Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more specifically, to a water purifier. Background Technology

[0002] Water purifiers (water dispensers) are primarily positioned to provide consumers with safe and healthy drinking water. Their core function lies in using a complex multi-stage filtration system (such as a combination of PP cotton, activated carbon, RO reverse osmosis membrane, and UV sterilization) to efficiently remove bacteria, viruses, heavy metals, organic pollutants, residual chlorine, odors, and various minute impurities from the water, ultimately outputting purified water or mineral water that meets direct drinking standards, effectively ensuring the user's daily drinking water health.

[0003] Currently, there are water purifiers that are often installed in kitchen cabinets, known as built-in water purifiers. They can blend seamlessly with the exterior of the cabinets, making them very aesthetically pleasing and popular with consumers.

[0004] However, the water dispensing section of existing water purifiers is usually recessed, limiting the surface area for dispensing water. Therefore, for larger water containers, users need to hold the container to fill it, resulting in a poor user experience. Utility Model Content

[0005] Therefore, it is necessary to provide a water purifier that allows users to use larger water containers to store water, thus addressing the aforementioned issues.

[0006] A water purifier, comprising:

[0007] The main unit includes a water intake section and a water outlet located in the water intake section, the water intake section including a water receiving surface disposed opposite to the water outlet; and

[0008] A flipping assembly, the flipping assembly including a second panel and a drive member for moving the second panel relative to the main unit between a first position and a second position, the second panel and the water intake part being located on the same side of the main unit;

[0009] When the second panel is in the first position, the second panel and the water-receiving surface are not on the same horizontal plane. When the second panel is in the second position, the second panel and the water-receiving surface are on the same horizontal plane, so as to extend the water-receiving surface.

[0010] The aforementioned water purifier, by setting a second panel, has undergone a deep optimization design of the water tray area at the bottom or front of the device without changing the overall appearance of the water purifier. This significantly increases the depth and solves the problem that users cannot stably place or have difficulty filling large-diameter and large-sized containers such as large kettles, pots, and large water bottles, thus improving the convenience of use and applicable scenarios.

[0011] In one embodiment, the second panel in the first position and the second panel in the second position are perpendicular to each other, and the drive is used to drive the second panel to rotate relative to the host between the first position and the second position.

[0012] In one embodiment, the main unit has a receiving portion below the water intake portion, the receiving portion having at least the filter element of the water purifier, and when the second panel is in the first position, the second panel can cover the receiving portion.

[0013] In one embodiment, the driving component includes a drive motor and a transmission rod. The drive motor drives the transmission rod to move. The transmission rod is tractively connected between the driving component and the second panel. The transmission rod can drive the second panel to rotate between a first position and a second position under the drive of the drive motor.

[0014] In one embodiment, the drive unit further includes a gear set, a track, and a traction rope. The gear set is driven between the drive motor and the traction rope. The traction rope is connected to the transmission rod. At least a portion of the transmission rod is disposed on the track. The gear set is capable of driving the traction rope to wind around, thereby driving at least a portion of the transmission rod to move along the track and extend or retract relative to the track.

[0015] In one embodiment, the flipping assembly further includes a limiting member located between the gear set and the drive rod, the traction rope being wound around the limiting member, the limiting member being used to ensure that the direction of the traction rope winding is opposite to the direction of the drive rod extending.

[0016] In one embodiment, the transmission rod includes a first rod and a second rod, both of which are rotatable relative to the main unit. The first rod is connected to the side of the second panel near the water intake part, and the second rod is disposed on the track and connected to the side of the second panel away from the water intake part. The limiting member is located between the second rod and the gear set.

[0017] In one embodiment, both the first rod and the second rod are arc-shaped, and the length of the second rod is greater than the length of the first rod.

[0018] In one embodiment, the gear set includes a first gear, a second gear, a third gear, a fourth gear, and a fifth gear. The first gear is coaxially arranged with the output shaft of the drive motor. The second gear meshes with the outside of the first gear, the third gear meshes with the outside of the second gear, the fourth gear and the third gear are coaxially arranged, and the inside of the fifth gear meshes with the outside of the fourth gear.

[0019] In one embodiment, the second rod includes a proximal end and a distal end, the proximal end being disposed on a track, the distal end being connected to a second panel, and the flipping assembly further includes an elastic member disposed between the extension of the track and the proximal end, wherein the elastic member is compressed when the second panel is in an open state.

