Description

Technical Field

[0001] The present invention relates to the technical field of vehicle interior decoration, and in particular to a cup holder, an armrest box assembly and a vehicle. Background Art

[0002] Cup holders are common vehicle accessories, typically found in the armrest. To enhance the aesthetics and cleanliness of the vehicle interior, some vehicles feature retractable cup holders. When not in use, they collapse, creating a smooth surface on the armrest that seamlessly blends in with the overall vehicle design. When needed, they unfold to create a storage cavity for cups.

[0003] In the prior art, a retractable cup holder includes at least an outer tube and an inner tube. The outer tube is fixedly connected to the armrest box, a slide groove is provided on the surface of the outer tube facing the accommodating cavity, and a slider is provided on the contact surface of the inner tube with the outer tube. The slider and the slide groove slide together to realize the sliding of the inner tube relative to the outer tube, thereby shrinking, folding or unfolding the cup holder.

[0004] However, when the cup holder is unfolded, the chute on the inner side of the outer tube is exposed in the accommodating cavity. When a user places a cup into the accommodating cavity, the cup may collide with the cup, causing wear of the chute or the cup. Summary of the Invention

[0005] One of the purposes of the present invention is to provide a cup holder to solve the problem in the prior art that when a user places a cup into the cup holder's accommodating cavity, the slide groove on the inner side of the outer tube may collide with the cup, causing wear of the slide groove or the cup; the second purpose of the present invention is to provide an armrest box assembly; the third purpose of the present invention is to provide a vehicle.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0007] In a first aspect, the present application provides a cup holder, comprising: an outer cylinder, the outer cylinder having a accommodating cavity open at both ends along the axial direction; a first inner cylinder, comprising a first cylinder body and a first sliding structure, the first cylinder body being slidably arranged on the inner side of the accommodating cavity, the first cylinder body having a first inner cavity open at the top, the first sliding structure being located on the outer side of the outer cylinder and slidingly cooperating with the outer cylinder; a second inner cylinder, being in the shape of a cylinder with a closed top, the second inner cylinder being slidably arranged in the first inner cavity.

[0008] According to the above technical means, the first inner tube slides with the outer tube, the second inner tube slides with the first inner tube, the top of the second inner tube is closed, and when the cup holder is not in use, the cup holder is folded, the top of the second inner tube and the circumference of the outer tube are on the same plane, and the cup holder as a whole presents a smooth plane. When the cup holder needs to be used, the cup holder is unfolded, the first inner tube is controlled to slide relative to the outer tube, and the second inner tube slides relative to the outer tube to provide a storage space for the cups, and the top of the second inner tube is used to place the cups. Compared with the prior art, the first tube body of the first inner tube of the present application is slidably connected to the outer tube by a first sliding structure, and the first sliding structure is located on the outside of the outer tube, that is, on the side of the outer tube facing away from the storage chamber. Therefore, when the cup holder is unfolded, the inner wall of the storage chamber is a smooth surface, which helps to reduce the possibility of the cups colliding with the inner wall or other structures of the storage chamber when they are placed in the storage chamber, thereby avoiding wear of the cups. At the same time, the outer tube of the present application can be fixed to the armrest box assembly, and there is an installation space in the armrest box assembly. The cup holder is fixed in the installation space, and the first sliding structure is arranged on the outside of the outer tube. It can be ensured that the first sliding structure is always located in the installation space, and the cup holder will not be exposed to the external environment whether it is folded or unfolded, which is beneficial to reduce the wear of the first sliding structure and the outer tube, improve the reliability of the cup holder, and extend the service life of the cup holder.

[0009] Furthermore, the cup holder is suitable for switching between a first state, a second state, and a third state; wherein, in the first state, the top ends of the outer tube, the first inner tube, and the second inner tube are flush; in the second state, the top ends of the first inner tube and the second inner tube are flush and mutually recessed in the top end of the outer tube; in the third state, the top end of the first inner tube is recessed in the top end of the outer tube, and the top end of the second inner tube is recessed in the top end of the first inner tube.

[0010] According to the above technical means, when the cup holder is not needed, adjusting the cup holder to the first position allows the cup holder to remain flush with the surface of the armrest box assembly, giving the armrest box assembly a flat and smooth outer surface, which is beneficial to improving the aesthetics of the vehicle interior. It also prevents foreign matter such as dust from entering the storage chamber, which is beneficial to ensuring the cleanliness of the cup holder. When the cup holder is needed to hold cups, the cup holder can be adjusted to the second and third positions according to the height of the cups. For example, when the cup is relatively short, the cup holder can be adjusted to the second position to ensure that the cup is at least partially above the top of the outer tube, so that the user can easily remove the cup from the cup holder. When the cup is relatively tall, the cup holder can be adjusted to the third position to improve the stability of the cup placement and prevent the cup from tipping over during vehicle driving.

[0011] Furthermore, the outer wall of the outer cylinder is provided with a guide structure extending along its own axial direction, and the first sliding structure is guided and matched with the guide structure.

[0012] According to the above technical means, the guiding cooperation between the first sliding structure and the guide structure enables the first inner tube to always maintain a stable, smooth and precise motion trajectory during the sliding process, which is conducive to ensuring the stability of the cup holder when expanding and contracting, avoiding shaking or jamming, thereby enhancing the reliability and durability of the cup holder and improving the user experience of the cup holder.

[0013] Furthermore, the guide structure is formed as a guide groove, and the first sliding structure is formed as a sliding arm.

[0014] The above technical means are conducive to improving the accuracy of the movement trajectory and the smoothness of the sliding of the cup holder during expansion and contraction, avoiding the shaking or deviation of the first inner tube during movement, and making the expansion and contraction of the cup holder more stable.

