Description

Technical Field

[0001] This invention belongs to the field of new energy applications and portable furniture, specifically relating to a modular folding solar-powered table. Background Technology

[0002] With increasing environmental awareness and the development of new energy technologies, solar tables are gradually becoming a type of furniture product that combines practicality and innovation. However, traditional solar tables typically feature a fixed tabletop design, which often results in problems such as bulkiness, inconvenience in carrying, and limited functionality. This makes it difficult to meet users' needs for portability and multifunctionality, as well as their usage needs in different scenarios, such as outdoor activities, emergency power supply, or home backup power.

[0003] Furthermore, while some existing solar tables are foldable, they may suffer from insufficient stability or cumbersome assembly in practice, and still occupy a significant amount of space when folded, failing to fully combine portability with efficient storage. At the same time, existing solar tables also have limitations in energy management, such as lacking efficient energy conversion and storage mechanisms, thus failing to fully meet users' diverse electricity needs. Summary of the Invention

[0004] (1) Technical problems to be solved

[0005] This invention discloses a modular folding solar-powered table, which aims to solve the problems of complex structure, large space occupation, difficulty in storage and carrying, and limited function of existing solar tables.

[0006] (2) Technical solution

[0007] The present invention discloses a modular foldable solar-powered table, including at least two foldable and connectable table panels, a support structure, a locking structure and a charging component disposed at the bottom of the table panels, wherein the table panels are disposed on the support structure and are rotatably connected to the support structure to switch the horizontal or vertical placement state of the table panels.

[0008] Each of the supporting structures is connected to a hinge structure at one end close to each other. Each of the tabletops can be unfolded and together form a tabletop or folded to form a parallel structure under the action of the hinge structure. The supporting structure is used to support the tabletop in the unfolded state. The locking structure is used to lock or unlock the horizontal use position of two adjacent tabletops.

[0009] The tabletop integrates a photovoltaic area, and the charging component is electrically connected to the photovoltaic area of ​​each tabletop. The charging component also has a built-in central power management module for managing solar power generation and providing power output.

[0010] Furthermore, the number of tabletops is four, and the overall volume of each tabletop after being stored is equivalent to 1 / 4 of its volume in the unfolded state.

[0011] Furthermore, the support structure includes an "L"-shaped crossbeam and table legs, with the tabletop rotatably connected to the crossbeam. In the unfolded state, the tabletop and table legs are perpendicular to each other; in the folded state, the tabletop and table legs are parallel to each other.

[0012] Furthermore, the hinge structure includes a locking member and rotating members corresponding to the support structure. The rotating members are hinged to each other. When the rotating members rotate around the hinge point and form a closed loop, the locking member is used to connect two adjacent rotating members at the point of forming the closed loop, so that a fixed structure is formed between the rotating members.

[0013] Furthermore, in the folded state, the line connecting the center points Q of each of the rotating components lies on the same horizontal line.

[0014] Furthermore, the charging component includes a junction box and a control panel located inside the junction box. One end of the junction box is provided with an input interface. The input interfaces of two adjacent charging components are electrically connected to a common connecting line, which is used to connect the photovoltaic areas of each of the tables in series or parallel.

[0015] Furthermore, the support structure is provided with a wire placement block at the hinge structure, and the wire placement block is provided with a wire passage hole. The two ends of the connecting wire pass through the wire passage hole and are connected to the two adjacent junction boxes respectively.

[0016] Furthermore, the junction box is also provided with several output interfaces, which are used to connect to and charge external devices.

[0017] Furthermore, the locking mechanism includes a fixing member, a connecting member, a connecting shaft and an elastic member located within the fixing member. The fixing member has a sliding groove, the connecting shaft is located within the sliding groove and one end passes through the sliding groove and is screwed to the connecting member. The elastic member is sleeved on the connecting shaft and has an inward elastic resistance force on the connecting shaft. Under the action of the elastic member, the connecting member can move outward along the axial direction of the connecting shaft.

