Description

Technical Field

[0001] The invention relates to the technical field of automobile parts, and in particular to a connector for an automobile armrest. Background Art

[0002] Currently, the back seats of cars usually have multiple functions, such as two or three, such as cars that are mainly used to carry passengers, such as vans, minibuses, etc.

[0003] Among them, in order to provide a hand-held fulcrum or protect personal privacy, armrests are usually arranged between seats, and in order to facilitate passengers to get on and off the seats, the armrests are usually arranged to be rotatable, that is, when a passenger wants to sit on the inner seat, he first needs to turn the armrest upwards and then move it over. If the armrest is needed later, the armrest can be turned downward to a horizontal or slightly tilted or slightly downward state.

[0004] The mutual rotation between the armrest and the backrest is usually achieved through a connector, which usually allows the armrest to rotate upward and downward, and also to stay at a desired angle, such as the aforementioned "horizontal or slightly tilted or slightly downward" state. Summary of the invention

When the positioning body is meshed with the locking ring, the driving part is attached to the rotating part, and the locking part is attached to the locking part. The second connecting shell can be rotated in the ω direction by the driving part to drive the rotating part and the positioning body to rotate. When the second connecting shell is rotated in the -ω direction, the locking part is pressed against the locking part.

[0012] The present invention is further configured as follows: the active slot is located between the driven slot and the center of the first connecting shell.

[0013] The present invention is further configured as follows: two rotating columns are provided on the first connecting shell, and the two rotating columns are symmetrically distributed on both sides of the center of the first connecting shell.

[0014] The present invention is further configured as follows: it also includes a connecting column, and the two ends of the connecting column are respectively provided with a first anti-detachment portion and a second anti-detachment portion, the first anti-detachment portion abuts against the outer side of the first connecting shell, and the second anti-detachment portion abuts against the outer side of the second connecting shell, the first connecting shell is fixedly connected to the connecting column, and the second connecting shell and the unlocking plate are both rotatably connected to the connecting column.

[0015] The present invention is further configured as follows: the connecting column comprises an anti-rotation portion, both sides of the anti-rotation portion are planar, and the anti-rotation portion is cooperatively connected with the first connecting shell.

[0016] The present invention is further configured as follows: the connecting column also includes a cylindrical movable part and a drag reduction part, the movable part is located between the drag reduction part and the anti-rotation part, and the diameter of the movable part is larger than the diameter of the drag reduction part, and a connecting bearing is arranged between the outer wall of the drag reduction part and the second connecting shell.

[0017] The present invention is further configured as follows: two sides of the connecting bearing are respectively attached to the movable portion and the second anti-slip portion.

[0018] The present invention is further configured as follows: the middle portion of the elastic member is annularly sleeved on the outer wall of the anti-rotation portion and matched with the shape of the outer wall of the anti-rotation portion, the edge of which abuts against the positioning body, the end of the elastic member abutting against the positioning body is L-shaped, and an arc-shaped anti-slip groove is provided on one side of the positioning body where the elastic member fits, and there is line contact between the elastic member and the inner wall of the anti-slip groove.

[0019] The present invention is further configured as follows: the diameter of the first connecting shell is greater than the diameter of the second connecting shell, a circle of anti-slip ring is provided on the edge of the first connecting shell, a corrugated washer is provided on the inner wall of the anti-slip ring, and the locking ring is movably fitted to the corrugated washer.

[0020] The beneficial effects of the present invention are as follows: first, when the connector is in use, the first connecting shell is fixedly connected to the backrest, while the armrest is fixedly connected to the second connecting shell. When adjusting the armrest upward, it is only necessary to directly rotate the armrest upward. At this time, the second connecting shell is driven by the armrest to rotate upward, so that the locking tooth unit also has a tendency to rotate. At this time, the locking tooth unit is in contact with the rotating part of the positioning body through its driving part. Since the driving part and the rotating part are both in a small angle shape, the driving part can drive the rotation to rotate in a direction close to the center of the first connecting shell until a locking tooth unit is separated from a positioning tooth unit, and the positioning tooth unit is meshed with the next locking tooth unit again, but the next locking tooth unit can also drive the positioning tooth unit to rotate, so in this In terms of direction, the armrest can be considered to have no resistance (it means that it can be directly rotated, not that there is no operational resistance to rotation); when it is rotated to a certain angle, such as a horizontal or slightly upward tilted state, the weight of the armrest makes the armrest and the second connecting shell have a tendency to rotate downward. At this time, the locking portion on the locking ring contacts the stop portion, but because the stop portion and the locking portion both have a large angle, the locking tooth unit cannot drive the positioning tooth unit to rotate. Therefore, the positioning body restricts the locking ring from rotating in this direction, that is, the armrest cannot continue to rotate downward, so the armrest is positioned and can be used normally. When the armrest needs to be returned to the lowest position, the cylinder unlocking structure only needs to unlock the positioning body so that the positioning body is separated from the locking ring. In this way, the locking ring and the second connecting shell can be directly rotated to the most original position, waiting for the next use.

