Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, specifically to rear seat tables for automobiles and automobiles. Background Technology

[0002] Due to the changing work and lifestyles of people, passengers in the back seat of a car often need to use mobile devices such as tablets, laptops, and mobile phones. Therefore, the back seat of a car needs a device that can support mobile office equipment to meet the needs of passengers for working or entertainment.

[0003] Currently, most family cars do not have dedicated work tables in the rear seats. Existing technologies provide some tables for rear passengers, but in these solutions, the tables are either attached to the front seats or integrated with them.

[0004] Because passengers have different heights and body shapes, or even the same passenger needs to adapt to different sitting postures, the height and distance of the tray table need to be adjusted. In existing solutions, since the tray table is attached to the front seat, it needs to be adjusted according to the position of the front seat. If the next passenger adjusts their seat, the rear seat must also be manually adjusted. Furthermore, if a front passenger suddenly adjusts their seat, the equipment attached to the tray table is prone to tipping over or falling, damaging the mobile work equipment.

[0005] To address the aforementioned issues, existing technologies have also provided a solution where the table is foldably installed in the armrest compartment between the two rear seats. However, in these solutions, when the table is unfolded, it either leans towards one side of the seat, making it usable only on the seat on the fixed side; or the table is located in the center, requiring passengers on either side to turn to the table for use, resulting in an uncomfortable seating posture and a poor passenger experience. Summary of the Invention

[0006] In view of this, the present invention provides a rear seat table and a car to solve the problem of limited space and poor passenger experience after the rear seat table is unfolded.

[0007] In a first aspect, the present invention provides a rear seat table for automobiles, comprising a base, a lifting table, and a telescopic table assembly. The base is adapted to be connected to the armrest box of the rear seat of the automobile; the lifting table is connected to the base via a first lifting mechanism; one end of the telescopic table assembly is connected to the lifting table via a rotating mechanism, the telescopic table assembly is adapted to extend toward the side away from the rotating mechanism, and the lifting table and the telescopic table assembly are adapted to be stored in the armrest box.

[0008] Beneficial effects: Because the base is located inside the rear armrest of the car, and the liftable table can be raised and lowered, it can be raised when in use and lowered and stored in the rear armrest when not in use, without taking up additional rear space. Since the telescopic table assembly is connected to the liftable table via a rotating mechanism, it can rotate to be positioned closer to the passenger. Furthermore, the telescopic table assembly can extend away from the rotating mechanism, i.e., towards the passenger. The table can be adjusted in height, angle, and extension length to better accommodate the passenger's height, posture, and usage habits, thus enhancing the passenger experience.

[0009] In one optional embodiment, the rotary mechanism includes a limiting member and a rotary member that are mutually limiting. The limiting member is located at the upper part of the lifting table, and the rotary member is located at the bottom of the telescopic table assembly. The rotary member has a locking position that cooperates with the limiting member and an unlocking position that is disengaged from the limiting member. In the unlocking position, the telescopic table assembly is adapted to rotate.

[0010] Beneficial effects: By incorporating limiting and rotating components, when the table is needed, these components are disengaged from the telescopic table assembly, placing the rotating component in the unlocked position. At this point, the telescopic table assembly can rotate relative to the lifting table, allowing it to be positioned closer to the passenger or in front of them. Once the telescopic table assembly is adjusted to the correct angle, the rotating and limiting components engage to secure the assembly to the lifting table. Using these limiting and rotating components to achieve rotation and locking of the telescopic table assembly improves the reliability of the rear-seat tables.

[0011] In an optional embodiment, the rotating component is a ratchet, and the limiting component is an elastic pawl. In the non-forced state, the limiting component and the rotating component are engaged and in the locked position to prevent the telescopic table assembly from rotating relative to the lifting table. When the telescopic table assembly is manually operated, the elastic engaging force of the pawl on the ratchet is overcome, which allows the ratchet to rotate. The ratchet and pawl are in the unlocked position, and the telescopic table assembly can rotate relative to the lifting table.

[0012] In one optional embodiment, the limiting component includes a limiting sleeve, and the rotating component includes a limiting block. The limiting block and the limiting sleeve are inserted into each other, and an anti-rotation structure is provided between the limiting block and the limiting sleeve.

