[0034] The vehicle motor bracket 1 according to an embodiment of the present utility model will be described below with reference to the accompanying drawings.
[0035] like Figure 1-Figure 4 As shown, the vehicle motor bracket 1 according to the embodiment of the present utility model includes a metal frame 100 and a plurality of bushing assemblies 200 .
[0036] The upper part of the metal frame 100 is suitable for being installed on the suspension cushion 10 of the vehicle frame, and the lower part of the metal frame 100 is constructed with a front lower connecting plate portion 110 and a rear lower connecting plate portion 120, both of which are located below the metal frame 100 and are arranged at intervals along the front and rear, and both of which extend obliquely toward the center of the width direction of the vehicle frame, and both of which are constructed with mounting holes 103. Each bushing assembly 200 is arranged in the mounting hole 103, and the bushing assembly 200 is suitable for passing fasteners to install the vehicle motor 20.
[0037] For example, the side of the metal frame 100 away from the bushing assembly 200 is connected to the suspension pad 10 through fasteners, the suspension pad 10 is located at the bottom of the upper part of the metal frame 100, and the front lower connecting plate portion 110 and the rear lower connecting plate portion 120 are connected to the vehicle motor 20 through fasteners, wherein the suspension pad 10 and the vehicle motor 20 are located in different directions.
[0038] According to the vehicle motor bracket 1 of the embodiment of the utility model, the bushing assembly 200 is made of natural rubber material, which has good elasticity and vibration absorption performance. When the vehicle is running, the vibration generated by the vehicle motor 20 will be transmitted to the frame through the vehicle motor bracket 1, and the natural rubber material of the bushing assembly 200 can effectively absorb and damp these vibrations, preventing the vibration from being transmitted to other parts of the vehicle, thereby reducing the vibration and noise of the vehicle and improving driving comfort. At the same time, by reducing the amount and intensity of the vibration transmitted from the vehicle motor 20 to the frame, the bushing assembly 200 can reduce the noise level in the vehicle, provide a quieter driving environment, and improve the comfort and experience of the driver.
[0039] In addition, the vibration absorption effect of the bushing assembly 200 can reduce the instability factor caused by the vibration of the vehicle motor 1 during driving, and improve the stability and controllability of the vehicle, which has a positive impact on driving safety and driving stability.
[0040] Therefore, the vehicle motor bracket 1 according to the embodiment of the utility model has the advantages of improving the vibration isolation performance and driving comfort of the whole vehicle.
[0041] In some specific embodiments of the present invention, Figure 4 As shown, the bushing assembly 200 includes a bushing inner tube 210, a bushing outer tube 220 and an elastic member 230. The bushing outer tube 220 is inserted into the mounting hole, and the bushing inner tube 210 is located radially inside the bushing outer tube 220. The elastic member 230 is radially arranged between the bushing inner tube 210 and the bushing outer tube 220. The bushing inner tube 220 is suitable for inserting fasteners to install the vehicle motor 20.
[0042] By providing an elastic member 230 between the bushing inner tube 210 and the bushing outer tube 220, the overall elasticity of the bushing assembly 200 is increased, thereby improving the vibration absorption effect. When the vehicle motor 20 vibrates, the elastic member 230 can reduce the degree of vibration transmission to the frame, reduce the impact of vibration on the entire vehicle, and further improve the vibration isolation performance. At the same time, the bushing inner tube 220 is suitable for inserting fasteners to install the vehicle motor 20, and the elastic member 230 provided between the bushing inner tube 210 and the bushing outer tube 220 can ensure the stability of the vehicle motor 20 during installation. The elastic member 230 acts as a buffer and support, which can reduce shaking and instability during installation, ensure that the vehicle motor 20 is firmly installed, and improve safety.
[0043] In some specific embodiments of the utility model, the elastic member 230 is a rubber member, and the bushing inner tube 210 and the bushing outer tube 220 are both metal members. The bushing inner tube 210 and the bushing outer tube 220 can be made of cast steel, so that the bushing inner tube 210 and the bushing outer tube 220 have high strength and hardness, can provide good support and protection, and ensure the stability and durability of the entire structure on complex roads and harsh environments. The elastic member 230 is a rubber member, which has good elasticity and vibration absorption performance, can effectively absorb vibration and convert it into tiny heat energy, thereby reducing the transmission of vibration. The structure of the bushing inner tube 210 and the bushing outer tube 220 made of metal material can provide better support and stability, and the vibration absorption characteristics of the elastic member 230 made of rubber material can effectively isolate the vibration of the vehicle motor 20 from being transmitted to the frame, and the original first-level vibration isolation is changed to second-level vibration isolation, thereby improving the vibration isolation performance of the whole vehicle.
[0044] In some specific embodiments of the present invention, the elastic member 230 is vulcanized and formed into one piece with the bushing inner tube 210 and the bushing outer tube 220. During the assembly process, the elastic member 230 is first vulcanized on the bushing inner tube 210 and the bushing outer tube 220 to form a bushing assembly 200. A plurality of bushing assemblies 200 are integrally pressed into the mounting hole 101 of the vehicle motor bracket 1 by press-fitting. This structure can improve the rigidity and stability of the overall structure of the vehicle motor bracket 1, effectively reduce the deformation and looseness of the components, and improve its bearing capacity and service life.
