Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to an anti-theft device for convertible cars.

0002

[Conventional technology]

In a car, once a locked door is unlocked and opened with something other than the key, There are anti-theft devices that activate alarm devices (for example, Utility Model Application No. 61-100648). , see Utility Model Application Publication No. 60-148157).

0003

[Problem that the idea aims to solve]

Some cars have an open roof and a hood that can be opened and closed. Convertible cars are known, but in this convertible car, the hood can be opened. Occupants often leave the vehicle in a state where the vehicle is in an upright position. Therefore, such a combination If the vehicle is equipped with the above alarm system, the occupant returns to the vehicle and uses the key. There is a problem where the alarm goes off every time you unlock and open the door without Ru.

0004 Therefore, this idea was developed to ensure that either the top is closed or the door window glass is closed. Only in some cases, unlocking the door without using the key and opening the door will activate the alarm. The present invention provides an anti-theft device for convertible cars.

[0005]

[Means to solve the problem]

When the ignition switch is OFF and the door is closed and locked When you unlock and open the door with something other than the key, the roof detection means detects that the top is closed. or the door window glass detection means detects that the door window Controller that activates the alarm device when it detects that the ugarasu is closed It is equipped with

[0006]

[Effect]

Use the key only when the top is closed or the door window glass is closed. Set the alarm to activate when you unlock and open the door without opening the door. If the window glass or top is open, avoid activating the alarm system to prevent inconvenience. Eliminate harshness.

【Example】

An embodiment of this invention will be described below with reference to the drawings.

[0008] What is shown in FIG. 5 is a side view of the convertible type automobile 1. As shown in FIG.

[0009] A hood 3 is attached to a roof opening 2 of an automobile 1 so as to be openable and closable.

0010 When the top 3 is closed, there is a front roof rail 4 with which the front edge of the top 3 is in close contact. A roof switch 5 is provided as a roof detection means that is turned off when the vehicle is turned off.

[0011] On the other hand, what is shown in FIGS. 3 and 4 is the driver door 6. A door window glass 8 is supported by a lifting device 7 so as to be able to rise and fall. On the ascending and descending trajectory of the door window glass 8, there is a tree when the door window glass 8 is in the fully closed position. Door window glass inspection in which the cam 10 comes into contact with the rotation of the oil lever 9 and turns ON. A driver side door window switch 11 is provided as an exit means.

0012 In addition, the resin lever 9 and the driver side door window switch 11 are attached to the mounting bracket. to the door inner panel 14 which is joined to the door outer panel 13 via the bracket 12. installed. Note that this configuration also applies to the assist door (not shown).

[0013] The driver side door 6 also displays whether the door is locked or unlocked. A driver-side unlock sensor 14 detects whether or not the key is inserted. The driver side key cylinder switch 15 detects the open/closed state of the door. A door switch 16 is provided, and the assist door (not shown) is also connected to the driver door 6. Similarly, the assist side door switch 161, assist side unlock sensor 141, Assist side door window switch 111, assist side key cylinder switch 15 1 is provided.

[0014] Then, as shown in Fig. 1, the ignition switch 17, the driver side door door The switch 16 and the driver side unlock sensor 14 are connected to the timer 21, and the timer 21 is connected to the battery 19 and the controller 18.

[0015] Also, roof switch 5, driver side door window switch 11, driver side Key cylinder switch 15, driver side door switch 16, driver side unlock assist sensor 14, assist side door switch 161, assist side unlock sensor 1 41, Assist side door window switch 111, Assist side key cylinder switch The switch 151 connects the battery 19 and the alarm device (horn) 2 via the controller 18. Connected to 0.

[0016] Next, the operation will be explained according to the flowchart of FIG.

[0017] After the start (step 1), first check whether the ignition switch 17 is OFF or not. (Step 2), and if it is OFF, the driver side door switch 16 is OFF. The driver side unlock sensor 14 detects that the driver door is 6 is locked (step 3). In addition, lock the driver door 6. The assist door will then lock automatically.

[0018] When the locked state continues for 30 seconds due to timer 21, it becomes alert mode (step 4), at this time the top 3 is in the closed state, and the driver side key cylinder switch 15 is is off, the driver-side unlock sensor 14 detects the unlocked state. Or the assist side key cylinder switch 151 is OFF and the assist side is turned off. When the lock sensor 141 detects the unlocked state, the driver side or assist side door Driver door 6 or assist regardless of whether the window switch is ON or OFF. When the door is opened (step 8), an alarm (horn) sounds to issue a warning.

[0019] Similarly, even if hood 3 is open (step 5), the driver side and assist side When the door window switches 11 and 111 are ON (step 6), the dry When the bad door 6 or the assist door is opened (step 8), the alarm sounds (step 8). 9).

[0020] Therefore, either the hood 3 is closed or the left and right door window glasses are closed. If someone else unlocks either the left or right door from inside the vehicle without using the key, When the lock is opened, an alarm will sound to prevent theft.

[0021] On the other hand, the driver left the hood 3 and either the left or right window glass open. If you get off the car (steps 5 and 6), you are not in a situation where you should be careful about theft. Therefore, the driver returns to the vehicle and opens the driver door 6 or the assist door from inside the vehicle. Even if you unlock it and open it, the alarm will not go off. So just a little short Do not use the key when there is no risk of theft, such as when leaving the vehicle for an hour. This is convenient because the alarm does not sound even if you open or close the door.

[0022] In addition, in the flowchart of FIG. 2, when the ignition switch 17 is ON, (Step 2), the driver side door switch 16 is OFF and the driver door 6 is locked. When not locked (step 3), the driver door 6 is locked for 30 seconds. When not in use (Step 4) and driver side or assist side key cylinder switch 15, 151 is ON and driver door 6 or assist door is unlocked. (Step 7), the roof switch 5 is ON and the driver side door window switch is switch 11 or assist side door window switch 111 is OFF ( In step 6), it is determined again whether the ignition switch 17 is OFF or not. separated (step 2).

[0023] Also, the driver side and assist side door switches 16, 161 are turned on. If not (Step 8), turn the driver side or assist side key cylinder switch again. Is driver door 6 or assist door unlocked with switch 15, 151 ON? (Step 7).

[0024] In the example, the top 3 is closed or the left and right door window glasses are closed. If the door is unlocked and opened using any operation other than the key under these conditions, an alarm will sound. However, under the condition that both the hood 3 and the left and right door window glasses are closed, I set the alarm to sound when the door is unlocked and opened using an operation other than the key. Also good.

[0025]

[Effect of the idea]

As explained above, according to this invention, the top and door window glass can be opened. Then, turn off the ignition switch, lock the doors, and exit the vehicle. If the vehicle is damaged, the door must be unlocked and opened without using the key when re-entering the vehicle. However, the alarm system will not activate.

[0026] Therefore, even though the vehicle is equipped with an alarm system, the hood and door windows The alarm will not activate when the glass is open, so the key is always on. This has the effect of freeing you from the hassle of having to use the key to unlock the door. .

[0027] Also, if at least one of the hood and door window glass is closed, If you unlock and open the door without using the key, the alarm will activate, so Therefore, theft prevention can be ensured.
