Description

Technical Field

[0001] This application relates to the field of pull-down cabinets, and in particular to an electric pull-down cabinet. Background Technology

[0002] As society continues to develop, residents' quality of life is constantly improving; people's requirements for cabinet design are also constantly changing, among which pull-down cabinets have emerged.

[0003] Currently, among related technologies, Chinese patent with authorization announcement number CN206612424U discloses a pull-down spice basket hidden wall cabinet, including a cabinet door, wall cabinet body, hinges, long slide rail, slide track, buckle, short slide rail, drawer front, buffer block, side cabinet and retaining ring. By setting a slide track on the side cabinet of the wall cabinet, and then setting a drawer front, long slide rail and buckle inside the wall cabinet, it is convenient to use the buckle to drive the long slide rail to drop the drawer front from the slide track by gravity before cooking, making it convenient for people to take out the spice basket.

[0004] Further installation of short slide rails and corresponding tracks on both sides of the drawer front allows the drawer to be easily pulled out from the short slide rails when it lands on the countertop, making it convenient to access different seasonings while cooking. When cooking is finished, the drawer is slid back into the short slide rails, and then the long slide rails are pushed into the wall cabinet. The drawer front and side cabinet are then secured with clips. This design is not only convenient but also does not affect the aesthetics or tidiness of the kitchen.

[0005] However, if a glass bottle of condiments is placed on the drawer, it will have a certain impact force when it falls from the drawer due to gravity. Even if the buffer block acts as a buffer, the impact force cannot be completely offset. Moreover, the buffer block can recover its deformation instantly after being compressed, which means that it may rebound to a certain extent. As a result, the glass bottle of condiments on the drawer is extremely easy to tip over and roll off. Summary of the Invention

[0006] To address the problem that glass-bottled condiments are extremely prone to tipping over and rolling, this application provides an electrically operated pull-down cabinet.

[0007] This application provides an electrically operated pull-down cabinet, which adopts the following technical solution:

[0008] An electric pull-down cabinet includes: an outer shell and a lifting cabinet, wherein the lifting cabinet is disposed within the outer shell, and a lifting assembly is provided between the lifting cabinet and the outer shell;

[0009] The lifting assembly includes a slider, a lead screw, and a control motor. The inner sidewall of the outer casing has a groove. The slider is slidably connected in the groove and is fixedly connected to the lifting cabinet. The lead screw is rotatably installed in the groove and passes through the slider and is threadedly connected to the slider. The control motor is installed on the outer casing, and the output shaft of the control motor is coaxially fixed with the lead screw.

[0010] By adopting the above technical solution, the control motor is started to drive the lead screw to rotate in the forward direction; the rotation of the lead screw will drive the slider to move the lifting cabinet downward in the vertical direction, so that the lifting cabinet can extend out of the outer shell to retrieve items; and the lifting cabinet can descend slowly and stably, so that the items on the lifting cabinet are not easy to tip over, thereby enhancing the protection of the items.

[0011] Optionally, the lifting cabinet includes: a main board, two side panels and multiple partitions. The side panels are fixed to the main board, the partitions are fixed between the two side panels and are also fixed to the main board. A protective component is provided between two adjacent partitions, and a drive component is provided between the protective component and the outer shell.

[0012] By adopting the above technical solution, during the process of the lifting cabinet extending out of the outer shell, the drive component automatically operates to drive the protective component to slowly open the opening between the two adjacent partitions. During the opening process, the protective component can always play a blocking role; until the lifting cabinet is fully extended, the protective component fully opens the opening between the two adjacent partitions, thereby facilitating the retrieval of items.

[0013] Optionally, the protective component includes a protective part and a loosening part. The protective part includes a protective cloth, a first rope, and a second rope. The side wall of the partition has a first receiving hole and a second receiving hole from top to bottom. One end of the protective cloth is disposed in the first receiving hole and fixedly connected to the first rope, and the other end is disposed in the second receiving hole on the partition located above and fixed to the second rope. The first rope and the second rope are connected to the loosening part. The driving component is disposed between the loosening part and the outer shell.

[0014] By adopting the above technical solution, when the lifting cabinet extends out of the outer shell, the drive assembly will drive the unwinding part to wind up the first rope and release the second rope, so that the first rope will pull the protective cloth back to the first receiving hole, so as to slowly open the opening between the two adjacent partitions.

