Description

Technical Field

[0001] This utility model relates to the field of mechanical toy technology, and more specifically, to a toy mechanical dog. Background Technology

[0002] A toy robotic dog is an intelligent electronic toy that mimics the appearance, movements, and even interactive behaviors of a real dog, based on bionics and robotics. It combines mechanical structures, sensors, program control, and artificial intelligence technologies to achieve functions such as autonomous movement, voice interaction, and action performance.

[0003] For example, application number CN201120110326.1 discloses a mechanical toy dog. By designing a mechanical toy dog ​​driven by piezoelectricity, the existing mechanical toy dog ​​structure is redesigned. The use of piezoelectricity for transmission simplifies the entire structure, greatly improves the toy's lifespan, and makes the toy lightweight. Furthermore, the leg and paw mechanism of this patent can perform various movements, thus imitating various dog actions, greatly improving the toy's playability and giving it a very high market prospect. In the prior art, when controlling the movement of the mechanical dog's legs, the angle of leg movement cannot be monitored. It can only perform reciprocating movements based on an initially set angle, and real-time monitoring is not possible. Moreover, after long-term use, the angle of movement of the mechanical dog's legs is easily changed due to wear or other external forces.

[0004] Therefore, a toy mechanical dog is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a toy mechanical dog to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a toy mechanical dog, comprising a shell body, a first drive mechanism, a second drive mechanism, a circuit board, and mechanical legs. The inner cavity of the shell body is provided with the first drive mechanism and the second drive mechanism, and both the first and second drive mechanisms are provided in two sets. Both the first and second drive mechanisms are electrically connected to the circuit board. Mechanical legs are provided at the output ends of the first and second drive mechanisms. The second drive mechanism includes a drive housing and a micro servo motor. A micro servo motor is provided on one side of the drive housing, and a gear set is provided inside the drive housing. A detection mechanism is provided on the side end face of the moving housing. The gear set is installed at the output end of the micro servo motor, and a protection mechanism is installed in the gear set. The gear set is connected to a first output wheel through the protection mechanism. The first output wheel is installed on the outer diameter surface of the output shaft, and a second output wheel is provided on the outer diameter surface of the output shaft. The detection mechanism includes a detection wheel and a positioning frame. The detection wheel is installed at the tangent of the second output wheel and is meshed with the second output wheel. The detection wheel is installed on the side end face of the driving housing through the positioning frame. A micro angle sensor is connected to the detection wheel through the positioning frame. The first driving mechanism and the second driving mechanism have the same structure.

[0007] Preferably, the protection mechanism includes a limiting shaft and a return spring. The return spring is fitted onto the outer diameter surface of the limiting shaft, and a first protective gear is provided on the outer diameter surface of the limiting shaft. A limiting groove is provided on the upper end surface of the first protective gear, and a second protective gear is provided above the first protective gear. A limiting protrusion is provided on the lower end surface of the second protective gear.

[0008] Preferably, the two sets of the first drive mechanism and the two sets of the second drive mechanism are respectively mounted on both sides of the circuit board, and the two sets of the first drive mechanism and the two sets of the second drive mechanism are arranged symmetrically.

[0009] Preferably, the micro servo motors in the two sets of the first drive mechanism and the two sets of the second drive mechanism are electrically connected to the circuit board, and the circuit board is electrically connected to LED lights.

[0010] Preferably, the micro servo motor forms a gear meshing structure with the detection wheel and output shaft in the detection mechanism through a gear set, a protection mechanism, a first output wheel and a second output wheel.

[0011] Preferably, the miniature angle sensor in the detection mechanism is electrically connected to the circuit board, and the first protective gear in the protection mechanism and the limiting shaft in the protection mechanism form a sliding structure.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] Compared with existing technologies, this toy mechanical dog has two sets of first drive mechanisms and two sets of second drive mechanisms, which control the movement of four mechanical legs. Each of the two sets of first drive mechanisms and two sets of second drive mechanisms is equipped with a detection wheel, a positioning frame and a miniature angle sensor, which can detect the final angle of the movement of the four mechanical legs at all times. This can prevent the final angle of the movement of the mechanical dog's legs from changing due to wear or other external forces after long-term use.

