Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of automobile seats, and particularly relates to a rear seat with an angle self-adapting adjusting armrest structure and an automobile. BACKGROUND

[0002] With the development of the automobile industry, the automobile penetration rate is getting higher and higher, and the market pays more and more attention to the ride comfort of automobiles, and various comfort configurations emerge as the times require. The rear backrest angle adjustment has also become one of the important comfort configurations of many vehicle models.

[0003] The rear backrest angle adjustment enables the rear seat to support the needs of various different groups of people or different needs of the same person. However, when the backrest angle is adjustable, a problem arises that the armrest in the middle of the rear seat is fixed to the backrest, and when the backrest angle is adjusted, the angle and height of the armrest supporting surface will change with the change of the backrest angle, while the door panel armrest that matches it will not change, resulting in the inability to provide the same armrest comfort experience to the passengers.

[0004] Chinese invention patent (application number: CN201810896963.2) discloses a hinge seat structure for angle self-adapting adjustment of an armrest, a seat structure and an automobile, which utilizes a lock hook to hook the rear pipe of the armrest, cooperates with a spring, and realizes that the backrest remains in a horizontal state when the main backrest is folded backward.

[0005] That is, the cooperation of the lock hook, the spring, the arc-shaped hole and the rear pipe of the armrest realizes the turnover limiting of the armrest framework, so that the position of the armrest framework is not affected when the backrest framework is turned over.

[0006] However, in the above patent, only when the backrest framework is in a specific position, the position of the lock hook can coincide with the arc-shaped hole, and then in the subsequent turnover process, the rear pipe of the armrest enters the lock hook, and when the backrest framework is in other positions, the position of the lock hook will be misaligned with the arc-shaped hole, so that the rear pipe of the armrest cannot smoothly enter the lock hook during the sliding process along the arc-shaped hole, and then the normal use is affected, and the use has great limitations. SUMMARY

[0007] The purpose of the present application is to provide a rear seat with an angle self-adapting adjusting armrest structure and an automobile, which solves the problem that the existing seat structure has no requirement for the inclination angle of the backrest assembly when the armrest assembly is converted from the backrest state to the armrest state, and is more convenient to use.

[0008] A rear seat with an angle self-adapting adjusting armrest structure, comprising:

[0009] a seat cushion assembly mounted on a vehicle body;

[0010] The backrest assembly comprises a backrest rotation shaft, and the backrest assembly is hinged to the vehicle body via the backrest rotation shaft;

[0011] The armrest assembly comprises an armrest rotation shaft, and the armrest assembly is hinged to the backrest assembly via the armrest rotation shaft, and the armrest rotation shaft is located above the backrest rotation shaft;

[0012] When the armrest assembly is rotated to be flat around the armrest rotation shaft, the cushion assembly supports the armrest assembly.

[0013] Further limited, the armrest assembly comprises an armrest support structure, when the armrest assembly is rotated to be flat around the armrest rotation shaft, the cushion assembly supports the armrest assembly via the armrest support structure.

[0014] Such a structure design, through the setting of the armrest support structure, makes the cushion assembly support the armrest assembly via the armrest support structure, can raise the height of the upper end surface of the armrest assembly after being rotated to be flat without changing the overall thickness of the armrest assembly, improves the comfort of the passenger, and has strong practicability.

[0015] Further limited, the armrest support structure is a headrest installed on the upper part of the armrest assembly.

[0016] Such a structure design, through the headrest as the armrest support structure, when the armrest assembly is used as a backrest, the armrest support structure can be used as a headrest to support the head of the passenger leaning against the armrest assembly, improves the comfort of the passenger, and has strong practicability.

[0017] Further limited, the headrest is provided with a convex feature on both sides.

[0018] Such a structure design, through the setting of the convex feature, can raise the height of the upper end surface of the armrest assembly after being rotated to be flat without changing the overall thickness of the headrest, improves the comfort of the passenger; at the same time, when the armrest assembly is used as a backrest, the head of the passenger can be supported on both sides, further improves the comfort of the passenger, and has strong practicability.

[0019] Further limited, the surface material of the armrest support structure and the cushion assembly is selected to be a mute material.

[0020] Such a structure design, through selecting the surface material of the armrest support structure and the cushion assembly to be a mute material such as mute leather, can avoid the problem of friction noise when the backrest assembly rotates to drive the armrest assembly to move relative to the cushion assembly, and then the friction between the armrest support structure and the cushion assembly occurs, and has strong practicability.

[0021] Further limited, the seat cushion assembly comprises a seat cushion support structure, when the armrest assembly is rotated to be flat around the armrest rotation shaft, the seat cushion assembly supports the armrest assembly through the seat cushion support structure.

