[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings of this invention are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0044] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0045] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0046] See appendix Figures 1 to 9 This utility model proposes an intelligent ladder, including a ladder frame 1, a pressure sensor 2, and an early warning module 3. The ladder frame 1 has ladder feet 11 at its bottom, and the pressure sensor 2 is installed at the ladder feet 11. The early warning module 3 is installed on the ladder frame 1 and electrically connected to the pressure sensor 2. Therefore, the early warning module 3 can determine the load condition of the ladder frame 1 through the detection result of the pressure sensor 2 and issue an early warning to the user based on the load condition of the ladder frame 1.

[0047] Among them, as attached Figures 1 to 4As shown, the ladder frame 1 consists of several rods 12 and several steps 13. The rods 12 include at least four support rods 121, with at least two support rods 121 forming the main frame 14 and at least two additional support rods 121 forming the secondary frame 15. Several steps 13 are mounted on the main frame 14, and the secondary frame 15 is rotatably mounted on the main frame 14. Rotation of the secondary frame 15 allows the frame to be folded or unfolded. The bottom of each support rod 121 forms a ladder foot 11, preferably with a pressure sensor 2 installed at each ladder foot 11. Of course, in other embodiments, pressure sensors 2 may be installed at only one or two ladder feet 11.

[0048] The ladder includes several poles 12, each with a handrail 122 connected to two support poles 121 forming the main frame 14. The handrail 122 is located at the top of the main frame 14, giving it an arch shape. Users can use the handrail 122 to move the ladder or to stabilize themselves while climbing it.

[0049] The plurality of rods 12 also includes at least one stabilizing rod 123, which is connected to the two support rods 121 constituting the subframe 15 and is used to strengthen the structure of the subframe 15. For example, a horizontal stabilizing rod 123 may be provided, or two cross-distributed stabilizing rods 123 may be provided. Alternatively, in addition to providing two horizontal stabilizing rods 123 connecting the two support rods 121 of the subframe 15, two additional stabilizing rods 123 may be provided between the two horizontal stabilizing rods 123 in a cross-distributed “X” shape to further strengthen the structure of the subframe 15.

[0050] Furthermore, several pedals 13 can be linked together when the ladder frame 1 is folded or unfolded. Specifically, each pedal 13 is rotatably mounted on a support rod 121 constituting the main frame 14. The rods 121 also include connecting rods 124, which are rotatably connected to each pedal 13 and are parallel to the support rods 121 constituting the main frame 14. Therefore, rotating any one pedal 13 can cause all the other pedals 13 to rotate together. When the ladder frame 1 is unfolded, a slot 131 can be made on the topmost pedal 13 to fix its position, and a positioning rod 125 is installed on the sub-frame 15. When the positioning rod 125 abuts in the slot 131, it indicates that the pedal 13 is in a horizontal state, meaning the ladder frame 1 is fully unfolded. Of course, the positioning rod 125 can also be used simultaneously as a stabilizing rod 123.

[0051] Furthermore, to make the load-bearing structure of the pedal 13 more stable, the several rods 12 may include multiple crossbars 126. The multiple crossbars 126 are horizontally connected to the two support rods 121 that constitute the main frame 14. The pedal 13 is hooked on the crossbars 126 and can rotate around the crossbars. Then, an anti-detachment mechanism is installed on the pedal 13 to prevent the pedal 13 from detaching from the crossbars 126.

[0052] Furthermore, to ensure that the folding and unfolding of the sub-frame 15 is linked to the rotation of the pedal 13, i.e., the entire ladder frame 1 can be folded or unfolded by rotating one pedal 13, in a preferred embodiment, a hook 132 is rotatably installed on the topmost pedal 13. The hook 132 is hooked onto the positioning rod 125, and the connection point between the hook 132 and the pedal 13 is close to the main frame 14. The hook 132 is used to limit the position between the pedal 13 and the positioning rod 125. When the pedal 13 is rotated and unfolded, the hook 132 can drive the positioning rod 125 to move away from the main frame 14, thus unfolding the sub-frame 15; when the pedal 13 is rotated and folded, the hook 132 can drive the positioning rod 125 to move closer to the main frame 14, thus folding the sub-frame 15.

