Description

Technical Field

[0001] The present invention relates to a buffer member, and more particularly to a buffer member for packaging products. Background Art

[0002] In order to protect products during transportation, current manufacturers will set buffers outside the products and fix the positions of the products by means of the buffers to avoid damage to the products caused by accidental collisions or shaking during transportation. In order to provide good protection, the buffers need to correspond to the size differences between the products and the internal volumes of the shipping cartons. Different buffers need to be designed for products of different sizes, which will increase the manufacturing cost and the cost of controlling the buffers.

[0003] The "Background Art" paragraph is only used to help understand the content of the present invention. Therefore, the content disclosed in the "Background Art" paragraph may include some prior arts that are not known to those skilled in the art. The content disclosed in the "Background Art" paragraph does not represent the problems to be solved by the content or one or more embodiments of the present invention, nor does it represent the prior art known or recognized by those skilled in the art before the filing of the present invention application. Summary of the Invention

[0004] The present invention provides a buffer member that can provide buffering for objects of different sizes.

[0005] To achieve the above advantages, a buffer member of the present invention is used for assembling an object. The buffer member includes a body and a first folding piece. The body includes a first component and a second component. The first component has a first receiving groove, and the second component has a second receiving groove. The first component is connected to the second component, and the first component is used for rotating relative to the second component. The first receiving groove and the second receiving groove form a first accommodating groove when the body is in the unfolded state, and form a second accommodating groove when in the folded state. The first accommodating groove is used for assembling on the side of the object, and the second accommodating groove is used for assembling at the corner of the object. The first folding piece is connected to the first component, and the first folding piece is used for rotating relative to the first component so that the first folding piece switches between a first state and a second state. The first state corresponds to the first folding piece being disposed outside the first receiving groove, and the second state corresponds to the first folding piece being disposed inside the first receiving groove.

[0006] In summary, the buffer member of the embodiment of the present invention has a receiving groove for contacting the target object (which can be the first receiving groove or the second receiving groove according to the state of the main body), and has a first folding piece that can change the size of the receiving groove. Therefore, it can be used corresponding to various target objects of different sizes. In addition, in some embodiments, the buffer member is further provided with a receiving groove (the third receiving groove) outside the receiving groove and corresponding to the size of the first folding piece. Therefore, when the first folding piece is not disposed in the receiving groove but outside the receiving groove, the first folding piece can be received in the receiving groove, so that the contour of the outer surface of the buffer member will not be affected.

[0007] To make the above and other objects, features, and advantages of the present invention more obvious and understandable, specific embodiments are hereinafter given, and in conjunction with the accompanying drawings, they are described in detail as follows. BRIEF DESCRIPTION OF THE DRAWINGS

[0072] The foregoing and other technical contents, features, and effects of the present invention will be clearly presented in the following detailed description of a preferred embodiment with reference to the accompanying drawings. The directional terms mentioned in the following embodiments, such as up, down, left, right, front, or rear, etc., are only with reference to the directions in the drawings. Therefore, the directional terms used are for illustration and not for limiting the present invention.

[0073] Figure 1 A three-dimensional schematic diagram of a buffer member according to an embodiment of the present invention. Figure 2 is Figure 1 A three-dimensional schematic diagram of the buffer member in the buffer member from another angle. Figure 3 is Figure 1 A rear three-dimensional schematic diagram of a form of the buffer member in the deployed state in.

