Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Hereinafter, a vehicle chassis and a vehicle according to an embodiment of the present invention will be described in detail with reference to fig. 1 to 5.

According to the utility model discloses a vehicle chassis can include: a longitudinal beam 10 provided along a longitudinal direction of a vehicle chassis; a crush zone 20, a first end 21 of the crush zone 20 being joined to the first end 11 of the side member 10 in the lengthwise direction; front wheels 30 disposed on both sides of the crush zone 20 in the width direction of the vehicle chassis and connected to the crush zone 20; and guide regions 40, the guide regions 40 being fixed to both sides of the side member 10 in the width direction at positions of the side member 10 near the crush region 20, and the guide regions 40 being configured such that when the crush region 20 is crushed, the crush region 20 is fitted over the guide regions 40, so that the front wheel 30 is deflected.

According to an embodiment of the present invention, as shown in fig. 1, a vehicle chassis may include a longitudinal beam 10 and a crush zone 20.

The longitudinal member 10 may be disposed along the length of the vehicle chassis. The first end 21 of the crush zone 20 is bonded lengthwise to the first end 11 of the stringer 10. The crush zone 20 collapses to absorb stress when the vehicle is impacted. The structural strength of the crush zone 20 is less than the structural strength of the stringer 10. As an example, the material of the crush zone 20 may be less strong than the material of the stringer 10. As another example, the side member 10 and the crush zone 20 are formed of the same material, and a crush structure (e.g., a crush hole) is formed on the crush zone 20 so that the structural strength thereof is smaller than that of the side member 10. In this case, the side member 10 and the crush zone 20 may be integrally formed, and distinguished only by the purpose. However, the specific structure of the stringer 10 and the crush zone 20 according to an embodiment of the present invention is not limited thereto, and any type of stringer 10 and crush zone 20 known in the art may be used.

As shown in fig. 1, the vehicle chassis may further include front wheels 30, the front wheels 30 being disposed on both sides of the crush zone 20 in the width direction of the vehicle chassis and being connectable to the crush zone 20. Specifically, the vehicle chassis may further include front suspension fork arms 60, the front suspension fork arms 60 being disposed on both sides of the crush zone 20 in the width direction of the vehicle chassis and may connect the crush zone 20 and the front wheel 30 to each other. The specific structure of front suspension fork arm 60 and the manner of connection to crush zone 20 and front wheel 30 are not particularly limited, and any structure and any manner of connection known in the art may be used.

As shown in fig. 1, the vehicle chassis may further include a cross member 50, and the cross member 50 may be disposed in the width direction of the vehicle chassis and may be connected to the side members 10. The specific structure of the cross member 50 is not particularly limited, but any structure known in the art may be applied.

As shown in fig. 1, the vehicle chassis may also include an impact beam 70, the impact beam 70 coupled to a second end of the crush zone 20 opposite the first end 21. The specific structure of the impact beam 70 is not particularly limited, and any structure known in the art may be applied.

Further, although not shown in fig. 1, the vehicle chassis may further include shock absorbers, a steering gear, and a steering rod, which are not described one by one.

As shown in fig. 1, when an impact is applied, the impact beam 70 pushes the crush zone 20 to collapse, thereby absorbing the impact energy and preventing the energy from being directly transmitted to the cabin to cause injury to the occupants. In the prior art, when a vehicle collides with an obstacle in the front, the front wheels can be directly clamped between the obstacle and a vehicle body frame or a vehicle door, so that the crumple zone cannot be deformed sufficiently to play a buffering role, the collision between the vehicle and the obstacle is close to rigid collision, and great personal injury is caused to drivers and passengers.

In addition, the front wheels may crush the door of the cab during a collision, so that the door is severely deformed and cannot be opened, thereby causing great inconvenience to rescue passengers, and thus valuable time for treating the wounded is lost.

To solve the above problem, as shown in fig. 1, the vehicle chassis according to an embodiment of the present invention may further include a guide zone 40. The guide regions 40 are fixed to both sides of the side member 10 in the width direction at a position of the side member 10 near the crush region 20, and the guide regions 40 are configured such that when the crush region 20 is crushed, the crush region 20 can be fitted over the guide regions 40 so that the front wheel 30 is deflected.

Specifically, two guide areas 40 may be provided symmetrically on both sides in the width direction of the side member 10. The width of the guide zone 40 gradually increases in the lengthwise direction of the vehicle chassis, in a direction away from the crush zone 20. That is, the outer side surface of the guide section 40 may form an inclined surface.

As shown in fig. 5, when the vehicle collides with an obstacle, the crush zone 20 is crushed toward the rear of the vehicle due to the collision, the connection between the crush zone 20 and the front end of the side member 10 is loosened by the strong impact force, the mounting point 61 (specifically, the rear mounting point 61) of the front suspension fork arm 60 is first guided to the guide wall 42 of the guide zone 40, and the entire front suspension fork arm 60 slides toward the rear of the vehicle under the guidance of the guide wall 42 of the guide zone 40. The front suspension fork arm 60 thus disposed on the crush zone 20 is tilted by moving rearward of the vehicle along the guide wall 42 of the guide zone 40 together with the crush zone 20. The front wheel 30 deflects under the extrusion of the obstacle, so that the front wheel 30 is not extruded on the obstacle and the vehicle body frame or the vehicle door, namely the diameter of the tire between the obstacle and the vehicle body frame or the vehicle door is shortened, thus the collapsing distance of the collapsing area 20 is increased, the huge energy generated in the collision can be better absorbed, and the life safety of a driver can be protected. In addition, due to the guiding function of the guide wall 42 of the guide area 40, the front suspension fork arm 60 inclines towards the front of the vehicle, the rear part of the front wheel 30 deflects towards the direction away from the longitudinal beam 10 after the front suspension fork arm strikes an obstacle, the phenomenon that the front wheel 30 presses the door can be reduced, and therefore the door can be opened easily when a traffic accident happens, and passengers in the vehicle can be rescued from the vehicle quickly.

