[0006] Preferably, a slide and a staircase are fixedly connected to the side walls at both ends of the wooden frame; a roof is connected to the top of the wooden frame; two sets of protective frames are fixedly connected to the side walls of the wooden frame, and the two sets of protective frames enclose the climbing board; multiple sets of force ropes are arranged in an arc shape on the side walls of the two sets of protective frames.

[0007] Preferably, a servo motor is bolted to the inner wall of the climbing board, and the servo motor drives the inner frame to rotate and connect with the inner wall of the climbing board; the top of the inner frame is recessed inward to form a connecting cavity, and a damper is connected to each of the four corners of the connecting cavity. The moving ends of multiple sets of dampers are fixedly connected to the four corners of the force plate, and a pressure sensor is fixedly connected inside the connecting cavity; multiple sets of climbing components are fixedly connected to the surface of the force plate.

[0008] Preferably, the force-bearing plate has multiple cavities formed by hollowing out, and the cavities are interconnected. An airbag is fixedly connected to the upper end of each cavity. One end of the piston frame in the second drive assembly is connected to the cavity inside the force-bearing plate through a first telescopic hose.

[0009] Preferably, the first drive assembly and the second drive assembly have the same structure, and the piston rod on the first drive assembly is fixedly connected to the second sliding plate; one end of the piston frame in the first drive assembly is connected to the air guide chamber through the second telescopic hose.

[0010] Preferably, the interior of the carrier plate is hollowed out to form an air guide cavity, which is connected to the guide frame, and the guide frame is fixedly connected to the top of the carrier plate.

[0011] Preferably, the guide frame is inserted into the sliding frame, the top of the sliding frame is fixedly connected to the pedal, and the carrying plate is provided with an unfolding component; when the carrying plate moves outward, the sliding frame drives the pedal to move outward, and the pedal moves away from the bottom end area of ​​the climbing board.

[0012] Preferably, the unfolding assembly includes a limiting frame, which is fixedly connected to the inner sidewall of the carrier plate. A receiving frame is fixedly connected to the sidewall of the limiting frame, and a spring is fixedly connected inside the receiving frame. The other end of the spring is fixedly connected to the drive rack.

[0013] Preferably, the drive rack is slidably connected to the limiting frame, the drive rack meshes with the drive gear and rotates within the limiting frame, and the shaft of the drive gear is fixedly connected to one end of the swing arm.

[0014] Preferably, the unfolding assembly is provided in two sets, the swing arms on the two sets of unfolding assemblies are respectively connected to the two ends of the buffer rope, the ends of the two sets of connecting ropes are connected to an elastic rope, and the elastic rope is fixedly connected to the side wall of the sliding frame.

[0015] The beneficial effects of this invention are:

[0016] This invention incorporates a pressure sensor within the force-bearing plate. When a child's hand or foot comes off the climbing component or their body impacts it, the sensor immediately detects the signal. A servo motor drives the inner frame and force-bearing plate to rotate downwards, initially reducing the tilt angle. A drive motor then moves the climbing board downwards and flattens it further, reducing the tilt angle between the climbing board and the horizontal plane a second time, while simultaneously lowering the overall height. This effectively shortens the vertical drop when a child falls and slows down the descent.

[0017] When the drive plate moves, the piston rod in the second drive assembly moves within the piston frame, compressing the air inside and delivering it to the cavity in the force plate. The airbag in the cavity expands, and the height of the airbag is higher than the height of the climbing board, so that the child's body comes into contact with the airbag when sliding down, and the hard contact is converted into a soft contact.

[0018] In this invention, the second sliding plate drives the air inside the first driving assembly to be delivered into the air guide cavity. The air pushes the sliding frame to move outward. When the carrying plate moves outward, the sliding frame drives the pedal to move outward, and the pedal moves away from the bottom end area of ​​the climbing board, so as to avoid collision between the child sliding down and the child on the pedal.

[0019] When the sliding frame in this invention moves the pedal outward, the sliding frame drives two sets of swing arms to rotate upward through the connecting rope. The two sets of swing arms drive the buffer rope to unfold, so that the unfolded buffer rope is located in the area below the climbing board. When the child slides down and loses his / her balance, the child's body comes into contact with the buffer rope, avoiding the child's body from colliding with the board and improving the child's safety during the climbing process.

