[0020] The following are the beneficial effects of implementing this utility model:
[0021] This utility model relates to a toy robot. When the toy robot's moving mechanism is in operation, a first motor outputs torque, which is transmitted to a movable seat via a first drive shaft. This drives the movable seat (along with a second motor and a second drive shaft mounted thereon) to rotate around the central axis of the first drive shaft. This rotation directly drives the arm, which is connected to the second drive shaft, to perform inward or outward opening and closing movements in the horizontal plane; that is, the arm can rotate towards or away from the torso.
[0022] Meanwhile, since the second motor is mounted on the movable base, its output torque is transmitted through the second drive shaft, directly driving the arm to rotate around the central axis of the second drive shaft. This rotation typically enables the arm to rotate in the opposite direction, thus allowing the arm to perform lifting or lowering movements. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0037] Figures 1 to 3 The illustration shows a toy robot 10 according to some embodiments of the present invention, which includes a torso 1, two movable mechanisms 2, and two arms 3. The torso 1 serves to support the two movable mechanisms 2. The two movable mechanisms 2 are symmetrically arranged on the torso 1, and the two arms 3 are drivenly connected to the two movable mechanisms 2 in a one-to-one correspondence.
[0038] Understandably, each of the moving mechanisms 2 drives an arm 3 independently, so that the two arms 3 can move relative to the torso 1 respectively.
[0039] like Figures 3 to 7 As shown, each movable mechanism 2 includes a first motor 21 mounted on the torso 1, a first drive shaft 22 connected to the first motor 21, a movable seat 23 fixedly connected to the first drive shaft 22, a second motor 24 mounted on the movable seat 23, and a second drive shaft 25 connected to the second motor 24. The two arm parts 3 are correspondingly connected to the two second drive shafts 25.
[0040] The first motor 21 drives the first drive shaft 22 to rotate the movable seat 23, thereby causing the arm 3 to rotate around the central axis of the first drive shaft 22 via the movable seat 23; the second motor 24 drives the second drive shaft 25 to rotate the arm 3, thereby causing the arm 3 to rotate around the central axis of the second drive shaft 25.
[0041] Understandably, the first motor 21 outputs torque to drive the first drive shaft 22 to rotate. The first drive shaft 22 transmits the torque of the first motor 21, thereby causing the movable seat 23 to rotate around the central axis of the first drive shaft 22. The movable seat 23 supports the second motor 24 and the second drive shaft 25, and transmits the rotation of the first drive shaft 22 to the arm 3, causing the arm 3 to rotate around the central axis of the first drive shaft 22.
[0042] The second motor 24 is used to output torque to drive the second drive shaft 25 to rotate. The second drive shaft 25 is used to transmit the torque of the second motor 24, thereby directly driving the arm 3 to rotate around the central axis of the second drive shaft 25.
[0043] It should be noted that when the first motor 21 is driven: the first drive shaft 22 drives the movable seat 23 to rotate around its central axis, thereby driving the arm 3 to perform inward or outward opening and closing movements in the horizontal plane, that is, the arm 3 can rotate in the direction of approaching or moving away from the torso.
[0044] When the second motor 24 is driven: the second drive shaft 25 directly drives the arm 3 to rotate around its central axis, thereby realizing the lifting or lowering movement of the arm 3.
[0045] In summary, through the independent driving of the first motor 21 and the second motor 24 in the motion mechanism 2, and the transmission cooperation between the first drive shaft 22 and the second drive shaft 25, the arm 3 can perform compound movements around the central axes of the two drive shafts (the first drive shaft 22 and the second drive shaft 25), significantly expanding the degree of freedom of movement of the arm 3. The superposition of the two degrees of freedom of movement makes the arm 3 of the toy robot 10 move more flexibly.
[0046] It should also be noted that a power supply can be installed on the toy robot 10 to supply power to the first motor 21, the second motor 24, and other electrical components.
[0047] Furthermore, in some embodiments, the toy robot 10 may also include an audio-visual mechanism 7, which includes a speaker 71 and a light 72, with the speaker and light 72 respectively disposed on the torso. In this way, sound and light functions, in addition to motion functions, can be added to the product.
