Description

Technical Field

[0001] This utility model relates to the field of bicycle equipment, and in particular to a bicycle frame license plate structure. Background Technology

[0002] The description herein provides only background information in relation to this utility model and does not necessarily constitute prior art.

[0003] With the increasing popularity of automobiles, RVs, and other modes of transportation, the application of bicycle racks is becoming more widespread. The core need is to achieve convenient bicycle transportation and efficient space utilization. Therefore, foldable bicycles, due to their ability to reduce storage space occupation and improve vehicle compatibility through folding structures, have become the mainstream choice for vehicle-mounted applications. However, existing technologies have significant drawbacks in the bicycle folding and storage process: bicycle license plates are usually fixed to the frame. When the frame is folded, the license plate rotates with the frame, causing the length of the license plate to protrude beyond the outer contour of the folded bicycle. This not only disrupts the regularity of the storage space and causes instability when fixed in the vehicle, but also, because the license plate area is relatively fragile, it is easily deformed during transportation vibrations, affecting subsequent use.

[0004] To address the issue of securing license plates during folding, existing patented technologies (such as a clamping structure with a handle-linked double hook) use a handle to pull the handle, causing the two license plate hooks to slide open synchronously. Releasing the handle then uses a spring to reset the hooks, thus securing the license plate. However, this structure has significant drawbacks: when the license plate frame needs to be flipped to adjust its position, the pulling action can easily trigger the handle linkage mechanism, causing the hooks to accidentally loosen and the license plate to fall off. Furthermore, the synchronous single-handle operation relies on a single action to engage both hooks when clamping the license plate, resulting in a low fault tolerance rate and insufficient operational reliability.

[0005] To address the aforementioned issues, this utility model proposes a license plate holder flipping structure for a bicycle rack. By improving the license plate clamping method, the traditional single-handle linkage double-hook structure is optimized into a system where two hooks operate independently. Each hook is pulled individually to achieve engagement, requiring two independent actions to complete the clamping. This design avoids accidental operation due to accidental handlebar activation during license plate holder flipping, significantly improving the stability and reliability of license plate clamping. It effectively solves the technical problems of unstable license plate storage and easy detachment / deformation in existing technologies.

[0006] Therefore, how to solve this problem has become an urgent issue. Utility Model Content

[0007] To address the problems of irregular space occupation, unstable fixation, and easy deformation of license plates during the folding and storage of bicycles due to the rotation of the frame, and to solve the risk of accidental detachment caused by the single-handle linkage design of traditional license plate clamping structures, this utility model provides a license plate holder flipping structure for bicycle racks. By optimizing the flipping linkage mechanism and clamping method of the license plate holder, the angle of the license plate can be flexibly adjusted with the frame after the bicycle is folded, preventing it from protruding outside the storage space. At the same time, the independently operated double-hook clamping structure ensures that the license plate clamping process requires two independent locking actions, eliminating the risk of accidental loosening when flipping the license plate holder from the structural design, and improving the stability and reliability of the license plate during transportation.

[0008] A major advantage of this invention is that it provides a vehicle-mounted bicycle license plate holder structure with an anti-misoperation clamping design. It abandons the traditional synchronous clamping method of a single handlebar linked to two hooks, instead employing a dual-action operation logic where the two license plate hooks are independently pulled up and independently engaged. The license plate is only stably clamped when the user actively and sequentially engages the two hooks, preventing accidental loosening due to accidental contact with the handlebars when flipping the license plate holder, thus fundamentally eliminating the risk of misoperation.

[0009] A major advantage of this invention is that it provides a vehicle-mounted bicycle rack license plate structure, which optimizes space storage. Through a flip-up license plate bracket structure, the license plate can be adjusted to fit the folded outline of the bicycle rack after the bicycle is folded, preventing the license plate from protruding beyond the storage space in the length direction. This significantly improves the regularity of the folded bicycle's shape, facilitates vehicle mounting, and reduces the risk of bumps during transportation.

[0010] A major advantage of this invention is that it provides a vehicle-mounted bicycle rack license plate structure, which improves structural reliability. The independently snap-fit ​​double hook design disperses the license plate clamping force and reduces deformation caused by uneven force on a single hook. At the same time, it avoids the elastic attenuation or jamming that may be caused by long-term vibration in traditional spring linkage structures, thus extending the service life of the license plate bracket.

[0011] A major advantage of this invention is that it provides a vehicle-mounted bicycle license plate holder structure, wherein holding the license plate requires two distinct actions (pulling and engaging the two hooks respectively), and the operation process has clear step distinctions, allowing users to intuitively perceive the holding status, reducing the risk of misjudgment, and is especially suitable for quick loading and unloading and safety checks in vehicle scenarios.

