Description

Technical Field

[0001] This application relates to the technical field of electric vehicle testing, and more particularly to a wheel steering testing device. Background Technology

[0002] As a common short-distance transportation and freight vehicle, the precision of the front-wheel steering system of electric tricycles directly affects driving safety and handling stability. In actual driving, deviations in front-wheel steering can lead to vehicle trajectory deviations and sluggish steering response, especially when turning, avoiding obstacles, or in complex road conditions, easily causing rollovers, collisions, and other safety accidents. At the same time, precise front-wheel steering ensures the stability of the electric tricycle when driving in a straight line, reduces abnormal tire wear, extends vehicle lifespan, and improves passenger comfort. Therefore, a precise front-wheel steering test must be performed after the electric tricycle is assembled.

[0003] When using existing electric tricycle wheel steering testing devices, staff push the electric tricycle onto the testing platform. All three wheels move within the limiting channels set on the platform to ensure the tricycle's body does not tilt during testing, thus guaranteeing the steering accuracy of the front wheels. Next, the front wheel moves to the steering testing platform and abuts against the positioning rod. The front wheel, now centered on the platform, is then rotated, causing the front wheel to turn. The steering angle of the front wheel is then measured and recorded, completing the wheel steering test.

[0004] However, in the above testing methods, when conducting wheel steering tests on different types of electric tricycles, it is necessary to replace the steering test platform for the front wheel separately (that is, when the front wheel abuts against the positioning rod on the corresponding steering test platform, the front wheel can be located in the center of the steering test platform), and it is also necessary to adjust the position of the two limit channels of the rear wheel (the distance between the two rear wheels is different for different types of electric tricycles) to make it suitable for the corresponding type of electric tricycle. Therefore, the adjustment of different models is time-consuming and laborious, which will affect the work efficiency of wheel steering tests. Summary of the Invention

[0019] Embodiments of this application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. Rather, embodiments of this application include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0020] The wheel steering test apparatus of this application embodiment will now be described with reference to the accompanying drawings.

[0021] like Figures 1-6 As shown, the wheel steering test device of this application embodiment includes an adjustment platform 1, a front wheel platform 2, a rear wheel contact limiting component 3, a rear wheel contact control component 4, a lifting drive component 5, a detection frame 6, a center adjustment component 7, and an angle detection component 8.

[0022] The adjustment platform 1 has a first front wheel limiting channel 11 in the middle, and a rear wheel adjustment plate 10 is slidably arranged on the adjustment platform 1 and located in the rear wheel adjustment groove 12 opened on the adjustment platform 1.

[0023] In this embodiment of the application, the rear wheel adjustment plate 10 is used to adjust the position of the rear wheel of the electric tricycle, so as to ensure the test position of the rear wheel of the electric tricycle, that is, after the rear wheel is straightened, the body position of the electric tricycle is straightened, so as to ensure that the electric tricycle will not be tilted during the testing process.

[0024] In this embodiment, the first front wheel limiting channel 11 is used to limit the front wheel platform 2.

[0025] The front wheel platform 2 is movably connected to the first front wheel limiting channel 11.

[0026] In this embodiment, the front wheel platform 2 is used to fix and limit the front wheel of the electric tricycle.

[0027] Specifically, the front wheel of the electric tricycle is pushed onto the front wheel platform 2, which limits the front wheel of the electric tricycle. The first front wheel limiting channel 11 limits the front wheel platform 2, thereby enabling the front wheel to run in a straight line, ensuring the stability of the electric tricycle and improving the steering accuracy of the front wheel.

[0028] The rear wheel abutment limiter 3 is slidably set on the top of the adjustment platform 1, and the rear wheel abutment limiter 3 passes through the control groove 13 opened on the adjustment platform 1 and slides abuts against the rear wheel abutment control member 4.

[0029] In this embodiment of the application, the rear wheel abutment limiting member 3 is used to abut and limit the two rear wheels of the electric tricycle, ensuring the straight sliding of the rear wheels of the electric tricycle, thereby ensuring that the electric tricycle will not tilt during the testing process.