[0020] In one embodiment, the water purifier further includes a first panel located outside the water intake section, and a second panel located on the same side of the main unit as the first panel; when the second panel is in a second position, the second panel and the first panel are in the same vertical plane.

[0035] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0036] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0037] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0040] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0041] Based on the design differences in filter replacement methods of current embedded water purifier products on the market, their internal structural layout can be mainly summarized as front panel with rear concealment and water inlet maintenance panel.

[0042] For the front-panel concealed structure, this design completely integrates the filter assembly (usually one or more filters) inside the cabinet, behind the front decorative panel of the water purifier unit. This means the filters are completely invisible from the outside. To enable filter replacement, the entire water purifier unit is typically mounted on a dedicated sliding rail system. When filter replacement is needed, the user or service personnel must open the cabinet door, unlock or release the sliding rail locking device, and then smoothly and completely pull the entire water purifier unit out of the cabinet along the rail. Only after the unit is fully exposed can the filter interface inside the unit be easily accessed to rotate, remove the old filter, and insert and lock the new filter. After replacement, the unit is pushed back into its original position in the cabinet along the rail and locked. This type of structure requires a certain depth of the cabinet interior, and the cabinet door must be opened with sufficient operating space to pull out the unit during replacement. The load-bearing capacity and durability of the sliding rail are also difficult to guarantee.

[0043] For water-receiving area service panel designs, the filter cartridge is directly placed in the lower space of the water purifier's water tray and faucet base area. For concealment and aesthetics, a removable independent panel is installed in this area. When the filter cartridge needs to be replaced, the user or service personnel do not need to move the entire main unit, but must first remove or open this dedicated service panel located below the water-receiving area, at which point the filter cartridge replacement can be performed directly. This type of structure has the following drawbacks: the presence of the service panel may slightly affect the overall appearance and is not aesthetically pleasing; space is limited, because due to the depth of the water-receiving area, the structural design can only shorten the length of the filter cartridge or increase the depth of the product, but the length of the filter cartridge will limit its water production performance, while the depth of the product will affect the installation environment (for example, the depth of kitchen cabinets can generally be 600mm, but the depth of wall cabinets or living room sideboards is generally only 350-450mm); replacement requires bending over or peering under the water-receiving area, and the removal of the service panel is cumbersome.

[0044] Meanwhile, neither of the two existing structures can solve the problem of water intake depth. The water intake is usually recessed, limiting the water intake surface. Generally, the more functions integrated, the more internal space is occupied, and the shallower the water intake becomes (for example, the ice water function requires a compressor and other condensation system). This means the water intake surface becomes narrower, and generally only small-diameter containers such as cups, small bowls, and thermos flasks can be used to collect water. Large-diameter containers such as pots and pans cannot be placed flat on the surface, requiring users to hold the container to collect water, resulting in a poor user experience.

[0045] See Figure 1-12 , Figure 1-5 A schematic diagram of a water purifier 1 according to an embodiment of this application is shown. The water purifier 1 provided in an embodiment of this application includes a main unit 10, a first panel 20, and a flip assembly 30. The water purifier 1 provided in an embodiment of this application is preferably an embedded water purifier 1.

[0046] The main unit 10 includes a water intake section 21 and a water outlet located on the water intake section 21. The water intake section 21 includes a water receiving surface disposed opposite to the water outlet. The flipping assembly 30 includes a second panel 100 and a drive member 200 for driving the second panel 100 to move relative to the main unit 10 between a first position and a second position. The second panel 100 and the water intake section 21 are located on the same side of the main unit 10.

[0047] The second panel 100 includes a first position and a second position. When the second panel 100 is in the first position, the second panel 100 and the water-receiving surface are not on the same horizontal plane. When the second panel 100 is in the second position, the second panel 100 and the water-receiving surface are on the same horizontal plane to extend the water-receiving surface.

[0048] Understandably, the second panel 100 includes a closed state and an open state, corresponding to the first position and the second position respectively. When the second panel 100 is in the closed state, the second panel 100 is separated from the water-collecting surface. When the second panel 100 is in the open state, the second panel 100 is in contact with the water-collecting surface, so that the second panel 100 and the water-collecting surface form a platform surface 101.

