Description

Technical Field

[0001] This utility model relates to a vehicle door. Background Technology

[0002] In the prior art, there is a type of vehicle door equipped with an upper door reinforcement member that reinforces the lower edge of the window opening and a handle reinforcement member that reinforces the periphery of the door handle. In this type of vehicle door, because the area at the front end of the joint where the upper door reinforcement member and the handle reinforcement member meet has a large strength difference along the length of the vehicle, this area with a large strength difference is prone to become the starting point of door bending during a side collision. Since the corner of the bent part protrudes inward into the passenger compartment, it may collide with occupants in the vehicle seats next to the door, thus posing a safety hazard to the aforementioned reinforcement structure. Utility Model Content

[0003] In view of the above situation, the purpose of this utility model is to provide a vehicle door that can limit the bending start point of the door in the event of a side collision to an area further forward than the vehicle seat.

[0004] As a technical solution to solve the above-mentioned technical problems, the present invention provides a vehicle door, which includes an outer door panel, an inner door panel, and a door window constituting the main body of the door. A door handle is provided near the rear end of the outer door panel in the vehicle length direction. On the inner side of the outer door panel, an upper door reinforcement member extending along the lower edge of the window opening of the door window and a handle reinforcement member extending downward from the upper door reinforcement member and surrounding the mounting portion of the door handle are provided. The handle reinforcement member is characterized in that: the front part of the handle reinforcement member forms an extension portion extending toward the front end side of the main body of the door in the vehicle length direction. The extension portion is configured such that its lower end extends toward the front end side of the main body of the door while tilting upward, and the front end of the extension portion extends to a position forward of the middle part of the main body of the door in the vehicle length direction.

[0005] Typically, the side of a vehicle seat is adjacent to the rear half of the door body along the vehicle's length. Therefore, occupants seated in the vehicle seat are relatively close to the rear half of the door body. To protect occupants in the vehicle seat, in the event of a side collision, it must be ensured that the rear half of the door body does not protrude inwards into the passenger compartment.

[0006] Based on the above-described structure of this utility model, since the front part of the handle reinforcing member has an extension extending towards the front end of the door body, and the lower end of this extension extends towards the front end of the door body while tilting upwards, that is, the width of the extension gradually decreases in the vehicle height direction, the strength of the extension gradually decreases towards the front side in the vehicle length direction. When the middle area of ​​the vehicle door is impacted by other vehicles (i.e., a side collision), the area near the front end of the extension becomes the starting point of door bending. Since the front end of the extension extends to a position further forward than the middle part of the door body in the vehicle length direction, when a side collision occurs, the starting point of door bending will occur at a position further forward than the middle part of the door body. That is, the starting point of door bending will not be in the rear half of the door body, but in the front half of the door body.

[0007] Thus, since the bending point of the door can be limited to the area near the front end of the extension of the handle reinforcement member, by extending the front end of the extension to a position forward of the middle part of the door body in the vehicle length direction, the bending point of the door during a side collision can be limited to an area forward of the vehicle seat. Therefore, even if the vehicle door bends and the corner of the bent portion protrudes inward into the passenger compartment during a side collision, the corner is less likely to collide with occupants in the vehicle seats near the rear half of the door body, thereby improving vehicle safety.

[0008] In addition, in the vehicle door of the present invention, it is preferred that the upper door reinforcement member and the handle reinforcement member are independent components, and the upper door reinforcement member and the handle reinforcement member are joined together.

[0009] This structure facilitates the processing of upper door reinforcement components and handle reinforcement components.

[0010] In addition, in the vehicle door of the present invention, it is preferred that the handle reinforcing member is configured as a plate, the thickness direction of which is consistent with the thickness direction of the outer panel of the door; and an opening extending through the plate along the thickness direction is formed in the inner region of the extension of the handle reinforcing member.

[0011] Based on this structure, the weight of the handle reinforcement component can be reduced, and the strength distribution of the extension can be adjusted, which helps to limit the bending point of the door to near the front end. Attached Figure Description

[0013] Figure 2 is a schematic left view of a vehicle equipped with the vehicle doors shown in Figure 1.

