Description

Technical Field

[0001] This invention relates to the field of VR glasses technology, specifically to a VR glasses mid-shell positioning detection device and its detection method. Background Technology

[0002] VR headsets use head-mounted display devices to block out a person's vision and hearing from the outside world, guiding the user to feel as if they are in a virtual environment. The display principle is that the left and right eye screens display images for the left and right eyes respectively. After the human eye receives this information with differences, it generates a sense of three-dimensionality in the brain.

[0003] In the VR glasses manufacturing process, it is necessary to perform positioning tests on the mid-shell frame of the VR glasses to check for deformation, so that the corresponding installation positions of various components inside the mid-shell are accurate. However, ordinary positioning devices are uncertain about the positioning position of the mid-shell, resulting in unstable test data when inspecting the quality of the mid-shell. Ultimately, this leads to a large number of defective products during the installation stage. Therefore, we propose a positioning fixture for the mid-shell of VR glasses. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, a positioning detection device and method for the mid-shell of VR glasses are provided to solve the problem of unstable detection data when using ordinary positioning devices to monitor the deformation of the mid-shell frame during the VR glasses production process.

[0005] To achieve the above objectives, a positioning detection device for the mid-shell of VR glasses is provided, comprising: The base has a receiving groove formed on it. Two limiting plates are slidably provided on opposite sides of the bottom of the receiving groove. Anti-friction rollers are installed on opposite sides of the two limiting plates. A first driving mechanism for driving the two limiting plates to move closer or further apart is installed on the base. Positioning plates are slidably provided at opposite ends of the receiving groove. A second driving mechanism for the two positioning plates to move closer or further apart is installed on the base. The two positioning plates and the two limiting plates enclose a clamping space for embedding the middle shell of the VR glasses. A reference base is coaxially arranged with the clamping space. A support plate is mounted on the base. Multiple spokes that can move radially along the reference base are slidably mounted on the reference base. A pressure sensor is installed at the end of each spoke that is away from the axis of the reference base. A linkage extrusion member is vertically mounted on the reference base. The outer diameter of the linkage extrusion member gradually increases from bottom to top. The linkage extrusion member is suspended from the support plate by a height-adjustable drive member. The height of the drive member is adjusted so that the reference base rests on the bottom of the groove and is coaxially arranged inside the middle shell. The height of the drive member is further adjusted so that the lower end of the linkage extrusion member is inserted between the other ends of the multiple spokes and pushes the multiple spokes outward. The multiple spokes extend outward at the same time so that the pressure sensor at one end of the multiple spokes presses against the inner wall of the middle shell. The pressure values ​​collected by the multiple pressure sensors determine whether the middle shell is deformed.

[0006] Furthermore, the bottom of the receiving groove is formed with a sliding groove, and the bottom of the limiting plate is formed with a sliding seat. The sliding seat is slidably disposed in the sliding groove. The first driving mechanism includes a screw, which is rotatably installed in the sliding groove. The screw is arranged in the same direction as the sliding groove. The sliding seat is provided with a threaded hole. The threads at both ends of the screw are in opposite directions. The two ends of the screw are respectively screwed into the threaded holes of the two sliding seats.

[0007] Furthermore, one end of the screw extends to the outside of the base and is connected to a manual control disc.

[0008] Furthermore, guide holes are provided on the opposite sides of the accommodating groove, and a guide rod is connected to the limiting plate, with the guide rod sliding in the guide hole.

[0009] Furthermore, strip-shaped holes are respectively formed at opposite ends of the groove wall along the length direction of the receiving groove, and sliders are respectively formed on opposite sides of the positioning plate, and the sliders are slidably disposed in the strip-shaped holes.

[0010] Furthermore, the second drive mechanism includes: The lead screw has a threaded hole in the slider, and the threads at both ends of the lead screw are in opposite directions. The two ends of the lead screw are respectively screwed into the threaded holes of the sliders on the two positioning plates. An electric motor drives the lead screw.

[0011] Furthermore, the reference base has a vertically oriented axial channel, the linkage extrusion member slides in the axial channel, the circumferential side of the reference base has a sliding channel communicating with the axial channel, the spokes slide in the sliding channel, the top of the reference base has a vertical hole communicating with the upper end of the axial channel, the linkage extrusion member is connected to a transmission rod, the transmission rod slides in the vertical hole, and the end of the transmission rod away from the linkage extrusion member is connected to the driving member.

[0012] Furthermore, the driving component is an electro-hydraulic push rod.

[0013] Furthermore, a roller is rotatably mounted on the other end of the spoke.

