More and more vehicles adopt a vehicle body battery design, and the vehicle body battery can meet the requirement of integrated design, but if the structural design of the vehicle body battery is unreasonable, if the structural strength requirement of a battery pack is met, the battery pack upper cover assembly is designed into a combined structure of a steel plate and a fireproof heat insulation plate, and the steel plate and the fireproof heat insulation plate are all of solid structures, so that the structural reinforcing effect of the battery pack is not obvious, the weight of the battery pack is increased, and the lightweight development of the whole vehicle is not facilitated.

In order to solve the technical problem that current battery package upper cover subassembly can't compromise structural strength and weight, the application provides a battery package upper cover subassembly that provides has proposed the integrated configuration of buffer board subassembly and braced frame, improves the structural strength of battery package upper cover subassembly through braced frame, simultaneously, reduces the whole weight of battery package upper cover subassembly through the buffer board subassembly.

In this embodiment, the battery pack upper cover assembly 100 provided herein provides a combined structure of the buffer plate assembly 21 and the supporting framework 22, and the structural strength of the battery pack upper cover assembly 100 is improved through the supporting framework 22, and meanwhile, the overall weight of the battery pack upper cover assembly 100 is reduced through the combined mode of combining the supporting framework 22 with the buffer plate assembly 21.

Specifically, when an occupant in the vehicle applies a pedaling force to the pedal assembly 20, the buffer plate assembly 21 of the pedal assembly 20 can transmit the pedaling force to the support frame 22, the support frame 22 can bear the pedaling force, and the pedaling force is dispersed to the whole support frame 22 and the buffer plate assembly 21, so that the purpose of dispersing the pedaling force is achieved, and the phenomenon of stress concentration of the buffer plate assembly 21 when the pedaling force of the occupant is borne is reduced.

Through verification, under the condition that the requirement of preset structural strength is met, if the battery pack upper cover assembly 100 of the embodiment of the application is adopted, the weight is only 11.08Kg, and the battery pack upper cover assembly in the prior art is adopted, and the weight is 26.2Kg, the battery pack upper cover assembly 100 of the embodiment of the application can reduce the weight by 15.12Kg compared with the battery pack upper cover assembly in the prior art, and the weight reduction ratio reaches 57.7%.

In addition, as will be appreciated by those skilled in the art, since the support frame 22 is the main load-bearing structure of the pedal assembly 20, and the buffer plate assembly 21 is the main weight-reducing, energy-absorbing and fire-proof structure of the pedal assembly 20, the embodiment of the present application, based on this consideration, proposes to set the support frame 22 to be made of a metal material, for example, the support frame 22 may be made of steel, and the buffer plate assembly 21 is set to be made of EPP buffer foam, so as to satisfy the structural strength requirement of the support frame 22 and the energy-absorbing and weight-reducing requirement of the buffer plate assembly 21.

Further, in order to reduce the risk of the pedal assembly 20 damaging the battery pack 200 during the process of receiving the pedaling force, the embodiments of the present application also propose to provide the battery cover plate 10 to be made of a composite PCM material, thereby improving the structural stability of the battery pack upper cover assembly 100 and the battery pack 200.

It should be noted that the structures of the supporting frame 22 and the buffer plate assembly 21 are not limited in this embodiment, because the structures of the supporting frame 22 and the buffer plate assembly 21 include various types, such as a grid structure, a matrix structure, a concentric circle structure, or a non-character structure, which are all included in the protection scope of the supporting frame 22 in this application. Also, the structure of the buffer plate assembly 21 is not limited in this embodiment, because the structure of the buffer plate assembly 21 includes various types as well, such as an integral structure, a split structure, or a detachable structure, and the like, and such structures all belong to the protection scope of the buffer plate assembly 21 in this application.

As shown in fig. 3 and 4, in some embodiments, the supporting frame 22 is provided in an arch structure, and the buffer plate assembly 21 includes an upper buffer plate 211 and a lower buffer plate 212 respectively located at upper and lower sides of the supporting frame 22, and the upper buffer plate 211 and the lower buffer plate 212 are each provided with an arch surface engaged with the supporting frame 22.

Specifically, the supporting frame 22 operates on a principle similar to that of an arch bridge, and when an occupant in a vehicle applies a stepping force to the supporting frame 22, the arch structure can transfer the stepping force to both sides of the arch structure, so that the purpose of dispersing the stepping force is achieved. Further, since the support frame 22 is provided to be bent in a direction away from the battery pack 200, even if the pedaling force received by the support frame 22 exceeds the plastic deformation capability of the support frame 22, the support frame 22 can buffer the pedaling force by plastic deformation itself, reducing the phenomenon that the arch profile breaks after receiving an external force or directly transmits the pedaling force to the battery pack 200.

