Detailed implementation manners

[0025] The following is a more detailed description of the specific implementation manners of the present utility model with reference to the accompanying drawings and through the description of embodiments, aiming to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate its implementation.

[0026] As Figure 1 and Figure 5-1 shown, the rear seat rotation installation and positioning structure includes a frame 1 and a vehicle body bracket 2. The frame 1 includes a mounting shaft 11. The mounting shaft 11 passes through the vehicle body bracket 2. A fixing block 4 is provided on the vehicle body bracket 2. A rotating block 3 is sleeved on the mounting shaft 11. A locking mechanism is provided on the rotating block 3. Both the fixing block 4 and the rotating block 3 are sleeved on the mounting shaft 11. The fixing block 4 is fixed to the vehicle body bracket 2. Through the locking function of the rotating block 3, when the pin shaft 32 is installed in place, that is, the frame 1, the rotating block 3 and the vehicle body bracket 2 remain stationary, the installation and positioning requirements of the seat frame 1 are completed.

[0027] As Figures 1 to 6-2 shown, a fixing hole 21 is provided on the vehicle body bracket 2. A chute 41 is provided on the fixing block 4. A through hole 42 is provided at the end of the chute 41. A platform 31 is provided on the rotating block 3. The locking mechanism includes a pin shaft 32. The pin shaft 32 is provided on the platform 31. The pin shaft 32 sequentially passes through the through hole 42 and the fixing hole 21. A spring 5 is sleeved on the mounting shaft 11. The spring 5 presses against the rotating block 3. The platform 31 provides an installation position for the pin shaft 32. When the spring 5 is compressed, it will apply an axial pressure to the rotating block 3. Since the fixing block 4 is clamped to the vehicle body bracket 2, when the rotating block 3 is rotated, the pin shaft 32 slides along the chute 41. When the pin shaft 32 passes through the through hole 42 and the fixing hole 21 due to the pressure of the spring 5, the pin shaft 32 is in the fixing hole 21 and cannot be disengaged, that is, the rotating block 3 and the frame 1 are restricted in the radial direction to form a reliable fixation. Combining the connection between the fixing block 4 and the vehicle body bracket 2 to restrict the frame 1 in the axial direction, a reliable installation and positioning effect of the frame 1 is achieved.

[0028] As Figure 3 and Figure 4As shown, a boss 33 is provided inside the rotating block 3. A groove structure is formed between the boss 33 and the rotating block 3. One end of the spring 5 is sleeved on the boss 33. An external hexagonal shaft 12 is provided on the mounting shaft 11. An internal hexagonal hole 34 is provided on the boss 33. The internal hexagonal hole 34 cooperates with the external hexagonal shaft 12. In the above structure, the setting of the boss 33 not only provides a setting position for the internal hexagonal hole 34, but also forms a sleeving space for the spring 5. The spring 5 is more stable in the radial direction and is not easily disengaged. After the internal hexagonal hole 34 cooperates with the external hexagonal shaft 12, the synchronous rotation of the rotating block 3 and the skeleton 1 is realized, facilitating the movement process of the pin shaft 32 along the sliding groove 41 during subsequent assembly. When the pin shaft 32 is installed in place, due to the cooperation of the internal hexagonal hole 34 and the external hexagonal shaft 12, the skeleton 1 will also be unable to rotate. And because the spring 5 is always in a compressed state, the skeleton 1 is in a locked state, and the skeleton 1 and the vehicle body bracket 2 will remain stable.

[0029] As Figure 6-1 and Figure 6-2 shown, the sliding groove 41 is arc-shaped, and both the sliding groove 41 and the pin shaft 32 are arranged at equal intervals in the circumferential direction. The arc-shaped sliding groove 41 is consistent with the rotation movement path of the pin shaft 32, reducing the sliding resistance of the pin shaft 32 and improving the smoothness of the assembly process. By setting a plurality of uniformly distributed pin shafts 32, the connection reliability between the skeleton 1 and the vehicle body bracket 2 can be improved.

