Description

Technical Field

[0001] This utility model belongs to the field of motorcycle testing and relates to a device for measuring the opening of a motorcycle throttle lever. Background Technology

[0002] The newly promulgated (EU) No 134 / 2014 (ECE R41.05) European noise standard requires additional noise (RD-ASEP) for Class L3 motorcycles with a PMR>50. In addition to the test procedure for measuring noise under full acceleration, it adds the requirement to test the noise sound pressure level under multiple operating conditions (throttle opening: fully open, partially open, half open, etc.) when the vehicle is driving on actual roads; and to record the actual throttle opening under various operating conditions. In actual test implementation, problems such as reference benchmarks, operational errors, and unpredictable vehicle conditions lead to low accuracy and poor reproducibility of test data, a lot of repetitive work in test operations, and low work efficiency. Moreover, the inability to record the actual throttle opening state brings great difficulties to the actual conduct of the test.

[0003] According to the requirements of the European noise standard, the current testing is carried out by manually marking or by repeatedly testing based on the experience and feelings of drivers. The test data is extracted from a large number of data samples, which is cumbersome, involves a large number of data samples, and has low work efficiency. It requires a lot of manpower and time.

[0033] like Figure 1 As shown, this is the motorcycle throttle opening measuring device described in this embodiment. It assists the driver in operating the test vehicle and can repeatedly measure under the same opening conditions to ensure the consistency and accuracy of the test, avoiding repeated testing and wasting manpower and resources.

[0034] The motorcycle throttle grip opening measuring device includes an outer rotor 1 of the throttle grip, a metal tube 2 of the handlebar, an outer rotor 4 of the angle sensor, an inner rotor 5 of the angle sensor, an upper retainer 6, a lower retainer 7, a deformable rubber 16, a signal cable 18, a VBOX vehicle road test instrument 19, a monitoring instrument 20, and a bracket 21.

[0035] Before installation, remove the original balance weights to expose the handlebar metal tube 2. The throttle throttle outer rotor 1 and the handlebar metal tube 2 are a complete set and installed on the motorcycle. The handlebar metal tube 2 is fixedly connected to the motorcycle and serves as a fixed support. The handlebar metal tube 2 remains fixed and does not rotate. The throttle throttle outer rotor 1 is rotatably connected to the motorcycle. The throttle throttle outer rotor 1 is fitted over the outside of the handlebar metal tube 2 and rotates around the handlebar metal tube 2.

[0036] like Figure 2 As shown, both the upper retainer 6 and the lower retainer 7 are semi-circular structures. The inner walls of the upper retainer 6 and the lower retainer 7 are tightly attached to the circumferential surface of the free end of the outer rotor 1 of the throttle handle, as shown. Figure 3 As shown, the upper retainer 6 and the lower retainer 7 are connected at both ends by the first screw 8 and locked with the wing nut 10. The bottom of the two first screws 8 are rotatably connected to the two ends of the lower retainer 7 by the first pin 9. The first screw 8 can rotate around the first pin 9 in a longitudinal 180° plane. The upper retainer 6 has a fixing groove at both ends. The top of the first screw 8 is located in the fixing groove. The wing nut 10 is installed on the first screw 8 and tightened at the end face of the fixing groove for locking. The outer rotor 1 of the throttle handle is connected to the upper retainer 6 and the lower retainer 7, so that the upper retainer 6 and the lower retainer 7 can rotate with the outer rotor 1 of the throttle handle.

