Description

Technical Field

[0001] This invention belongs to the field of seat bottom tray tables, specifically relating to a universal tray table structure integrated into the bottom of the rear seat. Background Technology

[0002] With the continuous development of the automotive industry and the deepening trend of consumption upgrading, users' requirements for driving and riding experience have gradually evolved from basic "safety and comfort" to "intelligentization, multi-functionality, and personalization". Especially in the mid-to-high-end passenger car market, the premium experience of rear passengers has become one of the important dimensions reflecting the value of the whole vehicle.

[0003] Most of the adjustable tray table structures currently available on the market are used in rear armrests. For example, Chinese Patent Publication No. CN119590303A discloses a rear armrest tray table installation structure and a car seat, including an armrest assembly and a tray table set on top of the armrest assembly. A lifting mechanism is provided between the tray table and the armrest assembly. When the tray table is unfolded for use, the lifting mechanism can move the tray table upward relative to the armrest assembly. This structure, through the lifting mechanism, can raise the unfolded height of the tray table, thereby ensuring the passenger's riding comfort.

[0004] However, existing car seat rear armrests often have cup holders, which makes it difficult to fit a small table inside the rear armrest. In the context of the trend towards multi-functional car seats, the existing small table structure can no longer be installed in other locations (such as the bottom of the seat). In other words, the existing small table structure needs to be significantly improved to allow it to be easily flipped from other positions to the user's desired location. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a universal small table structure integrated into the bottom of the rear seat, which is simple in structure, has good stability, does not occupy passenger space, and improves the smoothness and accuracy of the flip-out action.

[0006] The objective of this invention can be achieved by addressing the following technical problem: proposing a universal small table structure integrated into the bottom of the rear seat, comprising: a base installed at the bottom of the seat, wherein a track groove is provided on the base;

[0007] A transmission assembly and a lifting assembly are movably disposed within the base, used to drive the lifting assembly to extend outside the base; the lifting assembly is connected to the output end of the transmission assembly and is movably engaged in the track groove, so that when the lifting assembly moves to the end of the track groove, it folds relative to the output end to a vertical position;

[0008] A rotating assembly and a tabletop assembly, the rotating assembly being connected to the lifting assembly for rotating the tabletop assembly above the lifting assembly; the tabletop assembly being movably connected to the rotating assembly and having a small tabletop body that can be switched between a retracted state and a usable state;

[0009] When the transmission assembly drives the lifting assembly to extend beyond the seat along the length of the base, the lifting assembly can fold relative to the transmission assembly to the front end of the seat due to the track groove, so that the rotating assembly can cooperate with the table assembly to switch the small table body from the retracted state to the usable state.

[0010] In the aforementioned omnidirectional small table structure integrated into the bottom of the rear seat, the trajectory groove includes:

[0011] The first guide groove has a guide portion and a traction portion. The guide portion is arranged along the length direction of the base, and the traction portion is arranged along the height direction of the base and is connected to the end of the guide portion near the outer side of the seat. The lifting assembly is connected to a first engaging block, which can reciprocate within the guide portion and the traction portion.

[0012] The second guide groove is arranged parallel to the first guide groove and is not connected to it. The output end of the transmission component is connected to a second engaging block, which is movably connected in the second guide groove.

[0013] In the aforementioned universal table structure integrated into the bottom of the rear seat, the length of the second guide groove is greater than the length of the guide part, and the end of the second guide groove near the outer side of the seat is in the same vertical direction as the traction part.

[0014] In the aforementioned universal table structure integrated into the bottom of the rear seat, both the first locking block and the second locking block include an anti-detachment part and a locking part. The anti-detachment part and the locking part are coaxially arranged. When the locking part extends into the first guide groove or the second guide groove, the anti-detachment part can move and abut against the inner wall of the base.

[0015] In the aforementioned universal table structure integrated into the bottom of the rear seat, the transmission component includes:

[0016] The mounting base has a storage cavity along its length, and the mounting base is disposed in the storage cavity;

[0017] A lead screw and a drive unit, wherein one end of the lead screw is disposed on the mounting base and the other end is connected to the drive end of the drive unit to drive the lead screw to rotate within the receiving cavity;

[0018] A movable block is movably connected to the lead screw, the lifting assembly is movably hinged to the movable block, and the second engaging block is connected to the two side walls of the movable block.

