[0068] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.

[0069] Reference below Figure 1-Figure 16 A base assembly 100 of an armrest according to an embodiment of the present invention is described.

[0070] like Figure 1As shown, the base assembly 100 of the armrest according to the first embodiment of the utility model includes: a base 10, a first locking mechanism 20 and a second locking mechanism 30. The base 10 is formed with a receiving groove 11, and the receiving groove 11 is used to receive the cup holder assembly 40. The first locking mechanism 20 is arranged on the base 10, and is used to lock the cup holder assembly 40 in the receiving groove 11. The second locking mechanism 30 is arranged on the base 10, and is used to lock the first locking mechanism 20, so as to prevent the first locking mechanism 20 from unlocking the cup holder assembly 40.

[0071] Specifically, the traditional cup holder assembly can be unlocked by pressing it. When the armrest is closed, the cup holder assembly may pop out due to misoperation. Some cup holder assemblies are equipped with a gravity lock assembly to prevent the cup holder assembly from popping out due to misoperation. When the vehicle is running on a bumpy road and the cup holder assembly is in a retracted or laid down state, the inertia of the cup holder assembly will generate an impact force on the gravity lock assembly, causing the gravity lock assembly to be damaged and the cup holder assembly to pop out, which affects the service life of the cup holder assembly and also poses a danger to passengers.

[0072] Therefore, the base assembly 100 of the armrest is mainly composed of a base 10, a first locking mechanism 20 and a second locking mechanism 30. The base 10 is provided with a receiving groove 11, which can provide a receiving space for the cup holder assembly 40. The first locking mechanism 20 is connected to the base 10, so that the first locking mechanism 20 will not be affected by the movement of the cup holder assembly 40. The cup holder assembly 40 is located in the receiving groove 11 of the base 10, so that the first locking mechanism 20 can lock the cup holder assembly 40 in the receiving groove 11, thereby preventing the cup holder assembly 40 from popping out of the receiving groove 11.

[0073] Furthermore, the second locking mechanism 30 is disposed on the base 10, so that the cup holder assembly 40 can avoid affecting the second locking mechanism 30, and the movement of the cup holder assembly 40 will not change the position and force of the second locking mechanism 30. When the base assembly 100 is in the retracted state and the base assembly is laid down at a certain angle, the second locking mechanism 30 and the first locking mechanism 20 maintain a limited position matching state due to gravity, so that the second locking mechanism 30 can lock the first locking mechanism 20. When the cup holder assembly 40 is pressed or subjected to impact force and tends to pop outward, the first locking mechanism 20 and the second locking mechanism 30 are locked with each other, so that the first locking mechanism 20 can be prevented from unlocking the cup holder assembly 40.

[0074] Therefore, the first locking mechanism 20 and the second locking mechanism 30 in the base assembly 10 will not change their positions and force states due to the movement of the cup holder assembly 40, and the first locking mechanism 20 can be prevented from unlocking the cup holder assembly 40, thereby preventing the cup holder assembly 40 from popping out of the receiving slot 11 due to accidental touching.

[0075] According to some embodiments of the present invention, Figure 2-Figure 4 As shown, the first locking mechanism 20 can be rotatably disposed on the base 10, and the first locking mechanism 20 locks and unlocks the cup holder assembly 40 by its own rotation, and the second locking mechanism 30 can be movably disposed on the base 10, and the second locking mechanism 30 locks and unlocks the first locking mechanism 20 by its own movement.

[0076] When the first locking mechanism 20 and the second locking mechanism 30 are in the unlocked state, the first locking mechanism 20 rotates relative to the base 10 when the cup holder assembly 40 is pressed, and when the first locking mechanism 20 rotates to a position locked with the cup holder assembly 40, the first locking mechanism 20 locks the cup holder assembly 40. When the first locking mechanism 20 rotates to a position disengaged from the cup holder assembly 40, the first locking mechanism 20 unlocks the cup holder assembly 40.

[0077] In addition, the second locking mechanism 30 can move on the base 10. When the second locking mechanism 30 moves to a position where it is limitedly matched with the first locking mechanism 20, the second locking mechanism 30 can lock the first locking mechanism 20. When the second locking mechanism 30 moves to a position where it is disengaged from the first locking mechanism 20, the second locking mechanism 30 can unlock the first locking mechanism 20.

[0078] According to some embodiments of the present invention, Figure 3 and Figure 4 As shown, the second locking mechanism 30 locks and unlocks the first locking mechanism 20 using gravity.

