It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

In addition, the terms "first", "second", "third", "fourth", "fifth" and "sixth" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0037] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "set", "install", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] Based on the problem pointed out in the background technology that the existing seat armrests cannot adjust the length and angle at the same time, which affects the convenience of adjustment and the comfort of riding. The present invention provides an armrest device for a seat, a seat, and a vehicle, which aims to achieve the length and angle adjustment of the armrest device and the locking and unlocking control at different angles by setting the armrest device as a first shell and a second shell that are slidably connected, and installing a first connecting rod assembly and a second connecting rod assembly in the first shell and the second shell respectively, so that the first connecting rod assembly and the second connecting rod assembly are slidably connected, and the driving force of the switch assembly can be transmitted to the locking member.

[0039] Specifically, Figures 1 to 6 As shown, the armrest device of the present invention includes: a first shell 1, which is pivotally connected to the backrest of the seat; a locking member 3, which is installed between the first shell 1 and the backrest and can rotate between a locking position and an unlocking position to achieve locking and unlocking between the first shell 1 and the backrest; a second shell 2, which is slidably connected to the first shell 1 and can slide along the length direction of the first shell 1; a first connecting rod assembly, which is installed on the first shell 1, and the first end of the first connecting rod assembly is drivingly connected to the locking member 3, and can rotate synchronously with the locking member 3; a second connecting rod assembly, which is installed on the second shell 2, and the first end of the second connecting rod assembly is slidably connected to the second end of the first connecting rod assembly to move with the second shell 2; a switch assembly 5, which is installed on the second shell 2, and the switch assembly 5 is drivingly connected to the second end of the second connecting rod assembly, and can drive the second connecting rod assembly and the first connecting rod assembly to move, thereby driving the locking member 3 to rotate between the locking position and the unlocking position.

[0040] For example, the armrest device of the present invention is usually installed on the middle row seats of SUV or MPV models, specifically on the side of the seat back. It can be selected to install one on only one side of the seat (usually the side close to the middle aisle of the vehicle), or one on each side of the seat. It can provide strong support for the passenger's forearm, relieve forearm fatigue, and improve riding comfort.

[0041] Specifically, the first shell 1 is pivotally connected to the side of the backrest and can rotate around the pivot point in a vertical plane to adjust the elevation angle of the armrest device. The second shell 2 covers the upper part of the first shell 1, and a cavity structure is formed inside the two to accommodate and install transmission connecting rods, switch components 5 and other mechanisms. A sliding structure extending along the length direction of the armrest device is provided at the position where the second shell 2 is connected to the first shell 1, so that the second shell 2 can slide relative to the first shell 1 to achieve length adjustment of the armrest device to accommodate passengers with different arm lengths.

[0042] In order to be able to lock and unlock the armrest device at different elevation positions and facilitate user operation, the switch assembly 5 is arranged at the front end of the second shell 2, the first connecting rod assembly is installed in the first shell 1, and the second connecting rod assembly is installed in the second shell 2, so that the second connecting rod assembly can also slide relative to the first connecting rod assembly along the length direction of the armrest device so as to be synchronously extended and retracted with the second shell 2. The first connecting rod assembly is fixedly connected to the locking member 3, and the second connecting rod assembly is drivingly connected to the switch assembly 5. The driving force applied by the user to the switch assembly 5 can be transmitted to the locking member 3 through the first connecting rod assembly and the second connecting rod assembly, so that the locking member 3 rotates, thereby realizing the locking and unlocking of the armrest device.

[0043] Through such an arrangement, on the one hand, independent adjustment of the angle and length of the armrest device is achieved, and the adjustable range and stroke are increased, so that it can adapt to the angle adjustment of the seat back and meet the needs of users of different body shapes and sitting postures; on the other hand, the locking and unlocking of the armrest device at any angle is achieved, so that the armrest device can be directly adjusted in both directions from any angle. Compared with the existing solution of using a ratchet and pawl mechanism to lock and unlock the armrest device, the present invention does not need to rotate the armrest device to the highest point before unlocking it, thereby improving the adjustment efficiency; on the other hand, the space occupied when folded is small, thereby reducing the occupation of the lateral space of the seat.

