Description

Technical Field

[0001] This invention relates to the field of badminton serving machine technology, and particularly to a serving mechanism and a badminton serving machine. Background Technology

[0002] A badminton serving machine is used to launch badminton shuttlecocks to assist personnel in badminton training. In related technologies, a badminton serving machine includes a shuttlecock supply section, a conveying section, and a serving mechanism. The conveying section transports the shuttlecock from the supply section to the serving mechanism. The serving mechanism consists of two parallel drive discs that rotate in opposite directions. The bottom of the shuttlecock is compressed and accelerated by the opposing frictional forces of the two drive discs, thus being launched at high speed. However, the overall space occupied by the serving mechanism is relatively large, making the storage and transportation of the machine inconvenient and affecting the user experience. Summary of the Invention

[0003] The main objective of this invention is to provide a serving mechanism and a badminton serving machine, aiming to solve the technical problems of inconvenient storage and transportation of the serving machine.

[0004] To achieve the above objectives, a first aspect of the present invention provides a serving mechanism, the serving mechanism comprising: A throwing stick has a first end and a second end opposite to each other along a first direction, the throwing stick including a positioning structure located at the first end, the positioning structure being adapted to position a badminton shuttlecock to be thrown; A drive assembly is connected to the throwing rod and configured to drive the throwing rod to rotate about a first axis in a first circumferential direction, the first axis being perpendicular to the first direction; During the process of the throwing rod rotating along the first circumferential direction, the positioning structure moves from the first position to the second position along the first circumferential direction, and the positioning structure drives the badminton shuttlecock located at the first position to the second position and throws it out.

[0005] In some embodiments, the positioning structure includes a clamping portion configured to clamp the shuttlecock at a first position and release the shuttlecock at a second position; or, The throwing rod includes a first rod and a second rod arranged at intervals along a direction parallel to the first axis. The end of the first rod at the first end is a first clamping end, and the end of the second rod at the first end is a second clamping end. The first clamping end and the second clamping end together form the positioning structure. The first clamping end and the second clamping end are configured to clamp the shuttlecock together at the first position and release the shuttlecock at the second position.

[0006] In some embodiments, the serving mechanism further includes a guiding mechanism configured to guide the first rod and the second rod to rotate about a second axis intersecting the first axis, such that the distance between the first clamping end and the second clamping end at the first position is smaller than the distance at the second position.

[0007] In some embodiments, the first axis is located between the first end and the second end along the first direction; The guiding mechanism includes a guide member, which is provided with a first guide groove and a second guide groove. The end of the first rod at the second end is a first guide end, which extends into the first guide groove. The end of the second rod at the second end is a second guide end, which extends into the second guide groove. When the throwing rod rotates around the first axis, the first guide end slides in the first guide groove and the second guide end slides in the second guide groove. When the positioning structure is in the first position, the distance between the first guide end and the second guide end is a first distance. When the positioning structure is in the second position, the distance between the first guide end and the second guide end is a second distance. The first distance is greater than the second distance.

[0008] In some embodiments, the first rod includes a first rod body, the first guide end includes a first guide extending into the first guide groove and a first elastic member connecting the first guide and the first rod body respectively, the first guide being slidably connected to the first rod body so as to be able to slide along the length direction of the first rod body; And / or, The second rod includes a second rod body, and the second guide end includes a second guide body extending into the second guide groove and a second elastic member connecting the second guide body and the second rod body respectively. The second guide body is slidably connected to the second rod body so as to be able to slide along the length direction of the second rod body. And / or, The guiding mechanism further includes a return spring, which is located between the first rod and the second rod and is respectively connected to the ends of the first rod and the second rod at the second end.

[0009] In some embodiments, the drive assembly includes a first drive unit, the first drive unit including an elastic drive member connected to the throwing rod, and when the throwing rod rotates about the first axis in a second circumferential direction opposite to the first circumferential direction, the elastic drive member gradually stores energy to generate a driving force that drives the throwing rod to rotate in the first circumferential direction.

[0010] In some embodiments, the first drive unit further includes a first track defining an arcuate groove extending at least partially along the first circumferential direction, the resilient drive member being located within the arcuate groove; The throwing rod includes a connecting shaft that extends in a direction parallel to the first axis. The connecting shaft is connected to a driving block that extends into the arc-shaped groove and is connected to the elastic driving member. The elastic driving member drives the driving block, thereby driving the connecting shaft to rotate in the first circumferential direction, and thus driving the positioning structure to move from the first position to the second position.

[0011] In some embodiments, the drive assembly further includes a second drive unit, which is connected to the throwing rod and drives the throwing rod to move along the second circumferential direction, and the second drive unit is capable of releasing the drive of the throwing rod when the positioning structure is in the first position; The second drive unit includes a drive motor and a transmission mechanism. The transmission mechanism is connected to the drive motor and the throwing rod respectively. The transmission mechanism has a first state of being connected to the throwing rod and a second state of being disconnected from the throwing rod. In the first state, the throwing rod moves along the second circumferential direction, and in the second state, the throwing rod moves along the first circumferential direction.

