AI Technical Summary
Existing folding panels are prone to wobbling and instability when unfolded, affecting the user experience and load-bearing capacity.
By setting a locking block and a latch in a cooperating structure on the folding plate, the locking block and latch are stacked when unfolded. The latch slides to prevent the locking block from disengaging from the stacked relationship and prevent the folding plate from rotating. The latch and locking block are located on the inner wall surface to avoid the latch protruding and optimize the product structure.
It improves the stability and load-bearing capacity of the folding panel, increases the contact area of the shopping cart, optimizes the product's appearance, and reduces shaking.

Abstract
Claims
1. A folded panel assembly, characterized by It includes a first folding plate and a second folding plate, which are rotatably connected to allow the first folding plate and the second folding plate to be unfolded or folded. The first folding plate is provided with a locking block, and the second folding plate is also slidably provided with a latch. When the first folding plate and the second folding plate are unfolded, the locking block is stacked with the second folding plate, and the latch slides toward the locking block to prevent the locking block from disengaging from the stacked relationship with the second folding plate.
2. The folded sheet assembly of claim 1, wherein, The second folding plate is provided with a slide rail, which extends along the height direction of the second folding plate; the latch includes a baffle and a slider, the baffle is fixedly connected to one side of the slider, and the slider slides in cooperation with the slide rail. When the first folding plate and the second folding plate are unfolded, the slider slides and drives the baffle to move toward the locking block to prevent the locking block from disengaging from the stacking relationship with the second folding plate.
3. The folded sheet assembly of claim 2, wherein, One end of the slide rail is provided with a limiting protrusion, which is used to prevent the slider from falling off.
4. The folded sheet assembly of claim 3, wherein, The limiting protrusion is provided with a first guide slope, and one end of the slider along the sliding direction is provided with a first mating slope. The slider is installed on the slide rail by the contact and pressing of the first guide slope and the first mating slope.
5. The folded sheet assembly of claim 2, wherein, The slider has a cavity and an opening communicating with the cavity. When the slider is installed, the slide rail enters the cavity through the opening, allowing the slider and the slide rail to slide together. The slide rail has a second guide slope and the slider has a second mating slope. The second mating slope is located at the opening. The slide rail enters the cavity from the opening by contacting and pressing the second guide slope and the second mating slope.
6. The folded sheet assembly of claim 2, wherein, The slider is provided with anti-slip texture.
7. The folded sheet assembly of claim 1, wherein, The latch slides along the height direction of the second folding plate; the locking block is provided with a contact surface, which supports the latch when the latch stops the locking block from disengaging from the stacking relationship with the second folding plate.
8. The folded sheet assembly of claim 7, wherein, The lock block is provided with a slot, the bottom surface of which is the contact surface. When the latch stops the lock block from disengaging from the second folding plate, one end of the latch is located in the slot.
9. The folded sheet assembly of claim 1, wherein, The second folding plate is also fixedly provided with a limiting protrusion. When the buckle slides to contact the limiting protrusion, the force on the buckle is removed, and the limiting protrusion can prevent the buckle from sliding.
10. A folding shopping cart, characterized by, The folding cart includes a folding panel assembly as described in any one of claims 1-9, wherein there are two folding panel assemblies, one of which is disposed opposite to the other along one direction of the folding shopping cart; the folding shopping cart further includes a front panel, a rear panel, and a bottom panel, wherein the front panel and the rear panel are disposed opposite to each other along another direction of the folding shopping cart; the folding shopping cart includes a receiving cavity, wherein the inner wall surfaces of the folding panel assemblies, the front panel, the rear panel, and the bottom panel constitute at least a portion of the wall surfaces corresponding to the receiving cavity; the latch and the locking block are both disposed on the inner wall surfaces of the folding panel assemblies.
