Description of the Invention: [Technical Field] The present invention relates to a driving unit for an electric bicycle comprising an electric motor and a housing, the electric motor being disposed in the housing;: medium=moving::ΓΓ:70 further comprising a pedal crankshaft or at least a stepping bearing, the pedal is stepped on a pedal, the pedal crankshaft or the stepping bearing is the same as (4) =1 the pedal crankshaft is connected with a component provided in the housing by a common output means The one that can transmit the torque is used to install a driving unit on the installation side of the electric bicycle. The = is provided with a - pedal frame and is provided with - one of the patent scopes as described above. The drive unit is connected to the bicycle frame, and 2疋 is connected with the material frame, and the pedal crankshaft or the stepping bearing is integrated in the drive unit. [Prior Art] The conventional technology sets the electric bicycle to a thunder..., hf The motor is located on the red-foot bearing of the bicycle frame. Here, the electric horse secrets the framed stepping bearing group (central motor type), where ★, the electric motor is connected to the stepping bearing or the pedaling device or the output means (AbMeb) to cause the transmission torque connection. The running wheel (Laufrad) limits the space on the stepping bearing. In order to improve the driving performance, it is desirable that the wheel frame is small, and the actual embodiment of the "Mittelmotor" is limited in shape, so that the wheel frame becomes large. Finally, the complicated connection between the electric motor unit, the frame and the handle is made. The 201221410 has to be oriented and the structure of the drive unit of the bicycle. Because the electric motor is not only installed, but the moving column is connected. The way the transmission moves, in addition, can be selected and fixed. SUMMARY OF THE INVENTION The drive item of the independent item is achieved by the installation method of the patent application scope. According to the invention, it can be installed much simpler in the driving unit, and the connection structure between the hand and the bicycle frame, in addition to the high integration density, which makes the connection between the electric motor, the chain and the frame complicated and complicated. The reduction is made, the orientation of the drive unit relative to the frame can be modified; the same drive unit can be placed under the frame or within the frame triangle without changing the fixed configuration. Compared to the prior art, it is much simpler to fix the pivoting element to the frame. For electric bicycles with medium motors, a tighter drive unit is created. The typical frame geometry of the bicycle can be maintained, and the Radstand can be short. The output hand # is also caused by a hole crown (L〇ehkranz), which is of a general geometry and can be mounted on a drive chain gear. ◎ Power can be transmitted to the rear wheel by conventional bicycle components. So for example, multiple Chain gear (on the pedal bearing) or belt. This is caused by a (should be a single) standardized interface to drive the series. In the present invention, the drive unit to be mounted on the bicycle frame is not only an electric motor unit (electric motor and a linker) but also an element of the pedal drive unit. In particular, the connection force means is also provided on the drive unit. . Can the driver's serial interface left by the bicycle make a general bicycle component? 5 201221410 (Verban) (crank, circuit, sprocket, chain...), provided that the drive elements and electric drives that carry the leg force are integrated into a tight structural group. Therefore, the present invention is started by a unit of an electric drive and a pedal driver, which is further provided with a force output means. Therefore, the frame only has a static target @^ without any kinetic components (bearings, cranks...) associated with the pedal drive, especially all moving drive components (regardless of the rear wheel and the associated chain) are set to a unit shape, To install the drive, simply attach the drive unit (statically) to the frame without connecting the drive components to transmit motion, in particular without having to connect the electric motor to a force output (the pedal drive also acts on it). Due to the simplification of the fixing and the high degree of integration, the drive unit can be mounted by some solid means, which can be highly flexible in terms of the orientation of the drive unit. And in the shape of the frame, the degree of freedom of design can be greatly improved. All of the kneading surfaces associated with the bicycle drive train change with rotation as they rotate about the pedal axis. This allows the drive unit to be built around the axis without affecting the function. In the case of the related formation