These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0023] Embodiment 1

[0024] Refer to Figure 1 , Figure 3 and Figure 4, including a chassis 1, a mounting plate 2 and a foot pedal body 3. The mounting plate 2 is vertically and fixedly connected to the top of the chassis 1. A control box assembly 4 is provided at a position near the bottom end of the side surface of the mounting plate 2. The control box assembly 4 includes a control box body 10 and a battery assembly 11. During actual use, the battery assembly 11 can be replaced, which is prior art and will not be elaborated here. The battery assembly 11 is installed inside the control box body 10 near the bottom position. A control board 12 is installed at a position above the battery assembly 11 inside the control box body 10. The control board 12 is an existing controller technical device. A control button 13 is embedded in the side surface of the control box body 10. The control button 13 is one of the components of the control board 12 and belongs to a kind of controller technology. The control board 12 is controlled by pressing the control button 13, which will not be elaborated here too much. The control button 13 is connected to the control board 12. An infrared sensor 14 is also embedded in the mounting plate 2. After the infrared sensor 14 continuously detects the swing rod 6 within 5 minutes, it will be transmitted to the control board 12, and then the control board 12 will control the electromagnet 17 to cut off the power. If the infrared sensor 14 does not continuously detect the swing rod 6, the electromagnet 17 will work normally. The infrared sensor 14 is connected to the control board 12. A connecting shaft member 5 is rotatably connected to the mounting plate 2 through a bearing at a position above the control box assembly 4 on the mounting plate 2. A swing rod 6 is fixedly sleeved on the surface of the connecting shaft member 5. As Figure 3 shown, the swing rod 6 is fixed to the connecting shaft member 5, and the connecting shaft member 5 rotates on the mounting plate 2 through a bearing. In this way, the rotation of the swing rod 6 will drive the connecting shaft member 5 to rotate together. The foot pedal body 3 is installed at a position away from the mounting plate 2 at the bottom end of the swing rod 6.

