Description

Technical Field

[0001] This disclosure relates to an in-vehicle table assembly and a vehicle, belonging to the field of vehicle-related technical technology. Background Technology

[0002] Most existing rear-seat tables in vehicles are integrated with the rear armrest, with the table hinged to the top of the armrest or fixed to the front. In this structure, the table and its supporting mechanism are concentrated in the armrest area, resulting in a high and forward center of gravity (for example, the table and its supporting mechanism typically weigh around 3 kg, while the armrest itself often weighs less than 7 kg, making the overall structure top-heavy). In the event of a collision, the table may separate from the armrest and fly towards the rear passenger area due to inertia, causing secondary injuries to the occupants.

[0003] Existing integrated structures typically employ sliding rails located on the bottom of the tabletop or retractable tabletops composed of two or more panels to extend and retract the tabletop, and a rotating disc to allow the tabletop to rotate horizontally. However, the sliding rails are exposed beneath the tabletop, the seams between the retractable tabletop panels affect aesthetics and flatness, and the rotating disc being located on the bottom of the tabletop results in a complex overall structure and a cumbersome assembly process.

[0004] Therefore, there is room for improvement in existing vehicle-mounted table assemblies in fundamentally eliminating the collision safety hazards caused by the aforementioned center of gravity shift and in simplifying the connection structure between the table and its support mechanism. Summary of the Invention

[0005] To address the aforementioned problems in the prior art, this disclosure proposes a vehicle-mounted table assembly and a vehicle. This assembly improves occupant safety and simplifies the connection structure between the table and its support mechanism by separating the table from the armrest and embedding its support mechanism (e.g., a table arm) within the table. In its stowed state, the vehicle-mounted table assembly is integrally arranged in the area between the seat armrest and the seat back, with the table resting against the area between the seat back and the seat. The vehicle-mounted table assembly can be pulled upwards and flipped forward to a horizontal position for occupant use.

[0006] Specifically, the first aspect of this disclosure provides a vehicle-mounted table assembly, comprising: a table, wherein a guide channel is provided inside the table along a preset direction; and a table arm, wherein the table arm passes through the guide channel and slidably engages with the guide channel, such that the table can slide along the table arm between a retracted position and an extended position; the table arm includes a first arm segment and a second arm segment hinged to each other by a hinge member, the second arm segment being used to directly or indirectly connect to a vehicle body or a seat; in the retracted position, the first arm segment is entirely housed within the guide channel, and the second arm segment is at least partially housed within the guide channel; in the extended position, the second arm segment is entirely located outside the guide channel, the first arm segment is partially housed within the guide channel, and the table panel rotates relative to the second arm segment about the hinge member along with the first arm segment.

[0007] The vehicle-mounted table assembly with the above configuration avoids the problems of existing external sliding rails or bracket-type tables occupying space and affecting aesthetics. At the same time, the connection structure between the table and the table arm is simple, and there is no need to set up a complicated rotation mechanism. The usage position can be adjusted by rotating the table along with the first arm segment around the hinge.

[0008] Preferably, in the vehicle-mounted table assembly of the first aspect, the guide channel is provided with a protruding rib extending along the preset direction.

[0009] According to the vehicle-mounted table assembly with the above configuration, by setting ribs in the guide channel, guide and limit can be achieved, so that the table slides smoothly along the table arm and remains horizontal, preventing the table from deflecting during the sliding process.

[0010] Preferably, in the vehicle-mounted table assembly of the first aspect, the outer surface of the table arm is provided with a groove extending along the preset direction, and the groove and the convex rib complement each other.

[0011] According to the vehicle-mounted table assembly with the above configuration, by providing a groove on the table arm that is complementary to the convex rib, the convex rib can be embedded in the groove to form a slide rail pair, so that the table can slide smoothly.

[0012] Preferably, in the vehicle-mounted table assembly of the first aspect, the first arm segment includes a sliding segment adjacent to the second arm segment and a stop segment away from the second arm segment, the sliding segment having the groove, the stop segment not having the groove, and the rib being able to abut against the stop segment to prevent the first arm segment from dislodging from the guide channel.

[0013] According to the vehicle-mounted table assembly with the above configuration, by dividing the first arm segment into a sliding segment with the groove and a stop segment without the groove, the first arm segment can be prevented from completely disengaging from the guide channel by axial limiting between the rib and the stop segment when the table slides to the end.