of the frame, for example, the motor can be mounted under the frame string or by 18 turns. Installed in frame triangle three, using the same drive unit as the same fixed element used in the various possible ways. ^ Since the pedal crankshaft (and the stepping bearing) is integrated in the driving of the present invention, when the driving unit is mounted, not only the components of the electric driver are connected to the frame, but also the components of the pedaling driver are connected (especially Step on the bearing and the pedal crank shaft provided in it). The simple 2 i ^ person I can easily drive the driver (package 3 by the motor unit and the pedal drive unit) to stop the box on the frame, especially when stepping on the shaft (also known as the pedal crankshaft) Already the drive unit ^ 6 201221410 2 = 2: It is especially lacking when it is completely connected to the motor unit or the output means. Only static connection with the frame (with the transmission of mechanical rotation movement), the fixing operation is simpler, and the driving movement is relative to the $w 3 electric motor of the bicycle frame. The use of different pedals is improved, so the same type The driving unit is the same as the grounding degree of the ground motion. The invention relates to a driving unit for an electric bicycle, wherein the driving unit is an early μ3-electric motor and a casing. In the casing towel, the drive unit has a pedal crankshaft 1 which is also provided in the casing, and the shank is provided with a pedal joint end. The pedal crank can be fixed thereto. The step = is also set in the housing. Here, the pedal joint end protrudes from the housing, and: the plate crank shaft can be fixed thereto. If this is not the case, the drive L 2 = Γ can be mounted in the housing with a recess in the housing. The pedals are second and extend through the recess so that the unit can be coupled to the pedal crank. Whether the drive unit only includes a stepping bearing or a pedal crankshaft, : are considered equivalent. Therefore, these possible ways can also be implemented in the same way as the 'should of the pedal drive and the electric motor in the common drive unit _ and use the common housing (for common). Since the stepping bearing requires 2 shanks for full function, the stepped bearing can be implemented without the pedaling drive unit, since the pedal crankshaft is to be manufactured. ...in addition, the pedal crankshaft is connected to the driveable torque by means of the components provided in the housing and the door ϊ 平 平 丑 丑 ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( 7 201221410 Drive unit - In the preferred embodiment, another motor coupler is connected to the electric motor. The motor coupler can be mounted in the housing. The output means can be directly connected to the pedal crank shaft. In addition, the pedal crank shaft can be passed through a The first coupling is connected to the output means, and the motor can be connected to the output means via the motor coupling, so that the output means combines the two drives. The output means can comprise a power output shaft, in particular another frame strip. It has a fixed component [ For example, spoke wheels [(Spader)], which are suitable for fixing at least one sprocket, according to a particular embodiment, the output shaft is equivalent to a pedal crankshaft (the electric motor is connected thereto via a coupling). In addition, the drive unit has bearings Components, which support the pedal crankshaft in the drive unit, the bearing components are also mounted in the housing, and the bearing component should include a stepped bearing housing with a pedal crankshaft The 1 bearing element and the pedal bearing housing form a stepping bearing. They are enclosed by the part of the housing. & The hunger is a good example, the body contains the joint component, and the drive unit is mounted to the bicycle frame, the joint component In particular, it is made in the form of a threaded bolt, and the thread inspection direction W is aligned along the stepping bearing. They are threaded through the through-guide side of the frame when installed. The motor unit is mounted along the pedal 安装 during installation. And the threaded bolt runs through the through hole in the bicycle frame on the same working path. In the pre-installed state, the drive unit is provided with joint members in the form of a threaded weir which extends parallel to the pedal shaft and which are used to insert the through-holes of the opposing portions of a frame and then screw them together as described above. If this is not the case, the connector element can be designed to have a through-hole shape # through which the screw can pass. These screws also pass through the through holes of the bicycle frame during installation to cause the screws to engage 'but the joint elements should be designed as threaded bolts.

