Description

Technical Field

[0001] This utility model relates to the field of smart lock technology, and in particular to a foldable motor lock core reducer structure. Background Technology

[0002] With the development of science and technology and people's increasing emphasis on home security, smart locks have widely replaced traditional mechanical locks and become the mainstream lock choice due to their intelligent advantages in user identification, security, and management. The motor lock cylinder, as the core driving component for automatic unlocking in smart locks, typically consists of a motor, gearbox, fixing part, and lock cylinder sleeve. The power output from the motor is reduced in speed by the gearbox and then drives the lock cylinder core to rotate through a stable transmission structure, completing the lock's opening and closing operation.

[0003] To adapt to the design trend of miniaturization and thinning of smart locks, existing technologies have achieved many breakthroughs. For example, Chinese utility model patent number 202620005456.5 describes a motor lock cylinder, including a motor, a gearbox connected to the motor, and a lock cylinder rotor. Its characteristic is that it also includes a U-shaped main body and a lock cylinder sleeve for installing a key lock cylinder, installed on the side of the main body away from the gearbox. An extension is detachably fixed to the side of the main body near the gearbox, and the top of the extension is fixed to the side wall of the gearbox. The lock cylinder rotor is rotatably disposed between the gearbox and the lock cylinder sleeve. By using a U-shaped main body and a side wall horizontal fixing structure, the motor, gearbox, and lock cylinder rotor are arranged in a compact horizontal layout, completely breaking the traditional axial series mode. The axial length is shortened compared to existing technologies. The extension part can be detachably fixed to the side of the main body near the gearbox, and the top is directly fixed to the side wall of the gearbox. The lock cylinder rotor is rotatably set between the gearbox and the lock cylinder sleeve. The compact horizontal layout of each core component effectively shortens the overall axial length, adapting to the installation space limitations of miniaturized and thin smart locks, and breaking through the bottleneck of traditional structures being unable to adapt to small locks due to excessive length.

[0004] However, in existing technologies, the connection between the motor and the gearbox is a fixed-angle structure, which cannot flexibly adjust the relative angle according to actual installation requirements, and still has significant technical pain points: On the one hand, the internal space layout of different smart lock models varies greatly, and the processing of parts inevitably produces slight errors. The fixed-angle connection structure is difficult to adapt to these variables. It cannot fix the motor rotation angle to 45 degrees, 90 degrees, etc. according to space avoidance requirements, which can easily lead to interference between the motor and other internal components of the smart lock, increasing the difficulty of lock cylinder assembly; on the other hand, the fixed-angle design limits the adaptability of the lock cylinder. Manufacturers need to design special lock cylinders for different smart lock installation angle requirements, resulting in high production and adaptation costs, making it difficult to meet the market demand for diversified development of smart lock products.

[0005] Therefore, how to design a multi-angle adjustable connection structure between the motor and the gearbox while maintaining the existing structural compactness and connection stability, supporting the motor and gearbox to be fixed at multiple angles such as 45 degrees and 90 degrees, flexibly adapting to the spatial layout and power transmission requirements of different installation scenarios, avoiding assembly interference, and reducing adaptation costs has become a technical problem that urgently needs to be solved in the current field of smart lock technology. Utility Model Content

[0006] This utility model aims to solve one of the technical problems existing in the prior art.

[0007] This application provides a foldable motor lock core reducer structure, including a motor and a reduction gearbox, characterized in that an adjustable component is provided between the motor and the reduction gearbox for enabling the motor to rotate adjustablely relative to the reduction gearbox and to be fixed after rotating a certain angle.

[0008] Preferably, the adjustable component includes a fixed part connected to the gearbox, a mating part fixed to the motor, and a rotating bevel gear rotatably disposed on the fixed part. The output end of the motor is connected to a driving bevel gear. The mating part and the fixed part are rotatably connected. The input end of the gearbox is rotatably connected to a mating bevel gear. The driving bevel gear and the mating bevel gear are connected by a rotating bevel gear transmission. A control fixing component is disposed between the fixed part and the mating part.

[0009] Preferably, the control and fixing assembly includes a control hole on the mating part, a plurality of fixing holes on the fixing part, and a control bolt. When fixing, the control bolt passes through the control hole and is screwed into the fixing hole at the corresponding position to fix the mating part and the fixing part to each other.