[0014] Figure 3 is a schematic diagram showing the state of the vehicle door when a side collision occurs, illustrating the state seen from the outside of the vehicle after the outer door panel is made transparent. Detailed Implementation

[0015] Hereinafter, the vehicle door of the present invention will be described with reference to the accompanying drawings. In the following description, "vehicle door" will be simply referred to as "door".

[0016] Figure 2 is a schematic left view of a vehicle 1 equipped with the doors 2 of this embodiment. In this embodiment, the present invention will be described using a vehicle 1 shown in Figure 2, which has a total of four doors 2 (only the left front door and the left rear door are shown in Figure 2) and a tailgate 3. Furthermore, in this embodiment, the left rear door will be used as a representative of the four doors 2 for description.

[0017] Figure 1 is a schematic diagram showing the general structure of the door 2 according to this embodiment, illustrating the state seen from the inside of the vehicle compartment after the inner panel of the door is made transparent. In Figure 1, arrow Fr indicates the front of the vehicle, and arrow Up indicates the upper side of the vehicle.

[0018] As shown in Figure 1, the car door 2 includes an outer door panel 21, an inner door panel 22 (see Figure 3 described later), and a door glass (door window) 4, which constitute the main body of the car door.

[0019] Although not shown in detail, there is a space between the outer door panel 21 and the inner door panel 22. Within this space, a door glass 4 that can move up and down is disposed, along with a lifting mechanism (not shown) for raising and lowering (moving up and down) the door glass 4. At the upper part of the door body, a window opening 23 is formed, serving as the window frame for the door glass 4. When the door glass 4 is raised, this window opening 23 is closed.

[0020] In door 2, the rear half of the door body in the vehicle length direction (the area from the single-dotted line in Figure 1 to the rear end of the door body in the vehicle length direction) is located next to the vehicle seat 5 (in this case, the rear seat). That is, in the vehicle width direction, the rear half of the door body is adjacent to the side of the vehicle seat 5.

[0021] On the outer panel 21 of the door, there is a door handle 7, an upper door reinforcement member 8, and a handle reinforcement member 9. The following is a detailed description of each member (7, 8, 9).

[0022] The door handle 7 is located near the rear end of the outer door panel 21 along the length of the vehicle. The door handle 7 is used by occupants of the vehicle 1 to hold the door 2 when opening and closing it.

[0023] The upper door reinforcement member 8 is provided on the inner side of the outer door panel 21, extending along the lower edge of the window opening 23 in the vehicle length direction. More specifically, the upper door reinforcement member 8 is made of a strip of metal sheet, and its thickness direction is aligned with the thickness direction of the outer door panel 21, and it is installed on the inner side of the outer door panel 21. By providing this upper door reinforcement member 8, the strength near the lower edge of the window opening 23 can be improved.

[0024] The handle reinforcement member 9 is a component independent of the upper door reinforcement member 8. This handle reinforcement member 9 extends downwards from the upper door reinforcement member 8, surrounds the mounting area of ​​the door handle 7, and joins with the upper door reinforcement member 8. Specifically, the upper end of the handle reinforcement member 9 joins with the lower end of the upper door reinforcement member 8. The joining method can be, for example, welding or bolting.

[0025] The handle reinforcement component 9 is made of a metal plate, and its thickness direction is consistent with the thickness direction of the outer door panel 21. It is installed on the inner side of the outer door panel 21.

[0026] More specifically, as shown in Figure 1, the handle reinforcement member 9 consists of a rectangular main body and an extension 91 extending from the front of the main body toward the front end of the door 2 in the length direction. A quadrilateral opening 92 penetrating along the thickness direction is formed in the inner region of the main body of the handle reinforcement member 9. The handle reinforcement member 9 is installed on the inner side of the outer door panel 21 such that the area within the opening 92 corresponds to the mounting position of the door handle 7, thereby reinforcing the periphery of the door handle 7 through the main body of the handle reinforcement member 9.

