That is, the ground lock device 3 and the locking mechanism 24 of the flipping device 2 can share one unlocking motor 41 for unlocking. The operation is simple, the number of unlocking motors 41 is small, and the cost is reduced.

[0056] The seat body 1 includes a seat frame 11. The first connecting member 23 is fixedly connected to the seat frame 11. The ground lock device 3 is connected to the seat frame 11.

[0057] The seat body 1 further includes a cushion (not shown). The cushion is connected to the seat frame 11 and is used for the user to sit on and lean on.

[0058] In this embodiment, the unlocking motor 41 is installed on the seat body 1.

[0059] In some other embodiments, the unlocking motor 41 can also be installed on other components such as the vehicle body and the first mounting member 21, which is not limited herein.

[0060] The first axis is the central axis of the first rotating shaft 22.

[0061] The first mounting member 21 includes a first mounting bracket 211 and a first mounting seat 212. The first mounting bracket 211 is used to connect to the vehicle body. The first mounting seat 212 is connected to the first mounting bracket 211.

[0062] In this embodiment, the lock catch 31 is located on the rear side of the vehicle of the seat body 1. That is, when the seat body 1 is in the upright state, the side where the lock catch 31 is located is close to the rear of the vehicle, and the side of the seat body 1 facing away from the lock catch 31 is close to the front of the vehicle.

[0063] In some other embodiments, the buckle 31 may also be located on the headstock side of the seat body 1.

[0064] The seat further includes a tilting motor 7. The tilting motor 7 is connected to the first rotating shaft 22 and can drive the first rotating shaft 22 to rotate about the first axis.

[0065] Refer to Figures 5-11, the locking mechanism 24 provided by the embodiment of the present utility model includes a locking member 241, a guiding member 242, a locking element 243 and a first elastic member 244. The locking member 241 is fixedly connected to the first mounting member 21 and is located between the first mounting member 21 and the first connecting member 23. The locking member 241 is provided with a locking groove 2411. The guiding member 242 is fixedly connected to the first rotating shaft 22. The locking element 243 includes a body portion 2431 and a locking portion 2432. The body portion 2431 is slidably connected to the guiding member 242. The locking portion 2432 is fixedly connected to one end of the body portion 2431. The first elastic member 244 is respectively connected to the guiding member 242 and the body portion 2431. The first elastic member 244 is used to drive the locking element 243 to slide along the guiding member 242 when the locking portion 2432 and the locking groove 2411 are aligned, so as to embed the locking portion 2432 into the locking groove 2411. One end of the first unlocking cable 42 far from the unlocking motor 41 is fixedly connected to the locking element 243. By fixedly connecting the guiding member 242 to the rotating shaft, the guiding member 242 can rotate around the first axis following the rotating shaft. When the first rotating shaft 22 rotates to a preset position, the locking portion 2432 of the locking element 243 is aligned with the locking groove 2411 of the locking member 241. The elastic force of the first elastic member 244 drives the locking element 243 to slide along the guiding member 242 in a direction close to the locking member 241, so as to embed the locking portion 2432 into the locking groove 2411 and restrict the rotation of the rotating shaft, thereby realizing the locking of the seat body 1, with high structural stability. By fixedly connecting the first unlocking cable 42 to the locking element 243, the unlocking motor 41 winds up the first unlocking cable 42. The first unlocking cable 42 is tightened and drives the locking member 241 to move along the guiding member 242 in a direction away from the locking member 241. The locking portion 2432 disengages from the locking groove 2411 to realize the unlocking of the seat body 1. The unlocking motor 41 unwinds the first unlocking cable 42. The first unlocking cable 42 is relaxed so that the elastic force of the first elastic member 244 can drive the locking element 243 to move along the guiding member 242 in a direction close to the locking member 241, so that the locking portion 2432 can be embedded into the locking groove 2411 when the first rotating shaft 22 rotates to the preset position, so as to realize the locking of the seat body 1. Therefore, the locking mechanism 24 of the flipping device 2 provided by the present utility model can realize the locking of the seat body 1 through the locking member 241, the guiding member 242, the locking element 243 and the elastic member, with simple structure, fewer components, low cost, high structural stability and simple assembly. The seat provided by the present utility model can realize the automatic unlocking of the locking mechanism 24 through the unlocking motor 41, with convenient and fast operation.

