Description

Technical Field

[0001] The invention belongs to the field of small table boards at the bottom of seats, and in particular relates to a universal small table board structure integrated at the bottom of a rear seat. Background Art

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

[0003] Regarding the small table adjustment structures currently on the market, most are used on the rear armrests. For example, the Chinese patent publication number is: CN119590303A, which mainly discloses a rear armrest small table installation structure and a car seat, including an armrest assembly and a small table arranged on the top of the armrest assembly. A lifting mechanism is provided between the small table and the armrest assembly. When the armrest small table is unfolded and used, the lifting mechanism can move the small table upward relative to the armrest assembly. The structure can raise the unfolded use height of the small table through the lifting mechanism, thereby ensuring the riding comfort of the occupants.

[0004] However, existing car seats often have cup holders on their rear armrests, which means that there is not enough space for the small table to be placed in the rear armrest. In the environment where car seats are becoming more multifunctional, the existing small table cannot be installed in other locations (such as the bottom of the seat). In other words, the existing small table needs to be significantly improved before it can be smoothly flipped from other positions to the user's desired usage position. Summary of the Invention

The output end of the transmission component is connected to a second engaging block, and the second engaging block is movably connected in the second guide groove.

[0008] In the above-mentioned universal small table structure integrated at the bottom of the rear seat, the length of the second guide groove is greater than the length of the guide portion, and the end of the second guide groove close to the outer side of the seat is in the same vertical direction as the traction portion.

[0009] In the above-mentioned universal small table structure integrated at the bottom of the rear seat, the first engaging block and the second engaging block both include an anti-slip portion and a engaging portion, and the anti-slip portion and the engaging portion are coaxially arranged. The anti-slip portion can be movably pressed against the inner wall of the base when the engaging portion extends into the first guide groove or the second guide groove.

[0010] In the above-mentioned universal small table structure integrated at the bottom of the rear seat, the transmission assembly includes: A mounting base, wherein the base is provided with a receiving cavity along its length, and the mounting base is arranged in the receiving cavity; A screw rod and a driving member, wherein one end of the screw rod is arranged on the mounting seat, and the other end is connected to the driving end of the driving member to drive the screw rod to rotate in the receiving cavity; The moving block is movably connected to the screw rod, the lifting assembly is movably hinged to the moving block, and the second engaging block is connected to the two side walls of the moving block.

[0011] In the above-mentioned universal small table structure integrated at the bottom of the rear seat, the lifting assembly includes a rotating arm and a connecting pin, the rotating arm is formed with an extension block on the side facing the seat, and the anti-slip portion is connected to the two side walls of the end of the extension block; a connecting portion is formed on the moving block, and the connecting pin passes through the rotating arm and the connecting portion, so that the rotating arm can be folded relative to the moving block and set at a right angle to it.

[0012] In the above-mentioned universal small table structure integrated at the bottom of the rear seat, the rotating assembly includes a rotating motor and a rotating plate, and 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, and the other end is movably hinged to the table assembly.

[0013] In the above-mentioned universal small table structure integrated at the bottom of the rear seat, a step groove is also formed on the rotating arm, and the step groove provides an escape space for the rotating plate and the table assembly when they are retracted to the side wall of the rotating arm.

[0014] In the above-mentioned universal small table structure integrated at the bottom of the rear seat, the table assembly includes: a support plate movably connected to an end of the rotating plate, wherein a limited surface is formed on the rotating plate, and when the support plate is folded relative to the rotating plate, it is movably pressed against the limited surface to place the small table body in the use state; The damper is provided with a mounting groove in the support plate, the damper is arranged in the mounting groove, and the small table body is connected to the rotating shaft of the damper.

[0015] In the above-mentioned universal small table structure integrated at the bottom of the rear seat, the small table body includes a first table and a second table hinged to each other, and the first table and the second table can be freely switched between an overlapping position and an unfolded use position.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The present invention provides a universal small table structure integrated at the bottom of the rear seat. By setting a guide structure with a specific track groove in the base and coordinating the linkage of the transmission component and the lifting component, the small table can realize the compound movement of "horizontally extending - folding the front end - vertically positioning - unfolding for use", ensuring that the small table can be smoothly unfolded from a hidden position at the bottom of the seat to a suitable height in front of the seat, with simple operation and smooth process. At the same time, the entire structure makes full use of the idle space under the seat to realize "hidden integration", expanding the functional configuration without affecting the riding comfort. It is particularly suitable for the rear seat layout of passenger cars with compact space, and significantly improves the user experience.

