Description

Technical Field

[0001] This invention belongs to the field of automotive parts technology and relates to an adjustable vehicle tray table. Background Technology

[0002] Car tray tables, as a convenient in-vehicle accessory, are widely used in various vehicles, especially for long-distance travel or family trips, providing a convenient platform for placing food, books, or other small items. Currently, some car models have tray tables designed into the center console, allowing users to pull them out from the armrest or center console for use and push them back into the center console when not in use to keep the interior tidy and maximize space utilization.

[0003] Unlike the small tables set on the back of the seat, the small tables set in the armrests or armrest boxes are located on the side of the passenger. Therefore, these small tables need to be adjustable to the left and right. Currently, there are some small tables that can be adjusted laterally (left and right). The small table can slide relative to the base to change its relative position with the passenger, thereby adapting to passengers of different body types and usage habits.

[0004] For example, an invention patent with application number CN201710244410.4, entitled "A Multifunctional Tabletop and Chair Armrest," describes a multifunctional tabletop that can slide forward, backward, left, and right after being flattened to adapt to different usage scenarios. However, this type of small tabletop has obvious defects: it lacks an effective positioning and locking mechanism when the panel is retracted, and it lacks the supporting force to maintain its unfolded state when the panel is unfolded, failing to form a stable load-bearing plane, which seriously affects the reliability of actual use and the user experience. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the prior art by proposing an adjustable vehicle tray table.

[0006] The objective of this invention can be achieved through the following technical solution: a car tray with adjustable function, comprising:

[0008] A locking member, which is movably mounted in the locking groove, has a travel position including a locked position and an unlocked position;

[0009] When the locking member is in the locking position, the locking member is locked with the other one of the base plate and the table plate to limit the table plate from sliding relative to the base plate.

[0010] When the locking member is in the unlocking position, the locking member is separated from the other one of the base plate and the table plate to allow the table plate to slide relative to the base plate.

[0011] An unlocking member movably mounted in the mounting slot, the unlocking member being in linkage connection with the locking member, the unlocking member being capable of driving the locking member to move by itself, the position of the locking member being determined by the position of the unlocking member.

[0012] Preferably, the sliding groove part is provided with a limiting tooth groove arranged as a rack structure extending along the sliding direction of the table plate, and the locking member is provided with a locking tongue; when the locking member is in the locking position, the locking tongue is engaged with the limiting tooth groove to limit the movement of the table plate.

[0013] Preferably, the sliding groove part is arranged as a groove structure extending along the sliding direction of the table plate, the sliding block part is arranged as a convex structure matching the cross-sectional shape of the sliding groove part, and the limiting tooth groove is arranged on the side surface of the sliding groove part; when the locking member is in the locking position, the locking tongue protrudes from the side surface of the sliding block part.

[0015] When the unlocking member moves, the first driving bevel surface pushes the first force receiving bevel surface to drive the locking member to move towards the unlocking position.

[0016] When the unlocking member moves reversely, the second driving bevel surface pushes the second force receiving bevel surface to drive the locking member to move towards the locking position.

[0017] Preferably, the force receiving part is slidably arranged in the bevel groove part, and the length of the force receiving part is greater than the length of the bevel groove part.

[0018] Preferably, the locking groove comprises two guide grooves extending in the same direction, the extension direction of the guide grooves being the sliding direction of the locking member, and the locking member further comprises two guide portions respectively located at the two ends of the force receiving portion, the two guide portions being in sliding connection with the two guide grooves respectively, and the guide portions can only slide in the extension direction of the guide grooves.

[0019] Preferably, a locking spring is further arranged, one end of the locking spring being connected with the unlocking member and the other end being connected with the sliding block portion, and the locking spring applies an elastic force on the locking member through the unlocking member to make the locking member tend to the locking position.

[0020] Preferably, the table board cover is arranged on the base plate, one of the table board and the base plate is provided with a stroke limiting groove, and the other is provided with a stroke limiting block, the stroke limiting block being slidably arranged in the stroke limiting groove and limiting the maximum sliding stroke of the table board.