[0012] In some embodiments, the transmission mechanism includes a first gear and a second gear, the first gear being connected to the connecting shaft, and the second gear periodically meshing with the first gear and being driven by the drive motor; During the process of the drive motor driving the second gear to rotate along the first circumferential direction, the second gear meshes with the first gear, thereby driving the throwing rod to rotate along the second circumferential direction. After the throwing rod is driven to the positioning structure being in the first position, the first gear and the second gear disengage, thereby driving the throwing rod to rotate along the first circumferential direction by the elastic drive member. After the throwing rod is driven to the positioning structure being in the second position, the first gear and the second gear re-mesh.

[0013] A second aspect of the present invention provides a badminton serving machine, the badminton serving machine comprising: The ball-serving mechanism described in the above embodiments; It also includes a shuttlecock storage cylinder and a feeding drive mechanism. The shuttlecock storage cylinder is used to store a plurality of the shuttlecocks, and the feeding drive mechanism is used to drive each of the shuttlecocks to move so that at least one of the shuttlecocks is held in a position that can be positioned by the positioning structure located in the first position.

[0014] Compared with the prior art, the beneficial effects of the present invention include: In the technical solution of this invention, the serving mechanism includes a throwing rod and a driving assembly. The throwing rod has a first end and a second end that are opposite to each other along a first direction. The throwing rod includes a positioning structure located at the first end, which can position the shuttlecock to be thrown. In the prior art, the serving mechanism consists of two driving discs arranged parallel to each other and capable of rotating in opposite directions. The bottom of the shuttlecock can be squeezed and accelerated by the opposing frictional forces of the two driving discs, and thus be launched at high speed. However, the overall space occupied by the serving mechanism is relatively large. In this solution, the driving assembly is connected to the throwing rod and configured to drive the throwing rod to rotate around a first axis along a first circumferential direction. During the rotation of the throwing rod along the first circumferential direction, the positioning structure moves from a first position to a second position along the first circumferential direction, and the positioning structure drives the shuttlecock located at the first position to the second position and throws it out. That is, this solution achieves the serving by driving the throwing rod to rotate through the driving assembly, thereby throwing the shuttlecock out. Compared with the disc-type serving mechanism of the prior art, the throwing-type serving mechanism of this solution can effectively reduce the overall space occupied by the serving mechanism, facilitate the storage and transportation of the serving machine, and improve the user experience. Furthermore, existing disc-type serving mechanisms, after being squeezed and rubbed by the double discs, exhibit strong self-spinning, resulting in a flight trajectory that differs from the actual flight characteristics of a badminton shuttlecock (especially forecourt shots or drop shots). In contrast, the tossing serving mechanism of this design throws the shuttlecock through rotation, resulting in weaker self-spinning and a more natural flight trajectory. This means the shuttlecock served by this design more closely resembles the motion of a human hand striking the shuttlecock. Therefore, it offers significant advantages for training players in developing their feel for receiving serves and for simulating different shot trajectories (such as high clears and flat drives).

[0018] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0019] 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 a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0020] The first aspect of this invention provides a serving mechanism 10 for tossing a badminton shuttlecock 20. This serving mechanism 10 has a small overall volume, facilitating storage and transportation. It should be noted that the serving mechanism 10 is used in a badminton serving machine 1. The following refers to... Figures 1 to 10 The following describes the ball-serving mechanism 10 according to an embodiment of this application. Specifically, the ball-serving mechanism 10 includes a throwing rod 100 and a drive assembly 200.

[0021] Reference Figures 1 to 4 The throwing rod 100 is used to throw the badminton shuttlecock 20. To facilitate the description and understanding of the specific structure of the throwing rod 100, a first direction X is defined, referring to... Figure 4 The orientation, from the lower left to the upper right, is the first direction X. The throwing rod 100 has a first end 110 and a second end 120 that are opposite each other along the first direction X, as shown in the reference... Figure 4 Regarding orientation, the right end of the throwing rod 100 can be the first end 110, and the left end can be the second end 120. The throwing rod 100 has a positioning structure 130, which is located at the first end 110 of the throwing rod 100. The positioning structure 130 is used to position the shuttlecock 20 to be thrown, so that the shuttlecock 20 can be stably held in the target position before being thrown, thereby improving the accuracy of the throw.

[0022] It is understood that during the throwing process, the positioning structure 130 can position a single shuttlecock 20 at a time. After a single throwing operation is completed, the shuttlecock 20 can be replenished in various ways. Specifically, in some embodiments, the remaining shuttlecock 20 can be fed to the positioning structure 130 one by one by the feeding drive mechanism 40 to realize the next throwing operation. In other embodiments, the remaining shuttlecock 20 can also be manually fed to the positioning structure 130 to realize the next throwing operation. This application embodiment uses the replenishment of shuttlecock 20 to the positioning structure 130 by the feeding drive mechanism 40 as an example for illustration.

