Description

A heat dissipation structure for a holographic device Technical Field

[0001] This invention relates to the field of holographic device technology, and more specifically to a heat dissipation structure for a holographic device. Background Technology

[0002] A holographic capsule is an advanced device that utilizes virtual reality technology. Its core components include a display screen and a lightbox. The lightbox provides a stable and uniform light source for holographic imaging, ensuring that the holographic image has consistent brightness and clarity from all angles. This reduces differences in image brightness caused by uneven lighting, allowing viewers to see a complete and clear holographic image.

[0003] To protect the structural safety of the internal components and prevent electrical leakage, existing holographic cabin designs typically require a protective outer shell, with the light box installed inside the shell.

[0004] However, in existing technologies, through holes or grilles are usually set on the vertical end face of the outer shell for ventilation and heat dissipation. However, the light box generates a lot of heat when it is in operation, and through holes or grilles alone cannot effectively dissipate heat. If the heat is not dissipated in time, the temperature inside the holographic cabin will rise, which may cause the control system to lag or even be damaged, seriously affecting the user experience. Summary of the Invention

[0005] In view of this, the present invention provides a heat dissipation structure for a holographic device to solve the problem of poor heat dissipation in existing holographic devices.

[0006] This invention provides a heat dissipation structure for a holographic device, comprising: a housing having a receiving cavity, wherein the housing is provided with an air inlet and an air outlet;

[0007] A light box assembly is disposed within the receiving cavity of the housing. A ventilation channel is provided between the outer side of the light box assembly and the inner side of the housing, and the ventilation channel is connected to the air inlet and the air outlet.

[0008] A heat dissipation component is disposed on the air outlet and / or air inlet of the housing, and the heat dissipation component is used to exhaust the heat of the light box component to the outside of the housing through the ventilation channel.

[0009] The housing has an internal cavity, and an air inlet and an air outlet are provided on the housing. The light box assembly is spaced apart from the housing, and the space formed by the gap is a ventilation channel. When heat dissipation is needed, the heat dissipation assembly is activated, and air enters from the air inlet. As the air passes through the ventilation channel, it carries away the heat generated by the light box and then exits from the air outlet. This allows the cool air to carry away the heat from the air inlet and exit at the same time, increasing the heat dissipation effect on the holographic device and thus effectively reducing the internal temperature of the holographic cabin.

[0010] In one optional embodiment, the outer side of the light box assembly and the inner side of the housing are spaced apart to form a plurality of ventilation channels, which are interconnected.

[0011] By designing the gap between the lightbox components and the housing, multiple interconnected ventilation channels are formed, which further enhances the heat dissipation efficiency, ensures that heat is evenly distributed and quickly discharged, effectively avoids local overheating, improves the overall heat dissipation performance of the holographic device, and ensures the long-term stable operation of the device.

[0012] In one alternative embodiment, the air inlet is located on the bottom surface of the housing.

[0013] By placing the air inlet on the bottom surface of the casing and utilizing the principle of rising cold air, the airflow path is optimized, the heat dissipation effect is enhanced, and the internal temperature of the holographic chamber is further reduced, ensuring that the equipment remains highly efficient and stable even under high load.

[0014] In one optional embodiment, the lower end face of the housing cavity is provided with an upwardly protruding boss, and the air inlet is disposed on the boss.

[0015] The raised design of the boss elevates the air inlet, preventing dust from the ground from entering directly and extending the service life of the equipment.

[0016] In one optional embodiment, the light box assembly includes: a plurality of light boxes, which are vertically arranged between adjacent light boxes, and adjacent light boxes are detachably connected by a first fastener.

[0017] By vertically setting two adjacent light boxes and detachably connecting them with the first fixing member, the installation and maintenance of the light box components are facilitated, while space utilization is optimized and heat dissipation of each light box is ensured.

