Description

Technical Field

[0001] This invention relates to the field of display technology, and in particular to an LED transparent display screen and its manufacturing process. Background Technology

[0002] LED transparent displays are display devices that integrate micro LED light-emitting units based on transparent substrate materials (such as glass or flexible polymers). They achieve image display functions through arrayed or grid-like self-emissive pixel units, with pixel pitch typically less than 1 mm and light transmittance ranging from 50% to 90%. Each LED can independently control its brightness and color, forming a continuous image through drive circuitry. This structure maintains basic light transmittance while possessing high contrast, wide color gamut, and fast response characteristics. Its transparency allows ambient light to penetrate and superimpose on the displayed content, creating a visual effect that blends reality and illusion. It is mainly used in commercial displays, architectural media facades, vehicle head-up displays, and intelligent interactive terminals. As a new display technology, it combines a transparent substrate with miniaturized LEDs, expanding the integration of display devices with their usage environment while maintaining display functionality.

[0003] Traditional outdoor LED transparent display screen equipment lacks a dynamic center of gravity adjustment mechanism in its base structure supporting the LED transparent display screen. When applied to large-size display modules, it is difficult to achieve stable positioning through mechanical balance optimization of the support system. Especially during equipment transportation, the display components are prone to tilting or even tipping over due to inertia. Secondly, the equipment's heat dissipation channels and dustproof structures are not effectively designed in synergy. Existing technology only achieves passive air convection through heat dissipation holes, but lacks active dustproof measures when not in operation. This allows particulate matter in the environment to enter the equipment along the heat dissipation path. Long-term accumulation can cause problems such as oxidation of electronic component pins and deterioration of circuit board insulation performance, which can easily affect the environmental adaptability and operational reliability of outdoor LED transparent display screen equipment. Summary of the Invention

Each drive gear is meshed with the follower rack, and the push-pull plate is connected to the follower rack.

[0008] Preferably, the extension mechanism includes a gear positioning shaft, an extension arm, planetary gears, and a first brake caster. The gear positioning shaft is connected to the supporting frustum. The extension arm and the gear positioning shaft are rotatably connected via bearings. The planetary gears are fixedly installed on the lower surface of the extension arm and located at the gear positioning shaft position. The first brake caster is installed on the lower surface of the extension arm and away from the gear positioning shaft position. The planetary gears are coaxial with the gear positioning shaft, and each planetary gear meshes with a sun gear.

[0009] Preferably, a flat key is fixedly provided on the outer surface of the first drive shaft at the position of the sun gear for driving the sun gear and the first drive shaft to rotate synchronously. The inner surface of the first drive shaft is threaded with internal threads, and a stud is provided on the inner surface of the first drive shaft through thread engagement.

[0010] Preferably, the auxiliary mechanism further includes a drive worm and a worm drive motor located outside the drive worm wheel. Two worm mounting seats are respectively provided at both ends of the drive worm. The worm mounting seats are connected to the supporting frustum. The drive worm and the worm mounting seats are rotatably configured via bearings. The drive worm is meshed with the drive worm wheel. The outer end of the drive worm is connected and assembled with the output end of the worm drive motor via a coupling.

[0011] Preferably, two first electric telescopic rods are respectively installed on the inner walls of both sides of the upper surface of the supporting cylindrical platform.

[0013] A manufacturing process for an LED transparent display screen includes the following steps: Step 1: When adjusting the orientation of the LED transparent display module, rotate the reversing platform. The reversing platform is rotatably connected to the lifting platform through the second drive shaft. During the rotation, the reversing platform drives the casing adapter, the display casing and the internal LED transparent display module to rotate synchronously for multi-angle adjustment. After the adjustment is completed, lock the second brake universal wheel to fix the orientation of the LED transparent display module. Step 2: Start the worm drive motor in the auxiliary mechanism to drive the worm to rotate and drive the meshing drive worm wheel to rotate. The worm wheel then drives the sun gear to rotate through the first drive shaft. The sun gear meshes with the planetary gear and pushes the extension arm to unfold outward around the gear positioning axis, so that the first brake caster touches the ground. At this time, the interceptor plate prevents the extension arm from retracting excessively and colliding with the sun gear. Step 3: When the internal temperature of the LED transparent display module rises, activate the second electric telescopic rod to push the push-pull plate to slide along the guide rail, causing the follower rack to rise and fall. The follower rack meshes with the drive gear, driving the crossbar to rotate and open the flip plate. The sealing strip ensures the sealing of the joint. At this time, the exhaust fan accelerates the discharge of hot air from inside the display case through the back opening. After heat dissipation is completed, reverse the operation of the second electric telescopic rod to close the flip plate to prevent external dust from entering.