[0019] In the aforementioned universal small table structure integrated into the bottom of the rear seat, the lifting component includes a rotating arm and a connecting pin. An extension block is formed on the side of the rotating arm facing the seat, and the anti-detachment part is connected to the two side walls at the end of the extension block. A connecting part is formed on the moving block, and the connecting pin passes through the rotating arm and the connecting part, so that the rotating arm can be folded relative to the moving block and set at a right angle to it.

[0020] In the aforementioned universal table structure integrated into the bottom of the rear seat, the rotating assembly includes a rotating motor and a rotating plate. The rotating motor is installed at the end of the rotating arm away from the moving block. The rotating plate is movably attached to the rotating arm, and one end of the rotating plate is connected to the output shaft of the rotating motor, while the other end is movably hinged to the table assembly.

[0021] In the aforementioned universal table structure integrated into the bottom of the rear seat, a stepped groove is also formed on the rotating arm, which provides clearance space for the rotating plate and the table assembly to retract to the side wall of the rotating arm.

[0022] In the aforementioned omnidirectional small table structure integrated into the bottom of the rear seat, the table assembly includes:

[0023] A support plate is movably connected to the end of the rotating plate. A limiting surface is formed on the rotating plate. When the support plate is folded relative to the rotating plate, it is movably pressed against the limiting surface to place the small table body in the use state.

[0024] The damper has an installation groove in the support plate, and the damper is disposed in the installation groove. The small table body is connected to the rotation shaft of the damper.

[0025] In the aforementioned universal table structure integrated into the bottom of the rear seat, the table body includes a first table and a second table that are hinged to each other, and the first table and the second table can freely switch between an overlapping position and an unfolded position.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] (1) The present invention provides a universal small table structure integrated into the bottom of the rear seat. By setting a guide structure with a specific trajectory groove in the base, and cooperating with the linkage of the transmission component and the lifting component, the small table achieves a compound movement of "horizontal extension - front end folding - vertical positioning - unfolding for use". This ensures that the small table can be smoothly unfolded from the hidden position under the seat to a suitable height in front of the seat. The operation is simple and the process is smooth. At the same time, the whole structure makes full use of the idle space under the seat to achieve "hidden integration". It expands the functional configuration without affecting the riding comfort. It is especially suitable for the rear seat layout of passenger cars with compact space and significantly improves the user experience.

[0028] (2) The length of the second guide groove is greater than the length of the traction part. This staggered length design ensures that the lifting component can obtain sufficient torque to complete the flipping action when it reaches the trajectory inflection point, avoiding incomplete flipping due to premature disengagement; and the end of the second guide groove is on the same vertical line as the guide part, which facilitates the cooperation with the locking block to form a locking force on the rotating arm in the vertical direction, ensuring the stability of the user when using the small table structure.

[0029] (3) A stepped groove is provided on the rotating arm to provide clearance for the rotating plate and table assembly when they are folded up, allowing them to fit snugly against the side wall of the rotating arm. This greatly reduces the overall volume of the structure. This design effectively achieves a compact layout of the multi-level folding mechanism, allowing the entire small table system to be completely hidden under the seat when not in use, without affecting the aesthetics of the vehicle interior or the passenger space. This aligns with the modern automotive interior design trend towards lightweighting, miniaturization, and concealed integration. Attached Figure Description

[0042] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0043] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0044] like Figures 1 to 6 As shown, the present invention provides a universal small table structure integrated into the bottom of the rear seat, including a base 1, a transmission component 2, a lifting component 3, a rotating component 4, and a table component 5.

[0045] The base 1 is installed at the bottom of the seat, and a track groove 10 is formed on the base 1. The transmission assembly 2 and the lifting assembly 3 are movably disposed within the base 1, for driving the lifting assembly 3 to extend outside the base 1. The lifting assembly 3 is connected to the output end of the transmission assembly 2 and is movably engaged in the track groove 10, so that when the lifting assembly 3 moves to the end of the track groove 10, it folds relative to the output end to a vertical position. The rotating assembly 4 is connected to the lifting assembly 3, for rotating the table assembly 5 above the lifting assembly 3. The table assembly 5 is movably connected to the rotating assembly 4 and has a retractable state (see reference). Figure 1 and Figure 2 The structure shown is the one placed vertically) and its usage state (see reference). Figure 3The structure shown is a small table body 50 that can switch between horizontal and horizontal orientations. When the transmission component 2 drives the lifting component 3 to extend out of the seat along the length of the base 1, the lifting component can be folded relative to the transmission component 2 to the front end of the seat due to the track groove 10, so that the rotating component can cooperate with the table assembly 5 to switch the small table body 50 from the retracted state to the use state.

