[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] See Figures 1 to 4 As shown, the climbing device 100 according to this application can be applied to the cleaning equipment 500. With the combined action of the cleaning equipment 500 and the climbing device 100, the cleaning equipment 500 can move on structures with height differences, such as stairs (for example, see...). Figure 2 The movement of the cleaning equipment 500 climbing the stairs is shown in the order of (A) to (F). Similarly, Figure 2 The movement of cleaning equipment 500 from top to bottom of the stairs is shown in the order of F to A.

[0056] See Figures 3 to 7As shown, the climbing device 100 according to this application includes a holding mechanism 1 and a lifting mechanism 2. The lifting mechanism 2 and the holding mechanism 1 are configured to slide together in the length direction (i.e., the first direction, X direction as shown in the figure) of the climbing device 100, allowing the holding mechanism 1 and the lifting mechanism 2 to move relative to each other in the length direction of the climbing device 100. The lifting mechanism 2 also drives the holding mechanism 1 to move in the height direction (i.e., the second direction, Z direction as shown in the figure) of the climbing device 100 through a telescopic action. Furthermore, the holding mechanism 1 is used to hold the cleaning device 500, so that the cleaning device 500 is fixedly connected to the holding mechanism 1.

[0057] Specifically, see Figure 1 As shown, the cleaning device 500 and the climbing device 100 are separate units in normal operation, meaning the cleaning device 500 and the climbing device 100 are two independent entities. This allows the cleaning device 500 to move synchronously with the climbing device 100 during cleaning operations. This avoids placing a large load on the cleaning device 500 and also prevents the overall size of the cleaning device 500 from becoming too large (compared to its size when the cleaning device 500 and climbing device 100 are combined), thus giving the cleaning device 500 greater flexibility during cleaning operations.

[0058] See Figure 1 As shown, the holding mechanism 1 has a holding space 10. During the assembly of the cleaning device 500 and the climbing device 100: the cleaning device 500 moves into the holding space 10 through the opening 101, thus embedding the cleaning device 500 within the holding mechanism 1. Furthermore, the holding mechanism 1 and the cleaning device 500 are fixedly connected, preventing the cleaning device 500 from detaching from the holding mechanism 1. In other words, when the holding mechanism 1 is fixedly connected, the cleaning device 500 is fixedly assembled to the climbing device 100, establishing a combined connection between the two. Similarly, during the disconnection process between the cleaning device 500 and the climbing device 100: the fixed connection between the holding mechanism 1 and the cleaning device 500 is released, allowing the cleaning device 500 to move out of the holding space 10 through the opening 101, thus separating the cleaning device 500 and the climbing device 100 back into two independent entities.

[0059] See Figure 2 As shown, Figure 2 The movement of the cleaning equipment 500 climbing the stairs is shown in the order of (A) to (F). Figure 2As shown in (A), the cleaning device 500 and the climbing device 100 are combined, and the lifting mechanism 2 is at its smallest size in the height direction, so that the bottom of the lifting mechanism 2 is separated from the ground, preventing the climbing device 100 from contacting the ground. This reduces the resistance encountered by the cleaning device 500 in moving the climbing device 100, and improves the smoothness of the movement of the cleaning device 500.

[0060] Combination Figure 2 As shown in (A) to (B), when the cleaning equipment 500 is moved to a suitable position, the lifting mechanism 2 begins to extend in the vertical direction, so that the bottom of the lifting mechanism 2 first makes contact with the ground, allowing the opposite side to apply a supporting force to the climbing device 100. After the bottom of the lifting mechanism 2 is fully in contact with the ground, the lifting mechanism 2, which is in a continuously extended state in the vertical direction, begins to lift the holding mechanism 1, so that the holding mechanism 1 lifts the cleaning equipment 500 upward, achieving the effect of raising the cleaning equipment 500 in the vertical direction. When the bottom of the cleaning equipment 500 is level with or higher than the upper surface of the target step, the lifting mechanism 2 stops lifting the holding mechanism 1, so that the cleaning equipment 500 is maintained at the current height.

[0061] Next, combine Figure 2 As shown in (B) to (C), the holding mechanism 1 and the lifting mechanism 2 move relative to the lifting mechanism 2 in the length direction of the climbing device 100, so that the holding mechanism 1 moves forward in the length direction of the climbing device 100, so that the holding mechanism 1 drives the cleaning device 500 to move above the target step located in front of it.

[0062] Next, combine Figure 2 As shown in (C) to (D), the lifting mechanism 2 begins to shorten in the height direction to minimize the size of the lifting mechanism 2 in the height direction, so that the bottom of the lifting mechanism 2 is separated from the ground and eventually level with or higher than the upper surface of the target step.

