Description

Technical Field

[0001] This invention relates to the field of automotive radar installation technology, specifically to a vehicle-mounted radar installation structure with calibration function. Background Technology

[0002] With economic development and the continuous improvement of people's living standards, cars have gradually entered thousands of households, and people are paying more and more attention to driving safety. As a result, more and more automotive driver assistance electronic devices are being applied to cars. These devices utilize various sensors installed on the car to detect environmental data inside and outside the vehicle in real time. If a lane change assist system is installed in a car, it can greatly reduce traffic accidents. However, lane change assist systems require radar detection and a main unit to issue warnings. The radar needs to be fixed to the car body, and during long-term driving, the radar may shift due to driving vibrations, resulting in insufficient radar detection.

[0003] If a lane change assist system is installed on a car, traffic accidents can be greatly reduced. However, the lane change assist system requires radar detection and a main unit to issue warnings. The radar needs to be fixed to the car body. During long-term driving, the radar may be displaced due to driving vibrations, resulting in insufficient radar detection.

[0004] For example, patent publication number CN 211905667 U discloses a vehicle-mounted radar system installation structure, belonging to the field of vehicle-mounted radar system installation structures, providing a vehicle-mounted radar system installation structure capable of adjusting the installation azimuth angle of the radar. It includes a vehicle-mounted profile frame, a fixed base plate, and a rotating base plate. The vehicle-mounted profile frame is used for fixed installation on the vehicle roof, the fixed base plate is mounted on the vehicle-mounted profile frame, and the rotating base plate is mounted on the fixed base plate. The rotating base plate can rotate relative to the fixed base plate to adjust its azimuth angle, and the rotating base plate is used to install the radar. The vehicle-mounted radar system installation structure of this utility model allows for adjustment of the radar's azimuth angle by rotating and adjusting the azimuth angle of the rotating base plate, thereby achieving adjustment of the radar's installation azimuth angle and meeting the need for data acquisition from different radar angles.

[0005] The aforementioned patent still has some problems in use. Although the control of the radar can meet the need for data collection from different angles, it cannot calibrate the radar's position during use. When the radar position shifts, the radar detection position changes, which reduces driving safety. Therefore, there is a need for a vehicle-mounted radar installation structure with calibration function. Summary of the Invention

[0006] The purpose of this invention is to provide a vehicle-mounted radar mounting structure with calibration function. By setting two sets of mounting limit plates to limit the radar housing, and by using movable delivery rollers in conjunction with a rotating turntable, the radar housing can be quickly calibrated and adjusted, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a vehicle-mounted radar mounting structure with calibration function, comprising a radar housing; a radar core board snapped into the radar housing and electrically connected to the radar core board and fixedly mounted on the front side of the radar housing; a cover plate snapped into the upper part of the radar housing and an adjustment assembly mounted on the upper part of the cover plate; a heat dissipation base snapped into the lower side of the radar housing; two sets of mounting limiting plates mounted on the radar housing for protecting and limiting the cover plate and the heat dissipation base, a limiting window opened in the middle of the upper set of mounting limiting plates, an auxiliary assembly movably mounted inside the limiting window; and a second connecting plug for connecting the first connecting plug and a connecting assembly fixedly mounted on the output end of the second connecting plug.

[0008] Preferably, a positioning frame is fixedly installed inside the radar housing, and the radar core board is installed inside the positioning frame; and a positioning assembly is installed on the outside of the positioning frame.

[0009] Preferably, the positioning component includes: two sets of clamping plates that are fitted and snapped together on the upper and lower sides of the positioning frame; protective pads that are fixedly installed at the four corner points inside the clamping plates; the protective pads are disposed against the outer surface of the radar core board; and a plug-in component installed on the outside of the first connecting plug.

[0010] Preferably, the plug-in assembly includes: two sets of side limiting seats symmetrically fitted and installed on the outside of the first connector plug; positioning sockets symmetrically installed on the upper and lower sides of the first connector plug; an elastic retaining plate fixedly installed in the middle of the two sets of positioning sockets; and two sets of upper slots opened downward in the middle of the left and right sides of the radar housing, and two sets of lower slots opened upward on the front and rear sides of each set of upper slots.

