[0035] The technical solution of the present application will be further described below in conjunction with embodiments and drawings.

[0036] Please also read Figures 1 to 3 The embodiment of the present application discloses a tray 100, which includes a tray body 10 and an enclosure 20. The tray body 10 has a first surface 10a and a second surface 10b that are arranged opposite to each other. The first surface 10a is provided with a plurality of spaced receiving grooves 11, and the receiving grooves 11 are used to receive products 200. The enclosure 20 is provided on the first surface 10a and encloses the outer periphery of the receiving groove 11 to form a first receiving cavity 101. The first receiving cavity 101 is connected to the receiving groove 11 to receive the product 200 together. The first receiving cavity 101 has an opening 101a, and the direction of the opening 101a is from the second surface 10b to the first surface 10a, and the opening area of ​​the opening 101a is larger than the opening area of ​​the receiving groove 11.

[0037] The pallet 100 provided in the present application is provided with an enclosure portion 20 on the first surface 10a of the pallet 100, and the enclosure portion 20 is used to enclose the outer periphery of the receiving groove 11 to form a first cavity 101 that is connected to the receiving groove 11 to jointly accommodate the product 200. Since the area of ​​the opening 101a of the first cavity 101 is larger than the area of ​​the receiving groove 11, it is possible to avoid jamming when placing the product 200, so that the product 200 can be placed in the receiving groove 11, which is beneficial to the smoothness of the product 200 placement process and further improves the transportation efficiency of the product 200.

[0038] It can be understood that the above-mentioned receiving groove 11 is used to carry the product 200, so the area of ​​the receiving groove 11 can be adapted to the size of the product 200, and because the area of ​​the opening 101a of the first cavity 101 is larger than the area of ​​the receiving groove 11, it means that the area of ​​the opening 101a of the first cavity 101 can be sufficient to accommodate the product 200. In the process of placing the product 200 from the opening of the first cavity 101 to the receiving groove 11, it can avoid the product 200 colliding with the enclosure 20, or having a large interference with the enclosure 20 to cause a jam, thereby achieving smooth placement of the product 200.

[0039] Optionally, the above-mentioned product 200 may include but is not limited to camera products 200 such as camera modules, mobile phone lenses, motors, or components of electronic products 200 such as circuit boards and batteries. Taking the above-mentioned product 200 as a mobile phone lens as an example, the mobile phone lens may include a base and a lens connected to the base, in which case the base portion may be located in the receiving groove 11, and the lens portion may be located in the first receiving cavity 101.

[0040] See also Figure 2 and Figure 3In order to achieve that the area of ​​the opening 101a of the first cavity 101 is larger than the area of ​​the receiving groove 11, in some possible embodiments, the enclosure 20 is provided with a sink 201, which is located in the first cavity 101 and is arranged around the receiving groove 11. By providing the sink 201 connected to the first cavity 101 on the enclosure 20, the area of ​​the opening 101a of the first cavity 101 can be larger than the area of ​​the receiving groove 11, avoiding the jamming phenomenon when the product 200 is placed, so as to facilitate the placement of the product 200 in the receiving groove 11. In addition, the use of the sink 201 is conducive to the subsequent installation of the protective cover 30, and better provides protection for the product 200.

[0041] In another possible implementation, in order to achieve that the area of ​​the opening 101a of the first cavity 101 is larger than the area of ​​the accommodating groove 11, the side wall surface 301b of the enclosure portion 20 facing the first cavity 101 can be set as an inclined surface, so that the diameter of the first cavity 101 gradually decreases from top to bottom. In this way, not only can the area of ​​the opening 101a of the first cavity 101 be made larger than the area of ​​the accommodating groove 11 to avoid jamming when the product 200 is placed, so as to facilitate placement of the product 200 in the accommodating groove 11, but the inclined surface can also provide guidance for the placement of the product 200, thereby making it more conducive to placing the product 200 in the accommodating groove 11.

[0042] For some embodiments, please refer to Figure 2 The enclosure 20 may include a plurality of first protrusions 21, which are arranged at intervals with the receiving groove 11 as the center and enclose the first receiving cavity 101, a notch 202 is formed between two adjacent first protrusions 21, and the sink 201 is formed on the first protrusion 21. That is, the enclosure 20 may not be continuously surrounded by the outer periphery of the receiving groove 11, but a plurality of first protrusions 21 are arranged at intervals to form the notch 202. In this way, on the basis of being able to achieve the function of accommodating the product 200 together with the receiving groove 11, the weight of the tray 100 can be reduced, thereby making the tray 100 lighter.

[0043] In addition, since the enclosure 20 can be formed by a plurality of first protrusions 21 arranged at intervals, relative to the arrangement of the enclosure 20 continuously surrounding the outer periphery of the receiving groove 11, the enclosure 20 will be more likely to deform to a certain extent under the action of force. In this way, in the process of placing the product 200 in the receiving groove 11, even if the product 200 is at least partially in contact with the enclosure 20, under the action of force, the enclosure 20 can be slightly deformed outside the receiving groove 11, thereby making it easier for the product 200 to be placed in the receiving groove 11.

