[0034] The preferred embodiments of the present application will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application, and are not intended to limit the protection scope of the present application.

[0035] It should be noted that in the description of the present application, the terms "inner", "outer", "upper", "top" and the like indicate the direction or positional relationship shown in the drawings, which is only for the convenience of description, and does not indicate or imply that the device or element must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation of the present application. In addition, the terms "first", "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance.

[0036] In addition, it should also be noted that in the description of the present application, unless otherwise specified and limited, the terms "set", "connected", "installed" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrally connected. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0037] The existing telescopic cup holder of the seat armrest as indicated in the background art will occupy the lateral space of the seat after being unfolded, and is likely to interfere with the adjacent seat armrest or affect the entry and exit of the passenger. The utility model provides a seat armrest of a vehicle, a seat of a vehicle and a vehicle, which aims to set a first linkage groove and a second linkage groove on a first claw and a second claw arranged at intervals respectively, set a linkage sliding groove on the cup holder at a position between the first claw and the second claw and close to the first claw, and simultaneously connect the first claw, the second claw and the linkage sliding groove through a linkage pin shaft, so as to realize the linkage of the first claw and the second claw, and make the first claw and the second claw deviate to the inner side of the seat after being unfolded, thereby reducing the occupation of the first claw and the second claw to the lateral space of the seat after being unfolded.

[0038] At present, many vehicle models (such as SUV or MPV) are provided with two independent seats arranged in the middle row to form a passageway between the two seats, which not only improves the comfort of the seat, but also facilitates the entry and exit of the passengers in the rear row. Meanwhile, in order to further enrich the functions of the seat, a seat armrest is arranged on one side or both sides of the seat, and a telescopic cup holder is integrated on the seat armrest, so that the passenger can flexibly unfold or fold the cup holder according to the need, thereby improving the flexibility of use and the space utilization.

[0039] The telescopic cup holder usually adopts a form of front and rear telescoping and lateral unfolding, that is, the cup holder can slide out of the armrest forwardly, and the cup holder installed on the cup holder can be unfolded to both sides after sliding out of the shell, so as to clamp and fix the cup.

[0040] However, after the cup holder is unfolded laterally, the lateral space of the seat will be inevitably occupied, for example, when the seat slides laterally, the cup holder installed on the side close to the passageway is likely to interfere with or even collide with the cup holder of the adjacent seat, which greatly limits the lateral sliding space of the seat, so that the distance of the seat adjusted to the middle is limited, which not only affects the viewing angle of the passenger, but also affects the normal entry and exit of the passengers in the rear row, thereby causing great inconvenience to the passengers.

[0041] Based on the above reasons, the seat armrest of the utility model is installed on the side of the seat close to the passageway, as shown in the drawings, which comprises a shell 1. Figures 1 to 5 The shell 1 is installed on the side of the seat close to the passageway in a form of fixed connection or pivotal connection, the shell 1 is internally formed with an accommodating cavity, and the front end is provided with an opening 11 communicating the accommodating cavity with the external space.

[0042] A cup holder 2 is installed in the shell 1, and the cup holder 2 and the inner wall of the shell 1 are both provided with a sliding mechanism matched with each other, such as a sliding block and a sliding rail mechanism, a guide wheel and a guide rail mechanism, etc., so that the cup holder 2 can slide forward and backward in the shell 1, thereby enabling the front part of the cup holder 2 to slide out of the shell 1 through the opening 11.

[0043] The cup holder is arranged in the mounting groove at the front of the cup seat 2, and comprises a first clamping jaw 31 and a second clamping jaw 32 arranged at intervals on the cup seat 2, wherein the first clamping jaw 31 is hinged on the side close to the seat and comprises a first clamping portion 311, a first hinge portion 312 and a first linkage portion 313 arranged in sequence from front to back; the second clamping jaw 32 is hinged on the side away from the seat (i.e. the side close to the middle aisle), and comprises a second clamping portion 321, a second hinge portion 322 and a second linkage portion 323 arranged in sequence from front to back; the first clamping jaw 31 and the second clamping jaw 32 are pivotally connected to the cup seat 2 through the first hinge portion 312 and the second hinge portion 322 respectively, so as to realize the free rotation of the first clamping jaw 31 and the second clamping jaw 32.

[0044] By driving the first clamping jaw 31 and the second clamping jaw 32 to rotate to both sides, the first clamping portion 311 and the second clamping portion 321 can be unfolded to both sides to form a clamping space between the first clamping portion 311 and the second clamping portion 321, thereby realizing the clamping and fixing of the cup.

[0045] When the cup holder needs to be used, as shown in Figure 1 , only the cup seat 2 needs to be controlled to slide out forward to expose the cup holder to the shell 1, while the first clamping jaw 31 and the second clamping jaw 32 are unfolded to the outside respectively; when the cup holder does not need to be used, as shown in Figure 3 , only the first clamping jaw 31 and the second clamping jaw 32 need to be folded to the inside respectively, and then the cup seat 2 is controlled to slide back to the shell 1 to retract the cup holder.

