Description

Technical Field

[0001] The embodiments of the present application relate to the field of vehicle technology, and in particular to a vehicle body pillar inner panel structure and a vehicle. Background Art

[0002] The body pillar is one of the key structures in the body structure, which plays a role in improving the load-bearing capacity and stability of key parts of the vehicle. Taking the A-pillar as an example, the A-pillar is located between the engine compartment and the passenger compartment, that is, the pillars on both sides of the front windshield, mainly connecting the roof and the engine compartment, and plays a role in the stability of the body structure. The inner plate of the A-pillar is usually connected to the A-pillar to strengthen the load-bearing capacity and stability of key parts such as the A-pillar, thereby improving the overall rigidity and safety of the vehicle.

[0003] In the prior art, in order to make the inner panel of the vehicle body pillar have sufficient supporting strength, it is usually necessary to thicken the inner panel of the vehicle body pillar to improve the overall structural strength of the inner panel of the vehicle body pillar so as to meet the strength requirements of the vehicle body.

[0004] However, for the above-mentioned body pillar inner panel structure, in models such as new energy vehicles that are sensitive to the weight of the entire vehicle, increasing the thickness of the body pillar inner panel will significantly increase the weight of the entire vehicle, while correspondingly reducing the thickness of the body pillar inner panel will easily weaken the body strength, resulting in excessive deformation in local areas during vehicle collision safety analysis. Utility Model Content

[0005] In view of this, the embodiments of the present application provide a body pillar inner panel structure and a vehicle, which improves the structural strength and stability of the body pillar inner panel while controlling the weight of the vehicle by changing the structure of the body pillar inner panel and other components.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the embodiment of the present application is implemented as follows:

[0008] An embodiment of the present application provides an inner panel structure of a vehicle body pillar, wherein the panel body is connected to the collision energy absorbing structure of the vehicle, and a first reinforcement portion is arranged at a position opposite to the collision energy absorbing structure, so as to strengthen the local structure of the panel body in a targeted manner. When impacted, the panel body transmits the impact force to the collision energy absorbing structure, and the collision energy absorbing structure absorbs the impact force. At the same time, the first reinforcement portion itself strengthens the panel body structure and reduces the deformation of the panel body structure. While ensuring the strength of the panel body structure, the weight is also reduced, thereby meeting the lightweight requirements of the vehicle. In addition, since the first reinforcement portion and the collision energy absorbing structure are arranged on different sides of the panel body, the first reinforcement portion will not affect the firmness of the connection between the panel body and the collision energy absorbing structure, thereby avoiding the situation in which the inner panel and the collision energy absorbing structure are separated when impacted, resulting in the collision energy absorbing structure being unable to smoothly absorb the impact force.

[0009] In a possible implementation of the present application, the first reinforcement portion includes at least two first sub-reinforcement plates, and the at least two first sub-reinforcement plates are stacked, and in a direction away from the plate body, sizes of the sub-reinforcement plates are the same or gradually decrease.

[0011] In a possible implementation of the present application, the second reinforcement portion includes at least two second sub-reinforcement plates, and the at least two second sub-reinforcement plates are stacked, and in a direction away from the plate body, sizes of the sub-reinforcement plates are the same or gradually decrease.

[0012] In a possible implementation of the present application, the first mounting surface is connected to the steering support assembly of the vehicle body, and a third reinforcement portion is provided on the second mounting surface, and the third reinforcement portion is arranged opposite to the steering support assembly connection portion.

[0013] In a possible implementation of the present application, the third reinforcement portion includes at least two third sub-reinforcement plates, and the at least two third sub-reinforcement plates are stacked, and in a direction away from the plate body, the sub-reinforcement plates have the same size or gradually decrease in size.

[0014] In a possible implementation of the present application, the thickness of the first reinforcing part, the second reinforcing part and the third reinforcing part are respectively greater than or equal to 0.5 times the thickness of the plate body at their locations, and less than or equal to 3 times the thickness of the plate body at their locations.

[0015] In a possible implementation of the present application, the first reinforcement portion, the second reinforcement portion and the third reinforcement portion are respectively formed integrally with the plate body.