[0030] As Figure 3 shown, one end of the rotating block 3 is provided with a sleeve 35, and a mounting hole 44 is provided in the middle of the fixed block 4. The sleeve 35 cooperates with the mounting hole 44. The sleeve 35 provides a mounting position for the preliminary mounting of the fixed block 4 and makes the skeleton 1 not directly contact the fixed block 4, avoiding the rotation of the skeleton 1 from affecting the stability of the fixed block 4.

[0031] As Figure 5-2 shown, an opening 22 is provided on the vehicle body bracket 2, and clamping grooves 43 are provided in the middle of both sides of the fixed block 4. The clamping grooves 43 cooperate with the opening 22. In the above structure, the installation of the fixed block 4 can be completed directly by inserting and clamping it from the opening 22, reducing the assembly difficulty. When the seat needs to be disassembled, it is only necessary to remove the fixed block 4 from the opening 22 and disassemble the fastening nut 13 to disassemble the skeleton 1.

[0032] As Figure 3 and Figure 4 shown, a fastening nut 13 and a gasket 14 are provided at the end of the mounting shaft 11, and the fastening nut 13 presses the fixed block 4. The fastening nut 13 prevents the rotating block 3 and the fixed block 4 from disengaging from the skeleton 1. Using the gasket 14 can avoid excessive extrusion deformation of the fixed block 4. By removing the fastening nut 13, the rotating block 3, the fixed block 4, and the spring 5 can be easily removed from the mounting shaft 11 in the axial direction.

[0033] As Figure 5-1 and Figure 5-2As shown, the vehicle body bracket 2 is of a U-shaped structure. The U-shaped vehicle body bracket 2 facilitates the clamping and fixing of the fixing block 4.

[0034] As Figure 6-2 shown, chamfers 6 are provided at both the end of the platform 31 and the fixing block 4. The platform 31 and the fixing block 4 have the same size, which is convenient for the operator to identify and align. The provision of the chamfers 6 can reduce the stress concentration at the corners of the above structure and also improve the aesthetics.

[0035] An automobile includes the above-mentioned rear seat rotation mounting and positioning structure.

[0036] The installation operation process is as follows: Assemble the spring 5, the rotating block 3 and the fixing block 4 onto the installation shaft 11, install the fastening bolts and fix them tightly. Place the pin shaft 32 into the chute 41 of the fixing block 4, and the inner hexagonal hole of the rotating block 3 is assembled onto the skeleton 1 of the outer hexagonal shaft 12 to ensure that the rotating block 3 rotates together with the skeleton 1 when the skeleton 1 rotates; after all the above components are assembled, install and clamp the fixing block 4 onto the vehicle body bracket 2, and the skeleton 1 drives the rotating block 3 to rotate and lock. When the pin shaft 32 rotates along the chute 41 to align with the through hole 42, under the action of the elastic force of the spring 5, the pin shaft 32 is squeezed into the through hole 42 and passes through the fixing hole 21, so as to achieve the function of fixing the pin shaft 32. At the same time, since the rotating block 3 and the skeleton 1 adopt a hexagonal shaft hole fit, the skeleton 1 cannot rotate, the spring 5 always presses the rotating block 3, and the pin shaft 32 cannot escape from the fixing hole 21, that is, the reliable installation and fixation of the skeleton 1 and the vehicle body bracket 2 are completed.

[0037] This rear seat rotation mounting and positioning structure uses the spring 5, the rotating block 3 and the fixing block 4 to realize the effective installation and positioning fixation between the skeleton 1 and the vehicle body bracket 2. Compared with the traditional technology, it reduces the use of bolts, reduces the assembly difficulty, improves the assembly efficiency, the structures of all components are simple, the installation is convenient, the connection is reliable and effective, and it can form a universal part of the platform 31 and can be adapted and applied to other vehicle bodies.

[0038] The above has made an exemplary description of the present invention in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above methods. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present invention; or without improvement, the above concept and technical solution of the present invention are directly applied to other occasions, they are all within the protection scope of the present invention.
