For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] Unless otherwise specified, the front-to-back direction in the present application is the longitudinal direction of the vehicle, that is, the X direction; the left-right direction is the lateral direction of the vehicle, that is, the Y direction; and the up-down direction is the vertical direction of the vehicle, that is, the Z direction.

[0041] Reference below Figure 1-Figure 11 A threshold inner panel assembly 100 according to an embodiment of the utility model is described. The threshold inner panel assembly 100 can reduce the manufacturing cost of the threshold inner panel assembly 100, enhance the rigidity and strength of the threshold inner panel assembly 100, improve the deformation resistance of the side impact, and effectively absorb the energy transmitted from the front of the vehicle when responding to a 25% small offset impact, thereby protecting the safety of passengers.

[0042] like Figure 1-Figure 11 As shown, the rocker inner panel assembly 100 according to the embodiment of the utility model comprises: a rocker inner panel 1 , a rocker front reinforcement plate 2 , a rocker front reinforcement beam 3 and a side impact load-sharing beam 4 .

[0043] It should be noted that the sill inner panel assembly 100 is installed on the vehicle, and can be specifically assembled with the sill outer panel assembly to form a sill beam assembly, and the sill beam assembly is installed at the outer edge of the vehicle body floor. The sill inner panel assembly 100 is located on the inner side of the sill outer panel assembly, and is relatively distributed with the sill outer panel assembly along the inner and outer directions of the vehicle transverse direction, that is, the two sides of the sill inner panel 1 along the thickness direction are divided into inner and outer sides, and the sill inner panel assembly 100 and the sill outer panel assembly are both arranged to extend vertically along the vehicle.

[0044] The sill front reinforcement plate 2 and the sill front reinforcement beam 3 are both installed on the outer side of the sill inner panel 1, wherein the sill front reinforcement plate 2 is installed on the outer front part of the sill inner panel 1, and the sill front reinforcement beam 3 is installed on the side of the sill front reinforcement plate 2 away from the sill inner panel 1. The sill inner panel 1, the sill front reinforcement plate 2 and the sill front reinforcement beam 3 are distributed in sequence along the inner and outer directions to form a three-layer reinforcement structure, which can realize the collision force transmission of three paths in the longitudinal direction and realize layered protection in the transverse direction, thereby strengthening the strength and rigidity of the sill inner panel 1, improving the deformation resistance of the sill inner panel assembly 100, absorbing the collision energy when a side collision occurs, and improving the side collision deformation resistance performance.

[0045] Specifically, Figure 1 As shown, the threshold front reinforcement plate 2 and the threshold front reinforcement beam 3 are located in the front part of the threshold inner plate 1, and the inner side of the threshold front reinforcement plate 2 is installed in contact with the outer side of the threshold inner plate 1, and the threshold front reinforcement beam 3 is installed in contact with the threshold front reinforcement plate 2, that is, it is installed on the side of the threshold reinforcement plate away from the threshold inner plate 1. The threshold front reinforcement plate 2 and the threshold inner plate 1 can be connected by welding, and the threshold front reinforcement beam 3 and the threshold front reinforcement plate 2 can also be connected by welding, thereby increasing the connection strength between the threshold front reinforcement plate 2, the threshold front reinforcement beam 3 and the threshold inner plate 1, and improving their connection reliability. In addition, by adding the threshold front reinforcement plate 2 and the threshold front reinforcement beam 3, the vehicle can also effectively absorb the energy transmitted from the front of the vehicle when responding to a 25% small offset collision, and the threshold front reinforcement plate 2 and the threshold front reinforcement beam 3 will not fall off, thereby ensuring the safety of the passengers, thereby simultaneously meeting the side collision index requirements and the 25% small offset requirements, improving the performance of the whole vehicle and reducing costs.

