Please refer to Figures 1 to 4, which correspond to an electric control storage box of a preferred embodiment of the present invention, including: a shell 100, having a push-pull opening 11; a drawer 200, which is accommodated in the shell 100 and can be pulled out from the push-pull opening 11; and a locking mechanism 300, including a blocking member 31 rotatably arranged on the shell 100, an elastic member (not shown) connected to the blocking member 31, a hook member 32 slidably arranged on the shell 100, and a driving member 33 for driving the hook member 32 to slide; wherein the blocking member 31 has a first position for limiting the drawer 200 from moving away from the shell 100 and a second position for releasing the limitation, the hook member 32 has a locking state and an unlocking state, the blocking member 31 responds to the hook member 32 switching from the locking state to the unlocking state and rotates from the first position to the second position under the action of the elastic member, when the blocking member 31 rotates from the second position to the first position, the hook member 32 is in a locking state and limits the blocking member 31 from rotating to the second position.

The locking mechanism 300 of the present invention includes a blocking member 31 rotatably arranged on the outer shell 100, an elastic member connected to the blocking member 31, a hook member 32 slidably arranged on the outer shell 100, and a driving member 33 driving the hook member 32 to slide. The driving member 33 drives the hook member 32 to slide, and the hook member 32 can keep the blocking member 31 in the first position to block the drawer 200, or allow the blocking member 31 to rotate to the second position to release the obstruction to the drawer 200, thereby realizing the locking or unlocking of the drawer 200. The above-mentioned locking mechanism 300 has a simple and reliable structure, good stability, will not cause jamming during operation, and effectively reduces the failure rate.

Furthermore, the housing 100 includes a top plate 12, a bottom plate 13, and two opposite side plates 14 connected between the top plate 12 and the bottom plate 13. The bottom plate 13, the top plate 12, and the side plates 14 cooperate to form a receiving cavity 15 adapted to the drawer 200, and the receiving cavity 15 has a push-pull opening 11. Preferably, a pull-out portion 16 is provided on both the top plate 12 and the bottom plate 13. The two pull-out portions 16 are arranged opposite to each other and extend to the push-pull opening 11 along the pulling direction of the drawer 200. The pull-out portion 16 is specifically a slot structure that penetrates the receiving cavity 15, so that part of the top and bottom surfaces of the drawer 200 are exposed to the outside, thereby facilitating the operator to pull out the drawer 200 from the housing 100.

Furthermore, the blocking member 31 is arranged on one side of the housing 100 located at the push-pull opening 11, and the blocking member 31 is rotatably connected to the housing 100 via a rotating shaft (not shown). In this embodiment, in order to ensure the installation space, the rotation axis direction of the blocking member 31 is perpendicular to the top plate 12 and/or the bottom plate 13 of the housing 100. The elastic member can be a torsion spring sleeved on the rotating shaft and in contact with the blocking member 31, so that the blocking member 31 is deformed when it is rotated to the first position by force, and resets and drives the blocking member 31 to rotate to the second position when the external force is removed.

The blocking member 31 includes a blocking plate 311 and a first hook plate 312 connected to the blocking plate 311. When the blocking member 31 is in the first position, the projection of the blocking plate 311 in the push-pull direction of the drawer 200 is located on the drawer 200, so that the drawer 200 can be effectively blocked when the drawer 200 is pulled out of the housing 100 along the push-pull direction. When the blocking member 31 is in the second position, the projection of the blocking plate 311 in the push-pull direction of the drawer 200 is not located on the drawer 200, so that the drawer 200 can be smoothly pulled out of the housing 100.

The first hook plate 312 is used for engaging with the hook member 32. The outer contour of the first hook plate 312 is fan-shaped or substantially fan-shaped, one non-arc edge of the first hook plate 312 is connected to the edge of the baffle 311, and the other non-arc edge extends toward the hook member 32 with a hook portion 313. By adopting the above structure, sharp edges and corners can be effectively avoided, so as to improve safety when the operator pushes and pulls the drawer 200.

Preferably, there are two first hook plates 312, which are respectively arranged above the top plate 12 and below the bottom plate 13. The hook member 32 cooperates with the two first hook plates 312 at the same time, thereby further improving the reliability of locking. In addition, by arranging the first hook plates 312 above the top plate 12 and below the bottom plate 13, when the blocking member 31 is in the second position, the first hook plates 312 can be rotated to the outside of the push-pull opening 11, so that it can play a role in guiding and supporting the drawer 200, making it more convenient to push and pull the drawer 200.

