Description

Technical Field

[0001] This utility model relates to the field of extended suspension, specifically an extended suspension for automobile engines. Background Technology

[0002] The car suspension is a system that connects the car body to the wheels. Its main function is to buffer road impacts, suppress body vibrations, and ensure driving comfort and handling.

[0003] Chinese Patent No. CN202421123357.4 discloses an extended suspension for automobile engines, including an extended suspension body and a locking assembly fixedly installed between two extended suspension bodies. An engine is detachably installed within the locking assembly, and the fixing contact points between the locking assembly and the engine are triangularly distributed, thereby enabling triangular fixation of the engine. As a further embodiment of this invention, the locking assembly includes a square frame and triangular blocks. Two sets of triangular blocks are fixedly installed on the surface of the engine piston cover, and the two sets of triangular blocks are respectively fixedly installed on both sides within the square frame. The square frame is fixedly installed between the two extended suspension bodies.

[0004] As can be seen from the above, it is possible to avoid engine displacement or vibration caused by shock and sudden rotation. However, this case still has the following shortcomings:

[0005] Firstly, the suspension support range is fixed and cannot be flexibly expanded according to engine model, size, or operating conditions, resulting in poor adaptability.

[0006] Secondly, the buffer structure is simple, relying solely on spring damping. When facing complex road conditions, vibration transmission is obvious, affecting engine stability.

[0007] Third, the adjustment mechanism lacks precision, making it difficult to achieve accurate control of the support range and resulting in low installation and debugging efficiency.

[0008] Therefore, an extended suspension for automobile engines is proposed to address the above problems. Utility Model Content

[0009] To overcome the shortcomings of existing technologies, such as narrow suspension adaptability and poor cushioning effect, this utility model proposes an extended suspension for automobile engines.

[0010] The technical solution adopted by this utility model to solve its technical problem is as follows: An extended suspension for an automobile engine, comprising a transmission body, an extension adaptation device provided on one side of the transmission body, the extension adaptation device including an adjusting component and an extension component; the adjusting component includes a fixing frame, a servo motor fixedly mounted on one side of the fixing frame, a ball screw fixedly mounted on the output end of the servo motor, a ball nut threaded through and connected to the ball screw, a telescopic rubber sleeve sleeved on the outer surface of the ball screw, the telescopic rubber sleeve extending and retracting with the movement of the ball nut, a lifting plate fixedly mounted on one side of the ball nut, two connecting rods fixedly mounted on the back side of the lifting plate, two connecting rods respectively hinged to a linkage rod, and the other ends of the two linkage rods respectively hinged to a movable block.

[0011] Preferably, the adjusting component further includes two second slide rails, each with a second slider slidably mounted on its bottom, and each of the two second sliders having a movable block fixedly mounted on its bottom.

[0012] Preferably, two first slide rails are fixedly installed on one side of the fixed frame, and a first slider is slidably installed on one side of each of the two first slide rails. The other side of the two first sliders is fixedly installed on the back of the lifting plate.

[0013] Preferably, the extension includes a connecting frame, with lower triangular frames hinged to both sides of the connecting frame, and two buffers hinged to each of the two lower triangular frames.

[0014] Preferably, the extension further includes two connectors, each of which is movably mounted on one end of the lower tripod and each of which is movably mounted on an upper tripod. One side of each of the two upper tripods is hinged to the connecting frame.

[0015] Preferably, the four buffers are each hinged to two movable blocks.

[0016] Preferably, the outer surface of the transmission body is fixedly installed in the inner cavity of the connecting frame, and both ends of the transmission body are rotatably installed in the inner cavity of the connecting member.

[0017] Preferably, the buffer includes an inner rod, an outer cylinder, and a composite elastic element. The inner rod is slidably inserted into the inner cavity of the outer cylinder, and the composite elastic element is sleeved on the outside of the inner rod with its two ends abutting the top of the inner rod and the bottom of the outer cylinder, respectively. The composite elastic element is composed of alternating layers of rubber pads and metal springs to enhance the absorption capacity of multi-frequency vibrations.

[0018] The advantages of this utility model are:

[0019] 1. This utility model, through the structural design of the adjusting component, uses a servo motor to drive the ball screw to move the lifting plate precisely.

Through the structural design of the extension component, the buffer adopts a composite elastic component with alternating rubber pads and metal springs, which can absorb multi-frequency vibrations. Combined with the stable support of the triangular frame structure, it solves the problem of significant vibration transmission in a single buffer structure and improves the stability of the engine under complex road conditions.

[0028] 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 scope of protection of the present utility model.

[0029] Please see Figures 1-5 As shown, an extended suspension for an automobile engine includes a transmission body 1. An extended adaptation device 2 is provided on one side of the transmission body 1. The extended adaptation device 2 includes an adjusting component 3 and an extending component 4. The adjusting component 3 includes a fixing frame 21. A servo motor 22 is fixedly installed on one side of the fixing frame 21. A ball screw 23 is fixedly installed at the output end of the servo motor 22. A ball nut 24 is threaded through and connected to the ball screw 23. A telescopic rubber sleeve 25 is sleeved on the outer surface of the ball screw 23. The telescopic rubber sleeve 25 extends and retracts with the movement of the ball nut 24. A lifting plate 26 is fixedly installed on one side of the ball nut 24. Two connecting rods 29 are fixedly installed on the back side of the lifting plate 26. The two connecting rods 29 are respectively hinged to a linkage rod 31. The other ends of the two linkage rods 31 are respectively hinged to a movable block 32.