[0044] Optionally, the number of the first protrusions 21 may be three, four, six, etc., and the plurality of first protrusions 21 may be evenly distributed around the receiving groove 11 .

[0045] In addition, the above-mentioned receiving groove 11 can be a square groove, which can be more suitable for the needs of the product 200 being a camera module, a mobile phone lens, etc., so that the tray 100 is more specialized. At this time, the number of the first protrusions 21 can be preferably four, and the four first protrusions 21 are respectively located at the corners of the square receiving groove 11, so that the arrangement of the first protrusions 21 is more reasonable and beautiful.

[0046] During the production, processing, transportation or packaging of the product 200, in order to facilitate the stacking of the pallet 100, please refer to Figure 4 and Figure 5 , a plurality of grooves 12 are provided on the second surface 10b at positions corresponding to the receiving grooves 11, a plurality of second protrusions 102 are provided on the bottom wall of the grooves 12, the plurality of second protrusions 102 are respectively provided at positions corresponding to the plurality of notches 202, the plurality of second protrusions 102 enclose a second receiving cavity 103, the second protrusions 102 are configured to be embedded in the notches 202 of another tray 100, and the second receiving cavity 103 is configured to at least partially overlap with the first receiving cavity 101 of another tray 100. By embedding the second protrusions 102 in the notches 202 of another tray 100, the structures of the two adjacent trays 100 avoid each other, and the mutual interlocking of the partial structures of the two trays 100 is achieved, thereby enhancing the stacking strength of the two trays 100.

[0047] In addition, by forming a groove 12 corresponding to the receiving groove 11 on the second surface 10b, and arranging the second protrusion 102 on the groove bottom wall of the groove 12, on the one hand, the weight of the tray 100 can be reduced, making the tray 100 lighter; on the other hand, when the tray 100 is stacked with another tray 100, the enclosure 20 of the other tray 100 can be completely accommodated in the groove 12, specifically, the first protrusion 21 is completely located in the groove 12, the gap 202 between the first protrusions 21 just accommodates the second protrusion 102, and the second cavity 103 overlaps with the first cavity 101 at least partially, so that there can be no gap between the two trays 100, thereby reducing the stacking height between the trays 100. At the same time, the side wall surface 301b of the groove 12 can provide a limiting effect on the first protrusion 21 of the other tray 100, thereby preventing the trays 100 from sliding relative to each other.

[0048] In some possible embodiments, a plurality of accommodating grooves 11 are arranged at intervals along the first direction X and the second direction Y, respectively. A plurality of weight-reducing grooves 13 are further arranged on the first surface 10a between two adjacent accommodating grooves 11 along the first direction X. The plurality of weight-reducing grooves 13 are arranged at intervals along the second direction Y. It can be understood that the accommodating grooves 11 on the pallet 100 are usually arranged in rows and columns. In this case, the first direction X can be the row direction, and the second direction Y can be the column direction, that is, a plurality of weight-reducing grooves 13 are further arranged between two adjacent columns of accommodating grooves 11. The plurality of weight-reducing grooves 13 are arranged at intervals in the column direction. The arrangement of the weight-reducing grooves 13 can separate each column of accommodating grooves 11, making the pallet 100 more aesthetically pleasing, and can reduce the weight of the pallet 100, making the pallet 100 lighter.

[0049] Further, the groove 12 can be extended along the second direction Y, and a convex portion 14 can be formed between two adjacent grooves 12 along the first direction X, and part of the second protrusion 102 can be connected to the convex portion 14. That is, a through groove 12 is provided on the back of each column of accommodating grooves 11, and a convex portion 14 is formed between adjacent grooves 12, and the convex portion 14 is located on the back of each column of weight-reducing grooves 13. At this time, part of the second protrusion 102 can be connected to the convex portion 14, that is, part of the second protrusion 102 is provided on the side wall surface 301b of the groove 12, so that the convex portion 14 can provide a bearing effect on part of the second protrusion 102, thereby improving the connection strength of the second protrusion 102.

[0050] In addition, since a plurality of second protrusions 102 are correspondingly disposed on the back side of each receiving groove 11 , there are two adjacent second protrusions 102 along the second direction Y. To save space and facilitate molding, the two second protrusions 102 can be integrally molded.

[0051] Optionally, the side wall surface of the second protrusion 102 facing the second cavity 103 may be an inclined surface, and the inclined surface may provide a guide when another tray 100 is stacked, so that another tray 100 can be stacked on the tray 100 more smoothly.

