In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0069] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0070] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on 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.

[0071] The terms “first,” “second,” and “third” (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0072] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0073] In existing technology, to improve the heating efficiency of induction cooktops, some cooktops feature a lifting support panel. This panel can rise and fall within the heating space. A first heating module is located below the support panel, and a second heating module is located on the side wall of the heating space. When the user places a pot on the support panel and the panel lowers, the first heating module heats the bottom of the pot, and the second heating module heats the sides. However, pots vary in size, and the fixed lifting range of the support panel is difficult to accommodate different pots. When the support panel lowers the pot, the second heating module may be too far from the side wall of the pot, affecting its heating effect. This makes it difficult for the induction cooktop to adapt to different sized pots, impacting the user experience.

[0074] In view of this, the inventors designed an induction cooker. A support panel supports the cookware, and a first heating module is fixedly installed below the support panel. A lifting component can raise and lower the support panel, and an adjustment component can move the second heating module laterally. A data acquisition module collects the dimensions of the cookware, and the descent stroke of the support panel and the lateral movement stroke of the second heating module are set according to the dimensions of the cookware. The induction cooker can adapt to cookware of different sizes, improving the user experience.

[0075] The technical solution of the induction cooker provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0076] Reference Figures 1 to 5As shown in the figure, the induction cooker provided in this application embodiment includes a fixed platform 100, a support panel 200, a lifting assembly 300, an adjusting assembly 400, a data acquisition module 500, and a controller. The fixed platform 100 has a receiving cavity 110. The support panel 200 is disposed in the receiving cavity 110, and a first heating module 210 is fixedly installed below the support panel 200. The support panel 200 is configured to support a cookware 800.

[0077] Schematic illustration: When the support panel 200 is in its highest position, its top surface is flush with the top surface of the fixed platform 100, allowing the user to place the pot 800 on it. The support panel 200 can be rectangular, circular, or other suitable shapes, without limitation. The support panel 200 and the first heating module 210 can be fixed together by fasteners or snap-fitting. The first heating module 210 may include an electromagnetic coil, which uses electromagnetic induction to heat the bottom of the pot 800.

[0078] The lifting assembly 300 is connected between the fixed platform 100 and the support panel 200, and the lifting assembly 300 is configured to drive the support panel 200 to rise and fall relative to the fixed platform 100.

[0079] When the user places the cookware 800 on the support panel 200, the lifting component 300 can lower the support panel 200, causing the bottom of the cookware 800 to embed into the receiving cavity 110. After cooking, the lifting component 300 can also raise the support panel 200 so that the user can remove the cookware 800 from the support panel 200. That is, the induction cooker provided in this embodiment is a built-in induction cooker.

[0080] An adjustment component 400 is disposed within the receiving cavity 110. The adjustment component 400 is connected to a second heating module 410. The adjustment component 400 is configured to drive the second heating module 410 to move laterally.

[0081] Specifically, the second heating module 410 is located inside the receiving cavity 110. When the cookware 800 is inserted into the receiving cavity 110, the adjusting component 400 can drive the second heating module 410 to move horizontally, so that the second heating module 410 is in contact with the side of the cookware 800. The second heating module 410 may include an electromagnetic coil, which heats the side of the cookware 800 by electromagnetic induction.

[0082] The acquisition module 500 is mounted on the fixed platform 100 and is configured to acquire the height and diameter of the pot 800.

[0083] A vision sensor can be used as the acquisition module 500, which can be installed on the top surface of the fixed platform 100. When the top surface of the support panel 200 is flush with the top surface of the fixed platform, and the pot 800 is placed on the support panel 200, the acquisition module 500 can acquire the height and diameter of the pot 800.

[0084] The controller is electrically connected to the lifting assembly 300, the adjusting assembly 400, and the data acquisition module 500. The controller is configured to control the lifting height of the support panel 200 based on the height of the cookware 800 acquired by the data acquisition module 500. The controller is also configured to control the adjusting assembly 400 to drive the second heating module 410 to fit against the side of the cookware 800 based on the diameter of the cookware 800 acquired by the data acquisition module 500.

[0085] Indicatively, the acquisition module 500 can transmit the height and diameter information of the cookware 800 to the controller. Based on the height information, the controller controls the lifting component 300 to lower the support panel 200, matching the height of the support panel 200. Based on the diameter information, the controller controls the adjusting component 400 to move the second heating module 410 laterally, ensuring the second heating module 410 fits against the side of the cookware 800. In other words, the controller can control the movement of the support panel 200 and the second heating module 410 based on the height and diameter of the cookware 800, allowing the induction cooker to accommodate cookware 800 of different sizes.

