[0001] The utility model belongs to the technical field of automobile assembly, in particular to a fixing device for a backrest lock bracket of an automobile back plate. Background Art

[0002] At present, the automobile industry is developing rapidly and the competition is extremely fierce. The development of modern urban transportation has created convenience, but it has also increased certain safety hazards. Traffic safety is not only related to the life safety of passengers, but also to the construction of a harmonious society. When the car is driving, the seat belt is the first measure to ensure the safety of the people in the car, which can effectively ensure the safety of the passengers and the driver in the car. Among them, the safety performance of the car is particularly important. An important point in car safety is the installation of seat back locks, because this directly involves the life safety of the driver.

[0003] At present, most of the fixing processes of the car seat back lock bracket adopt manual mechanical installation. However, the car seat back lock bracket has many welds and large deformation. It is difficult to ensure the correct installation of the car seat belt after welding. At the same time, before use and installation, it is necessary to confirm the integrity of the car seat back lock bracket and whether the dimensions meet the requirements. At present, the method of simply relying on manual inspection before operation is inefficient. During installation, due to the large overall frame of the seat, it is inconvenient for personnel to operate and the efficiency is relatively low. Utility Model Content

The upper end of each rib plate 3 is fixedly connected to the corresponding upper base plate 4, and each upper end of the upper base plate 4 is provided with a slide rail 5. A connecting plate 2 6 is horizontally provided above each of the slide rails 5, and each connecting plate 2 6 is fixedly connected to the corresponding upper base plate 4. The two slide rails 5 and the two connecting plates 2 6 are slidably connected to the propulsion mechanism, and one end of one of the upper base plates 4 is hinged to the hand push pliers 1.

[0023] The propulsion mechanism includes a cylinder 7, a pin 8, a connecting plate 9 and a positioning plate 10;

[0024] The cylinder 7 is arranged between the two rib plates 3 and fixed on the base plate 2. The cylinder 7 is fixedly connected to the connecting plate 9 through a pin shaft 8. The connecting plate 9 is fixedly connected to the positioning plate 10. The lower end of the positioning plate 10 is slidably connected to the two slide rails 5 and the two connecting plates 6. The side wall of the positioning plate 10 is slidably connected to the long hole of the hand pliers 1. A plurality of threaded holes are provided at the upper end of the positioning plate 10. The positioning plate 10 is fixedly connected to the locking mechanism through bolts.

[0025] The locking mechanism includes an adjustment block 11, an adjustment block 2 12 and two positioning pins 13;

[0026] The adjusting block 11 is provided with a plurality of threaded holes 2 corresponding to the plurality of threaded holes 1, the adjusting block 11 is fixedly connected to the positioning plate 10 by bolts, a plurality of threaded holes 3 are provided on one side wall of the adjusting block 11, a plurality of threaded holes 4 are provided on the adjusting block 2 12 corresponding to the plurality of threaded holes 3, the adjusting block 2 12 is fixedly connected to the adjusting block 11 by bolts, and two positioning pins 13 are detachably fixed on one side of the adjusting block 2 12, and the two positioning pins 13 are diagonally arranged.

[0027] Each of the positioning pins 13 has a diameter of 6.5 mm and a length of 13 mm.

[0028] Working principle:

[0029] When using the automobile backrest backrest lock bracket fixing device, first, the bottom plate 2 of the fixing mechanism is fixed on the frame welding tooling. This fixing action is the basis of the device and ensures that the entire device can work stably.

[0030] Next, by operating the hand-push pliers 1, the positioning plate 10 in the propulsion mechanism is moved. One end of the hand-push pliers 1 is hinged to the fixing mechanism, and the other end is provided with a long hole. The connecting plate 9 in the propulsion mechanism is fixedly connected to the positioning plate 10, and the side wall of the positioning plate 10 is slidably connected to the long hole of the hand-push pliers 1. Therefore, when the hand-push pliers 1 is pushed, the positioning plate 10 will move accordingly. At the same time, since the locking mechanism is fixedly connected to the propulsion mechanism by bolts, the locking mechanism will also move with the movement of the positioning plate 10.

[0031] During the movement of the positioning plate 10, the two diagonally arranged positioning pins 13 in the locking mechanism will gradually approach the backrest lock bracket and finally be inserted into the backrest lock bracket. In this process, the pre-compression effect of the hand push pliers 1 plays a key role, which ensures that the positioning pins 13 can be accurately inserted into the backrest lock bracket, preventing the insertion failure caused by position deviation.

[0032] Before the positioning pin 13 is inserted, a more precise adjustment can be achieved by adjusting the locking mechanism. Specifically, the multiple threaded holes 1 on the positioning plate 10 and the threaded holes 2 on the adjustment block 11 can be connected by bolts to perform fine adjustments in the horizontal direction. Similarly, the multiple threaded holes 3 on the adjustment block 11 and the multiple threaded holes 4 on the adjustment block 2 12 can also be connected by bolts to achieve fine adjustments in the vertical direction. If more subtle adjustments are required, gaskets can also be put on the bolts to achieve the best insertion effect.

[0033] After the positioning pin 13 is inserted, the cylinder 7 in the propulsion mechanism is started. The cylinder 7 is connected to the connecting plate 9 through the pin shaft 8. When the cylinder 7 works, it pushes the connecting plate 9 and the positioning plate 10 connected thereto in the direction of the backrest lock bracket for secondary compression. This secondary compression action can ensure that the backrest lock bracket is firmly fixed on the car seat, improving the stability and reliability of the entire device.

[0034] Through the above working principle, the vehicle backrest backrest lock bracket fixing device can realize fast, accurate and firm fixing of the backrest lock bracket, thereby improving the assembly efficiency and quality of the vehicle seat.

[0035] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other forms of assembly without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes within the meaning and scope of the equivalents of the claims be included in the present invention.
