Description

Technical Field

[0001] This utility model belongs to the field of parts packaging technology and relates to a storage and transportation device for a clutch housing. Background Technology

[0002] The clutch housing is a critical component of the gearbox assembly, providing the mounting base and operating space for the clutch and related components. It works closely with other gearbox parts, and its precision and quality directly affect the gearbox's performance, reliability, and lifespan. If it is damaged or cracked during logistics and transportation, it can lead to unstable power transmission, abnormal noises, or even transmission system failures, seriously impacting vehicle safety.

[0003] Typically, the production, supply, and assembly of clutch housing parts are scattered across different regions, making long-distance logistics and transportation commonplace. During this process, the parts undergo multiple loading, unloading, handling, and transportation operations. During loading and unloading, differences in operator skills, improper equipment use, or lack of protection can easily cause parts to be bumped or dropped. During handling, unsuitable tools or incorrect methods can lead to friction and collisions. During transportation, vehicle bumps, vibrations, and emergency braking cause relative movement of the parts within the container, increasing the risk of impacts. Therefore, protective packaging is necessary for clutch housing parts.

[0004] Existing packaging methods mainly include paper packaging, wooden packaging, and simple plastic packaging. While paper packaging offers cushioning and is low-cost, its load-bearing and impact resistance are limited, making it prone to damage during transport. It is also sensitive to humidity, significantly reducing its protective effect. Wooden packaging offers acceptable strength and load-bearing capacity, but it is heavy, expensive, consumes large amounts of timber, does not meet environmental protection requirements, and is susceptible to insect infestation and decay. Simple plastic packaging is unaffected by humidity and insects, has good corrosion resistance and some impact resistance, but its flexibility and cushioning are insufficient. It cannot adequately support and secure complex-shaped and heavy clutch housing parts, failing to restrict their movement. Furthermore, simple plastic packaging lacks targeted design; to ensure structural stability, the packaging thickness is usually increased, leading to greater weight. Simple plastic packaging does not fully consider the shape, size, weight, and transportation environment of the parts, and cannot accurately limit and fix them according to their characteristics. It cannot meet the requirements for stable, secure, and bump-free transport, resulting in numerous quality risks for parts during long-distance logistics transport. Utility Model Content

[0005] The purpose of this utility model is to provide a storage and transportation device for clutch housings, so as to solve the technical problems that simple plastic packaging of clutch housing parts is heavy, lacks specificity, and cannot be accurately limited and fixed according to the characteristics of the parts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: This utility model provides a storage and transportation device for a clutch housing, comprising several layers of stacked blister trays, wherein each side of the blister tray has at least one large end receiving cavity and at least one small end receiving cavity for a part. On both sides of the blister tray, the large end receiving cavity and the small end receiving cavity are arranged back to back; The large end receiving cavity and the small end receiving cavity of the part in the two adjacent layers of the blister tray face each other and form a part receiving space. The small end receiving cavity of the part is provided with a limiting protrusion, which can be embedded into the recessed area of ​​the clutch housing part.

[0007] Furthermore, when there are more than two large-end accommodating cavities and two small-end accommodating cavities on the same side of the blister tray, the large-end accommodating cavities and the small-end accommodating cavities are arranged alternately.

[0008] Furthermore, it also includes a chassis and a blister cover, with several layers of the blister trays located between the chassis and the blister cover. The periphery of the blister trays is provided with a raised flange facing the chassis. The chassis is embedded inside the flange and in contact with the blister trays. The flanges are provided with a first reinforcing rib.

[0009] Furthermore, the chassis is provided with two support legs, which are located on the side of the chassis away from the blister tray; The blister cover is provided with a limiting part, which is located on the side of the blister cover away from the blister tray; When the chassis is stacked on the blister cover, the limiting part is used to restrict the legs from sliding on the blister tray.