[0052] Because the pallets 100 are usually stacked together for transportation when carrying the products 200 for transportation or packaging and delivery, and the products 200 in the pallets 100 are deformed under the action of gravity, the products 200 in the pallets 100 on the next layer may be squeezed. Therefore, in order to prevent the accumulation of multiple sets of pallets 100 from squeezing the products 200 in the bottom layer of the pallet 100, or to prevent the products 200 from shaking and colliding and affecting the appearance of the products 200, in some possible implementations, please refer to Figure 6 and Figure 7The tray 100 may further include a protective cover 30, which is configured to cover and connect to the first cavity 101 to cover the opening 101a. The protective cover 30 has an inner cavity 301. When the protective cover 30 covers the first cavity 101, the inner cavity 301 is communicated with the first cavity 101, so that the product 200 is at least partially located in the inner cavity 301. The protective cover 30 covering the first cavity 101 can surround the product 200, and can prevent the product 200 from being squeezed or detached from the receiving groove 11 to cause a serious collision, thereby achieving effective protection for the product 200.

[0053] Further, in order to avoid interference between the product 200 and the protective cover 30, in some possible embodiments, the inner cavity 301 includes a bottom wall surface 301a and a side wall surface 301b connected to the bottom wall surface 301a, and the bottom wall surface 301a and the side wall surface 301b are configured to have an installation gap 303 with the product 200 located in the inner cavity 301. That is, the size of the inner cavity 301 of the protective cover 30 is larger than the size of the part of the product 200 located in the first cavity 101. If the product 200 is a camera module as an example, that is to say, the diameter of the inner cavity 301 is larger than the outer diameter of the lens. In this way, when the protective cover 30 is installed in the first cavity 101, the protective cover 30 will not easily collide with the product 200, and when installed, the product 200 and the bottom wall surface 301a and the side wall surface 301b of the inner cavity 301 retain the installation gap 303, so as to achieve effective protection of the product 200.

[0054] As can be seen from the foregoing, a sinking platform 201 is provided on the enclosure 20. Based on this, in some possible embodiments, when the protective cover 30 covers the first cavity 101, at least part of the outer peripheral surface of the protective cover 30 can abut against the side of the sinking platform 201, and the bottom surface of the protective cover 30 abuts against the bottom surface of the sinking platform 201. That is, the sinking platform 201 located on the enclosure 20 can serve as a supporting structure for the protective cover 30. Since both the outer peripheral surface and the bottom surface of the protective cover 30 are effectively abutted against the sinking platform 201, reliable support for the protective cover 30 can be achieved.

[0055] It can be understood that the product 200 is located in the receiving groove 11, and the side wall of the receiving groove 11 can limit the radial position of the product 200. In order to further limit the axial position of the product 200, in some possible embodiments, the protective cover 30 can also have a limiting portion 302, which is provided at the end of the protective cover 30 and located in the inner cavity 301. The limiting portion 302 is used to limit the position of the product 200 in the receiving groove 11 along the thickness direction. In this way, when the pallet 100 is shaken or collided during transportation, the limiting portion 302 on the protective cover 30 can provide axial limiting for the product 200, so as to maintain the integrity of the product 200 in the receiving groove 11.

[0056] Exemplarily, the above-mentioned limiting portion 302 can be a step formed at the end of the protective cover 30. When the protective cover 30 is installed in the first cavity 101, the step can abut against a part of the surface of the product 200 to limit the position of the product 200. Of course, in other embodiments, the limiting portion 302 can also be a protrusion protruding from the end of the protective cover 30, and the protrusion abuts against the product 200, which can also play a role in limiting the position of the product 200.

[0057] To facilitate the installation of the protective cover 30, optionally, the outer peripheral surface of the protective cover 30 can be set as an inclined surface so that the outer diameter of the protective cover 30 gradually decreases from top to bottom, so that the protective cover 30 can be better aligned in the first cavity 101, thereby making the installation process of the protective cover 30 smoother.

[0058] The present application also discloses a tray 100 assembly, which includes a plurality of trays 100 as described above, and the plurality of trays 100 are stacked in sequence along the thickness direction. The tray 100 has a first surface 10a and a second surface 10b, so that the second surface 10b of one tray 100 is stacked in abutment with the second surface 10b of another tray 100. In summary, if the first tray 100 and the second tray 100 from top to bottom are used as an example for explanation, the enclosure 20 of the second tray 100 is entirely accommodated in the groove 12 of the first tray 100, specifically, the plurality of second protrusions 102 of the first tray 100 are respectively embedded in the plurality of notches 202 of the second tray 100, and at this time, the protective cover 30 installed in the first cavity 101 of the second tray 100 is accommodated in the first cavity 101 of the first tray 100, so that the first tray 100 and the second tray 100 are stacked, and by analogy, more trays 100 can be stacked.

[0059] The pallet and pallet assembly disclosed in the embodiments of the present application are introduced in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the pallet and pallet assembly of the present application and its core idea. At the same time, for those skilled in the art, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
