[0002] Gas station eaves signs refer to functional signage facilities installed on the edge or top of gas station canopies. They are mainly used to convey safety warnings, service information, or brand image, and are primarily in the form of lightbox signs.

[0003] To improve heat dissipation efficiency, current gas station signage eaves light boxes generally use ventilation holes for ventilation and heat dissipation. Although this structure can dissipate heat, it is easy for dust and moisture to enter, shortening its service life.

[0004] In view of this, a gas station sign eaves light box is designed to solve the above problems. Summary of the Invention

[0005] To address the problems mentioned in the background section, this invention provides a gas station sign eaves light box, which features extended service life and improved safety.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a gas station sign eaves light box, comprising a mounting frame, a rectangular connecting frame, a U-shaped connecting frame, a U-shaped frame, and a sign, arranged sequentially from near to far from the eaves of the gas station. The rectangular connecting frame is fixedly connected to the mounting frame, and the U-shaped connecting frame is fixedly connected to and communicates with the rectangular connecting frame. A lighting mechanism is installed inside the connection position between the U-shaped connecting frame and the rectangular connecting frame. A main heat dissipation mechanism is installed between the lighting mechanism and the U-shaped connecting frame and the rectangular connecting frame. The U-shaped frame is fixedly connected to the U-shaped connecting frame. An auxiliary heat dissipation mechanism is installed inside the U-shaped frame. A moving drive mechanism and a rotating drive mechanism are respectively installed between the auxiliary heat dissipation mechanism and the U-shaped connecting frame. A flipping drive mechanism is installed between the sign and the U-shaped connecting frame and the U-shaped frame.

[0007] Furthermore, the lighting mechanism includes a circular hollow aluminum frame disposed inside the connection position between the U-shaped connecting frame and the rectangular connecting frame. The outer wall of the circular hollow aluminum frame is provided with a plurality of embedded grooves at equal intervals along the circumference, and a lamp plate is fixedly connected inside the embedded grooves.

[0008] Furthermore, the main heat dissipation mechanism includes a ventilation and heat dissipation pipe disposed inside the connection position between the U-shaped connecting frame and the rectangular connecting frame. The two ends of the ventilation and heat dissipation pipe extend through the U-shaped connecting frame and the rectangular connecting frame to the outside and are fixedly connected to the through section. A circular hollow aluminum frame is fixedly sleeved on the outside of the ventilation and heat dissipation pipe. Several rings of heat dissipation holes are equally spaced on the ventilation and heat dissipation pipe in the area inside the circular hollow aluminum frame. The ventilation and heat dissipation pipe communicates with the inside of the circular hollow aluminum frame through the several rings of heat dissipation holes.

[0009] Furthermore, the auxiliary heat dissipation mechanism includes a heat dissipation frame located inside the U-shaped frame below the circular hollow aluminum frame. The heat dissipation frame has several mounting slots at equal intervals, and a heat dissipation fan is fixedly connected inside the mounting slot.

[0010] Furthermore, the moving drive mechanism includes two first cylinders symmetrically fixed to the U-shaped connecting frame near the side wall of the rectangular connecting frame and located below the rectangular connecting frame. The output ends of the two first cylinders extend through the U-shaped connecting frame and are fixed to the inside of the U-shaped frame. The two support frames are located on both sides of the heat sink frame. The two support frames are connected to the connecting shaft through bearings. One end of the connecting shaft is fixed to the heat sink frame.

[0011] Furthermore, the rotation drive mechanism includes two gears fixedly sleeved on two connecting shafts away from each other's end walls, and two racks symmetrically fixed on the side wall of the return-shaped connecting frame near the return-shaped frame. The two racks are located above the two racks and are meshed. The area inside the return-shaped frame above and below the heat sink can be used to rotate the heat sink. The gears disengage from the racks and rotate 180°.

[0012] Furthermore, the flipping drive mechanism includes two second cylinders symmetrically fixed to the rectangular connecting frame near the side wall of the rectangular connecting frame and located below the rectangular connecting frame, and two sliding grooves symmetrically opened on the side wall of the rectangular connecting frame away from the rectangular connecting frame. The two second cylinders are located outside the two first cylinders. The output ends of the two second cylinders respectively penetrate the rectangular connecting frame and extend into the interior of the rectangular connecting frame, where a movable seat is fixedly connected.

Obviously, the described embodiments are only some embodiments of the present invention, and 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.

