Description

Technical Field

[0001] This utility model relates to the field of drawers and automatic winding devices for mechanical watches, and in particular to a drawer that houses an automatic winding device for mechanical watches. Background Technology

[0002] The automatic winding mechanism of a mechanical watch, also known as an automatic winding box, automatic watch winder, or watch swinger, primarily uses a built-in motor to drive the entire mechanical watch to rotate, simulating the natural swinging motion of a person wearing the watch. This achieves automatic winding and mainspring rotation, ensuring the watch continues to run even when not worn. This type of automatic winding mechanism typically includes a box or enclosure. Taking the box as an example, its front is open, corresponding to an internal cavity. The opening is controlled by a hinged door or flip-up door, and the door itself features a fully or partially transparent window, allowing observation of the contents of the cavity. The automatic winding component for the mechanical watch is fixedly installed within the cavity, maintaining a suitable viewing distance from the opening and door. When viewed from the opening, the installation area of ​​the automatic winding component appears recessed. However, the automatic winding mechanism of this type of mechanical watch has the following shortcomings: 1) The automatic winding component is fixed in position and located on the inside, with a recessed layout. The user's view is easily blocked by the edge of the opening of the case. When taking out the watch, the user has to bend over or lower their head to operate it, which is not only uncomfortable to operate, but also inconvenient to use; 2) The door panel is repeatedly opened and closed, and its hinges and viewing window are prone to deformation and damage due to long-term wear, impact, collision, or uneven force, which affects the service life of the device; 3) The storage function is limited and can only be used to store mechanical watches. The expansion storage capacity is insufficient, and there is often a large amount of unused space behind the automatic winding component, which is not fully utilized and results in wasted space.

[0003] In addition, a Chinese utility model patent specification (publication number: CN222787320U) discloses a drawer cabinet with a watch winder, comprising: a cabinet body 1, a drawer body 2, and a watch winder. The cabinet body is provided with a partition 5, which divides the cabinet body into a drawer placement area and a watch winder placement area. That is, the drawer body can be installed in the area between the partition and the inner wall of the cabinet, or in the area between two partitions. Furthermore, the front side of the drawer body is provided with a decorative panel 202, on which a display window 7 is opened opposite the position of the watch winder, facilitating observation of the watch inside the winder. Although this drawer cabinet achieves a certain expansion of storage space, as can be seen from Figure 1 of the patent specification, the watch winder still adopts an inwardly recessed fixed installation design, and the installation position of the watch winder is directly opposite the decorative panel and the display window. This design has the following problems: 1) When taking out the watch, the user's view is still blocked by the side structure of the cabinet opening, requiring them to bend over or lower their head to operate, resulting in an uncomfortable operating posture; 2) The space between the watch winder placement area and the decorative panel is too cramped, making it easy for the hand or watch to collide or scratch with the edges of the decorative panel during the process of taking it out, which may not only cause hand injuries, but also scratch the watch case and crystal; 3) There is still a large amount of unused space at the back of the watch winder, which is a waste of space.

[0004] In view of this, the inventor, drawing on years of experience in the home furnishing industry, designed and optimized the product structure, and after numerous trials and improvements, created this invention. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model provides a drawer solution for loading the automatic winding component of a watch. By integrating the automatic winding component of the watch with the drawer, it moves and is exposed when the drawer is pulled out, making full use of space. At the same time, combined with the flip control structure, it eliminates the blind spot caused by the inner position of the automatic winding component during use, effectively improving the convenience of operation and the comfort of use, and overcoming the inherent display and opening method of traditional watch winders that rely on hinged doors or flip doors.

[0006] To achieve the above objectives, this utility model provides a drawer equipped with an automatic winding mechanism, comprising: a drawer body and its storage cavity, an automatic winding assembly, a flipping power device, and a rotating shaft mechanism. The automatic winding assembly includes a movable outer shell disposed within the storage cavity. The movable outer shell is provided with at least one watch base for placing a wristwatch and driven to rotate by the power device. The power output end of the flipping power device is connected to the movable outer shell, enabling the movable outer shell to flip upward to a preset angle in a horizontal state. The rotating shaft mechanism is symmetrically disposed on both sides of the movable outer shell, used to connect the movable outer shell to the storage cavity, allowing the movable outer shell to rotate using the rotating shaft mechanism as a support axis.

