Description

Technical Field

[0001] This application relates to the field of millimeter-wave radar installation technology, and in particular to a vehicle-mounted millimeter-wave radar installation. Background Technology

[0002] Millimeter-wave radar is a type of radar that operates in the millimeter-wave band. Generally, millimeter waves refer to electromagnetic waves in the 30–300 GHz frequency range with wavelengths of 1–10 mm.

[0003] The function of vehicle-mounted millimeter-wave radar is to enable vehicles to adaptive cruise control and follow the vehicle in front. When there is a possibility of collision between the car and surrounding objects, the warning device will inform the driver or the vehicle to take automatic emergency braking to avoid the collision. When a collision is unavoidable, the system will control the brakes, headrests, seat belts, etc. to reduce the damage caused by the collision.

[0004] Traditional millimeter-wave radars are installed on the front and rear bumpers of a vehicle and are always exposed to the outside world. Even when the car is parked and not in use, the millimeter-wave radar remains exposed to the outside world and is easily scratched or bumped, causing costly damage to the car owner. Summary of the Invention

[0005] To improve the protection of millimeter-wave radar and reduce scratches and bumps, this application provides a vehicle-mounted millimeter-wave radar device.

[0006] This application provides a vehicle-mounted millimeter-wave radar device that adopts the following technical solution:

[0007] A vehicle-mounted millimeter-wave radar device includes a housing for mounting on a vehicle body, a millimeter-wave radar installed inside the housing, a window for exposing the millimeter-wave radar on the housing, a cover plate hinged to the housing for sealing the window, and a drive assembly for controlling the opening and closing of the cover plate on the housing.

[0008] By adopting the above technical solution, the housing is fixedly connected to the vehicle body, and the millimeter-wave radar is installed inside the housing. During vehicle operation, the drive component controls the cover to flip, allowing the millimeter-wave radar to be exposed through the window, thus achieving the effect of monitoring road conditions. When the vehicle is turned off and parked, the drive component controls the cover to flip and block the window, covering the millimeter-wave radar, reducing the millimeter-wave radar's long-term exposure to the outside world, reducing the possibility of the millimeter-wave radar being bumped or maliciously damaged, and thus protecting the millimeter-wave radar.

[0009] Optionally, two cover plates are provided, and the two cover plates are symmetrically arranged about the housing. A sealing gasket is fixedly connected to one end of each cover plate away from its own hinge axis. A magnet is embedded in one of the sealing gaskets, and an iron sheet is embedded in the other sealing gasket.

[0010] By adopting the above technical solution, when the two cover plates are flipped to close, the sealing gaskets on the two cover plates press against each other, and the magnet on one of the sealing gaskets is attracted to the iron sheet inside the other sealing gasket, making the seal between the two cover plates tighter.

[0011] Optionally, the drive assembly includes a push rod hinged to the cover plate, a push block slidably disposed inside the housing, and an electric cylinder disposed on the housing for controlling the sliding of the push block. The push block drives the end of the push rod away from the cover plate to move closer to or away from the window.

[0012] By adopting the above technical solution, the operator starts the electric cylinder to drive the pusher to move, and under the linkage rotation of the connecting rod, the cover plate is flipped, thereby controlling the two cover plates to close or open the window.

[0013] Optionally, a support rod is provided at the end of the push rod away from the cover plate, and a first guide groove is provided on the housing for guiding the support rod. The push block drives the support rod to move closer to or away from the window in the first guide groove. A sliding groove is provided on the push block, and the support rod is inserted into the sliding groove. When the support rod moves toward the window, the cover plate gradually removes its obstruction effect on the window.

[0014] By adopting the above technical solution, the electric cylinder starts and drives the push block to slide. The limiting groove on the push block limits the support rod, so that the movement of the push block can drive the support rod to move closer to or away from the window. Under the linkage of the push rod, the two cover plates are flipped.

