Description

Technical Field

[0001] The present invention relates to the technical field of automotive parts, and particularly to a vertically movable cup holder for an automobile. Background Art

[0002] Nowadays, the usage of automobiles is increasing. Currently, cup holders are usually installed in the interior of automobiles, and the cup holders can be used to accommodate beverage containers of different heights. After retrieval, a Chinese patent with the patent number ZL201510030131.9 discloses a cup holder capable of adjusting the height of a tray. The cup holder has a frame body, a tray, and a height adjustment unit. The height adjustment unit includes: a locking member rotatably held on the tray; a guide groove formed on the side wall of the frame body to enable the locking member to move in the vertical direction; a lower locking recess formed on the groove side surface of the side wall facing the guide groove, and the tray is held in the lower position by locking the locking member; an upper locking recess formed on the groove side surface above the lower locking recess, and the tray is held in the upper position by locking the locking member; a locking pre-tightening member that pre-tightens the locking member in the locking direction of locking with the lower locking recess or the upper locking recess; an operating member that releases the locking between the locking member and the lower locking recess when the tray is in the lower position; and a movement pre-tightening member that pre-tightens the tray upward. Although this application can solve the problem of adjusting the height of the tray, there are still the following disadvantages in the use process: the height adjustment unit is basically distributed outside, occupying a relatively large overall space, the structure of the height adjustment unit is complex, and the adjustment is more troublesome, time-consuming and laborious. Therefore, there is room for improvement. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a vertically movable cup holder for an automobile, and the specific solution is as follows:

[0004] A vertically movable cup holder for a vehicle, comprising a tray, a tray base, a cup barrel, a cup holder bottom cover, an unlocking button assembly, a power lifting assembly and a bottom shell locking structure. The tray is fixedly connected to the tray base, and a cavity is formed between the tray and the tray base. The tray and the tray base are integrally located in the cup barrel. A power lifting assembly is provided between the tray base and the cup barrel. The cup barrel covers the cup holder bottom cover. The unlocking button assembly is provided on the cup barrel.

The cup holder bottom cover is locked with the tray base through the bottom shell locking structure. The tray base is locked with / separated from the bottom shell locking structure through the unlocking button assembly. The power lifting assembly includes a fixed outer shell, a rotating inner shell, a scroll spring, a spring rotating shaft, a driving ring gear, a transmission gear set and a guiding rack. The fixed outer shell is fixedly arranged in the cavity. The fixed outer shell, the rotating inner shell and the spring rotating shaft are arranged coaxially from outside to inside. The spring rotating shaft is linked with the rotating inner shell. The rotating inner shell can rotate relative to the fixed outer shell;

[0005] The scroll spring is coaxially arranged on the rotating inner shell. The fixed end of the scroll spring is limited and installed on the spring rotating shaft. The torque end of the scroll spring is limited and installed on the fixed outer shell;

[0006] An installation space is formed between the fixed outer shell and the rotating inner shell. The driving ring gear linked with the rotating inner shell is arranged in the installation space. The transmission gear set includes two synchronously moving outer gears and an inner gear. The inner gear is meshed with the driving ring gear. The outer gear is meshed with the guiding rack. All the guiding racks are vertically arranged on the cup barrel;

[0007] When the elastic potential energy stored in the scroll spring is the largest, the tray is at the bottom of the cup barrel to form a storage space for placing cups.

[0008] Further, the power lifting assembly further includes a buffer damper. The buffer damper is coaxially arranged on the fixed outer shell and is located in the installation space, and the buffer damper is cooperatively linked with the rotating inner shell.

[0009] Further, a plurality of limiting grooves are wound on the fixed outer shell. The transmission gear set further includes a connecting rod. The connecting rod is clamped with the limiting grooves. The outer gear and the inner gear are respectively arranged at both ends of the connecting rod.

[0010] Further, a clamping gap is formed in the spring rotating shaft in the radial direction, and the size of the clamping gap is adapted to the fixed end of the scroll spring.

[0011] Further, the tray includes an upper cover plate, a middle anti-slip plate, and a lower fastening plate that are sequentially attached. The middle anti-slip plate forms anti-slip protruding strips on the upper surface of the upper cover plate, and a plurality of the anti-slip protruding strips are evenly wound around the center of the tray;

[0012] A hook block is provided on one side of the lower fastening plate away from the middle anti-slip plate, and a locking block is formed on the outer wall of the fixed housing corresponding to the hook block. The hook block and the locking block are detachably hooked.

