Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary robots, and more particularly to an auxiliary driving robot. Background Art

[0002] Automobile performance tests refer to the performance tests of automobiles under the condition of not disassembling the vehicle. The items mainly include power performance tests, fuel economy tests, braking performance tests, ride comfort tests, handling stability tests, coasting tests, reliability inspection tests, etc. With the progress of science and technology, the test methods have gradually changed from field road tests to indoor simulated road tests. Field road tests are close to the actual situation, but are affected by road conditions, wind direction, wind speed, driver skills and other conditions, with poor repeatability. Indoor simulated road tests are easy to control test conditions with new technologies, have good repeatability, are simple to test, and can save test time and costs.

[0003] In the related art, since there are great safety hazards during automobile performance tests, in order to avoid injuries to test personnel during the tests, auxiliary driving equipment is generally used to assist in turning the steering wheel to complete the tests. By replacing manual operation with auxiliary driving equipment, the situation of personnel being injured during the tests is directly avoided.

[0004] However, although there are various devices for automobile auxiliary driving currently, there are still certain problems. For example, currently during auxiliary driving, in order to meet the turning effect of the steering wheel, cylinders are generally arranged on both sides of the steering wheel, and the steering wheel is driven to turn by the telescoping of the cylinders. Although this method can meet part of the test requirements, the amplitude of the steering wheel that the cylinders can drive is small and cannot achieve large-amplitude turning, which results in the inability to conduct some tests that require large-amplitude turning of the steering wheel, and there are certain limitations.

[0005] Therefore, in view of the above technical problems, it is necessary to provide an auxiliary driving robot. Summary of the Invention

[0006] The purpose of the present invention is to provide an auxiliary driving robot, which can solve the problem that the current auxiliary driving equipment cannot turn the steering wheel in a large amplitude, resulting in the inability to conduct some driving tests.

[0032] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] An embodiment of the present application discloses an assisted driving robot.

[0034] Referring to Figure 1 and Figure 2 , an assisted driving robot includes a supporting ring 1, a driven ring 2, a transmission mechanism 3, a steering wheel clamping plate 4 and a support mechanism 5. The inner ring of the supporting ring 1 is rotatably connected to the driven ring 2, and the driven ring 2 is coaxially arranged with the supporting ring 1. The transmission mechanism 3 is arranged on the supporting plate 1. The steering wheel clamping plate 4 is connected inside the transmission mechanism 3. The support mechanism 5 is arranged between the supporting ring 1 and the windshield of the vehicle.

[0035] In the present invention, by providing the transmission mechanism 3, the steering wheel clamping plate 4 and the support mechanism 5, the transmission mechanism 3 as a whole is clamped and fixed on the vehicle steering wheel through the steering wheel clamping plate 4. The servo motor 32 in the transmission mechanism 3 drives the driving gear 33 to rotate, and through the linkage gear disk 35, the driven gear 34 can be synchronously meshed and linked, thereby driving the vehicle steering wheel to deflect. When the vehicle is undergoing a test, it can deflect significantly, and at the same time, through an external electronic control device, the rotation amplitude of the vehicle steering wheel can also be accurately controlled, greatly improving the accuracy of the test while eliminating the limitation that the vehicle steering wheel cannot rotate significantly.

[0036] The support mechanism 5 is used to support and position the supporting ring 1, so that when the driven ring 2 rotates, it can provide a reverse supporting force, thereby driving the vehicle steering wheel to rotate, avoiding the overall synchronous rotation of the supporting ring 1 and the vehicle steering wheel, which is simple, efficient and practical.

[0037] Refer to Figure 3 and Figure 4 In this embodiment, the transmission mechanism 3 includes a base 31, a servo motor 32, a driving gear 33, a driven gear 34 and a linkage disk 35. The servo motor 32 drives the driving gear 33 to rotate, and makes the linkage disk 35 engage and link, thereby driving the driven gear 34 to synchronously engage and link, and then driving the vehicle steering wheel to rotate through the driven ring 2.