[0016] In a second aspect, an embodiment of the present application provides a vehicle, comprising: a vehicle body; an engine side beam; a collision energy absorbing structure, a first end of which is connected to the first mounting surface, and a second end of which is connected to the engine side beam of the vehicle body; the above-mentioned vehicle body pillar inner panel structure, the first mounting surface is connected to the first end of the collision energy absorbing structure, and the first reinforcement portion is arranged opposite to the first end of the collision energy absorbing structure.

[0017] The vehicle provided in the embodiment of the present application adopts the above-mentioned vehicle body pillar inner panel structure, which locally enhances the strength of the inner panel in a targeted manner, controls the deformation of the inner panel and does not affect the connection stability of the inner panel with other structures, and has good structural reliability. In addition, since the two ends of the collision energy absorption structure are respectively connected to the engine side beam and the inner panel, when the inner panel is impacted, the impact force is transmitted to the collision energy absorption structure and absorbed by the collision energy absorption structure. At the same time, the collision energy absorption structure is connected to the end of the engine side beam, which controls the total deformation and further reduces the situation where the collision energy absorption structure is separated from the vehicle when impacted, thereby improving the structural rigidity and reliability.

DETAILED DESCRIPTION

The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they may change accordingly according to the changes in the orientation of the components in the drawings.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0029] In the embodiments of the present application, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0030] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0031] The present application embodiment provides a vehicle, see Figure 4 It should be noted that the vehicle in this application may refer to a large car, a small car, a special-purpose car, etc. For example, according to the model, the car in this application may be a sedan model, an off-road model, a multi-purpose vehicle (MPV) model or other models. For a vehicle, it generally has a body, an engine side beam 500, a steering support assembly and an engine side beam 500. The engine side beam 500, the steering support assembly and the engine side beam 500 are all arranged on the body, and all have the function of strengthening the strength of the body structure. The body is provided with a body column and a body column inner plate structure connected to the body column. The body column includes an A column, a B column and a C column. The corresponding body column inner plates are respectively arranged at different parts of the vehicle, which are used to strengthen the body structure and ensure the safety of the driver and passengers. Taking the A column as an example, the A column is an inclined column arranged between the front door glass of the cockpit and the engine compartment, which is used to strengthen the vehicle structure and ensure the safety of the driver and passengers. The A column inner plate is located at the lower side of the A column to provide support for the A column.

[0032] Specifically, the engine side beam 500 is arranged at the bottom of the vehicle body and fixedly connected to the vehicle body. It is the main structural member that provides rigidity for the vehicle as a whole and has high strength. The collision energy absorption structure 200 is used to absorb impact force and absorb energy when the vehicle collides to improve the safety of the driver and passengers. One end of the collision energy absorption structure 200 is connected to the inner plate structure of the vehicle body pillar, and the other end is connected to the engine side beam 500.

[0033] Specifically, the steering support assembly is arranged at the front side of the vehicle cab, and its two ends are respectively connected to the inner plate of the body pillar to provide support for the vehicle instrument panel assembly. The fender assembly 300 is arranged on one side of the vehicle and connected to the inner plate of the body pillar. A front wheel bulge 700 is arranged between the fender and the engine side beam 500. The front wheel bulge 700 is formed by the body making way for the front wheel. The fender is connected to the engine side beam 500 through the front wheel bulge 700, which improves the anti-deformation ability of the fender and transmits the external force from the inner plate of the body pillar to the engine side beam 500. At the same time, a shock absorber can be arranged on the front wheel bulge 700 to absorb the impact force.

[0034] In the vehicle provided in the embodiment of the present application, since the two ends of the collision energy absorbing structure 200 are respectively connected to the engine side beam 500 and the inner panel, when the inner panel receives an impact, the impact force is transmitted to the collision energy absorbing structure 200 and absorbed by the collision energy absorbing structure 200. At the same time, the collision energy absorbing structure 200 abuts against the end of the engine side beam 500, thereby controlling the total deformation and further reducing the possibility of the collision energy absorbing structure 200 being detached from the vehicle when impacted, thereby improving the structural rigidity and reliability.

