  The present invention relates to a vehicle door.

The vehicle door is provided with a side impact beam for the purpose of protecting an occupant from the other vehicle when the other vehicle collides sideways (see, for example, Patent Document 1). The side impact beam can absorb and disperse the energy received at the time of a side collision by transmitting a collision load applied when another vehicle collides to a side to a vehicle skeleton such as a pillar. Generally, the side impact beam has a cylindrical pipe extending in the front-rear direction of the vehicle, and brackets provided at both ends of the pipe and coupled to the vehicle door.

  However, since the side impact beam supports a collision load at both ends at the time of a side collision, a bending moment may be generated in the side impact beam, and the side impact beam may be bent. When the side impact beam is bent, the magnitude of the collision load that can be supported is extremely reduced. In order to suppress the bending of the side impact beam, reinforcement of the side impact beam can be considered, but it has been difficult to reinforce the side impact beam without hindering the raising and lowering of the door glass.

As a result, the magnitude of the bending moment generated in the side impact beam is reduced by the tensile load of the inner panel, and the side impact beam can be prevented from being bent. Therefore, according to the first vehicle door, the strength against a collision load applied to the outer panel at the time of a side collision of the vehicle can be enhanced without hindering the raising and lowering of the door glass.

  The first vehicle door includes an electric motor that raises and lowers the door glass, a sensor that detects an object on the side of the vehicle, a determination unit that determines the possibility of a side collision by the object based on a signal from the sensor, When it is determined by the determination means that there is a possibility of a side collision, it is preferable to further include a drive means for driving the electric motor so that the support member is adjacent to the side impact beam in the vehicle width direction. .

  According to this configuration, an object on the side of the vehicle is detected by the sensor, and the possibility of a side collision by the object is determined by the determination unit. When it is determined by this determination means that there is a possibility of a side collision, the electric motor is driven by the drive means, the support member is raised and lowered together with the door glass, and the support member and the side impact beam are moved in the vehicle width direction. Can be next to each other. Therefore, according to this configuration, it is possible to reinforce the strength against the collision load applied to the outer panel in the case of a side collision of the vehicle without depending on the lifted state of the door glass.

  The second vehicle door of the present invention extends in the front-rear direction of the vehicle, and both end portions thereof are continuous with the first portion adjacent to the vehicle skeleton member in the vehicle width direction, and the first portion. And a reinforcing member having a second portion extending in the vehicle width direction. The reinforcing member is coupled to the lower side of the door glass and is provided between the outer panel and the inner panel. It is characterized by having.

  According to the second vehicle door, the reinforcing member is provided between the outer panel and the inner panel, and both end portions of the first portion extending in the front-rear direction of the vehicle are respectively connected to the vehicle skeleton member and the vehicle width. Since they are adjacent to each other in the direction, the collision load can be supported by the tensile load generated in the first portion.

  Further, since the reinforcing member has a second portion that is continuous with the first portion and extends in the vehicle width direction, the tensile load generated in the inner panel is applied to the first portion via the second portion. Reportedly. Therefore, the magnitude of the bending moment generated in the first portion is reduced by the tensile load of the inner panel, and the first portion can be prevented from being bent. According to the second vehicle door, since the reinforcing member is coupled to the door glass, the reinforcing member can be raised and lowered together with the door glass. Therefore, according to the second vehicle door, the strength against the collision load applied to the outer panel in the case of a side collision of the vehicle can be enhanced without hindering the raising and lowering of the door glass.

(First embodiment)

  First, the configuration of the vehicle door according to the first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a view of a vehicle door according to a first embodiment of the present invention as viewed from the inner surface side. In FIG. 1, in order to make the characteristic part of this embodiment easy to see, the inner panel is not shown, and a circuit block diagram of the electric system section is shown. 2 is an end view of the vehicle door taken along line II-II in FIG. 1, and FIG. 3 is an end view of the vehicle door taken along line III-III in FIG.

  1 to 3 includes an outer panel 2, a door frame 3, a door glass 4, an inner panel 5, a side impact beam 6, a support member 7, a load receiving member 8, a radar sensor 9, and a window sensor 10. An electronic control unit (hereinafter referred to as an ECU: Electrical Control Unit) 11 and a window electric motor 12 are provided. Note that the radar sensor 9, the window sensor 10, and the ECU 11 constitute an electric system section.

