DETAILED DESCRIPTION

[0027] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0028] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 , an automatic reversing lock box, including a base 100, and also including: a lock tongue mechanism, including a tongue body 200 and a connecting member 300, the tongue body 200 is swingably connected to the connecting member 300, the tongue body 200 has a first inclined surface 210 and a second inclined surface 220 symmetrically arranged, the connecting member 300 drives the tongue body 200 to telescopically move inside and outside the base 100, and a first elastic member 310 is provided between the connecting member 300 and the base 100; a motor 400, which is installed in the base 100, and a transmission member 410 is provided at the rotating end of the motor 400; a baffle 500, which is rotatably installed in the base 100 and is located between the motor 400 and the lock tongue mechanism; wherein the transmission member 410 drives the baffle 500 to rotate to limit the telescopic movement of the tongue body 200.

[0029] This embodiment is described by taking application in a locker as an example. Fig.10When installing, the automatic reversing lock box is installed on the back of the door panel 610 through the base 100, and the lock box 630 corresponding to and matching the position of the tongue 200 is installed on the cabinet 620; in this embodiment, the upper and lower side walls of the baffle 500 are rotatably connected to the base 100 through the rotating shaft 510; when locking, the tongue 200 extends to the outside of the base 100, and the lock tongue extends into the lock box 630 on the cabinet 620. At this time, the motor 400 is started, and the transmission member 410 rotates to drive one end of the baffle 500 to rotate around the rotating shaft 510, and the end of the baffle 500 away from the transmission member 410 rotates to directly abut against the tongue 200, or the baffle 500 is locked. The end of the plate 500 away from the transmission member 410 rotates to the path where the tongue 200 retracts back into the base 100. At this time, the transmission member 410 and the baffle 500 remain stationary at the current position, and the baffle 500 is used to limit the retraction movement of the tongue 200 to achieve the locking purpose; when unlocking is required, the rotating end of the motor 400 rotates, and the baffle 500 rotates and resets at the same time, so that the end of the baffle 500 away from the transmission member 410 leaves the tongue 200 or leaves the retraction path of the tongue 200. Relative to canceling the retraction restriction of the tongue 200, the tongue 200 can freely retract into the base 100, and then unlocking is performed. The function of the motor 400 is to drive the rotation of the baffle 500, thereby realizing the limit control of the telescopic movement of the tongue 200. The rotation of the baffle 500 will not generate a large load on the motor 400. This action can be achieved by selecting a lower-power motor 400, thereby reducing the working power consumption of the motor 400 and effectively reducing the cost of the selected model of the motor 400. The structure is simple and the practicability is extremely high.

[0030] As for the lock tongue mechanism, this embodiment is explained by taking the door panel 610 swinging outward from the cabinet body as the door opening direction as an example; the first inclined surface 210 faces the outside of the cabinet body 620, and the second inclined surface 220 faces the inside of the cabinet body 620; in the following implementation mode, the motor 400 and the baffle 500 are in the unlocked state, and the tongue body 200 can be freely extended and retracted inside and outside the base 100. When the door panel 610 is in the closed state, the tongue body 200 extends out of the base 100 and is located in the lock box 630 of the cabinet body 620. At this time, the first inclined surface 210 is parallel to the door panel plane 611, which is equivalent to the first inclined surface 210 and the inner side wall 631 of the lock box being parallel to each other and abutting against each other, and the second inclined surface 220 is inclined to the door panel plane 611 in space; as Figure 5As shown, when the door needs to be opened, the user directly pushes the door panel 610 toward the outside of the cabinet 620. At this time, the first inclined surface 210 collides with the inner side wall 631 of the lock box. The first inclined surface 210 is subjected to the force of the inner side wall 631 of the lock box toward the inside of the cabinet 620, and the tongue 200 swings toward the inside of the cabinet 620. The tongue 200 switches to a state in which the first inclined surface 210 is inclined to the door panel plane 611 and the second inclined surface 220 is parallel to the door panel plane 611 in space. Then, the first inclined surface 210 cuts into the lock box 631. 0, and the tongue 200 and the connecting member 300 retract into the base 100, and the first elastic member 310 is elastically compressed until the door panel 610 opens and leaves the cabinet 620. After the tongue 200 loses the interaction force of the lock box 630, the first elastic member 310 elastically resets and pushes the connecting member 300 to make the tongue 200 extend out of the base 100. At this time, the position of the tongue 200 is that the first inclined surface 210 is inclined to the door panel plane 611, and the second inclined surface 220 is parallel to the door panel plane 611; Figure 6 As shown, during the door closing process, the second inclined surface 220 of the tongue 200 first contacts the outer wall of the lock box 630, which is equivalent to the outer wall of the lock box 630 applying a force toward the outside of the cabinet 620 to the second inclined surface 220. After the force is applied, the tongue 200 swings toward the outside of the cabinet 620. At this time, the spatial position of the tongue 200 switches to the first inclined surface 210 parallel to the door panel plane 611, and the second inclined surface 220 is inclined to the door panel plane 611. Then, the second inclined surface 220 is subjected to the lock box 630. The tongue 200 and the connecting member 300 retract into the base 100 together with the force, and the first elastic member 310 is elastically compressed until the door panel 610 is fully closed. The first elastic member 310 elastically resets and pushes the connecting member 300 to extend the tongue 200 out of the base 100. The tongue 200 is stuck in the lock box 630 to complete the door closing. At this time, the position of the tongue 200 is that the first inclined surface 210 is parallel to the door panel plane 611, and the second inclined surface 220 is inclined to the door panel plane 611. By swinging the tongue 200, the first inclined surface 210 and the second inclined surface 220 are used as the force-bearing surfaces for opening and closing the door in turn. In combination with the connecting member 300 and the first elastic member 310, the user can directly push the door panel 610 with any part of the body to drive the tongue 200 to automatically extend and retract inside and outside the base 100 to complete the door opening and closing. It is very convenient to use.