[0010] Preferably, the mating part consists of a front splicing plate and a rear splicing plate. The rear splicing plate has a first hole on the side facing the gearbox for the mating bevel gear to pass through between the front and rear splicing plates. The fixing part has a second hole for the driving bevel gear to pass through between the front and rear splicing plates. A bevel gear seat is provided on the side wall of the front splicing plate facing the rear splicing plate, and the rotating bevel gear is rotatably mounted on the bevel gear seat. A folding shaft is provided on the side wall of the rear splicing plate away from the front splicing plate. The fixing part has a corresponding fixing rotation hole. During installation, after the front and rear splicing plates are fixed, the folding shaft is inserted into the fixing rotation hole, causing the mating part to rotate around the folding shaft relative to the fixing part.

[0011] Preferably, the front splicing plate is provided with splicing through holes, and the rear splicing plate is provided with corresponding splicing holes. The front splicing plate and the rear splicing plate are installed and fixed together by bolts through the splicing through holes and splicing holes.

[0012] Preferably, the rear splicing plate has several mating holes for the gearbox to be installed thereon, and the fixing part has several fixing holes for the motor to be installed thereon.

[0013] Preferably, a number of fixing holes are distributed around the folding pivot, and at least two fixing holes are respectively distributed on a line at a 90-degree angle relative to the folding pivot.

[0014] Preferably, the fixing part is provided with ear plates on the front and rear sides, wherein the fixing rotation hole and the control hole are provided on the rear ear plate, and the front ear plate is provided with auxiliary holes. The side wall of the front splicing plate away from the rear splicing plate is provided with auxiliary screw holes. After the fixing part and the mating part are installed and fixed by the control bolts, auxiliary fixing bolts are added at the auxiliary holes and auxiliary screw holes.

[0015] Preferably, the top of the side wall of the front splicing plate facing the rear splicing plate is provided with a top cover.

[0016] Preferably, the upper cover has an upper cover hole on the side wall away from the gearbox, and the rear splicing plate has a lower baffle on the side wall. The lower baffle has a lower baffle hole. When the motor and gearbox are in a parallel or perpendicular state after rotation, the internal rotating bevel gear of the fixing part and the mating part is covered with a baffle plate. The baffle plate has a baffle plate mounting hole. The baffle plate is fixed with a baffle bolt by mating with the upper cover hole or the lower baffle hole through the baffle plate mounting hole.

[0017] The aforementioned foldable motor lock cylinder reducer structure completely solves the adaptation limitations of existing fixed-angle structures. The motor installation angle can be flexibly adjusted according to the internal space layout of different smart locks—the 0-degree layout optimizes power transmission efficiency, while the 45-degree / 90-degree layout avoids interference with other components. At the same time, it compensates for component processing errors, reduces assembly difficulty, and adapts to the installation needs of diverse smart lock products.

[0018] Regardless of the angle of the motor and gearbox, the bevel gear and rotating bevel gear always maintain meshing transmission, ensuring continuous and uninterrupted power transmission. At the same time, the transmission structure is surrounded by the front and rear splicing plates, providing strong vibration resistance and avoiding meshing deviations caused by vibration, thus ensuring smooth unlocking.

[0019] The double locking mechanism of the auxiliary fixing bolts further enhances the connection strength, prevents angular displacement caused by vibration, and ensures long-term stability. This solution comprehensively addresses the core pain points of existing technologies, such as narrow compatibility, frequent assembly interference, and high production and adaptation costs due to the fixed angle between the motor and gearbox, while balancing flexibility, stability, and versatility.

[0020] The beneficial effects of this invention will be explained in detail in the embodiments, thereby making the beneficial effects more obvious. Attached Figure Description

[0027] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0028] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0029] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.

[0030] Example 1: like Figures 1-6 As shown, a foldable motor lock core reducer structure includes a motor 2 and a reduction gearbox 5. In a specific embodiment of this utility model, an adjustable component is provided between the motor 2 and the reduction gearbox 5 to enable the motor 2 to rotate adjustablely relative to the reduction gearbox 5 and to be fixed after rotating at a certain angle.

