Description

Technical Field

[0001] This application relates to the field of head-mounted display technology, and more particularly to a power supply structure for a head-mounted display device. Background Technology

[0002] With the development of technology, head-mounted display devices are increasingly being used in people's daily lives as an emerging technological product. These head-mounted display devices can include flight goggles, augmented reality (AR) glasses, or virtual reality (VR) glasses, among others.

[0003] In related technologies, head-mounted display devices generally include a power supply structure and a magnetometer. The power supply structure includes a main body and a plug-in component. The main body and one end of the plug-in component are magnetically attached together and electrically connected. The other end of the plug-in component is electrically connected to the power supply, thereby realizing the electrical connection between the main body and the power supply. The magnetometer is set on the main body to detect and track the user's head posture.

[0004] However, due to the presence of the magnetic structure, the spatial positioning accuracy of the magnetometer will be affected, and ultimately the normal use of the head-mounted display device will be affected. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a power supply structure for a head-mounted display device, which ensures the spatial positioning accuracy of the magnetometer, thereby guaranteeing the normal operation of the head-mounted display device.

[0006] This application is achieved through the following technical solution.

[0007] This application provides a power supply structure for a head-mounted display device, including a head-mounted display device body and a connector. The head-mounted display device body has a first magnetic element and a first shielding element, with the first shielding element enclosing the first magnetic element. The connector has a second magnetic element and a second shielding element at its end, with the second shielding element enclosing the second magnetic element. The first and second magnetic elements are magnetically attracted to each other, and the end of the connector is electrically connected to the head-mounted display device body.

[0008] In the technical solution of this application embodiment, the connector is fixed to the head-mounted display device body by the mutual attraction of the first magnetic component and the second magnetic component. Since the first shielding component encloses the first magnetic component, it can weaken the strength of the magnetic field generated by the first magnetic component, thereby reducing the interference of the first magnetic component on the magnetometer. Similarly, since the second shielding component encloses the second magnetic component, it can weaken the strength of the magnetic field generated by the second magnetic component, thereby reducing the interference of the second magnetic component on the magnetometer.

[0009] In this way, this application can not only realize the connection between the head-mounted display device body and the connector, but also reduce the interference of the first magnetic component and the second magnetic component on the magnetometer, thereby ensuring the spatial positioning accuracy of the magnetometer and thus ensuring the normal operation of the head-mounted display device.

[0010] In some embodiments of this application, a first shielding member is connected to the head-mounted display device body. The first shielding member has a first recess, and a first magnetic member is fixed within the first recess to be enclosed by the first shielding member. A second shielding member is connected to the end of a connector. The second shielding member has a second recess, and a second magnetic member is fixed within the second recess to be enclosed by the second shielding member. The slots of the first and second recesses are positioned opposite each other.

[0011] The first recess allows the first shielding component to enclose the first magnetic component, and the second recess allows the second shielding component to enclose the second magnetic component. This facilitates the placement of both the first and second magnetic components. Furthermore, the first and second magnetic components can achieve contact-type magnetic attraction through the slots of the first and second recesses, thereby increasing the strength of the adsorption.

[0012] In some embodiments of this application, the power supply structure for the head-mounted display device further includes at least two first transmission components and at least two second transmission components. The at least two first transmission components are fixed to a first shield and arranged at intervals around the slots of a first recess, and are electrically connected to the head-mounted display device body. The at least two second transmission components are fixed to a second shield and arranged at intervals around the slots of a second recess, and are electrically connected to the ends of connectors. The at least two first transmission components and the at least two second transmission components correspond one-to-one, and the first and second transmission components engage in contact to achieve mutual electrical connection.

[0013] The electrical connection between the head-mounted display device body and the connector is achieved through the contact electrical connection between the first and second transmission components. Thus, when the first and second magnetic components are magnetically attracted, the electrical connection between the head-mounted display device body and the connector can be directly achieved, making setup convenient.

[0014] In some embodiments of this application, the first shielding member includes a first base and a first support portion. The first base has a third recess facing the second recess, and the first base is fixed to the head-mounted display device body. The first support portion is detachably connected to the third recess. Both the first recess and the first transmission member are located on the first support portion.

[0015] By setting the first shielding component into two detachable parts, and by placing the first recess and the first transmission component on the first bearing part, it is easy to disassemble and install the first magnetic component and the first transmission component.

[0016] In some embodiments of this application, the first support portion has at least two first channels, which are arranged at intervals around the slot of the first recess. Each first channel is provided with a first transmission element, which is electrically connected to the head-mounted display device body through the first channel.

[0017] By placing the first transmission component inside the first channel, and since the first channel is located on the first support portion, the first transmission component can be located inside the first support portion, thus avoiding exposure of the first transmission component and ensuring the safety of the electrical connection.