[0013] Beneficial effects: The use of a limiting sleeve and a limiting block, through a plug-in fit, achieves locking between the rotating part and the limiting part. The structure is simple, and the connection and contact between the limiting block and the limiting sleeve are simple and easy to operate. Simply move the telescopic table assembly in the opposite direction of the plug-in fit to release the fit between the rotating part and the limiting part, thus allowing for rotational adjustment. Then, insert the limiting block into the limiting sleeve in the plug-in direction. Because there is an anti-rotation structure between the limiting block and the limiting sleeve, the rotating part and the limiting part can be locked, making the telescopic table assembly and the lifting table fixed and usable.

[0014] In one alternative embodiment, an elastic reset member is connected between the rotating component and the lifting table, the elastic reset member being adapted to apply an elastic force along the insertion direction to the telescopic table assembly, so that the rotating component is held in the locked position.

[0015] Beneficial effects: By incorporating an elastic reset component, an elastic force is applied to the telescopic table assembly during insertion between the telescopic table assembly and the lifting table. This elastic force, along the insertion direction, brings the telescopic table assembly closer to the lifting table, maintaining a locking relationship between them and improving the table's reliability and stability. Simultaneously, during the insertion of the limiting block on the telescopic table assembly into the lower sleeve on the lifting table, the telescopic table assembly continuously receives the elastic force applied by the elastic reset component. When the limiting block and the limiting sleeve align, the elastic force allows the telescopic table assembly to easily insert into the lifting table, improving the convenience of angle adjustment for the telescopic table assembly.

[0016] In one alternative embodiment, the telescopic table assembly includes a first table and a second table arranged side by side in the same horizontal plane, the first table and the lifting table are rotatably connected, and the second table and the first table are connected by a telescopic rod.

[0017] Beneficial effects: This setup provides two tables for passengers, increasing the usable area; since the second table is connected to the first table by a telescopic rod, the second table can be moved relative to the first table, extending to a position closer to the passenger to provide a more comfortable viewing angle.

[0018] In one alternative embodiment, the first lifting mechanism includes a fixed rod and a lifting rod, which are slidably connected and adjustablely connected by an adjusting member.

[0019] Beneficial effects: The lifting mechanism is achieved by sliding the fixed rod and the lifting rod. The structure is simple, occupies little space, and is suitable for placement in the armrest box of the rear seat of a car.

[0020] In one alternative embodiment, the lifting rod is provided with a threaded hole, and an adjusting bolt is disposed in the threaded hole. The adjusting bolt is adapted to abut against the fixed rod to lock the lifting rod and the fixed rod.

[0021] Beneficial effects: The adjustable bolts allow for easy lifting and lowering adjustments, and ensure reliable locking.

[0022] In one alternative embodiment, the fixing rod is provided with a groove, and the adjusting bolt abuts against the bottom of the groove when locked.

[0023] Beneficial effects: By setting up a sliding groove and adjusting the bolt in conjunction with the sliding groove, the adjusting bolt is always located in the sliding groove when the lifting rod moves up and down along the fixed rod, which plays a guiding and limiting role in the lifting of the lifting rod and improves the moving accuracy of the lifting rod.

[0024] In one alternative implementation, a second lifting mechanism is connected between the base and the bottom of the armrest box.

[0025] Beneficial effects: This design allows for dual adjustment of the table height via the second lifting mechanism, increasing the height adjustment range and further meeting the needs of passengers of greater height and different usage scenarios.

[0026] In one alternative embodiment, the device further includes a top-opening housing adapted to be housed within an armrest box, with a lifting table and a telescopic table assembly housed within the housing, and a base housed within the housing, or the base and the bottom plate of the housing being integrally formed.

[0027] Beneficial effects: With this setup, when the tabletop is not in use, the lifting tabletop and telescopic tabletop components can be stored inside the cabinet, which can protect the various components inside the tabletop.

[0028] In one alternative embodiment, a foldable auxiliary support frame is provided between the base and the lifting table, and the auxiliary support frame and the first lifting mechanism are arranged side by side.

[0029] Beneficial effects: By setting up an auxiliary support frame, the lifting table and the telescopic table assembly located on the lifting table can be provided with auxiliary support, thereby improving the stability and load-bearing capacity of the lifting table and the telescopic table assembly.

[0030] In one alternative embodiment, the auxiliary support frame includes a rotatably connected linkage assembly, one end of which is rotatably connected to the bottom of the lifting table, and the other end of which is rotatably connected to the base.

[0031] Beneficial effects: The auxiliary support frame adopts a linkage assembly, which can adapt to any height adjustment of the first lifting mechanism. The structure is simple, practical and reliable.

[0032] Secondly, the present invention also provides a car, including rear seats and a rear table as described in any of the above technical solutions, with an armrest box provided between adjacent seats; the rear table is located inside the armrest box.

