Description

Technical Field

[0001] This utility model relates to the field of luggage technology, specifically to a children's luggage with convenient unfolding and foot pedal functions. Background Technology

[0002] With the increasing demands of modern travel, travelers who need to carry luggage while also caring for children face numerous inconveniences. Currently, various luggage designs incorporating child-friendly features have emerged.

[0003] For example, utility model patent application number "200920148808.9" discloses a suitcase with a child seat, which enables children to sit in it by fixing the child seat to the surface of the lid. However, this design has the safety hazard of the suitcase's center of gravity being unstable when a child is sitting in it, making it easy to tip over when parked; at the same time, the fixed child seat increases the size of the suitcase, making it inconvenient to carry and cumbersome to store.

[0004] In addition, there are children's suitcases on the market with four wheels on the bottom, allowing children to sit on top of the suitcase. However, in actual use, when a child's feet are dangling in the air, the lack of stable foot support not only causes discomfort for the child but also makes them prone to falling due to instability. When a child's feet are on the ground, adults pulling the suitcase will experience significant resistance due to their feet rubbing against the ground, affecting the efficiency of pushing the suitcase.

[0005] To address the aforementioned issues, some existing technologies have attempted to add foot pedals to children's suitcases, but most of these designs are manual pull-out designs, requiring users to actively unfold or retract the foot pedals. This makes them inconvenient to use and may cause storage difficulties if the pedals are not fully retracted.

[0006] Therefore, there is an urgent need for a children's suitcase with convenient unfolding and retraction of the foot pedal, which not only improves the safety and comfort of children riding in it, but also enables the foot pedal to be quickly popped out and retracted through one-button operation, thereby optimizing the user experience. Utility Model Content

[0007] To address the problems of inconvenient operation, insufficient safety, and inadequate comfort of existing foot pedal devices in children's suitcases, this invention provides a children's suitcase where the foot pedal can be quickly extended and retracted with a single button operation, thereby improving the safety and comfort of children and optimizing the user experience.

[0008] To achieve the above object, a children's suitcase designed by the utility model comprises a box body and an aluminum alloy frame. The box body is formed by splitting a left shell and a right shell into two equal parts. A pedal and a pedal telescopic mechanism are provided at the bottom of each of the left shell and the right shell. The pedal telescopic mechanism includes: a receiving cavity, which is a cavity with a single-sided opening formed by cavity plates, providing an installation space and protection for the internal components of the pedal telescopic mechanism; a guiding seat, which is arranged in the receiving cavity, with a groove on its upper surface and a limiting unlocking seat protruding in the groove, jointly forming a guiding groove; and a limiting hole is also provided on the side surface of the guiding seat.

[0009] The guiding groove includes: a low-position locking section, in which a locking limiting platform is provided; a high-position unlocking section, in which an unlocking limiting platform is provided, and the unlocking limiting platform and the locking limiting platform are parallel to each other in the plane where the guiding groove is located to assist in realizing the switching between the locked and unlocked states of the pedal; a first upward stopping section, in which a first stopping platform is provided; and a second upward stopping section, in which a second stopping platform is provided; the low-position locking section, the high-position unlocking section, the first upward stopping section and the second upward stopping section jointly constitute several key positioning points of a preset movement trajectory with mutual linkage.

[0010] A first locking member, on the upper surface of which a through hole is provided, and two limiting columns capable of sliding in the limiting holes are provided on the side surface, and a compression spring is sleeved on the limiting columns, and the compression spring abuts between the first locking member and the guiding seat, providing an elastic restoring force for the first locking member to move away from the guiding seat.

[0011] A connecting rod, which is in a "C" shape structure, one end of which is a sliding end, and the sliding end is accommodated in the guiding groove and can slide along the preset movement trajectory of the guiding groove; the other end of the connecting rod is pivotally connected to the through hole of the first locking member, transmitting the pressing action of the pedal and changing the position of the first locking member according to the trajectory of the guiding groove.

[0012] A second locking member, with a locking portion provided at its end, and the second locking member is pivotally arranged in the receiving cavity and can swing between a locking position and a releasing position; when the first locking member moves towards the pedal and abuts against the second locking member, the locking portion of the second locking member is in the locking position; when the first locking member moves towards the guiding seat and there is a gap with the second locking member, the locking portion of the second locking member is in the releasing position, and the locking and unlocking of the pedal are realized through the cooperation with the first locking member.

