft 122. The decorative cover 140 conceals the exposed bolts and holes of the second rotating shaft 122, improving the overall aesthetics. Furthermore, the decorative cover 140 can be the same color or pattern as the main body 110, unifying the overall appearance and further enhancing the aesthetic appeal.
