[0031] Example

[0032] This embodiment provides Figure 1-7The electric control lock for intelligent cabinets shown in the figure comprises a lock hook 5 and a lock buckle 4 rotatably arranged on a lock shell 1, and a push rod structure 2 connecting the lock buckle 4 and a driving device 3, a lock port 11 is arranged on the lock body, and the lock hook 5 and the lock buckle 4 cooperate to have a locked state of resisting the lock port 11, and an unlocked state of separating and opening the lock port 11, the push rod structure 2 reciprocates under the drive of the driving device 3, and is used to drive the lock buckle 4 and the lock hook 5 to switch from the locked state to the unlocked state; wherein, a limiting structure is arranged between the push rod structure 2 and the lock shell 1, the limiting structure comprises a limiting guide groove 6 extending along the movement direction of the push rod structure 2 and arranged on the lock shell 1, and a limiting guide block 7 sleeved on the push rod structure 2 and slidably connected to the limiting guide groove 6, an elastic member 8 is arranged between the limiting guide block 7 and the push rod structure 2 to form an elastic connection between the two, and when the push rod structure 2 reciprocates, the elastic member 8 applies a force to the limiting guide block 7 to slide along the limiting guide groove 6.

[0033] The above implementation is the core technical solution of this embodiment. According to the limit guide block 7 slidably connected to the limit guide groove 6, the push rod structure 2 is sleeved with the limit guide block 7, and the cooperation between the limit guide block 7 and the limit guide groove 6 guides the movement of the push rod structure 2 to prevent the push rod structure 2 from deviating during the reciprocating movement. The limit guide block 7 and the push rod structure 2 are elastically connected through the elastic member 8, so that the force generated by the movement of the push rod structure 2 is transmitted to the limit guide block 7 by squeezing the elastic member 8, thereby driving the limit guide block 7 to move in the same direction. During the unlocking operation, the limit guide block 7 After the push rod structure 2 completes unlocking the lock hook 5 and the lock buckle 4 under the drive of the driving device 3, it drives the limit guide block 7 to slide and contact one end of the limit guide groove 6 and is blocked by the limit. Since the driving device is still running, it will drive the push rod structure to continue moving a short distance, thereby driving the push rod structure 2 to move relative to the limit guide block by compressing the elastic member 8, so as to avoid movement obstruction, wear and even jamming between the push rod structure and the driving device, effectively protecting the driving device, improving the product life and performance, and ensuring that the electric control lock is safely and reliably used in smart cabinet equipment.

[0034] In this embodiment, if Figure 1-3 As shown, the lock housing 1 is provided with a mounting cavity 12 for mounting the driving device 3, the driving device 3 comprises a motor 31 disposed in the mounting cavity 12 and a gear assembly connected to the motor 31, the gear assembly having a driving gear 32 extending out of the mounting cavity 12, and one end of the push rod structure 2 is provided with a rack 24 meshing with the driving gear 32. The motor 31 drives the push rod structure 2 to perform linear motion on the lock housing 1 through a gear transmission, and the push rod structure 2 drives the lock buckle 4 to rotate, thereby driving the lock hook 5 to separate from the lock buckle 4, so as to realize the automatic unlocking function of the product.

[0035] As a specific structural setting, the lock hook 5 and the lock buckle 4 are rotatably arranged on the lock housing 1 through two rotating shafts, and two reset torsion springs connecting the lock hook 5 and the lock buckle 4 are respectively arranged on the two rotating shafts. Figure 6 As shown, a toggle block 41 is coaxially linked to the bottom of the lock buckle 4, and a connecting groove 25 is extended along the length direction of the bottom side of the push rod structure 2. The toggle block 41 has a protrusion extending into the connecting groove 25, and the protrusion is V-shaped. One end of the connecting groove is provided with a driving groove 26 matched with the protrusion. When the push rod structure 2 is unlocked, the driving groove 26 pushes the toggle block 41 to rotate a certain angle, thereby driving the lock buckle 4 to rotate and separate from the lock hook 5. When the lock hook 5 is separated from the lock buckle 4, it will quickly rotate to open the lock mouth 11 under the action of two reset torsion springs to complete the unlocking operation.

[0036] Combine the following Figure 3-7 The installation method of the push rod structure and the limit guide block is explained in detail:

