Description

Technical Field

[0001] The present invention relates to the technical field of cargo carts, and in particular to a dynamic foldable space-optimized cargo cart system. Background Art

[0002] With the diversification of logistics, warehousing, and household transport needs, traditional carts are no longer able to meet modern users' demands for efficient transport in terms of space utilization, scenario adaptability, and ease of operation. While existing cart designs have been optimized for specific scenarios, they generally lack versatility.

[0003] In the prior art, CN115844550A discloses a cargo cart for emergency care, the core structure of which includes a cart body, a guide body, and an instrument stabilization assembly. The cart is designed with a triangular guide body, which makes it easy to break through the crowd in an emergency care environment. At the same time, the buffer space composed of an elastic diaphragm and a pump air assembly effectively prevents the equipment from tipping over during travel, thereby achieving specific functional optimization in emergency scenarios. However, this technical solution mainly focuses on the vertical requirements for fixing equipment in the medical field. Its technical principles and structural design do not involve broader universal issues such as dynamic adjustment of the cargo space, folding and storage, and multi-scene adaptation, and are essentially different from the application scenarios of the present invention.

[0004] Furthermore, while some foldable cart designs exist in the prior art, such as the lamp cup carrying cart disclosed in CN108297908B, a foldable shopping cart that utilizes a cross-bar structure to achieve a foldable frame, these carts still have a fixed single-layer loading platform that cannot be dynamically adjusted based on the actual size and quantity of the goods, making it difficult to accommodate the stacking needs of goods of varying sizes.

[0005] And there are the following problems: 1. Low space utilization: Traditional carts often utilize fixed structures, resulting in limited loading area. When transporting too many items, they are prone to falling due to unstable stacking. Furthermore, they cannot dynamically adjust the number of loading layers or lateral support area based on the size of the goods. For example, transporting long items such as furniture and panels requires additional fixings or multiple handling steps, significantly reducing handling efficiency.

[0006] 2. Poor storage and portability: Traditional strollers are bulky and lack quick-folding features, making them difficult to compact after use. Carrying and storing strollers are a major pain point for users, especially at home or outdoors. While some foldable strollers can fold to a certain degree, they require manual disassembly of multiple parts, making the process complex and time-consuming.

[0007] 3. Inadequate adaptability: Different scenarios (e.g., shopping malls, warehouses, homes, and outdoor environments) place significant differences in the requirements for cart load capacity, stability, anti-slip properties, and terrain maneuverability. Traditional carts have limited functionality and lack modularity, making it difficult to adapt components (e.g., wheel types) to complex terrains (e.g., sand, grass, and stairs).

[0008] 4. Lack of safety and intelligence: Traditional carts lack effective cargo securing devices (such as anti-slip mats and straps) and anti-slip features, making them prone to sliding or tipping over on slopes or uneven surfaces, threatening the safety of both users and cargo. Furthermore, carts rely on manual folding and unfolding, lacking intelligent features like load monitoring and automatic braking, limiting the user experience.

[0009] In summary, achieving efficient use of cargo space, rapid form conversion, and multi-scenario adaptation through structural innovation has become a pressing technical challenge in this field. This invention addresses this need by proposing a dynamically foldable, space-optimizing cargo cart system, aiming to meet modern users' demands for efficient transport while enhancing the cart's versatility and user experience. Summary of the Invention

[0010] The technical problem to be solved by the present invention is to provide a dynamic foldable space-optimized cargo cart system to solve the problems existing in the technical field of cargo carts, such as low space utilization, inconvenient storage, poor scene adaptability, lack of effective cargo fixing devices and anti-slip design, complex folding and unfolding processes and lack of intelligent functions, and overcome the limitations of traditional carts in the fields of cargo cart technology, such as limited cargo area, low handling efficiency, large space occupation, single function and poor user experience.

