[0049] Example 1

[0050] Please refer to Figure 1-10B , Figure 1 This is a schematic structural diagram of an electric turntable for a car seat provided in an embodiment of the present invention; Figure 2 for Figure 1 A partial enlarged view of Figure 3 for Figure 1 Exploded view of; Figure 4 for Figure 3 A schematic diagram of the structure of the locking component; Figure 5 for Figure 1 , wherein the locking member is in the unlocked position; Figure 6 for Figure 1 , wherein the locking member is in a locked position; Figure 7 This is the installation structure diagram of the first driving component; Figure 8 for Figure 1 sectional view of Figure 9 for Figure 8 A partial enlarged view of the connection between the first plate, the outer edge pressure plate and the second plate; Figure 10A for Figure 8 A partial enlarged view of a connection structure of the first plate, the inner edge pressure plate and the second plate; Figure 10B for Figure 8 A partial enlarged view of another connection structure of the first disk body, the inner edge pressure plate and the second disk body.

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

[0052] The rotating disc assembly 1000 includes a first disc 1100 and a second disc 1200. The first disc 1100 and the second disc 1200 are arranged axially opposite each other, and the first disc 1100 is configured to rotate relative to the second disc 1200. During installation, one of the first disc 1100 and the second disc 1200 can be connected to the seat body, while the other can be connected to the vehicle floor or a slide rail assembly mounted on the vehicle floor.

[0053] Detailed description, such as Figure 3 As shown, the rotating disk assembly 1000 may further include a second drive component 1300. The second drive component 1300 may be mounted on the first disk body 1100. The second drive component 1300 may be provided with a drive gear 1310. The second disk body 1200 may be provided with a ring gear 1210. The drive gear 1310 and the ring gear 1210 may mesh with each other. Thus, the second drive component 1300 can drive the first disk body 1100 and the second disk body 1200 to rotate relative to each other. Specifically, the second drive 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 may be mounted on the first disk body 1100. The second driving component 1300 may be mounted and fixed via the first bracket 1600 and the second bracket 1700. In this manner, the second driving component 1300 may be connected and fixed via multiple different brackets, i.e., the second driving component 1300 may have a greater number of support connection points, thereby increasing the installation reliability of the second driving component 1300 and reducing the possibility of the second driving component 1300 shifting during use.

[0055] It should be understood that the above-mentioned implementation method of providing the first bracket 1600 and the second bracket 1700 for the second drive component 1300 is merely an exemplary description of the embodiment of the present invention in conjunction with the accompanying drawings, and it is not intended to limit the scope of implementation of the electric turntable for automobile seats provided by the present invention. Under the condition that the function is met, the second drive component 1300 can also be installed and fixed using other connection methods. For example, the second drive component 1300 can also be installed and fixed using only one bracket, which can be the first bracket 1600 or the second bracket 1700 described above. For another example, 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] The first driving component 2100 is mounted on the first tray body 1100 and includes a driving rod 2110. The driving rod 2110 is configured to be displaceable along its axial direction. The locking component 2200 is mounted on the second tray body 1200 and includes a locking slot 2210. The locking component 2300 includes a locking portion 2310. The driving rod 2110 is connected to the locking component 2300 and is used to drive the locking portion 2310 to engage or disengage with the locking slot 2210.

[0058] Combine Figure 5 When the locking portion 2310 and the locking groove 2210 are separated, the locking member 2300 may be in the unlocked position, and the first plate 1100 and the second plate 1200 can rotate relative to each other to adjust the circumferential position of the seat body. Figure 6 When the locking portion 2310 and the locking groove 2210 are plugged into each other, the locking component 2300 may be in a locked position, the first plate 1100 and the second plate 1200 cannot rotate relative to each other, and the circumferential position of the seat body cannot be adjusted.

[0059] During the above process, the position change of the locking portion 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 portion 2310 into the locking slot 2210, the impact force between the locking portion 2310 and the locking component 2200 is relatively controllable, with low noise, which can reduce the abnormal locking sound, thereby significantly improving the user experience. Moreover, when the locking portion 2310 is inserted into the locking slot 2210, the driving rod 2110 of the first driving component 2100 and the locking component 2300 remain connected. If the locking portion 2310 wants to disengage from the locking slot 2210, it must overcome the mechanical structure of the first driving component 2100, which is relatively difficult. In other words, the locking portion 2310 is not easily affected by external forces and disengaged from the locking slot 2210, which is conducive to improving the reliability of the locking, and thus the reliability of the seat body.

[0060] In fact, in some usage scenarios, the first driving component 2100 may also have a self-locking function. In this way, when the first driving component 2100 is not started, it will be more difficult for the locking portion 2310 to disengage from the locking slot 2210, and the locking reliability will be higher.

