Description

Technical Field

[0001] This invention relates to the field of science popularization exhibits, specifically a mechanical energy conversion demonstration device and a time display device. Background Technology

[0002] Science exhibits are scientifically accurate and engaging, presenting scientific knowledge in a vivid and illustrative way. They are often displayed in science museums and educational centers, and through permanent and temporary exhibitions, using participatory, experiential, and interactive exhibits and supplementary display methods, the aim is to stimulate scientific interest and inspire scientific concepts, thereby providing science education to the public.

[0003] Most existing devices used to demonstrate mechanical energy, such as the one described in the text of Chinese Patent Publication No. CN211979975U entitled "A Demonstration Device for Converting Mechanical Energy into Kinetic Energy," feature an adjustable-angle main body that serves as the sliding track for a pulley cart, thus demonstrating the conversion between different gravitational potential energies and kinetic energies. The demonstration process of this type of device is relatively conventional, resulting in relatively low public interest and limited effectiveness in stimulating public scientific interest and inspiring scientific understanding.

[0004] Furthermore, most existing timekeeping demonstration devices merely enlarge and display existing clock-like timepieces. For example, the text of Chinese Patent Publication No. CN211928899U, titled "A Clock and Watch Science Popularization Demonstration Device," describes a simulated mechanical clock using transparent acrylic to showcase its internal mechanical mechanism. Because this type of timekeeping structure is relatively conventional in existing technology, the public's desire to explore it is relatively low, and its effect on stimulating public scientific interest and inspiring scientific understanding is generally limited. Summary of the Invention

[0005] To avoid and overcome the technical problems existing in the prior art, the present invention provides a mechanical energy conversion demonstration device and a time display device. Based on reasonable structure and accurate and reliable operation, the arrangement of mechanical mechanism is improved, and the ingenious design can be combined with a timing device to further stimulate public scientific interest and ultimately achieve a better effect of enlightening science.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A mechanical energy conversion demonstration device includes an inclined ball-feeding track, a ball-feeding mechanism that continuously supplies timing balls at equal time intervals, and a ball-distributing mechanism that alternately feeds the timing balls supplied by the ball-feeding mechanism into the upper part of the ball-feeding track with a first gravitational potential energy and a second gravitational potential energy. The tail of the ball-feeding track has a spiral structure. The first gravitational potential energy is less than the second gravitational potential energy. The timing balls fed by the first gravitational potential energy slide along the ball-feeding track and are discharged from the end of the track. The timing balls fed by the second gravitational potential energy derail centrifugally at the spiral structure of the ball-feeding track while sliding along the track.

[0007] As a further aspect of the present invention: the ball-distributing mechanism includes a housing fixed to the ball-feeding track, an upper-level track fixed to the housing and connected to the ball-feeding end of the ball-feeding mechanism, and a lower-level track fixed to the housing and distributed below the upper-level track. A binary ball-distributing rotating block is disposed inside the housing between the upper-level and lower-level tracks. The binary ball-distributing rotating block can rotate around a horizontal axis perpendicular to the ball-feeding track. The top two sides of the binary ball-distributing rotating block each have a primary ball-distributing groove and a secondary ball-distributing groove. When the binary ball-distributing rotating block rotates to its extreme positions on both sides, the primary ball-distributing groove and the secondary ball-distributing groove respectively connect with the upper-level track. The ball-out end of the track is connected; when the first-level ball-splitting groove receives the timing ball, it pushes the binary ball-splitting rotating block to rotate to one side of the first-level ball-splitting groove, and transports the timing ball from the guide track to the delivery track along the ball-feeding direction of the upper track. At the same time, it also connects the second-level ball-splitting groove with the ball-out end of the upper track; when the second-level ball-splitting groove receives the timing ball, it pushes the binary ball-splitting rotating block to rotate to one side of the second-level ball-splitting groove, and after the timing ball collides with the baffle to reduce its kinetic energy in the opposite direction of the ball-feeding direction of the upper track, it is transported to the delivery track by the lower track. At the same time, it also connects the first-level ball-splitting groove with the ball-out end of the upper track.

