Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile radiator, more particularly to an automobile radiator with damping device. BACKGROUND

[0002] As the core component of engine cooling system, the stability and structural reliability of automobile radiator are directly related to the running safety and performance of the whole vehicle. In the prior art, the automobile radiator is usually directly installed on the vehicle frame through rigid support or simple rubber pad. Although this traditional installation method is simple in structure and low in cost, it has significant defects.

[0003] Due to the lack of a truly effective damping and buffering mechanism, the severe vibration and impact energy transmitted from the wheels to the vehicle frame during driving, especially when passing through bumpy roads, speed bumps or rugged terrain, will be almost directly transmitted to the radiator assembly without attenuation. This continuous and unattenuated mechanical stress can easily cause the thin-walled copper pipes of the radiator core and the welds connecting them to the upper and lower liquid guide shells to crack due to fatigue, resulting in coolant leakage. At the same time, it can also cause the radiator fins to twist and deform, thereby reducing the heat dissipation efficiency. More seriously, in a long-term, high-frequency vibration environment, this rigid connection can accelerate the metal fatigue of the entire radiator structure, eventually leading to its early failure. Although some improved solutions attempt to introduce simple rubber bushings, their damping effect is limited, and the rubber material is prone to aging and failure in high-temperature and oil-contaminated environments, thus failing to provide durable and reliable protection.

[0027] With reference to Figures 1 to 4 The present application provides a car radiator with a damping device, comprising an upper liquid guide shell 1 and a lower liquid guide shell 2, the upper liquid guide shell 1 and the lower liquid guide shell 2 are fixedly connected and connected through a copper pipe 3, the upper liquid guide shell 1 and the lower liquid guide shell 2 are also provided with a support frame 4 and a heat dissipation fin 5, the support frame 4 and the heat dissipation fin 5 are both fixedly installed on the surface of the copper pipe 3, the heat dissipation fin 5 is provided with a receiving frame 6 and a bridge frame 7 on both sides, the bridge frame 7 is fixedly installed on the car frame, the receiving frame 6 is welded on the support frame 4, a buffer mechanism 8 is arranged between the receiving frame 6 and the bridge frame 7, the buffer mechanism 8 is used to decompose and dissipate the vibration and impact energy transmitted from the car frame through the bridge frame 7 during the driving of the car, and to reduce the vibration intensity transmitted to the core part of the radiator. By introducing an independent buffer mechanism 8 between the radiator and the frame, the rigid connection relationship between the radiator and the frame is fundamentally changed, laying a structural foundation for subsequent vibration isolation, and the core purpose is to actively intervene and attenuate the transmission path of vibration energy, thereby directly protecting the precise and vulnerable heat dissipation core composed of the copper pipe 3 and the heat dissipation fin 5, and effectively avoiding the risk of cracking and leakage caused by long-term vibration.

[0028] The bridge frame 7 is provided with two, the receiving frame 6 is provided with four, the buffer mechanism 8 is provided with four, and the heat dissipation fin 5 is provided with two receiving frames 6 on each side, and the buffer mechanism 8 is arranged between the two ends of the bridge frame 7 and the receiving frame 6. The symmetrical distributed layout of two bridge frames 7, four receiving frames 6 and four buffer mechanisms 8 forms multiple independent damping support points on both sides of the radiator, which can evenly disperse and bear complex stresses from different directions, avoid local stress concentration, improve the support stability and balance of the radiator under dynamic working conditions, and ensure the overall consistency of the damping effect.

[0029] With reference to Figures 1 to 8The buffer mechanism 8 includes a mounting plate 81, a stabilizing frame 82, a connecting frame 83 and a connecting rod 84, the mounting plate 81 is provided with a bolt one 61 and a nut one 62 between the receiving frame 6, and the bolt one 61 and the nut one 62 are used to fix the mounting plate 81 and the receiving frame 6. The buffer mechanism 8 adopts a modular design, and is reliably connected with the receiving frame 6 through bolts and nuts, which not only makes the installation and later maintenance and replacement more convenient and efficient, but also clearly separates the buffer function unit and the radiator main body structure, forms an independent and optimized subsystem, and improves the maintainability and universality of the whole design.

[0030] The bridge 7 is welded with a connecting frame 71 at both ends, the connecting frame 71 is provided with a bolt two 72, a nut two 73 and a bolt three 74 between the stabilizing frame 82, the bolt two 72 and the nut two 73 are used to connect and fix the connecting frame 71 and the stabilizing frame 82, the stabilizing frame 82 is provided with a threaded groove 821, and one end of the bolt three 74 penetrates through the connecting frame 71 and is threadedly connected into the threaded groove 821. Through the multiple fastening modes of the connecting frame 71 and the bolt two 72, the nut two 73 and the bolt three 74, especially the cooperation of the bolt three 74 and the special threaded groove 821 on the stabilizing frame 82, the bridge 7 and the buffer mechanism 8 are firmly and stably connected, the connection point is prevented from loosening in a continuous vibration environment, the vibration energy can be reliably introduced into the buffer mechanism 8, and the shear resistance and torsion resistance of the whole connection structure are enhanced. In addition, the threaded connection design is also convenient for replacement and maintenance.

