[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Reference Figure 1 - Figure 3The utility model provides an embodiment: an automobile frame engine suspension mounting plate assembly, including a left suspension reinforcement plate 1, a mounting hole 3 is opened inside the left suspension reinforcement plate 1, a reference hole 2 is opened inside the left suspension reinforcement plate 1, a right suspension reinforcement plate 14 is fixedly connected to the outer wall of the left suspension reinforcement plate 1, a welding auxiliary positioning hole 6 is opened inside the right suspension reinforcement plate 14, a left suspension mounting plate 15 is fixedly connected to the outer wall of the left suspension reinforcement plate 1, the mounting hole 3 is opened inside the left suspension mounting plate 15, a reference hole 2 4 is opened inside the left suspension mounting plate 15, a suspension mounting surface 11 is provided on the outer wall of the left suspension mounting plate 15, a reference hole 2 is opened inside the left suspension mounting plate 15, a right suspension mounting plate 8 is fixedly connected to the outer wall of the left suspension mounting plate 15, a welding positioning hole 5 is opened inside the right suspension mounting plate 8, and a clamping component is provided on the outer wall of the left suspension mounting plate 15;

[0022] Specifically, during the installation of the engine, reference hole 1 2, mounting hole 3, reference hole 2 4 and reference hole 3 12 are precisely designed and positioned to ensure that the external bolts can accurately pass through and fix the engine. In this way, the engine is firmly fixed in the desired position, thereby avoiding shaking or displacement that may occur during operation. At the same time, mounting hole 3 not only serves as a fixing hole for the bolt, but also as a positioning hole for welding. In this way, bolt fixing and welding fixing can be combined to further enhance the connection strength between the engine and the mounting plate assembly. Through welding, the engine and the mounting plate assembly can be more firmly connected, thereby greatly improving the stability of the entire structure.

[0023] Reference Figure 1 - Figure 3 The clamping assembly includes an arc-shaped mounting surface 13, which is arranged on the outer wall of the left suspension mounting plate 15, and the arc-shaped mounting surface 13 is arranged on the outer wall of the left suspension reinforcement plate 1; the outer walls of the left suspension reinforcement plate 1 and the right suspension reinforcement plate 14 are both provided with a matching surface 7; the outer walls of the left suspension reinforcement plate 1 and the left suspension mounting plate 15 are both fixedly connected with a welding piece 9, and the welding piece 9 is fitted with the matching surface 7; the outer walls of the right suspension mounting plate 8 and the right suspension reinforcement plate 14 are both fixedly connected with a welding piece 2 10, and the welding piece 2 10 is fitted with the matching surface 7; the interiors of the left suspension reinforcement plate 1 and the left suspension mounting plate 15 are both provided with a reference hole 3 12; the welding piece 1 9 is fitted with the welding piece 2 10;

[0024] Specifically, the mounting plate assembly fits tightly on the surface of the engine through the arc-shaped mounting surface 13. This arc shape not only improves the accuracy of the installation, but also effectively disperses the stress generated during the installation to prevent damage caused by stress concentration. At the same time, the arc-shaped mounting surface 13 can also adapt to slight differences in the surface shape of the engine, further enhancing the stability and reliability of the installation. Secondly, the mounting plate assembly is provided with mating surfaces 7 on both sides, and these mating surfaces 7 can be precisely fitted on other components inside the car. Effectively form a good connection with other components. This not only improves the stability of the installation, but also helps to reduce the generation of vibration and noise, thereby improving the driving comfort of the car. At the same time, welding piece 1 9 and welding piece 2 10 are precisely welded together to form a solid whole. This not only improves the structural strength of the mounting plate assembly, but also helps to prevent loosening or falling off that may occur during use.

[0025] Working principle: When the engine needs to be firmly fixed, the engine is fixed by external bolts through the reference hole 1 2, the mounting hole 3, the reference hole 2 4 and the reference hole 3 12 respectively. At the same time, the mounting hole 3, the welding positioning hole 5 and the welding auxiliary positioning hole 6 can all be positioning holes for welding, so as to facilitate the welding and fixing of the engine and the mounting plate assembly. Then, the left suspension reinforcement plate 1, the right suspension mounting plate 8, the right suspension reinforcement plate 14 and the left suspension mounting plate 15 are all connected and fixed to each other, so that the entire mounting plate assembly can be more firm, thereby strengthening the overall frame structure, so as to achieve a stable installation of the engine. The fixing effect improves the stability of the mounting plate assembly and ensures the safety of the engine. When the mounting plate assembly needs to be installed and fixed, the arc-shaped mounting surface 13 can be fitted on the surface of the engine, and the matching surfaces 7 on both sides can fit on other components inside the car, so that the mounting plate assembly can be fixed, and then welded together by welding piece 1 9 and welding piece 2 10, so that the entire mounting plate assembly can be more stable, thereby achieving the effect of further installing and fixing the engine. At the same time, it can also be more conveniently installed and fixed with other components inside the car, which improves the convenience of engine installation and extends the service life of the car.

[0026] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