[0063] Next, combine Figure 2 As shown in (D) to (E), the holding mechanism 1 and the lifting mechanism 2 move relative to the lifting mechanism 2 in the length direction of the climbing device 100, so that the lifting mechanism 2 moves forward in the length direction of the climbing device 100, so that the climbing device 100 moves above the target step.

[0064] In this way, the cleaning equipment 500, with the help of the climbing device 100, successfully climbed from the ground to the target steps. Figure 2As shown in (E) to (F), the cleaning equipment 500 climbs towards the next target step with the aid of the climbing device 100. Thus, the cleaning equipment 500, with the aid of the climbing device 100, can climb structures with varying heights, such as stairs. Similarly, the cleaning equipment 500, with the aid of climbing, can also move from above to below on structures with varying heights, such as stairs.

[0065] It should also be noted that: because the lifting mechanism 2 and the holding mechanism 1 are configured to slide together along the length of the climbing device 100, the lifting mechanism 2 and the holding mechanism 1 can move relative to each other along the length of the climbing device 100, thereby enabling the holding mechanism 1 to move the cleaning device 500 relative to the lifting mechanism 2 along the length. Thus, the length movement requirement of the cleaning device 500 is entirely met by the internal structural cooperation of the climbing device 100, without requiring the cleaning device 500 itself to possess any adaptation structure related to "length movement".

[0066] Based on this, regardless of whether it is a common round cleaning device 500 on the market, or a model with different contours such as rectangular or square, or a product with different weight specifications such as lightweight or medium-heavyweight, as long as it can be initially positioned and fixed through the universal holding space 10 of the holding mechanism 1, it can passively follow the holding mechanism 1 to achieve precise length direction displacement by means of the sliding connection between the lifting mechanism 2 and the holding mechanism 1. This design of the climbing device 100 completely transforms the "movement adaptation requirements of the cleaning device 500" into the "internal structural design requirements of the climbing device 100", so that no matter what the original design of the existing cleaning device 500 is, as long as its external dimensions are within the adaptation range of the holding space 10, it can be smoothly moved in the length direction through the climbing device 100 without any targeted structural modifications, further expanding the adaptation range of the climbing device 100 to the existing cleaning device 500.

[0067] In summary, the climbing device 100 according to this application, by being equipped with a holding mechanism 1 and a lifting mechanism 2, can assist the cleaning equipment 500 in climbing structures with height differences such as stairs, and the climbing device 100 is also compatible with a variety of cleaning equipment 500, with a wide range of applicability.

[0068] See Figure 2As shown, in some embodiments of this application, the lifting mechanism 2 may include two lifters 20, which are respectively disposed on both sides of the holding mechanism 1 in the width direction (i.e., the third direction, such as the Y direction shown in the figure) of the climbing device 100. Each lifter 20 includes a first frame 201, a second frame 202, and a connecting arm 203. The connecting arm 203 is movably connected between the first frame 201 and the second frame 202. The first frame 201 and the second frame 202 are arranged parallel to each other in the height direction of the climbing device 100, and the first frame 201 is slidably connected to the holding mechanism 1 in the length direction of the climbing device 100. In the height direction, the first frame 201 and the holding mechanism 1 are fixedly connected and relatively stationary.

[0069] The lifting action of the lifting mechanism 20 is achieved by the movement of the second frame 202 relative to the first frame 201 in the height direction: when the second frame 202 moves away from the first frame 201, the lifting mechanism 2 performs an extension lifting action; when the second frame 202 moves closer to the first frame 201, the lifting mechanism 2 performs a retraction lowering action. In this structural design, the connecting arm 203, as a key component for force transmission and motion conversion, is used to transmit and convert the motion generated by the drive unit, and ultimately effectively apply the force driving the second frame 202 to move relative to the first frame 201 to the second frame 202, thereby realizing the extension and retraction movement of the lifting mechanism 2 in the height direction. Through the transmission action of the connecting arm 203, the force can be efficiently and smoothly converted into the linear displacement of the second frame 202 along the height direction, thereby driving the entire lifting mechanism 2 to achieve stable and reliable lifting or lowering actions. Furthermore, the lifting devices 20 placed on both sides of the holding mechanism 1 work together to provide balanced support and lifting force for the cleaning equipment 500 in the width direction, significantly enhancing the overall stability and load capacity of the climbing device 100 during the movement of different heights.

[0070] Meanwhile, since the first frame 201 remains fixedly connected to the holding mechanism 1 in the height direction, it not only ensures the posture stability of the holding mechanism 1 and the cleaning equipment 500 during the lifting process, but also further enhances the reliability of the sliding connection structure, making the movement of the holding mechanism 1 along the length direction smoother and more precise. This design, while realizing the height adjustment function, optimizes the force distribution and motion coordination of the structure, thus better adapting to cleaning equipment 500s of different specifications and weights, providing effective and reliable assistance for the climbing device 100 to move in environments with height differences, such as stairs.

