Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of impact buffering, in particular to a buffering structure, a packaging box using the buffering structure, and a product assembly using the packaging box. BACKGROUND

[0002] A buffering structure is usually arranged in a packaging box to buffer a product contained in the packaging box during transportation. However, when a spring is used for buffering in the buffering structure of the packaging box, the spring usually supports the product. At this time, when the product in the packaging box shakes, the spring is bent and tilted by the gravity of the product when the spring is vertically arranged. When the spring is horizontally arranged, the spring is also bent by the gravity of the product. Therefore, it can be said that the spring in the buffering structure is bent by the gravity of the product, which affects the normal stable release of the spring and affects the elastic buffering and elastic resetting of the buffering structure, so that the final buffering effect of the buffering structure is relatively low. SUMMARY

[0011] Optionally, the bearing seat is detachably arranged on the movable carrier, and the buffer structure further comprises a limiting ring, the limiting ring is connected to the connecting rope in at least two buffer assemblies, and is arranged around the movable carrier.

[0012] Optionally, the side of the bearing seat away from the fixed body is provided with a bearing groove.

[0013] Optionally, the movable carrier is in a ring structure, and the connecting ropes in at least two buffer assemblies are uniformly and spacedly arranged along the circumference of the movable carrier.

[0015] Optionally, the elastic member is a volute spring, and the volute spring is sleeved on the rotating shaft.

[0016] The volute spring has an inner connecting arm at the inner side end thereof and an outer connecting arm at the outer side end thereof, the inner connecting arm is connected to the rotating shaft, and the outer connecting arm is connected to the fixed body.

[0019] Optionally, the fixed body is formed with a mounting cavity, the movable carrier is located outside the mounting cavity, the rotating shaft and the volute spring are arranged in the mounting cavity, and a passing opening is further arranged on the cavity wall of the mounting cavity, and the connecting member connected to the rotating shaft and the movable carrier passes through the passing opening.

[0020] Optionally, when the fixed body is formed with a mounting cavity, a partition plate is arranged in the mounting cavity, the partition plate is connected to the cavity wall of the mounting cavity, and the rotating shaft is rotatably arranged through the partition plate.

Therefore, the features limited by "first" and "second" can explicitly or implicitly include at least one of the features.

[0044] Please refer to Figures 1-5 The present application provides a buffering structure 100, in an embodiment of the present application, the buffering structure 100 includes a mounting carrier 10 and a buffering assembly 30. The mounting carrier 10 includes a fixed body 11 and a movable carrier 13, the movable carrier 13 and the fixed body 11 are spaced apart; the number of the buffering assembly 30 is at least two, the at least two buffering assemblies 30 are distributed around the movable carrier 13, each buffering assembly 30 includes a moving piece 31, a connecting piece 33 and an elastic piece 35; the moving piece 31 is movably arranged on the fixed body 11, one end of the connecting piece 33 is connected to the moving piece 31, and the other end is connected to the movable carrier 13, so that the moving piece 31 is driven to move when the movable carrier 13 moves relative to the fixed body 11, and the elastic piece 35 is used to drive the moving piece 31 to move back to the original position.

