Description

Technical Field

[0001] This utility model belongs to the field of motor technology, specifically relating to a heat dissipation and heat insulation cover for a motor pump of an active suspension system in an automobile. Background Technology

[0002] The electric motor pump is a core power component in an automotive active suspension system, and it is mostly a hydraulic pump. The main type of hydraulic pump is a four-quadrant internal gear pump. Using a hydraulic four-quadrant internal gear pump, in conjunction with a permanent magnet synchronous motor and control unit, and connected to the shock absorbers via hydraulic lines, it achieves independent control of the damping and leveling adjustment of each wheel. This system is relatively large and is often installed between the two axles, providing power to the suspension on both sides via hydraulic lines.

[0003] Since electric motor pumps are installed in the suspension system, the most common practice to protect them is to install a heat shield on the outside of the pump. Because the temperature of the environment around the pump differs between the inside and outside of the heat shield, the area around the pump becomes hotter during extended operation, while the area outside the heat shield becomes slightly cooler.

[0004] This leads to a problem: although the heat shield provides insulation, it cannot provide active heat dissipation to protect the motor pump. Utility Model Content

[0005] The purpose of this invention is to provide a heat dissipation and heat insulation cover for an electric motor pump in an active suspension system of an automobile, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat dissipation and heat insulation cover for a motor pump of an active suspension system for automobiles, comprising an integrally formed top plate, a first side plate, and a second side plate. The top plate has an outwardly protruding box portion integrally formed with the top plate. The top plate is provided with an outwardly drafted heat dissipation box portion. A filter plate is detachably connected to the top of the heat dissipation box portion. A support rib is fixed in the heat dissipation box portion, and a cooling fan is installed on the support rib. An air outlet is opened on the side of the heat dissipation box portion on the top plate. A guide arc surface is provided between the edge of the heat dissipation box portion and the edge of the air outlet. An arc-shaped baffle is detachably connected above the air outlet on the top plate. The end of the arc-shaped baffle has an L-shaped baffle portion integrally formed with the arc-shaped baffle.

[0007] By adopting the above technical solution, the heat dissipation and heat insulation cover of the motor pump of this automotive active suspension system can achieve heat insulation and active heat dissipation functions for the motor pump. When the heat insulation cover is installed outside the motor pump in the automotive active suspension system, the top plate, the first side plate, and the second side plate can cover and enclose the motor pump to achieve heat insulation, and the protruding box can avoid other components in the automotive active suspension system. When the motor pump temperature is too high, the cooling fan set on the support rib can be activated to draw in air from the top of the cooling box and blow air out from the bottom. The air passes through the outside of the motor pump and can be blown out from the air outlet on the top plate, thereby carrying away the heat on the surface of the motor pump. The air speed is accelerated by the guide arc surface, which speeds up the heat dissipation. The arc-shaped baffle set above the air outlet and the L-shaped baffle located on the end of the arc-shaped baffle can guide the air blown out from the air outlet in a direction, blowing hot air out from the directional position and preventing debris from falling into the motor pump through the air outlet.

[0008] Preferably, the arc-shaped baffle has a vertical plate portion integrally formed with the arc-shaped baffle on the side opposite to the L-shaped baffle portion, and an outwardly protruding shoulder is fixed on the top plate portion, and the vertical plate portion and the outwardly protruding shoulder are detached and fixed.

[0009] By adopting the above technical solution, the arc-shaped baffle can be disassembled using the vertical plate and the outward protruding shoulder.

[0010] Preferably, a slot is provided on the protruding shoulder, and an insert that mates with the slot is fixed on the vertical plate.

[0011] By adopting the above technical solution, the fixing reliability of the vertical plate can be improved by using the cooperation of slots and inserts.

[0012] Preferably, the slot and the insert have trapezoidal cross sections.

[0013] By adopting the above technical solution, the slots and inserts with trapezoidal cross sections can improve the stability of mating.

[0014] Preferably, a first filter cloth is fixed to the top of the filter plate, and a second filter cloth is fixed to the bottom of the filter plate.

[0015] By adopting the above technical solution, the arrangement of the first filter cloth and the second filter cloth can improve the dust-proofing ability of the filter plate.

[0016] Preferably, a first fixing block is fixed on the heat dissipation box, and a second fixing block is fixed on the filter plate, with the first fixing block and the second fixing block connected by screws.

[0017] By adopting the above technical solution, the filter plate can be easily fixed to the heat sink box by using the first fixing block, the second fixing block and the screw.

[0018] Preferably, the first fixing block and the second fixing block are connected by a spring pin.

[0019] By adopting the above technical solution, the spring pin can facilitate the positioning of the first fixing block and the second fixing block.

[0020] Preferably, the heat dissipation box is frustoconical, and the edge where the heat dissipation box connects to the top plate is set as an arc surface.

[0021] By adopting the above technical solution, the arc-shaped surface design at the edge can increase wind speed.

[0022] Preferably, the top plate has several connecting ears on both sides.

[0023] By adopting the above technical solution, the connection ear design facilitates the installation and fixation of this heat insulation cover.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] The heat dissipation shield of the motor pump in this automotive active suspension system can achieve heat insulation and active heat dissipation for the motor pump. When the heat insulation shield is installed outside the motor pump in the automotive active suspension system, the top plate, the first side plate, and the second side plate can cover and insulate the motor pump, while the protruding box can avoid other components in the automotive active suspension system. When the motor pump temperature is too high, the cooling fan set on the support rib can be activated to draw in air from the top of the cooling box and blow air out from the bottom. The air passes through the outside of the motor pump and can be blown out from the air outlet on the top plate, thereby carrying away the heat on the surface of the motor pump. The air speed is accelerated by the guide arc surface, which speeds up the heat dissipation. The arc-shaped baffle set above the air outlet and the L-shaped baffle located on the side of the arc-shaped baffle can guide the air blown out from the air outlet in a direction, blowing hot air out from a directional position and preventing debris from falling into the air outlet and onto the motor pump.