[0025] Embodiment 2

[0026] Reference Figure 4 、 Figure 5 and Figure 6, a locking tooth disc 7 is fixed on the surface of the connecting shaft member 5. A square opening is also provided in the conical notch of the locking tooth disc 7. The shape of the locking tooth 20 matches the shapes of the above-mentioned conical notch and square opening, and is used to stably engage with the locking tooth disc 7 to prevent the locking tooth disc 7 from separating from the locking tooth 20 by itself. A self-locking assembly 8 is provided on the side of the mounting plate 2 close to the swing rod 6 and close to the connecting shaft member 5. The self-locking assembly 8 is clamped on the locking tooth disc 7 to lock the connecting shaft member 5. The self-locking assembly 8 is connected to the control box assembly 4, and the self-locking assembly 8 is operated to move through the control box assembly 4. The self-locking assembly 8 includes a sliding groove 15 opened on the mounting plate 2 and a sleeve plate 16 sleeved on the surface of the connecting shaft member 5. The sleeve plate 16 is a plate member sleeved on the surface of the connecting shaft member 5. The inner wall height of the sleeve plate 16 is greater than the sum of the locking tooth 20 and the locking tooth disc 7, so that the sleeve plate 16 has enough moving distance to separate the locking tooth 20 from the locking tooth disc 7. An electromagnet 17 is provided at the top of the inner wall of the sliding groove 15. The electromagnet 17 is a mature existing technology and will not be elaborated here. The electromagnet 17 is connected to the control plate 12 in the control box assembly 4. A guide rod 18 is vertically fixed inside the sliding groove 15. One end of the sleeve plate 16 away from the connecting shaft member 5 moves inside the sliding groove 15 and is movably sleeved on the surface of the guide rod 18. A magnet attachment 19 is provided at a position near the top of the end face of the sleeve plate 16 inside the sliding groove 15. The magnet attachment 19 is movably sleeved on the surface of the guide rod 18. A counterweight 21 is provided at a position directly below the magnet attachment 19 on the lower surface of the sleeve plate 16. The counterweight 21 is also movably sleeved on the surface of the guide rod 18. After the sleeve plate 16 is separated from the electromagnet 17, the counterweight 21 drives the sleeve plate 16 to move downward quickly by its own weight. After the sleeve plate 16 moves downward, it will drive the locking tooth 20 to engage with the locking tooth disc 7, thereby locking the position of the connecting shaft member 5, and then locking the swing rod 6 through the connecting shaft member 5, achieving the purpose of anti-collision protection and preventing children from being injured when they push the swing rod 6 during play and causing safety accidents. Locking teeth 20 are provided at the top of the inner wall of the sleeve plate 16 corresponding to the locking tooth disc 7. The locking teeth 20 and the locking tooth disc 7 are engaged with each other. When the device is in use, by pressing the control button 13, power is supplied to the electromagnet 17 through the control plate 12. After the electromagnet 17 is powered on, it adsorbs the magnet attachment upward. The upward movement of the magnet attachment drives the sleeve plate 16 and the counterweight to move upward together on the guide rod 18. The upward movement of the sleeve plate 16 will drive the locking tooth 20 to separate from the locking tooth disc 7, enabling the connecting shaft member 5 to rotate freely, so that the device can be used normally. If it is not in use, after the infrared sensor 14 detects the swing rod 6 in the above manner, the control plate 12 disconnects the power supply of the electromagnet 17. At this time, the magnet attachment will move downward on the guide rod 18 by the gravity of the counterweight and the sleeve plate 16 itself. The downward movement of the sleeve plate 16 will drive the locking tooth 20 to engage with the locking tooth disc 7 again, thereby locking the position of the connecting shaft member 5. In this state, it is very difficult for the connecting shaft member 5 to rotate.Therefore, it is very difficult to push the swing rod 6, thereby improving the anti-collision protection performance at this position;

[0027] Reference Figure 4 , a stabilizing component 22 is also provided at a position corresponding to the upper side of the sleeve plate 16 on the side surface of the mounting plate 2. The stabilizing component 22 includes a guide groove 23 and a limiting rod 24. The limiting rod 24 is vertically fixed inside the guide groove 23. A stabilizing rod 25 is movably sleeved on the surface of the limiting rod 24. One end of the stabilizing rod 25 is movably inside the guide groove 23, and the other end of the stabilizing rod 25 is fixedly connected to the top surface of the sleeve plate 16, which is used to stabilize the upper moving state of the sleeve plate 16. When the sleeve plate 16 moves, it will drive the stabilizing rod 25 to move up and down on the surface of the limiting rod 24, so that the top of the sleeve plate 16 can only move up and down.

[0028] Embodiment 3

[0029] Reference Figure 1 and Figure 2 , collision buffer members 26 are movably sleeved on both end faces of the foot pedal. The collision buffer members 26 include an "n"-shaped protective shell 27. The "n"-shaped protective shell 27 is movably sleeved on the surface of the foot pedal body 3. A cavity 28 is provided inside the "n"-shaped protective shell 27, and a sponge 29 is filled inside the cavity 28. The "n"-shaped protective shell 27 is sleeved at the positions where both ends of the foot pedal are likely to be touched. The "n"-shaped protective shell 27 serves as a buffer area, and a sponge 29 is also filled inside it. When the foot pedal touches a child, the collision buffer member 26 that is first contacted is the "n"-shaped protective shell 27 in the collision buffer member 26. The "n"-shaped protective shell 27 is flattened and the sponge 29 filled inside it is used to buffer the collision force, thereby achieving the effect of collision buffering and greatly reducing the harm caused by the collision.

[0030] Reference Figure 1 , an armrest member 9 is also fixed on the surface of the mounting plate 2. When the device is used, people hold on to the armrest member 9 to stabilize themselves.
