Mode for Carrying Out the Invention

[0009] Hereinafter, with reference to the drawings, the mounting structure of the window regulator unit according to the embodiment will be described. In each figure, FR and RR indicate the front and rear in the front-rear direction of the vehicle door, respectively, IS and OS indicate the inner and outer in the vehicle interior-exterior direction, and UP and DN indicate the upper and lower in the up-down direction of the vehicle door, respectively. Further, the front in the front-rear direction of the vehicle door means the direction in which a rotation axis (hinge) for rotatably supporting the vehicle door with respect to the vehicle body is provided in the vehicle door. Further, the rear in the front-rear direction of the vehicle door means the direction opposite to the direction in which the hinge is provided in the vehicle door. In the following description, the front and rear in the front-rear direction of the vehicle door, the upper and lower in the up-down direction of the vehicle door, and the inner and outer in the vehicle interior-exterior direction are simply referred to as "front", "rear", "upper", "lower", "vehicle interior side", and "vehicle exterior side", respectively. Also, elements having the same function are denoted by the same reference numerals, and redundant descriptions are omitted.

[0010] The mounting structure of the window regulator unit according to the embodiment can be used for mounting the window regulator unit in a vehicle door of a passenger car or a light truck (SUV, pickup truck, etc.).

[0011] As shown in FIGS. 1 to 3, the mounting structure of the window regulator unit according to the present embodiment includes a door inner panel 10, a guide member 50, and a support member 60.

[0012] The vehicle door 1 is a door that separates the interior and exterior of a vehicle (not shown), and is attached to the vehicle entrance so as to be openable and closable. In the present embodiment, the vehicle door 1 is rotatably supported (rear-opening possible) in the interior-exterior direction of the vehicle via a hinge (not shown) on the front side of the vehicle at the vehicle entrance. However, for example, the vehicle door 1 may be rotatably supported (front-opening possible) via a hinge on the rear side of the vehicle at the vehicle entrance.

[0013] As shown in FIG. 2, the vehicle door 1 includes a door inner panel 10 and a door outer panel 20. The door inner panel 10 is a plate-like member having a substantially rectangular shape when viewed in the interior-exterior direction of the vehicle, which constitutes the wall surface on the interior side of the vehicle door 1. Further, an inner opening 10a is formed on the upper side of the door inner panel 10. Note that the door inner panel 10 may include a reinforcing panel 10b that extends in the front-rear direction on the outer side of the vehicle and reinforces the door inner panel 10. The door outer panel 20 is a plate-like member having substantially the same shape as the door inner panel 10 when viewed in the interior-exterior direction of the vehicle, which constitutes the wall surface on the outer side of the vehicle door 1, and has an arcuate cross-sectional shape that bulges outward in the vehicle exterior when viewed in the front-rear direction. Further, an outer opening 20a is formed on the upper side of the door outer panel 20. The edge of the inner opening 10a and the edge of the outer opening 20a substantially overlap when viewed in the interior-exterior direction of the vehicle.

[0014] By overlapping the door inner panel 10 and the door outer panel 20 in the interior-exterior direction of the vehicle, the exterior portion of the vehicle door is formed, and the window portion of the vehicle door 1 is constituted by the inner opening 10a and the outer opening 20a. Further, a space S is formed between the door inner panel 10 and the door outer panel 20. The window portion is opened and closed by the wind panel 30 moving up and down between this space S and the window portion. For example, when the wind panel 30 is raised to the uppermost position, the window portion is in a state of being blocked by the wind panel 30 (closed state), and when the wind panel 30 is lowered, the window portion is in a state of not being blocked by the wind panel 30 (open state).

[0015] As shown in FIGS. 1 to 2, the window panel 30 is supported so as to be movable up and down by a window regulator unit 40 disposed in the space S. Further, as shown in FIG. 3, the window regulator unit 40 includes a guide member 50, a support member 60, a lifting member 41, a drive unit 42, and a wire 43, and is disposed outside the vehicle compartment of the door inner panel 10. Note that the central portion of the door inner panel 10 bulges and is formed toward the vehicle compartment side so as to be able to accommodate the drive unit 42. Therefore, an increase in the thickness in the vehicle compartment interior and exterior direction of a region of the vehicle door 1 that does not overlap with the drive unit 42 when viewed in the vehicle compartment interior and exterior direction can be suppressed.