[0015] Optionally, the housing is provided with a movable seat that can slide along the moving direction of the push block. A spring is provided within the housing to prevent the movable seat from moving towards the window. A push plate is connected to the push block to push the movable seat towards the window, and the push plate is located on the side of the movable seat away from the push block. When the push plate pushes the support rod to the end of the first guide groove near the window, the push plate abuts against the push plate. A slide block is slidably disposed within the housing towards or away from the window. The cover plate is hinged to the slide block. The movable seat drives the slide block to move via a linkage unit, and the movable seat and the slide block are relative to the window. The opening moves in the opposite direction; a second guide groove is provided on the housing corresponding to the two first guide groove positions. The length direction of the second guide groove is parallel to the sliding direction of the slide block. The ends of the two first guide grooves near the window are inclined in opposite directions and connected to the ends of the second guide grooves near the window. A tension spring is connected between the two support rods. A baffle for preventing the support rod from entering the first guide groove is fixedly connected to the side of the push block away from the window. The slide groove is an oblong groove. One end of the slide groove extends and opens towards the second guide groove. A control unit is provided on the slide block for fixing the support rod and controlling the support rod to move synchronously with the slide block in the second guide groove.

[0016] By adopting the above technical solution, in the initial state, the movable seat is located away from the window under the elastic force of the spring. Under the linkage action of the linkage unit, the slide is located on the side of the housing closer to the window. The push block is set away from the window, so that both support rods are located at the end of the first guide groove away from the window. At this time, both cover plates are in the closed state.

[0017] When both covers need to be opened, the operator activates the electric cylinder to move the push block towards the window, which in turn moves the two support rods towards the window within their corresponding first guide grooves. During this process, the moving base remains stationary, while the two covers gradually open. When the two support rods move to the end of the first guide groove closest to the window, the slides are fixed to the corresponding support rods via the control unit, and both covers are in the open state. Simultaneously, the push plate moves to abut against the side of the moving base away from the window. The push block continues to move towards the window, causing the push plate to push the moving base towards the window, which in turn causes the two slides to move away from the support plate. During the movement of the two slides, the support rods move synchronously with the corresponding slides within the second guide groove, ensuring that the covers do not flip during the movement of the slides, until the two slides move until the covers are completely retracted into the housing, thus retracting the covers and removing the obstruction of the window. By retracting the covers into the housing, the possibility of damage to the covers from external impacts is reduced.

[0018] Optionally, the linkage unit includes a first pulley group and a second pulley group disposed on the housing. The belt transmission direction of the first pulley group is parallel to the sliding direction of the slide block, and the belt transmission direction of the second pulley group is parallel to the sliding direction of the movable seat. A first gear is coaxially fixedly connected to one pulley of the first pulley group, and a second gear is coaxially fixedly connected to one pulley of the second pulley group. The first gear and the second gear mesh with each other, and the pitch circle of the second gear is larger than the pitch circle of the first gear. When the movable seat moves toward the window, it drives the slide block to move away from the window.

[0019] By adopting the above technical solution, when the movable seat moves towards the window, it drives the belt of the second pulley group to rotate. Under the meshing transmission of the first gear and the second gear, the belt of the first pulley group drives the slide to move away from the window. When the movable seat moves away from the window, the transmission of the first pulley group, the second pulley group, and the first and second gears causes the slide to move towards the window. The pitch circle of the second gear is larger than that of the first gear, making the moving distance of the movable seat less than the moving distance of the slide, thereby reducing the space occupied by the movable seat.

[0020] Optionally, the control unit includes a limiting rod fixedly connected to the slide block. The limiting rod extends toward the second guide groove, and a groove is provided at one end of the limiting rod toward the second guide groove. The groove is used to accommodate the support rod. When the slide block moves to one end near the window, the groove communicates with the end of the first guide groove near the window.

[0021] By adopting the above technical solution, when the slide moves to the end of the housing near the window, the groove of the limiting rod aligns with and connects to the end of the first guide groove near the window. When the support rod moves to the end of the first guide groove near the window, the support rod is supported in the groove. Under the limiting occupation of the groove, the support rod is prevented from moving freely in the second guide groove. During the movement of the slide, the limiting rod drives the support rod to move synchronously with the slide in the second guide groove. This ensures that the cover is in the open state during the movement of the slide.

[0022] Optionally, an adjustment plate is hinged inside the housing, and a first adjustment unit for controlling the rotation of the adjustment plate is provided inside the housing. A mounting plate for mounting the millimeter-wave radar is hinged to the adjustment plate, and a second adjustment unit for controlling the rotation of the mounting plate is provided on the adjustment plate. The hinge axis of the adjustment plate is perpendicular to the hinge axis of the mounting plate.

