Description

Technical Field

[0001] This invention relates to the field of vehicle component technology, and more specifically, to a multifunctional storage device for a vehicle and a vehicle having the same. Background Technology

[0002] Currently, long-haul truck users have an urgent need for mobile phone storage and charging in the cab, as well as mobile phone holders for convenient short video viewing. They also need a table to facilitate functions such as eating simple meals and temporary work. However, the cost of mobile phone holders and table configurations pre-installed by OEMs is relatively high. Compared with the original equipment manufacturer (OEM) configuration, third-party mobile phone holders and table configurations from online shopping platforms such as Taobao offer better value for money, but they lack convenient and stable installation methods in the cab.

[0003] There is currently no effective solution to the aforementioned technical problems. Summary of the Invention

[0004] The main objective of this invention is to provide a multifunctional storage device for vehicles and a vehicle having the same, in order to solve the technical problem in the prior art that commercial vehicle sleeper areas lack low-cost, highly adaptable quick-connect interfaces, which makes it impossible for users to conveniently install third-party mobile phone holders, tables and other personal items.

[0005] To achieve the above objectives, according to one aspect of the present invention, a multifunctional storage device for a vehicle is provided, comprising: a storage box; the storage box having a plurality of storage areas, at least one of the storage areas having an opening structure at its top, wherein a positioning structure is provided on the side wall of the opening structure, the storage area having the opening structure is used to accommodate a mobile device, wherein the mobile device has a storage position within the storage area having the opening structure, and the mobile device has a fixed position placed on the positioning structure to allow a target object to view and use the mobile device.

[0006] Furthermore, the multiple storage areas include a first storage area, a second storage area, and a third storage area. The first storage area and the second storage area are arranged adjacent to each other along the width direction of the storage box, and the first storage area and the third storage area are arranged adjacent to each other along the length direction of the storage box.

[0007] Furthermore, the top of the first storage area is provided with an opening structure, and the interior of the first storage area forms a receiving body for accommodating mobile devices. The receiving body has positioning structures at both ends, wherein the positioning structure is a groove, and the bottom surface of the groove forms an angle of 100°~120° with the horizontal plane; the first side of the receiving body is a planar structure, which is adjacent to the positioning structure; the second side of the receiving body is provided with a second limiting groove, which is opposite to the first side.

[0008] Furthermore, the storage box includes: a shell, on which a wiring harness hole is provided, the wiring harness hole being connected to the first storage area, wherein the edge of the wiring harness hole is chamfered.

[0009] Furthermore, the shell has a flange structure on the side near the vehicle side panel. The flange structure is higher than the opening of the second storage area. The raised structure has multiple mounting holes, and the shell is connected to the vehicle through the mounting holes.

[0010] Furthermore, the second storage area has an opening at the top, and the opening size of the second storage area is smaller than the opening size of the opening structure of the first storage area. The second storage area is used to accommodate small-sized daily necessities.

[0011] Furthermore, a first receiving cavity is formed inside the third storage area, and the top of the third storage area is open. At least two first limiting grooves are provided on the edge of the opening of the third storage area. The two first limiting grooves are spaced apart along the circumference of the opening. The two first limiting grooves are used to fix at least one of the table or vehicle bar.

[0012] Furthermore, the bottom of the storage box is equipped with at least one hook, which is made of plastic.

[0013] According to another aspect of the present invention, a vehicle is provided having a multi-functional storage device, which is the multi-functional storage device described above.

[0014] Furthermore, the vehicle includes: a side panel; a berth connected to the side panel; a multi-functional storage device located above the berth, with one side of the multi-functional storage device connected to the side panel.

[0015] By applying the technical solution of this invention, a storage area with a specific opening structure is set inside the storage box, enabling rapid switching between storage and use states for mobile devices. The storage box has multiple functional zones, at least one of which has an opening structure at the top. A positioning structure is integrated into the side wall of this opening structure. This positioning structure does not interfere with the free placement and removal of the mobile device in a non-contact state. However, when the mobile device is taken out of the storage area in a specific posture and placed on top of the opening structure, it is reliably positioned by the positioning structure, thus stably transferring the mobile device from a storage position to a fixed position. This facilitates viewing the screen and operating the device while driving or resting. This design abandons traditional external brackets or adhesive structures, requiring no additional accessories. Through the structural innovation of the storage box itself, it achieves concealed storage and immediate use of mobile devices, balancing safety, neatness, and ease of use. It is particularly suitable for scenarios with limited space and complex operating environments, such as sleeper berths in commercial vehicles, effectively improving the user experience of smart devices during travel while reducing safety risks caused by device shaking or accidental touches.

[0037] Patent document 1 discloses a storage box for the lower berth of a heavy-duty commercial vehicle. The storage box, featuring a storage cavity and a cover, is located at the end of the berth body. The storage cavity is located inside the box, and a cover is provided at the opening of the cavity. A lamp mounting bracket is provided on the outer wall of the box, and a lamp is installed in the bracket. Both the lamp and the power socket are electrically connected to the vehicle's power supply. This patent utilizes the storage cavity for storing items, while the lamp in the mounting bracket provides auxiliary lighting to the berth area. The power socket allows for charging of electronic devices such as mobile phones and audio equipment, thereby improving the comfort of passengers.

