Description

[Technical Field]

[0001] This invention relates to a frame assembly and a bicycle comprising the frame assembly. [Previous Technology]

[0002] Bicycles with full suspension (such as electric bicycles) are known to us. Here, the bicycle frame has a main frame and a rear end equipped with springs. The rear end is generally rotatable relative to the main frame at the main pivot point. In the case of electric bicycles, additional space is required, and the drive unit connected to the main frame is located in the area of ​​the bottom bracket bearing shaft. The space requirements of the drive assembly and the location of the main pivot point often conflict. [Summary of the Invention]

[0003] In contrast, the advantage of the frame assembly according to the invention, having the features of claim 1, lies in the simplified construction and improved kinematics achieved in the bicycle frame with suspension. According to the invention, this is achieved by a frame assembly comprising a main frame, a spring-loaded rear end, and at least one connecting element. Here, the connecting element is arranged on the main frame. Here, the connecting element connects at least a portion of the rear end to the main frame so that it can pivot about a hinge axis. Furthermore, the connecting element is specified for securing the drive unit to the main frame, specifically, to the hinge axis.

[0004] In other words, the frame assembly has an interface with the connecting elements, which enables a pivotal connection between at least a portion of the rear end and the main frame, and simultaneously enables the drive unit to be secured to the main frame.

[0005] This means that the connecting element simultaneously and in the same location (specifically, on the hinge axis) performs both the functions of pivotable connection and fastening interface. Therefore, the connecting element simultaneously forms a pivot point and a fastening point. The connecting element can be better regarded as a joint that, in addition to pivotally connecting the main frame and the rear portion, also allows the drive unit to be fastened to the main frame.

[0006] Many advantages can be obtained by unifying the fastening points of the drive unit and the pivot points between at least a portion of the main frame and the rear section. Therefore, specifically, the frame assembly provides a particularly space-saving and cost-effective construction in the bearing area of ​​the bicycle's bottom bracket. Since the connecting elements simultaneously establish the hinge function between the main frame and the rear section and the fastening function for the drive unit, cost savings can be achieved by omitting other fastening and / or hinge elements. Similarly, holes in the main frame for other fastening and / or hinge elements of this type can be avoided, which, for example, has an advantageous effect on the main frame rigidity. Furthermore, more space in the main frame is available for the connecting elements, allowing for optimal placement of these elements. Specifically, optimal self-induction and kinematic angles allow for greater design freedom. Additionally, the increased available space is advantageous in terms of the increased available space for installing, for example, the cables and conduits of the drive unit. In addition, a shorter chainstay can be implemented at the rear, on the one hand, to allow for a more targeted or flexible influence on the bicycle's driving characteristics over a wider range, and on the other hand, to allow for a particularly flexible adjustment of the bicycle's geometry, especially in cases with a smaller frame size.

[0007] The appendix contains preferred modifications of the present invention.

[0008] Preferably, the rear end has a spring element, wherein at least one connecting element pivotally connects the main frame and the spring element to each other so as to allow pivoting about a hinge axis. This means that in this configuration, the connecting element forms a support for one side of the spring element. Preferably, the other side of the spring element is connected to other parts of the rear end, such as to a deflecting rocker arm connected to the rear upper fork of the rear end. The connecting element thus allows for a pivotable connection between the spring element and the main frame. Therefore, a particularly cost-effective, simple, and space-saving construction of the spring accessory can be achieved.

[0009] Particularly preferably, the rear end has a rear frame, wherein at least one connecting element connects the main frame and the rear frame to each other so as to pivot about a hinge axis. Preferably, for example, the rear frame is formed by chainstays and upper forks, and other elements pivotable relative to the main frame. Preferably, here, the connecting element forms a main hinge by means of which the rear frame can pivot relative to the main frame. Thus, a particularly flexible configuration in terms of kinematics, specifically, in terms of riding dynamics, can be provided for the bicycle in association with the cost-effective and space-saving construction of the main hinge. Particularly preferably, two connecting elements can be provided that connect the spring elements and the rear frame to the main frame so as to pivot about a separate hinge axis in each condition. Here, each of the two connecting elements can be additionally designated for securing the drive unit to the main frame. Here, preferably, the drive unit can be exclusively secured to the main frame by means of these two connecting elements. Therefore, a particularly simple, cost-effective, and space-saving construction of the frame components can be provided. Alternatively, for example, another connection point can be provided for fastening the drive unit to the main frame, for example, by means of screws.

