Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, specifically to an automotive seat and an electric turntable used in automotive seats. Background Technology

[0002] With the development of the times and the progress of society, the functions of car seats have gradually diversified, and more and more car seats are beginning to be equipped with a rotating function. In related technologies, car seats with rotating functions include electric turntables, which are used to achieve the rotation of the car seat. However, electric turntables in related technologies have the drawback of relatively high noise when locked.

[0003] Therefore, how to provide a solution to overcome or alleviate the above-mentioned defects remains a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a car seat and an electric turntable for use in the car seat, wherein the electric turntable has relatively low locking noise and relatively high locking reliability.

[0005] To solve the above-mentioned technical problems, this utility model provides an electric turntable for automobile seats, comprising: a rotating disc assembly including a first disc body, a second disc body, and a second driving component, wherein the second driving component is mounted on the first disc body and is used to drive the second disc body to rotate relative to the first disc body; a locking mechanism including a first driving component, a locking component, and a locking component; the first driving component is mounted on the first disc body and has a driving rod configured to be displaceable along its axial direction; the locking component is mounted on the second disc body and has a locking groove; the locking component includes a locking part, and the driving rod and the locking component are connected to drive the locking part to engage or disengage with the locking groove.

[0006] In this embodiment of the utility model, the electric turntable is equipped with a locking mechanism. The locking mechanism includes a first driving component, and the driving rod of the first driving component is connected to the locking part, which is used to drive the locking part to insert into the locking groove or to disengage from the locking groove, thereby enabling the locking and unlocking of the electric turntable.

[0007] During this process, the positional changes of the locking part are all driven by the first drive component. The driving force generated by the first drive component is relatively stable. When driving the locking part into the lock slot, the impact force between the locking part and the locking component is relatively controllable, resulting in less noise and reducing abnormal locking noise, thus significantly improving the user experience. Furthermore, when the locking part is inserted into the lock slot, the drive rod of the first drive component and the locking component remain connected. If the locking part wants to disengage from the lock slot, it needs to overcome the mechanical structure within the first drive component, which is relatively difficult. This means that the locking part is not easily disengaged from the lock slot by external forces, which helps improve the reliability of locking and, consequently, the reliability of the seat body.

[0008] Optionally, the locking component is rotatably connected to the first disc body, the drive rod is used to drive the locking component to rotate, and the locking part is configured to be able to rotate into or out of the locking groove.

[0010] Optionally, the locking part is a toothed plate with locking teeth, and the locking part is rotatably connected to the first disc body; the locking component further includes a connecting handle, which is connected to the locking part, and the driving rod is connected to the connecting handle. The first disc body is provided with a first guide hole, and the connecting handle is slidably fitted into the first guide hole.

[0011] Optionally, the first drive component further includes a connecting frame, through which the first drive component is rotatably connected to the first disc body.

[0012] Optionally, the locking component is slidably connected to the first disc body in a straight line.

[0013] Optionally, the locking component further includes an adapter and a guide rod. The adapter and the locking part are located on opposite axial sides of the first disc body. The adapter is connected to the drive rod, and the guide rod connects the adapter and the locking part. The first disc body is provided with a second guide hole, and the guide rod is slidably fitted into the second guide hole.

[0014] Optionally, the rotating disk assembly further includes an inner edge pressure plate and an outer edge pressure plate, and the electric turntable further includes a rolling support component. The inner edge pressure plate is located on the inner edge side of the first disk body, and the outer edge pressure plate is located on the outer edge side of the first disk body. The rolling support component is provided between the outer edge pressure plate and the first disk body, between the inner edge pressure plate and the first disk body, and between the first disk body and the second disk body.

[0015] Optionally, the outer edge of the outer pressure plate is provided with a first flange, the outer edge of the first disc body is provided with a second flange, the second flange is located inside the first flange, and at least one of the first flange and the second flange is annular; and / or, the inner edge of the inner pressure plate is provided with a third flange, the third flange is located inside the first disc body, and a gap-eliminating component is provided between the first disc body and the third flange; the rolling support component between the inner pressure plate and the first disc body and the gap-eliminating component are integral structures, or the rolling support component between the inner pressure plate and the first disc body and the gap-eliminating component are separate structures.