[0038] Patent document 2 discloses a storage area for a sleeper car, including a base, a storage assembly, and a mounting assembly. The storage assembly includes two mounting brackets vertically positioned on the upper part of the base. Each bracket has three rectangular control holes on one side, and a pair of positioning grooves are formed inside the control holes. A positioning shaft is laterally rotatably mounted inside the positioning grooves, and a placement plate is fixedly mounted in the center of the positioning shaft. Placement plates are rotatably mounted inside each of the three control holes. Passengers' luggage is stored using the storage assembly, with the base and storage assembly working together to store luggage bags. The mounting assembly secures the storage area to the car wall, facilitating installation and removal of the storage area as needed.

[0039] The aforementioned patent document 1 describes a sleeper storage box located at the end of the sleeper berth, integrating a lamp holder and a power socket. This allows users to store personal belongings, provide auxiliary lighting in low-light conditions, and temporarily charge small electrical devices while resting in the sleeper area. However, its functionality and location do not allow for quick access to a phone holder or tabletop for convenient phone use, temporary meals, or work, thus limiting its practicality.

[0040] The aforementioned patent document 2 provides a sleeper car storage area with a relatively simple function, a relatively complex structure, and a large space occupation. It is more suitable for storing and securing items such as luggage on trains, but has no practical significance for the daily life needs of commercial truck cabs.

[0041] Combination Figures 1 to 5 As shown, according to a specific embodiment of this application, a multifunctional storage device for a vehicle is provided.

[0042] Specifically, such as Figure 1 As shown, the multifunctional storage device includes: a storage box 100; the storage box 100 has multiple storage areas, and at least one of the storage areas has an opening structure 10 at its top. The opening structure 10 has a positioning structure 11 on its side wall. The storage area with the opening structure 10 is used to accommodate a mobile device. The mobile device has a storage position within the storage area with the opening structure 10, and a fixed position on the positioning structure 11 for the target object to view and use the mobile device.

[0043] By applying the technical solution of this invention, a storage area with a specific opening structure is set inside the storage box, enabling rapid switching between storage and use states for mobile devices. The storage box has multiple functional zones, at least one of which has an opening structure at the top. A positioning structure is integrated into the side wall of this opening structure. This positioning structure does not interfere with the free placement and removal of the mobile device in a non-contact state. However, when the mobile device is taken out of the storage area in a specific posture and placed on top of the opening structure, it is reliably positioned by the positioning structure, thus stably transferring the mobile device from a storage position to a fixed position. This facilitates viewing the screen and operating the device while driving or resting. This design abandons traditional external brackets or adhesive structures, requiring no additional accessories. Through the structural innovation of the storage box itself, it achieves concealed storage and immediate use of mobile devices, balancing safety, neatness, and ease of use. It is particularly suitable for scenarios with limited space and complex operating environments, such as sleeper berths in commercial vehicles, effectively improving the user experience of smart devices during travel while reducing safety risks caused by device shaking or accidental touches.

[0044] Specifically, the multiple storage areas include a first storage area 1, a second storage area 2, and a third storage area 6. The first storage area 1 and the second storage area 2 are arranged adjacent to each other along the width direction of the storage box 100, and the first storage area 1 and the third storage area 6 are arranged adjacent to each other along the length direction of the storage box 100.

[0045] In an optional embodiment, the third storage area 6 is used to store a water cup or to fix at least one of a tabletop or a vehicle bar, the second storage area 2 is used to store at least one of a lighter or a mobile phone data cable, and the first storage area 1 is used to store a mobile phone or a mobile device.

[0046] Optionally, such as Figure 1As shown, the interior of the storage box 100 is divided into three functionally independent but structurally coordinated storage areas: a first storage area 1, a second storage area 2, and a third storage area 6. The first storage area extends laterally in the same direction as the width of the storage box 100, and is used to accommodate mobile devices, such as smartphones. It works in conjunction with the top opening structure 10 and the positioning structure 11 to store and secure the device. The second storage area 2 is located to one side of the first storage area 1, adjacent to it along the width of the storage box 100. Both share the same side wall or middle partition. This layout allows the second storage area 2 to be close to the area where the user's hand naturally hangs down or rests, facilitating quick access to small personal items such as lighters, keys, or mobile phone charging cables. Its volume is designed based on the shape of common lighters and foldable data cables on the market, avoiding wasted space. The third storage area 6 is located above or diagonally above the first storage area 1, extending adjacent to the first storage area 1 along the length of the storage box 100. Its internal dimensions are adapted to the quick-release bases for commonly used water cups, vehicle tables, or bar counters. This arrangement allows users to drink water or install tables without having to reach out significantly when leaning against the berth. Furthermore, the length extension avoids functional interference with the second storage area 2 in the width direction. Together, these three areas form a spatial combination structure of "horizontal parallel arrangement + vertical extension," which fully utilizes the limited three-dimensional space between the rear of the vehicle and the berth, while also ensuring an orderly distribution of functional areas within the natural operating radius of the human body: mobile phone storage and use are centrally located, small items are conveniently stored on the side, and cups and table counters are conveniently located below, forming an ergonomic "three-dimensional functional flow." This maximizes the functionality, optimizes operation, and enhances the comfort of use of the storage device within a limited space.

[0047] Optionally, the second storage area 2 in the multi-functional storage device has its length, width and depth dimensions designed according to the common lighter sizes on the market, which can meet the storage needs of users with smoking habits for lighters, and can also accommodate mobile phone charging cables.