[0021] In the process of turning the armrest upward and using it, the armrest can be turned upward directly without any other operations. After the armrest is operated to the appropriate position, the armrest can be released. Under the action of its own gravity and the characteristics of the positioning body and the locking ring shape, the armrest can maintain a stable position without the need for fixation, which is simple and convenient. In addition, since each locking tooth unit can be the position where the armrest stops, the armrest can have many use angles when it is actually used, that is, the armrest can be used at an angle downward, horizontally, or slightly upward. At the same time, the armrest can be fine-tuned during actual use so that the angle of the armrest can be adapted to certain requirements and the use effect is better.

The active groove 12 is located between the driven groove 13 and the center of the first connection shell 1. Two rotating columns 3 are arranged on the first connection shell 1, and the two rotating columns 3 are symmetrically distributed on both sides of the center of the first connection shell 1.

[0046] It also includes a connecting column 14, and the two ends of the connecting column 14 are respectively provided with a first anti-detachment portion 15 and a second anti-detachment portion 16, the first anti-detachment portion 15 abuts against the outer side of the first connecting shell 1, and the second anti-detachment portion 16 abuts against the outer side of the second connecting shell 2, the first connecting shell 1 is fixedly connected to the connecting column 14, and the second connecting shell 2 and the unlocking plate 9 are both rotatably connected to the connecting column 14.

[0047] The connecting column 14 includes an anti-rotation portion 14a, both sides of which are planar, and the anti-rotation portion 14a is cooperatively connected with the first connecting shell 1. The connecting column 14 also includes a cylindrical movable portion 14b and a drag reduction portion 14c, the movable portion 14b is located between the drag reduction portion 14c and the anti-rotation portion 14a, and the diameter of the movable portion 14b is larger than the diameter of the drag reduction portion 14c, and a connecting bearing 17 is provided between the outer wall of the drag reduction portion 14c and the second connecting shell 2. The two sides of the connecting bearing 17 are respectively attached to the movable portion 14b and the second anti-detachment portion 16.

[0048] The middle part of the elastic member 5 is annularly sleeved on the outer wall of the anti-rotation part 14a, and matches the shape of the outer wall of the anti-rotation part 14a, and the edge abuts against the positioning body 4. The end of the elastic member 5 that abuts against the positioning body 4 is L-shaped, and an arc-shaped anti-slip groove 18 is provided on the side where the positioning body 4 and the elastic member 5 are in contact, and there is line contact between the elastic member 5 and the inner wall of the anti-slip groove 18.

[0049] The diameter of the first connecting shell 1 is greater than that of the second connecting shell 2 . The edge of the first connecting shell 1 is provided with a circle of anti-slip ring 19 . The inner wall of the anti-slip ring 19 is provided with a corrugated washer 20 . The locking ring 6 is movably fitted to the corrugated washer 20 .

[0050] The present invention provides a connector for an automobile armrest. First, when the connector is in use, the first connection shell 1 is fixedly connected to the backrest, and the armrest is fixedly connected to the second connection shell 2. When adjusting the armrest upward, it is only necessary to directly rotate the armrest upward. At this time, the second connection shell 2 is driven by the armrest to rotate upward, so that the locking tooth unit 7 also has a tendency to rotate. At this time, the locking tooth unit 7 is in contact with the rotating part 8a of the positioning body 4 through its driving part 7a. Since the driving part 7a and the rotating part 8a are both in a small angle shape, the driving part 7a can drive the rotation to rotate in a direction close to the center of the first connection shell 1, until a locking tooth unit 7 is separated from a positioning tooth unit 8, and the positioning tooth unit 8 is meshed with the next locking tooth unit 7 again, but the next locking tooth unit 7 can also drive the positioning tooth unit 8 to rotate. In this direction, the armrest can be considered to have no resistance (it means that it can be directly rotated, not that there is no operational resistance to the rotation); when it is rotated to a certain angle, such as a horizontal or slightly upward tilted state, the weight of the armrest makes the armrest and the second connecting shell 2 have a tendency to rotate downward, and the locking portion 7b on the locking ring 6 contacts the stop portion 8b, but because the stop portion 8b and the locking portion 7b both have a large angle, the locking tooth unit 7 cannot drive the positioning tooth unit 8 to rotate, so the positioning body 4 limits the rotation of the locking ring 6 in this direction, that is, the armrest cannot continue to rotate downward, so the positioning of the armrest is achieved, and the armrest can be used normally. When the armrest needs to be returned to the lowest position, the cylinder unlocking structure only needs to unlock the positioning body 4, so that the positioning body 4 is separated from the locking ring 6, so that the locking ring 6 and the second connecting shell 2 can be directly rotated to the most original position, waiting for the next use.

