Description

Technical Field

[0001] The present invention relates to the technical field of popular science exhibits, and in particular to a timing method based on a time display device. Background Art

[0002] Popular science exhibits are both scientific and vivid, presenting scientific knowledge in a vivid and visual way. They are often displayed in science and technology museums, science and education centers, and other places. Through permanent and short-term exhibitions, engaging, experiential, and interactive exhibits, and supplementary display methods, they aim to stimulate scientific interest and enlighten scientific concepts, thereby providing public education.

[0003] Furthermore, most existing timekeeping demonstration devices simply enlarge existing clock-type timers for display. For example, Chinese Patent Publication No. CN211928899U, titled "A Clock Science Popularization Demonstration Device," utilizes a simulated mechanical clock, showcasing its internal mechanisms through transparent acrylic. However, because these timekeeping mechanisms are relatively common in existing technology, public interest in exploring them is relatively low, and their effectiveness in stimulating public interest in science and providing scientific enlightenment is limited.

DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] For ease of understanding, the specific structure and working mode of the present invention are further described below with reference to the accompanying drawings:

[0037] The specific structure of the present invention refers to Figure 1-9 As shown, its main structure includes an inclined timing track 40 and a ball feeding mechanism 10 that continuously feeds a timing ball toward the timing track 40 with equal time difference. The timing track 40 is set to at least two arranged in sequence from top to bottom, and the number of timing balls stored in the timing track 40 represents the number of time units of the current timing track 40. A ball guide assembly 60 for distributing timing balls is provided between the goal end of the timing track 40 and the track end of the ball feeding track 30. The top or bottom timing track 40 is used as the priority track for the ball guide assembly 60 to preferentially distribute timing balls. The vertical direction from the priority track to its adjacent timing track 40 is the advancement direction. When the number of timing balls on the priority track reaches the set number, the timing ball is distributed to the first timing track 40 along the advancement direction whose number of timing balls has not reached the set number. Thereafter, all the timing balls are released from the timing track 40 whose number of timing balls reaches the set number. The time display is achieved by loading and releasing the timing balls on the timing track 40. Compared with the traditional pointer timing mechanism, it is more novel and more effective in stimulating the public's interest in science, and ultimately achieves a better effect of enlightening science. The timing method of the time display device includes the following steps:

[0038] S1. The ball feeding mechanism continuously feeds a timing ball toward the bottom timing track 40 at equal time differences, and each time a timing ball is fed represents an increase of one time unit for the timing track 40;

[0039] S2. When the number of timing balls on the bottom timing track 40 reaches the set number, the ball guide assembly 60 distributes the timing balls to the first timing track 40 above it whose number of timing balls does not reach the set number. After that, all timing balls are released from the timing track 40 that has reached the set number of timing balls.

[0040] S3. Repeat steps S1-S2 until the top timing track 40 reaches the set number. At this time, the timing balls on all timing tracks 40 are released, completing a timing cycle.

[0041] For example, the timing tracks 40 can be set to two, distributed upper and lower. The time unit indicated by the upper timing track 40 is hours, and the set number of timing balls stored is 12 or 24. The time unit indicated by the lower timing track 40 is minutes, and the set number of timing balls stored is 59. In this embodiment, the time difference between the ball feeding mechanism 10 and the timing ball feeding track 30 is 30 seconds, but because one of the timing balls fed to the ball feeding track 30 twice will be centrifugally derailed, the time interval between the timing balls fed into the ball guide assembly 60 is one minute. Initially, timing balls are set on both timing tracks 40, and the ball guide assembly 60 preferentially distributes the timing balls to the lower timing track 40. When the number of timing balls on the lower timing track 40 reaches 59, the time is 0 hours and 59 minutes. The subsequent timing balls are distributed to the upper timing track 40, and all timing balls are released from the lower timing track 40. At this time, the time is 1 hour and 0 minute, thereby realizing time timing. Of course, in this embodiment, the time unit represented by the lower timing track 40 can also be set to ten minutes, and the set number of timing balls stored is 5. In addition, the timing track 40 receives a timing ball every ten minutes; initially, timing balls are set on both timing tracks 40, and the ball guide assembly 60 preferentially allocates the timing balls to the lower timing track 40. When the number of timing balls on the lower timing track 40 reaches 5, the time is 0 hours and 50 minutes. The subsequent timing balls are allocated to the upper timing track 40, and all timing balls are released from the lower timing track 40. At this time, the time is 1 hour and 0 minute.

