[0052] Based on this technical solution, by arranging the first toggle member 142 above the first acting arm 131 and enabling the first toggle member 142 to abut against the first acting arm 131 when rotating from the preset position to the storage position, when the mounting member 141 drives the seat body 2 to flip downward around the first axis, the elastic member 13 can provide resistance to the rotation of the mounting member 141 through the mutual abutment between the first acting arm 131 and the first toggle member 142, thereby providing resistance to the falling of the seat body 2 and slowing down the falling speed of the seat body 2. Therefore, the flipping device provided by the utility model can achieve the purpose of slowing down the falling speed of the seat body 2 through the elastic member 13 and the first toggle member 142, and has a relatively simple structure, low assembly difficulty, and low production cost.

[0053] When the mounting member 141 rotates from the storage position to the preset position around the first axis, the elastic force of the elastic member 13 will be released and offset part of the gravity of the seat body. The elastic member 13 can provide assistance for the seat body to rise through the mutual abutment between the first action arm 131 and the first toggle member 142. Therefore, the elastic member 13 and the first toggle member 142 can also provide assistance for the seat body to rise.

[0054] It should be pointed out that the first axis of the rotating shaft 12 is the central axis of the rotating shaft 12 .

[0055] Optionally, the mounting member 141 is rotatably connected to the fixing member 11 through the rotating shaft 12. The specific connection mode can be that the rotating shaft 12 is rotatably connected to the fixing member 11 and can rotate around the first axis of the rotating shaft 12, and the mounting member 141 is fixedly connected to the rotating shaft 12 and can rotate around the first axis with the rotating shaft 12; or the rotating shaft 12 is fixedly connected to the fixing member 11, and the mounting member 141 is rotatably connected to the rotating shaft 12 and can rotate around the first axis of the rotating shaft 12.

The first limit piece 151 and the second limit piece 152 can respectively limit the positions of the first action arm 131 and the second action arm 132 to ensure that the first action arm 131 is on the motion trajectory of the first toggle member 142, thereby ensuring that the elastic member 13 can play a resistance role on the first action arm 131 at the preset position.

[0060] In this embodiment, the first limiting member 151 is a rod-shaped structure.

[0061] In some other implementations, the first limiting member 151 may also be in any shape, such as a plate-shaped structure, a prism-shaped structure, etc., which is not limited here.

[0062] In this embodiment, the second limiting member 152 is a rod-shaped structure.

[0063] In some other embodiments, the second limiting member 152 may also be in any shape, such as a plate-shaped structure, a prism-shaped structure, etc., which is not limited here.

The second toggle member 143 can further limit the position of the second action arm 132, which helps to position the fixing member 11, the elastic member 13 and the mounting assembly 14 relative to each other, and facilitates assembly.

[0065] In this embodiment, the mounting member also has an unfolded position; when the mounting member 141 rotates from the preset position to the unfolded position around the first axis, the second toggle member 143 can abut against the second action arm 132. When the mounting member 141 rotates from the preset position to the unfolded position around the first axis, the elastic member 13 can provide resistance to the rotation of the mounting member 141 through the mutual abutment between the second action arm 132 and the second toggle member 143, thereby providing resistance to the falling of the seat body 2 and slowing down the falling speed of the seat body 2; when the mounting member 141 rotates from the unfolded position to the preset position around the first axis, the elastic force of the elastic member 13 will release and offset part of the gravity of the seat body, and the elastic member 13 can provide assistance for the rising of the seat body through the mutual abutment between the second action arm 132 and the second toggle member 143, so that the elastic member 13 and the second toggle member 143 can provide resistance to the falling of the seat body and provide assistance for the rising of the seat body.

[0066] In this embodiment, the second shifting member 143 is a rod-shaped structure.

At this time, the first action arm 131 and the first limiting member 151 are in contact with each other, and the second action arm 132 and the second limiting member 152 are in contact with each other.

[0071] The mounting member 141 also has a first design position, which is located on a motion trajectory of the mounting member 141 rotating downward from a preset position to a storage position. When the mounting member 141 rotates around the first axis to the first design position, the first actuator 142 contacts the first action arm 131, and the first action arm 131 provides resistance to the rotation of the first actuator 142.

[0072] Preferably, the first design position coincides with the preset position, that is, when the mounting member 141 is located at the preset position, the first action arm 131 abuts against both the first limiting member 151 and the first shifting member 142. In this way, the elastic member 13 can act as a resistance during the entire falling process of the seat body 2 rotating from the preset position to the storage position, thereby slowing down the falling speed of the seat.

[0073] See also Figure 6-Figure 7 When the flip device is in the unfolded state, the mounting member 141 is in the unfolded position, and the seat is in the unfolded state. At this time, the second toggle member 143 abuts against the second action arm 132, and the first toggle member 142 does not contact the first action arm 131.

[0074] The mounting member 141 also has a second design position, which is located on the movement trajectory of the mounting member 141 rotating downward from the preset position to the unfolded position. When the mounting member 141 rotates around the first axis to the second design position, the second actuator 143 contacts the second actuating arm 132, and the second actuating arm 132 provides resistance to the rotation of the second actuator 143.

