It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0072] Combination Figure 3 , Figures 21 to 31 As shown, according to a specific embodiment of this application, a lifting mechanism is provided.

[0073] Specifically, the lifting mechanism includes a flexible connector 430, an adjusting component 420, and a lifting drive 410. The first end of the flexible connector 430 is connected to the mounting base, and the second end of the flexible connector 430 is connected to the target object 30. The adjusting component 420 includes at least one movable winding member 421. Along a preset lifting direction, the movable winding member 421 is movable relative to the mounting base to adjust the distance between the movable winding member 421 and the bottom of the mounting base. The output end of the lifting drive 410 is connected to the movable winding member 421, and the lifting drive 410 is used to drive the movable winding member 421 to move along the preset lifting direction. The flexible connector 430 is wound around the movable winding member 421. The lifting drive 410 drives the movable winding member 421 to move relative to the mounting base, which can drive the second end of the flexible connector 430 to move along the preset lifting direction, thereby adjusting the position of the target object 30 in the preset lifting direction.

[0074] The embodiments of this application achieve the following technical effects: By driving the movable winding member 421 to move relative to the installation base through the lifting drive member 410, the relative distance between the movable winding member 421 and the installation base can be adjusted, thereby adjusting the length of the flexible connector 430 wound on the adjustment component 420, and thus adjusting the height of the second end of the flexible connector 430 in the preset lifting direction, thereby achieving the purpose of adjusting the position of the target object 30 in the preset lifting direction. In this embodiment, by winding the flexible connector 430 on the movable winding member 421, the shorter movement stroke of the movable winding member 421 can be converted into a larger lifting stroke of the target object 30. The lifting mechanism can achieve a larger lifting amplitude of the target object 30 in a limited space, avoiding the limitation of lifting function due to insufficient space. Even in a compact environment, the target object can achieve the ideal lifting height. At the same time, there is no need to reserve additional operating space for the drive element. Compared with the traditional lifting drive mechanism, the lifting mechanism of this embodiment reduces the space occupation requirement of the mechanism, solves the problem of space occupation of the lifting mechanism in the prior art, and saves installation space.

[0075] Meanwhile, the lifting drive 410 can provide the necessary driving force to make the movable winding member 421 move in the preset lifting direction. The lifting drive 410 can adjust the direction, magnitude and duration of the driving force as needed so that the movable winding member 421 moves a specified distance in a specified direction and at a specified speed, thereby making the position of the target object 30 more precise.

[0076] Compared to traditional coil spring drives, the solution using adjusting component 420 and flexible connector 430 reduces direct contact and friction, significantly lowering noise during pop-up and retraction. It also reduces wear and tear, extends the device's lifespan, and improves overall durability and user experience. Because the lifting drive component 410 can push the target object 30 to a greater lifting height within a shorter extension range, it optimizes space utilization, providing greater flexibility and space efficiency, making it particularly suitable for narrow or specific spaces.

[0077] It should be noted that the lifting drive component 410 can be a drive component based on various principles. For example, the lifting drive component 410 can be a telescopic drive component based on the principle of telescopic movement, such as a spring. Alternatively, the lifting drive component 410 can be other drive components with linear displacement function, such as an electric push rod that achieves linear motion by driving a lead screw or gear rack through a motor. Or, the lifting drive component 410 can also be a hydraulic cylinder, a magnetic drive structure, or other drive structures.

[0078] Furthermore, the adjustment assembly 420 also includes at least one fixed winding member 422. Along a preset lifting direction, a movable winding member 421 is movably disposed relative to the fixed winding member 422 to adjust the distance between the movable winding member 421 and the fixed winding member 422. A flexible connector 430 is wound around the fixed winding member 422 and the movable winding member 421. The lifting drive member 410 drives the movable winding member 421 to move relative to the fixed winding member 422, which can cause the second end of the flexible connector 430 to move along the preset lifting direction, thereby adjusting the position of the target object 30 in the preset lifting direction. Figure 30 As shown, the flexible connector 430 can be a steel wire rope. Depending on the actual needs, the flexible connector 430 can also be a nylon braided belt, chain, rubber belt, or other components.

[0079] The embodiments of this application achieve the following technical effects: by setting a fixed winding member 422, the direction of the flexible connector 430 can be changed so that the flexible connector 430 is wound around the fixed winding member 422 and the movable winding member 421. This can further convert the shorter movement stroke of the movable winding member 421 into a larger lifting stroke of the target object 30 more efficiently. The lifting mechanism can achieve a larger lifting range of the target object 30 in a limited space, avoiding the limitation of lifting function due to insufficient space.