[0045] In addition, the integrated structure formed by vulcanization can enhance the connection strength between the elastic member 230 and the bushing inner tube 210 and the bushing outer tube 220. After vulcanization, the rubber forms a strong bond with the metal parts, which is not easy to peel off, fall off or loosen, ensuring a reliable connection between the elastic member 230 and the bushing inner tube 210 and the bushing outer tube 220, and improving the stability and safety of the parts.
[0046] In some specific embodiments of the present invention, Figure 4 As shown, one axial end of the bushing outer tube 220 is constructed with a limiting portion 201 surrounding its outer circumference, and the limiting portion 201 is supported on the upper surface of the front lower connecting plate portion 110 and the rear lower connecting plate portion 120. The limiting portion 201 structure can ensure that the bushing outer tube 220 has a stable position and support during the installation process, preventing it from unnecessary shaking or displacement during operation. Through the support relationship between the limiting portion 201 and the front lower connecting plate portion 110 and the rear lower connecting plate portion 120, the correct position of the bushing outer tube 220 can be maintained, which helps to ensure the stability and safety of the entire vehicle motor bracket 1 structure.
[0047] In some specific embodiments of the present invention, Figure 3As shown, the axial length of the bushing inner tube 210 and the bushing outer tube 220 is greater than the thickness of the front lower connecting plate portion 110 and the rear lower connecting plate portion 120. Compared with the thickness of the front lower connecting plate portion 110 and the rear lower connecting plate portion 120, the longer axial length of the bushing inner tube 210 and the bushing outer tube 220 can provide a larger support area, increase the stability of the connection between the components, effectively prevent the vehicle motor bracket 1 from loosening or deformation during operation, and improve the reliability and strength of the bracket.
[0048] In some specific embodiments of the present invention, Figure 2 and Figure 3 As shown, the axial lengths of the bushing inner tube 210 and the bushing outer tube 220 are not less than the axial length of the elastic member 230 .
[0049] The longer axial length of the bushing inner tube 210 and the bushing outer tube 220 can ensure that the elastic member 230 can be fully wrapped and supported during installation, thereby providing better support and fixing effects. The elastic member 230 is evenly supported over the entire length range, which can more effectively absorb and alleviate the force caused by external impact or vibration, and enhance the stability and safety of the vehicle motor bracket 1.
[0050] In some specific embodiments of the present invention, Figure 2-Figure 4 As shown, the mounting holes 103 of the front lower connecting plate portion 110 are constructed in a plurality along the extension direction of the front lower connecting plate portion 110, and the mounting holes 103 of the rear lower connecting plate portion 120 are constructed in a plurality along the extension direction of the rear lower connecting plate portion 120. The plurality of mounting holes 103 of the front lower connecting plate portion 110 and the rear lower connecting plate portion 120 are evenly spaced and symmetrical to each other. The plurality of mounting holes 103 structures ensure a stable connection between the vehicle motor 20 and the vehicle motor bracket 1, while the spacing between the plurality of mounting holes 103 can increase the contact area between the vehicle motor bracket 1 and the vehicle motor 1, thereby improving the reliability of the connection between the two. At the same time, the plurality of mounting holes 103 can disperse the stress applied by the vehicle motor 1, reduce the risk of structural damage or deformation caused by excessive force on a single fixed point, and improve the stability and bearing capacity of the vehicle motor bracket 1.
[0051] In some specific embodiments of the present invention, Figure 2-Figure 4 As shown, the metal frame 100 includes a transverse plate portion 101 and a side plate portion 102. The transverse plate portion 101 extends horizontally and is suitable for being installed on the suspension cushion 10 of the vehicle frame. The thickness of the side plate portion 102 gradually decreases from the transverse plate portion 101 to the bottom. The side plate portion 102 is connected to one side of the transverse plate portion 101 and is located on the inner side of the suspension cushion 10. The side plate portion 102 extends downward, and a front lower connecting plate portion 110 and a rear lower connecting plate portion 120 are formed on the side plate portion 101.
[0052] The structure in which the thickness of the side plate portion 102 gradually decreases downward along the transverse plate portion 101 can effectively reduce the weight of the entire vehicle motor bracket 1 while maintaining sufficient structural strength and improving the overall stability and load-bearing capacity. This structure can reduce unnecessary weight while meeting the structural strength requirements, which is beneficial to improving the performance of the vehicle motor bracket 1. At the same time, the transverse plate portion 101 and the side plate portion 102 can be bent at a certain angle, increasing the contact area with the vehicle motor 20 during the connection process with the vehicle motor 20, thereby improving the reliability and stability of the connection between the vehicle motor bracket 1 and the vehicle motor 20.
[0053] In addition, the side plate portion 102 extends downward to form a front lower connecting plate portion 110 and a rear lower connecting plate portion 120, which can effectively share the external load on the vehicle motor bracket 1, reduce the local bearing area, improve the overall deformation resistance of the vehicle motor bracket 1, and extend the service life of the bracket.
