pedal device

technical field

The invention relates to a foot pedal device, in particular to a foot pedal device installed on a carrier for the rider's feet to step on.

Background technique

Nowadays, two-person locomotives are equipped with footrests on both sides of the car body of the rear seat of the locomotive for passengers to place their feet to improve the comfort of passengers when riding the locomotive. In the early design, the pedals are pivotally connected to both sides of the car body, and can be folded when not in use; when in use, the pedals are rotated out from the two sides of the car body of the rear seat of the locomotive for passengers to step on. Although the early pedals have a fairly simple structure, the pedals can be pivoted to be rotated out or folded because the user needs to bend over and hold the pedals in use, so in recent years Practitioners have invested in improvements one after another, hoping to improve the convenience of operating the pedals.

Please refer to Fig. 1, a kind of existing pedal device 9, this existing pedal device 9 is installed on both sides of the car body below the locomotive seat cushion by a base 91, one side of this base 91 is set There is a groove 911, and a locking piece 92 is accommodated in the groove 911, and the locking piece 92 is pushed by an elastic component 921, so that the locking piece 92 can be locked in a position of a pedal 93 The hole 931 makes the pedal 93 snap in place. The pedal 93 is pivotally connected to a pivot 912 on the base 91 through an assembly portion 932, and a torsion spring 94 and a swing arm 95 are sequentially installed on the assembly portion 932 of the pedal 93; A cover plate 96 is interposed between the arms 95 , and the cover plate 96 is used to limit and position the torsion spring 94 , and the torsion spring 94 is used for elastically pivoting the pedal 93 . The swing arm 95 has a first end 951 and a second end 952. The swing arm 95 is provided with a positioning hole 953 adjacent to the first end 951 to pivotally connect to a pivot member 971 of a cover 97. In addition, A protrusion 954 is disposed adjacent to the second end 952 . The cover 97 is aligned to cover the base 91 , thereby restricting the pedal 93 to be pivotally located between the base 91 and the cover 97 . An embodiment similar to this existing pedal device 9 has been disclosed in the Taiwan Publication No. I274005 "Flip-open type motorcycle rear pedal" patent.

After the existing foot pedal device 9 is assembled to the side end of the car body of a motorcycle rear seat, when the pedal 93 is located at the retracted position, the catch member 92 will be stuck in the positioning hole 931 of the pedal 93, The pedal 93 is fixed in place; at this time, the first end 951 of the swing arm 95 abuts against a protrusion 933 of the pedal 93, and the second end 952 of the swing arm 95 abuts against the engaging member 92 . When the pedal 93 in the positioning state is pushed in the folded direction to pivot, the protrusion 933 of the pedal 93 can push the first end 951 of the swing arm 95, so that the swing arm 95 pivots, and then the swing arm 95 pivots. The second end 952 of the swing arm 95 pushes the catch piece 92 to compress the elastic assembly 921 until the swing arm 95 abuts against the catch piece 92 by the protruding portion 954; The latching position of the pedal 93 enables the torsion spring 94 to drive the pedal 93 to pivot and convert to the unfolded state.

Therefore, this existing pedal device 9 can be used by passengers to directly press the pedal 93 toward the vehicle body with their feet, and the swing arm 95 arranged in the pedal 93 can be used to link the locking member 92 to generate The linear displacement enables the pedal 93 to be automatically rotated out and deployed. Therefore, during operation, the user does not need to bend down and pull the pedal 93 by hand, which greatly improves the convenience of operation and does not dirty the user's hands. However, the existing footrest device 9 needs to use quite a large number of components to realize the operation process, so the existing footrest device 9 is not easy to manufacture and assemble.

In addition, during the pivoting process of the pedal 93 to the unfolded state, the pedal 93 is pushed against the second end 952 of the swing arm 95 by the projection 933 to forcibly separate the protruding portion 954 and the engaging portion 954 from each other. The locking member 92 can pivot the swing arm 95 back to the initial position. Therefore, the extent of the protruding portion 954 protruding from the outer surface of the swing arm 95 needs to be controlled quite accurately. When protruding, it may cause the swing arm 95 to be difficult to be pushed by the protrusion 933 to pivot back to the initial position. That is, the extent to which the protruding portion 954 protrudes from the outer surface of the swing arm 95 will directly affect the smoothness of the operation of the existing pedal device 9, so the processing accuracy of the protruding portion 954 is required to be relatively high, and the relative improvement The manufacturing difficulty of this swing arm 95 is eliminated.

On the other hand, when the pedal 93 is pushed against the second end 952 of the swing arm 95 by the projection 933 to make the swing arm 95 reversely pivot back to the initial position, the protruding portion 954 and The locking part 92 is forcibly separated; after long-term use, the protruding part 954 is prone to wear and tear, so that the swing arm 95 cannot cooperate with the locking part 92 smoothly, and the existing pedal device 9 Lose original function, so the service life of this existing pedal device 9 is not long.

In view of this, there is still a need to improve the existing pedal device at present.

At the same time, the elastic member 52 also pushes the blocking piece 4 to pivot and return to the initial position, so that the blocking piece 4 extends into the folding positioning groove 23 of the pedal 2 again.

To sum up, the footrest device of the present invention can be used for the user to control the folding or unfolding of the footrest device with a more simplified structure, so that the footrest device can not only provide a convenient operation mode, It is also better than the existing pedal device in terms of the convenience of manufacture and assembly.

In addition, in the foot pedal device of the present invention, when the pedal is pivoted, each linked component can complete the action smoothly, so that the components are not prone to wear and tear, and even if there are some dimensional tolerances, the operation will not be reduced. Therefore, the dimensional tolerance limit during manufacture can be relaxed, the difficulty of manufacture can be reduced, and the service life of the pedal device can be extended at the same time.

Also, in the pedal device of the present invention, the pivoting portion of the pedal can be partially exposed at the side end of the base, so when the pedal is folded from the unfolded state, the user can see the pedal from the side end of the base. To the folding positioning groove of the pedal and the locking protrusion of the locking member, so that the pedal can be stopped when the locking protrusion is locked into the folding positioning groove, so as to avoid pushing too far The pedal directly jumps from the aforementioned third position to the second position, and cannot stay at the first position, so the convenience of operating the pedal device can be improved and operation errors can be avoided.