[0066] It should be understood that in the present utility model, the locked state of the locking mechanism 24 refers to the locking portion 2432 being inserted into the locking groove 2411, resulting in restricting the first rotating shaft 22 from rotating about the first axis; the unlocked state of the locking mechanism 24 refers to the locking portion 2432 not being inserted into the locking groove 2411, and the first rotating shaft 22 can rotate about the first axis.

[0067] In this embodiment, the first elastic member 244 is a telescopic spring.

[0068] In some other embodiments, the first elastic member 244 can also be a compression spring, a pressure spring, or any elastic member that can be used to insert the locking portion 2432 into the locking groove 2411 when the locking portion 2432 and the locking groove 2411 are aligned. Elastic members that achieve this function by other means should also be regarded as within the protection scope of the present utility model.

[0069] The locking member 241 is provided with a first through hole 2412 for the first rotating shaft 22 to pass through.

[0070] One end of the guiding member 242 facing the locking member 241 is recessed away from the locking member 241 to form a sliding groove 2421. The main body portion 2431 is slidably connected to the inner side wall of the sliding groove 2421. The first elastic member 244 is disposed in the sliding groove 2421 and is located on the side of the locking member 243 away from the locking member 241. The sliding groove 2421 can play a role in limiting and guiding the main body portion 2431 through the inner side wall of the sliding groove 2421, so that the sliding groove 2421 can provide a stable sliding track for the main body portion 2431, thereby enabling the main body portion 2431 to maintain stability during the sliding process and reducing shaking and jitter, so that the locking portion 2432 can be accurately inserted into the locking groove 2411 when the first rotating shaft 22 rotates to a preset position, improving reliability.

[0071] Specifically, in this embodiment, the two ends of the first elastic member 244 are respectively connected to the bottom wall of the sliding groove 2421 and one end of the main body portion 2431 close to the bottom wall of the sliding groove 2421.

[0072] The side wall of the guiding member 242 is provided with an observation hole 2422 communicating with the sliding groove 2421. It is possible to observe the assembly situation of the first elastic member 244 and the main body portion 2431 in the sliding groove 2421 through the observation hole 2422, and it is also possible to load the first elastic member 244 into the sliding groove 2421 or take it out from the sliding groove 2421 through the observation hole 2422, facilitating the assembly between the first elastic member 244, the guiding member 242, and the locking member 243.

[0073] In this embodiment, one end of the guiding member 242 away from the locking member 241 is provided with a wire passing hole 2423 communicating with the sliding groove 2421. The first unlocking wire 42 passes through the wire passing hole 2423 and penetrates into the sliding groove 2421 and is connected to the main body portion 2431.

[0074] The first unlocking cable 42 is threaded through the first elastic member 244. The first unlocking cable 42 can limit the first elastic member 244 to prevent the first elastic member 244 from disengaging from the chute 2421.

[0075] Refer to Figures 2-5 and Figures 12-15 As shown in, the ground lock device 3 provided by the embodiment of the present utility model includes a lock catch 31 and a ground lock mechanism 32. The lock catch 31 is used to connect to the vehicle body, and the ground lock mechanism 32 is connected to the seat body 1.

[0076] The lock catch 31 includes a fixing plate 311 and a lock rod 312. The fixing plate 311 is used to connect to the vehicle body. Both ends of the lock rod 312 are connected to the fixing plate 311, and a limiting hole 313 is formed between the lock rod 312 and the fixing plate 311.

[0077] The ground lock mechanism 32 includes a fixing member 321 and a lock hook member 322. The fixing member 321 is connected to the seat body 1.