[0012] A major advantage of this invention is that it provides a vehicle-mounted bicycle frame license plate structure. The design of the vehicle-mounted bicycle frame license plate structure is not dependent on a specific bicycle model. It can flexibly adapt to the license plate installation needs of various folding bicycle frames, and does not require major modifications to the existing bicycle main structure. It has broad application prospects and is easy to modify.

[0013] This utility model effectively solves the core problems of unstable license plate storage, easy detachment of clamps, and unreasonable space occupation in the prior art through innovative mechanical structure design. It has multiple advantages such as operational reliability, space utilization and structural durability, and significantly improves the user experience and transportation safety of bicycles mounted on vehicles.

[0036] It should be noted that the embodiments shown in the accompanying drawings are merely examples used to specifically and vividly explain and illustrate the concept of this utility model. They are not necessarily drawn to scale in terms of size and structure, nor do they constitute a limitation on the concept of this utility model.

[0037] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the various accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0038] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0039] Refer to the accompanying drawings in this application specification. Figures 1 to 3 As shown, a vehicle-mounted bicycle rack license plate structure according to a first preferred embodiment of this application will be described below. The vehicle-mounted bicycle rack license plate structure includes a license plate frame 10, a frame mounting mechanism 20, and a license plate fixing mechanism 30 disposed on the license plate frame 10. The license plate frame 10 has a mounting groove 101 for mounting the license plate, and the license plate fixing mechanism 30 is used to detachably fix the license plate to the mounting groove 101 of the license plate frame. The frame mounting mechanism 20 is disposed back-to-back on the other side of the mounting groove 101 of the license plate frame 10, for mounting the vehicle-mounted bicycle rack license plate structure to the bicycle frame.

[0040] The license plate fixing mechanism 30 includes at least two elastic clamping components 31, wherein the elastic clamping components 31 are disposed at intervals on the back of the license plate frame 10, and the elastic clamping components 31 extend from the back of the license plate frame 10 to the mounting groove 101 of the license plate frame 10, thereby fixing the license plate in the mounting groove 101.

[0041] It is worth mentioning that, in this preferred embodiment of the present application, the two elastic clamping components 31 of the license plate fixing mechanism 30 are spaced apart from each other and are independent of each other. That is, when operating the license plate fixing mechanism 30, the elastic clamping components 31 need to be operated separately and individually to avoid accidental operation that could cause the license plate to fall off, thus reducing the risk of operational errors.

[0042] In this preferred embodiment of the present application, the elastic clamping component 31 is disposed at the upper end or lower end of the license plate frame 10, or the elastic clamping component 31 is disposed at the left end or right end of the license plate frame 10, and the present application does not limit this.

[0043] The elastic clamping assembly 31 includes a housing 311, a locking block 312 disposed in the housing 311, and an elastic element 313, wherein the elastic element 313 and the locking block 312 have a pre-tightened elastic force. One end of the locking block 312 is disposed in the track of the housing 311, and the locking block 312 can move back and forth (up and down) along the track of the housing 311 within the housing 311. The other end of the locking block 312 extends into the mounting groove 101 of the license plate frame 10, corresponding to the license plate to be installed, and is used to restrict the movement of the license plate.

[0044] The elastic clamping assembly 31 and the license plate frame 10 form an adjustable mounting slot, in which the license plate can be detachably installed.

[0045] It is understood that the locking block 312 of the elastic clamping assembly 31 can move along the track direction within the housing 311 to realize the opening and closing of the elastic clamping assembly 31. When the locking block 312 is moved to open the mounting slot 101, the locking block 312 squeezes the elastic element 313, and the license plate can be installed into the mounting slot 101 or removed from the mounting slot. When the elastic element 313 squeezes the locking block 312 to move, and the locking block 312 returns to its initial position due to elasticity, the space within the mounting slot 101 is compressed, and the license plate is fixed in the mounting slot 101 by the elastic clamping assembly 31 and the license plate frame 10.

[0046] The license plate frame 10 further includes a license plate frame body 11 and a limiting protrusion 12 disposed on the license plate frame body 11, wherein the limiting protrusion 12 is disposed on the opposite side of the locking block 312 to limit the displacement of the license plate.

[0047] It is worth mentioning that, in this preferred embodiment of the present application, the limiting protrusion 12 is a fixing mechanism formed inside the mounting groove 101. Preferably, the limiting protrusion 12 of the license plate frame 10 is directly opposite the locking block 312.

[0048] The elastic clamping assembly 31 further includes an operating lever 314 and an operating handle 315 connected to the operating lever 314, wherein the operating handle 315 is connected to the operating lever 314, and the operating lever 314 is connected to the locking block 312, for driving the locking block 312 connected thereto to move within the housing 311 through the operating handle 315 and the operating lever 314.