Further, both ends of the supporting frame 22 are respectively provided with the cross beam 30 of the vehicle seat and the side wall of the battery pack 200, and both ends of the supporting frame 22 are respectively connected with the cross beam 30 of the vehicle seat and the side wall of the battery pack 200, after the pedal assembly 20 bears the stepping force, the pedal assembly 20 can transmit the stepping force to the cross beam 30 and the side wall of the battery pack 200 through the supporting frame 22, so that the stepping force transmitted to the battery pack 200 by the pedal assembly 20 is reduced.

In this embodiment, by arranging the support frame 22, the upper buffer plate 211 and the lower buffer plate 212 with detachable components, not only the manufacturing difficulty of the buffer plate component 21 can be reduced, but also the assembly difficulty of the buffer plate component 21 and the support frame 22 can be reduced. Because, it will be appreciated by those skilled in the art that if the buffer plate assembly 21 is provided as a unitary structure, it is necessary to provide mounting slots in the buffer plate assembly 21 which not only increase the difficulty of manufacture, but also increase the difficulty of assembly of the support frame 22.

Further, the upper buffer plate 211 and the lower buffer plate 212 are provided with embedded grooves matched with the supporting framework 22, and at least part of the supporting framework 22 is embedded and matched with the embedded grooves of the upper buffer plate 211 and the lower buffer plate 212 in the process of assembling the upper buffer plate 211, the lower buffer plate 212 and the supporting framework 22, so that the purposes of limiting the upper buffer plate 211, the lower buffer plate 212 and the supporting framework 22 are achieved, and the phenomena of relative sliding and dislocation of the upper buffer plate 211, the lower buffer plate 212 and the supporting framework 22 in the assembling process are reduced.

In addition, by providing the supporting frame 22 as a combined structure of the hollowed-out plate 221 and the plurality of ribs 222, the overall weight of the supporting frame 22 can also be reduced.

Specifically, the hollowed-out plate 221 includes a grid structure, a matrix distribution structure, a concentric circle structure, and the like, and the plurality of ribs 222 are distributed at equal intervals along the length direction of the hollowed-out plate 221, so as to achieve the technical effect that the hollowed-out plate 221 uniformly distributes the treading force to the plurality of ribs 222, and reduce the phenomenon of uneven stress distribution between the hollowed-out plate 221 and the plurality of ribs 222.

Further, when the length of the rib 222 is longer, ribs can be further erected on the rib 222, and the ribs are connected with the plurality of ribs 222 along the length direction of the hollowed-out plate 221, so that the effect of transferring stress among the plurality of ribs 222 is achieved, the purpose that the plurality of ribs 222 can synchronously bear the stress is achieved, and the phenomenon that stress is unevenly dispersed among the plurality of ribs 222 or the local rib 222 is damaged is reduced.

As shown in fig. 4 and 5, in some embodiments, the hollowed-out plate 221 and the ribs 222 form an integrally formed non-character-shaped structure, and the hollowed-out plate 221 is configured as a flat plate structure, and the ribs 222 form an arch-shaped curved structure.

In this embodiment, the hollowed-out plate 221 with the flat plate structure can achieve the effect of uniformly bearing the stepping force, and the ribs 222 form an arch structure, so that the ribs 222 can buffer and transmit the stepping force by utilizing the deformation of the hollowed-out plate 221 in the process of transmitting the stepping force to the ribs 222, thereby achieving the purpose of dispersing the stepping force.

Further, the material of fretwork board 221 includes steel, almag, titanium alloy etc. fretwork board 221 can set up a plurality of oval holes, round hole, waist type hole, lightening hole such as square hole, and rib 222 can set up to lath structure or rod structure, and rib 222 sets up as integral type cutting shaping or welding shaping with fretwork board 221, and these embodiments all belong to the protection scope of this application.

As shown in fig. 5 and 6, in some embodiments, the battery pack top cover assembly 100 further includes a cross beam 30 disposed above the battery cover plate 10, the hollowed-out plate 221 and the plurality of ribs 222 are all distributed along the length direction of the cross beam 30, and the pedal assembly 20 is mounted to the cross beam 30 through the plurality of ribs 222.

In the present embodiment, by mounting the plurality of ribs 222 of the pedal assembly 20 to the cross member 30, after the pedal assembly 20 receives the pedaling force, the pedal assembly 20 can transmit the pedaling force to the cross member 30 through the plurality of ribs 222, thereby reducing the pedaling force transmitted from the pedal assembly 20 to the battery pack 200.

