Fig. 5 is a structural schematic diagram of a second perspective of the dual-lock linkage mechanism 100 according to the embodiment of the invention, fig. 6 is a structural schematic diagram of a safety structure 130 of the dual-lock linkage mechanism 100 according to the embodiment of the invention, and fig. 7 is a structural schematic diagram of a limiting plate 134 of the dual-lock linkage mechanism 100 according to the embodiment of the invention, please refer to fig. 5 to fig. 7.

The safety structure 130 includes a rotation shaft 132, a safety handle 131 and a limit plate 134, and the safety handle 131 is used for being dialed by fingers to rotate.

A slot 1341 is formed in one side of the limiting plate 134 close to the rotating shaft 132, a rotating block 133 is sleeved in the middle of the rotating shaft 132, and the rotating block 133 is clamped into the slot 1341.

A protrusion 1343 is disposed at one end of the limiting plate 134 away from the rotating shaft 132, a positioning groove 1161 is disposed at the lower end of the first limiting block 115 and the lower end of the second limiting block 116, and the position of the positioning groove 1161 corresponds to the position of the protrusion 1343. The protrusion 1343 is inserted into the positioning slot 1161, and the protrusion 1343 can move relatively along the positioning slot 1161, so that the positioning slot 1161 guides and positions the protrusion 1343.

The middle part of limiting plate 134 is equipped with square hole 1347 and arc 1349 that communicate each other, and square hole 1347 is close to draw-in groove 1341 relative to arc 1349. The width of the square hole 1347 is smaller than the outer diameter of the rotating member 111, and the diameter of the arc hole 1349 is larger than the outer diameter of the rotating member 111.

Fig. 8 is a schematic structural diagram of the rotating member 111 of the dual-lock linkage mechanism 100 according to an embodiment of the present invention, please refer to fig. 8 in combination with fig. 2. The two sides of the rotating member 111 close to the limiting plate 134 are provided with first notches 1111. The rotating member 111 may be inserted into the arc hole 1349 of the stopper plate 134 and may rotate in the arc hole 1349. The rotating member 111 can be clamped into the square hole 1347 of the limiting plate 134 through the first notch 1111, and after the rotating member 111 is clamped into the square hole 1347, two side walls of the square hole 1347 clamp the square rod 1110 fixed in the rotating member 111, the square rod 1110 cannot rotate, and accordingly, the rotating member 111, the first connecting member 112, the first handle 113, and the second handle 114 cannot rotate.

In the state shown in fig. 2, the rotating member 111 is located in the arc hole 1349 of the stopper plate 134, and the rotating member 111 can rotate in the arc hole 1349. When the safety handle 131 is rotated clockwise, the rotating block 133 is driven to rotate, the rotating block 133 pushes the limiting plate 134 to move, so that the square hole 1347 of the limiting plate 134 is close to the rotating member 111, and finally the first notch 1111 of the rotating member 111 is clamped into the square hole 1347. The rotation member 111 cannot be rotated after being inserted into the square hole 1347. During the movement of the position limiting plate 134, the positioning groove 1161 plays a role in guiding and positioning, so that the rotation of the safety handle 131 is converted into the linear motion of the position limiting plate 134.

Preferably, a reset tension spring 135 is fixedly disposed on one side of the limiting plate 134, and in this embodiment, a first pin (not shown in the figure) is fixedly disposed on one side of the limiting plate 134 close to the second limiting block 116, the first pin is fixedly connected to one end of the reset tension spring 135, and the other end of the reset tension spring 135 is fixedly connected to the second limiting block 116 through a second pin 136.

Fig. 9 is a schematic structural diagram of a rotating block 133 of the dual-lock linkage mechanism 100 according to an embodiment of the present invention, please refer to fig. 9 in combination with fig. 2 and fig. 5. The rotating block 133 includes a first end surface 1331 and a second end surface 1333, and the first end surface 1331 and the second end surface 1333 are connected by a rounded transition.

When the safety handle 131 rotates clockwise, the stopper plate 134 moves, the square hole 1347 approaches the rotating member 111, the square shaft 1110 in the rotating member 111 is caught, and the return tension spring 135 is pulled. At this time, the first end 1331 (straight end surface) of the rotating block 133 is in close contact with the bottom 13411 (the side close to the square hole 1347) of the slot 1341, and the rotating block 133 does not rotate under the action of the return tension spring 135, so that the square hole 1347 can clamp the square rod 1110 more stably. The locking of the rotating member 111 by the square hole 1347 can be released only by applying an external force to the safety handle 131 to rotate it counterclockwise.

When the safety handle 131 rotates counterclockwise to release the square bar 1110 from being held by the square hole 1347, the rotating block 133 rotates along with the safety handle until the second end 1333 of the rotating block 133 abuts against the protrusion 1345 of the slot 1341, the square hole 1347 is completely separated from the rotating member 111, the protrusion 1345 restricts the rotating block 133 from continuing to rotate, and at the same time, restricts the square hole 1347 of the position limiting plate 134 from continuing to be away from the rotating member 111. Under the restoring force of the return tension spring 135, the square hole 1347 is kept away from the rotating member 111, so as to avoid the square hole 1347 from restricting the rotation of the rotating member 111 due to vibration or other factors. The reset spring 135 ensures that the square hole 1347 is completely separated from the square shaft 1110 when the arming state is released.