[0014] This invention provides a method for mid-shell positioning detection of VR glasses using a mid-shell positioning detection device, comprising the following steps: The middle shell of the VR glasses is placed in the receiving groove of the base, so that the middle shell is positioned between the two limiting plates; The first driving mechanism drives the two limiting plates to move closer to each other and abut against the opposite sides of the middle shell; The second driving mechanism drives the two positioning plates to move closer to each other, and the two positioning plates and the two limiting plates enclose a clamping space so that the middle shell is embedded in the clamping space, so that the middle shell and the reference base are coaxially arranged. The height of the drive component is adjusted so that the reference seat rests on the bottom of the slot and is coaxially disposed within the middle shell. Continue to adjust the height of the drive component so that the lower end of the linkage extrusion component is inserted between the other ends of the multiple spokes and pushes the multiple spokes outward. The multiple spokes extend outward at the same time so that the pressure sensor at one end of the multiple spokes presses against the inner wall of the middle shell. The determination of whether the middle shell is deformed is based on the pressure values ​​collected by the multiple pressure sensors.

[0015] The beneficial effects of this invention are as follows: the VR glasses mid-shell positioning detection device of this invention uses a first driving mechanism to drive two limiting plates to clamp the mid-shell, and then uses a second driving mechanism to drive two positioning plates to position the mid-shell, so that the mid-shell is accurately set in the clamping space. Then, a driving component drives the reference seat downwards, moving it inside the mid-shell. When the reference seat reaches the lowest point of the mid-shell, it is restricted, and the linkage pressing component continues to move downwards, causing the inclined surface of the linkage pressing component to press against each spoke. This causes each spoke and the pressure sensor to move outwards, with the pressure sensor pressing against the inner wall of the mid-shell. The data from each pressure sensor is then used to determine whether the mid-shell has deformed. The VR glasses mid-shell positioning detection device of this invention provides stable detection data for deformation detection of the VR glasses mid-shell, improving the quality of mid-shell quality inspection and effectively increasing the pass rate of VR glasses production.

Detailed Implementation

[0024] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] Reference Figures 1 to 7 As shown, the present invention provides a mid-shell positioning detection device for VR glasses, including: a base 1 and a reference base 2.

[0027] In this embodiment, the middle shell of the VR glasses refers to the middle outer shell or main frame of the VR glasses. It is a key structural part that connects the front shell (including lenses) and the headband assembly. It mainly plays the role of supporting the internal components, maintaining the overall shape, and ensuring wearing comfort.

[0028] A receiving groove is formed on the base 1. In this embodiment, the base 1 includes a base plate and a positioning frame. Specifically, the positioning frame is fixedly provided at the upper end of the base plate. The base plate and the positioning frame constitute a box structure with a bottom but no lid. The receiving groove is formed inside this box structure.

[0029] Two limiting plates 11 are movably disposed within the receiving groove. The two limiting plates 11 are disposed opposite to each other. In this embodiment, the receiving groove is cuboid in shape. The two limiting plates 11 are disposed on opposite sides in the width direction of the receiving groove. Specifically, two limiting plates 11 are slidably disposed on opposite sides of the bottom of the receiving groove. Anti-friction rollers 12 are installed on opposite sides of the two limiting plates 11.

[0030] The positioning frame has symmetrically movable limiting plates on its front and rear sides. Several rollers are evenly embedded in a circular array on the opposite sides of the limiting plates. The rollers do not limit the lateral displacement of the inner shell.

[0031] A first drive mechanism 13 is installed on the base 1 to drive the two limiting plates 11 to move closer or further apart. Positioning plates 14 are slidably mounted on opposite ends of the receiving groove. A second drive mechanism 15 is installed on the base 1 to drive the two positioning plates 14 to move closer or further apart. The two positioning plates 14 and the two limiting plates 11 together form a clamping space a for the middle shell 3 of the VR glasses to be embedded.

[0032] A reference base 2 is coaxially arranged with the clamping space a. A support plate 16 is mounted on the base 1. Multiple spokes 21, which can move radially along the reference base 2, are slidably mounted on the reference base 2. A pressure sensor 22 is installed at the end of the spokes 21 away from the axis of the reference base 2. A linkage extrusion member 23 is vertically mounted on the reference base 2. The outer diameter of the linkage extrusion member 23 gradually increases from bottom to top. The linkage extrusion member 23 is suspended from the support plate 16 by a height-adjustable drive member 24.

[0033] The height of the drive component 24 is adjusted so that the reference base 2 rests on the bottom of the groove and is coaxially arranged inside the middle shell 3. The height of the drive component 24 is further adjusted so that the lower end of the linkage pressing component 23 is inserted between the other ends of the multiple spokes 21 and pushes the multiple spokes 21 outward. The multiple spokes 21 extend outward simultaneously so that the pressure sensor 22 at one end of the multiple spokes 21 presses against the inner wall of the middle shell 3. The pressure values ​​collected by the multiple pressure sensors 22 are used to determine whether the middle shell 3 is deformed.

