The back plate 10 is surrounded by the frame 20 along the circumference, and the back plate 10 and the frame 20 are combined to form a receiving cavity, which is used to receive the mobile terminal 1000. When the mobile terminal 1000 and the mobile terminal accessory 100 are assembled, the back plate 10 is attached to the rear shell of the mobile terminal 1000.

[0053] In some embodiments, please refer to Figure 3 , Figure 3 An exploded view of a mobile terminal accessory 100 provided in some embodiments of the present application. The present application provides a mobile terminal accessory 100, comprising a heat dissipation component 30 and a sensing component 40.

The sensing component 40 is electrically connected to the heat dissipation component 30, and the sensing component 40 is used to sense the working state of the mobile terminal 1000, thereby turning on or off the heat dissipation component 30.

[0054] Among them, the heat dissipation component 30 can be a temperature difference heat dissipation component 30, a phase change heat dissipation component 30, a uniform temperature heat dissipation component 30, etc. It should be noted that the working principle of the temperature difference heat dissipation component 30 is that the cooling medium 322 transfers the heat absorbed by the high temperature area to the cold source, and dissipates the heat through the cold source; the working principle of the phase change heat dissipation component 30 is that the cooling medium 322 is a phase change material, and the cooling medium 322 absorbs heat from the high temperature area, thereby converting from liquid phase to gas phase to dissipate heat; the working principle of the uniform temperature heat dissipation component 30 is that the cooling medium 322 absorbs heat from the high temperature area and dissipates heat to the low temperature area, so as to balance the heat.

[0055] Preferably, the sensing component 40 can be a temperature sensing component, a pressure sensing component, an audio sensing component, etc.

[0057] The mobile terminal accessory 100 can intelligently turn on or off the heat dissipation component 30 according to the working state of the mobile terminal 1000 sensed by the sensing component 40, thereby improving the convenience of use for users and reducing power consumption. Specifically, when the mobile terminal 1000 is in a high-speed operation state, the heat dissipation component 30 is automatically turned on to dissipate heat for the mobile terminal 1000, and when the mobile terminal 1000 is in a non-high-speed operation state (such as a standby state), the heat dissipation component 30 is automatically turned off.

By using the power source 31 to provide operating power to the cooling structure 32, the cooling medium 322 can flow continuously and evenly in the cooling structure 32, and the effect of uniform heat dissipation can be achieved.

[0059] Exemplarily, the second plate 12 of the back plate 10 of the mobile terminal 100 is provided with a first receiving groove 121 for receiving the power source 31 .

It should be noted that when the variable volume chamber 311 is in the first state, the volume of the variable volume chamber 311 increases, and when the variable volume chamber 311 is in the second state, the volume of the variable volume chamber 311 decreases.

[0064] The variable volume chamber 311 of the piezoelectric power source 31 switches the working state to perform liquid intake and liquid discharge, and completes one power output from liquid intake to liquid discharge.

[0065] Exemplarily, the piezoelectric power source 31 includes an inlet plate 312 and an outlet plate 313.

The outlet plate 313 has a front side and a rear side along the X direction. When the outlet plate 313 and the second limiting protrusion 3162 abut, the front side of the outlet plate 313 abuts against the second limiting protrusion 3162, thereby realizing the one-way non-return function of the piezoelectric power source 31. Among them, the first limiting protrusion 3161 and the second limiting protrusion 3162 can also be respectively arranged on the rear side of the inlet plate 312 and the rear side of the outlet plate 313.

The cooling medium 322 flows in the cooling circuit formed by the cooling channel 321 and the power source 31. The cooling medium 322 absorbs heat when passing through the high temperature area of ​​the mobile terminal 1000. The cooling medium 322 releases heat to the outside when passing through the normal temperature area of ​​the mobile terminal 1000, thereby achieving temperature balance of the mobile terminal 1000.

The microphone 431 is used to receive the sound emitted by the speaker of the mobile terminal 1000 in the game scene, and the acoustic-electric conversion module 432 is used to convert the sound signal into an electrical signal. By using the acoustic-electric converter to convert the sound signal into an electrical signal, the heat dissipation component 30 of the mobile terminal accessory 100 can be automatically started in the game scene, thereby dissipating heat for the mobile terminal 1000.
