[0069] Firstly, see Figures 1-17 This utility model provides a flipping device 100.

[0070] Example 1

[0071] like Figures 1-7 As shown, the first embodiment of this utility model provides a flipping device 100, which includes a mounting part 1, a rotating shaft 2, a connecting part 3 and a first assist spring 41.

[0072] Mounting component 1 includes mounting base 11, which has a first through hole 1111; rotating shaft 2 has a first axis, which passes through the first through hole 1111 and can rotate around the first axis; connecting component 3 is fixedly connected to rotating shaft 2 and located on one side of mounting base 11; first assist spring 41 includes first spring body 411, first action arm 412 and second action arm 413, the first spring body 411 is sleeved on rotating shaft 2 and located between mounting base 11 and connecting component 3, the first action arm 412 is fixedly connected to one end of the first spring body 411 and connected to mounting base 11, and the second action arm 413 is fixedly connected to the end of the first spring body 411 away from the first action arm 412 and connected to connecting component 3.

[0073] Based on this technical solution, by sleeved the first assist spring 41 on the rotating shaft 2 and connected to the mounting base 11 and the connecting member 3 respectively; when the mounting member 1 is installed in a fixed position (such as a fixed position on the vehicle body) and the connecting member 3 is fixedly connected to the seat body 200, the seat body 200 flips downward, which will cause the connecting member 3 to flip downward, so that the connecting member 3 can compress the first spring body 411 through the second action arm 413, so as to convert part of the gravitational potential energy of the seat body 200 flipping downward into the elastic potential energy of the first assist spring 41, thereby slowing down the speed of the seat body 200 when it falls, thus playing a buffering role and helping to improve the maneuverability of the seat body 200 when it flips downward; when the seat body 200 flips upward, it will cause the connecting member 3 to flip upward, so that the first assist spring 41 can extend and release the spring potential energy when the connecting member 3 flips upward, thereby offsetting part of the gravity when the seat body 200 flips upward, thus reducing the external force required when the seat body 200 flips upward, thus playing an assisting role, which is labor-saving, convenient to use, and simple in structure.

[0074] The first axis is the central axis of the first rotating shaft 2.

[0075] See 1- Figure 3 The flipping device 100 also includes a bushing 51, which is disposed between the outer wall of the rotating shaft 2 and the wall of the first through hole 1111. The bushing 51 serves to reduce noise and lubricate between the rotating shaft 2 and the first through hole 1111.

[0076] The flipping device 100 also includes a locking nut 52, which is fixedly connected to the end of the rotating shaft 2 away from the connector 3 and located on the side of the mounting base 11 opposite to the connector 3.

[0077] The flipping device 100 also includes a drive motor 53; the drive motor 53 is connected to the rotating shaft 2 and is used to drive the rotating shaft 2 to rotate around the first axis. The automatic flipping of the seat body 200 can be achieved by the drive motor 53, which is convenient to use; since the first assist spring 41 can play an assist function in the flipping process of the seat body 200 to reduce the external force required for the flipping of the seat body 200, the automatic flipping of the seat body 200 can be achieved by using the drive motor 53 with smaller output power and smaller size.

[0078] See Figures 1-4 The mounting base 11 provided in Embodiment 1 includes a first side plate 111, a first bottom plate 112, a second side plate 113, and a first support portion 114. The first side plate 111 is connected to one end of the first bottom plate 112, and the second side plate 113 is connected to the end of the first bottom plate 112 away from the first side plate and is disposed opposite to the first side plate 111. The first side plate 111 and the second side plate 113 are both provided with a first through hole 1111. A first receiving groove 115 is formed between the first side plate 111, the first bottom plate 112, and the second side plate 113. The first support portion 114 is connected to the end of the first side plate 111 away from the first bottom plate 112 and / or the end of the second side plate 113 away from the first bottom plate 112.

[0079] In this second embodiment, a first support portion 114 is connected to both the first side plate 111 and the second side plate 113.

[0080] The locking nut 52 is located on the side of the first side plate 111 opposite to the second side plate 113.

[0081] The mounting base 11 has a first connecting hole 1131, and a first actuating arm 412 passes through the first connecting hole 1131 to connect the first actuating arm 412 to the mounting base 11. Specifically, in this embodiment, the first connecting hole 1131 is provided on the second side plate 113.

