Description

Technical Field

[0001] The invention relates to cabinet technology, and in particular to a cabinet with variable space. Background Art

[0002] Cabinets are almost essential for kitchen furniture. They are used to hold kitchen utensils such as chopsticks and spoons, as well as tableware such as bowls and plates. Since chopsticks and spoons have significantly different shapes and sizes from bowls and plates, the automatic intelligent cabinets in the prior art are configured with different spaces for holding kitchen utensils such as chopsticks and spoons, and tableware such as bowls and plates, which are basically incompatible. Since automatic intelligent cabinets can realize functions such as automatic entry and exit, disinfection, and even automatic cleaning, they have developed rapidly in recent years and have gradually been applied on a large scale.

[0003] For example, the invention patent with the authorization announcement number CN104873006B and the authorization announcement date March 22, 2017, and the name "A fully automatic item storage smart cabinet", includes a cabinet body, a storage box and a control device, wherein the storage box is embedded in the cabinet body and is slidably connected to the cabinet body through a slide groove, the control device is embedded in the outer surface of the cabinet body and is electrically connected to the storage box, the storage box includes a box body, an item storage slot, a horizontal retrieval door and a vertical retrieval door, wherein the box body is embedded in the cabinet body, the horizontal retrieval door and the vertical retrieval door are both flush with the outer surface of the cabinet body, there is at least one item storage slot, which is embedded in the box body through a driving slide groove and is slidably connected to the box body, the driving slide groove includes a horizontal driving slide groove and a vertical driving slide groove, and the horizontal driving slide groove and the vertical driving slide groove correspond to the horizontal retrieval door and the vertical retrieval door respectively, and there is at least one horizontal driving slide groove and a vertical driving slide groove.

[0004] The shortcomings of the prior art are that the storage structure inside the cabinet is fixed in advance, that is, the dedicated space for holding kitchen utensils such as chopsticks and spoons and for holding tableware such as bowls and plates cannot be changed during use. However, the specific circumstances of each user are different during actual use, so it is impossible to adapt well. The cabinets on the market in the prior art also have a more direct solution, which is to additionally configure a carrying plate for holding kitchen utensils such as chopsticks and spoons, and the carrying plate needs to be directly inserted into the dedicated space for holding tableware such as bowls and plates. However, obviously, this wastes some space. Summary of the invention

[0041] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0042] like Figure 1-16 As shown, a cabinet with variable space provided by an embodiment of the present invention includes a cabinet body 1, in which a first carrying drawer 2 for carrying chopsticks and spoons and a second carrying drawer 3 for carrying bowls and plates are arranged, and a third carrying drawer 21 is also included, which has: a first mode, the third carrying drawer 21 is connected to a chopstick and spoon carrying portion, and the third carrying drawer 21 is connected to the first carrying drawer 2; a second mode, the third carrying drawer 21 is connected to a bowl and plate carrying portion, and the third carrying drawer 21 is connected to the second carrying drawer 3.

[0043] Specifically, a chopstick and spoon supporting structure for supporting chopsticks and spoons is provided in the first carrying drawer 2, and a bowl and plate supporting structure for supporting bowls and plates is provided in the second carrying drawer 3. The structures for supporting chopsticks and spoons as well as bowls and plates are different but are all prior arts and will not be described in detail. The key point of this embodiment is that it also includes a third carrying drawer 21, and the third carrying drawer 21 can be detachably connected to the chopsticks and spoon carrying part or the bowl and plate carrying part, that is, the third carrying drawer 21 is detachably configured with two carrying parts: the chopsticks and spoon carrying part or the bowl and plate carrying part, and it can be connected to any of the chopsticks and spoon carrying part or the bowl and plate carrying part. This choice makes the third carrying drawer 21 have two installation modes: the first mode and the second mode. In the first mode, the chopsticks and spoon carrying part is assembled on the third carrying drawer 21, and the third carrying drawer 21 is connected to the first carrying drawer 2, that is, at this time, the third carrying drawer 21 is connected to the first carrying drawer 2 as an integrated structure, and both are provided with a chopsticks and spoon carrying part for placing chopsticks and spoons. In the second mode, the bowl and plate carrying part is connected to the third carrying drawer 21, and the third carrying drawer 21 is connected to the second carrying drawer 3, that is, at this time, the third carrying drawer 21 is connected to the second carrying drawer 3 as an integrated structure, and both are provided with a bowl and plate carrying part for placing bowls and plates.

