Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to a signal triggering mechanism, a vehicle lock and a vehicle. Background Art

[0002] As a vehicle safety feature, it is crucial to accurately identify whether the vehicle lock is fully locked during use. Existing vehicle locks are usually equipped with a micro switch, and the locking status of the vehicle lock is determined by the on and off of the micro switch.

[0003] like Figure 5 As shown, existing vehicle locks typically include a lock pin 14, a base plate 11, a ratchet 12, a pawl 13, a first riveted shaft, a second riveted shaft, and a microswitch 16. The ratchet 12 is rotatably mounted on the base plate 11 via the first riveted shaft, the pawl 13 is rotatably mounted on the base plate 11 via the second riveted shaft, and the microswitch 16 is mounted on the base plate 11. The ratchet 12 is provided with a switch trigger 15 and a locking groove for engaging with the lock pin. During the locking process of the vehicle lock, the lock pin 14 strikes the ratchet 12, driving the ratchet 12 to rotate around the first riveted shaft. During the rotation of the ratchet 12, the ratchet 12 and the pawl 13 engage in a half-locked position and a fully locked position, respectively. When the ratchet 12 and the pawl 13 engage in the fully locked position, the switch trigger 15 on the ratchet 12 cooperates with the microswitch 16 to close or release the microswitch 16, triggering the microswitch 16 to feedback a locking signal.

[0004] Although the locking state of the vehicle lock can be determined by the on and off of the micro switch, this vehicle lock has the following technical problems: There's typically an advance angle between the microswitch and the switch trigger. This advance angle means that when the ratchet and pawl are in contact at the fully locked position but haven't reached the designed engagement length, the switch trigger has already triggered the microswitch, at which point the microswitch will respond with a switch signal. When the ratchet and pawl are in contact at the fully locked position but haven't reached the designed engagement length, the vehicle lock is in a partially locked state, but the microswitch has already transmitted the locking signal to the vehicle control center and the driver. At this point, the vehicle can still start and drive normally. However, if the vehicle encounters bumps or vibrations while driving, the incompletely engaged ratchet and pawl may separate, causing the vehicle lock to unlock, posing a significant safety risk to the driver and passengers.

[0005] The components involved in the switch signal output in existing vehicle locks have a long kinematic dimension chain. Key components include the ratchet, pawl, first and second riveted shafts, microswitch, and baseplate. To ensure proper operation, these key components must meet very strict dimensional tolerances, which cannot be completely eliminated. Neither can the lead angle between the microswitch and the switch trigger. Therefore, the aforementioned false lock problem is difficult to directly eliminate.

[0006] To avoid the problem of false locking, some vehicle locks also have a micro switch installed at the pawl. The switch signals of the two micro switches simultaneously determine the position of the ratchet and pawl. The signal is output only when the two switch signals simultaneously meet the judgment conditions. Although this can avoid the false locking problem, it will lead to stricter requirements for the size chain of the internal components of the vehicle lock. At the same time, it will increase the number of internal components of the vehicle lock, increase the number of vehicle lock-related circuits, increase the size and weight of the vehicle lock, make the vehicle lock control logic more complex, and increase the cost of the entire vehicle.

[0007] Moreover, the above-mentioned vehicle locks all rely on micro switches to feedback locking and unlocking signals. Vehicle locks are one of the frequently used components on vehicles. Therefore, the durability and reliability of the micro switches are required to be high, and the quality of the micro switches is required to be high, resulting in a high cost of the micro switches. Summary of the Invention

DETAILED DESCRIPTION

[0022] The following describes the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art will readily appreciate the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the various details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0023] It should be noted that the illustrations provided in the following embodiments are merely schematic illustrations of the basic concept of the present invention. The illustrations only show components related to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component may be changed arbitrarily, and the component layout may also be more complex.

