Technical Field
[0001] This utility model relates to the field of door lock transmission technology, specifically to an electric suction door lock cylinder, an electric suction door lock, and an automobile. Background Technology
[0002] Electric door locks are widely used in various devices. For example, high-end cars use electric door locks in their door systems. These locks automatically lock the door when it is pulled to a predetermined position (e.g., the half-lock position). However, the high cost of electric door locks in high-end cars limits their application. Currently, some economical and practical external self-closing door locks have emerged on the market. These locks add an auxiliary electric drive device to achieve automatic locking without altering the original door lock structure. However, if the motor drive device malfunctions after the door is closed, the door cannot be opened, posing a safety hazard. Utility Model Content

[0007] After the detection device detects that the latch is in a half-locked state, it sends an electric suction signal to the drive device, which causes the drive device to drive the cable mechanism to move. The movement of the cable mechanism drives the suction mechanism to rotate, and the rotation of the suction mechanism pushes the latch to rotate, so that one end of the latch engages with the suction mechanism and the other end of the latch engages with one end of the locking mechanism to achieve a fully locked state.

[0009] After the other end of the unlocking mechanism is triggered by an external force to rotate, the unlocking mechanism rotates and pushes the engaging mechanism and the locking part, causing the engaging mechanism to separate from one end of the latch, and the locking mechanism to separate from the other end of the latch, thus unlocking.
[0010] In one alternative embodiment, a circuit board is provided on the side of the latch away from the faceplate. The input and output terminals of the circuit board are respectively input and output via PIN pins. The input terminal of the circuit board is electrically connected to the detection device, and the output terminal of the circuit board is electrically connected to the drive device.
[0011] In one alternative embodiment, a slot is recessed on the outer side of the output end of the circuit board, the pins of the output end of the circuit board are disposed in the slot, the pins of the output end of the circuit board and the slot form a male connector, and the input end of the drive device is provided as a female connector.
[0012] In one optional embodiment, the unlocking mechanism includes an unlocking lever, a clutch lever, and a rotating shaft. The locking mechanism is coaxially arranged with the unlocking lever and sandwiched between the unlocking lever and the face cover. The rotating shaft is located on the face cover and between the unlocking lever and the engaging mechanism. The middle part of the clutch lever is located on the rotating shaft.

One end of the unlocking lever is located between the locking part and the limiting block and is connected to one end of the clutch lever. The other end of the clutch lever is connected to the middle part of the engaging mechanism.
[0014] When the other end of the unlock lever is triggered by an external force to rotate, the unlock lever rotates and pushes one end of the clutch lever and the locking part. The other end of the clutch lever rotates and pushes the engaging mechanism to rotate, so that the engaging mechanism separates from one end of the latch, and one end of the locking mechanism separates from the other end of the latch to unlock.
[0015] In one alternative embodiment, the suction mechanism includes a suction push rod, one end of which is connected to the cable mechanism and the other end is provided with a first engaging portion, and one end of the locking tongue is provided with a first locking block.

[0023] In this embodiment, the electric suction door lock cylinder has a cable mechanism, a suction mechanism, an unlocking mechanism, and a locking mechanism arranged on the same side as the cover. When the detection device detects that the bolt is in a half-locked state, it sends an electric suction signal to the drive device. The drive device drives the cable mechanism to move, which in turn drives the suction mechanism to rotate. The rotation of the suction mechanism pushes the bolt to rotate in the locking direction. After the bolt rotates, one end of the bolt engages with the suction mechanism, and the other end engages with one end of the locking mechanism, achieving a fully locked state. When the other end of the unlocking mechanism is triggered by external force, the unlocking mechanism rotates and pushes the suction mechanism and the locking part, causing the suction mechanism to separate from one end of the bolt, and the locking mechanism to separate from the other end of the bolt, thus unlocking the lock cylinder. Even if the drive device malfunctions and cannot be unlocked by the drive device, the unlocking mechanism can still be triggered by external force to unlock the lock, ensuring high security.

