Description

Technical Field

[0001] The present invention relates to the technical field of vehicle seats, and particularly to a seat rotation mechanism for a vehicle. The present invention also relates to a vehicle provided with the seat rotation mechanism. Background Art

[0002] Traditional vehicle seats generally do not have a rotation function. When there is insufficient space for the occupant to enter and exit the vehicle compartment, the space can only be adjusted by moving the seat back and forth along the slide rail under the seat, lacking convenience for occupants who have difficulty entering and exiting the vehicle compartment.

[0003] Currently, although vehicle seats with a rotation function have begun to appear on the market, these vehicle seats have the following technical problems:

[0004] Firstly, since the more electric functions the entire vehicle seat has, the more wiring harnesses are required, and the space available for arranging the wiring harness provided by the rotation mechanism is very limited, there is a risk of wiring harness entanglement during use.

[0005] Secondly, the motors of the electric slide rail and the rotation mechanism are both arranged in the middle, resulting in easy interference between the slide rail motor and the rotation mechanism motor.

[0006] Thirdly, in order to avoid interference between the slide rail motor and the rotation mechanism motor, a large Z - direction space needs to be ensured during installation. When the Z - direction height of the rotation mechanism cannot be reduced, the height of the entire vehicle seat can only be increased forcedly. Summary of the Invention

[0043] To enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0044] In this article, terms such as "upper, lower, inner, outer" are established based on the positional relationship shown in the drawings. Depending on the different drawings, the corresponding positional relationship may also change accordingly. Therefore, it cannot be understood as an absolute limitation of the protection scope; moreover, relational terms such as "first" and "second" are only used to distinguish one component with the same name from another, and do not necessarily require or imply any such actual relationship or order between these components.

[0045] Please refer to Figure 1 、 Figure 2 、 Figure 3 , Figure 1 is an axonometric view of a seat rotation mechanism provided by an embodiment of the present invention; Figure 2 is Figure 1 Top view of the shown seat rotation mechanism; Figure 3 is Figure 2 Schematic diagram of the shown seat rotation mechanism after removing the rotating plate

[0046] In a specific embodiment, the seat rotation mechanism provided by the present invention mainly consists of an outer slide rail 1, an inner slide rail 2, and a rotation mechanism. The rotation mechanism further consists of a rotation plate 3, a link mechanism, and an auxiliary rotation mechanism. Among them, the rotation plate 3 is used to carry the seat, and the link mechanism and the auxiliary rotation mechanism are used to connect the rotation plate 3 to the outer slide rail 1 and the inner slide rail 2.

[0047] The rotation plate 3 is hinged to the outer slide rail 1 through a hinge shaft to form a main rotation point 6. The link mechanism has a first link 4 and a second link 5. The first link 4 is the active part that pulls the rotation plate 3 to rotate. The first link 4 is fixed to the inner slide rail 2 and is hinged to the second link 5 through a first hinge point 7. The second link 5 is hinged to the rotation plate 3 through a second hinge point 8.

[0048] The structure of the hinge point can have various forms. In this embodiment, the first hinge point 7 and the second hinge point 8 can be connected by a stepped bolt to form a rotary joint (the same below).

[0049] Specifically, the first link 4 extends obliquely forward from the inner slide rail 2, and the second link 5 extends obliquely backward from the front end of the first link 5. The included angle between the first link 4 and the second link 5 is an inverted "V" shape with the opening facing the rear side.

[0050] To ensure the stability of the seat rotation, the rotation mechanism is also provided with an auxiliary rotation mechanism. The auxiliary rotation mechanism mainly consists of a first bracket 9, a second bracket 10, and a third bracket 11. Among them, the first bracket 9 is generally in a "T" shape. It is fixed to the outer slide rail 1 and is located on the front side of the main rotation point 6. The first bracket 9 is provided with a first arc-shaped chute 91 centered on the main rotation point 6. The rotation plate 3 is fixed with a stepped bolt and is slidably matched with the first arc-shaped chute 91 through the stepped bolt to form a first auxiliary rotation point 12, that is, the rotation plate 3 moves in the first arc-shaped groove 91 of the first bracket 9 through the stepped bolt (the same below).

[0051] It should be noted here that the maximum rotation angle of the rotation plate 3 in this embodiment is 45°. Therefore, the first bracket 9 is designed to exceed the outer slide rail 1. It can be understood that when the rotation angle of the rotation mechanism is less than 45°, the first bracket 9 can be designed not to exceed the outer slide rail 1. Moreover, for different rotation angles, the first bracket 9 can also be designed in a non-"T" shape.

[0052] The second bracket 10 is fixed to the outer slide rail 1 and is located at the rear side of the first bracket 9. The second bracket 10 is generally fan-shaped and extends from the outer slide rail 1 to the area between the outer slide rail 1 and the inner slide rail 2. The main rotation point 6 is located at the root 10 of the second bracket. A second arc-shaped chute 101 with the main rotation point 6 as the center of the circle is provided on the second bracket 10. The rotating plate 3 is slidably engaged with the second arc-shaped chute 101 through the second auxiliary rotation point 13. Moreover, the second hinge point 8 coincides with the second auxiliary rotation point 13, that is to say, the step bolt used to form the second hinge point 8 and the second auxiliary rotation point 13 is the same bolt.