[0016] The guide member 50 is a long member having a cross-sectional hat shape that extends in the vertical direction outside the vehicle compartment of the door inner panel and opens outside the vehicle compartment in a plan view. Further, as shown in FIG. 2, the guide member 50 has a shape that bulges outward from the vehicle compartment in a front-rear direction view of the vehicle door. A support member 60 is provided between the upper end portion 50U and the lower end portion 50D of the guide member 50, and the guide member 50 is supported by the door inner panel 10 when the support member 60 abuts against and is fixed to the door inner panel 10.

[0017] Further, as shown in FIG. 8, the surface (contact surface 60a) of the support member 60 that contacts the door inner panel 10 is formed so as to be raised while bending its peripheral edge portion outward from the vehicle compartment. In other words, the peripheral edge portion of the surface (contact surface 60a) of the support member 60 that contacts the door inner panel 10 is bent outward from the vehicle compartment. Therefore, a curved surface R that bends outward from the contact surface 60a is formed at the peripheral edge portion of the contact surface 60a.

[0018] Note that the upper end portion 50U of the guide member 50 refers to the region including the upper end edge of the guide member 50 and its vicinity. Specifically, it refers to the region extending downward from the upper end edge of the guide member 50 at a predetermined ratio with respect to the vertical dimension of the guide member 50. Note that the predetermined ratio can be appropriately set according to the dimension in the longitudinal direction or the short-side direction of the guide member 50, the installation position with respect to the door inner panel 10, or the installation structure, etc. For example, in a certain embodiment, the predetermined ratio with respect to the vertical dimension of the guide member 50 may be one-fifth. Also, in the present embodiment, the portion of the guide member 50 located above the upper support member 60U described later is the upper end portion 50U.

[0019] Also, the lower end portion 50D of the guide member 50 refers to the region including the lower end edge of the guide member 50 and its vicinity. Specifically, it refers to the region extending upward from the lower end edge of the guide member 50 at a predetermined ratio with respect to the vertical dimension of the guide member 50. Note that the predetermined ratio can be appropriately set according to the dimension in the longitudinal direction or the short-side direction of the guide member 50, the installation position with respect to the door inner panel 10, or the installation method, etc. For example, in a certain embodiment, the predetermined ratio with respect to the vertical dimension of the guide member 50 may be one-fifth. Also, in the present embodiment, the portion of the guide member 50 located below the lower support member 60D described later is the lower end portion 50D.

[0020] Note that the illustrated support member 60 includes the upper support member 60U located at the uppermost position and the lower support member 60D located at the lowermost position. However, the number of support members 60 may be one or two or more. In other words, at least one support member 60 for supporting the guide member 50 may be provided between the upper end portion 50U and the lower end portion 50D of the guide member 50.

[0021] The elevating member 41 is a block-shaped member that is supported so as to be elevable on the vehicle exterior side of the guide member 50. As shown in FIGS. 1 to 2, the lower end portion of the window panel 30 is supported on the vehicle exterior side of the elevating member 41 via a fixture such as a bracket. In other words, the window panel 30 is supported by the guide member 50 so as to be elevable. For this reason, when the elevating member 41 moves up and down along the guide member 50, the window panel 30 moves up and down between the window portion of the vehicle door 1 and the space S, opening and closing the window portion.

[0022] The drive unit 42 is fixed via a fixture such as a bracket to the vehicle interior side of the substantially central portion in the vertical direction of the guide member 50. Further, the vehicle interior side of the drive unit 42 is fixed to the door inner panel 10 via a fixture such as a bracket. The drive unit 42 includes a motor 42a and a winding portion 42b.

