Therefore, the "in some embodiments" appearing throughout the specification does not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner.

[0048] The following describes in detail a movable table top and a vehicle provided by the present application by listing specific embodiments.

[0049] Figure 1 is a schematic diagram of a movable table top in a storage state in an embodiment of the present application, Figure 2 is a schematic diagram of a movable table top in a semi-expanded state in an embodiment of the present application, Figure 3 is a schematic diagram of a movable table top in a fully extended state in an embodiment of the present application, Figure 4 This is a structural exploded diagram of a movable table top in the embodiment of the present application, referring to Figures 1 to 4 The embodiment of the present application provides a movable table top, including a base plate 1, a table top body 2, a support member 3, and a first driving assembly 6; the support member 3 is rotatably connected to the base plate 1; the first driving assembly 6 includes a first driving member 61, an active member and a driven member, the first driving member 61 is fixedly connected to the support member 3, the active member is connected to the first driving member, the driven member is transmission-connected to the active member, and the table top body 2 is connected to the driven member; the first driving member 61 drives the active member to rotate, the active member drives the driven member to rotate synchronously, and the driven member drives the table top body 2 to move to adjust the posture of the table top body 2.

[0050] In this embodiment, the movable table top can be used not only in a car environment, but also in an office environment, a medical environment, a home environment, etc. The specific application scenario is not limited in this embodiment. To facilitate the understanding of this application, the embodiment of this application is explained as the movable table top being applicable to a car environment. In actual applications, the movable table top is usually arranged on the side of the seat, such as the movable table top is arranged between the main driver's seat or the co-driver's seat, which is convenient for the passengers on the main driver's seat and the co-driver's seat; or, the movable table top is arranged behind the main driver's seat or the co-driver's seat, which is convenient for the rear passengers.

[0051] The base plate 1 is used to realize the installation and fixation of the movable table top. The base plate 1 is arranged along the height direction of the vehicle. In the embodiment of the present application, the height direction of the vehicle is regarded as the first direction. Figures 1 to 3 As shown in the X direction, the substrate 1 is fixedly connected to the side or rear side of the seat, specifically, as Figures 1 to 3 As shown, a first connecting hole 11 is opened on the base plate 1, and the first connecting hole 11 is used for fasteners 13 such as bolts, screws, and rivets to pass through, so as to detachably connect the base plate 1 to the seat. This not only achieves the fixation of the base plate 1, but also facilitates the later disassembly of the base plate 1 for inspection and maintenance.

[0052] The table board body 2 is the main part of the movable table board. When the table board is not in use, the movable table board is in a storage state. Figure 1 As shown, the table board body 2 is hidden beside the seat, and the surface of the table board body 2 is in the first plane. Figures 1 to 3 The plane formed by the first direction X and the second direction Y in the table top body 2 can be parallel to the surface of the base plate 1; when the table top is used, the movable table top can be adjusted to a semi-expanded state first, and the semi-expanded state is as follows: Figure 2 As shown, the table board body 2 is taken out from the side of the seat and rotated to a state nearly coaxial with the base plate 1; then the movable table board is adjusted to be in a fully extended state, as shown in FIG. Figure 3 As shown, the board surface of the table board body 2 is in the second plane. Figures 1 to 3 In the plane formed by the second direction Y and the third direction Z, the board surface of the board body 2 can be perpendicular to the board surface of the substrate 1.

[0053] Among them, the "parallel" described in this embodiment includes not only the absolute parallel situation, but also the generally recognized approximately parallel situation, such as the state where the angle formed by the planes is -1° to 1°, which is also regarded as mutually parallel; at the same time, "vertical" also includes not only the absolute vertical situation, but also the generally recognized approximately vertical situation, such as the state where the angle formed by the planes is 89° to 91°, which is also regarded as mutually perpendicular.

[0054] The movement of the table top body 2 relative to the base plate 1 is realized by the support member 3 and the first driving assembly 6. The support member 3 is rotatably connected to the base plate 1 and can rotate relative to the base plate 1. Figure 1 and Figure 2 As shown, the support member 3 can rotate relative to the base plate 1 in the first plane. When the movable table top is in the storage state, the support member 3 and the base plate 1 are close to being perpendicular to each other (such as Figure 1 ), when the movable table top is in a semi-expanded or fully expanded state, the support member 3 and the base plate 1 are close to being parallel to each other (such as Figure 2 and Figure 3 ).