[0015] Furthermore, a first flange is provided at the top end of the outer wall of the outer cylinder, and a second flange is formed at the bottom end of the outer wall of the outer cylinder. The guide groove extends to the first flange and the second flange respectively. A through hole connected to the guide groove is provided on the second flange, and the sliding arm is passed through the through hole; wherein, in the first state, the top end of the first sliding structure is limitedly engaged with the first flange, and in the second state, the first sliding structure is limitedly engaged with the second flange.

[0016] With this technical approach, the sliding arm, passing through the through-hole, precisely fits into the guide groove and achieves a sliding engagement with it. This helps enhance the overall structural stability of the outer tube, improves the precision of the sliding engagement between the sliding arm and the guide groove, and thus improves the stability of the first inner tube as it slides relative to the outer tube. Furthermore, the first and second flanges act as a restraining force on the first inner tube, improving the reliability of the cup holder.

[0017] Furthermore, a limiting protrusion protruding outwardly in the radial direction of the outer cylinder is provided at one end of the first sliding structure away from the first cylinder body. In the second state, the limiting protrusion abuts against the second flange.

[0018] According to the above technical means, it is beneficial to ensure the smoothness of the sliding cooperation between the first sliding structure and the guide structure while ensuring the effectiveness of the limiting cooperation between the first sliding structure and the second flange, thereby preventing the first inner tube from separating from the outer tube, which is beneficial to ensuring the stability and reliability of the cup holder.

[0019] Furthermore, a first hook is provided on the outer wall of the outer tube, and a second hook is provided on the outer wall of the first inner tube. The cup holder also includes: a first elastic return member, one end of the first elastic return member is connected to the first hook, and the other end is connected to the second hook. The first elastic return member has a pre-action force on the first inner tube to make the first inner tube tend to the first state.

[0020] According to the above technical means, in the first state, the first elastic return member can ensure that the top of the first inner tube always remains flush with the outer tube, preventing displacement due to external impact or vibration, which helps to ensure the stability of the cup holder in the first state. When the cup holder is needed, when the first inner tube is pushed downward along the axial direction of the outer tube, the first elastic return member can provide a certain amount of damping, which helps to improve the sliding stability of the first inner tube and enhance the user experience of the cup holder. When the cup holder is used and needs to be retracted and folded back to the first state, the first elastic return member drives the first inner tube to rise along the axial direction of the outer tube, thereby achieving automatic retraction of the cup holder, which helps to further improve the convenience of using the cup holder.

[0021] Furthermore, it also includes: a first locking assembly, including: a locking pin, which is slidably provided on the outer wall of the outer cylinder along the circumference of the outer cylinder, and in the first state, the locking pin and the moving path of the first sliding structure are staggered, and in the second state and the third state, the locking pin interferes with the first sliding structure; a trigger member, which is provided on the first flange and is movable along the axial direction of the outer cylinder; a transmission member, which is provided on the outer wall of the outer cylinder, and is respectively cooperated with the locking pin and the trigger member for transmission, and the transmission member is used to convert the axial movement of the trigger member along the outer cylinder into the circumferential movement of the locking pin along the outer cylinder.

[0022] According to the above technical means, in the second and third states, the first locking assembly can precisely lock the relative position of the first inner tube and the outer tube, ensuring that the cup holder remains stable during use and prevents it from loosening or shaking due to vehicle bumps or external forces. This enhances the reliability of the cup holder in supporting cups and prevents cups from tipping over and being damaged due to instability. It also reduces mechanical wear between the outer tube and the first inner tube caused by frequent shaking, thereby improving the durability of the cup holder and extending its service life.

[0023] Furthermore, a pivot shaft is provided on the peripheral wall of the outer cylinder, and the transmission member includes: a rotating ring rotatably mounted on the pivot shaft; a first transmission arm abutting against the trigger member along the axial direction of the outer cylinder; and a second transmission arm abutting against the locking pin along the circumferential direction of the outer cylinder.

[0024] According to the above technical means, the trigger member is pressed along the axial direction of the outer tube, and the trigger member drives the end of the first transmission arm to move downward along the axial direction of the outer tube. The first transmission arm drives the rotating ring to rotate, and the rotating ring drives the second rotating arm to rotate. The end of the second transmission arm drives the locking pin to slide along the axial direction of the outer tube, so that the locking pin and the first sliding structure are offset, thereby releasing the lock between the first inner tube and the outer tube.

[0025] Furthermore, the side wall of the second inner cylinder is provided with a slide groove extending along the axial direction of the outer cylinder, and the slide groove penetrates the side wall of the second inner cylinder along the radial direction of the outer cylinder. The first inner cylinder also includes a second sliding structure, one end of the second sliding structure is connected to the first cylinder body, and the other end extends to the inner side of the second inner cylinder through the slide groove, and the second sliding structure slides in cooperation with the slide groove.

[0026] According to the above technical means, the second inner cylinder and the first inner cylinder are slidably matched via the slide groove and the second sliding structure. The slide groove extends along the axial direction of the outer cylinder. The slide groove plays a certain guiding role, ensuring that the second inner cylinder slides relative to the first inner cylinder in the correct direction and path, which is conducive to ensuring the stability and reliability of the relative sliding of the second inner cylinder and the first inner cylinder.

[0027] Furthermore, the slide groove is provided with a stop structure on at least one side along the circumference of the outer cylinder, and the stop structure is located at the bottom end of the second inner cylinder; the second sliding structure is provided with a stop matching structure, and the stop matching structure and the stop structure are arranged opposite to each other along the axial direction of the outer cylinder. In the first state and the second state, the stop matching structure abuts against the stop structure to limit the second inner cylinder.

[0028] According to the above technical means, in order to prevent the second inner tube from being higher than the first inner tube under the action of the second elastic return member, a stop matching structure and a stop structure need to be provided, thereby ensuring that the first inner tube and the second inner tube remain flush in the first state and the second state, which is beneficial to improving the aesthetics of the cup holder and at the same time improving the stability of the cup holder in the first state and the second state.

