Description

Technical Field

[0001] This utility model relates to the field of seat technology, and in particular to a flipping mechanism and a seat. Background Technology

[0002] Currently, in the design of car seats, considering users' sitting and reclining needs as well as the demand for large storage space in the vehicle, a flip mechanism is incorporated to allow the seat to be flipped up, facilitating its storage and concealment. Flip mechanisms are divided into manual and electric types. When storing split seats, especially the six-part side seats, a significant force is required for flipping. Currently, electric flip mechanisms for six-part side seats rely on high-torque motors for direct drive. These motors are relatively large, requiring substantial installation space, resulting in a less compact overall structure and occupying significant interior space. Utility Model Content

[0011] A flip-assisted component is connected to the other end of the rotating shaft;

[0012] When the motor drives the drive shaft to rotate, the drive shaft moves circumferentially along the gear, causing the connecting member to rotate around the first axis following the drive shaft.

The gears are coaxial and spaced apart on the outer periphery of the rotating shaft. The motor is connected to the transmission shaft for transmission, and the transmission shaft meshes with the gears.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0055] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0056] See Figure 1 and Figure 2As shown, this utility model embodiment provides a flipping mechanism 200, including a connector 10, a rotating shaft 20, a motor 30, a transmission shaft 40, a gear 50, and a flipping assist component. The connector 10 is used to connect to the seat body 100; the rotating shaft 20 has a first axis, one end of the rotating shaft 20 is connected to the connector 10, and the rotating shaft 20 and the connector 10 are fixedly connected so that the rotating shaft 20 and the connector 10 can rotate synchronously; the motor 30 is mounted on the connector 10; the transmission shaft 40 is mounted on the connector 10, and the transmission shaft 40 is connected to the motor 30 in a transmission connection; the gear 50 is coaxial and spaced on the outer periphery of the rotating shaft 20, and the gear 50 is meshed with the transmission shaft 40, and the end of the transmission shaft 40 connected to the gear 50 is provided with gear teeth; the flipping assist component is connected to the other end of the rotating shaft; when the motor 30 drives the transmission shaft 40 to rotate, the transmission shaft 40 moves along the circumference of the gear 50, so that the connector 10 follows the transmission shaft 40 to rotate around the first axis. The drive shaft 40 drives the connector 10 and the rotating shaft 20 to rotate around the first axis of the rotating shaft 20. At the same time, the flipping assist component provides assistance for the rotation of the rotating shaft 20, so as to realize the flipping of the seat body 100 connected to the connector 10.

[0057] One end of the rotating shaft 20 is connected to the connector 10, and the other end of the rotating shaft 20 is connected to the tilting assist component, which provides assistance for the rotation of the rotating shaft 20 and the seat body 100. On the one hand, the motor 30 is integrated on the connector 10. The motor 30 transmits power through meshing gears, driving the connector 10 to rotate, so that the rotating shaft 20 and the seat body 100 connected to the connector 10 rotate, achieving the effect of increasing torque and reducing speed, which is convenient for using a small motor. On the other hand, the tilting assist component is connected to the other end of the rotating shaft 20, which provides assistance for the rotation of the rotating shaft 20 and the seat body 100. The same tilting mechanism 200 is used to achieve dual assistance for the rotation of the seat body 100, reducing the output efficiency of the motor 30, which is convenient for using a small motor, reducing the installation space required by the motor 30, thereby reducing the space occupied by the motor 30 in the vehicle, and improving the structural compactness of the entire tilting mechanism 200, which also reduces the space occupied by the tilting mechanism 200 in the vehicle.

[0058] Furthermore, the motor 30 is fixed to the connector 10 and connected to the seat body 100 through the connector 10, which facilitates the disassembly and assembly of the motor 30 and makes it easy for the motor 30 to be adapted to different seat bodies 100.

[0059] See Figure 3 and Figure 4 As shown, in some embodiments, the connector 10 is provided with a receiving groove 101, and the motor 30 is installed in the receiving groove 101. The receiving groove 101 provides installation space for the motor 30, and the receiving groove 101 can also provide protection for the motor 30.

[0060] See Figures 1-4As shown, in some embodiments, the flipping mechanism 200 further includes a fixing member 13 and a fastener 14. The fixing member 13 is disposed on the connecting member 10 and has a threaded hole. The fastener 14 is connected to the motor 30, and the fastener 14 is threaded into the threaded hole. The cooperation between the fixing member 13 and the fastener 14 facilitates the assembly and disassembly of the motor 30. The fixing member 13 can be a nut, and the fastener 14 can be a bolt.

