DETAILED DESCRIPTION

[0024] In order to make the technical solution and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] The utility model provides a technical solution: Figure 1-6 The utility model discloses a vehicle armrest assembly, including a cup holder 1 fixedly installed in the vehicle armrest assembly, the cup holder 1 is mainly divided into two parts, a mounting plate 11 and two fixing cylinders 12, the two fixing cylinders 12 are fixedly installed on the mounting plate 11, and the top of each fixing cylinder 12 is coplanar with the top side of the mounting plate 11, a buffer mechanism 2 is provided in the top opening of the fixing cylinder 12, and an adsorption mechanism 3 is provided at the bottom of the fixing cylinder 12.

[0026] In this embodiment, when the improved automobile armrest assembly is in use, the operator inserts the bottom end of the cup into the opening of the fixed cylinder 12. Due to the weight of the cup itself, the outer ring edge of the bottom end of the cup conflicts with the buffer mechanism 2, and the buffer mechanism 2 automatically adjusts the size of the top opening of the fixed cylinder 12, so that the cup can slide directly into the fixed cylinder 12. At the same time, the buffer mechanism 2 provides soft support for the top of the cup, thereby offsetting the inertial force when the cup shakes, and at the same time, the adsorption mechanism 3 cooperates with the buffer mechanism 2 to apply a strong resistance to the cup, so that the cup will not slide out of the fixed cylinder 12.

[0027] In a further preferred embodiment of the present invention, Figure 2 As shown, the buffer mechanism 2 includes a soft ring 21, which is disposed in the top opening of the corresponding fixed cylinder 12, and the outer peripheral wall of the soft ring 21 is fixedly connected to the inner wall of the opening of the corresponding fixed cylinder 12, and the interior of the soft ring 21 is hollow and filled with air;

[0028] In the present embodiment, when the cup is placed into the fixed tube 12, the size of the opening at the top of the fixed tube 12 can be automatically adjusted through the contraction deformation of the soft ring 21, and due to the push of the soft ring 21 by the internal gas of the soft ring 21, the soft ring 21 fits tightly against the outer wall of the cup to support and limit the top of the cup, and the soft ring 21 cooperates with the cup to automatically close the opening at the top of the fixed tube 12, thereby forming a closed space inside the fixed tube 12.

[0029] In a further preferred embodiment of the present invention, Figure 2-4 As shown, the top side of the soft ring 21 is an inclined surface with the outer ring wall inclined toward the center, the inner ring wall of the soft ring 21 is an arc surface, and a plurality of soft partitions 22 are fixedly installed in a circular array inside the soft ring 21;

[0030] In this embodiment, the inclined surface on the top side of the soft ring 21 is set so that the top opening of the soft ring 21 forms a flared opening, which facilitates the insertion of the bottom end of the cup into the inner hole of the soft ring 21, and the setting of the soft partition 22 can divide the soft ring 21 into multiple spaces.

[0031] In a further preferred embodiment of the present invention, Figure 3 As shown, a plurality of connecting holes 23 are provided on the soft partition plate 22 from top to bottom, and the distance between the connecting hole 23 and the inner wall of the corresponding fixing cylinder 12 is smaller than the distance between the connecting hole 23 and the inner ring wall of the soft ring 21;

[0032] In this embodiment, when the cup is tilted and shaken to one side, one side of the soft ring 21 is deformed and contracted due to the pressure of the cup, and due to the obstruction of the soft partition 22 and the limited amount of gas passing through the connecting hole 23, the internal pressure of the contracted part of the soft ring 21 gradually increases, thereby exerting a gradually increasing reaction force on the cup to offset the inertial force when the cup is shaken. At the same time, since the cup can still be tilted to a certain extent, the water in the cup will not move in large quantities to the connection between the cup cover and the cup body due to the inertial force during shaking, thereby preventing water from overflowing from the gap between the cup cover and the cup body when there is a gap between the cup cover and the cup body.

[0033] In a further preferred embodiment of the present invention, Figure 2 and Figure 6 As shown, the adsorption mechanism 3 includes a magnetic plate 31, which is arranged below the corresponding soft ring 21, and the outer peripheral wall of the magnetic plate 31 contacts the inner wall of the corresponding fixed cylinder 12, and an annular groove 32 is provided on the outer peripheral wall of the magnetic plate 31, and a sealing ring 33 is slidably installed in the annular groove 32, and the outer ring wall of the sealing ring 33 contacts the inner wall of the corresponding fixed cylinder 12;

[0034] In this embodiment, when the cup is inserted into the fixed cylinder 12, due to the mutual interference between the cup and the magnetic plate 31, the magnetic plate 31 can move down with the cup, and at the same time, the magnetic plate 31 cooperates with the sealing ring 33 and the weight of the cup itself to exert a thrust on the gas at the bottom side of the magnetic plate 31;

[0035] After the cup is inserted into the fixed tube 12, the fixed tube 12 cooperates with the soft ring 21 to block the top opening of the fixed tube 12, thereby forming a relatively closed space in the fixed tube 12, and due to the downward movement of the magnetic plate 31, the space between the magnetic plate 31 and the soft ring 21 is expanded, thereby forming a negative pressure chamber in the fixed tube 12, applying a restraining force to the cup into the fixed tube 12, making it difficult for the cup to slide out of the fixed tube 12.

