Description

Technical Field

[0001] This invention relates to the field of new energy pure electric vehicle technology, and in particular to a suspension damping mechanism for a new energy pure electric driven vehicle. Background Technology

[0002] With the rapid development of new energy pure electric vehicles, the requirements for driving comfort, handling stability, and component compatibility are constantly increasing. As a core component ensuring vehicle driving performance, the rationality of the suspension damping mechanism and the integrity of its function directly affect the user experience and driving safety. Currently, many existing pure electric vehicle suspension damping mechanisms suffer from problems such as complex structure, high production cost, and inconvenient installation. Moreover, most shock absorbers have fixed damping forces and cannot adaptively adjust according to different driving scenarios such as smooth roads and bumpy roads, making it difficult for vehicles to balance comfort and stability under different road conditions. Some adjustable damping shock absorber mechanisms use magnetorheological fluid or solenoid valve structures, which have drawbacks such as high cost, poor reliability, and inconvenient maintenance. Furthermore, their attitude adjustment precision is insufficient, and when the vehicle is turning, climbing hills, or carrying heavy loads, it cannot quickly and accurately adjust the body attitude, which can easily lead to problems such as body roll and excessive sagging. Meanwhile, the shock-absorbing components of existing mechanisms lack effective protective structures, making them susceptible to corrosion from dust and impurities, thus shortening their service life. Furthermore, most adjustment mechanisms have slow response speeds, making it difficult to adapt to the driving characteristics of pure electric vehicles and failing to meet users' high-quality demands for vehicle driving comfort and safety. Therefore, there is an urgent need for a new energy pure electric drive vehicle suspension shock-absorbing mechanism with a reasonable structure, precise adjustment, and strong adaptability to solve the above problems.

[0030] The openings of the small hole 734 on both the upper and lower sides are flared.

[0031] like Figure 6 As shown, the adjustable flow rate device 735 includes a second motor 7351, a valve body 7352, a sliding hole 7353, a second screw 7354, a valve core 7355, an outer conical surface 7356, an inner conical hole 7357, a first connecting hole 7358, a second connecting hole 7359, and a conveying hole 73510. The valve body 7352 is externally fixedly connected to the upper interior of the outer casing 71. The second motor 7351 is externally fixedly connected to the left side of the valve body 7352.

[0032] Among them, the second motor 7351 is a servo motor or a stepper motor.