[0013] Further, the unlocking button assembly is located outside the cup barrel. The unlocking button assembly includes a button block, a button holder, and an unlocking rod. The button block and the unlocking rod are respectively connected to both ends of the button holder. The middle of the button holder can flip relative to the outer wall of the cup barrel. The button block can penetrate through the cup barrel in the radial direction of the cup barrel and extend inward or outward;

[0014] The bottom shell lock structure includes a locking rod, a stop hook, a rotating torsion spring, a reinforcing rib, a locking disk, and a connecting ring. The rotating torsion spring is fixed at the middle position of the bottom cover of the cup holder. The locking disk is rotatably connected to the bottom cover of the cup holder and the locking disk abuts against the free end of the rotating torsion spring. The connecting ring and the locking disk are coaxially arranged with the bottom cover of the cup holder. One end of the reinforcing rib is connected to the locking disk and the other end is connected to the connecting ring.

[0016] Further, a clamping structure is provided on the cup barrel. The clamping structure includes a claw, a claw holder, and a return torsion spring. The claw is rotatably connected to the claw holder through a first rotating shaft. The claw holder is rotatably connected to the outer wall of the cup barrel through a second rotating shaft. The return torsion spring is rotatably sleeved on the second rotating shaft. The return torsion spring has two free ends. One of the free ends is attached to the outer wall of the cup barrel, and the other free end abuts against the claw. A first extending groove and a second extending groove are formed through the cup barrel. The claw is located in the first extending groove and extends into the cup barrel. One end of the claw holder away from the claw is located in the second extending groove and extends into the cup barrel.

[0017] Furthermore, two cup holders may be arranged side by side.

[0018] Furthermore, the upper ends and lower ends of the two cup holders are integrally connected.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) When a cup needs to be placed, the cup is placed in the storage space between the cup bucket and the tray, so that the tray lifts the cup and the cup bucket serves to limit the cup from shaking. When the tray is not in use, the user applies force to the unlock button assembly to separate the unlock button assembly from the bottom shell lock structure, so that the cup holder bottom cover loses its restriction on the tray base. After the tray base loses its restriction, it can be driven by the power lifting assembly to move up and down away from the cup holder bottom cover. At this time, the tray is in a free state, and the elastic potential energy stored in the spiral spring is released. The elastic force generated drives the spring rotating shaft and the rotating inner shell to rotate synchronously. The active ring gear will rotate relative to the fixed outer shell with the rotating inner shell. As the active ring gear rotates, the inner gear rotates accordingly, and the outer gear also rotates with the inner gear. At the same time, the outer gear moves up along the path of the guide rack under the guidance of the guide rack until the tray stops moving and stops. The next time you need to place a cup again, you only need to press the tray until the unlock button assembly on the tray base and the bottom shell lock structure on the cup holder bottom cover are re-linked, so that the tray and the tray base are fixed to the bottom of the entire cup holder, making it easy to place the cup in the storage space.

[0021] In summary, the power lifting mechanism in the entire device is basically installed in the cavity, making full use of the space of the cavity, making the movement smoother, and reducing the occupation of external space. The coordination between the spiral spring, spring rotating shaft, active ring gear, transmission gear set, and guide rack improves the balance of the up and down movement of the pallet and the pallet base, and realizes the stable hovering of the pallet.

[0022] In addition, by setting a fixed outer shell, a rotating inner shell, and an active ring gear, when the rotating inner shell rotates, the active ring gear can drive all the transmission gear sets and simultaneously guide and buffer the lifting and lowering movement of the tray. The movement axis of the scroll spring, the rotating inner shell, and the active ring gear when working is coaxial with the entire cup holder, and the movement path of the transmission gear set is also parallel to the axial direction of the cup holder. The scroll spring serves as the power source when the tray moves upward along the axial direction of the cup holder, which can avoid power loss caused by changes in direction, angle, etc. during the transmission process as much as possible.

[0023] (2) By setting up a buffer damper, when the tray and the tray base move upward after unlocking, the damping effect generated by the buffer damper balances the power applied by the volute spring, enabling the tray to achieve a smooth movement similar to uniform speed, that is, further improving the hovering stability of the tray.