[0014] Preferably, in the vehicle-mounted table assembly of the first aspect, the first arm segment and the second arm segment are hinged by a vertical pin, such that the first arm segment can rotate 90° to the left or right relative to the second arm segment in the horizontal plane.

[0015] According to the vehicle table assembly with the above configuration, the hinge between the first arm segment and the second arm segment is achieved by using a vertical pin, so that the table can be rotated 90° to the left or right for use by the occupant on the left or right side seat.

[0016] Preferably, in the vehicle-mounted table assembly of the first aspect, the cross-section of the guide channel is circular or rectangular, and / or the cross-sections of the ribs and the grooves are rectangular, trapezoidal, or dovetail-shaped.

[0017] According to the vehicle-mounted table assembly with the above configuration, the cross-sectional shape makes the guide channel and table arm, convex rib and groove complement each other, and the table slides smoothly and does not wobble.

[0018] Preferably, in the vehicle table assembly of the first aspect, the vehicle table assembly has a folded state, in which the vehicle table assembly is arranged as a whole between the backrests of the rear seats and in the area behind the rear armrest, and is separated from the rear armrest.

[0019] According to the vehicle-mounted table assembly with the above configuration, the entire assembly is placed between the backrests and behind the armrests in the folded state, separate from the armrests. Compared with the integrated layout of the table on the armrest in the prior art, this achieves weight distribution and eliminates the collision safety hazards caused by the shift in the center of gravity.

[0020] Preferably, in the vehicle table assembly of the first aspect, the second arm segment has a transverse arm at the end opposite to the end where the hinge is located, and the transverse arm is rotatably connected to the back of the rear seat, so that the second arm segment can be flipped from a state parallel to the back of the rear seat to a horizontal state in a vertical plane.

[0021] According to the vehicle table assembly with the above configuration, the table assembly can be directly installed between the backrests of the rear seats and flipped forward via the lateral arm.

[0022] Preferably, in the vehicle table assembly of the first aspect, the table arm further includes a third arm segment, which is connected to the opposite end of the second arm segment to the end where the hinge is located. The third arm segment is located behind the rear armrest and fixed to the back of the rear seat. The second arm segment is hinged to the third arm segment by a horizontal hinge, so that the second arm segment can be flipped from a state parallel to the back of the rear seat to a horizontal state in the vertical plane around the horizontal hinge.

[0023] With the vehicle table assembly having the above configuration, by adding a third arm section, a portion of the table assembly can be placed at a lower position behind the armrest, thus providing better concealment and making fuller use of the limited space.

[0024] A second aspect of this disclosure provides a vehicle that includes the vehicle-mounted table assembly according to the first aspect, which also achieves the various technical effects described above in the vehicle-mounted table assembly of the first aspect. Attached Figure Description

[0048] First Embodiment

[0049] Figure 1 This is a schematic diagram showing the tabletop and table arm of the vehicle-mounted table assembly according to the first embodiment, wherein, Figure 1 (a) shows an exemplary retracted position of the tabletop. Figure 1 (b) shows an exemplary extended position of the tabletop.

[0050] like Figure 1 As shown, the vehicle-mounted table assembly of this disclosure includes: a table 1, the table 1 having a guide channel 11 extending in a preset direction inside; and a table arm 2, the table arm 2 passing through the guide channel 11 and slidingly engaging with the guide channel 11, so that the table 1 can move along the table arm 2. Figure 1 The retraction position shown in (a) is the same as Figure 1 The table 1 slides between the extended positions shown in (b). In this embodiment, the direction in which the table 1 slides from the retracted position to the extended position is defined as the extension direction, and the front side of the extension direction is defined as the "tipping side" and the opposite side is defined as the "end side".

[0051] In this embodiment, the tabletop 1 is, for example, a rectangular tabletop, and the preset direction is its own length direction, that is, the guide channel 11 extends along the length direction of the tabletop 1. The table arm 2 is a rod, including a first arm segment 21 and a second arm segment 22 hinged to each other by the hinges described below. The second arm segment 22 is disposed at the end of the first arm segment 21 and is used to directly or indirectly connect to the vehicle body or seat. Figure 1As shown in (a), in the retracted position of the tabletop 1, the first arm segment 21 of the table arm 2 is entirely accommodated within the guide channel 11, while the second arm segment 22 is at least partially accommodated within the guide channel 11; as Figure 1 As shown in (b), in the extended position of the tabletop 1, the second arm segment 22 is entirely outside the guide channel 11, while the first arm segment 21 is partially accommodated within the guide channel 11, and the tabletop 1 can rotate relative to the second arm segment 22 around the hinge along with the first arm segment 21.