[0017] Since the aforementioned electric turntable already possesses the technical effects described above, the car seat equipped with the electric turntable should also possess similar technical effects, so it will not be elaborated upon here. Attached Figure Description

[0050] Please refer to Figures 1-10B , Figure 1 This is a schematic diagram of the structure of an electric turntable applied to an automobile seat provided in an embodiment of the present invention; Figure 2 for Figure 1 A magnified view of a portion of the image; Figure 3 for Figure 1 Exploded view; Figure 4 for Figure 3 Schematic diagram of the central locking component; Figure 5 for Figure 1 A bottom view, in which the locking component is in the unlocked position; Figure 6 for Figure 1 A bottom view, in which the locking component is in the locked position; Figure 7 This is a diagram showing the installation structure of the first drive component; Figure 8 for Figure 1 A sectional view; Figure 9 for Figure 8 A partial enlarged view of the connection between the first disc body, the outer edge pressure plate, and the second disc body; Figure 10A for Figure 8 A partially enlarged view of a connection structure between the first disc body, the inner edge pressure plate, and the second disc body; Figure 10B for Figure 8 A partially enlarged view of another connection structure between the first disc body, the inner edge pressure plate, and the second disc body.

[0051] like Figures 1-3 As shown, this embodiment of the invention provides an electric turntable for use in automobile seats, which can be used to rotate the seat body in an automobile seat to improve the functionality of the car seat. The electric turntable includes a rotating disk assembly 1000 and a locking mechanism 2000.

[0052] The rotating disk assembly 1000 includes a first disk body 1100 and a second disk body 1200, which are arranged opposite to each other along the axial direction of the rotating disk assembly 1000. The first disk body 1100 is configured to rotate relative to the second disk body 1200. In specific installation, one of the first disk body 1100 and the second disk body 1200 can be connected to the seat body, and the other can be connected to the vehicle floor or a slide rail assembly mounted on the vehicle floor.

[0053] Detailed explanation, such as Figure 3 As shown, the rotating disk assembly 1000 may further include a second driving component 1300, which can be mounted on the first disk body 1100. The second driving component 1300 may be equipped with a driving gear 1310; the second disk body 1200 may be equipped with a gear ring 1210; the driving gear 1310 and the gear ring 1210 can mesh with each other. Thus, under the action of the second driving component 1300, the first disk body 1100 and the second disk body 1200 can be driven to rotate relative to each other. Specifically, the second driving component 1300 may be a motor, etc.

[0054] The rotating disk assembly 1000 may further include a first bracket 1600 and a second bracket 1700, both of which can be mounted on the first disk body 1100. The second drive component 1300 can be mounted and fixed via the first bracket 1600 and the second bracket 1700. Thus, the second drive component 1300 can be connected and fixed via multiple different brackets, meaning the second drive component 1300 can have a greater number of support connection points, resulting in relatively high installation reliability and reducing the possibility of positional wobbling during use.

[0055] It should be understood that the above-described implementation of the first bracket 1600 and the second bracket 1700 for the second drive component 1300 is merely an exemplary description of the present invention in conjunction with the accompanying drawings. It should not be construed as limiting the scope of the electric turntable for automotive seats provided by the present invention. Under the condition of satisfying the function, the second drive component 1300 can also be installed and fixed using other connection methods. For example, the second drive component 1300 can be installed and fixed using only one bracket, which can be either the first bracket 1600 or the second bracket 1700 described above. Alternatively, the second drive component 1300 can also be installed and fixed using three or more brackets, which is also feasible.

[0056] The locking mechanism 2000 includes a first driving component 2100, a locking component 2200, and a locking component 2300.

[0057] A first driving component 2100 is mounted on a first disc body 1100. The first driving component 2100 has a driving rod 2110, which is configured to be displaceable along its axial direction. A locking component 2200 is mounted on a second disc body 1200 and has a locking groove 2210. A locking component 2300 includes a locking part 2310. The driving rod 2110 is connected to the locking component 2300 and is used to drive the locking part 2310 and the locking groove 2210 to engage or disengage.

[0058] Combination Figure 5 When the locking part 2310 and the locking groove 2210 are separated, the locking member 2300 can be in the unlocked position, and the first disc 1100 and the second disc 1200 can rotate relative to each other to adjust the circumferential position of the seat body. Figure 6 When the locking part 2310 and the locking groove 2210 are inserted, the locking part 2300 can be in the locked position, the first disc 1100 and the second disc 1200 cannot rotate relative to each other, and the circumferential position of the seat body cannot be adjusted.

