Description

Technical Field

[0001] The present application relates to the technical field of pendulum clock models, and in particular to an interactive pendulum clock model with adjustable pendulum length. Background Art

[0002] A pendulum clock is a clock invented in 1657. It is manufactured according to the law of simple pendulum and uses a pendulum to control other parts to make the clock run at a uniform speed. It can usually tell the time. A spring is used to provide energy to make it swing.

[0003] A swinging pendulum swings by converting gravitational potential energy into kinetic energy. Simply put, if you pull the pendulum up, it will swing down due to the influence of gravity, and after reaching the lowest position, it has a speed and it is impossible for it to stop there directly. Due to inertia, it will continue to rush through the lowest position, and when it swings to the highest position, it swings back because gravity slows it down to zero, and at this time the pendulum still has downward acceleration, and it swings back and forth continuously.

[0004] At present, most of the pendulum clock models on the market cannot adjust the pendulum length, and the demonstration is boring and tedious. They rely entirely on a single structure and have poor display effects. Utility Model Content

[0005] The present application proposes an interactive pendulum clock model with adjustable pendulum length to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, this application adopts the following technical solutions:

[0007] An interactive pendulum clock model with adjustable pendulum length comprises a pendulum clock body, a concave clock dial is provided at the front center of the pendulum clock body, a rotating shaft is provided through the center of the pendulum clock body, one end of the rotating shaft extends into the concave clock dial and is fixedly installed with a pendulum rod, a pendulum is sleeved on the outer side of the pendulum rod, a pendulum length adjustment mechanism matched with the pendulum rod is provided on the inner side of the pendulum, a digital tube is provided above the rotating shaft, a cartoon figure pop-up mechanism is provided on the top of the digital tube, a circular groove is provided at the rear center of the pendulum clock body, and a pendulum limiting mechanism is provided on the inner side of the circular groove.

[0008] By adopting the above technical solution, the pendulum length adjustment mechanism can be responsible for the height of the pendulum on the pendulum rod, thereby adjusting the pendulum length. The pendulum that can move up and down can guide the audience to actively adjust the position of the pendulum and observe the time it takes for the pendulum to swing back and forth once. The time will be synchronously displayed on the digital tube, which is convenient for the audience to watch and understand intuitively. In order to increase the fun of the exhibits, a cartoon man pop-up mechanism is set. When the pendulum swings back and forth for exactly one second, a cartoon man with a thumbs up will pop up. At the same time, the pendulum limiting mechanism can effectively limit the swinging area of ​​the pendulum. The display is carried out in the form of model interaction combined with mechanical demonstration, which improves the display effect.

[0009] As a preferred embodiment, the pendulum length adjustment mechanism includes a notch opened on one side of the pendulum, and a wedge-shaped rubber block and a pressing block are provided on the inner side of the notch. One side of the inclined surface of the wedge-shaped rubber block is in conflict with the pressing block, and the other side is in conflict with the outer side of the pendulum rod. A return spring is connected between the bottom of the pressing block and the inner wall of the notch.

[0010] By adopting the above technical solution, the pressing block is squeezed downward, the pressing block moves downward and drives the return spring to compress, and then the wedge-shaped rubber block loses the squeezing of the pressing block and no longer maintains close contact with the outer wall of the pendulum rod. At this time, the pendulum can be dragged and moved along the length direction of the pendulum rod to complete the adjustment of the pendulum length.

[0011] As a preferred embodiment, the cartoon figure pop-up mechanism includes a pop-up groove, gear grooves are provided on the inner walls on both sides of the pop-up groove, and a driving motor is provided on the inner bottom of the gear groove.

A sliding groove compatible with the slider is provided on the inner bottom of the pop-up groove, and windows are hinged on both sides of the front end of the pop-up groove, and the windows are movably connected to the double-sided rack through a connecting rod.

[0012] By adopting the above technical solution, the driving motor is responsible for driving the gear to rotate, the gear then drives the double-sided rack to move, the double-sided rack then drives the cartoon man to pop out forward, and at the same time the double-sided rack pushes the window open through the connecting rod, which effectively increases the interest of the exhibits, and the slider and the slide groove cooperate to ensure that the cartoon man moves smoothly.

[0013] As a preferred embodiment, the pendulum limiting mechanism includes an auxiliary rocker arm, which is fixedly connected to the rear end of the rotating shaft, and an arc-shaped limiting track is provided at the lower end of the circular groove. The end of the auxiliary rocker arm is rotatably connected to a roller, and the roller is adapted to the arc-shaped limiting track.

[0014] By adopting the above technical solution, during the movement of the swing arm, the auxiliary swing arm and the swing arm keep swinging synchronously, so the swing arm can be limited by limiting the auxiliary swing arm through the arc-shaped limiting track, and the rolling of the roller in the arc-shaped limiting track can reduce friction resistance.

[0015] As a preferred embodiment, a single-chip microcomputer is provided inside the pendulum clock body, the output end of the digital tube is electrically connected to the input end of the single-chip microcomputer, and the output end of the single-chip microcomputer is electrically connected to the input end of the driving motor.

[0016] By adopting the above technical solution, in order to increase the interest of the exhibits, when the pendulum swings back and forth for exactly one second, the single-chip microcomputer starts the drive motor, and the drive motor drives the gear to engage with the double-sided rack, thereby achieving the purpose of popping out the cartoon character.