[0052] It should be noted that the recovery location described in this disclosure is not limited to... Figure 1 The position shown in (a) is not limited to the extended position described in this disclosure. Figure 1 The position shown in (b). Specifically, the retracted position described in this disclosure may include any position of the tabletop 1 from the second arm segment 22 being entirely housed within the guide channel 11 to the point where the hinge of the first arm segment 21 and the second arm segment 22 is about to be exposed outside the guide channel 11, in which the tabletop 1 cannot rotate about the hinge because the hinge is located within the guide channel 11.

[0053] The “extended position” described in this disclosure can include any position where the hinge is just exposed outside the guide channel 11 to the end of the sliding range of the table 1. In the extended position, the second arm segment 22 is completely outside the guide channel 11, and the first arm segment 21 is partially outside the guide channel 11 (the hinge is exposed). The table 1 can rotate around the hinge relative to the second arm segment 22 along with the first arm segment 21. Thus, passengers can freely choose the timing of rotation of the table 1 within the sliding range according to their own needs (e.g., body shape or sitting posture).

[0054] like Figure 1 As shown in (a), the guide channel 11 of the tabletop 1 is configured as a cylindrical hole in this embodiment. In this case, both the first arm segment 21 and the second arm segment 22 of the table arm 2 are cylindrical, with their outer diameter configured to be slightly smaller than the inner diameter of the guide channel 11 of the tabletop 1 to facilitate sliding. They can be made of aluminum alloy or steel. The second arm segment 22 is the main long segment of the table arm 2, longer than the first arm segment 21, and is the main mating and guiding segment during the sliding process of the tabletop 1.

[0055] like Figure 1As shown in (a) and (b), the table arm 2 may further include a third arm segment 23, which is connected to the end portion of the second arm segment 22 at the end side of the second arm segment 22. In this case, the second arm segment 22 is indirectly connected to the vehicle body or seat via the third arm segment 23. As an example, when the vehicle table assembly is installed between the rear seat backs behind the rear armrest, the third arm segment 23 is located behind the rear armrest and fixed to the rear seat back. More specifically, in the area behind the rear armrest, the third arm segment 23 may be close to the rear end of the armrest and fixed to the frame of the rear seat back or the vehicle floor by bolts or welding. The third arm segment 23 extends diagonally upward and rearward towards the vehicle, and the height of its top end may be slightly higher than or flush with the top surface of the rear armrest. At the top end of the third arm segment 23 and at the end of the second arm segment 22, a horizontal hinge 231 is provided to hinge the second arm segment 22 and the third arm segment 23, with its hinge axis arranged in the horizontal direction (the lateral direction of the vehicle). Therefore, partial planes can be provided at the end of the second arm segment 22 and the top of the third arm segment 23, and the two hinge plates of the horizontal hinge 231 are respectively embedded in these two planes. In this way, the second arm segment 22 can rotate forward about 110-125° (i.e., 90° + the rearward tilt angle of the rear seat back relative to the vertical direction) about the horizontal hinge 231 from a retracted state that is roughly parallel to the rear seat back to a horizontal state. When the vehicle table assembly A is in the retracted state, a part of the third arm segment 23 and the horizontal hinge 231 can also be accommodated in the guide channel 11 of the table 1.

[0056] Figure 2 This is a perspective view of the tabletop according to the first embodiment, showing the guide channel of the tabletop and the protruding ribs therein; Figure 3 This is a perspective view of the tabletop according to the first embodiment, viewed from the other end, showing the guide channel of the tabletop. Figure 4 This is a cross-sectional schematic diagram of the tabletop according to the first embodiment, showing the guide channel of the tabletop and the protruding ribs therein, wherein, Figure 4 (a) shows a longitudinal section of the tabletop. Figure 4 (b) shows the cross-section of the tabletop along GG. Figure 4 (c) shows the cross-section of the tabletop along HH.