[0055] The first driving assembly 6 includes a first driving member 61, an active member and a driven member. The first driving member 61 is fixedly connected to the support member 3. The support member 3 rotates relative to the base plate 1, which drives the first driving member 61 to move synchronously. The active member is connected to the first driving member 61, the driven member is connected to the active member, and the table board body 2 is connected to the driven member. During the adjustment of the movable table board, the first driving member 61 drives the active member to rotate, the active member drives the driven member to rotate synchronously, and the driven member drives the table board body 2 to move, so that the posture of the table board body 2 can be adjusted. Figures 2 to 3 When the movable table top is adjusted from a semi-expanded state to a fully expanded state, the follower drives the table top body 2 to rotate in the second plane, and the table top body 2 can be adjusted from a vertical posture to a horizontal posture.

[0056] The movable table top of the present application includes a base plate 1, a table top body 2, a support member 3, and a first drive assembly 6. The support member 3 is rotatably connected to the base plate 1. The first drive assembly 6 includes a first drive member 61, an active member, and a driven member. The first drive member 61 is fixedly connected to the support member 3, the active member is connected to the first drive member, the driven member is transmission-connected to the active member, the table top body 2 is connected to the driven member, the first drive member 61 drives the active member to rotate, the active member drives the driven member to rotate synchronously, and the driven member drives the table top body 2 to move to adjust the posture of the table top body 2. Thus, the posture of the table top body 2 can be adjusted by rotating the first drive member 61, the active member, and the driven member. Compared with the prior art, the driving structure of the first drive assembly 6 is simpler, the overall space occupied is smaller, it is not easy to burden the volume of the movable table top, and it is more convenient for the movable table top to be installed and arranged inside the vehicle. At the same time, the use of the rotation of the components to achieve the drive is helpful to improve the sensitivity of the driving process and improve the driving accuracy.

[0057] Optionally, in some embodiments, the active member has a first tooth structure, the driven member has a second tooth structure, and the first tooth structure is meshed with the second tooth structure, so that transmission is achieved between the active member and the driven member through the meshing of the tooth structures. The tooth meshing has high transmission efficiency, high precision, and high reliability, and can achieve the transmission of larger loads, thereby helping to improve the driving efficiency and driving reliability of the first driving component 6, and improving the stability of the movement process of the table board body 2.

[0058] In other embodiments, the surface roughness of the active member and the driven member is relatively high, and the active member can drive the driven member to rotate synchronously through the friction between them. For example, the active member and the driven member are respectively wheels with relatively high surface roughness, and the two wheels are in contact with each other. During the rotation of the active member, the friction between them can drive the driven member to rotate synchronously. The friction transmission has a simple structural form, which is more convenient for the processing design of the active member and the driven member, and controls the processing cost of the first drive component 6.

[0059] Optionally, Figure 5 This is a structural explosion diagram of a first drive assembly in an embodiment of the present application. Please refer to Figure 5 In some embodiments, the active member is a transmission shaft 62, and the outer peripheral surface of the transmission shaft 62 is provided with a first tooth structure; the driven member is a transmission plate 64, one end of the transmission plate 64 is provided with a second tooth structure, and the other end of the transmission plate 64 is connected to the table board body 2.

[0060] In this embodiment, the outer peripheral surface of the transmission shaft 62 is provided with a first tooth-shaped structure, wherein the transmission shaft 62 can be directly processed at its end to form the first tooth-shaped structure by an integral molding method, such as Figure 5 As shown, the transmission shaft 62 can also be formed by assembling and connecting two parts, a shaft body 621 and a gear sleeve 622. One end of the shaft body 621 is connected to the first driving member 61, and the other end of the shaft body 621 is fixedly connected to the gear sleeve 622. The fixed connection method includes but is not limited to key connection, welding, etc. The outer peripheral surface of the gear sleeve 622 is provided with a first tooth-shaped structure. This embodiment does not limit the processing method of the first tooth-shaped structure.

[0061] In addition, the first driving member 61 can be a driving motor, which has a simple structure, is easy to install and arrange, has a fast response, and has high driving accuracy, which helps to improve the driving performance of the first driving assembly 6. The end of the transmission shaft 62 away from the driven member is rigidly connected to the output shaft of the driving motor, so that the first driving member 61 can drive the transmission shaft 62 to rotate through its output shaft. Among them, rigid connection refers to a connection method in which the mutually connected parts do not produce relative displacement during operation, and the relative position and direction of the connected parts remain unchanged.

