Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a spoiler that integrates intelligent driving functions. It is particularly suitable for vehicles equipped with advanced driver assistance systems or autonomous driving functions, and is used to integrate intelligent driving-related functional modules while achieving traditional aerodynamic optimization, thereby improving driving safety and system integration. Background Technology

[0002] With the rapid development of intelligent driving technology, modern cars need to be equipped with various sensors, such as cameras and radar, to achieve environmental perception. Currently, these sensors are usually independently mounted on the front bumper, grille, rearview mirrors, or windshield. This arrangement has several problems: First, exposed sensors are easily contaminated or damaged by external factors such as rain, mud, and collisions, affecting their performance and lifespan; second, independent mounting brackets may disrupt the aesthetics of the vehicle's overall appearance, appearing obtrusive; finally, at the rear, to perceive blind spots to the sides and rear, holes are usually drilled in the rear bumper or side panels to install sensors, resulting in insufficient field of view, complex manufacturing processes, and high costs. Furthermore, sensors and cameras are consumable parts; when a sensor or camera malfunctions and needs repair or replacement, it requires disassembling parts of the vehicle, which is time-consuming and labor-intensive. Car spoilers are common aerodynamic components at the rear of vehicles. Traditional vehicle spoilers mainly function as passive aerodynamic components, adjusting rear airflow to reduce the overall lift of the car at high speeds, thereby improving vehicle stability; their function is relatively simple.

[0003] Therefore, developing a technical solution that integrates intelligent driving function modules into the spoiler body to achieve real-time data interaction and collaborative control with the vehicle's intelligent driving system has become a key requirement for improving the overall performance of intelligent driving systems. Utility Model Content

[0004] The purpose of this invention is to overcome the defects in the existing technology and provide a spoiler that integrates intelligent driving functions. It can integrate intelligent driving function modules into the spoiler body to realize real-time data interaction and collaborative control with the vehicle's intelligent driving system.

[0005] To achieve the above objectives, the technical solution of this utility model is to design a spoiler integrating intelligent driving functions, including a spoiler body, which is installed above the rear of the vehicle. The spoiler body integrates an intelligent driving function module, a communication module, and a power module inside or on its surface. The communication module is used to transmit the data collected by the intelligent driving function module to the vehicle's intelligent driving system, or to receive control commands from the vehicle's intelligent driving system. The power module is used to supply power to the communication module and the intelligent driving function module.

[0006] The intelligent driving function module includes at least one of the following: An environmental sensing unit is used to collect environmental information behind the vehicle. Antenna unit, used to enhance vehicle communication, positioning and broadcast reception capabilities.

[0007] Specifically, the power module is a line interface connected to the vehicle's main power supply, preferably a 12V / 24V vehicle power supply.

[0008] Specifically, the communication module connects to the vehicle's intelligent driving system via the vehicle's existing CAN bus or Ethernet, transmitting data collected by the intelligent driving function module and receiving control commands.

[0009] Specifically, the environmental sensing unit includes at least one of the following: A camera is installed on the main body of the spoiler near the rear windshield to collect image information from behind the vehicle; the camera is preferably a wide-angle camera, and the camera's downward angle is preferably 3°~5°.

[0010] A millimeter-wave radar or ultrasonic radar is installed in the middle of the spoiler body, near the vehicle's centerline, to measure the distance and relative speed of obstacles behind the vehicle. The millimeter-wave radar has a detection range of ≥100 meters.

[0011] Specifically, the antenna element includes at least one of the following: 5G / 4G cellular antennas are used to upload vehicle status to the cloud or receive commands from the cloud; V2X antennas are used to interact with surrounding vehicles or streetlights; GNSS antennas are used to receive satellite signals; The broadcast antenna is used to receive FM / DAB signals.

[0012] Preferably, the antenna within the antenna unit is a flexible antenna. The flexible antenna is preferably attached to the inner side of the outer shell on top of the spoiler and fixed with acrylic pressure-sensitive adhesive or 3M adhesive. The integration of the flexible antenna not only retains the original intelligent driving system's communication and positioning capabilities but also further enhances the reliability and user experience of the intelligent driving system through lightweight design, environmental adaptability, and multi-band coordination.