[0082] Mounting component 1 also includes mounting bracket 12, and mounting base 11 is fixedly connected to mounting bracket 12.

[0083] Mounting component 1 also includes mounting bracket 12, which includes a second base plate 121 and a second support portion 122. The first base plate 112 is fixedly connected to the second base plate 121, and the second support portion 122 is fixedly connected to one end of the second base plate 121 and located on one side of the mounting base 11.

[0084] See Figures 1-4 ,and Figure 6The rotating shaft 2 provided in Embodiment 1 of this utility model includes a first shaft body 21 and a second shaft body 22 connected in sequence. The first shaft body 21 passes through the first through hole 1111, and the second shaft body 22 is located on the side of the second side plate 113 away from the first side plate 111. The connecting piece 3 is fixedly connected to the second shaft body 22. The diameter of the second shaft body 22 is larger than the diameter of the first shaft body 21, and the end of the second shaft body 22 near the second side plate 113 abuts against the second bearing 542.

[0085] The rotating shaft 2 also includes a mounting part 23, which is fixedly connected to the outer wall of the first shaft body 21. The rotating shaft 2 is fixedly connected to the drive hole of the drive motor 53 through the mounting part 23.

[0086] See Figures 1-4 ,and Figure 7 The connector 3 provided in Embodiment 1 of this utility model has a first mounting hole 31 and a second connecting hole 32. The rotating shaft 2 is fixedly connected to the connector 3 through the first mounting hole 31. The second action arm 413 passes through the second connecting hole 32 to be connected to the connector 3 through the second action arm 413.

[0087] Example 2

[0088] like Figures 8-10 As shown, unlike the flipping device 100 provided in Embodiment 1, the flipping device 100 provided in Embodiment 2 does not have a bushing 51 between the outer wall of the rotating shaft 2 and the hole wall of the first through hole 1111, and a bearing 54 is provided between the outer wall of the rotating shaft 2 and the hole wall of the first through hole 1111.

[0089] Currently available flipping devices 100 lack effective control over the assembly gap between the rotating shaft 2 and the first through hole 1111 of the mounting base 11, causing the seat to wobble significantly during flipping. However, the flipping device 100 provided in this embodiment improves the coaxiality of the rotating shaft 2 and the mounting base 11 by placing the bearing 54 between the outer wall of the rotating shaft 2 and the wall of the first through hole 1111 of the mounting base 11. This reduces the assembly gap between the rotating shaft 2 and the through hole, thereby helping to reduce the wobbling of the seat during flipping, and the structure is simple.

[0090] In this second embodiment, the bearing component 54 includes two bearings, namely a first bearing 541 and a second bearing 542. The first bearing 541 is disposed between the wall of the first through hole 1111 of the first side plate 111 and the outer wall of the first shaft 21, and the second bearing 542 is disposed between the wall of the first through hole 1111 of the second side plate 113 and the outer wall of the first shaft 21.

[0091] In some other embodiments, the bearing component 54 may also include any number of bearings, such as one, three, four, or five, without limitation.

[0092] In this second embodiment, both the first bearing 541 and the second bearing 542 are tapered roller bearings. The advantages of tapered roller bearings include high load-carrying capacity, self-aligning capability, and wide applicability.

[0093] The mounting base 11 provided in Embodiment 2 includes a first side plate 111, a first base plate 112, and a second side plate 113. The first side plate 111 is connected to one end of the first base plate 112, and the second side plate 113 is connected to the other end of the first base plate 112 and is disposed opposite to the first side plate 111. Both the first side plate 111 and the second side plate 113 have a first through hole 1111. A first receiving groove 115 is formed between the first side plate 111, the first base plate 112, and the second side plate 113. A locking thread nut 63 is attached to the side of the first side plate 111 facing away from the second side plate 113. In this way, the end of the locking nut 52 near the first side plate 111 can contact the first bearing 541. Therefore, during assembly, tightening the locking nut 52 allows the locking nut 52 and the first side plate 111 to approach each other and press against the first bearing 541, thereby achieving self-alignment and reducing assembly clearance.