[0071] It should be further noted that the lifting mechanism 2 consists of two independent lifting units 20, which are detachably mounted on both sides of the holding mechanism 1. This allows for adaptation to cleaning equipment 500 with different installation sizes, weights, and types by replacing the holding mechanisms 1 with those of different sizes or structural forms, according to actual application needs. This design not only improves the system compatibility and scalability of the entire climbing device 100 but also significantly enhances the convenience of maintenance and replacement operations. When different cleaning tasks or equipment upgrades are required, configuration adjustments can be quickly completed by simply disassembling and replacing the corresponding holding mechanism 1 module, greatly enhancing the applicability and economy of the equipment.

[0072] In some embodiments of this application, the connecting arm 203 includes two support arms 2030, which are hinged between the first frame 201 and the second frame 202, so that the connecting arm 203 is used as a key component for force transmission and motion conversion in the first frame 201 and the second frame 202, thereby realizing the effect of telescopic movement of the lift 20 in the height direction.

[0073] In some embodiments, the same end of the two support arms 2030 is fixedly hinged to one of the first frame 201 and the second frame 202, and the other end of the two support arms 2030 is slidably hinged to the other of the first frame 201 and the second frame 202, respectively, to achieve a more stable and controllable lifting movement. Specifically, if the first ends of both support arms 2030 are fixedly hinged to the first frame 201, then the second ends of both support arms 2030 are slidably hinged to the second frame 202; or, if the first ends of both support arms 2030 are slidably hinged to the second frame 202, then the second ends of both support arms 2030 are fixedly hinged to the second frame 202. Taking the configuration where the first ends of the two support arms 2030 are fixedly hinged to the first frame 201 and the second ends are slidably hinged to the second frame 202 as an example, its structure can be further divided into two cases:

[0074] Firstly, when the two support arms 2030 are fixedly hinged to the ends of the first frame 201 at the same position, the first frame 201, the second frame 202, and the two support arms 2030 together form an isosceles triangle structure, with the two support arms 2030 serving as the "legs" of the triangle, and the first frame 201 and the second frame 202 corresponding to the "base" and "top" of the triangle, respectively. This structure provides a symmetrical and stable force transmission path during the lifting process of the elevator 20, helping the elevator 20 maintain stability during lifting.

[0075] Secondly, when the two support arms 2030 are fixedly hinged to the end points of the first frame 201 at intervals, the first frame 201, the second frame 202, and the two support arms 2030 together form an isosceles trapezoidal structure, with the two support arms 2030 serving as the "sleeves" of the trapezoid. This structure can adjust the lever arm ratio during the lifting process within a certain range, thereby optimizing the mechanical performance and movement trajectory of the elevator 20.

[0076] Therefore, according to the connecting arm 203 of this application, it not only realizes the effective motion conversion and force transmission between the first frame 201 and the second frame 202, but also further enhances the structural rigidity and motion stability of the lifting device 20 during the extension and retraction process through its geometric configuration, which is conducive to improving the control accuracy and reliability of the climbing device 100 when lifting or lowering the cleaning equipment 500.

[0077] Or like Figure 6 and Figure 7 As shown, in some other embodiments, the two support arms 2030 are hinged at the middle, and one or both ends of each support arm 2030 are respectively hinged to the first frame 201 and the second frame 202, and at least one end of each support arm 2030 is slidably connected to its corresponding first frame 201 or second frame 202 to improve the smoothness of the lifting movement of the elevator 20. Specifically, its structure can be further divided into two cases:

[0078] One of them is like Figure 6 As shown, two cross-hinged support arms 2030 are each connected at one end to either the first frame 201 or the second frame 202 via a sliding hinge. That is, both ends of each support arm 2030 can slide on the corresponding frame (i.e., the first frame 201 or the second frame 202). This design creates a symmetrical sliding linkage mechanism between the two support arms 2030. During the lifting and lowering movement of the lifter 20, the endpoints of the two support arms 2030 slide synchronously, making the lifting or lowering movement of the second frame 202 relative to the first frame 201 extremely smooth. The force transmission path is symmetrical and balanced, significantly reducing swaying during movement.

[0079] Secondly, as Figure 7As shown, a hybrid connection method is used in the two centrally hinged support arms 2030. One support arm 2030 has its first end connected to the first frame 201 via a fixed hinge (i.e., rotating but not sliding), while its second end is connected to the second frame 202 via a sliding hinge. The other support arm 2030 has its first end connected to the first frame 201 via a sliding hinge, while its second end is connected to the second frame 202 via a fixed hinge. This symmetrical design optimizes the stress distribution of the structure while ensuring motion functionality. The fixed hinge point provides a stable rotational fulcrum, while the sliding hinge point absorbs and converts motion. This configuration effectively reduces wear on the moving parts and achieves a greater lifting stroke within a compact space, enhancing the structural rigidity and durability of the elevator 20.

