Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a front bumper radar bracket. Background Technology

[0002] With the development of vehicle technology, vehicles are becoming increasingly intelligent. Radar technology is indispensable in areas such as driver assistance, parking assistance, and active safety. Corner radar is an essential component for vehicle systems to achieve functions such as driver assistance, collision warning, and pedestrian detection.

[0003] Corner radars are typically mounted on the front bumper skin of a car, and are usually fixed to the front bumper skin using a radar bracket with a bolt structure.

[0004] However, the front bumper skin of the vehicle is relatively thin and soft, and the radar itself has a certain weight, making it prone to vibration during driving. In particular, the bumps during driving are difficult to predict and control, which can easily cause the vehicle to shake in multiple directions such as up and down and left and right. The radar is also prone to vibration along with the bracket and the front bumper skin, which can easily lead to loosening of the connection between the radar and the front bumper, and even shorten the service life of the radar. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a front bumper radar bracket, which aims to solve the problem that radar installed on the front bumper is easily affected by vibration during driving, resulting in loose connection and shortened radar life.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] A front bumper radar bracket includes two first damping mechanisms and a second damping mechanism. Each first damping mechanism includes a first base, a second base, a first connecting portion, a second connecting portion, and a first fixing seat. One end of the first base is rotatably connected to the first connecting portion, and the end of the first connecting portion facing away from the first base is rotatably connected to the first fixing seat. The end of the first fixing seat facing away from the first connecting portion is rotatably connected to the second connecting portion, and the end of the second connecting portion facing away from the first fixing seat is rotatably connected to the second base. Both the first and second bases are used to connect to the front bumper. The second damping mechanism includes a third base, a fourth base, a third connecting portion, a fourth connecting portion, and a second fixing seat. The top ends of the two first fixing seats are respectively connected to the third base and the fourth base. The third base is rotatably connected to the third connecting portion, and the end of the third connecting portion facing away from the third base is rotatably connected to the second fixing seat. The second fixing seat faces away from the third connecting portion. One end of the first connecting part is rotatably connected to the fourth connecting part, and the end of the fourth connecting part facing away from the second fixed seat is rotatably connected to the fourth base. The first fixed seat includes a fixed plate and two fixed abutments. The two fixed abutments are respectively connected to the two ends of the fixed plate. The first connecting part includes a first connecting plate, a second connecting plate, and a first limiting plate. The first connecting plate and the second connecting plate are arranged opposite to each other. The first connecting plate and the second connecting plate are respectively rotatably connected to the two sides of the first fixed seat. The first limiting plate is connected between the first connecting plate and the second connecting plate. The first limiting plate and the fixed abutments are positioned correspondingly. The included angle between the first limiting plate and the fixed abutments is an acute angle. A buffer strip is provided on the side of the fixed abutment facing the first limiting plate. The buffer strip abuts against the first limiting plate. The second fixed seat has the same structure as the first fixed seat. The second connecting part, the third connecting part, and the fourth connecting part all have the same structure as the first connecting part.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting two first damping mechanisms and a second damping mechanism, the front bumper radar bracket has damping capability in multiple directions. When the first damping mechanism shakes, there is a tendency for rotation between the first base and the first connecting part, the first connecting part and the first fixed seat, the first fixed seat and the second connecting part, and the second connecting part and the second base. The first limiting plate in the first connecting part limits the rotation between the first fixed seat and the first connecting part. Specifically, the maximum rotation angle is limited by the fixed abutment plate. The maximum angle that the included angle between the fixed seat and the first connecting part can increase during rotation is the included angle between the fixed abutment and the first limiting plate. During rotation, the buffer strip between the fixed abutment and the first limiting plate provides shock absorption. Similarly, the same applies between the first fixed seat and the second connecting part. The second shock absorption mechanism has the same structure as the first shock absorption mechanism and also has a shock absorption function. This prevents the traditional rigid connection bracket from directly transmitting the vibration of the front bumper to the radar. By reducing the vibration force through small-amplitude, buffered rotation, the connection between the radar and the front bumper is prevented from loosening after long-term use, thus extending the service life of the radar in long-term vibration environments.

