Background Technology

[0002] As a key piece of equipment in badminton, the performance of a badminton racket directly affects an athlete's performance. The racket's elasticity and swing are crucial for power transfer and control precision in shots. With the increasing popularity of badminton and the improvement of competitive levels, more and more badminton racket industry professionals and athletes have a greater need for in-depth understanding of the racket's physical properties and have raised related requirements regarding racket swing and shock absorption performance.

[0003] However, current market research on the physical properties of badminton rackets mainly focuses on weight, balance, and overall stiffness. There is no clear research method for assessing racket swing and shock absorption performance; research often relies on manual observation and experience, lacking objective and precise quantitative indicators. Therefore, developing a device that can accurately test the elasticity and swing of badminton rackets is particularly important. Utility Model Content

It is used to check and correct the initial orientation.

[0011] Furthermore, the test platform is provided with a groove buckle, and the handle is installed on the groove buckle by means of pressing, nesting, and locking, thereby fixing the badminton racket on the test platform.

[0012] Furthermore, the racket deformation component uses physical traction to bend the racket head.

[0014] Furthermore, the signal transmitting component is fixed to the top of the racket head using a clamp or buckle to ensure that the signal transmitting component will not loosen due to the swinging of the badminton racket.

[0015] Furthermore, the second signal receiver has several signal receivers spaced at equal intervals in the vertical and horizontal directions to form a signal receiver matrix, thereby expanding the signal reception range.

[0028] The test platform 2 of this utility model is used to place and fix the handle of the badminton racket 5, and the test platform 2 is in an absolutely horizontal position to ensure that the badminton racket 5 is tested in a horizontal state.

[0029] In a preferred embodiment of this invention, the test platform 2 is provided with a recessed buckle 8, and the handle is installed on the recessed buckle 8 by means of pressing, nesting, locking, etc., thereby fixing the badminton racket 5 on the test platform 2. Of course, in addition to providing a recessed buckle 8, common methods such as protrusions or direct locking can also be used to fix the racket on the test platform, as long as it can achieve the goal of fixing the racket on the test platform.

[0030] The racket deformation component 3 of this utility model is located below the head of the badminton racket 5 and is used to bend the racket head to simulate the deformation state at the moment of hitting the ball.

[0031] In a preferred embodiment of this invention, the racket deformation component 3 uses physical traction methods such as electromagnet attraction, string pulling, or manual swinging to bend the racket head. Of course, any other method that can deform the racket and simulate the moment of impact is also applicable to this invention.

[0032] The signal transmitting component 1 of this utility model is located at the intersection of the top of the racket head and the central axis of the racket, and the signal transmitting component 1 includes a first signal transmitter 6 and a second signal transmitter 7. The first signal transmitter 6 is used to transmit signals in the direction of extending the racket head, and the second signal transmitter 7 is used to transmit signals in the direction of the handle.

[0033] In a preferred embodiment of this invention, the signal transmitting component 1 is fixed to the top of the racket head using a clamp, a buckle, or other common fixing method to ensure that the signal transmitting component 1 will not loosen due to the swinging of the badminton racket 5.

[0034] The signal receiving component of this utility model includes a first signal receiver 41 and a second signal receiver 42. The first signal receiver 41 is located behind the handle and on the top-view central axis of the badminton racket 5, and is at the same horizontal height as the signal emitted by the second signal transmitter 7. It is used to check whether the center position of the racket head is on the central axis of the badminton racket, thereby checking whether the badminton racket is tilted. The second signal receiver 42 is located in front of the racket head and is in the horizontal direction of the racket head, intersecting the top-view central axis of the badminton racket 5, in order to check and correct the initial orientation.

[0035] In a preferred embodiment of this utility model, the second signal receiver 42 is provided with a plurality of signal receivers at equal intervals in the vertical and horizontal directions to form a signal receiver matrix, thereby expanding the signal reception range.

[0036] As a further preferred embodiment of this utility model, the signal transmitting component is a laser transmitting component, and the first signal transmitter and the second signal transmitter are a first laser transmitter and a second laser transmitter; the signal receiving component is a laser receiving component, and the first signal receiver and the second signal receiver are a first laser receiver and a second laser receiver; the signal receiver matrix is ​​a laser receiver matrix.

[0037] In addition, the signal transmitting component of this utility model can also be in other forms such as radio, and the signal receiving component can be in the form of a signal receiving board, laser receiving matrix, etc., as long as the purpose of transmitting and receiving signals of this utility model can be achieved.

[0038] How this utility model is used:

[0039] The test platform is precisely calibrated to ensure its levelness meets the testing requirements. The badminton racket is fixed to the grooved clip on the test platform, and the signal transmitting component (using a laser transmitter as an example) is fixed at the intersection of the top of the racket head and the racket's central axis. The second laser transmitter emits a laser beam towards the handle (dashed line 9 in the diagram). If the badminton racket is not tilted, the first laser receiver should receive the signal and provide feedback; at this point, it should be recorded that the badminton racket is not tilted. If this step passes the test, the first laser transmitter emits a laser beam towards the racket head (dashed line 10 in the diagram), and the second laser receiver should receive the signal and record it. At this point, the badminton racket has not yet deformed; this laser receiver record is the starting point.

[0040] At this time, the racket deformation component is used to pull the badminton racket, causing it to deform to simulate the bending at the moment of impact. At the same time, the laser emitted by the first laser emitter is received by a laser receiver in the laser receiver matrix, which is the deformation value at the moment of impact.

[0041] When the badminton racket is in a stable and static state under the traction of the racket deformation component, the traction is released, the racket rebounds and begins to swing. At this time, the laser emitted by the first laser emitter is received by multiple laser receivers in the laser receiver matrix. The lasers are received and recorded continuously at time nodes in chronological order. As the racket swings and rebounds gradually decrease and enters a static state, the test ends.

[0042] By analyzing the positions of the laser receivers in the laser receiver matrix and the order in which they received the laser light, we can obtain the following information:

[0043] ① The maximum value and duration of the first racket rebound, which represents the racket's deformation state and time during rebound;

[0044] ② The time it takes for the racket to bounce back and come to a standstill indicates the racket's shock absorption performance;

[0045] ③ The signals received by the laser receivers arranged to the left and right of the central axis are evidence of invalid racket swings. A high-quality badminton racket will have fewer invalid swings.

[0046] Therefore, this utility model provides a device for testing the elasticity and swing of a badminton racket. This device accurately evaluates the elasticity and swing performance of a badminton racket by simulating the deformation state at the moment of impact and using signal transmission and reception components. It has the advantages of accurate testing and simple operation, and provides strong technical support for the research and development and production of badminton rackets.

[0047] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
