The backrest 4 is composed of a backrest framework 4a and a backrest panel 4b, the backrest framework 4a and the backrest panel 4b are fixedly bonded or fixedly connected through screws, and the seat panel 3b and the backrest panel 4b can be made of plastic plates or glass fiber reinforced plastic plates and the like.
The seat framework 1 is composed of a plurality of vertical beams 1a and a transverse framework body 1b, the transverse framework body 1b is of a framework structure formed by welding a plurality of cross beams and longitudinal beams, the plurality of vertical beams 1a are parallelly installed on one side of the transverse framework body 1b, the vertical beams 1a downwards extend to the lower side of the transverse framework body 1b, and the vertical beams 1a and the transverse framework body 1b are integrally of a T-shaped structure, so that the overall structural strength of the seat framework 1 is improved, and the overall bearing capacity of the seat framework 1 is improved. The vertical beams 1a and the transverse frame body 1b are connected in a welding mode or can be fixedly connected together through bolts, and the vertical beams 1a are fixedly connected with the wall plate 2 through bolts 5. The transverse frame body 1b is arranged above the equipment cabinet 6, and the maintenance personnel can conveniently overhaul the equipment in the equipment cabinet 6 after the chair surface 3 is turned over.
In this embodiment, the backrest 4 is fixed on the top end of the seat frame 1, the backrest frame 4a has two mounting edges 4c, the two mounting edges 4c are perpendicular to each other, one mounting edge 4c extends downward, the other mounting edge 4c horizontally extends, and the side surfaces and the top surface of the upright beam 1a are fixedly connected through the bolts 7 respectively, so that the backrest 4 and the seat frame 1 are fixed firmly. The top of the backrest 4 is closely attached to the wallboard 2, so that no installation gap exists between the backrest 4 and the wallboard 2, and the improvement of the interior quality of the vehicle is facilitated. In order to further improve the interior effect, a rubber strip 8 is further arranged between the top of the backrest 4 and the wall plate 2, when the backrest 4 is installed, the backrest 4 can be tightly pressed by the rubber strip 8, the manufacturing errors of the wall plate 2 and the backrest 4 are absorbed by the rubber strip 8, and then the backrest 4 and the wall plate 2 are ensured to be tightly attached without gaps.
In this embodiment, the seat 3 is connected to the seat frame 1 through the turnover mechanism 9, and the turnover mechanism 9 is used to drive the seat 3 to turn upwards when the equipment in the equipment cabinet 6 needs to be maintained, and turn the seat 3 downwards to a normal seat state after maintenance. The turnover mechanism 9 is arranged in two groups and is arranged on two sides of the seat body, so that the seat body can be stably turned over no matter in a single seat structure or in a plurality of connected seat structures.
Specifically, the turnover mechanism 9 includes a rotating arm 10, a rotating shaft 11 and a gas spring 12, one end of the rotating arm 10 is fixed on the vertical beam 1a of the seat frame 1, the other end of the rotating arm 10 is rotatably connected with the seat frame 3a of the seat 3 through the rotating shaft 11, in this embodiment, it is preferable that the connection point between the rotating arm 10 and the seat 3 is located at the top of the seat 3, that is, the rotating shaft 11 is installed at the top of the seat 3, and the whole seat 3 performs a circular motion around the rotating shaft 11 to realize the up-and-down turnover. The length of the rotating arm 10 is such that the position of the rotating shaft 11 does not protrude from the position of the outer surface of the backrest panel 4b of the backrest 4, so as to reduce the radius of rotation of the seat 3 and reduce the space occupied by the seat 3 during rotation.
