Description

Technical Field

[0001] The invention belongs to the technical field of automobile seats, and in particular relates to a rear seat with an angle-adaptive adjustable armrest structure and an automobile. Background Art

[0002] With the development of the automobile industry, the popularity of automobiles is increasing, and the market is paying more and more attention to the comfort of automobiles. Various comfort configurations have emerged. The adjustable rear seat backrest angle has also become one of the important comfort configurations of many models.

[0003] The adjustable backrest angle allows the rear seats to meet the needs of different groups of people, or different needs of the same person. However, the adjustable backrest angle also brings a problem: the middle armrest of the rear seat is fixed to the backrest. When the backrest angle is adjusted, the angle and height of the armrest support surface will change with the backrest angle, while the matching door armrest will not change, resulting in the inability to provide passengers with the same armrest comfort experience.

[0004] The Chinese invention patent (application number: CN201810896963.2) discloses a hinge structure, seat structure and automobile with adaptively adjustable armrest angle. The hinge structure uses a lock hook to lock the rear round tube of the armrest and cooperates with a spring to ensure that the backrest serving as the armrest remains in a horizontal state when the main backrest is folded backward.

[0005] That is, the turning limit of the armrest frame is achieved through the cooperation of the lock hook, the spring, the arc-shaped hole and the rear round tube of the armrest, so that the position of the armrest frame will not be affected when the backrest frame is turned over.

[0006] However, in the above patent, the position of the lock hook can coincide with the arc-shaped hole only when the backrest frame is in a specific position, so that the rear round tube of the armrest can enter the lock hook during the subsequent flipping process. When the backrest frame is in other positions, there is a problem that the position of the lock hook will be misaligned with the arc-shaped hole, which makes it impossible for the rear round tube of the armrest to smoothly enter the lock hook during the sliding process along the arc-shaped hole, and thus cannot be used normally. There are huge limitations in its use. Summary of the invention

[0007] The purpose of the present invention is to provide a rear seat and a car with an angle-adaptive armrest structure, which is used to solve the defects of the existing seat structure that result in no requirement on the inclination angle of the backrest assembly when the armrest assembly is converted from a backrest state to an armrest state, making it more convenient to use.

[0008] A rear seat with an angle-adaptive armrest structure, comprising:

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

[0010] A backrest assembly, the backrest assembly comprising a backrest rotating shaft, the backrest assembly being hinged to the vehicle body via the backrest rotating shaft;

[0011] An armrest assembly, the armrest assembly comprising an armrest rotating shaft, the armrest assembly being hinged to the backrest assembly via the armrest rotating shaft, and the armrest rotating shaft being located above the backrest rotating shaft;

[0012] When the armrest assembly is rotated and laid flat around the armrest rotation axis, the seat cushion assembly supports the armrest assembly.

[0013] It is further defined that the armrest assembly includes an armrest support structure, and when the armrest assembly is rotated around the armrest rotation axis and laid flat, the seat cushion assembly supports the armrest assembly through the armrest support structure.

[0014] Such a structural design, through the setting of the armrest support structure, enables the seat cushion assembly to support the armrest assembly through the armrest support structure. Without changing the overall thickness of the armrest assembly, the height of the upper end surface of the armrest assembly after rotation and flattening can be raised, thereby improving the comfort of the passengers and having strong practicality.

[0015] It is further defined that the armrest supporting structure is a headrest installed on the upper portion of the armrest assembly.

[0016] This structural design uses the headrest as the armrest supporting structure. When the armrest assembly is used as a backrest, the armrest supporting structure can be used as a headrest to provide support for the head of the passenger leaning against the armrest assembly, thereby improving the passenger's comfort and being highly practical.

[0017] It is further defined that the headrest has raised features on both sides.

[0018] Such a structural design, through the setting of the raised features, can raise the height of the upper end surface of the armrest assembly after it is rotated and laid flat, without changing the overall thickness of the headrest, thereby improving the comfort of the passengers; at the same time, when the armrest assembly is used as a backrest, it can also provide support for the passengers' heads on both sides, further improving the comfort of the passengers and being highly practical.

[0019] It is further defined that the surface materials of the armrest support structure and the seat cushion assembly are both made of sound-proof materials.

[0020] Such a structural design, by selecting sound-proof materials such as silent leather for the surface materials of the armrest support structure and the seat cushion assembly, can avoid the rotation of the backrest assembly, which drives the armrest assembly to move relative to the seat cushion assembly, thereby avoiding the problem of friction and abnormal noise when friction occurs between the armrest support structure and the seat cushion assembly, and is highly practical.

[0021] It is further defined that the seat cushion assembly includes a seat cushion support structure, and when the armrest assembly is rotated and laid flat around the armrest rotation axis, the seat cushion assembly supports the armrest assembly through the seat cushion support structure.