[0011] Preferably, it further includes a first connecting plate fixedly installed on the side of the cover plate corresponding to the upper slot; the adjusting assembly includes: a top plate for limiting the rotation disk, a first sliding groove opened in the middle of the top plate, the rotation disk being rotatably installed inside the top plate and passing through the inner groove opened in the middle of the rotation disk; and a limiting protrusion fixedly installed on the front side of the top plate, and a first positioning slot opened on the front side of the cover plate corresponding to the position of the limiting protrusion.

[0012] Preferably, it also includes four sets of second connecting plates fixedly installed on the upper surface of the heat sink base, and a second positioning slot opened on the front side of the heat sink base for snapping into the heat sink module installed inside the heat sink base.

[0013] Preferably, it also includes two sets of mounting limit plates symmetrically arranged vertically, two sets of grooves formed on the outer surface of each set of mounting limit plates, several sets of positioning holes formed through the interior of each set of grooves; and several sets of connecting bolts for connecting the two sets of mounting limit plates.

[0014] Preferably, it further includes two sets of auxiliary springs symmetrically fixedly installed inside the limiting window, positioning blocks installed on both sides of each set of auxiliary springs, and damping push rods fixed to the outside of the positioning blocks; and

[0015] An arc-shaped plate is installed at the telescopic end of the damping push rod.

[0016] Preferably, the auxiliary component includes: a motor box fixedly connected to the two sets of auxiliary springs, each set of arc plates being fitted against the outer arc surface of the motor box, a motor being installed inside the motor box, a control shaft being keyed to the output end of the motor, and delivery rollers being keyed to both ends of the control shaft.

[0017] Preferably, the connecting assembly includes: a protective tube for connecting to the first connecting plug, a limiting inner plate fixedly installed inside the protective tube, a second sliding groove formed on the upper and lower sides of the inner wall of the protective tube, and a positioning slot formed on the upper and lower surfaces of the protective tube.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. By installing two sets of clamping plates inside the radar housing and fitting them to the positioning frame, the lower surface of the protective pad is pressed against the outer side of the radar core board, making the radar core board more stable in use. Furthermore, by limiting the radar core board, the use of the first connector is more stable, thereby ensuring that the first connector and the second connector are connected with less loosening caused by shaking.

[0020] 2. A cover plate located on the upper part of the radar housing seals the radar housing and limits the top plate. A rotating disk located inside the top plate can be used in conjunction with the motor box and the conveyor rollers. The rotation of the conveyor rollers applies additional force to the radar housing, controlling the radar housing to return to a stable position, thereby fixing the radar equipment to capture external signals. A heat dissipation module located at the bottom of the radar core board can effectively dissipate heat from the radar core board, allowing the radar core board to continue to work under high temperature conditions.

[0021] 3. The two sets of mounting limit plates are connected by connecting bolts to limit the radar housing, top plate, and heat dissipation base, providing a stable and safe space for the use of radar components and limiting the use of the motor box. The controllability of the motor box is improved by the limit window opened in the mounting limit plate and the auxiliary spring and damping push rod set inside the limit window, so that the motor box can quickly reset after being moved by force, and the radar components can perform rapid calibration as the motor box resets.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0032] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indicators will also change accordingly.

[0033] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0034] This invention provides: a vehicle-mounted radar mounting structure with calibration function, such as... Figure 1-8 As shown, the system includes a radar housing 1; a radar core board 3 snapped into the radar housing 1 and a first connecting plug 6 fixedly installed on the front side of the radar housing 1 and electrically connected to the radar core board 3; a cover plate 12 snapped into the upper part of the radar housing 1 and an adjustment assembly installed on the upper part of the cover plate 12; a heat dissipation base 20 snapped into the lower side of the radar housing 1; two sets of mounting limit plates 24 installed on the radar housing 1 to protect and limit the cover plate 12 and the heat dissipation base 20, a limit window 28 opened in the middle of the upper mounting limit plate 24, an auxiliary assembly movably installed inside the limit window 28; and a second connecting plug 36 for connecting the first connecting plug 6 and a connecting assembly fixedly installed at the output end of the second connecting plug 36.