[0023] By adopting the above technical solution, the operator controls the angle of the adjustment plate through the first adjustment unit and the angle of the mounting plate through the second adjustment unit. Since the hinge axis of the adjustment plate is perpendicular to the hinge axis of the mounting plate, it is convenient to make omnidirectional adjustment of the millimeter-wave radar.

[0024] Optionally, the first adjustment unit includes a shaft fixedly connected to the adjustment plate, the adjustment plate being hinged to the housing via the shaft, a worm gear being fixedly connected to one end of the shaft on the same axis, and a worm being rotatably connected inside the housing, the worm gear meshing with the worm.

[0025] By adopting the above technical solution, the operator turns the worm gear, which drives the shaft to rotate under the transmission action of the worm wheel and worm, thereby adjusting the angle of the adjusting plate.

[0026] Optionally, a sleeve is hinged to the adjusting plate, an adjusting bolt is rotatably connected inside the sleeve, a threaded sleeve is threaded onto the adjusting bolt, and the threaded sleeve is hinged to the mounting plate.

[0027] By adopting the above technical solution, the operator can turn the adjusting bolt to move the screw sleeve, thereby changing the distance between the screw sleeve and the sleeve, and thus controlling the angle change of the mounting plate on the adjusting plate.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. By controlling the flipping of the cover plate, the cover plate can block or open the window, thus covering the millimeter-wave radar and reducing the millimeter-wave radar's exposure to the outside world for a long time. This reduces the possibility of the millimeter-wave radar being bumped or maliciously damaged, and protects the millimeter-wave radar.

[0030] 2. The millimeter-wave radar is installed on the side of the mounting plate facing the window. The operator can adjust the angle of the millimeter-wave radar by turning the adjusting bolt and worm gear to control the angle between the adjusting plate and the mounting plate.

[0038] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0039] This application discloses a vehicle-mounted millimeter-wave radar protection device. For example... Figure 1 The vehicle-mounted millimeter-wave radar protection device includes a housing 1 for fixed connection to the vehicle body. The housing 1 is rectangular and its height direction is parallel to the height direction of the vehicle body.

[0040] like Figure 2 and Figure 3 A window 11 is opened at one end along its length. A mounting base 111 is provided inside the housing 1. An adjustment plate 17 is hinged to the mounting base 111 on the surface opposite to the window 11. The hinge axis of the adjustment plate 17 is parallel to the height direction of the housing. A first adjustment unit 2 for controlling the rotation of the adjustment plate 17 is provided inside the housing 1. A mounting plate 18 for mounting a millimeter-wave radar 19 is hinged to the side of the adjustment plate 17 facing the window 11. The hinge axis of the mounting plate 18 is located at the upper end of the adjustment plate 17, and the hinge axis of the mounting plate 18 on the adjustment plate 17 is perpendicular to the hinge axis of the adjustment plate 17 on the housing 1. A second adjustment unit 3 for controlling the rotation of the mounting plate 18 is provided on the adjustment plate 17.

[0041] The first adjustment unit 2 includes a shaft 21 fixedly connected to the side of the mounting plate 18 facing away from the window 11. The mounting plate 18 is hinged to the mounting base 111 via the shaft 21. A worm gear 22 is fixedly connected coaxially to the lower end of the shaft 21. A worm 23 for meshing with the worm gear 22 is vertically rotatably connected to the side of the mounting base 11 facing the window 11. The operator rotates the worm gear 22 by rotating the worm 23, which in turn drives the shaft 21 and the adjustment plate 17 to rotate synchronously.

[0042] The second adjustment unit 3 includes a threaded sleeve 31 hinged to the mounting plate 18, with the hinge axis of the threaded sleeve 31 parallel to the hinge axis of the mounting plate 18 on the adjustment plate 17, and the central axis of the threaded sleeve 31 perpendicular to its hinge axis. An adjusting bolt 33 is coaxially threaded inside the threaded sleeve 31. A sleeve 32 is rotatably connected to one end of the adjusting bolt 33 facing the adjustment plate 17. The sleeve 32 is hinged to the lower end of the adjustment plate 17, and its hinge axis on the adjustment plate 17 is parallel to the hinge axis of the threaded sleeve 31 on the mounting plate 18. The operator moves the threaded sleeve 31 along the adjusting bolt 33 by turning it, thereby adjusting the angle between the mounting plate 18 and the adjustment plate 17.