[0074] As Figure 1 and Figure 2 shown, the buffer member 100 is used for being assembled to the target object 101 (see Figure 5 ). The buffer member 100 includes a main body 1 and a first folding piece 21. The main body 1 includes a first component 11 and a second component 12. The first component 11 has a first receiving groove 111, the second component 12 has a second receiving groove 121, the first component 11 is connected to the second component 12, and the first component 11 is used for rotating relative to the second component 12. As Figure 1 and Figure 3 shown, the first receiving groove 111 and the second receiving groove 121 form a first accommodating groove G1 in the main body 1 in the deployed state S11 (see Figure 3 ), and form a second accommodating groove G2 in the folded state S12 (see Figure 8 or Figure 9 ). The first accommodating groove G1 is used for being assembled to the side of the target object 101 (see Figure 8 ), and the second accommodating groove G2 is used for being assembled to the corner of the target object 101 (see Figure 9 ). Returning to Figure 5 , the first folding piece 21 is respectively connected to the first component 11 and the second component 12. The first folding piece 21 is used for rotating relative to the first component 11 (the second component 12) so that the first folding piece 21 switches between a first state S211 and a second state S212 (see Figure 10 ). The first state S211 corresponds to the first folding piece 21 being disposed outside the first receiving groove 111 (the second receiving groove 121), and the second state S212 corresponds to the first folding piece 21 being disposed inside the first receiving groove 111 (the second receiving groove 121). Figure 1 , the first folding piece 21 is respectively connected to the first component 11 and the second component 12. The first folding piece 21 is used for rotating relative to the first component 11 (the second component 12) so that the first folding piece 21 switches between a first state S211 and a second state S212 (see the comparison between Figure 3 and Figure 6 , or the comparison between Figure 8 and Figure 9 ). The first state S211 corresponds to the first folding piece 21 being disposed outside the first receiving groove 111 (the second receiving groove 121), and the second state S212 corresponds to the first folding piece 21 being disposed inside the first receiving groove 111 (the second receiving groove 121).

[0075] In this embodiment, the target object 101 is, for example, a projector, a computer, a television, general household appliances, or other suitable electronic products. As Figure 1 shown, in this embodiment, the buffer member 100 may further include a second folding piece 22, and the second folding piece 22 is connected to the first member 11. In this embodiment, the main body 1, the first folding piece 21, and the second folding piece 22 are, for example, made of the same material, and the material includes, for example, paper, plastic, etc. The first folding piece 21 and the second folding piece 22 and the main body 1 may be thin pieces made in an integrally formed manner.

[0076] As Figure 1 and Figure 3 shown, in this embodiment, when the main body 1 is in the unfolded state S11, it is, for example, an elongated body jointly constituted by the first member 11 and the second member 12. The dimensions of the first member 11 and the second member 12 in the X direction (height direction) are, for example, the same, the dimensions of the first member 11 and the second member 12 in the Z direction (thickness direction) are, for example, also the same, and the first member 11 and the second member 12 are connected to each other along the Y direction ( Figure 1 the major axis direction of the main body 1 in the figure) perpendicular to the X direction and the Z direction.

[0077] On a reference plane parallel to the X direction and the Y direction, the shapes of the first member 11 and the second member 12 are respectively substantially trapezoidal, and one corner of the first member 11 and the second member 12 is connected to each other. When the main body 1 is in the unfolded state S11, the first member 11 and the second member 12 are mirror-symmetrical with the connection point of the first member 11 and the second member 12 as the axis of symmetry, and the above axis of symmetry is, for example, parallel to the Z direction.

[0078] As Figure 1 and Figure 2 shown, the first member 11, for example, presents a trapezoidal body and has a first outer wall surface 11a, a second outer wall surface 11b, a first inclined surface 11c, a first top surface 11d, and two opposite first outer end faces 11e ( Figure 1 only one of the first outer end faces 11e is drawn in the figure). The first outer wall surface 11a and the first top surface 11d are, for example, parallel to each other in the X direction, and the first outer wall surface 11a can be used to contact the inner wall surface (not shown in the figure) of the outer packaging (such as a shipping carton, not shown in the figure) of the target object 101.

[0079] The second outer wall surface 11b and the first inclined surface 11c are connected between the first outer wall surface 11a and the first top surface 11d, and the second outer wall surface 11b faces the Y direction and is, for example, vertically adjacent to the first outer wall surface 11a. In the X direction, the first inclined surface 11c is formed between the first outer wall surface 11a and the first top surface 11d. The first inclined surface 11c is, for example, inclined with respect to the first outer wall surface 11a and the first top surface 11d, and is also inclined with respect to the second outer wall surface 11b.

[0080] The two first outer end faces 11e are parallel to each other in the Z direction, for example, and each is connected to the first outer wall surface 11a, the second outer wall surface 11b, the first inclined surface 11c, and the first top surface 11d. The first outer end face 11e is used to contact the inner wall surface (not shown in the figure) of the outer packaging (such as a shipping carton, not shown in the figure) of the target object 101, for example.