[0008] A time display device, which applies the aforementioned mechanical energy conversion demonstration device, includes a timing track with timing balls at the end of a ball-feeding track, arranged at an angle. At least two timing tracks are arranged sequentially from top to bottom, and the number of timing balls stored on each track represents the number of time units on the current timing track. A ball guide assembly for distributing timing balls is provided between the ball-feeding end of the timing track and the end of the ball-feeding track. The uppermost or lowermost timing track is designated as the priority track for the ball guide assembly to distribute timing balls. The vertical direction from the priority track to its adjacent timing track is the advancement direction. When the priority track reaches a set number of timing balls, the timing balls are distributed to the first timing track along the advancement direction where the number of timing balls has not yet reached the set number. Afterward, the timing track with the set number of timing balls releases all timing balls.

[0009] As a further embodiment of the present invention: the timing track is configured as an hour track, a tens-of-minutes track, and a units-of-minutes track arranged sequentially from top to bottom. The ball guide assembly includes a first ball guide groove and a second ball guide groove that can be arranged sequentially along the timing ball conveying direction and can swing around a horizontal axis perpendicular to the length direction of the timing track. The first ball guide groove and the second ball guide groove form a ball guide bridge connecting the hour track and the ball delivery track. Both the first ball guide groove and the second ball guide groove have a broken bridge state and a connected bridge state that form the ball guide bridge. When the first ball guide groove in the ball guide bridge is in the broken bridge state, the ball delivery track is connected to the units-of-minutes track. When the first ball guide groove and the second ball guide groove are in the connected bridge state and the broken bridge state, respectively, the ball delivery track is connected to the tens-of-minutes track.

[0010] As a further embodiment of the present invention: the ball guide assembly further includes a ball guide power mechanism for driving the first ball guide groove and the second ball guide groove to swing. The ball guide power mechanism includes a first drive wheel and a second drive wheel driven by a gear transmission set and rotating synchronously around the same horizontal axis. A first drive rod and a second drive rod that can slide up and down in the vertical direction are respectively provided above the outer edges of the first drive wheel and the second drive wheel. The outer edge of the first drive wheel has six inner grooves evenly distributed around its circumference. Under normal conditions, the outer edge of the first drive wheel abuts against the first drive rod and remains raised, so that the first ball guide groove is in a broken bridge state and rotates in any of the inner grooves. When the first drive rod is directly below the first drive rod, the first drive rod descends to make the first guide ball groove bridging. The outer edge of the second drive wheel is provided with top blocks that correspond one-to-one with the five inner grooves. Under normal conditions, the outer edge of the second drive wheel abuts against the second drive rod and remains descending so that the second guide ball groove rotates to the bridging state. When any top block rotates to directly below the second drive rod, it pushes the second drive rod to rise so that the second guide ball groove rotates to the broken bridge state. The first drive wheel and the second drive wheel are driven by a gear transmission group connected to the servo motor, and the time for the first drive wheel and the second drive wheel to rotate at a constant speed for one revolution is 1 hour.

[0011] As a further aspect of the present invention, it also includes a ball-blocking and ball-releasing assembly, which includes a ball-blocking and ball-releasing rod that slides perpendicular to the timing track. The ball-blocking and ball-releasing rod constrains the timing balls within the timing track. The ball-blocking and ball-releasing rod is driven by a ball-releasing power unit and moves away from the timing track within a set time to release all the timing balls within the timing track.

[0012] As a further embodiment of the present invention: the ball-blocking and ball-releasing assembly further includes a fixed base and a swing arm that swings around a first horizontal axis on the fixed base. The swing path of the swing arm is parallel to the cross-section of the timing track. The swing arm has an L-shaped structure, and the vertical section of the swing arm is connected to the ball-blocking and ball-releasing rod. A cam that cooperates with the swing arm is rotatably fitted on a second horizontal axis parallel to the first horizontal axis on the fixed base. The flange of the cam abuts against the horizontal section of the swing arm to cause the swing arm to swing and drive the ball-blocking and ball-releasing rod to slide off the timing track. An elastic element is connected between the horizontal section of the swing arm and the fixed base. When the flange separates from the horizontal end of the swing arm, the elastic element drives the swing arm to reset and swing, so that the ball-blocking and ball-releasing rod returns to the timing track. The ball-releasing power unit includes a gear set for driving the cam to rotate.

