DETAILED DESCRIPTION

[0037] To clarify the technical problems, technical concepts and advantageous effects of the present application, embodiments of the present application are described below in conjunction with the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12 to Fig. 13 and examples are described in more detail. It should be understood that the specific embodiments described here serve only to illustrate the present application and are not intended to limit its application.

[0038] It should be noted that when an element is described as "attached to" or "arranged on, at, or around" another element, the element may be directly "attached to" or "arranged on, at, or around" another element, or indirectly "attached to" or "arranged on, at, or around" another element. When an element is described as "connected" to another element, it may be directly connected to the other element or indirectly connected to the other element.

[0039] It should be understood that the orientation or positional relationship indicated by the terms "length", "width", "top", "bottom", "front", "back", "left", "right", "vertical", "horizontal", "above", "below", "inside", "outside", etc., is based on the orientation or positional relationship shown in the drawings. The orientation or positional relationship indicated by these terms serves only to facilitate the description of the present application and to simplify its description. It does not constitute an indication or stipulation that the device or element referred to must have a particular orientation or be designed and operated in a particular orientation. Therefore, the orientation or positional relationship indicated by these terms cannot be construed as a limitation of the present application.

[0040] Furthermore, the terms “first”, “second”, etc. are used here for descriptive purposes and cannot be understood as indicating or suggesting a relative importance or as an implicit reference to the number of technical features specified. Therefore, the features defined as “first”, “second”, may explicitly or implicitly include one or more of the features. In the description of this application, “several” means two or more unless expressly defined otherwise.

[0041] Vehicles, such as motor vehicles, are typically used for travel, and various comfort features are usually installed in vehicles to provide comfort to drivers and passengers. For example, a table is placed in the center of the rear seats of some motor vehicles to make it easier for users to work or to allow for entertainment activities in the vehicle.

[0042] To reduce the space required for the tabletop in the vehicle's interior, the tabletop is usually a folding tabletop, and the folding tabletop has a storage form when folded and a usage form when unfolded, and the tabletop can be folded and stored when it is not needed.

[0043] In some conventional motor vehicles, there is usually only a single table, and this table is typically located in the center of the rear seats. This means that the user has to turn their body to access the table, regardless of whether they are sitting in the left or right seat, and the user's waist is prone to fatigue. Prior art designs improve user comfort by providing two fold-down tables. These two fold-down tables are a left-hand table and a right-hand table. The left-hand table can be unfolded and used when the user is sitting in the left-hand seat, and the right-hand table can be unfolded and used when the user is sitting in the right-hand seat.The arrangement of the left and right tabletops allows the user to use the tabletop without turning their body, thus reducing fatigue in the user's waist.

[0044] With a folding table, the tabletop must be unfolded before use and folded down and stored after use. This process consumes a lot of the user's time and energy, making the tabletop inconvenient to use. Therefore, the prior art provides an electric drive element for the tabletop, configured to control the folding and unfolding of the tabletop instead of requiring manual effort. For example, if the user is sitting in the left seat in the rear row, the left electric drive element can unfold the left tabletop, and if the user is sitting in the right seat in the rear row, the right electric drive element can unfold the right tabletop.

[0045] However, the addition of the electric drive element increases the overall size of each folding table, especially in a vehicle with two or more folding tabletops. The two or more folding tabletops take up excessive space in the vehicle, resulting in a cramped interior.

[0046] Based on this, the embodiments of the application provide a folding table, a piece of furniture and a vehicle to solve the prior art technical problem that the folding tabletop takes up excessive space in the motor vehicle, resulting in an overcrowded space in the motor vehicle.

[0047] With reference to the Fig. 1, Fig. 2 to Fig. Section 3 describes the folding table provided in the embodiments of the application.

[0048] The folding table provided in the embodiments of the application comprises a tabletop mechanism and a base 1. The tabletop mechanism comprises a support arrangement 2 and a tabletop 3 arranged on the support arrangement 2. The tabletop 3 is movably connected to the support arrangement 2 to switch the tabletop 3 between a folded-in state and an unfolded state relative to the support arrangement 2. The base 1 is configured to support the tabletop mechanism. The support arrangement 2 is rotatably connected to the base 1 to rotate the tabletop 3 between a first position and a second position relative to the base 1.

[0049] Referring to Fig. 1 The support arrangement 2 can rotate about a first axis S1, so that the support arrangement 2 can rotate relative to the base 1.

[0050] It should be noted that Base 1 can be connected to an external mounting component to provide support and stability. For example, if the folding table is used with a seat, Base 1 can be connected to a body component of the seat to support the tabletop mechanism. Similarly, if the folding table is used with a tea table, Base 1 can be connected to a body component of the tea table.

[0051] It should be noted that the application of the folding table is not limited to the example scenarios mentioned above, and it can also be used in combination with some floor lamps. For example, the folding table can be used in vehicles, such as by storing it in the armrest compartment of a car seat, or by attaching its base to an interior wall of a car and storing the folding table in a cavity within that wall, and so on. The folding table can also be used in furniture, for example, integrated into a sofa, a bedside table, or a floor lamp. Finally, the folding table can be used outdoors, for example, in a recreational area in a park, within an outdoor structure, and so forth.And the scope of application of the folding table is not limited in the embodiments of the application.