[0022] Such a structural design, through the setting of the seat cushion support structure, enables the seat cushion assembly to support the armrest assembly through the seat cushion support structure. Without changing the overall thickness of the armrest assembly, the height of the upper end surface of the armrest assembly after rotation and flattening can be raised, thereby improving the comfort of the passengers and having strong practicality.

[0023] It is further defined that a receiving groove is formed at one end of the seat cushion assembly away from the backrest assembly, and the seat cushion support structure is hinged in the receiving groove.

[0024] Such a structural design accommodates the seat cushion support structure through the accommodating groove, thereby preventing the existence of the seat cushion support structure from affecting the passenger's use when the armrest assembly is used as a backrest; and when the armrest assembly is used as a hand support for the passenger, the seat cushion support structure is rotated from the accommodating groove to the top of the seat cushion assembly to form a support for the armrest assembly.

[0025] It is further defined that the backrest assembly includes a backrest frame assembly and a backrest foam assembly;

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

[0027] Such a structural design, through the arrangement of an auxiliary foam assembly, in order to ensure that the rear end of the armrest assembly has a sufficient horizontal height when serving as a hand support for the passenger, the armrest shaft is raised in the horizontal height. At the same time, in order to ensure that the lower end of the armrest assembly has sufficient rotational freedom, the armrest shaft is arranged at the lower part of the armrest frame assembly, and the auxiliary foam assembly is used to block the gap between the armrest assembly and the seat cushion assembly, thereby improving the comfort of the passenger when using the armrest assembly as a backrest, and at the same time improving the aesthetics of the entire seat appearance, and it is highly practical.

[0028] It is further defined that an armrest bracket is fixedly mounted on the backrest frame assembly, and the armrest bracket is U-shaped;

[0029] The armrest frame assembly is rotatably mounted on the armrest bracket via the armrest rotating shaft.

[0030] Such a structural design, through the cooperation between the U-shaped armrest bracket and the armrest shaft, completes the rotational connection between the armrest assembly and the backrest assembly, while increasing the distance between the armrest shaft and the backrest frame assembly. This ensures that the armrest assembly has sufficient rotational freedom while reducing the interference between the armrest foam assembly and the auxiliary foam assembly when the armrest assembly rotates, and is highly practical.

[0031] It is further defined that an arc-shaped channel is opened on the side of the armrest bracket with the armrest rotating shaft as the center, and an armrest limiting shaft is provided on the side wall of the armrest frame assembly, and the armrest limiting shaft is passed through the arc-shaped channel.

[0032] Such a structural design limits the maximum rotation angle between the armrest assembly and the backrest assembly through the mutual cooperation between the armrest limit shaft and the arc-shaped channel, thereby avoiding excessive rotation of the armrest assembly and having strong practicality.

[0033] It is further defined that an armrest support plate is mounted on the side wall of the armrest bracket;

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

[0035] Such a structural design can strengthen the structural strength of the side wall of the armrest bracket by setting the armrest support plate, and can also provide resistance to the rotation of the armrest assembly by using the arc edge through the contact between the armrest limit shaft and the arc edge, so that the armrest assembly will not be rotated too fast, and it is more practical. At the same time, by using the armrest support plate instead of the armrest bracket to contact the armrest limit shaft, and using plastic and other materials to manufacture the armrest support plate, it is possible to avoid the problem of abnormal noise caused by relative movement after the metal armrest limit shaft and the metal armrest bracket are in direct contact. After long-term use, when the contact part is worn, the armrest support plate can be directly replaced without replacing the armrest bracket, and it is more practical.

[0036] It is further defined that the end portions of the armrest support plate at both ends of the arcuate edge are provided with arcuate features;

[0037] When the armrest assembly is rotated to a maximum position relative to the backrest assembly, the armrest limit shaft abuts against the arc-shaped feature.

[0038] This structural design uses an arc feature to replace the armrest bracket to support the armrest limit shaft when the armrest limit shaft rotates to the maximum position, thereby avoiding the problem of abnormal noise caused by direct collision between the armrest limit shaft and the armrest bracket, and is highly practical.

[0039] It is further defined that the arc-shaped channels are two and are respectively opened on both sides of the handrail bracket;

[0040] There are two armrest support plates, which are respectively located on both sides of the armrest bracket;

[0041] There are two armrest rotating shafts, one on each side of the armrest assembly.

[0042] Such a structural design, through the provision of two arc-shaped channels and two armrest shafts, enables both sides of the armrest assembly to have limiting capabilities when the armrest assembly is rotated clockwise to the maximum position relative to the armrest bracket. Compared with the method in which the arc-shaped channel and the armrest shaft are only provided on one side, the method in which both sides are provided can reduce the possibility of the armrest assembly being offset relative to the backrest assembly when the armrest assembly is rotated clockwise to the maximum position relative to the armrest bracket, and is more practical.