[0094] Mounting base 11 has a first connecting hole 1131, and a first actuating arm 412 passes through the first connecting hole 1131 so that the first actuating arm 412 is connected to the mounting base 11.

[0095] The structural shape of the mounting bracket 12 provided in Embodiment 2 is different from that of the mounting bracket 12 provided in Embodiment 1.

[0096] Example 3

[0097] See Figures 11-12 Unlike the flipping device 100 provided in Embodiment 1, the flipping device 100 provided in Embodiment 3 further includes a leg-retracting roller 6. The leg-retracting roller 6 is fixedly connected to the mounting base 11 and located between the mounting base 11 and the connector 3. The leg-retracting roller 6 has a second through hole 61 through which the rotating shaft 2 passes. The first spring body 411 is disposed between the outer wall of the rotating shaft 2 and the hole wall of the second through hole 61.

[0098] During the folding and storage of the seat body 200, the support legs 723 of the seat need to be pulled by the leg-folding cable 73 to achieve the folding and storage of the support legs 723. By setting the leg-folding coil wheel 6 on the folding device 100, the leg-folding cable 73 can be guided and fixed during the folding process of the seat body 200. Thus, during the folding and storage of the seat body 200, the leg-folding cable 73 can be wound and tightened around the leg-folding coil wheel 6 to pull the support legs 723 to fold and store. Similarly, during the folding and unfolding process of the seat body 200, the leg-folding cable 73 can be loosened by winding around the leg-folding coil wheel 6, so that the support legs 723 of the seat can be gradually unfolded.

[0099] Example 4

[0100] See Figures 13-17 Unlike the flipping device 100 provided in Embodiment 1, the flipping device 100 provided in Embodiment 4 further includes a flipping assist component 42, which includes a connecting shaft 421, a limiting member 422, a second assist spring 423, a first gear 424, and a second gear 425.

[0101] The connecting shaft 421 has a second axis. Both ends of the connecting shaft 421 pass through the first side plate 111 and the second side plate 113 respectively and are rotatable around the second axis. A limiting member 422 is fixedly connected to the connecting shaft 421 and located within the first receiving groove 115. The limiting member 422 has a first limiting wall 4221 and a second limiting wall 4222. The second assist spring 423 includes a second spring body 4231, a third actuating arm 4232, and a fourth actuating arm 4233. The second spring body 4231 is sleeved on the connecting shaft 421 and located within the first receiving groove 115. The third actuating arm 4232 is fixedly connected to one end of the second spring body 4231, and the fourth actuating arm 4233 is fixedly connected to the first actuating arm 115. The end of the second spring body 4231 away from the third action arm 4232 is fixedly connected to the connecting shaft 421 and located on the side of the second side plate 113 away from the limiting member 422. The second gear 425 is fixedly connected to the rotating shaft 2 and meshes with the first gear 424. The limiting member 422 has a first position and a second position. When the limiting member 422 is in the first position, the third action arm 4232 abuts against the first support part 114 and the fourth action arm 4233 abuts against the second limiting wall 4222. When the limiting member 422 is in the second position, the third action arm 4232 abuts against the first limiting wall 4221 and the fourth action arm 4233 abuts against the second support part 122.

[0102] The rotation of the limiting member 422 changes the contact position of the third action arm 4232 and the fourth action arm 4233, thereby storing and releasing the elastic potential energy of the second assist spring 423. This allows the flip assist assembly 42 to provide greater assistance during the seat flipping process. Specifically, the flip assist assembly 42 can convert more gravitational potential energy of the seat body 200 when flipping downwards into elastic potential energy, further improving the maneuverability of the seat body 200 when flipping downwards. It can also counteract more gravitational potential energy with more elastic potential energy when the seat body 200 flips upwards, further reducing the external force required for the seat body 200 to flip upwards. The flip assist assembly 42 is suitable for flipping heavy-duty seats.

[0103] The second axis is the central axis of connecting shaft 421.

[0104] Specifically, the second gear 425 is fixedly connected to the second shaft 22.

[0105] Secondly, see Figures 18-27 The present invention also provides a seat, which includes a flipping device 100 as described above, and a seat body 200, with a connector 3 fixedly connected to one end of the seat body 200.