[0030] To further explain the technical solution of the present invention, a detailed description is provided below through specific embodiments.

[0031] like Figures 1 to 3 As shown, the present invention provides a children's wooden house with a collision-proof protective structure, including a support frame 1, which is used to insert into the ground of the external installation area to provide support for the wooden house frame 2;

[0032] Among them, a control box is installed at the bottom of the wooden frame 2, and a controller is installed inside the control box. The controller is used to control the electrical components.

[0033] Specifically, slides 3 and stairs 4 are fixedly connected to the side walls at both ends of the wooden frame 2. The slide 3 can be made of high-density polyethylene. Children move to the wooden frame 2 via stairs 4 and then slide down slide 3 to the ground below.

[0034] like Figures 1 to 3 As shown, the top of the wooden frame 2 is connected to the roof 5; two sets of protective frames 6 are fixedly connected to the side walls of the wooden frame 2, and the two sets of protective frames 6 enclose the climbing board 20.

[0035] More specifically, the side wall of the wooden frame 2 above the two sets of protective frames 6 is hollowed out and forms a passage. The left and right ends of the passage are respectively connected to a barrier plate by torsion springs. When a child climbs to this area, the child pushes the barrier plate with his / her hands, and the two sets of barrier plates rotate inward, so that the passage opens and the child enters the interior of the wooden frame 2 through the passage.

[0036] like Figure 2 As shown, the two sets of protective frames 6 have multiple sets of force ropes 7 arranged in an arc shape on the side walls. When a child climbs on the climbing piece 23 on the force plate 22, the child's hands are separated from the climbing piece 23 and lean backward, and the child's back comes into contact with the force ropes 7. The multiple sets of force ropes 7 provide support for the child's back.

[0037] like Figure 3 and Figure 4 As shown, the side wall of the support frame 1 is bolted with a drive motor 8. The output shaft of the drive motor 8 drives the lead screw 9 to be internally threaded to one end of the drive plate 10. The output shaft of the drive motor 8 is fixedly connected to one end of the lead screw 9.

[0038] Among them, a concave frame 11 is fixedly connected to the bottom side wall of the wooden frame 2. The upper and lower ends of the concave frame 11 are respectively slidably connected to a first sliding plate 13 and a second sliding plate 15. A guide rod is fixedly connected to the center of the concave frame 11. The guide rod slides through the interior of the first sliding plate 13 and the second sliding plate 15.

[0039] Specifically, the first sliding plate 13 is rotatably connected to one end of the first connecting rod 12, and the second sliding plate 15 is rotatably connected to one end of the second connecting rod 14; the other ends of the first connecting rod 12 and the second connecting rod 14 are rotatably connected to the drive plate 10, and when the drive plate 10 moves, it pushes the first sliding plate 13 and the second sliding plate 15 to move through the first connecting rod 12 and the second connecting rod 14.

[0040] like Figure 4 As shown, a first drive assembly 16 is fixedly connected to the side wall of the concave frame 11, and a second drive assembly 17 is fixedly connected to the support frame 1.

[0041] The second drive assembly 17 includes a piston frame 171, which is fixedly connected to the support frame 1. A piston rod 172 is slidably connected inside the piston frame 171. The piston rod 172 moves inward and compresses the air inside the piston frame 171. The air is delivered to the cavity inside the force plate 22 through the first telescopic hose, which can inflate multiple airbags 24. The height of the airbags 24 is higher than the height of the climbing component 23, so that the downward sliding surface of the child contacts the airbags 24. The other end of the piston rod 172 is fixedly connected to the side wall of the drive plate 10. When the drive plate 10 moves, it drives the piston rod 172 to move together, providing power for the movement of the piston rod 172.

[0042] More specifically, one end of the piston frame 171 in the second drive assembly 17 is connected to the cavity inside the force plate 22 through the first telescopic hose, so that the air inside the piston frame 171 can be transported to the cavity or the air inside the cavity can be drawn back to the piston frame 171, and the inflation or deflation of the airbag 24 can be adjusted by the up and down movement of the climbing plate 20.