When the lock hook member 322 is in the locked state, the lock hook member 322 closes the opening 32112, and a locking groove 3214 for limiting the movement of the lock rod 312 is formed between the lock hook member 322 and the inner groove 32111. When the lock hook member 322 is in the unlocked state, the lock hook member 322 opens the opening 32112, and the opening 32112 is used for the lock rod 312 to enter or leave the inner groove 32111. By movably connecting the lock hook member 322 to the fixing member 321, the unlocking motor 41 can wind up the second unlocking cable 43. The second unlocking cable 43 is tightened and drives the lock hook member 322 to move so that the lock hook member 322 opens the opening 32112, so that the lock rod 312 can enter or leave the inner groove 32111 through the opening 32112 to achieve unlocking.

[0078] It should be understood that in the present utility model, the locked state of the ground lock device 3 means that the lock buckle 31 and the ground lock mechanism 32 are locked to each other; specifically, a locking groove 3214 is formed between the lock hook member 322 and the inner groove 32111, the lock rod 312 is disposed through the locking groove 3214, and the second lock hook member 322 is disposed through the limiting hole 313; the unlocked state of the ground lock device 3 means that the lock buckle 31 and the ground lock mechanism 32 are not locked to each other. Specifically, it may be that a locking groove 3214 is formed between the lock hook member 322 and the inner groove 32111 but the lock rod 312 is not within the inner groove 32111, or it may be that the lock hook member 322 opens the opening 32112 and the lock rod 312 can enter or leave the inner groove 32111 through the opening 32112; the locked state of the lock hook member 322 means that the lock hook member 322 closes the opening 32112, and a locking groove 3214 for limiting the movement of the lock rod 312 is formed between the lock hook member 322 and the inner groove 32111; the unlocked state of the lock hook member 322 means that the lock hook member 322 opens the opening 32112, and the opening 32112 is for the lock rod 312 to enter or leave the inner groove 32111; in summary, the ground lock device 3 being in the locked state is a sufficient but unnecessary condition for the lock hook member 322 to be in the locked state, that is, when the ground lock device 3 is in the locked state, the lock hook member 322 is in the locked state, and when the lock hook member 322 is in the locked state, the ground lock device 3 may be in the unlocked state.

[0079] The ground lock mechanism 32 further includes a second elastic member 323.

[0080] The lock hook member 322 includes a first pawl 3221 and a second pawl 3222. The first pawl 3221 is rotatably connected to the fixing member 321 and can rotate about the second axis. One end of the second unlocking cable 43 away from the unlocking motor 41 is fixedly connected to the first pawl 3221; the second pawl 3222 is rotatably connected to the fixing member 321 and can rotate about the third axis. The third axis is parallel to the second axis. When the lock hook member 322 is in the locked state, a locking groove 3214 for limiting the movement of the lock rod 312 is formed between the second pawl 3222 and the inner groove 32111.

[0081] Two ends of the second elastic member 323 are respectively connected to the first pawl 3221 and the second pawl 3222. Thus, when the unlocking motor 41 winds up the second unlocking cable 43, the second unlocking cable 43 is tightened and drives the first pawl 3221 to rotate about the second axis. The first pawl 3221 pulls the second pawl 3222 to rotate about the third axis through the second elastic member 323 and opens the opening 32112 of the second pawl 3222, so that the lock rod 312 can enter or leave the inner groove 32111 through the opening 32112, realizing the unlocking of the ground lock device 3.

[0082] In this embodiment, the second elastic member 323 is a tension spring.

[0083] In some other embodiments, the second elastic member 323 may also be any elastic member such as a compression spring, a telescopic spring, a pressure spring, etc., which is not limited herein.

[0084] In this embodiment, the fixing member 321 is provided with a first connection hole 3212 and a second connection hole 3213. The first pawl 3221 is rotatably connected to the fixing member 321 through the first connection hole 3212. The second axis is the central axis of the first connection hole 3212. The second pawl 3222 is rotatably connected to the fixing member 321 through the second connection hole 3213. The third axis is the central axis of the second connection hole 3213.

