Description

Technical Field

[0001] The utility model relates to the field of building parts, in particular to a front bumper mounting structure. Background Art

[0002] The front bumper of a flat-head car model cannot be directly connected and fixed to the fender due to the limitations of its shape and layout space. During installation, the surface difference between the front bumper and the fender and door panel cannot be guaranteed. In order to solve this problem, our company has designed a front bumper mounting structure for a flat-head small truck model as shown in application number CN202321789752.1, which includes a number of brackets and a number of limiting columns. The brackets are connected to both sides of the front bumper, and each bracket is provided with a snap-in cavity and an Ω-shaped snap-in groove; the limiting columns are T-shaped, including a snap-in portion and a limiting portion. The snap-in portion is snapped into the snap-in groove, and the limiting portion is located in the snap-in cavity. Before the front bumper is installed, the limiting columns are used to position the body-in-white in the X-axis and Y-axis directions to improve the installation accuracy of the front bumper when it is installed on the body.

[0003] However, in actual applications, it is found that the front bumper still has installation errors along the Z axis, and the above-mentioned installation structure cannot further position the front bumper in the Z axis direction. Therefore, there is still a need for an installation structure that can further improve the installation accuracy of the front bumper. Utility Model Content

[0004] The utility model aims to provide a front bumper mounting structure to solve the problem that the front bumper cannot be positioned from the Z axis.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a front bumper mounting structure, including a mounting bracket, a limiting column is provided on the mounting bracket, a clamping cavity and a clamping groove are provided on the mounting bracket, the limiting column includes a clamping portion and a limiting portion distributed in a T shape, the width of the limiting portion is greater than the width of the clamping portion, the limiting portion is located in the clamping cavity, the clamping portion is located in the clamping groove, and the side wall of the clamping groove is fixed with a protrusion for limiting the limiting column; the mounting bracket is connected to the front bumper, and a clamping part is detachably connected to the mounting bracket, and the clamping part is clamped to the vehicle body.

[0006] The beneficial effects of this program are:

[0007] In this solution, the width of the front bumper is the Y-axis, the thickness of the front bumper is the X-axis, and the height of the front bumper is the Z-axis. Before installing the front bumper, the mounting bracket is connected to the front bumper. During installation, the clamping member and the limit post in this solution simultaneously connect the mounting bracket to the vehicle body. The limit post limits the mounting bracket's X- and Y-axis directions, while the clamping member limits the mounting bracket's Z-axis direction, effectively preventing installation errors along the Z-axis during front bumper installation.

[0008] In this solution, there is no relative rotation between the clamping member and the mounting bracket. Therefore, when the clamping member is used to limit the mounting bracket, the mounting bracket can be prevented from rotating, thereby further improving installation accuracy. Secondly, the clamping member and the limiting column in this solution simultaneously limit the mounting bracket. Therefore, when the mounting bracket is connected to the vehicle body, the mounting bracket can be further prevented from rotating, thereby preventing the front bumper from rotating, further improving the installation accuracy of the front bumper.

[0009] Furthermore, a slide groove is provided on the mounting bracket, and the extension direction of the slide groove is the same as the sliding direction of the limit column on the mounting bracket. One end of the clamping part is located in the slide groove and can slide along the slide groove; a limit block and a limit groove that cooperate with each other are provided between the lower clamping part and the mounting bracket, and one of the limit block and the limit groove is set on the lower clamping part, and the other is set on the mounting bracket.

[0010] The beneficial effect of this solution is that the cooperation between the limit block and the limit groove in this solution can limit the clip part, further prevent the clip part from falling off the mounting bracket, and ensure that the clip part can position the mounting bracket and the front bumper.

[0011] Furthermore, a limiting plate opposite to the clamping member is fixed at one end of the slide groove.

[0012] The beneficial effect of this solution is that the limiting plate limits the clamping member to prevent the clamping member from sliding off the sliding groove.

[0013] Furthermore, a guide groove is provided on a side of the slide away from the limiting plate, and the width of the guide groove on the side away from the limiting plate is greater than the width on the side close to the limiting plate.

[0014] The beneficial effect of this solution is that the provision of the guide groove can guide the installation of the clamping member, so that the clamping member can be installed better.

[0015] Furthermore, the bottom of the clamping member includes two lower clamping parts that can undergo elastic deformation, and the lower clamping parts are both against the mounting bracket.

[0016] The beneficial effect of this solution is that after the clip in this solution is installed on the mounting bracket, the two clip parts abut against the mounting bracket, increasing the friction between the clip parts and the mounting bracket, so a greater force is required to move the clip, so the clip can be prevented from falling from the mounting bracket when installing the front bumper.

[0017] Furthermore, a first connecting portion is provided on the mounting bracket, and the first connecting portion is clamped to the front bumper.

[0018] The beneficial effect of this solution is that the mounting bracket and the front bumper can be quickly preliminarily connected through the first connecting portion, and after the clamping, no relative movement occurs between the mounting bracket and the front bumper, which makes it convenient to use bolts to strengthen the connection strength between the two.

[0019] Furthermore, a plurality of first connection portions are provided, and all of the first connection portions are distributed in sequence along the height direction of the front bumper.

[0020] The beneficial effect of this solution is that the initial connection strength between the front bumper and the mounting bracket in this solution is better.

