Description

Technical Field

[0001] This utility model relates to mahjong tables, and more particularly to a novel electric folding mechanism for mahjong tables. Background Technology

[0002] Mahjong, as a highly entertaining and social activity, is loved by a wide range of people. This has led to the widespread use of mahjong tables in everyday life settings such as family gatherings, games with friends, and various entertainment venues like card rooms and clubs. To meet the storage needs of different scenarios and facilitate movement, folding mahjong tables have emerged on the market. However, most folding mahjong tables currently available are manually folding types.

[0003] Manually folding mahjong tables (such as the Chinese utility model patent with Chinese patent publication number CN 219813494 U, entitled "A Mahjong Table") have revealed many drawbacks in actual use. Their folding and unfolding processes rely entirely on manual operation by the user, requiring considerable strength and involving cumbersome steps. For people with less strength, such as the elderly, children, or women, completing the entire folding or unfolding action is often extremely difficult, and may even cause physical injury due to improper force.

[0004] Therefore, developing a new type of electric folding mechanism for mahjong tables to solve the problems of laboriousness, cumbersome process, and low efficiency of existing manual folding mahjong tables is of great practical significance. Utility Model Content

[0005] The present invention addresses the aforementioned shortcomings by providing a novel electric folding mechanism for mahjong tables.

[0006] The above-mentioned objective of this utility model is achieved through the following technical solution: a novel electric folding mechanism for a mahjong table, comprising a support base and a flipping assembly. The flipping assembly is connected to the bottom of the mahjong table surface. A flipping base is provided on the top of the support base. The flipping base is U-shaped, and arc-shaped gear teeth are provided on both inner sides. The upper part of the flipping assembly is pivotally / hinged to the upper part of the flipping base, so that the flipping assembly and the table surface connected thereto can rotate around the pivot / hinged point. The lower two sides of the flipping assembly are provided with freely rotatable synchronous gears that mesh with the arc-shaped gear teeth. The synchronous gear on one side of the flipping assembly is driven by a drive motor.

[0007] Furthermore, the flipping assembly includes a first flipping plate and a second flipping plate, with a rotating shaft passing through the first and second flipping plates. Synchronous gears are located at both ends of the rotating shaft. This structural design allows the synchronous gears to be stably mounted on the flipping assembly and to rotate synchronously under the action of the drive motor, thereby causing the first and second flipping plates to flip synchronously, thus ensuring the consistency and stability of the desktop folding and unfolding actions.

[0008] Furthermore, the drive motor is fixed to either the first or second flipping plate. Directly fixing the drive motor to the support plate of the flipping assembly allows for more direct and efficient power transmission, reduces energy loss, and also facilitates motor installation and maintenance.

[0009] Furthermore, the synchronous gear on one side of the flipping assembly is a double gear, comprising a primary gear and a secondary gear. The primary gear meshes with the drive gear on the output shaft of the drive motor, and the secondary gear meshes with the arc-shaped gear on the inner side of the flipping base. By adopting a double gear design, different transmission ratios can be achieved, allowing adjustment of the speed and force of the desktop folding and unfolding according to actual needs, thereby improving the adaptability and flexibility of the mechanism.

[0010] Furthermore, the upper ends of the arc-shaped gear teeth on both sides of the flip base are respectively equipped with an unfolded limit switch and a folded limit switch. When unfolded, the bottom of the mahjong table or the synchronous gear contacts the unfolded limit switch, and the drive motor stops working; when folded, the synchronous gear or the bottom of the table presses against the folded limit switch, and the drive motor stops working. The limit switches can precisely control the folding and unfolding positions of the tabletop, avoiding damage caused by excessive folding or unfolding, and improving the safety and reliability of the mechanism.

[0011] Furthermore, an electrical control box is installed on the flip base, and a folding / unfolding control switch is provided on the surface of the control box. Operators can conveniently control the folding and unfolding of the desktop through the control switch on the electrical control box, realizing convenient and intelligent operation.

