Description

Technical Field

[0001] This invention relates to a heat dissipation structure for an electronic information display housing and its usage method, belonging to the field of electronic information display technology. Background Technology

[0002] In modern life, electronic information displays refer to information display devices that use electronic technology to transform imperceptible signals into perceptible signals. They have advantages such as small footprint, flexible and variable display formats, and the ability to simultaneously display multiple types of information. They are gradually replacing electromechanical instruments and other display forms to become the most important display method. However, existing electronic information displays generate heat after prolonged use. The heat dissipation effect inside the display casing directly affects the lifespan of the display. Traditional electronic information displays generally do not have corresponding heat dissipation structures inside the casing, but simply rely on ventilation holes for heat dissipation, resulting in poor heat dissipation and thus seriously affecting the lifespan of the electronic information display. Moreover, existing fan cooling structures can mostly only continuously dissipate heat to a single part and cannot provide comprehensive heat dissipation for the electronic information display, resulting in poor heat dissipation. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a heat dissipation structure for an electronic information display housing and its usage method.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: A heat dissipation structure for an electronic information display housing includes a housing and display panels located on both sides of the housing. The housing is provided with a heat dissipation mechanism for dissipating heat from the two sets of display panels. The heat dissipation mechanism is connected to the housing via a moving mechanism. The heat dissipation mechanism includes a cylinder, a dual-axis motor is installed inside the cylinder, one end of the dual-axis motor extends to the outside of the cylinder and is provided with fan blades, a protective cover is installed on the fan blades, and a frame is movably fitted on the outer wall of the cylinder, the frame being movably connected to the cylinder through two sets of symmetrically arranged movable shafts.

[0005] Preferably, the moving mechanism includes a U-shaped seat movably fitted onto the frame, with two symmetrical movable shafts movably connected to the frame at both ends inside the U-shaped seat, a sliding plate at the top of the U-shaped seat, a rotating shaft rotatably connected to the top of the sliding plate, and a turntable at the top of the rotating shaft.

[0006] Preferably, the turntable has a rotatably connected connecting rod at the top eccentric position, the other end of the connecting rod has a toothed plate, one side of the toothed plate has a gear meshing with it, and the top of the slide plate has a guide sleeve for guiding the reciprocating motion of the toothed plate.

[0007] Preferably, the first gear is movably connected to the slide plate via a fixed shaft, the top of the fixed shaft is provided with a second gear, and a third gear is provided on one side of the second gear to mesh with it.

[0008] Preferably, the gear three is movably connected to the slide plate via a fixed shaft two, and a slider connected to the slide plate is movably sleeved on the fixed shaft two.

[0009] Preferably, the fixed shaft two is provided with gear four at the top of the slider, and a sliding sleeve is provided on one side of the cover to slide in connection with the slide plate and the slider.

[0010] Preferably, the sliding sleeve has a groove that matches the fourth gear, and a rack that matches the fourth gear is provided on one side of the groove.

[0011] Preferably, the bottom end of the rotating shaft extends to the top of the cylinder and is movably connected to a horizontally arranged universal joint. The other end of the universal joint is movably connected to a shaft extending into the cylinder. The bottom end of the shaft is provided with a fifth gear, and a sixth gear meshing with the fifth gear is provided on one side of the fifth gear.

[0012] Preferably, gear six is ​​movably connected to the cylinder via a connecting shaft, and gear seven is provided on the connecting shaft and below gear six. One side of gear seven is meshed with gear eight, which is connected to the other output shaft of the dual-shaft motor.

[0013] According to another aspect of the present invention, a method of using a heat dissipation structure for an electronic information display housing includes the following steps; S1: Start the dual-axis motor. Its first output shaft drives the fan blades to rotate and generate heat dissipation airflow, which is guided by the protective cover 6 and blown toward the display panels on both sides. S2: The second output shaft of the dual-axis motor drives gear eight to rotate, which in turn meshes with gear seven, gear six, and gear five to rotate. Power is transmitted to the rotating shaft through the shaft and universal joint, causing the rotating shaft to drive the turntable to rotate synchronously. S3: When the turntable rotates, the connecting rod with eccentric connection pulls the toothed plate to make reciprocating linear motion along the guide sleeve. The toothed plate meshes with and drives gear one, gear two, and gear three to rotate in sequence, thereby driving fixed shaft two and gear four to rotate. S4: Gear four meshes with the rack inside the sliding sleeve, driving the slider, slide plate and U-shaped seat to slide back and forth along the sliding sleeve, synchronously driving the heat dissipation mechanism to move as a whole, expanding the heat dissipation coverage area; S5: During the movement of the heat dissipation mechanism, the frame 7 is hinged to the cylinder through the movable shaft one, and the U-shaped seat is hinged to the frame through the movable shaft two. This structure adaptively adjusts the tilt angle of the cylinder and the fan blades, so that the heat dissipation airflow fits the surface of the display panel.