[0009] Furthermore, the first connecting part also includes a second limiting plate, the second limiting plate is connected between the first connecting plate and the second connecting plate, the second limiting plate corresponds to the position of the first base, and a first connecting hole is opened on the end of the first connecting plate facing the first base and the end of the second connecting plate facing the first base. The first connecting part is rotatably connected to the first rotating shaft through the two first connecting holes.

[0010] Furthermore, the first base includes a mounting plate, a first side plate, a second side plate, and a base abutment. The mounting plate is connected to the first side plate and the second side plate on opposite sides, respectively. A first shaft hole is formed on the first side plate and passes through the first side plate. A second shaft hole is formed on the second side plate and passes through the second side plate. The first rotating shaft passes through the first shaft hole and the second shaft hole.

[0011] Furthermore, the mounting plate is connected to the base abutment at one end facing the first connecting part. The base abutment corresponds to the position of the second limiting plate. The included angle between the base abutment and the second limiting plate is an acute angle. An auxiliary buffer strip is provided on the side of the base abutment facing the second limiting plate, and the auxiliary buffer strip abuts against the second limiting plate.

[0012] Furthermore, a second connecting hole is provided on one end of the first connecting plate facing the first fixed seat and on one end of the second connecting plate facing the first fixed seat. The first connecting part is rotatably connected to the second rotating shaft through the two second connecting holes. The first fixed seat also includes a first fixed side plate and a second fixed side plate. The first fixed side plate and the second fixed side plate are respectively connected to opposite sides of the fixed plate. A first fixed seat shaft hole is provided on one end of the first fixed side plate facing the first connecting part, and a second fixed seat shaft hole is provided on one end of the second fixed side plate facing the first connecting part. The second rotating shaft passes through the first fixed seat shaft hole and the second fixed seat shaft hole.

[0013] Furthermore, the first fixing seat and the second fixing seat are perpendicular to each other in the horizontal direction.

[0014] Furthermore, the second mounting base is connected to a radar mounting plate, which has several radar mounting holes.

[0015] Furthermore, the radar mounting plate is connected to several reinforcing plates, and the reinforcing plates are connected to the second fixing base.

[0016] Furthermore, the mounting plate has several punched holes that penetrate the mounting plate. Attached Figure Description

[0029] Please see Figures 1 to 5 The front bumper radar bracket in this embodiment of the present invention includes two first damping mechanisms and a second damping mechanism. The first damping mechanism includes a first base 100, a second base 200, a first connecting part 310, a second connecting part 320, and a first fixing seat 500. One end of the first base 100 is rotatably connected to the first connecting part 310. The end of the first connecting part 310 facing away from the first base 100 is rotatably connected to the first fixing seat 500. The end of the first fixing seat 500 facing away from the first connecting part 310 is rotatably connected to the second connecting part 320. The end of the second connecting part 320 facing away from the first fixing seat 500 is rotatably connected to the second base 200. Both the first base 100 and the second base 200 are used to connect to the front bumper. Preferably, the first shock-absorbing mechanism is symmetrical about the central axis of the first fixed base 500. Understandably, when the first shock-absorbing mechanism is affected by vibration, the first base 100 and the first connecting part 310, the first connecting part 310 and the first fixed base 500, the first fixed base 500 and the second connecting part 320, and the second connecting part 320 and the second base 200 will all rotate relative to each other.

[0030] The first connecting portion 310 includes a first connecting plate 311, a second connecting plate 312, a first limiting plate 313, and a second limiting plate 314. The first connecting plate 311 and the second connecting plate 312 are disposed opposite to each other. The first connecting plate 311 and the second connecting plate 312 are rotatably connected to both sides of the first fixing seat 500. The first limiting plate 313 and the second limiting plate 314 are connected between the first connecting plate 311 and the second connecting plate 312. The first limiting plate 313 corresponds to the position of the first fixing seat 500, and the second limiting plate 314 corresponds to the position of the first fixing seat 500. Corresponding to the base 100, both the first connecting plate 311 facing the first base 100 and the second connecting plate 312 facing the first base 100 have first connecting holes 315. The first connecting part 310 is rotatably connected to the first rotating shaft 410 through the two first connecting holes 315. Both the first connecting plate 311 facing the first fixed seat 500 and the second connecting plate 312 facing the first fixed seat 500 have second connecting holes. The first connecting part 310 is rotatably connected to the second rotating shaft 420 through the two second connecting holes. Preferably, both the first limiting plate 313 and the second limiting plate 314 are rectangular plates.