[0017] This invention provides the following technical solution: a gas station sign eaves light box, comprising a mounting frame 1, a rectangular connecting frame 2, a U-shaped connecting frame 3, a U-shaped frame 4, and a sign 5 arranged sequentially from near to far from the eaves of the gas station. The rectangular connecting frame 2 is fixedly connected to the mounting frame 1, the U-shaped connecting frame 3 is fixedly connected to and communicates with the rectangular connecting frame 2, a lighting mechanism is installed inside the connection position between the U-shaped connecting frame 3 and the rectangular connecting frame 2, a main heat dissipation mechanism is installed between the lighting mechanism and the U-shaped connecting frame 3 and the rectangular connecting frame 2, the U-shaped frame 4 is fixedly connected to the U-shaped connecting frame 3, an auxiliary heat dissipation mechanism is installed inside the U-shaped frame 4, a moving drive mechanism and a rotating drive mechanism are respectively installed between the auxiliary heat dissipation mechanism and the U-shaped connecting frame 3, and a flipping drive mechanism is installed between the sign 5 and the U-shaped connecting frame 3 and the U-shaped frame 4.

[0018] See appendix Figure 1-7 Before using the eaves light box for the gas station sign, fix the mounting bracket 1 to the eaves of the gas station with screws to complete the installation; During use, the eaves light box of the gas station sign is cooled by the main heat dissipation mechanism. If the temperature is too high, it is cooled by both the main heat dissipation mechanism and the auxiliary heat dissipation mechanism. During the use of the gas station sign eaves light box, by activating the flipping drive mechanism, the sign 5 is flipped to the lowest point. At this time, the sign 5 is located below the auxiliary heat dissipation mechanism. Then, the moving drive mechanism is activated, which drives the auxiliary heat dissipation mechanism to move closer to the sign 5. During the movement, it cooperates with the rotation drive mechanism to complete the rotation, turning the auxiliary heat dissipation mechanism into a dust blowing mechanism. The moving drive mechanism continues to drive the dust blowing mechanism to move, and the moving dust blowing mechanism removes dust from the surface of the sign 5. After dust removal, reverse drive reset can be performed.

[0019] Specifically, the lighting mechanism includes a circular hollow aluminum frame 101 located inside the connection position between the U-shaped connecting frame 3 and the rectangular connecting frame 2. The outer wall of the circular hollow aluminum frame 101 has several recessed grooves at equal intervals along the circumference, and a lamp plate 102 is fixed inside the recessed grooves.

[0020] See appendix Figure 4 The lighting mechanism is powered by a number of lamp panels 102 on a circular hollow aluminum frame 101. The lamp panels 102 are electrically connected to the power supply system and control system of the gas station, and are powered by the power supply system and controlled by the control system.

[0021] Specifically, the main heat dissipation mechanism includes a ventilation and heat dissipation pipe 201 located inside the connection position between the U-shaped connecting frame 3 and the rectangular connecting frame 2. The two ends of the ventilation and heat dissipation pipe 201 extend through the U-shaped connecting frame 3 and the rectangular connecting frame 2 to the outside and are fixedly connected to the through section. A circular hollow aluminum frame 101 is fixedly sleeved on the outside of the ventilation and heat dissipation pipe 201. Several rings of heat dissipation holes 202 are equally spaced on the ventilation and heat dissipation pipe 201 in the internal area of ​​the circular hollow aluminum frame 101. The ventilation and heat dissipation pipe 201 communicates with the inside of the circular hollow aluminum frame 101 through the several rings of heat dissipation holes 202.

[0022] See appendix Figure 5 The main heat dissipation mechanism is ventilated by ventilation pipes 201. The flowing air carries away the heat conducted by several lamp panels 102 to the circular hollow aluminum frame 101, thus achieving heat dissipation. At the same time, it does not come into contact with the interior, preventing dust from entering and giving it dust-free properties.

[0023] Specifically, the auxiliary heat dissipation mechanism includes a heat dissipation frame 301 located inside the U-shaped frame 4 below the circular hollow aluminum frame 101. The heat dissipation frame 301 has several mounting slots at equal intervals, and a heat dissipation fan 302 is fixedly connected inside the mounting slot.

[0024] See appendix Figure 2 and 3The auxiliary heat dissipation mechanism uses several cooling fans 302 to assist in heat dissipation, accelerate airflow, and make hot air evenly contact the circular hollow aluminum frame 101, avoiding local high temperature and accelerating the heat dissipation rate. The cooling fans 302 are electrically connected to the power supply system and control system of the gas station, and are powered by the power supply system and controlled by the control system.

[0025] Specifically, the moving drive mechanism includes two first cylinders 401 symmetrically fixed to the side wall of the U-shaped connecting frame 3 near the rectangular connecting frame 2 and located below the rectangular connecting frame 2. The output ends of the two first cylinders 401 extend through the U-shaped connecting frame 3 and into the U-shaped frame 4, where they are fixed to support frames 403. The two support frames 403 are located on both sides of the heat sink 301. The two support frames 403 are connected to a connecting shaft 402 through a bearing. One end of the connecting shaft 402 is fixed to the heat sink 301.

