[0002] With the continuous development of smart home technology, lift cabinets, as a new type of kitchen furniture, are gradually gaining popularity among consumers due to their advantages such as space saving and convenient access. However, in actual use, the lowering process of lift cabinets has some problems. In particular, when the cabinet encounters a foreign object during the descent, it fails to stop in time, causing the cabinet to collide with the foreign object and cause damage to the cabinet. This situation not only affects the normal use of the cabinet, but also may damage the items stored in the cabinet. In addition, if the foreign object is a human body or a pet, it may also pose a safety hazard. Most lift cabinets currently on the market lack effective anti-collision functions and are unable to stop the descent action in time when encountering an obstacle, which seriously affects the product safety and user experience.

For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0036] The following is combined with Figures 1 to 5 The technical solution of the utility model is further illustrated through specific implementation methods.

[0037] A lifting cabinet with an anti-collision function, comprising an outer cabinet body 1, an inner cabinet body 2, an anti-collision bottom plate 3, a driving device, an electric control component, a floating base 4, a Hall plate 51 and a magnet 52;

[0038] The inner cabinet 2 is installed inside the outer cabinet 1, and the driving device is used to drive the inner cabinet 2 to rise and fall through the bottom opening of the outer cabinet 1;

[0039] The floating base 4 includes a fixed base 41, a connecting base 42 and an elastic connecting member 43. The fixed base 41 is connected to the inner cabinet 2, the connecting base 42 is connected to the anti-collision bottom plate 3, and the connecting base 42 is connected to the fixed base 41 via the elastic connecting member 43. The connecting base 42 reciprocates relative to the fixed base 41.

[0040] The Hall plate 51 and the magnet 52 are mounted on the fixing base 41 and the connecting base 42 respectively;

[0041] The Hall plate 51 and the driving device are electrically connected to the electronic control component respectively.

[0042] By introducing the design of an anti-collision base plate 3 and a floating base 4 (including a fixed base 41, a connecting base 42 and an elastic connector 43), under normal circumstances, the connecting base 42 maintains a relatively fixed positional relationship with the fixed base 41; when the lifting cabinet encounters a foreign object during the descent process, the anti-collision base plate 3 will first contact the foreign object, causing the connecting base 42 to move up and down relative to the fixed base 41. Since a Hall plate 51 is installed on the fixed base 41 and a magnet 52 is installed on the connecting base 42, when the connecting base 42 is displaced, the relative position between the Hall element 511 and the magnet 52 will change, thereby generating a detectable electrical signal change. By monitoring this electrical signal change, the electronic control component can promptly determine whether a collision has occurred and immediately stop the operation of the drive device when necessary.

[0043] By installing a Hall effect plate 51 and magnet 52 on the floating base 4 of the lift cabinet, precise monitoring of the lifting process is achieved. When the inner cabinet body 2 is lowered and the anti-collision base plate 3 encounters foreign objects and encounters resistance during its descent, causing the connecting seat 42 to shift (upward) relative to the fixed seat 41, the relative position of the Hall effect element 511 on the Hall effect plate 51 and the magnet 52 will change. This change is quickly sensed by the electronic control component, which immediately triggers the drive device to stop working, effectively preventing the inner cabinet body 2 from colliding with foreign objects during the lifting process, protecting the cabinet's integrity and extending its service life.

[0044] The anti-collision function of the lift cabinet not only protects the cabinet itself, but also avoids noise and possible user injury caused by collision, thereby improving the user experience. At the same time, intelligent control also makes operation easier, in line with the development trend of modern smart homes.

[0045] Furthermore, the connecting seat 42 is installed on the bottom of the inner cabinet 2 , and the fixing seat 41 is installed on the top of the anti-collision bottom plate 3 .

[0046] By installing the connecting base 42 at the bottom of the inner cabinet 2 and the fixing base 41 on top of the anti-collision base 3, this layout makes the floating base 4 assembly more compact while maintaining structural stability. During the lifting and lowering of the inner cabinet 2, the connecting base 42 moves with it, while the fixing base 41 remains relatively stable on the anti-collision base 3, providing effective support and cushioning for the inner cabinet.

[0047] By positioning the anti-collision base plate 3 at the very bottom, it becomes the front line of defense for the entire anti-collision system. When the inner cabinet 2 encounters a foreign object during its descent, the anti-collision base plate 3 first contacts the object and transmits the impact force to the connecting base 42 and the fixing base 41 via the elastic connector 43. This design more effectively absorbs collision energy, minimizing damage to the inner cabinet and the cabinet as a whole.