[0007] Compared to existing technologies, this invention integrates the automatic winding component of a mechanical watch with a drawer storage cavity. Utilizing the drawer's pull-out display and spatial extension features, the automatic winding component moves in and out synchronously with the drawer's movement, achieving convenient display and full exposure. Simultaneously, through the coordinated operation of the flipping power device and the rotating shaft mechanism, the automatic winding component can be controlled to flip upwards to a preset tilt angle within the drawer, presenting the component in an tilted display state and completely eliminating blind spots. This design provides users with more hand space when retrieving the mechanical watch, adjusting parameters, or observing the automatic winding component's operation, making operation more convenient and natural, and enhancing the overall user experience. It also fully utilizes the drawer's storage capabilities, making rational use of the unused space behind the automatic winding component and avoiding space waste. Furthermore, this drawer structure breaks away from the traditional reliance on hinged or flip-up doors for automatic winding devices, reducing the risk of wear, deformation, and collision damage to the door panel caused by repeated opening and closing, effectively extending the product's lifespan.

Detailed Implementation

[0016] To make the invention objective, technical solution and beneficial effects of this utility model clearer, the technical solution of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. However, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0017] like Figure 1 As shown, this embodiment is a drawer equipped with an automatic winding mechanism, which includes a drawer body 1. The drawer body is formed by a front panel 10, a back panel 7, two side panels 8, and a bottom panel 9, forming a storage cavity 11. An automatic winding assembly 3 is horizontally placed near the front of the storage cavity. An appropriate gap is maintained between the automatic winding assembly and the inner wall of the front panel. Through the cooperation of a flipping power device and a rotating shaft mechanism 2, the drawer can be flipped upwards within the storage cavity to a preset tilt angle to display the front, or returned to a horizontal state, thus achieving a back-and-forth switching function between the horizontal and flipped states. Furthermore, a crossbeam is fixed to the upper back of the front panel, with both ends of the crossbeam connected to the two side panels 8 for reinforcement.

[0018] The automatic winding assembly 3 is a component used to enable automatic winding of a mechanical wristwatch. It can be equipped with at least one or more watch holders 16 for holding the mechanical wristwatch and driven to rotate by a power unit. Each watch holder has a clamping structure that can be tightened or loosened, which can be adapted to clamp a watch cushion. This embodiment uses five watch positions as an example. The automatic winding assembly includes a rectangular movable housing 18, whose length is slightly shorter than the length of the storage cavity, allowing it to be inserted horizontally into the storage cavity 11. Simultaneously, installation gaps are reserved between the two sides of the movable housing and the side walls of the storage cavity for accommodating components such as the rotating shaft mechanism 2. The front of the movable housing has five watch positions evenly arranged in a straight line, and each watch position is equipped with a watch holder 16 driven to rotate by a drive motor. Each watch holder has a clamping function, which can stably clamp the corresponding watch cushion for placing the mechanical wristwatch. The automatic winding function of the mechanical wristwatch is then achieved through the rotational movement of the watch holder. In addition, a display screen 19 is installed on the top surface of the movable housing, which has functions such as status control, parameter adjustment, real-time monitoring, progress feedback, and abnormal indication. Alternatively, an operating knob (not shown in the figure) can be independently configured below each gauge position for independently controlling the speed and mode switching of the corresponding gauge. Furthermore, the display screen can also be located on the front of the movable housing.

