For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0025] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0026] In related technologies, the batteries of various forms of wearable devices such as augmented reality (AR), virtual reality (VR) and mixed reality (MR) are large, resulting in a heavier overall weight of the device. When the wearer wears a VR device, the head needs to bear a heavy load for a long time, which increases the burden on the wearer's head and affects the wearer's use effect and experience.

[0027] The battery device provided in the embodiment of the present application can be separated from the head-mounted body, and the head-mounted body no longer bears the weight of the battery, thereby reducing the weight of the head-mounted body, reducing the fatigue of the wearer when wearing it, and enhancing the viewing effect. This design makes the head-mounted device lighter, and the wearer can wear it more comfortably for a long time, improving the wearer's user experience.

[0028] Reference Figures 1 to 3 , an embodiment of the present application provides a battery device, the battery device comprising: A housing 1, wherein a battery 11 and a circuit board 12 are disposed in the housing 1, wherein the battery 11 is electrically connected to the circuit board 12, and the circuit board 12 is used for signal connection with the head-mounted body; The storage member 2 has an operating section 21 and a winding section 22. The storage member 2 is connected to the housing 1, and the operating section 21 is located outside the housing 1, and the winding section 22 is located inside the housing 1; The flexible wearing piece 3 has one end connected to the shell 1 and the other end connected to the winding section 22. The winding section 22 can store at least part of the flexible wearing piece 3 when rotating.

[0029] In the above embodiment, the battery 11, as the power source of the battery device, can provide power support for the entire battery device and the head-mounted body connected to the battery device signal, and is the power source for the normal operation of the head-mounted display device. The circuit board 12, as a control component connected to the head-mounted body signal, can control the screen display of the head-mounted body and realize the coordinated work of the battery device and the head-mounted body. For example, through the information exchange between the battery device and the head-mounted body, the screen switching, screen brightness adjustment and other instructions of the head-mounted body can be controlled.

[0030] At the same time, the battery 11 can stably supply power to the circuit board 12, so that various electronic components on the circuit board 12 can work normally. The circuit board 12 can also monitor and manage the charging status, power and other information of the battery 11, ensuring stable power transmission and signal interaction between the battery 11 and the circuit board 12, and improving the reliability and stability of the entire battery device.

[0031] The embodiment of the present application provides a basic guarantee for the separation design of the battery device and the head-mounted body and the realization of the overall function by separating the battery device from the head-mounted body and the VR body. This means that when the head-mounted display device is used, only the head-mounted body can be worn on the head, and the battery device can be worn on the wearer's arm or waist. The head-mounted body no longer bears the weight of components such as the battery 11 and the circuit board 12. While ensuring that the head-mounted display device is in a wearing state as a whole, the purpose of reducing the weight of the head is achieved, reducing the wearer's head fatigue, and enhancing the wearer's viewing effect.

[0032] See also Figure 3The operation section 21 is located outside the housing 1 and can provide an operation interface for the wearer. The wearer can control the rotation of the winding section 22 by operating the operation section 21, thereby realizing the storage and release of the flexible wearing member 3. The winding section 22 serves as a storage component for the flexible wearing member 3. The flexible wearing member 3 can be wound on the winding section 22 by rotating itself to realize the length adjustment of the flexible wearing member 3. The wearer can conveniently adjust the length of the flexible wearing member 3 according to his or her needs, thereby improving the wearing comfort and flexibility.

[0033] At the same time, the segmented design of the operating section 21 and the winding section 22 also makes the operation more convenient. The wearer does not need to directly contact the flexible wearing member 3, thereby avoiding the situation where the flexible wearing member 3 is damaged due to improper operation.

[0034] In one embodiment, the operating section 21 and the winding section 22 may be integrally formed to ensure consistency and stability in the rotation of the winding section 22 driven by the operating section 21 .

[0035] In the above embodiment, the storage member 2 is connected to the housing 1, so that the storage member 2 and the battery device form a whole, which is convenient for carrying and use. The winding section 22 is located in the housing 1, which can prevent the flexible wearable member 3 from being damaged during the storage process. By rotating the storage member 2 to different angles, the wearing length of the flexible wearable member 3 can be flexibly adjusted.

[0036] In the above embodiment, the flexible wearing member 3 is a component for connecting the battery device and the wearer, one end of which is fixed to the housing 1, and the other end of which is adjusted in length by the winding section 22. The wearer can rotate the winding section 22 of the storage member 2 to wind or release the flexible wearing member 3, thereby wearing the battery device on the arm, waist or other parts, so that the battery device can be conveniently worn on the wearer, improving the convenience of use.

