Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, and more specifically, to a sub-frame connecting plate with high bearing capacity. Background Art

[0002] Nowadays, chassis systems usually adopt a platform development model. The design and development of each chassis system needs to take into account the powertrain installation of multiple models on the same platform. The subframe, as the core and key component of the chassis system, provides connection points for parts such as powertrain suspension, control arms, stabilizer bars and steering gears. The new powertrain is equipped with two suspension connectors connected to the subframe.

[0003] The existing subframe generally only has a mounting bracket and a suspension connection between the connection sink and the powertrain on one side of the subframe, which cannot meet the connection requirements of the new powertrain.

[0004] After searching, a Chinese patent with publication number CN219969784U discloses a high-load-bearing automobile subframe. The upper and lower corresponding distribution of the first connecting plate and the second connecting plate of the utility model enables the suspension connecting member to be reliably connected to the front end of the subframe body, meeting the assembly requirements of the powertrain. In addition, the first connecting plate and the second connecting plate are fixedly connected to the subframe through the connecting frame, and the first connecting plate and the subframe body are structurally reinforced by reinforcing ribs. At the same time, the connection strength between the connecting frame and the subframe body is increased by the rotating edge, which greatly improves the load-bearing capacity of the subframe body and provides stable support for the powertrain.

[0005] However, when the above-mentioned subframe is actually used, when the car suffers a certain impact and is uncontrollable, the car's brakes may have a reduced deceleration effect. The subframe has little deceleration effect on the car when it loses control while keeping the car body stable. Utility Model Content

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] The embodiment of the present application discloses a sub-frame connecting plate with high bearing capacity, specifically comprising an upper bracket plate 1, a lower bracket plate 2 is fixedly connected to the bottom of the upper bracket plate 1, and an emergency deceleration mechanism is fixedly connected to the bottom of the lower bracket plate 2;

[0041] The emergency deceleration mechanism includes two fixed plates 3, one side of the top of the two fixed plates 3 is fixedly connected to a fixing ring 4, the inside of the two fixing rings 4 is fixedly connected to a motor 5, the output ends of the two motors 5 are coaxially connected to a rotating rod 6, both ends of the two rotating rods 6 are provided with threads 7, the outer sides of the two rotating rods 6 are movably connected to limit blocks 8, the front sides of the two fixed plates 3 are fixedly connected to two positioning plates 9, the front ends of the two rotating rods 6 are fixedly connected to a fixing block 10, the two sides of the two rotating rods 6 are movably connected to two threaded blocks 11, the bottoms of the two threaded blocks 11 are movably connected to support arms 12, and the two threaded blocks 11 are driven by the rotating rod 6 and the threads 7 on both sides to push the two load-bearing sliders 15 to move downward, so that the cross bar 18 drives the wear-resistant baffle 21 to move downward and come into contact with the ground, and decelerates to a certain extent through friction, so that the vehicle can avoid losing control and sliding for too long, causing greater hidden dangers.

[0042] Reference Figure 6 As shown, specifically, the two fixed plates 3 are fixedly connected with springs 13, the two springs 13 are movably connected with guide columns 14, the outer sides of the two guide columns 14 are movably connected with load-bearing sliders 15, the front sides of the two load-bearing sliders 15 are fixedly connected with rotating shafts 16, the outer sides of the two rotating shafts 16 are fixedly connected with two movable seats 17, the bottoms of the two load-bearing sliders 15 are fixedly connected with cross bars 18, and the cross bars 18, pushed by the two springs 13, drive the wear-resistant baffle 21 at the bottom to quickly contact the ground.

[0043] Reference Figure 4 As shown, specifically, two positioning clamps 19 are movably connected to the top of the cross bar 18, and the two positioning clamps 19 are symmetrically distributed on the top of the cross bar 18.

Wear-resistant baffles 21 are fixedly connected to the bottom of the two positioning clamps 19. The friction between the wear-resistant baffles 21 and the ground increases the friction between the vehicle and the ground, so that the vehicle can be effectively decelerated when it loses control.

[0044] Reference Figure 3 As shown, specifically, a vertical load-bearing beam 22 is fixedly connected to the top of the lower bracket plate 2, and two connecting columns 23 are fixedly connected to both sides of the top of the lower bracket plate 2.

Later, when the vehicle is in the process of driving, when the vehicle slides due to an accident and the brake system fails, the two motors 5 drive the two rotating rods 6 to rotate inside the corresponding two positioning plates 9, and the two rotating rods 6 drive the corresponding two threaded blocks 11 to be driven by the threads 7 on the outside of the two rotating rods 6 to move in opposite directions.