[0106] Example 5

[0107] See Figures 18-24 The seat provided in Embodiment 5 includes the flipping device 100 provided in Embodiment 3, and also includes a ground lock device 300. The ground lock device 300 includes a buckle 71, a ground lock mechanism 72, a leg retraction cable 73, and an unlocking cable 74.

[0108] Understandable, Figure 18 The seat body 200 only shows the seat cushion frame.

[0109] The latch 71 includes a fixing plate 711 and a locking rod 712. The fixing plate 711 is used to connect to the vehicle body. Both ends of the locking rod 712 are connected to the fixing plate 711, and a limiting hole 713 is formed between the locking rod 712 and the fixing plate 711.

[0110] The floor lock mechanism 72 includes a mounting bracket 721, a mounting shaft 722, a support leg 723, a return torsion spring 724, a fixing member 725, and a locking hook member 726. The mounting bracket 721 is fixedly connected to the seat body 200. The mounting shaft 722 has a third axis. One end of the support leg 723 is rotatably connected to the mounting bracket 721 through the mounting shaft 722 so that the support leg 723 can rotate around the third axis. The return torsion spring 724 is sleeved on the mounting shaft 722 and is connected to the mounting bracket 721 and the support leg 723 respectively.

[0111] The fastener 725 is fixedly connected to the end of the support leg 723 away from the mounting shaft 722. The fastener 725 has a locking groove 7251, which includes an inner groove 72511 and an opening 72512 communicating with the inner groove 72511. The locking hook 726 is movably connected to the fastener 725.

[0112] The two ends of the leg retraction cable 73 are connected to the support leg 723 and the leg retraction retraction wheel 6, respectively.

[0113] One end of the unlocking cable 74 is fixedly connected to the locking hook 726, and the end of the unlocking cable 74 away from the locking hook 726 is used to connect to the unlocking device.

[0114] When the locking hook 726 is in the locked state, the locking hook 726 closes the opening 72512, and a locking groove 72621 is formed between the locking hook 726 and the inner groove 72511 to limit the movement of the locking rod 712; when the locking hook 726 is in the unlocked state, the locking hook 726 opens the opening 72512, and the opening 72512 is used to allow the locking rod 712 to enter or leave the inner groove 72511.

[0115] The third axis is the center axis of the mounting shaft 722.

[0116] During the folding and folding process of the seat body 200, the leg-folding cable 73 can be wound and tightened around the leg-folding reel 6, pulling the seat support leg 723 to overcome the elastic force of the return torsion spring 724 and rotate around the third axis, thereby folding and folding the support leg 723. Similarly, during the folding and unfolding process of the seat body 200, the elastic force of the return torsion spring 724 drives the support leg 723 to rotate around the third axis and unfold the support leg 723; during the unfolding process of the support leg 723, the support leg 723 pulls the leg-folding cable 73 to unwind from the leg-folding reel 6.

[0117] The unlocking device may include, but is not limited to, unlocking motors, manual unlocking devices, etc.

[0118] By movably connecting the locking hook 726 to the fixing member 725, the unlocking cable 74 can be wound up by the unlocking device. The unlocking cable 74 is tightened and drives the locking hook 726 to move, so that the locking hook 726 opens the opening 72512, thereby allowing the locking rod 712 to enter or leave the inner groove 72511 through the opening 72512, thus achieving unlocking.

[0119] It should be understood that, in this utility model, the locked state of the ground lock device 300 refers to the mutual locking of the latch 71 and the ground lock mechanism 72. Specifically, a locking groove 72621 is formed between the locking hook 726 and the inner groove 72511, the locking rod 712 passes through the locking groove 72621, and the second locking hook 726 passes through the limiting hole 713; the unlocked state of the ground lock device 300 refers to the mutual locking of the latch 71 and the ground lock mechanism 72. Specifically, it can be that a locking groove 72621 is formed between the locking hook 726 and the inner groove 72511 but the locking rod 712 is not in the inner groove 72511, or it can be that the locking hook 726 opens the opening 72512 and the locking rod 712 can enter or leave the inner groove 72511 through the opening 72512; the locked state of the locking hook 726 refers to the mutual locking of the latch 71 and the ground lock mechanism 72511. The locking hook 726 closes the opening 72512, and a locking groove 72621 is formed between the locking hook 726 and the inner groove 72511 to limit the movement of the locking rod 712; the unlocked state of the locking hook 726 means that the locking hook 726 opens the opening 72512, and the opening 72512 is used to allow the locking rod 712 to enter or leave the inner groove 72511; in summary, the ground lock device 300 being in the locked state is a sufficient but not necessary condition for the locking hook 726 to be in the locked state, that is, if the ground lock device 300 is in the locked state, the locking hook 726 is in the locked state, and the ground lock device 300 may be in the unlocked state while the locking hook is in the locked state.

