Description

Technical Field

[0001] The present invention relates to the field of vehicle parts, and in particular to a front bumper bracket assembly. Background Art

[0002] The front bumper bracket is an important connector for the front bumper assembly. The Z-axis strength of the bracket directly affects the fitting clearance around the front bumper. At the same time, the X-axis strength of the front bumper bracket directly affects pedestrian protection during a collision.

[0003] The bracket has strong X-direction strength, so the front bumper cannot collapse inward during a collision, and the pedestrian protection requirements cannot be met; the X-direction strength and Z-direction strength are also weak, so the bracket cannot support the front bumper in the Z direction, causing the front bumper to fall down, and cannot meet the fitting clearance requirements around the front bumper; that is, the current front bumper bracket strength cannot achieve Z-direction strengthening while meeting the X-direction weakening requirements.

[0004] Therefore, in order to solve the above problems, a front bumper bracket assembly is needed, which can strengthen the strength of the front bumper bracket in the Z direction while meeting the requirements of weakening the strength in the X direction. Summary of the Invention

[0005] In view of this, an object of the present invention is to overcome the defects in the prior art and provide a front bumper bracket assembly that can strengthen the front bumper bracket in the Z direction while meeting the requirements of weakening the front bumper bracket in the X direction.

[0012] Furthermore, the front bumper has an energy absorption box, and the second connecting member is integrated with the energy absorption box;

[0013] The left end of the Y direction of the Z-direction top surface of the energy absorption box extends upward and bends rightward to form a left limiting slide groove, and the right end of the Y direction of the Z-direction top surface of the energy absorption box extends upward and bends leftward to form a right limiting slide groove. The left limiting slide groove, the right limiting slide groove and the Z-direction top surface of the energy absorption box together form a slide rail with a cross section approximately in the shape of a "C";

[0014] The sliding portion includes a left sliding portion that is slidably limited by the left limiting sliding groove and a right sliding portion that is slidably limited by the right limiting sliding groove.

[0015] Furthermore, the first connecting member includes a functional plate parallel to the top surface of the energy absorption box in the Z direction, and the left end of the functional plate in the Y direction protrudes to the left to form a left sliding portion, and the left sliding portion extends into the slot of the left limiting slide along the Y direction and has the X-direction freedom and is limited in the Z direction by the left limiting slide, and the right end of the functional plate in the Y direction protrudes to the right to form a right sliding portion, and the right sliding portion extends into the slot of the right limiting slide along the Y direction and has the X-direction freedom and is limited in the Z direction by the right limiting slide.

[0016] Furthermore, the bottom end of the fixing portion in the Z direction is vertically connected to the horizontal center of the function board, and the horizontal center of the function board is the intersection of the center line of the function board in the Y direction and the center line of the function board in the X direction.

DETAILED DESCRIPTION

[0030] Figure 1This is a structural schematic diagram of the present invention. As shown in the figure, the X direction is the length direction of the vehicle when this solution is assembled on the vehicle, the front and back correspond to the front and back of the vehicle in the X direction when the vehicle is moving, the Z direction is the height direction of the vehicle when this solution is assembled on the vehicle, the up and down correspond to the up and down of the vehicle in the Z direction, the Y direction is the width direction of the vehicle when this solution is assembled on the vehicle, and the left and right correspond to the left and right of the vehicle in the Y direction when the vehicle is moving, which will not be repeated here; the front bumper bracket assembly in this embodiment includes a front bumper bracket main body 1 and a front bumper 4 connecting component, the connecting component includes a first connecting member 2 assembled on the front bumper bracket main body 1 and a second connecting member 3 assembled on the front bumper 4, and the first connecting member 2 and the second connecting member 3 are assembled with X-direction freedom. This solution can enable the existence of X-direction freedom between the front bumper bracket body 1 and the front bumper 4 through the use of a connecting component. The X-direction freedom can be achieved by sliding, swinging or a step-by-step limiting structure, etc. It is preferable to achieve the function of having X-direction freedom between the front bumper bracket body 1 and the front bumper 4, which will not be repeated here. Of course, the front bumper bracket body 1 and the front bumper 4 are connected in the Y and Z directions to ensure the structural strength requirements, which can enable the front bumper bracket strength to be strengthened in the Z direction while meeting the requirements of weakening in the X direction.

[0031] In this embodiment, the first connector 2 has a slide rail extending along the X-direction, and the second connector 3 has a sliding portion that can be driven to slide on the slide rail in the X-direction; alternatively, the second connector 3 has a slide rail extending along the X-direction, and the first connector 2 has a sliding portion that can be driven to slide on the slide rail in the X-direction. This solution uses a sliding mechanism to allow the first and second connectors 2 and 3 to have freedom in the X-direction, which is more conducive to collision collapse and pedestrian protection.

[0032] In this embodiment, the second connector 3 includes a slide rail extending along the X-direction, and the first connector 2 includes a sliding portion driven along the slide rail to slide along the X-direction. The first connector 2 is restrained by the slide rail in the Y-direction and in the Z-direction. This arrangement of the slide rail on the second connector 3 improves sliding stability. Due to factors such as gravity, a more stable bottom connection can better constrain the first connector 2 from moving in a predetermined manner in the X-direction, thereby improving the effectiveness of the structure.

[0033] In this embodiment, the first connector 2 is fixed to the front bumper bracket body 1, and the second connector 3 is fixed to the front bumper 4. This solution adopts a dual-fixed connection method, so that the front bumper 4 and the front bumper bracket have X-direction freedom only at the junction of the first connector 2 and the second connector 3, further limiting the collapse position and facilitating pedestrian protection. Of course, the installation method of the first connector 2 and the second connector 3 at their respective positions can also be selected according to specific circumstances, such as a movable connection with freedom, which will not be elaborated here.

