In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Example 1
An automobile front cover switch assembly is provided, as shown in fig. 1, comprising a first lock catch arranged on an automobile body, a main control lock 4 arranged on the inner side of an automobile front cover, an automobile lock sensor 2, a locking sensor 5 and an unlocking switch 3; wherein the front cover and the body of the automobile are locked with the buckle of the first lock catch through the master lock 4; the lock sensor 2 is connected with an ignition switch 1 of the automobile and judges whether the automobile is flameout or not according to the state of the ignition switch 1; the unlocking switch 3 is respectively connected with the vehicle lock sensor 2 and the main control lock 4, and when the vehicle lock sensor 2 judges that the vehicle is in a flameout state, the unlocking switch 3 can control the main control lock 4 and the first lock catch to be locked and unlocked; the locking inductor 5 is connected with the automobile front cover to judge whether the automobile front cover is in lock catch clamping connection with the automobile body.
Specifically, the ignition switch 1 may be started by a keyless remote control or may be started by a vehicle key with a key cylinder. The unlocking switch 3 can be arranged in the vehicle, and can be arranged at the setting position of an opening handle at the lower part of the existing instrument desk, or can be arranged on a vehicle key to be started by remote control. The unlock switch 3 may be a switch for controlling the current of the circuit, a switch for controlling the on/off of the circuit, or a controller for sending a control signal, and the present embodiment is not particularly limited.
It should be understood that the control process among the unlocking switch 3, the vehicle lock sensor 2 and the main control lock 4 can be realized by simple circuit on-off by using the electric connection of circuit wires, and can also be connected to a vehicle body control system to enhance the control efficiency. That is, "the connection" in "the unlocking switch 3 is respectively connected with the lock sensor 2 and the master lock 4" may be an electrical connection or a communication connection, that is, the lock sensor 2 completes the operability of the unlocking switch 3 through a simple circuit on/off, or sends a control signal to make the unlocking switch 3 operable, so that the unlocking switch 3 may be further used to control the master lock 4.
More specifically, the lock sensor 2 may be a simple circuit switch, when the ignition switch 1 is a common plug-in key cylinder, the key is plugged to the end, and when the lock sensor 2 is touched, the circuit is broken to determine that the vehicle is not flameout, and when the key is pulled out and the switch of the lock sensor 2 is bounced, the vehicle is determined to be flameout, and the circuit is closed. The lock sensor 2 may also be a pressure-sensitive sensor that determines whether the vehicle is turned off by recognizing a pressed state of the key when inserted, for example, the ohong MEMS pressure sensor 2SMPP-02 ultra-small. In addition, the vehicle lock sensor 2 may be a sensor that determines feedback of the optical sensor when the optical sensor is inserted by an identification key, or may be a sensor that determines a signal of remote ignition of the vehicle by identification, or a sensor that sends a signal to the vehicle controller when the vehicle is in a flameout state.
Further, the lock sensor 5 may be an optical sensor, a vibration sensor, or a press sensor as long as it can determine that the front cover is in contact with the vehicle body. The locking sensor 5 is connected with the front cover of the automobile, and judges whether the front cover of the automobile is in lock catch clamping connection with the automobile body, so that other controls can be further carried out, for example, an alarm can be given out when the contact between the front cover and the automobile body is abnormal, or the main control lock 4 is controlled to be locked after the contact between the front cover and the automobile body is detected. The latching sensors 5 are of a type that does not require a small sensor to display readings, such as a low power MEMS gauge pressure sensor.
When the automobile lock is used, the automobile lock sensor 2 judges whether the automobile is flameout or not by identifying the state of the ignition switch 1 of the automobile, so that the front cover can be opened by taking the flameout of the automobile as a necessary condition for opening the front cover and judging the current automobile state, and the main control lock 4 can be opened. Compared with the first lock unlocking in the prior art, the first lock unlocking method based on the automobile flameout as a necessary condition for unlocking the front cover is more suitable for the operation habit of a driver, and is safer without the risk of opening the front cover because the automobile is still running. And then the unlocking switch 3 is controlled to control the main lock 4 and the first lock catch to unlock, so that the front cover is opened. Compared with the prior art, the driver only needs to operate the unlocking switch 3 once to open the front cover, and does not need to walk to the headstock to find the handle and do not need to repeatedly unlock the lock, so that the problems that the repeated unlocking operation is needed in the prior art and the risk of clamping hands of the front cover caused by the driver finding the headstock to lock the handle are solved.
According to another specific embodiment of the present invention, the embodiment of the present invention discloses a front cover switch assembly for an automobile, wherein the main control lock 4 comprises a first electromagnetic lock cylinder and a first buckling part capable of being driven by the first electromagnetic lock cylinder; the first electromagnetic lock cylinder is electrically connected with the unlocking switch 3 and is controlled to be powered on or powered off through the unlocking switch 3.
Specifically, the main control lock 4 is an electromagnetic lock, and after the main control lock is powered on, the first electromagnetic lock cylinder generates electromagnetic force to attract the first buckling part, so that the first buckling part is separated from the first lock buckle to complete unlocking.

Specifically, when the front cover needs to be opened, after the vehicle lock sensor 2 senses that the vehicle is turned off, the electromagnetic member 7 is energized to attract the second buckling portion to be separated from the lock catch, so that the inductive lock 6 is opened, and at this time, the driving force (electromagnetic force) of the electromagnetic member 7 is not enough to enable the first buckling portion to be separated from the lock catch. Furthermore, as the vehicle lock sensor 2 enables the circuit where the unlocking switch 3 is located to be electrified, the unlocking switch 3 can control the electromagnetic component 7, the unlocking switch 3 is operated to increase the current, so that the driving force of the electromagnetic component 7 is increased, the first buckling part is further attracted to be separated from the lock catch to unlock the main control lock 4, and the front cover is opened.
It should be understood that the unlocking switch 3 in this embodiment may be a resistance switch, or other switches that can control the current magnitude of the circuit in which the first electromagnetic lock cylinder and the second electromagnetic lock cylinder are located. The electromagnetic member 7 may be an electromagnet.
By adopting the scheme, the locking and unlocking of the induction lock 6 and the main control lock 4 can be completed by using one lock catch and one electromagnetic component 7. In addition, what the unblock switch 3 that this embodiment used was connected with sense lock and the master control lock 4 of protecgulum is the electric wire, and the electric wire is softer for the steel wire line relatively, can adapt to more complicated front deck overall arrangement, reduces the exposure risk to reduce the opening force, make interior card handle paste more and make the profile with whole.
