Description

Technical Field

[0001] The present invention relates to the technical field related to locks, and in particular to a lock handle with a double-layer structure and a lock using the same. Background Art

[0002] In order to facilitate operation, lock products are generally equipped with handles. In order to improve the structural strength of the handles, common handles are generally cast from aluminum alloys. However, due to the limitations of metal casting technology, in order to allow the molten metal to fill the cavity, the wall thickness of the casting is generally set to be relatively thick. For example, the minimum wall thickness of aluminum alloy castings is generally not less than 2mm~5mm, which makes the weight of the cast handle parts heavier, which greatly increases the manufacturing and transportation costs. Moreover, the surface of the cast handle blank parts is very rough. During production, the surface of the blank parts needs to be polished, polished and electroplated many times, and the processing is very cumbersome. In addition, bubbles are inevitably formed inside the casting parts. If bubbles are formed on the surface of the casting, they cannot be repaired by general polishing processes and can only be scrapped, which increases the production loss rate of the casting parts and increases the manufacturing cost. In addition, for smart locks, electrical components and moving parts are placed inside the handles. Generally, the internal parts are protected by combining the handle cover with the cast handle parts. However, since the edges of the cast parts are uneven during molding and difficult to control, a large gap will be generated when the handle cover is combined with the cast handle parts. External liquid and water vapor can easily enter the handle and cause short circuits in the electrical parts. Therefore, how to improve the surface aesthetics of the handle parts, reduce the overall weight and manufacturing cost of the parts, and improve the stability of use have become urgent issues to be solved in the production of lock handle products. Summary of the invention

[0003] In order to overcome at least one of the above-mentioned problems existing in the lock handle in the prior art, the present invention proposes a double-layer lock handle, including a handle embedded module and an outer shell, the handle embedded module includes a base and a handle panel, the base includes a base bottom plate and a base side plate, the base bottom plate and the base side plate form a base cavity with a base opening, the handle panel includes a panel body, an inwardly recessed connecting step is provided on the lower edge of the outer periphery of the panel body, when the handle panel covers the base opening, the lower side surface of the panel body is connected to the base side plate, and the base side plate falls on the inner side of the projection range of the connecting step when viewed from bottom to top; the outer shell is L-shaped and includes a gripping section and a sleeve shaft, the gripping section includes a shell bottom plate and a shell side plate, the The sleeve shaft is connected to one end of the shell bottom plate, the shell is hollow and has a shell cavity, the edge of the shell side plate forms a first shell opening, the edge of the shell shaft sleeve forms a second shell opening, the base of the handle embedded module can be placed in the shell cavity through the first shell opening, and the upper end of the shell side plate extends into the connecting step and completely covers the joining line between the panel body and the base side plate, a bottom plate through hole is provided on the shell bottom plate, and a screw passes through the bottom plate through hole to connect the handle panel so as to connect the shell and the handle embedded module together; it also includes a clutch block rotatably arranged in the base cavity, a base through hole is provided on the base bottom plate, and the lower end of the clutch block passes through the base through hole and extends into the shell cavity defined by the sleeve shaft.

[0004] The shell is a hollow component made of thin-walled profiles, the thickness of which is between 0.2 mm and 1.0 mm. Common processing methods include stamping, welding or 3D printing. The shell made in this way is not only light in weight, but also has a variety of appearances that can be varied according to needs. In addition, the shell cavity of the L-shaped shell is also L-shaped, that is, it is composed of cavities defined by the grip section and the sleeve shaft, so that the shell cavity can not only accommodate the handle embedded module, but also cover the clutch block protruding downwards mentioned below, and the hollow square shaft can be inserted into the shell cavity through the second opening.

[0005] The handle embedded module is a component independent of the shell, and the handle embedded module and the shell can be connected to form a handle. In addition to the base and the handle panel, the handle embedded module also includes a clutch block and a joint block arranged in the base cavity, and a drive motor, a lock core and a drive rod for driving the joint block. In order to realize electrical control, it also includes a control circuit board arranged between the positioning plate and the handle panel.

[0006] The base is the main component used for supporting the lock handle. The base cavity provided on the base can provide a positioning basis for each component. In addition, when the handle embedded module is installed and combined with the shell, since the base is completely dropped into the shell, the handle panel and the shell become appearance parts, and the base is a non-appearance component. The base only needs to meet the size, structural strength and safety requirements, which makes the molding method of the base more flexible, such as common metal die-casting or plastic injection molding, without the need for special appearance treatment, and the wall thickness of the base can be made thin or a groove structure can be added to reduce its weight.