[0018] In some embodiments of this application, the power supply structure for the head-mounted display device further includes a first adapter board, which is fixed between the first support portion and the head-mounted display device body. The first adapter board is electrically connected to the head-mounted display device body, and the first transmission component is electrically connected to the first adapter board through a first channel.

[0019] By setting up a first adapter board, it is possible to facilitate the electrical connection between at least two first transmission components and the head-mounted display device body.

[0020] In some embodiments of this application, the second shielding member includes a second base and a second supporting portion. The second base has an opening facing the first recess, and the second base is fixed to the end of the connector. The second supporting portion is detachably connected to the opening of the second base. The second recess and the second transmission member are both located on the second supporting portion.

[0021] By setting the second shielding member as two detachable parts, and setting the second recess and the second transmission member on the second bearing part, it is easy to disassemble and install the second magnetic member and the second transmission member.

[0022] In some embodiments of this application, the second bearing portion has at least two second channels, which are arranged at intervals around the slot of the second recess. Each second channel is provided with a second transmission member, which is electrically connected to the end of the connector through the second channel.

[0023] By placing the second transmission component inside the second channel, and since the second channel is located on the second carrier, the second transmission component can be located inside the second carrier, thus avoiding exposure of the second transmission component and ensuring the safety of the electrical connection.

[0024] In some embodiments of this application, a first limiting structure is provided on the first shielding member, and a second limiting structure is provided on the second shielding member. The first limiting structure and the second limiting structure cooperate to restrict the relative movement of the first shielding member and the second shielding member.

[0025] The relative movement between the first and second shielding components can be restricted by the cooperation of the first and second limiting structures, thereby improving the connection stability of the first and second shielding components.

[0026] In some embodiments of this application, the second support portion includes a support base and a connecting bracket. The support base is disposed within the opening of the second base, and the second recess and the second channel are both located on the support base. The connecting bracket is connected to the support base and is disposed along the circumference of the first shielding member, and the second limiting structure is disposed on the connecting bracket.

[0027] At the same time, the connecting bracket is arranged along the circumference of the first shielding member, and the second limiting structure is set on the connecting bracket to facilitate the cooperation and connection between the first limiting structure 20 and the second limiting structure.

[0028] In some embodiments of this application, the first limiting structure 20 includes a protrusion, the second limiting structure includes a groove, and the connecting bracket is circumferentially rotatable along the first shield to allow the protrusion to extend into or out of the groove.

[0029] The head-mounted display device body and the connector are limited by the cooperation of the groove and the protrusion. Since the connecting bracket can rotate around the first shielding component, so that the protrusion extends into or out of the groove, by reasonably setting the positions of the first transmission component and the second transmission component, multiple first transmission components and multiple second transmission components can be made to make precise contact and electrical connection with each other when the protrusion extends into the groove.

[0030] In some embodiments of this application, the power supply structure for the head-mounted display device further includes a second adapter plate, which is fixed to the side of the second support portion away from the head-mounted display device body. The second adapter plate is electrically connected to the end of the connector, and the second transmission component is electrically connected to the second adapter plate through a second channel.

[0031] By setting up a second adapter plate, it is possible to facilitate the electrical connection between at least two second transmission components and the connector.

[0032] In some embodiments of this application, the second base has a cavity communicating with the opening of the second base, the second adapter plate is located in the cavity, and the end of the connector extends into the cavity to be electrically connected to the second adapter plate.

[0033] By placing the second adapter plate inside the cavity, the second adapter plate is protected from damage, and the second adapter plate is not exposed to the outside, which can improve the safety of the electrical connection.

[0034] In some embodiments of this application, the two ends of the first transmission element and the second transmission element that are close to each other are elastically connected by electrical contact.

[0035] This ensures the stability of the electrical connection between the first and second transmission components.

[0036] In some embodiments of this application, in a direction perpendicular to the arrangement of the first and second shielding members, the first magnetic member includes a first south magnetic pole and a first north magnetic pole, and the second magnetic member includes a second south magnetic pole and a second north magnetic pole. The first south magnetic pole and the second north magnetic pole are opposite each other and magnetically attracted to each other, and the first north magnetic pole and the second south magnetic pole are opposite each other and magnetically attracted to each other.

[0037] In this way, the precise alignment of the first south magnetic pole with the second north magnetic pole, and the precise alignment of the second south magnetic pole with the first north magnetic pole, helps to achieve the electrical connection between the first and second transmission components.

[0069] The following is a detailed description of this application.

[0070] With the development of technology, head-mounted display devices are becoming increasingly widely used in people's daily lives as a new type of technological product.

[0071] For example, head-mounted display devices may include flight goggles, augmented reality (AR) glasses, or virtual reality (VR) glasses, etc.

