Description
Technical Field
[0001] This utility model belongs to the field of motor technology, specifically relating to a heat insulation cover for a motor pump of an active suspension system for automobiles. Background Technology
[0002] The electric motor pump in an active suspension system is the core power component, primarily used to adjust suspension parameters such as stiffness and damping. The hydraulic pump is mainly 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 of each wheel. This system is relatively large and is typically installed between the two axles, providing power to the suspension on both sides via hydraulic lines.
[0003] The active suspension motor pump is affected by the heat from the engine / exhaust pipe, which reduces the performance of the motor pump. Therefore, a heat shield is installed.
[0004] The current heat shield is directly sealed and fixed to the outside of the active suspension motor pump. This method has some drawbacks, such as: although the heat shield has the function of heat insulation, it cannot achieve directional heat dissipation to protect the motor pump. Utility Model Content

The top plate, the first side plate, and the second side plate can protect and insulate the motor pump. The outwardly protruding box can avoid the critical position of the motor pump. The heat exchange function of the motor pump can be realized by using the directional ventilation structure. Directional heat dissipation can be achieved through the directional slots, preventing the hot air discharged from the engine exhaust pipe from blowing directly onto the motor pump through the slots. This avoids the impact of overheating heat emitted by the motor pump on other components in the automotive suspension system, thereby improving service life. The L-shaped baffle, end baffle, and air guide plate can accelerate the airflow circulation in the directional ventilation channel, thereby achieving directional heat dissipation and preventing the motor pump from being damaged in critical positions.

[0010] Preferably, the openings of the two directional ventilation structures are opposite in direction.
[0011] By adopting the above technical solution, the opening directions of the two directional ventilation mechanisms are set to be opposite to each other, preventing the openings of the two directional ventilation structures from facing each other and causing the discharged hot airflow to affect each other and reduce the heat exchange efficiency.
[0012] Preferably, the top plate has raised ribs.

[0019] By adopting the above technical solution, the setting of the clearance gap can avoid the critical position of the motor pump.
[0020] Preferably, the first side plate and the second side plate are respectively provided with waist-shaped mounting grooves.
[0021] By adopting the above technical solution, the waist-shaped mounting groove can facilitate the installation and fixation of the first side plate and the second side plate.
[0022] Preferably, the surfaces of the top plate, the first side plate, and the second side plate are each provided with a heat-insulating coating.

The top plate, first side plate, and second side plate protect and insulate the motor pump. The protruding box avoids the motor pump's critical locations. A directional ventilation structure enables heat exchange for the motor pump. Directional slots facilitate directional heat dissipation. L-shaped baffles, end baffles, and air guides accelerate airflow circulation within the directional ventilation channel, preventing hot air from the engine exhaust pipe from directly blowing onto the motor pump and avoiding damage to critical locations. The heat shield is easily installed and secured using connecting pieces and threaded holes. Furthermore, the "C"-shaped heat shield features an open opening, allowing airflow to enter and exit the directional ventilation structure during vehicle operation. This rapid airflow facilitates heat dissipation, and the directional ventilation structure reduces air resistance and noise generation. Attached Figure Description

