Description

Technical Field

[0001] The present invention relates to the field of locks, and in particular to an electronic lock. Background Art

[0002] Electronic locks are electronic products that control the operation of circuits or chips (access control systems) through inputs such as passwords, fingerprints, and remote controls, thereby controlling the closing of mechanical switches to complete unlocking or locking tasks. Electronic locks are widely used in residences, hotels, guesthouses, apartments, villas, and other places. Users do not need to carry keys, and they are easy to use.

[0003] Traditional electronic locks require openings on the panel to allow for the placement of the keyboard and battery, which makes it easier to operate the keyboard and remove the battery, and then cover the keyboard with a sliding cover (or the keyboard directly). Since the mechanical strength of the keyboard and battery parts is lower than that of other parts of the lock, criminals can destroy the keyboard by violence, and then destroy the lock, which poses a great safety hazard. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an electronic lock which can prevent violent disassembly.

[0009] Optionally, hollow slots are provided on both sides of the extraction component. The first positioning member is a cylinder which is fixed in the guide groove and sleeved in the slot. One end of the torsion spring is sleeved on the cylinder. When the extraction component slides, the slot slides along the cylinder.

[0010] Optionally, guide rails are provided on both sides of the extraction component, and the width of the guide rails is adapted to the guide groove. Guide bars are provided on the inner side walls of the guide rails, the slots are arranged on the guide bars, the cylinder is a positioning screw, and the housing includes a bottom plate opposite to the panel. The positioning screw passes through the bottom plate and the slot and is fixed in the guide groove.

[0011] Optionally, a first circuit board is provided in the housing, and a second circuit board is provided on the extraction component. The first circuit board and the second circuit board are connected by a flexible circuit. Mounting posts for connecting to another housing are provided on the inner surface of the panel.

[0017] Further, the extraction component slides out of the housing in a rotating manner.

[0018] In this application, the keyboard component or the battery component is fixed on the extraction component, and the extraction component is embedded into the interior of the housing. When in use, the extraction component slides out from the opening of the frame, allowing the user to operate the keyboard or replace the battery. After use, the extraction component is slid back into the interior of the housing.

Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, "multiple" means two or more. In addition, the term "including" and any variation thereof are intended to cover non-exclusive inclusions.

[0035] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0036] The terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments. Unless the context clearly indicates otherwise, the singular forms "one", "one" and "item" used herein are also intended to include plural numbers. It should also be understood that the terms "include" and / or "comprise" used herein specify the existence of stated features, integers, steps, operations, units and / or components, without excluding the existence or addition of one or more other features, integers, steps, operations, units, components and / or combinations thereof.

[0037] The present application discloses an electronic lock. The electronic lock comprises two shells, at least one of which comprises a panel, a frame and a pull-out component, the panel is provided with a handle; the frame is arranged around the panel; the pull-out component is located in the shell; a keyboard assembly or a battery assembly is arranged in the pull-out component, the frame is provided with an opening; the pull-out component slides out from the opening; the panel area corresponding to the pull-out component is made of metal material and is fixedly connected to the frame.

[0038] In this application, the keyboard assembly or battery assembly is fixed on the pull-out component, and the pull-out component is embedded in the shell. When in use, the pull-out component slides out from the opening of the frame, and the user can operate the keyboard or replace the battery. After use, the pull-out component is slid back into the shell. This method does not require an opening on the panel, so that the panel area corresponding to the pull-out component can be made of a whole piece of metal material and fixedly connected to the frame, thereby improving the overall mechanical strength of the key or battery area and effectively preventing violent damage by lawbreakers.

[0039] For electronic locks with fingerprint, remote control and other unlocking methods, even if the keyboard or battery is violently damaged, it can still be unlocked through these methods. Since the keyboard or battery is movable, there is no need to drill holes in the corresponding surface shell, thereby improving the consistency of the surface shell appearance.

[0040] Furthermore, the panel and the frame can be integrally formed of metal materials. Using a complete piece of metal plate can achieve smoke and fire prevention, improve high temperature resistance, enhance mechanical strength, further improve the safety performance of the lock, and maintain the simplicity and consistency of the panel, which is in line with the aesthetic concepts of the mainstream public.

[0041] The extraction component can be driven by an electric device, a pneumatic device or a hydraulic drive device. Of course, for the sake of simplifying the structure and reducing costs, it can also be driven manually.

[0042] The extraction component can be translated and slide out in a straight line, or it can be rotated and slide out in an arc surface. The frame has four sides, namely the upper, lower, left and right sides, and the opening can be on any side.

[0043] Taking the manual drive mode as an example, and the extraction component slides out from the top of the frame in a translational manner, the present invention will be further described below.

[0044] The electronic lock includes two housings. One housing is fixed on the outdoor surface of the door, and a keyboard assembly is provided inside the housing. The other housing is fixed on the indoor surface of the door, and a battery assembly is provided inside the housing. The inventive concept of the present application is applicable to both the keyboard assembly and the battery assembly.

