Description

Technical Field

[0001] This invention relates to the field of logistics packaging technology, specifically to an electronically controlled housing packaging structure assembly with a buffer positioning structure. Background Technology

[0002] Electrical control housings refer to the housing covers in automotive mechanical structures. To facilitate their production and transportation, they usually require appropriate packaging. Collapsible boxes are also a common packaging and transportation method. Collapsible boxes are a type of box structure. To improve the stability of the housing components inside the box and avoid collisions between the housings, it is common to add appropriate lining materials inside the collapsible box, such as honeycomb panel clips or inner sponge blocks.

[0003] However, the existing solutions are insufficient because the current lining material and the transported items inside the crate are usually in point or line contact. In other words, the actual contact area between the transported items and the lining material is small. This is more suitable for some small-sized automotive parts with high structural strength. However, the overall shape of the shell is large, and the shell is similar to a plate structure with an irregular outline. If there are too few support points or the contact area is too small, the shell is prone to bending and deformation. To solve the above problems, we propose a new packaging technology solution. Summary of the Invention

[0004] The purpose of this invention is to provide an electrical control housing packaging structure assembly with a buffer positioning structure to overcome the shortcomings of the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An electrical control housing packaging structure assembly with a buffer positioning structure includes a box housing that accommodates a housing cover. The box housing has multiple stacked partition structures. Each partition structure includes a bottom liner that can be adapted to the inner wall surface of the housing cover. The bottom surface of the bottom liner is fixed with a top limiting plate that can be adapted to the outer wall surface of the housing cover. A tolerance space that can be adapted to and limited by the housing cover is formed between two adjacent partition structures.

[0007] Preferably, the partition structure is a hollow plate structure adapted to the box body, the top surface of the bottom liner is provided with a contour groove adapted to the cover opening surface of the shell, and the bottom surface of the top limit plate is provided with a recessed groove adapted to the outer contour of the shell.

[0008] Preferably, both the bottom liner and the top limit plate are vacuum-formed panels, and both the bottom liner and the top limit plate have supporting edges on their circumferential contours. The space between the bottom liner and the top limit plate forms a buffer space in the partition structure.

[0009] Preferably, the bottom liner has multiple recessed openings on its top surface and the top limit plate has multiple protruding columns on its bottom surface. When multiple partition structures are stacked, the protruding columns of the upper partition structure can be inserted and adapted to the corresponding recessed openings below.

[0010] Preferably, the box body includes a bottom support plate, a side panel, and a box cover. The bottom support plate and the box cover are both double-layered structures formed by vacuum forming, and a tube frame structure is arranged inside the bottom support plate and the box cover.

[0011] Preferably, the box body is provided with a plurality of support rods that can move through the stacked partition structure, and the two ends of each support rod can be connected to the corresponding tray and the tube frame structure on the box cover.

[0012] Preferably, the pipe rack structure includes a main beam pipe, through which multiple branch pipes are fixedly inserted in the vertical direction. Each branch pipe has a through-hole on both sides that is adapted to be inserted into the end of a support rod. Each through-hole is provided with a locking pin that can limit the support rod extending into the branch pipe.

[0013] Preferably, a reinforcing rod is rotatably installed inside the main beam tube on the box cover. The reinforcing rod moves through each branch tube and is connected to the locking pin strip by a traction rope.

[0014] Preferably, the end side of the top of the support rod is provided with a half-groove that matches the locking pin.

[0015] Preferably, the box body is provided with a fastening rope, one end of which is connected to a locking pin on the box cover, and the other end of which is connected to a pin rod. The pin rod can cooperate with the locking pin of the tube frame structure in the bottom support plate to play a load-bearing role.

[0016] In the above technical solution, the present invention provides an electronically controlled housing packaging structure assembly with a buffer positioning structure. By arranging multiple partition structures composed of bottom liner plates and top limit plates in the box, the various shell covers in the box can be separated at intervals and can be adapted to support the inner and outer walls of the shell covers. This increases the contact area with the shell and the number of support points, enhances the support, effectively reduces the occurrence of shell cover deformation, and significantly reduces the damage rate of the shell during transportation.

Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Please see Figures 1-9 The present invention provides an electronic control housing packaging structure assembly with a buffer positioning structure, including a box 1 for accommodating the housing cover, the box 1 having a plurality of stacked partition structures 2, each partition structure 2 including a bottom liner 2.1 that can be adapted to the inner wall surface of the housing cover, the bottom surface of the bottom liner 2.1 having a top limiting plate 2.2 that can be adapted to the outer wall surface of the housing cover fixed thereon, and a tolerance space that can be adapted to and limited by the housing cover is formed between two adjacent partition structures 2.