[0046] The side impact sub-beam 4 can further improve the strength and rigidity of the threshold inner panel 1, absorb energy when the vehicle collides with the side, and improve the side impact anti-deformation performance, thereby ensuring the safety of passengers. The side impact sub-beam 4 is installed on the outer side of the threshold inner panel 1, and the side impact sub-beam 4 is located at the rear side of the threshold front reinforcement plate 2, so that the threshold front reinforcement plate 2 and the side impact sub-beam 4 jointly perform anti-deformation in the front-to-back direction, thereby greatly reducing the length direction of the side impact sub-beam 4, that is, reducing the size of the side impact sub-beam 4 installed on the threshold inner panel 1 along the front-to-back direction, thereby reducing the weight of the side impact sub-beam 4, and only one-third of the weight of the traditional side impact sub-beam 4, thereby greatly reducing the manufacturing cost of the threshold inner panel assembly 100, and at the same time, the overall weight of the threshold inner panel assembly 100 is not increased, ensuring the overall weight of the threshold inner panel assembly 100.

[0047] In actual design, the side impact load-bearing beam 4 can be made of T6 aluminum profile, which can further reduce the weight of the side impact load-bearing beam 4 while ensuring the side impact performance, and the threshold front reinforcement plate 2 and the threshold front reinforcement beam 3 can also use aluminum profiles, or steel plates, etc., which can be flexibly selected according to actual needs.

[0048] According to the threshold inner panel assembly 100 of the embodiment of the utility model, by providing a threshold front reinforcement plate 2 and a threshold front reinforcement beam 3, the side impact load-bearing beam 4 is located at the rear side of the threshold front reinforcement plate 2, so that the size and weight of the side impact load-bearing beam 4 can be reduced, thereby reducing the cost, and the strength and rigidity of the threshold inner panel assembly 100 can be improved, thereby improving the deformation resistance of the threshold inner panel assembly 100, and can simultaneously meet the side impact index requirements and the 25% small offset requirements, thereby improving the performance of the entire vehicle and protecting the safety of passengers.

[0049] In some embodiments, a load-bearing sub-beam reinforcement plate 5 is further provided on the outer side of the sill inner panel 1, and the front portion of the side impact load-bearing sub-beam 4 is connected to the rear portion of the sill front reinforcement plate 2, and the rear portion of the side impact load-bearing sub-beam 4 is connected to the load-bearing sub-beam reinforcement plate 5. Thus, the collision force from the sill front reinforcement plate 2 to the side impact load-bearing sub-beam 4 can be transferred. In addition, the load-bearing sub-beam reinforcement plate 5 is installed between the side impact load-bearing sub-beam 4 and the sill inner panel 1 to provide support and structural reinforcement, thereby greatly improving the structural strength of the sill inner panel assembly 100 and improving its anti-deformation capability, thereby further improving the side impact performance of the sill inner panel assembly 100.

[0050] in, Figure 1The left-right direction is the front-to-back direction of the threshold inner panel 1, the threshold front reinforcement plate 2 is installed at the left side position of the threshold inner panel 1, that is, the outer front part, and then the side impact sub-beam 4 is installed along the length direction of the threshold inner panel 1 on the right side, that is, the rear side of the threshold reinforcement plate, and the sub-beam reinforcement plate 5 is separated from the threshold front reinforcement plate 2 by a certain distance and arranged behind the threshold reinforcement plate. In this way, the front part of the side impact sub-beam 4 can be connected to the rear part of the threshold front reinforcement plate 2, and the rear part of the side impact sub-beam 4 is connected to the sub-beam reinforcement plate 5. As a result, the front and rear ends of the side impact sub-beam 4 are supported and fixed by the threshold front reinforcement plate 2 and the sub-beam reinforcement plate 5, which improves the strength of the side impact sub-beam 4 and ensures the installation stability of the side impact sub-beam 4.

[0051] In some embodiments, the side impact sub-beam 4 and the door sill front reinforcement plate 2 and / or the side impact sub-beam 4 and the sub-beam reinforcement plate 5 are detachably connected via a connecting piece.