[0062] The driven member is a transmission plate 64, which can be set as a strip-shaped structure to facilitate the connection between the transmission plate 64 and the transmission shaft 62 and the table board body 2. One end of the transmission plate 64 is processed with a second tooth-shaped structure, and the other end of the transmission plate 64 is connected to the table board body 2. Due to the limitation of the processing conditions on the transmission plate 64, the number of teeth of the second tooth-shaped structure processed on the transmission plate 64 is limited. The first tooth-shaped structure on the transmission shaft 62 is meshed with the second tooth-shaped structure on the transmission plate 64, which can achieve a rotation within a smaller angle range, such as a range of 30° to 90°. In this embodiment, the second tooth-shaped structure is directly processed on the transmission plate 64, which helps to simplify the structure of the first drive component 6 and reduce the difficulty of designing and processing the first drive component 6.

[0063] Optionally, Figure 6 This is a schematic diagram of a transmission plate in the embodiment of the present application, please refer to Figure 6 In some embodiments, the active member is a transmission shaft 62, and the outer peripheral surface of the transmission shaft 62 is provided with a first tooth structure; the driven member includes a transmission plate 64 and a gear 63, the gear 63 is fixedly connected to one end of the transmission plate 64, and the gear 63 is provided with a second tooth structure, and the other end of the transmission plate 64 is connected to the table board body 2.

[0064] In this embodiment, the outer peripheral surface of the transmission shaft 62 is provided with a first toothed structure, and its implementation is the same or similar to the above-mentioned embodiment, and this embodiment is not repeated here. The first driving member 61 can be a driving motor, and the end of the transmission shaft 62 away from the driven member is rigidly connected to the output shaft of the driving motor, so that the first driving member 61 can drive the transmission shaft 62 to rotate through its output shaft.

[0065] The driven member includes a transmission plate 64 and a gear 63, wherein the gear 63 is fixedly connected to one end of the transmission plate 64, wherein the gear 63 and the transmission plate 64 can be fixedly connected by welding, key connection, assembly connection, etc. After the fixed connection, the gear 63 and the transmission plate 64 cannot rotate relative to each other. A second tooth-shaped structure is provided on the gear 63, and the second tooth-shaped structure on the gear 63 is meshed with the first tooth-shaped structure on the transmission shaft 62, and the other end of the transmission plate 64 away from the gear 63 is connected to the table board body 2. Thus, the first driving member 61 drives the transmission shaft 62 to rotate, and the transmission shaft 62 drives the gear 63 and the transmission plate 64 to rotate synchronously through the meshing portion, and the other end of the transmission plate 64 drives the table board body 2 to rotate, thereby realizing the adjustment of the posture of the table board body 2.

[0066] Optionally, please continue to refer to Figure 6A groove 640 is provided at one end of the transmission plate 64, and at least a portion of the gear 63 is embedded in the groove 640. The groove 640 provides an avoidance space for the installation of the gear 63, which helps to save the space occupied by the driven part, thereby helping to save the space occupied by the first drive assembly 6, and making it easier to install and arrange the first drive assembly 6 on the support member 3.

[0067] Optionally, in some embodiments, the first tooth structure is distributed in a spiral shape on the outer peripheral surface of the transmission shaft 62, so that the transmission shaft 62 forms a worm and the gear 63 forms a turbine. The turbine and the worm have a compact structure, a large transmission ratio, and smooth transmission. At the same time, the transmission shaft 62 and the gear form a worm gear mechanism, which provides more sufficient space for the connection between the first drive member 61 and the transmission shaft 62, and is more convenient for the installation and layout of the first drive member 61.

[0068] In other embodiments, the axis of the transmission shaft 62 is parallel to the axial direction of the gear 63, so that the first tooth structure and the second tooth structure are horizontally meshed for transmission. In this manner, the meshing of the first tooth structure and the second tooth structure is simple, which helps to reduce the design difficulty of the first drive component 6.

