Description

Technical Field

[0001] This utility model relates to the field of signal light cover technology, and in particular to a signal light cover with a heat dissipation structure. Background Technology

[0002] Traffic lights are an indispensable and important facility in modern transportation systems. They scientifically direct vehicles and pedestrians to pass in an orderly manner through the regular changes of red, yellow and green lights. To ensure the normal use of traffic lights, it is necessary to protect all components with a traffic light cover.

[0003] Most signal light covers nowadays have relatively simple structures, often relying solely on heat dissipation slots to cool the internal electrical components. To prevent water from entering, these slots are mostly angled downwards. In cities with little rainfall, this passive cooling method has limited effectiveness, and after prolonged use, a large amount of dust accumulates at the slot openings. This dust may affect the normal heat dissipation of the slots, further impacting the light cover's cooling performance.

[0004] Therefore, given the relatively simple heat dissipation structure of existing signal light covers and its limited heat dissipation effect, a signal light cover with a heat dissipation structure can be designed. Through flexible opening and closing and active heat dissipation, the heat dissipation range of the cover can be expanded in rainless weather. Since the ambient temperature is already low during rain, the heat dissipation grooves are used to passively dissipate heat from the signal light during rainfall, thereby enhancing the heat dissipation effect of the cover and effectively preventing the signal light from overheating and being damaged. Utility Model Content

[0005] In order to overcome the problem that most signal light covers only rely on heat dissipation slots to cool the internal electrical components, which is a passive heat dissipation method with limited effectiveness in cities with little rainfall, and that a large amount of dust accumulates at the slot openings after long-term use, which may affect the normal heat dissipation of the heat dissipation slots, this utility model is proposed.

[0006] The technical solution of this utility model is as follows: a signal light cover with a heat dissipation structure, including a cover body and an electric telescopic rod for controlling the extension and retraction of an L-shaped top cover. Two sets of electric telescopic rods are symmetrically arranged. The electric telescopic rods are located at the top of the inner side of the cover body. One side of the L-shaped top cover is connected to the outer telescopic end of the electric telescopic rod. The top of the cover body is closed by the L-shaped top cover. Multiple sets of fans with a 45° inclined distribution are equidistantly arranged on the inner side of the cover body. The fans are located below the L-shaped top cover that closes the cover body, forming an optimized airflow channel.

[0007] Preferably, the internal components of the signal light are protected by a lamp cover body. The extension and retraction of the electric telescopic rod can be flexibly controlled according to weather conditions. When it rains, the electric telescopic rod extends to push the L-shaped top cover to close the lamp cover body. When it is not raining, the electric telescopic rod retracts to pull the L-shaped top cover up, leaving the rear of the lamp cover body partially open. At this time, the fan runs to accelerate the airflow inside the lamp cover body. Thus, through the synergistic effect of the flexible opening and closing of the L-shaped top cover and the forced air cooling of the fan, efficient heat dissipation and protection of the signal light are achieved. This expands the heat dissipation range of the lamp cover in rainless weather, enhances the heat dissipation effect of the lamp cover, and effectively prevents the signal light from overheating and being damaged.

[0008] Preferably, a humidity sensor is installed at the top of the lampshade body. The humidity sensor senses changes in the weather. In rainy weather, the humidity sensor sends an extension command to the electric telescopic rod to control the L-shaped top cover to close the lampshade body.

[0009] Preferably, a storage groove is provided on the inner side of the top wall of the lampshade body, the L-shaped top cover slides along the storage groove, the outer edge of the top of the L-shaped top cover protrudes, and the bottom of the side plate of the L-shaped top cover is provided with a groove that fits into the rear baffle of the lampshade body.

[0010] Preferably, a fixing frame is provided on the inner side of the lampshade body, the fixing frame is set at a 45° angle, and the fan is rotatably connected to the fixing frame.

[0011] Preferably, a miniature drive motor is provided at the rear end of the fixed frame. The output end of the miniature drive motor is connected to the drive shaft of the fan. The miniature drive motor is electrically connected to the electric telescopic rod. When the electric telescopic rod retracts, the miniature drive motor is controlled to run. When the electric telescopic rod extends, the miniature drive motor is controlled to shut down.

[0012] Preferably, multiple sets of first heat dissipation grooves are equidistantly provided at the bottom of the lampshade body, and multiple sets of second heat dissipation grooves are equidistantly provided on the left and right sides and the rear end of the lampshade body, with the second heat dissipation grooves being inclined downwards at 45°.

[0013] The beneficial effects of this utility model are:

[0014] When using traffic lights, the internal components are protected by the lamp cover. The electric telescopic rod can be flexibly extended and retracted according to weather conditions. When it rains, the electric telescopic rod extends to push the L-shaped top cover to close the lamp cover. When it is not raining, the electric telescopic rod retracts, causing the L-shaped top cover to close, leaving the rear of the lamp cover partially open. At this time, the fan runs to accelerate the airflow inside the lamp cover. Through the flexible opening and closing of the L-shaped top cover and the forced air cooling of the fan, efficient heat dissipation and protection of the traffic light are achieved. This solves the problem that most traffic light lamp covers often only rely on heat dissipation slots to cool the internal electrical components. In cities with little rainfall, this passive heat dissipation method has limited effectiveness, and after long-term use, a large amount of dust will accumulate at the slot, which may affect the normal heat dissipation of the heat dissipation slots. This enhances the heat dissipation effect of the lamp cover and effectively prevents the traffic light from overheating and being damaged. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figure 1 and Figure 3 This utility model provides an embodiment: a signal light cover with a heat dissipation structure, including a cover body 1 and an electric telescopic rod 3 for controlling the extension and retraction of an L-shaped top cover 2. Two sets of electric telescopic rods 3 are symmetrically arranged. The electric telescopic rods 3 are located at the top of the inner side of the cover body 1. One side of the L-shaped top cover 2 is connected to the outer telescopic end of the electric telescopic rod 3. The top of the cover body 1 is closed by the L-shaped top cover 2. Multiple sets of fans 4 are equidistantly arranged at 45° angles on the inner side of the cover body 1. The fans 4 are located below the cover body 1 closed by the L-shaped top cover 2. The operation of the fans 4 accelerates the airflow inside the cover body 1, forming an optimized airflow channel.

