Description

  The present invention relates to a slide door open / close state detection switch that can detect a fully closed state, a half door state, and a fully open state of a slide door.

FIG. 8 is a perspective view of a sliding door of a vehicle that is the background art of the present invention. FIG. 9 is a partially enlarged view of the vicinity of the hinge of the sliding door of FIG. In the figure, Fr indicates the vehicle front direction, OUT indicates the outdoor direction, and UPR indicates the vertically upward direction.
The slide door 21 of the vehicle 20 is connected to a hinge engaging portion 23 by upper and lower hinges 22. A hinge insertion opening 23a of the hinge engaging portion 23 is opened in the body facing the slide door 21 of the vehicle 20 in the front-rear direction of the vehicle. A guide rail 23b is disposed above the hinge insertion opening 23a. The guide roller 23c is inserted into the guide rail 23b so as not to drop off, and slides while rotating along the edge of the guide rail 23b. As shown in FIG. 9, the guide roller 23 c has a shaft 23 d that is attached vertically downward. One end of the hinge 22 is pivotally attached to the lower end of the shaft 23d. A flange 23e extends from the rear end of the guide rail 23b. A screw hole is formed in the flange 23e, and a stopper 23f with a bolt is passed through the screw hole and screwed with a nut 23g.
The slide door 21 of the vehicle 20 includes the above-described slide mechanism, and when the slide door 21 is changed from the fully closed state to the fully open state, the slide door 21 is pushed out to the outside of the vehicle width to Slide in the direction. A courtesy switch 25 is fixed to the body of the vehicle 20. The fixed portion is the surface of the panel 24 facing the rear side portion of the slide door 21 in a state where the slide door 21 is fully closed, and is a height at which the outer handle 21a of the slide door 21 is mounted.

10A is a front view of the courtesy switch of FIG. 8, and FIG. 10B is a cross-sectional view taken along line XX of FIG.
A hole formed in the base material 25a of the courtesy switch 25 is aligned with a hole in the panel 24, a bolt 25b is inserted, and the nut 25c is tightened. A shaft support portion 25d is fixed vertically above the hole into which the bolt 25b is inserted. The shaft support portion 25d protrudes inside the panel 24, that is, indoors. A shaft 25e is inserted into the shaft support portion 25d. The base material 25a, the head of the bolt 25b, the shaft 25e, and a part of the shaft support portion 25d are covered with rubber 25f.
In the shaft support portion 25d, the switch functions as ON according to the position of the shaft 25e, that is, in a state where the shaft 25e projects to the outdoor side (solid line state in FIG. 10B). In a state where 25e is pushed into the shaft support portion 25d (a dotted line state in FIG. 10B), the switch is configured to function as a switch OFF. The state of this switch is output as a signal from the connector 25g.

In the state where the slide switch 21 is not fully closed, the courtesy switch 25 having the above-described configuration has a shaft 25e that projects outwardly as shown by a solid line in FIG. It becomes a state. On the other hand, when the slide door 21 is fully closed, as shown by a broken line in FIG. 10B, the inner surface of the inner panel 21b of the slide door deforms the rubber 25f so that the shaft 25e is placed in the shaft support portion 25d. Thus, the courtesy switch 25 is turned off.
In this way, the courtesy switch 25 detects whether or not the slide door 21 is fully closed, and when the slide door 21 is not fully closed, for example, the room lamp is turned on or mounted on the indoor side. Operate a half-door warning lamp or buzzer to inform the driver.

  There is also an automatic sliding door that automates the sliding door of the vehicle. In this automatic sliding door, the sliding door is connected to an operation belt driven by a motor via a connection bracket, and the sliding door is opened and closed by the motor via this operation belt. A contact switch is attached in the vicinity of the connection bracket when the slide door is fully closed and fully opened, and the fully open state and the fully closed state of the slide door are detected by turning on and off each contact switch (for example, Patent Document 1). .

  In addition, as a drive device for opening / closing bodies such as sliding doors and sunrooms, the opening operation time when the opening / closing body slides in the opening direction from the fully closed state and the closing operation when sliding in the closing direction from the fully closed state There is a device that measures time and stops the driving means of the opening and closing body when a predetermined time elapses (for example, Patent Document 2).

