Description

Technical Field

[0001] The present invention relates to the technical field of motor packaging, and in particular to a knife-clip assembly and a motor packaging structure. Background Art

[0002] During the transportation of motors, it is crucial to ensure that the motors are safe and undamaged. Although traditional motor packaging methods, such as blister packaging boxes, can provide a certain degree of protection, their high cost has become a challenge faced by many companies.

[0003] In order to solve this problem and take into account both cost-effectiveness and protection effects, the knife-card structure as an innovative way of motor packaging has gradually attracted attention. For example, the Chinese utility model patent with Chinese patent number ZL201921439210.5 discloses an environmentally friendly packaging box for motor packaging, please refer to Figure 8 , through the ingenious design of the first fixed blade card 4 and the second fixed blade card 5, the effective fixation and protection of the motor is achieved. Specifically, the first fixed blade card 4 and the second fixed blade card 5 are respectively provided with a plurality of first installation grooves 41 and a plurality of second installation grooves 51 in the shape of arcs. When the first fixed blade card 4 and the second fixed blade card 5 are aligned, the first installation groove 41 and the second installation groove 51 can be precisely docked to form a circular installation position. This design simplifies the installation and disassembly process and improves the use efficiency of the packaging box. However, in the environmentally friendly packaging box for motor packaging, multiple installation positions are integrated on the first fixed blade card 4 and the second fixed blade card 5, and each motor installation position cannot be adjusted independently, resulting in poor variability and flexibility. This means that when dealing with motors of different sizes and shapes, the entire blade card structure may need to be replaced, which limits its scope of application to a certain extent. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a knife-card assembly and a motor packaging structure which are highly flexible and can be combined according to the sizes of different motors.

[0015] Furthermore, the first knife card and the second knife card are both pre-folded from pre-folded plates, and there are folds between the first inner plate and the first top plate, between the first top plate and the first outer plate, between the second inner plate and the second top plate, and between the second top plate and the second outer plate.

[0016] In order to solve the above technical problems, another technical solution adopted by the present invention is: providing a motor packaging structure, including a knife card structure, wherein the knife card structure is configured to include:

[0017] The frame has two horizontal blade clamps and two first vertical blade clamps, the two ends of the two first vertical blade clamps are respectively connected to the two ends of the two horizontal blade clamps, and the two horizontal blade clamps are provided with a plurality of first clamping positions along the horizontal direction;

[0038] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0039] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0041] See also Figure 1 and Figure 2 , Figure 1 A structural schematic diagram of an embodiment of a motor packaging structure of the present invention is shown. Figure 2 A packaging state diagram of an embodiment of a motor packaging structure of the present invention is shown. Figure 1 In the illustrated embodiment, the motor packaging structure includes a box body (not shown) and a knife-card structure placed in the box body for assembling a motor A (especially a long-axis motor A). The box body is used to protect the knife-card structure and the motor A and facilitate stacking, handling and transportation. The knife-card structure includes a frame 100, a plurality of second longitudinal knife cards 200 disposed in the frame 100, and a plurality of knife-card assemblies 300 assembled on the second longitudinal knife cards 200. Each set of the knife-card assemblies 300 is used to assemble one motor A.

[0042] The enclosure 100 is a rectangular structure as a whole, and has a space that runs through in the vertical direction (height direction). The enclosure 100 has two horizontal blade clips 110 and two first vertical blade clips 120, and the two ends of the two first vertical blade clips 120 are respectively connected to the two ends of the two horizontal blade clips 110. The two horizontal blade clips 110 are configured to have a length smaller than the length of the two first vertical blade clips 120. When the two horizontal blade clips 110 and the two first vertical blade clips 120 are assembled into the enclosure 100, the two horizontal blade clips 110 are configured as the two end walls of the enclosure 100, and the two first vertical blade clips 120 are configured as the two side walls of the enclosure 100.

