Description

Vehicle-mounted driving auxiliary module performance detection system

Technical Field

The invention relates to the technical field of vehicle-mounted accessory detection, in particular to a vehicle-mounted driving auxiliary module performance detection system.

Background

An automobile generally consists of four basic parts, namely an engine, a chassis, a vehicle body and electric equipment, wherein the electric equipment of the automobile comprises a power supply system, a starting system, an ignition system, a lighting device, a signal device, an instrument and other various electronic equipment, and the electronic equipment comprises an engine control system, a transmission control system, an anti-lock braking system, a vehicle-mounted driving auxiliary module and the like.

The driving assistance module of the automobile is based on the technical means such as an on-vehicle sensor, a communication technology, an AI algorithm and the like, and generally the driving assistance module can be divided into the following forms: lane keeping assist system, adaptive cruise control system, intelligent parking system and blind spot monitoring system; the driving assistance module can enable a driver to drive the vehicle more safely, conveniently and comfortably, and meanwhile, the risk of traffic accidents of the vehicle can be greatly reduced.

Because the car is in actual driving in-process, often passe through the highway section of jolting, consequently drive auxiliary module receives the circumstances of vibrations for a long time and takes place to damage easily, and drive auxiliary module's last spliced terminal appears becoming flexible and then lead to its unable normal use easily, consequently, in order to improve drive auxiliary module's result of use, after its production is accomplished, need carry out shock resistance to it and detect to be convenient for carry out corresponding optimization to it according to drive auxiliary module's testing result.

However, when the existing automotive electronic equipment is detected, some problems usually exist, along with development of technology, a person skilled in the relevant field also optimizes a detection mode of the electronic equipment in a large amount, and in order to perform more accurate comparison, for example, a technical scheme for testing automotive electronic parts is disclosed in chinese patent with publication number CN215004162U, which specifically discloses an automotive part vibration testing device, comprising a box body, wherein a switch door is arranged on a rear side wall of the box body, and a placing plate, an elastic mechanism, a vibration driving mechanism, a lifting assembly and a driving assembly for placing automotive electronic parts are arranged in the box body.

When the automobile electronic component mounting device is used, firstly, an automobile electronic component to be detected is fixedly placed on a placing plate, and then the lifting rod is lifted and pressed through the vertical plate to lift in the mounting shell, so that the vibration force of the elastic mechanism on the automobile electronic component is regulated; when the shock resistance of the automobile electronic part is detected, the driving rod, the first connecting rod and the second connecting rod are driven by the driving motor to integrally rotate and drive the placing plate to lift, so that the shock test of the electronic part to be detected is realized.

However, the above-mentioned vibration testing device for automobile parts has some disadvantages in the actual use process:

1. Because the electronic parts of the automobile are relatively fixed with the automobile in the actual use process, the electronic parts shake with the automobile in the same amplitude when the automobile jolts, so that the electronic parts cannot be collided; the electronic part is only placed on the placing plate and is not fixed, so that the placing plate is easy to collide with the top of the placing plate in the lifting process, the electronic part is easy to damage in the testing process, and the anti-seismic performance of the electronic part cannot be accurately detected in the testing mode.

2. Because the road sections with different jolting degrees can be passed through in the actual driving process of the automobile, the vibration effects suffered by the electronic parts in the automobile are also different, so that the vibration performance of the electronic parts in the actual driving process of the automobile can not be simulated only by lifting the placing plate when the electronic parts are subjected to vibration test, and the use effect of the electronic parts is further affected.

3. In addition, the electronic equipment in the automobile is in a working state during running, so that the electronic equipment is easy to burn, further the electronic parts are heated, the heated electronic parts can possibly have conditions of operation blocking, circuit damage and the like, and the vibration testing device for the automobile parts cannot test the high temperature resistance of the electronic parts, so that the high temperature resistance of the electronic parts in the actual use process cannot be ensured.

Referring to fig. 1 and 3, since the driving assistance module is relatively fixed with the vehicle during actual use, when the vehicle passes through a bumpy road section, the driving assistance module has the same vibration amplitude as the vehicle, so that the detection cylinder 3 needs to be relatively fixed with the driving assistance module during vibration; based on this, provided in the specific embodiment of this scheme is used for the fixed extrusion fixed part 4 of driving assistance module, specifically, extrusion fixed part 4 is including setting up at the inside ladder brace table 41 of detecting section of thick bamboo 3, detects the inside two baffles 42 that are provided with of section of thick bamboo 3, makes the inside cavity 43 that is used for placing driving assistance module of detecting section of thick bamboo 3 evenly separate into three through baffle 42, all is provided with two ladder brace tables 41 along the width direction symmetry of detecting section of thick bamboo 3 in every cavity 43.

