Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0028] like Figures 2 to 4 As shown, in order to solve the problem that the existing armrest hinge occupies a large movement space during the entire movement process. The present invention proposes an armrest, including an armrest hinge structure 100, an armrest cover 6 and an armrest seat 7, the armrest hinge structure 100 includes a hinge device 2 and a rotating hinge arm 1, the hinge device 2 includes a fixed hinge arm 21 and a connecting member 22, the rotating hinge arm 1 has a first hinge part (for example, provided in the interior of the first plastic body 3 described below), the fixed hinge arm 21 has a second hinge part (for example, provided in the interior of the second plastic body 4 described below), the first hinge part and the second hinge part are rotatably connected, and the connecting member 22 is provided between the rotating hinge arm 1 and the fixed hinge arm 21; when the rotating hinge arm 1 rotates to the first position, refer to Figure 2 and Figure 4 , the rotating articulated arm 1, the connecting member 22, and the fixed articulated arm 21 are superimposed together, and when the rotating articulated arm 1 is rotated to the second position, refer to Figure 3, the rotating hinge arm 1, the connecting piece 22, and the fixed hinge arm 21 are unfolded, and the connecting piece 22 is connected to the rotating hinge arm 1 and the fixed hinge arm 21, so that the rotating hinge arm 1 stops when it rotates to the second position; wherein, a first notch 71 is provided on the armrest seat 7, and a second notch 61 is provided on the armrest cover 6, and the fixed hinge arm 21 is fixed in the armrest seat 7, and the rotating connecting arm extends from the first notch 71 and extends into the armrest cover 6 through the second notch 61 and is fixed to the armrest cover 6, for example, the rotating connecting arm is connected or clamped in the armrest cover 6 by a bolt 23, so that when the rotating hinge arm 1 rotates from the first position to the second position relative to the fixed hinge arm 21, the armrest cover 6 is opened from the armrest seat 7, and when the rotating hinge arm 1 rotates from the second position to the first position relative to the fixed hinge arm 21, the armrest cover 6 is closed at the armrest seat 7. It can be understood that the overlapping of the rotating articulated arm 1 , the connecting piece 22 and the fixed articulated arm 21 means that the side of the rotating articulated arm 1 close to the hinge point, the side of the fixed articulated arm 21 close to the hinge point and the connecting piece 22 overlap.

[0029] Since when the rotating articulated arm 1 is rotated to the second position, the rotating articulated arm 1, the connecting member 22 and the fixed articulated arm 21 are unfolded, and the connecting member 22 is respectively connected to the rotating articulated arm 1 and the fixed articulated arm 21, when the rotating articulated arm 1 is rotated to the first position, the rotating articulated arm 1, the connecting member 22 and the fixed articulated arm 21 are overlapped together, so that in the movement stroke of opening the armrest, the armrest hinge structure 100 can be unfolded in sections and steps, and can be stopped when the rotating articulated arm 1 is rotated to the second position. In the movement stroke of closing the armrest, the unfolded part of the armrest hinge structure 100 can be folded together, so that the rotating articulated arm 1 does not invade the space behind the fixed articulated arm 21. It can be understood that the back side of the fixed articulated arm 21 refers to the side of the fixed articulated arm 21 away from the opening of the armrest cover 6.

[0030] The specific implementation of the armrest hinge structure 100 of the present invention is introduced below.

[0031] Possibly, the hinge device 2 further includes a bolt 23. In the present invention, the screw portion of the bolt 23 is used as an axis 231, so that the first hinge portion is rotatably connected to the second hinge portion through the axis 231, and the connecting member 22 is rotatably connected between the first hinge portion and the second hinge portion through the axis 231. Specifically, the connection member 22 is rotatably connected between the first hinge portion and the second hinge portion through the axis 231. The arrangement method can be: the connecting member 22 includes a plurality of intermediate bodies 221, each intermediate body 221 has a third hinge portion (for example, provided inside the third plastic body 5 described below), and each third hinge portion is rotatably connected to the first hinge portion through the axis 231. Between the connecting part and the second hinge part, in this case, when the rotating hinge arm 1 rotates to the second position, the intermediate bodies 221 are unfolded and overlapped with each other, and the intermediate body 221 close to the rotating connecting arm overlaps with the rotating connecting arm, and the intermediate body 221 close to the fixed hinge arm 21 overlaps with the fixed hinge arm 21. When the rotating hinge arm 1 rotates to the first position, the intermediate bodies 221 are superimposed together, and the overlapping parts of the intermediate bodies 221, the overlapping parts of the intermediate bodies 221 close to the rotating connecting arm and the rotating connecting arm, and the overlapping parts of the intermediate body 221 close to the fixed hinge arm 21 and the fixed hinge arm 21 are all disengaged from each other.

