Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and in particular to a thrust testing fixture for eyeglasses products. Background Technology

[0002] Virtual reality (VR) glasses are products that integrate simulation technology with computer graphics, human-computer interface technology, multimedia technology, sensing technology, and network technology. They represent a novel means of human-computer interaction created using computers and the latest sensor technologies. VR glasses are a revolutionary product. They not only allow enthusiasts to experience wonder and excitement, but also fascinate them with the unknown aspects of their origin and future. They offer a vast library of VR videos, cool VR games, and stunning panoramic videos, enabling users to experience a truly immersive virtual world.

[0003] Therefore, virtual reality glasses have a very good market prospect and application value in current life, and they have been favored by a large number of consumers. Basically, everyone knows their uses and the fun of using them.

[0004] For existing virtual reality glasses, refer to the accompanying drawings in this application specification. Figure 1 As shown, the frame 2000 has an opening groove 10, and a small light-transmitting sheet 1000 is hot-pressed and fixed in the opening groove 10. Since the small light-transmitting sheet 1000 is small and inconspicuous, and the frame 2000 is an elliptical structure with a certain curvature, in the prior art, the small light-transmitting sheet 1000 is generally not subjected to a thrust test. That is to say, after hot-pressing and fixing, no thrust test is performed on its adhesive strength, so it is impossible to know its hot-pressing firmness. Subsequently, after the product is manufactured and sold, many customers reported that it would fall off after a period of use and need to be returned to the factory for repair. The main reason for the fall-off is obviously that the hot-pressing is not firm.

[0005] Therefore, it is necessary to design a fixture for testing the thrust of the corresponding small light-transmitting sheet after hot pressing and fixing.

[0006] In response, the inventor of this patent, based on the actual situation, deeply considered the relevant problems encountered in the work, reviewed a large amount of scientific research data and literature, and conducted a novelty search through the website of the State Intellectual Property Office, and gradually conceived and designed this application to solve the relevant technical problems.

[0023] According to one embodiment of the present invention, each of the elastic pressure-relieving members includes a pressure-fixing post and a pressure-relieving spring connected upward to the top of the pressure-fixing post;

[0024] The bottom surface of the product pressure plate has multiple guide grooves that correspond to multiple pressing positions of the mirror frame; the upper ends of multiple pressure-relieving springs are fixed to the top of the multiple guide grooves; the upper parts of multiple pressure-fixing columns are correspondingly limited within the multiple guide grooves.

[0033] In its specific implementation, this application can be used to fix the frame of a virtual reality glasses with a small light-transmitting film hot-pressed into a pre-set opening groove on the inner surface. A thrust test is then performed on the corresponding hot-pressed small light-transmitting film. After hot-pressing, a preset force can be applied to evaluate the firmness of the hot-pressing fixation. Products that pass the thrust test can then proceed to subsequent processes and be finally manufactured into products for sale, thereby greatly reducing the number and probability of products being returned to the factory for repair due to detachment.

[0034] Furthermore, by setting the pressure sensor, this application can effectively detect the thrust value exerted by the pushing member on the small light-transmitting sheet that is hot-pressed and fixed in the opening groove. This allows the thrust value to be flexibly adjusted according to actual needs when the application is used to perform thrust tests on the corresponding hot-pressed and fixed small light-transmitting sheet.

[0035] Meanwhile, the counterforce on the pressure sensor described in this application increases gradually, rather than instantaneously, resulting in better protection and making it less prone to sudden damage, thus extending its service life.

[0093] The thrust testing fixture 3000 for eyeglasses products according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0094] Reference Figures 1 to 10As shown, the thrust testing fixture 3000 for eyeglasses products provided according to an embodiment of the present invention is used to fix the frame 2000 of virtual reality glasses with a small light-transmitting film 1000 hot-pressed and fixed in the inner surface of the preset opening groove 10, and to perform thrust testing on the corresponding hot-pressed and fixed small light-transmitting film 1000. It includes a product fixing seat 20, a product pressure plate 30 and a thrust testing component 40.

[0095] The product fixing base 20 has an upwardly protruding product fixing platform 201 in the middle of its upper end surface, and the mirror frame 2000 is fitted outside the product fixing platform 201.

