For a more complete understanding of the embodiments and their advantages, reference is now made to the following description taken in conjunction with the accompanying drawings, in which: [Fig. 1] is a schematic structural view of a carrier tray stacking assembly according to an embodiment of the present invention; [Fig. 2] is a cross-sectional view taken along the AA section line of [Fig. 1]; [Fig. 3] ] Is a partial cross-sectional view of a carrier tray stacking assembly according to an embodiment of the present invention; [Fig. 4] is an enlarged schematic view of part A of Fig. 1; Fig. 1] is a cross-sectional view taken along the BB section line; and [Fig. 6] is a partial structural schematic diagram showing a position-limiting structure according to another embodiment of the present invention.

Please refer to FIG. 1 and FIG. 2 at the same time. FIG. 1 is a schematic structural view of a carrier tray stacking assembly according to an embodiment of the present invention. FIG. 2 is a cross-sectional view taken along a line A-A in FIG. 1. This embodiment mainly provides a carrier tray 200. The carrier tray 200 is mainly used to carry objects, and the carrier trays 200 can be stacked on each other to form a carrier tray stacking assembly 100. The carrying tray 200 mainly includes a bottom plate 210, a side wall 220, a carrying portion 230, a side plate portion 240, and a plurality of limiting structures 250.

As shown in FIGS. 1 and 2, the bottom plate 210 has a top surface 211 and a bottom surface 212 opposite to the top surface 211. The side wall 220 is erected on the bottom plate 210, and the side wall 220 and the top surface 211 of the bottom plate 210 together form an accommodation space A1, and the accommodation space A1 can be used to accommodate objects. In this embodiment, the sidewall 220 and the bottom plate 210 looks U-shaped in cross section. The bearing portion 230 extends from the upper end of the side wall 220 along the first direction D1, wherein the first direction D1 is defined in a direction away from the accommodation space A1. The side plate portion 240 extends downward from an end of the supporting portion 230 away from the side wall 220. Thereby, the side plate portion 240, the bearing portion 230 and the side wall 220 together form an internal space A2. This internal space A2 is mainly used to accommodate the first abutment structure 310 recessed from the side plate portion 240 and the second abutment structure 320 protruding from the side wall 220 (as shown in FIGS. 3 and 5).

Specifically, please refer to FIG. 1 and FIG. 3, where FIG. 3 is a partial cross-sectional view of a carrier tray stacking assembly according to an embodiment of the present invention. The first abutment structure 310 is a convex structure that is recessed from the outer surface of the side plate portion 240 toward the inner space A2 and is formed on the inner surface of the side plate portion 240. The second abutment structure 320 is a protruding structure formed from the outer surface of the side wall 220 toward the inner space A2. Therefore, as shown in FIG. 3, when the two carrier trays 200 are stacked on each other, the first abutment structure 310 and the second abutment structure 320 of the upper carrier tray 200 abut against the adjacent carrier tray 200 below. On the bearing portion 230. In other words, the supporting portion 230 of the lower supporting plate 200 has a function of supporting the upper supporting plate 200. Moreover, through the design of the first abutment structure 310 and the second abutment structure 320, the structural strength of the side plate portion 240 and the side wall 220 itself can also be increased.

Please also refer to FIG. 1 and FIG. 4 together, where FIG. 4 is an enlarged schematic view of part A of FIG. 1. In this embodiment, each of the limiting structures 250 includes a recessed portion 251 and at least one protruding structure 252. The recessed portion 251 is recessed into the side plate portion 240, and the recessed portion 251 has an open end. The protruding structure 252 protrudes from the position of the recessed portion 251 near the open end along the second direction D2, so that the recessed portion The width W1 of the opening 251a of the recessed portion 251 along the second direction D2 is smaller than the width W2 of the recessed portion 251 along the second direction D2. The second direction D2 is different from the first direction D1. In this embodiment, the second direction D2 is perpendicular to the first direction D1. That is, the second direction D2 is defined in a direction perpendicular to a direction away from the accommodation space A1.

Please refer to FIG. 4 and FIG. 5, where FIG. 5 is a cross-sectional view taken along a line B-B in FIG. 1. In this embodiment, the surface of the protruding structure 252 facing the internal space A2 and the side plate portion 240 together form an engaging space A3. When the two carrier trays 200 are stacked on each other, the protruding structure 252 of the lower carrier tray 200 is embedded in the engaging space A3 of the upper adjacent carrier tray 200. Thereby, the protruding structure 252 of the limiting structure 250 of the upper tray 200 can restrict the protruding structure 252 of the limiting structure 250 of the lower tray 200 from deforming due to the weight of the object, thereby avoiding the lower bearing The side wall 220 of the disk 200 expands outward in a direction away from the accommodating space A1 (that is, the first direction D1). Specifically, as shown in FIG. 5, because a part of the protruding structure 252 of the lower carrier tray 200 is caught by the protruding structure 252 of the upper carrier tray 200, when the lower carrier tray 200 is subjected to a large downward movement, When the pressure causes the sidewall 220 to expand outward, the protruding structure 252 and the sidewall 220 of the upper tray 200 can simultaneously block the expansion of the sidewall 220 of the lower tray 200 at the same time.

The limiting structure of the present invention can also have different designs. Please refer to FIG. 6, which is a schematic diagram showing a partial structure of a limiting structure according to another embodiment of the present invention. A post structure 410 is provided on the bottom surface of the limiting structure 400 in this embodiment. Therefore, please refer to FIG. 1 as well. During stacking, the pillar structure 410 of the lower carrier tray abuts against the bottom surface of the limiting structure 400 of the upper adjacent carrier tray, so as to improve the stability of the stack.

It can be known from the foregoing that the limiting structure of the present invention has a design of a recessed portion and a protruding structure. When the trays are stacked on each other, the protruding structure of the upper tray can limit the protruding structure of the lower tray due to the weight of the object. Deformation is generated, thereby avoiding the problem of expansion of the side wall of the underlying tray. In addition, the first abutment structure and the second abutment structure respectively provided on the side plate portion and the side wall can not only help the upper tray to be stable on the bearing portion of the lower tray, but also strengthen the side plate portion and the side wall itself. Structural strength.

Although the present invention has been disclosed as above with the examples, it is not intended to limit the present invention. Any person with ordinary knowledge in the technical field can make some modifications and retouching without departing from the spirit and scope of the present invention. The protection scope of the present invention shall be determined by the scope of the attached patent application.