[0069] Optionally, in some embodiments, the transmission plate 64 is slidably connected to the table board body 2, and the end of the table board body 2 close to the transmission plate 64 is also rotatably connected to the support member 3. Therefore, when the transmission shaft 62 drives the transmission plate 64 to rotate or the transmission shaft 62 drives the transmission plate 64 to rotate through the gear 63, the transmission plate 64 and the table board body 2 slide relative to each other, and the table board body 2 rotates around the part where it is rotatably connected to the support member 3, thereby adjusting the posture of the table board body 2. Figure 3 As shown, when the transmission plate 64 is slidably connected to the table board body 2 and the table board body 2 is rotatably connected to the support member 3, when the movable table board is in a fully unfolded state, a triangular structure is formed between the support member 3, the transmission plate 64 and the table board body 2. Figure 3 , a schematic diagram of a right-angle support structure formed between the support member 3, the transmission plate 64 and the table board body 2 is shown, wherein the support member 3 is equivalent to a right-angle side of the right-angle support structure, the transmission plate 64 is equivalent to a hypotenuse of the right-angle support structure, and the table board body 2 is equivalent to a right-angle side of the right-angle support structure. The above-mentioned triangular support structure can provide a stable support for the table board body 2, which helps to improve the stability of the table board body 2 when it is in a fully unfolded state.

[0070] In other embodiments, the transmission plate 64 may also be fixedly connected to the table top body 2. When the transmission shaft 62 drives the transmission plate 64 to rotate or the transmission shaft 62 drives the transmission plate 64 to rotate through the gear 63, the transmission plate 64 directly drives the table top body 2 to rotate. This driving structure is simpler, but it is easy to cause the table top body 2 to occupy a larger space during the rotation process, and it is impossible to effectively ensure the stability of the table top body 2 during the rotation process and the use process.

[0071] Optionally, Figure 7 This is a schematic diagram of a table top body in the embodiment of the present application. Please refer to Figure 7 The end of the table board body 2 near the transmission plate 64 is provided with a slide groove 21, which is provided on one side of the table board body 2 near the transmission plate 64 and passes through the end of the table board body 2. The shape and structure of the slide groove 21 are adapted to the shape and structure of the transmission plate 64. At least part of the transmission plate 64 is embedded in the slide groove 21 and is slidably connected with the slide groove 21. The slide groove 21 can improve the stability of the transmission plate 64 during movement, and is more helpful to improve the stability of the table board body 2 during rotation.

[0072] Specifically, refer to Figure 6 and Figure 7 , a rotating shaft 641 is provided at the end of the transmission plate 64 away from the support member 3, a slide rail 23 is provided on the groove wall 22 of the slide groove 21, and the rotating shaft 641 is rotatably arranged in the slide rail 23, so as to realize the sliding connection between the transmission plate 64 and the slide groove 21, and the transmission plate 64 can rotate relative to the table board body 2 during the sliding process. Among them, the slide rail 23 can be arranged on the groove wall 22 on one side of the slide groove 21, so that the transmission plate 64 slides on one side, and the slide rail 23 can also be arranged on the groove walls 22 on the opposite sides of the slide groove 21, so that the transmission plate 64 slides on both sides. In addition, in some embodiments, a sleeve 642 is provided on the outer sleeve of the rotating shaft 641, and the sleeve 642 directly contacts the slide groove 21. The sleeve 642 can play a certain protective role on the rotating shaft 641 to avoid damage to the surface of the rotating shaft 641, thereby improving the reliability of the rotation connection.

[0074] Optionally, a first rotating shaft 31 and a second rotating shaft 32 are provided on the support member 3; the first rotating shaft 31 is provided on a side close to the base plate 1, and the second rotating shaft 32 is provided on a side close to the table top body 2; the transmission plate 64 is rotationally connected to the first rotating shaft 31, and the end of the table top body 2 close to the transmission plate 64 is rotationally connected to the second rotating shaft 32.

[0075] In this embodiment, the first rotating shaft 31 and the second rotating shaft 32 can be an integral part formed by an integral molding process with the support member 3. The first rotating shaft 31 is located on the side close to the base plate 1, and the transmission plate 64 is provided with an axial hole for passing the first rotating shaft 31. The first rotating shaft 31 can be movably passed through the axial hole to realize the rotational connection between the support member 3 and the transmission plate 64. The second rotating shaft 32 is located on the side close to the table board body 2, and the table board body 2 is provided with an axial hole for passing the second rotating shaft 32. The second rotating shaft 32 can be movably passed through the axial hole to realize the rotational connection between the support member 3 and the table board body 2.

