Detailed Implementation
[0024] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0025] The following is for reference. Figures 1-8 A folding table device 100, a seating system, and a vehicle are described according to embodiments of the present invention.
[0026] A folding tabletop device 100 according to an embodiment of the present invention includes: Linkage assembly 10 and table 20, the linkage assembly 10 being rotatably connected between table 20 and adapter to move the folding table device 100 to a folded position or an unfolded position; A protective structure 30 is provided on the tabletop 20. At least one side of the linkage assembly 10 is provided with the protective structure 30. The protective structure 30 has a blocking state. In the blocking state, the protective structure 30 protrudes from the tabletop 20 to at least block the end of the linkage assembly 10 near the tabletop 20.
[0027] The folding tabletop device 100 includes a linkage assembly 10 and a tabletop 20. The linkage assembly 10 is rotatably connected between the tabletop 20 and the adapter, allowing the folding tabletop device 100 to move to a folded or unfolded position for easy use and storage. Specifically, the linkage assembly 10 can be rotatably connected to both the tabletop 20 and the adapter. In some embodiments of the invention, the linkage assembly 10 can be rotatably connected to both the tabletop 20 and the adapter via a pivot, or the tabletop 20 and the adapter can be rotatably connected via a hinge. However, the invention is not limited to these methods; the linkage assembly 10 can be rotatably connected to both the tabletop 20 and the adapter in other ways, as long as the linkage assembly 10 is rotatably connected between the tabletop 20 and the adapter to allow the folding tabletop device 100 to move to a folded or unfolded position.
[0028] The compatible parts can be vehicle seats 200, cabinets, workbenches, and other structures suitable for installing the folding table device 100, and can be reasonably set according to the actual situation.
[0029] The protective structure 30 can be constructed as a protective baffle, a protective cover, or other structures. The protective structure 30 is disposed on the tabletop 20. At least one side of the connecting rod assembly 10 is provided with the protective structure 30. In some embodiments of the present invention, the outer side of the connecting rod assembly 10 (referring to the side away from the center of the tabletop 20) can be provided with the protective structure 30, or the inner side of the connecting rod assembly 10 (referring to the side close to the center of the tabletop 20) can be provided with the protective structure 30, or both the inner and outer sides of the connecting rod assembly 10 can be provided with the protective structure 30, as long as at least one side of the connecting rod assembly 10 is provided with the protective structure 30.
[0030] In a specific embodiment of the present invention, a protective structure 30 is provided on the outer side of the linkage assembly 10. The protective structure 30 has a blocking state. In the blocking state, the protective structure 30 protrudes from the tabletop 20 to at least block the end of the linkage assembly 10 near the tabletop 20. During the rotation of the tabletop 20, a gap (commonly known as a scissor zone) is formed at the end of the linkage assembly 10 near the tabletop 20, which changes angle with the rotation of the tabletop 20. If a finger happens to be placed in this gap, as the tabletop 20 folds, the finger will be clamped by a strong mechanical force. This can cause bruising and severe pain, and in severe cases, fractures or fingertip injuries. In the shielded state, the protective structure 30 protrudes from the tabletop 20 to at least shield the end of the linkage assembly 10 near the tabletop 20, thus blocking the gap. This effectively prevents the user's fingers from being pinched when flipping the tabletop 20, and also prevents nearby children from accidentally putting their fingers into the gap of the linkage assembly 10 and getting pinched. The protective structure 30 actively prevents the user from putting their fingers or other parts into the gap of the linkage assembly 10, effectively preventing the user from being pinched.
[0031] Therefore, the protective structure 30 can transform the "passive warning" of posting signs into "active protection", preventing the user's fingers and other parts from entering the scissor area, effectively avoiding the phenomenon of the linkage assembly 10 pinching the user's fingers and other parts, and thus better ensuring the user's safety.
[0032] The folding tabletop device 100 according to an embodiment of the present invention, by providing a protective structure 30 on the tabletop 20, and having a protective structure 30 on at least one side of the connecting rod assembly 10, the protective structure 30 has a blocking state. In the blocking state, the protective structure 30 protrudes from the tabletop 20 to at least block the end of the connecting rod assembly 10 near the tabletop 20. This transforms the "passive warning" of posting signs into "active protection," preventing the user's fingers or other parts from entering the scissor area, effectively avoiding the phenomenon of the connecting rod assembly 10 pinching the user's fingers or other parts, thereby better ensuring the user's safety.