[0080] Additionally, it should be noted that: [the following is a combination of...] Figure 7 As shown, since the two support arms 2030 are respectively fixed hinged to their corresponding brackets, and both fixed hinge points are stable virtual rotation centers, the combined center of gravity of the entire climbing device 100 can always be concentrated in a preset position. This ensures the stability and reliability of the climbing device 100 during its operation. For example, see... Figure 7 As shown, in the length direction of the climbing device 100, these two fixed hinge points are located near the front end of the lifting mechanism 2, thereby forcing the overall center of gravity of the climbing device 100 to always be concentrated in the front area.

[0081] In addition, it should be noted that: Figure 6 and Figure 7 As shown, the two outriggers 2030 are hinged at the middle, meaning the hinge point of the two outriggers 2030 is located at the midpoint of the outriggers 2030. This design ensures that the hinge point of the connecting arm 203 is always precisely maintained at the center position of the first frame 201 and the second frame 202 in the height direction during the lifting process, forming a completely symmetrical force transmission system. This ensures that the force applied during the lifting process of the elevator 20 is completely symmetrically distributed along the height direction, completely eliminating the off-center load moment caused by unequal lever arm lengths, and ensuring that the second frame 202 always maintains pure vertical movement without any lateral offset. Secondly, the central hinge point evenly distributes the lifting load to the two outriggers 2030, keeping the connecting arm 203 in an optimal stress state. This not only significantly reduces the unit area stress of each kinematic pair and reduces wear, but also greatly improves the structural rigidity and load-bearing capacity of the entire elevator 20. Furthermore, this symmetrical design ensures that the lifting device 20 maintains consistent transmission characteristics at different height positions, guaranteeing high stability throughout the lifting process and greatly enhancing the reliability of the lifting mechanism 2.

[0082] See Figure 8 and Figure 9As shown, in some embodiments of this application, both the first frame 201 and the second frame 202 include a frame body 21 and a sliding assembly 22, with the sliding assembly 22 disposed on the frame body 21. The sliding assembly 22 includes a slide rail structure 221 and at least one slider 222. The slide rail structure 221 extends along the length of the frame (i.e., the first frame 201 and the second frame 202), and the slider 222 is slidably disposed on the slide rail structure 221. In the support arm 2030 of the connecting arm 203, the end that needs to achieve a sliding connection with the frame is hinged to the corresponding slider 222.

[0083] Specifically, the slide structure 221 can be constructed as a slide rail or a slide groove. A slide rail is a guide structure protruding from the surface of the frame, while a slide groove is a guide structure recessed into the surface of the frame; both provide a precise linear motion path for the slider 222. The slider 222 is mounted on the slide structure 221 and can slide smoothly along the length of the frame along the slide structure 221. The end of the support arm 2030 is connected to the slider 222 via a hinge shaft, allowing the end of the support arm 2030 to have rotational freedom while also being able to perform linear displacement along the slide structure 221 via the slider 222. Because the slide structure 221 provides high-precision guidance for the sliding of the slider 222, it ensures that the slider 222 and the hinged end of the support arm 2030 move along the extension direction of the slide structure 221, eliminating unintended offsets in other directions. This makes the movement trajectory of the second frame 202 relative to the first frame 201 more precise and stable during the extension and retraction of the lifting device 20, ultimately ensuring the stability of the cleaning equipment 500 during the lifting process.

[0084] In summary, by setting a sliding assembly 22 consisting of a slide rail structure 221 and a slider 222 on the first frame 201 and the second frame 202, not only are the sliding hinge function requirements of the support arm 2030 met, but the mechanical properties and motion accuracy of the lift 20 are further optimized, thereby improving the reliability of the climbing device 100.

[0085] In some embodiments of this application, one or both ends of the support arm 2030 are connected to the corresponding slider 222. Both the first frame 201 and the second frame 202 also include a synchronous transmission mechanism 23, which is drivenly connected between the sliders 222 located in the same frame, enabling the sliders 222 in the same frame to move synchronously. Specifically, the ends of the support arm 2030 that need to be slidably connected to the frame are hinged to the corresponding sliders 222. The synchronous transmission mechanism 23 is mounted on the frame body 21 and drivenly connected between all the sliders 222 located in the same frame. Through the forced transmission action of the synchronous transmission mechanism 23, all sliders 222 can maintain strict synchronization when moving along the slide structure 221, thereby ensuring that the same end of the two support arms 2030 can move simultaneously and equally, fundamentally avoiding the problem of the lift 20 jamming or uneven load caused by the delayed movement of a single slider 222. Furthermore, since the sliders 222 located in the same frame are all connected to the same synchronous transmission mechanism 23, the sliders 222 in the same frame can slide synchronously and can limit each other to maintain static stability in a static state. Thus, the lifting device 20 according to this application has better smoothness, synchronization and stability in a static state during the telescopic movement, ensuring that the cleaning equipment 500 always remains horizontal during the lifting process and can be reliably locked at any height position.