[0007] Among them, the base side panel falls within the inner side of the projection range of the connecting step, which means that when the base is connected to the handle panel, the handle panel can completely cover the base from above, and also cover the joining line between the panel body and the base side panel. When the base falls into the outer shell cavity, the upper end of the shell side panel will not be blocked by the base and can smoothly extend into the connecting step. Viewed from the side, the joining line between the panel body and the base side panel is also blocked by the shell side panel, and external liquid cannot directly enter the base cavity.

[0008] The handle panel is an appearance component that can simultaneously connect the base and the housing, and includes a panel body in the shape of a plate. Generally, in order to better position and connect with the base, a lower boss is also provided on the lower side of the panel body, and the lower boss does not exceed the projection range of the connecting step. The bottom surface of the lower boss (i.e., the lower surface of the panel body) abuts against the side plate of the base. Of course, in other equivalent embodiments, a lower positioning column can also be provided on the lower side of the panel body. Furthermore, in order to facilitate the installation of the fingerprint recognition module, a mounting hole can be provided on the panel body.

[0009] According to the above technical solution, compared with the prior art, the beneficial technical effects of the present invention are: First, the shell is made of lighter and thinner materials, which not only facilitates surface processing but also has various shapes; the base is arranged in the shell, and the base as a non-appearance component can reduce the appearance processing process, and at the same time, the parts are made into thin-walled shapes and the weight of the product is reduced by setting material reduction grooves, which not only reduces the processing difficulty and weight of the product, but also improves the surface quality of the product, the product qualification rate and the diversity of product shape changes; second, the handle embedded module is a component that can be assembled in advance, which can not only improve the assembly efficiency of the product, but also can be arranged on the base through the base and the handle panel. The electrical components and movable parts in the seat cavity form the first layer of protection; third, after the handle embedded module is connected to the outer shell, the joining line between the panel body and the base side panel falls into the outer shell cavity, which not only improves the aesthetics of the product, but also effectively reduces the entry of liquids, forms a double layer of protection for the internal components, and greatly improves the product's stability in use; fourth, the outer shell is L-shaped and includes a grip section and a sleeve shaft. In addition to protecting the handle embedded module through the grip section, the clutch block is also protected by the sleeve shaft, reducing the exposure of the movable connecting parts and improving the connection stability of the handle.

[0010] Since the double-layer lock handle has the above advantages, it can be applied to the lock. The lock includes an outer module, an inner module and a lock body, wherein the outer module is installed on the outer side of the door leaf, the inner module is installed on the inner side of the door leaf, the lock body is installed in the door leaf, the lock body is provided with a lock tongue for locking the door leaf, and the inner module includes an inner door handle; wherein the outer module includes the double-layer lock handle, and also includes a hollow square shaft, wherein the two ends of the hollow square shaft are respectively connected to the inner door handle and the double-layer lock handle, and the middle part of the hollow square shaft is connected to the lock tongue, and the lock tongue can be driven to perform telescopic activities by rotating the inner door handle or the double-layer lock handle.

When the handle panel 8 covers the base opening 73, the lower side surface of the panel body 81 is connected to the base side plate 72, and when viewed from bottom to top, the base side plate 72 falls on the inner side of the projection range of the connecting step 84; the outer shell 6 is L-shaped and includes a grip section 61 and a sleeve shaft 62, the grip section 61 includes a shell bottom plate 63 and a shell side plate 64, and the sleeve shaft 62 is connected to one end of the shell bottom plate 63 The shell 6 is hollow and has a shell cavity 60, the edge of the shell side plate 64 forms a first shell opening 65, and the edge of the shell sleeve forms a second shell opening 66, the base 7 of the handle embedded module 5 can be placed in the shell cavity 60 through the first shell opening 65, and the upper end of the shell side plate 64 extends into the connecting step 84 and completely blocks the joining line between the panel body 81 and the base side plate 72, a bottom plate through hole 67 is provided on the shell bottom plate 63, and a screw passes through the bottom plate through hole 67 to connect the handle panel 8, thereby connecting the shell 6 and the handle embedded module 5 together; it also includes a clutch block 9 rotatably arranged in the base cavity 70, and a base through hole 74 is provided on the base bottom plate 71, and the lower end of the clutch block 9 passes through the base through hole 74 and extends into the shell cavity 60 defined by the sleeve shaft 62.

