Description
Technical Field
[0001] This invention relates to the field of refrigerator technology, and in particular to an automatic refrigerator drawer module that is easy to install and remove. Background Technology
[0002] With the development of AI technology, the refrigerator industry has also kept pace with the times and begun to develop and produce smart refrigerators. How to automatically open and close the storage drawers in a smart refrigerator is an important issue. There are various opening methods in existing technologies, but all of them have certain shortcomings.
[0003] For example, Chinese patent CN202021958000 discloses an automatic door opening and closing device and a refrigerator, which uses a motor at the rear of the drawer to drive a gear and rack to automatically open and close the storage drawer. However, this opening and closing method has the following problems: under heavy drawer loads, the gear and rack are prone to intersecting due to side wall deformation; the gear and rack are prone to wear, shortening their service life; in severe cases, it can cause tooth breakage; and the installation and maintenance costs are extremely high. Another example is Chinese patent CN202110282980, which discloses a linear motion mechanism, drawer assembly, and storage cabinet. It uses a motor to drive a linear mechanism (belt-driven multi-stage) to automatically open and close the storage drawer. However, this opening and closing method has the following problems: belt drives are prone to slippage under heavy loads; the power system idles and loses kinetic energy, increasing refrigerator energy consumption. A remedy is to increase the belt preload, but given the belt's elasticity, defects will still be exposed after repeated use; installation defects also remain. Summary of the Invention
[0004] The purpose of this invention is to provide an easy-to-install and disassemble automatic refrigerator drawer module. This easy-to-install and disassemble automatic refrigerator drawer module has a modular structure, which reduces installation and maintenance costs. Through the cooperation of the main power shaft wheel and the auxiliary power shaft wheel, it is not easy to slip and runs smoothly.
[0005] To achieve the above objectives, the technical solution of the present invention is as follows:
[0006] An easy-to-install and disassemble automatic refrigerator drawer module is installed in the refrigerator liner. The liner has grooves on both sides facing each other, with a boss at the outlet end of each groove. An air duct module is fixedly installed on the innermost side of each groove. The module includes a handle mechanism, a drawer body, a linkage mechanism, and a motor assembly. The drawer body has load handle rotation shaft holes on both sides of its outer front end, and linkage assembly rotation shaft holes on both sides of its outer rear end. The linkage mechanism includes a load handle, a long connecting rod, and a linkage component hinged sequentially. The load handle is hinged to the load handle rotation shaft hole, and the linkage component is hinged to the linkage assembly rotation shaft hole. A drive power wheel set and an auxiliary power wheel set are rotatably mounted on the linkage component. The drive power wheel set includes a D-shaped shaft, with a drive power shaft wheel fixed to each end of the D-shaped shaft. Two drive gears are also fixed to the D-shaped shaft. The auxiliary power wheel assembly includes an auxiliary power shaft, with an auxiliary power wheel fixed to one end and an auxiliary gear fixed to the other end. The auxiliary power wheel is rotatably mounted in the drawer groove. The drive gear meshes with the auxiliary wheel. The drive power wheel and the auxiliary power wheel slide along the drawer groove. When the load handle is in the first position, the drive power wheel slides against the upper wall of the drawer groove, and the auxiliary power wheel slides against the lower wall of the drawer groove. When the load handle is in the second position, the drive power wheel and the auxiliary power wheel are flush. The motor assembly includes a motor fixed to the rear end of the drawer body. When the load handle is in the first position, the motor is driven by the drive power wheel. The handle mechanism includes an elastic handle plate that fixes the load handle in the first position. A detachable transmission line is connected to the motor.
[0007] The handle mechanism further includes a handle fixing plate and a front panel fixed to the front end of the drawer body. The handle plate is rotatably mounted on both sides of the handle fixing plate. The handle plate is provided with a torsion spring and a limit protrusion. The load handle is provided with a limit groove. When the limit protrusion is engaged in the limit groove, the load handle is in the first position.
[0008] The front panel is also equipped with an anti-collision unit.