[0049] The aforementioned water purifier 1, by setting a second panel 100, has undergone a deep optimization design of the water tray area at the bottom or front of the device without changing the overall appearance of the water purifier 1. This significantly increases the depth and solves the problem that users cannot stably place or have difficulty filling large-diameter and large-sized containers such as large kettles, pots, and large water bottles, thus improving the convenience of use and applicable scenarios.

[0050] In one embodiment, the second panel 100 in the first position and the second panel 100 in the second position are perpendicular to each other, and the driving member 200 is used to drive the second panel 100 to rotate relative to the host 10 between the first position and the second position. Specifically, the second panel 100 in the first position is perpendicular to the water-collecting surface or forms a certain angle with it, and the second panel 100 in the second position is parallel to the water-collecting surface so that it is on the same horizontal plane.

[0051] In one embodiment, the water purifier 1 further includes a first panel 20, which is disposed outside the water dispensing part 21, and the second panel 100 is located on the same side of the main unit 10 as the first panel 20. When the second panel 100 is in a closed state, the second panel 100 and the first panel 20 are continuously arranged. The first panel 20 constitutes part of the exterior facade of the main unit 10. The first panel 20 has a through hole that avoids the water dispensing part 21, and the entire water dispensing part 21 is exposed through the through hole, with the water receiving surface located at the edge of the through hole. Specifically, when the second panel 100 is in a closed state, the second panel 100 and the first panel 20 are continuously arranged. "Continuously arranged" is defined as the second panel 100 and the first panel 20 forming the complete exterior facade of the water purifier 1 at this time, including but not limited to, the outer surfaces of the second panel 100 and the first panel 20 being located in the same plane, or the outer surfaces of the second panel 100 and the first panel 20 forming a visually continuous outer surface. When the second panel 100 is in the open state, it is in contact with the water-collecting surface. "In contact" means that the second panel 100 and the water-collecting surface can jointly fulfill the function of placing a container. The second panel 100 in the platform surface 101 acts as an extension, sharing the load-bearing function with the water-collecting surface. Contact includes, but is not limited to, situations where the outer surfaces of the second panel 100 and the water-collecting surface are located in the same plane, or where the outer surfaces of the second panel 100 and the water-collecting surface are spaced apart, or where there is no gap between them.

[0052] The first panel 20 constitutes the main control panel of the water purifier 1, integrating buttons and the like. The water intake section 21 has an inwardly recessed structure, with the water outlet located in the recessed area and on the upper wall of the recessed structure. Conversely, the water receiving surface is the lower wall of the recessed structure, which can be the upper surface of the water receiving box. The area between the upper and lower walls is the water receiving operation area.

[0053] Furthermore, the second panel 100 also includes an intermediate state between a closed state (first position) and an open state (second position). When the second panel 100 is in the intermediate state, the second panel 100 is inclined to the first panel 20. There are multiple intermediate states, each corresponding to a different angle between the second panel 100 and the first panel 20.

[0054] In one embodiment, the main unit 10 is provided with a receiving portion 11, the receiving portion 11 is provided with at least the filter element of the water purifier 1, and when the second panel 100 is in the first position, the second panel 100 can cover the receiving portion 11.

[0055] Specifically, such as Figure 1As shown, the accommodating part 11 includes a first accommodating area and a second accommodating area. The first accommodating area can be a maintenance and disassembly area for the main unit 10 components. The first accommodating area is equipped with at least the filter element of the water purifier 1, so that when the second panel 100 is in the second position (and intermediate state), the filter element and other components can be directly removed. The second accommodating area can be a storage compartment, a pure water tank, an ice storage compartment, or an ice maker, etc. The storage and maintenance space facilitates the realization of a modular and compact filter element compartment structure, and may adopt new composite filter materials or filter element forms with stronger performance and better volume. The storage and maintenance space also facilitates user modification, improving the user experience.

