Description

Technical Field

[0001] This utility model belongs to the technical field, and in particular relates to a cup holder device. Background Technology

[0002] With the widespread use of smartphones in navigation, communication, and other fields, car phone holders have become an essential accessory in the cockpit. Common mounting methods include suction cup mounting to the windshield and clip mounting to the air conditioning vents. However, these mounting methods have obvious drawbacks: suction cup holders are prone to falling off in extreme temperatures and can obstruct the view; clip holders may block the air vents, affecting air conditioning efficiency and even damaging the vent blades.

[0003] To overcome the aforementioned shortcomings, existing technologies have developed solutions that utilize the inherent structure of the vehicle's driver's area for fixation. For example, a known car phone holder is designed to be fixed in a cup holder within the vehicle. These solutions typically include a base that can be inserted into the cup holder, with elastically opening locking arms on the base. The locking arms, through the elastic deformation of their material, abut against the inner wall of the cup holder, utilizing static friction for fixation. While this design avoids interference with air vents and the driver's view, it also has significant problems: the elastic force of the locking arms depends entirely on the elastic modulus and structural morphology of their manufacturing material. After long-term, repeated use, plastic deformation or fatigue can easily occur, leading to a decrease in clamping force and insecure fixation. Furthermore, the opening angle is small, resulting in poor adaptability to cup holders of different shapes and sizes. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a cup holder device to meet the needs of users.

[0005] To achieve the above objectives, this utility model provides a cup holder device suitable for fixing in a cup holder in the driver's area, comprising a support body and a placement device and an adaptive tensioning mechanism disposed at both ends of the support body; the adaptive tensioning mechanism includes a base, a pivot, an elastic element, and at least a pair of clamps; the clamps are rotatably connected to the base via the pivot; the elastic element acts between the base and the clamps, or between the two clamps, to provide a continuous elastic driving force, driving the outer surface of the clamps to remain open so as to elastically abut against the inner wall of the cup holder, thereby fixing the support body in the cup holder through static friction.

[0006] The bracket body is fixed by the contact between the outer surface of the clip and the upper inner wall of the cup holder. The bracket body and the installation structure only occupy the upper space of the cup holder, and do not affect the function of placing water cups or other items at the bottom of the cup holder, thus achieving efficient use of space.

[0007] Preferably, the clip includes a first side edge and a second side edge disposed opposite to each other, the first side edge being pivotally connected to the pivot, and when the second side edges of the two clips abut against each other, it indicates that the clip has been closed to the minimum opening angle.

[0008] Preferably, the elastic element is a torsion spring, which has a compact structure, stable elasticity, strong fatigue resistance, and can provide uniform driving force for a long time. The torsion spring includes a spring coil, a first leg, and a second leg. The spring coil is sleeved on the pivot, which saves space and ensures that the elastic force is stably transmitted to the spring coil along the axis of the pivot.

[0009] Preferably, each of the pivots is provided with at least two of the torsion springs to provide a uniform elastic driving force to the clamps.

[0010] Preferably, each clamp is pivotally connected to the base via a corresponding pivot, and each pivot is provided with at least one torsion spring. The first leg abuts against the inner surface of the clamp, and the second leg abuts against the inner surface of the base. When the clamp is closed by an external force, the clamp drives the first leg to rotate, causing the spring coil to undergo elastic deformation and store elastic potential energy. Each clamp can independently adjust its opening angle to adapt to scenarios with asymmetrical inner walls of the cup groove (such as irregularly shaped cup grooves), further improving compatibility.

[0011] Preferably, the inner surface of the clamping piece is provided with a first groove for receiving the first leg of the torsion spring; the base is provided with a second groove for receiving the second leg of the torsion spring, so as to prevent the first leg and the second leg from slipping or shifting when the clamping piece rotates, and to ensure stable transmission of elastic force.

[0012] Preferably, the first side edge includes a first stop surface, and the base includes a second stop surface. The first stop surface abuts against the second stop surface to limit further rotation of the clamping piece and to indicate that the clamping piece has rotated to a preset maximum opening angle, so as to prevent the clamping piece from over-expanding and causing the torsion spring to deform beyond its range or even break, thus protecting the elastic element.

