Description

Technical Field

[0001] This utility model belongs to the field of automotive steering column technology, specifically an intelligent road-feeling automotive steering column with adaptive damping adjustment. Background Technology

[0002] With the increasing demand for intelligent vehicles and enhanced driving experiences, traditional fixed-damping steering columns can no longer meet the need for a dynamic balance between steering precision and comfort. Intelligent road-feel steering columns with adaptive damping adjustment are gradually becoming a core feature of mid-to-high-end models. Their core logic involves integrating sensing, control, and execution modules to respond in real-time to vehicle speed, road conditions, and driving operations, dynamically adjusting the steering damping force—for example, reducing damping at low speeds to lessen steering burden and increasing damping at high speeds to improve steering stability. Simultaneously, it filters out excessive vibrations from bumpy roads while retaining necessary road feel feedback, significantly optimizing driving safety and comfort.

[0003] Current mainstream adaptive damping steering columns typically consist of four core modules: a sensing layer (vehicle speed sensor, steering angle sensor, torque sensor, etc.) responsible for collecting vehicle dynamic data; a control layer (ECU electronic control unit) analyzing the data based on preset strategies and outputting adjustment commands; an execution layer (electromagnetic damper, electro-hydraulic control valve, etc.) receiving commands to change the damping force; and a mechanical layer (column body, universal joint) bearing the steering force transmission. However, with the increasing integration and enhanced functionality of these products, heat dissipation has gradually become a key bottleneck restricting their performance stability and lifespan.

[0004] Therefore, this utility model provides an intelligent road-feeling automotive steering column with adaptive damping adjustment. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve at least one of the problems mentioned in the background art, an intelligent road-feeling steering column with adaptive damping adjustment is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The intelligent road-feeling steering column with adaptive damping adjustment of this utility model includes a steering column; a fixed shell is rotatably mounted on the surface of the steering column, a rotating assembly is provided on the inner wall of the fixed shell, and a heat-conducting assembly is provided on the side of the steering column surface near the rotating assembly; a shock-absorbing mechanism is provided on the inner wall of the rotating shell, and a driving mechanism is provided on one side of the fixed shell; an auxiliary assembly is provided on the top of the inner wall of the rotating shell; the rotating assembly includes a rotating shell and a toothed ring, the rotating shell is rotatably mounted on the inner wall of the fixed shell, and the bottom of the rotating shell surface is fixedly mounted to the toothed ring; the cooperation between the rotating shell and the toothed ring enables rotation by the driving mechanism, which in turn drives the shock-absorbing mechanism to rotate, thereby allowing it to contact the heat-conducting sticker to conduct heat away.

[0007] Preferably, the heat-conducting component includes a heat-conducting plate and a heat-conducting sticker. Several sets of heat-conducting plates are provided, and the sets of heat-conducting plates are fixedly installed in a ring on the surface of the steering column near the rotating housing. The side of the heat-conducting plate away from the steering column is fixedly installed with the heat-conducting sticker. In this solution, the combined use of the heat-conducting plate and the heat-conducting sticker can conduct the heat of the steering column during use to the interior of the rotating housing, so that the rotating housing can absorb the heat and dissipate the heat naturally.

[0008] Preferably, the shock absorption mechanism includes a guide rod, a spring, and a connecting plate. Several sets of guide rods are provided, and the several sets of guide rods are movably inserted into the inner wall of the rotating shell in a ring shape. The spring is fixedly installed on the inner wall of the rotating shell near the guide rod, and the guide rod is fixedly installed on the side away from the rotating shell to the connecting plate. In this scheme, the cooperation of the guide rod, spring, and connecting plate can contact the thermally conductive sticker and conduct the heat on its surface to the rotating shell and the fixed shell, while also playing a shock absorption role.

[0009] Preferably, the driving mechanism includes a fixed plate, a servo motor, and a gear. The fixed plate is fixedly installed on one side of the bottom of the fixed housing. The top of the fixed plate away from the fixed housing is fixedly installed with the servo motor. The output end of the servo motor is fixedly installed with the gear. The gear meshes with the gear ring. In this scheme, the cooperation of the fixed plate, the servo motor, and the gear can drive the gear ring to rotate, thereby enabling it to achieve the effect of automatic rotation.

[0010] Preferably, the auxiliary components include an H-shaped ring, a fixed ring, and a roller. The H-shaped ring is fixedly installed on the surface of the steering column, and the top and bottom of the inner wall of the H-shaped ring are rotatably installed with the roller. The fixed ring is fixedly installed on the top of the inner wall of the rotating housing and rotatably installed on the inner wall of the H-shaped ring. In this scheme, the combined use of the H-shaped ring, the fixed ring, and the roller can make the rotating housing rotate more stably and smoothly, while also preventing noise from being generated when the rotating housing rotates.

[0011] Preferably, heat dissipation fins are fixedly installed on the surface of the fixed shell. In this design, the heat dissipation fins can naturally cool the surface temperature of the rotating shell and the fixed shell through contact with air, thereby ensuring that the temperature of the steering column is kept within a suitable range when it is working.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The adaptive damping adjustable intelligent road feel automotive steering column of this utility model, through the arrangement of a rotating shell, a toothed ring, a heat-conducting plate, and a heat-conducting sticker, enables the rotating shell and the toothed ring to rotate through a drive mechanism, thereby driving the damping mechanism to rotate, so that they can come into contact with the heat-conducting sticker to conduct heat away. The combination of the heat-conducting plate and the heat-conducting sticker can conduct the heat of the steering column during use to the interior of the rotating shell, so that the rotating shell can absorb the heat and dissipate it naturally.

