[0081] Combination Figures 1 to 15 As shown, according to a specific embodiment of this application, a cargo carrier assembly is provided.

[0082] This application provides a cargo-carrying component, such as... Figure 1 As shown, the assembly includes a support assembly 100 and a tabletop assembly 200. The top of the support assembly 100 has a working surface. The tabletop assembly 200 includes at least one rotating tabletop assembly and at least one sliding tabletop assembly. The rotating tabletop assembly is rotatably connected to the support assembly 100 so that the rotating tabletop assembly has a first storage position stored on one side of the support assembly 100 and a first unfolded position when unfolded. The sliding tabletop assembly is movably connected to the rotating tabletop assembly so that at least a portion of the sliding tabletop assembly has a second storage position stored within the rotating tabletop assembly and at least a portion of the sliding tabletop assembly has a second unfolded position that slides out from within the rotating tabletop assembly. When the rotating tabletop assembly is in the first unfolded position and the sliding tabletop assembly is in the second unfolded position, at least one of the planes containing the working surfaces of the rotating tabletop assembly and the sliding tabletop assembly is parallel to the working surface of the support assembly 100.

[0083] The embodiments of this application achieve the following technical effects: The table assembly 200, integrated within the cargo-carrying component, enables the unfolding and folding of the table. The table assembly 200 comprises at least one rotating table assembly and at least one sliding table assembly. The rotating table assembly is rotatably connected to the support assembly 100, allowing the table to switch between a first stowage position and a first unfolded position, thus opening and closing the table. The sliding table assembly and the rotating table assembly are movably connected, allowing them to switch between a second stowage position and a second unfolded position. Through the combination of the sliding and rotating table assemblies, this invention provides a large-size table surface within a limited space, meeting the needs of passengers in different scenarios. Furthermore, it can be folded away when not in use, maximizing space saving. This application solves the technical problems of existing automotive cabin tables being unable to open and close, and having limited table sizes.

[0084] Optionally, at least one of the planes containing the working surfaces of the rotating table assembly and the sliding table assembly is parallel to the working surface of the support assembly. This provides a stable platform, preventing items from slipping or tipping over during use, especially in the cabin environment while the vehicle is in motion. This significantly improves the safety of the table and passenger comfort. When both the rotating and sliding tables are unfolded, their working surfaces remain parallel to the working surface of the support assembly, forming a continuous plane across the entire table. Passengers can use either the rotating or sliding table on the same horizontal plane, avoiding the inconvenience caused by uneven surfaces.

[0085] Example 1

[0086] Specifically, the rotating tabletop assembly comprises multiple sets, arranged circumferentially along the working surface of the support assembly 100. Each rotating tabletop assembly includes at least one set of sliding tabletop components. When the rotating tabletop assemblies are in the first unfolded position, a clearance area is formed between adjacent rotating tabletop assemblies. When the sliding tabletop assemblies are in the second unfolded position, at least some of the sliding tabletop components are positioned between adjacent rotating tabletop assemblies, filling the clearance area. By using multiple sets of rotating tabletop assemblies, a larger desktop area can be provided to meet different usage needs.

[0087] The clearance area is necessary when the table assembly is in the retracted state to ensure that the rotating table components can smoothly switch from the first unfolded position to the first retracted position without interfering with each other.

[0088] Each sliding table assembly is designed such that, when in the second unfolded position, at least a portion of the sliding table assembly can slide out from the rotating table assembly and fill the clearance area between adjacent rotating table assemblies. This means that when all rotating and sliding table assemblies are fully unfolded, the working surface of the table assembly becomes continuous and complete, eliminating wasted space due to clearance areas and providing a larger, more practical working surface.

[0089] In this embodiment, as Figure 2 As shown, the rotating table assembly is set into 3 groups. The 3 groups of rotating table assemblies are arranged adjacent to each other along the circumference of the working surface of the support assembly 100. Among them, two groups of rotating table assemblies are arranged opposite each other along the working surface of the support assembly 100. The working surface sizes of the 3 groups of rotating table assemblies are set differently.

[0090] Specifically, multiple sets of rotating tabletop assemblies can be arranged to rotate synchronously, or multiple sets of rotating tabletop assemblies can be arranged to rotate independently. The synchronous rotation design ensures the neatness and consistency of the tabletops when unfolded, while independent rotation provides greater flexibility, allowing each set of rotating tabletop assemblies to be controlled individually according to actual needs, thus meeting different user requirements.

[0091] Synchronous rotation means that all rotating table components unfold or retract together, forming a coordinated and consistent operation. This simplifies table control and operation; passengers can control all rotating table components with a single button, eliminating the need for individual operation and improving ease of use. Independent rotation allows passengers to selectively unfold or retract specific rotating table components according to their individual needs. This means passengers can open only the portions they need, saving space or adapting to different usage scenarios. If a group of rotating table components malfunctions, independent rotation allows for repair or replacement of only that component without affecting the normal operation of other table components, reducing the risk of the entire table system failing due to a partial malfunction.

