As shown in fig. 1-3, the present invention relates to a device 10 for testing high temperature aging of a backlight source of a mobile phone, comprising: the aging room 20, the door 30, the heating device 50, the clamping and conveying device 60 and the exhaust heat dissipation device 70. The door body 30 is hinged with the aging room 20; the clamping and transmitting device 60 is arranged in the aging room 20 and clamps and transmits the backlight source of the mobile phone; the heating device 50 is arranged on the top of the aging room 20 and heats the backlight source of the mobile phone on the clamping and conveying device 60.
As shown in fig. 3, 5 and 6, the exhaust heat dissipation device 70 is disposed on the side wall of the aging room 20. The exhaust heat dissipation device 70 includes an exhaust fan 710 and an exhaust duct 720. The air inlet 721 of the air exhausting duct 720 extends into the aging room 20, and the air outlet (not shown) extends out of the aging room 20. The air blower 710 is disposed in the aging room 20 and connected to an air inlet 721 of the air exhaust duct 720. In the present embodiment, the exhaust duct 720 is an L-shaped elbow. The design of the L-shaped elbow of the exhaust duct 720 prevents direct exhaust when the exhaust fan 710 exhausts the high-temperature gas in the aging room 20, thereby preventing the local temperature reduction from being too fast and affecting the test effect.
As shown in fig. 4, in the present embodiment, the clamping transport device 60 includes: the device comprises a fixed base 610, a sliding base 620, a horizontal traversing assembly (not shown), a longitudinal vertical moving assembly 640 and a clamping assembly 650. The fixed base 610 is arranged in the aging room 20, the horizontal traversing assembly is in driving connection with the sliding base 620, and the sliding base 620 is arranged on the fixed base 610 in a sliding manner; the longitudinal vertical moving component 640 is connected with the sliding base 620, and the longitudinal vertical moving component 640 is in driving connection with the clamping component 650.
As shown in fig. 4, in the present embodiment, the fixed base 610 is provided with a guide rail 611, and the sliding base 620 is provided with a guide groove (not shown), which is matched with the guide rail 611.
As shown in fig. 4, in the present embodiment, the clamping assembly 650 includes: a support plate 651, a clamp 652 and a flip driver 653. The overturning driver 653 is in driving connection with the longitudinal vertical moving assembly 640; the support plate 651 is drivingly connected to the flip driver 653; the clamping member 652 is provided on the support plate 651.
When the high-temperature aging test is carried out on the mobile phone backlight source, the mobile phone backlight source is placed on the supporting plate 651, and the clamping piece 652 clamps the mobile phone backlight source; then the horizontal traverse assembly drives the sliding base 620 to move along the guide rail 611 to the right below the heating device 50; the longitudinal vertical moving component 640 drives the clamping component 650 to vertically move along the longitudinal direction, so as to adjust the vertical distance between the backlight source of the mobile phone and the heating device 50;
in addition, the turning driver 653 can turn the backlight source of the mobile phone, so as to change the heating surface of the backlight source of the mobile phone directly facing the heating device 50, thereby adjusting the heating angle of the backlight source of the mobile phone;
in addition, when the temperature in the aging room 20 is too high during the process of heating the backlight source of the mobile phone by the heating device 50, the exhaust fan 710 of the exhaust heat dissipation device 70 is activated. At this time, the exhaust fan 710 exhausts the high-temperature gas in the aging room 20 through the exhaust duct 720, so as to achieve a cooling effect, ensure that the temperature in the aging room 20 is stably maintained within a preset temperature range (i.e., improve the control accuracy of the aging temperature), and further improve the accuracy of the high-temperature aging test result of the mobile phone backlight source.
In the process of heating the mobile phone backlight source by the heating device 50, the door 30 is opened to avoid misoperation of workers, so that normal work of high-temperature aging test is avoided, burn accidents are avoided, and the door 30 needs to be locked.
The door 30 of the existing mobile phone backlight high-temperature aging test device 10 is mainly opened by a key, one key corresponds to one door lock, and once the key is lost, the door 30 cannot be normally opened. In addition, the door 30 of some conventional mobile phone backlight high-temperature aging test devices 10 has no locking mechanism, so that some non-working personnel can open and close the door 30 at will, which affects the high-temperature aging test of the mobile phone backlight and is easy to cause burn accidents.
As shown in fig. 1 and fig. 7, in view of this, the mobile phone backlight high-temperature aging testing apparatus 10 of the present invention further includes a locking device 40 on the door 30. The mobile phone backlight high-temperature aging test equipment 10 of the invention replaces the traditional key unlocking mode, and the door body 30 can be opened or closed only by mastering the normal using method.