[0048] like Figure 3 As shown, in some embodiments of the toy robot 10, the central axis L1 of the first drive shaft 22 intersects the central axis L2 of the second drive shaft 25 at a right angle.
[0049] Understandably, the limitations of this embodiment allow the two movable surfaces of the arm to be perpendicular to each other, thus avoiding motion interference.
[0050] like Figures 3 to 6 As shown, in some embodiments of the toy robot 10, each active mechanism 2 further includes a fixed base 26, on which a fixed part 261 and a fixed cavity 262 are provided. The fixed part 261 is inserted into the torso 1 and is locked inside the torso 1. The first motor 21 is disposed in the fixed cavity 262.
[0051] Understandably, the fixing part 261 is inserted into the torso 1 and locked in place, achieving a rigid connection and precise positioning between the fixing seat 26 and the torso 1. The fixing cavity 262 accommodates and fixes the first motor 21, providing motor protection and heat dissipation space to ensure the operational stability of the first motor 21.
[0052] like Figure 4 and Figure 5 As shown, in some embodiments of the toy robot 10, the movable seat 23 is provided with a connecting neck 231, the edge of the connecting neck 231 is provided with a connecting flange 232, the connecting neck 231 is inserted into the fixed seat 26, and the connecting flange 232 is movably supported against the inner sidewall of the fixed seat 26.
[0053] Understandably, the connecting neck 231 is inserted into the fixed seat 26, forming a rotatable shaft-hole fit. The connecting flange 232 movably abuts against the inner sidewall of the fixed seat 26, which on the one hand restricts the axial displacement of the movable seat 23 and prevents rotational dislocation; on the other hand, it also maintains the coaxial rotational relationship between the movable seat 23 and the fixed seat 26, reducing movement wobble.
[0054] like Figure 4 and Figure 5 As shown, in some embodiments of the toy robot 10, the end of the first drive shaft 22 is provided with a first cross portion 221, which is locked inside the movable seat 23.
[0055] Understandably, the first cross portion 221 is locked into the internal groove of the movable seat 23, which can ensure that the torque is efficiently and without slippage transmitted from the first drive shaft 22 to the movable seat 23, and can also effectively eliminate transmission backlash and improve the rotation accuracy of the arm portion 3.
[0056] like Figures 3 to 7 As shown, in some embodiments of the toy robot 10, each active mechanism 2 further includes a connecting cylinder 27. One end of the connecting cylinder 27 is provided with a fixing post 271, and the other end of the connecting cylinder 27 is provided with a limiting flange 272. The end of the connecting cylinder 27 is inserted into the active seat 23, the limiting flange 272 is movably supported against the inner side wall of the active seat 23, and the fixing post 271 is inserted into the arm 3.
[0057] Understandably, the end of the connecting cylinder 27 is inserted into the movable seat 23 and abuts against the inner wall of the movable seat 23 via the limiting flange 272, which can limit the axial displacement of the connecting cylinder 27 and prevent it from disengaging during transmission. The insertion and engagement of the fixed column 271 with the arm 3 allows torque to be transmitted to the arm 3 via the second drive shaft 25. This improves the transmission stability between the arm 3 and the movable seat 23.
[0058] like Figure 4 and Figure 5 As shown, in some embodiments of the toy robot 10, the end of the second drive shaft 25 is provided with a second cross portion 251, and the second cross portion 251 passes through a limiting flange 272 and is clamped in the connecting cylinder 27.
[0059] Understandably, the second cross portion 251, with its limiting flange 272 passing through and clamped within the connecting cylinder 27, allows torque to be transmitted seamlessly from the second drive shaft 25 to the connecting cylinder 27, improving the accuracy and response speed of the lifting and lowering motion of the arm 3. Furthermore, the second cross portion 251 is generally cross-shaped, ensuring a good connection between the second drive shaft 25 and the arm at all rotation angles, preventing gaps at certain angles, maintaining the coaxiality of the second drive shaft 25 and the connecting cylinder 27 during rotation, and avoiding rotational eccentricity.
