[0028] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0029] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0030] Please see Figures 1-17The car seat table 100 provided in the embodiments of this utility model can effectively improve the aforementioned technical problems. The car seat table 100 can be folded and extended as a single piece, providing a larger desktop; it provides a spacious and stable surface when needed, and can be quickly and neatly folded away when not in use, balancing practicality, aesthetics, and user experience. The car seat table 100 can be applied to the backrests of seats in cars, airplanes, and other vehicles, or to home seats, and is not limited thereto. Seats with the car seat table 100, as well as cars, airplanes, and other vehicles with the aforementioned seats, all have the same functions, and will not be described in detail here.

[0031] Please see Figure 2 , Figure 6 , Figure 10 and Figure 14 In this embodiment, the car seat 1000 includes a seat back 200 and a car seat table 100. The car seat table 100 is disposed on the back of the seat back 200, and the fixing seat 130 is connected to the seat back 200. In use, the car seat table 100 can be folded and unfolded as a whole relative to the seat back 200 and can also be extended as a whole to meet usage needs.

[0032] Please see Figures 1-17In this embodiment, the car seat table 100 includes a table assembly 110, a connecting frame 120, a fixed seat 130, and a flipping mechanism 140. The table assembly 110 has an installation space 111 inside. The connecting frame 120 is disposed in the installation space 111 and is slidably connected to the table assembly 110, so that the table assembly 110 extends or retracts along the sliding direction. The fixed seat 130 is used to connect to the seat back 200. One end of the flipping mechanism 140 is rotatably connected to the fixed seat 130, and the other end of the flipping mechanism 140 is connected to the connecting frame 120. The flipping mechanism 140 can rotate relative to the fixed seat 130, thereby driving the table assembly 110 to flip as a whole through the connecting frame 120, so as to realize the switching between the unfolded state and the folded state of the table assembly 110. Through the sliding connection, the table assembly 110 can flexibly adjust its effective usable area; it can extend when needed to provide a larger effective desktop; and it can retract when not needed to save space and avoid hindering passenger movement. Compared to drawer-style telescopic tables, the tabletop 100 of this car seat does not crack when unfolded, improving overall aesthetics and safety. Furthermore, the aforementioned structural design allows forces to be transferred through the tabletop assembly 110 to the connecting frame 120, and then directly to the fixed seat 130 connected to the seat back 200 via the flipping mechanism 140, forming a stable multi-link support structure. Compared to drawer-style tables that extend to form cantilever beams, this design improves load-bearing capacity and stability, effectively reducing swaying. In addition, when folded, the tabletop assembly 110 can be tightly folded and fitted against the back of the seat back 200, maintaining a flat and aesthetically pleasing surface. Moreover, the tabletop 100 is easy to operate; the operator can unfold, extend, and fold it with one hand, making it convenient to use.

[0033] The effective usable area of ​​the tabletop assembly 110 mentioned above is the area of ​​the tabletop area where the projection of the seat back 200 onto the plane of the tabletop assembly 110 does not overlap with the tabletop. Please refer to [link / reference]. Figure 1 In the figure, L represents the effective usable length of the tabletop. With a fixed tabletop width, the effective usable area of ​​the tabletop depends on its effective usable length L. In this embodiment, the tabletop 100 of the car seat can have its effective usable length L extended, thus allowing the tabletop assembly to flexibly adjust its effective usable area.

[0034] Please see Figures 20-23 and combined Figure 34In this embodiment, the tabletop assembly 110 includes an upper shell 113, a lower shell 114, and a tabletop frame 115. The upper shell 113 and the lower shell 114 are connected and enclose an installation space 111. The tabletop frame 115 is disposed in the installation space 111 and is fixedly connected to at least one of the upper shell 113 and the lower shell 114. The connecting frame 120 is slidably connected to the tabletop frame 115. Specifically, in this embodiment, the upper shell 113 is fixedly connected to the tabletop frame 115 by threaded fasteners, which can be screws, bolts, etc., and are not limited here. To improve the connection strength and tensile performance, in this embodiment, the upper shell 113 is connected to the tabletop frame 115 by PT screws (self-tapping screws). PT screws have excellent anti-loosening performance, and their pitch design increases the clamping load, enhancing connection reliability and extending service life by reducing surface pressure and preload loss. Of course, the upper shell 113 can also be connected to the tabletop frame 115 by snap-fit, welding, or other methods, and are not limited here. In addition, the table frame 115 can also be fixedly connected to the lower shell 114, or simultaneously fixedly connected to both the upper shell 113 and the lower shell 114, which is not limited here.