As shown in fig. 7, in detail, the mobile phone backlight high-temperature aging test equipment 10 of the present invention further includes a locking device 40 disposed on the door 30. As shown in fig. 8, the locking device 40 includes: an opening-closing switching mechanism 100, a push type driving mechanism 200 and a telescopic lock pin 300. The door body 20 is formed with a locking groove (not shown) engaged with the retractable locking pin 300, and the push type driving mechanism 200 drives the retractable locking pin 300 to reciprocate through the opening/closing switching mechanism 100, so that the retractable locking pin 300 enters or leaves the locking groove.
It can be understood that when the retractable latch 300 enters the lock slot, locking is achieved, so that the door 30 cannot be opened from the aging room 20; when the telescopic lock pin 300 is disengaged from the lock groove, unlocking is realized, so that the door body 30 can be opened from the aging room 20.
As shown in fig. 8, specifically, the locking device 40 further includes a base 400, and the base 400 is fixed to the door 30.
Referring to fig. 8, 9 and 10, the opening/closing switching mechanism 100 includes: a conversion gear 110, a lifting type locking straight tooth 120 and a lifting type unlocking straight tooth 130. The conversion gear 110 is rotatably disposed on the base 400, and the lifting locking spur 120 and the lifting unlocking spur 130 are engaged with both sides of the conversion gear 110. It can be understood that, during the rotation of the conversion gear 110, the lifting locking spur 120 and the lifting unlocking spur 130 engaged therewith will perform a corresponding lifting movement. For example, when the shift gear 110 rotates clockwise, the lifting and lowering type locking spur 120 engaged therewith moves downward, and the lifting and lowering type unlocking spur 130 engaged therewith moves upward. Similarly, when the conversion gear 110 rotates counterclockwise, the lifting locking spur 120 engaged therewith moves upward, and the lifting unlocking spur 130 engaged therewith moves downward. In the present embodiment, the converting large gear 110 is provided with a converting handle 111, so that the converting large gear 110 can be driven to rotate more easily by the converting handle 111.
As shown in fig. 5 and 7, a locking pinion 121 is rotatably provided on the lifting locking spur 120, and the large transfer gear 110 drives the lifting locking spur 120 to lift, so that the locking pinion 121 is separated from or engaged with the spur of the retractable lock pin 300.

As shown in fig. 10 and 12, the locking pinion 121 is provided with a locking unidirectional rotation structure 122, and the unlocking pinion 131 is provided with an unlocking unidirectional rotation structure 132. In the present embodiment, the locking unidirectional rotation structure 122 is a counterclockwise unidirectional gear, and the unlocking pinion 131 is a clockwise unidirectional gear, it can be understood that the counterclockwise unidirectional gear can only move in a counterclockwise direction, and the clockwise unidirectional gear can only move in a clockwise direction.
Referring to fig. 9 and 10, in detail, the pressing driving mechanism 200 includes a pressing rotating rod 210 and an axial return elastic member 220, wherein in the present embodiment, the axial return elastic member 220 is a spring structure. The pressing rotating lever 210 is movably installed on the base 400 in an axial direction, and the axial return elastic member 220 is used to provide an axial elastic restoring force to the pressing rotating lever 210. One end of the pressing rotating lever 210 is provided with a pressing rotating gear 230, and the pressing rotating lever 210 drives the pressing rotating gear 230 to extend and contract so that the pressing rotating gear 230 is brought into contact with or separated from the locking unidirectional rotation structure 122 or the unlocking unidirectional rotation structure 132. In this embodiment, the pressing rotating lever 210 is provided with a pressing rotating handle 211, and the pressing rotating lever 210 can be pressed and rotated more easily by providing the pressing rotating handle 211.
As shown in fig. 11, it is specifically explained here that the locking one-way rotation structure 122 is a counterclockwise one-way gear, and the counterclockwise one-way gear is coaxial with the locking pinion 121; the lifting type locking straight tooth 120 is provided with a locking one-way limiting pin 123, and the locking one-way limiting pin 123 is pressed on the anticlockwise one-way gear through a spring 124; as shown in fig. 10, the pressing rotating lever 210 drives the pressing rotating gear 230 to extend and contract so that the pressing rotating gear 230 is engaged with or separated from the counterclockwise one-way gear.
Similarly, the unlocking unidirectional rotating structure 132 is a clockwise unidirectional gear, and the clockwise unidirectional gear is coaxial with the unlocking pinion 131; an unlocking one-way limiting lock (not shown) is arranged on the lifting unlocking straight tooth 130 and is pressed on the clockwise one-way gear through a spring. The pressing rotating lever 210 drives the pressing rotating gear 230 to extend and contract so that the pressing rotating gear 230 is engaged with or separated from the clockwise one-way gear.