[0022] The structure design makes the seat cushion assembly support the armrest assembly through the seat cushion support structure, which can raise the height of the upper end surface of the armrest assembly after being rotated to be flat without changing the overall thickness of the armrest assembly, improves the comfort of passengers, and has high practicability.

[0023] Further limited, the seat cushion assembly is provided with a containing groove at one end away from the backrest assembly, and the seat cushion support structure is hinged in the containing groove.

[0024] The structure design contains the seat cushion support structure through the containing groove, avoids the influence of the seat cushion support structure on the use of passengers when the armrest assembly is used as a backrest, and forms the support of the armrest assembly by rotating the seat cushion support structure from the containing groove to the upper side of the seat cushion assembly when the armrest assembly is used as a hand support of passengers.

[0025] Further limited, the backrest assembly comprises a backrest framework assembly and a backrest foam assembly.

[0026] The armrest assembly comprises an armrest framework assembly and an armrest foam assembly, and the backrest framework assembly is fixedly installed with an auxiliary foam assembly below the armrest foam assembly.

[0027] The structure design blocks the gap between the armrest assembly and the seat cushion assembly through the auxiliary foam assembly, improves the comfort of passengers when the armrest assembly is used as a backrest, and improves the appearance of the whole seat, which has high practicability.

[0028] Further limited, the backrest framework assembly is fixedly installed with an armrest support on the upper side, and the armrest support is in a U shape.

[0029] The armrest framework assembly is rotatably installed on the armrest support through the armrest rotation shaft.

[0030] The structure design, through the cooperation of the U-shaped handrail support and the handrail rotating shaft, realizes the rotating connection between the handrail assembly and the backrest assembly, increases the distance between the handrail rotating shaft and the backrest framework assembly, reduces the interference between the handrail foam assembly and the auxiliary foam assembly when the handrail assembly rotates, and has high practicability.

[0031] Further, the side surface of the handrail support is provided with an arc-shaped channel with the handrail rotating shaft as the center, and the side wall of the handrail framework assembly is provided with a handrail limiting shaft which is arranged in the arc-shaped channel.

[0032] The structure design limits the maximum rotating angle between the handrail assembly and the backrest assembly through the cooperation of the handrail limiting shaft and the arc-shaped channel, avoids excessive rotation of the handrail assembly, and has high practicability.

[0033] Further, the side wall of the handrail support is provided with a handrail support plate.

[0034] The edge of the handrail support plate is provided with an arc-shaped edge, and the side surface of the handrail limiting shaft abuts against the arc-shaped edge.

[0035] The structure design can strengthen the structural strength of the side wall of the handrail support, provide resistance to the rotation of the handrail assembly through the contact between the handrail limiting shaft and the arc-shaped edge, and avoid the problem of abnormal sound caused by the relative movement of the metal handrail limiting shaft and the metal handrail support. In addition, the handrail support plate can be directly replaced without replacing the handrail support when the contact part is worn out after long-term use, and has high practicability.

[0036] Further, the end portions of the arc-shaped edge of the handrail support plate are provided with arc-shaped features.

[0037] When the handrail assembly rotates to the maximum position relative to the backrest assembly, the handrail limiting shaft abuts against the arc-shaped features.

[0038] The structure design supports the handrail limiting shaft when it rotates to the maximum position instead of the handrail support, avoids the problem of abnormal sound caused by the collision between the handrail limiting shaft and the handrail support, and has high practicability.

[0039] Further, the arc-shaped channel is two and is arranged on the two sides of the handrail support.

[0040] The handrail support plates are two and are located on both sides of the handrail support frame.

[0041] The handrail rotating shafts are two and are located on both sides of the handrail assembly.

[0042] The structure design, through the setting of the two arc-shaped channels and the two handrail rotating shafts, makes both sides of the handrail assembly have limiting capacity when the handrail assembly rotates clockwise to the maximum position relative to the handrail support frame, and compared with the setting of the arc-shaped channel and the handrail rotating shaft on one side, the setting on both sides can reduce the possibility of the handrail assembly deviating from the backrest assembly when the handrail assembly rotates clockwise to the maximum position relative to the handrail support frame, and has high practicability.

[0043] Further limitation, the lower part of one side of the handrail support frame is provided with a first notch, and the first notch is communicated with one of the arc-shaped channels;

[0044] The lower part of the handrail support plate corresponding to the first notch is provided with a second notch.

[0045] The structure design, through the setting of the first notch and the second notch, destroys one of the arc-shaped channels and the arc-shaped edges, so that only one arc-shaped edge provides resistance to the rotation of the handrail assembly, reduces the assembly difficulty of the contact assembly between the handrail limiting shaft and the arc-shaped edge on the basis of retaining that both sides of the handrail assembly are limited when the handrail support frame rotates clockwise to the maximum position, and has high practicability.