[0013] Specifically, the spoiler body includes an outer shell and an internal frame, forming a cavity structure between the outer shell and the internal frame. The intelligent driving function module, communication module, and power module are placed within the cavity structure and are installed on the outer shell and internal frame by clips or bolts. The outer shell is preferably made of lightweight composite material, such as carbon fiber; the internal frame is preferably made of aluminum alloy profile or high-strength engineering plastic. Preferably, the cavity structure inside the spoiler has pre-reserved slots for the intelligent driving function module, communication module, and power module, allowing for modular design of each function module. This facilitates installation and maintenance while meeting the user's needs for different vehicle configurations.

[0014] Furthermore, an environmental sensing unit cavity is provided near the rear windshield of the outer casing. The environmental sensing unit is placed within this cavity. A slot is provided below the environmental sensing unit cavity, and a cover plate is provided at the slot. The cover plate is detachably mounted on the outer casing. A through hole is provided in front of the environmental sensing unit cavity, and the end of the environmental sensing unit is disposed within the through hole. The cover plate is detachably mounted on the outer casing by clips or bolts, allowing for easy removal and replacement of the environmental sensing unit if it is damaged. To ensure its airtightness, a sealing strip is provided at the contact point between the cover plate and the outer casing.

[0015] Furthermore, the outer casing is coated with a hydrophobic coating and has sealing strips along the edges for waterproofing and dustproofing. The hydrophobic coating reduces water droplet adhesion in high-speed airflow, preventing it from affecting sensor accuracy, while the sealing strips along the edges protect the internal modules from rain or mud erosion.

[0016] The advantages and beneficial effects of this utility model are as follows: 1. The intelligent driving function module is perfectly hidden inside the spoiler, avoiding the need for additional holes in other parts of the vehicle body for installation, thus maintaining the integrity and aesthetics of the vehicle body design.

[0017] 2. The spoiler provides a physical protective layer for the internal functional modules, effectively reducing direct damage from stone impacts, rainwater erosion, and soil cover, thus extending the sensor's service life.

[0018] 3. By placing sensors, especially side and rear radars and cameras, at the highest point of the rear of the vehicle, the field of vision is wider, the blind spots are smaller, and the perception performance of the intelligent driving system is improved.

[0019] 4. A cover is installed at the environmental sensing unit, which makes it easy to replace or disassemble the camera or radar, making maintenance more convenient. Attached Figure Description

[0022] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0023] according to Figures 1-3 As shown, this utility model is a spoiler integrating intelligent driving functions, including a spoiler body installed above the rear of a vehicle. The spoiler body integrates an intelligent driving function module, a communication module 4, and a power module 5 inside or on its surface. The communication module 4 transmits data collected by the intelligent driving function module to the vehicle's intelligent driving system or receives control commands from the vehicle's intelligent driving system. The power module 5 supplies power to the communication module and the intelligent driving function module. The intelligent driving function module includes at least one of the following: an environmental perception unit 6 for collecting environmental information behind the vehicle; and an antenna unit 7 for enhancing the vehicle's communication, positioning, and broadcast reception capabilities.

[0024] The power module 5 is a line interface that connects to the vehicle's main power supply.

[0025] The communication module 4 connects to the vehicle's intelligent driving system via the vehicle's existing CAN bus or Ethernet, transmitting data collected by the intelligent driving function module and receiving control commands.

[0026] The environmental perception unit 6 includes at least one of the following: a camera, installed on the spoiler body near the rear windshield, for collecting image information behind the vehicle; and a millimeter-wave radar or ultrasonic radar, installed in the middle of the spoiler body near the vehicle's centerline, for measuring the distance and relative speed of obstacles behind the vehicle.

[0027] The antenna unit 7 includes at least one of the following: a 5G / 4G cellular antenna for uploading vehicle status to the cloud or receiving instructions from the cloud; a V2X antenna for interacting with surrounding vehicles or streetlights; a GNSS antenna for receiving satellite signals; and a broadcast antenna for receiving FM / DAB signals.

