[0032] Reference Figures 1 to 6 , a rear unlocking box, comprising:
[0033] The box body 10 has a storage cavity 11 formed therein. An inner end surface of the storage cavity 11 has an extension hole 111 extending from the inner end surface of the box body 10 to the rear surface of the box body 10.
[0034] A drawer 20 is provided with a locking rod 21 at the end of the drawer 20, and a locking portion is provided on the locking rod 21. The drawer 20 is movably inserted into the storage cavity 11. When the drawer 20 is fully inserted into the storage cavity 11, the locking rod 21 is inserted into the extension hole 111 and the locking portion is located at the rear side of the box body 10;
[0035] A lock member is provided on the rear side of the box body 10 and can abut and lock with the locking portion;
[0036] The driver 40 has an output end that cooperates with the lock element and is used to drive the lock element to move.
[0037] The utility model also discloses a vehicle-mounted refrigerator, which applies the above-mentioned rear-unlockable box.
[0038] By providing a locking rod 21 at the end of the drawer 20, an extension hole 111 that passes through to the rear surface of the box body 10 is provided on the inner end surface of the storage cavity 11, a locking portion is provided on the locking rod 21, and a lock element for locking and unlocking the lock element is arranged on the rear side of the box body 10. When the drawer 20 is closed, the drawer 20 is completely pushed into the storage cavity 11, so that the locking rod 21 passes through the extension hole 111 to move the lock element to the rear side of the box body 10, and then the lock element is locked with the lock element. When unlocking is required, the lock element is driven by the driver 40 to unlock the lock element, thereby releasing the lock element, and the drawer 20 can be pulled out smoothly. Through this structure, the lock body and the lock element do not need to occupy the space of the storage cavity 11, and secondly, when the drawer 20 is opened, the lock body and the lock element will not be exposed to the outside, thereby avoiding the risk of being damaged by touch.
[0039] In the above solution, the output end of the driver 40 can be directly fixed to the lock element, and the process of locking and unlocking the drawer 20 is achieved by the driver 40 driving the lock element. However, this method is relatively cumbersome for the operation design of the driver 40. For this reason, it is preferred that a return spring 50 is provided on the rear side of the box body 10 to abut against the lock element. The return spring 50 applies a force to the lock element to move toward the lock body, and the driver 40 applies a force to the lock element to move away from the lock body. When locking, the driver 40 resets, and the return spring 50 automatically drives the lock element to move toward the lock portion to lock. When unlocking, the driver 40 moves toward the lock element again and drives the lock element to overcome the elastic force of the return spring 50 and move away from the lock portion, thereby completing the unlocking.
[0040] Preferably, the return spring 50 is arranged at the bottom of the lock element, and the motor is arranged above the lock element.
[0041] In this solution, in order to limit the travel of the lock, a stopper is preferably provided on the rear side of the box body 10, and a limiting member is provided on the lock, and the stopper is used to abut against the limiting member to limit the maximum travel of the lock.
[0042] Specifically, it is preferred that the stop member is an installation box 60 arranged on the rear surface of the box body, and a first limit hook 61 is provided on the inner wall of the installation box 60. The limiting member is a second limit hook 34 provided on the lock member, and the second limit hook 34 can be hooked with the first limit hook 61. In this structure, the reset spring 50 can be synchronously provided in the installation box 60, thereby simplifying the structure.
[0043] In other embodiments, the limiting member may be directly the surface of the locking member, and the stopping member may be a stopping plate abutting against the surface of the locking member.
[0044] In this solution, the locking element preferably includes:
[0045] A locking seat 30 is provided with a through hole 31 extending from front to back. A locking tongue 32 is provided on the inner wall of the through hole 31 and extends toward the middle of the through hole 31. The through hole 31 is directly opposite to the extension hole 111.
[0046] The locking portion is a locking hole 22 provided on the surface of the locking rod 21 and used for the locking tongue 32 to enter.
[0047] When locking, the end of the locking rod 21 is inserted into the through hole 31 of the locking seat 30, and the locking tongue 32 is inserted into the locking hole 22 to form locking.
[0048] In this solution, it is preferred that the end of the locking rod 21 is provided with a first guide slope 23 inclined toward the direction of the locking tongue 32, and the front end surface of the locking tongue 32 is provided with a second guide slope 33, so that when the drawer 20 is pushed into the storage cavity 11, the first guide slope 23 and the second guide slope 33 cooperate with each other, thereby driving the locking seat 30 to overcome the elastic force of the reset spring 50 and move, so that the locking tongue 32 can move smoothly along the surface of the locking rod 21 until it is inserted into the lock hole 22.
[0049] In other embodiments, the locking element may be a first pin plate, and the locking portion may be a second pin plate provided on the locking rod 21 , and the surfaces of the first pin plate and the second pin plate may abut against each other.
[0050] In other embodiments, the locking element may also be a hook, the driver 40 is connected to the hook and drives it to rotate, and the locking portion is a slot provided on the locking rod 21, and the hook can be inserted into the slot when rotating.
[0051] Taking into account that the box body of this solution is used in a car refrigerator, and the car refrigerator needs to consider the efficiency of cold air dissipation, it is preferred that the rear surface of the box body 10 is provided with a cover that is movable to cover the extension hole 111. When the drawer 20 is opened and the locking rod 21 is moved into the storage cavity 11, the cover covers the extension hole 111. When the drawer 20 is closed, the locking rod 21 lifts the cover so that it can be smoothly moved to the rear side of the box body 10.
[0052] In this embodiment, the cover preferably includes an outer ring 70 and a plurality of elastic flaps 71 disposed inside the outer ring 70. The outer ring 70 is fixed to the rear surface of the box body 10 and is located outside the extension hole 111. The elastic flaps 71 face the center of the extension hole 111, and all the elastic flaps 71 together cover the extension hole 111. In other embodiments, the cover may also be a swing baffle fixed to the rear surface of the box body 10 by a torsion spring.
[0053] The box in this solution is generally integrated and fixed in a car or other specific settings, and the rear side of the box body 10 will be hidden in other equipment.
[0054] If the box of this solution is to be used independently, it is preferred that a cover lock and an outer cover of the driver 40 are provided on the rear side of the box body 10 .
[0055] The above are only preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the practical concept of the present invention, or directly or indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