[0035] For ease of installation and disassembly, the lower housing 114 in this embodiment is snapped into the upper housing 113. Of course, the lower housing 114 can also be connected to the upper housing 113 by threaded fasteners or by other connection methods such as plug-in, which is not limited here.

[0036] Specifically, the car seat table 100 in this embodiment also includes a sliding guide mechanism 150, and the connecting frame 120 is slidably connected to the table assembly 110 through the sliding guide mechanism 150.

[0037] Optionally, please refer to Figures 24-28 In this embodiment, the sliding guide mechanism 150 includes a slide rail 151 and a slider 152. One of the slide rail 151 and the slider 152 is fixedly connected to the table assembly 110, and the other of the slide rail 151 and the slider 152 is fixedly connected to the connecting frame 120. The slide rail 151 and the slider 152 are slidably engaged, so that the slide rail 151 can move relative to the slider 152 in the sliding direction, thereby causing the table assembly 110 to extend or retract in the sliding direction. Specifically, the slide rail 151 can be fixedly connected to the table assembly 110, and the slider 152 can be fixedly connected to the connecting frame 120, with the slide rail 151 sliding relative to the slider 152; or the slider 152 can be fixedly connected to the table assembly 110, and the slide rail 151 can be fixedly connected to the connecting frame 120, with the slider 152 sliding relative to the slide rail 151.

[0038] The slide rail 151 and slider 152 are precision guiding components that ensure smooth, jam-free, and noiseless movement of the tabletop assembly 110 during extension and retraction. They also effectively prevent the tabletop from wobbling or tilting during movement, providing users with a high-end and reliable user experience. The slide rail 151 has high strength and rigidity, which can more evenly distribute the load from the tabletop surface, significantly improving the tabletop's load-bearing capacity in the extended state.

[0039] To prevent the table assembly 110 from accidentally detaching during extension or retraction, please refer to... Figure 28 and combined Figure 18 and Figure 19 In this embodiment, a limiting member 153 is provided on the rail. The limiting member 153 includes a first limiting member 1531 and a second limiting member 1532 spaced apart along the length direction of the slide rail 151, so that the slider 152 is constrained to reciprocate between the first limiting member 1531 and the second limiting member 1532. In this embodiment, the second limiting member 1532 is closer to the fixed seat 130 than the first limiting member 1531. The first limiting member 1531 restricts the maximum extended position of the table assembly 110, and the second limiting member 1532 restricts the fully retracted position of the table assembly 110, so as to ensure that the table assembly 110 always works within a preset safety range, thereby preventing the slide rail 151 from slipping off the slider 152, and thus improving the safety and reliability of the car seat table 100. In order to avoid the movement of the connecting frame 120 and the flipping mechanism 140, there is a relative height difference between the first limiting member 1531 and the second limiting member 1532. In this embodiment, the height of the second limiting member 1532 is lower than the height of the first limiting member 1531.

[0040] Please continue reading. Figure 28 To reduce the impact force when the slide rail 151 contacts the limiting member 153, grooves are provided at both ends of the slider 152 in this embodiment. Each groove is used to cooperate with the corresponding limiting member 153 when the slider 152 moves to the end of its stroke to achieve motion limiting. The groove design allows the limiting member 153 to "embed" into the slider 152 at the end position, achieving more precise positioning. The structure guides and disperses the impact force, making the limiting action smoother, quieter, and more reliable. The groove structure also increases the effective contact area between the slider 152 and the limiting member 153, reducing the pressure on the contact surface, reducing wear after long-term use, and improving durability. When the groove cooperates with the limiting member 153, a unique "sense of positioning" is produced, usually accompanied by a crisp "click" sound and clear tactile feedback. This tactile and auditory feedback greatly enhances the user's operating feel and user experience.

