Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a cup holder assembly, armrest, and vehicle. Background Technology

[0002] With the increasing popularity of automobiles, people have more and more demands for car storage functions and usage scenarios. Currently, some vehicles use pop-out cup holders in the armrests of the seats. Due to space limitations, these cup holders generally use two claws to hold the cup. However, when the vehicle encounters bumps or turns while driving, the claws cannot hold the cup stably, causing the cup to wobble. This can lead to the cup tipping over and liquid spilling, thus staining the car's interior and failing to meet the needs of holding the cup securely. Utility Model Content

[0003] The problem solved by this invention is how to improve the stability of the cup holder assembly in holding the water cup.

[0004] To address the aforementioned problems, this utility model provides a cup holder assembly, an armrest, and a vehicle.

[0005] In a first aspect, this utility model provides a cup holder assembly, including a housing having a first sidewall and a second sidewall arranged opposite to each other to form a receiving groove; two cup holder claws rotatably disposed on the first sidewall, the rotation axis of the cup holder claws being parallel to the height direction of the housing, and the two cup holder claws being used to jointly hold a water cup in the receiving groove; and a cup holder stabilizing block being telescopically disposed on the second sidewall in a direction approaching or away from the first sidewall; wherein, when the water cup is placed in the receiving groove, the two cup holder claws and the cup holder stabilizing block are sequentially arranged along the circumference of the water cup and respectively apply a squeezing force to the water cup.

[0006] The beneficial effects of this utility model cup holder assembly are: By setting the above structure, in the cup holder assembly of this embodiment, when the cup is placed in the receiving groove, the cup is located within the area enclosed by the two cup holder claws and the cup holder stabilizing block. The two cup holder claws can abut against the outer peripheral wall of the cup from the side relatively close to the first side wall, and the cup holder stabilizing block can abut against the outer peripheral wall of the cup from the side of the second side wall. The first and second side walls restrict the maximum displacement of the cup from both sides and provide a basis for the cup holder claws to clamp and the cup holder stabilizing block to press firmly, so as to ensure that the clamping force of the cup holder claws and the pressing force of the cup holder stabilizing block can act on the outer peripheral wall of the cup. In this way, by having the two cup holder claws and the cup holder stabilizing block sequentially press against the three parts of the cup along the circumference of the cup, the stability of the cup can be improved, the shaking of the cup can be effectively limited, and the tipping of the cup or spillage of liquid can be avoided. Specifically, the two cup holder claws can rotate in opposite directions in the horizontal plane to jointly grip the cup. This ensures that the cup holder claws apply clamping force symmetrically from both sides of the cup, avoiding uneven force caused by clamping from one side. At the same time, the cup holder claws can rotate and squeeze the outer wall of the cup through elastic force. In this way, the cup holder claws can automatically adjust their rotation angle according to the diameter of the cup, so that the opening angle of the two cup holder claws can adapt to the size of the cup. This allows the two cup holder claws to adapt to cups of different diameters and achieve adaptive clamping. Furthermore, the cup holder stabilizing block can also extend relative to the second side wall and squeeze the outer wall of the cup through elastic force. This allows the cup holder stabilizing block to automatically adjust its extension and contraction size according to the outer diameter of the cup. This ensures that the cup holder stabilizing block can make close contact with the outer wall of the cup while adjusting the clamping position in real time according to the diameter of the cup. No matter how the size of the cup changes, it can form an effective clamping from the side opposite to the first side wall to limit the displacement of the cup in the plane or the sway in the vertical direction, thereby improving the stability of the device when clamping the cup. In addition, since the housing may consist of only the first sidewall and the second sidewall, and the two cup holder claws can rotate into the receiving groove between the first sidewall and the second sidewall when not holding a cup, and the telescopic movement of the cup holder stabilizing block is limited to the receiving groove, the overall volume of the cup holder assembly in this embodiment is designed to be small, which is beneficial for installation in a limited space, such as by using a pull-out method to insert it into the armrest. Optionally, the cup holder assembly further includes an elastic element disposed inside the housing. One end of the elastic element is connected to the cup holder stabilizing block, and the other end of the elastic element is connected to the inner wall of the housing. The elastic element is used to drive the cup holder stabilizing block to squeeze the water cup toward the direction close to the first side wall.

[0007] Optionally, the elastic element includes a spring.

[0008] Optionally, the cup holder stabilizing block has a first arc-shaped contact surface at one end facing the first sidewall, and the first arc-shaped contact surface is adapted to fit the outer peripheral wall of the water cup.

[0009] Optionally, an opening is provided on the second sidewall, and the cup holder stabilizing block is telescopically inserted into the opening, the opening being used to guide the movement of the cup holder stabilizing block.

[0010] Optionally, the housing further has a bottom wall connected between the first side wall and the second side wall for forming the receiving groove, and the bottom wall of the receiving groove is provided with an anti-slip structure for contacting the bottom of the water cup.