[0045] The fixed body 11 of the mounting carrier 10 can serve as the main structure of the buffer structure 100, so that other components of the buffer structure 100 can be mounted on the mounting carrier 10 to form an integral structure. The fixed body 11 can be a regular cuboid or a rectangular cuboid, so that it is regular in shape and easy to process. Of course, the present application is not limited thereto, and in other embodiments, the fixed body 11 can also be a cylindrical structure or other shapes. The movable carrier 13 can be used to provide a mounting position for the product to be mounted and supported. Since the movable carrier 13 can move relative to the fixed body 11, when the product is impacted, the movable carrier 13 can move with the product. That is, the impact force on the product can be transmitted to the movable carrier 13, so that when the impact force on the movable carrier 13 is buffered, the impact on the product is also buffered. The movable carrier 13 can be a regular cuboid or a ring, so that it is regular in shape and easy to process. Of course, the present application is not limited thereto, and in other embodiments, the movable carrier 13 can also be a cylindrical structure or other shapes. The number of buffer assemblies 30 can be at least two, so as to buffer the impact on the movable carrier 13 in multiple directions, thereby improving the buffering effect of the buffer structure 100. For example, the number of buffer assemblies 30 can be four and arranged at uniform intervals around the movable carrier 13. At this time, the buffer assembly 30 can have a buffering effect on the impact in each direction around it; at the same time, the number of buffer assemblies 30 is not too much, so that the overall structure of the buffer structure 100 is not too complex, thereby balancing the buffering effect and manufacturing convenience. Of course, it should be noted that the present application is not limited thereto, and in other embodiments, the number of buffer assemblies 30 can be two, three, five or more. The moving part 31 shaft of the buffer assembly 30 can be used to convert the movement of the movable carrier 13 into the movement of the moving part 31 when the movable carrier 13 is impacted and driven, in other words, so that the elastic member 35 does not have a direct connection with the movable carrier 13, avoiding the elastic member 35 being affected by the gravity of the product when the movable carrier 13 is mounted with the product, causing the elastic member 35 to be bent under pressure and affecting the subsequent buffering of the impact and the resetting of the moving part 31 and the movable carrier 13. The connecting member 33 can be used to connect the movable carrier 13 and the moving part 31, so that when the movable carrier 13 moves following the impact of the product, the movement can be transmitted to the moving part 31, realizing the conversion of the movement of the movable carrier 13 into the movement of the moving part 31. The elastic member 35 has elasticity, so that when the moving part 31 is driven to move by the movable carrier 13, the elastic member 35 can be elastically deformed and generate a corresponding elastic force.At this time, the deformation elastic force can dampen the rotation of the moving piece 31, so as to hinder the rotation of the moving piece 31 and the movement impact of the movable carrier 13. In other words, the impact force on the movable carrier 13 is converted into the elastic potential energy of the elastic piece 35 for storage, and then after the buffering is completed, the elastic piece 35 can drive the moving piece 31 and the movable carrier 13 to reset by releasing the elastic potential energy.

[0046] When the buffering structure 100 of the technical scheme is used, the movable carrier 13 of the mounting carrier 10 can move relative to the fixed main body 11 after being subjected to a collision impact force. At this time, at least one connecting piece 33 in the buffering assembly 30 is pulled by the movable carrier 13, thereby driving the corresponding moving piece 31 to move. The elastic piece 35 corresponding to the moving piece 31 can be elastically deformed during the driving of the moving piece 31 by the movable carrier 13, so as to dampen the driving of the moving piece 31 by the movable carrier 13 through the deformation elastic force generated by the elastic piece 35, thereby achieving the buffering of the impact force received by the movable carrier 13. Moreover, since the buffering structure 100 in the present scheme supports the product to be installed by the movable carrier 13, the connecting piece 33 and the moving piece 31, and the elastic piece 35 is only used to drive the moving piece 31 to rotate and reset, it is not necessary to support the product installed on the movable carrier 13. Therefore, compared with the buffering structure in the prior art which supports the product by a spring, the elastic piece 35 of the buffering structure 100 in the present scheme will not be subjected to the pressure bending phenomenon due to the gravity of the product, thereby affecting the subsequent elastic buffering and elastic resetting work. That is, the elastic piece 35 in the buffering structure 100 in the present scheme can more normally and stably perform the buffering and resetting work, thereby improving the buffering effect of the buffering structure 100. Moreover, since the buffering structure 100 in the present scheme also relies on a series of mechanical mechanisms such as the moving piece 31, the connecting piece 33 and the elastic piece 35 to achieve the buffering purpose, it also replaces some buffering methods which directly use the EPE, PET and PVC buffering materials which are difficult to degrade and are one-time materials, so that the user can repeatedly use the buffering structure 100 in the present scheme, thereby also being beneficial to improving the environmental protection of the buffering structure 100.

[0047] Please refer to Figures 4-6 In an embodiment of the present application, the moving piece 31 is a rotating shaft 311, which is rotatably arranged on the fixed main body 11 and is driven to rotate when the movable carrier 13 moves relative to the fixed main body 11.