[0024] (3) By setting up a connecting rod to cooperate with the limiting groove, the connecting rod can be detachably and fixedly installed relative to the fixed outer casing, so that the outer gear and the inner gear, which are used for power transmission during the movement of the tray, can both achieve position adjustment, disassembly and replacement;

[0025] (4) By setting up a clamping gap, it is convenient for the volute spring to be stably limited on the spring rotating shaft, so as to be coaxially arranged with the fixed outer casing and the rotating inner casing. When the volute spring is working, the elastic potential energy of the volute spring can be fully, accurately and evenly exerted, avoiding eccentric wear caused by relative rotation between the rotating inner casing and the fixed outer casing, and affecting the smoothness of the tray movement.

[0026] (5) The tray is divided into an upper cover plate, a middle anti-slip plate and a lower fastening plate. The upper cover plate and the middle anti-slip plate cooperate to play a role in stabilizing and strengthening the cup to be placed on the tray. The lower fastening plate realizes the detachable setting of the tray on the fixed outer casing through the cooperation of the hook block and the locking block, which is convenient for installation and replacement.

Detailed implementation manners

[0036] The present invention will be further described in detail below in conjunction with embodiments and the accompanying drawings. However, the implementation manners of the present invention are not limited thereto.

[0037] Combined with Figures 1 to 6 , a vertically movable cup holder for an automobile includes a tray 2, a tray base 5, a cup barrel 1, a cup holder bottom cover 3, an unlocking button assembly 4, a power lifting assembly 6, and a bottom shell lock structure 7. Through the arrangement of the above-mentioned multiple structures, after the cup holder of the present invention is assembled at a preset position inside the vehicle, it is convenient for the user to stably place a liquid container such as a water cup in the cup holder during driving, or to restore the cup holder to a non-use state, and the operations required by the user are simple.

[0038] The cup barrel 1 and the cup holder bottom cover 3 cooperate as a bearing structure, and the tray 2, the tray base 5, the unlocking button assembly 4, the power lifting assembly 6, and the bottom shell lock structure 7 are basically arranged inside the cup barrel 1. The tray 2 is fixedly connected to the tray base 5, and the tray 2 and the tray base 5 form a cavity. The two are integrally cylindrical. The tray 2 and the tray base 5 are integrally located in the cup barrel 1. A power lifting assembly 6 is provided between the tray base 5 and the cup barrel 1. The cup barrel 1 covers the cup holder bottom cover 3. An unlocking button assembly 4 is provided on the cup barrel 1. A bottom shell lock structure 7 is provided in the cup holder bottom cover 3. The bottom shell lock structure 7 is linked with the unlocking button assembly 4. The tray base 5 makes a lifting movement relatively close to / away from the cup holder bottom cover 3 through the power lifting assembly 6. The cup holder bottom cover 3 is locked with the tray base 5 through the bottom shell lock structure 7. The tray base 5 is locked with / separated from the bottom shell lock structure 7 through the unlocking button assembly 4.

[0039] When the tray 2 is at the uppermost position, the side of the tray 2 away from the cup holder bottom cover 3 is flush with the end face of the cup barrel 1 away from the cup holder bottom cover 3, which is the initial state when the tray 2 is not in use. When the user needs to install a cup, press the tray 2 until the tray base 5 is fixed to the cup holder bottom cover 3. At this time, the tray 2 is at the bottom of the cup barrel 1 to form a storage space for placing the cup, which is the use state. After taking out the cup, press the unlocking button assembly 4 to make the tray 2 move in the reverse direction until it is flush with the surface of the cup barrel 1.

[0040] Combined with Figure 7 and Figure 8 In the present invention, the unlocking button assembly 4 and the bottom shell locking structure 7 are used to cooperate to realize the initial state and the use state of the tray 2 in the cup barrel 1. The unlocking button assembly 4 is located outside the cup barrel 1. The unlocking button assembly 4 includes a button block 41, a button holder 43 and an unlocking rod 42. The button block 41 and the unlocking rod 42 are integrally connected to both ends of the button holder 43 respectively. As can be seen from the figure, the middle part of the button holder 43 is hinged to the convex block on the outer wall of the cup barrel 1 by setting a rotating shaft. Therefore, the button holder 43 can be flipped relative to the outer wall of the cup barrel 1. In addition, a through groove adapted to the size of the button block 41 is opened in the upper part of the cup barrel 1. At the through groove, the button block 41 can be radially penetrated through the cup barrel 1 and extend inwards or outwards. When the button block 41 is pressed by an external force, the button block 41 extends outwards from the inside of the cup barrel 1, and the button holder 43 flips along with the button block 41, thereby driving the unlocking rod 42 to move towards the cup barrel 1.

