Title:
POWER BOX AND CONTROL ARM
Document Type and Number:
WIPO Patent Application WO/2024/093422
Kind Code:
A1
Abstract:
The present disclosure relates to a power box and a control arm. The power box comprises a fixing plate and a plurality of electric motors, wherein the body of each electric motor is arranged on the fixing plate, and an output shaft extends out of the fixing plate. The power box further comprises a controller and a plurality of encoders, wherein the encoders correspond to the electric motors on a one-to-one basis, and each encoder comprises an annular grating disk and a reading head, the grating disk being sleeved on an output shaft, and having a plurality of circles of scale lines on the surface facing the fixing plate, the plurality of circles of scale lines being concentric, two adjacent circles of scale lines in the circumferential direction being arranged in a pairwise staggered manner, and the reading head being arranged on the fixing plate and located directly below the scale lines; and the controller is arranged on the fixing plate, the controller is in communication connection to the electric motor and reading heads, and the controller is configured to control the rotation of the electric motor according to scale information, which is information that corresponds to the scale lines and is collected by the reading heads. Accumulated errors and precision loss are reduced, such that the precision is improved, and rapid fault recovery can be achieved, thereby shortening the operation time.