[0010] Furthermore, the legs are straight parallelepipeds, and the legs are arranged in parallel. The limiting part consists of four L-shaped limiting plates, which are located at the four apex corners of the same rectangle. When the chassis is stacked on the blister cover, the support leg is located between the two L-shaped limiting plates.

[0011] Furthermore, the limiting part also includes several protrusions, with at least two protrusions arranged between two adjacent L-shaped limiting plates, and a strap groove formed between the L-shaped limiting plate and the protrusions.

[0012] Furthermore, the blister cover has cavities arranged in a grid pattern, and the cavities are located on the side of the blister cover close to the blister tray. Reinforcing tubes are embedded in the cavities.

[0013] Furthermore, the blister tray is provided with several drainage holes.

[0014] Furthermore, both the large end cavity and the small end cavity of the part are stepped cavities; Both the large end cavity and the small end cavity of the part are provided with several second reinforcing ribs.

[0015] Furthermore, the large end receiving cavity of the part is provided with several claws around its periphery. The large end receiving cavity of the part is used to place the open end of the clutch housing part, and the claws are used to limit the opening end of the clutch housing part. The limiting protrusion includes a central limiting protrusion and / or two edge limiting protrusions. The central limiting protrusion is located at the center of the small end receiving cavity of the part, and the two edge limiting protrusions are equidistant from the central limiting protrusion.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This utility model utilizes multi-layer stacking to fully utilize vertical space, facilitating centralized management and handling, and improving the efficiency of logistics operations. On both sides of the blister tray, the large-end receiving cavities of the parts are arranged back-to-back, as are the small-end receiving cavities. After the clutch housing parts are packaged and stacked, the large-port ends of the upper and lower layers of clutch housing parts are aligned, and the closed ends are opposite each other, applying vertical pressure to the clutch housing parts and improving the overall load-bearing capacity of the storage and transportation device. Because the open end of the clutch housing part is larger and the closed end is smaller, placing adjacent parts in opposite directions balances the overall center of gravity of the packaging, making it more stable during transportation, and also improves the utilization rate of packaging space and reduces the overall weight of the blister tray. The limiting protrusions can be embedded into the recessed areas of the clutch housing parts, achieving precise positioning and fixation of the parts. This utility model's multi-layer stackable blister tray improves space utilization and logistics efficiency. Adjacent parts storage spaces are also arranged in opposite directions, further enhancing space utilization. The back-to-back storage cavities and the facing parts storage spaces provide a stable and independent storage environment for the parts, effectively isolating and protecting them. Limiting protrusions achieve precise positioning and fixation of the parts, further reducing the risk of bumps and damage during long-distance logistics transfers caused by loading, unloading, handling, and transportation. This utility model can meet the requirements for smooth, secure, and bump-free transfer of clutch housing parts. Attached Figure Description

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0020] It should be noted that the terms "first," "second," etc., in the specification and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings: Example 1: See Figure 1This utility model discloses a storage and transportation device for a clutch housing, including several layers of stacked blister trays 2. The multi-layer stacking fully utilizes vertical space, increasing the number of parts that can be stored within a limited floor area, which is beneficial for improving space utilization in transportation and storage, and reducing logistics costs. At the same time, the stacking structure is relatively stable, facilitating centralized management and handling, and improving the efficiency of logistics operations.

[0022] See Figures 2 to 5 The blister tray 2 has several large-end receiving cavities 201 and several small-end receiving cavities 202 on both sides to achieve multi-layer stacking capability.

[0023] See Figures 2 to 5 When there are more than two large-end receiving cavities 201 and small-end receiving cavities 202 on the same side of the blister tray 2, the large-end receiving cavities 201 and small-end receiving cavities 202 are arranged in an alternating manner, which is beneficial to make full use of the space of the blister tray 2.

[0024] See Figures 2 to 5 On both sides of the blister tray 2, the large end receiving cavity 201 and the small end receiving cavity 202 of the part are arranged back to back. After the clutch housing parts 4 are packaged and stacked, the large ends of the upper and lower clutch housing parts 4 are aligned, and the closed ends of the upper and lower clutch housing parts 4 are opposite each other. This allows vertical pressure to be applied to the clutch housing parts 4, which helps to improve the overall load-bearing capacity of the storage and transportation device.