[0033] Since the car includes a rear seat table, which has the same effect as a rear seat table, it will not be elaborated on here. Attached Figure Description

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] The following is combined with Figures 1 to 7 The following describes embodiments of the present invention.

[0046] According to an embodiment of the present invention, a rear seat table for automobiles is provided, comprising a base 1, a lifting table 2, and a telescopic table assembly 3. The base 1 is adapted to be connected to the armrest box of the rear seat of the automobile; the lifting table 2 is connected to the base 1 via a first lifting mechanism 4; one end of the telescopic table assembly 3 is connected to the lifting table 2 via a rotating mechanism 5, and the telescopic table assembly 3 is adapted to extend toward the side away from the rotating mechanism 5; the lifting table 2 and the telescopic table assembly 3 are adapted to be stored in the armrest box.

[0047] Since the base 1 is located inside the rear armrest box of the car, and the lifting table 2 can be raised and lowered, it can be raised when in use under the drive of the first lifting mechanism 4, and lowered and stored in the rear armrest box when not in use, without taking up additional rear space. Because the telescopic table assembly 3 is connected to the lifting table 2 via the rotating mechanism 5, the telescopic table assembly 3 can rotate to a position closer to the passenger. Furthermore, the telescopic table assembly 3 can extend towards the side away from the rotating mechanism 5, i.e., towards the passenger. The table can be adjusted in height, angle, and extension length to better accommodate the passenger's height, posture, and usage habits, thus improving the passenger experience.

[0048] In one embodiment, the rotary mechanism 5 includes a limiting member 501 and a rotary member 502 that are mutually limiting. The limiting member 501 is located on the upper part of the lifting table 2, and the rotary member 502 is located on the bottom of the telescopic table assembly 3. The rotary member 502 has a locking position that cooperates with the limiting member 501 and an unlocking position that is disengaged from the limiting member 501. In the unlocking position, the telescopic table assembly 3 is adapted to rotate.

[0049] By setting a limiting component 501 and a rotating component 502, when the table is needed, the limiting component 501 and the rotating component 502 connected to the telescopic table assembly 3 are disengaged, so that the rotating component 502 is in the unlocked position. At this time, the telescopic table assembly 3 can rotate relative to the lifting table 2 to rotate the telescopic table assembly 3 to the side closer to the passenger or to the front of the passenger. After the telescopic table assembly 3 is adjusted to the correct angle, the rotating component 502 and the limiting component 501 are engaged to fix the telescopic table assembly 3 and the lifting table 2. The use of the limiting component 501 and the rotating component 502 to achieve the rotation and locking of the telescopic table assembly 3 improves the reliability of the rear table.

[0050] In one embodiment, the limiting member 501 includes a limiting sleeve 5011, and the rotating member 502 includes a limiting block 5021. The limiting block 5021 and the limiting sleeve 5011 are inserted into each other, and an anti-rotation structure 504 is provided between the limiting block 5021 and the limiting sleeve 5011.

[0051] The structure employs a limiting sleeve 5011 and a limiting block 5021, which are interlocked to lock the rotating component 502 and the limiting component 501. The structure is simple, and the connection and contact between the limiting block 5021 and the limiting sleeve 5011 are simple and easy to operate. The cooperation between the rotating component 502 and the limiting component 501 can be released simply by moving the telescopic table assembly 3 in the opposite direction of the interlocking, so that it can be used for rotation adjustment. Then, the limiting block 5021 is inserted into the limiting sleeve 5011 in the interlocking direction. Since there is an anti-rotation structure 504 between the limiting block 5021 and the limiting sleeve 5011, the rotating component 502 and the limiting component 501 can be locked, so that the telescopic table assembly 3 and the lifting table 2 are fixed and usable.

[0052] Specifically, when it is necessary to adjust the angle of the telescopic table assembly 3, pull the telescopic table assembly 3 upward. The limiting block 5021 below the telescopic table assembly 3 will disengage from the limiting sleeve 5011 on the lifting table 2 assembly. Thus, the angle can be adjusted by rotating the telescopic table assembly 3. After adjusting to the appropriate angle, align the limiting block 5021 and the limiting sleeve 5011, press down the telescopic table assembly 3, and insert the limiting block 5021 into the limiting sleeve 5011 to lock it and prevent relative rotation between the telescopic table assembly 3 and the lifting table 2.