[0080] In this embodiment, by adjusting the relative distance between the movable winding member 421 and the fixed winding member 422, the length of the flexible connector 430 wound on the adjustment component 420 can be adjusted, thereby adjusting the height of the second end of the flexible connector 430 in the preset lifting direction, thus achieving the purpose of adjusting the position of the target object 30 in the preset lifting direction. By winding the flexible connector 430 on the fixed winding member 422, the length of the flexible connector 430 on the winding member can be changed by increasing the number and setting position of the fixed winding member 422, further enhancing the amplification effect of the movement stroke of the movable winding member 421, reducing the space occupation requirement of the lifting mechanism, and saving installation space.

[0081] In embodiments of this application, the adjustment component 420 may include one fixed winding member 422 and two movable winding members 421. Optionally, it may also include two fixed winding members 422 and three movable winding members 421, with the flexible connector 430 sequentially passing around each of the fixed winding members 422 and the movable winding members 421. Each movable winding member 421 may move independently or synchronously.

[0082] In another exemplary embodiment of this application, the adjustment component 420 may also include only the movable winding member 421. The movable winding member 421 may be one, two, three, etc., depending on actual needs.

[0083] Furthermore, the adjustment assembly 420 also includes an adjustment bracket 423, on which a sliding rail 4230 is provided. The movable winding member 421 is movably connected to the adjustment bracket 423 through the sliding rail 4230, and the fixed winding member 422 is disposed on the adjustment bracket 423.

[0084] The above-mentioned optional embodiments of this application achieve the following technical effects: by adjusting the bracket 423 and the sliding rail 4230 to provide guidance for the movable winding member 421, it can be ensured that the movable winding member 421 moves along a predetermined path, thereby improving the stability and reliability of the movement, improving the working efficiency and durability of the adjusting component 420, reducing friction and wear during the movement, and extending the service life of the lifting mechanism.

[0085] Furthermore, there are multiple movable winding members 421, and the adjustment assembly 420 also includes a sliding guide post 4212. The multiple movable winding members 421 are all disposed on the sliding guide post 4212. The sliding guide post 4212 is movable along a preset lifting direction to adjust the distance between the multiple movable winding members 421 and the fixed winding member 422.

[0086] The above-mentioned optional embodiments of this application achieve the following technical effects: By setting multiple movable winding members 421, more precise and subtle position control of the target object 30 can be achieved by finely adjusting the position of each movable winding member 421. Furthermore, using multiple movable winding members 421 can ensure that the force distribution of the flexible connector 430 is more uniform during movement, reducing local wear. The movable setting of the sliding guide column 4212 along the preset lifting direction provides a unified movement trajectory for multiple movable winding members 421, ensuring that the movement direction of all movable winding members 421 is consistent. It can also precisely adjust the relative distance between the movable winding member 421 and the fixed winding member through its own movement, thereby controlling the lifting amplitude of the target object 30. The setting of the sliding guide column makes the movement of the entire adjustment component more coordinated and the force transmission more stable, thus ensuring the smooth operation and high efficiency of the lifting mechanism.

[0087] Furthermore, the fixed winding member 422 is a fixed pulley 4220, and / or the movable winding member 421 is a movable pulley 4210.

[0088] The above optional embodiments of this application achieve the following technical effects: The fixed pulley 4220 is mainly used to change the direction of the force, but not the magnitude of the force. In the lifting mechanism, the fixed pulley 4220, as a fixed winding member 422, can provide a stable winding member for the flexible connector, ensuring the smooth transmission of force; the movable pulley 4210 not only changes the direction of the force, but can also change the magnitude of the force through its own movement, realizing the amplification or reduction of the force. In the lifting mechanism, the movable pulley 4210, as a movable winding member 421, can amplify the driving effect through its movement, that is, to achieve a larger lifting amplitude of the target object 30 with a smaller driving distance, while reducing the force required and improving efficiency.

[0089] In one exemplary embodiment of this application, such as Figures 21 to 28 As shown, the adjusting assembly 420 includes two movable pulleys 4210 and one fixed pulley 4220. A first connecting hole 4213 and a second connecting hole 4214 are provided on the sliding guide column 4212. The first connecting hole 4213 is used to connect the movable pulleys 4210, and the second connecting hole 4214 is used to connect the lifting drive component 410. A slider 4211 is provided on the movable pulleys 4210. The bottom end of the adjusting bracket 423 is connected to the fixed pulley 4220. Multiple sliding rails 4230 are provided on the adjusting bracket 423. The movable pulleys 4210 are slidably positioned along the sliding rails 4230 via the sliders 4211. The lifting drive component 410 can drive the sliding guide column 4212 to move synchronously, thereby causing the movable pulleys 4210 to slide along the sliding rails 4230.

