[0002] With the improvement of living standards, motor vehicles have become a common means of transportation. With the development of motor vehicles, their multifunctionality has gradually become a focus of attention. The multifunctionality of motor vehicles has expanded the research and development goals beyond simply driving and riding to include additional functions during driving and riding.

[0003] People often drink water when riding in a motor vehicle. In order to stably hold the cup inside, the existing cup holder is often provided with an elastic clamping structure based on elastic material, such as a rubber band, which elastically clamps the cup inside the cup holder.

[0012] In one embodiment, the operating portion is movably mounted on the outside of the cup holder, and a driving lever is fixedly connected thereto. The driving lever corresponds one-to-one with the clamping block and is in transmission cooperation with the clamping block. The first moving direction is the axial direction of the cup holder, and the second moving direction is the circumferential direction of the cup holder.

[0013] In one embodiment, the unlocking portion is arranged on one side of the operating portion in the direction of the cup holder axis, and includes an elastic compression member whose compression direction is in the direction of the cup holder axis; one end of the elastic compression member is fixedly connected to one of the operating portion and the cup holder, and the other end thereof is in relative sliding contact with the other.

[0014] In one embodiment, the operating portion is provided with a flange perpendicular to the radial direction of the cup holder, the flange is provided with a rotation groove extending along the second movement direction, and the flange located on one side of the rotation groove is provided with at least one locking groove extending along the first movement direction, and the locking groove is connected to the rotation groove;

[0015] The limiting portion is a limiting rod fixedly connected to the outer wall of the cup holder and extending radially along the cup holder, the diameter of the limiting rod matches the locking groove, and the limiting rod passes through the flange through the rotation groove or the locking groove;

[0016] When the operating portion is in the unlocking position, the limiting rod is in the rotation groove; when the operating portion is in the non-unlocking position, the limiting rod is in the locking groove.

[0017] In one embodiment, a mounting plate fixedly connected to the cup holder is provided around the cup holder, the mounting plate being perpendicular to the axial direction of the cup holder, the unlocking portion and the limiting portion being fixedly mounted thereon, and the mounting plate being provided with a plurality of movable grooves extending along the circumference of the cup holder, the driving lever passing through the movable grooves being in transmission engagement with the clamping block.

[0018] In one embodiment, a plurality of clamping holes are circumferentially spaced apart on a circumferential side wall of the cup holder. The plurality of clamping blocks are rotatably mounted on the cup holder and correspond one-to-one with the clamping holes. Parts of the clamping blocks extend into the cup holder through the clamping holes, and the rotation axes of the clamping blocks are parallel to the axis of the cup holder so that the specific locations of the clamping blocks extending into the cup holder change during rotation.

[0019] In one embodiment, the clamping block is provided with a plurality of clamping ends in its rotational circumferential direction, and each of the clamping ends extends a different distance in the radial direction of the cup holder when rotated into the cup holder.

After the unlocking part controls the operation part to move to the unlocked position, the limiting part can be used to abut and limit the movement of the operation part in the second direction, thereby positioning the clamping block, that is, positioning the cup clamped by the clamping block. Compared with the prior art that completely relies on the elastic effect of the elastic material to apply clamping force to the cup body, this solution implements clamping limit of the clamping block and the cup by abutting and limiting in another moving direction other than the moving direction of controlling the rotation of the clamping block, and thus the clamping block can be adjusted and positioned without considering the elastic effect of the material, which can effectively solve the problem of the prior art that the elastic material cannot effectively clamp the cup due to aging.

[0039] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0040] With the improvement of living standards, motor vehicles have become a common means of transportation for people. With the development of motor vehicles, the multifunctionality of motor vehicles has gradually become the focus of people's attention. The multifunctionality of motor vehicles has made the research and development goals not only stay on driving and riding, but also expanded the research and development goals to the auxiliary functions of driving and riding. People often drink water when riding in motor vehicles. In order to stably clamp the cups inside, existing cup holders are often provided with an elastic clamping structure based on elastic materials, such as rubber bands, which uses the clamping structure to elastically clamp the cups inside the cup holder. However, elastic materials such as rubber are prone to aging, and their elasticity decreases after aging. The clamping structure may eventually fail to generate sufficient clamping force, resulting in difficulty in stably clamping the cups. Further improvement is needed.