[0011] Optionally, the cup holder assembly further includes a torsion spring, and each cup holder claw is provided with the torsion spring at the rotatable connection between the cup holder claw and the housing. The torsion spring is used to apply a rotational force to the cup holder claw, moving it closer to the other cup holder claw.

[0012] Optionally, the two cup holder claws are symmetrically arranged, and the inner sidewalls of the two cup holder claws are provided with a second arc-shaped contact surface, which is used to fit the outer wall of the water cup.

[0013] Secondly, this utility model provides an armrest, including the aforementioned cup holder assembly.

[0014] The beneficial effects of the armrest in this embodiment compared to the prior art are the same as those of the cup holder assembly described above, and will not be repeated here.

[0015] Thirdly, this utility model provides a vehicle including the aforementioned handrail.

[0023] like Figures 1 to 4As shown, in a first aspect, the present invention provides a cup holder assembly including a housing 10 having a first sidewall 11 and a second sidewall 12 arranged opposite to each other to form a receiving groove; two cup holder claws 20 rotatably disposed on the first sidewall 11, the rotation axis of the cup holder claws 20 being parallel to the height direction of the housing 10, and the two cup holder claws 20 being used to jointly hold a water cup in the receiving groove; a cup holder stabilizing block 30 being telescopically disposed on the second sidewall 12 in a direction approaching or away from the first sidewall 11; wherein, when the water cup is placed in the receiving groove, the two cup holder claws 20 and the cup holder stabilizing block 30 are arranged sequentially along the circumference of the water cup and respectively apply a squeezing force to the water cup.

[0024] In this embodiment, the cup holder assembly is used to be installed at the armrest of a car. The first sidewall 11 and the second sidewall 12 of the housing 1 can be arranged opposite each other in the front-rear direction of the vehicle and can be set as opposite arc-shaped sidewalls to adapt to the outer peripheral wall contour shape of the cup. The first sidewall 11 and the second sidewall 12 serve as two opposite sidewalls of the receiving groove, which limits the maximum diameter of the cup that the receiving groove can accommodate and the maximum displacement of the cup that can swing back and forth along the vehicle. The two cup holder claws 20 and the cup holder stabilizing block 30 are respectively movably arranged on the first sidewall 11 and the second sidewall 12 to jointly hold the cup placed in the receiving groove.

[0025] In this embodiment of the cup holder assembly, when the cup is placed in the receiving groove, the cup is located within the area enclosed by the two cup holder claws 20 and the cup holder stabilizing block 30. The two cup holder claws 20 can abut against the outer peripheral wall of the cup from the side relatively close to the first side wall 11, and the cup holder stabilizing block 30 can abut against the outer peripheral wall of the cup from the side of the second side wall 12. The first side wall 11 and the second side wall 12 restrict the maximum displacement of the cup from both sides of the cup and provide a basis for the cup holder claws 20 to clamp and the cup holder stabilizing block 30 to press firmly, so as to ensure that the clamping force of the cup holder claws 20 and the pressing force of the cup holder stabilizing block 30 can act on the outer peripheral wall of the cup. In this way, by having the two cup holder claws 20 and the cup holder stabilizing block 30 sequentially press and contact the three parts of the cup along the circumference of the cup, the stability of the cup can be improved, the shaking of the cup can be effectively limited, and the tipping of the cup or the spillage of liquid can be prevented. Specifically, the two cup holder claws 20 can rotate in opposite directions in the horizontal plane to jointly grip the cup. This ensures that the cup holder claws 20 apply clamping force symmetrically from both sides of the cup, avoiding uneven force distribution caused by unilateral clamping. Simultaneously, the cup holder claws 20 can rotate and compress the outer wall of the cup through elastic force. Thus, the cup holder claws 20 can automatically adjust their rotation angle according to the diameter of the cup, allowing the opening angle of the two cup holder claws 20 to adapt to the size of the cup. This enables the two cup holder claws 20 to accommodate cups of different diameters, achieving adaptive clamping. Furthermore, the cup holder stabilizing block 30 can also extend relative to the second side wall 12 and press against the outer wall of the cup using elastic force. This allows the cup holder stabilizing block 30 to automatically adjust its extension and retraction size according to the outer diameter of the cup, ensuring that the cup holder stabilizing block 30 can make close contact with the outer wall of the cup while adjusting its clamping position in real time according to the diameter of the cup. Regardless of the size of the cup, it can form an effective clamping position from the side opposite to the first side wall 11, limiting the displacement of the cup in the plane or its sway in the vertical direction, thereby improving the stability of the device when holding the cup. In addition, since the housing 1 may only include the first side wall 11 and the second side wall 12, and the two cup holder claws 20 can rotate into the receiving groove between the first side wall 11 and the second side wall 12 when not holding the cup, and the extension and retraction of the cup holder stabilizing block 30 is limited only to the receiving groove, the overall volume of the cup holder assembly in this embodiment is relatively small, which is beneficial for installation in limited spaces, such as by using a pull-out method to insert it into the armrest. Optionally, the cup holder assembly also includes an elastic element 40, which is disposed inside the housing 10. One end of the elastic element 40 is connected to the cup holder stabilizing block 30, and the other end of the elastic element 40 is connected to the inner wall of the housing 10. The elastic element 40 is used to drive the cup holder stabilizing block 30 to squeeze the cup toward the direction close to the first side wall 11.