[0044] Preferably, if Figure 5 and Figure 6 As shown, the first link assembly of the present invention includes: a first link 41, a first end of the first link 41 is pivotally connected to the first housing 1 and fixedly connected to the locking member 3; a second link 42, a first end of the second link 42 is pivotally connected to the second end of the first link 41; a third link 43, a first end of the third link 43 is pivotally connected to the second end of the second link 42, and the second end of the third link 43 is pivotally connected to the first housing 1; the second link assembly includes: a fourth link 44, a first end of the fourth link 44 is pivotally connected to the second housing 2; a fifth link 45, a first end of the fifth link 45 is pivotally connected to the second end of the fourth link 44; a sixth link 46, the sixth link 46 is pivotally connected to the second housing 2, a first end of the sixth link 46 is pivotally connected to the second end of the fifth link 45, and the second end of the sixth link 46 is drivingly connected to the switch assembly 5; the second link 42 and / or the third link 43 are slidably connected to the fifth link 45.

[0045] Exemplarily, when the user does not apply a driving force to the switch assembly 5, the locking member 3 is in the locked position. At this time, the armrest device is in a locked state and cannot be pressed or lifted. When the user applies a driving force to the switch assembly 5, the sixth link 46 will be driven to rotate clockwise around the pivot point between it and the second shell 2. During the rotation process, the first end of the sixth link 46 will drive the second end of the fifth link 45 to move downward, and then drive the pin 421 between the second link 42 and the third link 43 to rotate counterclockwise around the pivot point between the third link 43 and the first shell 1 through the slide groove 451, thereby driving the second link 42 to move backward, and then driving the first link 41 to rotate counterclockwise, thereby achieving the effect of driving the locking member 3 to rotate. At this time, the locking member 3 will rotate from the locked position to the unlocked position, releasing the lock between the armrest device and the backrest, allowing the armrest device to rotate freely, and realizing arbitrary adjustment of the elevation angle.

[0046] When the user adjusts the armrest device to a suitable elevation angle, the locking member 3 will automatically return to the locking position by simply removing the external force, thereby completing the locking of the armrest device and the seat back.

[0047] Therefore, through the sliding connection between the first link assembly and the second link assembly, the synchronous extension and retraction of the transmission link and the armrest device are met; at the same time, it is ensured that the armrest device can transmit the driving force to the locking member 3 through the switch assembly 5 in any extension and retraction position, so as to realize the locking and unlocking of the armrest device at different angles; in addition, the connecting rod mechanism is simple and reliable, and the mechanical properties are stable, which ensures the efficient transmission of the driving force and helps to reduce the failure rate.

[0048] Preferably, if Figure 5 and Figure 6 As shown, a slide groove 451 is provided on the fifth connecting rod 45 of the present invention, and the second end of the second connecting rod 42 is pivotally connected to the first end of the third connecting rod 43 through a pin shaft 421 , and the pin shaft 421 is installed in the slide groove 451 and can slide in the slide groove 451 .

[0049] The pin 421 is inserted into the slide groove 451 and can slide along the slide groove 451, which not only realizes the relative sliding of the first connecting rod assembly and the second connecting rod assembly, but also helps to simplify the connecting rod structure. It should be noted that in practical applications, those skilled in the art can flexibly set a variety of sliding structures, as long as the sliding connection between the first connecting rod assembly and the second connecting rod assembly can be realized, and this case is not specifically limited here.

[0050] Preferably, if Figures 1 to 6As shown, the switch assembly 5 of the present invention includes a driving member 51 slidably connected to the second housing 2, the driving member 51 includes a driving end and a transmission end, the driving end is located outside the second housing 2, the transmission end is located inside the second housing 2 and is drivingly connected to the second end of the sixth connecting rod 46, the driving member 51 can slide between the reference position and the driving position, and can drive the sixth connecting rod 46 to rotate, so as to drive the locking member 3 to synchronously rotate to the locking position and the unlocking position through the first connecting rod assembly and the second connecting rod assembly.

[0051] Exemplarily, in this scheme, an opening is provided at the bottom of the front end of the second shell 2, and the driving member 51 is passed through the opening from the bottom of the second shell 2, so that the driving end is exposed outside the opening, and the transmission end extends into the opening and is connected to the second end of the sixth connecting rod 46. The driving member 51 can slide up and down in the opening, and its sliding direction is preferably perpendicular to the length direction of the armrest device. In this case, the lower stop point of the driving member 51 is the reference position, and the upper stop point of the driving member 51 is the driving position. When the user applies pressing pressure to the driving end, the driving member 51 will move from the reference position to the driving position, and then push up the second end of the sixth connecting rod 46, so that the sixth connecting rod 46 rotates around the hinge point between it and the second shell 2, and finally drives the locking member 3 to rotate.