[0013] Preferably, the first side edge is provided with a first pivot seat, and the two sides of the base are provided with second pivot seats. The pivot passes through the first pivot seat and the second pivot seat. The second pivot seat is adapted to axially support the first pivot seat. The first pivot seat or the second pivot seat has a relief groove adapted to accommodate the spring ring, making the structure more compact and adapting to the limited space inside the cup groove.

[0014] Preferably, the first side edge has an arc-shaped concave surface on the side facing the base, and the second pivot seat has an arc-shaped convex surface on the side facing the clip that mates with the arc-shaped concave surface. The arc-shaped concave surface and the arc-shaped convex surface are adapted to rotate about the same pivot axis. The first stop surface is integrally formed on one side of the arc-shaped concave surface, and the second stop surface is integrally formed on one side of the arc-shaped convex surface.

[0015] Preferably, both clamping pieces are pivotally connected to the same pivot, which is connected to the base. At least one torsion spring is mounted on the pivot. The first leg abuts against the inner surface of one of the clamping pieces, and the second leg abuts against the inner surface of the other clamping piece. When the clamping pieces are closed by an external force, the two clamping pieces respectively drive the first leg and the second leg to rotate, causing the spring coil to undergo elastic deformation and store elastic potential energy. The torsion spring simultaneously drives the clamping pieces on both sides to open, with symmetrical opening angles, suitable for regular cups such as circles. The linkage structure reduces the number of parts, simplifies assembly, and lowers costs.

[0016] Preferably, the inner surface of the clip is provided with a first slot for receiving the first leg or the second leg.

[0017] Preferably, most cup grooves are circular or near-circular, and the outer surface of the clamping piece is a circumferential surface to adapt to the shape of the inner wall of the cup groove, increase the contact area between the clamping piece and the inner wall of the cup groove, and improve static friction; avoid local stress concentration caused by sharp corner contact, and protect the inner wall of the cup groove, such as avoiding scratches.

[0018] Preferably, the adaptive tensioning mechanism is constructed such that its overall outer surface can form a circumferential surface with the same axis and the same diameter, or its top view projection can form a continuous arc, further improving the fit with the cup groove, especially suitable for deep cup grooves or cup grooves with consistent inner wall curvature, and significantly enhancing the fixing stability.

[0019] Preferably, the outer surface of the clip is covered with an elastic friction layer, wherein: the elastic friction layer is made of silicone or rubber, and the silicone / rubber material has a buffering effect to avoid abnormal noise or damage caused by hard contact between the clip and the cup groove; and / or, the outer surface of the elastic friction layer is provided with a textured surface to greatly increase the static friction with the inner wall of the cup groove and prevent the bracket from sliding due to driving vibration.

[0020] Preferably, the elastic element is a metal spring with elasticity. When the clips are closed, the metal spring bends and deforms to accumulate elastic potential energy. The elastic force of the metal spring restoring its deformation is suitable for pushing the clips open. The two ends of the metal spring can be connected to the two clips respectively, or one end of the metal spring can be connected to the base, and the other end of the metal spring can abut against the inner side of the clips.

[0021] Preferably, the bracket body includes a connecting rod and an adjusting rod, one end of the connecting rod being connected to the placement device; one end of the adjusting rod being connected to the connecting rod, and the other end being connected to the base; wherein, the connecting rod and the adjusting rod are adapted to rotate relative to each other around a first axis, and the adjusting rod and the base are adapted to rotate relative to each other around a second axis, allowing for flexible adjustment of the phone's height and front / back position, avoiding obstruction of the dashboard or interference with gear shifting operations, and the first axis being parallel to the second axis, ensuring the stability of the phone's orientation during adjustment and preventing lateral shifting.

[0022] Preferably, a locking mechanism is provided between the connecting rod and the adjusting rod, and / or a locking mechanism is provided between the adjusting rod and the base. The locking mechanism includes a stud, a nut, and a knob. The nut is disposed on the adjusting rod. One end of the stud extends out of the connecting rod or the base and is connected to the knob. The other end of the stud is adapted to extend into the adjusting rod to be threadedly connected to the nut. The knob is adapted to drive the stud to move axially forward and backward, thereby realizing the clamping or loosening between the connecting rod or the base and the adjusting rod.

[0023] Preferably, the connecting rod and the adjusting rod have meshing first toothed rings on their opposing end faces, the axes of the first toothed rings coinciding with the first axis; the adjusting rod and the base have meshing second toothed rings on their opposing end faces, the axes of the second toothed rings coinciding with the second axis. This design improves the accuracy of angle adjustment by limiting the adjustment accuracy through each tooth corresponding to a fixed angle, while also enhancing the anti-torsional capability after locking, ensuring that the phone does not shift on bumpy roads.