[0072] Head-mounted display devices generally include a power supply structure, a display module, an inertial measurement unit (IMU), and a magnetometer. The power supply structure, located on the display module, provides power to enable the display to function properly. The inertial measurement unit and magnetometer, also located on the display module, detect and track the user's head posture, thus ensuring the normal operation of the head-mounted display device.

[0073] In related technologies, the power supply structure of a head-mounted display device generally includes a main body and a plug-in component. The main body is connected to the display module and is electrically connected to the display module. One end of the plug-in component is magnetically attached to the main body and electrically connected. The other end of the plug-in component is electrically connected to the power supply, thereby realizing the electrical connection between the display module and the power supply. A magnetometer and an inertial measurement unit are set on the main body to detect and track the user's head posture.

[0074] However, due to the presence of the magnetic structure, the spatial positioning accuracy of the magnetometer will be affected, and ultimately the normal use of the head-mounted display device will be affected.

[0075] Based on this, such as Figure 1 , Figure 2 As shown, in some embodiments, this application provides a power supply structure 1 for a head-mounted display device, which includes a head-mounted display device body 11 and a connector 14. The head-mounted display device body 11 has a first magnetic element 12 and a first shielding element 13, with the first shielding element 13 enclosing the first magnetic element 12. The end of the connector 14 is provided with a second magnetic element 15 and a second shielding element 16, with the second shielding element 16 enclosing the second magnetic element 15. The first magnetic element 12 and the second magnetic element 15 are magnetically attracted to each other, and the end of the connector 14 is electrically connected to the head-mounted display device body 11.

[0076] It is understood that the head-mounted display device body 11 should be mounted on the display module of the head-mounted display device, and the head-mounted display device body 11 can be electrically connected to the display module.

[0077] It should be explained that the first shielding member 13 may completely or partially enclose the first magnetic member 12. Similarly, the second magnetic member 15 may completely or partially enclose the second magnetic member 15.

[0078] Additionally, the connector 14 may include a first end and a second end, a second magnetic element 15 and a second shielding element 16 are disposed at the first end of the connector 14, the first end of the connector 14 is electrically connected to the head-mounted display device body 11, and the second end of the connector 14 is electrically connected to the power supply.

[0079] For example, the power source can be AC ​​power. Power can be supplied by setting up a socket and plugging the second end of connector 14 into the socket. Alternatively, the second end of connector 14 can be directly plugged into a device such as a host computer, thus enabling both power supply and data transmission.

[0080] Alternatively, the power supply can be a DC power supply. The specific settings can be configured according to your needs.

[0081] In some examples, the first magnetic element 12 may include a permanent magnet or an electromagnet. The second magnetic element 15 may include a permanent magnet or an electromagnet.

[0082] In some examples, the material of the first shield 13 may include one or more of iron, cobalt, nickel, alloys, and soft magnetic materials.

[0083] In some examples, the material of the second shield 16 may include one or more of iron, cobalt, nickel, alloys, and soft magnetic materials.

[0084] With the above configuration, the connector 14 is fixed to the head-mounted display device body 11 by the mutual attraction of the first magnetic element 12 and the second magnetic element 15. Since the first shielding element 13 encloses the first magnetic element 12, it weakens the strength of the magnetic field generated by the first magnetic element 12, thereby reducing the interference of the first magnetic element 12 on the magnetometer. Similarly, since the second shielding element 16 encloses the second magnetic element 15, it weakens the strength of the magnetic field generated by the second magnetic element 15, thereby reducing the interference of the second magnetic element 15 on the magnetometer.

[0085] In this way, this application can not only realize the connection between the head-mounted display device body 11 and the connector 14, but also reduce the interference of the first magnetic component 12 and the second magnetic component 15 on the magnetometer, thereby ensuring the spatial positioning accuracy of the magnetometer and thus ensuring the normal operation of the head-mounted display device.

[0086] The ways in which the first shielding member 13 encloses the first magnetic member 12 and the second shielding member 16 encloses the second magnetic member 15 are varied, and examples are given below.

[0087] In the first possible implementation, such as Figure 3 As shown, the first shielding member 13 is connected to the head-mounted display device body 11. The first shielding member 13 has a first recess 13a, and the first magnetic member 12 is fixed within the first recess 13a to be enclosed by the first shielding member 13. The second shielding member 16 is connected to the end of the connector 14. The second shielding member 16 has a second recess 16a, and the second magnetic member 15 is fixed within the second recess 16a to be enclosed by the second shielding member 16. The slots of the first recess 13a and the second recess 16a are positioned opposite each other.

[0088] In some examples, the first magnetic element 12 is detachably connected to the first shielding element 13, which facilitates the removal of the first magnetic element 12.

[0089] For example, the first magnetic element 12 can be snapped into the first recess 13a. Alternatively, the first magnetic element 12 can be fastened to the first recess 13a with screws.