[0061] See Figures 1-4 As shown, in some embodiments, the connector 10 has a connecting surface 102 on one side, and the rotating shaft 20 is connected to the connecting surface 102; the connecting surface 102 has a first mounting hole 1021, and the drive shaft 40 is rotatably assembled in the first mounting hole 1021. The connecting surface 102 facilitates the connection of the rotating shaft 20 and the installation of the drive shaft 40. The connecting surface 102 can serve as one of the groove walls of the receiving groove 101.

[0062] See Figure 4 As shown, in some embodiments, the flipping mechanism 200 further includes a reinforcing plate 11, which is at least partially attached and fixed to the connecting surface 102. The reinforcing plate 11 enhances the overall strength of the connector 10. By attaching and fixing the reinforcing plate 11 to the connecting surface 102, the structural strength at the location of the connecting surface 102 is enhanced, improving the connection stability between the rotating shaft 20 and the drive shaft 40 and the connector 10, thereby improving the overall connection stability between the flipping mechanism 200 and the seat body 100. A first mounting hole 1021 is provided through the reinforcing plate 11. To improve the installation stability of the drive shaft 40, a sleeve 12 is provided at the first mounting hole 1021, and the sleeve 12 is fixed to the reinforcing plate 11. The sleeve 12 not only facilitates the positioning and installation of the drive shaft 40 but also improves the support stability of the drive shaft 40.

[0063] In some embodiments, the rotating shaft 20 is a stepped shaft. The first axis is the central axis of the rotating shaft 20. See also Figure 3 and Figure 4 As shown, the connector 10 is also provided with a fixing hole 1022, which can be formed on the connecting surface 102. The end of the rotating shaft 20 connected to the connector 10 is referred to as the fixing end. The fixing end is located inside the fixing hole 1022, and the radial cross-sectional shape of the fixing end is adapted to the cross-sectional shape of the fixing hole 1022. The cross-sectional shape of the fixing hole 1022 can be triangular, semi-circular, or other shapes, so that the rotating shaft 20 and the connector 10 rotate synchronously and avoid relative rotation between them.

[0064] See Figure 1 and Figure 2As shown, in some embodiments, the flipping mechanism 200 further includes a mounting base 60 and a mounting bracket 61. The mounting base 60 is used to connect to the vehicle body, and the mounting bracket 61 is connected to the mounting base 60. The rotating shaft 20 is rotatably mounted on the mounting bracket 61, and the flipping assist component is mounted on the mounting bracket 61. The mounting base 60 and the mounting bracket 61 connect the rotating shaft 20 to the vehicle body, thereby connecting the flipping mechanism 200 to the vehicle body. A positioning pin 601 is provided on the mounting base 60, which is used to cooperate with the positioning hole on the vehicle body to facilitate the positioning and installation of the mounting base 60 on the vehicle body.

[0065] See Figure 1 , Figure 2 and Figure 5 As shown, in some embodiments, the flipping mechanism 200 further includes a fixed bracket 70, which is connected to the mounting base 60, and the gear 50 is mounted on the fixed bracket 70. The fixed bracket 70 provides a mounting carrier for the gear 50, allowing the gear 50 to be connected and fixed to the mounting base 60. The fixed bracket 70 has a through hole 701, and the fixed bracket 70 is coaxially and spaced around the outer periphery of the rotating shaft 20 through the through hole 701. The gear 50 is coaxially fixed to the end of the fixed bracket 70 away from the mounting base 60. One end of the fixed bracket 70 is connected to the mounting base 60, and the other end of the fixed bracket 70 is spaced apart from the connecting member 10. The diameter of the through hole 701 on the fixed bracket 70 is larger than the shaft diameter of the rotating shaft 20. Optionally, the fixed bracket 70 is in the shape of a sleeve 12. The gear 50 is fixedly connected to the fixed bracket 70, and the two can be welded together.

[0066] In some embodiments, the flip-up assist component connects the pivot 20 and the mounting bracket 61. The flip-up assist component assists the motor 30 in flipping the seat, reducing the force required to flip the seat, thereby reducing the output power required by the motor 30 to flip the seat. This allows for the use of a smaller motor 30 to achieve seat flipping, further reducing the size of the motor 30, minimizing its space occupation, facilitating its installation and fixation on the connector 10, and improving the overall compactness of the flipping mechanism 200. Furthermore, integrating the motor 30 and the flip-up assist component onto the same flipping mechanism 200 not only improves the structural compactness of the flipping mechanism 200 but also makes it easier to flip and store the six-part side seats in a split-type seat, requiring less effort.

