[0002] As a device integrated with functions such as a gateway, a smart socket, and an infrared remote control, an air conditioner companion enables users to directly remotely control an air conditioner through a smart speaker or a mobile phone, transforming a traditional air conditioner into a smart air conditioner. In related technologies, some manufacturers design the appearance of the air conditioner companion as a spherical structure to provide a more gentle shape and bring more choices to users.
[0003] However, in order to prevent products with a circular cross-section from shaking during transportation, a lining structure is used to tightly wrap around the spherical product, often resulting in over-tight packaging and making it difficult to take out products with such a type of structure. Summary of the Utility Model
[0004] The utility model provides a buffer lining and a buffer packaging, which are used to reduce the difficulty of taking out a product when firmly fixing a product with a circular cross-section.
[0005] In a first aspect, the utility model provides a buffer lining, including: a lining main body, which is provided with a receiving hole having an opening, the receiving hole being used to receive a product, and the inner contour dimension of the receiving hole in a first direction being greater than the outer contour dimension of the product, and the inner contour dimension of the receiving hole in a second direction being equal to or less than the outer contour dimension of the product, so that when the product is placed in the receiving hole, the inner wall of the receiving hole can form a taking cavity located outside the product with the product it receives, the taking cavity being connected to the opening and being able to allow a finger to be inserted; and a limiting protrusion, which is arranged on the inner wall of the receiving hole and is used to contact the product to limit the product in the receiving hole.
[0006] In an embodiment, the cross-section of the receiving hole at the opening is square, and the hole width of the receiving hole is equal to or less than the maximum outer diameter of the product, so as to correspondingly form four such taking cavities at the four corners of the receiving hole.
[0007] In an embodiment, the distance by which the limiting protrusion protrudes from the hole wall of the receiving hole is less than or equal to 1 mm.
[0008] In an embodiment, the hole wall of the receiving hole includes a first area and a second area, wherein the first area can contact the product, the second area can form the taking cavity with the product, and the limiting protrusion is arranged at the first area.
[0009] In one embodiment, the receiving hole includes a first hole section and a second hole section that communicate with each other, wherein the aperture of the first hole section is larger than that of the second hole section, and the inner lining main body forms a positioning end face at the connection between the first hole section and the second hole section.
[0010] In one embodiment, the second hole section is located at one end of the first hole section away from the opening, and the limiting protrusion is arranged on the first hole section.
[0011] In one embodiment, the inner lining main body is used to be installed in a box body, and the inner lining main body includes a first shell part and a second shell part arranged coaxially. The outer contour size of the first shell part corresponds to the inner contour size of the box body, and the outer contour size of the first shell part is larger than that of the second shell part.
[0012] In one embodiment, a first guiding inclined surface is arranged on one side of the limiting protrusion close to the opening, and the included angle between the first guiding inclined surface and the hole wall of the receiving hole is an obtuse angle.
[0013] In one embodiment, a plurality of the limiting protrusions are arranged on the inner wall of the receiving hole, and the limiting protrusions are arranged at intervals around the axis direction of the receiving hole so that when a product is placed in the receiving hole, the plurality of limiting protrusions contact the product in the receiving hole simultaneously.
[0014] In a second aspect, the present utility model further provides a buffer packaging, which includes: the above-mentioned buffer inner lining, and a box body, and the buffer inner lining is installed in the box body.
[0015] Compared with the prior art, the advantages of the present utility model are that the inner lining main body of the buffer inner lining has a receiving hole. The inner contour size of the receiving hole in the first direction is larger than the outer contour size of the product, the inner contour size of the receiving hole in the second direction is equal to the outer contour size of the product, and limiting protrusions are arranged at the inner wall of the receiving hole.

[0037] The present utility model will be further described below in conjunction with the accompanying drawings.
[0038] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, there is an air conditioner companion product 300, which includes a spherical spherical main body 310, and a connecting plug 320 is arranged at the bottom of the spherical main body 310. During use, the air conditioner companion product 300 can be connected to the circuit by inserting the connecting plug 320 into the corresponding socket or jack. The energized air conditioner companion can communicate with a traditional air conditioner, so that the user can adjust the traditional air conditioner by means of mobile phone control or voice control, which facilitates the user to operate the traditional air conditioner.
[0039] Compared with a product with a flat surface, a spherical-structured product is more likely to roll. If the spherical product is not properly fixed, it will cause the spherical product to roll and be scratched or damaged during transportation.
