Description

Technical Field

[0001] This invention relates to the field of bicycle manufacturing technology, and more particularly to bicycle assembly brackets and lifting worktables. Background Technology

[0002] The frame is the core skeleton of a bicycle, and other components are usually directly or indirectly mounted on the frame to form a complete bicycle. When assembling a bicycle, it is usually necessary to secure the bicycle with assembly jigs before installing other components onto the frame. A conventional bicycle frame only requires a single jig for stable clamping. For example, our company's Chinese patent application with publication number CN120839730A uses a clamping unit to hold a portion of the bicycle frame, enabling the bicycle to be raised, lowered, and rotated in both horizontal and vertical planes; a single unit can complete the entire bicycle assembly. However, for longer bicycles (such as cargo bicycles), it is difficult to achieve stable clamping by only clamping a portion of the frame, let alone raising or lowering the frame. How to facilitate the assembly and unloading of such bicycles is an urgent problem to be solved. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides a bicycle assembly bracket and a lifting worktable.

[0004] This invention is achieved through the following technical solution:

[0005] The bicycle assembly bracket provided in this application includes a secondary arm, a pull rod that can move vertically relative to the secondary arm, a swing arm for supporting the bicycle frame, and an operating mechanism for user operation. The swing arm is connected to the pull rod and can move vertically relative to the secondary arm and rotate in the horizontal plane. The operating mechanism can drive the pull rod to move vertically relative to the secondary arm, and the up-and-down movement of the pull rod can drive the swing arm to switch between a first height position and a second height position.

[0006] Preferably, the auxiliary arm has a first guide member for guiding the vertical movement of the pull rod.

[0007] Optionally, the operating mechanism includes a handle and a connecting rod, one end of the handle being rotatably connected to the auxiliary arm, one end of the connecting rod being rotatably connected to the handle, and the other end of the connecting rod being rotatably connected to the upper end of the pull rod.

[0008] Optionally, the swing arm is rotatably connected to the pull rod, and the swing arm can rotate relative to the pull rod in the horizontal plane, but cannot move relative to the pull rod in the vertical plane.

[0009] Optionally, the swing arm is rotatably connected to the tie rod via a bearing.

[0010] Optionally, the bearing is installed in a bearing housing, and the lower end of the pull rod is connected to the bearing housing.

[0011] Preferably, the auxiliary arm has a second guide member for guiding the vertical movement of the bearing seat.

[0012] Optionally, a support member is installed on the swing arm.

[0013] Optionally, the support has a V-groove.

[0014] Preferably, the support member can be adjusted horizontally relative to the swing arm along the rotation center of the swing arm.

[0015] Optionally, the swing arm has a third guide member for guiding the support member to move horizontally relative to the swing arm, and the bicycle assembly bracket also includes a first locking fastener for locking the support member to the swing arm.

[0016] The bicycle assembly lifting platform provided in this application includes a base for contacting the ground, a telescopic column connected to the bottom of the base, a main arm connected to the top of the telescopic column, a clamping assembly for clamping the bicycle frame, and the bicycle assembly bracket. The telescopic column can automatically extend and retract in the vertical direction, the clamping assembly is installed on the main arm, and the auxiliary arm is connected to the main arm.

[0017] To accommodate bicycles of different lengths, the horizontal spacing between the clamping assembly and the bicycle assembly bracket is adjustable.

[0018] Optionally, the base includes a chassis with a flat bottom surface, and the bottom of the telescopic column is connected to the chassis.

[0019] To facilitate the movement of the workbench, the base also includes at least three caster assemblies mounted on the chassis. The caster assemblies include height-adjustable rollers that can switch between a third height position and a fourth height position. When the rollers are in the third height position, the bottom surface of the rollers is higher than the bottom surface of the chassis; when the rollers are in the fourth height position, the bottom surface of the rollers is lower than the bottom surface of the chassis.

[0020] To improve the stability of the bicycle assembly lifting platform and prevent it from tipping over, the base also includes at least two side supports, one end of which is connected to the chassis and the other end of which extends to the periphery of the chassis.

