Description
Technical Field
[0001] The utility model relates to the technical field of 3D display equipment, and specifically refers to a VR all-in-one machine. Background Art
[0002] With the rapid development of virtual reality technology, all-in-one VR headsets, as portable devices integrating multiple functions such as display, computing, and interaction, have attracted widespread attention and application. They provide users with an immersive virtual reality experience and demonstrate enormous potential for application in a wide range of fields, including gaming, education, healthcare, and industrial design. Currently, all-in-one VR headsets on the market commonly experience overheating during use. Because all-in-one VR headsets integrate high-performance electronic components such as the CPU main control chip, display module, and sensors, these components generate significant heat during operation. To ensure the proper operation of these electronic components and extend the lifespan of the device, a cooling fan is typically installed within the device to dissipate heat. Accordingly, heat dissipation vents are formed on the device to facilitate the discharge of heated air.
[0003] However, the existing heat dissipation structure design of all-in-one VR machines has obvious deficiencies. On the one hand, external light can easily enter the interior of the machine through the heat dissipation ports. When light enters, it will interfere with the imaging of the all-in-one VR machine, affecting the user's visual experience, causing stray light, halos and other phenomena to appear on the screen, reducing the realism and immersion of the virtual reality scene. On the other hand, the existing heat dissipation structure design is not reasonable enough, and the hot air cannot be discharged from the machine in a timely and effective manner. This will cause heat to accumulate inside the machine, causing the internal temperature to rise, which in turn affects the performance and stability of electronic components, and may cause the device to freeze, freeze, and other problems, shortening the service life of the device.
[0004] Therefore, there is an urgent need to design a VR all-in-one machine that can effectively solve the problems of heat dissipation and light interference. Utility Model Content

[0024] Example 1
[0025] When the utility model is implemented, Figures 1 to 6 As shown in the figure, when this all-in-one VR headset is in operation, the main control unit drives the lenses to display images, while the internal electronic components generate heat. The cooling fan activates, collecting the hot air and distributing it through the air collector and air manifold to various cooling vents for exhaust. Furthermore, all components of the device work together to provide users with a comfortable wearing experience and clear imaging.
[0026] Body 1 is the outer shell of the entire all-in-one VR headset, housing and protecting the internal components. It provides a mounting base for other components, ensuring they are stably fixed in their respective positions. Slot 101 is located below body 1 for mounting a rubber nose clip 103. It provides mounting space for rubber nose clip 103, allowing it to be accurately inserted and secured. A magnetic plug 102 is located at the top of rubber nose clip 103. When rubber nose clip 103 is inserted into slot 101, magnetic plug 102 and the metal portion within slot 101 generate magnetic attraction, enabling a quick and stable connection between rubber nose clip 103 and body 1. Users can remove rubber nose clip 103 from slot 101 by applying a certain amount of external force to overcome the magnetic force. The rubber nose clip 103 is connected to slot 101 via magnetic plug 102. When the user wears the VR all-in-one device, the rubber nose clip 103 can fit the user's nose bridge, supporting and stabilizing the device, reducing the shaking of the device during wearing, and improving the wearing comfort and stability. The lens 104 is located at the rear of the body 1 and is connected to the main control device 7 via a wire. The CPU main control chip in the main control device 7 processes the image data and transmits the processed image signal to the lens 104 through an auxiliary control circuit. The lens 104 displays the corresponding virtual reality image based on the received signal, providing the user with an immersive visual experience. The raised surface 105 is located at the rear of the body 1, and the heat dissipation hole 2 804 and the heat dissipation hole 3 805 are provided on the raised surface 105. The design of the raised surface 105 helps to change the layout of the heat dissipation holes and the direction of air flow, making the heat dissipation more efficient. At the same time, the raised surface 105 can also provide a certain amount of installation space and structural support for other components.
[0027] The sponge mask 2 is positioned around the frame of the headset 1. When the user wears the VR headset, the sponge mask 2 contacts the user's face, providing both cushioning and sealing. This reduces the amount of light entering the headset, improving image quality, while also increasing wearing comfort and preventing pressure from the headset frame on the user's face.