[0040] In the related art, in order to limit the spherical structure and prevent the spherical product from shaking during transportation, an inner lining structure is used to tightly wrap the spherical structure, resulting in too tight connection between the inner lining structure and the product, making it difficult to take out the product from the inner lining structure.
[0041] In order to firmly fix the spherical equipment main body during transportation and reduce the difficulty of taking out the product from the packaging. The present utility model provides a buffer inner lining 100, see Figures 1 to 4As shown, the buffer lining 100 includes a lining main body 110 and a limit projection 120. The lining main body 110 is provided with a receiving hole 111 having an opening. When packaging a product is required, the product can be placed in the receiving hole 111 from the opening.
[0042] See Figures 5 to 8 As shown, the limit projection 120 is arranged at the inner wall of the receiving hole 111. By contacting the product through the limit projection 120, the movement of the product in the receiving hole 111 is restricted, and the product is firmly fixed in the buffer lining 100, ensuring the safety of the product during transportation.
[0043] The inner contour dimension of the receiving hole 111 in the first direction (such as the diagonal direction in Figure 9 ) is larger than the outer contour dimension of the product. The inner contour dimension of the receiving hole 111 in the second direction (such as the width direction or the length direction in Figure 9 ) is equal to or smaller than the outer contour dimension of the product. By controlling the inner contour dimension of the receiving hole 111, when the product is inserted into the receiving hole, a picking cavity 112 can be formed between the hole wall of the receiving hole 111 and the outer side surface of the product.
[0044] Figure 9 In
[0045] , the inner contour dimension of the receiving hole 111 in the second direction is equal to the outer contour dimension of the product, so that the product can be just placed in the receiving hole 111 and contact the hole wall of the receiving hole 111. In some other implementation manners, the inner contour dimension of the receiving hole 111 in the second direction can also be controlled to be a little smaller (0.2 mm - 1 mm) than the outer contour dimension of the product in the second direction, and the product is clamped by the hole wall of the receiving hole 111.
[0045] As Figure 9 , Figure 10 and Figure 11 shown, when the product is placed in the receiving hole 111, a picking cavity 112 that can be inserted by a finger can be formed between the inner wall of the receiving hole 111 and the outer surface of the product. Among them, the picking cavity 112 is communicated with the opening of the receiving hole 111. When the product needs to be taken out of the receiving hole 111, the product placed in the receiving hole 111 can be contacted by inserting a finger into the picking cavity 112, so as to take out the product from the receiving hole 111.
[0046] Compared with the lining main body 110 that surrounds and closely adheres to the product, the buffer lining 100 of the present application reserves a picking cavity 112 that can be inserted by a finger for taking out the product, so that not only can the product be contacted from the opening, but also the finger can contact the side surface of the product by inserting the finger into the picking cavity 112. Thereby, the force application environment when taking out the product is improved, and the difficulty of taking out the product is reduced.
[0047] See Figure 5 and Figure 9As shown, in some implementations, the cross-section of the receiving hole 111 at the opening is square, and the hole width of the receiving hole 111 is equal to the maximum outer diameter of the product, so as to correspondingly form four picking cavities 112 at the four corners of the receiving hole 111. When placing the spherical body of the product in the receiving hole 111, the maximum outer diameter of the product fits against the hole wall of the receiving hole 111, and four picking cavities 112 are formed at the four corners of the receiving hole 111. When it is necessary to take out the product from the receiving hole 111, four fingers can be correspondingly inserted into the four picking cavities 112 to conveniently take out the product in the receiving hole 111.
[0048] Compared with the irregular receiving hole 111, the mold for the square hole is more mature, and the square mold can be purchased at a low cost, so that the receiving hole 111 with the picking cavity 112 can be formed, reducing the production cost of the buffer lining 100.
[0049] In other implementations, an irregular receiving hole 111 can also be provided on the lining body 110, such as Figure 10 and Figure 11 As shown, the receiving hole 111 can include a round hole and a chamfered hole that extend coaxially and are connected. The two side walls of the chamfered hole are tangent to the hole wall of the round hole, and the two side walls of the two chamfered holes intersect to form a chamfer. When placing the spherical product in this combined hole, the inner wall of the round hole fits against the product, while the side wall of the chamfered hole is spaced from the product, and the side wall of the chamfered hole and the outside of the product enclose a picking cavity 112. Among them, the number of chamfered holes can be one, two, or three. So as to form one, two, or three picking cavities 112 when the product is placed in the receiving hole 111.
