Description

Technical Field

[0001] This utility model relates to the field of table technology, and more specifically, to a table assembly, a seat assembly, and a vehicle. Background Technology

[0002] Currently, most small table adjustment solutions on the market rely on changes in the angle of the connected object, while the small table itself has limited angle adjustment capabilities. For example, existing technology proposes a motor-driven small table, which can achieve angle adjustment, but it is costly, and the arrangement of the entire chair is difficult due to the small table's rotation around an axis. Existing technology also provides a four-bar linkage small table, which achieves angle adjustment by adjusting the length of the linkage on the fixed side of the table. However, due to the use of linkage adjustment, it also has cost issues, and the operation is not direct enough and lacks convenience.

[0003] In summary, existing table angle adjustment solutions generally suffer from drawbacks such as inconvenient operation and complex adjustment mechanisms, failing to meet users' needs for flexible table angle adjustment. In particular, the comfort and convenience of using the table are greatly reduced when the seat back angle changes.

[0004] No effective solution has yet been proposed to address the aforementioned technical issues. Utility Model Content

It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and therefore their description will be omitted.

[0052] Combination Figures 1 to 12 As shown, according to a specific embodiment of this application, a tabletop assembly is provided.

[0053] Specifically, the table assembly includes a table, a transmission mechanism 200, and a linkage assembly 300. The transmission mechanism 200 includes a support component that is rotatably connected to the table. The linkage assembly 300 includes a first link 311 and a second link 321. The first end of the first link 311 is rotatably connected to the table, and the first end of the second link 321 is rotatably connected to either the table or the transmission mechanism 200. The second ends of both the first link 311 and the second link 321 are rotatably connected to a target object. The support component has a contact position that contacts the first link 311. Rotation of the support component can cause the first link 311 to move relative to the second link 321, thereby adjusting the angle between the table and the target object.

[0054] The above-mentioned optional embodiments of this application can achieve the following beneficial effects: by rotating the support component, the first link 311 can be pushed to move relative to the second link 321, thereby adjusting the angle between the table and the target object, realizing flexible adjustment of the table angle, and improving the user's comfort in different usage scenarios.

[0055] It should be noted that in this embodiment, the target object can be of various types, such as a seat back, seat cushion, or work table.

[0056] Specifically, in the embodiments of this application, the first end of the second link 321 is located between the first end of the first link 311 and the target object. The first link 311 includes a first segment and a second segment connected at an included angle. The first segment and the second segment are rotatably connected to the tabletop and the target object, respectively. The lower surface of the second segment contacts the support assembly. When the support assembly rotates, it pushes the second segment to move up and down, and the first segment drives the tabletop connected to it to rotate, thereby realizing the angle adjustment between the tabletop assembly and the target object. In this embodiment, the connection between the first end of the second link 321 and the tabletop can fix the relative position of the tabletop, that is, control the end of the tabletop closer to the target object to remain fixed, and the first link 311 can be driven by the support assembly to drive the end of the tabletop away from the target object to rotate relative to it.

[0057] The distance between the first end of the first link 311 and the first end of the second link 321, as well as the size of the support assembly, can be adjusted according to actual needs to change the angle adjustment accuracy, angle adjustment range, and stability of the table assembly. For example, when the first end of the first link 311 is close to the target object, it is easier to make fine adjustments to the angle of the table assembly, and the adjustment process is relatively smooth. The further the first end of the first link 311 is from the back of the table and chair, the more obvious the angle change will be during table adjustment, and the table will be adjusted to the target angle more quickly.

[0058] It should be understood that in practical applications, the angle of the target object may also be adjustable, resulting in different optimal usage angles for the table assembly corresponding to the target object at different angles. The optimal usage angle refers to the angle between the table assembly and the target object when the table assembly is in its optimal usage state.

[0059] It should be noted that in this embodiment, the first end of the second link 321 is rotatably connected to either the table or the transmission mechanism 200. That is to say, the first end of the second link 321 can be rotatably connected to either the table or the transmission mechanism 200.

[0060] Furthermore, the distance between the contact position and the rotation connection point of the support component on the table can be varied.