[0018] Furthermore, the fixing member is also provided with a positioning block, and the connecting member is provided with a positioning hole that matches the positioning block;

[0019] When locked, after pulling the connector outward, the connector is rotated toward the adjacent tabletop until the connector abuts against the tabletop. Under the action of the elastic element, the connector moves inward, thereby locking the positioning block with the positioning hole.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] By incorporating a support structure and hinge mechanism, the tabletop can be flexibly unfolded and folded, improving space utilization and enhancing portability. Furthermore, the integrated photovoltaic area within the tabletop efficiently absorbs solar energy and stores or directly outputs it through a central power management module, providing users with sustainable green energy. This not only solves the problem of limited functionality in traditional solar energy products but also organically combines furniture with new energy technologies. This makes the product both a high-efficiency solar power generation platform and a practical outdoor table, enhancing the user experience and increasing its practicality.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] like Figure 1-4 As shown, this invention discloses a modular folding solar-powered table, including at least two foldable and connectable tabletops 1, and a support structure 2, a locking structure 3, and a charging assembly 4 disposed at the bottom of the tabletops 1. The tabletops 1 and the support structures 2 correspond one-to-one and are rotatably connected to each other to switch the horizontal or vertical placement of the tabletops 1. Each support structure 2 has a hinge structure 5 connected to one end of each other. Under the action of the hinge structure 5, each tabletop 1 can rotate around the hinge point and together form a tabletop or fold into a parallel structure. The support structure 2 supports the tabletop in the unfolded state, so that the tabletops 1 and the support structure 2 together form a stable platform, i.e., a stable tabletop. The locking structure 3 is used to fix two adjacent tabletops 1 in a horizontal position when the tabletops 1 are unfolded, ensuring that the tabletop remains stable during use.

[0038] When unfolded for use, the hinge structures 5 are connected end to end to form a fixed structure. At this time, the support structure 2 will automatically unfold as the hinge structure 5 rotates. Then, the tabletop 1 can be rotated to form a horizontal position. Finally, under the action of the locking structure 3, two adjacent horizontally placed tabletops 1 can be connected and fixed to each other, thereby splicing together to form a stable table for use.

[0039] Conversely, when folding and storing, first release the locking structure 3 from fixing the two adjacent horizontally placed tabletops 1, then rotate the tabletops 1 around the support structure 2 to an upright position. Next, unlock the hinge structure 5 by locking member 51, allowing the hinge structure 5 to regain its rotational freedom. Then, under the action of the hinge structure 5, the support structure 2 can move towards the center, causing the tabletops 1 to fold and form a compact, parallel structure. This makes the overall volume of each tabletop 1 after storage only about the volume of one tabletop 1. Moreover, the folded table has a flat rectangular structure, which is more regular and easier to store in a backpack, car trunk, or hang on outdoor equipment, improving the user experience.

[0040] The tabletop 1 integrates a photovoltaic area 11, which is precisely embedded into the surface of the tabletop 1, ensuring both aesthetics and improved photoelectric conversion efficiency. The charging component 4 incorporates a central power management module, which monitors the solar power generation status in real time, optimizes the generated power, and provides multiple power output interfaces to meet the charging needs of different devices, offering users sustainable power support. By designing the tabletop 1 as a modular structure, combining the photovoltaic panel and support structure 2 into a foldable table, this product combines desktop wireless charging, multiple types of wired power output, and quick storage. This effectively solves the problem of existing technologies where solar energy devices and furniture functions are separated, limiting the table's functionality and user experience. It significantly improves the product's practicality and adaptability, making it suitable not only for home gardens but also for outdoor camping, emergency power supply, or mobile office scenarios, significantly increasing the product's utilization rate and user experience.

[0041] Specifically, the tabletop 1 is made of a light-transmitting material with structural strength, not limited to glass. For example, high-strength acrylic or polycarbonate materials can be used. These materials not only ensure the light transmittance of the tabletop 1 to support the efficient photoelectric conversion of the photovoltaic area 11, but also have good impact resistance and weather resistance, maintaining stable performance in various environments. Alternatively, it can be selected from one or more combinations of tempered glass, transparent polymer composite board, flexible thin film substrate, and transparent ceramics. In addition, the tabletop 1 supports a variety of advanced photovoltaic integration materials to adapt to different cost and performance requirements. At the same time, the surface of the tabletop 1 undergoes special treatment, featuring anti-slip, anti-scratch, and easy-to-clean characteristics, further enhancing the product's durability and user experience.