[0042] Of course, in actual implementation, the timing track 40 may be provided with various other numbers, so that timing can be achieved based on the number of balls on the timing track 40. Below, for the embodiment in which the timing track 40 is provided with three, the ball guide assembly 60 for distributing the timing balls and the ball blocking and releasing assembly 50 for blocking and releasing the timing balls on the timing track 40 are further described.

[0043] In this embodiment, Figure 2 As shown, the timing track 40 is configured to include, from top to bottom, an hour track 41, a tens minute track 42, and a units minute track 43. The hour track 41 represents the time unit in hours and is configured to store 12 timing balls. The tens minute track 42 represents the time unit in ten minutes and is configured to store 5 timing balls. The units minute track 43 represents the time unit in minutes and is configured to store 9 timing balls. In this embodiment, the time interval between consecutive timing balls received by the ball guide assembly 60 is one minute.

[0044] like Figure 2-4As shown, the ball guide assembly 60 is connected to the ball supply mechanism 10 via the tilted ball delivery track 30. The ball guide assembly 60 receives the timing ball at the end of the ball delivery track 30. The ball guide assembly 60 includes a first ball guide groove 61 and a second ball guide groove 62, which are arranged sequentially along the timing ball delivery direction and can swing about a horizontal axis perpendicular to the length of the timing track 40. The first and second ball guide grooves 61, 62 form a ball guide bridge connecting the hour track 41 and the ball delivery track 30. That is, when the ball guide bridge is connected, the timing ball delivered from the ball delivery track 30 is distributed to the hour track 41. In addition, the first ball guide groove 61 and the second ball guide groove 62 both have a broken bridge state and a bridge state to form a ball guide bridge, and when the first ball guide groove 61 in the ball guide bridge is in the broken bridge state, the ball delivery track 30 is connected to the minute units digit track 43, and the timing ball delivered by the ball delivery track 30 will be distributed to the minute units digit track 43; when the first ball guide groove 61 and the second ball guide groove 62 are in the bridge state and the broken bridge state respectively, the ball delivery track 30 is connected to the minute tens digit track 42, and the timing ball delivered by the ball delivery track 30 will be distributed to the minute tens digit track 42.

[0045] Specifically, the structure for executing the rotation drive of the first ball guide groove 61 and the second ball guide groove 62 in the ball guide assembly 60 is as follows: Figure 4 and Figure 5 The ball guide assembly 60 further includes a ball guide power mechanism for driving the first ball guide groove 61 and the second ball guide groove 62 to swing. The ball guide power mechanism includes a first drive wheel 613 and a second drive wheel 623 driven by a gear transmission group 63 and performing synchronous rotational motion around the same horizontal axis. A first drive rod 611 and a second drive rod 621 are respectively disposed above the outer edges of the first drive wheel 613 and the second drive wheel 623, which can be raised and lowered and slid in the vertical direction. Six inner grooves 6131 are evenly distributed along the outer edge of the first drive wheel 613. Under normal circumstances, the outer edge of the first driving wheel 613 abuts the first driving rod 611 and keeps rising, so that the first ball guide groove 61 is in a broken bridge state, and when any inner groove 6131 rotates to be directly below the first driving rod 611, the first driving rod 611 descends, so that the first ball guide groove 61 is in a bridging state; the outer edge of the second driving wheel 623 is provided with a top block 6231 corresponding to five of the inner grooves 6131. ​​Under normal circumstances, the outer edge of the second driving wheel 623 abuts the second driving rod 621 and keeps descending, so that the second ball guide groove 62 rotates to the bridging state, and when any top block 6231 rotates to be directly below the second driving rod 621, it pushes the second driving rod 621 to rise, so that the second ball guide groove 62 rotates to the broken bridge state; the first driving wheel 613 and the second driving wheel 623 are driven by the gear transmission group 63 connected to the servo motor 90, and the time it takes to drive the first driving wheel 613 and the second driving wheel 623 to rotate one circle is 1 hour.

