Description

Technical Field

[0001] This application relates to the technical field of seat accessories, specifically to a liftable storage box and armrest. Background Technology

[0002] With the continuous development of the automotive industry, people have increasingly higher requirements for the functionality, aesthetics, and comfort of automotive interior components. Among them, the passenger-side dashboard armrest, as an important supplementary space to the dashboard, is a crucial interior component. The passenger-side dashboard armrest typically includes elbow rests, storage boxes, cup holders, and handbrakes. Currently, storage boxes and cup holders on passenger-side dashboard armrests are mostly separate units, while storage boxes are mostly fixed. Based on their functionality, they can be divided into partitioned or unpartitioned types, and cup holders can be fixed, lift-up, or rotating. However, due to their limited functionality, space utilization is low, and the overall aesthetic integrity of the passenger-side dashboard armrest is affected. Summary of the Invention

[0003] To address at least one aspect of the aforementioned problems, the present invention provides a liftable storage box, comprising a storage box assembly, the storage box assembly including at least two fixed plates, at least two movable plates, a storage box cover, at least two sets of first sliding components, at least one first elastic element, and at least one set of first locking components; the two fixed plates are respectively fixedly or detachably connected to two inner side walls of the mounting cavity for which a handrail is to be installed; the two movable plates are respectively disposed opposite to the two fixed plates; the two sets of first sliding components are respectively connected between the two fixed plates and the movable plates, such that the movable plates are slidably connected to the fixed plates in the vertical direction via the first sliding components; the storage box cover matches the mounting cavity, and the bottom surface or side surface of the storage box cover is flush with the two movable plates. The top is fixedly connected. When the storage box cover is in the high position, the dimensions of the fixed plate, the movable plate, and the storage box cover in the vertical direction match the dimensions of the mounting cavity in the vertical direction. The first elastic element and the first locking assembly are both connected between the fixed plate and the movable plate. When the storage box cover is in the low position, the first elastic element is in the natural state and the first locking assembly is in the unlocked state. When the storage box cover is in the high position, the first locking assembly is in the locked state and the first elastic element is in the stretched or compressed state. Alternatively, when the storage box cover is in the high position, the first elastic element is in the natural state and the first locking assembly is in the unlocked state. When the storage box cover is in the low position, the first locking assembly is in the locked state and the first elastic element is in the stretched or compressed state.

[0004] Through the above technical solution, the storage box is designed to be liftable. When the storage box cover is in the high position, the dimensions of the fixed plate, the moving plate, and the storage box cover along the vertical direction are designed to match the dimensions of the mounting cavity along the vertical direction. This ensures that after the storage box is installed on the mounting cavity of the handrail, when there is no need for storage, the top surface of the storage box cover is flush with the top surface of the handrail, thus achieving the integrity of the handrail shape. The first elastic element and the first locking component limit the storage box cover in the low and high positions, respectively, so that the lifting and lowering of the storage box cover can be driven by mechanical structure alone, which is low-cost and easy to operate.

[0005] Since items may be placed on the storage box lid, such as an integrated cup holder assembly, the lid also needs to bear the weight of the cup holder assembly and the cup, as well as the pressure exerted when the lid is pressed down if the cup holder is a lift-up type. Preferably, when the storage box lid is in a low position, the first elastic element is in a natural state, and the first locking component is in an unlocked state; when the storage box lid is in a high position, the first locking component is in a locked state, and the first elastic element is in a stretched state, which further contributes to the stability of the storage box lid.

[0006] Preferably, the fixed plate has a through first mounting hole, and the first locking assembly is a labyrinth locking mechanism. The first locking assembly includes a first rotating member and a first locking block. The first rotating member includes a first rotating part, a first opening part, a first channel part, and a first locking part from bottom to top. The first rotating part is rotatably connected to the bottom wall of the first mounting hole, and a first limiting torsion spring is connected to the first rotating part. The bottom end of the first opening part is an open structure, and the first opening part and the first locking part are connected through the first channel part. A first stop block is fixedly connected inside the first locking part, and the first stop block and the inner wall of the first locking part form a first trajectory groove. A first fixing groove is provided on the top of the first stop block, and a first unlocking limit groove and a first locking limit groove are provided on the inner wall of the top of the first locking part. The first locking block is adapted to the first channel part, the first trajectory groove, the first fixing groove, the first unlocking limit groove, and the first locking limit groove. The first locking block is fixedly connected to the outer side of the moving plate.