  Some vehicles have a so-called rotary lift-up seat. The lift-up seat is electrically rotated, lifted up or down in consideration of those who have difficulty transferring to the vehicle.

Japanese Utility Model Publication No. 6-75835 No. 8-5854

By the way, in the background art shown in FIGS. 8 to 10, it is possible to detect whether or not the slide door 21 is fully closed, but it is not possible to detect whether or not the slide door 21 is fully opened. Therefore, in a vehicle equipped with a rotary lift up seat, an electric circuit for driving the rotary lift up seat cannot be operated only when the sliding door is fully open. Therefore, as shown in FIG. 11, in the circuit in which the courtesy switch 25 and the room light 26 are connected in series, the electric circuit 27 of the rotary lift-up seat and the switch is turned ON / OFF depending on whether or not the sliding door is fully opened. Need to be connected in series to the courtesy switch 25.
Moreover, in the technique described in Patent Document 1, it is necessary to mount the contact switches separately at predetermined positions. In the technique described in Patent Document 2, since the time from the start of opening and closing is measured, a timer is required, and it is estimated from the time whether the sliding door is fully opened or not. Therefore, the actual opening / closing state of the sliding door is not detected.

  In view of the above problems, an object of the present invention is to provide a single slide door open / close state detection switch that can detect the open / close state of a slide door.

In order to achieve the above object, the present invention provides a sliding door open / closed state detection switch for detecting an open / closed state of a slide door by contacting a rod disposed in the sliding direction of the slide door and a front rod of the rod. A first limit switch that detects the rearward displacement of the rod and changes the switching state; a second limit switch that detects the forward displacement of the rod and changes the switching state by abutting with the rear rod of the rod; The limit switch and the second limit switch are fixed to the inside, and the front and rear parts of the rod protrude from the housing to support the rod so that it can slide. It is characterized by that.
With this configuration, the open / closed state of the sliding door, that is, either the fully closed state, the fully open state, or the half door state can be detected by one unit.
Preferably, the front end of the rod abuts against the hinge side surface of the sliding door when the sliding door is fully opened, displaces the rod rearward, and changes the first limit switch from the OFF state to the ON state, while When the sliding door is fully closed, the end abuts against an elastic body fixed to the indoor side of the sliding door, displaces the rod forward, and changes the second limit switch from the ON state to the OFF state. With this configuration, the sliding door open / closed state detection switch can be made to function only by fixing the elastic body to the indoor side of the sliding door.
Preferably, the housing has a pair of housing members, and the housing member has a front flange extending rearward from the front end of the housing member and a rear flange extending forward from the rear end of the housing member. The rod is inserted into the first coil spring, the front end of the first coil spring is fixed to the rear end of the front flange, and the rear end of the first coil spring is fixed to the front end of the rod. The second coil spring is inserted and the front end of the second coil spring is fixed to the rear end of the rod, and the rear end of the second coil spring is fixed to the front end of the rear flange. The pair of housing members are opposed so that the rod is supported by the front flange and the rear flange of the housing member. With this configuration, the sliding door is changed from the fully closed state to the half door state by the action of the first coil spring and the second coil spring inserted into the rod, or conversely from the fully open state to the half door state. However, the switching state of the first limit switch and the second limit switch can be changed by easily displacing the rod in the front-rear direction.

The sliding door open / closed state detection switch of the present invention detects that the rod is displaced in the sliding direction as the sliding door slides, and the displacement direction is detected by the internal first limit switch and the second limit switch. Change the switching state. Therefore, the open / closed state of the slide door, that is, the fully closed state, the fully open state, or the half door state can be detected by one unit.
In addition, when the slide door open / close state detection switch is mounted on the vehicle, the slide door open / close state detection switch need only be fixed to the rear end of the guide rail, and an elastic body may be fixed to the indoor side of the slide door. It can also be mounted on various vehicles.
Furthermore, even if the slide door changes from a fully closed state to a half door state due to the action of the first coil spring and the second coil spring inserted into the rod, or vice versa. The rods can be easily displaced in the front-rear direction to change the switching states of the first limit switch and the second limit switch.