[0010] Preferably, the frame assembly further includes a drive unit, which is fastened to the main frame by means of at least one connecting element. Preferably, the drive unit has a motor and / or transmission device. Here, specifically, the drive unit is fixedly connected to the main frame such that no relative rotation occurs between the drive unit and the main frame. Preferably, specifically, the frame assembly has a total of two or three connecting elements by means of which the drive unit is fastened to the main frame. Thus, a particularly simple and robust assembly can be provided. Preferably, the drive unit has a bottom bracket bearing such that the bottom bracket bearing shaft passes specifically through the drive unit.

[0011] Preferably, the drive unit is at least partially disposed between the two frame walls of the main frame. For example, the drive unit may be disposed such that it is substantially entirely located between the two frame walls, so that the frame walls provide mechanical protection for the drive unit. Alternatively, for example, only one fastening area of ​​the drive unit may be disposed between the two frame walls, such that the drive unit is disposed such that it is substantially free to be located outside the main frame.

[0012] Preferably, the connecting element further includes a through bolt that extends along the hinge axis through the main frame and the drive unit. This provides a particularly simple and cost-effective construction for the frame assembly. Furthermore, for example, because the through bolt can be pushed into the aligned through holes of the drive unit and the main frame from one side, assembly is particularly simple, requiring only entry from this side. Here, preferably, the through bolt for fixing is screwed onto nuts on opposite sides. Particularly preferably, the drive unit is fastened to the main frame by a total of two through bolts.

[0013] Preferably, the connecting element has two fastening screws, which, in each case, extend along the hinge axis, and the main frame and drive unit are screwed together by means of these fastening screws. Specifically, the two fastening screws are screwed into the drive unit and the main frame from opposite sides. For example, when the drive unit is partially arranged between two frame walls of the main frame, in each case, the two fastening screws can be screwed into the drive unit through one of the frame walls to achieve a fixed connection between the main frame and the drive unit. Preferably, the drive unit and the main frame are screwed together by a total of four fastening screws or a total of six fastening screws. Particularly preferably, it is also possible to use a combination of fastening screws and through bolts to fasten the drive unit.

[0014] Particularly preferably, the drive unit has two fastening lugs. For example, the fastening lugs may be configured to protrude from the housing of the drive unit. By means of the fastening lugs, the drive unit is fastened to the main frame by means of connecting elements. The rear swing arm region is arranged between the two fastening lugs in this configuration. Here, the integrated, lower, and front regions of the rear end where the two rear lower forks converge are considered as the swing arm region. Here, specifically, the connection between the rear end and the main frame is made indirectly by means of the drive unit. Here, preferably, the swing arm region and the drive unit are connected to each other so that they can pivot about a hinge axis by means of connecting elements.

[0015] Preferably, the rear end has two rear lower forks that are hingedly connected to the main frame by means of a connecting element. This means that in the area of ​​the interface between the main frame, the drive unit, and the rear end, two separate rear lower forks are provided that are connected to the main frame by means of a connecting element in each case. For example, a single through bolt can be provided here as the connecting element. Alternatively, each rear lower fork can be connected to the main frame by means of separate fastening screws, wherein the two fastening screws are located on a common hinge axis.

[0016] Preferably, each of the two rear lower forks is arranged about the hinge axis between the drive unit and one of the two frame walls of the main frame. This means that the two rear lower forks connected to the drive unit are at least partially located within the socket space of the main frame defined by the two frame walls.

[0017] Preferably, the drive unit and the two frame walls are further arranged between the two rear lower forks in the direction about the hinge axis. In other words, the two rear lower forks are arranged outside the main frame in the direction about the hinge axis.

[0018] Preferably, the connecting element has at least one bearing, specifically a ball bearing or friction bearing, arranged between at least a portion of the main frame and the rear end. Preferably, the connecting element has at least two bearings to obtain stable mechanical support. Specifically, in each case, one bearing is arranged between each of the two frame walls and each rear lower fork or swing arm area.

