Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, specifically to a small table structure for automobiles. Background Technology

[0002] With the continuous upgrading of automobiles, cars are no longer just a means of transportation, but are gradually transforming into mobile homes and mobile offices. They are also developing towards greater technological sophistication, intelligence, and practicality, offering drivers and passengers more functions and features to provide a more complete riding experience and a more comfortable environment. These new application scenarios have spurred increasing functional demands for car seats, giving rise to the need for small tables. While driving, different people have different needs—whether it's resting, reading or working, or communicating with other passengers—and adjustable small tables provide excellent assistance, allowing passengers to place snacks, books, laptops, mobile phones, drinks, and other items.

[0003] Existing height-adjustable tables generally include a housing with a storage slot and a table assembly. The table assembly usually uses a cylinder and push rod structure to drive the table assembly out of the storage slot of the housing. However, this driving method has insufficient stroke, which can easily cause the table assembly to not move up into place, affecting the user experience. Summary of the Invention

[0049] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0050] Example 1

[0051] Please see Figures 1 to 12 This embodiment provides a car tray structure, including: a housing 1 with a receiving groove 2; a base 3 slidably connected in the receiving groove 2 in a vertical direction; a tray assembly 4 disposed on the base 3; and a lifting assembly including a pulley 14, a drive member, and a locking rope 17. The pulley 14 and the base 3 are both disposed on the housing 1. The pulley 14 is located above the base 3, and the drive member is located below the pulley 14. One end of the locking rope 17 is connected to the base 3 or the tray assembly 4, and the other end passes around the pulley 14 and is connected to the drive member. The drive member is used to wind up the locking rope 17 and drive the base 3 to move upward so as to push the tray assembly 4 out of the receiving groove 2.

[0052] It should be noted that the tabletop assembly 4 can be stored in the receiving slot 2.

[0053] In this embodiment, when the tabletop assembly 4 is needed, the locking rope 17 can be wound up by the drive component. The actual height to which the tabletop assembly 4 can be pushed out can be determined as needed. The locking rope 17 is connected to the base 3 or the tabletop assembly 4, and the locking rope 17 applies an upward force to the base 3 or the tabletop assembly 4, causing the base 3 to move upward, thereby pushing the tabletop assembly 4 out of the receiving slot 2 for use. When storing, the tabletop assembly 4 and the base 3 can be pushed into the receiving slot 2. By using the method of winding up the locking rope 17, compared with the method of using a cylinder and push rod structure, the stroke of driving the tabletop assembly 4 to move upward is increased, ensuring that the tabletop assembly 4 moves into place for convenient use by the user, improving the user experience. Moreover, this method has a simpler structure, is more convenient to operate, reduces the space occupation rate, facilitates the arrangement, and improves the interior appearance quality.

[0054] Example 2

[0055] As a further improvement to Example 1, such as Figure 1 , Figure 8 and Figure 9As shown, the driving component includes a first roller 15 and a second roller 16; both the first roller 15 and the second roller 16 are rotatably connected to the housing 1; the first roller 15 is provided with a first winding portion and a second winding portion in sequence along its axial direction; a coil spring 18 is wound on the second roller 16, and the outer end of the coil spring 18 is connected to the first winding portion; a locking rope 17 is connected to the second winding portion.