[0050] In some implementations, the receiving hole 111 includes two chamfered holes symmetrically arranged along the axis of the round hole. When placing the product in the receiving hole 111, the hole wall of the receiving hole 111 will form two opposite picking cavities 112 with the outer side surface of the product, so that fingers can be inserted from the opposite sides of the product, and the product received in the receiving hole can be clamped by the fingers, reducing the difficulty of taking out the product without affecting the limitation of the product by the limiting protrusion 120.
[0051] It can be understood that Figure 9 and Figure 10 the chamfers of the chamfered holes in are right-angled chamfers. In the actual processing process, the chamfers of the chamfered holes can also be set to acute angles or obtuse angles, as long as the space formed by the chamfered hole and the outer side wall of the product can satisfy the insertion of the fingers.
[0052] Among them, the arrangement of the chamfered holes can be equiangularly spaced, or the chamfered holes can be equally spaced according to the finger spacing distance of the human body, so that the distance between adjacent two chamfered holes is equal to the interval between adjacent fingers, facilitating the insertion of the fingers on the same palm into the adjacent picking cavities 112.
[0053] In some implementations, the distance by which the limiting protrusion 120 protrudes from the hole wall of the receiving hole 111 is less than or equal to 1 mm. By setting the size of the limiting protrusion 120 to be relatively small, the limiting protrusion 120 can be deformed with a relatively small force when installing the product, so that the product can break through the limiting protrusion 120 and be clamped between the limiting protrusions 120. When removing the product, the limiting protrusion 120 can be deformed with a relatively small force, so that the product can break through the limiting protrusion 120, facilitating the removal of the product. Compared with the limiting protrusion 120 with a longer protruding distance, the difficulty for the product to break through the limiting protrusion 120 can be reduced, and the difficulty of installing and removing the product is reduced.
[0054] In some implementations, the limiting protrusion 120 can also be made of an elastic material, avoiding excessive damage to the limiting protrusion 120 or the product when the product breaks through the limiting protrusion 120, and extending the service life of the limiting protrusion 120.
[0055] In some implementations, the hole wall of the receiving hole 111 includes a first region and a second region. Among them, the first region can contact the product, and the second region can enclose an object-taking cavity 112 with the product, and the limiting protrusion 120 is arranged at the first region. By arranging the limiting protrusion 120 at the first region that can fit the product, the limiting protrusion 120 can be made to contact the product, and the limiting of the product can be achieved by using the limiting protrusion 120.
[0056] In some implementations, no limiting protrusion 120 is arranged at the second region, avoiding the limiting protrusion 120 from affecting the insertion of the finger, so that the finger can be more conveniently inserted into the object-taking cavity 112 to take out the product placed in the receiving hole 111.
[0057] See Figure 5 and Figure 9 As shown, when the receiving hole 111 is a square hole, the symmetry plane of the receiving hole 111 includes a first symmetry plane perpendicular to a pair of hole walls and a second symmetry plane perpendicular to the other pair of hole walls. The first region refers to the intersection region of the first symmetry plane and the hole wall perpendicular to it and the intersection region of the second symmetry plane and the hole wall perpendicular to it. The second region refers to the other regions of the hole wall except the first region.
[0058] See Figure 10 and Figure 11 As shown, in some implementations, when the receiving hole 111 has an arc-shaped fitting hole wall that fits the product, the arc-shaped hole wall that fits the product is the first region, and the limiting protrusion 120 can be arranged to extend along the circumference of the arc to improve the limiting of the product.
[0059] In some implementations, the inner lining body 110 and the limiting protrusion 120 are integrally formed. In other implementations, the inner lining body 110 and the limiting protrusion 120 can be set to be detachably connected. For example, a jack structure is provided on the inner lining body 110, and the limiting protrusion 120 is detachably inserted into the jack structure on the inner lining body 110 to achieve the detachable connection between the limiting protrusion 120 and the inner lining body 110.
[0060] Among them, the buffer inner lining 100 can be made by processes such as thermoforming and injection molding, and the material of the buffer inner lining 100 can be selected from one or a mixture of multiple materials among PP, PS, or ABS.
[0061] See Figure 5 and Figure 12 As shown, the receiving hole 111 includes a first hole section 1111 and a second hole section 1112 that are connected and communicate with each other. Among them, the aperture of the first hole section 1111 is larger than that of the second hole section 1112, and the inner lining body 110 forms a positioning end face at the connection of the first hole section 1111 and the second hole section 1112.
[0062] That is to say, the receiving hole 111 is a stepped hole structure. The spherical body is received through the first hole section 1111 with a larger aperture, and the connection plug is received through the second hole section 1112 with a smaller aperture. Through the positioning end face, axial positioning of the spherical body received in the first hole section 1111 can be achieved.
