[0034] The head-mounted device of the present disclosure is described in detail below with reference to FIG. 1 to FIG. 14 .

[0035] 1 is a schematic diagram showing a head-mounted device 10 according to some embodiments of the present disclosure; FIG2 is a schematic diagram showing the head-mounted device 10 in FIG1 from another angle; and FIG3 is an exploded view showing the head-mounted device 10 in FIG1 .

[0036] As shown in FIG. 1 to FIG. 3 , the head mounted device 10 may include a frame 110 , a pair of arms 120 , and at least one pluggable battery 130 .

[0037] The frame 110 is used to mount a display member 111. Each of the pair of arms 120 includes a first end 121 and a second end 122 opposite the first end 121, and the first end 121 of the pair of arms 120 is connected to the frame 110. Each of the at least one removable battery 130 is detachably connected to the second end 122 of a corresponding one of the at least one arm of the pair of arms 120.

[0038] When the battery of the head mounted device 10 of the present disclosure needs to be replaced, the pluggable battery 130 can be manually unplugged and disassembled and a new battery can be inserted and assembled.

[0039] The above embodiment makes it easy for users to replace spare batteries, and the pluggable battery does not need to be charged with a charging cable, avoiding the discomfort of wearing with a charging cable and the inconvenience of charging when traveling.

[0040] According to some embodiments, the frame 110 is worn on the user's head using one or more arms. The frame 110 can be positioned in front of the user's eyes to provide information within the user's field of view. The frame 110 can provide nose pads or other features for placement on the user's nose. For example, the frame 110 and / or arms 120 can enclose and support various internal components (including integrated circuit chips, processors, sensors, memory devices, input / output devices, and other circuits) to provide computing and functional operations for the head-mounted device 10.

[0041] According to some embodiments, the display element 111 installed in the frame 110 may be a lens or other display for transmitting light from the physical environment for viewing by the user and / or displaying computer-generated image information. The displayed image information may be provided excluding the physical environment or displayed in addition to (for example, superimposed on) the physical environment. The physical environment refers to the physical world that people can interact with without the assistance of an electronic system. Computer-generated image information may, for example, include multimedia images, and / or a real environment. A computer-generated real environment refers to a fully or partially simulated environment with which people interact via an electronic system. Examples of computer-generated realities include virtual reality, mixed reality, and augmented reality.

[0042] 3 , a pair of arms 120 extend from the frame 110. The first ends 121 of the arms 120 may be connected to the frame 110 via hinges 140 so that the arms 120 can rotate relative to the frame 110 to fold or unfold the head mounted device 10.

[0043] According to some embodiments, a pluggable battery 130 may be provided on at least one of the pair of arms 120. Specifically, one pluggable battery may be provided on each of the pair of arms 120, or one pluggable battery 130 may be provided on one of the pair of arms 120. The pluggable battery 130 may be provided at the second end 122 (i.e., the lower end) of at least one of the pair of arms 120.

[0044] According to some embodiments, the second end 122 of at least one arm 120 (specifically, the connector housing 1243, which will be further described below) has a sleeve structure, as shown in Figures 11 and 12. As a result, each of the at least one pluggable battery can be detachably inserted into the second end of a corresponding one of the at least one arm. The sleeve-type plug-in structure between the pluggable battery 130 and the arm 120 can facilitate manual insertion and removal of the pluggable battery 130, and there is no need to set a mechanical structure such as a disassembly button on the outside of the head-mounted device 10, thereby ensuring the integrity of the external form of the head-mounted device 10.

[0045] According to some other embodiments, the pluggable battery may be configured as a sleeve structure, and the second end of the arm may be inserted into the pluggable battery. Alternatively, magnets may be provided at the second end of the arm and the end of the pluggable battery to facilitate adsorption connection between the two.

[0046] According to some embodiments, when the pluggable battery 130 and the arm 120 adopt a sleeve-type plug-in structure, each pluggable battery forms an interference fit with the second end of a corresponding one of the at least one arms. Thus, the deformation of the arm's connector housing 1243 can be utilized to achieve a secure connection between the pluggable battery and the arm, thereby increasing the stable support provided by the battery connector 124 to the pluggable battery. Specifically, for example, when the pluggable battery is inserted into the second end of the arm, a protrusion 1321 can be provided on the outer wall of the pluggable battery, or the cross-sectional dimensions of the pluggable battery can be set to be slightly larger than the dimensions of the sleeve structure at the second end of the arm, so as to form an interference fit between the pluggable battery and the arm. Alternatively, when the second end of the arm is inserted into the pluggable battery, a protrusion 1321 can also be provided on the outer wall of the second end of the arm, or the cross-sectional dimensions of the second end of the arm can be set to be slightly larger than the inner dimensions of the pluggable battery, so as to form an interference fit between the two.