[0023] The winding portion 42b includes a cylindrical winding drum (not shown) having a winding shaft extending in the vehicle interior-exterior direction inside the drive unit 42 as a central axis. The shaft rotation of the motor 42a is configured to be transmitted to the winding drum via a worm gear (not shown) and a speed reducer (not shown) attached to the shaft. Therefore, by controlling the rotation direction of the motor 42a, the rotation around the winding shaft of the winding drum can be controlled.

[0024] The wire 43 is composed of an ascending wire 43a and a descending wire 43b. One end portion of the ascending wire 43a is fixed to the elevating member 41. The ascending wire 43a extends upward from the elevating member 41, extends obliquely downward along a guide pulley 51 pivotally supported at the upper end of the guide member 50, is wound around the winding drum a predetermined number of times, and then the other end portion is fixed to the winding drum. Further, one end portion of the descending wire 43b is fixed to the elevating member 41. The descending wire 43b extends downward from the elevating member 41, extends obliquely upward along a guide pulley 51 pivotally supported at the lower end of the guide member 50, is wound around the winding drum a predetermined number of times, and then the other end portion is fixed to the winding drum.

[0025] Therefore, by controlling the rotation of the motor 42a, the forward rotation (clockwise rotation in FIG. 3) or reverse rotation (counterclockwise rotation in FIG. 3) of the take-up drum can be controlled, the winding or feeding of the wire 43a for raising or the wire 43b for lowering can be controlled, and the raising and lowering of the lifting member 41 can be controlled. For example, by transmitting the driving force of the motor 42a to the take-up drum and causing the take-up drum to rotate forward, the wire 43a for raising can be wound by the take-up drum and the wire 43b for lowering can be fed out from the take-up drum, and the lifting member 41 can be raised. Since the lifting member 41 supports the lower end portion of the window panel 30, the window panel 30 can also be raised, and the window portion of the vehicle door 1 can be closed. In this way, the window regulator unit 40 can control the raising and lowering of the window panel 30 and switch between the open state and the closed state of the window portion of the vehicle door 1.

[0026] Next, the configuration of the guide member 50 will be described more specifically.

[0027] As shown in FIGS. 1 to 5, an upper elastic member 70 is interposed between the upper end portion 50U of the guide member 50 and a region (upper facing portion 11) of the door inner panel 10 that faces the upper end portion 50U of the guide member 50 in the vehicle interior-exterior direction. In the illustrated example, the upper elastic member 70 is fixed to the upper end portion 50U of the guide member 50, but the upper elastic member 70 may be fixed to the upper facing portion 11 of the door inner panel 10.

[0028] Also, as shown in FIG. 5, the upper elastic member 70 is arranged with a gap between the upper facing portion 11 of the reinforcing panel 10b (door inner panel 10) in the vehicle interior-exterior direction. The size of the gap is not particularly limited, but for example, it is 0.1 mm to 1 mm. When the upper elastic member 70 is provided on the upper facing portion 11, the upper elastic member 70 may be arranged with a gap between the upper end portion 50U in the vehicle interior-exterior direction. In other words, the upper elastic member 70 may be arranged in a state of being separated from either the upper facing portion 11 of the door inner panel 10 or the upper end portion 50U of the guide member 50 in the vehicle interior-exterior direction. However, in the vehicle interior-exterior direction, the upper end portion 50U and the upper elastic member 70 may be in contact, and the upper elastic member 70 and the upper facing portion 11 may be in contact. Further, the upper elastic member 70 may be arranged in a state (compressed state) where it is deformed and distorted by being compressed between the upper end portion 50U and the upper facing portion 11.

[0029] The upper elastic member 70 shown in FIG. 4 is entirely composed of a rubber material. However, the upper elastic member 70 only needs to include an upper rubber member 70a made of a rubber material provided on the vehicle interior side at the upper end portion 50U of the guide member 50. In the illustrated example, the upper rubber member 70a is directly fixed to the guide member 50. More specifically, the upper rubber member 70a as the upper elastic member 70 is directly fixed to the guide member 50 by sandwiching the upper edge of the guide member 50 with a groove provided below the upper rubber member 70a. However, for example, the upper rubber member 70a may be directly fixed to the vehicle interior side of the upper end portion 50U of the guide member 50 using an adhesive or the like, or may be directly fixed using other methods. Thereby, the number of parts of the window regulator unit 40 according to the present embodiment can be reduced, and the attachment structure of the window regulator unit 40 according to the embodiment can be easily configured.