[0090] In other examples, the first magnetic element 12 and the first shielding element 13 can also be connected in a non-detachable manner, which can ensure the stability of the connection between the first magnetic element 12 and the first shielding element 13.

[0091] For example, the first magnetic component 12 can be welded together with the first shielding component 13.

[0092] Similarly, in some examples, the second magnetic element 15 is detachably connected to the second shielding element 16, which facilitates the removal of the second magnetic element 15.

[0093] For example, the second magnetic element 15 can be snapped into the second recess 16a. Alternatively, the second magnetic element 15 can be fastened to the second recess 16a with screws.

[0094] In other examples, the second magnetic element 15 and the second shielding element 16 can also be non-detachably connected, which can ensure the connection stability of the second magnetic element 15 and the second shielding element 16.

[0095] For example, the second magnetic element 15 can be welded together with the second shielding element 16.

[0096] In some examples, the cross-section of the first recess 13a perpendicular to its depth direction can be a regular shape such as a polygon (e.g., a rectangle, a square, etc.) or a circle. Alternatively, it can be an irregular shape.

[0097] In some examples, the cross-section of the second recess 16a perpendicular to its depth direction can be a regular shape such as a polygon (e.g., a rectangle, a square, etc.) or a circle. Alternatively, it can be an irregular shape.

[0098] In some examples, the first magnetic element 12 can be a regular shape such as a cube or cylinder. Alternatively, it can be an irregular shape.

[0099] In some examples, the second magnetic element 15 can be a regular shape such as a cube or cylinder. Alternatively, it can be an irregular shape.

[0100] In some examples, the first magnetic element 12 is adapted to the first recess 13a, and the second magnetic element 15 is adapted to the second recess 16a. This facilitates the fixation of the first magnetic element 12 and the second magnetic element 15.

[0101] In some examples, the grooves of the first recess 13a and the second recess 16a can be completely opposite to each other. Alternatively, they can be partially opposite to each other.

[0102] In some examples, when the first magnetic element 12 and the second magnetic element 15 are attracted to each other, the plane where the groove of the first recess 13a is located is in contact with the plane where the groove of the second recess 16a is located. In this way, the first shielding element 13 and the second shielding element 16 can be better used to shield the first magnetic element 12 and the second magnetic element 15.

[0103] The first recess 13a encloses the first magnetic element 12, and the second recess 16a encloses the second magnetic element 15. This arrangement facilitates the placement of the first and second magnetic elements 12 and 15. Furthermore, since the first and second magnetic elements 12 and 15 can achieve contact-type magnetic attraction through the slots of the first and second recesses 13a and 16a, the strength of the attraction is also guaranteed.

[0104] In a second possible implementation, a first receiving cavity is provided within the first shielding member 13, and the first magnetic member 12 is disposed within the first receiving cavity. A second receiving cavity is provided within the second shielding member 16, and the second magnetic member 15 is disposed within the second receiving cavity. This allows the first magnetic member 12 to be magnetically attracted to the second magnetic member 15 through the sidewalls of the first shielding member 13 and the second shielding member 16. This ensures the shielding effect of the first shielding member 13 on the first magnetic member 12 and the shielding effect of the second shielding member 16 on the second magnetic member 15, thereby better reducing the influence of the first magnetic member 12 and the second magnetic member 15 on the magnetometer.

[0105] Based on the first possible implementation method mentioned above, such as Figures 4-6 As shown, in some embodiments of this application, the power supply structure 1 for the head-mounted display device further includes at least two first transmission elements 17 and at least two second transmission elements 18. For example... Figure 4 As shown, at least two first transmission elements 17 are fixed to the first shielding element 13 and arranged at intervals around the slot of the first recess 13a. The first transmission elements 17 are electrically connected to the head-mounted display device body 11. Figure 5 As shown, at least two second transmission elements 18 are fixed to the second shielding element 16 and arranged at intervals around the slot of the second recess 16a. The second transmission elements 18 are electrically connected to the ends of the connector 14. Figure 6 As shown, at least two first transmission elements 17 correspond one-to-one with at least two second transmission elements 18, and the first transmission elements 17 and the second transmission elements 18 are in contact with each other to be electrically connected.

[0106] It is understandable that after the first transmission element 17 and the second transmission element 18 are connected by contact, they can not only provide power but also transmit data when needed. The specific number of the first transmission element 17 and the second transmission element 18, as well as their functions, can be set according to requirements.

[0107] The materials of the first transmission element 17 and the second transmission element 18 may include metals, such as copper, aluminum, etc.

[0108] Furthermore, the first transmission member 17 can be cylindrical or sheet-like in shape. The second transmission member 18 can also be cylindrical or sheet-like in shape.

