The middle part of the rear mounting bracket assembly 1 is rotatably connected with a hydraulic shock absorber 13, and is located at the front end of the independent support assembly 4. The hydraulic shock absorber 13 is provided with a push rod suspension 2 near one side of the swing arm piece 3, and the connection mode of the hydraulic shock absorber 13 and the push rod suspension 2 is rotary connection. The outer side of the push rod suspension 2 is rotatably connected with one end of an anti-roll push rod 14, and the other end of the anti-roll push rod 14 is rotatably connected with the swing arm piece 3. When the outer tire 12 is disturbed by the undulating ground, the outer tire 12 will swing on the outer wall of the rear mounting bracket assembly 1 through the swing arm piece 3, and the hydraulic shock absorber 13 will drive the push rod suspension 2 to stretch through the anti-roll push rod 14, thereby damping the swing of the swing arm piece 3.

[0033] In the embodiment, the independent support assembly 4 comprises a fixed shell 401 installed in the middle of the rear mounting bracket assembly 1. The top of the fixed shell 401 is transversely provided with a limiting groove 402. The top of the fixed shell 401 is embedded with a controller 403. The inner side of the fixed shell 401 is connected with a fixed block one 404, which is provided with a plurality of groups.

The end of the support electric control cylinder 406 away from the fixed block one 404 is installed with a fixed base 408 through a fixed block two 407, and the fixed block two 407 is provided with two groups and located on the outer wall of the fixed base 408. The cross section of the fixed base 408 is a concave structure, and the fixed base 408 is provided with two groups and located in the inner cavity of the fixed shell 401, and the opposite inner walls are installed with rotating bearings 409, and the rotating bearings 409 are rotatably connected with support tires 410. The outer wall of the fixed base 408 is embedded with electric control magnets 411, and the electric control magnets 411 are provided with two groups. The electric control magnets 411 are located on one side of the fixed base 408 and the inner wall of the fixed base 408 is provided with a limiting clamping groove 412. The side of the limiting groove 402 and the opposite inner wall of the fixed shell 401 are installed with a mounting plate 413, and the bottom of the mounting plate 413 is installed with a height distance sensor 414, and the height distance sensor 414 is provided with two groups.

[0034] When the outer tire 12 is punctured and the tire bursts, the height of the rear mounting bracket assembly 1 on both sides deviates, and the rotational speed of the tires on both sides is different. At this time, the height distance sensor 414 generates data on the height of the ground, and transmits the electric signal to the controller 403 through the wire. When the set numerical parameter is reached, the controller 403 controls the support electric control cylinder 406 in the inner cavity of the fixed shell 401 to operate according to the height difference data of the rear mounting bracket assembly 1 on both sides. One end of the support electric control cylinder 406 pushes down the fixed base 408 through the fixed block two 407, so that the fixed base 408 moves down in the inner cavity of the fixed shell 401, and at the same time drives the support tire 410 to move down to contact the ground, supports the rear mounting bracket assembly 1, and keeps the vehicle body stable.

[0035] In the independent support assembly 4, when the support electric control cylinder 406 operates, if the height difference data of the height distance sensor 414 on both sides of the fixed shell 401 exists due to the tire burst, the controller 403 will control the electric control magnet 411 on the side of the fixed shell 401 with lower height to operate. The electric control magnet 411 generates magnetism after being electrified, and magnetically attracts the magnetic plug 508, so that the magnetic plug 508 slides outward on the inner wall of the connecting plate 507, and the end of the magnetic plug 508 is inserted into the inner wall of the limiting clamping groove 412, so as to fix the connecting plate 507 on the inner wall of the fixed base 408.

