[0056] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer, the following further describes the present application in detail with reference to the accompanying Figures 1 to 13 drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0057] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0058] It should be understood that the orientation or positional relationship indicated by terms such as "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0059] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, the meaning of "a plurality" is two or more, unless otherwise specifically defined.

[0060] Vehicles led by cars are commonly used means of transportation for people, and various convenience devices for providing convenience to drivers and passengers are usually installed inside the vehicle. For example, a table board is configured in the middle of the rear seats of some cars to facilitate users to work or engage in entertainment activities in the car.

[0061] To reduce the occupation of the interior space of the vehicle by the table board, the table board is usually a folding table board. The folding table board has a storage form after being folded and a use form after being unfolded. When the table board is not needed, the table board can be folded and stored.

[0062] For some ordinary cars, usually only one table board is provided inside the vehicle, and the table board is usually set in the middle position of the rear seats. Therefore, no matter whether the user sits on the left seat or the right seat, the user needs to lean sideways to use the table board, which easily causes fatigue in the user's waist. In the related art, to improve the user's use comfort, two folding table boards are provided. The two folding table boards are the left table board and the right table board respectively. When the user sits on the left rear seat, the left table board can be unfolded and used. When the user sits on the right seat, the right table board can be unfolded and used. The setting of the left table board and the right table board can enable the user not to lean sideways when using the table board and reduce the fatigue of the user's waist.

[0063] For the folding table board, before and after use, it needs to be unfolded and folded and stored. This process consumes a lot of time and energy of the user, resulting in inconvenience in using such a table board. Therefore, in the related art, by configuring an electric driving member for the table board, the electric driving member is used to drive the folding and unfolding of the table board instead of manual labor. For example, when the user sits on the left rear seat, the electric driving member on the left can drive the left table board to unfold. When the user sits on the right rear seat, the electric driving member on the right can drive the right table board to unfold.

[0064] However, the addition of the electric drive component increases the overall size of each folding table board. Especially for vehicles equipped with two or more folding table boards, the folding table boards occupy too much space inside the vehicle, resulting in a crowded interior space.

[0065] Based on this, the embodiments of the present application provide a folding table board, furniture, and a means of transportation to solve the technical problem in the prior art that the folding table board occupies too much space inside the vehicle, resulting in a crowded interior space.

[0066] Please refer to Figures 1 to 3 together to illustrate the folding table board provided by the embodiments of the present application.

[0067] The embodiments of the present application provide a folding table board, including a table board mechanism and a base 1. Among them, the table board mechanism includes a support component 2 and a table board 3 provided on the support component 2. The table board 3 is movably connected to the support component 2 so that the table board 3 can be switched between a folded state and an unfolded state relative to the support component 2. The base 1 is used to carry the table board mechanism, and the support component 2 is rotatably connected to the base 1 so that the table board 3 can rotate between a first position and a second position relative to the base 1.

[0068] Referring to Figure 1 , the support component 2 can rotate around the first axis S1, thereby causing relative rotation with the base 1.

[0069] It should be noted that the base 1 can be connected to an external fixing member to play a role of fixed support. For example, when the folding table board is applied to a seat, the base 1 can be connected to the main body of the seat to provide support for the table board mechanism; again, when the folding table board is applied to a tea table, the base 1 can be connected to the main body of the tea table.

[0070] It should be noted that the application fields of the folding table board are not limited to the scenarios in the above examples. The folding table board can also be used in combination with some floor lamps. Exemplarily, the folding table board can be applied in the field of means of transportation. For example, the folding table board can be stored in the armrest box of the seat of the means of transportation, or the base can be connected to the inner wall of the carriage. When the folding table board is in the folded state, it can be received in the cavity of the inner wall of the carriage, etc.; the folding table board can be applied in the field of furniture, such as sofas, bedside tables, floor lamps, etc. in the furniture field; the folding table board can be applied outdoors, such as in the leisure area of the park, outdoor construction scaffolds, etc.; the embodiments of the present application do not limit this here.

[0071] It should be noted that when the table board 3 is in the folded state, the table board 3 is not in use. At this time, the folding table board occupies the smallest space and can be received in a certain space; when the table board 3 is in the unfolded state, the table board 3 of the folding table board can form a bearing surface for users to use. For example, users can place items such as computers and mobile phones on the table board 3.

[0072] It should be noted that in some embodiments, the rotation angle between the first position and the second position can be 180°, 190°, 170°, 90°, etc.; the tabletop 3 can be located on the left and right sides of the base 1 at the first position and the second position respectively. In some other embodiments, the tabletop 3 can be located on the front and rear sides of the base 1 at the first position and the second position respectively. Of course, in still some other embodiments, the tabletop 3 can be located on the left and front sides of the base 1 at the first position and the second position respectively.