[0026] By setting the above structure, one end of the elastic element 40 is connected to the cup holder stabilizing block 30, and the other end is connected to the inner wall of the housing 10. Its own elastic deformation characteristics can apply a driving force toward the second side wall 12 to the cup holder stabilizing block 30. When the cup is placed into the receiving space and squeezes the cup holder stabilizing block 30, the elastic element 40 is compressed and generates elastic force. This elastic force acts in the opposite direction on the cup holder stabilizing block 30 to form a continuous pressing force. Even if the cup is slightly displaced due to bumps while the vehicle is moving, the elastic force of the elastic element 40 can push the cup holder stabilizing block 30 to move with the cup in real time, always keeping the cup holder stabilizing block 30 in close contact with the outer wall of the cup, and avoiding the cup shaking due to the gap between the cup holder stabilizing block 30 and the cup.

[0027] Meanwhile, the elastic force of the elastic element 40 changes with its own deformation. When water cups of different diameters are placed in, if the water cup diameter is larger, the cup holder stabilizing block 30 will move a farther distance after being squeezed, the elastic element 40 will deform more, and the resulting clamping force will be enhanced to ensure effective clamping of the larger diameter water cup. If the water cup diameter is smaller, the cup holder stabilizing block 30 will move a shorter distance, the elastic element 40 will deform less, and the clamping force will be weakened accordingly to avoid deformation or damage to the smaller diameter water cup due to excessive clamping force. This adaptive adjustment allows the clamping force of the cup holder stabilizing block 30 to be precisely matched with the size of the water cup, thereby further improving the stability of the water cup clamping. Optionally, the elastic element 40 includes a spring.

[0028] By setting up the above structure, the spring can withstand repeated deformation caused by vibration and bumps during vehicle operation for a long time, thereby maintaining the initial clamping force output. This ensures that the cup holder assembly can stably hold the cup, reducing the need for later maintenance and thus improving long-term stability. Meanwhile, when the vehicle travels on a bumpy road and the cup is subjected to a momentary impact from the bumps, if the cup is squeezed towards the cup holder stabilizing block 30, the spring can slowly absorb the impact energy through compression deformation, preventing the cup holder stabilizing block 30 from colliding with the cup and causing the cup to rebound; if the cup bounces away from the stabilizing block, the spring can push the stabilizing block to move with the cup, preventing the two from separating. This can significantly reduce the instantaneous displacement of the cup, thereby ensuring the stability of the device in holding the cup as much as possible. In other embodiments, the cup holder stabilizing block 30 can be made directly from a flexible and stretchable material such as rubber, thus eliminating the need for the elastic element 40 structure.

[0029] Optionally, the cup holder stabilizing block 30 has a first arc-shaped contact surface 31 at one end facing the first side wall 11, and the first arc-shaped contact surface 31 is used to fit the outer peripheral wall of the cup.

[0030] By setting the above structure, the first arc-shaped contact surface 31 and the curved surface of the outer wall of the water cup are both arc-shaped surfaces. The two shapes are compatible, which can significantly increase the contact area between the cup holder stabilizing block 30 and the water cup. The larger contact area can make the clamping force of the cup holder stabilizing block 30 evenly distributed in the contact area of ​​the outer wall of the water cup, avoiding deformation of the water cup due to excessive local force.

[0031] Furthermore, for small-diameter cups, the inner area of ​​the first arc-shaped contact surface 31 can fit against the outer wall of the cup; for large-diameter cups, the outer area of ​​the first arc-shaped contact surface 31 can fit against the outer wall of the cup. This ensures that regardless of the cup diameter, the cup holder stabilizing block 30 can effectively fit against the outer wall of the cup through the first arc-shaped contact surface 31, thereby improving the clamping and fitting stability of cups of various sizes. Optionally, an opening 121 is provided on the second side wall 12, and the cup holder stabilizing block 30 is telescopically inserted into the opening 121. The opening 121 is used to guide the movement of the cup holder stabilizing block 30.

