[0001] This utility model relates to the field of bicycle technology, and more specifically to a foldable pedal bicycle. Background Technology

[0002] To carry passengers, modern bicycles are equipped with a seat on the rear wheel and pedals on both sides of the rear wheel. Since these pedals are usually fixed to the frame with bolts, the overall size of such bicycles is relatively large, making them prone to snagging on other objects when transporting them, which makes them inconvenient to use. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a foldable pedal bicycle that can fold and store the pedals to reduce the overall volume.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A foldable pedal bicycle includes: a frame, the frame including a rear wheel, and a seat provided above the rear wheel; The pedals are symmetrically arranged on both sides of the rear wheel. Each pedal includes a plate body and a fixed seat that is fixedly connected to the vehicle body. The plate body is provided with a connecting seat and is rotatably connected to the fixed seat through the connecting seat. A limiting mechanism and a locking mechanism are provided between the connecting seat and the fixed seat. The limiting mechanism is used to limit the rotation angle of the connecting seat relative to the fixed seat, and the locking mechanism is used to lock the connecting seat when it rotates to a preset angle relative to the fixed seat.

[0005] As a further improvement of this utility model, the connecting seat is provided with a first limiting surface and a second limiting surface on the side away from the plate body. The limiting mechanism is a limiting shaft provided on the fixed seat. The limiting shaft is provided between the first limiting surface and the second limiting surface. The limiting shaft is used to abut against the first limiting surface and the second limiting surface to limit the rotation angle of the connecting seat relative to the fixed seat.

[0006] As a further improvement of this utility model, the fixed base is provided with a plurality of support frames, which are arranged along the length direction of the limiting shaft, and the support frames are used to abut against the supporting limiting shaft.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals.

[0016] Figure 1-5 According to the first embodiment of this utility model, a foldable pedal bicycle includes: a bicycle body 1, which is not limited to a human-powered bicycle or an electric bicycle. In this embodiment, it is an electric bicycle. The bicycle body 1 includes a rear wheel 2, and a seat 3 is provided above the rear wheel 2. The seat 3 is fixedly connected to the bicycle body 1.

[0017] It also includes pedals 4 symmetrically arranged on both sides of the rear wheel 2. The pedals 4 include a plate 5 and a fixed seat 6 fixedly connected to the vehicle body 1. The plate 5 is provided with a connecting seat 7 and is rotatably connected to the fixed seat 6 through the connecting seat 7, so that the pedals 4 can be folded relative to the vehicle body 1. When not in use, the pedals 4 can be folded and stored to reduce the overall volume and reduce protruding parts.

[0018] Furthermore, a limiting mechanism and a locking mechanism are provided between the connecting seat 7 and the fixed seat 6. The limiting mechanism is used to limit the rotation angle of the connecting seat 7 relative to the fixed seat 6, thereby ensuring the controllability of the angle of the pedal 4, so as to avoid the pedal 4 from affecting the rotation of the rear wheel 2 and other parts of the vehicle body 1. The locking mechanism is used to lock the connecting seat 7 when it rotates to a preset angle relative to the fixed seat 6.

[0019] By setting up a locking mechanism, on the one hand, when the pedal 4 is in a horizontal use state, the locking mechanism can prevent the pedal 4 from flipping back and causing instability. On the other hand, when the pedal 4 is folded up and stored, the locking mechanism can prevent the pedal 4 from falling back due to vibration or other reasons.

[0020] Specifically, the connecting seat 7 is provided with a through rotating hole, which is rotatably connected to the fixed seat 6 via a rotating shaft.

[0021] Meanwhile, there are two connecting seats 7 and two fixing seats 6, and they are arranged symmetrically relative to the plate 5. In another embodiment, at least three connecting seats 7 and fixing seats 6 can be used to improve the overall connection strength.

[0022] Preferably, the connecting seat 7 is provided with a first limiting surface 8 and a second limiting surface 9 on the side away from the plate 5. The limiting mechanism is a limiting shaft 10 provided on the fixed seat 6. In this embodiment, the limiting shaft 10 is fixedly provided relative to the fixed seat 6. In another embodiment, the limiting shaft 10 can also be rotatably provided relative to the fixed seat 6 to improve flexibility. The limiting shaft 10 is provided between the first limiting surface 8 and the second limiting surface 9. The limiting shaft 10 is used to abut against the first limiting surface 8 and the second limiting surface 9 to limit the rotation angle of the connecting seat 7 relative to the fixed seat 6.