[0059] In the above process, the position change of the locking part 2310 is driven by the first driving component 2100. The driving force generated by the first driving component 2100 is relatively stable. When driving the locking part 2310 into the lock groove 2210, the impact force between the locking part 2310 and the locking component 2200 is relatively controllable, with less noise, which can reduce abnormal locking noise and thus significantly improve the user experience. Furthermore, when the locking part 2310 is inserted into the lock groove 2210, the driving rod 2110 of the first driving component 2100 and the locking component 2300 still maintain a connection. If the locking part 2310 wants to disengage from the lock groove 2210, it needs to overcome the mechanical structure inside the first driving component 2100, which is relatively difficult. That is, the locking part 2310 is not easily disengaged from the lock groove 2210 by external forces, which helps to improve the reliability of locking and thus improves the reliability of the seat body.

[0060] In fact, in some usage scenarios, the first drive component 2100 can also have a self-locking function. In this way, when the first drive component 2100 is not activated, it will be more difficult for the locking part 2310 to disengage from the locking groove 2210, and the reliability of locking will be higher.

[0061] Here, this embodiment of the present invention does not limit the specific structural form of the first driving component 2100. In practical applications, those skilled in the art can select according to specific needs, as long as it can meet the requirements of use. For example, the first driving component 2100 can be a power cylinder such as a pneumatic cylinder or a hydraulic cylinder, in which case the driving rod 2110 can be the piston rod of the power cylinder. As another example, the first driving component 2100 can also be a lead screw motor, in which case the driving rod 2110 can be a lead screw, which can be displaced along its axial direction.

[0062] The rotating disk assembly 1000 may further include a third bracket 1800, which may also be mounted on the first disk body 1100. The first drive component 2100 may be mounted and fixed via the third bracket 1800 and the aforementioned first bracket 1600. Thus, on the one hand, the first drive component 2100 can be connected and fixed via multiple different brackets, meaning the first drive component 2100 can have a greater number of connection support points, resulting in relatively high installation reliability and reducing the possibility of positional wobbling during use; on the other hand, the first drive component 2100 and the aforementioned second drive component 1300 can share the first bracket 1600 for mounting, further reducing the number of brackets required and improving the structural compactness and assembly efficiency of the electric turntable.

[0063] It should be understood that the above-described method of mounting and fixing the first drive component 2100 via the first bracket 1600 and the third bracket 1800 is merely an illustrative example of the present invention in conjunction with the accompanying drawings. It should not be construed as limiting the scope of the electric turntable for automotive seats provided by the present invention. Under the condition of satisfying the function, the first drive component 2100 can also be mounted and fixed using other connection methods. For example, the first drive component 2100 can also be mounted and fixed using only one bracket, which can be either the first bracket 1600 or the third bracket 1800 described above. Furthermore, the first drive component 2100 can also be mounted and fixed using three or more brackets, which is also feasible.

[0064] Furthermore, this embodiment of the invention does not limit the specific structural form of the locking component 2200. In practical applications, those skilled in the art can select the appropriate form according to specific needs, as long as it meets the requirements of use. For example, see [reference needed]. Figure 5 and Figure 6 A locking component 2200 may have only one locking groove 2210. In specific implementation, multiple locking components 2200 may be provided, and the multiple locking components 2200 may be spaced apart along the circumference, thereby enabling the seat body to be locked at different positions in the circumference.

[0065] In some implementations, the locking member 2300 may be rotatably connected to the first disc body 1100. In this case, the drive rod 2110 may be used to drive the locking member 2300 to rotate, and the locking part 2310 is configured to rotate into or out of the lock groove 2210 in a rotatable manner.

[0066] like Figure 3 and Figure 4 As shown, the locking component 2300 may further include a locking frame 2320. The locking part 2310 may specifically be rod-shaped and can be mounted on the locking frame 2320, allowing the locking part 2310 and the locking frame 2320 to operate synchronously. The locking frame 2320 is rotatably connected to the first disc body 1100, in conjunction with... Figure 5 and Figure 6The locking frame 2320 can be rotatably connected to the first disc 1100 via a rotating shaft 2330. The drive rod 2110 can be connected to the locking part 2310, or the drive rod 2110 can be connected to the locking frame 2320; in short, as long as the drive rod 2110 can generate a rotational driving force on the locking part 2300 to drive the locking part 2300 to rotate around the central axis of the rotating shaft 2330, it is acceptable. Taking the connection between the drive rod 2110 and the locking part 2310 as an example, it can be seen that the drive rod 2110 and the locking part 2310 can rotate relative to each other, that is, the drive rod 2110 and the locking part 2310 are rotatably connected, which can prevent jamming between the drive rod 2110 and the locking part 2310.

