Description

Technical Field

[0001] The utility model belongs to the technical field of new energy vehicle body structure design, and particularly relates to a front cabin reinforcement structure and a vehicle. Background Art

[0002] Front cabin torsional stiffness, front shock absorber mounting point dynamic stiffness, and crashworthiness are important indicators of vehicle performance. Body stiffness and front shock absorber mounting point dynamic stiffness are key factors influencing vehicle safety and handling. Traditional front cabin structural designs lack these characteristics, making them inadequate for meeting the performance requirements of modern new energy vehicles.

[0003] The traditional front cabin structure has a single design form, discrete components, and complex connections, which increases the weight of the vehicle body and reduces the overall rigidity. In addition, the integration between the components is not high, resulting in the overall structure being not compact enough and making it difficult to form an effective rigid structural system.

[0004] When the dynamic stiffness of the front shock absorber installation point is insufficient, the vertical bounce range of the wheel may increase when the vehicle is turning or driving at high speed, resulting in excessive body roll angle, affecting the vehicle's handling stability; it may also cause instability in the vehicle's driving direction, especially on uneven roads or when changing lanes urgently, the direction deviation phenomenon is more obvious. Summary of the invention

[0005] The purpose of the present utility model is to overcome the above-mentioned problems and provide a front cabin reinforcement structure and a car, which can improve the torsional stiffness of the front cabin of the car body, the dynamic stiffness of the front shock absorber installation and the collision force transmission path, thereby improving the safety performance and handling performance of the vehicle.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The utility model provides a front cabin reinforcement structure, comprising a support connecting plate and a heat pump crossbeam, wherein the support connecting plate comprises a left support connecting plate and a right support connecting plate, and the left support connecting plate and the right support connecting plate are distributed in an inverted figure eight shape at the front part of the front cabin of the body-in-white;

[0018] The present utility model also provides an automobile, including the front compartment strengthening structure described in any one of the above.

[0019] Compared with the prior art, the present utility model has the following beneficial effects:

[0020] The utility model fixes and connects the left support connecting plate and the right support connecting plate to the front part of the front cabin of the body-in-white in an inverted "V" layout.

[0036] The following further describes the present invention in detail with reference to the accompanying drawings:

[0037] Embodiment

[0038] Combined with what is mentioned in the background art, there are currently some problems with the front cabin reinforcement structure. For example: the traditional front cabin structure design form is single, and the integration degree between components is not high, resulting in an insufficiently compact overall structure and affecting the handling stability of the vehicle. Therefore, it is necessary to find a new structure to solve this problem.

[0039] To solve the above technical problems, an embodiment of the present invention provides a front cabin reinforcement structure and an automobile.

[0040] As Figure 1 shown, this embodiment provides a front cabin reinforcement structure, including a support connection plate and a heat pump cross beam 5. The support connection plate includes a left support connection plate 1 and a right support connection plate 2. The left support connection plate 1 and the right support connection plate 2 are distributed in an inverted V shape at the front of the white body front cabin. The front of the white vehicle front cabin includes a front wheelhouse side reinforcement beam, a front shock absorber mounting seat, and a front end frame upper cross beam 6. The left support connection plate 1 and the right support connection plate 2 connect the front wheelhouse side reinforcement beam and the front end frame upper cross beam 6. The heat pump cross beam 5 is connected to the front shock absorber mounting seat. This inverted V-shaped layout enhances the overall rigidity of the front cabin structure, reduces the deformation and vibration of the vehicle during driving, improves the stability and handling performance of the vehicle, and the enhanced front cabin structure can better support the heat pump cross beam 5 to ensure its stable posture during vehicle driving.

[0041] In this embodiment, the front end of the front part of the white body front cabin is welded and fixed to the front end frame upper cross beam 6. The welding and fixing of the front end frame upper cross beam 6 can significantly enhance the overall rigidity of the front part of the white body front cabin. This improvement in rigidity helps to reduce the torsional deformation of the vehicle during driving and improve the stability and handling performance of the vehicle.

[0042] In this embodiment, the front wheelhouse side reinforcing beam includes a left front wheelhouse side reinforcing beam 3 and a right front wheelhouse side reinforcing beam 4. The left front wheelhouse side reinforcing beam 3 and the right front wheelhouse side reinforcing beam 4 are welded and fixed on the left and right sides of the front part of the body-in-white front compartment, strengthening the support structure of the front wheelhouse area. This design can provide additional protection for the front wheelhouse area when the vehicle undergoes a side collision or rollover, reducing body deformation and occupant injury caused by the collision.

