[0007] The stop claw B is engaged with the transition lock position of the clamping plate;

[0008] In the fully locked position, the locking claw A elastically abuts against the locking claw B along its unlocking direction;

[0009] When the locking claw A is pulled for the first time to unlock, the locking claw A drives the locking claw B to rotate and open together;

[0010] In the transition lock position, the card plate is engaged with the stop claw B, and the stop claw A cannot drive the stop claw B to continue to rotate and open, and the stop claw A opens to the maximum position alone;

[0011] When the stop claw A is reset from the maximum open position, the stop claw B can be driven at the same time to be reset together with the stop claw A to the initial position.

[0012] Furthermore, the card plate has a full-locking engagement portion, a half-locking engagement portion and a transitional locking engagement portion; the stopping claw A has a stopping claw A driving portion, a stopping claw A locking portion and a stopping claw A operating portion; the stopping claw B has a stopping claw B force-bearing portion and a stopping claw B stopping portion.

[0013] Furthermore, in the fully locked position, the locking portion of the stop claw A engages with the fully locked engaging portion of the card plate; in the half-locked position, the locking portion of the stop claw A engages with the half-locked engaging portion of the card plate; in the transitional lock position, the filter lock engaging portion of the card plate engages with the stop claw B stop portion.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in this embodiment to clearly and completely describe the technical solutions in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] Embodiment 1

[0037] The invention discloses a double-pull opening locking mechanism for automobiles, which is particularly suitable for automobile hood lock mechanisms. The mechanism can cooperate with a vehicle body lock pin to realize a double-position locking function of the automobile hood lock, and can realize a double-position unlocking function by pulling a stop claw twice.

[0038] The double-pull opening locking mechanism includes: a base plate 1, a clamping plate 2, a stop claw A3, a stop claw B4, a stop claw A spring 5, a stop claw B spring 6, a clamping plate spring 7, a stop claw shaft 8, and a clamping plate shaft 9.

[0039] like Figure 1 As shown, the lock body has a base plate 1, a stop claw A3, and a stop claw B4 which are coaxially and pivotally fixed on the base plate 1 by a stop claw shaft 8; the card plate 2 is pivotally fixed on the base plate 1 by a card plate shaft 9; the stop claw A3 is matched with a stop claw A reset spring 5, and the stop claw A reset spring 5 can reset the stop claw A3 from the open position to the initial position; the card plate 2 is matched with a card plate spring 7, and the card plate spring 7 can rotate the card plate 2 from the fully locked position to the maximum open position. The stop claw B4 is matched with a stop claw B reset spring 6, and one end of the stop claw B reset spring 6 is connected to the stop claw B4, and the other end is connected to the stop claw A3. Through the action of the stop claw B reset spring 6, the stop claw A driving part 31 can be abutted against the stop claw B force bearing part 41, so that the stop claw A3 and the stop claw B4 are softly connected as a whole.

[0040] Figure 2 It is a schematic diagram of the state of the lock body in the fully locked position, at which time all parts are in the initial position; the locking portion 32 of the stop claw A is engaged with the card plate fully locked engaging portion 21, and the stop claw A3 locks the card plate 2 in the fully locked position.

[0041] The first time you turn it on, Figure 3 As shown, the stop claw A operating portion 33 is pulled to rotate the stop claw A3 in the opening direction. At this time, due to the mutual abutment relationship between the stop claw A driving portion 31 and the stop claw B force receiving portion 41, when the stop claw A3 rotates to open, it will also drive the stop claw B4 to rotate and open together.

[0042] like Figure 4 As shown, the stop claw A3 and the stop claw B4 continue to rotate to open. When the stop claw A3 rotates until its stop claw A locking portion 32 is disengaged from the card plate full lock engaging portion 21, the stop claw A3 releases the lock on the card plate 2, and the card plate 2 rotates to open under the action of the card plate spring 7. When the card plate 2 rotates until its card plate transition lock engaging surface 23 abuts against the stop claw B stop portion 42, the stop claw B4 is blocked by the card plate 2 and stops rotating, and the lock body is in the transition lock position.

[0043] like Figure 5As shown, the first pulling process continues. At this time, the stop claw B4 cannot continue to rotate because it is blocked by the clamping plate 2. The stop claw A3 rotates until its stop claw A driving part 31 disengages from the abutment with the stop claw B force-bearing part 41, and the stop claw A3 and the stop claw B4 are separated. At this time, the stop claw A3 can only be driven to move to the maximum opening position.

[0044] After the first pulling is completed, under the action of the stop claw A reset spring 5, the stop claw A3 starts to rotate and reset. When the stop claw A3 rotates to the position where its stop claw A driving part 31 is reset and contacts the stop claw B force receiving part 41, the stop claw A3 can also drive the stop claw B4 to rotate and reset together. The overall position is as shown in FIG. Figure 4 shown.

[0045] like Figure 6 As shown, the locking claw A3 continues to drive the locking claw B4 to rotate and reset until the locking claw A3 drives the locking claw B4 to reset to the initial position together, and the stopping portion 42 of the locking claw B is disengaged from the engaging portion 23 of the card transition lock.

[0046] like Figure 7 As shown, when the stop portion 42 of the stop claw B disengages the restriction on the card board transition lock engaging portion 23, the card board 2 continues to rotate in the opening direction under the action of the card board spring 7, and rotates until the card board semi-locking engaging portion 22 engages with the locking portion 32 of the stop claw A, and the lock body is in a semi-locked position.

[0047] The second opening operation is as follows Figure 8 As shown, when the lock body is in the half-locked state, the locking claw A operating portion 33 of the locking claw A3 is pulled again, and at this position the locking claw B stop portion 42 is blocked by the card plate transition lock engaging portion 23.

[0048] like Fig. 9 As shown, the second pulling process continues until the pawl A3 rotates until its pawl A driving portion 31 is separated from the pawl B force receiving portion 41 , at which time only the pawl A3 can move to the maximum open position.

[0049] like Fig.10 As shown, when the stop claw A3 rotates until its stop claw A locking portion 32 disengages from the card plate semi-locking engagement portion 22, the card plate 2 can continue to rotate open under the action of the card plate spring 7 and move to the maximum open position. At this time, the stop claw B4 can also continue to rotate to the maximum open position.

[0050] like Fig.11 As shown, after the second pulling, the stop claw A3 is reset, and the locking portion 32 of the stop claw A abuts against the half-locking engaging portion 22 of the card plate, and the lock body is in the fully open position.

[0051] like Fig.12As shown, the card plate 2 is now rotated and locked under the push of the locking pin; the card plate semi-locking engaging portion 22 drives the locking portion 32 of the stop claw A, thereby driving the stop claw A3 to rotate and open; at the same time, the card plate transition lock engaging portion 23 drives the stop claw B stopping portion 42, thereby driving the stop claw B4 to rotate and open.

[0052] The card plate 2 continues to rotate to the semi-locked position, the stop claw A3 returns to the initial position, the locking portion 32 of the stop claw A engages with the card plate semi-locked engaging portion 22, and the lock body is in the semi-locked position. Figure 7 shown.

[0053] like Fig.13 As shown, the card plate 2 continues to rotate and lock, and the card plate full-lock engagement portion 21 drives the locking portion 32 of the stop claw A, thereby driving the stop claw A3 to rotate and open;

[0054] The card plate 2 continues to rotate to the fully locked position, the stop claw A3 returns to the initial position, the locking portion 32 of the stop claw A engages with the card plate fully locked engagement portion 21, and the lock body is in the fully locked position. Figure 2 shown.

[0055] Although the embodiments of the present invention have been shown and described above, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