[0057] like Figures 2 to 3As shown, the tabletop 1 in this embodiment is a rectangular plate, but it is not limited to this. The tabletop 1 can be any other suitable shape, such as a circular plate, a semi-circular plate, a trapezoidal plate, a rounded rectangular plate, a fan-shaped plate, an oblong plate, etc. Furthermore, as the main component supporting items, the material selection for the tabletop 1 needs to consider structural strength, lightweighting, and the aesthetics of the vehicle interior. For example, the tabletop 1 can be made of thermoplastic engineering plastics (such as ABS, PP, or PC) or lightweight metals (such as aluminum alloy or magnesium alloy). The tabletop 1 can be a single-layer integral structure or a composite laminate structure, such as a composite board with plastic or metal as the internal skeleton and a surface covered with leather, fabric, or wood grain veneer, thereby improving visual and tactile quality while fulfilling structural functions. The tabletop 1 can be manufactured using injection molding or extrusion molding, depending on the materials used. In this respect, the shape, material, and processing method of the tabletop 1 are not particularly limited.

[0058] like Figures 2 to 3 As shown, the guide channel 11 of the tabletop 1 may include, for example, a cylindrical hole. A certain sliding gap can be left between the guide channel 11 and the table arm 2 to ensure that the tabletop 1 can slide smoothly along the table arm 2 without significant wobbling. The guide channel 11 may be provided with a rib 12 extending along its length to guide the table arm 2 and prevent it from dislodging from the guide channel 11. For example, in the end region of the guide channel 11 at its end, the inner wall (e.g., top wall, side wall, or bottom wall) of the guide channel 11 may protrude inward to form a rib 12 extending along its length. Preferably, with... Figure 2 For example, the top wall of the guide channel 11 can protrude downward to form a rectangular rib extending along its length. The axial extension length of this rectangular rib can be approximately 20-50 mm, accounting for only a small portion of the total length of the guide channel 11. The rib 12 can be integrally formed with the inner wall of the guide channel 11, for example, by die casting, or it can be formed by removing material from the inner wall of the guide channel 11 (e.g., by milling). In this respect, the machining method of the rib 12 is not particularly limited.

[0059] Preferably, a threaded hole (not shown) may be provided on one side of the tabletop 1 in the width direction. The threaded hole extends in a direction perpendicular to the guide channel 11 and communicates with the guide channel 11. The threaded hole is equipped with a locking knob (not shown). When the user slides the tabletop 1 to the desired position, the locking knob can be tightened inward so that its end abuts against the outer surface of the first arm segment 21, thereby using friction to fix the tabletop 1 and prevent the tabletop 1 from continuing to slide or retract.

[0060] Figure 5 This is a schematic diagram of the first arm segment of the table arm according to the first embodiment, showing the sliding segment and the stop segment of the first arm segment, wherein, Figure 5 (a) shows a three-dimensional view of the first arm segment. Figure 5(b) shows the cross-section of the stop section. Figure 5 (c) shows the cross-section of the sliding section. Figure 6 It is a longitudinal cross-sectional view showing the contact between the protruding rib of the tabletop and the stop section of the first arm segment.

[0061] The outer surfaces of the first arm segment 21 and the second arm segment 22 of the table arm 2 are provided with grooves 24 extending along the length direction, which complement the ribs 12. The ribs 12 are embedded in the grooves 24 and slide within them, providing guidance for the sliding of the tabletop 1 and preventing the tabletop 1 from rotating around the central axis of the table arm 2, thus ensuring that the tabletop 1 maintains a stable horizontal posture during sliding. Preferably, when the ribs 12 of the guide channel 11 are rectangular ribs, the grooves 24 provided on the corresponding outer surfaces (e.g., top surface, side surface, or bottom surface) of the first arm segment 21 and the second arm segment 22 of the table arm 2 are correspondingly configured as rectangular grooves extending along the length direction to cooperate with the rectangular ribs. The rectangular grooves 24 can have a shape and size corresponding to the rectangular ribs.

