Description

Technical Field

[0001] This utility model relates to the field of engine technology, specifically to an engine linkage shock absorber foot. Background Technology

[0002] As the core power source of equipment such as automobiles, generator sets, and construction machinery, the engine generates complex multi-dimensional vibrations during its operation due to the reciprocating motion of the piston, the rotational inertia of the crankshaft, and the explosive force of combustion. These vibrations include both low-frequency rigid body vibrations and high-frequency elastic vibrations of components. If these vibrations are directly transmitted to the equipment body or frame through rigid connections, they will cause a series of problems. Therefore, an engine-connected shock-absorbing mount is needed.

[0003] Existing engine linkage damping mounts, when in operation, mostly use a single elastic element + fixed structure design, which makes it difficult to suppress vibrations in multiple directions. For example, some vehicle mounts are designed to bear weight, which filters vertical vibrations well, but has weak damping capacity for lateral and torsional vibrations. This causes vibrations to be transmitted through the vehicle frame and form resonance noise. The connection is a single fixed design, which makes it impossible to suppress vertical vibration and displacement of the engine and avoid large lurching problems when the engine starts, accelerates or bumps. Therefore, there is an urgent need for a new type of engine linkage damping mount. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide an engine linkage shock absorber mount to solve the problem that most traditional engine linkage shock absorber mounts use a single elastic element + fixed structure design, which makes it difficult to suppress vibrations in multiple directions. For example, some vehicle mounts are designed to bear weight, which filters vertical vibrations well, but has weak damping capacity for lateral and torsional vibrations. This causes vibrations to be transmitted through the vehicle frame and form resonance noise. The connection is a single fixed design, which makes it impossible to suppress the vertical vibration and displacement of the engine and avoid the problem of large lurching when the engine starts, accelerates or bumps.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an engine linkage shock absorber foot, including a base, a damper fixedly connected to the inner wall of the base, a damping rod installed on the inner wall of the damper, a buffer spring installed on the outer wall of the damping rod, a pressing plate fixedly connected to the top of the damping rod, and a slider installed on the side wall of the pressing plate.

[0006] The top of the slider is provided with a connecting plate, the inner wall of the connecting plate is provided with a sleeve rod, the inner wall of the sleeve rod is installed with a telescopic rod, and the top of the telescopic rod is fixedly connected with a pressure plate.

[0007] Preferably, the buffer spring is sleeved with the damping rod, and the damping rod is sleeved with the damper.

[0008] Preferably, both the slider and the extrusion plate are connected to the base via a buffer spring to form a telescopic structure, and the extrusion plate is symmetrically arranged about the central axis of the base.

[0009] Preferably, the pressure plate forms a telescopic structure through a telescopic rod and a sleeve rod, and the telescopic rod and the sleeve rod are inserted into each other.

[0010] Preferably, the surface of the pressure plate is provided with anti-slip texture, and the pressure plate is movably connected to the connecting plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the setting of dampers, damping rods, buffer springs, compression plates and sliders, overcomes the limitations of traditional devices that only reduce vibration in one direction and cannot cope with vibration in a single direction. The damping effect is not comprehensive enough. However, when the engine is subjected to vibration, the dampers, damping rods and buffer springs on the left and right sides and the bottom can buffer and absorb the vibration force. At the same time, the vibration reduction structure is designed for the vertical and lateral vibration of the engine, which solves the limitation of traditional engine feet that can only cope with vibration in one direction, avoids insufficient vibration reduction in one direction, has a wider range of applications and a more comprehensive vibration reduction effect. 2. This utility model, through the setting of a connecting plate, sleeve rod, telescopic rod, and pressure plate, clamps the engine connection point using the pressure plate and connecting plate. Compared with the traditional single fixed design of engine mounts, it can improve the connection rigidity, while accurately suppressing the vertical vibration and displacement of the engine, avoiding large surging during engine start-up, acceleration, or bumps. It can also make the vibration damping components more evenly stressed, extend their service life, reduce the transmission of resonance noise to the vehicle body, and improve the stability of the connection. At the same time, it does not affect the normal thermal expansion and contraction displacement of the engine. Furthermore, the extension and retraction adjustment of the sleeve rod and telescopic rod can accommodate engine connection points of different thicknesses. Attached Figure Description

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0015] The embodiments of this utility model will be described below based on its overall structure.

