Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a radar protection structure and vehicle. Background Technology

[0002] With the gradual development of vehicle technology, vehicle functionality has become increasingly sophisticated. Currently, vehicles are equipped with radar, such as corner radar, to detect the distance between the vehicle and external obstacles. When the vehicle gets too close to an obstacle, the radar sends a warning to alert the driver and prevent a collision. Traditional vehicles lack corresponding radar protection structures; when a vehicle is involved in a collision, the deformation of the bumper can compress the radar, causing damage and increasing vehicle repair costs. Utility Model Content

[0003] This application provides a radar protection structure and vehicle with better protection effect to solve related technical problems.

[0004] This application provides a radar protection structure for installation between a bumper and a crash beam, wherein a radar is installed between the bumper and the crash beam. The structure includes: a protective member for installation on the crash beam and located to the side of the radar; the protective member includes a force-bearing surface and an assembly surface disposed opposite to each other, the assembly surface being connected to the side of the crash beam facing the bumper; and the thickness of the protective member is greater than the thickness of the radar in the direction from the force-bearing surface to the assembly surface.

[0005] Because the protective component is installed to the side of the radar and its thickness is greater than that of the radar, when the vehicle is involved in a collision, the protective component can be supported between the bumper and the anti-collision beam, forming a protective space and preventing the bumper and the protective component from squeezing the radar, thus providing good protection.

[0006] Furthermore, the protective component is provided with a clearance space, which is aligned with the radar's wiring harness. By providing the clearance space, compression of the wiring harness can be prevented, thus improving the protective effect of the radar protection structure.

[0007] Furthermore, the protective component also includes a first side and a second side connecting the force-bearing surface and the assembly surface; the first side faces the radar, the second side faces away from the radar, and the clearance space is formed by recessing from the second side towards the first side. Because the clearance space is formed by recessing from the second side, it has a larger volume, improving its clearance effect on the wiring harness and further enhancing the protective effect of the radar protection structure.

[0008] Furthermore, the protective component also includes a top surface and a bottom surface connecting the first side surface and the second side surface, and the clearance space is provided through the bottom surface in the direction from the top surface to the bottom surface. The increased volume of the clearance space enhances its clearance effect on the wiring harness, thereby improving the protective effect of the radar protection structure.

[0009] Furthermore, the clearance space includes an opening facing the radar, and the protective member has a rounded corner structure around the opening. By providing the rounded corner structure, cutting the wiring harness is avoided, thus improving the protective capability of the radar protection structure.

[0010] Furthermore, the protective component includes an outer frame and reinforcing ribs connected to the inner sidewall of the outer frame. The reinforcing ribs and the outer frame form weight-reducing holes that pass through the protective component. The outer frame and the reinforcing ribs form a frame structure, improving the strength of the protective component. At the same time, by forming weight-reducing holes, the weight of the protective component is reduced.

[0011] Furthermore, the outer frame includes a first plate and a second plate disposed opposite to each other, and a third plate and a fourth plate connecting the first plate and the second plate. The reinforcing ribs include a first reinforcing rib connecting the first plate and the second plate, and a second reinforcing rib connecting the third plate and the fourth plate. This arrangement improves the strength of the protective component and reduces its weight.

[0012] Furthermore, the protective component is provided with mounting holes extending from the stress-bearing surface to the assembly surface. Screws are fitted into these mounting holes to secure the protective component to the crash beam. By screwing the protective component to the crash beam, structural strength and installation efficiency are improved.

[0013] Furthermore, the mounting hole includes a first section and a second section, the diameter of the first section being larger than that of the second section. The first section is positioned closer to the assembly surface, and the second section is positioned closer to the force-bearing surface. Because the second section has a larger diameter, screw insertion is easier, further improving the installation efficiency of the protective component.