[0120] The ground lock mechanism 72 also includes a reset spring 727; the lock hook 726 includes a first pawl 7261 and a second pawl 7262. The first pawl 7261 is rotatably connected to the fixing member 725 and can rotate around the fourth axis. One end of the unlocking cable 74 is fixedly connected to the first pawl 7261. The second pawl 7262 is rotatably connected to the fixing member 725 and can rotate around the fifth axis. The fifth axis and the fourth axis are parallel. When the lock hook 726 is in the locked state, a locking groove 72621 for limiting the movement of the lock rod 712 is formed between the second pawl 7262 and the inner groove 72511. One end of the unlocking cable 74 is fixedly connected to the first pawl 7261. The two ends of the reset spring 727 are respectively connected to the first pawl 7261 and the second pawl 7262. Thus, when the unlocking device rewinds the unlocking cable 74, the second unlocking cable 74 tightens and drives the first pawl 7261 to rotate around the fourth axis. The first pawl 7261, through the return spring 727, pulls the second pawl 7262 to rotate around the fifth axis, causing the second pawl 7262 to open the opening 72512. This allows the locking rod 712 to enter or leave the inner groove 72511 through the opening 72512, thereby unlocking the locking hook 726. When the unlocking device unwinds the unlocking cable 74, under the elastic force of the return spring 727, the first pawl 7261 rotates around the fourth axis, and the second pawl 7262 rotates around the fifth axis, causing the second pawl 7262 to close the opening 72512, thereby locking the locking hook 726.

[0121] Example 6

[0122] See Figures 25-26 The seat provided in Embodiment Six includes the flipping device 100 provided in Embodiment Three. The seat also includes a support device 400. The support device 400 includes a support frame 81, a support shaft 82, and a support seat. The support frame 81 is used to connect to the vehicle body. The support seat 83 is fixedly connected to the end of the seat body 200 away from the flipping device 100. The support shaft 82 has a sixth axis, which coincides with the first axis. One end of the support seat 83 is rotatably connected to the support frame 81 through the support shaft 82 so that the support seat 83 can rotate around the sixth axis.

[0123] The sixth axis is the central axis of the support shaft 82.

[0124] The seat body 200 can be flipped downwards and stored in the recess 500 through the coordinated operation of the support device 400 and the flipping device 100, or the seat body 200 can be flipped upwards and removed from the recess 500 and unfolded.

[0125] Example 7

[0126] See Figure 27 The seat provided in Embodiment 7 is a split seat, with two seat bodies 200. The two seat bodies 200 include a first seat body 201 and a second seat body 202, which are arranged side by side.

[0127] There are two flipping devices 100, including a first flipping device 101 and a second flipping device 102. The first flipping device 101 is connected to the end of the first seat body 201 away from the second seat body 202, and the second flipping device 102 is connected to the end of the second seat body 202 away from the first seat body 201.

[0128] There are two support devices 400, including a first support device 401 and a second support device 402. The first support device 401 is connected to the end of the first seat body 201 near the second seat body 202, and the second support device 402 is connected to the end of the second seat body 202 near the first seat body 201. The first support device 401 and the second support device 402 are arranged at intervals.

[0129] By setting the first support device 401 and the second support device 402 to connect the first seat body 201 and the seat body 200 respectively, the first seat body 201 or the second seat body 202 can be flipped independently, which is convenient to use. The support frame 81 is set in the recess 500, which can prevent the two seat bodies 200 from having a protrusion between them when they are stored and folded, thereby improving the flatness of the split seat when stored.

[0130] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