[0015] Optionally, the unwinding section includes: a first rod, a second rod, a first gear, and a second gear. The main board has an internal accommodating cavity. The first rod and the second rod are rotatably mounted in the accommodating cavity. The end of the first rope away from the protective cloth passes through the accommodating cavity and is fixedly connected to the first rod. The end of the second rope away from the protective cloth passes through the accommodating cavity and is wound around the second rod. The first gear is coaxially sleeved on the first rod, and the second gear is coaxially sleeved on the second rod, and the first gear and the second gear mesh. The driving assembly is disposed between the first rod and the outer casing.

[0016] By adopting the above technical solution, when the lifting cabinet extends out of the outer shell, the drive component will drive the first rod to rotate; the rotation of the first rod will drive the rotation of the first gear, the second gear and the second rod in sequence, and the rotation directions of the first rod and the second rod are opposite. The first rod will wind up the first rope and the second rod will release the second rope, so that the first rope will pull the protective cloth back towards the first receiving hole to slowly open the opening between the two adjacent partitions.

[0017] Optionally, the inner top wall of the outer casing is provided with a relief groove, and the sliding groove extends into the relief groove. The interior of the outer casing is provided with a receiving cavity, the control motor is installed in the receiving cavity, and the inner wall of the receiving cavity is fixedly provided with sound-absorbing cotton.

[0018] By adopting the above technical solution, sound-absorbing cotton can absorb the sound emitted by the control motor, thereby achieving the effect of noise reduction.

[0019] Optionally, the drive assembly includes a drive unit and a transmission unit. The drive unit includes a rack, a drive rod, and a drive gear. The inner sidewall of the housing has a receiving groove. The rack is fixedly installed in the receiving groove. The main board has a clearance hole communicating with the receiving cavity. The drive rod is rotatably installed in the receiving cavity. The drive gear is coaxially sleeved on the drive rod and meshes with the rack. The transmission unit is disposed between the drive rod and the first rod.

[0020] By adopting the above technical solution, during the process of the lifting cabinet extending out of the outer shell, the drive gear will rotate due to the meshing of the drive gear and rack. The rotation of the drive gear will drive the drive rod to rotate, and the rotation of the drive rod will drive the transmission part to drive the first rod to rotate.

[0021] Optionally, the transmission unit includes: a driving gear, a driven gear, a transmission rod, a transmission gear, and a rotating gear. The transmission rod is rotatably mounted in the accommodating cavity. The driving gear is coaxially sleeved on the driving rod. The driven gear is coaxially sleeved on the transmission rod, and the driving gear meshes with the driven gear. The transmission gear is coaxially sleeved on the transmission rod. The rotating gear is coaxially sleeved on the first rod, and the transmission gear meshes with the rotating gear.

[0022] By adopting the above technical solution, the rotation of the drive gear will sequentially drive the rotation of the drive rod, the driving gear, the driven gear, the transmission rod, the transmission gear, the rotating gear, the first rod, the first gear, the second gear, and the second rod. The rotation of the first rod will wind up the first rope, and the rotation of the second rod will release the second rope, so that the first rope will pull the protective cloth back towards the first receiving hole.

[0023] Optionally, a fixed cabinet is fixedly installed inside the outer shell, and a cabinet door is installed on the outer shell via a push assembly.

[0024] By adopting the above technical solution, the cabinet door can seal off the fixed cabinet body.

[0025] Optionally, the cabinet door consists of an upper door and a lower door, with the upper door hinged to the outer shell and the upper door hinged to the lower door. The pushing assembly includes a moving block and an electric push rod. The moving block is slidably disposed on the upper door, and the electric push rod is fixed in the outer shell, with the pushing shaft of the electric push rod hinged to the moving block.

[0026] By adopting the above technical solution, the electric push rod is activated to push the upper door to flip upwards to the side away from the fixed cabinet, and at the same time, the lower door moves, so that the fixed cabinet is no longer blocked, so that items can be taken out.

[0027] Optionally, the top of the first receiving hole at the opening and the bottom of the second receiving hole at the opening are configured as arc-shaped surfaces.

