Description

Technical Field

[0001] The utility model relates to the technical field of steering gears, in particular to an assembled steering gear structure. Background Art

[0002] Servos play an important role in fighting robots. They are the key components to realize the joint movement of robots. The working principle of servos is to add angle sensors and control circuits to control the rotation of motors on the basis of ordinary motors and reduction gearboxes, so that the rotation angle of the robot can be accurately controlled by receiving pulse signals. As an important moving component in fighting robots, the performance of servos is directly related to the operating performance and competition results of robots.

[0003] At present, servos generally adopt conventional tower transmission structure. Although the design is simple, its impact resistance is relatively weak when facing strong impact or vibration, which makes the structure easy to be damaged. This design has certain shortcomings in stability and durability. Especially in harsh operating environments, the probability of damage to the servo will increase, thereby affecting its normal operation and service life. Utility Model Content

[0009] Preferably, a connector is fixedly mounted on the servo body, and the connector is electrically connected to the PCB board.

[0010] Preferably, a card slot is provided on the steering gear body.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model effectively improves the impact resistance of the assembled steering gear structure by installing a planetary gear set. The motor works through the cooperation of the driving gear and the driven gear, which will drive the planetary gear set to move. When the planetary gear set moves, the speed transmitted by the motor will be reduced, and the torque will be increased to rotate the output shaft, which will drive the steering wheel to move. The steering wheel is used to control the joint movement of the fighting robot. The primary gear of the assembled steering gear structure uses synchronous gear transmission, and the output stage uses a planetary structure, which increases the impact resistance, improves the service life and transmission efficiency, and the output shaft of the steering gear passes through the PCB board, so that the PCB board, potentiometer, and motor can be placed on the same side of the steering gear, which is more compact.

[0013] 2. The utility model facilitates improving the assembly efficiency of the assembled steering gear structure by providing a card slot. After the steering gear body is placed at the installation location, a positioning bolt is used to pass through the fixed location and is threadedly connected to the threaded barrel, so that the position of the steering gear body can be fixed and installed. After two groups of symmetrically arranged C-shaped groove structures are respectively engaged with one side of the card slot for connection, the C-shaped groove structure is pushed to slide and close, so that the position of the steering gear body can be fixed without using bolts for fixing. Thus, the installation efficiency is improved through two different fixing methods. BRIEF DESCRIPTION OF THE DRAWINGS