[0024] Please see Figure 2 In this embodiment, a humidity sensor 101 is provided at the top of the lampshade body 1. The humidity sensor 101 senses weather changes. When it rains, the humidity sensor 101 sends an extension command to the electric telescopic rod 3 to control the L-shaped top cover 2 to close the lampshade body 1, thereby realizing flexible control of closing the lampshade body 1 according to the weather conditions and flexibly adjusting the heat dissipation intensity of the lampshade body 1.

[0025] Please see Figure 4 and Figure 6 In this embodiment, a storage groove 201 is provided on the inner side of the top wall of the lampshade body 1. The L-shaped top cover 2 slides along the storage groove 201. The outer edge of the top of the L-shaped top cover 2 protrudes. The bottom of the side plate of the L-shaped top cover 2 is provided with a groove 202 that fits into the rear baffle of the lampshade body 1. The storage groove 201 defines the extension path of the L-shaped top cover 2. When the L-shaped top cover 2 is removed, the groove 202 at the front end of the L-shaped top cover 2 fits into the groove 202 at the corresponding position of the lampshade body 1, ensuring that the L-shaped top cover 2 closes the lampshade body 1.

[0026] Please see Figure 5 and Figure 6 In this embodiment, a fixing frame 401 is provided on the inner side of the lampshade body 1. The fixing frame 401 is inclined at 45°. The fan 4 is rotatably connected to the fixing frame 401. A micro drive motor 402 is provided at the rear end of the fixing frame 401. The output end of the micro drive motor 402 is connected to the drive shaft of the fan 4. The micro drive motor 402 is electrically connected to the electric telescopic rod 3. When the electric telescopic rod 3 retracts, the micro drive motor 402 is controlled to run. When the electric telescopic rod 3 extends, the micro drive motor 402 is controlled to close. The fan 4 is placed stably at an upward tilt of 45° by the fixing frame 401. The micro drive motor 402 drives the fan 4 to rotate. The rotating fan 4 sends air to the half-open opening at the rear end of the lampshade body 1, thereby forming an optimized airflow channel and ensuring that the heat dissipation capacity of the lampshade body 1 is further enhanced in rainless weather.

[0027] Multiple sets of first heat dissipation grooves 102 are equidistantly provided at the bottom end of the lampshade body 1, and multiple sets of second heat dissipation grooves 103 are equidistantly provided on the left and right sides and the rear end of the lampshade body 1. The second heat dissipation grooves 103 are inclined downward at 45°. The first heat dissipation grooves 102 dissipate heat from the bottom of the lampshade body 1. The second heat dissipation grooves 103 ensure the ventilation effect of each side of the lampshade body 1. At the same time, the inclined design of the second heat dissipation grooves 103 can prevent rainwater from entering the lampshade body 1.

[0028] When there is no rain, the electric telescopic rod 3 retracts and drives the L-shaped top cover 2 into the storage slot 201. At this time, the rear end of the lampshade body 1 is in a half-open state. At the same time, the micro drive motor 402 controls the fan 4 on the fixing frame 401 to rotate. The rotating fan 4 sends air to the half-open opening at the rear end of the lampshade body 1, thereby forming an optimized airflow channel and accelerating the heat dissipation of the lampshade body 1.

[0029] When it rains, the humidity sensor 101 detects that the humidity has increased to a set value and sends an extension command to the electric telescopic rod 3. The extension of the electric telescopic rod 3 pushes the L-shaped top cover 2 out of the storage slot 201. The removal of the L-shaped top cover 2 causes the groove 202 at the front end of the L-shaped top cover 2 to fit into the corresponding groove 202 of the lampshade body 1, so that the L-shaped top cover 2 closes the lampshade body 1. At the same time as the electric telescopic rod 3 extends, the micro drive motor 402 turns off and controls the fan 4 to stop rotating. The first heat dissipation slot 102 and the second heat dissipation slot 103 ensure air circulation inside and outside the lampshade body 1 and ensure heat dissipation of the lampshade body 1.

[0030] Through the above steps, the internal components of the signal light are protected by the lamp cover body 1. The electric telescopic rod 3 can be flexibly extended and retracted according to the weather conditions. When it rains, the electric telescopic rod 3 extends to push the L-shaped top cover 2 to close the lamp cover body 1. When it is not raining, the electric telescopic rod 3 retracts to drive the L-shaped top cover 2 to retract, so that the rear of the lamp cover body 1 is half open. At this time, the fan 4 runs to accelerate the air flow inside the lamp cover body 1. Thus, through the synergistic effect of the flexible opening and closing of the L-shaped top cover 2 and the forced air cooling of the fan 4, the signal light achieves efficient heat dissipation and protection, thereby expanding the heat dissipation range of the lamp cover and enhancing its heat dissipation capacity in rainless weather.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
