Technical Field

[0001] The present invention relates to the field of furniture technology, and more specifically, to research and application of an intelligent rotating cabinet. Specifically, the present invention may also be called a rotating cabinet. Background Art

[0002] Lockers are mainly used to facilitate people's use and store different items. For families or dormitories with small spaces, lockers can make full use of the space to accommodate more daily necessities, and can also decorate people's home environment very well. Among them, corner cabinets, as a category of lockers, are a kind of cabinets fixed in the corner of the wall. They can use the space at the corner of the room for storage, which can effectively increase the storage space of the room.

[0003] The prior art (application number: 202411774858.3, application date: 2024.12.05) discloses a rotating cabinet track guide rotating structure, including a movable plate 1', a fixed plate 2' with the same area as the movable plate 1', a rotating component 3' located between the movable plate 1' and the fixed plate 2' and assembled with the movable plate 1' and the fixed plate 2' respectively, the rotating component 3' includes two linear tracks fixedly installed in parallel on the fixed plate 2' and having grooves, a damper arranged on the inner side of the two linear tracks and fixedly installed with the fixed plate 2', and a rotating seat movably assembled with the movable plate 1' at the upper end and movably assembled with the linear tracks and the damper at the lower end, the rotating seat includes a rotating seat body, a fixed bearing embedded in the center of the rotating seat body, and a rotating seat body installed in cooperation with the fixed bearing and assembled with the movable plate 1'.

In the above scheme, the shaft head is directly installed on the fixed bearing and subsequently 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 cost of replacement parts.

[0004] Therefore, there is an urgent need to provide a rotary cabinet with good stability, no need for manual operation, not easy to loosen, easy to maintain and low cost, which is a technical problem that urgently needs to be solved in the field. Summary of the invention

[0005] In view of this, the present invention provides a rotating cabinet for solving the problems that the shaft head is directly installed on the fixed bearing in the prior art and then inserted into the shaft head mounting hole, and the rotating cabinet has poor stability when rotating, and is manually operated, easy to loosen, troublesome to maintain, and high cost of replacement parts.

[0006] The present invention provides a rotating cabinet, comprising a fixed cabinet body, a rotating cabinet body, an upper arc track mechanism and a lower arc track mechanism, wherein:

[0007] The fixed cabinet comprises a fixed top plate group and a fixed bottom plate group in parallel; the rotating cabinet is located inside the fixed cabinet, and comprises a rotating top plate group corresponding to the fixed top plate group and a rotating bottom plate group corresponding to the fixed bottom plate group; the upper arc track mechanism is connected between the fixed top plate group and the rotating top plate group, and the lower arc track mechanism is connected between the fixed bottom plate group and the rotating bottom plate group;

[0008] The upper arc track mechanism and the lower arc track mechanism both include an arc track component, a linear track component and a slider bearing component, wherein:

[0009] The arc track member includes a first track plate, an arc track and a guide member, wherein the arc track is connected to the first track plate at a side away from the rotating cabinet; the guide member includes a guide column and a guide shaft fixedly connected to the guide column, wherein the guide column is fixedly connected to the midpoint of the first track plate at a side away from the rotating cabinet, and the guide column is cylindrical or polyhedron at a side close to the first track plate;

[0010] The linear track member comprises a second track plate, a driving member, a linear track and a positioning member, the driving member and the linear track are respectively connected to a side of the second track plate close to the first track plate, the positioning member comprises a hollow positioning column, a gear shaft, a bevel gear and a spur gear, the hollow positioning column is fixedly connected to the vertex angle of the second track plate close to the first track plate, a gear shaft is sleeved inside the side of the hollow positioning column close to the first track plate, the spur gear is located on the side of the bevel gear away from the hollow positioning column, the bevel gear and the spur gear are welded together and rotatably connected to the gear shaft through a gear bearing, and the tooth surface of the bevel gear faces the second track plate; the number of the linear tracks is two, and the driving member is located between the two linear tracks;

