The positive direction of the X-axis represents the front of the vehicle, and the reverse direction of the X-axis represents the rear of the vehicle. The Y-axis represents the left-right direction of the vehicle.

The positive direction of the Z-axis represents the upper part of the vehicle, and the reverse direction of the Z-axis represents the lower part of the vehicle. It should be noted that the meanings represented by the foregoing X-axis, Y-axis, and Z-axis are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0034] As Figures 1-5 shown, a seat adjustment device according to an embodiment of the present utility model includes a first slide rail assembly 1, a second slide rail assembly 2, and a turntable assembly 3. The first slide rail assembly 1 is arranged to extend along a first direction. The second slide rail assembly 2 is arranged to extend along a second direction. The first direction and the second direction are arranged perpendicular to each other. Both the first slide rail assembly 1 and the second slide rail assembly 2 include a first track 41 and a second track 42 that are relatively slidably arranged. The turntable assembly 3 includes a first turntable 31 and a second turntable 32 that are relatively rotatably arranged. The first track 41 of the first slide rail assembly 1 is used to connect with the vehicle floor. The second track 42 of the first slide rail assembly 1 is fixedly connected to the first track 41 of the second slide rail assembly 2. The second track 42 of the second slide rail assembly 2 is fixedly connected to the first turntable 31. The second turntable 32 is used to rotate relative to the first turntable 31, and the second turntable 32 is used to connect with the seat body.

[0035] Specifically, one of the first slide rail assembly 1 and the second slide rail assembly 2 is arranged to extend along the front-back direction of the vehicle, and the other is arranged to extend along the left-right direction of the vehicle. That is, the first direction can be the front-back direction of the vehicle, and the second direction is the left-right direction of the vehicle, or the first direction is the left-right direction of the vehicle, and the second direction is the front-back direction of the vehicle. For the convenience of description, hereinafter, an example is given in which the first slide rail assembly 1 extends along the front-back direction of the vehicle, that is, the direction indicated by the X-axis, and the second slide rail assembly 2 extends along the left-right direction of the vehicle, that is, the direction indicated by the Y-axis. The extension direction of the second track 42 of the first slide rail assembly 1 is the same as that of the first track 41, both being the direction indicated by the X-axis. The extension direction of the second track 42 of the second slide rail assembly 2 is the same as that of the first track 41, both being the direction indicated by the Y-axis. The first slide rail assembly 1, the second slide rail assembly 2, and the turntable assembly 3 can be sequentially arranged in the order from bottom to top.

[0036] The first turntable 31 and the second turntable 32 of the turntable assembly 3 can both be plate-like structures arranged horizontally. The second turntable 32 is arranged above the first turntable 31, and the second turntable 32 can rotate relative to the first turntable 31 around the Z-axis.

[0037] It should be noted that the "fixed connection" mentioned in the present utility model means that the relative positions of two connected structures are fixed and no relative movement can occur between them.

[0038] In this embodiment, the first track 41 of the first slide rail assembly 1 can be fixed to the vehicle floor by bolts. The second track 42 of the first slide rail assembly 1 slides relative to the first track 41 to drive the second slide rail assembly 2, the turntable assembly 3 and the seat body to move forward or backward of the vehicle (as Figures 6-8 shown), and the second track 42 of the second slide rail assembly 2 slides relative to the first track 41 to drive the turntable assembly 3 and the seat body to move left or right of the vehicle (as Figures 9-10 ), and the second turntable 32 of the turntable assembly 3 rotates relative to the first turntable 31 in the horizontal plane to drive the seat body to rotate horizontally. It can be seen that the seat adjusting device can realize the movement of the seat body in multiple different directions of moving forward and backward, left and right, and horizontal rotation in the vehicle. The adjustment method of the seat body is diversified, and it can be flexibly adjusted according to actual needs, so as to make full use of the interior space of the vehicle and better meet the use needs in different occasions.

[0039] Optionally, the first direction is the front-back direction of the vehicle, the second direction is the left-right direction of the vehicle, the two first slide rail assemblies 1 are arranged at intervals in the left-right direction of the vehicle, the two second slide rail assemblies 2 are arranged at intervals in the front-back direction of the vehicle and both ends are respectively located on the two first slide rail assemblies 1, and the first slide rail assembly 1, the second slide rail assembly 2 and the turntable assembly 3 are arranged in sequence from below the vehicle to above the vehicle.