[0090] Furthermore, there are at least two movable winding members 421, and a fixed winding member 422 is provided between two adjacent movable winding members 421.

[0091] The above-mentioned optional embodiments of this application achieve the following technical effects: by increasing the number of movable winding members 421, the force can be distributed more evenly on the flexible connector 430, reducing the risk of excessive force on a single point, thereby improving the stability and lifespan of the entire system; by arranging movable winding members 421 and fixed winding members 422 at intervals, the fixed winding member 422 can serve as a stable point for force transmission, effectively balancing the forces between adjacent movable winding members 421, and reducing swaying or instability caused by uneven force distribution.

[0092] In another exemplary embodiment of this application, the fixed winding member 422 may also be a fixedly arranged grooved wheel or roller, and the movable winding member 421 may also be a movable grooved wheel or roller.

[0093] Furthermore, the lifting drive component 410 includes any one of a gas spring 411, an electric spring, or an electric push rod.

[0094] The above-mentioned optional embodiments of this application achieve the following technical effects: by utilizing the telescopic characteristics of the gas spring 411, electric spring, and electric push rod, vertical power can be provided to the movable winding member 421 to realize the lifting and lowering of the target object 30, thereby improving the power performance and ease of operation of the lifting mechanism. The use of the gas spring 411 or electric spring makes operation more labor-saving. The gas spring 411 runs smoothly with low noise, reducing the noise generated by the movement of the device. The intelligent control of the electric spring and electric push rod enables remote operation and automated management.

[0095] In one exemplary embodiment of this application, such as Figures 1 to 3 , Figure 21 , Figure 22 , Figure 31 As shown, the mounting base is housing 10, and the height direction of housing 10 is the preset lifting direction. The lifting drive component 410 includes a gas spring 411, and the extension and retraction direction of the gas spring 411 is the height direction of housing 10. The gas spring 411 is located in the receiving cavity 110 of housing 10. The gas spring 411 has a telescopic end 4110 and a cylinder end 4111. The telescopic end 4110 is connected to the adjustment component 420 to drive the adjustment component 420 to move along the height direction of housing 10.

[0096] In another exemplary embodiment of this application, the lifting drive 410 may include an electric push rod, the output end of which is directly connected to the adjusting assembly 420. The electric push rod can be electrically connected to an external control system to extend or retract according to an external control signal, thereby driving the adjusting assembly 420 to move. Alternatively, the lifting drive 410 may also include an electric spring, the length of which can be adjusted by changing the magnitude or direction of the current, thereby achieving the extension / retraction function. Depending on actual needs, the lifting drive 410 may also be a lead screw or other drive mechanism capable of linear displacement.

[0097] Furthermore, the fixed winding member 422 is disposed on the lifting drive member 410, or the fixed winding member 422 is disposed on the mounting base.

[0098] The above-mentioned optional embodiments of this application achieve the following technical effects: directly integrating the fixed winding component 422 onto the lifting drive component 410 can simplify the overall mechanism design, reduce additional support structures and connecting components, thereby reducing manufacturing costs and assembly complexity; setting the fixed winding component 422 on the mounting base can provide more reliable force transmission support, enhance the mechanical stability and reliability of the entire lifting mechanism, and reduce vibration and shaking during operation.

[0099] Combination Figures 4 to 19 , Figure 32 As shown, according to another specific embodiment of this application, a locking mechanism is provided.

[0100] The locking mechanism includes a locking component 50 and a support component 20. The locking component 50 includes a first mating component 510 and a second mating component mounted on the mounting base. The first mating component 510 and the second mating component are mutually mated, and the locking component 50 has a locked mating state and a released mating state. The support component 20 includes a first support component 210 and a second support component 220. The first support component 210 is provided with the first mating component 510, and the second support component 220 is connected to the target object 30. The second support component 220 is rotatably connected to the first support component 210 so that the second support component 220 can rotate to an initial position and a working position. During the process of the second support component 220 rotating from the initial position to the working position, the second support component 220 can drive the output end of the transmission component 230 to rotate in a first direction to drive the first mating component 510 to switch to the locked mating state. During the process of the second support component 220 rotating from the working position to the initial position, the second support component 220 can drive the output end of the transmission component 230 to rotate in a second direction to drive the first mating component 510 to switch to the released mating state.