[0011] The arc-shaped track is provided with an arc-shaped rack on the side away from the first track plate, and the tooth surface of the arc-shaped rack faces the guide shaft; the spur gear is meshed with the arc-shaped rack, and the gear shaft drives the spur gear to move along the arc track of the arc-shaped rack after rotation; the driving member includes a motor and a driving rod connected to the motor, and the driving rod is provided with gear teeth matching the bevel gear on the side away from the motor, and the bevel gear is meshed 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 close to 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 driving rod. The slider bearing plate is provided with the fixed bearing on the side away from the second track plate. The guide shaft is rotatably connected to the fixed bearing.

[0013] Compared with the prior art, the rotary cabinet provided by the present invention achieves at least the following beneficial effects:

[0014] First, the direct fixed connection between the guide member and the first track plate in the present invention not only enhances the rigidity of the overall structure, reduces shaking, improves the stability of the rotary cabinet, reduces the risk of loosening or wear, and prolongs the service life, but also when the guide member is damaged, only the guide member needs to be replaced, which reduces the cost and facilitates maintenance. At the same time, the alignment accuracy between the first track plate and the guide member is ensured, the error is reduced, and the rotary cabinet runs more smoothly; in addition, the installation steps can be reduced, the installation difficulty is reduced, and time and labor costs are saved;

[0015] Second, through the coordination between the arc track parts, the linear track parts and the slider bearing parts, the synchronization of linear motion and arc motion in the upper arc track mechanism and the lower arc track mechanism is achieved.

[0016] Third, through the cooperation of the motor, arc rack, bevel gear, spur gear and driving rod, the combination of linear motion and arc motion between the fixed cabinet and the rotating cabinet is realized. For example, the motor drives the driving rod, and the driving rod meshes with the bevel gear through the gear teeth to transmit power to the spur gear. The spur gear meshes with the arc rack to drive the arc track member to move along the linear track. The linear track slider is slidably connected to the linear track. The arc track moves in an arc trajectory based on the gear shaft. During the movement, the position of the gear shaft is fixed, so the distance between the arc track and the fixed bearing will change during the movement of the arc trajectory. During the distance change, the linear track slider will be driven to perform reciprocating linear motion on the linear track; the guide member is connected to the fixed bearing, and the arc track member on the first track plate rotates around the guide member. The slider bearing plate connects the fixed bearing and the linear track slider to ensure that the linear track slider slides smoothly on the linear track while supporting the rotational motion of the arc track member. The above structure does not require manual operation, improves the power transmission efficiency, motion accuracy and stability, and is suitable for scenes requiring complex motion trajectories and high-precision control.

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

[0045] An arc-shaped rack 413 is provided on the side of the arc-shaped track 411 away from the first track plate 410, and the tooth surface of the arc-shaped rack 413 faces the side of the guide column 4121; the spur gear 4234 is meshed with the arc-shaped rack 413, and the gear shaft 4232 rotates to drive the spur gear 4234 to move along the arc track of the arc-shaped rack 413; the driving member 421 includes a motor 4211 and a driving rod 4212 connected to the motor 4211, and the driving rod 4212 is provided with gear teeth 426 matching the bevel gear 4233 on the side away from the motor 4211, and the bevel gear 4233 is meshed with the gear teeth 426;

[0046] The slider bearing member 43 includes a slider bearing plate 431, a fixed bearing 432 and a linear track slider 433. A linear track slider 433 matching the linear track 422 is provided on the side of the slider bearing plate 431 close to the second track plate 420.

A fixed bearing 432 is provided on the side of the slider bearing plate 431 away from the second track plate 420, and the guide shaft 4122 is rotatably connected to the fixed bearing 432.