[0030] The rear wheel abutment control component 4 is located at the bottom of the adjustment platform 1.

[0031] In this embodiment, the rear wheel contact control member 4 is used to control the rear wheel contact limiting member 3 to contact the two rear wheels of the electric tricycle.

[0032] The lifting drive component 5 is located on one side of the adjustment platform 1.

[0033] In this embodiment, the lifting drive 5 is used to control the lifting of the adjustment platform 1.

[0034] Specifically, after the lifting drive component 5 drives the adjustment platform 1 upward, the electric tricycle moves towards the center adjustment component 7 under the action of gravity (moving forward). After the lifting drive component 5 drives the adjustment platform 1 downward, the electric tricycle moves and returns to its initial position under the action of gravity (moving backward). The lifting drive component 5 facilitates the forward and backward movement of the electric tricycle.

[0035] The detection frame 6 is set on the other side of the adjustment platform 1 and is flush with the adjustment platform 1.

[0036] Understandably, the alignment of the detection frame 6 with the adjustment platform 1 facilitates the forward movement detection and the backward movement reset of the electric tricycle.

[0037] The center adjustment component 7 is set inside the detection frame 6 to adjust the center of the front wheel.

[0038] Understandably, the center adjustment component 7 can adjust the center of different types of front wheels so that the center of the electric tricycle's front wheel is on the same axis as the detection position, thereby ensuring the accuracy of the steering test.

[0039] The angle detection component 8 is connected to the center adjustment component 7 via a transmission connection, which drives the center adjustment component 7 to rotate and detects the angle of rotation.

[0040] Understandably, the data detected by the angle detection component 8 is transmitted to the controller (not shown in the figure) to complete the steering test of the front wheel of the electric tricycle.

[0041] Specifically, in actual operation, the relevant operators push the electric tricycle onto the adjustment platform 1, with the front wheel of the electric tricycle located on the front wheel platform 2. The front wheel platform 2 limits the front wheel of the electric tricycle, and the two rear wheels of the electric tricycle are located on the adjustment plate.

[0042] The controller controls the operation of the rear wheel contact control component 4, which in turn controls the rear wheel contact limit component 3 to extend and move equidistantly to the two rear wheels of the electric tricycle. If the electric tricycle is tilted, the equidistant movement of the rear wheel contact limit component 3 will adjust the position of the two rear wheels of the electric tricycle through the adjustment plate, thereby ensuring that the electric tricycle will not tilt during the testing process.

[0043] The controller controls the lifting drive component 5, which raises the adjustment platform 1. Under the action of gravity, the electric tricycle moves towards the center adjustment component 7. During the movement, the front wheel platform 2 limits the front wheel of the electric tricycle, and the rear wheel abutment limit component 3 limits the position of the two rear wheels of the electric tricycle, thereby continuously maintaining the stability of the electric tricycle and ensuring that the electric tricycle will not tilt during the inspection process.

[0044] The controller controls the center adjustment component 7 to adjust the center of the front wheel of the electric tricycle. After the adjustment is completed, the position of the front wheel is limited, the lifting drive component 5 returns to the initial position, and the angle detection component 8 tests the steering of the front wheel. After the test is completed, the lifting drive component 5 drives the adjustment platform 1 downward, and the electric tricycle returns to the initial position under the action of gravity, thus completing the wheel steering test.

[0045] In one embodiment of this application, such as Figure 2 , Figure 5 and Figure 6 As shown, the center adjustment assembly 7 includes two half-clamps 70, a rotating connector 71, a third hydraulic telescopic rod 72, and a clamp control frame 73.

[0046] One end of each of the two half-clamps 70 abuts against the detection frame 6, and the other ends of the two half-clamps 70 are connected by a rotating connector 71. The half-clamps 70 are provided with a second front wheel limiting channel 700, a front wheel baffle 701, and friction patterns. A support frame 720 is provided on the extension shaft of the third hydraulic telescopic rod 72. The rotating connector 71 is rotatably connected to the support frame 720. The bottom of the third hydraulic telescopic rod 72 is connected to the angle detection component 8. The clamp control frame 73 is located inside the detection frame 6, and the third hydraulic telescopic rod 72 is located inside the clamp control frame 73. The half-clamps 70 and the clamp control frame 73 slide against each other.