[0101] The embodiments of this application achieve the following technical effects: by changing the engagement state of the first engagement component 510 and the second engagement component, the target object 30 can be locked and unlocked, effectively improving the stability of the target object 30 during use, reducing shaking, and enhancing the user experience; at the same time, by triggering the state change of the locking component 50 through the rotation of the second support component 220, the target object 30 can be automatically locked and unlocked, simplifying the operation process and improving the automation and security of the locking mechanism.

[0102] In one exemplary embodiment of this application, the second support component 220 can rotate 90° clockwise from the initial position to the working position, and the second support component 220 can rotate 90° counterclockwise from the working position to the initial position. In specific applications, the rotation direction and rotation angle for switching between the initial position and the working position can be adjusted according to actual needs.

[0103] The locking mechanism in this embodiment can be applied to the storage and use of devices such as small tables in car armrest boxes and folding tables on airplane seats. It is particularly suitable for occasions where the target object 30 needs to be frequently unfolded and retracted, such as during rest and meal times during long-distance travel. Users can easily unfold and retract the target object 30 with simple operations (such as rotating the target object 30), without the need for additional manual locking or unlocking. It is convenient to operate and highly secure.

[0104] In one exemplary embodiment of this application, such as Figure 1 As shown, the target object 30 is currently in the storage position, as... Figure 2As shown, the target object is currently in use, and, as... Figures 4 to 6 As shown, the second support component 220 is in the initial position, and the locking component 50 is in the released engagement state. When the second support component 220 is folded to... Figure 7 When in the indicated working position, the locking component 50 switches to the locking engagement state.

[0105] Furthermore, the first support component 210 includes a support 211, the support 211 having a movable cavity 212, and a through hole 213 opened on the side wall of the movable cavity 212. A portion of the first mating component 510 is located inside the movable cavity 212, and another portion of the first mating component 510 extends out of the support 211 through the through hole 213 and engages with the second mating component. The first mating component 510 is movable in a first preset direction so that the first mating component 510 has a locking position and a releasing position. When the first mating component 510 is in the locking position, the locking component 50 is in a locked engagement state. When the first mating component 510 is in the releasing position, the locking component 50 is in a released engagement state.

[0106] The above optional embodiments of this application achieve the following technical effects: the movable cavity 212 of the support 211 can provide a space for the first mating component 510 to move in the movable cavity 212 along a first preset direction, thereby cooperating with the second mating component to lock and unlock, improving the overall compactness and smoothness of operation of the locking mechanism. At the same time, the first mating component 510 is disposed inside the first support component 210, reducing the space occupied by the locking mechanism.

[0107] In one exemplary embodiment of this application, such as Figure 6 , Figures 9 to 11 , Figure 14 As shown, the support 211 includes a support box 2110 and a support cover 2111. The support box 2110 has a movable cavity 212. The support cover 2111 is used to block the opening of the support box 2110. The support cover 2111 is provided with a connecting part for rotatably connecting with the second support assembly 220.

[0108] Furthermore, the support 211 and the second support assembly 220 are rotatably connected via a rotating shaft 221. When the second support assembly 220 rotates, the rotating shaft 221 rotates synchronously. The transmission assembly 230 is connected to the rotating shaft 221. The support assembly 20 also includes a diameter-changing assembly 240, which is located in the movable cavity 212 and is connected to the transmission assembly 230. The diameter-changing assembly 240 has a contact position that contacts the first mating assembly 510. The rotation of the rotating shaft 221 can drive the diameter-changing assembly 240 to rotate via the transmission assembly 230, adjusting the distance between the contact position and the rotation center of the diameter-changing assembly 240, thereby driving the first mating assembly 510 to move in a first preset direction.

[0109] The above-mentioned optional embodiments of this application achieve the following technical effects: the rotation of the shaft 221 can be transmitted to the diameter-changing component 240 through the transmission component 230. The rotation of the diameter-changing component 240 changes the distance between its rotation center and the contact position of the first mating component 510, that is, changes the radial dimension of the contact position of the first mating component 510, so that the first mating component 510 moves along the first preset direction, adjusts the movement trajectory of the first mating component 510, achieves precise control, improves the response speed and accuracy of the locking mechanism, and makes the locking and unlocking of the target object 30 faster and smoother.