[0056] In this embodiment, as Figure 8 As shown, Figure 8 With the base 3 positioned at the bottom of the receiving groove 2 and the tabletop assembly 4 located within the receiving groove 2, a portion of the coil spring 18 is wound around the first winding portion of the first roller 15 and is in a stretched state. When it is necessary to push the tabletop assembly 4 out of the receiving groove 2, under the elastic torque of the coil spring 18, the coil spring 18 recovers its position by winding from the first winding portion to the second roller 16, causing the first roller 15 to rotate counterclockwise. This, in turn, winds the locking rope 17 onto the second winding portion, shortening the length of the extended locking rope 17. This, in turn, pulls the base 3 upward to push the tabletop assembly 4 out of the receiving groove 2 for use. Figure 9 As shown, Figure 9 The position of the base 3 when the tabletop assembly 4 is pushed out of the receiving groove 2; conversely, when the tabletop assembly 4 is pushed into the receiving groove 2, the locking rope 17 wound in the second winding part is subjected to an upward pulling force, which in turn drives the first roller 15 to rotate clockwise. At the same time, the first winding part rotates clockwise and overcomes the torque of the coil spring 18, winding a part of the coil spring 18 around the first winding part. At this time, the coil spring 18 is in a stretched state, so as to provide the driving force to push the tabletop assembly 4 out of the receiving groove 2. The tabletop assembly 4 is driven by the first roller 15 and the second roller 16 in conjunction with the coil spring 18, so that the tabletop assembly 4 moves up slowly and smoothly, providing a better user experience. It does not require electricity and is driven by electronic control. It has a wide range of applications, simple structure, convenient operation, and small space occupation. In addition, the first winding part and the second winding part are staggered to prevent the coil spring 18 and the locking rope 17 from getting tangled together during use.

[0057] Specifically, the second winding section is located outside the first winding section, which facilitates the connection and winding of the locking rope 17.

[0058] Based on the above embodiments, in a preferred embodiment, such as Figure 8 and Figure 9 As shown, the first winding part is a turntable, the coil spring 18 is connected to the outer periphery of the turntable, and the diameter of the turntable is larger than the diameter of the second roller 16.

[0059] In this embodiment, by using a turntable with a larger diameter to connect the coil spring 18, the excessive bending arc of the coil spring 18 caused by long-term stretching through the first winding part is avoided, which leads to the failure of the elasticity of the coil spring 18, thereby improving its service life and reducing the driving force required to stretch the coil spring 18 when the drive base 3 moves down.

[0060] Based on the above embodiments, in a preferred embodiment, the second winding portion is provided with a storage groove for winding the locking rope 17 around its outer periphery.

[0061] In this embodiment, a storage groove is provided around the outer periphery of the second winding part along its axial direction. When the drive base 3 moves upward, the locking rope 17 is stored in the storage groove to prevent the locking rope 17 from shifting during the storage process and to improve stability.

[0062] Based on the above embodiments, in a preferred embodiment, a rotary damper is provided inside the housing 1, and the first roller 15 or the second roller 16 is meshed with the rotary damper through a gear assembly.

[0063] In this embodiment, by setting a rotation damper, the rotation speed of the first roller 15 or the second roller 16 is limited, so that the table panel assembly 4 is driven to rise slowly and smoothly, avoiding injury to the user caused by excessive rising speed, and avoiding damage to other parts caused by excessive rising speed of the table panel assembly 4, thereby improving the user experience.

[0064] Based on the above embodiments, in a preferred embodiment, such as Figures 1 to 3 As shown, the tabletop assembly 4 is rotatably connected to the base 3 via the adjustment assembly 5 in the vertical direction; the adjustment assembly 5 has a first state in which the tabletop assembly 4 is adjusted to align with the receiving groove 2 so as to be pushed into or stored in the receiving groove 2, and a second state in which the tabletop assembly 4 is adjusted to be placed horizontally when the tabletop assembly 4 is pushed out of the receiving groove 2.

[0065] It should be noted that when the adjustment component 5 is adjusted to the first state, the vertical projection of the tabletop component 4 falls into the receiving groove 2.

[0066] In this embodiment, the tabletop assembly 4 is connected to the base 3 via the adjusting component 5. The tabletop assembly 4 can be adjusted to a first state via the adjusting component 5, allowing it to rotate on the base 3 to align with the receiving groove 2. This enables the tabletop assembly 4 to slide vertically into the receiving groove 2, saving space and improving aesthetics. In practical applications, it can be hidden within the armrest. When in use, the tabletop assembly 4 is pushed out from the receiving groove 2, and the adjusting component 5 is then adjusted to a second state, allowing the tabletop assembly 4 to be placed horizontally for use. During use, the position can also be adjusted by rotating the adjusting component 5 on the base 3, increasing the flexibility of adjustment to meet user needs and improve the user experience.

