[0001] This utility model relates to the field of children's vehicle technology, and in particular to a children's vehicle frame with a shock-absorbing structure. Background Technology

[0002] A baby stroller, also known as a children's stroller or baby carriage, is a means of transportation used to hold and transport infants and toddlers. It mainly consists of a frame, handlebars, and a seat. During daily use, uneven road surfaces cause vibrations in the stroller, which are transmitted to the rider's body through the frame and seat, causing vibrations. Excessive vibration can affect the comfort of infants and toddlers, easily causing them to cry. Therefore, the shock absorption performance of strollers is receiving increasing attention. Utility Model Content

[0003] This invention provides a stroller frame with a shock-absorbing structure, which can improve the comfort when using a child seat.

[0004] To solve the above-mentioned technical problems, this utility model provides a children's stroller frame with a shock-absorbing structure, characterized in that it includes:

[0005] The vehicle frame, wherein the vehicle frame is provided with at least a connecting rod

[0006] A wheel assembly, the wheel assembly including at least an axle and a wheel, the axle and the wheel being rotatably connected;

[0007] A shock-absorbing assembly includes a frame connector and a wheel connector. The frame connector has a frame connector hole, and a connecting rod is inserted into the frame connector hole. The wheel connector has a wheel connector hole, and an axle is inserted into the wheel connector hole. A shock-absorbing spring is provided between the frame connector and the wheel connector. The shock-absorbing spring is eccentrically positioned, and there is an angle between the central axis of the shock-absorbing spring and the central axis of the connecting rod.

[0008] As a preferred embodiment of the above technical solution, the angle between the central axis of the connecting rod and the horizontal plane is smaller than the angle between the central axis of the shock-absorbing spring and the horizontal plane.

[0009] As a preferred embodiment of the above technical solution, the angle between the central axis of the shock-absorbing spring and the horizontal plane is greater than 45°.

[0010] As a preferred embodiment of the above technical solution, the frame connector is provided with a spring receiving hole, the wheel connector is provided with a spring fixing part, the shock-absorbing spring is disposed in the spring receiving hole, and one end of the shock-absorbing spring abuts against the spring fixing part.

[0011] As a preferred embodiment of the above technical solution, the spring fixing part includes a receiving groove, and a fixing protrusion is provided in the receiving groove, with one end of the shock-absorbing spring inserted into the fixing protrusion.

[0015] This utility model provides a children's stroller frame with a shock-absorbing structure, including: a frame, a wheel assembly, and a shock-absorbing assembly. The shock-absorbing assembly achieves its shock-absorbing function through a shock-absorbing spring between the frame connector and the wheel connector, effectively reducing vibration transmission and improving the comfort of infants and toddlers. To ensure the stability of the frame itself, the connecting rod is generally inclined, making the overall frame structure smaller at the top and larger at the bottom, enhancing its anti-overturning ability. If the central axis of the shock-absorbing spring is parallel to the central axis of the connecting rod, the shock-absorbing spring is also inclined. When encountering bumpy roads and needing shock absorption, the shock-absorbing spring will often bend, failing to effectively perform its shock-absorbing function, resulting in a significant reduction in shock absorption effect. Therefore, it is necessary to ensure that the angle between the shock-absorbing spring and the connecting rod is reasonable to avoid bending the shock-absorbing spring, ensuring the shock absorption effect, while not affecting the overall frame structure (smaller at the top and larger at the bottom), ensuring the frame's anti-overturning ability.

[0016] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more obvious and understandable, specific embodiments of this utility model are given below.

[0022] To make the objectives, features, and advantages of this utility model more apparent and understandable, 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.

[0023] See Figures 1 to 4 This utility model embodiment provides a children's stroller frame with a shock-absorbing structure, characterized in that it includes:

[0024] The frame 1, wherein the frame 1 is provided with at least a connecting rod 101

[0025] Wheel assembly 2, the wheel assembly 2 including at least axle 201 and wheel 202, the axle 201 and wheel 202 being rotatably connected;

[0026] The shock absorption assembly 3 includes a frame connector 4 and a wheel connector 5. The frame connector 4 is provided with a frame connection hole 401, and the connecting rod 101 is inserted into the frame connector 401. The wheel connector 5 is provided with a wheel connection hole 501, and the axle 201 is inserted into the wheel connection hole 501. A shock absorption spring 6 is provided between the frame connector 4 and the wheel connector 5. The shock absorption spring 6 is eccentrically arranged, and there is an angle between the central axis of the shock absorption spring 6 and the central axis of the connecting rod 101.

[0027] This utility model embodiment provides a children's stroller frame with a shock-absorbing structure, including: a frame 1, a wheel assembly 2, and a shock-absorbing assembly 3. The shock-absorbing assembly 3 achieves shock absorption through a shock-absorbing spring 6 between the frame connector 4 and the wheel connector 5, effectively reducing vibration transmission and improving the comfort of infants and toddlers. To ensure the stability of the frame 1, the connecting rod 101 is generally inclined, making the frame 1 have a top-narrow and bottom-wide structure, enhancing its anti-overturning ability. If the central axis of the shock-absorbing spring 6 is parallel to the central axis of the connecting rod 101, then the shock-absorbing spring 6 is also inclined. When encountering bumpy roads and needing shock absorption, the shock-absorbing spring 6 will often bend and fail to effectively perform its shock absorption function, resulting in a significant reduction in the shock absorption effect. Therefore, it is necessary to ensure that the angle between the shock-absorbing spring 6 and the connecting rod 101 is reasonable to avoid bending the shock-absorbing spring 6, ensure the shock absorption effect, and at the same time, not affect the top-narrow and bottom-wide structure of the frame 1, ensuring the anti-overturning ability of the frame 1.

