Description

Technical Field

[0001] This invention relates to a testing machine, and more particularly to a badminton testing machine for use in the field of badminton testing. Background Technology

[0002] With the improvement of people's living standards, more and more people have taken to badminton, leading to unprecedented development in the badminton industry. After long-term development, my country's badminton companies have become increasingly specialized, producing everything from shuttlecock feathers and shuttlecock heads to strings, with increasingly advanced technology and fiercer competition. Therefore, every company must improve its production technology to remain competitive in the market.

[0003] In my country's badminton manufacturing industry, badminton shuttlecocks need to undergo flight testing before leaving the factory. However, my country basically uses the manual hitting test method. Although this method is convenient, it is slow and the test quality is unstable.

[0004] To address the issues of slow testing efficiency and unstable testing quality, a certain badminton testing machine on the market adopts a mechanically driven automatic shuttlecock picking and striking design, and has a certain market share.

[0005] Chinese patent CN105091933B discloses a badminton shuttlecock detection machine, including a support frame. The top of the support frame has a support platform, and the top of the support platform has an O-ring. A shuttlecock storage container is fixed to the inner wall of the O-ring, and a frustum is located at the bottom of the storage container. A vertical plate is located in the middle of the support frame, and a wide support is located at the upper end of the vertical plate. A gripping device is fixed to the front end of the wide support. A short support is located at the lower end of the vertical plate, and a hydraulic cylinder is fixed to the front end of the short support. A horizontal plate is located below the vertical plate, and a hitting device is fixed to the upper end of the horizontal plate. This invention has advantages such as reasonable structural design and ease of use. It can automatically detect badminton shuttlecocks, replacing manual detection. It has a high degree of automation, improves the detection efficiency of badminton shuttlecocks, saves manpower and resources, and uses the hitting device to strike the shuttlecock, ensuring the flight speed of the shuttlecock and guaranteeing the detection quality.

[0006] The aforementioned badminton testing machine has multiple power sources to drive the movement of various components, enabling a series of testing actions such as picking up the shuttlecock, returning it to its original position, and hitting it. The coordination between these actions requires a certain gap, and the time for a single test is relatively long. In actual use, additional control equipment and control systems are needed to coordinate the driving of the multiple power sources in order to achieve the testing objective. The equipment cost is high, and the energy consumption of multiple power sources during testing is significant, which increases the testing cost accordingly. Summary of the Invention

[0007] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to shorten or eliminate the time interval between each action, ensure the smoothness of the action, improve the testing efficiency, and at the same time reduce the setting of power source, reduce equipment cost and testing cost while ensuring the testing effect.

[0008] To solve the above problems, the present invention provides a badminton testing machine, including a mounting plate and a mounting box. A shuttlecock discharge tube and a drive motor are respectively fixed at both ends of the mounting plate. A drive shaft that rotates through the mounting plate is fixed at the lower end of the output shaft of the drive motor. The lower end of the drive shaft rotates through the top wall of the mounting box. A fixing plate and a rotating shaft are fixed on the side of the mounting box away from the shuttlecock discharge tube.

[0009] A movable rod is fixed on the drive shaft, and a ball receiving frame is fixed at one end of the movable rod. The rotation path of the ball receiving frame is located below the ball outlet tube.

[0010] A racket is rotatably connected to one end of the fixed plate away from the mounting box. The racket is elastically connected to one side of the mounting box via a follow-up tension mechanism.

[0011] A transmission component is installed on the drive shaft to drive the follow-up tension mechanism to adjust the pitch. The transmission component rotates synchronously with the drive shaft.

[0012] A stop rod assembly is fixed at the end of the shaft away from the mounting box. The stop rod assembly consists of four stop rods arranged in a cross shape. The stop rod assembly is located between the movable rod and the hitting racket. When the stop rod assembly is kept vertical, the lower end of one of the stop rods presses against the hitting racket and keeps the hitting racket horizontal.

[0013] When the receiving frame moves to directly above the hitting racket, the lower end of the support rod separates from the hitting racket. At this time, the hitting racket rotates under the elastic force of the follow-up tension mechanism and hits the shuttlecock in the receiving frame.

