Description

  The present invention relates to an automatic locking device for an automobile door.

  In particular, the present invention has a lock that cannot be accessed from the outside of the door, and the lock can be automatically locked under certain conditions in connection with the state of the engine key or the state of the transmission and the vehicle speed sensor. About.

  Since the present invention can be particularly suitably used for automatic locking of a cargo compartment door of an automobile (freight vehicle) that carries cargo, an automatic locking device for a cargo compartment door of a cargo vehicle will be described below as an example. . However, this does not mean that the automobile to which the present invention is applied is limited to a freight vehicle, nor is the intention to limit the applicable door to a cargo compartment door.

  In general, an automobile for carrying cargo is provided with a cargo compartment in the loading platform, and the cargo compartment is opened and closed by a driver or a person who loads and unloads luggage from the outside. Yes.

  The cargo compartment door of the freight vehicle is provided with a device that is closed from the outside so that the door is not accidentally opened during operation. As the closing device, a device such as a yoke is widely used.

A conventional locking device for a cargo compartment door of a freight vehicle is a combination of a lock that prevents the rod of the closing device from being pulled out.

  However, there is a high possibility of being stolen with a conventional cargo compartment locking device of a freight vehicle.

  In particular, when unloading a package at a delivery destination, the time for delivering the package is short, and the vehicle is often left without locking the cargo compartment closure device. For this reason, it was often the case that luggage in the cargo compartment was stolen during a short period of time when the person left the car.

  In order to prevent such theft, conventionally, a package delivery person is required to lock the cargo compartment door when leaving the vehicle. However, in order to shorten the delivery time, it has been difficult to lock thoroughly.

  Therefore, it has been desired to develop an automatic locking device that automatically locks the door of the cargo compartment when a person leaves the vehicle.

  Moreover, in the conventional locking device of a freight vehicle, even if it was locked, it might be stolen.

  The reason is that the conventional locking device for the cargo compartment door of the freight vehicle can be accessed from the outside to the lock.

  The conventional locking device for the cargo compartment door of a freight vehicle can access the lock through the keyhole, etc., even if the lock device is locked separately from the closing device, even if it is a built-in lock. . As long as the keyhole exists, the lock may be unlocked by picking or the like. In other words, no matter what locks were used, a means for unlocking was eventually found, and theft could not be completely prevented.

  On the other hand, various devices that automatically lock by personal authentication or remote operation using communication technology have been proposed, but the structure has to be complicated.

  Therefore, the problem to be solved by the present invention is that it has an internal lock that cannot be accessed from the outside due to a simple structure, and automatically locks from the inside of the door depending on the state of the car when loading and unloading the luggage. An object of the present invention is to provide an automatic locking device for an automobile that can be used.

  The inventor of the present invention considers that one of the causes of the theft is that the lock can be accessed from the outside, uses the lock that cannot be accessed from the outside, and automatically loads and unloads the package.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  First, the lock pin and the hook of the locking device of the present invention will be described, and then the control of the controller of the present invention will be described.

  FIG. 1 is a perspective view of a lock pin and a hook according to an embodiment of the present invention.

  Reference numeral 1 denotes the entire hook. Reference numeral 2 denotes the head of the lock pin 2.

  Although the hook 1 and the lock pin 2 are originally engaged with each other, FIG. 1 shows the lock pin 2 slightly below in order to clarify the structure of the locking device.

  The hook 1 includes a hook support fitting 3, a hook member 4, a rotation limiter 5, and a magnet catcher 6.

  The hook support fitting 3 is attached to the inside of an automobile door (not shown).

  The hook member 4 is pivotally attached to the hook support fitting 3 by a rotating shaft 7. An engagement hole 8 for engaging with the lock pin 2 is provided at the tip of the hook member 4.

  The rotation limiter 5 is for preventing the hook member 4 from excessively rotating and drooping when the door is open, and colliding with the loading platform or the like of the automobile when the door is closed. The rotation limiter 5 engages with the lower end of the hook member 4 so that the hook member 4 does not rotate more than horizontal and prevents the hook member 4 from colliding with the loading platform of the vehicle when closing the door of the vehicle. can do.

  The magnet catcher 6 holds the hook member 4 in a vertical state. The magnet catcher 6 can hold the hook member 4 in a vertical state when the door of the automobile is open, and prevent the hook member 4 from projecting in the lateral direction and obstructing work.

  FIG. 2 is a top view of the locking device of FIG.

  FIG. 2 clearly shows the locking mechanism of this embodiment.

  As shown in FIG. 2, the hook support fitting 3 is attached to the door 9 of the automobile, and the lock pin 2 is attached to the loading platform 10 of the automobile.

  The hook member 4 pivots between a vertical state and a horizontal state. The horizontal position of the hook member 4 is a position where the hook member 4 engages with the lock pin 2.