[0013] As a further embodiment of the present invention: the ball-blocking and ball-releasing rods are configured in three sets for use in conjunction with the hour track, the minute tens digit track, and the minute units digit track; the ball-releasing power units are configured in three sets for use in conjunction with the three sets of ball-blocking and ball-releasing rods; wherein the gear sets of the three sets of ball-releasing power units are all driven by servo motors, and the transmission ratio between the three sets of gear sets corresponding to the hour track, the minute tens digit track, and the minute units digit track is 72:6:1, and the time for the minute tens digit track to rotate one revolution is 1 hour.

[0014] As a further aspect of the present invention, it also includes a ball-receiving track, which has an inlet end for receiving the timing ball released by the timing track, and an outlet end for supplying the timing ball to the ball-feeding mechanism; a ball-collecting hopper connected to the ball-receiving track is fixed inside the swivel structure of the ball-feeding track, and a barrier is provided at the outer edge of the swivel structure of the ball-feeding track to collide timing balls that have derailed from the swivel structure into the ball-collecting hopper.

[0015] As a further embodiment of the present invention: the ball feeding mechanism includes a vertically arranged ball feeding tube, the lower part of the side wall of the ball feeding tube is provided with a ball inlet communicating with the ball outlet end of the ball receiving track, the upper part of the side wall of the ball feeding tube is provided with a ball outlet, the ball outlet is connected to the ball guide assembly through the ball feeding track, and the inside of the ball feeding tube is coaxially rotated with a spiral conveying rod for conveying the timing ball to the ball outlet, the spiral conveying rod is driven by a gear power group connected to a servo motor, and the time for the spiral conveying rod to rotate one revolution is 30 seconds.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. By designing the tail of the ball delivery track as a spiral structure, when the timing ball, fed by the first gravitational potential energy, slides along the track to the tail, its converted kinetic energy is small and it cannot detach from the track. Therefore, it will directly spiral along the tail of the track and exit from the end of the track. However, when the timing ball, fed by the second gravitational potential energy, slides along the track to the tail, its kinetic energy is large, and it will centrifugally derail at the spiral structure of the track. This provides a visual demonstration of the conversion between different gravitational potential energy and kinetic energy.

[0017] 2. By cleverly utilizing the rotation of the binary ball-splitting block after receiving the ball, the secondary and primary ball-splitting grooves of the binary ball-splitting block are switched to connect with the ball-delivery track, thereby transferring the timing ball to the upper part of the ball-delivery track by different gravitational potential energies. The difference in kinetic energy of the timing ball at the end of the track is then used to demonstrate two sets of states: the timing ball moving along the track and the timing ball moving away from the track. The demonstration device features a cleverly arranged mechanical mechanism, a stable structure, and the ability to perform alternating demonstrations continuously, effectively stimulating public scientific interest and ultimately achieving a better effect in inspiring scientific understanding.

[0018] 3. The time display is achieved by loading and releasing a timing ball on a timing track. Compared with traditional pointer timing mechanisms, this is more novel and more effective in stimulating public scientific interest, ultimately achieving a better effect in enlightening science.

[0019] 4. By using the first and second drive wheels to rotate synchronously and at a constant speed, the first and second guide ball slots in the guide ball assembly can be switched to different states, thereby distributing the timing balls to the hour track, the tens digit track of minutes, and the units digit track of minutes respectively. This mechanical layout eliminates the need to control the rotation of the first and second guide ball slots separately through system programs, further demonstrating the ingenious arrangement of the mechanical mechanism.

[0020] 5. The three gear sets that drive the three ball-stopping and ball-releasing assemblies to release or block the timing ball rotate synchronously. By setting the transmission ratio between the three gear sets, different ball-stopping and ball-releasing assemblies can be driven to release the ball at specific time points. The mechanical structure layout eliminates the need to control the movement of the ball-stopping and ball-releasing assemblies separately through system programs, further demonstrating the ingenious arrangement of the mechanical mechanism.