[0051] In the process of turning the armrest upward and using it, the armrest can be turned upward directly without any other operations. After the armrest is operated to a suitable position, the armrest can be released. Under the action of its own gravity and the characteristics of the shape of the positioning body 4 and the locking ring 6, the armrest can maintain a stable position without the need for fixing, which is simple and convenient. In addition, since each locking tooth unit 7 can be the position where the armrest stops, the armrest can have many use angles when it is actually used, that is, the armrest can be used at an angle downward, horizontally, or slightly upward. At the same time, the armrest can also be fine-tuned when it is actually used, so that the angle of the armrest can be adapted to certain requirements and the use effect is better.

[0052] In actual use, the connector includes four processes, namely the first process, the second process, the third process and the fourth process, and the angle changes of the armrest in the four processes are from 0°-A°, A°-B°, B°-A° and A°-0°, respectively, wherein 0° indicates that the armrest is at the lowest angle, usually parallel to the backrest, and the bottom of the armrest is lower than the angle of the connector, A° indicates the maximum angle of normal use of the armrest, usually horizontal or slightly tilted upward (ie 45° or 60°), and then B° indicates the maximum angle at which the armrest can be rotated upward, usually parallel to the backrest, and the top of the armrest is higher than the connector (of course, the specific angles of 0°, A° and B° are not the protection scope required by this application, and also indicate that the scheme of this application is not limited to these angles, and the listed angles are only for detailed description of each process). The actions and behaviors of the four processes are as follows, with the attached Figure 5 The state in the figure is shown in Figure 1, and the active slot 12 and the driven slot 13 in the upper right corner are taken as an example:

[0053] First process (0°-A°): the active body 10 is located at the leftmost side of the active groove 12, and the driven body 11 is located in the first groove portion 13a. At this time, the positioning gear unit 8 can automatically lock the locking ring 6. Then, the first connecting shell 1 is stationary, and the handrail drives the second connecting shell 2 to rotate clockwise;

[0054] The second process (A°-B°): the active body 10 rotates to the lower right corner of the active groove 12, and the active body 10 drives the unlocking plate 9 to rotate. When the unlocking plate 9 rotates, the driven body 11 slides from the first groove portion 13a into the second groove portion 13b (the elastic member 5 is originally in a compressed state, but the compression state is greater at this time). At this time, the positioning tooth unit 8 is separated from the locking tooth unit 7, and the armrest and the locking ring 6 are not affected by external forces. The armrest can be rotated freely until the armrest rotates to the maximum angle. At this time, the driven body 11 hits the lower right corner of the second groove portion 13b. Since the unlocking plate 9 cannot continue to rotate, the armrest and the second connecting shell 2 cannot continue to rotate;

[0055] The third process (B°-A°): the armrest is rotated in the reverse direction, that is, the armrest is rotated counterclockwise. At this time, since the active groove 12 is in an empty state, the rotation of the active body 10 is not affected, and the unlocking plate 9 will not be driven to rotate (there is a certain resistance between the unlocking plate 9 and the rotating part 8a, which can prevent the unlocking plate 9 from rotating at will); at the same time, in this process, since the driven body 11 is located in the second groove 13b, the positioning tooth unit 8 and the locking tooth unit 7 are in a separated state, and the fixed armrest is not subject to resistance when rotating in this direction (i.e. downward);

[0056] The fourth process (A°-0°): the active body 10 rotates until it contacts the upper left corner of the active groove 12, and starts to drive the unlocking plate 9 to rotate counterclockwise. However, at this time, since the driven body 11 is still located in the second groove portion 13b, the armrest and the second connecting shell 2 are still not subject to resistance and can rotate normally; until the driven body 11 enters the first groove portion 13a, under the elastic force of the elastic member 5, the positioning body 4 rotates outward, so that the driven body 11 enters the first groove portion 13a, and at the same time the positioning tooth unit 8 and the locking tooth unit 7, the locking portion 8b and the locking portion 7b are pressed tightly, preventing the second connecting shell 2 and the armrest from continuing to rotate. At this time, the armrest returns to its original position.