[0033] According to some embodiments of the present invention, such as Figures 1-4As shown, the protective structure 30 is movably disposed on the tabletop 20 to move relative to the tabletop 20 to a retracted state or a shielded state. In the retracted state, the protective structure 30 is housed within the tabletop 20. In the shielded state, at least a portion of the protective structure 30 is exposed on the tabletop 20 to shield the linkage assembly 10.
[0034] Among them, such as Figure 4 As shown, the protective structure 30 is movably disposed on the tabletop 20 to move relative to the tabletop 20 to a retracted state or a shielding state. The protective structure 30 can move along the thickness direction of the tabletop 20 to achieve the retracted or shielding state. Furthermore, the protective structure 30 can be driven to move by a motor, elastic structure, or other driving component to achieve the retracted or shielding state relative to the tabletop 20.
[0035] In the stowed state, the protective structure 30 is housed within the tabletop 20. At this time, the tabletop 20 is in an unfolded state for user use, and the protective structure 30 is flush with the tabletop 20 and does not protrude from the tabletop 20. The user will not be pressured by the protruding edge of the protective structure 30, and the protective structure 30 can also prevent the user from being bumped by the user.
[0036] In the shielded state, at least a portion of the protective structure 30 is exposed on the tabletop 20 to shield the scissor area of the linkage assembly 10, which can effectively prevent the user's fingers or other parts from being pinched by the linkage assembly 10, thereby better ensuring the user's safety and allowing the user to use the tabletop 20 with more peace of mind and relaxation.
[0037] According to some embodiments of the present invention, such as Figures 1-3 As shown, the linkage assembly 10 is configured to drive the protective structure 30 to move from a covered state to a stowed state during the movement of the folding table device 100 from a folded position to an unfolded position.
[0038] During the movement of the folding tabletop device 100 from the folded position to the unfolded position, the rotation of the linkage assembly 10 toward the bottom wall of the tabletop 20 generates a downward force on the protective structure 30, thereby driving the protective structure 30 to move from above the tabletop 20 into the interior of the tabletop 20. This allows the protective structure 30 to move from the blocking state to the storage state, ensuring that the protective structure 30 remains in the blocking state throughout the folding and unfolding processes of the tabletop 20. This effectively prevents users' fingers from being pinched when flipping the tabletop 20 and inserting them into the gaps of the linkage assembly 10. It also prevents nearby children from accidentally inserting their fingers into the gaps of the linkage assembly 10 and getting pinched. The protective structure 30 actively prevents users from inserting their fingers or other body parts into the gaps of the linkage assembly 10, effectively avoiding user injuries.
[0039] When the tabletop 20 is fully extended and in the extended position, the protective structure 30 is in the retracted state. The protective structure 30 is housed within the tabletop 20 and is flush with the tabletop 20 without protruding. The user will not be pressured by the protruding edge of the protective structure 30, and the protective structure 30 can also prevent the user from being bumped or hit by the user, thus ensuring the user's comfort.
[0040] According to some embodiments of the present invention, such as Figure 4 As shown, the tabletop 20 has a first receiving groove 21. The protective structure 30 is movably disposed in the first receiving groove 21 along the depth direction of the first receiving groove 21. The protective structure 30 is fixedly provided with a drive shaft 31. The linkage assembly 10 drives the drive shaft 31 to move the protective structure 30 into the first receiving groove 21, so that the protective structure 30 moves from the blocking state to the storage state.
[0041] The tabletop 20 has a first receiving groove 21. For example, the upper end of the first receiving groove 21 is open and extends downward along the thickness direction of the tabletop 20. The protective structure 30 is movably disposed in the first receiving groove 21 along the depth direction of the first receiving groove 21, so that when the protective structure 30 is accommodated in the first receiving groove 21, it can be flush with the upper surface of the tabletop 20, so as to avoid the protective structure 30 from blocking the upper surface of the tabletop 20, thereby further preventing the protective structure 30 from bumping into the user and improving the user's comfort.
[0042] The protective structure 30 is fixedly provided with a drive shaft 31. In some embodiments of the present invention, the protective structure 30 and the drive shaft 31 can be integrally formed, or the protective structure 30 and the drive shaft 31 can be fixedly connected by welding. However, the present invention is not limited to this. The protective structure 30 and the drive shaft 31 can also be fixedly connected by other means, as long as the protective structure 30 is fixedly provided with a drive shaft 31.
