Description

Technical Field

[0001] This utility model relates to the field of rechargeable light-emitting ball technology, and in particular to a light-emitting ball that can be magnetically charged. Background Technology

[0002] Balls are common sporting goods, often used for physical exercise or activities. To facilitate use in environments with poor lighting, many balls have been equipped with an electric light source module inside the ball, enabling the ball to emit light and thus expanding its usability and increasing the fun of the game.

[0003] I registered a replaceable battery-powered light bulb in 2019 and obtained a patent in 2020. I then applied for a patent for a TYPE-C (USB) rechargeable light bulb, which is currently under examination.

[0004] The aforementioned luminous ball has several drawbacks, including insufficient battery life, easily damaged plug-in ports, and the charging cable becoming detached due to the ball's rolling motion during charging. It is also not effectively waterproof. To address these shortcomings, improve the safety and convenience of using the luminous ball, and highlight its application in water-based environments such as swimming pools and beaches, this patent application has been filed. Utility Model Content

[0005] To improve charging safety, compatibility, protection of the charging port, and waterproofing performance, this application provides a magnetically rechargeable luminous ball.

[0006] The magnetically rechargeable luminous sphere provided in this application adopts the following technical solution:

[0007] A magnetically rechargeable luminous sphere includes a sphere and a charging cable. The sphere has a protective shell, and the protective shell has an electric light source module for emitting light. The charging cable has a first magnetic block, and the protective shell has a second magnetic block. The first magnetic block can abut against and be magnetically attracted to the second magnetic block. The charging cable is used to charge the electric light source module. The electric light source module has a battery for power supply. The protective shell has a first conductive block electrically connected to the battery. The charging cable has a charging block, the first magnetic block is disposed on the charging block, and the charging block has a second conductive block. The second conductive block is electrically connected to the charging cable through a built-in circuit of the charging block.

[0008] By adopting the above technical solution, when the charging cable charges the light source module, the first magnetic block adheres to the second magnetic block and is magnetically attracted to it, thus fixing the charging cable to the spherical protective shell. When the first magnetic block adheres to and attracts the second magnetic block, the second conductive block adheres to the first conductive block, and the charging cable is electrically connected to the battery of the light source module through the first and second conductive blocks for charging. This improves the stability of the connection between the charging cable and the sphere during charging, reduces the possibility of the charging cable falling off during charging, and enhances the stability of the charging connection. At the same time, magnetic charging eliminates the need for careful alignment and plugging / unplugging of the charging interface as required by traditional charging methods. In dim light or emergency situations, simply bringing the magnetic charging cable close to the device allows for quick connection and charging, greatly saving time and effort, and making it convenient for children to use. Furthermore, the frequent plugging and unplugging of the charging cable in traditional charging methods can easily cause wear and tear on the device's charging interface, affecting the charging effect and even damaging the interface. Magnetic charging, through magnetic attraction, avoids excessive plugging and unplugging, effectively extending the lifespan of the device's charging interface. Taking frequently used mobile phones as an example, the wear and tear on the charging interface from long-term use of magnetic charging is significantly less than that from using traditional charging cables. Magnetic charging also has a certain degree of anti-pull function. When the charging cable is accidentally pulled, the magnetic interface will automatically separate, preventing damage to the charging cable or device from falling from a height due to excessive pulling, or even causing safety accidents. At the same time, the charging cable can use common charging cables for mobile phones or other electronic devices, thus improving applicability. Simultaneously, power is achieved through the contact of the first and second conductive blocks. When not charging, the protective cover isolates the light source module, reducing the possibility of liquid contact damaging the light source module. This allows the luminous sphere to be used in scenarios where it directly contacts liquids, such as swimming pools. In existing technologies, the luminous sphere cannot directly contact liquids because of the charging interface. This application greatly expands the applicability of the luminous sphere.

