Based on the above embodiments, the technical problem that the present application is intended to solve is how to perform a test in a fully automatic manner under the condition that the safety of the central control screen of the automobile is ensured when the central control screen of the automobile is tested. For this reason, the rotatable setting of this application carousel 3 is on base 1, and support frame 2 sets up in one side of carousel 3, and speed adjusting mechanism 6 sets up on the upper portion of support frame 2, and the setting that speed adjusting mechanism 6 runs through is on carousel 3, and vibrating mechanism 5 is around the even setting of the axis of carousel 3 on the lateral wall of carousel 3. The placing box 7 is fixedly arranged at the upper part of the vibrating mechanism 5, and the protecting mechanism 4 is arranged inside the placing box 7. After the equipment is started, the rotary disc 3 is driven by the external driving device to rotate, so that the vibrating mechanism 5 fixedly arranged on the rotary disc 3 is driven to rotate together, and the placing box 7 fixedly arranged on the vibrating mechanism 5 also rotates together with the vibrating mechanism. Carousel 3 is arranged in carrying and places the dish, and the accuse screen is set up and is being placed box 7 back in when the car, and carousel 3 just can slowly drive and place box 7 rotatory, and speed adjusting mechanism 6 just can drive vibration mechanism 5 vibrations this moment, so just realized controlling the vibration detection of screen in the car to placing box 7. The working principle of the protection mechanism 4 is as follows, firstly, the automobile central control screen is placed into the placing box 7 on one side of the turntable 3 through the mechanical arm, and when the automobile central control screen is in contact with the trigger block 4a, the automobile central control screen is not clamped. When the automobile central control screen finishes clamping, the bottom of the automobile central control screen completely presses the trigger block 4 a. The trigger block 4a moves in the depth direction of the groove 4c under the depression of the screen in the automobile. At this time, the trigger block 4a will press the first slider 4d to both sides, so that the first slider 4d moves towards the end far away from the trigger block 4a along the length direction of the first sliding slot 4b, and at this time, the first spring 4e will be compressed by the first slider 4 d. Because pushing component 4f and first slider 4d interconnect, so when first slider 4d takes place to slide, pushing component 4f also can take place to remove, and then can make and push component 4f interconnect's protection subassembly 4g promoted, the upper portion terminal surface of protection subassembly 4g all the time with place the upper portion terminal surface coplane of box 7. When the first sliding block 4d slides, the pushing component 4f can drive the protecting component 4g to slide on the upper part of the placing box 7. After the control screen is put into and is placed box 7 and contact each other with trigger block 4a in the car promptly, trigger block 4a is pressed gradually this moment, and first slider 4d can be promoted gradually, and it also can slowly drive protection component 4g and slide closure gradually to promote subassembly 4f this moment. So when controlling the screen and being put into completely and placing in the box 7 in the car, protection subassembly 4g can be closed completely, and locking reset assembly 4h can start simultaneously, and locking reset assembly 4h can trigger block 4a locking for protection subassembly 4g can not open automatically when the vibration. Speed adjusting mechanism 6 just can drive 5 vibrations of vibration mechanism after that, when 6 drive vibration mechanisms 5 of speed adjusting mechanism shake, carousel 3 also can slowly drive and place 7 rotations of box, after carousel 3 drives and places 7 rotatory 180 degrees of box, the vibration test ended this moment, locking reset assembly 4h loosens and triggers piece 4a, and the control screen slowly takes out in the automobile that the box 7 will be placed to the arm that sets up in 3 one side of carousel. The trigger block 4a returns to the initial position, and the first slider 4d returns to the initial position under the action of the first spring 4e, and the protection member 4g is also opened. Therefore, the control screen in the automobile can be completely taken out. Therefore, when the automobile central control screen is tested, the safety of the automobile central control screen can be ensured, and the technical requirement of full-automatic testing can be met.