[0067] Combination Figure 2 The first disc body 1100 may be provided with a first guide hole 1110, and the locking part 2310 may be slidably assembled in the first guide hole 1110. The first guide hole 1110 can slide and guide the locking part 2310 to ensure the displacement direction of the locking part 2310, so that the locking part 2310 can accurately slide into or out of the locking groove 2210. In this embodiment of the present invention, considering that the action mode of the locking component 2300 is rotational displacement, the first guide hole 1110 can be set as an arc-shaped hole to accommodate the arc-shaped rotation trajectory of the locking part 2310.

[0068] In some implementations, such as Figure 7 As shown, the first driving component 2100 may further include a connecting frame 2120, through which the first driving component 2100 can be rotatably connected to the first disc body 1100. In this way, the first driving component 2100 can also rotate to a certain extent, which can largely avoid jamming during the process of the first driving component 2100 driving the locking component 2300 to move, and can improve the smoothness of driving the locking component 2300.

[0069] Specifically, it can be combined with Figure 3 The connecting frame 2120 can be roughly U-shaped, including two side plate portions 2121 and one base plate portion 2122. The two side plate portions 2121 can be arranged opposite to each other, and both side plate portions 2121 can be connected to the base plate portion 2122. Of the two side plate portions 2121, one can be connected to the first bracket 1600 via a connector 2130, and the other can be connected to the third bracket 1800 via a connector 2130. The connector 2130 can be a screw or bolt, etc. The connecting frame 2120 can rotate around the central axis of the two connectors 2130, that is, the first driving component 2100 can rotate around the central axis of the two connectors 2130.

[0070] It should be understood that in some other implementations of this utility model, the first driving component 2100 may not include the connecting frame 2120 described above. In this case, the first driving component 2100 may be rotatably connected to the first disc body 1100 through other parts.

[0071] In some implementations, such as Figure 3 , Figures 8-10B As shown, the rotating disk assembly 1000 may also include an inner edge pressure plate 1400 and an outer edge pressure plate 1500, and the electric rotating disk may also include a rolling support component 3000.

[0072] The inner edge pressure plate 1400 can be located on the inner edge side of the first disc body 1100, and the outer edge pressure plate 1500 can be located on the outer edge side of the first disc body 1100. Both the inner edge pressure plate 1400 and the outer edge pressure plate 1500 can press against the first disc body 1100, and both the inner edge pressure plate 1400 and the outer edge pressure plate 1500 can be connected to the second disc body 1200, which can reduce the possibility of separation of the rotating disc assembly 1000 during operation.

[0073] The rolling support component 3000 can be disposed between the outer edge pressure plate 1500 and the first disc 1100, between the inner edge pressure plate 1400 and the first disc 1100, and between the first disc 1100 and the second disc 1200. It can reduce the running resistance when the outer edge pressure plate 1500 and the first disc 1100 rotate relative to each other, as well as the rotational resistance between the inner edge pressure plate 1400 and the first disc 1100, and between the first disc 1100 and the second disc 1200. It can improve the rotational smoothness between the inner edge pressure plate 1400 and the first disc 1100, as well as the rotational smoothness between the outer edge pressure plate 1500 and the first disc 1100, and between the first disc 1100 and the second disc 1200, which is beneficial to ensuring the smooth operation of the electric turntable provided in this utility model embodiment.

[0074] Here, this utility model embodiment does not limit the specific structural form of the rolling support component 3000 described above. In practical applications, those skilled in the art can select according to specific needs, as long as it can meet the requirements of use. For example, the rolling support component 3000 can be ring-shaped, including a ring-shaped body and a plurality of balls mounted on the ring-shaped body, each ball being used to reduce rotational resistance and improve the smoothness of rotation. Alternatively, the rolling support component 3000 can also include at least two separate parts, each part being arranged at intervals along the circumference, and each part being provided with at least one ball, which is also feasible.

