Description
Technical Field
[0001] This utility model relates to the field of automotive mounting plate technology, specifically an automotive mounting plate assembly with a buffer structure. Background Technology
[0002] A car mounting plate is a plate-shaped structural component used to fix various parts in a car. The anti-collision beam in the door panel is also fixed to the door using a mounting plate. The anti-collision beam is an important part of the safety structure of the car door. In some models, the rear door anti-collision beam is connected to the metal frame of the door through a mounting plate to ensure that the anti-collision beam is fixed in position inside the door. When the vehicle suffers a side collision, it can effectively absorb and disperse the impact energy and protect the safety of the occupants.
[0003] Existing car mounting plates are generally fixed to the anti-collision beam inside the rear door by welding or bolting. They generally withstand the impact force generated by the impact, and the buffering effect is generally limited. The anti-collision beam bears a lot of pressure and is prone to breakage. The impact resistance needs to be improved. Therefore, in order to address the above problems, a car mounting plate assembly with a buffer structure is proposed. Utility Model Content
[0004] The purpose of this invention is to provide an automotive mounting plate assembly with a buffer structure to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A car mounting plate assembly with a buffer structure includes a car door. A mounting plate is fixedly connected to the front side of the car door. A first connecting plate is fixedly connected to the front side of the mounting plate. An energy-absorbing vertical plate is fixedly connected to the front side of the first connecting plate. Two energy-absorbing vertical plates are fixedly connected to an energy-absorbing horizontal plate. A second connecting plate is fixedly connected to the side of the energy-absorbing vertical and horizontal plates away from the first connecting plate. A damper penetrating the first connecting plate, the energy-absorbing horizontal plate, and the second connecting plate is fixedly connected to the front side of the mounting plate. A shock-absorbing spring located outside the damper is fixedly connected to the front side of the second connecting plate. A support plate is fixedly connected to the front side of the damper and the shock-absorbing spring. A symmetrically arranged limiting groove is opened on the front side of the support plate. Limiting plates penetrating the limiting grooves are fixedly connected to both sides of the mounting plate. Limiting strips are fixedly connected to the front side of the limiting plates. A crash beam is fixedly connected to the front side of the support plate. A mounting shell located outside the crash beam is provided on the front side of the support plate. A rubber layer of the outer side of the crash beam is fixedly connected to the inner side of the mounting shell. A bolt penetrating the mounting shell is threaded into the inside of the support plate.
[0007] Preferably, there are several energy-absorbing vertical plates, and several energy-absorbing horizontal plates are fixedly connected between the energy-absorbing vertical plates. The energy-absorbing vertical plates and energy-absorbing horizontal plates are arranged in an alternating manner between the first connecting plate and the second connecting plate.
[0008] Preferably, the damper and the shock-absorbing spring are in a group, and there are several groups in total. The damper and the shock-absorbing spring are evenly distributed in a matrix between the fixed plate and the support plate.
[0009] Preferably, the shape of the anti-collision beam matches the inner shape of the rubber layer, both being X-shaped, and the size of the anti-collision beam matches the inner size of the rubber layer.
[0010] Preferably, there are four bolts, which are arranged symmetrically inside the support plate.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. In this utility model, the fixed plate, first connecting plate, energy-absorbing vertical plate, energy-absorbing horizontal plate, second connecting plate, damper, shock-absorbing spring and rubber layer are set up. The rubber layer can initially reduce the impact force of external impact on the anti-collision beam. The damper and shock-absorbing spring absorb the kinetic energy generated by the impact. The first connecting plate, energy-absorbing vertical plate, energy-absorbing horizontal plate and second connecting plate further provide rearward buffer for the anti-collision beam through their own collapse and absorb the impact force generated by the impact. The multiple sets of buffer structures effectively distribute the pressure on the anti-collision beam, thereby solving the problem that the existing car fixed plates are generally fixed to the anti-collision beam in the rear door by welding or bolts. Generally, they resist the impact force generated by the impact, the buffering effect is generally average, the anti-collision beam bears a lot of pressure, and there is a risk of breakage. The anti-collision capability needs to be improved.