[0061] The above-described optional embodiments of this application can achieve the following beneficial effects: By rotating the support component, the distance between the contact position and the rotation connection point of the support component on the table can be changed, thereby pushing the first link to move relative to the second link, and thus adjusting the angle between the table and the target object, realizing flexible adjustment of the table angle and improving user comfort in different usage scenarios. According to actual needs, the distance between the contact position and the rotation connection point of the support component on the table can be adjusted to any intermediate value between the maximum and minimum values, so that the angle between the table assembly and the target object meets user requirements, for example, adjusting the table to be close to a horizontal state for easier user use.

[0062] Preferably, the support assembly includes a cam 231, which has a contact position that contacts the first link 311, and the cam radius of the contact position can be set variably.

[0063] The above-mentioned optional embodiments of this application can achieve the following beneficial effects: the setting of cam 231 can simplify the structure of the support component and reduce manufacturing costs. The outer peripheral surface of cam 231 contacts the first connecting rod 311. Only by driving cam 231 to rotate can the relative distance between the first connecting rod 311 and the second connecting rod 321 be changed, thereby realizing the adjustment of the table angle.

[0064] The distance between the first end of the first link 311 and the first end of the second link 321, as well as the size of the cam 231, can be adjusted according to actual needs to change the angle adjustment accuracy, angle adjustment range, and stability of the table assembly.

[0065] In one exemplary embodiment of this application, the cam radius at the contact position where the cam 231 contacts the first connecting rod 311 has a maximum value and a minimum value, wherein, for example... Figure 8 and Figure 9As shown, when the cam radius is at its minimum value, the first link 311 is at its lowest position and can contact the upper surface of the second link 321; when the cam radius is at its maximum value, the cam 231 lifts the first link 311 to its highest position, and there is a maximum distance between the first link 311 and the second link 321 (not shown in the figure).

[0066] It should be understood that in practical applications, the angle of the target object may also be adjustable, resulting in different optimal operating angles for the table assembly corresponding to the target object at different angles. The optimal operating angle refers to the angle between the table assembly and the target object when the table assembly is in its best operating state. Depending on actual needs, the cam radius at the contact position can be adjusted to any intermediate value between its maximum and minimum values ​​to ensure that the angle between the table assembly and the target object meets the user's requirements, such as... Figure 10 As shown, at this time, the first link 311 and the second link 321 are a certain distance apart, and the table is close to horizontal, which is convenient for the user to use.

[0067] In an optional embodiment of this application, the support assembly includes a gear and rack assembly, wherein one end of the rack contacts the first connecting rod 311, and rotation of the gear can drive the rack to move along its length, thereby adjusting the distance by which the rack lifts the first connecting rod 311, thus achieving relative position adjustment between the first connecting rod 311 and the second connecting rod 321. The gear is connected to a drive shaft 221, which can drive the gear to rotate synchronously.

[0068] Furthermore, the transmission mechanism 200 also includes a rotating shaft 211, a roller 201, and a transmission shaft 221. The rotating shaft 211 is connected to the tabletop. The roller 201 is sleeved on the rotating shaft 211 and can rotate relative to the rotating shaft 211. The transmission shaft 221 is connected to the cam 231, and the transmission shaft 221 can drive the cam 231 to rotate synchronously. The outer circumferential surfaces of the transmission shaft 221 and the roller 201 are provided with meshing teeth, and the rotation of the roller 201 can drive the transmission shaft 221 and the cam 231 to rotate synchronously.

[0069] The above-mentioned optional embodiments of this application can achieve the following beneficial effects: simply drive the roller 201 to rotate, and the rotational force of the roller 201 can be transmitted to the transmission shaft 221 through gear meshing, thereby driving the cam 231 to rotate, realizing the adjustment of the table angle. The table angle adjustment operation is simple, improving the convenience of table angle adjustment. Users can easily complete it without professional skills. It is suitable for occasions such as reading in the car, dining, and placing electronic devices that require quick and convenient adjustment of the table angle.