[0081] In this embodiment, the first component 11 has a first receiving groove 111 formed by being recessed in the negative X direction. Specifically, the first receiving groove 111 is a groove, and its opening is formed not only on the first top surface 11d but also partially on the Figure 1 second outer wall surface 11b and the first inclined surface 11c in the middle Y direction. The first receiving groove 111 has a first bottom surface 111a, a first inner wall surface 111b, and a third inner wall surface 111c. The first bottom surface 111a is connected between the first inner wall surface 111b and the third inner wall surface 111c and is parallel to the first outer wall surface 11a and the first top surface 11d, for example. The first inner wall surface 111b and the third inner wall surface 111c face each other and are parallel to the first outer end face 11e in the Z direction, for example.

[0082] As Figure 1 shown, correspondingly, the second component 12 is in the shape of a frustum of a pyramid, for example, and has a third outer wall surface 12a, a fourth outer wall surface 12b, a second inclined surface 12c, a second top surface 12d, and two opposite second outer end faces 12e ( Figure 1 only one of the second outer end faces 12e is drawn in the figure).

[0083] The third outer wall surface 12a and the second top surface 12d are parallel to each other in the X direction, for example, and the third outer wall surface 12a is also used to contact the inner wall surface (not shown in the figure) of the outer packaging (such as a shipping carton, not shown in the figure) of the target object 101. The fourth outer wall surface 12b and the second inclined surface 12c are connected between the third outer wall surface 12a and the second top surface 12d.

[0084] As Figure 2 shown, the fourth outer wall surface 12b faces the negative Y direction and is vertically adjacent to the third outer wall surface 12a. In the X direction, the second inclined surface 12c is formed between the third outer wall surface 12a and the second top surface 12d. The second inclined surface 12c is inclined to the third outer wall surface 12a and the second top surface 12d, and is also inclined to the fourth outer wall surface 12b, for example. The two second outer end faces 12e are parallel to each other in the Z direction, for example, and each is connected to the third outer wall surface 12a, the fourth outer wall surface 12b, the second inclined surface 12c, and the second top surface 12d.

[0085] By Figure 1It can be seen that the first component 11 is connected to the corner between the third outer wall surface 12a and the second inclined surface 12c of the second component 12 at the corner between the first outer wall surface 11a and the first inclined surface 11c. When the main body 1 changes from the unfolded state S11 to the folded state S12 (see Figure 10 ), the first inclined surface 11c and the second inclined surface 12c approach each other, and when the main body 1 is in the folded state S12, the first inclined surface 11c and the second inclined surface 12c are adjacent to each other.

[0086] In this embodiment, the second component 12 is recessed along the negative X direction to form a second receiving groove 121. Specifically, the second receiving groove 121 is also a groove, and its opening is formed not only on the second top surface 12d but also along Figure 1 in the Y direction, and partially formed on the fourth outer wall surface 12b and the second inclined surface 12c. The second receiving groove 121 has a second bottom surface 121a, a second inner wall surface 121b, and a fourth inner wall surface 121c. The second bottom surface 121a is located between the second inner wall surface 121b and the fourth inner wall surface 121c, and is, for example, parallel to the third outer wall surface 12a and the second top surface 12d. The second inner wall surface 121b and the fourth inner wall surface 121c face each other and are, for example, both parallel to the second outer end surface 12e.

[0087] As Figure 3 and Figure 4 shown, when the main body 1 is in the unfolded state S11, the first receiving groove 111 and the second receiving groove 121 together form a first accommodating groove G1 in a groove shape. The first accommodating groove G1 penetrates both ends of the main body 1 along the Y direction, and the opening of the first accommodating groove G1 faces the X direction. As Figure 4 shown, the first accommodating groove G1 has a first groove wall surface G1a, a first groove bottom surface G1b adjacent to the first groove wall surface G1a, and a third groove wall surface G1c opposite to the first groove wall surface G1a and adjacent to the first groove bottom surface G1b. The first groove bottom surface G1b is jointly formed by the first bottom surface 111a of the first receiving groove 111 and the second bottom surface 121a of the second receiving groove 121, and the first bottom surface 111a is parallel to the second bottom surface 121a. The first groove wall surface G1a is jointly formed by the first inner wall surface 111b of the first receiving groove 111 and the second inner wall surface 121b of the second receiving groove 121, and the first inner wall surface 111b is parallel to the second inner wall surface 121b. The third groove wall surface G1c is jointly formed by the third inner wall surface 111c of the first receiving groove 111 and the fourth inner wall surface 121c of the second receiving groove 121, and the third inner wall surface 111c is parallel to the fourth inner wall surface 121c.

