Traditional mechanical suspensions, based on coil springs and fixed damping shock absorbers, are simple in structure and low in cost. However, because their suspension parameters are fixed, they are difficult to adapt to complex and changing road conditions and driving situations. For example, when driving on bumpy roads, mechanical suspensions cannot quickly dampen high-frequency vibrations, resulting in a poor driving experience. Furthermore, during high-speed cornering or emergency braking, they cannot provide sufficient support, severely impacting vehicle handling stability. Therefore, developing an electronically controlled air suspension height-adjustable control device that can achieve precise height adjustment, efficient shock absorption, and significantly improve vehicle driving performance has become an urgent need in automotive technology development.

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides an electronically controlled air suspension height adjustable control device, which includes: a bracket 1, a support plate 3 fixedly connected to the upper surface of the bracket 1, the support plate 3 being located on the left and right sides of the bracket 1, a base plate 4 fixedly connected to the upper surface of the support plate 3, a damper 12 fixedly connected to the upper surface of the base plate 4, a buffer spring 13 fixedly connected to the upper surface of the base plate 4, the damper 12 being located at the center of the buffer spring 13, a top plate 5 fixedly connected to the upper ends of the damper 12 and the buffer spring 13, a lower base 14 fixedly connected to the upper surface of the base plate 4, an airbag 7 fixedly connected to the upper surface of the lower base 14, the damper 12 and the buffer spring 13 being located between the airbag 7, an upper top seat 15 fixedly connected to the upper surface of the airbag 7, and a limit groove being provided on the upper surface of the base plate 4 and the lower surface of the top plate 5, with the lower base 14 and the upper top seat 15 being located inside the limit groove.

[0022] Specifically, bracket 1 serves as the basic support structure for the entire device, bearing the weight of other components and ensuring the stability of the device. Support plate 3 is fixed to the upper surface of bracket 1 and located on the left and right sides, providing support for base plate 4 and providing installation and accommodating space for delivery pipe 10, thus increasing the overall structural strength of the device. Base plate 4 is fixed to the upper surface of support plate 3, providing an installation platform for components such as airbag 7, damper 12, and buffer spring 13. The limiting groove on its upper surface limits the lower base 14, ensuring the accuracy of the airbag 7 installation position. At the same time, delivery pipe 10 passes through base plate 4, facilitating the delivery of compressed air. Top plate 5 is fixedly connected to the upper ends of damper 12 and buffer spring 13, and the limiting groove on its lower surface limits the upper top seat 15. When airbag 7 is inflated or deflated, top plate 5 will move up and down with the expansion or contraction of airbag 7. The roof plate 5 is installed at the bottom of the vehicle to adjust the vehicle height. The airbag 7, as the core component of the air spring, changes its volume and elasticity by inflating and deflating to adjust the vehicle height. When compressed air is inflated, the airbag 7 expands and the vehicle rises; when air is expelled, the airbag 7 contracts and the vehicle lowers. The damper 12, installed on the floor plate 4, is fixed to the upper surface of the floor plate 4 and located at the center of the buffer spring 13. Its upper end is fixedly connected to the roof plate 5. It is used to dampen vibration and improve ride comfort. When the vehicle is impacted by the road surface during driving, the damper 12 can absorb and dissipate energy and reduce the vibration amplitude of the vehicle body. The buffer spring 13 is fixed to the upper surface of the floor plate 4, and its upper end is fixedly connected to the roof plate 5. It works in conjunction with the damper 12 to bear and transmit vertical loads and mitigate and suppress the impact caused by uneven road surfaces.

[0023] Reference Figure 1 , Figure 3 and Figure 4 An inflation mechanism 8 is provided on the upper surface of the support 1. A positioning groove is provided on the upper surface of the support 1. The inflation mechanism 8 is installed inside the positioning groove. A delivery pipe 10 is fixedly connected to the output end of the inflation mechanism 8. The end of the delivery pipe 10 away from the inflation mechanism 8 passes through the lower base 14. The delivery pipe 10 passes through the base plate 4. The airbag 7 is connected to the inflation mechanism 8 through the delivery pipe 10. The delivery pipe 10 is located directly below the base plate 4. A height adjustment valve 9 is provided on the side surface of the delivery pipe 10. A solenoid valve 11 is provided on the side surface of the delivery pipe 10. A support rod 6 is fixedly connected to the upper surface of the base plate 4. The support rod 6 is located directly below the top plate 5 and is evenly distributed at the four corners of the base plate 4. Wheels 2 are rotatably connected to the left and right ends of the support 1.

[0024] Specifically, bracket 1 serves as the basic support structure for the entire device, bearing other components and ensuring the stability of the device. The positioning groove on its upper surface is used to install the inflation mechanism 8, ensuring the accurate installation position of the inflation mechanism 8. Simultaneously, the inflation mechanism 8 provides compressed air to the airbag 7, serving as the power source for the entire inflation process. One end of the delivery pipe 10 is fixedly connected to the output end of the inflation mechanism 8, and the other end passes through the lower base 14 and the base plate 4, connecting to the airbag 7. This is the channel through which compressed air is delivered from the inflation mechanism 8 to the airbag 7. A height adjustment valve 9 is installed on the side surface of the delivery pipe 10, automatically adjusting the amount of air entering or exiting the airbag 7 according to the vehicle height and the preset target height. When the vehicle height is lower than the target value, the control system opens the inflation channel through the height adjustment valve 9, allowing air to enter or exit the airbag 7. Compressed air enters the airbag 7. When the vehicle height is higher than the target value, the control system opens the venting passage through the height adjustment valve 9 to expel the air from the airbag 7. The solenoid valve 11 is installed on the side surface of the delivery pipe 10 and receives electrical signals from the control unit to quickly and accurately control the inflation and deflation of the air spring. For example, when an emergency adjustment of the vehicle height is required, the solenoid valve 11 can respond quickly and change the flow path of the compressed air. The wheels 2 are installed at the left and right ends of the bracket 1 and are the actuators for vehicle movement, enabling the vehicle to move. The support rod 6 is fixed to the upper surface of the base plate 4 and located directly below the top plate 5. It is evenly distributed at the four corners of the base plate 4 to provide support for the top plate 5, preventing the top plate 5 from damaging the airbag 7 when it is compressed, and enhancing the overall structural stability of the device.

[0025] Working principle: The bracket 1 serves as the basic support for the device, bearing the components and ensuring stability. The positioning slot of the bracket 1 is used to install the inflation mechanism 8, which provides power for inflating the airbag 7. The wheels 2 are installed at both ends of the bracket 1 to move the vehicle. The delivery pipe 10 connects the inflation mechanism 8 and the airbag 7 to deliver compressed air. The height adjustment valve 9 automatically adjusts the air intake and exhaust volume of the airbag 7 according to the vehicle height and target value. When the vehicle is low, the inflation channel is opened; when it is high, the exhaust channel is opened. The solenoid valve 11 receives the control unit signal and quickly controls the inflation and deflation. In case of emergency adjustment, it changes the airflow path. The inflation and deflation of the airbag 7 changes its volume and elasticity to adjust the vehicle height. The damper 12 works with the buffer spring 13 to bear the transmitted load, dampen vibration, and improve comfort. The support rod 6 provides support for the roof plate 5, enhances the stability of the device, and prevents the roof plate 5 from being damaged by the compression of the airbag 7.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
