Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and more specifically, to a rotating cabinet. Background Technology

[0002] Storage cabinets are primarily used for convenience, providing storage for various items. For smaller homes or dormitories, storage cabinets make the most of space, accommodating a greater number of belongings and also enhancing the home's aesthetics. Corner cabinets, a type of storage cabinet, are fixed to a corner, utilizing corner space for storage and effectively maximizing room storage capacity.

[0003] The prior art (application number: 202411774858.3, application date: 2024.12.05) discloses a rotating cabinet track-guided rotating structure, including a movable plate 1', a fixed plate 2' with the same area as the movable plate 1', a rotating assembly 3' located between the movable plate 1' and the fixed plate 2' and respectively assembled with the movable plate 1' and the fixed plate 2', the rotating assembly 3' including two linear tracks that are parallel and fixedly installed on the fixed plate 2' and have grooves, a damper disposed inside the two linear tracks and fixedly installed with the fixed plate 2', and a rotating seat whose upper end is movably assembled with the movable plate 1' and whose lower end is movably assembled with the linear tracks and the damper, the rotating seat including a rotating seat body and a fixed bearing embedded in the central part of the rotating seat body. The shaft head, which is installed in conjunction with the fixed bearing and assembled with the movable plate 1', is fixedly mounted on the support blocks below both ends of the rotating base body by screws. Several rolling pulleys, which are installed below the support blocks by fixed shafts and inserted into the internal grooves of the linear track, and two claws, which are symmetrically mounted on one side of the rotating base body by screws and abut against the pull hooks of the damper, are also present. The movable plate 1' has an arc-shaped rotating guide groove 11' welded on its surface facing the fixed plate 2'. The movable plate 1' also has a shaft head mounting hole 12' for assembling the shaft head at its center point. A positioning guide post 21' is fixedly mounted on one corner of the fixed plate 2' facing the movable plate 1' by screws. In the above scheme, the shaft head is directly mounted on the fixed bearing and then inserted into the shaft head mounting hole 12'. When the rotating cabinet rotates, there are problems such as poor stability, manual operation, easy loosening, troublesome maintenance, and high replacement cost.

[0004] Therefore, the urgent need to provide a rotating cabinet that is stable, requires no manual operation, is not easily loosened, is easy to maintain, and reduces costs is a technical problem that needs to be solved in this field. Utility Model Content

[0005] In view of this, the present invention provides a rotating cabinet to solve the problems of the prior art where the shaft head is directly mounted on the fixed bearing and then inserted into the shaft head mounting hole. When the rotating cabinet rotates, it has poor stability, is manually operated, is prone to loosening, is troublesome to maintain, and has high replacement costs.

[0006] This utility model provides a rotating cabinet, including a fixed cabinet body, a rotating cabinet body, an upper arc-shaped track mechanism, and a lower arc-shaped track mechanism, wherein...

[0007] The fixed cabinet includes a parallel fixed top plate assembly and a fixed bottom plate assembly; the rotating cabinet is located inside the fixed cabinet and includes a rotating top plate assembly corresponding to the fixed top plate assembly and a rotating bottom plate assembly corresponding to the fixed bottom plate assembly; the upper arc-shaped track mechanism connects the fixed top plate assembly and the rotating top plate assembly, and the lower arc-shaped track mechanism connects the fixed bottom plate assembly and the rotating bottom plate assembly.

[0008] Both the upper arc-shaped track mechanism and the lower arc-shaped track mechanism include an arc-shaped track component, a linear track component, and a slider bearing component, wherein...

[0009] The arc-shaped track component includes a first track plate, an arc-shaped track, and a guide component. The arc-shaped track is connected to the side of the first track plate away from the rotating cabinet. The guide component includes a guide post and a guide shaft fixedly connected to the guide post. The guide post is fixedly connected to the midpoint of the side of the first track plate away from the rotating cabinet. The side of the guide post near the first track plate is a cylinder or a polyhedron.

[0010] The linear track component includes a second track plate, a drive unit, a linear track, and a positioning unit. The drive unit and the linear track are respectively connected to the side of the second track plate near the first track plate. The positioning unit includes a hollow positioning post, a gear shaft, a bevel gear, and a spur gear. The hollow positioning post is fixedly connected to the top corner of the second track plate near the first track plate. The gear shaft is sleeved inside the hollow positioning post near the first track plate. The spur gear is located on the side of the bevel gear away from the hollow positioning post. The bevel gear and the spur gear are welded together and rotatably connected to the gear shaft through a gear bearing. The tooth surface of the bevel gear faces the side of the second track plate. There are two linear tracks, and the drive unit is located between the two linear tracks.

[0011] An arc-shaped rack is provided on the side of the arc-shaped track away from the first track plate, and the tooth surface of the arc-shaped rack faces the guide shaft; the spur gear meshes with the arc-shaped rack, and the rotation of the gear shaft drives the spur gear to move along the arc-shaped trajectory of the arc-shaped rack; the driving component includes a motor and a driving rod connected to the motor, and the side of the driving rod away from the motor is provided with gear teeth that match the bevel gear, and the bevel gear meshes with the gear teeth;

[0012] The slider bearing component includes a slider bearing plate, a fixed bearing, and a linear track slider. The slider bearing plate is provided with the linear track slider matching the linear track on the side near the second track plate. The linear track slider is slidably connected to the linear track. The motor drives the linear track slider to perform reciprocating linear motion on the linear track through the drive rod. The fixed bearing is provided on the side of the slider bearing plate away from the second track plate. The guide shaft is rotatably connected to the fixed bearing.

[0013] Compared with the prior art, the rotating cabinet provided by this utility model achieves at least the following beneficial effects:

[0014] First, the direct fixed connection between the guide component and the first track plate in this utility model not only enhances the rigidity of the overall structure, reduces swaying, improves the stability of the rotating cabinet, and reduces the risk of loosening or wear, extending its service life, but also allows for easy replacement of the guide component when it is damaged, reducing costs and facilitating maintenance. Furthermore, it ensures the alignment accuracy between the first track plate and the guide component, reducing errors and making the rotating cabinet operate more smoothly. In addition, it reduces installation steps, lowers installation difficulty, and saves time and labor costs.