[0046] In actual application, the sliding of the cup seat 2 relative to the shell 1 can be driven by manual pushing and pulling of the user, or by installing a driving device such as a driving motor, a driving spring, etc., and the preferred embodiment of the present application adopts a driving spring, the two ends of which are connected to the cup seat 2 and the shell 1 respectively, and specifically, a locking mechanism is further arranged between the cup seat 2 and the shell 1, which can lock the cup seat 2 in the shell 1; when the cup seat 2 is in the locked state, the driving spring is compressed to accumulate elastic potential energy; when the locking mechanism is unlocked, the driving spring releases the elastic potential energy to push the cup seat 2 out of the shell 1, thereby realizing the automatic sliding of the cup seat 2 and improving the use quality and convenience of the cup seat 2. The driving spring can be flexibly arranged as a tensile spring, a compression spring or a torsional spring, etc., which is not limited in the present case.

[0047] In order to enable the first clamping jaw 31 and the second clamping jaw 32 to rotate synchronously, simplify the unfolding process and fix the unfolding distance, as shown in Figure 2 , Figure 4 and Figure 5As shown, the first connecting groove 314 is arranged on the first connecting part 313 and extends along the length direction of the first clamping jaw 31; correspondingly, the second connecting groove 324 is arranged on the second connecting part 323 and extends along the length direction of the second clamping jaw 32. The connecting sliding groove 21 is arranged on the cup holder 2 between the first clamping jaw 31 and the second clamping jaw 32 and extends along the sliding direction of the cup holder 2, wherein the connecting sliding groove 21 is closer to the first clamping jaw 31, i.e. the distance between the connecting sliding groove 21 and the first clamping jaw 31 is smaller than the distance between the connecting sliding groove 21 and the second clamping jaw 32. The connecting pin 4 is connected with the first connecting groove 314, the second connecting groove 324 and the connecting sliding groove 21, so that when any one of the first clamping jaw 31, the second clamping jaw 32 and the connecting pin 4 moves, the other two components can move synchronously, realizing the connection of the three components.

[0048] Specifically, in the present scheme, when the cup holder is unfolded, as shown in Figure 1 and Figure 2 , the first clamping part 311 and the second clamping part 321 move outward, the first connecting part 313 and the second connecting part 323 move inward, driving the connecting pin 4 to slide along the connecting sliding groove 21 from back to front; when the cup holder is folded, as shown in Figure 3 and Figure 4 , the first clamping part 311 and the second clamping part 321 move inward, the first connecting part 313 and the second connecting part 323 move outward, driving the connecting pin 4 to slide along the connecting sliding groove 21 from front to back. Therefore, applying driving force to at least one of the first clamping jaw 31, the second clamping jaw 32 and the connecting pin 4 can make the three components move synchronously, realizing the stable unfolding and folding of the cup holder.

[0049] In order to realize the automatic unfolding and folding of the cup holder, the driving assembly is further arranged in the seat armrest of the present application and is drivingly connected with at least one of the first clamping jaw 31, the second clamping jaw 32 and the connecting pin, so as to realize the automatic unfolding of the first clamping jaw 31 and the second clamping jaw 32, improving the convenience of use.

[0050] It should be noted that in actual application, the driving assembly can be flexibly arranged as a torsional spring, a driving motor or a pneumatic cylinder, etc. as long as it can drive the first clamping jaw 31 and the second clamping jaw 32 to unfold outwardly. Such flexible adjustment and change do not deviate from the principles and scope of the present application and should be limited within the protection scope of the present application.

[0051] Preferably, as shown in Figure 2 , Figure 4 and Figure 5As shown, in the scheme, the driving assembly is arranged as a torsion spring, is also arranged in the mounting groove, and the number of the torsion spring is further preferably two, including a first torsion spring 51 and a second torsion spring 52, the fixed ends of the two torsion springs are fixedly connected with the cup seat 2, and the torsion ends of the two torsion springs are fixedly connected with the first clamping jaw 31 and the second clamping jaw 32 respectively. By synchronously deforming, synchronously storing energy and synchronously resetting the two torsion springs, torsion can be synchronously applied to the first clamping jaw 31 and the second clamping jaw 32, so that balanced stress of the first clamping jaw 31 and the second clamping jaw 32 is ensured, and the stability when the two are unfolded is improved.

[0052] As shown in the drawings, Figure 5 The top of the mounting groove is also provided with a detachable fixed cover plate 22, which can cover the first connecting part 313, the second connecting part 323, the torsion spring and the connecting shaft pin, on the one hand, the internal components of the first connecting part 313, the second connecting part 323, the torsion spring and the connecting shaft pin are prevented from being exposed after the cup seat 2 slides out of the shell 1, interference with the arms of passengers is avoided, and the appearance and safety of the cup seat 2 are improved; on the other hand, the internal components are convenient for quick maintenance and disassembly.

[0053] In addition, as shown in the drawings, Figure 1 , Figure 2 , Figure 4 and Figure 5 In a preferred embodiment of the scheme, the cup seat 2 is also provided with a limiting structure 23, which is arranged between the first clamping part 311 and the second clamping part 321 after unfolding, and is preferably a limiting groove. The shape and size of the limiting groove can be flexibly set according to the cup, and the limiting groove is used in cooperation with the first clamping jaw 31 and the second clamping jaw 32, so that the cup can be clamped and fixed in multiple directions, and the stability of the cup is further improved.

[0054] In addition, the seat provided on the basis of the seat armrest of the utility model, and the seat armrest is installed on one side of the seat close to the middle aisle of the vehicle, and thus has the technical effects of the seat armrest.