[0019] The present invention further relates to a bicycle comprising the described frame assembly. Preferably, the bicycle is a bicycle capable of being operated by muscle power and / or electric power, and more particularly, an electric bicycle. Here, specifically, this is an electric bicycle with full suspension. Due to the connecting elements of the special frame assembly acting as the main hinge and simultaneously forming the fastening interface of the drive unit, a particularly space-saving arrangement of various components can be achieved in the area of ​​the bottom bracket bearing axle. Here, specifically, the electric bicycle can be geometrically constructed from the perspective of optimal kinematics and riding dynamics. Here, the frame assembly can be particularly preferably constructed such that the connecting elements are arranged at a height level between the bicycle chain and the chain link arranged on the bottom bracket bearing. Here, the hinge axle is preferably located on or near the chain link. Here, the point from the chain link to the bicycle chain where the rider applies manual propulsion force is considered the chain link.

[0020] Preferably, the frame assembly includes a drive unit fastened to the main frame by means of at least one connecting element. Here, the at least one connecting element is arranged on the rearward region of the drive unit along the direction of travel, preferably at the rearward end along the direction of travel. This means that the drive unit extends substantially forward along the direction of travel from the connecting element. Therefore, a particularly space-saving assembly can be provided so that the suspension system can be optimally arranged and the geometry of the frame assembly can be optimally adjusted from a kinematic and dynamic perspective.

Implementation Method

[0029] Figure 1 shows a simplified schematic diagram of a bicycle 10 according to a first exemplary embodiment of the present invention. The bicycle 10 is an electric bicycle that can be operated by muscle power and / or electric power.

[0030] Here, the bicycle 10 has a frame assembly 1, which has a drive unit 5, which has an electric motor and a transmission device and is constructed to support the pedaling force of the cyclist by means of electric power. The bicycle 10 for supplying power to the drive unit 5 may have a battery (not shown).

[0031] Here, the bottom bracket bearing 14 of the bicycle 10 is part of the drive unit 5. The bottom bracket bearing 14 is provided for connecting the crank and pedals (not shown in the figure).

[0032] The bicycle 10 is a fully suspended bicycle with a suspension fork 11 and a rear end 3 equipped with springs.

[0033] After the spring is installed, the rear end 3 has a rear end frame 7, which is connected to the main frame 2 of the frame assembly 1 of the bicycle 10 so that it can pivot about the hinge axis 40. Here, the hinge axis 40 is perpendicular to the drawing plane of FIG1.

[0034] Here, in detail, the rear frame 7 has a rear lower fork 32 and a rear upper fork 33 arranged at acute angles to each other. The main frame 2 preferably has an upper tube 21, a lower tube 22 and a seat bracket 23, which are similarly arranged in a substantially triangular shape.

[0035] Furthermore, the rear end 3 has a spring element 6 and a deflection arm 8. Here, in each condition, the spring element 6 is hinged to the deflection arm 8 and the main frame 2. In addition, the deflection arm 8 is hinged to the upper end of the rear end frame 7, specifically, to the rear upper fork 33. Furthermore, the deflection arm 8 is hinged to the seat bracket 23.

[0036] To achieve a pivotable connection between the main frame 2 and the rear frame 7, the frame assembly 1 includes a connecting element 4 disposed on the main frame 2. The connecting element 4 can therefore be considered as the main articulation of the bicycle 10's suspension. Here, the connecting element 4 is further specified for securing the drive unit 5 to the main frame 2. This means that the connecting element 4 fulfills two functions: hingedly connecting the rear frame 7 and the main frame 2 to each other, and simultaneously securing the drive unit 5 to the main frame 2.

[0037] Here, the connecting element 4 forms a connection point between the drive unit 5 and the main frame, and the connection point is arranged in the area of ​​the drive unit 5 located at the rear along the travel direction 15 of the bicycle 10.

[0038] Here, the unification of the fastening point and pivot point provides many advantages. Specifically, this achieves a particularly space-saving construction of the frame assembly 1 in the area of ​​the drive unit 5. As a result, particularly since the connecting element 4 and therefore the hinge shaft 40 can be arranged particularly close to the axis of the bottom bracket bearing 14, optimal bicycle kinematics from the perspective of riding dynamics is achieved. Here, the hinge shaft 40 is preferably located at the chain engagement point between the bicycle chain and the chain link 16 of the bicycle 10. Here, the chain engagement point is located vertically above the bottom bracket bearing 14 and on or near the outer circumference of the chain link 16. Furthermore, the unification of the main pivot point of the frame assembly 1 and the fastening point of the drive unit 5 allows for weight and cost savings, as fastening components can be omitted, for example.