[0041] Based on the above problems, an embodiment of the present application provides a vehicle-mounted cup holder, the key point of the invention is that the unlocking part 3 controls the operation part 2 to switch between the unlocked position and the unlocked position in the first movement direction, and when the operation part 2 is in the unlocked position, it can smoothly move in the second movement direction, and can further drive the clamping block 10 to adjust, so that the clamping block 10 can be used to adapt and clamp the cup placed in the holder. After the unlocking part 3 controls the operation part 2 to move to the unlocked position, the limiting part 4 can be used to abut and limit the movement of the operation part 2 in the second direction, thereby positioning the clamping block 10, that is, positioning the cup body clamped by the clamping block 10. Compared with the prior art that completely relies on the elastic effect of the elastic material to apply clamping force to the cup body, this scheme uses the abutment limit in another movement direction to provide cup clamping limit, and can adjust and position the clamping block 10 without considering the elastic effect of the material, which can effectively solve the problem of the elastic material aging in the prior art that cannot effectively clamp the cup.

[0042] Figure 1 and Figure 2 The present application provides a vehicle-mounted cup holder, which includes a cup holder 1, an operating portion 2, an unlocking portion 3, and a limiting portion 4. A plurality of clamping blocks 10 are arranged circumferentially within the cup holder 1. The clamping blocks 10 are movable and can be adjusted in a direction close to or away from the axis of the cup holder 1.

[0043] Reference Figure 2Specifically, the top of the cup holder 1 is open, and a plurality of clamping holes 12 are circumferentially spaced apart on its circumferential sidewalls. A plurality of clamping blocks 10 are rotatably mounted on the cup holder 1 and correspond one-to-one with the clamping holes 12. Parts of the clamping blocks 10 extend into the interior of the cup holder 1 through the clamping holes 12, and their rotation axes are parallel to the axis of the cup holder 1, so that the specific position of the clamping blocks 10 extending into the interior of the cup holder 1 can be changed during rotation. The clamping blocks 10 are fixedly mounted on the outer wall of the cup holder 1 at clamping block mounting points 13 to achieve rotation on the cup holder 1. Rotational axes 102 (see FIG. 1 ) are integrally provided on both the upper and lower sides of the clamping blocks 10. Figure 6 ), the inclined surface at the end of the rotating shaft 102 mates with the inclined surface on the clamping block mounting point 13, and the clamping block 10 is mounted on the clamping block mounting point 13 by extrusion. In this embodiment, three identical clamping holes 12, clamping blocks 10, and clamping block mounting points 13 are provided at equal angular intervals along the same circumference of the cup holder 1.

[0044] Reference Figure 2 The operating portion 2 is movably arranged on the outside of the cup holder 1 and is transmission-connected to the clamping block 10, and has two movable directions, a first moving direction and a second moving direction, and when it moves in the second moving direction, it will synchronously drive the clamping block 10 to move;

[0045] Specifically, the operating portion 2 is an annular plate-shaped structure that is slidably mounted outside the cup holder 1. It is coaxial with the cup holder 1 and is fixedly connected to a driving lever 20. The driving lever 20 corresponds one-to-one with the clamping block 10 and is in transmission cooperation with the clamping block 10. The operating portion 2 can move in a first direction along the axis of the cup holder 1 and in a second direction along the circumference of the cup holder 1.

[0046] Ultimately, the operating portion 2 can rotate around the axis of the cup holder 1 by driving the lever 20 to rotate the clamping block 10, and the operating portion 2 can switch between the unlocked position and the unlocked position by sliding up and down along the axis of the cup holder 1. With this arrangement, since the first movement direction for switching between the unlocked and unlocked positions is located axially along the cup holder 1, the user can quickly and vertically adjust the position of the operating portion 2 by directly pressing the operating portion 2. This allows the user to quickly and conveniently select whether to unlock the clamping block 10.