[0088] As Figure 5As shown, during use, the first receiving groove G1 connects to the edge of one side of the target object 101 and receives at least a part of the target object 101. In the orthographic projection parallel to any surface of the target object 101, the length L of the main body 1 of the buffer member 100 is, for example, greater than 1 / 3 of the length of the target object 101. For example, two or four buffer members 100 can be installed on the edges of different sides of the target object 101.

[0089] Please refer to Figure 1 、 Figure 8 、 Figure 9 and Figure 10 As shown, when the main body 1 is in the folded state S12, the first receiving groove 111 and the second receiving groove 121 (see Figure 1 ) together form a second receiving groove G2 presenting a bowl shape or a V shape. The opening of the second receiving groove G2 is partially open along the direction D1 and partially open towards the direction D2.

[0090] As Figure 8 shown, the second receiving groove G2 includes a second groove wall surface G2a, a fourth groove wall surface G2d, a second groove bottom surface G2b, and a abutting surface G2c. The second groove wall surface G2a and the fourth groove wall surface G2d are opposite to each other. The second groove wall surface G2a is jointly formed by a first inner wall surface 111b and a second inner wall surface 121b (reference can be made to Figure 4 ). The fourth groove wall surface G2d is jointly formed by a third inner wall surface 111c and a fourth inner wall surface 121c (see Figure 1 ). The second groove bottom surface G2b is adjacent to the abutting surface G2c, and both the second groove bottom surface G2b and the abutting surface G2c are located between the second groove wall surface G2a and the fourth groove wall surface G2d. The second groove bottom surface G2b is formed by a first bottom surface 111a (see Figure 1 ) and faces the X direction. The abutting surface G2c is formed by a second bottom surface 121a (see Figure 1 ) and faces the Y direction. The first bottom surface 111a and the second bottom surface 121a are, for example, perpendicular to each other.

[0091] As Figure 10 shown, during use, the second receiving groove G2 connects to a corner of the target object 101 and receives a part of the target object 101. For example, four buffer members 100 can be used and installed at the four corners of the target object 101, and each buffer member 100 contacts five respective adjacent sides of the target object 101. In an embodiment, the buffer members 100 in the unfolded state S11 and the folded state S12 can be used in combination. The buffer members 100 in the folded state S12 are used to fix the corners of the target object 101, and the buffer members 100 in the unfolded state S11 are used to fix the sides of the target object 101, so as to avoid insufficient buffering of the target object 101 with a longer model.

[0092] The shapes, positions, and the length relationships, angles, or designs or descriptions regarding directions between the walls of the above-mentioned body 1, first component 11, second component 12, first receiving groove G1, and second receiving groove G2 can be changed according to the shape of the outer packaging or the target object 101, or due to changes in the viewing angle.

[0093] In one embodiment, as Figure 11 shown, the first component 11' and the second component 12' of the buffer member 100' are, for example, Figure 1 parts of the buffer member 100. Specifically, the shape of the buffer member 100' is, for example, Figure 1 obtained by cutting along the X direction and the Y direction in. Multiple buffer members 100' can be used to be assembled to the eight corners of the target object 101, and each buffer member 100' contacts three adjacent sides of the target object 101 respectively. Figure 11 The buffer member 100' of Figure 10 contacts three faces of the target object 101, and the buffer member 100 of Figure 4 and Figure 11 contacts four faces of the target object 101. Please refer to Figure 11 and

[0094] In the embodiment of Figure 1 shown, the buffer member 100 in this embodiment includes two first folding pieces 21. The two first folding pieces 21 are respectively connected to the first component 11 and the second component 12. In the following description, since the first component 11 and the second component 12 are symmetric in shape with each other in this embodiment, only the relevant design of the first folding piece 21 on the first component 11 will be described below.