[0043] It is further defined that a first notch is provided at a lower portion of one side of the handrail bracket, and the first notch is connected to one of the arc-shaped channels;

[0044] A second notch is formed at the lower portion of the armrest support plate on a side corresponding to the first notch.

[0045] Such a structural 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 armrest assembly. While retaining the fact that both sides of the armrest assembly are limited when the armrest bracket rotates clockwise to the maximum position, the difficulty of contact assembly between the armrest limit axis and the arc-shaped edge is reduced, and the practicability is strong.

[0046] It is further defined that a connecting arm is fixedly provided on the outer side of the handrail bracket at the first notch position, and the middle part of the connecting arm is warped outward.

[0047] This structural design fixes both sides of the first notch position through the connecting arm, thereby strengthening the structural strength of the handrail bracket which is reduced due to the opening of the first notch. At the same time, through the warping of the middle part of the connecting arm, the sliding of the handrail limit axis in the arc channel is avoided, which is very practical.

[0048] It is further defined that an armrest back plate is also fixedly mounted on the backrest assembly, and shielding plates are provided on both sides of the armrest back plate, and the two shielding plates are both located on the outside of the armrest bracket.

[0049] This structural design uses the shielding plate on the armrest back panel to shield various structures on the side of the armrest bracket, avoiding the problem of the frame leaking out, and is very practical.

[0050] A car comprises the above-mentioned rear seat with an angle-adaptive adjustable armrest structure.

[0051] The invention adopting the above technical solution has the following advantages:

[0052] 1. The armrest assembly and the backrest assembly are hinged by the armrest shaft, and the armrest shaft supports the rear end of the armrest assembly, and cooperates with the seat cushion assembly to support the armrest assembly after it is rotated and laid flat, so as to limit the position of the armrest assembly; at the same time, even after the armrest assembly is rotated and laid flat, the backrest assembly continues to rotate around the backrest shaft to change the angle between the backrest assembly and the seat cushion assembly. The armrest assembly can also automatically rotate around the armrest shaft under the action of its own gravity and the support force of the seat cushion assembly, so that the armrest assembly can generally maintain a horizontal state;

[0053] 2. Through such structural design and arrangement, the rear seat armrest angle is adaptively adjusted without adding additional structures, and the appearance quality of the armrest in the folded state, flat state, and flat backrest adjustment state is taken into account, which is highly practical;

[0054] 3. By setting the armrest support structure, the seat cushion assembly supports the armrest assembly through the armrest support structure, and the height of the upper end surface of the armrest assembly after rotation and flattening can be raised without changing the overall thickness of the armrest assembly, thereby improving the comfort of passengers and having strong practicality;

[0055] 4. By setting the raised features, the height of the upper end surface of the armrest assembly after it is rotated and laid flat can be raised without changing the overall thickness of the headrest, thereby improving the comfort of the passengers; at the same time, when the armrest assembly is used as a backrest, it can also support the passenger's head on both sides, further improving the comfort of the passengers and having strong practicality;

[0056] 5. By setting the seat cushion support structure, the seat cushion assembly supports the armrest assembly through the seat cushion support structure, and the height of the upper end surface of the armrest assembly after rotating and flattening can be raised without changing the overall thickness of the armrest assembly, thereby improving the comfort of passengers and having strong practicality;

[0057] 6. Through the cooperation between the armrest limit shaft and the arc channel, the maximum rotation angle between the armrest assembly and the backrest assembly is limited to avoid excessive rotation of the armrest assembly, which is more practical;

[0058] 7. The armrest support plate can be provided to strengthen the structural strength of the side wall of the armrest bracket, and the armrest limit shaft can be in contact with the arc edge to provide resistance to the rotation of the armrest assembly, so that the armrest assembly will not rotate too fast when it is rotated, which is more practical. At the same time, the armrest support plate is used to contact the armrest limit shaft instead of the armrest bracket, and the armrest support plate is made of plastic and other materials. The abnormal noise problem caused by the relative movement of the metal armrest limit shaft and the metal armrest bracket can be avoided. After long-term use, when the contact part is worn, the armrest support plate can be directly replaced without replacing the armrest bracket, which is more practical.

[0059] 8. The shielding plate on the armrest back panel can be used to shield various structures on the side of the armrest bracket to avoid the problem of frame leakage, which is very practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0078] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that in the drawings or descriptions of the specification, similar or identical parts use the same figure numbers, and the implementation methods not shown or described in the drawings are forms known to ordinary technicians in the relevant technical field. In addition, the directional terms mentioned in the embodiments, such as "upper", "lower", "top", "bottom", "left", "right", "front", "back", etc., are only referenced to the directions of the drawings and are not used to limit the scope of protection of the present invention.

