[0028] To address the shortcomings of existing Rubik's Cube charging boxes, this application provides a smart Rubik's Cube charging box that enables charging and interactive operations of the Rubik's Cube via spring pins 4. The charging box integrates a display screen 5 that can provide users with teaching, competition, and solving timing services, significantly improving the user experience.

[0029] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0030] like Figures 1 to 5 As shown in the figure, the present utility model provides a Rubik's Cube smart charging box, including a box body 1 with a receiving cavity. The box body 1 is provided with a control motherboard 2. The control motherboard 2 is connected to a battery 3, a spring pin 4 and a display screen 5. The spring pin 4 extends into the receiving cavity and the display screen 5 is disposed on the outer side wall of the box body 1.

[0031] When the Rubik's Cube is placed into the receiving cavity, the Rubik's Cube is connected to the control motherboard 2 via the spring pin 4, so that the battery 3 powers the Rubik's Cube and the control motherboard 2 exchanges data with the Rubik's Cube; when the Rubik's Cube is removed from the spring pin 4, the control motherboard 2 establishes a Bluetooth connection with the Rubik's Cube and interacts with it through the display screen 5.

[0032] Specifically, when the Rubik's Cube is not placed in the charging case, the connection between the spring pin 4 and the control board 2 is disconnected. After the Rubik's Cube is placed in the charging case, the spring pin 4 contacts the charging pad of the internal circuitry of the Rubik's Cube. Under the action of the Rubik's Cube, the spring pin 4 is pushed towards the control board 2, allowing it to connect to the circuitry of the control board 2 and thus enabling charging via the battery 3. After the spring pin 4 connects the Rubik's Cube and the control board 2, they can exchange data to achieve Rubik's Cube authentication and identification, such as the Rubik's Cube's unique ID, the charging case's battery level, and time display. When the Rubik's Cube is removed from the charging case, the control board 2 can establish a connection with the Rubik's Cube via its built-in Bluetooth module, without requiring manual pairing by the user. After the charging case connects to the smart Rubik's Cube via Bluetooth, it can connect to the cloud server via WIFI or 4G to realize the Rubik's Cube's teaching, competition, timing, and other game functions. Of course, the connection between the charging case and the Rubik's Cube can also be achieved through other methods. In addition, the control board 2 can also send the Rubik's Cube's specific battery level information to a mobile phone or the cloud.

[0033] The control motherboard 2 connects the cube to the charging box via Bluetooth, WiFi, and 4G. Bluetooth connections feature short transmission distances and low power consumption, while WiFi and 4G connections offer wide coverage and fast transmission speeds. The cube also identifies itself while charging, and the control motherboard 2 automatically connects after the cube is removed from the charging box.

[0034] In this embodiment, the smart charging box is equipped with a battery 3, a display screen 4, buttons, a control motherboard 2 with an MPU processing unit, Bluetooth Low Energy, Wi-Fi, and 4G connection modules, etc., and can charge the smart Rubik's Cube. In addition to charging the Rubik's Cube, the smart charging box uses Bluetooth Low Energy to connect to the smart Rubik's Cube, and Wi-Fi and 4G to connect to the cloud server. The charging box can provide functions such as teaching, competition, and solving timer for the smart Rubik's Cube.

[0035] In a preferred embodiment, the control motherboard 2 is equipped with a gyroscope control circuit. This gyroscope control circuit controls the cube's attitude calibration based on the orientation detected by the spring pin 4. During the process of placing the cube into the charging case, data interaction and charging are achieved through the spring pin 4. During this process, the control motherboard 2 also includes a gyroscope control circuit for controlling the cube's gyroscope, and interactive operation is achieved through the display screen 5. When the user places the cube into the charging case, they can control it through the display screen 5. The gyroscope control circuit calibrates the gyroscope data inside the cube by detecting its orientation and correctly renders the cube's orientation information and the specific positions of the cube's color blocks on the display screen 5.

[0036] In a preferred embodiment, the display screen 5 includes a front cover 51, a protective screen 52, an LCD screen 53, and a touch sensing module 54. The front cover 51 has a window, the protective screen 52 is disposed on the window, and the front cover 51 is disposed on one side wall of the housing body 1. The LCD screen 53 and the touch sensing module 54 are connected to the control motherboard 2, and the touch sensing module 54 is used to wake up the LCD screen 53. In this embodiment, the LCD screen 53 can be any one of an LCD display, an OLED display, or an e-ink screen. In a preferred embodiment, the LCD screen 53 is an LCD display 5, which is relatively inexpensive and can reduce the overall cost after assembling the display screen 5.

