Description

TECHNICAL FIELD

[0001] The utility model relates to ECU support technical field, specifically for a kind of ECU support assembly. BACKGROUND

[0002] As important parts of medium and heavy-duty engines, electronic control units (ECU) are widely used in engine control systems. In traditional technology, ECU usually adopts on-board technology and is directly assembled on the engine body. To reduce the influence of vibrations generated during engine operation on ECU, most existing structures use flexible legs design, which adds elastic elements to the leg structure to isolate vibrations. Flexible legs are usually composed of metal springs or rubber shock pads, which can absorb part of external vibrations, thereby reducing the direct transmission of vibrations to ECU.

[0003] However, the existing flexible leg structure has certain limitations in actual use. Although its elastic elements can achieve a certain vibration isolation effect, this isolation effect is limited to reducing vibration transmission, and cannot effectively adjust the matching of vibration frequency and system natural frequency, so it cannot truly realize the shock absorption function. Especially when medium and heavy-duty engines are running, the engine vibration frequency is complex and variable, and the flexible leg is difficult to completely absorb vibration energy when facing high-frequency or low-frequency vibrations, resulting in that vibrations are still partially transmitted to ECU, affecting its stable operation.

[0004] In addition, the traditional flexible leg structure usually focuses on vibration isolation in design, ignoring other protection needs of ECU. For example, when the engine is running, ECU is not only subjected to vibrations, but also to impact forces, heat and other external actions. The existing structure has less consideration for anti-collision and heat dissipation performance, especially in high-temperature environments, the heat dissipation effect of ECU is poor, which may cause overheating of the device, further reducing the service life and operating efficiency. INVENTION CONTENTS

[0005] The utility model relates to a kind of ECU support assembly, specifically for the installation and protection of medium and heavy-duty engine electronic control unit (ECU). The support assembly solves the problems of only isolating vibrations, lacking tuning shock absorption function, insufficient protection capability and poor heat dissipation performance of flexible leg structure in prior art by improving flexible connection structure, shock absorption performance, anti-collision protection and heat dissipation design.

[0006] The utility model includes fixed seat, floating guard frame, first tuner, second tuner and heat dissipation bottom plate. Among them:

[0007] Flexible connection structure of first tuner and second tuner:

[0008] The first tuner is symmetrically arranged at two ends of the fixed seat, and the fixed seat is flexibly connected with the floating guard frame through the first tuner; and the heat dissipation bottom plate is symmetrically arranged with two lugs at two sides, and the two lugs are connected with the surface of the floating guard frame through two second tuners, so as to form the flexible connection between the lugs and the floating guard frame. Through the structure, the floating installation between the fixed seat, the floating guard frame and the heat dissipation bottom plate is realized, and a bidirectional tuning damping system is formed. By adjusting the counterweight tuning blocks in the first tuners and the second tuners and the arrangement form of the low-carbon steel sheet elastic links, the natural frequency of the system is changed, so that the natural frequency of the system is matched or close to the vibration frequency of the engine, thereby effectively absorbing and attenuating vibration energy and reducing the influence of vibration on the ECU.

[0009] Light frame and anti-collision design:

[0010] The floating guard frame is designed by using high-strength polyethylene material, and is in the form of a light frame. The structure is sleeved on the outer periphery of the fixed seat, the first tuner and the second tuner, not only provides support connection and support function, but also can absorb energy through deformation of the frame under the action of sudden impact force, so as to protect the ECU from external impact and improve the safety of the equipment.

[0011] Optimized design of heat dissipation:

[0012] The heat dissipation bottom plate is a metal member, and the surface of the heat dissipation bottom plate is uniformly distributed with heat dissipation holes. The heat dissipation holes can enhance air convection during engine operation, quickly take away heat generated during ECU operation, thereby improving heat dissipation performance, effectively reducing working temperature, prolonging service life and operation efficiency of the equipment.

[0013] Symmetrical structure and stability:

[0014] The first tuner and the second tuner are the same in structure, and each includes a fixed connection end, a tuning block and a movable connection end, and are symmetrically arranged at two ends of the fixed seat and the heat dissipation bottom plate. The surface of the tuning block is provided with a plurality of elastic links, and each elastic link is arranged in parallel.

[0025] To make the purpose, technical scheme and advantage of the utility model more clear and obvious, below combining with concrete embodiment and referring to the drawings, the utility model is explained in further detail.It needs to be explained that the embodiment of the utility model and the feature in the embodiment can be combined mutually in the case of not conflicting.

[0026] It is understood that these descriptions are only exemplary, and are not to limit the scope of the utility model.

[0027] Below combining the drawings Figures 1-4 Some embodiments of the utility model provide an ECU support assembly.

[0028] This utility model includes a fixed base 100, a floating protective frame 200, a first tuner 300, a second tuner 400, and a heat dissipation base plate 500.