[0046] When the current time represented by the timing track 40 is 0 hours and 0 minutes, the state of the ball guide power mechanism is the initial state. According to the explanation of the above-mentioned ball timing distribution rules, in this initial state, the first ball guide groove 61 and the second ball guide groove 62 both have a broken bridge state and a bridge state to form a ball guide bridge, that is, the timing ball is allocated to the hour track 41. At this time, the number of timing balls on all timing tracks 40 has reached the set number, and all timing tracks 40 have released all timing balls. Therefore, in this state, one of the inner grooves 6131 on the first driving wheel 613 that does not correspond to the top block 6231 is located directly below the first driving rod 611. At this time, the first driving rod 611 descends, and the first ball guide groove 61 is in the bridge state. The outer edge of the second driving wheel 623 abuts the second driving rod 621 to keep descending, so that the second ball guide groove 62 rotates to the bridge state.

[0047] Afterward, the first drive wheel 613 and the second drive wheel 623 begin to rotate at a constant speed. During this rotation, the inner groove 6131 separates from the first drive rod 611, and the outer edge of the first drive wheel 613 abuts the first drive rod 611, causing the first drive rod 611 to remain elevated, thus breaking the first ball guide groove 61. In this state, the ball delivery track 30 is connected to the minute digit track 43, and the timing ball delivered by the ball delivery track 30 is distributed to the minute digit track 43.

[0048] Since the time it takes for the first driving wheel 613 and the second driving wheel 623 to rotate at a constant speed for one circle is 1 hour, and the number of the inner grooves 6131 is six evenly distributed circumferentially around the outer edge of the first driving wheel 613, the time interval for adjacent inner grooves 6131 to rotate to the position directly below the first driving rod 611 is 10 minutes. Therefore, at the time node of 0:10, the inner groove 6131 adjacent to the inner groove 6131 in the initial state rotates to directly below the first drive rod 611, and the first ball guide groove 61 is in the bridging state again; and the top block 6231 corresponding to the inner groove 6131 rotates to directly below the second drive rod 621, pushing the second drive rod 621 to rise, so that the second ball guide groove 62 rotates to the broken bridge state; in this state, when the first ball guide groove 61 and the second ball guide groove 62 are in the bridging state and the broken bridge state respectively, the ball delivery track 30 is connected to the minute tens digit track 42, and the timing ball delivered by the ball delivery track 30 will be distributed to the minute tens digit track 42, that is, a timing ball is added to the minute tens digit track 42. Similarly, as the first driving wheel 613 and the second driving wheel 623 continue to move and rotate, the ball feeding track 30 is connected to the minute digit track 43, and when the next adjacent inner groove 6131 rotates to just below the first driving rod 611, the ball feeding track 30 is connected to the minute tens digit track 42 again, and finally when the first driving wheel 613 and the second driving wheel 623 rotate to the initial state again, the ball feeding track 30 is connected to the hour track 41 to add a timing ball on the hour track 41, that is, the current time is 1 hour and 0 minutes.

