Detailed Description

Referring to fig. 1 and 2, fig. 1 is a schematic structural diagram illustrating a tray stack assembly according to an embodiment of the invention, and fig. 2 is a cross-sectional view taken along a line a-a of fig. 1. The present embodiment mainly provides a carrier tray 200. The carrier tray 200 is mainly used for carrying objects, and the carrier trays 200 can be stacked on each other to form the carrier tray stack assembly 100. The carrier tray 200 mainly includes a bottom plate 210, a sidewall 220, a carrier portion 230, a side plate portion 240, and a plurality of position-limiting structures 250.

As shown in fig. 1 and 2, the bottom plate 210 has a top surface 211 and a bottom surface 212 opposite to the top surface 211. The sidewall 220 is vertically disposed on the bottom plate 210, and the sidewall 220 and the top surface 211 of the bottom plate 210 together form an accommodating space a1, and the accommodating space a1 can be used for accommodating articles. In the present embodiment, the side walls 220 and the bottom plate 210 are U-shaped in cross section. The carrying portion 230 extends from the upper end of the sidewall 220 along a first direction D1, wherein the first direction D1 is defined as a direction away from the accommodating space a 1. The side plate 240 extends downward from an end of the carrier 230 remote from the side wall 220. Thereby, the side plate 240, the carrier 230 and the side wall 220 form an inner space a 2. The inner space a2 is mainly used for accommodating the first abutting structure 310 recessed from the side plate 240 and the second abutting structure 320 protruding from the side wall 220 (as shown in fig. 3 and 5).

Specifically, referring to fig. 1 and fig. 3, fig. 3 is a partial cross-sectional view illustrating a tray stack assembly according to an embodiment of the invention. The first abutting structure 310 is a convex structure formed on the inner surface of the side plate portion 240 recessed from the outer surface of the side plate portion 240 toward the inner space a 2. The second abutting structure 320 is a protruding structure protruding from the outer surface of the side wall 220 toward the inner space a 2. Thereby, as shown in fig. 3, when two carrier trays 200 are stacked on each other, the first abutting structure 310 and the second abutting structure 320 of the upper carrier tray 200 abut against the carrying portion 230 of the lower adjacent carrier tray 200. That is, the carrying portion 230 of the lower carrier tray 200 has a function of supporting the upper carrier tray 200. Moreover, the first abutting structure 310 and the second abutting structure 320 are designed to increase the structural strength of the side plate 240 and the side wall 220.

Referring to fig. 1 and fig. 4 together, fig. 4 is an enlarged schematic view of a portion a of fig. 1. In the present embodiment, each of the position-limiting structures 250 includes a concave portion 251 and at least one convex structure 252. The recess 251 is recessed into the side plate 240, and the recess 251 has an open end. The protruding structure 252 protrudes from the concave portion 251 near the open end along the second direction D2, such that the width W1 of the opening 251a of the concave portion 251 along the second direction D2 is smaller than the width W2 of the concave portion 251 along the second direction D2. Wherein the second direction D2 is different from the first direction D1. In the present embodiment, the second direction D2 is perpendicular to the first direction D1. That is, the second direction D2 is defined as a direction perpendicular to the direction D1 away from the accommodating space a 1.

Referring to fig. 4 and 5, fig. 5 is a cross-sectional view taken along line B-B of fig. 1. In the present embodiment, the surface of the protruding structure 252 facing the internal space a2 forms a clamping space A3 together with the side plate 240. When two carrier trays 200 are stacked on top of each other, the protruding structures 252 of the lower carrier tray 200 are inserted into the engaging spaces a3 of the adjacent carrier tray 200. Therefore, the protruding structure 252 of the position-limiting structure 250 of the upper tray 200 can limit the deformation of the protruding structure 252 of the position-limiting structure 250 of the lower tray 200 caused by the weight of the articles, thereby preventing the sidewall 220 of the lower tray 200 from expanding outward along the direction away from the accommodating space a1 (i.e., the first direction D1). Specifically, as shown in fig. 5, since a portion of the protruding structure 252 of the lower tray 200 is covered by the protruding structure 252 of the upper tray 200, when the lower tray 200 is subjected to a large downward pressure and the sidewall 220 is about to expand, the protruding structure 252 and the sidewall 220 of the upper tray 200 can simultaneously block the sidewall 220 of the lower tray 200 from expanding.

The limiting structure of the invention can also have different designs. Fig. 6 is a schematic partial structure diagram illustrating a position limiting structure according to another embodiment of the invention. The bottom surface of the stopper structure 400 of the present embodiment is provided with a pillar structure 410. Therefore, referring to fig. 1, when the carrier trays 200 are stacked, the column structure 410 of the lower carrier tray abuts against the bottom surface of the position-limiting structure 400 of the upper adjacent carrier tray, so as to achieve the purpose of improving the stability of the stack.

Therefore, the limiting structure of the present invention has the design of the concave portion and the convex structure, so that when the bearing trays are stacked, the convex structure of the upper bearing tray can limit the deformation of the convex structure of the lower bearing tray caused by the weight of the bearing object, thereby avoiding the problem of outward expansion of the side wall of the lower bearing tray. In addition, the first abutting structure and the second abutting structure respectively arranged on the side plate part and the side wall can not only help the upper bearing plate to be firmly fixed on the bearing part of the lower bearing plate, but also strengthen the structural strength of the side plate part and the side wall.

Although the present invention has been described in connection with the above embodiments, it is not intended to limit the present invention. Numerous modifications and adaptations thereof may be made by those skilled in the art without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
