Description

Technical Field

[0001] This utility model relates to the field of sensor technology, specifically a hidden vehicle-mounted sensor. Background Technology

[0002] In the field of intelligent vehicles, onboard sensors are an essential component of advanced driver assistance systems. The integrated sensor system installed throughout the vehicle can collect comprehensive environmental data and monitor a range of safety risks during parking and driving.

[0003] Currently, in vehicles equipped with sensors, the sensors are typically placed on the roof. This not only provides a good field of view, reduces obstruction, and offers good detection performance, but also appropriately reduces maintenance costs. In existing technologies, sensors mounted on the front roof are mostly fixed in place, which not only affects the vehicle's streamlined design and increases wind resistance, but also easily detracts from the overall aesthetics. Therefore, how to improve onboard sensors to enhance vehicle streamlined design has become a pressing technical problem for those skilled in the art. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a hidden vehicle sensor, which mainly solves the problem that most existing vehicle sensors are fixed in place, which not only affects the smoothness of the vehicle body and increases wind resistance, but also easily damages the aesthetics of the whole vehicle.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a concealed vehicle-mounted sensor for installation on the roof of a vehicle. The roof has an entrance / exit with a cover plate at the entrance / exit. A sensor is mounted on the lower surface of the cover plate, and a lifting mechanism for driving the sensor to move up and down is provided at the lower end of the sensor. The lifting mechanism includes a baffle fixedly connected to the lower surface of the roof. The baffle is fixedly connected to one end of a slide rail. A slider is slidably connected to the slide rail. Two parallel connecting rods are rotatably connected to one side of the slider. The other ends of the two connecting rods are rotatably connected to a lifting platform, and the sensor is fixed to the lifting platform.

[0006] The aforementioned structural design incorporates a lifting mechanism (baffle, slide rail, slider, connecting rod, and lifting platform) that forms a parallel four-bar linkage lifting structure. This mechanism, when retracted, has a low height, allowing it to be cleverly positioned within the limited space between the roof trim panel and the vehicle body, without encroaching on passenger space. By installing the sensor under the cover and incorporating the lifting mechanism, the cover can be completely closed when the sensor is not in operation, maintaining a complete, smooth, and streamlined roof shape. This completely solves the problems mentioned in the background technology regarding "affecting the vehicle's smoothness, increasing wind resistance, and compromising the overall aesthetics," resulting in a more integrated and technologically advanced vehicle appearance, while also helping to reduce the drag coefficient and save energy. When needed, the lifting mechanism can smoothly raise the sensor beyond the roof. The roof remains the highest point of the vehicle, ensuring that once raised, the sensor has an unobstructed and optimal detection field of view, guaranteeing the accuracy and reliability of its detection data, perfectly balancing the dual requirements of "concealment" and "functionality."

[0007] Preferably, a support plate is fixedly connected to one end of the slide rail away from the baffle, and an electric push rod is mounted on the support plate. The output end of the electric push rod is connected to a push plate fixedly connected to the slider.

[0008] By adopting the above structural design, the electric push rod is installed on the fixed support plate and pushes the push plate connected to the slider, directly converting the linear thrust into the linear motion of the slider on the slide rail. The power transmission path is clear and efficient, and the structure is compact and reliable.

[0009] Preferably, a sealing ring is provided at the lower surface edge of the cover plate.

[0010] With the above structural design, a sealing ring is set on the lower surface edge of the cover plate. When the cover plate is closed, the sealing ring can tightly fit the edge of the opening in the roof, forming an effective seal. This prevents rainwater, car wash water, dust, mud, and other foreign objects from entering the vehicle through gaps or corroding the lifting mechanism and sensors themselves, greatly improving the durability, reliability, and service life of the entire system.

[0011] Preferably, the upper surface of the cover plate is flush with the roof surface, and the outer surface of the cover plate is coated with a coating that matches the color of the roof.