[0062] like Figure 5 As shown in (a), the first arm segment 21 includes a sliding segment 211 adjacent to the second arm segment 22 and a stop segment 212 away from the second arm segment 22. The sliding segment 211 is provided with a groove 24, while the stop segment 212 is not provided with a groove 24. Therefore, the groove 24 forms a blind groove in the first arm segment 21, open at one end and closed at the other end by the stop segment 212. More specifically, as... Figure 5 As shown in (a), since the stop section 212 is not provided with the groove 24, it is a complete cylinder (i.e., a solid cylinder) and its length can be approximately 10-30 mm. When the table 1 slides to the end, the rib 12 abuts against the stop section 212 to prevent the first arm section 21 from dislodging from the guide channel 11.

[0063] like Figure 6 As shown, the protruding rib 12 of the tabletop 1 can slide forward along the groove 24 of the sliding section 211 of the first arm section 21. When the protruding rib 12 of the tabletop 1 slides to the stop section 212 of the first arm section 21, the protruding rib 12 abuts against the end face of the stop section 212, thereby preventing the tip of the first arm section 21 from coming out of the end of the guide channel 11 and restricting the tabletop 1 from continuing to slide forward.

[0064] Figure 7 This is a schematic diagram of the second arm segment of the table arm according to the first embodiment, showing the groove of the second arm segment, wherein, Figure 7 (a) shows a three-dimensional view of the second arm segment. Figure 7 (b) shows the cross-section of the second arm segment.

[0065] like Figure 7As shown in (a), the second arm segment 22 of the table arm 2 can be cylindrical in shape. Along the entire length of the second arm segment 22, its top surface can be provided with a groove 24. The groove 24 of the second arm segment 22 has the same shape and size as the groove 24 of the first arm segment 21. For example, it is also a rectangular groove that is recessed downward from the top surface and extends through the axial direction.

[0066] Figure 8 This is a partially enlarged schematic diagram showing the vertical pin used to hinge the first and second arm segments and its connecting structure.

[0067] like Figure 8 As shown, the first arm segment 21 and the second arm segment 22 are hinged together by a hinge joint, allowing the first arm segment 21 to rotate relative to the second arm segment 22 in the horizontal plane around a vertical pin 213. In this embodiment, the hinge joint is a vertical pin 213, but this disclosure is not limited to this. For example, it can also be a spherical joint, a spherical bearing structure, etc., as long as it can achieve 90-degree rotation to the left and right.

[0068] Specifically, such as Figure 8 As shown, the end portion of the first arm segment 21 is provided with a pin receiving cavity 214 for mounting a vertical pin 213. For example, the pin receiving cavity 214 can be located in the length direction of the first arm segment 21. Figure 1 One end of the vertical pin 213 is open in the x-direction and can be formed into a pocket-shaped structure or a semi-circular structure. The upper and lower ends of the vertical pin 213 are fixed to the top and bottom walls of the pin receiving cavity 214, respectively. That is, the vertical pin 213 is vertically installed in the pin receiving cavity 214 and does not protrude from the bottom surface of the groove 24 so as to avoid hindering the sliding of the rib 12 in the groove 24.

[0069] Correspondingly, the front end of the second arm segment 22 is provided with a connecting tab 221 extending toward the first arm segment 21 for connection with the vertical pin 213. For example, the connecting tab 221 can be a rectangular or semi-circular plate-shaped member. The front end of the connecting tab 221 is provided with a central hole 222, the diameter of which is slightly larger than the diameter of the vertical pin 213.

[0070] The vertical pin 213 passes through the center hole 222 of the connecting tab 221 to connect the first arm segment 21 and the second arm segment 22 together, so that the first arm segment 21 can rotate to the left or right relative to the second arm segment 22 in the horizontal plane about the vertical pin 213.

[0071] Optionally, the two transverse sidewalls of the pin receiving cavity 214 may each be provided with horizontal positioning grooves (not shown) extending outward from the pin receiving cavity 214 to the outer surface of the first arm segment 21. These horizontal positioning grooves open at the end face of the first arm segment 21 and extend along the axial direction (x-direction) of the first arm segment 21 to a position corresponding to the axis of the vertical pin 213. They are used to receive the connecting tab 221 when the first arm segment 21 rotates approximately 90° to the left or right relative to the second arm segment 22 about the vertical pin 213. That is, when the first arm segment 21 rotates approximately 90° to the left or right relative to the second arm segment 22 about the vertical pin 213, the connecting tab 221 is blocked by the wall of the horizontal positioning groove, thus limiting its further rotation. The upper and lower surfaces of the connecting tab 221, corresponding to the horizontal positioning groove, may be provided with elastic friction material so that after the connecting tab 221 enters the horizontal positioning groove, it rubs against the top and bottom walls of the horizontal positioning groove, thereby providing appropriate holding force to prevent the connecting tab 221 from accidentally sliding out of the open end of the horizontal positioning groove under normal use. When the table 1 needs to be retracted, the user is allowed to apply greater force to make the connecting tab 221 slide out of the horizontal positioning groove.