[0032] It can be understood that the first hinge part, the second hinge part and the third hinge part are all provided with mounting holes, and the shaft body 231 is provided in the mounting holes of the first hinge part, the second hinge part and the third hinge part, wherein the shaft body 231 can be fixedly mounted on the inner wall of the armrest seat 7. In this case, the mounting holes of the first hinge part and the third hinge part can be loosely matched with the shaft body 231, so that the first hinge part and the third hinge part can rotate around the shaft body 231. Since the fixed hinge arm 21 is fixedly mounted in the armrest seat 7, the mounting hole of the second hinge part can be With interference fit or clearance fit with the shaft 231; of course, the shaft 231 can also be rotatably installed on the inner wall of the armrest seat 7. In this case, the mounting hole of the first hinge part can be interference fit with the shaft 231, so that when the first hinge part rotates, the shaft 231 is driven to rotate, and the mounting holes of the second hinge part and the third hinge part can be clearance fit with the shaft 231. As long as the rotating hinge arm 1 and the connecting member 22 can rotate relative to the fixed hinge arm 21, the setting method can be appropriately adjusted, which is within the protection scope of the present invention.

[0033] In addition, it can be understood that since the third hinge portion of each intermediate body 221 can be rotatably connected to the shaft body 231, the intermediate bodies 221 are arranged side by side on the shaft body 231, and since the third hinge portion of each intermediate body 221 is connected between the first hinge portion and the second hinge portion, it can be known that the intermediate body 221 close to the side of the fixed hinge arm 21 and the intermediate body 221 close to the side of the rotating hinge arm 1 are respectively located on the opposite sides of the connecting body.

[0034] It can be understood that the overlap described above refers to connecting the structures together through the action of force, and the overlap methods include various. For example, the fixed hinge arm 21 has a first flange 211, each intermediate body 221 has a second flange 2211 and a third flange 2212, and the rotating hinge arm 1 has a fourth flange 11, wherein the first flange 211 is bent toward the side close to the intermediate body 221, each second flange 2211 is bent toward the side close to the fixed hinge arm 21, each third flange 2212 is bent toward the side close to the rotating hinge arm 1, and the fourth flange 11 is bent toward the side close to the intermediate body 221; so that when the rotating hinge arm 1 rotates to the second position, the first flange 211 and the second flange 2211 of the intermediate body 221 close to the side of the fixed hinge arm 21 are overlapped by surface fitting, and each intermediate body 2 The third flange 2212 and the second flange 2211 between 21 are overlapped together by surface fitting, and the third flange 2212 of the intermediate body 221 close to the side of the rotating connecting arm and the fourth flange 11 are overlapped together by surface fitting, thereby realizing the expansion between the fixed hinged arm 21, each intermediate body 221, and the rotating hinged arm 1, and the stop of the intermediate body 221 and the rotating connecting arm. When the rotating hinged arm 1 rotates to the first position, the first flange 211 and the second flange 2211 of the intermediate body 221 close to the side of the fixed hinged arm 21, the third flange 2212 and the second flange 2211 between each intermediate body 221, and the third flange 2212 and the fourth flange 11 of the intermediate body 221 close to the side of the rotating connecting arm are disengaged from each other and arranged accordingly, so that the fixed hinged arm 21, each intermediate body 221, and the rotating hinged arm 1 are overlapped together.