[0013] The pedal is pivotally mounted in the receiving cavity via a torsion spring. It tends to be driven by the torsion spring to rotate and extend out of the receiving cavity. Under the action of an external driving force, the pedal can rotate to touch and push the first locking member to move towards the guide seat. At the same time, the pedal is provided with a locking groove, which cooperates with the locking part of the second locking member. When the locking part is in the locked position, it engages with the locking groove to restrict the movement of the pedal.

[0014] A further solution is that the preset motion trajectory is specifically outlined and connected by multiple integrally formed guide slopes, including a second unfolding slope. The second unfolding slope is disposed between the locking limiting platform and the first stopping platform to guide the sliding end of the connecting rod to the first stopping platform, so that the pedal can smoothly transition from the locked state to the unfolded state.

[0015] A first recovery ramp extends from the first stop platform and is positioned on the path from the unlocking limit platform to the second stop platform;

[0016] A third recovery ramp is provided between the second stop platform and the locking limit platform to guide the sliding end of the connecting rod back to the locking limit platform, ensuring that the movement path of the pedal is clear and error-free at different operating stages; the unlocking limit platform is provided on this unlocking limit seat, and the unlocking limit seat also includes:

[0017] A first deployment ramp, starting above the locking stop and extending towards the second deployment ramp, guides the sliding end of the connecting rod towards the second deployment ramp, ensuring the connecting rod correctly enters the deployment path upon initial pressing. An unlocking guide ramp guides the connecting rod to the unlocking stop after its sliding end leaves the first stop, precisely guiding the pedal from the deployed to the unlocked state. These specific guide ramps optimize the smoothness and accuracy of the connecting rod's movement within the guide groove, reducing the risk of mechanism jamming.

[0018] A further improvement involves forming a second recovery slope on the limiting unlocking seat. This second recovery slope extends from the unlocking limiting platform and faces the third recovery slope, working in conjunction with the second stop platform to ensure that the sliding end of the connecting rod can move smoothly towards the third recovery slope. This structure further prevents the sliding end of the connecting rod from falling back to the high unlocking section, ensuring the reliability and smoothness of its movement back to the locked position after unlocking.

[0019] Furthermore, a tension spring is provided between the second locking member and the inner wall of the receiving cavity. The tension spring causes the second locking member to tend to leave the locking groove, i.e., to tend towards the release position. In this way, when the first locking member moves towards the guide seat and no longer presses on the second locking member, the second locking member can more actively and quickly disengage from the locking groove of the pedal, which is beneficial for the rapid unlocking and retraction of the pedal.

[0020] The top of the box has a recessed area. This recessed area allows children to sit comfortably.

[0021] The top of the enclosure is equipped with a fastener that engages the left and right shells. This fastener allows the enclosure to be effectively closed and locked.

[0022] The top of the suitcase also features two symmetrical handles. These handles make it easier for children to grip the suitcase while riding, enhancing their user experience.

[0023] A handle is provided on the left side of the suitcase. This handle makes it easy for adults to carry the suitcase with one hand when it is inconvenient to drag it or when children are not riding it, thus enhancing the suitcase's portability.

[0024] A shaft is located at the bottom of the housing for hinged connection between the left and right shells. This hinge structure ensures the flexible opening and closing of the two shell halves while maintaining the integrity and durability of the housing structure.

[0025] The beneficial effects of this utility model are as follows: This children's suitcase adopts a press-triggered telescopic foot pedal mechanism. Through the cooperation of the guide groove, connecting rod, and spring assembly, the pedal can be popped out and retracted with just a press. Operation is convenient and requires no manual adjustment, optimizing the user experience. The pop-out pedal provides stable foot support for children riding in the suitcase, avoiding the risk of imbalance caused by feet dangling in the air or the pushing resistance caused by feet dragging on the ground in traditional designs. Combined with the recessed part on the top of the suitcase and the handle design, it further enhances the stability and comfort of children riding in the suitcase. At the same time, the pedal can be well accommodated in the storage cavity when retracted, maintaining the overall aesthetics and portability of the suitcase, without affecting its use as a regular suitcase for dragging and storage. The application of the aluminum alloy frame effectively improves the overall load-bearing capacity and impact resistance of the suitcase, providing a more solid guarantee for children's safety.

Detailed Implementation

[0033] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0034] Example 1.