[0067] Based on the above embodiments, in a preferred embodiment, such as Figures 1 to 3As shown, the adjustment assembly 5 includes a connector 51 and a first support 52; the connector 51 is vertically disposed on the base 3 and rotatably connected to the base 3; the first support 52 is dampedly hinged to the end of the connector 51 away from the base 3, and the first support 52 rotates on the connector 51 to be perpendicular or parallel to the connector 51; the table assembly 4 is disposed on the first support 52.

[0068] It should be noted that when the tabletop assembly 4 is placed horizontally, it is located on top of the first support member 52.

[0069] In this embodiment, the connector 51 cooperates with the first support 52. When the tabletop assembly 4 needs to be stored, the first support 52 is rotated to be parallel to the connector 51, and the connector 51 is rotated until the tabletop assembly 4 is aligned with the receiving groove 2. That is, the adjustment component 5 is in the first state, so that the tabletop assembly 4 can be pushed into the receiving groove 2. After the tabletop assembly 4 is pushed out of the receiving groove 2, the connector 51 is rotated to an appropriate position, and the first support 52 is rotated to a preset angle with the connector 51. Preferably, the first support 52 is rotated to be perpendicular to the connector 51. At this time, the first support 52 is horizontal, that is, the adjustment component 5 is in the second state, so that the tabletop assembly 4 is placed horizontally for easy use. In addition, the connector 51 and the first support 52 are damped hinged, which can improve the stability during rotation and enable hovering use when rotated to any angle, thus improving the flexibility of use.

[0070] Specifically, the tabletop assembly 4 is located at the end of the first support member 52 away from the connector 51.

[0071] Based on the above embodiments, in a preferred embodiment, such as Figure 4 and Figure 5 As shown, the tabletop assembly 4 is rotatably connected to the first support member 52 via the pivot assembly 6. A limiting component is provided between the tabletop assembly 4 and the first support member 52. The limiting component is used to limit the tabletop assembly 4 to rotate to a first position where it is parallel to and overlaps with the first support member 52 in its length direction, and to rotate to a second position where it is parallel to and overlaps with the first support member 52 in its length direction in the extending direction of the first support member 52.

[0072] In this embodiment, when the tabletop assembly 4 is placed horizontally by the first support member 52, it is limited by the limiting component. The tabletop assembly 4 is rotated to a second position where its length direction is aligned with the extension direction of the first support member 52 and its length direction is aligned with the first support member 52, so as to facilitate user use and prevent shaking during use. When it is necessary to retract the tabletop assembly 4, it can be rotated to a first position where its length direction is parallel to and overlaps with the first support member 52, so as to store it in the receiving slot 2. The tabletop assembly 4 is rotatably connected to the first support member 52 through the rotating shaft assembly 6, which improves the smoothness of rotation. The tabletop assembly 4 can be rotated within the limiting range of the limiting component to adjust it to a comfortable position for user use, thereby improving user experience and adjustment flexibility.

[0073] Based on the above embodiments, in a preferred embodiment, such as Figure 4 and Figure 5 As shown, the limiting component includes a first limiting block 7 and a first limiting part 8; the first limiting block 7 is disposed on the side of the first support member 52 facing the tabletop assembly 4; the first limiting part 8 is disposed on the side of the tabletop assembly 4 facing the first support member 52; the first limiting part 8 is provided with an arc-shaped limiting groove 9 around the axis of the rotating shaft assembly 6, and the first limiting block 7 is adapted to slide in the arc-shaped limiting groove 9; when the first limiting block 7 abuts against one end of the arc-shaped limiting groove 9, the tabletop assembly 4 is parallel to and overlaps with the first support member 52 in its length direction; when the first limiting block 7 abuts against the other end of the arc-shaped limiting groove 9, the tabletop assembly 4 is parallel to the first support member 52 in its extension direction and in its length direction.

[0074] In this embodiment, the first limiting block 7 on the first support member 52 cooperates with the first limiting part 8 on the tabletop assembly 4, so that the first limiting block 7 always rotates within the arc-shaped limiting groove 9 and is limited when it abuts against both ends of the arc-shaped limiting groove 9. This allows the tabletop assembly 4 to be rotated parallel to and overlap with the first support member 52 during storage, and the tabletop assembly 4 to be rotated in the extending direction of the first support member 52 and parallel to the first support member 52 during use, thereby improving the user experience.