[0109] In some examples, the number of first transmitters 17 can be two, three, four, five, or more.

[0110] In some examples, the number of second transmitters 18 can be two, three, four, five, or more.

[0111] In some examples, there are five first transmission elements 17 and five second transmission elements 18. For example, three first transmission elements 17 and three second transmission elements 18 are in contact to achieve power supply, and another two first transmission elements 17 and two second transmission elements 18 are in contact to achieve data transmission.

[0112] Electrical connection between the head-mounted display device body 11 and the connector 14 is achieved through the contact electrical connection between the first transmission element 17 and the second transmission element 18. By appropriately setting the positions of the first transmission element 17 and the second transmission element 18, the electrical connection between the head-mounted display device body 11 and the connector 14 can be directly achieved while the first magnetic element 12 and the second magnetic element 15 are magnetically attracted, making setup convenient and operation simple. Furthermore, by appropriately setting the number of the first transmission element 17 and the second transmission element 18, not only can the power connection between the head-mounted display device body 11 and the connector 14 be achieved, but data transmission between them can also be realized.

[0113] Of course, in other embodiments, the end of the connector 14 may also make direct contact with the head-mounted display device body 11 to achieve electrical connection.

[0114] In some embodiments of this application, such as Figure 6 As shown, the first shielding member 13 includes a first base 131 and a first support portion 132. The first base 131 has a third recess 131a facing the second recess 16a, and the first base 131 is fixed to the head-mounted display device body 11. The first support portion 132 is detachably connected to the third recess 131a. The first recess 13a and the first transmission member 17 are both located on the first support portion 132.

[0115] In some examples, the first support portion 132 and the first base 131 can be detachably connected by means of snap-fit, screw fastening, or other methods.

[0116] For example, the third recess 131a is adapted to the first support portion 132, and the first support portion 132 abuts against the inner wall surface of the third recess 131a, thereby engaging the first support portion 132 onto the first base 131.

[0117] In some examples, the third recess 131a has a regular shape such as a circle or square in cross-section perpendicular to its groove depth. Alternatively, it can also be an irregular shape.

[0118] By setting the first shield 13 as two detachable parts, the first base 131 and the first support part 132 can be separated. Since the first recess 13a and the first transmission part 17 are both set on the first support part 132, it is convenient to disassemble and install the first magnetic part 12 and the first transmission part 17 as a whole.

[0119] Based on this, the first transmission member 17 can be configured in various ways. For example, the first transmission member 17 can be directly fixed on the plane where the groove of the first recess 13a on the first support portion 132 is located. Alternatively, a first channel 132a can be formed on the first support portion 132 to place the first transmission member 17 within the first channel 132a.

[0120] In some embodiments, such as Figure 6 As shown, the first support portion 132 has at least two first channels 132a, and the at least two first channels 132a are arranged at intervals around the slot of the first recess 13a. Each first channel 132a is provided with a first transmission element 17, and the first transmission element 17 is electrically connected to the head-mounted display device body 11 through the first channel 132a.

[0121] It is understood that the extension direction of the first channel 132a should form an angle with the plane containing the groove of the first recess 13a. For example, the angle can be 90°, 85°, 95°, 100°, or 80°, etc. In this application, an angle of 90° is used as an example for illustration.

[0122] In some examples, the first transmission element 17 is adapted to the first channel 132a, which makes it easy to fix the first transmission element 17 within the first channel 132a.

[0123] For example, the peripheral wall surface of the first transmission member 17 can be made to abut against the inner wall surface of the first channel 132a, thereby engaging the first transmission member 17 within the first channel 132a.

[0124] In some examples, the number of first channels 132a is the same as the number of first transmission elements 17, and at least two first channels 132a correspond one-to-one with at least two first transmission elements 17.

[0125] By providing a first channel 132a on the first carrier portion 132 and placing the first transmission member 17 within the first channel 132a, the first transmission member 17 can be located inside the first carrier portion 132. The first carrier portion 132 can protect the first transmission member 17 from damage and also prevent the first transmission member 17 from being exposed to the outside, thereby ensuring the safety of the electrical connection.

[0126] In some embodiments of this application, such as Figure 6As shown, the power supply structure 1 for the head-mounted display device also includes a first adapter plate 19. The first adapter plate 19 is fixed between the first support portion 132 and the head-mounted display device body 11. The first adapter plate 19 is electrically connected to the head-mounted display device body 11, and the first transmission component 17 is electrically connected to the first adapter plate 19 through the first channel 132a. By setting the first adapter plate 19, at least two first transmission components 17 can be electrically connected to the first adapter plate 19 simultaneously, thereby facilitating the simultaneous electrical connection of at least two first transmission components 17 to the head-mounted display device body 11.