[0042] Furthermore, the number of the support structures 2 corresponds one-to-one with the number of the tabletops 1.

[0043] In this embodiment, the number of tabletops 1 is preferably four to balance the needs of portability and desktop area. When unfolded, the hinge structure 5 connects and forms a closed loop structure. The four support structures 2 automatically unfold and form table legs as the hinge structure 5 rotates. The structure of the four table legs corresponds to the four tabletops 1, ensuring that the desktop load is evenly distributed in the unfolded state, thereby forming a more stable quadrilateral frame, making the support more stable and balanced. When folded for storage, the hinge structure 5 unfolds into a horizontal chain. At the same time, the support structures 2 and the tabletops 1 automatically fold into a parallel structure as the hinge structure 5 rotates, finally stacking to form the size of a single tabletop 1. That is, the overall volume of each tabletop 1 after storage is about 1 / 4 of the volume in the unfolded state.

[0044] In practical applications, the number of tabletops 1 can be adjusted according to actual needs.

[0045] Specifically, such as Figure 5 As shown, the support structure 2 includes a crossbeam 21 and table legs 22. One end of the crossbeam 21 is screwed to one end of the table legs 22, so that the crossbeam 21 and the table legs 22 form an "L" shape. The bottom side of the tabletop 1 is rotatably connected to the crossbeam 21 through a hinge 24. This allows the tabletop 1 to be connected to the support structure 2 while simultaneously rotating and folding relative to the crossbeam 21 in the vertical direction. The tabletop 1, which is horizontally placed in the unfolded state, is rotated downwards to form a vertically placed state, which is parallel to the axis of the table legs 22 and together forms a compact folding structure. This not only saves space but also facilitates transportation and storage, making it particularly suitable for scenarios that require frequent movement or storage.

[0046] Preferably, the upper and lower end faces of the tabletop 1 are screwed with strip-shaped fixing plates 12. One side of the hinge 24 is screwed to the side of the crossbeam 21, and the other side is screwed to the fixing plate 12 on the lower end face of the tabletop 1. By setting the fixing plate 12, the stress generated by the tabletop 1 during folding and unfolding can be effectively distributed, avoiding loosening or deformation caused by long-term use and extending the service life of the tabletop 1. It can also enhance the pressure resistance and load-bearing capacity of the tabletop 1.

[0047] Furthermore, such as Figure 6-8 As shown, the hinge structure 5 includes a locking member 51 and a rotating member 52 corresponding to the support structure 2. The rotating member 52 is located at the connection between the crossbeam 21 and the table leg 22, and has a complementary first side 521 and a second side 522. The first side 521 is provided with a connecting groove 523, and the second side 522 is provided with a connecting block 524. The connecting groove 523 and the connecting block 524 are respectively provided with a first shaft hole 5231 and a second shaft hole 5241. During assembly, the connecting block 524 of the rotating member 52 is inserted into the connecting groove 523 of the adjacent rotating member 52, and then the hinge shaft is inserted into the first shaft hole 5231 and the second shaft hole 5241 in sequence to realize the rotational connection of the two adjacent rotating members 52, so that a hinge structure 5 is formed between each rotating member 52.

[0048] When each of the rotating parts 52 rotates around the hinge point and forms a closed loop, the locking part 51 is used to connect two adjacent rotating parts 52 at the closed loop, thereby forming a fixed structure between each rotating part 52. At this time, the tabletop 1 is in an unfolded state and can be used as a table. When it needs to be folded for storage, the user only needs to pull out the locking part 51, and each rotating part 52 can return to a free rotation state. Then, by rotating the tabletop 1 horizontally, folding and storage can be easily completed. In the folded state, the line connecting the center points Q of each rotating part 52 is on the same horizontal line, making the whole structure more compact and easy to carry and store.

