Description

Technical Field

[0001] The invention belongs to the technical field of balancing vehicles, and relates to a balancing vehicle with a swing pedal. Background Art

[0002] An existing pedal-type balancing vehicle includes a base, wheels are installed at both ends of the base, and two pedals are arranged on the top of the base. The pedals can swing relative to the base, and the balancing vehicle can be accelerated, decelerated or turned by the swinging of the pedals. The existing pedals have swing shafts on both sides, and the swing shafts and the base are swingably connected. When in use, the user stands on the pedals, and the two pedals bear the weight of the whole person. The human body pressure on the pedals is borne by the swing shafts, so the swing shafts are prone to bending, and the pedals are prone to poor rotation. In addition, the swing shaft needs to bear a large pressure, and the manufacturing material of the entire pedal has high requirements, which increases the manufacturing cost of the pedal. Summary of the invention

[0003] In view of the problems existing in the prior art, the present invention proposes a balancing vehicle with a swinging pedal, aiming to overcome the defect that the pedal swinging axis in the existing balancing vehicle is subjected to excessive force.

[0004] The present invention is achieved in that:

[0005] A balancing vehicle with a swinging pedal comprises a base and a pedal swingably arranged on the base, characterized in that a load-bearing member is arranged at the lower end of the pedal, the lower end of the load-bearing member abuts against the base, and when the pedal swings, the load-bearing member rolls on the base along the swinging track of the lower end of the pedal. The force of the pedal is mainly transmitted to the base through the load-bearing member, thereby reducing or avoiding the force on the swing shaft, reducing the risk of deformation of the swing shaft, reducing the strength requirement of the swing shaft, and ensuring the smoothness of the swing of the pedal.

[0006] Preferably, the load-bearing member is a roller, a ball or a roller, the base has a receiving cavity, the bottom wall of the receiving cavity is arc-shaped, and the load-bearing member rests on the bottom wall of the receiving cavity. The rolling friction between the load-bearing member and the base can reduce the friction resistance between the load-bearing member and the base.

[0007] Preferably, the lower surface of the pedal has a support portion extending downward, the support portion has a mounting groove opening downward, the load-bearing member is installed in the mounting groove, and the lower end of the load-bearing member protrudes downward relative to the support portion. The load-bearing member is embedded in the mounting groove from the opening of the mounting groove, which is convenient for installation. The lower end of the load-bearing member abuts against the base, and the load-bearing member will not be separated from the mounting groove from the opening of the mounting groove.

[0008] Preferably, swing shafts are arranged at both ends of the pedal, and a swing groove is arranged on the base, and the swing shaft is embedded in the swing groove. The groove wall of the swing groove can limit the swing shaft to prevent the pedal from detaching from the base.

[0009] Preferably, the upper end of the swing shaft is higher than the tread surface of the pedal, and the lower end of the swing shaft is lower than the tread surface of the swing shaft. The tread surface tends to be flush with the swing axis of the pedal, making the swing operation of the pedal more labor-saving. The swing shaft with a larger diameter can reduce the risk of the swing shaft breaking and improve the stability of the pedal installation.

[0010] Preferably, a semicircular groove is provided in the middle of the base, and the swing shaft at one end of the pedal is located in the semicircular groove. A positioning buckle is detachably provided in the middle of the base, and the positioning buckle limits the upward movement of the pedal. After the swing shaft is placed in the semicircular groove, the positioning buckle is fixed to the base to position the swing shaft, so as to facilitate the installation of the pedal.

[0011] Preferably, the side wall of the semicircular groove protrudes upward relative to the base to form a raised portion, and the positioning buckle has a clearance groove corresponding to the raised portion; the positioning buckle includes a fixing portion, the fixing portion is provided with a first hole position, the first hole position has a top wall and a bottom wall, the bottom wall of the first hole position has a second hole position, the width of the second hole position is smaller than the first hole position, and the first hole position and the second hole position have an opening located on the same side of the fixing portion. The raised portion is embedded in the clearance groove, so that the installation position of the positioning buckle is more accurate, and the positioning buckle position is prevented from being offset and against the swing shaft; the first hole position for installing the screw nut provided on the positioning buckle has a top wall that can cover the screw, and even if the positioning buckle is exposed and installed on the balance car, the screw will not be exposed, so that the positioning buckle is suitable for exposed installation, which increases the scope of application of the positioning buckle.

[0012] Preferably, a baffle is disposed on the periphery of the groove wall of the swing groove, and a spacing space is provided between the baffle and the groove wall of the swing groove. The baffle can protect the swing groove from deformation, and even if the baffle is deformed by collision, it is deformed toward the spacing space and will not affect the swing groove, thereby ensuring the smooth rotation of the swing shaft in the swing groove.

