Description

Technical Field

[0001] The invention relates to the technical field of square-round trampolines, and in particular to a square-round trampoline which can prevent rollover and has intelligent game play. Background Art

[0002] As we all know, trampoline exercise is a kind of sports activity. Reasonable trampoline exercise has a very positive effect on our health. In order to improve the fun and entertainment of trampoline exercise, we propose a square and round trampoline that can prevent rollover and has intelligent gameplay.

[0003] Most of the existing trampolines are circular in structure, generally including a bottom support frame and a top protective frame. The bottom support frame and the top protective frame are interconnected by multiple vertical rods. The bottom support frame is connected to a bottom mesh by multiple connecting springs. When in use, the trampoline user enters the area of ​​the bottom mesh, and the trampoline user accumulates force by bending the legs and then jumps up. Multiple connecting spring disks cooperate with the trampoline user to form a bouncing operation. Patents with application numbers CN201711030347.0, CN201921654377.3 and CN201911062324.7 all have such a structure.

[0004] Although the above-mentioned prior art solutions provide a type of trampoline structure, most spring trampolines use a direct pulling method of springs or elastic ropes, and use springs or elastic ropes to pull the jumping mat by telescopic force to tighten the trampoline jumping mat. One disadvantage of this method is that the spring is too hard when it is first used, and the spring becomes soft after a period of use, which will reduce the trampoline experience. In addition, the trampoline cannot detect whether the trampoline user exceeds the carrying capacity of the trampoline. The safety needs to be further strengthened. The function is mostly a single function of bouncing assistance. There is no other intelligent interactive experience game play, and the fun needs to be further improved. Summary of the invention

[0005] 1. Technical issues to be resolved

The trampoline is also equipped with a weight detection system, which can detect whether the person on the trampoline exceeds the carrying range of the trampoline, making it safer. At the same time, as the trampoline is used, when the spring or elastic rope becomes soft, it can cooperate with the spring or elastic rope to form relative tension compensation, which is more practical.

The four trampoline legs 4 are each provided with a side opening 15, and the bottom mounting frame 2 is provided with four first guide holes 16 and four second guide holes 17. The four first guide holes 16 are respectively connected to the four trampoline legs 4, and the four second guide holes 17 are also respectively connected to the four trampoline legs 4. The four first traction ropes 11 pass through the four first guide holes 16, and the four second traction ropes 12 pass through the four second guide holes 17. Through the design of the compensation system, as the trampoline is used, when the spring or elastic rope becomes soft, it can cooperate with the spring or elastic rope to form a relative tension compensation to ensure the bouncing effect of the trampoline, which is more practical.

[0032] It should be further explained that a follower line 7 is provided on the bottom surface of the elastic jump cloth 6, and a through hole 18 is opened on the bottom mounting frame 2. The follower line 7 passes through the through hole 18, and the other end of the follower line 7 is fixedly connected to the bottom mounting frame 2, and the follower line 7 is fixedly connected to two vertical lines 19, and the ends of the two vertical lines 19 that are away from each other are fixedly connected to a reset spring 20. Two protective cylinders 21 are fixedly connected in the bottom mounting frame 2, and the two reset springs 20 are respectively fixedly connected to the two protective cylinders 21, so as to improve the detection coverage effect of the follower line 7 on the elastic jump cloth 6. A plurality of vertical assembly rods 8 are detachably installed on the bottom mounting frame 2, and the plurality of vertical assembly rods 8 are detachably connected to the top protective frame 1. The interactive terminal 3 is installed on the top protective frame 1. The wire 7 is connected to the magnet in the interactive terminal 3. During the jumping process, the trampoline user presses down the elastic jumping cloth 6, and the elastic jumping cloth 6 pulls the follow-up wire 7. The follow-up wire 7 pulls the magnet in the interactive terminal 3 to move in the interactive terminal 3. The Hall sensor in the interactive terminal 3 senses the change in the magnetic field and captures the data, so as to achieve the effect of collecting frequency and strength information according to the jumping status of the trampoline user. Further data is calculated by the internal single-chip microcomputer of the interactive terminal 3 and transmitted to the mobile phone through the Bluetooth antenna in the interactive terminal 3. The game applet in the mobile phone obtains the data and starts to change accordingly, so as to achieve the change of the mobile phone game applet corresponding to the change of the trampoline user when the trampoline user is exercising on the trampoline, and then realize the interactive game. A safety detection program is written in the internal single-chip microcomputer for detection. The adaptability of the trampoline user's weight to the trampoline's bearing range. The detection method of the safety detection program is to use the lever principle to calculate the lever balance condition. The principle is that the magnitude of the two forces acting on the lever is inversely proportional to their lever arms. The two forces are divided into power and resistance, and the following formula can be obtained: power × power arm = resistance × resistance arm, which can be expressed algebraically as F1·L1=F2·L2, where F1 represents power, L1 represents power arm, F2 represents resistance, and L2 represents resistance arm. A weight is placed on one side of the elastic trampoline 6 to obtain gravity F1. At this time, the two adjacent trampoline legs 4 serve as fulcrums, and the weight of the trampoline as a whole serves as the gravity F2 at the other end. The shortest horizontal distance from the weight to the fulcrum is L1, and the shortest horizontal distance from the center of gravity of the trampoline to the fulcrum is L2. The short distance is L2. According to the actual gravity F2 of the whole trampoline, the gravity of F1 is calculated, and the weight of the trampoline user is taken into account. If the weight of the trampoline user is greater than F1, the trampoline as a whole is at risk of tipping over. On the contrary, if the weight of the trampoline user is less than F1, the trampoline as a whole will not tip over. Through the configuration of the interactive terminal 3, information interaction can be formed with the mobile phone client to realize the interactive game corresponding to the changes in the mobile phone game, and the fun is further improved. In addition, a weight detection system is provided to detect whether the trampoline user exceeds the bearing range of the trampoline, which is safer. Two through-hole tubes 22 are fixedly connected to the top protective frame 1, and door plug rods 23 are slidably connected in the two through-hole tubes 22. The tops of the two door plug rods 23 are fixedly connected with synchronous hand rods 24.Two plug-in tubes 25 are fixedly connected inside the bottom mounting frame 2, and the two plug-in tubes 25 are matched with the two door plug rods 23 respectively.