[0035] Preferably, a positioning frame 2 is fixedly installed inside the radar housing 1, and the radar core board 3 is installed inside the positioning frame 2; and a positioning component is installed on the outside of the positioning frame 2. The positioning frame 2, which is set inside the radar housing 1, limits the use of the radar core board 3, making the connection between the radar core board 3 and the first connecting plug 6 more stable.

[0036] Furthermore, the positioning component includes: two sets of clamping plates 4 that are fitted and snapped together on the upper and lower sides of the positioning frame 2; protective pads 5 that are fixedly installed at the four corner points inside the clamping plates 4; and a plug-in component installed on the outside of the first connector 6. The two sets of clamping plates 4 on the outside of the positioning frame 2 limit the use of the positioning frame 2. At the same time, the connection between the clamping plates 4 and the positioning frame 2 ensures that the protective pads 5 can press against the outer surface of the radar core plate 3, thereby better limiting the use position of the radar core plate 3 and ensuring the stability of the first connector 6.

[0037] Furthermore, the plug-in assembly includes: two sets of side limiting seats 7 symmetrically fitted and mounted on the outside of the first connector plug 6; positioning sockets 8 symmetrically mounted on the upper and lower sides of the first connector plug 6; and elastic retaining plates 9 fixedly mounted in the middle of the two sets of positioning sockets 8; as well as two sets of upper slots 10 downwardly opened in the middle of the left and right sides of the radar housing 1, and two sets of lower slots 11 upwardly opened on the front and rear sides of each set of upper slots 10. The side limiting seats 7 and positioning sockets 8 mounted on the outside of the first connector plug 6 cooperate with the limiting inner plate 38 and the second sliding groove 39 inside the protective plug tube 37 to ensure that the first connector plug 6 is stably inserted into the protective plug tube 37 and connected to the second connector plug 36 without shaking. The problem is that the connection between the first connector 6 and the second connector 36 is improved. At the same time, the elastically installed elastic plate 9 can spring up and insert into the positioning slot 40 after the first connector 6 is inserted into the protective tube 37, further completing the connection limit of the first connector 6 and the second connector 36, avoiding the situation where the first connector 6 and the second connector 36 are disconnected due to vibration during vehicle operation, thus improving the stability of the first connector 6. The lower slot 11 and cover plate 12 on the side of the radar housing 1 can ensure that the top plate 14 and the heat dissipation base 20 are stably connected to the radar housing 1, improving the protection of the radar core board 3.

[0038] It is worth noting that the system also includes two sets of first connecting plates 13 fixedly installed on the side of the cover plate 12 corresponding to the two sets of upper slots 10; the adjustment assembly includes: a top plate 14 for limiting the rotation disk 16, a first sliding groove 15 opened in the middle of the top plate 14, the rotation disk 16 being rotatably installed inside the top plate 14, and an inner groove 17 passing through the middle of the rotation disk 16; a limiting protrusion 18 fixedly installed on the front side of the top plate 14, a first positioning slot 19 opened on the front side of the cover plate 12 corresponding to the position of the limiting protrusion 18, and the first connecting plates 13 installed on the side of the cover plate 12 engaging with the upper slots 10 to make the cover plate 12 fit against the radar housing 1. The top surface indicates the stability of the connection between the radar housing 1 and the cover plate 12, enabling the adjustment component to better control the adjustment of the radar housing 1 under stress. The first groove 15 opened after the radar housing 1 is inserted into the two sets of mounting limit plates 24 can ensure the mobility of the delivery roller 35, allowing the delivery roller 35 to enter the inner groove 17 opened inside the rotating disk 16. Since the rotating disk 16 is rotatably installed inside the top plate 14, the use angle of the radar housing 1 can be controlled by the movement of the delivery roller 35 inside the inner groove 17 after the radar housing 1 tilts under stress, so that the use position of the radar housing 1 can be corrected.

