[0043] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0044] The following is for reference. Figures 1-13 The seat rotation mechanism 100 according to an embodiment of the present utility model can effectively offset the changing gap between the transmission component 21 and the drive mechanism 32 during the rotation of the moving plate 2, thereby ensuring that the rotation of the moving plate 2 is more stable and smooth.

[0045] Combination Figures 1-13 As shown, the seat rotation mechanism 100 according to the first aspect of the present invention includes a fixed plate 1, a moving plate 2, a reinforcing bracket 7, and a first elastic member 8.

[0046] Specifically, the fixed plate 1 is used to connect to the seat base 200, and the movable plate 2 is used to connect to the seat body 300. The movable plate 2 is rotatably mounted on the fixed plate 1 and is equipped with a transmission component 21. One end of the reinforcing bracket 7 is connected to the movable plate 2, and the other end of the reinforcing bracket 7 is located below the fixed plate 1. A first elastic element 8 is connected to the other end of the reinforcing bracket 7, and at least a portion of the first elastic element 8 abuts against the lower surface of the fixed plate 1 to compensate for the vertical gap of the movable plate 2 during rotation. For example, the first elastic element 8 is a rubber component, which facilitates the integral injection molding of the rubber component onto the reinforcing bracket 7, improving manufacturing efficiency and overall structural consistency.

[0047] The upper end of the reinforcing bracket 7 is connected to the moving plate 2, and the reinforcing bracket 7 rotates synchronously with the moving plate 2. The lower end of the reinforcing bracket 7 is connected to the first elastic element 8, and at least part of the first elastic element 8 forms an abutment relationship with the lower surface of the fixed plate 1. This helps the first elastic element 8 to absorb (that is, to buffer and suppress the impact caused by the shaking of the moving plate 2 through its own deformation) the vertical shaking gap (that is, the vertical impact force) of the moving plate 2 during the rotation process, thereby ensuring the vertical stability of the moving plate 2.

[0048] Therefore, by setting up the seat rotation mechanism 100, the first elastic element 8 can absorb the vertical sway gap of the moving plate 2 during the rotation process, thereby ensuring the vertical stability of the moving plate 2 and improving the passenger's user experience.

[0049] According to some optional embodiments of the present invention, combined with Figure 2 and Figure 12As shown, the first elastic element 8 is constructed in an arch shape that is higher in the middle and lower on both sides along its length. This allows the material to be concentrated in the middle of the first elastic element 8, which helps to improve the local structural strength of the middle part. Moreover, it makes the first elastic element 8 and the lower surface of the fixed plate 1 form a smaller contact area. Under the premise of ensuring normal contact between the two (that is, when the moving plate 2 forms a wobbling displacement in the vertical direction, the first elastic element 8 can absorb the vertical gap of the moving plate 2 in time), it can also reduce the friction between the first elastic element 8 and the fixed plate 1, which helps to improve the smoothness of the rotation of the fixed plate 1.

[0050] In addition, the first elastic element 8 is designed as an arched structure, which can keep the elastic slider in contact with the fixed plate 1 during the operation of the moving plate 2, eliminate the vertical gap of the moving plate 2 during the rotation process, and make the moving plate 2 more stable during operation.

[0051] Alternatively, combined Figure 2 and Figure 12 As shown, the reinforcing bracket 7 includes a top plate 71, a side plate 72, and a bottom plate 73. The top plate 71 is located above the moving plate 2 and extends radially away from the center of the moving plate 2. The side plate 72 is bent and connected to the top plate 71 and extends towards the thickness direction of the moving plate 2. The side plate 72 is located on the outer periphery of the moving plate 2. The bottom plate 73 is bent and connected to the side plate 72 and extends radially towards the center of the moving plate 2. The bottom plate 73 is located below the fixed plate 1. An upwardly extending flange 74 is provided at one end of the bottom plate 73 near the center of the moving plate 2. The flange 74 extends into the groove 12 in the outer periphery direction of the fixed plate 1. A first elastic member 8 is provided on the flange 74.

[0052] The top plate 71 corresponds to the upper surface of the moving disk 2. The side plate 72 changes the structural extension direction of the top plate 71, and the bottom plate 73 changes the extension direction of the side plate 72. This can form a shape that matches the circumferential contour of the moving disk 2 and provide structural protection and reinforcement for the moving disk 2 in the circumferential direction. The flange 74 changes the structural extension direction of the bottom plate 73 again, which makes it easier to shorten the distance between the first elastic element 8 on the flange 74 and the lower surface of the moving disk 2, thereby improving its practicality. The flange 74 extends into the groove 12, and the first elastic element 8 on the flange 74 is also located in the groove 12, which helps to improve the structural protection of the first elastic element 8.