[0029] Furthermore, the first inner tube also includes a support plate, which is connected to the first tube body and is opposite to the top wall of the second inner tube along the axial direction of the outer tube; the cup holder also includes: a second elastic return member, one end of the second elastic return member abuts against the support plate, and the other end abuts against the top wall of the second inner tube, and the second elastic return member has a pre-action force on the second inner tube to make the second inner tube tend to the first state.

[0030] According to the above technical approach, in both the first and second states, the second elastic return member provides a certain degree of support for the second inner tube, preventing the second inner tube from sliding downward along the axial direction of the first inner tube under the pressure of the cup when placed in the cup holder, thereby ensuring the stability of the first and second states. Furthermore, the second elastic return member also provides a certain degree of damping when the cup holder switches from the second state to the third state, which helps to improve the stability of the second inner tube sliding relative to the first inner tube. When the external force acting on the second inner tube disappears, the second inner tube automatically returns to its original position under the drive of the second elastic return member, further improving the convenience of using the cup holder.

[0031] Furthermore, the support plate is provided with a guide column extending along the axial direction of the outer cylinder, the top wall of the second inner cylinder is provided with a sleeve extending along the axial direction of the outer cylinder, one end of the second elastic return member is sleeved on the outside of the guide column, and the other end is inserted into the inside of the sleeve.

[0032] According to the above technical means, the second elastic return member is sleeved on the guide column, which is conducive to ensuring that the position of the second elastic return member does not shift, ensuring the stability of the second elastic return member, and ensuring that the force applied by the second elastic return member to the second inner tube is along the axial direction of the outer tube, so that the second inner tube can be accurately reset to its original position, further improving the precision of the cup holder structure.

[0033] Furthermore, the side wall of the first inner tube is provided with a first locking hole that penetrates radially along the outer tube, and the inner wall of the second inner tube is provided with a second locking hole that penetrates radially along the outer tube, and the cup holder further includes: a second locking member, which is movably arranged on the inner side of the second inner tube; wherein, in the third state, the first locking hole and the second locking hole are opposite to each other, and the second locking member passes through the second locking hole and the first locking hole in sequence under the push of the second sliding structure, so that the second inner tube remains fixed in position relative to the first inner tube; in the first state, the second locking member exits the first locking hole under the push of the outer tube, and the second inner tube is movable relative to the first inner tube.

[0034] According to the above technical means, the second locking member is used to lock the relative position between the first inner cylinder and the second inner cylinder in the third state, thereby preventing the second inner cylinder from sliding relative to the first inner cylinder due to bumps and vibrations during vehicle driving, which is beneficial to improving the stability of the cup holder in the third state. At the same time, it can also avoid mechanical wear between the second inner cylinder and the first inner cylinder caused by frequent shaking, which is beneficial to further improve the durability of the cup holder and extend the service life of the cup holder.

[0035] Furthermore, the second locking member includes: a locking trigger section, an inserting section and an unlocking trigger section connected in sequence, the locking trigger section is pivotally connected to the inner wall of the second inner cylinder, and any two adjacent ones of the locking trigger section, the inserting section and the unlocking trigger section have an included angle. In the third state, the locking trigger section is parallel to the axial direction of the outer cylinder, the inserting section extends along the radial direction of the outer cylinder, and the unlocking trigger section extends obliquely to a side away from the top wall of the second inner cylinder relative to the inserting section. The locking trigger section is suitable for rotating relative to the second inner cylinder under the resistance of the second sliding structure, so that the inserting section passes through the second lock hole and the first lock hole in sequence, and the unlocking trigger section is suitable for driving the trigger section to exit the first lock hole under the resistance of the outer cylinder.

[0036] According to the above technical means, when the cup holder switches from the second state to the third state, the first inner tube and the second inner tube are locked by the locking trigger section. When switching from the third state to the first state, unlocking is achieved by the unlocking trigger section. Locking or unlocking can be achieved synchronously during the switching process without the need for additional operations, which is conducive to further improving the convenience of using the cup holder and enhancing the user experience of the cup holder.

[0037] In a second aspect, the present application provides an armrest box assembly, comprising the cup holder described in any one of the first aspects.

[0038] According to the above technical means, by using the above cup holder, when there is no need to place cups, the surface of the armrest box assembly is flat and smooth. When cups need to be placed, they only need to be placed on the top of the second inner tube and pressed down. This can not only meet the user's needs for placing cups, but also ensure the aesthetics of the armrest box assembly.

[0039] In a third aspect, the present application provides a vehicle comprising: the armrest box assembly of the second aspect, or the cup holder described in any one of the first aspect.

[0040] According to the above technical means, by using the above-mentioned armrest box assembly or cup holder, the overall aesthetics of the vehicle interior is improved. At the same time, different types of cups can be placed according to the different usage needs of users, which is conducive to improving the driving experience of the vehicle.

[0041] Beneficial effects of the present invention:

[0042] (1) The cup holder of the present invention can be flexibly folded or unfolded, ensuring the aesthetics of the vehicle interior while meeting the different usage needs of users;

[0043] (2) After the cup holder of the present invention is unfolded, the inner wall of the accommodating cavity remains smooth, which helps to prevent the cup from colliding with the inner wall of the accommodating cavity or other structures, thereby reducing the probability of the cup being worn;

[0062] The following describes the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art will readily appreciate the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the various details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0063] In the prior art, a retractable cup holder consists of at least an outer tube and an inner tube. The outer tube is fixedly connected to the armrest box, and a slide groove is provided on the side of the outer tube facing the receiving cavity. The inner tube is provided with a slider on the contact surface with the outer tube. The slider and the slide groove slide together to slide the inner tube relative to the outer tube, thereby collapsing or expanding the cup holder. However, when the cup holder is expanded, the slide groove inside the outer tube is exposed to the receiving cavity. When a user places a cup into the receiving cavity, the cup may collide with the cup, causing wear and tear on the slide groove or the cup.