[0011] To achieve the above-mentioned purpose, the present invention adopts the following technical solutions: Specifically, a dynamic foldable space-optimized cargo cart system of the present invention includes a body, which is arranged as an integral frame structure, covering a frame and a skeleton, a control frame is detachably and slidably mounted on the skeleton, a storage component is mounted above the frame for carrying items, and universal wheels are detachably mounted below, which can rotate freely to achieve flexible movement of the cart.

[0012] The cart's frame is equipped with a set of connecting axle seats, which are fitted with bottom wheels. The connecting sleeves of the bottom wheels connect the connecting axle seats to the frame, ensuring the stability of the cart's structure. The frame is equipped with connecting seats, which are hinged to the connecting seats on the frame via pins, enabling a flexible connection between the frame and the bottom wheels. The bottom wheels include connecting sleeves that are rotatably mounted to the connecting axle seats. These connecting sleeves are mounted with wheel seats, which are rotatably mounted with a set of pulleys, enhancing the cart's mobility.

[0013] The control frame and auxiliary components: The control frame consists of a slide mounted on a frame. The slide fits over the frame and can slide along the frame for adjustment. A support rod is inserted above the slide, on which a tow bar and auxiliary components slide. The auxiliary components are installed between the slide and the tow bar to provide additional functional support. The auxiliary components are arranged as storage slots with an array of storage cavities for removable components such as universal wheels. Elastic clips are installed in the storage cavities to secure the removable components and ensure stable storage.

[0014] Storage components: The storage components include a set of side panels that are slidably mounted on the frame. The frame is provided with a slide groove, and the side panels are inserted into the slide groove and slide back and forth to achieve dynamic adjustment of the loading space. Universal wheels are installed under the side panels to improve the mobility of the side panels. Side blocks are installed on the inside of the side panels. The side blocks are rotatably mounted in the slots on the inside of the side panels. When the side blocks are opened, they can support the storage panels installed between the side panels. Rectangular storage slots are provided on the storage panels for classified placement of items. The storage components also include rubber patches installed at the ends of the side panels. The rubber patches are attached to the outside of the ends of the side panels with Velcro to provide anti-collision and protection.

[0015] Universal caster design: The universal caster consists of a wheel body, a wheel frame, and a mounting base. The wheel body is mounted on the wheel frame via bearings. The wheel frame and mounting base are rotatably connected to achieve 360° rotation, ensuring the cart's full range of mobility. The universal caster is designed with interchangeable features, including but not limited to pneumatic tires and track wheels. It adopts a modular installation method and is installed with clips or bolts to the frame and the bottom of the side panels to adapt to different terrain requirements.

[0016] Intelligent and safe design: A gyroscope sensor integrated into the frame monitors the cart's posture and slope in real time, assisting with anti-slip and safety control, enhancing cargo transport safety. The bottom of the storage tray is equipped with shock-absorbing pads and magnetic strips to protect fragile items, while the magnetic strips help secure cargo to prevent sliding and tipping during transport.

[0017] The present invention provides a dynamic foldable space-optimizing cargo cart system, which has the following beneficial effects: 1. The present invention effectively solves the problems existing in the technical field of cargo carts, such as low space utilization, inconvenient storage, poor scene adaptability, lack of effective cargo fixing devices and anti-slip design, complex folding and unfolding processes, and lack of intelligent functions. It successfully overcomes the limitations of traditional carts in terms of limited cargo carrying area, low handling efficiency, large space occupation, single function, and poor user experience.

[0018] 2. The present invention realizes dynamic switching of single-layer to four-layer loading space through the flexible combination of side panels and storage boards, significantly improving the loading area and being able to adapt to the stacking needs of goods of different volumes. It solves the problem that traditional carts are mostly fixed structures, with limited loading area and the inability to dynamically adjust the loading space according to the size of the goods, resulting in low handling efficiency.

[0019] 3.

