Description

Technical Field

[0001] This invention relates to the field of seating technology, and in particular to a storage device and a seat. Background Technology

[0002] With the development of the national economy and the gradual improvement of people's living standards, cars have gradually entered everyone's lives. As the user base expands, different needs for cars are gradually emerging. Some cars require storage and adjustment systems to store the backrests in order to expand the interior space.

[0003] Existing storage devices include a connector, a pivot, and a drive component. The connector is used to fix the backrest, one end of the pivot is fixedly connected to the connector, and the other end of the pivot is fixedly connected to the drive component, which drives the pivot to rotate. In this way, when an external force is applied to the backrest end to drive the pivot to rotate in order to adjust the backrest angle, the rotation of the pivot will pull the drive component in the opposite direction, causing the drive component to exert great resistance to the rotation of the pivot. This makes it difficult to adjust the backrest angle by applying external force to the backrest end, making it inconvenient to use. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides a storage device, including a rotating shaft, a connecting member, and a driving mechanism; the rotating shaft has a first axis, and includes a shaft body and a first abutting portion, the first abutting portion being fixedly connected to the outer wall of the shaft body, and the first abutting portion having a first abutting wall and a second abutting wall; the connecting member is fixedly connected to the shaft body; the driving mechanism includes a driving member, the driving member having a through hole, the shaft body passing through the through hole, the driving member having a first driving hole communicating with the through hole, the first driving hole having a first driving wall and a second driving wall, the first abutting portion passing through the first driving hole, the first driving wall and the first abutting wall facing each other, and the second driving wall and the second abutting wall facing each other; wherein... The driving member has a first state, a second state, and a third state. When the driving member is in the first state, the first driving wall abuts against the first abutting wall and can drive the rotating shaft to rotate around the first axis in a first direction, and there is a gap between the second driving wall and the second abutting wall. When the driving member is in the second state, there is a gap between the first driving wall and the first abutting wall, and there is a gap between the second driving wall and the second abutting wall. When the driving member is in the third state, the second driving wall abuts against the second abutting wall and can drive the rotating shaft to rotate around the first axis in a second direction, and there is a gap between the first driving wall and the first abutting wall, and the first direction and the second direction are opposite.

[0005] When the driving member is in the first state, the rotating shaft remains fixed, and the driving member rotates around the first axis in the second direction. The first driving wall will disengage from the first abutting wall, and the driving member will switch from the first state to the second state. The driving member continues to rotate around the first axis in the second direction, which will increase the gap between the first driving wall and the first abutting wall and decrease the gap between the second driving wall and the second abutting wall until the second driving wall abuts against the second abutting wall, and the driving member will switch from the second state to the third state. Similarly, when the driving member is in the third state, the rotating shaft remains fixed, and the driving member rotates around the first axis in the first direction, which can switch the driving member from the first state to the second state and from the second state to the third state.

[0007] In some embodiments, the first connecting wall is a first arc-shaped connecting wall, the second connecting wall is a second arc-shaped connecting wall, and the first arc-shaped connecting wall and the second arc-shaped connecting wall are in contact.

[0008] In some embodiments, the first abutting portion further includes a first arc-shaped transition wall and a second arc-shaped transition wall, wherein the first abutting wall is connected to the first connecting wall through the first arc-shaped transition wall, and the second abutting wall is connected to the first connecting wall through the second arc-shaped transition wall; the first driving hole further includes a third arc-shaped transition wall and a fourth arc-shaped transition wall, wherein the first driving wall is connected to the second connecting wall through the third arc-shaped transition wall, and the second driving wall is connected to the second connecting wall through the fourth arc-shaped transition wall.

[0009] In some embodiments, the rotating shaft further includes a second abutment portion, which is fixedly connected to the outer wall of the shaft body and is symmetrically arranged with respect to the center of the first abutment portion. The driving member has a second driving hole, which is connected to the through hole and is symmetrically arranged with respect to the center of the first driving hole. The second abutment portion passes through the second driving hole.