[0009] The drawer body has side panels fixed on both sides, the side panels cover the linkage mechanism, and the front end of the side panels has an arc-shaped groove corresponding to the load handle.
[0010] The drawer body has a rear cover fixed to its rear end, which covers the motor. The rear cover has a fastening interface seat, which is internally connected to the motor via a signal line and externally detachably connected to the transmission line.
[0011] The air duct module is rotatably mounted with a torsion shaft, and the transmission line is wound around the torsion shaft.
[0012] The torque shaft shown is covered with a spool cover, which is fixed to the air duct module.
[0013] The motor output shaft is fixed with a motor gear, and a reduction gear is also provided on the D-shaped shaft. When the load handle is in the first position, the reduction gear meshes with the motor gear.
[0014] Among them, the mounting positions of the main power shaft wheel, the main gear, the auxiliary power shaft wheel and the auxiliary gear are all equipped with ring-shaped acetal steel isolation washers.
[0015] After adopting the above technical solution, the beneficial effects of the present invention are:
[0016] 1. This invention sets the refrigerator drawers into a modular structure, so that during installation and maintenance, only the entire drawer needs to be removed for repair or replacement, thus reducing installation and maintenance costs.
[0017] 2. By transferring the load between the auxiliary power shaft and the main power shaft, it is ensured that there will be no slippage, uneven force distribution, or jamming during the movement.
[0018] 3. The torsion shaft contains a torsion spring, which keeps the signal transmission line in a neat state, ensuring that the transmission line will not get stuck or tangled during the operation of the drawer; the signal transmission line end is equipped with a snap fastener structure, which will not separate from the fastening interface seat without human intervention. When it is necessary to remove the drawer, simply snap the snap fastener structure, and the signal line will automatically separate from the drawer and automatically return to the spool with the help of the torsion shaft.
[0019] In summary, the present invention provides an easy-to-install and disassemble automatic refrigerator drawer module that solves the technical problems of high installation and maintenance costs and slippage during automatic opening and closing of refrigerator drawers in the prior art. By setting the refrigerator drawer into a modular structure, installation and maintenance only require the entire drawer to be removed for repair or replacement, thus reducing installation and maintenance costs. Through the force transfer between the auxiliary power shaft and the main power shaft, slippage, uneven force distribution, and jamming are prevented during operation. Attached Figure Description

[0038] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0039] The directions mentioned in this manual are based on the directions shown in the attached diagram and represent only relative positional relationships, not absolute positional relationships.
[0040] like Figure 1 and Figure 2As shown, an easy-to-install and disassemble automatic refrigerator drawer module is installed in the refrigerator inner liner 1. Multiple modules can be installed in one inner liner 1. The inner liner 1 has grooves 11 on both sides facing each other. A boss limiting 111 is provided at the outlet end of the groove 11. The groove 11 forms a basic track structure, and the boss limiting 111 ensures that the drawer assembly 3 automatically extends and stops at the desired position. An air duct module 2 is fixedly installed on the innermost side of the groove 11. The air duct module 2 meets the basic air supply and distribution requirements of the refrigerator. In addition to meeting the air supply and distribution requirements, the air duct module 2 also has a rotatably mounted torque shaft 21, on which a transmission line 22 is wound. The outer fixing cover of the torque shaft 21 is equipped with a spool cover 23. The spool cover 23 has a hole for the transmission line 22 to pass through. One end of the transmission line 22 is fixed to the torque shaft 21, and the other end passes through the spool cover 23 after being wound around the torque shaft 21. The spool cover 23 ensures the uniqueness of the exit position of the transmission line 22 and provides shielding protection for the transmission line 22. The torque shaft 21 contains a torque shaft torsion spring (not shown in the figure), so that the signal transmission line 22 is always in a neat state, ensuring that the transmission line 22 will not get stuck or tangled during the operation of the drawer. The end of the signal transmission line 22 is equipped with a snap fastener 221, which will not separate from the fastening interface seat 521 without human intervention. When it is necessary to remove the drawer, simply snap the snap fastener 221, and the transmission line 22 will automatically separate from the drawer and automatically return with the help of the torque shaft 21. To install the drawer, simply reverse the process.
