Description

Technical Field

[0001] This utility model relates to the field of electric two-wheeled vehicle testing technology, and in particular to a multi-purpose testing platform for the steering mechanism of electric two-wheeled vehicles. Background Technology

[0002] Electric two-wheelers are widely used by consumers as a daily means of transportation. The basic structure of an electric two-wheeler includes the following parts: core mechanical system, electric drive system, control system, and safety auxiliary components. The core mechanical system is one of the most important components of an electric two-wheeler. As the core structural framework of the entire vehicle, it is responsible for supporting the body and connecting various parts. The core mechanical system includes components such as the frame structure, steering mechanism, and suspension system. The steering mechanism, as a crucial component of an electric two-wheeler, is mainly used to connect the frame body and the front wheel, and control the steering angle of the front wheel to control and change the direction of travel. During vehicle use, there will be continuous relative rotation between the steering mechanism and the frame, and the connection between the two will experience continuous friction and wear. Over long-term use, the steering mechanism will experience wear and interference, which will affect the smoothness of handling and steering angle, and even affect driving safety. Therefore, before the vehicle leaves the factory, it is essential to ensure the quality and service life of the steering mechanism, requiring durability testing and steering angle measurement. In the current technology, there is a lack of dedicated testing tools for this type. Measurements and tests are generally carried out manually, which is labor-intensive, inefficient, and prone to errors. Utility Model Content

[0029] like Figure 1 As shown, a multi-purpose testing platform for the steering mechanism of an electric two-wheeled vehicle includes a platform 1, a rear wheel fixing mechanism 3 and a front wheel positioning mechanism 4 mounted on the platform 1, and a durability testing mechanism 2 mounted above the platform 1.

[0030] like Figure 2 As shown, the durability testing mechanism 2 includes a base 21, a rotary motor 22, a transmission link, and a handlebar fixing device. The base 21 is fixedly mounted above the platform 1. The rotary motor 22 is fixedly connected to the base 21. The transmission link includes a first transmission link 23, a second transmission link 24, and a third transmission link 25 that are rotatably connected in sequence. One end of the first transmission link 23 is fixedly connected to the output shaft 26 of the rotary motor 22, and one end of the third transmission link 25 is rotatably connected to the base 21. The handlebar fixing device is fixedly connected to the end of the third transmission link 25 and is used to connect the handlebars of the electric two-wheeled vehicle to be tested. When the rotary motor 22 is started, the output shaft 26 drives the first transmission link 23 to rotate, and the second transmission link 24 drives the third transmission link 25 to swing back and forth.

[0031] Preferably, a gantry frame 5 is provided above the platform 1, and the base 21 of the durability testing mechanism 2 is fixedly connected to the gantry frame 5. The gantry frame 5 serves as a stable support platform, which can provide stable support for the durability testing mechanism 2 and prevent the transmission linkage from shaking during the movement.

[0032] Preferably, the handlebar fixing device includes a plurality of connecting rods 27 and connectors 28, which are connected alternately in sequence and can be disassembled or extended to adapt to different specifications of electric two-wheelers.

[0033] Preferably, the durability testing mechanism 2 further includes a frequency regulator 29, which is connected to the rotary motor 22 and can change the rotation speed of the output shaft 26 of the rotary motor 22, thereby adjusting the test conditions for the durability test of the vehicle steering mechanism.

[0034] like Figure 3 As shown, the rear wheel fixing mechanism 3 includes a first rear clamping plate 31, a second rear clamping plate 32, and a clamping plate fixing seat 33. The first rear clamping plate 31 and the clamping plate fixing seat 33 are both fixedly connected to the platform 1, and the second rear clamping plate 32 is movably connected to the clamping plate fixing seat 33. The first rear clamping plate 31 and the second rear clamping plate 32 are arranged opposite each other and the distance between them is adjustable.

[0035] To facilitate adjustment of the distance between the first rear clamping plate 31 and the second rear clamping plate 32, the rear wheel fixing mechanism 3 also includes a rotating wheel 34, a screw 35, and a nut 36. The nut 36 is fixedly connected to the clamping plate fixing seat 33, the screw 35 is threadedly connected to the nut 36, the rotating wheel 34 is fixedly connected to one end of the screw 35, and the other end of the screw 35 is connected to the second rear clamping plate 32. When the rotating wheel 34 is rotated, the screw 35 moves back and forth along the nut 36, and the second rear clamping plate 32 connected to the screw 35 also moves accordingly, thereby changing the distance between the first rear clamping plate 31 and the second rear clamping plate 32.

[0036] Preferably, the rear wheel fixing mechanism 3 further includes a guide rod 37 and a guide sleeve 38. The guide sleeve 38 is fixedly connected to the clamping plate fixing seat 33, and the guide rod 37 is slidably connected inside the guide sleeve 38. The second rear clamping plate 32 is fixedly connected to one end of the guide rod 37. Two sets of guide rods 37 and guide sleeves 38 are provided. With the support and guidance of the guide rods 37 and guide sleeves 38, the second rear clamping plate 32 can move more smoothly and steadily during its forward and backward movement.

[0037] like Figure 4 As shown, the front wheel positioning mechanism 4 includes a base plate 41, side end plates 42, and a front end plate 43. The base plate 41 is rotatably connected to the platform 1, the side end plates 42 are fixedly connected to the left and right sides of the base plate 41, and the front end plate 43 is fixedly connected to the front side of the base plate 41. The base plate 41, side end plates 42, and front end plate 43 form a semi-enclosed space for accommodating the front wheel, and can rotate as the front wheel rotates.

[0038] Preferably, an angle scale 6 is provided on the platform 1, the angle scale 6 is located at the front end of the front wheel positioning mechanism 4, and an angle pointer 7 is provided at the front end of the base plate 41. The angle pointer 7 can point to different scales on the angle scale 6 as the base plate 71 rotates, and is used to indicate the rotation angle of the front wheel.

[0039] The specific working process and principle of the above embodiments are as follows:

[0040] First, the two-wheeled electric vehicle is placed on platform 1, with the front wheel on base plate 41 and the rear wheel between the first rear clamp plate 31 and the second rear clamp plate 32. Rotating wheel 34 causes screw 35 to move back and forth along nut 36, and the second rear clamp plate 32, connected to screw 35, also moves accordingly until the rear wheel is fixed between the first and second rear clamp plates 31 and 32. Then, based on the distance between the handlebars and the durability testing mechanism, the number of connecting rods 37 and connecting pieces 38 is adjusted to ensure they can be connected to the handlebars. Next, the rotary motor 22 is started. The first transmission link 23 begins to rotate under the drive of the output shaft 26 of the rotary motor 22. The second transmission link 24 converts the rotational motion of the first transmission link 23 into a reciprocating motion at its end, and drives the third transmission link 25 to swing left and right around the connection point on base 21. This, in turn, drives the vehicle's steering mechanism to continuously perform left and right steering actions through the handlebar fixing device. To test the durability of the steering mechanism at different steering rates, the rotation speed of the output shaft 26 of the rotary motor 22 can be changed by adjusting the frequency regulator 29. By observing whether the steering angle of the front wheels meets the standard, the angle scale needle 7 points to the maximum mark on the angle scale 6 as the base plate 41 rotates.

[0041] The above specific embodiments are only for illustrating the technical concept and structural features of this utility model, and are intended to enable those skilled in the art to implement them. However, the above content does not limit the protection scope of this utility model. Any equivalent changes or modifications made in accordance with the spirit and essence of this utility model shall fall within the protection scope of this utility model.
