Detailed Description
The invention will be described in detail with reference to the drawings and specific embodiments, wherein the exemplary embodiments and descriptions are provided to explain the invention, but not to limit the invention.
Example (b):
hatch door switch control assembly of automatic vending machine, its characterized in that: comprises a lock ring 1, a lock catch component, a brake component and a main control board 4.
In this embodiment, the locking ring 1 is fixed to the door by screws and structural members for locking the door in cooperation with the locking assembly.
In this embodiment, the latch assembly comprises a latch 201, a torsion spring 202, and a fixed rotating shaft 203, the torsion spring 202 is sleeved in the fixed rotating shaft 203, two side spring arms clamp the latch 201, and the torsion spring 202 is stressed when the latch 201 rotates clockwise around the fixed rotating shaft 203.
In an embodiment of the present invention, the braking component is composed of a fixed component 301, a movable component 302, and a sleeve 303, the movable component 302 is an independent iron core, and there is no coil winding on the iron core, and the end of the movable component 302 is connected to the latch 201 in the latch component through a movable rotating shaft 304. And the fixing assembly 301 is fixed in the cabin through a structural member, and a coil of the fixing assembly 301 is connected to the main control panel 4 through a lead. The moving member 302 has a protruding portion at the top end thereof for limiting the position, and the diameter of the portion other than the top end is smaller than the inner diameter of the sleeve 303. The sleeve 303 is secured within the bay by structural members and screws for limiting non-axial displacement of the moving assembly 302. The coil of the fixing component 301 is connected to the output end of the direct current positive-negative pole switching circuit after being connected to the main control board 4.
The working steps are as follows:
in the unpowered state, the latch 201 is stationary.
S1: locking action of the lock ring 1:
the action position of the lock ring 1 is located on the left side of the arc at the top end of the lock catch 201, the lock ring 1 pushes the lock catch 201 to rotate clockwise under the action of external thrust until the lock ring 1 slides over the arc end of the lock catch 201, and the lock catch 201 resets under the action of the reaction force of the torsion spring 202 to lock the lock ring 1 to complete locking.
S2: unlocking action:
the main control board 4 receives the unlocking instruction through the bluetooth module, the output end of the direct current positive-negative pole switching circuit supplies power to the coils of the fixed assembly 301 and the movable assembly 302, so that an electromagnetic field is generated, the adjacent end parts of the fixed assembly 301 and the movable assembly 302 are mutually attracted, and the fixed assembly 301 is immovable, so that the movable assembly 302 can generate leftward displacement until contacting with the end part of the fixed assembly 301, and the movable assembly 302 drives the lock catch 201 to rotate clockwise through the movable rotating shaft 304, so that the tail end of the lock catch 201 is separated from the lock ring 1, and the cabin door can be opened by external force.
After the hatch door is opened, the coil of the fixing component 301 is powered off, that is, the output voltage of the output end of the direct current positive-negative switching circuit is 0, and the lock catch 201 resets under the action of the torsion spring 202.
Because the iron core also can produce magnetism under the effect of long-term electromagnetic field, in order to eliminate the influence of this kind of legacy magnetic field, the utility model discloses in, being equipped with on the main control board 4 and receiving direct current positive negative pole switching circuit, relay K1, K2, K3, K4 among the positive negative pole switching circuit all adopt high-power relay, and safe current is greater than 20A. During actual operation, the positive and negative poles of the input end are changed once each unlocking action is completed.
The program burned on the main control board 4 executes the following operations to exchange the power supply polarity of the coil:
s1: controlling the relays K1 and K3 to be switched on, and the relays K2 and K4 to be switched off, so that the pad P1 is connected to the positive pole of the power supply, and the pad P2 is connected to the negative pole of the power supply;
s2: when the direction is reversed, the control relays K2 and K4 are switched on, and the relays K1 and K3 are switched off, so that the pad P2 is connected to the positive pole of the power supply, and the pad P1 is connected to the negative pole of the power supply.
The above operation can complete the power supply polarity switching operation, so that the coil of the fixing component 301 can switch the polarity after completing the one-time door opening operation, and generate the electromagnetic field with opposite directions.
In another embodiment of the present invention, as shown in fig. 2, the moving component 302 is a combination L of a coil and a core. The coil winding directions of the fixed component 301 and the moving component 302 are the same. This combination may result in a stronger attractive or repulsive force between the moving component 302 and the stationary component 301. When one coil has a problem, the other coil can maintain the whole component to operate, and the condition of failure is avoided. At this time, two sets of dc positive-negative switching circuits on the main control board 4 are respectively connected to the coils of the movable assembly 302 and the fixed assembly 301.
When the attraction force needs to be generated, the main control board 4 outputs direct current with the same polarity to the coils of the fixed component 301 and the movable component 302, so that the adjacent ends of the fixed component 301 and the movable component 302 have different magnetism and attract each other. Thereby moving the moving member 302 to the left and driving the lock 201 to rotate along the pointer and leave the lock ring.
The two embodiments can realize the control of the opening and closing state of the cabin door, and have better practicability.
The above description is only an embodiment of the present invention, and does not limit the present invention, and those skilled in the art can make various modifications and variations. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
