Description

The present invention relates to a vehicle door check device.

For example, Patent Document 1 below discloses a vehicle door attached to an opening (entrance / exit) of a vehicle. The vehicle door has a door panel rotatably attached to the opening via a hinge. The door panel is composed of an outer panel arranged on the outside of the passenger compartment and an inner panel arranged on the inner side of the passenger compartment. The edges of the outer panel and the inner panel are welded together to form a door panel. A space is formed between the outer panel and the inner panel. That is, the door panel is hollow. A door lock device is installed inside the door panel.

The door lock device includes a latch mechanism that engages with a striker provided on the inner peripheral portion of the opening of the vehicle to hold the vehicle door in a closed state. Further, the door lock device includes a release mechanism for releasing the engagement between the latch mechanism and the striker.

Further, the vehicle door of Patent Document 1 includes an electric actuator (latch release actuator) for driving the release mechanism.

The electric actuator (latch release actuator) is controlled by a vehicle control device (ECU). For example, when the user operates a predetermined operation unit (switch, sensor, etc.), a predetermined trigger signal is output from the operation unit. The control device receives the trigger signal and controls the electric actuator.

Further, the vehicle door of Patent Document 1 includes a door check device. The door check device includes a long door check lever and a shoe that presses (pinches) the side surface of the door check lever. The door check lever is arranged in the door panel. As the door panel opens and closes, the door check lever moves back and forth with respect to the door panel. A recess is provided on the side surface of the door check lever, and the opening degree of the door panel is maintained by fitting the shoe into the recess.

Japanese Unexamined Patent Publication No. 2007-10342

When the door panel is completely closed (fully closed), the shoe is in contact with the tip of the door check lever. The portion of the tip of the door check lever that the shoe is in contact with is an inclined surface that is inclined with respect to the longitudinal direction of the door check lever (see FIG. 10). Here, the shoe presses the door check lever in a direction perpendicular to the longitudinal direction of the check lever. Therefore, when the shoe presses the inclined surface of the door check lever in the fully closed state, the component force of the force is applied in the direction parallel to the longitudinal direction of the door check lever. At that time, the inclined surface is set so that the component force acts in the direction in which the door check lever is pulled into the door panel. That is, in the fully closed state, the door panel is urged in the closing direction by the shoe.

Therefore, for example, in a vehicle in which the handle portion (outside door handle) is omitted, even if the latch mechanism and the striker are disengaged by using the electric actuator, the door panel is hardly opened. In this case, it is difficult for the user to open the door. Therefore, the vehicle door of Patent Document 1 has an urging device (spring) for urging the door panel in the opening direction in the fully closed state. According to this, when the latch mechanism and the striker are disengaged by using the electric actuator, the door panel is urged in the opening direction by the urging device, and the door panel is slightly opened. A user who wants to get into a vehicle can open the door panel wide by putting his / her hand on the edge of the door panel and pulling it to the outside of the passenger compartment.

As described above, when the door check device of Patent Document 1 is used, an urging device different from the door check device is required. Therefore, the number of parts constituting the vehicle door is large.

The present invention has been made to address the above problems, and an object of the present invention is to provide a vehicle door check device capable of shifting a door panel from a fully closed state to a pop-up state. In the following description of each component of the present invention, in order to facilitate understanding of the present invention, the reference numerals of the corresponding parts of the embodiments are described in parentheses, but each component of the present invention is described. It should not be construed as limited to the configuration of the corresponding parts indicated by the reference numerals of the embodiments.

In order to achieve the above object, the vehicle door check device (40) according to the present invention keeps the opening degree of the vehicle door panel (11) at a predetermined value. This vehicle door check device is housed in the door panel, and is slid on a long door check lever (41) that moves forward and backward with respect to the door panel as the door panel is opened and closed, and a side surface portion of the door check lever. A shoe (42U, 42L) that comes into contact with the door is provided, and the side surface portion of the door check lever has a first inclined surface (SF _R1U , SF _R1L ) that is inclined with respect to the longitudinal direction thereof, and the door panel is closed. In the held state, the door check lever is pressed so that the first inclined surface of the door check lever is pressed by the shoe to apply a force to the door panel in the direction in which the door panel is opened. Is urged by the shoe.

In the vehicle door check device according to one aspect of the present invention, the side surface portion of the door check lever is a second inclined surface (SR _R1U , SR _R1L ) inclined with respect to the longitudinal direction thereof, and the first inclined surface. It has a second inclined surface that faces the surface and is inclined in a direction opposite to the first inclined surface.

