Description
Technical Field
[0001] This utility model relates to the field of smart door lock technology, specifically a smart door lock with shockproof function. Background Technology
[0002] With the rapid development of the smart home industry, smart door locks, due to their convenient unlocking (fingerprint, password, NFC, etc.), remote control, and security alarm functions, are gradually replacing traditional mechanical door locks and becoming the mainstream choice for homes, offices, and commercial spaces. The collision between the door and the door frame when opening and closing the door, the transmitted vibration caused by moving heavy objects in the corridor, and even minor earthquakes in some areas can all impact the precision components inside the smart door lock (such as the fingerprint recognition module, main control chip, and mechanical transmission structure). Existing smart door locks use a sealing ring between the door and the door panel during installation, which gives the smart door lock a shock absorption function. In daily use, the sealing ring is affected by environmental factors (high and low temperature cycles, erosion by moisture) and mechanical friction (reciprocating motion of the lock tongue, vibration friction from opening and closing the door), and will gradually show signs of wear such as elasticity decay, surface cracking, or even breakage. When the sealing ring is worn, its support for the internal components of the door lock is greatly reduced, the balance that was originally maintained by the sealing ring is broken, and the gap between the door lock body and the door panel increases due to insufficient filling by the sealing ring. The vibration generated by opening and closing the door and the impact from external force will be transmitted to the door lock body through the door panel. At this time, the structure of the traditional door lock, which is fixed by a single bolt, is difficult to resist the risk of displacement, which in turn causes the door lock to loosen.
[0003] Therefore, a smart door lock with shockproof function is proposed to address the above problems. Utility Model Content
[0004] The purpose of this invention is to provide an intelligent door lock with shockproof function to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A smart door lock with shockproof function includes a door lock body, the door lock body has an internal mounting groove with a sealing ring installed inside the mounting groove, and the door lock body has stabilizing mechanisms on the upper and lower sides. The stabilizing mechanism includes a stabilizing clamp, a locking block fixedly connected to the outer side of the door lock body, a sliding plate fixedly connected to the outer side of the locking block, a ball bearing inside the sliding plate, a locking groove inside the stabilizing clamp, a moving groove in the side wall of the locking groove, a connecting post fixedly connected to the inner wall of the locking groove, a rubber plate fixedly connected to the outer side of the connecting post, an anti-slip hole inside the locking block, and a limit groove at the bottom of the anti-slip hole.
[0006] As a further optimization of this utility model, the following features are provided: a fingerprint keypad is installed inside the door lock body, and a mounting hole is provided inside the stabilizing clamp, with a bolt threaded into the mounting hole.
[0007] As a further optimization of this utility model, the stabilizing clips are symmetrically distributed on the upper and lower sides of the door lock body, and the inner walls of the stabilizing clips are adapted to the upper and lower sides of the door lock body.
[0008] As a further optimization of this utility model, the snap-fit block is adapted to the snap-fit groove, the sliding plate is symmetrically distributed on the outside of the snap-fit block, and the sliding plate is adapted to the moving groove.
[0009] As a further optimization of this utility model, the ball bearing is uniformly and rotatably engaged inside the slide plate, and the end of the ball bearing away from the slide plate is rotatably connected to the inner wall of the moving groove.
[0010] As a further optimization of this utility model, the connecting column is adapted to the anti-slip hole, the number of rubber plates is the same as the limiting groove, and the rubber plates are located inside the limiting groove.
[0011] As a further optimization of this utility model, the mounting holes and bolts are symmetrically distributed inside the stabilizing clamp, and one end of the bolt is installed inside the door panel.
[0012] Compared with the prior art, the beneficial effects of this utility model are: In this utility model, the stabilizing clamp is tightly fixed to the door panel by bolts, the snap-fit block and the snap-fit groove are precisely matched, the connecting column is embedded in the anti-slip hole and the rubber plate is in the limiting groove to assist in the limiting position. The combination of multiple structures can firmly fix the door lock body, effectively offsetting the impact of the wear of the sealing ring on the door lock fixing effect, and preventing the door lock from loosening or shifting due to the weakening of the sealing protection of the sealing ring.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0017] Please see Figures 1-6 This utility model provides a technical solution: A smart door lock with shockproof function includes a door lock body 1, an installation groove 3 is provided inside the door lock body 1, a sealing ring 4 is installed inside the installation groove 3, and a stabilizing mechanism 5 is provided on the upper and lower sides of the door lock body 1. The stabilizing mechanism 5 includes a stabilizing clamp 51, a locking block 54 fixedly connected to the outside of the door lock body 1, a sliding plate 55 fixedly connected to the outside of the locking block 54, a ball bearing 56 disposed inside the sliding plate 55, a locking groove 57 opened inside the stabilizing clamp 51, a moving groove 58 opened in the side wall of the locking groove 57, a connecting post 59 fixedly connected to the inner wall of the locking groove 57, a rubber plate 510 fixedly connected to the outside of the connecting post 59, an anti-slip hole 511 opened inside the locking block 54, and a limiting groove 512 opened at the bottom of the inner side of the anti-slip hole 511.
