[0027] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] like Figures 1 to 5As shown, the present invention provides an electric ball bearing, comprising a shell 1, an inner shell 2, and a drive component. The shell 1 is spherical, and a first mounting groove 104 is provided on the inner wall of the shell 1. The inner shell 2 is disposed inside the shell 1, and a first clearance hole is provided on the inner shell 2. The drive component is disposed inside the inner shell 2, and the center of gravity of the drive component is spaced apart from the center of the shell 1. The drive component includes a motor 3, a control circuit 7, and a battery 4. The motor 3 and the battery 4 are electrically connected to the control circuit 7. The output shaft 301 of the motor 3 passes through the first clearance hole and is inserted into the first mounting groove 104. The output shaft 301 and the groove wall of the first mounting groove 104 are pressed together so that the output shaft 301 drives the inner shell 2 to rotate when rotating. The control circuit 7 controls and adjusts the speed of the motor 3 so that the motor 3 can operate according to the set parameters. By setting up control circuit 7, motor 3 can be controlled to operate according to set parameters to change the original speed of motor 3. This eliminates the need for a reduction gear mechanism in the electric ball, simplifying the mechanical structure of the electric ball, facilitating production, and reducing malfunctions. Control circuit 7 can also control the speed of output shaft 301, thereby controlling the rolling speed of the electric ball and increasing the fun of playing.

[0030] In this embodiment, the control circuit 7 uses PWM (Pulse Width Modulation) control to control the motor 3. The control circuit 7 can select a preset control mode to achieve timing, delay, low speed, high speed, speed variation according to a preset mode, or control the output shaft 301 of the motor 3 to rotate forward or backward. By adjusting the control circuit 7 and the preset program, various operating modes can be achieved, such as low speed, high speed, variable speed, interval, delay, and other control modes. By setting the control circuit 7, the operation mode of the rolling ball can be diversified, increasing the fun for pets during play.

[0031] Of course, the "set parameters" can be PWM speed control parameters, or the angular velocity, current, voltage, and any other parameters that can change the speed of motor 3. By controlling and adjusting to change the speed of motor 3, motor 3 can have multiple rotation modes. For example, motor 3 can operate at a set high speed, a set low speed, a set other speed, or according to a set program.

[0032] Specifically, the control circuit 7 is equipped with a control button 701. The inner shell 2 includes a shell body and an elastic block, which are integrally formed. The elastic block and the control button 701 are directly opposite each other. The outer shell 1 is provided with a second clearance hole 103, the axis of which coincides with the axis of the output shaft 301. The elastic block extends into the second clearance hole 103. By making the shell body and the elastic block integrally formed, the connection strength between the elastic block and the shell body can be improved, and the probability of the elastic block detaching from the shell body can be reduced. By making the elastic block extend into the second clearance hole 103, the elastic block can act as a pivot, increasing the support points between the outer shell 1 and the inner shell 2, so that the inner shell 2 can rotate stably around the axis of the output shaft 301.

[0033] Specifically, the elastic block includes a protrusion 203 and an elastic arm 204. One end of the protrusion 203 is directly opposite the control button 701, and the other end extends into the second clearance hole 103. The housing body is provided with a connecting hole, and the protrusion 203 is connected to the wall of the connecting hole through the elastic arm 204. By providing the elastic arm 204, the position of the protrusion 203 can be moved by the elastic force of the elastic arm 204, so that the control button 701 of the control circuit 7 can be pressed by the protrusion 203; by providing one end of the protrusion 203 to extend into the clearance hole, it is convenient to press the protrusion 203, thereby facilitating the opening and closing of the electric ball.

[0034] Specifically, the driving component includes a battery 4 and a charging port 6, which are electrically connected to the control circuit 7. A third clearance hole is provided on the inner shell 2 corresponding to the position of the charging port 6. The outer shell 1 includes a detachably connected first shell 101 and a second shell 102. A first mounting groove 104 is provided on the second shell 102. When the first shell 101 and the second shell 102 are separated, the charging port 6 is exposed. By providing the battery 4, the electric ball can roll independently, reducing restrictions on the usage location. By providing the charging port 6, the battery 4 can be reused, achieving environmental protection. By providing the detachably connected first shell 101 and second shell 102, when charging is required, the first shell 101 and the second shell 102 can be separated, allowing the charging port 6 to be exposed. After charging is complete, the first shell 101 and the second shell 102 can be fixed. At this time, the outer shell 1 can cover the charging port 6, improving the appearance of the electric ball.

[0035] Specifically, the first housing 101 and the second housing 102 are threaded together. The inner wall of the first housing 101 is provided with internal threads, and the outer wall of the second housing 102 is provided with external threads. By providing a threaded connection between the first housing 101 and the second housing 102, the first housing 101 and the second housing 102 can be fixed by their own structures, reducing the difficulty of connecting and disassembling the first housing 101 and the second housing 102, and simplifying the structure of the outer shell 1.

[0036] Specifically, the outer surface of the inner shell 2 is provided with a clearance groove 205, and a third clearance hole penetrates through the bottom of the clearance groove 205, with the third clearance hole spaced apart from the groove wall of the clearance groove 205. By providing the clearance groove 205, a clearance area can be formed near the charging port 6, allowing the charging cable to be smoothly inserted into the charging port 6 and avoiding positional interference between the charging cable and the inner shell 2.

[0037] Specifically, it includes a light-emitting element 8, which is electrically connected to a control circuit 7. A fourth clearance hole is provided on the inner shell 2, into which the light-emitting element 8 extends. The first shell 101 is a light-transmitting shell, allowing light emitted by the light-emitting element 8 to pass through it. In this embodiment, the light-emitting element 8 is an LED light. By providing the light-emitting element 8, the pet's attention can be attracted through changing light patterns, increasing their interest in playing.

[0038] Specifically, the inner shell 2 includes a third shell 201 and a fourth shell 202. The third shell 201 has a fixing hole, and the fourth shell 202 has a screw hole. A screw 9 passes through the fixing hole and is screwed into the screw hole. By providing a detachable connection between the third shell 201 and the fourth shell 202, it is easy to disassemble and repair when the motor 3, battery 4, or control circuit 7 malfunctions. The third shell 201 and the fourth shell 202 are connected by threads, which can improve the connection strength between the two.

[0039] Specifically, the driving component includes a counterweight 5, which is fixed inside the inner shell 2. By setting the counterweight 5, the weight inside the inner shell 2 can be made uneven. When the motor 3 starts, the electric ball cannot roll in a straight line, causing it to deviate from the intended direction of travel. The direction of deviation is random, which enhances the fun of playing.

[0040] Specifically, the inner wall of the inner shell 2 has at least two protruding first ribs 206, and the counterweight 5 is fastened between two adjacent first ribs 206. By setting the first ribs 206 to fix the counterweight 5, the counterweight 5 can be prevented from shaking inside the inner shell 2, thereby preventing collision between the counterweight 5 and the motor 3 when the electric ball rotates.

[0041] Specifically, the inner wall of the inner shell 2 is also provided with a number of second protrusions 207, which are used to fix the motor 3, the battery 4 and the control circuit 7.
