The present invention is a divisional application of an invention having an application date of 2014, 8/29, an application number of 201410448604.2, and an invention name of "front grill support structure".
Technical Field
The present invention relates to a front grille support structure for supporting a grille at a front portion of a vehicle body.
Background
Generally, a front frame of a vehicle body is provided as a partition frame at a front portion of the vehicle, and a device such as a radiator is generally mounted on the front frame. A radiator grill, a bumper, and the like are attached to the front of the vehicle body front frame.
As a mounting structure for mounting a radiator grill, a bumper, and the like to a front frame of a vehicle body, there are various mounting methods. For example, the radiator grill may be attached to an upper member of the front frame of the vehicle body via a bracket, or the like.
In such a structure in which the heat dissipation grill is attached by the bracket or the bracket, the heat dissipation grill tends to fall by gravity or to rotate about the attachment point of the bracket or the bracket. Therefore, it is desired to design an attachment structure in which the attachment work of the grille to the front frame of the vehicle body is simple and the grille after attachment is stably held, while overcoming such a problem.
Disclosure of Invention
The present invention has been made in view of the above problems, and an object of the present invention is to provide a front grille support structure that can attach a grille to a vehicle body side with a simple structure and simple work and can ensure that the grille after attachment is stably held.
In order to achieve the above object, the present invention provides the following technical solutions.

According to claim 2 of the present invention, in claim 1, it is preferable that the front grille is fastened to the front grille support at least two fastening points, the front grille support is supported by the front grille support member at least one support point, and the at least two fastening points and the at least one support point are arranged substantially on a straight line in the vehicle width direction, or the at least one support point is arranged ahead of a straight line connecting the at least two fastening points.
According to claim 3 of the present invention, in claim 1 or 2, it is preferable that an upper end portion of the front grid bracket support member is attached to the front grid bracket, a lower end portion of the front grid bracket support member is attached to the cross member, and the front grid bracket support member is disposed so as to be inclined such that the upper end portion of the front grid bracket support member is positioned in front of the vehicle with respect to the lower end portion of the front grid bracket support member.
According to claim 4 of the present invention, in claim 1, it is preferable that the front grille holder is disposed at a widthwise central portion of an upper member of the vehicle body front frame.
According to claim 5 of the present invention, it is preferable that, in claim 4, the front grille support member supports a widthwise central portion of the front grille support.
Effects of the invention
According to claim 1 of the present invention, since the front grille holder is attached to the front frame of the vehicle body, the front grille supported by the front grille holder at the front portion of the vehicle can be easily aligned with respect to the vehicle body side. And since the vehicle body front frame is a member for supporting the radiator, and has sufficient support strength, the front grill can be reliably supported.
In addition, since the front grill bracket support member supports the front grill bracket from below, a downward torque that the grill acts on the front grill bracket due to gravity can be resisted, and thus the front grill can be reliably supported by supporting the front grill bracket.
Further, since the front grille support member is attached to the cross member extending in the vehicle width direction, the weight of the grille can be received by the cross member having a high strength and being not easily bent, and the load on the front grille support can be effectively dispersed.

Detailed Description
Hereinafter, a front grill support structure according to an embodiment of the present invention will be described in detail with reference to the drawings.
Fig. 1 is a perspective view of a front grill support structure of the present invention with a front grill removed; FIG. 2 is a front schematic view of the front grille support construction of the present invention as viewed from the front of the vehicle; FIG. 3 is a side schematic view of the front grille support construction of the present invention viewed from the side of the vehicle; fig. 4 is a schematic plan view of the front grille support structure of the present invention as viewed from above the vehicle.
Fig. 1 to 4 show only a partial structure related to the front grille support structure in the vehicle. In the following description, unless otherwise specified, "front" and "rear" refer to a vehicle front and a vehicle rear with respect to a vehicle; the terms "up" and "down" refer to up and down relative to the vehicle; the "left-right direction" is the vehicle width direction.
As shown in fig. 1, a front vehicle body frame 1 is a frame member that is disposed at a front portion of a vehicle body of a vehicle such as an automobile and to which a radiator (not shown) is attached and held. The attachment of the front vehicle body frame 1 to the vehicle body side can be performed by a conventional technique. The vehicle front frame 1 is formed by an upper cross member 5, a lower cross member, and right and left vertical members 6, which substantially enclose a quadrangle.