[0023] Reference Figure 2 , Figures 4 to 6 The positioning structure 130 is described below for positioning the shuttlecock 20. In some embodiments, the positioning structure 130 can clamp the shuttlecock 20 to achieve positioning. In other embodiments, the positioning structure 130 can lift and hold the shuttlecock 20 (e.g., by providing a connecting hole or connecting groove, the head of the shuttlecock 20 can be held in the connecting hole or connecting groove) to achieve positioning. In other embodiments, the positioning structure 130 can adsorb the shuttlecock 20 (e.g., by air pressure adsorption) to achieve positioning. The specific positioning setting of the positioning structure 130 for the shuttlecock 20 can be determined according to the actual situation. This application embodiment uses the positioning structure 130 clamping the shuttlecock 20 as an example for explanation.

[0024] Reference Figures 4 to 6 The drive assembly 200 is used to drive the throwing rod 100 to move, thereby realizing the throwing operation. The drive assembly 200 is connected to the throwing rod 100. Specifically, in some embodiments, the drive assembly 200 may be connected to the middle position of the throwing rod 100 near the second end 120 and away from the first end 110. In other embodiments, the drive assembly 200 may be connected to the second end 120 of the throwing rod 100. In other embodiments, the drive assembly 200 may be connected to the middle position of the throwing rod 100 near the first end 110 and away from the second end 120. In still other embodiments, the drive assembly 200 may be connected to the middle position of the throwing rod 100 along the first direction X. This application embodiment uses the example of the drive assembly 200 being connected to the middle position of the throwing rod 100 near the second end 120 and away from the first end 110 to drive the throwing rod 100 to rotate as an example.

[0025] To facilitate the description and understanding of the driving process of the drive assembly 200 on the throwing rod 100, a first axis 101 is defined, which is perpendicular to the first direction X. In some embodiments, reference is made to... Figure 4In terms of orientation, the first axis 101 can extend in a horizontal front-to-back direction. In some embodiments, the first axis 101 can also extend obliquely in a direction inclined to the horizontal direction. In other embodiments, the first axis 101 can extend vertically perpendicular to the horizontal direction. The specific extension direction of the first axis 101 can be determined according to the actual serving requirements. For example, the serving machine can simulate the initial serve, or it can simulate a mid-course drop shot (the shuttlecock 20 is launched from the lower left end of the net to the lower right end of the net), etc. In this embodiment, the first axis 101 extending in a horizontal front-to-back direction is used as an example for explanation.

[0026] The following describes the driving process of the drive assembly 200 on the throwing rod 100. The drive assembly 200 can drive the throwing rod 100 to rotate around the first axis 101 in the first circumferential direction to achieve the throwing operation. (Refer to...) Figure 6 In terms of orientation, the drive assembly 200 can drive the throwing rod 100 to rotate counterclockwise around the first axis 101 to achieve the throwing operation. During the rotation of the throwing rod 100 along the first circumferential direction, the positioning structure 130 moves from a first position to a second position along the first circumferential direction, and the positioning structure 130 drives the shuttlecock 20 located at the first position to the second position and throws it. It should be noted that the first position can be the initial position where the positioning structure 130 positions the shuttlecock 20. At this time, the throwing rod 100 can extend horizontally or obliquely. The second position is the position where the shuttlecock 20 leaves the positioning structure 130. At this time, the throwing rod 100 can extend vertically or obliquely, depending on the actual structure and serving requirements. It can be understood that the shuttlecock 20 can leave the throwing rod 100 before the throwing rod 100 reaches the vertical position. When the throwing rod 100 opens in advance to release the shuttlecock 20, the second position is the position before the throwing rod 100 is in the vertical position.

[0027] It should be noted that in some embodiments, the second end 120 of the throwing rod 100 may also be equipped with a torsion spring. The throwing rod 100 can be manually bent from vertical to horizontal and locked, and then the shuttlecock 20 can be placed in the positioning structure 130. Finally, it is electrically released, and the shuttlecock 20 is launched by the elastic force accumulated by the torsion spring. Before the next launch of the shuttlecock 20, the lever can also be manually bent to complete the pre-launch preparation.

[0028] The positioning structure 130 can launch the shuttlecock 20 in multiple ways. (See reference...) Figures 4 to 6In some embodiments, when the positioning structure 130 clamps the shuttlecock 20 to achieve positioning, the throwing rod 100 can open to release the shuttlecock 20. In other embodiments, when the positioning structure 130 uses air pressure to adsorb the shuttlecock 20 to achieve positioning, the throwing rod 100 can stop adsorption to release the shuttlecock 20. In other embodiments, when the positioning structure 130 holds the shuttlecock 20 in place to achieve positioning, the shuttlecock 20 can be pushed against by the movable part to detach it from the positioning structure 130 and then released. This application embodiment uses the example of the throwing rod 100 opening to release the shuttlecock 20 as an example.

