[0031] like Figures 1 to 4As shown, one embodiment of the present invention provides a new type of vehicle seat, which includes a seat bucket 11, a seat cushion 12 and a rear guard bar 13; the rear guard bar 13 is located behind the seat bucket 11; the new type of vehicle seat also includes at least one set of flipping mechanisms 14; the seat cushion 12 is connected to the seat bucket 11 through the flipping mechanism 14 and the seat cushion 12 can be flipped toward the rear guard bar 13; the flipping mechanism 14 includes a first connecting rod 141 and a second connecting rod 142; both ends of the first connecting rod 141 and the second connecting rod 142 are rotatably connected to the seat bucket 11 and the seat cushion 12 respectively; the length of the first connecting rod 141 is smaller than the length of the second connecting rod 142, and the first connecting rod 141 and the second connecting rod 142 are arranged in sequence along the direction from the rear end of the seat bucket 11 to the rear end close to the seat bucket 11.

[0032] The new vehicle seat provided in this embodiment includes a seat tub 11, a seat cushion 12, a rear bumper 13, and a tilting mechanism 14. The rear bumper 13 is provided at the rear of the seat tub 11. When a user sits on the seat cushion 12, their back can rest against the bumper 13, improving comfort and safety. The rear bumper 13 is connected to the outer wall of the rear end of the seat tub 11. The two ends of the rear bumper 13 extend to the left and right ends of the seat tub 11 and are connected to the outer walls of the left and right ends of the seat tub 11, respectively, thereby forming a left bumper and a right bumper. The seat cushion 12 is arranged on the seat bucket 11 through a flipping mechanism 14, and under the action of the flipping mechanism 14, the front side of the seat cushion 12 can be flipped toward the direction close to the rear guard bar 13 to separate the seat cushion 12 from the seat bucket 11 and lift up the seat cushion 12, or the front side of the seat cushion 12 can be flipped toward the direction away from the rear guard bar 13 to connect the seat cushion 12 to the seat bucket 11 and restore the seat cushion 12; the front side of the seat cushion 12 is the side of the seat cushion 12 away from the seat bucket 11, and when in use, the user can sit on the front side of the seat cushion 12.

[0033] Furthermore, the above-mentioned flipping mechanism 14 includes a first connecting rod 141 and a second connecting rod 142. One end of the first connecting rod 141 is rotatably connected to the seat bucket 11, and the other end is rotatably connected to the seat cushion 12; one end of the second connecting rod 142 is rotatably connected to the seat bucket 11, and the other end is rotatably connected to the seat cushion 12. The length of the first connecting rod 141 is smaller than that of the second connecting rod 142, and the first connecting rod 141 is closer to the rear end of the seat bucket 11 than the second connecting rod 142; that is, in this embodiment, the first connecting rod 141, the second connecting rod 142, the seat bucket 11 and the seat cushion 12 together form a planar four-bar mechanism; when the seat cushion 12 is flipped, the first connecting rod 141 and the second connecting rod 142 are rotated. The end of the rod 142 away from the seat barrel 11 swings upward, so that the rear end of the seat cushion 12 can move forward a certain distance, so that the rear end of the seat cushion 12 is away from the rear guard bar 13, avoiding the rear end of the seat cushion 12 from conflicting with the rear guard bar 13. In this way, the user can flip the seat cushion 12 from the front of the new vehicle seat; accordingly, the seat cushion lock is also located at the front end of the new vehicle seat; with the new vehicle seat provided in this embodiment, the user can directly flip the seat cushion 12 in the front of the new vehicle seat without having to go around to the back. Compared with the existing technology, the operation is more convenient and the user experience is better.

[0034] In this embodiment, the first connecting rod 141 and the second connecting rod 142 are both sheet-like structures, and pin holes are respectively provided at both ends of the first connecting rod 141 and the second connecting rod 142. Both ends of the first connecting rod 141 and the second connecting rod 142 are rotatably connected to the seat barrel 11 and the seat cushion 12 through pins and pin holes.

[0035] The new vehicle seat provided by the embodiment of the present utility model is as follows Figures 1 to 4 As shown, a side edge of the second connecting rod 142 close to the seat cushion 12 is provided with an avoidance notch 143 , and a portion of the end of the first connecting rod 141 close to the seat cushion 12 is located in the avoidance notch 143 .

[0036] In this embodiment, when the first link 141 and the second link 142 are assembled, there is a conflict between the end of the first link 141 close to the seat cushion 12 and the end of the second link 142 close to the seat cushion 12. In order to avoid affecting the assembly between the first link 141 and the second link 142, an avoidance notch 143 is opened on the side of the end of the second link 142 close to the seat cushion 12 toward the first link 141, and the end of the first link 141 close to the seat cushion 12 is located in the above-mentioned avoidance notch 143.

[0037] The new vehicle seat provided by the embodiment of the present utility model is as follows Figures 1 to 4 As shown, at least one set of flipping mechanisms 14 also includes an elastic member 144; the two ends of the elastic member 144 are respectively connected to the seat bucket 11 and the seat cushion 12. When the seat cushion 12 is flipped toward the rear bumper 13, the elastic member 144 is in a stretched state and is used to limit the seat cushion 12 from resetting.

[0038] After the user lifts up the seat cushion 12, the seat cushion 12 will return to its original position due to its own gravity. In order to prevent the seat cushion 12 from returning to its original position and affecting the use, the user needs to hold the seat cushion 12 with his hands after the seat cushion 12 is lifted up, which is very inconvenient. For this reason, in this embodiment, the flipping mechanism 14 is further provided with an elastic member 144, which is used to limit the seat cushion 12 from returning to its original position after it is lifted up, so as to facilitate the user's use.

