Description

Technical Field

[0001] This utility model relates to the field of electronic lock technology, specifically to an electronic lock signal triggering device and an automobile. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the number of charging piles is increasing, and new energy vehicle charging is characterized by high current and high voltage. In order to improve the safety of fast charging of new energy vehicles, according to the national standard GBT-20234.1-2015, in order to prevent safety accidents caused by the charging gun being accidentally pulled out during the charging process, a locking device, namely an electronic lock device, needs to be installed between the charging gun and the charging socket.

[0003] Most electronic locks on the market today rely on microswitches to trigger signals to control the locking of the electronic lock. However, this type of structure often suffers from problems such as poor contact, failure of the load to start, insulation failure, loose springs, and aging and burning of the insulation layer, which greatly shortens its lifespan in actual use.

[0004] Meanwhile, in practical applications, electronic locks often need to be designed according to the charging socket, meaning that the size of the electronic lock is limited by the size of the charging socket. Furthermore, micro-switch-type signal triggering devices occupy a large space, which reduces the space available for other structures inside the electronic lock, resulting in a significant deviation between the final product design and the original design concept. Utility Model Content

[0025] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0026] Firstly, such as Figure 1 As shown, this embodiment provides an electronic lock signal triggering device, which includes a PCB circuit board 100, a motor 200, and a metal plate 300. The motor 200 is electrically connected to the PCB circuit board 100, and the PCB circuit board 100 is connected to an external power supply device, so that the external power supply device can supply power to the PCB circuit board 100 and the motor 200. The metal plate 300 is disposed on the output shaft of the motor 200. When the output shaft of the motor 200 rotates, the output shaft of the motor 200 can drive the metal plate 300 to reciprocate in a fixed direction.

[0027] Furthermore, the PCB circuit board 100 is electrically connected to a controller, enabling signal exchange between the PCB circuit board 100 and the controller. A trigger area is provided on the PCB circuit board 100, located along the path of the metal plate 300 moved by the motor 200. After assembling the PCB circuit board 100, the motor 200, and the metal plate 300, the metal plate 300 connected to the motor 200 can be pressed onto the PCB circuit board 100. When the motor 200 moves the metal plate 300, the metal plate 300 remains in contact with the PCB circuit board 100. Similarly, when the metal plate 300 moves within the trigger area, it also remains in contact with the trigger area.

[0028] When the motor 200 drives the metal plate 300 to move within the trigger area, the metal plate 300 can come into contact with different positions within the trigger area. By design, different positions within the trigger area have different functions, so that when the metal plate 300 moves to the corresponding position, the PCB circuit board 100 can generate a corresponding trigger signal and transmit it to the controller. After receiving the corresponding trigger signal, the controller analyzes it and controls the electronic lock to perform the corresponding action.

[0029] It should be noted that, compared with electronic locks currently on the market that rely on microswitches for control, the electronic lock signal triggering device in this embodiment can better avoid problems such as poor contact, load failure, insulation layer failure, and insulation layer aging and erosion, thus extending its service life and providing high stability. Furthermore, the electronic lock signal triggering device in this embodiment can be designed separately from the electronic lock itself, allowing for further reduction in the size of the electronic lock and providing better design flexibility.

[0030] In some embodiments, the output shaft of the motor 200 is connected to a worm gear 400. When the motor 200 is working, the output shaft of the motor 200 can drive the worm gear 400 to rotate. A worm wheel 410 is sleeved on the worm gear 400. When the worm gear 400 rotates, the worm wheel 410 on the worm gear 400 can be driven, so that the worm wheel 410 can move along the axial direction of the worm gear 400.

[0031] Furthermore, the position of the trigger area on the PCB circuit board 100 corresponds to the position of the worm gear 400; the metal plate 300 is disposed on the worm wheel 410. When the worm wheel 410 is driven by the worm gear 400, the metal plate 300 can move along the worm wheel 410 in the axial direction of the worm gear 400, thereby enabling the metal plate 300 to move in the trigger area, so that the metal plate 300 can cooperate with different positions of the trigger area and generate corresponding trigger signals, ultimately realizing the control of the electronic lock.

