The vehicle door structure includes a vehicle door; a cross member disposed in the door and extending in a front-rear direction of a vehicle, wherein the cross member has a convex portion including an upper portion, a side portion, and a lower portion, the side portion being connected between the upper portion and the lower portion; two vertical beams disposed in the door and extending in an up-down direction of the vehicle, wherein the two vertical beams are connected to the upper portion and the lower portion, respectively; and a back plate having two contact surfaces extending in a width direction of the vehicle and abutting the upper portion and the lower portion in the up-down direction, respectively, inside the convex portion.
Description
Technical Field
The present invention relates to a vehicle member structure, and more particularly, to a vehicle door structure.
Background
In a door of a vehicle, vertical beams are provided above and below a cross beam, respectively, and the vertical beams are connected to a convex portion of the cross beam. When the door is subjected to a side impact at the vertical beam, the convex portion of the cross member is easily deformed by a load from the vertical beam, possibly resulting in safety concerns such as structural damage. To improve this problem, some doors have a back panel that is attached to the cross member and corresponds to the raised portion. However, the joint surface between the back plate and the cross beam often extends in the vertical direction to be parallel to the direction in which the load from the vertical beam acts, and it is difficult to provide a sufficient supporting effect against the load. Therefore, it is necessary to improve the door structure to improve the safety of the vehicle.
SUMMERY OF THE UTILITY MODEL
The utility model provides a vehicle door structure, which can prevent a convex part of a cross beam from deforming due to the load from a vertical beam.
The utility model provides a vehicle door structure, comprising a vehicle door; a cross member disposed in the door and extending in a front-rear direction of a vehicle, wherein the cross member has a convex portion including an upper portion, a side portion, and a lower portion, the side portion being connected between the upper portion and the lower portion; two vertical beams disposed in the door and extending in an up-down direction of the vehicle, wherein the two vertical beams are connected to the upper portion and the lower portion, respectively; and a back plate having two contact surfaces extending in a width direction of the vehicle and abutting the upper portion and the lower portion in the up-down direction, respectively, inside the convex portion.
In an embodiment of the utility model, the two contact surfaces overlap the two vertical beams when viewed along the up-down direction.
In one embodiment of the present invention, the cross beam includes a first beam having an upper section, a side section, and a lower section, a second beam coupled to the upper section and the side section, and a third beam separate from the second beam and coupled to the lower section and the side section.
In view of the above, in the vehicle door structure of the utility model, the contact surface of the back plate extends in the width direction of the vehicle, so that when the vehicle door structure receives a side impact at the vertical beam, the contact surface is substantially perpendicular to the acting direction (i.e., the up-down direction) of the load from the vertical beam. Accordingly, the contact surface can provide a sufficient supporting effect to the convex portion of the cross member to resist the load, avoiding deformation of the convex portion of the cross member by receiving the load from the vertical beam. Therefore, the vehicle door structure can improve the structural stability and safety of the vehicle.
In order to make the aforementioned and other features and advantages of the utility model more comprehensible, embodiments accompanied with figures are described in detail below.

Detailed Description
Fig. 1 is a schematic sectional view of a vehicle door structure according to an embodiment of the present invention. Fig. 2 is a schematic cross-sectional view of the cross beam, back plate and partial vertical beam of fig. 1. Fig. 3 is a cross-sectional view of the beam and backing plate of fig. 1. Referring to fig. 1 to fig. 3, the vehicle door structure 100 of the present embodiment includes a vehicle door 110, a cross beam 120, two vertical beams 130, and a back panel 140. The cross member 120 is disposed inside the door 110 and extends in the front-rear direction of the vehicle (i.e., the direction parallel to the axial direction X). The beam 120 has a protrusion 120a, the protrusion 120a includes an upper portion 120a1, a side portion 120a2, and a lower portion 120a3, and the side portion 120a2 is connected between the upper portion 120a1 and the lower portion 120a 2. The two vertical beams 130 are disposed in the door 110 and extend in the vertical direction of the vehicle (i.e., the direction parallel to the axial direction Z). The two vertical beams 130 are connected to the upper portion 120a1 of the convex portion 120a and the lower portion 120a3 of the convex portion 120a, respectively. The back plate 140 has two contact surfaces 140a, the two contact surfaces 140a extending in the width direction of the vehicle (i.e., the direction parallel to the axial direction Y) and abutting the upper portion 120a1 of the convex portion 120a and the lower portion 120a3 of the convex portion 120a, respectively, in the up-down direction inside the convex portion 120 a.
Under the above configuration, when the vehicle door structure 100 receives a side impact at the vertical beam 130, the contact surface 140a of the back plate 140 is substantially perpendicular to the acting direction of the load from the vertical beam 130 (i.e., the up-down direction). Accordingly, the contact surface 140a of the back plate 140 can provide a sufficient supporting effect to the convex portion 120a of the cross member 120 to resist the load, and prevent the convex portion 120a of the cross member 120 from being deformed by receiving the load from the vertical member 130. Therefore, the door structure 100 of the present embodiment can improve the structural stability and safety of the vehicle.
Fig. 4 is a partial enlarged view of the cross beam, back plate and vertical beam of fig. 2. Referring to fig. 2 and fig. 4, when viewed along the up-down direction, the two contact surfaces 140a of the back plate 140 are overlapped with the two vertical beams 130, and the overlapping region R is shown in fig. 4. In this arrangement, the load from the vertical beam 130 can directly act on the contact surface 140a, so that the contact surface 140a can effectively resist the load, suppressing deformation of the convex portion 120a of the lateral beam 120.
The composition of the beam 120 of the present embodiment will be specifically described below. In the present embodiment, the cross beam 120 includes a first beam 122, a second beam 124, and a third beam 126, and the first beam 122 has an upper section 1221, a side section 1222, and a lower section 1223. The second beam 124 is coupled to the upper section 1221 of the first beam 122 and the side sections 1222 of the first beam 122, and the third beam 126 is spaced apart from the second beam 124 and coupled to the lower section 1223 of the first beam 122 and the side sections 1222 of the first beam 122. It is understood that the upper portion 120a1 of the protrusion 120a is formed by at least a portion of the upper section 1221 of the first beam 122 and at least a portion of the second beam 124, and the lower portion 120a3 of the protrusion 120a is formed by at least a portion of the lower section 1223 of the first beam 122 and at least a portion of the third beam 126. The contact surfaces 140a of the back plate 140 support the second beam 124 and the third beam 126, respectively, so that the second beam 124 and the third beam 126 can resist the load from the vertical beam 130 and suppress deformation of the convex portion 120a of the lateral beam 120.
If the second beam 124 and the third beam 126 are integrally formed, the integrally formed structure needs to be precisely matched in size and shape with the first beam 122 so that the second beam 124 and the third beam 126 can be smoothly combined with the first beam 122. Therefore, the second beam 124 and the third beam 126 are disposed to be separated from each other rather than integrally formed as described above, so that the second beam 124 and the third beam 126 are more easily and smoothly combined with the first beam 122. That is, the machining accuracy requirements of the second beam 124 and the third beam 126 may be reduced.
In summary, in the vehicle door structure of the present invention, the contact surface of the back plate extends in the width direction of the vehicle, so that when the vehicle door structure receives a side impact at the vertical beam, the contact surface is substantially perpendicular to the acting direction (i.e., the up-down direction) of the load from the vertical beam. Accordingly, the contact surface can provide a sufficient supporting effect to the convex portion of the cross member to resist the load, avoiding deformation of the convex portion of the cross member by receiving the load from the vertical beam. Therefore, the vehicle door structure can improve the structural stability and safety of the vehicle.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