[0048] Specifically, the first storage area 1, the second storage area 2, and the third storage area 6 are set up independently.

[0049] Specifically, the first storage area 1 has an opening structure 10 at the top, and a receiving body is formed inside the first storage area 1. The receiving body is used to receive mobile devices. The receiving body has positioning structures 11 at both ends. The positioning structure 11 is a groove, and the bottom surface of the groove forms an angle of 100° to 120° with the horizontal plane. The first side of the receiving body is a planar structure 13, which is adjacent to the positioning structure 11. The second side of the receiving body has a second limiting groove 12, which is opposite to the first side.

[0050] In one specific embodiment, the top of the first storage area 1 is provided with an opening structure 10. The opening structure 10 is a rectangular through-hole formed by a partial opening in the top wall of the storage box 100. Its horizontal width is slightly larger than the width of mainstream large-sized smartphones on the market, and its vertical length is adapted to the projected size of the phone in the length direction, so that the mobile device can be freely inserted or removed in the vertical direction. Below the opening structure 10 is an internal receiving body, which is a closed cavity formed by the inner wall of the storage box 100. Its depth is greater than two-thirds of the height of the phone, ensuring that the phone can be fully supported after being placed vertically, and is not easy to shake or tip over.

[0051] In an optional embodiment, positioning structures 11 are respectively provided on the inner walls of both ends of the receiving body along the length direction. The positioning structure 11 is a groove structure. The depth of the groove is one-third of the width of the mobile phone. The width of the groove opening matches the thickness of the side of the mobile phone. The bottom surface of the groove forms a 120° inclined angle with the horizontal plane. This angle setting allows the back of the mobile device to naturally fit against the inclined bottom surface of the groove when it is taken out of the receiving body and placed horizontally on the groove, with the screen facing the user's front, forming a stable and unsupported posture, which is convenient for watching short videos, answering calls, or performing simple operations.

[0052] A planar structure 13 is provided on the outer edge of the first side of the receiving body. This planar structure 13 is a smooth, flat surface without any texture. It is made of injection-molded high-gloss ABS or PC material with a surface roughness Ra≤1.6μm. It is used to form an airtight fit with the suction cup base of the vacuum adsorption mobile phone holder, so as to achieve adsorption and fixation of the mobile phone at different angles. The planar structure 13 and the positioning structure 11 are arranged adjacent to each other at the same end of the receiving body. The two are arranged sequentially along the longitudinal direction, so that the user can quickly switch between the two usage modes of "oblique holding" and "vacuum adsorption" on the same side.

[0053] like Figure 3As shown, a second limiting groove 12 is provided on the second side of the receiving body. The second limiting groove 12 is a shallow groove extending longitudinally along the side wall of the receiving body. The second limiting groove is a recessed through groove integrally formed on the inner wall of the storage box. Its cross-sectional profile is teardrop-shaped, wider at the top and narrower at the bottom. The width of the upper arc transition area matches the outer diameter of current mainstream mobile phone charging data cables (including the outer diameter of common plugs such as USB-A, USB-C, and Lightning), with a value range of 5mm to 7mm, ensuring that the data cable can be naturally inserted without loosening. Its lower tip area is a transitionally narrowed structure with a depth twice the outer diameter of the data cable, i.e., 10mm to 14mm. This depth design ensures that after the data cable is inserted, its cable body is completely contained in the groove, with only the plug end slightly exposed above the groove opening. This prevents the cable from popping out or getting tangled due to bumps during vehicle operation and avoids the cable being pulled by external force directly impacting the connection point between the plug and the device. The surface of the groove 2 is smooth and burr-free, with a surface roughness Ra≤3.2μm, to reduce the risk of wear on the data cable insulation layer during repeated insertion, removal, and clamping. The second limiting groove 12 extends longitudinally along the inner wall of the first storage area 1, with a gentle slope at its entrance end, facilitating quick and easy insertion of the data cable with one hand. The exit end is adjacent to the entrance area of ​​the wire harness hole 4, allowing the clamped data cable to be naturally guided to the charging interface, forming an integrated "storage-guidance-connection" path. Without adding additional buckles, clips, or elastic elements, this structure achieves adaptive clamping and orderly placement of flexible cables through only the spatial constraint and depth ratio design of the teardrop-shaped cross-section. It effectively solves the problems of messy tangling, easy crushing, and easy breakage of charging cables in traditional storage boxes. It is especially suitable for the compact space and limited operation environment of commercial vehicle sleeper areas, significantly improving the efficiency of users' access to charging equipment and the safety of use during rest periods.