[0085] Referring to Figures 1-5 and Figures 16-21 , the seat provided by the embodiment of the present invention further includes a flipping assistance device 5. The flipping device 2 is connected to one side of the seat body 1, and the flipping assistance device 5 is connected to the other side of the seat body 1;

[0086] The flipping assistance device 5 includes a second mounting member 51, a second rotating shaft 52, a second connecting member 53, and a flipping assistance mechanism 54. The second mounting member 51 is used for connecting to the vehicle body. The second rotating shaft 52 is rotatably connected to the second mounting member 51 and can rotate around the first axis. The second connecting member 53 is fixedly connected to the second rotating shaft 52 and is located on one side of the second mounting member 51. The seat body 1 and the second connecting member 53 are fixedly connected. The flipping assistance mechanism 54 is respectively connected to the second mounting member 51 and the second rotating shaft 52.

[0087] The flipping assistance mechanism 54 can offset part of the gravity of the seat body 1 when the seat changes from the sitting state to the storage state, so that the seat body 1 can be more smoothly stored in the pit, and can also offset part of the gravity of the seat body 1 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 1; the flipping mechanism provided by the present invention plays an assisting role in the flipping process of the seat through the flipping assistance mechanism 54.

[0088] The flipping assistance device 5 can offset part of the gravity of the seat body 1 during the conversion process between the sitting state and the storage state of the seat, thereby reducing the external force required to flip the seat body 1, and further reducing the output power of the flipping motor 7, so that a flipping motor 7 with a smaller output power and a smaller volume can be used to realize the automatic flipping of the seat.

[0089] In this embodiment, the central axis of the second rotating shaft 52 and the central axis of the first rotating shaft 22 are collinear. Therefore, the first axis is also the central axis of the second rotating shaft 52.

[0090] The second mounting member 51 includes a second mounting bracket 511 and a second mounting base 512. The second mounting bracket 511 is used to be connected to the vehicle body, and the second mounting base 512 is connected to the second mounting bracket 511. The second mounting base 512 includes a first mounting portion 5121, a second mounting portion 5122, a connecting portion 5123, a first supporting portion 5124 and a second supporting portion 5125. The two ends of the connecting portion 5123 are respectively connected to the first mounting portion 5121 and the second mounting portion 5122. The first mounting portion 5121 and the second mounting portion 5122 are both provided with second through holes 5126 for the second rotating shaft 52 to pass through. The first mounting portion 5121 and the second mounting portion 5122 are both connected with a first supporting portion 5124, and the first supporting portion 5124 is located on the first side of the second rotating shaft 52. The first mounting portion 5121 and the second mounting portion 5122 are both connected with a second supporting portion 5125, and the second supporting portion 5125 is located on the second side of the second rotating shaft 52.

[0091] The flipping assisting mechanism 54 includes a limiting member 541 and a first assisting spring 542. The limiting member 541 is connected to the second rotating shaft 52 and can rotate around the first axis following the second rotating shaft 52. The limiting member 541 has a first limiting wall 5411 and a second limiting wall 5412. The first limiting wall 5411 is located on the first side of the second rotating shaft 52, and the second limiting wall 5412 is located on the second side of the second rotating shaft 52. The first assisting spring 542 is sleeved on the second rotating shaft 52, and the first assisting spring 542 has a first acting arm 5421 and a second acting arm 5422. Wherein, the limiting member 541 has a first position and a second position. When the limiting member 541 is in the first position, the first acting arm 5421 abuts against the first supporting portion 5124, and the second acting arm 5422 abuts against the second limiting wall 5412. When the limiting member 541 is in the second position, the first acting arm 5421 abuts against the first limiting wall 5411, and the second acting arm 5422 abuts against the second supporting portion 5125. By adopting the limiting member 541 and the first assisting spring 542, since the rotation of the second one will drive the limiting member 541 to rotate, the abutting positions of the first acting arm 5421 and the second acting arm 5422 can be changed through the rotation of the limiting member 541, so that the elastic potential energy of the first assisting spring 542 can be stored and released, and further the purpose of playing an assisting role in the flipping process of the seat through the flipping assisting mechanism 54 can be achieved.