[0024] like Figures 1 to 4A signal trigger mechanism is shown, which is suitable for a vehicle lock. The signal trigger mechanism includes a base 1, a ratchet 2 and a pawl 3 of the vehicle lock. The ratchet 2 and the pawl 3 are both rotatably mounted on the base 1. The ratchet 2 is provided with a first meshing surface 207, and an exposed first conductive portion 208 is provided at the first meshing surface 207. The pawl 3 is provided with a second meshing surface 305, and an exposed second conductive portion 306 is provided at the second meshing surface 305. The first conductive portion 208 and the second conductive portion 306 constitute a signal switch; when the first meshing surface 207 is meshed with the second meshing surface 305, the vehicle lock is in a locked state, and the first conductive portion 208 contacts the second conductive portion 306 to turn on the signal switch; when the first meshing surface 207 is separated from the second meshing surface 305, the vehicle lock is in an unlocked state, and the first conductive portion 208 is separated from the second conductive portion 306 to turn off the signal switch.

[0025] By adopting the above-mentioned technical solution, the first conductive portion 208 on the ratchet 2 and the second conductive portion 306 on the pawl 3 are used to form a signal switch. The conduction and disconnection of the signal switch are directly related to the contact and separation between the first meshing surface 207 and the second meshing surface 305. This can reduce or even eliminate the advance angle of the signal switch, so that the signal trigger mechanism can output the unlocking and locking signals of the vehicle lock in real time. The above-mentioned signal switch can replace the micro switch in the prior art, and the reliability of the signal switch is higher. The motion dimension chain of the signal trigger mechanism is shorter, the requirements for the size of the components are lower, and it is easier to implement. The signal trigger mechanism has the characteristics of a small number of components, a simple internal circuit, a small size, a light weight and a low cost, which helps to reduce the vehicle body wiring harness interface and helps to simplify the control logic of the vehicle lock.

[0026] It should be noted that, generally, the states of the vehicle lock include a fully locked state, a half-locked state and an unlocked state. The above-mentioned locking state is the fully locked state, and the first meshing surface 207 is the fully locked limiting surface of the ratchet 2 .

[0027] As a specific example, a semi-locked limiting surface is further provided on the ratchet 2. When the semi-locked limiting surface is engaged with the second engaging surface 305, the vehicle lock is in a semi-locked state.

[0028] In a specific embodiment, the ratchet 2 is further provided with a locking groove 203 for engaging with a locking pin 6 on a vehicle component. The ratchet 2 is provided with a first meshing portion 204 and a third meshing portion 205, respectively located on either side of the locking groove 203. A first meshing surface 207 is provided on the first meshing portion 204, and a semi-locking limiting surface is provided on the third meshing portion 205. A second meshing portion 304 is provided on the side of the pawl 3 closest to the ratchet 2, and a second meshing surface 305 is provided on the second meshing portion 304.

[0029] In some embodiments, the ratchet 2 is provided with an exposed third conductive portion 206, which is electrically conductive with the first conductive portion 208. The signal triggering mechanism further includes a first conductive spring 7 in contact with the third conductive portion 206. The third conductive portion 206 and the first conductive spring 7 can maintain contact during the rotation of the ratchet 2. The first conductive spring 7 is pressed against the third conductive portion 206 to maintain electrical conduction between the first conductive spring 7 and the third conductive portion 206. The first conductive spring 7 is used to connect to the wiring harness of the vehicle lock control circuit to continuously connect the signal switch to the vehicle lock control circuit.

[0030] In some embodiments, the ratchet 2 includes a ratchet body 201 and a ratchet overmolding layer 202 covering the outside of the ratchet body 201. The ratchet body 201 is a conductor, and the first conductive portion 208 and the third conductive portion 206 are both disposed on the ratchet body 201. The ratchet overmolding layer 202 is provided with a first notch for exposing the first conductive portion 208 and a second notch for exposing the third conductive portion 206. The provision of the ratchet overmolding layer 202 can reduce friction between the ratchet 2 and the pawl 3, reduce wear between the ratchet 2 and the pawl 3, and reduce or even eliminate abnormal noise between the ratchet 2 and the pawl 3. Furthermore, the ratchet overmolding layer 202 can also act as an insulator. After the first conductive portion 208 and the second conductive portion 306 are separated, the ratchet overmolding layer 202 can form an insulating barrier between the ratchet body 201 and the pawl 3.