[0034] A groove is formed at the bottom of the receiving slot. A sliding seat 111 is formed at the bottom of the limiting plate 11. The sliding seat 111 slides in the groove. The first drive mechanism 13 includes a screw. The screw is rotatably mounted in the groove. The screw and the groove are arranged in the same direction. The sliding seat 111 has a threaded hole. The threads at both ends of the screw are in opposite directions. The two ends of the screw are respectively screwed into the threaded holes of the two sliding seats 111.

[0035] In a preferred embodiment, one end of the screw extends to the outside of the base 1 and is connected to a manual disc 131.

[0036] In this embodiment, a sliding seat is fixedly connected to the lower center of each limiting plate. The sliding seat is movably limited and inserted into the groove at the bottom of the receiving groove. The groove is set along the width direction of the receiving groove. The middle part of each sliding seat is threaded to a screw rod. The threads at both ends of the screw rod are in opposite directions. The screw rod is rotatably mounted in the groove via bearings. The front end of the screw rod extends to the outer side of the front end of the base plate. A manual disc is fixedly sleeved on the front end of the screw rod.

[0037] The screw can be manually rotated to make the two limiting plates move relative to or in opposite directions.

[0038] In a preferred embodiment, guide holes are provided on the opposite sides of the receiving groove. A guide rod 112 is connected to the limiting plate 11. The guide rod 112 is slidably disposed in the guide hole.

[0039] In this embodiment, guide rods are fixedly connected to the opposite sides of the two limiting plates. Each limiting plate is provided with two guide rods. The guide rods are movably inserted into the guide holes on the front and rear side walls of the positioning frame. The guide rods enable the limiting plates to maintain stable displacement.

[0040] See Figure 1As shown, each end of the groove wall has a strip-shaped hole b that runs along the length of the groove. Slider blocks 141 are formed on opposite sides of the positioning plate 14. The sliders 141 slide within the strip-shaped holes b.

[0041] In this embodiment, sliders are fixedly connected to both ends of the positioning plates, and the sliders are inserted through the strip holes on the left and right sides of the positioning frame. A fixing seat is fixedly connected to the lower part of the sliders on the same side of both positioning plates. The fixing seat has a threaded hole. The end of the lead screw is screwed into the threaded hole of the fixing seat. The threads at both ends of the lead screw are in opposite directions, so that after the lead screw is electrically driven, the two positioning plates move closer to each other or further apart.

[0042] The second drive mechanism 15 includes a lead screw 152 and a motor 153.

[0043] Specifically, the slider 141 has a threaded hole. The threads at both ends of the lead screw 152 are in opposite directions. The two ends of the lead screw 152 are respectively screwed into the threaded holes of the slider 141 on the two positioning plates 14.

[0044] Motor 153 is driven by lead screw 152. In this embodiment, the output shaft of the motor is coaxially connected to one end of the lead screw.

[0045] The reference base 2 has a vertically oriented axial channel c. The linkage extrusion member 23 slides within the axial channel c. A sliding channel communicating with the axial channel c is formed on the circumferential side of the reference base 2. The spoke 21 slides within the sliding channel, and a vertical hole communicating with the upper end of the axial channel c is formed on the top of the reference base 2. A transmission rod 231 is connected to the linkage extrusion member 23. The transmission rod 231 slides within the vertical hole. The end of the transmission rod 231 furthest from the linkage extrusion member 23 is connected to the drive member 24.

[0046] In a preferred embodiment, a roller 211 is rotatably mounted on the other end of the spoke 21.

[0047] In this embodiment, a support plate is fixedly connected to the rear side of the base plate via a support plate. The support plate is positioned above the positioning frame. A driving component is fixedly connected to the middle of the support plate. The driving component is an electric telescopic rod or an electro-hydraulic push rod. The driving component is connected to a transmission rod. The lower end of the transmission rod is fixedly connected to a linkage extrusion component. The linkage extrusion component is shaped like an inverted frustum. In this embodiment, the linkage extrusion component, the transmission rod, and the driving component are coaxially arranged. The linkage extrusion component can be slidably mounted inside the axial channel of the reference base.

[0048] The reference base is rectangular in shape. Sliding channels are formed on the four circumferential sides of the reference base (i.e., front, rear, left, and right). The sliding channels on the front and rear sides of the reference base are arranged along the width direction of the reference base. The sliding channels on the left and right sides of the reference base are arranged along the length direction of the reference base. A pressure sensor is fixedly connected to the far end of the spoke (i.e., the end of the spoke furthest from the central channel), while a roller is rotatably connected to the near end of the spoke. When the linkage extrusion component is inserted between the four spokes, because the linkage extrusion component is truncated cone-shaped, its circumferential sides are inclined. The rollers of the four spokes press against the inclined surface of the linkage extrusion component. When the linkage extrusion component slides downwards, the spokes are pushed out of the sliding channels; conversely, when the linkage extrusion component slides upwards, the spokes are pushed into the sliding channels under the elastic force of the elastic element.

