[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figures 1-4 , the present utility model provides the following technical solutions: A positioning tooling for automotive seats, including a bottom plate layer 1, a rotating layer 2, a flipping layer 3, a positioning quick-change layer 4 and a sliding mechanism 5. The bottom plate layer 1, the rotating layer 2, the flipping layer 3 and the positioning quick-change layer 4 are sequentially connected upward. The seat frame is fixed on the positioning quick-change layer 4. The sliding mechanism 5 is located between the positioning quick-change layers 4. The sliding mechanism 5 enables one side of the positioning quick-change layer 4 to slide. The sliding mechanism 5 includes a lock catch 501, a lock rail 502, a slider 503 and a slide rail 504. The lock rail 502 is fixedly embedded on one side edge of the positioning quick-change layer 4. The lock catch 501 is adapted to the lock rail 502 and is movably connected to one side edge of the positioning quick-change layer 4. Lock slots 5021 are opened at both ends of the side of the lock rail 502. When the positioning quick-change layers 4 are combined, the lock catch 501 is stuck in a lock slot 5021. When the cylinder outside the assembly line pushes the lock catch 501 out of a lock slot 5021, the internal spring of the positioning quick-change layer 4 pushes one side of the positioning quick-change layer 4 to shift until the lock catch 501 is stuck in another lock slot 5021. At this time, the positioning quick-change layer 4 is separated to divide the rear row seat into a 40% seat and a 60% seat. The positioning quick-change layer 4 can achieve the functions of quick fastening and quick disassembly, so that different models of positioning quick-change layers 4 can be adapted to different models of rear row seats.

[0030] Specifically, please refer to Figure 5 , the bottom plate layer 1 includes a bottom plate 101, and the size of the bottom plate 101 is matched with the assembly line to ensure that the tooling does not move randomly on the assembly line.

[0031] Specifically, please refer to Figures 5-7, the rotating layer 2 includes a bearing 201, four limit movable blocks 202, a rotation unlocking mechanism, and a rotating plate 208. The bearing 201 is fixed to the bottom plate 101 at the bottom and rotatably connected to the rotating plate 208 at the top. When manually rotating, the bearing 201 drives the rotating plate 208 and the above parts to rotate, and the bottom plate 101 remains stationary. The tops of the four limit movable blocks 202 are fixed to the four side parts of the rotating plate 208 and are square. The limit movable blocks 202 are located outside the bearing 201. The rotation unlocking mechanism is fixed to the bottom plate 101 and cooperates with the limit movable blocks 202. Pull the rotation unlocking mechanism, the rotation unlocking mechanism disengages from the limit movable blocks 202, and after the rotating plate 208 rotates 90° each time, loosen the rotation unlocking mechanism and it can automatically latch with the limit movable blocks 202 on the side. The rotating plate 208 can also rotate 360° and then loosen the rotation unlocking mechanism to automatically latch with the limit movable blocks 202 on the side.

[0032] Specifically, the rotation unlocking mechanism includes two rotating handles 203, several limit fixing pins 204, a movable plate 205, a fixing plate 206, and an upper fixing plate 207. The movable plate 205 is located on the right side of the bottom plate 101 and outside the limit movable blocks 202. Several horizontal waist holes 2051 are formed in the movable plate 205. The limit fixing pins 204 are fixed to the bottom plate 101 and inserted into the waist holes 2051. When the movable plate 205 moves left and right, the waist holes 2051 slide along the limit fixing pins 204 within a limited length left and right. Grooves 2052 are respectively formed on the upper and lower sides of the movable plate 205. One end of the rotating handle 203 is clamped into the groove 2052. A groove 2053 adapted to the limit movable blocks 202 is formed on the left side of the movable plate 205. In the locked state, the lower part of the limit movable blocks 202 is clamped with the groove 2053. The fixing plate 206 is fixed to the right side of the movable plate 205. There is a gap between the fixing plate 206 and the movable plate 205 in the locked state. A spring is connected between the fixing plate 206 and the movable plate 205. The upper fixing plate 207 is located above the movable plate 205 and the fixing plate 206.

[0033] The movement principle of the rotation unlocking mechanism is: when unlocking is required, first pull the two rotating handles 203 at both sides backward all the time. The backward movement of the rotating handles 203 drives the waist holes 2051 on the movable plate 205 to slide along the limit fixing pins 204 within a limited length left and right, so that the limit movable blocks 202 disengage from the groove 2053. At this time, the spring between the fixing plate 206 and the movable plate 205 is compressed and has a restoring force. Manually rotate the rotating plate 208 to the required position, and then release the rotating handles 203. The movable plate 205 automatically moves forward under the action of the spring and the groove 2053 clamps the limit movable blocks 202, thus realizing automatic locking.