[0073] The support assembly 2 is rotatably connected to the base 1, so that the tabletop 3 can be switched between the first position and the second position, thereby converting the position of the tabletop 3 according to the position of the user. For example, when the user is located on the left side of the base 1, the tabletop 3 can be rotated to the left side of the base 1 through the support assembly 2. Correspondingly, when the user is located on the right side of the base 1, the tabletop 3 can be rotated to the right side of the base 1 through the support assembly 2. In this way, the position of the tabletop 3 can be adjusted according to the actual position of the user, which is convenient for the user to use the tabletop 3; since the tabletop 3 can rotate with the support assembly 2 to adjust its position, a single tabletop 3 can meet the usage requirements of the user in different positions. Therefore, the folding tabletop can be provided with only one tabletop 3, which can reduce the volume of the folding tabletop, further reduce the space occupied by the folding tabletop, relieve the congestion of the environmental space, and make the environmental space more spacious.

[0074] In some embodiments, the folding tabletop can be applied to the rear row seats of an automobile, and the folding tabletop is arranged in the middle of the rear row seats. In this way, when the user sits on the left seat, the tabletop mechanism can be set in the unfolded state and located at the first position (refer to Figure 1 ), when the user sits on the right seat, the tabletop mechanism in the first position can be rotated 180° around the first axis S1 so that it is located at the second position (refer to Figure 2 ).

[0075] The folding tabletop further includes a first driving mechanism 4 installed on the base 1. The first driving mechanism 4 is drivingly connected to the support assembly 2 to drive the support assembly 2 to rotate relative to the base 1, thereby driving the tabletop 3 to rotate to the first position or the second position. The first driving mechanism 4 can drive the tabletop 3 to rotate by driving the support assembly 2 to rotate, so that the tabletop 3 can automatically switch positions between the first position and the second position. In this way, it is not necessary to manually operate the folding tabletop to adjust the position of the tabletop 3, which reduces the usage difficulty of the folding tabletop and improves the usage convenience of the folding tabletop.

[0076] In this embodiment, the driving force of the first driving mechanism 4 acts on the support assembly 2. The support assembly 2 rotates under the driving force, thereby driving the tabletop 3 to rotate. That is to say, the driving force of the first driving mechanism 4 does not directly act on the tabletop 3. Thus, the position of the first driving mechanism 4 can be set away from the tabletop 3, so that the extra space occupied by the first driving mechanism 4 when the tabletop 3 is unfolded can be reduced. For example, when the folding tabletop is applied to a seat, the first driving mechanism 4 can always be housed in the main body of the seat. When the tabletop 3 is in the unfolded state or the folded state, the position of the first driving mechanism 4 will not change, and the first driving mechanism 4 will not be exposed to the external environment due to the unfolding of the tabletop 3. Thus, the occupancy of the first driving mechanism 4 on the environmental space can be reduced.

[0077] It should be noted that when the tabletop 3 is unfolded, it includes the process of the tabletop 3 being unfolded and also the period when the tabletop 3 remains in the unfolded state. Among them, Figure 1 the tabletop 3 of the shown folding tabletop is in the unfolded state.

[0078] In some embodiments, the tabletop 3 is driven by electricity to switch between the unfolded state and the folded state, which can further facilitate the user to use the folding tabletop.

[0079] In some embodiments, the first driving mechanism 4 includes a first driving member 41 and a first transmission assembly connected to the first driving member 41. One of the first driving member 41 and the first transmission assembly is connected to the base 1, and the other is connected to the support assembly 2. By providing the connected first driving member 41 and first transmission assembly, the first driving member 41 can be connected to the base 1 or the support assembly 2 through the first transmission assembly. Thus, the first transmission assembly can adjust the power direction of the first driving member 41, which is convenient for installing the first driving member 41 and helps save the space of the folding tabletop, thereby reducing the volume of the folding tabletop; the first transmission assembly can adjust the rotation speed of the support assembly 2. Thus, the rotation speed of the support assembly 2 can be controlled within a suitable range to improve the smoothness of the rotation of the support assembly 2; in addition, the first transmission assembly can also change the driving force direction, which is convenient for designing the installation position of the first driving member 41 and helps save the space of the folding tabletop.

[0080] In some embodiments, the first driving member 41 can be a motor.

[0081] Refer to Figure 5, in some embodiments, the first transmission assembly includes a worm gear 423 and a worm (not shown in the figure) meshing with the worm gear 423. The worm is connected to the output shaft of the first driving member 41, and the worm gear 423 is connected to the support assembly 2. The combination of the worm gear 423 and the worm can have a large transmission ratio, and its structure is compact, which can reduce the size of the first transmission assembly; the meshing tooth surfaces between the worm gear 423 and the worm are line contacts, and its load-bearing capacity is large, which helps to improve the stability of the first transmission assembly; the worm drive is equivalent to a screw drive, and the worm and the worm gear 423 are in multi-tooth meshing transmission, so the transmission between the two is stable and the noise is very small; there is a self-locking property between the worm gear 423 and the worm. When the lead angle of the worm is less than the equivalent friction angle between the meshing gear teeth, only the worm can drive the worm gear 423, and the worm gear 423 cannot drive the worm, so that the first driving member 41 can be protected safely. In this embodiment, the first driving member 41 can be arranged on the base 1.