[0019] The flipping power device is a power component used to drive the movable outer shell to achieve an upward flipping motion. In Embodiment 1, the flipping power device uses an electric cord reel 4, which is installed on the back panel 7 of the drawer body. Its structure is similar to that of existing clothes rack electric cord reels, clothes rack drive devices, and clothes rack lifting control mechanisms, including a housing, within which a single-axis motor, a transmission gear set, a winding reel, a control circuit, and an output port located at the end of the housing. The output shaft of the single-axis motor meshes with the driving gear of the transmission gear set. The surface of the winding wheel is provided with a winding groove and an external gear. A traction rope 17 is provided on the winding groove. The fixed end of the traction rope is fixed to the winding groove and is wound and stored on the groove surface with the fixed end as the starting end. Its free end extends out from the output port of the housing, and after passing through the guide assembly for support and direction change, it is fixed at the upper rear position of the left side of the movable housing 18 (Note: the left side is the left-hand direction when facing the view in the attached figure). This position serves as the force point for the movable housing to flip. The tension applied by the traction rope drives the movable housing to flip. The external gear of the winding wheel meshes with the output gear of the transmission gear set to transmit rotational power to the winding wheel. During operation, the power output by the single-axis motor is transmitted to the winding wheel through the transmission gear set, driving the winding wheel to rotate clockwise or counterclockwise, thereby realizing the winding and unwinding actions of the traction rope. When reeling in the line, the traction rope 17 generates traction force, pulling the movable outer shell 18 upward to a set tilt state; when releasing the line, the movable outer shell gradually loses traction force and slowly descends to its original position under its own gravity, restoring it to a horizontal state, thus completing a smooth transition between the horizontal and tilted states. The guide component used in this embodiment is a rolling guide structure, which includes two implementations: a roller type and a guide wheel type. In the roller type structure (not shown in the figure), this structure consists of a fixed shaft and a roller. The fixed shaft is vertically positioned at the upper left end of the drawer body's back panel, and the roller is fitted outside the fixed shaft and can rotate freely around it, forming a rolling guide structure. In the guide wheel type structure, the guide wheel 20 has a groove 21 around its circumference for the traction rope 17 to pass through, providing precise guidance and preventing slippage. The guide wheel's axis is supported and fixed by a wheel axle, and the wheel axle's installation and fixing position is set with reference to the fixed shaft of the roller type structure. The guide wheel can rotate freely around the wheel axle. Both of these rolling guide structures can replace sliding friction with rolling friction, reducing energy loss, significantly reducing wear on the traction rope, and further improving the smoothness of power transmission. In this embodiment, guide wheels 20 are used as guide components, which are fixed to the upper left end of the back panel of the drawer body by angle iron 22.

[0020] In another embodiment of the guide assembly (not shown in the figure), a smooth-surfaced rod structure is used, made of polished iron or stainless steel. The rod is vertically positioned at the upper left end of the drawer body's back panel, supported at its upper and lower ends by the top and bottom plates respectively, and fixedly connected to the back panel to ensure structural stability after installation. This rod design also allows for changing the output direction of the traction rope, guiding it along a predetermined trajectory. Simultaneously, the polished smooth surface reduces frictional resistance when the traction rope contacts the rod, minimizing wear and extending the service life of both the rope and the rod.

[0021] like Figure 2 As shown, in Embodiment 2 based on the electric reel as the flipping power device, the guide assembly adopts a rolling guide wheel 20 design (hereinafter referred to as the first guide wheel). The axis of the first guide wheel 20 is supported by a wheel axle, which is fixed to the upper left area of ​​the back panel of the drawer body by angle iron to ensure stable installation. In addition, a second guide wheel 25 is provided between the first guide wheel and the movable housing 18. The second guide wheel is installed in the installation gap between the left side of the movable housing and the side wall of the storage cavity 11, and is fixed to the upper part of the side wall of the storage cavity by its wheel axle. It can rotate freely around its wheel axle to realize the rolling guide function. When connected to the traction rope, the free end of the traction rope 17 passes through the first guide wheel and the second guide wheel in sequence and turns before being fixed to a preset fixed point (i.e., the force point) at the lower front end of the left side of the movable housing. This fixed point is located at the lower right corner of the left side of the movable housing (i.e., the lower front end of the side of the movable housing), which can form the farthest straight distance with the fulcrum of the shaft mechanism, thereby obtaining a suitable long lever arm. By employing dual guide wheels for coordinated guidance, the steering trajectory of the traction rope is precisely controlled, reducing frictional losses between the rope and components and lowering the power consumption of the electric reel. Simultaneously, the second guide wheel directs the force point to the lower front section of the movable housing, achieving a suitable and optimized power arm. This power arm, combined with the lever-saving characteristics of the second guide wheel and the rotational function of the shaft mechanism, effectively ensures uniform rotation speed and smooth, stable operation of the movable housing, while reducing the need for additional energy compensation, further improving the accuracy of power transmission and the stability of the device's operation. Simultaneously, it effectively avoids insufficient torque caused by the short lever arm needing to overcome frictional resistance and rotational inertia, preventing stuttering, jerking, poor smoothness, or unstable speed during the movable housing's start-up process.