[0039] Specifically, it also includes four sets of second connecting plates 21 fixedly installed on the upper surface of the heat dissipation base 20, a second positioning slot 22 opened on the front side of the heat dissipation base 20, a heat dissipation module 23 snapped into the heat dissipation base 20, and the second connecting plate 21 at the top of the heat dissipation base 20 snapped into the first connecting plug 6, so that the heat dissipation module 23 set inside the heat dissipation base 20 can stably dissipate heat from the radar core board 3 inside the radar housing 1, thereby ensuring the stability of the radar housing 1 under high temperature conditions. The second positioning slot 22 opened on the front side of the heat dissipation base 20 and the first positioning slot 19 opened on the front side of the cover plate 12 work together to better limit the use and installation position of the first connecting plug 6, so that the device as a whole has stronger force resistance.

[0040] In addition, two sets of mounting limit plates 24 are symmetrically arranged vertically, with two sets of grooves 25 on the outer surface of each set of mounting limit plates 24, and several sets of positioning holes 26 penetrating inside each set of grooves 25; and several sets of connecting bolts 27 for connecting the two sets of mounting limit plates 24. The two sets of mounting limit plates 24 are bolted together by the connecting bolts 27, so that the two sets of mounting limit plates 24 can limit the top plate 14 and the heat dissipation base 20 respectively, further improving the overall stability of the radar housing 1. The grooves 25 can store and protect the connecting bolts 27, reducing the impact of the connecting bolts 27 on the installation and use of the mounting limit plates 24, while the positioning holes 26 penetrating inside the grooves 25 limit the connecting bolts 27, so that the connecting bolts 27 can stably pass through the positioning holes 26 inside the upper and lower sets of mounting limit plates 24 to complete the limitation of the mounting limit plates 24.

[0041] Furthermore, it also includes two sets of auxiliary springs 29 symmetrically installed inside the limiting window 28, positioning blocks 30 installed on both sides of each set of auxiliary springs 29, and damping push rods 31 fixed to the outside of the positioning blocks 30; as well as arc-shaped plates 32 installed at the telescopic ends of the damping push rods 31. The limiting window 28 provides a certain space for the motor box 33 to move, allowing the conveying rollers 35 to move with the swing of the radar housing 1. The auxiliary springs 29 installed inside the limiting window 28 provide limiting support for the use position of the motor box 33. The positioning blocks 30 installed on both sides of the auxiliary springs 29 limit the damping push rods 31, so that the arc-shaped plates 32 installed at the telescopic ends of the damping push rods 31 can stably press against the outer surface of the motor box 33, limiting the motor box 33. The auxiliary springs 29 and damping push rods 31 mainly serve to buffer and reset the motor box 33, thereby better controlling the use state of the conveying rollers 35 to meet the correction and reset of the radar housing 1.

[0042] Furthermore, the auxiliary components include: a motor box 33 fixedly connected to two sets of auxiliary springs 29, each set of arc plates 32 being fitted against the outer arc surface of the motor box 33, a motor being installed inside the motor box 33, a control shaft 34 keyed to the output end of the motor, and a pressing roller 35 keyed to both ends of the control shaft 34. The motor box 33 protects the motor, and the control shaft 34 at the output end of the motor is used to connect to the pressing roller 35, improving the stability of the pressing roller 35 in use. It can control the rotation direction of the pressing roller 35 to apply different forces to the rotating disk 16 at different times, thereby ensuring the calibration work of the radar housing 1.

[0043] It is worth noting that the connecting components include: a protective tube 37 for connecting to the first connecting plug 6, a limiting inner plate 38 fixedly installed inside the protective tube 37, a second sliding groove 39 opened on the upper and lower sides of the inner wall of the protective tube 37, and a positioning slot 40 opened on the upper and lower surfaces of the protective tube 37. The second connecting plug 36 is connected to the first connecting plug 6, which can transmit back the information captured by the radar housing 1, and can also transmit information on the displacement of the radar housing 1. The motor box 33 can be controlled manually to ensure control. The protective tube 37 is used to improve the connection between the first connecting plug 6 and the second connecting plug 36 and reduce the problem of loose connection between the first connecting plug 6 and the second connecting plug 36 after the radar housing 1 is displaced.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