[0086] For example, see Figure 8 As shown, in some embodiments, the synchronous transmission mechanism 23 employs a rack and pinion drive, comprising two synchronous racks 231 and one synchronous gear 232. The two synchronous racks 231 are respectively arranged on both sides of the slide structure 221 in the height direction of the climbing device 100 (i.e., the height direction of the frame body 21, Z-direction), and each synchronous rack 231 extends along the length direction of the climbing device 100 (i.e., the length direction of the frame body 21, X-direction). The synchronous gear 232 is rotatably mounted on the frame body 21 via a shaft and meshes with both synchronous racks 231 simultaneously. Each slider 222 is fixedly connected to the corresponding synchronous rack 231 (e.g., by meshing or other connection methods).

[0087] Specifically, when an external force drives any one component (synchronous rack 231 or synchronous gear 232) or a slider 222 in the synchronous transmission mechanism 23 to move, the other components not directly driven will move synchronously. For example, when an external force drives the synchronous gear 232 to rotate, the synchronous gear 232 drives the two synchronous racks 231 connected to it to move synchronously in opposite directions and translate by equal amounts in the length direction, and synchronously drives the corresponding slider 222 to move synchronously in opposite directions and translate by equal amounts. Most importantly, at rest, since the slider 222 is fixedly connected to the synchronous rack 231, and the synchronous gear 232 is meshed between the two synchronous racks 231, when the synchronous gear 232 is stationary, it can effectively lock the synchronous racks 231, preventing the two synchronous racks 231 from translating, thereby preventing the slider 222 from sliding on the slide structure 221, thus keeping the entire lifting mechanism 2 stably at the current height position, achieving a reliable locking effect, and ensuring that the holding mechanism 1 and the cleaning equipment 500 it carries can stay safely and stably at the required height.

[0088] Or refer to Figure 9 As shown, in some other embodiments, the synchronous transmission mechanism 23 employs a synchronous belt 234 transmission method. The synchronous transmission mechanism 23 includes two synchronous pulleys 233 and a closed-loop synchronous belt 234. The two synchronous pulleys 233 are respectively mounted at both ends of the slide structure 221 along the length direction (X-direction) of the frame body 21. The synchronous belt 234 is tightly fitted onto the two synchronous pulleys 233. Two sliders 222 are respectively fixedly connected to both sides of the synchronous belt 234 along the height direction (Z-direction) of the frame body 21.

[0089] Specifically, as the synchronous belt 234 rotates around its circumference, it drives the two sliders 222 connected to its two sides to move simultaneously, in opposite directions, and by equal amounts. Similarly, in a stationary state, because the sliders 222 and the synchronous belt 234 are fixedly connected, the entire system consisting of the synchronous transmission mechanism 23 and the sliders 222 is in a self-locking or static equilibrium state. This prevents the sliders 222 from moving freely on the slide rail, thus reliably maintaining (locking) the position of the lifting mechanism 2 and ensuring operational safety and stability.

[0090] In summary, by incorporating a synchronous transmission mechanism 23 in the first frame 201 and the second frame 202 of the lifting device 20, not only is precise synchronization of the moving parts of the lifting device 20 ensured during lifting operations, eliminating off-center loading, swaying, and wear caused by asymmetrical motion, but also, through an effective locking function in a static state, it ensures that the holding mechanism 1 and the cleaning equipment 500 can remain safely and stably at any target height. This significantly improves the reliability, safety, and overall performance of the climbing device 100 under harsh conditions such as climbing stairs.

[0091] Combination Figure 3 and Figure 8 As shown, and as Figure 9 As shown, in some embodiments of this application, the lifting device 20 further includes a lifting drive 204, which is configured to drive the connecting arm 203 to move, causing the first frame 201 and the second frame 202 to extend and retract, so that the first frame 201 and the second frame 202 move relative to each other in the height direction of the climbing device 100. Specifically, the lifting drive 204 is fixedly installed on the frame (i.e., the first frame 201 or the second frame 202) of the lifting device 20, and the power output end of the lifting drive 204 is connected to the transmission system of the connecting arm 203. The lifting drive 204 is configured to provide initial power to drive the connecting arm 203 to move (e.g., drive the support arm 2030 to rotate about the hinge point or cause the slider 222 to move along the slide rail), so as to realize the controllable movement of the second frame 202 relative to the first frame 201 in the height direction, thereby completing the extension lifting or retraction lowering action of the lifting mechanism 2.

