[0002] Due to the limitation of the use environment, the width direction (Y direction) of the small side armrest of the car seat is generally not very large, resulting in a relatively small internal space of the armrest, and conventional cup holders cannot be set, which cannot meet the customer's demand for arranging cup holders on the small armrest. For this reason, China Utility Model Patent Authorization Announcement No. CN217320160U discloses a side armrest cup holder mechanism, including a cup holder, a placement slot is provided on the cup holder, two rotating shafts and two pins are provided on the cup holder, each rotating shaft is connected to a clamping arm, and an extension rod is provided at one end of the clamping arm away from the placement slot, and the extension rod is connected to the pin through an elastic reset structure. The gripper opening and closing mechanism for the automobile cup holder has an elastic reset structure between the extension rod of the clamping arm and the pin shaft. When the cup is placed in the placement slot, the two clamping arms are pushed outward by the downward pressure, and the elastic reset structure is deformed and in a compressed state. After the cup is placed in place, the elastic reset structure is opened and reset while pushing the extension rod outward, so that the two clamping arms clamp the cup. The mechanism can not only adapt to cups of different sizes, but also enable the cup to be taken out and placed in the event of a power outage or fault.