[0053] Alternatively, combine Figures 2-4As shown, there are multiple reinforcing brackets 7 and multiple first elastic elements 8. The reinforcing brackets 7 are spaced apart along the circumference of the moving disk 2, and each reinforcing bracket 7 corresponds to a first elastic element 8. This arrangement can create multiple structural reinforcements on the moving disk 2 in the circumferential direction, thereby improving the structural strength of the moving disk 2. It also allows for an increase in the number and position of the first elastic elements 8 in the circumferential direction of the moving disk 2, thus more evenly absorbing the vertical swaying gaps on the outer periphery of the moving disk 2, further improving the rotational stability of the moving disk 2. For example, one first elastic element 8 can be arranged on the reinforcing bracket 7, or multiple first elastic elements 8 can be arranged, and the arrangement is not limited to this.

[0054] Furthermore, the reinforcing bracket 7 can be used to meet the strength test of the three-point seat belt anchor point, which helps to eliminate operational clearance and ensure the operational stability of the moving plate 2. The fixed plate 1 connects to the lower frame (slide rail) of the seat mechanism, and as the carrier of the fixed part, it can also be used to meet the strength test of the three-point seat belt anchor point. In summary, after meeting the strength test of the three-point seat belt anchor point, since the seat belt can rotate the seat during driving, it can still provide sufficient protection for passengers. Thus, the seat rotation mechanism 100 can meet the needs of both parking and driving. For example, when the seat rotation mechanism 100 is subjected to external load, the reinforcing bracket 7 and the fixed plate 1 will interlock and lock together, bearing a certain external load and ensuring the strength performance of the seat rotation mechanism 100.

[0055] According to some optional embodiments of the present invention, combined with Figure 2 , Figure 6 and Figure 8 As shown, the seat rotation mechanism 100 also includes a drive assembly 3 and a second elastic member 4. The drive assembly 3 includes a mounting bracket 31 and a drive mechanism 32. The mounting bracket 31 is connected to the fixed plate 1. The drive mechanism 32 is disposed on the mounting bracket 31 and is connected to the transmission member 21 to drive the moving plate 2 to rotate. The second elastic member 4 is disposed between the fixed plate 1 and the mounting bracket 31 to counteract the radial clearance between the transmission member 21 and the drive mechanism 32 during the rotation of the moving plate 2.

[0056] Specifically, the fixed plate 1 is fixedly connected to the seat base 200, and the movable plate 2 is connected to the seat body 300. The movable plate 2 can rotate relative to the fixed plate 1, which facilitates the movable plate 2 to drive the seat body 300 to rotate synchronously. The movable plate 2 is fixedly connected to the mounting bracket 31, and the drive mechanism 32 is mounted on the mounting bracket 31. The transmission component 21 of the movable plate 2 is mutually connected to the drive mechanism 32. The drive mechanism 32 transmits the driving force to the transmission component 21, and the transmission component 21 drives the movable plate 2 to rotate. Since the transmission component 21 and the drive mechanism 32 are mutually transmitted during the rotation of the movable plate 2, which can easily form a transmission gap, the second elastic component 4 in this case is connected to the fixed plate 1 and the mounting bracket 31. When the movable plate 2 rotates, the second elastic component 4 can absorb the force transmitted from the transmission component 21 to the drive mechanism 32 and the mounting bracket 31 in sequence, and offset the transmission gap between the transmission component 21 and the drive mechanism 32 in the rotation direction, thereby ensuring smooth transmission between the two and improving the rotational stability and reliability of the movable plate 2. Therefore, by setting the seat rotation mechanism 100, it can effectively offset the changing gap between the transmission component 21 and the drive mechanism 32 during the rotation of the moving plate 2, thereby ensuring that the rotation of the moving plate 2 is more stable and smooth.

[0057] According to some optional embodiments of the present invention, combined with Figure 2 , Figure 3 , Figure 10 and Figure 13 As shown, the mounting bracket 31 is provided with a first limiting part 312, the fixed plate 1 is provided with a second limiting part 11, and the second elastic member 4 is radially interference-fitted between the first limiting part 312 and the second limiting part 11.