[0046] like Figure 1 As shown, in this embodiment, the base 1 is preferably installed at the bottom of the middle seat in the rear row of the car, and at least one set of the universal small table structure is provided in the base 1 (two sets are used in this embodiment to achieve...). Figure 3 (The shown state meets the usage needs of the left and right seat users) When the omnidirectional small table structure is fully retracted to Figure 1 When the small table body 50 is inside the base 1, it is in a retracted state and pressed against the rotating component 4. At the same time, the rotating component 4 is also pressed against the side wall of the lifting component 3, so that the entire structure is completely hidden under the seat and does not protrude from the seat outline. When the user issues a control signal (such as a button or voice command), the lifting component 3 can be driven by the transmission component 2 to extend horizontally outward along the length of the base 1 (i.e., in...). Figure 1 (From the base 1, it moves horizontally to the left). During this process, the entire structure maintains a horizontal posture and gradually extends into the space below the front of the seat, as shown below. Figures 1 to 3 As shown, when the lifting component 3 slides to the end of the track groove 10, the track groove 10 forces the lifting component 3 to rotate relative to the output end of the transmission component 2 (the direction of rotation is towards one side of the seat). That is, the lifting component 3 folds upward around its hinge point with the transmission component 2, gradually rotating from a horizontal posture to a near-vertical posture. This folding action lifts the table assembly 5 from under the seat to the usable height at the front of the seat, completing the spatial transformation from "hidden to revealed". After the lifting component 3 is folded into place, the rotating component 4 is activated to drive the table assembly 5 to rotate 180 degrees, so that the table assembly 5 is above the lifting component 3 (at this time, the table assembly 5 is still placed in a vertical posture and is in a retracted state, see reference). Figure 2This allows users to adjust the position of the small table assembly 5 from its retracted state to its active state, enabling it to be positioned directly in front of or to the side of the rear passengers. This achieves omnidirectional positioning of the small table, adapting to different seating postures and usage needs. Therefore, this invention, through the coordinated structure of the base 1, transmission assembly 2, lifting assembly 3, rotating assembly 4, and table assembly 5 integrated at the bottom of the seat, achieves a fully automated operation process where the small table automatically extends, lifts, flips, and unfolds from the bottom of the seat. This structure cleverly utilizes the trajectory groove 10 to guide the movement path of the lifting assembly 3, automatically triggering a folding action at the end of the extension stroke. Combined with the rotating assembly 4 and table assembly 5, this allows the small table body 50 to smoothly reach the front of the seat and adjust its posture. The overall structure is compact and the movements are fluid, significantly improving the convenience and comfort of rear passengers using the small table. Simultaneously, the entire mechanism is hidden under the seat, not occupying interior space, significantly improving interior space utilization and aesthetics, making it suitable for the intelligent configuration needs of high-end passenger vehicles' rear seats.

[0047] The track groove 10 includes: a first guide groove 100, which has a guide portion 100a and a traction portion 100b. The guide portion 100a is arranged along the length direction of the base 1, and the traction portion 100b is arranged along the height direction of the base 1 and is connected to the end of the guide portion 100a near the outer side of the seat. A first engaging block 30 is connected to the lifting assembly 3. The first engaging block 30 can reciprocate within the guide portion 100a and the traction portion 100b. A second guide groove 101 is arranged parallel to the first guide groove 100 and is not connected to it. A second engaging block 20 is connected to the output end of the transmission assembly 2. The second engaging block 20 is movably connected within the second guide groove 101.