[0030] During operation, the servo motor 22 is started according to the engine size requirements. Its output end drives the ball screw 23 to rotate, and the ball nut 24 moves along the axial direction of the ball screw 23, which drives the lifting plate 26 to move synchronously. The telescopic rubber sleeve 25 extends and retracts with the ball nut 24, which can prevent dust and impurities from entering the ball screw 23 and affecting the accuracy. When the lifting plate 26 moves, it pushes the linkage rod 31 through the connecting rod 29, causing the movable block 32 to be displaced, providing power for the expansion of the support range.

[0031] Furthermore, the adjusting component 3 also includes two second slide rails 34, and a second slider 33 is slidably mounted on the bottom of each of the two second slide rails 34. A movable block 32 is fixedly mounted on the bottom of each of the two second sliders 33.

[0032] During operation, when the movable block 32 moves, the second slider 33 slides along the second slide rail 34 to provide low-friction guidance for the movable block 32, ensuring its smooth movement and avoiding the impact of shaking on the adjustment accuracy of the support range.

[0033] Furthermore, two first slide rails 27 are fixedly installed on one side of the fixed frame 21, and first sliders 28 are slidably installed on one side of each of the two first slide rails 27. The other side of the two first sliders 28 is fixedly installed on the back of the lifting plate 26.

[0034] During operation, as the lifting plate 26 moves, the first slider 28 slides synchronously along the first slide rail 27, limiting the movement trajectory of the lifting plate 26, preventing it from tilting, and ensuring the stability of power transmission.

[0035] Furthermore, the extension 4 includes a connecting frame 41, with a lower triangular frame 42 hinged to both sides of the connecting frame 41, and two buffers 45 hinged to each of the two lower triangular frames 42.

[0036] During operation, the lower triangular frame 42 can rotate around the connecting frame 41, and adjust the opening angle in conjunction with the thrust of the movable block 32, thereby changing the support range of the suspension. The buffer 45 connects the lower triangular frame 42 and the movable block 32, and can buffer the instantaneous impact force when the support range is adjusted, while absorbing vibration during driving.

[0037] Furthermore, the extension component 4 also includes two connectors 43, which are movably installed on one end of the lower tripod 42, and the upper tripod 44 is movably installed on the two connectors 43. One side of each of the two upper tripods 44 is hinged to the connecting frame 41.

[0038] During operation, the movable block 32 moves to push the lower triangular frame 42 and the upper triangular frame 44 to open or retract synchronously. The triangular frame structure distributes and transmits force through the connector 43, improving the overall support strength and ensuring the stability of the engine after installation.

[0039] Furthermore, four buffers 45 are respectively hinged to two movable blocks 32;

[0040] During operation, multiple buffers are evenly distributed at 45 degrees, which can absorb vibrations from multiple angles and avoid excessive force on a single buffer point, which would reduce the shock absorption effect.

[0041] Furthermore, the outer surface of the transmission body 1 is fixedly installed in the inner cavity of the connecting frame 41, and both ends of the transmission body 1 are rotatably installed in the inner cavity of the connecting piece 43.

[0042] During operation, the transmission body 1 is rigidly connected to the extended adaptation device 2 through the connecting frame 41 and the connecting piece 43 to ensure the stability of the power transmission path. At the same time, the rotational installation characteristics of the connecting piece 43 can adapt to the small displacements when the engine is working.

[0043] Furthermore, the buffer 45 includes an inner rod, an outer cylinder, and a composite elastic element. The inner rod is slidably inserted into the inner cavity of the outer cylinder, and the composite elastic element is sleeved on the outside of the inner rod with its two ends abutting the top of the inner rod and the bottom of the outer cylinder, respectively. The composite elastic element is composed of rubber pads and metal springs stacked alternately to improve the absorption capacity of multi-frequency vibrations.

[0044] When the engine vibrates, the inner rod slides along the outer cylinder, compressing the composite elastic component: the metal spring can absorb low-frequency large-amplitude vibrations, and the rubber pad can absorb high-frequency small-amplitude vibrations. The two are superimposed alternately to achieve efficient filtering of multi-frequency vibrations and reduce the transmission of vibrations to the vehicle body.

[0045] Working principle: During use, the support range is adjusted according to the engine model: the servo motor 22 drives the ball screw 23 to move the lifting plate 26, which pushes the movable block 32 through the connecting rod 29 and the linkage rod 31, so that the lower triangular frame 42 and the upper triangular frame 44 open to the appropriate angle; the engine is fixed to the connecting frame 41 and the connecting piece 43 through the transmission body 1. During the driving process, the composite elastic element of the buffer 45 absorbs multi-frequency vibration, disperses the support force, and ensures stable engine operation.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