[0007] Through the above technical solution, when the storage box lid is in a high position and storage is needed, the first locking component is unlocked by pulling the lid upwards. Under the action of the first elastic element, the lid automatically moves downwards. When the storage box is in a low position and there is no storage need, the lid is pulled upwards against the tension of the first elastic element until the first locking component is locked. By designing the unlocking mechanism of the first locking component to be an upward pull, the first locking component remains locked even when there is no storage need and the lid is subjected to downward pressure, preventing the lid from descending and ensuring its stability.

[0008] Preferably, at least three first stop bars are fixedly connected to the outer wall of the top of the first locking part. The top side of the middle first stop bar overlaps with one side of the fixing plate above the first mounting hole, and the top sides of the other two first stop bars overlap with the other side of the fixing plate above the first mounting hole, which helps to ensure the smooth operation of the first locking assembly.

[0009] Preferably, the storage box assembly further includes at least one first damping component, which includes a first damping gear and a first rack; the first damping gear is rotatably connected to the moving plate, and the first rack is fixedly connected to the inner side of the fixed plate along the vertical direction, with the first damping gear meshing with the first rack. Through the above technical solution, the first damping component is designed to limit the speed of the storage box cover during its automatic descent, which helps to stabilize the operation of the storage box cover.

[0010] Preferably, the first sliding assembly includes a guide rail groove and a slide bar; the guide rail groove is fixedly connected to the inner side of the fixed plate in the vertical direction, the slide bar is fixedly connected to the moving plate in the vertical direction, and the slide bar passes through the guide rail groove and is slidably connected to the guide rail groove in the vertical direction.

[0011] Preferably, the slide bar is provided with at least one elastic pressure plate, the elastic pressure plate includes a connecting part and a protrusion, the connecting part is detachably connected to the slide bar, and the protrusion abuts against the inner wall of the guide rail groove. By providing the elastic pressure plate, it helps to increase the friction between the slide bar and the guide rail groove, thereby improving the stability of the operation between the slide bar and the guide rail groove.

[0012] Preferably, the storage box cover has at least one through hole, and at least one cup holder assembly is provided on the storage box cover, with the cup holder assembly corresponding to the through hole. By integrating the cup holder into the storage box cover using the above technical solution, the functions of the storage box and the cup holder are integrated, which helps to improve space utilization.

[0013] Preferably, the cup holder assembly includes a cup holder, a cup holder cover, at least one set of second sliding components, a second elastic element, and a second locking component; the cup holder is vertically cylindrical, with its opening corresponding to a through hole, and the open end of the cup holder is fixedly or detachably connected to the storage box cover; the cup holder cover matches both the opening and the through hole, and the second sliding component is connected between the cup holder cover and the inner wall of the cup holder, allowing the cup holder cover to slide vertically with the cup holder via the second sliding component; when the cup holder cover is in a high position, the top surface of the cup holder cover is aligned with the top surface of the storage box cover. The cup holder is flush with the cup tray. The second elastic element and the second locking component are both connected between the cup holder cover and the cup holder. When the cup holder cover is in the low position, the second elastic element is in the natural state and the second locking component is in the unlocked state. When the cup holder cover is in the high position, the second locking component is in the locked state and the second elastic element is in the stretched or compressed state. Alternatively, when the cup holder cover is in the high position, the second elastic element is in the natural state and the second locking component is in the unlocked state. When the cup holder cover is in the low position, the second locking component is in the locked state and the second elastic element is in the stretched or compressed state.

[0014] The above technical solution discloses a specific structure of a lifting cup holder assembly. The cup holder cover in the high position is designed to be flush with the storage box cover to achieve the integrity of the armrest shape. The cup holder cover in the low position and the cup holder cover in the high position are limited by the second elastic element and the second locking component respectively, so that the lifting and lowering of the cup holder cover can be driven by mechanical structure alone. The cost is low and the operation is convenient.

[0015] Preferably, when the cup holder cover is in the low position, the second locking component is in the locked state and the second elastic element is in the compressed state; when the cup holder cover is in the high position, the second elastic element is in the unloaded state and the second locking component is in the unlocked state. Since the cup holder cover bears the weight of the cup when it is in the low position, designing the second locking component to be in the locked state when the cup holder cover is in the low position helps ensure the stability of the cup holder cover, thereby contributing to the stability of the cup.

