Description

Technical Field

[0001] The utility model relates to the technical field of testing devices, in particular to an adjustable tooling for fixing a whole vehicle road simulation steering wheel. Background Art

[0002] During the road simulation test of the whole vehicle, based on the development of automobile durability performance, the whole vehicle needs to be subjected to road simulation bench test, which requires ensuring that the steering wheel is locked, that is, the vehicle steering wheel needs to be fixed in order to form a fixed reaction force for the steering rod to avoid damage to the vehicle steering system and the vehicle itself caused by the steering wheel turning left and right during the test, as well as unnecessary damage to the test equipment. At present, laboratories often use straps to fix the steering wheel when conducting tests. However, this type of fixing method is easy to loosen in the case of long-term vibration durability tests, causing the left and right front wheels of the vehicle to deviate left and right, which is easy to cause data deviations and insufficient test accuracy.

[0003] In addition, due to the differences in the steering wheel structures of different models, ordinary locking devices cannot be applied to all types of steering wheels. As a result, in the process of fixing the steering wheel, different vehicle steering wheels have different sizes and shapes, and different tooling needs to be processed each time to adapt to different steering wheels, resulting in a huge waste of resources and affecting test efficiency. At present, a universal and reliable tooling is urgently needed to ensure the locking of the steering wheel. Utility Model Content

[0004] The utility model aims to provide an adjustable tooling for fixing a whole vehicle road simulation steering wheel, which has a simple and reliable structure, can stably lock the steering wheel, and has an adjustable structure, can meet the fixing requirements of steering wheels of different sizes, and has universality.

[0005] The basic scheme provided by the utility model is: an adjustable tooling for fixing a whole vehicle road simulation steering wheel, comprising a positioning square plate, a steering wheel buckle and an auxiliary mechanism; the positioning square plate is provided with an adjustment through slot; the steering wheel buckle comprises an upper buckle and a lower buckle; a positioning hole is provided on the bottom surface of the lower buckle, and is connected to the adjustment through slot through the positioning hole and a positioning bolt; locking holes are correspondingly provided on the upper buckle and the lower buckle; the inner surfaces of the upper buckle and the lower buckle are both arc surfaces, so as to fit the shape of the steering wheel;

[0006] The positioning square plate is also symmetrically provided with two fixing buckles; the auxiliary mechanism includes a first transverse fixing rod and a longitudinal fixing rod; the first transverse fixing rod is connected to the positioning square plate through the fixing buckle; the two ends of the first transverse fixing rod are respectively connected to a longitudinal fixing rod.

[0007] Furthermore, there are four adjustment slots and steering wheel buckles, which are evenly distributed at the four corners of the positioning square plate.

[0008] Furthermore, the center line of the adjustment slot is parallel to the diagonal line of the positioning square plate.

[0009] Furthermore, both ends of the first transverse fixing rod are connected to the upper end of the longitudinal fixing rod through rod connectors respectively.

[0010] Furthermore, the auxiliary mechanism also includes a second transverse fixing rod; both ends of the second transverse fixing rod are respectively connected to the lower end of the longitudinal fixing rod through a rod connector.

[0011] Furthermore, a supporting rib is fixedly provided at the lower end of the longitudinal fixing rod.

[0012] Furthermore, two groups of locking holes are symmetrically provided on the upper buckle and the lower buckle.

[0013] Furthermore, the fixing buckle is arranged on the center line of the positioning square plate.

[0014] Furthermore, the auxiliary mechanism also includes a seat fixing device; the seat fixing device includes a connecting rod and a seat fixing frame; one end of the connecting rod is used to connect with the first transverse fixing rod, and the other end of the connecting rod is used to connect with the seat fixing frame.

[0015] Furthermore, the seat fixing frame includes an upper frame body and a lower frame body; a left support rod group and a right support rod group are connected between the upper frame body and the lower frame body; a connecting groove is provided on the right support rod group; one end of the connecting rod is connected to the connecting groove through a switching mechanism.

[0016] The working principle and advantages of the utility model are as follows: when the steering wheel needs to be fixed, first adjust the position of the steering wheel buckle on the positioning square plate, and by moving the steering wheel buckle on the adjustment slot and adjusting the locking position of the positioning bolt, the locking range of the steering wheel buckle can be relatively expanded or reduced to match the size of the steering wheel; then the steering wheel buckle is used to lock the steering wheel. Then the auxiliary mechanism is fixed to the positioning square plate, and the longitudinal fixing rod of the auxiliary mechanism can be against the ground (the bottom surface of the driver's seat area), thereby limiting the positioning square plate and completing the locking of the steering wheel.

[0017] The overall structure of the utility model is simple and easy to disassemble and assemble. The positioning square wheel, steering wheel buckle and auxiliary mechanism cooperate to fully lock the steering wheel, and the locking is stable. It can ensure that the steering wheel does not loosen under the condition of long-term vibration durability test, and meet the accuracy and consistency requirements of the whole vehicle road simulation test. In particular, this scheme is different from the traditional fixed tooling. Since the steering wheel diameters of different models are often different, the traditional fixed tooling is difficult to apply to all steering wheel fixing scenarios, resulting in different steering wheels. Different fixed tooling needs to be used separately, resulting in low tooling utilization rate, high test cost and other problems. However, this scheme does not have the above problems. The position of the steering wheel buckle used to lock the steering wheel is adjustable, which can meet the fixing requirements of steering wheels of different sizes. It has universality, helps to reduce test costs and improve test efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Embodiment 1

[0030] The embodiment is basically as shown in the attached Figure 1 As shown: an adjustable tooling for fixing a vehicle road simulation steering wheel 6, comprising a positioning square wheel 1, a steering wheel buckle 2 and an auxiliary mechanism 3.

