[0002] With economic development and improved living standards, people have higher and higher requirements for toys. As a result, there are a wide variety of toy cars on the market, each with its own design concept, striving to meet the playability and fun requirements of different players.

[0003] Owning a toy car has always been a dream for every child. Currently, the global annual production of toy cars reaches tens of millions, with domestically produced toy cars accounting for the majority of the market share. Toy cars for children to ride mainly consist of a frame, a front wheel, and a rear wheel.

[0004] Existing toy cars typically use a combination of front and rear wheel modules to support the rolling motion of the vehicle body, enabling forward and backward movement. Since toy cars have a certain size, they need to be rolled around when not in use. Because the wheels of the front and rear wheel modules are not fully exposed downwards, the chassis of the toy car will bump against the ground when rolled around like a suitcase. Therefore, it is more inconvenient to carry the toy car using a four-wheel rolling method with the front and rear wheel modules as the only option. Utility Model Content

[0005] The purpose of this invention is to provide a multi-point support stroller to address the shortcomings of existing technologies.

[0034] The present invention will now be described in detail with reference to the accompanying drawings.

[0035] like Figure 1-4 As shown, the multi-point support stroller includes a body 1, a steering wheel module 11 on the top of the body 1, a push structure 12 at the rear of the body 1, a front wheel module 13 and a rear wheel module 14 at the bottom of the body 1, and a pair of auxiliary support modules 2 on the front side of the bottom of the body 1. The auxiliary support module 2 includes auxiliary support wheels 21 and auxiliary mounting seats 22 for mounting the auxiliary support wheels 21. An auxiliary support shaft 24 is connected to the top of the auxiliary mounting seat 22. A fixing sleeve 3 for mounting the auxiliary support shaft 24 is longitudinally arranged at the bottom of the body 1. An elastic buffer structure connected to the auxiliary support shaft 24 is arranged inside the fixing sleeve 3.

[0036] When the stroller is in use, the auxiliary support module 2, together with the front wheel module 13 and the rear wheel module 14, can achieve multi-point rolling support, further improving the support stability of the stroller body 1. Depending on the road conditions, the auxiliary support wheel 21 can reduce vibration under the action of the elastic buffer structure, and has a buffering effect. In addition, since the push structure 12 is provided on the rear side of the stroller body 1, when the child is not in use, the auxiliary support wheel 21 of the auxiliary support module 2 can be lifted to roll with the ground, so as to achieve rolling carrying.

[0037] Furthermore, the auxiliary mounting base 22 is formed with a fixed mounting hole 23 for the auxiliary support shaft 24 to be inserted, and the bottom of the auxiliary support shaft 24 is formed with a bottom stop block 25 that cooperates with the stop of the fixed mounting hole 23, so that the auxiliary support shaft 24 can be fixedly connected with the fixed mounting hole 23 of the auxiliary mounting base 22, and the connection stability is better.

[0038] Furthermore, the elastic buffer structure includes a fixed seat 31 installed inside the fixed sleeve 3. The fixed seat 31 is formed with a central through hole 32 for the auxiliary support shaft 24 to pass through. A tension spring 33 is installed on the top of the fixed seat 31 to drive the auxiliary support shaft 24 to move elastically downward. Under the elastic drive of the tension spring 33, the auxiliary support shaft 24 installed inside the fixed sleeve 3 can slide elastically downward along the central through hole 32, so that the auxiliary support wheel 21 installed at the bottom of the auxiliary support shaft 24 can roll in contact with the ground to achieve auxiliary support.

[0039] Furthermore, the top of the auxiliary mounting base 22 is formed with a guide cylinder 34 that can be inserted into the fixed sleeve 3. The top of the auxiliary support shaft 24 is equipped with a top stop block 35, which is connected to the top of the tension spring 33. The guide cylinder 34 and the fixed sleeve 3 are coaxially slidably engaged to ensure that the position of the auxiliary support wheel 21 will not shift laterally.

[0040] It should be noted that the tension spring 33 has a certain elasticity and adopts a double spring structure. The tension spring 33 can provide elastic support for the entire toy car. After the guide movable cylinder 34 at the top of the auxiliary mounting seat 22 presses against the fixed seat 31 inside the fixed sleeve 3, it will not continue to retract. Even if the auxiliary support wheel 21 is in contact with the ground, there will be no situation where the elasticity retraction is too low, ensuring that the bottom of the car body 1 will not contact the ground, thereby realizing the function of rolling and carrying the toy car.

[0041] The bottom of the vehicle body 1 is provided with a foot support structure 4, which includes a foot fixing plate 41. At both ends of the foot fixing plate 41, foot support plates 42 are formed to support the bottom of the feet. The foot support plates 42 can support the child's feet and prevent the child's legs from hitting the ground and causing bumps, thus providing protection.

[0042] In addition, the foot pedal fixing plate 41 is provided with a connection structure for detachment and connection with the vehicle body 1. The connection structure includes a detachment and installation groove 43 formed in the bottom of the vehicle body 1, a horizontally arranged fitting groove 44 formed on the side wall of the detachment and installation groove 43, a first fitting seat 45 formed on the top of the foot pedal fixing plate 41, and a second fitting seat 46 formed horizontally on the top of the first fitting seat 45 to cooperate with the fitting groove 44. The fitting connection method allows the foot pedal fixing plate 41 to be detached and connected to the bottom of the vehicle body 1. When the bottom of the foot pedal fixing plate 41 is damaged or has silt accumulation, the second fitting seat 46 can be pulled out horizontally from the fitting groove 44 in the detachment and installation groove 43. Then the first fitting seat 45 can be pulled out vertically from the detachment and installation groove 43 to achieve disassembly. The whole process is convenient for disassembly and installation, and easy for replacement and maintenance.

[0043] Preferably, the bottom of the vehicle body 1 is formed with a longitudinally arranged side baffle 47, and the foot support plate 42 is located outside the side baffle 47. A locking groove 48 that mates with the side baffle 47 is formed between the foot fixing plate 41 and the foot support plate 42. After the foot fixing plate 41 is connected to the vehicle body 1, the locking groove 48 between the foot fixing plate 41 and the foot support plate 42 fits into the side baffle 47 at the bottom of the vehicle body 1. The side baffle 47 is embedded in the locking groove 48. At this time, the foot fixing plate 41 installed at the bottom of the vehicle body 1 will not move laterally, and its installation stability is further improved.

[0044] A seat structure 15 is installed on the top of the vehicle body 1. The seat structure 15 includes a seat groove 16 and a seat plate 17 installed on the top of the seat groove 16. A hinge block 18 is installed at one end of the seat plate 17. A hinge groove 19 is formed on the top of the vehicle body 1 to cooperate with the hinge block 18. The hinge block 18 and the hinge groove 19 are rotatably connected. The seat plate 17 can be flipped up through the rotational cooperation between the hinge block 18 and the hinge groove 19, which can cover the seat groove 16. When the seat plate 17 is opened, the seat groove 16 can be exposed. At this time, some small toys can be put into the seat groove 16 for temporary storage, increasing the space utilization rate.

[0045] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.
