Description

Technical Field

[0001] This invention belongs to the field of head-mounted display technology, and specifically relates to a gravity-assisted snap-fit ​​combined head-mounted display optical device. Background Technology

[0002] Head-mounted displays, as an important carrier of extended reality (XR) technologies such as virtual reality (VR) and augmented reality (AR), are receiving increasing attention and being applied in multiple fields.

[0003] A search revealed that Chinese Patent Publication No. CN120909006B, published on January 30, 2026, discloses a head-mounted display device, relating to the field of smart wearable technology. The head-mounted display device includes a housing, two optical modules, and an adjustment assembly. A receiving cavity is formed within the housing. The two optical modules are spaced apart in the left-right direction and movably mounted within the receiving cavity. Each optical module includes a lens barrel, and each lens barrel has a lens. The adjustment assembly extends laterally on the side of the two lens barrels away from the lenses. The adjustment assembly includes an adjustment body, a clutch structure, and a first and second mating structures corresponding to each optical module and arranged in the front-back direction. When adjusting the interpupillary distance, the clutch structure controls the first mating structure to engage with the adjustment body and the second mating structure to disengage from the adjustment body.

[0009] Furthermore, the grid assembly includes several sets of grid strips that are equidistantly spaced and move through the housing; in one case, a limiting groove is formed on the side wall of the grid strip away from the developing chamber; the top view of the limiting groove is T-shaped; and a set of connecting strips is provided at the top and bottom of the several sets of side walls near the developing chamber.

[0010] Furthermore, the bottom of the connecting strip is symmetrically provided with two sets of guide blocks; each set of guide blocks is movably fitted with a set of guide rods; one end of each set of guide rods near the guide block is connected to the corresponding inner wall of the housing; the other end of each set of guide rods is provided with a set of return springs; the other end of each set of return springs is connected to the side wall of the connecting strip; the bottom of the partition plate one is symmetrically provided with several sets of air guide holes; the partition plate one is provided with a control main board two; each set of grille assembly two is provided with a set of limiting rods on the side wall away from the connecting housing one; the cross-section of each set of limiting rods is T-shaped and moves through the corresponding set of limiting grooves.

[0011] Furthermore, on the inner wall of the connecting housing one near the head-mounted display device body, two sets of light-shielding plates two are symmetrically provided, which can rotate inward to block several sets of air ducts; on the bottom and top of the side wall of the connecting housing two away from the connecting housing one, several sets of air inlets and exhaust outlets are respectively provided; on the side wall of the connecting housing two away from the connecting housing one, two sets of mounting slots are symmetrically provided; each set of mounting slots is provided with a set of switching components.

[0012] Furthermore, the top of the partition plate two is provided with a heat sink; several sets of heat sink fins are provided on the two side walls of the heat sink; a set of cooling fans is provided on the side of the several sets of heat sink fins on the same side away from the connecting housing one; a data plug is provided on the side wall of the connecting housing one away from the connecting housing two; the data plug is movably inserted into the data slot.

[0013] Furthermore, the switching component includes a rotating shaft; an air filter plate and a mounting frame are connected to the outer wall of the rotating shaft; a ventilation plate is provided at one end of the air filter plate near the mounting frame; several sets of air inlet holes are evenly distributed on the ventilation plate; the top view cross-section of each set of air inlet holes is S-shaped; and a lens is provided inside the mounting frame.

[0015] The beneficial effects of this invention are: By inserting two sets of limiting rods into two sets of limiting slots and applying pressure, several sets of grid strips on grid assembly one and grid assembly two move into the housing and connecting housing one, respectively. This connects the upper space of the remote connection mechanism and the head-mounted display body. As a mounting module, the remote connection mechanism, under gravity, uses T-shaped limiting rods and slots to prevent the mounted part from easily falling off, improving operational stability. Simultaneously, while increasing the equipment load, the overall heat dissipation channel of the head-mounted display body and the remote connection mechanism is altered, improving heat dissipation efficiency and preventing hot air backflow. This also prevents high temperatures from causing jamming and damage to the equipment, improving the performance and lifespan of the head-mounted display. Furthermore, after the remote connection mechanism is mounted, the air filter plate is located in the mounting slot. The air filter plate filters impurities in the air during intake, while several S-shaped air intake holes on the ventilation plate behind the air filter plate not only allow air to enter but also block light, preventing light leakage from affecting the viewing experience. The test revealed that when the air filter is rotated outward by a corresponding angle, the mounting frame can enter the mounting slot, allowing the display module to connect directly to the external environment through the channels opened by light shield 1 and light shield 2 and the lens. This enables the head-mounted display to be used as an augmented reality (AR) device, improving its usability. When the user experiences fatigue, the viewing aperture is blocked by a control baffle, and then a micro air pump pressurizes the liquid reservoir, allowing the eye-relieving solution stored in the reservoir to be sprayed out through several sets of atomizing nozzles, relieving eye fatigue and improving both convenience and comfort. Furthermore, by using a remote connection mechanism that is detachable from the head-mounted display body to receive image signals captured by a flight device, and by receiving image signals directly from the head-mounted display body, this head-mounted display, compared to existing technologies, can be used as flight goggles when the head-mounted display body is connected to the remote connection mechanism, and as viewing goggles when the remote connection mechanism is detached from the head-mounted display body, thus enriching the functionality of the head-mounted display.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] This invention provides a gravity-assisted snap-fit ​​combined head-mounted display optical device, including a head-mounted display body 1. For example, as shown... Figure 1 and Figure 2 As shown, a remote connection mechanism 2 is movably connected to one side wall of the head-mounted display device body 1; a headband mechanism 3 is provided on the top of the head-mounted display device body 1.

