The utility model discloses an oil pan and walking engineering machinery belong to engine technical field, the upper surface of oil pan is equipped with structure outer ring, is equipped with bolt hole on structure outer ring, and the front of left and right sides of oil pan is equipped with bolt bolster, and the rear of oil pan is equipped with bolt bolster, oil pan is metal material and is integrally equipped with longitudinal main reinforcing rib along the extension of oil pan front and back direction and transverse main reinforcing rib along the extension of oil pan left and right direction in the inside corresponding engine cylinder body main bearing cover place, the upper end of longitudinal main reinforcing rib and transverse main reinforcing rib is flush with the upper surface of oil pan, and the lower part of longitudinal main reinforcing rib and transverse main reinforcing rib all is equipped with oil flow passageway, thereby forms the whole and is the upper surface opening and presents honeycomb type structure, and the cavity structure of other each surface closure. The utility model can solve the problem that the engine cylinder body lower end surface design is thick and heavy, and the appearance design of oil pan is complex but the strength is insufficient.

The application discloses a vehicle body front compartment structure and a vehicle, and relates to the technical field of automobile manufacturing. On one hand, the vehicle body front compartment structure comprises a front wall assembly, sliding box body assemblies, a main anti-collision beam assembly, a connecting assembly and a secondary anti-collision beam assembly. The two sliding box body assemblies are connected with the upper longitudinal beam assembly along the vehicle width direction respectively, and the sliding box body assembly is provided with a mounting guide groove along the vehicle height direction. The main anti-collision beam assembly is connected with the lower longitudinal beam assembly. The connecting assembly is slidably connected with the mounting guide groove of the sliding box body assembly, and is used for being connected with the main anti-collision beam assembly or mounting the secondary anti-collision beam assembly. On the other hand, the application further provides a vehicle comprising the vehicle body front compartment structure. Through the arrangement of the sliding box body assembly, the main anti-collision beam assembly, the secondary anti-collision beam assembly, the connecting assembly, the upper longitudinal beam assembly and the lower longitudinal beam assembly are connected as a whole, the mechanical properties of the vehicle body are improved, and through the adjustment of the positions and the mounting quantity of the connecting assembly and the secondary anti-collision beam assembly, the platformization and the modularization of vehicle development are realized.

The utility model embodiment proposes a kind of front wall upper component, front wall assembly and vehicle, comprising: front wall upper upper plate is located above front wall upper lower plate, the front end of front wall upper upper plate is connected with the front end of front wall upper lower plate, the rear end of front wall upper upper plate is equipped with at least one connecting flanging, connecting flanging extends downward relative to front wall upper upper plate, the rear end of front wall upper upper plate is spaced apart from front wall upper lower plate to define buffer space, and the rear end of front wall upper upper plate is connected with front wall upper lower plate by connecting flanging.The front wall upper component of the utility model embodiment can weaken the structural strength of the pedestrian head impact site, improve pedestrian protection safety, and can improve the stability between the front wall upper upper plate and the front wall upper lower plate, optimize the front wall upper component mode, reduce the vibration noise in the vehicle, ensure user use experience, and the structure is simple, can reduce production cost, improve lightweight, to improve the vehicle endurance performance, and the use effect is better.

This invention relates to the field of battery technology and discloses a battery cell and a battery pack. The battery cell includes: a housing, the housing including a first stepped portion and a second stepped portion, the second stepped portion extending from one side of the first stepped portion in a first direction away from the first stepped portion; an electrode post disposed on the side of the first stepped portion away from the second stepped portion in the first direction; a first explosion-proof valve disposed on both sides of the second stepped portion in a second direction; the housing includes a first connecting surface and a second connecting surface, the first connecting surface being disposed on both sides of the first stepped portion in the second direction, and the second connecting surface being disposed on the side of the first stepped portion along the first direction adjacent to the second stepped portion, the first connecting surface and the second connecting surface being adhesive surfaces and / or heat dissipation surfaces. The battery cell and battery pack provided by this invention improve thermal management performance while achieving thermoelectric separation.

The invention relates to a vehicle which comprises a vehicle frame, a power assembly and a suspension device, the suspension device comprises a bracket and a suspension assembly, and the bracket comprises a supporting plate; the two connecting plates are connected to the two ends of the supporting plate respectively, extend upwards and are connected with a frame respectively; the lower end of the suspension assembly is installed on the upper side of the supporting plate. The power assembly comprises a first installation point and two second installation points, the two second installation points are located on the left side and the right side of the power assembly, the first installation point is located on the bottom wall of the power assembly, the front portion of the power assembly is fixed to the vehicle frame through the two second installation points, and the rear portion of the power assembly is fixed to the upper end of the suspension assembly through the first installation point. The suspension assembly is connected to the first mounting point, so that the elastic center of the suspension assembly is closer to the torque shaft, and the decoupling effect is improved. The bracket can solve the problem that no frame used for being connected with the suspension assembly exists below the bottom wall of the power assembly, the suspension assembly is installed on the bracket, and the problem can be solved by connecting the bracket to the frame.