[0072] Figure 9 This is a front view of a vehicle rear seat using the in-vehicle table assembly A according to the first embodiment, wherein the in-vehicle table assembly A is in a stowed state. Figure 10 This is a perspective view of the rear seat of a vehicle using the in-vehicle table assembly A according to the first embodiment, showing the unfolded state of the in-vehicle table assembly A; Figure 11 This is a perspective view of the rear seat of a vehicle using the in-vehicle table assembly A according to the first embodiment, showing the table in a rotated state.

[0073] The following will combine Figures 9 to 11 Briefly describe the usage process of the vehicle-mounted table assembly A according to this embodiment.

[0074] First of all, Figure 9 In the folded state shown, the vehicle table assembly A can be arranged as a whole between the rear seat backs C and in the area behind the rear armrest B, separated from the rear armrest B. The vehicle table assembly A is positioned roughly parallel to the rear seat backs C, with a portion of the first arm segment 21, the second arm segment 22, and the third arm segment 23 retracted within the guide channel 11 of the table 1.

[0075] When needed, the user can pull the tabletop 1 upwards a short distance, exposing the horizontal hinge 231 from the guide channel 11. Then, the tabletop 1, along with the first arm segment 21 and the second arm segment 22, flips forward around the horizontal hinge 231 between the second arm segment 22 and the third arm segment 23, changing from a retracted state to a horizontal state. At this time, the rear armrest B provides support for the second arm segment 22 and the tabletop 1. When the user pulls the tabletop forward, the tabletop 1 slides forward into the vehicle via the guiding action of the rib 12 within the groove 24 of the table arm 2. Figure 10 As shown.

[0076] Then, the tabletop 1 continues to slide forward until the second arm segment 22 is fully exposed from the guide channel 11 of the tabletop 1 and the first arm segment 21 is partially exposed, as shown. Figure 11 As shown, the hinge between the first arm segment 21 and the second arm segment 22 is located outside the guide channel 11. The user can rotate the table 1 approximately 90° to the left or right in the horizontal plane along with the first arm segment 21. At this time, as described above, the connecting tab 221 of the second arm segment 22 is held in the horizontal positioning groove (not shown) of the first arm segment 21, and the user can tighten the locking knob on the side of the table 1 to abut against the outer surface of the first arm segment 21, thereby fixing the table 1 and preventing the table 1 from continuing to slide or retract. Therefore, the table 1 can be stably positioned in front of the left or right seat for the user to place items or to work, entertain, or rest. In this embodiment, the vehicle table assembly A with the aforementioned structure can improve the support stability of the table when carrying items or under pressure, which is sufficient to support the user lying down, elbow pressure, or placing heavy luggage or items.

[0077] Second Embodiment

[0078] Figure 12 This is a schematic diagram of the vehicle-mounted table assembly according to the second embodiment. Figure 12 As shown, the difference between the vehicle table assembly of this embodiment and the first embodiment is that the table arm 2 does not have a third arm segment 23, and the rear end of the second arm segment 22 is provided with a transverse arm 223. When the vehicle table assembly is installed behind the rear armrest between the rear seat backs, the two ends of the transverse arm 223 are rotatably connected to the rear seat back C. More specifically, the rear end of the second arm segment 22 can be integrally formed or welded with the transverse arm 223, and the two ends of the transverse arm 223 are rotatably inserted into the corresponding holes or supports of the rear seat back C on both sides. Here, in order to enable the entire vehicle table assembly to smoothly flip forward from the folded state to the horizontal state without interference from the rear armrest B, the transverse arm 223 can be fixed to the rear seat back C on both sides at a position slightly higher than the rear armrest B. The remaining structures of this embodiment are the same as those of the first embodiment, and will not be described again here.

