Detailed Description

In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.

Without loss of generality, the seat turnplate shown in the drawings is used in the embodiment to explain the driving transmission principle in detail, and specific dimensional parameters of the driving part, the intermediate transmission part and the like do not substantially limit the technical scheme claimed in the application.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic view of an overall structure of a seat pan according to the present embodiment, and fig. 2 is an exploded view of the seat pan. The seat turnplate mainly comprises a rotating mechanism 100, a locking mechanism 200, a driving part (preferably a motor 300) and a transmission linkage mechanism 400, wherein the rotating mechanism 100 is provided with an annular upper turnplate 101 and an annular lower turnplate 103 which are matched in a rotating manner, after the assembly is completed, the upper turnplate 101 is connected with the bottom of a seat (not shown in the figure), and the lower turnplate 103 can be connected with a seat slide rail or directly connected with a vehicle body (not shown in the figure); for example, but not limited to, the upper rotary plate 101 is fixedly connected with the seat through an upper connecting bolt 102, and the lower rotary plate 103 is fixedly connected with the slide rail or the vehicle body through a lower connecting bolt 104.

The upper rotary table 101 can rotate relative to the lower rotary table 103 under the driving of the motor 300, and the working position of the upper rotary table 101 relative to the lower rotary table 103 is locked and unlocked through the locking mechanism 200; it should be understood that the "working position" refers to the relative position of the upper rotary plate 101 after the seat angle is set according to the requirement of the passenger, and the locking of the working position can ensure the safety of the passenger during the use process.

In this embodiment, the transmission linkage mechanism 400 is adopted to transmit the power provided by the motor 300 to the unlocking ends of the upper rotating disk 101 and the locking mechanism 200 respectively.

Wherein, the main transmission member 401 rotates coaxially with the output end of the motor 300. Specifically, the motor 300 may be fixed in different manners, for example, the motor may be fixed on the bracket 302 by screws 301, and the bracket 302 may be fixed on the lower rotating disk 103 by welding or other manners. The main transmission 401 can likewise be realized in a different manner, as shown in fig. 2, the main transmission 401 being connected to the electric motor 300 and to the carrier 302 via a spline shaft 303. After the motor 300 is started, the main transmission member 401 is driven to rotate by the patterned shaft 303. To ensure the smoothness of the main transmission member 401 during transmission, a bracket 304 is fixed on the upper side of the main transmission member 401. The bracket 304 is fixed to the bracket 302 by screws 305. Reference is also made to fig. 4, which shows the assembled relationship of the turndown disk and associated components.

The unlocking slave transmission piece 402 and the rotating slave transmission piece 403 which are in transmission fit with the master transmission piece 401 respectively transmit power to the unlocking ends of the upper rotating disc 101 and the locking mechanism 200, and the rotating slave transmission piece 403 is fixedly arranged on the upper rotating disc between the adjacent unlocking slave transmission pieces 402. Two unlocking slave transmission members 402 and one rotating slave transmission member 403 are provided as shown in the drawings, and the interlocking operation mechanism is described in detail in this preferred arrangement.

Referring also to fig. 3, fig. 3 shows the assembly of the upper rotary plate and the associated components. In the scheme, the unlocking slave transmission piece 402 can be switched between an unlocking working position and a locking working position in a sliding manner relative to the upper rotating disc 101, and the master transmission piece 401 and one of the two unlocking slave transmission pieces 402 in a locking state are adapted to the locking working position; fig. 1 shows a locking position in which the seat is held in a defined relative position with respect to the base rails or the vehicle body.

The pulling member 404 has a first end and two second ends linked with the first end, the first end is pulled to the unlocking end of the locking mechanism 200, and each second end is pulled to the corresponding unlocking driven transmission member 402; here, the pulling member 404 may be preferably implemented by a cable linked by a connector 4041, the first cable 4042 may be linked by the connector 4041 and two second cables 4043, respectively, a first end of the unlocking end of the locking mechanism 200 is formed at a free end of the first cable 4042, and a second end of the secondary transmission member 402 is formed at a free end of the second cable 4043.

