Description

Technical Field

[0001] This utility model relates to the field of engine mount technology, specifically to an anti-vibration engine mount. Background Technology

[0002] Engine mounts are a critical but often overlooked component in automobiles. They are primarily responsible for securing the engine and transmission (and sometimes the subframe) and connecting them to the vehicle's chassis or frame. Its core function is not only "fixation," but more importantly, isolation of vibration and impact to ensure smooth and comfortable driving. Chinese Patent No. CN201920825207.0 provides a shock-absorbing engine mount, relating to the technical field of unmanned aerial vehicles (UAVs). This shock-absorbing engine mount consists of four fixed columns and two arc-shaped plates. An arc-shaped plate is fixedly installed between every two fixed columns, and correspondingly, two fixed columns and arc-shaped plates are also fixedly installed on the lower side. A limiting column is fixedly installed on one side of the mount, with a long groove inside. An airbag is fixedly installed on one side of the limiting column, and a vent pipe is fixedly installed on the other side. The other side of the vent pipe is fixedly connected to a protective mechanism. By setting a movable plate, when gas enters the inflatable airbag, it can expand outward from the base, thereby protecting the bottom of the engine and providing sufficient cushioning. By setting a limiting frame and a fan, the airflow flowing in from the long groove accelerates into the inflatable pipe, causing the inflatable airbag to expand rapidly and diffuse outward from the movable plate, protecting the engine.

[0003] Based on the above, the inventors have discovered the following problems: the above device can protect the bottom of the engine and provide sufficient cushioning for the engine, but it ignores the engine installation problem, and different brackets need to be replaced for different engine models, resulting in a limited range of applicability. Utility Model Content

[0004] The purpose of this invention is to provide an anti-vibration engine mount to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vibration-damping engine mount, comprising a chassis, the lower end of which is provided with several mounting bolts for connecting to a car frame; the upper end of the chassis is provided with a middle plate, the chassis and the middle plate being fixedly connected by bolts; a bidirectional threaded rod is horizontally provided on the upper end of the middle plate, the two ends of the bidirectional threaded rod being rotatably connected to the two sides of the middle plate, and the two ends of the bidirectional threaded rod passing through the middle plate and respectively fixedly connected to handles; a fixed plate located in the middle section of the bidirectional threaded rod is fixedly provided on the middle plate; the bidirectional threaded rod has two threaded sections with opposite directions of rotation, each threaded section being threadedly connected to a connecting shaft; each connecting shaft is rotatably connected to a connecting member, the connecting member being rotatably connected to a connecting block, the connecting block being fixedly connected to the lower end of a movable seat; two movable seats are arranged opposite to each other; the upper end of the movable seat is provided with several mounting bolts for connecting to the engine; sliders are provided on both sides of the movable seat, and the two sides of the middle plate are provided with sliding grooves adapted to the sliders, the sliders being slidably disposed in the sliding grooves.

[0006] Furthermore, a rubber pad is provided between the lower end of the middle plate and the upper end of the chassis.

[0007] Furthermore, a buffer plate is fitted onto the bolts connecting the chassis and the middle plate, and the buffer plate is located between the chassis and the middle plate.

[0008] Furthermore, a spring is provided between each of the connecting shafts and the fixed disc, and the spring is sleeved on the bidirectional threaded rod.

[0009] Furthermore, a damping structure is provided between the contact surfaces of the slider and the groove; and the slider and the groove are inclined relative to the horizontal plane.

[0010] Furthermore, a rotational damping structure is provided at the rotatable connection between the bidirectional threaded rod and the central plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the anti-vibration engine bracket is reasonable and has the following advantages: (1) This utility model innovatively provides a convenient spacing adjustment function through the cooperation of a two-way threaded rod, a connecting shaft, a connecting piece, a connecting block, and a movable seat slider with a middle plate groove; this design allows the spacing of the engine fixing points installed on the top of the movable seat to be continuously adjusted, perfectly adapting to the mounting bases of different engine models, completely solving the problem of frequent replacement of traditional brackets, greatly expanding the universality and applicability of the bracket, simplifying the installation process, and reducing the cost of use; (2) This utility model is designed with a multi-level collaborative buffer system that is progressively layered, effectively isolating and significantly attenuating the vibration and impact generated by the engine operation. First, the spring sleeved on the bidirectional threaded rod provides efficient axial elastic buffer. Second, the damping structure between the sliders on both sides of the movable seat and the inclined sliding groove contact surface continuously consumes vibration energy during the sliding process. Its inclination angle cleverly decomposes the vertical vibration force into a component force along the sliding groove direction, enhancing the damping effect and giving it a self-resetting tendency. Finally, the rubber pad between the middle plate and the chassis and the buffer plate on the connecting bolt together form a basic isolation layer that absorbs residual high-frequency vibration and impact energy. This multi-path, collaborative buffer design significantly improves the anti-shaking efficiency and ride comfort of the equipment. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-4 The present invention provides a technical solution as follows: Example: A vibration-damping engine mount includes a chassis 1, with several mounting bolts 2 at the lower end of the chassis 1 for connecting to a vehicle frame; a middle plate 3 is provided at the upper end of the chassis 1, and the chassis 1 and the middle plate 3 are fixedly connected by bolts; a bidirectional threaded rod 5 is horizontally arranged at the upper end of the middle plate 3, with both ends of the bidirectional threaded rod 5 rotatably connected to the two sides of the middle plate 3, and both ends of the bidirectional threaded rod 5 passing through the middle plate 3 and respectively fixedly connected to handles 6; a fixed plate 15 located in the middle section of the bidirectional threaded rod 5 is fixedly arranged on the middle plate 3; the bidirectional threaded rod 5 has... Two threaded sections with opposite directions of rotation are provided, each threaded section being threadedly connected to a connecting shaft 14; each connecting shaft 14 is rotatably connected to a connecting piece 7, and the connecting piece 7 is rotatably connected to a connecting block 11, the connecting block 11 being fixedly connected to the lower end of the movable seat 4; the two movable seats 4 are arranged opposite to each other; the upper end of the movable seat 4 is provided with several mounting bolts 2 for connecting the engine; the two sides of the movable seat 4 are provided with sliders 13, and the two sides of the middle plate 3 are provided with sliding grooves 9 that are adapted to the sliders 13, the sliders 13 being slidably disposed in the sliding grooves 9; The vibrations and shaking generated during engine operation are first transmitted to the movable seat 4, which is fixedly connected to it. The vibration causes the movable seat 4 to tend to move. The movement of the movable seat 4 is transmitted to the connecting member 7 through the connecting block 11 at its lower end. The connecting member 7 transmits the force to the connecting shaft 14. The connecting shaft 14 tends to move axially along the double-threaded rod 5. The spring 12, which is sleeved on the double-threaded rod 5 and located between the connecting shaft 14 and the fixed plate 15, is compressed or stretched to absorb the axial impact energy.