[0049] For other embodiments where the number of timing tracks 40 is not three, such as when there are two timing tracks 40, only the first ball guide groove 61 and the first drive wheel 613 are required. The inner groove 6131 corresponds to the time units represented by the two timing tracks 40 and the time it takes for the first drive wheel 613 to rotate once. For example, if the upper timing track 40 represents the time unit of hours, the lower timing track 40 represents the time unit of ten minutes, and the time it takes for the first drive wheel 613 to rotate once is one hour, then one inner groove 6131 is sufficient. The same logic applies to other embodiments where the number of timing tracks 40 is greater than the number of minutes, and they will not be detailed here.

[0050] Of course, the rotation of the first ball guide groove 61 and the second ball guide groove 62 can also be executed by the controller controlling the motor or electric cylinder and other electric actuators at a preset time, but since it is impossible to demonstrate the clever arrangement of the mechanical mechanism, it can be implemented as an alternative implementation method.

[0051] In addition, the connection structures of the first driving rod 611 and the second driving rod 621 and the first ball guide groove 61 and the second ball guide groove 62 are as follows: Figure 4The first driving rod 611 and the second driving rod 621 are sleeved with a guide sleeve 64 fixed to the timing track 40 to enable the first driving rod 611 and the second driving rod 621 to slide stably along the vertical axis. In addition, the tops of the first driving rod 611 and the second driving rod 621 are horizontally bent, and the bending sections of the first driving rod 611 and the second driving rod 621 are respectively provided with the first driving long hole 6111 and the second driving long hole 6211, whose hole lengths are distributed horizontally. The axes of the first driving long hole 6111 and the second driving long hole 6211 are parallel to the swing axes of the first guide ball groove 61 and the second guide ball groove 62. The first transmission column 612 and the second transmission column 622, which are respectively axially inserted into the first driving long hole 6111 and the second driving long hole 6211, are respectively fixed on the first guide ball groove 61 and the second guide ball groove 62. The first transmission column 612 and the second transmission column 622 are respectively pushed to move by the hole walls of the first driving long hole 6111 and the second driving long hole 6211, so as to respectively drive the first guide ball groove 61 and the second ball guide groove 62 to rotate. Of course, in actual implementation, while retaining the guide sleeve 64, the first and second drive rods 611, 621 can also utilize floating joints, as used in conventional timing systems, to connect to the first and second ball guide grooves 61, 62, respectively. Taking the first drive rod 611 as an example, the ends of the floating joints are hinged to the top of the first drive rod 611 and the sidewall of the first ball guide groove 61, respectively, with the hinge axis parallel to the rotation axis of the first ball guide groove 61.

[0052] Ball blocking and ball releasing assembly 50 as shown Figure 2 and Figure 6 As shown, the ball blocking and releasing assembly 50 includes a ball blocking and releasing rod 51 that slides perpendicular to the timing track 40. The ball blocking and releasing rod 51 constrains the timing ball within the timing track 40. The ball blocking and releasing rod 51 is driven by a ball releasing power group and moves away from the timing track 40 within a set time to release all timing balls in the timing track 40.

[0053] Specifically, the ball-blocking and releasing assembly 50 includes a fixed seat 53 and a swinging rod 54 that swings about a first horizontal axis on the fixed seat 53. The swinging path of the swinging rod 54 is parallel to the cross-section of the timing track 40. The swinging rod 54 is L-shaped, with its vertical section connected to the ball-blocking and releasing rod 51. A cam 56, which is rotatably engaged with the swinging rod 54 and is parallel to the first horizontal axis, is rotatably engaged with the swinging rod 54 on the fixed seat 53. The flange of the cam 56 abuts the horizontal section of the swinging rod 54, causing the swinging rod 54 to swing and drive the ball-blocking and releasing rod 51 to slide away from the timing track 40, thereby releasing all the timing balls on the timing track 40. Furthermore, an elastic member 58 is connected between the horizontal section of the swing arm 54 and the fixed seat 53. When the flange portion separates from the horizontal end of the swing arm 54, i.e., when the timing ball on the timing track 40 is released, the elastic member 58 drives the swing arm 54 to swing back, causing the ball-blocking and releasing rod 51 to return to the timing track 40 and continue to block the timing ball on the timing track 40. The ball-releasing power unit also includes a gear assembly 57 for driving the cam 56 to rotate.