[0010] In some embodiments, the storage device further includes a mounting component and an elastic component. The mounting component includes a mounting bracket and a support rod. The mounting bracket has a mounting groove, the drive component is disposed in the mounting groove, the rotating shaft passes through the mounting bracket, and the support rod is connected to the mounting bracket and located on one side of the rotating shaft. The elastic component includes a first assist coil spring, which is disposed in the mounting groove. One end of the first assist coil spring is connected to the shaft body, and the other end of the first assist coil spring is connected to the support rod.

[0011] In some embodiments, the mounting component further includes an inner bracket disposed within the mounting groove; the mounting frame includes a first side plate, a bottom plate, and a second side plate, the first side plate being connected to one end of the bottom plate, the second side plate being connected to the end of the bottom plate away from the first side plate and disposed opposite to the first side plate, the mounting groove being formed between the first side plate, the bottom plate, and the second side plate, the two ends of the support rod being connected to the first side plate and the second side plate respectively, the inner bracket and the second side plate forming an accommodating groove, the driving member being disposed within the accommodating groove, and the elastic member being disposed between the inner bracket and the first side plate.

[0012] In some embodiments, the mounting component further includes a support plate, with its two ends connected to the first side plate and the second side plate, respectively, and the rotating shaft located between the support plate and the support rod; the elastic element further includes a second assisting coil spring, which is disposed in the mounting groove and located between the first assisting coil spring and the inner bracket, with one end of the second assisting coil spring connected to the shaft body and the other end of the second assisting coil spring connected to the support plate.

[0013] In some embodiments, the driving element is a first gear; the driving mechanism further includes a drive motor and a second gear, the drive motor having an output shaft, and the second gear being sleeved and fixed to the output shaft and meshing with the first gear.

[0014] The present invention also provides a seat, the seat including the storage device according to any one of the preceding claims.

[0015] Compared with the prior art, the storage device of this invention has the following advantages: When the driving member is in the first state, the driving member remains stationary. By inputting power at the end where the connecting member is located (i.e., the end where the backrest is located), the rotating shaft is driven to rotate around the first axis in the first direction S. The first abutting wall will disengage from the first driving wall, and the driving member will switch from the first state to the second state. As the rotating shaft continues to rotate around the first axis in the first direction, the gap between the first abutting wall and the first driving wall will increase, and the gap between the second abutting wall and the second driving wall will decrease. Before the second abutting wall abuts against the second driving wall (i.e., before the driving member switches from the second state), the device continues to rotate. Before switching to the third state, because there is a gap between the second abutment wall and the second drive wall, the rotation of the shaft around the first axis in the first direction will not drag the drive component in the opposite direction, and the drive component will not generate resistance to the rotation of the shaft. This allows power to be easily input at the end where the connector is located (i.e., the end where the backrest is located) to adjust the angle of the seat backrest around the first axis in the first direction, improving the flexibility of the seat backrest angle adjustment. Similarly, when the drive component is in the third state, the drive component remains stationary, and by inputting power at the end where the connector is located (i.e., the end where the backrest is located), the shaft is driven to rotate around the first axis in the second direction, which can... This increases the gap between the second abutment wall and the second drive wall and decreases the gap between the first abutment wall and the first drive wall. Before the first abutment wall abuts against the first drive wall (i.e., before the drive member switches from the second state to the first state), due to the gap between the first abutment wall and the first drive wall, the rotation of the shaft around the first axis in the second direction will not drag the drive member in the opposite direction, and the drive member will not generate resistance to the rotation of the shaft. This allows power to be easily input at the end where the connector is located (i.e., the end where the backrest is located) to adjust the angle of the seat backrest around the first axis in the second direction N, thus improving the adjustment of the seat backrest angle. Flexibility; In summary, the storage device provided by the present invention, by providing a first abutting part on the rotating shaft and a first driving hole on the driving member, can either place the driving member in a first state or a third state so that the driving wall of the first driving hole abuts against the abutting wall of the first abutting part, thereby realizing the backrest flipping storage function through the storage device, or place the driving member in a second state so that the driving wall of the first driving hole and the abutting wall of the first abutting part are spaced apart, so that when realizing the backrest angle adjustment function through the storage device, the rotating shaft can be prevented from dragging the driving member in the opposite direction, improving the flexibility of backrest angle adjustment and making it convenient to use.