Further, in this embodiment, openings for taking and placing driving assistance modules are formed on both side walls of the detection cylinder 3 in the width direction, supporting spring rods 44 are mounted on both sides of the upper end of the detection cylinder 3 in the width direction of the baffle plate 42, the upper ends of the supporting spring rods 44 are connected with a lower pressing plate 45 together, an extrusion piece 47 is mounted below the lower pressing plate 45 through an executing mechanism 46, and a heat preservation mechanism 48 is arranged among the lower pressing plate 45, the baffle plate 42 and the workbench 1; the support spring rod 44 always applies an upward supporting force to the lower pressure plate 45 so that the lower pressure plate 45, and the pressing piece 47 are positioned at the highest position in the initial state, in order to place the driving assistance module in the cavity 43.

In the specific implementation process, after the driving auxiliary modules are respectively placed at the upper ends of the step support tables 41 in different cavities 43, the lower pressing plate 45 is controlled to move downwards by the execution mechanism 46, and the lower pressing plate 45 drives the extrusion piece 47 to move downwards and press the upper ends of the driving auxiliary modules; with this through the extrusion 47 and ladder brace table 41 can extrude simultaneously the fixed upper and lower both sides of driving assistance module for relatively fixed between driving assistance module and the detection section of thick bamboo 3, in order to detect driving assistance module's shock resistance, and can ensure driving assistance module's stability, prevent that driving assistance module from bumping with the external world and damaging in the testing process.

Referring to fig. 4 and 5, in order to facilitate controlling the lower pressure plate 45 and the extrusion piece 47 to move downwards, corresponding actuating mechanisms 46 are provided in this embodiment, specifically, the actuating mechanisms 46 include a pressing rod 461, the upper end of the lower pressure plate 45 is symmetrically and movably connected with two pressing rods 461 located above the baffle plate 42 along the length direction thereof, the middle part of the outer wall of the pressing rod 461 is provided with threads, the middle part of the pressing rod 461 is sleeved with an actuating plate 462 located above the lower pressure plate 45 in a threaded connection manner, the outer wall of the pressing rod 461 and located above the actuating plate 462 are fixedly sleeved with an annular fixing plate 463, and a telescopic spring 464 is installed between the annular fixing plate 463 and the actuating plate 462; since the annular fixing plate 463 is in a fixed state, the telescopic spring 464 always applies a contraction force for upward movement to the execution plate 462, so that friction force between the execution plate 462 and the screw threads of the outer wall of the pressing rod 461 can be increased, and further the execution plate 462 is limited, preventing the execution plate 462 from moving up and down at will along the axis of the pressing rod 461.

In the specific implementation process, the pressing rod 461 is controlled to move downwards, and the pressing rod 461 applies downward pushing force to the lower pressing plate 45 through the execution plate 462, so that the lower pressing plate 45 drives the pressing piece 47 to synchronously move and abut against the upper side of the driving auxiliary module, thereby facilitating the control of the pressing piece 47 to move downwards rapidly; in addition, since the heights of the driving assistance modules of different models are also different, in order to ensure that the pressing member 47 presses and fixes the driving assistance modules better, it is necessary to control the distance that the pressing member 47 moves downward; specifically, the actuating plate 462 is rotated, the actuating plate 462 moves up and down along the axis of the pressing rod 461, and since the distance by which the lower pressure plate 45 and the pressing piece 47 move down is equal to the distance between the actuating plate 462 and the lower pressure plate 45, the distance by which the pressing piece 47 moves down can be controlled by adjusting the distance between the actuating plate 462 and the lower pressure plate 45; therefore, the driving auxiliary modules with different heights can be pressed and fixed conveniently, and the adaptability is high.

Because the inner wall of the circular groove 467 is provided with a plurality of annular grooves 469, when the extrusion 47 moves down to different positions, the positioning block 466 can be screwed into the corresponding annular groove 469 according to the position of the extrusion 47, so that the driving auxiliary modules with different heights can be extruded and fixed.