The bottom end of the gas spring 12 is rotatably connected with a mounting seat 13, the mounting seat 13 is welded or fixedly connected with the transverse frame body 1b of the seat framework 1 through a bolt, and the top of the gas spring 12 is rotatably connected with the seat framework 3a of the seat 3. In this embodiment, preferably, the connection point 14 of the gas spring 12 and the seat 3 is located at the inner side below the connection point of the rotating arm 10 and the seat 3, i.e. the rotation shaft 11, when the seat 3 is turned downwards, i.e. the connection point 14 of the gas spring 12 and the seat 3 is located at the side of the rotation shaft 11 facing the wall plate 2 in the vertical direction, so that when the seat 3 is turned downwards to the normal position, after the connection point 14 at the upper part of the gas spring 12 is turned to the lowest point, the seat 3 will continue to be turned downwards under the action of the gas spring 12, so that the seat 3 is pressed against the seat frame 1, and the seat 3 can be further stabilized at the normal position by the gas spring 12.
A fixing plate 20 is further installed on the top of the seat frame 3a, the fixing plate 20 and the seat frame 3a are connected by welding or by bolt fitting, the rotating shaft 11 is installed on the fixing plate 20 and the seat frame 3a, a protrusion 21 protrudes from the bottom of the fixing plate 20 towards the wall plate 2, and the connection point 14 on the top of the gas spring 12 is arranged on the protrusion 21, so that the connection point 14 is located on the inner side of the rotating shaft 11 when the seat 3 is in the normal position. The distance between the connection point 14 and the rotation axis 11 is the minimum distance that the gas spring 12 pushes the seat 3 to rotate around the rotation axis 11.
Be provided with backstop structure between the bottom of back 4 and the top of seat 3, backstop structure is including setting up the first hem 15 of buckling to wallboard 2 direction in back 4 bottom to and set up and buckle into L shape second hem 16 and third hem 17 to wallboard 2 direction in succession at the top of seat 3, third hem 17 perpendicular to second hem 16 upwards stretches out, third hem 17 offsets with first hem 15 and leans on when seat 3 overturns to normal position downwards and realizes the backstop cooperation.
The swivel arm 10 has a portion 18 which is bent in the direction of the seat 3, so that the second and third folds 16, 17 do not limit the maximum angle of rotation of the seat 3 due to a collision with the swivel arm 10 when the seat 3 is turned up into the open position, the second and third folds 16, 17 being accommodated in the bent portion 18.
A pressing lock 19 capable of locking the seat surface 3 is further installed on the other side of the horizontal frame body 1 b. When the seat 3 is in a normal closed state, the seat 3 is locked with the seat frame 1 through the pressing lock 19. The front edge 22 of the seat panel 3b has a portion extending out of the seat frame 3a and is bent downward, which is not only beneficial to increase the comfort level of passengers when sitting, but also can effectively shield the pressing lock 19 installed on the transverse frame body 1b, and is beneficial to the operation of the pressing lock 19 by operators due to the large installation space.
As shown in fig. 2 and 3, when the seat 3 is opened, the pressing lock 19 is opened first, the front edge of the hand-held seat 3 is lifted upward, and when the upper connecting point 14 of the gas spring 12 rotates to the lowest point, the seat 3 is released, and the seat 3 will slowly turn upward under the action of the gas spring 12 until the end of the travel. When the seat is closed, the seat 3 is slightly pressed downwards to compress the stay bar of the gas spring 12, when the upper connecting point 14 of the gas spring 12 rotates to the lowest point, the seat 3 continuously turns downwards under the action of the gas spring 12 to press the seat framework 1, and finally the pressing lock 19 is locked.
The seat is simple and compact in structure, stable and reliable in operation, light in weight, convenient and fast to use, and the seat framework 1 and the seat surface 3 do not need to be disassembled during installation. In addition, the chair seat 3 makes circular motion around the upper rotating shaft 11, the track is accurate, and the chair seat is stable and does not shake in the overturning process. After locking, the gas spring 12 enables the seat surface 3 to be tightly pressed on the seat framework 1, and the fixing is reliable. Meanwhile, the backrest 4 is separated from the seat surface 3, the backrest 4 is not turned over and is closely attached to the wallboard 2 without a gap, and the interior quality of the vehicle is improved.
