As shown in fig. 1-3, the utility model provides an automatic lock body, including lock box 1, lock box 1 can be the structure of approximate cuboid usually, be equipped with main spring bolt 2 and scissors spring bolt 3 in the lock box 1, main spring bolt 2 can be square or circular shape spring bolt, scissors spring bolt 3 then can be the oblique spring bolt that has the inclined plane, the lateral wall of lock box 1 is equipped with first lockhole (not shown in the figure) and second lockhole (not shown in the figure), under the lock-out state, main spring bolt 2 stretches out from the first lockhole, scissors spring bolt 3 stretches out from the second lockhole to cooperate with the locked groove on the and door frame, lock.

Further, the method can also comprise the following steps: the locking block 4 is connected with the lock box 1 in a sliding mode, and in the locking state, the locking block 4 abuts against the scissors lock tongue 3 and can prevent the scissors lock tongue 3 in the extending state from retracting so as to lock the scissors lock tongue 3; a first unlocking shifting block 5 and a second unlocking shifting block 6; drive assembly 7 is connected with the equal transmission of first unblock shifting block 5, second unblock shifting block 6, and drive assembly 7 can drive the action of first unblock shifting block 5 to drive 2 withdrawal lock boxes 1 of main spring bolt, drive assembly 7 can also drive the action of second unblock shifting block 6, slide in lock boxes 1 with drive locking block 4, make locking block 4 break away from with scissors spring bolt 3 mutually.

Be different from prior art, the utility model provides an automatic lock body, its drive assembly 7 can also drive second unblock shifting block 6 synchronously and drive locking block 4 and carry out the displacement when driving first unblock shifting block 5 and unblock main bolt 2 to remove the locking to scissors spring bolt 3, can improve the degree of automation of lock body by a wide margin.

Moreover, the locking block 4 and the driving assembly 7 are only driven by the second unlocking shifting block 6, so that the transmission structure is simple, and the transmission efficiency is high; the scheme of sliding connection is adopted between the locking block 4 and the lock box 1, and the connection structure is simpler.

In detail, the driving assembly 7 may include a driving motor 71 and a first transmission gear 72, and the driving motor 71 may be in transmission connection with the first transmission gear 72; here, the embodiment of the present invention does not limit the transmission mode between the driving motor 71 and the first transmission gear 72, which may be direct transmission or indirect transmission, when a scheme of direct transmission is adopted, the first transmission gear 72 may be directly fixed in the rotating shaft of the driving motor 71, when a scheme of indirect transmission is adopted, one or more intermediate gears may be disposed between the driving motor 71 and the first transmission gear 72, so as to indirectly transmit the driving force of the driving motor 71, and through the transmission of multiple gears, the rotation speed of the first transmission gear 72 and the installation position of the first transmission gear 72 in the lock box 1 may be conveniently adjusted.

During the unblock, driving motor 71 can drive first unblock shifting block 5 through first drive gear 72 and rotate, and first unblock shifting block 5 can offset with the unblock recess 21 of main spring bolt 2 to drive main spring bolt 2 and withdraw lock box 1.

In one scheme, the first unlocking moving block 5 and the first transmission gear 72 may be fixedly connected, and at this time, the first unlocking moving block 5 and the first transmission gear 72 are equivalent to one component, and the two components can rotate synchronously.

In another scheme, referring to fig. 4, both the first transmission gear 72 and the first unlocking moving block 5 may be mounted on the first rotating shaft 51 and can rotate relatively, at this time, an axial end surface of the first transmission gear 72 may be provided with a first unlocking protrusion 721, and the first unlocking moving block 5 may include the first driving portion 52 and the first unlocking portion 53. When the first transmission gear 72 is driven to rotate, the first unlocking protrusion 721 can abut against the first driving portion 52 and drive the first unlocking moving block 5 to rotate, and then the first unlocking portion 53 can drive the main bolt 2 to retract into the lock box 1, where the state at this time can be referred to fig. 3.

In comparison, the number of parts of the first scheme can be small, the installation can be convenient, and the first transmission gear 72 and the first unlocking shifting block 5 can be simpler in structure because no transmission design is needed between the first transmission gear 72 and the first unlocking shifting block 5; in the second scheme, the first transmission gear 72 and the first unlocking shifting block 5 can rotate relatively, so that after the driving motor 71 drives the first unlocking shifting block 5 to unlock the main bolt 2, the state of the first unlocking shifting block 5 cannot be changed when the driving motor 71 automatically resets, and the situation that the main bolt 2 is driven to extend again to cause incapability of unlocking when the driving motor 71 automatically resets can be avoided. Of course, the above two schemes can both achieve the technical effect that the first unlocking moving block 5 unlocks the main bolt 2, and in specific implementation, a person skilled in the art can select the unlocking moving block according to actual needs.