[0047] Specifically, the research and application of the intelligent rotating cabinet can be an electric-driven rotating cabinet or a rotating cabinet, which is a rotatable cabinet body used to optimize space utilization and improve the convenience of taking and placing items. The rotating cabinet has a rotation or rotation movement mode and is used in kitchens, laboratories, and offices to store tools, equipment, or documents.

[0048] Combination Figure 2 and Fig.13 As shown, the fixed cabinet 1 is a hollow rectangular parallelepiped structure with side openings, which includes a fixed top plate group 11 and a fixed bottom plate group 12. The fixed top plate group 11 and the fixed bottom plate group 12 are parallel to each other, and the fixed top plate group 11 and the fixed bottom plate group 12 can be L-shaped three-dimensional structures. The fixed cabinet 1 can be an outer cabinet and an immovable cabinet, that is, the outer cabinet cannot rotate, providing structural support and protection for the rotating cabinet 2. The fixed top plate group 11 and the fixed bottom plate group 12 serve as the static support structure of the rotating cabinet.

[0049] Combination Figure 2 and Fig.14 As shown, the rotating cabinet 2 matches the fixed cabinet 1, and the rotating cabinet 2 can also be a hollow rectangular parallelepiped structure with side openings, which is located inside the fixed cabinet 1. The rotating cabinet 2 includes a rotating top plate group 21 and a rotating bottom plate group 22. The rotating top plate group 21, the fixed top plate group 11, the fixed bottom plate group 12 and the rotating bottom plate group 22 are parallel to each other, the rotating top plate group 21 is close to one side of the fixed top plate group 11, and the rotating bottom plate group 22 is close to one side of the fixed bottom plate group 12. The rotating top plate group 21 and the rotating bottom plate group 22 can be L-shaped three-dimensional structures. The above-mentioned rotating cabinet 2 can be an inner cabinet, which rotates smoothly relative to the outer cabinet.

[0050] The upper arc track mechanism 3 is connected between the fixed top plate group 11 and the rotating top plate group 21, so that the rotating top plate group 21 moves in an arc shape, and the rotating top plate group 21 slides on the upper arc track mechanism 3 to achieve a 180-degree rotation direction (such as clockwise or counterclockwise); the lower arc track mechanism 4 is connected between the fixed bottom plate group 12 and the rotating bottom plate group 22, so that the rotating bottom plate group 22 moves in an arc shape, and the rotating bottom plate group 22 slides on the lower arc track mechanism 4 to achieve a 180-degree rotation direction (such as clockwise or counterclockwise). The upper arc track mechanism 3 and the lower arc track mechanism 4 work together to ensure that the rotating top plate group 21 and the rotating bottom plate group 22 move synchronously to maintain structural stability.

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

[0052] Combination Figure 2 , Figure 3 , Figure 5-Figure 8 As shown, the arc track member 41 includes a first track plate 410, an arc track 411 and a guide member 412. The overall shape of the first track plate 410 is rectangular, which serves as the basic supporting structure of the arc track member 41. The arc track 411 is fixedly connected to the first track plate 410 on the side close to the first track plate 410, and the arc 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 track 411 are respectively located at two diagonal positions of the first track plate 410, and the arc track 411 is arranged along the diagonal direction.

[0053] It should be noted that the head and tail ends of the arc track 411 are respectively the end points of the rotation in the 180-degree rotation direction, i.e., the limit points. Based on a 180-degree clockwise or counterclockwise rotation, the head and tail ends of the arc track 411 are symmetrical based on the arc track 411, and are both located at the diagonal position of the first track plate 410.