[0046] Further limitation, the outer side of the handrail support frame is fixedly provided with a connecting arm at the position of the first notch, and the middle part of the connecting arm is warped outward.

[0047] The structure design, through the fixing of the connecting arm to both sides of the position of the first notch, strengthens the structural strength of the handrail support frame reduced due to the first notch, and through the warping of the middle part of the connecting arm, avoids the sliding of the handrail limiting shaft in the arc-shaped channel, and has high practicability.

[0048] Further limitation, the backrest assembly is further fixedly provided with a handrail back plate, both sides of the handrail back plate are provided with shielding plates, and the two shielding plates are located on the outer side of the handrail support frame.

[0049] The structure design, through the shielding plates on the handrail back plate, shields various structures on the side of the handrail support frame, avoids the problem of skeleton leakage, and has high practicability.

[0050] An automobile comprising the rear seat with the angle self-adaptive adjusting handrail structure.

[0051] The application adopting the above technical scheme has the following advantages:

[0052] 1. The hinge between the armrest assembly and the backrest assembly is completed by the armrest hinge shaft, and the rear end of the armrest assembly is supported by the armrest hinge shaft, and the seat cushion assembly supports the armrest assembly after the armrest assembly is rotated and flattened, thereby limiting the armrest assembly; at the same time, even after the armrest assembly is rotated and flattened, the backrest assembly continues to rotate around the backrest hinge shaft to change the angle between the backrest assembly and the seat cushion assembly, and the armrest assembly can automatically rotate around the armrest hinge shaft under the action of its own gravity and the supporting force of the seat cushion assembly, so that the armrest assembly remains substantially horizontal;

[0053] 2. Through such structural design and arrangement, the rear seat armrest angle self-adapting adjustment is realized without increasing additional structures, and the appearance quality of the folded state, the flattened state and the backrest adjustment state of the armrest is also considered, which has high practicability;

[0054] 3. Through the arrangement of the armrest support structure, the seat cushion assembly supports the armrest assembly through the armrest support structure, the height of the upper end surface of the armrest assembly after being rotated and flattened can be raised without changing the overall thickness of the armrest assembly, the comfort of the passenger is improved, and the practicability is high;

[0055] 4. Through the arrangement of the convex feature, the height of the upper end surface of the armrest assembly after being rotated and flattened can be raised without changing the overall thickness of the headrest, the comfort of the passenger is improved, and the practicability is high; at the same time, when the armrest assembly is used as a backrest, the head of the passenger can be supported on both sides, which further improves the comfort of the passenger, and the practicability is high;

[0056] 5. Through the arrangement of the seat cushion support structure, the seat cushion assembly supports the armrest assembly through the seat cushion support structure, the height of the upper end surface of the armrest assembly after being rotated and flattened can be raised without changing the overall thickness of the armrest assembly, the comfort of the passenger is improved, and the practicability is high;

[0057] 6. Through the cooperation of the armrest limiting shaft and the arc-shaped channel, the maximum rotation angle between the armrest assembly and the backrest assembly is limited, and excessive rotation of the armrest assembly is avoided, which has high practicability;

Through the arrangement of the armrest support plate, the structural strength of the armrest support side wall can be improved, and through the contact between the armrest limiting shaft and the arc-shaped edge, resistance to the rotation of the armrest assembly can be provided by the arc-shaped edge, so that the armrest assembly does not rotate too fast, which has high practicability; at the same time, when the armrest support plate is made of plastic or other materials, the problem of abnormal noise caused by the relative movement of the metal-made armrest limiting shaft and the metal-made armrest support after direct contact can be avoided, and when the contact part is worn after long-term use, the armrest support plate can be replaced directly without replacing the armrest support, which has high practicability.

[0059] 8. The cover plate on the back of the handrail can cover the various structures on the side of the handrail support, avoiding the problem of exposed frame, which is highly practical. Attached Figure Description

[0077] Step bolt 4 Detailed Implementation

[0078] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. In addition, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0079] Example 1:

[0080] like Figures 1-8 As shown, a rear seat with an angle-adaptive adjustable armrest structure according to the present invention includes:

[0081] 1. Seat cushion assembly installed on the vehicle body;

[0082] Backrest assembly 2, which includes backrest pivot 201, is hinged to the body via backrest pivot 201.

[0083] The armrest assembly 3 includes an armrest pivot 332, which is hinged to the backrest assembly 2 via the armrest pivot 332. The armrest pivot 332 is located above the backrest pivot 201.

[0084] When the armrest assembly 3 is rotated and laid flat around the armrest pivot 332, the seat cushion assembly 1 provides support for the armrest assembly 3.

[0085] Backrest assembly 2 is a six-point backrest assembly.

