Patent number: 10660304Abstract: The invention is a pet feeding device provides a feeding mechanism on a basis of fixed time and fixed amount of food for a pet. The pet feeding device includes a base and a rotatable tray. The base has a first opening and a second opening communicated with each other, and the second opening connects the base and an exterior environment. The rotatable tray having third openings is assembled to the base and rotates about an axis. The feed pellets received in the pet feeding device fall into the third openings with a rotation of the rotatable tray. In a process of rotation, the first opening covers portion of the third openings correspondingly in a unit time, and the feed pellets in the corresponding third openings drop out of the pet feeding device via the first opening and the second opening.Type: GrantFiled: October 2, 2017Date of Patent: May 26, 2020Assignee: Acer IncorporatedInventors: Yu-Cheng Huang, Shao-Chi Chuang, Tsung-Hsun Wu, Yao-Kai Chuang, Wei-Chen Lai

Patent number: 10525864Abstract: A transportation device includes a motor, a transmission assembly, a position limiting assembly, two linkage assemblies, and two wheels. The transmission assembly is linked to the motor. The position limiting assembly includes two position limiting board portions disposed in parallel and adjacent to each other. The two linkage assemblies partially extend into a space between the two position limiting board portions and are pivoted to the two position limiting board portions, respectively. The two linkage assemblies are limited by the two position limiting board portions in a first axis. The two wheels are disposed in tandem along a second axis, respectively linked to the transmission assembly, and pivoted to the two linkage assemblies. The two wheels are driven by the motor respectively through the transmission assembly and are limited by the two linkage assemblies in the first axis. A transportation system including the transportation device is also provided.Type: GrantFiled: April 3, 2018Date of Patent: January 7, 2020Assignee: Acer IncorporatedInventors: Wen-Pin Chang, Wen-Shu Lee, Pu-De Ciou, Wei-Chen Lai, Chun-Hung Wen, Tsung-Hsun Wu
