In the following embodiments, the descriptions of the embodiments are focused on, and for the part that is not described in detail in a certain embodiment, reference may be made to the related descriptions of other embodiments.

Referring to fig. 1-5, a schematic view of a vehicle chassis is shown in fig. 1, including a battery 20, a floor panel 30, a rocker 100, and a reinforcement beam 40. A floor panel 30 is provided above the battery 20, the battery 20 being used to provide electrical power storage for the vehicle. The rocker 100 is provided on both left and right sides of the battery 20 (the front-rear direction of the battery 20 is the vehicle running direction, and the rocker 100 on the right side is omitted in the drawing). The reinforcement beam 40 is disposed above the floor panel 30 for connecting at least the side sills 100 on the left and right sides to strengthen the side impact strength of the vehicle, and the reinforcement beam 40 has a generally inverted "U" shape or "several" shape.

Specifically, the rocker 100 includes a rocker outer panel 110 and a rocker inner panel 120 that are fixedly connected. The rocker inner plate 120 is disposed on a side close to the battery 20, the rocker outer plate 110 is disposed on a side far away from the battery 20, and the rocker outer plate 110 and the rocker inner plate 120 are connected in a surrounding manner to form a rocker cavity. The rocker inner panel 120 is overlapped on the battery 20, i.e., the battery 20 is installed at the lower side of the rocker inner panel 120 and fixedly connected with the reinforcement beam 40. The rocker inner panel 120 and the rocker outer panel 110 are preferably connected by welding.

The rocker 100 further includes a connection plate disposed at a junction of the rocker inner panel 120 and the rocker outer panel 110 in the rocker cavity and fixedly connected with the rocker inner panel 120 and the rocker outer panel 110 for further reinforcing a connection strength of the rocker inner panel 120 and the rocker outer panel 110.

Thus, by providing the connecting plates for the rocker inner panel 120 and the rocker outer panel 110, the problem of the weld failure between the rocker inner panel 120 and the rocker outer panel 110 during a side collision of the vehicle can be well solved, and the side collision strength can be improved.

The battery 20 is mounted on the lower side of the rocker inner panel 120, and there is no limitation as to whether or not the rocker inner panel 120 and the battery 20 are directly connected, as long as the fixed connection is possible. In a specific embodiment, the overlapping of the inner sill plate 120 on the battery 20 is realized by adding a battery 20 bracket on the battery 20, that is, one side of the battery 20 bracket is fixedly connected with the battery 20, and the other side is fixedly connected with the sill 100, so that the manufacturing and collision requirements can be better met; of course, in some embodiments, the rocker inner panel 120 may be directly overlapped on the battery 20, which is not limited by the present utility model.

Referring to fig. 3, which shows a perspective view of a chassis of a vehicle (the rocker outer panel 110 is not shown), the connection plates include a first connection plate 210, a second connection plate 220, and a third connection plate 230. The first connection plate 210 and the second connection plate 220 are disposed in front of the third connection plate 230. The first connecting plate 210 is provided at the junction of the rocker inner panel 120 and the rocker outer panel 110 in the vertical direction (Z direction), and the first connecting plate 210 is provided at the forefront. The second connecting plate 220 and the third connecting plate 230 are provided at the junction of the rocker inner panel 120 and the rocker 100 in the horizontal direction (X direction), and the second connecting plate 220 is provided in front of the third connecting plate 230.

Referring to fig. 3 to 4, the first connecting plate 210 is disposed at a connection portion between the rocker inner plate 120 and the rocker outer plate 110 in a vertical direction, the first connecting plate 210 is fixedly connected with the rocker inner plate 120, preferably welded, and the first connecting plate 210 is detachably and fixedly connected with the rocker outer plate 110, preferably bolted, so that the rocker inner plate 120 and the rocker outer plate 110 can be well connected in a reinforcing manner, and meanwhile, the manufacture is convenient, and the manufacture efficiency is improved.

The first connecting plate 210 is provided with a bolt hole, and the threshold outer plate 110 is provided with a through hole at a position corresponding to the first connecting plate 210 for facilitating the screw rod to pass through, so that when the threshold outer plate 110 and the threshold inner plate 120 need to be fastened, an operator passes the screw rod through the threshold outer plate 110 and is connected with the first connecting plate 210 on the threshold inner plate 120 through bolts, and reinforcement fastening of the threshold inner plate 120 and the threshold outer plate 110 is realized.

It is understood that the releasable fastening connection of the rocker outer panel 110 is of particular significance for the fixed connection of the first connecting panel 210 to the rocker inner panel 120. Specifically, in general vehicle manufacturing, the rocker outer panel 110 is an upper body part, and the rocker inner panel 120 is a lower body part, i.e., the rocker inner panel 120 is fixedly connected to a structure such as a body frame, the rocker outer panel 110 is fixedly connected to parts of the upper body, and then the rocker inner panel 120 is fixed to the rocker outer panel 110 when the upper and lower bodies are assembled together.