[0043] See also Figure 3 , both ends of the two horizontal blade cards 110 are provided with third clamping positions 111 for assembling the corresponding first vertical blade cards 120, and each of the third clamping positions 111 is configured as a clamping slot formed by the upper edge of the corresponding horizontal blade card 110 opening downward. Correspondingly, both ends of the two first vertical blade cards 120 are provided with fourth clamping positions 121 for assembling with the corresponding third clamping positions 111. Both ends of the two first vertical blade cards 120 are clamped with the third clamping positions 111 through the fourth clamping positions 121, that is, both ends of each first vertical blade card 120 are clamped with the two opposite third clamping positions 111 on the two horizontal blade cards 110 through the fourth clamping positions 121, so that the two first vertical blade cards 120 and the two horizontal blade cards 110 are enclosed to form the enclosure 100.

[0044] A plurality of first clamping positions 112 are distributed along the transverse direction on the two horizontal blade cards 110, and each of the two opposite first clamping positions 112 on the two horizontal blade cards 110 is used for assembling the two ends of the corresponding second longitudinal blade card 200. Each of the first clamping positions 112 is configured as a clamping slot formed by the lower edge of the horizontal blade card 110 to which it belongs. Correspondingly, the plurality of second longitudinal blade cards 200 are distributed in the enclosure 100 at intervals along the transverse direction of the enclosure 100, and the distribution spacing of the plurality of second longitudinal blade cards 200 is determined according to the spacing of the first clamping positions 112. The two ends of each of the second longitudinal blade cards 200 are provided with a second clamping position 210 that is clamped with the first clamping position 112, and each of the second clamping position 210 is configured as a clamping slot formed by the upper edge of the second longitudinal blade card 200 to which it belongs. The two ends of each of the second longitudinal blade cards 200 are clamped with the corresponding first clamping positions 112 on the two horizontal blade cards 110 through the second clamping positions 210.

[0045] When each second longitudinal blade clamp 200 is clamped with the two transverse blade clamps 110, the opening of the second clamping position 210 of the second longitudinal blade clamp 200 can be facing upward, and the second clamping position 210 can be clamped into the first clamping position 112 with the opening facing downward from bottom to top. The height of the plurality of second longitudinal blade clamps 200 is lower than the height of the enclosure 100. When the plurality of second longitudinal blade clamps 200 are assembled in the enclosure 100, the lower edge of the second longitudinal blade clamp 200 and the lower edge of the enclosure 100 can be located in the same plane, and the upper edge of the second longitudinal blade clamp 200 is lower than the upper edge of the enclosure 100, so that the enclosure 100 has a accommodating space 130 higher than the plurality of second longitudinal blade clamps 200. Those skilled in the art will appreciate that, in addition to the above-mentioned clamping method, the second longitudinal knife card 200 may also be assembled in the frame 100 in other ways, by simply making the upper edge of the second longitudinal knife card 200 lower than the upper edge of the frame 100 to leave a accommodating space 130 for the frame 100.

[0046] In this embodiment, each of the second longitudinal knife cards 200 has a plurality of second fixed positions 220 distributed along the longitudinal direction thereof, and the plurality of second fixed positions 220 are located between the second positions 210 at both ends. Each second fixed position 220 on each second longitudinal knife card 200 is arranged opposite to the corresponding second fixed position 220 on other second longitudinal knife cards 200 along the transverse direction. The second fixed position 220 is used to engage with the corresponding knife card assembly 300 to fix the knife card assembly 300; when the knife card assembly 300 is fixed at the second fixed position 220, it is accommodated in the accommodation space 130.

[0047] See also Figure 4 , Figure 5 and Figure 6, the knife card assembly 300 is arranged on the second longitudinal knife card 200 along the longitudinal direction of the enclosure 100. Each group of knife card assemblies 300 occupies two second longitudinal knife cards 200 in the transverse direction, that is, each group of knife card assemblies 300 is clamped on the corresponding second fixed clamping positions 220 of two adjacent second longitudinal knife cards 200, which can increase the stability of the knife card assembly 300 clamped on the second longitudinal knife card 200, and at the same time, more space can be saved to assemble more knife card assemblies 300. Of course, the knife card assembly 300 can also occupy more than two second longitudinal knife cards 200 in the transverse direction.