[0096] Furthermore, the product pressure plate 30 is detachably fixed on the product fixing platform 201 to press down and fix the mirror frame 2000; the thrust testing component 40 is movably fixed on the product fixing base 20, with its front end facing the opening slot 10.

[0097] When the thrust test component 40 moves forward by a preset stroke, its front end can move forward into the opening groove 10 and push the small light-transmitting sheet 1000, which is hot-pressed and fixed in the opening groove 10, with a preset force to perform a thrust test on it.

[0098] Based on the above, it is clear that in specific implementation, this application is mainly used as a thrust testing fixture 3000 for eyeglass products.

[0099] Specifically, when applying this application, the accompanying drawings of this application specification should be included in advance. Figure 1 The frame 2000 of the virtual reality glasses, in which a small light-transmitting sheet 1000 is heat-pressed and fixed within the pre-set opening groove 10 on the inner surface, is mounted outside the product fixing platform 201. Then, the product pressure plate 30 is fixed onto the product fixing platform 201 to press and fix the frame 2000 downwards. In this way, the frame 2000 is pressed and fixed in accordance with this application. Subsequently, the pushing member 405 can be used to apply a preset force to push the small light-transmitting sheet 1000, which is heat-pressed and fixed within the opening groove 10, for a certain period of time. For details, please refer to the accompanying drawings of this application specification. Figure 10 As shown, if the small light-transmitting sheet 1000, which is hot-pressed and fixed in the opening groove 10, does not fall off after being pushed by the corresponding preset force for a certain period of time, it indicates that the hot-pressing and fixing between it and the opening groove 10 is qualified. Conversely, if the small light-transmitting sheet 1000, which is hot-pressed and fixed in the opening groove 10, falls off after being pushed by the corresponding preset force for a certain period of time, it indicates that the hot-pressing and fixing between it and the opening groove 10 is unqualified. At this time, the relevant unqualified products can be sorted out for re-hot-pressing and fixing using a suitable hot-pressing fixture.

[0100] As described above, it is clear that in specific implementation, this application can be used to fix the frame 2000 of virtual reality glasses, in which a small light-transmitting sheet 1000 is hot-pressed and fixed within a pre-set opening groove 10 on the inner surface, and to perform a thrust test on the corresponding hot-pressed and fixed small light-transmitting sheet 1000. After hot-pressing and fixing, a preset force can be applied to it through the thrust test to evaluate the firmness of its hot-pressing and fixing. In this way, products that pass the above thrust test can proceed to the subsequent processes and finally be manufactured into products for sale, which can greatly reduce the number and probability of products being returned to the factory for repair due to detachment in the future.

[0101] Furthermore, through the above-mentioned optimized design, this application is highly practical and can provide higher quality assurance and performance guarantee for the product during the entire manufacturing process of virtual reality glasses, making the application effective and easy to promote and popularize.

[0102] Furthermore, in specific implementation, in accordance with... Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, according to an embodiment of the present invention, the thrust testing component 40 includes a forward and backward moving component 401, a bearing plate 402, a sensor fixing seat 403, a pressure sensor 404, and a pushing component 405;

[0103] The support plate 402 is horizontally fixed on the front-rear moving member 401, so as to drive it to move back and forth synchronously through the front-rear moving member 401; the sensor fixing seat 403 is fixed on the rear part of the upper end face of the support plate 402; the pressure sensor 404 is fixed on the sensor fixing seat 403; the pushing member 405 is slidably fixed on the front side of the upper end face of the support plate 402, with its front end facing the opening slot 10 and its rear end facing the pressure sensor 404.

[0104] As described above, it can be understood that when the forward and backward moving component 401 drives the bearing plate 402, the sensor fixing seat 403 and the pressure sensor 404 on it to move forward synchronously by a preset stroke, the front end of the pushing component 405 will push the small light-transmitting sheet 1000 that is hot-pressed and fixed in the opening slot 10, and the rear end will press against the pressure sensor 404, so as to realize the thrust test of the corresponding hot-pressed and fixed small light-transmitting sheet 1000 by the thrust test component 40 described in this application.

[0105] Therefore, by setting the pressure sensor 404, the thrust value of the push member 405 applied to the small light-transmitting sheet 1000 that is hot-pressed and fixed in the opening groove 10 can be accurately detected. This allows the thrust value to be flexibly adjusted according to actual needs when the application is used to perform thrust tests on the corresponding hot-pressed and fixed small light-transmitting sheet 1000.