[0043] In this embodiment, the front shock absorber mounting seat includes a left front shock absorber mounting seat 7 and a right front shock absorber mounting seat 8. The left front shock absorber mounting seat 7 and the right front shock absorber mounting seat 8 are respectively connected to the left front wheelhouse side reinforcing beam 3 and the right front wheelhouse side reinforcing beam 4. The heat pump crossbeam 5 is bolted to the left front shock absorber mounting seat 7 and the right front shock absorber mounting seat 8 through the fifth bolt holes 52. This bolt connection method has high strength and stability, which can ensure that the heat pump crossbeam 5 maintains a stable posture during vehicle driving, avoiding loosening or falling off caused by vibration or bump.

[0044] In this embodiment, as Figure 2 shown, both ends of the left support connecting plate 1 are respectively provided with a first bolt hole 11 and a second bolt hole 12, which can achieve multi-point fixation. This multi-point fixation method can disperse the force at the connection points, avoiding loosening or damage of the connection caused by excessive force at a single point, thereby enhancing the stability of the connection.

[0045] In this embodiment, as Figure 3 shown, both ends of the right support connecting plate 2 are respectively provided with a third bolt hole 21 and a fourth bolt hole 22. Through the design of the two bolt holes, the strength of the connection point can be further improved. During the assembly process, only need to pass the bolts through the corresponding bolt holes and tighten them to achieve a firm connection.

[0046] In this embodiment, as Figure 4 shown, the heat pump crossbeam 5 is provided with supports 51 at both ends, and fifth bolt holes 52 are opened at the ends of the supports 51. By opening the fifth bolt holes 52 at the ends of the supports 51, it is convenient to use bolts to tightly connect the supports 51 to the heat pump crossbeam 5.

[0047] Next, the present utility model will be further explained and illustrated in combination with a set of examples and drawings:

[0048] As Figure 1 , Figure 2 and Figure 3 shown, the left support connecting plate 1 is bolted to the front end frame upper crossbeam 6 through the first bolt hole 11, the left support connecting plate 1 is bolted to the left front wheelhouse side reinforcing beam 3 through the second bolt hole 12, the right support connecting plate 2 is bolted to the front end frame upper crossbeam 6 through the third bolt hole 21, and the right support connecting plate 2 is bolted to the right front wheelhouse side reinforcing beam 4 through the fourth bolt hole 22.

[0049] For another example Figure 2 and Figure 3 As shown, both the left support connecting plate 1 and the right support connecting plate 2 are made of steel. The support connecting plate made of steel can bear a large load, ensuring the stability and safety of the structure. At the same time, it can share and transfer the load in the structure, avoiding structural damage caused by excessive load.

[0050] Such as Figure 4 As shown, the heat pump crossbeam 5 is bolted to the left front shock absorber mounting seat 7 and the right front shock absorber mounting seat 8 through the fifth bolt hole 52. Bolt connection has good anti-vibration performance and can bear a certain degree of vibration and impact load, further improving the strength and stiffness of the connection, and ensuring the stability and safety of the heat pump crossbeam 5 during vehicle driving.

[0051] In summary, this embodiment provides an inverted V-shaped front cabin reinforcement structure, which not only significantly enhances the rigidity and stability of the front cabin area, effectively improves the safety of the vehicle in the event of a collision, but also ensures the firm connection between components through elaborate bolt hole design and multi-point fixing method, simplifies the installation process, facilitates subsequent maintenance and adjustment, thereby further improving the safety performance and handling performance of the vehicle.

[0052] This embodiment also provides an automobile with a front cabin reinforcement structure. This automobile adopts a front cabin reinforcement structure. When the automobile collides, the front cabin reinforcement structure can absorb and disperse the collision energy, ensuring the stable posture of the heat pump crossbeam during vehicle driving, helping to reduce the energy loss caused by collision or vibration, enabling the vehicle's power system to transmit power more effectively, improving the vehicle's acceleration performance and fuel economy. At the same time, the strengthened front cabin structure improves the rigidity of the vehicle, helping to improve the vehicle's handling performance and making driving more stable and safe.