[0053] In one embodiment, the inner wall of the limiting sleeve 5011 is a polygonal structure, and the outer wall of the limiting block 5021 is a matching polygonal structure. The two are interlocked to form the aforementioned anti-rotation structure 504. In one embodiment, the polygon is hexagonal. It can be understood that the more sides the polygon has, the more adjustable angles the telescopic table assembly 3 can have when rotating.

[0054] Of course, the anti-rotation structure 504 is not limited to the polygonal structure described above. For example, in one embodiment, the inner wall of the limiting sleeve 5011 is provided with a spline groove, and the outer wall of the limiting block 5021 is provided with a spline column, so that the two can achieve anti-rotation after insertion.

[0055] In one embodiment, an elastic reset member 503 is connected between the rotating member 502 and the lifting table 2. The elastic reset member 503 is adapted to apply an elastic force along the insertion direction to the telescopic table assembly 3, so that the rotating member 502 is held in the locked position.

[0056] By setting the elastic reset component 503, when the telescopic table assembly 3 and the lifting table 2 are inserted together, an elastic force can be applied to the telescopic table assembly 3. The elastic force is along the insertion direction, that is, the elastic force brings the telescopic table assembly 3 closer to the lifting table 2, keeping the telescopic table assembly 3 and the lifting table 2 locked together, improving the reliability and stability of the table. At the same time, during the process of the limiting block 5021 on the telescopic table assembly 3 being inserted into the lower sleeve on the lifting table 2, the telescopic table assembly 3 continuously receives the elastic force applied by the elastic reset component 503. When the limiting block 5021 and the limiting sleeve 5011 are aligned, under the action of the elastic force, the telescopic table assembly 3 can easily be inserted into the lifting table 2, improving the convenience of angle adjustment of the telescopic table assembly 3.

[0057] In one embodiment, the elastic reset member 503 includes a spring. When the telescopic table assembly 3 and the lifting table 2 are not connected by the elastic reset member 503, the telescopic table assembly 3 can be lifted, detached from the lifting table 2, and placed in other positions to provide support. Mobile devices such as office or entertainment devices can be placed on the lifting table 2. When the telescopic table assembly 3 and the lifting table 2 are connected by the elastic reset member 503, the elastic reset member 503 also serves as a guide, facilitating quick positioning and insertion between the limiting block 5021 of the telescopic table assembly 3 and the limiting sleeve 5011 on the lifting table 2, thereby improving adjustment efficiency.

[0058] In one embodiment, the telescopic table assembly 3 includes a first table 301 and a second table 302 arranged side by side in the same horizontal plane. The first table 301 and the lifting table 2 are rotatably connected, and the second table 302 and the first table 301 are connected by a telescopic rod 303.

[0059] This arrangement provides two tables for passengers, increasing the usable area. Since the second table 302 and the first table 301 are connected by a telescopic rod 303, the second table 302 can move relative to the first table 301, allowing the second table 302 to extend closer to the passenger, thus providing a more comfortable viewing angle for the passenger.

[0060] In one embodiment, the first lifting mechanism 4 includes a fixed rod 401 and a lifting rod 402, which are slidably connected and adjustablely connected by an adjusting member 403.

[0061] The lifting mechanism is achieved by the sliding cooperation of the fixed rod 401 and the lifting rod 402. It has a simple structure, occupies little space, and is suitable for placement in the armrest box of the rear seat of a car.

[0062] In one embodiment, the lifting rod 402 is provided with a threaded hole, and an adjusting bolt is provided in the threaded hole. The adjusting bolt is adapted to abut against the fixed rod 401 to lock the lifting rod 402 and the fixed rod 401.

[0063] The adjustable bolts allow for easy height adjustment and reliable locking.

[0064] In one embodiment, the fixing rod 401 is provided with a sliding groove 404, which abuts against the bottom of the sliding groove 404 when the adjusting bolt is locked.

[0065] By setting a slide groove 404 and adjusting the bolt in cooperation with the slide groove 404, the adjusting bolt is always located in the slide groove 404 when the lifting rod 402 moves up and down along the fixed rod 401. This plays a guiding and limiting role in the lifting of the lifting rod 402 and improves the moving accuracy of the lifting rod 402.

[0066] In one embodiment, the adjusting bolt is located on the outside of the lifting rod 402 for ease of operation.

[0067] In one embodiment, two first lifting mechanisms 4 are provided, and the two lifting mechanisms are spaced apart along the length direction of the lifting table 2. In another embodiment, two first lifting mechanisms 4 are provided, and they are spaced apart along the width direction of the lifting table 2. In this case, auxiliary support frames 8 can be arranged side by side along the length direction of the lifting table 2. The auxiliary support frames 8 will be described in detail below.

