Description

Technical Field

[0001] This disclosure relates to virtual reality technology, and more specifically, to a VR head-mounted display device. Background Technology

[0002] Virtual Reality (VR) is a technology that uses computer technology to generate simulated environments, allowing users to immerse themselves in a digital space that feels like the real world. VR headsets, as a specific application of VR technology, are devices that provide users with an immersive virtual environment experience and are gradually becoming widely used.

[0003] In related technologies, VR headsets use fans for heat dissipation and filters to prevent dust from entering, thus providing protection. However, after prolonged use, the filters become clogged with dust, affecting the heat dissipation performance of the VR headset. Therefore, a new technical solution is needed to address these issues. Summary of the Invention

[0004] One objective of this invention is to provide a new technical solution for VR head-mounted display devices.

[0005] According to a first aspect of the present invention, a VR head-mounted display device is provided, comprising a head-mounted display device body, an air outlet being provided in the head-mounted display device body, a filter being disposed at the air outlet, a fan being disposed within the head-mounted display device body, and a cleaning assembly being disposed within the head-mounted display device body.

[0006] The cleaning assembly includes a cleaning brush and a first connecting rod. The cleaning brush is located on the outer wall of the head-mounted display device body and is in contact with the filter screen. One end of the first connecting rod is fixedly connected to the cleaning brush, and the other end of the first connecting rod is fixedly connected to the fan. The first connecting rod is used to drive the cleaning brush to rotate when the fan rotates, so as to clean the filter screen.

[0007] Optionally, the cleaning assembly further includes a tapping component, wherein the tapping component is used to tap the cleaning brush when the cleaning brush is rotated to a first specific position.

[0008] Optionally, the cleaning assembly further includes a striking component, wherein the striking component includes an airbag, a pressure chamber, a push rod, and a striking element.

[0009] A portion of the airbag is exposed outside the head-mounted display device body, while the air chamber is located inside the head-mounted display device body. The airbag and the air chamber are connected in communication.

[0010] The push rod is slidably connected to the piston of the air chamber. The head-mounted display device body has a through hole, through which the push rod can pass and contact the striking element disposed on the outer wall of the head-mounted display device body.

[0011] The airbag is used to be squeezed by the cleaning brush when the cleaning brush rotates to the first specific position, so that the gas in the airbag is introduced into the air pressure chamber, thereby driving the push rod to move, and in turn driving the striking element to move, so as to strike the cleaning brush.

[0012] Optionally, the striking element is rotatably connected to the outer wall of the head-mounted display device body, wherein,

[0013] The striking element is rotated by the movement of the push rod to strike the cleaning brush.

[0014] Optionally, the striking element includes a first rotating element, a rotating shaft, and a second rotating element, wherein,

[0015] The rotating shaft is rotatably connected to the outer wall of the head-mounted display device body, and both the first rotating component and the second rotating component are fixedly connected to the rotating shaft.

[0016] The first rotating member is used to generate rotation about the central axis of the rotating shaft when the push rod moves, and to drive the rotating shaft to rotate on its own axis, and to drive the second rotating member to rotate about the central axis of the rotating shaft, so that the second rotating member strikes the cleaning brush.

[0017] Optionally, the striking component further includes a spring, wherein,

[0018] One end of the spring is fixedly connected to the first rotating member, and the other end of the spring is fixedly connected to the outer wall of the head-mounted display device body, and the push rod can pass through the spring.

[0019] The spring is used to be stretched when the first rotating member rotates, and to return to its original state after the second rotating member completes the striking action, so as to drive the first rotating member to move to its original position.

[0020] Optionally, the head-mounted display device body further includes a flow guiding component, wherein,

[0021] The airflow guiding component is located within the head-mounted display device and is rotatable to guide the airflow generated by the fan rotation.

[0022] Optionally, the flow guiding assembly includes a second connecting rod, a compression plate, a force-bearing plate, and a flow guiding plate, wherein,

[0023] The second connecting rod is fixedly connected to the fan, and the extrusion plate is fixedly connected to the second connecting rod.