[0040] In this embodiment, the two first slide rail assemblies 1 are arranged opposite to each other in the left-right direction of the vehicle, the two second slide rail assemblies 2 are arranged opposite to each other in the front-back direction of the vehicle, and the two first slide rail assemblies 1 and the two second slide rail assemblies 2 enclose a frame structure, which improves the support stability for the turntable assembly 3 and the seat body and makes the movement adjustment of the seat body more stable.

[0041] As Figure 2 shown, optionally, the seat adjusting device further includes a first driving mechanism 5. The first driving mechanism 5 is arranged between the two first slide rail assemblies 1. The first driving mechanism 5 includes a rotary driving part 51 and an output shaft 52. The rotary driving part 51 is respectively connected with the output shaft 52 at both ends in the left-right direction of the vehicle, and the two output shafts 52 are respectively drivingly connected with the two first slide rail assemblies 1 through a first rotation-to-linear transmission structure for driving the second track 42 of the first slide rail assembly 1 to move relative to the first track 41.

[0042] In this embodiment, the first driving mechanism 5 can be a rotary driving motor. The rotary driving part 51 of the first driving mechanism 5 provides a rotary driving force around the Y-axis. Two output shafts 52 are provided and both extend along the direction shown by the Y-axis. The rotary driving part 51 is located between the two first slide rail assemblies 1, and the two ends of the rotary driving part 51 in the Y direction are respectively connected to the second tracks 42 of the corresponding first slide rail assemblies 1 through the corresponding output shafts 52. The rotary driving part 51 drives the output shafts 52 to rotate around their own axes. Two first rotation-to-linear transmission structures are provided and are respectively located inside the corresponding first slide rail assemblies 1. Each rotation-to-linear transmission structure is connected to the first track 41 and / or the second track 42 of the corresponding first slide rail assembly 1. The two output shafts 52 are respectively connected to the corresponding first slide rail assemblies 1 through the corresponding first rotation-to-linear transmission structures. The rotary driving force of the output shafts 52 is converted into a linear driving force through the first rotation-to-linear transmission structures to drive the first track 41 of the first slide rail assembly 1 to move back and forth relative to the second track 42, and then drive the seat body to move back and forth along the vehicle. Here, the first rotation-to-linear transmission structure can be a gear-rack assembly. For example, the first rotation-to-linear transmission structure includes a gear coaxially connected to the output shaft 52 and racks respectively arranged on the first track 41 and the second track 42, and the gear is meshed with both racks.

[0043] In addition, since the first driving mechanism 5 is connected between the second tracks 42 of the two first slide rail assemblies 1, the first driving mechanism 5 is always located below the seat body and does not occupy extra space inside the vehicle. Moreover, since the first driving mechanism 5 is composed of the rotary driving part 51 and two output shafts 52 located at both ends thereof, it is an elongated structure extending along the Y-axis (the left-right direction of the vehicle) and has a small dimension in the X-axis direction, so that more installation space can be reserved for other driving mechanisms (such as the second driving mechanism 6 mentioned later), making the layout more reasonable. In addition, using one first driving mechanism 5 can drive the second tracks 42 of the two first slide rail assemblies 1 to move, with a simple structure and small occupied space.

[0044] In some other embodiments, the first driving mechanism 5 can also be a linear driving mechanism to drive the second track 42 of the first slide rail assembly 1 to make a reciprocating linear motion relative to the first track 41.

[0045] As Figure 2 and Figure 4 shown, optionally, let one of the first slide rail assemblies 1 be a calibration slide rail assembly, and the distance between the rotary driving part 51 and the calibration slide rail assembly is greater than the distance between the rotary driving part 51 and the other first slide rail assembly 1.