[0054] The midpoint of the first track plate 410 away from the rotating cabinet 2 is fixedly connected to the guide column 4121, and the guide column 4121 is located on the side of the first track plate 410 away from the rotating cabinet 2. The guide column 4121 can be a hollow guide column or a solid guide column; the side of the guide shaft 4122 close to the guide column 4121 is welded together with the side of the guide column 4121 close to the guide shaft. If the guide shaft 4122 is a cylinder, when the guide column is a hollow guide column, one end of the guide shaft 4122 is inserted into the hollow part of the guide column 4121, and the joint surface of its circumferential surface and the hollow part of the guide column 4121 is fixed by circumferential welding. The guide column is a cylinder or a polyhedron, and the polyhedron includes a regular polyhedron (such as a regular tetrahedron, a regular octahedron), a prism (such as a regular hexagonal prism) and a pyramid (such as a triangular pyramid). When the guide column 4121 adopts a polyhedron design, it is conducive to effectively fixing it to the first track plate 410, and more effectively reducing the shaking of the rotating cabinet during movement. This embodiment only takes a cylinder as an example.

[0055] The inventors in this field have verified and summarized their experience many times, and the prior art discloses a rotating cabinet track guide 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, there are problems such as poor stability, easy loosening, troublesome maintenance and high replacement cost.

[0056] In this embodiment, since the guide column 4121 of the guide member 412 is directly fixedly connected to the midpoint of the first track plate 410 away from the rotating cabinet body 2, the guide column 4121 of the guide member 412 is directly fixed to the midpoint of the first track plate 410, which ensures uniform force, reduces the shaking of the rotating cabinet during movement, improves the overall stability, and avoids loosening caused by frequent movement, thereby 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, it is only necessary to check or replace the guide member 412 and its connecting parts without disassembling other complex components, thereby reducing 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 motion trajectory of the arc track 411 and the motion trajectory of the guide member 412 do not interfere with each other. For example, the arc track 411 is used to realize rotational motion, while the guide member 412 realizes linear and arc motion, 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 motion trajectories are independent of each other, thereby realizing more complex motion functions. In addition, the above design can also make more reasonable use of space and avoid overly complex structures.

[0058] Combination Figure 2 , Figure 3 , Figure 4 , Fig. 9 , Fig.10 , Fig.11 and Fig.12 As shown, the linear track member 42 includes a second track plate 420, a driving member 421, a linear track 422 and a positioning member 423. The overall shape of the second track plate 420 matches the first track plate 410. For example, the overall shape of the second track plate 420 is also rectangular, that is, the shapes of the first track plate 410 and the second track plate 420 are both rectangular; the second track plate 420 serves as the basic supporting structure of the linear track member 42, and is used to install the driving member 421, the linear track 422 and the positioning member 423. The driving member 421 is used to control the movement of the linear track 422, and the driving member 421 is connected to the side of the second track plate 420 close to the first track plate 410; the linear track 422 is used to provide a linear motion trajectory so that the second track plate 420 can move along a straight line, and the linear track 422 is connected to the side of the second track plate 420 close to the first track plate 410.

[0059] The hollow positioning column 4231 is fixed at the top corner of the second track plate 420, and a gear shaft 4232 is installed inside the hollow positioning column 4231. The gear shaft 4232 serves as a rotation support shaft for the spur gear 4234 and the bevel gear 4233. The spur gear 4234 and the bevel gear 4233 are processed separately, and the two are combined into a whole by friction welding. The gear bearing 4235 is subsequently embedded, and the gear bearing 4235 is rotatably connected with the gear shaft 4232, such as the inner ring of the gear bearing 4235 is interference fit with the gear shaft 4232, and the outer ring of the gear bearing 4235 is clearance fit 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 gear shaft 4232 is abutted against the arc track 411 on the side away from the hollow positioning column 4231.

[0060] The driving member 421 can drive the gear 426 on the rod 4212 to mesh with the bevel gear 4233, drive the bevel gear 4233 to rotate, the bevel gear 4233 is connected to the spur gear 4234, the spur gear 4234 rotates accordingly, and the spur gear 4234 meshes with the arc rack 413, drives the arc track member 41 to move along the linear track 42, so that the second track plate 420 can move along a straight line. The linear motion and the arc motion cooperate with each other, so that the second track plate 420 can achieve a complex motion trajectory. While the second track plate 420 is moving in a straight line, the gear shaft 4232 in the positioning member 423 moves along the arc track 411, so that the second track plate 420 produces an arc motion. The driving member 421, the linear track 422 and the positioning member 423 are centrally arranged on the side of the second track plate 420 close to the first track plate 410, so that the structure is more compact and easy to install and maintain.

