Technical Field
[0001] This utility model relates to the field of cup holders, and in particular to a cup holder claw structure and a cup holder assembly. Background Technology
[0002] Existing linkage-type cup holder structures mostly achieve the linkage opening and closing between the claws through the cooperation of gears and torsion springs. This structure has low durability, and after long-term use, problems such as wear between plastic teeth, tooth surface adhesion, fatigue pitting, tooth breakage, and plastic deformation of the tooth surface occur, resulting in increased clearance between parts and affecting the user experience. On the other hand, due to the weak clamping force of the single torsion spring, this design also causes abnormal noises in cars on bumpy roads. Utility Model Content

[0032] Figure 1 The overall structure of this cup holder assembly and the cup holder claws arranged in the cup holder assembly is shown. It mainly includes a pop-out mechanism 200 that can slide longitudinally back and forth in the housing 100, and a claw mechanism 300 that opens and closes as it slides in the pop-out mechanism 200.
[0033] Reference Figure 2 The jaw mechanism 300 includes a first half-jaw 310 and a second half-jaw 320 rotatably disposed at the jaw mounting position 210. The first half-jaw 310 and the second half-jaw 320 are connected to the telescopic link 330 through a keyway-type sliding connection structure via a first half-jaw sliding groove 311 and a second half-jaw sliding groove 321 at one end, achieving synchronous rotational opening and closing. The telescopic link 330 is fixedly connected to the ejection mechanism 200 through an elastic telescopic part 336, which always provides a reverse pulling force to the first half-jaw 310 and the second half-jaw 320, keeping the first half-jaw 310 and the second half-jaw 320 tending to move towards each other and clamp.
[0034] Specifically, the first half-claw 310 and the second half-claw 320 are rotatably fixed to the pop-out mechanism 200. The telescopic link 330 is pinned into the first half-claw groove 331 and the second half-claw groove 321 through the first mounting shaft 333 extending from the end to achieve a keyway sliding connection. The first half-claw groove 331 and the second half-claw groove 321 are arc-shaped grooves that are radially opposite to each other. Therefore, when one side of the first half-claw 310 and / or the second half-claw 320 rotates, the first mounting shaft 333 is used to achieve synchronous opening and closing.
[0035] Reference Figure 3 The first half-claw 310 is an active kinematic pair, and a guide pin 312 is provided at the end of the first half-claw 310, which is inserted upward into the housing slide groove 110. The housing slide groove 110 can be divided into a first section 111 parallel to the sliding direction of the ejection mechanism 200; a second section 112 and a third section 113 extending away from the first half-claw 310 relative to the first section 111; wherein the first sidewall 110a of the third section 113 is further away from the second sidewall 113b, so that the width of the slide groove (viewed from the top direction) is expanded in a trumpet shape, and the width of the groove of the third section 113 (the distance between the first sidewall 110a and the second sidewall 110b) is greater than that of the second section 112.
[0036] Figures 4a to 4bThe diagram illustrates the relationship between the components of the claw mechanism during its opening and closing. When the ejection mechanism 200 is fully retracted into the housing 100, the guide pin 312 is located at the end of the first section 111, and the first mounting shaft 333 is located at the inner ends of the first half-claw groove 331 and the second half-claw groove 321. The first half-claw 310 and the second half-claw 320 are in a fully closed state. When the ejection mechanism 200 extends from the housing 100, the guide pin 312 moves along the second section 112 into the third section 113, causing the first half-claw 310 to rotate clockwise. The second half-claw 320 rotates counterclockwise synchronously under the influence of the first mounting shaft 333, and the telescopic connecting rod 330 extends accordingly. When a water cup is inserted into the chuck mechanism 300, the first half-claw 310 and the second half-claw 320 further open, and the guide pin 312 moves towards the first sidewall 110a within the unrestricted position of the third segment 113. The first mounting shaft 333 extends to the outer ends of the first half-claw groove 331 and the second half-claw groove 321, and the telescopic link 330 further extends. The telescopic link 330, through the first mounting shaft 333, constantly pulls the first half-claw 310 and the second half-claw 320 backward, ensuring that the first half-claw 310 and the second half-claw 320 remain tight and do not vibrate when unloaded, and that the cup is always clamped when inserted.
[0037] Figures 5 to 7 The connection structure of the telescopic link 330 is shown. The telescopic link 330 has a first limiting convex shaft 331 extending laterally and a second limiting convex shaft 332 extending vertically. Correspondingly, a first limiting groove 220 for accommodating the first limiting convex shaft 331 and a second limiting groove 220 for accommodating the second limiting convex shaft 332 are provided within the pop-up mechanism 200. The telescopic link 330 is suspended and movable within the pop-up mechanism 200, and therefore swings slightly along the designed path under the cross-shaped limiting structure formed by the first limiting convex shaft 331 and the second limiting convex shaft 332.
[0038] In some embodiments, the elastic telescopic part 336 is a helical spring that is hung between the telescopic link 330 and the pop-out mechanism 200 via the hanging point 335. When the telescopic link 330 is pulled forward, the helical spring extends, and vice versa.
[0039] In some embodiments, a second mounting shaft 334 is also provided at the bottom of the telescopic link 330. The first half-claw groove 331 is sleeved on the first mounting shaft 333, and the second half-claw groove 321 is sleeved on the second mounting shaft 334. The upper and lower mounting structure can prevent the telescopic link 330 from deflecting due to uneven force.
[0040] In some embodiments, an upper cover 340 is also provided on the upper part of the first half claw 310, and the guide pin 312 passes through the upper cover guide groove 341 that restricts the rotation path of the guide pin 312 and then inserts into the housing slide groove 110.
[0041] In some embodiments, torsion springs 313 and 323 are provided between the first half-claw 310, the second half-claw 320 and the ejection mechanism 200 to assist the first half-claw 310 and the second half-claw 320 in rebounding.
[0042] In some embodiments, the bottom of the pop-out mechanism 200 is also provided with an elastic anti-collision body 201. When the pop-out mechanism 200 is in the maximum stroke position, the elastic anti-collision body 201 is a limiting component that contacts the housing 100 to prevent hard point impacts and abnormal noises.
