[0001] This invention relates to the field of electronic devices, and more specifically to a head-mounted electronic device. Background Technology

[0002] Currently, with technological advancements, intelligent electronic devices are diversifying, ranging from common handheld devices like smartphones and tablets to relatively niche head-mounted electronic devices such as AR and VR devices. Head-mounted electronic devices require batteries to function properly. To ensure a good user experience, existing batteries are lightweight but have short battery life, necessitating frequent replacements. However, the current limitations of rapid battery replacement in head-mounted electronic devices prolong user waiting times, thus diminishing the user experience. Summary of the Invention

[0003] The main objective of this invention is to provide a head-mounted electronic device that solves the problem of the difficulty in quickly replacing batteries in traditional head-mounted electronic devices.

[0004] To achieve the above objectives, the present invention proposes a head-mounted electronic device comprising a strap, a battery cover, a first transmission component, a second transmission component, and a drive structure. The strap has an mounting opening. The battery cover is slidably mounted on the battery body and is capable of reciprocating along a first direction to open or close the mounting opening. The first transmission component includes a battery holder movable along a second direction, which is detachably connected to the battery body and is positioned directly opposite the mounting opening. The second transmission component is connected to the battery cover. The drive structure is driven by both the battery holder and the second transmission component, and is used to drive the battery holder and the battery body to move along the second direction, and to drive the second transmission component and the battery cover to move along the first direction so that the battery body is exposed outside the mounting opening. The first direction is perpendicular to the second direction.

[0005] Optionally, the second transmission assembly includes a coil spring, a mounting gear, and a mounting bracket. The mounting bracket has a receiving cavity and a connection port communicating with the receiving cavity. The mounting gear includes a rotating part and a mounting part connected to each other. The rotating part is connected to the output end of the drive structure, and the mounting part is rotatably connected to the mounting bracket. One end of the coil spring is connected to the mounting part, and the other end extends out of the connection port and is connected to the battery cover. The rotating part rotates to drive the coil spring to rotate, so that the battery cover moves along the first direction.

[0006] Optionally, the mounting bracket includes a guide portion extending along the first direction, and the coil spring is slidable relative to the guide portion.

[0007] Optionally, the mounting bracket further includes a positioning plate disposed within the receiving cavity, the positioning plate being positioned near the connection port, the positioning plate being inclined, and the coil spring being slidable relative to the positioning plate.

[0008] Optionally, the head-mounted electronic device further includes a limiting component, which is rotatably connected to the end of the connection port, and is disposed opposite to the positioning plate. The coil spring has a limiting opening, and the limiting component is used to engage with the limiting opening.

[0009] Optionally, the limiting component includes a limiting block and a rotating shaft. The receiving portion has an installation groove at its end near the connection port. The rotating shaft is disposed in the installation groove. The limiting block includes a connecting portion and a limiting portion connected together. The connecting portion is rotatably sleeved on the rotating shaft. The limiting portion extends out of the installation groove and is used to engage with the limiting port.

[0010] Optionally, the rotating shaft includes a first connecting segment and a second connecting segment connected together, a stepped surface is formed between the first connecting segment and the second connecting segment, and the connecting part is rotatably sleeved on the outside of the first connecting segment;

[0011] A stop is provided on the opening of the mounting groove, and the connecting part is limited to the step surface and the stop.

[0012] Optionally, the drive structure includes a drive gear and a transmission gear, wherein the drive gear meshes with the transmission gear, and the transmission gear meshes with the rotating part.

[0013] Optionally, the first transmission assembly further includes a first transmission component and a second transmission component. The first transmission component includes a transmission shaft, a connecting gear, and a first bevel gear. Both the connecting gear and the first bevel gear are connected to the transmission shaft, and the connecting gear meshes with the drive gear. The second transmission component includes a screw and a second bevel gear connected to each other. The second bevel gear meshes with the first bevel gear. The screw is threadedly connected to the battery holder. The battery holder has a mounting cavity, and the battery body is detachably disposed within the mounting cavity.