[0064] To address the above technical issues, embodiments of the present application provide a cup holder, an armrest box assembly, and a vehicle. The cup holder includes an outer tube, a first inner tube, and a second inner tube. The first inner tube slides with the outer tube, and the second inner tube slides with the first inner tube. The top of the second inner tube is closed. When the cup holder is not in use, the cup holder is folded, and the top of the second inner tube is flush with the circumference of the outer tube, resulting in a smooth overall surface. When the cup holder is needed, the cup holder is unfolded, and the first inner tube and the second inner tube slide relative to the outer tube to provide a storage space for cups. The top of the second inner tube is used to place the cups. Compared to the prior art, the first tube body of the first inner tube of the present application is slidably connected to the outer tube via a first sliding structure. The first sliding structure is located on the outer side of the outer tube, that is, on the side of the outer tube facing away from the storage chamber. Therefore, when the cup holder is unfolded, the inner wall of the storage chamber is smooth, which helps reduce the possibility of cups colliding with the inner wall or other structures of the storage chamber when placed in the storage chamber, thereby preventing wear on the cups. At the same time, the outer tube of the present application can be fixed to the armrest box assembly, and there is an installation space in the armrest box assembly. The cup holder is fixed in the installation space, and the first sliding structure is arranged on the outside of the outer tube. It can be ensured that the first sliding structure is always located in the installation space, and the cup holder will not be exposed to the external environment whether it is folded or unfolded, which is beneficial to reduce the wear of the first sliding structure and the outer tube, improve the reliability of the cup holder, and extend the service life of the cup holder.

[0065] The following specific embodiments are used to describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The following embodiments of the present application are described in conjunction with the accompanying drawings:

[0066] It should be noted that the cup holder provided in the embodiment of the present application can be applied to various armrest box assemblies or vehicles.

[0067] See also Figures 1 to 3 As shown, an embodiment of the present application provides a cup holder, comprising: an outer cylinder 100, a first inner cylinder 200, and a second inner cylinder 300. The outer cylinder 100 has a receiving cavity open at both ends along the axial direction; the first inner cylinder 200 includes a first cylinder body 210 and a first sliding structure 220. The first cylinder body 210 is slidably arranged inside the receiving cavity. The first cylinder body 210 has a first inner cavity open at the top. The first sliding structure 220 is located on the outside of the outer cylinder 100 and slides with the outer cylinder 100; the second inner cylinder 300 is in the shape of a cylinder with a closed top, and the second inner cylinder 300 is slidably arranged in the first inner cavity.

[0068] In an embodiment of the present application, a cup holder can be mounted on a vehicle's armrest assembly. The armrest assembly defines an installation space within which the cup holder is mounted. The outer cylinder 100 is fixedly connected to the armrest assembly. When the cup holder is not in use, the cup holder folds and contracts, with the second inner cylinder 300 retracted within the first inner cavity and the first inner cylinder 200 retracted within the accommodating cavity. Thus, the top of the second inner cylinder 300 is flush with the upper edge of the outer cylinder 100, resulting in a smooth and flat outer surface for the armrest assembly, which improves the aesthetics of the vehicle interior. When the cup holder is needed to hold cups, the first and second cylinders are simply slid downwardly along the axis of the outer cylinder 100. The cup holder then unfolds, exposing the accommodating cavity and the first inner cavity, providing ample space for the cup holder to meet user needs.

[0069] It should be noted that in the embodiments of the present application, the inner side and outer side of the outer cylinder 100 refer to the side of the outer cylinder 100 facing the accommodating cavity and the side facing away from the accommodating cavity, respectively. In the prior art, a sliding structure, such as a slide rail or a slide groove 310, is provided between the first cylinder body 210 and the outer cylinder 100. When the cup holder is deployed, the sliding structure is located within the accommodating cavity, resulting in an uneven inner wall of the accommodating cavity. This not only affects the aesthetics of the cup holder, but also easily causes the cup to collide with the sliding structure when the cup is placed in the cup holder, causing wear on the cup or the sliding structure and affecting the reliability of the cup holder. Furthermore, since the sliding structure is exposed to the external environment when the cup holder is deployed, foreign matter may enter the sliding structure, affecting the smoothness of the relative sliding between the first cylinder body and the outer cylinder 100.

[0070] Therefore, in the embodiment of the present application, the first sliding structure 220 is disposed on the outside of the outer cylinder 100. The first cylinder body 210 slides with the outer cylinder 100 via the first sliding structure 220. In this way, the accommodating cavity and the first sliding structure 220 are located on the inner and outer sides of the outer cylinder 100, respectively. When the cup holder is deployed, the inner wall of the accommodating cavity remains smooth, which facilitates the placement of cups and prevents collision with the inner wall of the accommodating cavity, thereby protecting the cups from damage and improving the reliability of the cup holder. Furthermore, the first sliding structure 220 is always located on the outside of the outer cylinder 100, so it is never exposed to the external environment. This prevents external debris from entering the first sliding structure 220 and affecting the smooth sliding of the first inner cylinder 200. This also helps reduce wear on the first sliding structure 220, thereby extending the service life of the cup holder and enhancing its reliability.

[0071] It should be noted that the outer cylinder 100, the first inner cylinder 200 and the second inner cylinder 300 can be cylinders, prisms, etc. The embodiment of the present application does not limit their specific shapes. As long as the shapes of the outer cylinder 100, the first inner cylinder 200 and the second inner cylinder 300 correspond to each other and can be slidably matched, they can be reasonably selected according to the type of cups to be contained and the shape of the installation space.

[0072] In some possible implementations, see Figures 1 to 3 As shown, the cup holder of the embodiment of the present application is suitable for switching between a first state, a second state and a third state; wherein, in the first state, the top ends of the outer cylinder 100, the first inner cylinder 200 and the second inner cylinder 300 are flush; in the second state, the top ends of the first inner cylinder 200 and the second inner cylinder 300 are flush and both recessed within the top end of the outer cylinder 100; in the third state, the top end of the first inner cylinder 200 is recessed within the top end of the outer cylinder 100, and the top end of the second inner cylinder 300 is recessed within the top end of the first inner cylinder 200.

