Description

Technical Field

[0001] The utility model belongs to the technical field of locks, and particularly relates to a driving mechanism of a fingerprint lock and a screen window. Background Art

[0002] A screen window is a mesh structure installed on a window. Its main purpose is to prevent small insects such as mosquitoes and flies from entering the room, while maintaining ventilation and lighting in the room. Moreover, the safety of the screen window also needs to be ensured. In particular, it should be avoided that the screen window is accidentally opened, causing people or pets to fall from the building, and it also has an anti-theft function.

[0003] As a modern security protection device, the technological evolution of fingerprint locks is inseparable from the continuous improvement of social needs. With the increasing limitations of traditional mechanical locks in terms of convenience, security, and management difficulty, people have begun to seek more efficient and secure lock solutions. In this context, fingerprint locks have emerged and quickly become the focus of market attention with their unique fingerprint recognition technology.

[0004] The core of a fingerprint lock lies in its driving technology, which is directly related to the opening speed, stability, and security of the lock. Currently, in addition to ensuring the driving force magnitude, fingerprint locks also have relatively high requirements for the installation space. Summary of the Utility Model

[0005] In order to solve the above technical problems, the utility model discloses a driving mechanism of a fingerprint lock, which can realize installation in a smaller space on the basis of meeting the driving force magnitude. The utility model also discloses a fingerprint lock with the above driving mechanism.

[0006] The specific technical solution of the utility model is as follows:

[0007] A driving mechanism of a fingerprint lock, which is built in the lock box of the fingerprint lock, includes:

[0008] A positioning member;

[0009] A movable member one and a movable member two that can move relative to each other, the movable member one is slidably connected to the positioning member, and the movable member two is slidably connected to the movable member one; and

[0010] A power source for driving the synchronous relative movement of the movable member one and the movable member two.

[0011] The positioning member is a component fixedly installed in the lock box. When the power source is activated, since the first moving member and the second moving member move relatively synchronously, in this process, if the movement of the first moving member and the second moving member is guided, the unlocking effect can be improved well, and the use stability of the fingerprint lock can be effectively improved. At this time, by using existing components, the first moving member is slidably connected to the positioning member, and the second moving member is slidably connected to the first moving member. That is, the movement of the first moving member is guided by the positioning member, and the movement of the second moving member is guided by the first moving member. At this time, it is possible to avoid an increase in the volume of the lock box due to the addition of extra components. In other words, within the rated volume, the assembly requirements of the drive mechanism can be met. In other words, the drive mechanism can be installed in a smaller space.

[0012] Preferably, an intermediate member is provided between the first moving member and the second moving member, and the power source drives the intermediate member to act so that the first moving member and the second moving member move relatively synchronously.

[0013] The first moving member and the second moving member are respectively connected to the intermediate member. Therefore, when the intermediate member acts, both the first moving member and the second moving member move under the action of the intermediate member. Compared with the technical solution in which the intermediate member only drives one of them and the other follows, it can effectively improve the driving efficiency and avoid driving delay.

[0014] Preferably, the intermediate member is configured as a toothed moving member;

[0015] The first moving member and the second moving member are respectively meshed with the toothed moving member, and the toothed moving member rotates around its own axis to drive the first moving member and the second moving member to move relatively synchronously.

[0016] This structure is simple, easy to assemble, and has good stability.

[0017] Preferably, waist-shaped holes are respectively formed in the middle parts of the first moving member and the second moving member, a first rack and a second rack are respectively arranged on the opposite sides of the two waist-shaped holes, and the toothed moving member is meshed with the first rack and the second rack.

[0018] The waist-shaped holes formed in the first moving member and the second moving member are large enough for the toothed moving member to pass through so that it can be meshed with the first rack and the second rack at the same time. It can be known that for any one of the waist-shaped holes, when the toothed moving member is meshed with the corresponding rack, there is a gap between the inner side wall of the waist-shaped hole where the rack is not provided and the toothed moving member to avoid movement interference.

[0019] Preferably, the first moving member and the second moving member are in a stacked structure.

[0020] The stacked first moving member and second moving member can further reduce the installation volume, so that the drive mechanism can be reliably assembled in the thickness direction of the window screen.

[0021] Preferably, the positioning member is provided with a concave placing portion, and the first moving member is limited in movement in the movement direction by the two opposite inner walls of the placing portion.

[0022] Since the placement part is concave, the installation volume of the driving mechanism can be further reduced. At this time, the inner wall of the placement part can be used to effectively limit the movement of the first moving part in its moving direction, thereby ensuring the unlocking efficiency and guaranteeing the unlocking reliability.

[0023] Preferably, stop parts are provided at the ends of the first moving part and the second moving part that are away from each other to prevent the first moving part and the second moving part from moving excessively. The stop part of the second moving part is located inside the placement part and is limited in movement in the moving direction by the two opposite inner walls of the placement part.

[0024] The stop part can limit the movement length of the first moving part / second moving part. Thus, on the basis of ensuring that the fingerprint lock has good locking performance, it can prevent the power source from being damaged due to excessive driving, and at the same time, it can also prevent the first moving part / second moving part from damaging the internal structure of the lock box.