[0127] In some examples, the first adapter plate 19 is fixed to the outside of the third recess 131a, and the first adapter plate 19 is located between the first base 131 and the head-mounted display device body 11.

[0128] In this case, in order to achieve electrical connection between the first adapter plate 19 and the first transmission component 17, a first through hole can be opened on the bottom wall of the first base 131, so that the end of the first transmission component 17 away from the second transmission component 18 is electrically connected to the first adapter plate 19 through the first through hole.

[0129] In other examples, the first adapter plate 19 is fixed within the third recess 131a and is located between the first support portion 132 and the bottom of the groove of the third recess 131a.

[0130] In this case, in order to achieve electrical connection between the first adapter plate 19 and the head-mounted display device body 11, a second through hole can be opened on the bottom wall of the first base 131 so that the first adapter plate 19 can be electrically connected to the head-mounted display device body 11 through the second through hole.

[0131] The second shielding member 16 is configured similarly to the first shielding member 13. The structure of the second shielding member 16 will be described in detail below.

[0132] In some embodiments, such as Figure 6 As shown, the second shielding member 16 includes a second base 161 and a second supporting portion 162. The second base 161 has an opening 161a facing the first recess 13a, and the second base 161 is fixed to the end of the connector 14. The second supporting portion 162 is detachably connected to the opening 161a of the second base 161. The second recess 16a and the second transmission member 18 are both located on the second supporting portion 162.

[0133] In some examples, the second support portion 162 and the second base 161 can be detachably connected by means of snap-fit, screw fastening, or other methods.

[0134] By setting the second shield 16 as two detachable parts, the second base 161 and the second support part 162 can be separated. Since the second recess 16a and the second transmission part 18 are both set on the second support part 162, it is convenient to disassemble and install the second magnetic part 15 and the second transmission part 18 as a whole.

[0135] Based on this, the second transmission member 18 can be configured in various ways. For example, the second transmission member 18 can be directly fixed on the plane where the opening 161a is located on the second support portion 162. Alternatively, a second channel 162a can be opened on the second support portion 162 to house the second transmission member 18 within the second channel 162a.

[0136] In some embodiments, such as Figure 6 As shown, the second bearing portion 162 has at least two second channels 162a, which are arranged at intervals around the slot of the second recess 16a. Each second channel 162a is provided with a second transmission member 18, which is electrically connected to the end of the connector 14 through the second channel 162a.

[0137] It is understood that the extension direction of the second channel 162a should form an angle with the plane containing the groove of the second recess 16a. For example, the angle can be 90°, 85°, 95°, 100°, or 80°, etc. In this application, an angle of 90° is used as an example for illustration.

[0138] In some examples, the second transmission element 18 is adapted to the second channel 162a, which makes it easy to fix the second transmission element 18 within the second channel 162a.

[0139] For example, the peripheral wall surface of the second transmission member 18 can be made to abut against the inner wall surface of the second channel 162a, thereby engaging the second transmission member 18 within the second channel 162a.

[0140] In some examples, the number of second channels 162a is the same as the number of second transmission elements 18, and at least two second channels 162a correspond one-to-one with at least two second transmission elements 18.

[0141] By providing a second channel 162a on the second carrier portion 162 and placing the second transmission member 18 within the second channel 162a, the second transmission member 18 can be located inside the second carrier portion 162. The second carrier portion 162 can protect the second transmission member 18 from damage and also prevent the second transmission member 18 from being exposed to the outside, thereby ensuring the safety of the electrical connection.

[0142] In some embodiments, such as Figure 6As shown, the first support portion 132 has at least two first channels 132a, which are arranged at intervals around the slot of the first recess 13a. Each first channel 132a contains a first transmission element 17, which is electrically connected to the head-mounted display device body 11 through the first channel 132a. The second support portion 162 has at least two second channels 162a, which are arranged at intervals around the slot of the second recess 16a. Each second channel 162a contains a second transmission element 18, which is electrically connected to the end of the connector 14 through the second channel 162a.

[0143] In this way, neither the first transmission element 17 nor the second transmission element 18 is exposed to the outside, ensuring the stability of their electrical connection. Furthermore, since the two ends of the first channel 132a and the second channel 162a are located on the plane where the slot of the first recess 13a and the slot of the second recess 16a are respectively located, the electrical connection between the first transmission element 17 and the second transmission element 18 can be achieved simultaneously when the first magnetic element 12 and the second magnetic element 15 are attracted to each other, facilitating practical operation.

[0144] In some embodiments of this application, such as Figure 6 As shown, the power supply structure 1 for the head-mounted display device also includes a second adapter plate 22, which is fixed to the side of the second support portion 162 away from the head-mounted display device body 11. The second adapter plate 22 is electrically connected to the end of the connector 14, and the second transmission component 18 is electrically connected to the second adapter plate 22 through the second channel 162a. By providing the second adapter plate 22, at least two second transmission components 18 can be electrically connected to the second adapter plate 22 simultaneously, thereby facilitating the simultaneous electrical connection of at least two second transmission components 18 to the connector 14 and simplifying installation.

