All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
Please refer to fig. 1 and fig. 2, which are a schematic diagram and an exploded view of a pair of virtual reality glasses according to an embodiment of the present application. As shown in the figure, the virtual reality glasses 1 include a lens barrel assembly 10, a support frame assembly 11, and a display screen 12. The support frame assembly 11 is disposed on the lens barrel assembly 10, and the display screen 12 is disposed on a side of the support frame assembly 11 away from the lens barrel assembly 10.
Please refer to fig. 3 and 4, which are an exploded view of a lens barrel assembly and a lower view of a lens barrel body according to an embodiment of the present application. As shown, the barrel assembly 10 includes a barrel body 100 and a first lens 101. The lens barrel body 100 has a first light-passing hole 1000, a first end surface 1001 and a second end surface 1002 opposite to each other. The first end surface 1001 and the second end surface 1002 surround the first light-transmitting aperture 1000. Wherein the inner surface of the lens barrel body 100 is provided with a first step portion 1003, and the first step portion 1003 surrounds the first light transmission hole 1000. Specifically, the first step 1003 is formed by recessing an inner edge of the first end surface 1001 near the first light transmission hole 1000. Further, the first step 1003 corresponds in size and shape to the first lens 101 so that the first lens 101 can be disposed on the first step 1003.
In some embodiments, the first step 1003 may be connected to the first lens 101 by a first adhesive. For example, the first adhesive may include Latex (Latex), acrylic resin (Acrylic resin), epoxy resin (Phenolic epoxy resin), polyurethane (PU), or any combination thereof, but is not limited thereto. The first lens 101 and the first step 1003 are fixed by the first adhesive, so that the structure of the lens barrel assembly 10 can be more stable.
In some embodiments, the lens barrel body 100 may have a connection boss 1004. The connection protrusion 1004 is provided on the second end face 1002 and extends in a direction away from the second end face 1002. Specifically, the connection protrusion 1004 is formed by protruding an outer edge of the second end surface 1002 away from the first light-transmitting hole 1000. The coupling protrusion 1004 is for coupling with the support bracket body 110 (which will be explained in detail later).
In some embodiments, the first lens 101 may be a flat lens. That is, the first lens 101 may have no curvature. In addition, the first lens 101 may have a multilayer film structure. For example, the first lens 101 may include various functional layers such as a hydrophobic layer, a filter layer, an anti-abrasion layer, etc. to further enhance the performance of the first lens 101. It should be noted that the above examples are only examples. In other embodiments, the first lens 101 may be a convex lens or a concave lens, depending on the overall design.
Please refer to fig. 5 and 6, which are an exploded view of a support frame assembly and a lower view of a support frame body according to an embodiment of the present application. The support frame assembly 11 is disposed on the lens barrel assembly 10. More specifically, the support frame assembly 11 is disposed on the second end face 1002 of the barrel assembly 10. The support frame assembly 11 includes a support frame body 110, a second lens 111, and a third lens 112.
The support frame body 110 has a second light through hole 1100, a third end surface 1101 and a fourth end surface 1102 opposite to each other. The third end surface 1101 and the fourth end surface 1102 surround the second light-passing hole 1100. The inner surface of the support frame body 110 is provided with a second step portion 1103 and a third step portion 1104, and the second step portion 1103 and the third step portion 1104 encircle the second light-passing hole 1100. Specifically, the second stepped portion 1103 is formed by the inner edge of the third end surface 1101 near the second light passing hole 1100 being recessed downward; the third step 1104 is formed by the second step 1103 being recessed downward near the inner edge of the second light-passing hole 1100. That is, the supporting frame body 110 has a stepped structure therein. Further, the second stepped portion 1103 has a size and shape corresponding to the second lens 111 such that the second lens 111 is disposed on the second stepped portion 1103; the third step 1104 has a size and shape corresponding to the third lens 112 such that the third lens 112 is disposed on the third step 1104.
In this embodiment, the third end 1101 of the support frame body 110 is connected to the second end 1002. To make the connection more secure, in some embodiments, the outer surface of the support bracket body 110 may be provided with a fourth step 1105. Specifically, the fourth step portion 1105 is formed by recessing the outer edge of the third end surface 1101 away from the second light through hole 1100. Therefore, the fourth step portion 1105 is connected to the connection boss 1004, so that the holder body 110 and the barrel body 100 can be engaged with each other.
In some embodiments, the fourth step 1105 may be connected to the connection boss 1004 by a fourth adhesive. The fourth adhesive may be similar to or the same as the first adhesive, and thus will not be described in detail.