[0036] In a further preferred embodiment of the present invention, Figure 2 As shown, the interior of the magnetic plate 31 is hollow, and a magnetic ring 34 is provided above the magnetic plate 31. The magnetic ring 34 is fixedly connected to the bottom side of the corresponding soft ring 21 and the inner wall of the corresponding fixed cylinder 12, and the magnetic ring 34 is gap-matched with the magnetic plate 31.

[0037] In this embodiment, after the cup is pulled out of the fixed tube 12, the soft ring 21 automatically expands and resets due to the push of the internal gas. At the same time, due to the attraction between the magnetic ring 34 and the magnetic plate 31, the magnetic plate 31 slowly moves up and resets, and scrapes off the dust on the inner wall of the fixed tube 12 and moves with the magnetic plate 31. The operator does not need to perform other operations.

[0038] It should be noted that the hollow setting of the magnetic plate can greatly reduce the weight of the magnetic plate.

[0039] In a further preferred embodiment of the present invention, Figure 2 and Figure 5 As shown, a circular hole 35 is provided on the bottom side of the fixed cylinder 12, a pressure limiting valve 36 is fixedly installed in the circular hole 35, and the top end of the pressure limiting valve 36 is inserted into the corresponding fixed cylinder 12, and the bottom end of the pressure limiting valve 36 is gap-matched with the bottom end opening of the corresponding circular hole 35, and a plurality of exhaust grooves 37 are provided on the bottom side of the fixed cylinder 12 in a circumferential array, and the interior of each exhaust groove 37 is communicated with the interior of the bottom end opening of the corresponding circular hole 35;

[0040] In this embodiment, when the magnetic plate 31 moves downward, a pressure difference is generated at both ends of the pressure limiting valve 36, so that the gas below the magnetic plate 31 passes through the pressure limiting valve 36 and is discharged into the circular hole 35, and then flows into the exhaust groove 37 and is discharged from the fixed cylinder 12 through the opening of the exhaust groove 37;

[0041] The provision of the exhaust groove 37 can expand the bottom opening of the circular hole 35 , thereby preventing the exhaust of the gas in the fixed tube 12 from being affected by the shielding of foreign objects below the circular hole 35 .

[0042] In a further preferred embodiment of the present invention, Figure 2 and Figure 6 As shown, two guide rods 38 are relatively slidably installed on the magnetic plate 31, and the two ends of each guide rod 38 are respectively fixedly connected to the corresponding magnetic ring 34 and the inner wall of the corresponding fixed cylinder 12, and a limit plate 39 is fixedly sleeved on the outer peripheral side of the guide rod 38, and the limit plate 39 is located on the top side of the magnetic plate 31;

[0043] In this embodiment, during the downward movement of the magnetic plate 31, due to the mutual interference between the guide rod 38 and the magnetic plate 31, the magnetic plate 31 can only move in a linear trajectory in the up and down directions, thereby avoiding the generation of an inclination angle during the movement of the magnetic plate 31;

[0044] During the upward movement of the magnetic plate 31, due to the mutual interference between the limit plate 39 and the magnetic plate 31, there is always a certain gap between the magnetic plate 31 and the magnetic ring 34, thereby avoiding that the distance between the magnetic plate 31 and the magnetic ring 34 is too small, resulting in excessive attraction between the magnetic plate 31 and the magnetic ring 34, affecting the water cup to press the magnetic plate 31 downward.

[0045] Working principle: When the improved automobile armrest assembly is in use, the operator inserts the bottom end of the cup into the opening of the fixed cylinder 12. Due to the weight of the cup itself, the outer ring edge of the bottom end of the cup and the top inclined surface of the soft ring 21 conflict with each other, and the inside of the soft ring 21 bends and contracts into the fixed cylinder 12, automatically expanding the top opening of the fixed cylinder 12, so that the bottom of the cup automatically slides into the fixed cylinder 12. Subsequently, due to the mutual conflict between the bottom side of the cup and the magnetic plate 31, the magnetic plate 31 slides downward along the guide rod 38, thereby cooperating with the sealing ring 33 to press the gas at the bottom of the fixed cylinder 12 downward, so that a large pressure difference is generated at both ends of the pressure limiting valve 36, and then the gas at the bottom of the fixed cylinder 12 quickly passes through the pressure limiting valve 36 and is discharged into the circular hole 35. Finally, the gas flows into the exhaust groove 37 and is discharged from the opening of the exhaust groove 37.