[0092] In this embodiment, the connecting portion 5123 is connected to the second mounting bracket 511.

[0093] The flipping assist mechanism 54 further includes a second assist spring 543. The second assist spring 543 is sleeved on the rotating shaft. The second assist spring 543 has a third acting arm 5431 and a fourth acting arm 5432. When the limiting member 541 is in the first position, the third acting arm 5431 abuts against the first supporting portion 5124, and the fourth acting arm 5432 abuts against the second limiting wall 5412. When the limiting member 541 is in the second position, the third acting arm 5431 abuts against the first limiting wall 5411, and the fourth acting arm 5432 abuts against the second supporting portion 5125. By rotating the limiting member 541, the abutting positions of the third acting arm 5431 and the fourth acting arm 5432 are changed, so as to store and release the elastic potential energy of the second spring, so that the flipping assist assembly can play a greater assisting role during the flipping process of the seat.

[0094] Refer to Figures 1-5 、 Figure 16 and Figure 21 Accordingly, the seat provided by the embodiment of the present invention further includes a folding device 6. The fixing member 321 is connected to the seat body 1 through the folding device 6.

[0095] The folding device 6 includes a fixed seat 61, a connecting seat 62, a connecting shaft 63, a winding wheel 64 and a linkage rope 65. The fixed seat 61 is fixedly connected to the seat body 1. The connecting seat 62 is rotatably connected to the fixed seat 61 through the connecting shaft 63 and can rotate around a fourth axis. The fourth axis intersects with the second axis. The winding wheel 64 is sleeved and fixed on the second rotating shaft 52. The linkage rope 65 has a first connection end and a second connection end. The first connection end is fixedly connected to the winding wheel 64, and the second connection end is fixedly connected to the connecting seat 62. In this way, during the process of the seat body 1 flipping from the sitting state to the storage state, the winding wheel 64 winds up the linkage rope 65. The linkage rope 65 pulls the connecting seat 62 to rotate around the fourth axis. The connecting seat 62 drives the fixing member 321 to flip towards the direction close to the seat body 1, so as to gradually store the fixing member 321 in the seat body 1. That is, the fixing member 321 can be changed from the unfolded state to the stored and hidden state through the folding device 6.

[0096] In some embodiments, a return torsion spring can also be arranged on the connecting seat 62. During the process of the seat body 1 flipping from the storage state to the sitting state, the winding wheel 64 will unwind the linkage rope 65. The elastic force of the return torsion spring can be used to drive the connecting seat 62 to rotate around the fourth axis during the process of the winding wheel 64 unwinding the linkage rope 65, so as to drive the connecting seat 62 to drive the fixing member 321 to flip away from the seat body 1, so as to gradually unfold the fixing member 321. That is, the fixing member 321 can be changed from the stored and hidden state to the unfolded state through the return torsion spring.

[0097] The fourth axis is the central axis of the connecting shaft 63.

[0098] The seat further includes a controller (not shown), and the unlocking motor 41 and the flipping motor 7 are both electrically connected to the controller.

[0099] When the first rotating shaft 22 rotates to a preset position, the seat body 1 flips to a preset vertical locking position, and there is a preset locking angle a between the seat body 1 and the horizontal plane at the preset vertical locking position, and the preset angle range is b 。

[0100] Preferably, 85°≤a≤95°, a - 5°≤b≤a + 5°.