[0022] like Figure 3As shown, in Embodiment 3, which uses the electric reel as the flipping power device, the difference from Embodiment 2 lies in the installation position and force logic of the second guide wheel: the second guide wheel 25 is installed at the upper left end of the rear of the movable housing 18, and is connected to one end of the movable swing arm 26 via an axle, allowing the second guide wheel to rotate freely around the axle on the movable swing arm. The other end of the movable swing arm is connected to a fixed point on the left side of the movable housing via an axle connection. This fixed point serves as the direct force point of the movable housing, enabling the second guide wheel to move synchronously with the movable housing 18 and swing up and down, always keeping the traction rope between the first guide wheel 20 and the second guide wheel in a horizontal traction state. When connected to the traction rope, the free end of the traction rope 17 passes sequentially around the first guide wheel 20 and the second guide wheel 25, and after turning, is fixed to a preset fixed point on the bottom plate of the drawer body. In this structural design, the second guide wheel serves as an indirect force-receiving point for the movable outer shell, located at the upper left end of the rear of the shell. The movable shell uses the rotating shaft mechanism 2 as its fulcrum. Based on the principle of leverage, when the electric reel winds up the cable, the guide rope applies an upward traction force to the movable shell via the second guide wheel, which is then transmitted to the direct force-receiving point of the shell. This traction force is ultimately converted into a flipping torque, driving the movable shell to smoothly flip upwards around the rotating shaft mechanism. Simultaneously, the rolling characteristics of the second guide wheel reduce friction and wear when the guide rope contacts the wheel, minimizing energy loss during power transmission and further ensuring the smoothness of the flipping motion and the accuracy of power transmission.

[0023] like Figure 4 As shown, in Embodiment 4, which uses the electric reel as the flipping power device, the problem of component protection when the movable housing gets stuck during flipping can be solved simultaneously. Specifically, when the movable housing gets stuck during flipping, if the traction force of the traction rope on the movable housing continues, the rigid load generated by the stuckness will directly impact the transmission chain of the flipping power device (including core components such as the motor, transmission gear set, and winding wheel), easily leading to damage to these components. Therefore, the guide assembly in this embodiment still uses the design and installation method of the aforementioned first guide wheel 20, while adding a first spring 27 between the force-bearing point of the traction rope 17 and the movable housing 18. This first spring is arranged in an arc shape along the contour surface of the rotating shaft mechanism 2, with its lower end fixed to a preset fixed point at the lower left side of the movable housing, and its upper end connected to the free end of the traction rope, thus forming a flexible buffer structure to buffer the traction force. When the traction rope exerts a traction force on the movable housing, the first spring undergoes elastic deformation and absorbs energy, constructing a flexible buffer zone between the traction rope and the movable housing, effectively dispersing instantaneous stress, thereby preventing the electric reel from being damaged by an excessive instantaneous rigid load.

[0024] The aforementioned first spring also applies to the dual-guide wheel structure of the electric cable reel, maintaining the same connection logic and buffering principle. Specifically, the free end of the traction rope passes around the first guide wheel and connects to one end of the second spring. The other end of the second spring is connected to the fixed end of a connecting rope. The free end of this connecting rope then passes around the second guide wheel and finally connects to a preset fixed point. This preset fixed point can be either the point where the movable outer shell experiences the flipping force or a fixed connection point pre-set on the bottom plate of the drawer body. Through this structural design, the traction force transmitted by the traction rope is buffered by the elasticity of the second spring, forming a flexible traction force. This also achieves a tension buffering effect, preventing the rigid load caused by jamming in the dual-guide wheel structure from directly impacting the flipping power device.

[0025] like Figure 1-4 As shown, the flipping power device further includes a second spring 24, which provides auxiliary power for the reset of the movable housing 18. The design of this second spring is applicable to any of the embodiments described above that use an electric reel as the flipping power device. The front end of the second spring is fixed to the bottom left side of the movable housing, while the rear end is fixed to the side wall of the storage cavity via a third connecting bracket 23. After installation, a downward elastic force can be applied to the movable housing. Through this second spring design, if the movable housing cannot smoothly return to its original position by its own weight after flipping, the elastic force of the second spring provides auxiliary pulling force to the movable housing. Simultaneously, in conjunction with the synchronous unwinding process of the electric reel, a synergistic force is formed, which can smoothly pull the movable housing back to its initial horizontal state along the rotating shaft mechanism, effectively avoiding the situation where it cannot return to its normal and smooth position.

[0026] Furthermore, the electric reel employs a dual-axis motor (not shown in the figure, but refer to the single-axis motor embodiment). Its housing has two corresponding output ports on both sides, a left output port and a right output port. This dual-axis motor is equipped with two synchronously operating output shafts. Each output shaft transmits rotational power to the winding wheel via a transmission gear set, driving the winding wheel to rotate and achieving synchronous release and retraction of the two traction ropes. Taking the above embodiment one as an example, when connected to the movable housing, the output ports at both ends of the electric reel simultaneously release or retract the traction ropes. The free ends of the two traction ropes, after being redirected by guide wheels in the corresponding output directions, are fixed to the upper rear positions on both sides of the movable housing, forming a symmetrical and synchronous traction structure. This ensures that the pulling force acts symmetrically and evenly on both sides of the housing. Compared to the single-motor output structure, the dual-motor electric reel can generate symmetrical and balanced pulling force on both sides of the movable housing, avoiding the problem of unilateral force offset, preventing the movable housing from jamming due to center of gravity shift during flipping, and avoiding structural deformation caused by long-term unilateral force, thus significantly improving operational stability. In addition, symmetrical force application can reduce the local load on the moving shell, rotating shaft and transmission components, reduce the accelerated wear of components caused by concentrated force, and significantly improve the service life of the entire device.