[0061] Here, the embodiments of the present invention do not limit the specific structural form of the first drive component 2100. In actual 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 drive component 2100 can be a power cylinder such as a pneumatic cylinder or an oil cylinder. In this case, the drive rod 2110 can be the piston rod of the power cylinder. For another example, the first drive component 2100 can also be a screw motor. In this case, the drive rod 2110 can be a screw that can be displaced along its axial direction.

[0062] The rotating disk assembly 1000 may also include a third bracket 1800, and the third bracket 1800 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. In this way, on the one hand, the first drive component 2100 may be connected and fixed via a plurality of different brackets, that is, the first drive component 2100 may have a greater number of connection support points, so that the installation reliability of the first drive component 2100 may be relatively high, and the possibility of the first drive component 2100 shaking during use may be reduced; on the other hand, the first drive component 2100 and the aforementioned second drive component 1300 may share the first bracket 1600 for installation, which may also reduce the number of brackets provided and improve the structural compactness and assembly efficiency of the electric turntable.

[0063] It should be understood that the above-mentioned method of installing and fixing the first drive component 2100 through the first bracket 1600 and the third bracket 1800 is merely an exemplary description of the embodiment of the present invention in conjunction with the accompanying drawings, and it cannot be used as a limitation on the scope of implementation of the electric turntable for automobile seats provided by the present invention. Under the condition that the functions are met, the first drive component 2100 can also be installed and fixed using other connection methods. For example, the first drive component 2100 can also be installed and fixed using only one bracket, which can be the above-mentioned first bracket 1600 or the third bracket 1800. For another example, the first drive component 2100 can also be installed and fixed using three or more brackets, which is also feasible.

[0064] In addition, the embodiment of the present invention does not limit the specific structural form of the locking component 2200. In practical applications, those skilled in the art can select it according to specific needs, as long as it can meet the requirements of use. Figure 5 and Figure 6 A locking component 2200 may be provided with only one locking groove 2210. In a specific implementation, a plurality of locking components 2200 may be provided, and the plurality of locking components 2200 may be spaced apart along the circumferential direction, so as to achieve locking of the seat body at different circumferential positions.

[0065] In some implementations, the locking member 2300 may be rotatably connected to the first disk 1100. In this case, the driving rod 2110 may be used to drive the locking member 2300 to rotate, and the locking portion 2310 may be configured to rotate into or out of the locking slot 2210.

[0066] like Figure 3 and Figure 4 As shown, the locking component 2300 may further include a locking frame 2320. The locking portion 2310 may be specifically rod-shaped and may be mounted on the locking frame 2320 so that the locking portion 2310 and the locking frame 2320 can operate synchronously. The locking frame 2320 may be rotatably connected to the first disk 1100 and may be combined with the first disk 1100 to form a locking member. Figure 5 and Figure 6The locking frame 2320 may be rotatably connected to the first disk body 1100 via the rotating shaft 2330. The driving rod 2110 may be connected to the locking portion 2310, or the driving rod 2110 may be connected to the locking frame 2320. In short, as long as the driving rod 2110 can generate a rotational driving force on the locking component 2300 to drive the locking component 2300 to rotate around the central axis of the rotating shaft 2330, it will be sufficient. Taking the connection between the driving rod 2110 and the locking portion 2310 as an example, it can be seen that the driving rod 2110 and the locking portion 2310 can rotate relative to each other, that is, the driving rod 2110 and the locking portion 2310 are rotatably connected, which can prevent the driving rod 2110 and the locking portion 2310 from getting stuck.

[0067] Combine Figure 2 The first plate body 1100 may be provided with a first guide hole 1110, and the locking portion 2310 may be slidably assembled in the first guide hole 1110. The first guide hole 1110 can provide sliding guidance for the locking portion 2310 to ensure the displacement direction of the locking portion 2310, so that the locking portion 2310 can accurately slide into or out of the locking slot 2210. In this embodiment of the present invention, considering that the locking component 2300 operates in the form of rotational displacement, the first guide hole 1110 can be configured as an arc-shaped hole to accommodate the arc-shaped rotation trajectory of the locking portion 2310.

[0068] In some implementations, such as Figure 7 As shown, the first driving component 2100 may further include a connecting frame 2120, and the first driving component 2100 may be rotatably connected to the first disk body 1100 via the connecting frame 2120. In this way, the first driving component 2100 may also rotate to a certain extent, which can largely avoid the locking component 2300 from getting stuck during the process of the first driving component 2100 driving the locking component 2300 to move, thereby improving 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 panels 2121 and a base panel 2122. The two side panels 2121 can be arranged opposite each other and both can be connected to the base panel 2122. One of the two side panels 2121 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 specifically be a screw or bolt. The connecting frame 2120 can rotate about the central axis of the two connectors 2130, which means that the first driving component 2100 can rotate about the central axis of the two connectors 2130.

