Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, specifically to an in-vehicle radar assembly and an automobile. Background Technology

[0002] Most automotive driver assistance systems use cameras (such as image recognition technology) in conjunction with radar (such as millimeter-wave radar or lidar) to monitor the external environment.

[0003] Ordinary millimeter-wave radar waves or lidar lasers generally cannot penetrate metal. Therefore, existing vehicle radars are typically positioned in front of or below metal protective devices such as body crash beams. This leaves the area in front of the radar mostly covered by plastic components like bumper skins and trim, offering insufficient protection. In low-speed collisions, radars, being precision electronic components, are highly susceptible to damage, such as housing cracks or connector breakage. To ensure sealing, radar systems are generally constructed as a single welded unit, making it impossible to replace individual components; the entire assembly must be replaced, resulting in high repair costs. Summary of the Invention

[0004] (i) The technical problem to be solved by the present invention is that existing vehicle radars are generally arranged in front of or below metal protective devices such as vehicle body anti-collision beams. When a vehicle is involved in a low-speed collision, the radar is easily damaged to a certain extent and the entire assembly must be replaced, resulting in high maintenance costs.

[0005] (II) Technical Solution To address the aforementioned technical problems, embodiments of the present invention provide a vehicle-mounted radar assembly for automobiles, comprising a radar unit, a protective mechanism, and a tilting mechanism; The protective mechanism forms a protective zone, the radar unit is installed in the protective zone, and the protective mechanism can open or close the protective zone; One end of the flipping mechanism is connected to the anti-collision beam of the vehicle, and the other end is connected to the protective mechanism via a transmission. The flipping mechanism can drive the protective mechanism to flip to the side of the anti-collision beam facing the vehicle body.

[0006] Furthermore, the protective mechanism includes an upper guard, a lower guard plate, a mounting seat, and a transmission assembly; The ends of the upper protective cover and the lower protective plate are respectively hinged to the upper and lower ends of the mounting seat on the same side, and the radar unit is mounted on the lower protective plate; The transmission assembly is mounted on the mounting seat and is connected to the upper guard and the lower guard plate respectively. The transmission assembly drives the upper guard and the lower guard plate to rotate synchronously so as to move closer to or away from the mounting seat. The upper protective cover, the lower protective plate, and the mounting seat together form the protective area.

[0007] Furthermore, the transmission assembly includes an actuator motor, an upper drive gear, and a lower drive gear; The actuator is fixed in the mounting seat, and the output end of the actuator is connected to the upper drive gear or the lower drive gear. The upper drive gear and the lower drive gear are meshed together. The upper guard is hinged to the mounting seat via a first pivot, and the lower guard plate is hinged to the mounting seat via a second pivot. A first driven gear is sleeved at the position corresponding to the upper drive gear on the first rotating shaft, and the first driven gear is meshed with the upper drive gear. A second driven gear is sleeved at the position corresponding to the lower drive gear on the second rotating shaft, and the second driven gear is meshed with the lower drive gear.

[0008] Furthermore, the flipping mechanism includes a base and a flipping assembly; One end of the base is fixedly connected to the anti-collision beam, and the other end of the base is hinged to the top of the mounting seat; The base is also provided with a flipping component, which can drive the mounting seat to flip around the hinge point between the mounting seat and the base.

[0009] Furthermore, the flipping assembly includes a rotating rod, a flipping motor, a drive gear, and a flipping gear; The base and the mounting seat are rotatably connected by the rotating rod, and the rotating gear is sleeved on the outer side of the rotating rod. The rotating gear rotates synchronously with the rotating rod. The base is equipped with the flip motor, the output end of which is connected to the drive gear, and the drive gear meshes with the flip gear.

[0010] Furthermore, the base includes a first connecting ear, and the mounting seat includes a second connecting ear; At least two of the first connecting ears are spaced apart at the bottom of the base, and at least two of the second connecting ears are spaced apart at the top of the mounting seat; The first connecting ear has a mounting hole, and the flip motor is installed in the mounting hole; The first connecting ear is also provided with a first rotating hole, and the second connecting ear is provided with a second rotating hole at the position corresponding to the first rotating hole. The rotating rod passes through the corresponding first rotating hole and second rotating hole in sequence.

