Description

Technical Field

[0001] The utility model relates to the technical field related to automobile manufacturing, in particular to a supporting frame for an automobile front bumper. Background Art

[0002] In the field of modern automobile manufacturing, automobile safety, comfort and overall performance have always been the key directions of research and development and improvement. In terms of automobile safety, with the increase in traffic flow and the increasing complexity of road conditions, the frequency of collision accidents cannot be ignored. The front bumper of the automobile is the first protective structure at the front of the vehicle. Its performance is directly related to the energy absorption and vehicle protection effect during collision.

[0003] Traditional automotive front bumper support frames currently have limitations in design and material usage. Early support frames were relatively simple, often consisting of rigid frames. This design failed to effectively cushion and absorb energy during a collision, causing the impact force to be directly transmitted to other vehicle structures, increasing the risk of damage to internal components and injury to occupants. Furthermore, conventional steel was often used as the primary material for the support frame. While this steel possesses a certain strength, its energy absorption properties are suboptimal, and it cannot effectively dissipate energy through deformation during a collision. Given these limitations, we propose a new automotive front bumper support frame. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a car front bumper support frame, which has the advantages of effectively buffering and absorbing energy during a collision, solving the problem in the existing technology that the bumper support frame cannot effectively buffer and absorb energy.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A car front bumper support frame includes a first anti-collision beam, a cross beam fixedly connected to one side surface of the first anti-collision beam, a second anti-collision beam fixedly connected to one side surface of the cross beam, and a buffer mechanism provided on one side surface of the cross beam for buffering the three support beams;

[0007] The buffer mechanism includes a fixing device and a buffer device, and the fixing device and the buffer device fix and protect the support beam.

[0008] Preferably, the fixing device includes a beam connecting groove, a fixing frame, a rotating threaded column, a fixing disk and a rubber gasket. One side surface of the beam connecting groove is fixedly connected to the fixing frame, one side surface of the fixing frame is rotatably connected to the rotating threaded column, one side surface of the rotating threaded column is fixedly connected to the fixing disk, and one side surface of the fixing disk is fixedly connected to the rubber gasket.

[0009] Preferably, the buffer device includes a spring pad, one side surface of the spring pad is fixedly connected to a spring, one side surface of the spring is fixedly connected to a brittle buffer rod, and one side surface of the brittle buffer rod is fixedly connected to a plastic sponge pad.

[0010] Preferably, two groups of fixing frames are provided on one side of the beam connecting groove, and each group of fixing frames is fixedly connected by two groups of bolts at the top and the bottom.

[0011] Preferably, a cross groove is provided at one end of the rotating threaded column to facilitate the rotation of the rotating threaded column, and a thread is provided on the outer surface of the rotating threaded column. When the rotating threaded column is rotated, the entire threaded column is compressed to fix the crossbeam.

[0012] Preferably, the rubber gasket is made of silicone rubber, the spring pad is made of polyvinyl chloride, the brittle buffer rod is made of silicon carbide ceramic, and the plastic sponge pad is made of polyurethane sponge.

[0013] Preferably, four groups of springs are fixedly connected to the surface of one side of the crossbeam connecting groove and are symmetrically arranged about the perpendicular midline of the crossbeam connecting groove. The plastic sponge pad can absorb part of the kinetic energy for the brittle buffer rod to prevent the brittle buffer rod from accidentally breaking when the car is not subjected to a large impact.

[0014] Compared with the prior art, the present invention provides a car front bumper support frame with the following beneficial effects:

[0015] 1. The front bumper support frame is equipped with a buffer mechanism, which can effectively buffer and absorb energy when a collision occurs. When the impact force is transmitted to the support frame, the spring first undergoes elastic deformation, converting part of the kinetic energy into elastic potential energy. The number and symmetrical distribution of the springs ensure the uniformity of force and the stability of buffering. The brittle buffer rod is made of silicon carbide ceramic, which has a certain hardness and brittleness and can consume a lot of energy by breaking under a large impact force. The plastic sponge pad made of polyurethane sponge material set in front of the brittle buffer rod can absorb part of the kinetic energy in small impacts during daily driving or when it does not reach the level of large impact, protecting the brittle buffer rod from accidental breakage. It also provides a staged and multi-level buffering mechanism for the overall energy absorption process, reducing the possibility of the impact force generated by the collision being directly transmitted to other structures of the vehicle body, thereby reducing the risk of damage to internal components of the vehicle and injury to people inside the vehicle.