[0030] Note that, as shown in FIGS. 1 to 3, a lower elastic member 80 may be interposed between a lower end portion 50D of a guide member 50 and a region (lower opposing portion 12) of a door inner panel 10 that opposes the lower end portion 50D in the vehicle interior-exterior direction. Also, in the illustrated example, the lower elastic member 80 is fixed to the vehicle interior side of the lower end portion 50D of the guide member 50, but the lower elastic member 80 may be fixed to the vehicle exterior side of the lower opposing portion 12 of the door inner panel 10.

[0031] The vehicle exterior side of the illustrated lower elastic member 80 is fixed to the lower end portion 50D of the guide member 50, and the vehicle interior side is arranged in a state of being pressed against the lower opposing portion 12 of the door inner panel 10. Therefore, the lower elastic member 80 is arranged in a compressed state by being pressed in the vehicle interior-exterior direction against the lower end portion 50D and the lower opposing portion 12. In other words, the lower elastic member 80 is arranged in a state of contacting both the lower opposing portion 12 of the door inner panel 10 and the lower end portion 50D of the guide member 50 in the vehicle interior-exterior direction and in a compressed state. However, the arrangement method is not limited to this, and the lower elastic member 80 fixed to the lower end portion 50D of the guide member 50 and the door inner panel 10 may be in a separated state. Further, when the lower elastic member 80 is fixed to the vehicle exterior side of the lower opposing portion 12 of the door inner panel 10, the lower elastic member 80 and the guide member 50 may be in a separated state.

[0032] Also, as shown in FIGS. 6 to 7, the lower elastic member 80 includes a leaf spring member 80b extending in the vehicle interior direction from the lower end portion 50D of the guide member 50, and a lower rubber member 80a provided on the vehicle interior side of the leaf spring member 80b.

[0033] The leaf spring member 80b is a bent plate-shaped member having a substantially Z-shaped cross-sectional shape when viewed in the front-rear direction. Also, the front-rear dimension of the leaf spring member 80b and the front-rear dimension of the lower end portion 50D of the guide member 50 are substantially the same. The upper side of the leaf spring member 80b is fixed to the vehicle interior side of the lower end portion 50D of the guide member 50. Also, the lower side of the leaf spring member 80b extends so as to stand up from the guide member 50 toward the vehicle interior, and further, the tip portion is bent downward. By doing so, the leaf spring member 80b having elasticity in the vehicle interior-exterior direction is fixed to the lower end portion 50D of the guide member 50.

[0034] The lower rubber member 80a is a member made of a rubber material having a substantially rectangular cross-sectional shape when viewed in the vehicle interior-exterior direction. Also, the front-rear dimension of the lower rubber member 80a is configured to be slightly larger than the front-rear dimension of the leaf spring member 80b. The vehicle exterior side of the lower rubber member 80a is fixed to the leaf spring member 80b. Also, the vehicle interior side of the lower rubber member 80a has a lower rubber member surface as a surface facing the lower opposing portion 12 of the door inner panel 10, and a recess 80c is formed in the surface. The recess 80c is a groove extending in the vertical direction on the lower rubber member surface and has a substantially rectangular shape when viewed in the vertical direction. By forming the recess 80c, the lower rubber member surface becomes an uneven surface. In an embodiment, the vehicle interior-exterior dimension of the lower rubber member 80a is about 10 mm, and the vehicle interior-exterior dimension of the recess 80c is about 2 mm. However, these dimensions are not limited thereto.

