Description

Technical Field

[0001] This invention relates to the field of badminton technology, specifically to an energy-saving light-emitting badminton shuttlecock and its charging device. Background Technology

[0002] Badminton, as a highly popular sport, traditionally uses shuttlecocks made of natural feathers or nylon plastic, which do not have light-emitting capabilities. To meet the needs of playing at night or in low-light environments, light-emitting shuttlecocks have emerged.

[0003] Currently, most light-up badminton shuttlecocks on the market integrate LED beads, button batteries or small rechargeable batteries, and control circuitry inside the shuttlecock head. Controlled by a switch, the LEDs are lit up by inertia when hit, creating a beautiful light trail that greatly enhances the fun and visibility of nighttime sports.

[0004] Existing luminous badminton shuttlecock products mostly use adhesive (such as glue fixation) or mechanical snap-fit ​​(such as buckle or threaded connection) connection methods, which have the following defects in long-term use: While badminton shuttlecocks rely on the adhesive strength of glue, the repeated hitting and high-speed movement subject them to severe vibrations and impacts, causing the glue layer to fatigue, age, or crack, leading to loosening or even detachment of the connection points. Furthermore, the glue's reliability can be further reduced by environmental temperature and humidity. While threaded connections are easy to disassemble, during a badminton match, the shuttlecock experiences uneven torque and centrifugal force due to changes in the hitting angle. This can cause slight relative rotation in the threaded parts, which can lead to stripping or loosening over time. Clamping mechanisms, on the other hand, are prone to wear or deformation under vibration, losing their locking function. Summary of the Invention

[0005] The purpose of this invention is to provide an energy-saving light-emitting badminton shuttlecock and its charging device. Through modular design and a rotating wireless charging device, it achieves convenient maintenance and efficient charging, aiming to solve the shortcomings of existing light-emitting badminton shuttlecocks in terms of maintenance and charging.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an energy-saving light-emitting badminton shuttlecock, comprising an elastic head, a rigid transparent skirt, a feather skirt, and a light-emitting module. The rigid transparent skirt has an insertion hole on its surface, and the feather skirt is inserted into the insertion hole. The elastic head includes a rigid transparent shell, an elastic buffer layer, and a mounting cavity. The elastic buffer layer is sleeved on the surface of the rigid transparent shell. The rigid transparent shell has a mounting cavity on its surface, and the light-emitting module is disposed within the mounting cavity. A threaded structure is provided on the outside of the mounting cavity, and the rigid transparent skirt is threadedly connected to the rigid transparent shell. The side of the light-emitting module away from the elastic ball head contacts the end surface of the rigid transparent ball skirt. The end of the rigid transparent ball skirt is provided with a flange structure, and the surface of the flange structure is symmetrically provided with limit grooves. The light-emitting module includes a housing, an end cap, an LED light-emitting component, a control circuit board, an energy storage module, an electromagnet unit, a limiting block, and a spring. The end cap is fixedly disposed at one end of the housing. The control circuit board and the energy storage module are both fixedly disposed inside the housing. The control circuit board integrates the LED light-emitting component and a vibration sensing switch. The LED light-emitting component is disposed on the side wall of the housing. A slide rail is disposed on the surface of the end cap. A boss is disposed inside the slide rail. The limiting block is slidably disposed inside the slide rail. The spring connects the boss and the limiting block. The electromagnet unit is disposed on the surface of the boss and can fit against the surface of the limiting block. The limiting block can enter the limiting groove.

[0007] As a further embodiment of the present invention, the bottom of the mounting cavity is provided with two sets of positioning holes, and the end of the outer shell away from the end cover is provided with two sets of positioning pins, and the two sets of slide rails correspond to the positions of the two sets of positioning pins respectively.

[0008] As a further embodiment of the present invention, a receiving coil is provided on the surface of the end cap at a position corresponding to the energy storage module.

[0009] As a further embodiment of the present invention, the end cap surface is symmetrically provided with slots, and the surface difference between the limiting block and the end cap is not less than the depth of the slots.