[0086] The induction cooker provided in this embodiment, before cooking, has its data acquisition module 500 acquire the height and diameter of the cookware 800. Based on the height of the cookware 800 acquired by the acquisition module 500, the controller controls the lifting component 300 to lower the support panel 200, allowing the bottom of the cookware 800 to extend into the receiving cavity 110. The controller also controls the adjusting component 400 to bring the second heating module 410 into contact with the side of the cookware 800 based on the diameter of the cookware 800 acquired by the acquisition module 500. During cooking, the induction cooker heats the bottom of the cookware 800 through the first heating module 210 and the side of the cookware 800 through the second heating module 410. This induction cooker reliably improves cooking efficiency and heating rate while adapting to cookware 800 of different sizes, enhancing the user experience.

[0087] In one embodiment, such as Figures 3-8As shown, the adjustment assembly 400 includes a connecting base 420 and a plurality of push rods 430. The connecting base 420 includes a connecting portion 421 and a plurality of telescopic rods 422, which are radially distributed around the connecting portion 421. The ends of the telescopic rods 422 away from the connecting portion 421 are connected one-to-one with the plurality of push rods 430, and the push rods 430 extend upward. Each push rod 430 is configured to drive at least one second heating module 410 to fit against the side of the cookware 800, and the controller is electrically connected to each of the plurality of telescopic rods 422.

[0088] Schematic, the connecting part 421 may include a connecting post and a connecting piece disposed at the bottom end of the connecting post. Multiple telescopic rods 422 may be arranged radially around the connecting piece and fixed to it. The number of telescopic rods 422 is not limited; for example, there may be eight telescopic rods 422 and eight push rods 430. The multiple telescopic rods 422 may be arranged at equal intervals around the center of the connecting piece. The end of each telescopic rod 422 away from the connecting part 421 may be connected to the bottom end of the corresponding push rod 430 by means of snap-fit ​​or fasteners.

[0089] When the support panel 200 causes the bottom end of the cookware 800 to be embedded into the receiving cavity 110, multiple second heating modules 410 are arranged around the outer side of the cookware 800. The controller can control multiple telescopic rods 422 to extend or retract synchronously according to the diameter of the cookware 800. When the multiple telescopic rods 422 extend synchronously, the connecting seat 420 can drive multiple push rods 430 to spread out; when the multiple telescopic rods 422 retract synchronously, the connecting seat 420 can drive multiple push rods 430 to retract. The multiple push rods 430 surround the outer side of the support panel 200. When the multiple push rods 430 retract, they can drive multiple second heating modules 410 to retract inward, so that the second heating modules 410 fit against the side wall of the cookware 800.

[0090] In this structure, the controller controls the telescopic rod 422 to retract, which can drive the push rod 430 to move laterally closer to the pot 800. The push rod 430 drives the second heating module 410 to move laterally closer to the pot 800, so that the second heating module fits against the side wall of the pot 800.

[0091] In a specific embodiment, such as Figures 5-18 As shown, the support panel 200 can drive the connecting seat 420 to rise and fall synchronously. Each push rod 430 is linked to multiple slide rods 440, which are arranged along the rising and falling direction of the support panel 200. Each slide rod 440 has a first end and a second end that are arranged opposite to each other, and the first end of each slide rod 440 is connected to a second heating module 410.

[0092] Optionally, the bottom end of the first heating module 210 is connected to the top end of the connecting part 421, so that when the support panel 200 is raised or lowered, it drives the second lifting platform to rise and fall synchronously. After the support panel 200 drives the bottom end of the pot 800 into the receiving cavity 110, multiple second heating modules 410 are arranged in multiple layers and columns around the pot 800, and each of the multiple second heating modules 410 is connected to multiple slide rods 440 in a one-to-one correspondence. The number of layers of the second heating modules 410 can be set as needed, and the number of columns of the second heating modules 410 can be set according to the number of push rods 430. It can be understood that the multiple slide rods 440 are also arranged in multiple layers and columns, and each push rod 430 can drive a column of slide rods 440 to move laterally, thereby driving a column of second heating modules 410 to move laterally.

[0093] The fixed platform 100 is provided with a limiting wall 120 in the receiving cavity 110. The slide rod 440 is provided through the limiting wall 120. The push rod 430 is located on the side of the slide rod 440 away from the second heating module 410. The push rod 430 has a protrusion 431 protruding on the side facing the limiting wall 120.