[0021] Compared with the prior art, this application has at least the following beneficial effects:

[0022] 1. The bracket of this application can support a part of the bicycle frame from below. When the bicycle is long, the bracket and the clamping assembly work together to stably clamp the bicycle, so as to quickly complete the assembly of the bicycle. The swing arm of the bracket is designed to be lowerable and swingable. After the assembly is completed, the swing arm is lowered away from the bicycle frame and then rotated to move away from directly under the bicycle, so as to push the bicycle away from the assembly area smoothly and easily.

[0023] 2. The workbench of this application uses a clamping component to clamp one end of the bicycle frame and a swing arm to support the other end of the bicycle frame. This can more stably fix the bicycle frame, which is conducive to subsequent assembly work and can provide great convenience for bicycle assembly / repair.

[0024] 3. The supporting part of this application can be adjusted laterally relative to the clamping component to accommodate bicycles of different lengths; the supporting part can be adjusted vertically relative to the clamping component to accommodate bicycles of different heights; the supporting part can be adjusted longitudinally relative to the clamping component to accommodate bicycles of different widths; this application can stably lift bicycles of different models at different heights and shapes, improve the efficiency of bicycle assembly or maintenance, and prevent bicycles from falling, making it safe and reliable.

[0025] Of course, implementing any of the embodiments of the present invention does not necessarily require achieving all of the advantages described above at the same time. Attached Figure Description

[0038] Please see Figures 1 to 3 This embodiment discloses a preferred bicycle assembly bracket, which includes a swing arm 1, a secondary arm 2, a pull rod 3, and an operating mechanism 4.

[0039] The auxiliary boom 2 is used to mount the entire bracket onto other components of the workbench (such as the main boom).

[0040] The swing arm 1 is used to support the bicycle frame. The swing arm 1 can move in the Z direction relative to the auxiliary arm 2, and the swing arm 1 can also rotate in the XY plane relative to the auxiliary arm 2. The Z direction is the vertical direction, and the XY plane is the horizontal plane.

[0041] The operating mechanism 4 is for manual operation by the user. The operating mechanism 4 can drive the pull rod 3 to move in the Z direction relative to the auxiliary arm 2. The up and down movement of the pull rod 3 can synchronously drive the swing arm 1 to move in the Z direction relative to the auxiliary arm 2, thereby switching the swing arm 1 between the first height position and the second height position.

[0042] To make the movement of the pull rod 3 more stable in the Z direction, in some embodiments, the auxiliary arm 2 has a first guide member. The first guide member is a member used to guide the movement of the pull rod 3 relative to the auxiliary arm 2 in the Z direction. It is worth noting that the first guide member can be any common form and structure, such as a vertical groove formed on the auxiliary arm 2 for a portion of the pull rod 3 to slide; or a first guide block 21 mounted on the auxiliary arm 2, the first guide block 21 having a vertical guide channel that matches the pull rod 3, through which the pull rod 3 passes.

[0043] Please see Figure 1 and Figure 4 In an exemplary embodiment, the auxiliary arm 2 has a mounting bracket, which includes two spaced-apart mounting plates 22. The upper ends of the two mounting plates 22 are connected together by a first pin 23, and the lower ends of the two mounting plates 22 are connected together by a first guide block 21. The two spaced-apart mounting plates 22 can be fixedly connected to the auxiliary arm 2 by fasteners.

[0044] In some embodiments, the operating mechanism 4 includes a handle 41 and a connecting rod 42. One end of the handle 41 is rotatably connected to the auxiliary arm 2, one end of the connecting rod 42 is rotatably connected to the handle 41, and the other end of the connecting rod 42 is rotatably connected to one end of the pull rod 3. (See also...) Figure 2 In an exemplary embodiment, one end of the handle 41 is connected to the first pin 23, thereby achieving a rotatable connection with the mounting bracket; one end of the connecting rod 42 is rotatably connected to the handle 41 via the second pin 44, and the other end of the connecting rod 42 is rotatably connected to the pull rod 3 via the third pin 45. Rotating the handle 41 in both directions can drive the connecting rod 42 to move in the vertical plane, thereby driving the pull rod 3 to move up and down.