[0044] Preferably, the third carrying drawer 21 includes a rectangular or square cylindrical structure with openings at the top and bottom, and the chopsticks and spoon carrying part and the bowl and plate carrying part both include a bottom plate, and connecting structures such as a snap-on structure and a hanging structure (such as an inverted U-shaped hanging piece 22) are arranged on two opposite sides or four sides of the bottom plate to connect to the cylindrical structure, and a chopsticks and spoon carrying structure or a bowl and plate carrying structure is arranged on the bottom plate. Both types of structures are existing technologies and are not described in detail, so that the third carrying drawer 21 can be conveniently switched between the first mode and the second mode; in an optional embodiment, the third carrying drawer 21 includes a rectangular or square cylindrical structure with an opening at the top, so that the chopsticks and spoon carrying part and the bowl and plate carrying part both include a bottom plate, and a chopsticks and spoon carrying structure or a bowl and plate carrying structure is arranged on the bottom plate, and at this time the bottom plate can be directly overlapped with the bottom side plate of the cylindrical structure.

[0045] In addition, in this embodiment, the first drawer 2 and the second drawer 3 can be arranged side by side with a space for the third drawer 21 between them, that is, the three are arranged at the same height, or the first drawer 2, the second drawer 3 and the third drawer 21 are arranged in three layers. The connection between the third drawer 21 and the first drawer 2 and the second drawer 3, when arranged side by side and fitted, can be connected by a screw connection or an inverted U-shaped clamping structure to connect the third drawer 21 and the side plate of the first drawer 2 that fits. If arranged in two or three layers, a connecting bracket can be provided for plugging or hanging. Whether it is the connection between two drawer-like members in parallel or two drawer-like members in two layers, it is a prior art and will not be described in detail.

[0046] The space-variable cabinet provided in the embodiment of the present invention has a third carrying drawer 21 with two modes. Chopsticks, spoons and bowls and plates can be carried respectively in different modes. This makes the carrying space of chopsticks, spoons and bowls and plates inside the cabinet variable, which is convenient for adapting to different situations.

[0047] In another embodiment provided by the present invention, it further includes an automatic driving mechanism 4, and the automatic driving mechanism 4 is used to drive the first carrying drawer 2 and the second carrying drawer 3 to enter and exit the cabinet 1. Based on energy saving and humanization considerations, in most cases, the first carrying drawer 2 and the second carrying drawer 3 can be driven separately to enter and exit the cabinet 1, and two sets of automatic driving mechanisms 4 are respectively set accordingly. At this time, the automatic driving mechanism 4 includes a first driving component for driving the first carrying drawer 2 and a second driving component for driving the second carrying drawer 3. In a few cases, the first carrying drawer 2 and the second carrying drawer 3 enter and exit at the same time. At this time, a bracket connects the two, and the automatic driving mechanism 4 drives the two at the same time, which is not repeated.

[0048] In another embodiment provided by the present invention, when the first carrying drawer 2, the second carrying drawer 3 and the third carrying drawer 21 are arranged in three layers, the third carrying drawer 21 is arranged between the first carrying drawer 2 and the second carrying drawer 3; when in the first mode, that is, the chopstick and spoon carrying part is fixedly connected to the third carrying drawer 21, the third carrying drawer 21 is connected to the first extension part of the first carrying drawer 2 through the first connecting part 23 on the chopstick and spoon carrying part; when in the second mode, the bowl and plate carrying part is fixedly connected to the third carrying drawer 21, the third carrying drawer 21 is connected to the second extension part of the second carrying drawer 3 through the second connecting part on the bowl and plate carrying part; in this embodiment, since the first carrying drawer 2, the second carrying drawer 3 and the third carrying drawer The drawers 21 are arranged in three layers and the third drawer 21 is located in the middle, so the third drawer 21 must be provided with a first connecting portion 23 and a second connecting portion extending in the vertical direction, and the first connecting portion 23 and the second connecting portion extend one upward and one downward respectively. In the simplest way, the first connecting portion 23 and the second connecting portion are a rod. Obviously, optionally, the first connecting portion 23 and the second connecting portion can also be a plate or a bracket structure. The reason for arranging the first connecting portion 23 and the second connecting portion on the chopstick and spoon bearing portion and the bowl and plate bearing portion in this embodiment is that only the first connecting portion 23 is needed in the first mode, and only the second connecting portion is needed in the second mode, so as to prevent the coexistence of two connecting structures in different modes from occupying too much space. Correspondingly, the first extending portion and the second extending portion are structures connected to the first connecting portion 23 and the second connecting portion. In the simplest case, the first extending portion and the second extending portion are a through hole, and the rods of the first connecting portion 23 and the second connecting portion can be plugged in and connected, or other structures that can be connected to the plate or the bracket can be used. After the rods and the plate are plugged in, a limit pin is added to achieve the connection. These connection structures are all existing technologies and will not be elaborated on.

