Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted machines, in particular to a rapid heat dissipation and ventilation structure for a vehicle-mounted machine. Background Art

[0002] In-vehicle computer (ICM), short for in-vehicle infotainment system, refers to a multifunctional infotainment product installed inside a vehicle. Its primary function is to facilitate information communication between the driver and the vehicle, and between the vehicle and the outside world, thereby enhancing driving safety and entertainment. With technological advancements, in-vehicle computers have continuously evolved, evolving from early CD and DVD navigation functions to intelligent and information-based systems. In addition to traditional radio, music and video playback, and navigation, modern in-vehicle computers also feature 3G and telematics. They integrate with the vehicle's CAN-BUS technology to facilitate information communication between the driver and the vehicle, and between the vehicle and the outside world, enhancing user experience, service, and safety. Among these features, "I-Call" and "E-Call" are the most prominent. "I-Call" connects to a call center through the in-vehicle computer's built-in communication module, providing one-touch navigation, location-based location services, and remote services. "E-Call" automatically dials emergency assistance in the event of a serious accident. Vehicles also include location tracking and anti-theft monitoring. If a vehicle is stolen, the call center can collaborate with law enforcement to locate and track it.

[0003] Most high-precision in-vehicle positioning devices currently on the market (such as those used in driving test vehicles) have multiple chips on their motherboards, generating significant heat during operation. However, existing in-vehicle positioning devices suffer from poor heat dissipation, which can lead to frequent system crashes. While there are currently existing rapid heat dissipation and ventilation structures that can address this issue, these structures are relatively fixed in size, making them difficult to secure to motherboards of varying sizes and resulting in limited flexibility. Therefore, a rapid heat dissipation and ventilation structure for in-vehicle devices was developed. Utility Model Content
