The present invention provides an electric booster mounted on pedal of bicycle, which is characterized by that it utilizes the research and innovation of attachment easiness of original components of bicycle and application position of booster to make the electric booster implement the defects of existent bicycle booster in the aspects of assembling structure and functional perfection, etc.. The device structure is beneficial to a user to complete the assembly and the use with the bicycle in a very short time, and can safely, reliably and relatively permanently provide the advancing assistance for the bicycle.

Referring to fig. 1 to 6, there are a schematic perspective view of an electric power assisting device assembled in a rear riding state of a bicycle, a schematic view of a general assembly perspective view, a partially disassembled perspective view and side view, and a schematic view of assembly of components on different sides. From the general structural features, the electric power assisting device mounted on the pedal of the bicycle comprises a housing 2, a main bracket 3, a shock pad 4, a power assisting unit 6 and a through hole unit 5, which are integrally attached. The shock pad 4 is fixedly connected to the top surface of the shell 2, the shell 2 is provided with a through hole 21 corresponding to the attachment and positioning of the through hole unit, the main support 3 is internally connected in the shell 2, the middle section of the main support 3 is provided with a through cavity 31 forming the through hole unit, and the side of the through hole unit 5 is provided with an anti-misoperation protection switch 53 of the signal access power assisting unit; the power assisting unit 6 is assembled based on the main bracket 3 and comprises a battery assembly 61, a motor wheel 62, a man-machine interaction assembly 63, a motor driving controller 64 and an angle speed regulator 65 which are electrically connected; the electric booster DLZLZZ is sleeved with the bicycle pedal 12 based on the through hole unit 5, and is pressed down in parallel by the shock pad until the outer tire 621 of the motor wheel 62 is contacted with the road surface, the angle governor 65 senses that the front end of the electric booster is inclined upwards, and the motor wheel 62 is driven to roll friction with the road surface through the motor drive controller 64 to assist in the travelling direction of the bicycle.

For an easy visual understanding of the above summary, a brief description is made with reference to the accompanying drawings as follows: the bicycle 1 shown in fig. 1 generally has a pair of left and right pedals 11, 12. The electric booster device can be independently connected with any pedal, and can also be used for synchronously connecting and replacing the pedals. When the pedal plate with the electric booster device attached to any side is stepped down and the outer tire is contacted with the road surface, the booster in the travelling direction can be provided through the angle speed regulator; and after foot replacement, the electric booster on the other side can continue boosting. As shown in fig. 2, the electric power assisting device is integrally assembled, and all parts of the electric related power assisting unit are assembled in the main support and the shell, so that the dustproof and waterproof security is effectively realized. Furthermore, as can be seen from fig. 1 and 3, the through hole unit 5 is designed to facilitate the assembly and connection of the device with the pedal, so that various pedals with smaller size difference than the standard pedal can be satisfied without additional fasteners such as screws. Moreover, through the reasonable layout of all parts of components of the power assisting unit based on the main support surrounding the through hole unit, the modularized embedded attachment structure improves the space utilization rate, ensures the attachment strength and stability of all the components, and pertinently improves the misoperation prevention protection function.

From the aspect of further refinement and optimization of each unit and each part of components, as shown in fig. 3, the through hole unit 5 includes a first collar 51 and a second collar 52 spliced and fixed on two ends of the through cavity 31, a U window 521 is formed on a side surface of the second collar 52 close to the motor wheel 62 (the other side collar is not fully shown), two-phase splicing forms a containing groove 512, and an inner top surface and an inner bottom surface of the two collars are both provided with anti-skid rubber pads 54. The anti-slip rubber pad can be directly adhered to the inner wall of the clamping ring, but the problem of falling off after long-term use or environmental influence is difficult to avoid. Therefore, in the illustrated embodiment, the top and bottom surfaces of the two clamping rings are respectively provided with a hollow hole, the anti-slip rubber pad is of a sheet structure with smooth single surface and convex ribs distributed on the other surface in a discrete manner, and the anti-slip rubber pad is clamped between the clamping rings and the through cavity in a manner that the smooth surface is opposite to the inner wall of the through cavity. Therefore, after the through hole units are assembled, the convex ribs penetrate out of the hollowed holes and are exposed in the space of the through hole units, the service life of the anti-skid rubber cushion can be prolonged, and the sleeved pedal plate is reliably guaranteed to reduce the falling risk. As shown in fig. 6, the body of the anti-misoperation protection switch 53 is a first magnetic switch 531 and is fixed in the main bracket 3, the side wall of the pressing plate elastic sheet 532 of the anti-misoperation protection switch 53 facing the body is provided with a magnetic block 533, and the pressing plate elastic sheet 532 is bent in an arc shape to protrude from the accommodating groove 512 and is exposed in the through hole unit. In this state, the magnet 533 is separated from the first magnetic switch 531, and the first magnetic switch 531 transmits a rotation-stopping protection signal to the booster unit 6. Thus, when the electric power assisting device is not assembled to the bicycle pedal, the motor wheel is not rotated due to abnormal starting of the power supply, so that automatic running of equipment or personal injury is avoided, and only when the electric power assisting device is assembled to the bicycle pedal, the pressing plate elastic sheet 532 is extruded by the bicycle pedal and straightened in the accommodating groove 512, the magnetic block 533 is in contact with the first magnetic switch 531, and the first magnetic switch 531 pauses sending of the rotation stopping protection signal, so that the power assisting function can be normally realized.