[0037] At the same time, since the flexible wearing piece 3 has a certain flexibility, it can adapt to the wearing positions and wearing habits of different wearers, thereby improving the wearing comfort.

[0038] When the wearer does not need to use the battery device, the winding section 22 can be rotated by the operating section 21 to wind the flexible wearing member 3 on the winding section 22, thereby reducing the overall volume of the battery device and making it easier to carry and store. When the battery device needs to be used, the winding section 22 is rotated in the opposite direction to release the flexible wearing member 3 to achieve a suitable wearing length.

[0039] In one embodiment, see Figures 1 to 3 The housing 1 includes an outer shell 14 and a cover 15 , and the cover 15 is connected to the outer shell 14 to form a receiving space, so that the battery 11 , the circuit board 12 and a part of the storage member 2 are arranged in the receiving space.

[0040] In the above embodiment, the cover body 15 can be fixed to the opening on one side of the outer shell 14 by bonding or welding to ensure the sealing of the accommodating space; or the cover body 15 can be fixed to the opening on one side of the outer shell 14 by a detachable method such as screws or pins to facilitate the disassembly and installation of the battery 11, circuit board 12 and storage component 2.

[0041] In some embodiments, see Figure 1 and Figure 3 The operating section 21 is provided with one of the limiting groove 23 and the convex rib 24, and the housing 1 is provided with the other of the limiting groove 23 and the convex rib 24; The storage member 2 is movably arranged in the shell 1 along the first direction and has a fixed state and a rotating state. When the storage member 2 is in the fixed state, the rib 24 and the limiting groove 23 are snap-fitted; when the storage member 2 is in the rotating state, the rib 24 and the limiting groove 23 are disengaged.

[0042] In the above embodiment, by arranging the limiting groove 23 and the convex rib 24 on the operating section 21 and the housing 1 respectively, the storage member 2 can be circumferentially fixed on the housing 1 when the storage member 2 does not need to rotate relative to the housing 1 .

[0043] In addition, other auxiliary structures are arranged around the limiting groove 23 or the convex rib 24 to achieve functions such as waterproofing, dustproofing, and shock absorption, and will not affect the matching function of the limiting groove 23 and the convex rib 24.

[0044] In the above embodiment, the battery device has a length dimension, a width dimension and a height dimension, the first direction may be the Z direction in the figure, the length dimension of the battery device is its dimension in the X direction, the width dimension of the battery device is its dimension in the Y direction, and the height dimension of the battery device is its dimension in the Z direction. The storage member 2 moves relative to the housing 1 along the first direction, so that the storage member 2 can be switched between a fixed state and a rotating state, thereby realizing a rapid switching of the functional state of the storage member 2. The wearer can switch the storage member 2 from a fixed state to a rotating state as needed, and only needs to disengage the rib 24 and the limit groove 23, thereby improving the versatility and adaptability of the battery device.

[0045] In the above embodiment, the snap fit between the rib 24 and the limiting groove 23 provides stable positioning for the storage member 2. When the storage member 2 is in a fixed state, the snap fit can prevent the storage member 2 from rotating in the housing 1, ensuring that the storage member 2 can be accurately fixed in a predetermined position, thereby enhancing the connection reliability between the storage member 2 and the housing 1.

[0046] In the above embodiment, the disengagement of the rib 24 and the limiting groove 23 provides the storage member 2 with a degree of freedom of rotation. In the rotating state, the storage member 2 can freely rotate circumferentially relative to the housing 1 without being restricted by the snap fit, so that the wearer can flexibly adjust the rotation angle of the storage member 2 according to actual needs, and facilitate the length adjustment of the flexible wearable member 3.

[0047] In some embodiments, see Figure 1 and Figure 3 A plurality of limiting grooves 23 are arranged at intervals on the circumference of the operating section 21 , and the storage member 2 is penetrated in the shell 1 through an assembly hole. A plurality of convex ribs 24 are arranged on the edge of the assembly hole, and the plurality of convex ribs 24 are correspondingly engaged with the plurality of limiting grooves 23 .

[0048] In the above embodiment, a plurality of limit grooves 23 are arranged at circumferential intervals on the operating section 21, providing a plurality of precise positioning points for the cooperation between the storage member 2 and the shell 1, and being able to more accurately determine the position of the storage member 2 in the shell 1, thereby reducing problems such as shaking and offset of the storage member 2 caused by inaccurate positioning, thereby improving the overall stability and reliability of the battery device.

[0049] Furthermore, the plurality of limit grooves 23 can disperse the external force borne by the storage member 2. When the storage member 2 is subjected to external force, the plurality of limit grooves 23 jointly bear the force, thereby preventing a single limit point from being damaged due to excessive force.