[0048] The knife card assembly 300 includes a first knife card 310 and a second knife card 320 which are arranged opposite to each other along the length direction of the second longitudinal knife card 200. The first knife card 310 includes a first inner plate 311, a first outer plate 312, and a first top plate 313 connected to the top of the first inner plate 311 and the first outer plate 312, the first inner plate 311 is provided with a first inner clamping position 311a, and the first outer plate 312 is provided with a first outer clamping position 312a. The second knife card 320 includes a second inner plate 321, a second outer plate 322, and a second top plate 323 connected to the top of the second inner plate 321 and the second outer plate 322, the second inner plate 321 is provided with a second inner clamping position 321a. When the first knife clamp 310 and the second knife clamp 320 are arranged relative to each other, the first inner plate 311 and the second inner plate 321 are close to each other, so that the first inner clamping position 311a and the second inner clamping position 321a are combined to form a main body clamping position for accommodating the main body A1 of the motor A; the first outer plate 312 and the second outer plate 322 are far away from each other, so that the first outer clamping position 312a at the first outer plate 312 forms a first shaft clamping position for accommodating the output shaft A2 of the motor A.

[0049] Preferably, the second outer plate 322 is further provided with a second outer clamping position 322a, which is used to accommodate the second axis clamping position of the output shaft A2 of another adjacent motor A. The advantage of such a setting is that the width of the first knife clamp 310 (the dimension along the direction of the output shaft A2 of the motor A) is used to support the end of the output shaft A2 of another adjacent motor A away from the main body A1 of the motor A, so that the second outer clamping position 322a of the knife clamp assembly 300 and another set of knife clamp assemblies 300 form a three-point support (one is the main body clamping position, the second is the first axis clamping position, and the third is the second axis clamping position) for supporting and clamping another motor A, which is suitable for clamping the long-axis motor A, and can make the arrangement between the knife clamp assemblies 300 more compact without affecting the number of long-axis motors A to be clamped, so that more knife clamp assemblies 300 can be clamped on the second longitudinal knife clamp 200, saving space, reducing costs, reducing the number of handling and transportation, improving efficiency, saving labor costs, and saving manufacturing costs. Based on this solution, more preferably, the two horizontal blade clamps 110 are further provided with a plurality of fifth clamping positions 113 (see Figure 1 and Figure 2 ), each fifth clamping position 113 is configured as a clamping slot formed by opening downward from the upper edge of the corresponding horizontal blade clamp 110. The position and size of each fifth clamping position 113 are adapted to the corresponding first axis clamping position or second axis clamping position, so as to be clamped in the output shaft A2 of the motor A close to the horizontal blade clamp 110 and away from the main body A1.

[0050] The first inner clamping position 311a penetrates the first inner side plate 311 upward along the vertical direction. The first top plate 313 is also provided with a first opening 313a penetrating the first top plate 313 along the vertical direction, and the first opening 313a is connected to the first inner clamping position 311a. The second inner clamping position 321a penetrates the second inner side plate 321 upward along the vertical direction. The second top plate 323 is also provided with a second opening 323a penetrating the second top plate 323 along the vertical direction, and the second opening 323a is connected to the second inner clamping position 321a. When the main body A1 of the motor A is clamped in the main body clamping position, the main body A1 of the motor A passes through the first opening 313a and the second opening 323a arranged side by side from top to bottom, and is accommodated in the first inner clamping position 311a and the second inner clamping position 321a.

[0051] The first outer stopper 312a vertically penetrates the first outer plate 312 upward; the first top plate 313 is also provided with a third opening 313b vertically penetrating the first top plate 313, the third opening 313b is connected to the first opening 313a, and the third opening 313b is also connected to the first outer stopper 312a. The first inner stopper 311a, the first opening 313a, the third opening 313b and the first outer stopper 312a are collinear (located on the same straight line) along the center line L1 in the axial direction of the motor A. The second outer stopper 322a vertically penetrates the second outer plate 322, the second top plate 323 is also provided with a fourth opening 323b vertically penetrating the second top plate 323, the fourth opening 323b is connected to the second opening 323a, and the fourth opening 323b is also connected to the second outer stopper 322a. The second inner clamping position 321 a , the second opening 323 a , the fourth opening 323 b and the second outer clamping position 322 a are collinear with a center line L1 along the axial direction of the motor A, and are collinear with the center line L1 of the first blade clamp 310 .

