Description

Technical Field

[0001] The invention belongs to the technical field of automobile seats, and in particular relates to a foldable automobile seat table top. Background Art

[0002] Many existing car models are equipped with table boards on car seats, but most of them are installed on the backrests of the front seats. Specifically, the table boards are installed on the backrests of the front seats through an upper hinge structure. When in use, the table boards are pulled upward and rotated around the upper hinge end to a horizontal state.

[0003] In addition, there is also a solution of installing a table top on the armrest, for example, the car seat provided in document CN206968475U includes: a seat frame, the seat frame includes an armrest portion, a backrest portion and a cushion portion, the armrest portion includes an armrest panel and an armrest cover assembly that are slidably connected or rotatably connected, the armrest panel is provided with a cup holder structure and / or a table top structure, when the armrest panel is provided with a table top structure, the table top structure can slide out of the armrest portion and rotate relative to the armrest portion, and the table top structure can slide into the armrest portion and lock with the armrest portion, and the table top structure adopts a pull-out telescopic structure.

[0004] However, the above-mentioned structure in which the table top is installed on the armrest has at least the following problems during use: the table top is too short. When the table top is extended, the right end of the table top is located on the left side of the vertical section where the passenger's seating centerline (and the seat H point) of the corresponding car seat is located, resulting in poor comfort and operating experience for the passenger when using the table top; due to the limitation of the width and space of the car seat, it is difficult to lengthen the table top as a whole and install it on the armrest; the operating steps of extending and storing the table top are relatively complicated. When extending the table top, it is necessary to first flip the table top and then pull it out. When storing the table top, it is necessary to first push the table top back and then flip it over. Summary of the invention

[0005] The object of the present invention is to provide a foldable automobile seat table top which has both good use comfort and simple operation without lengthening the table top itself.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution.

[0007] A foldable car seat table, including a foldable table assembly, which is connected to a seat armrest via an adjustable rotating mechanism; when the table assembly is in a horizontal storage state, the table assembly is just located on the seat armrest; when the table assembly is rotated counterclockwise from the horizontal storage state to a first extreme position, the table assembly extends and the right end of the table assembly is located on the right side of the vertical section where the center line of the car seat is located (i.e., the seat H point).

[0008] Furthermore, the adjustable rotating mechanism includes a rotating shaft, on which a first rotating plate and a second rotating plate are arranged, the second rotating plate is located above the first rotating plate, an arc hole is arranged on the first rotating plate, a linear hole is arranged on the second rotating plate, a movable pin assembly is passed through the arc hole and the linear hole, and the upper part of the movable pin assembly is also fixedly connected to the table board assembly; when the table board assembly rotates counterclockwise from a horizontal storage state, the first rotating plate and the second rotating plate both rotate counterclockwise around the rotating shaft, and the movable pin assembly simultaneously moves along the starting end of the arc hole and the linear hole to the end.

[0009] In the present invention, with the center of the rotation axis as the origin, the rotation range of the second rotating plate in the horizontal direction is 180°~360°, and the rotation range of the first rotating plate in the horizontal direction is 212.1°~8.5°.

[0010] In the present invention, when the table top assembly is in a horizontal storage state, the center of the movable pin assembly is located just to the left of the center of the rotation axis; when the movable pin assembly moves along the starting ends of the arc hole and the linear hole to the end at the same time, the center of the end portion of the arc hole and the center of the end portion of the linear hole are both located on the axis of the movable pin assembly, and the center of the movable pin assembly is located just to the right of the center of the rotation axis.

[0011] In order to eliminate abnormal noise during use and improve the stability when operating and using the table top, the movable pin assembly includes a column with three limiting cap bodies, and a plastic part and a bushing are sleeved on the column. The plastic part is located above the bushing, and the plastic part is located below the middle limiting cap body. The middle limiting cap body and the lower limiting cap body are used to install the first rotating plate and the second rotating plate. The first rotating plate is sleeved on the bushing, and the second rotating plate is sleeved on the plastic part. There is a gap between the first rotating plate and the second rotating plate; the middle limiting cap body and the upper limiting cap body are used to install the table top connecting piece.

[0012] Preferably, the diameter of the middle limit cap body is larger than the width of the linear hole, and the diameter of the lower limit cap body is larger than the width of the arc hole and the width of the linear hole.

[0013] In order to further improve the stability during the use of the table top, an elastic limit pin is arranged on the seat armrest and located outside the rotating shaft. The contact of the elastic limit pin is a spherical structure, and the contact of the elastic limit pin is higher than the bottom surface of the first rotating plate; when the contact of the elastic limit pin is subjected to a vertical downward force, the contact of the elastic limit pin can move downward to a position lower than the bottom surface of the first rotating plate, and the table top assembly can rotate horizontally at this time; after the force applied to the contact of the elastic limit pin is cancelled, the contact of the elastic limit pin is reset, and the table top assembly is limited by the elastic limit pin and cannot rotate horizontally.

[0014] Preferably, the outer contour of the first rotating plate has a first straight edge, a second straight edge and an arc-shaped edge, and the first straight edge is located opposite to the second straight edge; when the table top assembly is in a horizontal storage state, the first straight edge abuts against the contact of the elastic limit pin; when the table top assembly rotates to the first extreme position, the second straight edge abuts against the contact of the elastic limit pin.

[0015] Preferably, the table top assembly includes a flat plate and a folding plate hingedly connected to the flat plate, the flat plate is fixedly connected to the table top connector, and the folding plate can be folded from a horizontal state to an inclined state; the seat armrest is rotatably connected to the backrest frame, and the seat armrest can be folded to a horizontal state, and the seat armrest can also be stored.

[0016] Preferably, the ends of the arc-shaped hole and the linear hole are both semicircular structures.

[0017] Beneficial effects: The foldable car seat table provided by the present invention is not only comfortable to use, but also easy to operate. When the table assembly is rotated counterclockwise from the horizontal storage state to the first extreme position, the table assembly extends and the right end of the table assembly is located on the right side of the vertical section where the center line of the car seat is located, so that the passenger can use the table more conveniently and comfortably. The passenger can use the table naturally without turning sideways. When the table needs to be extended, it is only necessary to rotate the table assembly counterclockwise. When the table needs to be stored, it is only necessary to rotate the table assembly clockwise. Compared with the pull-out table structure, the operation steps are significantly reduced; the foldable car seat table provided by the present invention takes into account the comfort of use without lengthening the length of the table assembly itself, because the connection point between the table assembly and the rotating mechanism has been moved outward during the rotation of the table assembly, and the connection point is moved from the left side of the rotation center to the right side of the rotation center. In addition, the foldable car seat table of the present invention has no hollow part between the table top and the armrest, and there is no telescopic rod below the table top to interfere with the arm during use.
