It is particularly preferred that the exterior surfaces of the engaged battery compartment assembly 60 and the exterior surfaces of the housing 41 and the closure plate 42, respectively, substantially match in alignment, and that the dimensions and shapes of the exterior surfaces of the components are continuously transitioned, as shown particularly in fig. 2.

In addition, the outer surface of the closing plate 42 has an inner recess 424, and the inner recess 424 is disposed opposite to the control plate 50 in the axial direction of the lock body shaft; and a rotating click plate 71 and a fitting plate 72 for facilitating the assembling operation are provided at the position of the inner concave portion 422. Further comprising:

For example, but not limited to, an arc-shaped hole 711 is formed in the rotating snap-in plate 71, which is concentric with the lock body shaft, and accordingly, the screw 425 penetrating through the arc-shaped hole 711 is screwed and fixed to the sealing plate 42, on one hand, the head of the screw 425 and the body of the rotating snap-in plate 71 beside the arc-shaped hole 711 constitute the above-mentioned axial limit fitting pair, and at the same time, the rotation amplitude of the rod of the screw 425 in the arc-shaped hole 711 meets the rotation stroke requirement of the switching of the working position.

The fitting plate 72 is fitted to the outside of the rotating click plate 71, has an axial engagement fitting portion with the rotating click plate 71, and is configured to: when the rotary buckle plate 71 is positioned at the assembling working position, the axial clamping adapting part forms axial limiting, and the lock body assembling is completed; when the rotary buckle plate 71 is located at the disassembly working position, the axial clamping adaptive part can be separated, and the disassembly operation can be carried out according to actual needs.

Correspondingly, a connecting piece 32 used for connecting with the lock body shaft is connected with the transmission piece 31 at one end and rotates synchronously; the other end of the connecting member 32 extends out of the assembly plate 72 to drive the lock body shaft to transmit, that is, the connecting member 31 sequentially passes through the middle assembly process holes of the control plate 50, the closing plate 42, the rotating snap-in plate 71 and the assembly plate 72 to pass through, so as to construct a transmission chain of the intelligent door lock and a transmission connection between the lock body shafts.

It should be understood that the "axial snap-fit adapter" between the mounting plate 72 and the rotating snap-fit plate 71 can be selected from different adapter structures according to the product mounting space and the process implementation manner. Such as but not limited to the mating structures preferably shown in the figures.

As shown in the figure, the outer edge of the rotation buckle plate 71 for embedding the mounting plate 72 has a second stop block 712 formed to extend radially inward, and accordingly, the mounting plate 72 is provided with a second engaging block 721, and the side of the second engaging block 721 is provided with a through third slot 722. When the two are assembled, the second stopping block 712 of the rotating snap-fit plate 71 passes through the third notch 722 of the assembling plate 72 to the upper side of the second engaging block 721, and then relatively rotates and moves to the position right above the second engaging block 721, i.e. the assembling position, and the axial snap-fit adapting portion forms an axial limit, thereby realizing the rapid assembly of the assembling plate 72. When the clamping device is disassembled, the rotating clamping plate 71 is rotated in the reverse operation mode until the disassembling operation is completed, and the clamping device has good operability. As shown in fig. 2 in particular, after the assembly, the size shape of each component surface passes through in succession, and is whole, the utility model provides an intelligence lock all has good integrated level in each dimension.

In addition, the connecting member 32 has a step limiting surface larger than the assembly process hole of the assembly plate 72 so as to form an axial limitation on the connecting member 32 after the assembly of the assembly plate 72 is completed, thereby completely avoiding the abnormal detachment of the connecting member 32 from the lock body.

In the present embodiment, the driving component of the transmission system 10 preferably adopts the motor 11, and is integrated with the gear reduction mechanism 12, the clutch mechanism and the transmission member 31 in the box 13 of the transmission system 10, so as to improve the integration level and the assembly manufacturability of the whole machine. Preferably, the gear reduction mechanism 12 is a spur gear transmission mechanism. On one hand, the integration level is better, the assembly operation of the whole machine is convenient, and the assembly manufacturability is better; in addition, the gear reduction mechanism is preferably a straight-tooth transmission mechanism, so that the space occupation along the axial direction of the shaft body shaft can be greatly reduced, and the gear reduction mechanism can be widely applied to the use environment with strict requirements on the overall dimension in the thickness direction.

The output shaft of the driving motor 11 is in transmission connection with the gear reduction mechanism 12, and it can be understood that the final driven wheel 121 of the gear reduction mechanism 12 is the final gear for constructing the clutch mechanism, please refer to fig. 3, which shows a schematic view of the assembly relationship of the clutch mechanism according to the present embodiment.

As mentioned above, the driving member and the manual knob of the smart door lock can respectively drive the lock body shaft (not shown in the figure) to rotate through the transmission member 31, and specifically, the transmission member 31 is provided with the output gear 311 which coaxially rotates to transmit power with the transmission chain. Referring to fig. 4, a main body structure of the clutch mechanism according to the present embodiment is shown.