[0106] Therefore, through the above-mentioned optimized design, the overall performance of this application can be effectively improved.

[0107] Furthermore, in specific implementation, we will continue to refer to... Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, according to one embodiment of the present invention, the jacking member 405 includes front and rear slide rails 4051, front and rear sliders 4052, jacking seat 4053 and jacking head 4054;

[0108] The front and rear slide rails 4051 are fixedly mounted on the front side of the upper end of the support plate 402; the front and rear sliders 4052 are fixedly mounted on the front and rear slide rails 4051 and can slide back and forth; the push seat 4053 is mounted on the front and rear sliders 4052, and the rear end of the push seat 4053 faces the pressure sensor 404; the push head 4054 is mounted on the upper front part of the push seat 4053 and faces the opening slot 10.

[0109] As described above, it can be understood that when the forward and backward moving component 401 drives the bearing plate 402, the sensor fixing seat 403 and the pressure sensor 404 on it to move forward synchronously by a preset stroke, the push head 4054 will push the small light-transmitting sheet 1000 that is hot-pressed and fixed in the opening slot 10, and the rear end of the push seat 4053 will press against the pressure sensor 404, so as to realize the thrust test of the corresponding hot-pressed and fixed small light-transmitting sheet 1000 using the thrust test component 40 of this application.

[0110] Regarding the above, it is clear that when the pushing component 405 includes the front and rear slide rails 4051, the front and rear sliders 4052, the pushing seat 4053, and the pushing head 4054, it indicates that the pushing head 4054 of the pushing component 405 in this application can initially slide back and forth along the front and rear slide rails 4051 following the front and rear sliders 4052. When using this application, the front and rear moving component 401 drives the bearing plate 402, the sensor fixing seat 403, and the pressure sensor 404 on it to move forward synchronously by a preset stroke A. At this time, the pushing head 4054 can just contact the small light-transmitting sheet 1000 that is hot-pressed and fixed in the opening groove 10, and the rear end of the pushing seat 4053 just contacts the pressure sensor 404.

[0111] Subsequently, the forward and backward moving component 401 drives the bearing plate 402, the sensor fixing seat 403 and the pressure sensor 404 on it to move forward synchronously by a preset stroke B. The push head 4054 will then forcefully push the small light-transmitting sheet 1000 that is hot-pressed and fixed in the opening slot 10. The rear end of the push seat 4053 will then press against the pressure sensor 404. In this way, the push force testing component 40 described in this application is used to perform a push force test on the corresponding hot-pressed and fixed small light-transmitting sheet 1000. The corresponding preset stroke A and preset stroke B are the total preset stroke.

[0112] During the above operation, since the forward and backward moving component 401 first drives the bearing plate 402, the sensor fixing seat 403 and the pressure sensor 404 on it to move forward synchronously by a preset stroke A, the push head 4054 just contacts the small light-transmitting sheet 1000 that is hot-pressed and fixed in the opening groove 10, and the rear end of the push seat 4053 just contacts the pressure sensor 404, the pressure sensor 404 of this application is not subjected to a large counter-force in an instant, so that it is well protected and not easily damaged, thus making its service life long.

[0113] Preferably, in this technical solution, the reference is still made. Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, according to one embodiment of the present invention, the jacking member 405 further includes a jacking spring 4055 and a jacking rod 4056;

[0114] The push base 4053 has a front-facing insertion hole 40531 at its rear end; the push spring 4055 is telescopically fitted into the insertion hole 40531 in the front-back direction; the front end of the push rod 4056 extends into the insertion hole 40531 and is fixedly connected to the rear end of the push spring 4055, and the rear end of the push rod 4056 faces the pressure sensor 404.

[0115] As described above, it can be understood that when the forward and backward moving component 401 drives the bearing plate 402, the sensor fixing seat 403 and the pressure sensor 404 on it to move forward synchronously for the corresponding total preset stroke, the push head 4054 will push the small light-transmitting sheet 1000 that is hot-pressed and fixed in the opening slot 10, and the rear end of the push rod 4056 will elastically press against the pressure sensor 404 under the elastic force of the push spring 4055.