[0054] In order to better implement the rotation of the above-mentioned rocker arm 54, a protrusion 55 is provided at the bottom of the horizontal section of the rocker arm 54. The protrusion 55 is set as a roller parallel to the axis of the first horizontal axis. The roller rotates around its own axis and is engaged with the bottom of the horizontal section of the rocker arm 54. The rolling friction between the roller and the outer wall of the cam 56 reduces the friction between the rocker arm 54 and the cam 56.

[0055] Furthermore, to further ensure the ball-blocking effect of the swing arm 54, a guide sleeve 52 is fixed to the timing track 40, serving as a horizontal guide for the ball-blocking and ball-releasing rod 51. The connection between the ball-blocking and ball-releasing rod 51 and the swing arm 54 is as follows: a transmission slot 541 is provided at the top of the vertical section of the swing arm 54, with the axis of the transmission slot 541 parallel to the first horizontal axis. A transmission slide 511 is fixed to the ball-blocking and ball-releasing rod 51, axially inserted into the transmission slot 541. As the swing arm 54 swings, the wall of the transmission slot 541 within the swing arm 54 pushes the transmission slide 511, thereby forcing the ball-blocking and ball-releasing rod 51 to slide back and forth perpendicularly to the timing track 40.

[0056] In an embodiment where the timing track 40 is configured as an hour track 41, a minute tens track 42, and a minute units track 43, three sets of ball-blocking and ball-releasing levers 51 are provided for use with the hour track 41, the minute tens track 42, and the minute units track 43, respectively. Furthermore, three sets of ball-releasing power groups are provided for use with the three sets of ball-blocking and ball-releasing levers 51, respectively. The gear sets 57 of the three ball-releasing power groups are all driven by a servo motor 90, and the transmission ratios between the three gear sets 57 corresponding to the hour track 41, the minute tens track 42, and the minute units track 43, respectively, are 72:6:1. The time it takes for the minute tens track 42 to rotate once is one hour. Consequently, the time intervals for releasing the timing ball by the ball-blocking and ball-releasing levers 51 at the hour track 41, the minute tens track 42, and the minute units track 43, respectively, are 12 hours, 1 hour, and 10 minutes.

[0057] Of course, the movement of the ball blocking and releasing rod 51 can also be executed by a controller controlling an electric actuator such as a motor or an electric cylinder at a preset time, but since it is impossible to demonstrate the clever arrangement of the mechanical mechanism, it is implemented as an alternative embodiment.

[0058] It is worth mentioning that the time display device can also be used in conjunction with the following mechanical energy conversion demonstration device.

[0059] Mechanical energy demonstration device such as Figure 9 As shown, the main structure of the mechanical energy demonstration device is the ball delivery track 30 in the time display device and the ball distribution mechanism 70 that alternately delivers the timing ball supplied by the ball delivery mechanism 10 to the upper part of the ball delivery track 30 with the first gravity potential energy and the second gravity potential energy. Figure 1 In the illustrated gyration structure, the first gravitational potential energy is less than the second gravitational potential energy. Therefore, the kinetic energy converted from the timing ball, which is fed into the upper portion of the ball-feeding track 30 by the first gravitational potential energy and slides onto the ball-feeding track 30, is less than the kinetic energy converted from the timing ball, which is fed into the upper portion of the ball-feeding track 30 by the second gravitational potential energy and slides onto the ball-feeding track 30. Specifically, when the timing ball, fed into the upper portion of the ball-feeding track 30 by the first gravitational potential energy, slides along the ball-feeding track 30 to the end of the ball-feeding track 30, the kinetic energy converted is small and the timing ball cannot escape the track. Therefore, the timing ball directly follows the gyration trajectory at the end of the ball-feeding track 30 and is ejected from the end of the track. However, when the timing ball, fed into the upper portion of the ball-feeding track 30 by the second gravitational potential energy, slides along the ball-feeding track 30 to the end of the ball-feeding track 30, the kinetic energy is greater and the timing ball will centrifugally derail at the gyration structure of the ball-feeding track 30, thereby achieving a visual demonstration of the conversion between different gravitational potential energies and kinetic energies.