[0033] The invention is used as follows: The invention has a reasonable and simple structure, low production cost, convenient installation, and complete functions. When the vehicle is traveling on a flat road, the frame 1 serves as the mounting base for the entire mechanism. The connecting slots 10 on its left and right sides provide fixed support for mounting shaft 1 3 and mounting shaft 2 9. The connecting slots 10 maintain a fixed connection with mounting shaft 1 3 and mounting shaft 2 9, with no relative displacement. The two connecting seats 6 are in a horizontal and stable state. The connecting shaft 1 5 on the upper side of the connecting seat 6 is movably connected to one side of the upper connecting rod 4, and the connecting shaft 2 11 on the lower side of the connecting seat 6 is movably connected to one side of the lower connecting rod 8. The other side of the upper connecting rod 4 is movably connected to mounting shaft 1 3, and the other side of the lower connecting rod 8 is movably connected to mounting shaft 2 9. Both the upper connecting rod 4 and the lower connecting rod 8 are in a horizontal and stable state. Under light stress, there is no obvious swaying. The connecting seat 6 supports the wheel (connecting seat 6 is used to connect the wheel). Here, the adjustable shock absorber 7 is in its initial extension / retraction state. The connecting hole 72 on the upper side of its outer shell 71 is hinged to one side of the connecting arm 27 in the adjustment mechanism 2. The connecting hole 78 on the lower side of the connecting head 77 is movably connected to the connecting shaft 11. The shock-absorbing spring 75 inside the outer shell 71 is in a natural extension / retraction state, and the elastic protective sleeve 76 is in a relaxed state, without obvious stretching or compression. The adjustment mechanism 2 is also in its initial state. The motor 21 (either a servo motor or a stepper motor) is not started, the screw 23 remains stationary, and the two movable seats 24 are centered in the guide groove 22. The connecting rod 25, connecting block 26, and connecting... All connecting arms 27 show no obvious rotation, maintaining a movable connection with mounting shaft 3 and no relative displacement with the upper hinge of the adjustable shock absorber 7; the adjustable damping mechanism 73 inside the adjustable shock absorber 7 is in its initial damping state, the oil chamber 731 is filled with damping oil, piston 733 is located in the middle of the oil chamber 731, and the small funnel-shaped hole 734 in its center remains unobstructed, allowing damping oil to pass through normally; the telescopic rod 732 is at its initial length, the oil hole 738 is connected to the small hole 734, and piston 736, supported by the buffer spring 737, is located above the oil hole 738 without significant displacement; in the adjustable flow rate device 735, motor 7351 (either a servo motor or a stepper motor) is not started, and screw 7354 is stationary. The outer conical surface 7356 of the valve core 7355 and the inner conical hole 7357 of the valve body 7352 maintain a preset gap. The connecting hole 1 7358, the connecting hole 2 7359, and the conveying hole 73510 are all in a smooth state. The damping oil can flow normally between the upper and lower sides of the oil chamber 731 through this channel to maintain the initial damping force. When the vehicle travels on a bumpy road, the wheel is impacted by the road and transmits the impact force to the connecting seat 6. First, the impact force is transmitted to the connecting shaft 1 5 and the connecting shaft 2 11 through the connecting seat 6, which drives the upper connecting rod 4 to swing slightly around the mounting shaft 1 3 and the lower connecting rod 8 around the mounting shaft 2 9. The swing amplitude of the upper connecting rod 4 and the lower connecting rod 8 changes with the degree of bumpiness, which in turn drives the connecting seat 6 to make a small up and down displacement to buffer part of the impact force.The vertical displacement of the connecting seat 6 is transmitted to the connector 77 of the adjustable shock absorber 7 via the connecting shaft 2 11, causing the connector 77 to move vertically relative to the outer shell 71. When the connector 77 moves upward, the damping spring 75 between the groove 2 79 and the groove 1 74 is compressed, and at the same time, the connector 77 drives the telescopic rod 732 to move upward, pushing the piston 1 733 to move upward in the oil chamber 731. When the connector 77 moves downward, the damping spring 75 returns to its original position and extends, the telescopic rod 732 moves downward, and the piston 1 733 moves downward in the oil chamber 731. When the piston 1 733 moves vertically in the oil chamber 731, the damping oil in the oil chamber 731 is squeezed, and a portion of the damping oil passes through the flared opening in the center of the piston 1 733. The small hole 734 enters the oil hole 738 of the telescopic rod 732, squeezing the piston 736 and compressing the buffer spring 737. The elastic force of the buffer spring 737 further buffers the impact force. Another part of the damping oil enters the valve body 7352 through the connecting hole 7359 of the adjustable flow rate device 735, and flows to the lower side of the oil chamber 731 through the inner cone hole 7357, the connecting hole 7358, and the conveying hole 73510. During the flow of the damping oil, it is hindered by the gap between the valve core 7355 and the inner cone hole 7357, forming a damping force, consuming the impact force, and achieving the shock absorption effect. During this process, the adjustment mechanism 2 can be adjusted according to the degree of bumps. Specifically, when adjusting, the motor 21 is started, driving the screws 23 on the left and right sides to rotate synchronously. The movable seat 24 driven by the first 23 moves relative to or towards the guide groove 22. The movable seat 24 drives the connecting rod 25 to swing. The connecting rod 25 drives the connecting arm 27 to rotate around the mounting shaft 3 through the connecting block 26, thereby adjusting the tilt angle and initial length of the adjustable shock absorber 7 and optimizing the buffering effect. If the degree of bumpiness is large, the adjustable flow rate device 735 can adjust the damping force synchronously. The second motor 7351 starts and drives the second screw 7354 to rotate. The second screw 7354 drives the valve core 7355 to move laterally in the sliding hole 7353, adjusting the gap between the outer conical surface 7356 and the inner conical hole 7357 of the valve core 7355. When the gap decreases, the resistance to the flow of damping oil increases, the damping force is enhanced, and the buffering effect is more obvious; when the gap increases, the resistance to the flow of damping oil increases, the damping force is enhanced, and the buffering effect is more obvious. The reduced resistance to oil flow and weakened damping force prevent excessive shock absorption and body sway, adapting to different bump intensities. In addition, when the vehicle needs to turn, climb, descend, or carry different weights of cargo, the vehicle posture is adjusted through the coordinated action of the adjustment mechanism 2 and the adjustable shock absorber 7 to ensure driving stability. Specifically, the motor 21 is started, and according to the posture adjustment requirements, it drives the screw 23 to rotate forward or reverse, causing the two movable seats 24 to move towards each other (closer to the center of the frame 1) or relative to each other (away from the center of the frame 1) within the guide groove 22. When the movable seats 24 move, they drive the connecting rod 25 to swing around the upper hinge point of the movable seat 24. The connecting rod 25 pushes the connecting block 26 to move, thereby driving the connecting arm 27 to rotate around the mounting shaft 3.When the connecting arm 27 rotates, it moves synchronously with the hinge point on the upper side of the adjustable shock absorber 7, causing the outer shell 71 of the adjustable shock absorber 7 to rotate around the connecting hole 72, adjusting the tilt angle of the adjustable shock absorber 7. This, in turn, drives the connecting seat 6 to move up and down via the connecting shaft 11, thereby adjusting the vehicle height and attitude. Simultaneously, the adjustable damping mechanism 73 adjusts in sync, and the motor 7351 starts, adjusting the gap between the valve core 7355 and the inner cone hole 7357, changing the damping force of the adjustable shock absorber 7. For example, when turning, the damping force of the outer adjustable shock absorber 7 is increased, enhancing the outer support force and further suppressing vehicle roll. When handling heavy loads, the damping force of the adjustable shock absorber 7 and the compression of the shock absorber spring 75 are increased to prevent excessive vehicle body sag. Additionally, the elastic protective sleeve 76 always surrounds the outer shell 71 and the connector 77 to prevent dust and impurities from entering the adjustable shock absorber 7, protecting the shock absorber spring 75 and the adjustable damping mechanism 73, and extending the service life of the mechanism. Both motor 1 21 and motor 2 7351 are servo motors or stepper motors, enabling precise control and ensuring the attitude adjustment accuracy of the adjustment mechanism 2 and the damping force adjustment accuracy of the adjustable damping mechanism 73, adapting to the driving characteristics of new energy pure electric vehicles and balancing comfort and energy efficiency.