[0035] Of course, the overlapping method can also be through a locking hook and a locking ring, and the locking hook can be inserted into the locking ring. At this time, the locking ring and the locking hook are overlapped and abutted, and the locking hook can also be released from the locking ring. For example, the fixed hinged arm 21 includes a first locking ring, the intermediate body 221 includes a first locking hook and a second locking ring, and the rotating connecting arm includes a second locking hook. When the rotating hinged arm 1 rotates to the second position, the first locking ring overlaps the first locking hook of the intermediate body 221 close to the side of the fixed hinged arm 21, the second locking ring between the intermediate bodies 221 overlaps the first locking hook, and the second locking ring of the intermediate body 221 close to the side of the rotating connecting arm overlaps the second locking hook, thereby realizing the stopping of the intermediate body 221 and the rotating connecting arm. When the rotating hinged arm 1 rotates to the first position, the first locking ring and the first locking hook of the intermediate body 221 close to the side of the fixed hinged arm 21, the second locking ring between the intermediate bodies 221 and the first locking hook, and the second locking ring and the second locking hook of the intermediate body 221 close to the side of the rotating connecting arm are all disengaged from each other.

[0036] Its working process includes: in the movement stroke of opening the armrest, each intermediate body 221 and the rotating connecting arm gradually expands, and is overlapped by the overlapping method described above to achieve the stop position of the intermediate body 221 and the rotating connecting arm; in the movement stroke of closing the armrest, the intermediate body 221 is finally overlapped with the fixed hinged arm 21 and the rotating hinged arm 1 under the action of gravity.

[0037] Possibly, the periphery of the first hinged part is covered with a first plastic body 3, and the rotating hinged arm 1 is integrally injection-molded with the first plastic body 3; the periphery of the second hinged part is covered with a second plastic body 4, and the fixed hinged arm 21 is integrally injection-molded with the second plastic body 4; the periphery of each third hinged part is covered with a third plastic body 5, and each intermediate body 221 is integrally injection-molded with its corresponding third plastic body 5; there is frictional contact between the first plastic body 3 and the third plastic body 5, between adjacent third plastic bodies 5, and between the third plastic body 5 and the second plastic body 4.

[0038] Among them, after the bolt 23 is installed on the armrest seat 7, the first plastic body 3 and the third plastic body 5, the third plastic bodies 5, and the third plastic body 5 and the second plastic body 4 can be tightened by adjusting the nut that cooperates with the bolt 23 to achieve mutual friction between the plastic bodies.

[0039] This arrangement allows the rotating hinge arm 1 and intermediate body 221 to descend slowly during the armrest closing motion, preventing the armrest cover 6 from violently impacting the armrest base 7 under the action of gravity, which could affect the armrest's service life. Furthermore, the aforementioned one-piece injection molding method enhances the connection strength between the plastic body and the corresponding components, thereby increasing the overall structural strength of the armrest hinge structure 100 and its service life. It also avoids the complexity of installation caused by a large variety of accessories.

[0040] Preferably, there are two intermediate bodies 221. For ease of explanation, the intermediate body 221 near the fixed hinged arm 21 is referred to as the first intermediate body, and the intermediate body 221 near the rotating hinged arm 1 is referred to as the second intermediate body. The first intermediate body, after being opened 30 degrees with the fixed hinged arm 21, overlaps and stops with the fixed hinged arm 21. The second intermediate body, after being opened 30 degrees with the first intermediate body, overlaps and stops with the first intermediate body. The rotating hinged arm 1, after being opened 30 degrees with the second intermediate body, overlaps and stops with the second intermediate body, thereby achieving the function of the armrest opening 90 degrees. Of course, the number of intermediate bodies 221 can also be other numbers, such as four, and the armrest can still be opened 90 degrees.

[0041] Preferably, the number of the aforementioned hinged devices 2 is two, the number of the first hinged portions is two and they are coaxially arranged, and the two first hinged portions are respectively connected to one hinged device 2. It is understood that, in general, the rotating hinged arm 1 includes a body, a connecting arm is formed on the body, and the first hinged portion is provided on the connecting arm. Therefore, the number of the two first hinged portions and their coaxial arrangement can be such that the connecting arm includes a first connecting arm and a second connecting arm, the first connecting arm and the second connecting arm are respectively formed on opposite sides of the body, one first hinged portion is provided on the first connecting arm, and the other first hinged portion is provided on the second connecting arm. The two first hinged portions are respectively connected to one hinged device 2 in the manner described above, that is, both are connected via the shaft 231 of the hinged device 2. In this case, the two hinged devices 2 can be coaxially connected to opposite sides of the rotating hinged arm 1 via their two shafts 231, thereby achieving structural stability. Of course, the arrangement can be adjusted, such as forming the first connecting arm and the second connecting arm in the middle of the body.