[0052] It should be noted that when tabletop 3 is folded, i.e., when not in use, it occupies the smallest possible space and can be stored in a given area. It should also be noted that when tabletop 3 is unfolded, it can provide a surface for the user. For example, the user can place a computer, mobile phone, or similar item on tabletop 3.

[0053] It should be noted that in some embodiments, the rotation angle between the first and second positions can be 180°, 190°, 170°, 90°, etc. The tabletop 3 can be located on the left and right sides of the base 1 in both the first and second positions. In other embodiments, the tabletop 3 can be located on the front and rear sides of the base 1, respectively, in both the first and second positions. In other embodiments, the tabletop 3 can be located on the left side and front sides of the base 1, respectively, in both the first and second positions.

[0054] The support assembly 2 is rotatably connected to the base 1, allowing the tabletop 3 to be adjusted between the first and second positions. This allows the position of the tabletop 3 to be changed according to the user's position. For example, if the user is on the left side of the base 1, the tabletop 3 can be rotated to the left side of the base 1 by the support assembly 2. Conversely, if the user is on the right side of the base 1, the tabletop 3 can be rotated to the right side of the base 1 by the support assembly 2. Thus, the position of the tabletop 3 can be adjusted according to the user's actual position, allowing the user to use the tabletop 3 comfortably.Since the tabletop 3, together with the support assembly 2, can be rotated to adjust its position, the single tabletop 3 can meet usage requirements when the user is in different positions. Therefore, the folding tabletop 3 can be equipped with only a single tabletop, reducing the volume of the folding table, thus minimizing the space it occupies, reducing clutter, and creating a more spacious environment.

[0055] In some embodiments, the folding table can be attached to a rear seat of a motor vehicle, and the folding table is positioned in the center of the rear seat. When a user is seated in the left seat, the tabletop mechanism can be set in the unfolded position and in the first position (referring to Fig. 1) can be arranged. When the user is seated on the right, the tabletop mechanism can be rotated 180° around the first axis S1 in the first position to be in the second position (referring to Fig. 2) to be ordered.

[0056] The folding table further comprises a first drive mechanism 4, which is mounted on the base 1. The first drive mechanism 4 is driven by a force connected to the support assembly 2 to cause the support assembly 2 to rotate relative to the base 1, thereby causing the tabletop 3 to rotate into the first or second position. The first drive mechanism 4 can drive the support assembly 2 to rotate, thus causing the tabletop 3 to rotate automatically between the first and second positions. Therefore, the position of the tabletop 3 can be adjusted without manually operating the folding table, thereby reducing the difficulties of using the folding table and improving user comfort.

[0057] In this embodiment, the driving force of the first drive mechanism 4 acts on the support arrangement 2, and the support arrangement 2 rotates under the driving force to cause the tabletop 3 to rotate. That is, the driving force of the first drive mechanism 4 does not act directly on the tabletop 3. Therefore, the first drive mechanism 4 can be located away from the tabletop 3. In this way, the space occupied by the first drive mechanism 4 can be reduced when the tabletop 3 is unfolded. For example, if the folding table is attached to a seat, the first drive mechanism 4 can always be housed within the seat's body component. Whether the tabletop 3 is unfolded or folded, the position of the first drive mechanism 4 does not change. The first drive mechanism 4 is not exposed to the external environment when the tabletop 3 is unfolded.Therefore, the occupancy of the surrounding space by the first drive mechanism 4 can be reduced.

[0058] It should be noted that either the unfolding of tabletop 3 or, when tabletop 3 is unfolded, encompasses the process of unfolding tabletop 3 and the period during which tabletop 3 is held in the unfolded state. The tabletop 3 of the in Fig. The folding table shown in Figure 1 is in its unfolded state.

[0059] In some embodiments, the tabletop 3 is switched between the extended and folded positions by an electric drive. Therefore, the folding table can be used even more conveniently by the user.

[0060] In some embodiments, the first drive mechanism 4 comprises a first drive element 41 and a first gear assembly connected to the first drive element 41. One part of the first drive element 41 and the first gear assembly is connected to the base 1, and the other part is connected to the support assembly 2. The first drive element 41 and the first gear assembly are interconnected, and the first drive element 41 can be connected to either the base 1 or the support assembly 2 via the first gear assembly. The first gear assembly can adjust the direction of the drive force of the first drive element 41, thereby facilitating the installation of the first drive element 41 and saving space, thus reducing the volume of the folding table.The first gear assembly can adjust the rotational speed of the support assembly 2, thus controlling its rotational speed within a reasonable range and improving the stability of its rotation. Furthermore, the first gear assembly can also change the direction of the drive force, simplifying the design of the installation position for the first drive element 41 and saving space occupied by the folding table.

[0061] In some embodiments, the first drive element 41 can be a motor.

