Description

Technical Field

[0001] The utility model relates to the field of clocks, in particular to a flip clock. Background Art

[0002] Flip Clock is a minimalist desktop digital clock.

[0003] China's authorization announcement number CN219831661U discloses a mechanical page-turning clock, including a base plate, on which a minute digit assembly, a control box and an hour digit assembly are installed. The control box is located between the hour digit assembly and the minute digit assembly, and a colon symbol is also provided on the top of the control box. In summary, the utility model adopts a visual mechanical structure, and the user can intuitively understand the principle of the clock rotation. In addition, the mechanical page-turning clock is composed of several groups of mechanical flip calculators, and two groups of stepper motors drive the hour digit components and the minute digit components to operate respectively. As the rotating shaft rotates, the digital components present different digital changes. The overall structural design is ingenious and conforms to the operating laws of the clock. A control box is also provided to adjust the stepper motor to eliminate mechanical errors and achieve the purpose of accurately displaying time. The overall structure is made of metal processing, which is environmentally friendly, wear-resistant and high-temperature resistant, and has a long service life.

[0004] However, this device has the following drawbacks: While it can rotate the digital card by utilizing a rotating cam member in contact with a protrusion on a driven rod, the cam member's contour curve must be machined with high precision. Any errors in this process significantly affect the motion of the driven rod. Furthermore, the contact stress between the cam member and the driven rod is high, resulting in significant wear. This wear worsens with age, potentially causing card flipping to become stuck, incomplete, or impossible, affecting the clock's normal time display. To address these drawbacks, we propose a card flip clock. Utility Model Content

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0031] See also Figure 1-6 The utility model provides a technical solution: a flip clock, comprising: a shell 1, a digital digit structure and a driving structure.

[0032] See Figure 1 and Figure 3 The digital digit structure includes a display board 2, a support rod 3 fixedly mounted on the surface of the display board 2, and a track groove 4 opened on the upper surface of the shell 1 for the support rod 3 to rotate, and the number of display boards 2 is seven, and the seven display boards 2 can form an 8 shape.

[0033] See Figure 2 and Figure 3 The driving structure is arranged inside the housing 1, which includes a gear rack assembly and a power source assembly that can drive the gear rack assembly to work.

[0034] The rack and pinion assembly includes a rotating shaft 5 fixedly mounted on the inner wall of the housing 1, seven spur gears 6 rotatably mounted on the surface of the rotating shaft 5, and a spur rack 7 meshing with the spur gears 6 for transmission. The end of the support rod 3 away from the display board 2 is fixedly connected to the surface of the spur gear 6. When the spur gear 6 rotates, it will drive the support rod 3 to rotate, thereby driving the display board 2 to flip.

[0035] See Figure 3 and Figure 6 The power source assembly includes a telescopic cylinder 8 fixedly mounted on the inner bottom wall of the shell 1, a telescopic rod 9 slidably mounted on the inner wall of the telescopic cylinder 8, a stopper 10 fixedly mounted on the upper end of the telescopic rod 9, an iron block 11 fixedly mounted on the lower end of the telescopic rod 9, and an electromagnet 12 fixedly mounted on the inner bottom wall of the telescopic cylinder 8. The lower surface of the spur rack 7 is fixedly connected to the upper end of the stopper 10. The inner bottom wall of the shell 1 is provided with a single-chip microcomputer 17 that can control the opening and closing time of the electromagnet 12.

[0036] A compression spring 13 is sleeved on the surface of the telescopic cylinder 8 . One end of the compression spring 13 is fixedly connected to the inner bottom wall of the housing 1 , and the other end of the compression spring 13 is fixedly connected to the lower end of the stopper 10 .

[0037] The single-chip microcomputer 17 can independently control the opening and closing of the electromagnet 12 in each telescopic cylinder 8. When the electromagnet 12 is turned on, it can adsorb the iron block 11, thereby driving the spur rack 7 to move downward. The spur rack 7 is engaged with the spur gear 6 to drive the support rod 3 to rotate, and then the display board 2 is driven to rotate. At this time, the compression spring 13 is in a contracted state. When the electromagnet 12 is powered off, the resetting force of the compression spring 13 can drive the telescopic rod 9 to move upward and reset, thereby driving the spur rack 7 and the iron block 11 to reset.

[0038] Compared with the existing technology, the device uses an electromagnet 12 to attract the iron block 11 to drive the spur gear 6 and the spur rack 7 to engage and transmit, and drive the display board 2 to flip, so that it can cooperate with the single-chip microcomputer 17 to drive multiple display boards 2 to flip according to the passage of time, and then change the time letters composed of multiple display boards 2. The spur gear 6 and the spur rack 7 are engaged for transmission, making the transmission more stable and the error smaller, avoiding the problem of jamming.

[0039] See Figure 3-5A groove is provided inside the display board 2, and an LED lamp 14 is fixedly installed inside the groove. A control structure for controlling the opening and closing of the LED lamp 14 is provided between the support rod 3 and the track groove 4. The control structure includes a moving contact 15 fixedly installed on the surface of the support rod 3, and a fixed contact 16 fixedly installed on the inner wall of the track groove 4. The moving contact 15 is electrically connected to the LED lamp 14, and the fixed contact 16 is electrically connected to the external power supply.

[0040] When the support rod 3 rotates until the moving contact 15 contacts the fixed contact 16, the circuit is connected, and the display board 2 is above the shell 1. The external power supply will power the LED light 14, and when the moving contact 15 is disengaged from the fixed contact 16, the LED light 14 will be turned off, and the display board 2 will be behind the shell 1, so that the device can be used to view time at night.

[0041] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited thereto. Any equivalent replacement or change made by a person skilled in the art based on the technical solution and concept of the present invention should be included in the protection scope of the present invention.