[0031] The first fixing base 500 includes a fixing plate 510, a first fixing side plate 520, a second fixing side plate, and two fixing abutments 530. The two ends of the fixing plate 510 are respectively connected to the two fixing abutments 530. The first limiting plate 313 is positioned corresponding to the fixing abutments 530. The included angle between the first limiting plate 313 and the fixing abutments 530 is an acute angle. A buffer strip 920 is provided on the side of the fixing abutment 530 facing the first limiting plate 313. The buffer strip 920 abuts against the first limiting plate 313. The first fixing side plate 520 and the second fixing side plate are respectively connected to opposite sides of the fixing plate 510. A first fixing base shaft hole is opened on the end of the first fixing side plate 520 facing the first connecting part 310. A second fixing base shaft hole is opened on the end of the second fixing side plate facing the first connecting part 310. The second rotating shaft 420 passes through the first fixing base shaft hole and the second fixing base shaft hole. Understandably, the first fixing seat 500 and the first connecting part 310 are composed of several plates, which helps to reduce the weight of the front bumper radar bracket. The rotating connection is formed by the shaft passing through the shaft hole, which facilitates the disassembly, assembly and maintenance of the front bumper radar bracket.

[0032] The first base 100 includes a mounting plate 110, a first side plate 120, a second side plate 130, and a base abutment 140. The mounting plate 110 connects to the first side plate 120 and the second side plate 130 on opposite sides. A first shaft hole 121 is formed in the first side plate 120, penetrating through it. A second shaft hole 131 is formed in the second side plate 130, penetrating through it. The first rotating shaft 410 passes through the first shaft hole 121 and the base abutment 140. The mounting plate 110 has a two-axis hole 131. One end of the mounting plate 110 facing the first connecting part 310 is connected to the base abutment 140. The base abutment 140 is positioned corresponding to the second limiting plate 314. The included angle between the base abutment 140 and the second limiting plate 314 is an acute angle. An auxiliary buffer strip is provided on the side of the base abutment 140 facing the second limiting plate 314. The auxiliary buffer strip abuts against the second limiting plate 314. A plurality of punch holes 101 are formed on the mounting plate 110, and the punch holes 101 penetrate the mounting plate 110. Preferably, the gap between the first limiting plate 313 and the fixed abutment plate 530 forms an interference fit with the buffer strip 920, and the gap between the second limiting plate 314 and the base abutment plate 140 is similar to that of the auxiliary buffer strip, so that the first shock-absorbing mechanism is installed and secured in a static state, avoiding loosening of the first shock-absorbing mechanism due to installation errors. Both the buffer strip 920 and the auxiliary buffer strip are made of TPU material. The second base 200 and the second connecting part 320 are rotatably connected by a third rotating shaft 430, and the first fixed base 500 and the second connecting part 320 are rotatably connected by a fourth rotating shaft 440. The first rotating shaft 410, the second rotating shaft 420, the third rotating shaft 430 and the fourth rotating shaft 440 are all parallel to each other.

[0033] Please see Figure 4When the first fixed base 500 in the first shock-absorbing mechanism wobbles to the left, the components within the first shock-absorbing mechanism drive each other. Both the first connecting part 310 and the second connecting part 320 rotate counterclockwise. That is, the angle between the first fixed base 500 and the first connecting part 310 increases, while the angle between the first fixed base 500 and the second connecting part 320 decreases. The limiting plate in the second connecting part 320 corresponding to the first fixed base 500 rotates away from the fixed abutment 530. Similarly, the limiting plate in the second connecting part 320 corresponding to the second base 200 rotates away. At this time, the fixed abutment 530 corresponding to the second connecting part 320 is not limited. However, when the angle between the first fixed base 500 and the first connecting part 310 increases, the angle between the fixed abutment 530 corresponding to the first connecting part 310 and the first limiting plate 313 decreases. The fixed abutment 530 then creates a limiting effect with the buffer strip 920 and the first limiting plate 313, compressing the buffer strip 920. Please refer to [link to relevant documentation]. Figure 5 The fixed abutment 530 constrains the rotational travel of the first limiting plate 313, and the buffer strip 920 also prevents the first limiting plate 313 from rotating further, thus forming a buffer. The second limiting plate 314 works similarly to the base abutment 140. Since the first base 100 is fixedly installed on the front bumper, the rotation of the first connecting part 310 is restricted, and the positional change of the first fixed base 500 relative to the first base 100 is also restricted, thereby preventing the first fixed base 500 from swaying further to the left. It can be understood that the first fixed base 500 and the first connecting part 310 can rotate relatively slightly during vibration, while the rotation process is restricted. The first connecting part 310 works similarly to the first base 100, which can prevent the bracket shape from changing too much and prevent the radar position from changing significantly during vibration, while forming a buffering effect, effectively preventing the hard connection from directly transmitting vibration to the radar. Through small rotation and buffering, the first damping mechanism has a strong damping capability.