There should be at least three joint elements in this unit, especially 3~1〇 or 3~6. It creates a mesh which can be screwed into the bicycle frame due to the joint element. The drive unit has a plurality of orientations to be selected toward the through hole. The bicycle frame can be provided with a connection portion ~w |~. πBei is difficult, and he is fixed. _ and *^ into a fixed drive unit The through-hole of the connecting section and the joint member of the drive (in the form of a threaded bolt) are designed to be connected to each other with the frame of the frame. The total length of the joint is from the inner bore of the m (ie m). In addition, it is possible to connect the connecting portion or the connecting portion of the connecting portion with the connecting portion, thereby simplifying the driving unit. The type (movably) is fitted to each other. Thus, the An 9 201221410 shell The body has a contour (when the projection is perpendicular to the plane perpendicular to the pedal crank axis) ), it has a rounded rectangle with a side length ratio of about 1: 1, which is the largest deviation from this value by a maximum of 25%, 15°/., 10% or 5%, so the surrounding rectangle is roughly square. In this way, the housing can be reversed for a half cycle without producing a different minimum required wheel base (Radstand, wheel base). The rectangle has two horizontal and vertical sides (if the frame or bicycle stands, And relative to the direction of gravity) - if the housing is mounted in an aligned orientation (0° or 180., also 90. or 270.) The vertical axis of the pedal crank shaft stands vertically at one point. Positioned on a side of the rectangle (the center line) (Seitenhalbierenden) and should be on a vertical center line. This point can also be placed in the attachment of the half-edge - if so the distance between the point and the half-edge is the largest The length is divided by 20〇/〇, 1〇〇/0, 5%, 3% or 2% of the side. The motor and motor linkage midpoint, the midpoint of the motor coupling, and the pedal crankshaft (or The longitudinal axis of the stepped bearing) creates a generally equilateral triangle. The difference between the length of the long side and the length of the shortest side is not more than 4〇%, 30%, 25%, 15%, 10% or 50/〇. This makes the motor rotatable. The contour drawn by the rotation is kept substantially constant, so If the drive unit is installed in a different orientation, it is not necessary to further cooperate with the bicycle frame. In addition, the motor midpoint and the driver are located on a first straight line, wherein the longitudinal axis of the pedal crankshaft is on the second straight line, wherein the first and the first The two straight lines form the enclosed rectangle into three substantially identical sections, wherein the sections formed by the division are not more than 20%, 1%, or 5%. The second straight line is parallel to the rectangle surrounded by s A horizontal edge 'and the first straight line is substantially parallel to the side of the rectangle surrounded by the δ 10 201221410, and the angle deviation is preferably at most 2 (Γ~1 (Γ, or 5. . The partial section also makes the drive unit easy to rotate without causing significant differences when installed and placed in the bicycle axle. The midpoint of the motor should correspond to the longitudinal axis of the motor shaft. The midpoint of the motor coupler corresponds to the axis of rotation of a gear that fits into the motor shaft. At least the connector element of the drive unit is arranged on the second line. One of the joints 7L of the drive unit is placed on a straight line which is perpendicular to the horizontal side of the enclosed rectangular shape and which will enclose the midpoint of the rectangle. The first portion of the housing (in which the pedal crank shaft extends) has a generally semi-circular wheel temple. The first portion of the housing is generally centered in the second portion of the body. The contour of the housing corresponds to two semicircles that are connected in parallel (in other words, a running path (four) of a magazine). Is this semicircle particularly on the side of the motor coupling? In particular, it is approximately a rectangle Ρ [in) first port | 5 is a degree equivalent to the height of the enclosed rectangle of 45% ~ 65 ° /. Or 5 5% ~ 60%. In another alternative embodiment, the first portion of the housing has an elliptical profile that is uniformly oriented (i.e., lying). The longitudinal axis of the pedal crankshaft is substantially on a line, and the first portion hits the second portion on the line. The driving unit should be installed such that when the bicycle is standing, the parallel line of the second part is perpendicular to the direction of gravity, the second part can form a lower section and is arranged under the bicycle frame, or the driving unit can be formed in the case of the installation mode of #18Qe - the upper section, which is located inside the bicycle frame. This creates different ground degrees of freedom. 