Description

Technical Field

[0001] This utility model belongs to the field of foldable vehicle technology, and in particular relates to a hanging ring assembly and a foldable vehicle. Background Technology

[0002] Foldable vehicles (such as scooters and folding bicycles) are portable short-distance transportation tools that typically require a lifting pole structure after folding for movement or storage (e.g., in a car trunk). To ensure a stable connection between the folded pole structure and the frame, existing technologies usually employ a combination of a hanging loop assembly and a hook: a hanging loop is installed on the pole structure, and a hook is installed on the frame. The folded state is secured by the engagement of the hanging loop and the hook, ensuring the vehicle remains stable when the user lifts the pole.

[0003] The existing hanging ring assembly has the following shortcomings:

[0004] 1) Some hanging ring components have overly simple structures, such as the hanging rings not being able to be stored and fixed, or the position and angle not being fixed. This may cause the hanging rings to be exposed when the foldable vehicle is unfolded, making them easy to snag on surrounding objects and affecting the safety and aesthetics of use. At the same time, when fixing them to the hook, manual and precise focusing is required, which is cumbersome and inefficient, resulting in a poor user experience.

[0005] 2) Some hanging ring assemblies use a spring-loaded ball bearing structure to limit the hanging ring position. However, this type of structure has a large number of parts, which increases the cost of parts and the difficulty of assembly. In addition, the ball bearing needs to be pressed hard into the mounting hole of the hanging ring seat, which requires extremely high assembly accuracy in terms of hole size and pressing depth. After long-term use, the ball bearing is prone to wear and loosening, resulting in locking failure.

[0006] Based on this, the present invention provides a novel hanging ring assembly and a foldable vehicle to overcome the above-mentioned defects. Utility Model Content

[0007] One objective of this utility model is to provide a hanging ring assembly, which consists of only four core components: a hanging ring base, a hanging ring, a limiting component, and a first energy storage component. The structure is simple and compact, which greatly reduces the assembly difficulty, improves production efficiency, and reduces the manufacturing and assembly costs of parts.

[0008] The present invention adopts the following technical solution:

[0009] A hanging ring assembly, comprising:

[0010] Hanging ring holder;

[0011] A hanging ring, one end of which is pivotally connected to the hanging ring base, and the hanging ring has a folded state and an unfolded state;

[0012] A limiting member is provided on the hanging ring seat to lock the hanging ring in the storage state;

[0013] The first energy storage component is connected to the hanging ring seat and the hanging ring respectively; when the hanging ring rotates from the unfolded state to the retracted state, the first energy storage component accumulates elastic potential energy.

[0014] Furthermore, the first energy storage element is a first torsion spring, one end of which is connected to the hanging ring seat, and the other end is connected to the hanging ring.

[0015] Furthermore, a limiting protrusion is formed on the side of the hanging ring away from the limiting member, and a limiting groove is formed on the hanging ring seat to cooperate with the limiting protrusion.

[0016] Furthermore, the limiting member includes:

[0017] A button component is movably installed in the limiting mounting cavity of the hanging ring seat. The button component is provided with a limiting part for engaging the hanging ring. The button component has a snap-on position and an unlocked position.

[0018] The second energy storage element is disposed between the button and the hanging ring seat;

[0019] When the button is in the snap-on position, the limiting part engages with the hanging ring; when the button switches from the snap-on position to the unlocked position, the second energy storage element accumulates elastic potential energy.

[0020] Furthermore, symmetrical limiting posts are provided on both sides of the top of the button component. The limiting posts cooperate with the inner wall of the limiting mounting cavity near the first energy storage component to restrict the displacement of the button component towards the first energy storage component.

[0021] Furthermore, the button is slidably mounted within the limiting mounting cavity of the hanging ring seat;

[0022] The second energy storage component is a first spring, one end of which abuts against the button component, and the other end abuts against the inner wall of the limiting mounting cavity of the hanging ring seat.