[0043] Among them, the movable end of the telescopic rod 18 located below the wooden frame 2 is fixedly connected to the load plate 19, and the fixed end of the telescopic rod 18 is fixedly connected to the side wall of the protective frame 6, providing a fixing effect for the telescopic rod 18;

[0044] like Figure 4 and Figure 5As shown, the first sliding plate 13 is rotatably connected to the upper end of the climbing plate 20. The first sliding plate 13 provides power for the up and down movement of the climbing plate 20. When the first sliding plate 13 moves downward, it drives the climbing plate 20 to move downward, and the climbing plate 20 pushes the moving end of the telescopic rod 18 to move outward. At this time, the tilt angle of the climbing plate 20 changes from high to low, and the lower end of the climbing plate 20 is rotatably connected to the moving end of the telescopic rod 18.

[0045] A servo motor is bolted to the inner wall of the climbing board 20, and the servo motor drives the inner frame 21 to rotate and connect with the inner wall of the climbing board 20.

[0046] like Figure 6 As shown, the climbing board 20 is in the shape of an opening, and the top of the inner frame 21 is recessed inward to form a connecting cavity. A damper is connected to each of the four corners of the connecting cavity. The moving ends of multiple sets of dampers are fixedly connected to the four corners of the force plate 22. A pressure sensor is fixedly connected inside the connecting cavity.

[0047] For example, when a child's hands or feet detach from the climbing member 23 while climbing the support plate 22, and the child's body impacts the climbing member 23, the climbing member 23 transmits the impact force to the support plate 22, which in turn transmits the force to the pressure sensor. The pressure sensor detects the signal, and the controller controls the drive motor 8 to run. Alternatively, if a child is too afraid to move after climbing above the support plate 22, the child can forcefully slap the support plate 22, causing the support plate 22 to transmit the force to the pressure sensor behind it.

[0048] Among them, multiple sets of climbing components 23 are fixedly connected to the surface of the load-bearing plate 22;

[0049] The load-bearing plate 22 has a hollowed-out structure forming multiple cavities that are interconnected. An airbag 24 is fixedly connected to the upper end of each cavity, and the airbag 24 inflates to provide protection.

[0050] The first drive assembly 16 and the second drive assembly 17 have the same structure, and the piston rod 172 on the first drive assembly 16 is fixedly connected to the second sliding plate 15.

[0051] In this configuration, one end of the piston frame 171 in the first drive assembly 16 is connected to the air guide chamber 191 via a second telescopic hose, which facilitates the delivery of air into the air guide chamber 191.

[0052] like Figure 7As shown, the interior of the carrier plate 19 is hollowed out to form an air guide cavity 191, which is connected to the interior of the guide frame 192. The guide frame 192 is L-shaped and hollowed out to connect with the air guide cavity 191. Air from the interior of the air guide cavity 191 is delivered to the interior of the guide frame 192, and then the air pressure pushes the sliding frame 193 to move. The bottom of the sliding frame 193 is connected to multiple sets of rollers, which slide in contact with the top of the carrier plate 19 to improve the smoothness of the movement of the sliding frame 193.

[0053] The guide frame 192 is fixedly connected to the top of the carrier plate 19. The guide frame 192 is inserted into the sliding frame 193. The top of the sliding frame 193 is fixedly connected to the pedal 194. The sliding frame 193 moves while driving the pedal 194 to move together. Handrails can be connected to the left and right ends of the top of the pedal 194.

[0054] like Figures 7 to 9 As shown, the loading platform 19 is provided with an unfolding assembly 195. Rollers can be connected to the four corners of the bottom of the loading platform 19. The loading platform 19 contacts the ground through the rollers, so that the loading platform 19 contacts the ground through the rollers when it moves.

[0055] The unfolding component 195 includes a limiting frame 1951, which is fixedly connected to the inner side wall of the carrier plate 19. A receiving frame 1952 is fixedly connected to the side wall of the limiting frame 1951. A spring is fixedly connected inside the receiving frame 1952. The other end of the spring is fixedly connected to the drive rack 1953. The spring provides power for the reset of the drive rack 1953.

[0056] Among them, the drive rack 1953 is slidably connected to the limiting frame 1951, and the end of the drive rack 1953 that is fixedly connected to the spring is slidably inserted into the receiving frame 1952. The drive rack 1953 meshes and drives the drive gear 1955 to rotate and connect with the limiting frame 1951. The axis of the drive gear 1955 is fixedly connected to one end of the swing arm 1956.