[0028] The antenna in the antenna unit 7 is a flexible antenna.

[0029] The spoiler body includes an outer shell 1 and an inner frame 2. A cavity structure 3 is formed between the outer shell 1 and the inner frame 2. The intelligent driving function module, communication module 4, and power module 5 are placed in the cavity structure 3 and are installed on the outer shell 1 and the inner frame 2 by buckles or bolts.

[0030] An environmental sensing unit 6 cavity is provided near the rear windshield of the outer casing 1. The environmental sensing unit 6 is placed inside the environmental sensing unit 6 cavity. A slot is provided below the environmental sensing unit 6 cavity. A cover plate 61 is provided at the slot. The cover plate 61 is detachably installed on the outer casing 1. A through hole 62 is provided in front of the environmental sensing unit 6 cavity. The end of the environmental sensing unit 6 is disposed in the through hole 62.

[0031] The outer shell 1 is coated with a hydrophobic coating and has sealing strips 8 on its edges for waterproofing and dustproofing.

[0032] During the manufacturing process of the spoiler body, cavities for modules such as the intelligent driving function module, communication module 4, and power module 5 are pre-reserved, along with clip holes and screw holes for fixing the modules. Cable channels for signal and power transmission are also pre-installed for all modules, facilitating the later installation of the corresponding modules. During module installation, elastic material can be filled into the cavities of each module to provide cushioning and isolate vibration, thereby preventing poor contact, signal interruption, or damage caused by vehicle vibration.

[0033] The shape of the spoiler body depends on the overall appearance of the specific vehicle.

[0034] When the environmental perception unit 6 is a camera, if it is a single camera, it is preferably installed in the middle of the spoiler body. If it is two or three cameras, two cameras can be installed on the left and right sides of the spoiler body respectively, slightly tilted towards the side of the vehicle, to collect information on the blind spot behind the vehicle. The camera is preferably a wide-angle camera, and the camera's downward angle is preferably 3°~5°. When the environmental perception unit 6 is a millimeter-wave radar or ultrasonic radar, it is preferably installed in the middle of the spoiler body to measure the distance and relative speed of vehicles behind. The detection range of the millimeter-wave radar is ≥100 meters.

[0035] The environmental sensing unit 6 is generally a vulnerable component. For repair and replacement, simply use a tool to open the cover 61 of the slot below the cavity of the environmental sensing unit 6 in the housing 1, exposing the unit. Then, use the tool to remove the unit from its cavity and disconnect the cable clip at the end from the clip of the power module 5. For replacement, first engage the cable clip at the end with the clip of the power module 5. Then, use a tool to secure the environmental sensing unit 6 inside its cavity, placing the end of the unit within the through hole 62 in the housing 1. Adjust the angle of the unit, especially the camera's elevation angle, to match the initial elevation angle. If an error occurs, place shims in front of or behind the camera assembly to adjust the elevation angle. After adjustment, replace the cover 61 on the housing 1 and secure it.

[0036] When installing antenna unit 7, a 5G / 4G cellular antenna can be integrated at the top edge for uploading vehicle status to the cloud or receiving instructions from the cloud; a V2X antenna can be integrated at both sides for communicating with surrounding vehicles.

[0037] The communication module 4 connects to the vehicle's intelligent driving system via the vehicle's existing CAN bus or Ethernet, uploads perception data in real time, including the distance to the vehicle behind, relative speed, image feature points, etc., and receives relevant control signals issued by the vehicle's intelligent driving system.

[0038] Power module 5 is a vehicle-mounted 12V / 24V power supply line, which is connected through a branch of the rear bumper wiring harness.

[0039] like Figure 4 As shown, the overall workflow is as follows: The information collected and received by the environmental perception module 6 and antenna module 7 of the intelligent driving function module is transmitted to the vehicle's intelligent driving system through the communication module. The vehicle's intelligent driving system integrates and analyzes the received information to issue corresponding instructions. The power module 5 supplies power to the communication module 4 and the intelligent driving function module.

[0040] The bolts, nuts, screws, welding, and other related materials used in fixing and installing two or more parts described above are all known to those skilled in the art and will not be repeated here.

It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