[0079] Embodiment 1:

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

[0081] A seat cushion assembly 1 mounted on a vehicle body;

[0082] The backrest assembly 2 includes a backrest shaft 201, and the backrest assembly 2 is hinged to the vehicle body via the backrest shaft 201;

[0083] The armrest assembly 3 includes an armrest shaft 332, the armrest assembly 3 is hinged to the backrest assembly 2 via the armrest shaft 332, and the armrest shaft 332 is located above the backrest shaft 201;

[0084] When the armrest assembly 3 is rotated and laid flat around the armrest rotation axis 332 , the seat cushion assembly 1 supports the armrest assembly 3 .

[0085] The backrest assembly 2 is a six-part 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 rotation axis 332 , the seat cushion assembly 1 supports the armrest assembly 3 via the armrest support structure.

[0087] In fact, according to actual conditions, the overall thickness of the armrest assembly 3 can be increased to raise the height of the upper end surface of the armrest assembly 3 after it is rotated and laid flat. In this embodiment, the armrest support structure is set so that the seat cushion assembly 1 supports the armrest assembly 3 through the armrest support structure. The height of the upper end surface of the armrest assembly 3 after it is rotated and laid flat can be raised without changing the overall thickness of the armrest assembly 3, thereby improving the comfort of the passengers and having strong practicality.

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

[0089] In fact, according to actual conditions, it is also possible to select an integrated lumbar pad in the middle of the armrest assembly 3 close to the seat cushion assembly 1, and use the lumbar pad as the armrest support structure. After the armrest assembly 3 is rotated and laid flat around the armrest shaft 332, support is formed for the armrest assembly 3. In this embodiment, a headrest is used as the armrest support structure. When the armrest assembly 3 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 3, thereby improving the comfort of the passenger and having strong practicality.

[0090] Raised features 30 are provided on both sides of the headrest.

[0091] In fact, according to actual conditions, it is also possible to choose a method such as directly thickening the overall thickness of the headrest to raise the height of the upper end surface of the armrest assembly 3 after it is rotated and laid flat. Through the provision of the raised feature 30, the height of the upper end surface of the armrest assembly 3 after it is rotated and laid flat can be raised without changing the overall thickness of the headrest, thereby improving the comfort of the passengers. At the same time, when the armrest assembly 3 is used as a backrest, it can also provide support for the passenger's head on both sides, further improving the comfort of the passengers, and having strong practicality.

[0092] The surface materials of the armrest support structure and the seat cushion assembly 1 are both made of silent materials.

[0093] In fact, according to actual conditions, a surface material of ordinary material can be selected as the surface material of the armrest support structure and the seat cushion assembly 1. In this embodiment, by selecting the surface materials of the armrest support structure and the seat cushion assembly 1 as silent materials such as silent leather, it is possible to avoid the rotation of the backrest assembly 2, which drives the armrest assembly 3 to move relative to the seat cushion assembly 1, thereby avoiding the problem of abnormal friction noise when friction occurs between the armrest support structure and the seat cushion assembly 1, and the practicality is strong.

[0094] The backrest assembly 2 includes a backrest frame assembly 21 and a backrest foam assembly;

[0095] The armrest assembly 3 includes an armrest frame assembly 33 and an armrest foam assembly 31. The backrest frame assembly 21 is fixedly mounted with an auxiliary foam assembly below the armrest foam assembly 31. The armrest cup holder assembly 32 is fixed to the armrest frame assembly 33 by a snap-on structure.

[0096] By setting the auxiliary foam assembly, in order to ensure that the rear end of the armrest assembly 3 has a sufficient horizontal height when serving as a hand support for the passenger, the armrest shaft 332 is raised in the horizontal height. At the same time, in order to ensure that the lower end of the armrest assembly 3 has sufficient rotational freedom, the armrest shaft 332 is set at the lower part of the armrest frame assembly 33. The auxiliary foam assembly is used to block the gap between the armrest assembly 3 and the cushion assembly 1, thereby improving the comfort of the passenger when using the armrest assembly 3 as a backrest, and at the same time improving the aesthetics of the entire seat appearance, and it is more practical.

[0097] It should be noted that, during the counterclockwise rotation of the backrest assembly 2, the gap 331 between the backrest surface of the armrest assembly 3 and the front end of the attached foam assembly gradually decreases until the backrest assembly 2 rotates counterclockwise to the maximum design position, at which time the gap 331 is zero, that is, the backrest surface of the armrest assembly 3 is against the front end of the attached foam assembly. This can minimize the motion envelope of the lower end of the armrest assembly 3, minimize the space occupied, and improve practicality.