[0049] Preferably, the first extension part and the second extension part are multiple connecting tubes 24 arranged in parallel, that is, the first extension part is a plurality of connecting tubes 24 arranged on the first carrying drawer 2, and the second extension part is a plurality of connecting tubes 24 arranged on the second carrying drawer 3. More preferably, a protrusion is provided on the outer wall of the side panels of the first carrying drawer 2 and the second carrying drawer 3, and the protrusion is the connecting tube 24, that is, the connecting tube 24 can be integrated into the side panels of the first carrying drawer 2 and the second carrying drawer 3 to form an integrated structure, and the first connecting part 23 and the second connecting part are connected to different connecting tubes 24 at different positions of the width of the third carrying drawer 21, so that the first connecting part 23 and the second connecting part can be extended and inserted into the corresponding connecting tubes 24 to achieve connection, which is more convenient.

[0050] In each embodiment of the present invention, for the structure divided into multiple layers, it is obvious that those skilled in the art can understand that, in fact, there is no specific restriction on the upper and lower arrangement of the first carrying drawer 2, the second carrying drawer 3 and the third carrying drawer 21, and they can be arranged arbitrarily up and down, and based on their usage characteristics, for two carrying drawers connected together, such as the first carrying drawer 2 and the second carrying drawer 3, the two can be directly attached (the bottom of the first carrying drawer 2 is attached to the top of the second carrying drawer 3), at this time, the length of one of them can be larger and the other smaller, and there can also be a space between the two, which can be used for the operation of putting in and taking out tableware.

[0051] In another embodiment provided by the present invention, it also includes a trigger load-bearing structure, which includes a transmission mechanism and a clamping member arranged on a connecting tube 24; when the first connecting part 23 or the second connecting part is inserted into the connecting tube 24 to squeeze the transmission mechanism, the clamping member drives the clamping member to clamp the third load drawer 21. The transmission mechanism is a connecting rod mechanism or a wedge-shaped transmission mechanism, and its input end protrudes from the inner wall of the connecting tube 24. The first connecting part 23 is a structure that can be plugged into the connecting tube 24, such as a plug-in column. The plug-in column penetrates the third carrier 21 and the connecting tube 24 at the same time to achieve connection. The plug-in column is inserted into the connecting tube 24 to squeeze the input end of the transmission mechanism, and the output end of the transmission mechanism drives the clamping member, and the clamping member is driven to clamp the third carrier 21. The purpose of such a setting is that the third carrier 21 only relies on the first connecting part 23 or the second connecting part to achieve connection with the first carrier 2 and the second carrier 3. Especially in the second mode, the weight of the bowls and plates is relatively large, and relying solely on the second connecting part for connection may cause shaking, and may be deformed after long-term use, so an additional bearing structure is added.

[0052] In the simplest case, the transmission mechanism includes a horizontal block 25 and a vertical plate 26. One end of the horizontal block 25 is wedge-fitted with the top end of the vertical plate 26. The other end of the horizontal block 25 is also a wedge-shaped surface and is located in the connecting tube 24, while the other end of the vertical plate 26 is located at the edge of the first carrier drawer 2 or the second carrier drawer 3. In this way, when the plug-in column is inserted into the connecting tube 24, the horizontal block 25 is squeezed to force it to move axially. The axial movement of the horizontal block 25 drives the vertical plate 26 at the other end to move downward through the wedge-shaped fit. The vertical plate 26 moves downward and fits onto the outer surface of the third carrier drawer 21 to achieve clamping. The lower end of the vertical plate 26 is the clamping member.