[0116] Therefore, when the pusher component 405 of this application also includes the pusher spring 4055 and the pusher rod 4056, it is possible that during the above operation, the bearing plate 402, the sensor fixing seat 403 and the pressure sensor 404 on it can be driven to move forward synchronously by a preset stroke A through the front and rear moving component 401. At this time, the pusher head 4054 just contacts the small light-transmitting sheet 1000 that is hot-pressed and fixed in the opening groove 10, and the rear end of the pusher seat 4053 just contacts the pressure sensor 404.

[0117] Subsequently, the forward and backward moving component 401 drives the bearing plate 402, the sensor fixing seat 403 and the pressure sensor 404 on it to move forward synchronously by a preset stroke B. The push head 4054 will then forcefully push the small light-transmitting sheet 1000 that is hot-pressed and fixed in the opening slot 10. The rear end of the push rod 4056 will elastically press against the pressure sensor 404 under the elastic force of the push spring 4055. In this process, the push spring 4055 can play a role in buffering the counter-thrust force. In this way, the push force testing component 40 described in this application can be used to more reliably test the corresponding hot-pressed and fixed small light-transmitting sheet 1000. Similarly, the corresponding preset stroke A and preset stroke B are the total preset stroke.

[0118] During the process in which the aforementioned forward and backward moving component 401 drives the bearing plate 402, the sensor fixing seat 403 and the pressure sensor 404 on it to move forward synchronously by a preset stroke B, the counter-thrust force on the pressure sensor 404 of this application increases gradually rather than instantaneously, thus providing better protection and making it less likely to be damaged at once, resulting in a longer service life.

[0119] Furthermore, through the above-mentioned optimized design, the overall performance of this application can be further improved.

[0120] Preferably, in this technical solution, according to an embodiment of the present invention, the forward and backward moving component 401 is a screw-driven linear module or a cylinder-driven linear module, which are common in the prior art and are mature product components, so its details are not described in detail here.

[0121] As described above, it is clear that when the forward and backward moving component 401 of this application is a cylinder-driven linear module or a screw-driven linear module, it can automatically move forward a preset stroke to perform a thrust test on the small light-transmitting sheet 1000, and can automatically move backward a preset stroke to facilitate the removal of the frame 2000 of the virtual reality glasses, in which the small light-transmitting sheet 1000 is hot-pressed and fixed in the preset opening groove 10 on the inner surface, from the product fixing table 201.

[0122] Furthermore, in specific implementation, in accordance with Figure 3 , Figure 5 , Figure 8 and Figure 9 As shown, according to an embodiment of the present invention, the product pressure plate 30 is provided with a plurality of elastic pressure-relieving members 301 facing downward on its bottom surface, which correspond to a plurality of pressure-fixing positions of the mirror frame 2000.

[0123] Therefore, when the product pressure plate 30 presses down on the mirror frame 2000, the multiple elastic pressure buffers 301 buffer the downward pressure, making it less likely for the multiple pressure-fixing positions of the mirror frame 2000 to be crushed or cracked, thus making the application highly reliable.

[0124] Preferably, in this technical solution, according to an embodiment of the present invention, each of the elastic pressure-relieving members 301 includes a pressure-fixing post 3011 and a pressure-relieving spring 3012 connected upward to the top of the pressure-fixing post 3011;

[0125] The product pressure plate 30 has multiple guide grooves 302 on its lower bottom surface that correspond to multiple pressing positions of the mirror frame 2000; the upper ends of multiple pressure-relieving springs 3012 are fixedly mounted on the top of the multiple guide grooves 302; and the upper parts of multiple pressure-fixing columns 3011 are correspondingly limited within the multiple guide grooves 302.

[0126] In conclusion, based on the above:

[0127] On the one hand, when each of the elastic pressure-relieving components 301 includes a pressure-fixing post 3011 and a pressure-relieving spring 3012 connected upward to the top of the pressure-fixing post 3011, the pressure is relieved in the vertical direction by multiple pressure-relieving springs 3012, so that the multiple pressure-fixing posts 3011 are not likely to crush or crack the multiple pressure-fixing positions of the frame 2000 in the vertical direction.

