Description

Technical Field

[0001] The utility model relates to the technical field of sports training equipment, and more specifically to a badminton racket for swing training. Background Art

[0002] Badminton is a popular sport and an international competitive sport. Badminton rackets are essential sports equipment for badminton. Existing badminton rackets are very good in terms of strength, durability, and appearance. However, as a sports training tool, existing badminton rackets cannot meet the requirements of sports training.

[0003] Badminton racket swing training involves the following: training the racket's sweet spot; training the racket's swing speed; and training the racket's explosive power. The badminton racket's sweet spot is the optimal striking area on the racket face, roughly elliptical in shape, with the racket's length as the vertical axis and its width as the horizontal axis. It's generally located slightly above the center of the racket, occupying approximately one-third to one-half of the racket's length vertically and about one-third of its width horizontally. Hitting the ball in the sweet spot provides sufficient power, minimizes racket vibration, and provides more stable ball control. Swing speed training focuses on increasing the overall racket's back and forth speed, allowing for more accurate swings against fast incoming balls. Training the explosive power of the swing strengthens overall explosive power and conceals movements, increasing the speed and threat of the ball.

[0004] Therefore, racket swing practice is extremely important in badminton training. Currently, existing training methods mainly rely on coaching guidance and high-speed camera playback, which are highly specialized. For ordinary enthusiasts who want to improve their skills, the investment cost is high and it is not convenient. Therefore, this application proposes a badminton racket that facilitates independent training for enthusiasts. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a badminton racket for swing training, which can effectively measure the vibration of the badminton racket when hitting the ball, the swing speed and the degree of deformation of the middle shaft during the swing. Through the above data, it can provide feedback to the trainer on whether the sweet spot is hit, the speed of the swing and the size of the explosive force, thereby making it easier for the trainer to understand his own situation and improve his technical movements in a timely manner.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solution: a badminton racket for swing training, comprising a handle, a middle shaft and a racket frame, the racket frame being provided with a ball hitting detection device, the middle shaft being provided with a swing speed detection device and a middle shaft deformation detection device, the handle being provided with a control device, and the ball hitting detection device, the swing speed detection device and the middle shaft deformation detection device all transmitting detected data information to the control device.

[0007] The utility model is further configured as follows: the control device includes a fixed compartment embedded in the bottom of the handle, and a single-chip microcomputer module, a battery module and a Bluetooth module are installed in the fixed compartment. The battery module is used to power the single-chip microcomputer module and the Bluetooth module. The single-chip microcomputer module is used to receive transmitted data information, and the Bluetooth module is used to transmit data information to an external terminal.

[0008] The present invention is further configured as follows: the ball hitting detection device, the swing speed detection device and the middle shaft deformation detection device are all electrically connected to the single chip computer module through wires.

[0009] The utility model is further configured as follows: the ball hitting detection device includes a plurality of vibration sensors, and the plurality of vibration sensors are fixedly arranged on the border of the racket frame.

[0010] The utility model is further configured as follows: two vibration sensors are provided, one of which is provided on the lower frame of the racket frame close to the middle rod, and the other is provided on the left frame or the right frame of the racket frame.

[0011] The utility model is further configured as follows: the swing speed detection device includes an acceleration sensor, and the acceleration sensor is fixedly arranged at one end where the middle shaft is connected to the racket frame.

[0012] The present invention is further configured as follows: the center rod deformation detection device includes a strain gauge sensor, and the strain gauge sensor is attached to the middle section of the center rod.

[0013] The utility model is further configured as follows: a shock-absorbing sponge is provided between the fixed compartment and the handle.

[0014] In summary, the present invention has the following beneficial effects:

[0015] Compared to the existing technology, the present invention provides a swing speed detection device and a shaft deformation detection device on the shaft of a badminton racket. The acceleration sensor of the swing speed detection device is located near the connection between the shaft and the racket frame, which can more closely detect the actual swing speed and effectively provide feedback on the trainee's swing speed. The shaft deformation detection device can detect the degree of bending deformation of the shaft. When the swing force is strong, the shaft deformation is greater, thus effectively providing feedback on the trainee's explosive power. The ball hitting detection device can detect the vibration of the racket frame. When the vibration is small, uniform and stable, it indicates that the ball is hit in the sweet spot, effectively providing feedback on the trainee's sweet spot hit rate. At the same time, the above data is fed back to the control device and sent via Bluetooth to an external terminal such as a mobile phone, helping the trainee understand their own swing movements, etc., without the need for professional equipment, and is particularly suitable for trainees' independent training.

DETAILED DESCRIPTION

[0020] The present invention will be described in further detail below with reference to the accompanying drawings.

[0021] This embodiment discloses a badminton racket for swing training, such as Figure 1-3 As shown, the racket comprises a handle 1, a shaft 2, and a frame 3. The frame 3 is provided with a ball striking detection device 31, the shaft 2 is provided with a swing speed detection device 21 and a shaft deformation detection device 22, and the handle 1 is provided with a control device 4. The ball striking detection device 31, the swing speed detection device 21, and the shaft deformation detection device 22 all transmit detected data to the control device 4. Through the above arrangement, the ball striking detection device 31 detects the trainee's hitting position data, the swing speed detection device 21 detects the trainee's swing speed data, and the shaft deformation detection device 22 detects the degree of shaft deformation during the swing. These data can provide comprehensive feedback on the trainee's swing information, helping the trainee understand their own swing speed, explosive power, and hitting point.