[0046] It should be noted that, due to the push of the soft ring 21 by the gas inside the soft ring 21, the inner ring wall of the soft ring 21 is closely fitted with the outer peripheral wall of the cup, so that a certain friction force is generated between the soft ring 21 and the outer peripheral wall of the cup, and the outer peripheral side of the cup supports and limits the top of the cup;

[0047] It should be noted that after the cup is inserted into the fixed tube 12, the fixed tube 12 cooperates with the soft ring 21 to block the top opening of the fixed tube 12, so that a relatively closed space is formed in the fixed tube 12, and due to the downward movement of the magnetic plate 31, the space between the magnetic plate 31 and the soft ring 21 is expanded, thereby forming a negative pressure chamber in the fixed tube 12;

[0048] When the car is shaking while driving, the cup will not shake violently because the soft ring 21 supports the top of the cup.

[0049] It should be noted that during the above-mentioned cup shaking process, when the cup tilts and shakes to one side, one side of the soft ring 21 is deformed and contracted due to the pressing of the cup, and due to the obstruction of the soft partition 22 and the limited amount of gas passing through the connection hole 23, the internal pressure of the contracted part of the soft ring 21 gradually increases, thereby exerting a gradually increasing reaction force on the cup to offset the inertia force of the cup when the cup is shaken. At the same time, since the cup can still be tilted to a certain extent, the water in the cup will not move to the connection between the cup cover and the cup body in large quantities due to the inertia force during shaking, thereby avoiding water overflowing from the gap between the cup cover and the cup body when there is a gap between the cup cover and the cup body. Finally, after the inertia force of the cup disappears, the cup is straightened by the expansion and contraction deformation of various parts of the soft ring 21.

[0050] When the cup is in the fixed tube 12 and shakes, if the cup slides out of the fixed tube 12, the space in the fixed tube 12 will expand, thereby increasing the negative pressure at the bottom of the fixed tube 12. The negative pressure adsorption and the friction between the soft ring 21 and the cup exert a great resistance on the cup, so that the cup will not slide out of the fixed tube 12. After the inertia force of the cup disappears, the cup will automatically reset itself through its own gravity and the suction force of the negative pressure chamber inside the fixed tube 12 on the cup.

[0051] It should be noted that, in the process of the cup sliding out of the fixed cylinder 12, due to the small attraction between the magnetic plate 31 and the magnetic ring 34, the magnetic plate 31 will only slide slightly upward, and in the process of the magnetic plate 31 sliding upward, due to the limited amount of gas passing through the pressure limiting valve 36, the external gas will not flow into the fixed cylinder 12 quickly, so that negative pressure is formed on the bottom side of the magnetic plate 31, further slowing down the upward movement speed of the magnetic plate 31, thereby preventing the magnetic plate 31 from moving upward with the cup and affecting the suction and pulling of the cup by the negative pressure chamber in the fixed cylinder 12;

[0052] After the cup is pulled out of the fixing tube 12, the soft ring 21 automatically expands and resets due to the push of the internal gas, and at the same time, due to the attraction between the magnetic ring 34 and the magnetic plate 31, the magnetic plate 31 slowly moves upward and resets;

[0053] When cleaning the cup holder 1, since the top of the fixed cylinder 12 is shielded by the soft ring 21 and only has a small opening, large foreign objects will not fall into the fixed cylinder 12, and small foreign objects that fall into the fixed cylinder will only be located in the top opening of the fixed cylinder 12 due to the blocking of the magnetic plate 31. The operator only needs to insert a finger into the opening of the fixed cylinder 12 to take the small foreign objects out of the top opening of the fixed cylinder 12.

[0054] When cleaning the dust on the cup holder 1, the operator can clean the mounting plate 11 by wiping the mounting plate 11 with a cloth, and then the operator inserts the cloth into the top opening of the fixed tube 12 with a finger, and wipes the soft ring 21, the magnetic plate 31 and the inner wall of the opening of the fixed tube 12 to complete the cleaning of the fixed tube 12. The operator does not need to insert the palm of the operator into the fixed tube 12, and the cleaning of the dust in the fixed tube 12 will not be affected due to the difficulty of inserting the palm into the fixed tube 12 due to the large size of the palm.

[0055] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected.
