Technical Field
[0001] This utility model relates to the field of reinforcing plate technology, and in particular to a reinforcing plate for a front subframe. Background Technology
[0002] In the existing technology, the front subframe reinforcement plate is an important reinforcing component of the front subframe structure of a car chassis. Its core function is to enhance the overall structural strength and rigidity of the front subframe, reduce the deformation and vibration of the subframe during vehicle driving (especially when driving on bumpy roads, turning, or during rapid acceleration or braking), thereby improving chassis stability.
[0003] However, traditional reinforcing plates lack a protective structure on the side closest to the ground at the bottom. If a vehicle encounters a stone or protrusion during a collision, it is prone to dents or deformation, thus shortening the service life of the reinforcing plate. Summary of the Invention
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a front subframe reinforcement plate.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A front subframe reinforcement plate includes a reinforcement plate body, a weight reduction groove on the top of the reinforcement plate body, a parts replacement mechanism at the end corner of the reinforcement plate body, an ear plate installed at the end corner of the reinforcement plate body through the parts replacement mechanism, and an impact resistance mechanism at the bottom of the reinforcement plate body.
[0006] As a further improvement of this utility model: a nitrile rubber pad is embedded in the top of the reinforcing plate body, and an installation hole is passed through the top of the nitrile rubber pad. An annular groove is opened in the installation hole, and a screw is placed in the annular groove. The screw is connected to the reinforcing plate body by threads.
[0007] As a further embodiment of this utility model: the parts replacement mechanism includes a mounting groove body, bolts, nuts, hexagonal protrusions and cotter pins, and the mounting groove body is provided at the end corner of the reinforcing plate body.
[0008] As a further embodiment of this utility model: an ear plate is placed on the top of the mounting groove body, and a threaded hole is opened at the bottom of the inner wall of the mounting groove body. The bolt is connected to the inner wall of the threaded hole opened in the mounting groove body by thread, and the bolt passes through the bottom of the ear plate. A hole is opened on the outer surface of the bolt, and the nut is connected to the outer wall of the bolt by thread.
[0009] As a further embodiment of this utility model: the hexagonal protrusion is welded to the top of the nut, the cotter pin is inserted into the inner wall of the hole opened by the bolt, and the cotter pin passes through the gap of the hexagonal protrusion.
[0010] As a further embodiment of this utility model: the impact-resistant mechanism includes a trapezoidal mounting groove, a steel plate one, a positioning hole, an aluminum alloy honeycomb core, a positioning pin, and a steel plate two, and the bottom of the reinforcing plate body is provided with a trapezoidal mounting groove, the inner wall of the trapezoidal mounting groove is welded with a steel plate one, and the steel plate one is provided with a positioning hole.
[0011] As a further embodiment of this utility model: the second steel plate is welded to the inner wall of the trapezoidal mounting groove, the aluminum alloy honeycomb core is placed between the second steel plate and the first steel plate, the bottom of the aluminum alloy honeycomb core has a through hole, the positioning pin is welded to the top of the second steel plate, the other end of the positioning pin is inserted into the positioning hole, and the positioning pin passes through the inner wall of the through hole of the aluminum alloy honeycomb core.
[0012] Compared with the prior art, this utility model provides a reinforcing plate for the front subframe, which has the following beneficial effects: 1. The nitrile rubber pad is installed on the top of the reinforcing plate body using screws and annular grooves. The nitrile rubber pad between the reinforcing plate body and the front auxiliary workshop forms an elastic buffer layer to absorb the vibration energy of the vehicle during driving. Then, the ear plate is installed at the end corner of the reinforcing plate body through the parts replacement mechanism. If the ear plate is worn or needs to be adapted to different hole spacing requirements, it can be replaced through the parts replacement mechanism. During vehicle operation, the impact-resistant mechanism resists the impact of ground protrusions, thereby protecting the reinforcing plate body. Thus, the impact-resistant mechanism is combined with the bottom of the reinforcing plate body to resist the impact of ground protrusions, reduce the impact damage to the reinforcing plate body, and improve the life of the reinforcing plate body. In addition, the ear plate can be installed and removed through the parts replacement mechanism to reduce the maintenance cost of the reinforcing plate body.
