The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.

As shown in fig. 1 and 2, the present invention discloses an intelligent lock with emergency knob 7, which comprises a panel base 1 installed on the door; the power device 2 is accommodated in the panel base 1; the emergency device 3 is connected with the power device 2 and is arranged on the panel base 1; a handle panel 8 which covers the panel base 1; a lining member 9 mounted on the surface of the handle panel 8; a cover 10 covers the surface of the lining element 9 and covers the emergency device 3.

As shown in fig. 2, the panel base 1 is recessed to form an accommodating space (not shown), the accommodating space (not shown) accommodates the power device 2, the power device 2 includes a motor 21 and a reducer 22 connected to the motor 21, the reducer 22 has a gear 221, a through hole 222 is formed through the middle of the gear 221, and at least one notch 2221 is formed on the surface of the through hole 222.

As shown in fig. 2 to 6, the emergency device 3 includes a rotating shaft 3, the rotating shaft 3 passes through the through hole 222, and an opening direction of the notch 2221 is consistent with an axial direction of the rotating shaft 3. Further, a step 311 is disposed on the surface of the rotating shaft 3, the surface of the step 311 faces the notch 2221 in the axial direction of the rotating shaft 3 and extends to form two protrusions 312, and the protrusions 312 are inserted into the notch 2221, so that the gear 221 can drive the rotating shaft 3 to rotate when rotating. The surface of the rotating shaft 3 is further recessed to form four clamping grooves 313 which are arranged in a central symmetry manner, the four clamping grooves 313 extend to the end part of the rotating shaft 3, and the two clamping grooves 313 are respectively opposite to the two protruding blocks 312, so that the structural rigidity of the rotating shaft 3 is increased.

A spacing dish 4, spacing dish 4 has a bottom surface 41, bottom surface 41 center is run through and is equipped with a round hole 42, pivot 3 passes round hole 42 makes spacing dish 4 cover is located in the pivot 3, a first lateral wall 43 certainly the edge of bottom surface 41 extends and forms, first lateral wall 43 is to being close to bottom surface 41 central direction extends and forms a plurality of barriers, and a plurality of barriers combination forms drive division 44, a second lateral wall 45 certainly the edge of round hole 42 extends to the direction that deviates from first lateral wall 43 and forms, second lateral wall 45 to round hole 42 central direction extends and forms four fixture blocks 46 of central symmetry, four the card is fast respectively held four the draw-in groove 313, makes pivot 3 with spacing dish 4 keeps synchronous revolution. A washer 5 is sleeved on the rotating shaft 3 and covers the driving part 44, and an elastic member 6 is sleeved on the rotating shaft 3, and two ends of the elastic member respectively support against the limiting disc 4 and the washer 5, so that the elastic member 6 is clamped and fixed between the limiting disc 4 and the washer 5. In this embodiment, the elastic element 6 is a spring sleeved on the rotating shaft 3, and in other embodiments, the elastic element 6 may be any other elastic object as long as it can elastically abut against the limiting disc 4 and the gasket 5, which is not limited herein. A clamp spring 51 is clamped on the rotating shaft 3 and blocks the washer 5, so as to prevent the washer 5 from being separated from the rotating shaft 3 due to the elasticity of the elastic member 6. A rubber ring 52 is disposed around the outer surface of the second sidewall 45.

A knob 7 located on one side of the washer 5, the knob 7 having a main body 71, the main body 71 being embedded in the handle panel 8 to limit the handle panel 8 from swinging, an operation portion 72 extending from one side of the main body 71 being exposed outside the handle panel 8, the operation portion 72 being held by an operator to rotate the knob 7, eight protruding columns extending from the other side opposite to the main body 71 to form an embedded portion 73, the embedded portion 73 facing the driving portion 44, and when the knob 7 is pressed down, the embedded portion 73 being capable of being engaged with the driving portion 44. Further, the main body 71 is circular, and the embedded portions 73 are uniformly distributed on the main body 71 and are centrosymmetric, so that the acting force of the knob 7 and the limiting disc 4 is uniform and stable. In addition, the knob 7 extends towards the direction close to the limiting disc 4 to form two positioning columns 74, and the positioning columns 74 extend to the clamping grooves 313 for positioning and installing the knob 7.

In this embodiment, the cover 10 covers the knob 7, so as to prevent the knob 7 from being exposed, increase the appearance consistency of the whole product, and enhance the market competitiveness of the product.

In the using process of the emergency device 3, the sealing cover 10 is taken down, the knob 7 is pressed to move, the rotating shaft 3 is driven to move, the projection 312 is separated from the notch 2221, the embedding part 73 is meshed with the driving part 44, and then the knob 7 is rotated to drive the limiting disc 4 to further drive the rotating shaft 3 to rotate; because the gasket 5 is positioned between the rotary part and the elastic part 6, the elastic part 6 cannot directly contact the knob 7, and therefore, when the power device 2 rotates, the rotary part cannot rub the elastic part 6, the running resistance of the motor is reduced, the service life of the intelligent lock is prolonged, and meanwhile, the risk that the appearance coating of the side wall of the knob 7 and the panel around the knob hole is abraded and damaged is reduced.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
