Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile front axle travel, in particular to a quickly disconnectable connecting rod. Background Art
[0002] The small link is typically installed in the suspension system of off-road vehicles, specifically at the point where the stabilizer bar connects to the front axle. This design allows the small link to be disconnected as needed during off-road driving, increasing the travel of the front axle and improving the vehicle's maneuverability and stability.
[0003] In the prior art, the small link needs to be installed on the balance bar and the front axle before use, so that additional front axle travel can be obtained during off-road travel. When the car has no off-road requirements, the small link is removed to restore the suspension system to its original state. The installation and removal of the small link requires professional skills and tools, and usually requires experienced technicians to operate, and the removal process may require the disassembly of other components, which increases the complexity and time-consuming nature of the operation. Frequent installation and removal operations may cause damage to components and increased wear, thereby increasing maintenance costs. After the small link is removed, the state of the suspension system will change, which may cause the vehicle to become unstable during driving. This instability may manifest as vehicle deviation, shaking, etc., affecting driving safety and comfort. Utility Model Content

[0007] Preferably, a connecting joint 1 and a connecting joint 2 are respectively provided at both ends of the outer surface of the connecting rod tube, and the connecting joint 1 and the connecting joint 2 are respectively connected to the balance bar and the front axle of the automobile.
[0008] Preferably, the locking assembly includes a support sleeve, the support sleeve is fixedly arranged on the end of the connecting rod tube, and a support block is provided on the support sleeve.
[0009] Preferably, a fixing sleeve is fixedly provided on the support block, an elastic member 1 is provided inside the fixing sleeve, a knob is slidably provided on the outer surface of the fixing sleeve, a pressing rod is fixedly provided inside the knob, and protrusions are symmetrically provided on the pressing rod.
[0010] Preferably, the pressing rod passes through the fixing sleeve, the connecting sleeve, the supporting block and the supporting sleeve in sequence, and the elastic member is provided on the outer surface of the pressing rod and is located between the knob and the fixing sleeve.
[0011] Preferably, the locking mechanism further comprises a limiting tube, which is fixedly arranged on the inner wall of the connecting rod tube, and the limiting grooves are symmetrically arranged through the limiting tube, and the groove walls of the limiting grooves are slidably connected to the protrusions.

Simply turning the knob quickly releases the squeezing force of the elastic element, freeing the ball bearing from restricting the engaging block, thereby unlocking the travel lever. This design simplifies the operation process and increases flexibility and convenience.
[0018] By leveraging elastic elements 1, 2, and 3 in conjunction with the ball bearings to create a two-way compression limiter, the travel lever in the small connecting rod is locked. This locking reduces wobbling during off-road driving, making the suspension system more stable. This helps improve vehicle handling and driving safety. To release the travel lever, turn the knob again. This releases the compressive force from elastic elements 1, 2, and 3, causing the ball bearings to release their restraints on the latching block, unlocking the travel lever. This unlocked travel lever allows the suspension system to adjust more flexibly to varying road conditions, adapting to varying driving needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention is described in further detail below with reference to the accompanying drawings.
[0027] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.
[0028] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate directions or positions are based on the directions or positional relationships shown in the accompanying drawings, which are merely simplified descriptions for the convenience of describing the present invention, and do not indicate or imply that the device or component referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, the above terms should not be understood as limitations on the present invention.
[0029] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity. Example
[0030] See also Figure 1-Figure 5 , which can quickly disconnect the connecting rod, includes: a connecting rod cylinder 1, a travel rod 2 is provided on the inner wall of the connecting rod cylinder 1, a clamping block 201 is provided on the end of the travel rod 2, and the travel rod 2 slides on the inner wall of the connecting rod cylinder 1 through the clamping block 201; a locking assembly is provided on the connecting rod cylinder 1, and the locking assembly is adapted to the clamping block 201 and controls the stroke release of the travel rod 2. When the connecting rod is in a connected state, the locking assembly will lock the clamping block 201, thereby fixing the position of the travel rod 2 and ensuring the stability and connectivity of the connecting rod. When the connecting rod needs to be disconnected, the locking assembly can be unlocked to release the lock on the clamping block 201. Once the locking assembly is unlocked, the travel rod 2 can slide freely in the connecting rod cylinder 1, thereby realizing the quick disconnection of the connecting rod.
[0031] The connecting rod tube 1 has two ends on its outer surface, one connecting joint 3 and the other connecting joint 4. These two joints are connected to the vehicle's stabilizer bar and front axle, respectively. The primary function of the first connecting joint 3 is to connect the connecting rod to the vehicle's stabilizer bar. The stabilizer bar is a crucial component in the vehicle's suspension system, helping to reduce body roll during cornering or on uneven roads, thereby improving vehicle stability and handling. Through the first connecting joint 3, the connecting rod transmits the motion of the stabilizer bar to the front axle or other related components, thereby achieving coordinated movement of the suspension system. The primary function of the second connecting joint 4 is to connect the connecting rod to the vehicle's front axle. The front axle is a crucial component of a vehicle, supporting the front weight and guiding the vehicle's forward direction. Through the second connecting joint 4, the connecting rod transmits motion from the stabilizer bar or other suspension components to the front axle, thereby achieving coordination between the vehicle's suspension and steering movements.