[0075] Based on the above embodiments, in a preferred embodiment, such as Figure 2 and Figure 3 As shown, the adjustment component 5 also includes a second support member 53; the first support member 52 has a slide groove 54 on the side that rotates in the horizontal direction, and the slide groove 54 is arranged along the length direction of the first support member 52; one end of the second support member 53 is slidably connected to the slide groove 54 by a pin, and the other end is hinged to the connector 51.

[0076] In this embodiment, a triangular structure is formed by setting a second support member 53 between the first support member 52 and the connecting member 51. When the first support member 52 rotates to a horizontal position, it is supported by the second support member 53, which improves stability and support strength. Furthermore, when the first support member 52 rotates on the connecting member 51, the second support member 53 slides adaptively in the slide groove 54 through the pin, avoiding jamming.

[0077] Based on the above embodiments, in a preferred embodiment, such as Figure 11 and Figure 12 As shown, the second support member 53 has a triangular support member 55 on the side opposite to the first support member 52. When the first support member 52 rotates to be perpendicular to the connector 51, the triangular support member 55 abuts against the housing 1.

[0078] In this embodiment, a triangular support 55 is provided on the second support member so that when the first support member 52 rotates to be perpendicular to the connector 51, the triangular support 55 abuts against the shell to provide support force, thereby further improving the support strength, so as to facilitate the use of the table assembly 4 and improve its service life.

[0079] Specifically, the connector 51 is provided with a shock-absorbing pad corresponding to the second support 53. When the first support 52 and the connector 51 are parallel, the shock-absorbing pad abuts against the second support 53, which plays the role of shock absorption and noise reduction.

[0080] Specifically, such as Figure 3 As shown, the first support member 52 has a slot, and a fixing plate is detachably connected to the first support member 52 at the slot. The fixing plate covers the slot, and an opening communicating with the slot is provided on the fixing plate along the length direction of the first support member 52. The width of the opening is adapted to the width of the second support rod. The fixing plate and the slot together form a sliding groove 54. Both ends of the first support member 52 are provided with pins, and the first support member 52 is slidably connected in the sliding groove 54 by the pins. The sliding groove 54 is formed by the fixing plate and the slot, which facilitates installation and disassembly.

[0081] Based on the above embodiments, in a preferred embodiment, such as Figure 10 As shown, a second limiting block 10 is provided on the periphery of the connector 51, and a second limiting part 11 is provided on the base 3; the second limiting part 11 is located on the rotation path of the second limiting block 10 and is used to abut against the second limiting block 10 for limiting.

[0082] In this embodiment, the second limiting block 10 on the connector 51 cooperates with the second limiting part 11 on the base 3. When the connector 51 rotates to the point where the second limiting block 10 abuts against the second limiting part 11, the first support member 52 is parallel to the direction of the armrest inside the car, so that the user can use the table assembly 4 and avoid shaking during use.

[0083] Based on the above embodiments, in a preferred embodiment, the connector 51 is hinged to the first support 52 via a first damping hinge.

[0084] In this embodiment, the connector 51 is hinged to the first support 52 via a first damping hinge, which allows the first support 52 to rotate slowly and smoothly, avoiding excessive rotation speed due to gravity, which could damage the connection or injure the user. It can also be suspended when rotated to any angle, improving service life and user experience.

[0085] Based on the above embodiments, in a preferred embodiment, such as Figure 1 and Figure 2 As shown, the tabletop assembly 4 includes a first tabletop 41 and a second tabletop 42. The first tabletop 41 is mounted on the first support member 52. The second tabletop 42 is dampedly hinged to the first tabletop 41, and the second tabletop 42 can rotate around the hinge to maintain a preset angle with the first tabletop 41.

[0086] In this embodiment, the table assembly 4 consists of a first table 41 and a second table 42, such that the second table 42 is kept suspended when rotated on the first table 41 to a preset angle for use. The specific angle can be selected according to actual needs, and the preset angle can be any angle. Preferably, when in use, the second table 42 can be flipped to be parallel to the first table 41 to increase the usable area for use. After use, it can be flipped to overlap to reduce the area, making it easy to fold and store, reducing the space occupied, and thus improving the space utilization rate.

