[0038] As Figures 1 - 8 shown, a preferred flipping device 100 in an embodiment of the present utility model includes a mounting member 1, a rotating shaft 2, a connecting member 3 and a locking mechanism 4; the rotating shaft 2 is rotatably connected to the mounting member 1 and can rotate around a first axis; the connecting member 3 is fixedly connected to the rotating shaft 2 and is used for connecting the seat body 200; the locking mechanism 4 includes a locking member 41, a sliding member 42, a locking element 43 and an elastic member 44. The locking member 41 is fixedly connected to the mounting member 1 and is located between the mounting member 1 and the connecting member 3. The locking member 41 is provided with a locking hole 412. The sliding member 42 is arranged between the connecting member 3 and the locking member 41 and is provided with a first connection hole 421. The sliding member 42 is sleeved and fixed on the rotating shaft 2 through the first connection hole 421 and can rotate around the first axis following the rotating shaft 2. The locking element 43 is connected to the sliding member 42 and can rotate around the first axis following the sliding member 42. Two ends of the elastic member 44 are respectively connected to the connecting member 3 and the sliding member 42. The elastic member 44 is used for driving the sliding member 42 to slide along the rotating shaft 2 when the locking element 43 and the locking hole 412 are aligned, so as to embed the locking element 43 into the locking hole 412.

[0039] Based on this technical solution, by sleeving and fixing the sliding member 42 on the rotating shaft 2 and connecting the connecting member 3 to the sliding member 42, the locking member 43 can rotate around the first axis following the rotating shaft 2. When the rotating shaft 2 rotates to a preset position, the locking member 43 is aligned with the locking hole 412, and the elastic force of the elastic member 44 drives the sliding member 42 to slide along the rotating shaft 2 towards the direction close to the locking member 41, so as to embed the locking member 43 into the locking hole 412 and restrict the rotation of the rotating shaft 2, thereby realizing the locking of the seat body 200; since the sliding member 42 can slide along the rotating shaft 2, the sliding member 42 can be driven to slide along the rotating shaft 2 towards the direction away from the locking member 41, so as to disengage the locking member 43 from the locking hole 412 and enable the rotating shaft 2 to rotate around the first axis, realizing the unlocking of the seat body 200; therefore, the locking mechanism 4 of the flipping device 100 provided by the present utility model can realize the locking and unlocking of the seat body 200 through the locking member 41, the sliding member 42, the locking member 43 and the elastic member 44, with a simple structure, fewer components and simple assembly.

[0040] The mounting member 1 is used for fixedly connecting with the vehicle body.

[0041] The first axis is the central axis of the rotating shaft 2.

[0042] In some embodiments, the locking mechanism 4 is used to lock the seat body 200 in the upright state of the seat flipping, so as to expand the interior space of the vehicle.

[0043] In this embodiment, the locking member 43 is a locking pin.

[0044] In some other embodiments, the locking member 43 can also be any locking member 43 such as a locking rod, a locking bolt, a locking strip, a locking column, etc. that can be embedded into the locking hole, which is not limited herein.

[0045] In this embodiment, the elastic member 44 is a telescopic spring.

[0046] In some other embodiments, the elastic member 44 can also be any elastic member 44 such as a tension spring, a compression spring, etc. that can drive the sliding member 42 to slide along the rotating shaft 2, which is not limited herein.

[0047] In this embodiment, two locking holes 412 are formed on the locking member 41, and two locking members 43 are connected to the sliding member 42. When the rotating shaft 2 rotates to a preset position, the two locking members 43 are respectively embedded into the two locking holes 412.

[0048] Specifically, the two locking holes 412 are symmetrically arranged about the first axis.

[0049] Refer to Figures 1 - 4, the flipping device 100 further includes an unlocking member 5. The unlocking member 5 has opposite first end 51 and second end 52. The first end 51 is connected to the sliding member 42, and the second end 52 is located on the side of the sliding member 42 away from the locking member 41. In this way, the unlocking member 5 can be operated on the side of the sliding member 42 away from the locking member 41 to drive the sliding member 42 to slide along the rotating shaft 2 in a direction away from the locking member 41, so that the locking member 43 is disengaged from the locking hole 412 to unlock the seat body 200, which is convenient to operate.