[0021] Preferably, a folding connecting member, a movable connecting member and a lifting connecting member are further arranged, the movable connecting member being in sliding connection with the lifting connecting member, the sliding direction of the movable connecting member being perpendicular to the sliding direction of the table board, the folding connecting member being hingedly connected with the movable connecting member, and the base plate being fixedly connected with the folding connecting member.

[0022] Preferably, the lifting connecting member is fixedly provided with a coil spring, the coil spring being connected with the movable connecting member, the coil spring always applying an elastic force on the movable connecting member to make the movable connecting member tend to the initial position, the folding connecting member is provided with a clamping tooth, the lifting connecting member is provided with a rack portion, and when the folding connecting member is rotated to the position in which the table board is flat, the clamping tooth is engaged with the rack portion to limit the sliding of the movable connecting member.

[0023] Compared with the prior art, the present application has the following advantages:

[0024] 1. The table board can slide leftward and rightward relative to the base plate to adjust the position, and the stable limiting self-locking mechanism can be formed through the unlocking member and the locking member, the table board has the positioning locking mechanism after being adjusted to the position, and the stability and reliability during use are ensured.

[0025] 2. The limiting tooth groove is arranged on the side surface of the sliding groove portion, the locking tongue protrudes from the side surface of the sliding block portion, the side surface of the sliding groove portion and the side surface of the sliding block portion are arranged in face-to-face correspondence, the locking tongue can move laterally (i.e. move relative to the width direction of the sliding groove portion) to be engaged with the limiting tooth groove on the side surface to be locked, and this lateral locking mechanism can provide additional locking force and stability.

[0026] 3. Ingeniously utilizing the slope driving mechanism, passengers can easily operate the unlocking piece through natural arm movements (left and right directions) without trying to directly drive the locking piece from the front and rear directions, thus improving the comfort and convenience of operation. Through the precise matching between the slopes, the locking and unlocking of the table board can be realized by simply pushing the unlocking piece left and right, thus simplifying the operation steps and improving the user experience.

[0027] 4. The two guide grooves extend along the same direction, i.e. the front and rear directions. Each guide part is in sliding connection with a guide groove, which means that the guide part can only slide along the extension direction of the guide groove and cannot move along the sliding direction of the table board, because the width of the guide groove is consistent with the width of the guide part, so that the locking piece only has the freedom in the front and rear directions.

[0028] 5. The locking spring is designed to apply a continuous elastic force to the unlocking piece, which is transmitted to the locking piece through the unlocking piece, so that it tends to return to the locking position. When there is no external force (i.e. the passenger does not operate the unlocking piece), the locking spring will automatically push the unlocking piece, thereby driving the locking piece into the locking position, so that the locking tongue engages with the limiting tooth groove, completing the locking of the table board.

Detailed Implementation

[0040] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0041] like Figures 1 to 8 As shown, an adjustable vehicle tray table includes: a base plate 100, on which a slidable tray table 200 is mounted; one of the base plate 100 and the tray table 200 has a slider portion 300 and the other has a groove portion 400; the slider portion 300 is disposed within the groove portion 400 and the two are allowed to slide relative to each other; the slider portion 300 is provided with a mounting groove 310 and a locking groove 320; and a locking member 500, which is movably mounted in the locking groove 320; the travel positions of the locking member 500 include a locked position and an unlocked position; when the locking member 500 is in the locked position... The locking member 500 is locked to the other of the substrate 100 and the table 200 to restrict the table 200 from sliding relative to the substrate 100. When the locking member 500 is in the unlocked position, the locking member 500 is separated from the other of the substrate 100 and the table 200 to allow the table 200 to slide relative to the substrate 100. The unlocking member 600 is movably mounted in the mounting groove 310 and is linked to the locking member 500. The unlocking member 600 can drive the locking member 500 to move by its own movement. The position of the locking member 500 is determined by the position of the unlocking member 600.