[0035] Also, the lower elastic member 80 is arranged in a state where the rear side thereof is pressed more strongly against the door inner panel 10 than the front side thereof. Therefore, the distal portion 80d of the lower elastic member 80 is arranged in a compressed state compared to the proximal portion 80e. More specifically, for example, when viewed in the vertical direction, a gradient with respect to the front-rear direction may be provided on the lower rubber member surface so that the distal portion 80d is located more toward the vehicle interior than the proximal portion 80e. The distal portion 80d is a region of the lower elastic member 80 that is far from the rotation axis (hinge) of the vehicle door 1, and the proximal portion 80e is a region of the lower elastic member 80 that is closer to the rotation axis (hinge) than the distal portion 80d.

[0036] Note that the elastic coefficient of the lower elastic member 80 may be set lower than that of the upper elastic member 70. For example, in a certain embodiment, a rubber member with a Shore hardness (Hs) of 60 may be used as the lower rubber member 80a, and a rubber member with Hs of 70 may be used as the upper rubber member 70a.

[0037] Next, with reference to FIGS. 9 to 10, the operation of the mounting structure of the window regulator unit 40 according to the embodiment when the vehicle door 1 is closed will be described.

[0038] When a passenger gets into or out of the vehicle, an operation is performed to change the vehicle door 1 from an open state to a closed state. Since the front of the vehicle door 1 is attached to the vehicle via a hinge, in this operation, first, the vehicle door 1 rotates about the hinge toward the vehicle entrance and approaches the vehicle entrance with a speed facing the interior of the vehicle compartment. Then, when the peripheral edge of the vehicle door 1 abuts against the peripheral edge of the vehicle entrance, an external force directed outward of the vehicle compartment is input to the vehicle door 1. As a result, an acceleration directed outward of the vehicle compartment is generated in the vehicle door 1, and the speed is rapidly reduced to become stationary with respect to the vehicle. In other words, the vehicle door 1 that has abutted against the vehicle entrance with a speed facing the interior of the vehicle compartment becomes stationary with respect to the vehicle due to the acceleration generated when the vehicle door 1 is closed. Note that the acceleration when the vehicle door 1 is closed refers to the acceleration directed outward of the vehicle compartment that results from an external force directed outward of the vehicle compartment being input to the vehicle door 1 when the peripheral edge of the vehicle door 1 abuts against the peripheral edge of the vehicle entrance during the operation of closing the vehicle door 1.

[0039] When an acceleration occurs when the vehicle door 1 is closed, an inertial force directed toward the interior of the vehicle compartment is generated in the window regulator unit 40. As a result of the generation of the inertial force, as shown in FIG. 9, a load in the direction of arrow B is input from the support member 60 to the door inner panel 10. Thereby, the door inner panel 10 is elastically deformed, and the upper end portion 50U of the guide member 50 and the upper opposing portion 11 of the door inner panel 10 relatively approach each other. Also, the lower end portion 50D of the guide member 50 and the lower opposing portion 12 of the door inner panel 10 relatively approach each other. Note that, as a mode of elastic deformation of the door inner panel 10, for example, a mode in which the upper opposing portion 11 and the lower opposing portion 12 of the door inner panel 10 rotate in the direction of arrow C with the support member 60 as a fulcrum, or a mode in which the support member 60 is pushed into the door inner panel 10 so that the guide member 50 and the door inner panel 10 approach each other as a whole, etc.

[0040] (1) The mounting structure according to the embodiment is a mounting structure of the window regulator unit 40, and includes a door inner panel 10 that constitutes the interior side of the vehicle compartment of the vehicle door 1, and a guide member 50 that extends in the vertical direction outside the vehicle compartment of the door inner panel 10 and supports the window panel 30 so as to be movable up and down. Between the upper end portion 50U and the lower end portion 50D of the guide member 50, at least one support member 60 that is fixed to the door inner panel 10 and supports the guide member 50 is provided. An upper elastic member 70 is interposed between the upper end portion 50U of the guide member 50 and the upper opposing portion 11 of the door inner panel 10 that opposes the upper end portion 50U in the vehicle compartment interior and exterior direction. It is configured such that the upper end portion 50U and the upper opposing portion 11 approach each other and compress the upper elastic member 70 due to elastic deformation caused at least by the acceleration when the vehicle door 1 is closed.

