Description

Technical Field

[0001] The present application relates to the field of flip technology, and in particular to a flip structure and an electrical appliance. Background Art

[0002] Floor-mounted electric heaters are typically equipped with a rotating shaft and bracket, allowing for adjustment of the heater's support method for both floor and tabletop use. In related art, when the heater is used on the floor, the rotating shaft is compressed by damping elements such as rubber or silicone to increase friction and thus achieve support. However, with increased use, the damping elements tend to wear out, causing friction to diminish, ultimately rendering them ineffective in supporting the heater, reducing the reliability of the heater's floor support function. Summary of the Invention

[0003] Based on this, it is necessary to provide a flip structure and an electrical appliance to address the problem that the damping member is worn and cannot effectively support the body.

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

[0005] In a first aspect, an embodiment of the present application provides a flip structure, comprising:

[0006] main body;

[0007] a rotating shaft assembly comprising 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 a side of the first rotating shaft facing away from the main body;

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

[0009] Among them, the first bracket can be controlled to drive the first rotating shaft to rotate 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 drive the second rotating shaft to rotate relative to the first rotating shaft to adjust the angle between the first bracket and the second bracket.

[0010] Through the above design, the first bracket can maintain an eight-shaped support for the main body with the second bracket, ensuring that the supporting force of the bracket can always balance the weight of the main body and is not affected by friction attenuation, thereby greatly improving 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, two first rotating shafts are provided, each first rotating shaft being disposed on two opposite sides of the main body, and a second mating portion is provided on a side of each first rotating shaft closer to the main body, the first mating portion being slidably engaged with the second mating portion;

The third abutting surface and the fourth abutting surface are relatively arranged at the two ends of the third mating portion. The 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 the maximum rotation angle during rotation, the boss contacts the third abutting surface and the fourth abutting surface, thereby limiting the rotation angle of the second rotating shaft 122 and limiting the opening angle of the second bracket.

[0023] Through the above design, the first protrusion is locked with the first rotating shaft, and the second protrusion is locked with the second rotating shaft, thereby achieving stable support of 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, a limiting member is provided in the second groove, and the second protrusion is fixedly connected to the limiting member in the second groove via a fastener.

[0028] Through the above design, the connecting member passes through the second rotating shaft and the first rotating shaft in sequence and is locked with the main body to achieve the installation of the rotating shaft assembly and the main body.

[0029] In one embodiment of the first aspect, the flip structure further includes a decorative cover, and the decorative cover is disposed on a side of the second rotating shaft facing away from the first rotating shaft.

[0030] Through the above design, the exposed bolts and holes of the second rotating shaft can be concealed to improve the overall aesthetics.

[0055] See Figure 1 and Figure 2As shown, an embodiment of the present application provides a flip structure 100 that can be used for different support operation modes on the ground and on the desktop. The flip structure 100 includes a main body 110, a rotating shaft assembly 120 and a bracket assembly 130, wherein the main body 110 is an operating component, and the rotating shaft assembly 120 is installed on the main body 110 and can rotate relative to the main body 110. The bracket assembly 130 is connected to the rotating shaft assembly 120, thereby driving the rotating shaft assembly 120 to rotate relative to the main body 110. In this way, when the bracket assembly 130 rotates to above the main body 110, the main body 110 can be placed directly on the desktop for operation; when the bracket assembly 130 rotates to below the main body 110, the main body 110 can be supported by the bracket assembly 130 to meet the needs of placing the main body 110 on the ground for operation, thereby realizing support adjustment of the main body 110 for various operation scenarios.

[0056] It should be noted that the subject 110 of this application is the operating part of a 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 an application scenario.

[0057] Specifically, the shaft assembly 120 includes a first shaft 121 and a second shaft 122. The first shaft 121 is rotatably connected to the main body 110, and the second shaft 122 is rotatably connected to the side of the first shaft 121 facing away from the main body 110. The bracket assembly 130 includes a first bracket 131 and a second bracket 132. The first bracket 131 is fixedly connected to the first shaft 121, and the second bracket 132 is fixedly connected to the second shaft 122. In this way, when the bracket assembly 130 rotates to the bottom of the main body 110, the first bracket 131 and the second bracket 132 can form a cross structure to support the main body 110.