[0054] In one specific embodiment, the groove is a physical limiting structure disposed on the inner walls of both ends of the receiving body in the first storage area 1. Its depth is precisely limited to one-third of the width of the current mainstream large-sized smartphones on the market. This width is based on the five most commonly used models of commercial vehicles with the highest market share in 2023 and 2024 (such as iPhone). Based on the measured average width of phones such as the iPhone 15 Pro Max, Huawei Pura 70 Ultra, and Xiaomi 14 Ultra, the groove ranges from 20mm to 25mm. Correspondingly, the groove depth is set to 6.5mm to 8.5mm to ensure that when the phone is placed horizontally on the groove, its sides are completely embedded, with only about two-thirds of the screen area exposed at the top, providing stable support without tilting or slipping. The groove width is uniform along its length and strictly corresponds to the thickness of the aforementioned mainstream large-sized phones. This thickness is set based on measured data of the thickest part of the typical model's body (usually the camera bump area or the mid-frame structure), ranging from 7.5mm to 9.5mm. The groove width is correspondingly designed to be 8mm to 10mm, ensuring the phone... The sides maintain a slight gap of 0.5mm to 1.5mm between the phone and the groove wall after insertion, ensuring smooth insertion and removal of the phone while preventing it from shifting out of the groove's restraints during vehicle bumps or slight user touches. The bottom surface of the groove is inclined at 100° to 120° to the horizontal plane, forming a three-dimensional positioning geometry system together with the groove width and depth. This allows the phone's back to naturally conform to the inclined surface when placed horizontally, with the screen tilted forward at an angle that aligns with human eye vision. This allows for extended viewing without external force. Furthermore, this structure is widely adaptable to phones of different thicknesses and widths, requiring no user adjustments or additional accessories. The stable horizontal user experience is achieved simply by matching the groove's dimensions and spatial configuration.

[0055] Specifically, the storage box 100 includes: a housing 101, on which a wire harness hole 4 is provided, the wire harness hole 4 being connected to the first storage area 1, wherein the edge of the wire harness hole 4 is chamfered.

[0056] The storage box 100 is composed of a one-piece injection-molded shell 101. The shell 101 is a box-shaped structure with a closed bottom wall and side walls. Its internal space is divided into multiple functional storage areas, of which the first storage area 1 is used to accommodate mobile devices. A wire harness hole 4 is provided on the bottom wall or side wall of the shell 101 near the lower part of the first storage area 1. The wire harness hole 4 is a through hole that penetrates the wall thickness of the shell 101. Its diameter is determined according to the plug diameter and flexible bending radius of mainstream mobile phone charging data cables on the market. The diameter range is 8mm to 12mm, which ensures that the MicroUSB, USB-C or Lightning end of the charging cable can be smoothly inserted. At the same time, it allows the cable to form a natural bending arc of not less than R5mm after passing through the hole, avoiding wire core breakage or insulation aging due to excessive bending. The wiring harness hole 4 is directly connected to the receiving cavity of the first storage area 1, so that the charging cable can extend from the power harness inside the vehicle along the rear sheet metal to the inside of the housing 101, and pass through the opening structure of the first storage area 1 through the wiring harness hole 4, thereby connecting with the USB port 3. This allows the charging cable to hang naturally and connect to the charging interface without tension when the mobile device is vertically stored in the first storage area 1, avoiding the device shaking or the plug loosening due to pulling. The edge of the wire harness hole 4 has a uniform chamfer structure around the hole, with a chamfer angle of 15° to 30° and a chamfer width of 0.5mm to 1.2mm. This chamfer structure is used to eliminate the sharp edges formed during the injection molding of the housing 101, preventing the outer insulation of the charging cable from being worn or torn due to friction during repeated insertion, effectively improving the service life and electrical safety performance of the cable. The chamfer edge is polished, with a surface roughness Ra≤3.2μm, further reducing the coefficient of friction and ensuring that the cable maintains good flexibility and sealing during long-term use, avoiding the risk of short circuit caused by insulation layer damage.

[0057] Specifically, the housing 101 has a flange structure 8 on the side near the vehicle side panel. The flange structure 8 is higher than the opening of the second storage area 2. The flange structure has multiple mounting holes, and the housing 101 is connected to the vehicle through the mounting holes.

[0058] like Figure 1As shown, the housing 101 has a continuously extending flange structure 8 along one edge of its length. This flange structure 8 is a plate-shaped flange formed by vertically bending the side wall of the housing 101 outwards. Its height is at least 5mm higher than the upper edge of the opening of the second storage area 2, so that the flange structure 8 forms a shield and protection for the opening of the second storage area 2 when installed, preventing items inside the storage area from accidentally slipping out due to accidental contact or collision when the user takes out a lighter or data cable. The thickness of the flange structure 8 is the same as the wall thickness of the main body of the housing 101, which is 2.0mm. The diameter is Φ4.5mm to 2.5mm to ensure the overall structural rigidity and consistency with the injection molding process. Four mounting holes are evenly distributed along the length of the planar area of ​​the flange structure 8. Each mounting hole is a through hole with a diameter of Φ4.5mm. The center of each hole is 8mm from the outer edge of the flange structure 8, and the spacing between the holes is 120mm to 150mm. This layout corresponds to the pre-set threaded holes or mounting bracket holes on the rear panel of the commercial vehicle, ensuring that the housing 101 can be securely connected using self-tapping screws or standard bolt assemblies. The edges of all mounting holes are chamfered. The chamfer angle is 15° and the chamfer width is 0.5mm, used to eliminate sharp edges generated by stamping or drilling, avoiding damage to wiring harnesses or interior trim materials during installation; the mounting surface of the flange structure 8 is treated with flatness tolerance ≤0.3mm to ensure no gaps between it and the vehicle's rear panel, improving structural rigidity and vibration resistance after installation; in the installed state, the flange structure 8 forms a tight connection with the vehicle side panel, making the storage box 100 rigidly coupled to the vehicle body, effectively suppressing resonance or displacement caused by vehicle bumps. The design ensures that the storage box 100 is installed at a height between 400mm and 500mm from the upper surface of the berth 200, so that the user's elbows can rest naturally on the first storage area 1 and the third storage area 6 without having to raise their arms or lean forward, achieving a precise match between human and machine dimensions. The flange structure 8 abandons the traditional non-structured fixing methods such as pasting, clips or double-sided tape, and achieves a reliable, detachable and maintainable rigid installation by connecting only metal bolts, meeting the high reliability, long service life and maintenance convenience requirements of commercial vehicles.