The best mode for carrying out the present invention will be described below with reference to the drawings. In the best mode for carrying out the present invention, a case will be described in which a sliding door open / closed state detection switch is mounted on the vehicle of FIG. 8 shown in the background art.
FIG. 1 is a perspective view of a vehicle equipped with a slide door open / close state detection switch for carrying out the present invention, FIG. 2 is a schematic perspective view of the slide door open / close state detection switch, and FIG. 3 is an arrow A direction of the slide door of FIG. FIG. 4 is a sectional view taken along line B-B in FIG. 2. In the figure, Fr indicates the vehicle front direction, OUT indicates the indoor direction, and UPR indicates the vertically upward direction.

As shown in FIG. 1, the slide door 2 of the vehicle 1 is connected to the upper and lower hinge engaging portions 3 by an upper hinge 2a and a lower hinge 2b. The hinge insertion port 3a of the hinge engaging portion 3 is opened in the front-rear direction of the vehicle in the body facing the slide door 2 of the vehicle 1.
Below, the hinge engaging part 3 by the side of the upper hinge 2a is demonstrated. A guide rail 3b is disposed above the hinge insertion opening 3a. A guide roller (not shown) is inserted into the guide rail 3b so as not to drop off, and the guide roller slides while rotating along the edge of the guide rail 3b. The guide roller has a shaft (not shown) pivoted vertically downward. One end of the upper hinge 2a is attached to the lower end of the shaft. As shown in FIG. 2, a collar 3c is extended at the rear end of the guide rail 3b. A mounting hole 3d having a diameter larger than that of the hole shown in FIG. 9 is formed in the collar 3c. A cord insertion opening 3e is opened at the lower end of the mounting hole 3d of the flange 3c. The output cord 4a of the slide door open / close state detection switch 4 is inserted into the cord insertion port 3e, and the slide door open / close state detection switch 4 is inserted into the mounting hole 3d. The slide door open / close state detection switch 4 is fixed to the flange 3c by being screwed with a screw thread formed on a part of the outer periphery of the slide door open / close state detection switch 4 with one or a plurality of nuts 4b.

  Further, when the sliding door 2 of the vehicle 1 is cornered, that is, when the sliding door 2 is fully closed, the sliding door open / closed state detection switch 4 is protruded on the nut 4b side fixed to the flange 3c. An elastic body 5 having a predetermined size is fixed (see FIG. 5 described later). For example, as shown in a perspective view (FIG. 3) as viewed from the arrow A in FIG. 1, a part of a screw 5 a is inserted into the elastic body 5 such as rubber and is formed in the inner panel 2 a of the slide door 2. The screw 5a is inserted into the hole 2c and screwed with the nut 5b.

Hereinafter, the sliding door open / closed state detection switch 4 will be described in detail with reference to FIG.
The slide door open / closed state detection switch 4 arranges rods 41 in the slide direction of the slide door 2, that is, in the vehicle front-rear direction. The rod 41 has a front rod 41a and a rear rod 41b at positions separated from the center of the rod by a predetermined distance. This predetermined distance is about 1/5 of the length of the housing 42, for example.
The rod 41 is supported and housed in the housing 42 so that the front and rear portions of the rod 41 can protrude and slide. The housing 42 has a pair of housing members 42a facing each other and a flange 42b fixed to the outer periphery thereof. For example, the housing 42 is formed in a hollow cylinder with a pair of housing members 42a facing each other. A side surface of the cylindrical vehicle in the front-rear direction has a hole through which the rod 41 is inserted. The flange 42b is joined to the flange 3c at the rear end of the guide rail 3b.
A front flange 42c having a predetermined width is extended inward from the front end of the housing member 42a, that is, in the rearward direction of the vehicle. Similarly, a rear flange 42d having a predetermined width is extended inward from the rear end of the housing member 42a, that is, in the forward direction of the vehicle. The shapes of the front flange 42 c and the rear flange 42 d are shapes corresponding to the shapes of the rods 41. For example, if the rod 41 is a substantially cylinder, the cross sections of the front flange 42c and the rear flange 42d are also arcs.