[0016] 2. The front bumper support frame features a fixing device. This design utilizes two sets of fixing frames secured to one side of the crossbeam connection slot with bolts, firmly connecting the buffer mechanism to the crossbeam and ensuring structural stability. The two sets of bolts on each fixing frame, one above and one below, further enhance the connection's reliability, preventing loosening during collisions or daily use. A cross-slot at one end of the threaded post facilitates operation, and the threads on its outer surface compress inward during rotation, allowing the fixing plate to fit tightly against the crossbeam. The silicone rubber gasket increases friction and provides a cushioning effect, preventing damage from rigid contact. It also reduces loosening due to vibration, ensuring the structural integrity and connection reliability of the entire support frame during vehicle operation and collisions.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-4 A car front bumper support frame includes a first anti-collision beam 1, a cross beam 2 is fixedly connected to one side surface of the first anti-collision beam 1, a second anti-collision beam 3 is fixedly connected to one side surface of the cross beam 2, and a buffer mechanism 4 with a buffering effect on the three support beams is provided on one side surface of the cross beam 2. The buffer mechanism 4 includes a fixing device and a buffer device.

[0024] In this embodiment, the fixing device includes a crossbeam connecting groove 401, a fixing frame 402, a rotating threaded post 403, a fixing plate 404, and a rubber gasket 405. The crossbeam connecting groove 401 is fixedly connected to the fixing frame 402 on one side, the rotating threaded post 403 is rotatably connected to the fixing frame 402 on one side, the rotating threaded post 403 is fixedly connected to the fixing plate 404 on one side, and the fixing plate 404 is fixedly connected to the rubber gasket 405 on one side. Due to the arrangement of the crossbeam connecting groove 401, the fixing frame 402, the rotating threaded post 403, the fixing plate 404, and the rubber gasket 405, during use, the cross groove on the rotating threaded post 403 facilitates rotation using a tool, allowing the installer to quickly secure the buffer mechanism to the crossbeam. The threaded design allows for precise adjustment of the position of the fixing plate 404 to accommodate a variety of situations and facilitates installation. For stability, the crossbeam connection slot 401 and the fixing frame 402 are tightly connected, providing a stable installation foundation for the buffer mechanism. The fixing plate 404 has a large contact area with the buffer mechanism, ensuring a secure connection. The elasticity of the rubber gasket 405 absorbs the impact of vibrations and minor collisions, providing a buffering and protective effect, reducing damage to the fixture and crossbeam, while also preventing rigid friction between components.

[0025] Furthermore, the buffer device includes a spring pad 406, one side of which is fixedly connected to a spring 407. One side of the spring 407 is fixedly connected to a brittle buffer rod 408. One side of the brittle buffer rod 408 is fixedly connected to a plastic sponge pad 409. The arrangement of the spring pad 406 and the brittle buffer rod 408 allows the spring pad 406 to provide support for the spring 407 during use. When impacted, the spring 407 elastically deforms, converting kinetic energy into elastic potential energy. This effectively buffers small collisions, such as those caused by low-speed collisions or collisions with small obstacles, reducing bumper deformation and allowing for repeated use. When the collision exceeds the buffering limit of the spring 407, the brittle buffer rod 408 breaks and absorbs energy, achieving graded energy absorption to cope with different collisions. In terms of protection, the spring pad 406 and spring 407 can reduce the impact on the vehicle body structure, while the brittle buffer rod 408 prevents energy from impacting important components. The spring pad 406 protects the spring 407, and the plastic sponge pad 409 protects the brittle buffer rod 408.

[0026] Furthermore, two groups of fixing frames 402 are provided on one side of the crossbeam connecting groove 401, and each group of fixing frames 402 is fixedly connected by two groups of bolts on the upper and lower sides. Through the setting of the fixing frames 402, when in use, two groups of fixing frames 402 are provided on one side of the crossbeam connecting groove 401, and each group is fixedly connected by two groups of bolts on the upper and lower sides. This design forms a multi-point stable connection structure, which can effectively resist forces from all directions. When the car is driving, whether it is the vibration of normal driving or the impact force generated by the collision, the firmness of the connection between the buffer mechanism and the crossbeam can be guaranteed to prevent the buffer mechanism from shifting or loosening. At the same time, multiple groups of bolt connections make the fixing frame 402 not easily damaged due to fatigue during long-term use, which greatly improves the reliability and durability of the entire supporting skeleton structure and ensures the safety performance of the car.

[0027] Furthermore, a cross slot is provided at one end of the rotating threaded column 403 to facilitate the rotation of the rotating threaded column 403. A thread is provided on the outer surface of the rotating threaded column 403. When the rotating threaded column 403 is rotated, the threaded column as a whole is compressed to fix the crossbeam 2. By setting the rotating threaded column 403, when in use, the cross slot at one end is convenient for rotation using tools such as a screwdriver, which reduces the installation difficulty and operation complexity and improves the installation efficiency. In terms of the fixing function, the thread design on its outer surface is ingenious. When rotating, the threaded column as a whole is compressed, which can accurately and tightly fix the buffer mechanism to the crossbeam 2. This fixing method is not only firm and reliable, but can also effectively prevent loosening due to vibration and bumps during driving of the car. In addition, when there are differences in different car models or crossbeam sizes, it can also be properly adjusted by rotating the threaded column, thereby enhancing the adaptability of the entire support frame.