[0067] See Figure 1 , Figure 2 , Figures 6-10As shown, in some embodiments, the flipping assist component includes a trigger 80 and an elastic member 90. The trigger 80 is connected to the rotating shaft 20 and has a first trigger part 801 and a second trigger part 802. The elastic member 90 is sleeved on the rotating shaft 20 and has a first action arm 901 and a second action arm 902. The mounting bracket 61 is provided with a first limiting member 611 and a second limiting member 612, which are located on both sides of the rotating shaft 20, respectively.

[0068] The trigger 80 has a first state and a second state. In the first state, the first trigger part 801 abuts against the first actuating arm 901, and the second actuating arm 902 abuts against the second limiting member 612. In the second state, the second trigger part 802 abuts against the second actuating arm 902, and the first actuating arm 901 abuts against the first limiting member 611.

[0069] In the first state, the seat is in a retracted position. At this time, the elastic element 90 accumulates elastic potential energy. When the motor 30 drives the drive shaft 40 to rotate, the drive shaft 40 moves circumferentially along the gear 50. The drive shaft 40 drives the connecting member 10 and the rotating shaft 20 to rotate around the first axis of the rotating shaft 20. Through the connecting member 10, the seat body 100 is gradually flipped and unfolded. When the rotating shaft 20 rotates, the trigger 80 rotates with the rotating shaft 20, causing the first trigger part 801 of the trigger 80 to move away from the first actuating arm 901. The elastic element 90 releases its elastic potential energy, assisting the movement of the first trigger part 801, thereby assisting the rotation of the rotating shaft 20. This assistance can offset part of the gravitational potential energy when the seat body 100 flips upward, making it easier for the seat body 100 to flip upward and reducing the output efficiency of the motor 30.

[0070] As the trigger 80 and the rotating shaft 20 continue to rotate, the elastic potential energy stored in the elastic element 90 is gradually released, and the elastic element 90 returns to its initial state. In this initial state, the elastic element 90 is in a naturally extended state, at which point the elastic element 90 does not store elastic potential energy, or the elastic element 90 is in a state of minimum energy storage, at which point the elastic element 90 stores the minimum elastic potential energy. When the trigger 80 continues to rotate, since the elastic potential energy stored in the elastic element 90 is insufficient to assist the movement of the trigger 80, the first triggering part 801 of the trigger 80 separates from the first actuating arm 901. The first actuating arm 901 abuts against the first limiting member 611, and the second triggering part 802 of the trigger 80 abuts against the second actuating arm 902. The second actuating arm 902 separates from the second limiting member 612 until the trigger 80 is in the second state, at which point the seat is in the unfolded state. After the elastic member 90 returns to its initial state, as the trigger member 80 continues to rotate to the second state, the second trigger part 802 acts on the second action arm 902, and the first action arm 901 is resisted by the first limit member 611. The elastic member 90 accumulates elastic potential energy again, which can be used to offset part of the gravitational potential energy when the seat body 100 flips downward, slowing down the downward flipping speed of the seat body 100 and providing buffer protection for the seat body 100.

[0071] It should be noted that when the trigger 80 switches from the second state to the first state, the motor 30 flips, driving the rotating shaft 20 and the trigger 80 to move in the opposite direction.

[0072] See Figure 6 and Figure 7 As shown, in some embodiments, the mounting bracket 61 is provided with a second mounting hole 613, and the rotating shaft 20 is rotatably connected to the mounting bracket 61 through the second mounting hole 613.

[0073] In some embodiments, the first limiting member 611 and the second limiting member 612 can be integrated onto the mounting bracket 61, or they can be components independent of the mounting bracket 61. The first limiting member 611 and the second limiting member 612 are respectively fixedly connected to the mounting bracket 61. (See reference...) Figure 9 As shown, the trigger 80 is disc-shaped, with a first trigger portion 801 and a second trigger portion 802 extending axially along the trigger 80 to minimize its weight. The trigger 80 has a third mounting hole 803, and a corresponding mounting block is provided on the rotating shaft 20. The cross-sectional shape of the mounting block matches the cross-sectional shape of the third mounting hole 803. The mounting block is fitted into the third mounting hole 803 of the trigger 80, allowing the trigger 80 and the rotating shaft 20 to rotate synchronously, preventing relative rotation between them. Optionally, the third mounting hole 803 is a square block, and the fixing block is square. The third mounting hole 803 can also be a rectangular hole, a triangular hole, etc.

