Patent number: 12244053Abstract: The present disclosure relates to an antenna RF module, an RF module assembly including the antenna RF modules, and an antenna apparatus including the RF module assembly. Particularly, the antenna RF module includes an RF module, a radiation element module arranged on a first side of the RF filter, and an amplification unit board arranged on a second side of the RF filter, an analog amplification element being mounted on the amplification unit board. A plurality of antenna RF modules constitute the RF module assembly, and the RF module assembly and an antenna housing constitute the antenna apparatus. Accordingly, a radome that interrupts dissipation of heat to in front of an antenna is unnecessary, and heat generated from heat generating elements of the antenna apparatus is spatially separated. Thus, it is possible that the heat is dissipated in a distributed manner toward the front and rear directions of the antenna apparatus. The effect of greatly improving performance in heat dissipation can be achieved.Type: GrantFiled: April 16, 2023Date of Patent: March 4, 2025Assignee: KMW INC.Inventors: Duk Yong Kim, Young Chan Moon, Nam Shin Park, Sung Ho Jang, Jae Hong Kim, Joon Hyong Shim, Bae Mook Jeong, Min Seon Yun, Sung Hwan So, Yong Won Seo, Oh Seog Choi, Kyo Sung Ji, Chi Back Ryu, Seong Min Ahn, Jae Eun Kim

Publication number: 20240125365Abstract: A pad liner includes a first pad clip that surrounds and is coupled to a side protrusion protruding in a lateral direction from a brake pad, and a torque support located under the first pad clip and between a side surface of the brake pad and the caliper body. The torque support supports a braking torque. The first pad clip includes a reference surface located on one of a top surface and a bottom surface of the side protrusion, a vertical elastic portion located on an opposite side from the reference surface that pressurizes the side protrusion in a direction of the reference surface, and a clip side portion that connects the reference surface and the vertical elastic portion and surrounds a side surface of the side protrusion. The pad liner minimizes a vertical gap and movement of the brake pad.Type: ApplicationFiled: October 16, 2023Publication date: April 18, 2024Applicant: HYUNDAI MOBIS CO., LTD.Inventors: Kang Kuk LEE, Seong Hwan AHN, Wan Kyu LEE, In Ho LEE, Yeong Bin CHO