[0035] like Figures 1 to 6 As shown in the figure, this embodiment describes a children's suitcase, including a suitcase body 1 and an aluminum alloy frame 11. The suitcase body 1 is composed of a left shell 111 and a right shell 112, which are split in half to facilitate the storage and retrieval of items. The bottom of both the left shell 111 and the right shell 112 is provided with a foot pedal 8 and a foot pedal telescopic mechanism, so that both sides of the suitcase can provide foot pedal functionality.

[0036] Specifically, the pedal telescopic mechanism includes the following components:

[0037] Receiving cavity 2, such as Figure 2 and Figure 4As shown, the receiving cavity 2 is a rectangular cavity with a single-sided opening, formed by cavity plates. It provides an installation space for other internal components of the pedal telescopic mechanism and also provides some support and protection. The single-sided opening is used for the extension and retraction of the pedal 8.

[0038] Guide seat 3, such as Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the guide seat 3 is disposed inside the receiving cavity 2. Relative to the single-sided opening, the guide seat 3 is positioned at the apex of the receiving cavity 2, and at least two of its sides are fixedly connected to the inner wall of the receiving cavity 2. A groove is provided on the upper surface of the guide seat 3, and a protruding limiting and unlocking seat 34 is integrally formed within the groove. The groove and the limiting and unlocking seat 34 together form a guide groove with a specific complex trajectory. Simultaneously, two limiting holes 35 are opened on the side of the guide seat 3 facing the single-sided opening, as shown... Figure 6 As shown.

[0039] The guide groove mentioned above is mainly referred to Figure 3 and Figure 6 It is the key structure for realizing the self-locking function of the pedal extension, and its internal preset complex trajectory consists of the following sections and limiters:

[0040] A low-position locking section 31 is provided with a locking limit platform 311; a high-position unlocking section 32 is provided with an unlocking limit platform 321, and the unlocking limit platform 321 and the locking limit platform 311 are parallel to each other on the plane where the guide groove is located. This means that the high-position unlocking section 32 and the low-position locking section 31 are at different distances from the side where the limiting hole 35 is located. This distance difference is the key to realizing the locking and unlocking functions. More specifically, it is through two different distances that other components are controlled, thereby switching between the locking and unlocking states.

[0041] The system comprises a first upward stopping section 33A, within which a first stopping platform 33A1 is provided; and a second upward stopping section 33B, within which a second stopping platform 33B1 is provided. The low-position locking section 31, the high-position unlocking section 32, the first upward stopping section 33A, and the second upward stopping section 33B are interconnected by specific guide slopes, and the endpoints or specific platforms of these sections constitute several key positioning points on the trajectory.

[0042] First locking element 4, such as Figure 2 , Figure 4 and Figure 5As shown, a through hole 41 is provided in the middle of the upper surface of the first locking member 4. Two limiting columns 42 extend integrally from its side surface. These two limiting columns 42 respectively correspond to and are slidably inserted into two limiting holes 35 on the side surface of the guide seat 3, so as to ensure that the first locking member 4 can only move stably along the axial direction of the limiting column 42. A compression spring 5 is sleeved on each limiting column 42. One end of the compression spring 5 abuts against the first locking member 4, and the other end abuts against the guide seat 3. In this way, the compression spring 5 always applies an elastic restoring force to the first locking member 4 to make it away from the guide seat 3.

[0043] The connecting rod 6, as Figure 2 , Figure 4 and Figure 5 shown, the connecting rod 6 is preferably made of metal and is generally in a "C" shape as a whole. One end of it is a sliding end, which is accommodated in the guide groove on the upper surface of the guide seat 3 and can move back and forth between the locking limiting platform 311 and the unlocking limiting platform 321 along the aforementioned complex trajectory. The other end of the connecting rod 6 is pivotally connected to the through hole 41 on the upper surface of the first locking member 4. This connection method enables the connecting rod 6 to be converted into a constraint on the position of the entire first locking member 4 through the constraint of its sliding end, so that the first locking member 4 has two determinable positions of approaching and departing from the guide seat 3.