[0110] It should be noted that in this embodiment, the rotating shaft 221 and the second support component 220 move synchronously. That is, when the second support component 220 rotates relative to the first support component 210, the rotating shaft 221 rotates synchronously with the second support component 220, thereby transmitting the rotation of the second support component 220 to the transmission component 230 and the variable diameter component 240. The first preset direction coincides with the radial direction of the variable diameter component 240. When the variable diameter component 240 rotates, the radial dimension of the contact position between the variable diameter component 240 and the first mating component 510 changes, thereby pushing the first mating component 510 to move along the first preset direction. Optionally, when the mounting base is the housing 10, the first preset direction is the width direction or the length direction of the housing 10.

[0111] Furthermore, the transmission assembly 230 includes a first bevel gear 231, a second bevel gear 232, and a transmission shaft 233. The first bevel gear 231 is mounted on the rotating shaft 221 and rotates synchronously with the rotating shaft 221. The first end of the transmission shaft 233 is connected to the variable diameter assembly 240, and the first end of the transmission shaft 233 is the output end of the transmission assembly 230. The second end of the transmission shaft 233 extends to the outside of the support 211. The second bevel gear 232 is mounted on the second end of the transmission shaft 233 and meshes with the first bevel gear 231. The second bevel gear 232 and the variable diameter assembly 240 both rotate synchronously with the transmission shaft 233.

[0112] The above-mentioned optional embodiments of this application achieve the following technical effects: by utilizing the characteristics of bevel gear transmission, the rotation of the rotating shaft 221 is converted into the rotation of the transmission shaft 233, and the rotation of the transmission shaft 233 further drives the variable diameter component 240, realizing the transmission of force and the change of direction. Gear transmission can improve transmission efficiency and reduce energy loss in the transmission process. At the same time, the design of bevel gears allows the transmission component 230 to adapt to different spatial layouts, increasing the flexibility of the design.

[0113] In an alternative embodiment of this application, the transmission assembly 230 includes a connecting rod assembly, a slider, and a slider guide tube. The two ends of the connecting rod assembly are respectively connected to the rotating shaft 221 and the slider. The slider has two support arms. The slider guide tube is fixedly connected to the variable diameter assembly. A rotating guide groove is provided inside the slider guide tube. The slider is located in the rotating guide groove. When the connecting rod assembly drives the slider to move up and down, it drives the rotating guide groove to rotate, thereby driving the variable diameter assembly to rotate through the slider guide tube.

[0114] Furthermore, the variable diameter assembly 240 includes a cam structure 241, which has a contact position. The transmission assembly 230 rotates to drive the cam structure 241 to rotate, adjusting the cam radius at the contact position, thereby driving the first mating assembly 510 to move along a first preset direction.

[0115] The above-mentioned optional embodiments of this application achieve the following technical effects: Based on the variable diameter characteristic of the cam structure 241, by changing the cam radius at the contact position, precise control of the first mating component 510 can be achieved, making the locking and unlocking of the target object 30 more reliable, improving the stability and reliability of the locking mechanism, reducing the risk of locking failure due to mechanical wear or improper operation, and the precise control of the cam structure 241 can ensure the safety and stability of the target object 30 during use, and can be adapted to application scenarios that require high precision and stability.

[0116] In an alternative embodiment of this application, the variable diameter assembly 240 includes a non-circular gear with a toothed outer surface. The first mating assembly 510 has teeth for meshing with the non-circular gear, so that when the non-circular gear rotates, the toothed structure on its outer surface meshes with the teeth on the first mating assembly 510, driving the first mating assembly 510 to move. The toothed meshing design makes the movement of the first mating assembly 510 more reliable.

[0117] In another alternative embodiment of this application, the variable diameter assembly 240 includes a Geneva assembly, which includes a driving dial and a driven Geneva wheel. The driving dial has a pin, and the driven Geneva wheel has a radial groove and an inwardly recessed locking arc. The driving dial also has an outwardly recessed locking arc. The driving dial rotates with the transmission assembly 230. As the driving dial rotates, the outer circumferential surface of the driven Geneva wheel contacts the first mating assembly 510 in sequence. During the process of moving from the lowest point of the inwardly recessed locking arc (i.e., the position closest to the rotation center of the driven Geneva wheel) to the highest point (i.e., the position farthest from the rotation center of the driven Geneva wheel), the first mating assembly 510 moves radially along the driven Geneva wheel. That is, the linear motion drive of the first mating assembly 510 is achieved through the movement of the Geneva assembly.