[0056] By incorporating the movable structure of the accommodating section 11 and the second panel 100, a practical storage and maintenance space is integrated within the main unit 10, facilitating user modifications and improving the user experience. When the second panel is open, it allows for maintenance of the main unit and storage of items. Key components such as filter cartridges can be installed here, avoiding the complex operation of traditional built-in water purifiers that rely on sliding rails to pull out the main unit 10 or require disassembling the maintenance panel. It provides easy access to the filter cartridge interface located inside the main unit 10, enabling the rotation, removal of old filters, and insertion and locking of new filters. This allows for easy replacement of filters and other components without moving the entire machine or reaching deep into the cabinet. Users can replace filters themselves, greatly improving maintenance efficiency and user experience, and making the installation of maintenance components faster and more standardized. Furthermore, the storage and maintenance space facilitates a modular and compact filter cartridge compartment structure, and may utilize new composite filter materials or filter cartridge forms with stronger performance and better volume, without needing to shorten the length of the filter cartridge or change the depth of existing products. The storage and maintenance space also allows for user modifications, further enhancing the user experience.

[0057] In one embodiment, when the second panel 100 is in the second position, the outer surface of the second panel 100 is parallel to the water-collecting surface. Specifically, when the second panel 100 is in the first position, the outer surface of the second panel 100 is parallel to the outer surface of the first panel 20, and the water-collecting surface is perpendicular to the outer surface of the first panel 20, so the second panel 100 has a 90° change between the second position and the first position.

[0058] In other embodiments, when the second panel 100 is in the second position, the outer surface of the second panel 100 forms a certain angle with the water-receiving surface, and the angle may be less than 10°, so that when the second panel 100 is in the second position, the angle between the outer surface of the second panel 100 and the outer surface of the first panel 20 is slightly less than 90°.

[0059] In one embodiment, the second panel 100 is rotatably connected to the host 10, and / or the second panel 100 is rotatably connected to the first panel 20. Specifically, the switching between the first and second positions of the second panel 100 is achieved by rotation.

[0060] Figure 6-12 A schematic diagram of the structure of the second panel 100 and the driving member 200 in one embodiment of this application is shown. In one embodiment, the host 10 and / or the first panel 20 are provided with the driving member 200. The driving member 200 includes a drive motor 230 and a transmission rod 220. The drive motor 230 is used to drive the transmission rod 220 to move. The transmission rod 220 is tractively connected between the drive motor 230 and the second panel 100. The transmission rod 220 can drive the second panel 100 to move between a first position and a second position under the drive of the drive motor 230.

[0061] Specifically, the drive motor 230 can be one or more of an electric drive motor 230, a hydraulic drive motor 230, and a pneumatic drive motor 230. An electric drive motor 230 refers to a drive device that uses electricity to provide power, and can include an electric motor, an electric actuator, etc. A hydraulic drive motor 230 uses the force of liquid to transmit power and generate motion, and can be a hydraulic pump, a hydraulic cylinder, a hydraulic motor, etc. A pneumatic drive motor 230 uses the force of gas to transmit power and generate motion, and can be a pneumatic cylinder, a pneumatic motor, a pneumatic valve, etc. In this embodiment, the drive motor 230 is preferably an electric motor, and the drive motor 230 also has an output shaft. The transmission rod 220 is a rod-shaped transmission component. Preferably, the transmission rod 220 can be one or more of an arc-shaped rotating rod, a connecting rod group, and a telescopic rod. In this embodiment, the transmission rod 220 can be an arc-shaped rotating rod. The rotation of the arc-shaped rotating rod drives the second panel 100 to rotate, so as to move between the first position and the second position.

[0062] In one embodiment, the drive unit 200 further includes a gear set 240 and a track 260 with a traction rope 250. The gear set 240 is tractively connected between the drive motor 230 and the traction rope 250. The traction rope 250 is connected to the transmission rod 220. At least a portion of the transmission rod 220 is disposed on the track 260. The gear set 240 can drive the traction rope 250 to wind around, thereby driving at least a portion of the transmission rod 220 to move along the track 260 and extend or retract relative to the track 260.

[0063] Specifically, gear set 240 includes a first gear 241, a second gear 242, a third gear 243, a fourth gear 244, and a fifth gear 245. The first gear 241 is coaxially mounted with the output shaft of the drive motor 230. The second gear 242 meshes with the outer side of the first gear 241, the third gear 243 meshes with the outer side of the second gear 242, the fourth gear 244 is coaxial with the third gear 243, and the inner side of the fifth gear 245 meshes with the outer side of the fourth gear 244. Gear set 240 also includes rotating shafts located at the centers of the first gear 241, second gear 242, third gear 243, fourth gear 244, and fifth gear 245, respectively. Thus, when the output shaft of the drive motor 230 rotates clockwise, the first gear 241, third gear 243, and fifth gear 245 all rotate clockwise, while the second gear 242 and fourth gear 244 rotate counterclockwise. The calculation formulas for the transmission ratio and torque of gear set 240 are shown in Equations 1-6 below.

