Problems solved by technology

The feature of using flat pedals is that the installation position on the car bracket is generally high, and it is difficult to hold it smoothly. The habitual distance (i.e. amplitude) of pedaling is about 16cm, which limits the stroke of the input power, so the pedal structure of the prior art always has insufficient input power (or kinetic energy) when pedaling upright, resulting in too high a speed of the scooter. Low and unable to go uphill, and has no structural shifting effect

Embodiment 1

[0034] Embodiment 1: The single-power reciprocating speed change pedal structure of the flexible plate return type.

[0035] The structure of the reciprocating speed change pedal in this embodiment is a single-power reciprocating speed change pedal structure of the flexible plate return type, see figure 1 , it has a power pressure rod 2 that can be movably connected to the scooter frame 1, the power pressure rod 2 is actually movably connected to the vehicle frame 1 through the shaft 3, and the upper end of the power pressure rod 2 is movably connected with a movable pedal through the shaft 4 5 and the movable pedal is divided into two parts, the limit end 6 and the labor-saving end 7, and the movable connecting member 8 which can limit the movable pedal range of motion is arranged between the front part of the movable pedal limiting end and the vehicle bracket, and the movable connecting member Pull rope or zipper structure is adopted; the return mechanism A of the power pres...

Embodiment 2

[0039] Embodiment 2: Flexible board return type dual power reciprocating speed change pedal structure.

[0040] The structure of the reciprocating speed change pedal in this embodiment is a flexible plate return type double power reciprocating speed change pedal structure, see Figure 16-19 . Figure 16 Among them, the power pressure rod 2 is two sets of front and rear, which are connected as a whole to directly form a flexible plate structure. In the linkage of one up and one down, they form the return mechanism of the other side. The power output has two sets of independent ratchet systems. , also known as an off-axis double ratchet structure; Figure 17 and Figure 16 The structure is roughly the same, but the power output adopts a coaxial double ratchet structure. Figure 18 Among them, the power pressure rods 2 are also two sets of front and rear, and are coaxially movably connected on the vehicle bracket, and a connection return spring 19 is arranged between the two, ...

Embodiment 3

[0042] Embodiment 3: Elastic return type single power reciprocating speed change pedal structure.

[0043] The reciprocating speed change pedal structure of this embodiment is an elastic return type single power reciprocating speed change pedal structure, see Figure 21 . Figure 21 Among them, the return mechanism A of the power pressure rod 2 adopts a tension spring 21 structure, and can also be used Figure 22 shown in the structure of the torsion spring 22, of course Figure 21-22 Compression spring structure can also be used, Figure 23 bungee cord construction as shown or Figure 25-26 Shown shoe hook, shoe cover structure. In fact, the return mechanisms of all the solutions described in Embodiment 1 can be realized by using extension springs, compression springs, torsion springs, elastic cords, shoe hooks or shoe covers.

Abstract

The invention discloses a reciprocating type gear shift pedal structure for a scooter, comprising a power pressure rod (2) which can be movably connected with a scooter bracket (1) of the scooter. The reciprocating type gear shift pedal structure for a scooter is characterized by also comprising a power pressure rod returning mechanism (A) which can lead one end of the power pressure rod to scratch upwards, wherein the upper end of the power pressure rod (2) is movably connected with a movable pedal (5) by a shaft (4), the movable pedal is divided into a movable pedal limiting end and a movable pedal labor-saving end, and a movable connecting member (8) which can limit the motion range of the movable pedal is arranged between the front part of the movable pedal limiting end and the scooter bracket. The invention is used for a scooter with two to four wheels, the pedaling mode conforms to a human body standing and pedaling posture and is easy to smoothly exert force, meanwhile, the invention has high-level, middle-level and low-level shifting effects and high output power.

Description

Technical field [0001] The invention relates to a reciprocating speed change pedal structure for a scooter, belonging to the technical field of bicycles. Background technique [0002] In the published patent documents, the flexible pedals used on scooters generally adopt a straight flexible pedal structure, referred to as flat pedals, such as the scooters disclosed in Chinese patents ZL01237990.5 and ZL97230502.5. pedal structure. The feature of using flat pedals is that the installation position on the car bracket is generally high, and it is difficult to hold it smoothly. The habitual distance (i.e. amplitude) of pedaling is about 16cm, which limits the stroke of the input power, so the pedal structure of the prior art always has insufficient input power (or kinetic energy) when pedaling upright, resulting in too high a speed of the scooter. Low and unable to go uphill, and there is no structural shifting effect. Contents of the invention [0003] In view of the above...