[0014] The lower end of the shuttlecock outlet is equipped with a shuttlecock clamping plate for holding the shuttlecock. The lower end of the mounting plate is also equipped with a follow-up opening and closing mechanism that drives the shuttlecock clamping plate to deflect. When the shuttlecock receiving frame rotates to directly below the shuttlecock outlet, the movable rod drives the shuttlecock clamping plate to deflect and open through the follow-up opening and closing mechanism.

[0015] In the aforementioned badminton testing machine, the abutment group is initially kept vertical. One of the abutments presses against the racket at its lower end, keeping the racket horizontal. At this time, the movable rod deviates from the racket, and the receiving frame also deviates from the racket. When the drive motor drives the drive shaft to rotate, it drives the movable rod to rotate along the drive shaft. The movable rod drives the receiving frame to move directly below the ball outlet tube. At this time, the movable rod drives the ball clamping plate to deflect and open through the follower opening and closing mechanism, allowing the badminton shuttlecock to fall into the receiving frame. When the movable rod leaves, the follower opening and closing mechanism drives the ball clamping plate to deflect and close the ball outlet tube, so that the next badminton shuttlecock is clamped and positioned. The movable rod continues to move forward, driving the receiving frame to rotate and approach the abutment group, and drives the upper abutment to rotate. The lower abutment rotates and leaves the racket. After losing resistance, the racket rotates upward under the pulling force of the follower pulling mechanism and hits the badminton shuttlecock in the receiving frame, thus completing the badminton shuttlecock flight test.

[0016] During testing, the machine utilizes a follow-up tension mechanism and a follow-up opening and closing mechanism to complete a series of test actions—receiving, rotating, hitting, and receiving the shuttlecock—using a single power output source. The actions are fluid and unified. Compared to combining multiple actions to complete the test, the single test time is shorter, the testing efficiency is higher, and it does not require multiple power sources, saving power consumption. Furthermore, it does not require an additional control system; the test process can be adjusted simply by controlling the single rotation angle and speed of the drive motor. Compared to existing badminton testing machines, this testing machine has lower equipment costs and consumes less energy during testing, making it a promising candidate for widespread adoption.

[0017] As a further supplement to this application, the follow-up tension mechanism includes:

[0018] The slide rail is fixed to the side wall of the mounting box.

[0019] The slider is slidably connected to the slide rail.

[0020] The striking spring has one end fixed to the lower end of the slider, and the other end is located on the side of the abutment assembly near the mounting box and fixed to the middle of the racket.

[0021] The slider is driven by the transmission component to rise along the slide rail.

[0022] As a further supplement to this application, the transmission assembly includes:

[0023] A sector gear, which is fixedly sleeved on the drive shaft;

[0024] Driven gear, which meshes with sector gear;

[0025] The drive shaft is fixedly passed through the driven gear and rotatably connected to the top wall inside the mounting box.

[0026] A winding reel is fixed to the lower end of the drive shaft and is coaxially arranged with the drive shaft.

[0027] A connecting rope is wound on the reel, and the other end of the connecting rope passes through one side of the mounting box and is fixed to the upper end of the slider.

[0028] As a further supplement to this application, the tooth block distribution angle of the sector gear is greater than 90° and less than 180°;

[0029] The diameter of the winding reel is larger than the diameter of the driven gear, and they are in a multiple relationship.

[0030] As a further supplement to this application, the follow-up opening and closing mechanism includes:

[0031] The connecting rod is fixedly connected to one side of the ball-holding plate via a connecting plate.

[0032] Rotate the lever; the rotating lever is fixed to the end of the connecting rod away from the ball-locking plate.

[0033] A fixed shaft is provided, with one end of the fixed shaft fixed to the lower end of the mounting plate via a connector, and the other end of the fixed shaft rotatably connected to the side of the rotating block away from the connecting rod.

[0034] When the movable rod rotates and the ball receiving frame moves to directly below the ball outlet tube, the upper surface of the movable rod abuts against the bottom surface of the rotating block, making the rotating block horizontal. At the same time, the connecting rod rotates along the axis of the fixed shaft, causing the ball clamping plate to deflect and open.

[0035] As a further supplement to this application, the upper surface of the rotating block at the end away from the connecting rod is elastically connected to the bottom surface of the mounting plate via a return spring.

[0036] As a further supplement to this application, the rotating block has an inclined "L" shaped structure, and the angle formed between the two parts of the rotating block is an obtuse angle.