  The outer panel 2 forms the outer surface of the vehicle door 1 and constitutes a part of the vehicle body. A door frame 3 is provided on the upper portion of the outer panel 2. The outer panel 2 and the door frame 3 cover the outer edge of the door glass 4 when the window is closed.

  An inner panel 5 is provided on the inner surface side of the outer panel 2. An outer edge portion of the inner panel 5 is coupled to the outer panel 2, and a portion other than the outer edge portion of the inner panel 5 is separated from the outer panel 2. A side impact beam 6 is provided between the outer panel 2 and the inner panel 5.

  The side impact beam 6 extends in the front-rear direction of the vehicle. For example, both ends of the side impact beam 6 are coupled to the inner panel 5. Specifically, the side impact beam 6 includes a pipe 6a and brackets 6b and 6c. The pipe 6a has a cylindrical shape and extends in the front-rear direction of the vehicle. A bracket 6b is coupled to one end of the pipe 6a, and the bracket 6b is coupled to the inner panel 5, for example. A bracket 6c is coupled to the other end of the pipe 6a, and the bracket 6c is coupled to the inner panel 5, for example. These coupling methods may be welding, for example. A support member 7 is provided between the pipe 6 a of the side impact beam 6 and the inner panel 5.

  The support member 7 is a substantially rectangular parallelepiped member. The upper surface 7a of the support member 7 in the vehicle height direction is coupled to the door glass support member 14 via the spacer 13 by, for example, welding. The door glass support member 14 is coupled to the lower edge of the door glass 4 and supports the door glass 4. That is, the support member 7 is coupled to the door glass 4 so as to be separated from the door glass 4 and can be moved up and down as the door glass 4 is moved up and down.

  The surface 7b on one side of the support member 7 in the vehicle width direction is adjacent to the side impact beam 6 in the vehicle width direction when the window is closed. Protrusions 7c and 7d are respectively provided on the upper and lower portions of the surface 7b of the support member 7 in the vehicle height direction. The protrusions 7c and 7d act so as to guide the side impact beam 6 to the surface 7b of the support member 7 when the side impact beam 6 is deformed by a collision load.

  The other surface 7e in the vehicle width direction of the support member 7 is adjacent to the load receiving member 8 in the vehicle width direction in a state where the window is closed. The load receiving member 8 is a substantially rectangular parallelepiped member. The load receiving member 8 is coupled to the inner panel 5 by welding, for example.

  The support member 7 and the load receiving member 8 are preferably provided at the center in the longitudinal direction of the side impact beam 6. This is because only the both ends of the side impact beam 6 are coupled, and therefore, the magnitude of the bending moment generated in the side impact beam 6 is the largest in the central portion in the longitudinal direction of the side impact beam 6. For the support member 7 and the load receiving member 8, for example, a material such as metal or resin is used.

  Next, the structure of the electrical system part of the vehicle door 1 of the first embodiment will be described. The radar sensor 9 is, for example, a millimeter wave radar sensor such as a pre-crash sensor. The radar sensor 9 is attached to, for example, a bumper, a door mirror, or a room mirror in the vehicle. The radar sensor 9 transmits a millimeter wave signal to a predetermined range on the side surface of the vehicle, receives a reflected wave signal reflected by the object, and detects the presence or absence of the object on the side surface of the vehicle. . The radar sensor 9 detects the distance to the object from the millimeter wave signal transmission time and the reflected wave signal reception time. Further, the radar sensor 9 detects the relative speed with respect to the object by detecting the distance to the object a plurality of times at predetermined time intervals. The radar sensor 9 outputs to the ECU 11 a distance signal having a value corresponding to the detected distance to the object and a speed signal having a value corresponding to the relative speed with the object.

  The window sensor 10 is a sensor for detecting the position of the support member 7 with respect to the side impact beam 6 by detecting the amount of elevation of the door glass 4. The window sensor 10 is provided between the outer panel 2 and the inner panel 5, for example. Specifically, the window sensor 10 detects the amount of elevation of the door glass 4 by detecting the amount and direction of rotation of a window electric motor 12 described later. The window sensor 10 outputs a lift amount signal having a value corresponding to the detected lift amount of the door glass 4 to the ECU 11.

  The ECU 11 includes a microprocessor that performs calculations, a ROM that stores programs for causing the microprocessor to execute each process, a RAM that stores various data such as calculation results, and a backup RAM in which the stored contents are held by a 12V battery. Etc. With this configuration, the ECU 11 includes the first determination unit 11a, the second determination unit 11b, and the drive unit 11c.