[0018] In one optional embodiment, the light box has a light-emitting element, a ventilation cavity is provided on the light box, the light-emitting element is disposed in the ventilation cavity, and at least one ventilation opening is provided on the light box, the ventilation opening connecting the ventilation cavity and the ventilation channel.

[0019] By setting ventilation openings on the light box, the heat generated inside the light box can be discharged into the ventilation channel through the ventilation cavity and ventilation openings in a timely manner, and then discharged to the outside of the shell through the air outlet, thereby effectively cooling the inside of the light box.

[0020] In one alternative embodiment, the light box has a mounting surface, and the mounting surface of one of two adjacent light boxes abuts against the mounting surface of the other light box, with a mounting cavity for mounting the first fastener formed between the two mounting surfaces.

[0021] By setting mounting surfaces on the light box, a mounting cavity is formed between the mounting surfaces of two adjacent vertically set light boxes. The first fastener is installed into the mounting cavity, which enhances the overall structural stability of the light box assembly and facilitates quick replacement and maintenance.

[0022] In one optional embodiment, the light box includes: a light-emitting element and a mounting plate, the light-emitting element and the mounting plate being arranged in parallel and spaced apart, at least one of the light-emitting element and the mounting plate being provided with a connector, and the ventilation opening being provided on the connector.

[0023] By setting vents on the connectors, heat between the light-emitting components and the mounting plate can be quickly dissipated, preventing heat buildup and improving the heat dissipation effect of the light box.

[0024] In one optional embodiment, the first fastener includes a first connecting plate and a second connecting plate arranged perpendicularly to each other, the first connecting plate and the second connecting plate respectively abutting the outer end faces of two adjacent light boxes, and a fastener passing through the first connecting plate or the second connecting plate and connecting to the light box.

[0025] The first connecting plate connects to one of the light boxes, and the second connecting plate connects to the other light box, thus fixing the two adjacent light boxes together and ensuring a stable connection that is easy to disassemble.

[0026] In one alternative embodiment, the light box located at the bottom of the housing is detachably connected to the housing via a second fastener.

[0027] The second fastener allows for a detachable connection between the light box and the bottom of the housing, facilitating individual maintenance and replacement. Attached Figure Description

Detailed Implementation

[0043] 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.

[0044] The embodiments of the present invention are described below with reference to Figures 1 to 12.

[0045] According to an embodiment of the present invention, as shown in Figures 1 and 2, a heat dissipation structure for a holographic device is provided, comprising: a housing 1, a light box assembly 2, and a heat dissipation assembly 3. The housing 1 has a receiving cavity for mounting the light box assembly 2. The light box assembly 2 provides a stable light source. An air inlet 4 and an air outlet 5 are provided on the housing 1. The light box assembly 2 is disposed within the receiving cavity of the housing 1, and a ventilation channel 6 is provided between the outer side of the light box assembly 2 and the inner side of the housing 1, the ventilation channel 6 communicating with the air inlet 4 and the air outlet 5; the heat dissipation assembly 3 is disposed on the air outlet 5 of the housing 1, and the heat dissipation assembly 3 is used to exhaust the heat of the light box assembly 2 to the outside of the housing 1 through the ventilation channel 6.

[0046] In practice, the lightbox assembly 2 is housed within the casing 1, with a ventilation channel 6 between the lightbox assembly 2 and the casing 1. During heat dissipation, the heat dissipation assembly 3 is activated, drawing air in through the air inlet 4. As the heat dissipation assembly 3 is activated, the air passing through the ventilation channel 6 carries away the heat generated by the lightbox and is then exhausted through the air outlet 5. This allows cool air to escape while simultaneously carrying away heat from the air inlet 4, increasing the heat dissipation effect on the holographic device and effectively reducing the internal temperature of the holographic chamber. Alternatively, the heat dissipation assembly 3 can also exhaust hot air through the air outlet 5.