[0035] On this basis, refer to Figure 1 and Figure 4 The embodiment of the present application also provides a vehicle body pillar inner panel structure, including: a panel body 100, having a first mounting surface 101 and a second mounting surface 102 which are arranged opposite to each other, the first mounting surface 101 facing the inner side of the vehicle, the second mounting surface 102 facing the outer side of the vehicle, and the first mounting surface 101 being connected to the collision energy absorbing structure 200 of the vehicle body; a first reinforcement portion 601, the first reinforcement portion 601 being arranged on the second mounting surface 102, and the first reinforcement portion 601 being arranged opposite to the end of the collision energy absorbing structure 200.

[0036] In this embodiment, the plate body 100 is connected to the collision energy absorbing structure 200 of the vehicle, and a first reinforcement portion 601 is provided at a position opposite to the collision energy absorbing structure 200, so as to strengthen the local structure of the plate body 100 in a targeted manner. When impacted, the plate body 100 transmits the impact force to the collision energy absorbing structure 200, and the collision energy absorbing structure 200 absorbs the impact force. At the same time, the first reinforcement portion 601 itself strengthens the structure of the plate body 100 and reduces the deformation of the structure of the plate body 100. While ensuring the structural strength of the plate body 100, the weight is also reduced, thereby meeting the lightweight requirements of the vehicle. In addition, since the first reinforcement portion 601 and the collision energy absorbing structure 200 are arranged on different sides of the plate body 100, the first reinforcement portion 601 will not affect the firmness of the connection between the plate body 100 and the collision energy absorbing structure 200, thereby avoiding the situation in which the inner panel and the collision energy absorbing structure 200 are separated when impacted, resulting in the collision energy absorbing structure 200 being unable to smoothly absorb the impact force.

[0037] Specifically, the first mounting surface 101 and the second mounting surface 102 may be a plane, or a curved surface or an irregular surface. It should be noted that the embodiment of the present application does not limit the specific form of the first reinforcing portion 601, and it is sufficient that it can strengthen the structure of the inner plate of the vehicle body pillar. Exemplarily, the first reinforcing portion 601 may be a plate-shaped member, and in some embodiments not shown, the first reinforcing portion 601 may also be a strip-shaped member or a member of other shapes.

[0038] It should be noted that the first reinforcement portion 601 and the end of the collision energy absorbing structure 200 are arranged relative to each other, and can be completely opposite to each other or partially opposite to each other, wherein "partially opposite to each other" means that the area where the first reinforcement portion 601 is connected to the plate body 100 partially overlaps with the area where the collision energy absorbing structure 200 is connected to the plate body 100.

[0039] In one embodiment, see Figure 2 and Figure 3 The first reinforcing portion 601 includes at least two first sub-reinforcing plates 6011 , and the at least two first sub-reinforcing plates 6011 are stacked and arranged, and in the direction away from the plate body 100 , the sizes of the sub-reinforcing plates are the same or gradually decrease.

[0040] Specifically, the stacking method of the plurality of first sub-reinforcement plates 6011 is not limited in the embodiment of the present application. The plurality of first sub-reinforcement plates 6011 can be stacked in a manner of maintaining center alignment or can be stacked eccentrically. At the same time, the specific shape of the first sub-reinforcement plates 6011 is not limited in the embodiment of the present application. The first sub-reinforcement plates 6011 can be square plate-shaped members. In some embodiments not shown, the first sub-reinforcement plates 6011 can also be circular plate-shaped members or curved panels with curved surfaces.

[0041] It should be noted that the embodiment of the present application does not limit the connection method between multiple first sub-reinforcement plates 6011, or the connection method between the first sub-reinforcement plates 6011 and the plate body 100. The first sub-reinforcement plates 6011 and the first sub-reinforcement plates 6011 and the plate body 100 can be connected by fasteners such as bolts and screws, can be connected by welding, or can be connected by one-piece molding.

