Description

A launching mechanism for rapidly projecting a circular ring Technical Field

[0001] This invention relates to the field of robotics, and more specifically to a launching mechanism for rapidly projecting a ring. Background Technology

[0002] More and more jobs are now being performed and completed by robots because robots can perform high-intensity and high-efficiency work, and robots are being used in more and more fields.

[0003] With the continuous advancement of robotics technology, various robots have appeared in the public eye, and robot sports competitions have become an indispensable part of robotics events. The "National College Student Robot Competition (Robocon)" is the domestic qualifier for the "Asia-Pacific College Student Robot Competition," an event initiated by the Asian Broadcasting Union (ABU) in 2002 to showcase college student robot design and construction. The competition releases a new set of rules annually, requiring participants to comprehensively utilize mechanical, electronic, and control technologies to complete the tasks set by the rules. It serves as a high-tech robotics competition platform.

[0004] In recent years, the theme of the ABU Robocon competition has been for rabbit and elephant robots to collaborate in scattering flowers over Angkor Wat. The actual competition is a "ring toss game," using rings made of blue and red rubber hoses instead of flowers.

[0005] However, since the game involves throwing more than one ring, and some scenarios require a certain throwing speed, if the launching mechanism is not fast enough, it can slow down the progress of the next throw, leading to unsatisfactory results. Summary of the Invention

[0006] This invention provides a launching mechanism for rapidly projecting a circular ring, which enables the rapid projection of the ring.

[0007] To achieve the above objectives, the technical solution of the present invention is: a launching mechanism for rapidly projecting a circular ring, comprising a launching base, a launching tray, and a launching drive device. The launching drive device includes a driving component, a launching spring, and a releasing component. The driving component is provided on the launching base, the launching spring is provided on the launching base, the launching tray is provided on the launching spring, and the releasing component is provided below the launching base. The driving component drives the releasing component to compress the launching spring, and the releasing component restricts the setting of the compressed launching spring.

[0008] The driving assembly includes a release drive motor and a release base. The release drive motor drives the release base to move. The release assembly includes a release locking plate, a release connecting plate, and a release trigger plate. The center of the release connecting plate is rotatably located at the center of one end of the release base via a first connecting shaft. A second connecting shaft is located at the center of the other end of the release base. The release trigger plate is rotatably located on the second connecting shaft and is in contact with one end of the release connecting plate. A third connecting shaft is located at the other end of the release connecting plate, and the release locking plate is rotatably located on the third connecting shaft. A first spring is located between the release locking plate and the other end of the release connecting plate. A second spring is located between the release connecting plate and the release base. A third spring is located between the release trigger plate and the release base. The third spring drives the release trigger plate to abut against the trigger connecting plate. The second spring drives the trigger connecting plate to press the release trigger plate, thus mutually restricting and fixing the release trigger plate and the release connecting plate. The release locking plate is in contact with the release spring.

[0009] The above structure, when projecting the ring, places the ring onto the launch tray via a transport mechanism, compresses the launch spring via a drive assembly, and releases the spring force via a release assembly, thus launching the ring. The structure is simple and reliable. A release plate restricts and holds the launch spring, allowing it to be compressed by the release drive motor. The structure is simple and effective. The second and third springs ensure proper connection between the release trigger plate and the release connecting plate. The system maintains mutual constraints to achieve rigid balance, ensuring that the release trigger plate, release connecting plate, and release locking plate remain in a fixed state. When release is required, only a small force is applied to the release trigger plate to disrupt the rigid balance between the release trigger plate and the release connecting plate. This releases the constraint of the release connecting plate on the release locking plate, allowing the launching spring to overcome the rigid constraint of the release locking plate and swing the release locking plate forward. When the release locking plate swings forward to a certain angle, the launching spring disengages from the release locking plate, thus rapidly projecting the ring. The structure is simple and stable.

[0010] Furthermore, the drive assembly also includes a release drive driving wheel, a release drive driven wheel, a release drive screw, a release slider, and a release screw nut. A release drive motor is provided at one end of the launching base, and a release drive driving wheel is provided on the drive shaft of the release drive motor. A release drive driven wheel that meshes with the release drive driving wheel is provided at one end of the launching base. One end of the release drive screw is connected to the release drive driven wheel, and the other end of the release drive screw is provided at the other end of the launching base through a release screw bearing. A release screw nut is provided on the release drive screw, and a release guide rail is provided on the launching base. The releasing base is slidably mounted on the release guide rail through a release slider. The releasing base is also connected to the release screw nut, and a release assembly is provided on the releasing base. The release assembly restricts the launching spring.

