Description

Technical Field

[0001] This utility model belongs to the field of children's products technology, and in particular relates to a children's tricycle. Background Technology

[0002] Children's tricycles are a common means of entertainment and transportation for children. With economic development and improved living standards, people's demand for children's toys is increasing. A wide variety of toy cars are available on the market, striving to meet the playability and fun requirements of different families.

[0003] A search revealed a children's tricycle with patent publication number "CN103625588A," comprising a frame and a seat. A support column is connected to the rear of the frame, and a horizontal axle is connected to the bottom of the support column. Rear wheels are mounted on both ends of the horizontal axle. A front wheel is mounted on the front of the frame, and foot pedals are mounted on the sides of the frame. A handlebar is mounted on the front of the frame. The seat back has a cushion, and a recessed area is formed on the upper surface of the seat. A push rod is connected to the upper part of the seat, with the middle of the push rod connected to the flat handlebar and the upper end connected to a sunshade. When a child sits on the seat with their feet on the foot pedals, the mother can hold the flat handlebar and push the child out, while the child can also ride the tricycle independently on the foot pedals, getting outdoor exercise with high safety.

[0004] The above technical features have the following shortcomings: children grow quickly, the vehicle's adjustment function is not flexible enough, and it cannot well adapt to children's different sitting posture needs and physical development stages, leading to the premature obsolescence of the vehicle; the T-shaped push bar at the rear of the tricycle has poor stability when pushed, especially when encountering uneven road surfaces, it is easy to tilt to the side.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 A children's tricycle includes a connecting mechanism 1, which includes a frame 101. The front end of the frame 101 is connected to a steering mechanism 2 via an adjustable pin 201, and the rear end is connected to a foldable support mechanism 3 via a movable shaft 301. The frame 101 is provided with a load-bearing mechanism 4, which includes a seat cushion 401 and double-sided push rods 402.

[0025] In this embodiment: a connecting groove 103 is provided at the front end of the frame 101, a through hole 102 is provided on the top surface of the connecting groove 103, and a limiting groove 104 is provided at the rear end of the frame 101.

[0026] In this embodiment: A plurality of threaded holes 202 are equidistantly formed at the top of the pin 201. The pin 201 is rotatably connected to a connecting seat 204 via a rotating shaft 203. A front wheel frame 205, which can rotate relative to the connecting seat 204, is provided on one side of the connecting seat 204. An extension rod 206 is slidably inserted onto the front wheel frame 205. A steering handle 207 is provided at the top of the extension rod 206. A front wheel 208 is installed at the bottom of the front wheel frame 205. Foot pedals can be installed on both sides of the front wheel 208. The pin 201 is slidably inserted into the connecting groove 103. Furthermore, it is fixedly connected to the frame 101 by bolts passing through the through hole 102 and threaded hole 202. When the vehicle needs to be adjusted according to the child's height, the bolt is unscrewed from the threaded hole 202, the pin 201 is pulled out along the connecting groove 103 for a certain length, and then the bolt passes through the through hole 102 and is screwed into the corresponding threaded hole 202 to complete the fixation of the pin 201 to the frame 101. Then the extension rod 206 is pulled out along the front wheel frame 205 for a certain length, which is suitable for children to use at different growth stages and increases the service life of the vehicle.

[0027] In this embodiment: A Y-shaped rear wheel frame 302 is provided on the movable shaft 301. The top of the rear wheel frame 302 is slidably connected to the inner wall of the limiting groove 104. The rear wheel 303 is installed at the bottom of the rear wheel frame 302. When the tricycle needs to be folded and stored, the rear wheel frame 302 rotates and folds relative to the main frame 101. The movable shaft 301 rotates in the limiting groove 104. Then, the pin 201 is pulled out from the connecting groove 103 and rotated clockwise around the rotating shaft 203 to put it into the bottom of the connecting seat 204. The folding process is simple and quick and convenient to carry.

[0028] In this embodiment: a handrail 404 is provided on the push rod 402, and a backrest 403 is fixed between the push rods 402 by an adjustable strap. The push rods 402 are rotatably connected to the frame 101 through bearings. A sunshade can be installed between the top of the push rod 402 and the handrail 404. After the flexible backrest 403 is connected to the push rod 402, the backrest 403 can be adjusted backward with the push rod 402, allowing the child to recline or lie flat, so that the child can choose the riding posture according to the actual needs. When an adult pushes the children's tricycle, the force is transmitted through the push rods 402 on both sides of the main frame 101. Compared with T-shaped handles, it will not easily tilt and has better driving stability.

[0029] Working principle: Children grow rapidly, and when vehicle adjustments are needed to accommodate a child's height, the bolt is unscrewed from the threaded hole 202. After the pin 201 is pulled out a certain length along the connecting groove 103, the bolt passes through the through hole 102 and is screwed into the corresponding threaded hole 202, thus securing the pin 201 to the frame 101. Then, the extension rod 206 is pulled out along the front wheel frame 205 to raise the height of the steering handlebar 207, making it suitable for children at different growth stages and increasing the vehicle's lifespan. (The last sentence appears to be incomplete and possibly refers to a different topic.) After connecting the flexible backrest 403, the backrest 403 can be adjusted backward along with the push rod 402, allowing the child to recline or lie flat, so that the child can choose the riding posture according to the actual needs. When the tricycle needs to be folded and stored, the rear wheel frame 302 rotates and folds relative to the main frame 101, the movable shaft 301 rotates in the limiting groove 104, and then the pin 201 is pulled out from the connecting groove 103 and rotated clockwise around the rotating shaft 203 to put it into the bottom of the connecting seat 204. The folding process is simple and quick, and it is convenient to carry.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