[0025] The large-end receiving cavity 201 and the small-end receiving cavity 202 of the two adjacent layers of the blister tray 2 face each other and form a receiving space for the parts. Because the large-end receiving cavity 201 and the small-end receiving cavity 202 are arranged in an alternating manner, the adjacent receiving spaces for the parts are also arranged in opposite directions, which optimizes the placement of parts within a limited space. Since the open end of the clutch housing part 4 is larger and the closed end is smaller, the opposite arrangement of adjacent parts helps to balance the overall center of gravity of the packaging, making the packaging more stable during transportation. It also improves the utilization rate of the packaging space and reduces the overall weight of the blister tray 2.

[0026] See Figures 2 to 5The small end receiving cavity 202 of the part is provided with a limiting protrusion 203, which can be embedded into the recessed area of ​​the clutch housing part 4. The limiting protrusion 203 can be embedded into the recessed area of ​​the clutch housing part, achieving precise limiting and fixing of the part. It can effectively limit the range of movement of the part within the part receiving space, preventing the part from shifting, shaking, or rotating during transportation, further enhancing the protective effect of the packaging on the part, and improving the stability and reliability of part transfer.

[0027] See Figure 1 In this embodiment of the invention, a base 1 and a blister cover 3 are also included. Several layers of blister trays 2 are located between the base 1 and the blister cover 3. The periphery of each blister tray 2 has a raised flange 208 facing the base 1. The base 1 is embedded inside the flange 208 and in contact with the blister tray 2. The flange 208 is provided with a first reinforcing rib 210. The blister trays 2, together with the base 1 and the blister cover 3, further enhance the stacking capacity of the device. During transport, adjacent blister trays 2 may collide and rub against each other. The first reinforcing rib 210 enhances the structural strength of the flange 208 and prevents the flange 208 from being damaged due to collision.

[0028] See Figure 1 In this embodiment of the present invention, the chassis 1 is provided with two support legs 101, and the support legs 101 are located on the side of the chassis 1 away from the blister tray 2; The blister cover 3 is provided with a limiting part 301, which is located on the side of the blister cover 3 away from the blister tray 2; When the chassis 1 is stacked on the blister cover 3, that is, when the storage and transportation device is stacked in multiple layers, the limiting part 301 is used to restrict the support leg 101 from sliding on the blister tray 2, which is beneficial to realize multi-layer stacking.

[0029] In this embodiment of the utility model, the support leg 101 is a right parallelepiped, and the support legs 101 are arranged in parallel. The limiting part 301 consists of four L-shaped limiting plates, which are located at the four apex corners of the same rectangle. When the chassis 1 is stacked on the blister cover 3, that is, when the storage and transportation device is stacked in multiple layers, the support leg 101 is located between the two L-shaped limiting plates.

[0030] See Figure 1In this embodiment of the invention, the limiting part 301 further includes several protrusions 302. At least two protrusions 302 are arranged between two adjacent L-shaped limiting plates. The protrusions 302, in conjunction with the auxiliary L-shaped limiting plates, limit the support leg 101. Simultaneously, a strapping groove 303 is formed between the L-shaped limiting plate and the protrusions 302. After the storage and transportation device is stacked in multiple layers, the multiple layers are secured using straps combined with the strapping groove 303, which helps improve the stability of the stacking.

[0031] See Figure 1 In this embodiment of the utility model, the support leg 101 has a hollowed-out shape, which is beneficial to the lightweighting of the overall structure.

[0032] See Figure 7 In this embodiment of the invention, the blister cover 3 has cavities 304 arranged in a grid pattern. The cavities 304 are located on the side of the blister cover 3 closest to the blister tray 2, and reinforcing tubes are embedded within each cavity 304. The grid-shaped arrangement of the cavities 304 with embedded reinforcing tubes enhances the load-bearing capacity of the blister cover 3 and ensures stacking stability.