  The first determination unit 11a determines the possibility of a side collision by an object based on the distance signal and the speed signal received from the radar sensor 9. That is, the 1st determination part 11a functions as a determination means of this invention. When there is a possibility of a side collision, the first determination unit 11a outputs the determination result information to the second determination unit 11b.

  When the second determination unit 11b receives the determination result information from the first determination unit 11a, the support member 7 is adjacent to the side impact beam 6 in the vehicle width direction based on the lift amount signal received from the window sensor 10. It is determined whether or not. Specifically, the 2nd determination part 11b determines whether the window is closed from the raising / lowering amount of the door glass 4 according to the raising / lowering amount signal. When the window is not closed, the second determination unit 11b outputs the determination result information to the drive unit 11c.

  Upon receiving the determination result information from the second determination unit 11b, the drive unit 11c instructs the window electric motor 12 to place the support member 7 adjacent to the side impact beam 6 in the vehicle width direction. Specifically, the drive unit 11c instructs the window electric motor 12 to close the window. That is, the drive part 11c functions as the drive means of the present invention.

  The window electric motor 12 transmits driving force to the window regulator 15 based on a command from the ECU 11 to move the door glass 4 up and down. For example, an X arm type window regulator or a wire type window regulator can be applied to the window regulator 15. For example, the window electric motor 12 and the ECU 11 are assembled into an ASSY by being combined, and are attached between the outer panel 2 and the inner panel 5.

  Next, the operation of the vehicle door 1 according to the first embodiment will be described. First, the radar sensor 9 detects whether or not there is an object on the side surface of the vehicle, the distance to the object, and the relative speed with the object, and a distance signal and object having values corresponding to the distance to the object A speed signal having a value corresponding to the relative speed is output to the first determination unit 11a of the ECU 11. Further, the window sensor 10 detects the lift amount of the door glass 4 and outputs a lift amount signal having a value corresponding to the lift amount to the second determination unit 11 b of the ECU 11.

  FIG. 4 is a flowchart showing the operation of the ECU 11. First, the first determination unit 11a determines the possibility of a side collision by an object based on the distance signal and the speed signal received from the radar sensor 9 (step S1).

  Next, when it is determined in step S <b> 1 that there is a possibility of a side collision, the support member 7 is connected to the side impact beam 6 and the vehicle based on the lift signal received by the second determination unit 11 b from the window sensor 10. It is determined whether or not they are adjacent in the width direction (step S2).

  Next, when it is determined in step S2 that the support member 7 is not adjacent to the side impact beam 6 in the vehicle width direction, the drive unit 11c drives the window electric motor 12 and closes the window. That is, the door glass 4 and the support member 7 are raised by the window electric motor 12. In this way, the support member 7 is arranged so that the support member 7 is adjacent to the side impact beam 6 in the vehicle width direction (step S3).

  When it is determined in step S1 that there is no possibility of a side collision, the first determination unit 11a does not output the determination result information to the second determination unit 11b. As a result, the ECU 11 performs steps S2, The process shown in FIG. 4 is terminated without executing the process of S3. When it is determined in step S2 that the support member 7 is adjacent to the side impact beam 6 in the vehicle width direction, the second determination unit 11b does not output the determination result information to the drive unit 11c. As a result, the ECU 11 ends the process shown in FIG. 4 without executing the process of step S3.

  Next, a collision load input to the vehicle door 1 and a tensile load generated in the vehicle door 1 at the time of a side collision will be described. FIG. 5 is a diagram for explaining a collision load input to the vehicle door shown in FIG. 2 and a tensile load generated in the vehicle door, and FIG. 6 shows a conventional vehicle door corresponding to FIG. It is a figure for demonstrating the input collision load and the tensile load which generate | occur | produces in the conventional vehicle door.

  First, a conventional vehicle door 20 that does not have the support member 7, the load receiving member 8, the spacer 13, and the electrical system (radar sensor 9, window sensor 10, and ECU 11) will be described with reference to FIG. . When a collision load Fa is applied to the outer panel 2 of the conventional vehicle door 20 during a vehicle side collision, the collision load Fa is transmitted to the side impact beam 6 through the outer panel 2. Since the brackets 6 b and 6 c of the side impact beam 6 are coupled to the inner panel 5, that is, because both ends of the side impact beam 6 are coupled to the inner panel 5, the side impact beam 6 has a tensile load Fb. appear. The side impact beam 6 supports the collision load Fa by this tensile load Fb.

