Smart glasses include, for example, audio glasses, AR glasses, etc.

[0031] Combine the following Figures 1 to 14 The head mounted device of the present disclosure is described in detail.

[0032] Figure 1 is a schematic diagram showing a head mounted device 10 according to some embodiments of the present disclosure; Figure 2 Shown from another angle Figure 1 A schematic diagram of a head mounted device 10 in FIG. Figure 3 It shows Figure 1 An exploded view of the head mounted device 10 is shown.

[0033] like Figures 1 to 3 As shown, the head mounted device 10 may include a frame 110 , a pair of arms 120 , and at least one pluggable battery 130 .

[0034] The frame 110 is used to mount the display member 111. Each of the pair of arms 120 includes a first end 121 and a second end 122 opposite to 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 pluggable battery 130 is detachably connected to the second end 122 of a corresponding one of at least one of the pair of arms 120.

[0035] The head mounted device 10 of the present disclosure can manually remove the pluggable battery 130 and insert a new battery when the battery needs to be replaced.

[0036] The above implementation makes it easy for users to replace spare batteries, and the pluggable battery does not need to be charged with a charging cable, thereby avoiding the discomfort of wearing with a charging cable and the inconvenience of charging during travel.

[0037] 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 a nose pad or other feature to be placed on the user's nose. For example, the frame 110 and / or the 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.

[0038] 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 picture information. The displayed picture information may be provided or attached to (e.g., superimposed on) the physical environment excluding the physical environment. Among them, the physical environment refers to the physical world that people can interact with without the assistance of an electronic system. The computer-generated picture 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.

[0039] According to some embodiments, Figure 3 As shown, a pair of arms 120 extend from the frame 110. The first ends 121 of the pair of arms 120 can be connected to the frame 110 through a hinge 140, so that the pair of arms 120 can rotate relative to the frame 110 to fold or unfold the head mounted device 10.

[0040] 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.

[0041] 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, such as Fig.11 and Fig.12 As shown. Thus, 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 arms. A sleeve-type plug-in structure is used between the pluggable battery 130 and the arm 120, which 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.

[0042] 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, respectively, to facilitate the adsorption connection between the two.

[0043] According to some embodiments, in the case where 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 connector housing 1243 of the arm can be used to achieve a firm connection between the pluggable battery and the arm, and the stable support effect of the battery connector 124 on the pluggable battery is increased. Specifically, for example, in the case where 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 size of the pluggable battery is set to be slightly larger than the size of the sleeve structure at the second end of the arm, so that an interference fit is formed between the pluggable battery and the arm. Alternatively, in the case where 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 size of the second end of the arm is set to be slightly larger than the inner size of the pluggable battery, so that the two form an interference fit.

[0044] According to some embodiments, Figure 3As shown, at least one arm may include: an arm body 123 for connecting to the frame 110, an electronic motherboard assembly 1231 is arranged in the arm body 123; and a battery connector 124 connected between the arm body 123 and the pluggable battery 130, and an electrode line (for example, including a first electrode line 1241 and a second electrode line 1242) is arranged in the battery connector 124 for electrical connection with the corresponding pluggable battery 130 and the electronic motherboard assembly 1231. The above embodiment can realize that the pluggable battery 130 supplies power to the electronic motherboard assembly 1231 through the electrode line in the battery connector 124. In addition, the arm 120 sets the arm body 123 and the battery connector 124 as a split structure, which can facilitate the separate design of the material and structure of the battery connector 124, and is helpful to design a battery connector 124 that is easy to connect to the pluggable battery 130, increase the firmness and sealing of the connection between the pluggable battery 130 and the battery connector 124, and at the same time improve 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.

[0045] 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.

[0046] According to some embodiments, the electronic mainboard assembly 1231 is directly connected to the electrode wires by welding or by a terminal connector, 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.

[0047] According to some embodiments, the arm body 123 and the battery connector 124 are assembled and connected by means of snap fastening or glue dispensing.

[0048] 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, which is used to connect between the arm body 123 and the pluggable battery 130. Figure 6As shown, the first shell part 1243-1 is sleeved on the part of the second shell part 1243-2 close to the arm body, and the hardness of the first shell part 1243-1 is lower than the hardness of the second shell part 1243-2. ​​The first shell part 1243-1 is used to hang on the ear of the user. Setting its hardness to a lower level, that is, selecting a softer material, can achieve a buffering effect on the part in contact with the human body, thereby increasing the comfort of wearing. The second shell part 1243-2 is used to connect with the pluggable battery 130. Setting its hardness to a higher level, that is, selecting a harder material, can improve the connection firmness between the battery connector 124 and the pluggable battery 130, and prevent the pluggable battery 130 from falling off.

[0049] According to some other embodiments, the 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.

[0050] According to some embodiments, the first housing portion 1243-1 of the battery connector 124 may be made of soft glue or the like. Soft glue is also a flexible material with a soft feel, which is formed by injection molding of plastic, for example, but does not need to be vulcanized. The second housing portion 1243-2 of the battery connector 124 may be made of hard glue or the like. Hard glue is, for example, a hard material, such as hard rubber, which is obtained, for example, by vulcanizing natural rubber for a long time.

[0051] 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.

[0052] 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.

[0053] According to some embodiments, Figures 7 to 12 As shown, the inner wall of the second housing portion 1243-2 is provided with a first slot 1244 extending along at least part of the inner wall (for example, including extending along the entire periphery of the second housing portion 1243-2, or extending at a part 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 matches the first slot 1244, so as to enable the pluggable battery 130 to be detachably connected to the second housing portion 1243-2. Fig.13 and Fig.14As shown, 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 card slot 1244 of the second housing portion 1243-2. ​​At this time, the pluggable battery 130 and the battery connector 124 are matched 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.

[0054] Alternatively or additionally, Figures 7 to 12 As shown, the inner wall of the second housing portion 1243-2 is provided with a second slot 1245 extending along at least part of the inner wall (for example, including extending along the entire periphery of the second housing portion 1243-2, or extending at a part 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 matches the second slot 1245, so as to allow the pluggable battery 130 to be sealed and inserted into the second housing portion 1243-2. Fig.13 and Fig.14 As shown, 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 slot 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.

[0055] 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 ), for example, by structural assembly or injection molding.

[0056] According to some embodiments, when the battery connector is inserted into a pluggable battery, the first and / or second slots may be provided on the inner wall of the pluggable battery, and protrusions and / or sealing rings may be provided on the outer wall of the battery connector accordingly.

[0057] According to some embodiments, Figure 5 and Figure 6As shown, the battery connector 124 may include: a connector housing 1243; a first electrode line 1241 (e.g., a positive electrode line) (set in 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) (set in the connector housing 1243) and at least two second electrode springs 1247 (e.g., negative springs) connected to the second electrode line 1242; and a spring bracket 1248, the spring bracket 1248 is set in the end portion where the second end 122 of the connector housing 1243 is located, and a first through hole 1248-1 is set in the middle position of the spring bracket 1248. The first electrode spring 1246 is inserted in the first through hole 1248-1, and at least two second electrode springs 1247 are set 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 reverse, thereby achieving an effective anti-mismatch effect.
