Description

Technical Field

[0001] This utility model relates to automotive parts, and more particularly to a lifting cup holder mechanism with a circumferential opening and closing structure. Background Technology

[0002] Most commonly used car cup holder mechanisms are open, roller shutter sliding, or flip-top designs, which affect both the consistency of the appearance of the decorative parts in the cup holder area and the comfort of passengers or drivers when handling cups. Patent document CN209776265U discloses a lifting cup holder for automobiles, which includes a lifting cup holder base, a lifting guide column, an upper housing, a lower housing, a claw assembly, and a locking / unlocking mechanism. The lifting cup holder base is installed in the cavity between the upper and lower housings after engaging with the lifting guide column. The upper and lower housings are connected by screws. The claw assembly and the locking / unlocking mechanism are distributed on the outer side walls of the upper and lower housings. When the cup holder function is activated, cups or beverages can be placed. When the cup holder function is deactivated, the countersunk hole of the cup holder structure is not visible and can be used as a decorative part, optimizing and beautifying the interior. However, this type of lift-up cup holder relies on the cup holder base rising to close, requiring both manual pressing and button activation. Furthermore, a seam remains visible after closing, resulting in insufficient aesthetics and convenience. The clamping range of the clips is fixed, only accommodating small-diameter cups, and the overall structure is bulky, making it difficult to adapt to the increasingly thin and lightweight interiors of automobiles. Therefore, it is necessary to optimize its structure to overcome these shortcomings. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0012] like Figures 1-6 As shown, the lifting cup holder mechanism with a circumferential opening and closing structure proposed in this utility model includes a support frame 100, a bearing cylinder shell 200, and a cup body carrier plate 300. The support frame is installed in the vehicle body, forming an assembly space. The bearing cylinder shell is installed in the support frame, and its axial direction is arranged vertically, forming a cup body receiving space inside the bearing cylinder shell. A clearance guide groove 210 is provided on the side wall of the bearing cylinder shell, which penetrates the inner and outer sides of the bearing cylinder shell radially and extends along the axial direction of the bearing cylinder shell. The cup body carrier plate is located in the bearing cylinder shell and can be lifted and lowered along the axial direction of the bearing cylinder shell, forming a cup body bearing surface on its top. The two ends of the cup body carrier plate are respectively provided with a transmission end head 310 and a guide end head 320, which extend from the clearance guide groove and can move along the clearance guide groove. In this embodiment, a claw assembly 220 is also provided in the bearing cylinder shell, which clamps and positions the side wall of the cup body.

[0013] In one embodiment, the mechanism further includes a bottom ring 410, a top ring 420, a blade 430, a core ring 440, and a connecting rod 450. The bottom ring is mounted on the top of the bearing shell, and the top ring is mounted on the top of the bottom ring, forming a circumferential opening and closing space between them. A set of blades is provided, each located within the circumferential opening and closing space between the top and bottom rings, and arranged sequentially along the circumference of the bearing shell. These blades can deflect within the circumferential opening and closing space, with the width of their inner end being smaller than the width of their outer end. This allows for opening or closing of the opening at the top of the bearing shell, and when closed, they form a sensing through-hole at the inner end. A set of guide grooves 411 are provided in the bottom ring, each extending radially along the bottom ring. A guide post 431 extending into the guide groove is provided at the outer end of each blade. The deflection process of the opening and closing blades is guided by the guide end post and the guide slide. The opening and closing core ring is located between the opening and closing bottom ring and the opening and closing top ring, and cooperates with the power drive assembly.

There is a gap between the inner rotating shaft and the guide end post. When the opening and closing core ring rotates, it drives the opening and closing blade to deflect around the inner rotating shaft as the axis through the opening and closing connecting rods, and moves along the guide slide at the same time. A set of limiting slots 421 are opened at the bottom of the opening and closing top ring. The width of the inner end of the limiting slot is smaller than the width of the outer end. The opening and closing connecting rod is located in the limiting slot, and its movement range is limited by the limiting slot. In this embodiment, each limiting slot is provided with a mating protrusion 422, and the top surface of the opening and closing blade abuts against the mating protrusion to avoid the blade from contacting the opening and closing top ring when it shakes, thereby reducing its frictional resistance when it deflects.

The drive screw is located outside the bearing cylinder shell and extends axially along the bearing cylinder shell. One end of the drive screw engages with the support frame via a rotating structure, and the other end engages with the bearing cylinder shell via a rotating structure, allowing it to rotate between the support frame and the bearing cylinder shell. The transmission end engages with the drive screw via a transmission nut. When the drive screw rotates, it can drive the transmission end and the cup plate to rise or fall. In this embodiment, a guide column 550 is also provided outside the bearing cylinder shell, and this guide column is connected to the drive screw. The guide ends are parallel to each other and are sleeved on the guide columns. During the rising or falling of the cup body carrier plate, the guide columns and guide ends guide it. The drive gear is mounted on the drive screw and can rotate with the drive screw. A driven rack 441 is provided on the side of the opening and closing core ring. The driven rack extends circumferentially along the opening and closing core ring and meshes with the drive gear. When the drive gear rotates, it can drive the opening and closing core ring to rotate through the driven rack, so that the opening and closing blades open or close. The drive motor is installed in the support frame, and its power output shaft cooperates with the drive screw through the gear set. The drive motor drives the drive screw to rotate. In this embodiment, limiting ends 442 are respectively provided at both ends of the driven rack. A limiting notch that cooperates with the limiting end is provided in the bearing shell. The limiting notch and the limiting end limit the deflection range of the opening and closing core ring.

