Technical Field

[0001] This utility model belongs to the technical field of rain sensor cover, and in particular relates to a rain sensor cover with a heat dissipation and dustproof structure. Background Technology

[0002] A rain sensor cover with a heat dissipation and dust protection structure combines the two functions of heat dissipation and dust protection, ensuring the normal operation of the rain sensor under various environmental conditions. This design will effectively improve the stability and service life of the rain sensor, especially its performance under extreme weather conditions.

[0003] According to a published specification (Publication No.: CN 209727129 U), a sensor with a dustproof structure includes a bottom cover, a first heat-conducting insulating plate is provided on the inner side of the bottom cover, an inner bottom frame is provided on the top of the first heat-conducting insulating plate, the inner bottom frame and the first heat-conducting insulating plate are an integral structure, a first shock-absorbing rubber pad is provided on the inner side of the inner bottom frame, and the sensor body is provided on the top of the first shock-absorbing rubber pad.

[0004] In the aforementioned application, the cooperation between components such as the bottom outer cover and the first heat-conducting isolation plate makes it difficult to solve the problem of the protective cover being adjustable to cover or uncover the sensor according to actual needs, resulting in the inability to effectively prevent damage to the sensor from the external environment, which needs to be improved. Utility Model Content

[0005] The purpose of this utility model is to provide a rain sensor cover with a heat dissipation and dustproof structure. By cooperating with the gears, electric telescopic rods and other components inside the adjustable component, the problem of not being able to make the protective cover adjustable to cover or uncover the sensor according to actual needs is solved.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a rain sensor cover with a heat dissipation and dustproof structure, comprising a sensor, a support rod fixedly connected to the surface of the sensor, an adjustable component on the top of the sensor, the adjustable component including a rotating rod, one end of the rotating rod passing through the side of the support rod, a protective cover fixedly connected to the circumference of the rotating rod, a gear fixedly connected to one end of the rotating rod, a crossbar fixedly connected to the side of the support rod, a housing fixedly connected to one end of the crossbar, a rack slidably connected to the inner wall of the housing, an electric telescopic rod fixedly connected to one end of the rack, and the rack and the gear meshing with each other.

[0008] Furthermore, a groove is provided on the inner wall of the outer casing, and a limiting rod is slidably connected to the inner wall of the groove. The end of the limiting rod away from the groove is fixedly connected to the side of the rack. The design of the limiting rod and the groove helps to limit the movement trajectory of the rack.

[0009] Furthermore, the sensor is located on the displacement trajectory of the protective cover, the protective cover has ventilation slots on its side, and the electric telescopic rod is located on the inner wall of the outer shell. This design helps to cover the sensor when the protective cover moves.

[0010] Furthermore, there are two support rods, which are symmetrical to each other along the vertical central axis of the rotating rod. Several ventilation slots are provided, which facilitates ventilation of the protective cover.

[0011] Furthermore, a heat dissipation assembly is provided on the side of the support rod. The heat dissipation assembly includes an L-shaped rod, one end of which is fixedly connected to the side of the support rod. A rotating shaft is rotatably connected to one end of the L-shaped rod. Blades are fixedly connected to the circumferential surface of the rotating shaft. A connecting rod is fixedly connected to the circumferential surface of the rotating shaft. An extrusion rod is fixedly connected to the inner wall of the protective cover. The rotation of the blades generates airflow to dissipate heat from the sensor.

[0012] Furthermore, the connecting rod is located on the displacement trajectory of the extrusion rod, the blade is located on the side of the sensor, and several blades are arranged in a circumferential array on the circumferential surface of the rotating shaft. This design is beneficial to directly extruding the connecting rod when the extrusion rod moves.

[0013] Furthermore, a torsion spring is fixedly connected to the circumferential surface of the rotating shaft, and the end of the torsion spring away from the rotating shaft is fixedly connected to one end of the L-shaped rod. The design of the torsion spring is beneficial to the automatic reset of the rotating shaft when it is not driven.

[0014] This utility model has the following beneficial effects:

[0015] This invention achieves adjustable protective cover by cooperating with gears, electric telescopic rods, and other components within the adjustable assembly. This allows the protective cover to be adjusted to cover or uncover the sensor as needed, reducing the time the sensor is exposed to the outside environment. This effectively prevents damage to the sensor from the external environment, not only improving the sensor's protective performance and extending its service life, but also ensuring its working stability and accuracy under various environmental conditions.

[0016] This invention utilizes the interplay between components such as blades and extrusion rods within the heat dissipation assembly. The rotation of the blades generates airflow, which is then directly directed onto the sensor. This helps reduce the sensor's temperature, preventing performance degradation or damage due to overheating. The heat dissipation function significantly extends the sensor's lifespan. Through the movement mechanism of the protective cover (such as rotation that drives the extrusion rod and blades), automated protection and heat dissipation functions are achieved, reducing the need for manual intervention and improving the system's autonomy and reliability.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 This utility model is a rain sensor cover with a heat dissipation and dustproof structure, including a sensor 1. A support rod 2 is fixedly connected to the surface of the sensor 1. An adjustable component 3 is provided on the top of the sensor 1. The adjustable component 3 includes a rotating rod 31. One end of the rotating rod 31 passes through the side of the support rod 2. A protective cover 37 is fixedly connected to the circumference of the rotating rod 31. A gear 36 is fixedly connected to one end of the rotating rod 31. A crossbar 32 is fixedly connected to the side of the support rod 2. A housing 33 is fixedly connected to one end of the crossbar 32. A rack 35 is slidably connected to the inner wall of the housing 33. An electric telescopic rod 34 is fixedly connected to one end of the rack 35. The rack 35 and the gear 36 mesh with each other.