[0041] The bottom shell locking structure 7 includes a locking rod, a stop hook, a rotating torsion spring, a reinforcing rib, a locking disc and a connecting ring. The rotating torsion spring is fixed at the middle position of the cup holder bottom cover 3. The locking disc is rotatably connected to the cup holder bottom cover 3 and the locking disc abuts against the free end of the rotating torsion spring. The connecting ring and the locking disc are coaxially arranged with the cup holder bottom cover 3. One end of the reinforcing rib is connected to the locking disc and the other end is connected to the connecting ring. One end of the stop hook is connected to the locking disc and the other end is connected to the connecting ring. One end of the locking rod is connected to the connecting ring. A tray 2 locking hook cooperating with the stop hook is provided on the tray base 5, and the tray 2 locking hook can be hooked with the stop hook. A pushing inclined surface is provided at one end of the unlocking rod 42 away from the button block 43, and a driven inclined surface is correspondingly provided on the locking rod. The pushing inclined surface and the driven inclined surface are arranged in parallel.

[0042] As for how the specific structures of the unlocking button assembly 4 and the bottom shell lock structure 7 cooperate, please refer to the specific content of the patent with publication number CN110843633A, and no further details will be given here. It should be noted that the cooperation process of the unlocking button assembly 4 and the bottom shell lock structure 7 in this embodiment is similar to the logic in the patent with publication number CN110843633A, both of which trigger the locking rod by controlling the unlocking rod, but the triggering process is different. The difference is that the unlocking button assembly 4 in the patent with publication number CN110843633A is composed of several separate components. The structure is complex. The button block 5, button holder 6, and unlocking rod 7 in the unlocking button assembly 4 of the prior patent require the cooperation of the protruding shaft, the first slide groove 61, and the second slide groove 51 to achieve the unlocking button assembly 4 withdrawing from the cup barrel after being subjected to force, thereby triggering the bottom shell lock structure 7 to unlock. Moreover, the movement involved in the triggering process is the horizontal sliding of the protruding shaft relative to the first slide groove 61 and the inclined sliding of the protruding shaft relative to the second slide groove 51 to achieve the unlocking rod 7 pushing the locking rod 22. This requires multiple intermediate transmissions to achieve this. After repeated use, the protruding shaft is easily damaged. The unlocking button assembly 4 of this embodiment is simplified into an integral and interlocking structure, which greatly simplifies the structure. When the unlocking button assembly 4 triggers the bottom shell lock structure 7 to unlock, the button block 41 is subjected to force, and the button holder 43 flips accordingly, directly driving the unlocking rod 42 to push the locking rod.

[0043] The cup bucket 1 is provided with a clamping structure 8. When a liquid container is placed in the storage space, the clamping structure 8 is used to press against the outer wall of the liquid container, thereby improving its stability during vehicle travel. The clamping structure 8 includes a claw, a claw holder, and a return torsion spring. The claw is rotatably connected to the claw holder via a first rotating shaft. The claw holder is rotatably connected to the outer wall of the cup bucket 1 via a second rotating shaft. The return torsion spring is rotatably sleeved on the second rotating shaft. The return torsion spring has two free ends, one of which is disposed in contact with the outer wall of the cup bucket 1, and the other free end abuts the claw. The cup bucket 1 is provided with a first extension slot and a second extension slot. The claw is located in the first extension slot and extends into the cup bucket 1. The claw holder, the end away from the claw, is located in the second extension slot and extends into the cup bucket 1.

[0044] As for how the specific structures in the clamping structure 8 cooperate, please refer to the specific content in the patent publication number CN110843633A, which will not be described in detail here.

[0045] After the liquid container is taken out of the storage space, the cup holder is no longer in use. The user presses the unlock button assembly 4 to separate the unlock button assembly 4 from the bottom shell lock structure 7, so that the cup holder bottom cover 3 loses its restriction on the tray base 5. After the tray base 5 loses its restriction, it can be driven by the power lifting assembly 6 to perform a lifting movement away from the cup holder bottom cover 3.

