DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0038] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0039] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0040] See also Figure 1-11 As shown, the present invention provides a packaging cushioning component,

[0041] The floor fan comprises a blade cover 1 and a base 2, the base 2 and the blade cover 1 are both disc-shaped, the outer contour diameter of the base 2 is larger than the outer contour diameter of the blade cover 1, and is characterized in that the packaging buffer assembly comprises a buffer body, the buffer body is provided with a blade cover groove 101 for accommodating the blade cover 1 and a base groove 201 for accommodating the base 2, with the spatial orientation of the floor fan in the use state as a reference, the space includes six directions of up and down, left and right, front and back, and the blade cover 1 and the base 2 are both vertically arranged in their respective accommodating grooves;

[0042] The base groove 201 is arranged on one side of the blade cover groove 101 in the horizontal direction, and the buffer body includes an upper top surface and a lower bottom surface. In the projection in the up and down directions, the area where the upper top surface covers the blade cover 1 is the first upper area, and the area where the lower bottom surface covers the blade cover 1 is the first lower area; the first upper area is provided with a first upper material reduction groove 7011, and / or the first lower area is provided with a first lower material reduction groove 7012.

[0043] The spatial directions of “up and down, left and right, front and back” in the present application are defined for the convenience of describing the packaging and cushioning components of the present application, and do not impose specific limitations on the structure of the packaging and cushioning components.

[0044] The "vertical setting" refers to the up-down direction, that is, the disc-mounted fan blade cover and the disc surface of the base face the horizontal direction.

[0045] During transportation, the base 2 and the blade cover 1 are susceptible to vibrations in the up and down directions. The vertical arrangement of the base 2 and the blade cover 1 can reduce the adverse effects of the up and down vibrations on the base 2 and the blade cover 1. Since the outer contour diameter of the base 2 is larger than the outer contour diameter of the blade cover 1, while ensuring that the buffer body has the same vibration reduction effect on the base 2 and the blade cover 1, material reduction grooves are set in the first upper area and the first lower area, which effectively reduces the material used for the buffer body. Since the structural strength of the blade cover 1 itself is less than the structural strength of the base, the first upper area and the first lower area provided with the material reduction grooves can better deform and absorb energy, thereby improving the protection of the blade cover 1.

[0046] Furthermore, the material of the buffer body is EPS (expanded polystyrene).

[0047] Preferably, Figure 3 As shown, the upper top surface is provided with a plurality of the first upper material reducing grooves 7011, and the entity structure between two adjacent first upper material reducing grooves 7011 is a first upper reinforcing rib 801;

[0048] and / or,

[0049] The lower bottom surface is provided with a plurality of the first lower material reducing grooves 7012 , and the solid structure between two adjacent first lower material reducing grooves 7012 is a first lower reinforcing rib 802 .

[0050] Providing multiple first upper material reduction grooves 7011 can further reduce the material usage, weight and cost. The first upper reinforcing rib 801 between two adjacent first upper material reduction grooves 7011 can improve the structural strength of the buffer body and greatly reduce the possibility of the buffer body being broken or deformed during transportation. The first upper reinforcing rib 801 can deform and absorb energy, thereby improving the vibration reduction and energy absorption effect of the buffer body. The first lower reinforcing rib not only has the technical effect of the first upper reinforcing rib 801, but also because the first lower area is located on the lower surface, the first lower reinforcing rib makes the lower surface of the buffer body smoother and more coherent as a whole (no single groove with a larger area will appear), thereby improving the support performance of the buffer body.

[0051] The depths of the plurality of first upper material reducing grooves 7011 may be different, and similarly the depths of the plurality of first lower material reducing grooves 7012 may also be different, under the premise of ensuring structural strength and vibration reduction effect.

[0052] Preferably, Figure 3As shown, the upper top surface has four corners, and the two corners closest to the fan blade cover (1) are the first corner and the second corner; the first upper reinforcing rib (801) includes at least two, one end of the first upper reinforcing rib (801) is connected to the first corner, and the other end of the first upper reinforcing rib (801) is connected to the second corner.