[0079] The second embodiment omits the third arm segment 23 and the horizontal hinge 231, resulting in a simpler structure, lower cost, and one less hinge wear point, thus improving reliability. This arrangement is more suitable for situations where there is insufficient or no space behind the rear armrest.

[0080] Variations

[0081] The above embodiments are merely preferred embodiments of this disclosure and are not intended to limit this disclosure. Those skilled in the art can make various variations and modifications to the above embodiments without departing from the core principles of this disclosure.

[0082] For example, in the above embodiment, the tabletop 1 is shown as a rectangular plate. However, the tabletop 1 can also adopt other shapes, such as an L-shaped plate or a T-shaped plate. When such a shape is adopted, the tabletop 1 can directly cover the usage area of ​​one side or the left and right sides of the occupants by sliding out along the table arm 2, without relying on the rotation of the first arm segment 21 around the vertical pin 213. Accordingly, the rotational hinge structure such as the vertical pin 213, the pin receiving cavity 214, the connecting protrusion 221, and the center hole 222 can be simplified or omitted, and the first arm segment 21 and the second arm segment 22 can be fixedly connected or integrally formed. However, it should be noted that the storage volume of the L-shaped plate or the T-shaped plate is larger than that of the rectangular plate. In application scenarios where the arrangement space is limited or the arrangement space is rectangular, the rectangular plate solution is still suitable.

[0083] For example, in the above embodiment, the guide channel 11 of the tabletop 1 is provided with a rib 12 only at the end and the first arm segment 21 is provided with a stop segment 212 to prevent the first arm segment 21 from detaching. However, this disclosure is not limited to this. For example, the rib 12 can be provided along the entire length of the guide channel 11 of the tabletop 1, and the groove 24 can be provided along the entire range of the table arm 2 (i.e., the first arm segment 21 does not form the stop segment 212). In this case, an elastic buckle structure can be used to achieve anti-detachment limiting. For example, an elastic button can be provided at the end of the inner wall (e.g., top wall or side wall) of the guide channel 11. The elastic button is supported by a spring or elastic sheet and protrudes slightly from the inner wall surface of the guide channel under normal conditions. Correspondingly, a spherical recess is provided at the corresponding position on the outer surface of the first arm segment 21. When the tabletop 1 slides along the table arm 2 until the elastic button is aligned with the spherical recess, the elastic button is engaged in the spherical recess under the action of elastic force, generating a positioning feel and preventing the tabletop 1 from continuing to slide forward. When it is necessary to retract the tabletop 1, a backward pushing force can be applied to the tabletop 1. The elastic button retracts under the pressure of the guide slope of the spherical recess and is unlocked, allowing the tabletop 1 to slide backward. This structure can achieve different positioning feel and anti-dislodgement strength by adjusting the elastic force of the elastic button and the depth of the spherical recess.

[0084] In addition, in the above embodiment, the cross-sections of the guide channel 11 and the table arm 2 (first arm segment 21 and second arm segment 22) are shown as circular; however, their cross-sections may also be rectangular.

[0085] Furthermore, in the above embodiment, the table arm 2 is shown as a single arm; however, the table arm 2 can also be configured as two or more arms arranged side by side, each passing through one or more parallel guide channels 11 within the tabletop 1. This can also achieve the effect described above.

[0086] In addition, in the above embodiment, the cross-section of the rib 12 and the groove 24 that mates with it is shown as rectangular. However, their cross-sections can also be trapezoidal or dovetail-shaped to provide a certain degree of vertical self-locking while achieving sliding guidance.

[0087] In addition, in the above embodiment, the rib 12 is provided in the guide channel 11 of the tabletop 1 and the groove 24 is provided on the table arm 2. However, this disclosure is not limited to this. For example, the groove can be provided in the guide channel 11 and the rib that cooperates with the groove can be provided on the table arm 2.

[0088] In addition, although the vehicle table assembly of this disclosure is shown as being located behind the rear armrest and arranged between the rear seats in the above embodiments, it is obvious that the installation position of the vehicle table assembly is not limited to this, but can also be installed on the vehicle body, the side of the front or rear seats, or between the front seats.

[0089] The specific embodiments described above do not constitute a limitation on the scope of protection of this disclosure. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions are possible depending on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this disclosure are included within the scope of protection of this disclosure.