[0086] The armrest assembly 3 includes an armrest support structure. When the armrest assembly 3 is rotated and laid flat around the armrest pivot 332, the seat cushion assembly 1 provides support to the armrest assembly 3 through the armrest support structure.

[0087] In fact, the overall thickness of the handrail assembly 3 can also be increased according to actual conditions to raise the height of the upper end surface of the handrail assembly 3 after rotation and flattening. In the embodiment, the seat cushion assembly 1 supports the handrail assembly 3 through the handrail support structure, and the height of the upper end surface of the handrail assembly 3 after rotation and flattening can be raised without changing the overall thickness of the handrail assembly 3, thereby improving the comfort of passengers and having high practicability.

[0088] The handrail support structure is a headrest installed on the upper part of the handrail assembly 3.

[0089] In fact, the overall thickness of the headrest can also be directly increased according to actual conditions to raise the height of the upper end surface of the handrail assembly 3 after rotation and flattening. In the embodiment, the height of the upper end surface of the handrail assembly 3 after rotation and flattening can be raised without changing the overall thickness of the headrest, thereby improving the comfort of passengers and having high practicability.

[0090] The two sides of the headrest are provided with protruding features 30.

[0091] In fact, the overall thickness of the headrest can also be directly increased according to actual conditions to raise the height of the upper end surface of the handrail assembly 3 after rotation and flattening. In the embodiment, the height of the upper end surface of the handrail assembly 3 after rotation and flattening can be raised without changing the overall thickness of the headrest, thereby improving the comfort of passengers and having high practicability.

[0092] The surface materials of the handrail support structure and the seat cushion assembly 1 are selected to be mute materials.

[0093] In fact, the surface materials of the handrail support structure and the seat cushion assembly 1 can also be selected to be ordinary materials according to actual conditions. In the embodiment, the surface materials of the handrail support structure and the seat cushion assembly 1 are selected to be mute materials such as mute leather, thereby avoiding the problem of friction noise when the backrest assembly 2 rotates to drive the handrail assembly 3 to move relative to the seat cushion assembly 1, and further causing friction between the handrail support structure and the seat cushion assembly 1, and having high practicability.

[0094] The backrest assembly 2 includes a backrest framework assembly 21 and a backrest foam assembly.

[0095] The armrest assembly 3 comprises an armrest framework assembly 33 and an armrest foam assembly 31, and the backrest framework assembly 21 is fixedly installed with an auxiliary foam assembly below the armrest foam assembly 31. The armrest cup assembly 32 is fixed on the armrest framework assembly 33 through a clamping structure.

[0096] By arranging the auxiliary foam assembly, the armrest pivot 332 is raised in the horizontal direction to ensure that the rear end of the armrest assembly 3 has sufficient height in the horizontal direction when the armrest assembly 3 is used as a hand support for a passenger, and the armrest pivot 332 is arranged below the armrest framework assembly 33 to ensure that the lower end of the armrest assembly 3 has sufficient rotation freedom. The auxiliary foam assembly is arranged to block the gap between the armrest assembly 3 and the cushion assembly 1, thereby improving the comfort of the passenger when the armrest assembly 3 is used as a backrest and improving the appearance of the entire seat.

[0097] It should be noted that during the counterclockwise rotation of the backrest assembly 2, the gap 331 between the back surface of the armrest assembly 3 and the front end of the auxiliary foam assembly gradually decreases until the backrest assembly 2 is rotated counterclockwise to the maximum design position, at which time the gap 331 is zero, i.e., the back surface of the armrest assembly 3 abuts against the front end of the auxiliary foam assembly. This allows the movement envelope of the lower end of the armrest assembly 3 to be minimized and the space occupied to be minimized, thereby improving the practicability.

[0098] Of course, when the backrest assembly 2 is rotated counterclockwise to the maximum design position, the gap 331 is not zero, and the basic use requirements of the present application can also be met.

[0099] The backrest framework assembly 21 is fixedly installed with an armrest support 22, which can be fixed by welding or by screw connection, and the armrest support 22 is in the shape of a U.

[0100] The armrest framework assembly 33 is rotatably installed on the armrest support 22 via the armrest pivot 332.

[0101] In fact, the armrest framework assembly 33 can also be directly hinged to the backrest framework assembly 21 according to actual conditions. In the present embodiment, the armrest support 22 and the armrest pivot 332 are cooperated with each other to achieve the rotation connection between the armrest assembly 3 and the backrest assembly 2, and at the same time, the distance between the armrest pivot 332 and the backrest framework assembly 21 is increased, thereby reducing the interference between the armrest foam assembly 31 and the auxiliary foam assembly during the rotation of the armrest assembly 3 on the basis of ensuring that the armrest assembly 3 has sufficient rotation freedom, and the practicability is improved.