[0045] In some embodiments, the handle 41 has a limiting member 46, which can limit the rotation angle of the handle 41 in the vertical plane, thereby limiting the travel of the lever 3.

[0046] In some embodiments, the swing arm 1 is rotatably connected to the pull rod 3, and the swing arm 1 can rotate relative to the pull rod 3 in the horizontal plane, but cannot move relative to the pull rod 3 in the vertical plane. Preferably, the swing arm 1 is rotatably connected to the pull rod 3 via a bearing 52.

[0047] Please see Figure 3In the exemplary embodiment illustrated, the lower end of the pull rod 3 is connected to the bearing housing 51, and the adapter 53 is rotatably connected to the bearing housing 51 via the bearing 52. The swing arm 1 is connected to the adapter 53, realizing the rotatable connection between the swing arm 1 and the pull rod 3. In some embodiments, the pull rod 3 passes through a hole in the connecting plate 56, and the pull rod 3 is threadedly connected to a first nut 54 and a second nut 55. The connecting plate 56 is located between the first nut 54 and the second nut 55, and the first nut 54 and the second nut 55 restrict the axial displacement of the connecting plate 56 on the pull rod 3. The connecting plate 56 is connected to the bearing housing 51 via a bolt assembly. In this way, when the pull rod 3 moves in the Z direction, it can drive the connecting plate 56, the bearing housing 51, and the swing arm 1 to move synchronously in the Z direction.

[0048] In some embodiments, the auxiliary arm 2 has a second guide member. The second guide member is a member for guiding the bearing housing 51 to move relative to the auxiliary arm 2 in the Z direction. It is worth noting that the second guide member can be any common form and structure, such as a vertical groove formed on the auxiliary arm 2 for a portion of the bearing housing 51 to slide. It can also be a second guide block 24 mounted on the auxiliary arm 2, the second guide block 24 having a vertical guide channel that matches the bearing housing 51, through which the bearing housing 51 can pass. The second guide member not only guides the bearing housing 51 to move in the Z direction, but also prevents the bearing housing 51 from wobbling left and right.

[0049] In some embodiments, a support member 11 is mounted on the swing arm 1, the support member 11 being used to support a portion of the frame. In some embodiments, the support member 11 has a V-groove 12, the V-groove 12 being adaptable to different sizes of frame tubes, the V-groove 12 being able to restrict the frame from sliding on the support member 11.

[0050] In some embodiments, the support member 11 can be radially adjusted relative to the swing arm 1 along the rotation center of the swing arm 1. In some embodiments, the swing arm 1 has a third guide member. The third guide member is a member for guiding the support member 11 to move horizontally relative to the swing arm 1. It is worth noting that the third guide member can be any common form and structure, such as a radial groove 14 formed on the swing arm 1 for sliding a portion of the support member 11. In an exemplary embodiment, the V-groove 12 can limit the frame from sliding radially on the support member 11 along the swing center of the swing arm 1. Of course, the bicycle assembly bracket also includes a first locking fastener for locking the support member 11 to the swing arm 1. It should be understood that when the first locking fastener is locked, the support member 11 cannot move relative to the swing arm 1, and the position of the support member 11 on the swing arm 1 is fixed. Correspondingly, when the first locking fastener is unlocked, the support member 11 is released, the support member 11 can move relative to the swing arm 1, and the position of the support member 11 on the swing arm 1 is adjustable. In an exemplary embodiment, the first locking device includes a first locking knob 13. Tightening the first locking knob 13 can lock the support member 11 and the swing arm 1; loosening the first locking knob 13 can unlock the support member 11 and the swing arm 1. This is a conventional technical means in the art and will not be described in detail here.

[0051] In some embodiments, the swing arm 1 includes a horizontal arm and a vertical arm, the vertical arm being rotatably connected to the tie rod 3, and a support member 11 mounted on the horizontal arm. Furthermore, the support member 11 is adjustable in position along the length of the horizontal arm. In some embodiments, the horizontal arm and the vertical arm are manufactured integrally. In other embodiments, the horizontal arm and the vertical arm are manufactured separately and then joined together. In the illustrated exemplary embodiment, both the horizontal arm and the vertical arm are profiles, connected together by a corner plate.