[0036] The limiting assembly 5 comprises a mounting base 501, two groups of which are mounted on the rear mounting support assembly 1 respectively. A rotating rod 502 is rotatably connected to the rear side wall of the mounting base 501, a push rod 503 is rotatably connected to the rotating rod 502, and the cross section of the push rod 503 is triangular structure. A pull rod 504 is rotatably connected to the end of the push rod 503 close to the outer tire 12, and a push plate 505 is rotatably connected to the end of the push rod 503 close to the support tire 410. One end of the push plate 505 extends to the inner cavity of the fixed shell 401 through the limiting slot 402 and is rotatably connected to a mounting block 506, a connecting plate 507 is mounted on the outer wall of the mounting block 506 and is slidably connected to the inner wall of the fixed base 408 on one side of the electrically controlled magnet 411. A magnetic plug 508 is slidably connected to the inner wall of the connecting plate 507, and is located on one side of the electrically controlled magnet 411 and magnetically connected to the electrically controlled magnet 411, and is connected to the limiting slot 412 in a plug-in manner. The connecting plate 507 is located directly above the rotating bearing 409. One end of the pull rod 504 is provided with a connecting base 510 through a rotating rod 509, and the connecting base 510 is connected with the swing arm 3. When the fixed base 408 moves downward, the connecting plate 507 moves downward, the connecting plate 507 drives the push plate 505 to move downward through the mounting block 506, so that the push plate 505 pulls one end of the push rod 503 downward. The push rod 503 rotates on the outer wall of the rotating rod 502, the other end drives the pull rod 504 to move upward, the pull rod 504 drives the connecting base 510 to move upward through the rotating rod 509, and then the connecting base 510 drives the swing arm 3 to move upward, so that the tire burst side is lifted by the upward pulling force of the limiting assembly 5, preventing the hub from being damaged by friction with the ground.

[0037] The protection assembly 6 comprises a mounting bottom block 601, which is provided with a plurality of groups and is located at the bottom corners of the fixed shell 401 respectively. A threaded sleeve 602 is embedded in the top of the mounting bottom block 601. A bottom protection shell 603 is mounted on the bottom of the mounting bottom block 601, which is located directly below the rear mounting support assembly 1. The bottom protection shell 603 is provided with a plurality of fixed bolts 604, which are located on the bottom outer wall of the bottom protection shell 603 respectively, and are threadedly connected with the threaded sleeve 602 through the bottom protection shell 603. A support column 605 is mounted on the inner wall of the bottom protection shell 603, and an inner gasket 606 is mounted on the outer wall of the support column 605. The bottom protection shell 603 is fixed on the bottom outer wall of the mounting bottom block 601 by the fixed bolts 604, and protects the bottom of the rear mounting support assembly 1. When the bottom protection shell 603 is broken, the inner gasket 606 buffers the impact of foreign matter.

[0038] The controller 403 is connected to the support electric control cylinder 406, the electric control magnet 411 and the height distance sensor 414 through wires respectively, and the connection mode is electrical connection, so that the controller 403 can control the support electric control cylinder 406, the electric control magnet 411 and the height distance sensor 414 to operate after the device is powered on.

[0039] When the automobile rear independent suspension swing arm mounting bracket assembly works, the swing arm pieces 3 are rotatably connected on the opposite outer walls of the rear mounting bracket assembly 1, and there are two groups, which are respectively located on the two sides of the outer wall. The wheel hub bearing 7 is installed at one end of the swing arm piece 3, and when the outer tire 12 is shaken by the undulating ground, the swing arm piece 3 can swing on the outer wall of the rear mounting bracket assembly 1. The hydraulic shock absorber 13 is rotatably connected to the inner wall of the rear mounting bracket assembly 1, and the push rod suspension 2 is arranged on one side of the inner wall, and the two are rotatably connected. The anti-roll push rod 14 is rotatably connected to the outer wall of the push rod suspension 2, and one end of the anti-roll push rod 14 is rotatably connected to the swing arm piece 3. The swing arm piece 3 drives the push rod suspension 2 to move at one end through the anti-roll push rod 14, and then drives the hydraulic shock absorber 13 to stretch at the other end of the push rod suspension 2, so as to realize shock absorption.