[0074] In some embodiments, the elastic element 90 can be any elastic element, such as a torsion spring, tension spring, compression spring, or spiral spring, that can assist in the flipping process of the flipping mechanism 200 through the storage and release of elastic potential energy. Figure 11 The diagram shows the connection of a spiral spring in a tilting mechanism when the elastic element 90 is a spiral spring. Multiple spiral springs can be installed, sequentially sleeved on the rotating shaft 20 along its axial direction. The spiral springs are installed in opposite directions. Some spiral springs have their contacts connected to the first limiting member 611, while others have their contacts connected to the second limiting member 612. The inner coil of each spiral spring is connected to the rotating shaft. When the rotating shaft rotates, some spiral springs store energy, while others release energy to assist the rotation of the rotating shaft 20. Figure 11 As shown, when the rotating shaft 20 rotates counterclockwise, the spiral spring connected to the second limiting member 612 stores energy, and the spiral spring connected to the first limiting member 611 releases energy to assist the rotating shaft 20 in rotating.

[0075] See Figure 12 As shown, the output shaft of the motor 30 is provided with gear teeth to form the aforementioned transmission shaft, and the gear teeth on the motor output shaft mesh with the gear 50. The connector 10 is provided with a motor mounting hole, and the motor 30 is fixed to the connector 10 by a fixing nut 1023.

[0076] See Figure 13 and Figure 14 As shown, this utility model also provides a seat, including a seat body 100 and a flipping mechanism 200 as described above, wherein a connecting member 10 of the flipping mechanism 200 is connected to the seat body 100. The seat body 10 is flipped by rotating the connecting member 10 around a first axis.

[0077] See Figure 15 and Figure 16 As shown, the seat body 100 is divided into a first side seat body 1001 and a second side seat body 1002. The first side seat body 1001 and the second side seat body 1002 are connected by a connecting bracket 1003. The other side of the first side seat body 1001 is provided with a flipping mechanism 200, which is connected to the vehicle body through the flipping mechanism 200. The other side of the second side seat body 1002 is also provided with a flipping mechanism 200, which is connected to the vehicle body through the flipping mechanism 200. The first side seat body 1001 and the second side seat body 1002 can be flipped and stored or unfolded respectively through their respective flipping mechanisms 200. Figure 15 In the middle, the first side seat body 1001 is in the storage state, and the second side seat body 1002 is in the open state.

[0078] Taking the first side seat body 1001 being flipped upwards from a folded state to an unfolded state as an example, the working process of this utility model is explained as follows:

[0079] The motor 30 drives the drive shaft 40 to rotate, and the drive shaft 40 moves circumferentially along the gear 50. The connecting member 10 and the rotating shaft 20 follow the drive shaft 40 and move around the first axis of the rotating shaft 20, driving the first side seat body 1001 connected to the connecting member 10 to flip upward and unfold. During this process, the elastic potential energy accumulated by the elastic member 90 offsets part of the gravitational potential energy of the first side seat body 1001 as it flips upward, providing assistance for the upward flipping of the first side seat body 1001. When the first side seat body 1001 flips upward to the unfolded state, it accumulates elastic potential energy again to offset part of the gravitational potential energy of the first side seat body 1001 as it flips downward, providing cushioning protection for the downward flipping of the first side seat body 1001.

[0080] It should be noted that when the first side seat body 1001 needs to be flipped down from the unfolded state to the stored state, the rotation direction of the motor 30 is adjusted so that the drive shaft 40 rotates in the opposite direction.

[0081] In summary, this utility model embodiment provides a flipping mechanism and a seat, integrating the motor 30 onto the connector 10. The motor 30 transmits power through the meshing gear 50, achieving a speed reduction and torque increase effect, reducing the size of the motor 30, and reducing the installation space required by the motor 30. This reduces the space occupied by the motor 30 in the vehicle and improves the overall structural compactness of the flipping mechanism, further reducing its space occupation in the vehicle. Furthermore, a flipping assist component is provided on the flipping mechanism, providing dual assistance from the motor 30 and the elastic element 90 for the flipping of the seat body 100, making it easier to flip the six-part side of the split seat. The elastic element 90 also reduces the output power of the motor 30 during the flipping process.

[0082] 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.