Hereinafter, the guide area 40 according to an embodiment of the present invention is described in detail with reference to fig. 2 to 4.

As shown in fig. 2, the guide region 40 includes a first fixing wall 41 fixed to the side member 10 and a guide wall (i.e., the above-described inclined surface) 42 extending obliquely from a front end 41a of the first fixing wall 41 toward a direction away from the crush region 20. The width between the first fixing wall 41 and the guide wall 42 in the width direction gradually increases from the front end 41a of the first fixing wall 41 to the rear end 41b of the first fixing wall 41 in the length direction. Although fig. 2 shows the guide wall 42 as a planar shape, the present invention is not limited thereto, and the guide wall 42 may be an inclined curved surface or an arc surface.

As shown in fig. 2, according to an embodiment of the present invention, the guide area 40 may further include a second fixing wall 43 connecting the first fixing wall 41 and the guide wall 42. The second fixing wall 43 may be fixed to other parts of the vehicle chassis. As an example, the second fixing wall 43 may be fixed to the cross member 50. However, the present invention is not limited thereto.

As shown in fig. 2, according to an embodiment of the present invention, the guiding region 40 may further include an upper end wall 44 and a lower end wall 45. The upper end wall 44 and the lower end wall 45 may be opposed to each other in the height direction of the vehicle chassis. In addition, the upper end wall 44 and the lower end wall 45 connect the first fixing wall 41, the guide wall 42, and the second fixing wall 43 to each other, forming an approximately wedge-shaped pentahedral shape.

According to an embodiment of the present invention, as shown in fig. 3 and 4, the front end 41a of the first fixing wall 41 may be disposed to be spaced apart from the first end 11 of the longitudinal beam 10. That is, the front end 41a of the first fixing wall 41 is displaced rearward from the first end 11 of the side member 10 by a distance.

However, the present invention is not limited thereto, and the front end 41a of the first fixing wall 41 may be disposed flush with the first end 11 of the side member 10. That is, the front end 41a of the first fixing wall 41 may extend up to the intersection between the side member 10 and the crush zone 20, and the guide wall 42 extends obliquely from the intersection between the side member 10 and the crush zone 20.

Fig. 3 and 4 show two configurations of the vehicle chassis when the front end 41a of the first fixing wall 41 is disposed spaced apart from the first end 11 of the side member 10, respectively.

As shown in fig. 3, as an embodiment of the present invention, when the front end 41a of the first fixing wall 41 is disposed to be spaced apart from the first end 11 of the side member 10, the vehicle chassis may further include a transition region 40a fixed to the side member 10 and the guide wall 42, the transition region 40a extending obliquely from both sides of the first end 21 of the crush zone 20 to the guide wall 42. According to an embodiment of the present invention, the transition from the crush zone 20 and the longitudinal beam 10 to the guide zone 40 can be made smooth by providing the guide wall 42. Therefore, when the crush zone 20 is collapsed, the crush zone 20 can smoothly slide along the guide wall 42 and fit over the guide zone 40.

According to an embodiment of the present invention, the length of the transition area 40a extending on the guide wall 42 is not particularly limited. In addition, according to an embodiment of the present invention, the outer side surface (or referred to as a transition surface) of the transition region 40a may also be formed as an arc surface, not limited to the plane shown in fig. 3.

As shown in fig. 4, as another embodiment of the present invention, when the front end 41a of the first fixing wall 41 is disposed to be spaced apart from the first end 11 of the side member 10, the side member 10 may include a guide portion 12, and the guide portion 12 may be obliquely extended to the first end 21 of the crush zone 20 from the intersection of the guide wall 42 and the first fixing wall 41 (i.e., at the front end 41a of the first fixing wall 41). According to the embodiment of the present invention, when the crush zone 20 is collapsed, the deformed crush zone 20 can be easily fitted over the guide zone 40 along the guide portion 12.

According to an embodiment of the present invention, the inclination angle of the guide portion 12 may be the same as the inclination angle of the guide wall 42. However, the present invention is not limited thereto, and the inclination angle of the guide portion 12 may be different from the inclination angle of the guide wall 42.

According to an embodiment of the invention, the upper end wall 44 and the lower end wall 45 of the guiding zone 40 may be substantially flush with the upper end and the lower end of the longitudinal beam 10 in the height direction, respectively. However, the present invention is not limited to this, as long as the crush zone 20 can be fitted over the guide zone 40 to deflect the front wheel 30 when the crush zone is in the collapsed state. As an example, the upper end wall 44 of the guide zone 40 may be disposed lower than the upper end of the longitudinal beam 10, and the lower end wall 45 of the guide zone 40 may be disposed higher than the lower end of the longitudinal beam 10. That is, the height of the guide area 40 in the height direction of the vehicle chassis may be smaller than the height of the side member 10 in the height direction.

According to another embodiment of the present invention, there may also be provided a vehicle including the vehicle chassis described above.

As described above, according to the vehicle chassis of the embodiment of the present invention, it is possible to avoid a rigid collision of the vehicle with the obstacle due to the extrusion of the front wheels between the obstacle and the body frame.

Additionally, according to the utility model discloses a vehicle chassis, can avoid the front wheel to the door extrusion phenomenon's of driver's cabin emergence, the door still can be relatively easy when taking place the traffic accident open for the passenger can be rescued out from the vehicle fast.

Although the exemplary embodiments of the present invention have been described with reference to the accompanying drawings, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