[0009] Preferably, the protective shell is provided with a charging hole, the first conductive block is disposed in the charging hole, and the second conductive block can be inserted into the charging hole and abut against the first conductive block and electrically connected to the first conductive block.

[0010] By adopting the above technical solution, the first conductive block is placed inside the charging hole, which reduces the possibility of the first conductive block being damaged by impact and improves durability.

[0011] Preferably, the sphere is provided with a mounting sleeve, which is disposed inside the mounting hole. The protective shell is inserted into the mounting sleeve. The sphere is also provided with a rubber cap, which is disposed inside the mounting hole and seals the mounting hole. The rubber cap is fitted onto the mounting sleeve, and the charging hole passes through the rubber cap.

[0012] By adopting the above technical solution, the protective cover is sealed inside by installing a rubber sleeve and a rubber cap, thereby improving waterproof performance, reducing the possibility of liquid penetration affecting the first conductive block, and improving overall durability.

[0013] Preferably, the sphere is provided with a mounting hole, the protective shell is inserted into the mounting hole, the inner wall of the mounting hole is provided with a sealing groove, a sealing plate that can be inserted into the mounting hole is slidably disposed in the sealing groove, the charging block can be inserted into the mounting hole, and the sealing plate is provided with anti-slip texture.

[0014] By adopting the above technical solution, the sealing plate can be inserted into the mounting hole to seal the mounting hole, thereby working with the protective shell to achieve the effect of waterproofing and sandproofing, reducing the possibility of liquid penetration affecting the first conductive block, improving overall durability, and the anti-slip texture enhances the surface friction of the sealing plate, thereby making it easier for users to push the sealing plate to move and improving the convenience of use.

[0015] Preferably, the inner wall of the mounting hole is provided with a sealing groove, and the sealing plate is provided with a sealing block, which can be inserted into the sealing groove.

[0016] By adopting the above technical solution, the sealing block is inserted into the sealing groove, which improves the overall sealing performance, further reduces the possibility of liquid or sand penetrating into the installation hole, and improves durability.

[0017] Preferably, the sphere is provided with a wire-passing groove that communicates with the sealing groove, through which the charging cable can pass.

[0018] By adopting the above technical solution, the charging cable passes through the cable groove after the charging block is inserted into the mounting hole, which allows the connection between the charging cable and the charging block to be fully extended, thereby reducing the possibility of the charging cable being squeezed and deformed by the inner wall of the charging groove and mounting hole, and improving the overall durability.

[0019] Preferably, the protective shell is provided with a charging slot, the first magnetic block is disposed in the charging slot, the charging block can be inserted into the charging slot, the sealing plate can be inserted into the charging slot, the sealing plate is provided with a third magnetic block, the third magnetic block can abut against the first magnetic block and be magnetically attracted to the first magnetic block.

[0020] By adopting the above technical solution, the sealing plate is inserted into the charging slot to achieve better sealing. At the same time, the third magnetic block is attached to the first magnetic block and magnetically attracted to the first magnetic block, thereby fixing the sealing plate in the sealed state, improving the stability of the sealing plate in sealing the charging slot, and thus facilitating the normal use of the sphere.

[0021] Preferably, the inner wall of the enclosed slot is provided with a first limiting groove, the inner wall of the charging slot is provided with a second limiting groove, the enclosed plate is provided with a limiting block, the limiting block is inserted into the first limiting groove and can slide in the first limiting groove, and the limiting block can be inserted into the second limiting groove and slide in the second limiting groove.

[0022] By adopting the above technical solution, the limiting block can move in the first limiting groove and can be inserted into the second limiting groove, thereby improving the stability of the sliding of the sealing plate. The insertion of the limiting block into the second limiting groove can further reduce the possibility of liquid or sand penetrating into the charging groove, further improving the sealing reliability, so as to facilitate the normal use of the sphere.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By setting up a sphere, an electric light source module, a charging cable, a protective shell, a first magnetic block and a second magnetic block, the electric light source module inside the sphere can be charged through the charging cable when it is out of power. During charging, the first magnetic block on the charging cable is attached to the second magnetic block, so that the first magnetic block and the second magnetic block are magnetically attracted, thereby improving the stability of the charging connection and reducing the possibility of the charging cable falling off during the charging process.