[0052] Of course, to facilitate the connection of the auxiliary arm 2 to other components of the worktable, a connecting member is attached to the auxiliary arm 2. In some embodiments, the connecting member can be adjusted vertically in the Z direction relative to the auxiliary arm 2. This allows adjustment of the height difference between the swing arm 1 and other components to accommodate bicycles of different heights. Preferably, the auxiliary arm 2 has a fourth guide member. The fourth guide member is a member used to guide the movement of the connecting member relative to the auxiliary arm 2 in the Z direction. It is worth noting that the fourth guide member can be any common form and structure, such as a vertical groove 25 formed on the auxiliary arm 2 for a portion of the connecting member to slide.

[0053] Of course, the connecting component also includes a second locking fastener for locking the connecting component to the auxiliary arm 2. It should be understood that when the second locking fastener is tightened, the connecting component cannot move relative to the auxiliary arm 2, and the position of the connecting component on the auxiliary arm 2 is fixed. Correspondingly, when the second locking fastener is unlocked, the connecting component is released, and the connecting component can move relative to the auxiliary arm 2, and the position of the connecting component on the auxiliary arm 2 is adjustable. In some embodiments, the second locking fastener includes a second locking knob 26. Tightening the second locking knob 26 locks the connecting component to the auxiliary arm 2; loosening the second locking knob 26 unlocks the connecting component from the auxiliary arm 2. This is a conventional technique in the art and will not be described in detail here. In an exemplary embodiment, the second locking knob 26 is located in a vertical groove 25; when the second locking knob 26 is loosened, the auxiliary arm 2 can move vertically relative to the second locking knob 26.

[0054] Please see Figures 5 to 7 This embodiment discloses a preferred lifting platform for bicycle assembly, including a base 8, a telescopic column 7, a main arm 6, a clamping assembly 9, and the aforementioned bicycle assembly bracket. The bicycle assembly bracket has already been described above and will not be repeated here. The clamping assembly 9 can be either an external clamping type or an internal tensioning type; those skilled in the art can choose according to their needs.

[0055] The base 8 is used to contact the ground to support the entire bicycle assembly lifting platform and the bicycle. The bottom of the telescopic column 7 is connected to the base 8. With the stable support of the base 8, the telescopic column 7 can stably remain upright and can stably extend and retract automatically in the Z direction. It should be understood that although the extension and retraction direction of the telescopic column 7, the movement direction of the pull rod 3, and the adjustment direction of the connecting component on the auxiliary arm 2 are all in the Z direction, this does not mean that they are coincident directions; they can also be parallel directions. In the exemplary embodiment, the extension and retraction direction of the telescopic column 7, the movement direction of the pull rod 3, and the adjustment direction of the connecting component on the auxiliary arm 2 are parallel directions to each other.

[0056] The main boom 6 is connected to the top of the telescopic column 7. The clamping assembly 9 and the bicycle assembly bracket are mounted on the main boom 6. The telescopic column 7 enables the main boom 6, clamping assembly 9, and bicycle assembly bracket to move synchronously up and down in the Z direction. The lifting height of the bicycle frame 10 can be adjusted via the telescopic column 7 for user operation and easy unloading after assembly. It is worth noting that the telescopic column 7 is an automatic telescopic mechanism, such as an electric cylinder, pneumatic cylinder, or hydraulic cylinder. Of course, the telescopic column 7 is equipped with a control unit, which controls the raising and lowering of the telescopic column 7. This is conventional technology in the field and will not be elaborated here.

[0057] Specifically, the auxiliary arm 2 of the bicycle assembly bracket is connected to the main arm 6. When the main arm 6 is raised and lowered by the telescopic column 7, the clamping assembly 9 and the bicycle assembly bracket can move synchronously with the main arm 6 in the Z direction. The clamping assembly 9 can clamp a certain part of the bicycle frame 10, and the swing arm 1 of the bicycle assembly bracket can support another part of the bicycle frame 10. Through the cooperation of the clamping assembly 9 and the swing arm 1, the bicycle frame 10 can be stably maintained in the suspended state.