[0022] The head-mounted display device 1 can be used directly as a VR device. It can be electrically / signally connected to small and medium-sized computer terminals such as mobile phones, tablets, laptops, and desktop computers to transmit video images from the computer terminal to the head-mounted display device 1 via electrical or wireless signals. When the head-mounted display device needs to be used as flight goggles, the remote connection mechanism 2 is installed on the head-mounted display device 1 to receive flight images captured by drones, racing drones, and other flight equipment and transmit them to the head-mounted display device 1 via electrical or wireless signals. It should be noted that both electrical and signal connections can be used to transmit flight / video image signals, and the relevant connection methods are quite common in the field. Therefore, no limitation is made here, and the structure is not described in detail.

[0023] For example, such as Figure 3 , Figure 4 and Figure 5 As shown, the head-mounted display device body 1 includes a light shield 101 and a housing 102; a developing chamber is provided inside the light shield 101 and the housing 102; a sensor module 103, a display module 104, and a control motherboard 105 are provided inside the developing chamber; two sets of grille assemblies 106 are symmetrically arranged on the inner wall of the housing 102 near the remote connection mechanism 2; two sets of light shields 107 are symmetrically and movably inserted through the inner wall of the housing 102 near the remote connection mechanism 2; and several sets of heat dissipation holes are symmetrically arranged on both side walls of the housing 102. 108; Two sets of heat sinks 109 are symmetrically arranged on the inner walls of both sides of the housing 102; Each set of heat sinks 109 is connected to several sets of corresponding heat dissipation holes 108; Two sets of viewing holes 110 are symmetrically opened on the inner wall of the side of the light shield 101 that is close to the developing chamber; A baffle 111 is provided above the end of the two sets of viewing holes 110 that is away from the developing chamber; Several sets of atomizing nozzles 112 are symmetrically arranged on the inner walls of both sides of the light shield 101; A data slot 113 is opened on the top of the side wall of the housing 102 that is close to the remote connection mechanism 2.

[0024] When the head-mounted display device 1 is used independently without the remote connection mechanism 2, the heat sink 109 dissipates heat from the device through the air extraction and exhaust of the ventilation holes 108 on both sides, as detailed below. Figure 12 As shown, one of the two radiators 109 is in the suction state and the other is in the exhaust state.

[0025] When the head-mounted display is in use, the light shield 101 covers the user's eyes to prevent external light sources from interfering with the viewing effect. The control motherboard 105 is an integrated control device that can realize signal transmission and reception, video processing and other functions. The sensor module 103 includes accelerometers, magnetometers, infrared sensors and other sensors, which are used to detect head rotation and displacement. The display module 104 presents stereoscopic vision through a small display screen in conjunction with an optical system.

[0026] For example, such as Figure 6 and Figure 7 As shown, the grid assembly 106 includes several sets of grid strips 1061 that are equidistantly and movably pass through the housing 102; a limiting groove 1062 is formed on the side wall of one of the grid strips 1061 away from the developing chamber; the limiting groove 1062 has a T-shaped cross-section when viewed from above; a set of connecting strips 1063 is provided at the top and bottom of the several sets of side walls near the developing chamber; two sets of guide blocks 1064 are symmetrically provided at the bottom of the connecting strips 1063; a set of guide rods 1065 is movably sleeved in each set of guide blocks 1064; one end of each set of guide rods 1065 near the guide block 1064 is connected to the corresponding inner wall of the housing 102; a set of return springs 1066 is provided at the other end of each set of guide rods 1065; the other end of each set of return springs 1066 is connected to the side wall of the connecting strip 1063.