[0014] The beneficial effects of this invention are: By setting up an extension mechanism, a drive worm gear, a sun gear, and a first drive shaft, and utilizing mechanical transmission and support extension techniques, dynamic center of gravity adjustment and stable positioning are achieved, solving the problem of tilting during transport caused by the lack of a dynamic adjustment mechanism in traditional bases. By setting up an opening and closing exhaust mechanism, and through the cooperation of a flip plate, a follower rack, a drive gear, and an exhaust fan, dynamic opening and closing and forced exhaust techniques are used to achieve the technical effect of coordinated control of heat dissipation and dust prevention, solving the problem of dust accumulation caused by existing passive heat dissipation and lack of active dust prevention.

The outer end of the drive worm 207 is connected and assembled with the output end of the worm drive motor 206 through a coupling. The worm drive motor 206 is mounted on one of the worm mounting seats 214.

[0022] Specifically, two first electric telescopic rods 101 are respectively installed on the inner walls of both sides of the upper surface of the supporting platform 100. The output end of the first electric telescopic rod 101 is connected and assembled to the bottom end of the lifting platform 300. Two vertical guide rails 104 are respectively provided on both sides of the upper surface of the supporting platform 100 to guide the lifting platform 300 during lifting.

The outer surface of the supporting platform 100 is provided with a movable handle 103 through the handle shaft 102, which is convenient for the operator to push and pull the whole equipment. At the top of the inner surface of the supporting platform 100 and at the position of each extension arm 202, an intercepting plate 105 is fixedly installed to block the extension arm 202 during the retraction period and prevent the extension arm 202 from colliding with the sun gear 208. The intercepting plate 105 has an arc-shaped structure and is made of rubber material.

[0023] A manufacturing process for an LED transparent display screen includes the following steps: Step 1: When adjusting the orientation of the LED transparent display module 700, rotate the reversing platform 400. The reversing platform 400 is rotatably connected to the lifting platform 300 through the second drive shaft 301. During the rotation, the reversing platform 400 drives the housing adapter 600, the display housing 800 and the internal LED transparent display module 700 to rotate synchronously for multi-angle adjustment. After the adjustment is completed, lock the second brake universal wheel 401 to fix the orientation of the LED transparent display module 700. Step 2: Start the worm drive motor 206 in the auxiliary mechanism to drive the worm 207 to rotate and drive the meshing drive worm wheel 205 to rotate. The drive worm wheel 205 rotates through the first drive shaft 210. The sun gear 208 meshes with the planetary gear 203 and pushes the extension arm 202 to unfold outward around the gear positioning shaft 204, so that the first brake caster 201 contacts the ground. At this time, the interceptor plate 105 prevents the extension arm 202 from excessively retracting and colliding with the sun gear 208. Step 3: When the internal temperature of the LED transparent display module 700 rises, the second electric telescopic rod 505 is activated, pushing the push-pull plate 504 to slide along the guide rail frame 503, driving the follower rack 506 to rise and fall. The follower rack 506 meshes with the drive gear 508, driving the crossbar 507 to rotate and opening the flip plate 502. The sealing strip 501 ensures the sealing of the joint. At this time, the exhaust fan 510 accelerates the discharge of hot air from the display casing 800 from the back opening. After the heat dissipation is completed, the second electric telescopic rod 505 is operated in reverse, and the flip plate 502 closes to prevent external dust from entering.