[0038] The base 31 is fixed at the edge of the supporting plate 1. The servo motor 32 is fixed on the base 31 and electrically connected to an external electronic control device. The driving gear 33 is coaxially fixed on the output shaft of the servo motor 32. The driven gear 34 is coaxially fixed at the bottom of the driven ring 2. The linkage disk 35 is rotatably connected to the base 31, and the linkage disk 35 meshes between the driving gear 33 and the driven gear 34. A steering wheel clamp 4 is connected to the bottom of the driven gear 34.

[0039] Specifically, two linkage disks 35 are arranged in parallel, and both of the two linkage disks 35 mesh between the driving gear 33 and the driven gear 34.

[0040] In the present invention, through the synchronous engagement and linkage of the two linkage disks 35, the transmission stability between the driving gear 33 and the driven gear 34 is improved.

[0041] In this embodiment, a plurality of steering wheel clamps 4 are arranged at the bottom of the driven gear 34, and the plurality of driven gears 34 are equidistantly arranged. The steering wheel clamp 4 is adjustably connected to the driven gear 34 by screws, and a strip-shaped notch is provided on the driven gear 34. The screws are slidably clamped in the strip-shaped notch of the driven gear 34 and locked by nuts.

[0042] In the present invention, the firmness of the connection between the driven gear 34 and the vehicle steering wheel is improved by a plurality of steering wheel clamps 4, and the position of the steering wheel clamp 4 on the driven gear 34 can be appropriately adjusted through the setting of the strip-shaped notch to meet vehicle steering wheels of different sizes.

[0043] Refer to Figure 5 and Figure 6 In this embodiment, regarding the support mechanism 5, 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 supporting ring 1, so that when the driven ring 2 rotates, the supporting ring 1 can provide a reverse acting force.

[0044] The docking plate 51 is arranged on the supporting ring 1. One ends of the first support rod 52 and the second support rod 54 are respectively connected to two ends of the connecting sleeve 53, and the other end of the first support rod 52 is connected to the docking plate 51, and the other end of the second support rod 54 is connected to the suction cup 55, and the suction cup 55 adsorbs on the automobile windshield.

[0045] Specifically, the support mechanism 5 further includes a ball head 56 and a ball head sleeve 57. The ball head 56 is respectively fixed on the docking plate 51 and the suction cup 55. The ball head sleeves 57 are respectively arranged at one ends of the first support rod 52 and the second support rod 54 away from the connecting sleeve 53, and the ball head sleeves 57 are rotatably sleeved on the ball head 56, so that the overall support angle of the support mechanism 5 can be adjusted at multiple angles through the ball head.

[0046] In the embodiment of the present application, a threaded hole is penetrated in the connecting sleeve 53. Threads are arranged on the outer walls of the first support rod 52 and the second support rod 54. The first support rod 52 and the second support rod 54 are in threaded cooperation with the threaded hole through the threads, and two groups of direction threads are symmetrically arranged in the threaded hole in the connecting sleeve 53.

[0047] In the present invention, through the arrangement of the threads, when the connecting sleeve 53 rotates, it can drive the first support rod 52 and the second support rod 54 to perform synchronous threaded linkage, thereby adjusting the overall support length of the support mechanism 5.

[0048] The suction cup 55 is composed of three combinations to form an integral structure, and the suction cup 55 is integrally in an equilateral triangle structure, and the stability of the suction cup 55 during adsorption is improved through the triangular structure.

[0049] Specifically, a pulley 6 is rotatably connected to the inner side of the supporting ring 1, a chute 7 is concavely arranged on the outer side of the driven ring 2, and the pulley 6 is rollingly clamped in the chute 7.

[0050] In the present invention, the rotation of the pulley 6 enables the driven ring 2 to rotate on the inner side of the supporting ring 1.

[0051] An adjusting handle 8 is rotatably connected to the driven ring 2. The adjusting handle 8 is in a spherical structure. Through the adjusting handle 8, it is convenient for the staff to pre-adjust the driven ring 2, thereby realizing the pre-adjustment of the angle of the automobile steering wheel.