[0047] According to some embodiments, as shown in FIG. 3 , at least one arm may include: an arm body 123 for connecting to the frame 110 , with an electronic motherboard assembly 1231 disposed therein; and a battery connector 124 connected between the arm body 123 and the pluggable battery 130 , with electrode wires (e.g., including a first electrode wire 1241 and a second electrode wire 1242 ) disposed therein for electrically connecting to the corresponding pluggable battery 130 and the electronic motherboard assembly 1231. This embodiment enables the pluggable battery 130 to supply power to the electronic motherboard assembly 1231 via the electrode wires within the battery connector 124 . Furthermore, the arm 120 has the arm body 123 and the battery connector 124 as separate structures, facilitating the separate design of the material and structure of the battery connector 124 , thereby facilitating the design of a battery connector 124 that is easily connected to the pluggable battery 130 , enhancing the secure and sealed connection between the pluggable battery 130 and the battery connector 124 , and improving the wearing comfort of the arm 120 . Alternatively, the arm body 123 and the battery connector 124 of the arm 120 may also be provided as an integral structure.

[0048] According to some embodiments, the electronic motherboard assembly 1231 may include functional chips, circuits, electronic devices, etc., so as to provide computing and functional operations for the head-mounted device 10.

[0049] According to some embodiments, the electronic mainboard assembly 1231 and the electrode wires are directly connected by welding or connected through terminal connectors, etc., so as to achieve electrical connection between the pluggable battery 130 and the electronic mainboard assembly 1231 via the electrode wires in the battery connector.

[0050] According to some embodiments, the arm body 123 and the battery connector 124 are assembled and connected by snap fastening or gluing.

[0051] According to some embodiments, the battery connector 124 may include a connector housing 1243. The connector housing 1243 may include a first housing portion 1243-1 and a second housing portion 1243-2, configured to connect between the arm body 123 and the pluggable battery 130. As shown in FIG6 , the first housing portion 1243-1 is positioned over the portion of the second housing portion 1243-2 proximal to the arm body, and the hardness of the first housing portion 1243-1 is lower than that of the second housing portion 1243-2. ​​The first housing portion 1243-1 is designed to be attached to the user's ear. A lower hardness, i.e., a softer material, can provide a cushioning effect at the portion in contact with the body, thereby increasing wearing comfort. The second housing portion 1243-2 is designed to connect to the pluggable battery 130. A higher hardness, i.e., a harder material, can enhance the secure connection between the battery connector 124 and the pluggable battery 130 and prevent the pluggable battery 130 from falling off.

[0052] According to some other embodiments, the above-mentioned first shell part can be used to connect with the arm body, and the second shell part is used to connect between the first shell part and the pluggable battery, wherein the hardness of the first shell part is lower than the hardness of the second shell part, thereby achieving a buffering effect on the part in contact with the human body, thereby increasing the wearing comfort.

[0053] According to some embodiments, the first housing portion 1243-1 of the battery connector 124 can be made of soft rubber, for example. Soft rubber is a flexible material with a soft feel. For example, it is formed from plastic through injection molding without undergoing a vulcanization process. The second housing portion 1243-2 of the battery connector 124 can be made of hard rubber, for example. Hard rubber is a hard material, such as hard rubber, which is obtained by, for example, long-term vulcanization of natural rubber.

[0054] According to some embodiments, the first housing portion 1243 - 1 of the battery connector 124 is connected to the second housing portion 1243 - 2 by injection molding, etc. Alternatively, the first housing portion 1243 - 1 may also be adhered to the second housing portion 1243 - 2 .

[0055] According to some other embodiments, the first shell portion 1243 - 1 and the second shell portion 1243 - 2 may also be made of the same material, and in this case, the two may be integrally formed.

[0056] According to some embodiments, as shown in Figures 7 to 12, the inner wall of the second housing portion 1243-2 is provided with a first latching slot 1244 that extends along at least a portion of the inner wall (for example, including extending along the entire periphery of the second housing portion 1243-2, or extending along a portion of the periphery of the second housing portion 1243-2), and the outer wall of the pluggable battery 130 (specifically, the outer wall of the cover 132 of the pluggable battery 130) is provided with a protrusion 1321 that cooperates with the first latching slot 1244 to allow the pluggable battery 130 to be detachably connected to the second housing portion 1243-2. ​​As shown in Figures 13 and 14, when the pluggable battery 130 is inserted into the second housing portion 1243-2 of the battery connector 124, the protrusion 1321 on the outer wall of the pluggable battery 130 is embedded in the first latching slot 1244 of the second housing portion 1243-2. At this time, the pluggable battery 130 and the battery connector 124 are engaged through the card points to increase the connection firmness between the pluggable battery 130 and the battery connector 124 and increase the stable support effect of the battery connector 124 on the pluggable battery 130.

[0057] Alternatively or additionally, as shown in Figures 7 to 12, the inner wall of the second housing portion 1243-2 is provided with a second latching groove 1245 that extends along at least a portion of the inner wall (for example, including extending along the entire periphery of the second housing portion 1243-2, or extending along a portion of the periphery of the second housing portion 1243-2), and the outer wall of the pluggable battery 130 (specifically, the outer wall of the cover 132 of the pluggable battery 130) is provided with a sealing ring 1322 that cooperates with the second latching groove 1245 to ensure that the pluggable battery 130 is sealedly inserted into the second housing portion 1243-2. ​​As shown in Figures 13 and 14, when the pluggable battery 130 is inserted into the second housing portion 1243-2 of the battery connector 124, the sealing ring 1322 on the outer wall of the pluggable battery 130 is embedded in the second latching groove 1245 of the second housing portion 1243-2. At this time, the connection sealing between the pluggable battery 130 and the battery connector 124 can be increased, so that the connection between the two can achieve waterproof and dustproof effects.