[0118] Furthermore, the first mating assembly 510 includes a sliding member 511 and a locking member 512. The sliding member 511 is disposed in the movable cavity 212 and is in contact with the variable diameter assembly 240. The first end of the locking member 512 is connected to the sliding member 511, and the second end of the locking member 512 extends outside the support 211. The sliding member 511 is movable along a first preset direction to adjust the length of the locking member 512 extending outside the support 211. When the second end of the locking member 512 extends into the second mating assembly, the locking assembly 50 is in a locked mating state. When the second end of the locking member 512 moves away from the second mating assembly, the locking assembly 50 is in a released mating state.

[0119] The above optional embodiments of this application achieve the following technical effects: the movement of the sliding member 511 can drive the locking member 512 to extend and retract. When the second end of the locking member 512 is inserted into the second mating component, a stable locking state is formed; otherwise, it is a released state. This simplifies the structure of the locking mechanism, improves the ease of operation and safety, and can effectively enhance the user experience when applied to the target object 30 that needs to be frequently locked and unlocked.

[0120] In one exemplary embodiment of this application, the second mating component includes a locking hole formed in the mounting base. When the locking member 512 is inserted into the locking hole, the locking component 50 is in a locking engagement state; when the locking member 512 is not inserted into the locking hole, the locking component is in a released engagement state. Depending on actual needs, the second mating component can also be configured as a stop structure, a snap-fit ​​structure, etc., so that the locking component 50 locks the target object 30, preventing the target object 30 from moving up and down, thus preventing the target object 30 from being used normally.

[0121] Furthermore, the first mating assembly 510 also includes a reset elastic member 513, the first end of which is connected to the sliding member 511, and the second end of which is connected to the support 211; wherein, when the locking assembly 50 is in the released mating state, the reset elastic member 513 is in the natural state, and when the locking assembly 50 is in the locked mating state, the reset elastic member 513 is in the deformed state.

[0122] The above-mentioned optional embodiments of this application achieve the following technical effects: the elastic force of the reset elastic member 513 can provide the sliding member 511 with the ability to automatically reset, ensuring that the sliding member 511 can quickly return to the initial position when released, ready for the next locking. By setting the reset elastic member 513, the automation level and reliability of the locking mechanism are improved, the need for manual operation is reduced, and the locking and unlocking of the target object 30 is smoother.

[0123] In one exemplary embodiment of this application, such as Figure 15 , Figure 16 and Figure 19As shown, the reset elastic element 513 is a reset spring, and the first mating assembly 510 also includes a fixed post 514 disposed on the sliding element 511, with the reset spring sleeved on the fixed post 514.

[0124] Furthermore, a first slide rail 214 is provided inside the movable cavity 212. The first slide rail 214 extends along a first preset direction, and the sliding member 511 is slidably connected to the first slide rail 214.

[0125] The above optional embodiments of this application achieve the following technical effects: the first slide rail 214 can provide guidance for the slider 511, ensuring that the slider 511 moves accurately along the first preset direction, thereby realizing stable control of the first mating component 510, improving the motion accuracy and motion stability of the locking mechanism, reducing deviation and shaking during the motion process, and making the locking and unlocking of the target object 30 more accurate and stable.

[0126] In one exemplary embodiment of this application, such as Figure 9 and Figure 10 As shown, the mounting base is the housing 10, the first preset direction is the width direction of the housing 10, and there are two first slide rails 214. The two first slide rails 214 are arranged at a distance along the length direction of the housing 10 so that both ends of the slider 511 can extend into one of the first slide rails 214, thereby making the movement of the slider 511 more stable.

[0127] Furthermore, the support 211 is provided with two first mating components 510, and the mounting base is provided with two second mating components. The two second mating components are provided in a one-to-one correspondence with the two first mating components 510. The two first mating components 510 are provided relative to each other along a first preset direction, and the variable diameter component 240 is located between the two first mating components 510.

[0128] The above-mentioned optional embodiments of this application achieve the following technical effects: by setting two first mating components 510 and two second mating components, a dual locking mechanism is formed, which improves the stability and security of locking the target object 30. Even if one of the first mating components 510 fails, the other first mating component 510 can still maintain the locked state of the target object 30, avoiding the risk of accidental unlocking. At the same time, by setting the variable diameter component 240 between the two first mating components 510, the synchronous control of the two first mating components 510 can be achieved through one variable diameter component 240, which simplifies the structure of the locking mechanism.

[0129] In one exemplary embodiment of this application, the mounting base is a housing 10, and two first mating components 510 are spaced apart along the width direction of the housing 10. Both first mating components 510 are movably arranged along the width direction of the housing 10 to switch between a locked state and a released state. Specifically, a variable diameter component 240 is located between the two first mating components 510, and the rotation of the variable diameter component 240 synchronously drives the two first mating components 510 to switch states.