[0027] For example, such as Figure 8 and Figure 9 As shown, the remote connection mechanism 2 includes a first connection housing 201 and a second connection housing 202; a first partition plate 203 is provided inside the first connection housing 201; several sets of air guide holes are symmetrically opened at the bottom of the first partition plate 203; a second control main board 204 is provided on the first partition plate 203; two sets of second grille assemblies 205 are symmetrically and movably inserted through the inner wall of the first connection housing 201 near the head-mounted display device body 1; the second grille assembly 205 is located above the first partition plate 203; a set of limiting rods 214 is provided on the side wall of each set of second grille assemblies 205 away from the first connection housing 201; the cross-section of each set of limiting rods 214 is T-shaped and movably inserted through a corresponding set of limiting grooves 1062; two sets of air guide holes that can rotate inward and block several sets of air guide holes are symmetrically provided on the inner wall of the first connection housing 201 near the head-mounted display device body 1. A second light-shielding plate 206; several sets of air inlets 207 and exhaust holes 208 are respectively opened on the bottom and top of the side wall of the second connecting housing 202 away from the first connecting housing 201; two sets of mounting slots are symmetrically opened on the side wall of the second connecting housing 202 away from the first connecting housing 201; a set of switching components 209 is provided in each set of mounting slots; a second partition plate 210 is provided inside the second connecting housing 202; a heat sink 211 is provided on the top of the second partition plate 210; several sets of heat dissipation fins 212 are respectively provided on the two side walls of the heat sink 211; a set of cooling fans 213 is provided on the side of several sets of heat dissipation fins 212 away from the first connecting housing 201 on the same side; a data plug 215 is provided on the side wall of the first connecting housing 201 away from the second connecting housing 202; the data plug 215 is movably inserted into the data slot 113.

[0028] When the head-mounted display needs to be used as flight goggles, by rotating the two sets of limiting rods 214 to a horizontal state, inserting the two sets of limiting rods 214 into the two sets of limiting grooves 1062, and applying pressure, the several sets of grid strips 1061 on the first grid assembly 106 and the second grid assembly 205 move into the housing 102 and the connecting housing 201 respectively, thereby connecting the remote connection mechanism 2 and the upper space of the head-mounted display body 1. Then, the remote connection mechanism 2 is slid down, so that the data plug 215 is inserted into the data slot 113, thereby connecting the remote connection mechanism 2 and the head-mounted display body 1. After the T-shaped limiting rods 214 are inserted into the T-shaped limiting grooves 1062, the remote connection mechanism 2 is not easy to fall off under the action of gravity, and the connection is more stable. Then, the first light shield 107 and the second light shield 206 are controlled to rotate toward the inside of the housing 102 and the connecting housing 201 respectively.

[0029] When the head-mounted display is in operation, the cooling fan 213 starts working. The second light shield 206, located inside the first connecting housing 201, blocks several sets of air vents. Simultaneously, the end of the first light shield 107 furthest from the rotating shaft faces the first control motherboard. Because the upper and lower spaces within the remote connection mechanism 2 are independent, air enters through the switching component 209 and several sets of air inlets 207. It then passes through the channel opened by the second light shield 206 and the first light shield 107, and, guided by the first light shield 107, blows directly onto the first control motherboard 105 to remove heat. Subsequently, some airflow is discharged through the heat sink 109, and the remaining airflow passes through the channel opened by the first grille assembly 106 and the second grille assembly 205. While passing through the remote connection mechanism 2, it removes heat from the second control motherboard 204 on several sets of cooling fins 212, and finally exits through several sets of exhaust holes 208 (specifically as follows). Figure 13 As shown, both heat sinks 109 are in the exhaust state, which allows the head-mounted display to change the airflow when the remote connection mechanism 2 is attached to increase the device power, so as to more efficiently dissipate the internal heat and avoid damage caused by the head-mounted display working in a high-temperature environment. This allows the head-mounted display to work more stably. In addition, the several sets of air inlets 207 and exhaust outlets 208 face upward and downward respectively, which can also prevent hot air from flowing back and ensure the heat dissipation effect.

[0030] For example, such as Figure 10 As shown, the switching component 209 includes a rotating shaft 2091; an air filter plate 2092 and a mounting frame 2095 are connected to the outer wall of the rotating shaft 2091; a ventilation plate 2093 is provided at one end of the air filter plate 2092 near the mounting frame 2095; several sets of air inlet holes 2094 are evenly distributed on the ventilation plate 2093; the top view cross section of each set of air inlet holes 2094 is S-shaped; a lens 2096 is provided inside the mounting frame 2095.