In some embodiments, the support frame body 110 may further include an air escape groove 1106, wherein the air escape groove 1106 is concavely formed on the inner surface of the support frame body 110. When the support frame assembly 11 is assembled, the gas expanding or contracting due to the temperature change can enter or exit the support frame assembly 11 through the gas escape groove 1106, so as to avoid the excessive or insufficient pressure of the gas inside the support frame assembly 11. In this way, the support frame assembly 11 can prevent the lens from being deviated or damaged due to the expansion or contraction of the gas, thereby affecting the display effect.
The second lens 111 is disposed on the second stepped portion 1103. In some embodiments, the second lens 111 has a first radius of curvature. The second lens 111 may be a concave lens, for example. That is, the first radius of curvature of both surfaces of the second lens 111 is a negative value; alternatively, the first radius of curvature of one of the two surfaces is a negative value of a larger value and the first radius of curvature of the other of the two surfaces is a positive value of a smaller value. Further, when the second lens 111 is a concave lens, the second stepped portion 1103 may be provided corresponding to the second lens 111 and have a corresponding curved shape. In addition, the second lens 111 may be a multilayer film structure. For example, the second lens 111 may include various functional layers such as a hydrophobic layer, a filter layer, an anti-abrasion layer, etc. to further enhance the performance of the second lens 111. It should be noted that the above examples are only examples. In other embodiments, the second lens 111 may be a flat lens or a convex lens, depending on the overall design.
In some embodiments, the second step 1103 may be connected to the second lens 111 by a second adhesive. The second adhesive may be similar to or the same as the first adhesive, and thus will not be described in detail.
The third lens 112 is disposed on the third step 1104. In some embodiments, the third lens 112 has a second radius of curvature. For example, the third lens 112 may be a convex lens. That is, the second radii of curvature of both surfaces of the third lens 112 are positive values; alternatively, the second radius of curvature of one of the two surfaces is a more positive value and the second radius of curvature of the other of the two surfaces is a less negative value. Further, when the third lens 112 is a convex lens, the third stepped portion 1104 may be provided corresponding to the third lens 112 and have a corresponding curved shape. In addition, the third lens 112 may be a multi-layered film structure. For example, the third lens 112 may include various functional layers such as a hydrophobic layer, a filter layer, an anti-abrasion layer, etc. to further enhance the performance of the third lens 112. It should be noted that the above examples are only examples. In other embodiments, the third lens 112 may be a flat lens or a concave lens, depending on the overall design.
In some embodiments, the third step 1104 may be connected to the third lens 112 by a third adhesive. The third adhesive may be similar to or the same as the first adhesive, and thus will not be described in detail.
The display 12 is disposed on the fourth end surface 1102. For example, the display screen 12 may include a substrate, a driving layer, a liquid crystal display layer, a filter layer, a light guide layer, and the like, but is not limited thereto. In some embodiments, the display screen 12 may also be other types of displays and be used to provide display functionality. In some embodiments, the display 12 may be secured to the fourth end surface 1102 of the support frame assembly 11 by locking, adhering, clamping, etc. as will be appreciated by those skilled in the art.
In view of the foregoing, the present application provides a virtual reality glasses architecture suitable for automatic assembly. Therefore, hereinafter, the assembling method of the virtual reality glasses is further described to make the technical features of the present application more apparent.
Please refer to fig. 7, which illustrates a method for assembling virtual reality glasses according to an embodiment of the present application. It should be noted that the sequence of steps hereinafter is not necessarily constant and some steps may be performed simultaneously, omitted or added. The flow chart is presented in a broad and simplified manner to describe the steps of the present application and is not intended to limit the order or number of steps of the method of manufacturing of the present application. As shown in the figure, the method for assembling the virtual reality glasses includes:
step S10: a barrel body 100 and a first lens 101 are provided. The lens barrel body 100 has a first light-passing hole 1000, and a first end surface 1001 and a second end surface 1002 opposite to each other, the first end surface 1001 and the second end surface 1002 surrounding the first light-passing hole 1000, wherein the inner surface of the lens barrel body 100 is provided with a first step portion 1003, the first step portion 1003 surrounding the first light-passing hole 1000.
Step S11: the first lens 101 is aligned with the barrel body 100.
Fig. 8 to 10 are schematic diagrams of the first sub-step of the method for assembling the virtual reality glasses, the lens barrel body, and the first lens according to an embodiment of the disclosure. As shown, in some embodiments, the step of aligning the first lens 101 with the barrel body 100 may further include:
sub-step S110: four corners of the first step 1003 are set as the first position A1.