[0031] Specifically, the box 1 is a rectangular box, and the partition structure 2 is a plate structure. The plate surface of the partition structure 2 is parallel to the bottom surface of the box 1. The partition structure 2 is mainly composed of a bottom liner 2.1 and a top limit plate 2.2 in parallel combination. In the normal use state of the partition structure 2, the bottom liner 2.1 is located above the top limit plate 2.2.

[0032] The shell cover has a shell plate portion, and a surrounding edge portion is provided on the circumferential contour of the shell plate portion. One side of the shell plate portion with the surrounding edge portion is the shell opening surface of the shell cover, that is, the location of the inner wall surface of the shell cover, while the other side of the shell plate portion naturally forms the outer wall surface of the shell cover. The bottom liner 2.1 can be adapted to fit the shape and structure of the inner wall surface of the shell cover, and the top limiting plate 2.2 can be adapted to fit the shape and structure of the outer wall surface of the shell cover.

[0033] In practical use, the first partition structure 2 is placed inside the box 1 with the opening of the first shell facing down and the outer wall of the shell facing up, so that the inner wall of the first shell is in contact with the bottom liner 2.1 on the partition structure 2. Then, the second partition structure 2 is stacked on the first partition structure 2. At this time, the top limiting plate 2.2 below the second partition structure 2 is in contact with the outer wall of the first shell. The shell is fully supported and limited between the two adjacent partition structures 2, thereby increasing the contact area with the shell and the number of support points, enhancing the support, effectively reducing the occurrence of shell deformation, and significantly reducing the damage rate of the shell during transportation. Moreover, the structure is simple and easy to implement, and it is particularly suitable for the transportation and packaging of high-value or high-demand automotive parts.

[0034] In another embodiment of the present invention, the partition structure 2 is a hollow plate structure adapted to the box body 1. The top surface of the bottom liner 2.1 is provided with a contour groove 2.3 adapted to the cover opening surface of the shell, and the bottom surface of the top limit plate 2.2 is provided with a recessed groove 2.4 adapted to the outer contour of the shell, thereby increasing the effective contact surface with the shell. The bottom liner 2.1 and the top limit plate 2.2 are both blister boards, and the circumferential contours of the bottom liner 2.1 and the top limit plate 2.2 are both provided with supporting edges 2.5. The space between the bottom liner 2.1 and the top limit plate 2.2 forms a buffer space in the partition structure 2.

[0035] It should be further explained that the partition structure 2 is made of vacuum forming material, and the contour groove 2.3 and recessed groove 2.4 that are adapted to the shell cover are vacuum formed by double-layer vacuum forming equipment. The whole process is simple and easy to implement, and it can improve the fit between the partition structure 2 and the shell cover, and is also conducive to mass production.

[0036] Specifically, after the partition structure 2 is vacuum-formed and cooled, the partition structure 2 takes the form of a box-like structure, which facilitates its placement within the box 1. The supporting edge 2.5 of the bottom liner 2.1 is aligned with the supporting edge 2.5 of the top limit plate 2.2, and they are thermoformed together on the vacuum forming machine to form the circumferential side of the partition structure 2. The contour groove 2.3 is on the top surface of the partition structure 2, and the recessed groove 2.4 is on the bottom surface of the partition structure 2. The space between the bottom liner 2.1 and the top limit plate 2.2 forms a buffer space on the partition structure 2, which also gives the partition structure 2 a certain buffering effect when stacked.

[0037] In another embodiment of the present invention, a plurality of recessed openings 2.6 are provided on the top surface of the bottom liner 2.1, and a plurality of protruding pillars 2.7 are provided on the bottom surface of the top limiting plate 2.2. The recessed openings 2.6 and the protruding pillars 2.7 are vacuum-formed together with the contour groove 2.3 and the recessed groove 2.4 during the vacuum forming process. The recessed openings 2.6 and the contour groove 2.3 are on the bottom liner 2.1, and the protruding pillars 2.7 and the recessed groove 2.4 are on the top limiting plate 2.2.

[0038] In practical use, when multiple partition structures 2 are stacked, the protruding column 2.7 of the upper partition structure 2 can be inserted and matched with the lower recess 2.6, thereby improving the overall stability of the multiple partition structures 2 when stacked, and at the same time enabling the multiple partition structures 2 to play an alignment and positioning role when stacked.

[0039] In another embodiment of the present invention, the box body 1 includes a bottom support plate 1.1, a surrounding plate 1.2, and a box cover 1.3. Both the bottom support plate 1.1 and the box cover 1.3 are double-layered structures formed by vacuum forming. Both the bottom support plate 1.1 and the box cover 1.3 are provided with a tube frame structure 4. The tube frame structure 4 is installed in the sandwich of the double-layered structure of the bottom support plate 1.1 and the box cover 1.3, thereby enhancing the deformation resistance of the bottom support plate 1.1 and the box cover 1.3.

