Description

Technical Field

[0001] The invention relates to the technical field of suspension systems, in particular to an automobile suspension spring that is easy to connect. Background Art

[0002] The automobile suspension system is a key component of the automobile, which directly affects the driving comfort, handling stability and safety of the automobile. With the continuous development of the modern automobile industry, air springs, as an important elastic element in the suspension system, are widely used in various mid-to-high-end automobiles due to their adjustability and good shock absorption performance.

[0003] Traditional automobile air springs often lack versatility when connected to air pipes. Since the diameters of air pipes may vary between different models or different configurations of the same model, the connection structure of the air spring is difficult to adapt to air pipes of various diameters. This results in the need to equip air springs of different types for air pipes of different diameters during automobile production, or to use complex adapters to achieve connection, which increases the complexity and cost of production. In addition, due to various posture changes and vibrations during the driving of the car, the air pipe may bend or even fold. In particular, when the vehicle frequently goes up and down hills, over speed bumps, etc., the air pipe is stretched and squeezed more significantly. Once the air pipe is folded, it will seriously hinder the normal circulation of gas, making the air spring unable to work properly, causing the suspension system to fail and affecting the driving of the car.

[0014] Preferably, the pawl is engaged with the ratchet teeth.

[0015] Working principle: Automobile suspension spring is composed of air bladder, waist ring, aluminum alloy flange, upper cover plate and connecting pipe, etc. The air bladder is the core, the waist ring enhances its structural stability, the aluminum alloy flange is used to connect automobile related parts, and the upper cover plate realizes the connection between the air bladder and the outside through the connecting pipe. One end of the connecting pipe is connected to the air bladder, and the other end is provided with an adapter connection mechanism for connecting the air pipe. Its outer wall is provided with a sorting and storage mechanism, and there is also a positioning component outside the adapter connection mechanism to improve the connectivity. The adapter ring in the adapter connection mechanism is connected to the inside of the connecting pipe. When the air pipe is inserted, the air pipe enters the adapter ring. The positioning shaft on the fixed ring inside the connecting pipe is connected to the positioning plate. The force of the air pipe insertion will cause the positioning plate to rotate around the positioning shaft. The short rod on the positioning plate rotates, driving the arc ring to squeeze and fix the air pipe, so that air pipes of different diameters can be initially fixed in the adapter ring. When the positioning plate rotates, the L-shaped rod in the empty groove of its outer wall will slide accordingly. One end of the L-shaped rod slides in the empty groove, and the convex ring connected to the other end rotates in the connecting tube. The rotation of the convex ring can adjust the internal space structure of the connecting tube to better adapt to the trachea connection, while ensuring the stability of the trachea in the connecting tube and the smooth flow of gas. The swivel in the positioning assembly is slidably connected to the outer wall of the convex ring. In the initial state, the swivel and the convex ring are in the same vertical position. One end of the spring on one side of the outer wall of the swivel is connected to the swivel, and the other end is connected to the outer wall of the connecting tube. The other side of the outer wall of the swivel is connected to the pawl through a long rod. The outer wall of the connecting tube is fixed with ratchet teeth, and the ratchet teeth are meshed with the ratchet teeth. When the trachea is inserted and the adaptation connection is completed, the spring is in a normal state, the swivel position is stable, and the meshing of the pawl and the ratchet teeth can prevent the swivel from moving in the opposite direction, thereby further improving the connection stability between the trachea and the adaptation connection mechanism. The long plate on the swivel is connected to the pawl through a tension spring to prevent excessive relative displacement between the pawl and the ratchet, ensure the normal operation of the positioning assembly, maintain the stability of the air pipe connection, ensure the normal operation of the vehicle suspension spring and the reliable transmission of gas. When the air pipe needs to be replaced, push the swivel to contract the spring, and the movement of the swivel drives the pawl and ratchet to disengage. At this time, the arc ring outside the air pipe no longer exerts extrusion force on the air pipe, and the air pipe can be smoothly pulled out of the adapter connection mechanism to complete the replacement operation. The extension tube in the organizing and storing mechanism is connected to one end of the connecting tube, and the bent plate on one side of the outer wall of the extension tube and the extension tube form a storage compartment, in which the wire harness tube is placed. When the adapter connecting mechanism is connected to the air pipe, the wire harness tube can be taken out of the storage compartment and slid to the outside of the air pipe. The wire harness tube can protect the air pipe and prevent it from being entangled and worn due to vehicle vibration or other factors. The pipe clamp at one end of the outer wall of the wire harness tube can be used to position the air pipe. Placing the pipe clamp in a suitable position can tightly clamp the air pipe and the wire harness tube, so that the air pipe remains stable in a specific position and displacement is avoided during vehicle driving, thereby improving the stability and safety of the air pipe connection. At the same time, the internal wiring of the car is made neater and more beautiful, which is convenient for subsequent maintenance and inspection.There is a partition plate inside the containing plate on one side of the outer wall of the wiring harness tube. When the trachea is bent at a large angle, the anti-folding plate rotates under the action of the compression spring to further support one side of the outer wall of the trachea. The anti-folding plate can be adaptively adjusted according to the bending direction of the trachea, and together with the extension plate, it provides stable support for the trachea to avoid folding of the trachea and ensure that the airflow effect is not affected.