[0128] On the other hand, since the upper ends of the multiple pressure-relieving springs 3012 are fixedly mounted on the tops of the multiple guide grooves 302, and in the initial state, the upper parts of the multiple pressure-fixing columns 3011 are correspondingly limited within the multiple guide grooves 302 by interference fit, the multiple guide grooves 302 not only serve to limit and fix the multiple pressure-relieving springs 3012 so that the multiple pressure-relieving springs 3012 can only extend and retract in the vertical direction, but also guide the multiple pressure-fixing columns 3011 in the vertical direction so that they are not easily displaced circumferentially.

[0129] Furthermore, through the above-mentioned optimized design, all of the elastic pressure-relieving components 301 described in this application are stable and reliable in use.

[0130] Furthermore, in specific implementation, we will continue to refer to... Figure 3 , Figure 5 , Figure 8 and Figure 9 As shown, according to an embodiment of the present invention, the upper end face of the product pressure plate 30 is provided with movable grooves 303 on the left and right sides respectively, and movable plates 304 that can slide left and right and telescopic springs 305 fixed inward on the inner side of the movable plates 304 are respectively installed in the two movable grooves 303.

[0131] The two movable plates 304 are respectively provided with handles 306 at the top and L-shaped buckles 307 are respectively fixed to the outside of the bottom of the two movable plates 304; the product fixing platform 201 has a hollowed-out middle section along the front-back direction, and its left inner wall has a left slot 2011 for the left L-shaped buckle 307 to be elastically fastened from right to left, and its right inner wall has a right slot (not shown) for the right L-shaped buckle 307 to be elastically fastened from left to right.

[0132] When the two L-shaped buckles 307 are snapped into the left slot 2011 and the right slot (not shown), the product pressure plate 30 and the product fixing platform 201 are fixed together.

[0133] Specifically, initially, the two telescopic springs 305 on both sides apply pressure, causing the two movable plates 304 to be positioned inside and outside the two movable slots 303 respectively. Subsequently, the thrust testing component 40 is moved backward, and then the accompanying drawings of this application are... Figure 1The frame 2000 of the virtual reality glasses, in which a small light-transmitting film 1000 is fixedly heat-pressed into the inner surface of the preset opening groove 10, is fixed to the outside of the product fixing platform 201. Then, the operator grips the two handles 306 with both hands to drive the two movable plates 304 to move towards each other in the left and right directions for a preset distance, and presses the product pressure plate 30 of this application onto the frame 2000 and keeps it stationary. Subsequently, the operator releases the two handles 306, and the telescopic springs 305 on both sides automatically return to their original positions, so as to push the left L-shaped buckle 307 on the left side to elastically snap into the left slot 2011 from right to left, and push the right L-shaped buckle 307 on the right side to elastically snap into the right slot (not shown) from left to right. In this way, the two L-shaped buckles 307 are correspondingly snapped into the left slot 2011 and the right slot (not shown), so that the product pressure plate 30 and the product fixing platform 201 are fixed together.

[0134] After the small light-transmitting sheet 1000 has undergone a thrust test, the operation is reversed. The operator grips the two handles 306 with both hands again to drive the two movable plates 304 to move towards each other in the left and right directions for a preset distance. At this time, the product pressure plate 30 can be removed vertically upwards to facilitate the subsequent removal of the frame 2000 of the virtual reality glasses, which has the small light-transmitting sheet 1000 fixed in the preset opening groove 10 on the inner surface after the thrust test, from the product fixing table 201.

[0135] For the above operation, when the product pressure plate 30 is fixed to the product fixing platform 201, there is no need to use fastening bolts or other components, nor is there a need to use tools to fix them to each other. It is only necessary to manually or by using a robotic arm to operate the two handles 306. The operation is simple, convenient and effortless.

[0136] Therefore, through the above-mentioned optimized design, the overall performance of this application can be optimized.

[0137] It should be added that, in a specific implementation, according to an embodiment of the present invention, the product pressure plate 30 of this application is further provided with two detachable cover plates 308 for correspondingly fixing the two movable plates 304;

[0138] Based on this, in this embodiment, each of the two movable grooves 303 includes an upper limit groove 3031, a middle sliding groove 3032, and a bottom opening 3033; the outer half of the bottom of each of the two upper limit grooves 3031 is respectively provided with a middle sliding groove 3032 downward, and the middle part of the bottom of each of the two middle sliding grooves 3032 is respectively provided with a bottom opening 3033 downward; the two movable plates 304 are correspondingly and slidably mounted in the two middle sliding grooves 3032, and their lower bottom periphery is supported by the lower bottom periphery of the two middle sliding grooves 3032, and their inner sides are respectively fixed with the telescopic springs 305 facing inward, and the inner ends of the two telescopic springs 305 abut against the inner sidewalls of the two middle sliding grooves 3032;