[0043] The millimeter-wave radar 19 is mounted on the side of the mounting plate 18 facing the window 11. The operator can adjust the angle of the millimeter-wave radar 19 by turning the adjusting bolt 33 and the worm gear 23.

[0044] like Figure 1 and Figure 4 The housing 1 has cover plates 13 hinged to both sides along its width direction, and the hinge axis between the cover plates 13 and the housing 1 is parallel to the height direction of the housing 1. When the window 11 is closed, the two cover plates 13 are parallel to each other, and the sides of the two cover plates 13 away from the corresponding slide 12 are opposite each other. The housing 1 is provided with a drive assembly 4 for controlling the flipping of the two cover plates 13. Each of the two cover plates 13 is fixedly connected to a sealing gasket 14 on the side away from the corresponding slide 12. One sealing gasket 14 has a magnet 15 embedded in it, and the other sealing gasket 14 has an iron sheet 16 embedded in it. When both cover plates 13 are closed, the two sealing gaskets 14 press against each other. At this time, the magnet 15 attracts the iron sheet 16, making the two sealing gaskets 14 fit more tightly, which helps to improve the sealing effect between the two cover plates 13.

[0045] like Figure 5 and Figure 6The drive assembly 4 includes a push rod 41 hinged to the inner wall of the cover plate 13. The hinge axis between the push rod 41 and the cover plate 13 is parallel to the height direction of the housing 1. A cylindrical support rod 42 is fixedly connected to the end of the push rod 41 away from the corresponding cover plate 13. The axis of the support rod 42 is parallel to the width of the housing 1. A first guide groove 43 is provided on the inner bottom wall of the housing 1 at the positions corresponding to the two support rods 42 for the support rods 42 to pass through. The two first guide grooves 43 are inclined at opposite ends near the window 11. The two first guide grooves 43 are symmetrically arranged along the width direction of the housing 1. The support rods 42 move closer to or further away from the window 11 within the corresponding first guide grooves 43.

[0046] A push block 44 is slidably mounted on the inner bottom wall of the housing 1. The sliding direction of the push block 44 is parallel to the length direction of the housing 1. An electric cylinder 45 for controlling the movement of the push block 44 is fixedly connected to the outer bottom wall of the housing 1. Slide grooves 46 are provided at the positions of the two support rods 42 on the side of the push block 44 facing the window 11. The support rods 42 are inserted into the corresponding slide grooves 46. Both slide grooves 46 are oblong grooves, symmetrically arranged about the moving trajectory of the push block 44, and both opposite ends of the slide grooves 46 are open. When the support rod 42 is located at the end of the first guide groove 43 away from the window 11, the cover plate 13 is in a closed state. As the push block 44 moves toward the window 11, it drives the support rod 42 to move toward the window 11 within the corresponding first guide groove 43. When the support rod 42 is located at one end of the first guide groove 43 near the window 11, the support rod 42 disengages from the corresponding slide groove 46. At this time, the cover plate 13 flips outward toward the housing 1 to a fully open state, and the cover plate 13 is parallel to the side wall of the housing 1 in the width direction.

[0047] A movable seat 5 is provided on the inner bottom wall of the housing 1. The movable seat 5 is located on the side of the slide 12 away from the window 11. Multiple guide rods 51 are fixedly connected to the inner bottom wall of the housing 1. The two ends of the guide rods 51 are fixedly connected to the inner bottom wall of the housing 1 through connecting seats. The length direction of the guide rods 51 is parallel to the length direction of the housing 1, and each guide rod 51 passes through the movable seat 5, allowing the movable seat 5 to slide along the length direction of the housing 1. Springs 52 are sleeved on both guide rods 51. The springs 52 are located on the side of the movable seat 5 facing the window 11, and the springs 52 push the movable seat 5 to move away from the window 11. A connecting rod 53 is fixedly connected to the end of the push block 44 facing the movable seat 5. The axis of the connecting rod 53 is parallel to the length direction of the housing 1. The connecting rod 53 passes through the movable seat 5, and a push plate 54 is fixedly connected to the end of the connecting rod 53 that extends out of the movable seat 5. The push plate 54 is used to prevent the movable seat 5 from disengaging from the connecting rod 53. During the process of the pusher block 44 pushing the two support rods 42 to slide within the corresponding first guide grooves 43, the push plate 54 does not abut against the movable seat 5, so that the movable seat 5 remains away from the window 11 under the elastic force of the spring 52. When the pusher block 44 pushes the support rods 42 to the end of the first guide groove 43 near the window 11, the push plate 54 abuts against the side of the movable seat 5 away from the window 11. As the pusher block 44 continues to move, the push plate 54 can drive the movable seat 5 to gradually move towards the window 11.