Further, in the vehicle door check device according to another aspect of the present invention, the inclination angle of the first inclined surface with respect to the longitudinal direction of the door check lever is larger than the inclination angle of the second inclined surface.

In the closed state (fully closed state) of the door panel, the door panel can be urged in the opening direction by pressing the first inclined surface of the door check lever with the shoe. Therefore, it is not necessary to provide an urging device (electric actuator, spring, etc.) for shifting the door panel from the fully closed state to the slightly opened state (pop-up state) separately from the vehicle door check device. Therefore, according to the present invention, the number of parts is smaller than that in the case where the urging device as described above is provided.

In one aspect of the present invention, the door check lever includes a first side surface portion and a second side surface portion, and the first inclined surface and the second inclined surface are formed on the first side surface portion, and the check lever is formed. Of these, an interference structure that interferes with the second side surface portion is provided in a predetermined range including a boundary portion between the portion where the first inclined surface is formed and the portion where the second inclined surface is formed. In this case, the interference structure includes a convex portion provided on the second side surface portion and a sliding contact portion that is in sliding contact with the convex portion.

According to this, in the process from the fully closed state to the pop-up state of the door panel, the interference structure acts (for example, the convex portion of the second side surface portion and the sliding contact portion are in sliding contact), and the opening speed of the door panel is reduced. Therefore, it is possible to suppress the wobbling of the door panel immediately before reaching the pop-up state.

Hereinafter, the vehicle door 1 to which the door check device 40 according to the embodiment of the present invention is applied will be described (see FIGS. 1 and 7). The vehicle door 1 is attached to an entrance / exit provided on a side surface of the vehicle body V. The various directions in the following description represent the directions in which the vehicle door 1 (door panel 11) is closed. Although the present embodiment is an example in which the present invention is applied to the door on the right side of the vehicle body V, the present invention can also be applied to other doors.

The vehicle door 1 includes a door body 10 (see FIG. 1). The door body 10 includes a door panel 11 and a door frame 12. The door panel 11 is composed of an inner panel 11a (vehicle interior side panel) and an outer panel 11b (vehicle interior outer panel). The outer peripheral edges of the inner panel 11a and the outer panel 11b are joined to each other. The inner panel 11a and the outer panel 11b are press-molded in advance so that a space is formed between the inner panel 11a and the outer panel 11b in a state where the outer peripheral edges thereof are joined to each other. That is, the door panel 11 is a box-shaped part (or bag-shaped part). A door frame 12 as a window frame is attached to the upper part of the door panel 11.

The front end surface of the door panel 11 is assembled to the inner peripheral portion of the entrance / exit via a hinge (not shown). The door panel 11 rotates around the axis of the hinge to open and close the door panel 11 (see FIGS. 7 to 9). That is, as will be described in detail later, the door panel 11 is opened so that the rear end side of the door panel 11 protrudes to the outside of the vehicle interior from the state in which the door panel 11 is completely closed (fully closed state (FIG. 7)). It shifts to the open state (pop-up state (FIG. 8), half-open state and fully open state (FIG. 9)).

A door lock device 20, a door handle device 30, and a door check device 40 are attached to the door panel 11.

The door lock device 20 is arranged on the rear end surface in the door panel 11. The door lock device 20 includes a latch mechanism 21 that engages with a striker ST provided on the inner peripheral portion of the entrance / exit of the vehicle to hold the vehicle door 1 in a closed state (fully closed state). A part of the latch mechanism 21 is exposed in the opening provided on the rear end surface of the door panel 11. When the vehicle door 1 is closed, the striker ST enters the door panel 11 through this opening, and the latch mechanism 21 and the striker ST engage with each other.

The door lock device 20 includes a release mechanism 22 (opening mechanism) that releases the engagement between the latch mechanism 21 and the striker ST. The release mechanism 22 includes a lever, a link member, and the like that engage with the latch mechanism 21. Further, the door lock device 20 includes an electric actuator 23 (latch release actuator) that drives the release mechanism 22 (rotates or moves the lever, link member, or the like). The electric actuator 23 is connected to a vehicle control device via a wire harness (not shown). Further, the door lock device 20 includes a link mechanism 24 (for example, a rod RD extending in the vehicle height direction). The release mechanism 22 is connected to the door handle device 30 described later via the link mechanism 24. As will be described in detail later, the release mechanism 22 is usually driven by the electric actuator 23. If there is a problem with the electric parts such as the electric actuator 23, the control device, and the wire harness, the handle portion 31 (see FIG. 2) of the door handle device 30 is rotated, and the operating force thereof is applied to the link mechanism 24. The release mechanism 22 can be operated by mechanically transmitting the signal to the release mechanism 22 via the above.