[0021] 6. A ball-collecting track is provided, which enables the recycling of the timing ball and ensures the overall automated operation of the device. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] For ease of understanding, the specific structure and operation of the present invention will be further described below with reference to the accompanying drawings: The specific structure of this invention is as follows: Figure 1-9 As shown, its main structure includes a mechanical energy conversion demonstration device showcasing the conversion of kinetic and potential energy, and a time display device for timing. Among them, I. Mechanical energy demonstration devices, such as Figure 9 As shown, it includes an inclined ball-feeding track 30, a ball-feeding mechanism 10 that continuously supplies timing balls with equal time intervals, and a ball-distributing mechanism 70 that alternately feeds the timing balls supplied by the ball-feeding mechanism 10 into the upper part of the ball-feeding track 30 with a first gravitational potential energy and a second gravitational potential energy. The tail of the ball-feeding track 30 is shaped like... Figure 1 The swirl structure shown has a first gravitational potential energy that is less than a second gravitational potential energy. Therefore, the kinetic energy converted when the timing ball, fed by the first gravitational potential energy, slides down the upper part of the ball delivery track 30 is less than the kinetic energy converted when the timing ball, fed by the second gravitational potential energy, slides down the ball delivery track 30. Specifically, when the timing ball fed by the first gravitational potential energy slides along the ball delivery track 30 to its tail, its converted kinetic energy is small, preventing it from detaching from the track. Therefore, it will directly follow the swirl trajectory at the tail of the ball delivery track 30 and exit from the end of the track. Conversely, when the timing ball fed by the second gravitational potential energy slides along the ball delivery track 30 to its tail, its kinetic energy is large, causing it to derail due to centrifugal force at the swirl structure of the ball delivery track 30. This provides a direct demonstration of the conversion between different gravitational potential energies and kinetic energies.

[0034] Specifically, the ball-distributing mechanism 70, located above the ball-delivery track 30, alternately receives the first and second gravitational potential energies. Figure 9As shown, the ball-distributing mechanism 70 includes a housing 71 fixed to the ball-feeding track 30, an upper track 73 fixed to the housing 71 and connected to the ball-feeding end of the ball-feeding mechanism 10, and a lower track 76 fixed to the housing 71 and distributed below the upper track 73. A binary ball-distributing rotating block 74 is disposed inside the housing 71 between the upper track 73 and the lower track 76. The binary ball-distributing rotating block 74 can rotate around a horizontal axis perpendicular to the ball-feeding track 30. The top two sides of the binary ball-distributing rotating block 74 have a primary ball-distributing groove 741 and a secondary ball-distributing groove 742, respectively. When the binary ball-distributing rotating block 74 rotates to its extreme positions on both sides, the primary ball-distributing groove 741 and the secondary ball-distributing groove 742 respectively align with the ball-out end of the upper track 73. In the initial state, taking the connection between the primary ball-splitting groove 741 and the upper track 73 as an example, when the primary ball-splitting groove 741 receives the timing ball, it will push the binary ball-splitting rotating block 74 to rotate to the side of the primary ball-splitting groove 741. At this time, the secondary ball-splitting groove 742 connects with the ball-out end of the upper track 73, and the timing ball is transported from the guide ball track 72 to the ball-delivery track 30 along the ball-delivery direction of the upper track 73. This 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. Subsequently, since the ball-ejection end of the upper track 73 is now connected to the secondary ball-splitting groove 742, the next timing ball delivered by the ball-feeding mechanism 10 will be transported to the secondary ball-splitting groove 742. Similarly, when the secondary ball-splitting groove 742 receives the timing ball, it will push the binary ball-splitting block 74 to rotate towards the secondary ball-splitting groove 742, thus causing the primary ball-splitting groove 741 to connect with the ball-ejection end of the upper track 73. The timing ball will collide with the baffle 75 against the ball-feeding direction of the upper track 73, converting the kinetic energy of the timing ball after its movement into elastic potential energy during the collision process. Afterward, the timing ball moves... The ball can be lowered and transported to the lower track 76, and finally from the lower track 76 to the ball delivery track 30. 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 most of the kinetic energy converted from gravitational potential energy is converted into elastic potential energy during the collision when the ball is transported from the upper track 73 to the lower track 76, there is a large loss of kinetic energy. Therefore, the kinetic energy of the timing ball transported from the lower track 76 to the end of the ball delivery track 30 is less than that of the timing ball transported from the upper track 73 to the end of the ball delivery track 30.In this embodiment, the rotation of the binary ball-splitting block 74 after receiving the ball is cleverly utilized, causing the secondary ball-splitting groove 742 and the primary ball-splitting groove 741 of the binary ball-splitting block 74 to switch to dock with the ball-delivery track 30, thereby transmitting the timing ball to the upper part of the ball-delivery track 30 by different gravitational potential energies. By utilizing the difference in kinetic energy of the timing ball finally converted at the end of the ball-delivery track 30, two sets of demonstration states are achieved: the timing ball moving along the trajectory of the ball-delivery track 30 and the timing ball moving away from the ball-delivery track 30. The mechanical mechanism of the demonstration device is cleverly arranged, the structure is stable, and it can realize continuous alternating demonstrations, which can effectively stimulate public scientific interest and ultimately achieve a better effect of enlightening science.