[0053] In some embodiments, see Appendix Figure 1 and Figure 5 The early warning module 3 includes a mounting shell 31 and at least one functional unit 32. The mounting shell 31 is mounted on the ladder frame 1, and at least one functional unit 32 is mounted on the mounting shell 31. The functional unit 32 is used to provide early warning information.

[0054] The mounting shell 31 can be installed on any of the aforementioned rods 12 or pedals 13. For example, the mounting shell 31 can be installed on the support rod 121 that constitutes the main frame 14, or on the pedal 13, or on the handrail 122. The mounting shell 31 can adopt a fixed installation structure or a detachable installation structure. Fixed installation structures include bolt fixing and welding fixing, while detachable installation structures include magnetic attraction, snap-fit, and elastic clamping.

[0055] For ease of description, the following description is based on an embodiment where the mounting housing 31 is mounted on the handrail 122, as shown in the attached figure. Figure 1 As shown.

[0056] Preferably, the height of the ladder frame 1 is set to 1.0 meter to 3.0 meter, so that when the user climbs the smart ladder, it is easier to notice the warning information issued by the functional unit 32.

[0057] Specifically, see the appendix. Figures 5 to 7The mounting housing 31 includes a first housing 311 and a second housing 312, which are together clamped and fixed to the handrail 122. At least one functional unit 32 is mounted on at least one of the first housing 311 or the second housing 312. In some embodiments, the first housing 311 and the second housing 312 are connected to form a cylindrical mounting housing 31, so that the mounting housing 31 is connected to the handrail 122 in a sleeve manner.

[0058] Furthermore, at least one through mounting hole 101 is provided on the handrail 122, and the mounting shell 31 also includes at least one mounting part 313, which passes through the mounting hole 101, so that the first shell 311 and the second shell 312 are fixedly connected through the mounting part 313.

[0059] Specifically, the mounting part 313 includes a first connecting post 3131, a second connecting post 3132, and a locking member 3133. The first connecting post 3131 is integrally formed on the first housing 311, and the second connecting post 3132 is integrally formed on the second housing 312. The first connecting post 3131 and the second connecting post 3132 are inserted from both ends of the mounting hole 101, respectively. The locking member 3133 is a bolt, which passes through the second connecting post 3132 and is threaded onto the first connecting post 3131. Alternatively, the bolt can pass through the first connecting post 3131 and be threaded onto the second connecting post 3132. Therefore, the mounting part 313 can be used to fix the mounting housing 31 onto the handrail 122 and prevent the mounting housing 31 from rotating relative to the handrail 122.

[0060] In some embodiments, the first shell 311 includes a first main body portion 3111 and a first extension portion 3112, and the second shell 312 includes a second main body portion 3121 and a second extension portion 3122. The first main body portion 3111 and the second main body portion 3121 are connected by at least one mounting portion 313, and the first extension portion 3112 and the second extension portion 3122 are connected by at least one mounting portion 313. At least one functional unit 32 is disposed on the first main body portion 3111 or the second main body portion 3121. The warning module 3 also includes a mounting sleeve 33, which surrounds the first extension portion 3112 and the second extension portion 3122. The mounting sleeve 33 is made of a soft material, such as rubber or sponge, to facilitate the user's gripping of the handrail 122. At the same time, the mounting sleeve 33 can also help fix the first shell 311 and the second shell 312, that is, prevent the first shell 311 and the second shell 312 from detaching from each other.