[0049] As a preferred embodiment, the drive component 24 is an electro-hydraulic push rod.

[0050] A limiting rod is fixedly connected to the upper part of the reference base. A vertical through hole is provided on the support plate. The limiting rod slides in the vertical view. The limiting rod makes the vertical displacement of the reference base more stable, so that the reference base can be accurately set in the middle shell, and an equidistant gap is formed between the inner wall of the middle shell (undeformed middle shell) and the circumferential side of the reference base.

[0051] In this embodiment, the wall of the sliding channel is formed with an assembly groove. The assembly groove is provided along the length direction of the sliding channel. An ear plate is formed on the outside of the spoke. The ear plate slides in the assembly groove. An elastic element, which is a spring, connects the ear plate and the assembly groove. When the linkage extrusion member slides upward, the spring pulls the pressure sensor on the spoke back into the sliding channel.

[0052] When the spring is compressed, the outer end of the spoke will be retracted into the sliding channel of the reference seat when no force is applied.

[0053] The positioning plate can be replaced, and by replacing the positioning plate with one made of different materials, the clamping and positioning of the shell in different materials can be satisfied.

[0054] This invention provides a method for mid-shell positioning detection of VR glasses using a mid-shell positioning detection device, comprising the following steps: S1. Place the middle shell 3 of the VR glasses into the receiving groove of the base 1, so that the middle shell 3 is positioned between the two limiting plates 11.

[0055] S2. The first driving mechanism 13 drives the two limiting plates 11 to move closer to each other and abut against the opposite sides of the middle shell 3.

[0056] S3. The two positioning plates 14 are driven to move closer to each other by the second driving mechanism 15. The two positioning plates 14 and the two limiting plates 11 enclose and form a clamping space a so that the middle shell 3 is embedded in the clamping space a, so that the middle shell 3 and the reference seat 2 are coaxially arranged.

[0057] S4. Adjust the height of the drive component 24 so that the reference seat 2 rests on the bottom of the slot and is coaxially set inside the middle shell 3.

[0058] S5. Continue to adjust the height of the drive component 24 so that the lower end of the linkage extrusion component 23 is inserted between the other ends of the multiple spokes 21 and pushes the multiple spokes 21 outward. The multiple spokes 21 extend outward at the same time so that the pressure sensor 22 at one end of the multiple spokes 21 presses against the inner wall of the middle shell 3.

[0059] S6. Determine whether the shell 3 is deformed based on the pressure values ​​collected by multiple pressure sensors 22.

[0060] When using the VR glasses mid-shell positioning detection device of the present invention, the mid-shell is first placed between two limiting plates, and then the manual disk is manually rotated. By rotating the screw, the two sliding seats are displaced relative to each other, and the two limiting plates are displaced relative to each other, so that the outer side of the roller contacts the side wall of the mid-shell.

[0061] Then, the motors of the second drive mechanism on the front and rear sides are started. The motors drive the lead screw in the middle of the corresponding lead screw to rotate, thereby driving the two positioning plates to move closer to each other and positioning and pressing the left and right ends of the middle shell, so that the middle shell is centered inside the positioning groove.

[0062] Finally, the drive unit (electric telescopic rod) is activated, causing the reference seat to move downwards and into the middle shell. When the reference seat reaches the bottom of the middle shell (as shown in the figure), the lower end of the reference seat is restricted, and the linkage extrusion unit continues to move downwards. This causes the inclined surface of the linkage extrusion unit to press against each roller, which in turn causes each spoke and pressure sensor to move outwards, thus pressing against the inner wall of the middle shell. The data from each pressure sensor is used to determine whether the middle shell is deformed. If the values ​​of each pressure sensor are the same, the middle shell is not deformed; otherwise, the middle shell is deformed.

[0063] The VR glasses mid-shell positioning detection device of this invention uses a first driving mechanism to drive two limiting plates to clamp the mid-shell, and a second driving mechanism to drive two positioning plates to position the mid-shell, ensuring the mid-shell is accurately positioned in the clamping space. A driving component then moves a reference seat downwards, placing it inside the mid-shell. When the reference seat reaches the bottom of the mid-shell, it is restricted, and the linkage pressing component continues to move downwards, causing its inclined surface to press against each spoke. This causes the spokes and pressure sensors to move outwards, pressing against the inner wall of the mid-shell. Data from these pressure sensors is then used to determine if the mid-shell is deformed. This VR glasses mid-shell positioning detection device provides stable data for mid-shell deformation detection, improving the quality of mid-shell quality inspection and effectively increasing the VR glasses production pass rate.

[0064] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