[0058] In some embodiments, the distance between the clamping assembly 9 and the bicycle assembly bracket in the X direction is adjustable, wherein the X direction is a horizontal axis perpendicular to the Z direction. This allows the bicycle assembly lifting platform to accommodate the assembly of bicycles of different lengths. Specifically, in some embodiments, the bicycle assembly bracket can be adjusted in position relative to the main arm 6 in the X direction. When the position of the clamping assembly 9 on the main arm 6 is fixed, the distance between the clamping assembly 9 and the bicycle assembly bracket can be adjusted by adjusting the position of the bicycle assembly bracket on the main arm 6 to meet the assembly / repair needs of bicycles of different specifications.

[0059] Please see Figure 5 In some embodiments, the main arm 6 has a fifth guide member, and the connecting component includes a carriage 61 mounted on the main arm 6. The fifth guide member is a member for guiding the carriage 61 to move in the X direction; in other words, the direction of movement of the bicycle assembly bracket in the X direction is defined by the guiding direction of the fifth guide member. It is worth noting that the fifth guide member can be of any common form and structure, for example, it can be a transverse groove 62 formed on the main arm 6 for a portion of the carriage 61 to slide. The secondary arm 2 of the bicycle assembly bracket is connected to the carriage 61, and the carriage 61 can slide on the main arm 6 in the X direction. Naturally, the bicycle assembly bracket can also move relative to the main arm 6 in the X direction, thereby achieving lateral position adjustment of the bicycle assembly bracket. Of course, the carriage 61 has a locking fastener for locking the carriage 61 to the main arm 6. It should be understood that when the locking fastener is tightened, the carriage 61 is locked, the carriage 61 cannot slide on the main arm 6, and the lateral position of the bicycle assembly bracket on the main arm 6 is fixed. Correspondingly, when the locking mechanism is unlocked, the slide 61 is released and can slide laterally on the main arm 6, allowing the lateral position of the bicycle assembly bracket on the main arm 6 to be adjusted. Preferably, the main arm 6 is substantially parallel to the X-direction. In some embodiments, the main arm 6 is a profile.

[0060] Please see Figure 3In the illustrated exemplary embodiment, the carriage 61 includes a carriage body and a first slider slidably connected to the fifth guide member. The first slider is installed in and clearance-fitted with the transverse groove 62. A second locking knob 26 passes through the carriage body and connects to the first slider. Tightening the second locking knob 26 simultaneously locks the carriage 61 to the main arm 6 and the auxiliary arm 2 to the carriage 61, thus fixing the transverse position of the carriage 61 and the height of the auxiliary arm 2. In other embodiments, spaced locking holes are provided on the main arm 6, and the second locking knob 26 is inserted into the corresponding locking holes to lock the carriage 61 in that position. Those skilled in the art can select the locking method and corresponding locking structure of the carriage 61 as needed. This application is only illustrative and does not impose any limitations.

[0061] In some embodiments, the carriage 61 further includes a second slider slidably connected to the fifth guide member. The second slider and the first slider are slidably connected to different fifth guide members, and the second slider can be locked by a third locking knob 63. When it is necessary to unlock the carriage 61, the second locking knob 26 and the third locking knob 63 need to be loosened. It is worth noting that the number of fifth guide members, the first slider, and the second slider can be reasonably set as needed.

[0062] As described above, the bicycle assembly bracket can be adjusted in position on the main arm 6. However, the invention is not limited to this. For example, in some embodiments, the position of the bicycle assembly bracket on the main arm 6 is not adjustable, while the position of the clamping assembly 9 on the main arm 6 is adjustable. In other embodiments, both the bicycle assembly bracket and the clamping assembly 9 are adjustable in position on the main arm 6.

[0063] Since the bicycle assembly lifting platform in this embodiment is placed directly on the ground via its base 8, and most production workshop floors are painted, to avoid damaging the ground by using screws to fix the base 8, in an exemplary embodiment, the base 8 includes a circular chassis 81 with a flat bottom surface. The bottom of the telescopic column 7 is connected to the chassis 81, and the large contact area between the chassis 81 and the ground increases the friction between them, so that the position can be fixed by the weight of the equipment itself.