[0033] See Figure 5 and Figure 6 In this embodiment of the utility model, the chassis 1, the blister tray 2 and the blister cover 3 are all provided with a plurality of drainage holes 204 to prevent water from accumulating inside the blister tray.

[0034] See Figures 2 to 5 In this embodiment of the present invention, both the large end receiving cavity 201 and the small end receiving cavity 202 of the part are stepped cavities. The stepped cavities are used to adapt to different models of clutch housing parts 4. For smaller clutch housing parts 4, the inner step is used for limiting the size, and for larger clutch housing parts 4, the outer step is used for limiting the size.

[0035] See Figure 4 Both the large end receiving cavity 201 and the small end receiving cavity 202 of the part are provided with a plurality of second reinforcing ribs 209. On the one hand, the second reinforcing ribs 209 help to improve the structural strength; on the other hand, the second reinforcing ribs 209 reduce the contact area between the clutch housing part 4 and the receiving cavity, and prevent metal debris from wearing down the clutch housing part 4 between the blister tray 2 and the clutch housing part 4.

[0036] See Figure 2 In this embodiment of the present invention, the periphery of the large end receiving cavity 201 of the part is provided with a plurality of claws 205. The large end receiving cavity 201 of the part is used to place the open end of the clutch housing part 4, and the claws 205 are used to limit the opening end of the clutch housing part 4. See Figure 4 The limiting protrusion 203 includes a central limiting protrusion 206 and two edge limiting protrusions 207. The central limiting protrusion 206 is located at the center of the small end receiving cavity 202 of the part, and the two edge limiting protrusions 207 are equidistant from the central limiting protrusion 206.

[0037] This utility model's multi-layer stackable blister tray 2 improves space utilization and logistics efficiency; adjacent parts storage spaces are also arranged in opposite directions, further enhancing space utilization; the back-to-back storage cavities and the directly opposite parts storage spaces provide a stable and independent storage environment for the parts, effectively isolating and protecting them; the limiting protrusion 203 achieves precise limiting and fixing of the parts, further reducing the risk of bumps and damage to the parts during long-distance logistics transfer due to loading, unloading, handling, and transportation. This utility model can meet the requirements for smooth, secure, and bump-free transfer of clutch housing parts 4. Furthermore, compared to existing paper packaging, wooden packaging, and simple plastic packaging, this storage and transportation device may have greater advantages in terms of cost, environmental friendliness, versatility, and adaptability.

[0038] Example 2: See Figure 2 This embodiment discloses a storage and transportation device for a clutch housing. Unlike the above embodiments, the limiting protrusion 203 in this embodiment includes a central limiting protrusion 206, which is located at the center of the small end receiving cavity 202 of the part.

[0039] Example 3: See Figure 3 This embodiment discloses a storage and transportation device for a clutch housing. Unlike the above embodiments, the limiting protrusion 203 in this embodiment includes two edge limiting protrusions 207, and the distances from the two edge limiting protrusions 207 to the center of the small end receiving cavity 202 of the part are equal.

[0040] Example 4: See Figures 1 to 7 This embodiment discloses a storage and transportation device for clutch housings. For clutch housing parts, which are an important component of the gearbox assembly, there are potential risks such as bumps and knocks during long-distance logistics transportation. Two types of blister trays 2 with different capacity and a blister cover 3 are designed to meet the storage, transportation and stacking needs of clutch housing parts of different sizes within the factory area or between regions.

[0041] In use, the blister tray 2 and blister cover 3 can be used with the chassis 1. In this embodiment, the chassis 1 is an iron tray.