[0058] As arranged as described above, the first limiting part 312 and the second limiting part 11 can limit the second elastic member 4 in the radial direction of the fixed plate 1, preventing the risk of the second elastic member 4 shifting in the radial direction of the fixed plate 1. Due to the interference fit, the second elastic member 4 can also generate elastic pressure on both the first limiting part 312 and the second limiting part 11. Thus, when the second elastic member 4 is subjected to a radial force from the first limiting part 312 of the mounting bracket 31, the second elastic member 4 can undergo corresponding elastic deformation to generate a reaction force, thereby offsetting the transmission gap between the transmission member 21 and the drive mechanism 32 caused by the rotational inertia of the automatic plate 2.

[0059] According to some optional embodiments of the present invention, combined with Figure 2 and Figure 9As shown, the transmission component 21 is constructed as an arc-shaped internal rack; the drive mechanism 32 includes a drive component 321 and a transmission mechanism 322. The drive component 321 is mounted on the mounting bracket 31. The input end of the transmission mechanism 322 is connected to the drive component 321, and the output end of the transmission mechanism 322 is constructed as a gear that meshes with the rack. For example, the drive component 321 can be a motor, but it is not limited to this.

[0060] Furthermore, the gear meshes with the inner side of the internal rack, which has multiple teeth evenly distributed on its inner side and extends in an arc shape. Thus, when the gear is driven to rotate, the gear meshes with the internal rack, and the gear transmits the driving force and torque to the internal rack. The gear drives the internal rack to rotate, thereby driving the moving disk 2 to rotate synchronously.

[0061] Furthermore, the transmission form of the above embodiment is an internal rack and pinion drive (also known as rack and pinion internal gear), which can effectively increase the pitch circle diameter of the rack and reduce the amount of clearance caused by the clearance of the drive component 321 (such as a motor) to the entire structure.

[0062] Furthermore, the mounting bracket 31 is provided with an opening 311, and a first limiting part 312 is provided on one side of the opening 311 along the radial direction of the fixed plate 1. The fixed plate 1 is provided with a second limiting part 11, which passes through the opening 311 and is located on the other side of the opening 311 along the radial direction of the fixed plate 1. This is more conducive to the second elastic member 4 directly forming a limiting engagement relationship with the mounting bracket 31 and the fixed plate 1 in the radial direction.

[0063] According to some optional embodiments of the present invention, combined with Figure 2 , Figure 3 , Figure 10 and Figure 13 As shown, the mounting bracket 31 includes a main body 313 and a connecting part 314. In the radial direction of the fixed plate 1, the main body 313 corresponds to the middle part of the fixed plate 1, and the connecting part 314 is connected to both ends of the main body 313. Moreover, the connecting part 314 is located below the fixed plate 1, and the main body 313 protrudes vertically upward from the fixed plate 1. The seat rotation mechanism 100 also includes a third elastic member 5, which is arranged vertically and is disposed at the connection between the fixed plate 1 and the connecting part 314.

[0064] In this design, the moving plate 2 and the fixed plate 1 are hollow in the radial direction of the fixed plate 1, which is beneficial for lightweight design. The main body 313 protrudes vertically upward into the hollow space of the fixed plate 1, which can prevent mistakes and improve assembly efficiency. The connecting part 314 of the mounting bracket 31 corresponds to the lower part of the solid structure of the fixed plate 1. The third elastic member 5 is vertically arranged at the connection between the fixed plate 1 and the connecting part 314, which further absorbs the radial clearance of the mounting bracket 31, reduces the sway clearance of the drive mechanism 32, and improves the transmission smoothness of the transmission member 21 and the drive mechanism 32.

[0065] Specifically, in combination Figure 2 , Figure 8 , Figure 10 As shown, the seat rotation mechanism 100 also includes a fastener 6 and a first bushing 61. The fixed plate 1 is provided with a first mounting hole, the fastener 6 passes through the first mounting hole, and the first bushing 61 is fitted onto the fastener 6 and abuts against one side of the fixed plate 1. A third elastic member 5 is fitted onto the first bushing 61, and the connecting portion 314 is provided with a second mounting hole. The third elastic member 5 passes through the second mounting hole and is connected to the connecting portion 314. For example, the first bushing 61 can be a metal bushing, which facilitates the fixation of the third elastic member 5.

[0066] It is understandable that the fastener 6 passes through the first mounting hole of the setting plate 1 and the second mounting hole of the connecting part 314 in a vertical direction to fix the setting plate 1 and the mounting bracket 31 into a whole. The first bushing 61 is set between the fastener 6 and the third elastic member 5. This can prevent the third elastic member 5 from directly contacting the fastener 6, which helps to reduce the wear on the third elastic member 5 and thus improve the service life of the third elastic member 5.

