[0023] See also Figure 1 In this embodiment, a high-strength automobile axle reaction rod upper bracket includes a bracket body 4, which is a common automobile axle reaction rod upper bracket on the market. External protective reinforcement ribs 5 are fixed on the left and right sides of the bracket body 4, and internal connection reinforcement ribs 6 are arranged inside the two external protective reinforcement ribs 5.

[0024] See also Figure 2-3 In order to enhance the impact resistance of the internal connection reinforcement ribs 6, the reinforcement mechanism 1 in this embodiment includes no less than two fixed boxes 107 respectively fixed on the opposite sides of the two internal connection reinforcement ribs 6, the inner cavity wall of the left and right fixed boxes 107 on the opposite sides is fixed with a first buffer spring 102, the left and right first buffer springs 102 on the opposite sides are fixed with a movable plate 103, the left and right movable plates 103 on the opposite sides are fixed with a buffer rod 106, the interior of the fixed box 107 is filled with damping fluid, the interior of the fixed box 107 is fixed with a sealing ring attached to the outside of the buffer rod 106, the left and right buffer rods 106 on the opposite sides are fixed with a buffer plate 104, and the second buffer spring 105 located on the outside of the buffer rod 106 is fixed between the buffer plate 104 and the opposite side of the fixed box 107.

[0025] The reinforcing mechanism 1 is symmetrical with respect to the central axis of the bracket body 4. Rubber plates are fixed on the opposite sides of the two buffer plates 104. The impact force is initially dispersed by the cooperation of the rubber plates and the buffer plates 104, and then a second dispersion is performed through multiple buffer rods 106, so that the impact force can be evenly distributed on the internal connection reinforcement rib 6, thereby avoiding the impact force being concentrated at one point and causing the internal connection reinforcement rib 6 to bend. Through holes for the buffer rods 106 to pass through are opened on the opposite sides of the left and right fixed boxes 107, and the buffer rods 106 are clearance-matched with the fixed boxes 107 through the through holes.

The inner cavity walls on the opposite sides of the two fixing blocks 109 are fixed with positioning springs 110, and the opposite sides of the two positioning springs 110 are fixed with positioning blocks 108 inserted into the inside of the support rod 101. The shape of the upper surfaces of the two positioning blocks 108 is semicircular. When the support rod 101 moves upward and gradually separates from the fixing block 109, it is pushed into the inside of the fixing block 109 along the semicircular surface of the positioning block 108, and the positioning spring 110 is compressed by the positioning block 108. A fixing groove for the fixing block 109 to be plugged in is provided on the lower surface of the support rod 101, and a positioning groove for the positioning block 108 to be plugged in is provided inside the support rod 101.

[0027] It should be noted that the reinforcing mechanism 1 prevents the side of the internal connection reinforcement rib 6 from being directly impacted through the cooperation of the first buffer spring 102, the movable plate 103, the buffer plate 104, the second buffer spring 105, the buffer rod 106 and the fixed box 107, and makes the intensity of the impact force be weakened twice during the transmission process, so that the impact can no longer affect the internal connection reinforcement rib 6 when it is transmitted to it, thereby preventing the internal connection reinforcement rib 6 from being directly bent.

[0028] See also Figure 4 In order to prevent the nut from being buried by the soil, the shielding mechanism 7 in this embodiment includes four limit plates 704 slidably connected to the inside of the bracket body 4, and the limit rods 705 are fixed on the opposite sides of the left and right limit plates 704. The left and right limit rods 705 are fixed on the opposite sides with shielding plates 701 slidably connected to the inside of the bracket body 4. The cross-section of the shielding plate 701 is L-shaped, and shielding grooves for sliding connection of the shielding plate 701 are provided on the left and right sides of the bracket body 4. The bottom wall of the inner cavity of the bracket body 4 is fixed with a number of not less than two limit springs 703, and the upper surface of the limit spring 703 is fixed with a limit block 702 plugged into the inside of the shielding plate 701. A nut groove for placing a nut is provided inside the bracket body 4, and a stabilizing groove for plugging the limit block 702 is provided on the lower surface of the shielding plate 701. A sealing gasket is fixed on the lower surface of the shielding plate 701 and the side close to the inner connection reinforcement rib 6.

[0029] In this embodiment, a limiting groove is opened inside the bracket body 4 for the limiting plate 704 to be slidably connected, a limiting hole is opened inside the bracket body 4 for the limiting rod 705 to pass through, and the limiting rod 705 is slidably connected to the inside of the bracket body 4 through the limiting hole.

[0030] It should be noted that the shielding mechanism 7 covers the nut part of the screw inside through the cooperation of the shielding plate 701, the limiting plate 704 and the limiting rod 705, so as to prevent it from being covered by mud and other materials during the use of the vehicle, thereby preventing the nut from being corroded and damaged by liquid inside the nut due to mud and other materials, and at the same time preventing the mud from drying in the nut groove and being easy to clean.

[0031] The working principle of the above embodiment is:

[0032] (1) After the inner connection reinforcement rib 6 and the outer protection reinforcement rib 5 are connected, the support rod 101 is placed between the inner connection reinforcement rib 6 and the side opposite to the bracket body 4, and the fixing block 109 is inserted into the inside of the support rod 101, and the arc surface of the support rod 101 with the rubber pad is in contact with the bracket body 4. When the side of the inner connection reinforcement rib 6 is impacted, it first hits the buffer plate 104 with the rubber plate, and the buffer plate 104 drives the buffer rod 106 to move toward the side close to the inner connection reinforcement rib 6. At the same time, the buffer plate 104 compresses the second buffer spring 105, and the movable plate 103 moves with the buffer rod 106 while pressing The first buffer spring 102 is compressed, and the first buffer spring 102 and the second buffer spring 105 weaken the impact strength through the rebound force, and then transmit it to the inner connecting reinforcing rib 6 through the fixed box 107. The reinforcing mechanism 1 prevents the side of the inner connecting reinforcing rib 6 from being directly hit through the cooperation of the first buffer spring 102, the movable plate 103, the buffer plate 104, the second buffer spring 105, the buffer rod 106 and the fixed box 107, and makes the strength of the impact force be weakened twice during the transmission process, so that when the impact is transmitted to the inner connecting reinforcing rib 6, it has no effect on it, thereby preventing the inner connecting reinforcing rib 6 from being directly bent.

[0033] (2) When it is necessary to remove or install screws, push the two shielding plates 701 on the bracket body 4 to the left and right sides respectively. During the movement, the shielding plates 701 are pushed into the interior of the bracket body 4 along the arc surface of the limit block 702, and the limit spring 703 is compressed by the limit block 702. When the shielding plate 701 is not in contact with the limit block 702, the limit spring 703 pushes the limit block 702 out of the bracket body 4 through the rebound force. At the same time, the limit rod 705 drives the limit plate 704 to move along with the shielding plate 701 moves together, and when the limiting plate 704 moves to the other side of the limiting groove, the threaded hole on the screw or the bracket body 4 is completely exposed, and the screw can be removed or installed at this time. The shielding mechanism 7 covers the nut part of the screw inside through the cooperation of the shielding plate 701, the limiting plate 704 and the limiting rod 705 to prevent it from being covered by mud and other materials during the use of the vehicle, thereby avoiding corrosion and damage to the nut by mud and other materials and liquid inside, and at the same time preventing mud from drying in the nut groove for easy cleaning.