[0037] As a further supplement to this application, the connector includes a vertically arranged fixing plate two, the upper end of the fixing plate two is fixed to the lower end of the mounting plate, one end of the fixing shaft is fixed to one side of the fixing plate two, and the horizontal height of the lower end of the fixing plate two is higher than the horizontal height of the upper end of the movable rod.

[0038] As a further supplement to this application, one end of the ball-holding plate is provided with a "U"-shaped opening that mates with the ball-ejecting tube, and the inner diameter of the opening is smaller than the inner diameter of the ball-ejecting tube.

[0039] In summary, the first step involves keeping the abutment assembly vertical, with one abutment's lower end pressed against the racket, keeping it horizontal. At this point, as the movable rod deviates from the racket, the receiving frame also deviates. When the drive motor rotates the drive shaft, it causes the movable rod to rotate along the drive shaft. When the movable rod rotates until the receiving frame is close to directly below the outlet tube, one side of the movable rod contacts the bottom surface of the rotating block, gradually pushing the rotating block to make it horizontal. At this time, the connecting rod rotates along the axis of the fixed shaft, causing the clamping plate to gradually deflect and open. It fully opens when the receiving frame is directly below the outlet tube, allowing the shuttlecock to fall into the receiving frame, completing the shuttlecock retrieval action. After the receiving frame continues to rotate away from directly below the outlet tube with the movable rod, the rotating block rotates and resets under the action of the return spring, allowing the clamping plate to return to its original position. The racket returns to its original position, locking the next shuttlecock to prevent it from falling. The movable rod continues forward, driving the receiving frame to rotate and move closer to the abutment assembly. When the sector gear rotates to a certain angle, it meshes with the driven gear. The driven gear further drives the winding wheel to rotate through the transmission shaft, causing the connecting rope to wind onto the winding wheel. The contraction of the connecting rope causes the slider to move upward along the slide rail, stretching the hitting spring and accumulating a large tension. Then, the movable rod contacts the upper abutment of the abutment assembly, causing it to rotate. The lower abutment rotates away from the racket. After losing resistance, the racket rotates along its rotational connection with the fixed plate under the tension of the hitting spring. Finally, the racket rotates to a certain angle and hits the shuttlecock placed in the receiving frame, causing the shuttlecock to fly, thus completing the shuttlecock flight test.

[0040] During testing, the machine utilizes a follow-up tension mechanism and a follow-up opening and closing mechanism to complete a series of test actions—receiving, rotating, hitting, and receiving the shuttlecock—using a single power output source. The actions are fluid and unified. Compared to combining multiple actions to complete the test, the single test time is shorter, the testing efficiency is higher, and it does not require multiple power sources, saving power consumption. Furthermore, it does not require an additional control system; the test process can be adjusted simply by controlling the single rotation angle and speed of the drive motor. Compared to existing badminton testing machines, this testing machine has lower equipment costs and consumes less energy during testing, making it a promising candidate for widespread adoption.

Detailed Implementation

[0051] The following describes one embodiment of this application in detail with reference to the accompanying drawings.

[0052] Implementation method 1:

[0053] This invention provides a badminton shuttlecock testing machine; please refer to [link / reference]. Figures 1-3 The installation includes a mounting plate 1 and a mounting box 2. The ball outlet tube 5 and the drive motor 6 are fixed at both ends of the mounting plate 1, respectively. The lower end of the output shaft of the drive motor 6 is fixed with a drive shaft 10 that rotates through the mounting plate 1. The lower end of the drive shaft 10 rotates through the top wall of the mounting box 2. The mounting box 2 is fixed with a fixing plate 17 and a rotating shaft on the side away from the ball outlet tube 5.

[0054] A movable rod 3 is fixed on the drive shaft 10, and a ball receiving frame 19 is fixed at one end of the movable rod 3. The rotation path of the ball receiving frame 19 is located below the ball outlet tube 5.

[0055] The end of the fixed plate 17 away from the mounting box 2 is rotatably connected to the racket 4. The racket 4 is elastically connected to one side of the mounting box 2 through the follow-up tension mechanism 8.

[0056] A transmission component is installed on the drive shaft 10 to drive the follow-up tension mechanism 8 to adjust the pitch. The transmission component operates synchronously with the drive shaft 10.