[0076] Alternatively, the first rotating shaft 31 and the second rotating shaft 32 may be a split structure with the support member 3, and the support member 3 is provided with shaft holes on one side close to the base plate 1 and the side close to the table board body 2, respectively. One end of the first rotating shaft 31 and the second rotating shaft 32 is immovably inserted into the shaft hole on the support member 3, and the other end is movably inserted into the transmission plate 64 and the table board body 2, thereby realizing the rotational connection between the support member 3 and the transmission plate 64 and the table board body 2. Of course, one end of the first rotating shaft 31 and the second rotating shaft 32 may also be movably inserted into the shaft hole on the support member 3, and the other end is immovably inserted into the transmission plate 64 and the table board body 2, thereby realizing the rotational connection between the support member 3 and the transmission plate 64 and the table board body 2.

[0077] Optionally, the support member 3 is provided with a mounting groove 33, and at least part of the transmission plate 64 is embedded in the mounting groove 33 and is rotatably connected to the first rotating shaft 31.

The first rotating shaft 31 and the second rotating shaft 32 are provided on at least one groove wall of the mounting groove 33, the transmission plate 64 is rotatably connected to the first rotating shaft 31, and the table board body 2 is rotatably connected to the second rotating shaft 32. The mounting groove 33 can limit the transmission plate 64 during the turning process of the transmission plate 64, so as to prevent the transmission plate 64 from falling out of the support member 3, thereby ensuring the reliability of the rotatable connection between the support member 3 and the transmission plate 64.

[0078] Optionally, both the first tooth profile structure and the second tooth profile structure are helical teeth, such as 30° helical teeth, 45° helical teeth, 60° helical teeth, etc. The helical teeth have good meshing properties and a large overlap, and the transmission is smoother and has less noise, which helps to improve the reliability of the meshing of the first tooth profile structure and the second tooth profile structure, thereby improving the load-bearing capacity of the transmission between the active member and the driven member.

The transmission ratio is the rotational speed ratio between the active member and the driven member, and can also be expressed as the ratio of the number of teeth of the second tooth structure to the number of teeth of the first tooth structure. The transmission ratio between the first tooth structure and the second tooth structure is greater than 1, which is manifested as the small gear driving the rotation of the large gear, and has a certain deceleration effect in the transmission process between the active member and the driven member, thereby helping to achieve smooth rotation of the table top body 2.

[0080] Optionally, please continue to refer to Figures 1 to 4 The movable table top further includes a second driving assembly 5, which is disposed on the base plate 1 and connected to the support member 3; the second driving assembly 5 is used to drive the support member 3 to rotate relative to the base plate 1. In this embodiment, the second driving assembly 5 is detachably connected to the base plate 1 and the second driving assembly 5 is detachably connected to the support member 3 by fastener assembly connection, so that the second driving assembly 5 can be disassembled for inspection and maintenance when a fault occurs in the second driving assembly 5.

[0081] Optionally, the movable table top also includes a mounting plate 7, which is fixedly connected to the base plate 1, and the second drive assembly 5 is mounted on the mounting plate 7. The mounting plate 7 and the base plate 1 can be fixedly connected by laser welding, fastener assembly connection, snap connection, etc. The size of the mounting plate 7 along the second direction Y is adapted to the size of the base plate 1 to avoid the mounting plate 7 from excessively occupying the space in the vehicle. The second drive assembly 5 is mounted on the mounting plate 7, and the mounting plate 7 can strengthen the local structural strength and rigidity of the base plate 1. The second drive assembly 5 is mounted on the mounting plate 7 to avoid local deformation or damage to the base plate 1, etc., and improve the durability of the base plate 1. At the same time, the mounting plate 7 can pre-position the installation of the second drive assembly 5, which is more convenient for the installation and fixation of the second drive assembly 5.

[0082] Optionally, the second driving component 5 includes a second driving member 51 and a connecting shaft 52; the second driving member 51 is fixedly connected to the mounting plate 7, one end of the connecting shaft 52 is connected to the second driving member 51, and the other end of the connecting shaft 52 passes through the support member 3 and is rotatably connected to the substrate 1; the second driving member 51 is used to drive the connecting shaft 52 to rotate, and the connecting shaft 52 drives the support member 3 to rotate synchronously.