[0028] By adopting the above technical solution, when the protective cloth moves continuously within the first and second receiving holes, the arc-shaped surface can protect the protective cloth, making it less susceptible to damage due to scratches.

[0029] In summary, this application includes at least one of the following beneficial effects:

[0030] 1. The lifting cabinet can descend slowly and steadily, thus preventing items on the cabinet from tipping over and enhancing the protection of the items.

[0031] 2. When the lifting cabinet extends out of the outer shell, the drive assembly will drive the unwinding part to wind up the first rope and release the second rope, so that the first rope will pull the protective cloth back towards the first receiving hole, so as to slowly open the opening between the two adjacent partitions.

[0032] 3. As the protective cloth moves continuously within the first and second receiving holes, the arc-shaped surface can protect the protective cloth, making it less susceptible to damage from scratches. Attached Figure Description

[0040] This application provides an electric pull-down cabinet.

[0041] See Figure 1 , Figure 2 and Figure 3 An electric pull-down cabinet generally includes an outer shell 1 and a lifting cabinet 2. In practical applications, the outer shell 1 is fixedly installed on a table. In this embodiment, the bottom and one side of the outer shell 1 are provided as openings. The lifting cabinet 2 is disposed inside the outer shell 1 and can move up and down in the vertical direction, that is, it can extend and retract from the bottom of the outer shell 1.

[0042] See Figure 1 A lifting assembly 4 is provided between the lifting cabinet body 2 and the outer shell 1. The lifting assembly 4 includes a slider 41, a lead screw 42, and a control motor 43. The inner wall of the outer shell 1 on the side opposite to the side opening has a vertically oriented groove 11. The slider 41 is slidably connected to the sliding groove 11 and slides vertically. The slider 41 is fixedly connected to the lifting cabinet body 2. The lead screw 42 is rotatably installed in the sliding groove 11 and is vertically oriented. The lead screw 42 passes through the slider 41 and is threadedly connected to the slider 41.

[0043] See Figure 1 The control motor 43 is mounted on the outer casing 1, and the output shaft of the control motor 43 is coaxially fixed with the lead screw 42. To retrieve items from the lifting cabinet 2, the control motor 43 is started to drive the lead screw 42 to rotate in the forward direction. The rotation of the lead screw 42 will drive the slider 41 to move the lifting cabinet 2 vertically downward, so that the lifting cabinet 2 can extend out of the outer casing 1 to retrieve items. The lifting cabinet 2 can descend slowly and stably, so that the items on the lifting cabinet 2 are less likely to tip over, thus enhancing the protection of the items.

[0044] After the item is finished being used, the control motor 43 can be restarted to drive the lead screw 42 to rotate in the opposite direction, so that the lifting cabinet 2 can be retracted into the outer shell 1, thus eliminating the need for it to be exposed all the time and reducing the space occupied.

[0045] In this embodiment, a control switch is provided on the table, and the control switch is electrically connected to the controller (not shown in the figure). The control motor 43 is electrically connected to the controller so that pressing the control switch can control the control motor 43 to turn on and off, as well as to rotate in both directions.

[0046] See Figure 3 Furthermore, a clearance groove 12 is formed in the inner top wall of the outer casing 1, and the top end of the sliding groove 11 extends into the clearance groove 12. A receiving cavity 14 is provided inside the outer casing 1, and the receiving cavity 14 is located above the clearance groove 12. The control motor 43 is fixedly installed in the receiving cavity 14. Sound-absorbing cotton 141 is fixedly provided on the inner wall of the receiving cavity 14. The sound-absorbing cotton 141 can absorb the sound emitted by the control motor 43, thereby achieving a noise reduction effect.

[0047] See Figure 3 The lifting cabinet 2 includes a main board 21, two side panels 22, and multiple partitions 23. The two side panels 22 are fixed to the main board 21 and are perpendicular to the main board 21. The partitions 23 are fixed between the two side panels 22 and also to the main board 21. The partitions 23 are perpendicular to the side panels 22. The multiple partitions 23 are arranged at intervals along the height direction of the main board 21, and spaces are formed between adjacent partitions 23 to facilitate the placement of items.

