[0031] In specific implementation, the lock body assembly of the present invention is assembled as follows: 1) Lock body sub-assembly: The self-priming rocker arm buffer block 27, the lock buckle shock-absorbing pad 26, and the ratchet shock-absorbing pad 11 are respectively mounted on the lock body 12, and the ratchet signal device 13 and the ratchet signal rocker arm signal device 14 are respectively mounted on the above sub-assembly; 2) Ratchet assembly subassembly: riveting the ratchet self-priming shaft 31 on the ratchet 3; 3) Self-priming rod sub-assembly: Rivet the self-priming rod limiting shaft 25 on the self-priming rod 24; 4) Self-priming rocker arm sub-assembly: Rivet the self-priming transmission shaft 16 on the self-priming rocker arm 15; 5) Self-priming component subassembly: Install the self-priming rod return spring 23 on the self-priming rocker arm linkage shaft 22, and then install the self-priming rocker arm 21, the self-priming rod 24, and the stainless steel washer 30 in sequence and rivet them; 6) Front cover sub-assembly: pass the ratchet shaft 2 through the ratchet 3 and the front cover 1, and rivet them at the bottom of the bottom plate; pass the pawl shaft 5 through the pawl signal rocker arm return spring 9, the pawl signal rocker arm 8, the pawl return spring 4, the pawl 7 and rivet them at the bottom; pass the connecting shaft 10 through the bottom plate and rivet them at the bottom; put the front cover sub-assembly into the lock body 12; 7) Place the self-priming rocker arm shaft A19 in the above-mentioned sub-assembly and rivet it at the bottom of the front cover 1. After riveting, put on the self-priming rocker arm return spring A20 and the rear cover 28 of the self-priming component sub-assembly and fix them at four positions with rivets.

[0032] The present invention has the following functions: 1) Opening function: The pawl 7 rotates around the pawl shaft 5 under the action of the opening wire 32, so that the pawl surface a7-1 and the ratchet surface a3-1 are out of meshing relationship. The ratchet 3 is reset around the ratchet shaft 2 under the action of the ratchet return spring 4, so that the ratchet surface b3-2 contacts the pawl shock pad 11 until the ratchet 3 is fully opened, realizing the door lock opening function, thereby feeding back the door lock ratchet opening signal to the BCM, such as Figure 4-5 shown.

[0033] The pawl 7 is opened, and the pawl 7 is engaged with the ratchet wheel 3 to bear the lock body load. The pawl signal rocker arm surface b8-2 contacts the pawl signal rocker arm signal device 14, thereby feeding back the position state of the pawl signal rocker arm 8, such as Figure 12-13 shown.

[0034] 2) Self-priming function: When the door is closed by external force, the lock enters the slot of the ratchet 3, and the ratchet 3 rotates around the ratchet shaft 2. At the same time, the ratchet surface c 3-3 pushes the pawl 7 to rotate around the pawl shaft 5. When the ratchet 3 moves to the semi-locked position, Figure 6-7As shown, the pawl 7 is reset under the action of the pawl return spring 6, the pawl meshing surface 7-1 is engaged with the ratchet meshing surface d 3-4, and at the same time the ratchet surface e 3-5 is in contact with the ratchet signal device surface 13-1, the pawl signal rocker arm surface a 8-1 is in contact with the ratchet surface e 3-5, and the pawl signal rocker arm surface b 8-2 still remains disengaged from the pawl signal rocker arm signal device 14; the combination of the above signals triggers the door lock to enter a semi-locked state, thereby performing a self-priming action. The half-locked state signal is fed back to the vehicle body through the door lock harness connector. The body external actuator pulls the self-priming wire 33 to drive the self-priming rod 24, the self-priming rocker arm linkage shaft 22, and the self-priming rocker arm 21 to move around the self-priming rocker arm shaft 19. The self-priming rod surface a 24-1 pulls the ratchet self-priming shaft 31 to link the ratchet 3 to move around the ratchet shaft 2, so that the ratchet surface c 3-3 pushes the pawl 7 to make way around the pawl shaft 5. When the ratchet 3 moves to the fully locked position, the pawl 7 is reset under the action of the pawl return spring 6, and the pawl surface 7-1 engages with the ratchet surface a 3-1 to realize the self-priming function. Figure 18-21 shown.