[0031] By adopting the aforementioned foldable motor lock core reducer structure, the limitations of existing fixed-angle connections are overcome. Through adjustable components, the motor 2 and the reducer 5 can achieve multi-angle relative rotation and fixation, providing basic structural support for subsequent adaptation scenarios such as 0 degrees, 45 degrees, and 90 degrees. This fundamentally solves the core pain points of smart lock assembly interference and narrow adaptation range.

[0032] In a specific embodiment of this utility model, the adjustable component includes a fixed part connected to the reduction gearbox 5, a mating part fixed to the motor 2, and a rotating bevel gear 101 rotatably disposed on the fixed part. The output end of the motor 2 is connected to a drive bevel gear 102. The mating part and the fixed part are rotatably connected. The input end of the reduction gearbox 5 is rotatably connected to a mating bevel gear 103. The drive bevel gear 102 and the mating bevel gear 103 are connected by a transmission through the rotating bevel gear 101. A control fixing component is provided between the fixed part and the mating part.

[0033] The combination of rotating bevel gear 101 and double bevel gear ensures that the motor 2 and the gearbox 5 can maintain stable meshing at any adjustment angle, and the power transmission is continuous and uninterrupted; the combination of rotating connection and control fixing components achieves the dual requirements of flexible adjustment and reliable fixing, taking into account both adaptability and transmission stability.

[0034] In a specific embodiment of this utility model, the control and fixing assembly includes a control hole 104 formed on the mating part, a plurality of fixing holes 105 formed on the fixing part, and a control bolt 106. When fixing, the control bolt 106 passes through the control hole 104 and is screwed into the fixing hole 105 at the corresponding position to fix the mating part and the fixing part to each other.

[0035] The control bolt 106 and the hole position are designed to be easy to operate and reliable to fix. It can accurately lock the adjusted angle and prevent the angle from shifting due to vibration during use. The design of several fixing holes 105 provides a basis for multi-angle fixing and adapts to different installation scenarios.

[0036] Example 2: The difference from Embodiment 1 is that, in addition to including the structural features of the aforementioned embodiments, in this specific embodiment of the present invention, the mating part is composed of a front splicing plate 107 and a rear splicing plate 108. The rear splicing plate 108 has a first hole 109 on the side facing the reduction gearbox 5 for the mating bevel gear 103 to pass through between the front splicing plate 107 and the rear splicing plate 108. The fixing part has a second hole 114 for the driving bevel gear 102 to pass through between the front splicing plate 107 and the rear splicing plate 108. A bevel gear seat 110 is provided on the side wall of the front splicing plate 107 facing the rear splicing plate 108. The rotating bevel gear 101 is rotatably mounted on the bevel gear seat 110. A folding pivot 111 is provided on the side wall of the rear splicing plate 108 away from the front splicing plate 107. A fixing pivot hole 112 is correspondingly provided on the fixing part. During installation, after the front splicing plate 107 and the rear splicing plate 108 are fixed, the folding pivot 111 is inserted into the fixing pivot hole 112 so that the mating part rotates around the folding pivot 111 relative to the fixing part.

[0037] The split design of the front and rear splicing plates facilitates the assembly and maintenance of the internal rotating bevel gear 101 and bevel gear; the cooperation between the folding shaft 111 and the fixed rotating hole 112 ensures smooth rotation without jamming and improves the convenience of angle adjustment; the bevel gear seat 110 provides a stable mounting reference for the rotating bevel gear 101 and reduces meshing deviation during transmission.

[0038] In a specific embodiment of this utility model, the front splicing plate 107 is provided with a splicing through hole 127, and the rear splicing plate 108 is provided with a corresponding splicing hole 113. The front splicing plate 107 and the rear splicing plate 108 are installed and fixed together by bolts through the splicing through hole 127 and the splicing hole 113.

[0039] The bolted splicing method ensures a firm connection between the front and rear splicing plates, guaranteeing the structural strength of the mating parts and preventing deformation during transmission; the detachable design facilitates the individual replacement of damaged splicing plates, reducing maintenance costs and simplifying the assembly process of internal components.

[0040] In a specific embodiment of this utility model, the rear splicing plate 108 is provided with a plurality of mating holes 115 for the gearbox 5 to be installed thereon, and the fixing part is provided with a plurality of fixing holes 116 for the motor 2 to be installed thereon.