[0082] Referring to Figure 7 , in other embodiments, the first transmission assembly includes a first gear 421 and an internal gear 422. The first gear 421 meshes with the teeth arranged on the inner circumferential side surface of the internal gear 422. The first gear 421 is connected to the output shaft of the first driving member 41, and the internal gear 422 is connected to the base 1; the first transmission assembly provided with the internal gear 422 and the first gear 421 has a high reduction ratio and low vibration, which can make the tabletop mechanism rotate smoothly.

[0083] In still other embodiments, the first transmission assembly includes a second gear (not shown in the figure) and a third gear (not shown in the figure). The second gear meshes with the teeth arranged on the outer circumferential side surface of the third gear. The second gear is connected to the output shaft of the first driving member 41, and the third gear is connected to the support assembly 2. In this embodiment, the first driving member 41 can be arranged on the base 1 or on the support assembly 2. The connection manner of the third gear and the support assembly 2 can refer to the above embodiments; the second gear and the third gear can be spur gears or bevel gears.

[0084] , in some embodiments, the support assembly 2 includes a rotating part 21 rotatably mounted on the base 1 and a support part 22 arranged on the rotating part 21. The tabletop 3 is arranged on the support part 22. The rotating part 21 can rotate relative to the base 1, so as to drive the support part 22 to rotate to switch the tabletop 3 between the first position and the second position. Referring to Figure 1 , the tabletop 3 is in the unfolded state and at the first position. Referring to Figure 2The table top 3 is in the unfolded state and in the second position. The table top 3 can rotate 180° around the first axis S1 from the first position to the second position. The support portion 22 is provided on the rotating portion 21. The rotating portion 21 can be regarded as an extension structure of the support portion 22. In this way, the connection between the support assembly 2 and the base 1 can be facilitated, which is conducive to improving the connection stability between the support assembly 2 and the base 1, so that the stability of the table top 3 during use can be improved.

[0085] Exemplarily, the base 1 may be provided with a first plate 11 , and the rotating portion 21 may also be in a plate shape, and the rotating portion 21 may be rotatably mounted on the first plate 11 .

[0086] Exemplarily, the first driving mechanism 4 may be connected to the rotating portion 21 and the first plate 11 respectively.

[0087] Reference Figure 6 In some embodiments, the first transmission assembly includes a worm gear 423 and a worm (not shown in the figure) meshing with the worm gear 423. The worm gear 423 is arranged on a side of the first plate 11 away from the rotating part 21. A first avoidance hole 114 can be opened in the center of the first plate 11, and a first connecting member 16 is used to penetrate the first avoidance hole 114 to connect the worm gear 423 to the rotating part 21.

[0088] Reference Figure 7 In some embodiments, the first transmission assembly includes a first gear 421 and an internal gear 422 meshing with the first gear 421. The first driving member 41 can be arranged on the supporting assembly 2; the connecting shaft 14 can be used to rotatably connect the center of the rotating part 21 and the center of the first plate 11. The internal gear 422 and the first gear 421 can be arranged on the side of the first plate 11 facing the rotating part 21. The internal gear 422 and the first gear 421 shown in the figure are arranged on the side of the first plate 11 away from the rotating part 21. At this time, a second avoidance hole can be provided on the first plate 11, and a second connecting member can be used to penetrate the second avoidance hole to connect the first gear 421 to the rotating part 21.

[0089] Reference Figure 1 The table top 3 includes two rotatably connected plates 31 and an arm 32 connecting the two plates 31 to the support portion 22. When the table top 3 is in the unfolded state, the two plates 31 can be as follows Figure 1 As shown in the unfolded state, the arm 32 and the support portion 22 can be vertically arranged. When the folding table board needs to be folded and stored, the board 31 can be rotated around the second axis S2 shown in the figure, so that the two boards 31 overlap to form Figure 4 In the state shown in (a), the two superimposed plates 31 can rotate around the third axis S3 shown in the figure to form Figure 4 In the state shown in (b), the arm body 32 can be turned upward around the fourth axis S4 shown in the figure to form Figure 4In the state shown in (c), at this time, the table top 3 is in a folded state, and the support portion 22 can rotate around the fifth axis S5 shown in the figure to form Figure 4 The state shown in (d) in which Figure 4 (d) in FIG. 1 does not show the table top 3.

[0090] It should be noted that Figure 4 The rotation of the plate body 31, the arm body 32 and the support portion 22 shown can be performed sequentially or simultaneously.

