Description

Technical Field

[0001] This invention relates to the field of parts packaging technology, and in particular to a multi-layer packaging structure for automotive steering knuckles. Background Technology

[0002] The steering knuckle is a core load-bearing component of the automotive steering system, essentially a joint connecting the wheels and the vehicle body, and its role is crucial. One end is connected to the front axle via a kingpin, while the other end is assembled with components such as the wheel hub and brakes. When the driver operates the steering wheel, it transmits steering force to the wheels, causing wheel deflection and thus controlling the vehicle's direction. Simultaneously, the steering knuckle must withstand various complex stresses during vehicle operation, including vertical loads, lateral forces, and braking forces. Its structural strength and precision directly affect the vehicle's handling stability and driving safety.

[0003] Throughout the entire process from production to final assembly into the vehicle, the steering knuckle undergoes multiple handling, transportation, and storage operations. Without effective packaging, it is highly susceptible to damage from collisions, friction, and compression, such as broken connecting lugs, scratches on contact surfaces, and deformation of the kingpin bore. This damage not only affects the assembly precision and lifespan of the steering knuckle but also poses a significant threat to vehicle safety. Furthermore, if the metal surface of the steering knuckle comes into contact with moisture and dust during storage or transportation, it may corrode, leading to performance degradation. Therefore, proper packaging provides precise fixation, cushioning, and protection for the steering knuckle, ensuring it maintains its original precision and quality during transit and reducing unnecessary losses and safety hazards.

[0004] Traditional automotive steering knuckle packaging often relies on foam filling or simple baffles for securing the multiple connecting lugs and contact surfaces of the steering knuckle. Foam filling, due to the limited resilience of the foam material, causes the filling gaps to gradually increase during repeated handling, leading to displacement of the steering knuckle within the packaging chamber. Furthermore, during road transport, longitudinal and lateral impacts from vehicle starting, braking, and uneven road surfaces can cause periodic shaking of the steering knuckle within the packaging. Simple baffles can only limit displacement in one direction; multi-directional combined vibrations can easily cause the steering knuckle to shake inside the packaging box. If the kingpin hole of the steering knuckle collides with adjacent components, it may cause dents in the hole wall, thus affecting product quality.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0006] This invention provides a multi-layered packaging structure for automotive steering knuckles, which solves the problem that traditional automotive steering knuckle packaging easily causes the steering knuckles to shake inside the packaging box during transportation, resulting in damage to the steering knuckles and affecting product quality.

The limiting component includes multiple dividing ramps installed inside the packaging box body. The dividing ramps divide the storage location into a first placement cavity and a second placement cavity. A second baffle is installed at the front end of the dividing ramps, and a first baffle is installed at the rear end of the dividing ramps. Multiple horizontal plates are provided in the middle of the packaging box body.

[0008] Furthermore, the first baffle is adapted to fit against the outer wall of the third contact surface on the vehicle steering knuckle body placed in the first placement cavity, and the second baffle is adapted to fit against the outer wall of the third contact surface on the vehicle steering knuckle body placed in the second placement cavity.

[0010] Furthermore, a first support plate is fixedly installed at the front end of each storage compartment inside the packaging box, and a second support plate is fixedly installed at the rear end of each storage compartment inside the packaging box. The first and second support plates can be used to support the first contact surface on the corresponding automotive steering knuckle body.

[0011] Furthermore, the bottom of the packaging box body is provided with multiple weight-reducing holes.

[0012] Furthermore, each of the horizontal plates is rotatably mounted on a corresponding dividing slope via a connecting shaft, and each dividing slope is provided with an adjustment component for adjusting the position of the horizontal plate, and a handle is fixedly installed at the upper end of the horizontal plate.