[0016] Preferably, the cup holder has a second mounting hole, and the second locking assembly is a labyrinth locking mechanism. The second locking assembly includes a second rotating member and a second locking block. The second rotating member includes a second rotating part, a second open part, a second channel part, and a second locking part from top to bottom. The second rotating part is rotatably connected to the top wall of the second mounting hole, and a second limiting torsion spring is connected to the second rotating part. The bottom end of the second open part is an open structure, and the second open part and the second locking part are connected through the second channel part. A second stop is fixedly connected inside the second locking part, and the second stop and the inner wall of the second locking part form a second trajectory groove. A second fixing groove is provided at the bottom of the second stop, and a second unlocking limit groove and a second locking limit groove are provided on the inner wall of the bottom of the second locking part. The second locking block is adapted to the second channel part, the second trajectory groove, the second fixing groove, the second unlocking limit groove, and the second locking limit groove. The second locking block is fixedly connected to the side of the cup holder cover. The above technical solution discloses the specific structure of the second locking component. When the cup holder cover is in a high position and there is a need to place a cup, the second elastic member is used to press down the cup holder cover until the second locking component locks it. When the cup holder cover is in a low position and there is no need to place a cup, the cup holder cover is pressed down to unlock it. Under the action of the second elastic member, the cup holder cover automatically rises to the high position.

[0017] This application also provides a handrail, including a liftable storage box and a handrail body as described above. An installation cavity is provided on the top surface of the handrail body. Two fixing plates are fixedly connected to or detachably connected to the two sides of the inner wall of the installation cavity. When the storage box cover is in a high position, the top surface of the storage box cover is flush with the top surface of the handrail body.

[0018] The present invention provides a liftable storage box and handrail, which have the following beneficial effects:

[0019] (1) By designing the storage box as a liftable type, and when the storage box cover is in a high position, the dimensions of the fixed plate, the movable plate and the storage box cover along the vertical direction are designed to match the dimensions of the mounting cavity along the vertical direction, so that when the storage box of this application is installed on the mounting cavity of the handrail, the top surface of the storage box cover is flush with the top surface of the handrail when there is no storage need, thus achieving the integrity of the handrail shape.

[0020] (2) By integrating the cup holder assembly into the storage box assembly, and designing both the cup holder assembly and the storage box assembly as lifting types, the storage function is realized when the storage box cover is in a low position and the cup holder cover is in a high position, and the function of placing water cups is realized when the storage box cover is in a low or high position and the cup holder cover is in a low position. This realizes the integration of the functions of the storage box and the cup holder, which is conducive to improving space utilization. When both the cup holder cover and the storage box cover are in a high position, the top surface of the storage box cover and the cup holder cover is flush with the top surface of the component to be installed, thus achieving the integrity of the overall shape of the armrest.

[0021] (3) When the storage box cover is in a low position, the first elastic element is designed to be in a natural state and the first locking component is designed to be in an unlocked state; when the storage box cover is in a high position, the first locking component is designed to be in a locked state, the first elastic element is designed to be in a stretched state, and the first locking component is designed to be pulled upward to unlock. This ensures that the first locking component remains locked even when the cup holder cover, the cup holder assembly, and the cup are pressed down, thus preventing the storage box cover from falling down and ensuring the stability of the storage box cover.

The movable plates 12 are vertically arranged, and the two movable plates 12 are respectively parallel to and opposite to the two fixed plates 11. The two sets of first sliding components 14 are respectively connected between the two fixed plates 11 and the two movable plates 12, so that the movable plates 12 are slidably connected to the fixed plates 11 in the vertical direction through the first sliding components 14.

[0042] In this embodiment, four sets of sliding components are provided. Two sets of sliding components are respectively disposed between a set of movable plates 12 and fixed plates 11. Specifically, the first sliding component 14 includes a guide groove 141 and a slider 142. The guide groove 141 is arranged vertically. The guide grooves 141 of the two sets of first sliding components 14 are respectively disposed on both sides of the inner side of the fixed plate 11. The orientation of the two guide grooves 141 is preferably facing each other. Several protrusions 1411 are fixedly connected to the side of the guide groove 141 facing the fixed plate 11 along the vertical direction. Several grooves 112 are provided on both sides of the inner side of the fixed plate 11 along the vertical direction.