[0145] In some examples, the second adapter plate 22 is fixed to the outside of the second base 161. In this case, in order to achieve electrical connection between the second adapter plate 22 and the second transmission component 18, a third through hole can be opened on the bottom wall of the second base 161, so that the second transmission component 18 can be electrically connected to the second adapter plate 22 through the third through hole.

[0146] Alternatively, in some embodiments of this application, such as Figure 6 As shown, the second base 161 has a cavity 161b communicating with the opening 161a of the second base 161. The second adapter plate 22 is located in the cavity 161b. The end of the connector 14 extends into the cavity 161b to be electrically connected to the second adapter plate 22.

[0147] By placing the second adapter plate 22 inside the cavity 161b, the second adapter plate 22 can be protected from damage, and the second adapter plate 22 can be prevented from being exposed to the outside, thereby improving the safety of the electrical connection.

[0148] In order to ensure the connection stability between the first shielding component 13 and the second shielding component 16, in addition to utilizing the mutual attraction between the first magnetic component 12 and the second magnetic component 15, a first limiting structure 20 is provided on the first shielding component 13 and a second limiting structure 21 is provided on the second shielding component 16.

[0149] Specifically, in some embodiments, such as Figure 6 As shown, the first shielding member 13 is provided with a first limiting structure 20, and the second shielding member 16 is provided with a second limiting structure 21. The first limiting structure 20 and the second limiting structure 21 cooperate to restrict the relative movement of the first shielding member 13 and the second shielding member 16.

[0150] It should be explained that the first limiting structure 20 and the second limiting structure 21 cooperate to restrict the relative movement of the first shield 13 and the second shield 16, mainly to restrict the first shield 13 from moving away from the second shield 16.

[0151] With the above settings, the cooperation of the first limiting structure 20 and the second limiting structure 21 can restrict the relative movement of the first shield 13 and the second shield 16, thereby improving the connection stability of the first shield 13 and the second shield 16, and thus improving the connection stability of the electrical connection between the first transmission component 17 and the second transmission component 18, ensuring the normal operation of the head-mounted display device.

[0152] In some embodiments, such as Figure 6 As shown, the second support portion 162 includes a support base 1621 and a connecting bracket 1622. The support base 1621 is disposed within the opening 161a of the second base 161, and the second recess 16a and the second channel 162a are both located on the support base 1621. The connecting bracket 1622 is connected to the support base 1621 and is disposed along the circumference of the first shield 13. The second limiting structure 21 is disposed on the connecting bracket 1622.

[0153] In some examples, such as Figure 6As shown, a first protruding structure 1611 is provided on the inner wall of the opening 161a of the second base 161. The first protruding structure 1611 is arranged around the opening 161a of the second base 161. A second protruding structure 16221 is provided on the connecting bracket 1622. The second protruding structure 16221 is located on the side of the first protruding structure 1611 away from the first shielding member 13 and abuts against the first protruding structure 1611. By providing the first protruding structure 1611 and the second protruding structure 16221, the positioning and installation of the connecting bracket 1622 and the second base 161 can be facilitated.

[0154] By mounting the second limiting structure 21 on the connecting bracket 1622, and since the connecting bracket 1622 is arranged circumferentially along the first shield 13, the first limiting structure 20 and the second limiting structure 21 can be easily connected. Furthermore, by making the connecting bracket 1622 and the carrier 1621 detachable, the overall arrangement of the second magnetic component 15 and the second transmission component 18, as well as the arrangement of the second limiting structure 21, can be facilitated.

[0155] Based on this, such as Figures 6-8 As shown, in some embodiments, the first limiting structure 20 includes a protrusion 201, the second limiting structure 21 includes a groove 211, and the connecting bracket 1622 is rotatable along the circumference of the first shield 13 so that the protrusion 201 extends into or out of the groove 211.

[0156] In some examples, the groove 211 is an inverted "L" shape. The groove 211 includes a first groove segment 2111 and a second groove segment 2112. The first groove segment 2111 extends along the arrangement direction of the first shield 13 and the second shield 16. The second groove segment 2112 is connected to one end of the first groove segment 2111 near the second adapter plate 22 and communicates with the first groove segment 2111. The second groove segment 2112 extends circumferentially along the first shield 13.