[0079] Among them, when the base assembly 100 is in the retracted state, the second locking mechanism 30 moves to a position for locking with the first locking mechanism 20 due to the action of gravity, which can prevent the first locking mechanism 20 from rotating due to the movement of the cup holder assembly 40, thereby enabling the second locking mechanism 30 to lock the first locking mechanism 20.

[0080] When the base assembly 100 is completely in a laid-down state, the second locking mechanism 30 moves to a position disengaged from the first locking mechanism 20 due to gravity, and the cup holder assembly 40 drives the first locking mechanism 20 to rotate during the pop-up process, thereby enabling the second locking mechanism 30 to unlock the first locking mechanism 20.

[0081] According to some embodiments of the present invention, Figure 3 and Figure 4 As shown, the base 10 is formed with a sliding hole 12, and the second locking mechanism 30 can be slidably disposed in the sliding hole 12, and there is an angle between the sliding hole 12 and the gravity direction.

[0082] Among them, the sliding hole 12 is a cylindrical hole. When the base assembly 100 completes the two actions of folding and laying down, the second locking mechanism 30 can slide back and forth in the sliding hole 12, so that the sliding hole 12 can form a sliding trajectory of the second locking mechanism 30, so that the sliding hole 12 can form an angle with the gravity direction of the second locking mechanism 30.

[0083] Furthermore, when the base assembly 100 is in the stowed state, the angle formed by the gravity direction of the second locking mechanism 30 and the direction of the sliding hole 12 away from the first locking mechanism 20 is a blunt angle, so that the second locking mechanism 30 and the first locking mechanism 20 are in a locked state. When the base assembly 100 is in the process of being laid down, the angle formed by the gravity direction of the second locking mechanism 30 and the direction of the sliding hole 12 away from the first locking mechanism 20 gradually decreases from an obtuse angle, and the second locking mechanism 30 and the first locking mechanism 20 are still in a locked state for a period of time during the laying down process, so that when the base assembly 100 is tilted due to misoperation and external force impact, the cup holder assembly 40 can also be prevented from popping out.

[0084] When the base assembly 100 is in a laid-down state, the angle formed by the gravity direction of the second locking mechanism 30 and the direction of the sliding hole 12 away from the first locking mechanism 20 is an acute angle, so that the second locking mechanism 30 and the first locking mechanism 20 are in a locked state.

[0085] According to some embodiments of the present invention, Figure 3 and Figure 4 As shown, the base 10 is formed with an installation cavity 13, which is connected to the sliding hole 12, and the second locking mechanism 30 extends into the installation cavity 13. The inner wall of the installation cavity 13 blocks the second locking mechanism 30, thereby preventing the second locking structure from escaping from the sliding hole 12.

[0086] The installation cavity 13 can provide a storage space for the second locking mechanism 30 , and the installation cavity 13 is connected to the sliding hole 12 , so that the second locking mechanism 30 can be easily extended out of the sliding hole 12 and locked with the first locking mechanism 20 .

[0087] Furthermore, the inner wall of the installation cavity 13 close to the sliding hole 12 can prevent the second locking mechanism 30 from escaping from the sliding hole 12 , thereby limiting the movement range of the second locking mechanism 30 .

[0088] According to the specific embodiment of the utility model, Figure 3 and Figure 4As shown, the second locking mechanism 30 includes: a head 31 and a rod 32, the head 31 is arranged in the installation cavity 13, the cross-sectional area of ​​the head 31 is larger than the cross-sectional area of ​​the sliding hole 12, the rod 32 is connected to the head 31, the cross-sectional area of ​​the rod 32 is smaller than the cross-sectional area of ​​the head 31, and the rod 32 can be slidably arranged in the sliding hole 12.

[0089] Specifically, the second locking mechanism 30 is mainly composed of a head 31 and a rod 32. When the base assembly 100 is in the retracted state, only the head 31 is located in the installation cavity 13. When the base assembly 100 is in the laid-down state, the head 31 and a part of the rod 32 are located in the installation cavity 13. The head 31 is a nut structure, and the rod 32 is a stud structure. The cross-sectional area of ​​the head 31 is set to be larger than the cross-sectional area of ​​the sliding hole 12, so as to prevent the head 31 from sliding out of the sliding hole 12.

[0090] Furthermore, the cross-sectional area of ​​the rod portion 32 is smaller than the cross-sectional area of ​​the head portion 31 , so that the rod portion 32 can slide in the sliding hole 12 , and the head portion 31 can only move in the installation cavity 13 , thereby playing a role of limiting.