[0046] Here, the first slide rail assembly 1 on the right side can be set as the calibration slide rail assembly. The distance between the rotary drive part 51 and the calibration slide rail assembly, that is, the first slide rail assembly 1 on the right side, is relatively large. That is, the rotary drive part 51 is arranged to be biased towards the first slide rail assembly 1 on the left side. There is a relatively large space on the right side of the rotary drive part 51, which is convenient for avoiding related components, such as the second drive mechanism 6 described below, so that the second drive mechanism 6 can smoothly move in the space on the right side of the rotary drive part 51. Of course, arranging the rotary drive part 51 to be biased towards the first slide rail assembly 1 on the left side can also avoid related structures on the vehicle floor. Since the distances between the rotary drive part 51 and the two first slide rail assemblies 1 are not equal, correspondingly, the lengths of the two output shafts 52 can be set to be inconsistent according to actual needs.

[0047] As Figures 2-4 shown, optionally, the seat adjustment device further includes a second drive mechanism 6. The second drive mechanism 6 is located between the two second slide rail assemblies 2. The second drive mechanism 6 is located on the side of the rotary drive part 51 close to the calibration slide rail assembly. The second drive mechanism 6 is used to drive the second track 42 of the second slide rail assembly 2 to move relative to the first track 41. The second drive mechanism 6 can only move in the space on the side of the rotary drive part 51 close to the calibration slide rail assembly. In this way, there can be enough Y-direction space between the rotary drive part 51 and the calibration slide rail assembly for the installation and movement of the second drive mechanism 6, and the lower surface of the second drive mechanism 6 can be arranged to be lower than the upper surface of the rotary drive part 51, reducing the overall space occupied by the first drive mechanism 5 and the second drive mechanism 6 in the Z direction, and thus saving the space occupied by the seat adjustment device in the vehicle Z direction. In order not to affect the first drive mechanism 5 to drive the first slide rail assembly 1, the lower surface of the second drive mechanism 6 can be arranged to be higher than the output shaft 52 here.

[0048] Optionally, the second drive mechanism 6 is located between the two second slide rail assemblies 2. There are two second drive mechanisms 6. The two second drive mechanisms 6 are arranged at intervals in the vehicle front-rear direction and are respectively drivingly connected to the corresponding second slide rail assemblies 2 close to them.

[0049] Here, the two second driving mechanisms 6 can both be rotary driving motors, which can provide a rotational driving force around the X-axis. Each second driving mechanism 6 can be connected to the second slide rail assembly 2 through a corresponding second rotational-to-linear transmission structure. The second rotational-to-linear transmission structure is arranged inside the second slide rail assembly 2 and is connected to the first track 41 and / or the second track 42 of the second slide rail assembly 2. The rotational driving force of the second driving mechanism 6 is converted into a linear driving force through the second rotational-to-linear transmission structure to drive the second track 42 of the second slide rail assembly 2 to move relative to the first track 41, driving the seat body to move in the left-right direction of the vehicle. Additionally, by using two second driving mechanisms 6 to respectively drive the second tracks 42 of the corresponding second slide rail assemblies 2 to move, the driving force for the left-right movement of the seat body can be increased. The two second driving mechanisms 6 are driven synchronously to ensure the driving effect. The second driving mechanisms 6 are located between the two second slide rail assemblies 2, that is, below the seat body, and do not occupy additional space inside the vehicle.

[0050] As Figures 1-2 shown, optionally, the seat adjustment device further includes a first mounting bracket 81. The two ends of the first mounting bracket 81 are respectively fixedly connected to the second tracks 42 of the two first slide rail assemblies 1. The rotary driving part 51 is mounted on the first mounting bracket 81. The two output shafts 52 respectively pass through the first mounting bracket 81 and are inserted between the first track 41 and the second track 42 of the corresponding first slide rail assembly 1.

[0051] Specifically, the first mounting bracket 81 extends along the direction shown by the Y-axis. The two ends of the first mounting bracket 81 can be respectively fixed to the second tracks 42 of the corresponding first slide rail assemblies 1 by bolts. The first mounting bracket 81 provides a supporting force for the first driving mechanism 5, enabling the first driving mechanism 5 to be stably mounted between the two first slide rail assemblies 1. The first driving mechanism 5 is fixed to the second track 42 of the first slide rail assembly 1 through the first mounting bracket 81 and can move relative to the first track 41 together with the second track 42, simplifying the connection between the first driving mechanism 5 and other structures of the vehicle body and ensuring the stability of seat adjustment.