[0045] Refer to Figure 1-12 , the housing 10 includes a panel 11 and a frame 12 surrounding the panel. An extraction component 13 is provided inside the housing. A keyboard assembly 15 or a battery assembly 16 is fixed on the extraction component. A handle 17 is provided on the panel. Side walls 20 are provided at both sides of the frame, and an opening 14 is provided at the top of the frame. A guiding structure, specifically a guide groove 21, is provided on the inner surface of the side wall. Correspondingly, guide rails 22 are provided on both sides of the extraction component. The width of the guide rail is adapted to the guide groove, and the guide rail slides along the guide groove. Of course, in the present application, the side walls of the frame can also be set as guide rails, and the extraction component is correspondingly provided with guide grooves.

[0046] The housing is fixed to the door. One side at both sides corresponds to the handle, and the other side corresponds to the door frame. If it slides out from the side, either the handle will get in the way and it is not convenient to operate, or the door frame part may cause interference and affect the sliding out. Generally, there is no interference in the up and down positions. When popping out from the top, the height of the keyboard is relatively appropriate, which is convenient for users to operate. Moreover, the handle of the lock is generally located below the panel, and there is generally a keyhole 18 of the mechanical lock below the handle. This makes the space in the lower area of the panel relatively small, and it is more difficult to make the extraction component inside. The space above the panel is sufficient, which is convenient for implementation.

[0047] The cooperation of the guide rail and the guide groove enables the extraction component to slide out in a translational manner in a straight line. Because of the positioning of the guide grooves on both sides, this sliding out method has high support strength. When the user operates the keys, the keyboard is relatively stable and will not shake.

[0048] The extraction component of this embodiment slides out manually. Combining Figure 9 and 10As shown, two torsion springs 27 are provided in the housing, and a first positioning member is provided in each of the two guide grooves. The first positioning member is in the form of a column, and specifically, a positioning screw 25 can be selected. The extraction component is provided with a second positioning member corresponding to the first positioning member, and the second positioning member is a fixing column 26. One end of the torsion spring is fixed on the fixing screw; the other end of the torsion spring is fixed on the fixing column, and the center of the torsion spring is located within the stroke range of the extraction component.

[0049] The inner wall of the guide rail is provided with a guide bar 23, and a hollow slot 24 is provided on the guide bar. The housing includes a bottom plate 19 opposite to the panel, and a positioning screw passes through the bottom plate and the slot and is fixed in the guide slot. When the extraction component slides, the slot slides along the positioning screw.

[0050] The positioning screw can not only fix the bottom plate, but also cooperate with the slot to limit the sliding stroke of the pull-out part, and can also be used to fix the torsion spring, achieving three goals at one stroke and being simple to implement. The slot is a strip-shaped closed loop structure. Once the positioning screw is installed, the pull-out part can be locked within the stroke range to avoid human-induced violent extraction, thus improving safety performance.

[0051] A torsion spring is used, and the center of the torsion spring is within the travel range of the pull-out component. When the pull-out component is pulled upwards beyond the center position, the two end arms of the torsion spring tilt upwards, and under the action of elastic stress, the pull-out component pops out faster. Since the housing is provided with a positioning screw, when the keyboard slides out to the upper limit position, it cannot continue to slide. At the same time, under the elastic action of the torsion spring, the keyboard will not actively fall down when the hand is released, so that the pull-out component is maintained at the upper limit position. Similarly, when the pull-out component is pressed downwards beyond the center position, the two end arms of the torsion spring tilt downwards, and under the action of elastic stress, the pull-out component falls back faster. Since the housing is provided with a positioning screw, when the keyboard slides out to the upper limit position, it cannot continue to slide. At the same time, under the dual action of the elastic action of the torsion spring and the gravity of the pull-out component, the pull-out component can be maintained at the lower limit position.

[0052] The guide bar is arranged on the inner wall of the guide rail, and is at a distance from the upper and lower surfaces of the shell, forming a hollow avoidance space. When the circuit board area of the electronic lock is large, the circuit board can be embedded in the avoidance space when the components are pulled out and stored, avoiding mutual interference and saving the internal space of the shell.

[0053] In order to adapt to the pull-out structure of the present application, the inventor has also made corresponding improvements to the circuit structure.

[0054] First, the original integrated circuit board is split into a first circuit board 30 fixed in the housing and a second circuit board 31 fixed in the drawer. The first circuit board and the second circuit board are connected via a flexible circuit such as a wire 32.

[0055] Inside the housing where the keyboard assembly is located, the first circuit board corresponds to the main control circuit, which is responsible for collecting and analyzing various data and controlling the opening and closing of the lock; the second circuit board corresponds to the keyboard control circuit. Since the keyboard assembly will be exposed after the extraction component is pulled out, even if the second circuit board is damaged, it will not affect the function of the first circuit board, which is safe and reliable. In particular, existing electronic locks generally have a fingerprint unlocking function, and the keyboard is only auxiliary. The fingerprint module is directly connected to the main control circuit, so even if the keyboard is damaged, it will not affect the fingerprint unlocking function, and the lock can be used normally.

