Additionally, the external processing device may communicate with one or more other external processing devices via a network, which may be or include, for example, a local area network (LAN), a wide area network (WAN), an intranet, a metropolitan area network (MAN), the global Internet, or a combination thereof.

[0022] See also Figure 1 , Figure 1 1 is a schematic diagram of a charging device in an embodiment of the present application. The charging device 100 may include a housing assembly 200 and a circuit system 300 mounted on the housing assembly 200.

[0023] The housing assembly 200 is used to carry the circuit system 300 and the near-eye display device. When the housing assembly 200 carries and places the near-eye display device, the circuit system 300 can be electrically connected to the near-eye display device to power the near-eye display device. The circuit system 300 can be electrically connected to an external power source (such as a portable power source, mains power, etc.) to receive electrical energy and power the near-eye display device at the same time, and can also store electrical energy to power the near-eye display device when connected to the near-eye display device.

[0024] See also Figure 1 The housing assembly 200 has a first end 201 and a second end 202. In one embodiment, the first end 201 and the second end 202 are two end portions of the housing assembly 200 in the extension direction.

[0025] It should be noted that the terms "first", "second", etc., herein and in the following text are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, features defined as "first", "second", etc., etc. may explicitly or implicitly include one or more of the features.

[0026] The housing component 200 is disposed between the first end 201 and the second end 202 and protrudes from one side of the housing component 200 to form a protrusion 203 .

[0027] The housing component 200 is recessed between the first end 201 and the second end 202 and at the other side to form a recessed portion 204. That is, the housing component 200 is recessed at a side opposite to the protruding portion 203 to form a recessed portion 204. In some embodiments, the recessed portion 204 may be omitted.

[0028] The housing component 200 is recessed between the first end 201 and the protrusion 203 to form a receiving cavity 205. In one embodiment, the receiving cavity 205 is extended toward the first end 201. In one embodiment, the receiving cavity 205 is extended into the housing component 200 to penetrate the housing component 200.

[0029] The surface of the housing assembly 200 between the protrusion 203 and the second end 202 is recessed inwardly to form a receiving groove 206. In some embodiments, the receiving groove 206 can be omitted.

[0030] See also Figure 1 The circuit system 300 may include a first electrical interface 301 arranged at the second end 202, a second electrical interface 302 arranged in the accommodating groove 206, a function key 303 arranged on the side surface of the shell assembly 200, and a status indicator light 304 arranged on the surface between the first end 201 and the protrusion 203.

[0031] It is understandable that the names of "first electrical interface", "second electrical interface" and "electrical interface" can be interchanged in some embodiments. For example, in one embodiment, the "first electrical interface" in other embodiments is called the "second electrical interface", and correspondingly, the "second electrical interface" in other embodiments is called the "first electrical interface".

[0032] The first electrical interface 301 is electrically connected to an external power source (e.g., a removable power source, AC power, etc.) so that the circuit system 300 receives electrical energy transmitted from the external power source. The second electrical interface 302 is electrically connected to a near-eye display device to transmit electrical energy to the near-eye display device. The function key 303 is used to control the circuit system 300 to transmit electrical energy to the near-eye display device so as to receive electrical energy transmitted from an external power source. The status indicator light 304 can be used to display the status of the circuit system 300 during operation so that the user can better understand the status of the charging device 100 and the near-eye display device, such as the power status.

[0033] It can be understood that the installation position of each element in the first electrical interface 301, the second electrical interface 302, the function key 303 and the status indicator light 304 is not limited to the installation positions listed here. For example, the first electrical interface 301 can be installed at the first end 201, can be installed on the surface between the first end 201 and the protrusion 203, and can also be installed on the side surface of the housing assembly 200. For example, the second electrical interface 302 can be installed on the surface between the recessed portion 204 and the second end 202. For example, the function key 303 can be installed at the first end 201 or the second end 202, and can be installed on the surface between the first end 201 and the protrusion 203. For example, the status indicator light 304 can be installed at the first end 201 or the second end 202, and can also be installed on the side surface of the housing assembly 200.

[0034] See also Figure 2 , Figure 2 for Figure 1 A diagram showing the relationship between the charging device 100 and the near-eye display device in the illustrated embodiment. The near-eye display device 400 may include a device body 401 provided with a battery and an optical machine, and an optical waveguide lens 402 mounted at the end of the device body 401 and receiving light emitted by the optical machine. The battery in the device body 401 provides power for the normal operation of the near-eye display device 400. The optical waveguide lens 402 transmits light to the user's eyes for imaging.

[0035] The charging device 100 can be placed on a carrier such as a desktop, a bottom plate, etc., and the first end 201 and the second end 202 can contact the carrier to support the charging device 100. The raised portion 203 is arranged on a side of the charging device 100 away from the carrier. The recessed portion 204 is arranged on a side of the charging device 100 close to the carrier.

[0036] Of course, in some embodiments, due to different usage scenarios of the charging device 100, the surface between the protrusion 203 and the second end 202 contacts the carrier to support the charging device 100. In addition, the side surface of the housing assembly 200 may contact the carrier to support the charging device 100.

[0037] When the charging device 100 charges the near-eye display device 400, the near-eye display device 400 needs to be placed on the charging device 100. The device body 401 can be placed on the receiving groove 206, and the optical waveguide lens 402 will be placed in the receiving cavity 205. The housing assembly 200 is used to carry and place the near-eye display device 400. The device body 401 is electrically connected to the second electrical interface 302.

[0038] In some embodiments, the device body 401 can be detachably connected to the optical waveguide lens 402, and a second electrical interface 302 is also provided on the surface between the recessed portion 204 and the second end 202. The device body 401 can be placed alone on the surface between the recessed portion 204 and the second end 202 to be electrically connected to the second electrical interface 302.

[0039] It can be understood that when the charging device 100 is charging the near-eye display device 400, the accommodating cavity 205 can accommodate and protect the optical waveguide lens 402. In addition, the charging device 100 can also be portable, so that the near-eye display device 400 can be carried when the near-eye display device 400 is placed.