When the trigger block 4a is pressed by the control panel of the vehicle, the trigger block 4a presses the first sliding block 4d to slide along the length direction of the first sliding slot 4b, so that the connecting rod 4f1 hinged with the first sliding block 4d rotates around the axis of the fixed shaft 4f 2. At this time, the link 4f1 will drive the extension sleeve 4f3 to rotate. Since the distance between the lower part of the protection component 4g and the bottom of the placing box 7 is constant, when the connecting rod 4f1 rotates around the fixed shaft 4f2, the linear distance between the hinge joint of the connecting rod 4f1 and the first sliding block 4d and the hinge joint of the extension rod 4f4 and the protection component 4g changes, and the change of the distance can be compensated by the extension rod 4f4 and the extension sleeve 4f 3. When the distance becomes shorter, the extension rod 4f4 will slide into the extension sleeve 4f 3; when this distance becomes longer, the extension rod 4f4 will gradually slide out of the extension sleeve 4f 3. Therefore, the technical requirement that the pushing component 4f can drive the protection component 4g to slide is met.

Therefore, the length direction of the second sliding groove 4g2 is collinear with the length direction of the placing box 7, the upper end face of the baffle 4g1 is coplanar with the upper end face of the placing box 7, one end of the extending rod 4f4, which is far away from the extending sleeve 4f3, is hinged to one end of the baffle 4g1, and when the extending rod 4f4 moves, the baffle 4g1 can slide along the length direction of the second sliding groove 4g2 under the driving of the extending rod 4f 4. The protection member 4g3 is preferably made of flexible material, and when the automobile central control screen placed in the box 7 falls off due to vibration, the automobile central control screen is shielded by the baffle plate 4g1, and the protection member 4g3 arranged at the lower part of the baffle plate 4g1 can prevent the automobile central control screen from colliding with the baffle plate 4g1 after being thrown out, and then the automobile central control screen is damaged. Therefore, the technical requirement that the protective component 4g can prevent the control screen in the automobile from flying out of the placing box 7 is met.

Further, as shown in fig. 10:

the lock return assembly 4h includes a second spring 4h1 and a first magnet 4h 2; the first magnet 4h2 is fixedly arranged at the bottom of the groove 4 c; a second gap is reserved between the trigger block 4a and the bottom of the groove 4c, and a second spring 4h1 is arranged on the second gap.

Based on the above embodiment, the technical problem to be solved by the present application is how to implement the locking and unlocking reset of the trigger block 4a by the locking reset component 4 h. For this purpose, the two ends of the second spring 4h1 are respectively and fixedly connected with the triggering block 4a and the bottom of the groove 4c, and the first magnet 4h2 is preferably an electromagnet. After the automobile central control panel is placed in the placing box 7, the triggering block 4a at the moment can be pressed by the automobile central control panel, and after the protection component 4g is completely closed, the second spring 4h1 is in a compressed state at the moment. The first magnet 4h2 is energized, and since the trigger block 4a is made of magnetic material, the trigger block 4a is tightly attached to the first magnet 4h2 after the first magnet 4h2 is energized, so as to ensure that the protection component 4g will not automatically open during the vibration test. After the test is finished, the first magnet 4h2 is powered off, the trigger block 4a is restored to the initial position by the second spring 4h1, and the mechanical arm arranged on one side of the turntable 3 can take out the automobile central control screen. This realizes the function that the lock-reset component 4h can lock and unlock the trigger block 4a for resetting.

