Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a mounting bracket, particularly an engine mounting bracket. Background Technology

[0002] Currently, the automotive industry is experiencing rapid technological advancements, particularly with the application of various electronic control technologies, enabling the automobile to achieve leaps and bounds since its inception. Modern automotive products face increasingly higher quality requirements, and consumers have higher expectations and demands for automobiles. The economy, power, and warranty aspects of automobiles pose significant challenges to the development of the automotive industry.

[0003] With increasing demands for automotive comfort, more and more users are placing higher requirements on vehicle comfort, making engine noise reduction technology increasingly urgent. Therefore, using high-performance engine mounts is in line with market demand. For example, a composite vibration-damping engine mount disclosed in Chinese patent literature (application number: 201520583784.5) includes a shovel-shaped curved lower bracket and an L-shaped upper bracket. One end of the lower bracket has an anti-collision pad, and the upper surface of the upper bracket has a positioning pin for supporting and connecting the engine. A lower bracket rubber block is installed on the plate surface at the other end of the lower bracket, and a lower support spring is installed inside the lower bracket rubber block. A Y-shaped mount seat is installed inside the lower support spring, and both ends of the mount seat have arc-shaped feet that extend upwards through the upper bracket. The upper end of the arc-shaped feet has an extension edge, and an upper support spring is installed between the extension edge and the upper bracket. However, this engine mount mainly relies on spring vibration damping, so its damping effect is not ideal, and the damping fails after prolonged use, affecting its performance. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an engine mount with good vibration damping effect and long service life.

[0005] The objective of this utility model can be achieved through the following technical solution: an engine mount, including a cylindrical outer bracket, wherein an inner core assembly is fixedly connected inside the outer bracket, characterized in that the inner core assembly includes a connecting seat, a rubber sleeve, an inner cylinder, a flow channel body, and a bottom membrane, the upper and lower ends of the rubber sleeve are respectively connected to the upper end of the inner cylinder and the lower end of the connecting seat, the lower end of the inner cylinder is fixedly connected to the bottom membrane, the flow channel body divides the cavity of the inner cylinder into an upper cavity and a lower cavity, the flow channel body is provided with a flow channel that can connect the upper cavity and the lower cavity, the flow channel body is annular and a decoupling membrane is fixedly connected to the middle of the flow channel body, and the cavity of the inner cylinder is filled with buffer solution.

[0006] The engine's external bracket is fixed to the car chassis, and the connecting seat is fixed to the engine housing. The engine's vibration is transmitted to the buffer through the rubber sleeve. The rubber sleeve deforms to achieve buffering and shock absorption. The buffer squeezes the decoupling membrane to deform, achieving buffering and shock absorption. The buffer located in the upper cavity is squeezed into the lower cavity through the flow channel of the flow channel body. The buffer squeezes the bottom membrane, causing the bottom membrane to undergo elastic deformation, achieving buffering and shock absorption. It has the advantages of good vibration filtering effect and long service life.

[0007] In the aforementioned engine mount, the flow channel body has an annular groove in its center, and the annular groove is coaxially arranged with the flow channel body. An annular support is embedded on the outer side of the decoupling membrane, and the support wraps around the decoupling membrane. The support is positioned along the edge of the decoupling membrane, and the outer edge of the decoupling membrane is embedded in the annular groove. This configuration increases the connection strength between the decoupling membrane and the flow channel body, preventing the decoupling membrane from detaching.

[0008] In the aforementioned engine mount, a vertically arranged stud is inserted through the center of the connecting seat, and the stud extends out of the upper end face of the connecting seat. The connecting seat is fixedly connected to the engine via the stud, offering advantages such as convenient connection and simple structure.

[0009] In the aforementioned engine mount, the upper end of the outer bracket is provided with an annular anti-collision pad, and the upper end of the connecting seat extends beyond the anti-collision pad. The anti-collision pad improves the buffering effect during the connection of the outer bracket and reduces noise.

[0010] In the aforementioned engine mount, the outer side of the base membrane is provided with an annular deformation section that protrudes downwards. By providing the deformation section, the deformation range of the base membrane is increased, thereby improving the shock absorption effect.

[0011] In the aforementioned engine mount, the cross-section of the deformed portion is triangular.

[0012] In the aforementioned engine mount, a second support is provided along the outer edge of the base membrane. The second support is ring-shaped and arranged along the edge of the base membrane. By providing the second support, the connection strength of the base membrane is improved, and the sealing performance is enhanced.

[0013] In the aforementioned engine mount, the lower end of the inner cylinder has an inwardly bent portion that abuts against the outer side of the bottom membrane. Positioning the bottom membrane at the lower end of the inner cylinder via the bent portion provides advantages such as good sealing and reliable connection.

[0014] In the aforementioned engine mount, the outer wall of the outer bracket is provided with several support feet, and each support foot has a through hole for screws to pass through. These support feet facilitate the connection of the outer bracket, offering advantages such as simple structure and convenient connection.

[0015] Compared with existing technologies, this engine mount has the following advantages:

[0016] 1. The vibration of the engine is transmitted to the buffer through the rubber sleeve. The rubber sleeve deforms to achieve buffering and shock absorption. The buffer squeezes the decoupling membrane to deform and achieve buffering and shock absorption. The buffer in the upper cavity is squeezed into the lower cavity through the flow channel of the flow channel body. The buffer squeezes the bottom membrane, causing the bottom membrane to undergo elastic deformation, thus achieving buffering and shock absorption. It has the advantages of good vibration filtering effect and long service life.

[0017] 2. An annular support is embedded on the outside of the decoupling membrane. The support wraps around the decoupling membrane and is set along the edge of the decoupling membrane. The outer edge of the decoupling membrane is embedded in the annular groove to increase the connection strength between the decoupling membrane and the flow channel body and prevent the decoupling membrane from falling off.

[0018] 3. The upper end of the outer bracket is equipped with a ring-shaped anti-collision pad, and the upper end of the connecting seat extends out of the anti-collision pad, which improves the buffering effect when the outer bracket is connected and reduces noise.

[0019] 4. The outer side of the bottom membrane is provided with an annular deformation section that protrudes downward, increasing the deformation of the bottom membrane and thus improving the shock absorption effect. Attached Figure Description