[0015] A rubber pad 8 is provided between the lower end of the middle plate 3 and the upper end of the chassis 1.

[0016] A buffer plate 10 is fitted on the bolts connecting the chassis 1 and the middle plate 3, and the buffer plate 10 is located between the chassis 1 and the middle plate 3; The residual vibration energy after being buffered by the four layers of the movable seat is transmitted to the middle plate 3. The rubber pad 8 between the middle plate 3 and the base plate 1 undergoes elastic deformation, absorbing and isolating high-frequency vibration and some impact. At the same time, the buffer plate 10 sleeved on the bolts connecting the base plate 1 and the middle plate 3 is squeezed between the base plate 1 and the middle plate 3, further providing buffering and shock absorption, and allowing small relative displacement.

[0017] Each of the connecting shafts 14 and the fixed disk 15 is provided with a spring 12, and the spring 12 is sleeved on the bidirectional threaded rod 5.

[0018] A damping structure is provided between the contact surfaces of the slider 13 and the slide groove 9; and the slider 13 and the slide groove 9 are inclined relative to the horizontal plane. When the movable seat 4 passively vibrates, the sliders 13 on both sides will inevitably slide within the groove 9. The damping structure, such as friction material or viscous medium, set between the contact surfaces of the sliders 13 and the groove 9 generates resistance, consumes vibration energy, and suppresses the rapid reciprocating motion, i.e., shaking, of the sliders 13 within the groove 9. The sliders 13 and the groove 9 are inclined relative to the horizontal plane, which converts the vertical component of the vibration into a force along the direction of the groove 9 and is absorbed by the damping structure. At the same time, the tilt angle also provides a certain tendency for self-resetting.

[0019] The bidirectional threaded rod 5 is provided with a rotation damping structure at the rotational connection between it and the middle plate 3. The vibration of the engine is also transmitted to the bidirectional threaded rod 5 through the connector 7 and the connecting shaft 14, attempting to cause its slight unintended rotation; the rotation damping structure set at the rotatable connection between the bidirectional threaded rod 5 and the central plate 3 provides rotational resistance, suppresses the slight rotation of the bidirectional threaded rod 5, prevents the position of the movable seat 4 from being accidentally shifted due to vibration, and consumes this part of the vibration energy.

[0020] Working principle: The bracket is fixed to the car frame by the mounting bolts 2 at the lower end of the chassis 1; then the engine is placed or initially positioned on the mounting bolts 2 at the upper end of the movable seat 4. According to the actual distance between the engine feet, either handle 6 at both ends of the double-threaded rod 5 is manually rotated; the handle 6 drives the double-threaded rod 5 to rotate at the rotating connection on both sides of the middle plate 3; since the double-threaded rod 5 has two threaded sections with opposite directions of rotation, when rotating, the two connecting shafts 14 threaded to the threaded sections at both ends will move synchronously in opposite directions along the axis of the double-threaded rod 5; the movement of the connecting shaft 14 drives the rotating connecting piece 7 on it to move, and the connecting piece 7 drives the connecting block 11 rotating at its other end to move. The connecting block 11 is fixedly connected to the lower end of the movable seat 4, thus pushing the movable seat 4 to move. The sliders 13 on both sides of the movable seat 4 are embedded in the corresponding sliding grooves 9 on both sides of the middle plate 3 and slide along the sliding grooves 9. The sliding connection between the sliders 13 and the sliding grooves 9 constrains the movement trajectory of the movable seat 4, ensuring that it moves along a predetermined path, such as... Figure 4 As shown, the two movable seats 4 move synchronously in opposite directions under the drive of the bidirectional threaded rod 5 until the mounting bolt 2 at their upper end is precisely aligned with the engine base. Then, the engine is fastened to the movable seat 4 with bolts, thus making this device adaptable to different models of generators.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
