Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an engine mount mounting structure. Background Technology

[0002] The engine mount is a key component connecting the engine and the chassis. One of its core functions is to isolate and attenuate the transmission of engine vibrations to the vehicle body, thereby improving the vehicle's NVH performance. The mounting structure of the engine mount is crucial to its connection strength, reliability, and durability.

[0003] In traditional designs, suspension brackets are typically made of stamped or cast steel sheet metal. There are two common methods for creating threaded mounting holes in the bracket: one is to tap directly into the bracket body; the other is to weld or press a wire thread insert onto the bracket. However, both methods have significant drawbacks: 1. Direct Tapping: To ensure sufficient engagement length and strength of the threads, the wall thickness of the bracket at the mounting point must be sufficiently large. This is acceptable when there is ample installation space, but in modern automotive design, the engine compartment layout is increasingly compact, and installation space is often strictly limited. Increasing the overall thickness of the bracket simply to meet thread strength requirements will lead to material waste, increased weight, and potential interference with surrounding components.

[0004] 2. Welding / press-fitting of wire thread inserts: This process increases manufacturing steps and costs, and the welding quality may produce defects such as incomplete welds and porosity, affecting the reliability of the connection. Under long-term vibration loads, the weld joints may crack, causing the nut to loosen and posing a safety hazard.

[0005] Therefore, there is a contradiction in the existing technology: how to ensure that the suspension mounting point has extremely high threaded connection strength and reliability without significantly increasing the weight and volume of the bracket within a limited installation space.

[0006] This utility model patent aims to solve the above-mentioned contradictions and provide a compact, lightweight, and high-strength engine mount structure. Utility Model Content

[0007] To address the above issues, an engine mount structure is proposed.

[0008] The technical solution of this utility model is as follows: an engine mounting structure, including a bracket body, a mounting groove is provided at the connection between the bracket body and the engine, a first mounting surface and a second mounting surface are provided on the side of the mounting groove, the first mounting surface and the second mounting surface are symmetrically arranged and parallel to each other; the first mounting surface and the second mounting surface are connected to the inner side of the mounting groove by an inclined surface. It also includes a connector, which has a flange on its outer circumferential side. The connector is connected to the mounting groove by an interference fit through the flange, and the outer side of the connector is locked between the first mounting surface and the second mounting surface.

[0009] Preferably, the connector is a flange nut.

[0010] Preferably, the support body has a hollow structure inside.

[0011] The beneficial effects of this utility model are as follows: By using profiled aluminum and combining it with a pre-embedded standard nut in a contoured structure, the thread load-bearing task is transferred from the bracket body material to the high-strength standard nut. Therefore, there is no need to increase the overall wall thickness of the bracket to meet the thread engagement length, thus solving the installation strength problem in confined spaces.

[0012] Aluminum alloy profiles have low density and can be hollowed out, achieving significant weight reduction while maintaining structural rigidity, which helps reduce vehicle fuel consumption and emissions.

[0013] Using standard nuts, the thread strength, precision, and consistency are far superior to those obtained by directly tapping into aluminum. The pre-embedded fixing process ensures the nuts will not loosen under long-term vibration, resulting in high connection reliability.

[0014] Profile extrusion is a one-step forming process that is highly efficient and low-cost. The contoured structure can be integrally formed with the main profile body, reducing subsequent complex machining processes. The pre-embedded nut technology is also mature and reliable, resulting in low overall manufacturing costs. Attached Figure Description

[0017] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. This embodiment is based on the technical solution of the present invention and provides detailed implementation methods and specific operating procedures; however, the scope of protection of the present invention is not limited to the following embodiments.

[0018] refer to Figure 1 , 2 As shown in the figure, this application discloses an engine mount structure, including a bracket body 1. The bracket body 1 is formed by extrusion of aluminum alloy profile. The bracket body 1 has a hollow structure inside, with a hollow space inside to achieve lightweighting.

[0019] refer to Figure 1 , 3 As shown, a mounting groove 12 is provided at the connection between the bracket body 1 and the engine. The mounting groove 12 is a structure extending from the outer side of the bracket body 1. The side of the mounting groove 12 is provided with a first mounting surface 13 and a second mounting surface 14. The first mounting surface 13 and the second mounting surface 14 are symmetrically arranged and parallel to each other to prevent the nut from deflecting when the flange nut is twisted. The first mounting surface 13 and the second mounting surface 14 are connected to the inner side of the mounting groove 12 by an inclined surface.

[0020] refer to Figure 1 , 4 As shown, it also includes a connector 3, which is a flange nut. A flange 31 is provided on the outer circumference of the connector 3. The connector 3 is connected to the mounting groove 12 by an interference fit through the flange 31. The outer side of the connector 3 is stuck between the first mounting surface 13 and the second mounting surface 14.

[0021] The specific working principle is as follows: Select a standard flange nut as the connector 3. Through interference fit or special tooling, press the flange 31 of the connector 3 into the mounting groove 12. The outer side of the connector 3 is fixed between the first mounting surface 13 and the second mounting surface 14. The flange 31 of the connector 3 fits tightly with the mounting groove 12, providing additional anti-rotation and pressure-bearing area.

[0022] During installation, align the mounting holes of the engine mount with connector 3, pass the connecting bolt through the mount and screw it into connector 3, and tighten to complete a secure connection. Since all thread engagement occurs inside connector 3 with a high-strength standard nut, this connection point can still withstand the enormous vibrations and loads of the engine, even if the wall thickness of the bracket body 1 is relatively thin.

[0023] The beneficial effects are: This invention utilizes profiled aluminum and incorporates a pre-embedded standard nut in a contoured structure, transferring the thread load-bearing capacity from the bracket body material to the high-strength standard nut. Therefore, it eliminates the need to increase the overall wall thickness of the bracket to meet the thread engagement length requirement, thus solving the installation strength problem in confined spaces.

[0024] Aluminum alloy profiles have low density and can be hollowed out, achieving significant weight reduction while maintaining structural rigidity, which helps reduce vehicle fuel consumption and emissions.

[0025] Using standard nuts, the thread strength, precision, and consistency are far superior to those obtained by directly tapping into aluminum. The pre-embedded fixing process ensures the nuts will not loosen under long-term vibration, resulting in high connection reliability.

[0026] Profile extrusion is a one-step forming process that is highly efficient and low-cost. The contoured structure can be integrally formed with the main profile body, reducing subsequent complex machining processes. The pre-embedded nut technology is also mature and reliable, resulting in low overall manufacturing costs.
