Detailed Description
Exemplary embodiments of the present utility model will now be described with reference to the accompanying drawings, in which various details of the embodiments of the present utility model are included to facilitate understanding, and are to be considered merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the utility model. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Referring to fig. 1, 2 and 3, the present embodiment includes a foldable seat 10 including a seat cushion 20 and a seatback 30, the seat cushion 20 being provided with a seat cushion support 21, the seat 10 being provided with a seat support 11, one end of the seat support 11 being connected with the seat cushion support 21, the other end being connected with a chassis of the scooter; the seatback 30 is provided with a seatback support 31, and one end of the seatback support 31 is connected with the cushion support 21;
also included are a first link 40 and a second link 50, one end of the first link 40 being hinged to the second link 50, the other end being hinged to the seatback support 31, and one end of the second link 50 being hinged to the first link 40, the other end being hinged to the seat support 11. Through the structure of this embodiment, the cushion support member supports the cushion 20, the seat support member 11 supports the seat and is connected with the chassis of the scooter, the seatback support member 31 supports the seatback 30, the cushion support member and the seatback support member 31 are hinged through the first link 40 and the second link 50, preferably, the seat support member 11, the seatback support member 31, the first link 40 and the second link 50 form a parallelogram structure, and therefore, the cushion 20 and the seatback 30 can be simultaneously height-adjusted or folded and unfolded.
Referring again to fig. 1, 2 and 3, in one embodiment, the cushion support 21 further includes a chute 22, and the first link 40 and the second link 50 are connected by a hinge shaft that is slidable within the chute 22. In the present embodiment, the first link 40 connects the seatback support 31 and the seat cushion support, and is fixed in the slide groove 22 of the seat cushion support 21 so as to be linearly slidable, and the second link 50 connects the seat cushion support 21 and the seat support 11, and is fixed in the slide groove 22 of the seat cushion support 21 so as to be linearly slidable in the slide groove 22. Specifically, the first link 40 and the second link 50 are coaxially hinged by a hinge shaft that can slide in the chute 22.
In one embodiment, the hinge shaft further includes a locking structure that limits sliding of the hinge shaft. Specifically, when the hinge shaft slides to the leftmost side of the chute 22, the locking structure restricts the hinge shaft from sliding to the right, and the seat 10 is in the unfolded state, so that the user can take a seat. When the locking structure is not operated, the hinge shaft coaxially hinged with the first link 40 and the second link 50 is not limited, and the seat 10 starts to fold as the neutral effect starts to slide to the right side of the chute 22, and when the hinge shaft slides to the rightmost side of the chute 22, the seat 10 completes folding, and the dimension of the seat 10 in the height direction is minimum, so that the seat is convenient to store. Specifically, the locking structure may employ various locking devices, which are not described herein.
In one embodiment, the seat support 11 includes a front support frame 12 and a rear support frame 13 that are parallel to each other; one end of the front support frame 12 is hinged with the cushion 20, and the other end is hinged with the scooter; one end of the rear supporting frame 13 is hinged with the cushion 20, and the other end is hinged with the scooter. The front support frame 12 and the rear support frame 13 form parallel links so that the seat 10 is always parallel during folding.
In one embodiment, the back support 31 is connected to the rear support bracket 13. Specifically, the seatback support 31 and the rear support bracket 13 are fixed on the right side of the seat cushion support 21, and the seatback support 31 and the rear support bracket 13 realize coaxial rotation, with a simpler structure.
In one embodiment, the second link 50 is hinged at one end to the first link 40 and at the other end to the rear support bracket 13. Specifically, the three lines of the rear support bracket 13, the sliding groove 22 portion of the cushion support 21, and the second link 50 are closed-loop-travel triangles, if one end of the link in the sliding groove 22 is limited by the locking structure, the three sides of the triangle are determined, at this time, the angle of the seat support 11 is determined and stable, and the seat 10 can realize a stable riding function. Similarly, the three lines of the seat back support 31, the sliding groove 22 of the seat cushion support 21 and the first connecting rod 40 are closed-loop in a triangular stroke, if one end of the connecting rod in the sliding groove 22 is limited by the locking structure, the three sides of the triangle are determined, at this time, the angle of the seat support 11 is determined and stable, and the seat 10 can realize a stable riding function.
In one embodiment, the seatback 30 further includes an armrest 60, the armrest 60 being rotatably coupled to the seatback 30. Specifically, the armrests 60 are secured to the back support 31 and only rotate when the seat 10 is in the folded condition, without disassembly and without affecting the height of the folded seat 10.
In one embodiment, the seatback support 31 and the seat cushion support 21 range from 0 ° to 180 °. Specifically, the seatback support 31 is inclined obliquely rearward, and can give a sense of wrap to the user, and is shielded from both left and right, and is safer and more comfortable.
Referring to fig. 4 to 6, in a certain embodiment, trim 70 is provided on the cushion support 21, the seatback support 31, and the seat support 11. In particular, trim piece 70 can reduce the probability of a user being pinched during the folding process.
Referring again to fig. 4 to 6, in the embodiment of fig. 4 and 5, the seat 10 is in the unfolded state, in which the hinge shaft, to which the first link 40 and the second link 50 are coaxially hinged, is slid to the leftmost end of the slide slot 22 of the cushion support 21, in which the locking structure is in the operating state, restricting the hinge shaft from sliding to the right side, and in which the seat support 11, the cushion support 21, the seatback support 31, and the first link 40 and the second link 50 are all in the fixed angle state, in which the seat 10 is unfolded to sit.
When the user adjusts the height of the seat 10, the seat back 30 moves along with the seat cushion 20 by lifting the seat cushion 20, and the seat cushion 20 moves along with the seat back 30 by lifting the seat back 30. When the user operates the chair back 30, the chair is more labor-saving and can reduce bending, which is beneficial to the health of the user, especially in the situation that the scooter is used for middle-aged and elderly people.
With continued reference to fig. 6, when the seat 10 needs to be folded, the locking structure is set to be in a non-working state, and as the gravity of the seat 10 itself acts, the hinge shaft of the first link 40 and the second link 50 coaxially hinged to each other slides to the rightmost end of the sliding groove 22 of the support 21 of the seat cushion 20, so as to drive the seat support 11 and the seatback support 31 to fold, and the seat 10 is not ridable, so that the height is reduced and the seat is automatically folded. When the seat 10 needs to be unfolded again, only the seat back 30 or the seat cushion 20 needs to be lifted upwards, the seat back 30 and the seat cushion 20 are lifted in a linkage way, and when the hinge shafts of the first connecting rod 40 and the second connecting rod 50 slide to the leftmost side of the sliding groove 22, the hinge shaft is limited by the locking structure, so that the seat 10 is unfolded, and the riding function is realized.
The above embodiments do not limit the scope of the present utility model. It will be apparent to those skilled in the art that various modifications, combinations, sub-combinations and alternatives can occur depending upon design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included in the scope of the present utility model.
