DETAILED DESCRIPTION

[0017] The specific embodiments of the present application are further described below by comparing the drawings and the description of the embodiments, the purpose being to help the technicians in the field to have a more complete, accurate and deep understanding of the inventive concept and technical scheme of the present application, and to help them to implement the present application.

[0018] As Figures 1-2 shown, an engine suspension cross beam is arranged at one end of an automobile engine, comprising a cross beam 1, the cross beam 1 is connected with a supporting mechanism 2, and the supporting mechanism 2 is connected with the engine. The cross beam 1 is provided in two, the cross beams 1 are arranged side by side, the cross beam 1 is the main structural component of the engine suspension cross beam 1, and plays a basic role of bearing and connecting other related parts. The cross beam 1 provides a mounting base body for the supporting mechanism 2 and the like, the engine can disperse and transmit force to other parts such as the vehicle body through the supporting mechanism 2, so as to ensure that the engine is in a relatively stable position during the operation of the automobile.

[0019] ​The support mechanism 2 comprises a first fixing base 201 connected with the cross beam 1, and the first fixing base 201 is connected with a first reinforcing beam 202 abutting against the engine. By moving the connecting point of the first fixing base 201 and the cross beam 1 downward, the gravity center of the engine and its accessories is moved downward, the overall vehicle height is reduced, and the stability of the overall vehicle is improved. By moving the first reinforcing beam 202 and the first fixing base 201 downward, the mounting point of the engine is changed, the mounting point of the vehicle frame is moved downward to below the wing surface of the vehicle frame, so that the deficiency of the suspension in the Z-direction mounting space is avoided, the arrangement space of the pipeline is maximized, and the assembly is more convenient and efficient. The first reinforcing beam 202 is a round rod beam, which has excellent torsional capacity.

[0020] The first fixing base 201 comprises a first fixing plate 203 connected with the cross beam 1 and a first bent plate 204 connected at one end of the first fixing plate 203. The angle formed by the first fixing plate 203 and the first bent plate 204 is obtuse, which can better support the engine and support the engine by the first bent plate 204, avoid the deficiency of the suspension in the Z-direction mounting space, and maximize the arrangement space of the pipeline.

[0021] The first fixing base 201 is connected with a first reinforcing plate 205 between the cross beam 1, one end of the first reinforcing plate 205 is bent to form a second bent plate 206, and the first reinforcing plate 205 and the second bent plate 206 cooperate with the first fixing base 201. The first reinforcing plate 205 and the second bent plate 206 are connected between the first fixing base 201 and the cross beam 1, and mainly play a role in enhancing the structural strength of the connecting part of the first fixing base 201 and the cross beam 1. The first reinforcing plate 205 and the second bent plate 206 can effectively disperse the tension and pressure, prevent the connecting part from cracking, deforming and other damage, and the second bent plate 206 cooperates with the first fixing base 201 to further optimize the force transmission path.

[0022] The first weight-reducing hole 3 is formed in the cross beam 1. The first weight-reducing hole 3 helps to reduce the weight of the cross beam under the premise of ensuring that the cross beam has sufficient strength, is conducive to the lightweight design of the overall vehicle, reduces fuel consumption, and also does not have a great impact on the bearing and connecting functions.

[0023] The second weight-reducing hole 4 is arranged in the first reinforcing beam 202. The second weight-reducing hole 4 can reduce the weight of the first reinforcing beam 202, is conducive to the lightweight design of the overall vehicle, reduces fuel consumption, and also does not have a great impact on the bearing and connecting functions.

[0024] The cross beam 1 comprises a second fixed plate 101, and third bending plates 102 are bent at both ends of the second fixed plate 101. The third bending plates 102 bent at both ends of the second fixed plate 101 can increase the structural strength of the cross beam 1 itself, so that the cross beam 1 is not easy to deform when bearing the weight of the engine and various dynamic forces in the process of driving the automobile, and the rigidity of the overall structure is improved.

[0025] The first fixed plate 203 and the first bending plate 204 are in an integrated molding structure, so that the connection between the first fixed plate 203 and the first bending plate 204 is more stable, and the strength and stability are higher. The first reinforcing plate 205 and the second bending plate 206 are in an integrated molding structure, so that the connection between the first reinforcing plate 205 and the second bending plate 206 is more stable, and the strength and stability are higher. The second fixed plate 101 and the third bending plate 102 are in an integrated molding structure, so that the connection between the second fixed plate 101 and the third bending plate 102 is more stable, and the strength and stability are higher.

[0026] Effects of the embodiment

[0027] By moving the connection point of the first fixed seat 201 downward relative to the cross beam 1, the center of gravity of the engine and its accessories is lowered, the height of the whole vehicle is reduced, and the stability of the whole vehicle is improved. The first reinforcing beam 202 is connected to the first fixed seat 201, and the mounting point of the engine is changed, so that the mounting point of the frame is lowered to below the wing surface of the frame, so that the deficiency of the suspension in the Z direction is avoided, the layout space of the pipeline is maximized, and the assembly is more convenient and efficient.

[0028] The above has been described by way of example with reference to the drawings. Obviously, the specific implementation of the present application is not limited to the above-mentioned manner. Any non-essential improvement using the method concept and technical solution of the present application, or direct application of the above-mentioned concept and technical solution of the present application to other occasions without improvement, is within the protection scope of the present application.