[0039] In the first exemplary embodiment of FIG1, the drive unit 5 is fixedly connected to the main frame 2 at a total of two fastening points. The first fastening point is formed by the connecting element 4, and the second fastening point is formed by the fastening member 55 on the front region of the drive unit 5 along the travel direction 15. For example, the second fastening member may be a screw fitting by means of a through bolt and / or by means of one or more screws.

[0040] A more specific design embodiment of the connection between the main frame 2, the rear frame 7, and the drive unit 5 via the connecting element 4 will be described in detail below with reference to FIG. 2. Here, FIG. 2 shows a detailed cross-sectional view of the bicycle 10 of FIG. 1 in the area of ​​the connecting element 4.

[0041] As shown in Figure 2, the drive unit 5 is partially arranged inside the main frame 2, specifically between the two frame walls 21 of the main frame 2. The two rear lower forks 32 of the rear tail 3 are arranged outside the main frame 2 about the hinge axis 40.

[0042] Here, the connecting element 4 has a through bolt 41 that extends along the hinge axis 40 through the main frame 2, the drive unit 5, and the two rear lower forks 32. Here, the through bolt 41 provides a particularly simple, cost-effective, and stable connection between the drive unit 5 and the main frame 2.

[0043] The through bolt 41 has a bolt head 41a, which can be supported on the right rear lower fork 32 in FIG2. In addition, the through bolt 41 has a nut 41b, which can be supported on the opposite side on the left rear lower fork 32 and can be screwed into the bolt area 44 of the through bolt 41 to secure the through bolt 41.

[0044] To facilitate the connection between the main frame 2 and the rear tail section 3, which is pivotable about the hinge axis 40, in each case, a bearing 43 is arranged between each of the rear forks 32 of the rear tail section 3 and the through bolt 41. The bearing 43 is exemplarily illustrated as a ball bearing. Alternatively, the bearing 43 may also be constructed as a friction bearing or the like.

[0045] The frame assembly 1 in the region of connecting element 4 further includes a spacer sleeve 45 and a tolerance compensation element 46. The spacer sleeve 45 is arranged between the right rear lower fork 32 and the right frame wall 21, and between the right frame wall 21 and the drive unit 5, in each case. The tolerance compensation element 46 is constructed in the form of a sleeve, arranged outside the bolt area 44 of the through bolt 41 and between the bolt area 44 and the left frame wall 21. Furthermore, the tolerance compensation element 46 is arranged between the drive unit 5 and the left rear lower fork 32. Here, the spacer sleeve 45 and the tolerance compensation element 46 achieve optimal geometry adjustment of the frame assembly 1 in a particularly simple and cost-effective manner.

[0046] FIG3 shows details of a cross-sectional view of a bicycle 10 according to a second exemplary embodiment of the present invention, which is similar to the cross-sectional view of FIG2. The second exemplary embodiment substantially corresponds to the first exemplary embodiment of FIG1 and FIG2, except for the alternative arrangement of the bearing 43. In the second exemplary embodiment of FIG3, the bearing 43 is arranged between the bolt region 44 of the through bolt 41 and the frame wall 21. Therefore, an alternative advantageous construction and alternative advantageous kinematics can be provided for the frame assembly 1.

[0047] Figure 4 shows details of a cross-sectional view of a bicycle 10 according to a third exemplary embodiment of the present invention, which is similar to the cross-sectional view of Figure 2. The third exemplary embodiment substantially corresponds to the first exemplary embodiment of Figures 1 and 2, except that the connecting element 4 has two fastening screws 42 instead of through bolts 41. In each case, the two fastening screws 42 are screwed from the outside along the hinge axis 40 into the assembly consisting of the chainstay 32, the frame wall 21, and the drive unit 5. Here, the two fastening screws 42 are fixedly screwed into the drive unit 5. In each case, the bearing 43 is located between each fastening screw 42 and each respective chainstay 32.

[0048] Furthermore, the spacer sleeve and tolerance compensation element are not provided in the third exemplary embodiment. In fact, these elements are screwed together so that during assembly, the lower fork 32 is pulled onto the main frame 2 by means of the fastening screws 42, thereby tightening the drive unit 5. However, alternatively, the spacer sleeve and tolerance compensation element can be provided in a manner similar to that shown in FIG. 2. Here, according to the third exemplary embodiment of FIG. 4, the connecting element 4 with two fastening screws 42 provides another particularly cost-effective, simple, and space-saving connection possibility.