  As for the lock pin 2, the pin rod 11 can move up and down. When the pin rod 11 is raised, the pin rod 11 is inserted into the engagement hole 8 of the hook member 4 and engages with the hook member 4.

  When the pin rod 11 is engaged with the engagement hole 8 of the hook member 4, the automobile door 9 and the automobile loading platform 10 are integrally coupled via the hook member 4 and the pin rod 11. Thereby, locking is realized.

  FIG. 3 shows a mechanism for locking the locking device of the present embodiment.

  The hook 1 is attached to the door 9 of the automobile, while the lock pin 2 is attached to the loading platform 10 of the automobile.

  The hook member 4 of the hook 1 is held in a vertical state by the magnet catcher 6 when the door 9 of the automobile is opened ((a) in FIG. 3). When the hook member 4 is vertical, the lower end of the hook member 4 is high enough to engage with a step formed on the loading platform 10 of the automobile.

  When the automobile door 9 is closed, the automobile door 9 moves in the direction of arrow A in FIG. Before the door 9 of the automobile is completely closed, the lower end of the hook member 4 is engaged with the step of the loading platform 10 of the automobile ((b) of FIG. 3). When the lower end of the hook member 4 is pushed by the step of the loading platform 10 of the automobile, the hook member 4 falls down, and the hook member 4 pivots to the engagement position with the lock pin 2 ((c) in FIG. 3).

  The lock pin 2 has a pin rod 11 and a rod holder 12 incorporating a driving means such as a combination of an electromagnetic coil and a spring. As the driving means, any known means other than the electromagnetic coil and the spring can be used.

  The pin rod 11 moves up and down inside the rod holder 12 by energizing the electromagnetic coil of the driving means. As described above, when the pin rod 11 is raised, it is locked, and when the pin rod 11 is lowered, it is unlocked.

  Therefore, according to the present embodiment, when the door 9 of the automobile is closed, the hook member 4 is pushed to the loading platform 10 of the automobile and pivots to the engagement position, and the pin rod 11 is raised and locked after a certain period of time. The On the contrary, if the pin rod 11 descends from the locked state, the unlocked state is entered, and the automobile door 9 can be opened.

  The above is the description of the structure and operation of the locking device hook 1 and the lock pin 2 of the present embodiment.

  In the locking device of the present embodiment, the lock pin 2 is attached to the floor of the car bed 10 inside the door, and the hook 1 is attached to the inside of the door 9.

  Thereby, the locking device of this embodiment has a part to be unlocked / locked inside the door, and the door is locked from the inside when the door is locked. That is, the locking device of the present embodiment has no means for accessing from the outside including the keyhole. For this reason, even if a means for unlocking the lock is found, the lock cannot be accessed from the outside of the door 9 of the automobile, and unlocking by an operation on the lock such as picking can be prevented.

  Next, processing of the locking device of this embodiment will be described.

  FIG. 4 shows a block diagram for the control of this embodiment.

  The automobile automatic locking device 20 of the present embodiment includes a hook 1, a lock pin 2, a door sensor 21, an engine key sensor or a stop sensor 22, a controller 23, and an LED display means 24.

  The controller 23 has a timer 25.

  The door sensor 21 is preferably attached in the vicinity of the upper end of the door 9 of the automobile, and outputs a signal indicating the open / closed state of the door 9 of the automobile.

  The engine key sensor or the stop sensor 22 is means for detecting that the automobile is in a stopped state.

  The engine key sensor 22 detects that the engine key is in the engine stop position or is in a state in which the engine key is removed, and outputs a signal indicating this. The stop sensor 22 detects that the transmission of the automobile is at the stop position or the vehicle speed is zero, and outputs a signal indicating the detection.

  The controller 23 receives signals from the door sensor 21, engine key sensor or stop sensor 22, performs a predetermined process, and outputs a lock command signal to the lock pin 2 under a predetermined condition.

  The LED display means 24 is means for notifying a driver or the like that the vehicle is locked. The LED display means 24 is operated by a signal from the controller 23. The LED display means 24 is not an essential component for the present invention and can be omitted as appropriate.

  FIG. 5 shows the flow of processing in the controller 23.

  In the present invention, there is no intrusion into the vehicle from the outside during driving of the vehicle, so that the unlocked state is during driving of the vehicle. In the flowchart of FIG. (Step 100).

  The controller 23 that has started the process determines whether or not a stop signal is output from the engine key sensor or the stop sensor 22 in a certain time cycle (step 110). The stop state signal is a signal that is output when the engine key sensor 22 detects that the engine key is in the engine stop position or the engine key has been removed, and the stop sensor 22 This signal is output when it is detected that the transmission is at the stop position or the vehicle speed is zero.