[0014] Optionally, the drive gear includes a drive portion and a knob portion connected to each other, the drive portion meshing with the transmission gear and the connecting gear, and the knob portion extending beyond the strap; and / or,

[0015] The battery body is provided with a guide protrusion that extends along the second direction, and the battery holder is provided with a guide groove, wherein the guide protrusion can slide relative to the groove wall of the guide groove.

[0016] In this invention, the strap is a rigid strap worn behind the user's head, with an installation opening at the top for easy battery replacement. A battery cover is slidably mounted on the battery body, sliding left and right to open or close the installation opening. The battery body is detachably connected to the battery holder, which can move up and down to allow the battery to extend upwards for replacement when its power is low or worn. With the battery body corresponding to the installation opening, it can be removed from the head-mounted electronic device by the operator when it extends upwards beyond the opening. The battery cover is connected to a second transmission assembly, with a drive structure acting as a power source. The drive structure is connected to both the battery holder and the second transmission assembly, driving the battery holder to move up and down, which in turn moves the battery body up and down. Simultaneously, the drive structure moves the second transmission assembly left and right, which in turn moves the battery cover, causing it to detach from the battery body and expose it outside the installation opening.

[0017] When the head-mounted electronic device is in normal use, the battery cover is placed over the battery body to prevent it from detaching from the mounting port and the strap, and also to prevent dust and other contaminants from entering the battery body through the mounting port. When the battery needs to be replaced, the drive structure drives the battery holder to move the battery body upwards. Simultaneously, the drive structure drives the second transmission component to move the battery cover to the left, opening the mounting port. This allows the battery cover to detach from the battery body, exposing the battery body outside the mounting port. The operator then removes the battery body from the head-mounted electronic device and places a new battery body through the mounting port onto the first transmission component. The drive structure then drives the first transmission component to move the new battery body downwards. Simultaneously, the drive structure drives the second transmission component to move the battery cover to the right, closing the mounting port and placing the battery cover over the new battery body, thus completing the battery replacement.

[0018] This invention uses a driving structure to drive the battery holder to move the battery body vertically, while simultaneously driving a second transmission component to move the battery cover plate horizontally, allowing the battery body to protrude from the mounting opening. This facilitates battery replacement for operators, enabling rapid battery replacement, reducing user waiting time, and improving user experience. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0033] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0034] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0035] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0036] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0037] In this invention, the descriptions of directions such as "up," "down," "front," "back," "left," and "right" are as follows: Figure 1 The directions shown are for reference only and are used to interpret the location. Figure 1 The relative positional relationship between the components in the shown posture is such that if the specific posture changes, the directional indication will also change accordingly.

[0038] This invention provides a head-mounted electronic device.

[0039] The first direction is Figure 1 The left and right directions, the second direction is Figure 1 The up and down directions in the middle.

[0040] In one embodiment, such as Figures 1 to 8As shown, the head-mounted electronic device 100 includes a strap 10, a battery cover 70, a first transmission assembly 20, a second transmission assembly 30, and a drive structure 40. The strap 10 has an installation port 11. The battery cover 70 is slidably disposed on the battery body 60 and can reciprocate along a first direction to open or close the installation port 11. The first transmission assembly 20 includes a battery holder 23 that can move along a second direction. The battery holder 23 is detachably connected to the battery body 60, and the battery body 60 is disposed corresponding to the installation port 11. The second transmission assembly 30 is connected to the battery cover 70, and the battery cover 70 is slidably disposed on the battery body 60. The drive structure 40 is driven to the battery holder 23 and the second transmission assembly 30, respectively. The drive structure 40 is used to drive the battery holder 23 and the battery body 60 to move along the second direction, and to drive the second transmission assembly 30 and the battery cover 70 to move along the first direction so that the battery body 60 is exposed outside the installation port 11. The first direction is perpendicular to the second direction.