[0021] 5. The side panels and storage panels of the present invention can be independently disassembled or folded, and users can quickly adjust the cart shape (such as single-layer, double-layer or extended platform) according to scene requirements, greatly reducing the complexity of operation.

[0022] 6. The universal wheel of the present invention supports multiple replacement options such as pneumatic tires and track wheels. Combined with the slope monitoring function of the gyroscope sensor, it can adapt to complex terrain such as sand, grass, and stairs, reducing manpower consumption. This feature has been verified through multiple tests in actual scenarios (such as shopping malls, warehouses, and moving large furniture).

[0023] 7. The universal wheel design of the present invention enables the cart to easily cope with complex terrains, significantly improving the applicability and flexibility of the cart.

[0024] 8. The present invention provides a method for disassembling the universal wheel to be matched, and utilizing the auxiliary component (specifically, the storage slot) on the control frame, on which storage cavities compatible with the universal wheel are arranged in an array, the user can embed the universal wheel in the storage cavity, thereby completing the storage of the universal wheel.

[0025] 9. The present invention provides exclusive storage space for the universal wheel after the universal wheel to be matched is disassembled, so that the universal wheel can be neatly stored in the storage cavity when not in use, thereby making full use of the space. Users have reported that storage is convenient and space utilization is more reasonable.

[0026] 10. The bottom of the storage board of the present invention is equipped with a shock-proof pad and a magnetic strip to protect fragile items and mark the category of items.

[0027] 11. The frame of the present invention is integrated with a gyroscope sensor to monitor the posture and slope of the cart in real time, prevent the cart from slipping, and improve the safety of cargo transportation.

DETAILED DESCRIPTION

[0034] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0035] Example 1 like Figures 1 to 8 As shown, this embodiment provides a dynamic foldable space-optimized cargo cart system, the specific structure and working principle of which are as follows: 1. Overall structure This dynamic foldable space-optimized cargo cart system is primarily composed of a cart body 100, a control frame 200, a storage component 300, an auxiliary component 400, and universal wheels 500. These components work together to achieve flexible mobility, efficient cargo loading, and space-optimized storage.

[0036] 2. Car body 100 The vehicle body 100 adopts an integral frame structure, consisting of a frame 101 and a skeleton 104. The frame 101 is the basic supporting structure of the entire vehicle body, and is mounted on a set of connecting shaft seats 102. The connecting shaft seats 102 are hinged to the connecting seats 107 on the frame 101 via pins 105. This hinged connection allows the connecting shaft seats 102 to rotate at a certain angle relative to the frame 101.

[0037] The connecting shaft seat 102 is provided with a bottom wheel 103. Figure 8 As shown, the connecting sleeve 1031 of the bottom wheel 103 connects the connecting shaft seat 102 and the frame 104. The bottom wheel 103 includes a connecting sleeve 1031 rotatably mounted on the connecting shaft seat 102, a wheel seat 1032 mounted on the connecting sleeve 1031, and a set of pulleys 1033 rotatably mounted on the wheel seat 1032. Through this multi-layer rotating structure, the bottom wheel 103 can rotate flexibly to adapt to the movement requirements of different ground surfaces.

[0038] The frame 101 is internally integrated with a gyroscope sensor that can monitor the posture and slope information of the cart in real time and transmit the data to the control system to assist in implementing anti-slip and safety control functions, thereby ensuring the stability of the cart in various usage scenarios.

[0039] 3. Control rack 200 The control frame 200 is detachably and slidably mounted on the frame 104. Figure 7 As shown, the control frame 200 includes a slide 201 mounted on the frame 104. A support rod 202 is inserted above the slide 201. A tow bar 203 and an auxiliary component 400 are slidably mounted on the support rod 202. The auxiliary component 400 is installed between the slide 201 and the tow bar 203. Users can adjust the position of the tow bar 203 and the auxiliary component 400 on the support rod 202 by sliding them according to actual usage needs to meet different operating and storage requirements.