[0053] Each corner structure of the buffer body is most vulnerable to damage. During transportation, the position is low and the upper surface is high, so the upper surface is more susceptible to collision and damage. Since the blade cover groove 101 is set closer to a corner, in order to further improve the protection of the blade cover 1, the two first upper reinforcing ribs 801 are connected to the first corner and the second corner respectively to improve the support effect on the first corner and the second corner, improve the structural strength of the first corner and the second corner, and then improve the protection performance of the blade cover 1.

[0054] Preferably, Fig.10 As shown, the horizontal direction includes the front-back direction and the left-right direction which are perpendicular to each other. The back of the fan cover 1 is provided with a housing 3, and the buffer body is also provided with a housing slot 301 for accommodating the housing 3. Figure 5 and Fig. 9 As shown, the base groove 201 is arranged on the left side or the right side of the housing groove 301 , and in the left-right direction, the projection of the base groove 201 partially overlaps with the projection of the housing groove 301 .

[0055] The fan blade cover 1 includes a front side and a back side, and the front side is the direction of air outlet. A motor for driving the fan blades to rotate is arranged in the housing 3.

[0056] The base groove 201 is arranged on the left or right side of the casing groove 301 , and the projection of the base groove 201 partially overlaps with the projection of the casing groove 301 , thereby reducing the size of the buffer body in the front-to-back direction, which is beneficial to reducing the volume of the buffer body.

[0057] Furthermore, in the left-right direction, the shortest distance between the base slot 201 and the housing slot 301 is approximately 10 mm, that is, the physical thickness between the two slots is approximately 10 mm, thus avoiding damage caused by insufficient buffering between the base 2 and the housing 3 during transportation.

[0058] Preferably, Figure 1-2 As shown, the housing 3 is connected to a support portion 4. Figure 4 and Fig. 9As shown, the buffer body is also provided with a support portion groove 401 for accommodating the support portion 4, the support portion groove 401 and the base groove 201 are arranged on the same side of the casing groove 301, and the base groove 201 is arranged on the rear side of the support portion groove 401, and in the front-to-back direction, the projection area of ​​the blade cover groove 101 is larger than the projection area of ​​the casing cover groove 301, the projection of the base groove 201 partially overlaps with the projection of the blade cover 1, and the projection of the base 2 does not overlap with the projection of the casing 3.

[0059] In the front-to-back direction, the projection area of ​​the casing groove 301 is smaller than the projection area of ​​the blade cover 1. This means that behind the blade cover groove 101, in addition to the casing groove 301, there is a certain area B. The projection of the base groove 201 partially overlaps with the projection of the blade cover 1, and the projection of the base 2 does not overlap with the projection of the casing 3. The support groove 401 and the base groove 201 can make full use of the area B. In this way, the size of the buffer body in the left and right directions is further reduced, which is beneficial to reducing the volume of the buffer body.

[0060] Preferably, Figure 1-2 As shown, the floor fan also includes a connecting rod 5 for connecting the fan blade cover 1 and the base 2. Figure 4 and Figure 5 As shown, the buffer body is further provided with a connecting rod groove 501 for accommodating the connecting rod 5 , and the connecting rod groove 501 is arranged between the fan blade cover groove 101 and the base groove 201 .

[0061] Since the support part 4 is connected to the casing 3, the support part groove 401 is also connected to the casing groove 301. In the front-to-back direction, the size of the casing groove 301 is larger than the size of the base groove. There is also space that can be utilized between the fan blade cover groove 101 and the base groove 201. By setting the connecting rod groove 501 in the space, the buffer body can be further utilized, which is beneficial to reducing the size of the buffer body.

[0062] Specifically, Fig.11 As shown, the disk surface of the base faces the front-to-back direction, the front side of the blade cover 1 faces the front, the distance between the base groove and the blade groove in the front-to-back direction is a, the distance between the casing groove 301 and the upper surface of the buffer body is b, and the maximum cross-sectional dimensions of the connecting rod 5 are both smaller than a and smaller than b. In this way, the connecting rod groove 501 can be set between the blade cover groove 101 and the base groove 201.