[0048] In the embodiment, the moving piece 31 is arranged as a rotating shaft 311 structure, so that the moving track of the moving piece 31 is circular. Compared with the linear moving track of the rotating shaft 311 arranged as sliding, the circular moving track of the rotating shaft 311 arranged as rotating can make the moving piece 31 always move on the mounting position, without the need of certain moving space due to the similar sliding arrangement, and thus it is not necessary to arrange the moving space on the fixed body 11 for avoiding the movement of the moving piece 31, thereby facilitating to improve the compactness of the distribution of the moving piece 31 on the fixed body 11, so as to reduce the overall volume of the buffer structure 100 and make it more convenient to install. It should be noted that, as shown in Figure 5 the buffer structure 100 is normally used in the packaging box, the rotating direction of the rotating shaft 311 can surround an axis parallel to the up-down direction, and the movable carrier 13 can move in the horizontal direction (including the case of moving in one direction or at least two directions on the horizontal plane), and of course, it can further move in the up-down direction on the basis of moving in the horizontal direction. The rotating shaft 311 can be an equal-diameter shaft body. Of course, the rotating shaft 311 can also be formed by combining at least two shaft body segments with different diameters. Alternatively, the rotating shaft 311 is formed by combining a shaft body segment and a square body segment; at this time, the shaft body segment of the rotating shaft 311 is rotationally connected. In addition, it should be noted that the present application is not limited to this, and in other embodiments, the moving piece 31 can also be a sliding block, which is slidably arranged on the fixed body 11 and is driven to slide when the movable carrier 13 moves relative to the fixed body 11.

[0049] Please refer to Figures 4-6 , in an embodiment of the present application, the connecting piece 33 is a connecting rope 331, and one end of the connecting rope 331 away from the movable carrier 13 is wound on the rotating shaft 311, so that the movable carrier 13 can drive the rotating shaft 311 to rotate when the connecting rope 331 is pulled.

[0050] In the embodiment, the connecting rope 331 is used as the connecting member 33, and the connecting rope 331 has good flexibility, so that one end of the connecting rope 331 is directly wound on the rotating shaft 311, and the other end is connected with the movable carrier 13, so that the connection between the connecting member 33 and the rotating shaft 311 and the movable carrier 13 can be achieved very quickly, and a relatively complex connection structure between the connecting member 33, the movable carrier 13 and the rotating shaft 311 does not need to be additionally arranged. Moreover, the structure of the connecting rope 331 itself is also very simple. Therefore, the connecting rope 331 is used as the connecting member 33, so that the structure of this part can be greatly simplified, so as to improve the convenience of processing the buffer structure 100. The connecting rope 331 can be wound on the rotating shaft 311 for half a turn, one turn, two turns or more turns, and the specific number of turns can be adaptively set according to the size of the impact force that the mounting carrier 10 can bear, and the application does not make a specific limitation on this. The connecting rope 331 and the movable carrier 13 can be connected by adhesive fixing, screw connection or winding and knotting, and the application does not make a specific limitation on this, and the connecting rope 331 and the movable carrier 13 can be connected. In addition, it should be noted that the application is not limited to this, and in other embodiments, the connecting member 33 can also be a connecting rod assembly, for example, the connecting rod assembly can include a first connecting rod and a second connecting rod, the first connecting rod is rotatably connected to the movable carrier 13, one end of the second connecting rod is rotatably connected to the end of the first connecting rod away from the movable carrier 13, and the other end is rotatably connected to the moving piece 31, and the first connecting rod and the second connecting rod are arranged at an angle. At this time, when the movable carrier 13 moves, the moving piece 31 can be driven to rotate or slide through the connecting rod assembly.

[0051] Further, the material of the movable carrier 13 is a hard material, please refer to Figure 1 and Figure 2 , the buffer structure 100 further includes a bearing seat 50, the material of the bearing seat 50 is a flexible material, and the bearing seat 50 is arranged on the side of the movable carrier 13 away from the fixed main body 11.

[0052] When the connecting rope 331 is used as the connecting member 33, the movable carrier 13 is hung and installed by the connecting rope 331. At this time, the connecting rope 331 exerts a certain tension on the movable carrier 13. Therefore, in order to avoid the deformation of the movable carrier 13 when the connecting rope 331 is hung and installed in tension, the initial state of the elastic member 35 in each buffer assembly 30 is different, which affects the buffering effect of part of the buffer assemblies 30. In the embodiment, the material of the movable carrier 13 is a hard material, so that the movable carrier 13 does not deform when it is hung and installed in tension by the connecting rope 331, thereby ensuring the accurate installation of the movable carrier 13. Moreover, the material of the movable carrier 13 is set to be a hard material, which can also better support the product. Specifically, the material of the movable carrier 13 can be metal, and of course can also be a hard plastic. When the material of the movable carrier 13 is a hard material, the movable carrier 13 and the product are in hard abutment, and the two may rub against each other and cause wear to the surface of the product. Therefore, in order to improve the protection of the product, a bearing seat 50 made of a flexible material can be arranged on the movable carrier 13, so as to arrange the product through the bearing seat 50, avoiding the direct hard contact between the product and the movable carrier 13. Specifically, the material of the bearing seat 50 can be paper plastic, rubber or silicone, etc.