[0033] In summary, the working process of the anti-rollover square-shaped trampoline with intelligent game play is as follows: when in use, the anti-rollover square-shaped trampoline with intelligent game play is first placed at the placement location, and the interactive terminal 3 is connected to the power supply, and then the safety detection of the trampoline personnel is realized through the interactive terminal 3. After the detection is completed, the two door plugs 23 are pulled upward by the synchronous hand lever 24 to form an entry channel for the trampoline personnel to enter the elastic trampoline cloth 6. When the trampoline personnel enters the elastic trampoline cloth 6, the two door plugs 23 are controlled to fall and reset to realize the protection of the entry channel, and the trampoline movement can be started. During the trampoline movement, the trampoline personnel press down the elastic trampoline cloth 6, and the elastic trampoline cloth 6 pulls the follow-up line 7. The follow-up line 7 pulls the magnet in the interactive terminal 3 to move in the interactive terminal 3, and the Hall sensor in the interactive terminal 3 senses the magnetic field change and captures the data, so as to achieve the goal of controlling the trampoline personnel according to the jumping state. The effect of collecting frequency and force information is achieved by the internal single-chip computer of the interactive terminal 3, and further data is obtained through the internal single-chip computer calculation of the interactive terminal 3, which is transmitted to the mobile phone through the Bluetooth antenna in the interactive terminal 3. The game applet in the mobile phone obtains the data and starts corresponding changes, so as to achieve the change of the mobile phone game applet corresponding to the trampoline exercise of the trampoline personnel and then realize the interactive game. With the use of the trampoline, when the spring or elastic rope becomes soft, the driving sleeve 14 exposed through the side opening 15 rotates the corresponding threaded rod 13, so that the threaded rod 13 controls the traction block 10 to move downward relative to the corresponding trampoline leg 4, and then achieves the synchronous traction drive of the first traction rope 11 and the second traction rope 12, so that the pulling of the fixed rod 9 can be realized, the installation distance of the elastic member 5 can be increased, and the elastic member 5 such as the spring or elastic rope can be cooperated to form relative tension compensation, so as to ensure the bouncing effect of the elastic jumping cloth 6, which is more practical.

[0034] During the calculation process of the safety detection program, since the gravity F2 of the trampoline is divided into F21 close to the end of the heavy object and F22 of the main body of the trampoline due to the fulcrum, the gravity of F1 is calculated. Taking F1 greater than 37.5kg as an example, if F1 is greater than 37.5kg, the trampoline will not tip over when a 37.5KG weight is placed in it; otherwise, it will tip over.

[0035] The weights are placed on different edges of the trampoline, and the corresponding trampoline gravity F22 and F21 are different. If the weight is placed on one side of the handrail:

[0036] F22=5kgx9.8m / s 2 =49N; L2=585.2mm; L1=74mm; F21=1.65kgx9.8 m / s 2 =16.17N

[0037] Therefore, F1 = F2XL2 / L1 = 49x585.2 / 74 = 387.5N;

[0038] And because, F1=Mg+F21=Mx9.8 m / s 2 +16.17N=387.5N,

[0039] So, M = (387.5N-16.17N) / 9.8m / s 2 =37.9kg>37.5kg

[0040] If it is on the side opposite to the handrail,

[0041] F22=6kg x9.8m / s 2 =58.8N; L2=585.2mm; L1=74mm; F21=0.5kgx9.8 m / s 2 =4.9N

[0042] Therefore, F1 = F2XL2 / L1 = 58.8x585.2 / 74 = 465N;

[0043] And because, F1=Mg+F21=Mx9.8 m / s 2 +4.9N=465N,

[0044] So, M = (465N-4.9N) / 9.8m / s 2 =46.9kg>37.5kg

[0045] If it is on the folded side,

[0046] F22=5.5kg x9.8m / s 2 =53.9N; L2=552.5mm; L1=74mm; F21=1kgx9.8 m / s 2 =9.8N

[0047] Therefore, F1 = F2XL2 / L1 = 53.9x552.5 / 74 = 402.4N;

[0048] And because, F1=Mg+F21=Mx9.8 m / s 2 +9.8N=402.4N,

[0049] So, M = (402.4N-9.8N) / 9.8m / s 2 =40kg>37.5kg

[0050] Conclusion: The weight of all edges must be greater than 37.5kg. Therefore, the requirement of not tipping over is met.