[0024] Preferably, the device is a mobile phone holder including a ball seat, and the end of the connecting rod facing the device is connected to a omnidirectional ball. The omnidirectional ball is rotatably housed in the ball seat and can rotate 360° within the ball seat to achieve multi-directional angle adjustment of the mobile phone and meet the user's personalized needs for navigation viewing angle.

[0025] Preferably, the storage device is a tabletop, and the support body is adapted to support the storage device to form a suspended tabletop. The tabletop and the connecting rod can be connected by a ball joint and a universal ball joint, which allows this cup holder device to be selectively adapted to different types of storage devices. Considering the stability of the tabletop, the tabletop and the connecting rod can also be connected in other ways, such as threaded connection, bolt connection, snap-fit ​​connection, etc.

[0026] The beneficial effects of this utility model are:

[0027] A continuous elastic driving force is provided by setting an independent elastic element to drive the clamping clips to open. This elastic element is specifically designed to provide clamping force, and its mechanical properties are far superior to those of solutions that rely on the elasticity of the clamping arm material itself. It can provide a stronger and more stable clamping force, and has better fatigue resistance, effectively avoiding the problem of clamping force decay after long-term use, thereby ensuring the reliability of the fixation.

[0028] Furthermore, the clamps of the adaptive tensioning mechanism are driven by elastic elements, and the range of opening angle adjustment is much greater than that of traditional elastic clamps. It can adapt to car cup holders of different diameters and inner wall shapes, and its compatibility covers the cup holder specifications of most car models. Attached Figure Description

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0040] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0041] Example 1

[0042] Reference Figures 1 to 5 This embodiment provides a cup holder device, including a support body 100, a placement device (not shown in the figure) disposed at both ends of the support body 100, and an adaptive tensioning mechanism 300. The placement device includes a ball seat, and a universal ball 110 is connected to the top of the support body 100. The universal ball 110 is rotatably housed within the ball seat, thereby enabling multi-angle adjustment of the placement device relative to the support body 100. The adaptive tensioning mechanism 300 includes a base 310, two pivots 320, four torsion springs 330, and a pair of clamps 340. Each clamp 340 is pivotally connected to the base 310 via a corresponding pivot 320. Specifically, the base 310 includes a first base 315 and a second base 316 adapted to connect to the support body 100, the second base 316 being columnar. The clamps 340 include a first side edge 341 and a second side edge 342 disposed opposite to each other. A first pivot seat 343 protrudes from the first side edge 341. The second base 316 has corresponding protruding second pivot seats 311 on both sides. A pivot 320 passes through the first pivot seat 343 and the second pivot seat 311, thereby achieving a pivotal connection between the clamp 340 and the base 310. The second pivot seat 311 is adapted to axially support the first pivot seat 343. The first pivot seat 343 has a clearance groove 346 for accommodating the coil 331 of the torsion spring 330. The torsion spring 330, as an elastic element, includes a coil 331, a first leg 332, and a second leg 333. The coil 331 is sleeved on the pivot 320. The first leg 332 of the torsion spring 330 abuts against the inner surface of the clamp 340, while the second leg 333 abuts against the inner surface of the second base 316. To secure the positioning of the support legs, the inner surface of the clamp 340 is provided with a first slot 344 for receiving the first support leg 332, and the second base 316 is provided with a second slot 312 for receiving the second support leg 333.

[0043] When the clamp 340 is closed by an external force, the clamp 340 rotates around the pivot 320, which drives the first support leg 332 to move, causing the spring coil 331 to undergo elastic deformation to store elastic potential energy. When the external force is removed, the spring coil 331 releases the elastic potential energy, and drives the clamp 340 to automatically return to the open state through the first support leg 332.

[0044] In this embodiment, the first side edge 341 has an arc-shaped concave surface 347 on the side facing the base 310, and the second pivot seat 311 has an arc-shaped convex surface 314 on the side facing the clamping piece 340, which cooperates with the arc-shaped concave surface 347. The arc-shaped concave surface 347 and the arc-shaped convex surface 314 are adapted to rotate around the same pivot axis 320. A first stop surface 345 is integrally formed on one side of the arc-shaped concave surface 347, and a second stop surface 313 is integrally formed on one side of the arc-shaped convex surface 314. To prevent the clamping piece 340 from opening excessively, when the clamping piece 340 rotates to the preset maximum opening angle, the first stop surface 345 and the second stop surface 313 abut against each other, thus limiting the opening. At the same time, when the second side edges 342 of the two clamping pieces 340 abut against each other, the minimum opening angle is reached.

