The technical solution uses spotlights to give people a strong sense of presence and give people a visual impact. Spotlights are one of the light source systems in the integrated imaging three-dimensional display device.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-5The utility model provides an embodiment: a heat dissipation structure of an integrated imaging three-dimensional display device, comprising an outer support tube 1 and inner annular support sleeves 1 2 and 3 of the same structure fixed at two port positions inside the outer support tube 1.

Therefore, the support sleeves made of aluminum alloy can reduce the weight of the entire device.

[0021] The interiors of the inner annular support sleeve 1 2 and the inner annular support sleeve 2 3 are both provided with a plurality of equally spaced dual-axis sinking cavities 4, and the interior of the dual-axis sinking cavity 4 is provided with a gear-type turbine air intake structure 6 for guiding external air into the interior of the outer support tube 1, and the bottom end of the inner annular support sleeve 1 and the top end of the inner annular support sleeve 2 3 are both provided with a planetary gear transmission structure 7 for power connection with the plurality of gear-type turbine air intake structures 6, a transmission shaft 5 is installed on one side of the top end of the inner annular support sleeve 2, and the two ends of the transmission shaft 5 are connected to one of the gear-type turbine air intake structures 6 inside the inner annular support sleeve 1 and the inner annular support sleeve 2 3, a rectangular cavity is provided on one side of the interior of the inner annular support sleeve 2, and a rotation drive unit 8 for driving the transmission shaft 5 to rotate is provided inside the rectangular cavity;

[0022] The rotary power of the rotary drive unit 8 is first transmitted to the transmission shaft 5. At this time, the two ends of the transmission shaft 5 respectively drive one of the gear-type turbine air intake structures 6 in the inner annular support sleeve 1 2 and the inner annular support sleeve 2 3 to move, and the remaining gear-type turbine air intake structures 6 will rotate together under the power connection of the planetary gear transmission structure 7;

[0023] The inner annular support sleeve 1 is provided with a guide groove 201 inside, and the guide groove 201 is used to connect the dual-axis body sinking cavity 4 and the accommodating cavity 202. The accommodating cavity 202 provides space for the installation of the spotlight, so that the outer support tube 1, the inner annular support sleeve 1 and the spotlight can be smoothly installed and connected;

[0024] The rotation drive unit 8 includes a stepper motor 801 installed in a rectangular cavity, and a bevel gear transmission structure 802 installed at the output end of the stepper motor 801 for driving the transmission shaft 5 to rotate. During the operation of the gear-type turbine air intake structure 6, the stepper motor 801 drives the transmission shaft 5 to rotate through the bevel gear transmission structure 802, so that one of the gear-type turbine air intake structures 6 in the inner annular support sleeve 1 2 and the inner annular support sleeve 2 3 is driven to move, and the planetary gear transmission structure 7 plays a role in connecting the remaining gear-type turbine air intake structures 6. At this time, several gear-type turbine air intake structures 6 in the inner annular support sleeve 1 2 and the inner annular support sleeve 2 3 move together, thereby realizing the synchronous action function of one motor driving multiple air intake structures, and the structure is simple and the operation is stable and reliable;

[0025] The gear-type turbine air intake structure 6 includes a driving shaft 601 and a driven shaft 602 rotatably mounted inside the double-shaft body sinking cavity 4, a turbine fan unit 603 is fixed to the top of the driven shaft 602, a gear transmission structure 604 for power transmission is installed between the driving shaft 601 and the driven shaft 602, and the planetary gear transmission structure 7 includes an inner gear ring 702 rotatably mounted at the bottom end of the inner annular support sleeve 2, and an outer gear 701 fixed at the bottom end of the driving shaft 601, and the outer gear 701 and the inner gear ring 702 are meshed with each other;

[0026] During the operation of the gear-type turbine air intake structure 6, the inner gear ring 702 drives the outer gear 701 and the driving shaft 601 to rotate, and the driving shaft 601 drives the driven shaft 602 and the turbofan unit 603 to rotate through the gear transmission structure 604. At this time, the turbofan unit 603 will guide the external low-temperature air into the interior of the spotlight, that is, the air is sent into the accommodating cavity 202 through the guide groove 201 and contacts and exchanges heat with the spotlight. This airflow guiding method can ensure that the low-temperature air fully contacts the surface of the spotlight, realize rapid heat exchange, and improve the heat dissipation efficiency.

The fixing method can use a cable tie or an adhesive tape to tighten the outer support tube 1 and the spotlight shell. After the structure is connected to the spotlight shell, the staff energizes the rotation drive unit 8 and starts it to work. The rotational power of the rotation drive unit 8 is first transmitted to the transmission shaft 5. At this time, the two ends of the transmission shaft 5 each drive a gear-type turbine air intake structure 6 in the inner annular support sleeve 1 2 and the inner annular support sleeve 2 3 to move, and the remaining gear-type turbine air intake structures 6 will rotate together under the power connection of the planetary gear transmission structure 7, and then utilize The gear-type turbine air intake structure 6 introduces low-temperature air in the surrounding environment into the inner annular support sleeve 2 and the outer support tube 1. In this process, the guide groove 201 serves as a channel for air flow, so that the low-temperature air is introduced into the inside of the spotlight or surrounds the outside of the spotlight, and effectively exchanges heat with the heat generated by the spotlight. In this way, the temperature of the spotlight can be quickly reduced, thereby improving the heat dissipation efficiency. Compared with the heat dissipation design that simply relies on the spotlight's own shell, the method of actively introducing external low-temperature air can dissipate heat more quickly and effectively, so that the temperature of the spotlight can be effectively controlled and reduced. Through effective heat dissipation design, it can be ensured that each component in the spotlight operates within a suitable operating temperature range, thereby improving the working performance and imaging stability of the entire three-dimensional stereoscopic display device.