Therefore, the ejector 5b is of a semi-cylindrical structure, and the top of the vibrating rod 5a is fixedly connected with the top of the placing box 7. When the turntable 3 rotates, the housing 5c disposed on the side wall of the turntable 3 rotates along with the turntable. However, since the rotation speed of the turntable 3 is slow, an excessive centrifugal force is not applied to the set cassette 7. After the control screen is placed in the placing box 7 in the automobile, the speed regulating mechanism 6 starts to be started, the speed regulating mechanism 6 jacks the jacking piece 5b along the length direction of the vibrating rod 5a at intervals, and after the jacking piece 5b is jacked up by the speed regulating mechanism 6, the vibrating rod 5a slides along the height direction of the shell 5 c. Under the drive of vibrating arm 5a, the dog 5f of setting on vibrating arm 5a also can be driven, will make dog 5f and hold the distance between the chamber 5e bottom grow gradually like this, and then make third spring 5d driven tensile. When the speed regulation mechanism 6 passes through the ejector 5b, and the ejector 5b is not pushed by the speed regulation mechanism 6 any more, the vibrating rod 5a can restore to the initial position under the action of gravity, and when falling, the third spring 5d is arranged in the accommodating cavity 5e, so that the box 7 can be guaranteed to be placed and cannot collide with the upper part of the shell 5c when falling.

Based on the above embodiments, the technical problem to be solved by the present application is how to implement the vibration speed regulation function of the speed regulation mechanism 6. For this purpose, the rotary drive 6a is preferably a servomotor and the linear drive 6h is preferably a linear cylinder. When the linear driver 6h is in the retracted state, the rotary driver 6a starts to rotate, the rotating shaft 6c disposed at the output end of the rotary driver 6a is driven to rotate, so that the first protrusion 6b disposed on the rotating shaft 6c is driven to rotate, the first protrusion 6b is of a cam structure, and thus the vibrating mechanism 5 can be jacked up. If the vibration speed needs to be increased, the linear driver 6h needs to be extended out, and under the driving of the linear driver 6h, the rotary driver 6a can push the rotating shaft 6c to slowly move towards the side of the rotary disc 3 far away from the rotary driver 6a, so that the first speed regulating assembly 6d and the second speed regulating assembly 6e can be activated, and the purpose of speed regulation can be achieved. Thus, the vibration speed regulation function of the speed regulation mechanism 6 is realized.

Based on the above-described embodiment, the technical problem to be solved by the present application is how to further accelerate the governor mechanism 6 by the second governor assembly 6 e. Therefore, after the first speed regulating assembly 6d is activated, if the speed needs to be increased, the output end of the linear driver 6h continues to extend, at this time, one end of the rotating shaft 6c, which is far away from the rotary driver 6a, is in contact with the second clamping block 6e4, the second clamping block 6e4 is pushed by the rotating shaft 6c to gradually move towards the second clamping groove 6e3, and when the second clamping block 6e4 is clamped into the second clamping groove 6e3, the rotary driver 6a drives the rotating shaft 6c to rotate at this time. When the speed is reduced, the output end of the linear driver 6h is retracted, and the second clamping block 6e4 is disengaged from the second clamping groove 6e 3.

Further, as shown in fig. 5-6:

positioning assembly 6g includes signal transmitter 6g1 and signal receiver 6g 2; the signal receivers 6g2 are uniformly arranged on the side wall of the rotating disk 3 around the axis of the rotating shaft 6 c; the signal emitters 6g1 are disposed on the first bump 6b, the second bump 6d5, and the third bump 6e2, respectively.

Based on the above embodiments, the technical problem to be solved by the present application is how to implement the positioning function of the positioning component 6 g. Therefore, three signal transmitters 6g1 are provided, the signal receivers 6g2 correspond to the signal transmitters 6g1 one by one, and when all the signal receivers 6g2 receive the signals transmitted by the signal transmitters 6g1, it is indicated that positioning is completed.

Further, as shown in fig. 10:

the speed regulating mechanism 6 further includes a second magnet 6 f; the second magnet 6f is fixedly disposed at an upper portion of the accommodating chamber 5 e.

Based on the above embodiments, the technical problem to be solved by the present application is how to make the speed adjusting mechanism 6 shift gears better. For this reason, the second magnet 6f of the present application is preferably an electromagnet. When the speed adjusting mechanism 6 is used for adjusting the speed, in order to prevent the ejector 5b from influencing the speed adjusting mechanism 6, the second magnet 6f is electrified, the second magnet 6f can attract the stop block 5f, and thus the vibrating piece can drive the ejector 5b to lift.
