Description

Technical Field

[0001] This utility model relates to the field of front bumper bracket technology, specifically an adjustable front bumper reinforcement bracket connection mechanism. Background Technology

[0002] With the increasing popularity of automobiles, driver safety is receiving more and more attention. Cars are equipped with bumpers at both the front and rear. Bumpers play a crucial role in car collision safety. The front bumper prevents external damage from affecting the vehicle's safety systems, and when the vehicle collides with other objects, the bumper protects important components of the car, minimizing damage.

[0003] A search revealed a Chinese patent (CN219948129U) disclosing a front bumper connecting bracket, comprising a crossbeam body and a connecting assembly mounted on the crossbeam body. The crossbeam body includes a first plane and a third plane arranged opposite each other, and a second plane for connecting the first plane and the third plane. The connecting assembly includes a bracket assembly, a first connector for connecting the front grille, and a second connector for connecting the front bumper. The first plane has mounting holes at both ends for mounting headlights. The first connector is located on the first plane, and the second connector is axially located on the first plane along the crossbeam body. The bracket assembly is axially located on the third plane along the crossbeam body to fix the crossbeam body to the front end of the driver's cab. This invention reduces the load on the front bumper by designing a fixed crossbeam behind the front bumper to connect with the front grille and headlights, and connects it to the front bumper via a bracket assembly, while also facilitating the maintenance and replacement of the front bumper.

[0004] In the aforementioned patented technology, the front bumper is connected to the bracket assembly, which reduces the load on the front bumper and also facilitates the maintenance and replacement of the front bumper. However, in actual use, there may be dimensional deviations in the crossbeam body and the front of the cab. If there is a slight angular deviation between the crossbeam body and the front of the cab, the rigidly connected bracket assembly cannot adaptively adjust, which may lead to uneven stress on the crossbeam body. Long-term use may cause cracking of the bracket welding points or loosening of bolts. Therefore, we propose an adjustable front bumper reinforcement bracket connection mechanism. Utility Model Content

[0005] The technical problem to be solved by this application is that when the above-mentioned patent is used, there may be dimensional deviations in both the crossbeam body and the front end of the cab. If there is a slight angular deviation between the crossbeam body and the front end of the cab, the rigidly connected bracket assembly cannot adaptively adjust, which may lead to uneven stress on the crossbeam body. Long-term use may easily cause cracking of the bracket welding points or loosening of bolts.

[0006] To solve the above technical problems, this application provides an adjustable front bumper reinforcement bracket connection mechanism, including a front bumper crossbeam. Two connecting brackets are installed on the rear side of the front bumper crossbeam. The two connecting brackets include a connecting seat and a fixed bracket. The connecting seat and the fixed bracket are connected by an angle adjustment component, which is used to adjust the angle between the fixed bracket and the connecting seat.

[0007] The angle adjustment assembly includes a support shaft that is fixedly inserted through the surface of the connecting seat. One end of the fixed bracket is rotatably sleeved on the outside of the support shaft. One end of the support shaft has a threaded tooth. A nut is threaded onto the outer surface of the threaded tooth. An arc-shaped cylinder is movably arranged between the fixed bracket and the surface of the nut. An abutment plate is provided on the side of the arc-shaped cylinder facing the fixed bracket. The fixed plate is sleeved on the outer surface of the support shaft. The other end of the arc-shaped cylinder is movably fitted with the surface of the nut.

[0008] In some embodiments, the fixed bracket is movably fitted between the fixed plate and the abutment plate, and the rotation of the fixed bracket on the support shaft is controlled by adjusting the magnitude of the friction between the fixed plate and the abutment plate and the fixed bracket.

[0009] In some embodiments, the connecting bracket further includes an adjusting bracket, which is movably inserted inside the fixed bracket.

[0010] In some embodiments, the outer surface of the fixed bracket is threaded through a limit bolt, and the outer surface of the adjusting bracket is provided with a plurality of screw holes arranged in a linear array.

[0011] In some embodiments, the other end of the adjusting bracket is provided with a mounting plate, and the outer surface of the mounting plate is provided with a waist hole.

[0012] In some embodiments, the mounting plate is connected to the adjustment bracket via an angle adjustment assembly.