[0046] Combination Figures 4 to 6 Figures 4 to 6 , to improve the stability of the upward movement of the tray 2 relative to the bottom cover 3 of the cup holder, the power boosting assembly 6 includes a fixed outer housing 61, a rotating inner housing 62, a scroll spring 63, a spring rotating shaft 64, a driving ring gear 65, a transmission gear set 66, and a guiding rack. The fixed outer housing 61 is fixedly arranged in the cavity. The fixed outer housing 61, the rotating inner housing 62, and the spring rotating shaft 64 are arranged coaxially from outside to inside. The spring rotating shaft 64 is linked with the rotating inner housing 62, and the rotating inner housing 62 can rotate relative to the fixed outer housing 61. The scroll spring 63 is arranged coaxially on the rotating inner housing 62. The fixed end of the scroll spring 63 is limited and installed on the spring rotating shaft 64. Specifically, the spring rotating shaft 64 forms a clamping gap 9 in the radial direction, and the size of the clamping gap 9 is adapted to the fixed end of the scroll spring 63. The fixed end of the scroll spring 63 is inserted into the clamping gap 9, while the torque end of the scroll spring 63 is limited and installed on the fixed outer housing 61. When the elastic potential energy stored in the scroll spring 63 is the largest, the tray 2 is at the bottom of the cup barrel 1 to form a storage space for placing cups.

[0047] An installation space is formed between the fixed outer housing 61 and the rotating inner housing 62. A driving ring gear 65 linked with the rotating inner housing 62 is arranged in the installation space. The transmission gear set 66 includes a connecting rod 661 and two synchronously moving outer gears 662 and inner gears 663. The inner gear 663 is meshed with the driving ring gear 65. The outer gear 662 is meshed with a guiding rack. All the guiding racks are vertically arranged on the cup barrel 1. In the figure, the guiding racks are blocked by an external light-shielding plate. A plurality of limiting grooves 10 are wound around the fixed outer housing 61. The connecting rod 661 is clamped with the limiting grooves 10. The outer gear 662 and the inner gear 663 are respectively arranged at both ends of the connecting rod 661.

[0048] When the elastic potential energy stored in the scroll spring 63 is released, the generated elastic force drives the spring rotating shaft 64 and the rotating inner housing 62 to rotate synchronously. Then the driving ring gear 65 will rotate relative to the fixed outer housing 61 along with the rotating inner housing 62. Due to the rotation of the driving ring gear 65, the inner gear 663 rotates accordingly, and the outer gear 662 also rotates along with the inner gear 663. At the same time, under the guiding action of the guiding rack, the outer gear 662 moves upward along the path of the guiding rack until the tray 2 stops moving and is stationary. The next time when a cup needs to be placed again, just press the tray 2 until the unlocking button assembly 4 on the tray base 5 and the bottom shell lock structure 7 on the bottom cover 3 of the cup holder are linked again, so that the tray 2 and the tray base 5 are fixed at the bottom of the whole cup holder, facilitating the placement of the cup in the storage space.

[0049] In summary, the power lifting mechanism in the entire device is basically installed in the cavity, making full use of the space of the cavity, making the movement smoother, and reducing the occupation of external space. The coordination between the spiral spring 63, the spring rotating shaft 64, the active ring gear 65, the transmission gear set 66, and the guide rack improves the balance of the up and down movement of the tray 2 and the tray base 5, and realizes the hovering stability of the tray 2.

[0050] Compared with the rotating gear, first rack, energy storage driving gear, energy storage driven gear, power shaft and energy storage torsion spring in the power lifting assembly 6 in the patent with publication number CN110843633A, the energy storage torsion spring in the disclosed patent is used as a power source, and its position is set on the side close to the edge of the cup barrel 1, that is, it is in an eccentric position compared to the cup barrel 1, and the movement axis of the energy storage torsion spring, energy storage driving gear, energy storage driven gear and power shaft when working is perpendicular to the movement path of the rotating gear, that is, it is perpendicular to the movement direction of the tray 2 and the axial direction of the cup barrel 1. Moreover, the power lifting assembly 6 also includes an auxiliary shaft, an auxiliary gear and a second rack. The auxiliary gear has no power when moving. Although the damping generated by the rotary damper on the auxiliary gear plays a certain buffering role during the rising process of the tray 2, it will also affect the overall movement speed of the tray 2 and reduce the user experience.