[0062] Referring to Fig. In some embodiments, the first gear arrangement comprises a worm gear 423 and a worm (not shown) that meshes with the worm gear 423. The worm is connected to an output shaft of the first drive element 41, and the worm gear 423 is connected to the support arrangement 2. The combination of the worm gear 423 and the worm can have a large gear ratio and a compact structure, thus reducing the size of the first gear arrangement. Line contact exists between the meshing tooth flanks of the worm gear 423 and the worm, providing high load-bearing capacity and thereby contributing to improved stability of the first gear arrangement. A worm drive is essentially a screw drive.The worm and the worm wheel 423 are in a multi-toothed, meshing transmission relationship, ensuring a stable transmission relationship and quiet operation of the worm drive. The worm wheel 423 and the worm are self-locking. If the helix angle of the worm is smaller than the equivalent friction angle between the meshing teeth, only the worm can drive the worm wheel 423, and the worm wheel 423 cannot drive the worm. This ensures the protection of the first drive element 41. In this embodiment, the first drive element 41 can be arranged on the base 1.

[0063] Referring to Fig. In other embodiments, the first gear arrangement comprises a first gear 421 and a ring gear 422, wherein the first gear 421 engages with teeth arranged on the inner circumferential surface of the ring gear 422, the first gear 421 is connected to the output shaft of the first drive element 41, and the ring gear 422 is connected to the base 1. The first gear arrangement, comprising the ring gear 422 and the first gear 421, has a high reduction ratio and low vibration and can enable stable rotation of the tabletop mechanism.

[0064] In some other embodiments, the first gear arrangement comprises a second gear (not shown) and a third gear (not shown), wherein the second gear engages with teeth arranged on the outer circumferential surface of the third gear, the second gear is connected to the output shaft of the first drive element 41, and the third gear is connected to the support arrangement 2. In this embodiment, the first drive element 41 may be arranged on the base 1 or the support arrangement 2, and the connection type of the third gear and the support arrangement 2 may be as described in the embodiments above; and the second gear and the third gear may be spur gears or bevel gears.

[0065] In some embodiments, the support arrangement 2 comprises a rotary component 21 rotatably mounted on the base 1 and a support component 22 arranged on the rotary component 21. The tabletop 3 is arranged on the support component 22, and the rotary component 21 is able to rotate relative to the base 1, thereby causing the support component 22 to rotate so that the tabletop 3 switches between the first position and the second position. Referring to Fig. 1. The tabletop 3 is in its unfolded state and in the first position. Referring to Fig. In section 2, the tabletop 3 is in its unfolded state and in the second position. The tabletop 3 can rotate 180° around the first axis S1 from the first position to the second position. The support component 22 is arranged on the rotating component 21. The rotating component 21 can be considered an extension of the support component 22. This facilitates the connection between the support assembly 2 and the base 1, improves the connection stability between the support assembly 2 and the base 1, and enhances the stability of the tabletop 3 during use.

[0066] For example, the base 1 can be provided with a first plate 11, the rotating component 21 can be constructed as a plate structure, and the rotating component 21 can be rotatably attached to the first plate 11.

[0067] For example, the first drive mechanism 4 can be connected to the rotary component 21 or the first plate 11.

[0068] Referring to Fig. In some embodiments, the first gear arrangement comprises a worm gear 423 and a worm (not shown in the figure) that engages with the worm gear 423. The worm gear 423 is arranged on a side of the first plate 11 facing away from the rotating component 21. A first clearance hole 114 may be formed in the center of the first plate 11, and the worm gear 423 may be connected to the rotating component 21 using a first connecting element 16 that projects through the first clearance hole 114.

[0069] Referring to Fig. 7 The first gear arrangement comprises, in some embodiments, a first gear 421 and a ring gear 422 which meshes with the first gear 421. The first drive element 41 can be arranged on the support arrangement 2. The center of the rotating part 21 and the center of the first plate 11 can be rotatably connected by means of a connecting shaft 14. The ring gear 422 and the first gear 421 can be arranged on one side of the first plate 11 facing the rotating component 21. The ring gear 422 and the first gear 421, which are in Fig. 7 are shown, are arranged on a side of the first plate 11 facing away from the rotating component 21, a second escape hole can be arranged in the first plate 11, and the first gear 421 can be connected to the rotating component 21 by using a second connecting element that protrudes through the second escape hole.

[0070] Referring to Fig. 1 The tabletop 3 comprises two rotatably connected plate bodies 31 and an arm body 32 that connects the two plate bodies 31 to the support component 22. When the tabletop 3 is in the unfolded state, the two plate bodies 31 can be moved as shown in Fig. 1 shown unfolded, and the arm body 32 and the support component 22 can be arranged vertically. If it is necessary to fold the folding table, the plate body 31 can be folded around the area shown. Fig. 1 the second axis S2 shown can be rotated so that the two plate bodies 31 are placed on top of each other to form the one shown in part (a) of Fig. to form the state shown in section 4. The two superimposed plate bodies 31 can be rotated about the third axis S3, which is shown in part (a) of Fig. 4 is shown to illustrate the one in part (b) of Fig. to form the state shown in section 4. The arm body 32 can be extended by the section shown in part (b) of Fig. The fourth axis S4 shown in section 4 can be folded upwards to accommodate the axis shown in part (c) of Fig. to form the state shown in section 4. In part (c) of Fig. 4 the tabletop 3 is in the folded state, the support component 22 can be extended by the part shown in part (c) of Fig. The fifth axis S5 shown in section 4 is rotated to align with the axis shown in part (d) of Fig. The tabletop 3 is in part (d) of the state shown in section 4. Fig. 4 not shown.