[0035] At the same time, the ratchet wheel 3 contacts the ratchet signal device 13, and the ratchet signal rocker arm 8 presses the ratchet signal rocker arm signal device 14; the signal is fed back to the vehicle body through the wiring harness connector, indicating that the side door is in a fully locked state, thereby terminating the self-priming action. The self-priming rod 24 is reset around the self-priming rocker arm shaft A19 along with the self-priming rocker arm A21 under the action of the self-priming rocker arm return spring A20; from then on, the self-priming function execution movement is completed.

[0036] The self-priming rod 24 resets and moves, such as Fig.23 As shown, the self-priming rod 24 moves from the self-priming position to the left side of the figure under the drive of the self-priming rocker arm 27, and the self-priming rod 24 moves around the self-priming rocker arm linkage shaft 22 under the action of the self-priming rod return spring 23, so that the self-priming rod limit shaft 25 moves and resets along the lock body surface 12-1.

[0037] 3) Self-priming insurance opening function: The lock body is provided with a self-priming rocker arm 15 and a self-priming rocker arm return spring 18. The self-priming rocker arm 15 is provided with a self-priming transmission shaft 16. When the self-priming rod 24 is affected by something and fails to reset after self-priming, the ratchet 7 can be pulled, and the ratchet 7 rotates around the ratchet shaft 5, and the self-priming rocker arm B surface 15-1 is pushed to rotate around the self-priming rocker arm shaft B17 through the ratchet surface b 7-2, and then the self-priming rod surface b 24-2 is pushed to rotate around the self-priming rocker arm linkage shaft 22 through the self-priming transmission shaft 16 provided on the self-priming rocker arm B15, so that the self-priming rod surface a 24-1 is separated from the ratchet self-priming shaft 31, as shown in FIG. Figure 12-13 As shown, after disengagement, the ratchet 3 rotates and resets around the ratchet shaft 2 under the action of the ratchet return spring 4, realizing the self-priming safety opening function. At the same time, the self-priming rod 24 is reset around the self-priming rocker arm linkage shaft 22 under the action of the self-priming rod return spring 23; the next electric self-priming function can be cyclically executed later.

[0038] 4) Door lock opening signal: When the ratchet 3 is in the open state, the ratchet 3 is in limited contact with the ratchet pawl shock pad 11 and has no contact with the ratchet signal device 13; the ratchet 7 is in limited contact with the ratchet pawl shock pad 11, and the ratchet signal rocker arm 8 is kept disengaged from the ratchet signal rocker arm signal device 14 under the action of the ratchet signal rocker arm return spring 9; the signal is fed back to the vehicle body through the wiring harness connector, indicating that the door is in the open state, such as Figure 4-5 shown.

[0039] 5) Door lock half-lock signal: When the ratchet wheel 3 is in the half-lock state, the ratchet wheel 3 is in meshing contact with the pawl 7, and the ratchet wheel 3 begins to contact with the ratchet signal device 13; the pawl 7 is in limited contact with the pawl shock-absorbing pad 11, and the pawl signal rocker arm 8 is kept disengaged from the pawl signal rocker arm signal device 14 under the action of the pawl signal rocker arm return spring 9; the feedback is fed back to the vehicle body through the connector, indicating that the door is already in the half-lock state, such as Figure 6-7 shown.

[0040] 6) Door lock full lock signal: When the ratchet 3 is in the full lock state, the ratchet 3 is in meshing contact with the pawl 7, the ratchet 3 is in contact with the ratchet signal device 13, and the pawl signal rocker arm 8 presses the pawl signal rocker arm signal device 14; the signal is fed back to the vehicle body through the wiring harness connector, indicating that the side door is in the full lock state, such as Figure 8-9 shown.

The electrically opened and self-priming integrated mechanical lock body according to claim 1, characterized in that: The front end of the self-priming rod (24) is configured to be hook-shaped and is used to drive the ratchet self-priming shaft (31) to link the ratchet (3) to move around the ratchet shaft (2) so that the pawl (7) and the ratchet (3) are meshed, thereby realizing the self-priming function of the door lock.

7. The electrically opened and self-priming integrated mechanical lock body according to claim 1, characterized in that: The head of the ratchet (7) is provided with a raised portion. When the self-priming rod (24) fails to reset after self-priming, the raised portion of the ratchet (7) pushes the self-priming rocker arm B (15) to rotate around the self-priming rocker arm shaft B (17). The self-priming transmission shaft (16) pushes the self-priming rod (24) to disengage from the ratchet self-priming shaft (31), thereby resetting the ratchet (3) and realizing the self-priming safety opening function.