[0028] Furthermore, the rubber gasket 405 is made of silicone rubber, the spring pad 406 is made of polyvinyl chloride, the brittle buffer rod 408 is made of silicon carbide ceramic, and the plastic sponge pad 409 is made of polyurethane sponge. Through the arrangement of the rubber gasket 405, the spring pad 406, the brittle buffer rod 408 and the plastic sponge pad 409, when in use, the rubber gasket 405 is made of silicone rubber, which has good elasticity and flexibility, can effectively buffer vibration and impact force, protect the fixing device and the crossbeam connection part, and reduce wear. The spring pad 406 is made of polyvinyl chloride, provides stable support for the spring 407, and has a certain buffering capacity. The brittle buffer rod 408 is made of silicon carbide ceramic, which has high hardness and appropriate brittleness. It can absorb a large amount of energy by breaking in a large collision to protect the vehicle body. The plastic sponge pad 409 is a polyurethane sponge, which can absorb daily small impacts and small collision energy to prevent the brittle buffer rod 408 from accidentally breaking, and can also play a certain blocking role on fragments, thereby improving overall safety.

[0029] Furthermore, four groups of springs 407 are fixedly connected to the surface of one side of the crossbeam connecting groove 401, and are symmetrically arranged about the median perpendicular of the crossbeam connecting groove 401. The plastic sponge pad 409 can absorb part of the kinetic energy for the brittle buffer rod 408 to prevent the brittle buffer rod 408 from accidentally breaking when the car is not subjected to a large impact. Through the arrangement of the springs 407, the buffering effect can be enhanced during use. Four groups of springs 407 are fixedly connected to the surface of one side of the crossbeam connecting groove 401, and are symmetrically arranged about the median perpendicular. This symmetrical distribution can evenly disperse the impact force and ensure the stability of the buffering. When a collision occurs, the springs 407 can effectively absorb and buffer energy and reduce the impact on the car body and other components. In small collisions, the elastic deformation of the springs 407 can prevent the impact force from being directly transmitted to the brittle buffer rod 408, thereby protecting the brittle buffer rod 408. Moreover, the arrangement of the four groups of springs 407 increases the overall buffering capacity, so that the front bumper support frame of the car can cope with a variety of collision conditions of different degrees.

[0030] During use, minor impacts from road bumps and other factors are transmitted to the support frame. The spring 407 pad 406 and spring 407 in the buffer mechanism 4 begin to function. The spring 407 pad 406 utilizes the elasticity of its polyvinyl chloride material to initially cushion the vibration, while the spring 407 elastically deforms under minor impacts, converting the vibration energy into stored elastic potential energy. The symmetrically arranged springs 407 evenly distribute the impact force, maintaining structural stability. Simultaneously, the polyurethane sponge pad 409 absorbs minor impact energy. Its porous structure dissipates energy through deformation of the pore walls, protecting the brittle buffer rod 408. The rubber gasket 405 of the fixing device also buffers and isolates vibrations from the vehicle body, preventing rigid contact issues. When a minor collision occurs, the impact force increases. The deformation of the spring 407 pad 406 and spring 407 intensifies, and the spring 407 absorbs a large amount of the collision energy and converts it into elastic potential energy. Its elastic restoring force slows the deformation of the bumper. The plastic sponge pad 409 further compresses, participating in energy absorption and preventing premature breakage of the brittle buffer rod 408. The fixing device ensures that the buffer mechanism 4 is firmly connected to the crossbeam 2, and the rubber gasket 405 further buffers the collision force and prevents loosening. In the event of a large collision, the spring 407 is first extremely compressed, absorbing and buffering part of the energy until it reaches its limit. Subsequently, the brittle buffer rod 408 made of silicon carbide ceramic plays a key role, breaking as designed under the huge impact force, absorbing a large amount of energy to overcome the breakage of chemical bonds and generate new surfaces. The plastic sponge pad 409 absorbs part of the energy in the early stage and blocks fragments when the brittle buffer rod 408 breaks. The fixing device withstands huge forces with its solid structure, maintains the connection between the buffer mechanism 4 and the crossbeam 2, and ensures that the entire support frame effectively disperses and absorbs collision energy, reducing damage to the vehicle body and personnel. Through these mechanisms, this support frame effectively protects the car under different degrees of collision.