Further, the door lock device 20 has a state in which the link mechanism 24 and the release mechanism 22 can be engaged (unlocked state) and a state in which the link mechanism 24 and the release mechanism 22 cannot be engaged (locked state). The locking mechanism 25 for switching the above is provided. In the unlocked state, the door handle device 30 can be used to operate the unlocking mechanism 22, but in the locked state, the door handle device 30 cannot be used to operate the unlocking mechanism 22. The locking mechanism 25 includes a key cylinder (not shown), and the key inserted into the key cylinder is rotated in a predetermined direction (locking direction or unlocking direction) to engage the link mechanism 24 and the unlocking mechanism 22. The state can be switched. Further, the door lock device 20 includes an electric actuator 26 (locking / unlocking couture) that drives the locking mechanism 25 to switch the engagement state between the link mechanism 24 and the unlocking mechanism 22. The electric actuator 26 is connected to a vehicle control device via a wire harness (not shown).

A recessed RP slightly recessed to the left side (inside the door panel 11) is formed in a portion located above the door lock device 20 at the rear portion of the outer panel 11b (see FIG. 2). A door handle device 30 is attached to this recessed RP.

As shown in FIG. 2, the door handle device 30 includes a handle portion 31, a touch sensor 32, and a push button type switch 33. The touch sensor 32 is, for example, a capacitance sensor that detects the capacitance or its change and outputs a signal according to the detection result.

The handle portion 31 is a substantially oval plate-shaped portion extending in the front-rear direction of the vehicle. The handle portion 31 is arranged in the recess RP so that the plate thickness direction thereof substantially coincides with the thickness direction (vehicle width direction) of the door panel 11. A shaft member (not shown) extending in the vehicle height direction is provided in the recess RP. A portion of the handle portion 31 located slightly forward of the central portion in the longitudinal direction is rotatably supported by the shaft member. The door handle device 30 has a spring (not shown) such that the front end portion and the rear end portion of the handle portion 31 are urged to the outside of the passenger compartment. In a normal state (a state in which the user does not touch the handle portion 31), both side surfaces are substantially the same without a step at the boundary between the outer side surface of the handle portion 31 and the outer side surface of the door panel 11. It is located in the plane. That is, the-handle portion 31 does not protrude from the door panel 11. When the user manually pushes the front end portion or the rear end portion of the handle portion 31 toward the vehicle interior side, the spring is elastically deformed and the handle portion 31 rotates slightly around the shaft member. When the user releases the handle portion 31, the elastic force of the spring causes the handle portion 31 to return to the normal state.

A touch sensor 32 is built in the front end portion of the handle portion 31. The touch sensor 32 outputs a signal corresponding to a change in the capacitance of the front end portion of the handle portion 31.

Further, a push button type switch 33 is attached to the rear end portion of the recess RP. When a user who intends to get into the vehicle pushes the rear end portion of the handle portion 31 by hand, the handle portion 31 rotates so that the rear end portion of the handle portion 31 slightly enters the vehicle interior side, and the handle portion 31 The surface on the vehicle interior side at the rear end abuts on the push button type switch 33. Then, the push button type switch 33 is pushed by the further rotation of the handle portion 31. That is, the push button type switch 33 changes from the off state to the on state. When the user releases the handle portion 31, the handle portion 31 returns to the normal state. That is, the handle portion 31 is separated from the push button type switch 33. As a result, the push button type switch 33 returns from the on state to the off state. The electric signal indicating the on / off of the push button type switch 33 corresponds to the trigger signal of the present invention.

The touch sensor 32 is connected to the control device via a wire harness (not shown). The output signal of the touch sensor 32 is supplied to the control device via the wire harness. Further, the push button type switch 33 is also connected to the control device via a wire harness (not shown). The control device detects the operation mode of the touch sensor 32 based on the output signal of the touch sensor 32. Further, the control device detects the on / off state of the push button type switch 33. The control device controls the electric actuator 23 and the electric actuator 26 based on the detection results.

Further, when the front end portion of the handle portion 31 is pushed toward the vehicle interior side, the handle portion 31 rotates so that the front end portion of the handle portion 31 enters the vehicle interior side. As a result, the rear end portion of the handle portion 31 projects relatively large to the outside of the vehicle interior, and the user can grasp the-handle portion 31 by hand. From this state, when the user grabs the handle portion 31 and pulls it toward the front, the handle portion 31 further rotates. Then, the front end portion of the handle portion 31 engages with the rod RD via a crank, a lever, etc. (not shown), and the rod RD is pushed downward. At this time, in the unlocked state, the operating force of the handle portion 31 is mechanically transmitted to the release mechanism 22, and the release mechanism 22 can be operated.