[0013] 2. Place the ear plate to be installed in the mounting groove of the reinforcing plate body at the end corner. Then, screw the bolt shank into the threaded hole at the bottom of the mounting groove body and through the ear plate. Next, screw the nut into the top of the bolt while the hexagonal protrusion moves synchronously until the nut is close to the top of the ear plate. Finally, pass one end of the cotter pin through the gap between the hexagonal protrusions and insert it into the pre-set hole on the outer surface of the bolt. Then, pry the two ends of the cotter pin outward so that the cotter pin fits against the outer surface of the hexagonal protrusion. When the ear plate needs to be replaced, use pliers to reset the two ends of the cotter pin, pull the cotter pin out of the bolt hole, release the lock on the nut, reverse the nut, and remove the nut and hexagonal protrusion. In this way, the bolt is prevented from loosening by the cooperation of the cotter pin and the hexagonal protrusion, and there is no need to re-drill holes in the reinforcing plate body or replace the reinforcing plate body for different hole spacings, which reduces the material cost of component replacement.
[0014] 3. Steel plates one and two are completely fixed to the inner wall of the trapezoidal mounting groove, forming a closed chamber. The trapezoidal mounting groove is located in the non-stress area of the reinforcing plate body. The aluminum alloy honeycomb core is positioned using positioning holes and positioning pins. The aluminum alloy honeycomb core is clamped between steel plates one and two. When the protrusion first impacts the outer surface of steel plate two, steel plate two initially disperses the impact force through slight deformation, preventing the impact force from being directly concentrated at one point and transmitted to the aluminum alloy honeycomb core. The remaining impact force that is not dispersed is transmitted to the aluminum alloy honeycomb core. The porous structure of the aluminum alloy honeycomb core... Thin-walled structures deform, and the pore walls of the aluminum alloy honeycomb core are compressed and folded, converting the kinetic energy generated by the impact into structural deformation. At the same time, the aluminum alloy honeycomb core disperses the impact force in different directions. After the energy is absorbed by the aluminum alloy honeycomb core, the impact force is finally transmitted to the inner wall of the steel plate and the trapezoidal mounting groove. Thus, under the impact force absorbed by the steel plate and the aluminum alloy honeycomb core, the damage to the main body of the reinforcing plate is reduced under the same impact force. Meanwhile, the welded and sealed steel plate protects the aluminum alloy honeycomb core from dust and rainwater entering the aluminum alloy honeycomb core and affecting its energy absorption effect.
[0015] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0021] A type of front subframe reinforcement plate, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the device includes a reinforcing plate body 1, a weight-reducing groove 2 on the top of the reinforcing plate body 1, a parts replacement mechanism 4 at the end corner of the reinforcing plate body 1, an ear plate 3 installed at the end corner of the reinforcing plate body 1 through the parts replacement mechanism 4, a nitrile rubber pad 5 embedded in the top of the reinforcing plate body 1, and a mounting hole through the top of the nitrile rubber pad 5, an annular groove in the mounting hole, a screw 6 inside the annular groove, and the screw 6 connected to the reinforcing plate body 1 by threads, and an impact-resistant mechanism 7 at the bottom of the reinforcing plate body 1.
[0022] The nitrile rubber pad 5 is installed on the top of the reinforcing plate body 1 using screws 6 and annular grooves. The nitrile rubber pad 5 forms an elastic buffer layer between the reinforcing plate body 1 and the front auxiliary workshop to absorb the vibration energy of the vehicle during driving. Then, the ear plate 3 is installed at the end corner of the reinforcing plate body 1 through the parts replacement mechanism 4. If the ear plate 3 is worn or needs to be adapted to different hole spacing requirements, the ear plate 3 can be replaced through the parts replacement mechanism 4. During vehicle driving, the impact-resistant mechanism 7 resists the impact of ground protrusions, thereby protecting the reinforcing plate body 1. Thus, the impact-resistant mechanism 7 is combined with the bottom of the reinforcing plate body 1 to resist the impact of ground protrusions, reduce the impact damage to the reinforcing plate body 1, and improve the service life of the reinforcing plate body 1. In addition, the ear plate 3 can be installed and removed through the parts replacement mechanism 4 to reduce the maintenance cost of the reinforcing plate body 1.
