Intelligent lock handle structure

Abstract

An intelligent lock handle structure comprises a lock shell and a handle transmission mechanism, wherein a handle connecting hole is formed in a bottom plate or a cover plate of the lock shell, and the handle transmission mechanism is arranged in an inner cavity of the lock shell. The power input end of the handle transmission mechanism is connected with a handle through the handle connecting hole. The distance between the center of the handle connecting hole and the locking side edge of a spring bolt of the door leaf is larger than 70 mm to 110 mm. According to the technical scheme, due to the fact that the distance between the handle and the door leaf is larger when the door leaf is opened and closed, the safety risk that the hand is collided or clamped when the handle is held by a hand to push and pull the door can be avoided.

Description

Technical Field

[0001] This utility model relates to the field of lock technology, specifically to the handle structure of a smart lock. Background Technology

[0002] The smart lock industry is developing rapidly, and most smart lock designs have abandoned the traditional horizontal handle, favoring vertical handles and integrated handles. Traditional door locks, due to their horizontal handle placement near the door frame when closing, are designed to be compact, thus subjectively placed as close to the door edge as possible. Changing this to a vertical or integrated handle results in the user's hand being closer to the door frame when gripping the handle. Therefore, most smart lock manufacturers on the market still standardly use a traditional 60mm lock body edge distance. Figure 1 , 2 As shown, for a standard-sized smart lock handle, when configured with a universal small-lock body (the handle, keyhole, safety knob center, mounting screw holes need to be aligned with the lock body's handle hole, lock cylinder, safety knob hole, and mounting screw through hole), the distance between the handle and the door frame overlap is very small. This results in the smart lock being installed with the handle very close to the door edge. Most adult fingers are 15mm to 25mm thick, and even children capable of unlocking have fingers that are 10mm to 15mm thick. Figure 1 , 2 Taking the handle as an example, when opening and closing the door by gripping the handle from the right side of the diagram, there is a risk of the hand being pinched if the fingers extend to the left side of the handle. When opening and closing the door by gripping the handle from the left side of the diagram, the fingers or back of the hand will inevitably hit the overlapping part of the door frame. Thus, it is unavoidable that users will face the safety risk of their hands being hit or pinched when pushing and pulling the door. Summary of the Invention

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the problem that the hand pulling the handle is easily hit by the door frame when closing the door in the existing smart lock handle structure.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: an intelligent lock handle structure, comprising:

[0005] The lock housing has a handle connection hole on its bottom plate or the cover plate;

[0006] The handle transmission mechanism is located in the internal cavity of the lock housing, and its power input end is connected to the handle handle through the handle connection hole.

[0007] The distance between the center of the rotation shaft of the power input end and the locking edge of the door latch is greater than 70 mm and between 110 mm.

[0008] Preferably, the rotation axis of the power input end is 80mm away from the locking side edge of the door leaf.

[0009] Further, the lock core mounting hole and the knob center in the safety device are vertically aligned with the handle connecting hole.

[0010] Further, the lock core unlocking mechanism, the handle unlocking mechanism and the safety locking mechanism are arranged corresponding to the handle connecting hole based on the original positional relationship, connection relationship and interaction relationship.

[0011] The utility model discloses technical scheme, because handle handle has greater spacing between the overlap part of door frame when opening and closing door leaf, can avoid the safety risk of being hit hand or hand when holding handle and pushing and pulling door.

[0019] Exemplary embodiments of the present disclosure will be described below in greater detail with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be accurately conveyed to those skilled in the art.

[0020] Referring to Figure 3 、 4 The utility model discloses a kind of intelligent lock handle structure, including the lock shell 2 that handle connecting hole 1 is opened in bottom plate or the cover plate and the handle transmission mechanism 3 being set in the cavity in the lock shell 2. The power input end of the handle transmission mechanism 3 is connected handle handle 4 by the handle connecting hole 1.Wherein the distance between the rotation axis center of the power input end and the lock bolt locking side edge of door leaf 5 is between 70 millimeters to 110 millimeters.In the embodiment, the distance between the rotation axis center of the power input end and the lock bolt locking side edge of door leaf 5 is 80 millimeters.The distance of handrail and door frame 6 overlap part when opening and closing door has far exceeded the thickness of normal human finger, can effectively avoid the risk of being hit hand when hand opening and closing door.

[0021] In order to keep the neat appearance of door face, lock cylinder mounting hole and the knob center of safety assembly are vertically aligned with the handle connecting hole 1.The distance between the center of handle connecting hole 1 and the lock bolt locking side edge of door leaf 5 is increased, so it is needed to offset the relative position of handle connecting hole 1, lock cylinder mounting hole, handle assembly screw via hole and safety assembly to the opposite direction of lock bolt assembly locking direction.This involves corresponding changes of lock cylinder unlocking mechanism, handle unlocking mechanism and safety locking mechanism, and also can cause the size of lock shell to increase.

[0022] In order to still possibly apply previous prior art tooling die when adopting the technical scheme of the utility model, the most simple implementation mode is: offsetting lock cylinder unlocking mechanism, handle unlocking mechanism and safety locking mechanism to the direction away from the locking side edge of door leaf 5, and correspondingly widening lock shell.Lock cylinder unlocking mechanism, handle unlocking mechanism and safety locking mechanism in the embodiment are set on the basis that the previous position relationship, connection relationship and mutual action relationship among them remain unchanged.

[0023] Obviously, the above embodiment is only an example for clearly illustrating, not the limitation of implementation mode.Ordinary skilled in the art can make other different forms of changes or changes on the basis of the above description.Here, all implementation modes need not and cannot be exhausted.The obvious changes or changes derived from it are still within the protection scope of the utility model creation.