[0083] In this embodiment, the second driving member 51 is fixed on the mounting plate 7. The second driving member 51 can be a driving motor. The driving motor has a simple structure, is easy to install and arrange, has a fast response, and has high driving accuracy, which helps to improve the driving performance of the second driving assembly 5. When the second driving member 51 is a driving motor, one end of the connecting shaft 52 is rigidly connected to the output shaft of the driving motor, so that the driving motor drives the connecting shaft 52 to rotate through its output shaft.

[0084] In some embodiments, the output shaft end of the second driving member 51 may be provided with a flattening structure on its outer circumferential surface, and the end of the connecting shaft 52 close to the second driving member 51 is provided with a plug-in hole, and the inner wall of the plug-in hole is also provided with a flattening structure, so that the connection between the output shaft of the second driving member 51 and the connecting shaft 52 is achieved through the cooperation of the flattening structure, and while ensuring the connection, it can play an effective circumferential limiting role on the output shaft of the second driving member 51 and the connecting shaft 52.

[0085] The other end of the connecting shaft 52 passes through the supporting member 3 and is rotatably connected to the base plate 1. Figure 4 , the support member 3 is provided with a through hole 34 for the connecting shaft 52 to pass through, and the base plate is provided with a second connecting hole 12 for the connecting shaft 52 to pass through. The connecting shaft 52 is inserted into the through hole 34 and the second connecting hole 12, wherein the connecting shaft 52 cannot rotate relative to the through hole 34, but can rotate relative to the second connecting hole 12, so that during the rotation of the connecting shaft 52, the support member 3 is driven to rotate relative to the base plate 1. In addition, the second connecting hole 12 can be a through hole or a blind hole, which is not limited in this embodiment. Furthermore, a sleeve 54 can be provided at the end of the connecting shaft 52 inserted into the second connecting hole 12, and the sleeve 54 can protect the outer peripheral surface of the connecting shaft 52 to prevent the connecting shaft 52 from fatigue failure when the connecting shaft 52 rotates in the second connecting hole 12 for a long time.

[0086] In the case where the movable table top also includes a mounting plate 7, the other end of the connecting shaft 52 simultaneously penetrates the mounting plate 7 and the support member 3 and is rotatably connected to the base plate 1. Specifically, the mounting plate 7 is also provided with a through hole for the connecting shaft 52 to pass through, and the connecting shaft 52 can rotate relative to the through hole on the mounting plate 7. In addition, there can be two shaft sleeves 54, and the connecting shaft 52 is passed through the through hole on the mounting plate 7 through the shaft sleeves 54, so as to avoid fatigue failure of the connecting shaft 52 caused by long-term rotation of the connecting shaft 52 in the through hole of the mounting plate 7.

[0087] Optionally, refer to Figure 4 The connecting shaft 52 has an outer peripheral surface arranged around its axial direction, and a key groove is formed on the outer peripheral surface. The through hole 34 of the support member 3 is also configured with a key groove, and a key 55 is arranged in the key groove. Figure 4 The key is a flat key, and the connecting shaft 52 and the support member 3 are connected by a key, so that the connecting shaft 52 and the support member 3 cannot rotate relative to each other. When the second driving member 51 drives the connecting shaft 52 to rotate, the connecting shaft 52 can drive the support member 3 to rotate synchronously.

[0088] Optionally, refer to Figure 4, the connecting shaft 52 is provided with a limiting section 521, which is penetrated in the first support arm 3; the radial dimension of the limiting section 521 is greater than the radial dimension of the two ends of the connecting shaft 52. The limiting section 521 and the connecting shaft 52 can be formed in an integral manner, and part of the outer peripheral surface of the connecting shaft 52 is convexed along the radial direction of the connecting shaft 52 to form the limiting section 521, wherein the convex refers to protruding in a direction away from the axis of the connecting shaft 52, so that the radial dimension of the limiting section 521 formed is greater than the radial dimension of other parts of the connecting shaft 52. The limiting section 521 is penetrated in the through hole 34 of the support member 3, and the end of the connecting shaft 52 is penetrated in the second connecting hole 12 of the substrate 1. Accordingly, the radial dimension of the through hole 34 is greater than the radial dimension of the second connecting hole 12, and the surface of the support member 3 abuts against the surface of the substrate 1, thereby playing an axial limiting role on the connecting shaft 52 through the change of size, improving the connection reliability of the connecting shaft 52 with the support member 3 and the substrate 1, and thus improving the stability of the second driving assembly 5.

