[0052] In some embodiments, see Figure 2a-2c , Figure 2a-2c This is a structural diagram of a handheld terminal box provided by an embodiment of the utility model, such as Figure 2a-2c As shown, the handheld terminal box 300 also includes an upper shell 50 and a lower shell 60, and the lower shell 60 is surrounded by a first installation space 61, a second installation space 62 and a third installation space 63.

[0059] For further information, see Figure 3 , Figure 3 is a structural block diagram of a signal converter provided by an embodiment of the utility model, such as Figure 3 As shown, the signal converter 40 includes a signal conversion module 41 and an interface module 42;

[0060] The signal conversion module 41 is connected to the interface module 42, and the interface module 42 is also used to connect to the multimedia TV stick 100 and the AR / VR glasses 200 respectively;

[0061] The signal conversion module 41 is used to receive the first signal output by the multimedia TV stick 100, and obtain the signal type of the AR / VR glasses 200, so as to output a second signal to the AR / VR glasses 200 based on the signal type and the first signal. It should be noted that when the multimedia TV stick 100 is connected to the AR / VR glasses 200 through the interface module 42, since the signal interface of the multimedia TV stick 100 is generally an HDMI interface, the first signal output by the multimedia TV stick 100 to the signal conversion module 41 is an HDMI signal, and the signal interface of the AR / VR glasses 200 may include an HDMI signal interface or a USB Type C DP Alt Mode signal interface. Therefore, when the multimedia TV stick 100 outputs the first signal through the signal conversion module 41, it is also necessary to determine the signal interface type of the AR / VR glasses 200 to ensure that the signal output to the AR / VR glasses 200 can be correctly recognized by the AR / VR glasses 200.

[0062] In some embodiments, when the signal type of the AR / VR glasses 200 is an HDMI signal, the first signal output by the multimedia TV stick 100 can be directly transmitted to the AR / VR glasses 200 through the signal conversion module 41. It should be noted that when the signal type of the AR / VR glasses 200 is an HDMI signal, since the signal type of the AR / VR glasses 200 is consistent with that of the multimedia TV stick 100, it is not necessary to convert the signal when transmitting the signal, and the first signal is the second signal, so the signal conversion module 41 directly transmits the first signal to the AR / VR glasses 200.

[0063] For details, please refer to Figure 4a , Figure 4a is a circuit diagram of a signal conversion module provided by an embodiment of the utility model, such as Figure 4a As shown, the signal conversion module 41 includes a diode D2, a first interface chip J3 and a second interface chip J4; the first interface chip J3 is connected to the anode of the diode D2, and the cathode of the diode D2 is connected to the second interface chip J4. The first interface chip J3 is also used to connect to the multimedia TV stick 100, and the second interface chip J4 is also used to connect to the AR / VR glasses 200.

[0064] The first interface chip J3 is used to receive the first signal output by the multimedia TV stick 100, and transmit the first signal to the second interface chip J4, so that the AR / VR glasses 200 receive the signal output by the multimedia TV stick 100.

[0065] Among them, Figure 3 As shown, the signal converter 40 also includes a power control module 43; the power control module 43 is connected to the battery pack 30 and the multimedia TV stick 100 respectively, the anode of the diode D2 is connected to the first interface chip J3, and the power control module 43 is also connected to the second interface chip J4.

[0066] Specifically, the power control module 43 is used to receive the power output by the battery pack 30, and output the power to the multimedia TV stick 100 to power the multimedia TV stick 100; at the same time, when the first interface chip J3 is connected to the multimedia TV stick 100, the multimedia TV stick 100 will output power to the second interface chip J4 through the first interface chip J3, so as to power the AR / VR glasses 200 through the second interface chip J4. It should be noted that since the interface models of the multimedia TV stick 100 and the AR / VR glasses 200 are both HDMI signals, and the power carried by the HDMI signal during the transmission process is weak, it does not meet the power supply requirements of the AR / VR glasses 200. Therefore, the power supply end of the second interface chip J4 is also connected to the power control module 43, and the AR / VR glasses 200 are additionally powered by the power control module 43, thereby meeting the power supply requirements of the AR / VR glasses 200. The diode D2 is an anti-backflow diode. When the battery pack 30 additionally supplies power to the AR / VR glasses 200, the diode D2 is provided to prevent the additional power supply current of the battery pack 30 from flowing into the multimedia TV stick 100.

[0067] In some embodiments, when the signal type of the AR / VR glasses 200 is a USB Type C DP Alt Mode signal, the signal conversion module 41, after receiving the first signal output by the multimedia TV stick 100, will convert the first signal into a second signal, and finally output the second signal to the AR / VR glasses 200, so that the AR / VR glasses 200 can correctly identify the signal output by the multimedia TV stick 100.

[0068] For details, please refer to Figure 4b-4d , Figure 4b-4d is a circuit diagram of a signal conversion module provided by another embodiment of the utility model, such as Figure 4b-4d As shown, the signal conversion module 41 includes a third interface chip J5, a fourth interface chip J6 and a signal conversion chip U6; the signal conversion chip U6 is connected to the third interface chip J5 and the fourth interface chip J6 respectively, the third interface chip J5 is also used to connect to the multimedia TV stick 100, and the fourth interface chip J6 is also used to connect to the AR / VR glasses 200.

[0069] When the third interface chip J5 receives the first signal output by the multimedia TV stick 100, the third interface chip J5 will output the first signal to the signal conversion chip U6, so that the signal conversion chip U6 converts the first signal into a second signal. After the signal conversion chip U6 converts the first signal into a second signal, the signal conversion chip U6 will output the second signal to the fourth interface chip J6, so that the fourth interface chip J6 outputs the second signal to the AR / VR glasses 200.

[0070] In some embodiments, the power control module 43 is connected to the multimedia TV stick 100 and the signal conversion chip U6 respectively. The power control module 43 is used to obtain the output power of the battery pack 30 to power the multimedia TV stick 100. At the same time, the output power of the battery pack 30 is also output to the signal conversion chip U6. After receiving the output power, the signal conversion chip U6 will power the AR / VR glasses 200.

[0072] The driving unit 431 is used to receive an operation instruction from a user, and output a first driving instruction to the control unit 432 based on the operation instruction, so that the control unit 432 controls the battery pack 30 to output power based on the first driving instruction; and

[0073] The second driving instruction is output to the boost unit 433 , so that the boost unit 433 boosts the power output by the battery pack 30 based on the second driving instruction, and inputs the boosted power to the signal conversion module 41 of the multimedia TV stick 100 .