[0048] Further, the connecting seat 42 comprises a connecting bottom plate 421 and a guide column 422, the guide column 422 is arranged on the top surface of the connecting bottom plate 421, and the connecting bottom plate 421 is connected with the anti-collision bottom plate 3;

[0049] The fixing seat 41 comprises a connecting top plate 411 and a hollow guide cylinder 412, the guide cylinder 412 is arranged on the bottom surface of the connecting top plate 411, and the guide cylinder 412 is arranged correspondingly with the guide column 422;

[0050] The connecting top plate 411 covers the connecting bottom plate 421, the guide column 422 is movably arranged in the hollow part of the guide cylinder 412, the elastic connecting piece 43 is sleeved on the outside of the guide column 422 and located at the bottom of the guide cylinder 412.

[0051] The guide column 422, the guide cylinder 412 and the elastic connecting piece 43 cooperatively form an effective guiding, buffering and resetting mechanism. When the anti-collision bottom plate 3 is impacted by external force, the guide column 422 moves up and down in the guide cylinder 412, and the elastic connecting piece 43 plays a buffering role, thereby reducing the impact force. At the same time, the resetting function of the elastic connecting piece 43 ensures that the guide column 422 can return to the original position after impact, ensuring the stability and anti-collision function of the lifting cabinet, and realizing the effective protection and automatic resetting function of the lifting cabinet when it is impacted by external force.

[0052] The corresponding arrangement of the guide column 422 and the guide cylinder 412 not only provides linear guidance during lifting, but also enhances the overall stability of the floating base 4 structure, so that the lifting cabinet can better maintain its original state when subjected to external force. The elastic connecting piece 43 enables the connecting seat 42 to quickly and sensitively respond to changes through elastic deformation when the inner cabinet body 2 (anti-collision bottom plate 3) encounters foreign matter during the descending process. This deformation will immediately change the relative position between the Hall plate 51 and the magnet 52, thereby triggering the shutdown instruction of the electric control assembly. The sleeved position of the elastic connecting piece 43 (located at the bottom of the guide cylinder 412) ensures that it can fully play its buffering function when subjected to external force, further improving the accuracy and reliability of the anti-collision response. Further, the elastic connecting piece 43 not only can provide buffering action when encountering foreign matter, but also can help the inner cabinet body 2 to return to the initial position after completing the lifting action. This resetting function ensures that the lifting cabinet can maintain its original performance and precision after multiple uses.

[0053] Preferably, the elastic connecting piece 43 is a spring, which is convenient to sleeve on the outside of the guide column 422.

[0054] Furthermore, a bolt 424 is detachably provided on the top of the guide column 422 , and a limiting portion 413 is provided on the bottom of the guide cylinder 412 . The head of the bolt 424 is limited to the upper portion of the limiting portion 413 .

[0055] A bolt 424 is provided at the top of the guide column 422, which allows for easy disassembly and adjustment. A limiting portion 413 is provided at the bottom of the guide cylinder 412. When the guide column 422 moves up and down in the guide cylinder 412, the head of the bolt 424 will be restricted by the limiting portion 413. By detachably providing the bolt 424 at the top of the guide column 422 and providing the limiting portion 413 at the bottom of the guide cylinder 412, a stable connection between the guide column 422 and the guide cylinder 412 is achieved. This connection method not only ensures structural stability during the lifting process, but also allows fine-tuning or disassembly when necessary to adapt to different installation or maintenance requirements. The head of the bolt 424 is limited to the upper part of the limiting portion 413. This design prevents the bolt 424 from accidentally falling off during the lifting process, further enhancing the reliability of the connection.

[0056] Furthermore, a mounting hole 4111 is provided at the connection between the connecting top plate 411 and the guide cylinder 412 . The mounting hole 4111 is communicated with the hollow portion of the guide cylinder 412 . A screw cover 414 is detachably provided on the mounting hole 4111 .

[0057] The design of the mounting hole 4111 allows the user to easily access the interior of the guide cylinder 412 by removing the screw cover 414 without destroying the original structure. This provides the user with the possibility of internal inspection, repair or replacement of parts when necessary, improving the maintainability of the lifting cabinet.

[0058] When the screw cover 414 is closed, it can tightly cover the mounting hole 4111, thereby preventing dust, moisture or other pollutants from entering the interior of the guide cylinder 412. This helps to keep the lifting cabinet clean and stable in performance, while extending the service life of the components.

[0059] In summary, by providing mounting holes 4111 and screw caps 414 at the junction of top plate 411 and guide cylinder 412, the improved technical solution enhances the maintainability of the lift cabinet, simplifies the installation and adjustment process, improves the flexibility and adaptability of the structure, enhances the sealing and protective properties of the structure, and improves the overall aesthetics. These improvements significantly improve the performance, usability, and appearance of the lift cabinet.