[0041] Therefore, as the upper end portion 50U of the guide member 50 and the upper opposing portion 11 of the door inner panel 10 approach each other relatively, the upper elastic member 70 comes into contact with the upper opposing portion 11, and a compressive force is input to the upper elastic member 70 between the upper end portion 50U and the upper opposing portion 11. Then, the reaction force (restoring force) of the upper elastic member 70 in the compressed state is input to the upper end portion 50U and the upper opposing portion 11. At this time, a part of the load caused by the inertial force in the vehicle interior direction of the window regulator unit 40 due to the acceleration when the vehicle door 1 is closed is input to the door inner panel 10 through the upper elastic member 70. Therefore, the load is dispersed to the support member 60 and the upper elastic member 70 and input to the door inner panel 10. Accordingly, it is possible to reduce the load input from the support member 60 of the window regulator unit 40 toward the door inner panel 10 when the vehicle door 1 is closed. Further, when closing the vehicle door 1, the window portion of the vehicle door 1 is often in a closed state. In such a case, since the window panel 30 is supported above the guide member 50, the center of gravity of the window regulator unit 40 exists at a high position in the vertical direction. Therefore, when the acceleration occurs when the vehicle door 1 is closed, a large inertial force is generated on the upper side of the guide member 50. For this reason, by providing the upper elastic member 70 at the upper end portion 50U, while reducing the number of components of the window regulator unit 40 according to the embodiment, the load caused by the inertial force of the window regulator unit 40 can be effectively dispersed to the support member 60 and the upper elastic member 70, and the load input from the support member 60 toward the door inner panel 10 can be reduced.

[0042] (2) In the mounting structure according to the embodiment, the upper elastic member 70 includes an upper rubber member 70a provided on the vehicle interior side at the upper end portion 50U of the guide member 50.

[0043] Therefore, among the loads caused by the inertial force of the window regulator unit that occur when the vehicle door 1 is closed, the load distributed to the upper elastic member 70 is absorbed by the upper rubber member 70a, and the generation of lower-level noise due to the contact between the upper opposing portion 11 and the upper elastic member 70 can be suppressed.

[0044] (3) In the mounting structure according to the embodiment, the upper rubber member 70a is directly fixed to the guide member 50.

[0045] Therefore, the number of components required to configure the mounting structure of the window regulator unit 40 according to the embodiment can be reduced, and the mounting structure can be configured simply.

[0046] (4) In the mounting structure according to the embodiment, a lower elastic member 80 is interposed between the lower end portion 50D of the guide member 50 and the lower opposing portion 12 of the door inner panel 10 that faces the lower end portion 50D in the vehicle interior and exterior direction. The lower end portion 50D and the lower opposing portion 12 are configured to approach each other and compress the lower elastic member 80 due to elastic deformation caused by at least the acceleration when the vehicle door 1 is closed.

[0047] Therefore, as the lower end portion 50D of the guide member 50 and the lower opposing portion 12 of the door inner panel 10 approach each other relatively, a compressive force is input to the lower elastic member 80 between the lower end portion 50D and the lower opposing portion 12. Then, the reaction force (restoring force) of the lower elastic member 80 in the compressed state is input to the lower end portion 50D and the lower opposing portion 12. At this time, a part of the load caused by the inertial force directed toward the vehicle interior of the window regulator unit 40 due to the acceleration when the vehicle door 1 is closed is input to the door inner panel 10 through the lower elastic member 80. Therefore, the load is dispersed to the support member 60, the upper elastic member 70, and the lower elastic member 80 and input to the door inner panel 10. Accordingly, the load input from the support member 60 of the window regulator unit 40 toward the door inner panel 10 when the vehicle door 1 is closed can be more reliably reduced. Further, when the window portion is in the open state when the vehicle door 1 is closed, since the window panel 30 is supported below the guide member 50, the center of gravity of the window regulator unit 40 exists at a low position in the vertical direction. Therefore, when the acceleration occurs when the vehicle door 1 is closed, a larger inertial force is generated by the lower side of the guide member 50. Therefore, when the vehicle door is closed, there is a possibility that more load is input by the lower support member 60D. Also, due to design considerations, it may be difficult to increase the rigidity of the portion of the door inner panel 10 where the lower support member 60D is fixed and the surrounding area. Even in such a case, since the load is dispersed to the lower elastic member 80, the load input from the lower support member 60D toward the door inner panel 10 can be more reliably reduced.

