Description

Technical Field

[0001] This utility model relates to locks, specifically a lock cylinder stabilization mechanism, a lock body, and a smart lock. Background Technology

[0002] Currently, some locks use electric control for unlocking. This electric control method generally requires a motor in conjunction with a reduction mechanism, which places extremely high demands on the stability of the motor installation. If the motor deviates (e.g., due to transportation vibrations or external forces), it will hinder the cooperation between the motor and the reduction mechanism. However, using a special motor mount to fix the motor will reduce installation efficiency. Therefore, how to improve the stability of motor installation while minimizing the impact on installation efficiency is a technical problem that needs to be solved. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a lock cylinder stabilization mechanism, a lock body, and a smart lock, which can improve the stability of motor installation while reducing the impact on installation efficiency, and alleviate the problem of motor misalignment caused by transportation vibration, external forces, etc., leading to obstruction of cooperation with the deceleration mechanism.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a lock cylinder stabilizing mechanism, comprising a base, an upper cover mounted on the base, and a lock cylinder mounted between the base and the upper cover. The lock cylinder has a motor, and the lock cylinder is fixedly connected to the base. A limiting member is fixedly connected to the upper cover at a position corresponding to the motor. The limiting member has elastic clamping parts on both sides of the motor. When the upper cover and the base are combined, the elastic clamping parts clamp the two sides of the motor to limit the motor.

[0005] As a further improvement of this utility model, the elastic clamping part is formed by bending the limiting member, and the bending part forms an arc transition.

[0006] As a further improvement of this utility model, the limiting member is provided with a plurality of through holes, and the upper cover is provided with rivet points at positions corresponding to the through holes, the rivet points being riveted to the through holes; and / or the end of the elastic clamping part is bent to form a flat segment, and the flat segment is used to fit the upper cover; the flat segment of the elastic clamping part is provided with through holes, and the upper cover is provided with rivet points at positions corresponding to the through holes, the rivet points being riveted to the through holes.

[0007] As a further improvement of this utility model, the base is provided with a mating part for at least part of the motor to be embedded in the position corresponding to the motor.

[0008] As a further improvement of this utility model, the mating part is a groove or a window.

[0009] As a further improvement of this utility model, the mating part is a window, and the motor is provided with a code mark at the position corresponding to the window, and the code mark is exposed through the window.

[0010] As a further improvement of this utility model, the position of the motor corresponding to the mating part protrudes from the plane where the lock cylinder and the base are in contact.

[0013] The beneficial effects of this utility model are as follows: by fixing the lock cylinder to the base, a limiting component with an elastic clamping part is set on the upper cover at the position corresponding to the motor. When the upper cover and the base are combined, the elastic clamping part can clamp the two sides of the motor to limit the motor. There is no need to set up a special motor base.

[0020] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0021] Referring to Figures 1-5, this embodiment provides a lock cylinder stabilizing mechanism, including a base 1, an upper cover 2 mounted on the base 1, and a lock cylinder 3 mounted between the base 1 and the upper cover 2. The lock cylinder 3 has a motor 4. The lock cylinder 3 is fixedly connected to the base 1. A limiting member 5 is fixedly connected to the upper cover 2 at a position corresponding to the motor 4. The limiting member 5 is provided with elastic clamping parts 6 on both sides of the motor 4. When the upper cover 2 and the base 1 are combined, the elastic clamping parts 6 clamp the two sides of the motor 4 to limit the movement of the motor 4.

[0022] The lock cylinder 3 can be detachably or non-detachably fixed to the base 1 through conventional fixing methods such as screw connection and snap-fit ​​connection. The limiting component 5 can be fixedly connected to the upper cover 2 corresponding to the position of the motor 4 through welding, riveting, etc. In the actual assembly process, the lock cylinder 3 is first placed in the preset installation area of ​​the base 1 and fixed. Then, the upper cover 2 is closed on the base 1 along the preset direction. The upper cover 2 drives the limiting component 5 to move synchronously until the upper cover 2 and the base 1 are fully combined. At this time, the elastic clamping parts 6 on both sides of the limiting component 5 just contact the two side surfaces of the motor 4 and form a clamping state, generating force on the motor 4. Lateral limiting force; this structure eliminates the need for additional dedicated motor 4 mounting steps. The motor 4 can be simultaneously limited during the standard assembly process of base 1, top cover 2, and lock cylinder 3, effectively reducing the impact on installation efficiency. At the same time, the elastic clamping part 6 is made of elastic material, which can adapt to the slight dimensional deviation of the motor 4 housing. When the lock is subjected to transportation vibration or external impact, the elastic clamping part 6 can buffer the impact force through its own elastic deformation, alleviate the situation of motor 4 deviating, and thus improve the problem of obstruction between motor 4 and reduction mechanism, and improve the stability of motor 4 installation.

[0023] In order to facilitate the processing and forming of the elastic clamping part 6 and avoid scratching damage to the housing of the motor 4, in an optional embodiment, the elastic clamping part 6 is formed by bending the limiting member 5, and the bending point forms an arc transition.