In this embodiment, a planetary transmission assembly 80 is disposed between the output gear 311 and the final stage gear (the final stage driven wheel 121) in transmission connection with the output shaft 111 of the driving member, and the planetary transmission assembly 80 includes a sun gear 81, a planet carrier 82, and two planet gears: a first planet 831 and a second planet 832.

The sun gear 81 is engaged with the final driven gear 121, and the planet carrier 82 and the sun gear 81 are coaxially and fixedly arranged; two planetary gears rotatably provided on the carrier 82 are respectively located on both sides of a line connecting rotational centers of the sun gear 81 and the output gear 311, and have two meshing relationships respectively corresponding to the opening and closing. The concrete configuration is as follows: when the planet carrier 82 rotates clockwise, the first planet wheel 831 can form a first meshing relationship with the output gear 311, as shown in fig. 5; when the planet carrier 82 rotates in the reverse direction, the second planet gears 832 may be in a second meshing relationship with the output gear 311, as shown in fig. 6.

Wherein carrier 82 has a transitional rotational travel that switches between the first and second meshing relationships. It should be noted that the "transition rotation stroke" is a specific rotation stroke for switching from one engagement relationship to another engagement relationship, and is substantially in a disengaged state for constructing the clutch mechanism, specifically, a schematic diagram of the disengaged state shown in fig. 7.

The scheme is that a clutch mechanism is arranged between a transmission piece 31 which drives a lock body shaft to rotate and an automatic driven final-stage driven wheel 121, and two driving meshing relations are utilized to respectively correspond to automatic unlocking and locking operations. Meanwhile, based on the setting of the transitional rotation stroke, the driving part and the transmission part can be ensured to be separated, and the first meshing relation and the second meshing relation are in a non-transmission connection state, so that the automatic driving side component of the clutch mechanism can be reliably separated from the transmission part. In practical application, the manual unlocking operation can be realized without applying large acting force, and on the basis of greatly improving user experience, a good technical guarantee is provided for ensuring the conversion of manual and automatic operation.

As shown, the planet carrier 82 includes a first plate 821 and a second plate 822 spaced apart from each other, and two planet gears are disposed between the first plate 81 and the second plate 82. The sun gear 81 is fixedly connected with the second plate 822 of the planet carrier 82 and is located in the box body 13, so that the overall space utilization rate is better. Preferably, carrier 82 is in an intermediate position between the first and second meshing relationships in a normal state, and the automatic drive side member of the clutch mechanism and the transmission are in a non-transmission connected state. That is, this intelligent lock has good manual operation experience under the normality.

In order to obtain good manual and automatic operation switching performance, a detection means for rotating the working position can be further added. As shown in fig. 8, a switch knob 91 may be provided on the planet carrier 82, and accordingly, a detection switch 92 may be further included, and the detection switch 92 may be provided on the control board 50 to further improve the utilization of the internal space. Wherein the switch knob 91 is configured to: when the planet carrier 82 rotates to form the first engagement relation and the second engagement relation, the detection switches 92 can be triggered to form corresponding trigger signals, and the trigger signals are output to the control board 50. Based on this, the control board 50 can output the reverse rotation control signal according to the corresponding trigger signal so that the carrier 82 is at the intermediate position.

Taking the example that the planet carrier 82 rotates clockwise to form the first meshing relationship for automatic unlocking, under the driving of the driving motor 11, when the planet carrier 82 rotates clockwise to complete unlocking, after the detection switch 92 is triggered, the control board 50 outputs a reverse rotation control signal to the driving motor 11, and the planet carrier 82 rotates counterclockwise to an intermediate position, that is, both planet wheels process a non-meshing state. And vice versa. Therefore, the intelligent door lock can be always kept in a normal working position which can be manually operated at any time after the locking and unlocking operation is automatically driven.

In addition, the control board 50 may detect the actual rotation angle of the lock body shaft in real time according to the timing at which the detection switch 92 is actually triggered, so as to perform feedback adjustment.

In addition, the control board 50 may obtain a result of determining that the clutch mechanism is in the disengaged state without receiving the trigger signal, and output a command signal that can be manually operated. That is, the control strategy can be optimized on the basis, the judgment result that the clutch mechanism is in the separation state is further obtained, and the command signal capable of being manually operated is output, that is, the detection switch 92 is not triggered when the clutch is separated, so that the electric and manual switching can be reliably realized. For example, but not limited to, the method of using sound and light prompts, so that the operator can accurately grasp the manual operation timing.

It should be noted that the above-mentioned embodiment is not limited to the power transmission by the spur gear speed reduction mechanism 12 shown in the drawings, and it should be understood that the core concept is consistent with the present disclosure and is within the scope of the present application. In addition, the selection of the switch type and the specific control strategy can be realized based on the prior art, and therefore, the detailed description is omitted here.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that it is obvious to those skilled in the art that various modifications and improvements can be made without departing from the principle of the present invention, and these modifications and improvements should also be considered as the protection scope of the present invention.