[0095] As Figure 1As shown, the first folding piece 21 is connected to the connection part between the second outer wall surface 11b and the first outer wall surface 11a of the first component 11. The first folding piece 21 includes a connecting part 212 and a thickening part 211 that are connected to each other. The thickening part 211 is located at one end of the first folding piece 21. The connecting part 212 is connected between the first component 11 and the thickening part 211, and the connecting part 212 is used for rotating relative to the first component 11. As Figure 6 shown, when the first folding piece 21 is in the second state S212, the thickening part 211 is disposed inside the first receiving groove 111 to change the size of the first receiving groove 111 and the first accommodating groove G1 in the X direction. There is no particular limitation on the specific size of the change in the size of the first accommodating groove G1 caused by the thickening part 211. In one embodiment, the size of the thickening part 211 can be, for example, corresponding to the thickness of the inner packaging (such as a bag body) of the target object 101. As Figure 5 and Figure 7 shown, if the target object 101' does not have a bag body, the thickening part 211 is disposed inside the first receiving groove 111. If the target object 101 has a bag body, the thickening part 211 is disposed outside the first receiving groove 111. Thus, by changing the state of the first folding piece 21, the buffer 100 can correspond to target objects in different states.

[0096] As Figure 2 shown, in this embodiment, the first component 11 and the second component 12 each have a third receiving groove 13. The third receiving groove 13 is provided on the first outer wall surface 11a. The opening direction of the third receiving groove 13 is opposite to the opening direction of the first receiving groove 111 and faces the negative X direction. As Figure 1 、 Figure 2 and Figure 3 shown, the dimensions of the third receiving groove 13 in the X direction and the Y direction are, for example, corresponding to the dimensions of the first folding piece 21, and the depth of the third receiving groove 13 is, for example, greater than or equal to the thickness of the first folding piece 21, so that the first folding piece 21 can be received in the third receiving groove 13 in the first state S211 and will not protrude from the first outer wall surface 11a.

[0097] As Figure 1 、 Figure 3 and Figure 6 shown, in this embodiment, a convex block 213 is provided on the thickening part 211. The thickening part 211 has a thickness different from that of the connecting part 212 by means of the convex block 213. The position of the convex block 213 is, for example, on the side of the thickening part 211 away from the first bottom surface 111a when the first folding piece 21 is in the second state S212.

[0098] As Figure 1 、 Figure 2As shown, the bump 213 is constituted by, for example, a part of the housing protruding from the thickened portion 211. The bump 213 can be a solid structure or a hollow structure and can be integrally formed with other parts on the thickened portion 211. In other embodiments, the bump 213 can also be constituted by other sheets attached to the first folding piece 21.

[0099] In this embodiment, on the first bottom surface 111a of the first receiving groove 111, a groove 16 is recessed in the direction (negative X direction) toward the first outer wall surface 11a. The size of the groove 16 corresponds to the size of the thickened portion 211, for example, and the depth of the groove 16 corresponds to the thickness of the connecting portion 212, or the thickness obtained by subtracting the thickness of the bump 213 from the thickness of the thickened portion 211. In other words, since part of the thickened portion 211 is received in the groove 16, in this embodiment, the first folding piece 21 mainly affects the position of the first groove bottom surface G1b (or the second groove bottom surface G2b) by the thickness of the bump 213, and one surface of the bump 213 becomes a part of the first groove bottom surface G1b (or the second groove bottom surface G2b), so that the size of the first receiving groove G1 (or the second receiving groove G2) can be reduced. In some embodiments, the first receiving groove 111 may not be provided with the groove 16, or, in some embodiments, the thickened portion 211 may not be provided with the bump 213, and the size of the first receiving groove G1 (or the second receiving groove G2) can be directly changed by the thickness of the thickened portion 211 itself.