The main support 3 is a rigid integral molding piece, the main support 3 is distributed with a through cavity 31, a first containing cavity 32 for assembling and connecting a battery assembly 61, a second containing cavity 33 for assembling and connecting an anti-misoperation protection switch 53, and an inverted arc containing cavity 34 and a motor support 36 for assembling and connecting a motor wheel, wherein the first containing cavity 32 is distributed with a first clamping groove 321 facing the battery assembly 61 and assembled by inserting an angle governor 65, the top parts of the second containing cavity 33 and the inverted arc containing cavity 34 are provided with a second clamping groove 341 facing the assembled by inserting a motor driving controller 64, the bottom part of the inverted arc containing cavity 34 is provided with a third clamping groove 342 facing the assembled by inserting the motor support 36, and one end of the inverted arc containing cavity 34 far away from the through cavity 31 is provided with a carrier 35 facing the assembled and connected by the man-machine interaction assembly 63. Therefore, the battery assembly, the motor wheel, the motor driving controller, the auxiliary power supply 5V module, the man-machine interaction assembly, the misoperation prevention protection switch and the like are separated from each independent space of the main support, so that mutual damage caused by mutual collision is avoided, and shaking is avoided after the whole assembly; thereby being suitable for the bicycle to run on bumpy roads.

In view of the speed control of electric power assistance, the invention adopts the tilting property of the device to realize speed regulation. Specifically, the angle governor 65 is assembled by a first vertical substrate 651, a first rotating bracket 652, a first magnet 653 and a 49E hall sensor 654, wherein the first vertical substrate 651 is attached to the main bracket 3 and positioned in a first clamping groove 321 opposite to the bottom side of the through cavity 31, a first limit edge 655 is arranged on the vertical side of the first vertical substrate 651 away from the motor wheel 62, the first rotating bracket 652 is hung on the first vertical substrate 651 near the top of the first limit edge 655, and the bottom end is connected with the first magnet 653; the 49E hall sensor 654 is attached to the first vertical substrate 651 near the bottom. In the horizontal state of the electric booster, the first rotating support 652 is positioned against the first limiting edge 655, and the motor wheel does not rotate to output. While as the front end of the electric booster gradually tilts upward, the first rotating bracket 652 remains suspended and the first magnet 653 will rotate within the adjustable angle. The 49E hall sensor 654 senses a change in distance from the first magnet 653 and outputs a sensed signal for speed regulation to the motor drive controller 64, wherein the 49E hall sensor 654 is at least one of OH49E, S49E, SS E linear hall switches.

In practical applications, when the electric booster is attached to a bicycle pedal, there is a greater or lesser difference in weight in the fore-aft direction of the device, particularly on the rear side where the motor wheel is located. Therefore, when the shock pad is not trampled and applied with force, the device is easy to automatically turn over with the front end turned up, and when the anti-misoperation protection switch 53 is in a state of suspending sending of the anti-rotation protection signal, the motor wheel is driven to rotate accidentally under the condition that the angle speed regulator senses inclination, and thus the uncontrolled scenes such as automatic running, turning over and the like of the bicycle are caused. For this purpose, the invention considers the introduction of further security measures, thereby increasing a safety limit range for the rotation speed sensing area of the angle governor. Specifically, as shown in fig. 5, the booster unit 6 is provided with an anti-misoperation device 67 composed of a second vertical substrate 671, a second rotating bracket 672, a second magnet 673 and a second magnetic switch 674, wherein the second vertical substrate 671 is attached to the main bracket 3 and positioned in a first clamping groove 321 opposite to the bottom side of the through cavity 31, a second limiting edge 675 is arranged on the vertical side of the second vertical substrate 671 far from the motor wheel 62, the second rotating bracket 672 is hung on the second vertical substrate 671 near the top of the second limiting edge 675, and the bottom end is connected with the second magnet 673; the second magnetic switch 674 is connected to a side of the second vertical substrate 671 away from the second limiting edge 675. When the electric booster is in a horizontal state or in an inclined state in the speed regulation region, the second magnet 673 is separated from the second magnetic switch 674, and the second magnetic switch 674 is not signaled to the booster unit, i.e., in a function suspension state. When the electric booster is tilted beyond the maximum booster speed range, the second magnet is brought into contact with the second magnetic switch 674, and the second magnetic switch 674 sends a rotation-stopping protection signal to the booster unit, causing the motor drive controller 64 to stop the continuous drive of the motor wheel 62. As can be seen from the illustration, the first and second rotary brackets rotate synchronously with the tilting of the electric booster, except that the swingable amplitude d2 of the second rotary bracket is larger than the swingable amplitude d1 of the first rotary bracket. Under the condition of the swingable amplitude d1, the two rotating brackets only have the power-assisted speed regulation function on the premise that the anti-misoperation device does not have touch signaling, and when the first rotating bracket is limited to be positioned at the swingable amplitude d1 and the second rotating bracket breaks through and reaches the swingable amplitude d2, the anti-misoperation device limits the angle range of the driven rotation of the motor wheel, so that the safety performance of the device is improved.