  Here, since both ends of the side impact beam 6 are coupled to the inner panel 5, a bending moment having a magnitude corresponding to the magnitude of the collision load Fa is generated in the side impact beam 6. As shown in FIG. 6, the magnitude of this bending moment is maximized at the central portion in the longitudinal direction of the side impact beam 6 and decreases toward both ends of the side impact beam 6.

  Therefore, when the magnitude of the collision load Fa and the magnitude of the bending moment are increased, the impact load Fa cannot be supported by the tensile load Fb of the side impact beam 6, and the vicinity of the center of the side impact beam 6 in the longitudinal direction is bent. When the side impact beam 6 is bent, the magnitude of the tensile load Fb is reduced, and the magnitude of the collision load Fa that can be supported is extremely reduced.

  Next, the vehicle door 1 according to the present embodiment will be described with reference to FIG. Similar to the conventional vehicle door 20, when a collision load Fa is applied from an object to the outer panel 2 of the vehicle door 1 in the case of a side collision of the vehicle, the collision load Fa is applied to the side impact via the outer panel 2. This is transmitted to the beam 6 and a tensile load Fb is generated in the side impact beam 6. Further, the collision load Fa is transmitted to the inner panel 5 through the support member 7 and the load receiving member 8, and a tensile load Fc is also generated in the inner panel 5. Then, a reaction force Fd having a magnitude corresponding to the magnitude of the tensile load Fc is transmitted to the side impact beam 6 via the support member 7.

  As a result, as shown in FIG. 5, the magnitude of the bending moment generated in the side impact beam 6 is reduced from the dotted line to the solid line by the magnitude of the reaction force Fd. Therefore, even if the magnitude of the collision load Fa and the magnitude of the bending moment are further increased, the side impact beam 6 is suppressed from being bent.

  Therefore, according to the vehicle door 1 of the present embodiment, it is possible to enhance the strength against the collision load Fa applied to the outer panel 2 at the time of a side collision of the vehicle without hindering the raising and lowering of the door glass 4. Become.

Further, according to the vehicle door 1 of the present invention, when there is a possibility of a side collision by the radar sensor 9, the window sensor 10, the ECU 11, and the window electric motor 12, the support member 7 and the side impact beam 6 are connected to the vehicle. Adjacent to each other in the width direction. Therefore, according to the vehicle door 1 of the present embodiment, the strength against the collision load Fa applied to the outer panel 2 in the case of a side collision of the vehicle can be enhanced without depending on the lifted state of the door glass 4. It becomes possible.
(Second Embodiment)

  Next, the structure of the vehicle door according to the second embodiment of the present invention will be described with reference to FIGS. FIG. 7 is a view of the vehicle door according to the second embodiment of the present invention as viewed from the inner surface side. In FIG. 7, in order to make the characteristic part of this embodiment easy to see, the description of the inner panel is omitted, and a circuit block diagram of the electric system section is described. 8 and 9 are end views of the vehicle door taken along line VIII-VIII in FIG. FIG. 8 shows the vehicle door 1 </ b> A with the window closed, and FIG. 9 shows the vehicle door 1 </ b> A in a state ready for a side collision.

  The vehicle door 1 </ b> A shown in FIGS. 7 and 8 is a first embodiment in which the support member 7 is coupled to the door glass support member 14 without the spacer 13 and includes the ECU 11 </ b> A instead of the ECU 11. It differs from the vehicle door 1 of the form. Since the other configuration of the vehicle door 1A is the same as that of the vehicle door 1, the description thereof is omitted here.

  The upper surface 7a in the vehicle height direction of the support member 7 is joined to the door glass support member 14 without welding the spacer 13, for example, by welding. That is, the support member 7 is coupled adjacent to the door glass 4, and can be moved up and down as the door glass 4 moves up and down. Therefore, as shown in FIG. 9, when the window is opened by a predetermined amount, the surface 7b on one side in the vehicle width direction of the support member 7 is adjacent to the side impact beam 6 in the vehicle width direction, and the vehicle width of the support member 7 The other surface 7e in the direction is adjacent to the load receiving member 8 in the vehicle width direction.

  The ECU 11A is different from the ECU 11 in a configuration including a second determination unit 11d and a drive unit 11e, respectively, instead of the second determination unit 11b and the drive unit 11c. Since the first determination unit 11a of the ECU 11A is the same as the ECU 11, the description thereof is omitted here.