[0041] Please see Figures 29-32Optionally, the sliding guide mechanism 150 in this embodiment includes a first slide groove 154 and a limiting pin 155. One of the connecting frame 120 and the table assembly 110 is provided with the first slide groove 154 extending in the sliding direction, and the other of the connecting frame 120 and the table assembly 110 is provided with the limiting pin 155. The first slide groove 154 and the limiting pin 155 are configured such that the movement of the limiting pin 155 along the first slide groove 154 causes the table assembly 110 to extend or retract relative to the connecting frame 120 in the sliding direction. In this embodiment, the connecting frame 120 is provided with the first slide groove 154 extending in the sliding direction, and the table assembly 110 is provided with the limiting pin 155. The limiting pin 155 cooperates with the first slide groove 154, and the limiting pin 155 can move along the first slide groove 154. Of course, a first slide groove 154 extending in the sliding direction can also be provided on the table assembly 110, and a limit pin 155 can be provided on the connecting frame 120, which is not limited here.

[0042] Specifically, in this embodiment, the limiting pin 155 is connected to the connecting frame 120 or the table assembly 110 via the fixed bracket 156. When the first slide groove 154 is provided on the connecting frame 120, the fixed bracket 156 is connected to the table assembly 110; the limiting pin 155 passes through the fixed bracket 156 and the first slide groove 154 in sequence, and slides in cooperation with the first slide groove 154; the fixed bracket 156 achieves a sliding connection with the connecting frame 120 through the cooperation of the limiting pin 155 and the first slide groove 154. The above-mentioned sliding guide mechanism 150 simplifies the structure and reduces manufacturing costs; it also has good spatial adaptability, and the shape, length, and position of the slide groove can be flexibly designed and optimized according to the specific structure of the connecting frame 120, which can better adapt to the complex installation space 111 constraints of the seat back. Alternatively, the limiting pin 155 can be fixedly provided on the connecting frame 120, and the fixed bracket 156 can be provided with a first slide groove 154 extending in the sliding direction. Alternatively, a first slide groove 154 can be provided on the tabletop assembly 110, a fixed bracket 156 can be connected to a connecting frame 120, and a limiting pin 155 can be sequentially passed through the fixed bracket 156 and the first slide groove 154 and slidably engaged with the first slide groove 154; the fixed bracket 156 can achieve a sliding connection with the tabletop assembly 110 through the engagement of the limiting pin 155 and the first slide groove 154.

[0043] In addition, the sliding guide mechanism 150 can also adopt other linear motion mechanisms, which are not limited here. For example, the sliding guide mechanism 150 can also adopt a gear and rack structure, that is, the slide rail 151 and slider 152 structure is replaced with a gear and rack, and the extension and retraction are achieved by rotating the handle or button. The gear structure naturally has a self-locking ability and can also prevent accidental retraction.

[0044] Please see Figures 1-17In this embodiment, the flipping mechanism 140 includes a first connecting rod 141 and a second connecting rod 142. One end of the first connecting rod 141 is hinged to the fixed base 130, and the other end of the first connecting rod 141 is hinged to the connecting frame 120. One end of the second connecting rod 142 is hinged to the fixed base 130, and the other end of the second connecting rod 142 is hinged to the connecting frame 120. In order to avoid the movement of the flipping mechanism 140, the table assembly 110 is provided with a clearance groove 112 for avoiding the first connecting rod 141 and / or the second connecting rod 142.

[0045] To ensure the stability and reliability of the folding and retraction of the car seat table 100, two clearance grooves 112 are provided at intervals along the length of the upper housing 113 in this embodiment. The two clearance grooves 112 are located near the edge of the upper housing 113. Correspondingly, there are also two flipping mechanisms 140 and two sliding guide mechanisms 150 in this embodiment, which are arranged one-to-one with the two clearance grooves 112. Arranging the clearance grooves 112 near the two side edges also leaves a complete and continuous unobstructed space in the central area of ​​the table assembly 110, improving space utilization.

[0046] Optionally, in this embodiment, the connecting frame 120 includes two opposing first connecting plates 121, with a first connecting rod 141 and a second connecting rod 142 disposed between the two first connecting plates 121. The first connecting rod 141 is hinged to the first connecting plate 121, and the second connecting rod 142 is hinged to the first connecting plate 121. A clearance groove 112 is formed between the two first connecting plates 121. Alternatively, the connecting frame 120 may also include a second connecting plate 122, with the two first connecting plates 121 connected via the second connecting plate 122 to form a U-shaped structure. To avoid the movement of the flipping mechanism 140, a clearance groove 1221 is provided on the second connecting plate 122 of the connecting frame 120 in this embodiment. Of course, the height of the first connecting plate 121 can also be increased so that the flipping mechanism 140 does not touch the second connecting plate 122 during movement, thus eliminating the need for the clearance groove 1221.