[0011] Furthermore, the radar unit includes a front shroud, a rear shroud, a rotary motor, and a radar assembly; The rear cover forms a receiving cavity with an opening at one end, and the front cover covers the opening to close the receiving cavity; The cavity contains the rotary motor and the radar assembly. The output of the rotary motor is connected to the radar assembly. The rotary motor drives the radar assembly to rotate along the direction of the front shield cross-section.

[0012] Furthermore, the radar assembly includes a support frame and a radar; The bracket is rotatably connected to the inner bottom wall of the rear cover, the radar is mounted on the side of the bracket facing the front cover, and the output end of the rotary motor is connected to the bracket for transmission.

[0013] Furthermore, the support includes vertically arranged horizontal and vertical plates; The horizontal plate is located on the inner bottom wall of the rear cover. The horizontal plate has a rotating hole. One end of the rotating shaft passes through the rotating hole and is connected to the rear cover. The other end of the rotating shaft is connected to the output end of the rotary motor. The radar is mounted on the side of the vertical plate facing the front shroud.

[0014] Embodiments of the present invention also provide a vehicle including the above-described vehicle radar assembly.

[0015] The beneficial effects of this invention are: This invention provides a vehicle-mounted radar assembly. A protective mechanism forms a protected area, within which a radar unit is installed. The protective mechanism can open or close the protected area. Under normal operating conditions, the protective mechanism is open, exposing the radar unit for normal scanning and detection. When the vehicle detects an impending collision, the protective mechanism closes, enclosing the radar unit within the protected area, forming a physical protective barrier. One end of a tilting mechanism is connected to the vehicle's crash beam, and the other end is driven to the protective mechanism. The tilting mechanism can tilt the protective mechanism to the side of the crash beam facing the vehicle body, i.e., directly behind the crash beam. When the protective mechanism is closed, the tilting mechanism tilts the entire protective mechanism, along with the internal radar unit, backward, transferring it from in front of or below the crash beam to behind it, using the crash beam as an additional physical barrier for secondary protection of the radar unit. This configuration achieves omnidirectional scanning of the radar unit during normal operation and active protection during collision hazards. The protective mechanism's closing and the flipping mechanism's flipping work together, meaning that while the protective mechanism closes, the flipping mechanism flips, transferring the radar unit to a safe area before a collision occurs. This allows the vehicle-mounted radar assembly to be positioned as far outward as possible, requiring only two sets to be placed at the front and rear of the vehicle to complete the scanning process. In low-speed collisions, only low-cost components such as the protective mechanism need to be replaced, while the core module of the radar unit does not need to be replaced, significantly reducing maintenance costs.

[0016] The present invention provides a vehicle including the aforementioned radar assembly. By integrating the vehicle-mounted radar assembly into the vehicle, the vehicle not only has a wide-range radar scanning and detection capability, but also has an active radar protection capability in the event of a collision, effectively solving the technical problems of radar vulnerability and high maintenance costs in traditional radar deployment schemes.

Detailed Implementation

[0020] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] In the description of this invention, it should be noted that the terms "upper" and "lower," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0023] Example 1 like Figures 1 to 9 As shown, the present invention provides an in-vehicle radar assembly for automobiles, including a radar unit 100, a protective mechanism 200 and a tilting mechanism 300. The protective mechanism 200 forms a protected area, the radar unit 100 is installed in the protected area, and the protective mechanism 200 can open or close the protected area. One end of the flipping mechanism 300 is connected to the anti-collision beam 400 of the car, and the other end is connected to the protective mechanism 200. The flipping mechanism 300 can drive the protective mechanism 200 to flip to the side of the anti-collision beam 400 facing the car body.

[0024] In this embodiment, the protective mechanism 200 forms a protective zone, and the radar unit 100 is installed within the protective zone. The protective mechanism 200 can open or close the protective zone. Under normal operating conditions, the protective mechanism 200 is in the open state, and the radar unit 100 is exposed to the outside, enabling normal scanning and detection. When the vehicle detects an impending collision, the protective mechanism 200 closes, enclosing the radar unit 100 within the protective zone, forming a physical protective barrier.