[0102] An arc-shaped channel 23 is formed in the side surface of the armrest support 22 with the armrest pivot 332 as the center, and the armrest framework assembly 33 is provided with an armrest limiting shaft 333 which is arranged in the arc-shaped channel 23.

[0103] The maximum rotation angle between the handrail assembly 3 and the backrest assembly 2 is limited by the cooperation of the handrail limiting shaft 333 and the arc-shaped channel 23, so that the handrail assembly 3 is prevented from rotating excessively, and the practicability is relatively high.

[0104] The handrail support plate 24 is installed on the side wall of the handrail support 22; the handrail support plate 24 is fixedly installed on the inner wall of the handrail support 22 through the self-tapping screw 25, and the step bolt 4 passes through the handrail mounting hole 242 in the side of the handrail support 22 and the handrail support plate 24 and is fixedly connected with the handrail rotating shaft 332.

[0105] The edge of the handrail support plate 24 is provided with an arc-shaped edge 240, and the side surface of the handrail limiting shaft 333 abuts against the arc-shaped edge 240.

[0106] In fact, the inner wall of the arc-shaped channel 23 can also be directly coated with plastic according to the actual situation. In the embodiment, the structure strength of the side wall of the handrail support 22 is strengthened through the arrangement of the handrail support plate 24, and the rotation of the handrail assembly 3 is resisted by the arc-shaped edge 240 through the contact between the handrail limiting shaft 333 and the arc-shaped edge 240, so that the handrail assembly 3 does not rotate too fast when being rotated, and the practicability is relatively high. Meanwhile, the handrail support plate 24 is used to replace the handrail support 22 to contact the handrail limiting shaft 333, and the handrail support plate 24 is made of plastic or other materials, so that the abnormal sound problem caused by the relative movement of the handrail limiting shaft 333 made of metal and the handrail support 22 made of metal after direct contact can be avoided, and the handrail support plate 24 can be directly replaced after the contact part is worn out after long-term use, without the need to replace the handrail support 22, and the practicability is relatively high.

[0107] The end portions of the handrail support plate 24 at both ends of the arc-shaped edge 240 are each provided with an arc-shaped feature 241.

[0108] When the handrail assembly 3 is rotated to the maximum position relative to the backrest assembly 2, the handrail limiting shaft 333 abuts against the arc-shaped feature 241.

[0109] The arc-shaped feature 241 is used to replace the handrail support 22 to support the handrail limiting shaft 333 when the handrail limiting shaft 333 is rotated to the maximum position, so that the abnormal sound problem caused by the collision between the handrail limiting shaft 333 and the handrail support 22 can be avoided, and the practicability is relatively high.

[0110] The arc-shaped channel 23 is two and is arranged on the two sides of the handrail support 22.

[0111] The handrail support plate 24 is two and is arranged on the two sides of the handrail support 22.

[0112] The handrail rotating shaft 332 is two and is arranged on the two sides of the handrail assembly 3.

[0113] In fact, the arc-shaped channel 23 and the handrail rotating shaft 332 can also be arranged on one side according to actual conditions. In the embodiment, the arc-shaped channel 23 and the handrail rotating shaft 332 are arranged on both sides, so that the handrail assembly 3 has limiting capacity on both sides when the handrail assembly 3 rotates clockwise to the maximum position relative to the handrail support 22. Compared with the arrangement of the arc-shaped channel 23 and the handrail rotating shaft 332 on one side, the arrangement of the arc-shaped channel 23 and the handrail rotating shaft 332 on both sides can reduce the possibility of the handrail assembly 3 deviating from the backrest assembly 2 when the handrail assembly 3 rotates clockwise to the maximum position relative to the handrail support 22, and has high practicability.

[0114] The lower part of one side of the handrail support 22 is provided with a first gap, and the first gap is communicated with one of the arc-shaped channels 23.

[0115] The lower part of the side of the handrail support plate 24 corresponding to the first gap is provided with a second gap.

[0116] Through the arrangement of the first gap and the second gap, one of the arc-shaped channels 23 and the arc-shaped edges 240 are damaged, so that only one arc-shaped edge 240 provides resistance to the rotation of the handrail assembly 3. On the basis of retaining that both sides of the handrail assembly 3 are limited when the handrail support 22 rotates clockwise to the maximum position, the assembly difficulty of the contact assembly between the handrail limiting shaft 333 and the arc-shaped edge 240 is reduced, and the practicability is high.

[0117] The outer side of the handrail support 22 is fixedly provided with a connecting arm 230 at the position of the first gap, and the middle part of the connecting arm 230 is curved outward.