[0098] Of course, when the backrest assembly 2 is rotated counterclockwise to the maximum design position, the gap 331 is not zero, which can also meet the basic usage requirements of this application.

[0099] An armrest bracket 22 is fixedly mounted on the backrest frame assembly 21, and the fixing method can be welding or fixed by bolts. The armrest bracket 22 is U-shaped;

[0100] The armrest frame assembly 33 is rotatably mounted on the armrest bracket 22 via the armrest rotating shaft 332 .

[0101] In fact, according to actual conditions, the armrest frame assembly 33 can be directly hinged on the backrest frame assembly 21 close to the backrest frame assembly 21. This embodiment completes the rotational connection between the armrest assembly 3 and the backrest assembly 2 through the cooperation between the U-shaped armrest bracket 22 and the armrest shaft 332, while increasing the distance between the armrest shaft 332 and the backrest frame assembly 21. This reduces the interference between the armrest foam assembly 31 and the auxiliary foam assembly when the armrest assembly 3 rotates while ensuring that the armrest assembly 3 has sufficient rotational freedom, thereby having strong practicality.

[0102] An arc-shaped channel 23 is formed on the side of the armrest bracket 22 with the armrest rotating shaft 332 as the center. An armrest limiting shaft 333 is formed on the side wall of the armrest frame assembly 33 . The armrest limiting shaft 333 passes through the arc-shaped channel 23 .

[0103] Through the cooperation between the armrest limit shaft 333 and the arc channel 23, the maximum rotation angle between the armrest assembly 3 and the backrest assembly 2 is limited to avoid excessive rotation of the armrest assembly 3, which is highly practical.

[0104] An armrest support plate 24 is installed on the side wall of the armrest bracket 22; the armrest support plate 24 is fixedly installed on the inner wall of the armrest bracket 22 by self-tapping screws 25, and the step bolt 4 passes through the armrest mounting hole 242 on the side of the armrest bracket 22 and the armrest support plate 24, and is fixedly connected to the armrest shaft 332;

[0105] An arc-shaped edge 240 is provided at the edge of the armrest support plate 24 , and the side surface of the armrest limiting shaft 333 rests on the arc-shaped edge 240 .

[0106] In fact, according to actual conditions, the inner wall of the arc-shaped channel 23 can be directly coated with plastic. In this embodiment, the structural strength of the side wall of the armrest bracket 22 can be strengthened by the arrangement of the armrest support plate 24. The armrest limiting shaft 333 can also be in contact with the arc-shaped edge 240, and the arc-shaped edge 240 can be used to provide resistance to the rotation of the armrest assembly 3, so that the armrest assembly 3 will not be rotated too fast when it is rotated, and it is more practical. At the same time, the armrest support plate 24 is used to contact the armrest limiting shaft 333 instead of the armrest bracket 22, and the armrest support plate 24 is manufactured with materials such as plastic. This can avoid the problem of abnormal noise caused by relative movement after the metal armrest limiting shaft 333 and the metal armrest bracket 22 are in direct contact. After long-term use, when the contact part is worn, the armrest support plate 24 can be directly replaced without replacing the armrest bracket 22, and it is more practical.

[0107] The armrest support plate 24 is provided with arc-shaped features 241 at the ends of both ends of the arc-shaped edge 240;

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

[0109] The arc feature 241 replaces the armrest bracket 22 to support the armrest limit shaft 333 when the armrest limit shaft 333 rotates to the maximum position, thereby avoiding the problem of abnormal noise caused by the direct collision between the armrest limit shaft 333 and the armrest bracket 22, and is more practical.

[0110] There are two arc-shaped channels 23, which are respectively opened on both sides of the handrail bracket 22;

[0111] There are two armrest support plates 24, which are respectively located on both sides of the armrest bracket 22;

[0112] There are two armrest rotating shafts 332 , one on each side of the armrest assembly 3 .

[0113] In fact, according to actual conditions, the arc channel 23 and the armrest shaft 332 can be set only on one side. In this embodiment, the arc channel 23 and the armrest shaft 332 are set in two, so that when the armrest assembly 3 is rotated clockwise to the maximum position relative to the armrest bracket 22, both sides of the armrest assembly 3 have limiting capabilities. Compared with the method of setting the arc channel 23 and the armrest shaft 332 only on one side, the method of setting them on both sides can reduce the possibility of the armrest assembly 3 being offset relative to the backrest assembly 2 when the armrest assembly 3 is rotated clockwise to the maximum position relative to the armrest bracket 22, which is more practical.

[0114] A first notch is formed at the lower portion of one side of the handrail bracket 22, and the first notch is connected to one of the arc-shaped channels 23;

[0115] A second notch is formed in the lower portion of the armrest support plate 24 on the side corresponding to the first notch.