On the basis, the unlocking slave transmission piece 402 has a preset stroke in sliding switching, and the preset stroke needs to meet the unlocking end displacement of the locking mechanism 200; that is, when the unlocking is switched from the locking operation position to the unlocking operation position by sliding the transmission member 402, the locking mechanism 200 may complete the unlocking based on the setting of the pulling member 404.

Meanwhile, when the unlocking slave transmission member 402 slides from the locking working position to the unlocking working position under the driving of the master transmission member 401, the master transmission member 401 may drive the rotating slave transmission member 403 on the downstream side of the unlocking slave transmission member 402 to rotate. It can be understood that, after the main transmission member 401 drives the locking mechanism 200 to complete unlocking, the upper rotating disc 101 is driven to adjust the angle of the seat, that is, a driving component is adopted to intermittently drive the unlocking and rotating member to realize automatic unlocking and rotating functions.

After the assembly is completed, the rotating disc is in a locked state under a normal state. When the seat needs to be automatically adjusted and rotated, the motor 300 is started, firstly, the unlocking auxiliary transmission piece 402 is driven by the main transmission piece 401 to slide relative to the upper rotating disc 101 and switch to the unlocking working position, the unlocking operation of the locking mechanism 200 is realized by the drawing part 404, and the upper rotating disc 101 is kept still in the unlocking process; after the unlocking stage is completed, the motor 300 continues to rotate to enter the rotation stage, and then the main transmission member 401 drives the rotary driven transmission member 403 and the upper rotary table 101 to rotate to the working position expected by the passenger, so as to complete the driving of the rotation stage.

In addition, based on the structural feature that transmission interlock mechanism 400 adopts tractive part 404 to realize with the locking mechanism interlock, this scheme still can adopt manual operation tractive part 404 to carry out the unblock operation simultaneously, and then rotates the seat to have concurrently and realize the rotation regulation function of seat through manual automatic unblock and drive.

In order to further optimize the structure, the primary transmission member 401 and the unlocking secondary transmission member 402 and the rotating secondary transmission member 403 are matched for tooth meshing transmission, so that the inner space of the rotary table can be effectively utilized, and the advantage of reliable transmission is achieved. As shown, the main transmission member 401 is a gear rotating coaxially with the output shaft of the motor 300, and the unlocking slave transmission member 402 and the rotating slave transmission member 403 are respectively and correspondingly configured to be arc-shaped meshing tooth segments according to the functional angle requirement. Circumferentially, one end of the unlocking slave transmission piece 402 is located above the upper rotating disk 101 and the other end is located on the upper surface of the rotating slave transmission piece 403, whereby further, the mating pair of the sliding switching is formed between the unlocking slave transmission piece 402 and the rotating slave transmission piece 403 and the upper surface of the upper rotating disk 101. So set up, but furthest utilizes circumference and radial assembly space, and product structural arrangement is compacter reasonable.

Of course, it is also possible to adopt a design in which a mating pair (not shown in the drawings) forming the sliding switch between the unlocking slave transmission member 402 and one of the rotating slave transmission member 403 and the upper rotating disk 101 also achieves the above-described fitting function.

Preferably, the sliding switching engagement pair is configured as: an arc-shaped groove 4021 which is concentric with an indexing circle of the meshing teeth is formed in the unlocking driven transmission piece 402, guide posts 4022 matched with the corresponding arc-shaped grooves 4021 are arranged on the upper surfaces of the rotating driven transmission piece 403 and the upper rotating disc 101, a preset stroke is ensured through the arc length design of the arc-shaped grooves 4021, and good displacement tracks are ensured in the unlocking and resetting locking processes of the unlocking driven transmission piece 402. Here, the arc grooves 4021 are at least two, and the at least two arc grooves 4021 are staggered in the radial direction, so that the deflection possibly generated in the transmission process can be further avoided, and the displacement trajectory is ensured.