[0028] The side straps 3 are symmetrically positioned on either side of the body 1. They connect to the back strap 4 and together form part of the wearing structure. The side straps 3 distribute pressure from the device on the head, ensuring a more stable and comfortable fit. Users can adjust the length of the side straps 3 to accommodate users with different head circumferences. The back strap 4 is horizontally connected between the side straps 3. A head cushion 5 is provided on the back strap 4 to further distribute pressure from the device on the head, enhancing wearing comfort. The back strap 4 and the side straps 3 work together to ensure the device is stably fixed to the user's head. The head cushion 5 is located on the back strap 4. It contacts the back of the user's head, providing soft support, reducing pressure from the device and enhancing wearing comfort. The top strap 6 is connected to the head cushion 5 at one end and to the body 1 at the other. It further distributes pressure from the device on the head, ensuring a more stable fit. Users can adjust the length of the top strap 6 to optimize the fit.
[0029] The main control unit 7 consists of a PCB board equipped with a CPU, a power supply, and auxiliary control circuits. The CPU is responsible for processing various data and instructions, controlling the various functions of the all-in-one VR headset. The power supply provides power to the entire device, while the auxiliary control circuits transmit signals processed by the CPU to various components.
[0030] The cooling fan 8 is located behind the main control unit 7. When the VR all-in-one machine is running, the heat generated by the main control unit 7 and other electronic components will cause the internal temperature of the machine to rise. At this time, the cooling fan 8 starts, generating airflow through rotation, drawing in the hot air from the interior of the machine. The air collection hood 801 is connected to the air outlet of the cooling fan 8. It collects and guides the airflow generated by the cooling fan 8, allowing the airflow to enter the air manifold 802 in a more concentrated manner, thereby improving heat dissipation efficiency. The air manifold 802 has a main inlet 807 on the front, and branch pipes 808 connected to the main inlet 807 are located on the top, side, and bottom. The airflow entering from the air collection hood 801 enters the air manifold 802 through the main inlet 807 and is then distributed to different heat dissipation holes through the branch pipes 808 on the top, side, and bottom. Heat dissipation hole 1 803 is located at the top of the machine body 1. The branch pipe 808 on the top of the air manifold 802 is connected to the heat dissipation hole 1 803 via a sealed pipe 806. Hot air distributed from the gas manifold 802 enters heat dissipation hole 1 803 through a sealed conduit 806 and then exits the body 1, achieving heat dissipation from the top. Heat dissipation hole 2 804 is located on the raised surface 105 at the rear of the body 1, in the middle of the rear portion and above the slot 101. A branch pipe opening 808 on the side of the gas manifold 802 is connected to heat dissipation hole 2 804 via a sealed conduit 806. Hot air enters heat dissipation hole 2 804 through the sealed conduit 806 and then exits the body 1, achieving heat dissipation from the middle of the rear portion. A pair of heat dissipation holes 3 805 are provided, one on each side of the lens 104 and also located on the raised surface 105 at the rear of the body 1. A branch pipe opening 808 at the bottom of the gas manifold 802 is connected to heat dissipation hole 3 805 via a sealed conduit 806. Hot air enters heat dissipation hole 3 805 through the sealed conduit 806 and then exits the body 1, achieving heat dissipation from both sides of the rear portion. Sealed conduit 806 connects the air collector 801, the air manifold 802, and the various cooling vents. This ensures that airflow is leak-free during transmission, ensuring the effectiveness of the cooling system. Sealed conduit 806 is made of a sealing material with excellent sealing properties.
[0031] The main inlet 807 is located on the front of the gas manifold 802 and serves as the airflow entrance. Airflow from the air hood 801 enters the gas manifold 802 through the main inlet 807 and is then distributed. Branch inlets 808 are located at the top, side, and bottom of the gas manifold 802 and communicate with the main inlet 807. The airflow entering the gas manifold 802 is distributed to different heat dissipation holes through the branch inlets 808, achieving multi-directional heat dissipation.
[0032] When the VR all-in-one machine is running, the main control device 7 and other electronic components generate heat, causing the temperature inside the machine to rise. The cooling fan 8 starts, sucking in the hot air and collecting it through the wind collecting hood 801. After the hot air enters the air path branch head 802, it is distributed to the branch pipe openings 808 at the top, side, and bottom through the main port 807, and then transported to the heat dissipation hole 1 803, the heat dissipation hole 2 804, and the heat dissipation hole 3 805 through the sealed pipe 806, and finally the hot air is discharged to the outside of the machine body 1. This multi-directional heat dissipation channel design enables the hot air to be discharged from the machine body in a timely and effective manner, avoiding the accumulation of heat inside the machine body, effectively reducing the temperature inside the machine body, ensuring the normal operation of the internal electronic components, and extending the service life of the equipment.