[0047] Please continue reading. Figures 1-17In this embodiment, a slider 152 is fixedly connected to the bottom end of the connecting frame 120 away from the flipping mechanism 140. The table assembly 110 is also provided with a slide rail 151, which slides in cooperation with the slider 152, so that the slide rail 151 can move relative to the slider 152 in the sliding direction, thereby driving the table assembly 110 to extend or retract in the sliding direction. At least a portion of the two first connecting plates 121 is disposed within the slide rail 151. Specifically, in this embodiment, the slider 152 is fixedly connected to the ends of the two first connecting plates 121 away from the flipping mechanism 140, and the sliders 152 at the ends of the first connecting plates 121 are connected to a single slide rail 151, which constitutes two support points. Compared with single-point support, this design can effectively prevent the table from tilting, warping, or wobbling after extension. The force on the table can be transmitted to the two first connecting plates 121 through the flipping mechanism 140, and then distributed to the slide rail 151 through the two sliders 152. This force distribution is more reasonable, avoiding stress concentration and making the structure more robust and with better load-bearing capacity. Of course, the slider 152 can also be connected to the second connecting plate 122.

[0048] To further increase the structural strength of the sliding guide mechanism 150 and the connecting frame 120, thereby improving the stability and reliability of the overall structure, in this embodiment, the slider 152 is embedded between the two first connecting plates 121, and / or the connecting frame 120 is embedded in the slide rail 151. Specifically, in this embodiment, the connecting frame 120 includes two parallel and spaced-apart first connecting plates 121, both of which are connected to the table assembly 110. The slider 152 is embedded between the two first connecting plates 121, and the slide rail 151 is sleeved on the outside of the two first connecting plates 121. Of course, the slide rail 151 can also be disposed between the two first connecting plates 121, which is not limited here.

[0049] Optionally, in this embodiment, there are two of each of the first link 141, the second link 142, and the fixing seat 130, with each set of the first link 141, the second link 142, and the fixing seat 130 corresponding to each other. Designing the links as a four-bar linkage allows the links to be concealed below the tabletop of the table assembly 110 during use, ensuring full utilization of the tabletop. Furthermore, the four-bar linkage improves the stability, smoothness, and structural strength of the overall structure during folding movements.

[0050] Of course, the flipping mechanism 140 can also be designed as a single-link mechanism or other structural forms of flipping mechanism 140, as long as it can achieve the folding of the tabletop assembly towards or away from the seat back 200, which is not limited here. When the flipping mechanism 140 is a single-link mechanism, one end of the single link is fixedly connected to the connecting frame 120, and the other end of the single link is rotatably connected to the fixed base 130. The single link can rotate relative to the fixed base 130, thereby driving the tabletop assembly 110 to flip as a whole through the connecting frame 120, so as to realize the switching of the tabletop assembly 110 between the unfolded state and the folded state.

[0051] Furthermore, to improve the overall aesthetics and practicality of the car seat table 100, the car seat table 100 in this embodiment also includes a first cover 161. The first cover 161 is fixedly disposed on the top of the two first connecting plates 121, and the first cover 161 is configured to cover at least a portion of the clearance groove 112 after the table assembly 110 is extended. As a physical barrier, the first cover 161 effectively isolates the risk of the user's fingers, skin, or clothing being caught in moving parts; it also covers hinge points, pins, and other parts that may have burrs or sharp edges, preventing the user from being scratched, and greatly enhancing the safety performance of the car seat table 100. The first cover 161 completely hides the complex and seemingly messy mechanical structure, allowing the table to form a complete and aesthetically pleasing desktop when unfolded, thus improving the aesthetics of the car seat table 100. In addition, the desktop is a major area for spilled liquids and food crumbs. The first cover 161 effectively prevents contaminants from entering the clearance groove 112, avoiding the accumulation of dust, sugar, oil stains, etc. at the connecting rod hinge, which could cause the mechanism to jam, make abnormal noises, or corrode, thus ensuring the long-term smooth operation of the mechanism and extending its service life.