[0075] Preferably, the second design position coincides with the preset position, that is, when the mounting member 141 is located at the preset position, the two action arms 132 abut against both the second limiting member 152 and the second shifting member 143. In this way, the elastic member 13 can act as a resistance during the entire falling process of the seat body 2 rotating from the preset position to the unfolded position, thereby slowing down the falling speed of the seat body.

[0076] The flipping device has a first horizontal direction X, a second horizontal direction Y and a vertical direction. The first horizontal direction X and the second horizontal direction Y intersect and form a horizontal plane. The vertical direction Z is perpendicular to the horizontal plane.

The bottom plate 111, the first side plate 112, the second side plate 113, the first extension plate 114 and the second extension plate 115 are used, and can be connected to the vehicle body through the bottom plate 111 to complete the installation between the flip mechanism and the vehicle body. The first extension plate 114 and the second extension plate 115 can form an installation groove 116 with upper and lower openings. By installing the elastic member 13 in the installation groove 116, the bottom plate 111 can be prevented from interfering with the movement of the first actuating arm 131, so that when the installation component 14 rotates around the first axis to the first preset position and continues to rotate downward, the first toggle member 142 can toggle the first actuating arm 131 to move.

[0089] Specifically, the housing of the flip motor 16 is fixedly connected to the mounting member 141. When the flip motor 16 is working, the core shaft of the flip motor 16 remains stationary, and the housing of the flip motor 16 rotates and drives the mounting member 141 to rotate around the first axis.

[0090] Optionally, the flip motor 16 is an outer rotor motor or a brushless DC motor, or any other motor that can achieve the function of keeping the core shaft stationary and rotating the shell, which is not limited here.

[0091] See also Figure 14-16 The utility model also provides a seat, which includes any one of the above-mentioned flipping devices 1 and a seat body 2 connected to the mounting member 141.

[0092] The seat further includes a slide rail assembly 3, which includes an upper rail 31 and a lower rail 32. The upper rail 31 is fixedly connected to the lower end of the fixing member 11, and the lower rail 32 is used to be fixedly mounted on the vehicle body. The upper rail 31 and the lower rail 32 are matched with each other and can move along the lower rail 32. By using the upper rail 31 and the lower rail 32, the flip device 1 and the seat body 2 can be moved to a predetermined position along the lower rail 32 through the upper rail 31, and then the seat body 2 can be stored at the predetermined position, which helps to further expand the space inside the vehicle.

[0093] Specifically, the fixing member 11 is fixedly connected to the upper rail 31 through the bottom plate 111 .

[0094] The seat also includes a locking device 4, which includes a first locking mechanism 41 and a second locking mechanism 42. The first locking mechanism 41 is installed on the upper track 31, and the upper end of the second locking mechanism 42 is fixedly connected to the seat body 2, and the lower end can be locked on the first locking mechanism 41 or unlocked from the first locking mechanism 41. When the seat body 2 is required to be in the unfolded state, the first locking mechanism 41 and the second locking mechanism 42 can be locked with each other, so that the locking device 4 can support the seat body 2 and improve the strength of the seat body 2. When the seat body 2 is required to be transformed from the unfolded state to the stowed state, the seat body 2 can be moved to a predetermined position by the slide rail assembly 3, and then the first locking mechanism 41 and the second locking mechanism 42 are unlocked, and then the flipping device 1 is used to realize the flipping and stowing of the seat body 2.

[0095] The first locking mechanism 41 and the second locking mechanism 42 are locking mechanisms of the prior art, and are not described in detail herein.

[0096] Fig.14 and Fig.15 The seat is shown in the extended position.

[0097] In this embodiment, the seat body 2 is connected to the mechanical flip device 101 and the electric flip device 102 on both sides of the first horizontal direction X. The electric flip device 102 can form a support on one side of the seat body 2, and the mechanical flip device 101 can form a support on the other side. Therefore, the seat can form two-side support for the seat body 2 through the mechanical flip device 101 and the electric flip device 102 to stably support the seat body 2. At the same time, the electric flip device 102 can drive the rotating shaft 12 to rotate around the first axis, thereby driving the mounting assembly 14 to drive the seat body 2 to rotate around the first axis, so as to realize the automatic storage of the seat body 2, which is convenient to use. Compared with the method of arranging the electric flip device 102 on both sides of the seat body, the method of arranging the electric flip device 102 on only one side of the seat body 2 to realize the automatic flipping of the seat body 2 can simplify the structure of the seat, so as to reduce the number of parts required for assembling the seat, thereby being conducive to reducing the overall volume of the seat and reducing the production cost.

[0098] In some other embodiments, the seat body 2 may be connected to two mechanical flipping devices 101 on both sides of the first horizontal direction X to achieve flipping of the seat body, or the seat body 2 may be connected to two electric flipping devices on both sides of the first horizontal direction X to achieve flipping of the seat body.

[0099] In this embodiment, the mechanical flipping device 101 and the electric flipping device 102 are respectively installed on two slide rail assemblies 3 .

[0100] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