[0016] The present invention provides an automobile suspension spring that is easy to connect and has the following beneficial effects:

[0017] 1. The present invention uses an adaptable connection mechanism so that the suspension air spring can adapt to air pipes of different diameters. During automobile production or maintenance, no matter what specifications of the air pipe, it can be quickly and accurately connected to the suspension spring. It is no longer necessary to specially equip multiple types of suspension springs or complex adapters for different air pipe diameters, which greatly improves installation efficiency and reduces installation time delays caused by adaptation problems.

[0018] 2. The present invention provides great convenience for the management of the air pipe through the storage mechanism. The wire harness in the storage bin can be easily taken out and the air pipe can be protected and arranged, so that the air pipe is neat and orderly in the interior space of the car. The pipe clamp can firmly fix the air pipe in a specific position to prevent the air pipe from being entangled with each other or damaged by friction with other parts due to the shaking of the vehicle during driving. This not only prolongs the service life of the air pipe, but also facilitates the inspection and maintenance of the air pipe in the later stage.

[0019] 3. The anti-folding mechanism of the air pipe on the wiring harness of the present invention plays an important role. When the air pipe is bent due to gravity or other factors, the accommodating plate, lightweight spring, extension plate, anti-folding plate, compression spring and other components work together to effectively prevent the air pipe from being excessively folded, thereby ensuring the normal circulation of gas in the air pipe and maintaining the normal performance of the vehicle suspension system.

[0031] The adapting connection mechanism includes an adapting ring 6, which is connected to the interior of the connecting tube 5, and a fixing ring 7 is fixedly connected to the interior of the connecting tube 5, and one end of a positioning shaft 8 is fixedly connected to one side of the outer wall of the fixing ring 7, and the other end of the positioning shaft 8 is rotatably connected to a positioning plate 9, and a short rod 10 is fixedly connected to one side of the outer wall of the positioning plate 9, and one end of the short rod 10 is rotatably connected to an arc ring 11, and an empty groove 12 is opened on one side of the outer wall of the positioning plate 9, and one end of an L-shaped rod 13 is slidably connected to the interior of the empty groove 12, and the other end of the L-shaped rod 13 is fixedly connected to a convex ring 14, and the convex ring 14 is rotatably connected to the interior of the connecting tube 5;

[0032] The positioning assembly includes a swivel 20, which is slidably connected to the outer wall of the convex ring 14, one end of a spring 1 is fixedly connected to one side of the outer wall of the swivel 20, and the other end of the spring 1 is fixedly connected to one side of the outer wall of the connecting tube 15, one end of a long rod 22 is fixedly connected to the other side of the outer wall of the swivel 20, and the other end of the long rod 22 is rotatably connected to a pawl 23, and the outer wall of the connecting tube 15 is fixedly connected to a ratchet 24, one side of the outer wall of the swivel 20 is fixedly connected to a long plate 25, one side of the outer wall of the long plate 25 is connected to one end of a tension spring 26, and the other end of the tension spring 26 is fixedly connected to one side of the outer wall of the pawl 23;

[0033] The outer wall of the rotating ring 20 is provided with evenly distributed annular recesses 38, and a rubber pad 39 is fixedly connected inside the annular recesses 38;

[0034] Specifically, the air bag body 1 is used as a core component, and the waist ring 2 is used to enhance the structural stability. The aluminum alloy flange 3 is used to connect the automobile parts. The connecting pipe 5 connected to the upper cover plate 4 is connected to the outside. In the adapter connection mechanism, the adapter ring 6 is connected to the connecting pipe 5 to adapt to air pipes of different diameters. When the air pipe is inserted, the positioning plate 9 is pushed to rotate around the positioning shaft 8. The short rod 10 drives the arc ring 11 to squeeze and fix the air pipe. When the positioning plate 9 rotates, the L-shaped rod 13 slides in the empty groove 12 and drives the convex ring 14 to rotate. The groove 29 in the empty groove 12 and the roller 30 at one end of the L-shaped rod 13 make the sliding smoother. The convex ring 14 rotates to adjust the internal space structure of the connecting pipe 5. The positioning component further improves the connection stability on the basis of the adapter connection. In the initial state, the swivel 20 is in the same vertical position as the convex ring 14, the pawl 23 is engaged with the ratchet 24 on the outer wall of the connecting tube 5 to prevent the swivel 20 from moving in the opposite direction, and the long plate 25 cooperates with the pawl 23 through the tension spring 26 and the telescopic rod 28. The tension spring 26 provides tension to make the pawl 23 tightly clamp the ratchet 24, and the telescopic rod 28 guides, supports and limits the movement range of the pawl 23, ensuring the normal operation of the positioning component, maintaining the connection stability, and ensuring the normal operation of the automobile suspension spring and the reliability of gas transmission. When the air pipe needs to be replaced, the swivel 20 is pushed to force the spring 21 to contract. At this time, the pawl 23 is disengaged from the ratchet 24, and the arc ring 11 outside the air pipe no longer exerts a squeezing force on it, so that the air pipe can be replaced.