When the storage box cover 13 is in the low position, the first locking component 16 is in the locked state and the first elastic element is in the stretched or compressed state. Preferably, when the storage box cover 13 is in the low position, the first elastic element is in the natural state and the first locking component 16 is in the unlocked state; when the storage box cover 13 is in the high position, the first locking component 16 is in the locked state and the first elastic element is in the stretched state, which is more conducive to the stability of the storage box cover 13.

[0045] Specifically, one first elastic element and one first locking assembly 16 are each provided, disposed between one set of fixed plates 11 and movable plates 12. Preferably, two first elastic elements and two first locking assemblies 16 are each provided, disposed between two sets of fixed plates 11 and movable plates 12 respectively. The first elastic element is a straight spring 24, a torsion spring, or an elastic band. In this embodiment, the first elastic element is a connecting torsion spring 15. A horizontally arranged connecting post is fixedly connected to the inner wall of the fixed plate 11. The connecting torsion spring 15 is sleeved on the connecting post, with one end fixedly connected to the inner side of the fixed plate 11 and the other end fixedly connected to the outer side of the movable plate 12.

[0046] The fixing plate 11 has a through first mounting hole 113. The first locking assembly 16 is a labyrinth locking mechanism.

The first rotating part 1611 is rotatably connected to the bottom wall of the first mounting hole 113. A first rotation limiting torsion spring is sleeved on the first rotating part 1611. One end of the first rotation limiting torsion spring is connected to the first rotating part 1611, and the other end is connected to the fixing plate 11. The bottom end of the first opening part 1612 is an open structure, and the first opening part 1612 and the first locking part 1614 are connected through the first channel part 1613. A first stop block 1615 is fixedly connected inside the first locking part 1614. The first stop block 1615 and the inner wall of the first locking part 1614 form a first locking block 1614. A trajectory groove; a first fixing groove 1616 is provided on the top of the first stop block 1615, making the first stop block heart-shaped; a first unlocking limiting groove 1617 and a first locking limiting groove 1618 are provided on the inner wall of the top of the first locking part 1614; the first locking block 162 is adapted to the first channel part 1613, the first trajectory groove, the first fixing groove 1616, the first unlocking limiting groove 1617 and the first locking limiting groove 1618, and the first locking block 162 is fixedly connected to the outer side of the moving plate 12; preferably, at least three first stop bars 1619 are fixedly connected to the outer wall of the top of the first locking part 1614, the top side of the middle first stop bar 1619 overlaps with one side of the fixing plate 11 above the first mounting hole 113, and the top sides of the other two first stop bars 1619 overlap with the other side of the fixing plate 11 above the first mounting hole 113, which helps to stabilize the first locking assembly 16.

[0047] The changes of the first locking component 16 during the operation of the storage box assembly 1 are as follows: When the storage box cover 13 is in the high position, the first locking block 162 is located in the first fixing groove 1616, and the first locking component 16 is in the locked state, such as... Figure 8 As shown; when storage is needed, the user pulls the storage box cover 13 upwards via the handle groove, and the first locking block 162 moves from the first fixing groove 1616 to the first unlocking limit groove 1617. Figures 8 to 9 As shown, the storage box cover 13 is then released. Under the tension of the connecting torsion spring 15, the first locking block 162 moves vertically downwards and along the first track groove on one side of the first stop block 1615.

[0051] The second elastic element and the second locking component 25 are both connected between the cup holder cover 22 and the cup holder 21. When the cup holder cover 22 is in the low position, the second elastic element is in the natural state and the second locking component 25 is in the unlocked state. When the cup holder cover 22 is in the high position, the second locking component 25 is in the locked state and the second elastic element is in the stretched or compressed state. Alternatively, when the cup holder cover 22 is in the high position, the second elastic element is in the natural state and the second locking component 25 is in the unlocked state, and when the cup holder cover 22 is in the low position, the second locking component 25 is in the locked state and the second elastic element is in the stretched or compressed state.

[0053] In some embodiments, the cup holder assembly 2 is designed as two sets, and a vertical fixing strip 27 is provided between the two cup holders 21 in the two sets of cup holder assemblies 2. Preferably, there are two fixing strips 27, which are arranged opposite to each other. The end faces of the fixing strips 27 along the vertical direction are respectively fixedly connected to the outer walls of the two cup holders 21. Each cup holder 21 has a through hole that extends vertically. A connecting plate 2221 is fixedly connected to the side wall of the cover plate seat 222 in the cup holder cover plate 22. The connecting plate 2221 passes through the elongated hole and is opposite to the fixing strip 27, and moves vertically in the elongated hole. The second locking component 25 of the two cup holder assemblies 2 is connected between the two connecting plates 2221 and the same fixing strip 27, or between the two connecting plates 2221 and the two fixing strips 27.