[0025] 2. By setting up a battery, charging port, first conductive block, second conductive block and charging block, during charging, the charging block on the charging cable is attached to the protective shell, so that the first magnetic block attracts the second magnetic block. At the same time, the second conductive block is inserted into the charging port and pressed against the second conductive block. At this time, the battery is connected to the charging cable through the internal circuit of the second conductive block, the first conductive block and the charging block. The charging cable is connected to the power source through the plug or USB interface, thereby completing the charging. The operation is simple and convenient and easy to use.

[0026] 3. By setting mounting holes, sealing grooves, and sealing plates, the sealing plate in the sealing groove can be slidably inserted into the mounting holes, thereby sealing the second magnetic block and the charging hole. This ensures that the second magnetic block and the charging hole are not exposed during normal use of the sphere, reducing the possibility of the first conductive block inside the second magnetic block and the charging hole being damaged by collisions during use. At the same time, it reduces the possibility of liquids and sand penetrating into the charging hole, clogging the charging hole, or damaging the first conductive block, thus improving durability.

[0035] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0036] Embodiment 1 of this application discloses a magnetically rechargeable luminous sphere. (See also...) Figures 1 to 2 The device includes a sphere 1, an electric light source module 2, and a charging cable 3 with a plug at one end (the length of the charging cable 3 can be adjusted according to actual use). The sphere 1 is made of a light-transmitting elastic material and is hollow inside. The electric light source module 2 is an LED light and is located inside the sphere 1. The surface of the sphere 1 has a mounting hole 11 that communicates with the interior. A mounting sleeve 111 is fitted inside the mounting hole 11 and is glued to the interior of the mounting hole 11. The mounting sleeve 111 is inserted into the cavity of the sphere 1 and has an opening at the top. The electric light source module 2 is covered with a protective shell 4 made of plastic material and sealed. The protective shell 4 is inserted into the mounting sleeve 111. A rubber cap 43 made of elastic waterproof material is glued to the mounting sleeve 111. After the deformed side wall of the rubber cap 43 protrudes, it is inserted into the groove on the inner wall of the mounting hole 11. The surface of the rubber cap 43 is flush with the outer surface of the sphere 1.

[0037] The rubber cover 43 has two second magnetic blocks 411 inside. A charging block 31 is located on the section of the charging cable 3 furthest from the plug. A first magnetic block 311 is fixedly mounted on the bottom wall of the charging block 31. The first magnetic blocks 311 can abut against and magnetically attract the second magnetic blocks 411 one by one. The charging cable 3 is used to charge the light source module 2. By having the first magnetic blocks 311 attract the second magnetic blocks 411, the sphere 1 and the charging block 31 are fixedly connected, improving the stability of the charging connection.

[0038] For ease of use, please refer to Figure 1 and Figure 2 The electric light source module 2 contains a battery 21 for power supply. A first conductive block 211 (not shown in detail in the figure) is fixedly installed in the electric light source module 2 and electrically connected to the battery 21 via wires. A charging hole 42 is provided on the rubber cover 43 and the protective shell 4, penetrating the rubber cover 43. The first conductive block 211 is fitted into the charging hole 42 and waterproofed, ensuring that contact with water will not affect or damage the battery. The charging block 31 has two fixed second conductive blocks 312, which are electrically connected to the charging cable 3 via internal circuitry. The second conductive blocks 312 can be fitted into the charging hole 42 and press against the first conductive block 211, connecting them electrically. The charging cable 3 plug is inserted into the power grid, thus connecting the battery 21 to the power grid for charging. During charging, the second conductive block 312 is inserted into the charging hole 42, pressing against the first conductive block 211 to connect the circuit, thereby charging the battery 21 of the light source module 2. The operation is simple and convenient, and easy to use. At the same time, the light-emitting ball of this application is charged through conductor contact, and the rubber cover 43 is provided to cooperate with the installation of the rubber sleeve 111 and the protective shell 4, which greatly reduces the possibility of liquid penetrating into the light source module 2 and damaging the light source module 2. This allows the light-emitting ball to be used in scenarios where it comes into direct contact with liquid, such as swimming pools. In the prior art, the light-emitting ball 1 cannot directly contact the liquid because of the charging interface. This application greatly expands the applicability of the light-emitting ball.