[0027] The aforementioned dual-axis motor design is also applicable to various embodiments of electric cable reels employing dual guide wheels or a first spring and a second spring. Its symmetrical traction logic is compatible with the functional principles of other components. For example, in embodiments adapted to a dual guide wheel structure (such as embodiments two and three): the left and right output shafts of the dual-axis motor are respectively connected to corresponding winding wheels, synchronously winding and unwinding two traction ropes. After adjusting their direction along the dual guide wheel guide paths on both sides (such as the first and second guide wheels on the left, and the first and second guide wheels on the right), the two traction ropes are symmetrically fixed to or pass through the force-bearing points of the movable housing (such as the preset fixing point at the lower front end of the movable housing side in embodiment two, and the second guide wheel at the upper rear end of the movable housing side in embodiment three). Furthermore, in embodiments with an added first spring (such as embodiment four): the dual-axis motor can synchronously wind and unwind the traction ropes on both sides, allowing the two traction ropes to adjust their direction along the guide components on both sides, and then connect to the first springs on the corresponding force-bearing paths on both sides, thereby allowing the traction ropes on both sides to synchronously generate a tension buffering effect, maintaining symmetrical buffering characteristics. Other embodiments employing symmetrical force-bearing structures follow the same principle and will not be elaborated further.

[0028] like Figure 5As shown, in Embodiment 5 of the flipping power device, the flipping power device adopts an electric push rod 28. This electric push rod is an electric drive device that converts the rotary motion of an electric motor into linear reciprocating motion, featuring direct transmission and precise control. When connected to the movable housing 18, the bottom end of the electric push rod is movably connected to the side wall of the storage cavity 11 via a shaft hinge through a third connecting bracket 23, allowing the electric push rod to swing flexibly around the bottom hinge point as the axis, adapting to the angle changes when the movable housing flips. The upper end of the electric rod is a telescopic push rod 29, with the top end of the telescopic push rod serving as a support point and having an assembly hole for connection. Correspondingly, a connecting plate 30 is fixed to the bottom of the left side of the movable housing. The surface of the connecting plate has a long strip-shaped guide groove 32, and a guide rod 31 passes through the guide groove, which can slide freely along the length of the guide groove. At the same time, one end of the guide rod is fixedly connected to the assembly hole of the telescopic push rod. When the electric actuator is in operation, the telescopic actuator reciprocates along the axial direction. Through the cooperation of the guide rod and the guide groove, the linear power is converted into a torque that pushes or pulls the movable outer shell, realizing a stable switching between the movable outer shell's horizontally retracted state and its flipped-out unfolded state. This electric actuator design not only provides direct and precise transmission but also simplifies component assembly and overall structure. Furthermore, its stable linear drive torque provides uniform power for the flipping and repositioning of the movable outer shell, improving the device's operational stability.

[0029] In other embodiments of the flipping power device, a non-electric gas strut and push-button latch combination structure can be used to mechanically drive the flipping and positioning of the movable outer shell. The implementation is similar to the electric push rod solution: the electric push rod is replaced with a gas strut. One end of the gas strut is movably connected to the side wall of the storage cavity via a hinged joint through a support base, and the other end is axially connected to the connecting plate at the bottom of the movable outer shell. This allows the gas strut to flexibly extend and retract as the flipping angle of the movable outer shell changes, always providing stable power support. Simultaneously, a set of push-button latches is added between the bottom of the movable outer shell and the bottom plate of the drawer body to lock the movable outer shell in a horizontal state, preventing it from being accidentally opened by the elastic force of the gas strut when not in use. In use, when the movable outer shell needs to be unfolded, pressing it down triggers the push-button latches to unlock, and the gas strut pushes the movable outer shell upwards to a preset unfolding angle using its own elastic extension force. If it needs to be reset from the flipped state, pressing the movable outer shell down to a horizontal state automatically engages the push-button latches, achieving a secure lock on the movable outer shell. The entire operation process only requires manual pressing to unlock and reset, without the need for additional power. The structure is simple and reliable, and it can be used in low-cost scenarios or where there is no power supply.