[0042] In this embodiment, multiple first sub-reinforcement plates 6011 are stacked and arranged such that the sizes of the first sub-reinforcement plates 6011 are the same or reduced in the direction away from the plate body 100, which can further specifically enhance the local strength of the plate body 100. At the same time, it also avoids the situation in which the overall weight of the vehicle is greatly affected by increasing the thickness of the first reinforcement part 601.

[0043] The following takes the A-pillar inner panel as an example to further describe the vehicle inner panel structure.

[0044] In one embodiment, when the plate body is connected to the A-pillar of the vehicle body, that is, the plate body is the inner panel of the A-pillar, the second mounting surface 102 is connected to the fender assembly 300 of the vehicle body, and a second reinforcement portion 602 is provided at the connection between the second mounting surface 102 and the fender.

[0045] The embodiment of the present application does not limit the specific form of the second reinforcement part 602, and it only needs to strengthen the structure of the inner plate of the vehicle body pillar. For example, the second reinforcement part 602 can be a plate-shaped part. In some embodiments not shown, the second reinforcement part 602 can also be a strip-shaped part or a part of other shapes.

[0046] In this embodiment, the connection between the second mounting surface 102 and the fender assembly 300 facilitates the transmission of force between the fender assembly 300 and the plate body 100, thereby improving the structural strength of the inner plate of the vehicle body pillar and the fender assembly 300. By providing a second reinforcement portion 602 at the connection and making the second reinforcement portion 602 face the end of the fender assembly 300, the structural strength of the plate body 100 is specifically enhanced at the connection of the fender assembly 300, thereby further reducing the possibility that the plate body 100 is directly separated from the fender assembly 300 when impacted, thereby causing failure of the force transmission structure.

[0047] In one embodiment, the second reinforcing portion 602 includes at least two second sub-reinforcing plates (not shown in the figure), which are stacked and have the same or gradually decreasing sizes in a direction away from the board body 100 .

[0048] Specifically, the stacking method of the plurality of second sub-reinforcement plates is not limited in the embodiment of the present application. The plurality of second sub-reinforcement plates can be stacked in a manner of maintaining center alignment or eccentric stacking. At the same time, the specific shape of the second sub-reinforcement plates is not limited in the embodiment of the present application. The second sub-reinforcement plates can be square plate-shaped members. In some embodiments not shown, the second sub-reinforcement plates can also be circular plate-shaped members or curved panels with curved surfaces.

[0049] It should be noted that the embodiment of the present application does not limit the connection method between multiple second sub-reinforcement plates, or the connection method between the second sub-reinforcement plates and the plate body 100. The second sub-reinforcement plates and the second sub-reinforcement plates and the plate body 100 can be connected by fasteners such as bolts and screws, can be connected by welding, or can be connected by one-piece molding.

[0050] In this embodiment, multiple second sub-reinforcement plates are stacked and arranged such that the sizes of the second sub-reinforcement plates are the same or reduced in the direction away from the plate body 100, which can further improve the local strength of the plate body 100 in a targeted manner. At the same time, it also avoids the situation where the overall weight of the vehicle is greatly affected by increasing the thickness of the second reinforcement part 602.

[0051] In one embodiment, the first mounting surface 101 is connected to the steering support assembly of the vehicle body, and a third reinforcement portion 603 is disposed on the second mounting surface 102 , and the third reinforcement portion 603 is disposed opposite to the connection portion of the steering support assembly.

[0052] Specifically, the embodiment of the present application does not limit the specific form of the first reinforcement part 601, and it only needs to be able to strengthen the structure of the inner plate of the vehicle body pillar. Exemplarily, the third reinforcement part 603 can be a plate-shaped part. In some embodiments not shown, the third reinforcement part 603 can also be a strip-shaped part or a part of other shapes.

[0053] It should be noted that the third reinforcement portion 603 and the end portion of the steering support assembly are arranged relative to each other, and may be completely opposite to each other or partially opposite to each other, wherein "partially opposite to each other" means that the area where the third reinforcement portion 603 is connected to the plate body 100 partially overlaps with the area where the steering support assembly is connected to the plate body 100.