[0100] As Figure 2 shown, in this embodiment, a engaging groove 14 can be provided, for example, inside (on the inner side) of the third receiving groove 13. The opening direction of the engaging groove 14 is the same as that of the third receiving groove 13, for example. The size of the engaging groove 14 corresponds to the size of the bump 213 on the first folding piece 21, for example. The engaging groove 14 is used to receive and engage the bump 213 when the first folding piece 21 is received inside the third receiving groove 13. The number and shape of the engaging grooves 14 can correspond to the number and shape of the bumps 213 and can be changed according to the change of the bumps 213. In addition to receiving the bump 213, the engaging groove 14 can also fix the position of the first folding piece 21 by engaging the bump 213, so that when the buffer 100 and the target 101 enter the outer package (such as a shipping carton), the first folding piece 21 will not swing randomly and affect the packaging operation.

[0101] As Figure 1 shown, in this embodiment, the first component 11 and the second component 12 respectively further have a fourth receiving groove 15, for example. The fourth receiving groove 15 is located on the second outer wall surface 11b, for example, and communicates with the groove 16 on the first bottom surface 111a of the first receiving groove 111. The fourth receiving groove 15 is located between the third receiving groove 13 and the first receiving groove 111. The size of the fourth receiving groove 15 corresponds to the size of the connecting portion 212 of the first folding piece 21, for example. As Figure 6 or asFigure 10 As shown, when the first folding piece 21 is in the second state S212, the fourth storage groove 15 is used to store the connecting portion 212 of the first folding piece 21, and the connecting portion 212 does not protrude from the surface of the second outer wall surface 11b.

[0102] It can be understood from the above figures and descriptions that in this embodiment, the first folding piece 21 can be switched between the first state S211 and the second state S212, and the main body 1 can be switched between the unfolded state S11 and the folded state S12. The buffer member 100 can affect the size of the first accommodation groove G1 in the X direction by whether the first folding piece 21 enters the first storage groove 111 (and the second storage groove 121), so that the buffer member 100 can correspond to two different states / sizes of the target object in the unfolded state S11 when using the same outer packaging (such as a shipping carton). For example, Figure 5 the target object 101 is a projector with a bag body, Figure 7 the target object 101' is a projector without a bag body and only has the device itself, and the contour of the target object 101' is slightly smaller than that of the target object 101. Figure 5 the first folding piece 21 of the buffer member 100 is located outside the first storage groove 111 (see Figure 3 ). Figure 7 the first folding piece 21 of the buffer member 100 is located inside the first storage groove 111 (see Figure 6 ). When the main body 1 is in the folded state S12, the first folding piece 21 on the second component 12 can further affect the size of the second accommodation groove G2 in the Y direction.

[0103] In this embodiment, the first folding piece 21 is connected between the third storage groove 13 and the fourth storage groove 15. When the first folding piece 21 enters the groove 16, the connecting portion 212 is stored in the fourth storage groove 15, and a part of the thickening portion 211 enters the groove 16. When the first folding piece 21 enters the third storage groove 13, the entire first folding piece 21 will enter the third storage groove 13. In other embodiments, the sizes of the third storage groove 13, the groove 16, and the length of the connecting portion 221 can be modified correspondingly according to actual usage requirements.

[0104] In this embodiment, since the main body 1 is provided with a third storage groove 13 and a fourth storage groove 15 corresponding to the thickness of the first folding piece 21, no matter whether the first folding piece 21 is in the first state S211 or the second state S212, neither of them will protrude from the first outer wall surface 11a, the second outer wall surface 11b, the third outer wall surface 12a, and the fourth outer wall surface 12b. This enables the same buffer member 100 to provide a buffering effect between various objects 101 of different sizes and the outer packaging when using the same outer packaging. Also, it should be understood from the foregoing description that in an embodiment where the portion of the first folding piece 21 other than the bump 213 is only a thin sheet, the fourth storage groove 15 and the groove 16 may not be provided.

[0105] In one embodiment, the buffer member 100 may be provided with a plurality of first folding pieces 21 (and related corresponding storage grooves), and the thicknesses of the thickening portions 211 of these first folding pieces 21 may be different. In other words, different thicknesses of the first folding pieces 21 can be selected according to different objects 101. Additionally, when the first folding piece 21 is in the second state S212, as Figure 6 shown, the shape of the bump 213 makes the bottom surface G1b of the first groove have an uneven surface, thus enabling the buffer member 100 to better conform to the surface of the object 101.