[0035] The storage mechanism includes an extension tube 15, which is connected to one end of the connecting tube 15, and a bent plate 16 is fixedly connected to one side of the outer wall of the extension tube 15. The bent plate 16 and the extension tube 15 form a storage bin 17, and a wire harness tube 18 is placed inside the storage bin 17. A tube clamp 19 is fixedly connected to one end of the outer wall of the wire harness tube 18.

[0036] Specifically, after the adapter connection mechanism is connected to the external air pipe, the sorting and storage mechanism begins to work, and the extension tube 15 is connected to one end of the connecting tube 15, providing a basic connection for the subsequent sorting and storage operations. A bent plate 16 is fixedly connected to one side of the outer wall of the extension tube 15, and the bent plate 16 and the extension tube 15 together constitute a storage bin 17, in which a wire harness tube 18 is placed, and the wire harness tube 18 can be flexibly operated according to actual needs. When it is necessary to sort the connected air pipe, the wire harness tube 18 can be taken out of the storage bin 17 and slid to the outside of the air pipe. The wire harness tube 18 can protect and sort the air pipe, so that it can be arranged more neatly and orderly in the interior space of the car, and avoid the air pipe from being entangled, worn, etc. due to vibration or other factors during the driving of the vehicle. A pipe clamp 19 is fixedly connected to one end of the outer wall of the wire harness tube 18. By placing the pipe clamp 19, the air pipe can be quickly positioned at various positions. The pipe clamp 19 can tightly clamp the air pipe and the harness pipe 18, ensuring the stability of the air pipe in a specific position and preventing it from shifting during the driving of the vehicle. In this way, the stability and safety of the air pipe connection are improved, and the wiring inside the car is made neater and more beautiful, which is convenient for subsequent maintenance and inspection.

[0037] A short shaft 27 is fixedly connected to one side of the outer wall of the long plate 25 and the pawl 23. The two short shafts 27 are internally rotatably connected to a telescopic rod 28, and the telescopic rod 28 passes through the tension spring 26;

[0038] The pawl 23 is meshed with the ratchet teeth 24;

[0039] Specifically, the telescopic rod 28 serves as a support inside the tension spring 26 to prevent the tension spring 26 from lateral twisting and deformation, which would reduce its service life. At the same time, the predetermined length of the telescopic rod 28 limits the telescopic length of the tension spring 26 to avoid excessive relative displacement between the pawl 23 and the ratchet tooth 24.

[0040] A groove 29 is formed inside the empty slot 12, and a roller 30 is rotatably connected to one end of the L-shaped rod 13, and the roller 30 is slidably connected inside the groove 29;

[0041] Specifically, the roller 30 converts the sliding motion of one end of the L-shaped rod 13 in the empty groove 12 into a rolling motion, which reduces the generation of friction to a certain extent and makes the movement of the L-shaped rod 13 smoother.

[0042] A receiving plate 31 is fixedly connected to one side of the outer wall of the wiring harness tube 18, a partition plate 32 is fixedly connected to the inside of the receiving plate 31, one end of a lightweight spring 33 is fixedly connected to the outer wall of the partition plate 32, and an extension plate 34 is fixedly connected to the other end of the lightweight spring 33, and the extension plate 34 is slidably connected to the inside of the partition plate 32.

[0043] A rotating shaft 35 is fixedly connected to one side of the outer wall of the extension plate 34, and an anti-folding plate 36 is rotatably connected inside the rotating shaft 35. One end of a compression spring 37 is fixedly connected to one side of the outer wall of the anti-folding plate 36, and the other end of the compression spring 37 is fixedly connected to the outer wall of the extension plate 34;

[0044] Specifically, after the cable harness tube 18 clamps the trachea, the cable harness tube 18 is positioned by the tube clamp 19. However, in actual use, the trachea may deviate from the parallel position with the cable harness tube 18 due to factors such as gravity. At this time, the trachea at both ends of the cable harness tube 18 are prone to bending. A receiving plate 31 is fixedly connected to one side of the outer wall of the cable harness tube 18. A partition plate 32 is fixedly connected to the inside of the receiving plate 31, and the partition plate 32 plays a supporting and partitioning role. One end of a light spring 33 is fixedly connected to the outer wall of the partition plate 32, and an extension plate 34 is fixedly connected to the other end of the light spring 33. The extension plate 34 is slidably connected to the inside of the partition plate 32. When the trachea is bent, the extension plate 34 will slide outward under the action of the light spring 33. When the trachea is bent in a certain direction, the anti-folding plate 36 will rotate to a suitable angle under the push of the compression spring 37, and provide stable support for the trachea together with the extension plate 34, so as to avoid the folding of the trachea and reduce the air flow effect.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