[0073] In practice, when the cup holder is not needed, the cup holder is adjusted to the first position. At this point, the tops of the outer cylinder 100, the first inner cylinder 200, and the second inner cylinder 300 are flush, allowing the cup holder to remain flush with the surface of the armrest box assembly, giving the armrest box assembly a smooth and even outer surface, thereby improving the aesthetics of the vehicle interior and preventing foreign matter such as dust from entering the storage chamber, thereby ensuring the cleanliness of the cup holder. When the cup holder is needed to hold cups, the cup holder can be adjusted to the second and third positions depending on the height of the cups. For example, if the cups are relatively short, the cup holder can be adjusted to the second position to ensure that at least a portion of the cups are above the top of the outer cylinder 100, allowing the user to easily remove the cups from the cup holder. If the cups are relatively tall, the cup holder can be adjusted to the third position to improve the stability of the cups and prevent them from tipping over during vehicle operation.

[0074] Therefore, the cup holder of the embodiment of the present application can switch between the first state, the second state and the third state according to the different usage needs of the user. It is highly flexible and can enrich the models of applicable cups of the cup holder while ensuring the aesthetics of the vehicle, which is conducive to improving the user's usability experience.

[0075] In some possible implementations, see Figures 1 to 3 As shown, the outer wall of the outer cylinder 100 of the embodiment of the present application is provided with a guide structure 110 extending along its own axial direction, and the first sliding structure 220 is guided and matched with the guide structure 110.

[0076] In some embodiments, the guiding cooperation between the first sliding structure 220 and the guide structure 110 enables the first inner cylinder 200 to always maintain a stable, smooth and precise motion trajectory during the sliding process, which is conducive to ensuring the stability of the cup holder when expanding and contracting, avoiding shaking or jamming, thereby enhancing the reliability and durability of the cup holder and improving the user experience of the cup holder.

[0077] For example, the guide structure 110 is formed as a guide groove, and the first sliding structure 220 is formed as a sliding arm. The sliding arm precisely fits within the guide groove and slides smoothly along the guide groove's trajectory. This helps improve the accuracy of the cup holder's motion trajectory and smoothness of movement during expansion and contraction, preventing potential shaking or deviation of the first inner tube 200 during movement, thereby providing more stable expansion and contraction of the cup holder. Furthermore, the sliding arm can be coated with an elastic material to create a certain amount of interference between the sliding arm and the guide groove, thereby providing damping during the sliding of the first inner tube 200 relative to the outer tube 100. This further improves the stability of the sliding of the first inner tube 200 relative to the outer tube 100 and enhances the user experience of the cup holder.

[0078] Of course, the guide structure 110 and the first sliding structure 220 can also be set as different structures such as slide rails and sliders. The embodiment of the present application does not limit this, as long as the guide cooperation can be achieved.

[0079] In some possible implementations, see Figures 1 to 3 As shown, a first flange 120 is provided at the top end of the outer wall of the outer cylinder 100 of the embodiment of the present application, and a second flange 130 is formed at the bottom end of the outer wall of the outer cylinder 100. Both ends of the guide structure 110 extend to the first flange 120 and the second flange 130 respectively. A through hole connected to the guide groove is provided on the second flange 130, and the sliding arm is passed through the through hole; wherein, in the first state, the top end of the first sliding structure 220 is limitedly matched with the first flange 120, and in the second state, the first sliding structure 220 is limitedly matched with the second flange 130.

[0080] As can be appreciated, the sliding arm, passing through the through-hole, precisely fits into the guide groove and slides therewith, thereby enhancing the overall structural stability of the outer cylinder 100 and improving the precision of the sliding fit between the sliding arm and the guide groove, thereby improving the stability of the first inner cylinder 200 during its sliding relative to the outer cylinder 100. Furthermore, the first flange 120 and the second flange 130 serve to restrain the first inner cylinder 200. When the cup holder is retracted, the first inner cylinder 200 slides upward along the axial direction of the outer cylinder 100 until the first sliding structure 220 abuts the first flange 120, preventing further sliding of the first inner cylinder 200 and ensuring that the top end of the first inner cylinder 200 is flush with the top end of the outer cylinder 100 in the first state. When the cup holder is deployed, the first inner cylinder 200 slides downward along the axial direction of the outer cylinder 100 until the first sliding structure 220 abuts the second flange 130, preventing the first inner cylinder 200 from separating from the outer cylinder 100 and improving the reliability of the cup holder.

[0081] In some possible implementations, see Figures 1 to 3As shown, the first sliding structure 220 of the embodiment of the present application is provided with a limiting protrusion 221 protruding radially outward from the outer cylinder 100 at one end away from the first cylinder body 210 . In the second state, the limiting protrusion 221 abuts against the second flange 130 .

[0082] In a specific implementation, a limiting protrusion 221 is provided on the first sliding structure 220, which is beneficial to ensuring the smoothness of the sliding fit between the first sliding structure 220 and the guide structure 110 while ensuring the effectiveness of the limiting fit between the first sliding structure 220 and the second flange 130, thereby preventing the first inner cylinder 200 from separating from the outer cylinder 100, which is beneficial to ensuring the stability and reliability of the cup holder.

[0083] Correspondingly, a limiting cooperation structure 131 corresponding to the limiting protrusion 221 can be provided on the side of the second flange 130 facing the first flange 120, and the limiting protrusion 221 abuts against the limiting cooperation to realize the limiting cooperation. Of course, the specific structure of the second flange 130 is not limited in the embodiment of this application, and can be reasonably designed according to actual conditions.

[0084] In some possible implementations, see Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, the outer wall of the outer cylinder 100 of the embodiment of the present application is further provided with a first hook 140, the outer wall of the first inner cylinder 200 is provided with a second hook 230, and the cup holder further includes a first elastic return member 400, one end of the first elastic return member 400 is connected to the first hook 140, and the other end is connected to the second hook 230, and the first elastic return member 400 has a pre-force on the first inner cylinder 200 to make the first inner cylinder 200 tend to the first state.