[0034] Specifically, please refer to Figures 7-9, the flipping layer 3 includes a flipping plate 301, two gas springs 302 and two flipping link mechanisms. The gas springs 302 are connected to the flipping link mechanisms and are located on the left and right sides above the rotating plate 208. The flipping plate 301 is connected to the flipping link mechanisms and the flipping plate 301 is located above the two gas springs 302 and the two flipping link mechanisms. When it is necessary to flip the flipping plate 301, after unlocking the flipping link mechanisms on both sides, with the assistance of the gas springs 302 on both sides, the operator can easily flip the flipping plate 301 and the parts above it upwards.

[0035] Specifically, the flipping link mechanism includes a movable handle 303, a fixed handle 304, several first fixing blocks 305, a second fixing block 306, a worm gear rod 307 and a connecting rod 308. The worm gear rod 307 is fixed to the side of the rotating plate 208. One end of the worm gear rod 307 is in the shape of a worm gear and several card slots 3071 are opened on its outer circumference. The angles of the card slots 3071 are designed according to different requirements of the flipping angles. One end of the connecting rod 308 is designed as a tooth 3081 adapted to the card slot 3071, and the other end is connected to the movable handle 303. A spring is also sleeved on the connecting rod 308. In the locked state, the tooth 3081 is inserted into the card slot 3071. Several first fixing blocks 305 are movably sleeved on the connecting rod 308. The first fixing blocks 305 are movably sleeved on the front and rear ends of the connecting rod 308 so that the connecting rod 308 can move linearly and stably back and forth in the first fixing blocks 305. The upper part of the first fixing blocks 305 is fixed to the lower surface of the flipping plate 301. The second fixing block 306 is fixed to the front end of the lower surface of the flipping plate 301. The side of the second fixing block 306 is fixedly connected to the fixed handle 304, so that the operator can easily flip the flipping plate 301 upwards by relying on the fixed handle 304 during flipping. During flipping, the worm gear rod 307 and the rotating plate 208 are horizontally stationary, and the flipping plate 301 drives the connecting rod 308, the movable handle 303 and the fixed handle 304 to rotate upwards together.

[0036] The movement principle of the flipping link mechanism is as follows: When flipping is required, first pull the movable handles 303 on both sides continuously so that the tooth 3081 disengages from the card slot 3071. At this time, the spring on the connecting rod 308 is compressed and has a restoring force. Then, when the operator grabs the fixed handles 304 on both sides and flips the flipping plate 301 to an appropriate angle, at this time, the two gas springs 302 will assist in flipping upwards, and the operator can easily flip the flipping plate 301 and the parts above it to an appropriate angle. Then release the movable handles 303 so that the tooth 3081 automatically inserts into the card slot 3071 at an appropriate angle again, and it is locked again.

[0037] Specifically, please refer to Figures 3-4With respect to 10, the positioning quick-change layer 4 includes a quick-change plate one 401, a quick-change plate two 402, two quick-change mechanisms and a positioning mechanism. The quick-change plate two 402 is fixed on the upper surface of the flipping plate 301. The two quick-change mechanisms fix the quick-change plate two 402 on the flipping plate 301. The two quick-change mechanisms are located on the left and right sides of the quick-change plate two 402. The quick-change plate one 401 is located on the upper surface of one side of the quick-change plate two 402. 40% of the seat part is fixed on the quick-change plate one 401, and 60% of the seat part is fixed on the quick-change plate two 402. A sliding mechanism 5 is arranged between the quick-change plate one 401 and the quick-change plate two 402. The quick-change plate one 401 slides on the quick-change plate two 402 through the sliding mechanism 5, so that the rear seat can separate the 40% seat part and the 60% seat part, and assemble them separately, improving the convenience of assembly.