[0053] Please refer to Figure 1 and Figure 2 In an embodiment of the present application, the bearing seat 50 is detachably arranged on the movable carrier 13, and the buffer structure 100 further comprises a limiting stop ring 70, which is connected to the connecting rope 331 in at least two buffer assemblies 30 and arranged around the movable carrier 13.

[0054] In the embodiment, the bearing seat 50 and the movable carrier 13 are detachably arranged, so that when facing products of different sizes, the bearing seat 50 can be replaced, so that the buffer structure 100 can be adapted to support and buffer a certain product, thereby improving the practicability of the buffer structure 100 for different products. At this time, the product can be more conveniently reused, further improving the environmental protection of the buffer structure 100. The limiting stop ring 70 and the connecting rope 331 can be fixed by adhesion, so as to simplify the connection process of the two. The material of the limiting stop ring 70 can also be a hard material, such as metal or hard plastic, etc.

[0055] Please refer to Figure 1 or Figure 2 In an embodiment of the present application, the bearing seat 50 is provided with a bearing groove 51 on the side away from the fixed body 11.

[0056] In the embodiment, the bearing groove 51 is arranged on the bearing seat 50, so that part of the structure of the product can be arranged in the bearing groove 51. Then, the product can be abutted and limited by the groove side wall of the bearing groove 51, thereby facilitating to improve the stability of the product arranged on the bearing seat 50.

[0057] Please refer to Figure 2 Or Figure 3 In an embodiment of the present application, the movable carrier 13 is in a ring structure, and the connecting ropes 331 in the at least two buffer assemblies 30 are arranged in a uniform interval along the circumference of the movable carrier 13.

[0058] In the embodiment, the movable carrier 13 is in a ring structure, so that the movable carrier 13 does not need to be perforated for the connecting ropes 331 to pass through and be connected, thereby facilitating to simplify the structure of the movable carrier 13. Moreover, at this time, the inner side of the movable carrier 13 is equivalent to being perforated, so that the movable carrier 13 is relatively light, thereby facilitating the connecting ropes 331 to be hung and installed, and avoiding the risk of the connecting ropes 331 being broken due to overloading.

[0059] Please refer to Figure 4 In an embodiment of the present application, the movable carrier 13 can be in the same plane as the connecting ropes 331. At this time, the connecting ropes 331 between the movable carrier 13 and the rotating shaft 311 can be linearly extended, and the path is relatively short, thereby guaranteeing that the movable carrier 13 can timely and effectively pull the connecting ropes 331 to timely drive the rotating shaft 311 to rotate when the movable carrier 13 moves. When the connecting ropes 331 are wound on the rotating shaft 311 for at least two turns, the connecting ropes 331 wound on the rotating shaft 311, the connecting ropes 331 not wound on the rotating shaft 311, and the movable carrier 13 are in the same plane.

[0060] Please refer to Figures 4-6 In an embodiment of the present application, the elastic member 35 is a volute spring 351, and the volute spring 351 is sleeved on the rotating shaft 311. The volute spring 351 has an inner connecting arm 353 at the inner side end and an outer connecting arm 355 at the outer side end, the inner connecting arm 353 is connected to the rotating shaft 311, and the outer connecting arm 355 is connected to the fixed main body 11.

[0061] In the embodiment, the elastic member 35 is a volute spring 351, which can be sleeved on the rotating shaft 311, thereby facilitating the installation of the elastic member 35. Moreover, the volute spring 351 itself has a relatively small size, and is sleeved, thereby making the structure compact. Of course, it should be noted that the present application is not limited to this, and in other embodiments, when the elastic member 35 is the rotating shaft 311, the elastic member 35 can also be a torsion spring. When the elastic member 35 is the sliding block, the elastic member can also be a tension spring or a compression spring.