[0029] It should be noted that the rotation range of the throwing rod 100 after being driven by the drive component 200 can be determined according to the actual situation. That is, the serving mechanism 10 can change the rotation angle of the throwing rod 100, thereby adjusting the position of the positioning structure 130 of the throwing rod 100, thereby changing the throwing angle and direction of the serving mechanism 10, which can adapt to the serving needs of various angles, and the adjustment of the throwing position is convenient and quick.

[0030] In the technical solution of this invention, the serving mechanism 10 includes a throwing rod 100 and a drive assembly 200. The throwing rod 100 has a first end 110 and a second end 120 that are opposite to each other along a first direction X. The throwing rod 100 includes a positioning structure 130 located at the first end 110, which can position the badminton shuttlecock 20 to be thrown. In the prior art, the serving mechanism consists of two drive discs arranged parallel to each other and rotatable in opposite directions. The bottom head of the badminton shuttlecock can be squeezed and accelerated by the opposing frictional forces of the two drive discs, and thus be launched at high speed. However, the overall space occupied by the serving mechanism is relatively large. In this solution, the drive assembly 200 is connected to the throwing rod 100 and configured to drive the throwing rod 100 to rotate around a first axis 101 in a first circumferential direction. During the rotation of the throwing rod 100 along the first circumference, the positioning structure 130 moves from the first position to the second position along the first circumference, and the positioning structure 130 drives the shuttlecock 20 located at the first position to the second position and throws it out. That is, this solution uses the driving component 200 to drive the throwing rod 100 to rotate and then throw the shuttlecock 20 out to achieve the serve. Compared with the existing disc-type serving mechanism, the throwing-type serving mechanism 10 of this solution can effectively reduce the overall space occupied by the serving mechanism 10, making it convenient for the serving machine to be stored and transported, and improving the user experience. Furthermore, the existing disc-type serving mechanism will have a strong self-rotation after being squeezed by the friction of the two discs, and its flight trajectory is different from the flight characteristics of the actual badminton hit (especially the forecourt shuttlecock or drop shot). The tossing-type serving mechanism 10 of this solution can throw the shuttlecock 20 by rotating it. The shuttlecock 20 has a weaker self-rotation and a more natural flight trajectory. That is, the shuttlecock 20 launched by the serving mechanism 10 of this solution is closer to the motion state of a human hand hitting the shuttlecock. Therefore, it has significant advantages for training the trainee to develop the feel of receiving the serve and for simulating different ball trajectories (such as high clear, flat drive, etc.).

[0031] Reference Figures 4 to 6 The specific configuration of the throwing rod 100 is described below. In some embodiments, the throwing rod 100 includes a first rod 140 and a second rod 150, which are arranged at intervals along a direction parallel to the first axis 101. (Refer to...) Figure 4 Regarding orientation, the front member of the throwing rod 100 can be a first member 140, and the rear member of the throwing rod 100 can be a second member 150. The structure of the second member 150 can be the same as or different from that of the first member 140. It should be noted that the end of the first end 110 of the first member 140 can be a first clamping end 141, and the end of the first end 110 of the second member 150 can be a second clamping end 151, as shown in the reference. Figure 4The orientation, that is, the right end of the first rod 140 is the first clamping end 141, and the right end of the second rod 150 is the second clamping end 151. The first clamping end 141 and the second clamping end 151 together form a positioning structure 130 to clamp and position the shuttlecock 20. (Refer to...) Figure 4 When the positioning structure 130 is in the first position, the first clamping end 141 and the second clamping end 151 jointly clamp the badminton shuttlecock 20. (Refer to 4 to...) Figure 6 When the positioning structure 130 switches from the first position to the second position, the first clamping end 141 and the second clamping end 151 can move away from each other to release the shuttlecock 20.

[0032] In some embodiments, the positioning structure 130 includes a clamping part 131 for clamping the shuttlecock 20. Specifically, the clamping part 131 can clamp the head of the shuttlecock 20, or it can clamp the loops or shafts of the shuttlecock 20, etc. This embodiment of the application uses the clamping part 131 clamping the head of the shuttlecock 20 as an example for explanation. When the positioning structure 130 is in the first position, the clamping part 131 can clamp the shuttlecock 20. When the positioning structure 130 is in the second position, the clamping part 131 can release the shuttlecock 20, that is, the throwing rod 100 can throw the shuttlecock 20 to achieve a serve. It should be noted that the clamping part 131 can be connected to the throwing rod 100. The clamping part 131 includes a first clamping block and a second clamping block. The first clamping block can be close to the second clamping block to clamp the shuttlecock 20, and the first clamping block can be far away from the second clamping block to release the shuttlecock 20.