[0011] This configuration involves using a release drive motor to rotate the release drive screw, which in turn moves the release base mounted on the release slider. This, in turn, compresses the launch spring via the release assembly, thereby providing power for the launch of the ring. The structure is simple and reliable.

[0012] Furthermore, a release limiting groove is provided below the other end of the release connecting plate, and a release limiting rod corresponding to the release limiting groove is provided at the bottom of the release plate. The first spring pulls the release plate downward to swing it so that the release limiting rod abuts against the release limiting groove. Thus, by setting the release limiting groove, the release plate is fixed by the release connecting plate, facilitating the release plate's restriction of the launching spring.

[0013] Furthermore, a release slot is provided on the release trigger plate, and a release thrust bearing corresponding to the release slot is provided at one end of the release connecting plate. The third spring drives the release trigger plate to swing downward so that the release slot abuts against the release thrust bearing. The second spring drives the trigger connecting plate to swing downward so that the release thrust bearing presses down on the bottom of the release slot.

[0014] This design secures the release thrust bearing via the release slot, and the second and third springs ensure that the release trigger plate and the release connecting plate remain mutually restrained to achieve rigid balance. This allows the release trigger plate, release connecting plate, and release card plate to remain in a fixed state, enabling the release assembly to compress the launch spring. The structure is simple and stable.

[0015] Furthermore, a release adjustment assembly is also provided on the launch base. The release adjustment assembly includes a release adjustment motor, a release adjustment lead screw, a release adjustment drive wheel, a release adjustment driven wheel, a release adjustment lead screw nut, a release adjustment slider, a release adjustment guide rail, and a release adjustment rod. The release adjustment motor is located at one end of the launch base. A release adjustment drive wheel is located on the drive shaft of the release adjustment motor. A release adjustment driven wheel that meshes with the release adjustment drive wheel is located at one end of the launch base. One end of the release adjustment lead screw is connected to the release adjustment driven wheel. The other end of the release adjustment lead screw is located at the other end of the launch base through a release adjustment bearing. A release adjustment lead screw nut is located on the release adjustment lead screw. A release adjustment guide rail is located on the launch base. The release adjustment rod is slidably mounted on the release adjustment guide rail through the release adjustment slider. The release adjustment rod is also connected to the release adjustment lead screw nut. The release adjustment rod is in contact with the release trigger plate.

[0016] This configuration involves a release adjustment motor driving a release adjustment screw to rotate, which in turn moves a release adjustment rod mounted on the release adjustment screw nut along the length of the launching base. Once the position of the release adjustment rod is adjusted, the release drive motor moves the release assembly and compresses the launching spring. When the release trigger plate contacts the release adjustment rod, the release assembly continues to move, while the release trigger plate is blocked by the release adjustment rod and cannot move. The release adjustment rod then drives the release trigger plate to swing upward around the second connecting shaft, which in turn pushes the release connecting plate upward. This disrupts the rigid balance between the release trigger plate and the release connecting plate, causing the release trigger plate to swing upward, which in turn drives the release locking plate to swing forward. This causes the release locking plate to disengage from the launching spring, releasing the spring force and launching the ring. By adjusting the position of the release adjustment rod, the compression of the launching spring can be controlled to adjust the launching distance of the ring, facilitating ring throwing in various scenarios during competitions.

[0017] Furthermore, a spring guide shaft is provided on the launching base, and a spring guide plate that slides along the length direction of the spring guide shaft is provided on the spring guide shaft. A launching spring is provided on the spring guide shaft between the spring guide plate and one end of the launching base. The release plate is in contact with the spring guide plate. With this configuration, the spring guide plate can be moved along the length direction of the spring guide shaft by the release component, thereby compressing the launching spring. The structure is simple and effective. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] As shown in Figures 1 to 6, a launching mechanism for rapidly projecting a ring includes a launching base 21, a launching tray 22, and a launching drive device 4. The launching drive device 4 includes a driving component 41, a launching spring 42, and a releasing component 6. The driving component 41 is provided on the launching base 21, the launching spring 42 is provided on the launching spring 42, the launching tray 22 is provided on the launching spring 42, and the releasing component is provided below the launching base. The driving component 41 drives the releasing component 6 to compress the launching spring 42, and the releasing component 6 restricts the setting of the compressed launching spring.