[0014] This application also provides a vehicle, including: a radar, a bumper, a crash beam, and the aforementioned radar protection structure, wherein the protective component is disposed on one side of the radar along the extension direction of the crash beam. Because the radar protection structure of this application has good protective effect, the radar can still function normally when the vehicle is involved in a collision, reducing maintenance costs.

Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0030] Traditional vehicles lack adequate radar protection structures. When a vehicle is involved in a collision, the deformation of the bumper can compress the radar, causing damage and increasing vehicle repair costs. National regulations also require that functional components of the bumper continue to function after a collision. This application provides a radar protection structure and vehicle to solve these technical problems.

[0031] like Figure 1 As shown, in the relevant tests, a collision block 50 is set up, and the vehicle actively impacts it to simulate the collision process. Figures 1 to 4As shown, this application provides a vehicle including a radar 10, a bumper 20, a crash beam 30, and a radar protection structure. The radar 10 is disposed between the bumper 20 and the crash beam 30. The radar protection structure, which is disposed between the bumper 20 and the crash beam 30, includes a protective member 40. The protective member 40 is disposed on the crash beam 30 and located laterally to the radar 10. The bumper 20 and the crash beam 30 are spaced apart in the horizontal direction. The radar 10 is mounted on the side of the bumper 20 facing the crash beam 30.

[0032] Please refer to the following: Figure 5 and Figure 6 As shown, the radar 10 includes a main body 11 and a wiring harness 12. The bumper 20 can be a front bumper or a rear bumper. Correspondingly, the anti-collision beam 30 can be a front anti-collision beam or a rear anti-collision beam. The anti-collision beam 30 includes a first end 301 and a second end (not shown in the figure). The protective member 40 is installed to the first end 301. The radar 10 is located near the first end 301. The radar 10 is disposed on the side of the protective member 40 facing the second end.

[0033] Please refer to the following: Figure 7 As shown, the protective component 40 includes a load-bearing surface 401, an assembly surface 402, a first side surface 403, a second side surface 404, a top surface 405, and a bottom surface 406. The load-bearing surface 401 and the assembly surface 402 are arranged opposite to each other. The assembly surface 402 is used to connect to the side of the anti-collision beam 30 facing the bumper 20. In the direction from the load-bearing surface 401 to the assembly surface 402, the thickness of the protective component 40 is greater than the thickness of the radar 10.

[0034] Because the protective component 40 is installed to the side of the radar 10 and its thickness is greater than that of the radar 10, when the vehicle is involved in a collision, the protective component 40 can support the radar 10 between the bumper 20 and the anti-collision beam 30, forming a protective space. This prevents the deformation and compression of the bumper 20 from affecting the radar 10, thus providing good protection. At the same time, the protective component 40 avoids the radar 10, preventing the protective component 40 itself from affecting the radar 10, thereby improving the protective effect of the radar protection structure.

[0035] Specifically, the protective component 40 can be located on the side of the radar 10 facing the first end 301. The protective component 40 can also be located on the side of the radar 10 facing the second end. In other embodiments, the protective component 40 can also be located above or below the radar 10 in the height direction. Because the radar protection structure of this application has a good protective effect, the radar 10 can still function normally when the vehicle is involved in a collision, reducing maintenance costs. The vehicle in this application can be an electric vehicle, a gasoline vehicle, or a hybrid vehicle; the specific vehicle type is not limited.

[0036] During the test, along Figure 1In the direction indicated by the middle arrow, the collision block 50 collides with the vehicle at a relative speed of 30 km / h, the bumper 20 collapses, and the force-bearing surface 401 comes into contact with the collapsed bumper 20. Due to the large thickness of the protective component 40, it can play a supporting role, preventing the bumper 20 from squeezing the radar 10 and ensuring that the radar 10 is not damaged.

[0037] The wiring harness 12 extends from the main body 11 toward the first end 301. The protective component 40 is provided with a clearance space 400, which is aligned with the wiring harness 12. By providing the clearance space 400, compression of the wiring harness 12 can be prevented, thus improving the protective effect of the radar protection structure.