[0049] FIG. 5 shows details of a cross-sectional view of a bicycle 10 according to a fourth exemplary embodiment of the present invention, which is similar to the cross-sectional views of FIGS. 2 to 4. The fourth exemplary embodiment substantially corresponds to the first exemplary embodiment of FIGS. 1 and 2, except that the chainstays 32 are arranged within the main frame 2. Specifically, the two chainstays 32 are arranged between one of the drive unit 5 and the frame wall 21 in each case. In a manner similar to the third exemplary embodiment of FIG. 4, the connecting element 4 in the fourth exemplary embodiment has two fastening screws 42 screwed into the drive unit 5. As shown in FIG. 5, tolerance compensation by means of spacer sleeves and / or tolerance compensation elements is also preferably not provided in the fourth exemplary embodiment. However, in alternative embodiments, the bicycle of the fourth exemplary embodiment may also be equipped with spacer sleeves and / or tolerance compensation elements.

[0050] FIG. 6 shows details of a cross-sectional view of a bicycle 10 according to a fifth exemplary embodiment of the present invention. The fifth exemplary embodiment substantially corresponds to the first exemplary embodiment of FIG. 1 and FIG. 2, but has an alternative arrangement for the frame wall 21, drive unit 5, and rear end 3. In the fifth exemplary embodiment of FIG. 6, the drive unit 5 has two fastening lugs 51 by means of which the drive unit 5 is fastened to the main frame 2 by means of connecting elements 4. Specifically, the fastening lugs 51 protrude into the insertion space between the two frame walls 21, wherein the rest of the drive unit 5 is arranged externally. Here, each fastening lug 51 is screwed onto the respective frame wall 21 by means of a fastening screw 42.

[0051] The swing arm region 31 of the rear end 3 is arranged between two fastening lugs 51. Here, the swing arm region 31 corresponds to an integral region located at the front end of the rear end frame 7 along the travel direction 15 (see FIG. 1), and the two rear lower forks 32 converge toward this region. Here, the pivotable fastening of the swing arm region 31 to the main frame 2 is indirectly performed by the drive unit 5. For this purpose, the two fastening screws 42 have a preferred threadless connection region 42a in each condition, which extends into the swing arm region 31. Here, each bearing 43 is located between each connection region 42a and the swing arm region 41.

[0052] FIG7 shows a simplified schematic diagram of a bicycle 10 according to a sixth exemplary embodiment of the present invention. The sixth exemplary embodiment substantially corresponds to the first exemplary embodiment of FIG1 and FIG2, wherein the connecting element 4', rather than the rear frame 7, connects the spring element 6 and the main frame 2 to each other so that they can pivot about another hinge axis 40'. As with the first exemplary embodiment of FIG1, here, the connecting element 4' simultaneously acts as a hinge for the hinged connection between the spring element 6 and the main frame 2, and as a fastening member for securing the drive unit 5 to the main frame 2.

[0053] Here, the bicycle 10 in the sixth exemplary embodiment has a total of two fastening points for the drive unit 5, specifically the connecting element 4' and the fastening member 55 between the main frame 2 and the front region of the drive unit 5. Here, in the bicycle 10 illustrated in FIG7, the hinge identified by reference numeral 9 serves only as a hinged connection between the rear frame 7 and the main frame 2 around the main hinge axis 90.

[0054] The connecting element 4' is preferably constructed according to the two variants described, thus having a through bolt or having two fastening screws. Preferably, the drive unit 5 can also be fastened by means of both the through bolt and the fastening screws.

[0055] It should also be noted that the described exemplary embodiments can be combined with each other in any manner. Therefore, it is particularly preferred that the first and sixth exemplary embodiments be combined with each other so that, in each case, connecting elements are used on the main hinges between the rear frame 7 and the main frame 2 and between the spring element 6 and the main frame 2, such connecting elements simultaneously achieving a hinged connection and securing the drive unit 5. Here, in detail, only these two fastening points may be provided to secure the drive unit 5 to the main frame 2, or alternatively, it may be constructed to secure it at a total of three fastening points, for example, by means of fastening members 55 further illustrated in Figures 1 and 7.