[0052] A plurality of first fixed card positions 301 are also provided on the first inner plate 311 and the first outer plate 312 of the first knife card 310, and the second inner plate 321 and the second outer plate 322 of the second knife card 320. The plurality of first fixed card positions 301 are distributed on the corresponding side plates at intervals along a direction (transverse direction) perpendicular to the distribution direction (longitudinal direction) of the first knife card 310 and the second knife card 320; each first fixed card position 301 is configured as a card slot opened upward from the bottom edge of the corresponding side plate.

[0053] In this embodiment, two first fixed positions 301 are arranged at intervals along the transverse direction on the first outer plate 312, two first fixed positions 301 are arranged at intervals along the transverse direction on the first inner plate 311, two first fixed positions 301 are arranged at intervals along the transverse direction on the second outer plate 322, and two first fixed positions 301 are arranged at intervals along the transverse direction on the second inner plate 321. The two first fixed positions 301 on each side plate are aligned with the two first fixed positions 301 on each other side plate, and the two first fixed positions 301 on each side plate are engaged with the corresponding second fixed positions 220 on each two second longitudinal knife clamps 200. The four pairs of first fixed positions 301 distributed along the longitudinal direction on each set of knife clamp components 300 are engaged with the four pairs of second fixed positions 220 on the corresponding second longitudinal knife clamps 200. In this way, each set of knife card assemblies 300 is mounted on the second longitudinal knife card 200 at multiple points in both the longitudinal and transverse directions, ensuring the stability of each set of knife card assemblies 300, preventing the knife card assemblies 300 from tipping over or collapsing during transportation, ensuring the fixed stability of the motor A, and preventing the motor A from being damaged during transportation.

[0054] See also Figure 7 In this embodiment, the first knife card 310 and the second knife card 320 are both pre-folded from a pre-folded plate, and the pre-folded plate can be configured as a pre-folded paperboard 30. There are folds 33 between the first inner plate 311 and the first top plate 313, between the first top plate 313 and the first outer plate 312, between the second inner plate 321 and the second top plate 323, and between the second top plate 323 and the second outer plate 322. When processing the pre-folded paperboard 30:

[0055] First, the cardboard is cut according to the final forming size of the knife card to form a cardboard that matches the knife card; in this embodiment, the cut cardboard is in a rectangular shape;

[0056] Secondly, grooves are formed at both ends of the paperboard to form first fixed clamping positions 301; wherein, two first fixed clamping positions 301 spaced apart along the width direction of the paperboard are formed at each end of the paperboard, and the spacing distance thereof matches the spacing distance between each two second longitudinal knife clamps 200, and each first fixed clamping position 301 is formed from the end of the paperboard to the center along the length direction thereof;

[0057] Next, taking the center line L2 on the paperboard parallel to the width direction as a reference, a rectangular first cavity 31 is processed at a position close to one end of the center line L2, and the first cavity 31 penetrates the paperboard along the thickness direction of the paperboard;

[0058] Then, a second long cavity 32 is processed along the length direction of the paperboard, and the second cavity 32 is connected to an end of the first cavity 31 close to the center line L2; and the center line L1 parallel to the length direction of the second cavity 32 is collinear with the center line L1 of the first cavity 31;