[0024] Based on the above, the present invention, by setting up an extension mechanism 200, a drive worm gear 205, a sun gear 208, and a first drive shaft 210, utilizes mechanical transmission and support extension techniques to achieve dynamic center of gravity adjustment and stable positioning, solving the problem of transport tilting caused by the lack of a dynamic adjustment mechanism in traditional bases. Specifically, the worm drive motor 206 drives the drive worm 207 to rotate, which in turn drives the first drive shaft 210 to rotate through meshing with the drive worm gear 205. The first drive shaft 210 rotates synchronously with the sun gear 208 via a flat key 211. The sun gear 208 meshes with multiple planetary gears 203, driving the extension arm 202 to extend outward around the gear positioning shaft 204, causing the first brake caster 201 to contact the ground, expanding the support area and lowering the overall center of gravity. Simultaneously, the lifting platform 300 adjusts its height via the first electric telescopic rod 101, and the reversing platform 400 adjusts its direction via the second drive shaft 301. The second brake caster 401 assists in support and steering. These three components work together to achieve multi-dimensional center of gravity adjustment, ensuring the mechanical balance of the large-size display module during transport or operation, and preventing damage due to inertia or... The invention addresses the issue of tilting and tipping caused by external forces. By implementing an opening and closing exhaust mechanism 500, and through the coordinated operation of a flip plate 502, a follower rack 506, a drive gear 508, and an exhaust fan 510, the invention achieves a synergistic control effect of heat dissipation and dust prevention using dynamic opening and closing and forced exhaust techniques. This solves the problem of dust accumulation caused by existing passive heat dissipation and lack of active dust prevention. Specifically, the second electric telescopic rod 505 pushes the push-pull plate 504 to slide along the guide rail frame 503, causing the follower rack 506 to rise and fall. The follower rack 506 and multiple drive gears... 508 engages, driving the crossbar 507 to drive the flip plate 502 to flip synchronously. When working, the flip plate 502 opens, and the exhaust fan 510 accelerates the discharge of hot air from the display screen housing 800 through the back opening, improving heat dissipation efficiency. When not working, the flip plate 502 closes, and the sealing strip 501 and the flip plate 502 enhance the sealing of the joint, preventing environmental dust from entering along the heat dissipation path, avoiding the accumulation of particulate matter on the circuit board or component pins, preventing oxidation or degradation of insulation performance, and meeting the requirements of efficient heat dissipation and active dust prevention, improving the adaptability to outdoor environments and operational reliability.

10. A manufacturing process for an LED transparent display screen, applied to an LED transparent display screen as described in any one of claims 1-8, characterized in that, Includes the following steps: Step 1: When adjusting the orientation of the LED transparent display module (700), rotate the reversing platform (400). The reversing platform (400) is rotatably connected to the lifting platform (300) through the second drive shaft (301). During the rotation, the reversing platform (400) drives the housing adapter (600), the display housing (800) and the internal LED transparent display module (700) to rotate synchronously for multi-angle adjustment. After the adjustment is completed, lock the second brake universal wheel (401) to fix the orientation of the LED transparent display module (700). Step 2: Start the worm drive motor (206) in the auxiliary mechanism to drive the worm (207) to rotate and drive the meshing drive worm wheel (205) to rotate. The worm wheel (208) is driven to rotate through the first drive shaft (210). The sun gear (208) meshes with the planetary gear (203) and pushes the extension arm (202) to unfold outward around the gear positioning shaft (204), so that the first brake caster (201) contacts the ground. At this time, the interceptor plate (105) prevents the extension arm (202) from excessively retracting and colliding with the sun gear (208). Step 3: When the internal temperature of the LED transparent display module (700) rises, the second electric telescopic rod (505) is activated, pushing the push-pull plate (504) to slide along the guide rail frame (503), driving the follower rack (506) to rise and fall. The follower rack (506) meshes with the drive gear (508), driving the crossbar (507) to rotate and opening the flip plate (502). The sealing strip (501) ensures the sealing of the connection. At this time, the exhaust fan (510) accelerates the discharge of hot air inside the display shell (800) from the back opening. After the heat dissipation is completed, the second electric telescopic rod (505) is operated in reverse, and the flip plate (502) closes to prevent external dust from entering.