[0118] The connecting arm 230 is arranged to fix both sides of the position of the first gap, so as to strengthen the structural strength of the handrail support 22 due to the first gap. At the same time, the curvature of the middle part of the connecting arm 230 avoids the sliding of the handrail limiting shaft 333 in the arc-shaped channel 23, and the practicability is high.

[0119] The backrest assembly 2 is further fixedly provided with a handrail back plate 26, and the two sides of the handrail back plate 26 are provided with shielding plates. The two shielding plates are located on the outer side of the handrail support 22.

[0120] The shielding plates on the handrail back plate 26 shield various structures on the side of the handrail support 22, so as to avoid the problem of skeleton leakage, and the practicability is high.

[0121] An automobile comprising the rear seat with the angle self-adaptive adjusting handrail structure.

[0122] In the embodiment, when the handrail assembly 3 is used as a backrest, the handrail assembly 3 is arranged on the backrest skeleton assembly 21 of the backrest assembly 2 and is fixed by the clamping mechanism. At this time, the handrail assembly 3 is matched with the periphery of the backrest assembly 2, like Figure 1 andFigure 2 As shown (wherein, the locking mechanism that fixes the armrest assembly 3 to the backrest assembly 2 is not related to the technical problem to be solved by this application, and belongs to the prior art, so this application will not describe it again);

[0123] When the armrest assembly 3 needs to be used as an armrest, it is turned so that the armrest assembly 3 rotates clockwise around the armrest pivot 332. During this process, the armrest limiting pivot 333 slides against the arc-shaped edge 240 of the armrest support plate 24 within the arc-shaped channel 23 until the protruding feature 30 rests against the seat cushion assembly 1 (e.g., Figure 3 (as shown);

[0124] When the armrest assembly 3 is used as an armrest, and the angle of the backrest assembly 2 needs to be adjusted, the backrest assembly 2 can be adjusted. During this process, the backrest assembly 2 rotates around the backrest pivot 201, causing the rear end of the armrest assembly 3 to change its position in the front-back direction, thereby causing the armrest assembly 3 to move.

[0125] During the movement of the armrest assembly 3, the front end of the armrest assembly 3 tends to droop downwards due to its own weight. At this time, supported by the raised feature 30 of the seat cushion assembly 1, the armrest assembly 3 automatically rotates around the armrest pivot 332, thereby keeping the armrest assembly 3 generally horizontal (e.g., Figure 4 (As shown).

[0126] Example 2:

[0127] like Figures 1-8 As shown, a rear seat with an angle-adaptive adjustable armrest structure according to the present invention includes:

[0128] 1. Seat cushion assembly installed on the vehicle body;

[0129] Backrest assembly 2, which includes backrest pivot 201, is hinged to the body via backrest pivot 201.

[0130] The armrest assembly 3 includes an armrest pivot 332, which is hinged to the backrest assembly 2 via the armrest pivot 332. The armrest pivot 332 is located above the backrest pivot 201.

[0131] When the armrest assembly 3 is rotated and laid flat around the armrest pivot 332, the seat cushion assembly 1 provides support for the armrest assembly 3.

[0132] Backrest assembly 2 is a six-point backrest assembly.

[0133] The seat cushion assembly 1 includes a seat cushion support structure. When the armrest assembly 3 is rotated and laid flat around the armrest pivot 332, the seat cushion assembly 1 provides support to the armrest assembly 3 through the seat cushion support structure.

[0134] In fact, the overall thickness of the armrest assembly 3 can also be increased according to actual conditions to raise the height of the upper end surface of the armrest assembly 3 after rotation and flattening. The seat cushion support structure is arranged to support the armrest assembly 3 through the seat cushion assembly 1, so that the height of the upper end surface of the armrest assembly 3 after rotation and flattening can be raised without changing the overall thickness of the armrest assembly 3, thereby improving the comfort of passengers and having high practicability.

[0135] The seat cushion assembly 1 is provided with a receiving groove at one end away from the backrest assembly 2, and the seat cushion support structure is hinged in the receiving groove.

[0136] In fact, the seat cushion support structure can also be directly fixed to the seat cushion assembly 1 according to actual conditions. In the embodiment, the seat cushion support structure is accommodated in the receiving groove, so that the existence of the seat cushion support structure does not affect the use of passengers when the armrest assembly 3 is used as a backrest. When the armrest assembly 3 is used as a hand support for passengers, the seat cushion support structure is rotated from the receiving groove to above the seat cushion assembly 1 to support the armrest assembly 3.

[0137] The surface materials of the seat cushion support structure and the backrest assembly 2 are both selected to be mute materials.

[0138] In fact, the surface materials of the seat cushion support structure and the seat cushion assembly 1 can also be selected to be ordinary materials according to actual conditions. In the embodiment, the surface materials of the seat cushion support structure and the seat cushion assembly 1 are both selected to be mute materials such as mute leather, so that the problem of friction noise can be avoided when the backrest assembly 2 is rotated to drive the armrest assembly 3 to move relative to the seat cushion assembly 1, and then the friction between the seat cushion support structure and the seat cushion assembly 1 occurs, thereby having high practicability.

