[0002] As the number of cars continues to increase, people's requirements for vehicle comfort are also constantly improving. The interior components of a car must not only meet people's basic daily needs, but also be easy to operate and not take up space.

[0003] Car cup holders are important supporting accessories in automobiles, used to hold water cups or other beverage containers, greatly solving the problem of where to place drinking containers. Most existing car cup holders are either exposed recesses or have a lid hanging on the outside, making it inconvenient to retrieve the cup. Some lift-type cup holders use an electric mechanism to raise and lower the lid after the cup is placed on it, moving the cup inside. However, these lift-type cup holders may have the following drawbacks: 1. Prolonged use drains the car's battery, and the need for wiring at the bottom of the cup holder increases costs. There is also a risk of leakage, potentially causing accidents and compromising safety. 2. During driving, the inevitable shaking can cause the cup to collide with the inner wall of the cup holder, damaging it. 3. Existing lift-type cup holders only allow the lid to be positioned at the bottom of the cup holder, making it difficult to adjust the lid's position for cups of different heights, resulting in inconvenience.

[0038] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0039] See Figure 1-13 This invention provides a height-adjustable cup holder, comprising:

[0040] Cup holder cover 1, for placing water cups;

[0041] The cup holder housing 2 is located on the outside of the cup holder cover plate 1; the lifting housing 3 is connected to the cup holder housing 2, and a rack is fixedly provided on the inner wall, with a bevel gear 31 meshing inside the rack;

[0042] The gear box assembly 4 includes a gear disk 41, a gear column 42, a coil spring housing 44, and a clamping member 45. The surface of the gear disk 41 meshes with one end of the bevel gear 31, and a coil spring is provided inside the coil spring housing 44.

[0043] Adjustment component 5 includes steel pin 50, movable rod 51 and contact block 54. Contact block 54 is fixedly provided on the inner wall of movable rod 51. Steel pin 50 includes positioning steel pin and movable steel pin. Positioning steel pin passes through gear box assembly 4 and extends into the inside of gear box assembly 4. Movable rod is slidably connected to contact block 54.

[0044] Limiting component 6 is used to clamp the water cup. The limiting component 6 includes a movable frame 61, a clamping seat 62 and a movable column 63. The clamping seat 62 and the movable column 63 are respectively disposed inside the movable frame 61.

[0045] The cup holder bottom cover 7 includes a shock-absorbing damping 70, a locking member 71, and a slot member 701. The locking member 71 includes a locking groove 711 and a positioning plate 714. The locking groove 711 matches the clamping member 45.

[0046] The unlocking component 8 includes a locking bracket 81, an unlocking switch 83, and an unlocking button 85. The unlocking switch 83 and the unlocking button 85 are respectively located at both ends of the locking bracket 81, and the unlocking switch 83 is matched with the positioning plate 714.

[0047] This embodiment provides a lifting cup holder, which includes a cup holder housing 2, a lifting housing 3, a gear box assembly 4, an adjusting assembly 5, a limiting assembly 6, a cup holder bottom cover 7, and a locking assembly 8. After the cup is placed on top of the cup holder cover 1, the cup holder cover 1 is pressed down. The gear box assembly 4 moves downward inside the cup holder housing 2. During the descent of the gear box assembly 4, the gear disk 41 works to drive one end of the bevel gear 31 to rotate. The other end of the bevel gear 31 moves downward in the rack inside the lifting housing 3. During the descent, the steel pin 50 of the adjusting assembly 5 moves downward with the gear box assembly 4 and contacts the contact block 54, providing resistance to the gear box assembly 4. After passing the contact block 54, the steel pin 50 will be locked at the position between the next contact block 54. After applying a greater force to the gear box assembly 4, the steel pin 50 will move downward again. Thus, the gear box assembly 4 can be positioned at different heights during the descent, realizing multi-level adjustment. When the gear box assembly 4 descends close to the cup holder bottom cover 7, the movable column 63 of the limiting assembly 6 is affected by the gear box assembly. As component 4 is pressed outward, the clamping seat 62 at the top of the movable frame 63 moves inward, locking and limiting the water cup on the surface of the cup holder cover 1. When the gear box assembly 4 moves to the bottom of the cup holder housing 2, the clamping component 45 enters the locking groove 711. At the same time, the unlocking switch 83 pushes the locking component 71 inward to insert the insert plate 713 into the slot component 701, limiting the position of the clamping component 45 and ensuring that the gear box assembly 4 does not shake. When the unlocking button 85 is pressed, the torsion spring 84 is pressed inward and after being pressed... The reaction force is applied outward, causing the unlocking switch 83 to move outward. The locking component 71 moves accordingly to unlock, and then the gear box assembly 4 can rise and reset. This cup holder can achieve stable lifting and lowering through a simple mechanical structure. It can adjust the lifting position in multiple positions, making it more practical and cost-effective. It can also lock the cup tightly to prevent it from tipping over due to excessive shaking during car driving, thus providing protection. In addition, it is stable after positioning and easy to unlock, making it more convenient to use.