[0061] Understandable, as shown in the attached document. Figure 5As shown, two first extensions 3112 can be provided, and they are respectively located on both sides of the first main body 3111; two second extensions 3122 can also be provided, and they are respectively located on both sides of the second main body 3121. Four mounting holes 101 are provided, and the mounting shell 31 includes four mounting portions 313, of which two first connecting posts 3131 are respectively provided on the two first extensions 3112, and the other two first connecting posts 3131 are both provided on the first main body 3111; correspondingly, two second connecting posts 3132 are respectively provided on the two second extensions 3122, and the other two second connecting posts 3132 are both provided on the second main body 3121.

[0062] Of course, in other embodiments, the first shell 311 and the second shell 312 may also be fixed to the handrail 122 without bolt locking. Specifically, in this other embodiment, the mounting part 313 also includes a first connecting post 3131, a second connecting post 3132, and a locking member 3133, but in this case, the locking member 3133 is a magnet, and the first connecting post 3131 and the second connecting post 3132 are connected by magnetic attraction. In this case, the function of the first connecting post 3131 and the second connecting post 3132 is to prevent the mounting shell 31 from rotating relative to the handrail 122. A mounting sleeve 33 is then provided, which is used to loop around the first extension 3112 and the second extension 3122 to prevent the first shell 311 and the second shell 312 from detaching from each other, thereby fixing the mounting shell 31 to the handrail 122. This other embodiment is not shown in the accompanying drawings.

[0063] In some embodiments, see Appendix Figure 4 , 7 In embodiment 8, a groove is formed on the outer surface of the mounting shell 31, and a protruding buffer portion 314 is provided in the groove. The buffer portion 314 is flexibly provided, for example, the buffer portion 314 is provided on the outer surface of the second shell 312; furthermore, at least a portion of the buffer portion 314 is bonded to the groove to prevent the buffer portion 314 from falling off. When the ladder frame 1 is folded for storage, the handrail 122 can be leaned against the wall. At this time, the buffer portion 314 abuts against the wall, which can protect the mounting shell 31 and its functional units 32 from damage. In some other embodiments, the groove may not be provided on the mounting shell 31, and the flexibly provided buffer portion 314 can be fixed to the outer surface of the mounting shell 31 by adhesive.

[0064] In some embodiments, see Appendix Figures 6 to 8The early warning module 3 also includes a control board 34, a power supply unit 35, and a charging device 36. The control board 34 may be a PCBL circuit board, the power supply unit 35 may be a battery, and the charging device 36 may be an electrical connection interface. The control board 34, the power supply unit 35, and the charging device 36 are all housed within the mounting housing 31. For example, in some embodiments, the control board 34 is bolted to the first housing 311, and the power supply unit 35 and the charging device 36 are bolted to the second housing 312.

[0065] The ladder frame 1 has a power outlet 102, and the power supply device 35 is located inside the power outlet 102 to prevent the power supply device 35 from being exposed to the outside. The control board 34 is electrically connected to the power supply device 35, the charging device 36, and the pressure sensor 2. At least one functional unit 32 is mounted on the control board 34, preferably all functional units 32 are integrated on the control board 34. The power supply device 35 enables the smart ladder to have a built-in power supply, improving the portability of the smart ladder, while the charging device 36 can be connected to an external power source to charge the power supply device 35.

[0066] Furthermore, the control board 34 is provided with a number of connection terminals 341, the number of which is the same as the sum of the number of power supply devices 35, charging devices 36, and pressure sensors 2. That is, each power supply device 35, each charging device 36, and each pressure sensor 2 is electrically connected to a corresponding connection terminal 341. The purpose of this arrangement is mainly to facilitate the maintenance and replacement of power supply devices 35, charging devices 36, and pressure sensors 2.

[0067] It is understandable that the aforementioned mounting holes 101 and power holes 102 are actually opened on the rod 12 on which the mounting shell 31 is installed or on the pedal 13 on which it is installed, and are not limited to being opened only on the handrail 122.