  When the second determination unit 11d receives the determination result information from the first determination unit 11a, the support member 7 is adjacent to the side impact beam 6 in the vehicle width direction based on the lift amount signal received from the window sensor 10. It is determined whether or not. Specifically, the second determination unit 11d stores in advance a predetermined lift amount of the door glass 4 when the support member 7 is adjacent to the side impact beam 6 in the vehicle width direction. The second determination unit 11d compares the lift amount corresponding to the lift amount signal from the window sensor 10 with a predetermined lift amount stored in advance, so that the support member 7 moves in the vehicle width direction with the side impact beam 6. It is determined whether or not they are next to each other. When the support member 7 is not adjacent to the side impact beam 6 in the vehicle width direction, the second determination unit 11d outputs the determination result information, the lift amount signal, and the predetermined lift amount to the drive unit 11e (Step S11). S2).

  When receiving the determination result information from the second determination unit 11d, the drive unit 11e instructs the window electric motor 12 so that the support member 7 is adjacent to the side impact beam 6 in the vehicle width direction. Specifically, the drive unit 11e obtains a difference between a lift amount corresponding to the lift amount signal and a predetermined lift amount, and raises and lowers the door glass 4 according to the difference polarity and value. 12 (step S3). That is, the drive unit 11e functions as the drive unit of the present invention.

Thus, even in the vehicle door 1A of the present embodiment, when the support member 7 is coupled to the door glass 4 and there is a possibility of a side collision, the radar sensor 9, the window sensor 10, the ECU 11A, and the window electric motor. Since the support member 7 is moved up and down by 12 so as to be adjacent to the side impact beam 6 in the vehicle width direction, the same advantages as the vehicle door 1 of the first embodiment can be obtained.
(Third embodiment)

  Next, the configuration of the vehicle door according to the third embodiment of the present invention will be described with reference to FIGS. FIG. 10 is a view of the vehicle door according to the third embodiment of the present invention as viewed from the inner surface side. In FIG. 10, in order to make the characteristic part of this embodiment easy to see, the description of the inner panel is omitted, and a circuit block diagram of the electric system section is described. 11 is an end view of the vehicle door taken along the line XI-XI in FIG. 10, and FIG. 12 is an end view of the vehicle door taken along the line XII-XII in FIG.

  The vehicle door 1B shown in FIGS. 10 to 12 includes a reinforcing member 16 instead of the side impact beam 6, the support member 7, and the load receiving member 8, and includes an ECU 11B instead of the ECU 11. It is different from the vehicle door 1 of the first embodiment. Since the other structure of the vehicle door 1B is the same as the vehicle door 1, description is abbreviate | omitted here.

  The reinforcing member 16 is provided between the outer panel 2 and the inner panel 5, and has a first portion 16a and a second portion 16b. The first portion 16a has, for example, a substantially rectangular parallelepiped shape and extends in the front-rear direction of the vehicle. Both end portions 16c and 16d of the first portion 16a are adjacent to the vehicle skeleton member in the vehicle width direction. On the other hand, the second portion 16b is continuous with the central portion in the vehicle width direction on the inner surface side of the first portion 16a. The second portion 16b has a substantially rectangular parallelepiped shape and extends in the vehicle width direction.

  An upper surface 16 e in the vehicle height direction of the reinforcing member 16 is coupled to the door glass support member 14 via the spacer 13. In other words, the reinforcing member 16 is coupled to the door glass 4 so as to be separated from the door glass 4 and can be moved up and down as the door glass 4 is moved up and down. Therefore, the reinforcing member 16 is disposed at a predetermined position in the vehicle height direction in a state where the window is closed. Specifically, the reinforcing member 16 is disposed at a bumper position in the vehicle in a state where the window is closed. The position of the bumper in the vehicle is about 400 mm to 500 mm from the ground contact surface.

  The ECU 11B is different from the ECU 11 of the first embodiment in a configuration including a second determination unit 11f and a drive unit 11g instead of the second determination unit 11b and the drive unit 11c. Since the first determination unit 11a of the ECU 11B is the same as the ECU 11, the description thereof is omitted here.

  When the second determination unit 11f receives the determination result information from the first determination unit 11a, the second determination unit 11f determines whether the reinforcing member 16 is disposed at a predetermined position based on the lift amount signal received from the window sensor 10. To do. Specifically, the 2nd determination part 11f determines whether the window is closed from the raising / lowering amount of the door glass 4 according to the raising / lowering amount signal. When the window is not closed, the second determination unit 11f outputs the determination result information to the drive unit 11g.