[0044] The second locking member 7, as Figure 2 , Figure 4 and Figure 5 shown, the second locking member 7 is a pivotable locking claw. One end of it, such as the lower end shown in Figure 4 , is provided with a locking portion 71 bent inward. The second locking member 7 is pivotally installed in the accommodating cavity 2 through its upper pivot shaft, so that it can swing freely between the locking position and the release position. When the first locking member 4 moves away from the guide seat 3 under the elastic force of the compression spring 5, the first locking member 4 presses against the second locking member 7 and will force the locking portion 71 of the second locking member 7 to swing inward, tending to be stuck in the locking position of the locking groove 81 of the pedal 8. On the contrary, when the first locking member 4 moves towards the guide seat 3 and forms a sufficient gap with the second locking member 7 and no longer applies pressure to it, the locking portion 71 of the second locking member 7 can get out of the locking groove 81 of the pedal 8 and be in the release position.

[0045] The pedal 8, as Figure 1 , Figure 2 and Figure 4As shown, the pedal 8 is for a child to step on. It is pivotally mounted in the receiving cavity 2 via a torsion spring 9. The elasticity of the torsion spring 9 gives the pedal 8 a constant tendency to be driven to rotate and extend out of the receiving cavity 2. When the pedal 8 is in the retracted state, the user can overcome the elasticity of the torsion spring 9 by pressing the pedal 8 inward, causing the pedal 8 to rotate into the receiving cavity 2. The inner end of the pedal 8 will touch the first locking member 4 and push the first locking member 4 towards the guide seat 3. At the same time, a locking groove 81 is provided at the position of the locking part 71 of the second locking member 7 on the pedal 8. The shape and position of the locking groove 81 cooperate with the locking part 71 of the second locking member 7. When the locking part 71 is in the locked position, it will be embedded in this locking groove 81, thereby firmly restricting the movement of the pedal 8.

[0046] Reference Figure 3 and Figure 5 As shown, in this embodiment, to further optimize the guiding function of the guide groove and make the movement of the sliding end of the connecting rod 6 smoother and more precise, the preset motion trajectory is specifically outlined and connected by the following integrated guide slopes, including: a second unfolding slope 313, which is set between the outlet of the locking limit platform 311 and the inlet of the first stop platform 33A1, forming an upward slope, used to guide the sliding end of the connecting rod 6 to smoothly slide upward from the low locking section 31 to the first stop platform 33A1 of the first upward stop section 33A when the pedal 8 is pressed for the first time, so that the pedal 8 can smoothly transition from the locked state to the unfolded state. A first retraction slope 314, which is led out from the outlet of the first stop platform 33A1 and is set on the path from the unlocking limit platform 321 to the second stop platform 33B1. A third recovery ramp 315, connected between the outlet of the second stop platform 33B1 and the inlet of the locking limit platform 311, forms a descending slope. This ramp guides the sliding end of the connecting rod 6 to smoothly return from the second upward stop section 33B and fall back into the locking limit platform 311 of the low-position locking section 31 after the pedal 8 is pressed and unlocked for the second time, thus completing the retraction and locking of the pedal 8. The unlocking limit platform 321 is mounted on the limit unlocking seat 34, and the limit unlocking seat 34 further includes:

[0047] A first deployment ramp 312 starts "above" the locking limit platform 311, i.e., the position where the sliding end of the connecting rod passes due to the pedal pressing, and extends towards the second deployment ramp 313. Its function is to guide the sliding end of the connecting rod 6 to the starting end of the second deployment ramp 313 after it leaves the locking limit platform 311 due to external driving force, ensuring that the sliding end of the connecting rod 6 can correctly enter the deployment path. And an unlocking guide ramp 341 is located on the limit unlocking seat 34, which is specifically used to accurately guide the sliding end of the connecting rod 6 to the high unlocking section 32 where the unlocking limit platform 321 is located after it leaves the first stop platform 33A1 due to external driving force.

[0048] To ensure that the sliding end of link 6 does not fall back or get stuck after passing the unlocking limit platform 321, and can smoothly enter the final recovery path, preferably, a second recovery slope 342 is also provided on the limit unlocking seat 34. The second recovery slope 342 extends from the outlet of the unlocking limit platform 321 and extends towards the inlet of the third recovery slope 315. It works together with the subsequent second stop platform 33B1 to ensure that after leaving the unlocking limit platform 321, the sliding end of link 6 can continue to slide along the preset path towards the second stop platform 33B1, and finally return to the locking limit platform 311 via the third recovery slope 315.