[0035] II. Time demonstration device, mainly as follows: Figure 1-6 As shown, the device includes inclined timing tracks 40, which cooperate with the end of the ball-feeding track 30 of the aforementioned mechanical energy demonstration device to receive timing balls from the end of the ball-feeding track 30. At least two timing tracks 40 are arranged sequentially from top to bottom, and the number of timing balls stored on each track 40 represents the current number of time units on that track. A ball-guiding assembly 60 for distributing timing balls is provided between the ball-feeding end of the timing track 40 and the end of the ball-feeding track 30. The uppermost or lowermost timing track 40 is the priority track for the ball-guiding assembly 60 to distribute timing balls. The vertical direction from the priority track to its adjacent timing track 40 is the advancement direction. When the priority track reaches a set number of timing balls, the timing balls are distributed to the first timing track 40 along the advancement direction where the number of timing balls has not yet reached the set number. Afterward, timing tracks 40 that have reached the set number of timing balls release all timing balls. Using the loading and releasing of timing balls on the timing tracks 40 to display time is more novel and effectively stimulates public scientific interest compared to traditional pointer timing mechanisms, ultimately achieving a better effect of enlightening science.

[0036] For example, there can be two timing tracks 40, one above the other. The upper timing track 40 represents the time unit in hours and stores 12 or 24 timing balls. The lower timing track 40 represents the time unit in minutes and stores 59 timing balls. In this embodiment, the timing ball supply mechanism 10 supplies timing balls to the timing track 30 at a time difference of 30 seconds. However, since one of the timing balls delivered to the timing track 30 twice may derail due to centrifugal force, 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. 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. After that, the timing balls are distributed to the upper timing track 40, and the lower timing track 40 releases all the timing balls. The time is then 1 hour and 0 minutes, thus realizing the 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 can be 5. In addition, the timing track 40 receives one timing ball every ten minutes. Initially, timing balls are set on both timing tracks 40. The ball guide assembly 60 prioritizes the allocation of 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. After that, the timing balls are allocated to the upper timing track 40, and the lower timing track 40 releases all the timing balls. At this time, the time is 1 hour and 0 minutes.

[0037] Of course, in actual implementation, the timing track 40 can be set to various other numbers, as long as the timing can be achieved according to the number of balls on the timing track 40. Below, in an embodiment where the timing track 40 is set to 3, the structure of 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 will be further described.

[0038] In this embodiment, such as Figure 2 As shown, the timing track 40 is configured from top to bottom as an hour track 41, a tens digit minute track 42, and a units digit minute track 43. The hour track 41 represents the time unit of hours and stores 12 timing balls; the tens digit minute track 42 represents the time unit of minutes and stores 5 timing balls; the units digit minute track 43 represents the time unit of minutes and stores 9 timing balls. In this embodiment, the time interval for the ball guide assembly 60 to continuously receive timing balls is one minute.

[0039] like Figure 2-4As shown, the ball guide assembly 60 includes a first ball guide groove 61 and a second ball guide groove 62 that can be arranged sequentially along the timing ball delivery direction and can swing around a horizontal axis perpendicular to the length direction of the timing track 40. The first ball guide groove 61 and the second ball guide groove 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 in the connected state, the timing balls delivered by the ball delivery track 30 will be distributed onto the hour track 41. Furthermore, both the first ball guide groove 61 and the second ball guide groove 62 have a broken bridge state and a connected bridge state that form a ball guide bridge. 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 unit digit track 43, and the timing ball delivered by the ball delivery track 30 will be distributed to the minute unit digit track 43. When the first ball guide groove 61 and the second ball guide groove 62 are in the connected 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.