[0040] 4. Storage components 300 The storage unit 300 is mounted above the frame 101 and is used to carry items. It comprises a set of side panels 301 slidably mounted on the frame 101. The frame 101 defines a slide slot 106, into which the side panels 301 slide forward and backward. This sliding design allows the side panels 301 to be flexibly adjusted to suit the size and shape of items, improving space utilization.

[0041] A side block 304 is mounted on the inside of the side panel 301. The side block 304 is rotatably mounted in a slot on the inside of the side panel 301. When items need to be placed, the side block 304 is opened to support the rotating storage panel 302. The storage panel 302 is rotatably mounted on the front end of the vehicle frame 101. The storage panel 302 is provided with a rectangular storage slot 303, which can be used to classify and place different items to prevent collisions and slipping during movement. The bottom of the storage panel 302 is equipped with a shock-absorbing pad and a magnetic strip. The shock-absorbing pad can effectively reduce the impact of vibration on items during transportation, and the magnetic strip can enhance the stability of the connection between the storage panel 302 and the side panel 301.

[0042] A rubber patch 305 is attached to the end of the side panel 301 via Velcro. The rubber patch 305 provides cushioning and collision protection, protecting the stroller from damage when it collides with surrounding objects during movement. The Velcro design also makes installation and replacement of the rubber patch 305 quick and easy.

[0043] 5. Auxiliary components 400 The auxiliary component 400 is configured as a storage slot with storage cavities arranged in an array. The storage cavities are adapted to the ends of the universal wheels 500. When the universal wheels 500 are removed, they can be inserted and stored in the storage cavities of the auxiliary component 400, achieving convenient storage of the universal wheels 500 and saving space.

[0044] The auxiliary component 400 further includes an elastic buckle installed in the storage cavity. The elastic buckle can firmly fix the detachable components, including but not limited to the universal wheel 500, to prevent the stored components from falling during the movement of the cart, thereby ensuring the stability and safety of the storage.

[0045] 6. Universal wheel 500 Universal wheels 500 are mounted below the frame 101 and the side panels 301 and can rotate freely to enable flexible movement of the cart. Universal wheels 500 consist of a wheel body, a wheel frame, and a mounting base. The wheel body is mounted on the wheel frame via bearings, and the wheel frame is rotatably connected to the mounting base. This structure enables universal wheels 500 to rotate 360 ​​degrees, meeting the cart's flexible steering requirements in all directions.

[0046] The universal wheel 500 features a replaceable design, including but not limited to pneumatic tires and track wheels, to accommodate various usage scenarios and surface conditions. For example, a standard wheel can be used on flat indoor surfaces, while a pneumatic tire or track wheel can be swapped out for rugged outdoor surfaces to enhance the cart's maneuverability. The universal wheel 500 utilizes a modular installation method, attaching to the frame 101 and the bottom of the side panel 301 via clips or bolts, allowing for quick replacement and maintenance based on actual needs.

[0047] This dynamic foldable space-optimizing cargo cart system achieves versatility and efficiency through the rational design and coordinated operation of the above components, and can meet the cargo and mobility needs of different users in various scenarios.

[0048] Example 2 In another preferred embodiment, based on Example 1, this embodiment provides a dynamic foldable space-optimized cargo cart system, which is used in shopping malls or supermarkets. Its specific structure and application steps are as follows: 1. Description of cart structure: like Figures 1 to 5 As shown, the dynamic foldable space-optimizing cargo cart system in this embodiment includes a body 100, which is configured as an integral frame structure, primarily consisting of a vehicle frame 101 and a skeleton 104. A control frame 200 is detachably and slidably mounted on the skeleton 104. The control frame 200 includes a slide 201 mounted on the skeleton 104. The slide 201 is sleeved onto the skeleton 104, and a support rod 202 is inserted above the slide 201. A tow bar 203 and an auxiliary component 400 are slidably mounted on the support rod 202. The auxiliary component 400 is mounted between the slide 201 and the tow bar 203 and is specifically configured as a storage slot with storage cavities arranged in an array.

