Patent number: 10088873Abstract: A chassis structure is disclosed. A chassis includes a plate-like body in which a foam layer is located between a pair of fiber-reinforced resin plates, and a frame body formed of a thermoplastic resin and joined to a peripheral portion of the plate-like body. The plate-like body is configured such that its peripheral portion is formed by an ear-like joint portion where the pair of fiber-reinforced resin plates are joined together without the foam layer located therebetween, thereby sealing the foam layer inside the pair of fiber-reinforced resin plates. The frame body is joined to the plate-like body in a state where the frame body is in contact with the joint portion.Type: GrantFiled: September 12, 2017Date of Patent: October 2, 2018Assignee: LENOVO (SINGAPORE) PTD LTEInventors: Fumitake Mizoguchi, Ryota Nohara, Takehito Yamauchi, Ryo Otsuka

Patent number: 9977463Abstract: An electronic device having a member for chassis is disclosed. The member for chassis includes a surface layer, a rear layer disposed inside of the surface layer in a thickness direction, and an intermediate layer disposed between the surface layer and the rear layer. Each of the surface layer and the rear layer includes a fiber-reinforced resin plate. The intermediate layer is made of a material that is compressible in the thickness direction. The member for chassis further includes a fastening hole that penetrates through the surface layer, the intermediate layer and the rear layer, through which a fastener passes to fix the member for chassis to a member for attachment. The surface layer includes a cut line having a larger diameter than the fastening hole in order to surround the fastening hole.Type: GrantFiled: August 26, 2016Date of Patent: May 22, 2018Assignee: LENOVO (SINGAPORE) PTD LTEInventors: Masayuki Amano, Seita Horikoshi, Ryota Nohara, Takehito Yamauchi

Patent number: 9910456Abstract: An information processing device is disclosed. The information processing device includes a first chassis and a second chassis that are connected rotatably via a hinge, and includes a connector to connect the first chassis to the hinge. The first chassis includes a laminated part having a lamination of a set of fiber-reinforced plastic layers in each of which resin is reinforced by fibers arranged in a predetermined direction. The connector is attached and fixed to a recess in the laminated part, with the recess having a shape corresponding an outer shape of the connector. Directly attached to the connector, one of the fiber-reinforced plastic layers making up a bottom of the recess and is a layer in which fibers are arranged in a direction orthogonal to a rotary axis of the hinge.Type: GrantFiled: August 19, 2016Date of Patent: March 6, 2018Assignee: LENOVO (SINGAPORE) PTE LTDInventors: Ryota Nohara, Takehito Yamauchi, Takane Fujino, Yoshiyuki Shibayama
