Patent number: 9041558Abstract: A parking sensor device has a casing, a front cover, a sensor module and an assembling clamp. The casing has two first hooking elements. The front cover is mounted on the casing. The sensor module is mounted in the casing and the front cover. The assembling clamp detachably engages the casing and has two second hooking elements. The second hooking elements selectively hook the first hooking elements of the casing respectively. The casing and the assembling clamp are engaged quickly with each other, thereby facilitating the easy fabrication of the parking sensor device and improving the convenience of maintenance of the parking sensor device.Type: GrantFiled: November 6, 2013Date of Patent: May 26, 2015Assignee: Tung Thih Electronic Co., Ltd.Inventors: Chiun-Hua Chang, Yih-Jyh Lin