[0043] In this application, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0044] like Figure 1-11 As shown, a preferred embodiment of the present invention provides a storage device comprising a rotating shaft 1, a connecting member 2, and a driving mechanism 3.

[0045] The rotating shaft 1 has a first axis 10. The rotating shaft 1 includes a shaft body 11 and a first abutting part 12. The first abutting part 12 is fixedly connected to the outer wall of the shaft body 11. The first abutting part 12 has a first abutting wall 121 and a second abutting wall 122. The connecting member 2 is fixedly connected to the shaft body 11. The driving mechanism 3 includes a driving member 31. The driving member 31 has a through hole 311. The shaft body 11 passes through the through hole 311. The driving member 31 has a first driving hole 312 that communicates with the through hole 311. The first driving hole 312 has a first driving wall 3121 and a second driving wall 3122. The first abutting part 12 passes through the first driving hole 312. The first driving wall 3121 and the first abutting wall 121 are opposite to each other. The second driving wall 3122 and the second abutting wall 122 are opposite to each other.

[0046] The driving member 31 has a first state, a second state, and a third state. When the driving member 31 is in the first state, the first driving wall 3121 abuts against the first abutting wall 121 and can drive the rotating shaft 1 to rotate around the first axis 10 in the first direction S. There is a gap between the second driving wall 3122 and the second abutting wall 122. When the driving member 31 is in the second state, there is a gap between the first driving wall 3121 and the first abutting wall 121, and there is a gap between the second driving wall 3122 and the second abutting wall 122. When the driving member 31 is in the third state, the second driving wall 3122 abuts against the second abutting wall 122 and can drive the rotating shaft 1 to rotate around the first axis 10 in the second direction N. There is a gap between the first driving wall 3121 and the first abutting wall 121, and the first direction S and the second direction N are opposite.

[0047] Based on this technical solution, when the driving member 31 is in the first state, the driving member 31 remains stationary. By inputting power to the end where the connecting member 2 is located (i.e., the end where the backrest is located), the rotating shaft 1 is driven to rotate around the first axis 10 in the first direction S. The first abutment wall 121 will disengage from the first driving wall 3121, causing the driving member 31 to switch from the first state to the second state. The rotating shaft 1 continues to rotate around the first axis 10 in the first direction S, which will increase the gap between the first abutment wall 121 and the first driving wall 3121 and decrease the gap between the second abutment wall 122 and the second driving wall 3122. Before the second abutment wall 122 abuts against the second driving wall 3122 (i.e., before the driving member 31 switches from the second state to the third state), Before the third state, because there is a gap between the second abutment wall 122 and the second drive wall 3122, the rotation of the shaft 1 around the first axis 10 in the first direction S will not drag the drive member 31 in the opposite direction, and the drive member 31 will not generate resistance to the rotation of the shaft 1. This allows for easy adjustment of the seat back angle by inputting power at the end where the connector 2 is located (i.e., the end where the backrest is located) around the first axis 10 in the first direction S, thus improving the flexibility of the seat back angle adjustment. Similarly, when the drive member 31 is in the third state, the drive member 31 remains stationary. By inputting power at the end where the connector 2 is located (i.e., the end where the backrest is located), the shaft 1 is driven to rotate around the first axis 10 in the second direction N, which can increase the second... The gap between the abutment wall 122 and the second drive wall 3122 is reduced, and the gap between the first abutment wall 121 and the first drive wall 3121 is decreased. Before the first abutment wall 121 abuts against the first drive wall 3121 (i.e., before the drive member 31 switches from the second state to the first state), because there is a gap between the first abutment wall 121 and the first drive wall 3121, the rotation of the shaft 1 around the first axis 10 in the second direction N will not drag the drive member 31 in the opposite direction. The drive member 31 will not generate resistance to the rotation of the shaft 1, thereby making it easy to input power at the end where the connector 2 is located (i.e., the end where the backrest is located) to adjust the angle of the seat backrest around the first axis 10 in the second direction N, thereby improving the seat's position. The backrest angle adjustment flexibility is improved. In summary, the storage device provided by the present invention provides a first abutting part 12 on the rotating shaft 1 and a first driving hole 312 on the driving member 31. It can either place the driving member 31 in a first state or a third state so that the driving wall of the first driving hole 312 abuts against the abutting wall of the first abutting part 12, thereby realizing the backrest flipping and storage function through the storage device, or place the driving member 31 in a second state so that the driving wall of the first driving hole 312 and the abutting wall of the first abutting part 12 are spaced apart. This avoids the rotating shaft dragging the driving member in the opposite direction when the backrest angle is adjusted through the storage device, thus improving the backrest angle adjustment flexibility and making it convenient to use.