[0040] Specifically, the structure for driving the rotation 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 As shown. The ball guide assembly 60 also 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 rotating synchronously around the same horizontal axis. A first drive rod 611 and a second drive rod 621 that can slide up and down in the vertical direction are respectively provided above the outer edge of the first drive wheel 613 and the second drive wheel 623. Six inner grooves 6131 are evenly distributed around the outer edge of the first drive wheel 613. Under normal conditions, the outer edge of the first drive wheel 613 abuts against the first drive rod 611 and remains raised, so that the first guide ball groove 61 is in a broken bridge state. When any inner groove 6131 rotates to be directly below the first drive rod 611, the first drive rod 611 descends, so that the first guide ball groove 61 is in a bridged state. The outer edge of the second drive wheel 623 is provided with top blocks 6231 corresponding to five of the inner grooves 6131. ​​Under normal conditions, the outer edge of the second drive wheel 623 abuts against the second drive rod 621 and remains lower, so that the second guide ball groove 62 rotates to a bridged state. When any top block 6231 rotates to be directly below the second drive rod 621, it pushes the second drive rod 621 to rise, so that the second guide ball groove 62 rotates to a broken bridge state. The first drive wheel 613 and the second drive wheel 623 are driven by a gear transmission group 63 that is connected to the servo motor 90, and the time for the first drive wheel 613 and the second drive wheel 623 to rotate one revolution is 1 hour.

[0041] When the current time, represented by timing track 40, is 0:00, the ball guide mechanism is in its initial state. Based on the explanation of the ball timing allocation rules, in this initial state, both the first ball guide groove 61 and the second ball guide groove 62 are in a broken-bridge state and a bridged state, forming a ball guide bridge. That is, the timing balls are allocated to the hour track 41. At this time, the number of timing balls on all timing tracks 40 reaches the set number, and all timing tracks 40 release all timing balls. Therefore, in this state, one of the inner grooves 6131 on the first drive wheel 613 that does not correspond to the top block 6231 is located directly below the first drive rod 611. At this time, the first drive rod 611 descends, and the first ball guide groove 61 is in a bridged state. The outer edge of the second drive wheel 623 abuts against the second drive rod 621 and remains descending, causing the second ball guide groove 62 to rotate into the bridged state.

[0042] Subsequently, 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 against the first drive rod 611, causing the first drive rod 611 to continue rising, so that the first ball guide groove 61 is in a broken bridge state. In this state, the ball delivery track 30 is connected to the minute unit digit track 43, and the timing balls delivered by the ball delivery track 30 are distributed onto the minute unit digit track 43.

[0043] Since the time it takes for the first drive wheel 613 and the second drive wheel 623 to rotate one revolution at a constant speed is 1 hour, and the number of inner grooves 6131 is six evenly distributed around the outer edge of the first drive wheel 613, that is, the time interval between the rotation of adjacent inner grooves 6131 to the point directly below the first drive 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 be directly below the first drive rod 611, and the first ball guide groove 61 is in the bridging state again; while the top block 6231 corresponding to the inner groove 6131 rotates to be 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, the minute tens digit track 42 adds a timing ball. Similarly, as the first drive wheel 613 and the second drive wheel 623 continue to rotate, the ball delivery track 30 is connected to the minute unit digit track 43. When the next adjacent inner groove 6131 rotates to the position directly below the first drive rod 611, the ball delivery track 30 is connected to the minute tens digit track 42. Finally, when the first drive wheel 613 and the second drive wheel 623 rotate back to their initial state, the ball delivery track 30 is connected to the hour track 41, so that a timing ball is added to the hour track 41, indicating that the current time is 1 hour and 0 minutes.

[0044] For other implementations where the number of timing tracks 40 is not three, such as when the number of timing tracks 40 is set to two, only the first guide ball groove 61 and the first drive wheel 613 need to be set. The inner groove 6131 is related to the time unit 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 minutes, and the time it takes for the first drive wheel 613 to rotate once is 1 hour, then only one inner groove 6131 needs to be set. The logic is the same for other embodiments where the number of timing tracks 40 is different, and they will not be listed and described in detail here.

[0045] Of course, the rotation of the first guide ball groove 61 and the second guide ball groove 62 can also be performed by the controller controlling the electric actuator such as the motor or electric cylinder for a preset time. However, since it is impossible to demonstrate the ingenious arrangement of the mechanical mechanism, it can be implemented as an alternative implementation method.