[0071] It should be noted that the in Fig. 4 The rotation of the plate body 31, the arm body 32 and the support component 22 shown can be carried out one after the other or simultaneously.

[0072] Referring to the Fig. 5 and Fig. In Figure 7, base 1 is provided with a first limiting component 151 and a second limiting component 152, and the rotary component 21 is provided with a third limiting component 214. When the tabletop 3 is in the first position, the third limiting component 214 rests against the first limiting component 151. When the tabletop 3 is in the second position, the third limiting component 214 rests against the second limiting component 152. The first limiting component 151 and the second limiting component 152 on base 1 interact with the third limiting component 214 on the rotary component 21. The rotation angle of the rotary component 21 can be limited in such a way that the surface contact forms a rotation lock. The possibility of positional deviation of the tabletop 3 caused by an excessive rotation angle of the rotary component 21 can be reduced.In this way, the distance between the tabletop 3 and the user can be ensured, and comfort when using the tabletop 3 can be guaranteed.

[0073] For example, the first boundary component 151 and the second boundary component 152 can be arranged on the first plate 11 of the base 1.

[0074] Referring to the Fig. 5 and Fig. In some embodiments, the base 1 is provided with a limiting groove 15. The limiting groove 15 is arranged around the axis of rotation of the rotating component 21. The third limiting component 214 is slidably arranged in the limiting groove 15. The inner side walls of the two ends of the limiting groove 15 in the longitudinal direction form the first limiting component 151 and the second limiting component 152, respectively. The third limiting component 214 is inserted into the limiting groove 15 to create the sliding connection between the third limiting component 214 and the limiting groove 15. In this way, the difficulty of assembling the rotating component 21 and the base 1 can be reduced, and the efficiency of assembling the folding table can be improved.

[0075] The limiting groove 15 can, for example, be arranged on the first plate 11 of the base 1. It should be noted that the bottom of the limiting groove 15 can penetrate a side surface of the first plate 11 facing away from the rotating component 21. Fig. 5 and Fig. Figure 7 shows that the limiting groove 15 penetrates a side surface of the first circuit board 11 facing away from the rotating component 21.

[0076] The rotation angle of the tabletop 3 is, for example, 180°. Thus, the center angle, which corresponds to the arc-shaped limit groove 15, can be set to 180°.

[0077] Referring to the Fig. 7. The third limiting component 214 can also serve as a second connecting element to connect the first gear 421 and the rotating component 21 in the embodiments described above. The limiting groove 15 can also serve as a second escape hole to avoid the second connecting element in the embodiments described above. The bottom of the limiting groove 15 penetrates a side surface of the first plate 11 facing away from the rotating component 21.

[0078] Referring to the Fig. 3, Fig. 8 and Fig. In Figure 9, the base 1 is provided with a first locking component 112 and a second locking component 113, and the pivot component 21 is provided with a third locking component 212. When the tabletop 3 is in the first position, the first locking component 112 can be engaged with the third locking component 212 to limit the rotation of the pivot component 21. When the tabletop 3 is in the second position, the second locking component 113 can be engaged with the third locking component 212 to limit the rotation of the pivot component 21. It can be understood that the folding table can be pushed by an external force during use, and the pivot component 21 tends to move relative to the base 1, resulting in a positional deviation of the tabletop 3.The first locking component 112 is located on the base 1, and the third locking component 212 is located on the pivot component 21. When the tabletop 3 is in the first position, the first locking component 112 can be engaged with the third locking component 212, thus limiting the relative rotation between the pivot component 21 and the base 1 and holding the tabletop 3 in the first position. Similarly, the second locking component 113 on the base 1 and the third locking component 212 on the pivot component 21 can hold the tabletop 3 in the second position, thereby improving the stability of the folding table and reducing the possibility of the tabletop 3 rotating due to a collision with an external force during use.

[0079] For example, the first locking component 112 and the second locking component 113 can be arranged on the first plate 11.

[0080] With reference to the Fig. 8 and Fig. In some embodiments, the first locking component 112 and the second locking component 113 are locking holes defined in the base 1, and the third locking component 212 is a locking pin slidably mounted on the rotary component 21. When the locking pin is in a locked state, it is inserted into the locking holes. When the locking pin is in an unlocked state, it is separated from the locking holes. The first locking component 112 and the second locking component 113 are designed as locking holes, and the third locking component 212 is designed as a locking pin, thus simplifying the structure of the three components and reducing the machining difficulty of the rotary component 21 and the base 1.Furthermore, the rotary component 21 and the base 1 can be locked by moving the locking pin and adopting a plug-in cooperation mode, which allows convenient control of the locking and unlocking between the rotary component 21 and the base 1.

[0081] For example, the first locking component 112 and the second locking component 113 can be locking holes defined in the first plate 11.