[0038] The first side surface 403 and the second side surface 404 connect the force-bearing surface 401 and the assembly surface 402. The first side surface 403 is located close to the first end 301. The second side surface 404 is located away from the first end 301. A clearance space 400 is formed by recessing from the second side surface 404 toward the first side surface 403.

[0039] Since the clearance space 400 is formed by the recess from the second side 404, the clearance space 400 has a large volume, which improves the clearance space 400's clearance effect on the wire harness 12 and further improves the protection effect of the radar protection structure.

[0040] The top surface 405 and the bottom surface 406 connect the first side surface 403 and the second side surface 404. A clearance space 400 is provided through the bottom surface 406. The increased volume of the clearance space 400 enhances its clearance effect on the wire harness 12, thereby improving the protection effect of the radar protection structure.

[0041] The clearance space 400 includes an opening 4001 facing the second end. The protective member 40 has a rounded corner structure 4002 around the opening 4001. By providing the rounded corner structure 4002, cutting the wire harness 12 is avoided, thus improving the protective capability of the radar protection structure.

[0042] Please refer to the following: Figure 8 As shown, the protective component 40 includes an outer frame 41 and a reinforcing rib 42. The reinforcing rib 42 is connected to the inner wall of the outer frame 41. The reinforcing rib 42 and the outer frame 41 form a weight-reducing hole 43 passing through the protective component 40. The outer frame 41 and the reinforcing rib 42 form a frame structure, which improves the strength of the protective component 40. At the same time, by forming the weight-reducing hole 43, the weight of the protective component 40 is reduced.

[0043] Please refer to the following: Figure 9 As shown, the outer frame 41 includes a first plate 411, a second plate 412, a third plate 413, and a fourth plate 414. The first plate 411 and the second plate 412 are arranged opposite to each other. The third plate 413 and the fourth plate 414 connect the first plate 411 and the second plate 412.

[0044] The first plate member 411 is located at the top of the protective member 40 to form the top surface 405. The second plate member 412 is located at the bottom of the protective member 40 to form the bottom surface 406. The third plate member 413 faces the bumper 20, and the stress surface 401 is provided on the third plate member 413. The fourth plate member 414 faces the anti-collision beam 30, and the assembly surface 402 is provided on the fourth plate member 414.

[0045] The reinforcing rib 42 includes a first reinforcing rib 421 and a second reinforcing rib 422. The first reinforcing rib 421 connects the first plate member 411 and the second plate member 412. The second reinforcing rib 422 connects the third plate member 413 and the fourth plate member 414. The protective member 40 is in a hollow "field" shape, which improves the strength of the protective member 40 and reduces the weight of the protective member 40.

[0046] The protective member 40 is provided with mounting holes 44. The mounting holes 44 extend from the stress surface 401 to the assembly surface 402. Screws 45 are assembled in the mounting holes 44 to fix the protective member 40 to the anti-collision beam 30. Figure 6 The installation position of the screw 45 is shown. The number of the mounting holes 44 can be two. By screwing the protective member 40 to the anti-collision beam 30, the structural strength and the installation efficiency are improved. The protective member 40 can be made of a metal material to further improve the strength.

[0047] Please refer to Figure 10 As shown, the mounting hole 44 includes a first section 441 and a second section 442. The diameter of the first section 441 is larger than that of the second section 442. The first section 441 is arranged close to the assembly surface 402. The second section 442 is arranged close to the stress surface 401. The first section 441 passes through the third plate member 413 and the first reinforcing rib 421. The second section 442 is arranged on the fourth plate member 414. Since the diameter of the second section 442 is larger, it is more convenient for the screw 45 to extend in, further improving the installation efficiency of the protective member 40.

The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the drawings; all modifications, equivalent replacements, improvements, etc. made within the spirit and principle of this application shall be included within the scope of protection of this application.