[0059] Finally, taking the center line L2 on the paperboard parallel to the width direction as a reference, two folds 33 parallel to the center line L2 are processed on both sides of the center line L2, one of which is located at the first cavity 31 and perpendicular to its length direction, and the other fold 33 is located at the second cavity 32 and perpendicular to its length direction. One of the folds 33 is closer to the end of the first cavity 31 facing the center line L2, and the other fold 33 is closer to the end of the second cavity 32 away from the first cavity 31. The two folds 33 divide the paperboard into three areas, wherein the area in the middle forms a top plate (first top plate 313 or second top plate 323) after folding into a knife card, and the areas on both sides form inner side plates (first inner side plate 311 or second inner side plate 321) and outer side plates (first outer side plate 312 or second outer side plate 322). When the paperboard is bent along one of the folds 33, the one of the folds 33 divides the first cavity 31 into a vertically distributed inner position (the first inner position 311a or the second inner position 321a) and a horizontally distributed opening (the first opening 313a or the second opening 323a). When the paperboard is bent along the other fold 33, the other fold 33 divides the second cavity 32 into a vertically distributed outer position (the first outer position 312a or the second outer position 322a) and a horizontally distributed opening (the third opening 313b or the fourth opening 323b).

[0060] Those skilled in the art will appreciate that the processing steps of the paperboard are not limited to the steps in the order shown above. In different embodiments, the steps can be interchanged according to actual needs.

[0061] Based on the implementation shown above, the knife clamp structure can be assembled as follows: (1) The fourth clamping position 121 at the end of the two first longitudinal knife clamps 120 is clamped into the third clamping position 111 corresponding to the end of the two horizontal knife clamps 110, so that the two first longitudinal knife clamps 120 and the two horizontal knife clamps 110 are assembled together to form the frame 100; (2) The second clamping position 210 at the end of each second longitudinal knife clamp 200 is clamped into the corresponding first clamping position 112 on the two horizontal knife clamps 110, so that a plurality of second longitudinal knife clamps 200 are clamped in the space enclosed by the frame 100 along the horizontal direction; (3) Every two second longitudinal knife clamps 200 are used as a combination for installing the knife clamp assembly 300, so that a plurality of groups of knife clamp assemblies 300 are clamped on the combination at intervals along the length direction of the second longitudinal knife clamps 200; wherein, the first fixed clamping position 301 on each knife clamp is correspondingly clamped at the second fixed clamping position 220 at the corresponding position of the two second longitudinal knife clamps 200.

[0062] In summary, the knife card assembly 300 and the motor packaging structure of the present invention have the following beneficial effects compared with the prior art: (1) The knife card assembly 300 is an independent and compatible card assembly corresponding to the size and number of motors A, and can be customized according to the size and number of motors A and the shape and size of the frame 100, thereby improving the flexibility of motor A assembly and the variability of assembly position; motors A of the same model can be assembled in the same box, and motors A of different models or sizes can be assembled in the same box according to needs, thereby expanding the scope of application and versatility of motor A packaging; and each set of knife card assemblies 300 can be arranged more closely, thereby reducing the occupied space. (2) The knife card assembly 300 is composed of two first knife cards 310 and second knife cards 320 arranged opposite to each other, and can be applied to motors A of different lengths, and only the distance between the first knife card 310 and the second knife card 320 needs to be adjusted. (3) The second outer clamping position 322a provided on the knife clamp assembly 300 can be used for clamping the motor A with a longer output shaft A2 without increasing the distance between the two knife clamps; and the second outer clamping position 322a can also increase the support points, improve the support stability, and at the same time make the arrangement between the knife clamp assemblies 300 more compact, without affecting the number of long-axis motors A that can be clamped, so that more knife clamp assemblies 300 can be clamped on the second longitudinal knife clamp 200, saving space, reducing costs, reducing the number of handling and transportation, improving efficiency, saving labor costs, and saving manufacturing costs. (4) Since each set of knife clamp assemblies 300 is independent, when assembled on the enclosure 100, its assembly position and assembly quantity can be adjusted in real time. Compared with the traditional method of only using the horizontal knife clamp 110 and the longitudinal knife clamp, the assembly method and flexibility of the knife clamp assembly 300 are greatly improved, which can be applied to the needs of more occasions, better meet the needs of users, and enhance the user's sense of use and experience. (5) The knife card assembly 300 is folded from pre-folded cardboard, and its shape, size, and structure can be adaptively adjusted according to different implementation methods, and can reduce manufacturing costs and packaging costs.

[0063] The above embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