[0041] like Figure 1 , Figure 4 and Figure 5 As shown, an easy-to-install and disassemble automatic refrigerator drawer module includes a handle mechanism 31, a drawer body 32, a linkage mechanism 33, and a motor assembly 34.
[0042] The interior of the drawer body 32 serves as necessary storage space and does not have a protruding structure. Load handle rotation shaft holes 321 are provided on both sides of the front exterior of the drawer body 32, and linkage assembly rotation shaft holes 322 are provided on both sides of the rear exterior of the drawer body 32. The linkage mechanism 33 includes a load handle 331, a long connecting rod 332, and a linkage component 333, which are hinged sequentially. A stud is nested within the rotating shaft hole 321 of the load handle 331, providing the rotation center of the load handle 331. The stud locks two degrees of freedom, leaving one degree of freedom to ensure the rotational freedom of the load handle 331. One end of the long connecting rod 332 is hinged to the load handle 331, with the hinge point located above the rotating shaft hole 321. The other end is hinged to the linkage member 333, which is hinged to the rotating shaft hole 322 of the connecting rod assembly. The rotating shaft hole 322 of the connecting rod assembly provides the rotation center of the linkage member 333. A ring-locked connecting rod bearing 334 is provided on the linkage member 333, and a nested structure for the ring-locked connecting rod bearing 334 is provided within the rotating shaft hole 322 of the connecting rod assembly. A screw is tightly fastened within the linkage member 333, thereby locking two degrees of freedom and leaving one degree of freedom to ensure rotational freedom. A drive power wheel set 41 and an auxiliary power wheel set 42 are rotatably mounted on the linkage member 333.
[0043] like Figure 8 As shown, the drive gear assembly 41 includes a D-shaped shaft 411, with a drive gear 412 fixed to each end of the D-shaped shaft 411. A set of drive gears 413 are fixed to each end of the D-shaped shaft 411, located inside the drive gears 412. A drive shaft bearing 414 is rotatably mounted on the D-shaped shaft 411 between the drive gears 413 and the drive gears 412. To ensure the long-term use of the D-shaped shaft 411, an annular acetal steel insulating washer is added between the drive gears 412, the drive shaft bearings 414, and the drive gears 413 to prevent lateral displacement of the components.
[0044] like Figure 7 As shown, the auxiliary power wheel assembly 42 includes an auxiliary power shaft 421. An auxiliary power shaft wheel 422 is fixedly mounted at one end of the auxiliary power shaft 421, and an auxiliary gear 423 is fixed at the other end. An auxiliary power shaft bearing 424 is rotatably mounted on the auxiliary power shaft 421 between the auxiliary gear 423 and the auxiliary power shaft wheel 422. To ensure the long-term use of the auxiliary power shaft 421, annular acetal steel insulating washers are added between the auxiliary power shaft wheel 422, the auxiliary power shaft bearing 424, and the auxiliary gear 423 to prevent lateral displacement of the components.
[0045] like Figure 4 and Figure 6As shown, the auxiliary drive shaft 421 is located at the rear of the drawer body 32 and spans across the drawer body 32. The main drive wheel set 41 and the auxiliary drive wheel set 42 are simultaneously rotatably mounted on the linkage 333 via the main-auxiliary shaft connecting fastener 35, and the drive gear 413 meshes with the auxiliary gear 423. The fastening position of the main-auxiliary shaft connecting fastener 35 is at the position of the main drive shaft bearing 414 and the auxiliary drive shaft bearing 424, thereby realizing the rotatable mounting of the main drive wheel set 41 and the auxiliary drive wheel set 42 on the linkage 333. Because one main drive wheel set 41 has two main drive shaft wheels 412, one drawer body 32 is equipped with two auxiliary drive wheel sets 42.