[0018] (2) The length of the second guide groove is greater than the length of the traction part. This offset length design ensures that the lifting component can obtain sufficient torque to complete the flipping action when it reaches the turning point of the trajectory, avoiding incomplete flipping due to premature separation; and the end of the second guide groove is on the same vertical line as the guide part, which is conducive to 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.

[0019] (3) A stepped groove is provided on the rotating arm to provide a clearance space for the rotating plate and table assembly when they are folded, allowing them to fit completely within the side wall of the rotating arm, greatly reducing the overall volume occupied by the structure. This design effectively achieves a compact layout of the multi-stage folding mechanism, allowing the entire small table system to be completely hidden under the seat when not in use, without affecting the interior aesthetics and passenger space. This is in line with the design trend of modern car interiors towards lightweight, miniaturization, and invisible integration. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0023] 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 position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0024] like Figures 1 to 6 As shown, the present invention provides a universal small table structure integrated at the bottom of the rear seat, including a base 1, a transmission assembly 2, a lifting assembly 3, a rotating assembly 4 and a table assembly 5.

[0025] Among them, the base 1 is installed at the bottom of the seat, and a track groove 10 is opened on the base 1; the transmission component 2 and the lifting component 3 are movably arranged in the base 1, and are used to drive the lifting component 3 to extend out of the base 1; the lifting component 3 is connected to the output end of the transmission component 2, and is movably engaged in the track groove 10, so that when the lifting component 3 moves to the end of the track groove 10, it is folded to a vertical posture relative to the output end; the rotating component 4 is connected to the lifting component 3, and is used to rotate the table component 5 to the top of the lifting component 3; the table component 5 is movably connected to the rotating component 4, and has a function of being able to be in a retracted state (reference Figure 1 and Figure 2 The structure shown, that is, placed in a vertical position) and in use (reference Figure 3 When the transmission assembly 2 drives the lifting assembly 3 to extend outside the seat along the length direction of the base 1, the lifting assembly can be folded to the front end of the seat relative to the transmission assembly 2 due to the track groove 10, so that the rotating assembly can cooperate with the table assembly 5 to switch the small table body 50 from the retracted state to the use state.

[0026] like Figure 1 As shown, the base 1 in this embodiment 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 set in the base 1 (this embodiment uses two sets to achieve Figure 3 The state shown meets the needs of users on the left and right seats). When the universal small table structure is fully retracted to Figure 1When the seat is in the seat 1, the small table body 50 is in a retracted state and is in close contact with the rotating assembly 4. At the same time, the rotating assembly 4 is also in close contact with the side wall of the lifting assembly 3, so that the entire structure is completely hidden under the seat bottom and does not protrude outside the seat contour. When the user triggers a control signal (such as a key or voice command), the transmission assembly 2 drives the lifting assembly 3 to extend horizontally outward along the length of the seat 1 (i.e., at Figure 1 During this process, the entire structure maintains a horizontal posture and gradually extends out of the space below the front end of the seat, such as Figures 1 to 3 As shown, as the lifting assembly 3 slides to the end of the track groove 10, the track groove 10 forces the lifting assembly 3 to rotate relative to the output end of the transmission assembly 2 (the rotation direction is toward one side of the seat), that is, the lifting assembly 3 is folded upward around the hinge point between it and the transmission assembly 2, and gradually rotates from a horizontal posture to a nearly vertical posture. This folding action lifts the table board assembly 5 from under the seat to the available height at the front end of the seat, completing the space conversion from "hidden to visible"; after the lifting assembly 3 is folded into place, the rotating assembly 4 is started to drive the table board assembly 5 to rotate 180 degrees, so that the table board assembly 5 can be above the lifting assembly 3 (at this time, the table board assembly 5 is still placed in a vertical posture and is in a retracted state, refer to Figure 2 ), so that the subsequent user can adjust the front or side position of the rear passenger when switching the table panel assembly 5 from the retracted state to the use state, realize the universal positioning function of the small table, and adapt to different sitting postures or usage needs. Therefore, the present invention realizes a fully automatic operation process of automatically extending, lifting, flipping and unfolding the small table from the bottom of the seat by integrating the collaborative structure of the base 1, transmission assembly 2, lifting assembly 3, rotation assembly 4 and table panel assembly 5 at the bottom of the seat. The structure cleverly uses the track groove 10 to guide the movement path of the lifting assembly 3, automatically triggering the folding action at the end of the extension stroke, and cooperating with the rotation assembly 4 and table panel assembly 5 to enable the small table panel body 50 to smoothly reach the front of the seat and adjust its posture. The overall structure is compact and the movement is coherent, which significantly improves the convenience and comfort of the rear passengers in using the small table. At the same time, the entire mechanism is hidden at the bottom of the seat, does not occupy the space in the car, and significantly improves the space utilization and aesthetics in the car, which is suitable for the intelligent configuration requirements of the rear row of high-end passenger cars.