[0070] In one exemplary embodiment of this application, such as Figure 6As shown, along the circumferential direction of the roller 201, the roller 201 has an operating section and a meshing tooth section. The meshing tooth section is used to mesh with the meshing tooth section on the transmission shaft 221 for transmission. The operating section can be used to drive the rotation of the roller 201. The user can manually rotate the operating section to drive the rotation of the cam 231.

[0071] In an alternative embodiment of this application, the transmission mechanism 200 may consist only of a cam 231 and a drive motor. The output shaft of the drive motor is connected to the cam 231, and the drive motor can directly drive the cam 231 to rotate, thereby causing the first link 311 to move relative to the second link 321, and adjusting the angle between the table and the target object.

[0072] In another alternative embodiment of this application, the transmission mechanism 200 may include a cam 231, a transmission shaft 221, a belt and a pulley. By driving the pulley to rotate, the belt can be driven to move, which in turn drives the transmission shaft 221 and the cam 231 to rotate, thereby driving the first link 311 to move relative to the second link 321, adjusting the angle between the table and the target object.

[0073] Furthermore, the drive shaft 221 includes a main body section 2211 and a mounting section 2212, wherein the cross-sectional shape of the mounting section 2212 is different from that of the main body section 2211, and the cam 231 has a mounting hole 2310 that matches the mounting section 2212. When the cam 231 is connected to the drive shaft 221, at least a portion of the mounting section 2212 is located within the mounting hole 2310.

[0074] The above-mentioned optional embodiments of this application can achieve the following beneficial effects: by matching the mounting section 2212 with the mounting hole 2310 of the cam 231, a stable connection between the cam 231 and the drive shaft 221 can be ensured, avoiding slippage or loosening during the table angle adjustment process. The table angle adjustment process is more stable, improving the safety and reliability of the table. This makes the table more suitable for occasions such as in-vehicle entertainment, work, and rest where the table needs to stably support items.

[0075] In one exemplary embodiment of this application, such as Figure 5 and Figure 7 As shown, the cross-sectional shape of the mounting section 2212 is polygonal, preferably pentagonal, the cross-sectional shape of the main body section 2211 is circular, and the cross-sectional shape of the mounting hole 2310 of the cam 231 is a matching pentagon. Depending on actual needs, the cross-sectional shapes of the mounting section 2212 and the main body section 2211 can be adjusted to other shapes.

[0076] In an alternative embodiment of this application, the drive shaft 221 and the cam 231 can also be connected by a key and keyway connection. Specifically, a keyway is provided in the mounting hole 2310 of the cam 231, and a key matching the keyway is provided on the mounting section 2212 of the drive shaft 221 to achieve torque transmission. Alternatively, the drive shaft 221 and the cam 231 can be connected using a spline connection. Splines have better torque transmission and self-positioning capabilities, making them suitable for high-precision rotation applications.

[0077] Furthermore, the tabletop includes a cover plate assembly 100 and a frame assembly 400. The cover plate assembly 100 has a receiving space and a movable groove 1001 communicating with the receiving space. The frame assembly 400 is located within the receiving space and a transmission mechanism 200 is provided on the frame assembly 400. The first end of the first connecting rod 311 is rotatably connected to the frame assembly 400, and the first end of the second connecting rod 321 is rotatably connected to either the frame assembly 400 or the transmission mechanism 200. The first connecting rod 311 and the second connecting rod 321 extend to the outside of the cover plate assembly 100 through the movable groove 1001.

[0078] The above-described optional embodiments of this application achieve the following beneficial effects: The design of the movable groove 1001 ensures the relative movement of the first connecting rod 311 and the second connecting rod 321. Utilizing the structure of the cover plate assembly 100 and the frame assembly 400, the transmission mechanism 200 and the connecting rod assembly 300 are concealed inside the cover plate assembly 100. This ensures the aesthetics of the tabletop assembly without affecting its normal use, while also reducing the erosion and interference of external impurities on the transmission mechanism 200 and the connecting rod assembly 300. The tabletop assembly has a simple appearance and a compact internal structure. The cover plate assembly 100 serves as the direct contact surface for the user, ensuring that the user does not perceive the presence of the internal mechanical structure, thus improving the user experience and comfort.