[0116] By setting the first notch and the second notch, one of the arc channels 23 and the arc edge 240 is destroyed, so that only one arc edge 240 provides resistance to the rotation of the armrest assembly 3. On the basis of retaining that when the armrest bracket 22 rotates clockwise to the maximum position, both sides of the armrest assembly 3 are limited, the difficulty of contact assembly between the armrest limit shaft 333 and the arc edge 240 is reduced, and the practicability is strong.

[0117] A connecting arm 230 is fixedly provided on the outer side of the handrail bracket 22 at the position of the first notch, and the middle part of the connecting arm 230 is warped outward.

[0118] The connecting arm 230 is used to fix both sides of the first notch position, thereby reinforcing the structural strength of the armrest bracket 22 which is reduced due to the opening of the first notch. At the same time, by warping the middle part of the connecting arm 230, the sliding of the armrest limit shaft 333 in the arc channel 23 is avoided, which is highly practical.

[0119] An armrest back plate 26 is also fixedly mounted on the backrest assembly 2 , and shielding plates are provided on both sides of the armrest back plate 26 , and the two shielding plates are both located on the outside of the armrest bracket 22 .

[0120] The shielding plate on the armrest back plate 26 can shield various structures on the side of the armrest bracket 22 to avoid the problem of the frame leaking out, which is very practical.

[0121] A car comprises the above-mentioned rear seat with an angle-adaptive adjustable armrest structure.

[0122] In this embodiment, when the armrest assembly 3 is used as a backrest, the armrest assembly 3 is placed on the backrest frame assembly 21 of the backrest assembly 2 and fixed by a clamping mechanism. At this time, the armrest assembly 3 fits the periphery of the backrest assembly 2, such as Figure 1 and Figure 2 As shown (wherein, the clamping mechanism for fixing the armrest 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 repeat it);

[0123] When the armrest assembly 3 is used as an armrest, the armrest assembly 3 is pulled to rotate clockwise around the armrest rotation axis 332. During this process, the armrest limit shaft 333 abuts against the arcuate edge 240 of the armrest support plate 24 and slides in the arcuate channel 23 until the raised feature 30 abuts against the seat cushion assembly 1 (such as Figure 3 shown);

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

[0125] During the movement of the armrest assembly 3, the front end of the armrest assembly 3 has a tendency to droop downward under its own gravity. At this time, under the support of the raised features 30 of the seat cushion assembly 1, the armrest assembly 3 is driven to automatically rotate around the armrest shaft 332, so that the armrest assembly 3 is generally kept in a horizontal state (such as Figure 4 shown).

[0126] Embodiment 2:

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

[0128] A seat cushion assembly 1 mounted on a vehicle body;

[0129] The backrest assembly 2 includes a backrest shaft 201, and the backrest assembly 2 is hinged to the vehicle body via the backrest shaft 201;

[0130] The armrest assembly 3 includes an armrest shaft 332, the armrest assembly 3 is hinged to the backrest assembly 2 via the armrest shaft 332, and the armrest shaft 332 is located above the backrest shaft 201;

[0131] When the armrest assembly 3 is rotated and laid flat around the armrest rotation axis 332 , the seat cushion assembly 1 supports the armrest assembly 3 .

[0132] The backrest assembly 2 is a six-part 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 rotation axis 332, the seat cushion assembly 1 supports the armrest assembly 3 via the seat cushion support structure.

[0134] In fact, according to actual conditions, the overall thickness of the armrest assembly 3 can be increased to raise the height of the upper end surface of the armrest assembly 3 after it is rotated and laid flat. In this embodiment, the seat cushion support structure is set so that the seat cushion assembly 1 supports the armrest assembly 3 through the seat cushion support structure. Without changing the overall thickness of the armrest assembly 3, the height of the upper end surface of the armrest assembly 3 after it is rotated and laid flat can be raised, thereby improving the comfort of the passengers and having strong practicality.

[0135] An accommodating groove is provided at one end of the seat cushion assembly 1 away from the backrest assembly 2, and the seat cushion supporting structure is hinged in the accommodating groove.

[0136] In fact, according to actual conditions, it is also possible to choose to fix the seat cushion support structure directly on the seat cushion assembly 1. In this embodiment, the seat cushion support structure is accommodated by a receiving groove to avoid the existence of the seat cushion support structure when the armrest assembly 3 is used as a backrest, which affects the passenger's use; and when the armrest assembly 3 is used as a hand support for the passenger, the seat cushion support structure is rotated from the receiving groove to the top of the seat cushion assembly 1 to form a support for the armrest assembly 3.

[0137] The surface materials of the seat cushion support structure and the backrest assembly 2 are both made of silent materials.