Specifically, the cross member 30 is connected with the vehicle body, when the passenger steps on the pedal assembly 20, the stepping force borne by the pedal assembly 20 is sequentially transferred to the upper buffer plate 211 and the supporting frame 22, then the supporting frame 22 uniformly transfers the stepping force to the plurality of ribs 222, and the plurality of ribs 222 transfer the stepping force to the cross member 30, so that the purposes of dispersing and transferring the stepping force are achieved, and the risk of damage to the pedal assembly 20 and the battery pack 200 due to the stepping force is reduced.

As shown in fig. 5 to 6, in some embodiments, the lateral side of the cross member 30 is provided with a plurality of mounting grooves in one-to-one correspondence with a plurality of ribs 222 located on the side of the cross member 30, the free end of the rib 222 located on the side of the cross member 30 is provided with a flange 223 extending to the cross member 30, and the rib 222 is connected to the mounting groove of the cross member 30 through the flange 223.

In the present embodiment, the mounting groove of the cross beam 30 not only can provide a mounting space for the rib 222, but also can achieve the purpose of clamping the rib 222, so as to improve the connection stability of the rib 222 and the cross beam 30 and reduce the phenomenon that the rib 222 is separated from the cross beam 30 after bearing the stepping force.

Specifically, the assembling mode of the rib 222 and the mounting groove comprises bonding, clamping and screwing, wherein the rib 222 positioned in the treading area can be connected with the mounting groove in a bonding and screwing dual connection mode, so that the connection stability of the rib 222 in the treading area is improved, and the rib 222 far away from the treading area can be connected with the mounting groove in a bonding mode, so that the assembling difficulty of the rib 222 and the mounting groove is reduced.

In the present embodiment, by attaching the plurality of ribs 222 of the pedal assembly 20 to the side wall of the battery pack 200, after the pedal assembly 20 receives the pedaling force, the pedal assembly 20 can transmit the pedaling force to the side wall of the battery pack 200 through the plurality of ribs 222, thereby reducing the pedaling force transmitted from the pedal assembly 20 to the battery cover 10. Specifically, when the passenger steps on the pedal assembly 20, the stepping force borne by the pedal assembly 20 is sequentially transferred to the upper buffer plate 211 and the supporting frame 22, then the supporting frame 22 uniformly transfers the stepping force to the plurality of ribs 222, and the plurality of ribs 222 transfer the stepping force to the connecting piece and the side wall of the battery pack 200, so that the purpose of dispersing and transferring the stepping force is achieved, and the risk of damage to the pedal assembly 20 and the battery cover plate 10 due to the stepping force is reduced.

Specifically, the free ends of the ribs 222, which are far from the side of the cross beam 30, are provided with mounting holes 224 (e.g., screw holes), and the side walls of the battery cover plate 10 and the battery pack 200 are also provided with mounting holes (e.g., screw holes), and during the assembly of the battery pack upper cover assembly 100, the mounting holes 224 of the ribs 222 are aligned with the mounting holes of the battery cover plate 10 and the battery pack 200, and then sequentially pass through the ribs 222, the battery cover plate 10 and the side walls of the battery pack 200 through connectors (e.g., bolts), thereby achieving the purpose of integrally assembling the ribs 222 and the battery cover plate 10 to the side walls of the battery pack 200.

As shown in fig. 1 and 3, in some embodiments, two beams 30 are disposed on top of the battery cover plate 10, and a gap is formed between the two beams 30 and located in the middle of the pedal assembly 20, and two pedal assemblies 20 are disposed on two sides of the two beams 30 opposite to the gap.

In this embodiment, the battery cover 10 is configured as an integral structure, the battery cover 10 integrally covers the top opening of the battery pack 200, so as to improve the connection tightness between the battery cover 10 and the battery pack 200, and two split pedal assemblies 20 are covered on the top of the battery cover 10, so that the coverage area and the bearing moment of each pedal assembly 20 can be reduced. Because, as will be appreciated by those skilled in the art, the larger the coverage area, the larger the bearing moment, and the higher the structural strength requirement for the pedal assembly 20, the further improvement of the structure or weight of the pedal assembly 20 is required, which is not beneficial to the light weight and compact development of the pedal assembly 20, and therefore, the embodiment of the present application proposes a scheme for partitioning the two battery pack upper cover assemblies 100, so as to reduce the overall weight of the pedal assembly 20, and is beneficial to the light weight and compact development of the pedal assembly 20.
