A connecting column 5 is fixedly mounted on one end of the fixed block 4. A limiting block 6 is fixedly mounted on the connecting column 5. A sleeve 7 is sleeved on the connecting column 5. A limiting hole 8 adapted to the limiting block 6 is opened on the sleeve 7. One end of the sleeve 7 is arranged in a spherical shape. A plurality of arc-shaped clamping rings 9 connected to the sleeve 7 are fixedly mounted on one end of the spring assembly body 2. By setting the adjustment structure 3, the distance between the automobile frame body 1 and the spring assembly body 2 can be adjusted to adapt to different road conditions, and the spring assembly body 2 can adjust its supporting force and stiffness according to changes in road conditions; the limit block 6 on the connecting column 5 is aligned with the limit hole 8 and inserted to fix the sleeve 7 on the connecting column 5, and then the arc-shaped snap ring 9 on the spring assembly body 2 is installed on the sphere set at one end of the sleeve 7, and the sphere can rotate inside the arc-shaped snap ring 9. Therefore, when the car turns, the spring assembly body 2 can change its own stiffness according to the steering angle of the car, and make adjustments at one time, thereby improving the driving experience of the driver.

[0020] like Figure 4 As shown, a slide groove 10 is provided at one end of the spring assembly body 2, and a slider 11 connected to the arc-shaped retaining ring 9 is slidably installed inside the slide groove 10, and a bidirectional screw rod 12 connected to the spring assembly body 2 is movably installed on the slider 11; after the spherical body at one end of the sleeve 7 is installed between the arc-shaped retaining rings 9, the bidirectional screw rod 12 is rotated to drive the two sliders 11 to move closer to each other. When the slider 11 moves, multiple arc-shaped retaining rings 9 also move closer to each other, so that the sleeve 7 can be clamped to prevent the sleeve 7 from sliding off from the arc-shaped retaining ring 9. The arc-shaped retaining ring 9 can be opened by rotating the bidirectional screw rod 12 to move the sliders 11 away from each other, which facilitates the disassembly and installation of the sleeve 7.

[0021] like Figure 1 As shown, a connecting rod 13 is installed at the other end of the spring assembly body 2, and a movable rod 14 is movably installed inside the connecting rod 13, and a push block 15 is installed at one end of the movable rod 14. A fixed frame 16 is arranged on the outer side of the push block 15, and a first spring 17 connected to the push block 15 is fixedly installed on the inner wall of the fixed frame 16; when the impact force applied to the spring assembly body 2 is too large, the movable rod 14 will push the push block 15 to move during the swinging process, and the push block 15 will squeeze the first spring 17 when it moves to make it contract and buffer a part of the impact force, which can play a certain protective effect on the spring assembly body 2 and prevent the spring assembly body 2 from being damaged due to excessive impact force.

[0022] like Figure 5As shown, a fixing collar 18 sleeved on the connecting rod 13 is fixedly installed at the bottom of the spring assembly body 2, and a cross hole 19 is opened on the connecting rod 13 and the fixing collar 18, and an insert rod 20 is installed inside the cross hole 19, and a cross bolt 21 adapted to the cross hole 19 is fixedly installed on one end of the insert rod 20; the connecting rod 13 is inserted into the cross hole 19, and then the insert rod 20 is inserted into the cross hole 19 until it penetrates to the other side of the fixing collar 18, and the insert rod 20 is rotated so that the angle of the cross bolt 21 is adjusted to be perpendicular to the cross hole 19, so that the connecting rod 13 can be fixed on the spring assembly body 2, and when the insert rod 20 is rotated, the cross bolt 21 is aligned with the cross hole 19, and the insert rod 20 can be pulled out, and after the insert rod 20 is detached from the inside of the cross hole 19, the transmission structure on the connecting rod 13 can be disassembled and replaced.