[0091] According to some embodiments of the present invention, Figure 4 and Fig.14 As shown, the base 10 includes: a first base body 14, a second base body 15 and a cover body 16, the second base body 15 is connected to the first base body 14, the mounting cavity 13 and the sliding hole 12 are arranged on the second base body 15, the side of the mounting cavity 13 away from the first base body 14 is open, the cover body 16 is arranged on the second base body 15, and the cover body 16 covers the open side of the mounting cavity 13, wherein the first base body 14, the second base body 15 and the cover body 16 are arranged along the thickness direction of the base 10, and the second base body 15 is located between the first base body 14 and the cover body 16.

[0092] The first seat body 14 is the upper shell of the base assembly 100, and the second seat body 15 is the lower shell of the base assembly 100. The second seat body 15 is connected to the first seat body 14 and can be used to close the cup holder assembly 40. The installation cavity 13 and the sliding hole 12 are arranged on the second seat body 15, so that the installation cavity 13 and the sliding hole 12 are integrated with the second seat body 15. When the second seat body 15 switches between the retracted state and the laid-down state, the installation cavity 13 and the sliding hole 12 move synchronously with the second seat body 15, and the second locking mechanism 30 also moves in the sliding hole 12 at the same time, so that the second locking mechanism 30 can be locked and unlocked in time.

[0093] In addition, the cover body 16 seals the open side of the mounting cavity 13, which can prevent the second locking mechanism 30 from falling off from the open side, control the effective stroke of the second locking mechanism 30, and also serve as a stop, thereby preventing the rod 32 of the second locking mechanism 30 from sliding out of the sliding hole 12.

[0094] According to some embodiments of the present invention, Figure 2 and Figure 3 As shown, the second seat body 15 includes: a seat plate 151 and a first boss 152 . The first boss 152 is disposed on the seat plate 151 and is suitable for protruding toward the cup holder assembly 40 . The sliding hole 12 and the mounting cavity 13 are formed on the first boss 152 .

[0095] The first boss 152 is connected to the seat plate 151 and is protruded toward the cup holder assembly 40, so that the first boss 152 can be easily formed with the mounting cavity 13 inside. In addition, a sliding hole 12 is provided in the first boss 152, so that the second locking mechanism 30 can be locked with the first locking mechanism 20 through the sliding hole 12.

[0096] According to some embodiments of the present invention, Figure 2 and Figure 4 As shown, the first boss 152 is formed with an inclined plate portion 153 which is inclined relative to the seat plate 151 , and the sliding hole 12 is formed in the inclined plate portion 153 , and the sliding hole 12 is perpendicular to the inclined plate portion 153 .

[0097] Among them, the setting of the inclined plate portion 153 can ensure the relative position of the second locking mechanism 30 and the first locking mechanism 20. During the process of folding and laying down the base assembly 100, due to the inclined setting of the inclined plate portion 153 relative to the seat plate 151, the relative position of the second locking mechanism 30 and the first locking mechanism 20 can always be maintained, thereby realizing accurate locking and unlocking of the second locking mechanism 30 and the first locking mechanism 20.

[0098] In addition, the sliding hole 12 is formed on the inclined plate portion 153, so that the inclined plate portion 153 can prevent the head 31 of the second locking mechanism 30 from sliding out of the sliding hole 12, thereby achieving a stopping effect, and the sliding hole 12 is perpendicular to the inclined plate portion 153, which can ensure that the matching position of the second locking mechanism 30 and the first locking mechanism 20 does not deviate, thereby improving the accuracy of the locking position of the second locking mechanism 30 and the first locking mechanism 20.

[0099] According to some embodiments of the present invention, Figure 4 As shown, a protrusion 154 is formed on a surface of the inclined plate portion 153 that is away from the installation cavity 13 , and the sliding hole 12 passes through the protrusion 154 .

[0100] Among them, the setting of the protrusion 154 can extend the depth of the sliding hole 12, so that a sliding track can be provided for the second locking mechanism 30, thereby preventing the second locking mechanism 30 from swinging during the sliding process in the sliding hole 12, and ensuring that the second locking mechanism 30 does not deviate from the locking position during the sliding process.

[0101] According to the specific embodiment of the utility model, Figure 4 As shown, the cover body 16 is snap-fitted with the second base body 15 .