[0064] Furthermore, due to the considerable weight of the bicycle assembly lifting platform, it is designed for easy movement. Please refer to [link / reference needed]. Figure 5In some embodiments, the base 8 further includes at least three caster assemblies 82, which are mounted on the chassis 81. Each caster assembly 82 includes height-adjustable rollers, meaning the rollers can be adjusted vertically relative to the chassis 81. The rollers can switch between a third height position and a fourth height position. When the rollers are in the third height position, the bottom surface of the rollers is higher than the bottom surface of the chassis 81; when the rollers are in the fourth height position, the bottom surface of the rollers is lower than the bottom surface of the chassis 81. The lifting structure and control method of the rollers are conventional techniques in the art, and those skilled in the art can design them reasonably as needed, which will not be elaborated here.

[0065] In this embodiment, the working principle of the base 8 switching between movable and fixed states is as follows: Assuming that in the initial state, the rollers are at the third height position, the bottom surface of the chassis 81 is in contact with the ground, the bottom surface of the rollers is higher than the bottom surface of the chassis 81, and the rollers are not in contact with the ground, the bicycle assembly lifting platform is fixed to the ground by its own weight. When the rollers are lowered, the chassis 81 is lifted off the ground by the reaction force, the friction between the chassis 81 and the ground is released, and the rollers descend to the fourth height position. Multiple rollers replace the chassis 81 in contact with the ground, at which point the entire bicycle assembly lifting platform can be easily moved. After the bicycle assembly lifting platform has moved to the predetermined position, the rollers are raised to the third height position, the chassis 81 re-contacts the ground, and the position is fixed by the weight of the equipment. Moreover, slippage between the chassis 81 and the ground is not likely, resulting in good stability and safe use.

[0066] If the bicycle is particularly long, the workbench may tilt if operated improperly or in case of an accident. In some embodiments, the base 8 also includes at least two side supports 83, one end of which is connected to the chassis 81, and the other end of which extends to the periphery of the chassis 81 and is used to contact the ground, thereby increasing the stability of the support. It is worth noting that the number of side supports 83 is reasonably set as needed.

[0067] This embodiment discloses a preferred method of using a bicycle assembly lifting platform:

[0068] First, the user adjusts the lateral distance and height difference between the swing arm 1 and the clamping assembly 9 according to the bicycle model (width, height, length), and simultaneously adjusts the position of the support member 11; rotates the operating handle 41 to position the swing arm 1 at the third height position; and rotates the swing arm 1 along the horizontal plane to the working position to support the frame 10. In some embodiments, the swing arm 1 is parallel to the Y direction, which is the longitudinal direction perpendicular to the X and Z directions.

[0069] Then, the telescopic column 7 is shortened by the control unit, so that the main arm 6, clamping assembly 9 and swing arm 1 are lowered to the appropriate position;

[0070] Subsequently, the user places one end of the frame 10 into the V-groove 12 of the support member 11 and clamps the other end of the frame 10 with the clamping assembly 9. The support member 11 can restrict the frame 10 from swaying in the Y direction relative to the swing arm 1. The frame 10 can be firmly held by the bracket and the clamping assembly 9.

[0071] Then, the telescopic column 7 is extended by the control unit, so that the frame 10 is raised to a suitable height so that other parts of the bicycle can be installed on the frame 10.

[0072] After the complete vehicle assembly is completed, the telescopic column 7 is shortened by the control unit, allowing the bicycle to descend to a suitable height and releasing the clamping assembly 9, so that the wheels can touch the ground. The user then turns the handle 41 to lower the lever 3 to a predetermined position. At this time, the swing arm 1 descends to the second height position simultaneously, so that the swing arm 1 and the bicycle are at a certain distance in the vertical direction. After that, the user can easily rotate the swing arm 1 in the horizontal plane to be directly below the bicycle, so that the swing arm 1 will not obstruct the bicycle. The user can then easily push the bicycle away from the assembly area to facilitate the assembly of the next bicycle.

[0073] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