[0058] For example, the first bracket 131 and the second bracket 132 are initially in a closed position. The operator can manipulate the first bracket 131 to drive the first rotating shaft 121 to rotate relative to the main body 110 to adjust the connection angle between the bracket assembly 130 as a whole and the main body 110, thereby adjusting the bracket assembly 130 to be located above or below the main body 110, achieving support adjustment for different working scenarios. When the bracket assembly 130 is rotated to the bottom of the main body 110, the operator can further manipulate the second bracket 132 to drive the second rotating shaft 122 to rotate relative to the first rotating shaft 121 to adjust the angle between the first bracket 131 and the second bracket 132, thereby opening the second bracket 132 and the first bracket 131 to form a triangular support structure for the main body 110. In this way, the limiting structure of the first rotating shaft 121 and the second rotating shaft 122 limits the flipping angle of the first bracket 131 and the second bracket 132, so that the first bracket 131 and the second bracket 132 always maintain an eight-shaped support body 110, ensuring that the supporting force of the bracket can always balance the weight of the body 110 and is not affected by the attenuation of friction, thereby greatly improving the reliability of the ground use function of the electric heater.

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

[0060] Specifically, a first mating portion 111 is provided on each of the left and right sides of the main body 110, and the two first mating portions 111 are symmetrically distributed along the centerline of the main body 110. Accordingly, the rotating shaft assembly 120 includes two first rotating shafts 121 disposed opposite each other, each of which is provided with a second mating portion 1211. Thus, the second mating portion 1211 protrudes from the surface of the first rotating shaft 121. Therefore, during the installation process of the first rotating shaft 121, the second mating portion 1211 is placed within the first mating portion 111, allowing the second mating portion 1211 to rotate and slide within the first mating portion 111, thereby enabling the first rotating shaft 121 to rotate relative to the main body 110. The contact friction between the first rotating shaft 121 and the main body 110 is reduced, thereby improving the service life of the first rotating shaft 121.

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

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

[0063] In another embodiment, one of the two first engaging portions 111 of the main body 110 may be a boss and the other a stop slot. Accordingly, the second engaging portion 1211 of one first rotating shaft 121 may be a stop slot, while the second engaging portion 1211 of the other first rotating shaft 121 may be a boss, so that the two first rotating shafts 121 are rotatably engaged with the two sides of the main body 110, respectively.

[0064] Furthermore, the first matching portion 111 is a limiting groove and has a first abutting surface 112 and a second abutting surface 113. The first abutting surface 112 and the second abutting surface 113 are relatively arranged at the two ends of the first matching portion 111. The angle between the first abutting surface 112 and the second abutting surface 113 is α, and satisfies 180°≤α≤270°.

[0065] It can be understood that the first matching portion 111 is an incomplete circular groove body. Due to the restriction of the first abutting surface 112 and the second abutting surface 113, when the second matching portion 1211 reaches the maximum rotation angle during the rotation process, the second matching portion 1211 contacts the first abutting surface 112 and the second abutting surface 113, thereby limiting the rotation angle of the first rotating shaft 121, which facilitates the precise positioning of the bracket.

[0066] For example, the 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 support downward and be stored upward. When the second matching portion 1211 contacts 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 matching portion 1211 contacts 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 matching portion 1212 is provided on the side of the first rotating shaft 121 away from the main body 110, and a fourth matching portion 1221 is provided on the side of the second rotating shaft 122 close to the first rotating shaft 121, and the fourth matching portion 1221 is slidably matched with the third matching portion 1212.

[0068] Specifically, two second rotating shafts 122 are provided, each of which has a fourth mating portion 1221 on one side thereof connected to a corresponding first rotating shaft 121. The fourth mating portion 1221 protrudes from the surface of the second rotating shaft 122. Therefore, during the installation process of the second rotating shaft 122, the fourth mating portion 1221 is placed within the third mating portion 1212, allowing the fourth mating portion 1221 to rotate and slide within the third mating portion 1212, thereby enabling the second rotating shaft 122 to rotate relative to the first rotating shaft 121. The contact friction between the second rotating shaft 122 and the first rotating shaft 121 is reduced, thereby improving the service life of the second rotating shaft 122.

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

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

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

[0072] Furthermore, the third matching portion 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 relatively arranged at the two ends of the third matching portion 1212. The angle between the third abutting surface 1215 and the fourth abutting surface 1216 is β, and satisfies 90°≤β≤150°.