[0042] The base plate 100 is the base part of the whole small table 200, which can be flat or folded up with the rotation of the folding connector 700. The table plate 200 can be regarded as the actual use of the desktop part, which is installed on the base plate 100 and can slide relative to the base plate 100. The slider part 300 and the sliding groove part 400 cooperate with each other, so that the table plate 200 can smoothly slide on the base plate 100. The locking piece 500 is a key component for locking or unlocking the position of the table plate 200, and the locking piece 500 is movably installed in the locking groove 320 and can be switched between the locking position and the unlocking position. The unlocking piece 600 is responsible for controlling the state conversion of the locking piece 500, and the unlocking piece 600 is installed in the mounting groove 310 of the slider part 300 and is connected with the locking piece 500. The unlocking piece 600 is provided with an unlocking key, and the unlocking piece 600 can be pulled to slide by pulling the unlocking key with the fingers, so as to adjust left and right. By moving the unlocking piece 600, the locking piece 500 can be directly driven to move to the locking position or the unlocking position, so as to realize the control of the locking / free state of the table plate 200.

[0043] In an embodiment, the bottom of the table plate 200 is provided with the slider part 300, which cooperates with the sliding groove part 400 on the base plate 100 to allow the table plate 200 to slide along the preset direction to adjust the position. When the locking piece 500 is in the locking position, the locking piece 500 will be locked with the base plate 100 to prevent the table plate 200 from sliding; and when the locking piece 500 is in the unlocking position, the locking piece 500 is separated from the base plate 100 to allow the table plate 200 to slide freely.

[0044] The core principle of the design is to control the state of the locking piece 500 through the unlocking piece 600. In the normal state, the locking piece 500 is in the locking position, which locks the table plate 200 and the base plate 100 together, thereby limiting the sliding of the table plate 200. When it is necessary to adjust the position of the table plate 200, the user only needs to pull the unlocking piece 600 to move the locking piece 500 to the unlocking position, at which time the table plate 200 can freely slide to adjust the position. After the adjustment is completed, the unlocking piece 600 is reset, and the locking piece 500 returns to the locking position to re-lock the table plate 200 and the base plate 100 together to prevent the table plate 200 from further sliding.

[0045] The table plate 200 can slide left and right relative to the base plate 100, and users can easily adjust the position of the table plate 200 according to their own needs or space limitations, improving the flexibility and comfort of use. Through the cooperation of the unlocking part 600 and the locking part 500, an effective limiting self-locking mechanism is formed. When the table plate 200 is adjusted to the desired position, it can be quickly locked to ensure that the table plate 200 does not accidentally slide during use, enhancing the stability and safety of use. After the table plate 200 is adjusted to the appropriate position, the table plate 200 can be immediately locked, avoiding the problem of displacement of the table plate 200 due to vibration or other external forces during vehicle travel, ensuring the reliability and stability during use.

[0046] On the basis of the above-mentioned embodiments, the sliding groove part 400 is provided with a limiting tooth groove 410, which is set as a rack structure extending along the sliding direction of the table plate 200, and the locking part 500 is provided with a locking tongue 510; when the locking part 500 is in the locking position, the locking tongue 510 engages with the limiting tooth groove 410 to limit the movement of the table plate 200.

[0047] The sliding groove part 400 not only serves as a track for the table plate 200 to slide relative to the base plate 100, but also has a limiting tooth groove 410 structure on its structure. The teeth on these limiting tooth grooves 410 extend along the sliding direction of the table plate 200, forming a rack structure. This design provides a physical locking point for the locking part 500, further enhancing the stability and reliability of the position locking of the table plate 200. The locking part 500 is equipped with a locking tongue 510, which is designed to match the limiting tooth groove 410. When the user finishes adjusting the position of the table plate 200, the locking part 500 will move to the locking position, at which time the locking tongue 510 will engage with the limiting tooth groove 410.

[0048] On the basis of the above-mentioned embodiments, the sliding groove part 400 is set as a groove structure extending along the sliding direction of the table plate 200, the sliding block part 300 is set as a protruding structure matching the cross-sectional shape of the sliding groove part 400, and the limiting tooth groove 410 is set on the side surface of the sliding groove part 400; when the locking part 500 is in the locking position, the locking tongue 510 protrudes from the side surface of the sliding block part 300.