[0085] In a specific implementation, the first elastic return member 400 can be a spring or the like, and this embodiment of the present application does not impose any restrictions on this. When the cup holder is not needed, the cup holder is in the first state, and the first elastic return member 400 can ensure that the top of the first inner cylinder 200 always remains flush with the outer cylinder 100, avoiding displacement due to external impact or vibration, which is beneficial to ensuring the stability of the cup holder in the first state. When the cup holder is needed, when the first inner cylinder 200 is pushed downward along the axial direction of the outer cylinder 100, the first elastic return member 400 can provide a certain amount of damping, which is beneficial to improving the sliding stability of the first inner cylinder 200 and improving the user experience of the cup holder. When the cup holder is used and needs to be retracted and folded back to the first state, the first elastic return member 400 drives the first inner cylinder 200 to rise along the axial direction of the outer cylinder 100, thereby realizing automatic retraction of the cup holder, which is beneficial to further improving the convenience of using the cup holder.

[0086] In some possible implementations, see Figures 1 to 5As shown, the embodiment of the present application also includes: a first locking assembly 500, including: a locking pin 510, a trigger member 520 and a transmission member 530, the locking pin 510 is slidably provided on the outer wall of the outer cylinder 100 along the circumference of the outer cylinder 100, in the first state, the locking pin 510 is staggered with the movement path of the first sliding structure 220, in the second state and the third state, the locking pin 510 interferes with the first sliding structure 220; the trigger member 520 is provided on the first flange 120, and the trigger member 520 is movable along the axial direction of the outer cylinder 100; the transmission member 530 is provided on the outer wall of the outer cylinder 100, and the transmission member 530 is respectively engaged with the locking pin 510 and the trigger member 520, and the transmission member 530 is used to convert the axial movement of the trigger member 520 along the outer cylinder 100 into the circumferential movement of the locking pin 510 along the outer cylinder 100.

[0087] It will be appreciated that in the second and third positions, the first locking assembly 500 precisely locks the relative position of the first inner cylinder 200 and the outer cylinder 100, ensuring the stability of the cup holder during use and preventing it from loosening or shaking due to vehicle bumps or external forces. This enhances the reliability of the cup holder in supporting cups and prevents cups from tipping over and being damaged due to instability. It also reduces mechanical wear between the outer cylinder 100 and the first inner cylinder 200 caused by frequent shaking, thereby improving the durability of the cup holder and extending its service life.

[0088] Specifically, in the first state, the locking pin 510 is offset from the first sliding structure 220, preventing it from interfering with the sliding of the first inner cylinder 200 and ensuring smooth sliding of the first inner cylinder 200 relative to the outer cylinder 100. In the second and third states, the locking pin 510 interferes with the first sliding structure 220, preventing the first inner cylinder 200 from sliding further relative to the outer cylinder 100 under the action of the first elastic member or external force, thereby accurately locking the first inner cylinder 200. A trigger 520 and a transmission member 530 are used to release the locked state. The trigger 520 is located on the first flange 120, allowing the user to directly control the trigger 520. In the second or third state, the trigger 520, via the transmission member 530, drives the locking pin 510 to move circumferentially along the outer cylinder 100, thereby offsetting the locking pin 510 from the first sliding structure 220. The first inner cylinder 200 is then reset under the action of the first elastic member, returning to the first state. This simplifies and facilitates operation, enhancing the convenience of the cup holder.

[0089] In some possible implementations, see Figures 1 to 5As shown, the outer cylinder 100 of the embodiment of the present application is provided with a pivot shaft 150 on the peripheral wall, and the transmission member 530 includes a rotating ring 531, a first transmission arm 532 and a second transmission arm 533. The rotating ring 531 is rotatably mounted on the pivot shaft 150; the first transmission arm 532 and the trigger member 520 abut against each other along the axial direction of the outer cylinder 100; and the second transmission arm 533 and the locking pin 510 abut against each other along the circumferential direction of the outer cylinder 100.

[0090] It is understandable that the trigger member 520 can be a button provided on the first flange 120, and the embodiment of the present application is not limited to this. The trigger member 520 is pressed along the axial direction of the outer cylinder 100, and the trigger member 520 drives the end of the first transmission arm 532 to move downward along the axial direction of the outer cylinder 100. The first transmission arm 532 drives the rotating ring 531 to rotate, and the rotating ring 531 drives the second rotating arm to rotate. The end of the second transmission arm 533 drives the locking pin 510 to slide along the axial direction of the outer cylinder 100, so that the locking pin 510 is staggered with the first sliding structure 220, thereby releasing the lock between the first inner cylinder 200 and the outer cylinder 100.

[0091] In some possible implementations, see Figure 1 、 Figure 2 and Figures 6 to 9 As shown, the side wall of the second inner cylinder 300 of the embodiment of the present application is provided with a slide groove 310 extending along the axial direction of the outer cylinder 100, and the slide groove 310 penetrates the side wall of the second inner cylinder 300 along the radial direction of the outer cylinder 100. The first inner cylinder 200 also includes a second sliding structure 240, one end of the second sliding structure 240 is connected to the first cylinder body 210, and the other end extends to the inner side of the second inner cylinder 300 through the slide groove 310, and the second sliding structure 240 slides in cooperation with the slide groove 310.

[0092] In some embodiments, the second sliding structure 240 and the first cylinder body 210 are located on opposite sides of the second inner cylinder 300. The second inner cylinder 300 and the first inner cylinder 200 are slidably engaged with each other via the sliding groove 310 and the second sliding structure 240. The sliding groove 310 extends along the axial direction of the outer cylinder 100. The sliding groove 310 plays a certain guiding role, ensuring that the second inner cylinder 300 slides relative to the first inner cylinder 200 in the correct direction and path, which is conducive to ensuring the stability and reliability of the relative sliding of the second inner cylinder 300 and the first inner cylinder 200.