It should be noted that the position of the first notch 1111 corresponds to the position of the square hole 1347, when the first handle 113 starts to unlock from the initial position and rotate, the square rod 1110 and the rotating member 111 are driven to rotate, and the first notch 1111 rotates along with the first handle, so that the square hole 1347 can no longer hold the rotating member 111. Namely, the safety action is disabled after the handle is turned, which is to prevent the square bar 1110 from being forcibly turned by 90 degrees and then being blocked by the square hole 1347 on the other two sides of the square bar 1110, i.e. prevent the double lock from being closed due to the malicious handle being blocked at the unlocking limit position.

Preferably, the vehicle according to the present invention includes the above-described double lock link mechanism 100, and the key cylinder 161 is mounted on the vehicle body, and the locking teeth 162, the locking block 163, the unlocking member 170, the link mechanism 110, and the securing structure 130 are mounted on the door. The double-lock linkage mechanism 100 is used for opening or closing the door of the vehicle, so that the door is locked more safely and firmly, and the door is opened more quickly and conveniently. The safety performance of the vehicle is improved, the operation and the control are convenient, and the human-computer environment effect is good. The dual lock linkage 100 is suitable for use in various types of vehicles, such as domestic, off-road, armored or other specialty equipment.

The working principle of the double-lock linkage mechanism 100 and the vehicle provided by the invention is as follows:

the first locking tooth 164 and the second locking tooth 165 of the two locksets 150 respectively lock the lock cylinder 161, the locking block 163 is clamped with the first locking tooth 164 and the second locking tooth 165, and the two locksets 150 are both in a closed state.

The handle on either side is turned to effect simultaneous unlocking of both locks 150. If the first handle 113 is rotated, the first connecting member 112 simultaneously drives the transmission members 117 on the left and right sides of the rotating member 111 to move, the transmission members 117 drive the second connecting member 118 to move, the second connecting member 118 drives the rotating rod 171 to rotate, the cylindrical pin 173 on the rotating rod 171 rotates in the sliding slot 1741 to drive the shifting block 174 to move, the shifting block 174 disengages the locking block 163 from the engagement between the first locking tooth 164 and the second locking tooth 165, and the first locking tooth 164 and the second locking tooth 165 rotate under the restoring force of the spring 166, so that the first opening 1641 and the second opening 1651 are away from each other, and the lock cylinder 161 is released to be unlocked.

The first handle 113 rotates by about 90 degrees and is blocked by the first limiting block 115 and the second limiting block 116, and the handle only needs to rotate within a range less than or equal to 90 degrees, so that the two locksets 150 can be unlocked simultaneously.

The safety structure 130 is used for limiting the rotation of the first handle 113 and the second handle 114, the safety handle 131 is rotated to drive the rotation shaft 132 to rotate, the rotation block 133 on the rotation shaft 132 pushes the limiting plate 134 to move, the square hole 1347 of the limiting plate 134 moves to the first notch 1111 of the rotation member 111, and the square rod 1110 is clamped to limit the rotation of the rotation member 111. That is, neither the first handle 113 nor the second handle 114 can rotate, and the two locksets 150 cannot be unlocked. When the safety handle 131 is rotated reversely again, the rotation restriction of the safety handle 131 on the square shaft 1110 of the rotating member 111 is released, the first handle 113 and the second handle 114 can be rotated, and the lock 150 can be unlocked.

It should be noted that, in the double-lock linkage mechanism 100, the force required for toggling the safety handle 131 is small, and the double-lock linkage mechanism can be conveniently directly driven by a micro electric mechanism with small push-pull force or torque, or even a micro motor, so as to conveniently realize the safety locking and unlocking of a plurality of door locks. Generally, the micro push-pull electric mechanism and the micro motor are easy to be forced to move reversely or rotate reversely manually, so that the manual override central control is simply realized to carry out reverse insurance or insurance relief.

In summary, the double-lock linkage mechanism 100 and the vehicle provided by the invention have the following beneficial effects:

according to the double-lock linkage mechanism 100 and the vehicle comprising the double-lock linkage mechanism 100, firstly, the two locksets 150 are connected through the transmission piece 117 of the linkage structure 110, and the two transmission pieces 117 can be driven to move by rotating the rotating piece 111, so that the two locksets 150 can be unlocked simultaneously. Secondly, by respectively arranging the first handle 113 and the second handle 114 at two ends of the rotating member 111, the first handle 113 or the second handle 114 can be rotated at any side of the dual-lock linkage mechanism 100, so as to unlock the two locksets 150. Then, the locking block 163 is provided with an emergency unlocking notch 1632, so that the lock 150 can be unlocked in an emergency or in a state where the linkage structure 110 and the unlocking assembly 170 are failed, and the safety performance is higher. Finally, the safety handle 131 of the safety structure 130 rotates to drive the limiting plate 134 to move, so that the square hole 1347 of the limiting plate 134 blocks the square rod 1110, thereby limiting the rotation of the rotating member 111 and simultaneously locking the two locks 150. The double-lock linkage mechanism 100 is convenient to operate and control with a vehicle, is reliable in structure, and has great popularization and application values.