[0014] 2. The adaptive damping adjustable intelligent road feel automotive steering column of this utility model, through the arrangement of guide rods, springs, connecting plates, fixing plates, servo motors and gears, enables the guide rods, springs and connecting plates to contact the heat-conducting sticker and conduct the heat on its surface to the rotating shell and the fixing shell, while also playing a shock-absorbing role. The fixing plate, servo motor and gears work together to drive the gear ring to rotate, thereby enabling it to achieve an automatic rotation effect. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, an adaptive damping-adjustable intelligent road-feeling steering column for automobiles includes a steering column 1; a fixed shell 2 is rotatably mounted on the surface of the steering column 1, a rotating assembly 3 is provided on the inner wall of the fixed shell 2, and a heat-conducting assembly 4 is provided on the side of the steering column 1 near the rotating assembly 3; a damping mechanism 5 is provided on the inner wall of the rotating shell 31, and a driving mechanism 6 is provided on one side of the fixed shell 2; an auxiliary assembly 7 is provided on the top of the inner wall of the rotating shell 31; the rotating assembly 3 includes a rotating shell 31 and a toothed ring 32, the rotating shell 31 is rotatably mounted on the inner wall of the fixed shell 2, and the bottom of the surface of the rotating shell 31 is fixedly mounted to the toothed ring 32; the heat-conducting assembly 4 includes a heat-conducting plate 41 and a heat-conducting sticker 42, several sets of heat-conducting plates 41 are provided, and several sets of heat-conducting plates 41 are fixedly mounted in a ring on the side of the steering column 1 near the rotating shell 31, and the side of the heat-conducting plate 41 away from the steering column 1 is fixedly mounted to the heat-conducting sticker 42; the damping mechanism 5 includes a guide rod 51, a spring 52, and a connecting rod 52. The plate 53 and guide rods 51 are provided in several sets. The several sets of guide rods 51 are movably inserted into the inner wall of the rotating shell 31 in a ring. The spring 52 is fixedly installed on the inner wall of the rotating shell 31 near the guide rods 51. The side of the guide rods 51 away from the rotating shell 31 is fixedly installed with the connecting plate 53. The drive mechanism 6 includes a fixed plate 61, a servo motor 62 and a gear 63. The fixed plate 61 is fixedly installed on one side of the bottom of the fixed shell 2. The top of the fixed plate 61 away from the fixed shell 2 is fixedly installed with the servo motor 62. The output end of the servo motor 62 is fixedly installed with the gear 63. The gear 63 meshes with the gear ring 32. The auxiliary component 7 includes an H-shaped ring 71, a fixed ring 72 and a roller 73. The H-shaped ring 71 is fixedly installed on the surface of the steering column 1. The top and bottom of the inner wall of the H-shaped ring 71 are rotatably installed with the roller 73. The fixed ring 72 is fixedly installed on the top of the inner wall of the rotating shell 31. The fixed ring 72 is rotatably installed on the inner wall of the H-shaped ring 71. The surface of the fixed shell 2 is fixedly installed with heat dissipation fins 80.

[0026] like Figures 1 to 5As shown, the engagement of the rotating shell 31 and the gear ring 32 enables rotation via the drive mechanism 6, which in turn drives the damping mechanism 5 to rotate, allowing it to contact the thermal conductive sticker 42 and conduct heat away. The engagement of the thermal conductive plate 41 and the thermal conductive sticker 42 conducts heat from the steering column 1 to the interior of the rotating shell 31, where it absorbs and dissipates the heat naturally. The engagement of the guide rod 51, spring 52, and connecting plate 53 allows them to contact the thermal conductive sticker 42 and conduct heat from its surface to the rotating shell 31 and... The fixed shell 2 also serves as a shock absorber. The combination of the fixed plate 61, servo motor 62, and gear 63 enables the drive ring 32 to rotate, thus achieving automatic rotation. The combination of the H-shaped ring 71, fixed ring 72, and roller 73 makes the rotating shell 31 more stable and smooth during rotation, while also preventing noise from generated during rotation. The heat dissipation fins 80 can naturally cool the surface temperature of the rotating shell 31 and the fixed shell 2 through contact with air, thereby ensuring that the temperature of the steering column 1 is kept within a suitable range during operation.

[0027] Working principle: During operation, the steering column 1 is first installed in the usage position and then put into use. During the use of the steering column 1, the adaptive damping generates a lot of heat. Therefore, the heat conduction plate 41 and the heat conduction sticker 42 will conduct the heat inside the steering column 1. Then, the user starts the servo motor 62 to drive the gear 63 to rotate. The rotation of the gear 63 will drive the gear ring 32 to rotate. The rotation of the gear ring 32 will drive the rotating shell 31 to rotate. When the rotating shell 31 rotates, it will drive the guide rod 51 and the connecting plate 53 to rotate. When the connecting plate 53 rotates, it will come into contact with the heat conduction sticker 42, thereby conducting the temperature of the surface of the heat conduction sticker 42 to the rotating shell 31. Then, the heat is dissipated through the heat dissipation fins 80 to ensure the normal operation of the adaptive damping. When the rotating shell 31 rotates, the fixing ring 72 will rotate synchronously with it. When the fixing ring 72 rotates, it will rotate inside the H-shaped ring 71. The roller 73 will make the rotation of the fixing ring 72 smoother and prevent friction or noise.