[0091] Reference Figure 5 and Figure 7 The base 1 is provided with a first limiting portion 151 and a second limiting portion 152, and the rotating portion 21 is provided with a third limiting portion 214. When the table top 3 is in the first position, the third limiting portion 214 abuts against the first limiting portion 151, and when the table top 3 is in the second position, the third limiting portion 214 abuts against the second limiting portion 152. The first limiting portion 151 and the second limiting portion 152 on the base 1 are used in conjunction with the third limiting portion 214 on the rotating portion 21 to limit the rotation angle of the rotating portion 21 in a manner of surface contact to form a rotation obstacle, thereby reducing the possibility of the table top 3 being offset due to an excessive rotation angle of the rotating portion 21. In this way, the distance between the table top 3 and the user can be guaranteed, and the comfort level when using the table top 3 can be guaranteed.

[0092] Exemplarily, the first limiting portion 151 and the second limiting portion 152 may be disposed on the first plate 11 of the base 1 .

[0093] Continue to refer to Figure 5 and Figure 7 In some embodiments, the base 1 is provided with a limiting groove 15, which is arranged around the rotation axis of the rotating part 21, and the third limiting part 214 is slidably arranged in the limiting groove 15, and the inner side walls at both ends of the limiting groove 15 along the length direction respectively form a first limiting part 151 and a second limiting part 152. The third limiting part 214 can be inserted into the limiting groove 15 to complete the sliding connection between the third limiting part 214 and the limiting groove 15, which can reduce the difficulty of assembling the rotating part 21 and the base 1, and help improve the assembly efficiency of the folding table top.

[0094] Exemplarily, the limiting groove 15 may be provided on the first plate 11 of the base 1. It should be noted that the bottom of the limiting groove 15 may penetrate the side of the first plate 11 away from the rotating portion 21, or may not penetrate the side of the first plate 11 away from the rotating portion 21. Figure 5 and Figure 7 The limiting groove 15 shown runs through a side surface of the first plate 11 facing away from the rotating portion 21 .

[0095] Exemplarily, the rotation angle of the tabletop 3 is 180°, so the central angle corresponding to the arc-shaped limiting groove 15 can be set to 180°.

[0096] Referring to Figure 7 , the third limiting portion 214 can also be used as the second connecting member connecting the first gear 421 and the rotating portion 21 in the above embodiment, and the limiting groove 15 can also be used as the second avoiding hole for avoiding the second connecting member in the above embodiment. At this time, the bottom of the limiting groove 15 penetrates through the side surface of the first plate 11 facing away from the rotating portion 21.

[0097] Referring to Figure 3 , Figure 8 and Figure 9 , the base 1 is provided with a first locking portion 112 and a second locking portion 113, and the rotating portion 21 is provided with a third locking portion 212. When the tabletop 3 is in the first position, the first locking portion 112 can be connected to the third locking portion 212 to limit the rotation of the rotating portion 21. When the tabletop 3 is in the second position, the second locking portion 113 can be connected to the third locking portion 212 to limit the rotation of the rotating portion 21. It can be understood that during the use of the folding tabletop, it may be pushed by an external force, and the rotating portion 21 is prone to relative movement with the base 1, resulting in the tabletop 3 being prone to rotation and position deviation, that is, the tabletop 3 is prone to position deviation; the first locking portion 112 is provided on the base 1, and the third locking portion 212 is provided on the rotating portion 21. When the tabletop 3 is in the first position, the first locking portion 112 can be connected to the third locking portion 212, thereby limiting the relative rotation between the rotating portion 21 and the base 1, so that the tabletop 3 can be kept in the first position; correspondingly, the cooperation between the second locking portion 113 on the base 1 and the third locking portion 212 on the rotating portion 21 can make the tabletop 3 be kept in the second position. In this way, the use stability of the folding tabletop can be improved, and the possibility of the tabletop 3 rotating due to external force collision during use can be reduced.

[0098] Exemplarily, the first locking portion 112 and the second locking portion 113 can be provided on the first plate 11.

[0099] Referring to Figure 8 and Figure 9In some embodiments, the first locking portion 112 and the second locking portion 113 are lock holes provided on the base 1, and the third locking portion 212 is a lock pin slidably provided on the rotating portion 21. When the lock pin is in a locked state, the lock pin is inserted into the lock hole, and when the lock pin is in an unlocked state, the lock pin is separated from the lock hole. By setting the first locking portion 112 and the second locking portion 113 as lock holes and the third locking portion 212 as a lock pin, the structures of the three can be simplified, thereby reducing the difficulty of processing the rotating portion 21 and the base 1; in addition, by moving the lock pin and locking the rotating portion 21 and the base 1 in a plug-in manner, the locking and unlocking between the rotating portion 21 and the base 1 can be conveniently controlled.

[0100] Exemplarily, the first locking portion 112 and the second locking portion 113 may be locking holes disposed on the first plate 11 .