  Upon receiving the determination result information from the second determination unit 11f, the drive unit 11g instructs the window electric motor 12 to arrange the reinforcing member 16 at a predetermined position. Specifically, the drive unit 11g instructs the window electric motor 12 to close the window. That is, the drive unit 11g functions as the drive unit of the present invention.

  Next, the operation of the vehicle door 1B according to the third embodiment will be described. Since the operations of the radar sensor 9 and the window sensor 10 are as described above, description thereof is omitted here.

  FIG. 13 is a flowchart showing the operation of the ECU 11B. First, the first determination unit 11a determines the possibility of a side collision by an object based on the distance signal and the speed signal received from the radar sensor 9 (step S1).

  Next, when it is determined in step S <b> 1 that there is a possibility of a side collision, the reinforcing member 16 is disposed at a predetermined position based on the lift signal received by the second determination unit 11 f from the window sensor 10. It is determined whether or not (step S4).

  Next, when it is determined in step S4 that the reinforcing member 16 is not disposed at a predetermined position, the drive unit 11g drives the window electric motor 12 to close the window. That is, the door glass 4 and the reinforcing member 16 are raised by the window electric motor 12. In this way, the reinforcing member 16 is arranged at a predetermined position (step S5).

  When it is determined in step S1 that there is no possibility of a side collision, the first determination unit 11a does not output the determination result information to the second determination unit 11f, and as a result, the ECU 11B performs step S4, The process shown in FIG. 13 is terminated without executing the process of S5. When it is determined in step S4 that the reinforcing member 16 is disposed at a predetermined position, the second determination unit 11f does not output determination result information to the drive unit 11g, and as a result, the ECU 11B The process shown in FIG. 13 is terminated without executing the process of S5.

  Next, a collision load input to the vehicle door 1B and a tensile load generated in the vehicle door 1B during a side collision will be described. FIG. 14 is a diagram for explaining a collision load input to the vehicle door shown in FIG. 11 and a tensile load generated in the vehicle door.

  When a collision load Fa is applied from an object to the outer panel 2 of the vehicle door 1 during a side collision of the vehicle, the collision load Fa is transmitted to the first portion 16a of the reinforcing member 16 via the outer panel 2. . Since both ends of the first portion 16a are adjacent to the vehicle skeleton member in the vehicle width direction, a tensile load Fb is generated in the first portion 16a. The first portion 16a supports the collision load Fa by the tensile load Fb.

  Further, the collision load Fa is transmitted to the inner panel 5 through the second portion 16b, and the tensile load Fc is also generated in the inner panel 5. Then, a reaction force Fd having a magnitude corresponding to the magnitude of the tensile load Fc is transmitted to the first portion 16a via the second portion 16b. As a result, as shown in FIG. 14, the magnitude of the bending moment generated in the first portion 16a is reduced from the dotted line to the solid line by the magnitude of the reaction force Fd. Therefore, even if the magnitude of the collision load Fa and the magnitude of the bending moment are further increased, the first portion is prevented from being bent.

  Therefore, according to the vehicle door 1 </ b> B of the present embodiment, it is possible to enhance the strength against the collision load Fa applied to the outer panel 2 at the time of a side collision of the vehicle without hindering the raising and lowering of the door glass 4. Become.

Further, according to the vehicle door 1B of the present invention, when there is a possibility of a side collision by the radar sensor 9, the window sensor 10, the ECU 11B, and the window electric motor 12, the reinforcing member 16 is placed at a predetermined position in the vehicle height direction. Can be arranged. Therefore, according to the vehicle door 1B of the present embodiment, the strength against the collision load Fa applied to the outer panel 2 in the case of a side collision of the vehicle can be enhanced without depending on the lifted state of the door glass 4. It becomes possible.
(Fourth embodiment)

  Next, the configuration of the vehicle door according to the fourth embodiment of the present invention will be described with reference to FIGS. FIG. 15: is the figure which looked at the vehicle door which concerns on the 4th Embodiment of this invention from the inner surface side. In FIG. 15, in order to make the characteristic part of this embodiment easy to see, illustration of the inner panel is omitted, and a circuit block diagram of the electric system section is shown. 16 is an end view of the vehicle door taken along line XVI-XVI in FIG. 15. FIGS. 17 and 18 are end views of the vehicle door taken along line XVII-XVII in FIG. FIG. 17 shows the vehicle door 1 </ b> C with the window closed, and FIG. 18 shows the vehicle door 1 </ b> C in a state ready for a side collision.