[0046] Furthermore, the connection structures between the first drive rod 611 and the second drive rod 621 and the first guide ball groove 61 and the second guide ball groove 62, respectively, are as follows: Figure 4As shown. Guide sleeves 64, which are fixed to the timing track 40, are fitted on the bodies of the first drive rod 611 and the second drive rod 621 to enable the first drive rod 611 and the second drive rod 621 to slide stably along the vertical axis. Furthermore, the tops of the first drive rod 611 and the second drive rod 621 are bent horizontally, and the bent sections of the first drive rod 611 and the second drive rod 6211 are respectively provided with first drive elongated holes 6111 and second drive elongated holes 6211 whose hole lengths are both horizontally distributed. The axes of the first drive elongated holes 6111 and the second drive elongated holes 6211 are parallel to the swing axes of the first guide ball groove 61 and the second guide ball groove 62. The first drive column 612 and the second drive column 622 are respectively fixed on the first guide ball groove 61 and the second guide ball groove 62, respectively axially inserted into the first drive elongated holes 6111 and the second drive elongated holes 6211. The first drive column 612 and the second drive column 622 are pushed by the hole walls of the first drive elongated holes 6111 and the second drive elongated holes 6211, respectively, so as to drive the first guide ball groove 61 and the second guide ball groove 62 to rotate. Of course, in actual implementation, while retaining the guide sleeve 64, the first drive rod 611 and the second drive rod 621 can also be connected to the first guide ball groove 61 and the second guide ball groove 62 respectively using the floating joints found in existing timing systems. Taking the first drive rod 611 as an example, the two ends of the floating joint are respectively hinged to the top of the first drive rod 611 and the side wall of the first guide ball groove 61, and the hinge axis is parallel to the rotation axis of the first guide ball groove 61.

[0047] Ball blocking and ball releasing components 50 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 balls within the timing track 40. The ball blocking and releasing rod 51 is driven by the ball releasing power unit and moves away from the timing track 40 within a set time to release all the timing balls within the timing track 40.

[0048] Specifically, the ball-stopping and ball-releasing assembly 50 also includes a fixed base 53 and a swing rod 54 that swings around a first horizontal axis on the fixed base 53. The swing path of the swing rod 54 is parallel to the cross-section of the timing track 40. The swing rod 54 has an L-shaped structure, and the vertical section of the swing rod 54 is connected to the ball-stopping and ball-releasing rod 51. A cam 56 that cooperates with the swing rod 54 is rotatably fitted on a second horizontal axis on the fixed base 53 that is parallel to the first horizontal axis. The flange of the cam 56 abuts against the horizontal section of the swing rod 54 to make the swing rod 54 swing and drive the ball-stopping and ball-releasing rod 51 to slide off the timing track 40, that is, to release all the timing balls on the timing track 40. Furthermore, an elastic element 58 connects the horizontal section of the lever 54 to the fixed base 53. When the flange separates from the horizontal end of the lever 54, i.e., after the timing ball on the timing track 40 has been released, the elastic element 58 drives the lever 54 to swing back to its original position, so that the ball-release lever 51 returns to the timing track 40 to continue blocking the timing ball on the timing track 40. The ball-release power unit also includes a gear set 57 for driving the cam 56 to rotate.

[0049] To better implement the rotation of the rocker arm 54, a protrusion 55 is provided at the bottom of the horizontal section of the rocker arm 54. The protrusion 55 is a roller parallel to the first horizontal axis. The roller rotates around its own axis and is fitted at the bottom of the horizontal section of the rocker arm 54. The roller rolls and rubs against the outer wall of the cam 56, reducing the friction between the rocker arm 54 and the cam 56.

[0050] In addition, to further ensure the ball-blocking effect of the pendulum 54, a guide sleeve 52 is fixed on the timing track 40 for horizontally guiding the ball-blocking and ball-releasing rod 51. The connection between the ball-blocking and ball-releasing rod 51 and the pendulum 54 is as follows: a transmission elongated hole 541 is provided at the top of the vertical section of the pendulum 54, and the axis of the transmission elongated hole 541 is parallel to the first horizontal axis; a transmission slide 511 is fixed on the ball-blocking and ball-releasing rod 51 and is axially inserted into the transmission elongated hole 541. During the swing of the pendulum 54, the wall of the transmission elongated hole 541 in the pendulum 54 pushes the transmission slide 511 to move, thereby driving the ball-blocking and ball-releasing rod 51 to produce a sliding reciprocating motion perpendicular to the timing track 40.