[0048] (5) In the mounting structure according to the embodiment, the elastic coefficient of the lower elastic member 80 is lower than the elastic coefficient of the upper elastic member 70.

[0049] Therefore, the reaction force exerted by the compressed lower elastic member 80 on the lower end portion 50D and the door inner panel 10 is smaller than the reaction force exerted by the compressed upper elastic member 70 on the upper end portion 50U and the door inner panel 10. As a result, it is possible to prevent the sum of the reaction force of the upper elastic member 70 and the reaction force of the lower elastic member 80 from becoming excessively large, and to more reliably distribute the load caused by the inertial force of the window regulator unit 40 when the vehicle door 1 is closed to the support member 60, the upper elastic member 70, and the lower elastic member 80. In other words, the elastic coefficient of the upper elastic member 70 is higher than the elastic coefficient of the lower elastic member 80. Therefore, even when the window panel 30 is in the raised state and the center of gravity of the window regulator unit is at a high position in the vertical direction, it is possible to prevent the load caused by the inertial force of the window regulator unit 40 when the vehicle door 1 is closed from being excessively input to the upper support member 60U due to excessive compression of the upper elastic member 70.

[0050] (6) In the mounting structure according to the embodiment, the upper elastic member 70 is disposed in a state of being separated from either the upper opposing portion 11 of the door inner panel 10 or the upper end portion 50U of the guide member 50 in the vehicle interior-exterior direction, and the lower elastic member 80 is disposed in a state of being in contact with both the lower opposing portion 12 of the door inner panel 10 and the lower end portion 50D of the guide member 50 and being compressed.

[0051] Regarding the operation of such a configuration, for example, the upper elastic member 70 fixed to the vehicle interior side of the upper end portion 50U is disposed in a state of having a gap with the upper opposing portion 11 in the vehicle interior-exterior direction, and the lower elastic member 80 fixed to the vehicle interior side of the lower end portion 50D is pressed against the lower opposing portion 12 and disposed in a compressed state. An example of the mounting structure will be described with reference to FIG. 10.

[0052] The horizontal axis X in FIG. 10 represents the relative movement amount (pushing-in amount) of the window regulator unit 40 with respect to the door inner panel 10 when the vehicle door 1 is closed. The vertical axis Y represents the value of the sum (total reaction force) of the magnitude of the reaction force input by the lower elastic member 80 to the lower end portion 50D and the lower opposing portion 12 and the magnitude of the reaction force input by the upper elastic member 70 to the upper end portion 50U and the upper opposing portion 11 at a certain pushing-in amount. The solid line L represents the change in the total reaction force with respect to the change in the pushing-in amount. The origin O is a state where no relative movement of the window regulator unit 40 with respect to the door inner panel 10 occurs. XC represents the pushing-in amount when the upper end portion 50U and the upper opposing portion 11 approach relatively and the upper elastic member 70 comes into contact with the upper opposing portion 11 due to the closing of the vehicle door 1.