[0042] Possibly, the armrest further includes a folding structure 8, which includes a plurality of shielding covers. The folding structure 8 is configured such that the shielding cover on one side is connected to the first section 711 forming the first notch 71, and the shielding cover on the other side is connected to the second section 611 forming the second notch 61. When the rotating hinged arm 1 rotates to the second position, the plurality of shielding covers unfold and overlap with each other and together with the armrest seat 7 and the armrest cover 6 cover the armrest hinge structure 100. That is, when viewed from the inside of the armrest, the folding structure 8 can cover the unfolded armrest hinge structure 100 together with the bottom of the armrest cover 6 and the top of the armrest seat 7. When the rotating hinged arm 1 rotates to the first position, the overlapping portions of the plurality of shielding covers disengage from each other and the plurality of shielding covers fold together. For ease of explanation, hereinafter, the shielding cover connected to the first section 711 of the present invention is referred to as the first shielding cover 81, and the shielding cover connected to the second section 611 is referred to as the second shielding cover 82.

[0043] As a possible implementation method, when the rotating hinge arm 1 rotates to the second position, the first shielding cover 81 overlaps the inner wall of the armrest seat 7 at the first slot 71, and the second shielding cover 82 overlaps the inner wall of the armrest cover 6 at the second slot 61. When the rotating hinge arm 1 rotates to the first position, the folding structure 8 is disengaged from the overlapping parts of the inner wall of the armrest seat 7 and the inner wall of the armrest cover 6.

[0044] Specifically, the overlapping method can be achieved by overlapping by flanges. For example, two flanges are formed on the side of the first shielding cover 81 facing the other shielding covers, and flanges are formed on the opposite sides of the other shielding covers. When the rotating hinge arm 1 rotates to the second position, one of the flanges of the first shielding cover 81 overlaps the inner wall of the armrest seat 7, and each shielding cover is overlapped by the corresponding flange. One of the flanges of the second shielding cover 82 overlaps the inner wall of the armrest cover 6, so that when the armrest is opened, the armrest is opened by the armrest. Internally, the folding structure 8 can cover the unfolded armrest hinge structure 100 together with the bottom of the armrest cover 6 and the top of the armrest seat 7. When the rotating hinge arm 1 rotates to the first position, the folding structure 8 is disengaged from the overlapping portion of the inner wall of the armrest seat 7 and the inner wall of the armrest cover 6, and the overlapping portions of the multiple shielding covers are disengaged from each other and the multiple shielding covers are folded together. The specific arrangement includes various ways, such as, the first shielding cover 81 can be in contact connection with the rotating hinge arm 1 and the first section 711, that is, the first shielding cover 8 1 is clamped between the rotating hinge arm 1 and the first section 711, and can move between the rotating hinge arm 1 and the first section 711 under the action of a certain force. Of course, the above-mentioned first shielding cover 81 is in contact with the rotating hinge arm 1, and can also be replaced by a first shielding cover 81 and a support member provided on the armrest seat 7 or the armrest cover 6. Contact connection, etc., to prevent the first shielding cover 81 from falling off when the rotating hinge rotates to the first position, and the second shielding cover 82 and the second section 611 can also be in contact. Touch connection, so that when multiple shielding covers are folded together, the multiple shielding covers can be abutted against each other. Preferably, at this time, the two ends of the second shielding cover 82 and the two ends of the shielding cover between the first shielding cover 81 and the second shielding cover 82 can respectively abut against the inner wall of the armrest cover 6 and the rotating hinge arm 1. Less preferably, at this time, the two ends of the second shielding cover 82 and the two ends of the shielding cover between the first shielding cover 81 and the second shielding cover 82 can respectively abut against the outer wall of the armrest seat 7 and the rotating hinge arm 1.