[0138] In fact, according to actual conditions, a surface material of ordinary material can be selected as the surface material of the armrest support structure and the seat cushion assembly 1. In this embodiment, by selecting the surface materials of the armrest support structure and the seat cushion assembly 1 as silent materials such as silent leather, it is possible to avoid the rotation of the backrest assembly 2, which drives the armrest assembly 3 to move relative to the seat cushion assembly 1, thereby avoiding the problem of abnormal friction noise when friction occurs between the armrest support structure and the seat cushion assembly 1, and the practicality is strong.

[0139] The backrest assembly 2 includes a backrest frame assembly 21 and a backrest foam assembly;

[0140] The armrest assembly 3 includes an armrest frame assembly 33 and an armrest foam assembly 31. The backrest frame assembly 21 is fixedly mounted with an auxiliary foam assembly below the armrest foam assembly 31. The armrest cup holder assembly 32 is fixed to the armrest frame assembly 33 by a snap-on structure.

[0141] By setting the auxiliary foam assembly, in order to ensure that the rear end of the armrest assembly 3 has a sufficient horizontal height when serving as a hand support for the passenger, the armrest shaft 332 is raised in the horizontal height. At the same time, in order to ensure that the lower end of the armrest assembly 3 has sufficient rotational freedom, the armrest shaft 332 is set at the lower part of the armrest frame assembly 33. The auxiliary foam assembly is used to block the gap between the armrest assembly 3 and the cushion assembly 1, thereby improving the comfort of the passenger when using the armrest assembly 3 as a backrest, and at the same time improving the aesthetics of the entire seat appearance, and it is more practical.

[0142] It should be noted that, during the counterclockwise rotation of the backrest assembly 2, the gap 331 between the backrest surface of the armrest assembly 3 and the front end of the attached foam assembly gradually decreases until the backrest assembly 2 rotates counterclockwise to the maximum design position, at which time the gap 331 is zero, that is, the backrest surface of the armrest assembly 3 is against the front end of the attached foam assembly. This can minimize the motion envelope of the lower end of the armrest assembly 3, minimize the space occupied, and improve practicality.

[0143] Of course, when the backrest assembly 2 is rotated counterclockwise to the maximum design position, the gap 331 is not zero, which can also meet the basic usage requirements of this application.

[0144] An armrest bracket 22 is fixedly mounted on the backrest frame assembly 21, and the fixing method can be welding or fixed by bolts. The armrest bracket 22 is U-shaped;

[0145] The armrest frame assembly 33 is rotatably mounted on the armrest bracket 22 via the armrest rotating shaft 332 .

[0146] In fact, according to actual conditions, the armrest frame assembly 33 can be directly hinged on the backrest frame assembly 21 close to the backrest frame assembly 21. This embodiment completes the rotational connection between the armrest assembly 3 and the backrest assembly 2 through the cooperation between the U-shaped armrest bracket 22 and the armrest shaft 332, while increasing the distance between the armrest shaft 332 and the backrest frame assembly 21. This reduces the interference between the armrest foam assembly 31 and the auxiliary foam assembly when the armrest assembly 3 rotates while ensuring that the armrest assembly 3 has sufficient rotational freedom, thereby having strong practicality.

[0147] An arc-shaped channel 23 is formed on the side of the armrest bracket 22 with the armrest rotating shaft 332 as the center. An armrest limiting shaft 333 is formed on the side wall of the armrest frame assembly 33 . The armrest limiting shaft 333 passes through the arc-shaped channel 23 .

[0148] Through the cooperation between the armrest limit shaft 333 and the arc channel 23, the maximum rotation angle between the armrest assembly 3 and the backrest assembly 2 is limited to avoid excessive rotation of the armrest assembly 3, which is highly practical.

[0149] An armrest support plate 24 is installed on the side wall of the armrest bracket 22; the armrest support plate 24 is fixedly installed on the inner wall of the armrest bracket 22 by self-tapping screws 25, and the step bolt 4 passes through the armrest mounting hole 242 on the side of the armrest bracket 22 and the armrest support plate 24, and is fixedly connected to the armrest shaft 332;

[0150] An arc-shaped edge 240 is provided at the edge of the armrest support plate 24 , and the side surface of the armrest limiting shaft 333 rests on the arc-shaped edge 240 .

[0151] In fact, according to actual conditions, the inner wall of the arc-shaped channel 23 can be directly coated with plastic. In this embodiment, the structural strength of the side wall of the armrest bracket 22 can be strengthened by the arrangement of the armrest support plate 24. The armrest limiting shaft 333 can also be in contact with the arc-shaped edge 240, and the arc-shaped edge 240 can be used to provide resistance to the rotation of the armrest assembly 3, so that the armrest assembly 3 will not be rotated too fast when it is rotated, and it is more practical. At the same time, the armrest support plate 24 is used to contact the armrest limiting shaft 333 instead of the armrest bracket 22, and the armrest support plate 24 is manufactured with materials such as plastic. This can avoid the problem of abnormal noise caused by relative movement after the metal armrest limiting shaft 333 and the metal armrest bracket 22 are in direct contact. After long-term use, when the contact part is worn, the armrest support plate 24 can be directly replaced without replacing the armrest bracket 22, and it is more practical.

