Description

Technical Field

[0001] The invention belongs to the technical field of automobile interior decoration, and particularly relates to a pop-up cup holder structure that can be opened twice synchronously. Background Art

[0002] As the automotive industry progresses toward electrification and intelligent driving, vehicle instrument panels (center consoles) are increasingly adopting thin, flat, and minimalist designs to reduce vehicle energy consumption, reduce weight, and expand passenger compartment space. This design constraint limits the vertical depth available for functional components within the instrument panel, while the demand for in-vehicle comfort and convenience features (such as cup holders for drivers and passengers) is growing.

[0003] Most existing pop-up cup holders utilize single-stage slides or folding mechanisms, resulting in a relatively long and thick overall structure, requiring a deep mounting cavity. Forcibly installing them on thin dashboards often results in partial panel bulges or disrupts the continuity of the design, compromising both the aesthetics and structural strength of the interior. Furthermore, traditional solutions typically only eject once, failing to simultaneously meet the requirements for both support area and clamping stability within a limited travel range. This limits their adaptability to various cup shapes (particularly tall cups or large-diameter bottles). Furthermore, due to the insufficient ejection travel, some products require users to manually deploy the base or clamping arms, resulting in a poor user experience.

[0004] Therefore, how to develop a pop-up cup holder device with a compact structure within the extremely limited layout space of the dashboard, which can provide sufficient support and clamping space through synchronous staged expansion and remain flush with the dashboard surface when closed, has become a technical problem that needs to be solved urgently by technical personnel in this field. Summary of the Invention

[0005] The purpose of the present invention is to solve the deficiencies of the above-mentioned background technology and to provide a pop-up cup holder structure that can be opened twice synchronously.

[0006] The technical solution adopted by the present invention is: a pop-up cup holder structure that can be opened synchronously twice, including a cup holder base, a cup holder upper cover, a first-level opening cup holder bracket, a second-level opening cup holder bracket, a cup holder bottom bracket, a cup holder clamping piece, a cup holder clamping torsion spring, and a cup holder panel. The cup holder base and the cup holder upper cover are fixedly connected by upper and lower clips and fixed to the instrument panel. A first-level opening cup holder bracket is provided in a closed cavity formed by the cup holder base and the cup holder upper cover. The first-level opening cup holder bracket can slide back and forth along the left and right slide rail guide grooves of the closed cavity. The second-level opening cup holder bracket is slidably installed in the left and right slide rail guide grooves of the first-level opening cup holder bracket. The second-level opening cup holder bracket can slide forward and backward along the guide grooves. The second-level opening cup holder bracket is provided with a cup holder bottom bracket which can rotate in a horizontal direction at the bottom thereof. When the cup holder bottom bracket is rotated to be flush with the bottom surface of the second-level opening cup holder bracket, the cup holder bottom bracket can slide back and forth in the guide groove of the first-level opening cup holder bracket along with the second-level opening cup holder bracket. The cup holder clamping piece and the cup holder clamping torsion spring are arranged at the bottom of the second-level opening cup holder bracket. The cup holder clamping piece is attached to the bottom surface of the second-level opening cup holder bracket under the action of the cup holder clamping torsion spring and can slide in the guide groove of the first-level opening cup holder bracket along with the second-level opening cup holder bracket. The cup holder panel is fixed to the second-level opening cup holder bracket by a buckle.

[0007] Preferably, a driving coil spring is provided at one end of the first-stage opening cup holder bracket, a coil spring shaft of the driving coil spring is fixed to the first-stage opening cup holder bracket, and a steel sheet of the driving coil spring is fixed to the cup holder base.

[0008] Preferably, a damping gear is provided on one side of the first-stage opening cup holder bracket, and the damping gear is engaged with a rack on the cup holder upper cover.

[0009] Preferably, a driving gear is provided on the other side of the first-stage opening cup holder bracket, and the driving gear consists of two coaxially arranged gears, the upper gear meshing with the rack on the cup holder upper cover, and the lower gear meshing with the idler gear installed on the first-stage opening cup holder bracket; the idler gear meshing with the rack on the second-stage opening cup holder bracket.

[0010] More preferably, the idler gear and the upper gear of the driving gear have the same number of teeth, and the lower gear of the driving gear has less teeth than the upper gear.