[0054] Specifically, the fixing strip 27 has a second mounting hole 271, and the second locking assembly 25 is a labyrinth locking mechanism. The second locking assembly 25 includes a second rotating member 251 and a second locking block 252. The second rotating member 251 includes a second rotating part 2511, a second opening part 2512, a second channel part 2513, and a second locking part 2514 from top to bottom. The second rotating part 2511 is rotatably connected to the top wall of the second mounting hole 271, and a second locking block 252 is fitted on the second rotating part 2511. The second torsion spring has one end connected to the second rotating member 251 and the other end connected to the fixing strip 27. The bottom end of the second open portion 2512 is open, and the second open portion 2512 and the second locking portion 2514 are connected through the second channel portion 2513. A second stop block 2515 is fixedly connected inside the second locking portion 2514, and the second stop block 2515 and the inner wall of the second locking portion 2514 form a second track groove. A second fixed groove is opened at the bottom of the second stop block 2515. The fixed groove 2516 makes the second stop 2515 in an inverted heart shape. A second unlocking limiting groove 2517 and a second locking limiting groove 2518 are provided on the inner wall of the bottom of the second locking part 2514. The second locking block 252 is adapted to the second channel part 2513, the second track groove, the second fixing groove 2516, the second unlocking limiting groove 2517, and the second locking limiting groove 2518. The second locking block 252 is fixedly connected to the side of the cup holder cover plate 22. In this embodiment, the second locking block... 252 is fixedly connected to the connecting plate 2221 on the outer side of the cover plate seat 222; preferably, at least three second stop bars 2519 are fixedly connected to the outer wall of the bottom of the second locking part 2514, the bottom side of the middle second stop bar 2519 overlaps with one side of the fixing bar 27 below the second mounting hole 271, and the bottom sides of the other two second stop bars 2519 overlap with the other side of the fixing bar 27 below the second mounting hole 271, which helps to stabilize the second locking assembly 25.

[0055] The changes of the second locking component 25 during the operation of the cup holder assembly 2 are as follows: When the cup holder cover 22 is in the high position, the spring 24 is in the natural state; when there is a need to place a cup, the user overcomes the elastic force of the spring 24 and presses down on the cup holder cover 22, and the second locking block 252 enters the second opening part 2512 as follows. Figure 16 As shown, the second track groove enters the second stop block 2515 from the second channel section 2513. Figure 17 As shown, when the second locking block 252 moves to the second stop 2515 and is blocked, the second rotating component 251 will rotate under the pressure of the operator, and the second locking block 252 will move past the second stop 2515 to the second locking limit groove 2518. Figure 18 As shown, the operator then releases the cup holder cover 22, and under the action of the spring 24, the second locking block 252 moves vertically upward to the second fixing groove 2516 to reach the locking state. Figure 19 As shown; when the cup holder cover 22 is in the low position and there is no need to place a cup, the user presses down the cup holder cover 22, and the second locking block 252 moves from the second fixing groove 2516 to the second unlocking limit groove 2517 as shown. Figures 19 to 20 As shown, then the cup holder cover 22 is released. Under the action of the spring 24, the second locking block 252 moves vertically upward and along the second track groove on the other side of the second stop block 2515 as shown. Figure 21 As shown, it extends from the second passage section 2513 until it exits from the second opening section 2512. Figure 16 As shown.

Multiple connecting holes are evenly opened around the side wall of the cup holder 21, and multiple support claws 261 correspond to multiple connecting holes. The support claw 261 includes a support part 2611 and a rotating part 2612. The rotating part 2612 is rotatably connected to the side wall of the cup holder 21 located below the connecting hole. The limiting torsion spring 262 is sleeved on the rotating part 2612 and one end of it is fixedly connected to the side wall of the cup holder 21. The side of the support part 2611 facing the inside of the cup holder 21 is shaped like a >. When the cup holder cover 22 is in a high position, the bottom end of the cup holder cover 22 overlaps with the top surface of the support part 2611.