A first coil spring 43 a is attached to the rod 41. The front end of the first coil spring 43a is fixed to the rear end of the front flange 42c of the housing member 42a. The rear end of the first coil spring 43a is fixed to the front end of the front collar 41a.
Here, a first limit switch 44 is fixed inside the housing member 42. The first limit switch 44 is obtained by axially attaching a roller 44c to the end of a sliding body 44b that protrudes and slides from the limit switch body 44a. Due to the rearward displacement of the rod 41, the front rod 41a abuts against the roller 44c of the first limit switch 44 and the sliding body 44b is partially pushed into the first limit switch 44, so that the switch of the limit switch body 44a is in the OFF state. To ON state. This switching information is output from the code 4a.

The rod 41 is provided with a second coil spring 43b. The rear end of the second coil spring 43b is fixed to the front end of the rear flange 42d of the housing member 42a. The front end of the second coil spring 43b is fixed to the rear end of the rear collar 41b.
Here, a second limit switch 45 is fixed inside the housing member 42. The second limit switch 45 is obtained by axially attaching a roller 45c to the end of a sliding body 45b that protrudes and slides from the limit switch body 45a. Due to the forward displacement of the rod 41, the rear rod 41b comes into contact with the roller 45c of the second limit switch 45 and the sliding body 45b is partially pushed into the second limit switch 45, and the switch of the limit switch body 45a is in the ON state. To the OFF state. This switching information is output from the code 4a.

  The first coil spring 43a and the second coil spring 43b are inserted into the rod 41, and the rod 41 is supported by the front flange 42c and the rear flange 42d of the housing member 42a. In a state where the housing member 42 a is opposed, the front portion of the rod 41 protrudes from the front end of the housing 42. The rear part of the rod 41 protrudes from the rear end of the housing 42. An elastic body 46 such as rubber is passed through the front portion of the rod 41, and the rear end of the elastic body 46 and the front end of the housing 42 are joined. Further, an elastic body 47 such as rubber is passed through the rear portion of the rod 41 so that the front end of the elastic body 47 and the rear end of the housing 42 are joined. At the rear part of the elastic body 47, there is a recess of a recess 47a, and a ring 48, for example, an E ring, is inserted into the rod 41 in the recess 47a to prevent detachment. 4 shows the case where the ring 48 is inserted into the concave portion 47a of the elastic body 47, the concave portion is formed by recessing the front side of the elastic body 46, and the ring is attached to the rod 41 in this concave portion. Thus, the rod 41 may be prevented from slipping out of the housing 42.

The slide door open / closed state detection switch according to the embodiment of the present invention is configured as described above, and operates as follows. When the slide door 2 is not fully closed, the indoor lamp is turned on and the slide door 2 is not fully opened. A case where the electric circuit of the rotary lift-up seat is not operated will be described as an example.
FIG. 5 is a cross-sectional view of the slide door open / close state detection switch when the slide door is fully closed, FIG. 6 is a cross-sectional view of the slide door open / close state detection switch when the slide door is fully open, and FIG. It is a circuit schematic diagram which incorporated the sliding door open / closed state detection switch in the electric circuit of the rotary lift-up seat.

  In the fully closed state of the slide door 2, as shown in FIG. 5, the elastic body 5 fixed to the inner panel 2a of the slide door 2 with a nut 5c contacts the rear end of the rod 41, and the rod 41 is in front of the vehicle. It is displaced in the direction. In this state, the rear rod 41b pushes the sliding body 45b and the roller 45c of the second limit switch 45 toward the limit switch body 45a, and the switching state of the limit switch body 45a changes from the ON state to the OFF state. Therefore, in the circuit diagram of FIG. 7, the second limit switch 45 is turned off, and the interior light 5 is turned off. In this state, the front rod 41a does not contact the roller 44c of the first limit switch 44, and the limit switch body 44a of the first limit switch 44 remains in the OFF state. Therefore, in the circuit diagram of FIG. 7, since the first limit switch 44 is in the OFF state, the electric circuit 6 of the rotary lift-up seat cannot operate.

