Embodiment Construction

[0030] The following is attached Figure 1-2 The application is described in further detail.

[0031] The embodiment of the present application discloses an efficient heat dissipation intelligent set-top box. refer to figure 1 and figure 2 The set-top box includes a casing 1 and a circuit board installed in the casing 1. A lifting assembly 2 is installed on the bottom of the casing 1. The lifting assembly 2 props the casing 1 away from the placement surface (that is, the place where the set-top box is placed and the bottom of the set-top box contact side).

[0032] see figure 2 , the lifting assembly 2 includes a number of support rods 21, the bottom of the casing 1 is provided with a cavity 7 for receiving the support rods 21, a sleeve 8 is fixed at the position of the cavity 7, and one end for driving the support rod 21 is installed in the sleeve 8 The driving member 22 moves away from or close to the bottom of the casing 1 .

[0033] see figure 2 , the driving mem...

Abstract

The invention relates to an efficient heat dissipation intelligent set top box which comprises a machine shell and a circuit board installed in the machine shell, the bottom of the machine shell is fixedly connected with a lifting assembly, the machine shell is further provided with a temperature sensor, and the temperature sensor is connected with a microcontroller. The microcontroller is preset with a temperature reference value so as to control the lifting assembly to move to support the machine shell when the heating temperature of the machine shell exceeds a preset value. The temperature sensor is arranged at the bottom of the machine shell to detect the temperature of the bottom of the machine shell in real time, when the temperature of the bottom of the machine shell is higher than the temperature reference value, the microcontroller controls the lifting assembly to lift the machine shell so as to increase the contact area between the bottom of the machine shell and air, and then the heat dissipation effect of the bottom of the machine shell is improved; and therefore, the local temperature of the bottom of the casing is not easy to be too high, and the set top box with the increased overall height also has the effect of facilitating the operation of a user. When the temperature of the set top box is at a normal value, the microcontroller controls the casing to reset so as to reduce the overall height of the set top box, so that the set top box is not easy to knock down.

Description

technical field [0001] This application relates to the field of digital television, in particular to an efficient heat dissipation intelligent set-top box. Background technique [0002] With the popularization of high-definition televisions, set-top boxes for supporting high-definition televisions are also widely used. A set-top box is a device that connects the TV to an external signal source. The content received by the set-top box is that it can receive digital content, including electronic program guides, Internet web pages, etc., in addition to the images and sounds that can be provided by analog TV. The set-top box includes a box body and various electronic components installed in the set-top box. [0003] In view of the above-mentioned related technologies, the inventor believes that there is a set-top box that is generally placed directly on the desktop. When the set-top box works for a long time, the heat dissipation between the bottom of the set-top box and the d...