[0041] The strap 10 is a rigid strap worn behind the user's head. The top of the strap 10 has an installation opening 11 for easy replacement of the battery body 60. A battery cover 70 is slidably mounted on the battery body 60 and can slide left and right to open or close the installation opening 11. The battery body 60 is detachably connected to the battery holder 23, which can move up and down to allow the battery body 60 to extend upwards for replacement when its power is low or it is worn. With the battery body 60 positioned corresponding to the installation opening 11, and the battery body 60 extending upwards beyond the installation opening 11, the operator can easily remove the battery body 60 from the head-mounted electronic device 100. The battery cover 70 is connected to the second transmission assembly 30. The drive structure 40 serves as a power source to provide power. The drive structure 40 is connected to the battery holder 23 and the second transmission assembly 30 respectively. The drive structure 40 drives the battery holder 23 to move in the up-down direction, and the battery holder 23 drives the battery body 60 in the up-down direction. At the same time, the drive structure 40 drives the second transmission assembly 30 to move in the left-right direction, and the second transmission assembly 30 drives the battery cover 70 to move in the left-right direction, so that the battery cover 70 is detached from the battery body 60, and the battery body 60 can be exposed outside the mounting port 11.

[0042] When the head-mounted electronic device 100 is in normal use, the battery cover 70 covers the battery body 60 to prevent the battery body 60 from coming off the strap 10 through the mounting port 11, and also to prevent dust and other contaminants from entering the battery body 60 through the mounting port 11. When the head-mounted electronic device 100 needs a battery replacement, the drive structure 40 drives the battery holder 23 to move the battery body 60 upward. At the same time, the drive structure 40 drives the second transmission component 30 to move the battery cover 70 to the left to open the mounting port 11, so that the battery cover 70 is detached from the battery body 60 and the battery body 60 can be exposed outside the mounting port 11. Then, the operator removes the battery body 60 from the head-mounted electronic device 100 and places the new battery body 60 from the mounting port 11 onto the first transmission component 20. The drive structure 40 drives the first transmission component 20 to move the new battery body 60 downward. At the same time, the drive structure 40 drives the second transmission component 30 to move the battery cover 70 to the right to close the mounting port 11, so that the battery cover 70 covers the new battery body 60, thereby realizing the replacement of the battery body 60.

[0043] The present invention drives the battery holder 23 through the driving structure 40 to move the battery body 60 in the vertical direction. At the same time, it drives the second transmission component 30 to move the battery cover 70 in the horizontal direction, so that the battery body 60 can be exposed outside the mounting port 11, making it convenient for operators to replace the battery body 60. This enables the battery body 60 to be replaced quickly, reduces the user's waiting time for battery replacement, and improves the user experience.

[0044] Specifically, the head-mounted electronic device 100 also includes a housing (not shown), which is placed on the strap 10. The battery holder 23 can slide relative to the housing in the vertical direction. By setting the housing, the vertical movement of the battery holder 23 and the battery body 60 is more stable and reliable.

[0045] In one embodiment, please refer to the reference Figure 3 and Figure 4 The second transmission assembly 30 includes a coil spring 31, a mounting gear 32, and a mounting bracket 33. The mounting bracket 33 forms a receiving cavity 331 and a connection port 332 communicating with the receiving cavity 331. The mounting gear 32 includes a rotating part 321 and a mounting part 322 connected to each other. The rotating part 321 is connected to the output end of the drive structure 40, and the mounting part 322 is rotatably connected to the mounting bracket 33. One end of the coil spring 31 is connected to the mounting part 322, and the other end extends out of the connection port 332 and is connected to the battery cover 70. The rotating part 321 rotates to drive the coil spring 31 to rotate, so that the battery cover 70 moves along the first direction.