[0012] The above structural design ensures that the roof outline is completely continuous and has good overall integrity when the cover is closed; the use of a uniform color coating makes the cover visually blend into the surrounding roof.

[0013] Preferably, the upper end of the connecting rod near the baffle abuts against the baffle.

[0014] Compared with the prior art, the present invention has the following beneficial effects: By mounting the sensor under a cover and incorporating a lifting mechanism, the cover can be completely closed when the sensor is not in operation, maintaining a clean, smooth, and streamlined roofline. This completely solves the problems mentioned in the background technology, such as "affecting the vehicle's streamlined appearance, increasing wind resistance, and compromising the overall aesthetics," resulting in a more cohesive and technologically advanced vehicle appearance. It also helps reduce the drag coefficient and save energy. When needed, the lifting mechanism smoothly raises the sensor above the roof. The roof remains the highest point of the vehicle, ensuring that once raised, the sensor has an unobstructed and optimal detection field of view, guaranteeing the accuracy and reliability of its detection data. This perfectly balances the dual requirements of "concealment" and "functionality." Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3This utility model provides a concealed vehicle-mounted sensor for installation on the roof 9 of a vehicle. The roof 9 has an inlet / outlet that matches the shape of the sensor 12. An openable and closable cover 10 is provided at the inlet / outlet. The upper surface of the cover 10 is flush with the outer surface of the roof 9, and its outer surface is coated with a coating that perfectly matches the color and texture of the roof 9, thus achieving seamless visual concealment. To further improve sealing, an annular sealing ring 11 is fixedly embedded at the lower edge of the cover 10. When the cover 10 is closed, the sealing ring 11 tightly presses against the edge of the opening in the roof 9, effectively preventing rainwater and dust from entering. The lower surface of the cover 10 is fixedly connected to the sensor 12 via a mounting bracket. The lower end of the sensor 12 is equipped with a lifting mechanism that drives it and the cover plate 10 to move up and down together. The lifting mechanism includes a baffle 2 fixedly connected to the lower surface of the roof 9. The baffle 2 is fixedly connected to one end of the slide rail 1. A slider 6 is slidably connected to the slide rail 1. Two parallel connecting rods 8 are rotatably connected to one side of the slider 6 via a rotating shaft. The other ends of the two connecting rods 8 are also rotatably connected to the bottom of a lifting platform 5 via a rotating shaft. The sensor 12 is fixed on the lifting platform 5. The slide rail 1 is horizontally installed below the roof 9 and is fixed to the vehicle body structure by bolts or welding.

[0018] A support plate 3 is fixedly connected to one end of the slide rail 1 away from the baffle 2. An electric push rod 4 is mounted on the support plate 3. The output end of the electric push rod 4 faces the baffle 2 and is connected to a push plate 7 fixedly connected to the slider 6. Therefore, when the electric push rod 4 is activated, its output shaft can push or pull the slider 6, causing it to slide back and forth stably along the slide rail 1.

[0019] Working principle: When sensor 12 needs to operate, the vehicle controller sends a start command to electric push rod 4. The output shaft of electric push rod 4 extends, pushing slider 6 along slide rail 1 towards baffle 2. Because the upper end of connecting rod 8 near baffle 2 abuts against baffle 2, the upper end of connecting rod 8 is blocked by baffle 2 and cannot move, while the lower end of connecting rod 8 moves towards baffle 2, smoothly lifting lifting platform 5 upwards. Lifting platform 5 drives sensor 12 upwards, sensor 12 lifts cover plate 10, so that sensor 12 is fully extended outside the roof 9 and enters the optimal working position.

[0020] When sensor 12 finishes its operation, the controller retracts the output shaft of the electric push rod 4, pulling the slider 6 towards the support plate 3. Through the linkage of the connecting rod 8, the lifting platform 5 is smoothly pulled back, and sensor 12 descends and resets. The cover plate 10 closes under its own weight until the sealing ring 11 on its lower surface is tightly fitted with the roof 9, and sensor 12 is completely hidden and protected inside the vehicle body.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