[0057] A stop rod assembly 7 is fixed at the end of the rotating shaft away from the mounting box 2. The stop rod assembly 7 consists of four stop rods arranged in a cross shape. The stop rod assembly 7 is located between the movable rod 3 and the hitting racket 4. When the stop rod assembly 7 is kept vertical, the lower end of one of the stop rods presses against the hitting racket 4 and keeps the hitting racket 4 horizontal.

[0058] When the receiving frame 19 moves to directly above the hitting racket 4, the lower end of the abutment assembly 7 separates from the hitting racket 4. At this time, the hitting racket 4 rotates under the elastic force of the follow-up tension mechanism 8 and hits the shuttlecock in the receiving frame 19.

[0059] The lower end of the shuttlecock outlet tube 5 is equipped with a shuttlecock clamping plate 21 for clamping the shuttlecock. The lower end of the mounting plate 1 is also equipped with a follow-up opening and closing mechanism 9 that drives the shuttlecock clamping plate 21 to deflect. When the shuttlecock receiving frame 19 rotates to directly below the shuttlecock outlet tube 5, the movable rod 3 drives the shuttlecock clamping plate 21 to deflect and open through the follow-up opening and closing mechanism 9.

[0060] Based on the above structure, the abutment assembly 7 is initially kept vertical, with the lower end of one abutment pressing against the striking racket 4 and keeping the striking racket 4 horizontal. At this time, the movable rod 3 deviates from the striking racket 4, and the receiving frame 19 also deviates from the striking racket 4. (See reference here.) Figure 7 When the drive motor 6 drives the drive shaft 10 to rotate, it drives the movable rod 3 to rotate along the drive shaft 10. The movable rod 3 drives the receiving frame 19 to move directly below the shuttlecock outlet tube 5. At this time, the movable rod 3 drives the shuttlecock clamping plate 21 to deflect and open through the follow-up opening and closing mechanism 9, so that the shuttlecock falls into the receiving frame 19. (See reference here.) Figure 8 When the movable rod 3 moves away, the follower opening and closing mechanism 9 again drives the shuttlecock clamping plate 21 to deflect and close the shuttlecock outlet tube 5, thus locking and positioning the next shuttlecock. The movable rod 3 continues to move forward, driving the receiving frame 19 to rotate and move closer to the abutment assembly 7, causing the upper abutment to rotate. The lower abutment then rotates away from the hitting racket 4. After losing resistance, the hitting racket 4 rotates upward under the pulling force of the follower pulling mechanism 8 and strikes the shuttlecock in the receiving frame 19. (See reference here.) Figure 6 This completes the flight test of the badminton shuttlecock;

[0061] During testing, the machine utilizes two components—the follow-up tension mechanism 8 and the follow-up opening and closing mechanism 9—to complete a series of test actions—receiving, rotating, hitting, and receiving the shuttlecock—using the same power output source. The actions are fluid and unified. Compared to combining multiple actions to complete the test, the single test time is shorter, the test efficiency is higher, and it does not require multiple power sources to output power, saving energy consumption. At the same time, no additional control system is needed; the test process can be adjusted simply by controlling the single rotation angle and rotation speed of the drive motor 6. Compared to existing badminton testing machines, this testing machine has lower equipment costs and consumes less energy during testing, making it a promising candidate for widespread adoption.

[0062] Figure 2 The following is shown: The follow-up tension mechanism 8 includes:

[0063] Slide rail 15 is fixed to the side wall of the mounting box 2.

[0064] Slider 16 is slidably connected to slide rail 15;

[0065] The ball-hitting spring 18 has one end fixed to the lower end of the slider 16, and the other end of the ball-hitting spring 18 is located on the side of the abutment assembly 7 near the mounting box 2 and fixed to the middle of the racket 4.

[0066] The slider 16 is driven by the transmission assembly to rise along the slide rail 15.

[0067] When the upper stop rod of the stop rod assembly 7 rotates, causing the lower stop rod to rotate and leave the hitting racket 4, the hitting racket 4 rotates along the rotational connection between it and the fixed plate 17 under the tension of the hitting spring 18. Finally, the hitting racket 4 rotates a certain angle and hits the shuttlecock placed in the receiving frame 19, causing the shuttlecock to fly and completing the flight test.

