The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings and specific embodiments. As shown in fig. 1-6, a frame folding mechanism of a stroller for strolling a child comprises two leg components: the joint support is characterized by further comprising a large joint assembly, wherein the large joint assembly comprises a joint support 3, the joint support 3 and any one of the leg assemblies are fixed and are in rotating connection with the other leg assembly, the leg assembly in rotating connection with the joint support 3 is a first leg assembly 1, and the other leg assembly is a second leg assembly 2; a seat panel 4 is connected above the joint frame 3; a first linkage piece 5 is hinged between the seat panel 4 and the leg component which is rotatably connected with the joint frame 3; a locking mechanism is arranged between the seat panel 4 and the joint frame 3; when the locking mechanism is locked, the seat panel 4 is fixed above the closing rack; when the locking mechanism is unlocked, the two leg assemblies are respectively a front leg assembly and a rear leg assembly. The front leg assembly includes a front leg and two front wheels disposed on the front leg. The rear leg assembly comprises a rear leg and a rear leg assembly arranged on the rear leg. The first leg assembly 1, which is pivotally connected to the knuckle mount 3, may be a front leg assembly or a rear leg assembly. In the present invention, when the frame is unfolded, the seat panel 4 and the knuckle mount 3 are fixed together by the locking mechanism, and can be regarded as a single member, and a triangular stable structure is formed between the seat panel, the first leg assembly 1 and the first linkage piece 5. After the locking mechanism is unlocked, the seat panel 4 and the joint frame 3 are not fixed any more, and an unstable link mechanism is formed among the seat panel 4, the joint frame 3, the first leg assembly 1 and the first linkage piece 5. The first leg assembly 1 can be rotated relative to the articulated frame 3, which can be folded up. After the locking mechanism is unlocked, the frame is lifted, and the first leg component 1 is automatically folded due to gravity, so that the folding and unfolding are convenient. A connecting piece can be fixedly arranged on the first leg component 1, and the connecting piece is rotatably connected with the joint frame 3.

A second linkage sheet 6 is hinged between the joint frame 3 and the seat panel 4, and the seat panel 4 is connected above the joint frame 3 through the second linkage sheet 6; when the locking mechanism is unlocked: a five-link mechanism is formed among the seat panel 4, the second link 6, the joint frame 3, the first leg assembly 1, and the first link 5. In the locked state, the seat panel 4 and the knuckle mount 3 are fixed together by the locking mechanism, and the position of the second link piece 6 is not changed. In the five-link mechanism, there is a greater chance of selecting the position of the seat panel 4. Of course, the link mechanism may have more links such as a six-link mechanism.

A locking sliding groove 7 is arranged in the joint frame 3, and the locking mechanism comprises a locking piece 8 which is arranged in the locking sliding groove 7 in a front-back sliding mode and a pull belt 8 connected with the locking piece 8; one end of the pull belt 8 extends out of the joint frame 3; a first return spring is arranged between the locking piece 8 and the joint frame 3, so that the locking piece 8 automatically returns to a locking position; the locking member 8 moves forward and backward to switch between locking and unlocking with the seat panel 4. (the shape of the locking sliding groove 7 enables the locking piece 8 to move back and forth to play a limiting role, the locking mechanism has simple structure, the locking can be unlocked by pulling the drawstring 8, and the locking mechanism can automatically reset.)

A slot 40 is provided in the seat panel 4, and when the locking member 8 is located at the locking position, one end of the locking member 8 is inserted into the slot 40. The locking between the locking element 8 and the seat panel 4 can be implemented in other, e.g. conventional, locking manners. Of course, the locking member 8 may be provided with the insertion groove 40, and the seat panel 4 may be inserted into the insertion lock of the locking member 8 to be locked. When the seat is unlocked, the pull belt 8 is pulled to move outwards, the locking piece 8 moves outwards and is moved out of the slot 40, and the seat panel 4 and the joint frame 3 are unlocked.

The locking device further comprises a second locking mechanism, wherein the second locking mechanism comprises a second locking piece 10 arranged in the locking sliding groove 7; a second reset spring is arranged between the two locking pieces 10 and the joint frame 3, the two locking pieces 10 are connected with two lock buttons positioned outside the joint frame 3, and after the two locking pieces 10 move downwards, the locking pieces 8 can move back and forth to be unlocked. The two lock mechanisms are arranged, so that the locking mechanism can prevent children or other hands from being touched by mistake, and the safety is higher. The second locking member 10 of the second locking mechanism may be L-shaped, wherein a longer side may be provided with a groove as the second locking button, and a shorter side may be moved downward to give a space for the locking member 8 to move backward. When the locking mechanism is unlocked, the locking piece 8 moves forwards to unlock or moves backwards to unlock, depending on whether the locking mechanism is installed at the front end or the rear end of the joint frame 3. Typically, the first leg assembly 1 that can rotate can be a rear leg assembly, and the locking mechanism and the second locking mechanism are mounted at the rear end of the knuckle mount 3. The non-rotatable second leg assembly 2 may be a front leg assembly. The structures of the first leg assembly 1 and the second leg assembly 2 are not the point of the utility model and will not be described in detail.

In the specific implementation: when unlocking is required: first, the two-way lock button is pressed down, so that the two-way locking member 10 moves down to give the locking member 8 a space to move backward. Then, the pulling strip 8 is pulled, the pulling strip 8 drives the locking piece 8 to move backwards, the front end of the locking piece 8 is removed from the slot 40 of the seat panel 4, and the locking mechanism is unlocked. The frame is lifted by the pull straps 8, the first leg components 1 are automatically folded inwards under the action of gravity, and the whole frame is folded.

When the frame needs to be unfolded: pulling the pull strip 8 to move backwards while pulling the second lock button to move downwards, pressing the seat panel 4 downwards and unfolding the first leg assembly 1 until the seat panel 4 presses on the knuckle shelf 3, and releasing the pull strip 8 to lock the locking element 8 with the seat panel 4 under the action of the first return spring.

The features of the embodiments described above may be arbitrarily combined, and the combination of the features is not contradictory, and should be considered as a range described in the present specification. The technical solution according to the present invention and equivalents or changes thereof, as well as several changes and modifications made therein, should also be considered as the protection scope of the present invention without departing from the overall concept of the present invention.