[0139] The backrest assembly 2 comprises a backrest framework assembly 21 and a backrest foam assembly.

[0140] The armrest assembly 3 comprises an armrest framework assembly 33 and an armrest foam assembly 31. The backrest framework assembly 21 is fixedly installed below the armrest foam assembly 31 with an auxiliary foam assembly. The armrest cup holder assembly 32 is fixed on the armrest framework assembly 33 through a clamping structure.

[0141] The auxiliary foam assembly is arranged to block the gap between the armrest assembly 3 and the seat cushion assembly 1, so that the comfort of passengers when the armrest assembly 3 is used as a backrest is improved, and the appearance of the entire seat is also improved, thereby having high practicability.

[0142] It should be noted that, in the process of backrest assembly 2 counterclockwise rotation, the gap 331 between the backrest face of armrest assembly 3 and the front end of the auxiliary foam assembly gradually decreases until the backrest assembly 2 counterclockwise rotates to the maximum design position, at which time the gap 331 is zero, i.e. the backrest face of armrest assembly 3 abuts against the front end of the auxiliary foam assembly. This can minimize the movement envelope of the lower end of armrest assembly 3 and minimize the space occupied, and has strong practicality.

[0143] Of course, when the backrest assembly 2 counterclockwise rotates to the maximum design position, the gap 331 is not zero, and the basic use requirements of the present application can also be met.

[0144] The backrest skeleton assembly 21 is fixedly installed with an armrest support 22, and the fixing mode can be welding or fixed connection through bolts, and the armrest support 22 is in a U shape.

[0145] The armrest skeleton assembly 33 is rotatably installed on the armrest support 22 through an armrest pivot 332.

[0146] In fact, the armrest skeleton assembly 33 can also be directly hinged to the backrest skeleton assembly 21 according to actual conditions, and the present embodiment realizes the rotational connection between the armrest assembly 3 and the backrest assembly 2 through the cooperation of the U-shaped armrest support 22 and the armrest pivot 332, and increases the distance between the armrest pivot 332 and the backrest skeleton assembly 21, thereby reducing the interference between the armrest foam assembly 31 and the auxiliary foam assembly during the rotation of the armrest assembly 3 on the basis of ensuring sufficient rotational freedom of the armrest assembly 3, and has strong practicality.

[0147] An arc-shaped channel 23 is formed in the side surface of the armrest support 22 with the armrest pivot 332 as the center, and the armrest skeleton assembly 33 is provided with an armrest limiting shaft 333, which is arranged in the arc-shaped channel 23.

[0148] The armrest limiting shaft 333 and the arc-shaped channel 23 cooperate to limit the maximum rotation angle between the armrest assembly 3 and the backrest assembly 2, thereby preventing excessive rotation of the armrest assembly 3, and have strong practicality.

[0149] An armrest support plate 24 is installed on the side wall of the armrest support 22; the armrest support plate 24 is fixedly installed on the inner wall of the armrest support 22 through self-tapping screws 25, and the step bolts 4 pass through the armrest mounting holes 242 in the side surfaces of the armrest support 22 and the armrest support plate 24 and are fixedly connected with the armrest pivot 332.

[0150] The edge of the armrest support plate 24 is provided with an arc-shaped edge 240, and the side surface of the armrest limiting shaft 333 abuts against the arc-shaped edge 240.

[0151] In fact, the inner wall of the arc-shaped channel 23 can also be directly coated with plastic according to actual conditions. The present embodiment can strengthen the structural strength of the side wall of the handrail support 22 through the arrangement of the handrail support plate 24. In addition, the rotation of the handrail assembly 3 can be slowed down by the contact between the handrail limiting shaft 333 and the arc-shaped edge 240, which provides resistance to the rotation of the handrail assembly 3. When the handrail assembly 3 is rotated, the speed will not be too fast, which has high practicability. When the handrail support plate 24 is made of plastic or other materials, the noise caused by the relative movement of the metal handrail limiting shaft 333 and the metal handrail support 22 can be avoided. In addition, when the contact part is worn out after a long period of use, the handrail support plate 24 can be directly replaced without replacing the handrail support 22, which has high practicability.

[0152] The end of the handrail support plate 24 at both ends of the arc-shaped edge 240 is provided with an arc-shaped feature 241.

[0153] When the handrail assembly 3 is rotated to the maximum position relative to the backrest assembly 2, the handrail limiting shaft 333 abuts against the arc-shaped feature 241.