[0013] Furthermore, the adjustment assembly includes a cam fixedly mounted on the lower end of the connecting shaft on the horizontal plate. The cam has two symmetrical protrusions, and U-shaped frames are provided on both sides of the cam. Rollers are rotatably mounted on the lower ends of the two U-shaped frames that are close to the cam. The two rollers are in contact with the protrusions on the corresponding cams. The two U-shaped frames are slidably mounted on both sides of the dividing inclined plate through a guide mechanism. A limit rod is fixedly mounted on one side of the U-shaped frame, and a limit block is fixedly mounted on the outer wall of one end of the limit rod.

[0014] Furthermore, the guide mechanism is installed opposite to both ends of the partition inclined plate, and the guide mechanism includes two first guide plates fixedly installed on opposite sides of both ends of the partition inclined plate.

[0020] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0021] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] Reference Figures 1 to 13 As shown, this embodiment of the invention provides a multi-layer packaging structure for automotive steering knuckles, including multiple packaging box bodies 1, each of which can be stacked vertically. When stored in a warehouse, this structure can effectively reduce the floor space occupied, allowing more steering knuckles to be accommodated in limited storage space. During transportation, whether in a truck bed or a container, stacking can increase the loading capacity and reduce the unit transportation cost. Multiple storage compartments 11 are equidistantly arranged inside each packaging box body 1, ensuring that each steering knuckle has an independent placement space, avoiding mutual compression and collision, and facilitating batch loading and unloading by staff. At the same time, the equidistant design also helps to balance the stress on the internal structure of the packaging box body 1, improving the overall compressive strength. Each storage compartment 11 has a car steering knuckle body 4 on both sides inside, and the two steering knuckle bodies have complementary shapes. Since the structure of the car steering knuckle is relatively complex and has many concave and convex parts, the two car steering knuckle bodies 4 can be reasonably placed by the complementary shapes and the gap can be minimized, thereby saving placement space. Reference Figure 13 As shown, the lower part of one end of the car steering knuckle body 4 is the first contact surface 41, one side of the car steering knuckle body 4 has a first connecting ear 42, the other side of the car steering knuckle body 4 has a second connecting ear 44, the other side of the car steering knuckle body 4 is the second contact surface 43, the rear end of the car steering knuckle body 4 is provided with a third connecting ear 46, and the lower surface of the rear end of the car steering knuckle body 4 is the third contact surface 45. Reference Figure 5 As shown, the limiting component 2 inside each storage compartment 11, used to limit the movement of the vehicle steering knuckle body 4, is a core structure ensuring the stability of the vehicle steering knuckle body 4 during transportation. The limiting component 2 includes multiple dividing ramps 23 fixedly installed inside the packaging box body 1. The dividing ramps 23 divide the storage compartment 11 into a first placement cavity 21 and a second placement cavity 22. The shape and size of the two placement cavities are designed according to the shape of the vehicle steering knuckle body 4 and can be adapted to the vehicle steering knuckle body 4. The tilt angle of the dividing ramps 23 is adapted to the vehicle steering knuckle body 4, which can effectively separate the two steering knuckles without causing compression damage to the steering knuckles. A second baffle 210 is fixedly installed at the front end of the dividing ramp 23, which fits against the outer wall of the third contact surface 45 on the steering knuckle body 4 placed in the second placement cavity 22. A first baffle 29 is fixedly installed at the rear end, which fits against the outer wall of the third contact surface 45 on the steering knuckle body 4 placed in the first placement cavity 21. This design can limit the steering knuckle from the front and rear directions, preventing it from colliding with the packaging box due to back-and-forth swaying during transportation. The baffle is made of a material with a certain degree of elasticity, which can ensure sufficient support and also act as a buffer when subjected to external impact, reducing the impact force on the steering knuckle. Vertical plates 318 are provided on both sides of the dividing ramp 23 for limiting the steering knuckle body 4. The packaging box body 1 has multiple horizontal plates 24 in the middle, and the openings at the bottom of these plates are specifically designed for the third connecting lug 46 of the automotive steering knuckle body 4. When installing the automotive steering knuckle body 4, one end of the third connecting lug 46 is passed through the opening at the bottom of the corresponding horizontal plate 24, and the horizontal plate 24 can press the steering knuckle from above, forming a vertical limit.