[0092] For example, the lifting drive 204 can preferably be configured as a drive motor. For instance, in conjunction with... Figure 3 and Figure 8 As shown, in some embodiments of this application, the drive motor can be directly connected to the synchronous gear 232 in the synchronous transmission mechanism 23. After the drive motor starts, it directly drives the synchronous gear 232 to rotate forward or reverse. The rotation of the synchronous gear 232 meshes with and drives the synchronous racks 231 on both sides to perform synchronous reverse linear motion, thereby driving the slider 222 fixed to the racks to move. The movement of the slider 222 further forces the support arm 2030 hinged to it to rotate, ultimately converting the rotational motion into precise linear lifting and lowering motion of the second frame 202.

[0093] Or refer to Figure 9 As shown, in some embodiments of this application, the drive motor can be directly coaxially connected to at least one synchronous pulley 233 in the synchronous transmission mechanism 23. After the drive motor starts, it directly drives the synchronous pulley 233 to rotate. The rotation of the synchronous pulley 233 will drive the closed-loop synchronous belt 234 to move, and the synchronous belt 234 will pull the sliders 222 fixed on both sides of it to perform synchronous and opposite linear motion. Similarly, the movement of the sliders 222 will force the support arm 2030 to rotate, thereby realizing the lifting and lowering of the second frame 202.

[0094] In summary, the lifting device 20 according to this application includes a lifting drive motor 204, realizing the electrification and automation control of the lifting process of the lifting device 20. This makes the start-up, stopping, and speed control of the lifting action of the lifting device 20 more precise and reliable, without the need for manual intervention, greatly improving the intelligence level of the climbing device 100 and the user experience.

[0095] See Figure 3 and Figure 4 ,as well as Figures 8 to 11 As shown, in some embodiments of this application, the climbing device 100 further includes a translation drive mechanism 3, which is configured to drive the holding mechanism 1 and the lifting mechanism 2 to slide relative to each other in the length direction of the climbing device 100.

[0096] In some embodiments, the translation drive mechanism 3 includes two first translation actuators, both of which are disposed on the holding mechanism 1, and each first translation actuator has a first translation gear. Both first frames 201 have a first translation rack extending along the length direction of the climbing device 100, and each first translation gear meshes with a corresponding first translation rack. Specifically, the translation drive mechanism 3 includes two first translation actuators. Both first translation actuators are fixedly disposed on the holding mechanism 1. Each first translation actuator has a first translation gear. Correspondingly, each of the first frames 201 of the two lifters 20 is provided with a first translation rack extending along the length direction of the climbing device 100. Each first translation gear meshes with a first translation rack located on the same side of the first frame 201.

[0097] When it is necessary to move the holding mechanism 1 relative to the lifting mechanism 2, the first translation driver is activated, driving its first translation gear to rotate. Since the first translation gear meshes with the first translation rack fixed to the first frame 201, and the first translation driver itself is fixed to the holding mechanism 1, the rotational motion of the first translation gear, under the reaction of the first translation rack, is converted into a smooth and precise linear motion of the entire holding mechanism 1 (together with the cleaning equipment 500 on it) relative to the first frame 201 and the lifting mechanism 2 in the length direction.

[0098] The first translational actuator is directly mounted on the holding mechanism 1, and the first translational gear directly meshes with the first translational rack fixed on the lifting mechanism 2. This results in a compact structure with a direct and efficient force transmission path, eliminating the need for additional complex transmission chains. Furthermore, by controlling the rotation direction of the first translational gear driven by the first translational actuator, bidirectional forward or backward movement of the holding mechanism 1 relative to the lifting mechanism 2 can be easily achieved, adapting to the different horizontal movement requirements of the climbing device 100 during climbing and descent.

[0099] Furthermore, the two first translational actuators are placed on both sides of the holding mechanism 1 and drive the gear rack pairs on both sides synchronously, ensuring that the holding mechanism 1 is subjected to balanced force during movement, avoiding jamming or tilting, and maintaining the posture stability of the assembly of the cleaning equipment 500 and the climbing device 100.

[0100] Alternatively, in some embodiments, the translation drive mechanism 3 includes at least one second translation driver, which is disposed on the first frame 201 and has a second translation gear. The holding mechanism 1 has at least one second translation rack extending along the length direction of the climbing device 100, and the second translation gear is meshed with the second translation rack. Specifically, when the translation drive mechanism 3 includes one second translation driver, the holding mechanism 1 is provided with a corresponding second translation rack, and the second translation gear of the second translation driver is meshed with this second translation rack. When the translation drive mechanism 3 includes two second translation drivers, the holding mechanism 1 is provided with two corresponding second translation racks, and the second translation gear of each second translation driver is meshed with each second translation rack in a one-to-one correspondence. Preferably, the two second translation drivers and the two second translation racks are symmetrically arranged on both sides of the holding mechanism 1 in the width direction (i.e., the third direction, such as the Y direction shown in the figure) of the climbing device 100.