[0067] In addition, the seat rotation mechanism 100 also includes a cap bracket 92, which is mainly used to fix the second elastic element 4.

[0068] Optionally, combined Figure 2 and Figure 11 As shown, the seat rotation mechanism 100 also includes a sliding assembly 81, which includes a retainer 811 and a plurality of rolling elements 812. The retainer 811 is disposed between the moving plate 2 and the fixed plate 1, and the plurality of rolling elements 812 are arranged at intervals along the circumference of the retainer 811. The rolling elements 812 are rotatably connected between the moving plate 2 and the fixed plate 1.

[0069] The retainer 811 maintains the relative position of the rolling element 812 with itself in the circumferential direction, preventing the rolling element 812 from falling off the retainer 811. At the same time, it does not restrict the rolling element 812 from rolling around its own center, and can also absorb vertical gaps and eliminate noise. The rolling element 812 is rotatably connected between the moving plate 2 and the fixed plate 1. This allows the moving plate 2 to provide force support to the fixed plate 1 through the rolling element 812, and also allows the moving plate 2 and the fixed plate 1 to form point contact with the rolling element 812 respectively. This reduces the contact area, which helps to reduce the friction force when the moving plate 2 rotates and eliminate abnormal noise. Thus, it simultaneously ensures the stability of the support of the fixed plate 1 to the moving plate 2 and the smoothness of the rotation of the moving plate 2, thereby improving the practicality of the seat rotation mechanism 100.

[0070] For example, the rolling element 812 is arranged in a circle of steel balls on the cage 811, which can effectively support the moving disk 2 and the fixed disk 1, so that the sliding trajectory of the entire moving disk 2 is in line-plane contact; during the rotation of the moving disk 2, the contact form between the moving disk 2 and the steel balls is rolling friction, which can reduce the friction force and eliminate the vertical gap generated by the moving disk 2 during the rotation.

[0071] For example, a slide is provided on the inner side of the fixed plate 1 along its circumference, which can be used to provide the running trajectory of the rolling element 812.

[0072] Alternatively, combine Figure 2 and Figure 6 As shown, the fixed plate 1 includes an inner ring body 13 and an outer ring body 14. The movable plate 2 is rotatably disposed on the inner ring body 13. The inner ring body 13 includes a connecting end 131 and a guiding end 132. The outer and inner peripheral edges of the guiding end 132 are both connected to the connecting end 131. The guiding end 132 extends radially downward. The outer ring body 14 surrounds the inner ring body 13 and is connected to the connecting end 131.

[0073] In this configuration, both the inner ring 13 and the outer ring 14 are hollow along the radial direction of the fixed plate 1. The inner and outer peripheral edges of the guide end 132 are connected to the connecting ends 131 on both sides, respectively. The guide section extends downward at an angle near the center of the fixed plate 1. The moving plate 2 is correspondingly constructed with a shape that matches the extension direction of the guide section. This allows the inner ring 13 to generate a component force in both the vertical and radial directions to support the moving plate 2, thereby ensuring the rotational stability of the moving plate 2. Furthermore, the outer ring 14 surrounds the inner ring 13, which helps to provide support for the inner ring 13 in both the circumferential and vertical directions, improving the structural reliability of the fixed plate 1.

[0074] Furthermore, compared to combining the traditional split clamp structure into one, the outer ring 14 of the fixed plate 1 in this case acts as a clamp, ensuring the strength of the seat rotation mechanism 100% at any rotation angle of the seat. Moreover, since the fixed plate 1 in this case is equivalent to a full-circle clamp structure, the upper end of the reinforcing bracket 7, which matches the outer periphery of the fixed plate 1, is provided with an elongated hole along the radial direction of the moving plate 2. This facilitates the bolts on the moving plate 2 to pass through the elongated hole on the side of the reinforcing bracket 7 near the center of the moving plate 2 before inserting the flange 74 of the reinforcing bracket 7 into the groove 12 of the fixed plate 1. Then, the reinforcing bracket 7 is moved radially along the moving plate 2 towards the center of the moving plate 2 to the side of the moving plate 2 where the bolts are near the elongated hole and away from the center of the moving plate 2. This smoothly achieves the assembly between the reinforcing bracket 7 and the moving plate 2 and the fixed plate 1, improving the assembly rationality of the reinforcing bracket 7.