A cross member 2 extending in the vehicle width direction is disposed in front of the vehicle body front frame 1. The left and right ends of the cross member 2 are fixed to left and right longitudinal members 6 in the vehicle body front frame 1. The cross member 2 is located below an upper cross member 5 of the vehicle body front frame.
A front grille support 3 is attached to a substantially central portion of an upper cross member 5 of the vehicle body front frame 1. The front grille support 3 is attached to the upper cross member 5 so as to extend in a cantilever manner forward from the vehicle body front frame 1. The mounting arm 3a extending from the front grill support 3 is mounted on the upper surface of the upper cross member 5 by, for example, bolt fastening or the like.
As shown in fig. 1, the front grille holder 3 is formed in a shape in which, for example, a central portion is flat and both left and right end portions are raised upward. The left and right bulging portions 3b, 3b extend continuously from the left and right mounting arms 3a and are parallel to each other. In addition, although not shown in the drawings, a hole or the like for weight reduction may be provided in the flat central portion.
The front grille holder 3 has grille fastening through holes P1 and P2 formed at both left and right ends thereof, respectively, and a support member attachment through hole P3 formed at a substantially central position of the flat portion. The front grill is fastened to the front grill bracket 3 by engagement of bolts (not shown) with the grill fastening through holes P1 and P2. In the fastened state, the front grille covers the front grille bracket 3, the cross member 2, and the like from above and in front. P1 and P2 are also referred to as "fastening points" in some cases, and P3 is also referred to as "support points" in some cases.
By configuring the front grille support 3 in a shape in which the center is flat and the left and right ends are raised, the support rigidity for the front grille can be improved, and the front grille support 3 itself is less likely to deform under the weight of the front grille.
The front grill support 3 may be made of metal such as aluminum alloy or resin.
A front grill support member 4 is provided for the front grill support 3. The front grid support member 4 is a rigid member made of metal or resin. The front grill support member 4, specifically, the upper end portion thereof is fastened to the front grill support 3 by bolts or the like from below the front grill support, so that the front grill support member 4 supports the front grill support 3 from below. This can prevent the front grille holder 3 from deforming downward by the weight of the front grille and moving the front grille downward, and therefore, the appearance of the vehicle body can be maintained without causing a large joint between the front grille and the hood or headlight.
The lower end portion of the front grill support member 4 is fixed to a substantially central position in the left-right direction of the cross member 2 by screw fastening. As shown in fig. 1, the upper surface of the cross member 2 is fixed at the center in the left-right direction.
As shown in fig. 1 and 2, the front grille holder support member 4 has a shape in which a triangular plate-like member is bent at substantially 90 degrees, and has a width in the left-right direction that increases toward the lower portion. With this configuration, the support stability of the front grille support member 4 can be improved, and the load acting on the front grille support member 4 can be uniformly distributed to the cross member 2, thereby reducing the stress concentration on the cross member 2.
The front grill support member 4 includes a standing wall 4a and a beam engagement wall 4 b. Reinforcing ribs 4c are formed on the rising wall 4a from top to bottom. The reinforcing ribs 4c can increase the strength of the front grille holder support member 4 in the vertical direction, and therefore, even a heavy front grille or the like can be reliably supported.
As shown in fig. 3, the front grill holder support member 4, in particular, the rising wall 4a thereof is formed to be inclined obliquely forward so that the upper end portion is located forward of the lower end portion. Accordingly, when the front grill is lowered by gravity and a downward-rearward rotational moment acts on the front grill support, the forward-inclined front grill support member 4 supports the front grill support in the direction opposite to the rotational moment, thereby improving the support efficiency.
In order to further support the front grille support with a small support force, as shown in fig. 4, a support point P3 of the front grille support member with respect to the front grille support may be arranged forward of the left and right front grille mounting through holes (also referred to as fastening points) P1 and P2. That is, the support point P3 is located forward of an imaginary line L extending in the vehicle width direction connecting the fastening points P1, P2. By providing the fastening points P1 and P2 of the front grille and the support point P3 of the front grille support in this manner, if the mounting position of the front grille support 3 on the upper cross member 5 is a fulcrum, the arm of force of the downward-upward support force of the front grille support member 4 can be made longer than the arm of force of the gravity of the front grille, and therefore, the balance can be achieved between the smaller support force and the moment of the gravity of the front grille. Of course, the fastening points P1, P2 and the support point P3 may be arranged on the same imaginary line extending in the vehicle width direction.
