Detailed Description

The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.

As shown in fig. 1 to 3, the child vehicle with the rotation preventing function of the vehicle head of the present invention comprises: the bicycle frame comprises a bicycle frame 1, a front wheel assembly 2, a rear wheel assembly 3 and an anti-rotation mechanism 4.

The front wheel assembly 2 is provided with a connecting rod 5, and the connecting rod 5 is rotatably arranged at the front end of the frame 1; the rear wheel assembly 3 is arranged at the rear end of the frame 1; prevent that favourable turn 4 sets up the lower extreme at frame 1, prevent being equipped with telescopic link 6 on favourable turn 4, 6 one end activities of telescopic link lean on connecting rod 5.

When the child car is pushed, the telescopic rod 6 abutted against the connecting rod 5 can fix the connecting rod 5, so that the connecting rod 5 cannot rotate relative to the car frame 1 in the pushing process, and the child car can also control the advancing direction of the child car when pushed behind the car even if the child who takes does not hold the handlebar.

In order to enable the telescopic rod 6 to prevent the head of the baby carriage from swinging during pushing and not to influence normal riding of the baby carriage, the scheme is provided with two sets of anti-rotation mechanisms 4, and specific contents of the scheme are described through two specific embodiments.

Example one

Prevent still including the driving piece of the motion of drive telescopic link 6 on the favourable turn 4, driving piece detachable sets up on frame 1, and the cylinder, step motor or electro-magnet can be chooseed for use to the driving piece.

When a seated child rides normally, the driving piece controls the telescopic rod 6 to retract, and at the moment, the connecting rod 5 can normally rotate around the frame 1; when the child's bike needs to be pushed, the driving piece controls the telescopic rod 6 to pop out, one end of the telescopic rod 6 abuts against the connecting rod 5, the connecting rod 5 cannot rotate around the bike frame 1 under the action of the telescopic rod 6, and the child's bike pushed behind the bike can also control the advancing direction of the child's bike.

Example two

As shown in fig. 2, the anti-rotation mechanism 4 further comprises a housing 7, a movable groove 8 is arranged inside the housing 7, an opening 11 communicated with the movable groove 8 is formed in the side wall of one end of the housing 7, one end of the telescopic rod 6 penetrates through the opening 11 and is movably arranged in the movable groove 8, an elastic part 9 for driving the telescopic rod 6 to move is arranged in the movable groove 8, the number of the movable grooves 8 is consistent with that of the telescopic rods 6, the number of the telescopic rods 6 can be one, two or more, and in the scheme, the detailed description is mainly carried out on the condition that two telescopic rods 6 are arranged.

Spring, rubber or sponge can be selected to elastic component 9, and the details are carried out to elastic component 9 under the condition of chooseing for use the spring in this scheme mainly, because rubber or sponge have the same operating condition with the spring when using, and this place is no longer repeated.

The spring need guarantee when selecting that promote the perambulator head can not swing, and can not influence normal the turning when children normally ride again, suitable elastic cylinder type spring can be chooseed for use to the spring, after will preventing changeing mechanism 4 and installing on frame 1, no matter be in the state of normally riding or pushing, telescopic link 6 all can lean on connecting rod 5 at its one end under the spring action of spring, the elasticity of spring can make connecting rod 5 keep forward state under the condition of not exerting external force, so that conveniently push away, when normally riding, children exert thrust to connecting rod 5 and drive connecting rod 5 and rotate, can not influence the normal riding of perambulator, and after turning at every turn, the elasticity of spring can make connecting rod 5 return to the original right automatically again, and is more laborsaving. Compared with the driving member in the first embodiment, the driving member in this embodiment is simpler and more practical in structure.

As shown in fig. 3, the shell 7 is provided with a positioning pin 10, the lower end of the frame 1 is provided with a positioning hole, the positioning pin 10 is movably inserted into the positioning hole, and the positioning pin 10 and the positioning hole can be more convenient for positioning and mounting the shell 7.