[0101] In other embodiments, the first locking part 112 and the second locking part 113 can be set as magnets, and the third locking part 212 can be set as an electromagnet, or the first locking part 112 and the second locking part 113 can be set as electromagnets, and the third locking part 212 can be set as a magnet, or the first locking part 112, the second locking part 113 and the third locking part 212 can be set as an electromagnet together; in this case, the first locking part 112 and the second locking part 113 are locked with the third locking part 212 by magnetic attraction, and when unlocking is required, the electromagnet can be powered off.

[0102] Reference Figure 3 , Figures 9 to 11 The locking pin includes a connecting portion 2121 connected to the supporting assembly 2 and a locking portion 2122 for inserting into the locking hole. The connecting portion 2121 is arranged on the side of the rotating portion 21 away from the base 1. The rotating portion 21 is provided with a through hole 215. The locking portion 2122 can pass through the through hole 215 and be inserted into the locking hole. The connecting portion 2121 is arranged on the side of the rotating portion 21 away from the base 1. The connecting portion 2121 does not occupy the space between the rotating portion 21 and the base 1. In this way, the distance between the rotating portion 21 and the base 1 can be reduced, so that the base 1 can stably support the rotating portion 21, that is, the supporting stability of the rotating portion 21 by the base 1 is improved; the through hole 215 is arranged on the rotating portion 21. When the locking portion 2122 is inserted into the through hole 215 and the locking hole at the same time, the rotating portion 21 can be locked with the base 1. At this time, the rotating portion 21 cannot rotate relative to the base 1, so that the table top 3 can be kept in the first position or the second position.

[0103] Exemplarily, the connection portion 2121 may be disposed on a side of the rotating portion 21 facing away from the first plate 11 .

[0104] In some embodiments, the tabletop mechanism further includes a second driving mechanism 5 for driving the tabletop 3 to switch between a folded state and an unfolded state. The second driving mechanism 5 is respectively connected to the tabletop 3 and the third locking portion. When the second driving mechanism 5 drives the tabletop 3 to switch from the folded state to the unfolded state, it synchronously drives the third locking portion 212 to move so that the third locking portion 212 is connected to the first locking portion 112 / the second locking portion 113. The second driving mechanism 5 is provided to synchronously drive the locking portion 2122 to insert into the lock hole when driving the tabletop 3 to switch from the folded state to the unfolded state. During the process of the arm body 32 rotating and unfolding, the third locking portion 212 can move synchronously, so that the linkage between the two can be realized, ensuring that the locking pin can maintain the locking of the rotating portion 21 during the process of the tabletop mechanism being unfolded and used; in addition, the power for the tabletop 3 to switch between the folded state and the unfolded state and the power for the third locking portion 212 to move both come from the second driving mechanism 5, and there is no need to additionally provide a driving mechanism to drive the third locking portion 212 to move. In this way, the number of driving mechanisms inside the folding tabletop can be saved, which is beneficial to saving the space of the folding tabletop, reducing the volume of the folding tabletop, and thus reducing the occupation of the vehicle interior space.

[0105] In some embodiments, the second driving mechanism 5 can drive the arm body 32 to rotate around the fourth axis S4, thereby adjusting the angle between the arm body 32 and the support portion 22, and driving the two plate bodies 31 to rotate, so that the tabletop 3 can switch between the folded state and the unfolded state.

[0106] In some embodiments, the third locking portion 212 is a locking pin. The locking pin includes a connecting portion 2121 connected to the support assembly 2 and a locking portion 2122 for inserting into the lock hole. When the locking pin is in the unlocked state, the connecting portion 2121 and the locking portion 2122 are spaced apart. When the locking pin switches from the unlocked state to the locked state, the connecting portion 2121 moves towards the locking portion 2122 and pushes the locking portion 2122 to insert into the lock hole. It can be understood that during the use of the folding tabletop, it may be collided or pushed by an external force, and the direction of this external force is usually deviated from the first axis S1 (i.e., the rotation axis of the rotating portion 21). Thus, this external force has the effect of torsion, which easily causes the support portion 22 to twist. As the locking pin for locking the rotating portion 21 and the base 1, it is most likely to break when subjected to torsion; setting the spaced connecting portion 2121 and locking portion 2122, that is, setting the connecting portion 2121 and the locking portion 2122 as independent components. Since the connecting portion 2121 is connected to the support portion 22, the connecting portion 2121 will also be subjected to the external force of collision or push during the use of the folding tabletop. However, there is an abutting relationship between the connecting portion 2121 and the locking portion 2122. Even if the support portion 22 twists, a dislocation can occur between the connecting portion 2121 and the locking portion 2122. In this way, the torsion transmitted to the locking portion 2122 can be reduced, and the possibility of the locking portion 2122 breaking can be lowered, improving the reliability of the locking pin.

[0107] Exemplarily, the connecting portion 2121 can be driven by the second driving mechanism 5 to move towards the locking portion 2122, so that the connecting portion 2121 abuts against the locking portion 2122 and pushes the locking portion 2122 into the lock hole.