[0046] The mounting bracket 33 has a receiving cavity 331 for accommodating the coil spring 31. A connecting port 332 is formed at the top of the mounting bracket 33, communicating with the receiving cavity 331. The mounting gear 32 includes a rotating part 321 and a mounting part 322, which are connected. The second transmission assembly 30 is connected to the output end of the drive structure 40 via the rotating part 321. The drive structure 40 drives the rotating part 321 to rotate, and the mounting part 322 can rotate relative to the mounting bracket 33. A portion of the coil spring 31 is retractably coiled within the receiving cavity 331, while the other portion extends out of the receiving cavity 331. The two ends of the coil spring 31 are a fixed end 312 and a movable end 313, respectively. The fixed end 312 is connected to the mounting part 322 to achieve the installation and fixation of the coil spring 31. Specifically, the mounting part 322 has a helical groove, and the fixed end 312 extends into the helical groove and is then fixed with adhesive. The movable end 313 extends out of the connection port 332 and connects to the battery cover 70, thereby connecting the second transmission component 30 to the battery cover 70. The drive structure 40 drives the rotating part 321 and the mounting part 322 to rotate. The mounting part 322 drives the coil spring 31 to rotate, and the coil spring 31 drives the battery cover 70 to move in the left and right directions, thereby realizing the left and right movement of the battery cover 70 relative to the battery body 60.

[0047] Specifically, there can be two coil springs 31. The mounting bracket 33 forms two receiving cavities 331, which are spaced apart in the front-to-back direction. The fixed ends 312 of both coil springs 31 are connected to the mounting part 322, and the movable ends 313 of both coil springs 31 are connected to the battery cover 70. By setting two coil springs 31, the second transmission assembly 30 can drive the battery cover 70 to move in the left-to-right direction more stably and reliably.

[0048] In one embodiment, please refer to the reference Figure 3 and Figure 4 The mounting bracket 33 includes a guide portion 3341 that extends along a first direction, and the coil spring 31 can slide relative to the guide portion 3341.

[0049] The side plate 334 is connected to the periphery of the bottom plate 333, and the side plate 334 and the bottom plate 333 cooperate to form a receiving cavity 331. The side plate 334 includes a guide portion 3341 and a receiving portion 3342. The guide portion 3341 and the receiving portion 3342 are connected, and a connection port 332 is formed between the ends of the guide portion 3341 and the receiving portion 3342. The receiving portion 3342 extends in the same direction as the periphery of the bottom plate 333. The guide portion 3341 extends in the left and right direction. The coil spring 31 can slide relative to the guide portion 3341. The guide portion 3341 guides the sliding of the coil spring 31 in the left and right direction. In addition, the guide portion 3341 also guides the sliding of the battery cover 70 in the left and right direction. By setting the guide portion 3341, the sliding of the battery cover 70 in the left and right direction can be more stable and reliable.

[0050] In one embodiment, please refer to the reference Figure 3 and Figure 4 The mounting bracket 33 also includes a positioning plate 335, which is disposed in the receiving cavity 331. The positioning plate 335 is located near the connection port 332 and is inclined. The coil spring 31 can slide relative to the positioning plate 335.

[0051] The positioning plate 335 is installed and fixed by connecting to the base plate 333. The positioning plate 335 is set in the receiving cavity 331 and close to the connection port 332. The positioning plate 335 is inclined. Specifically, the positioning plate 335 is inclined from bottom to top towards the direction close to the battery body 60. The coil spring 31 can slide relative to the positioning plate 335. By setting the positioning plate 335 to position and guide the coil spring 31, the coil spring 31 can smoothly and stably extend out of the connection port 332, thereby realizing the stable and reliable movement of the battery cover 70 in the left and right directions.

[0052] In one embodiment, please refer to the reference Figures 4 to 6 The head-mounted electronic device 100 also includes a limiting component 50, which is rotatably connected to the end of the connection port 332. The limiting component 50 is disposed opposite to the positioning plate 335. The coil spring 31 has a limiting port 311, and the limiting component 50 is used to be inserted into the limiting port 311.

[0053] The limiting component 50 is rotatably connected to the end of the receiving portion 3342, allowing the limiting component 50 to rotate relative to the receiving portion 3342. The limiting component 50 is positioned opposite the positioning plate 335. A limiting opening 311 is located near the movable end 313 of the coil spring 31. The limiting component 50 engages with the limiting opening 311 to limit the coil spring 31, preventing it from rotating excessively and making it difficult for the battery cover 70 to return to the battery body 60, thus making the use of the coil spring 31 more convenient. Furthermore, the positioning plate 335 allows the limiting component 50 to engage with the limiting opening 311 when it moves to the positioning plate 335, making the limiting process of the limiting component 50 quicker and more convenient.