[0017] As a preferred embodiment, the inner wall of the concave clock dial is provided with time modification scales distributed in a fan shape along the circumferential direction, and the time modification scales are made of UV printing material.

The time will be synchronously displayed on the digital tube 7, which is convenient for the audience to watch and understand intuitively. In order to increase the fun of the exhibits, a cartoon man pop-up mechanism 8 is set. When the pendulum swings back and forth for exactly one second, a cartoon man 85 with a thumbs up will pop up. At the same time, the pendulum limiting mechanism 10 can effectively limit the swinging area of ​​the pendulum 5. The display is carried out in the form of model interaction combined with mechanical demonstration, which improves the display effect.

[0029] Reference Figure 2 and Figure 4The pendulum length adjustment mechanism 6 includes a notch 61 opened on one side of the pendulum 5, and a wedge-shaped rubber block 62 and a pressing block 63 are provided on the inner side of the notch 61. One side of the inclined surface of the wedge-shaped rubber block 62 conflicts with the pressing block 63, and the other side conflicts with the outer side of the pendulum rod 4. A return spring 64 is connected between the bottom of the pressing block 63 and the inner wall of the notch 61, which presses the pressing block 63 downward. The pressing block 63 moves downward and drives the return spring 64 to be compressed. Then the wedge-shaped rubber block 62 loses the squeezing of the pressing block 63 and no longer maintains close contact with the outer wall of the pendulum rod 4. At this time, the pendulum 5 can be dragged to move along the length direction of the pendulum rod 4, thereby completing the pendulum length adjustment.

The driving motor is responsible for driving the gear 83 to rotate, and the gear 83 then drives the double-sided rack 84 to move, and the double-sided rack 84 then drives the cartoon man 85 to pop out forward. At the same time, the double-sided rack 84 pushes the window 88 open through the connecting rod 89, which effectively increases the interest of the exhibits.

An arc-shaped limiting track 102 is provided at the lower end of the circular groove 9. The end of the auxiliary pendulum rod 101 is rotatably connected to a roller 103, and the roller 103 is adapted to the arc-shaped limiting track 102. During the movement of the pendulum rod 4, the auxiliary pendulum rod 101 keeps synchronous swinging with the pendulum rod 4. Therefore, the pendulum rod 4 can be limited by limiting the auxiliary pendulum rod 101 through the arc-shaped limiting track 102, and the roller 103 rolling in the arc-shaped limiting track 102 can reduce friction resistance.

[0032] Reference Figure 3 A single-chip microcomputer is arranged inside the pendulum clock body 1, and the output end of the digital tube 7 is electrically connected to the input end of the single-chip microcomputer, and the output end of the single-chip microcomputer is electrically connected to the input end of the driving motor.

[0033] Reference Figure 1 The inner wall of the concave clock dial 2 is provided with fan-shaped time modification scales 11 along the circumferential direction. The time modification scales 11 are made of UV printing material. The time modification scales 11 facilitate and intuitively see the position of the pendulum 5, can increase the brightness and artistic effect of the product, protect the surface of the product, and have high hardness, corrosion resistance, and friction resistance, and are not prone to scratches.

[0034] Working principle: First, the pressing block 63 is squeezed downward, and the pressing block 63 moves downward and drives the return spring 64 to be compressed. Then the wedge-shaped rubber block 62 loses the squeezing of the pressing block 63 and no longer maintains close contact with the outer wall of the pendulum 4. At this time, the pendulum 5 can be dragged to move along the length direction of the pendulum 4, thereby completing the pendulum length adjustment. After releasing, the pressing block 63 squeezes the wedge-shaped rubber block 62 under the action of the return spring 64. The wedge-shaped rubber block 62 abuts against the outer wall of the pendulum 4 at this time, thereby fixing the pendulum 5. The pendulum that can move up and down can guide the audience to actively adjust the position of the pendulum 5 and observe the time it takes for the pendulum 5 to swing back and forth once. The time will be synchronously displayed on the digital tube 7, which is convenient for the audience to watch and understand intuitively.

[0035] In order to increase the interest of the exhibits, a cartoon figure pop-up mechanism 8 is provided. When the pendulum swings back and forth for exactly one second, the driving motor is responsible for driving the gear 83 to rotate, and the gear 83 then drives the double-sided rack 84 to move, and the double-sided rack 84 then drives the cartoon figure 85 to pop out forward. At the same time, the double-sided rack 84 pushes the window 88 open through the connecting rod 89, which effectively increases the interest of the exhibits. The slider 86 cooperates with the slide groove 87 to ensure that the cartoon figure 85 moves smoothly, and the cartoon figure 85 with a thumbs up pops out;

[0036] At the same time, the pendulum limiting mechanism 10 can effectively limit the swinging area of ​​the pendulum 5. During the movement of the pendulum 4, the auxiliary pendulum 101 keeps swinging synchronously with the pendulum 4. Therefore, the pendulum 4 can be limited by limiting the auxiliary pendulum 101 through the arc-shaped limiting track 102, and the roller 103 rolling in the arc-shaped limiting track 102 can reduce the friction resistance.

[0037] This application adopts the form of model interaction combined with mechanical demonstration for display, which greatly improves the display effect.