[0013] 2. In this utility model, when subjected to minor impact, the fixing shell and rubber layer can be removed by unscrewing the bolts, and the fixing shell and rubber layer can be replaced as a whole to ensure the fixing effect of the fixing shell on the rubber layer.

[0022] Please see Figure 1-4 This utility model provides a technical solution:
[0023] A car mounting plate assembly with a buffer structure includes a car door 1. A mounting plate 2 is fixedly connected to the front side of the car door 1. A first connecting plate 3 is fixedly connected to the front side of the mounting plate 2. An energy-absorbing vertical plate 4 is fixedly connected to the front side of the first connecting plate 3. An energy-absorbing horizontal plate 5 is fixedly connected to the two energy-absorbing vertical plates 4. A second connecting plate 6 is fixedly connected to the side of the energy-absorbing vertical plates 4 and the energy-absorbing horizontal plate 5 away from the first connecting plate 3. A damper 7 is fixedly connected to the front side of the mounting plate 2, penetrating the first connecting plate 3, the energy-absorbing horizontal plate 5, and the second connecting plate 6. A device located outside the damper 7 is fixedly connected to the front side of the second connecting plate 6. The front side of the shock absorber spring 8, the damper 7, and the shock absorber spring 8 are fixedly connected to the support plate 9. The front side of the support plate 9 is provided with symmetrically arranged limiting grooves 10. The two sides of the fixed plate 2 are fixedly connected with limiting plates 11 that penetrate the limiting grooves 10. The front side of the limiting plate 11 is fixedly connected with a limiting strip 12. The front side of the support plate 9 is fixedly connected with a crash beam 13. The front side of the support plate 9 is provided with a fixed shell 14 located outside the crash beam 13. The inner side of the fixed shell 14 is fixedly connected with a rubber layer 15 outside the crash beam 13. The internal thread of the support plate 9 is connected with a bolt 16 that penetrates the fixed shell 14.
[0024] There are several energy-absorbing vertical plates 4, and several energy-absorbing horizontal plates 5 are fixedly connected between the energy-absorbing vertical plates 4. The energy-absorbing vertical plates 4 and energy-absorbing horizontal plates 5 are arranged in an alternating manner between the first connecting plate 3 and the second connecting plate 6. Through the hollow structure of the alternating energy-absorbing vertical plates 4 and energy-absorbing horizontal plates 5, they can better achieve self-collapse and energy absorption effect. The dampers 7 and shock-absorbing springs 8 are a group, and there are several groups in total. The dampers 7 and shock-absorbing springs 8 are evenly distributed in a matrix between the fixed plate 2 and the support plate 9. The multiple groups of dampers 7 and shock-absorbing springs 8 can more evenly absorb the impact force generated by the impact. The shape of the anti-collision beam 13 matches the inner shape of the rubber layer 15, both being X-shaped. The size of the anti-collision beam 13 matches the inner size of the rubber layer 15, which can better wrap and protect the anti-collision beam 13 through the rubber layer 15. There are four bolts 16, which are symmetrically arranged inside the support plate 9.
[0025] Workflow: When a car mounting plate assembly with a buffer structure is required, upon impact, the rubber layer 15 provides initial buffering, reducing the impact force of the external impact on the anti-collision beam 13. The impact on the anti-collision beam 13 causes the support plate 9 to move rearward under the guidance of the limiting groove 10 and the limiting plate 11. The support plate 9 compresses the damper 7 and the shock-absorbing spring 8, absorbing the kinetic energy generated by the impact. The first connecting plate 3, energy-absorbing vertical plate 4, energy-absorbing horizontal plate 5, and second connecting plate 6, upon impact, further provide rearward buffering for the anti-collision beam 13 through their own collapse, absorbing the impact force. The multiple buffer structures effectively distribute the pressure on the anti-collision beam 13, minimizing the risk of direct breakage.