[0063] It can be understood that the aperture of the second hole section 1112 is larger than the outer diameter of the connection plug and smaller than the outer diameter of the spherical body, and the depth of the second hole section 1112 is greater than the length of the connection plug. In some implementations, in order to properly accommodate the British plug, the depth of the second hole section 1112 is 25 mm.
[0064] In some implementations, the second hole section 1112 is located at one end of the first hole section 1111 away from the opening, and the limiting protrusion 120 is provided in the first hole section 1111.
[0065] In some implementations, the distance between the limiting protrusion 120 and the positioning end face is set according to the size of the spherical body. Specifically, the distance between the limiting protrusion 120 and the positioning end face is a first distance, and the distance between the maximum diameter of the spherical body and the bottom positioning face of the spherical body is a second distance. Among them, the first distance is greater than the second distance. When the spherical body is placed in the receiving hole 111, the limiting protrusion 120 is located above the maximum diameter of the spherical body, so as to prevent the spherical protrusion from moving upward through the limiting protrusion 120.
[0066] See Figure 5 and Figure 6As shown, in some implementations, the second hole section 1112 is a blind hole structure, that is, one end of the second hole section 1112 away from the first hole section 1111 is closed. By closing the second hole section 1112, foreign objects in the environment can be prevented from entering the accommodation hole 111 from one end of the second hole section 1112 to contaminate the product.
[0067] See Figure 5 As shown, the cross-section of the second hole section 1112 is also square, and the hole width of the second hole section 1112 is greater than the length of the connection plug in the hole width direction. This can prevent the connection plug from directly contacting the hole wall of the second hole section 1112 and avoid interference between the hole wall of the second hole section 1112 and the connection plug.
[0068] See Figure 6 and Figure 7 As shown, the inner lining main body 110 is used to be installed in the box body 200. The inner lining main body 110 includes a first shell part 113 and a second shell part 114 which are coaxially arranged. The outer contour size of the first shell part 113 corresponds to the inner contour size of the box body 200, and the outer contour size of the first shell part 113 is greater than the outer contour size of the second shell part 114.
[0069] See Figure 6 and Figure 7 As shown, in some implementations, the inner lining main body 110 includes a first shell part 113, a second shell part 114 and a third shell part 115 which are coaxially arranged. Among them, the outer contours of the first shell part and the second shell part and the outer contour size of the third shell part decrease in sequence. Thus, when inserting the buffer inner lining 100 into the box body 200, first the third shell part 115 with the smallest outer contour size is inserted into the box body 200, and then by further moving the buffer inner lining 100, the second shell part 114 and the first shell part 113 can be inserted into the box body 200. Finally, the outer contour of the first shell part 113 fits with the inner side surface of the box body 200 to prevent the buffer inner lining 100 from shaking inside the box body 200. The first hole section 1111 is formed in the combined structure of the first shell part 113 and the second shell part 114, while the second hole section 1112 is formed in the third shell part 115.
[0070] When installing the inner lining main body 110 in the box body 200, the outer contour of the first shell part 113 fits with the inner surface of the box body 200 to prevent the inner lining main body 110 from shaking relative to the box body 200. And the outer contour size of the second shell is smaller than that of the first shell, so that when installing the inner lining main body 110 in the box body 200, there is a gap between the outer contour of the second shell and the inner side wall of the box body 200. Thus, after the first shell positions the inner lining main body 110, the contact area between the inner lining main body 110 and the box body 200 is reduced, the friction between the inner lining main body 110 and the box body 200 is reduced, and thus the difficulty of inserting or removing the inner lining main body 110 from the box body 200 is reduced.
[0071] See Figure 7 and Figure 8 As shown, a first guiding surface 121 is provided on one side of the limiting protrusion 120 close to the opening, and the included angle between the first guiding surface 121 and the hole wall of the receiving hole 111 is an obtuse angle. When the product is inserted into the receiving hole 111 from the opening, the spherical body of the product will first be in contact with the first guiding surface 121 of the limiting protrusion 120, and the included angle between the first guiding surface 121 and the hole wall of the receiving hole 111 is an obtuse angle. The first guiding surface 121 can guide the spherical body of the product to be inserted into the receiving hole 111, reducing the difficulty of the product inserted into the receiving hole 111 to break through the limiting protrusion 120.