[0050] In this embodiment, the unlocking member 5 is an unlocking cable.

[0051] In some embodiments, the second end 52 of the unlocking member 5 is used to be connected to the unlocking motor of the ground lock, that is, the locking mechanism 4 of the flipping device and the ground lock can share one unlocking motor, so that the seat can unlock the locking mechanism 4 synchronously when unlocking the ground lock, without the need to additionally add a motor to unlock the locking mechanism, and the cost is low.

[0052] The connecting member 3 is provided with a guiding hole 31. The unlocking member 5 passes through the guiding hole 31, and the second end 52 is located on the side of the guiding hole 31 away from the sliding member 42. In this way, the guiding hole 31 can not only guide the movement process of the unlocking member 5 to pull the sliding member 42, but also the unlocking member 5 can be operated on the side of the guiding hole 31 away from the sliding member 42 to drive the sliding member 42 to slide along the rotating shaft 2 in a direction away from the locking member 41, so that the locking member 43 is disengaged from the locking hole 412 to unlock the seat body 200, which is convenient to operate.

[0053] Refer to Figures 1 - 3 and Figure 6 , the rotating shaft 2 has a first planar wall 21, and the first connecting hole 421 has a second planar wall 4211 that matches the first planar wall 21. Through the mutual cooperation of the first planar wall 21 and the second planar wall 4211, after the sliding member 42 is sleeved on the rotating shaft 2 through the first connecting hole 421, the functions of the sliding member 42 following the rotating shaft 2 to rotate around the first axis and the sliding member 42 sliding along the rotating shaft 2 can be realized. The structure is simple and the assembly is convenient and fast.

[0054] The outer wall of the rotating shaft 2 has a blocking wall 22. The blocking wall 22 is connected to one end of the first planar wall 21 close to the locking member 41 and is located between the sliding member 42 and the locking member 41. The use of the limiting wall can block the sliding of the sliding member 42 on the rotating shaft 2 to prevent the sliding member 42 from being too close to the locking member 41.

[0055] Refer to Figure 1 , Figure 3 and Figure 5, a circular ring-shaped guiding groove 411 is recessed on one side of the locking member 41 facing the sliding member 42 in a direction away from the sliding member 42. The center of the circular ring-shaped guiding groove 411 is located on the first axis, and the locking hole 412 is communicated with the circular ring-shaped guiding groove 411. In this way, during the process of the locking member 43 following the rotating shaft 2 to rotate around the first axis, one end of the locking member 43 close to the locking member 41 can be limited within the circular ring-shaped guiding groove 411, so that the circular ring-shaped guiding groove 411 can play a guiding and limiting role on the locking member 43. Furthermore, when the rotating shaft 2 rotates to a preset position, the locking member 43 can be better aligned with the locking hole 412, and can be more smoothly inserted into the locking hole 412 under the elastic force of the elastic member 44, improving the reliability.

[0056] The sliding disk is provided with a second connection hole 422, the locking member 43 is inserted through the second connection hole 422, and the elastic member 44 is sleeved on the locking member 43 and is located between the connecting member 3 and the sliding member 42. In this way, the locking member 43 can play a guiding and limiting role in the compression and extension process of the elastic member 44, so that the elastic force of the elastic member 44 can better push the sliding member 42 to move.

[0057] In this embodiment, the number of the elastic members 44 is two, and the two elastic members 44 are respectively sleeved on the two locking members 43.

[0058] Refer to Figures 1 - 3 and Figures 7 - 8 , the mounting member 1 includes a first mounting portion 11, a second mounting portion 12, a connecting portion 13, a first supporting portion 14 and a second supporting portion 15. The two ends of the connecting portion 13 are respectively connected to the first mounting portion 11 and the second mounting portion 12. The first mounting portion 11 and the second mounting portion 12 are both provided with through holes 16 for the rotating shaft 2 to pass through. The first mounting portion 11 and the second mounting portion 12 are both connected with a first supporting portion 14, and the first supporting portion 14 is located on the first side of the rotating shaft 2. The first mounting portion 11 and the second mounting portion 12 are both connected with a second supporting portion 15, and the second supporting portion 15 is located on the second side of the rotating shaft 2.