[0048] like Figures 1 to 3 As shown, by setting a first guide groove 100 composed of a guide part 100a and a traction part 100b, and a second guide groove 101 parallel to but independently arranged therewith, the separate path motion control of the lifting component 3 and the output end of the transmission component 2 is realized; that is, during the process of driving the lifting component 3 to move at the output end of the transmission component 2, the first locking block 30 slides in advance in the guide part 100a to ensure that the lifting component 3, the rotating component 4 and the table component 5 can all extend smoothly to the outside of the base 1. Preferably, in this embodiment, the connection between the guide part 100a and the traction part 100b adopts an arc transition. Therefore, as the output end of the transmission component 2 continues to apply driving force, the first locking block 30 will slide from the end of the guide part 100a into the traction part 100b. Since the line connecting the first locking block 30 and the second locking block 20 is inclined at this time (see reference). Figure 2 This also causes the lifting component 3 to gradually fold from a horizontal position as it almost fully extends beyond the base 1. Figure 3The vertical posture shown (the folding direction is towards the seat) is such that during this process, the second locking block 20 only moves in a straight line in the second guide groove 101 to transmit driving force and prevent the lifting component 3 from being misaligned and causing jamming. This dual-groove separation design avoids motion interference, improves transmission stability and structural reliability, effectively prevents jamming or misalignment, and enhances the smoothness and durability of the overall mechanism operation.

[0049] The length of the second guide groove 101 is greater than the length of the guide portion 100a, and the end of the second guide groove 101 near the outer side of the seat is in the same vertical direction as the traction portion 100b.

[0050] like Figure 2 and Figure 3 As shown, with the activation of the transmission assembly 2, the first locking block 30 and the second locking block 20 can be pushed to slide within the guide portion 100a and the second guide groove 101, respectively. Since the traction portion 100b is perpendicular to the guide portion 100a, it forces the front end of the lifting assembly 3 to be lifted. Figure 1 As shown at the leftmost end, the second locking block 20 continues to slide forward in the second guide groove 101 (because the second guide groove 101 is longer and has not yet reached its end), the rear end of the lifting component 3 (the hinge point with the transmission component 2) continues to move forward, and is thus pulled upward by the front end to form a flipping motion around the hinge point of the lifting component 3 and the transmission component 2, until the lifting component 3 gradually flips from horizontal to a near-vertical position; therefore, in this embodiment, the length of the second guide groove 101 is greater than the length of the traction part 100b, and its outer end is on the same vertical line as the guide part 100a, which means that the output end of the transmission component 2 can be lifted. After the vertical folding is completed, component 3 still maintains its supporting and guiding functions. In addition, thanks to the cooperation of the guide part 100a and the traction part 100b, the second locking block 20 can continue to move after the first locking block 30 enters the traction part 100b. The transmission connection is not locked, allowing the lifting component 3 to make fine adjustments and attitude transitions during the folding process, avoiding rigid jamming. This design extends the effective transmission range in a limited space, making the lifting process more stable and controllable. In particular, it can still provide continuous power support at the folding turning point, avoiding action failure or vibration noise due to power interruption, thus improving the user experience and system response accuracy.

[0051] The first locking block 30 and the second locking block 20 both include an anti-detachment part 600 and a locking part 601. The anti-detachment part 600 and the locking part 601 are coaxially arranged. When the locking part 601 extends into the first guide groove 100 or the second guide groove 101, the anti-detachment part 600 can move and abut against the inner wall of the base 1.

[0052] like Figure 3 and Figure 4As shown, in this embodiment, the engaging portion 601 slides within the first guide groove 100 and the second guide groove 101. Simultaneously, the anti-detachment portion 600 remains in contact with the inner wall of the base 1, forming a stable support. This effectively prevents the engaging block from axially dislodging due to vibration or lateral force, thereby ensuring the smoothness and stability of the engaging portion 601 during sliding. This structure effectively prevents the engaging block from detaching from the guide groove under vibration, greatly enhancing the connection strength and safety of the moving pair, improving the overall structure's impact resistance and long-term stability, and meeting the high reliability standards for automotive components. Preferably, in this embodiment, a low-friction material (such as a PTFE coating or nylon gasket) can be provided between the anti-detachment portion 600 and the inner wall of the base 1 to ensure improved sliding smoothness.

