Description

Technical Field

[0001] The utility model relates to the technical field of shock absorption, in particular to an intelligent air suspension shock absorber. Background Art

[0002] Automobile chassis suspension shock absorbers are common shock-absorbing devices on vehicles. They can absorb the vibrations generated during driving, reduce the vibration force transmitted to the chassis and frame, and effectively improve driving comfort.

[0003] After searching, the patent document (authorization announcement number CN216111918U) discloses an air spring suspension shock absorbing device, which includes a first mounting frame and a second mounting frame, wherein the first mounting frame is connected to the vehicle frame by bolts, a slide rail is provided on the inner surface of the first mounting frame, a slider is fixedly installed on the outer surface of the second mounting frame, the second mounting frame is slidably connected to the slide rail through the slider, an air spring is fixedly installed between the lower surface of the first mounting frame and the upper surface of the second mounting frame, and a driving wheel group is fixedly installed on the lower surface of the second mounting frame. A first limit block is fixedly installed on the lower surface of the first mounting frame, and a second limit block is fixedly installed on the upper surface of the second mounting frame, and the first limit block matches the second limit block. Both the first limit block and the second limit block are Z-shaped structures. A pressure control valve is fixedly installed on the side surface of the first mounting frame, and the pressure control valve is connected to the air cavity of the air spring.

[0004] When the shock absorbing device is in use, the compressed air is filled in the inner cavity of the air spring to form a compressed air column. As the vibration load increases, the height of the air spring decreases, the volume of the inner cavity decreases, the stiffness of the air spring increases, the effective bearing area of ​​the inner cavity air column increases, and the bearing capacity of the air spring increases; thereby adjusting the internal pressure to obtain different bearing capacities, so it can meet the needs of various loads. However, since the inner surface of the first mounting frame is provided with a slide rail, the outer surface of the second mounting frame is fixedly installed with a slider, and the second mounting frame is slidably connected to the slide rail through the slider, the installation of the first mounting frame and the second mounting frame is only transferred through the slider, and the assembly effect is poor. During the long-term driving of the car, the sliding of the slider on the slide groove is prone to wear. After a certain degree of wear, a large gap will be generated between the slider and the slide groove, and then the slider will be stuck when sliding on the slide groove, which is inconvenient to use.

[0005] To this end, we propose an intelligent air suspension shock absorber to solve the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, the utility model provides an intelligent air suspension shock absorber. By changing the assembly method of the first mounting frame and the second mounting frame, the two can be flexibly connected for a long time. Compared with the assembly method of simply using sliders and slide grooves in the prior art, the improved assembly method of the utility model has the advantages of convenient use and long service life.

[0012] As a preferred technical solution of the utility model, a guide rod is fixedly provided inside the slide groove along its length direction, and the end of the second mounting bracket is sleeved on the guide rod.

[0013] As a preferred technical solution of the utility model, it also includes a lubrication component, which includes a nozzle arranged relatively on the side of the first mounting frame, and one end of the nozzle extends into the slide groove and faces the guide rod, and the end of the nozzle located outside the slide groove is connected to a hose.

When relative displacement occurs between the first mounting frame and the second mounting frame, the air spring works normally. At the same time, the connecting spring will be repeatedly stretched or compressed to achieve buffer protection for the first mounting frame and the second mounting frame. Compared with the simple slide groove and slider assembly method in the prior art, the improved assembly method of the utility model has the advantages of convenient use and long service life.

[0017] 2. By setting the buffer spring, when a position offset occurs between the first mounting bracket and the second mounting bracket, the buffer spring and the connecting spring will be repeatedly stretched and compressed together to achieve good buffer protection.

The adapter can be used to buffer and protect the movement between the first mounting frame 1 and the second mounting frame 2, so that the contact part between the first mounting frame 1 and the second mounting frame 2 can reduce wear and extend the service life of both. Specifically, the adapter includes a first protrusion 5 fixedly arranged on the first mounting frame 1 and a second protrusion 6 fixedly arranged on the second mounting frame 2, and the first protrusion 5 and the second protrusion 6 are both hingedly provided with a connecting rod 7, and the two connecting rods 7 are movably connected at one end close to each other, and the adapter is arranged in two groups, and the two groups of adapters are connected by a connecting spring 8. When relative displacement occurs between the first mounting frame 1 and the second mounting frame 2 , the air spring 3 performs normal shock absorption work. At the same time, the connecting spring 8 is repeatedly stretched or compressed to achieve buffer protection for the first mounting frame 1 and the second mounting frame 2 .

[0029] It should be noted that the air spring 3 in this embodiment is a conventional technical means in the prior art, which plays a normal shock absorbing role.

[0030] Furthermore, in order to prevent the first mounting bracket 1 and the second mounting bracket 2 from working for a long time and causing a high temperature to occur, a temperature sensor can be arranged around the contact area between the first mounting bracket 1 and the second mounting bracket 2. The temperature sensor is electrically connected to the automobile host. When the first mounting bracket 1 and the second mounting bracket 2 work for a long time and cause the surrounding temperature to be high, the temperature sensor can transmit a signal to the automobile host, and the automobile host will issue an alarm reminder, thereby realizing the role of intelligent early warning.

[0031] For the movable connection arrangement between the first mounting frame 1 and the second mounting frame 2, a slide groove 9 may be provided on the side of the first mounting frame 1 in a vertical direction, and the second mounting frame 2 is slidably mounted on the slide groove 9. Meanwhile, a guide rod 14 is fixedly provided inside the slide groove 9 along its length direction, and the end of the second mounting frame 2 is sleeved on the guide rod 14.

[0032] In order to improve the buffering protection effect between the first mounting frame 1 and the second mounting frame 2, a telescopic rod 10 may be provided between the first mounting frame 1 and the second mounting frame 2, and a buffer spring 11 is provided on the outer fixed sleeve of the telescopic rod 10, and both ends of the buffer spring 11 are respectively fixedly connected to the first mounting frame 1 and the second mounting frame 2. When a positional offset occurs between the first mounting frame 1 and the second mounting frame 2, the air spring 3 works, and the buffer spring 11 and the connecting spring 8 are repeatedly stretched and compressed, thereby achieving good buffering protection.

[0033] In order to achieve the detachability between the second mounting frame 2 and the first mounting frame 1, a transverse plate 12 can be provided on the first mounting frame 1, and the transverse plate 12 is fixedly connected to the first mounting frame 1 by fastening bolts 13, and the first protrusion 5, the buffer spring 11 and the telescopic rod 10 are all arranged at the bottom of the transverse plate 12.

During the long-term sliding process of the end of the second mounting frame 2 on the slide groove 9, if there are fine debris such as sand on the sliding path, it will affect the sliding work of the second mounting frame 2. At this time, the nozzle 15 can be controlled to spray lubricating oil on the guide rod 14, so that the sliding of the second mounting frame 2 is smoother, further improving the service life of the first mounting frame 1 and the second mounting frame 2.

[0036] Embodiment three:

Specifically, this embodiment also includes an oil storage tank 17 arranged at the bottom of the slide 9, and the oil storage tank 17 is connected to the slide 9. An outlet is opened at the bottom of the oil storage tank 17, and a piston 18 is sealed at the outlet. The oil storage tank 17 can be used to collect and temporarily store the lubricating oil that slides down the guide rod 14. The subsequent staff opens the piston 18 to discharge the temporarily stored lubricating oil.
