This application relates to the field of vehicle component manufacturing, and discloses a wheel guard assembly and a vehicle. The wheel guard assembly includes a vehicle body, a wheel guard, and a wheel arch liner. Along a first direction, the wheel guard is disposed between the vehicle body and the wheel arch liner. Along a second direction, a portion of the wheel guard protrudes from the vehicle body. The first and second directions are perpendicular to each other, with the first direction being the height direction of the vehicle body and the second direction being the width direction of the vehicle body. This application, by placing a wheel guard between the vehicle body and the wheel arch liner, and making a portion of the wheel guard protrude from the vehicle body along its width direction, can replace the function of wheel arches in related technologies. The wheel guard can be formed by increasing the size of a mudguard. Compared to solutions in related technologies, the elimination of wheel arches reduces mold and material costs, and lowers the overall weight of the vehicle.

The utility model provides a replaceable plate bundle unit full welding plate type gas-gas heat exchanger, a plurality of single plate bundle units respectively constitute high temperature plate bundle unit and low temperature plate bundle unit, and the high temperature plate bundle unit and low temperature plate bundle unit are sealedly installed on the support bottom pry in proper order, and the lower part of the support bottom pry is connected with the bottom connection header; the hot side import header, hot side export header are sealedly installed in the upper portion of high temperature plate bundle unit and low temperature plate bundle unit respectively; the cold side import header, cold side export header are sealedly installed in the end of high temperature plate bundle unit and low temperature plate bundle unit, and the outside of high temperature plate bundle unit and low temperature plate bundle unit is sealedly connected with the outer pressure plate, in the utility model, if single plate bundle unit occurs corrosion or premature failure damage, single plate bundle unit can be replaced on the spot, and the subsequent maintenance cost of equipment is reduced, and simultaneously through setting the flow guide plate, gas scale is reduced, the flow characteristics of gas medium in the heat exchanger is strengthened, heat exchange efficiency is increased, and long period stable operation of equipment is ensured.

The utility model relates to water pump rotor technical field discloses a motor rotor structure with high applicability, including rotary shaft, the surface fixedly connected with mounting seat of rotary shaft, the surface of mounting seat is opened dovetail groove, the inner wall sliding connection of dovetail groove has dovetail block, the left end both sides of dovetail block are provided with limit block, the surface fixedly connected with permanent magnet of dovetail block, the surface bushing of rotary shaft has fixed base, the inner wall of fixed base is opened cross groove, the inner wall of cross groove is inserted and is connected with mounting plate. The utility model through dismantling fastening bolt cancels the fixed of dovetail block, then will take down mounting plate, will slide out and take out permanent magnet, is convenient for replacing permanent magnet alone, has reduced the follow -up maintenance cost, has reduced the waste of resources, has improved practicality, convenient for replacing permanent magnet of different thickness according to the demand simultaneously, is applicable to different types of motor and application scene, has improved applicability.

The application discloses an assembled silicon gold plate and belongs to the technical field of building decoration materials. The silicon gold plate comprises a mounting base plate, a calcium silicate plate and an assembly clamping assembly. A bonding layer, a buffer damping layer, a heat insulation layer and a moisture-proof layer are sequentially arranged between the mounting base plate and the calcium silicate plate, forming a multifunctional composite structure. The assembly clamping assembly is composed of a matching assembly clamping strip and an assembly clamping claw. The clamping strip is arranged on the left side of the base plate, and the clamping claw is arranged on the right side. Quick assembly is realized through clamping connection. The bottom of the calcium silicate plate is provided with a mounting cross beam and an assembly track. The clamping strip and the clamping claw are adapted to the track through an extension adjustment structure and are locked by using spring pre-tightening force. The application solves the problems of complicated installation, insufficient anti-seismic and moisture-proof performance of traditional silicon gold plates, has the advantages of efficient assembly, superior heat insulation and moisture-proof performance, stable connection and the like, and is suitable for building inner and outer wall decoration and complex environment scenes.

This invention provides a valve sleeve spiral positioning and guided electro-hydraulic proportional servo valve. The electro-hydraulic proportional servo valve includes a spool valve assembly, an oil port changing plate at the left end of the spool valve assembly, and an electric actuator at the right end of the spool valve assembly. A valve core that can slide in the axial direction is disposed inside the spool valve assembly, and the valve core portion is inserted into the electric actuator. A guide-stage valve sleeve is rotatably connected inside the electric actuator, and the guide-stage valve sleeve is connected to the valve core insertion portion. A guide structure is provided between the valve core insertion portion and the guide-stage valve sleeve. This invention successfully reduces the moment of inertia, enabling the motor to drive the valve core movement with lower torque output. Furthermore, this invention can also reduce the subsequent maintenance costs of the servo valve.