[0061] There are two linear rails 422, which are installed in parallel on one side of the second track plate 420 close to the first track plate 410, with a spacing between the two linear rails 422, and the length extension direction of the linear rails 422 is parallel to a diagonal line of the second track plate 420, and intersects with another diagonal line of the second track plate 420 (such as being perpendicular to another diagonal line of the second track plate 420), and the two linear rails 422 are used to guide the arc track member 41 to move in a straight line, and the driving member 421 is located between the two linear rails 422, and is used to drive the linear rails 422 to operate. Since the positioning member 423 is fixedly connected to the top corner of the second track plate 420, the linear movement of the first track plate 410 will drive the positioning member 423 to move in an arc along the arc track 411, and while the second track plate 420 is moving in a straight line, the positioning member 423 moves along the arc track 411 to make the rotating top plate group 21 and the rotating bottom plate group 22 rotate synchronously, thereby causing the rotating cabinet to rotate.

[0062] The arc-shaped rack 413 is arranged on the side of the arc-shaped track 411 away from the first track plate 410, and the tooth surface of the arc-shaped rack 413 faces the side of the guide shaft 4122, and is used to mesh with the spur gear 4234. The tooth surface of the bevel gear 4233 faces the side of the second track plate 420, and is used to mesh with the gear teeth 426 of the driving rod 4212. The spur gear 4234 is coaxial with the bevel gear 4233, and the tooth direction of the spur gear 4234 intersects with the tooth direction of the bevel gear 4233; the spur gear 4234 meshes with the arc-shaped rack 413, and is used to convert the rotational motion into the arc motion.

[0063] The driving member 421 includes a motor 4211 and a driving rod 4212. The motor 4211 is connected to the driving rod 4212. The motor 4211 is used to drive the driving rod 4212 to move. The driving rod 4212 is used to transmit power. The driving rod 4212 meshes with the bevel gear 4233 through the gear teeth 426 to transmit the power to the bevel gear 4233. The bevel gear 4233 transmits the power to the coaxial spur gear 4234, and the spur gear 4234 meshes with the arc rack 413, thereby driving the arc track member 41 to achieve linear and arc motion. The length extension direction of the driving rod 4212 is the same as the length extension direction of the linear track 422, ensuring the synchronization of the linear motion.

[0064] The motor 4211 can be a reduction motor, such as a brushless DC circular reduction motor, whose model is Z32BLDPN2420-405-32PN.

[0065] Combination Figure 4 and Fig.11The above-mentioned slider bearing member 43 includes a slider bearing plate 431, a fixed bearing 432 and a linear track slider 433, wherein the slider bearing plate 431 is a basic support structure, the fixed bearing 432 is arranged 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 member 412 to achieve arc motion; the linear track slider 433 is arranged on the side of the slider bearing plate 431 close to the second track plate 420, and is slidably connected with the linear track 422 to achieve linear motion. The motor 4211 drives the driving rod 4212, and then 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 the linear track slider 433 is slidably connected with the linear track 422, driving the slider bearing plate 431 to perform linear motion along the linear track 422. The center of the fixed bearing 432 has a bearing hole 4321 that matches the guide shaft 4122. The bearing hole 4321 of the fixed bearing 43 and the guide shaft 4122 are interference fit, so that the slider bearing plate 431 can make an arc motion along the arc track 411. The arc motion is driven by the linear motion and is realized by the cooperation between the fixed bearing 432 and the guide member 412. The linear motion and the arc motion are performed synchronously to realize a composite motion trajectory. The above-mentioned slider bearing plate 431 serves as a bridge connecting the linear track 422 and the arc track 411 to realize the synchronization of the linear motion and the arc motion.