[0079] In this embodiment, the first end of the second link 321 can be rotatably connected to the frame assembly 400 or rotatably connected to the transmission mechanism 200. For example, as Figure 3 As shown, the first end of the second connecting rod 321 has a through hole for the transmission shaft 221 to pass through. The transmission shaft 221 is rotatably connected to the frame assembly 400, and the end of the transmission shaft 221 passes through the through hole at the first end of the second connecting rod 321. The transmission shaft 221 and the second connecting rod 321 maintain rotational freedom. To prevent the transmission shaft 221 from coming out of the through hole, a sealing element can be provided at the end of the transmission shaft 221. In fact, the second connecting rod 321 indirectly achieves a rotatable connection with the frame assembly 400 by rotatably connecting to the transmission shaft 221. Depending on actual needs, the first end of the second connecting rod 321 can also be directly rotatably connected to the frame assembly 400, for example, by directly hinged to the first end of the second connecting rod 321 and the frame assembly 400.

[0080] Furthermore, the cover plate assembly 100 has an opening 1002, through which a portion of the rollers 201 extend to the outside of the cover plate assembly 100.

[0081] The above-described optional embodiments of this application achieve the following beneficial effects: by exposing a portion of the roller 201 through the opening 1002, the user can easily operate the roller 201 directly to adjust the tabletop angle. When the user needs to adjust the tabletop angle manually, the operation is intuitive and convenient, eliminating the need for the user to search for a hidden adjustment mechanism, thus improving the user experience.

[0082] Preferably, the opening 1002 is located on the top surface of the cover assembly 100, which is the surface used for supporting and placing items. Depending on the actual application requirements, the opening 1002 can also be located on the side, bottom, or other positions of the cover assembly 100.

[0083] Furthermore, the frame assembly 400 includes a frame crossbeam 421 and a frame longitudinal beam 401. The transmission mechanism 200 is disposed on the frame crossbeam 421, and the axial direction of the transmission shaft 221 is the same as the extension direction of the frame crossbeam 421. The first end of the first connecting rod 311 is rotatably connected to the frame longitudinal beam 401, and the first end of the second connecting rod 321 is rotatably connected to the transmission shaft 221.

[0084] The above-mentioned optional embodiments of this application can achieve the following beneficial effects: by setting the transmission mechanism 200 on the frame beam 421 and using the structure of the frame beam 421 as the support for the transmission shaft 221, the stability and reliability of the transmission shaft 221 are ensured, the tabletop angle adjustment process is more stable, and the user will not feel the shaking of the internal mechanism of the tabletop when using it, thus improving the user experience.

[0085] Furthermore, the linkage assembly 300 also includes a mounting bracket 301, which is rotatably connected to the second end of the first link 311 and the second end of the second link 321. The mounting bracket 301 is used to connect to the target object.

[0086] The above-described optional embodiments of this application achieve the following beneficial effects: By connecting the connecting rod assembly 300 to the target object through the mounting bracket 301, a stable connection between the tabletop and the target object is ensured, preventing the tabletop from shaking or loosening during use. Simultaneously, since the first connecting rod 311 and the second connecting rod 321 are already connected to the mounting bracket 301, connecting the tabletop assembly to the target object only requires connecting the mounting bracket 301 to the target object, making the connection and disassembly of the tabletop assembly to the target object more convenient.

[0087] Furthermore, there are two connecting rod assemblies 300 and two support components. The two connecting rod assemblies 300 and the two support components are arranged opposite each other along the length of the table, and the two connecting rod assemblies 300 and the two support components are arranged in a one-to-one correspondence.

[0088] The above-described optional embodiments of this application can achieve the following beneficial effects: by using two relatively arranged connecting rod assemblies 300 and support components, the balance and stability of the tabletop when adjusting the angle can be ensured, avoiding tilting or instability of the tabletop when adjusting the angle, thus improving the user experience.

[0089] It should be understood that the number and position of the linkage assembly 300 and the support component can be adjusted according to actual needs. For example, in addition to setting one linkage assembly 300 and one support component at each end of the tabletop along its length, a linkage assembly 300 and a support component can also be added in the middle of the tabletop to further improve the stability of the tabletop adjustment process.