The booster unit 6 is further provided with an auxiliary power supply 5V module 641 inserted and assembled in the second clamping groove 341; the battery assembly 61 comprises a battery pack 611, a wiring frame 612 and a battery protection board 613, wherein positive and negative bus terminals of the battery pack 611 are connected to a man-machine interaction assembly 63 of the power assisting unit through the battery protection board 613, and are connected to a motor driving controller 64 and an auxiliary power supply 5V module 641 by a branch circuit of the man-machine interaction assembly 63, and the wiring frame 612 is connected with a first clamping groove 321 arranged in the main bracket 3. Typically connected to the motor drive controller is a supply voltage of about 36V, 48V; the auxiliary power 5V module 641 is added for charging the portable electronic device. Therefore, the electric booster has the function of reverse charging to the outside through the USB power taking interface.

And the motor wheel 62 is attached to the motor bracket 36 provided in the main bracket 3, and both ends are fixed by nut shaft coupling. And the drive end (not shown) of the motor wheel 62 is electrically connected to a motor drive controller 64. And the outer ring of the motor wheel 62 is sleeved with an outer tire 621 to increase the friction force with the road surface, and the outer tire can be a solid rubber tire or an inflated rubber tire.

Further, the electric power assist device includes a front end panel 7 and a rear end panel 8 attached integrally with the housing 2, the main bracket 3. The main support 3 is opposite to the outer end wall surface of the front end panel, an LED lamp panel 9 of a controlled switch of the signal access man-machine interaction assembly is attached to the outer end wall surface, and the front end panel 7 is fixedly clamped with the outer end wall surface and corresponds to the LED lamp panel to transmit light. As the auxiliary function of the bicycle night driving road illumination, the LED lamp panel can be directly attached and fixed on the outer end wall surface by adopting a finished product part with more than 10 LED lamp beads densely distributed, and the outer end wall surface is connected and fixed with the front end panel through a buckle or a clamping groove, and the front end panel is smooth and concise as a whole, and can be an organic glass cover plate and a plastic cover plate which are transparent in a whole range or a part of the light shielding area and transparent in a specific area.

Furthermore, the man-machine interaction module 63 at least includes a voltage and margin display module 631, a charging interface 632, a USB power-taking interface 633 and a power switch 634, and of course, in the preferred embodiment, an anti-loss alarm module 635 and a debugging button 6351 thereof are also provided. And the rear panel 8 is provided with a transparent window, an interface hole, a button part and a soft rubber dustproof cover 81 which corresponds to the man-machine interaction assembly and is shielded by the corresponding interface Kong Richang. After the rear end panel and the man-machine interaction assembly are correspondingly assembled, a user can master the electric energy allowance of the electric power assisting device through the rear end panel to charge the device, and control such as mobile charging bank, switch control and anti-loss debugging is performed. Unlike the attachment structure and manner of the front panel 7, which is required to have high fitting strength due to the integration area corresponding to the main electric components, the main bracket 3 is provided with a socket and an attachment hole at the end of the carrier 35, the bottom side of the rear panel 8 is fitted with the socket and fixed with the main bracket by screwing, and the top side is also fixed with the housing 2 by screwing. The anti-loss alarm module 635 is connected with the bluetooth of the mobile phone of the user, and after the user completes pairing with the electric power assisting device through the bluetooth of the mobile phone, the anti-loss alarm module can provide positioning for the user, and alarm sounds prompt the electric power assisting device to be lost and find out an effective way in a short distance time and under a permission condition.

In addition to the above preferred embodiments, there are various other alternative embodiments as an essential component of the speed control of the electric assist device. Still taking angular speed regulation as an example, as shown in fig. 7, the angular speed regulator 66 is assembled by a casing 661, a cover plate 662, sliding brackets 663, 49E hall sensors 664, a magnet 665, and a gravity sliding-assisting sphere 666. Wherein the housing 661, cover 662 and 49E hall sensor 664 are fixedly attached to the main support 3 in a position opposite the cavity through the bottom of the cavity, and the sliding support 663 within the housing 661 slides linearly over the cover 662. And a square hole 6631 which is matched with the gravity sliding-assisting sphere 666 to roll is arranged in the sliding bracket 663, and magnets 665 are respectively inlaid at two end sides of the top of the sliding bracket 663 opposite to the 49E Hall sensor 664. Because the whole electric booster is inclined along with the change of the falling point of the gravity center of the pedal, the gravity sliding-assisting sphere 666 rolls from high position to low position in the range of 360 degrees of the three-dimensional orthogonal axis and drives the sliding bracket 663 to slide, and the 49E Hall sensor 664 senses the change of the distance between the gravity sliding-assisting sphere and the magnet 665 and outputs a sensing signal for speed regulation to the motor drive controller 64. Likewise, the 49E Hall sensor 664 has a plurality of switch models selectable.