[0052] To ensure that the entire flipping mechanism 140 (first link 141 and second link 142) can be completely hidden under the tabletop and not seen from any angle after the tabletop is fully unfolded, in this embodiment, the distance between the hinge point of the first link 141 and the connecting frame 120 and the fixed seat 130 is greater than the distance between the hinge point of the second link 142 and the connecting frame 120 and the fixed seat 130. This ensures that, when the tabletop assembly 110 is unfolded, the upper surface 1411 of the portion of the first link 141 and the second link 142 extending into the installation space 111 is not higher than the upper surface of the tabletop assembly 110. Since the fixing point of the first link 141 is farther from the fixed seat 130, while the fixing point of the second link 142 is closer to the fixed seat 130, this asymmetrical layout allows the two links to be almost parallel and close to the same horizontal plane when the linkage system is unfolded and locked in the horizontal position. This plane is lower than the lower surface of the tabletop, improving the overall aesthetics of the car seat tabletop 100.

[0053] Please continue reading. Figures 24-27 and combined Figure 17 In this embodiment, the car seat table 100 also includes a second cover 162, and the connecting frame 120 has a second sliding groove 1212. In this embodiment, the first connecting plate 121 has a second sliding groove 1212. One end of the second cover 162 is hinged to the first connecting rod 141, and the other end of the second cover 162 is slidably engaged with the second sliding groove 1212. The second cover 162 is configured to cover at least a portion of the clearance groove 112 when the table assembly 110 is in the unfolded state. That is, the second cover 162 can move within the second sliding groove 1212 as the flipping mechanism 140 rotates, so that the second cover 162 can rotate and extend with the rotation of the flipping mechanism 140, always covering a portion of the structure of the flipping mechanism 140 located within the clearance groove 112.

[0054] Optionally, the other end of the second cover 162 is provided with a sliding shaft, which slides in the second slide groove 1212. Optionally, one end of the second cover 162 is provided with a pivot hole, and a pivot is provided in the pivot hole. The second cover 162 is hinged to the flipping mechanism 140 through the pivot.

[0055] In this embodiment, the tabletop of the car seat includes both a first cover 161 and a second cover 162. The first cover 161 and the second cover 162 are arranged sequentially along the sliding direction and are both connected to the connecting frame 120. The second cover 162 is closer to the first connecting rod 141 than the first cover 161. Of course, only the first cover 161 or only the second cover 162 may be provided, and this is not limited here.

[0056] For easy and quick installation and removal of the first cover 161, please refer to Figure 33 and combined Figure 29 and Figure 30 In this embodiment, the first cover 161 is snapped into the tabletop assembly 110. Specifically, the connecting frame 120 has multiple slots 1211, and the first cover 161 has multiple snap-fit ​​protrusions 1611 that mate with the slots 1211. The multiple slots 1211 and the multiple snap-fit ​​protrusions 1611 are arranged in a one-to-one correspondence. Of course, multiple snap-fit ​​protrusions 1611 can also be provided on the connecting frame 120, and multiple slots 1211 that mate with the snap-fit ​​protrusions 1611 can be provided on the first cover 161; this is not limited here. In addition, the first cover 161 can also be connected to the tabletop assembly 110 using threaded fasteners, or it can be connected to the tabletop assembly 110 using other connection methods such as plug-in or welding; this is not limited here. In order to prevent the first cover 161 from affecting the movement of the second cover 162 following the flipping mechanism 140, the end of the first cover 161 does not exceed the end of the second slide groove 1212 that is away from the flipping mechanism 140.

[0057] When the tabletop assembly is folded down to be close to the seat back 200, the first link 141 drives the second cover 162 to move, so that the sliding shaft at the other end of the second cover 162 slides along the second sliding groove 1212 until the second cover 162 is basically parallel to the surface of the table 100 of the car seat and is embedded in the table assembly 110.

[0058] To make efficient use of space, a damping assembly 143 is provided at the hinge point between the first link 141 and the fixed base 130 in this embodiment; and / or at the hinge point between the second link 142 and the fixed base 130. The damping assembly 143 may be provided only at the hinge point between the first link 141 and the fixed base 130, or only at the hinge point between the second link 142 and the fixed base 130; or the damping assembly 143 may be provided at both the hinge points between the first link 141 and the second link 142 and the fixed base 130. The damping assembly 143 can effectively suppress the movement speed of the table assembly 110 during the flipping, unfolding, and folding processes, ensuring its uniform, smooth, and controlled movement. By setting up the damping assembly 143, the phenomenon of the tabletop suddenly opening or closing rapidly due to its own weight or improper force applied by the user can be eliminated, which greatly reduces the risk of pinching the user's fingers or hitting the occupant's body, and significantly improves the safety performance of the product.