[0023] Furthermore, the bottom of the button component is rotatably connected to the hanging ring seat via a rotating shaft.

[0024] Furthermore, the second energy storage component is a second spring, one end of which abuts against the button component, and the other end abuts against the inner wall of the limiting mounting cavity of the hanging ring seat;

[0025] Alternatively, the second energy storage element is a second torsion spring, with one end of the second torsion spring connected to the hanging ring seat and the other end sleeved on the rotating shaft.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0027] In this invention, the hanging ring assembly is used by the user who applies external force to rotate the hanging ring around the pivot point, causing it to change from an unfolded state to a retracted state. During this process, one end of the first energy storage component is fixed to the hanging ring seat, and the other end is connected to the hanging ring. The rotation of the hanging ring forces the first energy storage component to deform, and elastic potential energy continues to accumulate. When the hanging ring reaches the retracted position, the limiting component engages with the hanging ring, locking it in the retracted state.

[0028] Operate the limiting component to release its mechanical constraint on the hanging ring. At this moment, the elastic potential energy of the first energy storage component is released instantaneously, driving the hanging ring to rotate around the pivot point. The elastic potential energy is converted into the kinetic energy of the hanging ring, and the corresponding hanging ring switches to the fully extended state.

[0029] In this invention, the hanging ring in the hanging ring assembly can rotate around the pivot joint. When an external force pushes it to rotate and retract into the hanging ring seat, the first energy storage component deforms due to its two ends being connected to the hanging ring seat and the hanging ring respectively, accumulating elastic potential energy. After reaching the retracted position, the limiting component immediately locks the hanging ring to ensure stable storage. When needed, simply release the constraint of the limiting component, and the first energy storage component quickly releases the stored potential energy, driving the hanging ring to automatically spring open to the preset unfolded state and be fixed in place by elastic force. The precise positioning angle facilitates quick connection with the hook component.

[0030] This hanging ring assembly consists of only four core components: a hanging ring base, a hanging ring, a limiting component, and a first energy storage component. Its simple and compact structure greatly reduces assembly difficulty, improves production efficiency, and simultaneously reduces parts manufacturing and assembly costs. Furthermore, in the unfolded state, the hanging ring extends outwards, providing stable support for hanging items, combining practicality and reliability, and is suitable for various scenarios.

[0031] The second objective of this utility model is to provide a foldable vehicle, which includes a frame body and a pole structure that can be folded relative to the frame body.

[0032] The aforementioned hanging ring assembly is mounted on the upright structure, and the hanging ring seat of the hanging ring assembly is fixedly connected to the upright structure;

[0033] The frame body is provided with a hook component. When the upright structure is folded relative to the frame body, the hanging ring in the hanging ring assembly is in the unfolded state, and the hanging ring is hooked and connected to the hook component.

[0034] Furthermore, the side of the hook that contacts the hanging ring is an inclined surface. Attached Figure Description

Detailed Implementation

[0047] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0048] The following is in conjunction with the appendix Figure 1 To be continued Figure 10 The present invention will be described in detail with reference to specific embodiments:

[0049] like Figures 1 to 10 As shown, this utility model provides a hanging ring assembly, which includes:

[0050] Hanging ring seat 1;

[0051] Hanging ring 2, one end of which is pivotally connected to the hanging ring seat 1 via a rotating shaft 10, the hanging ring 2 having a folded state and an unfolded state;

[0052] Limiting member 3, the limiting member 3 is disposed on the hanging ring seat 1, and is used to lock the hanging ring 2 in the storage state;

[0053] The first energy storage component 4 is connected to the hanging ring seat 1 and the hanging ring 2 respectively. When the hanging ring 2 rotates from the unfolded state to the retracted state, the first energy storage component 4 accumulates elastic potential energy. When the limiting component 3 releases the locking of the hanging ring 2 to the retracted state, the first energy storage component 4 converts the accumulated elastic potential energy into the kinetic energy of the hanging ring 2, causing the hanging ring 2 to switch to the unfolded state.