[0053] The third bracket 11 is fixed to the inner slide rail 2 and is located at the front side of the first connecting rod 4. It extends horizontally from the inner slide rail 2 to the outer slide rail 1. A curved chute 111 is provided on the third bracket 11. The rotating plate 3 is slidably engaged with the curved chute 111 through the third auxiliary rotation point 14. Since the third auxiliary rotation point 14 gradually moves away from the main rotation point 6 during the rotation of the seat, therefore, the curved chute 111 is not an arc with the main rotation point 6 as the center of the circle, but is designed in a form where the curvature gradually decreases from the root to the end.

[0054] The connecting lines of the above-mentioned main rotation point 6, second hinge point 8, first auxiliary rotation point 12, and third auxiliary rotation point 14 are generally in the shape of a parallelogram.

[0055] A hole position 31 is provided in the middle of the rotating plate 3. The size of the hole position 31 can be designed to be relatively large, which can provide sufficient space for wiring harness arrangement, thus avoiding the problem of wire winding.

[0056] Four connection points 32 for connecting the seat are provided at the four corners of the rotating plate 3. The main rotation point 6, second hinge point 8 (coinciding with the second auxiliary rotation point), first auxiliary rotation point 12, and third auxiliary rotation point 14 are located in the internal area defined by the four connection points 32. Deburring parts 33 that avoid the connection points 32, main rotation point 6, second hinge point 8, first auxiliary rotation point 12, and third auxiliary rotation point 14 are provided on both sides of the rotating plate 3. Thus, on the premise of ensuring the structural strength, the weight of the rotating plate is reduced as much as possible, and the interference between the rotating plate 3 and other components is avoided.

[0057] Please refer to Figure 4 , Figure 4 For Figure 2 the schematic diagram of the seat rotation mechanism when it is at the maximum rotation angle as shown.

[0058] Under normal circumstances, the outer slide rail 1 and the inner slide rail 2 move at the same speed, which is mainly used to drive the seat to move forward and backward to adjust the space between the front row and the rear row.

[0059] When the seat needs to be rotated, since the outer slide rail 1 and the inner slide rail 2 can be driven to run separately, by controlling the movement speed of the inner slide rail 2 to be greater than that of the outer slide rail 1, the first link 4 moves forward, and the angle between the first link 4 and the second link 5 becomes larger. The rotation plate 3 is driven to rotate leftward around the main rotation point 6 through the second hinge point 8 until the rotation plate 3 rotates to 45 degrees.

[0060] For the control method, the outer slide rail 1 can also remain stationary while the inner slide rail 2 moves forward to generate a speed difference. Or the inner slide rail 2 can remain stationary while the outer slide rail 1 moves backward to generate a speed difference. Or the outer slide rail 1 and the inner slide rail 2 move backward simultaneously, but the speed of the outer slide rail 1 is greater than that of the inner slide rail, etc. All these control methods can drive the rotation 3 to rotate. Moreover, according to actual needs, the rotation angle of the rotation plate 3 can also be less than 45 degrees.

[0061] Please refer to Figure 5 、 Figure 6 、 Figure 7 , Figure 5 which is an axonometric view of another seat rotation mechanism provided by an embodiment of the present invention; Figure 6 is Figure 5 the top view of the seat rotation mechanism shown in Figure 7 is Figure 6 the schematic diagram of the seat rotation mechanism shown in

[0062] In another specific embodiment, the seat rotation mechanism provided by the present invention mainly consists of an outer slide rail 1, an inner slide rail 2, and a rotation mechanism, etc. The rotation mechanism further consists of a rotation plate 3, a link mechanism, and an auxiliary rotation mechanism. Among them, the rotation plate 3 is used to carry the seat, and the link mechanism and the auxiliary rotation mechanism are used to connect the rotation plate 3 with the outer slide rail 1 and the inner slide rail 2.

[0063] The rotation plate 3 is hinged to the outer slide rail 1 through a hinge shaft to form a main rotation point 6. The link mechanism mainly consists of a main push rod 15, a first link 4, and a second link 5.

[0064] The main push rod 15 is the active part that pushes the rotation plate 3 to rotate. It is fixed to the inner slide rail 2 and extends laterally from the inner slide rail to the outer slide rail 1. The main push groove 34 on the rotation plate 3 is a linearly extending straight groove. The main push rod 15 is slidably matched with the main push groove 34 on the rotation plate 3 through a main push point 16.

[0065] The first link 4 is fixed to the inner slide rail 2 and is located on the front side of the main push rod 15. The length of the first link 4 is greater than that of the main push rod 15. The first link 4 extends laterally from the inner slide rail 2 towards the outer slide rail 1. The second link 5 extends obliquely forward from the front end of the first link 4. The first link 4 is hinged to the second link 5 through the first hinge point 7, and the second link 5 is hinged to the rotating plate 3 through the second hinge point 8. In the initial state, the included angle between the first link 4 and the second link 5 is in a "V" shape with the opening facing the inner slide rail 2.