[0130] Combination Figures 1 to 32 As shown, according to another aspect of the embodiments of this application, a storage device is provided, which includes a lifting mechanism and a locking mechanism, wherein the lifting mechanism is the lifting mechanism described above, and the locking mechanism is the locking mechanism described above.

[0132] Furthermore, the storage device includes a housing 10, which has a receiving cavity 110 with one end open.

[0139] The embodiments of this application achieve the following technical effects: by integrating the storage device into the seat assembly, the automatic pop-out and storage of seat accessories can be achieved by utilizing the lifting and locking functions of the storage device, thereby improving the functionality and comfort of the seat assembly. This allows seat accessories such as small tables and storage boxes to be stored when not in use, saving space, and to be quickly raised when needed for convenient operation.

[0140] The seat assembly in this embodiment can be a seat in a means of transportation such as a vehicle seat, an airplane seat, or a ship seat. The integrated design of the seat assembly can meet passengers' high requirements for comfort and functionality, and improve the riding experience.

[0141] Furthermore, the seat assembly also includes a seat body and a seat table, wherein the storage device is connected to the seat body, and the target object 30 is the seat table.

[0142] The above-mentioned optional embodiments of this application achieve the following technical effects: By combining the seat table with the storage device, and utilizing the lifting and locking functions of the storage device, the automatic lifting and storage of the seat table can be realized, which improves the multifunctionality and space utilization of the seat, allowing the seat table to be stored when not in use, saving space, and to be quickly raised when needed, making it convenient to operate.

[0145] Combination Figures 1 to 32 As shown, this application also provides a preferred embodiment of a storage device, which is mainly used to solve the problems of high noise, high energy loss due to friction, and elastic decay when the table is popped out by the coil spring in the prior art.

[0146] Specifically, the storage device includes a housing 10 (such as...) Figure 20 As shown), the structure comprises a support assembly 20, a target object 30, a lifting mechanism 40, and a locking assembly 50. A housing track 120 is provided inside the housing 10. The target object 30 is a tabletop. A guide slider 250 is provided on the outer wall of the support assembly 20. The support assembly 20 moves along the housing track 120 via the guide slider 250, thereby guiding the tabletop to rise and fall. The lifting mechanism 40 includes a gas spring 411 (i.e., the aforementioned lifting drive component 410), two movable pulleys 4210, a sliding guide column 4212, a fixed pulley 4220, an adjusting bracket 423, and a pull rope (e.g., a gas spring 411, a target object 30, a lifting mechanism 40, and a locking assembly 50). Figure 30 As shown, this refers to the aforementioned flexible connector 430. The gas spring 411 is connected to the sliding guide post 4212 to drive the two movable pulleys 4210 to rise and fall; the pull rope passes over the fixed pulley 4220 and the movable pulley 4210, and one end is connected to the housing 10, while the other end is connected to the support assembly 20; the gas spring 411 serves as the power source, and the extension of the gas spring 411 is amplified four times by the combination of "double movable pulleys + fixed pulleys".

[0147] Among them, such as Figure 31 As shown, the gas spring 411 includes a telescopic end 4110 and a cylinder end 4111. The cylinder end 4111 is the fixed end of the gas spring 411. Both the telescopic end 4110 and the cylinder end 4111 have a mounting point. Figure 25 and Figure 26 As shown, a slider 4211 is hinged to the movable pulley 4210. (As indicated...) Figure 24 As shown, the sliding guide post 4212 has two first connecting holes 4213 and one second connecting hole 4214. The movable pulley 4210 is hinged to the sliding guide post 4212 through the first connecting hole 4213, and the telescopic end 4110 is connected to the sliding guide post 4212 through the second connecting hole 4214. Figure 27 and Figure 28As shown, the adjusting bracket 423 has a hinge hole for connecting with the fixed pulley 4220, and a sliding rail 4230 for cooperating with the slider 4211. The adjusting bracket 423 is mounted on the housing 10, the two movable pulleys 4210 are slidably connected to the adjusting bracket 423, and the fixed pulley 4220 is mounted on the bottom of the adjusting bracket 423.

