DETAILED DESCRIPTION

[0072] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0073] A mechanical auxiliary opening device for electric unlocking of a side door of an automobile comprises an auxiliary opening rod 2 rotatably connected to a lock body mounting shell 1, an auxiliary opening rod return spring 3 abutting against the auxiliary opening rod 2, a locking arm stopper 72 provided on a locking arm 7, and a convex column 42 provided on a lock tongue 4. The auxiliary opening rod 2 is provided with a stopper 22 and a pusher 23.

[0074] The auxiliary opening lever 2 has a first working position and a second working position. In the first working position, the locking arm 7 can engage with the locking tongue 4.

[0075] In the second working position, the stopper 22 is located between the locking arm stopper 72 and the lock tongue 4, and the stopper 22 abuts against the locking arm stopper 72, thereby preventing the locking arm 7 from engaging with the lock tongue 4. When the lock tongue 4 rotates until the boss 42 abuts against the push block 23, the auxiliary opening lever 2 is driven to rotate so that the stopper 22 is disengaged from the locking arm stopper 72, and the locking arm 7 can engage with the lock tongue 4 again.

[0076] It should be noted that the auxiliary opening rod 2 being in the first working position and the second working position does not necessarily mean a change in spatial position, but a change in the matching relationship between the auxiliary opening rod 2 and the locking arm 7 .

[0077] Specifically, the first end 2001 of the auxiliary opening rod 2 is rotatably connected to the lock body mounting shell 1, and the stopper 22 is arranged at the second end 2002 of the auxiliary opening rod 2. The side of the stopper 22 facing the second end 2002 forms an end stopper surface 221. When in the second working position, the locking arm stopper 72 abuts against the end stopper surface 221. The side of the stopper 22 facing the first end 201 forms a slope surface 222. When the auxiliary opening rod 2 switches from the first working position to the second working position, the locking arm stopper 72 moves against the slope surface 222. Specifically, in this embodiment, the cross section of the stopper 22 can be a triangle.

[0078] The push block 23 is disposed between the first end 2001 and the second end 2002 of the auxiliary opening rod 2 and is located on a side of the auxiliary opening rod 2 close to the locking tongue 4 .

[0079] More specifically, the auxiliary opening rod 2 includes a segment 1 close to the first end 2001, a segment 2 provided with the above-mentioned push block 23, a segment 4 24 provided with the above-mentioned stop block 22, and a segment 3 obliquely connected between the segment 2 and the segment 4 24.

[0080] The lock body mounting shell 1 has a first surface and a second surface opposite to the first surface, and the locking arm 7 and the lock tongue 4 are installed on the first surface; the first end 2001 of the auxiliary opening rod 2 is provided with a mounting hole 21, and the mounting hole 21 is matched with the auxiliary opening rod mounting column protruding from the second surface, so that the block 22 cooperates with the locking arm block 72 after passing through the lock body mounting shell 1, and the push block 23 cooperates with the protruding column 42 after passing through the lock body mounting shell 1.

[0081] A window 11 is provided on the lock body mounting shell 1, which passes through the first surface and the second surface thereof, and a lock body mounting shell convex portion 12 is formed by arching on the second surface of the lock body mounting shell 1. The above-mentioned segment body 24 abuts against the lock body mounting shell convex portion 12 to form a limit for the auxiliary opening rod 2 and the lock body mounting shell 1, so that the auxiliary opening rod return spring 3 and the lock body mounting shell convex portion 12 cooperate to keep the auxiliary opening rod 2 in the first working position or in the second working position. Of course, the above-mentioned lock body mounting shell convex portion 12 is not necessarily formed by the arching of the lock body mounting shell 1, but can be other parts, and is not specifically limited.

[0082] More specifically, if Figure 1 As shown, a mechanical auxiliary opening device for electric unlocking of a vehicle side door includes a lock body mounting shell 1, an auxiliary opening rod 2, an auxiliary opening rod reset spring 3, a lock tongue 4, a lock tongue pin 5, a lock tongue reset spring 6, a locking arm 7, a locking arm pin 8, a locking arm driving arm 9 and a locking arm driving arm reset spring 10, etc.

[0083] A mounting hole 21 is provided at one end of the auxiliary opening rod 2, and a block 22 is vertically provided at the other end. An end stop surface 221 is provided on the side of the block 22 away from the mounting hole 21, and a slope 222 is provided on the side of the block 22 close to the locking arm 7, climbing from the outside to the inside; a push block 23 is vertically provided on the middle part of the auxiliary opening rod 2 close to the lock tongue 4.

[0084] The auxiliary opening rod 2 is sleeved on a mounting column of the lock body mounting shell 1 and can rotate around the mounting column. When the auxiliary opening rod 2 rotates and falls into the inner side of the end block 22 of the locking arm 7, the locking arm 7 is blocked and cannot engage with the lock tongue 4 again to achieve the locking action; when the auxiliary opening rod 2 rotates in the opposite direction and disengages from the inner side of the end block 22 of the locking arm 7, the locking arm 7 is released, allowing the locking arm 7 to engage with the lock tongue 4 again to achieve the locking action.