[0049] The slide groove 400 is a recessed structure extending along the sliding direction of the tabletop 200. Its main function is to serve as a track for the slider 300, allowing the tabletop 200 to slide smoothly left and right. The slide groove 400 not only provides a sliding path but also has a limiting toothed groove 410 on its side. Matching the slide groove 400 is the slider 300, which is designed as a protruding structure with a cross-sectional shape perfectly adapted to the slide groove 400. This ensures that the slider 300 can move smoothly within the slide groove without wobbling or derailment. The locking member 500 is equipped with a locking tongue 510. When the locking member 500 is in the locked position, the locking tongue 510 protrudes from one side of the slider 300 and engages in the limiting toothed groove 410, thereby achieving mechanical locking.

[0050] The limiting tooth groove 410 is provided on the side of the slide groove 400, and the locking tongue 510 protrudes from the side of the slider 300. The side of the slide groove 400 and the side of the slider 300 are arranged face to face. The locking tongue 510 can move laterally (i.e., move relative to the width direction of the slide groove 400) to engage and lock with the limiting tooth groove 410 on the side. This lateral locking mechanism can provide additional locking force and stability.

[0051] like Figures 1 to 8 As shown, based on the above embodiment, the unlocking member 600 is provided with a sloping groove 610, the two sides of which are a first driving sloping surface 611 and a second driving sloping surface 612 respectively. The locking member 500 includes a force-receiving part 520, the two sides of which are a first force-receiving sloping surface 521 and a second force-receiving sloping surface 522 respectively. The first driving sloping surface 611 contacts the first force-receiving sloping surface 521, and the second driving sloping surface 612 contacts the second force-receiving sloping surface 522. When the unlocking member 600 moves, the first driving sloping surface 611 pushes the first force-receiving sloping surface 521, thereby driving the locking member 500 to move toward the unlocking position. When the unlocking member 600 moves in the opposite direction, the second driving sloping surface 612 pushes the second force-receiving sloping surface 522, thereby driving the locking member 500 to move toward the locking position.

[0052] The chute portion 610 has two different driving slopes, i.e., a first driving slope 611 and a second driving slope 612, which are respectively located on both sides of the chute portion 610 and used to contact the force receiving portion 520 on the locking piece 500. The locking piece 500 includes a force receiving portion 520, and the two sides of the force receiving portion 520 are respectively a first force receiving slope 521 and a second force receiving slope 522. The locking piece 500 is arranged between the first driving slope 611 and the second driving slope 612, so that the first driving slope 611 and the second driving slope 612 correspond to the first force receiving slope 521 and the second force receiving slope 522 respectively. When the unlocking piece 600 moves in a certain direction (i.e., the direction of making the first driving slope 611 close to the first force receiving slope 521), the first driving slope 611 will contact the first force receiving slope 521 and apply a pushing force, which pushes the locking piece 500 to move towards the unlocking position, so that the locking tongue 510 exits the limiting tooth groove 410, the locking state of the table board 200 is released, and the table board 200 is allowed to slide freely. When the unlocking piece 600 moves reversely (i.e., the direction of making the second driving slope 612 close to the second force receiving slope 522), the second driving slope 612 will contact the second force receiving slope 522 and apply a pushing force in the opposite direction, which pushes the locking piece 500 to the locking position, so that the locking tongue 510 reenters the limiting tooth groove 410, and the locking of the table board 200 is completed.

[0053] Since the table board 200 is adjusted by sliding left and right, the locking piece 500 needs to move in the front-back direction to realize the locking or unlocking function. However, it is not convenient for passengers to directly operate the locking piece 500 from the front-back direction, because it is not ergonomic and the arm movement is not natural. In order to solve this problem, the design adopts the slope contact mode of the chute portion 610 and the force receiving portion 520, so that the moving direction (left-right direction) of the unlocking piece 600 and the moving direction (front-back direction) of the locking piece 500 are perpendicular to each other. Specifically, the unlocking piece 600 controls the position of the locking piece 500 by moving left and right, and when the passenger pushes the unlocking piece 600 left or right, the first driving slope 611 of the unlocking piece 600 will apply a pushing force to the first force receiving slope 521 of the locking piece 500, so as to make the locking piece 500 move forward or backward to the unlocking position.