[0025] One end of the tilting mechanism 300 is connected to the vehicle's anti-collision beam 400, and the other end is connected to the protective mechanism 200 via a transmission connection. The tilting mechanism 300 can tilt the protective mechanism 200 to the side of the anti-collision beam 400 facing the vehicle body, that is, to the side directly behind the anti-collision beam 400. When the protective mechanism 200 is closed, the tilting mechanism 300 tilts the entire protective mechanism 200 along with the internal radar unit 100 backward, transferring it from the front or below the anti-collision beam 400 to the rear of the anti-collision beam 400, using the anti-collision beam 400 as an additional physical barrier to provide secondary protection for the radar unit 100.

[0026] This embodiment enables the radar unit 100 to perform omnidirectional scanning during normal operation and active protection in the event of a collision hazard. The synergistic effect of the closing of the protective mechanism 200 and the flipping of the flipping mechanism 300—that is, while the protective mechanism 200 closes, the flipping mechanism 300 flips, transferring the radar unit 100 to a safe area before a collision—allows the vehicle-mounted radar assembly to be positioned as far outward as possible. Only two sets are needed, one at the front and one at the rear of the vehicle, to complete the scanning operation. In low-speed collisions, only low-cost components such as the protective mechanism 200 need to be replaced; the core module of the radar unit 100 does not need to be replaced, significantly reducing maintenance costs.

[0027] According to one embodiment provided by the present invention, such as Figure 1 , Figure 2 , Figure 4 and Figure 8 As shown, the protective mechanism 200 includes an upper guard 201, a lower guard plate 202, a mounting seat 203, and a transmission assembly; The ends of the upper protective cover 201 and the lower protective plate 202 are respectively hinged to the upper and lower ends of the mounting seat 203 on the same side, and the radar unit 100 is mounted on the lower protective plate 202. The transmission assembly is mounted on the mounting seat 203. The transmission assembly is connected to the upper guard 201 and the lower guard plate 202 respectively. The transmission assembly drives the upper guard 201 and the lower guard plate 202 to rotate synchronously so as to move closer to or away from the mounting seat 203. The upper protective cover 201, the lower protective plate 202, and the mounting seat 203 together form a protective zone.

[0028] In this embodiment, the ends of the upper cover 201 and the lower cover 202 are respectively hinged to the upper and lower ends of the mounting base 203 on the same side. That is, the end of the upper cover 201 is hinged to the top of the mounting base 203, and the end of the lower cover 202 is hinged to the bottom of the mounting base 203. Both the upper cover 201 and the lower cover 202 can rotate relative to the mounting base 203 around their respective hinge axes to open and close. The radar unit 100 is mounted on the lower cover 202. When the lower cover 202 is flipped open, the radar unit 100 flips outward with the lower cover 202 to obtain a good scanning field of view.

[0029] Furthermore, a transmission assembly is mounted on the mounting base 203, and the transmission assembly is connected to the upper shield 201 and the lower shield 202 respectively. Specifically, the transmission assembly can drive the upper shield 201 and the lower shield 202 to rotate synchronously, causing them to move closer to or further away from the mounting base 203. Under normal operating conditions, the transmission assembly drives the upper shield 201 to rotate upward and the lower shield 202 to rotate downward, exposing the radar unit 100. In a collision hazard situation, the transmission assembly reverses its direction, causing the upper shield 201 to rotate downward and the lower shield 202 to rotate upward, bringing them closer together and eventually closing.

[0030] The upper protective cover 201, lower protective plate 202, and mounting base 203 together form a protective zone. When both the upper protective cover 201 and lower protective plate 202 are in the closed position, the three together form a relatively enclosed space, within which the radar unit 100 is completely enclosed. Both the upper protective cover 201 and lower protective plate 202 are made of high-strength materials (such as high-strength hot-formed steel plates), possessing high impact resistance and effectively protecting the internal radar unit 100 from external impacts in the event of a collision, providing switchable physical protection for the radar unit 100.

[0031] According to one embodiment provided by the present invention, such as Figure 1 , Figure 2 , Figure 4 and Figure 8 As shown, the transmission assembly includes an actuator motor 204, an upper drive gear 205, and a lower drive gear 206; The actuator 204 is fixed in the mounting seat 203. The output end of the actuator 204 is connected to the upper drive gear 205 or the lower drive gear 206. The upper drive gear 205 and the lower drive gear 206 are meshed together. The upper guard 201 is hinged to the mounting base 203 via a first pivot, and the lower guard plate 202 is hinged to the mounting base 203 via a second pivot. A first driven gear is fitted at the position corresponding to the upper drive gear 205 on the first rotating shaft, and the first driven gear is meshed with the upper drive gear 205. A second driven gear is fitted at the position corresponding to the lower drive gear 206 on the second rotating shaft, and the second driven gear is meshed with the lower drive gear 206.