[0047] Specifically, the heat dissipation component 3 can also be installed on the air inlet 4 to blow air into the housing 1. Alternatively, the heat dissipation component 3 can be installed on both the air inlet 4 and the air outlet 5 to form a two-way ventilation system and further optimize heat dissipation efficiency.

[0048] Specifically, the heat dissipation component 3 includes an exhaust fan for enhancing heat dissipation. The exhaust fan is bolted to the housing 1 to ensure that the heat dissipation component 3 can be stably positioned at the air outlet 5 or air inlet 4 of the housing 1.

[0049] As shown in Figures 3 and 4, in this embodiment, the outer side of the light box assembly 2 is spaced apart from the inner side of the housing 1, forming multiple ventilation channels 6. That is, ventilation channels 6 are provided on the side and top of the light box assembly 2, forming multiple interconnected ventilation channels 6. When the heat dissipation assembly 3 is activated, air enters from the air inlet 4. As the air passes through the side and top of the light box assembly 2, it carries away the heat from the light box assembly 2, thereby reducing the temperature of the light box assembly 2, further enhancing the heat dissipation efficiency, ensuring uniform heat distribution and rapid exhaust, and effectively avoiding localized overheating. It should be noted that, as an alternative implementation, the light box assembly 2 may not be spaced apart from the inner side of the housing 1, but instead protrude outwards on the housing 1 to form a groove. The groove forms a ventilation channel, and both ends of the groove are connected to the air inlet 4 and the air outlet 5, respectively. The heat dissipation assembly 3 carries away the heat from the light box assembly 2 as air flows through the groove.

[0050] As shown in Figures 5 and 6, in this embodiment, the air inlet 4 is located on the bottom surface of the housing 1, and the air outlet 5 is located on the side surface of the housing 1. The heat dissipation assembly 3 is located on the air outlet 5. When the heat dissipation assembly 3 is activated, air enters the housing 1 through the air inlet 4, passes through the side and top ventilation channels 6 of the light box assembly 2, carries away heat, and is discharged from the air outlet 5, forming a highly efficient circulating heat dissipation system. By placing the air inlet 4 on the bottom surface of the housing 1, the airflow path is optimized by utilizing the principle of rising cold air, enhancing the heat dissipation effect, further reducing the internal temperature of the holographic chamber, and ensuring that the equipment remains highly efficient and stable even under high load operation. It should be noted that the air outlet 5 can also be located on the top surface of the housing 1.

[0051] Specifically, the air inlet 4 is a round hole, and the air outlet 5 is a rectangular hole. The air inlet 4 and the air outlet 5 penetrate the shell 1.

[0052] As shown in Figure 6, in this embodiment, multiple rows of air inlets 4 are arranged on the lower end face of the housing 1, with multiple air inlets 4 arranged in each row. Through the arrangement of multiple air inlets 4, multiple air inlets 4 are connected to multiple ventilation channels 6, realizing an all-round heat dissipation path, further improving heat dissipation efficiency, and ensuring that the holographic device can maintain good heat dissipation performance in different usage environments.

[0053] Specifically, the air inlets 4 are located at both ends of the length of the housing 1.

[0054] As shown in Figure 6, in this embodiment, the lower end face of the receiving cavity of the housing 1 is provided with an upward protrusion 7, that is, the lower end face of the protrusion 7 is a groove. The protrusion 7 can raise the lower end face of the housing 1. After the air inlet 4 is set on the protrusion 7, the position of the air inlet 4 is raised, which prevents dust from the ground from entering directly and extends the service life of the equipment.

[0055] Specifically, the lower end face of the housing 1 is provided with multiple rollers. The rollers are used to support and move the housing 1, facilitating the rapid deployment of the equipment in different locations. At the same time, the rollers create a gap between the housing 1 and the ground or supporting surface, allowing air to enter the interior of the housing 1 through the air inlet 4.