[0093] In some possible implementations, see Figure 1 、 Figure 2 and Figures 6 to 9As shown, the first inner cylinder 200 of the embodiment of the present application further includes a support plate 250, which is connected to the first cylinder body 210 and is opposite to the top wall of the second inner cylinder 300 along the axial direction of the outer cylinder 100; the cup holder further includes: a second elastic return member 600, one end of the second elastic return member 600 abuts against the support plate 250, and the other end abuts against the top wall of the second inner cylinder 300, and the second elastic return member 600 has a pre-action force on the second inner cylinder 300 to make the second inner cylinder 300 tend to the first state.

[0094] In a specific implementation, in both the first and second states, the second inner cylinder 300 is located within the first inner cavity, and is flush with the top of the first inner cylinder 200. At this point, the second elastic return member 600 provides some support for the second inner cylinder 300, preventing the second inner cylinder 300 from sliding downward along the axial direction of the first inner cylinder 200 under the pressure of the cup after the cup is placed in the cup holder, thereby ensuring stability in both the first and second states. When the cup is relatively high, the cup can continue to press downward on the second inner cylinder 300. When the pressure exceeds the elastic force of the second elastic return member 600, the second inner cylinder 300 slides relative to the first inner cylinder 200, thereby switching to the third state. Therefore, the second elastic return member 600 also provides some damping when the cup holder switches from the second state to the third state, which helps to improve the stability of the second inner cylinder 300 sliding relative to the first inner cylinder 200. When the external force acting on the second inner cylinder 300 disappears, the second inner cylinder 300 is automatically reset under the drive of the second elastic reset member 600, which is beneficial to further improve the convenience of using the cup holder.

[0095] In some possible implementations, see Figure 1 、 Figure 2 and Figures 6 to 9 As shown, the support plate 250 of the embodiment of the present application is provided with a guide column 260 extending along the axial direction of the outer cylinder 100, the top wall of the second inner cylinder 300 is provided with a sleeve extending along the axial direction of the outer cylinder 100, and one end of the second elastic return member 600 is sleeved on the outside of the guide column 260, and the other end is inserted into the inside of the sleeve.

[0096] In some embodiments, the second elastic return member 600 can be a spring, etc., and the embodiments of the present application are not limited to this. The second elastic return member 600 is mounted on the guide column, which is conducive to ensuring that the position of the second elastic return member 600 does not shift, ensuring the stability of the second elastic return member 600, and ensuring that the force applied by the second elastic return member 600 to the second inner tube 300 is along the axial direction of the outer tube 100, so that the second inner tube 300 can be accurately reset to its original position, further improving the precision of the cup holder structure.

[0097] In some possible implementations, see Figure 1 、 Figure 2 and Figures 6 to 9 As shown, the slide groove 310 of the embodiment of the present application is provided with a stop structure 320 along at least one side of the circumference of the outer cylinder 100, and the stop structure 320 is located at the bottom end of the second inner cylinder 300; the second sliding structure 240 is provided with a stop matching structure 241, and the stop matching structure 241 and the stop structure 320 are arranged opposite to each other along the axial direction of the outer cylinder 100. In the first state and the second state, the stop matching structure 241 abuts against the stop structure 320 to limit the second inner cylinder 300.

[0098] It can be understood that in the first state and the second state, the top ends of the first inner cylinder 200 and the second inner cylinder 300 remain flush. In order to prevent the second inner cylinder 300 from being higher than the first inner cylinder 200 under the action of the second elastic return member 600, it is necessary to set a stop matching structure 241 and a stop structure 320, thereby ensuring that the first inner cylinder 200 and the second inner cylinder 300 remain flush in the first state and the second state, which is beneficial to improving the aesthetics of the cup holder and at the same time improving the stability of the cup holder in the first state and the second state.

[0099] Furthermore, an elastic stopper 280 may be disposed between the second sliding structure 240 and the first tube body 210, near the bottom end of the first tube body 210. The elastic stopper 280 may be made of silicone, rubber, or the like, and is not limited in this embodiment of the present application. When the cup holder switches from the second state to the third state, the second inner tube 300 slides axially relative to the first inner tube 200. In the third state, the end of the sliding groove 310 abuts against the elastic stopper 280, forming a stopper. This prevents the second inner tube 300 from sliding further and disconnecting from the first inner tube 200, thereby improving the stability and reliability of the cup holder in the third state. The elastic stopper 280 also provides a buffering effect, preventing the second inner tube 300 from sliding too quickly and colliding with the second sliding structure 240, thereby further extending the service life of the cup holder.

[0100] In some possible implementations, see Figure 1 、 Figure 2 and Figures 6 to 9As shown, in the embodiment of the present application, the side wall of the first inner cylinder 200 is provided with a first locking hole 270 that penetrates along the radial direction of the outer cylinder 100, and the inner wall of the second inner cylinder 300 is provided with a second locking hole 330 that penetrates along the radial direction of the outer cylinder 100. The cup holder also includes a second locking member 700, which is movably arranged on the inner side of the second inner cylinder 300; wherein, in the third state, the first locking hole 270 and the second locking hole 330 are opposite to each other, and the second locking member 700 passes through the second locking hole 330 and the first locking hole 270 in sequence under the resistance of the second sliding structure 240, so that the second inner cylinder 300 maintains a fixed position relative to the first inner cylinder 200; in the first state, the second locking member 700 withdraws from the first locking hole 270 under the resistance of the outer cylinder 100, and the second inner cylinder 300 is movable relative to the first inner cylinder 200.