[0053] First, at the origin O, since the upper elastic member 70 is not in a compressed state, it does not have a reaction force. On the other hand, since the lower elastic member 80 is arranged in a compressed state, it has a predetermined reaction force magnitude Y0. When the pushing-in amount increases due to closing the vehicle door 1, the lower elastic member 80 becomes more strongly compressed, and as shown by the change of the solid line L from the origin O to XC, the magnitude of the reaction force of the lower elastic member 80 increases to YC. In this state, the load caused by the inertial force of the window regulator unit 40 when the vehicle door 1 is closed is dispersed to the support member 60 and the lower elastic member 80. Further, after the upper elastic member 70 and the upper opposing portion 11 come into contact at the pushing-in amount XC, when the pushing-in amount becomes larger than XC, the upper elastic member 70 is in a compressed state between the upper end portion 50U and the upper opposing portion 11. At this time, since the upper elastic member 70 and the lower elastic member 80 have reaction forces, the total reaction force increases more greatly compared to the case where the pushing-in amount is below XC. In this state, the load is dispersed to the support member 60, the upper elastic member 70, and the lower elastic member 80. According to the above actions, regardless of the position of the window panel 30 in the vertical direction, the load caused by the inertial force of the window regulator unit 40 generated when the vehicle door 1 is closed is first dispersed to the support member 60 and the lower elastic member 80. Next, as the upper end portion 50U and the upper opposing portion 11 relatively approach each other, the upper elastic member 70 and the upper opposing portion 11 come into contact, and the load is further dispersed to the upper elastic member 70. Therefore, regardless of the position of the window panel 30 in the vertical direction, the load can be more reliably dispersed to the support member 60, the upper elastic member 70, and the lower elastic member 80. Further, for example, when the window portion of the vehicle door 1 is in a closed state and the center of gravity of the window regulator unit 40 exists at a high position in the vertical direction, after the upper elastic member 70 and the upper opposing portion 11 come into contact, a moment may occur in which the window panel 30 rotates toward the vehicle interior and the lower end portion 50D rotates toward the vehicle exterior with the upper elastic member 70 as a fulcrum. Even in such a case, the load can be more reliably dispersed to the lower elastic member 80 before the moment occurs.

[0054] In the mounting structure according to the embodiment, the lower elastic member 80 includes a leaf spring member 80b extending from the lower end portion 50D of the guide member 50 toward the vehicle interior, and a lower rubber member 80a provided on the vehicle interior side of the leaf spring member 80b.

[0055] Therefore, among the loads caused by the inertial force of the window regulator unit 40 when the vehicle door 1 is closed, the load distributed to the lower elastic member 80 can be absorbed by the leaf spring member 80b.

[0056] In the mounting structure according to the embodiment, the lower rubber member 80a has a concave portion 80c on the surface facing the door inner panel 10 of the lower rubber member 80a.

[0057] Therefore, it is possible to suppress the lower rubber member 80a from inputting an excessive reaction force to the door inner panel 10. Furthermore, it is possible to suppress the adhesion of the lower rubber member 80a to the door inner panel 10, and to suppress the generation of sound (attachment / detachment sound) when the lower rubber member 80a adheres to or detaches from the door inner panel.

[0058] In the mounting structure according to the embodiment, the distal portion 80d of the lower elastic member 80, which is far from the rotation axis of the vehicle door 1, is arranged in a compressed state compared to the proximal portion 80e, which is closer to the rotation axis than the distal portion 80d.

[0059] Therefore, when the vehicle door 1 is closed, the load input by the distal portion 80d of the lower elastic member 80 to the door inner panel 10 is greater than the load input by the proximal portion 80e to the door inner panel 10. Thereby, when the vehicle door is closed, it is possible to suppress the window regulator unit 40 from rotating about the vertical direction toward the rear.

[0060] In the mounting structure according to the embodiment, the peripheral edge portion of the surface of at least one support member 60 that abuts against the door inner panel 10 is bent outward toward the vehicle exterior.

[0061] Therefore, the load caused by the inertial force of the window regulator unit 40 when the vehicle door 1 is closed is dispersed onto a surface such as the contact surface 60a or the curved surface R formed at its peripheral portion and input to the door inner panel 10. Accordingly, compared with the case where an edge is formed at the peripheral portion of the contact surface 60a, it is possible to suppress the concentrated input of the load.

[0062] In addition, in the above-described embodiment, a passenger car or a light truck has been taken as an example for description. However, it goes without saying that the mounting structure of the window regulator unit 40 according to the embodiment can be used for the window regulator unit of a vehicle door of a commercial vehicle such as a large truck.