[0023] To facilitate the replacement of ear plate 3, such as Figure 4 As shown, the parts replacement mechanism 4 includes a mounting groove body 401, a bolt 402, a nut 403, a hexagonal protrusion 404, and a cotter pin 405. The mounting groove body 401 is provided at one end corner of the reinforcing plate body 1. An ear plate 3 is placed on the top of the mounting groove body 401. A threaded hole is provided at the bottom of the inner wall of the mounting groove body 401. The bolt 402 is threadedly connected to the inner wall of the threaded hole in the mounting groove body 401 and passes through the bottom of the ear plate 3. A hole is provided on the outer surface of the bolt 402. The nut 403 is threadedly connected to the outer wall of the bolt 402. The hexagonal protrusion 404 is welded to the top of the nut 403. The cotter pin 405 is inserted into the inner wall of the hole in the bolt 402 and passes through the gap of the hexagonal protrusion 404.
[0024] Place the ear plate 3 to be installed into the mounting groove body 401 at the end corner of the reinforcing plate body 1. Then, screw the shank of the bolt 402 into the threaded hole at the bottom of the mounting groove body 401 and through the ear plate 3. Next, screw the nut 403 into the top of the bolt 402, while the hexagonal protrusion 404 moves synchronously until the nut 403 is pressed against the top of the ear plate 3. Finally, pass one end of the cotter pin 405 through the gap between the protrusions of the hexagonal protrusion 404 and insert it into the pre-set hole on the outer surface of the bolt 402. Finally, pry the two ends of the cotter pin 405 outwards to make... The cotter pin 405 fits against the outer surface of the hexagonal protrusion 404. When the ear plate 3 needs to be replaced, use pliers to pry the two ends of the cotter pin 405 back into place, pull the cotter pin 405 out of the hole of the bolt 402, release the lock on the nut 403, reverse the nut 403, and remove the nut 403 and the hexagonal protrusion 404. Thus, the bolt 402 is prevented from loosening by the cooperation of the cotter pin 405 and the hexagonal protrusion 404, and there is no need to re-drill holes in the reinforcing plate body 1 or replace the reinforcing plate body 1 for different hole spacing, which reduces the material cost of component replacement.
[0025] To mitigate the damage to the reinforcing plate body 1 caused by ground protrusions impacting it, such as... Figure 5 As shown, the impact-resistant mechanism 7 includes a trapezoidal mounting groove 701, a first steel plate 702, a positioning hole 703, an aluminum alloy honeycomb core 704, a positioning pin 705, and a second steel plate 706. The bottom of the reinforcing plate body 1 is provided with a trapezoidal mounting groove 701. The inner wall of the trapezoidal mounting groove 701 is welded with a first steel plate 702. The first steel plate 702 is provided with a positioning hole 703. The second steel plate 706 is welded to the inner wall of the trapezoidal mounting groove 701. The aluminum alloy honeycomb core 704 is placed between the second steel plate 706 and the first steel plate 702. A round hole is passed through the bottom of the aluminum alloy honeycomb core 704. The positioning pin 705 is welded to the top of the second steel plate 706. The other end of the positioning pin 705 is inserted into the positioning hole 703 and passes through the inner wall of the round hole in the aluminum alloy honeycomb core 704.