[0016] Please see Figures 1-4 An engine-connected shock absorber foot includes a base 1, a damper 2 fixedly connected to the inner wall of the base 1, a damping rod 3 installed on the inner wall of the damper 2, a buffer spring 4 installed on the outer wall of the damping rod 3, a compression plate 5 fixedly connected to the top of the damping rod 3, and a slider 6 installed on the side wall of the compression plate 5. The buffer spring 4 is sleeved with the damping rod 3, and the damping rod 3 is sleeved with the damper 2. Both the slider 6 and the compression plate 5 form a telescopic structure with the base 1 through the buffer spring 4, and the compression plate 5 is symmetrically arranged about the central axis of the base 1. When the device is in use, when the engine is subjected to vibration, it is transmitted to a connecting plate 7. The connecting plate 7 transmits the vibration force to the vertical slider below without loss through a rigid connection. Block 6, at this time, the vertical slider 6 is subjected to a downward impact force. Under the action of the impact force, the vertical slider 6 moves downward along the vertical track of the base 1. Its bottom directly presses against the extrusion plate 5 below. After the extrusion plate 5 is subjected to vertical pressure, it contacts the inclined surface of the horizontal slider 6 through the inclined surfaces on both sides, converting the vertical force into a horizontal outward thrust, driving the horizontal sliders 6 on both sides to move along the horizontal track of the base 1 towards the damper 2. At the same time, when the vertical slider 6 moves downward, it will also push the vertical damping rod 3 at the bottom to retract into the damper 2 hidden at the bottom of the base 1, triggering the damping effect in the vertical direction. The vibration force can be buffered and absorbed by the damper 2 and the buffer spring 4.

[0017] Please see Figures 1-4An engine-connected shock absorber foot has a connecting plate 7 on the top of a slider 6. A sleeve rod 8 is provided on the inner wall of the connecting plate 7, and a telescopic rod 9 is installed on the inner wall of the sleeve rod 8. A pressure plate 10 is fixedly connected to the top of the telescopic rod 9. The pressure plate 10 forms a telescopic structure with the sleeve rod 8 via the telescopic rod 9, and the telescopic rod 9 is inserted into the sleeve rod 8. The surface of the pressure plate 10 has an anti-slip texture, and the pressure plate 10 is movably connected to the connecting plate 7. When using the device, pulling the handle or edge of the pressure plate 10 upwards causes the pressure plate 10 to move the telescopic rod 9 connected at the bottom upwards simultaneously. The telescopic rod 9 extends upwards along the inner wall of the sleeve rod 8 until the distance between the pressure plate 10 and the connecting plate 7 is greater than the thickness of the engine connection point. Then, the connecting plate 7 is placed on the engine. Below the connection point, manually push the pressure plate 10 downwards. After the pressure plate 10 is under force, it drives the telescopic rod 9 to retract into the sleeve rod 8 until the bottom of the pressure plate 10 is completely in contact with the top surface of the engine connection point. At this time, the top of the connecting plate 7 is also tightly in contact with the bottom of the engine connection point, forming an upper and lower clamping state. Then, use bolts to fix the engine connection point, pressure plate 10 and connecting plate 7. Using pressure plate 10 and connecting plate 7 to clamp the engine connection point can improve the connection rigidity, while accurately suppressing the vibration and displacement of the engine in the vertical direction, improving the stability of the connection, and at the same time not affecting the normal thermal expansion and contraction displacement of the engine. Then, by adjusting the extension and retraction of the sleeve rod 8 and telescopic rod 9, it can adapt to engine connection points of different thicknesses.

[0018] Working principle: In use, first move the device to the appropriate position, then pull the pressure plate 10 upwards. The pressure plate 10 is stressed and moves upwards, simultaneously driving the telescopic rod 9 upwards. Then, place the connecting plate 7 below the engine connection point. Next, push the pressure plate 10 downwards. The pressure plate 10 is stressed and moves downwards, simultaneously driving the telescopic rod 9 to move inwards into the sleeve rod 8 until the pressure plate 10 is in contact with the top of the engine connection point. Then, use bolts to fix the engine connection point, pressure plate 10, and connecting plate 7. The pressure plate 10 and connecting plate 7 clamp the engine connection point, which can improve the connection rigidity and precisely suppress engine... The downward vibration and displacement improve the stability of the connection. When the engine is vibrated, the vibration is transmitted to the connecting plate 7. The connecting plate 7 is subjected to force and then transmitted to the slider 6. The slider 6 is subjected to force and moves downward, driving the damping rod 3 below to move into the damper 2. At the same time, it squeezes the slider 6, driving the slider 6 to move towards the dampers 2 on both sides inside the base 1. This drives the damping rod 3 to move into the damper 2 and compresses the buffer spring 4. The vibration force can be buffered and absorbed by the damper 2 and the buffer spring 4. This completes the use of the device. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0019] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