[0025] Preferably, the first moving part and the second moving part are both provided with driving parts for driving the relatively movable first lock tongue and the second lock tongue to move synchronously.

[0026] The action of the power source causes the first moving part and the second moving part to move relatively synchronously. Therefore, the driving parts of the two also move relatively at the same time. At this time, the two driving parts can cooperate with the first lock tongue and the second lock tongue respectively, and the first lock tongue and the second lock tongue also move relatively synchronously, thereby realizing the unlocking of the fingerprint lock.

[0027] Preferably, the positioning part is provided with a movement hole, and the driving parts of the first moving part and the second moving part extend out from the movement hole.

[0028] The setting of the movement hole can further reduce the installation volume of the driving mechanism, prevent the driving part from extending from the side of the first moving part / second moving part to the position of the corresponding lock tongue, and thus further reduce the installation space in the width direction of the screen window.

[0029] A screen window, including a fingerprint lock, and the fingerprint lock includes the driving mechanism as described above.

[0030] Compared with the prior art, the structure of the present utility model is simple and compact. On the basis that the power source can apply sufficient driving force, it can effectively reduce the installation space of the driving mechanism and well realize the miniaturization of the structure and the miniaturization of the assembly.

Detailed implementation manners

[0042] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below in conjunction with the specific implementation manners.

[0043] As Figures 1 to 7 shown, a driving mechanism of a fingerprint lock is built in the lock box of the fingerprint lock, and includes a positioning member 1, a first moving member 2 and a second moving member 3 that can move relative to each other, and a power source 4; the first moving member 2 is slidably connected to the positioning member 1, and the second moving member 3 is slidably connected to the first moving member 2; the power source 4 is used to drive the first moving member 2 and the second moving member 3 to move synchronously relative to each other.

[0044] The driving mechanism is built into the lock box; the lock box is generally assembled inside the screen window, and the screen window has a relatively narrow thickness. Therefore, the mechanical structure of the fingerprint lock needs to be assembled in a relatively small installation space. Although most fingerprint locks can achieve this currently, in order to ensure that the movement guides of the first moving part 2 and the second moving part 3 meet the requirements, additional guiding parts are required. This results in an additional installation volume on top of the original installation volume, which may cause the screen window to be unable to be equipped with a fingerprint lock. In other words, the manufacturer needs to produce and manufacture different products for different specifications of screen windows, thus increasing the accessory cost, as well as the design cost and manufacturing cost.

[0045] In order to improve the driving efficiency of the power source 4, an intermediate part is arranged between the first moving part 2 and the second moving part 3. The power source 4 drives the intermediate part to move, so that the first moving part 2 and the second moving part 3 move relatively synchronously. The driving force of the power source 4 acts on the intermediate part, enabling the intermediate part to directly drive the first moving part 2 and the second moving part 3, which has a relatively high driving efficiency and reduces power loss. The intermediate part can be a gear mechanism 5, a link mechanism 6, a screw mechanism 7, etc. As Figure 8 shown, when the intermediate part is a gear mechanism 5, both sides of the gear mechanism 5 are respectively engaged with the first moving part 2 and the second moving part 3. Since the first moving part 2 and the second moving part 3 need to maintain a sliding fit and the driving of the intermediate part also needs to be ensured, the installation volume is relatively large. Similarly for the link mechanism 6 and the screw mechanism 7. As Figure 9 shown in the figure for the link mechanism 6, both ends of the link mechanism 6 are elastically hinged to the first moving part 2 and the second moving part 3 respectively. As Figure 10 shown in the figure for the screw mechanism 7, both ends of the screw mechanism 7 are respectively engaged with the first moving part 2 and the second moving part 3. In this embodiment, in order to further reduce the installation space, the first moving part 2 and the second moving part 3 are in a stacked structure. In this embodiment, the intermediate part is configured as a gear-driven part 8; the first moving part 2 and the second moving part 3 are respectively engaged with the gear-driven part 8, and the gear-driven part 8 rotates around its own axis to drive the first moving part 2 and the second moving part 3 to move relatively synchronously. Further, waist-shaped holes are respectively opened in the middle parts of the first moving part 2 and the second moving part 3, and a first rack 10 and a second rack 11 are respectively arranged on the opposite sides of the two waist-shaped holes 9. The gear-driven part 8 is engaged with the first rack 10 and the second rack 11. In this embodiment, the first moving part 2 and the second moving part 3 are stacked in the width direction of the screen window and achieve a sliding fit, and most of the waist-shaped holes 9 opened in the two also overlap on the projection plane in the width direction of the screen window. As Figure 3 、 Figure 7As shown, a first rack 10 is provided inside the right side of the waist-shaped hole 9 of the first moving part 2. Correspondingly, a first rack 10 is provided on the left side of the waist-shaped hole 9 of the second moving part 3. When the gear moving part 8 is engaged, there is a gap between the gear moving part 8 and the left side wall of the waist-shaped hole 9 of the first moving part 2, and at the same time, there is a gap between the gear moving part 8 and the right side wall of the waist-shaped hole 9 of the second moving part 3. It should be noted that in this embodiment, the power source 4 is a motor, and its installation position is in the width direction of the screen window. That is to say, in the projection in the width direction of the screen window, the power source 4, the first moving part 2, and the second moving part 3 overlap, so that the driving mechanism can be inserted and installed from the narrow side of the screen window. Thus, when the power source 4 is started, the gear moving part 8 rotates. Since the positioning part 1 remains stationary, the first moving part 2 and the second moving part 3 can move relative to each other as the gear moving part 8 rotates. The relative movement mentioned above refers to the mutual separation movement and the mutual approaching movement between the first moving part 2 and the second moving part 3. It should also be noted that in the lock box, a skeleton 12 is provided. The skeleton 12 has a certain hardness and can fill the voids in the lock box. At this time, one side wall of the filling part is located on the side of the second moving part 3 away from the first moving part 2, and the two slide into contact with each other or have a very small gap. Therefore, in the width direction of the screen window, the assembly of the first moving part 2 and the second moving part 3 can be limited to prevent the path from deviating during the relative movement and reducing the driving efficiency. In addition, the skeleton 12 can be used to support or connect and fix the power source 4, the power supply, the circuit board, etc.