[0031] In some embodiments, the outer surface of the first conductive portion 208 is flush with the outer surface of the ratchet overmolded layer 202 at the first meshing surface 207. A portion of the ratchet overmolded layer 202 is disposed at the first meshing surface 207, and the outer surface of the first conductive portion 208 is flush with the outer surface of the ratchet overmolded layer 202 at the first meshing surface 207, allowing the first conductive portion 208 to more smoothly contact the second conductive portion 306.

[0032] In a specific implementation, a first notch is provided in the straight section of the first meshing surface 207 of the ratchet overmolding layer 202. The ratchet body 201 is exposed at the first notch to form a first conductive portion 208. The outer surface of the first conductive portion 208 is flush with the straight section of the first meshing surface 207. A second notch extending along the circumferential direction is provided in the ratchet overmolding layer 202 around the root of the ratchet 2. The ratchet body 201 is exposed at the second notch to form a third conductive portion 206. The circumferential length of the third conductive portion 206 is set to ensure that the ratchet 2 always maintains contact with the first conductive spring 7 during the rotation and locking process. Figure 4 It can be seen from the first motion envelope 9 in FIG. 1 that, as long as the circumferential length of the third conductive portion 206 is set to be long enough, the third conductive portion 206 and the first conductive reed 7 can maintain contact during the rotation of the ratchet 2 .

[0033] In some embodiments, the pawl 3 is provided with an exposed fourth conductive portion 303, which is electrically conductive with the second conductive portion 306. The signal triggering mechanism further includes a second conductive spring 8 in contact with the fourth conductive portion 303. The fourth conductive portion 303 and the second conductive spring 8 can maintain contact during the rotation of the pawl 3. The second conductive spring 8 is pressed against the fourth conductive portion 303 to maintain electrical conduction between the second conductive spring 8 and the fourth conductive portion 303. The second conductive spring 8 is used to connect to the wiring harness of the vehicle lock control circuit to continuously connect the signal switch to the vehicle lock control circuit.

[0034] In some embodiments, the pawl 3 includes a pawl body 301 and a pawl overmolding layer 302 covering the outside of the pawl body 301. The pawl body 301 is a conductor, and the second conductive portion 306 and the fourth conductive portion 303 are both disposed on the pawl body 301. The pawl overmolding layer 302 is provided with a third notch for exposing the second conductive portion 306 and a fourth notch for exposing the fourth conductive portion 303. The provision of the pawl overmolding layer 302 can reduce friction between the ratchet 2 and the pawl 3, reduce wear between the ratchet 2 and the pawl 3, and reduce or even eliminate abnormal noise between the ratchet 2 and the pawl 3. Furthermore, the pawl overmolding layer 302 can also act as an insulator. After the first conductive portion 208 and the second conductive portion 306 are separated, the pawl overmolding layer 302 can form an insulating barrier between the ratchet body 201 and the pawl body 301.

[0035] In some embodiments, the outer surface of the second conductive portion 306 is flush with the outer surface of the pawl overmolded layer 302 at the second mating surface 305. A portion of the pawl overmolded layer 302 is disposed at the second mating surface 305, and the outer surface of the second conductive portion 306 is flush with the outer surface of the pawl overmolded layer 302 at the second mating surface 305, allowing the second conductive portion 306 to more smoothly contact the first conductive portion 208.

[0036] In a specific implementation, a third notch is provided at the second meshing surface 305 of the pawl overmolded layer 302, and the pawl body 301 protruding from the third notch is exposed to form a second conductive portion 306. The outer surface of the second conductive portion 306 is flush with the second meshing surface 305, and there is a gap between the starting position of the second conductive portion 306 and the corner portion 307 outside the second meshing surface 305. The gap length is L, and L is not less than the effective meshing length required for the ratchet 2 and the pawl 3 to achieve full lock.