[0053] In the embodiment of the above-mentioned horizontal block 25, the downward stroke of the vertical plate 26 is limited, which is more suitable for the case where the third carrier 21 is located at the top and the first carrier 2 and the second carrier 3 are located at the bottom. Therefore, in another optional embodiment, when the third carrier 21 is located at the bottom, it is more suitable that the transmission mechanism includes a first rod 27 and a second rod 28 that are abutted against each other, the first rod 27 is slidably connected to the connecting tube 24, and the second rod 28 is swingably connected to the connecting tube 24. The stroke of the plug-in column inserted into the connecting tube 24 drives the first rod 27 to move to drive the second rod 28 to swing to the position of clamping the third carrier 21. At this time, the first rod 27 is slidably connected to the top of the transmission tube, and the second rod 28 One end of the first rod 27 abuts against the top of the first rod 27, and the middle part of the first rod 27 is rotatably connected to the connecting tube 24 or the side plate of the first carrying drawer 2 or the second carrying drawer 3 next to the connecting tube 24 through the rotating shaft. The other end of the first rod 27 is located at the bottom of the side plate. When the plug-in column is inserted into the connecting tube 24, its top abuts against the bottom of the first rod 27 to drive the first rod 27 to move upward. The upward movement of the first rod 27 drives one end of the second rod 28 to swing upward, so that the second rod 28 swings around the rotating shaft as the center, so that the other end (i.e., the clamping member) swings downward to fit the edge of the third carrying drawer 21, that is, to achieve the fit of the third carrying drawer 21. The two sets of transmission mechanisms are both fitted to the two side plates of the third carrying drawer 21, that is, to achieve clamping and limiting. Moreover, since the second rod 28 is swinging, the position of the rotating shaft can be used to achieve a lever effect, and the swing amplitude can be large, thereby achieving a large range of limiting effects.

[0054] In another embodiment of the present invention, the automatic drive mechanism 4 includes a first transmission component, a second transmission component and a switching unit. The first transmission component is used to drive the first carrying drawer 2, and its power input end is a first gear 7; the second transmission component is used to drive the second carrying drawer 3, and its power input end is a second gear 8; the power input end of the switching unit is driven by the driving mechanism 4, and its power output end is driven to have two working positions: a first position driving the first transmission component and a second position driving the second transmission component. The first transmission component drives the first carrying drawer 2 to enter and exit the cabinet 1, and the second transmission component drives the second carrying drawer 3 to enter and exit the cabinet 1. Driving the carrying drawer to enter and exit the cabinet 1 is a prior art, such as the first transmission component and the second transmission component are cable components, which are pulled in and out of the cabinet 1 by the cable, or the first transmission component and the second transmission component are gear rack components, the rack is fixed on the first carrying drawer 2 or the second carrying drawer 3, the gear rack is meshed, and the gear rotates to drive the rack to drive the first carrying drawer 2 or the second carrying drawer 3 to enter and exit the cabinet 1. In this embodiment, the power input end of the first transmission component is the first gear 7, and the power input end of the second transmission component is the second gear 8. In this embodiment, only one driving mechanism 4 such as a motor is provided, and secondly, a switching unit is provided. The switching unit enables the driving mechanism 4 to drive the first transmission component and the second transmission component respectively. The power input end of the switching unit is driven by the driving mechanism 4. At this time, the output part of the driving mechanism 4 is the power output shaft. The switching unit includes a switching shaft 5. One end of the switching shaft 5 is slidably connected with the output shaft of the driving mechanism 4 through a non-rotating body such as a prism or an elliptical cylinder. For example, one end of the switching shaft 5 is a prism, and one end of the power output shaft is provided with a prismatic groove, and the prism is slidably connected in the prismatic groove. The effect brought about by this is that the rotation of the power output shaft can bring about the rotation axis of the switching shaft 5, but at the same time, the switching shaft 5 can move axially relative to the power output shaft, so that it has two working positions in the axial movement stroke: a first position for driving the first transmission component and a second position for driving the second transmission component. An output gear 6 is provided on the switching shaft 5. In the first position, the output gear 6 is meshed with the first gear 7, and in the second position, the output gear 6 is meshed with the second gear 8.

[0055] In the embodiment of the present invention, in the first position, the power transmission path is: the power output shaft of the driving mechanism 4, the switching shaft 5, the output gear 6, the first gear 7, the first transmission assembly and the first carrying drawer 2, and in the second position, the power transmission path is: the power output shaft of the driving mechanism 4, the switching shaft 5, the output gear 6, the second gear 8, the second transmission assembly and the second carrying drawer 3. The switching between the two positions only requires driving the switching shaft 5 to move axially, and the specific switching driving method is shown in the two embodiments below.

