The present disclosure relates to a vibration reduction device, an electronic device and mobile equipment containing same. The vibration reduction device comprises: a first fixing component (10) which is a frame structure (11); a second fixing component (100) arranged in the center or near the center position of the first fixing component (10); and a vibration reduction connecting component (50) positioned between the first fixing component (10) and the second fixing component (100) and used for connecting both together. The vibration reduction connecting component (50) comprises a vibration reduction connecting frame (53) connected to the frame structure (11), and an inverted U-shaped structure (51) positioned in the vibration reduction connecting frame (53), connected to the lower part of the vibration reduction connecting frame (53) through supporting legs and connected with the second fixing component (100). The vibration reduction device of the present disclosure can provide excellent vibration reduction and impact-prevention protection for electronic products and precision electronic equipment. It is especially able to protect electronic products and precision electronic equipment installed on mobile equipment, such as a vehicle, against physical damage while under severe travelling conditions, as well as ensure their normal operation. The vibration reduction device according to the present disclosure not only has a simple structure and occupies little space, but also has simple installation and long service life, and can be suitable for varying load conditions.

An electrical system for a vehicle is provided. The electrical system includes a control unit configured to control operation of one or more vehicle systems. The electrical system also includes a multiplexed data bus communicatively coupled to the control unit, and configured to carry multiplexed signals to and from the control unit. The electrical system also includes a relay control box. The relay control box has one or more relays, and a controller. The controller is communicatively coupled to the multiplexed data bus, and is configured to decode the multiplexed control signals from the control unit to generate one or more decoded signals, and operate the one or more relays according to the decoded signal. A method of retrofitting a motor vehicle relay control box assembly is also provided.

An access port cover system, including a housing for an item, the housing defining interior and exterior regions and including an access port through which access to the item from the exterior region is provided, a cover inhibiting access through the access port from the exterior region to the interior region, and a fastener connectable to the housing and the cover. The fastener has an actuation portion for disconnecting the housing and the cover to permit access through the access port from the exterior region to the interior region, the actuation portion being inaccessible from the exterior region when the fastener is connected to the housing and the cover.

A sheet metal housing for an electronic controlling unit of a car is fixable in a holding element of the car. The housing has a first housing edge and a second housing edge arranged at opposite sides of the housing. First and second mounting elements are arranged at the first and second housing edges, respectively. The first and second mounting elements each comprise a first, a second and a third contact face for contacting the holding element to fix the housing in the holding element. The first contact face being arranged at a lower side, the second contact face being arranged at an outer side, and the third contact face being arranged at an upper side.

A structure of vehicle electric equipment including a restriction member restricting removal of a bolt for fixing a cover. The restriction member includes first and second portions. The first portion is disposed at a position overlapping with at least a part of a distal end of a connector of an electric cable when seen from an attachment/detachment direction and between the distal end and a portion of the housing opposed to the distal end in the attachment/detachment direction. The second portion is positioned on an axial extension of the bolt fixing the cover. Sum of a gap between the bolt fixing the cover and the second portion and a distance in the attachment/detachment direction between the distal end of the connector in a complete fitting state and the first portion is smaller than a length from an opening of the screw hole to a tip of the bolt.

An electrical component-attached wire harness includes a base material disposed in a vehicle, a wire harness disposed along the base material, and at least one electrical component to which an end portion of the wire harness is connected. For example, the at least one electrical component may include an electronic control unit.

A tractor including an intake pipe for supplying intake air to an intake unit of an engine body, and an engine harness for electrically connecting the engine body and an engine controller to each other. The intake pipe is provided with a rib formed along the longitudinal direction of the intake pipe, and the engine harnesses is partially supported by the rib.

A supporting assembly configured to fix a casing of an electronic device to a chassis and including a plate body, a cushioning component and a fastener. The plate body includes a mounting hole. The cushioning component is disposed through the mounting hole. The cushioning component includes a through hole. The fastener is disposed through the through hole of the cushioning component. A side of the fastener is configured to be fixed to the chassis, and the cushioning component is compressed by another side of the fastener and the chassis.

An in-vehicle computer includes a computer casing, a filtering structure, and a fan. The computer casing has a casing accommodating space and a vent opening communicating with the casing accommodating space. The filtering structure is detachably disposed at the vent opening. The fan is disposed in the casing accommodating space and spaced from the vent opening. A suction port of the fan is toward the vent opening. The fan generates an airflow, for dissipating heat from an electronic component in the casing accommodating space. By the filtering effect of the filtering structure, the particle amount in the airflow can be reduced. A vehicle includes a vehicle cage and the in-vehicle computer, disposed in the vehicle cage. The vent opening communicates with the cockpit space of the vehicle cage, so that the fan can draw lower-temperature air for enhancing the heat dissipation efficiency.
