Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.
In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," "engaged," "hinged," and the like are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral part; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other suitable relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
Referring to fig. 1, as an embodiment of the present invention, the rear bumper includes a first collision prevention section 110 and a second collision prevention section 120. Wherein, first anticollision section 110 is the arc structure, and sunken side and car afterbody looks adaptation are fixed in the car afterbody. The number of the second anti-collision sections 120 is two, and the two second anti-collision sections are symmetrically fixed at two ends of the first anti-collision section 110. The second anti-collision section 120 is also of an arc-shaped structure, and the concave side of the second anti-collision section is matched with the tail gas discharge port at the tail part of the automobile and is attached to the rear side of the tail gas discharge port. The second anti-collision section 120 is provided with an exhaust hole 121 opposite to the exhaust port. The convex side of the second collision avoidance section 120 protrudes a predetermined distance from the convex side of the first collision avoidance section 110.
In this embodiment, the first impact segment 110 is secured to the rear of the vehicle. When the automobile tail is impacted, impact force can be effectively absorbed through deformation, so that the automobile tail is protected, and the possibility of damage to automobile tail parts is reduced. The second anti-collision section 120 is fixed to the rear side of the exhaust gas discharge port at the rear of the vehicle. When the exhaust gas discharge port is impacted, impact force can be effectively absorbed through deformation, and the possibility of damage to the exhaust gas discharge port is effectively reduced. Wherein, all design first anticollision section 110 and second anticollision section 120 for arc or domes, relative linear type structure, anti deformability is stronger when suffering the front impact for rear bumper's energy-absorbing characteristic is stronger, has both improved the crashworthiness of automobile rear portion effectively, has improved the security of auttombilism again. Also, the convex side of the second collision avoidance section 120 protrudes a predetermined distance from the convex side of the first collision avoidance section 110. Specifically, the preset distance may be 10-30 cm. Thus, when the rear portion of the automobile is subjected to a relatively violent frontal impact, the second anti-collision section 120 can primarily absorb the impact force generated by the impact, and the second anti-collision section 120 can absorb the impact force generated by the impact again. On the overall structure, the energy-absorbing characteristic of the rear bumper is greatly enhanced.
In a specific embodiment of the present invention, the rear bumper further includes a third collision prevention section 130. The number of the third anti-collision sections 130 is two, wherein one of the third anti-collision sections 130 is fixedly connected with one end of one of the second anti-collision sections 120 away from the first anti-collision section 110, and the other third anti-collision section 130 is fixedly connected with one end of the other second anti-collision section 120 away from the first anti-collision section 110. Two anticollision sections are linear structure, and the inboard both sides that are fixed in the automobile afterbody respectively. Therefore, the possibility of damaging the two sides of the tail of the automobile is effectively reduced. When two sides of the tail of the automobile are impacted, the third impact prevention section 130 can effectively absorb impact force, so that the impact resistance of the two sides of the tail of the automobile and the driving safety are effectively improved. Functionality is increased over conventional rear bumpers.
In one embodiment of the present invention, the rear bumper further includes a fixing ring 140 and a reinforcing rib 150. Wherein, solid fixed ring 140 is two, all overlaps the middle part of locating first anticollision section 110, gu fixed ring 140 and automobile tail fixed connection. The first anti-collision section 110 can be fixed at the tail of the automobile through the fixing ring 140, so that the first anti-collision section 110 and the tail of the automobile can be conveniently and quickly detached and installed. Meanwhile, the fixing ring 140 can play a role of hard support for the first anti-collision section 110, so that the deformation resistance of the first anti-collision section 110 is improved, and the energy absorption characteristic is enhanced. The reinforcing ribs 150 are fixed to the rear of the automobile, and one end of each reinforcing rib is fixedly connected with the outer wall of the fixing ring 140. So, improved first anticollision section 110 and car end connection's stability effectively, and then improved rear bumper and car end connection's steadiness effectively for rear bumper is difficult for the dislocation when suffering the striking.
In a specific embodiment of the present invention, the connecting position of the first anti-collision section 110 and the second anti-collision section 120 is chamfered, so that the stress of the connecting position of the first anti-collision section 110 and the second anti-collision section 120 is not concentrated when the rear bumper is impacted, thereby effectively preventing the possibility of fracture of the connecting position. In addition, the first anti-collision section 110, the second anti-collision section 120 and the third anti-collision section 130 are all made of stainless steel, so that the anti-collision performance of the rear bumper is effectively improved. Furthermore, the first, second and third impact prevention sections 110, 120, 130 are integrally formed. Therefore, the processing steps are effectively reduced, and the manufacturing efficiency is improved. Meanwhile, the rear bumper is convenient to disassemble and install, and the assembly complexity and the positioning and installing difficulty of the rear bumper are effectively reduced.
Referring to fig. 1, 2, 3 and 4, the present invention also provides an automobile having a rear bumper, including the rear bumper provided above, further including an exhaust pipe throat 200 and a protection net 300. Wherein, one end of the exhaust pipe tail throat 200 is fixed in the exhaust vent through the mounting frame 400, and the other end is located in the exhaust vent 121 and has an open structure. Exhaust gas generated from the automobile is discharged into the exhaust hole 121 through the open end of the exhaust pipe throat 200, and is discharged from the outlet of the exhaust hole 121. The exhaust holes 121 compensate for a partial length of the exhaust pipe throat 200, and prevent the exhaust pipe throat 200 from interfering with the rear bumper when the rear bumper is installed, thereby facilitating the installation of the rear bumper. The protective net 300 is fixed in the exhaust hole 121, and a relief hole 310 is formed in the middle of the protective net for the open end of the exhaust pipe tail throat 200 to pass through. The protective net 300 can effectively support the open end of the exhaust pipe tail throat 200, and can prevent sundries with large external volume from entering the exhaust holes 121, thereby effectively reducing the maintenance cost and simultaneously ensuring that the whole body is more attractive after assembly. Specifically, the edge of the protection net 300 and the inner wall of the exhaust hole 121 are fixedly connected using a self-tapping screw, so that the protection net 300 is convenient to detach and install. Wherein, mounting bracket 400 is wholly "omega" type structure, and threaded hole has all been seted up on its both feet limit, uses hexagon flange face bolt and reed nut fixed connection mounting bracket 400 and exhaust emission port through the screw hole. Thus, the positional stability of the exhaust pipe tail throat 200 is high.
