Abstract
Description
Technical Field
[0001] This invention relates to the field of bicycle production equipment technology, and in particular to a bicycle inverted trial assembly fixture. Background Technology
[0002] Bicycles (including e-bikes) often employ inverted installation during the R&D, prototyping, and production stages. This requires inverting the frame before installing various components. In mass production, precise tooling can be developed for a specific frame model or vehicle to secure the inverted frame. However, during the R&D and prototyping stage, because the frame and related components are not yet finalized and adjustments are necessary, the frame is typically inverted using existing round hole structures or separately added sleeves, placed on a single vertical stepped post without any protective measures. This results in instability in the front and rear center of gravity during installation, easily causing deformation of the frame's placement position. Consequently, some prototyping problems cannot be effectively detected, leading to situations where trial production is normal but problems persist during mass production. Summary of the Invention

Detailed Implementation
[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0019] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.
[0020] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0021] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0022] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted.

[0024] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0025] This invention provides a bicycle inverted trial assembly fixture, such as... Figure 1 and Figure 3 As shown, it includes: a base 100; a rotating connecting frame 200, which is rotatably connected to the base 100 horizontally, and a first locking mechanism 210 is provided between the rotating connecting frame 200 and the base 100; a flipping frame 300, which is flip-connected to the rotating connecting frame 200, and a second locking mechanism 310 is provided between the flipping frame 300 and the rotating connecting frame 200; a horizontal adjustment assembly, including a horizontal adjustment roller 410 and a horizontal adjustment arm 420, the horizontal adjustment roller 410 being connected to the horizontal adjustment arm 420, and the horizontal position of the horizontal adjustment arm 420 being adjustablely connected to the flipping frame 300; and a vertical adjustment assembly, including a vertical adjustment roller 510 and a vertical adjustment arm 520, the vertical adjustment roller 510 being connected to the vertical adjustment arm 520, and the vertical position of the vertical adjustment arm 520 being adjustablely connected to the flipping frame 300.
[0026] exist Figure 1 and Figure 3 In the process, the bicycle inverted trial assembly fixture is fixed in a state suitable for trial assembly and installation.
[0027] In the bicycle inverted trial assembly fixture provided in this embodiment, the base 100, rotating connecting frame 200, and flipping frame 300 cooperate to realize horizontal rotation and vertical flipping operations, which facilitates the adjustment of the bicycle's state. The flipping mechanism also facilitates the loading and unloading of the bicycle. The first locking mechanism 210 and the second locking mechanism 310 are used to lock the rotation and flipping respectively, to prevent accidental rotation and flipping during use.
[0028] The horizontal adjustment roller 410 and the vertical adjustment roller 510 work together to provide two support positions for the frame, which can improve the stability of the frame when it is placed upside down. The horizontal adjustment component and the vertical adjustment component are used to adjust the position of the horizontal adjustment roller 410 and the vertical adjustment roller 510 respectively, so that they can be adapted to various sizes of bicycles and have a wide range of applications.
[0029] like Figure 1 and Figure 3 As shown, the vertical adjusting arm 520 can be provided with a set of mounting holes. The flip frame 300 can be provided with a sleeve to receive the vertical adjusting arm 520. The sleeve and the vertical adjusting arm 520 are fixed together by bolts or other mechanisms. The vertical position of the vertical adjusting arm 520 can be adjusted by adjusting the position of the mounting holes. Meanwhile, the horizontal adjusting arm 420 is inclined and has a set of angled mounting holes. The flip frame 300 has an angled sleeve to receive the horizontal adjusting arm 420. Similarly, the horizontal position of the horizontal adjusting arm 420 can be adjusted by adjusting the position of the mounting holes. However, because the bicycle frame includes a crossbeam and a diagonal beam, the horizontal adjusting arm 420 adjusts not only the horizontal position but also the vertical position simultaneously. Therefore, it uses an inclined adjustment method instead of a horizontal one.