[0011] Preferably, a cup holder bottom bracket torsion spring is provided on one side of the secondary opening cup holder bracket, one end of the bracket torsion spring is fixed to the secondary opening cup holder bracket, and the other end is fixed to the cup holder bottom bracket.

[0012] More preferably, a locking member, a secret lock, is provided on the cup holder base, and a stop pin engaged with the secret lock is provided on the secondary opening cup holder bracket.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The present invention utilizes different numbers of gear teeth to change the transmission ratio, so that one driving force can drive the two brackets to open synchronously. The mechanism structure is cleverly and reasonably arranged, the operation is smooth and reliable, and the space occupied is small, thereby solving the problem of arranging the pop-up cup holder function in a small space; it can improve the interior configuration grade of the vehicle and the comfortable driving experience.

[0014] By introducing a composite mechanism of "primary sliding + secondary sliding + rotating base" within a thin instrument panel, the present invention reduces the vertical depth of the cup holder in the closed state to approximately half that of a conventional structure, maintaining a flush appearance between the panel and the instrument panel. When opened, a rigid transmission mechanism of a coil spring, gear, and idler pulley drives the primary and secondary brackets to extend synchronously according to a predetermined transmission ratio, while the base bracket rotates and unfolds accordingly. This ensures sufficient support length while avoiding manual deployment by the user, ensuring smooth operation. A damping gear cushions the coil spring drive, significantly reducing transient shock and noise, and extending the life of the mechanism. The coordinated action of a stop pin and a secret lock ensures that the cup holder is securely positioned at both the retracted and extended ends, preventing malfunctions caused by driving vibration. The clamping member, under the continuous elastic force of the torsion spring, provides a firm lateral restraint for containers of varying diameters, enhancing stability on bumpy roads. Overall, the present invention achieves the advantages of compact size, rapid deployment, smooth operation, and reliable locking within a limited installation space, significantly improving the shortcomings of existing in-vehicle cup holders in terms of appearance, layout, ease of use, and durability, and possesses high practical value and potential for widespread adoption.

DETAILED DESCRIPTION

[0017] The following is a further description of specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is intended to facilitate understanding of the present invention and does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0018] like Figure 1 As shown, two cup holders of the present invention are arranged parallel to the underside of the central control screen on the instrument panel 2. One cup holder (1a) is in the practical, open position, while the other (1b) is in the closed position. Compared to conventional pop-up cup holders, the present invention is smaller in overall length and concealed within the instrument panel 2 when not in use. Its exterior surface is flush with the instrument panel's design, contributing to a harmonious and streamlined dashboard design. To unlock the cup holder, press the cup holder's surface, and the cup holder automatically pops out and simultaneously opens again, allowing for cups, beverage bottles, and other items to be placed there.

[0019] like Figure 2 As shown, the cup holder structure 1 of the present invention includes a cup holder base 1.1, a cup holder upper cover 1.2, a first-stage opening cup holder bracket 1.3, a second-stage opening cup holder bracket 1.4, a driving coil spring 1.5, a driving gear 1.6, an idler gear 1.7, a cup holder bottom bracket 1.8, a cup holder clamping member 1.9, a cup holder clamping torsion spring 1.10, a cup holder panel 1.11, a cup holder bottom bracket torsion spring 1.12, a damping gear 1.13 and a secret lock 1.14.