[0154] The arc-shaped feature 241 replaces the handrail support 22 to support the handrail limiting shaft 333 when the handrail limiting shaft 333 is rotated to the maximum position, which avoids the noise caused by the collision between the handrail limiting shaft 333 and the handrail support 22, which has high practicability.

[0155] The arc-shaped channel 23 is two and is arranged on both sides of the handrail support 22.

[0156] The handrail support plate 24 is two and is arranged on both sides of the handrail support 22.

[0157] The handrail rotating shaft 332 is two and is arranged on both sides of the handrail assembly 3.

[0158] In fact, only one side of the arc-shaped channel 23 and the handrail rotating shaft 332 can be arranged according to actual conditions. The present embodiment has two arc-shaped channels 23 and two handrail rotating shafts 332, which can provide limiting ability on both sides of the handrail assembly 3 when the handrail assembly 3 is rotated clockwise to the maximum position relative to the handrail support 22. Compared with the arrangement of the arc-shaped channel 23 and the handrail rotating shaft 332 on one side, the arrangement on both sides can reduce the possibility of deviation of the handrail assembly 3 relative to the backrest assembly 2 when the handrail assembly 3 is rotated clockwise to the maximum position relative to the handrail support 22, which has high practicability.

[0159] The lower part of one side of the handrail support 22 is provided with a first gap, and the first gap is in communication with one of the arc-shaped channels 23.

[0160] The lower part of the handrail support plate 24 on the side corresponding to the first gap is provided with a second gap.

[0161] By setting the first gap and the second gap, one of the arc-shaped channels 23 and the arc-shaped edge 240 is damaged, so that only one arc-shaped edge 240 provides resistance to the rotation of the handrail assembly 3, and the assembly difficulty of the contact assembly between the handrail limiting shaft 333 and the arc-shaped edge 240 is reduced while the two sides of the handrail assembly 3 are limited when the handrail support 22 rotates clockwise to the maximum position, and the practicability is higher.

[0162] The outer side of the handrail support 22 is fixedly provided with a connecting arm 230 at the position of the first gap, and the middle part of the connecting arm 230 is curved outward.

[0163] The two sides of the connecting arm 230 are fixed by the connecting arm 230 at the position of the first gap, which strengthens the structural strength of the handrail support 22 due to the first gap, and the sliding of the handrail limiting shaft 333 in the arc-shaped channel 23 is avoided by the curvature of the middle part of the connecting arm 230, and the practicability is higher.

[0164] The backrest assembly 2 is also fixedly provided with a handrail back plate 26, and the two sides of the handrail back plate 26 are provided with shielding plates, and the two shielding plates are located on the outer side of the handrail support 22.

[0165] The shielding plates on the handrail back plate 26 shield various structures on the side of the handrail support 22, avoiding the problem of skeleton leakage, and the practicability is higher.

[0166] In this embodiment, when the handrail assembly 3 is used as a backrest, the handrail assembly 3 is fixed on the backrest skeleton assembly 21 of the backrest assembly 2 by the clamping mechanism, at this time, the handrail assembly 3 is matched with the periphery of the backrest assembly 2, as shown in Figure 1 and Figure 2 It is shown (wherein the clamping mechanism for fixing the handrail assembly 3 on the backrest assembly 2 is irrelevant to the technical problem to be solved by the present application, and belongs to the prior art, so the present application will not be described again);

[0167] When the handrail assembly 3 is used as a handrail, the handrail assembly 3 is rotated clockwise around the handrail rotating shaft 332, in this process, the handrail limiting shaft 333 abuts against the arc-shaped edge 240 of the handrail support plate 24 and slides in the arc-shaped channel 23, until the handrail assembly 3 abuts against the cushion support structure;

[0168] When the handrail assembly 3 is used as a handrail, the angle of the backrest assembly 2 needs to be adjusted, the backrest assembly 2 can be adjusted, in this process, the backrest assembly 2 rotates around the backrest rotating shaft 201, drives the rear end of the handrail assembly 3 to change the position in the front and rear directions, and then drives the handrail assembly 3 to move;

[0169] During the movement of the armrest assembly 3, the front end of the armrest assembly 3 has a tendency to fall down under its own gravity, at this time, under the support of the seat cushion support structure to the armrest assembly 3, the armrest assembly 3 is automatically rotated around the armrest rotating shaft 332, so that the armrest assembly 3 is generally kept in a horizontal state (as shown in Figure 4 ).

[0170] The rear seat with the angle self-adaptive adjusting armrest structure and the car provided by the present application are described in detail above. The description of the specific embodiments is only used to help understand the method of the present application and its core idea. It should be pointed out that, for those skilled in the art, without departing from the principle of the present application, the present application can be improved and modified in many ways, and these improvements and modifications also fall within the protection scope of the claims of the present application.
