Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of assistive robots, and in particular to an assistive driving robot. Background Technology
[0002] Automotive performance testing refers to the performance tests conducted on vehicles without disassembling them. The main items include power performance testing, fuel economy testing, braking testing, ride comfort testing, handling stability testing, coasting testing, and reliability testing. With the advancement of science and technology, testing methods have gradually shifted from off-road testing to indoor simulated road testing. Off-road testing is close to reality, but it is affected by road conditions, wind direction, wind speed, driver skills, and other factors, resulting in poor repeatability. Indoor simulated road testing can easily use new technologies to control test conditions, has good repeatability, is simple to test, and can save test time and costs.
[0003] In related technologies, due to the significant safety hazards during vehicle performance testing, driver assistance devices are generally used to assist in turning the steering wheel to complete the test in order to prevent test personnel from being injured during the test. By replacing manual operation with driver assistance devices, the occurrence of personnel injury during the test can be directly avoided.
[0004] However, while there are various types of devices for assisted driving in automobiles, there are still some problems. For example, in order to achieve the desired steering wheel rotation effect, cylinders are usually placed on both sides of the steering wheel. The extension and retraction of the cylinders drive the steering wheel to rotate. Although this method can meet some testing requirements, the range of steering wheel rotation that the cylinders can drive is relatively small, and it cannot achieve large-scale rotation. This makes it impossible to conduct some tests that require large-scale steering wheel rotation, which has certain limitations.
[0005] Therefore, in order to address the aforementioned technical problems, it is necessary to provide an assisted driving robot. Utility Model Content
[0006] The purpose of this invention is to provide a driver assistance robot that can solve the problem that current driver assistance devices cannot turn the steering wheel significantly, thus making some driving tests impossible.
[0007] The assisted driving robot provided by this utility model adopts the following technical solution:

[0032] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0033] This utility model discloses an assisted driving robot.
[0034] Reference Figure 1 and Figure 2 An assisted driving robot includes a support ring 1, a driven ring 2, a transmission mechanism 3, a steering wheel clamp 4, and a support mechanism 5. The inner ring of the support ring 1 is rotatably connected to the driven ring 2, and the driven ring 2 is coaxially arranged with the support ring 1. The transmission mechanism 3 is arranged on the support plate 1, the steering wheel clamp 4 is connected in the transmission mechanism 3, and the support mechanism 5 is arranged between the support ring 1 and the windshield of the car.
[0035] In this utility model, a transmission mechanism 3, a steering wheel clamp 4, and a support mechanism 5 are set up. The transmission mechanism 3 is clamped and fixed to the car steering wheel by the steering wheel clamp 4. The servo motor 32 in the transmission mechanism 3 drives the drive gear 33 to rotate, and the driven gear 34 can be synchronously meshed and linked by the linkage gear plate 35, thereby causing the car steering wheel to deflect. This allows the car to deflect significantly during the test. At the same time, the rotation amplitude of the car steering wheel can be precisely controlled by the external electronic control equipment, which greatly improves the accuracy of the test and eliminates the limitation that the car steering wheel cannot rotate significantly.
[0036] The support mechanism 5 is used to support and limit the support ring 1, so that the driven ring 2 can provide reverse support force when it rotates, thereby driving the car steering wheel to rotate. This avoids the support ring 1 rotating synchronously with the car steering wheel, which is simple, efficient and practical.
[0037] Reference Figure 3 and Figure 4 In this embodiment, the transmission mechanism 3 includes a base 31, a servo motor 32, a drive gear 33, a driven gear 34, and a linkage gear 35. The servo motor 32 drives the drive gear 33 to rotate, and the linkage gear 35 engages and links, thereby driving the driven gear 34 to engage and link synchronously, and then driving the car steering wheel to rotate through the driven ring 2.
