Description

Technical Field

[0001] The utility model relates to the technical field of building block steering gears, in particular to a single-axis power output device capable of splicing building blocks. Background Art

[0002] The servo is composed of a circuit board, a motor, a reduction gear set, a sensor and a control circuit. Its working principle is that the robot's main control board sends a control signal to the servo, which is processed by the IC on the servo circuit board to determine the direction of rotation, and then drive the coreless motor to start rotating. The power is transmitted to the swing arm through the reduction gear set, and the position detection sensor sends back a detection signal to determine whether the predetermined position has been reached. The servo is the power source for remote control models and humanoid robots to control actions, and it is also an important motion execution device that drives the robot's joint activities. As an executive component, the transmission components inside the servo are very important, and most traditional building block servos are directly assembled in the shell, which makes it easy for the transmission components of the building block servo to be dislocated when hit, and then the transmission components cannot work normally. The steering wheel and output shaft of the building block servo are simply spliced, which makes it easy for the steering wheel to fall and be lost. Utility Model Content

The clamping portion 132 includes a clamping rod and a clamping hook head. The clamping hook head is arranged on the top of the clamping rod. And the opposite surfaces of the upper cover 11 and the lower cover 12 have guiding inclined surfaces 124 corresponding to the clamping grooves 123. Therefore, the clamping portion 132 undergoes elastic deformation under the action of the guiding inclined surface, making it easier for the clamping portion 132 to be buckled into the clamping grooves 123 of the upper cover 11 and the lower cover 12. Without any mechanical connection, the number of components is greatly reduced.

[0024] Further, a shaft hole 111 is arranged inside the upper cover 11 and is rotationally matched with the output shaft 2. A transmission assembly 5 is arranged in the concave cavity 131 and is in transmission connection with the output shaft 2 and the driving device 3. The driving device 3 drives the transmission assembly 5 to drive the output shaft 2 to rotate.

[0025] More preferably, a support panel 14 is arranged between the housing body 13 and the upper cover 11. A number of mounting holes are respectively arranged opposite to each other between the concave cavity 131 and the support panel 14. A number of gears are respectively rotatably arranged between the mounting holes, so that the transmission assembly 5 is restricted between the concave cavity 131 and the support panel 14, and the number of gears mesh with each other. A number of support portions 1311 are equidistantly arranged on the inner wall of the concave cavity 131, so that the peripheral wall of the support panel 14 abuts against the top of the support portions 1311. And a positioning shaft 1312 is arranged on the peripheral wall of the support portion 1311. A positioning hole 141 that is matched with the positioning shaft is formed on the support panel 14. And a step groove 112 is arranged on the inner wall of the upper cover 11. A butting surface 142 that is matched with the step groove 112 protrudes from the edge of the support panel 14. Further, after the upper cover 11 and the housing body 13 are buckled, the support panel 14 on the concave cavity 131 is pressed tightly by the upper cover 21, thereby preventing the number of gears from being displaced in the concave cavity and making the transmission of the building block servo more stable.

[0026] A receiving cavity is recessed inward on the bottom surface of the housing body 13. A through hole communicating with the concave cavity is provided on the receiving cavity. The driving device 3 is placed in the receiving cavity of the housing body 13. In this embodiment, the driving device 3 preferably adopts a micro motor, and its output shaft passes through the through hole and is fixedly provided with a driving gear. The driving gear meshes with one of the gears of the transmission assembly 5. A toothed ring 31 meshing with one of the gears of the transmission assembly 5 is provided at the lower part of the output shaft 2. And a cross slot is provided on the top surface of the output shaft, which can be used for splicing with traditional building blocks. Thus, the driving device 3 is used to drive a number of gears to drive the output shaft 2 to rotate, so as to provide power for the traditional building blocks through the output shaft 2.

[0027] Further, an electronic cavity 121 is provided inside the lower cover 12. The control unit 4 is arranged in the electronic cavity 121.

Wherein, a slot 122 matching the signal connector 42 is provided on the peripheral wall of the lower cover 12. A pressing block 133 matching the shape of the slot 122 is provided at the bottom edge of the housing body 13. Thus, by placing the signal connector 42 in the slot 122, after the lower cover and the housing body are buckled, the signal connector in the slot 122 is pressed by the pressing block, so as to fix the circuit board 41 in the electronic cavity 121. The circuit board 41 is electrically connected to the driving device 3, and the position feedback module is electrically connected to the circuit board 41. In this embodiment, the position feedback module preferably adopts an angle potentiometer. A shaft rod is provided at the bottom of the output shaft 2. A round hole penetrating the bottom surface is provided in the concave cavity 131 of the housing body 13. The shaft rod of the output shaft 2 passes through the round hole and is connected to the position feedback module. When the driving device 3 drives the output shaft 2 to rotate, the position feedback module detects and feeds back the rotation angle and speed of the output shaft 2 to the circuit board 41, so as to realize precise control of the rotation angle and speed of the output shaft. And in this embodiment, one of the signal connectors 42 is connected to an external control device for transmitting signals to the control module, and the other signal connector 42 is connected to an external power supply, so as to supply power to the control module through the external power supply.