[0075] like Figure 9As shown, the outer edge pressure plate 1500 may include an outer edge pressure plate 1510. A rolling support member 3000, as described above, may be provided between the outer edge pressure plate 1510 and the first plate body 1100. The outer edge of the outer edge pressure plate 1510 may be provided with a first flange 1520, which is used to connect to the second plate body 1200. The outer edge of the first plate body 1100 may be provided with a second flange 1130, the flange direction of which is opposite to that of the first flange 1520 (see...). Figure 9 The first flange 1520 is a lower flange, and the second flange 1130 is an upper flange, with the second flange 1130 located inside the first flange 1520. With this design, the first flange 1520 forms a radial stop on the second flange 1130, and the outer edge pressure plate 1510 forms an axial stop on the second flange 1130. This effectively limits the assembly of the first disc body 1100, thereby reducing the possibility of separation during the operation of the electric turntable.

[0076] Of the first flange 1520 and the second flange 1130 mentioned above, at least one can be set to be a complete ring. In this way, the outer edge pressure plate 1500 can better limit the first disc body 1100, and can better prevent the electric turntable from separating.

[0077] like Figure 10A As shown, the inner edge pressure plate 1400 may include an inner edge pressure plate 1410. The aforementioned rolling support component 3000 may be provided between the inner edge pressure plate 1410 and the first plate body 1100. The inner edge of the inner edge pressure plate 1410 may be provided with a third flange 1420, which is used to connect with the second plate body 1200.

[0078] The third flange 1420 may be located inside the first disc 1100. A gap-eliminating component 4000 may be provided between the first disc 1100 and the third flange 1420 to eliminate the radial gap between them. Specifically, the gap-eliminating component 4000 may be a bushing, which may be directly fitted onto the inner edge of the first disc 1100. The bushing may be an integral annular sleeve; alternatively, the bushing may include at least two sub-sleeves, which may be arranged circumferentially at intervals.

[0079] In some implementations, such as Figure 10A As shown, the rolling support component 3000 and the gap-eliminating component 4000 disposed between the first disc body 1100 and the inner edge pressure plate 1400 can be two separate components. In other implementations, such as Figure 10BAs shown, the rolling support component 3000 and the gap-eliminating component 4000 disposed between the first disc body 1100 and the inner edge pressure plate 1400 can be an integral structure to improve integration and structural compactness.

[0080] In practical applications, the electric turntable provided in this embodiment can operate under the control of a control module such as an Electronic Control Unit (ECU). Both the first drive component 2100 and the second drive component 1300 can have Hall effect sensors to record their respective rotational positions. The control module can record the position of the locking slot 2210. Under the control of the control module, the second drive component 1300 can drive the first disc body 1100 and the second disc body 1200 to rotate relative to each other, so that the locking part 2310 is aligned with the corresponding locking slot 2210. Then, the first drive component 2100 can be activated to drive the locking part 2310 into the corresponding locking slot 2210.

[0081] Example 2

[0082] Please refer to Figure 11 and Figure 12 , Figure 11 This is a schematic diagram of another electric turntable for use in a car seat, provided as an embodiment of the present invention, wherein the locking component is in the unlocked position; Figure 12 This is a schematic diagram of another electric turntable for use in a car seat, provided as an embodiment of the present invention, wherein the locking component is located in the locked position.

[0083] This utility model embodiment also provides another electric turntable, whose basic principle and basic structural settings are the same as those of the aforementioned embodiment one. The following description of this utility model embodiment mainly focuses on the differences between it and embodiment one.

[0084] In this embodiment of the invention, the locking component 2300 also adopts a rotating configuration. The difference is that the locking part 2310 can be a toothed plate, and the locking part 2310 can have locking teeth 2311. Correspondingly, the locking component 2200 can be a toothed ring. This allows for a greater number of locking grooves 2210, enabling the first disc 1100 and the second disc 1200 to lock at more positions in the circumferential direction, thus enhancing the adjustability of the electric turntable.

[0085] In this embodiment of the invention, the locking component 2300 may not include the aforementioned locking frame 2320, and the locking part 2310 may be directly rotatably connected to the first disc 1100 via the rotating shaft 2330. The locking component 2300 may also include a connecting handle 2340, which may be connected to the locking part 2310. The driving rod 2110 may be connected to the connecting handle 2340 to drive the locking part 2310 to rotate. It is understood that the driving rod 2110 and the connecting handle 2340 can rotate relative to each other, i.e., they are rotatably connected, thus preventing jamming between them.