[0049] Furthermore, the first side 521 includes a first inner side 5211 and a first outer side 5212, and the second side 522 includes a second inner side 5221 and a second outer side 5222. When the hinge structure 5 rotates to form a closed loop, the first inner side 5211 of the first side 521 of the rotating member 52 and the second inner side 5221 of the adjacent rotating member 52 are in close contact with each other. Under this structure, the rotating members 52 are seamlessly connected, which can not only effectively avoid loosening or misalignment caused by external force, but also provide users with a flatter and more reliable support plane in the unfolded state, preventing damage to the rotating members 52 due to excessive rotation. In the folded state, the hinge structure 5 will rotate to form a strip-shaped chain. At this time, the first outer side 5212 of each rotating member 52 is in close contact with the second outer side 5222 of the adjacent rotating member 52, thereby forming a more stable and neat arrangement structure between the components, which can effectively reduce the vibration and noise caused by component misalignment during transportation, and make transportation more stable.

[0050] In addition, the locking element 51 is designed with a quick-plug mechanism, which is simple to operate and stable and reliable. It can effectively prevent accidental loosening caused by external force during use, further improving the safety and reliability of the product.

[0051] Furthermore, such as Figure 9 As shown, the rotating component 52 is also provided with a slot 525 that is adapted to the table leg 22. The side of the slot 525 is provided with a clearance opening 526 that is adapted to the crossbeam 21. During installation, the clearance opening 526 is aligned with the position of the crossbeam 21 and inserted to realize the insertion of the rotating component 52 and the table leg 22. The slot 525 simultaneously wraps the connection between the table leg 22 and the crossbeam 21, which not only avoids interference with the crossbeam 21, but also enhances the compactness and stability of the overall structure, so that both the table leg 22 and the crossbeam 21 can rotate with the rotation of the rotating component 52.

[0052] Preferably, the table legs 22 are made of aluminum tubing and have undergone anodizing treatment, exhibiting excellent corrosion resistance and wear resistance, enabling long-term use in complex outdoor environments without significant damage. Simultaneously, the lightweight nature of aluminum further enhances the overall portability of the table, facilitating quick relocation and deployment in various scenarios.

[0053] Preferably, such as Figure 2 As shown, a buffer pad 221 is also fitted on the table leg 22. The length of the buffer pad 221 is adapted to the side length of the table board 1, which is used to prevent the table board 1 from colliding with the table leg 22 when folded, so as to affect the normal use of the photovoltaic area 11 or even cause damage.

[0054] In some embodiments, the tabletop 1 can be rectangular, square, or fan-shaped. In this embodiment, the tabletop 1 is preferably fan-shaped. With this fan-shaped structure, the tabletops 1 can be connected to form a circular desktop when unfolded. This not only increases the aesthetics of the desktop but also better adapts to different usage scenarios and spatial layouts. Furthermore, the circular desktop provides more even load-bearing capacity, effectively distributing pressure and preventing structural damage caused by excessive localized stress. In addition, the circular desktop design reduces the risk of bumps and knocks from the corners, further enhancing safety, especially suitable for families with children or the elderly.

[0055] Furthermore, such as Figure 10-11 As shown, the locking structure 3 is disposed on the end of the crossbeam 21 away from the rotating member 52, and includes a fixing member 31, a connecting member 32, a connecting shaft 33 and an elastic member 34 located in the fixing member 31. The fixing member 31 is screwed to the crossbeam 21. The fixing member 31 is provided with a sliding groove 311. The connecting shaft 33 is located in the sliding groove 311 and one end passes through the sliding groove 311 and is screwed to the connecting member 32, so that the connecting member 32 elastically abuts against the outside of the fixing member 31. The elastic member 34 is sleeved on the connecting shaft 33 and one end elastically abuts against the end of the connecting shaft 33, so that the connecting shaft 33 always has an inward tendency due to the restoring force of the elastic member 34, thereby driving the connecting member 32 to move inward, so that the connecting member 32 is kept in a state of tight abutment against the outside of the fixing member 31.

[0056] The fixing member 31 is provided with a positioning block 312, and the connecting member 32 is provided with a positioning hole 321 that matches the positioning block 312. When the tabletop 1 is in the unfolded state, by pulling the connecting member 32 outward, the connecting member 32 can be moved outward along the axial direction of the connecting shaft 33 under the action of the elastic member 34. Then, the connecting member 32 is rotated towards the adjacent tabletop 1 until the connecting member 32 abuts against the tabletop 1. At this time, the positioning block 312 and the positioning hole 321 are in the same position. The connecting member 32 will automatically move inward under the action of the elastic member 34, thereby locking the positioning block 312 with the positioning hole 321. This can restrict the rotation of the connecting member 32, realize the locking between the two adjacent tabletops 1, and ensure that the tabletop remains horizontal and stable in the unfolded state.