[0043] The linkage assembly 10 drives the drive shaft 31 to move the protective structure 30 into the first receiving groove 21, so that the protective structure 30 moves from the blocking state to the storage state. Specifically, during the process of rotating the tabletop 20 from the folded position to the unfolded position, the linkage assembly 10 rotates along the depth direction of the first receiving groove 21 toward the bottom wall of the tabletop 20. During the rotation of the linkage assembly 10, it can press against the drive shaft 31, thereby driving the drive shaft 31 to move into the first receiving groove 21 along the depth direction of the first receiving groove 21. This, in turn, can drive the protective structure 30 to move into the first receiving groove 21, so that the protective structure 30 moves from the blocking state to the storage state. During this process, the protective structure 30 can not only prevent the linkage assembly 10 from pinching the user, but also hide inside the tabletop 20 when the tabletop 20 is rotated to the unfolded position, maintaining the flatness of the tabletop 20 and preventing the protective structure 30 from bumping into the user. The user will also not be pressured by the protruding edge of the protective structure 30, thereby further improving the user's comfort and the aesthetics of the tabletop 20.
[0044] According to some embodiments of the present invention, such as Figure 4 As shown, along the thickness direction of the tabletop 20, a first receiving groove 21 is formed on one side of the tabletop 20, and a second receiving groove 22 is also formed on the tabletop 20. The second receiving groove 22 and the first receiving groove 21 are arranged along the arrangement direction of the protective structure 30 and the connecting rod assembly 10. The end of the connecting rod assembly 10 near the tabletop 20 extends into the second receiving groove 22 and is rotatably connected to the tabletop 20. The drive shaft 31 extends along the arrangement direction of the protective structure 30 and the connecting rod assembly 10 and extends into the second receiving groove 22, so that the connecting rod assembly 10 can drive the protective structure 30 to move into the first receiving groove 21.
[0045] Along the thickness direction of the tabletop 20, a first receiving groove 21 is formed on one side of the tabletop 20, and a second receiving groove 22 is also formed on the tabletop 20. The upper ends of the first receiving groove 21 and the second receiving groove 22 are both open, and the end of the second receiving groove 22 facing the adapter is also open, so as to avoid and accommodate the protective structure 30 and the connecting rod assembly 10 respectively, so that the protective structure 30 and the connecting rod assembly 10 can move smoothly during the rotation of the tabletop 20.
[0046] The second receiving groove 22 and the first receiving groove 21 are arranged along the arrangement direction of the protective structure 30 and the connecting rod assembly 10. The first receiving groove 21 is correspondingly arranged with the protective structure 30, and the second receiving groove 22 is correspondingly arranged with the connecting rod assembly 10. The first receiving groove 21 and the second receiving groove 22 are respectively used to avoid and accommodate the protective structure 30 and the connecting rod assembly 10, so that the protective structure 30 and the connecting rod assembly 10 can move smoothly during the rotation of the table 20.
[0047] The end of the linkage assembly 10 near the tabletop 20 extends into the second receiving groove 22 and is rotatably connected to the tabletop 20. The drive shaft 31 extends along the arrangement direction of the protective structure 30 and the linkage assembly 10 and extends into the second receiving groove 22. The drive shaft 31 is in contact with the linkage assembly 10, so that the linkage assembly 10 can drive the protective structure 30 to move into the first receiving groove 21 during the rotation of the linkage assembly 10 toward the depth direction of the second receiving groove 22. Thus, the tabletop 20 can gradually move into the first receiving groove 21 during the rotation of the tabletop 20 from the folded position to the unfolded position. This not only ensures that the protective structure 30 always covers the end of the linkage assembly 10 near the tabletop 20 (i.e., the aforementioned scissor area) during the rotation of the tabletop 20, but also allows the protective structure 30 to be hidden inside the tabletop 20 when the tabletop 20 is rotated to the unfolded position, maintaining the flatness of the tabletop 20. This prevents the protective structure 30 from bumping into the user, and the user will not be pressured by the protruding edge of the protective structure 30, thereby further improving the user's comfort and the aesthetics of the tabletop 20.