[0064]

[0065] In Equations 1-6, i a i b i c i d These are the transmission ratios of the first gear 241, the second gear 242, the third gear 243, the fourth gear 244, and the fifth gear 245, respectively; 总 d1, d2, d3, d4, and d5 are the pitch circle diameters of the first gear 241, the second gear 242, the third gear 243, the fourth gear 244, and the fifth gear 245, respectively; W3 and W4 are the angular velocities of the third gear 243 and the fourth gear 244, respectively (because the third gear 243 and the fourth gear 244 are coaxial, their velocities are the same); T1 and T5 are the torques of the first gear 241 and the fifth gear 245, respectively.

[0066] Furthermore, such as Figure 9 , 10 As shown, the first gear 241 and the fifth gear 245 rotate in the same direction, and the diameter of the first gear 241 is smaller than the diameter of the fifth gear 245. From the formula relating T1 and T5, it can be seen that the larger the diameter d1 of the first gear 241, the larger the torque T1 (i.e., the motor output); conversely, the larger the diameter d5 of the fifth gear 245, the smaller the torque T1 (i.e., the motor output). This embodiment uses a transmission structure where the smaller first gear 241 drives the larger fifth gear 245, greatly reducing the output torque required for the motor to drive the first gear 241.

[0067] In one embodiment, the drive member 200 further includes a limiting member 280 located between the gear set 240 and the transmission rod 220, the traction rope 250 being wound around the limiting member 280, the limiting member 280 being used to ensure that the direction of the winding of the traction rope 250 is opposite to the direction of the extension of the transmission rod 220.

[0068] Specifically, one end of the traction rope 250 is connected to the fifth gear 245, which serves as the outward power output gear of the gear set 240. The middle of the traction rope 250 is wound around the limiting member 280, and the other end of the traction rope 250 is connected to the proximal end of the transmission rod 220. The limiting member 280 is located near the outlet of the transmission rod 220 (near the second panel 100), so that both the end of the traction rope 250 connected to the fifth gear 245 and the end of the traction rope 250 connected to the transmission rod 220 are located on the side of the limiting member 280 away from the second panel 100, so that the winding direction of the traction rope 250 is... Figure 11 , 12 When rotating clockwise, the transmission rod 220 extends outwards when rotating counterclockwise. The limiting member 280 is a cylindrical structure protruding from the housing 210.

[0069] Furthermore, the traction rope 250 can be made of flexible or rigid material. When the traction rope 250 is made of flexible material, it can be made of materials such as rubber or cotton rope. When the traction rope 250 is made of rigid material, it can be made of materials such as metal wire.

[0070] In one embodiment, the transmission rod 220 includes a first rod body 221 and a second rod body 222, both of which are rotatable relative to the host 10. The first rod body 221 is connected to the side of the second panel 100 close to the first panel 20, and the second rod body 222 is connected to the side of the second panel 100 away from the first panel 20. The limiting member 280 is located between the second rod body 222 and the gear set 240.

[0071] Specifically, the length of the second rod 222 is greater than the length of the first rod 221, and the radius of rotation of the second rod 222 is also greater than the radius of rotation of the first rod 221. Both the first rod 221 and the second rod 222 are arc-shaped. The transmission rod 220 also includes a connecting piece 223 that connects the ends of the first rod 221 and the second rod 222 together, and the connecting piece 223 is disposed between the first rod 221, the second rod 222, and the second panel 100.

[0072] In one embodiment, the drive unit 200 further includes a housing and a track 260 disposed within the housing, the second rod 222 being disposed on the track 260, and the second rod 222 moving along the track 260 under the action of the drive motor 230 and extending or retracting relative to the housing.

[0073] Specifically, the housing 210 is rectangular in shape and has a narrow width in the width direction of the water purifier 1 (the left-right direction when facing the first panel 20 of the water purifier 1). The housing 210 includes a base 211 and a top cover 212 that are detachably connected to each other. The base 211 and the top cover 212 are interlocked, forming an accommodating space between them. Similarly, the gear set 240 can also be housed within a detachable housing, with the housing located within the accommodating space.