[0092] Specifically, during the process of moving the sliding table assembly from the second retracted position to the second unfolded position, the sliding table assembly can drive the rotating table assembly to rotate from the first retracted position to the first unfolded position. There is a mechanical linkage mechanism between the sliding table assembly and the rotating table assembly, typically achieved through a pre-set slide rail and roller structure, as well as internal linkages or transmission devices. When the sliding table assembly begins to slide outward from the retracted space inside the rotating table assembly, its own movement drives the rotating table assembly to rotate around the axis of rotation via the linkage or transmission mechanism. This linkage design eliminates the need for passengers to manually rotate the rotating table assembly; when the passenger operates the sliding table assembly, the rotating table assembly automatically unfolds, simplifying the operation process and improving the user experience. This design, where the sliding table assembly drives the unfolding of the rotating table assembly, makes the table assembly structure more integrated.

[0093] Specifically, at least one of the multiple sets of rotating tabletop assemblies is provided with two sliding tabletop assemblies. The two sliding tabletop assemblies include a first sliding tabletop assembly and a second sliding tabletop assembly. The first sliding tabletop assembly is movably disposed in the first end of the rotating tabletop assembly, and the second sliding tabletop assembly is movably disposed in the second end of the rotating tabletop assembly. The sliding tabletop assembly of the rotating tabletop assembly adjacent to the first end of the first sliding tabletop assembly is hinged to the first sliding tabletop assembly, and the sliding tabletop assembly of the rotating tabletop assembly adjacent to the second end of the second sliding tabletop assembly is hinged to the second sliding tabletop assembly.

[0094] The first sliding table assembly is movably disposed within the first end of the rotating table assembly, while the second sliding table assembly is movably disposed within the opposite second end of the rotating table assembly. This layout design ensures that the table assembly can extend in both directions when unfolded, maximizing the use of the cabin's lateral space, embedding the sliding table assembly within the rotating table assembly, and also allows the table assembly to be compactly stored when not in use, avoiding taking up too much space.

[0095] The sliding tabletop assembly adjacent to the first sliding tabletop assembly is connected to the rotating tabletop assembly via a hinge, and similarly, the sliding tabletop assembly adjacent to the second sliding tabletop assembly is also connected to it via a hinge. This hinged design aims to ensure that during operation, movement of any sliding tabletop assembly triggers the synchronous unfolding of the sliding tabletop assemblies of adjacent rotating tabletop assemblies. Due to the hinged connection, the unfolding of the first sliding tabletop assembly not only allows it to slide completely out of the rotating tabletop assembly but also, through the linkage effect at the hinge point, causes the sliding tabletop assemblies on the adjacent rotating tabletop assembly to also begin unfolding. Similarly, the unfolding of the second sliding tabletop assembly also drives the unfolding of its adjacent sliding tabletop assemblies. Through this hinged and linkage mechanism, the tabletop assembly, when fully unfolded, forms a continuous and wide working surface.

[0096] Specifically, when the first and second sliding tabletop assemblies are in the second unfolded position, their working surfaces are both parallel to the working surfaces of the adjacent sliding tabletop assemblies. This design ensures that the tabletops form a flat, continuous plane when unfolded, facilitating the placement of items.

[0097] Specifically, such as Figure 3 As shown, the rotating table assembly includes: a first rotating table 201, which has at least one receiving cavity. The first rotating table 201 is movably connected to the support assembly 100 via a first rotating shaft 105. At least one first guide rail 2011 is provided within the receiving cavity. A sliding table assembly is movably disposed within the receiving cavity and can move along the first guide rail 2011 to a second stowed position and a second unfolded position. The first rotating table 201 can rotate around the first rotating shaft 105 to the first stowed position and the first unfolded position. The internal receiving cavity and guide rail design of the rotating table assembly provide a stable movement trajectory for the sliding table assembly and also provide space for the table to be stowed. The first rotating table 201 is connected to the support assembly 100 via the first rotating shaft 105, enabling rotation. The sliding table assembly slides within the rotating table assembly via the first guide rail 2011. This combined movement mechanism allows the table to be unfolded and stowed without occupying additional space.

