The invention aims to provide an automatic lifting foot support for a bicycle. The bicycle heel brace has the advantages that the bicycle heel brace is designed and innovated, and can be automatically lifted when the bicycle starts to run, and can be automatically put down when the bicycle stops running.
The invention is realized by the following technical scheme.
The invention relates to an automatic lifting foot rest of a bicycle, which comprises a gear transmission assembly, a thread pushing assembly and a foot rest lifting device.
The gear assembly includes: wheel bearings, wheel bearing sleeves, pawl pairs, ratchet gear sets, and reversing gears. A wheel bearing sleeve is secured to the wheel bearing, and a pair of pawl pairs are coupled to the outer cylindrical surface of the wheel bearing sleeve by a stationary shaft with the two pawls of the pawl pairs facing opposite directions. The rotation of the wheel drives the wheel bearing to rotate, and then drives the pawl pair on the wheel bearing sleeve to rotate together, the ratchet wheel gear set formed by two ratchet gears with different radiuses is sleeved outside the wheel bearing sleeve, the two ratchet gears are respectively a large ratchet gear and a small ratchet gear, ratchet teeth with opposite directions are arranged on the inner walls of the two gears, and the pawl pair is matched with the two pawls with opposite directions, so that the effect that only one ratchet gear in the ratchet wheel set has actual working effect no matter the wheel rotates positively or reversely can be realized. When the pawl pair on the wheel bearing sleeve rotates along with the wheel in the forward direction, one pawl of the pawl pair is embedded into ratchet teeth on the inner wall of the large ratchet gear, so that the large ratchet gear is used as a driving gear to rotate along with the wheel in the forward direction, the torque direction output by the large ratchet gear to a next-stage device is reverse, at the moment, the other pawl of the pawl pair slides along the ratchet teeth on the inner wall of the small ratchet gear, and the small ratchet gear is used as a driven wheel to rotate in the reverse direction due to the engagement of the system; when the pawl pair on the wheel bearing sleeve rotates in the opposite direction with the wheel, the pawl of the pawl pair is embedded in the opposite direction, and the small ratchet gear rotates in the opposite direction with the wheel as the driving gear, and the large ratchet gear rotates in the forward direction as the driven wheel due to the engagement of the system. Because the small ratchet gear is meshed with a smaller reversing gear, when the small ratchet gear rotates reversely along with the wheel, the torque output direction is adjusted to be reverse through the reversing gear, so that the torque direction finally output to the next-stage device by the large ratchet gear and the reversing gear is reverse no matter whether the wheel rotates forwards or reversely, and the torque direction transmitted to the thread pushing device is unchanged.
The thread pushing assembly includes: a thread pushing device, a one-way ratchet wheel and a traversing sleeve. The head of the thread pushing device is a large gear meshed with the gear and the reversing gear simultaneously, and the bottom of the thread pushing device is a screw matched with the threads of the inner hole wall of the unidirectional ratchet wheel. When the screw thread pushing device rotates, the screw thread on the screw rod at the bottom rotates along the unscrewing direction, the unidirectional ratchet wheel matched with the screw rod axially deflects outwards, and the unidirectional ratchet wheel is not deflected continuously after the unidirectional ratchet wheel deflects outwards by a certain distance because the screwing length of the screw rod of the screw thread pushing device and the screw thread matched with the unidirectional ratchet wheel is fixed, but the unidirectional ratchet wheel is always kept at the maximum deflection position as long as the wheel keeps rotating all the time. A traversing sleeve is sleeved outside the unidirectional ratchet, the inner wall of the traversing sleeve is connected with a pawl through a fixed shaft, a smooth sliding block is fixed on the outer side of the traversing sleeve, balls for reducing sliding friction force of the unidirectional ratchet and the traversing sleeve are placed between radial contact surfaces of the unidirectional ratchet and the traversing sleeve, when the unidirectional ratchet is axially deflected outwards, the traversing sleeve sleeved outside the unidirectional ratchet and the smooth sliding block on the traversing sleeve are also deflected outwards along with the unidirectional ratchet along the axial direction, and at the moment, the pawl on the inner wall of the traversing sleeve can prevent the unidirectional ratchet from rotating along with a thread pushing device.
The foot support lifting device comprises a smooth inclined curved surface, a foot support connected with the smooth inclined curved surface, a spring, a frame connecting device and a fixed shaft sleeve. The smooth inclined curved surface on the heel brace elevating gear rotates due to the extrusion of the smooth sliding block on the traversing sleeve, thereby driving the heel brace connected with the heel brace elevating gear to rotate to a lifting state together, a spring is arranged between the heel brace elevating gear and the traversing sleeve, when a user parks the bicycle, the wheel stops rotating, the screw thread pushing device does not rotate any more, the unidirectional ratchet wheel is not outwards screwed out any more, the traversing sleeve can drive the unidirectional ratchet wheel to axially inwards deviate to an initial position due to the gravity of the heel brace and the elastic force along the axial direction given by the spring arranged between the heel brace elevating gear and the traversing sleeve, at the moment, the pawl on the inner wall of the traversing sleeve does not prevent the unidirectional ratchet wheel from rotating any more, the unidirectional ratchet wheel can rotate along the screw thread on the screw rod of the screw thread pushing device, the heel brace returns to a descending state again, at the moment, and the heel brace can be kept in the descending state all the time on the premise that the wheel does not rotate any more.