[0014] Compared with existing technologies, this toy mechanical dog, when in use, has two sets of first and second drive mechanisms respectively arranged in the shell body. These mechanisms drive the mechanical legs to move, and are controlled by a circuit board. A miniature servo motor in the drive shell drives a first output wheel, an output shaft, and a second output wheel to rotate via a gear set, a detection mechanism, and a protection mechanism, thereby driving the mechanical legs. Furthermore, a detection wheel, a positioning frame, and a miniature angle sensor continuously monitor the final angle of the mechanical legs' movement, preventing changes in the final angle of the dog's legs due to wear or other external forces over prolonged use. The angle detected by the miniature angle sensor... The system provides real-time feedback to the circuit board to ensure that the final angle of each mechanical leg movement is the same, eliminating the need to consider gear wear and other external forces. It also incorporates a protective mechanism to prevent damage to the transmission structure from foreign objects. The first and second protective gears rotate synchronously, with the first protective gear engaging with the second protective gear via a limiting groove and a limiting protrusion. Both the first and second protective gears are mounted on the outer diameter surface of the limiting shaft, forming a sliding structure. Simultaneously, the first protective gear reciprocates with the limiting shaft via a return spring. Therefore, when excessive torque occurs, the first and second protective gears separate, discontinuing gear transmission and achieving a protective effect. Attached Figure Description

The shell body 1 has the first drive mechanism 2 and the second drive mechanism 3 housed within its inner cavity, and both the first drive mechanism 2 and the second drive mechanism 3 are provided in two sets. Both the first drive mechanism 2 and the second drive mechanism 3 are electrically connected to the circuit board 4. Mechanical legs 5 are located at the output ends of the first drive mechanism 2 and the second drive mechanism 3. The second drive mechanism 3 includes a drive housing 31 and a micro servo motor 32. The micro servo motor 32 is located on one side of the drive housing 31, and a gear set 33 is located within the inner cavity of the drive housing 31. Furthermore, the side end face of the drive housing 31 is... The system includes a detection mechanism 34, a gear set 33 mounted on the output end of a micro servo motor 32, and a protection mechanism 35 installed in the gear set 33. The gear set 33 is connected to a first output wheel 36 via the protection mechanism 35, and the first output wheel 36 is mounted on the outer diameter surface of an output shaft 37. A second output wheel 38 is also mounted on the outer diameter surface of the output shaft 37. The detection mechanism 34 includes a detection wheel 341 and a positioning frame 342. The detection wheel 341 is mounted at the tangent of the second output wheel 38 and meshes with the second output wheel 38. The detection wheel 341 is mounted on the side end face of the drive housing 31 via the positioning frame 342. The detection wheel 341 is connected to the micro servo motor 32 via the positioning frame 342. The angle sensor 343, the first drive mechanism 2, and the second drive mechanism 3 have the same structure. Each set of the first drive mechanism 2 and the second drive mechanism 3 is equipped with two sets of the first drive mechanism 2 and two sets of the second drive mechanism 3, respectively controlling the movement of the four mechanical legs 5. Each set of the first drive mechanism 2 and the second drive mechanism 3 is equipped with a detection wheel 341, a positioning frame 342, and a miniature angle sensor 343 from the detection mechanism 34, capable of constantly detecting the final angle of the movement of the four mechanical legs 5. The housing body 1 contains two sets of the first drive mechanism 2 and the second drive mechanism 3, respectively, to drive the movement of the mechanical legs 5, and the movement is controlled by the circuit board 4. The micro servo motor 32 in the drive housing 31 drives the first output wheel 36, output shaft 37 and second output wheel 38 to rotate through the gear set 33, detection mechanism 34 and protection mechanism 35, thereby driving the mechanical leg 5 to move. The final angle of the mechanical leg 5 is detected in real time by the detection wheel 341, positioning frame 342 and micro angle sensor 343 to avoid the final angle of the mechanical dog leg changing due to wear or other external forces due to long-term use. The angle detected by the micro angle sensor 343 is fed back to the circuit board 4 in real time to ensure that the final angle of the mechanical leg 5 is the same every time, without having to consider gear wear and other external forces.