[0068] Figure 2 The transmission assembly shown includes:

[0069] A sector gear 11 is fixedly sleeved on the drive shaft 10;

[0070] Driven gear 12 meshes with sector gear 11;

[0071] Drive shaft 13 is fixedly passed through driven gear 12 and rotatably connected to the inner top wall of mounting box 2;

[0072] The winding reel 14 is fixed to the lower end of the drive shaft 13 and is coaxially arranged with the drive shaft 13.

[0073] A connecting rope is wound on the reel 14, and the other end of the connecting rope passes through one side of the mounting box 2 and is fixed to the upper end of the slider 16.

[0074] When the drive shaft 10 rotates, it synchronously drives the sector gear 11 to rotate. When the sector gear 11 rotates to a certain angle, it meshes with the driven gear 12. At this time, the movable rod 3 drives the receiving frame 19 to rotate and move closer to the abutment group 7. The driven gear 12 further drives the winding wheel 14 to rotate through the transmission shaft 13, so that the connecting rope is wound on the winding wheel 14. The contraction of the connecting rope causes the slider 16 to move up along the slide rail 15, stretching the hitting spring 18 and accumulating a large tension. This allows the hitting spring 18 to pull the hitting racket 4 to rotate quickly and hit the shuttlecock after the abutment of the lower part of the abutment group 7 leaves the hitting racket 4 (at this time, the sector gear 11 is still meshed with the driven gear 12), thus completing the shuttlecock flight test.

[0075] Figure 4 The tooth block distribution angle of the sector gear 11 is greater than 90° and less than 180°; the diameter of the winding reel 14 is greater than the diameter of the driven gear 12 and is in a multiple relationship.

[0076] Figure 3 and Figure 5 The follower opening and closing mechanism 9 shown includes:

[0077] Link 22 is fixedly connected to one side of ball-locking plate 21 via a connecting plate;

[0078] Rotate the lever 23, and fix the end of the lever 23 and the connecting rod away from the ball-locking plate 21;

[0079] Fixed shaft 25, one end of fixed shaft 25 is fixed to the lower end of mounting plate 1 through a connector, and the other end of fixed shaft 25 is rotatably connected to the side of rotating block 23 away from connecting rod 22;

[0080] When the movable rod 3 rotates, the ball receiving frame 19 moves to directly below the ball outlet tube 5. The upper surface of the movable rod 3 abuts against the bottom surface of the rotating block 23, making the rotating block 23 horizontal. At the same time, the connecting rod 22 rotates along the axis of the fixed shaft 25, causing the ball clamping plate 21 to deflect and open.

[0081] When the movable rod 3 rotates to the point where the receiving frame 19 is close to the bottom of the dispensing tube 5, one side of the movable rod 3 abuts against the bottom surface of the rotating block 23 and gradually pushes the rotating block 23 to make it horizontal. At this time, the connecting rod 22 rotates along the axis of the fixed shaft 25, causing the shuttlecock clamping plate 21 to gradually deflect and open. When the receiving frame 19 is located directly below the dispensing tube 5, it is fully opened, allowing the shuttlecock to fall into the receiving frame 19 and completing the shuttlecock retrieval action.

[0082] Figure 3 The upper surface of the rotating block 23 away from the connecting rod 22 is elastically connected to the bottom surface of the mounting plate 1 via a return spring 24; the rotating block 23 has an inclined "L" shaped structure, and the angle formed between the two parts of the rotating block 23 is an obtuse angle.

[0083] After the receiving frame 19 continues to rotate away from directly below the shuttlecock outlet 5 with the moving rod 3, the rotating block 23 rotates and resets under the action of the reset spring 24, so that the shuttlecock clamping plate 21 resets again, locking and limiting the next shuttlecock level to prevent the shuttlecock from falling off.

[0084] Figure 3 and Figure 5 The connecting component includes a vertically arranged fixing plate 26. The upper end of the fixing plate 26 is fixed to the lower end of the mounting plate 1, and one end of the fixing shaft 25 is fixed to one side of the fixing plate 26. The horizontal height of the lower end of the fixing plate 26 is higher than the horizontal height of the upper end of the movable rod 3.

[0085] Figure 5 The shuttlecock clamping plate 21 has a "U"-shaped opening at one end that cooperates with the shuttlecock outlet tube 5. The inner diameter of the opening is smaller than the inner diameter of the shuttlecock outlet tube 5, which facilitates the positioning of the shuttlecock at the lower end of the shuttlecock outlet tube 5.

[0086] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