[0050] See also Figure 1 The plurality of convex ribs 24 are correspondingly engaged with the limiting grooves 23, thereby increasing the connection points between the receiving member 2 and the housing 1, and making the limiting between the receiving member 2 and the housing 1 reliable.

[0051] In one embodiment, a plurality of limiting grooves 23 may be arranged at equal intervals on the circumference of the operating section 21 , and a plurality of convex ribs 24 may also be arranged at equal intervals on the edge of the assembly hole to facilitate the corresponding cooperation between the convex ribs 24 and the limiting grooves 23 .

[0052] In addition, the provision of multiple limiting grooves 23 can increase the roughness of the operating section 21, making it easier for the wearer to rotate the storage component 2.

[0053] In some embodiments, see Figures 3 to 5 The battery device further includes a limiter 4, which is disposed in the housing 1 and has a limiter cavity 41, and an anti-slip portion 221 is disposed at one end of the winding section 22 away from the operating section 21; When the storage member 2 is switched from the rotating state to the fixed state, the anti-slip portion 221 is embedded and matched with the limiting cavity 41 in the first direction.

[0054] In the above embodiment, the anti-detachment portion 221 can prevent the storage member 2 from detaching from the housing. When the storage member 2 is in a fixed state, the cooperation between the limiting groove 23 and the convex rib 24 can only limit the circumferential rotation of the storage member 2, and the storage member 2 can still move in the first direction. If there is no restriction of the anti-detachment portion 221, the winding section 22 can easily slide off the housing 1, resulting in the battery device being unable to be worn normally.

[0055] When the storage member 2 switches from the rotating state to the fixed state, the anti-slip portion 221 and the limiting cavity 41 are embedded in the first direction to provide a stable fixing point for the storage member 2, so that the storage member 2 will not move in the first direction in the fixed state, thereby improving the stability of the state switching. In addition, the anti-slip portion 221 and the limiting cavity 41 in the first direction can also guide the storage member 2.

[0056] In some embodiments, see Figure 4 and Figure 5 The opening edge of the limiting cavity 41 is provided with a plurality of spaced flexible teeth 42 , and the area surrounded by the plurality of flexible teeth 42 is smaller than the area of ​​the anti-slip portion 221 .

[0057] In the above embodiment, the flexible teeth 42 have a certain flexibility, and when the anti-slip portion 221 enters or leaves the limiting cavity 41, the flexible teeth 42 will be elastically deformed. This elastic deformation can play a buffering role, reducing the direct collision and friction between the anti-slip portion 221 and the opening edge of the limiting cavity 41, thereby reducing the wear of the anti-slip portion 221 and the limiting cavity 41.

[0058] A plurality of flexible teeth 42 arranged at intervals form a tooth-shaped buckle at the opening edge of the limiting cavity 41. The winding section 22 is inserted downward into the tooth-shaped buckle along the first direction to limit the movement of the storage component 2 in the first direction. The flexible tooth-shaped buckle also facilitates the storage component 2 to be pulled out upward, thereby facilitating the adjustment of the length of the flexible wearing component 3.

[0059] Since the area surrounded by the multiple flexible teeth 42 is smaller than the area of ​​the anti-slip portion 221, when the anti-slip portion 221 begins to slip out of the limiting cavity 41, the flexible teeth 42 will block the anti-slip portion 221. This blocking effect prevents the anti-slip portion 221 from slipping out of the limiting cavity 41 easily, thus achieving the limiting function.

[0060] When the anti-slip part 221 is inserted into the limiting cavity 41, the flexible teeth 42 will be elastically deformed under the pressure of the anti-slip part 221, and after deformation, a reverse elastic force will be generated to tightly clamp the anti-slip part 221 in the limiting cavity 41. This self-locking property makes the anti-slip part 221 more firmly in the limiting cavity 41, further enhancing the reliability of the limiting.

[0061] In some embodiments, see Figure 2 The housing 1 includes a receiving chamber and a storage chamber, and a partition 13 is provided in the receiving chamber to divide the receiving chamber into a battery chamber and a control chamber; The battery 11 is fixed to the battery compartment, the circuit board 12 is detachably connected to the control compartment, and the winding section 22 is located in the storage cavity.

[0062] In the above embodiment, the interior of the housing 1 is divided into a receiving chamber and a storage chamber, so that different functional components can be placed in different zones. This clear zone design makes the internal structure of the battery device clearer and facilitates independent operation and maintenance of each functional component.