[0031] The stabilizing frame 82 is fixedly connected with a fixed shaft 822 and a positioning shaft 823, and each stabilizing frame 82 is provided with two fixed shafts 822 and two positioning shafts 823, one side of the mounting plate 81 is fixedly connected with an extension frame 86, the extension frame 86 is fixedly connected with a stabilizing shaft 861 and an extension shaft 862, and each extension frame 86 is provided with two stabilizing shafts 861 and two extension shafts 862. A plurality of fixed shafts 822, positioning shafts 823, stabilizing shafts 861 and extension shafts 862 are arranged on the stabilizing frame 82 and the extension frame 86 respectively, which provides a plurality of accurate fulcrums for the subsequent hinging of the connecting frame 83 and the connecting rod 84. This multi-shaft layout constitutes a stable kinematic pair foundation, so that the vibration energy can be dispersed to multiple transmission paths, provides necessary structural conditions for realizing multi-link buffer movement, and is the key to realizing efficient energy conversion and dissipation.

[0032] The connecting frame 83 is in H-shaped structure, the connecting frame 83 is used for connecting the fixed shaft 822 and the stabilizing shaft 861, the connecting frame 83 is rotatably installed on the surface of the fixed shaft 822, and the connecting frame 83 is rotatably installed on the surface of the stabilizing shaft 861. The connecting frame 83 in the H-shaped structure is rotatably connected with the shafts on the stable frame 82 and the extension frame 86, and a part of an efficient four-bar linkage structure is substantially formed, the linear impact and vibration from the vehicle frame can be converted into the rotary motion of the connecting frame 83, which is a preliminary energy buffering and motion form conversion process, and the high-frequency small-amplitude vibration can be filtered, and the impact force directly acting on the radiator can be reduced.

[0033] The connecting rod 84 is used for connecting the positioning shaft 823 and the extension shaft 862, one end of the connecting rod 84 is rotatably installed on the surface of the positioning shaft 823, and the other end of the connecting rod 84 is rotatably installed on the surface of the extension shaft 862. The connecting rod 84 cooperates with the connecting frame 83 to form a complete four-bar linkage buffering system with determined motion constraints, the relative motion trajectory between the stable frame 82 and the extension frame 86 can be accurately guided, and the impact energy can be further converted into the rotary inertia of the rod, so that secondary buffering is realized, and the adaptability and stability of the whole system to large-amplitude vibration are improved.

[0034] The limiting shaft 824 is fixedly connected to the stable frame 82, the movable shaft 863 is fixedly connected to the extension frame 86, the shock absorber 85 is arranged between the limiting shaft 824 and the movable shaft 863, the sleeve ring two 852 is fixedly connected to the output end of the shock absorber 85, the sleeve ring one 851 is fixedly connected to the outer cylinder of the shock absorber 85, the sleeve ring one 851 is rotatably installed on the surface of the limiting shaft 824, and the sleeve ring two 852 is rotatably installed on the surface of the movable shaft 863. The shock absorber 85 is rotatably installed on the limiting shaft 824 and the movable shaft 863 through the sleeve rings at both ends, so that the shock absorber 85 can freely stretch and contract with the movement of the connecting rod structure and will not be damaged by an additional bending moment, when the piston rod of the shock absorber 85 is driven to move by vibration, a great damping force is generated in the damping medium in the shock absorber 85, mechanical kinetic energy is finally converted into heat energy and dissipated into the air, so that the vibration hazard is completely eliminated, and the radiator is directly and effectively protected.

[0035] The working principle of the present application is as follows: when the automobile is driven on the uneven road and vibration and impact are generated, the vibration energy is first transmitted to the bridge frame 7 connected with the vehicle frame, then transmitted to the stable frame 82 of the buffering mechanism 8 through the connecting frame 71 welded at both ends of the bridge frame 7, and the vibration energy is decomposed into two main transmission paths.

[0036] One of the paths, through the four-bar linkage structure composed of the connecting frame 83 and the connecting rod 84, the four-bar linkage structure is hinged together by the two end rotating connection points, i.e. the fixed shaft 822 and the stable shaft 861, the positioning shaft 823 and the extension shaft 862, so as to convert the linear impact into the relative rotation of the connecting frame 83 and the connecting rod 84, which is a preliminary energy buffering and motion form conversion process.

[0037] The second path is achieved by relying on the special shock absorber 85 mounted between the limiting shaft 824 on the stable frame 82 and the movable shaft 863 on the extension frame 86. When the vibration causes the relative displacement of the stable frame 82 and the extension frame 86, the piston rod of the shock absorber 85 is driven to extend and retract, and the damping medium inside the shock absorber 85 generates a huge damping force when passing through the precise valve system, so as to convert the mechanical kinetic energy into heat energy and dissipate it into the air. Through the above mechanical linkage and hydraulic damping, most of the severe vibration from the vehicle frame is effectively inhibited and absorbed before reaching the core components of the precise and fragile radiator, such as the copper pipe 3 and the heat sink 5, so as to realize the flexible support and dynamic protection of the radiator, and improve the structural safety and service life of the radiator under complex working conditions.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the present application, which should be covered in the scope of the claims of the present application.