[0059] In another specific embodiment, the housing 101 is provided with 4 mounting holes, and the multi-functional storage device is fixed to the rear of the vehicle by 4 screws.

[0060] Specifically, the second storage area 2 has an opening at the top, and the opening size of the second storage area 2 is smaller than the opening size of the opening structure 10 of the first storage area 1. The second storage area 2 is used to accommodate small-sized daily necessities.

[0061] The second storage area 2 is located on one side of the housing 101 in the width direction. It has an independent opening at the top. The opening is a rectangular through-hole. Its lateral width and longitudinal length are both smaller than the opening size of the opening structure 10 of the first storage area 1. The width of the opening of the second storage area 2 ranges from 25mm to 35mm, and the length ranges from 50mm to 65mm. This size range is determined based on the shape of the small daily necessities carried by mainstream commercial truck users on the market, including the longest projection size of items such as lighters, keys, coins, small tools, foldable charging heads, earplugs, and windproof masks.

[0062] In contrast, the opening structure 10 of the first storage area 1 is typically between 70mm and 85mm wide, designed specifically for accommodating large mobile devices such as smartphones. The opening size of the second storage area 2 is designed to be approximately 40% to 50% of the former's width, creating a clear size hierarchy. This allows users to quickly distinguish between the two storage functions visually and tactilely, preventing the phone from being mistakenly placed in the second storage area 2 and becoming stuck or damaged. The internal cavity depth of the second storage area 2 is 40mm to 55mm, slightly greater than the maximum thickness of the items it can hold, ensuring that the items are completely contained within the cavity when folded, without being exposed or protruding. This prevents items from popping out due to bumps during driving or interfering with surrounding components. The inner wall surface of this storage area has a smooth, textureless structure with no slots or protrusions, facilitating quick one-handed access to small items. This is especially suitable for scenarios where the driver can operate with one hand without visual confirmation during rest.

[0063] The opening edge of the second storage area 2 has a slight rounded corner with a radius of curvature of 1mm to 2mm to prevent sharp edges from scratching the user's fingers or clothing. Due to its limited opening size, the second storage area 2 cannot accommodate large items, thus forming a natural "anti-misplacement" mechanism. This guides users to store small items such as lighters and keys separately from valuable electronic devices such as mobile phones, avoiding squeezing, scratching, or contamination of charging ports caused by mixed storage. Without adding isolation baffles, partition doors, or flexible covers, this structure achieves physical guidance for the classification and storage of items solely through the differentiated design of the opening size. The structure is simple, low-cost, and highly reliable, making it particularly suitable for use scenarios in commercial vehicle sleeper areas with limited space, frequent operations, and environmental vibrations. It significantly improves the user's efficiency in managing personal belongings and enhances the sense of order in use.

[0064] Specifically, the third storage area 6 forms a first receiving cavity inside, the top of the third storage area 6 is open, and the edge of the opening of the third storage area 6 is provided with at least two first limiting grooves 61. The two first limiting grooves 61 are arranged at intervals along the circumference of the opening, and the two first limiting grooves 61 are used to fix at least one of the table or vehicle bar.

[0065] Specifically, the third storage area 6 is an independent cavity located in the lower part of the length direction of the housing 101. Inside it, a first receiving cavity with a rectangular cross-section is formed. The first receiving cavity has a lateral width of 100mm to 130mm, a longitudinal depth of 90mm to 110mm, and a height of 40mm to 50mm. This size range is determined based on the mainstream car water cup capacity (such as a 500ml thermos cup) and the outline of folding car tables and detachable car bar bases commonly found on third-party online shopping platforms. This ensures that frequently used water cups can be stably placed without tipping over, while allowing the quick-release base of the table or bar to be accommodated in the same space without interfering with the cup body.

[0066] The top of the third storage area 6 is an open structure with a horizontally arranged annular plane at the edge of the opening. At least two first limiting grooves 61 are provided circumferentially on the annular plane. The two first limiting grooves 61 are located on the symmetrical sides of the opening, extending radially along the length of the opening. The width is 8mm to 12mm and the depth is 4mm to 6mm. The bottom surface of the groove is parallel to the horizontal plane, and its position corresponds to the buckle protrusion or positioning pin provided on the bottom of the commercially available vehicle table or bar base. When the user inserts the pin of the table or bar base from top to bottom into the first limiting groove 61, the pin slides along the length of the groove to the end, thereby achieving lateral limiting. This makes the table constrained by the side wall of the first receiving cavity in the vertical direction and symmetrically clamped by the two limiting grooves in the horizontal direction, forming a three-point stable support structure, which effectively resists lateral swaying and longitudinal vibration during vehicle operation.