[0024] The second connecting rod can rotate under the drive of the fan, thereby causing the extrusion plate to rotate. The force plate is used to be squeezed when the extrusion plate rotates to a second specific position, so as to generate rotation around a first direction, thereby causing the guide plate to rotate around the first direction. When the extrusion plate rotates to a third specific position, it is no longer squeezed, so as to generate rotation around a second direction, thereby causing the guide plate to rotate around the second direction, until the guide plate is reset. The first direction and the second direction are opposite.

[0025] Optionally, the flow guiding assembly further includes a torsion spring rod, wherein,

[0026] The torsion spring rod is rotatably connected to the inner wall of the head-mounted display device body, and the force-bearing plate is fixedly connected to the torsion spring rod, and the flow guide plate is fixedly connected to the torsion spring rod.

[0027] Optionally, the VR head-mounted display device further includes a head-mounted display cover and an elastic band, wherein,

[0028] The head-mounted display device cover is movably connected to the head-mounted display device body, and the elastic band is fixedly installed on the head-mounted display device body.

[0029] The VR head-mounted display device disclosed herein can drive the first connecting rod to rotate after the fan is started, thereby driving the cleaning brush to rotate, so that the cleaning brush can clean the filter screen in all directions. This realizes the cleaning of the filter screen during the use of the VR head-mounted display device, avoids the problem of filter screen clogging, and ensures the heat dissipation effect of the VR head-mounted display device.

[0036] Various exemplary embodiments of this specification will now be described in detail with reference to the accompanying drawings.

[0037] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the embodiments of this specification or their application or use.

[0038] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0039] To address the aforementioned technical problems, one embodiment of this disclosure provides a VR head-mounted display device. Figure 1 A partial cross-sectional schematic diagram of a VR head-mounted display device according to an embodiment of the present disclosure is shown. Figure 1 As shown, the VR head-mounted display device includes a head-mounted display device body 1000. The head-mounted display device body 1000 has an air outlet, and a filter 1100 is located at the air outlet. A fan 1200 is installed inside the head-mounted display device body, and a cleaning assembly 1300 is also provided. The cleaning assembly 1300 includes a cleaning brush 1310 and a first connecting rod 1320. The cleaning brush 1310 is located on the outer wall of the head-mounted display device body 1000 and is in contact with the filter 1100. One end of the first connecting rod 1320 is fixedly connected to the cleaning brush 1310, and the other end of the first connecting rod 1320 is fixedly connected to the fan 1200. The first connecting rod 1320 is used to drive the cleaning brush 1310 to rotate when the fan 1200 rotates, so as to clean the filter 1100.

[0040] The cleaning brush 1310 includes bristles. These bristles come into contact with the filter 1100.

[0041] like Figure 1 As shown, one end of the first connecting rod 1320 has a through hole through which the cleaning brush 1310 passes for a fixed connection. One end of the first connecting rod 1320 and the cleaning brush 1310 can also be fixedly connected by any of the following methods: bolt connection, welding, or adhesive bonding. The other end of the first connecting rod 1320 is fixedly connected to the fan 1200. The axis around which the fan 1200 rotates, the axis around which the first connecting rod 1320 rotates, and the axis around which the cleaning brush 1310 rotates are the same axis.

[0042] like Figure 1 As shown, the VR head-mounted display device also includes a head-mounted display cover 2000 and an elastic band 3000. The head-mounted display cover 2000 is movably connected to the head-mounted display device body 1000. The elastic band 3000 is fixedly installed on the head-mounted display device body 1000.

[0043] The VR head-mounted display device provided in this embodiment can drive the first connecting rod to rotate after the fan is started, thereby driving the cleaning brush to rotate so that the cleaning brush can clean the filter screen in all directions. This realizes the cleaning of the filter screen during the use of the VR head-mounted display device, avoids the problem of filter screen being blocked, and ensures the heat dissipation effect of the VR head-mounted display device.