[0101] The conversion of the seat body 1 from the sitting state to the upright locked state is as follows: The unlocking motor 41 winds up the second unlocking cable 43. The second unlocking cable 43 is tightened and drives the first pawl 3221 to rotate around the second axis. The first pawl 3221 pulls the second pawl 3222 to rotate around the third axis through the second elastic member 323 and causes the second pawl 3222 to open the opening 32112 of the locking groove 3211. When the unlocking motor 41 winds up the second unlocking cable 43, the unlocking motor 41 also winds up the first unlocking cable 42 synchronously. Since the locking portion 2432 of the locking member 243 is not embedded in the locking groove 2411 of the locking member 241, that is, the locking portion 2432 of the locking member 243 abuts against the surface of the locking member 241 facing the guiding member 242 under the action of the first elastic member 244, the locking mechanism 24 is already in the unlocked state. Although the unlocking motor 41 winding up the first unlocking cable 42 can cause the locking portion 2432 to move away from the locking member 241 and make the locking portion 2432 disengage from the locking member 241, this unlocking action of the locking portion 2432 does not act on the seat body 1. The flipping motor 7 drives the first rotating shaft 22 to rotate around the first axis. The first rotating shaft 22 drives the seat body 1 to flip from the sitting state to the upright state through the connecting member. During the process of the seat body 1 flipping from the sitting state to the upright state, the locking rod 312 gradually leaves the inner groove 32111 through the opening 32112. After the locking rod 312 completely disengages from the locking groove 3211, the unlocking motor 41 unwinds the first unlocking cable 42 and the second unlocking cable 43. The relaxation of the first unlocking cable 42 enables the elastic force of the first elastic member 244 to drive the locking member 243 to move along the guiding member 242 towards the locking member 241, and the locking portion 2432 of the locking member 243 abuts against the surface of the locking member 241. During the process of the seat body 1 flipping from the sitting state to the upright state, the second rotating shaft 52 rotates around the first axis and drives the reel 64 to rotate around the first axis. The rotation of the reel 64 winds up the linkage rope 65. The linkage rope 65 is tightened and drives the connecting seat 62 to rotate around the fourth axis. The connecting seat 62 drives the fixing member 321 to fold towards the seat body 1 for the storage of the fixing member 321. When the seat body 1 is in the upright state, the first rotating shaft 22 is in the preset position. The locking portion 2432 of the locking member 243 and the locking groove 2411 of the locking member 241 are aligned. The locking portion 2432 is embedded in the locking groove 2411 under the action of the elastic force of the first elastic member 244, and the seat body 1 is locked in the upright state by the locking mechanism 24, that is, the seat body is in the upright locked state. When the controller detects a stall (i.e., the current of the flipping motor 7 suddenly increases to the stall current), it proves that the seat body 1 is already in the upright locked state at this moment, and the flipping motor 7 stops the flipping action.

[0102] The conversion of the seat body 1 from the upright locked state to the storage state is as follows: The unlocking motor 41 winds up the first unlocking cable 42 and the second unlocking cable 43. The first unlocking cable 42 is tightened and drives the locking member 241 to move away from the locking member 241, and the locking portion 2432 disengages from the locking groove 2411, realizing the unlocking of the locking mechanism 24. When the unlocking motor 41 winds up the first unlocking cable 42, the unlocking motor 41 also winds up the second unlocking cable 43 synchronously. Since the locking rod 312 is not in the locking groove 3211, that is, the locking hook member 322 and the locking rod 312 are not locked to each other. Although the unlocking motor 41 winding up the second unlocking cable 43 can drive the first pawl 3221 to rotate around the second axis and make the second pawl 3222 open the opening 32112 of the locking groove 3211, the unlocking action of the second pawl 3222 has no effect on the locking rod 312. When the controller detects that the locking mechanism 24 is unlocked, that is, the seat body 1 has been released from the upright locked state, the flipping motor 7 drives the first rotating shaft 22 to rotate around the first axis, and the first rotating shaft 22 drives the seat body 1 to flip from the upright state to the storage state through the connecting member. During the process of the seat body 1 being converted from the upright state to the storage state, the second rotating shaft 52 drives the reel 64 to rotate, the reel 64 winds up the linkage rope 65, and the linkage rope 65 pulls the driving connecting seat 62 to drive the fixing member 321 to fold towards the seat body 1 for the storage of the fixing member 321. When the seat body 1 is in the storage state, the fixing member 321 also folds and is stored in the seat body 1, that is, the fixing member 321 is in a storage and hidden state.

