Technical Field
[0001] This utility model relates to the field of baby stroller technology, specifically to a folding clutch transmission structure system for baby strollers. Background Technology
[0002] A stroller is a tool designed to facilitate outdoor activities for infants. It has become an indispensable means of transportation in the process of children's growth. Not only is it easy to move, which can help parents reduce physical labor, but it can also carry toys and other supplies, making it convenient for infants to play. As people's living standards improve, people have higher and higher requirements for the quality of strollers.
[0003] However, most existing stroller frames are manually folded, which makes the stroller inconvenient to use and the folding and closing operation complicated.
[0004] Therefore, it is necessary to provide a folding clutch transmission system for strollers with a simple structure and a quick-folding frame to overcome the shortcomings of the prior art. Utility Model Content
[0005] In order to overcome the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a folding clutch transmission structure system for strollers.
[0006] This utility model is achieved through the following technical solution: a folding clutch transmission structure system for a stroller, including a frame with a front wheel seat, a rear wheel seat, support legs, and a U-shaped handle. A front wheel is provided at the bottom of the front wheel seat, and a rear wheel is provided at the bottom of the rear wheel seat. The front wheel seat is connected to the rear wheel seat through a reducer mounting base. One end of the support leg is hinged to the U-shaped handle, and the other end is rotatably connected to the reducer mounting base. It also includes a clutch transmission structure for controlling the folding of the support leg and the front wheel seat. The clutch transmission structure includes a transmission shaft connected between the support legs on both sides and a folding motor for driving the transmission shaft. Reducers are provided at both ends of the transmission shaft. The reducers are located between the front wheel seat and the support leg, and the output end of the reducer is engaged with the support leg.
[0007] Preferably, the transmission shaft of this utility model is provided with a bushing and a push handle that can be slidably connected to or separated from the output end of the folding motor. When the push handle is connected to the folding motor, it is engaged with the bushing; when the push handle is separated from the folding motor, it is separated from the bushing.
[0008] Preferably, the cross-sections of the drive shaft and bushing of this invention are both polygonal.
[0009] Preferably, the outer surface of the push handle of this invention has anti-slip stripes.
[0010] Preferably, one end of the support leg of this utility model is rotatably connected to the reducer mounting base via a rotating seat. The reducer is located between the rotating seat and the reducer mounting base, and its output end is engaged with the rotating seat. The transmission shaft passes through the rotating seat and is connected to the reducer for transmission.
[0011] Preferably, the reducer mounting base of this utility model is connected to the rear wheel seat through an elastic element.
[0012] Preferably, the speed reducer mounting base of this utility model is rotatably connected to the U-shaped handle via a connecting rod.
[0013] Compared with the prior art, this utility model has the following advantages and beneficial effects: 1. This utility model uses a folding motor to drive the transmission shaft to fold the two sides of the frame, so that the support legs and the front wheel seat can be folded and folded together. No manual folding is required, and the frame can be quickly folded together. It is simple to operate and highly efficient.
[0014] 2. This utility model also features a push handle that can slide on the drive shaft. The push handle can engage and disengage with the folding motor and drive the drive shaft, thus enabling the frame to be manually folded even when there is no power. Attached Figure Description

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0019] Reference Figures 1 to 5 As shown, a folding clutch transmission structure system for a stroller includes a frame with a front wheel seat 1, a rear wheel seat 2, support legs 3, and a U-shaped handle 4. A front wheel 10 is located at the bottom of the front wheel seat 1, with the front wheel 10 distributed on both sides of the bottom of the front wheel seat 1. A rear wheel 20 is located at the bottom of the rear wheel seat 2, with the rear wheel 20 distributed on both sides of the bottom of the rear wheel seat 2. The front wheel seat 1 is connected to the rear wheel seat 2 via a reducer mounting base 5. One end of the support leg 3 is hinged to the U-shaped handle 4, and the other end is rotatably connected to the reducer mounting base 5. The system also includes a clutch transmission structure for controlling the folding of the support legs 3 and the front wheel seat 1. The clutch transmission structure includes a drive shaft 6 connected between the support legs 3 on both sides and a folding motor 7 for driving the drive shaft 6. The output of the folding motor drives the drive shaft to rotate, thereby achieving synchronous rotation of the frame.
[0020] Both ends of the drive shaft 6 are equipped with reducers 8, which are located between the front wheel seat 1 and the support leg 3. The output end of the reducer 8 is engaged with the support leg 3. The reducers on both sides can increase the load-bearing capacity of the folding motor, so that the sides of the vehicle can be folded more easily.
[0021] The drive shaft 6 is equipped with a bushing 60 and a push handle 61 that can be slidably connected to or separated from the output end of the folding motor 7. When the push handle 61 is connected to the folding motor 7, it is engaged with the bushing; when the push handle is separated from the folding motor 7, it is also separated from the bushing 60. The push handle allows the stroller frame to be manually folded even when there is no power. Both the drive shaft 6 and the bushing 60 have polygonal cross-sections.
[0022] To further increase the friction of the push handle surface so that it does not slip when manually turning, and to better facilitate manual folding of the frame, anti-slip stripes are provided on the outer surface of the push handle 61.
[0023] It should be noted that one end of the support leg 3 is rotatably connected to the reducer mounting base 5 via the rotating seat 30. The reducer 8 is located between the rotating seat 30 and the reducer mounting base 5, and its output end is engaged with the rotating seat 30. The transmission shaft 6 passes through the rotating seat 30 and is connected to the reducer 8. When the output end of the reducer drives the support leg 3 to fold, the support leg and the U-shaped handle can be folded together.
[0024] It should also be noted that the reducer mounting seat 5 is connected to the rear wheel seat 2 via an elastic element 9, so that the entire frame has a good shock absorption effect, making it more comfortable for infants and toddlers to ride in the stroller.
[0025] In this embodiment, the reducer mounting base 5 is also rotatably connected to the U-shaped handle 4 via a linkage 50, so that the entire frame can be folded.