[0044] In some embodiments, the cleaning assembly 1300 further includes a tapping member 1330. The tapping member 1330 is used to tap the cleaning brush 1310 when the cleaning brush 1310 rotates to a first specific position. That is, when the cleaning brush 1310 is not rotated to the first specific position, the tapping member 1330 is in its original position; when the cleaning brush 1310 is not rotated to the first specific position, the tapping member 1330 moves to the first specific position and taps the cleaning brush 1310 to clean it.

[0045] In some embodiments, such as Figure 2 As shown, the cleaning assembly 1300 also includes a striking component 1330. The striking component 1330 includes an airbag 1331, a pressure chamber 1332, a push rod 1333, and a striking element 1334.

[0046] like Figure 2 As shown, a portion of the airbag 1331 is exposed outside the head-mounted display device body 1000, while the air chamber 1332 is located inside the head-mounted display device body 1000. The airbag 1331 and the air chamber 1332 are connected. The push rod 1333 is slidably connected to the piston of the air chamber 1332. The head-mounted display device body 1000 has a through hole through which the push rod 1333 can pass and contact the striking element 1334 disposed on the outer wall of the head-mounted display device body 1000. When the cleaning brush 1310 rotates to a first specific position, the airbag 1331 is squeezed by the cleaning brush 1310, causing the gas inside the airbag 1331 to enter the air chamber 1332, thereby driving the push rod 1333 to move, which in turn drives the striking element 1334 to move and strike the cleaning brush 1310.

[0047] like Figure 2 As shown, the head-mounted display device body 1000 has a through hole. Part of the airbag 1331 is located in the through hole, and the other part is exposed outside the head-mounted display device body 1000.

[0048] When the cleaning brush 1310 rotates to the first specific position, the air bladder 1331 is compressed, allowing gas from the air bladder 1331 to enter the pressure chamber 1332. This increases the air pressure in the pressure chamber 1332, causing the piston to move. This, in turn, moves the push rod 1333 away from the pressure chamber, thereby causing the striking element 1334 to move and strike the cleaning brush 1310. When the cleaning brush 1310 continues to rotate, the air bladder 1331 is no longer compressed, allowing gas from the pressure chamber 1332 to enter. This decreases the air pressure in the pressure chamber 1332, causing the piston to move in the opposite direction. This, in turn, moves the push rod 1333 closer to the pressure chamber, and the striking element 1334 returns to its original position. It should be noted that the striking element 1334 can return to its original position using the reaction force from the striking of the cleaning brush 1310, or it can be achieved using other external forces.

[0049] In some embodiments, the striking member 1334 is rotatably connected to the outer wall of the head-mounted display device body 1000. The striking member 1334 is rotated under the action of the push rod 1333 to strike the cleaning brush 1310.

[0050] like Figure 2 As shown, the striking component 1334 includes a first rotating component 1334a, a rotating shaft 1334b, and a second rotating component 1334c. The rotating shaft 1334b is rotatably connected to the outer wall of the head-mounted display device body 1000, and both the first rotating component 1334a and the second rotating component 1334c are fixedly connected to the rotating shaft 1334b. The first rotating component 1334a rotates about the central axis of the rotating shaft 1334b when the push rod 1333 moves, causing the rotating shaft 1334b to rotate on its own axis, and also causing the second rotating component 1334c to rotate about the central axis of the rotating shaft, so that the second rotating component 1334c strikes the cleaning brush. The axis around which the first rotating component 1334a rotates, the axis around which the rotating shaft 1334b rotates, and the axis around which the second rotating component 1334c rotates are the same axis.