[0054] In this invention, the hanging ring assembly is used by the user who applies external force to rotate the hanging ring 2 around the pivot point, causing it to change from an unfolded state to a retracted state. During this process, one end of the first energy storage member 4 is fixed to the hanging ring seat 1, and the other end is connected to the hanging ring 2. The rotation of the hanging ring 2 forces the first energy storage member 4 to deform, and elastic potential energy continues to accumulate. When the hanging ring 2 reaches the retracted position, the limiting member 3 engages with the hanging ring 2, locking the hanging ring 2 in the retracted state.

[0055] Operate the limiting component 3 to release its mechanical constraint on the hanging ring 2. At this time, the elastic potential energy of the first energy storage component 4 is released instantaneously, driving the hanging ring 2 to rotate around the rotating shaft 10. The elastic potential energy is converted into the kinetic energy of the hanging ring 2, and the corresponding hanging ring 2 switches to the fully extended state.

[0056] In this invention, the hanging ring 2 in the hanging ring assembly can rotate around the pivot joint. When an external force pushes it to rotate and retract into the hanging ring seat 1, the first energy storage component 4 deforms due to its two ends being connected to the hanging ring seat 1 and the hanging ring 2 respectively, accumulating elastic potential energy. After reaching the retracted position, the limiting component 3 immediately locks the hanging ring 2 to ensure stable storage. When it is needed, simply release the constraint of the limiting component 3, and the first energy storage component 4 will quickly release the stored potential energy, driving the hanging ring 2 to automatically spring open to the preset unfolded state and be fixed in place by elastic force. The precise positioning angle facilitates quick connection with the hook component.

[0057] This hanging ring assembly consists of only four core components: a hanging ring base 1, a hanging ring 2, a limiting component 3, and a first energy storage component 4. Its simple and compact structure greatly reduces assembly difficulty, improves production efficiency, and reduces parts manufacturing and assembly costs. Furthermore, in the unfolded state, the hanging ring 2 extends outwards, providing stable support for hanging items, combining practicality and reliability, and is suitable for various scenarios.

[0058] Furthermore, in some specific embodiments, the first energy storage element 4 is a first torsion spring, with one end connected to the hanging ring seat 1 and the other end connected to the hanging ring 2. As a preferred embodiment, the first torsion spring is a double torsion spring structure. The two helical segments of this double torsion spring are coaxially sleeved on the outer circumference of the rotating shaft 10, with one end arm fixedly connected to the hanging ring seat 1 and the other end arm fixedly connected to the hanging ring 2. Through the parallel design of the double torsion springs, the elastic potential energy storage capacity can be increased several times compared to a single torsion spring; the coaxial constraint design between the helical segments and the rotating shaft 10 enhances system stability.

[0059] Furthermore, in some specific embodiments, such as Figure 3 As shown, a limiting protrusion 20 is formed on the side of the hanging ring 2 away from the limiting member 3. A limiting groove 12 is formed on the hanging ring seat 1 to cooperate with the limiting protrusion 20. Through the cooperation between the limiting protrusion 20 and the limiting groove 12, the final unfolding angle of the hanging ring 2 can be limited, so the preset unfolding angle of the hanging ring 2 can be designed according to actual needs. In embodiments one, two, and three, two limiting protrusions 20 are provided, and the two limiting protrusions 20 are spaced apart, resulting in good limiting stability.

[0060] It should be noted that the unfolded state of the hanging ring 2 mentioned in this utility model refers to the state when the hanging ring 2 is fully unfolded.

[0061] Furthermore, in some specific embodiments, the limiting member 3 includes:

[0062] A button component 30 is movably installed in the limiting mounting cavity 11 of the hanging ring seat 1. The button component 30 is provided with a limiting part 301 for engaging the hanging ring 2. The button component 30 has a snap-on position and an unlocked position.