[0139] The two handles 306 are fixedly mounted on the outer side of the upper end face of the two movable plates 304, facing upwards respectively; the two L-shaped buckles 307 extend downwards from the two bottom openings 3033 respectively; the two detachable cover plates 308 are detachably snapped into the two upper limit slots 3031 respectively, and the outer middle part of each of them is provided with a relief opening 3081 that penetrates through the upper and lower end faces. When the two handles 306 are gripped in opposite directions, they can slide inwards along the two relief openings 3081 respectively.

[0140] Preferably, in this technical solution, the two detachable cover plates 308 are detachably fixed in the two upper limit slots 3031 by fastening bolts. Thus, when the two detachable cover plates 308 are disassembled, the two movable plates 304 and the two telescopic springs 305 can be disassembled and removed, so that the two telescopic springs 305 can be easily replaced when they lose their elasticity.

[0141] It should also be added that, in a specific implementation, according to an embodiment of the present invention, a guide post 202 is respectively provided on the left and right sides of the upper end face of the product fixing platform 201; a guide hole 309 is respectively provided on the left and right sides of the product pressure plate 30, penetrating its upper and lower end faces; the two guide holes 309 are positioned directly opposite the two guide posts 202, so as to accommodate the two guide posts 202 to be inserted from bottom to top with an interference fit.

[0142] Therefore, when the product pressure plate 30 presses and fixes the mirror frame 2000 framed outside the product fixing platform 201, the two guide posts 202 will be inserted into the two guide holes 309 with an interference fit. In this way, the product pressure plate 30 is pressed and positioned in the vertical direction, so that it is not easy to shift circumferentially during the pressing process, so that it is stable and reliable in use.

[0143] It should be noted that, as specifically shown, an opening groove 10 is provided on the left and right sides of the inner surface of the frame 2000, and a small light-transmitting sheet 1000 is hot-pressed and fixed in each of the two opening grooves 10. Correspondingly, the thrust testing component 40 of this application is provided in two, and is fixed on the left and right sides of the upper end surface of the product fixing base 20 in the front-back direction, so as to perform thrust testing on the small light-transmitting sheets 1000 hot-pressed and fixed in the two opening grooves 10.

[0144] Other embodiments, etc., will not be described here.

[0145] In summary, the thrust testing fixture 3000 for eyeglasses provided in this application can be used to fix the frame 2000 of virtual reality glasses, in which a small light-transmitting film 1000 is hot-pressed and fixed in the pre-set opening groove 10 on the inner surface, and to perform a thrust test on the corresponding hot-pressed small light-transmitting film 1000. After hot-pressing, a preset force can be applied to it through the thrust test to evaluate the firmness of its hot-pressing fixation. In this way, products that pass the above thrust test can proceed to the subsequent processes and finally be manufactured into products for sale, which can greatly reduce the number and probability of products being returned to the factory for repair due to detachment in the future.

[0146] Furthermore, by setting the pressure sensor 404, this application can effectively detect the thrust value of the push member 405 applied to the small light-transmitting sheet 1000 that is hot-pressed and fixed in the opening groove 10. This allows the thrust value to be flexibly adjusted according to actual needs when the application is used to perform thrust tests on the corresponding hot-pressed and fixed small light-transmitting sheet 1000.

[0147] Meanwhile, the counterforce on the pressure sensor 404 described in this application increases gradually, rather than instantaneously, resulting in better protection and making it less prone to sudden damage, thus extending its service life. Furthermore, when the pressure plate 30 of the product described in this application presses down on the mirror frame 2000, the multiple elastic pressure-relieving members 301 buffer the downward pressure, preventing the multiple pressing points of the mirror frame 2000 from being crushed or cracked, thus enhancing the reliability of this application.

[0148] Furthermore, through the aforementioned optimized design, the entire product constituted by this application is indeed highly practical and has an excellent user experience. In the entire manufacturing process of virtual reality glasses, it can provide higher quality assurance and guarantee for the product, making this application effective and easy to promote and popularize.
