Description

Racket Technical Field

[0001] The present application relates to the field of rackets, and in particular to a racket for ball sports. Background Art

[0002] Many ball sports, such as tennis, squash, badminton, racquet, and cricket, are played with a racket. Typically, a racket comprises a striking head and a handle. The striking head comprises a frame and a striking member (such as a plate, a string, or the like) disposed within the frame. If the striking member requires a solid structure of considerable thickness, it is often manufactured from materials such as plastic, wood, or metal, which increases manufacturing costs and makes the racket heavy, making it less suitable for striking.

[0003] Furthermore, during general training, athletes often rely on photography, observations by others, or their own feelings to determine relevant information such as the swing angle, force, or speed of their rackets. This makes it impossible to directly obtain relevant data, resulting in poor training efficiency and a shortcoming that urgently needs to be improved.

DETAILED DESCRIPTION

[0021] The following examples are merely illustrative of possible implementations of the present application, and are not intended to limit the scope of protection sought by the present application. The "one" or "at least one" preceding the nouns mentioned herein does not limit the quantity, and "several" may also be used as required. Such changes in quantity also fall within the scope of protection sought, and are therefore clearly stated.

[0022] Please refer to Figures 1 to 4, which show a preferred embodiment of the present application. The shooting tool 1 of the present application includes a frame 10, an elastic supporting structure 20, two shooting parts 30, a sensing unit 40 and a transmission unit 50.

[0023] The frame 10 includes a frame wall 11 and a handle 12 connected to each other, the frame wall 11 enclosing a receiving space 13; the elastic support structure 20 is arranged in the receiving space 13 and is fixed to the frame wall 11 with one side thereof, the elastic support structure 20 includes a plurality of channels 21 passing through the two sides of the elastic support structure 20 in the thickness direction; the two flap parts 30 are arranged on opposite sides of the elastic support structure 20 and are fixed to the frame wall 11, each of the flap parts 30 includes a plurality of through holes 31, and the plurality of through holes 31 at least partially correspond to and communicate with the plurality of channels 21; the sensing unit 40 is arranged on the frame 10, the At least one of the elastic support structure 20 and the two racket sections 30 includes at least one gravity sensor 41 (G-sensor) and at least one gyroscope 42. The at least one gravity sensor 41 can sense an acceleration of the racket 1 and generate acceleration data, and the at least one gyroscope 42 can sense an angular velocity of the racket 1 and generate angular velocity data. The transmission unit 50 is connected to the sensing unit 40 and can receive signals related to the acceleration data and the angular velocity data and output them to an external device. This can output relevant data when the user swings the racket as a training basis, effectively improving training efficiency.

[0024] In this embodiment, the at least one gravity sensor 41 and the at least one gyroscope 42 are disposed within the accommodating space 13 and between the two face-slapping surfaces 30. Each gravity sensor 41 and each gyroscope 42 are offset from the plurality of through-holes 31, thereby improving sensing accuracy and preventing accidental removal of the at least one gravity sensor 41 and the at least one gyroscope 42. In other embodiments, the at least one gravity sensor and / or the at least one gyroscope may also be disposed within the frame wall or the handle, depending on sensing requirements. The sensing unit may also include a vibration sensor that generates a sensing signal when the two face-slapping surfaces are slapped, thereby obtaining relevant data such as the location and force of the slapping.

[0025] Specifically, the elastic support structure 20 is provided with at least one receiving groove 22, each of which opens toward one of the flap sections 30. The at least one gravity sensor 41 and the at least one gyroscope 42 are immovably embedded within each of the receiving grooves 22, facilitating assembly and ensuring stability. Preferably, the at least one gravity sensor 41 and the at least one gyroscope 42 are provided in multiple numbers. At least one receiving groove 22, at least one gravity sensor 41, and at least one gyroscope 42 are provided on opposite sides of the elastic support structure 20, respectively, as shown in FIG3 , resulting in excellent sensing sensitivity and accuracy. However, the gravity sensors and gyroscopes may also be embedded within the elastic support structure.

[0026] With reference to Figure 1, each racket portion 30 defines a main striking area 32 extending along the frame wall 11 on a side relatively away from the handle 12. In a length direction of the racket 1, an extension length of each main striking area 32 is 2 / 3 of a maximum length of the racket portion 30. The sensing unit 40 is arranged between the main striking areas 32 of the two racket portions 30, thereby obtaining the acceleration data and the angular velocity data of the main striking area 32, and further calculating various relevant data such as the swing angle, path, and holding time of the racket.

[0027] The elastic support structure 20 is a foam filler or a three-dimensional grid, which has sufficient structural strength and is light weight, which helps to make the racket 1 lightweight and easy to operate and use; the average hardness of each racket portion 30 is greater than the average hardness of the elastic support structure 20, which can keep each racket portion 30 flat and have good resilience to provide a good hitting effect. In this embodiment, the elastic support structure 20 is a foam filler, such as, but not limited to, PU, ​​EVA, PE, or PVA. This material is lightweight and low-cost. The hardness and elasticity of the elastic support structure 20 can be adjusted by adjusting the foam density and material selection to meet different usage requirements. The number of channels 21 is equal to the number of through-holes 31 in each of the flap sections 30, effectively reducing air resistance. The through-holes 31 allow each flap section 30 to extend discontinuously, allowing for different contact states with the object being struck during each strike. The distance between the flap sections 30 is no less than 2 cm, providing excellent structural strength, shock absorption, and convenient placement of the various components of the sensing unit 40. However, the number of channels may also be greater than the number of through-holes in each flap section to facilitate lightweighting.

[0028] Preferably, the racket 1 further includes a processing unit 60 connected between the sensing unit 40 and the transmission unit 50. The processing unit 60 includes a timing module 61 and a storage module 62. The processing unit 60 can store the acceleration data and the angular velocity data in the storage module 62 in a time sequence based on a time information of the timing module 61. In this way, the user's operation actions and sequence can be fully stored and recorded, and then the data can be output to the external device in real time, aperiodically, or periodically via the transmission unit 50. The external device, such as but not limited to a mobile phone, a computer, a cloud server, a tablet computer, etc., can read the acceleration data and the angular velocity data for analysis, so as to correct and adjust the user's racket swing action accordingly.

[0029] The transmission unit 50 includes at least one of a Bluetooth transmission module 51, an ANT+ transmission module 52, an infrared transmission module, and a wireless radio frequency transmission module, which can be configured and selected as needed for ease of operation. The video recorder 1 also includes a power supply unit 70, such as but not limited to a storage battery or a disposable battery. The power supply unit 70 is electrically connected to the sensing unit 40, the processing unit 60, and the transmission unit 50 to supply power.