[0051] In some embodiments, in order to enable the striking element to return to its original state more quickly and accurately after the striking action is completed, such as... Figure 2As shown, the striking component 1330 also includes a spring 1335. One end of the spring 1335 is fixedly connected to the first rotating member 1334a, and the other end of the spring 1335 is fixedly connected to the outer wall of the head-mounted display device body 1000, and the push rod 1333 can pass through the spring 1335. The spring 1335 is used to be stretched when the first rotating member 1334a rotates, and to return to its original state after the second rotating member 1334c completes the striking action, so as to drive the first rotating member 1334a to move to its original position. Here, the original state is a state in which the spring is neither stretched nor compressed.

[0052] In some embodiments, the head-mounted display device body 1000 further includes a flow guiding component 1400. The flow guiding component 1400 is located within the head-mounted display device body 1000 and is rotatable to guide the airflow generated by the rotation of the fan 1200, thereby improving the heat dissipation effect of the VR head-mounted display device.

[0053] like Figure 3 As shown, the flow guiding assembly 1400 includes a second connecting rod 1410, a pressing plate 1420, a force-bearing plate 1430, and a flow guiding plate 1440.

[0054] The second connecting rod 1410 is fixedly connected to the fan 1200. The extrusion plate 1420 is fixedly connected to the second connecting rod 1410. One end of the second connecting rod 1410 has a through hole, through which the extrusion plate 1420 passes to achieve a fixed connection. One end of the second connecting rod 1410 and the extrusion plate 1420 can also be fixedly connected by any of the following methods, such as bolt connection, welding, or adhesive connection.

[0055] The second connecting rod 1410 can rotate under the drive of the fan 1200, thereby causing the extrusion plate 1420 to rotate. The force plate 1430 is used to be squeezed when the extrusion plate 1420 rotates to a second specific position, so as to generate rotation around the first direction, thereby driving the guide plate 1440 to rotate around the first direction. When the extrusion plate 1420 rotates to a third specific position, it is no longer squeezed, so as to generate rotation around the second direction, thereby driving the guide plate 1440 to rotate around the second direction, until the guide plate 1440 returns to its original position. The first direction and the second direction are opposite.

[0056] It should be noted that the axis around which the fan 1200 rotates, the axis around which the second connecting rod 1410 rotates, and the axis around which the extrusion plate 1420 rotates are the same axis. When the extrusion plate 1420 rotates to the second specific position, the force plate 1430 begins to be compressed, resulting in bending deformation. As the extrusion plate 1420 continues to rotate around the first direction, the degree of bending deformation of the force plate 1430 increases. When the extrusion plate 1420 rotates to the third specific position, the force plate 1430 is compressed to a degree of deformation that allows the force plate 1430 to pass directly. After the force plate 1430 passes the third specific position, the extrusion plate 1420 rotates around the second direction, thereby driving the guide plate 1440 to rotate around the second direction until the guide plate 1440 returns to its original position.

[0057] In some disclosed embodiments, the force plate 1430 and the flow guide plate 1440 can be directly fixedly connected.

[0058] In some publicly disclosed embodiments, such as Figure 4 The flow guiding assembly 1400 also includes a torsion spring rod 1450. The torsion spring rod 1450 is rotatably connected to the inner wall of the head-mounted display device body 1000, and the force-bearing plate 1430 is fixedly connected to the torsion spring rod 1450, while the flow guiding plate 1440 is fixedly connected to the torsion spring rod 1450.

[0059] The second connecting rod 1410 can rotate under the drive of the fan 1200, thereby causing the extrusion plate 1420 to rotate. The force plate 1430 is used to be squeezed when the extrusion plate 1420 rotates to the second specific position, so as to generate rotation around the first direction, thereby causing the torsion spring rod 1450 to rotate, so as to drive the guide plate 1440 to rotate around the first direction. When the extrusion plate 1420 rotates to the third specific position, it is no longer squeezed, so as to generate rotation around the second direction. The torsion spring rod 1450 generates rotation in the opposite direction, so as to drive the guide plate 1440 to rotate around the second direction, until the guide plate 1440 returns to its original position.