[0087] Specifically, the first tabletop 41 is hinged to the second tabletop 42 via a second damping hinge 43. The second damping hinge 43 allows the second tabletop 42 to rotate slowly and smoothly, enabling it to hover at any angle. This prevents the tabletop from rotating too quickly due to gravity, which could damage the connection or injure the user, thus improving its lifespan and user experience.

[0088] Based on the above embodiments, in a preferred embodiment, such as Figure 1 , Figure 6 and Figure 7 As shown, the car table structure also includes a locking tongue assembly 12, which is disposed on the housing 1. The adjustment assembly 5 is provided with a locking groove 13 corresponding to the locking tongue assembly 12. The locking tongue assembly 12 has a locked state that engages with the locking groove 13, and an unlocked state that disengages from the locking groove 13. When the table assembly 4 is stored in the receiving groove 2, the locking tongue assembly 12 engages with the locking groove 13.

[0089] In this embodiment, a locking tongue assembly 12 is used to engage with the snap-fit ​​groove 13 when the tabletop assembly 4 is housed in the receiving groove 2. That is, the locking tongue assembly 12 is in the locked state, locking the tabletop assembly 4 in the receiving groove 2, preventing the tabletop assembly 4 from moving upward under the action of the lifting assembly, and ensuring stability. When the tabletop assembly 4 needs to be used, the locking tongue assembly 12 can be adjusted to the unlocked state and separated from the snap-fit ​​groove 13. The tabletop assembly 4 moves upward under the driving force of the driving component. In particular, when the driving component is a coil spring 18, it works with the coil spring to realize the automatic upward movement of the tabletop assembly 4, improving the user experience.

[0090] Specifically, the snap-fit ​​groove 13 is provided on the first support member 52.

[0091] Specifically, such as Figure 6 As shown, the latch assembly 12 includes a base and a latch, which is adapted to the locking groove 13. The latch is retractably mounted on the base, which has a button. When the button is pressed, the latch retracts towards the base and disengages from the locking groove 13, meaning the latch assembly 12 is in the unlocked state. When the tabletop assembly 4 is retracted into the receiving groove 2, the latch extends and engages with the locking groove 13, meaning the latch assembly 12 is in the locked state, locking the tabletop assembly 4 within the receiving groove 2. When needed, pressing the button disengages the latch from the locking groove 13, and the tabletop assembly 4 moves upward under the action of the driving component. The latch assembly 12 can employ existing related technologies, which will not be described in detail here.

[0092] Based on the above embodiments, in a preferred embodiment, such as Figure 1 As shown, a first limiting member 19 is provided on the housing 1 below the base 3, and a plurality of first rubber pads 20 are provided on the top of the first limiting member 19 for cooperating with the base 3 to abut and limit the position.

[0093] In this embodiment, by setting the first limiting member 19 to limit the movement of the base 3 below, the base 3 is prevented from moving too far when it descends, and the first rubber pad 20 is used to reduce shock and noise, thereby improving the user experience.

[0094] Based on the above embodiments, in a preferred embodiment, a second limiting member is provided on the housing 1 above the base 3, and the bottom of the second limiting member is provided with a plurality of second rubber pads for cooperating with the base 3 to abut and limit the position.

[0095] In this embodiment, by setting a second limiting member below the base 3, the movement distance of the base 3 is prevented from being too large when it moves upward, and the second rubber pad is used to reduce shock and noise, thereby improving the user experience.

[0096] Based on the above embodiments, in a preferred embodiment, such as Figure 1 and Figure 9 As shown, a linear damper 21 is provided on the housing 1 below the base 3 to abut against the base 3 as it slowly descends.

[0097] In this embodiment, by setting a linear damper 21 below the base 3, the speed of the base 3 descending to contact the linear damper 21 is stable and slow, avoiding direct contact with the bottom of the receiving groove 2 and thus preventing damage, thereby improving the user experience.