[0049] like Figure 1 As shown, the frame mounting mechanism 20 of the vehicle-mounted bicycle frame and license plate structure includes a mounting bracket 21 and a limiting pin 22 disposed on the mounting bracket 21. The limiting pin 22 fixes the frame mounting mechanism 20 to the corresponding position on the vehicle frame.

[0050] The vehicle-mounted bicycle frame license plate structure further includes a rotating mechanism 40, wherein the rotating mechanism 40 is pivotally mounted on the license plate frame 10 and connected to the frame mounting mechanism 20, allowing the frame mounting mechanism 20 and the license plate frame 10 to rotate. The rotating mechanism 40 includes a first rotating arm 41 and a second rotating arm 42, wherein the first rotating arm 41 and the second rotating arm 42 are pivotally mounted on the back of the license plate frame 10, and the first rotating arm 41 and the second rotating arm 42 are arranged in parallel. When rotating, the first rotating arm 41 and the second rotating arm 42 rotate simultaneously to maintain the smoothness of the rotation of the frame mounting mechanism 20 and the license plate frame 10.

[0051] The license plate frame 10 further includes a first rotating hinge 13, a second rotating hinge 14, a third rotating hinge 15, and a fourth rotating hinge 16. The first rotating hinge 13 is disposed between one end of the first rotating arm 41 and the license plate frame 10, allowing relative rotation between the first rotating arm 41 and the license plate frame 10. The second rotating hinge 14 is disposed between the first rotating arm 41 and the vehicle frame mounting mechanism 20, allowing relative rotation between the first rotating arm 41 and the vehicle frame mounting mechanism 20. The third rotating hinge 15 is disposed between the second rotating arm 42 and the license plate frame 10, allowing rotation between the second rotating arm 42 and the license plate frame 10. The fourth rotating hinge 16 is disposed between the second rotating arm 42 and the vehicle frame mounting mechanism 20, allowing relative rotation between the second rotating arm 42 and the vehicle frame mounting mechanism 20.

[0052] Preferably, in this preferred embodiment of the present application, the first rotating hinge seat 13, the second rotating hinge seat 14, the third rotating hinge seat 15 and the fourth rotating hinge seat 16 are arranged sequentially on the back of the license plate frame 10.

[0053] It is worth mentioning that by setting four sets of hinge seats, the first rotating arm 41 and the second rotating arm 42 can be rotated and installed. When folding and storing, the first rotating arm 41 and the second rotating arm 42 rotate upward along the frame mounting mechanism 20, so that the license plate frame 10 is in a vertical state at the front end of the frame mounting mechanism 20, and at this time the length of the license plate frame 10 at the upper end of the frame mounting mechanism 20 is greater than the length at the lower end. When unfolding, the first rotating arm 41 and the second rotating arm 42 are rotated in the opposite direction, so that the license plate frame 10 is parallel to the frame mounting mechanism 20.

[0054] The vehicle-mounted bicycle frame license plate structure further includes a frame limiting mechanism 50, wherein the frame limiting mechanism 50 is disposed in a mounting groove of the frame mounting mechanism 20, and at least a portion of the frame limiting mechanism 50 protrudes outside the mounting groove. When the vehicle-mounted bicycle frame license plate structure is in the unfolded state, the frame limiting mechanism 50 can restrict the relative rotation of the license plate frame 10 and the frame mounting mechanism 20.

[0055] The frame limiting mechanism 50 includes a limiting card 51 and a limiting spring 52, wherein the limiting card 51 and the limiting spring 52 are in contact with each other, and the limiting spring 52 applies a pre-tightening force to the limiting card 51, so that the limiting card 51 automatically returns to its initial position.

[0056] It is worth mentioning that the license plate fixing mechanism 30 of this utility model adopts a split design, which includes two sets of independently operated elastic clamping components 31. Each set of components consists of a box 311, a locking block 312, an elastic element 313, an operating rod 314, and an operating handle 315.

[0057] In the existing technology, the structure of two locking blocks linked by a single operating handle has been improved to two sets of independent components. Each set of locking blocks 312 is moved independently by the operating handle 315 driving the operating rod 314. To release the license plate lock, both handles on both sides need to be pulled separately, to avoid the whole unit falling off due to accidental activation of a single handle when flipping the license plate frame.

[0058] The track of the locking block 312 is provided with a limiting boss (not shown) to ensure that it can only slide in a predetermined direction within the housing 311, and the preload of the elastic element 313 (such as a compression spring) acts independently on each locking block to ensure reset accuracy.

[0059] The operating handle 315 is recessed and embedded in the groove of the license plate frame 10. It needs to be pulled outward to trigger the displacement of the locking block 312, reducing the risk of accidental unlocking caused by vehicle vibration or external collision.

