[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of the present invention; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of the present invention or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0039] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0040] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0041] See attached Figures 1 to 8 The utility model provides an intelligent ladder, comprising a ladder frame 1, a pressure sensor 2 and a display module 3. The pressure sensor 2 detects the load condition of the ladder frame 1, and the display module 3 presents the load condition to the user.

[0042] Specifically, the ladder frame 1 is used for users to climb, and there is at least one pressure sensor 2 , which is installed at the bottom of the ladder frame 1 , and the pressure sensor 2 is used to detect the gravity change of the ladder frame 1 .

[0043] In this embodiment, the display module 3 is mounted on the ladder frame 1, the display module 3 has a display screen, the display module 3 is electrically connected to the pressure sensor 2 via a wire 5, and a battery is provided on the display module 3. In this embodiment, the display module 3 is integrated on the ladder frame 1 to prevent the user from missing the display module 3.

[0044] In other embodiments, the display module 3 can be arranged completely independently of the ladder frame 1, and both the display module 3 and the pressure sensor 2 are provided with built-in batteries, and the display module 3 and the pressure sensor 2 are connected by wireless signals, such as Bluetooth connection.

[0045] In addition, the intelligent ladder also has an information processing unit, which is used to process the information obtained by the pressure sensor 2. The information processing unit can be integrated on the pressure sensor 2 or set on the ladder frame 1 or on the display module 3. Fig. 9 As shown in , the information processing unit is arranged on the display module 3 .

[0046] Specifically, since a pressure sensor 2 is installed at the bottom of the ladder frame 1, the pressure sensor 2 is used to detect the gravity change of the ladder frame 1, that is, to detect the load condition of the ladder frame 1. The pressure sensor 2 transmits the obtained load data to the display module 3, and the display module 3 presents the load data to the user for observation, so that the user can confirm the status of the ladder frame 1 in real time.

[0047] In this embodiment, the pressure sensor 2 is specifically a resistance strain sensor.

[0048] In a preferred embodiment, as shown in the attached Figure 2 As shown in , the intelligent ladder also includes at least one force-bearing member 4, which is installed at the bottom of the ladder frame 1. The force-bearing member 4 is used to contact the ground. The force-bearing member 4 can be elastically deformed, and at least one force-bearing member 4 is against the aforementioned at least one pressure sensor 2. With the force-bearing member 4 supported on the ground, when the ladder frame 1 is loaded, the force-bearing member 4 will deform and squeeze the pressure sensor 2, and the pressure sensor 2 will obtain the load data according to the squeezing force. In other embodiments, a slidable telescopic rod can be set at the bottom of the ladder frame 1, and the pressure sensor 2 can be set at the top of the telescopic rod. When the telescopic rod is against the ground, the telescopic rod squeezes the pressure sensor 2.

[0049] Regarding the specific arrangement structure of the force bearing member 4, in a preferred embodiment, as shown in the attached Figure 3 , 4 As shown in , 5, the force-bearing member 4 includes a contact member 41 and a bearing column 42. The contact member 41 is installed at the bottom of the ladder frame 1. The contact member 41 is used to contact the ground. The contact member 41 can be elastically deformed. The bearing column 42 is vertically inserted in the contact member 41. The bearing column 42 is against the bottom surface of the pressure sensor 2. The bearing column 42 can rise and fall with the elastic deformation of the contact member 41. The degree of fluctuation of the bearing column 42 corresponds to the pressure applied to the pressure sensor 2. A contact boss 412 is provided at the bottom of the contact member 41. The bottom surface of the contact boss 412 is designed in an arc shape, so that the center of the contact boss 412 is in contact with the ground, and the bearing column 42 extends and distributes in the contact boss 412. When the contact boss 412 is against the ground, the load of the ladder frame 1 will drive the contact boss 412 to move toward the ground, but due to the reaction force of the ground on the contact boss 412, the center position of the contact boss 412 will be squeezed upward and elastically deformed, so that the bearing column 42 is pushed upward relative to the contact member 41, that is, the bearing column 42 pushes the pressure sensor 2 upward, and the pressure sensor 2 measures the pressure it receives according to its deformation degree, and the load data of the ladder frame 1 can be obtained by corresponding conversion. Among them, the bottom surface of the arc-shaped contact boss 412 makes its force point appear at the center, which can more accurately transmit the pressure generated by its deformation to the bearing column 42.

[0050] In a preferred embodiment, the contact member 41 is made of rubber material, so that the contact member is easier to deform. The abutment column 42 is made of metal material, and the abutment column 42 can be a steel column, a copper column, etc., so that the strength of the abutment column is higher and the pressure result of the pressure sensor is more accurate.