[0010] A charging device includes a bottom shell, a top cover, terminals, and wireless charging units. The top cover is rotatably connected to the bottom shell, and a plurality of wireless charging units are symmetrically distributed about the terminals. The end cap can overlap the surface of the wireless charging units.

[0011] As a further embodiment of the present invention, the wireless charging unit includes a rotating tube, a tray, and a wireless charging plate. The tray is fixedly connected to one end of the rotating tube, and the other end of the rotating tube is rotatably connected to the surface of the terminal block. The surface of the tray is provided with the wireless charging plate, and the end cap can contact the wireless charging plate.

[0012] As a further embodiment of the present invention, the tray surface is provided with a limiting protrusion, and both the limiting block and the slot can contact the surface of the limiting protrusion.

[0013] The beneficial effects of the present invention are as follows: (1) When the badminton shuttlecock of this application is hit or impacted, the vibration sensing switch is triggered, and the LED light-emitting component and the electromagnet unit are powered on. The electromagnet unit after being powered on generates magnetic force, which adheres to the surface of the limiting block, overcomes the elastic force of the spring, and drives the limiting block to slide along the slide rail and insert into the limiting groove at the end of the hard transparent shuttlecock skirt. This effectively prevents the relative rotation between the hard transparent shuttlecock skirt and the hard transparent shell caused by the hitting angle, which not only ensures the reliability in use, but also reduces the maintenance cost.

[0014] (2) When the badminton shuttlecock is not in the hitting state, the vibration sensing switch is turned off, the electromagnet unit is de-energized, and the spring force drives the limit block to automatically exit the limit groove and return to the free state. The user can directly rotate the hard transparent shuttlecock skirt to disassemble the light-emitting module for maintenance or replacement.

[0015] (3) The engagement of the limiting protrusion and the slot in the charging device of this application prevents the shuttlecock from shifting or rotating during the charging process, ensuring the stability of the charging contact, avoiding charging interruption caused by vibration, and improving charging efficiency. At the same time, the wireless charging unit is rotatable, adapting to different placement methods, improving user experience and portability. Attached Figure Description

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0029] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0030] Please see Figures 1 to 8 In one embodiment of the present invention, an energy-saving light-emitting badminton shuttlecock includes an elastic head 110, a rigid transparent skirt 120, a feather skirt 130, and a light-emitting module 140. The rigid transparent skirt 120 has an insertion hole 123 on its surface, and the feather skirt 130 is inserted into the insertion hole 123. The elastic head 110 includes a rigid transparent shell 111, an elastic buffer layer 112, and a mounting cavity 114. The elastic buffer layer 112 is sleeved on the surface of the rigid transparent shell 111. The rigid transparent shell 111 has a mounting cavity 114 on its surface, and the light-emitting module 140 is disposed in the mounting cavity 114. A threaded structure 113 is provided on the outside of the mounting cavity 114, and the rigid transparent skirt 120 is threadedly connected to the rigid transparent shell 111. The side of the light-emitting module 140 away from the elastic ball head 110 is in contact with the end surface of the rigid transparent ball skirt 120. The end of the rigid transparent ball skirt 120 is provided with a flange structure 121, and the surface of the flange structure 121 is symmetrically provided with limit grooves 122. The light-emitting module 140 includes a housing 141, an end cap 142, an LED light-emitting component 143, a control circuit board 144, an energy storage module 145, an electromagnet unit 146, a limiting block 148, and a spring 149. The end cap 142 is fixedly disposed at one end of the housing 141. The control circuit board 144 and the energy storage module 145 are both fixedly disposed inside the housing 141. The control circuit board 144 integrates the LED light-emitting component 143 and a vibration sensing switch. The LED light-emitting component 143 is disposed on the side wall of the housing 141. The end cap 142 has a slide rail 1421 on its surface, and a boss 1423 is provided in the slide rail 1421. The limiting block 148 is slidably disposed in the slide rail 1421. The spring 149 is connected between the boss 1423 and the limiting block 148. The electromagnet unit 146 is disposed on the surface of the boss 1423 and can fit against the surface of the limiting block 148. The limiting block 148 can enter the limiting groove 122. A receiving coil is provided on the surface of the end cap 142 at a position corresponding to the energy storage module 145.