One embodiment of the present invention has been described above. The technical scheme of the invention is summarized as follows.
The present invention is a front grille support structure for supporting a front grille of a vehicle, including at least: a front grille support 3 attached to the vehicle body front frame 1 and supporting a front grille (not shown) at the front of the vehicle; a cross member 2 that is attached to the vehicle body front frame 1 (specifically, the upper cross member 5 thereof) from the front and extends in the vehicle width direction; and a front grill support member 4 that is mounted on the cross member 2 and supports the front grill support 3 from below.
Since the front grille holder 3 is attached to the vehicle body front frame 1, the front grille supported by the front grille holder 3 at the front of the vehicle can be easily aligned with the vehicle body side. And since the vehicle body front frame 1 is a member for supporting the radiator, and has sufficient support strength, the front grill can be reliably supported.
In addition, since the front grill support member 4 supports the front grill support 3 from below, a downward torque of the grill acting on the front grill support 3 due to gravity can be resisted, and thus the front grill can be reliably supported by supporting the front grill support 3.
Further, since the front grille support member 4 is attached to the cross member 2 extending in the vehicle width direction, the weight of the grille can be received by the cross member 2 having a high strength and being not easily bent, and the load on the front grille support 3 can be effectively dispersed.
In the front grille support structure of the present invention, it is preferable that the front grille is fastened to the front grille support 3 at least two fastening points P1, P2, the front grille support 3 is supported by the front grille support member 4 at least one support point P3, and the at least two fastening points P1, P2 and the at least one support point P3 are arranged substantially on a straight line in the vehicle width direction, or the at least one support point P3 is arranged forward of a straight line connecting the at least two fastening points P1, P2.
Thus, the front grill support member 4 and the cross member 2 can effectively support the front grill 3 with a small support force, and further support the front grill. In particular, when the support point P3 is disposed forward of the straight line connecting the two fastening points P1 and P2, the moment arm at the support point P3 is longer than the mounting position of the front grille support 3 to the vehicle body front frame 1 (corresponding to the fulcrum of the cantilever beam), and therefore the front grille support 3 and the front grille mounted thereon can be supported with a smaller force.
In the front grille support structure of the present invention, it is preferable that the upper end portion of the front grille support member 4 is attached to the front grille support 3, the lower end portion of the front grille support member 4 is attached to the cross member 2, and the front grille support member 4 is disposed so as to be inclined such that the lower end portion of the front grille support member 4 is positioned in front of the vehicle with respect to the upper end portion of the front grille support member.
Since the front grille holder support member 4 is disposed so as to be inclined such that the lower end portion thereof is positioned forward of the vehicle with respect to the upper end portion thereof, it is possible to more effectively support the downward and rearward rotational moment of the front grille due to gravity acting on the front grille holder 3.
In the front grille support structure of the present invention, it is further preferable that the front grille support 3 is disposed in the widthwise central portion of the upper cross member 5 of the vehicle body front frame 1. Thus, the front grille can be kept in balance, and only the front grille holder needs to be arranged at one central part.
In the front grille support structure of the present invention, it is further preferable that the front grille support member 4 supports the widthwise central portion of the front grille support 3. Thus, the front grill can be supported in a balanced and efficient manner.
While the embodiment of the front grill support structure has been described above, the present invention is not limited thereto, and various modifications can be made within the scope of the claims. For example, in the above description, the front grille support 3 and the vehicle body front frame 1, the front grille and the front grille support 3, the front grille support 3 and the front grille support member 4, and the front grille support member 4 and the cross member 2 are all connected by a screw structure, but these connection portions may be connected by other connection methods such as welding.
In the above description, the front grille support member 4 has a triangular shape as a whole, but may have another shape as long as it can support the front grille support and transmit the force from the front grille support to the cross member 2.
In the above description, the case where two fastening points P1, P2 and one support point P3 are provided has been described as an example, but the number of fastening points and support points is not limited to this, and may be added as appropriate.
As described above, the grille support structure of the present invention is applicable to various vehicle body structures having a frame member and a cross member.
