When the cart frame needs to be folded, as shown in fig. 2 and 3, after the locking mechanism is unlocked, the push handle 32 of the push rod frame 3 is folded relative to the push rod 31, and then the push rod frame 3 is driven to turn backwards to gradually fold towards the rear side of the rear support 2, so that the push rod frame 3 rotates relative to the front support 1, the rear part of the seat frame 4 moves towards the push rod frame 3, the distance between the lower end part of the backrest 4 and the push rod frame 3 gradually decreases, and the backrest cloth 81 gradually assumes a released state. Thus, no matter which working gear the backrest 8 is in when the cart frame is unfolded, under the action of the gravity of the backrest 8, the backrest 8 turns backwards and is folded towards the rear bracket 2, and an included angle smaller than 90 degrees is formed between the backrest 8 and the bottom surface of the seat frame 4. At the same time, the connecting rod 7 drives the front accessory 6 to rotate relative to the front bracket 1 and fold towards the front side of the front bracket 1.
Finally, as shown in fig. 4, the front frame 1, the rear frame 2, the putter frame 3, the seat frame 4, the link frame 5, and the backrest 8 are folded together, and the front wheel assembly 10 and the rear wheel assembly 20 are folded together and stand on the ground. Therefore, the trolley frame is simple in structure, convenient to fold and operate, compact in structure after being folded and convenient for daily use of users.
The above embodiments are provided to illustrate the technical concept and features of the present invention and are intended to enable those skilled in the art to understand the content of the present invention and implement the same, and are not intended to limit the scope of the present invention.