[0054] In one embodiment, please refer to the reference Figures 4 to 6 The limiting component 50 includes a limiting block 51 and a rotating shaft 52. The receiving part 3342 has an installation groove 336 at its end near the connection port 332. The rotating shaft 52 is disposed in the installation groove 336. The limiting block 51 includes a connecting part 511 and a limiting part 512 connected to each other. The connecting part 511 is rotatably sleeved on the outside of the rotating shaft 52. The limiting part 512 extends out of the installation groove 336 and is used to engage with the limiting port 311.

[0055] The mounting groove 336 is formed at the end of the receiving portion 3342 near the connecting port 332, and the mounting groove 336 has a downward-facing opening. The rotating shaft 52 is inserted into the mounting groove 336 from the side, and the connecting portion 511 of the limiting block 51 is rotatably sleeved on the rotating shaft 52. The limiting portion 512 extends out of the mounting groove 336 through the opening, and is used to engage with the limiting opening 311 to limit the coil spring 31, thereby stopping the coil spring 31 from rotating.

[0056] In one embodiment, please refer to the reference Figure 6 The rotating shaft 52 includes a first connecting section 521 and a second connecting section 522 connected together. A stepped surface is formed between the first connecting section 521 and the second connecting section 522. The connecting part 511 is rotatably sleeved on the outside of the first connecting section 521. A stop part 337 is provided on the groove of the mounting groove 336. The connecting part 511 is limited between the stepped surface and the stop part 337.

[0057] The rotating shaft 52 includes a first connecting section 521 and a second connecting section 522. The first connecting section 521 is connected to the second connecting section 522, and the cross-sectional area of ​​the second connecting section 522 is larger than that of the first connecting section 521, so that a stepped surface is formed between the second connecting section 522 and the first connecting section 521. The connecting part 511 is rotatably sleeved on the first connecting section 521. The stop part 337 is provided on the groove of the mounting groove 336 and is located close to the bottom plate 333. The connecting part 511 is limited between the stepped surface and the stop part 337. By setting the stepped surface and the stop part 337 for limiting, the limiting block 51 is prevented from shaking or disengaging from the rotating shaft 52, so that the limiting effect of the limiting component 50 is better.

[0058] The first connecting section 521 and the second connecting section 522 can be an integral structure, saving assembly steps between the first connecting section 521 and the second connecting section 522 and reducing assembly errors. When the first connecting section 521 and the second connecting section 522 are an integral structure, during installation, the connecting part 511 is first rotatably fitted onto the first connecting section 521 and abuts against the stepped surface. Then, the first connecting section 521 is inserted into the mounting groove 336 until the connecting part 511 abuts against the stop part 337. Then, the second connecting section 522 is fixed to the groove wall of the mounting groove 336 with adhesive, so that the rotating shaft 52 is stably installed in the mounting groove 336.

[0059] The first connecting section 521 and the second connecting section 522 can also be a separate structure, which facilitates the replacement of the first connecting section 521 after wear, and also facilitates the replacement of the second connecting section 522 after wear. When the first connecting section 521 and the second connecting section 522 are separate structures, during installation, the connecting part 511 is first rotatably fitted onto the first connecting section 521, and then the second connecting section 522 is connected to the first connecting section 521 to form a stepped surface. The connecting part 511 is then brought into contact with the stepped surface. Then, the first connecting section 521 and the second connecting section 522 are inserted into the mounting groove 336 until the connecting part 511 abuts against the stop part 337. Finally, the second connecting section 522 is fixed to the groove wall of the mounting groove 336 with adhesive, thereby achieving stable installation of the rotating shaft 52 in the mounting groove 336.