[0063] The second energy storage element 31 is disposed between the button element 30 and the hanging ring seat 1;

[0064] When the button 30 is in the latched position, the limiting part 301 engages with the hanging ring 2, locking the hanging ring 2 in a stored state. When the button 30 is pushed from the latched position to the unlocked position, the second energy storage member 31 accumulates elastic potential energy and releases the lock on the hanging ring 2, allowing the hanging ring 2 to automatically spring open to the unfolded state under the action of the first energy storage member 4.

[0065] When it is necessary to store the hanging ring 2, first push the button 30 to the unlock position, then rotate the hanging ring 2 to the storage state. Next, release the button 30, and the second energy storage unit 31 releases the stored elastic potential energy and pushes the button 30 to switch to the buckle position, thereby achieving the snap-fit ​​limit of the hanging ring 2.

[0066] In this utility model, a second energy storage component 31 is provided at the limiting component 3. Through the dynamic process of "energy storage and energy release", the locking and unlocking control of the hanging ring 2 is realized. The operation is labor-saving and convenient, and it can automatically reset, making it suitable for high-frequency use scenarios.

[0067] Furthermore, symmetrical limiting posts 304 are also provided on both sides of the top of the button 30. Correspondingly, the limiting posts 304 cooperate with the inner wall of the limiting mounting cavity 11 near the first energy storage member 4 to restrict the displacement of the button 30 towards the first energy storage member 4, thereby achieving mechanical constraint on the button 30.

[0068] More specifically, such as Figure 3 , 4 As shown in Example 1:

[0069] The button component 30 is slidably installed in the limiting mounting cavity 11 of the hanging ring seat 1.

[0070] The second energy storage element 31 is a first spring. One end of the first spring abuts against the button 30, and the other end abuts against the inner wall of the limiting mounting cavity 11 of the hanging ring seat 1. In this embodiment, the other end of the hanging ring seat 1 is provided with a limiting mounting cavity 11, and a pushing part 302 can also be formed by extending upward on the upper surface of the button 30 to facilitate the pushing operation of the button 30.

[0071] In use, the pusher 302 is held to slide the button 30 towards the unlock position. At this time, the first spring deforms and stores energy. When the button 30 is released, the first spring releases the stored elastic potential energy and pushes the button 30 to switch to the latch position. It should be noted that the first spring can be located on the left or right side of the button 30. In this embodiment, it is located on the right side, that is, closer to the other end of the hanging ring seat 1. In this case, the first spring can be deformed due to compression when the button 30 is slid towards the unlock position. Similarly, when it is located on the left side, that is, closer to the hanging ring 2, the first spring can be deformed due to stretching when the button 30 is slid towards the unlock position.

[0072] like Figure 5 , 6 As shown in Embodiment 2, the bottom of the button component 30 is rotatably connected to the hanging ring seat 1 via a rotating shaft 303.

[0073] The second energy storage element 31 is a second spring. One end of the second spring abuts against the button 30, and the other end abuts against the inner wall of the limiting mounting cavity 11 of the hanging ring seat 1. In use, the button 30 is pressed in the unlocking direction. At this time, the second spring deforms and stores energy. When the button 30 is released, the second spring releases the stored elastic potential energy and pushes the button 30 to switch to the latching position.

[0074] In this embodiment, the limiting mounting cavity 11 is located at the other end of the hanging ring seat 1. Similarly, the second spring can be located on the left and right sides of the button part 30, and the design can be referenced from the first spring.

[0075] like Figure 7 , 8 As shown in Figure 9, in Embodiment 3, the bottom of the button component 30 is rotatably connected to the hanging ring seat 1 via a rotating shaft 303.

[0076] The second energy storage element 31 is a second torsion spring. One end of the second torsion spring is connected to the hanging ring seat 1, and the other end is connected to the button element 30. In this embodiment, the other end is sleeved on the rotating shaft. In use, the button element 30 is pressed in the unlocking direction. At this time, the second torsion spring deforms and stores energy. After the button element 30 is released, the second torsion spring releases the stored elastic potential energy and pushes the button element 30 to switch to the latching position.