The door check device 40 holds the opening degree (opening angle) of the door panel 11 at a predetermined value. The door check device 40 includes a door check lever 41 and a shoe 42. The shoe 52 includes a pair of shoes 42U and 42L (see FIG. 3). The door check lever 41 is a long member. The cross section perpendicular to the longitudinal direction (central axis) of the door check lever 41 exhibits a rectangular shape. That is, the door chuck lever 41 is a substantially prismatic member. The side surface portions of the door check lever 41 in the longitudinal direction excluding both end surfaces are perpendicular to the first side surface portion consisting of a set of side surfaces facing in opposite directions and the side surfaces constituting the first side surface portion. And, it is composed of a second side surface portion composed of a set of side surfaces directed in opposite directions. The door check lever 41 is arranged in the door panel 11. In the door panel 11, the two side surfaces constituting the first side surface portion are directed upward and downward, respectively, and the two side surfaces constituting the second side surface portion are directed toward the inner panel 11a and the outer panel 11b, respectively. That is, the longitudinal direction of the door check lever 41 is perpendicular to the width direction of the door panel 11. That is, the longitudinal direction of the door check lever 41 coincides with the vehicle front-rear direction when the door panel 11 is closed. In the following description, the direction from one side surface constituting the first side surface portion to the other side surface is referred to as a thickness direction, and the direction from one side surface constituting the second side surface portion to the other side surface is referred to as a width direction. Call. Of the first side surface portions, the surface facing upward is called the upper surface, and the surface facing downward is called the lower surface. Of the second side surface portion, the surface facing the inner panel 11a is referred to as a left surface, and the surface facing the outer panel 11b is referred to as a right surface. The door check lever 41 is a connecting portion that extends forward from the front end of the main body portion 41a to which the shoes 42U and 42L, which will be described later, slide into contact with each other, and is connected to the inner peripheral portion of the entrance / exit via a hinge (not shown). It has 41b and. The main body portion 41a and the connecting portion 41b are integrally formed.

First recesses R1U, R1L, second recesses R2U, R2L, and third recesses R3U, R3L are formed on the upper surface and the lower surface of the main body 41a. These recesses are arranged at predetermined intervals in the longitudinal direction of the main body 41a. The first recesses R1U and R1L are arranged at the front end portion of the main body portion 41a. The second recesses R2U and R2L are arranged at the center of the main body 41a in the longitudinal direction. The third recesses R3U and R3L are arranged at the rear end of the main body 41a.

In general, as shown in FIG. 10, the conventional door door check lever CL is provided with recesses RCU, RCL and recesses RRU, RRL at substantially the center and rear ends in the longitudinal direction thereof, respectively, and the front ends thereof are provided with recesses RCU and RRL, respectively. No recess is provided. Further, the upper surface of the door check lever CL is gently inclined so that the rear portion is located above the front portion of the portion located in front of the concave RCU, and the lower surface of the door check lever CL is more than the concave RCL. It is gently inclined so that the rear part is located below the front part of the part located in the front part.

On the other hand, the door check lever 41 also has recesses R1U and R1L at the front end portion of the main body portion 41a (see FIG. 3). The configuration of the second recesses R2U, R2L and the third recesses R3U, R3L of the door check lever 41 is substantially the same as the configuration of the conventional door check lever CL, and is not directly related to the present invention. , These explanations will be omitted, and the configurations of the first recesses R1U and R1L will be described below.

The first recess R1U is composed of a front inclined surface SF _R1U and a rear inclined surface SR _R1U (see FIG. 5). The front inclined surface SF _R1U extends rearwardly and downwardly from the front end portion of the upper surface of the main body portion 41a. That is, the rear side is located below the front side of the front inclined surface SF _R1U. The rear inclined surface SR _R1U extends rearwardly and upwardly from the rear end (lower end) of the front inclined surface SF _R1U. That is, the rear side is located above the front side of the rear inclined surface SR _R1U. The front inclined surface SF _R1U and the rear inclined surface SR _R1U correspond to the first engaging slope and the second inclined surface of the present invention, respectively.