[0039] Embodiment 2 of this application provides a magnetically rechargeable luminous sphere, which, compared with Embodiment 1, is characterized in that, with reference to... Figures 3 to 5The protective shell 4 and the mounting sleeve 111 are both made of elastic material and integrally molded. The LED beads of the light source module 2 are located outside the protective shell 4 and are set inside the cavity of the sphere 1. The surface of the cover 43 is lower than the outer surface of the sphere 1, and the surface of the cover 43 is provided with a charging groove 41 that connects to the charging hole 42. The second magnetic block 411 is set on the bottom wall of the charging groove 41. At the same time, the inner wall of the mounting hole 11 is also provided with a sealing groove 12. The sealing groove 12 is set in an arc shape to fit the curvature of the surface of the sphere 1. An arc-shaped sealing plate 5 is adapted to slide inside the sealing groove 12. The sealing plate 5 is made of elastic material. The sealing plate 5 can be adapted to be inserted into the charging groove 41. The surface of the sealing plate 5 is provided with concave anti-slip texture 52 to facilitate sliding. The inner wall of the mounting hole 11 away from the sealing groove 12 is provided with a sealing groove 13. The sealing plate 5 is fixedly provided with a sealing block 53 that is functionally adapted to be inserted into the sealing groove 13. The outer surface of the sphere 1 is provided with a wire groove 131 that connects to the sealing groove 13 for the charging cable 3 to pass through. The sealing plate 5 is slidably inserted into the charging slot 41 to isolate the second magnetic block 411 from the charging hole 42, reducing the possibility of liquid and sand penetrating into the charging hole 42 and clogging the charging hole 42 or damaging the first conductive block 211, thus improving durability.

[0040] To improve ease of use, refer to Figure 6 and Figure 7 A third magnetic block 51 is fixedly installed on the bottom wall of the sealing plate 5. The third magnetic block 51 can fit against the first magnetic block 311 and be magnetically attracted to the first magnetic block 311. A first limiting groove 121 is provided on both sides of the inner wall of the sealing groove 12. A second limiting groove 412 communicating with the first limiting groove 121 is provided through the inner wall of the charging groove 41. Elongated limiting blocks 54 are provided on both sides of the sealing plate 5. The limiting blocks 54 are slidably disposed in the first limiting groove 121 and can slide into the second limiting groove 412. The sliding of the limiting blocks 54 within the first limiting groove 121 and the second limiting groove 412 improves the sealing performance and enhances the stability of the sliding of the sealing plate 5. When not charging, the sealing plate 5 is inserted into the charging groove 41, causing the third magnetic block 51 to fit against the first magnetic block 311 and be magnetically attracted, thereby improving the sealing stability of the sealing plate 5.

[0041] The implementation principle of a magnetically rechargeable luminous ball according to an embodiment of this application is as follows: By setting a first magnetic block 311 and a second magnetic block 411, during charging, the sealing plate 5 is pushed back into the sealing groove 12 to make room for the charging groove 41. The charging block 31 is inserted into the charging groove 41 and the second conductive block 312 is inserted into the charging hole 42 to abut against the first conductive block 211, thereby connecting the entire charging circuit. At this time, the first magnetic block 311 attracts the second magnetic block 411, thereby fixing the ball 1 and the charging block 31 by magnetic fixation, thereby improving the stability of the charging connection.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