[0073] It can be understood that the third matching portion 1212 is an arc-shaped groove structure, thereby forming a third abutment surface 1215 and a fourth abutment surface 1216 at both ends. When the fourth matching portion 1221 reaches the maximum rotation angle during the rotation process, the fourth matching portion 1221 contacts the third abutment surface 1215 and the fourth abutment surface 1216, thereby limiting the rotation angle of the second rotating shaft 122 and limiting the opening angle of the second bracket 132.

[0074] Exemplarily, the angle β between the third abutting surface 1215 and the fourth abutting surface 1216 can be 90°, 100°, 110°, 120°, 130°, 140°, 150°, etc., and can be reasonably selected according to actual needs, as long as the second bracket 132 can support downward and be stored upward. When the fourth matching portion 1221 contacts the third abutting surface 1215, the second bracket 132 is located below the main body 110 and is in an inclined support state, forming an "eight" support structure with the first bracket 131. When the fourth matching portion 1221 contacts the fourth abutting surface 1216, under the restriction of the third matching portion 1212, the second bracket 132 is located above the main body 110 and is parallel to the direction of gravity, thereby being stored above the main body 110 together 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. The first protrusion 1311 is inserted into the first connecting hole 1213 and is fixedly connected to the first rotating shaft 121 via a fastener. 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. The second protrusion 1321 is inserted into the second connecting hole 1222 and is fixedly connected to the second rotating shaft 122 via a fastener.

[0076] Specifically, the two ends of the first bracket 131 are respectively connected to the two first rotating shafts 121, and the two ends of the second bracket 132 are respectively connected to the two second rotating shafts 122. Therefore, when the first bracket 131 and the second bracket 132 are located below the main body 110, the main body 110 is supported by the expansion of the first bracket 131 and the second bracket 132. It can be understood that the size of the second bracket 132 is slightly larger than the first bracket 131 so that when stored, the first bracket 131 can be accommodated within the second bracket 132, thereby reducing the space occupied after storage.

[0077] During assembly, the two ends of the first bracket 131 are respectively extended into the first rotating shaft 121 through the corresponding first connecting holes 1213, and the first protrusion 1311 is aligned with the side of the first rotating shaft 121 facing away from the main body 110, so that the operator can externally bolt the first protrusion 1311 to the first rotating shaft 121. Simultaneously, the two ends of the second bracket 132 are respectively extended into the second rotating shaft 122 through the corresponding second connecting holes 1222, and the second protrusion 1321 is aligned with the side of the second rotating shaft 122 facing away from the first rotating shaft 121, so that the operator can externally bolt the second protrusion 1321 to the second rotating shaft 122. Finally, the first rotating shaft 121 and the second rotating shaft 122 are sequentially installed on the main body 110 to ensure the support and stability of the main body 110.

[0078] See Figure 5 As shown, in one embodiment, a first groove 1214 is provided on the side of the first rotating shaft 121 away from the main body 110 , a limiting piece is provided in the first groove 1214 , and the first protrusion 1311 is fixedly connected to the limiting piece in the first groove 1214 via a fastener.

[0079] See Figure 9 As shown, in another embodiment, a second groove 1223 is defined on the side of the second rotating shaft 122 away from the first rotating shaft 121 , a limiting member is defined in the second groove 1223 , and the second protrusion 1321 is fixedly connected to the limiting member in the second groove 1223 via a fastener.

[0080] In another embodiment, a first groove 1214 is provided on the side of the first rotating shaft 121 facing away from the main body 110, and a second groove 1223 is provided on the side of the second rotating shaft 122 facing away from the first rotating shaft 121. Limiting members are provided in the first groove 1214 and the second groove 1223. The first protrusion 1311 is fixedly connected to the limiting member in the first groove 1214 by a fastener, and the second protrusion 1321 is fixedly connected to the limiting member in the second groove 1223 by a fastener.

[0081] Illustratively, the fasteners in the above embodiments may be bolts or connecting pins, and may be locked by nuts or bayonets accordingly.

[0082] Specifically, the stopper has the same shape as the first groove 1214 and the second groove 1223. When assembling the first bracket 131, the stopper is inserted into the first groove 1214, and then bolts are passed through the stopper, the first rotating shaft 121, and the first bracket 131 in sequence before being tightened.