[0046] The motor assembly 34 includes a motor 341 fixed to the rear end of the drawer body 32. A motor gear 342 is fixed to the output shaft of the motor 341, and a acetal steel isolating washer is also installed on the motor gear 342. A reduction gear 343 is fixed to the middle of the D-shaped shaft 411. The motor gear 342 meshes with the reduction gear 343, thereby driving the drive power wheel assembly 41 through the motor 341. The motor 341 provides power, the reduction gear 343 increases the output torque, the motor gear 342 ensures the operation of the drawer module when meshing with the reduction gear 343, and the acetal steel isolating washer prevents the motor gear 342 from displacing along the shaft, ensuring stable output.
[0047] Working principle of linkage mechanism 33:
[0048] The linkage mechanism 33 mainly utilizes the motion principle of a four-bar linkage. The long connecting rod 332 serves as the movable long rod of the four-bar linkage mechanism, while the ring-locked connecting rod bearing 334 and the stud in the rotating shaft hole 321 of the load handle serve as the fixed long rod of the four-bar linkage. The load handle 331 serves as the main driving short rod of the four-bar linkage, driving the linkage 333 to rotate. Because the length of the load handle 331 itself is much greater than the length of its own driving short rod functional section, its rotation characteristics also have the characteristics of saving effort, which can easily realize the rotation of the linkage 333. This provides a guarantee for the interference fit of the main power shaft wheel 412 and the auxiliary power shaft wheel 422. At the same time, by adjusting the position of the main power wheel set 41 during rotation, the meshing relationship between the reduction gear 343 and the motor gear 342 is also adjusted. During the manual operation of the load handle 331, the meshing between the reduction gear 343 and the motor gear 342 fails, so the motor 341 cannot be driven. The linkage 333 itself also has structural characteristics, which locks the distance between the driving power gear set 41 and the auxiliary power gear set 42, so that the meshing line of the driving gear 413 and the auxiliary gear 423 is always in a stable state, ensuring the stability of gear operation.
[0049] like Figure 4As shown, the handle mechanism 31 includes a handle fixing plate 311 fixed to the front end of the drawer body 32. A front panel 314 is fixed to the handle fixing plate 311, and a handle is provided on the front panel 314 to facilitate pushing and pulling the drawer body 32. Handle plates 312 are rotatably mounted on both sides of the handle fixing plate 311. The rotation axis of the handle plates 312 is vertically set, and a torsion spring 313 is provided on the rotation axis of the handle plates 312. The torsion spring 313 keeps the handle plates 312 tightly against the handle fixing plate 311. An anti-collision unit (not shown in the figure) is also provided on the handle fixing plate 311, which can detect whether there is an obstacle in front of the drawer body 32.
[0050] The handle plate 312 is provided with a limit protrusion, and the load handle 331 is provided with a limit groove. When the limit protrusion is engaged in the limit groove, the load handle 331 is in the first position. The load handle 331 is vertically positioned, the drive shaft wheel 41 slides against the upper wall of the groove 11, and the auxiliary drive shaft wheel 42 slides against the lower wall of the groove 11. The reduction gear 343 meshes with the motor gear 342.
[0051] When the lever 312 is turned, the limiting protrusion comes out of the limiting groove. Under the action of gravity and the inner groove 11, the load handle 331 rotates inward to the innermost position. When the load handle 331 is in the second position, the active power shaft wheel 41 and the auxiliary power shaft wheel 42 are aligned; the reduction gear 343 and the motor gear 342 no longer mesh.
[0052] like Figure 1 and Figure 4 As shown, side panels 51 are fixed to both sides of the drawer body 32, covering the linkage mechanism 33. An arc-shaped groove 511 is formed at the front end of the side panel 51 corresponding to the load handle 331. A rear cover 52 is fixed to the rear end of the drawer body 32, covering the motor assembly 34. A fastening interface seat 521 is provided on the rear cover 52. The fastening interface seat 521 is internally connected to the motor assembly 34 via a signal line, and externally detachably connected to a transmission line 22. The rear cover 52 provides protection for the rear mechanical structure and simultaneously presses against the motor assembly 34, ensuring stable and reliable power output.