[0040] When the outer tire 12 is punctured, the height of the rear mounting bracket assembly 1 on both sides appears deviation, and the tire rotates at different speeds. The mounting plate 413 is installed on the inner wall of the fixed shell 401 on one side of the limiting groove 402, and two groups of height distance sensors 414 are installed on the bottom outer wall of the mounting plate 413. The height distance sensor 414 transmits data to the controller 403, and when the set value is reached, the controller 403 controls the support electric control cylinder 406 in the inner cavity of the fixed shell 401 to operate according to the height difference data. The support electric control cylinder 406 applies a downward pushing force to the fixed base 408 through the fixed block two 407 at one end, so that the fixed base 408 moves downward in the inner cavity of the fixed shell 401. The fixed base 408 drives the support tire 410 to move downward through the rotating bearing 409, and supports the rear mounting bracket assembly 1 after contacting the ground, so as to keep stable, thereby effectively dealing with the problem of body inclination out of control caused by tire puncture in the use process of the independent suspension swing arm mounting bracket, and the defect that the existing swing arm bracket lacks auxiliary support structure, so that the body inclination cannot be adjusted in time when the tire is punctured.

[0041] When the support electric control cylinder 406 in the independent support assembly 4 operates, if the tire burst causes the height difference of the height ranging sensors 414 on both sides of the fixed shell 401, the controller 403 controls the electric control magnet 411 on the side of the fixed shell 401 with lower height to operate. The electric control magnet 411 generates magnetism after being powered on, and is arranged on the inner wall of the fixed base 408. There are two groups of the electric control magnet 411. The inner wall of the fixed base 408 on one side of the electric control magnet 411 is provided with a limiting clamping groove 412. The inner wall of the connecting plate 507 is slidably connected with a magnetic attraction pin 508 located on one side of the electric control magnet 411, and the magnetic attraction pin 508 and the limiting clamping groove 412 are magnetically connected and are connected in a plug-in manner. The magnetic attraction pin 508 is attracted by the electric control magnet 411, so that it slides outward on the inner wall of the connecting plate 507, and one end is inserted into the inner wall of the limiting clamping groove 412 to fixedly connect the connecting plate 507 on the inner wall of the fixed base 408.

[0042] The outer wall of one side of the push rod 503 is rotatably connected with a pull rod 504, and the outer wall of the other side is rotatably connected with a push plate 505. The connecting plate 507 is located directly above the rotating bearing 409. One end of the pull rod 504 is connected with a connecting base 510 through a rotating rod 509, and the connecting base 510 is connected with the swing arm assembly 3. When the fixed base 408 moves downward, the magnetic attraction pin 508 drives the connecting plate 507 to move downward, the connecting plate 507 drives the push plate 505 to move downward through the mounting block 506, so that one end of the push plate 505 pulls the push rod 503. The push rod 503 rotates on the outer wall of the rotating rod 502, the other end drives the pull rod 504 to move upward, the connecting base 510 is driven to move upward through the rotating rod 509, and then the swing arm assembly 3 rotates upward on the outer wall of the rear mounting bracket assembly 1, the tire burst side is lifted by the limiting component 5, and the tire burst side is lifted by the limiting component 5, thereby preventing the hub from being damaged by friction with the ground, thereby effectively solving the problem of simple installation bracket structure, avoiding the problem that the tire steel ring is deformed due to friction with the ground when the tire bursts due to the lack of adjustment function of the installation bracket, thereby reducing the subsequent maintenance cost.

[0043] A plurality of groups of threaded sleeves 602 are located on the outer wall of the mounting bottom block 601. A bottom protective shell 603 is installed on the outer wall of the bottom of the mounting bottom block 601 and is located directly below the rear mounting bracket assembly 1. A plurality of groups of fixed bolts 604 are installed on the bottom of the bottom protective shell 603.

A support column 605 is installed on the inner wall of the bottom protective shell 603, and an inner gasket plate 606 is installed on the outer wall of the support column 605. The bottom protective shell 603 protects the bottom of the rear mounting bracket assembly 1. When the bottom protective shell 603 is broken, the inner gasket plate 606 buffers the impact of foreign matters, thereby effectively avoiding the problem that the bottom of the independent suspension swing arm is directly exposed to the impact of road splashes (such as stones and foreign matters), thereby prolonging the service life and solving the defect that the protection measure of the independent suspension swing arm is insufficient in the prior art.
