[0031] The following is for reference. Figure 1-Figure 3 Description of a front grille assembly 100 according to an embodiment of the present utility model.
[0032] like Figure 1 and Figure 2 As shown, the front grille assembly 100 according to an embodiment of the present invention includes a front grille 1 and a radar visor 2.
[0033] Specifically, such as Figure 1 and Figure 2 As shown, the front grille assembly 100 is used in a vehicle. The front grille 1 is provided with a window 11 and an airflow inlet 12. The airflow inlet 12 is located below the window 11 and is spaced apart. The radar 4 is adapted to be located behind the radar mask 2 and opposite to the radar mask 2. The radar mask 2 is located at the window 11.
[0034] Understandably, a radar 4 is installed at the front of the vehicle. For example, radar 4 can be a millimeter-wave radar. Radar 4 can detect and provide high-precision information on the relative distance and speed of objects in front, enabling the vehicle to achieve functions such as intelligent driving. Radar 4 is located behind radar cover 2. Radar cover 2 acts as a barrier to protect radar 4, preventing impurities such as mud, flying stones, or rain and snow from interfering with or damaging radar 4. This improves the stability and reliability of radar 4's detection and extends its service life.
[0035] The radar visor 2 is connected to the front grille 1 and is located at the window 11 of the front grille 1. Airflow inlets 12 are spaced apart below the window 11 and penetrate the front grille 1 in a front-to-back direction. During vehicle operation, at least part of the airflow passes through the airflow inlets 12 from front to back, causing a front-to-back airflow at the lower end of the radar visor 2. The flowing airflow can impact snow or sand and other impurities in front of the radar visor 2, thereby preventing the accumulation of snow or sand and other impurities in front of the radar visor 2.
[0036] This design protects radar 4 from obstructions such as snow in front of radar mask 2, preventing false alarms or detection failures. This reduces the safety risks associated with false alarms or malfunctions, thus improving driving safety. Furthermore, it enhances the stability and reliability of radar 4's detection capabilities, ensuring the stability of the vehicle's intelligent driving functions and improving the user's driving experience.
[0037] According to the front grille assembly 100 of this utility model embodiment, by providing a window 11 and an airflow inlet 12 on the front grille 1, and placing the radar mask 2 opposite to the radar 4 at the window 11, and making the airflow inlets 12 located below the window 11 and spaced apart, airflow in the front-rear direction can be generated at the lower end of the radar mask 2 when the vehicle is in motion, so as to avoid the accumulation of snow or sand and other impurities in front of the radar mask 2. This protects the radar 4 from the influence of impurities such as snow in front of the radar mask 2, avoids false alarms or detection failures of the radar 4, thereby reducing the safety risks caused by false alarms or failures of the radar 4 and improving driving safety. It also improves the stability and reliability of radar 4 detection, thereby ensuring the stability of the vehicle's intelligent driving functions and improving the user's driving experience.
[0038] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the portion of the front grille 1 located below the airflow inlet 12 forms a guide section 13, which is inclined forward from top to bottom. This allows impurities such as snow in front of the radar mask 2 to easily slide down the inclined surface of the guide section 13, preventing the accumulation of such impurities in front of the radar mask 2. Simultaneously, the upward inclination of the guide section 13 from front to back guides the airflow. During vehicle operation, the airflow flows into the airflow inlet 12 along the inclined surface of the guide section 13, increasing the airflow volume passing through the airflow inlet 12 and improving the intake efficiency. This enhances the impact force of the airflow, thereby improving the effect of impacting and breaking down snow and other impurities below the front of the radar mask 2.
[0039] This further protects radar 4 from obstructions such as snow in front of radar mask 2, preventing false alarms or detection failures. This reduces the safety risks associated with false alarms or malfunctions, improving driving safety. It also enhances the stability and reliability of radar 4's detection capabilities, ensuring the stability of the vehicle's intelligent driving functions and improving the user's driving experience.
[0040] In some embodiments of this utility model, such as Figure 1 and Figure 2As shown, the front grille assembly 100 also includes a front bumper 3, the upper end of which is connected to the lower end of the front grille 1. The upper surface of the front bumper 3 extends at least partially forward beyond the front grille 1 and is inclined forward in a top-to-bottom direction. The front bumper 3 protrudes forward, and its upper surface at least partially extends forward beyond the front grille 1, which helps the front bumper 3 to buffer impact forces when subjected to a collision, thereby improving the vehicle's collision protection performance and driving safety.
[0041] In this design, at least the portion of the upper surface of the front bumper 3 opposite to the airflow inlet 12 is tilted forward from top to bottom. This allows impurities such as snow in front of the radar shroud 2 to easily slide down the tilted upper surface of the front bumper 3, preventing the accumulation of such impurities in front of the radar shroud 2. Simultaneously, the upward tilt of the upper surface of the front bumper 3 from front to back guides airflow. During vehicle operation, airflow flows into the airflow inlet 12 along the tilted upper surface of the front bumper 3. This increases the airflow volume passing through the airflow inlet 12 and improves the intake efficiency, thereby increasing the impact force of the airflow and enhancing its effectiveness in impacting and breaking down snow and other impurities below the front of the radar shroud 2.
[0042] This further protects radar 4 from obstructions such as snow in front of radar mask 2, preventing false alarms or detection failures. This reduces the safety risks associated with false alarms or malfunctions, improving driving safety. It also enhances the stability and reliability of radar 4's detection capabilities, ensuring the stability of the vehicle's intelligent driving functions and improving the user's driving experience.