[0053] Analysis of three high-load operating states of an easy-to-install and disassemble automatic refrigerator drawer module:
[0054] 1. High load withdrawal state
[0055] like Figure 9 , Figure 10 and Figure 11As shown, this is the state in which the refrigerator drawer spends the longest time. In this state, the load handle 331 is engaged in the handle mechanism 31. When the load handle 331 is in the first position, the reduction gear 343 meshes with the motor gear 342; the transmission line 22 is shorter, and the torque shaft 21 gathers most of the transmission line 22; the main drive shaft wheel 41 slides against the upper wall of the inner groove 11, and the auxiliary drive shaft wheel 42 slides against the lower wall of the inner groove 11 (Note: Under high load conditions, the inner wall deforms, and the lower auxiliary drive shaft wheel 42 bears more of the weight. At this time, the main drive shaft wheel 41 is the auxiliary force wheel, and the auxiliary drive shaft wheel 42 is the main propulsion wheel). In this state, the entire system meets the conditions for stable operation.
[0056] 2. High load shutdown state
[0057] like Figure 12 , Figure 13 and Figure 14 As shown in the diagram, this state is the state after the refrigerator drawer is pushed out by motor 341 after receiving a voice prompt or touch control. During the process of moving from state one to this state, because the front support of the inner groove 11 moves backward relative to the drawer body 32, the center of gravity of the drawer body 32 gradually moves forward, and the drawer body 32 will gradually have a tendency to sink at the head. In this state, the auxiliary power shaft wheel 42 and the lower wall of the inner groove 11 gradually change from being in close contact to being in close contact, and the main power shaft wheel 41 and the upper wall of the inner groove 11 gradually change from being in close contact to being in close contact. During this process, because the auxiliary power... The force transfer between the axle wheel 42 and the main drive axle wheel 41 ensures that there will be no slippage, uneven force, or jamming during the movement, resulting in a stable push-out process. With the help of the torque shaft 21, the transmission line 22 is also pulled out stably, without bending, drooping, or other unstable states interfering with the operation of the drawer body 32. The anti-collision unit also starts working at this time. After detecting an obstacle in front of the drawer body 32, it will stop the power supply in time to avoid collision. The meshing state of the load handle 331, reduction gear 343, and motor gear 342 is the same as the previous state. The above is the state analysis of the drawer module push-out process. The push-back process is the same, except that the anti-collision unit is not activated at this time to avoid interfering with the return of the drawer body 32.
[0058] 3. Drawer module removed (can be loaded; correspondingly, the operator needs to bear the load weight).
[0059] like Figure 15 , Figure 16 and Figure 17As shown in the diagram, this state is the removal of the drawer module. In state two, pry open the latch plate 312 from both sides. Under the influence of the drawer body 32's own weight and the restriction of the inner groove 11, the auxiliary power shaft wheel 42 and the main power shaft wheel 41 are aligned, and the drawer descends by half a wheel diameter (at this time, the reduction gear 343 has disengaged from the motor gear 342. If a voice prompt or touch control is received at this time, the motor 34 will start working. Regardless of whether it is pushed out or retracted, the auxiliary power shaft wheel 42 and the main power shaft wheel 41 will not rotate). At this time, the drawer body 32 can be lifted and the drawer body 32 can be pulled out (at this time, the transmission line 22 is still connected). After the transmission line 22 is exposed, manually pop out the snap fastener structure 221. The entire drawer module is de-energized and removed. Under the action of the torque shaft, the transmission line 22 automatically retracts back to its original position, and the removal action is completed. The installation action is the reverse of the removal action.
[0060] This invention provides an easy-to-install and disassemble automatic refrigerator drawer module, which solves the technical problems of high installation and maintenance costs and slippage during automatic opening and closing of refrigerator drawers in the prior art. By setting the refrigerator drawer into a modular structure, installation and maintenance only require the entire drawer to be removed for repair or replacement, thus reducing installation and maintenance costs. Through the force transfer between the auxiliary power shaft and the main power shaft, it ensures that there will be no slippage, uneven force distribution, or jamming during movement.
[0061] This invention is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort are within the scope of protection of this invention.