The utility model provides an automatic lock body can also include control assembly 8, as shown in figure 8, control assembly 8 specifically can adopt PCB (Printed Circuit Board) subassembly, can be equipped with main spring bolt position detection switch 82 on it. When the main bolt 2 is in the extended or retracted state, i.e., the locked state, the main bolt position detection switch 82 may be in a closed or open state to transmit a lock signal or an unlock signal.

Specifically, as shown in fig. 5, the lock case 1 may be provided therein with a switch dial 9, the switch dial 9 may be hinged by a hinge shaft 91, and the switch dial 9 may include a first end 92 and a second end 93 at two sides of the hinge shaft 91, wherein the first end 92 may be connected with an elastic member 94, and the elastic member 94 may be an elastic element such as a spring, a tensile cord, or the like.

In the locked state, referring to fig. 1, the extended main bolt 2 may abut against the second end 93, the first end 92 may be pressed on the main bolt position detecting switch 82 to close the main bolt position detecting switch 82, and at this time, the elastic member 94 may be in a deformed state, and the deformed state of the elastic member 94, specifically, whether tensile deformation or compressive deformation, is related to the installation position of the elastic member 94, which is not limited herein.

In the unlocked state, the main bolt 2 can be retracted to disengage from the second end 93, and at this time, the elastic force gathered by the elastic member 94 can be released to force the switch moving block 9 to rotate, and the first end 92 can release the pressing of the main bolt position detecting switch 82, so that the main bolt position detecting switch 82 is turned off.

It should be noted that, in the above-mentioned solution, the main-bolt position detection switch 82 is pressed to represent closing and transmit the unlocking signal, and the main-bolt position detection switch 82 releases the pressing to represent opening and transmit the locking signal, actually, the main-bolt position detection switch 82 may represent opening when pressed, and further transmit the unlocking signal to the outside, that is, when the main-bolt position detection switch 82 is pressed, it may be in the closed state or in the open state, as long as it changes from the original state.

More specifically, the main bolt 2 may be provided with a protruding latch 22, and in the locked state, the main bolt 2 may abut against the second end 93 through the latch 22, and during unlocking, the main bolt 2 may retract into the lock case 1, so that the latch 22 may be staggered from the second end 93, and thus, the pressure acting on the second end 93 may disappear, and the switch shifting block 9 may smoothly rotate under the action of the elastic member 94.

It should be noted that the above scheme of triggering the main lock tongue position detection switch 82 by using the switch shifting block 9 is only an exemplary scheme of the embodiment of the present invention, and it cannot be taken as a limitation to the implementation range of the automatic lock body provided by the present invention, and under the condition that the function is satisfied, other schemes may be used to trigger the main lock tongue position detection switch 82; for example, the main bolt 2 can be directly used for triggering, and at this time, only the main bolt position detection switch 82 needs to be arranged on the action path of the main bolt 2, and when the scheme is adopted, the components such as the switch shifting block 9 and the like can be omitted, so that the positive effect on the structural simplification of the automatic lock body is achieved.

The driving assembly 7 may further include a second transmission gear 73, the second transmission gear 73 may be engaged with the first transmission gear 72, when the first transmission gear 72 rotates, the second transmission gear 73 may be driven to rotate, and then the second transmission gear 73 may drive the second unlocking shifting block 6 to rotate, and the second unlocking shifting block 6 may shift the locking block 4 to move.

Specifically, referring to fig. 6, an axial end surface of the second transmission gear 73 may be provided with a second unlocking protrusion 731, the second unlocking paddle 6 may be mounted on the second rotating shaft 61, and the second unlocking paddle 6 may include a second driving portion 62 and a second unlocking portion 63; when the second transmission gear 73 is driven to rotate, the second unlocking protrusion 731 can abut against the second driving portion 62 and can drive the second unlocking moving block 6 to rotate, and the second unlocking portion 63 can drive the locking block 4 to be separated from the scissors lock tongue 3.

As also shown in fig. 6, the second driving portion 62 and the second unlocking portion 63 may be disposed at an angle to adapt to the installation positions of the second transmission gear 73 and the locking block 4 in the lock box 1; moreover, the second driving portion 62 may also adopt a zigzag stepped design, wherein a zigzag upper cross plate may be located on the upper side of the second transmission gear 73 to cooperate with the second unlocking protrusion 731, and a zigzag lower cross plate may be lowered in its installation position to reduce the space occupied by the second unlocking moving block 6 in the axial direction of the second rotating shaft 61.

The second unlocking shifting block 6 can also be provided with a switch triggering part 64, the switch triggering part 64 can rotate along with the second unlocking shifting block 6, the control component 8 can also be provided with a scissors lock tongue unlocking in-place switch 81, when the second unlocking shifting block 6 drives the locking block 4 to be separated from the scissors lock tongue 3, the switch triggering part 64 can press the scissors lock tongue unlocking in-place switch 81 to enable the original state (originally closed or disconnected) of the scissors lock tongue unlocking in-place switch 81 to be changed, and then a signal that the scissors lock tongue 3 is unlocked in place can be transmitted.