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

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

[0072] The inner edge pressure plate 1400 can be located on the inner edge side of the first disk body 1100, and the outer edge pressure plate 1500 can be located on the outer edge side of the first disk body 1100. Both the inner edge pressure plate 1400 and the outer edge pressure plate 1500 can pressurize the first disk body 1100 and can be connected to the second disk body 1200, thereby reducing the possibility of separation of the rotating disk assembly 1000 during operation.

[0073] The rolling support component 3000 can be arranged between the outer edge pressure plate 1500 and the first disk body 1100, between the inner edge pressure plate 1400 and the first disk body 1100, and between the first disk body 1100 and the second disk body 1200. It can reduce the running resistance when the outer edge pressure plate 1500 and the first disk body 1100 rotate relative to each other, as well as the rotation resistance between the inner edge pressure plate 1400 and the first disk body 1100, and the rotation resistance between the first disk body 1100 and the second disk body 1200. It can improve the rotation smoothness between the inner edge pressure plate 1400 and the first disk body 1100, the rotation smoothness between the outer edge pressure plate 1500 and the first disk body 1100, and the rotation smoothness between the first disk body 1100 and the second disk body 1200, which is conducive to ensuring the smooth operation of the electric turntable provided by the embodiment of the present invention.

[0074] Here, the embodiment of the present invention does not limit the specific structural form of the above-mentioned rolling support component 3000. In actual application, those skilled in the art can make a choice according to specific needs, as long as it can meet the requirements of use. For example, the rolling support component 3000 can be annular, including an annular body and a plurality of balls mounted on the annular body, each ball being used to reduce the rotational resistance and improve the smoothness of rotation. For another example, the rolling support component 3000 can also include at least two split bodies, each of which can be arranged at intervals along the circumferential direction, and each of which can be provided with at least one ball. This is also feasible.

[0075] like Figure 9As shown, the outer edge pressure plate 1500 may include an outer edge pressure plate 1510. The above-mentioned rolling support component 3000 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, and the first flange 1520 is used to connect with the second plate body 1200; the outer edge of the first plate body 1100 may be provided with a second flange 1130, and the flange direction of the second flange 1130 is opposite to that of the first flange 1520 (see FIG. Figure 9 , the first flange 1520 is the lower flange, and the second flange 1130 is the upper flange), and the second flange 1130 can be located on the inner side of the first flange 1520. With this solution, the first flange 1520 can form a radial stop for the second flange 1130, and the outer edge pressure plate 1510 can form an axial stop for the second flange 1130, which can effectively complete the limited assembly of the first disk body 1100, thereby reducing the possibility of separation during operation of the electric turntable.

[0076] At least one of the first flange 1520 and the second flange 1130 can be configured as a complete ring. In this way, the outer edge pressure plate 1500 can better limit the first plate body 1100 and 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, and the above-mentioned rolling support component 3000 may be arranged between the inner edge pressure plate 1410 and the first disk body 1100, and the inner edge of the inner edge pressure plate 1410 may be provided with a third flange 1420, and the third flange 1420 is used to connect with the second disk body 1200.

[0078] The third flange 1420 may be located on the inner side of the first plate 1100. A clearance eliminating component 4000 may be disposed between the first plate 1100 and the third flange 1420 to eliminate radial clearance between the first plate 1100 and the third flange 1420. The clearance eliminating component 4000 may specifically be a bushing that can be directly sleeved onto the inner edge of the first plate 1100. The bushing may be a single-piece annular sleeve; alternatively, the bushing may include at least two separate sleeves, each of which may be spaced apart circumferentially.

[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 plate 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 arranged between the first plate body 1100 and the inner edge pressure plate 1400 can be an integrated structure to improve the integration and compactness of the structure.

[0080] In practical applications, the electric turntable provided by the embodiments of the present invention can be operated under the control of a control module such as an electronic control unit (ECU). The first drive component 2100 and the second drive component 1300 can both be equipped with Hall effects to record their respective rotational positions, and 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 disk body 1100 and the second disk body 1200 to rotate relative to each other, so that the locking portion 2310 can be aligned with the corresponding locking slot 2210. Then, the first drive component 2100 can be activated to drive the locking portion 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 structural diagram of another electric turntable for a car seat provided by an embodiment of the present invention, wherein the locking component is in the unlocked position; Figure 12 This is a schematic structural diagram of another electric turntable for a car seat provided by an embodiment of the present invention, wherein the locking component is located in a locking position.

[0083] An embodiment of the present invention further provides another electric turntable, the basic principle and basic structural arrangement of which are the same as those of the aforementioned embodiment 1. The following embodiment of the present invention mainly describes the differences between it and embodiment 1.