[0101] When it is necessary to move the holding mechanism 1 relative to the lifting mechanism 2, the second translation driver, fixedly mounted on the first frame 201, is activated, driving its second translation gear to rotate. Since the second translation gear meshes with the second translation rack fixed to the holding mechanism 1, and the second translation driver itself is fixed to the first frame 201, the rotational motion of the second translation gear, under the reaction force of the second translation rack, is converted into a smooth and precise linear motion of the entire holding mechanism 1 (along with the cleaning device 500 on it) relative to the first frame 201 and the lifting mechanism 2 in the length direction. In embodiments with two second translation drivers and second translation racks, the two drivers can operate synchronously, ensuring smooth movement of the holding mechanism 1 without deviation or jamming.

[0102] Or, see Figure 3 and Figure 4 ,as well as Figures 8 to 11 As shown, in some embodiments, the translation drive mechanism 3 includes a third translation driver 31 and a translation transmission shaft 32. Both the third translation driver 31 and the translation transmission shaft 32 are disposed on the holding mechanism 1. The third translation driver 31 drives the translation transmission shaft 32 to rotate, and both ends of the translation transmission shaft 32 have a third translation gear 320. Both first frames 201 have a third translation rack 2010 extending along the length direction of the climbing device 100. The translation transmission shaft 32 extends along the width direction of the climbing device 100, so that the third translation gears 320 at both ends of the translation transmission shaft 32 are respectively engaged with the corresponding third translation rack 2010.

[0103] When the holding mechanism 1 needs to move relative to the lifting mechanism 2, the third translation driver 31 fixed to the holding mechanism 1 is activated, driving the translation transmission shaft 32 to rotate, which in turn drives the third translation gear 320 fixed at both ends of the shaft to rotate synchronously. Since the third translation gear 320 meshes with the third translation rack 2010 fixed to the left and right first frames 201 respectively, and the third translation driver 31 and the translation transmission shaft 32 are both fixed to the holding mechanism 1, the rotational motion of the gear, under the reaction of the rack, is converted into a smooth, precise and synchronous linear motion of the entire holding mechanism 1 (along with the cleaning equipment 500 on it and the drive components installed thereon) relative to the two first frames 201 and the lifting mechanism 2 in the length direction.

[0104] In summary, according to the translation drive mechanism 3 of this application, the translation drive mechanism 3 can actively, accurately, and synchronously drive the relative linear motion between the holding mechanism 1 and the lifting mechanism 2, realizing the complete automation of the horizontal movement of the climbing device 100. The translation drive mechanism 3 not only ensures the smoothness and precise posture control of the cleaning equipment 500 during step transitions, and has strong load adaptability and bidirectional movement capability, but also possesses high reliability and wide equipment compatibility due to its diversified integrated design.

[0105] See Figure 4 , Figure 10 As shown, in some embodiments of this application, the translation drive mechanism 3 further includes a transmission component 33, which is connected between the third translation driver 31 and the translation drive shaft 32 so that the third translation driver 31 drives the translation drive shaft 32 to rotate.

[0106] For example, see Figure 4 As shown, in some embodiments, the transmission assembly 33 includes a first transmission gear 331 and a second transmission gear 332. The first transmission gear 331 is located at the output end of the third translation driver 31 and is directly driven to rotate by the third translation driver 31. The second transmission gear 332 is fixedly mounted on the translation transmission shaft 32 and meshes with the first transmission gear 331. When the third translation driver 31 is started, the output shaft of the third translation driver 31 drives the first transmission gear 331 to rotate, and the first transmission gear 331 then drives the meshing second transmission gear 332 to rotate, thereby transmitting power to the translation transmission shaft 32, and finally driving the third translation gears 320 at both ends of the translation transmission shaft 32 to rotate synchronously. By setting the transmission assembly 33, the spatial layout and speed-torque matching requirements between the output shaft of the third translation driver 31 and the translation transmission shaft 32 can be adapted, achieving efficient, smooth and reliable power transmission.

[0107] It should be further explained that by setting the gear ratio (i.e., gear ratio) between the first transmission gear 331 and the second transmission gear 332, the transmission component 33 can achieve the effect of speed reduction and torque increase, that is, convert the high-speed, low-torque motion output by the third translation driver 31 into the low-speed, high-torque motion required by the translation transmission shaft 32, thereby providing a stronger driving force for the translation of the holding mechanism 1 and improving its motion control characteristics.

[0108] Or, see Figure 10 As shown, in some embodiments of this application, the transmission assembly 33 includes a first transmission pulley 333, a second transmission pulley 334, and a transmission belt 335. The first transmission pulley 333 is disposed at the output end of the third translation driver 31 and is directly driven to rotate by the third translation driver 31. The second transmission pulley 334 is fixedly disposed on the translation transmission shaft 32. The transmission belt 335 is sleeved between the first transmission pulley 333 and the second transmission pulley 334, thereby forming a belt drive connection. When the third translation driver 31 is started, the output shaft of the third translation driver 31 drives the first transmission pulley 333 to rotate, and the first transmission pulley 333 drives the second transmission pulley 334 to rotate through the transmission belt 335, thereby transmitting power to the translation transmission shaft 32, and finally driving the third translation gears 320 at both ends of the translation transmission shaft 32 to rotate synchronously.