[0048] Slide seats 12 are slidably mounted on both inner sidewalls of the housing 1 along its width direction, and the sliding direction of the slide seats 12 is parallel to the length direction of the housing 1. The cover plate 13 is hinged to the slide seats 12 on the side near the window 11. The movable seat 5 is connected to the two slide seats 12 through the linkage unit 7. Under the action of the linkage unit 7, the movable seat 5 and the slide seats 12 move in opposite directions.

[0049] The inner bottom wall of the housing 1 has a second guide groove 55 corresponding to the two first guide grooves 43, and the length direction of the second guide groove 55 is parallel to the length direction of the housing 1. The end of the second guide groove 55 facing the window 11 is connected to the end of the first guide groove 43 facing the opening. The push block 44 is flush with the second guide groove 55 on both sides along the width direction of the housing 1, and the opening sections of the two sliding grooves 46 are also flush with the second guide groove 55. When the support rod 42 is located at the end of the first guide groove 43 near the window 11, the support rod 42 is simultaneously located at the end of the second guide groove 55 facing the window 11. A baffle is fixedly connected to the side of the push block 44 away from the window 11 to prevent the support rod 42 from entering the first guide groove 43. When the push block 44 moves to the end of the first guide groove 43 near the window 11 corresponding to the support rod 42, the push block 44 continues to move towards the window 11, causing the support rod 42 to disengage from the slide groove 46, and the baffle blocks the first guide groove 43, restricting the support rod 42 from sliding towards the end of the first guide groove 43 away from the window 11. A tension spring 56 is connected between the two support rods 42, and the tension spring 56 is used to pull the two support rods 42 closer to each other.

[0050] A control unit 6 is fixedly connected to the slide 12 to fix the support rod 42 and control the support rod 42 to move synchronously with the slide 12 in the second guide groove 55. The control unit 6 includes a limiting rod 61 fixedly connected to the slide 12. The end of the limiting rod 61 away from the corresponding slide 12 extends toward the second guide groove 55, and the end of the limiting rod 61 away from the slide 12 has a groove 62 for the support rod 42 to be inserted. When the slide 12 is located at the end near the window 11, the groove 62 on the limiting rod 61 is located at the end of the second guide groove 55 near the window 11, and at this time the groove 62 communicates with the end of the first guide groove 43 near the window 11. When the support rod 42 is inserted into the groove 62, the groove 62 restricts the movement of the support rod 42 in the second guide groove 55. When the slide block 12 moves along the length of the housing 1, the limiting action of the groove 62 of the support rod 42 causes the support rod 42 and the second guide groove 55 to move synchronously, so that the two cover plates 13 remain open.

[0051] In the initial state, the slide 12 is located at the end of the housing 1 near the window 11. When the support rod 42 moves to the end of the first guide groove 43 near the window 11, the support rod 42 is inserted into the groove 62. At this time, the cover plate 13 flips to the unfolded state, and the cover plate 13 is parallel to the side plates on both sides of the housing 1 in the width direction. The baffle blocks the first guide groove 43, restricting the support rod 42 from leaving the first guide groove 43. When controlling the slide 12 to slide, the slide 12 drives the limiting rod 61 and the support rod 42 to move, and the support rod 42 slides synchronously with the slide 12 in the second guide groove 55, so that the cover plate 13 remains parallel to the side plates on both sides of the frame in the width direction during the storage process.