[0082] In some other embodiments, the first locking component 112 and the second locking component 113 can use magnets. The third locking component 212 can use an electromagnet. Alternatively, the first locking component 112 and the second locking component 113 can use electromagnets, and the third locking component 212 can use a magnet. Alternatively, the first locking component 112, the second locking component 113, and the third locking component 212 can all use electromagnets. In these embodiments, the first locking component 112 and the second locking component 113 are locked to the third locking component 212 by magnetic attraction, and when unlocking is required, the electromagnets can be switched off.

[0083] Referring to the Fig. In sections 3 and 9 to 11, the locking pin comprises a connecting component 2121, which is connected to the support arrangement 2, and a fastening component 2122 for insertion into the locking holes. The connecting component 2121 is located on the side of the rotating component 21 facing away from the base 1. The rotating component 21 is provided with a through-hole 215, and the fastening component 2122 can be inserted through the through-hole 215 into the locking holes. The connecting component 2121 is located on the side of the rotating component 21 facing away from the base 1. The connecting component 2121 does not occupy the space between the rotating component 21 and the base 1, thus reducing the distance between the rotating component 21 and the base 1. This allows the base 1 to stably support the rotating component 21, i.e., the support stability of the base 1 for the rotating component 21 is improved.The through hole 215 is arranged on the rotary component 21, and when the fastening component 2122 is simultaneously inserted into the through hole 215 and the locking holes, the rotary component 21 can be locked to the base 1, in which case the rotary component 21 cannot rotate relative to the base 1, so that the table top 3 can be held in the first position or the second position.

[0084] For example, the connecting component 2121 can be arranged on a side of the rotating component 21 facing away from the first plate 11.

[0085] In some embodiments, the tabletop mechanism further comprises a second drive mechanism 5 for driving the tabletop 3 to switch between the folded-in state and the unfolded state, wherein the second drive mechanism 5 is connected to the tabletop 3 or the third locking component, and when the second drive mechanism 5 drives the tabletop 3 to switch from the folded-in state to the unfolded state, the third locking component 212 is synchronously driven by the second drive mechanism 5 to move such that the third locking component 212 is connected to the first locking component 112 or the second locking component 113.The second drive mechanism 5 is designed to drive the tabletop 3 to change from the folded state to the unfolded state, and to synchronously drive the fastening component 2122 to insert it into the locking holes; the third locking component 212 can move synchronously during the process of rotating and unfolding the arm body 32, so that a connection between the two can be realized; and the locking pin can lock the rotating component 21 during the process of unfolding and using the tabletop mechanism.Furthermore, the driving force for switching the tabletop 3 between the folded and unfolded states and the driving force for moving the third locking component 212 both come from the second drive mechanism 5, and no additional drive mechanism is required to drive the third locking component 212 to move, so that the number of drive mechanisms in the folding table can be saved, which helps to save space for the folding table, reduce the volume of the folding table and reduce the occupancy of space in the vehicle.

[0086] In some embodiments, the second drive mechanism 5 can drive the arm body 32 to rotate about the fourth axis S4 in order to adjust the enclosed angle between the arm body 32 and the support component 22, and drive the two plate bodies 31 to rotate so that the table top 3 can be switched between the folded state and the unfolded state.

[0087] In some embodiments, the third locking component 212 is a locking pin, the locking pin comprising a connecting component 2121, which is connected to the support arrangement 2, and a fastening component 2122, which is to be inserted into the locking holes. When the locking pin is in the unlocked state, the connecting component 2121 and the fastening component 2122 are spaced apart from each other. When the locking pin switches from the unlocked state to the locked state, the connecting component 2121 moves toward the fastening component 2122 and pushes the fastening component 2122 to insert it into the locking holes. It can be understood that the folding table can be pushed or nudged by an external force during use, the direction of the external force typically being from the first axis S1 (i.e.,the axis of rotation of the rotary component 21) deviates. Thus, the external force has a torsional effect, and the support component 22 can be easily twisted. While it serves as the locking pin for locking the rotary component 21 and the base 1, the locking pin is highly likely to break under torsion. The connecting component 2121 and the fastening component 2122 are spaced apart from each other, i.e., the connecting component 2121 and the fastening component 2122 are designed as independent parts. Since the connecting component 2121 is connected to the support component 22, the connecting component 2121 is also subjected to external forces from impacts or thrusts when the folding table is in use.However, since the connecting component 2121 and the fastening component 2122 are in contact with each other, even if the support component 22 is twisted, the connecting component 2121 and the fastening component 2122 can be displaced, so that the torsion transmitted to the fastening component 2122 can be reduced, the possibility of breakage of the fastening component 2122 can be reduced and the reliability of the locking pin can be improved.

[0088] For example, the connecting component 2121 can be driven by the second drive mechanism 5 to move towards the fastening component 2122, so that the connecting component 2121 pushes against the fastening component 2122 and presses the fastening component 2122 to be inserted into the locking holes.

[0089] In this example, the fastening component 2122 of the locking pin can be connected to the rotary component 21, and the connecting component 2121 of the locking pin can be connected to the support component 22.