[0027] The extension 91 extends from the front of the main body of the handle reinforcement member 9 toward the front end of the door 2, while its width (dimension in the vehicle height direction) gradually decreases. More specifically, the extension 91 is configured as an approximately right-angled triangle in top view (side view relative to the vehicle body in Figure 1). The long side of this right-angled triangle (extension 91) extends integrally with the upper end of the main body along the vehicle length direction and joins with the lower end of the upper door reinforcement member 8; the short side of this right-angled triangle (extension 91) is integrally connected with the front of the main body; the hypotenuse of this right-angled triangle (extension 91) is located below the long side and extends from the lower end of the short side toward the front end of the door 2 while gradually sloping upward.

[0028] In addition, an opening 93 extending through the plate thickness direction is formed in the inner region of the extension 91. The top view shape of the opening 93 is consistent with the top view shape of the extension 91, and is a smaller right-angled triangle.

[0029] In this embodiment, as shown in FIG1, the front end 94 of the extension 91 extends to a position further forward than the middle part of the door body in the vehicle length direction (see the dashed line in FIG1). That is, the front end 94 of the extension 91 is located in the front half region of the door 2 (door body) (the region from the dashed line in FIG1 to the front end of the door body in the vehicle length direction). The distance between the front end 94 of the extension 91 and the middle part can be specifically set according to the relative positional relationship between the door 2 and the vehicle seat 5 in the vehicle length direction and other structures of the door body.

[0030] By providing a handle reinforcement member 9 with an extension 91, not only is the periphery of the door handle 7 reinforced, but the area from the door handle 7 to the front end 94 of the handle reinforcement member 9 is also reinforced to varying degrees. The right-angled triangular extension 91 gradually decreases in width along the vehicle height direction and has an opening 93 on its inner side. Therefore, its strength decreases closer to the front end 94. Furthermore, since the front end 94 is a corner, in the event of a side collision, the area where the front end 94 is located within the door body of the door 2 will become the starting point of the door's bending.

[0031] Figure 3 is a schematic diagram showing the state of the vehicle door when a side collision occurs, illustrating the state seen from the outside of the vehicle after the outer door panel 21 is made transparent.

[0032] When a side impact occurs where the side of the door 2 is hit by another vehicle, as shown in Figure 3, the part where the front end 94 of the extension 91 of the handle reinforcement member 9 is located (the part on the main body of the door 2 that is further forward than the middle part in the length direction) becomes the starting point of the door bending.

[0033] Since the bending point of the aforementioned door is located in the front half of the door 2, rather than the rear half, it is far from the vehicle seat 5. Even if a side collision of the vehicle 1 causes the door 2 to bend, and the bend corner 10 protrudes into the passenger compartment, the bend corner 10 is unlikely to collide with the occupant 6 in the vehicle seat 5.

[0034] As described above, based on the structure of this invention, when vehicle 1 experiences a side collision, the bending point of the door can be limited to the vicinity of the front end 94 of the extension 91 of the handle reinforcement member 9. Therefore, by extending the front end 94 of the extension 91 to a position forward of the middle part of the door body of the door 2, the bending point can be generated in the front half of the door body away from the vehicle seat 5, thereby improving the protection performance for the occupant 6 and eliminating safety hazards.

[0035] However, this utility model is not limited to the embodiments described above, and can be applied and modified in various ways.

[0036] The above embodiments are illustrated by taking the application of the present invention to the left rear door of a vehicle 1 equipped with four doors 2 (front, rear, left, and right) as an example. However, the present invention is not limited to this. Any one of the left front door, right front door, left rear door, and right rear door of the vehicle 1 can adopt the structure described in the above embodiments.

[0037] Furthermore, the above embodiment illustrates a structure in which the handle reinforcement member 9 is joined to the upper door reinforcement member 8, but the present invention is not limited thereto. For example, the upper door reinforcement member 8 and the handle reinforcement member 9 may also be configured as a single unit.