[0021] Furthermore, a locking piece is provided on the mounting bracket, which passes through the mounting bracket and connects the mounting bracket to the front bumper.

[0022] The beneficial effect of this solution is that the locking member further connects the front bumper and the mounting bracket, preventing the mounting bracket from falling off the front bumper.

[0023] Furthermore, a mounting seat is fixedly connected to the mounting bracket, and the locking piece passes through the mounting seat.

[0024] The beneficial effect of this solution is that the mounting seat can increase the contact area with the locking member and improve the mounting strength.

[0025] Furthermore, a reinforcing rib is fixed to a side of the mounting bracket facing away from the front bumper, and the reinforcing rib is fixed to the mounting seat.

[0026] The beneficial effect of this solution is that the connection between the reinforcing rib and the mounting seat can further improve the strength of the structure around the locking member and avoid damage to the mounting bracket. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Example

[0037] The embodiment is basically as follows Figure 1 、 Figure 2 and Figure 3 As shown, a front bumper mounting structure includes a mounting bracket 2, a limiting column 4 and a clamping seat 5 are provided on the mounting bracket 2, the width direction of the front bumper 1 is the Y axis, the thickness direction of the front bumper 1 is the X axis, and the height direction of the front bumper 1 is the Z axis. Figure 5 As shown, the mounting bracket 2 is provided with a limit seat 3, which includes a snap-in cavity and an Ω-shaped snap-in groove. The snap-in groove opens along the X-axis direction. Specifically, the snap-in groove opens forward. The mounting bracket 2 is provided with two notches, one of which is directly opposite the snap-in cavity and the snap-in groove. The limit post 4 is T-shaped and includes a snap-in portion 41 and a limit portion 42. The diameter of the limit portion 42 is larger than the diameter of the snap-in portion 41. The limit portion 42 is located in the snap-in cavity, and the snap-in portion 41 is located in the snap-in groove. Therefore, when the limit post 4 is installed, it slides into the snap-in groove along the X-axis direction. The side wall of the snap-in groove is integrally injection-molded with a protrusion 31. Specifically, after the limit post 4 is installed, the protrusion 31 is located in front of the limit post 4, limiting the limit post and preventing the limit post 4 from sliding forward.

[0038] The card holder 5 and the mounting bracket 2 are integrally injection molded. Figure 6 As shown, the connector 5 includes two L-shaped portions, located on the upper and lower sides of the other notch in the mounting bracket 2. The L-shaped portion includes a fixedly connected longitudinal portion 52 and a transverse portion 51. The longitudinal portion 52 is inclined from the end away from the mounting bracket 2 toward the end closer to the other L-shaped portion.

The distance between the left ends of the two lower clamping portions 61 is greater than the distance between the right ends, that is, the left ends of the lower clamping portions 61 are inclined in the direction of moving away from each other. The lower clamping portion 61 in this embodiment passes through the slide groove and abuts against the L-shaped portion. The lower clamping portion 61 in this solution is integrally injection-molded with a limiting block 64 toward the side wall of the transverse portion 51. A limiting groove 54 is provided on the transverse portion 51. The limiting block 64 in this embodiment is located in the limiting groove 54 and abuts against the transverse portion 51. The cooperation between the limiting block 64 and the limiting groove 54 can limit the clamping member 6. Since the lower clamping portion 61 can undergo elastic deformation, it can still slide along the slide groove after being subjected to a large force. The front side of the L-shaped portion is integrally injection-molded with a guide plate 53, combined with Figure 4 As shown, a guide groove is formed between the two guide plates 53 , and the width of the front end of the guide groove is greater than the width of the rear end, and guides the lower clamping portion 61 when it slides into the guide groove.

[0040] Several first connecting parts 23 are distributed along the side length direction on the front side of the mounting bracket 2. In this embodiment, the first connecting parts 23 and the mounting bracket 2 are injection molded as one piece. In actual implementation, the first connecting parts 23 are snap-fitted to the front bumper 1 to complete the preliminary connection between the mounting bracket 2 and the front bumper 1.

[0041] Several reinforcing ribs 21 and a plurality of mounting seats 22 are integrally injection-molded on the right side wall of the mounting bracket 2. The mounting seats 22 are connected to the reinforcing ribs 21. A locking member 7 is provided on the mounting seat 22. In this embodiment, the locking member 7 is a bolt. The locking member 7 passes through the mounting seat 22 and is connected to the mounting bracket 2 and the front bumper 1 via a matching nut.

[0042] The specific implementation process is as follows:

[0043] Before installing the front bumper 1 on the vehicle body, first pass the clamping portion 41 of the limiting column 4 through the notch and into the clamping slot to complete the installation of the limiting column 4. Then connect the front bumper 1 to the mounting bracket 2. When connecting, first clamp the mounting bracket 2 to the front bumper 1 through the first connecting portion 23, and then install the locking member 7 to complete the assembly of the front bumper 1 and the mounting bracket 2. Then install the clamping member 6 on the clamping seat 5. During installation, clamp the upper clamping portion 63 of the clamping member 6 to the vehicle body to complete the preliminary connection between the mounting bracket 2 and the vehicle body. After installation, the limiting column 4 limits the mounting bracket 2 in the X-axis and Y-axis directions, and the clamping member 6 limits the mounting bracket 2 in the Z-axis direction.