[0103] The action process of the seat body 1 being converted from the storage state to the upright locked state is similar to the action process of the seat body 1 being converted from the sitting state to the upright locked state. The difference is that during the action process of the seat body 1 being converted from the storage state to the upright locked state, since the reel 64 unwinds the linkage rope 65, the elastic force of the return torsion spring can be used to drive the connecting seat 62 to rotate around the fourth axis and gradually unfold the fixing member 321.

[0104] If the user needs to flip the seat body 1 from the sitting state to the storage state at one time: the unlocking motor 41 winds up the first unlocking wire rope 42 and the second unlocking wire rope 43, and the second unlocking wire rope 43 drives the second pawl 3222 to open the opening 32112 of the locking groove 3211 through the first pawl 3221 and the second elastic member 323; the flipping motor 7 drives the first rotating shaft 22 to rotate around the first axis, and the first rotating shaft 22 drives the seat body 1 to flip through the connecting member; during the flipping process of the seat body 1, the locking rod 312 gradually leaves the inner groove 32111 through the opening 32112, and after the locking rod 312 completely disengages from the locking groove 3211, the unlocking motor 41 stops operating; when the flipping position of the seat body 1 is close to the preset vertical locking position, that is, when the flipping angle of the seat body 1 is close to the preset locking angle a, and the flipping angle of the flipping body is within the preset angle range b, the unlocking motor 41 winds up the first unlocking wire rope 42 and the second unlocking wire rope 43, so that the first unlocking wire rope 42 can drive the locking member 243 away from the locking stop 241 and overcome the elastic force of the first elastic member 244 on the locking member 243, to prevent the locking member 243 from embedding the locking portion 2432 into the locking groove 2411 under the action of the elastic force of the first elastic member 244; when the seat body 1 crosses the preset angle range, the unlocking motor 41 stops operating, and the flipping motor 7 flips the seat body 1 through the first rotating shaft 22 and the connecting member until the seat body 1 flips to the storage position to be in the storage state; during the process of the seat body 1 flipping from the sitting state to the storage state, the second rotating shaft 52 drives the reel 64 to rotate, the reel 64 winds up the linkage rope 65, and the linkage rope 65 pulls the driving connecting seat 62 to drive the fixing member 321 to fold towards the seat body 1 to gradually store the fixing member 321. When the seat body 1 is in the storage state, the fixing member 321 also folds and is stored in the seat body 1, that is, the fixing member 321 is in the storage and hidden state.

[0105] Preferably, 45° ≤ a ≤ 135°.

[0106] In this embodiment, the preset locking angle a of the seat body 1 = 90°, and the preset angle range 85° ≤ b ≤ 95°.

[0107] In some other embodiments, the preset locking angle a of the seat body 1 can also be any angle value such as 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, 86°, 87°, 88°, 89°, 91°, 92°, 93°, 94°, 95°, 96°, 97°, 98°, 99°, 100°, 105°, 110°, 115°, 120°, 125°, 130°, 135°, etc., which is not limited herein.

[0108] In this embodiment, the number of the ground lock devices 3 is two, and the number of the second unlocking cables 43 is two. The two ground lock devices 3 are respectively connected to the unlocking motor 41 through the two unlocking cables.

[0109] In this embodiment, the number of the fixed seats 61 is two, the number of the connecting seats 62 is two, and the number of the connecting shafts 63 is two. The two fixed seats 61 are both connected to the seat body 1. The two fixed seats 61, the two connecting seats 62, the two connecting shafts 63 and the two ground lock devices 3 correspond to each other one by one.

[0110] In this embodiment, the linkage rope 65 includes a first cable 651 and two second cables 652. The first cable 651 has a first connection end, and the second cable 652 has a second connection end. The two connecting seats 62 and the two second cables 652 correspond to each other one by one. Specifically, the second connection end is connected to the connecting seat 62, and one end of the second cable 652 away from the second connection end is connected to one end of the first cable 651 away from the first connection end.

[0111] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can still be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