[0037] A fourth notch extending in the circumferential direction is provided on the pawl plastic coating 302 on the circumferential side of the root of the pawl 3. The pawl body 301 at the fourth notch is exposed to form a fourth conductive portion 303. The circumferential length of the fourth conductive portion 303 is set to ensure that the pawl 3 always maintains contact with the second conductive spring 8 during the process of rotation and locking. Figure 4It can be seen from the second motion envelope 10 in FIG. 1 that, as long as the circumferential length of the fourth conductive portion 303 is set long enough, the fourth conductive portion 303 and the second conductive spring 8 can maintain contact during the rotation of the pawl 3 .

[0038] In specific implementation, the second meshing surface 305 is the stop surface on the pawl 3. The second meshing surface 305 can respectively engage with the half-lock limiting surface and the full-lock limiting surface of the ratchet 2 to prevent the ratchet 2 from rotating in the opposite direction, thereby realizing the first-level locking and full locking of the vehicle lock.

[0039] In some embodiments, there is a gap between the first conductive portion 208 and the end of the first meshing surface 207 away from the pawl 3, and / or there is a gap between the second conductive portion 306 and the end of the second meshing surface 305 away from the pawl 3. In a specific implementation, the gap distance is L, and L is not less than the effective meshing length required for the ratchet 2 and the pawl 3 to achieve full lock. The above technical solution can prevent the first conductive portion 208 and the second conductive portion 306 from being released when the first meshing surface 207 and the second meshing surface 305 are not fully engaged, and prevent the signal switch from sending a switch signal indicating locking when the vehicle lock is in a virtual lock state, so that the signal trigger mechanism can output the vehicle lock unlocking and locking signals in real time.

[0040] Using the aforementioned signal trigger mechanism, the first and second conductive springs 7 and 8 are connected to the vehicle lock control circuit to output locking and unlocking signals. When the ratchet 2 rotates about the first shaft 4 to the fully locked position, the second meshing surface 305 of the pawl 3 engages with the first meshing surface 207 of the ratchet 2. At this point, the second conductive portion 306 of the pawl 3 contacts the first conductive portion 208 of the ratchet 2, completing a current conduction loop and providing feedback signaling that the lock is complete.

[0041] The working principle of the aforementioned signal trigger mechanism will be explained using a vehicle lock applied to a vehicle door as an example. During the door closing process, the lock pin 6 on the door strikes the ratchet 2 and engages the locking slot 203. The ratchet 2 rotates counterclockwise around the first rotating shaft 4 and pushes the pawl 3 to rotate clockwise around the second rotating shaft 5 until the vehicle lock is fully locked. During this process, the first conductive spring 7 is always in contact with the third conductive portion 206 of the ratchet 2, and the second conductive spring 8 is always in contact with the fourth conductive portion 303 of the pawl 3. When the ratchet 2 approaches the fully locked position, the first meshing surface 207 begins to contact the second meshing surface 305. The ratchet 2 continues to rotate until the first meshing surface 207 and the second meshing surface 305 reach the effective meshing length. The first conductive portion 208 contacts the second conductive portion 306, and the signal switch turns on, outputting a door locking signal.

[0042] Compared with the signal triggering scheme of existing vehicle locks, the advantage of the signal triggering mechanism provided by the present invention is that the conduction of the vehicle lock control circuit is completely realized by the contact of the conductive material, and the locking signal is output only when the ratchet 2 and the pawl 3 are fully engaged, which can prevent the generation of the locking signal when a false lock occurs, greatly improving the safety of the driver and passengers. The motion dimension chain of the components involved in the signal output is shorter, and only the meshing surface between the ratchet 2 and the pawl 3 has strict dimensional tolerance requirements, which greatly reduces the dimensional requirements for the internal components of the door lock and has the characteristics of easy implementation. The signal triggering mechanism proposed by the present invention can be used without a micro switch, and the signal triggering does not depend on the quality performance of the micro switch, thereby improving the reliability of the vehicle lock. The signal triggering mechanism has the characteristics of a small number of components, a simple internal circuit, a small size, a light weight and a low cost, which helps to reduce the vehicle body wiring harness interface and helps to simplify the control logic of the vehicle lock.