[0058] According to some embodiments, the sealing ring 1322 is connected to the outer wall of the pluggable battery 130 (specifically, the cover 132 of the pluggable battery 130 ) by, for example, structural assembly or injection molding.

[0059] According to some embodiments, when the battery connector is inserted into a pluggable battery, the above-mentioned first card slot and / or second card slot can be set on the inner wall of the pluggable battery, and a protrusion and / or a sealing ring can be set on the outer wall of the battery connector accordingly.

[0060] According to some embodiments, as shown in FIG5 and FIG6 , the battery connector 124 may include: a connector housing 1243; a first electrode line 1241 (e.g., a positive electrode line) (disposed within the connector housing 1243) and a first electrode spring 1246 (e.g., a positive spring) connected to the first electrode line 1241; a second electrode line 1242 (e.g., a negative electrode line) (disposed within the connector housing 1243) and at least two second electrode springs 1247 (e.g., a negative spring) connected to the second electrode line 1242; and a spring bracket 1248, the spring bracket 1248 being disposed within the end portion of the connector housing 1243 where the second end 122 is located, and having a first through hole 1248-1 disposed in the middle of the spring bracket 1248. The first electrode spring 1246 is inserted into the first through hole 1248-1, and the at least two second electrode springs 1247 are disposed around the periphery of the spring bracket 1248. The above embodiment can effectively prevent battery short circuit by setting the first electrode spring 1246 in the middle of the spring bracket 1248 and setting at least two second electrode springs 1247 around the spring bracket 1248, and at the same time, the pluggable battery 130 can be connected to the positive and negative electrode springs on the battery connector 124 regardless of whether it is inserted forward or backward, thereby achieving an effective anti-misconnection effect.

[0061] According to some embodiments, the first electrode spring 1246 is connected to the first electrode line 1241, for example, by welding. The second electrode spring 1247 is connected to the second electrode line 1242, for example, by welding. The first electrode spring 1246 is connected to the spring bracket 1248, for example, by means of an assembly snap or hot melt. The spring bracket 1248 is connected to the connector housing 1243, for example, by means of glue dispensing or snaps. The second electrode spring 1247 is connected to the connector housing 1243, for example, by means of a snap or hot melt.

[0062] According to some other embodiments, the first electrode spring 1246 and the second electrode spring 1247 can be elastically pressed against the electrode terminals of the pluggable battery 130. Alternatively, the first electrode spring and the second electrode spring can also be configured as electrode contacts.

[0063] According to some other embodiments, the first electrode spring and the at least one second electrode spring may both be disposed at the periphery of the spring bracket.

[0064] According to some other embodiments, only one second electrode spring may be provided. In this case, both the first electrode spring and the second electrode spring are provided at the periphery of the spring bracket.

[0065] According to some embodiments, the pluggable battery 130 may include: a battery shell 131, the battery shell 131 having an open end 1311; a cover 132, the cover 132 covers the open end 1311, and a second through hole 1323 is provided at an intermediate position of the cover 132; a first electrode terminal 133, the first electrode terminal 133 is inserted into the second through hole 1323; and a second electrode terminal 134, the second electrode terminal 134 is provided at the periphery of the cover 132. When the pluggable battery 130 is inserted into the battery connector 124, the first electrode terminal 133 is crimped with the first electrode spring 1246, and the second electrode terminal 134 is selectively crimped with one of the at least two second electrode springs 1247 (when the pluggable battery is inserted into the battery connector in the forward direction, the second electrode terminal 134 is crimped with one of the at least two second electrode springs 1247, and when the pluggable battery is inserted into the battery connector in the reverse direction, the second electrode terminal 134 is crimped with the other of the at least two second electrode springs 1247). The above embodiment, by arranging the first electrode terminal 133 in the middle of the cover and the second electrode terminal 134 at the periphery of the cover, can effectively prevent battery short circuits and simultaneously enable the pluggable battery 130 to connect to the positive and negative electrode springs on the battery connector 124 regardless of whether it is inserted in the forward or reverse direction, thereby achieving an effective foolproofing effect.

[0066] According to some other embodiments, the pluggable battery 130 may also not include the cover 132, that is, the battery housing and the cover are provided as an integral structure. In this case, the first electrode terminal and the second electrode terminal are provided on the end surface of the battery housing.

[0067] According to some other embodiments, the first electrode terminal and the second electrode terminal may both be disposed at a periphery of the cover.

[0068] According to some embodiments, the first electrode terminal 133 , the second electrode terminal 134 and the cover 132 are connected by injection molding or the like.