The first recess R1L and the first recess R1U have a symmetrical shape (vertical symmetrical shape) with respect to a plane that bisects the main body portion 41a in the thickness direction (vertical direction). That is, the first recess R1L is composed of a front inclined surface SF _R1L and a rear inclined surface SR _R1L . The front inclined surface SF _R1L extends rearwardly and upwardly from the front end portion of the lower surface of the main body portion 41a. That is, the rear portion is located above the front portion of the front inclined surface SF _R1L. The rear inclined surface SR _R1L extends rearwardly and downwardly from the rear end (upper end) of the front inclined surface SF _R1L. That is, the rear portion is located below the front portion of the rear _{inclined surface SR R1L.} The front inclined surface SF _R1L and the rear inclined surface SR _R1L correspond to the first engaging slope and the second inclined surface of the present invention, respectively.

The angle θ1 between the front inclined surface SF _R1U and the front inclined surface SF _R1L is larger than the angle θ2 between the _{rear inclined surface SR R1U} and the rear inclined surface SR _R1L. Further, as described above, recesses are formed on both sides of the main body portion 41a in the plate thickness direction. Therefore, the plate thickness of the main body 41a changes in the longitudinal direction of the main body 41a. The thickness d1 (distance between the deepest part of the first concave portion R1U and the deepest part of the first concave portion R1L) of the main body portion 41a where the first concave portion R1U and the first concave portion R1L are formed is the main body portion. Of 41a, the thickness d2 of the portion located between the first recesses R1U and R1L and the second recesses R2U and R2L is smaller. The thickness d2 is constant in the longitudinal direction of the main body 41a.

The shoes 42U and 42L are arranged above and below the door check lever 41 inside the door panel 11, respectively (see FIG. 3). The shoes 42U and 42L are fixed to the front end surface of the door panel 11. Since the shoe 42U and the shoe 42L have the same configuration and their mounting directions are only upside down, the configuration of the shoe 42U will be described below, and the description of the shoe 42L will be omitted.

The shoe 42U includes a case 421, a coil spring 422, and a pressor 423. The case 421 is a tubular member extending in the vehicle height direction. The case 421 accommodates the coil spring 422 described below and functions as a guide portion that regulates the moving direction of the presser 423 in the vehicle height direction. The coil spring 422 is arranged in the case 421 so that its central axis coincides with the vehicle height direction (the plate thickness direction of the main body 41a). The upper end of the coil spring 422 is fixed to the case 421. A presser 423 is connected to the lower end of the coil spring 422. The presser 423 is provided on the lower surface of the base portion 423a fixed to the lower surface of the coil spring 422 and the lower surface of the base portion 423a, and is a columnar convex portion extending in the width direction of the door check lever 41 (the direction perpendicular to the paper surface in FIG. 3). It has 423b.

An opening is provided on the front end surface of the door panel 11, and the front end portion of the door check lever 41 projects forward from this opening. The front end of the door check lever 41 is connected to the peripheral edge of the entrance / exit of the vehicle body V via a hinge (not shown).

The door check lever 41 is sandwiched between the presser 423 of the shoe 42U and the presser 423 of the shoe 42L. That is, with the coil spring 422 of the shoe 42U and the shoe 42L compressed, the convex portion 423b of the shoe 42U and the convex portion 423b of the shoe 42L are in contact with the upper surface and the lower surface of the door check lever 41, respectively.

When the door panel 11 is closed (fully closed state), the convex portion 423b of the shoe 42U and the convex portion 423b of the shoe 42L are in contact with the intermediate portions of the _{front inclined surface SF R1U} and the front inclined surface SF _{R1L, respectively.} (See Fig. 5). In this state, since the coil spring 422 of the shoe 42U and the coil spring 422 of the shoe 42L are compressed, the front inclined surface SF _R1U and the front inclined surface SF _R1L are pressed (pinched) downward and upward, respectively. .. As a result, the door check lever 41 is urged to be pushed forward from the opening OP. That is, the door panel 11 is urged in the opening direction (see FIG. 6). However, as described above, since the latch mechanism 21 and the striker ST are engaged, the door panel 11 does not open in this state. The thickness d0 of the intermediate portion between the front inclined surface SF _R1U and the front inclined surface SF _R1L , where the presser 423 of the shoe 42U and the convex portion 423b of the shoe 42L are in contact with each other in the fully closed state, is Greater than thickness d1 and smaller than thickness d2.