[0094] For example, when the support panel 200 causes the bottom end of the cookware 800 to be inserted into the receiving cavity 110, the limiting wall 120 can be arranged around the cookware 800. A guide hole can be formed on the limiting wall 120, through which the slide rod 440 passes. The guide hole guides the slide rod 440, allowing it to move laterally only along the extension direction of the guide hole. The protrusion 431 can be integrally formed on the side of the push rod 430 facing the limiting wall 120.

[0095] When the protrusion 431 moves downward past the second end, the protrusion 431 pushes the second end, and the slide rod 440 drives the second heating module 410 to move laterally to fit the side of the pot 800.

[0096] It is worth mentioning that before the connecting seat 420 drives the push rod 430 to start lifting and lowering, in order to adapt to different pot sizes 800, the controller first controls the telescopic rods 422 of the connecting seat 420 to shorten. At this time, the connecting seat 420 drives the multiple push rods 430 connected to it to retract inward, so as to ensure that the second heating module 410 connected to the slide rod 440 can fit tightly against the side of the pot 800 after the subsequent push rod 430 drives the slide rod 440 to move laterally.

[0097] The number of layers of the second heating module 410 that are in close contact with the cookware 800 can be controlled according to the depth to which the cookware 800 is embedded in the receiving cavity 110. For example, when the support panel 200 lowers the bottom of the cookware 800 below the uppermost layer of the second heating module 410, the support panel 200 causes the protrusion 431 of the push rod 430 to pass over the uppermost sliding rod 440. As the protrusion 431 passes downwards over the uppermost sliding rod 440, it can cause the uppermost sliding rod 440 to move towards the cookware 800, thus causing the second heating module 410 connected to it to be in close contact with the side of the cookware 800. As the depth of the cookware 800 embedded in the receiving cavity 110 increases, the number of layers of the second heating module 410 that are in close contact with the cookware 800 increases via the push rod 430 and the sliding rod 440. Since the controller can control the depth at which the cookware 800 is embedded in the receiving cavity 110 according to the height of the cookware 800, the multiple second heating modules 410 can selectively adhere to the cookware 800 according to its height. Schematic, each second heating module 410 is electrically connected to the controller, and the controller can control only the second heating modules 410 that are adhered to the cookware 800 to heat the cookware 800.

[0098] In this embodiment, the induction cooker uses a multi-stage heating mode to heat the sides of the cookware. Multiple second heating modules 410 can selectively adhere to and heat the cookware 800 according to its height, adapting to different cookware heights while ensuring sufficient heating of the cookware 800's sidewalls. Furthermore, if the cookware 800 is relatively short or its embedding depth in the receiving cavity 110 is shallow, not all second heating modules 410 need to be heated, thus saving energy.

[0099] In other embodiments, multiple second heating modules 410 may form only one layer, and each second heating module 410 is fixedly connected to a push rod 430. The extension and retraction of the telescopic rod 422 drives the push rod 430 to move laterally, thereby causing the second heating module 410 on the push rod 430 to fit tightly against the pot 800.

[0100] In one possible implementation, such as Figures 6-19 As shown, the adjustment assembly 400 also includes a limiting member 460 and an elastic member 470. The limiting member 460 is slidably mounted on the limiting wall 120, and the slide rod 440 has a toothed portion 441 on the side facing the limiting member 460. The limiting member 460 is configured to engage with the toothed portion 441 to limit the slide rod 440 from moving away from the cookware 800.

[0101] In one possible implementation, a limiting member 460 is provided above each slide rod 440, and the limiting member 460 can slide up and down relative to the limiting wall 120. When the push rod 430 drives the slide rod 440 to slide closer to the pot 800, the limiting member 460 slides downward, so that the bottom end of the limiting member 460 engages with the toothed portion 441 on the slide rod 440. The engagement between the limiting member 460 and the toothed portion 441 can limit the slide rod 440 from moving away from the pot 800, ensuring that the second heating module 410 connected to the slide rod 440 is reliably attached to the pot 800.

[0102] The elastic element 470 is connected between the slide bar 440 and the limiting wall 120, and the elastic element 470 is configured to apply a spring force away from the cookware 800 to the slide bar 440.