[0048] In a further embodiment of this invention, the cup holder cover 1 is snapped onto the top of the gear box assembly 4, and elastic strips 101 are uniformly provided on the top surface of the cup holder cover 1.

[0049] In this embodiment, the elastic strip 101 can support the water cup or beverage bottle from the bottom, preventing the water cup from rubbing against the cup holder shell 2 while the vehicle is in motion.

[0050] In a further embodiment of this invention, the number of lifting housings 3 is set to multiple, and the multiple lifting housings 3 are evenly arranged on the outer wall of the cup holder housing 2.

[0051] In this embodiment, the two ends of the bevel gear 31 inside the lifting housing 3 move in the rack and on the gear plate 41 respectively. The multiple bevel gears 31 and the lifting housing 3 can keep the gear box assembly 4 more stable as a whole.

[0052] In a further embodiment of this invention, the gearbox assembly 4 further includes a damper 43, a gearbox bottom cover 401, a gearbox top cover 402, a top cover through groove 403, and a bottom cover protrusion 404. The gearbox bottom cover 401 is disposed on the outside of the coil spring housing 44, the gearbox top cover 402 is disposed on the outside of the gear post 42, the top of the gearbox top cover 402 is provided with a top cover through groove 403, a protective housing 421 is provided around the outside of the gear post 42, the protective housing 421 is disposed on the inside of the gearbox top cover 402, a through hole is provided on one side of the top cover through groove 403, the damper 43 is disposed inside the through hole, and the bottom of the gearbox bottom cover 401 is provided with a bottom cover protrusion 404.

[0053] In this embodiment, the gear disk 41 drives the gear column 42 to rotate during the rotation process. During the rotation process, the top of the gear column 42 moves relative to the bottom of the damper 43, which can ensure a smoother descent process.

[0054] In a further embodiment of this invention, the gear box bottom cover 401 is provided with a steel pin groove that matches the steel pin 50, and the gear box bottom cover 401 is also provided with a plurality of bevel gear grooves that match the bevel gear 31. One end of the bevel gear 31 passes through the gear groove and meshes with the gear disk 41. The gear post 42 passes through the gear disk 41 and extends into the inside of the coil spring housing 44. The coil spring is arranged around the outside of the gear post 42, and one end of the coil spring is fixedly connected to the gear post 42.

[0055] In this embodiment, during the downward movement of the gearbox assembly 4, the gear disk 41 rotates laterally inside the gearbox top cover 402. The coil spring inside the coil spring housing 44 tightens as the gear column 42 rotates. When the gearbox assembly 4 is raised, the force applied to the gearbox assembly 4 from the top is released, the coil spring resets and drives the gear column 42 to rotate in the opposite direction, and the gear disk 41 also rotates in the opposite direction. The bevel gear 31 moves upward inside the rack to achieve automatic lifting.

[0056] In a further embodiment of this invention, the adjusting component 5 further includes a fixed rod 52 and a positioning rod 53.

[0057] In this embodiment, the movable steel pin of the steel pin 50 is in contact with the contact block 54 during the lifting and lowering process. Multiple sets of contact blocks 54 between the positioning rod 53 and the contact block 54 provide resistance. The top end of the movable steel pin will gradually move backward. When the pressure increases, the positioning steel pin enters the next active space through the contact block 44 area. The top end of the movable steel pin is reset, and the positioning steel pin and gear box assembly 4 lift and lower normally. Multiple reinforcing blocks 55 are selectively installed at the bottom and top of the contact block 54 according to different models of cup holders. This can increase the resistance between the steel pin and the contact block 54, making the overall structure more compact and increasing the overall pressure resistance.

[0061] In this embodiment, the locking member 45 enters the locking groove 711, and at the same time, the unlocking switch 83 pushes the locking member 71 to move inward, inserting the insert plate 713 into the slot member 701, limiting the position of the locking member 45 and ensuring that the gear box assembly 4 will not shake. When the unlocking button 85 is pressed, the torsion spring 84 presses inward and provides a reaction force to the outside after being pressed, driving the unlocking switch 83 to move outward, and the locking member 71 moves accordingly to unlock. After being positioned, the locking is stable, and unlocking is convenient, making it more convenient to use.

[0062] In a further embodiment of this invention, a locking groove 711 is provided through the locking member 71, and the clamping member 45 matches the locking groove 711.