In fact, it is also possible to provide the arc-shaped slot and the guiding post in opposite directions, and the upper surface of the rotary driven member and/or the upper rotary table may be provided with an arc-shaped slot arranged concentrically with the reference circle of the meshing teeth thereon, and accordingly, the guiding post is arranged on the unlocking driven member (not shown in the figures), it being understood that the functional requirements of obtaining a good displacement trajectory are all within the scope of the present application.

To improve carousel performance, further optimization may be made for unlocking slave drive piece 402 and rotating slave drive piece 403. As shown in connection with fig. 3, unlocking slave transmission member 402 is located adjacent to rotary slave transmission member 403, and the downstream side of unlocking slave transmission member 402 from unlocking mesh teeth 4023 has rotary synchronizing mesh teeth 4024, which rotary synchronizing mesh teeth 4024 axially overlap with upstream end mesh teeth 4031 of rotary slave transmission member 403 to synchronize the rotation of upper rotary disk 101. The terms of orientation of "upstream" and "downstream" as used herein are defined with reference to the order of transmission adaptation of the respective components to the main transmission 401, and are used only for clarity of illustration of the dynamic cooperation relationship between the components, and do not constitute a limitation to the substance of the present disclosure.

With the arrangement, the driven transmission member 401 continues to rotate after the unlocking in the unlocking stage is completed, so that the unlocking end of the locking mechanism 20 continues to be driven to move, and the good reset posture of the locking mechanism is ensured to be kept; in addition, the rotating synchronous meshing teeth 4024 and the upstream end meshing teeth 4031 of the rotating driven transmission member 403 synchronously drive the upper rotating disc 101 to rotate, so that the high bearing capacity is achieved at the initial moment of seat rotation, and the rotation adjusting function of the seat is ensured to be smoothly achieved.

It should be noted that the locking mechanism 200 for locking and unlocking the operating position of the upper rotating disk 101 with respect to the lower rotating disk 103 may be implemented in different structures according to the needs, which are adapted to the pulling member 404. Such as but not limited to the preferred form shown in the drawings.

Please also refer to fig. 5, which is a sectional view a-a of fig. 1.

As shown in fig. 1 to 3 and fig. 5, the locking mechanism 200 mainly includes an unlocking piece 201, a locking pin 202 and a lock bracket 203, wherein the unlocking piece 201 is pivoted with the upper rotating disc 101 through a pivoting shaft 204, and an unlocking end adapted to a first end of the pulling member 404 is located on the unlocking piece 201; one end of the locking pin 202 is fixedly connected with the unlocking piece 201 beside the pivoting shaft 204, and the other end of the locking pin passes through a through hole 1011 formed in the upper rotating disc 101 and is clamped and matched with the locking groove 2031; the lock bracket 203 provided with the locking groove 2031 is fixedly provided on the lower rotating disk 103. The engagement and adaptation between the locking pin 202 and the locking groove 2031 are specifically configured as follows: the first end of the pulling member 404 pulls the unlocking piece 201 to drive the locking pin 202 to be unlocked and separated from the locking groove 2031, and the locking mechanism 200 can be pulled by the first pulling rope 4042 to unlock the upper and lower rotary tables.

It is determined that the open side of the locking groove 2031 should also meet the disengagement space requirements of the locking pin 202. In addition, the through hole 1011 of the upper rotating disk 101 is an arc-shaped through hole concentrically disposed with the pivot shaft 204, and the stroke of the locking pin 202 in the arc-shaped through hole 1011 is greater than or equal to the stroke of the locking pin 201 unlocking and disengaging from the locking groove 2031.