[0015] Secondly, through the coordination between the arc-shaped track components, the linear track components, and the slider bearing components, the synchronization of linear and arc-shaped motions in the upper and lower arc-shaped track mechanisms is achieved. For example, the driving component drives the linear track slider, causing the slider bearing plate to move along the linear track; at the same time, the cooperation between the arc-shaped track and the positioning component realizes the arc-shaped motion.

[0016] Third, through the cooperation of a motor, an arc-shaped rack, bevel gears, spur gears, and a drive rod, a combination of linear and arc-shaped motion between the fixed and rotating cabinets is achieved. For example, the motor drives the drive rod, which meshes with the bevel gear through its teeth, transmitting power to the spur gear. The spur gear meshes with the arc-shaped rack, driving the arc-shaped track component to move along the linear track. The linear track slider is slidably connected to the linear track, and the arc-shaped track moves along an arc-shaped trajectory based on the gear shaft. During the movement, because the position of the gear shaft is fixed, the distance between the arc-shaped track and the fixed bearing changes during the movement of the arc-shaped trajectory. During the distance change, the linear track slider is driven to perform reciprocating linear motion on the linear track. The guide component is connected to the fixed bearing, and the arc-shaped track component on the first track plate rotates around the guide component. The slider bearing plate connects the fixed bearing and the linear track slider, ensuring that the linear track slider slides smoothly on the linear track while supporting the rotational movement of the arc-shaped track component. The above structure does not require manual operation, improving power transmission efficiency, motion accuracy, and stability, and is suitable for scenarios requiring complex motion trajectories and high-precision control.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all the technical effects described above at the same time.

[0042] The fixed cabinet 1 includes a parallel fixed top plate assembly 11 and a fixed bottom plate assembly 12; the rotating cabinet 2 is located inside the fixed cabinet 1, and includes a rotating top plate assembly 21 corresponding to the fixed top plate assembly 11 and a rotating bottom plate assembly 22 corresponding to the fixed bottom plate assembly 12; an upper arc-shaped track mechanism 3 connects the fixed top plate assembly 11 and the rotating top plate assembly 21, and a lower arc-shaped track mechanism 4 connects the fixed bottom plate assembly 12 and the rotating bottom plate assembly 22; both the upper arc-shaped track mechanism 3 and the lower arc-shaped track mechanism 4 include an arc-shaped track component 41, a linear track component 42, and a slider bearing component 43, wherein...

[0043] The arc-shaped track component 41 includes a first track plate 410, an arc-shaped track 411, and a guide component 412. The arc-shaped track 411 is connected to the side of the first track plate 410 away from the rotating cabinet 2. The guide component 412 includes a guide post 4121 and a guide shaft 4122 fixedly connected to the guide post 4121. The guide post 4121 is fixedly connected to the midpoint of the side of the first track plate away from the rotating cabinet. The side of the guide post 4121 closest to the first track plate 410 is a cylinder or a polyhedron.

[0044] The linear track component 42 includes a second track plate 420, a driving component 421, a linear track 422, and a positioning component 423. The driving component 421 and the linear track 422 are respectively connected to the side of the second track plate 420 near the first track plate 410. The positioning component 423 includes a hollow positioning post 4231, a gear shaft 4232, a bevel gear 4233, and a spur gear 4234. The hollow positioning post 4231 is connected to the apex corner of the second track plate 420 near the first track plate 410. A gear shaft 4232 is fitted inside the positioning post 4231 on the side near the first track plate 410. A spur gear 4234 is located on the side of the bevel gear 4233 away from the hollow positioning post 4231. The bevel gear 4233 and the spur gear 4234 are welded together and rotatably connected to the gear shaft 4232 through a gear bearing 4235. The tooth surface of the bevel gear 4233 faces the side of the second track plate 420. There are two linear tracks 422, and the driving component 421 is located between the two linear tracks 422.

[0045] An arc-shaped rack 413 is provided on the side of the arc-shaped track 411 away from the first track plate 410, with the tooth surface of the arc-shaped rack 413 facing the guide post 4121; a spur gear 4234 meshes with the arc-shaped rack 413, and after the gear shaft 4232 rotates, it drives the spur gear 4234 to move along the arc-shaped trajectory of the arc-shaped rack 413; the driving component 421 includes a motor 4211 and a driving rod 4212 connected to the motor 4211, with a gear tooth 426 matching the bevel gear 4233 on the side of the driving rod 4212 away from the motor 4211, and the bevel gear 4233 meshes with the gear tooth 426;

[0046] The slider bearing component 43 includes a slider bearing plate 431, a fixed bearing 432, and a linear track slider 433. The slider bearing plate 431 is provided with a linear track slider 433 that matches the linear track 422 on the side closer to the second track plate 420. The linear track slider 433 is slidably connected to the linear track 422. The motor 4211 drives the linear track slider 433 to reciprocate linearly on the linear track 422 through the drive rod 4212. The fixed bearing 432 is provided on the side of the slider bearing plate 431 away from the second track plate 420. The guide shaft 4122 is rotatably connected to the fixed bearing 432.

[0047] Specifically, this rotating cabinet is a cabinet that can rotate to optimize space utilization and improve the ease of accessing items. It features a swivel or rotating motion and can be used in kitchens, laboratories, and offices to store tools, equipment, or documents.

[0048] Combination Figure 2 and Figure 13 As shown, the aforementioned fixed cabinet 1 is a hollow, side-opening cuboid structure, comprising a fixed top plate assembly 11 and a fixed bottom plate assembly 12. The fixed top plate assembly 11 and the fixed bottom plate assembly 12 are parallel to each other and can each be an L-shaped three-dimensional structure. This fixed cabinet 1 serves as an outer cabinet and is immovable, meaning it cannot rotate, thus providing structural support and protection for the rotating cabinet 2. The fixed top plate assembly 11 and the fixed bottom plate assembly 12 serve as the static support structure for the rotating cabinet.