[0038] The base 31 is fixed to the edge of the support tray 1. The servo motor 32 is fixed on the base 31 and electrically connected to the external electrical control equipment. The drive gear 33 is coaxially fixed on the output shaft of the servo motor 32. The driven gear 34 is coaxially fixed to the bottom of the driven ring 2. The linkage gear 35 is rotatably connected to the base 31 and meshes between the drive gear 33 and the driven gear 34. The bottom of the driven gear 34 is connected to the steering wheel clamp 4.
[0039] Specifically, there are two linkage gear disks 35 arranged side by side, and both linkage gear disks 35 are meshed between the driving gear 33 and the driven gear 34.
[0040] In this invention, the synchronous meshing of two linkage gear discs 35 improves the stability of the transmission between the driving gear 33 and the driven gear 34.
[0041] In this embodiment, the steering wheel clamp 4 is provided with multiple driven gears 34 at the bottom, and the multiple driven gears 34 are all equally spaced. The steering wheel clamp 4 is connected to the driven gears 34 in an adjustable manner by screws, and a strip-shaped slot is provided on the driven gear 34. The screws are slidably engaged in the strip-shaped slot of the driven gear 34 and locked by nuts.
[0042] In this invention, multiple steering wheel clamps 4 are used to improve the firmness of the connection between the driven gear 34 and the car steering wheel, and the position of the steering wheel clamps 4 on the driven gear 34 can be appropriately adjusted by the setting of the strip groove to meet the needs of car steering wheels of different sizes.
[0043] Reference Figure 5 and Figure 6 In this embodiment, the support mechanism 5 includes a docking plate 51, a first support rod 52, a connecting sleeve 53, a second support rod 54, and a suction cup 55. The support mechanism 5 supports the entire support ring 1, so that the support ring 1 can provide a reverse force when the driven ring 2 rotates.
[0044] The docking plate 51 is set on the support ring 1. One end of the first support rod 52 and the second support rod 54 are respectively connected to the two ends of the connecting sleeve 53, and the other end of the first support rod 52 is connected to the docking plate 51. The other end of the second support rod 54 is connected to the suction cup 55, which is attached to the windshield of the car.
[0045] Specifically, the support mechanism 5 also includes a ball head 56 and a ball head sleeve 57. The ball head 56 is fixed on the docking plate 51 and the suction cup 55 respectively. The ball head sleeve 57 is respectively set on the first support rod 52 and the second support rod 54 at the end away from the connecting sleeve 53. The ball head sleeve 57 is rotatably sleeved on the ball head 56. The ball head allows the overall support angle of the support mechanism 5 to be adjusted at multiple angles.
[0046] In this embodiment of the utility model, a threaded hole is provided through the connecting sleeve 53, and the outer walls of the first support rod 52 and the second support rod 54 are both provided with threads. The first support rod 52 and the second support rod 54 are threadedly engaged with the threaded hole through the threads, and the threaded hole in the connecting sleeve 53 is symmetrically provided with two sets of directional threads.
[0047] In this utility model, the threaded arrangement enables the connecting sleeve 53 to drive the first support rod 52 and the second support rod 54 to move synchronously and threadedly when rotating, thereby adjusting the overall support length of the support mechanism 5.
[0048] The suction cup 55 is composed of three parts forming an integral structure, and the suction cup 55 as a whole has an equilateral triangle structure, which improves the stability of the suction cup 55 when adsorbing.
[0049] Specifically, a pulley 6 is rotatably connected to the inner side of the supporting ring 1, and a groove 7 is recessed on the outer side of the driven ring 2, with the pulley 6 rolling and engaging in the groove 7.
[0050] In this invention, the driven ring 2 can rotate inside the supporting ring 1 by rotating the pulley 6.
[0051] An adjustment handle 8 is rotatably connected to the driven ring 2. The adjustment handle 8 has a spherical structure. The adjustment handle 8 allows the operator to pre-adjust the driven ring 2, thereby achieving pre-adjustment of the steering wheel angle.