[0052] The locking member 3 is driven by pressing the switch assembly 5, so that the user can unlock the armrest device by pressing. On the one hand, it simplifies the structure and unlocking method of the switch assembly 5, making it easier for the user to operate; on the other hand, it is conducive to increasing the movement of the first transmission assembly and the second transmission assembly so as to drive the locking member 3 to rotate.

[0053] Preferably, if Figure 5 and Figure 6 As shown, the switch assembly 5 of the present invention further includes a return spring 52 , through which the drive member 51 is elastically connected to the second housing 2 , and the return spring 52 can apply elastic force to the drive member 51 to keep the drive member 51 at the reference position.

[0054] Exemplarily, the return spring 52 is sleeved on the driving member 51, one end of which is connected to the driving member 51, and the other end is connected to the second shell 2. When the user presses to unlock, the driving member 51 will move from the reference position to the driving position and compress the return spring 52. When the user removes the pressing force, the driving member 51 will return to the reference position from the driving position under the action of the return spring 52. Therefore, when the armrest device is in a locked state, the driving end of the switch assembly 5 is always exposed outside the second shell 2, which is convenient for the user to press from the outside.

[0055] Preferably, the armrest device of the present invention further comprises a return torsion spring (not shown in the figure), which is installed at the hinge between the sixth connecting rod 46 and the second shell 2 and can apply a torsional force to the sixth connecting rod 46 to keep the locking member 3 in the locked position.

[0056] Specifically, when the user presses to unlock, during the process of the driving member 51 moving from the reference position to the driving position, the sixth connecting rod 46 will be synchronously driven to rotate counterclockwise until the locking member 3 reaches the unlocking position, and at the same time, the return torsion spring will store a certain elastic potential energy; and when the user removes the pressing force, the return torsion spring releases the elastic potential energy, and at the same time applies a torsional force to the sixth connecting rod 46, causing the sixth connecting rod 46 to rotate counterclockwise until the locking member 3 reaches the locking position.

[0057] Preferably, if Figure 3 and Figure 4 As shown, the first housing 1 of the present invention is provided with a first slide rail 11 , and the second housing 2 is provided with a second slide rail 21 , and the first slide rail 11 and the second slide rail 21 are slidably matched.

[0058] Through the sliding cooperation between the first slide rail 11 and the second slide rail 21 , the sliding of the first housing 1 relative to the second housing 2 can be limited and guided, thereby ensuring the stability of the two when sliding relative to each other.

[0059] Preferably, if Figure 4 As shown, the first two ends of the first slide rail 11 of the present invention are further provided with a first damping member 111 and a second damping member 112 , respectively. The first damping member 111 and the second damping member 112 can limit the second slide rail 21 .

[0060] Exemplarily, the first damping member 111 and the second damping member 112 may be configured as elastic members, etc. In this case, the first damping member 111 and the second damping member 112 are both constructed of elastic sheets, including elastic parts on both sides and a limiting part between the two elastic parts.

[0061] The first damping member 111 and the second damping member 112 can limit the extreme positions of the second shell 2 at both ends, so that the first shell 1 can slow down in advance until it stops when approaching the extreme positions at both ends, thereby reducing the impact of the first shell 1 on the second shell 2.

[0062] Regarding the locking component, it is preferably configured as a recliner for adjusting the seat back angle. Since it is a conventional technical means in the field, it will not be elaborated in this case.

[0063] Preferably, if Figure 1 As shown, in order to further increase the comfort of the armrest device for arm support, the armrest device also includes a mask 6 wrapped on the second shell 2, and the mask 6 can be filled with soft materials such as sponge.

[0064] In addition, the seat further provided by the present invention on the basis of the above-mentioned armrest device has the technical effects possessed by the above-mentioned armrest device due to the adoption of the above-mentioned armrest device. Compared with the seat before the improvement, the seat of the present invention can arbitrarily adjust and lock the angle and length of the armrest in two directions at different angles, thereby improving the comfort of the seat and the convenience of adjustment, and improving the space utilization rate in the vehicle.

[0065] Finally, the vehicle further provided by the present invention on the basis of the above-mentioned seats has the technical effects possessed by the above-mentioned seats due to the adoption of the above-mentioned seats.