[0060] Specifically, the first gravitational potential energy and the second gravitational potential energy are alternately fed into the ball distribution mechanism 70 on the upper portion of the ball feeding track 30. Figure 9As shown, the ball distribution mechanism 70 includes a housing 71 fixed to the ball delivery track 30, an upper track 73 fixed to the housing 71 and connected to the ball supply end of the ball delivery mechanism 10, and a lower track 76 fixed to the housing 71 and arranged below the upper track 73. A binary ball distribution rotating block 74 is disposed within the housing 71 between the upper track 73 and the lower track 76. The binary ball distribution rotating block 74 is rotatable about a horizontal axis perpendicular to the ball delivery track 30. A primary ball distribution groove 741 and a secondary ball distribution groove 742 are respectively formed on either side of the top of the binary ball distribution rotating block 74. When the binary ball distribution rotating block 74 rotates to its extreme positions, the primary ball distribution groove 741 and the secondary ball distribution groove 742 respectively dock with the ball outlet end of the upper track 73. In the initial state, taking the limited docking of the first-level ball distribution groove 741 with the upper track 73 as an example, when the first-level ball distribution groove 741 receives the timing ball, it will push the binary ball distribution rotating block 74 to rotate toward the side of the first-level ball distribution groove 741. At this time, the second-level ball distribution groove 742 is docked with the ball outlet end of the upper track 73, and the timing ball is transported from the ball guide track 72 to the ball delivery track 30 along the ball delivery direction of the upper track 73. That is, it can be regarded as the timing ball being directly sent into the ball delivery track 30 under the gravitational potential energy on the upper track 73. After that, since the secondary ball-dividing groove 742 is connected to the ball-out end of the upper track 73 at this time, the next timing ball sent by the ball-delivering mechanism 10 will be delivered to the secondary ball-dividing groove 742. Similarly, when the secondary ball-dividing groove 742 receives the timing ball, it will push the binary ball-dividing rotating block 74 to rotate toward the secondary ball-dividing groove 742, and then make the primary ball-dividing groove 741 connect to the ball-out end of the upper track 73; and the timing ball will collide with the baffle 75 in the opposite direction of the ball-delivering direction of the upper track 73, converting the kinetic energy of the timing ball after movement into elastic potential energy in the collision process. After that, the timing ball moves. It can be reduced and transported to the lower track 76, and finally transported to the ball delivery track 30 by the lower track 76. Since the lower track 76 is lower than the upper track 73, the gravitational potential energy sent from the lower track 76 to the ball delivery track 30 is relatively small; in addition, since the kinetic energy converted from the gravitational potential energy is mostly converted into elastic potential energy during the collision during the transportation from the upper track 73 to the lower track 76, that is, there is a large kinetic energy consumption. Therefore, the power of the timing ball transported from the lower track 76 to the tail end of the ball delivery track 30 is less than the kinetic energy of the timing ball transported from the upper track 73 to the tail end of the ball delivery track 30.In this embodiment, the rotation of the binary ball-dividing rotating block 74 after receiving the ball is cleverly utilized, so that the secondary ball-dividing groove 742 and the primary ball-dividing groove 741 of the binary ball-dividing rotating block 74 are respectively switched to docking with the ball-delivering track 30, thereby transporting the timing ball with different gravitational potential energies to the upper part of the ball-delivering track 30, and utilizing the difference in kinetic energy finally converted by the timing ball transported to the tail end of the ball-delivering track 30, two sets of demonstration states of the timing ball moving along the trajectory of the ball-delivering track 30 and moving away from the ball-delivering track 30 are realized; the mechanical mechanism of the demonstration device is cleverly arranged, the structure is stable and can realize alternating demonstration continuously, which can effectively stimulate the public's interest in science and ultimately achieve a better effect of enlightening science.