[0054] In this embodiment, the slope driving mechanism is ingeniously utilized, the passenger can easily operate the unlocking piece 600 by natural finger movement (left-right direction), without trying to directly drive the locking piece 500 from the front-back direction, which improves the comfort and convenience of operation. Through the precise matching between the slopes, the locking and unlocking of the table board 200 can be realized by simply pushing the unlocking piece 600 left and right, which simplifies the operation steps and improves the user experience.

[0055] It should be noted here that the direction in which the unlocking member 600 moves is perpendicular to the direction in which the locking member 500 moves, and this design can optimize the comfort of the unlocking operation. Since the table board 200 is adjusted by sliding left and right, the moving direction of the locking member 500 is forward and backward, and it is difficult for the passenger's arm to directly drive the locking member 500 to move in the forward and backward direction. Therefore, by driving the unlocking member 600 in a slanted way, the unlocking member 600 can control the locking member 500 to move forward and backward by moving left and right, so as to facilitate the passenger to operate the unlocking member 600.

[0056] On the basis of the above-mentioned embodiments, the stress receiving portion 520 is slidably arranged in the slanted groove portion 610, and the length of the stress receiving portion 520 is greater than the length of the slanted groove portion 610.

[0057] The stress receiving portion 520 is located in the slanted groove portion 610, which means that the stress receiving portion 520 is located between the first driving slanted surface 611 and the second driving slanted surface 612, so that the first driving slanted surface 611 and the second driving slanted surface 612 can correspond to the first stress receiving slanted surface 521 and the second stress receiving slanted surface 522 respectively. The length of the stress receiving portion 520 is designed to be longer than the length of the slanted groove portion 610, so that the first stress receiving slanted surface 521 and the second stress receiving slanted surface 522 can always be in contact with the first driving slanted surface 611 and the second driving slanted surface 612 respectively during the movement of the stress receiving portion 520.

[0058] On the basis of the above-mentioned embodiments, the locking groove 320 includes two guide groove bodies 321, the two guide groove bodies 321 extend in the same direction, the extension direction of the guide groove body 321 is the sliding direction of the locking member 500, and the locking member 500 further includes two guide portions 530, the two guide portions 530 are respectively located at both ends of the stress receiving portion 520, the two guide portions 530 are respectively in sliding connection with the two guide groove bodies 321, and the guide portion 530 can only slide in the extension direction of the guide groove body 321.

[0059] Due to the design of the guide groove body 321 and the guide portion 530, the movement of the locking member 500 is strictly limited in the sliding direction (i.e. the forward and backward direction), and cannot move in other directions. Since the locking member 500 has no freedom in the left and right directions, it can effectively fix the table board 200 at the selected position.

[0060] Further, the width of the guide groove body 321 is consistent with the width of the guide portion 530, which effectively limits the movement of the locking member 500 in the forward and backward direction, thereby eliminating any lateral (left and right) freedom. This precise mechanical constraint is crucial for achieving reliable locking between the table board 200 and the base plate 100 in the left and right directions.

[0061] As Figures 1 to 8As shown, on the basis of the above-mentioned embodiments, a locking spring 620 is further included, one end of which is connected with the unlocking member 600 and the other end is connected with the sliding block 300, and the locking spring 620 exerts a spring force on the locking member 500 through the unlocking member 600, tending to return the locking member 500 to the locking position.

[0062] The design of the locking spring 620 further enhances the automatic reset capability of the locking member 500 and the reliability of the locking mechanism. This design ensures that the locking member 500 can automatically return to the locking position without external operation, providing a more stable locking effect.