[0060] like Figure 5 , Figure 6 , Figure 8 and Figure 9 As shown, in some embodiments of the toy robot 10, the arm 3 is provided with a mounting groove 31, the groove wall of the mounting groove 31 is provided with an alignment protrusion 311, and the bottom of the mounting groove 31 is provided with a fixing groove. The connecting cylinder 27 is provided with an alignment groove 273, and the connecting cylinder 27 is detachably inserted into the mounting groove 31. The alignment protrusion 311 is detachably inserted into the alignment groove 273 (see [link to alignment groove 273]). Figure 9 The fixing post 271 can be detachably inserted into the fixing groove.
[0061] Understandably, the contour of the mounting groove 31 matches the outer contour of the connecting cylinder 27, thereby eliminating the fitting gap between the arm 3 and the connecting cylinder 27. The connecting cylinder 27 is cylindrical in shape, and the insertion fit between the alignment protrusion 311 and the alignment groove 273 can fix the relative angle between the two in the rotation direction. The insertion fit between the fixing post 271 and the fixing groove ensures that the connecting cylinder 27 can drive the arm 3 to rotate. In addition, through the content of this embodiment, the arm 3 can be quickly disassembled and precisely positioned, improving the ease of product maintenance.
[0062] Furthermore, in some embodiments of the toy robot 10, the number of fixing posts 271 and fixing slots can both be configured to be multiple, and the fixing posts 271 and fixing slots are connected in a one-to-one plug-in fit. In this way, it can be further ensured that the connecting cylinder 27 can drive the arm 3 to rotate.
[0063] like Figure 2 and Figure 7 As shown, in some embodiments of the toy robot 10, the toy robot 10 also includes two legs 4 and two moving mechanisms 5. The two legs 4 are respectively connected to the torso 1, and the two moving mechanisms 5 are respectively disposed on the two legs 4.
[0064] like Figure 6 As shown, the moving mechanism 5 includes a moving motor 51, a moving gear set 52, and two moving wheels 53. The moving motor 51 is mounted on the leg 4, the moving gear set 52 is mounted on the leg 4, and the two moving wheels 53 are rotatably mounted on the leg 4. The moving gear set 52 drives the two moving wheels 53 to rotate relative to the leg 4.
[0065] Understandably, the movable motor 51 is used to output drive torque. The movable gear set 52 is driven and connected to the output shaft of the movable motor 51, and is used to transmit and distribute torque to the two movable wheels 53. The two movable wheels 53 are each driven by the movable gear set 52.
[0066] It should be noted that when the mobile motor 51 is energized and outputs torque, the mobile gear set 52 distributes the torque to the two mobile wheels 53, driving the two mobile wheels 53 to rotate. In this way, by controlling the difference in rotational speed of the mobile wheels 53 of the two legs 4, the toy robot 10 can move forward, backward, or turn.
[0067] like Figure 7 As shown, in some embodiments of the toy robot 10, the toy robot 10 also includes a battery cover 6, a battery slot 11 is provided on the torso 1, the battery slot 11 is used to store batteries, the batteries are electrically connected to two first motors 21 and two second motors 24, and the battery cover 6 is detachably placed on the battery slot 11.
[0068] Understandably, the inner wall contour of the battery compartment 11 can be flexibly adjusted according to the number of batteries and their external dimensions. The battery cover 6 serves to protect the batteries.
[0069] The following are the beneficial effects of implementing this utility model:
[0070] This utility model relates to a toy robot. When the toy robot's moving mechanism is in operation, a first motor outputs torque, which is transmitted to a movable seat via a first drive shaft.

This rotation directly drives the arm, which is connected to the second drive shaft, to perform inward or outward opening and closing movements in the horizontal plane; that is, the arm can rotate towards or away from the torso.
[0071] Meanwhile, since the second motor is mounted on the movable base, its output torque is transmitted through the second drive shaft, directly driving the arm to rotate around the central axis of the second drive shaft. This rotation typically enables the arm to rotate in the opposite direction, thus allowing the arm to perform lifting or lowering movements.