[0061] On the basis of the above, in order to further realize the recycling of the timing ball and improve the automation level of the time display device. Figure 1 As shown, the time display device further includes a ball receiving track 20 , which has a scoring end for receiving the timing ball released by the timing track 40 , and a ball discharging end for supplying the timing ball to the ball feeding mechanism 10 .

[0062] In addition, in order to automatically recycle the timing ball that deviates from the ball delivery track 30 in the mechanical energy conversion demonstration device, as shown in FIG. Figure 1 As shown, a ball collection hopper 80 connected to the ball receiving track 20 is fixed inside the rotating structure of the ball delivery track 30. A barrier 31 is provided at the outer edge of the rotating structure of the ball delivery track 30 to collide the timing ball that derails the rotating structure into the ball collection hopper 80. The provision of this barrier 31, combined with the mechanical energy conversion demonstration device, can also realize the collision ring between the timing ball and the barrier 31, and demonstrate the conversion between kinetic energy and elastic potential energy, more effectively stimulating the public's interest in science and ultimately achieving a better scientific enlightenment effect.

[0063] On the basis of the above, the ball delivery mechanism 10 is as follows Figure 1 、 Figure 7 and Figure 8As shown, the ball delivery mechanism 10 includes a vertically arranged ball delivery cylinder 13. The lower sidewall of the ball delivery cylinder 13 is provided with a ball inlet 132 connected to the ball outlet end of the ball receiving track 20. The upper sidewall of the ball delivery cylinder 13 is provided with a ball outlet 131, which is connected to the ball guide assembly 60 via the ball delivery track 30. The inner coaxial rotation of the ball delivery cylinder 13 is equipped with a screw conveyor rod 14 for conveying the timing ball to the ball outlet 131. The screw conveyor rod 14 is driven by a gear power unit connected to the servo motor 90, and the time for the screw conveyor rod 14 to rotate once is 30 seconds. Of course, in actual implementation, the time display device can also be used alone without combining with the mechanical energy conversion demonstration device. If the time display device is used alone, the time for the screw conveyor rod 14 to rotate once is the same as the time unit of the priority track in the timing track 40. For example, in the above embodiment, the time unit of the priority track is minutes, and the time for the screw conveyor rod 14 to rotate once is 1 minute.

[0064] It is worth mentioning that in this application, the servo motor 90 that controls the rotation of the screw conveying rod 14, the first driving wheel 613, the second driving wheel 623 and the cam 56 is the same. Figure 3 As shown, a driving gear 91 is coaxially fixed to the output shaft of the servo motor 90, and the driving gear 91 is engaged with one of the gear sets 57. In addition, a gear linkage mechanism is provided between the gear set 57 that drives the cam 56 to rotate and the gear transmission set 63 that drives the first driving wheel 613 and the second driving wheel 623. The gear linkage mechanism can be used to control the transmission ratio of the gear set 57 and the gear transmission set 63 to a desired ratio. In addition, as Figure 7 As shown, a screw gear 141 is coaxially fixed to the lower end of the screw conveying rod 14, and a shaft 111 is radially passed through the side wall of the ball feeding cylinder 13, as shown in FIG. Figure 3 As shown, one end of the shaft 111 is coaxially fixed with a ball-feeding bevel gear 12 that meshes with the screw gear 141, and the other end is coaxially fixed with a ball-feeding gear 11 that meshes with the driving gear 91. The ball-feeding bevel gear 12 and the ball-feeding gear 11 at both ends of the shaft 111 control the transmission ratio between the screw gear 141 and the driving gear 91 to a desired ratio. This is driven by a servo motor 90, which effectively ensures the precise coordination between the various transmission structures and guarantees the accuracy of the time display device.