[0047] Specifically, by rotating the two halves of the clamping plate 70 together, when the third hydraulic telescopic rod 72 retracts, it is limited by the clamping plate control frame 73, causing the two halves of the clamping plate 70 to form a V-shape, thereby clamping the front wheel of the electric tricycle. The positions of the two halves of the clamping plate 70 are fixed, so that the center position of the front wheel of different types of electric tricycles is the same, thus enabling the device to be applicable to the detection of different types of wheels.

[0048] It is understandable that the friction texture can clamp the front wheel of the electric tricycle, and the front wheel baffle 701 (there are two front wheel baffles 701, which are set on both sides of the half clamp 70) further limits the position of the wheel, thereby ensuring the steering detection effect of the wheel.

[0049] In one embodiment of this application, such as Figure 5 and Figure 6 As shown, the rotating connector 71 includes a rotating shaft 711 and a plurality of sleeves 710.

[0050] Multiple sleeves 710 are respectively installed on the corresponding half of the clamping plate 70, and multiple sleeves 710 are respectively sleeved on the rotating shaft 711, and the rotating shaft 711 is rotatably connected to the support frame 720.

[0051] It should be noted that the rotating connector 71 can be any other rotatable connection component commonly found on the market, and is not limited here.

[0052] In one embodiment of this application, such as Figure 5 and Figure 6 As shown, the angle detection component 8 includes a drive motor 80, a torque limiter 81, and an angle sensor 82.

[0053] The drive motor 80 is located at the bottom of the detection frame 6, the torque limiter 81 is located inside the detection frame 6, the output shaft of the drive motor 80 is connected to one end of the torque limiter 81, the other end of the torque limiter 81 is connected to the third hydraulic telescopic rod 72, and the angle sensor 82 is located inside the detection frame 6 and is connected to the third hydraulic telescopic rod 72 in a transmission manner.

[0054] It should be noted that the torque limiter 81 and angle sensor 82 described in this embodiment are common components on the market and are existing technologies, and will not be described in detail here. In addition, the torque limiter 81 can idle after the overload torque of the drive motor 80 reaches a certain value (i.e., the overload torque formed when the wheel steering reaches its maximum value and the drive motor 80 continues to rotate), thereby preventing overload from damaging the relevant components of this device.

[0055] In one embodiment of this application, such as Figure 2 and Figure 4 As shown, the rear wheel abutment limiting member 3 includes two abutment plates 30 and multiple drive blocks 31.

[0056] Two abutment plates 30 are slidably mounted on the adjustment platform 1. Multiple rollers 300 are rotatably mounted on the abutment plates 30. Multiple drive blocks 31 are respectively mounted on the corresponding abutment plates 30. The drive blocks 31 pass through the control groove 13 and slide against the rear wheel abutment control member 4.

[0057] It should be noted that multiple control slots 13 are provided in this embodiment, and each is slidably connected to the corresponding drive block 31. In addition, the movement of the drive block 31 can be limited by the setting of the control slots 13.

[0058] In one embodiment of this application, such as Figure 4 As shown, the rear wheel abutment control component 4 includes a first hydraulic telescopic rod 40 and an abutment block 41.

[0059] The first hydraulic telescopic rod 40 is located at the bottom of the adjustment platform 1, and two abutment blocks 41 are respectively located on the extension shaft of the first hydraulic telescopic rod 40. The abutment blocks 41 slide against the corresponding drive blocks 31.

[0060] It should be noted that the abutment block 41 described in this example is an isosceles trapezoidal abutment block 41. By setting it to be isosceles, the abutment plate 30 can move at equal distances, thereby ensuring the correction of the rear wheel of the electric tricycle.

[0061] In one embodiment of this application, such as Figure 2 As shown, the lifting drive component 5 includes a base 50 and a second hydraulic telescopic rod 51.