[0022] Furthermore, the control device 4 includes a fixed compartment 8 embedded in the bottom of the handle 1. The fixed compartment houses a single-chip microcomputer module, a battery module, and a Bluetooth module. The battery module is used to power the single-chip microcomputer module and the Bluetooth module. The battery module integrates a lithium battery and a charging module to achieve charging and battery life. The single-chip microcomputer module is used to receive transmitted data information, and the Bluetooth module is used to transmit data information to an external terminal. Through the above configuration, the external terminal is preferably a mobile phone, and the Bluetooth module is connected to the mobile phone. The connection between the mobile phone and Bluetooth and data collection are existing technologies. The mobile phone records and displays the data information for intuitive viewing by the trainer.

[0023] Furthermore, the ball hitting detection device 31, the swing speed detection device 21 and the middle rod deformation detection device 22 are all electrically connected to the single chip microcomputer module through the wire 6. Figure 2The wire 6 preferably extends along the edge of the racket frame 3 and the path of the middle shaft 2, so that when the racket is swung, the wire 6 has little interference with the wind resistance. At the same time, the wire can be fixed with tape 7 or other means to ensure that the wire 6 does not shake during the swing.

[0024] Furthermore, the ball striking detection device 31 includes a plurality of vibration sensors 311. These vibration sensors 311 are fixedly mounted on the frame 3. In this embodiment, two vibration sensors 311 are provided: one located on the lower frame 3 near the middle shaft 2, and the other located on the left or right frame 3. The left or right frame here refers to the relative orientation of the racket frame 3 when the net is facing the user. With this arrangement, the two vibration sensors 311 are placed in different locations, enabling more efficient detection of vibration data, which is then fed back to the trainer's mobile phone via the control device. Suppose a trainer practices swinging the racket ten times. The trainer sees on their mobile phone that the vibration data is small for eight of the ten times, and the data from the two vibration sensors are comparable. This indicates that eight out of ten shots were made in the sweet spot, resulting in an 80% sweet spot strike rate. This allows the trainer to intuitively assess the stability of their sweet spot strikes. If the probability is too low, they should prioritize training their striking motion and feel. In addition, more vibration sensors can be set up according to actual needs to ensure the accuracy of detection through more data comparison. It can even be combined with machine learning and data statistics to obtain the accurate landing point of the ball through vibration data, thereby further improving the training effect.

[0025] Furthermore, the swing speed detection device 21 includes an accelerometer 211, which is fixedly mounted at the end where the middle shaft 2 connects to the racket frame 3. Since the farther the end of the racket is from the racket frame, the faster it is during a swing, placing it closer to the racket frame 3 allows for relatively accurate swing speed detection. The accelerometer 211 detects acceleration, calculates the swing speed within the swing time using a single-chip microcomputer, and transmits the information to a mobile phone. This allows the trainee to determine their own swing speed, providing data support for subsequent swing speed training and helping the trainee understand changes in their own swing speed.

[0026] Furthermore, the center rod deformation detection device 22 includes a strain gauge sensor 221, which is attached to the middle section of the center rod 2. The deformation generated in the middle section of the center rod 2 is greater than at the ends, so it is located in the middle section. In this embodiment, three strain gauge sensors are preferably provided, spaced apart on the center rod 2. The strain gauge sensors 221 are conventional technology. When deformed by external forces, their resistance changes accordingly, thereby converting the deformation of the center rod into an electrical signal. The greater the deformation during a swing, the greater the instantaneous explosive force of the swing. Trainers can monitor their own explosive force through their mobile phones, train for instantaneous explosive force during swings, and improve the concealment of movements.

[0027] Further, in order to ensure the stability of the fixed warehouse 8, refer to Figure 2 A shock-absorbing sponge 5 is provided between the fixed compartment 8 and the handle 1. The flexible shock-absorbing sponge 5 reduces the shaking impact on the fixed compartment 8 when swinging the racket. In addition, the fixed compartment 8 is detachable. A socket is provided on the top to cooperate with the wire 6, and a screw cover 9 is provided on the bottom to cooperate with the thread of the handle 1. The fixed compartment can be taken out by unscrewing the screw cover 9. After taking it out, it can be charged for convenient use.

[0028] It should be noted that Figure 3 In the block diagram, the arrows on the connection lines between devices and modules only indicate the direction of data transmission after the swing and the power supply of the battery to the microcontroller, and do not mean that data connection between devices and modules can only be carried out in the direction of the arrow. For example, the microcontroller module also supplies power to the ball hitting detection device, the swing speed detection device and the middle shaft deformation detection device, and the external terminal can also transmit signals to the microcontroller module through the Bluetooth module.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention should be included in the scope of protection of the present invention.