[0049] like Figures 3 to 5As shown, a storage unit 300 is mounted above the frame 101 for carrying items. The storage unit 300 comprises a set of side panels 301 slidably mounted on the frame 101. The frame 101 defines a slide slot 106, within which the side panels 301 slide back and forth. Universal wheels 500 are also mounted below the side panels 301 to facilitate flexible movement. Universal wheels 500 are also removably mounted below the frame 101. These wheels comprise a wheel body, a wheel frame, and a mounting base. The wheel body is mounted on the wheel frame via bearings, and the wheel frame and mounting base are rotatably connected to enable 360° rotation.

[0050] like Figure 8 As shown, the vehicle body 100 has a frame 101 equipped with a set of connecting shaft seats 102, on which are mounted bottom wheels 103. The bottom wheels 103 include connecting sleeves 1031 rotatably mounted on the connecting shaft seats 102. The connecting sleeves 1031 connect the connecting shaft seats 102 and the frame 104. The connecting sleeves 1031 are equipped with wheel seats 1032, on which a set of pulleys 1033 are rotatably mounted. The frame 101 is provided with a connecting seat 107, which is hinged to the connecting seat 107 on the frame 101 via a pin 105.

[0051] like Figure 4 and Figure 5 As shown, side blocks 304 are mounted on the inside of the side panels 301. These blocks 304 are rotatably mounted within slots on the inside of the side panels 301. When opened, they support a storage panel 302 mounted between the side panels 301. The storage panel 302 is provided with rectangular storage slots 303 for storing small items. The storage component 300 also includes rubber patches 305 mounted on the ends of the side panels 301. These patches are attached to the outside of the ends of the side panels 301 using Velcro to increase friction and prevent items from sliding.

[0052] like Figure 3 and Figure 6 As shown, the auxiliary component 400 is provided with storage cavities arranged in an array, and the storage cavities are adapted to the ends of the universal wheels 500. After the universal wheels 500 are removed, they are embedded and stored in the storage cavities provided in the auxiliary component 400; the auxiliary component 400 also includes elastic clips, which are installed in the storage cavities and are used to fix detachable components such as the universal wheels 500. The universal wheels 500 are replaceable in design, including but not limited to pneumatic tires and track wheels, and are installed in a modular manner, and are installed together with the frame 101 and the bottom of the side plates 301 by clips or bolts. A gyroscope sensor is integrated inside the frame 101 for real-time monitoring of the cart's posture and slope, and to assist in anti-slip and safety control. The bottom of the storage plate 302 is equipped with shock-absorbing pads and magnetic strips to protect fragile items and mark the category of items.

[0053] 2. Specific application steps: (1) Unfold the cart: Figure 4 As shown, the user first pulls out the side panels 301 at both ends of the frame 101 along the slide slots 106 until the side panels 301 are fully extended. Then, the side blocks 304 are rotated and opened to a horizontal position, and the side blocks 304 support the storage plate 302 to form a stable loading platform.

[0054] (2) Adjust the carrier layer: Figure 3 As shown, depending on the quantity and volume of items purchased, the user can choose whether to flip the storage plate 302 to create a double-layer loading structure. For larger items, the storage plate 302 can be flipped 180° and secured in the retaining slots on the inside of the frame 101, creating a double-layer loading space. The rectangular storage slots 303 on the storage plate 302 are used to categorize small items, and the bottom cushion protects fragile items.

[0055] (3) Secure the cargo: Place fragile items such as glassware in the rectangular storage slot 303 of the storage plate 302 and secure them with anti-slip pads. Large items such as cartons and electrical appliances are placed on the extended platform formed by the side plate 301 and the frame 101, and are secured with straps in the storage cavity of the auxiliary component 400.