[0033] In other embodiments, the positioning structure 130 includes an adsorption section. When the positioning structure 130 is in a first position, the adsorption section can use pneumatic pressure to adsorb the badminton shuttlecock 20 to achieve positioning of the shuttlecock 20. When the positioning structure 130 is in a second position, the adsorption section can stop adsorption to achieve throwing of the badminton shuttlecock 20. This application embodiment uses the positioning structure 130 including a first clamping end 141 and a second clamping end 151 to describe the positioning and release of the badminton shuttlecock 20 as an example.

[0034] Reference Figures 2 to 6The specific motion settings of the first rod 140 and the second rod 150 are described below. In some embodiments, the serving mechanism 10 further includes a guiding mechanism 300. The guiding mechanism 300 is used to define the movement trajectories of the first rod 140 and the second rod 150. To facilitate the description and understanding of the specific motion state of the throwing rod 100, a second axis is defined, which intersects the first axis 101. Specifically, the second axis can be perpendicular to the first axis 101, or it can be at other non-perpendicular angles to the first axis 101. In this embodiment, the second axis is perpendicular to the first axis 101 as an example. The guiding mechanism 300 can guide the first rod 140 and the second rod 150 to rotate around the second axis, so that the distance between the first clamping end 141 and the second clamping end 151 at the first position is smaller than the distance at the second position (i.e., the first rod 140 and the second rod 150 swing relative to each other). In other words, the guiding mechanism 300 can guide the first rod 140 and the second rod 150 to rotate around the second axis to open and close, thereby releasing and clamping the shuttlecock 20. Since the first rod 140 and the second rod 150 can rotate synchronously around the first axis 101 to achieve the pre-throwing operation of the shuttlecock 20, the overall serving process of the serving mechanism 10 of this solution is smooth, which can ensure the quality of the serve and improve the training effect.

[0035] Reference Figure 4 The specific configuration of the guide mechanism 300 is described below. In some embodiments, along the first direction X, the first axis 101 is located between the first end 110 and the second end 120, as shown in the figure. Figure 4 The orientation, that is, along the left and right direction, is that the first axis 101 is located between the first end 110 and the second end 120. The throwing rod 100 can rotate around the first axis 101 in the first circumferential direction, that is, when the throwing rod 100 rotates, it can act as a lever to throw the badminton shuttlecock 20.

[0036] Reference Figure 3 In some embodiments, the guiding mechanism 300 includes a guide member 310, which is provided with a first guide groove 311 and a second guide groove 312, as shown in the figure. Figure 3 In terms of orientation, the groove on the front side of the guide member 310 can be a first guide groove 311, and the groove on the rear side of the guide member 310 can be a second guide groove 312. Both the first guide groove 311 and the second guide groove 312 are arranged facing the throwing rod 100, and their structures are arranged opposite each other. The end of the second end 120 of the first rod 140 is the first guide end 142, and the end of the second end 120 of the second rod 150 is the second guide end 152. (Refer to...) Figure 4In terms of orientation, the left end of the first rod 140 is the first guide end 142, and the left end of the second rod 150 is the second guide end 152. The first guide end 142 can extend into the first guide groove 311, and the second guide end 152 can extend into the second guide groove 312.

[0037] When the throwing rod 100 rotates about the first axis 101, the first guide end 142 can slide within the first guide groove 311, and the second guide end 152 can slide within the second guide groove 312. Furthermore, referring to… Figure 4 When the positioning structure 130 is in the first position, the distance between the first guide end 142 and the second guide end 152 is the first distance. (Refer to...) Figure 6 When the positioning structure 130 is in the second position, the distance between the first guide end 142 and the second guide end 152 is the second distance. The first distance is greater than the second distance, meaning that the first guide groove 311 and the second guide groove 312 of this solution can limit the rotation trajectory of the first rod 140 and the second rod 150 along the second axis, allowing the first guide end 142 and the second guide end 152 to move relatively closer and relatively farther apart. This, in turn, allows the first clamping end 141 and the second clamping end 151 to move relatively closer and relatively farther apart, thus enabling the throwing rod 100 to position and release the shuttlecock 20, completing the serving operation of the shuttlecock 20.

[0038] In other embodiments, the guiding mechanism 300 includes a first rod group and a second rod group. The first rod group includes a first rod and a second rod arranged at intervals from each other. Both the first and second rods can be curved rods, and the interval between the first and second rods can define a first guide groove 311. The second rod group includes a third rod and a fourth rod arranged at intervals from each other. Both the third and fourth rods can be curved rods, and the interval between the third and fourth rods can define a second guide groove 312. It can be understood that the first guide end 142 and the second guide end 152 of the throwing rod 100 can slide within the first guide groove 311 and the second guide groove 312, respectively, to realize the positioning and release operation of the shuttlecock 20. This application embodiment uses the guiding mechanism 300 including a guide member 310, with the guide member 310 having a first guide groove 311 and a second guide groove 312, as an example for description.