[0060] In one embodiment, please refer to the reference Figure 7 and Figure 8 The drive structure 40 includes a drive gear 41 and a transmission gear 42. The drive gear 41 meshes with the transmission gear 42, and the transmission gear 42 meshes with the rotating part 321.

[0061] The drive gear 41 meshes with the transmission gear 42. The rotation of the drive gear 41 drives the transmission gear 42 to rotate. The transmission gear 42 meshes with the rotating part 321, and the rotation of the transmission gear 42 drives the rotating part 321 to rotate. The rotating part 321 drives the coil spring 31 to rotate, and the coil spring 31 drives the battery cover 70 to move in the left-right direction. This achieves the effect that the drive structure 40 drives the second transmission assembly 30 to move the battery cover 70 in the left-right direction. Furthermore, gear meshing transmission has the advantages of stable transmission and high transmission accuracy.

[0062] In one embodiment, please refer to the reference Figure 7 and Figure 8 The first transmission assembly 20 also includes a first transmission component 21 and a second transmission component 22. The first transmission component 21 includes a transmission shaft 211, a connecting gear 212 and a first bevel gear 213. Both the connecting gear 212 and the first bevel gear 213 are connected to the transmission shaft 211. The connecting gear 212 meshes with the drive gear 41. The second transmission component 22 includes a screw 221 and a second bevel gear 222 connected to each other. The second bevel gear 222 meshes with the first bevel gear 213. The screw 221 is threadedly connected to the battery holder 23. The battery holder 23 has a mounting cavity, and the battery body 60 is detachably disposed in the mounting cavity.

[0063] A drive shaft 211 extends in the front-to-back direction. A connecting gear 212 and a first bevel gear 213 are spaced apart in the front-to-back direction and both are connected to the drive shaft 211. The connecting gear 212 meshes with a drive gear 41, and the rotation of the drive gear 41 drives the connecting gear 212 to rotate. The connecting gear 212 is coaxial with the first bevel gear 213, and the rotation of the connecting gear 212 drives the first bevel gear 213 to rotate. The first bevel gear 213 meshes with a second bevel gear 222, and the first bevel gear 213 drives the second bevel gear 222 to rotate. The second bevel gear 222 is connected to a screw 221, which extends in the vertical direction, and the second bevel gear 222 drives the screw 221 to rotate. The screw 221 is threadedly connected to the battery holder 23. Rotation of the screw 221 causes the battery holder 23 to move vertically. The battery holder 23 has a mounting cavity, in which the battery body 60 is detachably mounted.

[0065] The drive unit 411 is connected to the knob unit 412. The drive gear 41 meshes with the transmission gear 42 and the connecting gear 212 through the drive unit 411, thereby enabling the drive structure 40 to drive the transmission gear 42 and the connecting gear 212 to rotate. The knob unit 412 extends out of the strap 10, making it convenient for the operator to turn the knob unit 412, thereby enabling the drive gear 41 to rotate. The knob unit 412 makes it easier for the operator to replace the battery 60.

[0066] In one embodiment, please refer to the reference Figure 7 and Figure 8 The battery body 60 is provided with a guide protrusion 61, which extends along the second direction. The battery holder 23 is provided with a guide groove 231, and the guide protrusion 61 can slide relative to the groove wall of the guide groove 231.

[0067] A guide protrusion 61 is provided on the side wall of the battery body 60, extending vertically. A guide groove 231 is provided on the top of the battery holder 23, extending vertically, and its shape matches that of the guide protrusion 61. The guide protrusion 61 can slide vertically relative to the wall of the guide groove 231. The battery body 60 slides upward relative to the wall of the guide groove 231 to detach from the battery holder 23. The battery body 60 slides downward relative to the wall of the guide groove 231 to rotate into the battery holder 23. The cooperation between the guide protrusion 61 and the guide groove 231 makes the disassembly and installation of the battery body 60 more convenient. Furthermore, the cooperation between the guide protrusion 61 and the guide groove 231 prevents the battery body 60 from shaking within the battery holder 23.