[0032] In this embodiment, the actuator 204 is fixedly mounted inside the mounting base 203 as a power source. The actuator 204 can be a stepper motor or a servo motor, providing precise angle control. The output end of the actuator 204 is connected to one of the upper drive gear 205 or the lower drive gear 206. The upper drive gear 205 and the lower drive gear 206 are meshed together, and when the actuator 204 drives one of the gears to rotate, the other gear rotates synchronously in the opposite direction.

[0033] Correspondingly, the upper guard 201 is hinged to the mounting base 203 via a first pivot, and the lower guard plate 202 is hinged to the mounting base 203 via a second pivot. A first driven gear is fitted onto the first pivot at the position corresponding to the upper drive gear 205, and the first driven gear meshes with the upper drive gear 205. A second driven gear is fitted onto the second pivot at the position corresponding to the lower drive gear 206, and the second driven gear meshes with the lower drive gear 206. The first pivot rotates synchronously with the first driven gear, and the second pivot rotates synchronously with the second driven gear.

[0034] When the actuator motor 204 starts, its output drives the upper drive gear 205 (or the lower drive gear 206) to rotate. The upper drive gear 205 drives the first driven gear to rotate through meshing, and the first driven gear drives the first rotating shaft and the upper protective cover 201 fixedly connected to it to rotate. At the same time, the upper drive gear 205 drives the lower drive gear 206 to rotate in the opposite direction through meshing, and the lower drive gear 206 drives the second driven gear to rotate through meshing, and the second driven gear drives the second rotating shaft and the lower protective plate 202 fixedly connected to it to rotate in the opposite direction. Through the above gear transmission structure, the upper protective cover 201 and the lower protective plate 202 achieve synchronous and opposite flipping motion.

[0035] The actuator motor 204 can be precisely controlled by the vehicle's control system to rotate at an angle that allows for precise opening and closing of the upper guard 201 and the lower guard plate 202. Gear transmission offers advantages such as precise transmission ratio, good motion synchronization, and high load-bearing capacity, enabling it to operate reliably for extended periods in vehicle environments.

[0036] According to one embodiment provided by the present invention, such as Figure 1 , Figure 2 , Figure 5 , Figure 7 , Figure 8 and Figure 9As shown, the flipping mechanism 300 includes a base 301 and a flipping assembly; One end of the base 301 is fixedly connected to the anti-collision beam 400, and the other end of the base 301 is hinged to the top of the mounting seat 203; The base 301 is also equipped with a flipping component, which can drive the mounting back seat 203 to flip around the hinge point between the mounting back seat 203 and the base 301.

[0037] In this embodiment, one end of the base 301 is fixedly connected to the anti-collision beam 400 (which can be the front or rear anti-collision beam of the vehicle), providing a stable mounting base for the tilting mechanism 300. The base 301 can be fixed to the anti-collision beam 400 by bolts or welding to ensure that the base 301 will not shift or fall off in the event of a vehicle collision. The other end of the base 301 is hinged to the top of the mounting rear seat 203, allowing the mounting rear seat 203 to rotate relative to the base 301 about the hinge point.

[0038] Furthermore, a flipping assembly is also provided on the base 301, which can drive the mounting back seat 203 to flip around the hinge point between the mounting back seat 203 and the base 301. The flipping assembly is the power source and transmission component of the flipping mechanism 300, which drives the mounting back seat 203 to rotate from the normal working position to the protective position.

[0039] Under normal operating conditions, the mounting seat 203, its protective mechanism 200, and radar unit 100 are positioned in front of or below the anti-collision beam 400, and the radar unit 100 can scan normally. When a collision hazard is detected, the flipping assembly is activated, driving the mounting seat 203 to rotate rearward around the hinge point, flipping the entire protective mechanism 200 (including the internal radar unit 100) to the side of the anti-collision beam 400 facing the vehicle body, i.e., directly behind the anti-collision beam 400.