  A vehicle door 1 </ b> C shown in FIGS. 15 to 18 includes a reinforcing member 16 </ b> A instead of the reinforcing member 16, and the reinforcing member 16 </ b> A is coupled to the door glass support member 14 without the spacer 13. This is different from the vehicle door 1B of the third embodiment. Further, the vehicle door 1C further includes a seat positioning sensor 17, and is different from the vehicle door 1B in a configuration including the ECU 11C instead of the ECU 11B. Since the other configuration of the vehicle door 1C is the same as that of the vehicle door 1B, description thereof is omitted here.

  The reinforcing member 16 </ b> A has a second portion 16 f instead of the second portion 16 b in the reinforcing member 16. The second portion 16f extends in the vehicle width direction from the entire inner surface side of the first portion 16a except for the arrangement area of the door frame 3, the window electric motor 12, the window regulator 15, and the like. The first portion 16a of the reinforcing member 16A is the same as the first portion 16a of the reinforcing member 16.

  An upper surface 16g of the reinforcing member 16A in the vehicle height direction is coupled to the door glass support member 14 without the spacer 13 interposed therebetween. That is, the reinforcing member 16 </ b> A is coupled adjacent to the door glass 4 and can be moved up and down as the door glass 4 moves up and down. Accordingly, as shown in FIG. 18, the reinforcing member 16A is arranged at a predetermined position in the vehicle height direction in a state where the window is opened by a predetermined amount. Specifically, the reinforcing member 16A is located at the seating position of the occupant in a state where the window is opened by a predetermined amount. The seating position of the passenger is, for example, the hip point position of the passenger.

  The seat positioning sensor 17 detects the seating position of the occupant, that is, the hip point position of the occupant, which varies according to the mounted weight of the vehicle, for example, by detecting the stroke amount of the suspension. The seat positioning sensor 17 outputs a stroke amount signal having a magnitude corresponding to the stroke amount of the suspension to the ECU 11C.

  The ECU 11C includes a second determination unit 11h and a drive unit 11i instead of the second determination unit 11f and the drive unit 11g, and further includes an adjustment unit 11j. The ECU 11C includes the ECU 11B of the third embodiment. Is different. Since the first determination unit 11a of the ECU 11C is the same as the ECU 11, the description thereof is omitted here.

  The adjustment part 11j has memorize | stored beforehand the predetermined raising / lowering amount of the door glass 4 when 16 A of reinforcement members are arrange | positioned in a hip point position. When the adjustment unit 11j receives the determination result information from the first determination unit 11a, based on the stroke amount signal received from the seat positioning sensor 17, the adjustment unit 11j calculates a predetermined lift amount stored in advance according to the stroke amount signal. Adjust minutes. When the adjustment of the lift amount is completed, the adjustment unit 11j outputs the adjustment end information and the adjusted lift amount to the second determination unit 11h.

  When the second determination unit 11h receives the adjustment end information from the adjustment unit 11j, the second determination unit 11h determines whether or not the reinforcing member 16A is disposed at a predetermined position based on the lift amount signal received from the window sensor 10. Specifically, the second determination unit 11h compares the lifting / lowering amount of the door glass 4 according to the lifting / lowering amount signal with the lifting / lowering amount adjusted by the adjusting unit 11j, so that the reinforcing member 16A is in a predetermined position. It is determined whether or not it is arranged. When the reinforcing member 16A is not disposed at a predetermined position, the second determination unit 11h outputs the determination result information, the lift amount signal, and the adjusted lift amount to the drive unit 11i.

  Upon receiving the determination result information from the second determination unit 11h, the drive unit 11i instructs the window electric motor 12 so that the reinforcing member 16A is disposed at a predetermined position. Specifically, the drive unit 11i obtains a difference between the lift amount corresponding to the lift amount signal and the adjusted lift amount, and electrically drives the window so as to raise and lower the door glass 4 according to the polarity and value of the difference. Command the motor 12. That is, the drive part 11i functions as a drive means of the present invention.

  Next, the operation of the vehicle door 1C according to the fourth embodiment will be described. Since the operations of the radar sensor 9 and the window sensor 10 are as described above, description thereof is omitted here.

  FIG. 19 is a flowchart showing the operation of the ECU 11C. First, the first determination unit 11a determines the possibility of a side collision by an object based on the distance signal and the speed signal received from the radar sensor 9 (step S1).