[0057] When unlocking is required, simply pull the connector 32 gently to separate the positioning block 312 from the positioning hole 321, and then rotate the connector 32 in the opposite direction to complete the unlocking action. This locking structure 3 not only simplifies operation—users only need to gently pull and rotate the connector 32 outwards to lock or unlock—but also greatly improves ease of use. Simultaneously, the restoring force of the elastic element 34 ensures a good fit between the connector 32 and the positioning block 312, preventing loosening due to external forces and thus enhancing the overall structural reliability.

[0058] Preferably, to further enhance the stability of the locking structure 3, the tabletop 1 is also provided with a buckle 13, and the connector 32 is provided with a slot (not shown in the figure) that matches the buckle 13. When the connector 32 rotates and abuts against and locks against the adjacent tabletop 1, the buckle 13 and the slot engage simultaneously, thereby further strengthening the tightness of the connection between adjacent tabletops 1.

[0059] Furthermore, the central power management module has a maximum power point tracking (MPPT) circuit and a battery management system (BMS) function, and is connected to an energy storage battery. Each photovoltaic area 11 of the tabletop 1 has a built-in high-efficiency photovoltaic cell unit, such as monocrystalline silicon, polycrystalline silicon, or thin-film solar cells, which can achieve a photoelectric conversion efficiency of ≥20%. When the photovoltaic area 11 on the tabletop 1 absorbs solar energy and converts it into electrical energy, the maximum power point tracking circuit can monitor the output status of the photovoltaic area 11 in real time and adjust the operating point through intelligent algorithms to ensure that the photovoltaic area 11 always converts electrical energy at the highest efficiency. The battery management system is responsible for precisely controlling the charging and discharging process of the energy storage battery to avoid overcharging or over-discharging, thereby extending the battery's service life.

[0060] Furthermore, the central power management module features multiple protection functions, including overvoltage protection, overcurrent protection, and temperature protection, which can automatically cut off the circuit in abnormal situations to ensure the safety of equipment and users. Through this efficient energy management method, the present invention not only improves the efficiency of solar energy utilization but also provides users with more stable and reliable power support, especially suitable for power needs during extended outdoor activities or emergencies.

[0061] Furthermore, such as Figure 12As shown, the number of charging components 4 corresponds to the number of tabletops 1, with four components. Each pair of adjacent charging components 4 is connected by a connecting line 43. The two ends of each connecting line 43 are electrically connected to two adjacent charging components 4, allowing each charging component 4 to be electrically connected to its left and right counterparts simultaneously via two connecting lines 43. In other words, the four charging components 4 are electrically connected to each other via four connecting lines 43. Furthermore, the connecting lines 43 allow users to arbitrarily combine the series / parallel structures between the photovoltaic areas 11 on each tabletop 1, enabling any photovoltaic area 11 to supply power to each charging component 4. That is, as long as one of the four photovoltaic areas 11 is still functioning normally, it can simultaneously supply power to all four charging components 4, ensuring that all four charging components 4 can function normally. This improves the overall reliability and flexibility of the power supply, further enhancing the stability and practicality of the product.

[0062] Specifically, the charging component 4 includes a junction box 41 and a control panel 42 located inside the junction box 41. One end of the junction box 41 is provided with an input interface 411, which is plugged into the connector 43. This allows the user to arbitrarily combine the connections between the charging components 4 as needed to balance the load distribution of the charging components 4 and further optimize power usage efficiency. At the same time, when the table is folded, in order to avoid the connection to the junction box 41 being affected by the length of the connector 43 or causing excessive stretching of the connector 43, the connector 43 can be unplugged to ensure smooth folding.

[0063] Furthermore, the other side of the junction box 41 is also provided with various types of output interfaces 412. These output interfaces 412 are used to connect to and charge external devices (such as mobile phones, drones, and photography equipment), effectively solving the problem of charging difficulties for users during outdoor activities or emergencies. The output interfaces 412 are diverse, including but not limited to USB-A, USB-C, DC, XT60, and XT90, adaptable to the charging needs of different devices, greatly improving the product's compatibility and convenience.