[0098] It should be further explained that in this embodiment, there are three sets of rotating table assemblies, corresponding to the first rotating table 201, the second rotating table 204, and the third rotating table 207, respectively. The first rotating table 201 and the third rotating table 207 are arranged opposite each other along the working surface of the support assembly 100. The second rotating table 204 is arranged adjacent to the first rotating table 201 and the third rotating table 207, respectively. The first rotating table 201 and the third rotating table 207 are movably connected to the support assembly 100 through the first rotating shaft 105. The second rotating table 204 is movably connected to the support assembly 100 through the second rotating shaft 104. The axis of the first rotating shaft and the axis of the second rotating shaft are arranged perpendicular to each other.

[0099] In this embodiment, the first rotating table 201 and the third rotating table 207 are provided with one receiving cavity, and the second rotating table 204 is provided with two receiving cavities. This design allows the sliding table assembly to be hidden inside the rotating table when not in use, greatly saving cabin space. The presence of the receiving cavities also provides protection for the sliding table assembly, preventing damage or interference when not in use. When a passenger needs to use the table, they can first operate the sliding table assembly to move from the second storage position to the second unfolded position. This action will trigger the first rotating table 201 and the third rotating table 207 to rotate around the first rotation axis 105 from the first storage position to the first unfolded position, and the second rotating table 204 to rotate around the second rotation axis 104 from the first storage position to the first unfolded position. Conversely, when the table is not needed, the sliding table assembly can move back to the second storage position along the first guide rail 2011, and then the rotating table assembly automatically returns to the first storage position, completing the entire table system's folding process.

[0100] Specifically, there are one or more first guide rails 2011, which can be linear or curved. The choice between linear and curved guide rails affects the movement path of the sliding table assembly, thus influencing the table's unfolding effect. Linear guide rails allow the sliding table assembly to slide along a straight line, while curved guide rails allow it to move along a curved path. This differentiated guide rail design can meet different usage requirements.

[0101] In this embodiment, each receiving cavity is provided with three first guide rails 2011, and the three first guide rails 2011 are spaced apart as arc-shaped guide rails. The circles containing the three arc-shaped guide rails are concentric, meaning that their centers are located at the same position. This design ensures the consistency and stability of the sliding table assembly during unfolding and folding. The center position of the arc-shaped guide rail can be selected at the apex of the rotating table and the sliding plate, or the designer can choose other suitable positions according to the geometry of the table and the movement requirements.

[0102] The curvature of the curved sliding rail allows for precise control of the skateboard's movement path, reducing vibration and noise during operation and enhancing the passenger experience. Compared to straight sliding rails, curved sliding rails can save space more effectively in certain situations. This is because curved sliding rails create a more compact movement path within the rotating table, resulting in a smaller footprint for the skateboard when stored, thus maximizing space utilization.

[0103] Optionally, the first sliding plate 202 and the second sliding plate 203 are hinged together adjacent to each other. The first sliding plate 202 can be stored in the receiving cavity of the first rotating table 201, and the second sliding plate 203 can be stored in the receiving cavity of the second rotating table 204. The first guide rails 2011 in the second rotating table 204 and the first rotating table 201 are staggered. The staggered rotating guide rail design ensures that the first sliding plate 202 and the second sliding plate 203 can move independently and smoothly during the unfolding and retraction process, eliminating possible mechanical interference, making the operation of the entire table system smoother, and improving the passenger's user experience.

[0104] Specifically, the sliding table assembly includes: a first slide plate 202, on the surface of the first slide plate 202 facing the first guide rail 2011, a first roller 2012 that cooperates with the first guide rail 2011 is provided, and a connecting structure is provided on the side of the first slide plate 202 away from the first roller 2012.

[0105] like Figure 4 As shown, the surface of the first sliding plate 202 facing the first guide rail 2011 is provided with first rollers 2012, which closely cooperate with the first guide rail 2011 inside the second rotating table 204. The first rollers 2012 can roll along the track of the guide rail, guiding the movement direction of the first sliding plate 202 when unfolding and retracting, ensuring smoothness and stability during movement. On the side of the first sliding plate 202 away from the first rollers 2012, a special connection structure is designed. This connection structure is mainly used for docking with the electric strut or other transmission components. Through this connection point, the electric strut can drive the first sliding plate 202 to unfold or retract along the direction of the first guide rail 2011, realizing the opening and closing function of the table. Utilizing the rolling contact between the first rollers 2012 and the first guide rail 2011, precise positioning of the sliding plate assembly can be achieved and wear during movement can be reduced. Compared with sliding contact, rolling contact can significantly reduce friction and extend the service life of various components of the table system.