[0049] Combination Figure 2 and Figure 14 As shown, the rotating cabinet 2 matches the fixed cabinet 1. The rotating cabinet 2 can also be a hollow cuboid structure with side openings, located inside the fixed cabinet 1. The rotating cabinet 2 includes a rotating top plate assembly 21 and a rotating bottom plate assembly 22. The rotating top plate assembly 21, the fixed top plate assembly 11, the fixed bottom plate assembly 12, and the rotating bottom plate assembly 22 are parallel to each other. The rotating top plate assembly 21 is closer to the fixed top plate assembly 11, and the rotating bottom plate assembly 22 is closer to the fixed bottom plate assembly 12. The rotating top plate assembly 21 and the rotating bottom plate assembly 22 can each be an L-shaped three-dimensional structure. The rotating cabinet 2 can be an inner cabinet that rotates smoothly relative to the outer cabinet.

[0050] The upper arc-shaped track mechanism 3 connects the fixed top plate assembly 11 and the rotating top plate assembly 21, allowing the rotating top plate assembly 21 to move in an arc. The rotating top plate assembly 21 slides on the upper arc-shaped track mechanism 3, achieving a 180-degree rotation (such as clockwise or counterclockwise). The lower arc-shaped track mechanism 4 connects the fixed bottom plate assembly 12 and the rotating bottom plate assembly 22, allowing the rotating bottom plate assembly 22 to move in an arc. The rotating bottom plate assembly 22 slides on the lower arc-shaped track mechanism 4, achieving a 180-degree rotation (such as clockwise or counterclockwise). The upper arc-shaped track mechanism 3 and the lower arc-shaped track mechanism 4 work together to ensure that the rotating top plate assembly 21 and the rotating bottom plate assembly 22 move synchronously and maintain structural stability.

[0051] Continue to refer to Figure 2 As shown, both the upper arc-shaped track mechanism 3 and the lower arc-shaped track mechanism 4 include an arc-shaped track component 41, a linear track component 42, and a slider bearing component 43, wherein...

[0052] Combination Figure 2 , Figure 3 , Figures 5-8As shown, the arc-shaped track component 41 includes a first track plate 410, an arc-shaped track 411, and a guide component 412. The first track plate 410 has a rectangular shape and serves as the basic support structure for the arc-shaped track component 41. The arc-shaped track 411 is fixedly connected to the first track plate 410 on the side closest to the first track plate 410, and the arc-shaped track 411 is located on the side of the first track plate 410 away from the rotating cabinet 2. The head and tail ends of the arc-shaped track 411 are located at two diagonal positions of the first track plate 410, and the arc-shaped track 411 is arranged along the diagonal direction.

[0053] It should be noted that the two ends of the arc track 411 are the rotation termination points, i.e. limit points, in the 180-degree rotation direction. Based on the 180-degree clockwise or counterclockwise rotation, the two ends of the arc track 411 are symmetrical and are located on the diagonal of the first track plate 410.

[0054] The midpoint of the side of the first track plate 410 away from the rotating cabinet 2 is fixedly connected to the guide post 4121. The guide post 4121 is located on the side of the first track plate 410 away from the rotating cabinet 2. The guide post 4121 can be a hollow guide post or a solid guide post. The guide shaft 4122 is welded to the side of the guide post 4121 near the guide shaft. If the guide shaft 4122 is a cylinder, when the guide post is a hollow guide post, one end of the guide shaft 4122 is inserted into the hollow part of the guide post 4121, and its circumferential surface is fixed to the joint surface of the hollow part of the guide post 4121 by circumferential welding. The guide post can be a cylinder or a polyhedron. Polyhedra include regular polyhedra (such as regular tetrahedrons and regular octahedrons), prisms (such as regular hexagonal prisms), and pyramids (such as triangular pyramids). When the guide post 4121 adopts a polyhedral design, it is beneficial to effectively fix it to the first track plate 410, and more effectively reduce the shaking of the rotating cabinet during the movement. This embodiment uses a cylinder as an example only.

[0055] Inventors in this field have verified and summarized their experience through multiple trials. Existing technologies disclose a rotating cabinet track-guided rotating structure, in which the shaft head is directly fixed on a fixed bearing and then inserted into the shaft head mounting hole. During rotation, this structure suffers from poor stability, easy loosening, troublesome maintenance, and high replacement costs.

[0056] In this embodiment, since the guide post 4121 of the guide member 412 is directly fixed to the midpoint of the side of the first track plate 410 away from the rotating cabinet 2, the guide post 4121 of the guide member 412 is directly fixed to the midpoint of the first track plate 410, which ensures uniform force distribution, reduces the shaking of the rotating cabinet during movement, improves overall stability, and avoids loosening caused by frequent movement, thus enhancing the reliability of the rotating cabinet. At the same time, the connection between the guide member 412 and the first track plate 410 is simple and firm. During maintenance, only the guide member 412 and its connecting parts need to be inspected or replaced, without disassembling other complex components, which reduces the difficulty of maintenance.

[0057] Optionally, along the direction from the fixed top plate group 11 to the fixed bottom plate group 12, the orthographic projection of the arc track 411 and the orthographic projection of the guide member 412 do not overlap at all, so as to ensure that the movement trajectory of the arc track 411 and the movement trajectory of the guide member 412 do not interfere with each other. For example, the arc track 411 is used to realize rotational movement, while the guide member 412 realizes linear and arc movement. That is, the orthographic projection of the arc track 411 and the orthographic projection of the guide member 412 do not overlap at all, which can ensure that their movement trajectories are independent of each other, thereby realizing more complex movement functions. In addition, the above design can also make more reasonable use of space and avoid the structure being too complex.

[0058] Combination Figure 2 , Figure 3 , Figure 4 , Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, the linear track component 42 includes a second track plate 420, a drive component 421, a linear track 422, and a positioning component 423. The overall shape of the second track plate 420 matches that of the first track plate 410. For example, the overall shape of the second track plate 420 is also rectangular, meaning that both the first track plate 410 and the second track plate 420 are rectangular. The second track plate 420 serves as the basic support structure for the linear track component 42, and is used to install the drive component 421, the linear track 422, and the positioning component 423. The drive component 421 is used to control the movement of the linear track 422, and is connected to the side of the second track plate 420 closest to the first track plate 410. The linear track 422 provides a linear motion trajectory, enabling the second track plate 420 to move along a straight line, and is connected to the side of the second track plate 420 closest to the first track plate 410.