[0064] In addition, the tabletop 1 is equipped with a wireless charging module 14. The bottom of the tabletop 1 has a recessed groove 15, and the wireless charging module 14 is installed in the groove 15. During use, users only need to place the device in the designated area of ​​the tabletop 1 to connect with the wireless charging module 14 for charging, without having to plug or unplug cables, which further improves the convenience of use and the tidiness of the desktop.

[0065] Preferably, such as Figure 13As shown, to optimize the layout of the wiring on the tabletop 1 and maintain its neat and aesthetically pleasing appearance, a cable management block 23 is provided on the table leg 22. The cable management block 23 has a cable passage hole 231, through which the connecting wire 43 passes to connect with the charging components 4 on the two adjacent tabletops 1. It should be noted that the cable management block 23 has an "L"-shaped structure and is located at the connection between the rotating component 52 and the table leg 22. One side is screwed to the rotating component 52, and the other side is screwed to the table leg 22. The junction box 41 is located beside the crossbeam 21. Therefore, when the connecting wire 43 connects to two adjacent junction boxes 41, its wiring follows the direction of the crossbeam 21, reducing the clutter of the wiring, improving the overall aesthetics and practicality of the product, and effectively preventing tangling, compression, or even damage during folding and unfolding.

[0066] In some embodiments, the tabletop 1 may also be equipped with a Bluetooth / Wi-Fi module, which is integrated into the central power management module and connects to the user's smart device via wireless communication technology. Users only need to download a dedicated app and complete pairing to view real-time information such as the power generation efficiency of the photovoltaic area 11, the remaining power of the energy storage battery, and the operating status of the charging component 4.

[0067] Preferably, to improve the user experience, the tabletop 1 can also be equipped with different functions according to the user's needs, such as integrating LED lighting or ambient light strips, supporting the splicing of multiple tables to form a larger power supply and work platform, or adding anti-slip areas, cup slots or equipment fixing positions on the surface of the tabletop 1, etc.

[0068] The working principle of this invention is explained in detail below:

[0069] When the user needs to unfold the table, simply rotate each rotating component 52 to form a closed-loop structure and secure it with the locking component 51. The table legs 22 will automatically unfold and form a stable table leg structure as the rotating components 52 rotate. Next, rotate the tabletop 1 upward relative to the crossbeam 21 to place the tabletop 1 horizontally. Then, by pulling the connecting component 32 of the locking structure 3 outward and rotating it 90° towards the adjacent tabletop 1, the positioning block 312 engages with the positioning hole 321, thus locking the adjacent tabletop 1 and ensuring that the tabletop remains a horizontal and stable platform in the unfolded state. At this time, the photovoltaic area 11 on the tabletop 1 begins to absorb solar energy and convert it into electrical energy. After optimization by the central power management module, the power is distributed to each charging component 4, providing stable power support for subsequent use.

[0070] When folding and storing, the user simply needs to unlock the connector 32 of the locking structure 3 to release the locking between adjacent tabletops 1, and then rotate the tabletop 1 downwards until it is parallel to the table legs 22. Subsequently, the locking piece 51 is pulled out, and each rotating piece 52 returns to its free-rotating state. The table legs 22 gradually move closer together as the rotating pieces 52 rotate horizontally, ultimately achieving the folding and storage of the tabletop 1. During this process, the photovoltaic area 11 of the tabletop 1 stops working, and the charging component 4 is disconnected, ensuring that the device does not generate additional energy consumption or safety hazards in the stored state. Simultaneously, the user can unplug the connecting cable 43 as needed to prevent the cable from being pulled or damaged during folding, further improving the convenience and safety of storage.

[0071] The innovation of this invention lies in the flexible unfolding and folding of the rotatable and foldable tabletop achieved through the design of the support structure and hinge structure. This not only improves space utilization but also enhances the product's portability. In addition, the photovoltaic area integrated inside the tabletop can efficiently absorb solar energy and store or directly output electrical energy through the central power management module, providing users with sustainable green energy. This not only solves the problem of the single function of traditional solar energy products but also achieves the organic combination of furniture and new energy technology. This makes the product both a high-efficiency solar power generation platform and a practical outdoor table, improving the user experience and enhancing its practicality.