[0060] Furthermore, the number of the guide posts 422 is two, and the two guide posts 422 are arranged on the top surface of the connecting bottom plate 421 in a front-to-back manner.

[0061] There are two guide cylinders 412 , which are arranged on the bottom surface of the connecting top plate 411 in a front-to-back manner.

[0062] The two guide posts 422 correspond to the two guide cylinders 412 one by one.

[0063] By providing two front and rear opposing guide posts 422 and guide cylinders 412, the stability of the lifting cabinet during the lifting process is significantly improved. This dual-guide design can ensure smooth and safe lifting movements.

[0064] The dual-guide design not only enhances stability but also improves the lifting accuracy of the lifting cabinet. Since both guide posts 422 are precisely guided by the corresponding guide cylinders 412, the trajectory of the inner cabinet 2 during the lifting process is more stable and controllable, reducing errors caused by shaking or offset.

[0065] In terms of collision avoidance, the dual-guide design ensures more accurate and reliable changes in the relative position between the Hall plate 51 and the magnet 52. If the inner cabinet encounters a foreign object during its descent, the obstruction of the two guide posts 422 more accurately reflects the relative position of the Hall plate 51 and the magnet 52, triggering a shutdown command for the electronic control assembly to prevent a collision.

[0066] Furthermore, the connecting bottom plate 421 is provided with a magnet mounting groove 4211, and the magnet 52 can be mounted in the magnet mounting groove 4211 in an adjustable manner.

[0067] The position of the Hall element 511 of the Hall plate 51 corresponds to the position of the magnet 52 in a vertical direction.

[0068] By providing a magnet mounting slot 4211 on the connecting base plate 421 and allowing the magnet 52 to be mounted in the magnet mounting slot 4211 so that it can be adjusted up and down, the position of the magnet 52 can be flexibly adjusted. This allows the position of the magnet 52 to be adjusted as needed in different usage scenarios, ensuring that the Hall element 511 can accurately detect changes in the magnet's position, thereby improving the accuracy and reliability of anti-collision detection. This solves the problem of inflexible detection caused by the fixed position of the magnet in lift cabinets with anti-collision functions, making anti-collision detection more accurate and reliable, and improving the safety of the product.

[0069] To further illustrate, the relative position of the magnet 52 and the Hall element 511 on the Hall plate 51 can ensure that when the anti-collision base plate 3 is collided, the relative position change between the magnet 52 and the Hall element 511 can be detected quickly and accurately, thereby improving the sensitivity of anti-collision detection.

[0070] Further, the magnet 52 is detachably mounted on an adjusting nut 425, and the adjusting nut 425 is threadedly connected with the magnet mounting groove 4211.

[0071] The thread connection between the adjusting nut 425 and the magnet mounting groove 4211 is designed so that the user can adjust the height of the magnet 52 by rotating the adjusting nut 425 according to actual needs. This provides greater flexibility for the Hall induction assembly, so that the triggering conditions of the anti-collision function can be accurately adjusted according to different use scenarios and the weight of the cabinet body and the anti-collision bottom plate.

[0072] The magnet 52 is detachably mounted on the connecting bottom plate 421 through the adjusting nut 425, which makes it more convenient to install, disassemble or replace the magnet 52. Users can easily complete these tasks without the need for complex tools or operations, thereby reducing maintenance costs and time.

[0073] Further, the number of the magnet 52 is two, and the two magnets 52 are oppositely mounted on the connecting bottom plate 421.

[0074] The Hall plate 51 includes two Hall elements 511, and the two Hall elements 511 correspond to the two magnets 52 respectively.

[0075] By arranging two oppositely arranged magnets 52 and two corresponding Hall elements 511, more detection points are provided for the detection assembly, so that the detection accuracy and sensitivity of the anti-collision function of the lifting cabinet are higher. When the inner cabinet body 2 (anti-collision bottom plate 3) encounters a foreign object during the descending process, the foreign object can be detected by at least one combination of the magnet 52 and the Hall element 511, regardless of the position of the foreign object, so as to timely trigger the stop command of the electric control assembly to avoid collision. This design can more accurately reflect the position and state of the inner cabinet body, thereby reducing the risk of collision caused by misjudgment or omission.

[0076] The technical principles of the present application are described above in combination with specific embodiments. These descriptions are only to explain the principles of the present application, and cannot be interpreted in any way as a limitation on the protection scope of the present application. Based on the above explanation, those skilled in the art can think of other specific embodiments of the present application without creative labor, and these embodiments will fall within the protection scope of the present application.