[0085] An auxiliary opening rod 2 mounting column is provided on one side of the lock tongue 4 of the lock body mounting shell 1, and the mounting column is arranged on the other side of the lock body mounting shell 1 where the lock tongue 4 and the locking arm 7 are installed. In other words, the auxiliary opening rod 2 is arranged on the other side of the lock body mounting shell 1 relative to the fish mouth opening; an auxiliary opening rod return spring 3 mounting column is provided on one side of the locking arm 7 of the lock body mounting shell 1, and the auxiliary opening rod return spring 3 has a fixed arm that resists the side wall of the lock body mounting shell 1, and the other working arm elastically presses the outside of the auxiliary opening rod 2 block 22.

[0086] like Figure 2 As shown, a mounting hole 71 is provided in the middle of the locking arm 7, an engaging arc surface 74 is provided at one end of the locking arm 7, a stopper 72 is provided outside the engaging arc surface 74, a rotating arm 73 is extended from the other end of the locking arm 7, and a positioning groove 731 is provided on one side wall of the rotating arm 73.

[0087] like Figure 3 As shown, the lock tongue 4 has a mounting hole 41 in the middle, a lock column engaging groove 43 on one side, and a protrusion 42 vertically arranged on the other side; a half-lock engaging surface 44 and a full-lock engaging surface 45 are arranged on one side of the lock column engaging groove 43.

[0088] like Figure 4The figure shows a partial view of the door lock in the closed state (fully locked position engaged); when the locking arm driving arm 9 is acted upon by an external force (electric opening or pulling the emergency pull wire), the locking arm 7 is driven to rotate counterclockwise around the locking arm pin 8, and the end block 72 of the locking arm 7 rotates to push the slope 222 on one side of the block 22 of the auxiliary opening rod 2, and the auxiliary opening rod 2 is lifted up, as shown in FIG. Figure 5 As shown; until the end stopper 72 of the locking arm 7 rotates out of the end stopper 221 of the stopper 22 of the auxiliary opening rod 2, the auxiliary opening rod 2 rotates and returns to the initial position under the torsion of the auxiliary opening rod return spring 3, at this time, after the external force acting on the locking arm driving arm 9 (electric opening or pulling the emergency pull wire) is released, the locking arm 7 and the locking arm driving arm 9 have a tendency to rotate and return under the action of the locking arm driving arm return spring 10, but because one side of the stopper 72 of the locking arm 7 is blocked by the end stopper 221 of the auxiliary opening rod 2, the locking arm stopper 72 is limited outside the end stopper 221 of the auxiliary opening rod 2 and the locking arm 7 and the lock tongue 4 cannot be re-engaged (neither full locking nor half locking is allowed). Figure 6 Only when the door is opened, the lock column pulls the lock tongue 4 to rotate until the lock tongue 4 protrusion 42 rotates and pushes the auxiliary opening rod 2 (the door lock is in the fully open state), and the stopper 22 of the auxiliary opening rod 2 releases the locking arm 7, allowing the locking arm 7 to engage with the lock tongue 4 again (allowing re-locking), as shown in FIG. Figure 7 , Figure 8 shown.

[0089] like Fig. 9 As shown, an electric unlocking device for a vehicle side door comprises a lock body assembly 01 , an actuator assembly 02 , a cover plate 03 and a combined accessory 04 connecting the lock body assembly 01 , the actuator assembly 02 and the cover plate 03 .

[0090] like Fig.10 As shown, the lock body assembly 01 at least includes a lock body mounting shell 101, a mounting plate 107, a lock tongue 108, a lock tongue pin 109, a lock tongue return spring 110, a locking arm 105, a locking arm pin 104, a locking arm driving arm 113, a locking arm driving arm return spring 112, a locking rocker arm 117, a locking link 120, a locking link return spring 115, an auxiliary opening rod 118, an auxiliary opening rod return spring 119, etc.

[0091] The locking arm 105 and the locking arm driving arm 113 may be two independent components, or may be connected to the same component, without any specific limitation.

[0092] A protruding column 108 a is vertically arranged on one side of the plane of the lock tongue 108 , and one end of the lock tongue pin 109 passes through the lock tongue 108 and the lock tongue return spring 110 in sequence and is riveted to the mounting plate 107 .

[0093] A stopper 105 a is provided at one end of the locking arm 105 , and a rotating arm 105 b is extended from the other end. One end of the locking arm pin 104 passes through the locking arm 105 and is riveted to the mounting plate 107 .

[0094] The other ends of the bolt pin 109 and the locking arm pin 104 pass through the lock body mounting shell 101 and extend outside the lock body mounting shell 101. The locking arm driving arm return spring 112, the locking arm driving arm 113, and the outward opening rocker arm 122 pass through the other end of the locking arm pin 104 in sequence.

[0095] The other ends of the lock tongue pin 109 and the locking arm pin 104 are riveted with a connecting plate 121, and a backup locking knob 114 is installed between the lock body mounting shell 101 and the connecting plate 121; a first rotating shaft 101a is provided on one side of the upper part of the lock body mounting shell 101, and an auxiliary opening rod 118 is sleeved on the first rotating shaft 101a, and a push block 118a is vertically provided on the side of the auxiliary opening rod 118 close to the lock tongue 108, and a stopper 118b is vertically provided on the other end of the auxiliary opening rod 118, and the stopper 118b is inclined near a side of the locking arm 105, and an auxiliary opening rod return spring 119 is sleeved on one side of the stopper 118b at the other end of the auxiliary opening rod 118 inside the lock body mounting shell 101.

[0096] The auxiliary opening lever 118 has a first working position and a second working position. In the first working position, the locking arm 105 is engaged with the locking tongue 108 .