[0056] As shown in Figures 7 and 9, in this embodiment, the light box assembly 2 includes multiple light boxes, with adjacent light boxes arranged vertically. Adjacent light boxes are detachably connected by a first fixing member 8. By arranging adjacent light boxes vertically and detachably connecting them via the first fixing member 8, the installation and maintenance of the light box assembly 2 are facilitated, while also optimizing space utilization and ensuring uniform heat dissipation for each light box. It should be noted that the light boxes can also be directly fixed together using bolts.

[0057] Specifically, the lightbox assembly 2 includes five lightboxes arranged to form a rectangular frame. One side of the rectangular frame is open for mounting the display screen 9. The lightboxes are connected in pairs via a first fastener 8. Furthermore, the number of lightboxes can be adjusted according to actual needs, ensuring the flexibility and adaptability of the lightbox assembly 2.

[0058] Specifically, the first fixing member 8 includes a first connecting plate and a second connecting plate arranged perpendicularly to each other. The first connecting plate and the second connecting plate are respectively attached to the outer end faces of two adjacent light boxes, and fasteners pass through the first connecting plate and the second connecting plate respectively and are connected to the light boxes. Specifically, the fasteners are bolts. The first connecting plate and the second connecting plate are provided with mounting holes, and the bolts pass through the mounting holes and are threaded to the light boxes. By connecting to one light box through the first connecting plate and to the other light box through the second connecting plate, the two adjacent light boxes are fixedly connected, ensuring a stable connection and easy disassembly. It should be noted that, as an alternative implementation, the first fixing member 8 can also be a rectangular plate, with two sides of the rectangular block respectively attached to the two light boxes, and bolts passing through the rectangular block and being threaded to the light boxes.

[0059] Specifically, the mounting holes are elongated, allowing for easy adjustment of the bolts within the holes to accommodate different light box spacings and enhance connection stability.

[0060] As shown in Figure 11, in this embodiment, the light box has a light-emitting element 10, which generates a light source. The light-emitting element 10 generates a large amount of heat during operation. A ventilation cavity 11 is provided on the light box, and the light-emitting element 10 is disposed within the ventilation cavity 11. At least one ventilation opening 12 is provided on the light box, connecting the ventilation cavity 11 and the ventilation channel 6. When the light-emitting element 10 generates heat, the heat enters the ventilation channel 6 through the ventilation cavity 11 and the ventilation opening 12, and is then discharged outside the housing 1 through the ventilation channel 6, thereby reducing the heat generated by the light-emitting element 10 inside the light box. It should be noted that, as an alternative implementation, multiple ventilation openings 12 can also be provided on the light box, such as two or three.

[0061] As shown in Figure 8, in this embodiment, since multiple light boxes are provided, they need to be integrated into a whole by means of a first fixing member 8. Therefore, the light box has a mounting surface 13, and the first fixing member 8 fixes two light boxes through the two mounting surfaces 13 of two adjacent light boxes. Specifically, the mounting surface 13 of one of the two adjacent light boxes partially abuts against the mounting surface 13 of the other light box. At this time, a mounting cavity for installing the first fixing member 8 is formed between the two mounting surfaces 13 of the light box. By setting the mounting cavity, the first fixing member 8 is installed, ensuring a simple and efficient installation process.

[0062] Specifically, when the horizontally set light box and the vertically set light box are installed by the first fixing member 8, the mounting surface 13 of the horizontally set light box is the side, and the mounting surface 13 of the vertically set light box is the top or bottom surface. The vertically set light box is attached to the mounting surface 13 of the horizontally set light box. At this time, the mounting surface 13 of the horizontally set light box and the mounting surface 13 of the vertically set light box are perpendicular to each other, and a mounting cavity is formed between the two mounting surfaces 13. The first connecting plate and the second connecting plate of the first fixing member 8 are respectively attached to the two mounting surfaces 13, and are connected to the two light boxes after the fastener passes through the two connecting plates.