[0047] Reference Figure 3-5 , the unlocking portion 3 is transmission-connected to the operating portion 2 and is used to control the operating portion 2 to move to an unlocking position or a non-unlocking position in the first moving direction;

[0048] Specifically, the unlocking portion 3 is disposed on one side of the operating portion 2 in the axial direction of the cup holder 1. It includes an elastic compression member, specifically a spring, whose compression direction is in the axial direction of the cup holder 1. One end of the elastic compression member is fixedly connected to one of the operating portion 2 and the cup holder 1, while the other end is in relative sliding contact with the other. In this embodiment, the bottom end of the elastic compression member is fixedly engaged with the cup holder 1, while the top end is in sliding contact with the bottom surface of the operating portion 2.

[0049] At the same time, refer to Figure 2 The limiting portion 4 is provided on the outer side of the cup holder 1 and is used to abut and limit the operating portion 2 in the second movement direction when it is in the unlocked position. Specifically, the operating portion 2 is provided with a flange 21 that is radially perpendicular to the cup holder 1. The flange 21 is provided with a rotation groove 210 that extends along the second movement direction. The flange 21 located on one side of the rotation groove 210 is provided with at least one locking groove 211 that extends along the first movement direction, and the locking groove 211 is connected to the rotation groove 210. In this embodiment, the limiting portion 4 is specifically a limiting rod 40 that is fixedly connected to the outer wall of the cup holder 1 and extends radially along the cup holder 1. The diameter of the limiting rod 40 matches the locking groove 211. The limiting rod 40 passes through the flange 21 through the rotation groove 210 or the locking groove 211.

[0050] When the elastic compression member drives the operating portion 2 to move in the axial direction of the cup holder 1, i.e., the first movement direction, to the unlocked position, the limiting rod 40 is specifically located in the rotation groove 210. At this time, it can rotate in the second movement direction with the help of the rotation groove 210. When the elastic compression member drives the operating portion 2 to move in the axial direction of the cup holder 1 to the non-unlocked position, the limiting rod 40 will relatively move into the locking groove 211. At this time, it will no longer have space to move in the second movement direction, and the position in the second movement direction will be locked. As a result, the operating portion 2 cannot rotate in the second movement direction, and the clamping block 10 is finally positioned.

[0051] In order to achieve the installation and fixation of the elastic compression member serving as the unlocking portion 3 and the locking portion on the outside of the cup holder 1, an annular mounting plate 11 is provided around the cup holder 1 and fixedly connected to the cup holder 1. The mounting plate 11 is perpendicular to the axial direction of the cup holder 1, and the unlocking portion 3 and the limiting portion 4 are fixedly mounted thereon. The mounting plate 11 is provided with multiple movable grooves 110 extending along the circumference of the cup holder 1. The driving lever 20 passes through the movable grooves 110 and then engages with the clamping block 10 in a transmission manner.

[0052] Specifically, the mounting plate 11 is located between the clamping block 10 and the operating portion 2 in their respective use positions. A spring column 112 for securely connecting an elastic compression member is provided on the side of the mounting plate 11 close to the operating portion 2. The end of the elastic compression member is fixedly sleeved on the spring column 112. Furthermore, a mounting block 111 for mounting a limiting rod 40 is provided on this side of the mounting plate 111. The limiting rod 40 is specifically a limiting screw that is threadedly engaged with the mounting block 111. Both the mounting block 111 and the spring column 112 are located on the inner side of the flange 21 of the operating portion 2. The elastic compression member on the spring column 112 constantly tends to push the operating portion 2 upward away from the mounting plate 11 due to its elastic force. This allows the limiting rod 40 to tend to move downward relative to the operating portion 2 when no pressure is applied to the operating portion 2. When the limiting rod 40 aligns with the locking groove 211 circumferentially of the cup holder 1, it is elastically moved into the locking groove 211 and into the unlocked position, thereby positioning the clamping block 10. The clamping block 10 remains fixed and can position a cup placed therein. When the operating portion 2 is subjected to external downward pressure, the elastic compression member compresses, causing the limiting rod 40 to move upward relative to the flange 21 until it enters the rotation groove 210, i.e., the unlocked position. At this point, the operating portion 2 has room to rotate in the second direction, and the clamping block 10 is now unlocked.

