Description

Technical Field

[0001] This invention relates to a multi-layer cargo support mechanism for a material rack, a battery pack transport rack, and a loading method, and is particularly applicable to the warehousing and transportation of power battery packs for new energy vehicles. Background Technology

[0002] In the warehousing and logistics industry, single-layer goods are typically stored using simple support racks or flat racks. Goods are placed directly on the support racks, relying on the rigidity of the racks themselves for stability.

[0003] However, single-layer design leads to low space utilization and cannot meet the high-density storage needs of modern warehousing; goods lack effective fixing measures during handling or transportation, making them prone to sliding or tipping; when multiple goods need to be stored, the lack of a layered positioning structure makes the goods prone to squeezing and colliding with each other, causing damage.

[0004] Therefore, there is a market demand for designing a multi-layer cargo support mechanism, a battery pack transport rack, and a loading method that can store multiple layers of goods and provide stable support. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a multi-layer cargo support mechanism for a material rack.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a multi-layer cargo support mechanism for a material rack, including a mounting chassis, a support top disposed on the mounting chassis, a support frame disposed on the mounting chassis, at least one clamping member with clamping columns disposed on the support frame, and a top pressing member with a top pressing block disposed on the support frame and located above the clamping member. The multi-layer cargo support mechanism for a material rack has a cargo-carrying state. In the cargo-carrying state, the top pressing block and at least one clamping column are distributed sequentially from top to bottom directly above the support top, and a positioning space for clamping cargo is formed between each pair of upper and lower components.

[0007] In some embodiments, the clamping member is rotatably or slidably mounted on the support frame, and a clamping locking mechanism is provided between the clamping member and the support frame to position the clamping member in a loaded state.

[0008] In some embodiments, the support frame includes a support main rod and a locking sleeve fixed to the support main rod. The clamping member further includes a clamping rotating sleeve that can both rotate and slide on the support main rod, and a clamping connecting rod fixed between the clamping column and the clamping rotating sleeve. The clamping locking mechanism includes an annular groove disposed between the locking sleeve and the support main rod, and a cargo-carrying lock groove with an upward opening on the locking sleeve. When the multi-layer cargo support mechanism of the material rack is positioned in the cargo-carrying state, the clamping rotating sleeve is located in the annular groove, and the clamping connecting rod falls into the cargo-carrying lock groove.

[0009] In some embodiments, the top pressure member is rotatably or slidably mounted on the support frame, and a top pressure locking mechanism is provided between the top pressure member and the support frame to position the top pressure member in a loaded state.

[0010] In some embodiments, the support frame further includes a support base tube fixed to the mounting chassis at the bottom, the support main rod being rotatably or slidably mounted on the support base tube, and a positioning structure is provided between the support main rod and the support base tube to position the support main rod in a standing state.

[0011] In some embodiments, the positioning structure includes a sliding groove formed on the support base tube and a locking groove extending spirally downward from the bottom of the sliding groove. The lower end of the support main rod has a rotating guide pin. The support main rod is slidably inserted into the support base tube. The rotating guide pin is slidably disposed in the sliding groove and the locking groove. The support base tube has a folding notch. When the support main rod is in the folded position, the rotating guide pin is located at the upper end of the sliding groove, and the support main rod is inverted in the folding notch. When the support main rod is in the standing position, the rotating guide pin is located at the bottom of the locking groove.

[0012] In some embodiments, at least one of the two ends of the clamping column has a protruding clamping positioning protrusion that can be inserted into the cargo opening, and the upper end of the support top has a support top positioning protrusion that can be inserted into the cargo opening. When the multi-layer cargo support mechanism of the rack is in a loaded state, the clamping positioning protrusion and the support top positioning protrusion are in the same straight direction.

[0013] In some embodiments, the outer edge of at least one end of the clamping column extends outward in the vertical direction to form a clamping stop. When the multi-layer cargo support mechanism of the rack is positioned in the loaded state, the clamping stop is positioned on the outside of the corresponding positioning space.

[0014] Another technical problem to be solved by the present invention is to provide a battery pack transport rack.

[0015] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a battery pack transport rack, including the multi-layer cargo support mechanism of the rack as described in any of the above embodiments, wherein the battery pack transport rack includes a base frame, and the multi-layer cargo support mechanism of the rack has multiple components, which are respectively installed on the periphery of the base frame via the mounting chassis.

[0016] Another technical problem to be solved by the present invention is to provide a battery packing method.

[0017] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a multi-layer cargo loading method, using the above-mentioned battery pack transport rack, comprising the following specific steps: Step 1: Move the clamping column and top pressure block away from directly above the support top; Step 2: Place the Nth battery pack on top of all the supports, initially N=1, i.e., the first loading of the battery pack; Step 3: Move the Nth clamping post from bottom to top to the upper surface of the Nth battery pack, and position it directly above the corresponding support top, thus clamping and positioning the Nth battery pack vertically. If there is an (N+1)th clamping post, place the (N+1)th layer of battery pack on the Nth clamping post and repeat this step; if there are no more clamping posts, proceed to step 4. Step 4: Place the last battery pack on all N+1 clamping posts, move the top pressure block to the top surface of the last battery pack, and ensure that all clamping posts and top pressure blocks are directly above the support top. Clamp and position all battery packs from top to bottom to complete the multi-layer battery pack loading.