[0075] Optionally, combined Figures 2-4 As shown, the seat rotation mechanism 100 also includes a moving plate fastening bracket 9, which is connected between the reinforcing bracket 7 and the seat body 300. It is mainly used to ensure the amount of clearance between the reinforcing bracket 7 and the moving plate 2 in the radial direction, thereby ensuring the stability of the clearance. The seat rotation mechanism 100 also includes a plastic-coated bracket 91, which covers part of the outer peripheral surface of the drive mechanism 32. It is mainly used to connect and fix the drive mechanism 32 to the fixed plate 1 after the drive mechanism 32 is engaged with the transmission component 21, thereby improving the positional stability of the drive mechanism 32.

[0076] Combination Figures 1-2 As shown, the seat according to the second aspect of the present invention includes a seat base 200, a seat body 300 and a seat rotation mechanism 100 as described above. The seat body 300 is located above the seat base 200. The fixed plate 1 is connected to the seat base 200 and the movable plate 2 is connected to the seat body 300.

[0077] The seat base 200 is connected to the vehicle body, and the fixed plate 1 of the seat rotation mechanism 100 is fixedly connected to the seat base 200, so that the seat rotation mechanism 100 can be firmly installed on the vehicle body; the moving plate 2 of the seat rotation mechanism 100 is fixedly connected to the seat body 300. Since the moving plate 2 can rotate relative to the fixed plate 1, the moving plate 2 can drive the seat body 300 to rotate, thereby meeting the user's need to rotate the seat.

[0078] For example, combining Figures 1-4As shown, the fixed plate 1 is connected to the seat base 200 of the car via projection weld bolts. The moving plate 2, the reinforcing bracket 7, and the moving plate fastening bracket 9 are connected to the car seat body 300 via projection weld bolts. The fixed plate 1 is connected to the moving plate 2 via the reinforcing bracket 7. The sliding assembly 81, as a plastic assembly, is assembled between the moving plate 2 and the fixed plate 1. The moving plate 2 can rotate on the sliding assembly 81, reducing surface friction, absorbing gaps, and eliminating abnormal noise. The drive mechanism 32 drives the rack on the moving plate 2 to rotate, thereby realizing the rotation function of the seat rotation mechanism 100.

[0079] Combination Figure 2 and Figure 5 As shown, the reinforcing bracket 7 and the fixed plate 1 serve as strength-ensuring components and are interlocked. During normal use, the fixed plate 1 is fixed to the car seat base 200, and the reinforcing bracket 7 rotates vertically around the fixed plate 1. The first elastic element 8 has an arch-shaped design and a partial interference fit with the fixed plate 1. As the movement clearance changes, it provides vertical elastic support for the moving plate 2, eliminating vertical clearance and maintaining constant line-surface contact between the moving plate 2 and the fixed plate 1, thus supporting the stability of the moving plate 2 during movement. Figure 2 , Figure 6 and Figure 8 As shown, when the seat rotation mechanism 100 is subjected to an external load, the reinforcing bracket 7 and the fixed plate 1 engage and lock together to withstand a certain external load, thus ensuring the strength performance of the turntable. The third elastic element 5 is pressed with a nut into the projection weld bolt (i.e., fastener 6) and the metal first bushing 61 (i.e., first bushing 61), and the third elastic element 5 is in elastic contact with the mounting bracket 31. The second elastic element 4 is pressed and fixed with a nut and cap bracket 92. The second elastic element 4 is interference-fitted between the fixed plate 1 and the mounting bracket 31, and is in elastic contact to absorb clearance in the reverse direction. During use, the drive mechanism 32 drives the internal rack to rotate the plate 2, and the mounting bracket 31 rotates vertically. The drive mechanism 32 meshes with the internal rack, which is a clearance fit. The second elastic element 4 is used to absorb the tooth meshing tolerance and ensure smooth transmission. The second bushing 62 can be a plastic bushing, which is connected between the plastic-coated bracket 91 and the transmission mechanism 322. It is mainly used to eliminate the abnormal noise generated by the friction between the shaft of the transmission mechanism 322 and the plastic-coated bracket 91 when it is driven by the motor.

[0080] The vehicle according to the third aspect of the present invention includes the seat of the above embodiment. The vehicle having the seat can effectively improve the rotational smoothness of the seat rotation mechanism 100 during the rotation process, improve riding comfort, eliminate safety hazards, thereby improving user experience and enhancing the overall vehicle market competitiveness.