[0031] After the remote connection mechanism 2 is mounted on the head-mounted display device of the present invention, the air filter plate 2092 is located in the mounting slot. At this time, the air filter plate 2092 is used to filter impurities in the air during air intake. The several sets of S-shaped air intake holes 2094 on the ventilation plate 2093 behind the air filter plate 2092 can not only allow air to enter, but also block the light from entering, so as to avoid light leakage affecting the viewing experience. When the air filter plate 2092 is rotated outward by a corresponding angle, the mounting frame 2095 can enter the mounting slot, so that the display module 104 can be directly connected to the external environment through the channel opened by the first light shield 107 and the second light shield 206 and the lens 2096, thereby enabling the head-mounted display device to be used as an augmented reality (AR) device and improving the use effect of the head-mounted display device.

[0032] For example, such as Figure 11 As shown, the headband mechanism 3 includes a headband body 301; a soft pad 302 is provided on the side wall of the headband body 301 away from the head-mounted display device body 1; a liquid storage box 303 is movably passed through the top of the headband body 301; several sets of inflatable airbags 304 are arranged in a rectangular array inside the soft pad 302; two sets of strap buckles 305 are symmetrically provided on the two side walls of the headband body 301; several sets of miniature air pumps are provided inside the headband body 301; each set of miniature air pumps is connected to a corresponding set of inflatable airbags 304.

[0033] The strap is fixed to the strap buckle 305. When in use, the strap is worn on the user's head. The wearing status is monitored by the sensor module 103 inside the head-mounted display device 1, and the inflation or deflation of several sets of inflatable airbags 304 arranged in an array is controlled respectively. The wearing posture is changed by changing the volume of the inflatable airbags 304. At the same time, when the user is fatigued, the viewing hole is blocked by the control of the baffle 111. Then, the liquid storage box 303 is pressurized by the micro air pump, so that the eye fatigue relief medicine stored in the liquid storage box 303 can be sprayed out through several sets of atomizing nozzles 112 to relieve the user's eye fatigue. This improves the convenience and comfort of the head-mounted display device.

[0034] By inserting two sets of limiting rods 214 into two sets of limiting grooves 1062 and applying pressure, several sets of grid strips 1061 on grid assembly one 106 and grid assembly two 205 are moved into housing 102 and connecting housing one 201 respectively, thereby connecting the upper space of the remote connection mechanism 2 and the head-mounted display device body 1. As a mounting module, the remote connection mechanism 2 can also ensure that the mounted part will not fall off easily under the action of gravity through the T-shaped limiting rods 214 and limiting grooves 1062, thus improving the stability of the operation. At the same time, while increasing the load of the equipment, by changing the overall heat dissipation channel of the head-mounted display device body 1 and the remote connection mechanism 2, the heat dissipation efficiency is improved while avoiding the backflow of hot air, and preventing the high temperature generated by high load operation from causing jamming and damage to the equipment itself, thus improving the use effect and service life of the head-mounted display device.

[0035] After the remote connection mechanism 2 is mounted on the head-mounted display device of the present invention, the air filter plate 2092 is located in the mounting slot. At this time, the air filter plate 2092 is used to filter impurities in the air during air intake. The several sets of S-shaped air intake holes 2094 on the ventilation plate 2093 behind the air filter plate 2092 can not only allow air to enter, but also block the light from entering, so as to avoid light leakage affecting the viewing experience. When the air filter plate 2092 is rotated outward by a corresponding angle, the mounting frame 2095 can enter the mounting slot, so that the display module 104 can be directly connected to the external environment through the channel opened by the first light shield 107 and the second light shield 206 and the lens 2096, thereby enabling the head-mounted display device to be used as an augmented reality (AR) device and improving the use effect of the head-mounted display device.

[0036] The straps are placed on the user's head, and the wearing status is monitored by the sensor module 103 inside the head-mounted display device 1. The sensor module controls the inflation or deflation of several sets of inflatable airbags 304 arranged in an array. The wearing posture is changed by changing the volume of the inflatable airbags 304. When the user becomes fatigued, the viewing hole is blocked by the control panel 111. Then, the liquid storage box 303 is pressurized by a micro air pump, so that the eye fatigue relief solution stored in the liquid storage box 303 can be sprayed out through several sets of atomizing nozzles 112 to relieve the user's eye fatigue. This improves both the convenience and comfort of the head-mounted display device.

[0037] By using a remote connection mechanism 2 that is detachable from the head-mounted display device body 1 to receive image signals captured by the flight device, and by receiving image signals on the head-mounted display device body 1, this head-mounted display device can be used as flight glasses when the head-mounted display device body 1 is connected to the remote connection mechanism 2, and can be used as viewing glasses when the remote connection mechanism 2 is detached from the head-mounted display device body 1, thus enriching the functionality of the head-mounted display device.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