[0024] The limiting component 5 can be made of metal sheet (such as spring steel, galvanized steel sheet, etc.) or engineering plastic sheet with a certain degree of elasticity. Through mature processes such as stamping and bending, a specific area of ​​the limiting component 5 is bent to form an elastic clamping part 6 that fits both sides of the motor 4. During the bending process, by adjusting the parameters of the bending die, a smooth arc transition is formed at the bend. When the elastic clamping part 6 contacts both sides of the motor 4 and applies clamping force, the arc transition of the bend can avoid direct contact between the sharp edge and the motor 4 housing, reducing scratches and wear on the motor 4 housing and protecting the integrity of the motor 4 housing. At the same time, the bending forming process is simple, low-cost, and easy to mass-produce. It can also ensure that the elastic clamping part 6 has stable elastic recovery performance, ensuring the clamping and limiting effect on the motor 4 during long-term use, and further improving the stability and service life of the motor 4 after installation.

[0025] To enhance the connection between the limiting member 5 and the upper cover 2 and prevent relative displacement between the limiting member 5 and the upper cover 2 during long-term use, further optimization can be achieved by the following methods: the limiting member 5 is provided with several through holes, and the upper cover 2 is provided with rivet points 7 at the corresponding positions of the through holes, and the rivet points 7 are riveted to the through holes; and / or the end of the elastic clamping part 6 is bent to form a flat section 61, and the flat section 61 is used to fit the upper cover 2; the flat section 61 of the elastic clamping part 6 is provided with through holes, and the upper cover 2 is provided with rivet points 7 at the corresponding positions of the through holes, and the rivet points 7 are riveted to the through holes.

[0026] When using the connection method with through holes in the body of the limiting component 5, several through holes are first processed at the preset fixing position of the limiting component 5 through drilling, punching, and other processes (the number of through holes can be set to 4-6 according to the size of the limiting component 5 and the fixing requirements). During the injection molding or stamping process, the upper cover 2 simultaneously forms raised rivet points 7 at the positions corresponding to the through holes of the limiting component 5. During assembly, the through holes of the limiting component 5 are precisely aligned with the rivet points 7 of the upper cover 2. Through hot riveting (heating the rivet points 7 to soften and deform them) or cold riveting (deforming the rivet points 7 through mechanical pressure), the rivet points 7 fill the through holes and form a barb structure, thereby achieving a tight fixation between the limiting component 5 and the upper cover 2. When using elastic clamping... When the connection method of the end of part 6 is provided with a flat section 61, the end of the elastic clamping part 6 is first bent to form a flat section 61 that fits against the surface of the upper cover 2 (the area of ​​the flat section 61 can be set according to the connection strength requirements). A through hole is machined on the flat section 61, and a riveting point 7 is provided at the corresponding position of the upper cover 2. Then, it is fixed by the above riveting process. Both connection methods can greatly improve the connection strength between the limiting part 5 and the upper cover 2, and prevent the limiting part 5 from being displaced relative to the upper cover 2 due to vibration, external force, etc. during the use of the lock. This ensures that the elastic clamping part 6 can continuously and stably clamp and limit the motor 4. At the same time, the riveting process is simple to operate and will not significantly increase the installation steps, ensuring that the overall installation efficiency is not affected too much.

[0027] In some options, in order to limit the motor 4 from multiple directions and further improve the stability of the motor 4 installation, and at the same time assist the initial positioning of the lock cylinder 3 on the base 1, the base 1 is provided with a mating part 11 for at least part of the motor 4 to be embedded in the position corresponding to the motor 4.

[0028] During the processing of the base 1, a mating part 11 is machined on the side of the base 1 facing the lock cylinder 3, according to the external dimensions and installation requirements of the motor 4. When the lock cylinder 3 is fixedly connected to the base 1, part of the structure of the motor 4 (such as the end of the motor 4, the middle shell, etc.) is embedded into the mating part 11. The inner wall of the mating part 11 can form a longitudinal or circumferential limiting effect on the motor 4. The mating part 11 and the elastic clamping part 6 of the upper cover 2 limiting part 5 form a synergistic limiting effect, constraining the motor 4 from different directions, reducing the possibility of displacement of the motor 4 in multiple dimensions, and further alleviating the problem of motor 4 offset. At the same time, the structure of the motor 4 partially embedded in the mating part 11 can also play a positioning and guiding role during the installation of the lock cylinder 3, helping the lock cylinder 3 to quickly find the accurate installation position on the base 1, ensuring the relative position of the lock cylinder 3 and the base 1 is accurate, indirectly improving the matching accuracy of the motor 4 and the reduction mechanism, and improving the overall operation stability of the lock.

[0029] In order to accommodate the structural space of different locks and the installation requirements of motor 4, the mating part 11 is a groove or a window based on the above-mentioned mating part 11.