[0048] When the drive member 31 is in the first state, the rotating shaft 1 remains fixed, and the drive member 31 rotates around the first axis 10 in the second direction N. The first drive wall 3121 will disengage from the first abutment wall 121, and the drive member 31 will switch from the first state to the second state. The drive member 31 continues to rotate around the first axis 10 in the second direction N, which will increase the gap between the first drive wall 3121 and the first abutment wall 121 and decrease the gap between the second drive wall 3122 and the second abutment wall 122, until the second drive wall 3122 abuts against the second abutment wall 122, and the drive member 31 switches from the second state to the third state. Similarly, when the drive member 31 is in the third state, the rotating shaft 1 remains fixed, and the drive member 31 rotates around the first axis 10 in the first direction S, which can switch the drive member 31 from the first state to the second state and from the second state to the third state.

[0049] In this embodiment, the first abutting part 12 is integrally formed on the outer wall of the shaft body 11.

[0050] In this embodiment, the first axis 10 is the central axis of the rotating shaft 1.

[0051] In this embodiment, the first direction S is clockwise and the second direction N is counterclockwise.

[0052] In some other implementations, the first direction S can be set to be counterclockwise and the second direction N to be clockwise, which is not limited here.

[0053] See Figures 1-3 ,and Figure 8 The storage device provided in this embodiment of the invention further includes a mounting component 4 and an elastic component 5. The mounting component 4 includes a mounting frame 41 and a support rod 42. The mounting frame 41 has a mounting groove 410, a driving component 31 is disposed in the mounting groove 410, a rotating shaft 1 passes through the mounting frame 41, and the support rod 42 is connected to the mounting frame 41 and located on one side of the rotating shaft 1. The elastic component 5 includes a first assist coil spring 51, which is disposed in the mounting groove 410. One end of the first assist coil spring 51 is connected to the shaft body 11, and the other end of the first assist coil spring 51 is connected to the support rod 42. By placing the driving component 31 in the mounting groove 410, the side wall of the mounting groove 410 can shield and protect the driving component 31. The first assist coil spring 51 can not only offset part of the gravity of the backrest when it is flipped down, but also provide cushioning, so that the backrest can be stored and reclined more smoothly. It can also counteract part of the gravity when the backrest is raised by driving it to flip upward through the pivot 1 and the connector 2, thereby reducing the power required to flip the backrest upward and reducing the load on the drive mechanism 3.

[0054] Mounting component 4 also includes an inner bracket 43, which is disposed within the mounting groove 410.

[0055] Mounting bracket 41 includes a first side plate 411, a bottom plate 412, and a second side plate 413. The first side plate 411 is connected to one end of the bottom plate 412, and the second side plate 413 is connected to the end of the bottom plate 412 away from the first side plate 411 and is disposed opposite to the first side plate 411. A mounting groove 410 is formed between the first side plate 411, the bottom plate 412, and the second side plate 413. The two ends of the support rod 42 are respectively connected to the first side plate 411 and the second side plate 413. An accommodating groove 430 is formed between the inner bracket 43 and the second side plate 413. A driving member 31 is disposed in the accommodating groove 430, and an elastic member 5 is disposed between the inner bracket 43 and the first side plate 411. The inner bracket 43 is placed in the mounting groove 410 and forms a receiving groove 430 with the second side plate 413. The elastic element 5 and the driving element 31 can be separated in the mounting groove 410 to avoid direct contact between the elastic element 5 and the driving element 31, thereby preventing interference between the elastic element 5 and the driving element 31. It can also improve the overall strength of the mounting bracket 41 and improve the safety and reliability of the storage device.