[0039] Furthermore, as mentioned above, the novel vehicle seat is provided with at least one set of tilting mechanisms 14. When only one set of tilting mechanisms 14 is provided, this set includes the aforementioned elastic member 144. When multiple sets of tilting mechanisms 14 are provided, at least one of these sets includes the aforementioned elastic member 144. The ends of the elastic member 144 are connected to the seat bucket 11 and the seat cushion 12, respectively. When the seat cushion 12 is lifted, the elastic member 144 restricts the rotation of the first link 141 and the second link 142, thereby preventing the seat cushion 12 from returning to its original position.

[0040] The new vehicle seat provided by the embodiment of the present utility model is as follows Figures 1 to 4 As shown, the two ends of the elastic member 144 are rotatably connected to the seat bucket 11 and the seat cushion 12 respectively; the connection point between the elastic member 144 and the seat bucket 11 is located below the connection point between the second connecting rod 142 and the seat bucket 11, and the connection point between the elastic member 144 and the seat cushion 12 is located above the connection point between the first connecting rod 141 and the seat cushion 12.

[0041] In this embodiment, one end of the elastic member 144 is rotatably connected to the seat bucket 11, and the connection point between the elastic member 144 and the seat bucket 11 is located below the connection point between the second connecting rod 142 and the seat bucket 11. The other end of the elastic member 144 is rotatably connected to the seat cushion 12, and the connection point between the elastic member 144 and the seat cushion 12 is located above the connection point between the first connecting rod 141 and the seat bucket 11. When the seat cushion 12 is lifted, the elastic member 144 will not cause the seat cushion 12 to return to its original position. Only when the elastic member 144 is used to push the seat cushion 12 back to its original position can the seat cushion 12 overcome the resistance and return to its original position.

[0042] Optionally, in this embodiment, the above-mentioned elastic member 144 can also have one end coincide with the connection point between the second connecting rod 142 and the seat bucket 11, and the other end coincide with the connection point between the first connecting rod 141 and the seat cushion 12, or one end of the elastic member 144 can be connected to the seat bucket 11, and the other end can be connected to the first connecting rod 141. The above methods can achieve the purpose of avoiding resetting after the seat is lifted up in this embodiment.

[0043] Preferably, the new vehicle seat provided by the embodiment of the present invention is as follows: Figures 1 to 4 As shown, the elastic member 144 is a spring, which has a simple structure, a long service life, and can adapt to various usage environments and has strong applicability.

[0045] The new vehicle seat provided by the embodiment of the present utility model is as follows Figures 1 to 4 As shown, the flip mechanism 14 also includes a first mounting seat 145 and a second mounting seat 146; the first mounting seat 145 is arranged on the back of the seat cushion 12, and the second mounting seat 146 is arranged on the seat barrel 11, and the two ends of the first connecting rod 141 and the second connecting rod 142 are rotatably connected to the first mounting seat 145 and the second mounting seat 146 respectively.

[0046] The above-mentioned flipping mechanism 14 also includes a first mounting seat 145 and a second mounting seat 146; the first mounting seat 145 can be fixed to the back of the seat cushion 12 by means of bolt connection or welding, and the back of the seat cushion 12 is the side opposite to the seat cushion 12; the second mounting seat 146 can be fixed to the seat bucket 11 by means of bolt connection or welding; the first mounting seat 145 is a plate with an L-shaped cross-section, and the second mounting seat 146 is a plate-like structure; pin holes are provided on the first mounting seat 145 and the second mounting seat 146; one end of the first connecting rod 141 is rotatably connected to the first mounting seat 145 through a pin and a corresponding pin hole, and the other end is rotatably connected to the second mounting seat 146 through a pin and a corresponding pin hole; one end of the second connecting rod 142 is rotatably connected to the first mounting seat 145 through a pin and a corresponding pin hole, and the other end is rotatably connected to the second mounting seat 146 through a copper drum pin and a corresponding pin hole. By setting the first mounting seat 145 and the second mounting seat 146 to install the first connecting rod 141 and the second connecting rod 142, it is possible to avoid adjusting the original structure of the seat cushion 12 and the seat barrel 11 due to the setting of the first connecting rod 141 and the second connecting rod 142, and the above-mentioned flipping mechanism 14 can be modularized, which facilitates the installation and maintenance of the flipping mechanism 14.

[0047] The new vehicle seat provided by the embodiment of the present utility model is as follows Figures 1 to 4 As shown, two groups of flipping mechanisms 14 are provided, and the two groups of flipping mechanisms 14 are respectively located at the two ends of the new vehicle seat in the left and right directions.

[0048] Preferably, in this embodiment, two sets of the aforementioned flipping mechanisms 14 are provided, and the two sets of flipping mechanisms 14 are located at the left and right ends of the new vehicle seat, thereby making the seat cushion 12 more stable during flipping. Furthermore, both sets of flipping mechanisms 14 include the aforementioned elastic member 144, so that the two sets of flipping mechanisms 14 are subjected to the same force during use, thereby increasing their service life.

[0049] The new vehicle seat provided by the embodiment of the present utility model is as follows Figures 1 to 4As shown, the interior of the seat bucket 11 is hollow; the seat cushion 12 can open or close the seat bucket 11.