[0056] Inside the housing where the battery assembly is located, the first circuit board corresponds to the transfer circuit and is connected to the main control circuit of another housing, and the second circuit board corresponds to the connection and management circuit related to the battery. And this part of the housing is indoors and cannot be damaged from the outside, so it is generally not easily damaged.

[0057] There are multiple wires, which can adopt a flexible cable structure or an independent non-flexible cable structure. In this application, the number of connections between the two circuit boards is not large, and a non-flexible cable structure can be considered. At this time, the interfaces where the first circuit board and the second circuit board are connected are arranged in a horizontal offset. Since they are offset in the horizontal direction, during the pulling process of the extraction component, the wires will not be vertically folded, avoiding wire breakage after multiple pulls and improving the service life of the wires.

[0058] Furthermore, the inner surface of the panel is provided with mounting posts 28 connected to another housing; the extraction component is provided with avoidance notches 45 corresponding to the mounting posts; the first circuit board is arranged between the mounting posts and the handle. After dividing the circuit board into two parts, the components of the corresponding first circuit board are reduced. Especially in the housing where the battery assembly is located, the first circuit board is a transfer board, and its area can be optimized and reduced. It can be placed between the mounting posts and the handle. In this way, the distance from the extraction component is close, and the connecting wires can be shortened; and it will not interfere with the sliding of the sliding component.

[0059] Since the keyboard only needs to work when it is pulled out, if it is always in the working state, it will undoubtedly cause power consumption. Therefore, in this application, the body of the position sensor is arranged on the first circuit board, and the sensing end of the position sensor is correspondingly arranged on the extraction component. The body of the position sensor selects a Hall switch 33, and a magnet 34 is attached to the corresponding position of the extraction component guide rail. During the pulling process, the magnet will pass by the Hall switch. When the keyboard is pulled to the upper limit, the magnet approaches the Hall switch, and the keyboard is automatically started. When the keyboard slides into the housing, the magnet moves away from the Hall switch, and the keyboard is automatically turned off. By integrating the Hall switch into the first circuit board, there is no need to add an additional sensor circuit board.

[0060] Figure 11The figure shows a schematic diagram of a pull-out component of a corresponding keyboard assembly. The pull-out component is made of a metal frame as a whole. A top cover 42 is provided on the top to cover the opening. A handle structure is provided on both sides of the top cover to facilitate the pull-out of the component by hand. The specific structure is a convex piece 43, which protrudes from both sides of the top cover to facilitate the hooking of fingers. The upper part of the frame is hollowed out as a whole, and the keyboard and the second circuit board are installed. A partition 41 is provided in the middle of the lower part. The bottom of the partition is provided with the above-mentioned avoidance gap 45. The part adjacent to the keyboard is provided with a through hole 39. The wire passes through the through hole 39 to connect the first circuit board and the second circuit board respectively. A second positioning member is provided on the side of the partition opposite to the keyboard. The specific structure is a fixed column 26. The fixed column is located on both sides of the top of the gap. One end of the torsion spring is respectively sleeved on the fixed column and can rotate around the axis of the fixed column. Then there is a cover plate 40 on it to cover the back of the pull-out component as a whole, and to seal the torsion spring and the second circuit board. There is a threaded hole in the fixed column. The cover plate is fixed in the fixed column by screws. After the torsion spring is sealed by the cover plate, it is confined to the fixed column and will not fall off.

[0061] Figure 12 The figure shows the corresponding battery assembly extraction part schematic diagram. The frame structure is basically the same as the keyboard assembly extraction part, but the battery assembly is located behind the door, so there is no need to worry about external damage. It can be made of plastic material to reduce costs. If wireless communication is required, it is necessary to attach an antenna 35. Plastic material will not shield the signal. The antenna 35 can be attached to the inner surface of the top cover 42.

[0062] The side frame of the pull-out component of this part is provided with a switch hole 46, corresponding to the key switch 36, which is used to set the lock, such as adding and deleting fingerprints, passwords, etc.

[0063] The manual drive mode of the extraction component can also have other structural forms, as shown below.

[0064] Alternative method 1: a first limiting structure and a second limiting structure are set at corresponding positions of the guide groove; the pull-out component is stopped at the first position by the first limiting structure in the storage state; and the pull-out component is stopped at the second position by the second limiting structure in the sliding state.

[0065] Alternative method 2: Add an elastic structure on the basis of the above alternative method, replace the first limiting structure with a positioning structure, in the stored state, the positioning structure limits the pull-out component to the first position, the elastic structure is in contact with the pull-out component, and the elastic structure is in an energy storage state; in the sliding state, the positioning structure is out of contact with the pull-out component, and the pull-out component is ejected by the action of the elastic structure, so that it stays in the second position.

[0066] As another embodiment of the present invention, the electronic lock comprises an electric device, a pneumatic device or a hydraulic drive device for driving the withdrawing component.

[0067] The above is a further detailed description of the present invention in conjunction with specific preferred embodiments. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should all be regarded as belonging to the protection scope of the present invention.