[0108] In this embodiment, the locking portion 2122 of the lock pin can be connected to the rotating portion 21, and the connecting portion 2121 of the lock pin can be connected to the supporting portion 22.

[0109] Of course, in other embodiments, the connecting portion 2121 and the locking portion 2122 can be fixedly connected, that is, the connecting portion 2121 and the locking portion 2122 are connected as a whole. At this time, other methods can be used to eliminate the influence of torque on the locking portion 2122. For example, a spring can be provided between the connecting portion 2121 and the second driving mechanism 5, so that relative displacement can occur between the connecting portion 2121 and the second driving mechanism 5.

[0110] In some embodiments, a positioning member 2123 is provided on one of the connecting portion 2121 and the locking portion 2122, and a positioning hole 2124 is provided on the other of the connecting portion 2121 and the locking portion 2122. When the connecting portion 2121 abuts against the locking portion 2122, the positioning member 2123 is inserted into the positioning hole 2124. In this embodiment, referring to Figure 10 , the positioning member 2123 is provided on the connecting portion 2121, and the positioning hole 2124 is provided on the locking portion 2122. Of course, in other embodiments, the positioning member 2123 can be provided on the locking portion 2122, and the positioning hole 2124 can be provided on the connecting portion 2121. By providing the positioning member 2123 and the positioning hole 2124 between the connecting portion 2121 and the locking portion 2122, in this way, the connection stability between the two can be improved by means of plug-in connection; in this embodiment, the positioning hole 2124 is a blind hole, that is to say, the positioning hole 2124 does not penetrate through the locking portion 2122, so as to reduce the influence on the strength of the locking portion 2122.

[0111] In some embodiments, the end dimension of the positioning member 2123 can be smaller than the root dimension of the positioning member 2123 (that is, when the connecting portion 2121 and the locking portion 2122 are separated, the dimension of the end of the positioning member 2123 close to the positioning hole 2124 is smaller than the dimension of the end of the positioning member 2123 far from the positioning hole 2124), and the opening of the positioning hole 2124 is arranged in a flared shape, so that it is convenient for the positioning member 2123 to be inserted into the positioning hole 2124.

[0112] Referring to Figure 9, the support assembly 2 is further provided with an elastic member 23, and the elastic member 23 is connected to the locking portion 2122 to drive the locking portion 2122 to separate from the lock hole. When the tabletop 3 is switched from the unfolded state to the folded state, the locking portion 2122 can move toward the side away from the lock hole under the elastic force of the elastic member 23 to separate from the lock hole to achieve reset, releasing the locking of the rotating portion 21 and the base 1, so that the rotating portion 21 can rotate relative to the base 1 to adjust the position of the tabletop 3. In some embodiments, the elastic member 23 can be a spring, a rubber pad, etc.

[0113] Exemplarily, the connecting portion 2121 is driven by the second driving mechanism 5. When the second driving mechanism 5 drives the connecting portion 2121 to move away from the locking portion 2122, the locking portion 2122 can separate from the lock hole under the elastic force of the elastic member 23 to achieve reset, releasing the locking of the rotating portion 21 and the base 1, so that the rotating portion 21 can rotate relative to the base 1 to adjust the position of the tabletop mechanism.

[0114] Referring to Figure 9 and Figure 11 , the support assembly 2 is provided with a guiding portion 221, and the guiding portion 221 is connected to the lock pin and is used to guide the movement of the lock pin. The guiding portion 221 can guide the moving direction of the lock pin, so that the lock pin can move along the direction parallel to the first axis S1 shown in Figure 1 , ensuring that the lock pin can be inserted into the lock hole to lock the rotating portion 21 and the base 1.

[0115] In some embodiments, the guiding portion 221 is a second groove 2211 provided on the rotating portion 21. Referring to Figure 9 and Figure 11 , an installation post 213 is provided on the side surface of the rotating portion 21 facing away from the first plate 11. The second groove 2211 is a groove structure recessed from the end surface of the installation post 213. The locking portion 2122 of the lock pin is slidably connected to the second groove 2211. At this time, the second groove 2211 is used to guide the movement of the locking portion 2122; the elastic member 23 can be arranged in the second groove 2211. Exemplarily, one end of the elastic member 23 can be connected to the locking portion 2122, and the other end of the elastic member 23 is connected to the side wall of the second groove 2211. Exemplarily, the locking portion 2122 can be L-shaped, so that it is convenient for the locking portion 2122 to be connected to the second groove 2211.

[0116] Two second grooves 2211 can be provided. Correspondingly, two elastic members 23 can be provided correspondingly. The positioning holes 2124 on the locking portion 2122 can be located between the two second grooves 2211, so as to balance the force on the locking portion 2122 and reduce the jamming phenomenon of the movement of the locking portion 2122.

[0117] In some other embodiments, the guiding portion 221 is a second sliding rail 2212 provided on the supporting portion 22. Refer to Figure 12 , the connecting portion 2121 of the locking pin is slidably connected to the second sliding rail 2212. At this time, the second sliding rail 2212 is used to guide the movement of the connecting portion 2121. Of course, the folding tabletop can be provided with the second groove 2211 and the second sliding rail 2212 at the same time.