[0059] The hollow positioning post 4231 is fixed to the top corner of the second track plate 420, and a gear shaft 4232 is installed inside it. The gear shaft 4232 serves as the rotational support shaft for the spur gear 4234 and the bevel gear 4233. The spur gear 4234 and the bevel gear 4233 are machined separately and then joined together as a whole by friction welding. Subsequently, a gear bearing 4235 is installed, which is rotatably connected to the gear shaft 4232. For example, the inner ring of the gear bearing 4235 is interference-fitted with the gear shaft 4232, and the outer ring of the gear bearing 4235 is clearance-fitted with the spur gear 4234 and the bevel gear 4233 to ensure free rotation. The gear bearing 4235 can reduce friction and ensure smooth rotation of the spur gear 4234 and the bevel gear 4233. The side of the gear shaft 4232 away from the hollow positioning post 4231 abuts against the arc-shaped track 411.

[0060] The driving component 421 drives the gear teeth 426 on the drive rod 4212 to mesh with the bevel gear 4233, causing the bevel gear 4233 to rotate. The bevel gear 4233 connects with the spur gear 4234, causing the spur gear 4234 to rotate accordingly. The spur gear 4234 meshes with the arc-shaped rack 413, driving the arc-shaped track component 41 to move along the straight track 42, enabling the second track plate 420 to move in a straight line. The linear motion and arc-shaped motion work together to enable the second track plate 420 to achieve complex motion trajectories. While the second track plate 420 is moving in a straight line, the gear shaft 4232 in the positioning component 423 moves along the arc-shaped track 411, causing the second track plate 420 to produce arc-shaped motion. The driving component 421, the straight track 422, and the positioning component 423 are concentrated on the side of the second track plate 420 near the first track plate 410, making the structure more compact and facilitating installation and maintenance.

[0061] There are two linear tracks 422, which are installed parallel to each other on the side of the second track plate 420 near the first track plate 410. There is a gap between the two linear tracks 422. The length of each linear track 422 extends parallel to one diagonal of the second track plate 420 and intersects (or is perpendicular to) the other diagonal of the second track plate 420. The two linear tracks 422 guide the arc-shaped track component 41 to move in a straight line. The drive component 421 is located between the two linear tracks 422 and drives the linear tracks 422 to run. Since the positioning component 423 is fixedly connected to the top corner of the second track plate 420, the linear movement of the first track plate 410 will cause the positioning component 423 to move in an arc along the arc-shaped track 411. Simultaneously with the linear movement of the second track plate 420, the movement of the positioning component 423 along the arc-shaped track 411 causes the rotating top plate assembly 21 and the rotating bottom plate assembly 22 to rotate synchronously, thereby causing the rotating cabinet to rotate.

[0062] An arc-shaped rack 413 is positioned on the side of the arc-shaped track 411 away from the first track plate 410, with its tooth surface facing the guide shaft 4122, for meshing with the spur gear 4234. The bevel gear 4233 has its tooth surface facing the second track plate 420, for meshing with the gear teeth 426 of the drive rod 4212. The spur gear 4234 is coaxial with the bevel gear 4233, and the tooth direction of the spur gear 4234 intersects with that of the bevel gear 4233. The spur gear 4234 meshes with the arc-shaped rack 413 to convert rotational motion into arc-shaped motion.

[0063] The driving component 421 includes a motor 4211 and a driving rod 4212. The motor 4211 is connected to the driving rod 4212 and drives the driving rod 4212 to move. The driving rod 4212 transmits power and meshes with a bevel gear 4233 through gear teeth 426. The bevel gear 4233 transmits power to a coaxial spur gear 4234, which meshes with an arc-shaped rack 413, thereby driving the arc-shaped track component 41 to achieve linear and arc-shaped movements. The length extension direction of the driving rod 4212 is the same as the length extension direction of the linear track 422 to ensure the synchronization of linear movements.

[0064] The aforementioned motor 4211 can be a geared motor, such as a DC brushless circular geared motor, with the model number Z32BLDPN2420-405-32PN.

[0065] Combination Figure 4 and Figure 11The aforementioned slider bearing component 43 includes a slider bearing plate 431, a fixed bearing 432, and a linear track slider 433. The slider bearing plate 431 serves as the basic support structure. The fixed bearing 432 is located on the side of the slider bearing plate 431 away from the second track plate 420 and is used to connect with the guide shaft 4122 of the guide component 412 to achieve arc-shaped movement. The linear track slider 433 is located on the side of the slider bearing plate 431 closer to the second track plate 420 and is slidably connected to the linear track 422 to achieve linear movement. The motor 4211 drives the drive rod 4212, which in turn drives the linear track slider 433 to perform reciprocating linear motion on the linear track 422. The linear track slider 433 matches the linear track 422 and is slidably connected to it, causing the slider bearing plate 431 to move linearly along the linear track 422. The fixed bearing 432 has a bearing hole 4321 at its center that matches the guide shaft 4122. The bearing hole 4321 of the fixed bearing 4322 and the guide shaft 4122 are interference-fitted, allowing the slider bearing plate 431 to move in an arc along the arc track 411. The arc movement is driven by linear motion and is achieved through the cooperation between the fixed bearing 432 and the guide member 412. The linear motion and the arc movement are synchronized to achieve a composite motion trajectory. The aforementioned slider bearing plate 431 acts as a bridge connecting the linear track 422 and the arc track 411, realizing the synchronization of linear motion and arc movement.