[0018] The scope of this invention is not limited to technical solutions formed by specific combinations of the above-described technical features, but also includes other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in this application.

[0019] Due to the application of the above technical solutions, the present invention has the following advantages compared with the prior art: The present invention provides a multi-layer cargo support mechanism for a rack, a battery pack transport rack and a loading method. By setting a support top, a support frame, a clamping member with clamping columns and a pressing member with pressing blocks, the rack can form a multi-layer positioning space, which significantly improves the utilization rate of storage space. The cooperative design of the pressing blocks and clamping columns realizes the accurate positioning and reliable clamping of multi-layer cargo, effectively preventing the displacement and tipping of cargo during the handling process, and greatly improving the flexibility and safety of warehousing operations.

[0021] like Figure 3 The battery pack transport rack includes a base frame 6 and multiple multi-layer cargo support mechanisms, which are respectively set around the base frame 6. They can be flexibly installed in different positions on the base frame according to actual needs, and can be adapted to various battery packs of different lengths and widths to meet the fixing requirements of various battery packs.

[0022] like Figure 1 , 2 The multi-layer cargo support mechanism shown includes a mounting base 1, a support top 2 disposed on the mounting base 1, a support frame 3 disposed on the mounting base 1, two clamping members 4 disposed on the support frame 3 that can both rotate and slide, and a top pressing member 5 rotatably disposed on the support frame 3 and located above the clamping members 4.

[0023] The clamping component 4 includes a clamping post 41, a clamping rotating sleeve 42 that can both rotate and slide and is sleeved on the supporting main rod 31, and a clamping connecting rod 43 fixed between the clamping post 41 and the clamping rotating sleeve 42.

[0024] The top pressing component 5 includes a top pressing block 51, a top pressing rotating sleeve that can only be rotatably mounted on the support frame 3, and a top pressing connecting rod fixed between the top pressing block 51 and the top pressing rotating sleeve.

[0025] The multi-layer cargo support mechanism of the rack has a cargo-carrying state. In this cargo-carrying state, the top pressing block 51 and at least one clamping column 41 are distributed from top to bottom directly above the support top 2, and a positioning space for clamping cargo is formed between each pair of upper and lower components.

[0026] A clamping locking mechanism is provided between the clamping member 4 and the support frame 3 to position the clamping member 4 in the loaded state. A pressing locking mechanism is provided between the pressing member 5 and the support frame 3 to position the pressing member 5 in the loaded state.

[0027] The support frame 3 includes a support main rod 31 and a locking sleeve 32 sleeved and fixed on the support main rod 31. The clamping and locking mechanism includes an annular groove between the locking sleeve 32 and the support main rod 31 and a cargo loading lock groove 321 with an upward opening on the locking sleeve 32. When the multi-layer cargo support mechanism of the material rack is positioned in the cargo loading state, the clamping rotating sleeve 42 is located in the annular groove, and the clamping connecting rod 43 falls into the cargo loading lock groove 321.

[0028] In this embodiment, the locking sleeve 32 is also provided with a clearance groove. When the goods need to be removed, the clamping link 43 needs to be moved away. In this embodiment, it is moved into the clearance groove, and the clamping column 41 is offset from the top of the support, which can effectively prevent the clamping column 41 from shaking and rubbing against the goods when unloading.

[0029] A cargo lock seat is fixed on the support frame 3, and a top-pressing locking mechanism is located between the cargo lock seat and the top-pressing connecting rod. Specifically, the support frame 3 has a cargo positioning hole, and the top-pressing component 5 also includes a spring pin seat fixed on the top-pressing rotating sleeve and a positioning spring pin slidably disposed on the spring pin seat. An elastic element is provided between the positioning spring pin and the spring pin seat to move the positioning spring pin toward the center of the support frame 3. When the top-pressing component 5 rotates to the cargo-loading state, the positioning spring pin springs into the cargo positioning hole.

[0030] The support frame 3 also includes a support base tube 33 located at the bottom and fixed to the mounting chassis 1. The support main rod 31 is rotatably or slidably mounted on the support base tube 33, and a positioning structure is provided between the support main rod 31 and the support base tube 33 to position the support main rod 31 in a standing state.

[0031] The positioning structure includes a sliding groove 331 formed on the support base tube 33 and a locking groove 332 extending spirally downward from the bottom of the sliding groove 331. The lower end of the support main rod 31 has a rotating guide pin 311. The support main rod 31 is slidably inserted into the support base tube 33. The rotating guide pin 311 is slidably set in the sliding groove 331 and the locking groove 332. The support base tube 33 has a folding notch 333. When the support main rod 31 is in the folded position, the rotating guide pin 311 is located at the upper end of the sliding groove 331 and the support main rod 31 is inverted in the folding notch 333. When the support main rod 31 is in the standing position, the rotating guide pin 311 is located at the bottom of the locking groove 332.