[0020] like Figure 3 — Figure 7As shown, the cup holder base 1.1 and the cup holder cover 1.2 are fixedly connected by upper and lower buckles and fixed to the instrument panel 2 by screws and clips. A first-level opening cup holder bracket 1.3 is provided in the closed cavity formed by the cup holder base 1.1 and the cup holder cover 1.2. The first-level opening cup holder bracket 1.3 can slide back and forth along the left and right slide rail guide grooves of the closed cavity. A second-level opening cup holder bracket 1.4 is slidably installed in the left and right slide rail guide grooves of the first-level opening cup holder bracket 1.3. The second-level opening cup holder bracket 1.4 can slide back and forth along the guide groove. A cup holder bottom bracket 1.8 that can rotate around the horizontal direction is installed at the bottom of the second-level opening cup holder bracket 1.4. When the cup holder bottom bracket 1.8 is rotated until it is flush with the bottom surface of the second-stage cup holder bracket 1.4, it can slide back and forth with the second-stage cup holder bracket 1.4 in the guide groove of the first-stage cup holder bracket 1.3. A cup holder clamp 1.9 and a cup holder clamping torsion spring 1.10 are located at the bottom of the second-stage cup holder bracket 1.4. Driven by the cup holder clamping torsion spring 1.10, the cup holder clamp 1.9 is tightly attached to the bottom surface of the second-stage cup holder bracket 1.4 and can slide with the second-stage cup holder bracket 1.4 in the guide groove of the first-stage cup holder bracket 1.3. The cup holder panel 1.11 is secured to the second-stage cup holder bracket 1.4 via a snap. The cup holder bottom bracket 1.8 and cup holder clamp 1.9 are located at the front and rear ends of the second-stage cup holder bracket 1.4, respectively.

[0021] A driving coil spring 1.5 is provided at one end of the first-stage opening cup holder bracket 1.3. The coil spring shaft of the driving coil spring 1.5 is fixed to the first-stage opening cup holder bracket 1.3. The steel sheet of the driving coil spring 1.5 is fixed to the cup holder base 1.1.

[0022] A damping gear 1.13 is provided on one side of the first-stage opening cup holder bracket 1.3, and the damping gear 1.13 is engaged with a rack on the cup holder upper cover 1.2.

[0023] A drive gear 1.6 is provided on the other side of the first-stage opening cup holder bracket 1.3. The drive gear 1.6 consists of two coaxial gears arranged above and below. The upper gear meshes with the rack on the cup holder upper cover 1.2, and the lower gear meshes with the idler gear 1.7 installed on the first-stage opening cup holder bracket 1.3; the idler gear 1.7 meshes with the rack on the second-stage opening cup holder bracket 1.4.

[0024] The idler gear 1.7 has the same number of teeth as the upper gear of the driving gear 1.6, and the lower gear of the driving gear 1.6 has less teeth than the upper gear.

[0025] A cup holder bottom bracket torsion spring 1.12 is provided on one side of the secondary opening cup holder bracket 1.4. One end of the bracket torsion spring 1.12 is fixed to the secondary opening cup holder bracket 1.4, and the other end is fixed to the cup holder bottom bracket 1.8.

[0026] A locking member, a secret palace lock 1.14, is provided on the cup holder base 1.1, and a stop pin engaged with the secret palace lock 1.14 is provided on the secondary opening cup holder bracket 1.4.

[0027] Among them, the cup holder base 1.1 and the cup holder cover 1.2 are fixed together up and down by their own buckles, and are fixed to the instrument panel 2 by screws and clips; the first-level opening cup holder bracket 1.3 is installed in the left and right slide rail guide grooves in the closed cavity composed of the cup holder base 1.1 and the cup holder cover 1.2, and can slide back and forth in the guide grooves; the second-level opening cup holder bracket 1.4 is installed in the left and right slide rail guide grooves of the first-level opening cup holder bracket 1.3, and can also slide back and forth in the guide grooves; the cup holder bottom bracket 1.8 is installed on the second-level opening cup holder bracket 1.4, and can rotate around its own axis left and right, rotating close to the second-level opening. After the cup holder bracket 1.4 is opened, it can slide back and forth in the guide groove of the first-stage cup holder bracket 1.3 together with the second-stage cup holder bracket 1.4; the cup holder clamping piece 1.9 and the cup holder clamping torsion spring 1.10 are installed together on the bottom surface of the second-stage cup holder bracket 1.4. Under the action of the cup holder clamping torsion spring 1.10, the cup holder clamping piece 1.9 is always attached to the bottom surface of the second-stage cup holder bracket 1.4 and can slide back and forth in the guide groove of the first-stage cup holder bracket 1.3 together with the second-stage cup holder bracket 1.4; the cup holder panel 1.11 is clamped on the second-stage cup holder bracket 1.4 by its own clip.