[0040] In other words, through the cooperation of the base 301 and the flipping component, the flipping mechanism 300 realizes the rapid transfer of the overall position of the protective mechanism 200. While the vehicle's control system precisely controls the upper guard 201 and the lower guard plate 202 to close to each other, the mounting seat 203 flips synchronously toward the side of the anti-collision beam 400 toward the vehicle body, transferring the radar unit 100 from the collision danger zone to the safe area behind the anti-collision beam 400, providing a second layer of protection for the radar unit 100.

[0041] According to one embodiment provided by the present invention, such as Figure 1 , Figure 2 and Figure 5 As shown, the flipping assembly includes a rotating rod 302, a flipping motor 303, a drive gear 304, and a flipping gear 305; The base 301 and the mounting seat 203 are rotatably connected by a rotating rod 302. A flip gear 305 is sleeved on the outer side of the rotating rod 302, and the flip gear 305 rotates synchronously with the rotating rod 302. The base 301 is equipped with a flip motor 303, the output end of the flip motor 303 is connected to the drive gear 304, and the drive gear 304 is meshed with the flip gear 305.

[0042] In this embodiment, the base 301 and the mounting seat 203 are rotatably connected by a rotating rod 302, which is the axis of rotation for the mounting seat 203 to rotate relative to the base 301. The rotating rod 302 passes through corresponding hinge holes on the base 301 and the mounting seat 203, hinged together. A flip gear 305 is sleeved on the outer side of the rotating rod 302, and the flip gear 305 rotates synchronously with the rotating rod 302. The flip gear 305 can be fixedly connected to the rotating rod 302 or integrally formed with the rotating rod 302.

[0043] Specifically, the flip motor 303 is fixedly mounted on the base 301. The output end of the flip motor 303 is connected to the drive gear 304, and the drive gear 304 is meshed with the flip gear 305. When the flip motor 303 is started, its output end drives the drive gear 304 to rotate. The drive gear 304 drives the flip gear 305 to rotate through meshing. The flip gear 305 drives the rotating rod 302 to rotate. The rotating rod 302 drives the mounting seat 203 to rotate around the axis of the rotating rod 302, thereby realizing the overall flipping of the protective mechanism 200.

[0044] Correspondingly, the gear ratio between the tilting gear 305 and the driving gear 304 determines the transmission ratio, which can be set according to the required tilting speed and driving torque. By controlling the rotation angle of the tilting motor 303, the tilting position of the mounting seat 203 can be precisely controlled.

[0045] According to one embodiment provided by the present invention, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the base 301 includes a first connecting ear 306, and the mounting base 203 includes a second connecting ear 207; At least two first connecting ears 306 are spaced apart at the bottom of the base 301, and at least two second connecting ears 207 are spaced apart at the top of the mounting seat 203; The first connecting ear 306 has a mounting hole, and the flip motor 303 is installed in the mounting hole; The first connecting ear 306 is also provided with a first rotating hole, and the second connecting ear 207 is provided with a second rotating hole at the corresponding position of the first rotating hole. The rotating rod 302 passes through the corresponding first rotating hole and second rotating hole in sequence.

[0046] In this embodiment, at least two first connecting ears 306 are spaced apart at the bottom of the base 301, meaning the first connecting ears 306 extend downward from the main body of the base 301. At least two second connecting ears 207 are spaced apart at the top of the mounting seat 203, meaning the second connecting ears 207 extend upward from the mounting seat 203. The positions of the first connecting ears 306 and the second connecting ears 207 correspond to each other and are staggered and fitted during assembly. Furthermore, a mounting hole is provided in the first connecting ear 306, and the flip motor 303 is mounted in this mounting hole. The size and shape of the mounting hole match the housing of the flip motor 303, securely accommodating and positioning the flip motor 303.

[0047] Correspondingly, the first connecting ear 306 also has a first rotating hole, and the second connecting ear 207 has a second rotating hole at the corresponding position of the first rotating hole. The rotating rod 302 passes through the corresponding first rotating hole and second rotating hole in sequence, hinged together the base 301 and the mounting seat 203. The staggered arrangement of multiple first connecting ears 306 and second connecting ears 207 provides multi-point support, making the hinged connection more stable.

[0048] In actual assembly, multiple first connecting ears 306 and second connecting ears 207 are staggered and aligned so that all rotating holes are on the same straight line. Then, the rotating rod 302 is passed through all the rotating holes in sequence to complete the hinge. The staggered arrangement of the connecting ears ensures uniform force distribution and avoids stress concentration. Limiting structures (such as shoulders or retaining rings) can be set at both ends of the rotating rod 302 to prevent axial movement of the rotating rod 302.