[0013] Preferably, the two ends of the pedal have a reinforcement plate extending downward, the lower end of the swing shaft is connected to the reinforcement plate, and the end of the pedal has a shield corresponding to the interval, and the shield covers the interval. Since the pedal is thin, the reinforcement plate can strengthen the connection strength between the swing shaft and the pedal.

[0014] Preferably, the lower surface of the pedal has a limit portion extending downward, and the base is provided with a pair of retaining ribs corresponding to the limit portion, and the limit portion swings between the retaining ribs. When the pedal swings to the limit position, the retaining ribs abut against the limit portion to prevent the limit portion from swinging back and forth. The retaining ribs on the base limit the front and back swing of the limit portion, thereby limiting the swing angle of the pedal. In this way, the vertical deformation of the pedal has less influence on the front and back swing of the limit portion, making the limit swing angle of the pedal more stable, which is conducive to the user to more accurately grasp the swing angle of the pedal, and can also reduce the strength requirements of the pedal manufacturing material. The manufacturing material of the pedal has a larger selection space, which is conducive to reducing the manufacturing cost of the balance car.

[0015] The present invention provides a balancing vehicle with a swinging pedal, in which the force of the pedal is mainly transmitted to the base through the load-bearing member, thereby reducing or avoiding the force on the swing shaft, reducing the risk of deformation of the swing shaft, reducing the strength requirement of the swing shaft, and ensuring the smoothness of the swing of the pedal.

DETAILED DESCRIPTION

[0029] The following will further describe the specific implementation of the present invention in combination with the accompanying drawings to make the technical solution of the present invention easier to understand and grasp. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0030] This embodiment provides a balancing vehicle, such as Figure 1-5 As shown, the balancing vehicle comprises a base 100 and a pedal 200 swingably arranged on the base 100. The speed and steering of the balancing vehicle can be controlled by swinging the pedal 200. A load-bearing member 300 is arranged at the lower end of the pedal 200. The lower end of the load-bearing member 300 abuts against the base 100. When the pedal 200 swings, the load-bearing member 300 rolls on the base 100 along the swinging track of the lower end of the pedal 200. Swinging shafts 210 are arranged at both ends of the pedal 200. A swinging groove 110 is arranged on the base 100. The swinging shaft 210 is embedded in the swinging groove 110. The groove wall of the swinging groove 110 can limit the swinging shaft 210 to prevent the pedal 200 from being separated from the base 100. The pressure of the human body on the pedal 200 mainly acts on the load-bearing member 300, and is transmitted to the base 100 through the load-bearing member 300, rather than acting on the swinging shaft 210. This reduces or avoids the force on the swing shaft 210, reduces the risk of deformation of the swing shaft 210, reduces the strength requirement of the swing shaft 210, and ensures the smooth swing of the pedal 200. Both ends of the base extend upward to form wheel covers, which can prevent the pedal from moving laterally.

[0031] like Figure 3-5 As shown, the load-bearing member 300 is a roller. The rolling friction between the load-bearing member 300 and the base 100 can reduce the friction resistance between the load-bearing member 300 and the base 100. In other optional embodiments, the load-bearing member 300 can also be a ball, a roller or a cylinder. The base has a receiving cavity, the bottom wall of the receiving cavity is arc-shaped, and the load-bearing member is against the bottom wall of the receiving cavity.

[0032] like Figure 3 , Figure 8As shown, the lower surface of the pedal 200 has a support portion 120 extending downward, and the support portion 120 has a mounting groove 121 with an opening facing downward. The load-bearing member 300 is installed in the mounting groove 121, and the lower end of the load-bearing member 300 protrudes downward relative to the support portion 120. The load-bearing member 300 is embedded in the mounting groove 121 from the opening of the mounting groove 121, which is convenient for installation. The lower end of the load-bearing member 300 and the base 100 are against each other, and the load-bearing member 300 will not be separated from the mounting groove 121 from the opening of the mounting groove 121. The mounting groove 121 includes a wheel groove in the middle and shaft grooves located on both sides of the wheel groove. The roller includes a wheel body and a wheel axle located on both sides of the wheel body. The wheel body is located in the wheel groove, and the wheel axle is located in the shaft groove.

[0033] like Figure 2 As shown, the upper end of the swing shaft 210 is higher than the tread surface of the pedal 200, and the lower end of the swing shaft 210 is lower than the tread surface of the swing shaft 210. The tread surface tends to be flush with the swing shaft 210 line of the pedal 200, making the swing operation of the pedal 200 by the foot more labor-saving. The swing shaft 210 with a larger diameter can reduce the risk of the swing shaft 210 breaking and improve the stability of the installation of the pedal 200. The tread surface is preferably flush with the swing shaft 210 line of the swing shaft 210.