[0072] See Figure 8 As shown, a second guiding surface 122 is provided on one side of the limiting protrusion 120 away from the opening, and the included angle between the second guiding surface 122 and the hole wall of the receiving hole 111 is an obtuse angle.
[0073] When the product is taken out of the receiving hole 111, the maximum outer diameter of the spherical body will contact the second guiding surface 122 of the limiting protrusion 120, guiding the spherical body along the second guiding surface 122 to the notch, facilitating the removal of the spherical body.
[0074] In some implementation manners, an anti-slip texture structure can be provided on the outer surface of the limiting protrusion 120 to increase the friction between the limiting protrusion 120 and the spherical body, and avoid the spherical protrusion breaking through the limiting protrusion 120 due to collision during transportation.
[0075] A plurality of limiting protrusions 120 are provided on the inner wall of the receiving hole 111, and the limiting protrusions 120 are arranged at intervals around the axis of the receiving hole 111, so that when the product is placed in the receiving hole 111, the plurality of limiting protrusions 120 are in contact with the product in the receiving hole 111 at the same time.
[0076] That is to say, in this application, the product is limited by a plurality of spaced limiting protrusions 120. Compared with limiting the product by a single limiting protrusion 120, the product can be limited more firmly.
[0077] Specifically, see Figure 5 and Figure 9As shown, in some implementations, two pairs of limiting protrusions 120 are provided on the inner wall of the receiving hole 111. When the product is placed in the receiving hole 111, one pair of limiting protrusions 120 is arranged on the opposite sides of the product to clamp the spherical body, and the other pair of limiting protrusions 120 also clamps on both sides of the spherical body. The clamping directions of the two pairs of limiting protrusions 120 are perpendicular to each other. The limiting of the spherical body in the receiving hole 111 is achieved through the two pairs of limiting protrusions 120, avoiding the shaking of the spherical body relative to the buffer lining 100 during transportation.
[0078] In some implementations, the distance between two relatively arranged limiting protrusions 120 is less than the maximum diameter of the spherical body, so that when the spherical body is limited by the limiting protrusions 120, the limiting protrusions 120 can fit more closely with the spherical body, and the product can be stored in the receiving hole 111 more securely.
[0079] See Figure 1 、 Figure 13 and Figure 14 As shown, in the second aspect, an embodiment of the present invention further provides a buffer package, which includes the above-mentioned buffer lining 100 and a box body 200, and the buffer lining 100 is installed in the box body 200. Due to the adoption of the above-mentioned buffer lining 100, the limiting of the product can be achieved through the limiting protrusions 120 of the buffer lining 100, avoiding the product from shaking out of the receiving hole 111 of the lining main body 110. Moreover, since the inner contour size of the lining main body 110 is larger than the outer contour size of the product, a picking cavity 112 that can be inserted by fingers is formed between the hole wall of the receiving hole 111 and the outer contour of the product, thereby reducing the difficulty of taking out the product from the receiving hole 111.
[0080] See Figure 13 and Figure 14 As shown, the box body 200 of the present application is formed by folding an integrated straight plate. After the box body 200 is unfolded, the occupied space of the box body 200 is greatly reduced, facilitating the transportation of the box body 200. The box body 200 includes a first enclosing board 201, a second enclosing board 202, a third enclosing board 203 and a fourth enclosing board 204 that are connected in sequence. By folding the four enclosing boards into a structure where adjacent board bodies are perpendicular, a frame-like structure can be formed by the four enclosing boards.
[0081] A first locking board 205 is connected to the bottom of the first enclosing board 201; a second locking board 206 is connected to the bottom of the second enclosing board 202; a third locking board 207 is connected to the bottom of the third enclosing board 203; a fourth locking board 208 is connected to the bottom of the fourth enclosing board 204.
[0082] After the bonding plate 213 on the side of the first enclosing plate 201 is bonded to the fourth enclosing plate 204, the first locking plate 205 and the third locking plate 207 are folded upwards, then the second locking plate 206 is folded upwards to cover the outer sides of the first locking plate 205 and the third locking plate 207, and the front end of the second locking plate 206 is inserted into the gap formed by the first locking plate 205 and the third locking plate 207, so that the second locking plate 206 extends to the inner side of the first locking plate 205. After that, the fourth locking plate 208 is inserted into the groove at the front end of the second locking plate 206, and then the front end of the fourth locking plate 208 can extend to the outer side of the first locking plate 205, while the tail of the fourth locking plate 208 is arranged outside the first locking plate 205, forming a locking structure. This prevents the buffer lining 100 and the product 300 placed in the box body 200 from falling off.