[0051] Furthermore, as attached Figure 3As shown, a mounting groove 11 is provided at the bottom of the ladder frame 1, and the pressure sensor 2 is embedded in the mounting groove 11. The contact member 41 is installed below the mounting groove 11. The mounting groove 11 and the pressure sensor 2 in the mounting groove 11 are covered by the contact member 41, and the contact member is pressed against the bottom of the pressure sensor. When the bottom of the contact member is compressed and deformed, the abutment column protrudes upward and is higher than the top surface of the contact member. At this time, the pressure applied by the abutment column to the pressure sensor indicates the load condition of the ladder frame.

[0052] Specifically, a first connection portion 12 is provided at the bottom of the ladder frame 1, and a second connection portion 411 is provided on the peripheral side of the contact member 41. Holes are provided on the first connection portion 12 and the second connection portion 411, and the first connection portion 12 and the second connection portion 411 are connected and locked by bolts.

[0053] Furthermore, in order to enable the intelligent ladder to automatically remind the user of its load status, in a preferred embodiment, a sound unit is provided on the display module 3, and the sound unit is a speaker. When the pressure sensor 2 detects that there is a load on the ladder frame 1, the display module 3 obtains the information and makes a voice prompt through the speaker. In this embodiment, the connection structure between the sound unit, the information processing unit, each pressure sensor and the display module is as shown in the attached figure. Fig. 9 shown.

[0054] In other embodiments, a sounding unit may be provided on the ladder frame 1, and the sounding unit is electrically connected to the pressure sensor 2. The sounding unit is a buzzer. When the pressure sensor 2 detects that the ladder frame 1 is overloaded, the sounding unit emits an alarm sound. In this other embodiment, the connection structure between the sounding unit, the information processing unit, each pressure sensor and the display module is as shown in the attached figure. Fig.10 shown.

[0055] Further, in one embodiment, the ladder frame 1 is designed with a folding ladder structure, specifically, the ladder frame 1 includes a first support frame 101 and a second support frame 102.

That is, the foldable ladder frame 1 can be a ladder of a tripod ladder, a quadrangular ladder, a hexagonal ladder, an octagonal ladder, etc., and the pressure sensor 2 can be installed on any support leg 13 to achieve the purpose of detecting the load.

[0056] Of course, in order to make the detection result more accurate, in a preferred embodiment, a plurality of pressure sensors 2 are provided, and the number of pressure sensors 2 is the same as the number of supporting feet 13, and a pressure sensor 2 is installed at the bottom of each supporting foot 13. Correspondingly, a mounting groove 11 is provided at the bottom of each supporting foot 13, and a force-bearing member 4 is installed at the bottom of each supporting foot 13. The data collected by each pressure sensor 2 is concentrated in the information processing unit for conversion processing, and the conversion form is similar to that of an electronic scale. The accurate data after conversion processing by the information processing unit is sent to the display module 3, and the data is presented by the display screen.

[0057] In addition, for the embodiment in which the display is installed on the ladder frame 1, the display module 3 is specifically installed on the first support frame 101 through a clamping mechanism. The first support frame 101 and the second support frame 102 are both hollow inside and form a wire passage 14. The wire passage 14 extends downward and is connected to the installation groove 11. The pressure sensor 2 is electrically connected to the display module 3 through a wire 5. The wire 5 passes through the wire passage 14. The wire 5 inside the second support frame 102 can extend from the top of the second support frame 102 and then be connected to the display module 3. Alternatively, the wire 5 inside the second support frame 102 can pass through the hinge axis between the second support frame 102 and the first support frame 101, and extend into the first support frame 101, and then merge with the wire 5 inside the first support frame 101 and connect to the display module 3 together. The distribution structure of the wire 5 is shown in the attached figure. Figure 8 shown.

[0058] In addition, as attached Figure 1 As shown, the first support frame 101 includes two first rods 1011 and a pedal group 103 rotatably arranged between the two first rods 1011, and the bottom of each first rod 1011 is a support foot 13. The second support frame 102 includes two second rods 1021 and a cross bar 1022 connecting the two second rods 1021, and the bottom of each second rod 1021 is also a support foot 13. After the pedal group 103 is unfolded, it can be overlapped on the cross bar 1022 to provide a flat surface for the user to stand on.

[0059] Regarding the clamping mechanism used by the display module 3, as shown in the attached Figure 7 As shown, two clamping bosses 31 are specifically provided on the back of the display module 3, and the two clamping bosses 31 are respectively against two side surfaces of one of the first rods 1011, and the two clamping bosses 31 are connected by bolts, and the two clamping bosses 31 can be driven to clamp the first rod 1011 together by screwing the bolts.