[0030] like Figure 1-6As shown, the pivot mechanism 2 is a support component that enables the movable outer shell to rotate within the drawer body, and can be applied to any of the above embodiments. This pivot mechanism mainly consists of an outer turntable 33 and an inner turntable 34. A slot is formed in the center of the axial end face of the outer turntable; this slot is designed as a countersunk hole 39 for the inner turntable to fit into the slot. After the inner turntable is fitted into the countersunk hole of the outer turntable, it can form a flexible relative rotational movement with the outer turntable. During installation, two pivot mechanisms 2 are provided and arranged symmetrically on the rearward side of the left and right sides of the movable outer shell 18. The outer turntable of each pivot mechanism is fixed to the corresponding side of the movable outer shell via a threaded assembly, and the inner turntable is fixed to the corresponding side wall of the storage cavity via a threaded assembly, thus forming a fixed rotation fulcrum. After this connection, the movable outer shell rotates within the drawer's storage cavity around the inner turntable as its axis.

[0031] Furthermore, the axial end face of the outer turntable 33 is provided with a notch 38 serving as a slide rail. This notch corresponds to and communicates with the countersunk hole 39, allowing the inner turntable to slide into the countersunk hole via the notch, completing the fitting assembly and achieving relative rotational movement. Simultaneously, to prevent the inner turntable from detaching from the countersunk hole, a matching limiting lock block 35 is also fitted at the notch. This limiting lock block allows the countersunk hole to form a closed-loop structure, thereby confining the inner turntable within the countersunk hole of the outer turntable and preventing radial loosening or detachment during rotation. In addition, when the limiting lock block is fitted, it is connected and fixed to the outer turntable using threaded components and connecting holes, facilitating quick installation, disassembly, and maintenance of the movable housing. Based on this structure, during the assembly of the movable outer shell, outer turntables need to be pre-installed at symmetrical positions on the left and right sides of the movable outer shell, and inner turntables are installed at corresponding positions on the side walls of the storage cavity 11. Then, the notches of the outer turntables on both sides of the movable outer shell are aligned with the inner turntables on the side walls of the storage cavity, and the movable outer shell is pushed so that the inner turntable slides into the countersunk hole of the outer turntable along the notch, completing the initial assembly and connection of the rotating shaft structure. Then, the limiting lock block is embedded in the notch and fixed with a threaded assembly, so that the countersunk hole forms a closed loop to lock the inner turntable. At this time, the movable outer shell can achieve a flipping movement under the support of the rotating shaft structure. If it is necessary to disassemble the movable outer shell, first remove the fixing threaded assembly of the limiting lock block and remove the limiting lock block; then pull the movable outer shell along the notch direction of the outer turntable so that the inner turntable slides out of the countersunk hole, and then the entire movable outer shell is pulled out of the storage cavity. The design of the notch on the outer turntable and the locking block allows for quick installation and disassembly of the movable outer shell. This not only makes operation convenient and assembly efficient, but also significantly reduces the difficulty of later maintenance, providing convenience for equipment maintenance.

[0032] Furthermore, the limiting lock block 35 has a limiting groove 37 in the shape of a concave arc on its inner side facing the inner turntable; correspondingly, a protruding part 36 is provided on the circumferential contour surface of the inner turntable. This protruding part is placed within the concave arc range of the limiting groove and can move along the groove, forming a mutually constraining structure with the limiting groove. Through the combined design of the limiting groove and the protruding part, the rotation stroke of the rotating shaft mechanism can be effectively constrained, thereby limiting the relative rotation amplitude between the inner and outer turntables and ensuring that the movable housing rotates within a set angle range; at the same time, the two can also play a supporting and positioning role. When the movable housing returns to the horizontal state, the protruding part will fit tightly with one end of the limiting groove to form a stable support point, keeping the housing horizontal and not wobbling; in addition, this structure can also prevent the movable housing from touching the drawer bottom plate due to excessive tilting or generating abnormal stress with related components, thereby preventing problems such as wear, deformation or even breakage of components.