[0032] In some embodiments, a drive wheel 210 is sleeved and fixed on the output shaft of the motor 200, and a driven wheel 420 is sleeved and fixed on the worm 400. When the motor 200 and the worm 400 are assembled, the drive wheel 210 can mesh with the driven wheel 420, allowing the output shaft of the motor 200 to transmit torque to the worm 400 through the drive wheel 210 and the driven wheel 420, thereby driving the worm 400. It is understood that by adding the drive wheel 210 and the driven wheel 420 between the output shaft of the motor 200 and the worm 400, the stability and safety of the motor 200 driving the worm 400 can be significantly improved, and the motor 200 can be protected to a certain extent.

[0033] In some embodiments, a mounting groove 411 is provided on the side of the worm gear 410 near the PCB circuit board 100. As the worm gear 410 moves with the worm 400, the opening of the mounting groove 411 always faces the PCB circuit board 100. A portion of the metal sheet 300 can extend into the mounting groove 411 to facilitate the installation and use of the metal sheet 300 on the worm gear 410.

[0034] Furthermore, a spring 412 is provided between the mounting groove 411 and the metal plate 300. Specifically, one end of the spring 412 abuts against the inner end of the mounting groove 411, and the other end of the spring 412 abuts against the metal plate 300. In the installed state, the spring 412 is in a compressed state, which makes the spring 412 tend to push the metal plate 300 outward toward the mounting groove 411, so that the metal plate 300 can stably contact the PCB circuit board 100 and the trigger area, which can better improve the stability of the overall mechanism.

[0035] Understandably, because spring 412 has better elastic deformation, the entire movement of metal sheet 300 can have better buffering capacity, which can better protect metal sheet 300, PCB circuit board 100 and trigger area, thus extending service life.

[0036] In some embodiments, the trigger area disposed on the PCB circuit board 100 is a sheet conductor attached to the surface of the PCB circuit board 100, which is composed of a first conductor 110 and a second conductor 120 arranged in parallel with each other.

[0037] Furthermore, a first pin 310 and a second pin 320 are formed on one end of the metal sheet 300 near the PCB circuit board 100. The first pin 310 corresponds to the first conductor 110. When the worm gear 410 moves, the first pin 310 can abut against the first conductor 110 and slide. The second pin 320 corresponds to the second conductor 120. When the worm gear 410 moves, the second pin 320 can abut against the second conductor 120 and slide.

[0038] It is understandable that, since the metal sheet 300 is made of metal and has a certain conductivity, when the first foot 310 of the metal sheet 300 abuts against the first conductor 110 and the second foot 320 of the metal sheet 300 abuts against the second conductor 120, the conduction between the first conductor 110 and the second conductor 120 can be achieved better.

[0039] It should be noted that when the corresponding area on the first conductor 110 and the corresponding area on the second conductor 120 are mutually conductive under the action of the metal sheet 300, the PCB circuit board 100 can generate a trigger signal, which is then sent to the controller, so that the controller can control the electronic lock according to the trigger signal.

[0040] In some embodiments, a break region 111 is provided at the middle position of the first conductor 110. The break region 111 does not have conductive properties. That is, when the first foot 310 of the metal sheet 300 moves and abuts against the break region 111, the first conductor 110 and the second conductor 120 are disconnected.

[0041] It should be noted that the design is such that when the first foot 310 of the metal sheet 300 moves and abuts against the disconnection area 111, the first conductor 110 and the second conductor 120 change from a conductive state to a disconnected state. At this time, a trigger signal can also be generated, so that the controller can control the electronic lock to perform corresponding actions after receiving the trigger signal.

[0042] In some embodiments, the sheet conductor is made of gold foil, that is, the first conductor 110 and the second conductor 120 are made of gold foil. Of course, the sheet conductor can also be made of other conductive materials, which are not particularly limited here.

[0043] Secondly, this embodiment provides a car that includes the aforementioned electronic lock signal triggering device, and thus possesses the corresponding technical effects and advantages described above.

[0044] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