[0056] Mounting component 4 also includes a support plate 44, with the first side plate 411 and the second side plate 413 connected to the two ends of the support plate 44 respectively, and the rotating shaft 1 located between the support plate 44 and the support rod 42.

[0057] The elastic element 5 also includes a second assist spring 52, which is disposed within the mounting groove 410 and located between the first assist spring 51 and the inner bracket 43. One end of the second assist spring 52 is connected to the shaft body 11, and the other end is connected to the support plate 44. Thus, the second assist spring 52 and the support plate 44 can cooperate with the first assist spring 51 and the support rod 42 to achieve bidirectional buffering during the backrest flipping process, thereby balancing the force during the backrest flipping and making the backrest more stable and improving safety.

[0058] In this embodiment, there are two first assist coil springs 51.

[0059] In some other embodiments, the number of first assist coil springs 51 can also be any number, such as one, three, four, etc.

[0060] In this embodiment, there is one second assist coil spring 52.

[0061] In some other embodiments, the number of second assist coil springs 52 can also be any number, such as two, three, or four.

[0062] The storage device also includes a sound-dampening component 6, which comprises a first felt 61, a second felt 62, and a third felt 63. The first felt 61 is disposed between the first assist spring 51 and the first side plate 411, the second felt 62 is disposed between the first assist spring 51 and the second assist spring 52, and the third felt 63 is disposed between the second assist spring 52 and the inner support 43. The sound-dampening component 6 eliminates the abnormal noise generated by the interaction of the springs during operation.

[0063] See Figures 1-3 ,and Figures 6-7 The driving component 31 provided in this embodiment of the invention is a first gear; the driving mechanism 3 also includes a driving motor 32 and a second gear 33. The driving motor 32 has an output shaft 321, and the second gear 33 is sleeved and fixed to the output shaft 321 and meshes with the first gear. In this way, the driving motor 32 drives the second gear 33 to rotate, which in turn drives the first gear to rotate. Thus, different gear ratios can be designed as needed to adapt to different backrest flipping speeds and torque requirements, providing high flexibility.

[0064] See Figures 1-7 ,and Figures 9-14 The first abutting part 12 also has a first connecting wall 123, with the first abutting wall 121 and the second abutting wall 122 respectively connected to the two ends of the first connecting wall 123; the first driving hole 312 has a second connecting wall 3123 opposite to the first connecting wall 123, with the first driving wall 3121 and the second driving wall 3122 respectively connected to the two ends of the second connecting wall 3123.

[0065] In this embodiment, the first abutting wall 121 has a planar structure, the second abutting wall 122 has a planar structure, the first driving wall 3121 has a planar structure, and the second driving wall 3122 has a planar structure.

[0066] Preferably, the first connecting wall 123 is a first arc-shaped connecting wall, and the second connecting wall 3123 is a second arc-shaped connecting wall, with the first and second arc-shaped connecting walls in contact. This arrangement of the first and second arc-shaped connecting walls in contact allows for rapid assembly and positioning of the first abutment 12 and the driving component 31 during assembly of the rotating shaft 1 and the driving component 31, reducing assembly difficulty. Furthermore, during the relative rotation of the driving component 31 and the rotating shaft 1 (i.e., during the switching between the first, second, and third states of the driving component 31), the second arc-shaped connecting wall guides and limits the first arc-shaped connecting wall, ensuring the precise position of the first abutment 12 in the first driving hole 312 and improving the consistency of movement between the driving component 31 and the rotating shaft 1.

[0067] The first abutment portion 12 further includes a first arc-shaped transition wall 124 and a second arc-shaped transition wall 125. The first abutment wall 121 is connected to one end of the first connecting wall 123 through the first arc-shaped transition wall 124, and the second abutment wall 122 is connected to the other end of the first connecting wall 123 through the second arc-shaped transition wall 125. By using the first arc-shaped transition wall 124 and the second arc-shaped transition wall 125, stress concentration at the connection position between the abutment wall and the first connecting wall 123 can be reduced, thereby improving the durability of the first abutment portion 12. It can also prevent the formation of sharp features at the connection position between the abutment wall and the first connecting arm, thereby preventing the first abutment portion 12 from scratching the wall of the first driving hole 312.