[0048] See Figure 3 In addition, a fixed cabinet 3 is fixedly installed inside the outer shell 1. In this embodiment, the structure of the fixed cabinet 3 is the same as that of the lifting cabinet 2, but the size of the main board 21 is different. The fixed cabinet 3 is located on the side of the lifting cabinet 2 away from the slide groove 11. The outer shell 1 is provided with a cabinet door 15 on the side of the fixed cabinet 3 away from the lifting cabinet 2 through the push assembly 9. The cabinet door 15 can block the fixed cabinet 3.

[0049] See Figure 3 The cabinet door 15 consists of an upper door 151 and a lower door 152. The upper door 151 is hinged to the inner top wall of the outer casing 1, and the upper door 151 and the lower door 152 are also hinged. The pushing assembly 9 includes a moving block 91 and an electric push rod 92. The moving block 91 is slidably disposed on the side of the upper door 151 near the fixed cabinet 3 and can slide up and down. The electric push rod 92 is fixed to the inner top wall of the outer casing 1, and the pushing shaft of the electric push rod 92 is hinged to the moving block 91. When it is necessary to retrieve an item from the fixed cabinet 3, the electric push rod 92 is activated to push the upper door 151 to flip upwards away from the fixed cabinet 3, and simultaneously move the lower door 152, thereby removing the obstruction of the fixed cabinet 3 and allowing the item to be retrieved.

[0050] In this embodiment, the electric push rod 92 is also controlled by a control switch.

[0051] See Figure 4 , Figure 5 and Figure 6 A protective component is provided between two adjacent partitions 23. This component seals the opening between the two partitions 23, preventing items from falling off even if they tip over. A drive component is provided between the protective component and the outer shell 1. As the lifting cabinet 2 extends outward from the outer shell 1, the drive component automatically operates to slowly open the opening between the two adjacent partitions 23. During the opening process, the protective component maintains its sealing function. Once the lifting cabinet 2 is fully extended, the protective component completely opens the opening between the two adjacent partitions 23, facilitating the retrieval of items.

[0052] When the lifting cabinet 2 is stored inside the outer shell 1, the protective components can also prevent dust, thereby reducing the amount of dust entering between the two adjacent partitions 23, so that the items are less likely to be covered with dust.

[0053] See Figure 4 The protective components include: a protective section 5 and a loosening section 6.

[0054] See Figure 4 The protective part 5 includes: a protective cloth 51, a first rope 52 and a second rope 53. The partition 23 is located on the side away from the main board 21 and has a first receiving hole 231 and a second receiving hole 232 from top to bottom. One end of the protective cloth 51 is disposed in the first receiving hole 231 and fixedly connected to the first rope 52, and the other end is disposed in the second receiving hole 232 located on the adjacent partition 23 above and connected to the second rope 53. In this embodiment, there are two first ropes 52 and two ropes 53 corresponding to each end of the protective cloth 51, and they are located at both ends of the protective cloth 51 along the length direction.

[0055] See Figure 4 The unwinding section 6 includes a first rod 61, a second rod 62, a first gear 63, and a second gear 64. In this embodiment, each first receiving hole 231 corresponds to one first rod 61, and each second receiving hole 232 corresponds to one second rod 62. The main board 21 has an internal receiving cavity 211. The first rod 61 and the second rod 62 are rotatably mounted within the receiving cavity 211 and are horizontally positioned. One end of the first rope 52, away from the protective cloth 51, passes through the receiving cavity 211 and is fixedly connected to the first rod 61. One end of the second rope 53, away from the protective cloth 51, passes through the receiving cavity 211 and is wound around the second rod 62. The driving assembly is located between the first rod 61 and the outer casing 1.

[0056] See Figure 4 The first gear 63 is coaxially sleeved on the first rod 61, and the second gear 64 is coaxially sleeved on the second rod 62, with the first gear 63 and the second gear 64 meshing with each other. When the lifting cabinet 2 extends outward from the outer shell 1, the drive assembly will drive the first rod 61 to rotate; the rotation of the first rod 61 will sequentially drive the rotation of the first gear 63, the second gear 64, and the second rod 62, and the rotation directions of the first rod 61 and the second rod 62 are opposite. The first rod 61 will wind up the first rope 52, and the second rod 62 will release the second rope 53, so that the first rope 52 will pull the protective cloth 51 back towards the first receiving hole 231, so as to slowly open the opening between the two adjacent partitions 23;

[0057] When the lifting cabinet 2 is retracted into the outer shell 1, the first rod 61 will release the first rope 52, and the second rod 62 will wind up the second rope 53. Thus, the second rope 53 will pull the protective cloth 51 back into the second receiving hole 232, so as to slowly seal the opening between the two adjacent partitions 23.