[0098] Based on the above embodiments, in a preferred embodiment, such as Figure 1 and Figure 10 As shown, the inner sidewall of the receiving groove 2 is provided with a first guide rail 22 and two second guide rails 23 in the vertical direction. The two second guide rails 23 are arranged symmetrically, and the first guide rail 22 is located between the two second guide rails 23. The base 3 is in sliding fit with the first guide rail 22 and the second guide rail 23.

[0099] In this embodiment, by setting a first guide rail 22 and two second guide rails 23, which are arranged in a triangular pattern in the plane, the stability during the lifting process is improved. The two second guide rails 23 play a guiding and limiting role and reduce swaying. By using the first guide rail 22 to further cooperate, the guiding and limiting role and the swaying reduction role are further enhanced, thereby improving the overall stability.

[0100] Specifically, such as Figure 10 As shown, the base 3 is provided with a first guide groove that is adapted to slide and engage with the first guide rail 22. The first guide rail 22 slides in conjunction with the first guide groove to improve stability. Preferably, the first guide groove can be a T-shaped groove to further improve stability.

[0101] Specifically, such as Figure 10 As shown, the second guide rail 23 is provided with a second guide groove along the vertical direction, and the base 3 is provided with a guide rib that is adapted to slide and cooperate with the second guide groove. The guide rib cooperates with the second guide rail 23 to slide and guide and limit, while further improving stability and reducing shaking.

[0102] Specifically, pulley component 14 is a pulley, which is rotatably mounted on housing 1.

[0103] In one embodiment, the connection position of the locking rope 17 is not specifically limited. The locking rope 17 can be connected to the base 3, the table assembly 4, or the adjustment assembly 5. The specific connection can be selected according to actual needs. Preferably, the locking rope 17 is connected to the base 3 to improve stability during movement and increase the rising height of the table assembly 4.

[0104] The specific working principle provided in this embodiment is as follows: When the tabletop assembly 4 needs to be used, pressing the button on the latch assembly 12 causes the latch to disengage from the locking groove 13 and unlock. Under the elastic torque of the coil spring 18, the coil spring 18 recovers from the first winding part to the second roller 16, and drives the first roller 15 to rotate, thereby winding the locking rope 17 onto the second winding part. As a result, the length of the extended locking rope 17 becomes shorter, which in turn pulls the base 3 upward to abut against the second limiting member, and then rotates the connecting member 51. To position the tabletop 41, rotate the first support member 52 to a horizontal position, preferably aligned with the armrest. Then, flip the second tabletop 42 to a position parallel to the first tabletop 41 or another suitable position and hold it there. Simultaneously, rotate the first tabletop 41 to a suitable position for use. For storage, flip the second tabletop 42 to overlap with the first tabletop 41. Then, rotate the first tabletop 41 to a position parallel to and overlapping with the first support member 52. Next, rotate the first support member 52 to a position parallel to the connecting member 51. Finally, the tabletop assembly 4 and the base are... 3. Pushing the locking rope 17 into the receiving groove 2, the locking rope 17 wound in the second winding part is pulled upward, which in turn drives the first roller 15 to rotate in the opposite direction. At the same time, the first winding part rotates in the opposite direction and overcomes the torque of the coil spring 18, winding a part of the coil spring 18 around the first winding part until the base 3 abuts against the first limiting member 19 and the locking tongue is engaged in the locking groove 13, completing the storage. At this time, the coil spring 18 is in a stretched state, so as to provide the driving force to push the table assembly 4 out of the receiving groove 2. By adopting the method of winding the locking rope 17, compared with the method of using a cylinder and push rod structure, the stroke of driving the table assembly 4 to move upward is increased, ensuring that the table assembly 4 moves upward into place for convenient use by the user, improving the user experience. Moreover, this method has a simpler structure, is more convenient to operate, reduces the space occupation rate, facilitates the arrangement, improves the interior appearance quality, and solves the technical problem that the existing lifting small table uses a cylinder and push rod structure to drive the table assembly 4, which has insufficient stroke and easily leads to the table assembly 4 not moving upward into place, affecting the user experience.

[0105] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