[0052] The side impact sub-beam 4 and the front reinforcement plate 2 of the door sill and the side impact sub-beam 4 and the sub-beam reinforcement plate 5 are arranged to be detachably connected, which can facilitate the installation of the side impact sub-beam 4. When the side impact sub-beam 4 is damaged during use, it is convenient to remove the side impact sub-beam 4 separately for replacement and maintenance. This is flexible and convenient. With this arrangement, there is no need to remove the entire connected side impact sub-beam 4 and the front reinforcement plate 2 of the door sill, thereby reducing the number of operating steps. In actual design, the connecting parts can be selected as bolts, screws, etc.

[0053] Specifically, Figure 1 and Figure 6 As shown, the front and rear parts of the side impact sub-load beam 4 are respectively provided with two through holes, that is, a total of four through holes are provided on the side impact sub-load beam 4, two matching holes are correspondingly provided on the rear part of the threshold front reinforcement plate 2, and two matching holes are also correspondingly provided on the sub-load beam reinforcement plate 5, and the connecting parts can be the bearing surface projection welding bolts 6 and the hexagonal flange nuts 7, thereby, the side impact sub-load beam 4 and the threshold front reinforcement plate 2, the side impact sub-load beam 4 and the sub-load beam reinforcement plate 5 can be connected together by inserting the bearing surface projection welding bolts 6 into the through holes and the matching holes, and then the hexagonal flange nuts 7 are installed on the bearing surface projection welding bolts 6 to fix them, so as to realize the reliable connection between the various parts. Among them, the hexagonal flange nut has a good sealing performance, which can effectively prevent foreign matter from penetrating into the nut body and prevent the nut body from rusting, thereby greatly extending the service life of the hexagonal flange nut, and then extending the service life of the side impact sub-load beam 4.

[0054] In addition, the side impact load-bearing beam 4 is connected and fixed by using the bearing surface projection welding bolts 6 and the hexagonal flange nuts 7, which can further strengthen the local stiffness of the sill inner panel assembly 100, ensure the strength of the sill inner panel assembly 100 during side impact, and further ensure the side impact performance of the entire vehicle and improve the comfort of passengers.

[0055] It should be noted that the connection method between the side impact load-bearing beam 4 and the front reinforcement plate 2 of the door sill and / or the side impact load-bearing beam 4 and the load-bearing beam reinforcement plate 5 is not limited to that described in the present embodiment, and can also be directly connected by welding or other connection methods, which can be flexibly adjusted according to actual needs.

[0056] In some embodiments, a main installation groove 11 open outward is formed on the outer side of the threshold inner plate 1, and the threshold front reinforcement plate 2 and the side impact load-bearing beam 4 are distributed in the main installation groove 11 along the front-to-back direction.

[0057] Specifically, Figure 2 As shown, along the up and down directions in the figure, the upper and lower edges of the outer side of the sill inner panel 1 are formed with flanges extending outward, thereby, the upper flange, the lower flange and the main part of the sill inner panel 1 jointly define a main installation groove 11 open to the outside, the sill front reinforcement plate 2 is installed in the front part of the main installation groove 11, the side impact sub-load beam 4 is connected to the rear part of the sill front reinforcement plate 2 and installed in the main installation groove 11, and the sill front reinforcement plate 2 and the side impact sub-load beam 4 can be installed from the outside of the sill inner panel 1 into the main installation groove 11, which is convenient to install and realizes the sharing of space in the lateral direction, thereby improving the installation compactness of the sill inner panel assembly 100.

[0058] Among them, the upper part of the side impact sub-beam 4 is fitted and connected with the upper side surface of the rocker inner panel 1, and the upper and lower parts of the rocker front reinforcement plate 2 are respectively fitted and connected with the upper side surface and the lower side surface of the rocker inner panel 1, thereby ensuring the connection reliability between the rocker front reinforcement plate 2 and the side impact sub-beam 4 and the rocker inner panel 1.