Furthermore, the hook member 32 includes a transmission plate 321 and a second hook plate 322 connected to the transmission plate 321. The transmission plate 321 is slidably connected to the housing 100, and the top plate 12 and the bottom plate 13 are respectively extended from both sides of the second hook plate 322 to respectively cooperate with the two hook portions 313. In this embodiment, in order to ensure installation space, the sliding direction of the hook member 32 is consistent with the push-pull direction of the drawer 200.

Preferably, the transmission plate 321 extends to the side of the housing 100 opposite to the push-pull opening 11, and the driving member 33 is in transmission connection with the side of the transmission plate 321 away from the second hook plate 322. Since the installation space around the housing 100 is limited, by adopting the above structure, the driving member 33 can be installed on the side of the housing 100 opposite to the push-pull opening 11, so as to facilitate assembly and transmission of the transmission plate 321. In this embodiment, the driving member 33 is specifically an electric push rod to push the hook member 32 to slide.

Preferably, in order to facilitate assembly and simplify the structure, in this embodiment, the hook member 32 is disposed on the inner side of the side plate 14, and the two sides of the transmission plate 321 are respectively in contact with the top plate 12 and the bottom plate 13 to guide the sliding of the transmission plate 321. The housing 100 is provided with a notch 17 extending from the top plate 12 to the bottom plate 13 along the rotation axis direction of the blocking member 31 to drive the second hook plate 322 to extend out of the top plate 12 and the bottom plate 13.

Preferably, the notch 17 extends a certain distance along the push-pull direction of the drawer 200 to drive the second hook plate 322 to move along the push-pull direction in the notch 17. The notch 17 has a first stop wall 171 and a second stop wall 172 in the push-pull direction. When the hook member 32 slides to the first stop wall 171, the hook member 32 is in a hooked state, and when the hook member 32 slides to the second stop wall 172, the hook member 32 is in an unlocked state.

Furthermore, in order to drive the blocking member 31 in the second position to rotate to the first position and engage with the hook member 32, in one embodiment, the storage box is provided with a detection structure (not shown) for detecting the rotation of the blocking member 31, and the detection structure is connected to the signal of the driving member 33. When the blocking member 31 rotates to the second position, the detection structure can detect the blocking member 31 and drive the hook member 32 to move from the unlocked state to the engaged state. Indeed, in another embodiment, when the driving member 33 drives the hook member 32 to switch from the engaged state to the unlocked state and unlocks the blocking member 31, the driving member 33 can drive the hook member 32 to return to the engaged state, and an elastic structure can be set between the second hook plate 322 and the transmission plate 321, or the second hook plate 322 has a certain elasticity. When the blocking member 31 turns to the first position, the first hook plate 312 first contacts the second hook plate 322, and as it gradually rotates, the elastic structure is compressed or the second hook plate 322 is deformed, so that the second hook plate 322 can avoid the first hook plate 312, so that the blocking member 31 reaches the first position, and when reaching the first position, the elastic structure or the second hook plate 322 is reset to drive the first hook plate 312 and the second hook plate 322 to engage with each other.

Preferably, the housing 100, the blocking member 31 and the hook member 32 are all made of sheet metal to improve the stability of the overall structure of the storage box.

Furthermore, a detection sensor 400 is provided on the housing 100 for detecting whether there are objects in the storage space in the drawer 200 . The detection sensor 400 is specifically a capacitive sensor so as to prompt the operator of the situation in the drawer 200 .

The use process of the present invention is as follows: when the drawer 200 needs to be pulled out from the push-pull opening 11 of the shell 100, the driving member 33 pushes the hook member 32 to move to the unlocked state. At this time, the blocking member 31 is not engaged with the hook member 32, and the blocking member 31 moves from the first position to the second position under the action of the elastic member; when the drawer 200 needs to be locked, the drawer 200 is pushed into the shell 100 from the push-pull opening 11, and then the blocking member 31 is moved from the second position to the first position. At this time, the blocking member 31 is engaged with the hook member 32 to limit the blocking member 31 from moving back to the second position, thereby completing the locking.

In addition, the present invention also provides a storage cabinet, including the aforementioned electric control storage box and a cabinet frame (not shown), the storage box array is arranged on the cabinet frame, and the cabinet frame is fixedly connected to the outer shell 100 of the storage box.