[0045] Alternatively, the arrangement in which the first shielding cover 81 overlaps the inner wall of the armrest base 7 at the first notch 71 and the second shielding cover 82 overlaps the inner wall of the armrest cover 6 at the second notch 61 can be replaced by: the end of the first shielding cover 81 is fixedly connected to the fixed hinge arm 21, and the end of the second shielding cover 82 is fixedly connected to the rotating hinge arm 1. In this case, the connection between the first shielding cover and the first section 711 can be either a fixed connection or a contact connection, and the connection between the second shielding cover and the second section 611 can similarly be either a fixed connection or a contact connection. As long as the plurality of shielding covers can unfold and overlap with each other when the rotating hinge arm 1 rotates to the second position, and together with the armrest base 7 and the armrest cover 6, cover the armrest hinge structure 100, and the overlapping portions of the plurality of shielding covers can disengage from each other and fold together when the rotating hinge arm 1 rotates to the first position, the arrangement falls within the scope of protection of the present invention.

[0046] Of course, the above-mentioned overlapping method can also be replaced by overlapping through a locking hook and a locking ring, wherein the locking hook can be inserted into the locking ring, at which time the locking ring and the locking hook are overlapped and abutted, and the locking hook can also be released from the locking ring.

[0047] The working process of the above-mentioned setting method includes: in the movement stroke of opening the armrest cover 6, the folding structure 8 is opened in sections, and the folding structures 8 are overlapped with each other; in the movement stroke of closing the armrest cover 6, the folding structure 8 can be overlapped together by relying on the action of force (gravity, thrust of rotating hinged arm 1, etc.).

[0048] The provision of the folding structure 8 can reduce the internal space occupied by the armrest seat 7 and the armrest cover 6, which is beneficial to the arrangement of related products.

[0049] Preferably, the number of shielding covers is 3, so that when the number of intermediate bodies 221 is two, the folding structure 8 can be divided into three layers and flipped accordingly, thereby covering the armrest hinge structure 100 and occupying very little internal space of the armrest.

[0050] By jointly disposing the armrest hinge structure 100 and the folding structure 8, the space occupied by the rotating articulated arm 1 in the entire movement range can be further reduced, which greatly facilitates the layout of the product.

[0051] The armrest hinge structure 100 may be an armrest hinge structure on a sub-instrument panel of a vehicle, or an armrest hinge structure at a rear seat of a vehicle.

[0052] It should be noted that the above-mentioned embodiments are only used to illustrate the principles of the present invention and are not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above-mentioned embodiments so that the present invention can be applied to more specific application scenarios.

[0053] For example, as an alternative embodiment, although the present invention is introduced as a first hinge part rotatably connected to the second hinge part through the shaft 231, this is not intended to limit the scope of protection of the present invention. For example, the first hinge part and the second hinge part can be rotatably connected through a gear assembly, etc., which does not deviate from the principles of the present invention and is within the scope of protection of the present invention.

[0054] For example, as an alternative embodiment, although the present invention is described in that when the rotating articulated arm 1 rotates to the second position, the connecting member 22 overlaps the rotating articulated arm 1 and the fixed articulated arm 21; when the rotating articulated arm 1 rotates to the first position, the overlapping parts of the connecting member 22, the rotating articulated arm 1 and the fixed articulated arm 21 are disengaged from each other, but this is not intended to limit the scope of protection of the present invention. The setting method can be adjusted, such as the rotating articulated arm 1 and the fixed articulated arm 21 can be connected by a corrugated rubber part, so that when the rotating articulated arm 1 rotates to the first position, the rotating articulated arm 1, the connecting member 22, and the fixed articulated arm 21 are overlapped together, and when the rotating articulated arm 1 rotates to the second position, the rotating articulated arm 1, the connecting member 22, and the fixed articulated arm 21 are unfolded. These do not deviate from the principles of the present invention and are within the scope of protection of the present invention.

[0055] For example, as an alternative embodiment, although the connecting member 22 of the present invention is introduced as including multiple intermediate bodies 221, its setting method is not unique. For example, it can be only one intermediate body 221, etc. These do not deviate from the principles of the present invention and are within the scope of protection of the present invention.

[0056] For example, as an alternative embodiment, although the shaft body 231 of the present invention is introduced as the screw portion of the bolt 23, this is not intended to limit the scope of protection of the present invention. For example, the shaft body can be only a shaft body and have a shoulder, etc., which does not deviate from the principles of the present invention and is within the scope of protection of the present invention.

[0057] In addition, the present invention also provides a vehicle, which includes the armrest described in any one of the above embodiments. After the vehicle has the armrest, it is beneficial to the arrangement of parts in the interior space of the vehicle.

[0058] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