[0030] When the mating part 11 is designed as a groove, the groove is located on the side of the base 1 facing the lock cylinder 3. The depth of the groove can be set to 1 / 5 to 1 / 4 of the diameter of the motor 4 (adjusted according to the size of the motor 4 and the limiting requirements). The inner diameter of the groove matches the outer diameter of the embedded part of the motor 4. After the motor 4 is embedded in the groove, the inner wall of the groove can form a circumferential limiting on the motor 4. Moreover, the groove structure is only recessed in a local area of ​​the base 1, which has little impact on the overall structural strength of the base 1. It is suitable for scenarios where the internal space of the base 1 is sufficient. When the mating part 11 is designed as a window, the window extends through the thickness direction of the base 1. Part of the structure of the motor 4 can extend out of the outside of the base 1 through the window. It is suitable for scenarios where the size of the motor 4 is large or the internal space of the base 1 is limited. At this time, the edge of the window can still effectively limit the outer periphery of the motor 4. The two forms of mating part 11 can be flexibly selected according to the actual lock structure design, the size of the motor 4 and other requirements. Both can realize the function of partially embedding the motor 4 and assisting in limiting. While improving the installation stability of the motor 4, it also enhances the applicability of the stabilizing mechanism of the lock cylinder 3.

[0031] To facilitate the quick acquisition of motor 4 information by staff during installation and maintenance, and to verify motor 4 parameters without disassembling the lock, when the mating part 11 is a window, a coded mark is set at the position of the window corresponding to the motor 4, and the coded mark is exposed through the window.

[0032] During the production of motor 4, key information such as the lock model, production batch, and anti-counterfeiting information is coded and marked using laser marking and wear-resistant labels. These coded labels are then placed on the outer surface of the window of the corresponding base 1 of motor 4. When motor 4 is partially embedded in the window, the coded labels are directly exposed through the window, allowing workers to visually observe them without disassembling the base 1, top cover 2, or lock cylinder 3. This design facilitates verification of lock compatibility and anti-counterfeiting during installation, preventing incorrect installations. It also facilitates quick confirmation of motor 4 parameters during later maintenance, improving repair efficiency. Furthermore, the coded labels do not affect the limiting function of the mating part 11 on motor 4, enhancing the ease of installation and maintenance, as well as the anti-counterfeiting features of the lock while ensuring the stability of motor 4 installation.

[0033] In order to enable the mating part 11 to make fuller contact with the motor 4, enhance the limiting effect on the motor 4, and reduce the wobbling space of the motor 4 in the mating part 11, in some embodiments, the position of the motor 4 corresponding to the mating part 11 protrudes from the plane where the lock cylinder 3 and the base 1 are in contact.

[0034] When designing the lock cylinder 3, a specific part of the motor 4 (such as the end of the motor 4 near the base 1) is designed to protrude from the mating surface of the lock cylinder 3 and the base 1 (the mating surface is the plane in contact between the lock cylinder 3 and the base 1). The protrusion height can be set according to the depth of the mating part 11, generally 2-5mm. When the lock cylinder 3 and the base 1 are fixedly connected, the protruding part of the motor 4 can be more deeply embedded into the mating part 11 of the base 1, making the contact area between the mating part 11 and the motor 4 larger and the limiting constraint more sufficient. This further alleviates the problem of motor 4 offset. At the same time, this protruding structure only requires a slight adjustment to the installation position of the motor 4 on the lock cylinder 3, without making significant changes to the main structure of the lock cylinder 3. It is easy to implement and can improve the stability of the motor 4 installation without increasing too much cost.

[0035] In order to achieve precise matching between the motor 4 and the mating part 11, further improve the positioning accuracy of the lock cylinder 3 on the base 1, and ensure the matching accuracy between the motor 4 and the reduction mechanism, the position of the motor 4 corresponding to the mating part 11 is adapted to the shape and size of the mating part 11, so as to position the lock cylinder 3 when the motor 4 and the mating part 11 are mated.

[0036] During the design phase, based on the external contour (such as circle, square, polygon, etc.) of the part corresponding to the motor 4 in mating part 11, the shape of mating part 11 is designed to be a structure that is completely adapted to it. This completely adapted structure does not exclude gaps caused by tolerances. When the lock cylinder 3 is assembled with the base 1, the part of the motor 4 corresponding to mating part 11 can be precisely embedded in mating part 11. Since the shape and size of the two are adapted, the motor 4 cannot be laterally offset within mating part 11. Thus, through the fixed connection between the motor 4 and the lock cylinder 3, the position of the lock cylinder 3 on the base 1 is fixed, achieving precise positioning of the lock cylinder 3. This precise adaptation structure not only further enhances the limiting effect of mating part 11 on the motor 4, but also assists the lock cylinder 3 in being quickly and accurately installed on the base 1, ensuring the accurate relative position of the lock cylinder 3 with the base 1, the top cover 2, and the reduction mechanism, reducing the problem of poor matching between the motor 4 and the reduction mechanism caused by the offset of the lock cylinder 3, and further improving the overall operational stability and reliability of the lock.

[0037] The above solution can be applied to locks or smart locks. When applied to smart locks, the base 1 is the sealing plate and the top cover 2 is the panel.

[0038] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
