Vehicle exterior swing value dynamic measuring device

Abstract

This utility model discloses a dynamic measuring device for the external sway value of a car. The key technical points are: it includes two mounting brackets, each with a water tank on its top surface, and a through hole on the top surface of the water tank; a top cover threaded into the through hole, with a water pump fixedly connected inside the top cover; a water suction pipe fixedly connected to the inlet of the water pump; and a fixing component located on one side of the mounting brackets. After the operator fixes the two mounting brackets to one side of the car, the water tanks are fixed to the top surface of the mounting brackets. The water pump is then started, and the pump can deliver water from the water tanks to the water delivery pipe via the suction pipe, allowing the water to flow to one side of the car, spraying water onto the front and rear of the vehicle. When the water reaches the outermost point of the rear of the vehicle and the point furthest from the steering center, as the vehicle moves, the water flows down the side of the vehicle and onto the ground, forming watermarks. The external sway value of the vehicle is measured by measuring the watermarks on the ground.

Description

Technical Field

[0001] This utility model relates to the field of automobile external swing measurement technology, specifically to a dynamic measurement device for automobile external swing value. Background Technology

[0002] Vehicle sway refers to the value by which any part of a car or car train extends beyond the vertical plane of the vehicle's outer side when transitioning from straight-line travel to circular motion in a turning lane. According to the "Method for Measuring Minimum Turning Diameter, Minimum Turning Lane Diameter and Sway Value of Automobiles" (GBT12540□2009), the sway value is measured by drawing a circle with a diameter of 25M on flat ground. Trajectory display devices are installed at the outermost point B at the rear of the vehicle and at the point A furthest from the turning center on the vehicle body. The vehicle then moves along a predetermined trajectory, and the sway value is measured based on the trajectory formed by the two trajectory display devices. The current experimental method involves three people working together: one drives the car, and the other two stand at the furthest points on the front and rear sides of the vehicle, respectively. When the vehicle starts and travels along the 25M circle, the other two people simultaneously pour water onto the furthest points on the front and rear sides of the vehicle body, creating watermarks on the ground. Measuring the watermarks at the furthest points on the front and rear sides reveals the vehicle's sway value.

[0003] However, the current device has the drawback that it requires three people to work together to complete the measurement. Holding the water container, the operator must spray water onto one side of the vehicle in sync with the vehicle speed, which poses a serious safety hazard. Over time, the operator is prone to fatigue, resulting in uneven water distribution on the vehicle. Therefore, a dynamic measurement device for vehicle sway value needs to be designed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a dynamic measurement device for automobile sway value to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A water pumping pipe is fixedly connected to the inlet of the water pump, and the outlet of the water pump is fixedly connected to the delivery pipe.

[0010] A fixing component is disposed on one side of the mounting bracket for securing the mounting bracket to the exterior of the vehicle.

[0011] Preferably, the fixing component includes:

[0012] Two mounting plates are fixedly connected to one side of the mounting frame, and an electromagnet is fixedly connected inside the mounting plate;

[0013] The mounting slot is formed on the top surface of the mounting frame, and the bottom surface of the water tank is fixedly connected to the mounting block, which is threadedly connected to the mounting slot.

[0014] Preferably, the top surface of the mounting bracket is provided with a fixing plate, the top surface of the fixing plate is provided with a pressing plate, and mounting holes are provided on one side of the pressing plate and one side of the fixing plate.

[0016] Preferably, the top surface of the fixing plate has two adjustment grooves, and a tension spring is fixedly connected inside the adjustment groove. The top end of the tension spring is fixedly connected to the bottom surface of the extrusion plate.

[0017] Preferably, the top surface of the mounting bracket has two threaded grooves, and the top surface of the fixing plate has a rotating hole. An adjusting rod is rotatably installed inside the rotating hole, and the adjusting rod is threadedly connected to the threaded grooves.

[0018] In the above technical solution, the vehicle outward swing value dynamic measurement device provided by this utility model has the following beneficial effects:

[0019] By setting up mounting brackets, after the workers fix two mounting brackets to one side of the car, they then fix the water tank to the top of the mounting brackets and start the water pump. The water pump can send water from the inside of the water tank to the inside of the water delivery pipe through the suction pipe, so that the water can flow to one side of the car and start spraying water on the front and rear of the car.

When the water flows to the outermost point of the rear of the car body and the point of the car body farthest from the steering center, as the vehicle moves, the water flows down the side of the car body to the ground to form water marks. The outward swing value of the vehicle is measured by measuring the water marks on the ground.

[0029] Specifically, the fixing components include two mounting plates 8, both of which are fixedly connected to one side of the mounting frame 1.

[0039] Work steps: 1. By setting up mounting bracket 1, after the staff fixes the two mounting brackets 1 to one side of the car, the water tank 2 is fixed to the top surface of the mounting bracket 1. The water pump 5 is started. The water pump 5 can send the water inside the water tank 2 to the inside of the water delivery pipe 7 through the water suction pipe 6, so that the water can flow to one side of the car and start spraying water on the front and rear of the car. When the water flows to the outermost point of the rear of the car body and the point of the car body farthest from the steering center, as the vehicle moves, the water flows down the side of the car body to the ground to form water marks.