[0066] To ensure the stability of the seat rotation, the rotation mechanism is also provided with an auxiliary rotation mechanism. The auxiliary rotation mechanism is provided with a first bracket 9. The first bracket 9 is fixed to the outer slide rail 1 and is located on the front side of the main rotation point 16. The first bracket 9 is generally in a "T" shape, and is provided with a first arc-shaped chute 91 centered on the main rotation point 6, and the first arc-shaped chute 91 straddles the outer slide rail 1 laterally. The rotating plate 3 is slidably engaged with the first arc-shaped chute 91 through the first auxiliary rotation point 12.

[0067] In the initial state, the connecting lines of the above-mentioned main rotation point 6, main push point 16, second hinge point 8, and first auxiliary rotation point 12 are generally in a parallelogram shape.

[0068] A hole 31 is provided in the middle of the rotating plate 3. The size of the hole 31 can be designed relatively large, which can provide sufficient space for wire harness layout, thus avoiding the problem of wire winding.

[0069] Four connection points 32 for connecting the seat are provided at the four corners of the rotating plate 3. The main rotation point 6, main push point 16, second hinge point 8, and first auxiliary rotation point 12 are located in the internal area defined by the four connection points 32. Deburring parts 33 that avoid the connection points 32, main rotation point 6, main push point 16, second hinge point 8, and first auxiliary rotation point 12 are provided on both sides of the rotating plate 3. Thus, on the premise of ensuring the structural strength, the weight of the rotating plate is reduced as much as possible, and interference between the rotating plate 3 and other components is avoided.

[0070] Please refer to Figure 8 , Figure 8 For Figure 6 the schematic diagram when the seat rotation mechanism shown is at the maximum rotation angle.

[0071] Under normal circumstances, the outer slide rail 1 and the inner slide rail 2 move at the same speed, which is mainly used to drive the seat to move back and forth to adjust the space between the front row and the back row.

[0072] When the seat needs to be rotated, since the outer slide rail 1 and the inner slide rail 2 can be driven and operated separately, by controlling the movement speed of the inner slide rail 2 to be greater than that of the outer slide rail 1, the main push rod 15 moves forward, and the main push point 16 starts to slide along the main push groove 34. At the same time, the included angle between the first connecting rod 4 and the second connecting rod 5 becomes larger, driving the rotating plate 3 to rotate counterclockwise around the main rotation point 6 through the second hinge point 8 until the rotating plate 3 rotates to 45 degrees.

[0073] For the control method, the outer slide rail 1 can also remain stationary while the inner slide rail 2 moves forward to generate a speed difference. Or the inner slide rail 2 can remain stationary while the outer slide rail 1 moves backward to generate a speed difference. Or the outer slide rail 1 and the inner slide rail 2 move backward simultaneously, but the speed of the outer slide rail 1 is greater than that of the inner slide rail, etc. All these control methods can drive the rotation of the rotating plate 3. Moreover, according to actual needs, the rotation angle of the rotating plate 3 can also be less than 45 degrees.

[0074] It should be noted here that for the seat rotation mechanism at the driver's position, since the seat needs to rotate counterclockwise, the left slide rail under the seat is the outer slide rail 1, and the right slide rail is the inner slide rail 2. For the seat rotation mechanism at the passenger's position, since the seat needs to rotate clockwise, the left slide rail under the seat is the inner slide rail 2, and the right slide rail is the outer slide rail 1. That is, the seat rotation mechanisms at the driver's position and the passenger's position are in a mirror-symmetrical relationship.

[0075] The above embodiments are only the preferred solutions of the present invention, and are not specifically limited thereto. On this basis, targeted adjustments can be made according to actual needs to obtain different implementation manners. For example, the first connecting rod 4 in the first embodiment can also extend horizontally, or the root of the second bracket 10 in the first embodiment can also avoid the main rotation point 6, or the second hinge point 8 and the second auxiliary rotation point 13 in the first embodiment can also not coincide, or the second connecting rod 5 in the second embodiment extends obliquely forward, etc. Since there are many possible implementation manners, they will not be listed one by one here.

[0076] In addition to the above seat rotation mechanism, the present invention also provides an automobile, which can specifically be a fuel vehicle, a new energy vehicle or a hybrid vehicle. It has a vehicle body and an automobile seat located inside the vehicle body, and the automobile seat is installed inside the vehicle body through the seat rotation mechanism described above. There are two structures for the connection between the rotating plate 3 and the seat, and both can reserve interfaces. One structure is that the rotating plate 3 is directly connected to the seat seat pan, and the other structure is that a transverse slide rail is added between the rotating plate 3 and the seat seat pan, so that the seat can be adjusted both front and back and left and right. For the remaining structures of the automobile, please refer to the prior art and will not be elaborated herein.

[0077] The above has introduced in detail the seat rotation mechanism and the vehicle provided by the present invention. Specific examples are used in this article to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the core idea of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can still be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