[0031] The positioning square plate 1 is provided with an adjustment slot 11; Figure 3 As shown, the steering wheel buckle 2 includes an upper buckle 21 and a lower buckle 22; a positioning hole is provided at the center of the bottom surface of the lower buckle 22, and the lower buckle 22 is detachably connected to the adjustment slot 11 through the positioning hole and the positioning bolt 23; and the head diameter of the positioning bolt 23 is larger than the width of the adjustment slot 11, and the rod diameter of the positioning bolt 23 is smaller than the width of the adjustment slot 11. Tightening the positioning bolt 23 can fix the relative position of the steering wheel buckle 2 and the adjustment slot 11; loosening the positioning bolt 23 can move the steering wheel buckle 2 to adjust the relative position of the steering wheel buckle 2 and the adjustment slot 11.

[0032] The upper buckle 21 and the lower buckle 22 are provided with locking holes correspondingly; and the locking holes are symmetrically provided in two groups. The inner surfaces of the upper buckle 21 and the lower buckle 22 are both arc surfaces to fit the shape of the steering wheel 6. In this embodiment, when the upper buckle 21 and the lower buckle 22 are locked, their inner surfaces form a circular hollow space to facilitate clamping the steering wheel 6.

[0033] Moreover, in this embodiment, the adjusting slots 11 and the steering wheel buckles 2 are both provided with 4, and are evenly distributed at the four corners of the positioning square plate 1; the center line of the adjusting slots 11 is parallel to the diagonal line of the positioning square plate 1. With this structure, the steering wheel 6 can be locked from four directions, and the locking is more stable, which can ensure the reliable locking of the steering wheel 6 and help to ensure the test accuracy of the whole vehicle test. And through the cooperation of the 4 adjusting slots 11, the positioning square plate 1 can have a larger adjustment space, and can thus adapt to steering wheels 6 of different diameters. The positioning square plate 1 in this embodiment can be adapted to steering wheels 6 with a diameter of 310mm to 400mm.

[0034] like Figure 2 As shown, the positioning square plate 1 is symmetrically provided with two fixing buckles 12; the fixing buckles 12 are arranged on the center line of the positioning square plate 1. In this embodiment, the fixing buckle 12 is provided with a first clamping hole 122 for the rod to pass through, one side of the first clamping hole 122 is connected to the first slot 123, and the first fixing holes 121 are provided on both walls of the first slot 123.

[0035] The auxiliary mechanism 3 includes a first transverse fixing rod 31, a longitudinal fixing rod 32, and a second transverse fixing rod 33. The first transverse fixing rod 31 is connected to the positioning square plate 1 through a fixing buckle 12; specifically, the first transverse fixing rod 31 passes through the fixing buckle 12. The two ends of the first transverse fixing rod 31 are respectively connected to the upper end of a longitudinal fixing rod 32 through a rod connector 4. The two ends of the second transverse fixing rod 33 are respectively connected to the lower end of the longitudinal fixing rod 32 through a rod connector 4. Figure 4 As shown, the rod connecting member 4 includes a transverse connecting portion and a longitudinal connecting portion that are integrally connected; the transverse connecting portion includes a transverse through hole 41 and a second slot 42 connected thereto, and second fixing holes 43 are provided on both walls of the second slot 42; the longitudinal connecting portion includes a longitudinal through hole 44 and a third slot 45 connected thereto, and third fixing holes 46 are provided on both walls of the slot.

[0036] Specifically, a support rib 321 is fixedly provided at the lower end of the longitudinal fixing rod 32. With this structure, the longitudinal fixing rod 32 can be placed stably.

[0037] In a specific application, first, the lower buckle 22 of the steering wheel buckle 2 is fixed to the positioning square plate 1 through the adjustment slot 11, and then the steering wheel buckle 2 is connected to the steering wheel 6 to be fixed, and the locking bolt 24 is used to lock the upper buckle 21 and the lower buckle 22 through the locking hole, thereby locking the steering wheel 6. Then, the first transverse fixing rod 31 is passed through the fixing buckle 12, and the bolt is used to pass through the fixing hole of the fixing buckle 12 to lock the first transverse fixing rod 31, so that the first transverse fixing rod 31 is not easy to shake in the fixing buckle 12. The rod connector 4 is used to connect the longitudinal fixing rod 32 and the second transverse fixing rod 33, thereby completing the installation of the overall tooling.

[0038] In the above process, if the size of the steering wheel 6 does not correspond to the current position of the steering wheel buckle 2, the positioning bolt 23 can be loosened to adjust the relative position of the steering wheel buckle 2 and the adjustment slot 11 so that the steering wheel buckle 2 is relatively far away from the center of the positioning square disc 1 or relatively close to the center of the positioning square disc 1 to match the size of the steering wheel 6.

[0039] The present embodiment provides an adjustable tooling for fixing the road simulation steering wheel 6 of the whole vehicle, which has a simple and reliable structure, can stably lock the steering wheel 6, and has an adjustable structure, which can meet the fixing requirements of steering wheels 6 of different sizes and has universality.

Then, the first transverse fixing rod 31 is passed through the fixing buckle 12, and the bolt is used to pass through the fixing hole of the fixing buckle 12 to lock the first transverse fixing rod 31, so that the first transverse fixing rod 31 is not easy to shake in the fixing buckle 12. The longitudinal fixing rod 32 and the second transverse fixing rod 33 are connected by the rod connector 4, and then the seat fixing device 5 is assembled to complete the installation of the overall tooling.

[0045] During assembly of the seat fixing device 5 , the fixing height of the adapter mechanism 53 on the right support rod group 524 can be adjusted according to the spacing distance between the seat 7 and the steering wheel 6 , so that the connecting rod 51 can connect the first transverse fixing rod 31 and the seat fixing frame 52 .