[0028] The driving force for the first-stage cup holder 1.3 to slide back and forth within the closed guide groove formed by the cup holder base 1.1 and the cup holder cover 1.2 is provided by a drive coil spring 1.5 mounted at the end of the first-stage cup holder 1.3. The drive coil spring 1.5 is affixed to the first-stage cup holder 1.3, and the steel sheet of the drive coil spring 1.5 is fixed to the cup holder base 1.1. To prevent the first-stage cup holder 1.3 from moving suddenly and unsteadily when the drive coil spring 1.5 moves, a damping gear 1.13 mounted on one side of the first-stage cup holder 1.3 meshes with the rack of the cup holder cover 1.2 to ensure smooth operation. A drive gear 1.6 is installed on the first-stage cup holder bracket 1.3 (on the other side of the damping gear 1.13). Drive gear 1.6 consists of two coaxial gears: the upper gear meshes with the rack on the cup holder cover 1.2, while the lower gear meshes with an idler gear 1.7 mounted on the first-stage cup holder bracket 1.3. Idler gear 1.7 meshes with the rack on the second-stage cup holder bracket 1.4. The idler gear 1.7 and the drive gear 1.6 have the same number of teeth on the upper side. By reducing the number of teeth on the lower side of the drive gear, the second-stage cup holder bracket 1.4 moves synchronously with the first-stage cup holder bracket 1.3. For example, if the lower gear has half the number of teeth on the upper gear, the travel of the second-stage cup holder bracket 1.4 will be twice the travel of the first-stage cup holder bracket 1.3.

[0029] When the cup holder is opened, the second-stage cup holder bracket 1.4 runs to the end of its travel. At this time, the rotation axis of the cup holder bottom bracket 1.8 is completely exposed from the guide rail of the first-stage cup holder bracket 1.3. The cup holder bottom bracket 1.8 automatically rotates downward and unfolds under the action of the cup holder bottom bracket torsion spring 1.12. At this time, a water cup or bottle can be placed, with the bottom of the water cup or bottle supported by the cup holder bottom bracket 1.8 and the side pressed tightly by the cup holder clamp 1.9.

[0030] To close the cup holder, you need to manually push the cup holder panel 1.11 inward to store energy in the drive coil spring 1.5, causing the secondary opening cup holder bracket 1.4 to move inward. Under the action of the primary opening cup holder bracket 1.3, the cup holder bottom bracket 1.8 rotates and folds. When the inward movement ends, the stop pin (not shown in the figure) on the secondary opening cup holder bracket 1.4 is locked by the secret lock 1.14 installed on the cup holder base 1.1.

[0031] like Figure 3 As shown, the cup holder structure of the present invention is in a closed state, at which time the stop pin at the bottom of the secondary opening cup holder bracket 1.4 is stuck in the groove of the secret palace lock 1.14 ( Figure 4 shown).

[0032] When the cup holder is opened, it is necessary to push the cup holder panel 1.11 inward to unlock it. At this time, the cup holder opens smoothly outward under the joint action of the accumulated driving coil spring 1.5 and the damping gear 1.13. During the opening process, the driving gear 1.6 installed on the first-level cup holder bracket 1.3 rotates under the drive of the rack on the cup holder cover 1.2. The rotation of the driving gear 1.6 drives the meshed idler gear 1.7 to rotate in the opposite direction. The rotation of the idler gear 1.7 drives the second-level cup holder bracket 1.4 and the first-level cup holder bracket 1.3 to move in the same direction. Due to the different number of gear teeth, the transmission ratio is different. The lower end of the driving gear 1.6 has fewer gear teeth than the upper end. Therefore, when the first-level cup holder bracket 1.3 and the second-level cup holder bracket 1.4 move in the same direction, the second-level cup holder bracket 1.4 runs faster than the first-level cup holder bracket 1.3, thereby achieving the purpose of secondary opening.

[0033] When the cup holder operation is terminated, the first-stage cup holder bracket 1.3 and the cup holder base 1.1 are physically limited at position C, and the second-stage cup holder bracket 1.4 is physically limited at position B of the first-stage cup holder bracket 1.3; at this time, the cup holder bottom bracket 1.8 is completely exposed from the guide rail A of the first-stage cup holder bracket 1.3, and the cup holder bottom bracket 1.8 automatically rotates downward and opens under the action of the cup holder bottom bracket torsion spring 1.12; see Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 .

[0034] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be covered by the scope of protection of the present invention. Matters not described in detail in this specification belong to the prior art known to those skilled in the art.
