In addition, the sunken degree of depth of ring channel is half of connecting plate 21 thickness, can make connecting plate 21 thickness at this position of ring channel not influence structural strength because of crossing low like this, can make compression spring 3 imbed the darker degree of depth in the ring channel again to make compression spring 3 obtain with ring channel and circular boss bigger area of contact and frictional resistance, strengthen fixed compression spring 3.
In addition, the diameter of the cross section of the second limiting groove 12 is equal to the diameter of the radial cross section of the compression spring 3, so that when the compression spring 3 is matched with the first limiting groove 11 and the second limiting groove 12, the compression spring 3 cannot move transversely and shake, and the positioning and fixing effects are achieved; in addition, the diameters of the first limiting groove 11, the second limiting groove 12 and the compression spring 3 are the same, when a user steps on the pedal, the stress direction of the compression spring 3 is guaranteed to be perpendicular to the upper surface and the lower surface of the compression spring all the time, accordingly, the maximum elastic recovery speed is obtained, and the rebound sensitivity of the pedal is improved. Without this setting, it is possible that the sensitivity is less sensitive.
In addition, the depth of the second limit groove 12 is half of the thickness of the pedal, so that the thickness of the pedal in the circular groove 10 is not too thin to affect the structural strength of the pedal; in addition, the compression spring 3 can be further extended into the pedal, so that the compression spring 3 obtains larger contact area and friction resistance with the pedal, the compression spring 3 is not easy to fall off, the structural strength of the pedal is ensured, and the compression spring 3 is strengthened and fixed.
In addition, compression spring 3, first spacing groove 11 and the spacing quantity of second are two and evenly distributed respectively, distribute towards the front and back both ends of footboard, set up two compression spring 3 and have stronger holding power for only being provided with a compression spring 3, and compare and set up three compression spring 3 and more economize on cost, improve compression spring 3's price/performance ratio.

The sum of the transverse length of the two reinforcing ribs 16 and the thickness of the baffle plate does not exceed the distance between the infrared emitter and the infrared receiver, and the transverse length of the reinforcing ribs 16 is the length of the reinforcing ribs 16 in the emission direction of the infrared emitter.
The sum of the transverse length of the two ribs 16 and the thickness of the baffle does not exceed the distance between the infrared emitter and the infrared receiver, so that the baffle can freely rise or fall without hindrance when a user steps on the pedal. If not, the baffle plate is influenced by resistance when ascending or descending.
In addition, one side of the reinforcing rib 16 is in contact with the baffle, the other side of the reinforcing rib 16 is in contact with the baffle seat 6, and the reinforcing rib 16 forms a stable triangular structure, so that the baffle is not easy to shake, the baffle is more stable when being fixed on the baffle seat 6, and the structural strength of the baffle is improved.

Referring to fig. 4, the baffle includes a blocking hole 17, the blocking hole 17 is disposed at an end of the baffle far from the pedal, the blocking hole 17 is a through hole, a diameter of the blocking hole 17 is greater than a diameter of the first hole, and a diameter of the blocking hole 17 is greater than a diameter of the second hole. The distance from the shielding hole 17 to the bottom end of the baffle is larger than the ascending distance of the baffle, and the bottom end of the baffle is the end which is not contacted with the baffle seat 6.
The user is when stepping on the footboard, step on when the one end that is close to wheel 18, the baffle can be along with descending, thereby it descends to drive to block hole 17, the baffle can block the infrared ray that infrared emitter launches, make infrared receiver not receive the infrared ray, step on when the one end of keeping away from wheel 18 as the user, compression spring 3 plays the effect of footboard strong point, thereby make the distance of baffle rebound, block hole 17 along with the baffle rises, the distance that blocks off hole 17 to the baffle bottom is greater than the infrared ray that infrared emitter launches still can be sheltered from to the baffle, make infrared receiver not receive the infrared ray, the feedback start signal that makes opto-coupler switch 8 can be stable. If not, when a user steps on the pedal, the infrared receiver may receive a signal transmitted by the infrared transmitter, and the feedback of the start signal may be unstable.
In addition, under the natural state of the pedal, infrared signals are emitted through the first through hole and then received by the infrared receiver through the second through hole, because the first through hole and the second through hole are horizontally aligned on the same straight line, when no other shielding object blocks the first through hole, the infrared receiver can accurately receive the signals, when the first through hole and the second through hole are not horizontally aligned on the same straight line, the light is transmitted along the straight line, the signals emitted by the infrared emitter can not be received by the receiver, and errors can exist during signal detection.
In addition, the diameter of the shielding hole 17 is larger than the diameter of the first hole and the diameter of the second hole, so that the precision is not required to be high in the manufacturing process of the shielding hole 17 relative to the precision in the manufacturing process of the first hole and the second hole, the precision in the manufacturing process of the shielding hole 17 is reduced, and the cost is reduced; in addition, the diameter that shelters from hole 17 is greater than the diameter in first hole and the diameter in second hole, has avoided sheltering from hole 17 because of the undersize leads to the user not trample the footboard and other parts of baffle have blocked infrared emitter, influence normal start signal's feedback, has consequently improved opto-coupler switch 8 feedback start signal's stability. If not, the stability of the signal is affected.
Optionally, the opto-coupler switch 8 includes infrared emitter and infrared receiver, infrared emitter and infrared receiver set up relatively, the material of baffle is light-tight material.
When the user steps on the footboard, the material of baffle is light-tight material, makes the infrared ray can not pierce through the baffle, and the baffle just can make the infrared ray can not be received by infrared receiver when rising or descending to make the enabling signal feedback go out, the signal that detects is more accurate.
The footboard is at natural state, and infrared signal launches through first through-hole, then is received by infrared receiver through the second through-hole, and first through-hole, second through-hole and shelter from hole 17 on same water straight line, and opto-coupler switch 8 is in the closure state. When a user steps on the pedal close to one side of the wheel 18, the user applies pressure to the pedal, the compression spring 3 is compressed, the shielding hole 17 of the baffle descends along with the pressing of the pedal, so that the shielding hole 17 is not on the same horizontal line with the first through hole and the second through hole, the part between the reinforcing rib 16 of the baffle and the shielding hole 17 blocks a signal emitted by the infrared emitter, the optical coupler switch 8 is in a disconnected state, and a feedback signal is further sent to the integrated circuit board 15 for processing, so that the starting of the balance car is controlled; when the user steps on the baffle of keeping away from wheel 18 one side, compression spring 3 is as the fulcrum, and the baffle can rise to block hole 17 also along with rising, block hole 17 and first through-hole and second through-hole not on same water flat line, the bottom of baffle and the part of sheltering from between the hole 17 block the signal that infrared emitter launched out, thereby opto-coupler switch 8 is in the off-state, feedback signal and then send into and handle on integrated circuit board 15, thereby the start-up of control balance car.