[0052] Optionally, the seat adjustment device further includes a second mounting bracket 82. The second mounting brackets 82 are arranged in one-to-one correspondence with the second driving mechanisms 6. The second driving mechanisms 6 are mounted on the corresponding second mounting brackets 82, and the second mounting brackets 82 are fixedly connected to the second tracks 42 of the second slide rail assemblies 2.

[0053] Both the second driving mechanism 6 and the second mounting bracket 82 can be provided in two numbers. The two second mounting brackets 82 are respectively fixedly connected to the second rails 42 of the corresponding second slide rail assembly 2 to support the corresponding second driving mechanism 6, realizing the installation and fixation of the second driving mechanism 6, so that the second driving mechanism 6 can move together with the second rails 42 of the second slide rail assembly 2, which can simplify the connection between the second driving mechanism 6 and other structures of the vehicle body and ensure the stability of seat adjustment. When the second driving mechanism 6 adopts the same structure as the first driving mechanism 5, the installation is similar to that of the first driving mechanism 5 and will not be repeated here.

[0054] As Figure 1 , Figures 5-8 shown, optionally, the seat adjustment device further includes a third driving mechanism 7. The second turntable 32 is located above the first turntable 31. The third driving mechanism 7 is fixed above the second turntable 32 and is drivingly connected to the first turntable 31.

[0055] Here, the third driving mechanism 7 is arranged above the second turntable 32. Compared with being arranged between the first turntable 31 and the second turntable 32, it can save the Z - direction space occupation of the turntable assembly 3. The output end of the third driving mechanism 7 can be connected to the first turntable 31 through a transmission structure such as a gear - rack, etc. to drive the second turntable 32 to rotate relative to the first turntable 31. The second turntable 32 can be an annular turntable, and part of the transmission structure such as a gear - rack can be located in the internal space enclosed by the inner circle of the second turntable 32. Among them, two third driving mechanisms 7 can be provided to ensure sufficient rotational driving force.

[0056] The third driving mechanism 7 can be a rotary driving motor. The two third driving mechanisms 7 can respectively provide a rotational driving force around the Z - axis through a transmission structure such as a gear - rack, etc. to jointly drive the second turntable 32 to rotate relative to the first turntable 31 around the Z - axis, ensuring sufficient driving force for the horizontal rotation of the seat body.

[0057] As Figures 1-2 shown, optionally, the seat adjustment device further includes a first connecting bracket 91. The first rail 41 of the first slide rail assembly 1 is used to be fixedly connected to the vehicle floor through the first connecting bracket 91;

[0058] and / or, the seat adjustment device further includes a second connecting bracket 92. The first rail 41 of the second slide rail assembly 2 is fixedly connected to the second rail 42 of the first slide rail assembly 1 through the second connecting bracket 92.

[0059] Specifically, the first connecting bracket 91 can be a bent structure. One end of the first connecting bracket 91 is provided with a first bent section, which is arranged relatively parallel to the first track 41 of the first slide rail assembly 1. The first bent section is attached to and fixed to the first track 41 of the first slide rail assembly 1 by bolts. The other end of the first connecting bracket 91 is bent towards the direction close to the vehicle floor to be connected to the vehicle floor. First connecting brackets 91 can be respectively arranged at both ends of the first track 41 of the first slide rail assembly 1 to improve the installation stability of the first slide rail assembly 1 on the vehicle floor.

[0060] The second connecting bracket 92 is arranged below the first track 41 of the second slide rail assembly 2. It can be a long structure consistent with the extending direction of the first track 41 of the second slide rail assembly 2, or a block structure arranged at both ends of the first track 41 of the second slide rail assembly 2. The first track 41 of the second slide rail assembly 2 is fixedly connected to the second track 42 of the first slide rail assembly 1 through the second mounting bracket 82, and the second mounting bracket 82 is used to improve the connection strength between the first track 41 of the second slide rail assembly 2 and the second track 42 of the first slide rail assembly 1.

[0061] Another embodiment of the present utility model provides a vehicle seat, which includes a seat body and the above-mentioned seat adjusting device, and the second turntable 32 of the seat adjusting device is connected to the seat body. This vehicle seat can be a vehicle front-row seat or a rear-row seat.