[0106] like Figure 5As shown, both ends of the second rotating table 204 are provided with receiving cavities for storing the second sliding plate 203 and the third sliding plate 205. In this embodiment, the three starting points of the three spaced-apart first guide rails 2011 are preferably not on the same straight line. This is because when the sliding plate unfolds or retracts along the arc guide rail, if the starting points of the first guide rails corresponding to the three rollers are on the same straight line, the weight of the table may be concentrated in that straight area, leading to excessive local stress and potentially causing excessive wear of the guide rails or rollers, reducing the stability and service life of the table system. Distributing the three starting points at different locations, especially when the table is unfolded, can evenly distribute the weight of the table on different parts of the guide rails, enhancing the structural stability of the entire table assembly and improving its load-bearing capacity. The three non-collinear arc guide rail starting points can form a triangular support system. Compared to the case of three points being collinear, this layout can significantly enhance the rigidity of the table assembly and reduce deformation under stress, which is crucial for improving the load-bearing capacity and extending the service life of the table.

[0107] In another specific embodiment, the starting point of the first guide rail 2011 can protrude beyond the outer edge of its corresponding rotating table, or the starting point of the first guide rail 2011 can be located inside the outer edge of its corresponding rotating table. When the starting point of the first guide rail 2011 is designed to protrude beyond the outer edge of the rotating table, it means that the starting part of the guide rail is not in the plane of the corresponding rotating table, but extends outward. This provides a smoother movement path for the corresponding skateboard when the rotating table is unfolded. When the starting point of the first guide rail 2011 is located inside the outer edge of its corresponding rotating table, the skateboard is more compact in the folded state and does not occupy extra space.

[0108] It should be further explained that, in this embodiment, as Figure 6 As shown, four sets of sliding components are provided, each of which is respectively provided with a first sliding plate 202, a second sliding plate 203, a third sliding plate 205, and a fourth sliding plate 206. The structures of the first sliding plate 202, the second sliding plate 203, the third sliding plate 205, and the fourth sliding plate 206 are identical. The first sliding plate 202 is arranged adjacent to the second sliding plate 203, and the third sliding plate 205 is arranged adjacent to the fourth sliding plate 206. The first sliding plate 202 can be stored in the receiving cavity of the first rotating table 201. The second sliding plate 203 and the third sliding plate 205 are respectively stored in the receiving cavities at both ends of the second rotating table 204. The fourth sliding plate 206 can be stored in the receiving cavity of the third rotating table 207.

[0109] Example 2

[0110] Specifically, the carrying assembly also includes a support rod assembly 102, with a first end connected to the support assembly 100 and a second end connected to at least one sliding table assembly. The support rod assembly 102 drives the sliding table assembly to move to a second stowed position and a second unfolded position, thereby causing the sliding table assembly to rotate the rotating table assembly to the first stowed position and the second stowed position. The design of the support rod assembly provides a power source for the unfolding and stowing of the sliding table assembly. The support rod assembly 102, through its telescopic movement, pushes or pulls the sliding table assembly, thereby triggering the rotation of the rotating table assembly.

[0111] Optionally, the second end of the strut assembly 102 is connected to at least one sliding tabletop assembly. This connection point is typically located at a specific position on the tabletop assembly, allowing the strut to directly act on the sliding tabletop assembly, driving it to move along the first guide rail 2011 or the arc-shaped slide rail. While driving the sliding tabletop assembly, the strut assembly 102 can also indirectly affect the rotation of the rotating tabletop assembly. When the sliding tabletop assemblies move along the guide rail to a designated position, their weight distribution changes are transmitted to the rotating tabletop assembly through the connection point, causing the rotating tabletop to automatically adjust to the first stowed position or the second unfolded position according to the state of the sliding tabletop, thus realizing the intelligent opening and closing function of the tabletop system.

[0112] It should be further explained that the connection points between the strut assembly 102 and the support assembly 100, and the connection points between the second end of the strut assembly 102 and the first sliding plate 202 and the second sliding plate 203, are located on the central plane of symmetry of the sliding table assembly. This design ensures the symmetry of movement during the unfolding and folding of the table. Whether the table moves to the left or right, or is lifted up or down, the movement of the table will be along the central plane of symmetry, avoiding movement deviation or imbalance caused by asymmetry of the connection points. The centrally symmetrical hinge design also helps to evenly distribute the load on the table. When heavy objects are placed on the table, if the hinge points are not on the central plane of symmetry, the table may twist or tilt due to uneven load distribution, affecting the user's comfort and safety.

[0113] Optionally, when the connection point between the strut assembly 102 and the first slide plate 202 and the second slide plate 203 is located at the outermost end of the corresponding slide plate on the side furthest from the first conductive silicon, this design fully utilizes the lever principle in mechanics. The length of the slide plate can be considered as the arm length of the lever, with the connection point as the fulcrum. The thrust or pull force of the strut assembly is maximized and converted into the unfolding or retracting force of the tabletop through the lever effect, thereby improving the load-bearing capacity of the slide plate. This is because most of the area of ​​the slide plate is located at the far end of the connection point, which can better support and distribute the weight of the items placed on it.