[0027] The trajectory 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 close to the outside of the seat, and the lifting component 3 is connected to a first locking block 30, and the first locking block 30 can move back and forth in the guide portion 100a and the traction portion 100b; a second guide groove 101, which is arranged parallel to the first guide groove 100 and is not connected to each other, and the output end of the transmission component 2 is connected to the second locking block 20, and the second locking block 20 is movably connected in the second guide groove 101.

[0028] like Figures 1 to 3 As shown, by providing a first guide groove 100 consisting of a guide portion 100a and a traction portion 100b, and a second guide groove 101 parallel to but independently provided therewith, the sub-path motion control of the lifting component 3 and the output end of the transmission component 2 is realized; that is, in the process of the output end of the transmission component 2 driving the lifting component 3 to move, the first engaging block 30 slides in the guide portion 100a in advance, ensuring that the lifting component 3, the rotating component 4 and the table board component 5 can all be smoothly extended to the outside of the base 1. Preferably, the connecting portion of the guide portion 100a and the traction portion 100b in this embodiment adopts an arc transition. Therefore, as the output end of the transmission component 2 continues to apply driving force, the first engaging block 30 will slide from the end of the guide portion 100a into the traction portion 100b. Since the connecting line between the first engaging block 30 and the second engaging block 20 is inclined at this time (reference Figure 2 ), which also makes the lifting component 3 gradually fold from the horizontal position to the Figure 3 As shown in the vertical posture (the folding direction is toward the seat), during this process, the second engaging block 20 only makes linear motion in the second guide groove 101, which is used to transmit the driving force and prevent the lifting component 3 from being misplaced and causing jamming. This double-slot separation design avoids motion interference, improves transmission stability and structural reliability, effectively prevents jamming or misplacement, and enhances the smoothness and durability of the overall mechanism operation.

[0029] The length of the second guide groove 101 is greater than that of the guide portion 100 a , and the end portion of the second guide groove 101 close to the outer side of the seat is in the same vertical direction as the traction portion 100 b .

[0030] like Figure 2 and Figure 3 As shown, as the transmission assembly 2 is started, the first engaging block 30 and the second engaging block 20 are pushed to slide in the guide portion 100a and the second guide groove 101 respectively. Since the traction portion 100b is perpendicular to the guide portion 100a, the front end of the lifting assembly 3 ( Figure 1The leftmost end shown in the figure is pulled up, and since the second engaging 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 the end), the rear end of the lifting component 3 (the hinge with the transmission component 2) continues to move forward, and is then pulled upward by the front end to form a flipping movement around the hinge of the lifting component 3 and the transmission component 2, until the lifting component 3 gradually flips from a horizontal position to a nearly vertical position; therefore, the length of the second guide groove 101 in this embodiment 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 After completing the vertical folding, component 3 still maintains its supporting and guiding functions. In addition, due to the cooperation of the guiding 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, and the transmission connection is not locked, allowing the lifting component 3 to perform fine-tuning and posture transition during the folding process to avoid rigid jamming. This design extends the effective transmission range within a limited space, making the lifting process smoother and more controllable, especially at the folding turning point. It can still provide continuous power support to avoid action failure or vibration noise due to power interruption, thereby improving user experience and system response accuracy.

[0031] The first engaging block 30 and the second engaging block 20 both include an anti-slip portion 600 and a snap-fit ​​portion 601. The anti-slip portion 600 and the snap-fit ​​portion 601 are coaxially arranged. The anti-slip portion 600 can move against the inner wall of the base 1 when the snap-fit ​​portion 601 extends into the first guide groove 100 or the second guide groove 101.