[0063] Preferably, Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the connecting rod groove 501 is arranged on the upper top surface of the buffer body.

[0064] Since the connecting rod 5 is a fixed hard rod, the connecting rod 5 has a small demand for vibration reduction, and the connecting rod groove 501 is set on the upper top surface of the buffer body. The buffer body can not only cover and reduce vibration of the connecting rod 5 to a certain extent, but also facilitate the taking and placing of the connecting rod 5. On the upper top surface, the material taking groove is set between the fan blade cover groove 101 and the base groove 201, which will reduce the structural strength of the upper top surface, especially the poor pressure bearing. The connecting rod groove 501 is set on the upper top surface. When the connecting rod 5 is set in the connecting rod groove 501, the overall structural strength of the upper top surface can be improved.

[0065] Preferably, Figure 1-2 As shown, the support portion 4 includes a support rod 402 and a rotating member 403 connected between the support rod 402 and the housing 3, and the first end of the support rod 402 is rotatably connected to the rotating member 403, as shown in FIG. Figure 3 , Figure 4 and Figure 6 As shown, the first end of the support rod 402 is located in the support portion groove 401 , and the buffer body is provided with a second material reduction groove 702 , and the second material reduction groove 702 surrounds the second end of the support rod 402 .

[0066] The rotating member 403 needs better protection and vibration reduction. The rotating member 403 is covered as a whole. The support rod 402 itself only plays a connecting role and is made of a harder material. When the first end of the support rod 402 is connected to the rotating member 403 and protected, the second end of the support rod 402 can be suspended, that is, the second end of the support rod 402 is hollowed out to form a second material reduction groove 702, and the second end of the support tube is not covered by any physical structure. In this way, while ensuring the safety of the support rod 402, the consumption of vibration reduction materials is further reduced, and the weight of the buffer body is reduced.

[0067] Preferably, Figure 3 As shown, the second material reduction groove 702 includes a first notch 7021 and a second notch 7022 , the first notch 7021 faces the front side, and the direction of the second notch 7022 is consistent with the direction of the second end of the support rod 402 .

[0068] The second material reduction groove 702 is provided with a first notch 7021 and a second notch 7022, so that the volume of the second material reduction groove 702 is larger, and the consumption of the vibration reduction material is reduced as much as possible, which is conducive to reducing costs. The first notch 7021 and the second notch 7022 can be used for transportation, which improves the convenience of transportation of the buffer body. The first material reduction port and the second material reduction port can be connected to form a notch.

[0069] Preferably, Figure 3-5As shown, the buffer body is provided with a third material reduction groove 703, and the third material reduction groove 703 is arranged on the rear side of the fan blade cover groove 101. The third material reduction groove 703 and the support part groove 401 are respectively arranged on the left and right sides of the casing groove 301, and the third material reduction groove 703 is located in the middle in the up and down direction.

[0070] In the front-to-back direction, the projection of the fan blade cover 1 is larger than the projection of the casing 3, and the base groove and the support groove are located on the same side of the casing groove 301, so the third material reduction groove 703 is set on the other side of the casing groove 301, which can not only further reduce material consumption and reduce weight. Furthermore, the opening of the third material reduction groove 703 is set on the right end face and the rear end face of the buffer body, further reducing the consumption of vibration damping materials. Furthermore, the openings of the third material reduction groove 703 and the second material reduction groove 702 are respectively set on the left and right end faces of the buffer body, so the third material reduction groove 703 and the second material reduction groove 702 can be used for the hand-held position of the buffer body (including the various components of the floor fan that have been packaged) for easy handling. Reinforcing ribs can be set in the third material reduction groove 703 to improve the structural strength.

[0071] Preferably, Figure 5 As shown, in the up-down direction, a fourth material reducing groove 704 is provided in an area of ​​the upper surface of the buffer body corresponding to the second material reducing groove 702 .

[0072] The fourth material reduction groove 704 can not only reduce weight and materials, but also be used to place accessories of the floor fan.

