Fig. 1 to 7 show one specific example of the pedal shaft connecting mechanism according to the present invention. This footboard hub connection mechanism includes: a pedal shaft 2 for mounting a pedal (not shown in the figure) and a crank 1. Wherein, the lower end of the crank 1 is provided with a mounting groove 11 and a first pivot hole 12 (see fig. 3 (a)), the tail end of the pedal shaft 2 is a square shaft section 21, the square shaft section 21 is provided with a second pivot hole 22, and the pedal shaft 2 is mounted at the mounting groove 11 of the crank 1 through a pin 5 inserted in the first pivot hole 12 and the second pivot hole 22. The mounting groove 11 is open at the bottom, i.e., bottom end, of the crank 1 to provide sufficient space for rotation or oscillation of the pedal shaft 2.
In some embodiments the attachment mechanism further comprises a stop 3, and the mounting slot 11 of the crank 1 has a deep recess at the side facing away from the footboard, i.e. towards the body of the scooter, and a space to accommodate part of the stop 3. When the pedal shaft 2 is positioned in the horizontal direction, namely in a working state, the pedal shaft 2 is approximately vertical to the crank 1, the stop block 3 is inserted into the mounting groove 11 and is arranged to a locking position close to the inner side wall of the deep groove part, and the lower surface of the stop block 3 is abutted against the upper end surface of the square shaft section 21 of the pedal shaft 2 so as to prevent the pedal shaft 2 from overturning. In the state in which the pedal shaft 2 is extended downward, i.e. in the vertical direction, the stop 3 is drawn out in the mounting groove 11, and the pedal shaft 2 is tilted downward into a position approximately collinear with the crank 1.
The working state refers to that the pedals and the pedal shafts 2 are treaded by a user to bear force so as to transmit power to a flywheel of the scooter, the stretching state refers to that the pedals and the pedal shafts 2 are turned downwards, and the pedal shafts are in the vertical direction so as to reduce the space occupied by the pedals and the pedal shafts 2 in the transverse direction. The tail end direction of the pedal plate can be realized by mounting the pedal shaft 2 on the pedal plate and taking one side of the original scooter as the head end, the connection part of the pedal shaft 2 and the crank 1 is the rear or the tail end, and the front and back directions of the stop block 3 are also the same. It will be appreciated that figures 6 and 7 are actually half-sectioned but not identified in section, the primary purpose of which is to show the structure within the mounting slot, and the positional relationship and cooperation between the various components.
The embodiment of the invention innovatively designs the connecting mode and the structure of the traditional pedal shaft 2 and the crank 1 of the existing bicycle, so that the pedal shaft 2 and the connected pedals can be downwards turned to be in the position approximately collinear with the crank 1, the occupied space of the pedals and the maximum thickness of the whole body part of the scooter are reduced, and the storage and batch transportation of the bicycle are facilitated.
In some embodiments, as shown in fig. 1, 2 and fig. 6 and 7, the stopper 3 not only serves as a force-bearing structure of the square shaft section 21 (the rear half section) of the pedal shaft 2 in the working state, but also can seal the pedal shaft 2 in the extended state to prevent the pedal shaft from swinging. Specifically, as shown in fig. 7, in the extended state of the pedal shaft 2, the inner end surface of the stopper 3 also serves to abut against the square shaft section 21 of the pedal shaft 2 that is flipped to be approximately collinear with the crank 1.
The crank 1 and the stop block 3 of the embodiment of the invention can be processed by injection molding and are integrally formed, thereby being convenient to manufacture and low in cost.
In some embodiments, as shown in fig. 4, the square shaft section 21 of the pedal shaft 2 has a substantially rectangular cross section, and the edge portions may be rounded or chamfered. The square shaft section 21 and the shaft section of the pedal shaft 2 for mounting the pedal can be integrally formed, and the surface of the square shaft section 21 contacting with the mounting groove 11 can be designed to be a plane. It will be appreciated that the pedal shaft of the present application may be of other suitable configurations that can be locked or unlocked by the stop.
In some embodiments, as shown in fig. 4 and 7, the square shaft section 21 of the pedal shaft 2 has a recess 23, and in the extended state, the inner end surface of the stopper 3 abuts against the recess 23 of the square shaft section 21 of the pedal shaft 2. Preferably, the concave portion 23 may be disposed at a junction portion between the rear end surface 203 of the square shaft section and the lower surface 202 of the square shaft section, and the structure of the concave portion 23 may be designed to correspond to a lower portion of the inner end surface of the stopper 3, so as to achieve seamless butt joint, and achieve a limiting effect of the stopper 3 according to the combination of the two, thereby preventing the pedal shaft 2 from swinging in the extended state.