[0031] Please see Figures 2 to 8 Furthermore, the bottom of the mounting cavity 114 is provided with two sets of positioning holes 115, and the end of the outer shell 141 opposite to the end cover 142 is provided with two sets of positioning pins 147. The two sets of slide rails 1421 correspond to the positions of the two sets of positioning pins 147 respectively. The surface of the end cover 142 is symmetrically provided with slots 1422. The surface difference between the limiting block 148 and the end cover 142 is not less than the depth of the slot 1422. The light-emitting module 140 cooperates with the positioning holes 115 of the mounting cavity 114 through the positioning pins 147 to achieve circumferential positioning, ensuring that the limiting block 148 is aligned with the limiting groove 122, making assembly simple and accurate.

[0032] In this embodiment of the invention, the rigid transparent skirt 120 and the rigid transparent shell 111 are connected by threads, replacing adhesive or snap-fit, providing a more reliable mechanical fixation and allowing users to easily disassemble and reassemble, avoiding problems such as glue aging or clip wear. When the shuttlecock 100 is hit, the vibration sensor switch simultaneously triggers the LED light-emitting component 143 and the electromagnet unit 146 to be energized. The electromagnet magnetically engages with the limiting block 148, driving the limiting block 148 to slide into the limiting groove 122 at the end of the rigid transparent skirt 120, forming a temporary lock. This effectively prevents the skirt and shell from rotating relative to each other due to angle issues during the hitting process, avoiding slippage or loosening of the threaded connection, and ensuring the stability of the overall structure. After the hitting is completed, the elastic force of the spring 149 drives the limiting block 148 to disengage from the limiting groove 122, restoring it to a detachable state. Users can directly rotate the skirt to remove the light-emitting module 140, facilitating maintenance or component replacement.

[0033] Please see Figures 9 to 10In another embodiment of the present invention, a charging device is provided, the charging device including a bottom shell 210, a top cover 220, a terminal block 230 and a wireless charging unit 240, the top cover 220 being rotatably connected to the bottom shell 210, a plurality of wireless charging units 240 being symmetrically distributed about the terminal block 230, and the end cap 142 being able to overlap the surface of the wireless charging unit 240.

[0034] Please see Figure 11 Furthermore, the wireless charging unit 240 includes a rotating tube 241, a tray 242, and a wireless charging plate 243. The tray 242 is fixedly connected to one end of the rotating tube 241, and the other end of the rotating tube 241 is rotatably connected to the surface of the terminal block 230. The wireless charging plate 243 is provided on the surface of the tray 242, and the end cap 142 can contact the wireless charging plate 243. The tray 242 is provided with a limiting protrusion 244, and the limiting block 148 and the slot 1422 can both contact the surface of the limiting protrusion 244.

[0035] In this embodiment of the invention, the wireless charging unit 240 can rotate 90° around the rotating tube 241, adjusting from a horizontal storage state to a vertical charging state to adapt to the placement angle of the badminton shuttlecock 100. A plurality of wireless charging units 240 are arranged in a ring around the terminal block 230, allowing simultaneous charging of multiple shuttlecocks 100, thus improving charging efficiency. A limiting protrusion 244 is provided on the surface of the tray 242, which cooperates with the slot 1422 of the end cap 142 of the light-emitting module 140 to prevent the shuttlecock 100 from shifting during charging, ensuring stable contact between the wireless charging plate 243 and the receiving coil. Wireless charging avoids the problem of physical contact oxidation, improving charging reliability.

[0036] Working principle: During installation, firstly, the two positioning pins 147 of the light-emitting module 140 are inserted into the two positioning holes 115 at the bottom of the mounting cavity 114. On the one hand, the light-emitting module 140 is circumferentially limited within the mounting cavity 114. On the other hand, since the two sets of slide rails 1421 correspond to the positions of the two sets of positioning pins 147, the limiting block 148 is aligned with the limiting groove 122 of the flange structure 121. Then, the rigid transparent ball skirt 120 is threadedly connected to the rigid transparent shell 111. The rigid transparent ball skirt 120 can axially limit the light-emitting module 140, thereby fixing the light-emitting module 140 within the mounting cavity 114.