[0073] The buffer body is rectangular in shape as a whole. In order to reduce weight and materials, more material reduction grooves are set on the upper and lower surfaces while ensuring structural strength and vibration reduction requirements. The solid structure between adjacent material reduction grooves forms reinforcing ribs. For the lower bottom surface, the buffer body is subjected to greater pressure and collision probability. Four of the multiple reinforcing ribs support and reinforce the four corners respectively; for the upper top surface, in order to better protect the fan blade cover 1, two of the multiple reinforcing ribs support and reinforce the two corners closest to the fan blade cover groove 101, thereby improving the structural strength of the distance from the fan blade cover groove 101.

[0074] Preferably, Figure 4 As shown, the buffer body includes an upper packaging member 601 and a lower packaging member 602 which are combined together;

[0075] The fan blade cover groove 101 includes an upper fan blade groove arranged in the upper package 601 and a lower fan blade groove arranged in the lower package 602, and the base groove 201 includes an upper base groove arranged in the upper package 601 and a lower base groove arranged in the lower package 602.

[0076] The buffer body is set to be two upper and lower parts, and the blade groove and the base groove 201 are also divided into the upper package 601 and the lower package 602. When the blade cover 1 and the base 2 are packaged, the blade cover 1 and the base 2 are placed in the lower blade groove and the lower base groove of the lower package 602, and then the upper package is covered on the lower package from above. In this way, the convenience of disassembly of the packaging box is improved. Further, in the up and down direction, the height of the upper package 601 and the lower package 602 is the same. When the support portion groove 401, the connecting rod groove 501, the second material reduction groove 702 and the third material reduction groove 703 are provided, the support portion groove 401, the connecting rod groove 501, the second material reduction groove 702 and the third material reduction groove 703 are divided into two upper and lower parts, respectively formed on the upper package 601 and the lower package 602.

[0077] Specifically, in the up-down direction, the depth of the second material reduction groove 702 on the upper package 601 is about 2 / 3 of the overall height of the upper package 601, which not only reduces the material used for the upper package 601, but also avoids excessive material reduction, which results in the area corresponding to the second material reduction groove 702 being too thin and insufficient structural strength. In the front-to-back direction, the projection of the connecting rod groove 501 partially overlaps with the projection of the base groove, and the depth of the second material reduction groove 702 is about 1 / 2 of the overall thickness of the buffer body, so as to ensure that the base groove has sufficient structural strength.

[0078] Specifically, in the up and down direction, the depth of the third material reduction groove 703 in the upper package 601 is 1 / 3 to 1 / 2 of the overall thickness of the upper package 601 , and similarly, the depth of the third material reduction groove 703 in the lower package 602 is 1 / 3 to 1 / 2 of the overall thickness of the lower package 602 .

[0079] Preferably, Figure 5 As shown, the base 2 includes an upper surface facing the fan blade cover 1 and a lower surface facing the ground, the upper surface of the base 2 is a convex surface, and the lower surface is provided with a friction elastic portion 202; the base groove 201 is provided with an opening facing rearward and a concave surface facing forward and capable of fitting with the convex surface, when the base 2 is arranged in the base groove 201, the lower surface of the base 2 faces rearward, the bottom surface of the friction elastic portion 202 facing rearward is flush with the rear surface of the buffer body, and the convex surface of the base fits with the concave surface of the base groove 201.

[0080] Since the friction elastic part 202 is provided on the lower surface of the base 2, when the floor fan is in working state, the lower surface of the base 2 can have a certain friction with the ground, thereby improving the stability of the floor fan during operation; the friction elastic part 202 also has a vibration reduction function, thereby avoiding unnecessary noise between the base 2 and the ground when the floor fan is working.

[0081] The rearward bottom surface of the friction elastic part 202 is flush with the rear surface of the buffer body, so that the front-to-back dimension of the buffer body is further reduced. Due to the arrangement of the friction elastic part, after the floor fan is disassembled and packaged by the buffer body, the friction elastic part 202 on the lower surface of the base 2 can protect the base 2. It is easy for those skilled in the art to understand that, under the premise of no conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0082] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. The above description is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present invention.