[0037] like Figure 2 and Figure 4As shown, an angle sensor is installed at the free end of the handlebar metal tube 2. The angle sensor includes an outer rotor 4 and an inner rotor 5. The inner rotor 5 is fixedly connected to the free end of the handlebar metal tube 2. The outer rotor 4 is sleeved on the inner rotor 5 and rotatably connected to it. A U-shaped groove 13 is provided on the outer rotor 4, and a pin hole 3 is provided at the longitudinal center of the U-shaped groove 13. A connecting groove 12 is provided on the top of the upper fixing device 6. The end of the second screw 15 passes through the pin hole 3 via a second pin 14. The second screw 15 rotates... The second screw 15 is dynamically connected in the U-shaped groove 13. The front end of the second screw 15 is located in the connecting groove 12. The second screw 15 can be rotated 180° laterally through the matching second pin 14. The front end of the second screw 15 can be placed in the connecting groove 12, so that the outer rotor 4 of the angle sensor rotates synchronously with the outer rotor 1 of the throttle handle through the upper fixing device 6. The inner rotor 5 of the angle sensor determines the rotation angle of the outer rotor 1 of the throttle handle based on the rotation angle of the outer rotor 4 of the angle sensor. The front end of the second screw 15 can also be removed from the connecting groove 12, so that the outer rotor 4 of the angle sensor and the outer rotor 1 of the throttle handle do not rotate synchronously.

[0038] like Figure 5 and Figure 6 As shown, the specific method of fixing the inner rotor 5 of the angle sensor to the free end of the handlebar metal tube 2 is as follows: The inner rotor 5 of the angle sensor has a screw hole that is matched with the fixing bolt 11. The fixing bolt 11 passes through the inner rotor 5 of the angle sensor and is located inside the handlebar metal tube 2. Two nuts 17 are provided on the fixing bolt 11, and a deformable rubber 16 is provided between the two nuts 17. It is installed in the handlebar metal tube 2. The nut 17 located on the inner side of the handlebar metal tube 2 is fixedly connected to the fixing bolt 11, and the nut 17 located on the outer side of the handlebar metal tube 2 is threadedly connected to the fixing bolt 11. By rotating the fixing bolt 11 towards the outer side of the handlebar metal tube 2, the nut 17 located on the inner side of the handlebar metal tube 2 is always fixed. The nut 17 located on the outer side of the handlebar metal tube 2 can only be squeezed against the deformable rubber 16 due to the limitation of the inner rotor 5 of the angle sensor, so that the inner wall of the handlebar metal tube 2 cooperates with the radially expanding deformable rubber 16 to ensure reliable fixation.

[0039] like Figure 1 As shown, the outer rotor 4 of the angle sensor has a signal line 18 connected to the monitoring instrument 20. The monitoring instrument 20 includes a housing with a liquid crystal display, a power input terminal, and a signal receiving terminal. The signal receiving terminal is connected to the outer rotor 4 of the angle sensor via the signal line 18. The monitoring instrument 20 can indicate the opening percentage value. The monitoring instrument is mounted on a bracket 21, which is fixed to the vehicle rearview mirror fixing bolts. The monitoring instrument 20 is connected to a 12V DC power supply (using the vehicle's power supply) and a VBOX vehicle road test instrument 19.

[0040] Because the throttle opening angle is inconsistent for each vehicle, the monitoring instruments are equipped with automatic zeroing and one-click calibration functions for the turning angle (opening angle), which can meet the needs of 99% of throttle controllers.

[0041] The monitoring instrument 20 is model HXDSBOXAI under the oneBusi brand.

[0042] The process of measuring the opening of the motorcycle throttle lever using the above-mentioned motorcycle throttle lever opening measuring device is as follows:

[0043] The front end of the second screw 15 can be placed in the connecting groove 12. The test driver rotates the outer rotor 1 of the throttle handle, so that the outer rotor 4 of the angle sensor rotates synchronously with the outer rotor 1 of the throttle handle through the upper fixing device 6. The outer rotor 4 of the angle sensor transmits data to the monitoring instrument 20 through the signal line 18. At the same time, the monitoring instrument 20 indicates the throttle opening percentage value. The driver can perform experimental operations according to the opening percentage value displayed by the monitoring instrument 20 and refer to the stable opening state. The data is output synchronously and recorded in the database of the VBOX vehicle road test instrument 19 for analysis and comparison.
