Description

Technical Field

[0001] This utility model relates to the field of engine bracket technology, and in particular to a multi-layer composite structure engine bracket. Background Technology

[0002] Multi-layer composite engine mounts are advanced engine support components. They typically consist of a metal base layer, a buffer layer, and a protective layer. The metal base layer provides stable support, ensuring it can withstand the weight of the engine and various forces generated during operation. The buffer layer, usually made of elastic materials such as rubber, effectively absorbs engine vibration, reducing the transmission of vibration and noise to the vehicle body and improving ride comfort. The protective layer protects the mount from corrosion and wear from the external environment, extending its service life. This type of mount combines the advantages of multiple materials and is widely used in the automotive industry, contributing to improved overall vehicle performance and quality. However, current multi-layer composite engine mounts vibrate during engine operation, causing noise and leading to abnormal vehicle rattles, thus requiring improvement. Utility Model Content

Each vibration damping mechanism includes a mounting groove 2 disposed within the bracket body 1 for component mounting; a mounting plate 3 disposed within the mounting groove 2 and fixedly connected to it; multiple connecting members 4 disposed on and fixedly connected to the mounting plate 3; two connecting shafts 5 disposed on and rotatably connected to the connecting members 4; two rotating members 6 disposed on and fixedly connected to the connecting shafts 5; two connecting blocks 7 disposed on and fixedly connected to the rotating members 6; and a buffer mechanism disposed within the bracket body 1 for buffering and engine connection operations.

[0051] refer to Figure 1 and Figure 5 In a preferred embodiment, the vibration damping mechanism further includes: two first springs 8, which are disposed within the connecting block 7 and fixedly connected to the connecting block 7; a first rubber plate 9, which is disposed on the first springs 8 and fixedly connected to the first springs 8; and multiple third springs 16, which are disposed between the mounting plate 3 and the rotating member 6 for supporting both sides of the rotating member 6.

[0052] With this configuration, one end of the rotating member 6 can contact the second rubber plate 17. When the rotating member 6 rotates, it can apply a reverse force to the second rubber plate 17, thereby offsetting part of the force generated by vibration, thus preventing the device and engine from vibrating and generating noise. The first spring 8 and the first rubber plate 9 can absorb part of the vibration. The third spring 16 is used to support the rotating member 6 and to allow the rotating member 6 to rotate with the vibration of the engine.

[0053] refer to Figure 2 and Figure 3 In a preferred embodiment, the buffer mechanism includes: a connecting device disposed within the support body 1 for fixing the support body 1 and connecting to the engine; and a buffer device disposed within the support body 1 for buffering and shock absorption.

[0054] refer to Figure 3In a preferred embodiment, the connecting device includes: a plurality of first connecting holes 11 disposed within the bracket body 1 for fixing the bracket body 1; a plurality of second connecting holes 12 disposed within the bracket body 1 for connecting and fixing the engine; and a plurality of heat insulation components 13 disposed within the bracket body 1 for protecting the first connecting holes 11 and the second connecting holes 12.

[0055] In this configuration, the first connecting hole 11 is used for mounting and fixing the bracket body 1 and the vehicle body; the second connecting hole 12 is used for fixing the engine; and the heat insulation component 13 is used to insulate the positions of the first connecting hole 11 and the second connecting hole 12 to prevent the fixing bolts installed in the first connecting hole 11 and the second connecting hole 12 from overheating and causing unstable connection.

[0056] refer to Figure 1 In a preferred embodiment, the buffer mechanism includes: a mounting part disposed on the support body 1 for component mounting; and a buffer part disposed on the mounting part for buffering operation.

[0057] refer to Figure 4 In a preferred embodiment, the mounting part includes: a plurality of fixing grooves 14, which are disposed within the bracket body 1 for component mounting; and a support ring 15 disposed on the bracket body 1 and fixedly connected to the bracket body 1.

[0058] refer to Figure 4 In a preferred embodiment, the buffer includes: a plurality of third springs 16, wherein the plurality of third springs 16 are disposed in the fixing groove 14 and fixedly connected to the fixing groove 14; and a second rubber plate 17, disposed on the third springs 16 and fixedly connected to the third springs 16.

[0059] In this configuration, the fixing groove 14 is used to fix the third spring 16 in place; the third spring 16 is used to work with the second rubber plate 17 to buffer the vibration generated by the engine and prevent the device and the engine from resonating and generating noise.

[0060] This device, by incorporating a vibration damping mechanism, allows engine vibrations to be redirected back onto the device's internal components during mounting, partially offsetting the engine's vibrations and preventing resonance between the device and the engine, thus reducing noise. Furthermore, the device's buffer mechanism not only secures the device to the engine but also provides heat insulation protection for the mounting bolts, preventing overheating and instability. It also buffers engine vibrations during operation, further reducing noise.

[0061] Working principle: When in use, this device is fixed in the required position through the first connecting hole 11 and using fixing bolts. Then, the engine is fixed to the device through the second connecting hole 12 and using fixing bolts. When the engine is running, the engine vibrates. When the engine vibrates, the second rubber plate 17 compresses the third spring 16, thus buffering and damping the vibration. At the same time, when the engine vibrates, it comes into contact with the first rubber plate 9, which compresses the first spring 8, thereby damping the vibration. Simultaneously, the rotating part 6 rotates, compressing or stretching the second spring 10. The rotating part 6 then applies a reverse force to the second rubber plate 17, counteracting the vibration generated by the engine and preventing resonance.

[0062] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