[0049] According to one embodiment provided by the present invention, such as Figure 1 , Figure 2 and Figure 3 As shown, the radar unit 100 includes a front shroud 101, a rear shroud 102, a rotary motor 103, and a radar assembly. The rear cover 102 forms a receiving cavity with an opening at one end, and the front cover 101 covers the opening to close the receiving cavity; The cavity contains a rotary motor 103 and a radar assembly. The output of the rotary motor 103 is connected to the radar assembly for transmission. The rotary motor 103 drives the radar assembly to rotate along the direction of the cross-section of the front cover 101.

[0050] In this embodiment, the front shield 101 and the rear shield 102 together form a closed installation space for the radar 105, providing basic protection for the radar 105 and the rotary motor 103 inside. Both the front shield 101 and the rear shield 102 are made of plastic material, which will not obstruct or interfere with the radar 105's waves or laser. The rotary motor 103 and the radar assembly are housed within the cavity. The output of the rotary motor 103 is connected to the radar assembly, and the rotary motor 103 can drive the radar assembly to rotate along the direction of the cross-section of the front shield 101 (i.e., the horizontal direction). This rotational movement allows the radar 105 to scan in the horizontal direction, covering a larger detection range.

[0051] Specifically, the rotary motor 103 is fixedly mounted on the inner wall of the rear cover 102, and its output shaft is connected to the radar assembly through a transmission mechanism. When the rotary motor 103 rotates, it drives the radar assembly to reciprocate in the horizontal direction, thereby achieving horizontal scanning. By controlling the rotation angle and speed of the rotary motor 103, the scanning range and scanning speed of the radar 105 can be precisely controlled.

[0052] According to one embodiment provided by the present invention, such as Figure 1 , Figure 2 and Figure 3 As shown, the radar assembly includes a bracket 104 and a radar 105; The bracket 104 is rotatably connected to the inner bottom wall of the rear cover 102. The radar 105 is installed on the side of the bracket 104 facing the front cover 101. The output end of the rotary motor 103 is connected to the bracket 104 for transmission.

[0053] In this embodiment, the bracket 104 is rotatably connected to the inner bottom wall of the rear cover 102, meaning the bracket 104 can rotate relative to the rear cover 102 about a vertical axis. A radar 105 is mounted on the side of the bracket 104 facing the front cover 101, and the radar 105 rotates synchronously with the bracket 104. The output end of the rotary motor 103 is connected to the bracket 104 for transmission. When the rotary motor 103 rotates, it drives the bracket 104 to rotate about a vertical axis, causing the radar 105 mounted on it to rotate synchronously.

[0054] The specific structure of the bracket 104 needs to ensure the stability of the radar 105 installation and the smoothness of its rotation. The bracket 104 can be made of aluminum alloy or engineering plastic, possessing sufficient rigidity and lightweight characteristics. The transmission between the rotary motor 103 and the bracket 104 can be a direct drive (the output shaft of the rotary motor 103 is directly connected to the bracket 104) or an indirect drive (through gears or synchronous belts). The direct drive method has a simple structure and high transmission efficiency, making it suitable for applications requiring high response speed.

[0055] With the bracket 104 in place, the installation and rotation of the radar 105 within the housing cavity are more stable and reliable. The bracket 104, acting as an intermediate connector, transmits the driving force of the rotary motor 103 to the radar 105, while also providing a stable mounting surface for the radar 105, ensuring the attitude stability of the radar 105 during rotation and thus guaranteeing scanning accuracy.

[0056] According to one embodiment provided by the present invention, such as Figure 1 , Figure 2 and Figure 3 As shown, the bracket 104 includes vertically arranged horizontal and vertical plates; The horizontal plate is located on the inner bottom wall of the rear cover 102. The horizontal plate has a rotating hole. One end of the rotating shaft passes through the rotating hole and is connected to the rear cover 102. The other end of the rotating shaft is connected to the output end of the rotary motor 103 for transmission. The radar 105 is mounted on the side of the vertical plate facing the front shield 101.