[0049] like Figure 2 and Figure 4 As shown, to make the unlocking action of the second locking member 7 more sensitive and reliable, in this embodiment, a tension spring 10 is also connected between the other side of the non-locking part of the second locking member 7 and the inner wall of the receiving cavity 2. The tension spring 10 is in a pre-stretched state, and its elastic force always acts on the second locking member 7, giving it a tendency to actively disengage from the locking groove 81 and move towards the release position. In this way, once the guide seat 3 of the first locking member 4 moves and no longer applies pressure to the second locking member 7, the tension spring 10 can quickly pull the second locking member 7 away from the locking groove 81, thereby achieving rapid unlocking.

[0050] In some embodiments, such as Figure 1 As shown, a recess 12 is provided on the top of the housing 1. This recess is ergonomically designed for children to ride in, providing a relatively comfortable riding area for them.

[0051] In some embodiments, a fastener is also provided on the top of the housing 1 for fastening and securing the left shell 111 and the right shell 112. The fastener enables the housing to be effectively closed and locked.

[0052] In some embodiments, two handles 13 are symmetrically arranged on the top of the suitcase 1. These two handles make it easier for children to grip when riding the suitcase, increasing stability and safety.

[0053] In some embodiments, a handle 14 is provided on the side of the left shell 111 of the case 1 or at another suitable location. This handle allows an adult to carry the entire suitcase with one hand when it is inconvenient to drag it or when a child is not riding it.

[0054] In some embodiments, a through shaft is provided at the bottom of the housing 1 for pivotally connecting the left shell 111 and the right shell 112, so that the housing can open and close around the shaft.

[0055] In this embodiment, when the pedal 8 is in the initial retracted and locked state, the sliding end of the connecting rod 6 is located at the locking limit platform 311 of the low-position locking section 31 of the guide groove inside the guide seat 3. In this state, the first locking member 4 is positioned away from the guide seat 3 by the elastic force of the compression spring 5 and presses against the second locking member 7. Its locking part 71 is engaged in the locking groove 81 of the pedal 8, thereby locking the pedal 8 in the retracted position.

[0056] When the user presses the pedal 8 inward for the first time, the pedal 8 overcomes the elastic force of the torsion spring 9 and pushes the first locking member 4 towards the guide seat 3. The movement of the first locking member 4 drives the connecting rod 6, whose sliding end slides upward within the guide groove along the guidance of the first unfolding slope 312 and the second unfolding slope 313, and is blocked by the first stop platform 33A1 of the first upward stop section 33A. During this pressing process, as the first locking member 4 moves closer to the guide seat 3, its pressure on the second locking member 7 is released, and the tension spring 10 then pulls the second locking member 7, causing its locking part 71 to disengage from the locking groove 81 of the pedal 8, thus unlocking the pedal 8. When the user releases the pressure on the pedal 8, under the partial rebound force of the compression spring 5, the first locking member 4 will move slightly away from the guide seat 3, causing the sliding end of the connecting rod 6 to slide down from the first stop platform 33A1, and along the guidance of the unlocking guide slope 341, finally stopping stably on the unlocking limit platform 321 within the high unlocking section 32. Because the unlocking limit platform 321 is at a relatively "high" position compared to the initial locking limit platform 311, meaning the first locking member 4 is closer to the guide seat 3, the travel of the first locking member 4 is insufficient to press the second locking member 7 to the locking position. Therefore, the second locking member 7 remains in the released state under the action of the tension spring 10, while the elastic force of the torsion spring 9 drives the unlocked pedal 8 to automatically rotate outward and extend, and remain in the extended state.

[0057] When the user needs to retract pedal 8 into the receiving cavity 2, they press the unlocked pedal 8 inward again. Pedal 8 pushes the first locking member 4 towards the guide seat 3 again, and the sliding end of the connecting rod 6 starts from the unlocking limit platform 321 of its high unlocking section 32, and continues its preset trajectory under the guidance of the guide groove: passing through the first recovery slope 314, reaching the second stop platform 33B1 of the second upward stop section 33B. After the user releases pedal 8, the sliding end of the connecting rod 6 slides downward under the guidance of the second recovery slope 342 and the third recovery slope 315, returns and falls back into the locking limit platform 311 of the low locking section 31. In this embodiment, the elastic force generated by the compression spring 5 is greater than the pulling force of the tension spring 10 to open the second locking member 7, which can push the first locking member 4 away from the guide seat 3 to its maximum stroke, and apply sufficient pressure to the second locking member 7 again. The locking part 71 of the second locking member 7 re-engages into the locking groove 81 of pedal 8, thereby completing the retraction and locking of pedal 8.