[0033] Furthermore, two trigger-type limit switches are also provided at the rear of the movable housing, namely the first limit switch 14 and the second limit switch 15. Both limit switches are micro switches, which are fixed to the left side wall of the storage cavity via the first connecting bracket 12 and the second connecting bracket 13, respectively. The first limit switch is located directly below the second limit switch, and its pressing spring contacts the lower part of the rear plate of the movable housing 18. When the movable housing is in a horizontal state, the lower part of its rear plate will press down on the actuating spring of the first limit switch, triggering the switch contacts to cut off the motor circuit of the flipping power device and stop its operation. The second limit switch is fixed at an angle on the second connecting bracket 13, and its pressing spring contacts the upper part of the rear plate of the movable housing. When the movable housing is flipped to a set angle and is in an inclined state, the upper part of its rear plate presses down on the actuating spring of the second limit switch, triggering the switch contacts to stop the motor of the flipping power device. The design of these two limit switches provides dual limits for the flipping and resetting travel of the movable housing, ensuring timely stopping and preventing overload damage to the drive system and component detachment caused by the motor continuing to run when the movable housing is stuck or exceeds the constraint range. Furthermore, the aforementioned limit switch design is also applicable to various drive devices with motors.

[0034] Furthermore, the drawer containing the automatic winding device also includes a controller 6, see... Figure 1 The controller is installed on the back panel 7 of the drawer body and is electrically connected to the motor-driven tilting mechanism via a wire, allowing direct control of the motor's operation. The controller integrates three functional switch modules: a sensor switch module, a voice-activated switch module, and a remote control switch module. These modules can control the motor of the tilting mechanism to start using different triggering methods, meeting diverse operational needs. 1) In the sensor switch module, see... Figure 4 , Figure 51) The sensing element A is set on the surface of the movable shell, or it can be set on the crossbeam of the drawer body. When the user touches the sensing area, the module will immediately trigger a signal to control the motor of the flipping power device to start, thereby driving the movable shell to complete the flipping or resetting movement; 2) In the voice-controlled switch module, its sound sensor (i.e., the microphone as the sound signal receiving unit) is fixed on the inside of the front of the drawer. Before use, the start words need to be pre-recorded. When the sound sensor receives the sound signal and recognizes the correct preset words, it will automatically send a start command to the drive device to drive the movable shell to flip or reset; 3) In the remote control switch module, it includes an infrared or Bluetooth signal transceiver unit, which can be paired with the matching wireless remote control. After the user sends a command through the operation button on the remote control, the module receives the command and converts it into a control signal to start the motor of the flipping power device, thereby realizing the remote control flipping or resetting movement of the movable shell. In addition, the controller's switch module can be configured individually with any one of the three modules mentioned above, depending on the product's functional positioning and usage scenario requirements. Alternatively, any two or three modules can be combined (such as "sensor + remote control", "voice control + sensor", etc.) to further enhance the ease of operation and adaptability, meeting the needs of users with different requirements.

[0035] like Figure 1-5 , Figure 7 As shown, the drawer body 1 further includes a reserved independent storage space 44 located at and adjacent to the rear of the movable outer shell 3. Various storage boxes can be placed directly inside this space for convenient categorized storage of items. Alternatively, detachable dividers can be added to accommodate different sized items by flexibly adjusting the spacing between them. Furthermore, the size, space occupied, and installation position of the movable outer shell within the storage cavity can be flexibly adjusted. The storage space can be positioned at the front of the movable outer shell, on its side, or in a semi-enclosed layout around it, maximizing the overall storage space utilization while maintaining functionality and practicality.

[0036] Furthermore, the front of the drawer body 1 is equipped with a viewing window, which is positioned directly opposite the watch position of the automatic winding component. The viewing window adopts a combination structure design of a light-transmitting panel 43 and a frame, thus forming the front panel 10 of the drawer; in addition, this front panel can also adopt a frameless light-transmitting panel design; the light-transmitting panel can be made of glass or plexiglass, and its size can be flexibly designed according to the number of watches or the required viewing range. Through this viewing window, users can intuitively and clearly observe the status of the stored watches, the operation of the automatic winding component, and related parameters without opening the drawer, improving the convenience and aesthetics of use.

[0037] Furthermore, a protective cover 48 is provided on the left side of the storage compartment. This protective cover can shield and protect components such as the traction rope, the second spring, the connecting frame, the limit switch, and the electric push rod. This not only prevents these components from being exposed to dust or damaged by external impacts, but also makes the internal structure of the drawer neater and more organized.