[0063] Specifically, between two vertically arranged light boxes, the mounting surface 13 is a vertical surface along the width direction of the light box. When they are attached, one light box is placed against the mounting surface 13 of the other light box, and the mounting surfaces 13 of the two light boxes are perpendicular to each other. The first fixing member 8 is installed on the two mounting surfaces 13 of the two light boxes for fixation. In summary, the fixed connection between the five light boxes is completed, thereby achieving the overall installation of the light boxes.

[0064] As shown in Figure 11, in this embodiment, the light box includes a light-emitting element 10 and a mounting plate 15. The light-emitting element 10 is used to emit light. The mounting plate 15 is used to fix the light-emitting element 10. The light-emitting element 10 and the mounting plate 15 are arranged parallel to each other and spaced apart, forming a ventilation cavity 11. At least one of the light-emitting element 10 and the mounting plate 15 is provided with a connector 17, and the light-emitting element 10 and the mounting plate 15 are detachably connected by the connector. A vent 12 is provided on the connector 17. When the light-emitting element 10 heats up, the generated heat enters the ventilation channel 6 through the ventilation cavity 11 and the vent 12. By spaced apart between the light-emitting element 10 and the mounting plate 15 to form the ventilation cavity 11, the heat generated by the light-emitting element 10 can be discharged to the ventilation channel 6 for heat dissipation to the greatest extent possible through the ventilation cavity 11.

[0065] Specifically, as shown in Figure 12, four connectors 17 are provided between the light-emitting element 10 and the mounting plate 15, and are respectively installed on the four sides of the mounting plate 15. The outer end face of the connector 17 is the mounting surface 13. The cross-section of the connector 17 is "C" shaped, including: two parallel and spaced connecting plates and a vertical plate disposed between the connecting plates. During installation, the opening of the connector 17 faces the inside of the light box, and the bolt passes through the connecting plate and is threadedly connected to the light-emitting element 10 or the mounting plate 15.

[0066] As shown in Figure 8, in this embodiment, the light box located at the bottom of the housing 1 is detachably connected to the housing 1 via a second fastener 16. The second fastener 16 allows for a detachable connection between the light box and the bottom of the housing 1, facilitating individual maintenance and replacement.

[0067] Specifically, the light box located at the bottom of housing 1 is horizontally positioned within the receiving cavity of housing 1. Three light boxes and a display screen 9 are respectively positioned on the four sides of the upper end of the bottom light box. The second fixing member 16 includes: a third connecting plate, a fourth connecting plate, and a fifth connecting plate arranged parallel to each other. The two ends of the fifth connecting plate along its length are fixedly connected to the third and fourth connecting plates, respectively. The third, fourth, and fifth connecting plates are integrally formed. Fasteners pass through the first connecting plate and connect to the light box, pass through the second connecting plate and connect to the other light box, and pass through the fifth connecting plate and connect to housing 1. Specifically, the fasteners are bolts. During installation, the light box is placed horizontally inside housing 1. The fifth connecting plate of the second fixing member 16 is placed against one vertical end face of the light box. After the fastener passes through the fifth connecting plate, it is threadedly connected to the light box. Then, the bolt passes through the fourth connecting plate and is fixedly connected to housing 1. The other light box is set vertically, with its lower end face placed on the third connecting plate. The bolt passes through the third connecting plate and is threadedly connected to the vertically set light box.

[0068] By setting a fifth connecting plate between the third and fourth connecting plates, which connects to both the light box and housing 1, the stability of the overall structure is enhanced, ensuring efficient heat dissipation and reliable equipment operation even in complex environments. It should be noted that the second fixing component 16 can also be a bolt. A horizontally outward-facing connecting plate is provided on the light box at the bottom of housing 1, and the bolt passes through the connecting plate and is threaded into housing 1.