[0040] Furthermore, the box body 1 is provided with a plurality of support rods 3 that can move through the stacked partition structure 2. The two ends of each support rod 3 can be connected to the corresponding tray 1.1 and the tube frame structure 4 on the box cover 1.3. Preferably, the axis of the support rod 3 coincides with the axis of the protruding column 2.7 and the axis of the recess 2.6, and the axis of the support rod 3 is perpendicular to the horizontal plane.

[0041] In actual use, the tube frame structure 4 located inside the cover 1.3, the tube frame structure 4 located inside the pallet 1.1, and the multiple support rods 3 together form a support structure in the box body 1, thereby enhancing the pressure resistance and deformation resistance of the box body 1 in the stacked state, and also protecting the shell inside the box body 1. It should be further noted that the bottom of the bottom pallet 1.1 is provided with multiple support feet, and each support rod 3 can be aligned with the corresponding support foot on the same vertical line, further enhancing the support strength and sharing the pressure on the enclosure 1.2 of the box body 1.

[0042] In another embodiment of the present invention, the pipe rack structure 4 includes a main beam pipe 4.1, through which multiple branch pipes 4.2 are fixedly inserted in the vertical direction of the main beam pipe 4.1. Both the main beam pipe 4.1 and the branch pipes 4.2 are square tubes made of metal. The cross-sections of the main beam pipe 4.1 and the branch pipes 4.2 are rectangular. The centerlines of the main beam pipe 4.1 and the branch pipes 4.2 are parallel to the horizontal plane. The centerline of each branch pipe 4.2 is perpendicular to the centerline of the main beam pipe 4.1. Both ends of each branch pipe 4.2 have through openings 4.3 that are adapted to be inserted into the ends of the support rods 3. Each through opening 4.3 is provided with a locking pin 4.4 that can limit the support rods 3 that extend into the branch pipe 4.2. The locking pin 4.4 can reciprocate along the centerline of the branch pipe 4.2.

[0043] Furthermore, a reinforcing rod 4.5 is rotatably installed inside the main beam tube 4.1 on the box cover 1.3. The reinforcing rod 4.5 has a circular cross-section, and its axis coincides with the axis of the main beam tube 4.1. The reinforcing rod 4.5 moves through each branch tube 4.2 and can rotate axially. The reinforcing rod 4.5 is connected to the locking pin 4.4 via a traction rope 4.6. The end side of the top of the support rod 3 has a half-groove 5 that matches the locking pin 4.4. The half-groove 5 is a straight groove, and its length direction is perpendicular to the length direction of the support rod 3. The locking pin 4.4 can engage with the half-groove 5, thereby restricting the axial movement of the support rod 3. A protruding block 8 is fixed to the end side of the bottom of the support rod 3.

[0044] In actual use, after the layered structure 2 and the shell cover are filled in the box 1, each support rod 3 is inserted through the stacked layered structure 2, so that the bottom end of the support rod 3 is inside the through hole 4.3 on the branch pipe 4.2 on the tray 1.1. At this time, the bottom end of the support rod 3 and the protrusion 8 are both located inside the branch pipe 4.2 on the tray 1.1. Then, the support rod 3 is rotated axially so that the protrusion 8 is displaced from the through hole 4.3. When the support rod 3 is pulled outward, the protrusion 8 contacts the inner top wall of the branch pipe 4.2. Under the restriction of the protrusion 8, the support rod 3 cannot be pulled out from the branch pipe 4.2 on the tray 1.1 through the through hole 4.3, thus completing the initial installation of the support rod 3 on the tray 1.1.

[0045] Then, the box cover 1.3 is placed on top of the enclosure 1.2. At this time, the top of the support rod 3 is inserted into the through-hole 4.3 of the branch pipe 4.2 on the box cover 1.3, so that the half-groove 5 is located inside the branch pipe 4.2. Then, the locking pin 4.4 moves in the forward direction toward the pipe end of the branch pipe 4.2, so that the locking pin 4.4 is engaged in the half-groove 5, thereby limiting the movement of the support rod 3 on the axis.

[0046] It should be further explained that the locking pin 4.4 includes a bar body 4.41. A notch 4.42 is provided on one side of the bar body 4.41, which allows the support rod 3 to pass through vertically. The top surface of the bar body 4.41 is provided with a beveled part 4.43. When the locking pin 4.4 moves forward, the half-groove 5 slides in contact with the beveled part 4.43. The groove wall of the half-groove 5 slides relative to the beveled part 4.43 along the inclined direction of the beveled part 4.43. During the sliding process, the distance between the box cover 1.3 and the bottom support plate 1.1 is further reduced. The protrusion 8 is also pressed more tightly against the inner top wall of the branch pipe 4.2 of the bottom support plate 1.1, making the fixation between the box cover 1.3, the bottom support plate 1.1 and the surrounding plate 1.2 more tight, further strengthening the overall locking firmness, and completing the locking of the box cover 1.3 on top of the surrounding plate 1.2.