[0118] The supporting portion 22 includes a housing 224 connected to the rotating portion 21, and a part of the third locking portion 212 is located in the enclosed area of the housing 224 and the rotating portion 21. By arranging a part of the third locking portion 212 within the enclosed area of the housing 224 and the rotating portion 21, the housing 224 can protect the third locking portion 212, reducing the occurrence of accidental unlocking caused by an external collision with the third locking portion 212 in the locked state, resulting in the separation of the third locking portion 212 from the first locking portion 112 / the second locking portion 113.

[0119] Exemplarily, when the third locking portion 212 is a locking pin, a part of the locking pin can be arranged within the enclosed area of the housing 224 and the rotating portion 21. For example, the connecting portion 2121 of the locking pin and a part of the locking portion 2122 can be arranged within the enclosed area of the housing 224 and the rotating portion 21.

[0120] Exemplarily, the guiding portion 221 can also be arranged within the housing 224. Exemplarily, when the guiding portion 221 is the second sliding rail 2212, the second sliding rail 2212 can be integrally formed with the housing 224, or can be two separate components, and the two can be assembled by bonding or using fasteners.

[0121] Refer to Figure 3 , Figure 9 and Figure 12 , the housing 224 includes a housing cover 2241 and a plurality of housing plates 2242. Among them, the housing plates 2242 are fixed to the rotating portion 21, the housing cover 2241 surrounds the circumference of the supporting portion 22, and the housing cover 2241 is rotatably connected to the housing plates 2242, so that the supporting portion 22 can rotate around the fifth axis S5.

[0122] In some embodiments, the second driving mechanism 5 includes a second driving member 51 and a second transmission assembly. The second transmission assembly includes a screw rod 521 connected to the output shaft of the second driving member 51 and a moving block 522 slidably disposed on the support assembly 2. The moving block 522 is threadedly connected to the screw rod 521, and the third locking portion 212 is connected to the moving block 522. The cooperation between the screw rod 521 and the moving block 522 of the second transmission assembly can convert the rotational power provided by the second driving member 51 into the power for the linear movement of the third locking portion 212. When the second driving member 51 is started, the screw rod 521 rotates following the output shaft of the second driving member 51, and the moving block 522 is connected to the third locking portion 212, thereby driving the third locking portion 212 to move linearly. In some embodiments, the second driving member 51 can be a motor, an engine, etc., and its power output shaft can perform a rotational movement. The second transmission assembly can convert the rotational movement into a linear movement.

[0123] Exemplarily, the third locking portion 212 is a locking pin, and the moving block 522 can be connected to the connecting portion of the locking pin. When the second driving member 51 is started, the screw rod 521 rotates following the output shaft of the second driving member 51, and the moving block 522 is connected to the connecting portion 2121, and the connecting portion 2121 is slidably connected to the housing cover 2241. Thus, the rotational movement of the screw rod 521 can be converted into the linear movement of the moving block 522, thereby driving the connecting portion 2121 to move up and down, and realizing driving the locking pin to insert into the locking hole to lock the rotating portion 21 and the first plate 11.

[0124] Of course, in some other embodiments, a gear-rack structure can be used to convert the rotational movement of the output shaft of the second driving member 51 into a linear movement. For example, the gear in the gear-rack structure can be connected to the output shaft of the second driving member 51, and the rack in the gear-rack structure can be connected to the connecting portion 2121.

[0125] Exemplarily, in this embodiment, the second driving mechanism 5 can also drive the arm body 32 to rotate about the fifth axis S5. The second driving mechanism 5 further includes a third driving member 53 and a third transmission assembly. The third driving member 53 and the third transmission assembly can be mounted on the housing plate 2242. The third driving member 53 can be a motor. The third transmission assembly includes a fourth gear (not shown in the figure) and a sector gear 54. Among them, the fourth gear is connected to the output shaft of the third driving member 53, and the sector gear 54 is connected to the housing cover 2241. The power of the third driving member 53 is transmitted to the housing cover 2241 through the fourth gear and the sector gear 54, thereby driving the housing cover 2241 to drive the support portion 22 as a whole to rotate about the fifth axis S5.

[0126] Continue to refer to Figure 1 and Figure 13, the moving block 522 is connected to the arm body 32 through a push plate 223. The two ends of the push plate 223 are respectively hinged to the push plate 223 and the arm body 32, and the arm body 32 is hinged to the housing 2241 of the support portion 22. Therefore, during the linear movement of the moving block 522, the position of the push plate 223 also changes, thereby driving the arm body 32 to rotate, realizing the unfolding and folding of the table board 3.

[0127] It should be noted that multiple driving members and transmission components can also be provided in the second driving mechanism 5 to drive the plate body 31 of the table board 3 to rotate around the second axis S2 and drive the table board 3 to rotate around the third axis S3.