[0069] Specifically, as shown in Figure 10, a third fixing member 14 is detachably installed on the light box or the first fixing member 8 located on the top of the housing 1. The light box is detachably connected to the top or side of the housing 1 through the third fixing member 14. Specifically, the third fixing member 14 includes two parallel members. Through the flexible arrangement of the third fixing member 14, convenient connection between the light box and the top or side of the housing 1 is achieved, further improving the overall stability and ease of maintenance of the equipment.

[0070] The third fastener 14 includes a vertically arranged sixth connecting plate, with a seventh connecting plate and an eighth connecting plate extending in opposite directions horizontally at the upper and lower ends of the sixth connecting plate, respectively. During installation, the seventh connecting plate rests against the upper surface of the light box, and the eighth connecting plate rests against the upper surface of the housing 1. Fasteners pass through the seventh connecting plate and are threaded into the light box, and fasteners pass through the eighth connecting plate and are threaded into the housing 1. Alternatively, the seventh connecting plate can also rest against the first fastener 8 and be threaded into the first fastener 8 via fasteners.

[0071] Installation method of the heat dissipation structure of the holographic device: Place the housing 1 in a predetermined position to ensure its stability. Next, use the second fixing member 16 to detachably connect the light box located at the bottom of the housing 1 to the bottom of the housing 1. Then, use the first fixing member 8 to vertically set two adjacent light boxes and assemble them using a detachable connection, ensuring the overall stability of the light box assembly 2. After the light box assembly 2 is installed, place it entirely into the receiving cavity of the housing 1, ensuring that the outer side of the light box assembly 2 is spaced apart from the inner side of the housing 1 to form a ventilation channel 6. Finally, install the heat dissipation components 3 on the air inlet 4 and air outlet 5 of the housing 1 as needed, completing the installation of the entire heat dissipation structure.

[0072] The working principle of the heat dissipation structure of the holographic device: The heat dissipation structure of the holographic device mainly includes a housing 1, a light box assembly 2, and a heat dissipation component 3. During operation, the light box assembly 2 is housed within the cavity of the housing 1. The light box assembly 2 provides a stable light source and generates heat during operation. To effectively dissipate this heat, the housing 1 is provided with an air inlet 4 and an air outlet 5. Ventilation channels 6 are provided between the outer surface of the light box assembly 2 and the inner surface of the housing 1, and these ventilation channels 6 are connected to the air inlet 4 and the air outlet 5.

[0073] When the heat dissipation component 3 is activated, air enters the housing 1 through the air inlet 4, carries away the heat generated by the light box component 2 as it passes through the ventilation channel 6, and then exits through the air outlet 5, thus achieving heat dissipation. This design allows cool air to continuously enter through the air inlet 4, carrying away heat while simultaneously expelling it, increasing the heat dissipation effect on the holographic device and effectively reducing the internal temperature of the holographic cabin.

[0074] Specifically, the heat dissipation component 3 can be installed on the air outlet 5 for exhausting hot air from inside the housing 1; it can also be installed on the air inlet 4 for blowing air into the housing 1; or, heat dissipation components 3 can be installed on both the air inlet 4 and the air outlet 5 to form a two-way ventilation system, further optimizing heat dissipation efficiency. Furthermore, the design of the air inlet 4 and the air outlet 5 has also been optimized. The air inlet 4 is located on the bottom surface of the housing 1, and the air outlet 5 is located on the side surface of the housing 1. Utilizing the principle of rising cold air, the airflow path is optimized, enhancing the heat dissipation effect. Simultaneously, multiple rows of air inlets 4 are arranged on the lower surface of the housing 1, with multiple air inlets 4 in each row, achieving an all-around heat dissipation path and further improving heat dissipation efficiency.

[0075] In summary, the heat dissipation structure of the holographic device, through the reasonable design of the air inlet 4, air outlet 5 and ventilation channel 6, as well as the activation of the heat dissipation component 3, effectively dissipates the heat generated by the light box component 2, ensuring that the holographic device remains highly efficient and stable even under high load operation.