[0029] The first tuner 300 is symmetrically arranged at both ends of the fixed base 100, and the two ends of the fixed base 100 are flexibly connected to the floating guard frame 200 through the first tuner 300. The heat dissipation base plate 500 has symmetrically arranged lifting lugs 510 on both sides. Each of the two lifting lugs 510 is connected to the surface of the floating guard frame 200 through two second tuners 400, thereby achieving a flexible connection between the lifting lugs 510 and the floating guard frame 200. The first tuner 300 and the second tuner 400 have the same structure, both including a fixed connection end 310, a tuning block 320, and a moving connection end 330. The surface of the tuning block 320 is provided with several elastic connecting strips 321, and the other end of each elastic connecting strip 321 is connected to the surface of the moving connection end 330 and the fixed connection end 310, respectively.

[0030] Specifically, the first tuner 300 and the second tuner 400 achieve an elastic support system through the counterweight structure of the tuning block 320 and the elastic connecting strips 321 on its surface. The flexible connection design of the first tuner 300 and the second tuner 400 includes key structures such as the fixed connection end 310, the tuning block 320, and the moving connection end 330. The tuning block 320, as a metal counterweight, together with the low-carbon steel sheets arranged parallel to the elastic connecting strips 321, constitutes the elastic support system. This elastic support system can not only absorb vibrations from the outside world, but also change the natural frequency of the system by adjusting the weight of the counterweight and the arrangement of the steel sheets, so that it matches or is close to the frequency of external vibrations, thereby achieving tuning and vibration reduction.

[0031] When external vibrations are transmitted to the ECU bracket, the vibration energy is first transmitted to the first tuner 300 and the second tuner 400 through the mounting bracket 100. Since the first tuner 300 and the second tuner 400 form an elastic connection structure through the combination of the tuning block 320 and the elastic connecting bar 321, this structure can absorb vibration energy and convert it into elastic deformation or internal friction, thereby attenuating the intensity of the vibration and reducing the impact on the ECU body.

[0032] like Figure 3As shown in the figure, the first tuner 300 is arranged in an inverted manner at both ends of the fixed seat 100, and the fixed connection end 310 and the movable connection end 330 of the first tuner 300 are fixedly connected with the surface of the fixed seat 100 and the floating guard frame 200 respectively; the fixed connection end 310 and the movable connection end 330 of the second tuner 400 are fixedly connected with the lug 510 and the surface of the floating guard frame 200 respectively. The symmetrical arrangement of the first tuner 300 and the second tuner 400 enables the bracket to simultaneously absorb vibrations in the horizontal direction and the vertical direction. Through the parallel distribution of the elastic connecting strips 321, the elastic support structure can provide greater flexible deformation capability in the horizontal direction, and in the vertical direction, the mass distribution of the structure is optimized through the counterweight tuning block 320, thereby reducing the transmission of vibrations in both directions.

[0033] As shown in the figure, Figure 4 The elastic connecting strips 321 are low-carbon steel sheet structures, and each elastic connecting strip 321 is arranged in parallel. By using low-carbon steel material and parallel arrangement, the elastic properties of the bracket are enhanced, so that it can adapt to complex vibration environment. At the same time, the tuning block 320 is a metal counterweight block structure, and the center is located on the symmetry axis of each elastic connecting strip 321. By optimizing the counterweight arrangement of the tuning block 320, the tuning and shock absorption performance of the bracket is further improved. By adjusting the mass of the counterweight block of the tuning block 320 and the thickness, number or arrangement spacing of the low-carbon steel sheet of the elastic connecting strip 321, the natural frequency of the bracket assembly can be adjusted to be close to or offset from the external vibration frequency, so as to achieve the purpose of tuning and shock absorption. When the natural frequency of the bracket assembly is close to the external vibration frequency, the flexible connection structure can absorb most of the vibration energy and effectively attenuate it, thereby achieving maximum isolation of vibration.

[0034] As shown in the figure, Figure 1 and Figure 2 The floating guard frame 200 is a high-strength polyethylene material member, which adopts a lightweight frame body structure and is sleeved on the outer periphery of the fixed seat 100, the first tuner 300 and the second tuner 400. The frame body design not only provides support and connection functions for the bracket, but also absorbs impact energy through elastic deformation of the frame body when subjected to external impact force, thereby providing good anti-collision protection performance for the ECU.

[0035] As shown in the figure, Figure 4 The heat dissipation bottom plate 500 is a metal material member, and the surface is uniformly distributed with heat dissipation apertures. Through the design of the heat dissipation apertures, the air convection effect is enhanced, so that the heat generated during engine operation can be dissipated from the ECU in time, thereby improving the heat dissipation performance, reducing the working temperature, and improving the operation efficiency and service life of the ECU.

[0036] The utility model discloses a flexible connecting structure of first tuner 300 and second tuner 400, realized the two -way tuning shock attenuation function, overcome the defect that only can isolate vibration of traditional flexible support foot structure, through the lightweight frame of floating guard frame 200 and the heat dissipation optimization design of heat dissipation bottom plate 500, provided the comprehensive performance promotion of ECU, can adapt to the shock attenuation, protection and heat dissipation demand under the complex working condition of medium -heavy -duty engine.