[0066] The working principle of the rotating cabinet is as follows: When the motor 4211 is started, it drives the drive rod 4212 to rotate. The gear teeth 426 on the drive rod 4212 mesh with the bevel gear 4233, causing the bevel gear 4233 to rotate. The bevel gear 4233 connects with the spur gear 4234, causing the spur gear 4234 to rotate accordingly. The spur gear 4234 meshes with the arc-shaped rack 413, causing the arc-shaped track component 41 to move along the straight track 42. The straight track slider 433 is slidably connected to the straight track 42. The motor 4211 drives the arc-shaped rack 413 through the drive rod spur gear 4234. The arc-shaped track groove 4113 of the arc-shaped track 41 moves along an arc-shaped trajectory based on the gear shaft 4232. During the movement, the position of the gear shaft 4232 remains fixed. Therefore, during the movement of the arc-shaped trajectory, the distance between the arc-shaped track 411 and the fixed bearing 432 will change. During the distance change, the linear track slider 433 will be driven to perform reciprocating linear motion on the linear track 42. The guide 412 is connected to the fixed bearing 432, and the arc-shaped track component 41 on the first track plate 410 rotates around the guide 412. The slider bearing plate 431 connects the fixed bearing 432 and the linear track slider 433, ensuring that the linear track slider 433 slides smoothly on the linear track 42, while supporting the rotational movement of the arc-shaped track component 41. That is, the motor 4211 drives the drive rod 4212, which drives the bevel gear 4233, the spur gear 4234 and the arc-shaped rack 413 to realize the combination of linear motion and arc-shaped motion. The guide 412 and the fixed bearing 432 support the rotational motion, the linear track slider 433 realizes the linear motion, and the slider bearing plate 431 ensures smooth movement.

[0067] The aforementioned motor 4211 can be driven by manually pushing the rotating cabinet 2 to trigger a touch switch, thereby automatically starting the motor 4211. Specifically, a touch switch (not shown in the figure) is installed behind the housing of the motor 4211 or near its centerline to detect manual rotation signals; levers (not shown in the figure) are installed at both ends of the arc-shaped track 411, pressing a limit switch during rotation; a limit switch is also fixedly installed on the motor 4211, which limits the rotation range (stopping at the limit point of the arc-shaped track) by touching the levers (not shown in the figure) at both ends of the arc-shaped track 411. The circuit board receives signals from the touch switch and the limit switch to control the start and stop of the motor 4211. For example, when the rotating cabinet 2 is pushed, the touch switch fixed behind the housing of the motor 4211 or at its centerline is triggered, and the circuit board detects the signal and automatically starts the motor 4211; levers are installed at both ends of the arc-shaped track 411, pressing a limit switch when the track reaches its limit position directly cuts off the motor power or sends a signal to the circuit board to force a stop. The circuit prioritizes responding to the limit switch signal. If a limit state is detected after manual triggering, the motor 4211 is prevented from starting. The circuit board described above can be a DMC1000B, but other circuit boards can be used depending on the actual situation. This embodiment does not limit this.

[0068] Depending on the actual situation, the motor 4211 can also be driven by a remote control to drive the circuit board and the motor. This embodiment does not specifically limit this method.

[0069] It should be noted that: in the upper arc-shaped track mechanism 3, the first track plate 410 is fixedly connected to the rotating top plate assembly 21 on the side near the fixed top plate assembly 11, and the second track plate 420 is fixedly connected to the fixed top plate assembly 11 on the side near the rotating top plate assembly 21. In the lower arc-shaped track mechanism 4, the first track plate 410 is fixedly connected to the rotating bottom plate assembly 22 on the side near the fixed bottom plate assembly 12, and the second track plate 420 is fixedly connected to the fixed bottom plate assembly 12 on the side near the rotating bottom plate assembly 22.

[0070] Optionally, along the direction from the fixed top plate assembly 11 to the fixed bottom plate assembly 12, the orthographic projections of the drive component 421, the positioning component 423, and the linear track 422 do not overlap at all. By separating the projections of the drive component 421, the linear track 422, and the positioning component 423, it is not only possible to ensure that they do not interfere with each other during movement, but also to make more efficient use of space, making the overall structure more compact. It can also reduce vibration and errors during movement and improve the movement accuracy of the rotary cabinet. In addition, the drive component 421, the positioning component 423, and the linear track 422 are arranged in a concentrated manner and do not interfere with each other, which facilitates installation and maintenance.

[0071] Compared with the prior art, the rotating cabinet provided in this embodiment achieves at least the following beneficial effects:

[0072] First, in this embodiment, the direct fixed connection between the guide component 412 and the first track plate 410 not only enhances the rigidity of the overall structure, reduces swaying, improves the stability of the rotating cabinet, and reduces the risk of loosening or wear, thus extending its service life, but also allows for easy replacement of the guide component 412 when it is damaged, reducing costs and facilitating maintenance. Furthermore, it ensures the alignment accuracy between the first track plate 410 and the guide component 412, reducing errors and making the rotating cabinet operate more smoothly. In addition, it reduces installation steps, lowers installation difficulty, and saves time and labor costs.

[0073] Secondly, through the mutual coordination between the arc-shaped track component 41, the linear track component 42, and the slider bearing component 43, the synchronization of linear and arc-shaped motion in the upper arc-shaped track mechanism 3 and the lower arc-shaped track mechanism 4 is achieved. For example, the driving component 421 drives the linear track slider 433, which in turn drives the slider bearing plate 431 to move along the linear track 422; at the same time, the cooperation between the arc-shaped track 411 and the positioning component 423 achieves arc-shaped motion.