[0053] The transmission assembly 2 includes: a mounting base 21, a base 1 having a receiving cavity 11 along its length, and the mounting base 21 being disposed within the receiving cavity 11; a lead screw 22 and a driving member 23, one end of the lead screw 22 being disposed on the mounting base 21 and the other end being connected to the driving end of the driving member 23 to drive the lead screw 22 to rotate within the receiving cavity 11; a moving block 24 being movably connected to the lead screw 22, a lifting assembly 3 being movably hinged to the moving block 24, and a second engaging block 20 being connected to the two side walls of the moving block 24.

[0054] like Figures 3 to 5 As shown, this embodiment uses a transmission assembly 2 consisting of a lead screw 22, a drive component 23 (such as a stepper motor or servo motor), and a moving block 24. The lead screw 22 transmission itself has the advantages of high transmission accuracy, good self-locking performance, and low noise. By installing the lead screw 22 on the mounting base 21 in the storage cavity 11, and using the threaded engagement between the moving block 24 and the lead screw 22, the lifting assembly 3 connected by the hinge can be driven to achieve linear reciprocating motion. The structure is compact and easy to integrate. At the same time, this transmission method has a fast response and precise control, making it suitable for automated control. When combined with the vehicle power system, it can realize the one-button unfolding / retracting function, enhancing the intelligent experience.

[0055] The lifting assembly 3 includes a rotating arm 31 and a connecting pin 32. An extension block 310 is formed on the side of the rotating arm 31 facing the seat. An anti-slip part 600 is connected to the two side walls at the end of the extension block 310. A connecting part 240 is formed on the moving block 24. The connecting pin 32 passes through the rotating arm 31 and the connecting part 240, so that the rotating arm 31 can be folded relative to the moving block 24 and set at a right angle to it.

[0056] like Figures 3 to 5As shown, in the folded state, the rotating arm 31 in this embodiment is horizontal. Its front end is used to connect to the rotating component 4, and its rear connecting pin 32 is hinged to the connecting part 240 on the moving block 24, thus forming a foldable movable connection structure. Specifically, since there is a certain distance between the extension block 310 and the moving block 24, and the extension block 310 is connected to the first locking block 30, during the movement of the second locking block 20 in the second guide groove 101, the rotating arm 31 is forced to rotate around the connecting pin 32 due to the trajectory constraint, and finally forms a right angle with the moving block 24, thus achieving automatic uprighting. It is worth noting that since the position between the extension block 310 and the moving block 24 remains unchanged, as the rotating arm 31 gradually approaches the vertical position, the first locking block 30 will gradually descend from the top of the traction part 100b to a certain height (but will not detach from the traction part 100b) to match the height difference between the extension block 310 and the moving block 24. At the same time, the first locking block 30 and the second locking block 20 are respectively engaged with the ends of the traction part 100b and the second guide groove 101, thereby forming a certain locking force on the vertical rotating arm 31, ensuring that the user will not experience shaking or even mis-locking when using the small table body 50.

[0057] The rotating assembly 4 includes a rotating motor 40 and a rotating plate 41. The rotating motor 40 is installed at the end of the rotating arm 31 away from the moving block 24. The rotating plate 41 is movably attached to the rotating arm 31, and one end of the rotating plate 41 is connected to the output shaft of the rotating motor 40, while the other end is movably hinged to the table assembly 5.

[0058] like Figures 3 to 6 As shown, as the first locking block 30 slides from the guide portion 100a into the traction portion 100b, the rotating arm 31 gradually tilts and adjusts towards a vertical alignment position, as... Figure 2 The structure shown has the rotating arm 31 positioned at a 45-degree angle. In this embodiment, the rotary motor 40 can control the rotating plate 41 to rotate from a position close to the side wall of the rotating arm 31 to above the rotating arm 31, provided that the table assembly 5 does not interfere with the position of any component (base 1). Figure 3 The rotating plate 41 and the rotating arm 31 are in the same vertical direction, allowing the table assembly 5 to be flexibly rotated to the optimal usage position in front of the passenger, adapting to passengers of different sizes or usage scenarios (such as left / right seating). This electric rotation method is easy to operate, accurate in positioning, and significantly improves ergonomics and user comfort. It is worth noting that the rotation of the rotating plate 41 driven by the rotating motor 40 can be synchronized with the rotation of the rotating arm 31. Figure 2 Fold to Figure 3The actions at the indicated positions are performed simultaneously, effectively shortening the time required for the entire omnidirectional small table structure to unfold and be used, and preventing users from experiencing a negative impact on their overall user experience due to long waiting times.