[0028] A groove 39 is provided on the inner wall of the outer casing 33. A limit rod 310 is slidably connected to the inner wall of the groove 39. The end of the limit rod 310 away from the groove 39 is fixedly connected to the side of the rack 35. The design of the limit rod 310 and the groove 39 is beneficial to restricting the movement trajectory of the rack 35.

[0029] Sensor 1 is located on the displacement trajectory of protective cover 37. Ventilation slots 38 are provided on the side of protective cover 37, and electric telescopic rod 34 is located on the inner wall of housing 33. This design is beneficial to cover sensor 1 when protective cover 37 moves.

[0030] There are two support rods 2, which are symmetrical to each other along the vertical central axis of the rotating rod 31. Several ventilation slots 38 are provided, which facilitates ventilation of the protective cover 37.

[0031] A heat dissipation assembly 4 is provided on the side of the support rod 2. The heat dissipation assembly 4 includes an L-shaped rod 41. One end of the L-shaped rod 41 is fixedly connected to the side of the support rod 2. A rotating shaft 42 is rotatably connected to one end of the L-shaped rod 41. A blade 43 is fixedly connected to the circumferential surface of the rotating shaft 42. A connecting rod 44 is fixedly connected to the circumferential surface of the rotating shaft 42. A pressing rod 45 is fixedly connected to the inner wall of the protective cover 37. The rotation of the blade 43 generates airflow to dissipate heat from the sensor 1.

[0032] The connecting rod 44 is located on the displacement trajectory of the extrusion rod 45, and the blade 43 is located on the side of the sensor 1. Several blades 43 are provided and are arranged in a circumferential array on the circumferential surface of the rotating shaft 42. This design is beneficial to directly extruding the connecting rod 44 when the extrusion rod 45 moves.

[0033] A torsion spring 46 is fixedly connected to the circumferential surface of the rotating shaft 42. The end of the torsion spring 46 away from the rotating shaft 42 is fixedly connected to one end of the L-shaped rod 41. The design of the torsion spring 46 is conducive to the automatic reset of the rotating shaft 42 when it is not driven.

[0034] A specific application of this embodiment is as follows: The protective cover 37 is located on top of the sensor 1, and the sensor 1 is located on the movement trajectory of the protective cover 37. The protective cover 37 is used to protect the sensor 1. By activating the electric telescopic rod 34, when the telescopic end of the electric telescopic rod 34 extends, it drives the rack 35 to move, pushing the rack 35 to the side closer to the sensor 1. The rack 35 and the gear 36 mesh with each other. When the rack 35 moves to the side closer to the sensor 1, it drives the gear 36 to rotate counterclockwise. The counterclockwise rotation of the gear 36 drives the rotating rod 31 and the protective cover 37 to rotate counterclockwise, causing the protective cover 37 to rotate away from the sensor 1, so that the protective cover 37 is removed from the top of the sensor 1, exposing the protective cover 37. When it is necessary to continue to cover the sensor 1, the electric telescopic rod 34 is activated. When the telescopic end of the electric telescopic rod 34 retracts to the side away from the sensor 1, it drives the rack 35 to move away from the sensor 1. When the rack 35 moves in this way, it drives the gear 36 to rotate clockwise. Rotating the lever 36 clockwise will cause the rotating rod 31 to rotate clockwise, which in turn will cause the protective cover 37 to rotate clockwise. This clockwise rotation of the protective cover 37 will cause it to rotate onto the sensor 1, covering the top of the sensor 1 and reducing its exposure to the outside environment. The protective cover 37 is adjustable, allowing it to cover or uncover the sensor 1 as needed, minimizing its exposure time and effectively preventing damage from external environmental factors such as dust, rain, and sunlight. When protection is needed, the protective cover 37 can cover the sensor 1, reducing the impact of high temperatures or external heat sources. When heat dissipation is required, the protective cover 37 can be automatically removed, allowing for better heat dissipation and preventing overheating from affecting the sensor 1's performance. This not only improves the sensor 1's protection performance and extends its lifespan but also ensures its stability and accuracy under various environmental conditions.

[0035] As the protective cover 37 rotates closer to the sensor 1, it drives the pressing rod 45 to move closer to the sensor 1. The connecting rod 44 is located on the movement trajectory of the pressing rod 45. When the pressing rod 45 moves, it presses the connecting rod 44 from top to bottom, causing the connecting rod 44 to move downwards. The downward movement of the connecting rod 44 drives the rotating shaft 42 and the blades 43 to rotate. The rotation of the blades 43 generates a certain amount of wind. The blades 43 are located on the side of the sensor 1, and the wind generated by the rotation of the blades 43 blows directly onto the sensor 1. When the protective cover 37 covers the sensor 1 for protection, it blows air to cool the sensor 1. The rotation of the blade 43 generates wind, which blows the air directly onto the sensor 1, helping to reduce the temperature of the sensor 1 and avoid performance degradation or damage due to overheating. Especially in outdoor environments, the rain sensor 1 may be exposed to sunlight or high temperatures. The heat dissipation function can significantly extend the service life of the sensor 1. Through the movement mechanism of the protective cover 37 (such as the rotation driving the squeeze rod 45 and the blade 43 to rotate), the protection and heat dissipation functions are automated, reducing the need for manual intervention and improving the autonomy and reliability of the system.