By the scheme of the utility model, the prior manufacturing sequence of the inner rocker panel 120 and the outer rocker panel 110 can be well attached, and the inner rocker panel 120 and the outer rocker panel 110 can be fastened.

Similarly, referring to fig. 5, the second connecting plate 220 is disposed at the front end of the horizontal connection portion between the rocker inner plate 120 and the rocker outer plate 110, that is, disposed at the lower side of the front end of the rocker 100, where the second connecting plate 220 is fixedly connected to the rocker outer plate 110 first, and then the second connecting plate 220 is detachably fastened to the rocker inner plate 120, preferably bolted, so that the rocker inner plate 120 and the rocker outer plate 110 can be better connected in a reinforcing manner, and meanwhile, the manufacturing is convenient, and the manufacturing efficiency is improved. The connection manner of the third connection plate 230 to connect the rocker inner panel 120 and the rocker outer panel 110 is the same as that of the second connection plate 220, except that the third connection plate 230 is used to connect the rear ends of the rocker inner panel 120 and the rocker outer panel 110 in the horizontal direction, and detailed description thereof is omitted.

Likewise, the second connection plate 220 and/or the third connection plate 230 are first electrically welded to the rocker outer panel 110 to be pre-fixed to the rocker outer panel 120, and then are connected to the rocker inner panel 120 and the rocker outer panel 110 by bolts. The reason for the bolt connection is that the included angle between the sill inner plate 120 and the sill outer plate 110 at the joint in the horizontal direction is large, which results in a large width of the second connecting plate 220/the third connecting plate 230, and if other fixing methods, such as welding, are adopted, the fixing of the connecting plate and the sill inner plate 120 and the sill outer plate 110 cannot be well realized, so that the problem of off-welding is easy to occur, the requirement on welding operators is high, and the manufacturing efficiency is not beneficial to improvement.

Therefore, by providing the first connecting plate 210, the second connecting plate 220 and the third connecting plate 230, the reinforcement and fixation of the connection positions of the rocker inner plate 120 and the rocker outer plate 110 at each part can be well realized, the connection strength of the rocker inner plate 120 and the rocker outer plate 110 can be effectively improved, and the side collision strength of the vehicle can be further improved. With continued reference to fig. 1-2, the rocker 100 further includes extruded aluminum disposed within the rocker cavity. One side of the extruded aluminum is connected to the rocker outer panel 110, and the other side is connected to the rocker inner panel 120. The extruded aluminum overlaps the reinforcement beam 40 in a vertical direction, preferably in the same horizontal plane. The bottom end of the extruded aluminum is located at a higher level than the top end of the battery 20, so that the extruded aluminum is located at a higher position than the battery 20. The advantage of this arrangement is that by arranging the position of the extruded aluminum to overlap with the position of the reinforcing beam 40 and locating the extruded aluminum above the battery 20, the battery 20 can be protected as much as possible while ensuring the collision strength.

According to the scheme of the utility model, when the vehicle is in side collision, the extruded aluminum can bear main side collision force at first, and the rest side collision force is absorbed by a threshold cavity enclosed by the threshold inner plate 120 and the threshold outer plate 110 in a mode of deformation of the threshold outer plate 110 and/or the threshold inner plate 120. When the extruded aluminum is displaced toward the inside of the vehicle, the displacement of the extruded aluminum toward the inside of the vehicle is minimized due to the reinforcing beam 40, so that the extruded aluminum is preferentially deformed and then displaced toward the inside of the vehicle, thereby maximally avoiding damage to the battery 20.

With continued reference to fig. 2-3, at least a portion of the inner rocker panel 120 at a location corresponding to the battery 20 is provided with a protrusion toward the battery 20 for further increasing the horizontal distance from the outer rocker panel 110 to the battery 20, increasing the area of the rocker cavity defined by the inner rocker panel 120 and the outer rocker panel 110, increasing the crushing moment of the cross section, increasing the absorption of collision energy during a collision, and minimizing damage to the battery 20. Therefore, by providing the protruding structure facing the battery 20 on the rocker inner panel 120, when the rocker structure collapses into the vehicle, the battery 20 is not damaged even if a certain displacement occurs due to the protruding structure, and the protection capability of the battery is improved.

In a preferred embodiment, the battery 20 is provided with a bridging frame 21, and the bridging frame 21 is provided in a direction of the battery 20 toward the outside of the vehicle for bridging with the rocker inner panel 120. The vertical surface where the outer wall of the reinforcement beam 40 is located is outside the vertical surface where the outer wall of the battery 20 is located, that is, the outer wall of the reinforcement beam 40 is outside the outer wall of the battery 20, so that the protruding structure of the rocker inner plate 120 is the position of the rocker inner plate 120 between the reinforcement beam 40 and the lap joint frame 21, and protrudes toward the battery direction.

Further, the rocker inner panel 120 extends to the outside as much as possible in the lower region of the position corresponding to the bridge 21, thereby increasing the area of the open cavity formed below the bridge 21 as much as possible, and realizing as little damage as possible to the battery 20 when a side collision occurs.

Of course, the utility model also relates to a vehicle comprising said vehicle rocker 100.