[0034] The second shock-absorbing mechanism includes a third base 610, a fourth base 620, a third connecting part 710, a fourth connecting part 720, and a second fixing seat 800. The top ends of the two first fixing seats 500 are respectively connected to the third base 610 and the fourth base 620. The third base 610 is rotatably connected to the third connecting part 710. The end of the third connecting part 710 facing away from the third base 610 is rotatably connected to the second fixing seat 800. The end of the second fixing seat 800 facing away from the third connecting part 710 is rotatably connected to the fourth connecting part 720. The end of the fourth connecting part 720 facing away from the second fixing seat 800 is rotatably connected to the fourth base 620. The second fixing seat 800 has the same structure as the first fixing seat 500. The second connecting part 320, the third connecting part 610, and the fourth connecting part 620 all have the same structure as the first connecting part 310. The first fixing seat 500 and the second fixing seat 800 are perpendicular to each other in the horizontal direction. Preferably, the third base 610 and the third connecting part 710 are rotatably connected via a fifth rotating shaft 450, the third connecting part 710 and the second fixed seat 800 are rotatably connected via a sixth rotating shaft 460, the second fixed seat 800 and the fourth connecting part 720 are rotatably connected via a seventh rotating shaft 470, and the fourth connecting part 720 and the fourth base 620 are rotatably connected via an eighth rotating shaft 480. The fifth rotating shaft 450, the sixth rotating shaft 460, the seventh rotating shaft 470, and the eighth rotating shaft are all parallel to each other, and the fifth rotating shaft 450 is perpendicular to the first rotating shaft 410. The second fixed seat 800 includes a fixed top plate 810, two fixed side plates 820, and a top abutment plate 830. A top buffer strip is provided on the top abutment plate 830, which is connected to the fixed abutment plate 830. The structure of 0 and the buffer strip 920 is consistent. The two first damping mechanisms and the second damping mechanism form an H-shaped front bumper radar bracket. The length direction of the first damping mechanism is installed in a direction perpendicular to the horizontal plane. It can be understood that when unpredictable and uncontrollable up-and-down bumps occur during driving, the two first damping mechanisms alleviate the vibration, and the two first damping mechanisms work together to enhance the damping effect. When the vehicle body turns and causes swaying and vibration during driving, the second damping mechanism alleviates the vibration. The front bumper radar bracket has a multi-directional damping effect, which helps to prevent the vibration from being directly transmitted through the fixed connection between the front bumper, bracket and radar. It further prevents the connection between the front bumper and radar from loosening during long-term use and helps to extend the service life of the radar in a vibration environment.

[0035] The second mounting base 800 is connected to the radar mounting plate 900. The radar mounting plate 900 has several radar mounting holes and several reinforcing plates 910 connected to it. The reinforcing plates 910 are connected to the second mounting base 800. Preferably, the radar mounting plate 900 extends from the second mounting base 800 forward towards the bumper, allowing the radar to be close to the skin for better accuracy. The multiple radar mounting holes provide flexible and easily adjustable radar mounting positions. The reinforcing plate 910 is a right-angled triangle, with one right-angled side connected to the radar mounting plate 900 and the other right-angled side connected to the bottom surface of the top mounting plate 810, which helps to make the radar installation more stable.