  If the stop signal is not received in the determination in step 110, the process returns, and the same determination is made again in a fixed time cycle.

  On the other hand, if it is determined in step 110 that a stop signal is received, the process proceeds to the next process, and it is determined whether a door open signal is input from the door sensor 21 (step 120).

  If the door sensor 21 does not input the door open state signal in step 120, it is the same as the door sensor 21 receiving the door close state signal.

  At this time, since the vehicle is in a stopped state and the door 9 of the vehicle is closed, the timer 25 counts the time from when the state is reached, and the counted time is sent to the controller 23. Entered.

  When the time count of the timer 25 reaches a predetermined time, the controller 23 outputs a locking command signal to the lock pin 2 (step 150).

  Step 150 is a process for automatically locking the vehicle when the door 9 of the automobile cannot be opened after a predetermined time has elapsed after the vehicle stops. Thereby, when there is no plan of loading and unloading of luggage, it is automatically locked when it stops for a long time.

  On the other hand, in step 120, when the door open signal is input from the door sensor 21 before the predetermined time in step 150 has elapsed (Yes in step 120), the controller 23 indicates that the door has been closed again. It is determined whether or not a signal indicating the input is present (step 130).

  While the door close signal is not input, the unlocked state of the lock pin 2 is maintained, and the same determination is made again in a certain time cycle (No branch of step 130).

  In step 130, when the controller 23 inputs a signal indicating that the door is closed from the door sensor 21, this indicates that the door has changed from the open state to the closed state. The counted time is input to the controller 23.

  When the time count of the timer 25 reaches a predetermined time, the controller 23 outputs a locking command signal to the lock pin 2 (step 140).

  Step 140 is a process for automatically locking when the vehicle door 9 is opened and closed again after the vehicle stops. As a result, the door 9 is opened for loading and unloading, and the door 9 is automatically locked when the door is closed after the operation is completed.

  As described above, according to the processing of the controller 23 of the present invention, after stopping, there is a case where the vehicle is parked for a long time without opening the door of the cargo compartment or the case where the cargo is unloaded and temporarily left the vehicle. Can be locked automatically.

  In particular, by setting a predetermined time until the locking command is output to the lock pin 2 in step 140 to be relatively shorter than the predetermined time in step 150, until the cargo compartment door is opened after stopping in a freight vehicle or the like. If the cargo compartment door is closed after the baggage is unloaded, it can be automatically locked immediately.

  Of course, the predetermined time of step 140 and step 150 is made the same, the processing of steps 130 and 140 is omitted, and only the processing of step 150 is unified, and the timer is simply started when both the stop state and the door closed state are satisfied. 25 starts counting time, and when the counted time reaches a predetermined time, the controller 23 outputs a locking command to the lock pin 2.

  The simplified processing flow is shown in FIG. In FIG. 6, the same processes as those in FIG. 5 are denoted by the same reference numerals.

  In FIG. 6, step 125 is substantially the same as step 120 in FIG. 5, except that the expression is changed to “door closed signal”.

  6, the position of step 150 is different from that of FIG. 5, but corresponds to the expression of step 125 described above, and is substantially the same as the process of step 150 of FIG. 5.

  According to the processing of FIG. 6, the processing is simplified, and the time until automatic locking after stopping is the same as the time until automatic locking after loading and unloading.

  This completes the description of the present embodiment.

  In the above description, the freight vehicle has been described. However, the object of the present invention is not limited to the freight vehicle, and the door is not limited to the freight compartment door. That is, the present invention can be applied to any vehicle type and door as long as it is a door that opens and closes after stopping and should be automatically locked after opening and closing.

  In the above-described embodiment, the hook member 4 engages with the vehicle bed 10 and pivots. However, the hook member 4 is not limited to the vehicle bed 10 but engages with a part of the vehicle body. do it.

  In the above embodiment, the hook member 4 is adapted to pivot by engaging with the loading platform 10 of the automobile, but the driving means for driving the hook member 4 to a position where it engages with the lock pin 2. May be provided. A motor or the like is conceivable as such driving means.

  In this case, when the controller 23 inputs a signal indicating that the door is closed from the door sensor 21, the controller 23 immediately outputs a command to the driving means of the hook 1 to drive the hook member 4 to the engagement position with the lock pin 2. Is preferred.

  Moreover, in the said embodiment, the hook 1 and the lock pin 2 were the engagement structure of the hook member 4 and the pin rod 11, However, if it is the same as the principle of this invention, what kind of well-known locking device can be used. it can. For example, it has a locking device that has a rod and the rod slides in the axial direction so that the tip is inserted into the receiving hole, and a rocking member that swings at the tip. A locking device or the like in which the formed hook is inserted into the receiving hole can be appropriately employed.