[0028] In a further embodiment of this invention, the angle between the central axis of the connecting rod 101 and the horizontal plane is smaller than the angle between the central axis of the shock-absorbing spring 6 and the horizontal plane.

[0029] In this embodiment, to ensure the anti-overturning capability of the frame 1, the angle between the central axis of the connecting rod 101 and the horizontal plane needs to be smaller, thereby relatively increasing the support area at the lower part of the frame 1 and further stabilizing the frame structure. At the same time, the angle between the central axis of the shock-absorbing spring 6 and the horizontal plane is relatively larger, so that the shock-absorbing spring 6 can be more effectively compressed and rebounded when subjected to vertical impact, absorbing vibration energy, reducing the impact on infants and young children, and improving the riding experience. Since the stroller will inevitably be subjected to horizontal impact force during the ride, the shock-absorbing spring 6 needs to have a certain tilt angle to take into account the shock absorption needs in both horizontal and vertical directions, ensuring that it can provide a stable shock absorption effect under various road conditions, and further protecting the safety and comfort of infants and young children.

[0030] In a further embodiment of this invention, the angle between the central axis of the shock-absorbing spring 6 and the horizontal plane is greater than 45°.

[0031] In this embodiment, the angle between the central axis of the shock-absorbing spring 6 and the horizontal plane is greater than 45°, which can take into account the shock absorption needs in both the horizontal and vertical directions, ensuring a stable shock absorption effect under various road conditions, and further protecting the safety and comfort of infants and young children.

[0032] In a further embodiment of this invention, the frame connector 4 is provided with a spring receiving hole 402, the wheel connector 5 is provided with a spring fixing part 502, the shock-absorbing spring 6 is disposed in the spring receiving hole 402, and one end of the shock-absorbing spring 6 abuts against the spring fixing part 502.

[0033] In this embodiment, the shock-absorbing spring 6 is disposed in the spring receiving hole 402, and one end of the shock-absorbing spring 6 abuts against the spring fixing part 502. During use, this prevents the shock-absorbing spring 6 from shifting, thereby ensuring the stability and reliability of the shock absorption effect. Furthermore, it prevents the shock-absorbing spring 6 from being exposed to the outside and easily damaged, improving overall safety performance. At the same time, this design facilitates quick replacement of the shock-absorbing spring 6 when needed, thus saving maintenance costs.

[0034] In a further embodiment of this invention, the spring fixing part 502 includes a receiving groove 503, and a fixing protrusion 504 is provided in the receiving groove 503. One end of the shock-absorbing spring 6 is inserted into the fixing protrusion 504.

[0035] In this embodiment, the receiving groove 503, in conjunction with the fixing protrusion 504, ensures that the shock-absorbing spring 6 remains stable during use, preventing it from loosening or falling off due to bumps, thus effectively preventing accidents and ensuring user safety. Furthermore, the design of the fixing protrusion 504 increases the contact area between the spring and the fixing part, helping to disperse stress and further improving the durability of the structure.

[0036] In a further embodiment of this invention, the fixing protrusion 504 is a cross-shaped fixing protrusion 504.

[0037] In this embodiment, the fixing protrusion 504 is a cross-shaped fixing protrusion 504, and its intersection point is exactly matched with the central axis of the shock-absorbing spring 6. This not only provides stronger support, but also effectively disperses the pressure acting on the shock-absorbing spring 6, reduces spring fatigue caused by excessive local force, and ensures the long-term stable operation of the stroller's shock absorption system.

[0038] In a further embodiment of this invention, the frame connector 4 is provided with a plug-in portion 403, the plug-in portion 403 is provided with a spring receiving hole 402, the wheel 202 connecting portion is provided with a connecting baffle 505, the number of connecting baffles 505 is two, and the plug-in portion 403 is disposed between the two connecting baffles 505.

[0039] In this embodiment, the plug-in portion 403 is disposed between the two connecting baffles 505. Through the cooperation between the plug-in portion 403 and the connecting baffles 505, the frame connector 4 and the wheel connector 5 can be stably connected, while allowing a certain degree of relative displacement, further enhancing the shock absorption effect. The connecting baffles 505 can also prevent foreign objects from entering the shock-absorbing spring 6, protecting the internal structure from damage.

[0040] In a further embodiment of this invention, the plug-in portion 403 is provided with a first connecting through hole 404, and the connecting baffle 505 is provided with a second connecting through hole 506, the positions of the first connecting through hole 404 and the second connecting through hole 506 correspond to each other.

[0041] In this embodiment, the plug-in part 403 is provided with a first connecting through hole 404, and the connecting baffle 505 is provided with a second connecting through hole 506. During assembly, screws or pins can be inserted into these through holes to achieve a stable connection between the frame connector 4 and the wheel 202 connection part. This structure facilitates assembly and maintenance.