[0038] Specifically, the quick-change mechanism includes a quick-change handle 403, a pin 404 and a positioning pin 405. Spring screws 4031 are arranged on both sides of the quick-change handle 403, and a handle positioning pin 4032 is arranged in the middle. After the handle positioning pin 4032 is inserted into the flipping plate 301, the bottom dimension of the handle positioning pin 4032 is large and is fixed at the bottom of the flipping plate 301, thus realizing the first layer of fixation. The pin 404 passes through the quick-change plate two 402 and the flipping plate 301, which realizes the second layer of fixation. A positioning hole 406 adapted to the positioning pin 405 is opened on the quick-change plate two 402. After the positioning pin 405 passes through the positioning hole 406, the quick-change plate two 402 is pushed, and the positioning pin 405 then passes through the flipping plate 301, which realizes the third layer of fixation. The top end of the positioning pin 405 is oval-shaped. When the positioning pin 405 is fixed, the top end of the positioning pin 405 abuts against the quick-change plate two 402 beside the positioning hole 406. The triple fixation has a strong protective effect.

[0039] The movement principle of the quick-change mechanism is as follows: When fixing, first insert the positioning pin 405 into the positioning hole 406 and then push the quick-change plate two 402. After the positioning pin 405 automatically slides into the flipping plate 301, it is fixed. Then, the spring screws 4031 on both sides of the quick-change handle 403 are fixed on the quick-change plate two 402, and the handle positioning pin 4032 in the middle is fixed at the bottom of the quick-change plate two 402. Finally, the pin 404 passes through the quick-change plate two 402 and the flipping plate 301 to realize the fixation; when the plate needs to be changed, first pull out the pin 404, then push the quick-change plate two 402 and pull out the positioning pin 405. Finally, lift the quick-change handle 403, and the handle positioning pin 4032 is separated from the flipping plate 301, and then the plate can be changed.

[0040] Specifically, please refer to Figures 10-14, a sliding plate 409 is fixed to the rear side of the quick-change plate 402, and a sliding plate 410 is fixed to the rear side of the quick-change plate 401. The positioning mechanism includes a number of front positioning pins 407, a number of rear positioning pins 408, and two seat unlocking mechanisms 411. The number of front positioning pins 407 is installed on the front side edges of the quick-change plate 401 and the quick-change plate 402. The front positioning pins 407 are fixed type, fixing the lower part in front of the seat. The number of rear positioning pins 408 is installed on the upper surfaces of the sliding plate 409 and the sliding plate 410. A groove is provided at the top of the rear positioning pin 408. The rear positioning pins 408 are spring self-locking type. The rear positioning pins 408 fix the lower part at the rear side of the seat, and the groove at the top of the rear positioning pin 408 is fixed under the action of the seat unlocking mechanism 411. One ends of the two seat unlocking mechanisms 411 are respectively connected to the front sides of the sliding plate 409 and the sliding plate 410. One seat unlocking mechanism 411 is located on the quick-change plate 401, and the other seat unlocking mechanism 411 is located on the quick-change plate 402. The seat unlocking mechanism 411 has elasticity.

[0041] The seat fixing and unlocking principle is as follows: The seat fixing principle is that the lower part in front of the seat is fixed on the front positioning pin 407, then the rear positioning pin 408 is pressed to match the lower part at the rear side of the seat, and then the pressing is released, and the seat is buckled in the rear positioning pin 408 by the rebound of the seat unlocking mechanism 411 to achieve fixation; The seat unlocking principle is that the sliding plate 409 and the sliding plate 410 are pushed forward by the external cylinder of the production line, and the two seat unlocking mechanisms 411 are pushed forward. Therefore, the groove on the rear positioning pin 408 is separated from the seat, and the seat can be removed.

[0042] Specifically, please refer to Figures 3-4 , a locking rail 502 is arranged on the rear side edge of the quick-change plate 401. The lower part of the locking buckle 501 is stuck on the rear side edge of the quick-change plate 402, and the upper part is stuck in the locking groove 5021. Sliding rails 504 are fixed to the front and rear sides under the quick-change plate 401. Sliders 503 adapted to the sliding rails 504 are fixed to the front and rear sides on the quick-change plate 402. The sliders 503 are fixed, and the quick-change plate 401 drives the sliding rails 504 to slide on the sliders 503.

[0043] The sliding principle of the sliding mechanism 5 is as follows: First, the external cylinder of the production line pushes the locking buckle 501 out of a locking groove 5021, and the internal spring of the positioning quick-change layer 4 pushes the quick-change plate 401 to slide until the locking buckle 501 is stuck in another locking groove 5021, and the seat positioning tooling is separated; When the seat positioning tooling needs to be combined, the worker directly pushes the quick-change plate 401 inward, and then the locking buckle 501 is stuck in the outer locking groove 5021.
