An electronic device includes a display panel including a display surface on a front; a front panel surrounding the display panel; a circuit board that is disposed on a front side of a lower portion of the display panel and housed in the front panel; and a holder provided between the front of the display panel and a back of the circuit board. The holder includes a plurality of grooves each continuously extending in an up-down direction on a back of the holder facing the front of the display panel. The plurality of grooves are formed so as to be connected to each other. The front panel is formed with a through hole facing lower ends of the grooves.

The present disclosure relates to a vehicle-mounted heat dissipation system and a heat dissipation method. The vehicle-mounted heat dissipation system include: a display screen; a heat dissipation structure configured to define a heat dissipation cavity at the back surface of the display screen; an air-cooling heat dissipation device comprising an air supply device, an air inlet, and an air outlet; a water-cooling heat dissipation device comprising a water storage device and a water pipe; and a control device configured to control, if a temperature of the display screen is higher than a first temperature threshold, the vehicle-mounted heat dissipation system to be in an air-cooling heat dissipation mode, and also configured to control, if the temperature of the display screen is higher than a second temperature threshold, the vehicle-mounted heat dissipation system to be in a water-cooling heat dissipation mode.

An assembly facilitating installation of a steering column on an original passenger's side of a truck cab includes an aftermarket dash panel having a steering column opening configured to be located on the original passenger's side of the truck cab and an HVAC access opening configured to be located on an original driver's side of the truck cab. A first bracket has a forward portion for connection to original HVAC ductwork of the truck cab and has a rearward portion for connection to the aftermarket dash panel. The aftermarket dash panel comprises a single piece that extends from a left side of the truck cab to a right side of the truck cab. A method for moving a steering column of a truck cab from an original driver's side of the truck cab to an original passenger's side of the truck cab is also described.

An instrument panel including a potentially large display panel which can be recessed away from mis-operations includes mounting surface and air outlet assembly. The display panel is mounted on the mounting surface. The air outlet assembly includes air intake and outlet. The air intake can connect to an air conditioning system. The air outlet is disposed on the mounting surface, and contains the display terminal. A size of the display assembly is freely adjustable, and the structure of the instrument panel reduces a risk of mis-operating the display terminal while driving. Heat generated by the display terminal can be taken away by the air outlet for increasing a lifetime of the display terminal. A vehicle with the instrument panel is also provided.

A defroster structure includes: a window panel; an instrument panel; an air outlet member formed with an opening through which defrost air is blown out; and a duct member. The air outlet member includes an adjacent part forming a front edge of the opening and adjacent to the window panel, and a fixed part continuous to the adjacent part. The fixed part is fixed to the duct member at a position in front of a front end part of the window panel, which is exposed to the vehicle compartment, in cross-sectional view in a front-rear direction.

A front part structure of a vehicle cabin may include: an instrument panel including an air outlet at an end of the instrument panel on a passenger seat side; an air conditioner main body arranged inside the instrument panel at a center in a vehicle width direction; a cross beam arranged inside the instrument panel and connected to a right side and a left side of a vehicle body; and an air duct arranged inside the instrument panel and connecting the air conditioner main body to the air outlet. The air duct may extend in front of the passenger seat at a height lower than the cross beam.

An on-vehicle equipment operation device includes an air-conditioning duct that has an open end through which air-conditioned air blows, a display that is disposed outside the air conditioner and configured to display an image, an image forming optical element, and at least one equipment operation switch that is disposed at a lower edge of the open end. The image forming optical element is configured to form, as a floating image near the open end of the air-conditioning duct, a real image of the image that is displayed on the display. The floating image includes at least one equipment operation icon. The at least one equipment operation switch corresponds to the at least one equipment operation icon.

A front part structure of a vehicle cabin may include: an instrument panel including an air outlet at an end of the instrument panel on a passenger seat side; an air conditioner main body arranged inside the instrument panel at a center in a vehicle width direction; a cross beam arranged inside the instrument panel and connected to a right side and a left side of a vehicle body; and an air duct arranged inside the instrument panel and connecting the air conditioner main body to the air outlet. The air duct may extend in front of the passenger seat at a height lower than the cross beam.

An integrated display and ventilation assembly includes a display screen and a first air register. The first air register is displaceable between a first stowed position concealed behind the display screen and a first deployed position projecting from behind the display screen. A related method of ventilating a passenger compartment of a motor vehicle is also disclosed.

The present disclosure relates to a vehicle-mounted heat dissipation system and a heat dissipation method. The vehicle-mounted heat dissipation system include: a display screen; a heat dissipation structure configured to define a heat dissipation cavity at the back surface of the display screen; an air-cooling heat dissipation device comprising an air supply device, an air inlet, and an air outlet; a water-cooling heat dissipation device comprising a water storage device and a water pipe; and a control device configured to control, if a temperature of the display screen is higher than a first temperature threshold, the vehicle-mounted heat dissipation system to be in an air-cooling heat dissipation mode, and also configured to control, if the temperature of the display screen is higher than a second temperature threshold, the vehicle-mounted heat dissipation system to be in a water-cooling heat dissipation mode.