[0057] The unfolding component 195 has two sets. The swing arms 1956 on the two sets of unfolding components 195 are respectively connected to the two ends of the buffer rope 1957. The material of the buffer rope 1957 is a children's trampoline net or an elastic rope used in amusement equipment. The ends of the two sets of connecting ropes 1954 are connected to an elastic rope, and the elastic rope is fixedly connected to the side wall of the sliding frame 193.

[0058] When the sliding frame 193 moves, it can pull the elastic rope to move. When the movement of the drive rack 1953 reaches its maximum, the elastic rope is pulled and stretched as the sliding frame 193 continues to move.

[0059] More specifically, in use, children outside can move to the wooden frame 2 via the stairs 4 and then enter the interior of the wooden frame 2 to play, or slide down to the ground below via the slide 3;

[0060] When climbing, the child first steps on the step plate 194, then moves forward to the support plate 22. The child's hands and feet contact the climbing piece 23. The child climbs up the support plate 22 using his hands and feet. After climbing above the support plate 22, the child pushes the barrier plate into the interior of the wooden frame 2.

[0061] As the child climbs, their body impacts the force plate 22 and slides down. The force plate 22 presses against the pressure sensor inside the inner frame 21. The pressure sensor senses the pressure and controls the servo motor to run. The servo motor drives the inner frame 21 and the force plate 22 to rotate downwards, so that the tilt angle of the inner frame 21 and the force plate 22 becomes smaller for the first time.

[0062] At the same time, the drive motor 8 drives the lead screw 9 to rotate, the lead screw 9 drives the drive plate 10 to move, the drive plate 10 applies force to drive the first connecting rod 12 and the second connecting rod 14 to move, and the first connecting rod 12 and the second connecting rod 14 drive the first sliding plate 13 and the second sliding plate 15 to move closer to the middle area of ​​the concave frame 11.

[0063] The first sliding plate 13 drives the upper end of the climbing board 20 to move downward, and the lower end of the climbing board 20 pushes the moving end of the telescopic rod 18 and the load plate 19 to move outward. The climbing board 20 also drives the inner frame 21 and the force plate 22 inside to rotate downward, so that the inclination between the climbing board 20, the inner frame 21 and the force plate 22 and the horizontal plane decreases for the second time, and the height of the inner frame 21 and the force plate 22 is reduced to facilitate the subsequent downward movement of children.

[0064] When the drive plate 10 moves, it drives the piston rod 172 in the second drive assembly 17 to move within the piston frame 171, compressing the air inside and sending it to the cavity inside the force plate 22. The airbag 24 in the cavity expands. The height of the airbag 24 is higher than the height of the climbing board 20, so that the child's body comes into contact with the airbag 24 when sliding down, avoiding contact with the climbing component 23.

[0065] The second sliding plate 15 drives the air inside the first drive assembly 16 to be delivered into the air guide cavity 191. The air pushes the sliding frame 193 to move outward. When the carrier plate 19 moves outward, the sliding frame 193 drives the pedal 194 to move outward. The pedal 194 moves away from the bottom end area of ​​the climbing board 20 to avoid collision between the child sliding down and the child on the pedal 194.

[0066] When the sliding frame 193 moves the pedal 194 outward, the sliding frame 193 pulls the connecting rope 1954 to move. The connecting rope 1954 moves the drive rack 1953. The drive rack 1953 meshes and drives the drive gear 1955 to rotate. The drive gear 1955 drives the swing arm 1956 to rotate upward. The two sets of swing arms 1956 drive the buffer rope 1957 to unfold, so that the unfolded buffer rope 1957 is located in the area below the climbing board 20. When the child slides down and loses his balance, the child's body comes into contact with the buffer rope 1957, avoiding the child's body from colliding with the carrying board 19.

[0067] Subsequently, the servo motor and drive motor 8 control the above-mentioned components to reset, and the swing arm 1956 and buffer rope 1957 reset, rotate, and are stored on the carrier plate 19.

[0068] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention 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 embodiments or make equivalent substitutions for some of the technical features.