[0031] The present invention greatly optimizes the internal structure of the lock through the swinging tongue 200 structure of the lock tongue mechanism, in conjunction with the limiting action of the motor 400 and the baffle 500, effectively reducing the load of the motor 400 and making it convenient for users to open and close the door when the lock is unlocked.

[0032] During the swinging process of the tongue 200, the front and rear side walls of the base 100 parallel to the door panel plane 611 can be directly used to abut against the first inclined surface 210 or the second inclined surface 220, so as to limit the tongue 200 from swinging until the first inclined surface 210 or the second inclined surface 220 is parallel to the door panel plane 611. The operation of the motor 400 can be controlled by an existing remote control module or a password input module.

[0033] In some specific embodiments of the present invention, a sharp corner portion 230 is provided at the rear end of the tongue 200, a sliding member 320 with an arc surface is provided inside the connecting member 300, the sliding member 320 slides inside the connecting member 300, and a second elastic member 330 is provided between the sliding member 320 and the connecting member 300; wherein, during the swinging process of the tongue 200, the sharp corner portion 230 slides along the arc surface. Figure 3 and Figure 4 As shown, the sliding member 320 can be made of a steel ball, and the second elastic member 330 can be made of a cylindrical spring; when the tongue 200 swings on the connecting member 300, the sharp corner 230 on the tongue 200 acts on the sliding member 320, and the sharp corner 230 moves along the arc surface on the sliding member 320, and the sliding member 320 retreats under the force, and at the same time compresses the second elastic member 330, which is equivalent to the sliding member 320 having a certain damping effect on the tongue 200 during the swinging process of the tongue 200; in the normal state, the inclined surfaces on both sides of the sharp corner are tangent to the arc surface of the sliding member 320, and the sliding member 320 is used to ensure that the tongue 200 can still remain motionless in the current position under the action of an external force less than the compression force of the second elastic member 330.

[0034] In some specific embodiments of the present invention, Figure 2 and Figure 4 As shown, a protruding block 240 is provided on the tongue 200. The protruding block 240 cooperates with the baffle 500, and the baffle 500 abuts against the protruding block 240, thereby limiting the swing of the tongue 200, thereby locking the tongue 200 when the door is closed.

[0035] In some specific embodiments of the present invention, Figure 2 , Figure 3 and Figure 4 As shown, a mounting portion 340 is provided at the rear end of the connecting member 300, one end of the first elastic member 310 is inserted into and abuts against the mounting portion 340, and the other end of the first elastic member 310 abuts against the inner wall of the base 100; the first elastic member 310 can selectively use a cylindrical spring, and the mounting portion 340 limits the first elastic member 310 to prevent off-axis swing of the first elastic member 310 during extension and retraction.

[0036] In some specific embodiments of the present invention, Figure 2 , Figure 7 and Fig. 9As shown, a third elastic member 520 is provided between the base 100 and the side of the baffle 500 facing away from the transmission member 410 . One end of the third elastic member 520 abuts against the back of one end of the baffle 500 that is linked to the transmission member 410; in the unlocked state, the motor 400 is started, and the transmission member 410 is used to push the baffle 500 to rotate, so that the end of the baffle 500 away from the transmission member 410 leaves the tongue 200 or leaves the retraction path of the tongue 200. At this time, the end of the baffle 500 close to the transmission member 410 compresses the third elastic member 520; when switching from the unlocked state to the locked state, the motor 400 is started, and the transmission member 410 rotates to cancel the thrust generated on the baffle 500 during unlocking. At this time, the baffle 500 rotates due to the elastic force of the third elastic member 520, and the end of the baffle 500 away from the transmission member is re-abutted against the tongue 200 or placed on the retraction path of the tongue 200; the forward and reverse rotation of the baffle 500 is achieved by the cooperation of the third elastic member 520 and the transmission member.

[0037] In some specific embodiments of the present invention, Figure 1 , Figure 2 and Fig. 9 As shown, it also includes a travel switch 700 connected to the motor 400, and the elastic sensing pressure head 710 of the travel switch 700 abuts against the side wall of the baffle 500 at one end close to the transmission member 410; when the baffle 500 rotates, the elastic sensing pressure head 710 of the travel switch 700 is used to sense and detect the rotation position of the baffle 500, and then the signal is fed back to the motor 400, thereby controlling the forward and reverse travel of the motor 400.

[0038] In some specific embodiments of the present invention, Figure 8 As shown, the transmission member 410 is an eccentric wheel or a cam; the eccentric action of the eccentric wheel or the cam is used to drive the baffle 500 to rotate.

[0039] In some specific embodiments of the present invention, Figure 3 and Figure 4 As shown, the tongue body 200 and the connecting member 300 are connected via an axle pin 250 ; when the door is opened or closed, the tongue body 200 is forced to swing, which is equivalent to the tongue body 200 rotating around the axle pin 250 .