[0152] The armrest support plate 24 is provided with arc-shaped features 241 at the ends of both ends of the arc-shaped edge 240;

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

[0154] The arc feature 241 replaces the armrest bracket 22 to support the armrest limit shaft 333 when the armrest limit shaft 333 rotates to the maximum position, thereby avoiding the problem of abnormal noise caused by the direct collision between the armrest limit shaft 333 and the armrest bracket 22, and is more practical.

[0155] There are two arc-shaped channels 23, which are respectively opened on both sides of the handrail bracket 22;

[0156] There are two armrest support plates 24, which are respectively located on both sides of the armrest bracket 22;

[0157] There are two armrest rotating shafts 332 , one on each side of the armrest assembly 3 .

[0158] In fact, according to actual conditions, the arc channel 23 and the armrest shaft 332 can be set only on one side. In this embodiment, the arc channel 23 and the armrest shaft 332 are set in two, so that when the armrest assembly 3 is rotated clockwise to the maximum position relative to the armrest bracket 22, both sides of the armrest assembly 3 have limiting capabilities. Compared with the method of setting the arc channel 23 and the armrest shaft 332 only on one side, the method of setting them on both sides can reduce the possibility of the armrest assembly 3 being offset relative to the backrest assembly 2 when the armrest assembly 3 is rotated clockwise to the maximum position relative to the armrest bracket 22, which is more practical.

[0159] A first notch is formed at the lower portion of one side of the handrail bracket 22, and the first notch is connected to one of the arc-shaped channels 23;

[0160] A second notch is formed in the lower portion of the armrest support plate 24 on the side corresponding to the first notch.

[0161] By setting the first notch and the second notch, one of the arc channels 23 and the arc edge 240 is destroyed, so that only one arc edge 240 provides resistance to the rotation of the armrest assembly 3. On the basis of retaining that when the armrest bracket 22 rotates clockwise to the maximum position, both sides of the armrest assembly 3 are limited, the difficulty of contact assembly between the armrest limit shaft 333 and the arc edge 240 is reduced, and the practicability is strong.

[0162] A connecting arm 230 is fixedly provided on the outer side of the handrail bracket 22 at the position of the first notch, and the middle part of the connecting arm 230 is warped outward.

[0163] The connecting arm 230 is used to fix both sides of the first notch position, thereby reinforcing the structural strength of the armrest bracket 22 which is reduced due to the opening of the first notch. At the same time, by warping the middle part of the connecting arm 230, the sliding of the armrest limit shaft 333 in the arc channel 23 is avoided, which is highly practical.

[0164] An armrest back plate 26 is also fixedly mounted on the backrest assembly 2 , and shielding plates are provided on both sides of the armrest back plate 26 , and the two shielding plates are both located on the outside of the armrest bracket 22 .

[0165] The shielding plate on the armrest back plate 26 can shield various structures on the side of the armrest bracket 22 to avoid the problem of the frame leaking out, which is very practical.

[0166] In this embodiment, when the armrest assembly 3 is used as a backrest, the armrest assembly 3 is placed on the backrest frame assembly 21 of the backrest assembly 2 and fixed by a clamping mechanism. At this time, the armrest assembly 3 fits the periphery of the backrest assembly 2, such as Figure 1 and Figure 2 As shown (wherein, the clamping mechanism for fixing the armrest 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 repeat it);

[0167] When the armrest assembly 3 needs to be used as an armrest, the armrest assembly 3 is pulled to rotate the armrest assembly 3 clockwise around the armrest rotation axis 332. During this process, the armrest limit axis 333 abuts against the arcuate edge 240 of the armrest support plate 24 and slides in the arcuate channel 23 until the armrest assembly 3 abuts against the seat cushion support structure.

[0168] When the armrest assembly 3 is used as an armrest, when the angle of the backrest assembly 2 needs to be adjusted, the backrest assembly 2 can be used. During this process, the backrest assembly 2 rotates around the backrest rotation axis 201, driving the rear end of the armrest assembly 3 to change its position in the front-to-back direction, thereby driving the armrest 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 droop downward under its own gravity. At this time, under the support of the seat cushion support structure on the armrest assembly 3, the armrest assembly 3 is driven to automatically rotate around the armrest rotation axis 332, so that the armrest assembly 3 is generally kept in a horizontal state (such as Figure 4 shown).

The description of the specific embodiment is only used to help understand the method and core idea of ​​the present invention.