[0114] The connection point between the strut assembly 102 and the corresponding slide plate and support assembly 100 can be changed according to the actual situation.

[0115] Specifically, the strut assembly 102 is located on the outside of the support assembly 100. When the sliding table assembly moves to the second storage position, the axis of the strut assembly 102 is arranged along the height direction of the support assembly 100. Alternatively, the strut assembly 102 is located inside the support assembly 100. When the sliding table assembly moves to the second storage position, at least a portion of the strut assembly 102 is stored inside the support assembly 100.

[0116] Optionally, in one embodiment, the strut assembly 102 is fixed to the outside of the support assembly 100. When the sliding table assemblies (such as the first slide plate 202 and the second slide plate 203) are in the second retracted position, that is, when they are completely retracted into the rotating table assembly, the axis of the strut assembly 102 is aligned along the height direction of the support assembly 100. This means that the strut assembly is in a compressed or extended state, but its main part is still located outside the housing. That is, when the passenger presses the table opening command, the strut assembly 102 begins to extend, connecting with the sliding table assembly through the hinge point, and gradually pushing it out of the rotating table assembly to the second unfolded position. At the same time, the rotating table assembly rotates and unfolds around the pivot, forming a complete tabletop. When the passenger wishes to close the table, the strut assembly 102 retracts, pushing the sliding table assembly to move in the opposite direction until it is completely retracted into the cavity of the rotating table assembly. At this time, the axis of the strut assembly 102 is aligned again along the height direction of the support assembly 100, and the sliding table assembly enters the second retracted position.

[0117] Alternatively, in another embodiment, part or all of the strut assembly 102 is housed inside the support assembly 100. This typically means that the strut assembly 102 can be hidden inside the housing when the table is in the second storage position, reducing the impact on the appearance and protecting the strut assembly from damage by external factors.

[0118] External strut assemblies offer advantages such as simple structure, intuitive operation, and unrestricted extension / retraction within the cabin, facilitating longer tabletop deployment distances and larger tabletop sizes. However, this can also result in a larger cabin space footprint when the tabletop is closed. Internal strut assemblies, on the other hand, maximize cabin space efficiency. When the tabletop assembly is in its second storage position, the struts can be completely or partially concealed within the cabin, improving space utilization. However, this may limit the strut's extension / retraction range and the tabletop's deployment area, factors that need to be carefully considered during the design phase.

[0119] Specifically, each of the two adjacent sliding tabletop assemblies is provided with a support rod assembly 102, and the support rod assembly 102 is connected to the hinge of the adjacent sliding tabletop assembly.

[0120] In this embodiment, the first slide plate 202 and the second slide plate 203 are controlled by a strut assembly 102, and the third slide plate 205 and the fourth slide plate 206 are also controlled by a strut assembly. Both sides can be driven simultaneously or controlled individually. When driven synchronously, the hinge points of the two strut assemblies with the first slide plate 202 and the second slide plate 203, the third slide plate 205 and the fourth slide plate 206 are preferably symmetrical and move at the same speed.

[0121] The strut assembly 102 can be driven by various methods such as electric drive or pneumatic drive. In this embodiment, the strut assembly 102 can be driven by a cylinder rod to extend and retract, thereby driving the sliding table assembly to move to the second storage position and the second unfolded position.

[0122] Example 3

[0123] Specifically, such as Figure 1 , Figure 7 As shown, the carrying assembly also includes a base assembly 300, which includes: a base 301, within which at least a portion of the support assembly 100 is disposed; and a lifting mechanism 310, also within the base 301, with at least a portion of the lifting mechanism 310 located at the bottom of the support assembly 100. The lifting mechanism 310 drives the support assembly 100 to move vertically to a target height, thereby causing the support assembly 100 to synchronously move the tabletop assembly 200 vertically. The design of the lifting mechanism 310 allows for height adjustment of the support assembly 100 to meet the needs of different users. The lifting mechanism 310 transmits power to the support assembly via a power source and transmission mechanism, enabling it to move vertically and easily adjust the tabletop height.

[0124] The base 301 is the basic structure of the entire table system. It houses part or all of the support assembly 100 and the lifting mechanism 310. The design of the base 301 must not only consider sufficient strength to support the table system, but also have enough space to accommodate the support assembly 100 and the lifting mechanism 310, while ensuring good sealing to isolate the interior and exterior environments of the carriage and protect the internal components from damage.