[0026] As shown in Figures 1 and 2, the drive assembly 41 includes a release drive motor 411, a release drive driving wheel 412, a release drive driven wheel 413, a release drive screw 414, a release base 415, a release slider 416, and a release screw nut 417. The release drive motor 411 is located at one end of the launch base 21, and the release drive driving wheel 412 is mounted on the drive shaft of the release drive motor 411. The release drive driven wheel 413, which meshes with the release drive driving wheel 412, is located at one end of the launch base 21. The release drive screw 414... One end of the release drive driven wheel 413 is connected to the release drive screw 414, and the other end of the release drive screw 414 is set at the other end of the launch base 21 through the release screw bearing (not shown in the figure). The release drive screw 414 is provided with a release screw nut 417, and the launch base 21 is provided with a release guide rail 418. The release base 415 is slidably set on the release guide rail 418 through a release slider 416. The release base 415 is also connected to the release screw nut 417. The release base 415 is provided with a release assembly 6, and the release assembly 6 restricts the launch spring.

[0027] With this configuration, the release drive motor 411 drives the release drive screw 414 to rotate, thereby moving the release base 415 set on the release slider 416. This, in turn, drives the release spring 42 to compress via the release assembly 6, thus providing power for the release of the ring. The structure is simple and reliable.

[0028] As shown in Figures 3 and 4, the release assembly 6 includes a release latch plate 61, a release connecting plate 62, and a release trigger plate 63. The center of the release connecting plate 62 is rotatably disposed at the center of one end of the release base 415 via a first connecting shaft 64. A second connecting shaft 65 is disposed at the center of the other end of the release base 415, and the release trigger plate 63 is rotatably disposed on the second connecting shaft 65. The release trigger plate 63 is in contact with one end of the release connecting plate 62. A third connecting shaft 66 is disposed at the other end of the release connecting plate 62, and the release latch plate 61 is rotatably disposed on the third connecting shaft 66. On the connecting shaft 66, a first spring 601 is provided between the other end of the release plate 61 and the release connecting plate 62, a second spring 602 is provided between the release connecting plate 62 and the release base 415, and a third spring 603 is provided between the release trigger plate 63 and the release base 415. The third spring 603 drives the release trigger plate 63 to abut against the trigger connecting plate 62, and the second spring 602 drives the trigger connecting plate 62 to press the release trigger plate 63 so that the release trigger plate 63 and the release connecting plate 62 mutually restrict and fix each other. The release plate 61 is in contact with the launching spring 42.

[0029] This design restricts and locks the launching spring 42 by releasing the locking plate 61, thereby compressing the launching spring 42 under the drive of the release drive motor 411. The structure is simple and effective.

[0030] As shown in Figure 5, a release limiting groove 621 is provided below the other end of the release connecting plate 62, and a release limiting rod 611 corresponding to the release limiting groove 621 is provided at the bottom of the release clamping plate 61. The first spring 601 pulls the release clamping plate 31 to swing downward, causing the release limiting rod 611 to abut against the release limiting groove 621. Thus, the release limiting groove 621 allows the release connecting plate 62 to fix the release clamping plate 61, facilitating the release clamping plate 61's restriction of the launching spring 42.

[0031] As shown in Figure 4, a release slot 631 is provided on the release trigger plate 63, and a release thrust bearing 622 corresponding to the release slot 631 is provided at one end of the release connecting plate 62. The third spring 603 drives the release trigger plate 63 to swing downward so that the release slot 631 abuts against the release thrust bearing 622. The second spring 602 drives the trigger connecting plate 62 to swing downward so that the release thrust bearing 622 presses down on the bottom of the release slot 631.