[0066] The working principle of the rotary cabinet is as follows: start the motor 4211, the motor 4211 drives the driving rod 4212 to rotate, the gear teeth 426 on the driving rod 4212 mesh with the bevel gear 4233, driving the bevel gear 4233 to rotate, the bevel gear 4233 is connected with the spur gear 4234, the spur gear 4234 rotates accordingly, the spur gear 4234 meshes with the arc rack 413, driving the arc track member 41 to move along the linear track 42, the linear track slider 433 is slidably connected with the linear track 42, the motor 4211 drives the arc rack 413 through the driving rod spur gear 4234, the arc track groove 4113 of the arc track 41 moves in an arc track based on the gear shaft 4232, and the position of the gear shaft 4232 is fixed during the movement. Therefore, during the movement of the arc track, the distance between the arc track 411 and the fixed bearing 432 will change, and during the distance change process, the linear track slider 433 will be driven to perform reciprocating linear motion on the linear track 42; the guide member 412 is connected to the fixed bearing 432, and the arc track member 41 on the first track plate 410 rotates around the guide member 412. The slider bearing plate 431 connects the fixed bearing 432 and the linear track slider 433 to ensure that the linear track slider 433 slides smoothly on the linear track 42 and supports the rotational motion of the arc track member 41; that is, the driving rod 4212 is driven by the motor 4211 to drive the bevel gear 4233, the spur gear 4234 and the arc rack 413 to achieve the combination of linear motion and arc motion. The guide member 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 the smooth motion.

[0067] The driving mode of the above-mentioned motor 4211 can be to manually push the rotating cabinet 2 to trigger the touch switch, thereby automatically starting the motor 4211 to drive. Specifically, a touch switch (not shown in the figure) is installed behind the shell of the motor 4211 or at the center line position near the motor 4211 to detect the manual rotation signal; a lever (not shown in the figure) is installed at both ends of the arc track 411 to press the travel switch when rotating; a travel switch is also fixedly installed on the motor 4211, and the rotation range is limited (the limit point of the arc track is stopped) by touching the lever (not shown in the figure) at both ends of the arc track 411. The circuit board is used to receive the signals of the touch switch and the travel switch to control the start and stop of the motor 4211. When the rotating cabinet 2 is gently pushed, the touch switch fixed at the rear of the shell of the motor 4211 or at the center line position is triggered, and the circuit board automatically starts the motor 4211 after detecting the signal; a lever is installed at both ends of the arc track 411, and the travel switch is pressed when rotating to the limit position, directly cutting off the power supply of the motor or sending a signal to the circuit board to force a stop. Priority is given to responding to the limit signal of the travel switch. If the limit state is detected after manual triggering, the motor 4211 is prohibited from starting. The model of the above circuit board can be DMC1000B. Of course, other models of circuit boards can also be selected according to actual conditions, and this embodiment does not limit this.

[0068] According to actual conditions, the motor 4211 may also be driven by a remote controller driving the circuit board and the motor, and this embodiment does not specifically limit this.

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

[0070] Optionally, along the direction from the fixed top plate group 11 to the fixed bottom plate group 12, the orthographic projection of the driving member 421, the orthographic projection of the positioning member 423 and the orthographic projection of the linear track 422 do not overlap at all. By separating the projections of the driving member 421, the linear track 422 and the positioning member 423, it can not only ensure that they do not interfere with each other during the movement, but also more efficiently utilize the space, making the overall structure more compact, and reducing vibration and errors during the movement, thereby improving the movement accuracy of the rotating cabinet. In addition, the driving member 421, the positioning member 423 and the linear track 422 are arranged centrally and do not interfere with each other, so as to facilitate installation and maintenance.