[0026] Steel plates 702 and 706 are completely fixed to the inner wall of the trapezoidal mounting groove 701, forming a closed chamber. The trapezoidal mounting groove 701 is located in the non-stress area of the reinforcing plate body 1. The aluminum alloy honeycomb core 704 is positioned using positioning holes 703 and positioning pins 705. The aluminum alloy honeycomb core 704 is clamped between steel plates 702 and 706. When the protrusion first impacts the outer surface of steel plate 706, steel plate 706 initially disperses the impact force through slight deformation, preventing the impact force from being directly concentrated at one point and transmitted to the aluminum alloy honeycomb core 704. The remaining impact force that is not dispersed is transmitted to the aluminum alloy honeycomb core 704. The porous thin-walled structure of 704 aluminum alloy honeycomb core undergoes deformation. The pore walls of the 704 aluminum alloy honeycomb core are compressed and folded, converting the kinetic energy generated by the impact into structural deformation. At the same time, the 704 aluminum alloy honeycomb core disperses the impact force in different directions. After the energy is absorbed by the 704 aluminum alloy honeycomb core, the impact force is finally transmitted to the inner walls of the steel plate 702 and the trapezoidal mounting groove 701. Thus, under the absorption of the impact force by the steel plate 706 and the 704 aluminum alloy honeycomb core, the damage to the main body 1 of the reinforcing plate is reduced under the same impact force. Meanwhile, the welded and sealed steel plate 706 protects the 704 aluminum alloy honeycomb core from dust and rainwater entering the 704 aluminum alloy honeycomb core and affecting its energy absorption effect.
[0027] Working principle: The nitrile rubber pad 5 is installed on the top of the reinforcing plate body 1 using screws 6 and annular grooves. The nitrile rubber pad 5 forms an elastic buffer layer between the reinforcing plate body 1 and the front auxiliary workshop to absorb the vibration energy during vehicle operation. Then, the ear plate 3 is installed at the end corner of the reinforcing plate body 1 through the parts replacement mechanism 4. If the ear plate 3 is worn or needs to be adapted to different hole spacing requirements, it can be replaced through the parts replacement mechanism 4. During vehicle operation, the impact-resistant mechanism 7 resists the impact of ground protrusions, thereby protecting the reinforcing plate body 1. Place the ear plate 3 to be installed into the mounting groove 401 at the end corner of the reinforcing plate body 1. Then, screw the shank of the bolt 402 into the threaded hole at the bottom of the mounting groove 401 and through the ear plate 3. Next, screw the nut 403 into the top of the bolt 402, while the hexagonal protrusion 404 moves synchronously until the nut 403 is flush against the top of the ear plate 3. Finally, pass one end of the cotter pin 405 through the gap between the protrusions of the hexagonal protrusion 404 and insert it into the pre-drilled hole on the outer surface of the bolt 402. Then, pry the two ends of the cotter pin 405 outwards so that the cotter pin 405 is flush against the outer surface of the hexagonal protrusion 404. When the ear plate 3 needs to be replaced, use pliers to reset the two ends of the cotter pin 405, pull the cotter pin 405 out of the hole of the bolt 402, release the lock on the nut 403, reverse the nut 403, and remove the nut 403 and the hexagonal protrusion 404. Steel plates 702 and 706 are completely fixed to the inner wall of the trapezoidal mounting groove 701, forming a closed chamber. The trapezoidal mounting groove 701 is located in the non-stress area of the reinforcing plate body 1. The aluminum alloy honeycomb core 704 is positioned by positioning holes 703 and positioning pins 705. The aluminum alloy honeycomb core 704 is clamped between steel plates 702 and 706. When the protrusion first impacts the outer surface of steel plate 706, steel plate 706 initially disperses the impact force through slight deformation. To avoid the impact force being directly concentrated at one point and transmitted to the aluminum alloy honeycomb core 704, the remaining impact force that is not dispersed is transmitted to the aluminum alloy honeycomb core 704. The porous thin-walled structure of the aluminum alloy honeycomb core 704 will deform, and the pore walls of the aluminum alloy honeycomb core 704 will be squeezed and folded, converting the kinetic energy generated by the impact into structural deformation. At the same time, the aluminum alloy honeycomb core 704 will disperse the impact force in different directions. After the energy is absorbed by the aluminum alloy honeycomb core 704, the impact force is finally transmitted to the inner wall of the steel plate 702 and the trapezoidal mounting groove 701.
