[0035] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.
[0036] The pedal assembly of the embodiment of the present utility model has a riding state and an assisting state and includes a vehicle body 1, a first crank 2, a second crank 3, and two limiting members 4.
[0037] Two first holes 11 are provided on the vehicle body 1. For example, as Figure 1As shown, the vehicle body 1 can be a frame structure, that is, the vehicle body 1 can be assembled by splicing steel beams, etc. In some other embodiments, the vehicle body 1 can also be an integral structure, that is, the vehicle body 1 can be composed of sheet metal, pipes, etc.
[0038] The first hole 11 can be provided on the side of the vehicle body 1, specifically, it can be provided on the left or right side of the vehicle body 1. The first hole 11 can have a quantity of two, three, four, etc. Some of the first holes 11 can be provided on the left side of the vehicle body 1, and some of the first holes 11 can be provided on the right side of the vehicle body 1.
[0039] At least one of the first crank 2 and the second crank 3 is detachably assembled to the vehicle body 1, and the vehicle body 1 is located between the first crank 2 and the second crank 3. For example, both the first crank 2 and the second crank 3 can generally be Z-shaped. Among them, the first crank 2 can be rotatably assembled on the left side of the vehicle body 1, and the second crank 3 can be rotatably assembled on the right side of the vehicle body 1. Both the first crank 2 and the second crank 3 are detachable relative to the vehicle body 1, and both the first crank 2 and the second crank 3 can be used to install pedals, etc., thus meeting the user's need to ride by stepping on the pedals.
[0040] When the pedal assembly is in the riding state, the extending directions of the first crank 2 and the second crank 3 are opposite. For example, as Figure 1 shown, the first crank 2 can generally extend forward, and the second crank 3 can generally extend backward. At this time, the user's two feet can step on the corresponding pedals respectively, thus meeting the need for riding by stepping.
[0041] When the pedal assembly is in the assisted state, the extending directions of the first crank 2 and the second crank 3 are the same. For example, as Figure 2 shown, both the first crank 2 and the second crank 3 can generally extend forward. At this time, the user's two feet can be placed side by side and step on the corresponding pedals respectively, meeting the need for resting the feet when riding with assistance.
[0042] In the assisted state, the limiting member 4 passes through the first crank 2 or the second crank 3 and is inserted into the first hole 11, and the limiting member 4 is connected to at least one of the first crank 2 and the vehicle body 1, or at least one of the second crank 3 and the vehicle body 1.
[0043] For example, the limiting member 4 can be a structural member such as a bolt. When the pedal assembly is switched to the assisted state, a limiting member 4 can be passed through the first crank 2 and inserted and assembled with the first hole 11 on the left side of the vehicle body 1, and the limiting member 4 can be fixed to the first crank 2 by means of clamping, screw assembly, etc. By means of this limiting member 4, the limiting and fixing of the first crank 2 can be realized.
[0044] Then, another limiting member 4 can pass through the second crank 3 and be inserted and assembled with the second hole 5 on the right side of the vehicle body 1, and the limiting member 4 can be fixed to the second crank 3 by means of clamping, threaded assembly, etc. The limiting of the second crank 3 can be achieved by means of the limiting member 4.
[0045] In some embodiments, the first crank 2 and the second crank 3 are both provided with a second hole 5. In the boosting state, the limiting member 4 is threadedly assembled in the second hole 5 and is inserted and assembled with the first hole 11.
[0046] For example, as Figure 3 shown, one second hole 5 can be provided on both the first crank 2 and the second crank 3. The second hole 5 can be a threaded hole, and an external thread 41 can be provided on the outer peripheral side of the limiting member 4. During assembly, a part of the limiting member 4 can pass through the corresponding second hole 5 on the outside of the first crank 2 or the second crank 3 and be inserted and assembled into the corresponding first hole 11, and the external thread 41 on the limiting member 4 can correspond to the second hole 5 and be in threaded cooperation with the second hole 5, as specifically shown in Figure 4 shown.
[0047] In some embodiments, the vehicle body 1 is provided with a third hole 12. In the riding state, the limiting member 4 is assembled in the third hole 12. For example, as Figure 5 shown, the third hole 12 can be provided on the front side of the second hole 5. When it is not necessary to keep the pedal assembly in the boosting state by means of the limiting member 4, the limiting member 4 can be fixed in the third hole 12, as shown in Figure 6 shown, thus meeting the need for storing the idle limiting member 4 and avoiding the situation that the limiting member 4 is easily lost when it is idle.
[0048] In some embodiments, in the riding state, the limiting member 4 is threadedly assembled in the third hole 12. For example, the third hole 12 can be a threaded hole, and the internal thread in the third hole 12 can be consistent with the internal thread in the above-mentioned second hole 5, so that the limiting member 4 can be respectively threadedly fixed to meet the assembly and use requirements in the second hole 5 or the third hole 12.
[0049] In some other embodiments, the limiting member 4 can also be received at the third hole 12 by means of clamping, interference fit, etc.