[0074] Third, through the cooperation of motor 4211, arc-shaped rack 413, bevel gear 4233, spur gear 4234, and drive rod 4212, a combination of linear and arc-shaped motion between the fixed cabinet 1 and the rotating cabinet 2 is achieved. For example, motor 4211 drives drive rod 4212, drive rod 4212 meshes with bevel gear 4233 through gear teeth 426, transmitting power to spur gear 4234. Spur gear 4234 meshes with arc-shaped rack 413, driving arc-shaped track component 41 to move along linear track 42. Linear track slider 433 is slidably connected to linear track 42. Arc-shaped track 41 moves along an arc-shaped trajectory based on gear shaft 4232. During the movement, because the position of gear shaft 4232 is fixed, During the movement along the arc-shaped trajectory, the distance between the arc-shaped track 411 and the fixed bearing 432 will change. During the distance change, the linear track slider 433 will be driven to perform reciprocating linear motion on the linear track 42. The guide 412 is connected to the fixed bearing 432. The arc-shaped track component 41 on the first track plate 410 rotates around the guide 412. The slider bearing plate 431 connects the fixed bearing 432 and the linear track slider 433, ensuring that the linear track slider 433 slides smoothly on the linear track 42, while supporting the rotational movement of the arc-shaped track component 41. The above structure does not require manual operation, improves the power transmission efficiency, motion accuracy and stability, and is suitable for scenarios that require complex motion trajectories and high-precision control.

[0075] Optionally, the hollow positioning post 4231 is cylindrical or polyhedral on the side near the second track plate 420, and cylindrical on the side away from the second track plate 420. This structure not only ensures a stable connection between the positioning component 423 and the second track plate 420, preventing loosening and thus avoiding wobbling of the rotating cabinet during movement, but also accommodates the gear bearings 4235 built into the bevel gear 4233 and spur gear 4234. The polyhedrons include regular polyhedra (such as regular tetrahedrons and regular octahedrons), prisms (such as regular hexagonal prisms), and pyramids (such as triangular pyramids). When the hollow positioning post 4231 adopts a polyhedral design, it facilitates effective fixation to the second track plate 420, further reducing wobbling of the rotating cabinet during movement. This embodiment uses a cylindrical shape as an example.

[0076] In one alternative embodiment, a track plate opening 4201 is provided on one side of the second track plate 420 corresponding to the motor 4211, and the track plate opening 4201 penetrates the second track plate 420 in the direction from the fixed top plate group 11 to the fixed bottom plate group 12.

[0077] Specifically, continue to refer to Figure 3 As shown, the aforementioned track plate opening 4201 is located on one side of the second track plate 420, corresponding to the position of the motor 4211. This track plate opening 4201 provides mounting space for the motor 4211, allowing it to be easily fixed to the second track plate 420 without requiring additional mounting space. The track plate opening 4201 facilitates the disassembly and maintenance of the motor 4211, reducing maintenance costs and time. Directly fixing the motor 4211 to the second track plate 420 through the track plate opening 4201 reduces vibration and noise during operation.

[0078] In one alternative embodiment, the arc track 411 includes an inner arc track 4111 and an outer arc track 4112. The inner arc track 4111 is close to the guide member 412. An arc track groove 4113 is formed between the inner arc track 4111 and the outer arc track 4112. The positioning member 423 moves in an arc along the length extension direction of the arc track groove 4113.

[0079] Specifically, continue to refer to Figure 8As shown, the inner arc track 4111 and the outer arc track 4112 are mirror-symmetrically arranged. The inner arc track 4111 is located near the guide member 412 and is used to guide the arc-shaped movement of the positioning member 423. The arc-shaped track groove 4113 is formed by the inner arc track 4111 and the outer arc track 4112 and is used to abut the positioning member 423 and guide its arc-shaped movement. The positioning member 423 moves in an arc along the length of the arc-shaped track groove 4113. The inner arc track 4111 and the outer arc track 4112 work together to ensure that the movement trajectory of the positioning member 423 is precise and controllable.

[0080] Using the above scheme, the inner arc track 4111 and the outer arc track 4112 not only jointly guide the movement of the positioning component 423, ensuring the accuracy of the movement trajectory, but also provide dual support for the positioning component 423, enhancing movement stability. Simultaneously, they reduce vibration and impact during movement, improving movement smoothness. Furthermore, they make the force on the positioning component 423 more even, reducing wear and extending its service life. The arc-shaped track groove 4113 limits the movement range of the positioning component 423, reducing deviations during movement.

[0081] Optionally, the arc-shaped rack 413 is located on the side of the outer arc track 4112 away from the first track plate 410.

[0082] Specifically, in combination Figure 6 and Figure 8 As shown, the aforementioned arc-shaped rack 413 is located on the outer arc track 4112, which not only makes the meshing of the spur gear 4234 smoother and reduces energy loss in the power transmission process, thereby optimizing power transmission and improving power transmission efficiency, but also makes the movement of the positioning member 423 more stable, reduces deviations in the movement process, and makes the structure more compact and saves space.

[0083] In one alternative embodiment, combined with Figure 2 , Figure 3 , Figure 4 , Figures 13-16 As shown, Figure 11 This utility model provides an assembly drawing of the linear track component and the slider bearing component in an upper arc track mechanism and a lower arc track mechanism. Figure 13 This is a structural schematic diagram of a fixed cabinet provided by this utility model; Figure 14 This is a structural schematic diagram of a rotating cabinet provided by this utility model; Figure 15 This is a schematic diagram of the rotating cabinet provided by this utility model in the open state. Figure 16This is a schematic diagram of the rotating cabinet provided by this utility model in the closed state; an upper receiving space (not marked in the figure) is formed between the fixed top plate group 11 and the rotating top plate group 21, and a lower receiving space (not marked in the figure) is formed between the fixed bottom plate group 12 and the rotating bottom plate group 22; the upper arc-shaped track mechanism 3 is placed in the upper receiving space; and the lower arc-shaped track mechanism 4 is placed in the lower receiving space.

[0084] Specifically, the upper accommodating space is located between the fixed top plate assembly 11 and the rotating top plate assembly 21, and is used to accommodate the upper arc-shaped track mechanism 3. The lower accommodating space is located between the fixed bottom plate assembly 12 and the rotating bottom plate assembly 22, and is used to accommodate the lower arc-shaped track mechanism 4. The upper arc-shaped track mechanism 3 is placed in the upper accommodating space to guide the rotating top plate assembly 21 to move along the arc-shaped track 411, realizing the rotation of the upper part. The lower arc-shaped track mechanism 4 is placed in the lower accommodating space to guide the rotating bottom plate assembly 22 to move along the arc-shaped track 411, realizing the rotation of the lower part. The upper arc-shaped track mechanism 3 and the lower arc-shaped track mechanism 4 work together to ensure the smooth and synchronous overall movement of the rotating cabinet 2.