[0057] From the above operation process, it can be seen that the locking and unlocking of the armrest are achieved spontaneously by relying on the shape and structure inside the connector, without the need for manual adjustment of the operating handle. The operation is less difficult and more convenient; especially when returning the armrest to its original position, you only need to turn the armrest.

[0058] There are two rotating columns 3, so there are also two positioning bodies 4, active grooves 12, driven grooves 13, active bodies 10, driven bodies 11, etc., and the orientations of the two positioning bodies 4, the two active grooves 12 and the two driven grooves 13 are the same. Therefore, in actual use, the two positioning bodies 4 and the rotating columns 3 can transmit and withstand the force between the first connecting shell 1 and the second connecting shell 2, thereby protecting the connector and extending the service life of the connector.

[0059] During the actual assembly, the first anti-slip portion 15 and the second anti-slip portion 16 are connected to the outer sides of the first connection shell 1 and the second connection shell 2 respectively by riveting, so firstly, the first anti-slip portion 15 and the second anti-slip portion 16 can prevent the first connection shell 1 and the second connection shell 2 from separating from each other, and at the same time, the first connection shell 1 and the second connection shell 2 can have the required mutual tightening force, one of the benefits of which is that it can prevent dust from entering, and secondly, it can make the second connection shell 2 and the corrugated washer 20 have a certain resistance, so when the handrail is rotated to the highest angle, the handrail and the second connection shell 2 can be subject to the resistance of the corrugated washer 20, and will not rotate spontaneously easily, but can only rotate the handrail when it needs to be rotated manually. At the same time, the anti-slip ring 19 can also limit and block the corrugated washer 20, so that the corrugated washer 20 can stably maintain its position, and the stability of use is also higher; and the anti-slip ring 19 and the corrugated washer 20 can further prevent dust and water from entering, slow down the rusting speed, and extend the service life.

[0060] Among them, both sides of the anti-rotation part 14a are flat, and the overall cross-section is elliptical, so first, the connecting column 14 and the first connecting shell 1 cannot rotate, but the movable part 14b and the drag reduction part 14c are both cylindrical, so the unlocking plate 9 and the second connecting shell 2 can rotate relative to the connecting column 14.

[0061] During use, the middle of the elastic member 5 is attached to the outer wall of the anti-rotation portion 14a, so the elastic member 5 itself cannot rotate, but the end of the elastic member 5 is in contact with the positioning body 4, so when the positioning body 4 rotates or moves, the end of the elastic member 5 can be driven to deform. That is, when the positioning body 4 is driven by the driving portion 7a, or transitions from the first groove portion 13a to the second groove portion 13b, the end of the elastic member 5 will be elastically deformed, and the elastic member 5 also applies a force to the positioning body 4 to continuously rotate outward, so that the locking tooth unit 7 and the positioning tooth unit 8 can be normally meshed, and can normally enter the first groove portion 13a from the second groove portion 13b.

[0062] The end of the elastic member 5 is L-shaped, and there is line contact between the elastic member 5 and the positioning body 4; because the positioning body 4 is rotating, the positioning body 4 and the end of the elastic member 5 are relatively sliding, so the two are prone to wear, but because the elastic member 5 is fine, it is more likely to be damaged and cannot function normally; so by setting the end of the elastic member 5 to have a longer length (i.e. L-shaped), the wear of the elastic member 5 can be evened out, the wear rate is reduced, and the service life of the connector is extended. At the same time, since the positioning body 4 has a concave anti-slip groove 18, it can also better prevent the elastic member 5 and the positioning body 4 from separating from each other, so that the elastic member 5 can stably act on the positioning body 4, and the positioning body 4 can also stably act on the locking ring 6.

[0063] There is a connecting bearing 17 between the second connecting shell 2 and the drag reduction groove, so the wear between the connecting column 14 and the second connecting shell 2 can be reduced, the service life can be extended, and the noise can be reduced, so as to improve the use effect and quality; since there is a connecting bearing 17 between the connecting column 14 and the second connecting shell 2, the resistance between the connecting column 14 and the second connecting shell 2 is small, so that when the handrail is rotated to the highest position, it can maintain its position stable and will not spontaneously rotate to the lowest angle, the first anti-slip part 15 and the second anti-slip part 16 need to have a certain pressure between the first connecting shell 1 and the second connecting shell 2 respectively, so as to maintain the effect of the handrail normally. The two sides of the connecting bearing 17 are respectively against the ends of the second anti-slip part 16 and the movable part 14b, so the position stability of the connecting bearing 17 is also higher, so that the integrity of the entire connector is also stronger.

[0064] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0065] The above description is only a description of the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention. Any changes or modifications made by a person skilled in the art in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