[0090] In other embodiments, the connecting component 2121 and the fastening component 2122 can be rigidly connected to each other, i.e., the connecting component 2121 and the fastening component 2122 are connected as a single unit. Alternatively, other design arrangements can be made to eliminate the influence of torsion on the fastening component 2122. For example, a spring can be arranged between the connecting component 2121 and the second drive mechanism 5, so that the connecting component 2121 can be displaced relative to the second drive mechanism 5.

[0091] In some embodiments, one of the connecting component 2121 and the fastening component 2122 is provided with a fixing element 2123, while the other of the connecting component 2121 and the fastening component 2122 is provided with a fixing hole 2124. When the connecting component 2121 abuts the fastening component 2122, the fixing element 2123 is inserted into the fixing hole 2124. In this embodiment, with reference to Fig. 10. The fixing element 2123 is arranged on the connecting component 2121, and the fixing hole 2124 is arranged on the fastening component 2122. In other embodiments, the fixing element 2123 can be arranged on the fastening component 2122, and the fixing hole 2124 can be arranged on the connecting component 2121. The fixing element 2123 and the fixing hole 2124 are arranged between the connecting component 2121 and the fastening component 2122, so that the fixing element 2123 and the fixing hole 2124 can be connected in a pluggable manner to improve the stability of the connection. In this embodiment, the fixing hole 2124 is a blind hole, i.e., the fixing hole 2124 does not penetrate through the fastening component 2122, so that the influence on the strength of the fastening component 2122 can be reduced.

[0092] In some embodiments, the size of one end of the fixing element 2123 can be smaller than the size of the root of the fixing element 2123 (i.e., when the connecting component 2121 and the fastening component 2122 are separate, the size of one end of the fixing element 2123 near the fixing hole 2124 is smaller than the size of one end of the fixing element 2123 farther from the fixing hole 2124). The opening of the fixing hole 2124 is trumpet-shaped so that the fixing element 2123 can be inserted snugly into the fixing hole 2124.

[0093] Referring to Fig. 9 The support device 2 is further provided with an elastic element 23. The elastic element 23 is connected to the fastening component 2122 to drive the fastening component 2122 to release itself from the locking hole. When the tabletop 3 is moved from the extended to the folded position, the fastening component 2122 can move to one side away from the locking hole under the elastic force of the elastic element 23, thus disengaging from the locking hole and resetting itself. In this way, the lock between the rotating component 21 and the base 1 is released, and the rotating component 21 can rotate relative to the base 1 to achieve the position adjustment of the tabletop 3. In some embodiments, the elastic element 23 can be a spring, a rubber pad, or the like.

[0094] For example, the connecting component 2121 is driven by the second drive mechanism 5, and when the second drive mechanism 5 drives the connecting component 2121 to move it away from the fastening component 2122, the fastening component 2122 can separate from the locking hole to reset itself under the elastic force of the elastic element 23 in order to release the locking between the rotating component 21 and the base 1, so that the rotating component 21 can rotate relative to the base 1 to realize the position adjustment of the tabletop mechanism.

[0095] Referring to the Fig. 9 and Fig. In section 11, the support device 2 is provided with a guide component 221. The guide component 221 is connected to the locking pin and configured to guide the movement of the locking pin. The guide component 221 can guide the direction of movement of the locking pin such that the locking pin moves in a direction parallel to the one in Fig. 1 can move the first axis S1 shown and the locking pin can be inserted into the locking hole to realize the locking between the rotary component 21 and the base 1.

[0096] In some embodiments, the guide component 221 is a second slot 2211 arranged on the rotary component 21. With reference to the Fig. 9 and Fig. The rotating component 21 is provided with a mounting column 213 on a side surface facing away from the first plate 11, and the second slot 2211 is a slot structure recessed from an end surface of the mounting column 213, and the fastening component 2122 of the locking pin is in sliding contact with the second slot 2211. The second slot 2211 is configured to guide the movement of the fastening component 2122. The elastic element 23 can be arranged in the second slot 2211. For example, one end of the elastic element 23 can be connected to the fastening component 2122, and the other end of the elastic element 23 is connected to a side wall of the second slot 2211. The fastening component 2122 can, for example, be L-shaped. In this way, the fastening component 2122 can be appropriately connected to the second slot 2211.

[0097] Several second slots 2211, for example two, can be provided. Similarly, several elastic elements 23, for example two, can be provided. The fixing hole 2124 on the fastening component 2122 can be arranged between the two second slots 2211. In this way, the stress on the fastening component 2122 can be balanced, and the jamming phenomenon during movement of the fastening component 2122 can be reduced.

[0098] In some other embodiments, the guide component 221 is a second slide rail 2212 arranged on the support component 22. Referring to Fig. 12. The connecting component 2121 of the locking pin is in sliding contact with the second slide rail 2212. In this way, the second slide rail 2212 is configured to guide the movement of the connecting component 2121. The folding table can be provided with either the second slot 2211 or the second slide rail 2212.