[0026] See appendix Figure 2 , 3 6. The moving drive mechanism activates two first cylinders 401, which extend their output ends. The output ends of the two first cylinders 401 drive the two support frames 403 to move. The two support frames 403 drive the heat sink 301 to move via two connecting shafts 402, thus realizing the moving drive of the heat sink 301. The two first cylinders 401 are electrically connected to the power supply system and control system of the gas station, and are powered by the power supply system and controlled by the control system.

[0027] Specifically, the rotation drive mechanism includes two gears 501 fixedly sleeved on two connecting shafts 402 away from each other's end walls, and two racks 502 symmetrically fixed on the side wall of the return-shaped connecting frame 3 near the return-shaped frame 4. The two racks 502 are located above the two racks 502 and are meshed. The area inside the return-shaped frame 4 located above and below the heat sink 301 allows the heat sink 301 to be rotated. The gears 501 disengage from the racks 502 and rotate 180°.

[0028] See appendix Figure 2-3 The rotation drive mechanism drives two gears 501 to move through two movable connecting shafts 402. During the movement of the two gears 501, they rotate due to their meshing with the two racks 502. The two gears 501 drive the two connecting shafts 402 to rotate, and the two connecting shafts 402 drive the heat sink 301 to rotate, thus realizing the rotation drive of the heat sink 301.

[0029] Specifically, the flipping drive mechanism includes two second cylinders 601 symmetrically fixed to the side wall of the rectangular connecting frame 3 near the rectangular connecting frame 2 and located below the rectangular connecting frame 2, and two sliding grooves 603 symmetrically opened on the side wall of the rectangular connecting frame 4 away from the rectangular connecting frame 3. The two second cylinders 601 are located outside the two first cylinders 401. The output ends of the two second cylinders 601 respectively penetrate through the rectangular connecting frame 3 and extend into the interior of the rectangular connecting frame 4, where a movable seat 602 is fixed. Sliding rods 605 are fixed inside the two sliding grooves 603 respectively. Sliding seats 604 are movably sleeved on the two sliding rods 605 respectively. The two movable seats 602 and the two sliding seats 604 are hinged to the signboard 5.

[0030] See appendix Figure 2 , 3 4 and 7, the flipping drive mechanism activates two second cylinders 601, the output ends of the two second cylinders 601 extend, and the output ends of the two second cylinders 601 drive two moving seats 602 to move closer to the sign 5. During the movement of the two moving seats 602, the sign 5 rotates along the two moving seats 602 and the two sliding seats 604, and slides down in the direction away from the return frame 4 until the set drive time is reached and it stops. At this time, the sign 5 drops to the lowest point. Similarly, the reverse drive resets, realizing the flipping drive of the sign 5.

[0031] Working principle of the invention: Before using the eaves light box for the gas station sign, fix the mounting bracket 1 to the eaves of the gas station with screws to complete the installation. During the use of the eaves light box of the gas station sign, ventilation is provided by the ventilation and heat dissipation pipe 201. The flowing air carries away the heat conducted by several light panels 102 to the circular hollow aluminum frame 101, thus achieving heat dissipation. If the temperature is too high, several cooling fans 302 are used for auxiliary heat dissipation to accelerate air flow and make the hot air evenly contact the circular hollow aluminum frame 101, avoiding local high temperature and accelerating the heat dissipation rate. During operation, the eaves light box of the gas station sign is activated by two second cylinders 601. The output ends of these two cylinders extend, driving two movable seats 602 to move closer to the sign 5. As the movable seats 602 move, the sign 5 rotates along the two movable seats 602 and the two sliding seats 604, moving away from the rotating frame 4 while simultaneously sliding down until the set driving time is reached and it stops. At this point, the sign 5 descends to its lowest point, positioned below several cooling fans 302. Two first cylinders 401 are activated, and their output ends are extended. The output ends of the two first cylinders 401 drive the two support frames 403 to move. The two support frames 403 drive the heat sink 301 to move through the two connecting shafts 402. At the same time, the two moving connecting shafts 402 drive the two gears 501 to move. During the movement of the two gears 501, they rotate due to their meshing with the two racks 502. The two gears 501 drive the two connecting shafts 402 to rotate, and the two connecting shafts 402 drive the heat sink 301 to rotate until the two gears 501 disengage from the two racks 502. The heat sink 301 rotates 180° and contacts the top of the signboard 5. The several cooling fans 302 become several dust blowing fans. The two first cylinders 401 continue to drive. Since the signboard 5 is not in a vertical state, the bottom of the heat sink 301 rotates through the two connecting shafts 402 and always contacts the signboard 5, changing the vertical dust blowing of the several dust blowing fans to inclined dust blowing, thus removing dust from the surface of the signboard 5. After dust removal, reverse drive reset can be performed.