[0042] During transport, a standard iron pallet serves as the base, and the blister pallet 2 has downward-facing flanges 208 around its perimeter covering the upper surface of the iron pallet to prevent it from sliding during transport. To improve logistics efficiency, a blister cover 3 is designed to enable two-layer stacking of the entire pallet. L-shaped limiting plates are added to the four corners of the upper surface of the blister cover 3 to restrict the sliding of the support legs 101 under the upper iron pallet. A grid-shaped cavity 304 is added inside the blister cover 3 to increase structural strength and meet the load-bearing requirements for long-distance transport. In this embodiment, a steel pipe is embedded in the grid-shaped cavity 304.

[0043] This invention is compatible with 24 types of clutch housings, as detailed below: This utility model designs two types of blister trays 2, which are divided into four-compartment blister trays and three-compartment blister trays according to the number of compartments they can hold. See [link / reference] Figures 2 to 4 The four-compartment vacuum forming system includes four compartments for accommodating parts. See details. Figure 5 The three-compartment vacuum forming system includes three spacers for accommodating different parts. The four-compartment system can accommodate sixteen types of clutch housing parts, while the three-compartment system can accommodate eight types. The stepped cavities are designed according to the external dimensions of different parts. At the same time, for parts with the same structural features, such as through holes or the same points of the mating surface projection, corresponding bosses 302 are added for limiting, so as to meet the compatibility requirements of different parts. The sliding range of each part within the vacuum forming tray 2 is less than 10mm.

[0044] The blister tray 2 has a first reinforcing rib 210 around its perimeter and a strap groove 303.

[0045] To prevent collisions between the blister tray 2 and the flange 208 of the blister tray 2 during loading, which could cause damage to the four sides, the flange structure is reinforced by closely arranged first reinforcing ribs 210, thereby improving the service life of the blister tray. This utility model of blister tray can be stacked and used for the storage and transfer of shell parts within or between factories.

[0046] Example 5: See Figures 1 to 7 This embodiment discloses a storage and transportation device for a clutch housing. The overall size of the blister tray 2 is 1150mm×1150mm×90mm. When in use, it is placed on a standard iron tray of 1100mm×1100mm. Then, the clutch housing parts 4 and the blister tray 2 are stacked in sequence. Before reaching the standard height of 1.35 meters, the blister cover 3 is used to seal and pack it.

[0047] To improve the space utilization of the blister tray 2, the clutch housing part 4 is placed in both directions inside the blister, sitting on the cavity and boss limiter formed by the suction on the upper surface of the blister tray, in order to limit the range of movement of the part, increase the stability of stacking and transportation, and at the same time accommodate the needs of multiple types of parts.

[0048] When stacking clutch housing parts in four layers, a forward and reverse stacking method is adopted. Cavity limits are designed based on the placement method to fully utilize the part's shape and maximize its load-bearing capacity. The load on the blister tray is reduced and evenly distributed to avoid localized stress and deformation, thus extending the tray's lifespan. The blister tray itself uses 8mm thick raw material, resulting in a thickness greater than 4mm after molding, and a load-bearing capacity greater than 400kg, meeting the needs of most working conditions.

[0049] The blister cover 3 measures 1200mm × 1200mm × 90mm. In use, it covers the top blister tray 2. L-shaped supports at the four corners help to support the iron tray and limit its position. Internally, it contains 40mm × 40mm × 2mm stainless steel tubing arranged in a grid pattern to increase load-bearing capacity and transfer the weight of the upper layer to the lower clutch housing part 4. The grid pattern also provides stability, ensuring overall stability and safety when stacked.

[0050] After the entire stack is completed, it is packaged. The upper surface of the blister cover 3 has pre-drilled grooves 303 for the strapping straps in a grid pattern, with a depth of 3mm, to prevent the strapping straps from loosening or breaking due to compression during pallet stacking. The blister tray has reinforcing ribs with concave and convex shapes around its perimeter to enhance its impact resistance, increase structural strength, prevent damage to the blister pack caused by impacts during disassembly and transportation, and improve the service life of the blister pack.

[0051] The above content is only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed in this utility model shall fall within the scope of protection of this utility model.