[0037] The push rod structure 2 includes a straight plate portion 21 connected to the limiting guide block 7, and a positioning hole 22 opened on the straight plate portion 21. The elastic member 8 is a spring component arranged in the positioning hole 22, and two positioning blocks connected to the two ends of the spring component are arranged at both ends of the positioning hole 22, so that the spring component is positioned and installed in the positioning hole 22. It is further preferably arranged that the limiting guide block 7 is provided with a strip slot 71 that is matched with the straight plate portion 21, and a receiving groove 72 formed in the strip slot 71 and suitable for accommodating the spring component, the width of the receiving groove 72 is greater than the width of the strip slot, and the diameter of the spring component is greater than the width of the straight plate portion 21. The limiting guide block 7 with such an installation design surrounds the spring component through the receiving groove, so that the The two ends of the spring component are respectively matched and abutted against the two ends of the accommodating groove 72. With this structural setting, the spring component plays a role in transmitting motion and force between the push rod structure and the limiting guide. The push rod structure 2 applies a thrust to the limiting guide block 7 by squeezing one end of the spring component during the movement, thereby driving the limiting guide block 7 to slide along the limiting guide groove 6, and realizing the elastic connection relationship between the push rod structure 2 and the limiting guide; in addition, the spring component can also play a buffering role between the push rod structure 2 and the limiting guide, especially when the limiting guide block 7 no longer moves when it slides to one end of the limiting guide groove 6. At this time, the push rod structure 2 can complete its own movement stroke by squeezing the spring component under the drive of the motor 31, avoiding the situation of causing the motor 31 to be blocked and damaged and the gear wear. In this embodiment, as an alternative method mentioned above, the elastic member 8 can also be selected as a spring sheet structure arranged in the positioning hole of the push rod structure, and the spring sheet structure is in an arc shape or a V shape, so that its two ends abut against the inner wall of the accommodating groove of the limiting guide block, and the elastic connection between the push rod structure and the limiting guide block can also be realized. Those skilled in the art can select the specific structure of the elastic member based on the above description, and no further details are given here.

[0038] For further optimization, refer to Figure 7As shown, the limiting guide block 7 includes a U-shaped body 73 provided with a strip slot 71, and a slide bar 74 connected to the bottom side of the U-shaped body 73, and the slide bar 74 is slidably connected to the limiting guide groove 6. After the U-shaped body 73 is sleeved on the straight plate 21 through the strip slot 71, the bottom of the U-shaped body 73 is limited by the lock shell 1, so that the limiting guide block 7 will not fall off from the straight plate 21 after installation. Among them, the push rod structure 2 includes two limiting surfaces 23 respectively arranged on both sides of the straight plate 21, and the top of the limiting guide block 7 abuts against the two limiting surfaces 23, so that the opening position of the accommodating groove 72 is blocked, so that the limiting guide block 7 cooperates with the push rod structure 2 to form a closed space surrounding the spring component, thereby realizing the hidden installation of the spring component, and the installation is more neat and beautiful, which is conducive to improving the safety and reliability of the use of the spring component.

[0039] The electric lock of this embodiment also includes a detection structure for detecting the position state of the lock hook 5. Figure 2 and Figure 5 As shown, the detection structure includes a reed switch 13 arranged in the lock housing 1, and a magnetic block 14 arranged on the lock hook 5. The lock hook 5 drives the magnetic block 14 to rotate close to the reed switch 13 in the locked state. It is further preferably configured that the lock hook 5 has a U-shaped lock groove and a short hook arm 51 and a long hook arm 52 respectively arranged on both sides of the U-shaped lock groove, and the bottom surface of the long hook arm 52 is provided with an assembly hole for installing the magnetic block 14. The lock hook 5 drives the long hook arm 52 to rotate and is located above the reed switch 13 in the locked state, so that the reed switch 13 is triggered to open when it detects the magnetic block 14. This reed switch 13 is subjected to the external magnetic field, which causes the two magnetic reed sheets inside it to contact, thereby connecting the circuit to send a signal, and has the characteristics of small size, light weight, and resistance to external interference. With this structural arrangement, when the electric lock is locked, the lock hook 5 and the lock buckle 4 will remain in a locked state. At this time, the lock hook 5 drives the magnetic block 14 to approach the position of the reed switch 13, so that the reed switch 13 is triggered to open and send an indication signal for indicating that the electric lock has completed locking. Conversely, when the electric lock is unlocked, the lock hook 5 and the lock buckle 4 will be in a separated unlocked state. At this time, the lock hook 5 drives the magnetic block 14 away from the position of the reed switch 13, so that the reed switch 13 is closed and sends an indication signal for indicating that the electric lock is unlocked. Therefore, the cooperation between the reed switch 13 and the magnetic block 14 can detect the locked or unlocked status information of the electric lock, so that the user can know the working status of the electric lock and avoid signal loss and misjudgment.

[0040] In order to ensure that the electric lock can automatically open the cabinet door when unlocking, the push rod structure 2 is provided with a push-out structure 9 for pushing the cabinet door open when the lock hook 5 is unlocked. Figure 3As shown, the ejection structure 9 includes a groove structure 91 extending along the movement direction of the push rod structure 2 and arranged on the push rod structure 2, a guide hole arranged at one end of the push rod structure 2 and connected to the groove structure 91, and a push rod 92 and a push rod spring 93 movably arranged in the groove structure 91, one end of the push rod 92 is pressed and contacted with the push rod spring 93, and the other end thereof is penetrated in the guide hole, and a limiting boss 94 is arranged in the groove structure 91 to form a limiting match with the push rod 92, and the limiting boss 94 is used to limit the moving distance of the push rod 92. It can be seen from the above structure that when the lock hook 5 and the lock buckle 4 are unlocked and separated under the drive of the push rod structure 2, the locking effect on the cabinet door lock rod is released, so that the cabinet door lock rod can be separated from the lock port 11 of the electric lock, and at this time, the push rod 92 extends out of the guide hole under the action of the push rod spring and acts on the cabinet door, so as to push the cabinet door open, so as to achieve the effect that the electric lock automatically opens the cabinet door after unlocking, which is more convenient to use and improves the product performance.

[0041] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