[0045] In this embodiment, the clip 340 has an arc-shaped cross-section and its outer surface is a circumferential surface to better fit the shape of the inner wall of the cup groove. To increase static friction, the outer surface of the clip 340 may be covered with an elastic friction layer made of silicone (not shown in the figure), and the outer surface of the friction layer may be provided with a textured surface to further enhance the anti-slip effect.

[0046] In this embodiment, the bracket body 100 includes a connecting rod 120 and an adjusting rod 130. One end of the connecting rod 120 is connected to a universal ball joint 110, and the other end is connected to the adjusting rod 130. The other end of the adjusting rod 130 is connected to a first base 315. The connecting rod 120 and the adjusting rod 130 are adapted to rotate relative to each other around a first axis, and the adjusting rod 130 and the first base 315 are adapted to rotate relative to each other around a second axis, with the first axis parallel to the second axis. To achieve locking after angle adjustment, locking mechanisms are respectively provided between the connecting rod 120 and the adjusting rod 130, and between the adjusting rod 130 and the first base 315. The locking mechanism includes a nut (not shown in the figure), a stud 220, and a knob 230. The nut is disposed inside the adjusting rod 130, with one end of the stud 220 extending out of the connecting rod 120 and connected to the knob 230, and the other end extending into the adjusting rod 130 to engage with the nut threadedly. When knob 230 is tightened, stud 220 moves axially forward and backward, causing the end faces of connecting rod 120 and adjusting rod 130 to press against each other, thereby locking the relative angle; loosening knob 230 releases the angle. Another stud 220 has one end protruding from the first base 315 and connected to knob 230, and the other end extending into adjusting rod 130 to engage with the nut threadedly, with the same locking principle. To further enhance the locking effect, the facing end faces of connecting rod 120 and adjusting rod 130 are respectively provided with engaging first toothed rings 240, and the facing end faces of adjusting rod 130 and base 310 are respectively provided with engaging second toothed rings 250.

[0047] Example 2

[0048] Reference Figures 6 to 7 This embodiment provides a cup holder device. The main difference from the previous embodiment is that the two clamping pieces 340 are pivotally connected to the same pivot 320. The spring coil 331 of the torsion spring 330 is sleeved on the same pivot 320, with its first leg 332 abutting against the inner surface of one clamping piece 340, and its second leg 333 directly abutting against the inner surface of the other clamping piece 340. Correspondingly, the inner surface of the clamping piece 340 is provided with a first slot 344 for receiving the first and second legs. In this configuration, the torsion spring 330 acts directly between the two clamping pieces 340, providing an elastic driving force that pulls them apart. Specifically, the base 310 includes a first base 315 and a second base 316 adapted to connect to the support body 100. The clamping piece 340 includes a first side edge 341 and a second side edge 342 disposed opposite to each other. The first side edge 341 has a protruding first pivot seat 343. The first pivot seats 343 on the two clips 340 are staggered in the axial direction to support each other and are defined by three mounting slots from top to bottom. The second base 316 is disposed in the mounting slot at the top, and the other two mounting slots are suitable for accommodating the spring rings 331 of the torsion spring 330.

[0049] When the two clamping plates 340 are brought together by an external force, they respectively drive the first leg 332 and the second leg 333 to rotate, causing the spring coil 331 to twist and deform to store potential energy. After the external force is removed, the torsion spring 330 drives the two clamping plates 340 to automatically and symmetrically open outward.

[0050] In this embodiment, because the two clamping pieces 340 move symmetrically around the same axis and their outer surfaces are precisely constructed, the outer surfaces of the two clamping pieces 340 can together form a complete circumferential surface with the same axis and the same diameter, and its top-view projection forms a continuous arc. This configuration enables the adaptive tensioning mechanism 300 to achieve uniform and linear contact throughout the entire circumference when placed into a circular cup groove with a matching radial dimension, thereby obtaining excellent centering and stability and effectively preventing shaking and rotation.

[0051] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