[0059] In some embodiments, the threshold front reinforcement plate 2 is formed with a first installation groove 21 , the first installation groove 21 is open in a direction away from the threshold inner plate 1 , and the threshold front reinforcement beam 3 is installed in the first installation groove 21 .

[0060] Specifically, Figure 1 and Figure 2 As shown, the threshold front reinforcement plate 2 is provided with a first installation groove 21 for installing the threshold front reinforcement beam 3, and is conducive to stably installing the threshold front reinforcement plate 2 on the main installation groove 11 on the outer side of the threshold inner plate 1. The first installation groove 21 is open in the direction away from the threshold inner plate 1, that is, it is open to the outside. The size of the first installation groove 21 is adapted to the size of the main installation groove 11. Therefore, when the threshold front reinforcement beam 3 is actually installed on the main installation groove 11, the upper side surface of the first installation groove 21 can be fitted and connected with the upper side surface of the threshold inner plate 1, and the lower side surface of the first installation groove 21 can be fitted and connected with the lower side surface of the threshold inner plate 1, thereby ensuring the stability and reliability of the connection. When the threshold inner plate assembly 100 is hit sideways, the threshold front reinforcement plate 2 will not fall off.

[0061] In some embodiments, the front threshold reinforcement beam 3 is formed with a second installation groove 31, the second installation groove 31 is open toward the front threshold reinforcement plate 2, and the second installation groove 31 and the first installation groove 21 jointly define a first reinforcement cavity, so that the first reinforcement cavity can be used to avoid lateral structural deformation of the front threshold reinforcement plate 2 and the front threshold reinforcement beam 3 to achieve collision buffering.

[0062] Specifically, Figure 2 As shown, the upper end and the lower end of the threshold front reinforcement beam 3 both extend inward by a certain length to form a second installation groove 31, and the second installation groove 31 is open toward the threshold front reinforcement plate 2, that is, the first installation groove 21 and the second installation groove 31 are open to each other, thereby, when the threshold front reinforcement beam 3 is installed on the threshold front reinforcement plate 2, the first installation groove 21 is connected with the second installation groove 31, and together define a first reinforcement cavity, which can absorb more energy, improve the side impact performance, and reduce the weight of the threshold front reinforcement beam 3 and the threshold front reinforcement plate 2, and weight reduction holes can be set on the upper and lower side walls of the second installation groove 31 to further reduce the weight, thereby reducing the overall weight of the threshold inner plate assembly 100 and reducing the cost.

[0063] In some embodiments, the side impact sub-beam 4 is constructed as a hollow beam. Constructing the side impact sub-beam 4 as a hollow beam can reduce the weight and cost of the side impact sub-beam 4, and a second reinforcement cavity 41 is formed in the side impact sub-beam 4. The second reinforcement cavity 41 can absorb more energy and improve the side impact performance.

[0064] Specifically, Figure 2 and Figure 7 As shown, the side impact load-bearing beam 4 is constructed as a hollow beam structure, a second reinforcement cavity 41 is formed in the side impact load-bearing beam 4, and the size of the side of the second reinforcement cavity 41 installed close to the outer side of the sill inner panel 1 is larger than the size of the side installed away from the outer side of the sill inner panel 1.

[0065] In some embodiments, a reinforcing rib 42 is provided in the side impact sub-load beam 4, and the reinforcing rib 42 divides the second reinforcing cavity 41 into a plurality of sub-reinforcing cavities. The reinforcing rib 42 is provided to support the second reinforcing cavity 41, so as to improve the strength of the side impact sub-load beam 4. The plurality of sub-reinforcing cavities can enable the side impact sub-load beam 4 to fully absorb energy during a side impact, thereby effectively protecting the battery module.

