Moreover, the first feature being "above", "above", and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "below", and "under" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the horizontal height of the first feature is lower than that of the second feature.

[0041] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by those skilled in the technical field to which this application belongs; the terms used in the description of the application in this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "comprising" and "having" and any variations thereof in the description of the specification, claims and drawings of this application are intended to cover non-exclusive inclusion.

[0042] Reference to "embodiment" in this application means that a specific feature, structure or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments.

[0043] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "X-axis direction", "Y-axis direction", "Z-axis direction", etc. is described based on the central axis of the rotating shaft 2 (i.e., the first axis) and the height direction of the seat. Among them, the Y-axis direction is parallel to the axis of the rotating shaft 2, the X-axis direction is perpendicular to the Y-axis direction, and the Z-axis direction is perpendicular to the Y-axis direction and parallel to the height direction of the seat.

[0044] As Figures 1 - 11 shown, a preferred electric flipping device in an embodiment of the present utility model includes a mounting member 1, a rotating shaft 2, a connecting member 3, a flipping motor 4 and a transmission assembly 5.

[0045] The mounting member 1 includes a mounting seat 11; the rotating shaft 2 is rotatably connected to the mounting seat 11, and the rotating shaft 2 has a first axis; the connecting member 3 is fixedly connected to the rotating shaft 2 and is used for connecting the seat body; the flipping motor 4 has an output shaft 41; the transmission assembly 5 includes a first winding wheel 51, a second winding wheel 52 and a first cable 53. The first winding wheel 51 is sleeved and fixed on the output shaft 41, the second winding wheel 52 is sleeved and fixed on the rotating shaft 2, one end of the first cable 53 is fixedly connected to the first winding wheel 51, the first cable 53 is wound around the second winding wheel 52, and the first cable 53 is fixedly connected to the second winding wheel 52 away from the first winding wheel 51.

[0046] Based on this technical solution, the output shaft 41 is driven by the reversing motor 4 to rotate around the second axis. The output shaft 41 can drive the first winding wheel 51 to rotate around the second axis. When the first winding wheel 51 rotates, it can wind and tighten the first cable 53. When the first cable 53 is tightened, it can drive the second winding wheel 52 to rotate around the first axis. When the second winding wheel 52 rotates, it can both unwind and release the first cable 53 and drive the rotating shaft 2 to rotate around the first axis. When the rotating shaft 2 rotates, it can drive the connecting member 3 to rotate, thereby driving the seat body to rotate around the first axis, realizing the automatic flipping of the seat body, which is convenient to use.

[0047] The reversing motor 4 realizes the flipping of the seat body through the first winding wheel 51, the second winding wheel 52 and the first cable 53, so that the reversing motor 4 can be arranged in the space of the seat body in the X-axis direction. Therefore, the electric flipping device provided by the present invention can be applied to places where the space of the seat is limited in the Y-axis direction and the Z-axis direction.

[0048] The mounting member 1, the rotating shaft 2 and the connecting member 3 form a flipping mechanism.

[0049] The existing transmission methods of electric flipping devices all adopt fixed connection transmission methods (such as gear transmission, the reversing motor and the flipping mechanism are integrated, etc.). However, the electric flipping device provided by the present invention realizes the flipping of the seat body by adopting a flexible transmission method composed of the first winding wheel 51, the second winding wheel 52 and the first cable 53. The flexible transmission method has the following advantages: First, it enables the reversing motor 4 and the flipping mechanism to be arranged separately, reducing the volume of the flipping mechanism. Second, since the cable can be bent, after the flipping mechanism is fixed, the reversing motor 4 can be arranged at other vacant positions of the vehicle, and the selection range of the arrangement space is larger. Third, the transmission ratio of the first winding wheel 51 and the second winding wheel 52 can be changed, so that the flipping device can meet the flipping requirements of seats with different masses and has a wider adaptability.

[0050] The first axis is the central axis of the rotating shaft 2, and the second axis is the central axis of the output shaft 41.

[0051] Refer to Figure 1 , the mounting member 1 provided by the embodiment of the present invention further includes a fixing frame 12, and the fixing frame 12 is fixedly connected to the mounting seat 11 and is used for connecting with the vehicle body.

[0052] Refer to 1- Figure 5, the electric flipping device provided by the embodiment of the present utility model further includes a flipping assist component 7, and the flipping assist component 7 is respectively connected to the mounting seat 11 and the rotating shaft 2. The flipping assist component 7 can play a role in assisting during the process of flipping the seat, so as to reduce the output power required for the flipping motor 4 to drive the seat to flip, thereby enabling the use of a flipping motor 4 with a smaller output power and a smaller volume to achieve the automatic flipping of the seat.