[0084] In this embodiment of the present invention, the locking member 2300 also adopts a rotating arrangement. The difference is that the locking portion 2310 can be a toothed plate with locking teeth 2311, and the locking member 2200 can be a corresponding gear ring. This allows for a greater number of locking slots 2210, allowing the first and second disc bodies 1100 and 1200 to be locked at more locations along the circumference, thus enhancing the adjustability of the electric turntable.

[0085] In an embodiment of the present invention, the locking component 2300 may not include the aforementioned locking frame 2320, and the locking portion 2310 may be directly rotatably connected to the first disk body 1100 via the rotating shaft 2330. The locking component 2300 may further include a connecting handle 2340, which may be connected to the locking portion 2310, and the driving rod 2110 may be connected to the connecting handle 2340 to drive the locking portion 2310 to rotate via the connecting handle 2340. It can be seen that the driving rod 2110 and the connecting handle 2340 are capable of relative rotation, that is, the driving rod 2110 and the connecting handle 2340 are rotatably connected, which can prevent the driving rod 2110 and the connecting handle 2340 from getting stuck.

[0086] In this embodiment of the present invention, the first plate 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 provide sliding guidance for the connecting handle 2340 to ensure the displacement direction of the locking portion 2310, so that the locking portion 2310 can accurately slide into or out of the locking slot 2210.

[0087] Example 3

[0088] Please refer to Figure 13-15 , Figure 13 This is a schematic structural diagram of another electric turntable for a car seat provided by an embodiment of the present invention; Figure 14 for Figure 13 , wherein the locking member is in the unlocked position; Figure 15 for Figure 13 , wherein the locking component is in the locked position.

[0089] The embodiment of the present invention further provides another electric turntable, the basic principle and structural arrangement of which are the same as those of the aforementioned embodiment 1. The following embodiment of the present invention mainly describes the differences between it and embodiment 1.

[0090] like Figure 13-15 As shown, in this embodiment of the present invention, the locking component 2300 can be slidably connected to the first disk body 1100 along a straight line. In this case, the locking component 2300 can only include a locking portion 2310, one end of which can be connected to the driving rod 2110, and the other end of the locking portion 2310 can be used to cooperate with the locking groove 2210 to lock or unlock the electric turntable.

[0091] In an embodiment of the present invention, the first plate body 1100 may be provided with a second guide hole 1120, and the locking portion 2310 may be disposed in the second guide hole 1120. The second guide hole 1120 can provide sliding guidance for the locking portion 2310 to ensure the displacement direction of the locking portion 2310, so that the locking portion 2310 can accurately slide into or out of the locking slot 2210. In an embodiment of the present invention, considering that the locking component 2300 moves in a linear manner, the first guide hole 1110 can be configured as a linear hole to accommodate the linear displacement trajectory of the locking portion 2310.

[0092] Example 4

[0093] Please refer to Figure 16-Figure 19 , Figure 16 This is a schematic structural diagram of another electric turntable for a car seat provided by an embodiment of the present invention; Figure 17 for Figure 16 A partial enlarged view of Figure 18 for Figure 16 , wherein the locking member is in the unlocked position; Figure 19 for Figure 16 A schematic structural diagram from another perspective, wherein the locking component is in the locked position.

[0094] The embodiment of the present invention further provides another electric turntable, the basic principle and structural arrangement of which are the same as those of the aforementioned embodiment 3. The following embodiment of the present invention mainly describes the differences between it and embodiment 3.

[0095] like Figure 16-19 As shown, in this embodiment of the present invention, the locking component 2300 may further include an adapter frame 2350 and a guide rod 2360. The adapter frame 2350 and the locking portion 2310 may be located on opposite axial sides of the first disk body 1100, respectively. 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 portion 2310. The first disk body 1100 may be provided with a second guide hole 1120, and the guide rod 2360 may be slidably assembled in the second guide hole 1120 to be slidably guided by the second guide hole 1120.

[0096] In the embodiment of the present invention, the adapter frame 2350 and the driving rod 2110 can be directly connected. Alternatively, the adapter frame 2350 and the driving rod 2110 can also be indirectly connected. This implementation method can be seen in Figure 17 The adapter frame 2350 may also be connected to a traction shaft 2370 , and the drive rod 2110 may be connected to the traction shaft 2370 , thereby enabling an indirect connection between the adapter frame 2350 and the drive rod 2110 .

[0097] In this embodiment of the present invention, the locking portion 2310 may also be a toothed plate, on which locking teeth 2311 may be provided. Accordingly, the locking component 2200 may be provided as a gear ring. Furthermore, the locking portion 2310 and the locking component 2200 may each adopt other structural forms, such as those described in the first and third embodiments, as long as they meet the requirements of use.

[0100] Since the aforementioned electric turntable already has the above technical effects, accordingly, the car seat with the electric turntable should also have similar technical effects, so it will not be elaborated here.

[0101] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