[0051] like Figure 5 As shown, in this optimized embodiment, four transmission gear sets 66 are correspondingly disposed on the active ring gear 65, and the four transmission gear sets 66 are evenly spaced around the central axis of the fixed outer shell 61. By arranging the fixed outer shell 61, the rotating inner shell 62, and the active ring gear 65, when the rotating inner shell 62 rotates, the active ring gear 65 can drive all the transmission gear sets 66 and simultaneously guide and buffer the lifting and lowering movement of the tray 2. The axis of motion of the scroll spring 63, the rotating inner shell 62, and the active ring gear 65 is coaxial with the entire cup holder, and the motion path of the transmission gear set 66 is also parallel to the axis of the cup holder. The scroll spring 63 serves as the power source for the tray 2 to rise along the axial direction of the cup holder, minimizing power loss caused by changes in direction and angle during transmission. At the same time, the characteristics of the scroll spring 63 also ensure a buffering effect during the tray 2's ascent.

[0052] The power lifting assembly 6 also includes a buffer damper 67, which is coaxially arranged on the fixed outer shell 61 and is located in the installation space. The buffer damper 67 cooperates with the rotating inner shell 62. When the tray 2 and the tray base 5 move upward after being unlocked, the damping effect generated by the buffer damper 67 and the power applied by the spiral spring 63 are balanced, so that the tray 2 can achieve a stable movement similar to a uniform speed, that is, the hovering stability of the tray 2 is further improved. Figure 6As shown in the figure, to further improve the stability of the liquid container, the tray 2 includes an upper cover plate 21, a middle anti-slip plate 22, and a lower fastening plate 23 that are sequentially attached. The middle anti-slip plate 22 forms anti-slip protruding strips 221 on the upper surface of the upper cover plate 21, and a plurality of anti-slip protruding strips 221 are evenly wound around the center of the tray 2. The upper cover plate 21 and the middle anti-slip plate 22 cooperate to play a role in stabilizing and strengthening the cups to be placed on the tray 2. On the side of the lower fastening plate 23 facing away from the middle anti-slip plate 22, there is a hook block 231, and a locking block 611 is formed on the outer wall of the fixed outer casing 61 corresponding to the hook block 231. The hook block 231 and the locking block 611 are detachably hooked. The lower fastening plate 23 realizes the detachable setting of the tray 2 on the fixed outer casing 61 through the cooperation of the hook block 231 and the locking block 611, which is convenient for installation and replacement.

[0053] Optimally, in the present invention, two cup holders can be arranged side by side. The upper and lower ends between the two cup holders are integrally connected. When in use, after the two cup holders are assembled at a preset position inside the vehicle, it is convenient for different users to place two liquid containers simultaneously, improving the applicability.

[0054] The working process of the present invention is as follows:

[0055] When a cup needs to be placed, the cup is placed in the storage space, so that the tray 2 holds up the cup and the claw abuts against the cup. At this time, the stop hook is hooked to the lock hook of the tray 2. When the tray 2 is not in use, the user presses the button block 41, so that the unlocking rod 42 moves along the axial direction of the cup barrel 1 towards the bottom cover 3 of the cup holder. The pushing inclined surface of the unlocking rod 42 pushes the driven inclined surface, causing the locking rod to rotate, and the stop hook is disengaged from the lock hook of the tray 2, so that the tray base 5 is separated from the locking rod. At this time, the tray 2 is in a free state, and the elastic potential energy stored in the scroll spring 63 is released, and the generated elastic force drives the spring rotating shaft 64 and the rotating inner casing 62 to rotate synchronously. The driving ring gear 65 will then rotate relative to the fixed outer casing 61 along with the rotating inner casing 62. Since the driving ring gear 65 rotates, the internal gear 663 rotates accordingly, and the external gear 662 also rotates along with the internal gear 663. At the same time, under the guiding action of the guiding rack, the external gear 662 moves upward along the path of the guiding rack. Under the buffering action of the buffer damper 67, the tray 2 and the tray base 5 are gradually moved away from the bottom cover 3 of the cup holder. The tray 2 pushes the end of the claw holder, causing the claw holder to rotate and drive the claw to disengage from the first protruding groove.
