Description

Technical Field

[0001] This utility model relates to a light-emitting racket swing practice device, and pertains to the field of sports equipment. Background Technology

[0002] Existing conventional racket practice devices lack light-emitting functionality, making it impossible to observe the swing motion and racket movement path in low-light environments such as at night, thus hindering the assessment of the accuracy of the swing. Furthermore, conventional racket practice devices frequently experience impacts to the racket frame due to the impact of training balls or their landings. If LEDs are directly installed within the racket frame, these impacts can easily lead to issues such as poor soldering, resulting in shortened LED lifespan or, in more serious cases, short circuits and combustion. Even worse, the LEDs may shatter, releasing small fragments that pose a risk of getting into the eyes, especially when the device is lifted. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the technical problem that existing luminous swing practice devices do not have a light-emitting function, and to provide a luminous swing practice device.

[0004] The technical solution adopted by this utility model to solve its technical problem is: A light-emitting swing practice device includes: a racket frame and a racket handle, the racket handle being fixedly connected to the racket frame, a light-transmitting part being provided on the racket frame, a light-guiding part being provided inside the racket frame, the position of the light-guiding part being adapted to the position of the light-transmitting part, the light from the light-guiding part being transmitted through the light-transmitting part toward the outside of the racket frame, and a light source being provided at the end of the light-guiding part, the light from the light source being diffusely reflected inside the light-guiding part.

[0005] As a further improvement of this utility model, the light source includes an LED bead, and a convex lens is provided at the front end of the LED bead, so that the light from the LED bead is focused onto the light guide section through the convex lens. By setting a convex lens at the front end of the LED bead to refract and converge the light, the light is made more concentrated and uniformly enters the light guide, reducing light energy loss and improving the clarity of the light path; at the same time, the linear light is diffusely reflected in the light guide, ensuring that the brightness of the light transmission part is consistent throughout, avoiding local over-brightness or under-brightness.

[0006] As a further improvement of this utility model, the light source includes a driving unit, which is fixed inside the racket handle; The drive unit includes a drive board, a positive contact is provided at the bottom of the drive board, a negative extension line is provided on the side of the drive board, a control switch is connected to the end of the negative extension line, a negative contact is provided at the front end of the control switch, and the control switch is used to control the conduction between the negative contact and the negative extension line. The LED beads are mounted on the driver board, and the LED beads are connected to the positive contact and the negative extension line through the driver circuit; The drive unit is integrated into the racket handle, which optimizes the racket's weight distribution and enhances the protective structure for the drive unit.

[0007] As a further improvement of this utility model, a cylindrical fixing groove is provided inside the racket handle, the drive unit is fixed in the fixing groove, a connecting ring coaxial with the fixing groove is fixed at the end of the racket handle, and a tail cap is connected to the end of the racket handle through the connecting ring. The outer wall of the control switch is provided with a limit ring, which contacts the end of the connecting ring. The end of the tail cover is provided with an operating hole for pressing the control switch. The control switch is installed at the end of the racket handle through the cooperation of the limiting ring and the connecting ring. The practitioner can easily press the control switch in the operation hole with one hand to turn the light source on or off without complicated operation. It is ergonomically designed and more convenient to use.

[0008] As a further improvement of this utility model, an end connecting block is embedded and fixed inside the racket handle. The end connecting block is coaxially arranged with the convex lens, and the end of the light guide part is fixed through and fixed to the middle of the end connecting block. The end connecting block provides stable support for the light guide, preventing it from shifting during the swing of the exerciser and affecting the light emission effect.

[0009] As a further improvement of this utility model, the racket frame includes an upper racket shell and a lower racket shell, and structural grooves are provided inside the upper racket shell and the lower racket shell; a plurality of support plates for supporting the light guide are arranged in an array inside the structural groove of the upper racket shell or the lower racket shell, and a plurality of support grooves for embedding the light guide are arranged in an array on the support plates. The racket uses a split shell assembly, which is easy to process and install. The structural groove can reduce the obstruction of the light guide by the support structure and improve the light illumination efficiency.

[0010] As a further improvement of this utility model, a plurality of connecting column structures are arranged in an array between the upper shell and the lower shell of the racket, and the two ends of the connecting column structures are fixedly connected to the upper shell and the lower shell of the racket; wherein, the connecting column structure includes plug-in columns and plug-in tubes that are plugged into each other and fixedly connected. The use of a plug-in structure for fixing makes the structure simpler.

[0011] As a further improvement of this utility model, the racket handle includes an upper handle shell integral with the upper shell of the racket and a lower handle shell integral with the lower shell of the racket.

[0012] As a further improvement of this utility model, the light guide part is a whole-body light-emitting optical fiber; The technology of all-emitting optical fibers is mature and inexpensive.

[0013] As a further improvement of this utility model, the light-transmitting part and the racket frame are an integral structure; the racket frame is a racket frame made of transparent material or light-transmitting material; the light-transmitting part is a light-transmitting part made of transparent material; The racket is entirely translucent, eliminating the need for additional translucent plastic sheets or other structures, thus reducing manufacturing costs and simplifying the structure.

[0014] The beneficial effects of this utility model are: This invention incorporates a light guide in existing rackets. The light guide is made of diffuse reflection light-guiding material and uses a light source located inside the racket handle to provide illumination. This not only improves the racket's visibility at night but also enhances the enjoyment of using it. Furthermore, the light source is placed in the impact-resistant handle, making it less susceptible to damage during use or accidental drops. In addition, the light guide reduces the weight of the racket frame, preventing a top-heavy situation, and even if the racket frame cracks, it will not pose a danger. Attached Figure Description