[0048] According to some embodiments of the present invention, such as Figure 3 As shown, when the folding tabletop device 100 is moved to the unfolded position, the connecting rod assembly 10 does not protrude from the surface of the tabletop 20 along the thickness direction of the tabletop 20; or When the folding table device 100 moves to the unfolded position, the connecting rod assembly 10 protrudes from the surface of the table 20 along the thickness direction of the table 20.
[0049] When the folding tabletop device 100 is moved to the unfolded position, the connecting rod assembly 10 does not protrude from the surface of the tabletop 20 along the thickness direction of the tabletop 20. This allows the connecting rod assembly 10 to be hidden inside the tabletop 20, maintaining the flatness of the tabletop 20. This prevents the connecting rod assembly 10 from bumping into the user, and the user will not be pressured by the protruding edge of the connecting rod assembly 10, thereby further improving the user's comfort and the aesthetics of the tabletop 20.
[0050] Alternatively, when the folding table device 100 is moved to the unfolded position, the connecting rod assembly 10 protrudes from the surface of the table 20 along the thickness direction of the table 20. This configuration allows the use of a simple standard pivot and locking mechanism, eliminating the need for a complex built-in telescopic or sinking structure, which helps reduce the manufacturing cost of the folding table device 100.
[0051] According to some embodiments of the present invention, such as Figures 6-8 As shown, the tabletop 20 has a partition wall 23 located between the first receiving groove 21 and the second receiving groove 22. The partition wall 23 has a guide hole 24 extending along the depth direction of the first receiving groove 21. The guide hole 24 connects the first receiving groove 21 and the second receiving groove 22. The drive shaft 31 passes through the guide hole 24, which guides the movement direction of the drive shaft 31.
[0052] The tabletop 20 has a partition wall 23 located between the first receiving groove 21 and the second receiving groove 22. In one embodiment of the present invention, the partition wall 23 can be the groove side wall of the second receiving groove 22 near the first receiving groove 21. The groove side wall of the first receiving groove 21 near the second receiving groove 22 has a clearance hole. The partition wall 23 is formed with a guide hole 24 extending along the depth direction of the first receiving groove 21. The guide hole 24 connects the first receiving groove 21 and the second receiving groove 22. The drive shaft 31 passes through the guide hole 24 to connect the drive shaft 31 to the protective structure 30. The guide hole 24 is used to guide the movement direction of the drive shaft 31. The orientation and shape of the guide hole 24 are set according to the movement trajectory of the drive shaft 31 and are not specifically limited.
[0053] By setting guide holes 24 to guide the movement direction of drive shaft 31, it can be ensured that drive shaft 31 moves along a predetermined trajectory, ensuring the accuracy of power transmission. This allows the protective structure 30 to be accurately and smoothly stored in the first receiving groove 21 under the stable drive of drive shaft 31, avoiding the risk of jamming or interference caused by movement deviation, and significantly improving the stability and smoothness of the retraction and extension of the protective structure 30.
[0054] In some embodiments of the present invention, the outer surface of the drive shaft 31 may be covered with a buffer layer. The buffer layer may be made of damping materials such as rubber or foam, and the specific material of the buffer layer may be reasonably selected and set according to actual conditions. By covering the outer surface of the drive shaft 31 with a buffer layer, the axial or radial impact force of the drive shaft 31 during movement and start-stop can be effectively absorbed, preventing the drive shaft 31 from bending or fatigue damage due to instantaneous overload, and extending the service life of the drive shaft 31 and the entire transmission system. Furthermore, the buffer layer has a certain elasticity, which can fill the small gap between the drive shaft 31 and the guide hole 24, eliminating the radial wobble of the drive shaft 31 in the guide hole 24, ensuring that the drive shaft 31 moves strictly according to the trajectory of the guide hole 24, thereby improving the positioning accuracy and stability of the protective structure 30 when it moves into the first receiving groove 21. The frictional resistance between the drive shaft 31 and the wall of the guide hole 24 is reduced, making the movement of the drive shaft 31 more effortless and smoother. At the same time, the buffer layer, as a "sacrificial layer," preferentially bears wear, protecting the more expensive drive shaft 31 and the partition wall 23.
[0055] The elastic deformation capacity of the buffer layer can also accommodate minor manufacturing and installation errors, compensating for machining and assembly errors in the drive shaft 31 and guide hole 24. The buffer layer can also block the path of vibration transmission from the drive shaft 31 to the partition wall 23. Simultaneously, it avoids the "creaking" or high-frequency howling that may occur when metals are in direct contact, thus playing a role in vibration isolation and noise reduction, which is beneficial to improving the NVH performance of the folding table device 100.