[0053] The flipping assist component 7 includes a limiting member 71 and an elastic member 72; the limiting member 71 is fixedly connected to the rotating shaft 2, and the limiting member 71 has a first limiting wall 7121 and a second limiting wall 7122; the elastic member 72 is sleeved on the rotating shaft 2, and the elastic member 72 has a first acting arm 721 and a second acting arm 722; the mounting seat 11 has a first supporting wall 1141 and a second supporting wall 1151, the first limiting wall 7121 and the first supporting wall 1141 are located on the first side of the rotating shaft 2, and the second limiting wall 7122 and the second supporting wall 1151 are located on the second side of the rotating shaft 2; wherein, the limiting member 71 has: a first position, at this time the first acting arm 721 abuts against the first supporting wall 1141, and the second acting arm 722 abuts against the second limiting wall 7122; a second position, at this time the first acting arm 721 abuts against the first limiting wall 7121, and the second acting arm 722 abuts against the second supporting wall 1151.

[0054] In this embodiment, when the limiting member 71 is in the first position, the seat is in the stowed state; when the limiting member 71 is in the second position, the seat is in the sitting state.

[0055] In some other embodiments, it may also be that when the limiting member 71 is in the first position, the seat is in the sitting state; when the limiting member 71 is in the second position, the seat is in the stowed state; this is not limited herein.

[0056] In this embodiment, when the seat is in the stowed state, the limiting member 71 is in the first position, the first acting arm 721 abuts against the first supporting wall 1141, the second acting arm 722 abuts against the second limiting wall 7122, and the elastic member 72 stores elastic potential energy; when the flipping motor 4 drives the rotating shaft 2 and the connecting member 3 to rotate through the transmission component 5 to drive the seat body to flip upward around the first axis to unfold the seat body, the rotating shaft 2 drives the limiting member 71 to rotate and causes the elastic member 72 to release the elastic potential energy; the released elastic potential energy can offset part of the gravitational potential energy when the seat body flips upward, and further can reduce the output power of the flipping motor 4, so that a flipping motor 4 with a smaller output power and a smaller volume can be used to achieve the automatic flipping of the seat.

[0057] When the limiting member 71 is flipped to a preset position, the elastic member 72 returns to a preset state, which can be either the natural stretching state of the elastic member 72, i.e., the state where the elastic member 72 does not store elastic potential energy, or the minimum compression state of the elastic member 72, i.e., the state where the elastic member 72 stores the minimum elastic potential energy.

[0058] When the limiting member 71 crosses the preset position and needs to be flipped from the preset position to the second position, the first acting arm 721 separates from the first supporting wall 1141 and abuts against the first limiting wall 7121, the second acting arm 722 separates from the second limiting wall 7122 and abuts against the second supporting wall 1151. The elastic member 72 stores elastic potential energy to offset part of the gravitational potential energy when the seat body is flipped downward, slowing down the speed of the seat body when it descends to improve the maneuverability when the seat body is flipped, until the limiting member 71 is in the second position and the seat is in the sitting state.

[0059] The elastic member 72 can be any elastic member such as a torsion spring, a tension spring, a compression spring, etc. that can assist in the flipping process of the flipping mechanism through the storage and release of elastic potential energy, and is not limited herein.

Both the first mounting plate 111 and the second mounting plate 112 are connected with a second supporting plate 115. The second supporting plate 115 is located on the second side of the rotation shaft 2, and the second supporting wall 1151 is provided on the second supporting plate 115.

[0061] The limiting member 71 includes a connecting portion 711 and a limiting portion 712. The limiting portion 712 is fixedly connected to the connecting portion 711. The connecting portion 711 is provided with a through fixing hole 7111. The connecting portion 711 is sleeved and fixed on the rotation shaft 2 through the fixing hole 7111. Both the first limiting wall 7121 and the second limiting wall 7122 are provided on the limiting portion 712.

One end of the second wire rope 54 is fixedly connected to the second winding wheel 52, the second wire rope 54 is wound around the first winding wheel 51, and the end of the second wire rope 54 away from the second winding wheel 52 is fixedly connected to the first winding wheel 51. By using the cooperation of the first wire rope 53 and the second wire rope 54, the rotating shaft 2 can be driven to rotate forward to realize the forward rotation and flipping of the seat when the flipping motor 4 rotates forward, and the rotating shaft 2 can also be driven to rotate reversely to realize the reverse rotation and flipping of the seat when the flipping motor 4 rotates reversely, which is more convenient to use.

[0063] In this embodiment, the first wire rope 53 is also wound around the first winding wheel 51, and the second wire rope 54 is also wound around the second winding wheel 52.

The first wire rope 53 is gradually tightened and drives the second winding wheel 52 to rotate forward. The forward rotation of the second winding wheel 52 can unwind and release the first wire rope 53 and can drive the rotating shaft 2 to rotate forward to realize the forward rotation and flipping of the seat body; at the same time, the forward rotation of the first winding wheel 51 can unwind and release the second wire rope 54, and the second winding wheel 52 rotates forward to wind the second wire rope 54; when the output shaft 41 of the flipping motor 4 rotates reversely, the first winding wheel 51 rotates reversely and winds the second wire rope 54.