[0074] The housing 210 is located at the edge of the main unit 10, or the housing 210 is connected to the first panel 20. The drive motor 230, traction rope 250, transmission rod 220, gear set 240, and track 260 are all located within the accommodating space of the housing 210. In the height direction of the water purifier 1 (the vertical direction when facing the first panel 20 of the water purifier 1), the drive motor 230 is located above the gear set 240, the first gear 241 is located at the top of the gear set 240, the fifth gear 245 is located at the bottom of the gear set 240, and the limiting member 280 is located between the track 260 and the fifth gear 245. In the depth direction of the water purifier 1 (the front-back direction when facing the first panel 20 of the water purifier 1), the track 260 is located at the rearmost side of the gear set 240, the second panel 100 is located at the frontmost side, the limiting member 280 is located between the track 260 and the second panel 100, and the gear set 240 and the drive motor 230 are located between the first rod 221 and the track 260. Along the width of the water purifier 1, the drive motor 230, traction rope 250, transmission rod 220, gear set 240, and track 260 are all arranged side by side.

[0075] The track 260 is arc-shaped and has the same shape as the second rod 222. The track 260 has a groove-shaped or channel-shaped structure, so that the second rod 222 is accommodated within the track 260 and moves along the track 260 from back to front to extend out of the housing 210. The second rod 222 moves along the track 260 from front to back to retract into the housing 210. The end of the track 260 facing the second panel 100 has an extension opening 261, which can be located at the foremost edge of the housing 210.

[0076] In one embodiment, the second rod 222 includes a proximal end and a distal end, the proximal end being disposed on a track 260 and the distal end being connected to a second panel 100. The drive member 200 further includes an elastic member 270 disposed between an extension 261 of the track 260 and the proximal end, wherein the elastic member 270 is compressed when the second panel 100 is in a second position.

[0077] Specifically, the proximal end is defined as the end of the second rod 222 that is always located inside the track 260 (housing 210), and the distal end is defined as the end of the second rod 222 that can extend out of the track 260 (housing 210). One end of the elastic member 270 abuts or is fixed to the protrusion 261, and the other end abuts or is fixed to the proximal end of the second rod 222. When the second panel 100 is in the second position, that is, when the proximal end moves to the end of the track 260 facing the protrusion 261, the elastic member 270 is compressed. When the second panel 100 is in the first position, that is, when the proximal end moves to the innermost side of the track 260, the elastic member 270 is in the reset state.

[0078] Understandably, there are two drive units 200, which are respectively located on the left and right sides of the main unit 10 and connected to the left and right sides of the second panel 100 to drive the second panel 100 to move in a balanced manner.

[0079] The working principle of this application embodiment is briefly described below: During the process of switching from the second position to the first position, the drive motor 230 (motor) rotates counterclockwise. Under the action of the gear set 240, the fifth gear 245 rotates counterclockwise, releasing the traction rope 250 wrapped on the fifth gear 245. Under the restoring force of the elastic element 270, the second rod 222 is driven to move backward along the track 260. Due to the guiding effect of the track 260, the second rod 222 is restricted to make circular motion within the track 260. The first rod 221 rotates synchronously with the second rod 222 until the spring is completely restored to its initial state. The corresponding second rod 222 is completely retracted into the track 260, completing the downward flipping of the second panel 100. During the transition from the first position to the second position, the drive motor 230 rotates clockwise. Under the transmission of the gear set 240, the fifth gear 245 rotates clockwise, tightening the traction rope 250 and wrapping part of the traction rope 250 around the fifth gear 245. The traction rope 250 pulls one end of the second rod 222 to compress the spring, causing the second rod 222 to move forward. The second rod 222 and the first rod 221 move in concentric circles. The first rod 221 acts as a balancing flap. When the second rod 222 reaches the end of the track 260, the length of the second rod 222 extending out of the housing 210 reaches its maximum. At this time, the second panel 100 switches to the second position (for example, the second panel 100 is at a 90° angle to the first panel 20). Due to the traction action of the drive motor 230 and the traction rope 250, as long as the drive output is maintained, the second position of the second panel 100 can be maintained, and the corresponding load capacity can be provided to the panel according to the magnitude of the motor torque.

[0080] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0081] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