[0056] According to some embodiments of the present invention, such as Figure 4 , Figure 7 and Figure 8 As shown, the folding table device 100 also includes a drive structure 40, which is disposed on the table 20 and is used to drive the protective structure 30 from the stored state to the shielded state.
[0057] The drive structure 40 can be a motor, an elastic structure, a pneumatic component, etc., and can be reasonably selected and set according to the actual situation. The drive structure 40 is set on the table 20 and is used to drive the protective structure 30 from the storage state to the blocking state, so that the protective structure 30 can be moved out of the first receiving groove 21 to block the end of the connecting rod assembly 10 near the table 20, thereby realizing the function of the protective structure 30 preventing the connecting rod assembly 10 from pinching the hand.
[0058] In some embodiments of the present invention, the drive structure 40 is an elastic structure and is assembled with the drive shaft 31. The elastic structure can be a spring, torsion spring 41, or other elastic structures, which can be reasonably selected and set according to actual conditions. Specifically, when the linkage assembly 10 drives the drive shaft 31 to move into the first receiving groove 21 along the depth direction of the first receiving groove 21, the elastic structure is compressed. When the linkage assembly 10 separates from the drive shaft 31 and moves out of the second receiving groove 22, the elastic structure recovers its elastic force to lift the drive shaft 31, thereby driving the protective structure 30 out of the first receiving groove 21. This ensures that the drive shaft 31 can quickly and reliably drive the protective structure 30 out of the first receiving groove 21, effectively avoiding mechanism jamming. At the same time, it eliminates the need for a complex bidirectional drive mechanism, simplifies the control process, and reduces manufacturing costs.
[0059] As a specific embodiment of the present invention, the elastic structure can be connected between the protective structure 30 and the bottom wall of the first receiving groove 21. When the connecting rod assembly 10 drives the drive shaft 31 to move towards the first receiving groove 21 along the depth direction of the first receiving groove 21, it can drive the protective structure 30 to move towards the first receiving groove 21 and compress the elastic structure. When the connecting rod assembly 10 is separated from the drive shaft 31, neither the drive shaft 31 nor the protective structure 30 is under force, and the elastic structure resets to eject the protective structure 30 from the first receiving groove 21.
[0060] According to some embodiments of the present invention, such as Figure 7 and Figure 8 As shown, the elastic structure is a torsion spring 41, which is sleeved on the drive shaft 31. The torsion spring 41 has two connecting ends 42, which are respectively fixed to the protective structure 30 and the table 20. When the protective structure 30 is in the blocking state, the torsion spring 41 is compressed to keep the protective structure 30 in the blocking state.
[0061] The elastic structure can be a torsion spring 41, which is sleeved on the drive shaft 31. The torsion spring 41 has two connecting ends 42, which are respectively fixed to the protective structure 30 and the table 20. Along the depth direction of the second receiving groove 22, one connecting end 42 of the torsion spring 41 can be connected to the bottom end of the partition wall 23 of the table 20, and the other connecting end 42 of the torsion spring 41 can be connected to the lower end of the protective structure 30. When the protective structure 30 is in the shielded state, the torsion spring 41 is pre-loaded with energy, so that the torsion spring 41 is compressed to keep the protective structure 30 in the shielded state. This can buffer the accidental impact on the protective structure 30, disperse stress, and reduce the risk of permanent deformation or breakage of the torsion spring 41. After being pre-tightened, the torsion spring 41 is in an energy-storing state from the beginning. It can immediately release the elastic force the moment the downward pressure disappears, so that the drive shaft 31 can quickly spring up and respond more quickly. It can also ensure that the torsion spring 41 has enough initial elastic force to overcome resistance and ensure that the drive shaft 31 can accurately return to its original position every time.
[0062] When the linkage assembly 10 drives the drive shaft 31 to move into the first receiving groove 21, it can further compress the torsion spring 41 and move the protective structure 30 into the first receiving groove 21 so that the protective structure 30 is in the stored state. At this time, the tabletop 20 is flat for user use. When the tabletop 20 is no longer needed and is rotated towards the folding position, the linkage assembly 10 moves out of the second receiving groove 22 and separates from the drive shaft 31. At this time, the torsion spring 41 attempts to return to its original shape. This tendency to return translates into a force that drives the drive shaft 31 to move out of the first receiving groove 21, thereby pushing the drive shaft 31 and the protective structure 30 back to the shielded state.