[0032] like Figure 3 and Figure 4 As shown, the engaging portion 601 in this embodiment is used to slide within the first guide groove 100 and the second guide groove 101. At the same time, the anti-slip portion 600 always adheres to the inner wall of the base 1 to form a stable support, effectively preventing the engaging block from axially falling off due to vibration or lateral force, thereby ensuring the smoothness and stability of the sliding process of the engaging portion 601. This structure effectively prevents the engaging block from detaching from the guide groove under a vibrating environment, greatly enhances the connection strength and safety of the kinematic pair, improves the impact resistance and long-term stability of the overall structure, and meets the standard requirements for high reliability of automotive parts. Preferably, in this embodiment, a low-friction material (such as a PTFE coating or a nylon gasket) can be provided between the anti-slip portion 600 and the inner wall of the base 1 to ensure smooth sliding.

[0033] The transmission assembly 2 includes: a mounting seat 21, a base 1 is provided with a storage cavity 11 along its length direction, and the mounting seat 21 is arranged in the storage cavity 11; a screw rod 22 and a driving member 23, one end of the screw rod 22 is arranged on the mounting seat 21, and the other end is connected to the driving end of the driving member 23 to drive the screw rod 22 to rotate in the storage cavity 11; a moving block 24, which is movably connected to the screw rod 22, and the lifting assembly 3 is movably hinged to the moving block 24, and the second locking block 20 is connected to the two side walls of the moving block 24.

[0034] like Figures 3 to 5 As shown, this embodiment adopts a transmission assembly 2 composed of a screw rod 22, a driving member 23 (such as a stepping motor or a servo motor) and a moving block 24. The screw rod 22 transmission itself has the advantages of high transmission accuracy, good self-locking performance and low noise. By installing the screw rod 22 on the mounting seat 21 in the storage cavity 11, and utilizing the moving block 24 to cooperate with the screw rod 22 thread, the hinge-connected lifting assembly 3 is driven to achieve linear reciprocating motion. The structure is compact and easy to integrate. At the same time, this transmission method has rapid response and precise control, and is suitable for automated control. It can realize one-button expansion / retraction function in conjunction with the vehicle power system, thereby enhancing the intelligent experience.

[0035] 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, and the anti-slip portion 600 is connected to the two side walls of the end of the extension block 310; a connecting portion 240 is formed on the moving block 24, and the connecting pin 32 passes through the rotating arm 31 and the connecting portion 240, so that the rotating arm 31 can be folded relative to the moving block 24 and set at a right angle to it.

[0036] like Figures 3 to 5As shown, in the stowed state, the rotating arm 31 of this embodiment is generally horizontal, with its front end connected to the rotating assembly 4 and its rear end connecting pin 32 hingedly connected to the connecting portion 240 on the moving block 24, thereby forming a foldable, movable connection structure. Specifically, due to the certain distance between the extension block 310 and the moving block 24 and the fact that the extension block 310 is connected to the first engaging block 30, as the second engaging block 20 moves within the second guide groove 101, the first engaging block 30 rises along the traction portion 100b, and the rotating arm 31 is constrained by its trajectory and forced to rotate about the connecting pin 32, ultimately forming a right angle with the moving block 24, achieving automatic erection. It is worth noting that since the position between the extension block 310 and the movable block 24 remains unchanged, when the rotating arm 31 gradually approaches the vertical posture, the first locking block 30 will gradually descend from the top of the traction part 100b to a certain height (but will not separate from the traction part 100b) to adapt to the height difference between the extension block 310 and the movable block 24. At the same time, the first locking block 30 and the second locking block 20 are respectively connected to 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 shake or even mislock when using the small table board body 50.

[0037] 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, and the other end is movably hinged to the table top assembly 5.