[0035] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.
[0036] Please see Figures 1-2The electric suction door lock cylinder 100 includes a detection device (not shown in the figure), a drive device (not shown in the figure), a cover 1, a pull cable mechanism 2 located on the same side of the cover 1, a suction mechanism 3, an unlocking mechanism 4, a locking mechanism 5, and a bolt 6. The detection device is electrically connected to the drive device, and the drive device drives the pull cable mechanism 2.
[0037] The detection device is positioned near the latch 6 and is used to detect the state of the latch 6, such as whether it is in a partially locked state. The detection device can be a Hall sensor, or a camera or other device capable of detecting the state of the latch 6; no limitation is made here. Figure 3 As shown, the locking tongue 6 remains in a half-locked state. After the detection device detects that the locking tongue 6 is in a half-locked state, it sends an electric suction signal to the drive device. The drive device can be an electric motor, which can convert electrical energy into mechanical energy to drive the cable mechanism 2 to move according to the electric suction signal.
[0038] The suction mechanism 3, unlocking mechanism 4, locking mechanism 5, and latch 6 are rotatably mounted on the cover 1. The cable mechanism 2 is driven by the suction mechanism 3, and the suction mechanism 3 is driven by the latch 6. After the detection device detects that the latch 6 is in a half-locked state, it sends an electric suction signal to the drive device, causing the drive device to drive the cable mechanism 2 to move. The movement of the cable mechanism 2 drives the suction mechanism 3 to rotate. When the suction mechanism 3 rotates, it pushes the latch 6, which is in a half-locked state, to rotate in the locking direction. After the latch 6 rotates, one end of the latch 6 engages with the suction mechanism 3, and the other end of the latch 6 engages with one end of the locking mechanism 5. After engagement, the lock cylinder 100 automatically electrically engages from a half-locked state to a fully locked state. After the lock cylinder 100 reaches the fully locked state, the detection device detects that the latch 6 is in a fully locked state and sends a return signal to the drive device. The drive device drives the cable mechanism 2 to return to its initial position according to the return signal, causing the lock cylinder 100 to lock.
[0039] The locking mechanism 5 has a locking part 51 at one end, and the unlocking mechanism 4 is located between the locking part 51 and the locking tongue 6. The unlocking mechanism 4 is also connected to the middle part of the suction mechanism 3 via a transmission connection.
[0040] In the event that the drive mechanism of the electric suction door lock malfunctions and cannot be unlocked by the drive mechanism, the other end of the unlocking mechanism 4 can be triggered by external force. After the other end of the unlocking mechanism 4 is triggered, the unlocking mechanism 4 rotates in the unlocking direction. The rotation of the unlocking mechanism 4 in the unlocking direction pushes the suction mechanism 3 and the locking part 51. The rotation of the suction mechanism 3 causes the suction mechanism 3 to separate from one end of the lock tongue 6, and the movement of the locking part 51 drives the locking mechanism 5 to rotate. After the locking mechanism 5 rotates, one end of it separates from the other end of the lock tongue 6, and the lock cylinder 100 is unlocked.
[0041] In this embodiment, the electric suction door lock cylinder 100 has a cable mechanism 2, a suction mechanism 3, an unlocking mechanism 4, and a locking mechanism 5 arranged on the same side as the cover 1. When the detection device detects that the bolt 6 is in a half-locked state, it sends an electric suction signal to the drive device. The drive device drives the cable mechanism 2 to move, which in turn drives the suction mechanism 3 to rotate. The rotation of the suction mechanism 3 pushes the bolt 6 to rotate in the locking direction. After the bolt 6 rotates, one end of the bolt 6 engages with the suction mechanism 3, and the other end of the bolt 6 engages with one end of the locking mechanism 5, achieving a fully locked state. When the other end of the unlocking mechanism 4 is triggered by external force, the unlocking mechanism 4 rotates and pushes the suction mechanism 3 and the locking stop part 51, causing the suction mechanism 3 to separate from one end of the bolt 6. After the locking mechanism 5 rotates, one end of it separates from the other end of the bolt 6, and the lock cylinder 100 is unlocked. Even if the drive device fails and cannot be unlocked by the drive device, the unlocking mechanism 4 can still be triggered by external force to unlock the door, thus ensuring high security.
[0042] Furthermore, in conjunction with reference Figure 2 and Figure 4 A circuit board 7 is also provided on the side of the locking tongue 6 away from the face cover 1. The input end and output end of the circuit board 7 are respectively input and output through PIN pin 71. The input end of the circuit board 7 is electrically connected to the detection device, and the output end of the circuit board 7 is electrically connected to the drive device.
[0043] The detection device detects the position of the bolt 6 and sends the position signal of the bolt 6 to the circuit board 7. The circuit board 7 processes the position signal and ultimately becomes the drive signal for the drive device. In existing lock cylinders, due to space limitations, two circuit boards are often set up and connected by wires. The input and output ends of the circuit boards are also transmitted by soldering wires, which makes the lock cylinder wiring complex and the soldering method can easily cause the wires to break from the circuit board. In this embodiment, a circuit board 7 is set on the side of the bolt 6 away from the cover 1, avoiding the wiring between the circuit boards. The input and output ends of the circuit board 7 are respectively input and output through PIN pins 71, where the input end is located on the circuit board 7 and the output end is the end of the PIN pin 71 away from the circuit board. Avoiding the soldering of wires prevents the problem of wire breakage and makes the performance more stable. Preferably, the PIN pin 71 is made of copper to ensure better stability and conductivity.