[0056] In the embodiment of the present invention, only one driving mechanism 4 is required, and the two carrying drawers (the third carrying drawer 21 is correspondingly connected to the first carrying drawer 2 or the second carrying drawer 3) are driven separately by switching the switching unit, thereby achieving the consideration of a single driving mechanism 4 and separate driving of two carrying bodies.

[0057] In another embodiment provided by the present invention, the first transmission assembly includes a first transmission shaft 10 provided with the first gear 7, a first pulley mechanism is provided on the first transmission shaft 10, and the first pulley mechanism drives the first carrying drawer 2. The second transmission assembly includes a second transmission shaft provided with the second gear 8, a second pulley mechanism is provided on the second transmission shaft, and the second pulley mechanism drives the second carrying drawer 3. In this embodiment, the pulley mechanism is used to drive the first carrying drawer 2 and the second carrying drawer 3 to perform linear reciprocating motion, such as the first pulley mechanism includes a driving pulley 9, the driving pulley 9 and the first gear 7 are located on opposite sides of the first transmission shaft 10, so that the rotation of the first gear 7 drives the rotation of the driving pulley 9, and a belt 12 is sleeved between the driving pulley 9 and the driven pulley 11, thereby driving the belt 12 to work, and a connecting member 13 is provided on the side plate of the first carrying drawer 2, and the connecting member 13 is connected to the belt 12 of the first pulley mechanism, so that the operation of the pulley mechanism drives the first carrying drawer 2 to reciprocate.

[0058] In another embodiment provided by the present invention, further, the first pulley mechanism includes a driving pulley 9 and a passive pulley 11, a belt 12 is sleeved between the driving pulley 9 and the passive pulley 11, the driving pulley and the passive pulley are rotatably connected to the cabinet body 1, the first carrying drawer 2 is connected to the belt 12 by a connecting piece 13 on its side panel, the top and bottom of the belt 12 are both horizontal sections, the connecting piece 13 is connected to the horizontal section, and the entry and exit stroke of the first carrying drawer 2 only requires the horizontal section to move back and forth, the first pulley mechanism rotates back and forth, so that when the driving pulley 9 rotates, it drives the belt 12 to move, and the movement of the belt 12 drives the first carrying drawer 2 to move back and forth so as to enter and exit the cabinet body 1. In the present embodiment, there are two first pulley mechanisms, which are disposed on opposite sides of the first carrying drawer 2, so that the two active pulleys 9 can be connected to a first transmission shaft 10 for convenient synchronous drive. In the present embodiment, the belt 12 includes a toothed section, and a first toothed structure 14 is provided on the outer surface of the toothed section. The connecting member 13 includes a strip member, and a second toothed structure 15 is provided on the strip member. The connecting member 13 is overlapped on the first toothed structure 14 through the second toothed structure 15. At the same time, the bottom of the first carrying drawer 2 is slidably connected to the cabinet body 1 through the slide rail 16, that is, the belt 12 drives the first carrying drawer 2 to move, and the bearing of the first carrying drawer 2 depends on the slide rail 16 of the cabinet body 1. At the same time, a roller 17 is provided at one end of the first drawer 2 that is away from the opening of the cabinet 1 (for the first drawer 2 to enter and exit), and the roller 17 is connected to the outer side of the belt 12 in a rolling manner. This arrangement brings two functions. First, after long-term use, when the front side plate of the first drawer 2 cannot be aligned with the outer side of the cabinet 1, or when the position of the first drawer 2 needs to be actively adjusted in other situations, the handheld part on the front side plate of the first drawer 2 can be manually lifted. At this time, the first drawer 2 is overlapped on the belt 12 with the roller 17, and the first toothed structure 14 is separated from the second toothed structure 15. In this way, the front and rear position adjustment can be achieved by pulling the first drawer 2 forward and backward, which is very convenient. Second, the first drawer 2 is completely overlapped on the belt 12, and it is very convenient to install and disassemble.