[0148] like Figure 12 As shown, the second support component 220 is connected to the tabletop. Figure 13 As shown, the second support assembly 220 is hinged to the first support assembly 210. Figure 32 , Figure 14 As shown, the support cover 2111 is provided with a hinge hole for hinged connection with the second support assembly 220. The support cover 2111 also has a mating hole. A guide slider 250 is screwed to the outer wall of the support 211. The first support assembly 210 moves along the housing track 120 via the guide slider 250, thereby achieving tabletop lifting and guiding. The support assembly 20 includes a rotating shaft 221 and a first bevel gear 231 (e.g., ...). Figure 17 (as shown), drive shaft 233, second bevel gear 232 and cam structure 241 (as shown) Figure 18 As shown, the drive shaft 233 is mounted on the support 211 and passes through the mating hole on the support cover 2111.

[0149] Locking assembly 50 includes a front locking pin slider disposed within the support box 2110 (one of the two first mating assemblies 510, such as...). Figure 15 (as shown) and the rear locking pin slider (the other of the two first mating components 510, as ... Figure 16 As shown, the tabletop flips down, causing the rotating shaft 221 to rotate. The first bevel gear 231 and the second bevel gear 232 mesh and rotate, driving the cam structure 241 to rotate. This causes the cam structure 241 to drive the front locking pin slider and the rear locking pin slider to slide into the locking hole on the housing 10 to achieve locking.

[0150] like Figure 9 As shown, the support box 2110 has a movable cavity 212. The side wall of the movable cavity 212 is provided with a through hole 213 and a reset hole 215. The support box 2110 is also provided with a first slide rail 214. The through hole 213 is used for the locking pin to pass through. The first slide rail 214 is used to cooperate with the locking pin slider (including the front locking pin slider and the rear locking pin slider) to slide. The reset hole 215 is used to install the locking pin reset spring.

[0151] The front and rear locking pin sliders have the same structure, both including a sliding member 511, a locking member 512, a reset elastic member 513, and a fixing post 514. In this embodiment, "front" and "rear" are used to distinguish the two first mating components 510. The front and rear locking pin sliders extend in different directions; in this embodiment, "front" and "rear" refer to the width direction of the housing 10. Figure 2 As shown, two guide sliders 250 are respectively disposed on both sides of the support box 2110 along the length direction of the housing 10, and two first mating components 510 extend and retract along the width direction of the housing 10. Along the length direction of the housing 10, a gas spring 411 and an adjusting component 420 are disposed on one side of the support mechanism. In specific configurations, the extension and retraction direction of the first mating components 510 and the placement position of the guide sliders 250 can also be adjusted.

[0152] The working process of the pop-up storage device in this embodiment is as follows:

[0153] Tabletop pop-up process: When the tabletop is in its retracted state, the gas spring 411 pushes the sliding guide post 4212 and the movable pulley 4210 to move upward along the track, as... Figure 2 As shown, during this process, the fixed end of the wire rope and the support 211 will drive the table to move upward along the slide rail, and the upward speed of the table is 4 times the extension speed of the gas spring 411, so that the gas spring 411 extends to a small height and pops the table to a large height. At this time, the gas spring 411 does not have the problem of being exposed.

[0154] Tabletop locking and unlocking process: as follows Figure 7 As shown, when the tabletop is folded down and locked, the drive shaft 221 and the first bevel gear 231 rotate, and the second bevel gear 232 rotates, causing the transmission shaft 233 and the cam structure 241 to rotate 90°. During this process, the cam structure 241 drives the front locking pin slider and the rear locking pin slider to slide back and forth respectively, so that the front locking pin slider and the rear locking pin slider are respectively inserted into the locking holes on the housing 10, realizing linkage locking; as Figure 8 As shown, when the table flips up and resets, it rotates in the opposite direction to the flipping process, turning the cam structure 241 back to its original state. At this time, under the driving force of the reset spring, the front locking pin slider and the rear locking pin slider will reset to their original positions, realizing linkage unlocking.

[0155] The following beneficial effects can be achieved by using the pop-up storage device in this embodiment for tabletop storage:

[0156] 1) A gas spring 411 is used instead of a coil spring to drive the table to pop out, avoiding the adverse effects of abnormal noise, high friction loss, and easy elastic decay during the movement of the coil spring; 2) The stroke amplification principle of the double-acting pulley is adopted, so that the table can be popped out to a greater height by extending the spring to a smaller height. There is no problem of the gas spring 411 being exposed. That is, by amplifying the extension of the gas spring 411, the pop-out height of the table can be guaranteed while the gas spring 411 does not protrude; 3) The cam rotation is driven by bevel gear transmission to realize the double pin locking of the table flipping linkage. The function is reliable. During the process of the table rising and flipping, the two pins automatically lock with the housing 10, maintaining the table's raised position while reducing the amount of shaking of the table during use.