[0053] Further, in some embodiments, referring to Figure 6 The clamping block 10 is provided with multiple clamping ends 100 along its rotational circumference. Each clamping end 100 extends a different distance radially in the cup holder 1 when rotated into the cup holder 1. Consequently, different clamping ends 100 of the clamping block 10 occupy different distances of space within the cup holder 1 when rotated into the cup holder 1. Furthermore, in this embodiment, to ensure that each clamping end 100 of the clamping block 10 can be locked within the cup holder 1, multiple locking grooves 211 are provided on one side of the rotation groove 210. For example, if the clamping block 10 has three clamping ends 100, each of the three clamping ends 100 has a corresponding locking groove 211 on the rotation groove 210. When the limiting rod 40 aligns with each locking groove 211, the corresponding clamping ends 100 on the multiple clamping blocks 10 will rotate synchronously into the cup holder 1, forming a clamping area for cups with diameters a, b, and c, thereby accommodating cups of varying diameters for placement and positioning in the cup holder.

[0054] To achieve transmission coordination between the driving lever 20 and the clamping block 10, the driving lever 20 extends axially along the cup holder 1. The clamping block 10 is provided with a driving slot 101 for the driving lever 20 to pass through. The driving slot 101 is located on one side of the clamping block 10's rotation axis and extends in the direction of the rotation axis. Consequently, as the driving lever 20 rotates with the operating unit 2, it pushes the clamping block 10 to rotate, while also moving away from or closer to the clamping block 10's rotation axis within the driving slot 101.

[0055] Reference Figure 2 , further, in some embodiments, further comprising:

[0056] The coaster 5 is positioned within the cup holder 1 and is provided with a protrusion corresponding to the clamping block 10. At least the protrusion is made of an elastically deformable material to adapt to the changes in the clamping block 10 within the cup holder 1 after rotation. Specifically, the coaster 5 is wrapped around the inner wall of the cup holder 1. The protrusions are integrally formed on the coaster 5 and correspond one-to-one with the clamping block 10. In this embodiment, the coaster 5 is entirely made of a soft rubber material, providing a cushioning effect between the cup and the clamping block 10. Furthermore, the protrusions are corrugated to accommodate deformation caused by the rotation of the clamping block 10.

[0057] Finally, the vehicle-mounted cup holder provided in the present application allows the user to press the operating part 2 in the axial direction of the cup holder 1, that is, the first moving direction, so that it overcomes the elastic force of the elastic compression member serving as the unlocking part 3 and moves downward. At the same time, the limiting rod 40 in the locking groove 211 will move relatively upward into the rotating groove 210, thereby realizing the movement of the operating part 2 from the non-unlocked position to the unlocked position. At this time, the operating part 2 can rotate in the circumferential direction of the cup holder 1, that is, the second moving direction, and while rotating, it will synchronously drive the clamping block 10 below to rotate with the help of the driving lever 20. When the operating lever moves along the rotation slot 210 to align with the next locking slot 211, the next clamping end 100 on the clamping block 10 rotates into the cup holder 1 accordingly, forming a coaxial clamping area with the cup holder 1 together with the other clamping ends 100 of the other clamping blocks 10. At this point, when the user releases the downward pressure on the operating portion 2 in the axial direction of the cup holder 1, the operating portion 2 moves upward under the return force of the unlocking portion 3, simultaneously driving the limiting rod 40 downward and relatively into the locking slot 211 below. At this point, the operating portion 2 is locked in the second movement direction, thus locking the clamping block 10 and enabling the cup placed in the clamping area to be positioned. To unlock the clamping block 10 or adjust the radius of the clamping area formed by the clamping block 10, simply repeat the above process: press the operating portion 2 downward and then rotate it circumferentially until the clamping block 10 is unlocked or the limiting rod 40 is moved to the locking slot 211 at a different position. Ultimately, users can use the car cup holder provided by the application quickly and conveniently, and the car cup holder avoids relying on the elastic force of the elastic material when clamping and positioning the cup, thereby ensuring the service life of the car cup holder.