201221410 In the rear wheel direction, the 仲n扣 buckle will not be in any " extra large wheel base (or 7 I stretch the same distance. Due to the possible orientation of the construction of the tight species, the rear wheel is caused by the early configuration of the drive C Distance to the pedal crankshaft). Having a rounded solid addition, the output means comprises a socket, a weir element, which is designed to secure a sprocket. The fixing element of the sprocket bearing connector for the month's J-chain gear is in the form of a hole. The fixed element fixing element can also be a through hole, and the connector can also be called a spider. The circular arrangement of the bottom, or a constant angular distance between the pieces of the sprocket. According to another feature of the invention, it utilizes the method of the Anshang to drive the drive: to the electric treadmill. A bicycle frame and a drive unit of the invention are provided, for example, by using the previous manufacturing steps. The drive unit is connected to the bicycle frame. If the drive unit is connected to the bicycle frame, the pedal crankshaft (or, the step bearing, or both) All have been integrated in the drive unit. At this time, the drive single S is only connected to the frame in a static manner, and does not need to create a dynamic connection between the frame and the pedal crankshaft. It is different from the other situation. The stepping bearing and/or the pedal crankshaft are fixed on the frame and then the remaining driver components are to be installed. The so-called bicycle frame contains at least the following two components: the lower tube, the chain raft, and the seat tube. These components are on the bicycle. A connecting portion of the frame is touched together. In this position, the prior art frame is generally provided with a stepping bearing. Since the stepping bearing (and the pedal crankshaft) is not integrated in the frame according to the invention (before the driving unit is fixed) Therefore, this position of the frame (in this position, the stepping bearing according to the invention?) is called the connecting section. It is used to mount the drive unit. The drive unit is fixed at this 12 201221410 connecting section, and the straight Congrui stays - ' ' A fixing device that is mounted to the connecting section early, with the pedal, the driver and the motor driver, all the pieces (regardless of the control device and the battery) are fixed to the frame at the same time as the driving unit is installed. There is a recess on the drive unit. When the drive unit is installed, the pedal is placed on the vehicle, and the pedal is placed on the pedal. The pedal shaft extends particularly through this section. =: The recess corresponds to the general frame. Wherein, the driving device is inserted into the recess, and the driving unit and the connecting portion are fixed to each other by a fixing member, wherein a pedal driving portion of the driving unit is disposed in the recess. At least in its outer surface, the casing is at least partially or entirely caused by a metal sheet (for example, steel or aluminum or an aluminum alloy). [Embodiment] FIG. 1 shows a lower portion of a bicycle frame, which is roughly composed of a tube (2). 〇), a chain of links (22), and a lower tube (24) composed of ^ they are struck together on the connecting section (10) of the bicycle frame, and the side of the connecting section (1〇) facing away from the frame Forming a semi-circular recess, which may be approximated by a plurality of flat sections.

The housing of the drive unit (3〇) is connected with the connecting ant (30) by a threaded bolt (4〇) (44). Since the figure is an exploded view, the joint elements are in a row and are displayed in a solid state. They fit directly into each other. Threaded bolt (4〇) (44) is screwed with 13 201221410 thread E (60) (62) (70). The latter extends from the opposite side through the connecting section of the frame to the threaded bolt (40) (44) and is embedded therein by means of a screw connection. A through hole (5〇) (54) is provided in the connecting portion (10), and the screw bolt (4〇)~(4 sentences and the screw connecting member screwed thereto are [threaded 匣 (6〇) (62) (7〇) form] extends in it. Thread 匣(60)(62)(70) is the screw connection element ' on the output side and the threaded bolt (40) (44). The screw connection element, ie the thread 匣 ( 60) (62) (70) and the threaded bolt (40) (44) form a flange connecting portion, whereby the driving unit (30) is fixed on the connecting portion (1〇), and the thread 匣 (6〇) ( 62) (7〇) has heads, which are placed on the side of the through hole (5〇) to (54) of the housing and the connecting section (1〇). Thread (匣) (60) (62) (70) a cover metal piece (74) is disposed between a side of the head and the connecting section (1〇). The fixing screw (64) (72) covers the metal piece (74) and the connecting section (10) (ie, The side of the connecting section (1〇) is in contact with the drive unit (3〇) (ie its housing) by means of a flange connection. There are three screw connections, which are threaded (40) (44), thread 匣 (60) (62) (70) and through holes (5 〇) ~ (54) formed in the figure can be seen. There is no structural disadvantage in the inner side of the connecting section, which forms a recess for the drive unit. More through holes can be formed in the connecting section than in the screw connection. This allows the drive unit to be mounted differently on the frame. The orientation of the drive unit, in particular, the drive unit can also be inverted on the head (ie, turn 180 on the position shown) on the connecting section.