[0103] For example, the elastic element 470 is sleeved on the slide rod 440, and the side wall of the slide rod 440 has a protrusion. One end of the elastic element 470 abuts against the limiting wall 120, and the other end of the elastic element 470 abuts against the protrusion. When the push rod 430 drives the slide rod 440 to move closer to the cookware 800, the slide rod 440 overcomes the elastic force of the elastic element 470. When the limiting member 460 disengages from the toothed portion 441 of the slide rod 440, the elastic force of the elastic element 470 can drive the slide rod 440 to return to its original position. Optionally, a driving member can be installed on the limiting wall 120. This driving member is connected to the limiting member 460, and the driving member can drive the limiting member 460 to slide relative to the limiting wall 120.

[0104] like Figure 6 and Figure 7 As shown, when both the first heating module 210 and the connecting seat 420 are in the highest position, there is a gap between the first heating module 210 and the connecting part 421 in the vertical direction.

[0105] Figure 7 , Figure 8 and Figure 10 As shown, the bottom surface of the first heating module 210 is provided with a boss 211, and the top end of the connecting part 421 is provided with a locking hole 4211. The boss 211 extends into the locking hole 4211 and is detachably connected to the connecting part 421.

[0106] The boss 211 can be a columnar structure, and the locking hole 4211 can be formed at the top of the connecting column, with the boss 211 positioned opposite to the locking hole 4211. When the lifting assembly 300 lowers the support panel 200 and the first heating module 210, the boss 211 of the first heating module 210 can extend into the locking hole 4211. When the bottom surface of the first heating module 210 is in contact with the top of the connecting part 421, the boss 211 can be locked with the locking hole 4211. In one possible implementation, after the boss 211 extends into the locking hole 4211, it can be fixed to the connecting part 421 by magnetic attraction or snap-fit. After the boss 211 extends into the locking hole 4211 and connects to the connecting part 421, the lifting assembly 300 can drive the support panel 200, the first heating module 210, and the connecting seat 420 to rise and fall synchronously.

[0107] When the lifting assembly 300 causes the support panel 200 to begin descending, the first heating module 210, fixed below the support panel 200, also moves downwards. For example... Figure 9 and Figure 10 As shown, when the boss 211 on the bottom surface of the first heating module 210 extends into the locking hole 4211 at the top of the connecting part 421, the boss 211 connects with the connecting part 421, thus fixing the support panel 200, the first heating module 210, and the connecting seat 420. At this time, the lifting assembly 300 can drive the multiple push rods 430 connected to the connecting seat 420 to rise and fall synchronously with the support panel 200. Figures 9-18 As shown, as the push rod 430 descends, it can drive multiple second heating modules 410 to adhere to the side of the pot 800 layer by layer from top to bottom.

[0108] A limiting structure is provided between the connecting seat 420 and the fixed platform 100. The limiting structure is configured to limit the connecting seat 420 to the fixed platform 100 when the top of the push rod 430 abuts against the inner top wall of the receiving cavity 110.

[0109] The limiting structure can fix the top end of the push rod 430 to the inner top wall of the receiving cavity 110. In one possible implementation, the limiting structure includes a magnetic element at the top end of the push rod 430 and a magnetic element on the inner top wall of the receiving cavity 110. After the top end of the push rod 430 abuts against the inner top wall of the receiving cavity 110, it is fixed by the magnetic attraction of the magnetic element. When the lifting assembly 300 lowers the support panel 200, the first heating module 210, and the connecting seat 420, the top end of the push rod 430 can be disengaged from the inner top wall of the receiving cavity 110.

[0110] In this structure, after the lifting assembly 300 lowers the support panel 200 and the first heating module 210 to a certain height, the first heating module 210 connects to the connecting part 421 of the connecting seat 420. This distance ensures that the adjusting assembly 400 will only move the second heating module 410 laterally to fit against the side wall of the cookware 800 after the support panel 200 is lower than the second heating module 410, thus avoiding interference between the second heating module 410 and the support panel 200. Assembly between the first heating module 210 and the connecting part 421 is relatively easy, and the limiting structure between the connecting seat 420 and the fixed platform 100 ensures a smooth connection between the first heating module 210 and the connecting part 421.

[0111] In one specific implementation, such as Figure 7 , Figure 10 and Figure 14 As shown, at least one of the protrusion 431 and the second end is provided with a guide surface 450, which is configured to drive the slide bar 440 to move away from the push bar 430 when the protrusion 431 presses the second end downward.

[0112] The guide surface 450 may be provided only on the protrusion 431 or only on the second end of the slide rod 440, or it may be provided on both the protrusion 431 and the second end of the slide rod 440. The guide surface 450 may be an inclined surface or an arc surface, and there is no specific limitation. When the guide surface 450 is provided on the protrusion 431, the guide surface 450 is located on the bottom surface of the protrusion 431 facing the limiting wall 120; when the guide surface 450 is provided on the second end of the slide rod 440, the guide surface 450 is located on the top surface of the second end of the slide rod 440.