[0012] The advantages of this invention compared to existing technologies are as follows: This invention offers significant advantages over manually folding mahjong tables. Manually folding mahjong tables require manual operation, which is laborious, cumbersome, and inefficient. This invention, however, employs a structure design of a flipping assembly and a flipping base. The flipping assembly, through a rotating shaft and synchronous gears passing through the first and second flipping plates, meshes with the arc-shaped gear teeth on the inner side of the flipping base. Driven by a motor, this ensures that the left and right sides of the tabletop remain highly synchronized during folding and unfolding, allowing the tabletop to complete the movement smoothly and preventing tilting. Furthermore, limit switches and an electrical control box switch are included to precisely control the folding and unfolding positions of the tabletop, making operation simple and convenient, and enhancing safety and reliability.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] like Figures 1 to 7 As shown, the electric folding mechanism of a novel mahjong table of this utility model includes a support base 2, a flipping component 3, a flipping base 4, a synchronous gear 5, a drive motor 6, an unfolded limit switch 7, a folded limit switch 8, and an electrical control box 9.

[0022] The flipping assembly 3 is fixedly connected to the bottom of the mahjong tabletop 1, and the top of the support base 2 is provided with a flipping base 4. The flipping base 4 is U-shaped, and both inner sides are provided with arc-shaped gear teeth 10. The upper part of the flipping assembly 3 is connected to the upper part of the flipping base 4 by a pivot / hinged connection, which allows the tabletop 1 to rotate around the pivot / hinged point 304.

[0023] The flipping assembly 3 includes a first flipping plate 301 and a second flipping plate 302, with a through-shaft 303 between them. A synchronous gear 5 is mounted at both ends of the shaft 303, can rotate freely, and meshes with the arcuate gear teeth 10 on the inner side of the flipping base 4. The drive motor 6 is fixed to the first flipping plate 301 or the second flipping plate 302 of the flipping assembly 3. The drive gear 12 on the output shaft of the drive motor 6 meshes with the first-stage gear teeth 501 of the synchronous gear 5, which is a double gear on one side of the flipping assembly 3. The second-stage gear teeth 502 of the double gear mesh with the arcuate gear teeth 10 on the inner side of the flipping base 4.

[0024] The upper ends of the arc-shaped gear teeth 10 on both sides of the flip base 4 are respectively equipped with an unfolded limit switch 7 and a folded limit switch 8. In addition, an electrical control box 9 is provided on the flip base 4, and a folding / unfolding control switch 11 is provided on the surface of the electrical control box 9.

[0025] The working process of this utility model:

[0026] Unfolding Operation: When the mahjong tabletop 1 needs to be unfolded, the operator presses the folding / unfolding control switch 11 on the surface of the control box 9. The drive motor 6 starts, driving the drive gear 12 on its output shaft to rotate. The drive gear 12 meshes with the synchronous gear 5 (the first-stage gear 501 of the double gear), causing the synchronous gear 5 to rotate. Since the synchronous gear 5 meshes with the arc-shaped gear 10 on the inner side of the flip base 4, the rotation of the synchronous gear 5 will drive the flip assembly 3 to move relative to the flip base 4, thereby causing the tabletop 1 to unfold around the pivot / hinged connection point. When the tabletop 1 is fully unfolded, the bottom of the tabletop 1 contacts the unfolding limit switch 7. The unfolding limit switch 7 sends a signal, and the control board inside the control box 9 controls the drive motor 6 to stop working, and the tabletop 1 stops unfolding and remains in the unfolded state.

[0027] Folding Operation: When the mahjong tabletop 1 needs to be folded, the operator presses the folding / unfolding control switch 11 on the surface of the control box 9. The drive motor 6 starts in reverse, driving the drive gear to rotate in the opposite direction. Similarly, through the meshing transmission of the synchronous gear 5 and the arc gear 10, the tabletop 1 folds around the pivot / hinged connection point. When the tabletop 1 is folded to the correct position, the synchronous gear 5 contacts the folding limit switch 8. The folding limit switch 8 sends a signal, and the control board inside the control box 9 controls the drive motor 6 to stop working, and the tabletop 1 stops folding and remains in the folded state.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