Detailed Implementation
[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0037] Please see Figures 1 to 4This utility model provides a technical solution: a heat shield for an active suspension system motor pump in an automobile. This heat shield can be applied to the outside of the motor pump in the active suspension system, serving two functions: protecting the motor pump and providing directional heat dissipation to prevent heat from affecting the lifespan of the components. To achieve these two functions, the heat shield is constructed using an integrally formed top plate 1, a first side plate 2, and a second side plate 3, which can be directly fitted and installed on the outside of the suspension system motor pump. To avoid the structure on the suspension system's motor pump, the top plate 1 has an integrally formed protruding box 4, which avoids the protruding structure on the motor pump. Simultaneously, the top plate 1 is also equipped with two directional ventilation structures, each including a slot 5, an L-shaped baffle 6, two end baffles 7, and an air guide plate 8. The slot 5 is located on the top plate 1, the L-shaped baffle 6 is located on one side of the slot 5, the two end baffles 7 are fixed to the two ends of the L-shaped baffle 6, and the air guide plate 8 is fixed to the two end baffles 7. A directional ventilation channel 9 is formed between the air guide plate 8 and the L-shaped baffle 6. During vehicle operation, airflow enters through the open opening of the C-shaped heat shield and flows out through the directional ventilation channel 9, carrying away heat and achieving directional heat dissipation. To facilitate the installation of the heat shield, connecting pieces 10 are welded and fixed to both sides of the top plate 1, and threaded holes 11 are provided on the connecting pieces 10.
[0038] Please see Figures 1 to 4 The heat shield of the motor pump in this automotive active suspension system can achieve heat insulation. The top plate 1, the first side plate 2, and the second side plate 3 can protect and insulate the motor pump. The outwardly protruding box 4 can avoid the critical position of the motor pump. The heat exchange function of the motor pump can be realized by using the directional ventilation structure. Directional heat dissipation can be achieved through the directional slots 5. The L-shaped baffle 6, the end baffle 7, and the air guide plate 8 can accelerate the airflow circulation in the directional ventilation channel 9, thereby achieving directional heat dissipation and preventing the motor pump from being damaged in critical positions. The heat shield can be easily installed and fixed by using the connecting piece 10 and its threaded hole 11.
[0039] Please see Figures 1 to 4 In order to achieve directional ventilation, the air guide plate 8 includes a vertical section 81, an inclined curved section 82 and a horizontal section 83. The vertical section 81 is fixed to the top plate 1, the inclined curved section 82 is located between the vertical section 81 and the horizontal section 83, and the horizontal section 83 is parallel to the top of the L-shaped partition 6. The arrangement of the vertical section 81, the inclined curved section 82 and the horizontal section 83 can accelerate the airflow, thereby achieving directional heat dissipation.
[0040] refer to Figure 1 and Figure 4Preferably, the opening directions of the two directional ventilation structures are set to be opposite to each other to prevent the hot airflows discharged from the two directional ventilation structures from affecting each other and reducing heat exchange efficiency when the openings are opposite. Furthermore, this heat insulation cover has raised ribs on the top plate portion 1, and raised ribs are provided between the top plate portion 1 and the first side plate portion 2 and the second side plate portion 3 to enhance strength. By utilizing the raised ribs on the top plate portion 1, the bending section modulus and torsional section modulus of the top plate portion can be increased. This improves stiffness and reduces vibration and noise.
[0041] refer to Figure 4 and Figure 5 Because the heat shield of the active suspension system motor pump directly covers the outside of the suspension system motor pump, a certain gap can be reserved between the suspension system motor pump and the heat shield to achieve heat insulation and directional heat dissipation. This gap allows for heat dissipation, as detailed in the instruction manual. Figure 5 The arrows in the diagram indicate that ventilation and heat dissipation can be achieved through the directional air exchange duct 9, preventing hot air from the engine exhaust pipe from blowing directly onto the motor pump through the slot 5. Because the air guide plate 8 includes a vertical section 81, an inclined curved section 82, and a horizontal section 83, it can convert direct vertical heat dissipation into horizontal heat dissipation to both sides, achieving a directional heat dissipation effect. Since the opening of the directional air exchange duct 9 is large at one end and small at the other, it can form vortices, accelerating airflow. The streamlined directional air exchange duct 9 achieves good ventilation. Furthermore, the "C"-shaped heat shield used in this application has an open opening, allowing airflow to flow in through the open opening and out through the directional air exchange structure, achieving rapid dissipation through the flowing air. Moreover, since increased air resistance, vibration, or noise are inevitable during vehicle operation, the directional air exchange structure in this heat shield can discharge the airflow entering through the open opening, reducing air resistance and noise generation.
[0042] Please see Figures 1 to 4 To facilitate the installation and fixing of this heat insulation cover, the connecting piece 10 is designed in an L-shape with rounded corners in the middle. The L-shape allows for easy installation and fixing. The first side plate 2 has a clearance notch, which is trapezoidal and allows for clearance around critical positions of the motor and pump. The first side plate 2 and the second side plate 3 each have a waist-shaped mounting groove 12, which facilitates the installation and fixing of both side plates.
[0043] Please see Figures 1 to 4To improve thermal insulation performance, a thermal insulation coating is applied to the surfaces of the top plate 1, the first side plate 2, and the second side plate 3. This coating enhances the thermal insulation effect of the top plate 1, the first side plate 2, and the second side plate 3. Thermal insulation strips 13 are provided around the two slots 5 of the top plate 1, improving the thermal insulation effect at the slots 5. The thermal insulation strips 13 are U-shaped and are made of expanded polystyrene. Expanded polystyrene strips have good thermal insulation properties, thus improving the overall thermal insulation effect.