[0102] Specifically, one of the cover body 16 and the second base body 15 is set as a buckle, and the other of the cover body 16 and the second base body 15 is set as a slot. When the cover body 16 is provided with a buckle, two buckles can be provided. Correspondingly, the second base body 15 is provided with a slot, and there are also two slots. The buckle and the slot are limitedly matched, so that the installation and disassembly of the cover body 16 and the second base body 15 can be facilitated, and the replacement of the second locking mechanism 30 can also be facilitated.

[0103] In addition, a sound insulation pad may be provided between the cover body 16 and the second seat body 15 . For example, the sound insulation pad may be sound insulation cotton, thereby preventing abnormal noise from occurring between the cover body 16 and the second seat body 15 .

[0104] According to some embodiments of the present invention, the second locking mechanism 30 is an integrally formed metal part, so that the second locking mechanism 30 can be easily formed, and the number of parts of the second locking mechanism 30 can be reduced, which has the effect of reducing costs.

[0105] According to some embodiments of the present invention, Figure 4 As shown, the first locking mechanism 20 is provided with a first locking groove 21 , the second locking mechanism 30 locks the first locking mechanism 20 by extending into the first locking groove 21 , and the second locking mechanism unlocks the first locking mechanism 20 by disengaging from the first locking groove 21 .

[0106] The first locking mechanism 20 is provided with a first locking groove 21, and the rod portion 32 of the second locking mechanism 30 extends into the first locking groove 21 for limited fit, so that the second locking mechanism 30 can be locked with the first locking mechanism 20. When the rod portion 32 of the second locking mechanism 30 is separated from the first locking groove 21, the second locking mechanism 30 can be unlocked from the first locking mechanism 20.

[0107] Specifically, when the base assembly 100 is in the retracted state, the angle formed by the gravity direction of the second locking mechanism 30 and the direction of the sliding hole 12 away from the first locking mechanism 20 is a stop angle. The head 31 of the second locking mechanism 30 is on the top and the rod 32 is on the bottom. Due to the action of gravity, the second locking mechanism 30 slides along the sliding hole 12 toward the first locking mechanism 20 until the head 31 of the second locking mechanism 30 is limitedly engaged with the inclined plate portion 153. At this time, the rod 32 of the second locking mechanism 30 is pressed on the first locking groove 21, thereby preventing the first locking mechanism 20 from rotating, so that the cup holder assembly 40 is always in a locked state.

[0108] When the base assembly 100 is in the process of being laid down, the angle formed by the gravity direction of the second locking mechanism 30 and the direction of the sliding hole 12 away from the first locking mechanism 20 gradually decreases from an obtuse angle. At this time, the component force of the gravity direction of the second locking mechanism 30 in the sliding hole 12 is greater than the friction force between the rod 32 and the sliding hole 12, so that the second locking mechanism 30 begins to slide toward the cover body 16, and the rod 32 of the second locking mechanism 30 gradually disengages from the first locking groove 21, so that the cup holder assembly 40 can be gradually unlocked.

[0109] When the base 10 assembly is in a laid-down state, the angle formed by the gravity direction of the second locking mechanism 30 and the direction of the sliding hole 12 away from the first locking mechanism 20 is reduced to an acute angle, the rod 32 of the second locking mechanism 30 is on the top, and the head 31 is on the bottom. The second locking mechanism 30 slides along the sliding hole 12 toward the cover body 16 under the action of gravity until the head 31 is pressed against the inner wall of the cover body 16. At this time, the rod 32 of the second locking mechanism 30 is completely disengaged from the first locking groove 21, and the first locking mechanism 20 can be rotated, thereby realizing the unlocking of the cup holder assembly 40.

[0110] According to some embodiments of the present invention, Figure 5 As shown, the first locking groove 21 has at least three stop surfaces 22 adjacent to each other, which are used for abutting and cooperating with the second locking mechanism 30 .

[0111] The provision of at least three stop surfaces 22 can limit the rod portion 32 of the second locking mechanism 30 in different directions, thereby playing a role in fixing the rod portion 32 of the second locking mechanism 30 .

[0112] According to some embodiments of the present invention, Figure 5 As shown, a guiding slope 23 is provided at the notch of the first locking groove 21 , and the guiding slope 23 is used to guide the second locking mechanism 30 to enter the first locking groove 21 .

[0113] The setting of the guiding inclined surface 23 can play a guiding role, so that the rod portion 32 of the second locking mechanism 30 can be easily inserted into the first locking groove 21 and stop-fit ​​with the stop surface 22 .