[0013] In some embodiments, both the nut and the limiting bolt are wing bolts.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. This utility model allows the fixed bracket to rotate on the support shaft by loosening the nut, thereby adjusting the tilt angle between the fixed bracket and the connecting seat. By tightening the nut in conjunction with the arc-shaped cylinder, the abutment plate, and the fixing plate, the fixed bracket is secured. The angle between the mounting plate and the adjusting bracket is adjusted in the same way, thereby enabling fine-tuning of the angle of the connecting bracket. This avoids minor dimensional errors between the front bumper crossbeam and the front of the car's cab, thus preventing uneven stress on the front bumper crossbeam and the phenomenon that long-term use may lead to cracking of the bracket welding points or loosening of bolts.

[0016] 2. This utility model allows the adjustable bracket to slide within the fixed bracket, and the relative lengths of the adjustable bracket and the fixed bracket can be adjusted by using limit bolts and screw holes. This allows the adjustment of the length of the connecting bracket to accommodate the differences in distance between the front bumper crossbeam and the cab of different vehicle models.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: Please refer to Figures 1-4 This utility model provides a technical solution: an adjustable front bumper reinforcement bracket connection mechanism, including a front bumper crossbeam 1, with two connecting brackets 2 installed on the rear side of the front bumper crossbeam 1. The two connecting brackets 2 include a connecting seat 21 and a fixed bracket 22. The connecting seat 21 and the fixed bracket 22 are connected by an angle adjustment component. The angle adjustment component is used to adjust the included angle between the fixed bracket 22 and the connecting seat 21. Specifically, by adjusting the included angle between the fixed bracket 22 and the connecting seat 21 through the angle adjustment component, the angle of the connecting bracket 2 is finely adjusted to avoid slight dimensional errors between the front bumper crossbeam 1 and the front of the car's driver's cab, thereby avoiding uneven stress on the front bumper crossbeam 1 and the phenomenon that long-term use may easily cause cracking of the bracket welding points or loosening of bolts.

[0024] The angle adjustment assembly includes a support shaft 3 fixedly extending through the surface of the connecting seat 21. One end of a fixed bracket 22 is rotatably sleeved on the outside of the support shaft 3. One end of the support shaft 3 has a threaded tooth 31, and a nut 32 is threaded onto the outer surface of the threaded tooth 31. An arc-shaped cylinder 33 is movably disposed between the surfaces of the fixed bracket 22 and the nut 32. An abutment plate 34 is disposed on the side of the arc-shaped cylinder 33 facing the fixed bracket 22. A fixed plate 35 is sleeved on the outer surface of the support shaft 3. The other end of the arc-shaped cylinder 33 is movably fitted against the surface of the nut 32. Specifically, loosening the nut 32... 2. This causes the nut 32 to detach from the surface of the arc-shaped cylinder 33, creating a gap between the abutment plate 34 and the surface of the fixed bracket 22. This reduces the friction between one end of the fixed bracket 22 and the abutment plate 34 and the fixed plate 35, allowing the fixed bracket 22 to rotate on the support shaft 3. This adjusts the tilt angle between the fixed bracket and the connecting seat 21. After adjustment, tighten the nut 32 to increase the friction between the abutment plate 34 and the fixed bracket 35, locking the position of the fixed bracket 22.

[0025] Furthermore, the fixed bracket 22 is movably fitted between the fixed plate 35 and the abutment plate 34. By adjusting the magnitude of the friction between the fixed plate 35 and the abutment plate 34 and the fixed bracket 22, the rotation of the fixed bracket 22 on the support shaft 3 is controlled. Specifically, when the friction between the fixed plate 35 and the abutment plate 34 and the fixed bracket 22 decreases, the fixed bracket 22 can slide on the outer surface of the support shaft 3. When the friction between the fixed plate 35 and the abutment plate 34 and the fixed bracket 22 increases, it becomes difficult for the fixed bracket 22 to slide on the surface of the support shaft 3.

[0026] Furthermore, the connecting bracket 2 also includes an adjusting bracket 23, which is movably inserted inside the fixed bracket 22. Specifically, by sliding the adjusting bracket 23 inside the fixed bracket 22, the relative lengths of the adjusting bracket 23 and the fixed bracket 22 are adjusted, thereby adjusting the overall length of the connecting bracket 2.