[0067] The edges of the first limiting groove 61 are rounded by 2mm to 3mm to prevent sharp edges from scratching or causing stress concentration on the plastic or metal parts of the table base. The center distance between the two first limiting grooves 61 is 80mm to 100mm, consistent with the pin spacing of over 90% of commercial tabletops on the market, ensuring universal compatibility. The opening height of the third storage area 6 is flush with or slightly lower than the bottom of the first storage area 1, so that the tabletop height after installation is basically consistent with the height of the user's naturally hanging elbow when leaning against the berth, within the range of 400mm to 480mm, which meets the comfortable operating range of 95% of human sitting postures, facilitating... Users can eat, write, or operate their mobile phones or tablets while resting. This structure, without using bolts, buckles, magnetic or elastic clamping mechanisms, achieves quick installation and convenient disassembly of the table or bar only through the geometric cooperation of the first receiving cavity and two symmetrical limiting grooves. Users can complete the "plug-in-lock-use" operation in one second, and can also disassemble it with one hand. It meets the needs of commercial vehicle users who frequently switch between "storage" and "office / dining" modes in the rest area. At the same time, it avoids the defects of traditional adhesive and clamping devices that are easy to loosen, wear, and unstable, significantly improving the multi-functional user experience and product reliability of the sleeper area.

[0068] Optionally, the two first limiting grooves 61 are arranged diagonally, or opposite each other along the width direction of the third storage area 6, or opposite each other along the length direction of the third storage area 6.

[0069] Three different arrangement methods are adopted: First, two first limiting grooves 61 are arranged opposite each other along the width direction of the third storage area 6, that is, the line connecting the centers of the two grooves is parallel to the width axis of the shell 101, the groove openings face each other, and the distance is 80mm to 100mm. This arrangement method is suitable for folding tabletops with horizontal inserts at the bottom. The inserts are located on both sides of the tabletop. When the tabletop is inserted vertically from above, the inserts slide in along the length of the groove and are locked at the bottom of the groove, thereby constraining the lateral displacement of the tabletop. At the same time, the front and rear side walls of the third storage area 6 are used to restrict its longitudinal movement, forming a stable rectangular positioning frame.

[0070] Secondly, the two first limiting grooves 61 are arranged opposite each other along the length of the third storage area 6, that is, the line connecting the centers of the two grooves is parallel to the length axis of the housing 101, the groove openings face each other, and the distance between them is 100mm to 120mm. This arrangement is suitable for vehicle bar counters or telescopic worktables with longitudinal feet at the bottom. Such products usually have a long base structure. The longitudinal feet can be inserted into the limiting groove to achieve locking in the front and rear directions, preventing the table from sliding forward or backward when the user tilts forward or presses lightly. At the same time, the side walls form a lateral limit to ensure overall stability.

[0071] Third, the two first limiting grooves 61 are arranged opposite each other along the diagonal direction, that is, the two grooves are located at the diagonal vertex areas of the opening respectively, and the line connecting them is the diagonal of the opening of the third storage area 6. The spacing is consistent with the length of the diagonal. This arrangement is suitable for multi-functional modular tabletops with a diamond-shaped or asymmetrical plug layout at the bottom. The plugs are distributed diagonally. The limiting grooves along the diagonal direction achieve spatial cross locking, effectively suppressing the rotation or tilting of the tabletop in any direction and improving torsional stiffness. It is especially suitable for users who need high stability when dining for two people or working collaboratively in a small sleeping area.

[0072] All three arrangement methods mentioned above are achieved through mold structure during the injection molding stage of the shell 101. The slot size, depth, chamfer, and surface finish are consistent, with differences only in spatial orientation. This allows the same storage device to be compatible with the three mainstream types of quick-connect tabletops or bar counters on the market, without requiring users to change devices or make additional selections. In actual use, users can choose the matching limiting slot layout according to the base structure characteristics of the purchased tabletop. If the tabletop does not have a clear insertion direction, the diagonal arrangement method can be used first, as it provides the most comprehensive space constraints. This structural design enables a single device to be compatible with multiple product forms, achieving "one box to fit multiple boards," which greatly improves the versatility of the device and the user's purchasing freedom. At the same time, it avoids compatibility failures or redundant parts caused by dedicated interfaces. It is a structural-level solution for the diverse and personalized usage needs of commercial vehicle sleeper areas.

[0073] Specifically, the bottom of the storage box 100 is provided with at least one hook 7, which is made of plastic.

[0074] like Figure 4 As shown, the bottom outer surface of the storage box 100 is provided with at least one hook 7 at one or both ends along its length. The hook 7 is a cantilever structure integrally injection molded from the bottom of the storage box 100, and its overall shape is J-shaped or L-shaped with a bend. The hook body extends downward from the bottom wall, and the hook tip is rounded with a radius of curvature of 1.5mm to 2.5mm to avoid sharp edges scratching hanging items or the user's clothing. The cantilever length of the hook 7 is 15mm to 25mm, and the vertical distance from its free end to the bottom wall of the storage box 100 is 20mm to 30mm. This height space is sufficient to accommodate the handle structure of common keychains, glasses cases, hat brims, the rim of car trash bags, or small self-purchased car trash cans, ensuring that hanging items do not touch the ground or side interior during vehicle operation, and do not interfere with the sleeper berth or other items. The armrest operates normally; the hook 7 has a rectangular or elliptical cross-section with a thickness of 2.0mm to 3.0mm, consistent with the wall thickness of the main body of the storage box 100, ensuring no weak points during injection molding and possessing sufficient structural rigidity to withstand a static load of no more than 1.5kg, meeting the user's daily needs for hanging multiple lightweight items; the material of the hook 7 is consistent with the main body of the storage box 100, using low-temperature resistant polypropylene (PP) or weather-resistant reinforced ABS plastic injection molding. This material maintains good toughness and dimensional stability within an ambient temperature range of -30℃ to 80℃, and is not prone to brittle cracking due to low winter temperatures or deformation due to high summer temperatures. Furthermore, the surface is matte-finished with a roughness Ra≤6.3μm, reducing sliding friction between the hook and the suspended items and preventing items such as keys and glasses from being worn due to shaking.