[0037] In a preferred embodiment, the power interface 6 is located on the box body 1. The power interface 6 is used to connect the power cord and the power interface 6 is connected to the control motherboard 2 for charging the battery 3. The battery 3 can be a polymer lithium battery 3, lithium iron phosphate battery 3, or other lithium batteries 3.

[0038] In a preferred embodiment, the aforementioned box body 1 includes an upper shell 11, a lower shell 12, an upper cover 13, and a lower cover 14. The upper shell 11 covers the lower shell 12 and forms a cavity for housing the upper cover 13 and the lower cover 14. The upper cover 13 is disposed on the upper shell 11, and the lower cover 14 is disposed on the lower shell 12. The upper cover 13 is rotatably connected to the lower cover 14 via a pivot. The upper cover 13 and the lower cover 14 form the receiving cavity. A sandwich cavity is formed between the lower cover 14 and the lower shell 12. The control board 2 and the battery 3 are disposed in the sandwich cavity. The spring pin 4 penetrates the lower cover 14 and extends into the receiving cavity. When the upper cover 13 is closed on the lower cover 14, it presses the Rubik's Cube tightly into the receiving cavity. The tip of the spring pin 4 slides inside the needle tube and contacts the charging pad of the circuit board inside the Rubik's Cube. The spring provided inside the spring pin 4 provides elasticity to establish an electrical connection between the tip of the pin and the circuit board.

[0039] Furthermore, the upper cover 13 is provided with a first magnetic attraction component 15, and the lower cover 14 is provided with a second magnetic attraction component 16. When the upper cover 13 is closed to the lower cover 14, the first magnetic attraction component 15 and the second magnetic attraction component 16 are magnetically attracted to each other.

[0040] Furthermore, the upper cover 13 is provided with a first magnet groove on both sides, and the lower cover 14 is provided with a second magnet groove on both sides. The first magnetic attraction component 15 is provided on the first magnet groove, and the second magnetic attraction component 16 is provided on the second magnet groove.

[0041] Furthermore, a detection magnet 17 is provided on one side of the upper cover 13, and a Hall sensor 18 is connected to the control motherboard 2. The detection end of the Hall sensor 18 is located on one side of the lower cover 14. When the upper cover 13 is closed to the lower cover 14, the detection magnet 17 and the detection end of the Hall sensor 18 are opposite to each other. The Hall sensor 18 is connected to the control motherboard 2 by soldering to improve the stability of the circuit.

[0042] Furthermore, the upper cover 13 is connected to the upper shell 11 by a snap-fit, and the lower cover 14 is connected to the lower shell 12 by a thread. The upper cover 13 is detachably mounted on the upper shell 11. A pivot is provided on one side wall of the lower cover 14, allowing the upper cover 13 to rotate relative to the lower cover 14. A detection magnet 17 is mounted on the upper cover 13, and the magnet rotates with the upper cover 13. A Hall sensor 18, connected to the control motherboard 2 and mounted on the lower cover 14, can sense changes in the magnetic field of the detection magnet 17, thereby generating corresponding signals. Based on these signals, corresponding decisions can be made. For example, issuing a first signal wakes up the charging case and puts it into standby mode; issuing a second signal allows the charging case to charge the cube; and issuing a third signal prohibits the charging case from charging the cube, thus avoiding the need to unplug the traditional cable to cut off the power to the charging case, resulting in a better user experience. In addition, the Hall sensor 18 can also send the opening and closing action message of the charging case to the display screen 5 or the user terminal.

[0043] Correspondingly, the Hall sensor 18 can detect the open and closed state of the cover 13, and can wake up the device and turn on the display screen 5 when the state changes.

[0044] In a preferred embodiment, the bottom of the aforementioned box body 1 is also provided with a support lever 7 and pads located at the four corners of the bottom of the box body 1. The support lever 7 can adjust the display angle of the display screen 5, thereby facilitating user viewing.

[0045] Based on the above specific implementation, the charging box can also be equipped with a reset button, which allows users to restore the device to factory settings and resolve some problems that cannot be solved well.

[0046] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