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

[0072] First, the direct fixed connection between the guide member 412 and the first track plate 410 in this embodiment not only enhances the rigidity of the overall structure, reduces shaking, improves the stability of the rotary cabinet, reduces the risk of loosening or wear, and prolongs the service life, but also when the guide member 412 is damaged, only the guide member 412 needs to be replaced, which reduces the cost and facilitates maintenance. At the same time, the alignment accuracy between the first track plate 410 and the guide member 412 is ensured, the error is reduced, and the rotary cabinet runs more smoothly; in addition, the installation steps can be reduced, the installation difficulty is reduced, and time and labor costs are saved;

[0073] Second, through the coordination between the arc track member 41, the linear track member 42 and the slider bearing member 43, the synchronization of the linear motion and the arc motion in the upper arc track mechanism 3 and the lower arc track mechanism 4 is achieved. For example, the driving member 421 drives the linear track slider 433, driving the slider bearing plate 431 to move along the linear track 422; at the same time, the arc track 411 cooperates with the positioning member 423 to achieve arc motion.

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

[0075] Optionally, the side of the hollow positioning column 4231 close to the second track plate 420 is a cylinder or a polyhedron, and the side of the hollow positioning column 4231 away from the second track plate 420 is a cylinder. The above structure can not only achieve a stable connection between the positioning member 423 and the second track plate 420, thereby avoiding looseness between the positioning member 423 and the second track plate 420, and thus avoiding the shaking of the rotating cabinet during movement, but also can adapt to the gear bearing 4235 built into the bevel gear 4233 and the spur gear 4234. The above polyhedron includes a regular polyhedron (such as a regular tetrahedron, a regular octahedron), a prism (such as a regular hexagonal prism) and a pyramid (such as a triangular pyramid). When the hollow positioning column 4231 adopts a polyhedron design, it is conducive to effectively fixing it to the second track plate 420, and more effectively reducing the shaking of the rotating cabinet during movement. This embodiment only takes a cylinder as an example.

[0076] In an optional embodiment, a track plate opening 4201 is opened 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 a direction from the fixed top plate assembly 11 to the fixed bottom plate assembly 12 .

[0077] Specifically, continue to refer to Figure 3 As shown, the track plate opening 4201 is provided on one side of the second track plate 420, corresponding to the position of the motor 4211. The track plate opening 4201 is used to provide an installation space for the motor 4211, so that the motor 4211 can be conveniently fixed on the second track plate 420, without providing an additional installation space for the motor 4211. The motor 4211 can be conveniently disassembled and maintained through the track plate opening 4201, reducing maintenance costs and time, and the motor 4211 is directly fixed to the second track plate 420 through the track plate opening 4201, which can reduce vibration and noise during movement.

[0078] In an optional 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, and the positioning member 423 makes an arc motion 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 arranged in mirror symmetry, the inner arc track 4111 is located near the guide member 412, and is used to guide the arc movement of the positioning member 423, and the arc 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 movement. The positioning member 423 moves in an arc along the length extension direction of the arc track groove 4113, and 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 accurately controllable.

[0080] By adopting the above scheme, the inner arc track 4111 and the outer arc track 4112 can not only jointly guide the movement of the positioning member 423 to ensure the accuracy of the movement trajectory, but also provide dual support for the positioning member 423 to enhance the movement stability, while reducing vibration and impact during the movement process, improving the movement stability, and in addition, it can also make the positioning member 423 more evenly stressed, reduce wear, and extend the service life. The arc track groove 4113 limits the movement range of the positioning member 423 and reduces the deviation during the movement process.

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

[0082] Specifically, combined Figure 6 and Figure 8 As shown, the arc-shaped rack 413 is located on the outer arc track 4112, which can not only make the spur gear 4234 mesh more smoothly and reduce the energy loss in the power transmission process, thereby optimizing the power transmission and improving the power transmission efficiency, but also make the movement of the positioning member 423 more stable and reduce the deviation in the movement process. At the same time, the structure is more compact and saves space.

