[0023] This invention provides an ice hockey puck.

[0024] Refer to Figures 1 to 4. In one embodiment of the present invention, the ice hockey puck includes a housing 100, a light-emitting device 200, a power supply 300, and a magnetic induction switch 400.

[0025] The housing 100 is translucent in at least a portion thereof. The light-emitting device 200 is installed inside the housing 100 and is capable of emitting light to the outside through the translucent portion of the housing 100. The light-emitting device 200 is electrically connected to the power supply 300. The magnetic induction switch 400 is installed inside the housing 100 and is electrically connected to the power supply 300, and is used to control the conduction or interruption of the circuit between the light-emitting device 200 and the power supply 300 based on changes in an external magnetic field.

[0026] In this embodiment, the housing 100 of the ice hockey puck is made of a translucent material, preferably a semi-transparent polyurethane material. The semi-transparent polyurethane material can achieve low temperature resistance and can function normally even at minus 30 degrees Celsius. The surface of the ice hockey puck is sandblasted, which not only makes the light emission more uniform and aesthetically pleasing, but also makes the patterns formed on the surface by UV printing more beautiful and abrasion resistant. By combining the translucent housing 100 and the light-emitting device 200, the ice hockey puck becomes visible even in dark environments, improving the user experience at night or in low-light environments. Inside the ice hockey puck, there is further provided a power supply 300 that supplies power to the light-emitting device 200. To avoid power consumption when the ice hockey puck is not in use, a magnetic induction switch 400 electrically connected to a power supply 300 is provided inside the housing 100. By bringing an external magnetic object 600 close to the ice hockey puck, the ice hockey puck's illumination state can be automatically controlled when the external magnetic field changes, thereby enhancing its interactivity and appeal.

[0027] In one embodiment, the light-emitting device 200 includes a controller 210, a light-emitting element 220, a vibration sensor 230, and a circuit board 240. The light-emitting element 220 and the vibration sensor 230 are electrically connected to the controller 210. The vibration sensor 230 is used to detect vibration signals. The controller 210 is used to control the illumination or extinguishing of the light-emitting element 220 based on the vibration signals.

[0028] In this embodiment, the controller 210, the light-emitting element 220, and the vibration sensor 230 are all integrated on the circuit board 240 and electrically connected. The vibration sensor 230 is responsible for detecting the movement state of the ice hockey puck and transmits a signal to the controller 210 when the ice hockey puck is hit or moved. Based on the received vibration signal, the controller 210 controls the pass-through state of the light-emitting element 220, thereby enabling illumination or extinguishing. By combining the vibration sensor 230 and the controller 210, the ice hockey puck can automatically illuminate during movement, significantly improving the visual expressiveness of the game and the user experience, making the game process more lively and interesting.

[0029] Some ice hockey pucks use a disposable power supply design, meaning the entire unit needs to be replaced when the power runs out. This not only increases usage costs but also generates a lot of waste, which is contrary to environmental protection principles.

[0030] In one embodiment, the ice hockey puck includes a charging copper column 250. The charging copper column 250 is electrically connected to the power supply 300 and used to charge the power supply 300.

[0031] In this embodiment, when the ice hockey puck's battery level is low, simply connecting an external charging device to the charging copper column allows current to flow smoothly through the copper column to the power source, and after charging is complete, the ice hockey puck can be restored to a usable state. The charging method using a copper column is not only more durable than a typical charging port, but also has the effect of increasing the overall assembly strength of the ice hockey puck.

[0032] The durability of the rechargeable copper column increases the overall structural strength of the ice hockey puck, reducing failures due to damage to the rechargeable component and extending the lifespan of the ice hockey puck. At the same time, repeated recharging allows the ice hockey puck to function continuously, avoiding resource waste and waste generation caused by frequent puck replacement. This not only puts environmental protection principles into practice but also reduces costs in the long term.

[0033] Two charging copper poles 250 are provided and are electrically connected to the power supply 300 to charge the power supply 300. This makes charging more convenient, stable, and faster. The charging copper poles 250 here are seamlessly connected to the main body and do not require further potting (resin injection).

[0034] In one embodiment, the housing 100 is provided with a mounting groove 110. The light-emitting device 200 is positioned within the mounting groove 110. An adhesive layer is provided between the light-emitting device 200 and the mounting groove 110. The adhesive layer is used for waterproofing and moisture protection.

[0035] In this embodiment, a mounting groove 110 is provided in the center of the housing 100, and the light-emitting device 200 is fixed inside it. To ensure that the light-emitting device 200 remains stable and free from rattling during the movement of the ice hockey puck, an adhesive layer is provided between the light-emitting device 200 and the mounting groove 110. By injecting liquid polyurethane adhesive using a potting method, the light-emitting device 200 is completely encased and bonded integrally with the main body of the housing 100. This significantly improves the impact resistance, moisture-proof sealing, and mounting stability of the device.

[0036] In one embodiment, the bottom surface of the housing 100 is provided with a first opening 120 and a charging positioning hole 130. The charging positioning hole 130 is used for positioning the charging device 700. The first opening 120 communicates with the mounting groove 110. One end of the charging copper column 250 is connected to the first opening 120 to form a charging interface 140. The other end of the charging copper column 250 is electrically connected to the circuit board 240.

[0037] In this embodiment, since two charging copper columns 250 are provided, two corresponding first openings 120 are also provided. One end of the charging copper column 250 is connected to the circuit board 240, and the other end is connected in alignment with the first opening 120 to form a charging interface 140. The charging positioning hole 130 of the housing 100 is used to position the charging device 700. The structure of the first opening 120 and the charging positioning hole 130 enables high-precision positioning and connection of the charging interface 140. This design not only improves the stability and reliability of the charging interface 140, but also enhances the usability and safety of the ice hockey puck.