[0085] By adopting the above scheme, by placing the upper arc track mechanism 3 and the lower arc track mechanism 4 in the upper and lower accommodating spaces respectively, not only can the rotation function of the rotating cabinet 2 be realized and the motion trajectory be accurately controlled, but the motion stability can also be improved, vibration and impact can be reduced, and the overall structure of the rotating cabinet can be made more compact. In addition, it is easier to maintain and reduces maintenance costs.

[0086] In one optional embodiment, the fixed top plate assembly 11 includes a fixed top plate 111 and a first fixed side plate 112 connected to the fixed top plate 111. The length extension direction of the fixed top plate 111 is perpendicular to the length extension direction of the first fixed side plate 112. The fixed top plate 111 is a rectangular plate, and the first fixed side plate 112 is an L-shaped plate. The fixed top plate 111 and the first fixed side plate 112 form an L-shaped three-dimensional structure.

[0087] The rotating top plate assembly 21 includes a rotating top plate 211 and a first rotating side plate 212 connected to the rotating top plate 211. The length extension direction of the rotating top plate 211 is perpendicular to the length extension direction of the first rotating side plate 212. The rotating top plate 211 is a rectangular plate, and the first rotating side plate 212 is an L-shaped plate. The rotating top plate 211 and the first rotating side plate 212 form an L-shaped three-dimensional structure.

[0088] The fixed base plate assembly 12 includes a fixed base plate 121 and a second fixed side plate 122 connected to the fixed base plate 121.

The fixed base plate 121 is a rectangular plate, the second fixed side plate 122 is an L-shaped plate, and the fixed top plate 111 and the second fixed side plate 122 form an L-shaped three-dimensional structure.

[0089] The rotating base plate assembly 22 includes a rotating base plate 221 and a second rotating side plate 222 connected to the rotating base plate 221.

The rotating base plate 221 is a rectangular plate, and the second rotating side plate 222 is an L-shaped plate. The rotating top plate 211 and the second rotating side plate 222 form an L-shaped three-dimensional structure.

[0090] The fixed top plate 111, the first fixed side plate 112, the rotating top plate 211 and the first rotating side plate 212 form an upper receiving space, and the fixed bottom plate 121, the second fixed side plate 122, the rotating bottom plate 221 and the second rotating side plate 222 form a lower receiving space.

[0091] Specifically, Figure 2 , Figure 3 , Figure 4 , Figures 13-16 As shown, the fixed top plate 111 is a rectangular plate with four right-angled sides, and the first fixed side plate 112 is an L-shaped plate composed of two mutually perpendicular sides forming a right angle. The length extension direction of the L-shaped plate is the extension direction of its two sides. The fixed top plate 111 is connected to the first fixed side plate 112, and the length extension direction of the fixed top plate 111 is perpendicular to the length extension direction of the first fixed side plate 112. For example, the first side of the fixed top plate 111 is perpendicularly connected to the first side of the first fixed side plate 112, and the second side of the fixed top plate 111 is perpendicularly connected to the second side of the first fixed side plate 112.

[0092] The rotating top plate 211 is a rectangular plate with four right-angled sides. The first rotating side plate 212 is an L-shaped plate, consisting of two mutually perpendicular sides forming a right angle. The length of the L-shaped plate extends in the directions of its two sides. The rotating top plate 211 is connected to the first rotating side plate 212, and the length of the rotating top plate 211 is perpendicular to the length of the first rotating side plate 212. For example, the first side of the rotating top plate 211 is perpendicularly connected to the first side of the first rotating side plate 212, and the second side of the rotating top plate 211 is perpendicularly connected to the second side of the first rotating side plate 212.

[0093] The fixed top plate 111, the first fixed side plate 112, the rotating top plate 211 and the first rotating side plate 212 together form an upper accommodating space.

[0094] The fixed base plate 121 is a rectangular plate with four right-angled sides. The second fixed side plate 122 is an L-shaped plate, consisting of two mutually perpendicular sides forming a right angle. The length of the L-shaped plate extends in the directions of its two sides. The fixed base plate 121 is connected to the second fixed side plate 122, and the length of the fixed base plate 121 is perpendicular to the length of the second fixed side plate 122. For example, the first side of the fixed base plate 121 is perpendicularly connected to the first side of the second fixed side plate 122, and the second side of the fixed base plate 121 is perpendicularly connected to the second side of the second fixed side plate 122.

[0095] The rotating base plate 221 is a rectangular plate with four right-angled sides. The second rotating side plate 222 is an L-shaped plate, consisting of two mutually perpendicular sides forming a right angle. The length of the L-shaped plate extends in the directions of its two sides. The rotating base plate 221 is connected to the second rotating side plate 222, and the length of the rotating base plate 221 is perpendicular to the length of the second rotating side plate 222.

[0096] The fixed base plate 121, the second fixed side plate 122, the rotating base plate 221, and the second rotating side plate 222 form a lower accommodating space.

[0097] The aforementioned structure not only provides excellent support and stability, ensuring that the fixed cabinet 1 and rotating cabinet 2 are not easily deformed or tilted during use, but also effectively utilizes the upper and lower storage spaces to accommodate the upper arc-shaped track mechanism 3 and the lower arc-shaped track mechanism 4. This maintains the overall aesthetics and functionality of the rotating cabinet while smoothly guiding the arc-shaped movement of the rotating parts, improving the ease of use and flexibility of the rotating cabinet. Furthermore, it enhances the overall strength and durability of the rotating cabinet, extending its service life.

[0098] The inventors discovered that, taking cabinets as an example, users require the cabinet doors in the corners to remain open during operation to facilitate the retrieval of items, and then close the doors after operation. However, doors that are open for extended periods cannot be stored away, and the limited indoor operating space makes it inconvenient to repeatedly open and close the doors.