[0113] When the protrusion 431 moves downward to abut against the second end of the slide bar 440, the two come into contact with each other through the guide surface 450. The protrusion 431 applies a force away from the push rod 430 to the second end of the slide bar 440 through the guide surface 450, causing the slide bar 440 to drive the second heating module 410 to move laterally.

[0114] With the above configuration, when the protrusion 431 passes the second end of the slide bar 440, it can drive the slide bar 440 to move laterally.

[0115] In one embodiment, such as Figure 4 , Figure 5 and Figure 20 As shown, the lifting assembly 300 includes a rack 310, a motor 320, and a gear 330. The rack 310 is fixedly installed in the receiving cavity 110 and extends vertically. Multiple racks 310 are arranged around the support panel 200.

[0116] Gear 330 is rotatably mounted on support panel 200 and meshes with rack 310, and motor 320 is mounted on support panel 200 and connected to gear 330.

[0117] For example, a mounting base is provided on the bottom surface of the support panel 200, and the gear 330 is rotatably mounted on the mounting base. The rotation axis of the gear 330 extends horizontally. The gear 330 may be provided with a connecting shaft coaxial with its main body. The body of the motor 320 is fixedly mounted on the bottom surface of the support panel 200, and the output shaft of the motor 320 can be connected to the connecting shaft through a coupling. The number of motors 320, gears 330, and racks 310 is the same, and each motor 320 can drive one gear 330 to rotate, causing it to move up and down on the corresponding rack 310.

[0118] In this embodiment, when the motor 320 drives the gear 330 to rotate, the meshing between the gear 330 and the rack 310 can drive the support panel 200 to rise and fall. Compared to using multiple connecting rods to drive the support panel 200, this method of raising and lowering the support panel 200 through the engagement of the gear 330 and rack 310 not only offers higher transmission accuracy and improved lifting precision, enabling more accurate positioning, but also provides smoother transmission, less vibration and noise, more stable operation, less drive wear, and a longer lifespan, making it suitable for long-term use.

[0119] In one embodiment, such as Figure 3 and Figure 20 As shown, a guide rod 600 extending vertically is provided in the receiving cavity 110, and a braking assembly 700 is installed on the support panel 200. The support panel 200 and the braking assembly 700 are slidably connected to the guide rod 600, and the braking assembly 700 is electrically connected to the controller.

[0120] Optionally, both ends of each guide rod 600 are fixed to the fixed platform 100. In one possible implementation, a semi-circular groove can be provided on the outer circumferential edge of the support panel 200 to cooperate with and limit the guide rod 600. In another possible implementation, a through hole can be provided on the support panel 200, through which the guide rod 600 passes. The guide rod 600 can guide the lifting and lowering of the support panel 200. When the lifting assembly 300 drives the support panel 200 to lift and lower, both the support panel 200 and the braking assembly 700 slide relative to the guide rod 600. Under the limitation of the guide rod 600, the support panel 200 moves up and down along the extension direction of the guide rod 600 (perpendicular to the direction of the support panel 200).

[0121] The braking assembly 700 has a braking state and a released state. When the braking assembly 700 is in the braking state, the braking assembly 700 is locked to the guide rod 600; when the braking assembly 700 is in the released state, the braking assembly 700 is unlocked from the guide rod 600.

[0122] Schematic illustration: The braking component 700 is electrically connected to the controller, which can control the state of the braking component 700. When the height of the support panel 200 needs to be adjusted, the controller first controls the braking component 700 to change from the braking state to the released state. At this time, the lifting component 300 can drive the support panel 200 to rise or fall. After the support panel 200 has risen or fallen to the preset stroke, the controller controls the braking component 700 to change from the released state to the braking state, fixing the height of the support panel 200 through the cooperation between the braking component 700 and the guide rod 600. The controller can also precisely brake according to the height of the pot 800.

[0123] In a specific embodiment, such as Figure 20 and Figure 21 As shown, the braking assembly 700 includes a limiting seat 710, a limiting cover 720, and an elastic component. The limiting seat 710 is sleeved on the guide rod 600, and a notch 711 is formed on the side wall of the limiting seat 710 to expose the guide rod 600. The limiting cover 720 is connected to the limiting seat 710 through the elastic component, and the position of the limiting cover 720 is directly opposite the notch 711.