[0089] Optionally, refer to Figures 1 to 4 The second driving assembly 5 further includes a stopper 53; the stopper 53 is fixedly connected to the base plate 1; the stopper 53 is used to limit the rotation range of the support member 3 relative to the base plate 1. The stopper 53 is arranged on the side of the support member 3 along the second direction Y and is fixedly connected to the base plate 1. The stopper 53 can be fixedly connected to the base plate 1 by laser welding, fastener assembly connection, adhesive connection, etc. Figure 4 , the limiting member 53 is fixedly connected to the substrate 1 by a plurality of screws 56, and the limiting member 53 and the substrate 1 are respectively provided with connection holes for the screws 56 to pass through, so as to facilitate the removal or replacement of the limiting member 53. In some embodiments, a plurality of connection holes for the screws 56 to pass through can also be provided on the substrate 1, so as to facilitate the adjustment of the connection position of the limiting member 53 on the substrate 1.

[0090] like Figures 1 to 3 As shown, the limiter 53 can limit the rotation of the support member 3 in the first plane. When the support member 3 rotates counterclockwise in the first plane until it abuts against the limiter 53, it can no longer rotate in this direction, thereby limiting the unfolded position of the support member 3 relative to the base plate 1, and playing a reasonable supporting role for the table board body 2. Of course, there can be two limiters 53, both of which are fixedly connected to the base plate 1, wherein one limiter 53 is used to limit the rotation of the support member 3 to a horizontal position, and the other limiter 53 is used to limit the rotation of the support member 3 to a vertical position. In addition, in the case where the movable table board also includes a mounting plate 7, the limiter 53 can also be fixedly connected to the mounting plate 7.

[0091] In the embodiment of the present application, during the unfolding process of the movable table top, the second driving assembly 5 first drives the support member 3 to rotate in the first plane to a position parallel to the base plate 1, and the support member 3 drives the table top body 2 to move to a position parallel to the base plate 1. The process is as follows: Figure 1 to Figure 2 Then the first driving assembly 6 drives the table board body 2 to rotate in the second plane to a position perpendicular to the support member 3. At this time, the table board body 2 and the base plate 1 are also in a mutually perpendicular position. The process is as shown in FIG. Figures 2 to 3 As shown. When the table top body 2 is in Figure 3 In the position shown, the table board body 2 can be used by passengers to place items and provide hand support for passengers. Similarly, during the storage of the movable table board, the first drive component 6 first drives the table board body 2 to rotate in the second plane to a position parallel to the support member 3, and then the second drive component 5 drives the support member 3 to rotate in the first plane to a position perpendicular to the base plate 1, and the support member 3 drives the table board body 2 to move to a position perpendicular to the base plate 1, thereby realizing the storage of the movable table board.

[0092] The movable table top of the present application abandons the manual operation mode of transmission, and adopts the coordinated use of the first drive component 6 and the second drive component 5 to realize the automatic expansion or storage of the table top, which greatly facilitates the use of the passengers. The table top will not cause hand pinching or accidental injury to the passengers during the expansion or storage process, which effectively improves the safety of the table top during use. At the same time, the first drive component 6 and the second drive component 5 have a simple structure and occupy a small space as a whole, which is not easy to burden the volume of the movable table top, and is more convenient for the installation and layout of the movable table top inside the vehicle. In addition, the first drive component 6 and the second drive component 5 can be driven by dual motors, which helps to improve the sensitivity of the driving process and improve the driving accuracy.

[0093] An embodiment of the present application also provides a vehicle, comprising the movable table top described in any of the aforementioned embodiments. The movable table top is used in conjunction with the first drive component 6 and the second drive component 5, and can be automatically unfolded or retracted, which greatly facilitates the use of the vehicle by the passengers. The table top will not cause pinching of the passengers' hands or accidental injuries during the unfolding or retracting process, which effectively improves the safety of the table top during use. At the same time, the movable table top occupies less space in the vehicle, which helps to improve the comfort of the vehicle and improve the passengers' satisfaction with the vehicle.