  When the sliding door 2 starts to open in this state, the elastic body 5 fixed to the sliding door 2 moves away from the rear end of the rod 41, and the first coil spring 43a extends and the second coil spring 43b contracts. As shown in FIG. 4, the spring is not elastic. In this state, the rear rod 41b does not contact the roller 45c of the second limit switch 45, the sliding body 45b of the second limit switch 45 protrudes from the limit switch body 45a, and the limit of the second limit switch 45 is reached. The switch body 45a changes from the OFF state to the ON state. Therefore, in the circuit diagram of FIG. 7, since the second limit switch 45 is in the ON state, the room light 5 is lit. In this state, the front rod 41a does not contact the roller 44c of the first limit switch 44, and the limit switch body 44a of the first limit switch 44 remains in the OFF state. Therefore, in the circuit diagram of FIG. 7, since the first limit switch 44 is in the OFF state, the electric circuit 6 of the rotary lift-up seat cannot operate.

  When the sliding door 2 is completely opened, as shown in FIG. 6, the side surface of the upper hinge 2a comes into contact with the front end of the rod 41, and the rod 41 is displaced in the rearward direction of the vehicle. That is, the first coil spring 43a extends and the second coil spring 43b contracts, and the rod 41 is displaced rearward. Then, the front rod 41a pushes the sliding body 44b and the roller 44c of the first limit switch 44 to the limit switch body 44a side, and the switching state of the limit switch body 44a is changed from the OFF state to the ON state. Therefore, in the circuit diagram of FIG. 7, the first limit switch 44 is in the ON state, so that the electric circuit 6 of the rotary lift-up seat can be operated. That is, the electric circuit 6 of the rotary lift-up seat can be operated to rotate or move the seat up and down. For example, since the slide door 2 is fully opened, the seat can be rotated by effectively utilizing the entire space in the opening formed by sliding the inner slide door 2 of the body. In this state, the rear rod 41b does not contact the roller 45c of the second limit switch 45, and the limit switch body 45a of the second limit switch 45 remains in the ON state.

  When the sliding door 2 starts to close from this state, the upper hinge 2a does not come into contact with the front end of the rod 41, the second coil spring 43b extends, and the first coil spring 43a contracts, as shown in FIG. The elastic force is not generated. In this state, the front rod 41a does not contact the roller 44c of the first limit switch 44, the sliding body 44b of the first limit switch 44 protrudes from the limit switch body 44a, and the limit switch of the first limit switch 44 The main body 44a changes from the ON state to the OFF state. Thus, in the circuit diagram of FIG. 7, the first limit switch 44 is in the OFF state, so that the electric circuit 6 of the rotary lift-up seat is not forced to operate. In this state, the rear rod 41b does not contact the roller 45c of the second limit switch 45, and the limit switch body 45a of the second limit switch 45 remains in the ON state.

As described above, the slide door open / close state detection switch 4 can detect whether the slide door 2 is fully closed, fully open, or half-door. That is, when the first limit switch 44 and the second limit switch 45 are in the ON state, the slide door 2 is in the fully open state. When the first limit switch 44 and the second limit switch 45 are in the OFF state, the slide door 2 is in the fully closed state. Further, when the first limit switch 44 is in an OFF state and the second limit switch 45 is in an ON state, the slide door 2 is in a half door state. By connecting this detection result to various electric parts of the vehicle, for example, the electric circuit 6 of the rotary lift-up seat, the wiring of the room light, the warning lamp, etc., each electric appliance is operated according to the open / closed state of the slide door Can be controlled.
Further, the slide door open / close state detection switch 4 can detect whether the slide door 2 is fully closed, fully open, or half door with a single unit. The place can be made into one place, and it doesn't take time to install.
Moreover, it is not necessary to prepare separately the element which detects that the slide door 2 is fully closed, and the element which detects that the slide door 2 is fully opened, and the cost does not increase.

  Also, the slide door open / closed state detection switch 4 is inserted by removing the bolted stopper 23f (see FIG. 9) fixed to the flange 3c at the rear end of the guide rail 3b and increasing the diameter of the hole. Can do. Therefore, it can be retrofitted to a vehicle equipped with a sliding door. Moreover, since the method of retrofitting is also simple, there are various types of vehicles in which the slide door open / closed state detection switch 4 can be inserted.

  The embodiment of the invention described above is merely a preferred embodiment of the present invention, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say. For example, although the case where the front end of the rod 41 is brought into contact with the upper hinge 2a is shown, the slide door open / closed state detection switch 4 may be mounted so that the front end of the rod 41 can be brought into contact with the lower hinge 2b.