[0114] According to some embodiments of the present invention, Figure 2 As shown, the first locking mechanism 20 is provided with a second locking groove 24 , and the second locking groove 24 is used to lock with the locking portion 60 of the cup holder assembly 40 .

[0115] When the first locking mechanism 20 is disengaged from the second locking mechanism 30, the locking portion 60 is in a locked state in the second locking groove 24. When the cup holder assembly 40 is pressed by an external force, the locking portion 60 moves along the trajectory of the second locking groove 24, so that the locking portion 60 can gradually disengage from the second locking groove 24, thereby causing the cup holder assembly 40 to pop out.

[0116] According to some embodiments of the present invention, Figure 7 As shown, the second locking groove 24 includes: an entry groove section 241, an exit groove section 242 and a locking groove section 243. The locking groove section 243 is connected to the entry groove section 241 and the exit groove section 242. A portion of the locking groove section 243 is bent to form a locking point for locking with the locking portion 60.

[0117] The locking portion 60 may be a pin shaft. When the cup holder assembly 40 is pressed to open, the locking portion 60 gradually slides from the locking groove section 243 to the exit groove section 242, which can force the first locking mechanism 20 to rotate toward the second locking mechanism 30 until the locking portion 60 is disengaged from the exit groove section 242, thereby enabling the cup holder assembly 40 to be ejected.

[0118] In addition, a portion of the locking groove section 243 is bent to form a locking point for locking with the locking portion 60 , so that the locking portion 60 and the locking groove section 243 can be limitedly matched to prevent the locking portion 60 from moving.

[0119] According to some embodiments of the present invention, Figure 8 As shown, the side wall of the slot entry section 241 adjacent to the slot exit section 242 is configured as a guide arc surface 2411 for guiding the locking portion 60 of the cup holder assembly 40 to enter the second locking slot 24 from the slot entry section 241 .

[0120] Among them, when the locking portion 60 is separated from the exit groove section 242, since the side wall of the entry groove section 241 adjacent to the exit groove section 242 is the guiding arc surface 2411, the guiding arc surface 2411 can block and guide the locking portion 60, and the locking portion 60 can slide along the guiding arc surface 2411. At this time, the cup holder assembly 40 is in a pop-up state.

[0121] According to some embodiments of the present invention, Figure 6 and Figure 8 As shown, the groove section 242 includes: a first groove section 2421 and a second groove section 2422. The depth of the first groove section 2421 is the same at all locations along its length direction. The first groove section 2421 is connected between the locking groove section 243 and the second groove section 2422. The depth of the second groove section 2422 decreases in the direction away from the first groove section 2421.

[0122] Among them, the depth of the first groove section 2421 is the same at all places along its length direction, which can ensure the stability of the locking part 60 during the sliding process and prevent the locking part 60 from separating from the first groove section 2421. The depth of the second groove section 2422 decreases in the direction away from the first groove section 2421, so that the second groove section 2422 can easily push the locking part 60 out of the second groove section 2422.

[0123] Specifically, when the cup holder assembly 40 is pressed to open, the first locking mechanism 20 can be forced to rotate toward the second locking mechanism 30, and the locking portion 60 gradually slides from the locking groove section 243 to the first groove section 2421. After reaching the first groove section 2421, the locking portion 60 continues to slide toward the second groove section 2422, and continues to apply a pulling force to the cup holder assembly 40, driving the locking portion 60 to move and press the second groove section 2422 downward, and then disengage from the second groove section 2422, thereby unlocking the cup holder assembly 40.

[0124] According to some embodiments of the present invention, Figure 6 As shown, the base assembly 100 of the armrest further includes: an elastic member 50, which abuts between the first locking mechanism 20 and the base 10. After the locking portion 60 of the cup holder assembly 40 slides out of the second locking groove 24 from the groove section 242, the elastic member 50 pushes the first locking mechanism 20 in a direction away from the base 10, thereby preventing the locking portion 60 of the cup holder assembly 40 from entering the second locking groove 24 from the groove section 242.

[0125] Among them, when the locking portion 60 slides in the second groove section 2422, since the depth of the second groove section 2422 decreases in the direction away from the first groove section 2421, the locking portion 60 generates downward pressure on the second groove section 2422. Since the elastic member 50 is located between the first locking mechanism 20 and the base 10, the second groove section 2422 compresses the elastic member 50 to deform downward. When the locking portion 60 slides out of the second groove section 2422, the pressure on the elastic member 50 by the locking portion 60 disappears, the elastic member 50 restores its elastic deformation, and the second groove section 2422 rebounds to the initial position under the elastic driving force of the elastic member 50. At this time, the cup holder assembly 40 is in use, and the locking portion 60 of the cup holder assembly 40 can also be prevented from entering the second locking groove 24 from the groove section 242.