[0099] The support component 22 comprises a housing 222 connected to the rotary component 21. Part of the third locking component 212 is located within an enclosed area of ​​the housing 222 and the rotary component 21. By locating part of the third locking component 212 within this enclosed area, the housing 222 protects the third locking component 212, thereby reducing the risk of accidental unlocking. Unintentional unlocking occurs when the third locking component 212, in its locked state, is separated from the first locking component 112 or the second locking component 113 due to an external collision.

[0100] If the third locking component 212 is, for example, a locking pin, part of the locking pin can be located within the enclosed area of ​​the housing 222 and the rotating component 21. For example, the connecting component 2121 and part of the fastening component 2122 of the locking pin can be located within the enclosed area of ​​the housing 222 and the rotating component 21.

[0101] For example, the guide component 221 can also be arranged in the housing 222. If the guide component 221 is, for example, the second slide rail 2212, the second slide rail 2212 can be formed integrally with the housing 222, or the second slide rail 2212 and the housing 222 can be two separate parts that are joined together by gluing or using fasteners.

[0102] Referring to the Fig. 3, Fig. 9 and Fig. 12 The housing 222 comprises a housing cover 2221 and several housing plates 2222. The housing plates 2222 are attached to the rotating component 21, the housing cover 2221 is arranged around the circumference of the support component 22, and the housing cover 2221 is rotatably connected to the housing plates 2222 so that the support component 22 can rotate about the fifth axis S5.

[0103] In some embodiments, the second drive mechanism 5 comprises a second drive element 51 and a second gear assembly. The second gear assembly comprises a threaded rod 521 connected to an output shaft of the second drive element 51 and a movable block 522 slidably mounted on the support assembly 2, the movable block 522 being threaded to the threaded rod 521 and the third locking component 212 being connected to the movable block 522. The threaded rod 521 and the movable block 522 of the second gear assembly can convert the torque provided by the second drive element 51 into the force for the linear movement of the third locking component 212.When the second drive element 51 is started, the threaded rod 521 rotates together with the output shaft of the second drive element 51, and the movable block 522 is connected to the third locking component 212, thereby driving the third locking component 212 into a linear motion. In some embodiments, the second drive element 51 can be an electric motor, an internal combustion engine, or the like. An output shaft of the second drive element 51 can rotate, and the second gear assembly can convert the rotary motion into a linear motion.

[0104] The third locking component 212 is, for example, a locking pin, and the movable block 522 can be connected to a connecting component of the locking pin. When the second drive element 51 is started, the threaded rod 521 rotates together with the output shaft of the second drive element 51, and the movable block 522 is connected to the connecting component 2121, and the connecting component 2121 is in sliding contact with the housing cover 2221. Thus, the rotary motion of the threaded rod 521 can be converted into a linear motion of the movable block 522, which drives the connecting component 2121 to move up and down, and drives the locking pin to be inserted into the locking holes to lock the connecting component 21 and the first plate 11.

[0105] In other embodiments, a rack and pinion structure can be configured to convert the rotary motion of the output shaft of the second drive element 51 into a linear motion. For example, a pinion of the rack and pinion structure can be connected to the output shaft of the second drive element 51, and a rack of the rack and pinion structure can be connected to the connecting component 2121.

[0106] In the embodiments of the present application, the second drive mechanism 5 can, for example, also drive the arm body 32 to rotate about the fifth axis S5. The second drive mechanism 5 further comprises a third drive element 53 and a third gear assembly, wherein the third drive element 53 and the third gear assembly can be mounted on a housing plate 2222. The third drive element 53 can be an electric motor. The third gear assembly comprises a fourth gear (not shown in the figure) and a sector gear 54. The fourth gear is connected to an output shaft of the third drive element 53. The sector gear 54 is connected to the housing cover 2221.The force from the third drive element 53 is transmitted via the fourth gear and the sector gear 54 to the housing cover 2221, which in turn drives the housing cover 2221 to rotate the support component 22 about the fifth axis S5. The support component 22 and the housing cover 2221 rotate as a unit.

[0107] With reference to the Fig. 1 and Fig. The movable block 522 is connected to the arm body 32 via a sliding plate 223. The two ends of the sliding plate 223 are articulated to both the sliding plate 223 and the arm body 32, and the arm body 32 is articulated to the housing 2221 of the support component 2. Thus, the position of the sliding plate 223 changes during the linear movement of the movable block 522, causing the arm body 32 to rotate and thereby enabling the opening and closing of the tabletop 3.

[0108] It should be noted that several drive elements and gear arrangements can also be arranged in the second drive mechanism 5 to drive the plate body 31 of the table top 3 to rotate about the second axis S2 and to drive the table top 3 to rotate about the third axis S3.

[0109] Referring to Fig. 6 is provided with a first slide rail 111 between the base 1 and the rotating component 21, and the other is provided with a slide block 211 between the base 1 and the rotating component 21. The first slide rail 111 is arranged around the axis of rotation of the rotating component 21, and the rotating component 21 is rotated relative to the base 1 by sliding the slide block 211 with the first slide rail 111. The in Fig. Figure 6 shows a first guide rail 111 arranged on the base 1, and the sliding block 211 arranged on the rotary component 21. In other embodiments, the sliding block 211 can be arranged on the base 1, and the first guide rail 111 on the rotary component 21. A first guide rail 111 and a sliding block 211, which are slidably connected to each other, are each arranged on the base element 1 and the rotary assembly 21, respectively. The combined use of the first guide rail 111 and the sliding block 211 is configured to guide the relative movement between the rotary component 21 and the base element 1, thereby reducing the possibility of deviation in the direction of rotation of the rotary component 21 and thus improving the stability of the folding table.