[0124] The limiting seat 710 has a cylindrical structure, the top of which can be fixed to the bottom surface of the support panel 200, and the guide rod 600 passes through this cylindrical structure. Exemplarily, the elastic component includes an adjustable rod 731 and a spring 732 sleeved on the adjustable rod 731. The adjustable rod 731 is telescopic, and its two ends are respectively connected to the limiting seat 710 and the limiting cover 720. The two ends of the spring 732 abut against the limiting seat 710 and the limiting cover 720, respectively. The elastic component can apply a spring force away from the limiting seat 710 to the limiting cover 720.

[0125] One of the limit seat 710 and the limit cover 720 is equipped with an electromagnet 741, and the other is equipped with a ferromagnetic component 742 attracted by the power supply magnet 741. The electromagnet 741 is electrically connected to the controller.

[0126] The ferromagnetic component 742 can be either a magnet or an iron block. For example, such as... Figure 20 and Figure 21As shown, electromagnet 741 is mounted on limiting seat 710, and ferromagnetic component 742 is mounted on limiting cover 720. There are two electromagnets 741 and two ferromagnetic components 742. Both limiting seat 710 and limiting cover 720 are provided with mounting holes. The two electromagnets 741 are respectively mounted in the mounting holes on opposite sides of the limiting seat 710, and the two ferromagnetic components 742 are respectively mounted in the mounting holes on opposite sides of the limiting cover 720. In other embodiments, electromagnet 741 can also be mounted on limiting cover 720, and correspondingly, ferromagnetic component 742 is mounted on limiting seat 710.

[0127] When the braking assembly 700 is in the braking state, the electromagnet 741 attracts the ferromagnetic component 742, thereby causing the limiting cover 720 to press against the guide rod 600. When the braking assembly 700 is in the released state, the elastic component causes the limiting cover 720 to disengage from the guide rod 600.

[0128] The controller controls the energization of the electromagnet 741 to move the limit cover 720 closer to or further away from the limit seat 710, thereby changing the state of the braking assembly 700. Specifically, when the support panel 200 needs to be raised or lowered, the electromagnet 741 is not energized, and there is no magnetic attraction between the electromagnet 741 and the ferromagnetic component 742, meaning the braking assembly 700 is in a released state. When the raising or lowering of the support panel 200 is complete and height limiting of the support panel 200 is required, the electromagnet 741 is energized, and a magnetic attraction is generated between the electromagnet 741 and the ferromagnetic component 742, meaning the braking assembly 700 is in a braking state. The braking assembly 700 has high reliability and can achieve frequent start-stop operation.

[0129] Figure 3 , Figure 20 and Figure 21 As shown, there are multiple guide rods 600, which are arranged at intervals around the support panel 200. The number of guide rods 600 is not limited; those skilled in the art can set them as needed, for example... Figure 20 As shown, four guide rods 600 can be provided circumferentially around the support panel 200. Multiple guide rods 600 can be arranged at equal intervals around the support panel 200.

[0130] The support panel 200 is slidably connected to multiple guide rods 600. Multiple braking components 700 are mounted on the support panel 200, and each braking component 700 is slidably connected to one of the guide rods 600. The guide rods 600 also limit the movement of the support panel 200 relative to the fixed platform 100. The number of braking components 700 is the same as the number of guide rods 600. The cooperation between the multiple braking components 700 and the multiple guide rods 600 more reliably limits the height of the support panel 200.

[0131] Each braking assembly 700 is equipped with a sensor to obtain the travel distance of the braking assembly 700 sliding on the guide rod 600.

[0132] Optionally, the sensor can be a linear potentiometer, which is mounted on the limit seat 710 of the braking assembly 700. When the lifting assembly 300 drives the braking assembly 700 to slide on the corresponding guide rod 600, the sensor can obtain the sliding stroke of the braking assembly 700. The braking assembly 700 can detect the lifting stroke of the support panel 200 through the sensor. By using multiple braking assemblies 700, the lifting positions of multiple points on the support panel 200 can be realized, improving the positioning accuracy.

[0133] During the lifting process of the lifting assembly 300 driving the support panel 200 to rise and fall, when the braking assembly 700 slides on the guide rod 600 to reach the lifting stroke of the support panel 200, the controller controls the braking assembly 700 to change from a released state to a braking state. Through the cooperation between multiple braking assemblies 700 and multiple guide rods 600, the lifting positions of multiple points on the support panel 200 can be made consistent, avoiding instability in the lifting position of the support panel 200 due to overload of the lifting assembly 300.

[0134] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