[0038] Furthermore, the aforementioned drawer equipped with an automatic winding device also includes an outer casing 40, a drawer lock device 5, and its unlocking control module 42. The outer casing is fitted entirely onto the drawer body 1, with a pre-drilled opening on its front, allowing the drawer body to be pulled out along this opening. The inner sidewalls of the drawer body on both sides are connected to the corresponding inner sidewalls of the outer casing via a linear guide rail mechanism, enabling smooth directional pulling of the drawer body under the guidance of the rails. Additionally, the linear guide rail mechanism can also be located between the bottom of the drawer body and the bottom plate of the outer casing.

[0039] The drawer lock device 5 is located at the rear of the drawer body and is used for locking and unlocking the drawer body and the outer box. This drawer lock device generally includes a lock body and a lock rod. The lock body consists of a lock seat and a cover plate. The lock seat has a lock groove facing the lock rod, and a locking block, a stop support rod, and a drive motor are provided on the surface of the lock seat. The locking block and the stop support rod are mounted on the base surface via shafts and torsion springs, respectively, allowing for rotation and elastic reset. The locking block has a locking hook corresponding to the lock rod, and a first locking portion and a second locking portion located on its outer contour surface. The locking hook also has an outwardly extending pushing portion. The head of the stop support rod can alternately abut between the first and second locking portions, thereby controlling the opening and closing of the locking hook of the lock block. The output shaft of the drive motor is connected to a lever, which contacts the tail of the stop support rod, pushing the stop support rod to swing, causing its head to switch from the second locking portion to the first locking portion and abut, thus unlocking. The lock rod can be either fixed or movable. In the fixed structure, the locking bar is fixed to the rear end of the outer box via a "C"-shaped bracket and aligned with the lock groove. When the locking bar is pushed by the lock hook and hooked, it is locked in the lock groove. At this time, the head of the stop support rod switches from the first locking part to the second locking part and abuts against it. In the sliding structure, the locking bar is fixed to the sliding seat of the sliding bracket via a "C"-shaped bracket and slides synchronously with the sliding seat. At the same time, a compression spring is provided between the rear of the drawer body and the outer box. When the lock body is unlocked, the compression spring can automatically push the drawer body out. This sliding locking bar solution is suitable for scenarios where the fingerprint password control module is located on the top surface of the front of the drawer. The structural design of the drawer lock device in this embodiment can also refer to relevant patent solutions in the prior art, specifically including: "A fingerprint drawer lock" disclosed in the Chinese Utility Model Patent Specification (Announcement No.: CN205445192U), "A drawer-type safe electronic lock" disclosed in the Chinese Utility Model Patent Specification (Announcement No.: CN210264250U), and "Drawer-type safe and its locking device" disclosed in the Chinese Utility Model Patent Specification (Announcement No.: CN205577660U).

[0040] Furthermore, the unlocking control module 42 supports a touch panel component for fingerprint and digital password input. This touch panel component is electrically connected to the drawer lock device via a control circuit, and can transmit unlocking signals in real time to trigger the locking or unlocking action of the lock body. The touch panel component is located on the top surface of the front end of the drawer body and can be hidden or revealed as the drawer is pulled out; in another embodiment, the touch panel component is directly fixed to the front surface of the outer box, allowing for unlocking without pulling out the drawer. Through the unlocking control module, users can achieve fingerprint or digital password unlocking of the drawer.

[0041] Furthermore, the unlocking control module 42 is fixed at the upper center of the front of the outer box. A drawer slot 45 is located on each side of the unlocking control module, and each drawer slot contains an independent small drawer 41. The bottom of the small drawer is connected to the corresponding side wall of the drawer slot via a ball bearing slide, allowing the small drawer to slide smoothly out of the drawer slot. The added small drawers expand the overall storage space of the drawer box, facilitating the categorization and storage of small items, and improving the practicality and flexibility of storage. In addition to ball bearing slides, bounce slides or a slide-less design can also be used.

[0042] Furthermore, a groove is provided on the front side wall of the left drawer slot, with an inclined surface 46 inside, facing the opening of the drawer slot 45. A spare mechanical lock 47 is installed on the inclined surface, and the rear end of the lock cylinder of the mechanical lock is connected to the stop support rod of the drawer lock device via a pull rope. In use, rotating the lock cylinder with the key can pull the stop support rod to disengage from the lock block, realizing the mechanical unlocking function. This design can effectively deal with the sudden situation of failure of the electronic control part, ensuring that the drawer can be opened normally. At the same time, compared with the design of installing it on the back of the outer box, the spare mechanical lock can be operated without moving the drawer cabinet, making it more convenient to use. In addition, the mechanical lock is hidden in the groove of the left drawer slot, and is concealed by the drawer body, which enhances its privacy and further improves the security of the product.