[0075] The installation position of hook 7 avoids the area of ​​screw mounting holes and wiring harness holes 4 at the bottom of storage box 100, ensuring that its structural integrity is not affected by the installation fixing point. In the assembled state, hook 7 extends towards the side of the vehicle or the edge of the berth, allowing users to naturally reach out to hang or remove items without getting up or leaning out when leaning against the berth, achieving the convenience of "easy to hang and easy to reach". The structure of hook 7 abandons the complex assembly methods of traditional bonding, riveting or metal stamping parts. Without adding extra parts or compromising the overall strength of the shell, the suspension function is achieved by one-piece molding. This reduces manufacturing costs and assembly processes, and avoids the problems of rust, scratches on interior or electromagnetic interference that may be caused by metal hooks. It is particularly suitable for the high humidity, dust and large temperature difference environment of commercial vehicle berth area, significantly improving the user's storage efficiency for small items and the tidiness of the space.

[0076] Optionally, the number of hooks 7 can be set according to the actual situation.

[0077] In another alternative embodiment, the bottom of the housing 101 near the vehicle has a continuously extending boss structure, and the hook 7 is fixed to the boss structure and isolated from the housing 101.

[0078] It should be further explained that the storage box 100 is a one-piece injection-molded structure. Its internal cavity, outer contour, flange structure 8, first limiting groove 61, wire harness hole 4, hook 7, and the cavity of each storage unit are all formed simultaneously through a single injection molding process. There are no secondary assembly, bonding, or mechanical fastening parts. The overall structure is seamless and has no screw connection points, which significantly improves the structural integrity and fatigue resistance. This integrated design not only simplifies the manufacturing process and reduces assembly costs, but also effectively avoids the failure risks such as loosening, abnormal noise, delamination, or breakage that may occur in multi-part combined structures under long-term vibration environment.

[0079] The storage box 100 is made of flame-retardant ABS engineering plastic (UL94V-0 rating). Its formula contains bromine or phosphorus flame retardants and improves heat distortion temperature and impact toughness through blending modification. The material maintains stable mechanical properties in an ambient temperature range of -30℃ to 85℃, with a flexural modulus of not less than 1800MPa and a cantilever beam impact strength of ≥40kJ / m². It can withstand the frequent handling and impact of items such as keys, lighters, water cups, and tables in daily use in the sleeper area. The ABS material surface is treated with anti-scratch coating, and the surface hardness reaches HB level (pencil hardness). It also has good UV aging resistance and will not yellow or lose its luster when exposed to direct sunlight in the cab for a long time, maintaining its appearance quality.

[0080] According to another aspect of the present invention, a vehicle is provided having a multi-functional storage device, which is the multi-functional storage device described above.

[0081] Specifically, such as Figure 2 As shown, the vehicle includes: a side panel 300, a sleeper berth 200, the sleeper berth 200 being connected to the side panel 300, and a multi-functional storage device located above the sleeper berth 200, with one side of the multi-functional storage device being connected to the side panel 300.

[0082] Specifically, the vehicle includes a side panel 300 and a sleeper berth 200 located inside the side panel 300. The sleeper berth 200 is rigidly connected to the inner wall of the side panel 300 via a metal bracket or an integrally formed structure, forming a resting platform fixed to the rear of the cab. A multi-functional storage device is installed in the upper area of ​​the sleeper berth 200, and its longitudinal projection completely covers the space above the end of the sleeper berth 200. In the vertical direction, the height of the bottom mounting surface of the multi-functional storage device from the upper surface of the sleeper berth 200 is 400mm to 500mm. This height range is determined based on the measured vertical height data of the 95th percentile of Chinese commercial vehicle drivers when their elbows are naturally hanging down in a seated position, ensuring that when users lean against the sleeper berth 200 to rest, their arms can be naturally placed flat on the surface of the multi-functional storage device without raising them. This allows for seamless operation of the magnetic suction device 5, USB port 3, first storage area 1, and third storage area 6. One side of the multi-functional storage device is fixedly connected to the inner wall surface of the side plate 300 via four mounting holes on the flange structure 8. During installation, screws pass through the through holes of the flange structure 8 and are screwed into the pre-embedded nuts on the side plate 300, or directly tapped into the sheet metal internal threads, forming a rigid coupling structure between the storage device and the side plate 300. This eliminates reliance on the berth 200 itself for load-bearing support, effectively preventing displacement, abnormal noise, or connection failure of the storage device due to deformation, loosening, or vertical vibration of the berth 200 during long-term use. The installation position of the multi-functional storage device is not directly connected to the berth 200. The supporting frame of the berth 200 directly interferes with the berth 200, and a clearance distance of 10mm to 20mm is maintained between it and the upper surface of the berth 200 to ensure that the berth 200 will not collide or be squeezed with the storage device when it is under load or when the angle is adjusted, thus maintaining the functional independence of the two. This arrangement ensures that the multi-functional storage device is always on the "static reference plane" at the rear of the cab - i.e., the side panel 300 - rather than linked with the berth 200, thereby ensuring that the positions of key functional units such as the magnetic suction device 5, the USB port 3, and the first limiting groove 61 are constant, ensuring that the user can accurately position the mobile phone holder, charging cable, and table every time they use it, forming a stable and predictable operating experience.

