Patent number: 12179626Abstract: A structure for holding a battery on an automated guided vehicle (AGV) so as to allow easy and convenient battery replacement includes two fixed supports and a bracket. The bracket is connected between the two supports and each support defines a vertical groove and two horizontal grooves. Two sliders at the ends of the bracket are insertable into either horizontal groove. The two sliders can move down along the vertical groove together until the bracket makes contact with the battery and holds it in place. The two sliders can move up along the vertical groove and sideways into the horizontal grooves, thereby unlatching and releasing the battery for rapid replacement. An AGV using the structure is also disclosed.Type: GrantFiled: September 21, 2022Date of Patent: December 31, 2024Assignees: Futaijing Precision Electronics (Yantai) Co., Ltd., HON HAI PRECISION INDUSTRY CO., LTD.Inventors: Hun-Yi Chou, Chih-Cheng Lee, Yu-Sheng Chang, Yu-Cheng Zhang, Hsiu-Fu Li, Chang-Ju Hsieh, Tsung-Hsin Wu, Chiung-Hsiang Wu, Chen Chao, Chen-Ting Kao, Chi-Cheng Wen, Sheng-Li Yen

Publication number: 20230331526Abstract: A locking mechanism comprises a main body, an ejector rod, a guide rod assembly, a carrier plate and a fixing assembly. The carrier plate comprises a center hole and a plurality of annular strip holes. The fixing assembly comprises a rotary disc. The center hole and the annular strip holes can lock the rotary disc in different rotation angles. The guide rod assembly limits the rotation tolerance of the carrier plate, and makes the carrier plate move up and down in the vertical direction. The rotary disc with limited rotational freedom is fixedly connected with the ejector rod, so that the locking mechanism can not only realize the linear lifting motion of the ejector rod, but also reduce the rotation angle error between the carrier plate and the ejector rod. A rotating lifting platform is also provided.Type: ApplicationFiled: February 24, 2023Publication date: October 19, 2023Inventors: CHI-CHENG WEN, YU-SHENG CHANG, CHIH-CHENG LEE, CHIUNG-HSIANG WU, CHANG-JU HSIEH, YU-CHENG ZHANG, SHENG-LI YEN, CHEN CHAO, CHEN-TING KAO