[0068] In one embodiment, a second lifting mechanism 6 is connected between the base 1 and the bottom of the armrest box.

[0069] This configuration allows for dual adjustment of the table height via the second lifting mechanism 6, increasing the height adjustment range and further meeting the needs of passengers of greater height and different usage scenarios.

[0070] In one embodiment, the second lifting mechanism 6 includes a lead screw and nut pair and a drive motor 601 that drives the lead screw or nut to rotate. The drive motor 601 is fixed to the vehicle body 9. The second lifting mechanism 6 is implemented using a lead screw and nut pair, which has self-locking properties, can maintain the current position of the lifting table 2, prevent it from falling, improve the reliability of the table, and also protect the items placed on the table. In one embodiment, the drive motor 601 is a brushless motor. The drive motor 601 is connected to the nut, driving the nut to rotate. The top of the lead screw is connected to the base 1. When the nut rotates, it drives the lead screw to rise and fall, thereby driving the base 1 and the lifting table 2 and the telescopic table assembly 3 on it to rise and fall.

[0071] In one embodiment, the device further includes a top-opening box 7, which is adapted to be stored inside an armrest box. The lifting table 2 and the telescopic table assembly 3 are disposed inside the box 7, and the base 1 is disposed inside the box 7, or the base 1 and the bottom plate of the box 7 are integrally disposed.

[0072] With this configuration, when the tabletop is not in use, the lifting tabletop 2 and the telescopic tabletop assembly 3 can be stored inside the housing 7, and the housing 7 can protect the various components inside the tabletop.

[0073] In one embodiment, a foldable auxiliary support frame 8 is provided between the base 1 and the lifting table 2, and the auxiliary support frame 8 and the first lifting mechanism 4 are arranged side by side.

[0074] By setting up the auxiliary support frame 8, the lifting table 2 and the telescopic table assembly 3 located on the lifting table 2 can be provided with auxiliary support, thereby improving the stability and load-bearing capacity of the lifting table 2 and the telescopic table assembly 3.

[0075] In one embodiment, the auxiliary support frame 8 includes a rotatably connected linkage assembly, one end of which is rotatably connected to the bottom of the lifting table 2, and the other end of which is rotatably connected to the base 1.

[0076] The auxiliary support frame 8 uses a linkage assembly, which can adapt to any height adjustment of the first lifting mechanism 4. The structure is simple, practical and reliable.

[0077] According to an embodiment of the present invention, another aspect provides a car, including rear seats and a rear seat table as described in any of the above technical solutions, with an armrest box provided between adjacent seats; the rear seat table is disposed in the armrest box.

[0078] Since the car includes a rear seat table, which has the same effect as a rear seat table, it will not be elaborated on here.

[0079] In use, opening the armrest box allows the lifting table 2 to be raised via the first lifting mechanism 4, with the telescopic table assembly 3 rising along with it. When the lifting table 2 or telescopic table assembly 3 reaches the desired height, tightening the adjusting bolts secures the lifting table 2. If the first lifting mechanism 4's maximum height is insufficient for passenger needs, the second lifting mechanism 6 can be electrically activated to raise the lifting table 2 and telescopic table assembly 3 to the appropriate position, completing height adjustment. Pulling the telescopic table assembly 3 upwards adjusts the second table 302 to the desired angle. Lowering the telescopic table assembly 3 locks it in place through the engagement of the limiting block 5021 and the limiting sleeve 5011, as well as the anti-rotation structure 504, completing angle adjustment. Extending the telescopic rod 303 moves the second table 302 to the desired position, completing table adjustment. Passengers can freely adjust the table's height, width, and angle, making efficient use of space.

[0080] When the table is not in use, retract the second table 302, rotate the telescopic table assembly 3 to adjust the first table 301 and the second table 302 to overlap with the lifting table 2, unlock the adjusting bolt, lower the lifting table 2 and the telescopic table assembly 3 so that they are stored in the housing 7, start the motor of the second lifting mechanism 6 to lower the housing 7 so that the housing 7 is stored in the armrest box. When the table is retracted, the top cover of the tabletop is level with or lower than the upper surface of the seat. Cover the armrest box with the cover so as not to obstruct the passenger's seating and to prevent collisions with the passenger. Furthermore, a cover plate can be used for concealment, and a cloth or cushion of the same material as the seat can be used for covering.

[0081] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