[0038] like Figures 3 to 6 As shown, as the first engaging block 30 slides from the guide portion 100a into the traction portion 100b, the rotating arm 31 gradually tilts and adjusts toward the upright position, as shown in FIG. Figure 2 The structure shown is that the rotating arm 31 is at a 45-degree angle. Under the condition that the table top assembly 5 does not interfere with any part (base 1), the rotating motor 40 in this embodiment can control the rotating plate 41 to rotate from a position close to the side wall of the rotating arm 31 to the upper part of the rotating arm 31 (i.e. Figure 3 The rotating plate 41 shown is in the same vertical direction as the rotating arm 31, so that the table assembly 5 can be flexibly rotated to the optimal position in front of the passenger to adapt to different body shapes or usage scenarios (such as left / right seat use). This electric rotation method is easy to operate and has accurate positioning, significantly improving 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 in the positions shown are performed synchronously, which effectively shortens the time required for the universal small table structure to be unfolded and used as a whole, and avoids the user's overall user experience being affected by long waiting.

[0039] A stepped groove 311 is also formed on the rotating arm 31 , which provides an escape space for the rotating plate 41 and the table top assembly 5 when they are retracted to the side wall of the rotating arm 31 .

[0040] like Figure 5 As shown, this embodiment also provides a stepped groove 311 on the rotating arm 31 to provide an avoidance space for the rotating plate 41 and the table board assembly 5 in the retracted state, that is, when the table board assembly 5 is folded and fits against 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 board is completely hidden under the seat, does not affect the neatness of the seat appearance and riding safety, and also avoids the risk of scratches by foreign objects.

[0041] The table top assembly 5 includes: a support plate 51, which is movably connected to the end of the rotating plate 41. A limited surface 410 is formed on the rotating plate 41. When the support plate 51 is folded relative to the rotating plate 41, it is movably pressed against the limited surface 410 to place the small table top body 50 in use state; a damper 52, an installation groove 510 is opened in the support plate 51, the damper 52 is arranged in the installation groove 510, and the small table top body 50 is connected to the rotating shaft of the damper 52.

[0042] like Figures 3 to 5 As shown, as the rotating motor 40 rotates the rotating plate 41 to the top of the rotating arm 31 (as shown in FIG. Figure 3 As shown), at this time, the support plate 51 can be pre-folded relative to the rotating plate 41 (the folding direction is along the width direction of the rotating plate 41, that is, Figure 3 In the horizontal direction shown in the figure), during this process, the support plate 51 is tightly matched with the rotating plate 41 through the limiting surface 410 to form a stable supporting structure to prevent the table top from shaking or sinking, thereby ensuring sufficient bearing capacity; at the same time, this embodiment also provides a damper 52 in the support plate 51, and by connecting the small table plate body 50 to the rotating shaft, the small table plate body 50 can be relatively moved along the support plate 51. Figure 3 The (horizontal) position is adjusted in the horizontal direction to ensure that it can be accurately located at the position 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 be impact-free and silent, thereby improving the opening and closing feel, enhancing the product's sense of luxury and safety, and is particularly suitable for children's riding environments.

[0043] The small table board body 50 includes a first table board 500 and a second table board 501 that are hinged to each other. The first table board 500 and the second table board 501 can be freely switched between an overlapping position and an unfolded use position.

[0044] like Figure 5 As shown, the small table body 50 in this embodiment is composed of a first table board 500 and a second table board 501 that are hinged to each other and can be in an overlapping position (refer to Figure 2 Structure shown) and expanded use state (reference Figure 5 This folding design significantly increases the usable desktop area, meeting the needs of multiple people sharing or multitasking (such as storing a laptop and a water cup). It also folds down to a smaller size when not in use for easy storage. The overall flexible and practical structure expands the functional boundaries of the small table, improving space utilization and user experience.

[0045] like Figures 1 to 6 As shown, this embodiment integrates the universal small table structure into the base 1 and places it at the bottom of the middle seat in the rear row. This can not only save space in the entire vehicle and effectively utilize the idle space under the seat for hidden arrangement, but also solve the problem that the cup holder structure is set in the traditional armrest and cannot meet the space design requirements of the small table structure. At the same time, the track groove 10, the linkage folding structure of the lifting component 3 and the transmission component 2 are integrated, combined with the rotating component 4 and the switchable small table body 50, to realize a multi-degree-of-freedom integrated motion control structure in which the small table automatically extends from the bottom of the seat, folds and positions, and is unfolded for use. Preferably, this embodiment can also be connected to an anti-slip plate 12 at the top position of the base 1, as shown in FIG. Figure 1 As shown, the anti-slip plate 12 can confine the overall structure of the universal small table within the base 1, preventing the various components from being misaligned or even slipping out of the base 1 due to vibration during vehicle driving, thereby improving the overall stability of the structure.