[0030] Preferred, such as Figure 1 and Figure 2 As shown, the first locking mechanism 210 includes a first locking tongue 212 fixed on the rotating connecting frame 200 and a first locking buckle 211 fixed on the base 100. In the locked state, the first locking buckle 211 locks the first locking tongue 212. The rotation of the rotating connecting frame 200 drives the first locking tongue 212 to rotate. In the locked state, the first locking buckle 211 locks the first locking tongue 212, thus fixing the rotating connecting frame 200 and the base 100 relatively. After the first locking buckle 211 is unlocked, the first locking tongue 212 is allowed to disengage, and the rotating connecting frame 200 can rotate freely. The first locking buckle 211 is preferably a semi-automatic structure, meaning it can automatically lock. When the first locking tongue 212 moves to the first locking buckle 211, the first locking buckle 211 can automatically lock the first locking tongue 212 under its action. Unlocking requires manual intervention. The semi-automatic locking structure is a mature existing technology, and this application does not limit its specific structure.
[0031] Preferred, such as Figure 1 and Figure 3 As shown, the first locking mechanism 210 also includes a first unlocking mechanism. The first unlocking mechanism includes an unlocking operation end 213 and a connecting line. The unlocking operation end 213 is located on the flip frame 300, and the connecting line connects the unlocking operation end 213 and the first latch 211. Placing the unlocking operation end 213 on the flip frame 300 makes operation easier during use. Figure 1 and Figure 3As shown, the rotating connecting frame 200 is merely a bottom platform, and the flip frame 300 facilitates user operation. The connecting wires are not shown in the figure; however, it can be understood that the connecting wires connect the unlocking operation end 213 and the first latch 211, allowing the action of the unlocking operation end 213 to trigger the unlocking action of the first latch 211. This is existing technology, and this application does not limit its specific structure. The unlocking operation end 213 is preferably in the style of a bicycle brake lever, achieving component reuse and fully utilizing existing components in bicycle manufacturing enterprises.
[0032] Preferred, such as Figure 1 As shown, the base 100 is provided with at least two first latches 211, and a first latch 212 is located between the two first latches 211. At this time, the area between the two first latches 211 constitutes the range of motion of the first latch 212. Preferably, the range of motion of the first latch 212 can be set to a 90° rotation range.
[0033] Preferred, such as Figure 3 As shown, the second locking mechanism 310 is used to lock the flip frame 300 in the inverted state, preventing the flip frame 300 from flipping or shaking on its own. The specific structure of the second locking mechanism 310 can be the same as that of the first locking mechanism 210, including a second latch and a second lock.
[0034] Preferred, such as Figure 3 and Figure 4 As shown, a flipping limiting mechanism 320 is also provided between the flipping frame 300 and the rotating connecting frame 200. The flipping limiting mechanism 320 includes a limiting plate 321 and a limiting pin 324. The limiting plate 321 is rotatably mounted on the rotating connecting frame 200. The limiting plate 321 is provided with a limiting groove 322. The limiting pin 324 is fixed to the flipping frame 300 and slidably mounted in the limiting groove 322. When the flipping frame 300 flips, it drives the limiting pin 324 to slide in the limiting groove 322.
[0035] Specifically, such as Figure 4 As shown, when the flip frame 300 flips, it can drive the limiting pin 324 to slide within the limiting groove 322. The limiting groove 322 restricts the sliding range of the limiting pin 324, thus preventing the flip frame 300 from flipping excessively.
[0036] More preferably, such as Figure 4 As shown, the limiting plate 321 is also provided with at least one limiting groove 323. The limiting groove 323 intersects and communicates with the limiting slide 322. The flipping limiting mechanism 320 is configured such that when the limiting pin 324 moves to the position of the limiting groove 323, the limiting plate 321 rotates under its own weight, so that the limiting groove 323 covers the limiting pin 324.
[0037] The limiting groove 323 can realize the self-locking of the flipping limiting mechanism 320. That is, when the flipping frame 300 flips to the position, the limiting groove 323 covers the limiting pin 324, and the limiting pin 324 and the limiting groove 323 are locked together, and the flipping frame 300 cannot continue to flip. This can realize the automatic locking of the flipping frame 300 and prevent the flipping frame 300 from flipping back.
[0038] More preferably, at least two limiting grooves 323 are provided, thereby achieving a multi-level fixing effect on the flip frame 300.
[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