[0047] It should be further explained that during the forward movement of the locking pin 4.4, the locking pin 4.4 drives the reinforcing rod 4.5 to rotate in the forward direction via the traction rope 4.6. When the reinforcing rod 4.5 moves in the reverse direction, it pulls on the locking pin 4.4 by winding the traction rope 4.6, thus achieving the reverse movement of the locking pin 4.4. The end of the reinforcing rod 4.5 is equipped with a nut structure that can be matched with a wrench or screw sleeve, allowing the reinforcing rod 4.5 to be rotated axially with the aid of a wrench.

[0048] In another embodiment of the present invention, a fastening rope 6 is provided on the box body 1. One end of the fastening rope 6 is connected to the locking pin strip 4.4 on the box cover 1.3, and the other end of the fastening rope 6 is connected to the pin rod 7. The pin rod 7 can cooperate with the locking pin strip 4.4 of the tube frame structure 4 in the bottom support plate 1.1 to play a load-bearing role.

[0049] In actual use, when the fastening rope 6 is pulled, preferably, the fastening rope 6 is pulled along the axis of the branch pipe 4.2. At this time, the locking pin 4.4 on the box cover 1.3 is pulled and moves in the positive direction, thereby locking the box cover 1.3 on the top of the enclosure 1.2. When the locking of the box cover 1.3 on the top of the enclosure 1.2 reaches the maximum locking limit, the fastening rope 6 can no longer be pulled. At this time, the pin 7 is inserted into the end of the branch pipe 4.2 of the bottom support plate 1.1, so that the bottom side of the pin 7 contacts the inner wall of the branch pipe 4.2, and the upper side of the pin 7 contacts the bottom end of the support rod 3, thereby filling the gap between the support rod 3 and the inner wall of the branch pipe 4.2. In the vertical direction, it works in conjunction with the support rod 3 to play a load-bearing role, which helps to improve the overall support strength of the box 1 when stacked.

[0050] In another embodiment of the present invention, multiple teeth 9 are fixed on the inner wall of the branch pipe 4.2 on the cover 1.3. In actual use, when the fastening rope 6 in the horizontal plane cannot be pulled, the taut fastening rope 6 is moved downward. At this time, the fastening rope 6 engages with the teeth 9, and the teeth 9 penetrate the fastening rope 6, which helps to keep the fastening rope 6 in the branch pipe 4.2 taut and maintain the tightness of the cover 1.3 on the top of the enclosure 1.2. Then, the pin 7 is inserted into the end of the branch pipe 4.2 of the bottom support plate 1.1 to achieve secondary locking. Preferably, the insertion end of the pin 7 has a tapered structure for easy insertion. The rod body of the pin 7 has a bolt sleeve structure that is twisted to fit the end of the reinforcing rod 4.5, which facilitates the axial rotation of the reinforcing rod 4.5. The pin 7 is equivalent to a wrench that can rotate the reinforcing rod 4.5.

[0051] In other words, a support rod 3 is arranged between the box cover 1.3 and the pallet 1.1, and then the support rod 3 is connected and cooperated with the box cover 1.3 and the tube frame structure 4 on the pallet 1.1, thereby improving the overall deformation resistance of the box 1 when stacking, and locally strengthening the deformation resistance of the box cover 1.3 and the pallet 1.1 respectively. It can also lock the box 1 when loading the shell cover. The entire packaging structure assembly is simple, easy to mass produce, and easy to operate and use.

[0052] In another embodiment of the present invention, a plurality of ribs 10 are fixed on the inner wall surface of the partition plate 1.2. Each rib 10 is a straight line and is parallel to the horizontal plane. The parallel ribs 10 form a spacer groove structure. Since the supporting edge 2.5 of the bottom liner plate 2.1 is aligned with the supporting edge 2.5 of the top limit plate 2.2 and is thermoformed on the vacuum forming machine, it forms the circumferential side of the partition structure 2. The edge surface of the supporting edge 2.5 is generally flared outward in the shape of a trumpet. Therefore, the supporting edge 2.5 has a certain outward convex angle on the circumferential side of the partition structure 2.

[0053] In actual use, when the partition structure 2 is subjected to downward pressure, for example, when the cover 1.3 moves toward the support plate 1.1 during the locking process, the partition structure 2 is subjected to downward pressure, causing the partition structure 2 to collapse. This causes the supporting edge 2.5 to protrude outward on the circumferential side of the partition structure 2. The protruding part is engaged with the parallel ribs 10 to form a slot structure, which further improves the integrity between the partition structure 2 and the box body 1, and also provides a certain amount of room for the buffer of the partition structure 2.

[0054] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