[0054] In this embodiment, the plate body 100 is connected to the steering support assembly to establish a force transmission route between the plate body 100 and the steering support assembly structure, thereby further improving the structural strength of the vehicle at the inner plate of the vehicle body pillar. At the same time, the third reinforcement portion 603 is arranged on the side opposite to the plate body 100 and the steering support assembly. While the structure of the plate body 100 is targetedly enhanced, the plate body 100 is prevented from affecting the connection stability between the plate body 100 and the steering support assembly. While the force is transmitted from the plate body 100 to the steering support assembly, the deformation of the plate body 100 is prevented from exceeding the standard.

[0055] In one embodiment, the third reinforcing portion 603 includes at least two third sub-reinforcing plates (not shown in the figure), which are stacked and have the same or gradually decreasing sizes in a direction away from the plate body 100 .

[0056] Specifically, the stacking method of the plurality of third sub-reinforcement plates is not limited in the embodiment of the present application. The plurality of third sub-reinforcement plates can be stacked in a manner of maintaining center alignment or eccentric stacking. At the same time, the specific shape of the third sub-reinforcement plate is not limited in the embodiment of the present application. The third sub-reinforcement plate can be a square plate-like member. In some embodiments not shown, the third sub-reinforcement plate can also be a circular plate-like member or a curved plate with a curved surface.

[0057] It should be noted that the embodiment of the present application does not limit the connection method between multiple third sub-reinforcement plates, or the connection method between the third sub-reinforcement plates and the plate body 100. The third sub-reinforcement plates and the plate body 100 can be connected by fasteners such as bolts and screws, or by welding, or by one-piece molding.

[0058] In this embodiment, multiple third sub-reinforcement plates are stacked and arranged such that the sizes of the third sub-reinforcement plates are the same or reduced in the direction away from the plate body 100, which can further improve the local strength of the plate body 100 in a targeted manner. At the same time, it also avoids the situation where the overall weight of the vehicle is greatly affected by increasing the thickness of the second reinforcement part 602.

[0059] In one embodiment, the thickness of the first reinforcing portion 601 , the second reinforcing portion 602 , and the third reinforcing portion 603 are respectively greater than or equal to 0.5 times the thickness of the plate body 100 at their respective locations, and less than or equal to 3 times the thickness of the plate body 100 at their respective locations.

[0060] It should be noted that, according to actual needs, the thickness of the plate body 100 at various locations may be the same or different, and the thickness, shape and structure of the first reinforcing portion 601 , the second reinforcing portion 602 and the third reinforcing portion 603 may be the same or different.

[0061] In this embodiment, the structural strength of the corresponding positions of the plate body 100 is ensured by limiting the thickness of the first reinforcement part 601, the second reinforcement part 602 and the third reinforcement part 603, and the overall weight of the plate body 100 is limited, so that the inner plate structure of the vehicle body pillar has good strength while also meeting the requirements of lightweight vehicle.

[0062] In one embodiment, the first reinforcement portion 601 , the second reinforcement portion 602 and the third reinforcement portion 603 are respectively formed integrally with the plate body 100 .

[0063] It should be noted that the first reinforcement part 601 , the second reinforcement part 602 and the third reinforcement part 603 may all be completely attached to the plate body 100 , or may be partially separated from the plate body 100 to meet the requirements of the vehicle structure.

[0064] Specifically, the first reinforcement portion 601 , the second reinforcement portion 602 and the third reinforcement portion 603 are all integrally formed by mold pressing.

[0065] In this embodiment, the first reinforcement part 601, the second reinforcement part 602 and the third reinforcement part 603 are integrally formed with the plate body 100, so that the integrity of the structure is improved, and the situation in which the first reinforcement part 601, the second reinforcement part 602 and the third reinforcement part 603 are separated from the plate body 100 and lose the reinforcement structure effect due to impact or the like is avoided.

[0066] It should be noted that in some of the above embodiments, the second mounting surface 102 has a plane portion, and at least one of the first reinforcement portion 601 , the second reinforcement portion 602 and the third reinforcement portion 603 is disposed on the plane portion to ensure the overall structural strength of the vehicle body pillar inner panel.