[0046] In this embodiment, the positioning part 1 is provided with a concave placing part 13, and the first moving part 2 is limited in the moving direction by the two opposite inner walls of the placing part 13. The placing part 13 can provide a space for positioning and assembling the first moving part 2, and at the same time enable the first moving part 2 and the positioning part 1 to achieve a quick sliding fit.

[0047] In this embodiment, stop parts 14 are provided at the ends of the first moving part 2 and the second moving part 3 that are away from each other, for preventing the first moving part 2 and the second moving part 3 from moving excessively. The stop part of the second moving part 3 is located inside the placing part 13 and is limited in the moving direction by the two opposite inner walls of the placing part 13. The radial cross-section of the placing part 13 is rectangular, and the two opposite inner walls mentioned above refer to the two opposite long sides. Thus, through the setting of the placing part 13, on the basis of positioning and installing the first moving part 2, the second moving part 3 and the first moving part 2 can be more quickly positioned and assembled. Specifically, such as Figure 3As shown, the first moving part 2 is assembled into the placement part 13. At this time, the upper end of the first moving part 2 is located at the upper end of the placement part 13. Then, the second moving part 3 is placed on the first moving part 2, so that the lower end of the second moving part 3 is located at the lower end of the placement part 13. At this time, the first moving part 2 and the second moving part 3 are farthest apart from each other at the extreme positions. Therefore, after the toothed moving part 8 is assembled, it is equivalent to the driving mechanism being in the locked state at this time. After corresponding position adjustment and adaptation, the overall assembly of the first moving part 2, the second moving part 3, the toothed moving part 8, and the power source 4 can be quickly achieved.

[0048] In this embodiment, both the first moving part 2 and the second moving part 3 are provided with driving parts 15 for driving the first locking tongue and the second locking tongue that can move relatively to move synchronously. The first locking tongue and the second locking tongue are necessary parts for closing the screen window, and their driving is realized through the movement of the driving part 15. A reset part is arranged between the first locking tongue and the second locking tongue. After unlocking, the reset part stores energy. The driving part 15 is reset by the power source 4, and the reset part releases the stored energy to reset the first locking tongue and the second locking tongue, thereby achieving locking.

[0049] In this embodiment, the positioning part 1 is provided with a movement hole 16, and the driving parts 15 of the first moving part 2 and the second moving part 3 extend out from the movement hole 16. Specifically, as Figure 7 shown, the positioning part 1 has a first blocking part 17, a second blocking part 18, and a third blocking part 19; the first blocking part 17 and the second blocking part 18 are respectively located at both ends of the positioning part 1, and the third blocking part 19 is located in the middle of the positioning part 1. There is a movement space between the first blocking part 17 and the third blocking part 19, and there is also a movement space between the second blocking part 18 and the third blocking part 19. The above-mentioned movement space is the movement hole 16. The driving parts 15 of the first moving part 2 and the second moving part 3 are guided by movement in the movement hole 16. Therefore, it can also better meet the driving requirements for the first locking tongue and the second locking tongue. It can be known that since the driving part 15 passes through the positioning part 1, the installation volume is correspondingly reduced, that is, it is avoided that the driving part 15 crosses over from the outside of the positioning part 1 to achieve the corresponding matching with the locking tongue.

[0050] Thus, on the basis of the above embodiments, this embodiment also discloses a screen window, and the screen window includes a fingerprint lock. The fingerprint lock includes the above-mentioned driving mechanism. When the fingerprint lock is actually applied, it can well solve the problem of too large installation volume caused by ensuring the driving force of the power source 4 in the prior art, so as to adapt to more different models of screen windows on the premise of ensuring safety.

[0051] The above are only the preferred embodiments of the present utility model. It should be noted that the above preferred embodiments should not be construed as limiting the present utility model, and the protection scope of the present utility model should be subject to the scope defined by the claims. For those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as within the protection scope of the present utility model.