In addition, the locking mechanism 200 shown in the figure further includes a return torsion spring 205 sleeved on the pivot shaft 204 to have a locking return function. Two force application ends of the reset torsion spring 205 are respectively connected with the unlocking sheet 201 and the upper rotating disc 101, preferably pre-deformed, so as to keep a locking state; the elastic deformation energy is stored in the process that the unlocking sheet 201 drives the locking pin 202 to unlock and disengage. Thus, when primary driver 401 is disengaged from unlocking secondary driver 402, return torsion spring 205 pulls unlocking tab 201 and locking pin 202 back to the locked position, while simultaneously pulling the corresponding unlocking secondary driver 402 by second cable 4043 to slide switch to the locked position.

Further, a reinforcing disc 105 can be arranged between the upper rotating disc 101 and the lower rotating disc 103, and particularly, the reinforcing disc 105 is fixedly connected with the upper rotating disc 101 to enclose an annular closed cavity, so that the structural strength is enhanced. Correspondingly, the reinforcing plate 105 is provided with a through hole 1051 axially opposite to the through hole 1011 of the upper rotating plate 101 so that the locking pin 202 can pass through.

Meanwhile, a pressure plate 106 is arranged, the upper rotary plate 101 assembled with the reinforcing plate 105 is concentrically arranged in the lower rotary plate 103, and the pressure plate 105 is fixedly connected to the lower rotary plate 103. The upper end of the pressure plate 106 is provided with a limiting ring 1061 which extends outwards in the radial direction, the lower end of the pressure plate 106 penetrates through the middle parts of the upper rotating disc 101 and the reinforcing disc 105 to be fixedly connected with the lower rotating disc 103, and axial limiting is formed on the upper surface of the upper rotating disc 101 through the limiting ring 1061. Thus, the platen 105 has a function of preventing the falling-off in addition to a function of pressing the upper and lower rotating disks.

The platen 105 is fixedly connected to the lower rotary table 103, and may be regarded as a whole. For convenience of description, the reinforcing plate 105 and the upper rotating plate 101 are referred to as a "rotor", and the whole formed by the lower rotating plate 103 and the pressure plate 106 is referred to as a "stator", without reference to the moving state of the upper and lower rotating plates. Because there is relative rotation between the "rotor" and the "stator", it is necessary to improve the smooth and smooth performance of the rotational movement between the two.

First, the "rotor" and the "stator" have two contact positions in the vertical direction, i.e., the pressure plate 106 is in contact with the upper rotating disk 101, the reinforcing disk 105 is in contact with the lower rotating disk 103, and sliding elements may be added at these two positions. Here, the sliding element may be assembled with the fixed cage by a series of steel balls, rollers or other rolling elements, forming a whole; but also plastic or other metal parts with lubricating coatings on the surfaces. The scheme preferably adopts metal sheets with surfaces coated with special materials, namely upper and lower friction sheets (107, 108), wherein the upper friction sheet 107 is arranged between the limiting ring 1061 of the pressure plate 106 and the upper rotating disc 101, and the lower friction sheet 108 is arranged between the outer peripheral edge of the reinforcing disc 105 and the lower rotating disc 103.

In addition, the contact between the "rotor" and the "stator" is also present in the horizontal direction, and therefore, a friction ring 109, preferably a plastic friction washer, may be provided between the wall of the central hole of the upper rotating disk 101 and the outer circumferential surface of the pressure plate 106, thereby reducing the product cost while achieving good friction performance.

In addition, upper and lower anti-slip members may be provided. As shown in the attached drawings, at least two upper anti-slip parts 110 are fixedly arranged on the periphery of the upper rotating disc 101 at intervals, and the plate body of each upper anti-slip part 110 extends downwards and then is bent to form an upper hook part upwards; at least two lower anti-falling parts 111 are fixedly arranged on the periphery of the lower rotating disc 103 at intervals, and the plate body of each lower anti-falling part 111 extends upwards and then is bent downwards to form a lower hook part; each upper anti-falling part 110 and each lower anti-falling part 111 are axially arranged oppositely, and the upper hook part and the lower hook part can be inserted in the circumferential direction to form an axial limiting pair. The cooperation of the anti-disengaging hook makes the carousel can not take place the condition that breaks away from top to bottom when moving or jolting.