[0086] In this embodiment of the invention, the first disc body 1100 may also be provided with a first guide hole 1110, and the connecting handle 2340 may be slidably assembled in the first guide hole 1110. The first guide hole 1110 can slide and guide the connecting handle 2340 to ensure the displacement direction of the locking part 2310, so that the locking part 2310 can accurately slide into or out of the locking groove 2210.

[0087] Example 3

[0088] Please refer to Figures 13-15 , Figure 13 A schematic diagram of another electric turntable applied to a car seat provided by an embodiment of the present utility model; Figure 14 for Figure 13 A bottom view, in which the locking component is in the unlocked position; Figure 15 for Figure 13 The bottom view shows the locking component in the locked position.

[0089] This utility model embodiment also provides another electric turntable, whose basic principle and structural setting are the same as those of the aforementioned embodiment one. The following description of this utility model embodiment mainly focuses on the differences between it and embodiment one.

[0090] like Figures 13-15 As shown, in this embodiment of the present invention, the locking component 2300 can be slidably connected to the first disc body 1100 in a straight direction. In this case, the locking component 2300 may only include a locking part 2310, one end of which can be connected to the drive rod 2110, and the other end of which can be used to cooperate with the lock groove 2210 to realize the locking or unlocking of the electric turntable.

[0091] In this embodiment of the invention, the first disc 1100 may be provided with a second guide hole 1120, and the locking part 2310 may be disposed in the second guide hole 1120. The second guide hole 1120 can slide and guide the locking part 2310 to ensure the displacement direction of the locking part 2310, so that the locking part 2310 can accurately slide into or out of the locking groove 2210. In this embodiment of the invention, considering that the action mode of the locking component 2300 is linear displacement, the first guide hole 1110 can be set as a linear hole to accommodate the linear displacement trajectory of the locking part 2310.

[0092] Example 4

[0093] Please refer to Figures 16-19 , Figure 16 This is a schematic diagram of another electric turntable applied to a car seat, provided by an embodiment of the present utility model; Figure 17 for Figure 16 A magnified view of a portion of the image; Figure 18 for Figure 16 A bottom view, in which the locking component is in the unlocked position; Figure 19 for Figure 16 A structural diagram from another perspective, in which the locking component is in the locked position.

[0094] This utility model embodiment also provides another electric turntable, whose basic principle and structural configuration are the same as those of the aforementioned embodiment three. The following description of this utility model embodiment mainly focuses on the differences between it and embodiment three.

[0095] like Figures 16-19 As shown in this embodiment of the invention, the locking component 2300 may further include an adapter frame 2350 and a guide rod 2360. The adapter frame 2350 and the locking part 2310 may be located on opposite axial sides of the first disc 1100. The adapter frame 2350 may be connected to the drive rod 2110, and the guide rod 2360 may connect the adapter frame 2350 and the locking part 2310. The first disc 1100 may be provided with a second guide hole 1120, and the guide rod 2360 may be slidably fitted into the second guide hole 1120 for sliding guidance through the second guide hole 1120.

[0096] In this embodiment of the invention, the adapter frame 2350 and the drive rod 2110 can be directly connected. Alternatively, the adapter frame 2350 and the drive rod 2110 can also be indirectly connected; this implementation can be found in [reference needed]. Figure 17 The adapter frame 2350 can also be connected to a traction shaft 2370, and the drive rod 2110 can be connected to the traction shaft 2370, thereby realizing an indirect connection between the adapter frame 2350 and the drive rod 2110.

[0097] In this embodiment of the invention, the locking part 2310 can also be a toothed plate, on which locking teeth 2311 can be provided, and correspondingly, the locking component 2200 can be a toothed ring. Alternatively, the locking part 2310 and the locking component 2200 can also adopt other structural forms, such as the structural forms in the aforementioned Embodiment 1 and Embodiment 3, as long as they meet the requirements of use.

[0098] Example 5

[0099] This utility model embodiment also provides an automobile seat, including a seat body and an electric turntable. The electric turntable is any of the electric turntables involved in the aforementioned embodiments one to four. In this electric turntable, one of the first disc body 1100 and the second disc body 1200 can be connected to the seat body, while the other of the first disc body 1100 and the second disc body 1200 can be connected to the vehicle floor or to a slide rail assembly mounted on the vehicle floor.

[0100] Since the aforementioned electric turntable already possesses the above-mentioned technical effects, correspondingly, the car seat with the electric turntable should also possess similar technical effects, so it will not be elaborated here.

[0101] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