[0068] The first driving hole 312 also has a third arc-shaped transition wall 3124 and a fourth arc-shaped transition wall. The first driving wall 3121 is connected to one end of the second connecting wall 3123 through the third arc-shaped transition wall 3124, and the second driving wall 3122 is connected to the other end of the second connecting wall 3123 through the fourth arc-shaped transition wall 3125. By using the third arc-shaped transition wall 3124 and the fourth arc-shaped transition wall 3125, stress concentration at the connection position between the driving wall and the first connecting wall 123 can be reduced, thereby improving the durability of the driving component 31.

[0069] The rotating shaft 1 also includes a second abutment portion 13, which is fixedly connected to the outer wall of the shaft body 11 and symmetrically arranged with respect to the first abutment portion 12. The driving member 31 has a second driving hole 313, which is connected to the through hole 311 and symmetrically arranged with respect to the first driving hole 312. The second abutment portion 13 passes through the second driving hole 313. Thus, when the driving wall of the first driving hole 312 abuts against the abutment wall of the first abutment portion 12, the driving wall of the second driving hole 313 also abuts against the abutment wall of the second abutment wall 122. This allows the driving member 31 to transmit torque evenly and balancedly to the rotating shaft 1 and drive the rotating shaft 1 to rotate, avoiding vibration and wear caused by imbalance during rotation of the rotating shaft 1, thereby enhancing the stability and reliability of the connection between the driving member 31 and the rotating shaft 1.

[0070] In this embodiment, the second abutment portion 13 is integrally formed on the outer wall of the shaft body 11.

[0071] See Figures 9-14 In the second state, the driving member 31 has a preset position. From this preset position, the driving member 31 rotates a first predetermined angle α around the first axis 10 along the first direction S, thereby abutting the first driving wall 3121 against the first abutting wall 121, thus switching the driving member 31 from the second state to the first state. From this preset position, the driving member 31 rotates a second predetermined angle b around the first axis 10 along the second direction N, thereby abutting the second driving wall 3122 against the second abutting wall 122, thus switching the driving member 31 from the second state to the third state.

[0072] The maximum free travel angle c = a + b of the rotating shaft 1 rotating around the first axis 10 without dragging the driving component 31 in the reverse direction is exemplarily, when the driving component 31 is in the first state, the driving component 31 is kept stationary, and power is input at the end where the connecting member 2 is located (i.e., the end where the backrest is located) to drive the rotating shaft 1 to rotate around the first axis 10 in the first direction S to the maximum free travel angle c, which will not cause the rotating shaft 1 to drag the driving component 31 in the reverse direction; when the driving component 31 is in the preset position of the second state, the driving component 31 is kept stationary, and power is input at the end where the connecting member 2 is located (i.e., the end where the backrest is located) to drive the rotating shaft 1 to rotate around the first axis 10 in the first direction S to the first predetermined angle a. The shaft 1 will not drag the drive component 31 in the reverse direction. When power is input at the end of the connector 2 (i.e., the end of the backrest) to drive the shaft 1 to rotate around the first axis 10 in the second direction N by a second predetermined angle b, the shaft 1 will not drag the drive component 31 in the reverse direction. When the drive component 31 is in the third state, keeping the drive component 31 fixed, and inputting power at the end of the connector 2 (i.e., the end of the backrest) to drive the shaft 1 to rotate around the first axis 10 in the second direction N by a maximum idle stroke angle c, the shaft 1 will not drag the drive component 31 in the reverse direction.

[0073] Preferably, 5°≤a≤30°.

[0074] In this embodiment, a = 15°.

[0075] In some other embodiments, the first predetermined angle α can be any angle value such as 5°, 8°, 10°, 20°, 25°, 30°, etc.

[0076] Preferably, 5°≤b≤30°.

[0077] In this embodiment, b = 15°, i.e., c = 30°.

[0078] In some other embodiments, the second predetermined angle b can be any angle value such as 5°, 8°, 10°, 20°, 25°, 30°, etc.

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 invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