[0077] The second torsion spring in this embodiment is also a double torsion spring structure. The two helical segments of the double torsion spring are coaxially sleeved on the outer periphery of the rotating shaft 303, with one end arm fixedly connected to the hanging ring seat 1 and the other end arm fixedly connected to the button component 30. Through the parallel design of the double torsion springs, the elastic potential energy reserve can be increased several times compared to the single torsion spring; the coaxial constraint design between the helical segments and the rotating shaft 303 enhances the system stability.

[0078] Based on the aforementioned hanging ring assembly, this utility model also provides a foldable vehicle, which includes a frame body 5 and a vertical pole structure 6 that can be folded relative to the frame body 5, such as... Figure 1 As shown. In this utility model, there is no limitation on how the upright structure 6 and the frame body 5 can be folded. For example, a folding device can be set at the connection between the two, and the folding device can adopt existing technology.

[0079] The aforementioned hanging ring assembly is mounted on the upright structure 6, and the hanging ring seat 1 of the hanging ring assembly is fixedly connected to the upright structure 6. In the above embodiments, the hanging ring seat 1 is fixedly mounted on the upright structure 6 by screws or the like, and the hanging ring seat 1 is arranged along the axial direction of the upright structure 6.

[0080] Correspondingly, the frame body 5 is provided with a hook 50. When the upright structure 6 is folded relative to the frame body 5, the hanging ring 2 is in the unfolded state. The hanging ring 2 is hooked and connected to the hook 50, so that the foldable vehicle can maintain its folded state. Figure 2 As shown.

[0081] Specifically, the side of the hook 50 that contacts the hanging ring 2 is inclined, which facilitates the insertion of the hanging ring 2.

[0082] In use, fold the upright structure 6 downwards. When the hanging ring 2 contacts the hook 50 on the frame body 5, continue folding downwards. When the force applied to the hanging ring 2 by the hook 50 is greater than the torsional force of the first torsion spring, the hanging ring 2 rotates a certain angle towards the folded-in state. Continue folding downwards and pressing the upright structure 6. As the angle of the hanging ring 2 changes, the position of the hanging ring 2 relative to the hook 50 moves away from the hook 50. When the hook 50 can be fully inserted into the hanging ring 2, the force applied to the hanging ring 2 by the hook 50 disappears, and the first torsion spring will quickly spring the hanging ring 2 open to the unfolded state. The hanging ring 2 is then locked into the hook 50, achieving automatic locking and fixing between the hanging ring 2 and the hook 50.

[0083] When it is necessary to release the fastener, continue to press down on the upright structure 6 and manually turn the hanging ring 2 away from the hook 50. The hanging ring 2 will rotate a certain angle towards the storage position, and the tail end of the hanging ring 2 will move away from the hook 50 relative to it. At this time, lifting the upright structure 6 will disengage the hanging ring 2 from the hook 50. Continuing to rotate the upright structure 6 upwards will reset it to its initial state.

[0084] This utility model discloses a foldable vehicle, which includes at least all the technical solutions of the above-mentioned hanging ring assembly and has at least all the advantages of the above-mentioned hanging ring assembly, which will not be repeated here.

[0085] Furthermore, the foldable vehicle incorporates a first torsion spring, enabling intelligent operation with "one-click folding and self-locking anti-detachment." Specifically, through the first torsion spring's energy storage and release mechanism, users only need to press down on the upright structure 6 to automatically and precisely engage the hanging ring 2 with the hook 50, significantly improving operational efficiency. Simultaneously, the continuous pre-tension force applied by the first torsion spring, combined with the inclined self-locking design, greatly enhances the vibration resistance in the folded state. Unlocking requires both "pressing down on the upright structure 6" and "pulling the hanging ring 2," minimizing the risk of accidental unfolding.

[0086] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