[0106] As Figure 1 shown, the buffer member 100 of this embodiment further includes two second folding pieces 22, but the number is not limited to this. The two second folding pieces 22 are respectively connected to the first member 11 and the second member 12. In the following description, since the first member 11 and the second member 12 are symmetric to each other, only the relevant design of the second folding piece 22 on the first member 11 will be described below.

[0107] As Figure 1 shown, the second folding piece 22 is connected to the second outer wall surface 11b, located at one side edge of the first storage groove 111, and is also used to rotate relative to the first member 11, enabling the second folding piece 22 to switch between the third state S221 and the fourth state S222. As Figures 3 to 5 or as Figure 8 shown, the third state S221 is the state where the second folding piece 22 is disposed outside the first storage groove 111. As Figures 6 to 7 or Figure 9 shown, the fourth state S222 is the state where the second folding piece 22 is disposed inside the first storage groove 111.

[0108] Similar to the description of the aforementioned first folding piece 21, when the second folding piece 22 is in the fourth state S222 located inside the storage groove 111, one side of the second folding piece 22 will become a part of the first groove wall surface G1a (or the second groove wall surface G2a), and the size of the first accommodation groove G1 (or the second accommodation groove G2) can be reduced. As Figure 5 and Figure 7 shown, if the target object 101' does not have a bag body, the second folding piece 22 is arranged inside the first storage groove 111. If the target object 101 has a bag body, the second folding piece 22 is arranged outside the first storage groove 111.

[0109] In this embodiment, for example, a fifth storage groove 17 recessed toward the center of the main body 1 is provided on the second outer wall surface 11b. The size of the fifth storage groove 17 is, for example, larger than the size of the second folding piece 22, and the depth of the fifth storage groove 17 is, for example, equal to the thickness of the second folding piece 22. Thus, when the second folding piece 22 is in the third state S221, the second folding piece 22 does not protrude from the second outer wall surface 11b.

[0110] As can be observed from the above figures, the first folding piece 21 and the second folding piece 22 on the first component 11 (and the second component 12) are respectively used to contact different wall surfaces of the first storage groove 111 (and the second storage groove 112). In other words, both the first folding piece 21 and the second folding piece 22 can affect the size of the first accommodation groove G1 (or the second accommodation groove G2). Due to the different arrangement directions of the first folding piece 21 and the second folding piece 22, the first folding piece 21 and the second folding piece 22 affect the size of the first accommodation groove G1 (or the second accommodation groove G2) in different directions. That is, by increasing the folding pieces arranged in different directions, the buffer 100 can adapt to products with different appearances. Taking the structure of this embodiment as an example, when the main body 1 is in the unfolded state S11, by changing the states of the first folding piece 21 (the first state S211 and the second state S212) and the second folding piece 22 (the third state S221 and the fourth state S222), the main body 1 can correspond to the sizes of four different target objects 101 without changing the size and appearance of the outer packaging. Therefore, if the state of the main body 1 (the unfolded state S11 and the folded state S12) is further changed, the number of variations of the buffer 100 can be further increased. If the types or numbers of the folding pieces are further increased (for example, other folding pieces that can affect the position of the first groove bottom surface G1b are provided), or the states or designs of the first folding piece 21 and the second folding piece 22 on the first component 11 and the second component 12 are respectively adjusted according to requirements, the corresponding variations will become more.

[0111] As can be seen from the above description, the buffer member of the embodiment of the present invention has a receiving groove for contacting the target object (which can be the first receiving groove or the second receiving groove according to the state of the body), and has a first folding piece that can change the size of the receiving groove, so it can be used corresponding to various target objects of different sizes. In addition, in some embodiments, the buffer member is further provided with a receiving groove (the third receiving groove) outside the receiving groove and corresponding to the size of the first folding piece. Therefore, when the first folding piece is not disposed in the receiving groove but outside the receiving groove, the first folding piece can be received in the receiving groove, so that the contour of the outer surface of the buffer member is not affected.

[0112] The above are only the preferred embodiments of the present invention, and the scope of implementation of the present invention cannot be limited thereby. That is, all simple equivalent changes and modifications made in accordance with the claims of the present invention and the content of the specification still fall within the scope covered by the patent of the present invention.