[0041] like Figure 4 As shown, the fitting hole 115 and the fixing hole 116 are provided for matching and installation with the existing motor 2 and gearbox 5.

[0042] In a specific embodiment of this utility model, a plurality of fixing holes 105 are distributed around the folding pivot 111, and at least two fixing holes 105 are respectively distributed and opened at a 90-degree angle relative to the folding pivot 111.

[0043] The system ensures precise fixation of the critical 90-degree angle, meeting the most common parallel / vertical installation scenarios for smart locks. This scenario is applicable to the vast majority of motor lock cylinder installation scenarios. The hole distribution centered on the pivot ensures the uniformity and accuracy of angle adjustment, avoiding assembly problems caused by angle deviations.

[0044] In a specific embodiment of this utility model, ear plates 117 are provided on the front and rear sides of the fixing part, wherein the fixing rotation hole 112 and the control hole 104 are provided on the rear ear plate 117, and the front ear plate 117 is provided with an auxiliary hole 118. An auxiliary screw hole 119 is provided on the side wall of the front splicing plate 107 away from the rear splicing plate 108. After the angle is adjusted to the correct position, the mating part and the fixing part are installed and fixed by the control bolt 106, and then auxiliary fixing bolts 120 are added at the auxiliary hole 118 and the auxiliary screw hole 119.

[0045] An auxiliary fixing bolt 106 is added to the main fixing, forming a double locking structure, which further improves the connection strength and vibration resistance, and eliminates the risk of loosening after long-term use. The design of the ear plate 117 provides a more reasonable force structure for the fixing part, enhancing the overall stability. If the angle needs to be adjusted, first unscrew the auxiliary fixing bolt 120 and the control bolt 106 to unlock the mating part from the fixing part. Then, the motor 2 can be rotated flexibly around the folding shaft 111. After adjustment, the bolts are tightened again, making the operation convenient.

[0046] Example 3: The difference from Example 2 is that, as Figures 5-6 As shown, in addition to the structural features of the aforementioned embodiments, in a specific embodiment of this utility model, the top of the side wall of the front splicing plate 107 facing the rear splicing plate 108 is provided with a top cover 121.

[0047] The top cover 121 provides top protection for the internal rotating bevel gears 101, bevel gears and other transmission components, preventing dust and foreign objects from entering the meshing area, reducing wear, and extending the service life of the components; at the same time, it improves the structural integrity and aesthetics.

[0048] In a specific embodiment of this utility model, the upper cover 121 has an upper cover hole on the side wall away from the gearbox 5, and the rear splicing plate 108 has a lower baffle 122 on its side wall. The lower baffle 122 has a lower baffle hole 125. When the motor 2 and the gearbox 5 are in a parallel or perpendicular state after rotation, the fixed part and the mating part expose the internal rotating bevel gear 101 and are covered by a shielding plate 123. The shielding plate 123 has a shielding plate mounting hole 124. The shielding plate 123 is fixed with the upper cover hole or the lower baffle hole 125 through the shielding plate mounting hole 124 and the shielding bolt.

[0049] The shield 123 is a universal structure specifically designed to adapt to common installation scenarios of motor 2 and gearbox 5 at 0 degrees (parallel) and 90 degrees (perpendicular). 45 degrees is a special adaptation angle, in which the exposed area of ​​the transmission components is small, and in actual use, it is mostly for temporary debugging or adaptation in special spaces, so no additional shielding is required. This simplifies the structure without affecting the safety of use, and fully shields the exposed transmission structure, providing more comprehensive protection. The shield 123 is fixed by bolts through holes, making installation and disassembly convenient. It can fully shield the transmission structure exposed in parallel / perpendicular states, balancing protection and practicality.

[0050] In a specific embodiment of this utility model, three fixing holes 105 are provided, evenly distributed around the folding pivot 111. The included angle between adjacent fixing holes 105 is 45 degrees, with two holes corresponding to a 90-degree installation angle and the middle hole corresponding to a 45-degree installation angle, precisely matching the needs of different scenarios. This enables the following... Figure 5 The motor 2 and the gearbox 5 are fixed in a 45-degree rotation position.