[0066] Specifically, Figure 7 As shown, the cross-section of the side impact load-bearing beam 4 is a trapezoidal structure on the side close to the sill inner panel 1, and a rectangular structure on the side away from the sill inner panel 1. The rectangular structure and the trapezoidal structure are connected to form a second reinforcement cavity 41. A cross-shaped reinforcement rib 42 is arranged inside the second reinforcement cavity 41 to divide the second reinforcement cavity 41 into four sub-reinforcement cavities.

[0067] In actual design, the thickness of the side wall and the thickness of the reinforcing rib 42 in the rectangular structure can be set to be the same as or different from the thickness of the side wall and the thickness of the reinforcing rib 42 in the trapezoidal structure. Figure 7 As shown, the rectangular structure and the trapezoidal structure include side walls installed in the transverse direction and the vertical direction of the vehicle, wherein the thickness of the side wall in the transverse direction of the rectangular structure and the thickness of the reinforcing ribs 42 extending in the same direction inside can be set to 4 mm, and the thickness of the side wall in the transverse direction of the trapezoidal structure and the thickness of the reinforcing ribs 42 extending in the same direction inside can be set to 4.5 mm. Figure 7 As shown, in the cross section of the side impact sub-beam 4, the width of the inner wall of the side impact sub-beam 4 is L1, and can be set to 96.44 mm, the width of the outer wall of the side impact sub-beam 4 is L2, and can be set to 36.6 mm, and the thickness of the side impact sub-beam 4 along the inner and outer directions is L3, and can be set to 81.7 mm, because a sub-beam reinforcement plate 5 is also connected between the side impact sub-beam 4 and the threshold inner plate 1.

[0068] Therefore, the distance from the side of the side impact sub-beam 4 installed close to the door sill inner panel 1 to the outer side of the door sill inner panel 1 can be set to 94.5 mm, and the wall thickness of other areas of the side impact sub-beam 4 can be set to 3 mm. Thus, the transverse wall thickness of the side impact sub-beam 4 is increased, and the cross-shaped reinforcing ribs 42 are added, so that the side impact sub-beam 4 can fully absorb energy during a side impact, thereby effectively protecting the battery module.

[0069] It should be noted that the shape and size of the side impact load-bearing beam 4 are not limited to those described in this embodiment, and can be flexibly adjusted according to actual requirements.

[0070] The utility model also provides a threshold beam assembly.

[0071] According to the embodiment of the utility model, the threshold beam assembly includes a threshold outer panel assembly, a threshold reinforcement plate, and a threshold inner panel assembly 100 of any of the above embodiments, the threshold inner panel assembly 100 and the threshold outer panel assembly are connected in the inner and outer directions, and the threshold reinforcement plate is located between the threshold inner panel assembly 100 and the threshold outer panel assembly, and the threshold reinforcement plate is used to be connected to the A-pillar lower reinforcement plate. In other words, the threshold inner panel assembly 100 is connected in the inner and outer directions of the vehicle transverse direction, the threshold outer panel assembly is connected to the threshold inner panel assembly 100 outwardly, and the threshold reinforcement plate is arranged between the threshold inner panel assembly 100 and the threshold outer panel assembly, which can also improve the connection strength and reliability between the threshold inner panel assembly 100 and the threshold outer panel assembly.

[0072] Among them, in the front and rear direction, the front door sill reinforcement plate 2 is located at the connection between the door sill reinforcement plate and the lower reinforcement plate of the A-pillar, that is, the A-pillar is located in front and above the door sill reinforcement plate and the front door sill reinforcement plate 2. Such an arrangement allows the front door sill reinforcement plate 2 to be supported at the connection between the door sill reinforcement plate and the lower reinforcement plate of the A-pillar when a small offset collision of 25% occurs, thereby enhancing the strength of the connection, thereby allowing the door sill reinforcement beam to effectively absorb energy.

[0073] The utility model also provides a vehicle.