[0033] The inner walls of heat dissipation holes 1 803, 2 804, and 3 805 are coated with a light-absorbing material. When external light enters the device through the heat dissipation holes, the light-absorbing material absorbs the light, reducing reflection and scattering within the device. This prevents light from interfering with the image displayed by lens 104, reducing the impact of external light on the VR headset's imaging, improving image quality and clarity, and providing users with a better visual experience.
[0034] Example 2
[0035] like Figures 2 to 6 As shown, this embodiment provides an overall workflow. When the user presses the power button on the body, the power supply supplies power to the entire device. The power supply uses a DC-DC step-down chip model LM2596S-5.0, with an input voltage range of 7V-40V, an output voltage of 5V, and a maximum output current of 3A. The power supply converts the input power voltage into a voltage suitable for the operation of various electronic components to power electronic components such as the CPU main control chip. The CPU main control chip uses the Kryo 585 architecture with a maximum main frequency of up to 2.84GHz, and the GPU is Adreno 650.
[0036] As the VR all-in-one machine operates, electronic components such as the CPU in the main control device generate a significant amount of heat. This heat can increase the internal temperature of the machine. In this embodiment, the main control device is also equipped with a matching temperature sensor to detect the internal temperature of the machine. The temperature sensor uses the DS18B20 model, with a measurement range of -55°C to +125°C and an accuracy of ±0.5°C. When the internal temperature exceeds a set threshold, it transmits a temperature signal to the CPU.
[0037] After receiving the temperature signal, the CPU main control chip sends a control signal to the cooling fan 8 to start the cooling fan 8. The cooling fan 8 uses a DC brushless fan with model number NMB-MAT 4715MS-23T-B50, with a rated voltage of 5V, a rated current of 0.2A, a speed of 5000RPM, and an air volume of 3.5CFM.
[0038] After the cooling fan 8 is started, it rotates to generate airflow, drawing the hot air from the interior of the housing 1. The hot air first enters the air collecting hood 801, which is made of plastic and has internal guide grooves that can effectively collect and guide the airflow. The air collecting hood 801 collects and guides the airflow, allowing the airflow to enter the air path branch head 802 in a more concentrated manner.
[0039] The air flow manifold 802 is made of aluminum alloy and has excellent heat dissipation performance. It has a main inlet 807 on the front and branch outlets 808 on the top, side, and bottom that connect to the main inlet 807. Air from the air hood 801 enters the air flow manifold 802 through the main inlet 807 and is then distributed to different heat dissipation holes through branch outlets 808 on the top, side, and bottom.
[0040] The branch pipe opening 808 at the top of the gas branching head 802 is connected to the heat dissipation hole 1 803 through a sealed pipe 806. Hot air enters the heat dissipation hole 1 803 through the sealed pipe 806 and is then discharged outside the body 1, achieving heat dissipation in the top direction. The branch pipe opening 808 on the side of the gas branching head 802 is connected to the heat dissipation hole 2 804 through a sealed pipe 806. Hot air enters the heat dissipation hole 2 804 through the sealed pipe 806 and is then discharged outside the body 1, achieving heat dissipation in the middle direction of the rear. The branch pipe opening 808 at the bottom of the gas branching head 802 is connected to the heat dissipation hole 3 805 through a sealed pipe 806. Hot air enters the heat dissipation hole 3 805 through the sealed pipe 806 and is then discharged outside the body, achieving heat dissipation in the sides of the rear. To prevent hot air from exhausting from heat vents 2 and 3, 805, from blowing directly onto the user's face, raised surfaces 105 are provided on the surface of the housing 1 at these locations. These raised surfaces 105 are curved and conform to the user's face. Heat vents 2 and 3, 805, are positioned offset from the user's face, with heat vent 2 804 facing upward and heat vent 3 805 facing to the sides. This multi-directional heat dissipation channel design allows heated air to be promptly and efficiently discharged from the housing, preventing heat accumulation within the housing and effectively reducing the internal temperature, ensuring the proper functioning of the internal electronic components.
[0041] During the heat dissipation process, external light may enter the interior of the body through the heat dissipation holes. To prevent light interference, the inner walls of heat dissipation hole 1 803, heat dissipation hole 2 804, and heat dissipation hole 3 805 are coated with a light-absorbing material. The light-absorbing material uses a black aluminum oxide coating with an absorbance of more than 95%. When external light enters the interior of the body through the heat dissipation holes, the light-absorbing material can absorb the light and reduce the reflection and scattering of light inside the body. In this way, the light will not interfere with the image displayed on the lens, reducing the impact of external light on the imaging of the VR all-in-one machine, improving the quality and clarity of the picture, and providing users with a better visual experience.
[0042] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