[0050] In some embodiments, the vehicle body 1 is provided with a protruding portion 13 protruding from the side surface of the vehicle body 1. For example, as Figure 5 shown, the material of the vehicle body 1 can be aluminum alloy, etc. The protruding portion 13 can be integrally formed on the vehicle body 1 by means of casting. The protruding portion 13 can generally be oval or runway-shaped, and the first hole 11 and the third hole 12 are both provided on the protruding portion 13.
[0051] Thus, the structural strength at the first hole 11 and the third hole 12 can be enhanced, avoiding the situation where the local strength of the vehicle body 1 is reduced due to the provision of the first hole 11 and the third hole 12.
[0052] In some embodiments, the first crank 2 and the second crank 3 are both provided with a second hole 5. In the assisting state, the limiting member 4 passes through the second hole 5 and is threadedly assembled in the first hole 11.
[0053] For example, as Figure 7 shown, both the first crank 2 and the second crank 3 can be provided with a second hole 5 for the corresponding limiting member 4 to pass through. The second hole 5 can be a round hole with a smooth hole wall, and the first hole 11 on the vehicle body 1 can be a threaded hole. During assembly, the limiting member 4 can pass through the second hole 5 and be threadedly engaged in the corresponding first hole 11.
[0054] In some embodiments, in the assisting state, both the first crank 2 and the second crank 3 are horizontally arranged, and both the first crank 2 and the second crank 3 extend towards the front or rear side of the vehicle body 1.
[0055] For example, when the pedal assembly switches to the assisting state, both the first crank 2 and the second crank 3 can switch to a substantially horizontal position, as Figure 4 shown, both the first crank 2 and the second crank 3 can extend forward. In some other embodiments, as Figure 8 shown, both the first crank 2 and the second crank 3 can also extend rearward.
[0056] In some other embodiments, when the pedal assembly is in the assisting state, both the first crank 2 and the second crank 3 can also be inclined. For example, the first crank 2 and the second crank 3 can be inclined upward forward.
[0057] In some embodiments, the vehicle body 1 includes a first longitudinal beam 14 and a second longitudinal beam 15. The first longitudinal beam 14 and the second longitudinal beam 15 both extend along the front-rear direction of the vehicle body 1 and are arranged at intervals in the width direction of the vehicle body 1. The first crank 2 and the second crank 3 are detachably assembled to the vehicle body 1. The first longitudinal beam 14 and the second longitudinal beam 15 are both provided with the first hole 11, and in the assisting state, the first longitudinal beam 14 and the second longitudinal beam 15 are both locked and fixed by at least one limiting member 4.
[0058] For example, as Figure 8 shown, the first longitudinal beam 14 and the second longitudinal beam 15 can be generally in the shape of long plates. The first longitudinal beam 14 and the second longitudinal beam 15 both extend along the front-rear direction, and the first longitudinal beam 14 and the second longitudinal beam 15 can be arranged in parallel at intervals in the left-right direction.
[0059] A first longitudinal beam 14 and a second longitudinal beam 15 may each be provided with a first hole 11 and a third hole 12. When the pedal assembly is in the riding state, the limit members 4 for locking the first crank 2 and the second crank 3 respectively may be assembled in the third holes 12 of the first longitudinal beam 14 and the second longitudinal beam 15 respectively. When the pedal assembly is in the assisting state, the limit members 4 for locking the first crank 2 and the second crank 3 respectively may be assembled in the first holes 11 of the first longitudinal beam 14 and the second longitudinal beam 15 respectively.
[0060] In some embodiments, as Figure 8 shown, the vehicle body 1 includes a tube body 16. The tube body 16 may generally be circular tubular. The tube body 16 extends along the width direction of the vehicle body 1 and passes through the first longitudinal beam 14 and the second longitudinal beam 15. The width direction of the vehicle body 1 may be the left-right direction. Wherein, the left end of the tube body 16 may pass through the first longitudinal beam 14 and expose from the left side of the first longitudinal beam 14, and the right end of the tube body 16 may pass through the second longitudinal beam 15 and expose from the right side of the second longitudinal beam 15.
[0061] The first crank 2 and the second crank 3 are respectively assembled at both ends of the tube body 16. For example, the tube body 16 may be rotatably assembled with a pivot shaft. The left and right ends of the pivot shaft expose from the left and right sides of the tube body 16 respectively. The first crank 2 may be non-rotatably assembled at the left end of the pivot shaft, and the second crank 3 may be non-rotatably assembled at the right end of the pivot shaft.
[0062] The scooter of the embodiment of the present invention will be described below.
[0063] The scooter of the embodiment of the present invention includes a pedal assembly, and the pedal assembly may be the pedal assembly described in any of the above embodiments. The scooter may be an electric bicycle (E-bike), a battery-powered vehicle, etc., and of course, it may also be other scooters with riding function and assisting function.
[0064] Although the above embodiments have been shown and described, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Any changes, modifications, substitutions, and variations made by those of ordinary skill in the art to the above embodiments are within the protection scope of the present invention.