[0126] When the cup holder assembly 40 is closed, the locking portion 60 slides along the guiding arc surface 2411, and can force the first locking mechanism 20 to rotate in a direction away from the second locking mechanism 30, until the locking portion 60 enters the entry groove section 241, and then slides to the rounded position of the locking groove section 243. At this time, the pulling force applied to the cup holder assembly 40 is canceled, so that the cup holder assembly 40 can be re-locked.

[0127] According to some embodiments of the present invention, Figure 2 and Figure 5 As shown, the base 10 is provided with a rotating shaft 17, the first locking mechanism 20 is provided with a rotating hole 25, the rotating shaft 17 passes through the rotating hole 25, and the length of the rotating shaft 17 is greater than the depth of the rotating hole 25, and the elastic member 50 is a spring sleeved on the rotating shaft 17.

[0128] Among them, the rotating hole 25 of the first locking mechanism 20 is penetrated on the rotating shaft 17 of the base 10, so that the first locking mechanism 20 can rotate around the rotating shaft 17, and the length of the rotating shaft 17 is greater than the depth of the rotating hole 25, which can provide installation space for the spring, thereby facilitating the movement of the spring in the installation space.

[0129] According to some embodiments of the present invention, Figure 6 As shown, the first locking mechanism 20 is provided with a reinforcing rib 26 , the reinforcing rib 26 is arranged around the rotating hole 25 , and the elastic member 50 abuts against the reinforcing rib 26 .

[0130] Among them, the elastic member 50 is assembled between the reinforcing rib 26 and the base 10, which can increase the strength at the rotating hole 25. The fastener presses the annular reinforcing rib 26 against the elastic member 50 and fixes it on the rotating shaft 17 of the base 10, so that the first locking mechanism 20 can rotate around the rotating shaft 17. At the same time, the elastic driving force of the elastic member 50 can make the first locking mechanism 20 move axially along the rotating shaft 17.

[0131] According to some embodiments of the present invention, Fig.13 As shown, the base 10 is provided with a second boss 27 , and the rotating shaft 17 is provided on the second boss 27 .

[0132] The base 10 is provided with a second boss 27 protruding upward, which can provide a mounting position for the first locking mechanism 20 and ensure that the first locking mechanism 20 is more stable during rotation. In addition, the rotating shaft 17 is provided on the second boss 27, which can provide a mounting position for the rotating shaft 17, thereby improving the strength of the rotating shaft 17.

[0133] According to some embodiments of the present invention, Figure 2 As shown, the base 10 is provided with a first limiting portion 28 and a second limiting portion 29 on opposite sides of the first locking mechanism 20 , respectively, for limiting the rotation range of the first locking mechanism 20 .

[0134] In the process of the locking portion 60 sliding from the locking groove section 243 to the exit groove section 242 and then coming out of the exit groove section 242, the first locking mechanism 20 rotates to a position where it contacts the first limiting portion 28 and stops. When sliding from the entry groove section 241 to the locking groove section 243, the first locking mechanism 20 rotates to a position where it contacts the second limiting portion 29 and stops. In this way, the rotation angle of the first locking mechanism 20 can be reasonably limited, so that the angle is not too large and exceeds the boundary, resulting in the locking portion 60 being unable to be pushed into the second locking groove 24.

[0135] The armrest according to the embodiment of the second aspect of the utility model comprises: the base assembly 100 of the armrest of the above embodiment and the cup holder assembly 40 , and the cup holder assembly 40 can be telescopically disposed in the receiving groove 11 .

[0136] When the cup holder assembly 40 is in use, the cup holder assembly 40 can be pulled out of the receiving groove 11 , and when the cup holder assembly 40 is not in use, the cup holder assembly 40 is pushed into the receiving groove 11 , which can not only save space but also play a protective role.

[0137] The seat according to the embodiment of the third aspect of the utility model comprises: a backrest and the armrest of the above embodiment, and the armrest is rotatably arranged on the backrest.

[0138] The armrests at the backrest can be folded up and laid down, making it easier for passengers to use.

[0139] A vehicle according to an embodiment of the fourth aspect of the utility model comprises: the seat of the above embodiment.