[0018] It should be noted that: the stabilizing clips 51 are symmetrically distributed on the upper and lower sides of the door lock body 1, and the inner wall of the stabilizing clips 51 is adapted to the upper and lower sides of the door lock body 1; the locking block 54 is adapted to the locking groove 57; the sliding plate 55 is symmetrically distributed on the outer side of the locking block 54, and the sliding plate 55 is adapted to the moving groove 58; the ball bearings 56 are evenly and rotatably locked inside the sliding plate 55, and the end of the ball bearings 56 away from the sliding plate 55 is rotatably connected to the inner wall of the moving groove 58; the connecting post 59 is adapted to the anti-slip hole 511; the number of rubber plates 510 is the same as that of the limiting groove 512, and the rubber plates 510 are located inside the limiting groove 512.
[0019] Furthermore, the symmetrically distributed mounting holes 52 and bolts 53 inside the stabilizing clip 51 always firmly fix the stabilizing clip 51 to the door panel. One end of the bolt 53 is screwed into the door panel to form a rigid fixing structure. Even if the internal support of the door lock body 1 is weakened due to the wear of the sealing ring 4, the stabilizing clip 51 can still provide stable external support for the door lock body 1 through the snap-fit cooperation with the door lock body 1 and the rigid connection between the bolt 53 and the door panel. This prevents the door lock body 1 from becoming loose or shifting due to insufficient internal support, and ensures that the connection strength between the door lock body 1 and the door panel is not affected by the wear of the sealing ring 4.
[0020] Specifically: The mounting groove 3 inside the door lock body 1 is not a simple groove structure. Its groove wall is precision polished to ensure a good fit with the sealing ring 4. Under normal conditions, the sealing ring 4 can completely fill the gap between the mounting groove 3 and the internal components. It can not only block impurities, but also exert a slight squeeze on the internal components through its own elasticity, so that the components can maintain a relatively fixed position inside the door lock body 1, indirectly reducing the impact of component shaking on the overall stability of the door lock body 1.
[0021] As a further implementation of this solution, a fingerprint keypad 2 is installed inside the door lock body 1, and a mounting hole 52 is opened inside the stabilizing clip 51, with a bolt 53 threaded inside the mounting hole 52.
[0022] It should be noted that the mounting holes 52 and bolts 53 are symmetrically distributed inside the stabilizing clamp 51, and one end of the bolts 53 is installed inside the door panel.
[0023] Furthermore, the diameter of the connecting post 59 and the diameter of the anti-slip hole 511 are controlled within a very small range to ensure that the connecting post 59 will not wobble significantly after being inserted. The rubber plate 510 on the outside of the connecting post 59 is made of highly elastic nitrile rubber, and its thickness is slightly greater than the depth of the limiting groove 512. When the rubber plate 510 is inserted into the limiting groove 512, it will undergo slight deformation due to compression. This deformation can not only fill the tiny gap between the connecting post 59 and the anti-slip hole 511, but also form continuous elastic pressure to firmly "fix" the connecting post 59 in the anti-slip hole 511, preventing the connecting post 59 from separating from the anti-slip hole 511 or creating gaps due to vibration. This further strengthens the connection stability between the door lock body 1 and the stabilizing clip 51 and offsets the problem of increased vibration transmission after the sealing ring 4 is worn.
[0024] Work process: After long-term use, the sealing ring 4 in the mounting groove 3 inside the door lock body 1 is prone to wear due to friction and aging. Its original function of filling gaps and helping to maintain the stability of the internal structure of the door lock will be weakened. If only the sealing ring 4 is relied upon, the fit between the internal components of the door lock and the shell may decrease. Long-term exposure to door opening and closing vibrations and external force touches may easily cause the connection between the door lock body 1 and the door panel to loosen or even shift. However, the stabilizing mechanisms 5 on the top and bottom sides of the door lock can offset this problem through the cooperation of multiple structures: the snap-fit block 54 on the outside of the door lock body 1 is closely matched with the snap-fit groove 57 inside the stabilizing clamp 51, the sliding plate 55 is embedded in the moving groove 58 to limit horizontal displacement, the connecting post 59 on the inner wall of the snap-fit groove 57 is embedded in the anti-slip hole 511, the rubber plate 510 is snapped into the limiting groove 512 to absorb vibration and fill gaps, and at the same time, the stabilizing clamp 51 is rigidly fixed to the door panel by the bolt 53 in the mounting hole 52. Even if the sealing ring 4 is worn and the internal support is weakened, it can still provide stable external support for the door lock body 1. During daily opening and closing of the door and unlocking, the rubber plate 510 can absorb the slight vibration generated by the mechanical transmission, and the ball bearing 56 can also offset some of the vibration displacement. Together with the bolt 53 for fixing and locking limit, a triple protection is formed, which completely offsets the adverse effect of the wear of the sealing ring 4 on the fixing of the door lock body 1, ensuring that the door lock body 1 is always tightly connected to the door panel and maintains normal function.
[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