[0059] A stepped groove 311 is also formed on the rotating arm 31, which provides clearance space for the rotating plate 41 and the table assembly 5 to retract to the side wall of the rotating arm 31.

[0060] like Figure 5 As shown, this embodiment also provides a stepped groove 311 on the rotating arm 31 to provide clearance space for the rotating plate 41 and the table assembly 5 in the retracted state. That is, when the table assembly 5 is retracted and attached to the side of the rotating arm 31, it will not protrude outside the overall structure, thereby achieving complete embedded storage. This design optimizes the internal layout, reduces the overall volume of the mechanism, ensures that the small table is completely hidden under the seat, does not affect the neatness of the seat appearance and the safety of riding, and also avoids the risk of scratches from foreign objects.

[0061] The tabletop assembly 5 includes: a support plate 51, which is movably connected to the end of the rotating plate 41, a limiting surface 410 is formed on the rotating plate 41, and the support plate 51 is movably pressed against the limiting surface 410 when it is folded relative to the rotating plate 41, so as to put the small tabletop body 50 into the use state; and a damper 52, in which the support plate 51 has an installation groove 510, the damper 52 is disposed in the installation groove 510, and the small tabletop body 50 is connected to the rotating shaft of the damper 52.

[0062] like Figures 3 to 5 As shown, the aforementioned rotary motor 40 rotates the rotating plate 41 to above the rotating arm 31 (e.g., Figure 3 As shown), at this time, the support plate 51 can be folded relative to the rotating plate 41 in advance (the folding direction is along the width direction of the rotating plate 41, i.e. Figure 3 (as shown in the horizontal direction), during this process, the support plate 51 abuts against the rotating plate 41 through the limiting surface 410 to form a stable support structure, preventing the table from shaking or sinking and ensuring sufficient load-bearing capacity; at the same time, this embodiment also provides a damper 52 in the support plate 51, so that by connecting the small table body 50 to the rotating shaft, the small table body 50 can move relative to the support plate 51 along the horizontal direction. Figure 3 The horizontal position is adjusted to ensure that it is accurately positioned as required by the user. Therefore, the design of the damper 52 enables the small table body 50 to open and close slowly, hover at any angle, and operate without impact or noise. This improves the opening and closing feel, enhances the product's premium feel and safety, and is especially suitable for children's car environments.

[0063] The small table body 50 includes a first table 500 and a second table 501 that are hinged to each other. The first table 500 and the second table 501 can freely switch between an overlapping position and an unfolded use position.

[0064] like Figure 5 As shown, the small table body 50 in this embodiment is composed of a first table panel 500 and a second table panel 501 that are hinged together, and can be in an overlapping position (see reference). Figure 2 (Structure shown) and unfolded usage state (refer to) Figure 5 The folding design allows for free switching between different structures. This significantly increases the usable desktop area, meeting the needs of multiple users or multitasking (such as placing a laptop and a water cup). When not in use, it can be folded down to reduce its size for easy storage. The overall structure is flexible and practical, expanding the functional boundaries of the small tabletop and improving space utilization and user experience.

[0065] like Figures 1 to 6 As shown, in this embodiment, the omnidirectional small table structure is integrated into the base 1 and placed at the bottom of the middle rear seat. This not only saves space in the overall vehicle interior and effectively utilizes the unused space under the seat for a hidden arrangement, but also solves the problem that traditional armrests with cup holders cannot accommodate the space design of the small table structure. Furthermore, it integrates the linkage folding structure of the trajectory groove 10, the lifting component 3, and the transmission component 2, combined with the rotating component 4 and the switchable small table body 50, realizing a multi-degree-of-freedom integrated motion control structure for the small table to automatically extend from the bottom of the seat, fold and position itself, and unfold for use. Preferably, in this embodiment, an anti-detachment plate 12 can also be connected to the top of the base 1, such as... Figure 1 As shown, the anti-detachment plate 12 can confine the overall structure of the universal table within the base 1, preventing the misalignment of various components or even detachment from the base 1 due to vibration during vehicle operation, thereby improving the overall stability of the structure.