[0063] See also Figure 2 The partition 13 divides the receiving cavity into a battery compartment and a control compartment, which are used to place the battery 11 and the circuit board 12 respectively. This partition structure can play a certain protective role for the battery 11 and the circuit board 12. For example, when the battery device is impacted by external force, the partition 13 can prevent direct collision between the battery 11 and the circuit board 12, reducing the risk of component damage; and the partition 13 can also be a heat insulation board, which can play a role in heat insulation.

[0064] The winding section 22 may move during operation, such as extending and rotating. Placing the winding section 22 in an independent storage chamber can reduce the interference of the movement of the winding section 22 on other components. For example, the movement of the winding section 22 is prevented from affecting the stability of the battery 11 and the circuit board 12, ensuring the normal operation of the battery device. In a specific embodiment, the partition 13 is fixed to the shell 1 by glue to fix the battery 11 and ensure the stability of the battery 11. The circuit board 12 is fixed to the shell 1 by pan head screws to facilitate the disassembly and assembly of the circuit board 12 while ensuring the installation stability of the circuit board 12.

[0065] In some embodiments, the storage member 2 has a first rotation angle and a second rotation angle; When the storage member 2 is at a first rotation angle, the flexible wearing member 3 has a first wearing length, and when the storage member 2 is at a second rotation angle, the flexible wearing member 3 has a second wearing length, which is smaller than the first wearing length.

[0066] See also Figure 3 , the storage member 2 is pulled upward as shown by the arrow in the figure, so that the storage member 2 switches from the fixed state to Figure 5 In the rotation state, the anti-slip portion is out of the limiting cavity, and the rib 24 is also out of the limiting groove 23 on the operating section. Figure 5 and Figure 7 The figure shows the state where the flexible wearing member 3 is at its longest length. Figure 5 and Figure 6The storage member 2 is rotated clockwise in the direction of the green arrow, and the flexible wearing member 3 is sequentially wound on the winding section 22 to adjust the length of the flexible wearing member 3 from the first wearing length to the second wearing length. After the length of the flexible wearing member 3 is adjusted, the storage member 2 is pressed down along the first direction, the anti-slip portion is snapped into the toothed buckle, and the rib 24 is snapped into the limiting groove 23, and the position of the storage member 2 is fixed.

[0067] In some embodiments, one end of the flexible wearing piece 3 is detachably connected to the shell 1 .

[0068] In the above embodiment, one end of the flexible wearable piece 3 can be detachably connected to the shell 1 by a hook or a buckle. When it needs to be worn for a long time and the hands need to be kept free, the flexible wearable piece 3 can be connected to the shell 1 and the battery device can be worn on the wrist, arm, etc. In some temporary use or when it is not necessary to wear it, one end of the flexible wearable piece 3 can be removed to facilitate the storage of as much of the flexible wearable piece 3 as possible into the winding section 22.

[0069] The embodiment of the present application further provides a head mounted display device, the head mounted display device comprising a head mounted body and the battery device of the first aspect; The circuit board 12 is connected to the head-mounted body by signal.

[0070] In the above embodiment, the battery device of the head mounted display device can be separated from the head mounted body, and the head mounted body no longer bears the weight of the battery, thereby reducing the weight of the head mounted body, reducing fatigue of the wearer when wearing the head mounted device, and enhancing the viewing effect. This design makes the head mounted device lighter, and the wearer can wear it more comfortably for a long time, thereby improving the wearer's use experience.

[0071] Moreover, the circuit board 12, as a control component connected to the head-mounted body signal, can control the screen display of the head-mounted body and realize the coordinated work of the battery device and the head-mounted body. For example, through the information exchange between the battery device and the head-mounted body, the screen switching, screen brightness adjustment and other instructions of the head-mounted body can be controlled.

[0072] In some embodiments, a main board is disposed in the head-mounted body, and the circuit board 12 is connected to the main board signal.

[0073] In the above embodiment, the mainboard, as the core control center of the head-mounted device, can integrate multiple functional modules. By connecting the circuit board 12 with the signal, the control signal of the circuit board 12 can be transmitted to the control system of the head-mounted device, so as to realize the coordinated work of the functions and provide the wearer with a more intelligent and convenient use experience.

[0074] In the above embodiment, the circuit boards 12 with different functions are connected to the main board by signals, so that the functional modules can share data and instructions in real time, thereby improving the overall performance of the device. For example, the main board can work with the circuit board 12 responsible for image processing and the circuit board 12 responsible for motion capture to achieve high-precision image rendering and motion tracking, thereby enhancing the wearer's immersion and interactive experience.

It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application.