[0083] In an alternative embodiment, in combination Figure 2 , Figure 3 , Figure 4 , Figure 13-Figure 16 As shown, Fig.11 It is an assembly diagram between a linear track component and a slider bearing component in an upper arc track mechanism and a lower arc track mechanism provided by the present invention; Fig.13 It is a structural schematic diagram of a fixed cabinet provided by the present invention; Fig.14 It is a structural schematic diagram of a rotating cabinet provided by the present invention; Fig.15 This is a schematic diagram of the use state of the rotary cabinet provided by the present invention in an open state; Fig.16It is a schematic diagram of the use state of the rotating cabinet provided by the present invention in a closed state; an upper accommodating space (not marked in the figure) is formed between the fixed top plate group 11 and the rotating top plate group 21, a lower accommodating space (not marked in the figure) is formed between the fixed bottom plate group 12 and the rotating bottom plate group 22, and the upper arc track mechanism 3 is placed in the upper accommodating space; the lower arc track mechanism 4 is placed in the lower accommodating space.

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

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

[0097] The above structure can not only provide good support and stability to ensure that the fixed cabinet 1 and the rotating cabinet 2 are not easily deformed or tilted during use, but also make the upper and lower accommodating spaces effectively utilized to place the upper arc track mechanism 3 and the lower arc track mechanism 4, while maintaining the overall beauty and functionality of the rotating cabinet, and can smoothly guide the arc movement of the rotating part, thereby improving the convenience and flexibility of the rotating cabinet. In addition, the overall strength and durability of the rotating cabinet can be enhanced, and the service life can be extended.

[0098] The inventors found that, taking a cabinet as an example, users require that the cabinet door panels at the corners be kept open during the operation time to facilitate taking items, and the door panels are not closed until the operation is completed. However, the door panels that are opened for a long time cannot be stored and hidden, and the indoor operating space is limited so that the door panels can only be opened and closed repeatedly, which is very inconvenient.

[0099] In an optional embodiment, based on the above problem, 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 respectively rectangular structures, and a first L-shaped structure is formed between the third fixed side panel 13 and the fourth fixed side panel 14, and two side edges of the fixed top panel 111 and the fixed bottom panel 121 are respectively connected to the third fixed side panel 13 and the fourth fixed side panel 14, and the right-angled vertex of the L-shaped panel in the third fixed side panel 13 and the right-angled vertex of the L-shaped panel in the fourth fixed side panel 14 are respectively opposite to the right-angled 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 respectively rectangular structures, and a second L-shaped structure is formed between the third rotating side panel 23 and the fourth rotating side panel 14, and two side edges of the rotating top panel 211 and the rotating bottom panel 221 are respectively connected to the third rotating side panel 23 and the fourth rotating side panel 14, and the right-angled vertices of the L-shaped panels in the third rotating side panel 23 and the right-angled vertices of the L-shaped panels in the fourth rotating side panel 14 are respectively opposite to the right-angled vertices of the second L-shaped structure;

The column 25 is located at a 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 along the upper arc track mechanism 3 and the lower arc track mechanism 4 (i.e., floats outward), and then the rotating cabinet 2 continues to rotate 180 degrees along the arc track 411, and the two adjacent third rotating side panels 23 and the fourth rotating side panels 14 turn to the inside during the rotation process, and the backs of the two adjacent third rotating side panels 23 and the fourth rotating side panels 14 respectively correspond to the third fixed side panels 13 and the fourth fixed side panels 14. When the rotating cabinet 2 is closed, the rotating cabinet 2 first rotates 180 degrees in the opposite direction, and after the rotation, the rotating cabinet 2 moves inward along the arc track 411 and returns to the original position, and the two adjacent third rotating side panels 23 and the fourth rotating side panels 14 are also reset to the closed state.