[0062] Further, in order to simplify the connection between the volute spring 351 and the rotating shaft 311 and the fixed body 11, please refer to Figure 6 and Figure 7 , the rotating shaft 311 can be provided with a first clamping groove 313 at a position corresponding to the inner connecting arm 353, and the inner connecting arm 353 can be inserted into the first clamping groove 313. The fixed body 11 can be provided with a second clamping groove 111 at a position corresponding to the outer connecting arm 355, and the outer connecting arm 355 can be inserted into the second clamping groove 111. At this time, the inner connecting arm 353 and the outer connecting arm 355 of the volute spring 351 are aligned with the first clamping groove 313 and the second clamping groove 111 respectively, and then directly sleeved and installed, thereby quickly realizing the connection between the volute spring 351 and the rotating shaft 311 and the fixed body 11. Moreover, the insertion of the inner connecting arm 353 into the first clamping groove 313 and the outer connecting arm 355 into the second clamping groove 111 can make the volute spring 351 more compact, thereby further reducing the space occupation.

[0063] Please refer to Figure 3 and Figure 4 , in an embodiment of the present application, the fixed body 11 is formed with an installation cavity 112, the movable carrier 13 is located outside the installation cavity 112, and the rotating shaft 311 and the volute spring 351 are arranged in the installation cavity 112; the cavity wall of the installation cavity 112 is further provided with a passing opening 113, and the connecting member 33 connected to the rotating shaft 311 and the movable carrier 13 passes through the passing opening 113.

[0064] In the embodiment, the rotating shaft 311 and the volute spring 351 are arranged in the installation cavity 112, which can make the structure more compact on the fixed body 11, thereby further reducing the overall size of the buffer structure 100 and improving the subsequent installation convenience. At the same time, the cavity wall of the installation cavity 112 can also protect the rotating shaft 311 and the volute spring 351, thereby avoiding the possibility of damage by external objects and prolonging the service life of the rotating shaft 311 and the volute spring 351.

[0065] Further, please refer toFigures 4-6 The mounting cavity 112 is provided with a partition plate 114 connected to the cavity wall of the mounting cavity 112, and the rotating shaft 311 is rotatably arranged in the partition plate 114. The volute spring 351 is arranged on one of the opposite sides of the partition plate 114, and the connecting member 33 is arranged on the other of the opposite sides of the partition plate 114 at one end of the rotating shaft 311.

[0066] In the embodiment, the partition plate 114 can separate the connecting member 33 and the volute spring 351 to avoid mutual interference. In particular, when the connecting member 33 is a connecting rope 331, the partition plate 114 can ensure that the connecting rope 331 and the volute spring 351 work normally and stably. In addition, the partition plate 114 can also provide a mounting position for the rotating shaft 311, so that the rotating shaft 311 can be rotatably arranged in the partition plate 114, without the need to be inserted into the cavity wall of the mounting cavity 112 for rotation. In addition, the partition plate 114 can also provide a mounting position for the volute spring 351, so that the second clamping groove 111 can be arranged on the partition plate 114. That is, a protrusion can be arranged on the partition plate 114, the protrusion extends along the axial direction of the volute spring 351, and the second clamping groove 111 for connecting the outer connecting arm 355 of the volute spring 351 is arranged on the protrusion.

[0067] Further, please refer to Figure 5 and Figure 7 The number of partition plates 114 can be two, and the two partition plates 114 are arranged in a spaced manner along the axial direction of the rotating shaft 311. The connecting member 33 is arranged between the two partition plates 114 at one end of the rotating shaft 311. The number of volute springs 351 is two, and the two volute springs 351 are arranged on the opposite sides of the two partition plates 114.

[0068] In the embodiment, the number of volute springs 351 is two, so that the impact on the movable carrier 13 can be better buffered by the two volute springs 351, to further improve the buffering and resetting effect of the movable carrier 13. The two partition plates 114 can better separate the two volute springs 351 and the connecting member 33, and can also increase the abutting limiting effect of the rotating shaft 311 to improve the stability of the installation of the rotating shaft 311. Further, the spacing between the two partition plates 114 can be adjusted, so that when the connecting member 33 is a connecting rope 331, the connecting rope 331 can only be arranged in the area between the two partition plates 114, thereby improving the limiting effect of the arrangement position of the connecting rope 331 on the rotating shaft 311. In addition, the distance between the two partition plates 114 can be limited, so that the connecting rope 331 arranged at least two turns on the rotating shaft 311 can be located in the same plane.
