Description

Technical Field

[0001] The utility model relates to a lock, in particular to an electric suction door lock used on a vehicle. Background Art

[0002] With the advancement of intelligent technology of automobile products, electric suction door lock devices have appeared in high-end brands or new brands of automobile door systems. This device only requires people to pull the car door to the predetermined position, and the door lock can automatically lock the door under the drive of the electric device. It has changed the traditional operation mode that requires the operator to use acceleration to pull the door to lock the door, effectively avoiding the trouble of repeatedly closing the door or violently closing the door due to insufficient force, and is favored by consumers. However, because this function is only equipped on high-end brands, the price is high and cannot meet the needs of ordinary consumers. In recent years, some economical and practical external self-suction door lock devices have been launched on the market. This type of external self-suction door lock device adds an auxiliary electric drive device to realize the function of automatic locking of the door lock without changing the original car door lock structure. Although the electric suction door lock function is realized, if the motor drive device of this structure fails during the locking process, it will directly lead to the inability to open the door, and the door panel needs to be destroyed to release it. In addition, during the driving locking process, if the hand is pinched, the locking process cannot be interrupted, which may cause personal injury. Therefore, improvement is needed.

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, the electric suction door lock device in this embodiment is arranged on the vehicle door, and specifically includes a mounting plate 1, a lock tongue 2, a first swing arm 3, a second swing arm 4, a pull wire 5, a first reset member 81, a micro switch 7, a second reset member 82, a third reset member 83 and a pull cable 6.

[0029] The mounting plate 1 has a first lock port 11 for the lock bolt 10 to be placed in. The mounting plate 1 is provided with a limit column 12 for limiting the swing amplitude of the second swing arm 4. The mounting plate 1 has a mounting hole fixed to the vehicle lock.

[0030] The lock tongue 2 is rotatably mounted on the mounting plate 1 via a first shaft 91. One end of the lock tongue 2 has a second lock opening 21 that cooperates with the first lock opening 11 to lock the latch 10, and the other end is formed with a first gear portion 23 and a second gear portion 24 adjacent to the first gear portion 23.

[0031] The first swing arm 3 is rotatably arranged on the mounting plate 1; Figure 3 As shown, the first swing arm 3 in this embodiment includes a first arm portion 31, a rotating portion 33 and a second arm portion 32 which is at an acute angle to the first arm portion 31 in the length direction, the rotating portion 33 is connected between the first arm portion 31 and the second arm portion 32, the rotating portion 33 is rotatably disposed on the mounting plate 1 through a second shaft 92, the pull wire 5 is connected to the first arm portion 31, and the second swing arm 4 is movably connected to the second arm portion 32.

[0032] The pull wire 5 can be externally connected to an electric driver 51, and is connected to the first end of the first swing arm 3; the mounting plate 1 is provided with a micro switch 7 that can be linked with the pull wire 5 near the first lock opening 11, the pull wire 5 is externally connected to the electric driver 51, and control signals are transmitted between the micro switch 7 and the electric driver 51. The lock tongue 2 is formed with a supporting portion 22 that can touch the micro switch 7 near the second lock opening 21.

[0033] One end of the second swing arm 4 is movably connected to the second end of the first swing arm 3 through the third shaft 93, and the other end can cooperate with the first gear part 23 and the second gear part 24 to realize the positioning of the lock tongue 2; when the second swing arm 4 acts on the lock tongue 2, the second swing arm 4 is against the limit column 12.

[0034] The first reset member 81 acts on the lock tongue 2 ; in this embodiment, the first reset member 81 is a first tension spring, one end of which is connected to the lock tongue 2 , and the other end of which is connected to the mounting plate 1 .

[0035] The second reset member 82 acts on the first swing arm 3 ; in this embodiment, the second reset member 82 is a second tension spring, one end of which is connected to the first arm portion 31 , and the other end of which is connected to the mounting plate 1 .

[0036] The third restoring member 83 acts on the second swing arm 4 ; the third restoring member 83 in this embodiment is a torsion spring arranged on the third shaft 93 .

[0037] The cable 6 can be connected to a door handle (including an inner opening handle and an outer opening handle), and one end is connected to the second swing arm 4. When the cable 6 is pulled, the other end of the second swing arm 4 can be separated from the lock tongue 2.

[0038] The first swing arm 3 includes a first arm portion 31, a rotating portion 33 and a second arm portion 32 which forms an acute angle with the first arm portion 31 in the length direction. The rotating portion 33 is connected between the first arm portion 31 and the second arm portion 32. The rotating portion 33 is rotatably disposed on the mounting plate 1 through a second shaft 92. The pull wire 5 is connected to the first arm portion 31, and the second swing arm 4 is movably connected to the second arm portion 32.

[0039] In this embodiment, the mounting hole on the mounting plate is fixed together with the original vehicle lock.

[0040] like Figure 4As shown, when the door lock moves toward the latch 10 along with the pulled vehicle door, the latch 10 hits and the lock tongue rotates, causing the pressed reed of the micro switch to reset, causing the signal to jump, triggering the motor in the electric drive to work forward, and the motor drives the pull wire to contract, and drives the first swing arm and the second swing arm to move, the first swing arm acts on the first gear portion of the lock tongue, forcing the lock tongue to continue to move in the direction of locking the door, because the mounting plate and the original vehicle lock are fixed to the vehicle door, at this time, the lock tongue drives the entire door to move in the direction of locking the door until it is locked to the second gear portion, and the original vehicle lock is synchronously locked to the second gear portion, realizing automatic door locking (such as Figure 5 shown).

[0041] When the door is locked to the second gear, the lock tongue disengages from the micro switch, the signal jumps, and the signal triggers the motor in the electric drive to reverse and drive the pull wire in the extension direction. Figure 1 The state of the door is maintained by the original car lock.

[0042] Figure 4 Enter Figure 5 During the process, pull the cable 6 to enter immediately Figure 1 The state (reset state) is the opening priority.

[0043] In case of emergency or failure or power failure of the electric drive, the user only needs to pull the inner or outer opening handle of the car connected to the cable to disengage the second swing arm from the working position, thereby interrupting the electric suction action of the lock tongue, and the lock tongue is reset under the action of the first reset member. Figure 6 As shown. This realizes the interruption of the electric suction or emergency release of the device. After the electric drive returns to normal and resets, the door lock can still work normally.
