New Description: [New Technology Field] [0001] [0002] [0003] This creation is about a baby carriage, especially a folding mechanism, a single-step double brake structure and a twisting mechanism to enhance the use. Improved infant and stroller structure for safety and convenience. [Prior Art] According to the baby carriage, the baby carriage is an auxiliary vehicle for carrying infants or young children, and the structure includes at least a frame body and a seat disposed on the body of the frame. The frame body mainly includes the front vehicle. The rear frame and the rear frame are respectively provided with a front wheel set and a rear wheel set; in addition, a handle portion for the user to support is connected at the upper end of the front frame, and the rear frame is folded by a joint structure. The connection with the front frame forms a joint structure to expand or fold the stroller, thereby saving storage space. Moreover, with the advancement of the process technology, in order to improve the convenience of the use of the stroller, many manufacturers have improved the components of the stroller. Currently, the one-handed folding stroller that is commonly available on the market is set in the handlebar. A control button drives the interlocking member disposed in the front frame to release the locked state of the folded joint structure by pressing the control button, thereby causing the frame body to be folded; however, since the stroller frames are mostly mutually The pivotal connecting rod and joint have complicated components and many joint points. Once the design is bad, it is easy to cause the child to be pinched, which is the most unpleasant situation for the user. In view of this, the creator has developed and improved the overall structure of the baby carriage, and finally proposed a reasonable design and functional enhancement, and can form the number No. A0101 Page 3 of 37 [0004] M425077 Effectively improve the above-mentioned defects The creation of this. [New content] [0005] The technical problem to be solved in this creation is to overcome the shortcomings of the poor design of the connecting rod and joint of the conventional baby carriage frame. The main purpose of this creation is to provide a one-handed folding and stable structure. The utility model can also improve the structure of the infant stroller with high safety single-step double brake structure and high convenience. [0006] For the purpose of the foregoing creation, the technical problem of the creation is achieved by the following technical solutions. The structural improvement of the infant stroller according to the present invention comprises a frame body and a seat disposed on the frame body, the frame body comprising a front frame, a pair of rear frames, and a a front wheel set at a lower end of the front frame and a rear wheel set disposed at a lower end of the rear frame, the front frame including an upper frame, a pair of folding mechanisms and a pair of lower frames, wherein the upper frame The door is of a gate type, wherein the segment is provided with a folding control device, and the pair of folding mechanisms are respectively disposed at the two ends of the upper frame, and the folding mechanism is connected to the folding control device through a flexible wire. The folding mechanism is provided with a folding joint, and the pair of lower frames are connected with the pair of folding mechanisms, and the pair of rear frames are connected with the folding joint. [0007] The rear wheel set is provided with a toothed hook portion on the inner side of the wheel, and a brake member is respectively disposed on the lower end of the pair of rear frames, and a protruding column is protruded toward the outer side, and one of the brakes is disposed. The brake pedal is pivotally connected with the brake member, and the brake member is coupled with a flexible member. The stepping of the brake pedal enables the protruding post to be snapped to the latch portion of the rear wheel set. , to achieve the effect of a single step on the double brake. Form No. A0101 Page 4 of 37 [0008] The seat has an outer frame, the outer frame is provided with a control handle at the upper end, and a pivoting mechanism corresponding to each other is provided on both sides. The pivoting mechanism comprises a first shaft disc, a second shaft disc, a sliding member, a gear member and a spring, which are integrally combined by a fixing member such as a rivet, wherein the first shaft disc is respectively extended toward the front and the rear The first sleeve and the second sleeve are respectively connected to the outer frame, and the first shaft and the second shaft are respectively provided with a first groove and a second groove corresponding to each other, the first groove The ring is provided with a first gear portion, and the second groove ring is provided with a second gear portion. The second socket arm is provided with a sliding slot to communicate with the first groove, and the sliding member is inserted into the sliding slot. The upper end of the sliding member is provided with at least one locking groove, and the lower end is provided with an arcuate groove, and the arcing groove is provided with a long hole at the center thereof, and the gear member is correspondingly engaged with the first gear portion and the second gear portion, The gear member has a shaft hole with an arcuate flange on one side and an inner ring groove on the other side, the arcuate flange and the The slot forms a male-female joint, and the spring is sleeved in the inner ring groove; the control handle includes an upper casing, a lower casing and a grip pivoted between the upper and lower casings, the grip is provided a corresponding recessed groove, the fitting is fitted with a flexible member such as a steel cable, and the other end of the flexible member is fitted into the locking groove of the sliding 4; thereby, the user can twist the grip And causing the flexure to pull the sliding member to force the gear member to disengage from the first gear portion, thereby releasing the twisting mechanism to achieve the effect of adjusting the tilt angle of the seat. [0010] In summary, the present invention has the following advantages: 1. The creation of the frame body can be folded by a single hand pressing the folding control device, which can reduce the volume and save the storage space, and has excellent convenience. Sex. 2. The user does not need to take the infant who has already been seated in the seat to take off the form number A0101. Page 5 of 37 [0011] M425077 [0012] [0014] [0015] [0017] [0017] [0019] [0019] Form No. A0101 The chair can adjust the tilting angle of the seat by twisting the grip to release the locking state of the pole turning mechanism. This structure design is convenient and safe. 3. This creation can be used to make the left and right rear wheels synchronously brake as long as one foot pedals on the brake pedal of the rear wheel group.