[0125] Specifically, such as Figure 8 , Figure 9As shown, the lifting mechanism 310 includes: a power source 312, a transmission mechanism 314, and at least one lifting bracket 316. The power source 312 is connected to the base 301 and has an output shaft 313. The transmission mechanism 314 is disposed within the base 301, and one end of the transmission mechanism 314 is connected to the output shaft 313. The lifting bracket 316 is disposed within the base 301 and is connected to the other end of the transmission mechanism 314. The lifting bracket 316 is connected to the support assembly 100. The power source 312 can drive the transmission mechanism 314 to move the lifting bracket 316, so that the lifting bracket 316 moves the support assembly 100 vertically to the target height position.

[0126] The power source 312 is the core component of the lifting mechanism. It typically consists of an electric drive motor, providing the driving force required to move the tabletop assembly 200 vertically. The motor is fixedly connected to the base 301, ensuring the stability and reliability of power transmission. The output shaft 313 converts the rotational power of the motor and transmits it to the transmission mechanism 314, thus affecting the entire tabletop height adjustment process. The transmission mechanism 314 acts as a bridge between the power source and the lifting bracket. One end of it is connected to the output shaft 313, and the other end is connected to the lifting bracket 316. In this invention, the transmission mechanism 314 can be a lead screw, rack and pinion, or chain drive, etc.

[0127] In this embodiment, two lifting brackets 316 are provided. The two lifting brackets 316 are arranged opposite each other along the length direction of the base 301. They are evenly distributed and jointly bear the weight of the table.

[0128] Specifically, such as Figure 10 As shown, the transmission mechanism 314 includes: a lead screw body, the first end of which is connected to the output shaft 313; a first external thread 3141 and a second external thread 3142 are provided between the first end and the second end of the lead screw body, the threads of the first external thread 3141 and the second external thread 3142 are arranged in opposite directions, and each of the first external thread 3141 area and the second external thread 3142 area of ​​the lead screw body is provided with a lead screw roller 315, the lead screw roller 315 is movably connected to the base 301, and the lifting bracket 316 is connected to each lead screw roller 315. The rotation of the lead screw body, through the engagement of the first external thread and the second external thread with the lead screw roller, generates a thrust or pull force, enabling the lifting bracket to move in the vertical direction.

[0129] The lead screw body, as part of the transmission mechanism 314, is connected to the output shaft 313 of the power source 312 via its first end. It is responsible for converting the rotational motion of the electric motor into linear motion, thereby achieving the lifting and lowering of the tabletop. On the lead screw body, a first external thread 3141 and a second external thread 3142 are sequentially provided from the first end to the second end. The most significant characteristic of these two thread sections is that their thread directions are opposite. This means that when the lead screw body rotates, the lead screw rollers 315 connected to these two thread sections will move in opposite directions. The lead screw rollers 315 are rollers with internal threads, respectively located in the first external thread 3141 area and the second external thread 3142 area of ​​the lead screw body. Each roller engages with the corresponding external thread through its internal thread, thus enabling it to move linearly along the threads on the lead screw body according to the rotation direction of the lead screw body.

[0130] Specifically, the end of the output shaft 313 is a worm gear structure, and the first end of the lead screw body is equipped with a worm wheel 3143 that mates with the worm gear structure. The purpose of designing the end of the output shaft 313 as a worm gear structure is to convert the high-speed rotation of the power source 312 (usually a motor) into a low-speed, high-torque output. Due to its helical tooth design, the worm gear can provide a large reduction ratio, making it suitable for the up-and-down movement of the lifting bracket 316, which requires a large torque drive. The worm gear structure typically has good self-locking characteristics, meaning that when the worm is stationary, it is difficult for the worm wheel 3143 to reverse the rotation of the worm. This is very useful in the height locking of the tabletop system, preventing the tabletop from accidentally moving due to slight external vibrations during use, thus ensuring the stability and safety of the tabletop.

[0131] A worm gear 3143 is provided at the first end of the lead screw body. The tooth profile of the worm gear matches the helical teeth of the worm, forming a worm gear transmission pair. In this invention, the worm gear 3143 is fixed to the lead screw body, which is connected to the lifting bracket 316. Therefore, the rotation of the worm gear 3143 is directly converted into the linear motion of the lead screw. When the power source 312 is started, the output shaft 313 rotates accordingly, and the worm structure drives the worm gear 3143, which meshes with it, to rotate. Since the worm gear 3143 is fixedly connected to the lead screw body, the rotation of the worm gear causes the lead screw body to move along its axial direction (i.e., linear motion). This motion of the lead screw can be converted into the vertical lifting and lowering of the lifting bracket 316, thereby driving the entire support assembly 100 and the table assembly 200 to move vertically, realizing the adjustment of the table height.