[0016] The handle embedded module 5 and the shell 6 are independent components. The handle embedded module 5 can be prepared in advance as a pre-assembled component, and the two components are further connected together by screws. The base 7 is provided with a base cavity 70 to provide a positioning basis for various components, such as the control circuit board 51, clutch block 9, engagement block 52 and the drive motor 53, lock cylinder 54 and drive rod 55 for driving the engagement block 52 mentioned below. When the handle panel 8 covers the base 7, it forms the first layer of protection for the electrical parts and movable parts arranged in the base cavity 70. Since the base 7 is arranged in the shell 6, the base 7 has no appearance requirements. The base 7 only needs to meet the size, structural strength and safety requirements, which makes the molding method of the base 7 more flexible, such as common metal die casting or plastic injection molding, which can not only effectively reduce the product weight but also reduce the manufacturing cost.

[0018] The shell 6 is a hollow component made of or composed of thin-walled profiles. The thickness of the profile is generally controlled within the range of 0.2 mm to 1.0 mm. It is made by common processing methods such as stamping, welding or 3D printing. The appearance of the shell 6 can be varied according to needs, and the outer surface only needs to be simply ground or polished. It can be seen that the shell 6 is made of lighter and thinner materials, which not only reduces the processing difficulty and weight of the product, but also improves the appearance flatness of the product, the product qualification rate and the diversity of product shape changes. In addition, after the handle embedded module 5 is connected to the shell 6, the joint line between the panel body 81 and the base side panel 72 is effectively blocked by the shell 6, which not only improves the aesthetics of the product, but also forms a second layer of protection.

[0019] Among them, the shell cavity 60 of the L-shaped shell 6 is also L-shaped, so that the shell cavity 60 can not only accommodate the handle embedded module 5 to protect the base 7 of the handle embedded module 5, but also cover the clutch block 9 and the hollow square shaft 31 mentioned below, which also protects the clutch block 9.

[0020] In order to allow the base 7 to form a combination with the clutch block 9, it also includes a coupling block 52, and a slide groove 75 is also provided on the base bottom plate 71. The coupling block 52 is arranged to slide back and forth in the slide groove 75, and at least one coupling notch 91 is provided on the clutch block 9. When the coupling block 52 moves close to the clutch block 9, part of the coupling block 52 can be inserted into the coupling notch 91 so that the base 7 rotates with the clutch block 9; when the coupling block 52 moves away from the clutch block 9, the coupling block 52 is separated from the clutch block 9 so that the base 7 cannot rotate with the clutch block 9; wherein, the clutch block 9 is connected to the hollow square shaft 31, and when the coupling block 52 is in a separated state from the clutch block 9, rotating the double-layer lock handle 4 located on the outside of the door leaf will not rotate with the clutch block 9 and the hollow square shaft 31.

[0021] The driving modes of the engagement block 52 include at least the following two modes, which can be implemented separately or in combination.

[0022] The first type also includes a driving motor 53 arranged in the base cavity 70, and the driving motor 53 is connected to the coupling block 52 and can drive the coupling block 52 to move back and forth along the slide groove 75, so that the coupling block 52 can be combined with or separated from the clutch block 9.

[0023] The second type also includes a lock core 54 and a driving rod 55, one end of the driving rod 55 is connected to the lock core, and the other end extends to the side of the engaging block 52, when the lock core moves inward with the driving rod 55, the driving rod 55 can push the engaging block 52 to move and insert into the engaging notch 91 of the clutch block 9; it also includes a reset spring 56, the reset spring 56 is arranged between the engaging block 52 and the base 7, when the lock core moves outward with the driving rod 55, the reset spring 56 can push the engaging block 52 to reset and move away from the engaging notch 91.

[0024] Furthermore, in order to limit the axial movement of the clutch block 9 and the engagement block 52 , a positioning pressure plate 57 is further included.

A trigger 583 is provided on the adjusting block 58, and the adjusting block 58 can be driven to rotate by rotating the adjusting knob 22. When the trigger 583 is close to the sensing switch 59 (that is, the state when the adjusting block 58 is combined with one of the positioning holes 572 through the positioning ball 581), the sensing switch 59 can send a trigger signal to the controller, and the controller controls the driving motor 53 to drive the engaging block 52 to engage or separate with the clutch block 9 according to the different signals received.

[0027] In this embodiment, the adjustment knob 22 has three modes. The first mode is the normal door lock mode. The control circuit board 51 is also provided with a fingerprint recognition module or a password picking module. When the controller receives the correct fingerprint or password recognition signal, it controls the drive motor 53 to drive the engagement block 52 to combine with the clutch block 9 to achieve unlocking.
