Description

Laminated main board heat radiation structure of intelligent watch Technical Field The utility model relates to the technical field of heat dissipation structures, in particular to a laminated main board heat dissipation structure of an intelligent watch. Background The smart watch integrates fashion and science and technology into a whole, has a common clock function, has a part of communication function of a mobile phone, is connected with the mobile phone through a built-in eSIM card or Bluetooth, can answer and dial a call, send and receive a short message, send and receive a micro message, and send and receive a QQ and other social software message reminding can be synchronized in real time without picking up the mobile phone, important information is not missed from the moment, so that is popular realization of rich functions is favored, the smart watch is benefited by the realization of abundant functions, a main board is used as a core carrier of the device, various functional chips and electronic elements are orderly connected, the communication chip on the main board supports various network modes, ensures that data can be stably transmitted in network environments such as 4G, wi-Fi and Bluetooth, and the storage chip provides safe and stable storage space for system operation and user data, and the smart watch becomes a high-efficiency life and health management assistant of modern people, and continuously brings innovated and revolutionized technology and application of the wearable device. CN219997488U discloses a circular intelligent watch main board with high space utilization rate, and relates to the technical field of intelligent watches. The circuit board comprises a PCB main board, wherein the PCB main board is a double-sided circular main board, a battery placement area is arranged on the back of the PCB main board, the battery placement area is a rectangular area, four corners of the battery placement area are close to the edge of the PCB board, and the outer side part of a frame of the battery placement area is a component welding area. Through setting up the PCB mainboard into circular structure, with battery space maximize, battery capacity is bigger, and the welding of components and parts is arranged and is not placed the position coincidence with the battery, and the radiating effect is good, and space utilization is high, has effectively reduced the thickness after the components and parts are installed for the watch is whole more fine thin that can do, and pleasing to the eye degree is better. In the design, the intelligent watch main board depends on the planar layout of the single-sided PCB, so that the longitudinal space is not fully excavated, all functional modules such as a battery, a chip and a sensor are concentrated on the front side and the back side of the PCB for tiling, the element sub-layout is limited in the same projection area, and the three-dimensional space in the watch body is not effectively utilized. Disclosure of utility model The utility model aims to provide a laminated main board radiating structure of an intelligent watch, which aims to solve the problem that the longitudinal space is not fully excavated due to the planar layout of a single-sided PCB. In order to achieve the above purpose, the present utility model provides the following technical solutions: The utility model provides a stacked mainboard heat radiation structure of intelligence wrist-watch, includes the watchcase, be provided with main PCB board in the watchcase, be provided with vice PCB board in the watchcase, be provided with the base plate in the watchcase, the base plate is located between main PCB board and the vice PCB board, the contact surface of base plate and main PCB board, vice PCB board is provided with liquid metal heat conduction layer respectively, be electrically connected between main PCB board and the vice PCB board. Preferably, a battery compartment is arranged in the watchcase and is arranged on the side of the main PCB, and the battery compartment is electrically connected with the main PCB.
