Description

Technical Field

[0001] The present invention relates to the technical field of wireless communication terminals, and in particular to a wireless communication terminal based on Bluetooth low energy consumption technology. Background Art

[0002] Communication terminals are direct tools for people to enjoy different information applications. They are responsible for providing users with a good user interface, completing required business functions and accessing communication networks. In our daily lives, the types and functions of communication terminals produced by each manufacturer are different. One of the more commonly used ones is the wireless communication terminal based on Bluetooth low energy technology.

[0003] Existing wireless communication terminals based on Bluetooth low energy technology have built-in processors and Bluetooth modules, and the Bluetooth module and processor work together to complete the wireless communication function. Since the processor generates heat when working for a long time, the existing wireless communication terminals only use heat dissipation holes to dissipate heat. This heat dissipation method has low heat dissipation efficiency and cannot discharge the heat generated by the processor in time, which affects the service life of the processor. Summary of the invention

[0004] Based on the technical problem that the existing wireless communication terminal only uses the method of opening heat dissipation holes for heat dissipation, which has low heat dissipation efficiency and cannot timely discharge the heat generated by the processor, thus affecting the service life of the processor, the present invention proposes a wireless communication terminal based on Bluetooth low energy technology. The advantage is that the heat inside the shell is ensured to be discharged in time, thus increasing the service life of the device.

[0005] A wireless communication terminal based on Bluetooth low energy technology proposed in the present invention comprises a shell, a bottom inner wall of the shell is provided with a mounting column, and a circuit board is provided at the top of the mounting column, a processor and a Bluetooth module are provided on the top of the circuit board, antennas are provided on both side outer walls of the shell, an air inlet is provided on the bottom outer wall of the shell, and an air inlet tube is provided on the inner wall of the air inlet, a bracket is provided on the inner wall of the air inlet tube, a motor is provided at the bottom of the bracket, and a fan blade is connected to the output shaft of the motor, a heat-conducting column is provided at the bottom of the circuit board, a plurality of heat-conducting strips distributed at equal distances are provided on the outer walls around the heat-conducting column, the heat-conducting strips are in an S-shaped structure, and a plurality of heat-conducting protrusions are provided on the outer wall of the heat-conducting strip, an air outlet is provided on the top outer wall of the shell, a heat dissipation bin is provided on the inner wall of the air outlet, and heat dissipation holes are provided on the outer walls around the heat dissipation bin.

[0006] Preferably, the outer wall of the mounting column is provided with a flow hole, and the cross section of the flow hole is an isosceles trapezoidal structure. The flow hole can facilitate the air circulation in the housing and avoid the situation where the hot air is blocked by the mounting column.

[0007] Preferably, an air guide block is provided on the outer wall of the mounting column near the circulation hole, and the cross section of the air guide block is an isosceles triangle structure. The air guide block can play a good air guide effect, can quickly guide the hot air into the circulation hole for flow, and avoid the occurrence of hot air blockage.

[0008] Preferably, support pads are provided at the four corners of the outer wall at the bottom of the shell, and the support pads are made of rubber material. The support pads can increase the gap at the bottom of the shell, making it easier for air to enter the air inlet tube for circulation.

[0009] Preferably, a plurality of heat conducting sheets are provided on both inner walls of the housing, and the heat conducting sheets are in a W-shaped structure. The heat conducting sheets in the W-shaped structure can increase the effective heat dissipation area of ​​the housing and avoid the situation where the housing temperature rises.

[0010] Preferably, the outer wall of the heat conducting sheet is provided with a plurality of ventilation holes distributed at equal distances, and the inner wall of the ventilation holes is provided with heat conducting convex particles. The ventilation holes can prevent the heat conducting sheet from blocking the airflow, thereby improving the circulation efficiency of the airflow, and the heat conducting convex particles further increase the heat dissipation area of ​​the heat conducting sheet, thereby improving the heat dissipation effect on the housing.

[0011] Preferably, the inner wall of the housing above the circuit board is provided with a heat sink, and the outer wall of the heat sink is provided with a plurality of equidistant annularly distributed heat sinks, the heat sink is in a V-shaped structure, and the outer wall of the heat sink is provided with heat dissipation protrusions. The heat sink and the heat dissipation protrusions can increase the effective heat dissipation area of ​​the housing, ensure that the heat inside the housing can be quickly discharged from the heat dissipation bin, and further improve the heat dissipation effect of the device.

[0012] Preferably, the top inner wall of the shell is provided with a plurality of guide blocks, and the guide blocks are distributed on both sides of the air outlet. The guide blocks can play a good guiding effect, ensuring that all hot air can be discharged from the air outlet, and avoiding the occurrence of hot air deposition on the top of the shell.

[0013] Preferably, a guide plate is provided on the top inner wall of the heat dissipation chamber, and the cross section of the guide plate is a right triangle structure. The hot air at the top of the heat dissipation chamber can flow into the heat dissipation holes along the inclined surface of the guide plate, thereby preventing the hot air from being deposited in the heat dissipation chamber.

[0014] Preferably, a dust filter is provided at the bottom end of the air inlet cylinder, and the dust filter is arranged in an arc shape. The dust filter arranged in an arc shape can filter dust well, and prevent dust from entering the housing and causing pollution.

[0015] The beneficial effects of the present invention are:

[0016] 1. When in use, the motor can drive the fan blades to rotate, and the rotation of the fan blades drives the air flow in the shell. The fan blades can blow directly to the bottom of the circuit board. The heat-conducting columns, heat-conducting strips and heat-conducting protrusions can increase the effective heat-conducting area of ​​the circuit board, so that the heat on the surface of the circuit board can be quickly taken away by the flowing air and discharged out of the shell through the heat dissipation holes, thereby achieving a good heat dissipation effect, ensuring that the heat inside the shell is discharged in time, and increasing the service life of the equipment. Since the hot air is discharged from all sides of the heat dissipation bin, the top of the heat dissipation bin can be dust-proof to prevent dust from entering the shell from the air outlet. When dissipating heat, the heat dissipation holes can blow outward to blow away the dust that attempts to fall into the heat dissipation holes, further playing a dust-proof role;

[0017] 2. The circulation holes can facilitate the air circulation in the shell to avoid the situation where the hot air is blocked by the mounting column. The air guide block can play a good air guide effect and can quickly guide the hot air to the circulation holes for flow to avoid the situation where the hot air is blocked;

[0018] 3. The W-shaped heat-conducting sheet can increase the effective heat dissipation area of ​​the shell and avoid the temperature rise of the shell. The ventilation holes can prevent the heat-conducting sheet from blocking the airflow, thereby improving the circulation efficiency of the airflow. The thermal conductive bumps further increase the heat dissipation area of ​​the heat-conducting sheet and improve the heat dissipation effect of the shell.

[0019] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS
