  • Publication number: 20240120812
    Abstract: An integrated motor and drive assembly is disclosed and includes a housing, a motor and a drive. The housing includes a motor-accommodation portion and a drive-accommodation portion. The drive includes a power board and a control board. The power board is made of a high thermal conductivity substrate and includes a power element and an encoder disposed on the first side, the first side faces the motor, the power board and the motor are stacked along a first direction, and the second side contacts the housing to from a heat-dissipating route. The control board is disposed adjacent to the power board. The control board and the power board are arranged along a second direction perpendicular to the first direction, and the first direction is parallel to an axial direction of the motor. A part of the power board and a part of the control board are directly contacted to form an electrical connection.

  • Patent number: 11109514
    Abstract: An electronic device includes an outer case, a heat generating component and a heat dissipating module. The heat generating component is disposed inside the outer case. The heat dissipating module is located between the outer case and the heat generating component and includes a heat conducting assembly including a first heat conducting portion fixed on the outer case and connected to the outer case and a second heat conducting portion connected to the first heat conducting portion and for abutting against the heat generating component. The second heat conducting portion is movable relative to the outer case for moving toward or away from the outer case. The heat conducting assembly is resiliently deformed to apply a force on the heat generating component in a contacting manner when the heat generating component pushes the second heat conducting portion of the heat conducting assembly to move toward the outer case.

  • Patent number: 10678301
    Abstract: An assembled industrial tablet is provided. A first floating connector, which is disposed on a screen assembly, and a second floating connector, which is disposed on a tablet assembly, are assembled, and the tablet assembly is limited in an assembly space of the screen assembly through limiting structures of the screen assembly, so that the industrial tablet is assembled. Therefore, the technical efficiency of assembling the industrial tablet conveniently may be achieved.

  • Publication number: 20190039510
    Abstract: A graphic luminous device includes a lamp holder, a light source disposed at one side of the lamp holder, a light-guiding board disposed on the lamp holder receiving a light from the light source to guide upward, a diffusion film disposed on the light-guiding board, a shielding board and an outer housing. The diffusion film is used to uniform the light from the light-guiding board. The present disclosure utilizes the opaque second graphic segment on the outer housing and the light-penetrable first graphic segment on the shielding board to be overlapped to produce a contour luminous effect. The second graphic segment is smaller than the first graphic segment, and the second graphic segment is matched with the first graphic segment. In another way, the shielding board is formed with the first graphic segment and the second graphic segment, to produce a contour light-penetrable effect.

  • Publication number: 20150154119
    Abstract: A memory allocation and page address translation system includes a buddy memory allocator, a plurality of guest page tables, a memory management unit and a buddy translation lookaside buffer. The buddy memory allocator is configured for allocating machine physical memory space to a virtual machine monitor and a plurality of virtual machines. Each of the virtual machine monitor and the virtual machines receives memory chunks with different sizes. The guest page tables are configured for providing virtual address translation references for the virtual machine monitor and the virtual machines. The memory management unit is configured for translating a virtual address into a guest physical address. The buddy translation lookaside buffer is configured for translating the guest physical address into a machine physical address.