[0059] Please see Figure 34 In this embodiment, the connecting frame 120 covers the table frame 115, and the flipping mechanism 140 is disposed on both sides of the connecting frame 120 perpendicular to the sliding direction. The connecting frame 120 is connected to the upper housing 113. The connecting frame 120 can slide relative to the table frame 115 so that when the table 100 of the car seat is in the extended state, it together with the upper housing 113 forms a usable table surface. Specifically, in this embodiment, the connecting frame 120 is designed as a panel structure of the same size as the table frame 115. The slider 152 is fixedly connected to the table frame 115, and the slide rail 151 is slidably engaged with the slider 152. The slide rail 151 is connected to the connecting frame 120, and the connecting frame 120 covers the slide rail 151. The slide rail 151 can slide relative to the slider 152 to drive the connecting frame 120 to slide relative to the table frame 115, thereby realizing the extension or retraction of the connecting frame 120 and the upper housing 113, so that the connecting frame 120 and the upper housing 113 together form a usable table surface.

[0060] In detail, the connecting frame 120 in this embodiment includes two spaced-apart side plates and a top plate connecting the two side plates. There are two flipping mechanisms 140, each connected to one of the two side plates. A slide rail 151 is connected to the top plate, and a slider 152 is embedded in the slide rail 151. The flipping mechanism 140 can be either a four-flipping mechanism or a single flipping mechanism. When the flipping mechanism 140 is a single flipping mechanism, one end of the single connecting rod is fixedly connected to the side plate of the connecting frame 120, and the other end is rotatably connected to the fixed base 130. The single connecting rod can rotate relative to the fixed base 130, thereby causing the tabletop assembly 110 to flip as a whole through the connecting frame 120, thus achieving the switching between the unfolded and folded states of the tabletop assembly 110. When the flipping mechanism 140 is a four-flipping mechanism 140, one end of the first connecting rod 141 is hinged to the side plate, and the other end of the first connecting rod 141 is hinged to the fixed base 130; one end of the second connecting rod 142 is hinged to the fixed base 130, and the other end of the second connecting rod 142 is hinged to the connecting frame 120. The first connecting rod 141 and the second connecting rod 142 together drive the connecting frame 120 and the table assembly 110 to flip. Of course, the flipping mechanism 140 can also be connected to the top plate, and the slide rail 151 can be connected to the side plate; this is not limited here.

[0061] In summary, the car seat table 100 includes a table assembly 110, a connecting frame 120, a fixed seat 130, and a flipping mechanism 140. The table assembly 110 has an installation space 111 inside. The connecting frame 120 is disposed within the installation space 111 and is slidably connected to the table assembly 110, allowing the table assembly 110 to extend or retract along the sliding direction. The fixed seat 130 is used to connect to the seat back 200. One end of the flipping mechanism 140 is rotatably connected to the fixed seat 130, and the other end is connected to the connecting frame 120. The flipping mechanism 140 can rotate relative to the fixed seat 130, thereby driving the table assembly 110 to flip as a whole through the connecting frame 120, thus achieving the switching between the unfolded and folded states of the table assembly 110. Through the sliding connection, the table assembly 110 can flexibly adjust its effective usable area; it can extend when needed to provide a larger usable desktop; and it can retract when not needed to save space and avoid obstructing passenger movement. Furthermore, the aforementioned structural design allows the force to be transmitted through the table assembly 110 to the connecting frame 120, and then directly to the fixed seat 130 connected to the seat back 200 via the flipping mechanism 140, forming a stable multi-link support structure. Compared to a table that extends outwards like a drawer to form a cantilever beam, this design improves load-bearing capacity and stability, effectively reducing swaying. In addition, when the car seat table 100 is folded, the table assembly 110 can be tightly folded and fitted against the back of the seat back 200, maintaining a flat and aesthetically pleasing surface. Moreover, the car seat table 100 is easy to operate; the operator can unfold, extend, and fold it with one hand, making it convenient to use.