[0060] Card block 312 has anti-slip texture on the contact surface with the license plate (reference). Figure 3Combined with the rubber layer of the limiting protrusion 12, a bidirectional friction force is formed, which can maintain a partial clamping force even if there is a unilateral operation error.

[0061] The hinge point between the first rotating arm 41 and the second rotating arm 42 is fixed with fastening bolts to multiple angle settings, ensuring that the license plate frame 10 remains parallel to the vehicle frame mounting mechanism 20 when unfolded, thus avoiding obstruction of the license plate. A damping module (not shown) is added inside the hinge seat to provide progressive resistance during the flipping process, preventing inertial swaying of the license plate frame caused by rapid operation.

[0062] The limiting card 51 of the vehicle frame limiting mechanism 50 is linked to the rotation mechanism 40. When the license plate frame 10 is unfolded to a horizontal position, the limiting spring 52 pushes the limiting card 51 into the slot of the vehicle frame mounting mechanism 20, forming a mechanical lock. Unlocking requires pressing the limiting cards 51 on both sides simultaneously, further reducing the probability of accidental activation.

[0063] Through the above improvements, this structure, while maintaining the convenience of the original patent, completely solves the potential for misoperation during the flipping process and meets the mandatory requirements of traffic safety regulations for the stability of license plates.

[0064] In this preferred embodiment of the present application, the two elastic clamping components 31 of the license plate fixing mechanism 30 adopt an independently operable structure design, which differs from the traditional linkage clamping mechanism (e.g., a structure that links multiple clamping blocks through a single handle). Specifically, the two elastic clamping components 31 are spaced apart from each other and have no mechanical linkage relationship. That is, each elastic clamping component 31 is equipped with an independent operating handle 315 and a drive structure (such as an operating lever 314). The user needs to operate each elastic clamping component 31 individually (e.g., press or pull the corresponding operating handle 315 respectively) to install or remove the license plate.

[0065] It is worth noting that traditional vehicle license plate holders often employ a linkage clamping structure (e.g., multiple clamps are simultaneously opened or closed via a single operating handle). This type of structure is prone to malfunction due to vibration or external forces during vehicle operation (such as accidental contact with the operating handle when flipping the license plate holder), leading to the license plate falling off. This application, however, designs the elastic clamping component 31 with an independent operating mode, ensuring that the movement of each clamp 312 is controlled only by its corresponding operating handle 315, thus avoiding a chain reaction of malfunctions caused by a single operation. For example, when the license plate holder 10 needs to be flipped (by adjusting the angle via the rotating mechanism 40), even if one operating handle 315 is displaced due to contact, the other elastic clamping component 31 maintains a stable clamp on the license plate, significantly improving the reliability of the license plate fixation.

[0066] The elastic clamping assembly 31 further includes an independent operating lever 314 and an operating handle 315. The operating handle 315 is connected to the operating lever 314 in a one-to-one correspondence, and the operating lever 314 only drives the corresponding locking block 312 to move within the housing 311. In other words, the operating handle 315 of each elastic clamping assembly 31 is an independent component, requiring individual force to compress the elastic element 313 and disengage the locking block 312 from the license plate limiting position. When installing the license plate, the user needs to operate both operating handles 315 separately to open the corresponding locking blocks 312 synchronously (or asynchronously). After placing the license plate into the mounting slot 101, the user releases the operating handles 315, and the elastic element 313 drives the locking block 312 to reset and clamp the license plate. When disassembling, the user needs to operate both handles separately again to ensure that the clamping force on both sides of the license plate is released independently, avoiding the risk of the license plate falling off due to failure of a single operation.

[0067] It is worth mentioning that the limiting protrusion 12 on the inner side of the license plate frame body 11 and the locking block 312 of the elastic clamping component 31 form a bidirectional limiting structure: the limiting protrusion 12 is fixedly set on one side of the mounting groove 101 (such as the left or upper side), while the locking block 312 is pressed against the opposite side of the mounting groove 101 (such as the right or lower side) by elastic force. Since the two elastic clamping components 31 act independently, the upper and lower or left and right sides of the license plate can be clamped by the corresponding locking block 312 and the limiting protrusion 12 respectively. Even if one locking block is temporarily loosened due to misoperation, the other locking block can still maintain the limiting of the license plate by relying on elastic force, thereby effectively solving the safety hazard of loosening upon contact in the traditional linkage structure.

[0068] Understandably, since the license plate fixing mechanism 30 adopts an independent clamping design, when the license plate frame 10 is folded or unfolded by the rotating mechanism 40, there is no need to worry about the operation of the rotation causing interference to the license plate clamping state, which further improves the practicality and reliability of the overall structure.