In actual operation, the time for unlocking the scissor lock tongue 3 in place is not earlier than that of the main lock tongue 2, so that the situation that the automatic lock body cannot be opened due to the fact that the scissor lock tongue 3 is unlocked and the main lock tongue 2 cannot be unlocked in time can be avoided.

To this end, in the embodiment of the present invention, a hysteresis structure may be disposed on the transmission path between the driving motor 71 and the locking block 4, so that the locking block 4 does not completely separate from the scissor latch bolt 3 or completely separates from the scissor latch bolt 3 when the main latch bolt 2 is completely retracted, and the unlocking time of the scissor latch bolt 3 may not be earlier than the main latch bolt 2.

Specifically, the hysteresis structure described above may include: when the first unlocking moving block 5 is in an abutting state with the main bolt 2, that is, when the main bolt 2 is ready to be driven for unlocking, a circumferential gap may be formed between the second driving part 62 and the second unlocking protrusion 731, and/or between the second unlocking part 63 and the locking block 4, so that the unlocking of the scissors bolt 3 may lag behind the main bolt 2; and/or the diameter of the first transmission gear 72 can be designed to be smaller than that of the second transmission gear 73, so that the rotating speed of the second transmission gear 73 can be slower than that of the first transmission gear 72, and the unlocking time of the scissors lock tongue 3 can be delayed.

The control assembly 8 can also be provided with a locking block position detection switch 83, when the locking block 4 is in a position abutting against the scissors lock tongue 3 and capable of blocking the scissors lock tongue 3 from retracting, the locking block 4 can press the locking block position detection switch 83, so that the original state (originally closed or disconnected) of the locking block unlocking in-place switch 83 is changed, and then a signal that the locking block 4 is locked in place can be transmitted to reflect the locking condition of the scissors lock tongue 3.

In the above solution, the change of the state of the locking block position detection switch 83 is used to represent that the locking block 4 is locked in place, and actually, the change of the state of the locking block position detection switch 83 may also be used to represent that the locking block 4 is unlocked in place (i.e. the locking block 4 is separated from the scissors tongue 3), and only the installation position of the locking block position detection switch 83 needs to be adjusted.

It should be understood that, when the lock box 1 is installed, the first box plate attached to the door body, the second box plate opposite to the first box plate, and the circumferential box plate connecting the first box plate and the second box plate may be provided, where the circumferential box plate is a side wall of the lock box 1, that is, a portion where the first locking hole and the second locking hole are provided.

Referring to fig. 1 and 3 together, when the detecting tongue 10 is in the extended state, the push block 101 of the detecting tongue 10 can abut against one leg 41 of the locking block 4, and at this time, the locking block 4 is limited by the push block 101 at a position separated from the lock tongue 3 of the scissors, and the lock tongue 3 of the scissors is in a freely retractable state; when the detection tongue 10 is in a retracted state, the push block 101 can be separated from the locking block 4, the locking block 4 can move towards the scissors lock tongue 3 under the action of a torsion spring (not labeled in the figure), and when the scissors lock tongue 3 is in an extended state, the locking block 4 can abut against the rear end of the scissors lock tongue 3 to lock the scissors lock tongue 3.

The sliding portions 411 may be disposed at two ends of the supporting leg 41, at this time, for the locking block 4, there may be four sliding portions 411, and accordingly, both the first box plate and the second box plate of the lock box 1 may be provided with the sliding fit portion 11 to be matched with the four sliding portions 411, the matching manner here may be a one-to-one matching manner, that is, one sliding portion 411 is correspondingly provided with one sliding fit portion 11, such a matching manner may refer to fig. 2, or only one sliding fit portion 11 may be disposed on the same box plate, and two sliding portions 411 on the same side of the locking block 4 may be inserted into the same sliding fit portion 11. So set up, all can have two sliding part 411 between locking piece 4 and each box board, be more favorable to guaranteeing gliding direction.

It is understood that the number of the sliding portions 411 provided between the locking block 4 and the same cassette board is not limited to two, and may be three or more, and may be specifically set according to actual needs.

A bush 312 may be further disposed between the sliding portion 411 and the sliding fit portion 11, and the bush 312 may be specifically sleeved on the sliding portion 411 for reducing the wear between the sliding portion 411 and the sliding fit portion 11 and facilitating the reduction of noise. One support leg 41 of the locking block 4 may be provided with a switch trigger plate 43, and when the locking block 4 is located at a position blocking retraction of the scissor latch 3, the locking block unlocking switch 83 may be pressed through the switch trigger plate 43, or of course, the locking block unlocking switch 83 may be directly pressed through the support leg 41.