[0132] Specifically, such as Figure 8 , Figure 9 , Figure 12As shown, the lifting bracket 316 includes: a first bracket 3161, with a first rotating roller 318 at its first end, movably connected to the support assembly 100 via the first rotating roller 318, and a second end movably connected to the base 301 via one of the lead screw rollers 315; and a second bracket 3162, hinged to the middle of the first bracket 3161, with a second rotating roller 320 at its first end, movably connected to the support assembly 100 via the second rotating roller 320, and a second end movably connected to the base 301 via another lead screw roller 315. When the lead screw roller moves along the lead screw body, the first and second brackets unfold or retract through the hinge point, thereby driving the support assembly to move vertically.

[0133] Optionally, the first bracket 3161 and the second bracket 3162 are connected at the middle via a hinge point, forming an "X"-shaped structure. This design allows the two brackets to change their angle as the lead screw roller 315 moves along the transmission mechanism 314, thereby affecting the lifting or lowering of the table assembly 200. When the lifting mechanism is working, it drives the transmission mechanism 314 to rotate via the output shaft 313. The lead screw roller 315 engages with the thread of the transmission mechanism 314, with one lead screw roller 315 moving along the front half of the lead screw and the other along the rear half. Since the two sections of the thread of the transmission mechanism 314 are in opposite directions, the two lead screw rollers 315 also move in opposite directions. When the two lead screw rollers 315 move towards each other, the hinge point of the first bracket 3161 and the second bracket 3162 will move closer to the center, increasing the angle between the two brackets, thereby pushing the lifting bracket 316 upward as a whole, ultimately raising the support assembly 100 and the table assembly 200. Conversely, when the two lead screw rollers 315 move in opposite directions, the hinge point of the first bracket 3161 and the second bracket 3162 will spread outward, and the angle formed by the two brackets will become smaller, thereby driving the lifting bracket 316 to move downward as a whole, realizing the lowering of the table assembly 200.

[0134] In this embodiment, the first rotating roller 318 and the second rotating roller 320 have the same structure.

[0135] Specifically, such as Figure 8 , Figure 13As shown, a first guide groove 317 and a second guide groove 319 are provided in the base 301. The first guide groove 317 and the second guide groove 319 are provided at intervals along the height direction of the base 301. The length direction of the first guide groove 317 and the second guide groove 319 extends along the width or length direction of the base 301. The lead screw roller 315 is movably disposed in the first guide groove 317, and the first rotating shaft roller 318 and the second rotating shaft roller 320 are movably disposed in the second guide groove 319.

[0136] In this embodiment, the first guide groove 317 and the second guide groove 319 have the same structural configuration. The lead screw roller 315 is designed to roll freely within the first guide groove 317 in the base 301, but its lateral movement in the plane is restricted. This design ensures that the roller can only move along the length direction of the first guide groove 317 without lateral deviation, thereby ensuring that the lifting bracket 316 connected to the roller rises or falls stably in the vertical direction under guidance. The first rotating shaft roller 318 and the second rotating shaft roller 320 are respectively disposed in the second guide groove 319 of the base 301, and are similarly constrained by the groove, only able to roll along the length direction of the groove, and cannot move laterally.

[0137] like Figure 14 , Figure 15 The diagram shown is a schematic of the cargo-carrying assembly before and after lifting. The working principle of the cargo-carrying assembly lifting is as follows:

[0138] Tabletop Lifting Process: The user selects to raise the tabletop via an interface (such as a touchscreen or physical buttons). Upon receiving the signal, the control unit activates the power source 312, driving the motor to start working. The output shaft 313 rotates with the motor, and its end worm gear structure drives the worm wheel 3143 on the lead screw body to rotate. As the lead screw body begins to rotate, due to the opposite orientation of the first external thread 3141 and the second external thread 3142, the two lead screw rollers 315 begin to move towards each other along the first guide groove 317, reducing the distance between them. As the two lead screw rollers 315 move towards each other, the "X"-shaped mechanism of the lifting bracket 316 gradually retracts. During this process, due to the cooperation of the first rotating shaft roller 318 and the second rotating shaft roller 320 with the second guide groove 319, the first ends of the first bracket 3161 and the second bracket 3162 move upwards, thereby driving the support assembly 100 and the tabletop assembly 200 to rise vertically to the target height.

[0139] Tabletop descent process: The user issues a command to lower the tabletop. The control unit correspondingly reverses the drive of the power source 312. The output shaft 313 rotates in the opposite direction, causing the lead screw body to rotate in the opposite direction. The reverse rotation of the lead screw body causes the lead screw rollers 315 to move in opposite directions, that is, the two lead screw rollers 315 move in opposite directions. The "X"-shaped structure of the lifting bracket 316 retracts accordingly, and the first ends of the first bracket 3161 and the second bracket 3162 slide downward, thereby driving the entire system to descend until it reaches the height set by the user.

[0140] Specifically, the support assembly 100 includes a support body 101, the top of which forms the working surface of the support assembly 100. When the rotating table assembly is in the first storage position, the rotating table assembly is fitted against the side wall of the support body 101.