[0032] This configuration allows the release thrust bearing 622 to be fixed via the release slot 631, and the release trigger plate 63 and release connecting plate 62 to maintain mutual restraint and achieve rigid balance through the action of the second spring 602 and the third spring 603. This ensures that the release trigger plate 63, release connecting plate 62 and release slot 61 remain in a fixed state, thereby enabling the release spring 42 to be compressed via the release assembly 6. The structure is simple and stable.

[0033] As shown in Figures 1 and 6, a release adjustment assembly 7 is also provided on the launch base 21. The release adjustment assembly 7 includes a release adjustment motor 71, a release adjustment lead screw 72, a release adjustment drive wheel 73, a release adjustment driven wheel 74, a release adjustment lead screw nut 75, a release adjustment slider 76, a release adjustment guide rail 77, and a release adjustment rod 78. The release adjustment motor 71 is located at one end of the launch base 21, and the release adjustment drive wheel 73 is provided on the drive shaft of the release adjustment motor 71. A release adjustment mechanism that meshes with the release adjustment drive wheel 73 is provided at one end of the launch base 21. Driven wheel 74, one end of release adjusting screw 72 is connected to release adjusting driven wheel 74, the other end of release adjusting screw 72 is set at the other end of launch base 21 through release adjusting bearing 721, release adjusting screw nut 75 is provided on release adjusting screw 72, release adjusting guide rail 77 is provided on launch base 21, release adjusting rod 78 is slidably set on release adjusting guide rail 77 through release adjusting slider 76, release adjusting rod 78 is also connected to release adjusting screw nut 75, and release adjusting rod 78 is in contact with release trigger plate 63.

[0034] Therefore, the release adjusting motor 71 drives the release adjusting screw 72 to rotate, thereby causing the release adjusting rod 78, which is mounted on the release adjusting screw nut 75, to move along the length of the launching base 21. After the position of the release adjusting rod 78 is adjusted, the release drive motor 411 drives the release assembly 6 to move and compress the launching spring 42. When the release trigger plate 63 contacts the release adjusting rod 78, the release assembly 6 continues to move, while the release trigger plate 63 is blocked by the release adjusting rod 78 and cannot move. Thus, the release adjusting rod 78 drives the release trigger plate 63 to move around the second connecting shaft 65. The fulcrum swings upward, which in turn pushes the release connecting plate 62 to swing upward, thereby disrupting the rigid balance between the release trigger plate 63 and the release connecting plate 62. This causes the release trigger plate 63 to drive the release connecting plate 62 to swing upward, which in turn drives the release locking plate 61 to swing forward, causing the release locking plate 61 to disengage from the launch spring 42. This releases the elastic force of the launch spring 42, thus launching the ring. By adjusting the position of the release adjusting rod 78, the compression degree of the launch spring 42 can be controlled to adjust the launch distance of the ring, facilitating ring throwing in various scenarios during the competition.

[0035] As shown in Figure 1, a spring guide shaft 421 is also provided on the launching base 21. A spring guide plate 422 that slides along the length direction of the spring guide shaft 421 is provided on the spring guide shaft 421. A launching spring 42 is provided on the spring guide shaft 421 between the spring guide plate 421 and one end of the launching base 21. The release plate 41 is in contact with the spring guide plate 422. With this configuration, the spring guide plate 422 can be moved along the length direction of the spring guide shaft 421 by the release component 6, thereby compressing the launching spring 42. The structure is simple and effective.

[0036] The working principle of this invention is as follows: When projecting a ring, the ring is placed on the launch tray by a transport mechanism. A drive assembly compresses the launch spring, which is then released by a release assembly. The ring is thus launched by the spring's elastic force, achieving ring launch. The structure is simple and reliable. A release plate restricts and holds the launch spring, allowing it to be compressed by the release drive motor. This structure is simple and effective. The second and third springs facilitate the release of the trigger plate and the release connecting plate. The system maintains a rigid balance by limiting each other, thus ensuring that the release trigger plate, release connecting plate, and release locking plate remain in a fixed state. When release is required, only a small force is applied to the release trigger plate to disrupt the rigid balance between the release trigger plate and the release connecting plate. This releases the constraint of the release connecting plate on the release locking plate, allowing the launching spring to overcome the rigid constraint of the release locking plate and swing the release locking plate forward. When the release locking plate swings forward to a certain angle, the launching spring disengages from the release locking plate, thereby rapidly projecting the ring. The structure is simple and stable.