[0023] This design prevents the steering knuckle body 4 from bouncing up during transportation due to external bumps, thus avoiding collisions between the steering knuckle and the top of the packaging box. The cross plate 24 is made of high-strength, hard material to ensure it can withstand the weight of the steering knuckle and the impact during transportation. At the same time, the edges of the opening are rounded to prevent scratches on the surface of the steering knuckle body 4.

[0024] Meanwhile, the front end of the packaging box body 1 is provided with multiple first inclined plates 25. Each first inclined plate 25 is located at the front end of the connecting plate between each storage compartment 11, and one side of the first inclined plate 25 is tightly fitted to the outer wall of the first connecting ear 42 on the corresponding car steering knuckle body 4. The tilt angle of the first inclined plate 25 is set according to the shape characteristics of the first connecting ear 42, which can apply a stabilizing force to the car steering knuckle body 4 from the side, further limiting its swaying in the left and right directions.

[0025] Since the first connecting lug 42 is a relatively prominent structure on the steering knuckle, it is easily displaced by external forces during transportation. The first inclined plate 25 is designed to specifically fix it, working in conjunction with other limiting structures to make the steering knuckle more secure. Moreover, the first inclined plate 25 is made of a wear-resistant and resilient material, which ensures the stability of its own structure without causing wear to the surface of the connecting lug when in long-term contact with the first connecting lug 42 or subjected to slight impacts. Multiple second inclined plates 26 are provided at the rear end inside the packaging box body 1. Each second inclined plate 26 is located at the rear end of the connecting plate between each storage compartment 11, and one side of the second inclined plate 26 is tightly fitted with the outer wall of the third connecting ear 46 on the corresponding car steering knuckle body 4, which can further limit the car steering knuckle body 4. The second inclined plate 26 is similar to the first inclined plate 25 and is also designed according to the structural characteristics of the third connecting ear 46. It forms a lateral constraint on the car steering knuckle body 4 from the rear end, and cooperates with the first inclined plate 25 at the front end to form a lateral limiting system that echoes each other.

[0026] As a crucial stress point at the rear end of the steering knuckle, the stability of the third connecting ear 46 directly affects the overall fixation of the steering knuckle. The second inclined plate 26, through a tight fit, effectively counteracts lateral impacts during transportation, preventing the steering knuckle from shifting or colliding due to lateral forces. Furthermore, the installation position of the second inclined plate 26 is calibrated to ensure optimal fit with the third connecting ear 46, avoiding both a loose fit that would compromise its limiting function and an overly tight fit that would cause deformation of the connecting ear. A first support plate 27 is fixedly installed at the front end of each storage compartment 11 inside the packaging box body 1, and a second support plate 28 is fixedly installed at the rear end of each storage compartment 11 inside the packaging box body 1. The first support plate 27 and the second support plate 28 can be used to support the first contact surface 41 on the corresponding automobile steering knuckle body 4, and can support the automobile steering knuckle body 4.

[0027] The first support plate 27 is located at the front end of the storage area 11 and supports the weight of the front part of the car steering knuckle body 4. The second support plate 28 is located at the rear end and bears the weight of the front end of another car steering knuckle body 4, forming a stable support system so that the steering knuckle remains horizontal during placement and avoids uneven stress on other limiting structures due to tilting. The bottom of the packaging box body 1 has multiple weight-reducing holes 5. These holes reduce material consumption, lower production costs, and also lessen the handling burden on workers, improving loading and unloading efficiency. Furthermore, the weight-reducing holes 5 enhance ventilation, facilitating air circulation within the box during storage and preventing damage to the steering knuckle caused by humidity or other environmental factors. The edges of the weight-reducing holes 5 are rounded to avoid sharp corners and prevent injury to workers or other items during handling.