[0063] Therefore, during the rotation of the tabletop 20 in the folded position and between the folded and unfolded positions, the protective structure 30 remains in a blocking state. During the appearance of the scissor area of the linkage assembly 10, the protective structure 30 always blocks the scissor area, thus transforming the "passive warning" of posting signs into "active protection," preventing the user's fingers and other parts from entering the scissor area, effectively avoiding the phenomenon of the linkage assembly 10 pinching the user's fingers and other parts, and thus better ensuring the user's safety.
[0064] According to some embodiments of the present invention, such as Figure 2 As shown, there are two linkage assemblies 10. The two linkage assemblies 10 are arranged along the protective structure 30 and the arrangement direction of the linkage assemblies 10. Each linkage assembly 10 has a protective structure 30 on the side opposite to the other linkage assembly 10.
[0065] There are two linkage assemblies 10, each including a first linkage 11 and a second linkage 12. The first linkage 11 and the second linkage 12 are arranged along the arrangement direction of the protective structure 30 and the linkage assembly 10. The first linkage 11 is located above the second linkage 12. The end of the second linkage 12 facing the tabletop 20 can always be located in the second receiving groove 22. The end of the first linkage 11 facing the tabletop 20 moves towards the second receiving groove 22 during the process of the tabletop 20 turning from the folded position to the unfolded position. During this process, the gap between the first linkage 11 and the second linkage 12 becomes smaller and smaller. If the user's finger is inserted into this gap, as the tabletop 20 rotates, the finger will be pinched by a strong mechanical force, which may cause bruising and severe pain, or even fracture or fingertip crush injury.
[0066] Each link assembly 10 has a protective structure 30 on the side opposite to the other link assembly 10. In the blocking state, the protective structure 30 protrudes from the tabletop 20 to at least block the end of the link assembly 10 near the tabletop 20. This can block the gap between the first link 11 and the second link 12, thereby effectively preventing the user's fingers from being pinched when the tabletop 20 is flipped. It can also prevent children nearby from accidentally putting their fingers into the gap of the link assembly 10 and getting pinched. The protective structure 30 can actively prevent the user from putting their fingers or other parts into the gap of the link assembly 10, effectively preventing the user from being pinched.
[0067] Furthermore, two sets of connecting rod assemblies 10 are connected between the tabletop 20 and the adapter. The two sets of connecting rod assemblies 10 are arranged along the width direction of the tabletop 20 to ensure a stable connection between the tabletop 20 and the adapter, and also to ensure the stability of the tabletop 20.
[0068] A seating system according to an embodiment of the present invention includes: Seat 200 The folding tabletop device 100, as described in the above embodiment, has a linkage assembly 10 rotatably connected between the tabletop 20 and the backrest of the seat 200, establishing a motion linkage between the seat 200 and the tabletop 20. This enables coordinated posture adjustment, meeting the user's needs for using the tabletop 20 while also facilitating its storage, saving space and making its use more convenient. Furthermore, by providing a protective structure 30 on the tabletop 20, with at least one side of the linkage assembly 10 having a shielding state, the protective structure 30 protrudes from the tabletop 20 to at least shield the end of the linkage assembly 10 near the tabletop 20. This transforms the "passive warning" of posting signs into "active protection," preventing the user's fingers or other parts from entering the scissor area, effectively avoiding the possibility of the linkage assembly 10 pinching the user's fingers or other parts, thus better ensuring user safety.
[0069] The vehicle according to embodiments of the present invention includes the folding table device 100 of the above embodiments or the seat system of the above embodiments. By providing a protective structure 30 on the table 20, and having a protective structure 30 on at least one side of the linkage assembly 10, the protective structure 30 has a blocking state. In the blocking state, the protective structure 30 protrudes from the table 20 to at least block the end of the linkage assembly 10 near the table 20. This transforms the "passive warning" of posting signs into "active protection," preventing the user's fingers or other parts from entering the scissor area, effectively avoiding the phenomenon of the linkage assembly 10 pinching the user's fingers or other parts, thereby better ensuring the user's safety and improving the safety and comfort of the vehicle.