[0063] The locking spring 620 is designed to exert a continuous spring force on the unlocking member 600, which is transmitted to the locking member 500 through the unlocking member 600, tending to return the locking member 500 to the locking position. When there is no external force (i.e. the passenger does not operate the unlocking member 600), the locking spring 620 will automatically push the unlocking member 600, thereby driving the locking member 500 into the locking position, so that the locking tongue 510 engages with the limiting tooth groove 410, completing the locking of the table board 200. When the passenger needs to adjust the position of the table board 200, they overcome the spring force of the locking spring 620 by operating the unlocking member 600, moving the locking member 500 to the unlocking position. At this time, the locking tongue 510 exits from the limiting tooth groove 410, allowing the table board 200 to slide freely.

[0064] As shown in Figure 1 , Figure 4 on the basis of the above-mentioned embodiments, the table board 200 is movably sleeved on the base plate 100, one of the table board 200 and the base plate 100 is provided with a stroke limiting groove 330 and the other is provided with a stroke limiting block 110, the stroke limiting block 110 is slidably arranged in the stroke limiting groove 330 and limits the maximum sliding stroke of the table board 200.

[0065] By arranging the stroke limiting groove 330 and the stroke limiting block 110 between the table board 200 and the base plate 100, the maximum sliding stroke of the table board 200 relative to the base plate 100 is effectively limited, ensuring that the table board 200 will not slide out of the base plate 100 or exceed the predetermined use range.

[0066] As shown in Figure 1 , Figure 3 , Figure 9 , Figure 10 on the basis of the above-mentioned embodiments, further including a folding connecting member 700, a movable connecting member 800 and a lifting connecting member 900, the movable connecting member 800 is slidably connected with the lifting connecting member 900, the sliding direction of the movable connecting member 800 is perpendicular to the sliding direction of the table board 200, the folding connecting member 700 is hingedly connected with the movable connecting member 800, and the base plate 100 is fixedly connected with the folding connecting member 700.

[0067] On the basis of the above-mentioned embodiments, the lifting connecting piece 900 is fixedly provided with a coil spring 910, the coil spring 910 is connected with the movable connecting piece 800, the coil spring 910 always applies a pulling force to the movable connecting piece 800 to make it tend to the initial position, the folding connecting piece 700 is provided with a clamping tooth 710, the lifting connecting piece 900 is provided with a rack part 920, when the folding connecting piece 700 rotates to the position in which the table board 200 is flat, the clamping tooth 710 meshes with the rack part 920, thereby limiting the sliding of the movable connecting piece 800.

[0068] The movable connecting piece 800 is slidingly connected with the lifting connecting piece 900, and the sliding direction of the movable connecting piece 800 is perpendicular to the left-right sliding direction (i.e. the front-rear direction) of the table board 200. Since the movable connecting piece 800 is directly or indirectly connected with the table board 200, it can move together with the table board 200 in the front-rear direction, thereby realizing the front-rear adjustment function of the small table board 200. The lifting connecting piece 900 is fixedly provided with a coil spring 910, the coil spring 910 is connected with the movable connecting piece 800, and always applies a pulling force to the movable connecting piece 800 to make it tend to the initial position. The folding connecting piece 700 is hingedly connected with the movable connecting piece 800, and the base plate 100 is fixedly connected with the folding connecting piece 700, so that the whole table board 200 can be flat or turned up through the folding connecting piece 700, when the table board 200 is adjusted to the horizontal position (flat state), the clamping tooth 710 on the folding connecting piece 700 meshes with the rack part 920 on the lifting connecting piece 900, thereby limiting the further sliding of the movable connecting piece 800. Specifically, the meshing of the clamping tooth 710 and the rack part 920 forms a mechanical locking mechanism, once the table board 200 is flat, the locking mechanism is started, and any movement of the movable connecting piece 800 in the front-rear direction is prevented.

[0069] Through the front-rear adjustment function of the movable connecting piece 800 and the left-right sliding adjustment of the table board 200 itself, the user can very flexibly adjust the position of the table board 200 to meet different use requirements.