[0028] Reference Figures 9 to 12 As shown, each horizontal plate 24 is rotatably mounted on its corresponding dividing plate 23 via a connecting shaft. During installation, workers can easily rotate the horizontal plate 24 to open it, eliminating the need to laboriously pass one end of the third connecting lug 46 on the steering knuckle body 4 through the opening at the bottom of the horizontal plate 24 as before. Instead, the steering knuckle body 4 can be placed vertically in the corresponding storage space 11. This eliminates the need for angle adjustment of the steering knuckle, which significantly reduces installation difficulty and time, especially for heavy and complex steering knuckles, and improves the convenience of storing the steering knuckle body 4. Each of the dividing ramps 23 is equipped with an adjustment component 3 for adjusting the position of the cross plate 24. This component allows the cross plate 24 to reset after the steering knuckle is placed and achieves more reliable positioning. The adjustment component 3 includes a cam 31 fixedly mounted on the lower end of the connecting shaft on the cross plate 24. The cam 31 has a symmetrical protrusion structure on both sides. The symmetrical design ensures that the force is evenly distributed during rotation, thereby achieving a stable adjustment effect. U-shaped brackets 32 are provided on both sides of the cam 31. Rollers 33 are rotatably mounted on the lower end of the two U-shaped brackets 32 on the side close to the cam 31. The two rollers 33 are in contact with the protruding surfaces on the corresponding cams 31.

[0029] When the horizontal plate 24 rotates, the connecting shaft drives the cam 31 to rotate synchronously. The convex surface of the cam 31 pushes the roller 33, which in turn drives the U-shaped frame 32 to slide on both sides of the dividing inclined plate 23 through the guide mechanism. A limit rod 34 is fixedly installed on one side of the U-shaped frame 32, and a limit block 38 is fixedly installed on the outer wall of one end of the limit rod 34. When the U-shaped frame 32 slides under the action of the cam 31 and the roller 33, the limit rod 34 will move accordingly.

[0030] When the horizontal plate 24 rotates to the closed position, one end of the limiting rod 34 precisely aligns with the through hole of the third connecting ear 46, and the limiting block 38 fits against the outer wall of the third connecting ear 46. This simultaneous limiting from both inside and outside the through hole of the connecting ear further enhances the limiting effect on the steering knuckle body 4, effectively preventing displacement of the steering knuckle due to severe bumps during transportation. The diameter of the limiting rod 34 matches the diameter of the through hole of the third connecting ear 46, ensuring smooth insertion while maintaining sufficient contact area for stable limiting force. The shape of the limiting block 38 adapts to the contour of the outer wall of the third connecting ear 46, ensuring a tight fit and preventing loosening.

[0031] Reference Figure 12 As shown, the guide mechanism is installed at both ends of the partition inclined plate 23, and the guide mechanism includes two first guide plates 35 fixedly installed on opposite sides of both ends of the partition inclined plate 23. The limiting rod 34 is slidably connected to the corresponding two first guide plates 35. The limiting rod 34 is fitted with a first spring 37 on the outer wall between the two first guide rods 311. A first retaining ring 36 is fixedly installed on the outer wall of the limiting rod 34 near the middle. One end of the spring is fixedly connected to the first retaining ring 36.