[0090] This application also provides a preferred embodiment of a table assembly to facilitate table angle adjustment, which can be widely used in the field of automotive seats.

[0091] In this embodiment, the table assembly includes a cover plate assembly 100, a transmission mechanism 200, a connecting rod assembly 300, and a frame assembly 400. The cover plate assembly 100 includes an upper cover plate 101, a lower cover plate 102, and a trim strip 103. The transmission mechanism 200 includes a roller 201, a rotating shaft 211, a transmission shaft 221, and a cam 231. The connecting rod assembly 300 includes a mounting bracket 301 for mounting the table assembly to the seat back frame, a first connecting rod 311, a second connecting rod 321, rivets 331, and bolts 341. The frame assembly 400 includes a longitudinal frame beam 401 with a slide rail, a reinforcing crossbeam 411, and a frame crossbeam 421. By rotating the roller 201, the transmission shaft 221 and the cam 231 rotate, thereby changing the relative position of the upper and lower connecting rods (i.e., the first connecting rod 311 and the second connecting rod 321), thus adjusting the table angle.

[0092] Specifically, the table assembly is mounted on the seat back via mounting bracket 301 and is linked to the seat back; one end of the first connecting rod 311 is connected to the mounting bracket 301 via rivet 331 and retains rotational freedom, and the other end is connected to the frame longitudinal beam 401 via bolt 341 and retains rotational freedom; one end of the second connecting rod 321 is connected to the mounting bracket 301 via rivet 331 and retains rotational freedom, and the other end is connected to the drive shaft 221 via bolt 341 and retains rotational freedom; the roller 201 is coaxial with the rotating shaft 211 and retains rotational freedom; the rotating shaft 211 is fixedly connected to the frame crossbeam 421; as shown Figure 5 and Figure 7As shown, the roller 201 meshes with the gear teeth in the middle of the transmission shaft 221. The end section of the transmission shaft 221 is polygonal, which matches the polygonal hole of the cam 231 to achieve transmission. At the same time, the end of the transmission shaft 221 matches the longitudinal beam 401 of the skeleton to maintain rotational freedom.

[0093] The working principle of the table assembly in this embodiment is as follows:

[0094] When the table assembly is in use, such as Figure 8 , Figure 9 As shown, due to the angle of the seat back, the tabletop angle is downward. At this time, the roller 201 can be rolled, driving the transmission shaft 221 to rotate via gear meshing. The transmission shaft 221 drives the cam 231 to rotate around its axis. The cam 231 contacts the bottom surface of the first connecting rod 311. When the cam 231 rotates around its axis, the radius of the cam at the contact point with the first connecting rod 311 increases, thereby raising the first connecting rod 311. This change in the relative position of the first connecting rod 311 and the second connecting rod 321 raises the tabletop angle. Figure 10 , Figure 11 , Figure 12 As the cam 231 rotates, the position of the first connecting rod 311 rises, and the table angle is adjusted, gradually transitioning from downward angle to horizontal angle and then upward angle.

[0095] Conversely, such as Figure 12 As shown, when the seat back angle is adjusted in the reverse direction, the table angle is upward. At this time, the roller 201 can be rolled in the reverse direction, driving the transmission shaft 221 to rotate through gear meshing. The transmission shaft 221 drives the cam 231 to rotate around the shaft. The cam 231 contacts the bottom surface of the first connecting rod 311. When the cam 231 rotates around the shaft, the cam radius at the contact position with the first connecting rod 311 decreases, thereby lowering the first connecting rod 311. This changes the relative position of the first connecting rod 311 and the second connecting rod 321, thus lowering the table angle. Figure 12 , Figure 11 , Figure 10 As cam 231 rotates in the opposite direction, the cam radius at the contact position decreases, and the table gradually transitions from upward to horizontal and downward angle.

[0096] The table assembly in this embodiment can solve the problem of non-adjustable seat table angle at a low cost. Moreover, the seat table angle adjustment in this embodiment is convenient and simple, with great practical value and high future application prospects.

[0097] According to another specific embodiment of this application, a seat assembly is also provided, which includes a seat and a table assembly, wherein the table assembly is the table assembly in the above embodiment, and the target object is the seat back of the seat.