[0157] In this way, during the process of extending the protrusion 201 into the groove 211, the protrusion 201 first moves along the end of the first groove segment 2111 away from the second adapter plate 22, until it approaches the end of the second adapter plate 22, and then moves along the second groove segment 2112 to reach the end of the second groove segment 2112. At this time, the multiple first transmission elements 17 and the multiple second transmission elements 18 are in electrical contact with each other. During the process of extending the protrusion 201 out of the groove 211, the protrusion 201 first moves along the second groove segment 2112 to reach the end of the first groove segment 2111 near the second adapter plate 22, and then moves along the first groove segment 2111, and finally slides out of the first groove segment 2111 from the end of the first groove segment 2111 away from the second adapter plate 22. By setting the first groove segment 2111 and the second groove segment 2112, the first groove segment 2111 and the second groove segment 2112 guide the movement of the protrusion 201, and the second groove segment 2112 also restricts the movement of the protrusion 201 along the extension direction of the first groove segment 2111, thereby improving the connection stability between the first shield 13 and the second shield 16.

[0158] In some examples, the first limiting structure 20 and the second limiting structure 21 may be located between the connecting bracket 1622 and the first shield 13, thus facilitating the protrusion 201 to extend into or out of the groove 211. Furthermore, when the first shield 13 includes a first base 131 and a first support portion 132, the first limiting structure 20 and the second limiting structure 21 are located between the first base 131 and the connecting bracket 1622.

[0159] The head-mounted display device body 11 and the connector 14 are positioned by the cooperation of the groove 211 and the protrusion 201. Since the connecting bracket 1622 can rotate around the first shield 13, the protrusion 201 can extend into or out of the groove 211. Therefore, by reasonably setting the positions of the first transmission member 17 and the second transmission member 18, when the protrusion 201 extends into the groove 211, the multiple first transmission members 17 and the multiple second transmission members 18 can be in contact with each other and electrically connected, which facilitates user operation.

[0160] Of course, in other examples, the first limiting structure 20 may include a groove 211 and the second limiting structure 21 may include a protrusion 201.

[0161] In other embodiments, the first limiting structure 20 may include a buckle, and the second limiting structure 21 may include a locking hole, such that the buckle is engaged in the locking hole, or the buckle extends out of the locking hole.

[0162] In some embodiments of this application, such as Figure 6As shown, the two ends of the first transmission element 17 and the second transmission element 18 that are close to each other are elastically connected. In this way, when the first magnetic element 12 and the second magnetic element 15 attract each other, the ends of the first transmission element 17 and the second transmission element 18 that are close to each other will be elastically squeezed and contacted together, which can ensure the stability of the end contact between the first transmission element 17 and the second transmission element 18, thereby ensuring the stability of the electrical connection between them.

[0163] In some examples, the first transmission element 17 includes a first spring pin, and the second transmission element 18 includes a first flat pin. The elastic end of the first spring pin is electrically connected to the horizontal end of the first flat pin by compression.

[0164] Alternatively, the first transmission member 17 includes a first spring pin, and the second transmission member 18 includes a second spring pin. The elastic end of the first spring pin and the elastic end of the second spring pin are electrically connected by compression.

[0165] Alternatively, the first transmission member 17 includes a second flat needle, and the second transmission member 18 includes a second spring needle. The elastic end of the second spring needle is electrically connected to the horizontal end of the second flat needle by compression.

[0166] Since at least two of the first transmission element 17 and the second transmission element 18 are provided, alignment is required when making contact electrical connections between the two.

[0167] To facilitate the positioning of the first transmission element 17 and the second transmission element 18, such as Figure 3 As shown, in some embodiments, in a direction perpendicular to the arrangement of the first shielding member 13 and the second shielding member 16, the first magnetic member 12 includes a first south magnetic pole 121 and a first north magnetic pole 122, and the second magnetic member 15 includes a second south magnetic pole 151 and a second north magnetic pole 152. The first south magnetic pole 121 and the second north magnetic pole 152 are opposite to each other and magnetically attracted, and the first north magnetic pole 122 and the second south magnetic pole 151 are opposite to each other and magnetically attracted.

[0168] It is understandable that the shapes of the first south magnetic pole 121 and the first north magnetic pole 122 can be arbitrary, and the shapes of the second south magnetic pole 151 and the second north magnetic pole 152 can be arbitrary.

[0169] This configuration, through the precise alignment of the first south magnetic pole 121 and the second north magnetic pole 152, and the precise alignment of the second south magnetic pole 151 and the first north magnetic pole 121, facilitates the electrical connection between the first transmission component 17 and the second transmission component 18, making it easier for users to operate.

[0170] Specifically, during user operation, the first magnetic component 12 and the second magnetic component 15 are first attracted together. Then, by rotating the second shielding component 16, the second magnetic component 15 is rotated, thereby aligning the first south magnetic pole 121 with the second north magnetic pole 152 and the second south magnetic pole 151 with the first north magnetic pole 121, so as to assist in realizing the contact electrical connection between the first transmission component 17 and the second transmission component 18.

[0171] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