[0032] The first guide plate 35 provides a stable track for the sliding of the limiting rod 34, ensuring that the limiting rod 34 can only move in a specific direction and avoids deviation. The first spring 37 serves a reset function. When the cam 31 rotates, reducing the thrust on the roller 33, the first spring 37 will pull the limiting rod 34 back to its initial position through the first retaining ring 36. The guiding mechanism also includes a guide rod 311 fixedly installed on the other side of the U-shaped frame 32, and two second guide plates 312 fixedly installed on opposite sides of the dividing inclined plate 23. The guide rod 311 is slidably connected to the two corresponding second guide plates 312, and a second spring 313 is sleeved on the outer wall of the guide rod 311 between the two second guide rods 311. A second retaining ring 314 is fixedly installed on the outer wall of the guide rod 311 near the middle, and one end of the spring is fixedly connected to the second retaining ring 314. The second guide plates 312 provide support and guidance for the sliding of the guide rod 311, ensuring that the U-shaped frame 32 remains stable during movement. The second spring 313 cooperates with the second retaining ring 314, and when the thrust of the cam 31 disappears, it can drive the U-shaped frame 32 and the guide rod 311 to reset, so that the roller 33 always keeps in contact with the convex surface of the cam 31, ensuring the sensitivity and reliability of the adjusting component 3.

[0033] In addition, a handle 39 is fixedly installed on the upper end of the horizontal plate 24. The handle 39 is provided with anti-slip texture 310. The packaging box body 1 has slots 319 on both sides of the middle of each storage compartment 11. The horizontal plate 24 can be snapped into the slots 319. The lower end of each partition plate 23 is fixedly installed with an installation plate 315. The outer walls of both sides of the installation plate 315 are provided with hanging rings 316. The two sides of the horizontal plate 24 are provided with hooks 317. The hanging rings 316 can be fastened to the hooks 317 to fix and limit the horizontal plate 24. The fastening principle of the hanging rings 316 and the hooks 317 is a mature existing technology, so it will not be described in detail.

[0034] Working principle: In the initial state, the horizontal plate 24 is in an obliquely rotated open state. In this state, the horizontal plate 24 does not obstruct the entrance of the storage area 11, providing sufficient operating space for the insertion of the car steering knuckle body 4. At this time, the concave part of the cam 31 is in contact with the roller 33 on the U-shaped frame 32. Since the contour of the concave part of the cam 31 matches the roller 33, the two can make stable contact.

[0035] The spring is in its normal state, neither compressed nor stretched, maintaining its natural elasticity. Under the action of the spring force, the U-shaped bracket 32 ​​moves towards the center, thereby causing the limiting rod 34 to retract. One end of the limiting rod 34 is away from the through hole of the third connecting ear 46, so it will not obstruct the placement of the car steering knuckle body 4. This initial design allows workers to place the car steering knuckle body 4 without worrying about being interfered with by the limiting rod 34, and can easily and quickly place the steering knuckle vertically into the corresponding storage space 11, greatly improving placement efficiency. After the steering knuckle body 4 is stored, the staff rotates the handle 39 on the horizontal plate 24 to make the horizontal plate 24 rotate. As the horizontal plate 24 rotates, its two sides gradually engage with the corresponding slots 319. The inner wall of the slot 319 fits tightly with the two sides of the horizontal plate 24, providing effective support and fixation for the horizontal plate 24. This limits the upper and lower positions of the steering knuckle body 4 and prevents the steering knuckle from jumping up and down during transportation.

[0036] As the horizontal plate 24 rotates, the connecting shaft drives the cam 31 to rotate synchronously. The protrusions on both sides of the cam 31 gradually contact the rollers 33 on the U-shaped frame 32 and push the rollers 33, causing the two U-shaped frames 32 to move to both sides against the spring force. The movement of the U-shaped frames 32 causes the limiting rod 34 to extend to both sides synchronously, so that one end of the limiting rod 34 is precisely aligned with the through hole of the third connecting ear 46, further limiting the steering knuckle body 4 from the side, making the steering knuckle more secure.

[0037] After the limit is completed, the staff will then fasten the hanging rings 316 on both sides of the mounting plate 315 onto the corresponding hooks 317 on both sides of the horizontal plate 24. The hanging rings 316 and hooks 317 are tightly engaged, which can reliably lock the horizontal plate 24 and prevent the horizontal plate 24 from rotating accidentally during transportation, thereby completing the packaging and installation of the automobile steering knuckle body 4.