  Next, when it is determined in step S <b> 1 that there is a possibility of a side collision, the adjustment unit 11 j uses a stroke amount signal received from the seat positioning sensor 17 to store a predetermined lift amount stored in advance as a stroke amount. The stroke amount is corrected according to the signal (step S6).

  Next, the second determination unit 11 h determines whether or not the reinforcing member 16 </ b> A is disposed at a predetermined position based on the lift amount signal received from the window sensor 10. Specifically, the second determination unit 11h compares the lifting / lowering amount of the door glass 4 according to the lifting / lowering amount signal with the lifting / lowering amount adjusted by the adjusting unit 11j, so that the reinforcing member 16A is in a predetermined position. It is determined whether or not it is arranged. (Step S4).

  Next, when it is determined in step S4 that the reinforcing member 16A is not disposed at a predetermined position, the drive unit 11i drives the window electric motor 12 to raise and lower the door glass 4 and the reinforcing member 16A. In this way, the reinforcing member 16A is arranged at a predetermined position, that is, at the hip point position of the occupant (step S5).

  When it is determined in step S1 that there is no possibility of a side collision, the first determination unit 11a does not output the determination result information to the adjustment unit 11j, and as a result, the ECU 11C performs steps S6, S4, and S5. The process shown in FIG. 19 is terminated without executing the process. When it is determined in step S4 that the reinforcing member 16A is disposed at a predetermined position, the second determination unit 11h does not output the determination result information to the drive unit 11i, and as a result, the ECU 11C The process shown in FIG. 19 is terminated without executing the process of S5.

  Thus, also in the vehicle door 1C of the present embodiment, when the reinforcing member 16A is coupled to the door glass 4 and there is a possibility of a side collision, the radar sensor 9, the window sensor 10, the seat positioning sensor 17, and the ECU 11C. Since the reinforcing member 16A is moved up and down by the window electric motor 12 so as to be arranged at a predetermined position, the same advantages as the vehicle door 1B of the third embodiment can be obtained.

  Further, according to the vehicle door 1C of the present embodiment, the second portion 16f of the reinforcing member 16A extends in the vehicle width direction from the entire inner surface side of the first portion 16a. Further, the strength against the collision load Fa applied to the outer panel 2 can be further strengthened.

  Further, according to the vehicle door 1C of the present embodiment, the seat positioning sensor 17 and the adjusting unit 11j of the ECU 11C adjust the seating position of the occupant that varies depending on the mounted weight of the vehicle, that is, the hip point position of the occupant. Since the reinforcing member 16A can be appropriately disposed, the safety of the occupant during a side collision of the vehicle is improved.

  The present invention is not limited to the above-described embodiment, and various modifications can be made.

  In the first and second embodiments, the vehicle doors 1 and 1A are illustrated in which the support member 7 and the load receiving member 8 are provided one by one in the center of the side impact beam 6 in the front-rear direction of the vehicle. A plurality of members 7 and load receiving members 8 may be provided in the vehicle front-rear direction of the side impact beam 6, respectively.

  Moreover, in 3rd Embodiment, although the 2nd part 16b of the reinforcement member 16 illustrated one vehicle door 1B provided in the center part in the vehicle front-back direction of the 1st part 16a, A plurality of portions 16b may be provided in the vehicle front-rear direction of the first portion 16a.

  In the present embodiment, the vehicle doors 1, 1 </ b> A, 1 </ b> B, and 1 </ b> C provided with the radar sensor 9 are illustrated, but a CCD camera may be provided instead of the radar sensor 9. In this case, the first determination unit 11a in the ECUs 11, 11A, 11B, and 11C may determine the possibility of a side collision from the image data of the CCD camera.

  In the fourth embodiment, the predetermined lifting amount of the glass 4 is adjusted based on the stroke amount signal received from the sheet positioning sensor 17 by the adjusting unit 11j so that the reinforcing member 16A is appropriately disposed at the hip point position. However, the adjusting portion 11j adjusts the predetermined lifting amount of the glass 4 so that the reinforcing member 16A is appropriately disposed at the height of the strength member (for example, bumper, front side member, front cross member) of the other vehicle. May be. At this time, the adjusting unit 11j may adjust the predetermined lift of the glass 4 based on the vehicle height of the other vehicle (for example, the image data of the CCD camera described above) detected by the means for detecting the other vehicle. And the predetermined raising / lowering amount of the glass 4 may be adjusted based on the information (for example, bumper position received by inter-vehicle communication etc.) of the other vehicle received by the communication means.