[0038] In one embodiment, at least one light-emitting element 220 is provided on the side of the light-emitting device 200 facing the charging interface 140. The light-emitting element 220 is arranged along the circumferential direction of the circuit board 240.

[0039] In this embodiment, the light-emitting device 200 is provided with a light-emitting element 220. The light-emitting element 220 can be a light strip, a lamp chip, a light bulb, etc. Preferably, in this embodiment, an LED lamp chip is used as the light-emitting element 220, and multiple LED lamp chips are arranged along the circumferential direction of the circuit board 240. This allows, firstly, to maintain the weight balance around the ice hockey puck, and secondly, to make the light source of the light-emitting device 200 more uniform when projected onto the main body. LEDs have low power consumption and a long lifespan, so labor costs and replacement costs can be reduced. In addition, LED lamp chips do not contain harmful substances such as mercury, making them environmentally friendly. At the same time, the light-emitting device can emit light of different colors, which can increase children's interest in ice hockey games.

[0040] In one embodiment, the housing 100 includes a load-bearing cover 150. A groove 160 is provided on the top surface of the housing 100. The groove 160 communicates with the mounting groove 110. The load-bearing cover 150 is detachably fitted over the groove 160.

[0041] In this embodiment, the main body of the housing 100 includes a weighted cover 150. The weighted cover 150 is detachably installed in a groove 160 on the top surface of the housing 100. Because the weighted cover 150 has a certain weight, it helps maintain the balance of the ice hockey puck and makes it less likely to tip over. This not only improves the balance and stability of the ice hockey puck but also makes it easier to attach and detach the light-emitting device 200.

[0042] In one embodiment, the ice hockey puck further includes a fastening member 170. The fastening member 170 includes a screw 171 and a nut 172. The load cover 150 is provided with a first mounting hole 151. The bottom surface of the housing 100 is provided with a second mounting hole 152. The second mounting hole 152 penetrates the top and bottom surfaces of the housing 100. The nut 172 is attached to the second mounting hole 152. The screw 171 is inserted through the first mounting hole 151 into the second mounting hole 152 and connected to the nut 172.

[0043] In this embodiment, the ice hockey puck further employs a screw 171 and nut 172 structure to auxiliaryly fix the light-emitting device 200. Specifically, the weight-relief cover 150 is provided with a first mounting hole 151, and the bottom surface of the housing 100 is provided with a corresponding second mounting hole 152. During assembly, the weight-relief cover 150 is firmly fixed to the housing 100 by passing the screw 171 through the first mounting hole 151 and the second mounting hole 152 in sequence, and then tightening it with the nut 172. This not only simplifies the assembly process of the housing 100 and the weight-relief cover 150, but also greatly improves the stability of the connection between the two.

[0044] See also Figures 3 and 8. A third mounting column 180 is provided within the mounting groove 110, and at least one positioning groove 241 is formed in the circuit board 240. When the circuit board 240 is mounted in the cavity of the housing 100, high-precision positioning is achieved by the fitting of the third mounting column 180 and the positioning groove 241, thereby further enhancing the fixing effect of the light-emitting device 200.

[0045] Referring to Figures 5 to 7, the present invention further provides a charging device. The charging device includes the ice hockey puck described in each of the embodiments described above and a charging base 500.

Since the charging device employs the technical solutions of all the embodiments described above, it has all the beneficial effects brought about by at least the technical solutions of the embodiments described above. Details will not be described in detail here.

[0046] In one embodiment, the charging base 500 includes an upper housing 510, a lower housing 520, and a poleless charging circuit 530. The upper housing 510 and the lower housing 520 are fitted together by overlapping them. At least one first mounting post 511 is provided on the side of the upper housing 510 facing the lower housing 520. A third mounting hole 512 is provided at the tip of one end of the first mounting post 511 facing the lower housing 520. A second mounting post 521 is provided inside the lower housing 520, facing the first mounting post 511. The second mounting post 521 is connected to the third mounting hole 512. A reinforcing rib 522 is provided inside the lower housing 520. The reinforcing rib 522 is used to fix the poleless charging circuit 530.

[0047] In this embodiment, the upper housing 510 and the lower housing 520 are fitted together by inserting the first mounting column 511 and the second mounting column 521 into each other. The third mounting hole 512 at the tip of the first mounting column 511 and the projection at the top of the second mounting column 521 engage and lock together, so that it can be locked without additional screws 171. The non-polarized charging circuit 530 is located inside the cavity of the lower housing 520, and the lattice structure of the reinforcing ribs 522 clamps and fixes it from all sides, and it is precisely aligned to the mounting position of the charging pin 540.

[0048] In one embodiment, the charging base 500 further includes a charging pin 540. The charging pin 540 is connected to the poleless charging circuit 530. The lower housing 520 is provided with a second opening 523 and a charging positioning column 524. The charging pin 540 penetrates the second opening 523, with a portion of it positioned outside the lower housing 520.

[0049] In this embodiment, the charging pin 540 is passed through the second opening 523 of the lower housing 520, and a portion of it is positioned outside the lower housing 520, thereby connecting the charging positioning column 524 to the ice hockey puck and improving the accuracy and stability of charging. The charging base 500 further includes a charging cable 550. The charging cable 550 transmits current by connecting to an external power source and electrically connects to an external device via the charging pin 540, improving convenience and efficiency of use.

[0050] Refer to Figures 8 to 10. The present invention further provides an ice hockey puck kit. The ice hockey puck kit includes the ice hockey puck described in each of the above embodiments and the charging device described in each of the above embodiments.