[0034] A semicircular groove 130 is provided in the middle of the base 100, and a swing shaft 210 at one end of the pedal 200 is located in the semicircular groove 130. A positioning buckle 400 is detachably provided in the middle of the base 100, and the positioning buckle 400 limits the upward movement of the pedal 200. The two pedals 200 on the base 100 are arranged in the same semicircular groove 130. After the swing shaft 210 is placed in the semicircular groove 130, the positioning buckle 400 is fixed to the base 100 to position the swing shaft 210, so as to facilitate the installation of the pedal 200. The swing groove 110 includes an integral groove located at the end of the base 100 and a split groove located in the middle of the base 100. The integral groove is formed when the base 100 is formed, and the split groove is formed by the semicircular groove 130 and the positioning buckle 400. During installation, first, a swing shaft 210 on the pedal 200 is embedded in the integral groove, and then the other swing shaft 210 is embedded in the semicircular groove 130, and then the positioning buckle 400 is fixed to the base 100 to achieve the positioning of the pedal 200.

[0035] The side wall of the semicircular groove 130 protrudes upward relative to the base 100 to form a protrusion 131, and the positioning buckle 400 has a makeshift groove 410 corresponding to the protrusion 131; the positioning buckle 400 includes a fixing portion 420, and the fixing portion 420 is provided with a first hole position 421, the first hole position 421 has a top wall and a bottom wall, and the bottom wall of the first hole position 421 has a second hole position 422, the width of the second hole position 422 is smaller than the first hole position 421, and the first hole position 421 and the second hole position 422 have an opening located on the same side of the fixing portion 420. The protrusion 131 is embedded in the yield groove 410, so that the installation position of the positioning buckle 400 is more accurate, and the position of the positioning buckle 400 is prevented from being offset and pressing against the swing shaft 210; the first hole 421 for installing the screw 423 nut set on the positioning buckle 400 has a top wall that can cover the screw 423. Even if the positioning buckle 400 is installed exposed on the balancing car, the screw 423 will not be exposed, so that the positioning buckle 400 is suitable for exposed installation, which improves the application range of the positioning buckle 400.

[0036] like Figure 10-11 As shown, the fixing part 420 includes a first fixing part and a second fixing part, and at least one set of first hole positions 421 and second hole positions 422 are respectively provided on the first fixing part and the second fixing part. The base 100 has fixing holes 160 corresponding to the second hole positions 422, and the nut of the screw 423 is embedded in the first hole position 421. The screw 423 passes through the first hole position 421 and the fixing hole 160. After the screw 423 passes through the fixing hole 160, the screw 423 is tightened by the nut. The two fixing parts 420 facilitate fixing the positioning buckle 400 to the base 100 of the balancing vehicle more stably. Fig.12 As shown, the nut is square, so that the nut will not rotate in the first hole 421, reducing the risk of loosening.

[0037] like Fig.10 As shown, the opening direction of the first hole 421 of the first fixing part is opposite to the opening direction of the first hole 421 of the second fixing part. In this way, even if the screw 423 fixing the positioning buckle 400 is loose, the positioning buckle 400 is not easy to move to one side, thereby improving the reliability of the installation of the positioning buckle 400.

[0038] like Figure 1 , Figure 6 , Figure 8-9 As shown, a baffle 140 is disposed on the periphery of the groove wall of the swing groove 110, and a spacing space 141 is provided between the baffle 140 and the groove wall of the swing groove 110. The baffle 140 can protect the swing groove 110 from deformation. Even if the baffle 140 is deformed by collision, it is deformed toward the spacing space 141, and will not affect the swing groove 110, thereby ensuring the smooth rotation of the swing shaft 210 in the swing groove 110.

[0039] like Figure 8-9As shown, both ends of the pedal 200 have a reinforcing plate 220 extending downward, the lower end of the swing shaft 210 is connected to the reinforcing plate 220, and the end of the pedal 200 has a shielding plate 230 corresponding to the partition space 141, and the shielding plate 230 covers the partition space 141. Since the pedal 200 is relatively thin, the reinforcing plate 220 can strengthen the connection strength between the swing shaft 210 and the pedal 200.

[0040] like Figure 3 , Figure 6-8 As shown, the lower surface of the pedal 200 has a limit portion 240 extending downward, and the base 100 is provided with a pair of retaining ribs 150 corresponding to the limit portion 240. The limit portion 240 swings between the retaining ribs 150. When the pedal 200 swings to the limit position, the retaining ribs 150 abut the limit portion 240 to prevent the limit portion 240 from swinging back and forth. The retaining ribs 150 on the base 100 limit the front and back swing of the limit portion 240, thereby limiting the swing angle of the pedal 200. In this way, the vertical deformation of the pedal 200 has little effect on the front and back swing of the limit portion 240, making the limit swing angle of the pedal 200 more stable, which is conducive to the user to more accurately grasp the swing angle of the pedal 200, and can also reduce the strength requirements of the manufacturing material of the pedal 200. The manufacturing material of the pedal 200 has a larger selection space, which is conducive to reducing the manufacturing cost of the balance car.