[0039] Reference Figure 7 and Figure 8The specific structure of the first rod 140 is described below. In some embodiments, the first rod 140 includes a first rod body 143. The first guide end 142 includes a first guide body 1421 and a first elastic member 1422. The first guide body 1421 can extend into the first guide groove 311, and the first elastic member 1422 connects the first guide body 1421 and the first rod body 143. The first guide body 1421 and the first rod body 143 are slidably connected so as to slide along the length direction of the first rod body 143. In this solution, the first guide body 1421 and the first rod body 143 are elastically connected, which can effectively absorb the impact load and manufacturing error during the rotation of the rod, avoid jamming and wear caused by rigid connection, and improve the smoothness of the mechanism's movement and service life.

[0040] The specific structure of the second rod 150 is described below. In some embodiments, the structure of the second rod 150 can be the same as that of the first rod 140. Similarly, the second rod 150 includes a second rod body 153. The second guide end 152 includes a second guide body 1521 and a second elastic member. The second guide body 1521 can extend into the second guide groove 312, and the second elastic member connects the second guide body 1521 and the second rod body 153. The second guide body 1521 and the second rod body 153 are slidably connected so as to slide along the length direction of the second rod body 153. The second guide body 1521 and the second rod body 153 are elastically connected in this solution, which can effectively absorb the impact load and manufacturing error during the rotation of the rod, avoid jamming and wear caused by rigid connection, and improve the smoothness of movement and service life of the mechanism.

[0041] Reference Figure 5 and Figure 8 In some embodiments, the guide mechanism 300 further includes a return spring 320. The return spring 320 is located between the first rod 140 and the second rod 150, and the return spring 320 is connected to the ends of the second ends 120 of the first rod 140 and the second rod 150, respectively. In other words, the return spring 320 is connected to the first guide end 142 and the second guide end 152, respectively. That is, when the throwing rod 100 switches from the second position to the first position, the return spring 320 can help the first guide end 142 and the second guide end 152 of the throwing rod 100 to move away from each other, thereby allowing the first clamping end 141 and the second clamping end 151 to move closer together. This improves the stability and reliability of the clamping part 131 in clamping the shuttlecock 20, avoids the shuttlecock 20 from accidentally detaching from the throwing rod 100 before reaching the target position, and improves the accuracy and reliability of the shuttlecock 20 throwing.

[0042] Reference Figure 4 , Figure 6 and Figure 9The specific configuration of the drive assembly 200 is described below. In some embodiments, the drive assembly 200 includes a first drive unit 210, which drives the throwing rod 100 to switch from a first position to a second position, thereby completing the rotational throwing operation of the throwing rod 100. Specifically, the first drive unit 210 includes an elastic drive member 211, which is connected to the throwing rod 100. For ease of description and understanding, a second circumferential direction is defined, which is opposite to the direction of the first circumferential direction. When the throwing rod 100 rotates around the first axis 101 along the second circumferential direction, refer to... Figure 9 The orientation refers to the direction in which the throwing rod 100 rotates clockwise around the first axis 101. The elastic drive member 211 can gradually store energy to generate a driving force that drives the throwing rod 100 to rotate in the first circumferential direction. It can be understood that the elastic drive member can drive the throwing rod 100 to rotate by compressing and storing energy, or by stretching and storing energy. This embodiment uses the compression storage of energy by the elastic drive member 211 as an example for illustration.

[0043] Reference Figures 4 to 6 It should be noted that in some embodiments, the drive assembly 200 may be provided with a single first drive unit 210. In other embodiments, the drive assembly 200 may be provided with multiple first drive units 210. This application embodiment is described using two first drive units 210 as an example. The drive assembly 200 of this solution can further improve the stability and reliability of the throwing rod 100's rotation and throwing.

[0044] Reference Figure 4 , Figure 6 and Figure 9 The specific driving configuration of the first drive unit 210 for the throwing rod 100 is described below. In some embodiments, the first drive unit 210 further includes a first track 212, which defines an arcuate groove 2121. The arcuate groove 2121 extends at least partially along a first circumferential direction, as shown in the figure. Figure 9 The arc-shaped groove 2121 can extend counterclockwise, and the specific extension length of the arc-shaped groove 2121 can be determined according to the actual situation. The elastic drive element 211 can be set in the arc-shaped groove 2121.

[0045] Reference Figure 4 , Figure 6 and Figure 9 The throwing rod 100 includes a connecting shaft 160, which extends in a direction parallel to the first axis 101, as shown in the figure. Figure 4The connecting shaft 160 extends from the upper left to the lower right. The connecting shaft 160 connects to a drive block 170, which extends into the arc-shaped groove 2121 and connects to an elastic drive member 211. The elastic drive member 211 can drive the connecting shaft 160 to rotate along the first circumferential direction by driving the drive block 170, thereby driving the positioning structure 130 to move from the first position to the second position. It can be understood that when the drive assembly 200 includes two first drive parts 210, each end of the connecting shaft 160 can be connected to a drive block 170, and the two elastic drive members 211 in the two arc-shaped grooves 2121 can drive each drive block 170 to rotate, thereby causing the connecting shaft 160 to rotate along the first circumferential direction, and thus driving the positioning structure 130 to move from the first position to the second position to achieve throwing. This solution can further improve the stability and reliability of the throwing motion driven by the drive assembly 200.