[0027] Furthermore, the outer surface of the fixed bracket 22 is threaded through the limit bolt 41, and the outer surface of the adjusting bracket 23 is provided with a number of screw holes 4 arranged in a linear array. Specifically, after adjusting the relative length of the adjusting bracket 23 in the movable bracket, the limit bolt 41 is tightened so that the limit bolt 41 is screwed into the corresponding screw hole 4, thereby limiting the length between the fixed bracket 22 and the adjusting bracket 23, and thus adjusting the relative length between the fixed bracket 22 and the adjusting bracket 23.

[0028] Furthermore, the other end of the adjusting bracket 23 is provided with a mounting plate 24. The outer surface of the mounting plate 24 is provided with waist holes. Specifically, the mounting plate 24 is aligned with the front end of the cab, and the bolts are screwed into the corresponding waist holes to install the mounting plate 24 at the front end of the cab. When there is a small gap between the mounting plate 24 and the front end of the cab, a shim can be added at the waist hole. The shim is placed at the waist hole, and the bolt passes through the shim to compensate for the gap, increase the stability of the bolt connection, and reduce the possibility of abnormal noise during driving.

[0029] Furthermore, the mounting plate 24 is connected to the adjusting bracket 23 via an angle adjustment assembly. Specifically, the mounting plate 24 is connected to the adjusting bracket 23 via the angle adjustment assembly, thereby adjusting the tilt angle between the mounting plate 24 and the adjusting bracket 23 so that the mounting plate 24 remains parallel to the front end of the cab, so as to avoid tilting error between the mounting plate 24 and the front end of the cab, which would affect the stability of the bolts.

[0030] Furthermore, both the nut 32 and the limiting bolt 41 are wing bolts. Specifically, the wing bolts facilitate the application of force to rotate the nut 32 and the limiting bolt 41. Traditional bolts require tools such as wrenches and screwdrivers to tighten and loosen, while the wing-shaped head of the wing bolt can be held directly with the fingers, and the tightening and loosening operations can be completed by applying force with the hand.

[0031] Based on the above embodiments, the following is the complete working principle of the above embodiments: In use, the front bumper beam 1 is connected to the front bumper of the car, and the front bumper beam 1 is connected to the front of the car cab through the connecting bracket 2. During installation, according to the dimensional error between the front bumper beam 1 and the front of the cab beam, the tilt angle between the fixing bracket 22 and the connecting seat 21 is adjusted. At this time, the nut 32 is loosened so that the nut 32 is detached from the surface of the arc-shaped cylinder 33, thereby creating a gap between the abutment plate 34 and the surface of the fixing bracket 22. This reduces the friction between one end of the fixing bracket 22 and the abutment plate 34 and the fixing plate 35, allowing the fixing bracket 22 to rotate on the support shaft 3, thereby adjusting the fixing bracket and the connecting seat 21. After adjusting the tilt angle between the seats 21, tighten the nut 32 to increase the friction between the fixing bracket 22 and the fixing plate 34 and the fixing plate 35 bracket, locking the position of the fixing bracket 22. Then, adjust the tilt angle between the mounting plate 24 and the adjusting bracket 23 in the same way so that the mounting plate 24 is parallel to the front of the cab. By screwing the bolt into the oblong hole of the mounting plate 24, the mounting plate 24 is installed at the front of the cab. This allows for fine adjustment of the angle of the connecting bracket 2, avoiding minor dimensional errors between the front bumper beam 1 and the front of the cab, thus preventing uneven stress on the front bumper beam 1 and the phenomenon of cracking of the bracket welding points or loosening of bolts after long-term use.

[0032] The adjustable bracket 23 can slide within the fixed bracket 22. After adjusting the relative length of the adjustable bracket 23 and the fixed bracket 22 to a suitable length, the limiting bolt 41 is screwed into the corresponding screw hole 4 to limit the adjustable bracket 23 and the fixed bracket 22. If there is still a gap between the mounting plate 24 and the front end of the cab after adjusting the length, a shim can be added. The shim is placed at the waist hole and the bolt passes through the shim to compensate for the gap, increase the stability of the bolt connection, and reduce the possibility of abnormal noise during driving. Thus, by adjusting the length of the connecting bracket 2, the distance difference between the front bumper beam 1 and the cab of different models can be adapted.