[0056] (4) Moving the cart: Adjust the bottom wheel 103 to the straight-ahead mode and the universal wheel 500 to the 360° rotation mode to ensure the cart can flexibly turn in narrow passages. Push the tow bar 203 and use the gyroscope sensor to monitor the cart's posture and slope in real time to prevent it from slipping.

[0057] (5) Storage cart: After the purchase is completed, Figure 2 As shown, rotate the storage plate 302 and retract it. Slide the side plates 301 inward along the slide slots 106 until fully retracted. Fold the frame 104, remove the universal wheels 500, insert them into the storage cavity of the auxiliary component 400, and secure them with elastic clips. Finally, hang the cart in a locker or store it in a corner.

[0058] Example 3 In another preferred embodiment, based on embodiments 1 and 2, this embodiment provides a dynamic foldable space-optimized cargo cart system, which is a cart application in a warehouse cargo handling scenario. Its specific structure and application steps are as follows: 1. Cart structure: The cart structure of this embodiment is similar to that of Examples 1 and 2, but has been specifically optimized for warehouse environments. The assembly relationship of the vehicle body 100, control frame 200, storage unit 300, and universal wheels 500 is the same as in Examples 1 and 2. However, the storage plate 302 in the storage unit 300 features additional partitions and classification labels, facilitating quick sorting and access to different types of parts and tools. Furthermore, the universal wheels 500 feature a replaceable design, supporting either pneumatic tires or tracks to accommodate complex and varied warehouse terrain, such as sand, grass, or stairs.

[0059] 2. Specific application steps: (1) Adjusting the cart structure: Depending on the size and quantity of the cargo to be transported, the user can choose whether to unfold the side panels 301 and side blocks 304. If the cargo is light and small, only the frame 101 itself can be used to carry the cargo. If the cargo is long or wide, the side panels 301 and side blocks 304 can be unfolded to form an extended platform to increase the cargo carrying area.

[0060] (2) Classified storage of goods: Use the rectangular storage slots 303 and partitions on the storage plate 302 to classify and store different types of parts and tools. Affix corresponding classification labels to facilitate quick search and access. Lightweight items can be hung on the hooks of the auxiliary components 400 on the control frame 200 to further save space. The rubber patches 305 attached to the ends of the side plates 301 increase friction and prevent goods from sliding.

[0061] (3) Adapting to complex terrain: If the warehouse floor is uneven or there are stairs or other complex terrain, the user can replace the universal wheel 500 with a pneumatic tire or track wheel to enhance the cart's passability and stability. Adjust the direction of the bottom wheel 103 to the straight-ahead mode, and the universal wheel 500 maintains a 360° rotation mode to ensure that the cart can move flexibly in complex terrain.

[0062] (4) Transport and secure: Push the cart to the cargo storage area, move the cargo onto the cart, and secure it with straps. During the transport process, the gyroscope sensor monitors the cart's posture and slope in real time to prevent the cart from slipping due to uneven ground or slopes, ensuring safe transport.

[0063] (5) Transport and storage: After transport is complete, the user retracts the side panels 301 into the chute 106, folds the frame 104, removes the universal wheels 500, and inserts them into the storage cavity of the auxiliary component 400. Secure them with elastic buckles to prevent loss. Finally, push the cart to a corner of the warehouse or a designated storage area to save space and facilitate next use.

[0064] In the preferred embodiment, the vehicle body 100 includes a frame 101, on which a set of connecting axle seats 102 are installed, on which bottom wheels 103 are mounted, and connecting sleeves 1031 of the bottom wheels 103 connect the connecting axle seats 102 and the skeleton 104 together; the above arrangement makes the vehicle body 100 structurally stable and mobile, and the skeleton 104 further supports the vehicle body, thereby enhancing the overall load-bearing capacity; at the same time, the design of the connecting sleeves 1031 facilitates the rapid disassembly and maintenance of the bottom wheels 103, thereby improving the ease of use of the vehicle body.