[0051] In an embodiment where the timing track 40 is configured as an hour track 41, a tens-of-minutes track 42, and a units-of-minutes track 43, the ball-release lever 51 is configured in three sets, each working in conjunction with one of the hour track 41, tens-of-minutes track 42, and units-of-minutes track 43. The ball-release power unit is also configured in three sets, each working in conjunction with one of the three sets of ball-release levers 51. The gear sets 57 of the three sets of ball-release power units are all driven by servo motors 90, and the transmission ratio between the three sets of gear sets 57 corresponding to the hour track 41, tens-of-minutes track 42, and units-of-minutes track 43 is 72:6:1. Since the tens-of-minutes track 42 rotates once in one hour, the time intervals at which the ball-release levers 51 at the hour track 41, tens-of-minutes track 42, and units-of-minutes track 43 release the timing ball are 12 hours, 1 hour, and 10 minutes, respectively.

[0052] Of course, the movement of the ball-blocking and ball-releasing rod 51 described above can also be executed by the controller controlling the motor or electric cylinder and other electrical actuators for a preset time, but since it is impossible to demonstrate the ingenious arrangement of the mechanical mechanism, it is implemented as an alternative implementation method.

[0053] Building upon the above, to further realize the cyclical use of the timing ball and improve the automation level of the time display device, such as... Figure 1 As shown, the time display device also includes a ball receiving track 20, which has a receiving end for receiving the timing ball released by the timing track 40, and a ball receiving end for supplying the timing ball to the ball delivery mechanism 10.

[0054] In addition, to automatically recover the timing ball that deviates 30° from the ball delivery track in the mechanical energy conversion demonstration device, such as... Figure 1 As shown, a ball-collecting hopper 80, connected to the ball-receiving track 20, is fixed inside the swivel structure of the ball-feeding track 30. A barrier 31 is provided at the outer edge of the swivel structure of the ball-feeding track 30 to collide any timing balls that derail from the swivel structure into the ball-collecting hopper 80. This barrier 31, when integrated into the mechanical energy conversion demonstration device, can also demonstrate the conversion between kinetic energy and elastic potential energy through the collision of the timing ball and the barrier 31 ring, more effectively stimulating public scientific interest and ultimately achieving a better effect in inspiring scientific understanding.

[0055] Based on the above, the ball delivery mechanism 10, as Figure 1 , Figure 7 and Figure 8As shown, the ball delivery mechanism 10 includes a vertically arranged ball delivery tube 13. The lower part of the side wall of the ball delivery tube 13 has a ball inlet 132 communicating with the ball outlet end of the ball receiving track 20, and the upper part of the side wall of the ball delivery tube 13 has a ball outlet 131. The ball outlet 131 is connected to the ball guide assembly 60 via the ball delivery track 30. A spiral conveying rod 14, coaxially rotating inside the ball delivery tube 13, is used to deliver the timing ball to the ball outlet 131. The spiral conveying rod 14 is driven by a gear power unit connected to a servo motor 90, and the time for one rotation of the spiral conveying rod 14 is 30 seconds. Of course, in actual implementation, this time display device can also be used independently without the mechanical energy conversion demonstration device. If the time display device is used alone, the time for one rotation of the spiral conveying rod 14 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, so the time for one rotation of the spiral conveying rod 14 is 1 minute.

[0056] It is worth mentioning that in this application, the servo motor 90 controlling the rotation of the screw conveyor 14, the first drive wheel 613, the second drive wheel 623, and the cam 56 is the same. In actual implementation, such as... Figure 3 As shown, a drive gear 91 is coaxially fixed on the output shaft of the servo motor 90. The drive gear 91 meshes with one of the gear sets 57. Furthermore, a gear linkage mechanism is provided between the gear set 57 that drives the cam 56 and the gear transmission group 63 that drives the first drive wheel 613 and the second drive wheel 623. The transmission ratio between the gear set 57 and the gear transmission group 63 can be controlled to the desired ratio through the gear linkage mechanism. Additionally, as... Figure 7 As shown, a helical gear 141 is coaxially fixed to the lower end of the helical conveying rod 14, and a shaft 111 radially penetrates the side wall of the ball feeding cylinder 13, as shown. Figure 3 As shown, one end of the shaft 111 is coaxially fixed with a ball-feeding bevel gear 12 that meshes with the helical gear 141, and the other end is coaxially fixed with a ball-feeding gear 11 that meshes with the drive 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 helical gear 141 and the drive gear 91 to the required ratio. This method, driven by a servo motor 90, effectively ensures the precise coordination between the various transmission structures, guaranteeing the accuracy of the time display device.
