[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0022] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments of the present invention, a car cup holder includes a cup holder body 1, a cup holder base 4, and a plurality of cup holder claws 2; The cup holder base 4 is set inside the cup holder body 1 and can move up and down on the cup holder body 1. A return spring 5 is provided between the cup holder base 4 and the cup holder body 1. Multiple cup holder claws 2 are arranged circumferentially along the cup holder body and are slidably connected to the cup holder body 1, so that the cup holder claws can move in the radial direction of the cup holder body. A clamping drive mechanism is provided between the cup holder claw 2 and the cup holder base 4. When the cup holder base is subjected to a downward force and moves downward, the clamping drive mechanism can drive multiple cup holder claws to move simultaneously along the radial direction of the cup holder body toward the center of the cup holder body.

[0023] The cup holder base and the cup holder claws are linked by a clamping drive mechanism, which converts the weight of the cup into the displacement of the cup holder base, and then converts the displacement of the cup holder base into a driving force on the cup holder claws, thereby driving the cup holder claws to clamp the cup, thus facilitating the handling of cups of different sizes and shapes.

[0024] In some embodiments, the clamping drive mechanism includes multiple sets of clamping drive components, each set of clamping drive components corresponding to the driving of a cup holder jaw; such as Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8The clamping drive assembly includes a connecting rod guide 6 and a secondary conversion gear 7. The connecting rod guide 6 is slidably connected to the cup holder body 1 and can move with the cup holder base under the action of the cup holder base. The secondary conversion gear 7 is rotatably connected to the cup holder body 1. A first rack 61 is provided on the connecting rod guide 6, and the connecting rod guide 6 is meshed with the secondary conversion gear 7 through the first rack 61. A transmission rack 12 is provided on the cup holder claw 2, and the secondary conversion gear 7 is meshed with the transmission rack 21.

[0025] When a cup is placed on the cup holder base, the cup drives the cup holder base to move downwards. The cup holder base then drives the connecting rod guide to move downwards. At this time, the first rack drives the second-stage conversion gear to rotate, and the second-stage conversion gear drives the cup holder claws to move inwards towards the cup holder body, thus clamping the cup.

[0026] In some embodiments, the transmission ratio between the first rack 61, the secondary conversion gear 7, and the transmission rack 21 is set to enable the output torque to be greater than the output torque.

[0027] This allows for a greater force to be applied to the cup holder claws even when the cup is relatively light, thus achieving stable clamping of the cup.

[0028] In some embodiments, the connecting rod guide 6 includes an arc-shaped portion 63, a first rack 61 disposed in the arc-shaped portion 63, a secondary conversion gear 7 disposed inside the arc-shaped portion 63, and the arc-shaped portions 63 are respectively disposed on the outer side of the corresponding cup holder claws to optimize the setting of the clamping drive mechanism on the cup holder.

[0029] In some embodiments, a groove 11 is provided on the cup holder body 1, and one end of the connecting rod guide 6 extends into the interior of the cup holder body through the groove and is located below the cup holder base. Through the cooperation with the groove, the connecting rod guide and the cup holder body slide together, and when the cup holder base moves downward, it drives the connecting rod guide to move, realizing the linkage between the two and the overall structure is compact.

[0030] In some embodiments, a damper 3 is provided on the cup holder body 1, and a second rack 62 is provided on the connecting rod guide 6. The connecting rod guide 62 is engaged with the damper 3 through the second rack 62. The damper, through its cooperation with the connecting rod guide, provides buffering for the movement of the connecting rod guide, thereby reducing abnormal noises caused by collisions between the mechanisms when the cup is being placed or removed, and when no cup is placed, further improving the quality of the product.

[0031] The cup holder body is made of PC+ABS material, which is used for the load-bearing capacity of the entire cup holder and for the structural layout and installation of other parts. The cup holder base is made of PC+ABS material.

[0032] The cup holder claws are made of POM material to reduce frictional resistance when picking up and placing cups, and to reduce abnormal noise caused by collisions. The connecting rod guide and the secondary conversion gear are also made of POM material.

They are only used to facilitate the description of this invention and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0034] Furthermore, the use of terms such as "horizontal" and "vertical" in the description of this invention does not imply that the components are required to be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
