With reference to figure 7 and Fig. 8, the work of the rear cover durability test device of an embodiment according to the present utility model is disclosed
Process schematic, wherein Fig. 7 disclose the opening process of rear cover, and Fig. 8 discloses the closing process of rear cover.
Upon start before lid endurance test, need first to carry out following preparation：
1) according to the difference of different automobile types rear cover opening angle, the angle of inclination of the sliding rail in straight line executing mechanism is carried out
It adjusts, to ensure that rear cover is not interferenceed during the motion with the sliding block generation in straight line executing mechanism.The angle of inclination of sliding rail
It is adjusted by angle adjusting mechanism：Unclamp hexagon socket head cap screw between sliding bar and holder and bedframe and sliding rail it
Between hexagon socket head cap screw.Sliding bar is set to be moved forward and backward in the horizontal direction, so as to adjust the inclination of sliding rail in straight line executing mechanism
Angle can refer to state shown in Fig. 5 a and Fig. 5 b.

Position is stablized during testing, and will not be moved.
The durable examination of closing of tens thousand of cycles of rear cover can be rapidly completed in the rear cover durability test device of the utility model
It tests.Each cycle is opened comprising rear cover closes two processes with rear cover.
Fig. 7 discloses the opening process of rear cover, and rear cover opening process includes several following steps：
Initial position：When sliding block is in initial position A, traction element needs slightly to tighten.The step for be in order to follow-up
After rear cover unlock, servo motor can be promptly by the pre- opening angle of one very little of rear cover pull-up.
Rear cover, which is powered, to be unlocked：It is unlocked to back cover lock by controlling the break-make of relay and 12V power supplys in electrical cabinet.When
When operation is to rear cover energization unlocked step, relay is connected, back cover lock unlock.
Servo motor driving sliding block rising is moved to position B：Rear cover is powered after unlock, and servo motor drives sliding block will at once
One angle of rear cover pull-up very little, sliding block are run to position B.Position B will ensure that back cover lock is completely disengaged with rear cover lock.If
Back cover lock failure, or because other reasons such as 12V power supplys are burnt out, rear cover unlock failure, servo motor is because can not be upward by rear cover
Be pulled to position B and lead to motor rotation blockage, at this time motor output torque moment increase, pulling force sensor can collected value of thrust surpass
Mark alarms and stops experiment.
Servo motor driving sliding block rising is moved to position C：If rear cover unlock is normal, sliding block trouble-free operation to position B
Afterwards, rear cover is continued up drawing by servo motor driving sliding block, and sliding block is run to the C of position, and rear cover gas spring crosses lower dead center, rear cover
It opens completely, judges whether rear cover is opened completely close to switching on-off by opening.
Fig. 8 discloses the closing process of rear cover, and rear cover closing process includes several following steps：
Pre-shutdown：Servo motor drives sliding block to be moved to position D from position C declines：After rear cover is opened completely, servo electricity
Machine inverts, and drives transmission belt reverse movement, to drive sliding block that rear cover is slowly pulled down, this step is known as pre-shutdown.It is pre- to close
The excessive velocities closed can cause excessive to the metal plate of rear cover licence plate frame region and the moment impact of rear cover gas spring.Therefore, this
One step servo motor slowly will start to walk and accelerate.
It closes：After pre-shutdown, servo motor is disposably shut rear cover with faster rotating speed by traction element, this
When sliding block position, from position, D returns to position A.The closing velocity of different automobile types requires difference, the rear cover of the utility model resistance to
Long property experimental rig can adjust closing velocity according to different requirements in the range of 0.5m/s-3m/s.
When rear cover closing velocity is too small, when not reaching test requirements document, there are following several methods for adjusting closing velocity：
Directly increase servo motor in the speed for closing step.Such method is typically to give tacit consent to the acceleration of current servo motor
Degree is enough, and sliding block is enough to the acceleration distance of position A from position D.
Adjusting the height of sliding block in rear cover pre-shutdown step so that sliding block increases from position D to the acceleration distance of position A,
To which final speed increases.
Increasing servo motor in the deceleration for closing step so that sliding block increases from position D to the acceleration time of position A,
To which most total speed increases.
The total Test device of the rear cover durability test apparatus of the utility model is arranged in the outside of automobile, easy for installation,
There is no any change and destruction to vehicle.The rear cover durability test device is driven using servo motor, and cooperation straight line executes machine
Structure acts.Straight line executing mechanism is integrated with action of uncapping and is acted with lid is closed, while pulling force sensor is added, rear cover is opened and closed
Pulling force during closing is monitored.The rear cover durability test apparatus of the utility model overcomes prior art preparatory period and operation
The disadvantage of period length using servo motor as driving element there is pulling force monitoring function, the device to open and close rear cover
Action is succinct, efficient, and it is durable 30,000 rear covers can be completed in one week.The device is easy for installation, and the speed of service and precision
It is not influenced by high/low temperature.