[0032] like Figure 5As shown, the clamping column 41 has clamping and positioning protrusions 411 at both ends that can be inserted into the corresponding openings around the battery pack. The diameter of the clamping and positioning protrusions 411 is 0.5-1mm smaller than the openings of the battery pack. The upper end of the support top 2 has a support top positioning protrusion 21 that can be inserted into the cargo opening of the battery pack. When the multi-layer cargo support mechanism of the rack is in the loaded state, the clamping and positioning protrusions 411 and the support top positioning protrusions 21 are in the same straight direction.

[0033] Clamping stops 412 extend upward and downward from the outer edges of both ends of the clamping posts 41, respectively. The inner side of the clamping stops 412 is sloping. During loading, the upper clamping stops 412 on the surrounding clamping posts 41 act as guides, guiding the battery pack towards the center of the rack, facilitating the insertion of the clamping positioning protrusions 411 into the openings on the corresponding edges of the goods. When the multi-layer goods support mechanism of the rack is positioned in the loaded state, the clamping stops 412 are positioned on the outside of the corresponding positioning space, serving as an auxiliary positioning function.

[0034] The battery pack loading method of the battery pack transport rack described above, taking three battery pack layers as an example, is configured with two clamping columns and includes the following specific steps: Step 1: Move the clamping column 41 and the top pressing block 51 away from the top of the support 2, and the clamping connecting rod 43 falls into the clearance groove of the locking sleeve 32. The top pressing block 51 rotates and moves away.

[0035] Step 2, initial battery pack loading: Place the first battery pack on all the support tops 2, and position the openings around the first battery pack on the corresponding support top positioning protrusions 21 of the support tops 2.

[0036] Step 3: From bottom to top, first move the first clamping post 41 to the upper surface of the first battery pack and position it directly above the corresponding support top 2 to clamp and position the first battery pack. Then place the second battery pack on the first clamping post 41 and move the second clamping post 41 to the upper surface of the second battery pack and position it directly above the corresponding first clamping post 41.

[0037] In detail, the clamping link 43 of the first clamping member 4 is moved upward from the clearance groove and then rotated at a certain angle to fall into the cargo lock groove 321. The clamping positioning protrusion 411 at the lower end of the first clamping post 41 is inserted into the opening of the first battery pack, and the clamping positioning protrusion 411 and the support top positioning protrusion 21 are set to abut against each other. Then, the second battery pack is placed on the upper surface of the first clamping post 41, and its opening is fitted onto the clamping positioning protrusion 411 at the upper end of the first clamping post 41. The clamping link 43 of the second clamping member 4 is moved upward from the clearance groove and rotated at a certain angle to fall into the corresponding cargo lock groove 321. The clamping positioning protrusion 411 at the lower end of the second clamping post 41 is inserted into the opening of the second battery pack, and the clamping positioning protrusions 411 of the first clamping post and the second clamping post are set to abut against each other. Among them, the two upper and lower clamping and positioning protrusions 411 that are set in opposition, and the clamping and positioning protrusions 411 and the supporting top positioning protrusion 21 that are set in opposition, are key structures for achieving stable loading and transportation of multi-layer battery packs. They are positioned in the horizontal direction and also prevent inter-layer displacement caused by bumps during transportation / handling.

[0038] Step 4: Place the third battery pack, i.e., the last battery pack, on all the second clamping posts 41. Place the third battery pack on the upper surface of the second clamping posts 41, with its opening fitted onto the clamping positioning protrusion 411 at the upper end of the second clamping posts 41. Move the top pressure block 51 to the upper surface of the top battery pack, and the positioning spring pin pops into the loading positioning hole. Lock the top pressure connecting rod of the top pressure member 5 to the support frame 3 with screws to ensure that all clamping posts 41 and top pressure blocks 51 are located directly above the support top 2. Clamp and position all battery packs from top to bottom, completing the multi-layer battery pack loading. That is, if the battery pack is to be loaded in two layers, each multi-layer cargo support mechanism of the rack needs one clamping post; if the battery pack is to be loaded in three layers, each multi-layer cargo support mechanism of the rack needs two clamping posts. When loading M layers of cargo, the required number of clamping posts is M-1.

[0039] The above are the loading steps for the battery pack. After the transport rack is in place, the goods need to be unloaded. The specific steps include: Step 1: Remove the top pressure block 51 from the top surface of the top battery pack, so that it is completely offset from the top of the support 2, and remove the top battery pack.

[0040] Step 2: Move the upper clamping post 41 away from directly above the support top 2; remove the middle battery pack; move the next layer clamping post 41 away from directly above the support top 2, and repeat the operation until all battery packs are removed.

[0041] Step 3: Move the top pressing member 5 and the clamping member 4 to their loading positions, push the rotating guide pin 311, which falls in the locking groove 332, upward to the top of the sliding groove 331, and rotate and fold the support frame 3 inward around the rotating guide pin 311 until it is as shown. Figure 4 Fold at the indicated position.

They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