In addition, in a state where the conventional vehicle door to which the conventional door check lever CL is applied is closed, a pair of upper and lower shoes are located on the upper surface of the check lever CL in front of the concave RCU and the door. Of the lower surface of the check lever CL, the portion located in front of the concave RCL is pressed (pinching). As described above, of the upper surface of the conventional door check lever CL, the rear portion is gently inclined so as to be located above the front portion of the portion located in front of the concave RCU, and the lower surface of the door check lever CL is gently inclined. Of these, the rear portion is gently inclined so as to be located below the front portion of the portion located in front of the concave RCL. Therefore, in the state where the door panel is closed, the door check lever CL is urged by the shoe so as to be pulled into the door panel. That is, the door panel is urged in the closing direction (see FIG. 11).

When the user who intends to get into the vehicle pushes the rear end portion of the handle portion 31 by hand while the panel 11 is closed (see FIG. 7), the handle portion 31 rotates. As a result, the push button type switch 33 is pushed. When the control device detects that the push button type switch 33 is pressed (change from the off state to the on state), the control device determines the locking / unlocking state. When in the locked state, the control device operates the electric actuator 26 to shift from the locked state to the unlocked state. On the other hand, in the unlocked state, the control device maintains the unlocked state without operating the electric actuator 26. Next, the control device operates the electric actuator 23. That is, the release mechanism 22 is operated to release the engagement between the latch mechanism 21 and the striker ST. As described above, since the door panel 11 is urged in the opening direction by the door check device 40, when the engagement between the latch mechanism 21 and the striker ST is released, the door check lever 41 moves forward from the door panel 11. The door panel 11 begins to open. Then, the vehicle door 1 comes to rest in a state where the shoe 42U and the pressors 423 and 423 of the shoe 42L are fitted into the deepest portions of the first recesses R1U and R1L (see FIGS. 4 and 8). This state is called a pop-up state. In the pop-up state, the rear end portion of the vehicle interior outer surface of the door panel 11 projects from the outer surface of the vehicle body V.

On the other hand, in the pop-up state, the rear end portion of the vehicle interior side surface of the door panel 11 is located inside the side surface portion of the vehicle body V. Therefore, in the pop-up state, the user cannot get into the vehicle.

In the pop-up state, the user can further open the door panel 11 by touching the rear end portion of the door body 10 and pulling the portion outward. When the door panel 11 is further opened from the pop-up state, the door check lever 41 is pulled out further forward from the door panel 11. Then, the pressers 423 and 423 of the shoe 42U and the shoe 42L separate from the first recesses R1U and R1L and fit into the second recesses R2U and R2L. This state is called a half-open state. When the door panel 11 is further opened from the half-open state, the door check lever 41 is pulled out further forward from the door panel 11. Then, the pressers 423 and 423 of the shoe 42U and the shoe 42L are separated from the first recesses R2U and R2L and fitted into the third recesses R3U and R3L, and the vehicle door 1 cannot be opened any more. This state is called a fully open state (see FIG. 9).

Here, in a state where a defect has occurred in an electric component such as the electric actuator 23, the control device, or the wire harness, the electric actuator 23 may not be able to operate even if the push button type switch 33 is pressed. That is, the engagement between the latch mechanism 21 and the striker ST may not be released by using the electric actuator 23. In such a case, the user-pushes the front end of the handle 31 toward the vehicle interior side, projects the rear end of the handle 31 toward the outside of the vehicle, and-holds the handle 31 by hand and moves it toward the front. Pull. At that time, in the unlocked state, the operating force applied to the handle portion 31 can be mechanically transmitted to the release mechanism 22 to operate the release mechanism 22. As a result, the engagement between the latch mechanism 21 and the striker ST is released, and the vehicle door 1 shifts from the fully closed state to the pop-up state. In the locked state, the key may be inserted into the key cylinder and the key may be rotated in a predetermined direction to shift from the locked state to the unlocked state. If there is a problem with the electric actuator 23 (latch release actuator) but there is no problem with the electric actuator 26 (locking / unlocking actuator) and the control device, the user can touch the front end of the handle 31. It is possible to shift from the locked state to the unlocked state. In this case, it is not necessary to use the key.

As described above, in the fully closed state, the door panel 11 is opened by pressing (pinching) _{the front inclined surfaces SF R1U} and SF _R1L of the first recesses R1U and R1L of the door check lever 41 with the pressers 423 and 423. It is urging in the direction. Therefore, according to the present embodiment, it is not necessary to provide an urging device (electric actuator, spring, etc.) for shifting from the fully closed state to the pop-up state separately from the door check device 40. Therefore, according to the present embodiment, the number of parts is smaller than that in the case where the urging device as described above is provided.