A frame connecting device is connected between the wheel bearing and the bicycle frame and is used for fixing the gear transmission assembly so as to strengthen the working stability of the whole automatic lifting foot support device; the reversing gear is connected with the large gear of the thread pushing device through two fixed shafts on the fixed shaft sleeve, and is used for fixedly maintaining the engagement of the reversing gear and the large gear on the thread pushing device, so that the continuity of work is ensured.
The invention combines the foot support and the wheel shaft through the gear transmission structure to realize the function of automatically lifting the foot support, when the wheel rotates, the foot support of the bicycle is automatically lifted, and when the wheel is static, the foot support is automatically put down.

Detailed Description
The invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 to 8, when a user rides and pushes or pushes in the forward direction, the rotation of the wheel drives the wheel bearing to rotate, and then drives the pair of pawls 13 on the wheel bearing sleeve 12 to rotate together, because the directions of the ratchet teeth of the inner walls of the two ratchet gears in the ratchet gear set 14 are opposite, when the pawl pair 13 on the wheel bearing sleeve 12 rotates along with the wheel in the forward direction, one pawl in the pawl pair 13 is embedded into the ratchet teeth of the inner wall of the large ratchet gear 141, so that the large ratchet gear 141 rotates along with the wheel in the forward direction as a driving gear, and at the moment, the other pawl in the pawl pair 13 slides along the ratchet teeth of the inner wall of the small ratchet gear 142, the pinion gear 142 rotates in reverse as a driven wheel due to engagement of the system; when the pair of pawls 13 on the wheel bearing sleeve 12 rotates in reverse with the wheel, the pawl engagement of the pair of pawls 13 is reversed, with the small ratchet gear 142 rotating in reverse with the wheel as the drive gear and the large ratchet gear 141 rotating in forward direction as the driven wheel due to the engagement of the system. Since the small ratchet gear 142 is meshed with a smaller reversing gear 15, when the small ratchet gear 142 rotates reversely along with the wheel, the torque output direction is adjusted to be reverse through the reversing gear 15, so that the torque directions of the large ratchet gear 141 and the reversing gear 15 which are finally output to the large gear 211 of the thread pushing device 21 are all reverse no matter whether the wheel rotates in the forward direction or the reverse direction, and the thread pushing device 21 is driven to rotate reversely; when the screw thread pushing device 21 rotates, the screw thread on the screw rod 212 rotates along the unscrewing direction, the unidirectional ratchet wheel 22 matched with the screw rod 212 axially deflects outwards, but the unidirectional ratchet wheel 22 is not deflected continuously after the unidirectional ratchet wheel 22 deflects outwards by a certain distance because of the certain screwing length of the screw rod 212 and the unidirectional ratchet wheel 22, and the unidirectional ratchet wheel 22 is always kept at the maximum deflection position as long as the wheel keeps rotating all the time; when the unidirectional ratchet 22 is axially offset outwards, the outside of the unidirectional ratchet 22 is sleeved with the traversing sleeve 23 and the smooth sliding block 232 on the traversing sleeve 23 is also axially offset outwards along with the unidirectional ratchet 22, and at the moment, the pawl 231 on the inner wall of the traversing sleeve 23 prevents the unidirectional ratchet 22 from rotating together with the thread pushing device 21. The smooth inclined curved surface 31 on the heel brace lifting device 3 is extruded by the smooth sliding block 232 on the traverse sleeve 23 to rotate so as to drive the heel brace 32 connected with the heel brace lifting device to rotate to a lifted state, a spring 33 is arranged between the heel brace lifting device 3 and the traverse sleeve 23, when a user parks the bicycle, the wheel stops rotating, the thread pushing device 21 does not rotate any more, the unidirectional ratchet 22 is not outwards rotated any more, due to the gravity of the heel brace 32 and the elastic force of the spring 33 arranged between the heel brace lifting device 3 and the traverse sleeve 23 along the axial inward direction, the traverse sleeve 23 drives the unidirectional ratchet 22 to deviate to the initial position along the axial inward direction, at this time, the pawl 231 traversing the inner wall of the sleeve 23 no longer prevents the unidirectional ratchet 22 from rotating, the unidirectional ratchet 22 can be screwed along the screw thread on the screw rod 212 of the screw thread pushing device 21, the foot support 32 will return to the descending state again, at this time, the foot support 32 will be kept in the descending state all the time due to the moment of the spring 33 itself and on the premise that the wheel does not rotate again.