[0141] The support body 101 forms the main frame of the tabletop, providing structural support and internal space to accommodate the various components of the tabletop when folded. The top of the support body 101 forms the working surface of the tabletop assembly, i.e., the plane on which passengers can place items when the tabletop is unfolded.

[0142] In this embodiment, as Figure 1 As shown, when the rotating table assembly is in the first storage position, it means that the table is in a folded state. At this time, each rotating table is set in close contact with the side wall of the support body 101, so that the entire table system can be compactly stored in the space of the cabin center console without occupying additional passenger activity space.

[0143] Specifically, the support assembly 100 includes a fixed bracket 103, which is fixedly connected to the bottom of the support body 101, and a second guide groove 319 is fixedly connected to the fixed bracket 103. The design of the fixed bracket provides stable support for the support assembly. The fixed bracket is connected to the bottom of the housing and fixed to the second guide groove, ensuring the stability of the lifting mechanism when driving the support assembly to move.

[0144] The second guide groove 319 is located between the base 301 and the fixed bracket 103, and its function is to provide a precise sliding path for the first rotating roller 318 and the second rotating roller 320. The length of the guide groove extends along the width or length of the base 301 to ensure that the rollers can move smoothly along a straight line.

[0145] Specifically, the base assembly 300 includes: a central control box bracket 311, which is disposed inside the base 301 and is fixedly connected to the base 301; and a power source 312 is fixedly connected to the central control box bracket 311.

[0146] The central control box bracket 311 is cleverly designed and housed inside the base 301. It is tightly connected to the base 301 structure via welding, bolting, or other reliable fixing methods. The shape and dimensions of the central control box bracket 311 need to match the internal space of the base 301, while providing a fixed mounting position for the power source. Users will not feel vibration or movement of the power source when operating the table, improving user comfort.

[0147] Specifically, such as Figure 11 As shown, the lead screw roller 315 includes: a connecting block 3151, which has a threaded hole 3152 that mates with a first external thread 3141 or a second external thread 3142, and is connected to the lead screw body through the threaded hole 3152; and a roller 3153, which is movably connected to the connecting block 3151 and is rotatably arranged relative to the connecting block 3151. The rotation axis of the roller 3153 is perpendicular to the axis of the lead screw body, and the roller 3153 is movably connected to the base 301.

[0148] The threaded hole 3152 is located at the center of the connecting block 3151, and its internal thread matches the first external thread 3141 or the second external thread 3142 on the lead screw body to form a threaded pair. When the lead screw body rotates under electric drive, the connecting block 3151 will move along the axial direction of the lead screw body. This movement is achieved by the helical motion of the threaded pair, which ensures the accuracy and stability of the movement.

[0149] The rotation axis of roller 3153 is set perpendicular to the axis of the lead screw body, which means that the rotation direction of the roller is independent of the rotation direction of the lead screw. This perpendicular setting ensures that the rolling of the roller during the axial movement of the lead screw body is not disturbed by the rotation of the lead screw, thus maintaining the smooth rolling of the roller and the linear motion of the lead screw body.

[0150] The lead screw roller 315 and the base 301 are movably connected through the rolling contact between the roller 3153 and the first guide groove 317. Driven by the axial movement of the lead screw body, the roller 3153 rolls along the guide groove, thereby ensuring the stability and straightness of the lifting bracket 316 during the height adjustment process.

[0151] Specifically, the rotating table assembly rotates at a right angle from the first storage position to the first unfolded position. This right-angle rotation design ensures that the rotating table assembly remains parallel to the working surface of the support assembly when unfolded, improving the table's usability.

[0152] According to another aspect of the embodiments of this application, a vehicle is provided, including a cargo assembly, which is any of the cargo assemblies described above.

[0153] The embodiments of this application achieve the following technical effects: This invention discloses a carrying component that enables the opening, closing, and height adjustment of the table assembly. The table assembly disclosed in this invention is integrated into the cockpit central control system. The table assembly is unfolded and folded for storage via a support rod assembly, meeting the usage needs of the table in different states; a lifting mechanism is used to raise and lower the table assembly, meeting usage needs at different heights. This solves the current industry pain points regarding table storage, large-size tables, and the inability to adjust table height, and has broad application prospects.

[0154] In this application, "multiple" refers to two or more.

[0155] In this application, unless otherwise expressly defined, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0156] The terms “first,” “second,” “third,” “fourth,” etc., in this application (if present) are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0157] In this application, the term "and / or" merely describes the relationship between related objects, indicating that three relationships can exist. For example, "suspension structure and / or B" can represent: the existence of the suspension structure alone, the existence of both the suspension structure and B, or the existence of B alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.