[0057] In this embodiment, the horizontal plate is located on the inner bottom wall of the rear cover 102, and the horizontal plate is parallel to the inner bottom wall of the rear cover 102. The horizontal plate has a rotating hole, one end of which passes through the rotating hole and is connected to the rear cover 102, and the other end of which is connected to the output end of the rotary motor 103. The horizontal plate serves as the bottom support part of the bracket 104, bearing the weight of the entire bracket 104 and the radar 105, and is rotatably connected to the rear cover 102 through the rotating shaft.

[0058] A radar 105 is mounted on the side of the vertical plate facing the front shroud 101. The vertical plate extends vertically upward from one end of the horizontal plate, forming an L-shaped structure. The radar 105 is fixedly mounted on the front surface of the vertical plate, with its detection direction facing the front shroud 101.

[0059] The rotating shaft passes through a rotating hole in the horizontal plate, and its lower end is connected to the inner bottom wall of the rear cover 102 via a bearing, while its upper end is connected to the output end of the rotary motor 103. When the rotary motor 103 rotates, the rotating shaft drives the horizontal plate to rotate, the horizontal plate drives the vertical plate to rotate, and the vertical plate drives the radar 105 on it to rotate synchronously.

[0060] The L-shaped structure with horizontal and vertical plates arranged vertically ensures that the detection direction of the radar 105 is parallel to the horizontal plane. At the same time, the L-shaped structure has high structural rigidity while ensuring strength, and can resist vibration during vehicle operation.

[0061] Example 2 like Figure 10 As shown, the present invention provides a car including the above-described vehicle radar assembly.

[0062] In this embodiment, the vehicle includes the aforementioned vehicle-mounted radar assembly. The vehicle-mounted radar assembly is located at the front and / or rear of the vehicle, between the anti-collision beam 400 and the bumper skin, and is used to monitor the surrounding environment of the vehicle in real time, providing environmental perception data for the driver assistance system.

[0063] In this vehicle, the base 301 of the vehicle-mounted radar assembly is fixedly connected to the anti-collision beam 400. Under normal driving conditions, the upper shield 201 and lower shield 202 of the protective mechanism 200 are in the open position, exposing the radar unit 100. The rotary motor 103 drives the radar 105 to perform horizontal scanning, while the tilting motor 303 on the base 301 drives the entire protective mechanism 200 to swing vertically via a drive gear, achieving vertical scanning. Through the combination of horizontal and vertical scanning, such as... Figure 6 and Figure 7 As shown, a single Radar 105 system can achieve a wide field of view coverage of 180° horizontally and -20° to 30° vertically.

[0064] When radar 105 detects an impending collision, the vehicle's control system immediately activates the protection program. First, the actuator motor 204 of the protection mechanism 200 starts, driving the upper shield 201 and lower shield 202 to flip and close synchronously via gear transmission, enclosing the radar unit 100 within the protected area. Simultaneously, the flipping motor 303 of the flipping mechanism 300 starts, driving the mounting rear seat 203 to flip 180° backward around the hinge axis, flipping the entire protection mechanism 200 from in front of the anti-collision beam 400 to directly behind it. At this point, the radar unit 100 is enclosed within the protected area formed by the high-strength steel upper shield 201, lower shield 202, and mounting rear seat 203, and is located behind the anti-collision beam 400, receiving double protection.

[0065] In the event of a low-speed collision, the impact force is initially absorbed by the bumper skin and the anti-collision beam 400. If the collision energy does not cause the anti-collision beam 400 to collapse, the radar 105 assembly remains intact and requires no repair. If the collision energy is large enough to cause the anti-collision beam 400 to collapse, since the upper shield 201, lower shield 202, and mounting base 203 of the protective mechanism 200 are all made of high-strength hot-formed steel plates, which are stronger than the aluminum alloy anti-collision beam 400, the collapse of the anti-collision beam 400 will not compress the internal space of the protected area, and the radar unit 100 remains intact. In this case, only low-cost components such as the deformed upper shield 201, lower shield 202, or mounting base 203 need to be replaced; the core module of the radar 105 does not need to be replaced, significantly reducing maintenance costs.

[0066] By integrating the aforementioned vehicle-mounted radar assembly into the automobile, the vehicle not only possesses a wide-range radar 105 scanning and detection capability, but also has an active radar 105 protection capability in the event of a collision, effectively solving the technical problems of radar 105 vulnerability and high maintenance costs in traditional radar 105 layout schemes.

[0067] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