[0052] The linkage unit 7 includes a first pulley group 71 and a second pulley group 72 disposed on the inner bottom wall of the housing 1. The belt transmission direction of both the first pulley group 71 and the second pulley group 72 is parallel to the length direction of the housing 1. Each of the first pulley group 71 and the second pulley group 72 includes two pulleys rotatably connected to the inner bottom wall of the housing 1, with the two pulleys spaced apart along the length direction of the housing 1. A first gear 73 is fixedly connected to one pulley of the first pulley group 71, and a second gear 74 is fixedly connected to one pulley of the second pulley group 72. The first gear 73 and the second gear 74 mesh with each other, and the pitch circle of the second gear 74 is larger than the pitch circle of the first gear 73. A slide 12 is fixedly connected to the belt corresponding to the first pulley group 71, and a movable seat 5 is fixedly connected to the belt corresponding to the second pulley group 72. When the belts of the first pulley group 71 and the second pulley group 72 move, the sliding directions of the slide 12 and the movable seat 5 are opposite.

[0053] In the initial state, spring 52 pushes the movable seat 5 to move away from window 11, so that the movable seat 5 is located at the end of the corresponding guide rod 51 away from window 11, and the slide 12 is located at the end of the housing 1 close to the window. When the movable seat 5 moves towards window 11, it drives the slide 12 to move away from window 11. Since the pitch circle of the second gear 74 is larger than the pitch circle of the first gear 73, the moving distance of the movable seat 5 is less than the moving distance of the slide 12.

[0054] The implementation principle of this application embodiment is as follows: In the initial state, the two support rods 42 are located at the end of the corresponding first guide groove 43 away from the window 11, and the movable seat 5 is located at the end of the guide rod 51 away from the window 11 under the elastic force of the spring 52. At this time, the two sliding seats 12 are located on the side of the housing 1 close to the window 11, the groove 62 on the limiting rod 61 is connected to the end of the first guide groove 43 close to the window 11, and both cover plates 13 are in the closed state.

[0055] When the operator needs to open the two covers 13, the operator activates the electric cylinder 45 to move the push block 44 toward the window 11. During this process, under the limiting action of the slide groove 46 on the support rod 42, the support rod 42 moves toward the window 11 within the corresponding first guide groove 43, causing the two covers 13 to gradually flip outwards from the housing 1. When the support rod 42 moves to the end of the first guide groove 43 near the window 11, the support rod 42 is located within the corresponding recess 62, and both covers 13 flip up to be parallel to the two side walls in the width direction of the housing 1. The push block 44 then moves the push plate 54 to abut against the side of the moving seat 5 away from the window 11.

[0056] The electric cylinder 45 drives the pusher block 44 to move towards the window 11, which in turn drives the pusher plate 54 to push the moving seat 5 towards the window 11. Under the transmission action of the first pulley group 71, the second pulley group 72, the first gear 73, and the second gear 74, the slide 12 moves away from the window 11. The movement of the slide 12 away from the window 11 further drives the limiting rod 61 to move away from the window 11. Under the limiting action of the groove 62 on the support rod 42, the support rod 42 moves away from the window 11 within the corresponding second guide groove 55. This allows the cover plate 13 to maintain a constant angle as it moves away from the window 11 along with the slide 12. The cover plate 13 retracts into the housing 1, achieving the opening effect of the cover plate 13.

[0057] When the operator needs to close the cover plate 13, the operator activates the electric cylinder 45 to move the slide 12 away from the window 11. During this process, the moving seat 5 is attached to the push plate 54 under the elastic force of the spring 52 and moves away from the window 11 with the push plate 54. During this process, under the transmission action of the first pulley group 71, the second pulley group 72, the first gear 73 and the second gear 74, the two slides 12 are moved towards the window 11. When the moving seat 5 moves to the end of the guide rod 51 away from the window 11, the slide 12 moves to the end of the housing 1 close to the window 11. Under the action of the limit rod 61, the support rod 42 moves to the end of the second guide groove 55 close to the window 11. At this time, the push block 44 moves to the slide groove 46 and the groove 62 are aligned. The electric cylinder 45 continues to drive the push rod 41 to move away from the window 11. Under the elastic force of the tension spring 56, the two support rods 42 enter the first guide groove 43 along the slide 46 and move towards the end of the first guide groove 43 away from the window 11 until the two cover plates 13 close the window 11.