[0101] In a specific implementation, the second locking member 700 is used to lock the relative position between the first inner cylinder 200 and the second inner cylinder 300 in the third state, thereby preventing the second inner cylinder 300 from sliding relative to the first inner cylinder 200 due to bumps and vibrations during vehicle driving, which is beneficial to improving the stability of the cup holder in the third state. At the same time, it can also avoid mechanical wear between the second inner cylinder 300 and the first inner cylinder 200 caused by frequent shaking, which is beneficial to further improve the durability of the cup holder and extend the service life of the cup holder.

[0102] Furthermore, when the cup holder switches from the third state to the first state, the first inner cylinder 200 first slides relative to the outer cylinder 100 until the outer cylinder 100 abuts against the second locking member 700. The first inner cylinder 200 continues to slide under the action of the first elastic return member 400, so that the outer cylinder 100 pushes the second locking member 700 to exit the first lock hole 270, thereby releasing the lock. The second inner cylinder 300 is reset to be flush with the first inner cylinder 200 under the action of the second return member.

[0103] In some possible implementations, see Figure 1 、 Figure 2 and Figures 6 to 9As shown, the second locking member 700 of the embodiment of the present application includes: a locking trigger section 710, an insertion section 720, and an unlocking trigger section 730 connected in sequence. The locking trigger section 710 is pivotally connected to the inner wall of the second inner tube 300. Any two adjacent ones of the locking trigger section 710, the insertion section 720, and the unlocking trigger section 730 form an included angle. In the third state, the locking trigger section 710 is parallel to the axial direction of the outer tube 100, the insertion section 720 extends along the radial direction of the outer tube 100, and the unlocking trigger section 730 extends obliquely relative to the insertion section 720, away from the top wall of the second inner tube 300. The locking trigger section 710 is adapted to rotate relative to the second inner tube 300 under the resistance of the second sliding structure 240, so that the insertion section 720 sequentially passes through the second lock hole 330 and the first lock hole 270. The unlocking trigger section 730 is adapted to drive the trigger section to exit the first lock hole 270 under the resistance of the outer tube 100.

[0104] It should be noted that the tilted arrangement of the unlocking trigger section 730 ensures that when the first inner cylinder 200 slides axially along the outer cylinder 100, the unlocking trigger section 730 converts the axial force of the outer cylinder 100 into a force that pushes the insertion section 720 out of the first locking hole 270. This ensures that the lock between the second inner cylinder 300 and the first inner cylinder 200 is released without affecting the sliding return of the first inner cylinder 200 relative to the outer cylinder 100, achieving a coordinated unlocking and improving the precision of the cup holder structure. When the cup holder switches from the second state to the third state, the locking trigger section 710 locks the first inner cylinder 200 and the second inner cylinder 300. When switching from the third state to the first state, the unlocking trigger section 730 unlocks the first inner cylinder 200 and the second inner cylinder 300. This allows for simultaneous locking and unlocking during the switching process, eliminating the need for additional operation. This further improves the convenience and user experience of the cup holder.

[0105] See also Figure 1 As shown, an embodiment of the present application further provides an armrest box assembly, including any of the above-mentioned cup holders.

[0106] The specific structure and working principle of the cup holder are described in detail in the above embodiments and will not be described in detail here.

[0107] In the embodiment of the present application, by using the above-mentioned cup holder, when there is no need to place cups, the surface of the armrest box assembly is flat and smooth. When cups need to be placed, the cups only need to be placed on the top of the second inner tube 300 and pressed down. This can not only meet the user's need to place cups, but also ensure the aesthetics of the armrest box assembly.

[0108] See also Figure 1 As shown, an embodiment of the present application further provides a vehicle, comprising the above-mentioned armrest box assembly, or any of the above-mentioned cup holders.

[0109] In the embodiment of the present application, by using the above-mentioned armrest box assembly or cup holder, the overall aesthetics of the vehicle interior is improved. At the same time, different types of cups can be placed according to the different usage needs of users, which is conducive to improving the driving experience of the vehicle.

[0110] In summary, the cup holder, armrest box assembly and vehicle provided in the embodiment of the present application are in the first state when there is no need to place cups, and the cup holder is flush with the box surface of the armrest box assembly, thereby improving the aesthetics of the vehicle interior; when it is necessary to place cups, the cups can be placed in the middle of the cup holder and pressed downward to drive the first inner cylinder 200 to slide relative to the outer cylinder 100, thereby switching to the second state, and the locking pin 510 locks the first inner cylinder 200 and the outer cylinder 100, so that the cup holder remains in the second state; if the height of the cup is high, in order to improve the stability of the cup placement, you can continue to press downward to drive the second inner cylinder 300 to slide relative to the first inner cylinder 200, thereby switching to the third state, and the second locking member 700 locks the first inner cylinder 20 0 is locked with the second inner cylinder 300, thereby maintaining the cup holder in the third state; after use, the cup is taken out of the cup holder, and the trigger member 520 on the surface of the outer cylinder 100 is pressed. The trigger member 520 drives the locking pin 510 to unlock through the transmission member 530. The first inner cylinder 200 slides under the action of the first elastic return member 400 until the outer cylinder 100 contacts the second locking member 700. The first inner cylinder 200 continues to slide relative to the outer cylinder 100, so that the outer cylinder 100 pushes the second locking member 700 to unlock the second locking member 700. The second inner cylinder 300 is reset under the action of the second elastic return member 600 until the top ends of the outer cylinder 100, the first inner cylinder 200 and the second inner cylinder 300 are flush with each other, and the cup holder returns to the first state.

[0111] Therefore, the cup holder of the embodiment of the present application can be switched from the first state to the second state or the third state by only pressing the second inner cylinder 300 downwards, and can be switched back to the first state by pressing the trigger member 520. The operation is simple and convenient. In the second state and the third state, the first sliding structure 220, the guide structure 110, the second sliding structure 240 and the slide groove 310 are not exposed to the external environment, which is conducive to avoiding the first sliding structure 220 and the second sliding structure 240 from colliding with the cup placed in the cup holder and causing wear, thereby improving the reliability of the cup holder, reducing the wear of the cup holder, and extending the service life of the cup holder.