[0044] Furthermore, such as Figure 4 As shown, a slot 8 is recessed on the outer side of the output end of the circuit board 7. The PIN pin 71 of the output end of the circuit board 7 is located in the slot 8, forming a male connector with the slot 8. The input end of the drive device is a female connector. During wiring, the input end of the drive device, which serves as the female connector, can be directly inserted into the slot 8 of the male connector to achieve electrical connection between the detection device and the drive device. The connection is convenient and the operation is easy.
[0045] Furthermore, in conjunction with reference Figure 5 and Figure 6 The unlocking mechanism 4 includes an unlocking lever 41, a clutch lever 42, and a rotating shaft 43. The locking mechanism 5 is coaxially arranged with the unlocking lever 41 and clamped between the unlocking lever 41 and the cover 1. The unlocking lever 41 can rotate around the axis of the locking mechanism 5. The rotating shaft 43 is located on the cover 1 and between the unlocking lever 41 and the engaging mechanism 3. The middle part of the clutch lever 42 is located on the rotating shaft 43, and the clutch lever 42 can rotate around the rotating shaft 43.
[0046] A limiting block 61 is provided at one end of the locking tongue 6 corresponding to the unlocking lever 41. One end of the unlocking lever 41 is located between the locking part 51 and the limiting block 61, and is operatively connected to one end of the clutch lever 42. The limiting block 61 and the locking part 51 restrict the rotation range of one end of the unlocking lever 41. The other end of the clutch lever 42 is operatively connected to the middle of the engaging mechanism 3. When the other end of the unlocking lever 41 is triggered by external force to rotate in the unlocking direction, the unlocking lever 41 rotates in the unlocking direction, pushing one end of the clutch lever 42 and the locking part 51. The rotation of the other end of the clutch lever 42 pushes the engaging mechanism 3 to rotate. The rotation of the engaging mechanism 3 causes the engaging mechanism 3 to separate from one end of the locking tongue 6, and the locking part 51 drives one end of the locking mechanism 5 to rotate, causing one end of the locking mechanism 5 to separate from the other end of the locking tongue 6 and unlock.
[0047] In this embodiment, the transmission between the unlocking lever 41, the clutch lever 42 and the engaging mechanism 3 enables the engaging mechanism 3 to separate from one end of the locking tongue 6. The unlocking lever 41 pushes the locking part 51, thereby separating one end of the locking mechanism 5 from the other end of the locking tongue 6. Thus, the unlocking lever 41 can be triggered by external force to unlock the device.
[0048] Furthermore, such as Figure 5 As shown, the suction mechanism 3 includes a suction push rod 31 and a push rod shaft. The suction push rod 31 is mounted on the push rod shaft and can rotate around it. One end of the suction push rod 31 is connected to the cable mechanism 2, and the other end is provided with a first engaging part 311. One end of the locking tongue 6 is provided with a first locking block 62. The shaft of the locking tongue 6 is located in the middle of the locking tongue 6. In order to make the suction push rod 31 push the locking tongue 6 more effortlessly and accurately, the other end of the suction push rod 31 is bent towards one side of the locking tongue 6. The other end of the suction push rod 31 is bent and close to the locking tongue 6, which matches the arc trajectory of the locking tongue 6's rotation, thus enabling better pushing of the locking tongue 6.
[0049] like Figure 6As shown, the locking mechanism 5 includes a locking rod 52. One end of the locking rod 52 has a locking part near the unlocking lever 41, and the other end of the locking rod 52 has a second engaging part 521 near the bolt 6. The other end of the bolt 6 has a protruding second locking block 63. When the bolt 6 is rotated by the pull-in lever 31, the first locking block 62 engages with the first engaging part 311, and the second locking block 63 engages with the second engaging part 521, thus the lock cylinder 100 is fully locked. When the clutch lever 42 pushes the pull-in lever 31 to rotate, causing the first locking block 62 to separate from the first engaging part 311, and the unlocking lever 41 pushes the locking rod 52 to rotate, causing the second locking block 63 to separate from the second engaging part 521, the lock cylinder 100 is unlocked.
[0050] Furthermore, the cover 1 is also provided with a limiting post 9 at one end of the clutch lever 42. One end of the clutch lever 42 is located between one end of the unlocking lever 41 and the limiting post 9. Thus, when one end of the unlocking lever 41 pushes one end of the clutch lever 42, the rotation range of the clutch lever 42 is limited by one end of the unlocking lever 41 and the limiting post 9. It can only rotate between one end of the unlocking lever 41 and the limiting post 9, so that the other end of the clutch lever 42 just pushes the suction push rod 31. The suction push rod 31 can be better separated from the locking tongue 6 without pushing the suction push rod 31 further, so that it can return to its original position better after unlocking.
[0051] Furthermore, the cable mechanism 2 includes a drive cable 21 and a cable lever 22. The cable lever 22 is mounted on the cover 1 via a lever shaft. The drive device drives the drive cable 21, which in turn drives the cable lever 22. The cable lever 22 then drives the engagement push rod 31. Under the action of the drive device, the drive cable 21 is pulled, and the drive cable 21 drives the cable lever 22 via a lever principle, thereby causing the cable lever 22 to move and thus driving the engagement push rod 31 to rotate.
[0052] This utility model also provides an electric suction door lock, such as Figure 7 As shown, the electric door lock includes a central locking system 200 and a lock cylinder 100 as described above. The input end of the central locking system 200 is connected to the door switch, and the output end of the central locking system 200 is connected to the other end of the unlocking mechanism 4. When the door switch is operated, the central locking system 200 triggers the other end of the unlocking mechanism 4, causing the lock cylinder 100 to unlock. If the lock cylinder 100 of the electric door lock malfunctions or is damaged, it can be directly replaced. The signal control and functional parts of the central locking system 200 can be completely retained and do not need to be replaced.
[0053] This utility model also provides a car that includes the electric suction door lock described above.