[0023] When the connecting seat 7 rotates in the forward or reverse direction relative to the fixed seat 6, the first limiting surface 8 or the second limiting surface 9 can abut against the limiting shaft 10, thereby limiting the rotation angle of the connecting seat 7 relative to the fixed seat 6. Specifically, in this embodiment, when the limiting shaft 10 is in contact with the first limiting surface 8 and the second limiting surface 9, the angle between the two connecting seats 7 is 90 degrees.

[0024] At the same time, when the limiting shaft 10 abuts against the first limiting surface 8, a gap is formed between the plate 5 and the vehicle body 1 to avoid the plate 5 interfering with the vehicle body 1.

[0025] By setting a first limiting surface 8 and a second limiting surface 9 on the connecting seat 7, the rotation angle can be limited in conjunction with the limiting shaft 10, while the overall structure can be made simple and compact, thereby reducing the overall volume.

[0026] Preferably, the side of the connecting seat 7 is provided with a mounting hole 12, and the locking mechanism is a positioning ball 13 provided at the mounting hole 12. The positioning ball 13 is composed of a housing, a spring and a ball, and is connected to the mounting hole 12 by means of the external thread of the housing. This part is the prior art and will not be described in detail here. The fixing seat 6 is provided with a first positioning hole 14 and a second positioning hole 15 corresponding to the positioning ball 13.

[0027] When in use, when the connecting seat 7 rotates to the point where the first limiting surface 8 contacts the limiting shaft 10, the pedal 4 is in a folded-down state. At this time, the positioning ball 13 connects to the first positioning hole 14 to lock the angle of the connecting seat 7 relative to the fixed seat 6. The operator can apply force to the plate 5 to separate the positioning ball 13 from the first positioning hole 14. At this time, the connecting seat 7 can rotate relative to the fixed seat 6. Then, through the rotation of the connecting seat 7, the limiting shaft 10 contacts the second limiting surface 9. At this time, the plate 5 is in a horizontal use state, and the positioning ball 13 connects to the second positioning hole 15 to lock the connecting seat 7 relative to the fixed seat 6.

[0028] Preferably, the first positioning hole 14 and the second positioning hole 15 are set at 90 degrees relative to the center of the rotating shaft of the connecting seat 7.

[0029] The 90-degree angle setting ensures that pedal 4 can be used horizontally and stored vertically.

[0030] Preferably, the plate body 5 includes a base 16 and a plate surface 17. The connecting seat 7 is connected to the base 16. The plate surface 17 is disposed above the base 16. An elastic buffer 18 is provided between the plate surface 17 and the base 16. The buffer 18 is specifically made of rubber to achieve elastic buffering performance. In another embodiment, the buffer 18 can also be made of a spring to achieve the elastic effect.

[0031] The buffer 18 reduces the impact on the base 16 when the operator steps on it, thereby improving the overall load-bearing capacity of the pedal 4.

[0032] Preferably, the vehicle body 1 includes a tubular connecting section 19, with a mounting seat at the bottom of the connecting section 19, and a fixing seat 6 connected to the side of the mounting seat away from the connecting section 19. The fixing seat 6, the mounting seat, and the connecting section 19 are fixed to each other by bolts.

[0033] Bolted connections make it easy to modify and use ordinary vehicles, and the manufacturing process is simple.

[0034] Figure 6 This is the second embodiment of the present invention. The difference from the first embodiment is that the fixed base 6 is provided with a plurality of support frames 11, which are arranged along the length direction of the limiting shaft 10. The support frames 11 are used to abut against the supporting limiting shaft 10.

[0035] The strength of the limiting shaft 10 can be increased by setting the support frame 11, thereby increasing the load capacity of the pedal 4.

[0036] Figure 7 This is the third embodiment of the present invention. The difference from the first embodiment is that the upper end of the fixing seat 6 forms a contact surface 20 that is compatible with the surface curvature of the connecting section 19, and the fixing seat 6 abuts against the contact section through the contact surface 20.

[0037] The curved contact surface 20 can improve the transmission of force when pedaling, thereby increasing the connection strength between the fixed seat 6 and the vehicle body 1.

[0038] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