[0099] In an optional embodiment, based on the above-mentioned problems, the fixed cabinet 1 in this embodiment further includes a third fixed side panel 13 and a fourth fixed side panel 14. The third fixed side panel 13 and the fourth fixed side panel 14 are rectangular structures, and the third fixed side panel 13 and the fourth fixed side panel 14 form a first L-shaped structure. The two side edges of the fixed top plate 111 and the fixed bottom plate 121 are respectively connected to the third fixed side panel 13 and the fourth fixed side panel 14. The right-angle vertex of the L-shaped plate in the third fixed side panel 13 and the right-angle vertex of the L-shaped plate in the fourth fixed side panel 14 are respectively opposite to the right-angle vertex of the first L-shaped structure.

[0100] The rotating cabinet 2 includes a third rotating side panel 23 and a fourth rotating side panel 14. The third rotating side panel 23 and the fourth rotating side panel 14 are rectangular structures. The third rotating side panel 23 and the fourth rotating side panel 14 form a second L-shaped structure. The two side edges of the rotating top panel 211 and the rotating bottom panel 221 are connected to the third rotating side panel 23 and the fourth rotating side panel 14, respectively. The right-angle vertex of the L-shaped plate in the third rotating side panel 23 and the right-angle vertex of the L-shaped plate in the fourth rotating side panel 14 are respectively opposite to the right-angle vertex of the second L-shaped structure.

[0101] A column 25 is connected between the rotating top plate 211 and the rotating bottom plate 221, and the column 25 is diagonally positioned opposite the top corner of the second L-shaped structure.

[0102] Specifically, the third fixed side panel 13 and the fourth fixed side panel 14 form a first L-shaped structure. For example, the third fixed side panel 13 and the fourth fixed side panel 14 intersect at right angles to form an L-shaped frame, providing primary support and stability to the fixed cabinet 1. The right-angle vertex of the L-shaped panel in the third fixed side panel 13 faces the opposite direction to the right-angle vertex of the first L-shaped structure, and the right-angle vertex of the L-shaped panel in the fourth fixed side panel 14 faces the opposite direction to the right-angle vertex of the first L-shaped structure, thereby enhancing the symmetry and stability of the fixed cabinet 1.

[0103] The third rotating side panel 23 and the fourth rotating side panel 14 form a second L-shaped structure. The third rotating side panel 23 and the fourth rotating side panel 14 intersect at right angles, forming an L-shaped frame that provides primary support and stability to the rotating cabinet 2. The right-angle vertices of the L-shaped panels in the third rotating side panel 23 and the fourth rotating side panel 14 face opposite directions to the right-angle vertices of the second L-shaped structure, thereby enhancing the symmetry and stability of the rotating cabinet 2.

[0104] The aforementioned column 25 is a column, and its basic shape can be a square column, triangular column, trapezoidal column, or cylindrical column, etc. The column 25 connects between the rotating top plate 211 and the rotating bottom plate 221, and plays a supporting and fixing role. The column 25 is located at the diagonal position of the second L-shaped structure, that is, on the diagonal line of the right angle vertex in the second L-shaped structure.

[0105] When the rotating cabinet 2 is opened, it moves outward (i.e., floats outward) along the upper arc-shaped track mechanism 3 and the lower arc-shaped track mechanism 4. Then, the rotating cabinet 2 continues to rotate 180 degrees along the arc-shaped track 411. During the rotation, the two adjacent third rotating side plates 23 and fourth rotating side plates 14 turn inward. The backs of the two adjacent third rotating side plates 23 and fourth rotating side plates 14 correspond to the third fixed side plate 13 and the fourth fixed side plate 14, respectively. When the rotating cabinet 2 is closed, it first rotates 180 degrees in the opposite direction. After the rotation, the rotating cabinet 2 moves inward along the arc-shaped track 411 and returns to its original position. The two adjacent third rotating side plates 23 and fourth rotating side plates 14 also return to the closed state.

[0106] The specific assembly steps in this embodiment are as follows:

[0107] Step 1: Provide the rotating cabinet 2, fixed top plate assembly 11, fixed bottom plate assembly 12, third fixed side plate 13, fourth fixed side plate 14, upper arc track mechanism 3 and lower arc track mechanism 4, arc track component 41, linear track component 42 and slider bearing component 43. First, assemble the linear track component 42 and slider bearing component 43 in the upper arc track mechanism 3 together, and assemble the linear track component 42 and slider bearing component 43 in the lower arc track mechanism 4 together.

[0108] Step 2: Fix the linear track component 42 of the assembled lower arc track mechanism 4 to the fixed base plate assembly 12, wherein the slider bearing component 43 is opposite to the fixed base plate 121 in the fixed base plate assembly 12; fix the arc track component 41 of the lower arc track mechanism 4 to the rotating base plate assembly 22 in the rotating cabinet 2;

[0109] Step 3: Fix the linear track component 42 of the assembled upper arc track mechanism 3 to the fixed top plate assembly 11, wherein the slider bearing component 43 is opposite to the fixed top plate 111 in the fixed top plate assembly 11; fix the arc track component 41 of the upper arc track mechanism 3 to the rotating top plate assembly 21 in the rotating cabinet 2;

[0110] Step 4: Insert the guide 412 of the upper arc track mechanism 3 and the lower arc track mechanism 4 into the slider bearing 43, and the positioning part 423 abuts against the arc track 411.

[0111] Step 5: The third fixed side plate 13 and the fourth fixed side plate 14 are respectively connected to the two side edges of the fixed top plate group 11 and the fixed bottom plate group 12.

[0112] It should be noted that steps two and three above can be interchanged, but other steps are irreversible.

[0113] By adopting the above solution, (1) when the rotating cabinet 2 is in the open state, the third rotating side panel 23 and the fourth rotating side panel 14 can be easily stored and hidden, eliminating the need to repeatedly open and close the existing door panels during indoor operation; (2) it not only provides good support and stability for the fixed cabinet 1 and / or the rotating cabinet 2, but also makes effective use of the internal space of the fixed cabinet 1 and the rotating cabinet 2, while enhancing the overall strength and durability of the cabinet. In addition, when the rotating cabinet 2 is closed, it can prevent dust from falling into the rotating cabinet 2.