[0014] The beneficial effects of this invention are: The fan blades are driven to rotate by a dual-axis motor to generate cooling airflow. This airflow, combined with a moving mechanism, drives the cooling mechanism to move back and forth along the sliding sleeve. The angle of the cylinder can also be adjusted to achieve uniform heat dissipation for the display panels on both sides and the interior of the casing. The heat dissipation efficiency is significantly improved compared to the traditional fixed structure.

[0015] By leveraging the linkage design of gears eight, seven, six, five, universal joints, and shafts, the single power source of the dual-axis motor is transformed into a composite action of rotational heat dissipation, reciprocating movement, and angle adjustment of the heat dissipation mechanism. No additional drive components are required, resulting in a compact structure and reduced energy consumption.

[0016] The frame is movably connected to the cylinder via a movable shaft one, and the U-shaped seat is movably connected to the frame via a movable shaft two, allowing for flexible adjustment of the fan blade's heat dissipation angle to adapt to the heat dissipation requirements of different display panels; a protective cover is provided on the outside of the fan blade to effectively prevent foreign objects from being drawn in and improve safety during use.

[0017] The entire heat dissipation process is automated through a dual-axis motor-driven gear transmission and linkage mechanism, eliminating the need for manual adjustment and reducing operational complexity. Furthermore, the smooth and reliable movement is ensured by the guiding and limiting of components such as guide sleeves, sliders, and sliding sleeves. Attached Figure Description

[0026] Please see Figure 1-7 A method of using a heat dissipation structure for an electronic information display housing includes the following steps; S1: Start the dual-axis motor 4. Its first output shaft drives the fan blades 5 to rotate and generate heat dissipation airflow, which is guided by the protective cover 6 and blown toward the display panels on both sides. S2: The second output shaft of the dual-axis motor 4 drives gear 8 31 to rotate, which in turn meshes with and drives gear 7 30, gear 6 29, and gear 5 28 to rotate. Power is transmitted to the rotating shaft 11 through shaft 27 and universal joint 26, so that the rotating shaft 11 drives the turntable 12 to rotate synchronously. S3: When the turntable 12 rotates, the connecting rod 13 with the eccentric connection pulls the toothed plate 14 to make reciprocating linear motion along the guide sleeve. The toothed plate 14 meshes with the drive gear 15, gear 27, and gear 318 to rotate in sequence, thereby driving the fixed shaft 219 and gear 42 to rotate. S4: Gear 22 meshes with rack 25 inside sliding sleeve 23, driving slider 20, slide plate 21 and U-shaped seat 9 to slide back and forth along sliding sleeve 23, synchronously driving the heat dissipation mechanism to move as a whole, expanding the heat dissipation coverage area; S5: During the movement of the heat dissipation mechanism, the frame 7 is hinged to the cylinder 3 via the movable shaft 1 8, and the U-shaped seat 9 is hinged to the frame 7 via the movable shaft 2 10. This adaptively adjusts the tilt angle of the cylinder 3 and the fan blade 5, so that the heat dissipation airflow fits the surface of the display panel 2.

[0027] When in use, the power is started and the cooling airflow is generated: the dual-axis motor 4 is started, and one of its output shafts directly drives the fan blades 5 to rotate, generating a cooling airflow pointing towards the display panel 2. The protective cover 6 protects the fan blades 5; the other output shaft of the dual-axis motor 4 drives the gear 8 31 to rotate.

[0028] Gear 8 31 meshes with and drives gear 7 30 to rotate. Gear 7 30 drives gear 6 29 to rotate through the connecting shaft. Gear 6 29 meshes with and drives gear 5 28. Gear 5 28 drives shaft 27 to rotate. Shaft 27 transmits power to rotating shaft 11 through universal joint 26, realizing synchronous rotation of rotating shaft 11.

[0029] The rotating shaft 11 drives the top turntable 12 to rotate. The connecting rod 13 at the eccentric part of the turntable 12 pulls the toothed plate 14 to reciprocate linearly along the guide sleeve. The toothed plate 14 meshes with the drive gear 15 to rotate. The gear 15 drives the gear 2 17 to rotate through the fixed shaft 16. The gear 2 17 meshes with the drive gear 3 18. The gear 3 18 drives the gear 4 22 to rotate through the fixed shaft 2 19. The gear 4 22 meshes with the rack 25 in the groove 24 of the sliding sleeve 23, driving the slider 20 to slide along the sliding sleeve 23. This, in turn, drives the slide plate 21, U-shaped seat 9, frame 7 and cylinder 3 to reciprocate along the sliding sleeve 23, expanding the heat dissipation range.

[0030] The frame 7 is movably connected to the cylinder 3 via the first movable shaft 8, and the U-shaped seat 9 is movably connected to the frame 7 via the second movable shaft 10. During the reciprocating movement of the heat dissipation mechanism, the tilt angle of the cylinder 3 can be adaptively adjusted through the torque feedback of the gear transmission to ensure that the heat dissipation airflow of the fan blade 5 always adheres to the surface of the display panel 2, thereby achieving precise heat dissipation.