[0059] The flipping device further includes a flipping assisting mechanism 6, and the flipping assisting mechanism 6 is respectively connected to the mounting member 1 and the rotating shaft 2. The adoption of the flipping assisting mechanism 6 can not only offset part of the gravity of the seat body 200 when the seat changes from the sitting state to the storage state, so that the seat body 200 can be more smoothly stored in the pit, but also offset part of the gravity of the seat body 200 when the seat changes from the storage state to the sitting state, so as to reduce the external force required to flip the seat body 200. Therefore, the flipping mechanism provided by the present utility model can play an assisting role during the flipping process of the seat through the flipping assisting mechanism 6.

[0060] The flipping assist mechanism 6 includes a limiting member 61 and a first spring 62. The limiting member 61 is connected to the rotating shaft 2 and can rotate following the rotation of the rotating shaft 2. The limiting member 61 has a first limiting wall 611 and a second limiting wall 612. The first limiting wall 611 is located on the first side of the rotating shaft 2, and the second limiting wall 612 is located on the second side of the rotating shaft 2. The first spring 62 is sleeved on the rotating shaft 2, and the first spring 62 has a first acting arm 621 and a second acting arm 622. Wherein, the limiting member 61 has a first position and a second position. When the limiting member 61 is in the first position, the first acting arm 621 abuts against the first supporting portion 14, and the second acting arm 622 abuts against the second limiting wall 612. When the limiting member 61 is in the second position, the first acting arm 621 abuts against the first limiting wall 611, and the second acting arm 622 abuts against the second supporting portion 15. By using the limiting member 61 and the first spring 62, since the rotation of the rotating shaft 2 will drive the rotation of the limiting member 61, the abutting positions of the first acting arm 621 and the second acting arm 622 can be changed through the rotation of the limiting member 61, so as to store and release the elastic potential energy of the first spring 62, and further achieve the purpose of providing assistance during the flipping process of the seat by the flipping assist mechanism 6.

[0061] In this embodiment, the first spring 62 is a torsion spring.

[0062] In some other embodiments, the first spring 62 can also be a tension spring, a compression spring or any other spring that can store and release elastic potential energy to provide assistance during the flipping process of the seat, which is not limited herein.

[0063] In some embodiments, the limiting member 61 is provided with a square hole for the rotating shaft 2 to pass through and adapted to the square limiting portion of the rotating shaft 2. The limiting member 61 is sleeved on the rotating shaft 2 through the square hole and rotates following the rotation of the rotating shaft 2.

[0064] The flipping assist mechanism 6 further includes a second spring 63. The second spring 63 is sleeved on the rotating shaft 2, and the second spring 63 has a third acting arm 631 and a fourth acting arm 632. Wherein, when the limiting member 61 is in the first position, the third acting arm 631 abuts against the first supporting portion 14, and the fourth acting arm 632 abuts against the second limiting wall 612. When the limiting member 61 is in the second position, the third acting arm 631 abuts against the first limiting wall 611, and the fourth acting arm 632 abuts against the second supporting portion 15. By the rotation of the limiting member 61, the abutting positions of the third acting arm 631 and the fourth acting arm 632 are changed, so as to store and release the elastic potential energy of the second spring, so that the flipping assist assembly can provide greater assistance during the flipping process of the seat.

[0065] In this embodiment, the second spring 63 is a torsion spring.

[0066] In some other embodiments, the second spring 63 can also be a tension spring, a compression spring, or any other spring that can store and release elastic potential energy to assist in the flipping process of the seat, and is not limited herein.

[0067] In this embodiment, the elastic coefficients of the first spring 62 and the second spring 63 are different.

[0068] In some other embodiments, the elastic coefficients of the first spring 62 and the second spring 63 can also be the same.

[0069] Refer to Figure 9 , the embodiment of the present utility model further provides a seat, which includes the flipping device 100 of any one of the above, and further includes a seat body 200, and the connecting member 3 is connected to the seat body 200.

[0070] The above are only the preferred embodiments of the present utility model.