[0109] It should be further explained that by setting the diameter ratio between the first transmission pulley 333 and the second transmission pulley 334, the transmission component 33 can achieve a specific speed reduction and torque increase effect, that is, convert the speed and torque output by the third translation driver 31 to adapt to the load requirements of the translation transmission shaft 32. In addition, the belt drive method also has the characteristics of buffering and vibration absorption, smooth operation, and low noise.

[0110] See Figure 11 As shown, in some embodiments of this application, the third translation driver 31 is configured as a dual-axis drive motor. The third translation driver 31 has two output shafts 310, and the translation transmission shaft 32 includes two translation transmission half-shafts 321, which are respectively connected to the two output shafts 310. The output shafts 310 and the translation transmission half-shafts 321 of the third translation driver 31 can be directly connected or indirectly connected through transmission components. For example, see... Figure 11 As shown, in some embodiments, the output shaft 310 of the third translational actuator 31 is connected and fixed to the translational drive half-shaft 321 via a connecting sleeve 336. Specifically, the ends of the output shaft 310 and the translational drive half-shaft 321 both extend into the connecting sleeve 336 and are fixed circumferentially and axially by means of key connection, set screws, or interference fit, so that the torque of the output shaft 310 can be effectively transmitted to the translational drive half-shaft 321.

[0111] By using a connecting sleeve 336 for connection, an adjustable connection distance can be provided between the output shaft 310 of the third translation driver 31 and the translation transmission half shaft 321. This design can effectively adjust the overall length between the third translation driver 31 and the transmission components on both sides, thereby flexibly adapting to the installation requirements of the holding mechanism 1 with different widths, and enhancing the versatility of components and the adaptability of the mechanism.

[0112] When the holding mechanism 1 needs to move, the dual-axis driven third translation driver 31 synchronously drives its two output shafts 310 to rotate. The output shafts 310 transmit power to the left and right translation transmission half-shafts 321 respectively through the connecting sleeve 336, thereby driving the third translation gears 320 fixed to the ends of each translation transmission half-shaft 321 to rotate synchronously. Since the third translation gear 320 meshes with the third translation rack 2010 fixed to the first frame 201, the rotational motion of the gear, under the reaction of the rack, is ultimately converted into a smooth and synchronous linear motion of the entire holding mechanism 1 relative to the lifting mechanism 2 in the length direction. The third translation driver 31 is constructed as a dual-axis drive motor to further ensure the synchronicity of the transmission sides and the balance of the driving force output.

[0113] See Figure 1 and Figure 2 As shown, the cleaning component 1000 according to this application includes a climbing device 100 and a cleaning device 500. The cleaning device 500 is adapted to be held by the holding mechanism 1 of the climbing device 100. Based on the holding mechanism 1 and the lifting mechanism 2 of the climbing device 100, the cleaning device 500 can be displaced in the length and height directions of the climbing device 100. Specifically, the external dimensions of the cleaning device 500 are adapted to the holding space 10 within the holding mechanism 1, so that the cleaning device 500 can be moved into the holding space 10 through the opening 101, and a reliable connection with the climbing device 100 is achieved through the fixed connection provided by the holding mechanism 1, thereby forming an integrated cleaning component 1000 unit.

[0114] In this cleaning component 1000, the climbing device 100 serves as a mobile auxiliary platform for the cleaning equipment 500. The sliding connection and coordinated movement between its lifting mechanism 2 and holding mechanism 1 jointly undertake the movement requirements of the cleaning equipment 500 in the height direction (Z direction) and length direction (X direction). The cleaning equipment 500 itself does not need to have any additional structures specifically for climbing or movement in a specific direction, thus maintaining its design independence and functionality.

[0115] When the cleaning equipment 500 needs to perform routine cleaning tasks on flat ground, it can be separated from the climbing device 100 and operate flexibly as an independent unit, avoiding additional load and size constraints. When encountering structures with height differences such as stairs or thresholds, the cleaning equipment 500 can be placed into the holding mechanism 1 and fixed, and the climbing device 100 can be used to stably and efficiently complete obstacle climbing or descending actions by means of its lifting and lateral movement functions.

[0116] The design of this cleaning component 1000 effectively expands the application scenarios and working range of the cleaning equipment 500, improves the utilization rate and user convenience of the cleaning equipment 500, and at the same time minimizes the restrictions and modifications to the design of the cleaning equipment 500 itself, thus having good versatility and economy.

[0117] 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.

[0118] 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.