[0032] Furthermore, the locking assembly includes a support sleeve 5, which serves as the basic support structure for the locking assembly and ensures that other components can be stably installed and positioned. The support sleeve 5 is fixedly mounted at the end of the connecting rod tube 1. A support block 6 is provided on the support sleeve 5 to provide additional support and positioning points, ensuring that the locking assembly can accurately mate with the connecting rod tube 1 and the clamping block 201 of the travel rod 2. A fixed sleeve 8 is fixedly mounted on the support block 6, serving as a mounting base for the elastic member 9 and the knob 10, while also providing a sliding track for the knob 10 to slide. The elastic member 9 is disposed within the fixed sleeve 8, and the knob 10 is slidably mounted on the outer surface of the fixed sleeve 8. As the user-operated component, it controls the locking and unlocking of the locking assembly by rotating and sliding. A pressing rod 11 is fixedly mounted within the knob 10. When the knob 10 is operated, the pressing rod 11 moves accordingly and cooperates with the clamping block 201 to achieve the locking and unlocking functions. The pressing rod 11 is symmetrically provided with protrusions 12. When the pressing rod 11 moves, the protrusion 12 moves synchronously.
[0033] The pressing rod 11 sequentially extends through the fixing sleeve 8, the connecting sleeve, the support block 6, and the support sleeve 5. The elastic member 1-9 is mounted on the outer surface of the pressing rod 11 and is located between the knob 10 and the fixing sleeve 8. The primary function of the elastic member 1-9 is to provide a spring force, ensuring that the pressing rod 11 remains in its initial position when not in use. When the knob 10 is operated, it compresses the elastic member 1-9, causing the pressing rod 11 to move and engage the engaging block 201. Once the knob 10 is released, the elastic force of the elastic member 1-9 pushes the pressing rod 11 and the knob 10 back into place.
[0034] Furthermore, the locking mechanism also includes a limit tube 13, which is fixedly arranged on the inner wall of the connecting rod tube 1, and a limit groove 14 is symmetrically arranged on the limit tube 13, and the groove wall of the limit groove 14 is slidably connected to the protrusion 12. A fixed tube 15 is slidably arranged on the inner wall of the limit tube 13, and an elastic member 2 16 is sleeved on the outer surface of the fixed tube 15, and the elastic member 2 16 is located between the fixed tube 15 and the limit tube 13. A through groove 17 is symmetrically arranged on the outer surface of the fixed tube 15, and the through groove 17 is bent vertically, and the groove wall of the through groove 17 is slidably connected to the protrusion 12. A sliding tube 18 is slidably arranged on the inner wall of the fixed tube 15, and an elastic member 3 19 is fixedly arranged at the groove bottom of the sliding tube 18 and the recess at the bottom of the pressing rod 11. A ball 20 is rollingly arranged on the side of the fixed tube 15 close to the clamping block 201. When the vehicle stops, by pressing the knob 10 downward, the knob 10 causes the elastic member 1 9 to be compressed, and at the same time, the pressing rod 11 squeezes the sliding tube 18 to cause the elastic member 2 16 and the elastic member 3 19 to be compressed, and the protrusion 12 moves synchronously with the pressing rod 11. At this time, rotating the knob 10 causes the protrusion 12 to be stuck in the horizontal section of the through groove 17 and limit it. At the same time, the clamping block 201 at the top of the travel rod 2 is limited and locked by the ball 20 on the sliding tube 18. When the travel needs to be released, the knob 10 is rotated again, causing the elastic member 1 9, the elastic member 2 16, and the elastic member 3 19 to lose the squeezing force, and then the ball 20 loses the limit on the clamping block 201, and the travel rod 2 is unlocked. The user can use the unlocked state of the travel rod 2 for off-road driving.
[0035] It should be added that, by means of the two-way extrusion limit of elastic member 1 9, elastic member 2 16 and elastic member 3 19 in conjunction with the ball 20, the travel rod 2 in the small connecting rod is locked. The locking of the travel rod 2 reduces its shaking during off-road driving, making the suspension system more stable. This helps to improve the vehicle's handling and driving safety. When the travel needs to be released, the knob 10 is rotated again, and the extrusion force of elastic member 1 9, elastic member 2 16 and elastic member 3 19 is released, causing the ball 20 to lose its restriction on the clamping block 201, and the travel rod 2 is unlocked. The unlocked travel rod 2 allows the suspension system to be more flexibly adjusted according to road conditions, thereby adapting to different driving needs. With the simple operation of the knob 10, the extrusion force of the elastic member can be quickly released, so that the ball 20 no longer restricts the clamping block 201, thereby achieving the unlocking of the travel rod 2. This design simplifies the operation process and improves the flexibility and convenience of operation. At the same time, it avoids damage to components and increased wear caused by frequent disassembly of the small connecting rod.