[0059] In another embodiment of the present invention, when the first carrier drawer 2 and the third carrier drawer 21 are connected in two layers by means of the plug-in column and the connecting tube 24, and the clamping is realized to limit the position by triggering the carrier structure, the first carrier drawer 2 is located at the upper part, and is overlapped on the upper surface of the upper section of the belt 12 of the first pulley mechanism through the above-mentioned toothed structure. At the same time, the third carrier drawer 21 is located below the first carrier drawer 2 and is provided with an upward abutment wheel 18, which rolls and abuts against the lower surface of the lower section of the belt 12 of the first pulley mechanism. Here, the upper section and the lower section refer to that when the pulley is sleeved on the driving pulley 9 and the passive pulley, its appearance is consistent with the appearance of a 400-meter runway, which includes Two parallel horizontal sections, both ends of the two horizontal sections are connected by a semicircular section, the upper section here refers to the upper section of the two horizontal sections, and the lower section refers to the lower section of the two horizontal sections. This arrangement brings two effects. First, the first carrier 2 squeezes the belt 12 from the top, and the second carrier 3 abuts against the belt 12 from the bottom, which has a tensioning effect. Second, since the upper and lower sections of the belt 12 move in completely opposite directions, the belt 12 always applies opposite forces to the first carrier 2 and the second carrier 3 during the movement, which is conducive to maintaining the stability of the first carrier 2 and the second carrier 3, and reduces the shaking phenomenon caused by the plug-in connection gap.

[0060] Obviously, those skilled in the art understand that the second pulley mechanism can be completely the same as the first pulley mechanism, and the pulley mechanism is a prior art and will not be described in detail.

[0061] In another embodiment provided by the present invention, the switching unit also includes a solenoid valve, and a magnetic attraction component that cooperates with the solenoid valve is arranged on the switching shaft 5. The opening and closing of the solenoid valve controls the switching shaft 5 to switch between the first position and the second position. In this way, the opening and closing or different polarities of the solenoid valve cause the magnetic attraction component to have two different positions, and the two different positions are the first position and the second position.

[0062] In another embodiment provided by the present invention, the switching unit also includes a telescopic drive unit 19, and the telescopic drive unit 19 is such as a micro telescopic motor, a telescopic electric rod, a cylinder, a hydraulic cylinder, etc. The advantage of the telescopic drive unit 19 is that it has more stay positions relative to the solenoid valve. At this time, the telescopic drive unit 19 drives the switching shaft 5 to switch between the first position, the second position and the third position; in the third position, the two power output ends of the switching unit respectively drive the first transmission assembly and the second transmission assembly. For the third position, two output gears 6 are provided on the switching shaft 5. In the third position, the two output gears 6 are respectively meshed with the first gear 7 and the second gear 8.

[0063] In the above two embodiments, since the switching shaft 5 needs to rotate, and the telescopic drive unit 19, the solenoid valve, etc. are not fixed, two matching mechanisms can realize this function. One is to connect a driving part 20 to the end of the switching shaft 5 in rotation, such as a cylindrical hole is set on the end of the switching shaft 5 away from the power output shaft, and an abutting shaft is rotatably sleeved in the cylindrical hole, and a radial ring is set on the abutting shaft, and a radial groove is set in the cylindrical hole. The radial ring cooperates with the radial groove, so that the axial movement of the abutting shaft can drive the axial movement of the switching shaft 5, and the switching shaft 5 rotates while the abutting shaft does not rotate, and the axial movement of the abutting shaft can realize the switching between the first position, the second position and the third position. Second, a radial protrusion is set on the switching shaft 5, and the end of the telescopic drive unit 19 is connected to the radial protrusion by a rolling element such as a wheel, so that no matter how the radial protrusion rotates, the rolling element can roll to squeeze the radial protrusion. Correspondingly, the reset of the switching shaft 5 can be performed by a spring, and the spring reset is a prior art and will not be repeated.

[0064] In each embodiment of the present invention, the driving motor of the driving mechanism 4 requires relatively large power, especially the second carrying drawer 3 for carrying bowls and plates requires a relatively large weight, generally reaching more than 7kg, and some even reaching more than 15kg. Based on this, the driving motor needs to be configured with relatively large power, while the telescopic driving unit 19 and the solenoid valve for driving the switching shaft 5 to move back and forth only need to drive one switching shaft 5, and their power is relatively small, and a micro motor (a motor with a diameter less than 160mm or a rated power less than 750W) can be used. Therefore, even if there are two driving units here, they are not on the same order of magnitude as the two driving units for driving the carrying drawers in the prior art, and the cost is still greatly reduced.

[0065] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