[0015] exist Figure 4In the illustrated embodiment, the power drive assembly includes a drive screw 510, a drive motor 530, and a drive rope 540. The drive screw is located outside the bearing shell and extends axially along the bearing shell. One end of the drive screw is engaged with the support frame via a rotating structure, and the other end is engaged with the bearing shell via a rotating structure, allowing it to rotate between the support frame and the bearing shell. The transmission end is engaged with the drive screw via a transmission nut. When the drive screw rotates, it can drive the transmission end and the cup plate to rise or fall. In this embodiment, a guide column 550 is also provided outside the bearing shell. The guide column is parallel to the drive screw, and the guide end is sleeved on the guide column. During the rising or falling of the cup plate, it is guided by the guide column and the guide end. The drive motor is installed in the support frame, and its power output shaft is engaged with the drive screw via a coupling. The drive motor drives the drive screw to rotate. The drive rope is mounted on the side of the bearing shell via a steering pulley 541. Its upper section extends circumferentially along the bearing shell and engages with the opening and closing core ring. The side wall of the bearing shell has a guide structure that cooperates with the drive rope. The opening and closing core ring is also engaged with the bearing shell via a closing tension spring 542. The pulling direction of the closing tension spring is opposite to that of the drive rope. The lower section of the drive rope extends axially along the bearing shell and engages with the bearing shell via an opening tension spring 543. The drive rope is also provided with a mating end 544 that cooperates with the transmission end. When the cup body plate rises, the transmission end lifts the mating end upward, the opening tension spring extends, and the closing tension spring shortens, driving the opening and closing core ring to close the opening and closing blades. When the cup body plate falls, the opening tension spring shortens, and the drive rope pulls the opening and closing core ring to deflect, opening the opening and closing blades and extending the closing tension spring. The tension of the closing tension spring is greater than that of the opening tension spring.

[0016] In one embodiment, the above-mentioned mechanism further includes an assembly support 610, a micro switch 620, a sensing frame 630, a signal terminal 640, and a sensing end cover 650. The assembly support is installed at the bottom of the cup body carrier plate and corresponds to the position of the sensing through hole. It can rise and fall together with the cup body carrier plate. The micro switch is installed in the assembly support and is electrically connected to the control circuit of the drive motor through a line. It can rise and fall together with the assembly support. The sensing frame is installed in the assembly support through a vertical sliding structure. A return spring 641 is provided between the assembly support and the sensing frame. When the sensing frame descends, its bottom can abut against the micro switch. When it rises, it separates from the micro switch. The signal terminal is installed in the sensing frame and is electrically connected to the control circuit of the drive motor through a line. It can rise and fall together with the sensing frame. In one embodiment, the signal terminal consists of an infrared PCB board and a signal transceiver fixed on the infrared PCB board. The sensing end cover is made of light-transmitting material. It is installed on the top of the sensing frame and covers the signal terminal. The top of the sensing end cover is exposed through the sensing through hole. The signal terminal can send and receive infrared signals from the sensing end cover.

[0017] When the user's hand or the cup body sweeps across the top of the mechanism, the signal terminal is triggered, sending a start signal to the control circuit of the drive motor. The drive motor runs forward, causing the opening and closing blades to deflect and open. Simultaneously, the cup carrier plate descends to the bottom of the supporting cylinder shell, at which point the cup can be placed on the cup carrier plate. When the cup is placed on the cup carrier plate, pressure is applied to the sensing end cover, causing the sensing frame to descend and triggering a microswitch. The microswitch sends a signal to the drive motor, stopping it. The cup carrier plate remains stationary. After the cup is removed, the microswitch resets to the open state. After a set delay, the drive motor runs in reverse, causing the cup carrier plate to rise back to its original position, and the opening and closing blades close simultaneously. The drive motor has built-in position feedback. If the drive motor is not at the 0 point position (defined here as when the cup carrier plate is at its highest position), and the signal terminal is triggered, it is considered a false trigger and no response is made. If the microswitch is triggered during the forward running of the drive motor and the descent of the cup carrier plate, the drive motor continues to perform the descent action. If the microswitch is triggered again during the process of the drive motor rotating in the reverse direction and the cup carrier plate rising, the drive motor will stop and rotate in the forward direction until the cup carrier plate reaches the lowest position, ensuring that the cup can be placed normally.

[0018] This device adopts a completely new design form that differs from traditional cup holders. It uses an independent modular design scheme, which can be installed in different car models and locations. It can save design and experimentation costs and development time. The open modular design structure can be used to update and upgrade the cup holder function. For example, a heating module can be added to the cup body carrier plate to heat the cup body, or a power and data signal line quick-connect plug can be added to the cup body carrier plate to power the smart cup and realize heating and cooling functions.