[0062] The base 50 is set in a groove in the ground, one end of the second hydraulic telescopic rod 51 is rotatably connected to the base 50, and the other end of the second hydraulic telescopic rod 51 is connected to the adjustment table 1.

[0063] It should be noted that the first hydraulic telescopic rod 40, the second hydraulic telescopic rod 51 and the third hydraulic telescopic rod 72 described in this embodiment are all connected to a hydraulic system (not shown in the figure).

[0064] In one embodiment of this application, such as Figure 2 and Figure 3 As shown, the bottom of the front wheel platform 2 is provided with a first sliding wheel 20 and a second sliding wheel 21, and a third sliding wheel 22 is provided on one side of the front wheel platform 2. The first sliding wheel 20, the second sliding wheel 21 and the third sliding wheel 22 are rotatably connected to the first front wheel limiting channel 11, and the first sliding wheel 20, the second sliding wheel 21 and the third sliding wheel 22 are rotatably connected to the second front wheel limiting channel 700.

[0065] It is understandable that by setting the first sliding wheel 20 and the second sliding wheel 21 at the bottom of the front wheel platform 2, the stability of the movement of the front wheel platform 2 is ensured. By setting the third sliding wheel 22 on the side of the front wheel platform 2 (the side close to the center adjustment component 7), when the adjustment platform 1 is tilted upward, the front wheel platform 2 transitions from the first front wheel limiting channel 11 to the second front wheel limiting channel 700 through the third sliding wheel 22.

[0066] Specifically, in actual operation, the relevant operators push the electric tricycle onto the adjustment platform 1, with the front wheel of the electric tricycle located on the front wheel platform 2. The front wheel platform 2 limits the front wheel of the electric tricycle, and the two rear wheels of the electric tricycle are located on the adjustment plate.

[0067] The controller controls the first hydraulic telescopic rod 40 to extend and drive the abutment block 41 to move. The two sides of the abutment block 41 slide against the corresponding drive block 31, thereby driving the two abutment plates 30 to move at equal distances and abut against the corresponding rear wheels of the electric tricycle. If the electric tricycle is tilted, the equidistant movement of the rear wheel abutment limiter 3 will adjust the position of the two rear wheels of the electric tricycle through the abutment plates 30, thereby ensuring that the electric tricycle will not tilt during the inspection process.

[0068] The controller controls the lifting drive component 5, and the second hydraulic telescopic rod 51 raises the adjustment platform 1. Under the action of gravity, the electric tricycle moves towards the center adjustment component 7. During the movement, the front wheel platform 2 limits the front wheel of the electric tricycle, and the two abutment plates 30 limit the position of the two rear wheels of the electric tricycle, thereby continuously maintaining the stability of the electric tricycle and ensuring that the electric tricycle will not tilt during the inspection process.

[0069] The controller controls the retraction of the third hydraulic telescopic rod 72, causing the support frame 720 to move downwards, which in turn drives the rotating shaft 711 to move downwards, causing the two half-clamping plates 70 to move downwards. During the downward movement of the two half-clamping plates 70, they abut against the clamping plate control frame 73, thus forming a V-shape. During the formation of the V-shape, the front wheel of the electric tricycle is adjusted. After the adjustment is completed, the position of the front wheel is limited, the lifting drive component 5 returns to its initial position, the drive motor 80 runs and drives the torque limiter 81 to run. The torque limiter 81 drives the third hydraulic telescopic rod 72 to rotate, which in turn causes the two half-clamping plates 70 and the front wheel of the electric tricycle to steer. The angle sensor 82 monitors the front wheel and feeds the test results back to the controller. After the test is completed, the lifting drive component 5 drives the adjustment platform 1 downwards, and the electric tricycle returns to its initial position under the action of gravity, thus completing the wheel steering test.

[0070] In summary, the wheel steering testing device of this application embodiment is applicable to different types of electric tricycles and does not require manual adjustment or replacement by relevant personnel, thereby reducing the labor intensity of relevant personnel and improving the testing efficiency of wheel steering.