[0043] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the maximum dimension of the airflow inlet 12 in the left-right direction is greater than the dimension of the window 11 in the left-right direction. The radar radome 2 is located on the window 11 and the dimensions of the radar radome 2 are opposite to the dimensions of the window 11. In the left-right direction, the maximum dimension of the airflow inlet 12 is greater than the dimension of the radar radome 2, which can ensure that airflow can be generated at the lower end of the radar radome 2 in both the left and right directions. The flowing airflow can impact the snow or sand and other impurities in front of the radar radome 2, thereby avoiding the accumulation of snow or sand and other impurities in front of the radar radome 2 in both the left and right directions, and further reducing the risk of false alarms or detection failure of the radar 4.
[0044] In some embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 3As shown, the size of the airflow inlet 12 gradually increases from top to bottom along the left-right direction. This allows the airflow inlet 12 to be formed into a trapezoidal shape, avoiding right angles and thus enhancing the structural strength of the edge of the airflow inlet 12 and preventing stress concentration. Consequently, it prevents the front grille 1 from tearing and being damaged at the edge of the airflow inlet 12 due to vehicle bumps or airflow impact, thereby improving the structural stability of the front grille assembly 100.
[0045] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the two ends of the airflow inlet 12 in the left and right directions are flush with or extend beyond the two ends of the window 11 in the left and right directions. The radar radome 2 is located on the window 11 and the size of the radar radome 2 is opposite to the size of the window 11. In the left and right directions, the two ends of the airflow inlet 12 are flush with or extend beyond the two ends of the radar radome 2, which can ensure that airflow can be generated at the lower end of the radar radome 2 in both the left and right directions. The flowing airflow can impact the snow or sand and other impurities in front of the radar radome 2, thereby avoiding the accumulation of snow or sand and other impurities in front of the radar radome 2 in both the left and right directions, and further reducing the risk of false alarms or detection failure of the radar 4.
[0046] In some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the airflow inlet 12 has multiple corners 121, which are rounded. This can enhance the structural strength of the corners 121 at the edge of the airflow inlet 12 and avoid stress concentration. In turn, it can prevent the front grille 1 from tearing and being damaged at the edge of the airflow inlet 12 due to vehicle bumps or airflow impact, thereby improving the structural stability of the front grille assembly 100.
[0047] In some embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, the vertical dimension of the airflow inlet 12 is 'a', and it satisfies the condition: 5mm ≤ a ≤ 10mm. If a < 5mm, the vertical dimension of the airflow inlet 12 is too small, resulting in insufficient airflow through the inlet 12 from front to back, thus failing to guarantee the impact force of the airflow. If a > 10mm, the vertical dimension of the airflow inlet 12 is too large, leading to excessive airflow entering the inlet 12. This causes excessive rain, snow, sand, and other impurities to enter the area behind the radar diaphragm 2 along with the airflow, which in turn affects the radar 4.
[0048] This ensures that 5mm≤a≤10mm, which guarantees that the size of the airflow inlet 12 is appropriate in the vertical direction. This ensures that the impact force of the airflow is sufficient to prevent snow and other impurities from accumulating in front of the radar mask 2, and also prevents impurities from entering the rear of the radar mask 2 with the airflow. This ensures the stability and reliability of radar 4 detection.
[0049] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the lower end of the radar radome 2 has a rearward-extending flange 21. The width of the flange 21 in the front-rear direction is b, and it satisfies: 4mm ≤ b ≤ 10mm. The flange 21 can strengthen the structural strength of the radar radome 2 and reduce the risk of deformation caused by vehicle bumps. If b < 4mm, the structural strength of the flange 21 is too low; if b > 10mm, it is easy to interfere with or collide with the radar 4 behind the radar radome 2. Therefore, the width of the flange 21 in the front-rear direction is kept within the range of 4mm-10mm to ensure that the radar radome 2 has sufficient structural strength without interfering with the radar 4.
[0050] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the radar visor 2 is snap-fitted to the front grille 1 and / or connected via fasteners. This ensures the stability of the connection between the radar visor 2 and the front grille 1, thereby guaranteeing the structural stability of the front grille assembly 100. The snap-fit connection and / or fastener connection also allow for a detachable connection between the radar visor 2 and the front grille 1, facilitating subsequent disassembly and maintenance, and reducing later maintenance costs.
[0051] It should be noted that the thickness of the radar radome 2 is an integer multiple of half the wavelength of the radio wave emitted by the radar 4, such as the millimeter-wave radar 4. Therefore, when the radio wave emitted by the radar 4 passes through the radar radome 2, the peaks and troughs of the two radio waves reflected by the two surfaces in the thickness direction of the radar radome 2 can cancel each other out, thereby minimizing the loss of the radio wave penetrating the radar radome 2 and ensuring the detection performance of the radar 4.
[0052] The vehicle according to an embodiment of the present invention includes: the aforementioned front grille assembly 100.
[0053] According to the vehicle embodiment of this utility model, by setting a window 11 and an airflow inlet 12 on the front grille 1, and placing the radar mask 2 opposite to the radar 4 at the window 11, and making the airflow inlet 12 located below the window 11 and spaced apart, airflow in the front-rear direction can be generated at the lower end of the radar mask 2 when the vehicle is moving, so as to avoid the accumulation of snow or sand and other impurities in front of the radar mask 2. This can protect the radar 4 from the influence of impurities such as snow in front of the radar mask 2, avoid false alarms or detection failures of the radar 4, thereby reducing the safety risks caused by false alarms or failures of the radar 4 and improving driving safety. It can also improve the stability and reliability of radar 4 detection, thereby ensuring the stability of the vehicle's intelligent driving function and improving the user's driving experience.