[0037] When the badminton shuttlecock 100 is hit or impacted, the vibration sensor switch can simultaneously energize the LED light-emitting component 143 and the electromagnet unit 146. After being energized, the LED light-emitting component 143 emits light through the rigid transparent shell 111 and the rigid transparent skirt 120. After being energized, the electromagnet unit 146 and the magnetic core 1491 are magnetically bonded. The limiting block 148 can automatically slide into the limiting groove 122, which can prevent the rigid transparent shell 111 and the rigid transparent skirt 120 from rotating relative to each other due to the hitting angle. This prevents the rigid transparent skirt 120 from slipping or loosening between the rigid transparent shell 111 and the rigid transparent skirt 120. This process is completed automatically at the moment of impact, effectively preventing the relative rotation between the rigid transparent skirt 120 and the rigid transparent shell 111 due to the hitting angle. Compared to existing static fixation methods such as adhesive or snap-fit, electromagnetic limiting is activated only when the shuttlecock is hit or subjected to a certain degree of vibration, avoiding wear or fatigue caused by long-term mechanical stress. For example, when hitting a powerful smash or at an angle, the shuttlecock 100 is easily subjected to torque, and the electromagnetic limiting can lock instantly, preventing slippage. After the hit or impact disappears, the elasticity of the spring 149 drives the limiting block 148 to disengage from the limiting groove 122. Users can directly remove the internal light-emitting module 140 by rotating the rigid transparent skirt 120, which is convenient for maintenance and replacement.

[0038] When charging is needed, open the top cover 220 and rotate the wireless charging unit 240 90 degrees around the axis of the rotating tube 241. This allows the horizontally placed wireless charging unit 240 to be adjusted to a vertical position. Place the end cap 142 (receiving coil) of the light-emitting module 140 on the surface of the wireless charging plate 243. The limiting protrusion 244 and the card slot 1422 are used to prevent the shuttlecock 100 from becoming loose during charging. Several wireless charging units 240 are arranged in a ring around the terminal block 230, which can charge multiple shuttlecocks 100 at the same time. After charging is finished, keep the wireless charging unit 240 in a horizontal position in the bottom shell 210. After closing the top cover 220, it is easy for the user to carry.

[0039] In summary, when the badminton shuttlecock 100 of this application is hit or impacted, the vibration sensing switch is triggered, which simultaneously energizes the LED light-emitting component 143 and the electromagnet unit 146. The energized electromagnet unit 146 generates magnetic force, which adheres to the surface of the limiting block 148, overcoming the elastic force of the spring 149, and driving the limiting block 148 to slide along the slide rail 1421 and insert into the limiting groove 122 at the end of the rigid transparent shuttlecock skirt 120. This effectively prevents relative rotation between the rigid transparent shuttlecock skirt 120 and the rigid transparent shell 111 caused by the hitting angle, ensuring reliability during use and reducing maintenance costs.

[0040] When the badminton shuttlecock 100 is not in a hitting state, the vibration sensing switch is turned off, the electromagnet unit 146 is de-energized, and the elastic force of the spring 149 drives the limit block 148 to automatically exit the limit groove 122 and return to a free state. The user can directly rotate the rigid transparent shuttlecock skirt 120 to remove the light-emitting module 140 for maintenance or replacement.

[0041] The tray 242 in this application has a limiting protrusion 244 on its surface, which cooperates with the slot 1422 of the end cover 142 of the light-emitting module 140. When charging, the badminton shuttlecock 100 is placed on the wireless charging plate 243. The engagement of the limiting protrusion 244 and the slot 1422 prevents the badminton shuttlecock 100 from shifting or rotating during the charging process, ensuring the stability of the charging contact, avoiding charging interruption caused by vibration, and improving charging efficiency. At the same time, the wireless charging unit 240 is rotatable to adapt to different placement methods, improving user experience and portability.