In addition, the door panel 11 shifts from the fully closed state to the pop-up state by one action of the user. That is, when the user simply pushes the rear end of the handle portion 31, the electric actuator 23 disengages the latch mechanism 21 from the striker ST, and the door panel 11 opens slightly from the fully closed state to the pop-up state. Transition. In the locked state, the electric actuator 26 shifts from the locked state to the unlocked state before the latch mechanism 21 and the striker ST are disengaged by the electric actuator 23).

Further, even if there is a problem with electric parts such as the electric actuator 23, the electric actuator 26, the control device, and the wire harness, the lock mechanism 25 is mechanically operated by using the key to enter the unlocked state. It can be shifted, and-using the handle portion 31, the release mechanism 22 is mechanically driven to disengage the latch mechanism 21 from the striker ST, shift to the pop-up state, and open the door panel 11. be able to.

Furthermore, the practice of the present invention is not limited to the above-described embodiment, and various modifications can be made as long as the object of the present invention is not deviated.

For example, instead of the door check device 40, the door check device 50 shown in FIG. 13 may be adopted. The door check device 50 includes a door check lever 51 shown in FIG. The door check lever 51 has a connecting portion 51a and a main body portion 51b, similarly to the door check lever 41. Further, the main body 51b is provided with the same first recesses R1U, R1L, second recesses R2U, R2L, and third recesses R3U, R3L as the main body 41b, and is provided with fourth recesses R4U, R4L. There is. The width of the main body 41b of the door check lever 41 is substantially constant in the longitudinal direction of the main body 41b (extending direction of the central axis), whereas the width W of the main body 51b of the door check lever 51 is the main body. It changes in the longitudinal direction of 51b.

Specifically, the width of the portion of the main body portion 51b in which the first recesses R1U and R1L are formed is set to be slightly larger than the other portions. More specifically, the boundary portion BD between the front half portion and the rear half portion of the first recesses R1U and R1L (the portion where the front inclined surface SF _R1U and the front inclined surface SF _R1L are formed, the rear inclined surface SR _R1U and the rear). The width W of the main body portion 51b gradually increases from the portion P1 located slightly forward of the side inclined surface SR _{R1L (the boundary with the portion where the side inclined surface SR R1L is formed) toward the rear, and becomes maximum at the boundary portion BD.} .. The width W of the main body 51b gradually decreases from the boundary BD toward the rear, and the width W of the main body 51b becomes equal to the width W of the portion P1 at the portion P2 located behind the boundary BD. It has become. _{In other words, the convex portions P 51b} and P _51b are formed on the second side surface portion of the main body portion 51b where the first concave portions R1U and R1L are formed. The position of the top of the convex portion P _51b (the position in the longitudinal direction of the main body portion 51b) and the position of the boundary portion BD coincide with each other. Further, the inclination angle α of the latter half of the convex portion P _51b is set to be smaller than the inclination angle β of the first half (see FIG. 15). The width W of the portion located in front of the portion P1 and the portion located behind the portion P2 is constant.

Further, the shoe 42 includes convex portions P ₄₂ and P _{42 arranged to face} the convex portions P 51b and P _51b . The convex portions P ₄₂ and P ₄₂ are made of an elastic material (for example, a synthetic resin material). The distance between the tops of the convex portions P ₄₂ and P ₄₂ is substantially the same as the width W of the portion of the check lever 51b located in front of the portion P1 and the portion located behind the portion P2.

Similar to the example in which the door check lever 41 is adopted, when the engagement between the latch mechanism 21 and the striker ST is released, the door check lever 41 is pushed forward from the door panel 11, and the door panel 11 starts to open and pops up. To reach. At the first stage of the process, the convex portions P ₄₂ , P ₄₂ and the second side surface portion of the door check lever 51 hardly interfere with each other. Eventually, the convex portions P _51b and P _51b and the convex portions P ₄₂ and P ₄₂ begin to interfere with each other (see FIG. 13 (A)). That is, the convex portions P _51b and P _51b and the convex portions P ₄₂ and P ₄₂ start to be in sliding contact with each other. In this process, the convex portions P ₄₂ and P ₄₂ are slightly elastically deformed. As a result, the opening speed of the door panel 11 is reduced just before the door panel 11 reaches the pop-up state (see FIG. 16A).