[0110] The first slide rail 111 can, for example, be arranged on the first plate 11 of the base 1.

[0111] In some embodiments, the sliding block 211 is ring-shaped. Thus, the first sliding rail 111 can be in contact with the sliding block 211 at all positions, thereby improving the rotational stability of the rotating component 21 and the stability of the folding table.

[0112] In other embodiments, the sliding block 211 is one of several sliding blocks 211, and the several sliding blocks 211 are arranged at intervals around the axis of rotation of the rotating component 21. Thus, the frictional force generated by the first sliding rail 111 and the sliding block 211 can be compensated for by increasing the number of sliding blocks 211, thereby improving the rotational stability of the rotating component 21 and the stability of the folding table.

[0113] With reference to Fig.In some embodiments, the first slide rail 111 is arranged on the first plate 11, and the first slide rail 111 is a first slot recessed into the surface of the first plate 11. The slide block 211 is arranged on the rotating component 21; the slide block 211 is a projecting block that extends from the surface of the rotating component 21, and the projecting block is slidably arranged in the first slot. In other embodiments, the first slide rail 111 is arranged on the rotating component 21; the first slide rail 111 is a first slot recessed into the surface of the rotating component 21. The slide block 211 is arranged on the first plate 11; the slide block 211 is a projecting block that extends from the surface of the first plate 11, and the projecting block is slidably arranged in the first slot.The first slide rail 111 is designed as a slotted structure, and the slide block 211 is designed as a protruding structure, thus simplifying the structures of the first slide rail 111 and the slide block 211, thereby reducing the machining difficulties of both. Furthermore, the sliding assembly of the slide block 211 and the first slide rail 111 can be achieved by inserting the slide block 211 into the first slide rail 111, thereby reducing the assembly effort of both and improving the assembly efficiency of the folding table.

[0114] In some embodiments, the thickness of the edge region of the first plate 11 can be locally increased to facilitate the formation of the first slot.

[0115] In some embodiments, the first slide rail 111 can be formed integrally with the first plate 11, i.e., the first slide rail 111 and the first plate 11 have no join or assembly marks. This improves the stability of the connection between the first slide rail 111 and the first plate 11. The slide block 211 can be formed integrally with the rotating component 21, i.e., the slide block 211 and the rotating component 21 have no join or assembly marks. This improves the connection stability between the slide block 211 and the rotating component 21.

[0116] Referring to Figures 6 to 9, the base 1 is provided with an annular surrounding wall 12, the annular surrounding wall 12 being arranged around the edge of the rotating component 21. The annular surrounding wall 12 is arranged at the base 1, and the rotating component 21 is arranged within the enclosed area of ​​the annular surrounding wall 12, so that the annular surrounding wall 12 can provide protection for the rotating component 21 and reduce the probability of abrasion caused by other parts in the vicinity that collide with the rotating component 21.

[0117] The ring-shaped surrounding wall 12 can, for example, be arranged on the first plate 11 of the base 1.

[0118] The inner side wall of the annular surrounding wall 12 is provided with a fourth limiting component 121, the fourth limiting component 121 being configured to abut a side of the rotating component 21 facing away from the base 1. In this way, the fourth limiting component 121 can limit a relative distance between the rotating component 21 and the base 1, and the fourth limiting component 121 can provide a limit for the rotating component 21 in the direction parallel to the first axis S1 to prevent the rotating component 21 from moving towards a side away from the base 1, thereby reducing the risk of the rotating component 21 becoming separated from the base 1.Furthermore, the fourth limiting component 121 can rest against the rotating component 21 if the rotating component 21 bounces during rotation, so that the rotating component 21 can rotate evenly, thereby improving the rotational stability of the tabletop mechanism.

[0119] In some embodiments, the side of the first plate 11 facing away from the rotating component 21 may further be provided with a second plate 13, and the second plate 13 may be attached to an external device by means of a fastening means, such as a screw, in order to achieve the assembly of the folding table and the external device.

[0120] It should be noted that the folding table in each of the above embodiments can be used not only in a motor vehicle, but also in a vehicle such as an aircraft, a ship, etc. The folding table is not limited to being mounted on a seat, but can be mounted in any suitable location. The folding table in each of the above embodiments can also be used as a piece of furniture; for example, the folding table can be used in a living area, an office building, a shopping mall, or the like. The folding table in each of the above embodiments can also be used outdoors. Furthermore, the scope of application and the mounting position of the folding table are not limited in the embodiments of the application.

[0121] It should be noted that the base 1 can be equipped with a control unit (not shown in the figures), and two opening buttons (not shown in the figures) can each be arranged on opposite sides of the base 1. The opening buttons are connected to the control unit, which can be connected to all drive elements of the folding table. A user can press any of the opening buttons.