[0046] Reference Figure 7 and Figure 10 The specific configuration of the drive assembly 200 is described below. In some embodiments, the drive assembly 200 includes a second drive unit 220, which drives the throwing rod 100 to switch from a second position to a first position, thereby resetting the throwing rod 100 and preparing it for the next throwing operation. Specifically, the second drive unit 220 is connected to the throwing rod 100 and can drive the throwing rod 100 to move along a second circumferential direction, as shown below. Figure 10 In terms of orientation, the second drive unit 220 can drive the throwing rod 100 to rotate clockwise. Furthermore, the second drive unit 220 can disengage the throwing rod 100 when the positioning structure 130 is in the first position. In other words, when the positioning structure 130 is in the first position, the second drive unit 220 no longer generates driving force on the throwing rod 100, allowing the first drive unit 210 to normally drive the throwing rod 100 from the first position to the second position to complete the throwing operation. In other embodiments, when the positioning structure 130 is in the first position, the second drive unit 220 can also maintain driving force on the throwing rod 100. This application embodiment is described using the example of the second drive unit 220 disengaging the throwing rod 100 when the positioning structure 130 is in the first position.

[0047] Reference Figure 7 and Figure 10 In some embodiments, the second drive unit 220 includes a drive motor 221 and a transmission mechanism 222. The second drive unit 220 includes a drive motor 221 and a transmission mechanism 222. The transmission mechanism 222 is connected to both the drive motor 221 and the throwing rod 100. The transmission mechanism 222 has a first state and a second state. When in the first state, the transmission mechanism 222 is connected to the throwing rod 100, and the throwing rod 100 can move along a second circumferential direction, as shown in the figure. Figure 10The orientation, i.e., the transmission mechanism 222 can drive the throwing rod 100 to rotate clockwise, switching from the second position to the first position to achieve a reset. When in the second state, the transmission mechanism 222 is disconnected from the throwing rod 100, allowing the throwing rod 100 to move along the first circumferential direction, as shown in the reference... Figure 10 The first drive unit 210 can drive the throwing rod 100 to rotate counterclockwise, switching from the first position to the second position to perform the throwing operation. The second drive unit 220 of this solution can stably drive the throwing rod 100 to move along the second circumferential direction to achieve reset, preparing for the next serve, thus effectively improving the continuity and reliability of the serve mechanism 10.

[0048] Reference Figure 7 and Figure 10 In some embodiments, the transmission mechanism 222 includes a first gear 2221 and a second gear 2222, which have different structures. The first gear 2221 can be a sector gear. The first gear 2221 is connected to the connecting shaft 160, meaning the transmission mechanism 222 can drive the first rod 140 and the second rod 150 to rotate synchronously. The second gear 2222 periodically meshes with the first gear 2221 and is driven by the drive motor 221, meaning the drive motor 221 can drive the second gear 2222 to rotate, and the second gear 2222 drives the first gear 2221 to rotate, thereby causing the throwing rod 100 connected to the connecting shaft 160 to rotate. Specifically, during the process of the drive motor 221 driving the second gear 2222 to rotate in the first circumferential direction, the second gear 2222 meshes with the first gear 2221, thereby driving the throwing rod 100 to rotate in the second circumferential direction, as shown in the figure. Figure 10 The orientation, i.e., the transmission mechanism 222 can drive the throwing rod 100 to rotate clockwise. When the throwing rod 100 is driven to the positioning structure 130 in the first position, the first gear 2221 and the second gear 2222 disengage, thereby causing the throwing rod 100 to be driven by the elastic drive member 211 to rotate in the first circumferential direction, as shown in the reference. Figure 10 The orientation, i.e., the elastic drive member 211 can drive the throwing rod 100 to rotate counterclockwise. After the throwing rod 100 is driven to the positioning structure 130 in the second position, the first gear 2221 and the second gear 2222 re-mesh. This solution enables the second drive unit 220 to periodically drive the throwing rod 100, allowing the serving mechanism 10 to continuously perform serving operations, improving the continuity and reliability of the serve.

[0049] Reference Figure 1 and Figure 2In some embodiments, the serving mechanism 10 further includes a housing assembly for assembling and protecting the throwing rod 100 and the drive assembly 200. This housing assembly reduces the entry of foreign objects or dust into the serving mechanism 10, ensuring the stability and reliability of the serve and extending its service life. Specifically, the serving assembly may include a top shell 410, a first side shell 420, and a second side shell 430. (Refer to...) Figure 2 In terms of orientation, the top shell 410 can be the shell on the upper side of the serving mechanism 10, the first side shell 420 can be the shell on the front side of the serving mechanism 10, and the second side shell 430 can be the shell on the rear side of the serving mechanism 10. The specific structure and size of the shell assembly can be determined according to the actual situation.