[0068] In some embodiments, see Appendix Figure 3 and 8 The rod body 12 is hollow, forming a wire passage 120. The warning module 3 is electrically connected to the pressure sensor 2 via a wire 4, and the wire 4 is at least partially housed within the wire passage 120. Correspondingly, wire passages 120 are formed within both the support rod 121 and the handrail 122, and the wire passages 120 extend through to the foot of the ladder 11. For example, see attached... Figure 2As shown, the main frame 14 has two ladder legs 11, and the sub-frame 15 also has two ladder legs 11, with a pressure sensor 2 installed at each ladder leg 11. At this point, the wire 4, which electrically connects the pressure sensor 2 on the sub-frame 15 to the warning module 3, is only partially exposed at the connection between the main frame 14 and the sub-frame 15. This design prevents damage to the wire 4 during repeated unfolding and folding of the sub-frame 15 and the main frame 14. Furthermore, a protective sleeve can be installed at the connection between the main frame 14 and the sub-frame 15, covering the outer periphery of the exposed portion of the wire 4 to prevent damage to the exposed portion of the wire 4.

[0069] In the preferred embodiment, as shown in the appendix Figure 9 As shown, the entire conductor 4 is housed within the wire passage 120. Compared to the previous embodiment, by improving the rotation structure of the main frame 14 and the sub-frame 15 and adopting a concentric sleeve connection, the wire passage 120 in the sub-frame 15 can be connected to the wire passage 120 in the main frame 14. Therefore, the entire conductor 4 can be housed within the wire passage 120, resulting in a more aesthetically pleasing and durable design.

[0070] In addition, both the mounting hole 101 and the power hole 102 are connected to the wiring channel 120, which means that the power supply device 35 is stored in the space of the wiring channel 120, so that the volume of the mounting shell 31 does not need to be increased.

[0071] In some embodiments, at least one functional unit 32 includes at least one of a display unit 321, a buzzer unit 322, a light-emitting unit 323, a voice unit 324, and a vibration unit 325. The warning function of the functional unit 32 may specifically be a change in the numbers displayed by the display unit 321, a change in the sound of the buzzer unit 322, a change in the light of the light-emitting unit 323, a voice prompt from the voice unit 324, or a vibration change from the vibration unit 325.

[0072] A viewing window 315 is provided on the mounting housing 31. For example, in some embodiments, the viewing window 315 is located on the first housing 311. The display unit 321 can be a digital display screen, which is located within the viewing window 315. The digital display screen can present the load-bearing information of the ladder frame 1 to the user in the form of a digital image. Of course, the display unit 321 can also display other information, such as time, temperature, humidity, etc.

[0073] The buzzer does not operate when the load-bearing capacity of the ladder frame 1 is within a safe range. Different buzzer sounds can be set for two different situations: when the load-bearing capacity of the ladder frame 1 approaches or exceeds a preset warning value. It also issues an alarm when the load-bearing capacity of the ladder frame 1 exceeds the preset warning value.

[0074] Similarly, the light-emitting unit 323 does not emit light when the load-bearing capacity of the ladder frame 1 is within a safe range. Different lights can be set for the two situations where the load-bearing capacity of the ladder frame 1 is close to the preset warning value and exceeds the preset warning value, so as to remind the user to pay attention to safety in real time.

[0075] The voice unit 324 can set different voice prompts for two situations: when the load-bearing capacity of the ladder frame 1 is close to the preset warning value and when it exceeds the preset warning value.

[0076] The vibration unit 325 can be integrated into the control board 34, mounted on the inner surface of the mounting housing 31, or mounted on the handrail 122. If the vibration unit 325 is mounted on the inner surface of the mounting housing 31 or on the handrail 122, an additional connection terminal 341 can be added to the control board 34 for electrical connection between the vibration unit 325 and the control board 34. The vibration unit 325 can be set with different vibration alerts for two different situations: when the load on the ladder frame 1 is close to or exceeds a preset warning value.

[0077] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this utility model specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of this utility model.