[0032] By setting the above structure, the opening 121 of the second sidewall 12 provides a moving channel for the cup holder stabilizing block 30, and can restrict the cup holder stabilizing block 30 to move back and forth only in a direction perpendicular to the second sidewall 12, so as to prevent the cup holder stabilizing block 30 from moving out of the preset path due to vehicle bumps and vibrations. At the same time, when the stabilizing block moves in the opening 121, the inner sidewall of the opening 121 can form a bidirectional limit on the stabilizing block, preventing it from swaying up and down or left and right during the movement, so that the stabilizing block always maintains a stable moving state.

[0033] Optionally, the housing 10 also has a bottom wall of the groove connected between the first side wall 11 and the second side wall 12 to form a receiving groove. The bottom wall of the receiving groove is also provided with an anti-slip structure 13, which is used to contact the bottom wall of the water cup.

[0034] By setting the above structure, when the anti-slip structure 13 contacts the bottom of the water cup, the friction coefficient between the two can be significantly increased. When the vehicle is in motion and there are conditions such as turning, rapid acceleration, or sudden braking, the water cup is prone to lateral sliding along the bottom wall of the groove due to inertia. The friction between the anti-slip structure 13 and the water cup can directly offset these inertial forces, reducing the risk of displacement of the water cup from the root, thereby enhancing the overall clamping stability. In this embodiment, the anti-slip structure 13 can be made of silicone.

[0035] Optionally, the cup holder assembly also includes a torsion spring 50, with each cup holder claw 20 having a torsion spring 50 at the rotatable connection between it and the housing 10. The torsion spring 50 is used to apply a rotational force to the cup holder claw 20, bringing it closer to the other cup holder claw 20.

[0036] By setting the above structure, each cup holder claw 20 is equipped with a torsion spring 50 at its rotating connection. When the torsion spring 50 is in an elastic deformation state, it applies a rotational force to the cup holder claw 20, which is close to the other cup holder claw 20. When the cup is not placed between the two cup holder claws 20, the two cup holder claws 20 maintain a preset closed tendency under the action of the torsion spring 50. When the cup is placed between the two cup holder claws 20 and the cup holder claws 20 are squeezed, the cup holder claws 20 rotate in the opposite direction, which causes the torsion spring 50 to deform. The deformed torsion spring 50 acts in the opposite direction on the cup holder claws 20 through its elastic force, forming a continuous clamping pre-tightening force. This ensures that the cup holder claws 20 are always tightly attached to the outer wall of the cup. Even if the cup has a slight radial displacement due to bumps, the elastic force of the torsion spring 50 can push the cup holder claws 20 to follow in real time, avoiding gaps between the cup holder claws 20 and the cup.

[0037] Optionally, the two cup holder claws 20 are symmetrically arranged, and the inner sidewalls of the two cup holder claws 20 are provided with a second arc-shaped contact surface 21, which is used to fit the outer wall of the cup.

[0038] In this embodiment, the two cup holder claws 20 are symmetrically arranged along a symmetrical plane, wherein the symmetrical plane is parallel to the axis of rotation of the cup holder claw 20 and perpendicular to the first side wall 11. Each cup holder claw 20 has an arc-shaped structure and one end is rotatably connected to the first side wall 11. The inner side walls of the two cup holder claws 20, that is, the side of the two cup holder claws 20 facing each other, are both arc-shaped surfaces, namely the second arc-shaped contact surface 21. In this way, the two cup holder claws 20 can form the effect of holding the water cup.

[0039] By setting the above structure, the second arc-shaped contact surface 21 is height-adapted to the outer wall of the cup. For small-diameter cups, the inner area of ​​the second arc-shaped contact surface 21 can fit against the outer wall of the cup; for large-diameter cups, the outer area of ​​the second arc-shaped contact surface 21 can fit against the outer wall of the cup. This ensures that regardless of the cup diameter, the second arc-shaped contact surface 21 can effectively fit against the outer wall of the cup, thereby improving the clamping stability of cups of various sizes and ensuring that the clamping force is stably applied to the cup.

[0040] Secondly, the present invention provides an armrest that includes the aforementioned cup holder assembly.

[0041] The beneficial effects of the armrest in this embodiment compared to the prior art are the same as those of the cup holder assembly described above, and will not be repeated here.

[0042] Optionally, the armrest also includes a housing with a receiving cavity. The cup holder assembly can be moved along the length of the housing 10 and disposed in the receiving cavity. For example, the front end of the housing has an opening communicating with the receiving cavity. When a water cup needs to be placed in the housing, the cup holder assembly can be pulled out of the receiving cavity along the length of the housing 10 to form a support space for placing the water cup. When not in use, the cup holder assembly can be pushed back into the receiving cavity to save space and prevent the cup holder assembly from being exposed and causing bumps.

[0043] Thirdly, the present invention provides a vehicle including the aforementioned handrail.

[0044] The beneficial effects of the vehicle in this embodiment compared to the prior art are the same as those of the cup holder assembly described above, and will not be repeated here.

[0045] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