[0128] Refer to Figure 6 , one of the base 1 and the rotating portion 21 is provided with a first slide rail 111, and the other of the base 1 and the rotating portion 21 is provided with a slider 211. The first slide rail 111 is arranged around the rotation axis of the rotating portion 21, and the rotating portion 21 is slidably engaged with the first slide rail 111 through the slider 211 to rotate relative to the base 1. Figure 6 As shown, the first slide rail 111 is arranged on the base 1 and the slider 211 is arranged on the rotating portion 21. Of course, in other embodiments, the slider 211 can also be arranged on the base 1 and the first slide rail 111 can be arranged on the rotating portion 21; the first slide rail 111 and the slider 211 which are slidably connected are respectively arranged on the base 1 and the rotating portion 21. The cooperation of the first slide rail 111 and the slider 211 can guide the relative movement between the rotating portion 21 and the base 1, reducing the possibility of the rotation direction of the rotating portion 21 deviating, so as to improve the stability of the folding table board.

[0129] Exemplarily, the first slide rail 111 can be arranged on the first plate 11 of the base 1.

[0130] In some embodiments, the slider 211 is annular; in this way, the first slide rail 111 can be in contact with the slider 211 everywhere, so as to improve the rotation stability of the rotating portion 21, and further improve the stability of the folding table board.

[0131] In other embodiments, a plurality of sliders 211 are provided, and the plurality of sliders 211 are arranged at intervals around the rotation axis of the rotating portion 21; in this way, the friction force generated between the first slide rail 111 and the slider 211 can be balanced by increasing the number of sliders 211, which can also improve the rotation stability of the rotating portion 21, and further improve the stability of the folding table board.

[0132] Continue to refer to Figure 6, in some embodiments, the first slide rail 111 is disposed on the first plate 11. The first slide rail 111 is a first groove recessed from the surface of the first plate 11. The slider 211 is disposed on the rotating portion 21. The slider 211 is a protrusion protruding from the surface of the rotating portion 21. The protrusion is slidably disposed in the first groove. In other embodiments, the first slide rail 111 is disposed on the rotating portion 21. The first slide rail 111 is a first groove recessed from the surface of the rotating portion 21. The slider 211 is disposed on the first plate 11. The slider 211 is a protrusion protruding from the surface of the first plate 11. The protrusion is slidably disposed in the first groove. Setting the first slide rail 111 as a groove structure and the slider 211 as a protrusion structure can simplify the structures of the first slide rail 111 and the slider 211, thereby reducing the processing difficulty of the two. In addition, inserting the slider 211 into the first slide rail 111 can achieve the sliding assembly of the two, thereby reducing the assembly difficulty of the two and helping to improve the assembly efficiency of the folding table board.

[0133] In some embodiments, the thickness of the periphery of the first plate 11 can be locally increased to facilitate the formation of the first groove.

[0134] In some embodiments, the first slide rail 111 can be integrally formed with the first plate 11, that is, there is no splicing or assembly trace between the first slide rail 111 and the first plate 11, so as to improve the connection stability between the first slide rail 111 and the first plate 11. The slider 211 can be integrally formed with the rotating portion 21, that is, there is no splicing or assembly trace between the slider 211 and the rotating portion 21, so as to improve the connection stability between the slider 211 and the rotating portion 21.

[0135] Referring to Figures 6 to 9 , the base 1 is provided with an annular enclosure wall 12, and the annular enclosure wall 12 surrounds the edge of the rotating portion 21. When the base 1 is provided with the annular enclosure wall 12 and the rotating portion 21 is disposed in the enclosed area of the annular enclosure wall 12, the annular enclosure wall 12 can play a role in protecting the rotating portion 21 and reduce the probability that other components in the environment come into contact with the rotating portion 21 and cause wear.

[0136] Exemplarily, the annular enclosure wall 12 can be disposed on the first plate 11 of the base 1.

[0137] The inner side wall of the annular surrounding wall 12 is provided with a fourth limiting portion 121, which is used to abut against the side of the rotating portion 21 away from the base 1. In this way, the fourth limiting portion 121 can limit the relative distance between the rotating portion 21 and the base 1, and in the direction parallel to the first axis S1, the fourth limiting portion 121 can provide a limit for the rotating portion 21, limiting the movement of the rotating portion 21 toward the side away from the base 1, so that the risk of the rotating portion 21 detaching from the base 1 can be reduced. In addition, if the rotating portion 21 bounces during the rotation process, the fourth limiting portion 121 can abut against the rotating portion 21, so that it can rotate smoothly, thereby improving the stability of the rotation of the tabletop mechanism.

[0138] In some embodiments, a second plate 13 may be provided on a side of the first plate 11 away from the rotating portion 21 , and the second plate 13 may be fixed to an external device by fasteners such as screws, thereby achieving installation of the folding table top and the external device.