Substep S111: the geometric centers of the four first positions A1 are set as first center points C1.
Substep S112: four corners of the first lens 101 are set to the second position A2.
Substep S113: the geometric centers of the four second positions A2 are set as second center points C2.
Substep S114: the lateral movement and rotation of the barrel body 100 and the first lens 101 are calibrated by the first center point C1 and the second center point C2.
Substep S115: the tilt of the lens barrel body 100 and the first lens 101 is calibrated by the four first positions A1 and the four second positions A2.
For example, the automated assembly machine may obtain the above parameters through components such as an imaging device, an image processing device, and a processor, and perform self-alignment by calculation to realize a high-precision and automated assembly process. Therefore, the problems of poor precision, high number and high damage rate caused by manual assembly in the prior art can be solved.
Step S12: the first lens 101 is disposed on the first step 1003 of the barrel body 100 to form the barrel assembly 10. The first lens 101 may be adhered to the first step portion 1003 by a first adhesive, and cured by baking, drying, or air drying.
Step S13: a support frame body 110, a second lens 111 and a third lens 112 are provided. The support body 110 has a second light-passing hole 1100 and a third end surface 1101 and a fourth end surface 1102 opposite to each other, the third end surface 1101 and the fourth end surface 1102 encircle the second light-passing hole 1100, wherein the inner surface of the support body 110 is provided with a second step portion 1103 and a third step portion 1104, the second step portion 1103 and the third step portion 1104 encircle the second light-passing hole 1100, and the third end surface 1101 is connected with the second end surface 1002.
Step S14: the second lens 111, the third lens 112 and the support frame body 110 are aligned.
Please refer to fig. 11 and 13, which are a second sub-step of the method for assembling the virtual reality glasses, a schematic diagram of the support frame body, and a schematic diagram of the second lens according to an embodiment of the disclosure. As shown, in some embodiments, the second step 1103 has two straight sides and two arcuate sides. The second lens 111 has two straight sides and two curved sides. Therefore, the step of aligning the second lens 111, the third lens 112 and the support frame body 110 may further include:
substep S140A: the lateral movement of the support frame body 110 and the second lens 111 is calibrated by the two straight sides and the two arc sides of the second stepped portion 1103 and the two straight sides and the two arc sides of the second lens 111.
Sub-step S141A: the rotation of the support frame body 110 and the second lens 111 is calibrated by the two straight sides of the second stepped portion 1103 and the two straight sides of the second lens 111.
Sub-step S142A: four corners of the second step portion 1103 are set to the third position A3.
Sub-step S143A: the geometric centers of the four third positions A3 are set as third center points C3.
Sub-step S144A: four corners of the second lens 111 are set to the fourth position A4.
Sub-step S145A: the geometric center of the four fourth positions A4 is set as a fourth center point C4.
Substep S146A: the tilt of the support frame body 110 and the second lens 111 is calibrated by the four fourth positions A4 and the four third positions A3.
In some embodiments, an unclear condition may occur in image processing due to the smaller horizontal area of the second stepped portion 1103. Therefore, when it is difficult for the automatic assembly apparatus to distinguish the straight side edge of the second stepped portion 1103, the L-shaped protrusions 1107 at the four corners of the support frame body 110 may be used instead as positioning points to perform the lateral movement and rotation of the support frame body 110 and the second lens 111.
Fig. 14 to 16 are respectively a third sub-step of the method for assembling the virtual reality glasses, another schematic view of the support frame body, and a schematic view of the third lens according to an embodiment of the disclosure. As shown, in some embodiments, the third step 1104 has four straight sides L1. Specifically, the side L1 is the inner side of the third step 1104, that is, the side surrounding the inner ring of the second light-transmitting hole 1100. The third lens 112 has four virtual line segments L2. Specifically, the virtual line segment L2 referred to above corresponds to the inner side edge of the third step 1104. Therefore, the step of aligning the second lens 111, the third lens 112 and the support frame body 110 may further include:
substep S140B: the support frame body 110 and the lateral movement of the third lens 112 are aligned by the four straight sides L1 of the third step 1104 and the four virtual line segments L2 of the third lens 112.

The four straight sides L1 may be two opposite straight sides L1 or two adjacent straight sides L1. Likewise, the four virtual line segments L2 may be two virtual line segments L2 opposing each other or two virtual line segments L2 adjacent to each other.
Sub-step S142B: four corners of the third step 1104 are set to the fifth position A5.