[0083] Meanwhile, since the multi-functional storage device is arranged close to the side panel 300, the rear area near the inner side of the compartment can naturally form a hidden channel for the wiring harness. The connection cable of the USB port 3 can be led down to the vehicle power system along the wiring harness inside the side panel 300, achieving concealed wiring, no exposure, and no tangling, improving the overall cleanliness and safety of the cab. This installation structure abandons unreliable methods such as pasting to the sleeper cover, snapping to the handrail, or suspending to the ceiling. It achieves stable fixation only through direct mechanical connection with the rigid side panel of the vehicle body, meeting the engineering requirements of high-intensity vibration, long service life, and high-reliability maintenance of commercial vehicles. It is a structural-level solution designed specifically for the use environment of the sleeper area of ​​commercial vehicles.

[0084] like Figure 5 As shown, the first storage area 1 is provided with a magnetic suction device 5, a USB port 3 and a second storage area 2 on the side near the vehicle side panel 300. The USB port 3 is located between the magnetic suction device 5 and the second storage area 2.

[0085] Specifically, along the longitudinal direction of the first storage area 1 near the vehicle side panel 300, a magnetic suction device 5, a USB port 3, and a second storage area 2 are arranged linearly, with independent spacing between them, forming a clear functional division and operating sequence. The magnetic suction device 5 is located at the outermost end of this side, and its magnetic area is a rectangular planar structure with dimensions of 30mm × 40mm. The surface is covered with a layer of wear-resistant nylon fabric to prevent the metal surface from scratching the phone holder and causing hard friction with the vehicle body. Its magnetic strength is calibrated to be no less than 0.3T, sufficient to stably attract mainstream commercially available magnetic phone holders (such as magnetic ring bases or magnetic clamp-type holders), ensuring that the phone will not fall off due to vibration even during severe bumps while the vehicle is in motion. A 15mm gap is maintained between the magnetic suction device 5 and the USB port 3. A center spacing of m to 20mm is provided to allow for finger operation, preventing accidental contact or obstruction of the USB port 3 when removing or placing the magnetic holder. This also prevents charging cables from becoming tangled in the magnetic area, causing adsorption failure. The USB port 3 is located in the middle between the magnetic device 5 and the second storage area 2. Its interface type is a Type-C or Micro-USB standard interface conforming to national standard GB / T20234.3. The installation depth is flush with the outer surface of the storage box 100. A dust cover made of flexible silicone is provided at the front of the interface, which automatically opens and closes with insertion and removal to prevent dust and debris from entering and causing poor contact. The electrical connection harness of the USB port 3 is led to the vehicle's power system through the harness hole 4. Its power output meets the QC3.0 or PD fast charging protocol, with a maximum output current of not less than 2 kW.4A, simultaneously supporting fast charging for mainstream smartphones and low-power charging for tablets; a 10mm to 15mm gap is set between the USB port 3 and the second storage area 2 to ensure that after the user unplugs the charging cable from the USB port 3, the cable end can naturally hang below the storage box 100 without interfering with the opening edge of the second storage area 2, preventing the data cable from being squeezed or bent and damaged; the second storage area 2 is located next to the USB port 3, with its opening facing diagonally upward, making it easy for users to reach in with one hand to put in and take out small items such as lighters, earphones, and foldable charging heads. Its position is slightly lower than the magnetic device 5 and the USB port 3, so that the three form a visual and tactile guiding sequence from high to low, which conforms to the user's natural flow from "phone attachment - charging connection - storage of small items". Operational sequence: This linear arrangement has been verified through simulation tests with 50 commercial vehicle drivers. 92% of users, without visual confirmation, can complete the continuous actions of "attaching the phone to the magnetic device 5—inserting the charging cable to the USB port 3—retrieving the lighter" within 3 seconds using muscle memory, significantly improving efficiency and user experience in the sleeper area. This layout does not employ complex corner, staggered, or rotating structures; it achieves functional synergy solely through horizontal linear arrangement. It is compact, simple to manufacture, and reliably assembled, and highly compatible with the overall spatial form of the sleeper area. This allows the storage box 100 to simultaneously meet the three high-frequency needs of "attachment—charging—storage" within a limited installation space, achieving optimal integration of functional density and human-machine efficiency.

[0086] The technical solution of this application has the following effects:

[0087] This multi-functional storage device integrates storage space for mobile phones and their charging cables, a water cup holder, a USB port, and quick-connect fixing interfaces for most mobile phone holders, car tables, or bars on the market, as well as storage space for personal belongings. It provides users with storage space for mobile phones in the sleeper area, charging mobile phones while storing them, storing water cups, using mobile phones while drinking water, using mobile phones with a self-purchased magnetic mobile phone holder, using mobile phones with a self-purchased clamp-on mobile phone holder, temporary office work, eating light meals, and using mobile phones while eating. It greatly facilitates users' leisure and entertainment life in the sleeper area, allowing them to enjoy maximum physical and mental relaxation with the lowest cost investment.

[0088] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features.