In the example in which the door check lever 41 is adopted, since the interference structure (deceleration mechanism) as described above is not provided, the door panel 11 wobbles when it reaches the pop-up state (see FIG. 16 (B)). _{That is, the pressers 423} and 423 of the shoe 42U and the shoe 42L exceed the deepest portion of the first recesses R1U and R1L from the front inclined surface SF R1U and the front inclined surface SF _R1L , and the rear inclined surface SR R1U and the rear _{inclined surface SR R1U.} It approaches the surface SR _R1L a little and goes to the deepest part of the first recesses R1U and R1L again. On the other hand, in the example in which the door check device 50 is adopted, the opening speed of the door panel 11 is reduced immediately before the door panel 11 reaches the pop-up state, so that the above-mentioned wobbling of the door panel 11 can be suppressed.

When the door panel 11 is further opened from the pop-up state, the convex portions P _51b and P _51b get over the convex portions P ₄₂ and P ₄₂ (see FIG. 13B). Therefore, the convex portions P ₄₂ and P ₄₂ and the second side surface portion of the door check lever 51 hardly interfere with each other. On the other hand, on the way from the fully open state to the fully closed state, the convex portions P _51b and P _51b interfere with the convex portions P ₄₂ and P _42. However, as described above, since _{the inclination angle of the latter half of the convex portion P 51b} is set to be smaller than the inclination angle of the first half, the change in the closing speed of the door panel 11 is relatively gradual, and the user can use the door panel 11 It does not easily affect the feeling of closing.

The positions of the convex portions P _51b and P _51b are not limited to the above-mentioned form. For example, the vertices of the convex portions P _51b and P _51b may be located slightly anterior to or slightly posterior to the boundary BD. Further, not only in the vicinity of the first recesses R1U and R1L, but also in the vicinity of any or all of the second recesses R2U, R2L, the third recesses R3U, R3L and the fourth recesses R4U, R4L. Parts P _51b and P _51b may be provided.

For example, instead of the push button switch 33 of the above embodiment, the same touch sensor 33A as the touch sensor 32 may be used (see FIG. 12). In this case, as shown in the figure, the touch sensor 33A may be built in the rear end portion of the handle portion 31.

Further, for example, the magnitude relationship of the angle θ1, the angle θ2, the thickness d0, the thickness d1, and the thickness d2 is an example, and is not limited to the above embodiment. For example, in order to set a relatively large force (pop-up force) for urging the door panel 11 in the fully closed state, the thickness d0 is set relatively large and the coil spring 422 is relatively largely compressed. It is advisable to set the spring force relatively large. Further, the angle θ1 may be set relatively large. However, in these cases, the force required to close the door panel 11 becomes relatively large. Further, in order to set the opening degree (opening angle or protrusion amount) of the door panel 11 in the pop-up state to be relatively large, it is preferable to set the difference between the thickness d0 and the thickness d1 to be relatively large. In order to suppress the runout (wobble) of the door panel 11 when the door panel 11 shifts from the fully closed state to the pop-up state, it is preferable to set the angle θ2 relatively large.

When the door panel 11 is closed from the fully open state, the door check lever 41 is pulled into the door panel 11. At that time, the convex portion 23b of the shoe 42U and the shoe 42L _abuts on the rear inclined surface SR R1U and the rear inclined surface SR _R1L , respectively, and presses (pinches) them. As a result, the door check lever 41 is urged to be pulled into the door panel 11. That is, the door panel 11 is urged in the closing direction. In order to set the force for urging the door panel 11 in the closing direction to be relatively large (to reduce the user's operating force), the thickness d2 is set to be relatively large, and the coil spring 422 is relatively largely compressed. It is advisable to set the spring force relatively large.

In the above embodiment, a push button type switch 33 and a touch sensor 32 are adopted as devices for outputting (generating) a trigger signal for operating the electric actuator 23 and the electric actuator 26. These devices have the above-described embodiment. However, other types of switches and sensors may be adopted.

Further, the opening degree (opening angle) of the door panel 11 in the pop-up state is not limited to the above embodiment, and can be set to any value. Further, the amount of protrusion of the door panel 11 in the pop-up state is not limited to the above embodiment, and can be set to any value. For example, the rear part of the door panel 11 may be touched and set to a value small enough to allow the outside of the door panel 11 to be pulled. However, this protrusion amount is preferably equal to or less than the thickness dimension of the door panel 11.

Further, in the above embodiment, the handle portion 31 is rotatably supported around a rotation shaft extending in the vehicle height direction, but the grip portion 31 is rotatably supported around the rotation shaft extending in the vehicle front-rear direction. It may be rotatably supported.

Further, for example, horizontal portions may be provided between _{the front inclined surface SF R1U} and the rear inclined surface SR _R1U, and between the front inclined surface SF _R1L and the rear inclined surface SR _{R1L, respectively.}
