Hereinafter, the terms used in the description of the embodiments according to the present invention, such as the description of orientational or positional relationships indicated by “up”, “down”, and the like, are described according to the orientational or positional relationships shown in the figures used. The above terms are merely for the convenience of describing rather than limiting the present invention, that is to say, they do not indicate or imply that the element mentioned must have a specific orientation or be constructed in a specific orientation. In addition, the terms “first”, “second”, and the like mentioned in this specification or the scope of the patent application are only used to name the elements or distinguish different embodiments or scopes, rather than to limit the upper or lower limit of the number of elements.

FIG.1is a schematic three-dimensional view of an embodiment of a tray in the present invention.FIG.2is a schematic diagram of separation of one limit block from a surrounding wall inFIG.1.FIG.3Ais a schematic diagram of use during separation of the limit block of the tray inFIG.1.FIG.3Bis a schematic diagram of use of the tray inFIG.1. Referring toFIG.1toFIG.3B, a tray1in this embodiment includes a bottom plate2, a surrounding wall3, and a plurality of limit blocks4. The surrounding wall3surrounds a periphery of the bottom plate2. A plurality of protrusions31are arranged on an inner side of the surrounding wall3. The limit blocks4are adapted to be separably assembled on the bottom plate2, and each of the limit blocks4has a limit groove41and a limit portion42. The limit groove41is adapted to be clamped with one of the protrusions31. The limit portion42is positioned on an opposite side of the limit groove41.

Refer toFIG.3AandFIG.3B. Through the above design, during use, a user may select whether the limit blocks4are assembled on the protrusions31as needed to generate different sizes of accommodating spaces (an accommodating space S1surrounded by a dashed line inFIG.3Aand an accommodating space S2surrounded by a dashed line inFIG.3B; and to clearly represent a contour of the accommodating space S2, some features on the limit blocks4in this embodiment are omitted) by cooperation with the surrounding wall3or the limit portions42on the bottom plate2, so as to correspond to sizes of bearing objects placed on the tray1, without redesigning the entire tray1. In addition, a shape of each of the limit blocks4in the figure is only for illustration. During actual use, various different limit blocks4may be designed as needed, or the limit blocks4are mounted on the protrusions31at other positions on the figure to generate various different accommodating spaces.

FIG.4Ais a schematic three-dimensional view of a front surface of the limit block inFIG.1.FIG.4Bis a schematic three-dimensional view of a back surface of the limit block inFIG.1.FIG.4Cis a schematic view of a section A-A of the tray inFIG.1. Referring toFIG.1,FIG.2, andFIG.4AtoFIG.4C, in this embodiment, a shape of the bottom plate2corresponding to a product is, for example, a rectangle. For the number of the protrusions31on the surrounding wall3, for example, when the surrounding wall3surrounds the bottom plate2, there are two protrusions on a short side of the rectangle and three protrusions31on a long side of the rectangle, and each of the protrusions31has the same shape and size. The shape of the bottom plate2and the number and positions of the protrusions31are not limited, and may be set according to the shape of the product corresponding to the tray1.

Refer toFIG.2,FIG.3A, andFIG.3B. In this embodiment, each of the limit blocks4is of a thin shell structure, for example, and has an opening40in a side facing the bottom plate2. A shape of the limit portion42is, for example, a partial contour shape (such as a straight line) corresponding to the accommodating space S2. Each of the limit blocks4has, for example, an outer flange43extending from the limit portion42. The outer flange43is, for example, arranged by the limit portion42extending along the opening40to two sides of the limit groove41and avoiding a part where the corresponding limit block4contacts with the surrounding wall3. Therefore, during combination, each surface of the limit groove41can contact the corresponding protrusion31.

With respect to relevant design of combination between the limit groove41and the corresponding protrusion31, in this embodiment, firstly, the limit groove41has, for example, a groove hole411and a bottom412opposite to the groove hole411, and has a pair of limit walls413opposite to each other between the bottom412and the groove hole411. Each of the limit walls413has a first limit structure414a. The first limit structure414ais adapted to be combined with a second limit structure31apositioned on the corresponding protrusion31and arranged corresponding to a position of the first limit structure414a. The bottom412has a third limit structure. The third limit structure is adapted to be combined with a fourth limit structure positioned on the corresponding protrusion31and arranged corresponding to a position of the third limit structure. The first limit structure414ais, for example, a convex point protruding from the corresponding limit wall413, while the second limit structure31ais, for example, a corresponding concave hole (seeFIG.2), the third limit structure is, for example, a limit bulge414b(such as the convex point, seeFIG.4A) protruding from a surface of the bottom413, and the fourth limit structure is, for example, a corresponding limit recess31b(such as the concave hole, seeFIG.2).

The first limit structure414amay, for example, have a distance d2from an edge of either side of the corresponding limit wall413and is, for example, positioned in a center of the corresponding limit wall413. During assembly, for example, by means of elastic deformation of the corresponding limit block4, the first limit structure414aand the second limit structure31acan be clamped with each other, without the limitation that they must be combined in a unique specific direction to be clamped with each other.

During assembly, for example, the limit blocks4may be combined with the protrusions31in a direction d1perpendicular to the bottom plate2(as shown inFIG.1andFIG.2), or may be combined with the protrusions31by moving upward along a plane of the bottom plate2, or may be combined with the protrusions31at an angle of inclination to the bottom plate2to have a plurality of assembly directions. After combination, for the limit blocks4and the surrounding wall3, the limit blocks4are prevented from being separated from the surrounding wall3along the periphery of the bottom plate2via the protrusions31and the limit grooves41, and the limit blocks4are prevented from being separated from the surrounding wall3along openings of the groove holes411by clamping the first limit structures414aand the second limit structures31a.

Refer toFIG.1,FIG.2, andFIG.4AtoFIG.4C. In this embodiment, for example, the bottom plate2has a plurality of grooves21. The grooves21are adjacent to the protrusions31, respectively. A contour of each of the grooves21corresponds to a contour of each of the limit blocks4(for example, corresponds to a contour of the outer flange43), where a depth21aof each of the grooves21is, for example, equal to a thickness t of the outer flange43, such that a surface of the outer flange43and a surface of the bottom plate2after assembly present a continuous plane (seeFIG.4C). In addition, in the direction d1perpendicular to the plane of the bottom plate2, each of the limit blocks4has a height that is, for example, a height of the corresponding protrusion31in the same direction d1, to present a continuous plane with a top surface of the surrounding wall3.

Next, refer toFIG.1,FIG.2, andFIG.4AtoFIG.4C. In this embodiment, a positioning groove211is further arranged in each of the grooves21, and a positioning bump431adapted to be mounted on the positioning groove211is arranged on the outer flange43. In this embodiment, the positioning bump431is, for example, positioned on the outer flange43on an opposite side of the groove hole411of the limit groove41. Therefore, after the limit blocks4are combined with the protrusions31, the positioning bumps431will enter the positioning grooves211and prevent the limit blocks4from being separated from the protrusions31along the groove holes411.

In conclusion, the tray in the present invention can form storage spaces corresponding to products of different sizes by assembling and connecting the limit blocks, so as to correspond to parts of different sizes. In addition, since the service life of the same tray can be prolonged by arranging the plurality of limit blocks with different sizes and smaller relative volumes, the inconvenience in storage and production is reduced.