[0050] Reference Figure 1 and Figure 2 A second aspect of this invention provides a badminton serving machine 1, which includes a serving mechanism 10, a shuttlecock storage cylinder 30, and a feed drive mechanism 40 as described in the above embodiments. The shuttlecock storage cylinder 30 is used to store multiple shuttlecocks 20, as shown in the figure. Figure 1 In terms of orientation, multiple shuttlecocks 20 can be stacked vertically along the storage cylinder 30. The feed drive mechanism 40 drives the movement of each shuttlecock 20, ensuring that at least one shuttlecock 20 is held in a position that can be positioned by the positioning structure 130 in the first position, thus enabling continuous feeding of the shuttlecocks 20 and ensuring the continuity of the serve. Furthermore, the throwing-type serving mechanism 10 of this solution effectively reduces the overall space occupied by the serving mechanism 10, facilitating storage and transportation of the serving machine and improving the user experience. Further, existing disc-type serving mechanisms, after being rubbed and squeezed by the double discs, exhibit strong self-rotation, and their flight trajectory differs from the actual flight characteristics of a badminton shuttlecock (especially forecourt shots or drop shots). The tossing-type serving mechanism 10 of this solution can throw the shuttlecock 20 by rotating it. The shuttlecock 20 has a weaker self-rotation and a more natural flight trajectory. That is, the shuttlecock 20 launched by the serving mechanism 10 of this solution is closer to the motion state of a human hand hitting the shuttlecock. Therefore, it has significant advantages for training the trainee to develop the feel of receiving the serve and for simulating different ball trajectories (such as high clear, flat drive, etc.).

[0051] Reference Figure 1 In some embodiments, the badminton serving machine 1 further includes a support 50, which keeps the serving mechanism 10 at the target height, thus adapting to serving needs in various scenarios and improving the user experience. In other embodiments, the support 50 includes a bracket, which can be folded and stored in the ball storage cylinder 30 during transportation, further reducing the vertical space occupied by the badminton serving machine 1, facilitating storage and transportation, and improving the user experience.

[0052] The following describes the specific usage process of a badminton serving machine 1 according to an embodiment of this application. First, the support part 50 is disengaged from the shuttlecock storage cylinder 30, and multiple shuttlecocks 20 are added to the storage cylinder 30. Then, the support part 50 is opened, thus supporting the serving mechanism 10 at the target height. Second, the first clamping end 141 and the second clamping end 151 of the throwing rod 100 clamp the shuttlecock 20, unlocking the serving mechanism 10. This allows the first driving part 210 of the driving assembly 200 to drive the throwing rod 100 to rotate around the first axis 101 in the first circumferential direction. Specifically, refer to... Figure 4 The elastic drive member 211 located in the arc-shaped groove 2121 of the first track 212 drives the drive block 170. The drive block 170 drives the connecting shaft 160 of the throwing rod 100 to rotate counterclockwise around the first axis 101, so that the positioning structure 130 of the throwing rod 100 switches from the first position to the second position. During the rotation of the throwing rod 100, because the first guide end 142 and the second guide end 152 of the throwing rod 100 extend into the first guide groove 311 and the second guide groove 312 of the guide member 310 respectively, and the second distance between the two guide ends of the positioning structure 130 in the second position is less than the first distance between the two guide ends in the first position, the guiding mechanism 300 can guide the first rod 140 and the second rod 150 to swing and open relative to each other, so that the shuttlecock 20 can be released from the positioning structure 130 to achieve the serve. Thirdly, after the serving mechanism 10 completes the serve, the second drive unit 220 of the drive assembly 200 can drive the throwing rod 100 to rotate around the first axis 101 in the second circumferential direction to achieve a reset, in preparation for the next serve. Specifically, refer to... Figure 4 and Figure 6 The drive motor 221 can drive the second gear 2222 to rotate counterclockwise, and the second gear 2222 meshes with the first gear 2221, that is, the first gear 2221 can drive the throwing rod 100 to rotate clockwise around the first axis 101, so that the throwing rod 100 switches from the second position to the first position, which facilitates the ball serving mechanism 10 to perform continuous ball serving operations.

[0053] It should be noted that if directional indications (such as up, down, left, right, front, back, etc.) are involved in the embodiments of the present invention, these directional indications are only used to explain the relative positional relationships and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly. When a direction reference is introduced in a specific embodiment, unless the direction is specifically limited to unidirectional, the direction can be unidirectional or bidirectional (two parallel and opposite directions). Whether it is unidirectional or bidirectional depends on what those skilled in the art can achieve. When the direction reference is bidirectional, it should be considered that two parallel and different embodiments have been introduced simultaneously.

[0054] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or," "and / or," or "and / or" throughout the text implies three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.