In some embodiments, as shown in fig. 4, 5 and 6, the upper surface of the square shaft section 21 of the pedal shaft 2 has a first inclined surface 201a, and the lower surface of the inner end surface of the stopper 3 has a second inclined surface 302a, and the first inclined surface 201a and the second inclined surface 302a are matched with each other. Specifically, the first inclined surface 201a may occupy a portion of the upper surface 201 of the square shaft section, the lower surfaces 302 of the stoppers at the inner side end surfaces of the stoppers 3 may be the second inclined surfaces 302a, and the two surfaces in contact with each other are both inclined surfaces, so that the two surfaces are not prone to relative sliding in a working state, and force is transferred stably.
In some embodiments, the stop 3 may be connected to the crank 1 by a resilient biasing member 4. For example, as shown in fig. 5, 6 and 7, preferably, the upper surface or both surfaces perpendicular to the pin 5 of the block 3 is provided with a groove 31 for placing the elastic biasing member 4, and one end of the elastic biasing member 4 is connected to the first fastening structure 6 provided to the block 3 and the other end is connected to the second fastening structure 7 provided to the crank 1. The groove 31 may be provided on the upper surface 301 of the stopper 3 or on two opposite surfaces perpendicular to the pin 5, the depth of the groove 31 may be greater than or equal to the diameter of the resilient biasing member 4, the resilient biasing member 4 preferably being a spring that pulls the stopper inwardly. The purpose of the resilient biasing member 4 is to exert a certain pulling force on the stop 3 in the extended state, avoiding its position out of the mounting groove 11, and the resilient biasing member 4 also prevents the stop 3 from being lost.
The first fixing structure 6 and the second fixing structure can adopt screws which are fixed on the positions corresponding to the stop block 3 and the crank 1.
In some embodiments, as shown in fig. 5, the rear end of the stopper 3 is provided with a rough surface structure 32 or a protruding/recessed operation structure which is easy to manually operate. For example, the rough surface structure 32 may be a plurality of grooves arranged at intervals or a knurling process, and the operation structure may be a convex portion, a concave portion, a pull ring, or the like.
In some embodiments, as shown in fig. 3, 6 and 7, the mounting groove 11 comprises a shallow groove section at a side facing the distal end of the pedal shaft, comprising a through groove region 111, and a deep groove section at a side facing the body of the scooter, comprising an open groove region 112 and an overlying through groove. Above the through-groove region 111 is an open groove region 112, which open groove region 112 serves for mounting the stop 3 or as an accommodation space for the (rear half of the) square shaft section 21 of the crank 1 to be turned upwards. In the working state, the through groove area 111 of the mounting groove 11 is mainly used for the corresponding part of the square shaft section 21, and the open groove area 112 is mainly used for the corresponding stop block 3. In the extended state, the structure of the square shaft section 21 in front of the pin 5 is turned downward, and the structure behind the pin 5 is turned upward, that is, the tail of the square shaft section 21 is turned to the open groove area 112, the upper surface 201 of the square shaft section can abut against the vertical groove surface of the open groove area 112, and the concave part 23 of the square shaft section 21 is abutted by the end surface 303 on the inner side of the stopper.
In some embodiments, in the working state, the vertical groove bottom surface of the opening groove area 112 of the mounting groove 11 and the end surface 303 inside the stopper of the stopper 3 can be set to have a certain clearance.
The connecting mechanism provided by the embodiment of the invention comprises a crank 1, a pedal shaft 2, a stop block 3 and a tension spring. The crank 1 and the pedal shaft 2 can be hinged through a cylindrical pin or a pin shaft 5, the pedal shaft 2 can rotate around the cylindrical pin, the stop block 3 is arranged in the mounting groove 11 between the crank 1 and the pedal shaft 2, two ends of a tension spring can be fixedly connected to the crank 1 and the stop block 3 respectively through self-tapping screws, and the stop block 3 is plugged into a gap between the crank 1 and the mounting groove 11 of the pedal shaft 2 through the tension of the tension spring to limit the pedal shaft 2 and prevent the pedal shaft 2 from rotating; when the pedal needs to be folded, the stop block 3 is drawn out from the gap between the crank 1 and the mounting groove 11 of the pedal shaft 2, so that the pedal shaft 2 can rotate to a position approximately collinear with the crank 1, and then the stop block 3 is pulled back by the tension spring to abut against the pedal shaft 2, so that the rotation of the pedal shaft 2 is limited.
In some embodiments, as shown in fig. 3, the crank 1 has splines at its upper end positioned to connect to a sprocket spindle of a bicycle and a mounting groove 11 and a first pivot hole 12 at its lower end.
