Reflector and chuck assembly thereof

A chuck assembly for a reflector, comprising:

• a chassis configured to bear a plurality of ribs articulated with the chassis;
• a slip ring fixedly arranged on the chassis, the slip ring comprising an annular sidewall and at least one guide rail arranged on the annular sidewall, and each guide rail extending circumferentially along the annular sidewall;
• and
• a top plate rotatably sleeved on the slip ring, the top plate being fixedly provided with a guide shaft facing the slip ring, and the guide shaft being movably arranged on the at least one guide rail;
• wherein the top plate rotates circumferentially along the slip ring, the guide shaft moves along the at least one guide rail, and the top plate lifts axially along the slip ring;
• and the top plate moves up and down to hold down an articulated end of the plurality of ribs to rotate;
• wherein a platen and a needle roller plate are further arranged between the chassis and the top plate, the platen being configured to hold down the articulated end of the plurality of ribs, the needle roller plate being held down between the platen and the top plate, the needle roller plate comprising a plate body and a plurality of needle rollers rotatably disposed on the plate body, the plurality of needle rollers being distributed radically along the plate body, the plurality of needle rollers rotating around self-axes, and the plurality of needle rollers being in linear contact with the top plate and the platen.

A reflector comprising a plurality of ribs, a reflective fabric and a chuck assembly, wherein the chuck assembly comprises:

• a chassis configured to bear the plurality of ribs articulated with the chassis;
• a slip ring fixedly arranged on the chassis, the slip ring comprising an annular sidewall and at least one guide rail arranged on the annular sidewall, and each guide rail extending circumferentially along the annular sidewall;
• and
• a top plate rotatably sleeved on the slip ring, the top plate being fixedly provided with a guide shaft facing the slip ring, and the guide shaft being movably arranged on the at least one guide rail;
• wherein the top plate rotates circumferentially along the slip ring, the guide shaft moves along the at least one guide rail, and the top plate lifts axially along the slip ring;
• and the top plate moves up and down to hold down an articulated end of each rib to rotate;
• wherein the at least one guide rail is a guide slot, a shaft sleeve is rotatably sleeved on the guide shaft, the guide shaft is assembled into the guide slot via the shaft sleeve, and the shaft sleeve rolls along the guide slot;
• wherein the reflective fabric is detachably arranged on each rib, and the articulated end of each rib is articulated on the chassis.