The return spring 352 is fitted onto the outer diameter surface of the limiting shaft 351, and a first protective gear 353 is provided on the outer diameter surface of the limiting shaft 351. A limiting groove 354 is provided on the upper end surface of the first protective gear 353, and a second protective gear 355 is provided above the first protective gear 353. A limiting protrusion 356 is provided on the lower end surface of the second protective gear 355, and the protection mechanism 35 is installed therein, thereby preventing damage to the transmission structure due to foreign objects. The first protective gear 353 rotates synchronously with the second protective gear 355. The first protective gear 353 is engaged with the second protective gear 355 through the limiting groove 354 and the limiting protrusion 356. Both the first protective gear 353 and the second protective gear 355 are mounted on the outer diameter surface of the limiting shaft 351, and the first protective gear 353 and the limiting shaft 351 form a sliding structure. At the same time, the first protective gear 353 and the limiting shaft 351 form a reciprocating motion through the return spring 352. When the torque is too large, the first protective gear 353 and the second protective gear 355 separate so as not to continue gear transmission, thereby achieving the protection effect.

[0028] In a preferred embodiment, two sets of first drive mechanisms 2 and two sets of second drive mechanisms 3 are respectively installed on both sides of the circuit board 4, and the two sets of first drive mechanisms 2 and two sets of second drive mechanisms 3 are arranged symmetrically.

[0029] In a preferred embodiment, the micro servo motors 32 in the two sets of first drive mechanisms 2 and the two sets of second drive mechanisms 3 are electrically connected to the circuit board 4, and the circuit board 4 is electrically connected to LED lights 6, thereby mimicking the effect of eyes emitting light.

[0030] In a preferred embodiment, the micro servo motor 32 forms a gear meshing structure with the detection wheel 341 and output shaft 37 in the detection mechanism 34 through the gear set 33, the protection mechanism 35, the first output wheel 36 and the second output wheel 38.

[0031] In a preferred embodiment, the miniature angle sensor 343 in the detection mechanism 34 is electrically connected to the circuit board 4, and the first protective gear 353 in the protection mechanism 35 and the limiting shaft 351 in the protection mechanism 35 form a sliding structure.

[0032] The working process of this utility model is as follows: First, two sets of first drive mechanisms 2 and two sets of second drive mechanisms 3 are respectively set to control the movement of four sets of mechanical legs 5. Each of the two sets of first drive mechanisms 2 and two sets of second drive mechanisms 3 is equipped with a detection wheel 341, a positioning frame 342, and a miniature angle sensor 343 in a detection mechanism 34, which can detect the final angle of the movement of the four sets of mechanical legs 5 at all times. Two sets of first drive mechanisms 2 and two sets of second drive mechanisms 3 are respectively set in the housing body 1. The mechanical legs 5 are driven by the first drive mechanisms 2 and the second drive mechanisms 3, and controlled by the circuit board 4. The miniature servo motor 32 in the drive housing 31 drives the first output wheel 36, the output shaft 37, and the second output wheel 38 to rotate through the gear set 33, the detection mechanism 34, and the protection mechanism 35, thus driving the movement of the mechanical legs 5. The detection wheel 341, the positioning frame 342, and the miniature angle sensor 343 are used to detect the final angle of the movement of the mechanical legs 5 in real time, preventing damage due to prolonged use. In operation, the final angle of the mechanical dog leg 5's movement is altered by wear or other external forces. The angle detected by the miniature angle sensor 343 is fed back to the circuit board 4 in real time to ensure that the final angle of the mechanical leg 5's movement is the same each time. There is no need to consider gear wear or other external forces. A protective mechanism 35 is installed to prevent damage to the transmission structure caused by foreign objects. The first protective gear 353 and the second protective gear 355 rotate synchronously. The first protective gear 353 is engaged with the second protective gear 355 using a limiting groove 354 and a limiting protrusion 356. Both the first protective gear 353 and the second protective gear 355 are mounted on the outer diameter surface of the limiting shaft 351, and the first protective gear 353 and the limiting shaft 351 form a sliding structure. At the same time, the first protective gear 353 uses a return spring 352 to reciprocate with the limiting shaft 351. When the torque is too large, the first protective gear 353 and the second protective gear 355 separate, thus stopping the gear transmission and achieving the protection effect.