[0058] See Figure 3 In this embodiment of the application, the second receiving hole 232 is not provided on the bottom partition 23 of the lifting cabinet 2, the first receiving hole 231 is not provided on the top partition 23, and the second rod 62 corresponding to the bottom partition 23 is not provided.

[0059] See Figure 4 Furthermore, the first receiving hole 231 located at the top of the opening and the second receiving hole 232 located at the bottom of the opening are both set as arc-shaped surfaces 233. When the protective cloth 51 moves continuously within the first receiving hole 231 and the second receiving hole 232, the arc-shaped surfaces 233 can protect the protective cloth 51 so that the protective cloth 51 is not easily damaged by scratches.

[0060] See Figure 4 , Figure 5 and Figure 6 The drive assembly includes a drive unit 7 and a transmission unit 8.

[0061] See Figure 5 The drive unit 7 includes a rack 71, a drive rod 72, and a drive gear 73. A receiving groove 13 is vertically formed on the inner side wall of the outer casing 1. The rack 71 is fixedly installed in the receiving groove 13 and is vertically arranged. A clearance hole 212 is formed on the side of the main board 21 near the receiving groove 13, and the clearance hole 212 communicates with the receiving cavity 211. The drive rod 72 is rotatably installed in the receiving cavity 211 and is horizontally arranged. The drive gear 73 is coaxially sleeved on the drive rod 72, and the drive gear 73 meshes with the rack 71.

[0062] See Figure 4 and Figure 6 The transmission unit 8 includes a driving gear 81, a driven gear 82, a transmission rod 83, a transmission gear 84, and a rotating gear 85. In this embodiment, the driving gear 81, driven gear 82, transmission gear 84, and rotating gear 85 are all bevel gears. The transmission rod 83 is rotatably mounted in the accommodating cavity 211 and is vertically arranged. The driving gear 81 is coaxially sleeved on the drive rod 72, and the driven gear 82 is coaxially sleeved on the transmission rod 83 and located at the top of the transmission rod 83. The driving gear 81 and the driven gear 82 mesh with each other.

[0063] See Figure 4 and Figure 6The transmission gear 84 is coaxially sleeved on the transmission rod 83, and the rotating gear 85 is coaxially sleeved on the first rod 61, with the transmission gear 84 and the rotating gear 85 meshing together. During the process of the lifting cabinet 2 extending outwards from the outer shell 1, the drive gear 73 will rotate. The rotation of the drive gear 73 will sequentially drive the rotation of the drive rod 72, the driving gear 81, the driven gear 82, the transmission rod 83, the transmission gear 84, the rotating gear 85, the first rod 61, the first gear 63, the second gear 64, and the second rod 62. The rotation of the first rod 61 will wind up the first rope 52, and the rotation of the second rod 62 will loosen the second rope 53. Thus, the first rope 52 will pull the protective cloth 51 back towards the first receiving hole 231, slowly opening the opening between the two adjacent partitions 23.

[0064] As the lifting cabinet 2 extends outward from the outer shell 1, the opposite occurs, thus the protective cloth 51 can seal the opening between two adjacent partitions 23.

[0065] The working principle of the electric pull-down cabinet of this application is as follows: During the process of the lifting cabinet body 2 extending outward to the outer shell 1, the drive gear 73 will rotate. The rotation of the drive gear 73 will sequentially drive the drive rod 72, the driving gear 81, the driven gear 82, the transmission rod 83, the transmission gear 84, the rotating gear 85, the first rod 61, the first gear 63, the second gear 64, and the second rod 62 to rotate. The rotation of the first rod 61 will wind up the first rope 52, and the rotation of the second rod 62 will release the second rope 53. Thus, the first rope 52 will pull the protective cloth 51 back towards the first receiving hole 231 to slowly open the opening between the two adjacent partitions 23.

[0066] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