[0023] like Figure 3 As shown, a plurality of clamping plates 22 are arranged on the outer side of the sleeve 7, and two clamping plates 22 are connected by a plurality of first bolts 23; the plurality of clamping plates 22 are sleeved on the sleeve 7, and the clamping plates 22 sleeved on the sleeve 7 are fixed by a plurality of first bolts 23, so that the connecting column 5 is more stable inside the sleeve 7, and it is prevented from falling off from the sleeve 7 when it is subjected to vibration or the torque of the vehicle is large.

[0024] like Figure 1 As shown, a plurality of fixing rings 24 are installed on the inner side of the automobile frame body 1, and a shock absorber 25 is fixedly installed between two fixing rings 24; the setting of the fixing rings 24 and the shock absorber 25 can support the automobile frame body 1 and buffer the impact force. When the vehicle is subjected to a severe collision, the shock absorber 25 can reduce the impact force received and prevent the vehicle from rolling over.

[0025] like Figure 6 As shown, threaded holes 26 are provided on the automobile frame body 1 and the fixing ring 24, and a second bolt 27 connected to the fixing ring 24 is movably installed inside the threaded hole 26, and a plurality of tooth grooves are provided at one end of the second bolt 27; the arrangement of the threaded hole 26 and the second bolt 27 can fix the fixing ring 24 on the inner side of the automobile frame body 1 to prevent it from falling, and the shock absorber 25 can be disassembled and replaced after loosening and detaching the second bolt 27.

[0026] like Figure 6 As shown, a plurality of fixing plates 28 are fixedly installed on the outer side of the automobile skeleton body 1, an electric telescopic rod 29 is fixedly installed on the top of the fixing plate 28, and a latching tooth 30 is fixedly installed on the output end of the electric telescopic rod 29; after the plurality of second bolts 27 are tightened to fix the fixing ring 24, the plurality of electric telescopic rods 29 are started to drive the latching tooth 30 to engage with the latching groove on one end of the second bolt 27, so as to prevent the second bolt 27 from rotating and loosening after being vibrated, thereby causing the fixing ring 24 to fall off.

[0027] like Figure 7-8 As shown, a plurality of mounting holes 31 are provided at the output end of the electric telescopic rod 29, a second spring 32 is fixedly installed inside the mounting hole 31, a clamping block 33 is fixedly installed at one end of the second spring 32, a socket 34 adapted to the output end of the electric telescopic rod 29 is provided on the clamping tooth 30, and a plurality of clamping holes 35 used in conjunction with the clamping block 33 are provided on the inner wall of the socket 34; the clamping block 33 is engaged with the clamping hole 35 under the elastic action of the second spring 32, thereby fixing the clamping tooth 30 on the electric telescopic rod 29, and when the clamping tooth 30 is pulled, the clamping block 33 is squeezed and contracted to the inside of the mounting hole 31, and the clamping tooth 30 can be removed, so that the disassembly and replacement of the clamping tooth 30 is convenient.

[0028] like Figure 4 As shown, one end of the block 33 is arranged to be arc-shaped, and one end of the bidirectional screw rod 12 is fixedly installed with a plurality of gripping rods 36; the arc-shaped end of the block 33 and the setting of the gripping rod 36 can reduce the friction force at one end of the block 33, making it easier for the block 33 to slide in the card hole 35, facilitating the disassembly and installation of the card tooth 30, and the gripping rod 36 can increase the force-bearing area at one end of the bidirectional screw rod 12, making it easier for the bidirectional screw rod 12 to rotate.

[0029] The working process of the adjustable support vehicle frame spring assembly provided in this embodiment is as follows: The sleeve 7 can be fixed on the connecting column 5 by aligning the limiting block 6 on the connecting column 5 with the limiting hole 8 and inserting it. Then the arc-shaped snap ring 9 on the spring assembly main body 2 is installed on the sphere set at one end of the sleeve 7, and the sphere can rotate inside the arc-shaped snap ring 9. Therefore, when the car turns, the spring assembly main body 2 can change its own stiffness according to the steering angle of the car. Adjustments can be made at one time to improve the driving experience of the driver and increase the application range of the spring assembly main body 2.