during the descending process of the lifting type locking straight tooth 120, the locking pinion 121 on the lifting type locking straight tooth is meshed with the straight tooth of the telescopic lock pin 300;
then, by pressing the pressing rotary handle 211, the pressing rotary handle 211 further drives the pressing rotary rod 210 to move along the axial direction, so that the pressing rotary gear 230 on the pressing rotary rod 210 is engaged with the locking unidirectional rotation structure 122;
subsequently, the pressing rotary handle 211 is rotated clockwise, the pressing rotary handle 211 further drives the pressing rotary rod 210 to rotate clockwise, then the pressing rotary gear 230 on the pressing rotary rod 210 drives the locking one-way rotary structure 122 meshed therewith to rotate anticlockwise, the locking one-way rotary structure 122 further drives the locking pinion 121 to rotate anticlockwise, and the locking pinion 121 rotating anticlockwise drives the retractable lock pin 300 to enter the lock slot, so that the locking operation is realized;
the locking device 40 is subjected to an unlocking operation,
the conversion gear wheel 110 is rotated anticlockwise through the conversion handle 111, when the conversion gear wheel 110 rotates anticlockwise, the lifting type locking straight tooth 120 meshed with the conversion gear wheel can move upwards, and the lifting type unlocking straight tooth 130 meshed with the conversion gear wheel can move downwards;
during the descending process of the lifting unlocking straight tooth 130, the unlocking pinion 131 on the lifting unlocking straight tooth is meshed with the straight tooth of the telescopic lock pin 300;
then, by pressing the pressing rotary handle 211, the pressing rotary handle 211 further drives the pressing rotary rod 210 to move along the axial direction, so that the pressing rotary gear 230 on the pressing rotary rod 210 is engaged with the unlocking unidirectional rotation structure 132;
next, to pressing turning handle 211 and carrying out anticlockwise rotation operation, pressing turning handle 211 and then drive and press dwang 210 anticlockwise rotation, then, pressing on the dwang 210 and pressing rotating gear 230 can drive the one-way rotating structure 132 clockwise rotation of unblock of meshing with it, the one-way rotating structure 132 of unblock and then drive unblock pinion 131 clockwise rotation, clockwise pivoted unblock pinion 131 drives telescopic lock pin 300 again and breaks away from out from the locked groove, then, just realize unlocking operation.
As can be seen from the above description of the operation principle of the locking device 40, the locking device 40 of the present invention fully considers the thinking habits of people in the locking and unlocking processes, for example, in the locking process, the clockwise rotation operation is performed on the pressing rotating handle 211, the locking operation is finally realized in cooperation with the relevant components, in the unlocking process, the counterclockwise rotation operation is performed on the pressing rotating handle 211, and the unlocking operation is finally realized in cooperation with the relevant components. The locking is realized clockwise, and the unlocking is realized anticlockwise, so that the unlocking habit of people is met.
In the design process of the locking device 40, the locking or unlocking operation can be realized only by the cooperation of the opening-closing conversion mechanism 100 and the pressing type driving mechanism 200, which increases the complexity of locking or unlocking to a certain extent, so that the locking or unlocking operation is not too simple, and the locking or unlocking operation is in a proper position, thereby effectively improving the locking or unlocking safety.
Specifically, a locking unidirectional rotation structure 122 is disposed on the locking pinion 121, and the locking unidirectional rotation structure 122 can only rotate in the counterclockwise direction, so that the pressing rotation handle 211 can only rotate clockwise to drive the locking unidirectional rotation structure 122 to rotate counterclockwise to realize locking. If the locking unidirectional rotation structure 122 is not arranged, the locking pinion 121 has the capability of clockwise rotation, and the locking pinion 121 with the capability of clockwise rotation can drive the telescopic lock pin 300 to be separated from the lock groove to realize unlocking, so that the original purpose of design is seriously violated. In this regard, it is necessary to provide a locking one-way rotation structure 122 on the locking pinion 121.
Similarly, an unlocking unidirectional rotation structure 132 is provided on the unlocking pinion 131 for the same reason, and will not be described in detail herein.
It should be noted that, in the present invention, the pressing rotating rod 210 has both the pressing function and the rotating function, and the operator needs to press and rotate the pressing rotating rod 210 to finally lock or unlock, which further increases the complexity of unlocking, and only the inside operator who is very familiar with the operation can lock or unlock very smoothly.