[0034] In this embodiment, the bottom portion of the front end of the front bumper support body 1X protrudes downward along the Z direction to form an assembly end 6. The first connector 2 has a fixing portion 7 fixed to the front end surface of the assembly end 6X. As shown in the figure, the first connector 2 is fixed to the front end surface of the assembly end 6X by the fixing portion 7. Furthermore, the fixing method relies on connecting nails inserted through the fixing portion 7 and fixed to the assembly end 6, which improves the assembly strength of the first connector 2 on the front bumper support body 1. Compared with fixing methods such as pin connection and welding, it can ensure that the connection point will not crack or shift in the event of a head-on collision or side collision, and improve the structural strength of the first connector 2 and the front bumper support body 1 after the integration. Of course, the first connector 2 can also be arranged on the Y-direction side of the front bumper support body 1 to perform the same connecting function. This will not be repeated here. The upper and lower arrangement configuration of this solution makes the connection structure at this location more compact. At the same time, this location can also provide support and lifting for the bumper, improving the reliability of the front bumper 4 assembly on the vehicle.

[0035] In this embodiment, the front bumper 4 has an energy absorption box 5, and the energy absorption box 5 is generally arranged in two on the left and right sides in the Y direction. In this solution, one of them is taken as an example. In actual use, the front bumper bracket body 1 and the front bumper 4 connecting assembly are two sets in a one-to-one correspondence with the energy absorption box 5, which will not be described in detail here. The second connecting member 3 forms an integral part with the energy absorption box 5;

[0036] Furthermore, the left end of the Y direction of the top surface of the energy absorption box 5Z extends upward and bends to the right to form a left limiting slide groove 8, and the right end of the Y direction of the top surface of the energy absorption box 5Z extends upward and bends to the left to form a right limiting slide groove 9. The left limiting slide groove 8, the right limiting slide groove 9 and the top surface of the energy absorption box 5Z are surrounded to form a slide rail with a cross section approximately in the shape of a "C"; as shown in the figure, the second connecting member 3 is integrally formed on the top surface of the energy absorption box 5, which also plays a role in improving the structural strength of this part.

[0037] The sliding part includes a left sliding part 10 which is slidably limited by the left limiting slide groove 8 and a right sliding part which is slidably limited by the right limiting slide groove 9 (not shown in the figure, its structure is the same as the left sliding part 10, only the layout position is different).

[0038] In this embodiment, the first connecting member 2 includes a functional plate 11 parallel to the top surface of the energy absorption box 5 in the Z direction, and the left end of the functional plate 11 in the Y direction protrudes to the left to form a left sliding portion 10, and the left sliding portion 10 extends along the Y direction into the notch of the left limiting slide 8 and has the X-direction freedom and is limited along the Z direction by the left limiting slide 8, and the right end of the functional plate 11 in the Y direction protrudes to the right to form a right sliding portion, and the right sliding portion extends along the Y direction into the notch of the right limiting slide 9 and has the X-direction freedom and is limited along the Z direction by the right limiting slide 9. As shown in the figure, the left limiting groove 8 is recessed downward along the Z direction to form a left front limiting rib and a left rear limiting rib that limit the left sliding part 10 in the X direction. The left front limiting rib and the left rear limiting rib are not strictly strong limiting ribs, and are only used to limit the left sliding part 10 to the preset position in the left limiting groove 8. The right limiting groove 9 is recessed downward along the Z direction to form a right front limiting rib and a right rear limiting rib that limit the right sliding part in the X direction. The right front limiting rib and the right rear limiting rib are not strictly strong limiting ribs, and are only used to limit the right sliding part to the preset position in the right limiting groove 9, so that the front bumper 4 will not shake under non-collision conditions, thereby improving the protective effect.

[0039] In this embodiment, the Z-axis bottom end of the fixing portion 7 is perpendicularly connected to the horizontal center of the functional panel 11, which is the intersection of the Y-axis and X-axis of the functional panel 11. As shown in the figure, the configuration of the first connecting member 2 ensures that the center of the first connecting member 2 serves as the intermediate force transmission element regardless of the direction of the collision. This improves the reliability of force transmission, effectively ensures the integrity of the force transmission chain, and enhances the effectiveness of the preset protective function.

[0040] In this embodiment, the functional base plate has a left stopper 12 at its left end in the Y direction for engaging with the right end surface of the left stopper chute 8 in the Y direction. The functional base plate has a right stopper 13 at its right end in the Y direction for engaging with the left end surface of the right stopper chute 9 in the Y direction. The functional base plate is restrained by the slide rail in the Y direction by the left stopper 12 and the right stopper 13. The arrangement of the left stopper 12 and the right stopper 13 further enhances the collapse and movement of the first connector 2 and the second connector 3 in the predetermined X direction, ensuring pedestrian safety.

[0041] In this embodiment, the left stopper 12 and the right slider are located on the same side of the function panel 11 in the X direction, while the right stopper 13 and the left slider 10 are located on the other side of the function panel 11 in the X direction. The line connecting the left and right stopper 12, 13 intersects the line connecting the left and right sliders 10 at the horizontal center of the function panel 11. As shown in the figure, the left stopper 12 and the right stopper 13 are arranged diagonally, and the left and right sliders 10 are arranged diagonally. A left functional notch 14 is defined between the left stopper 12 and the left slider 10, and a right functional notch 15 is defined between the right stopper 13 and the right slider. These provide protection against collisions in corresponding directions, thereby enhancing pedestrian safety.

[0042] In this embodiment, a lower reinforcing rib is arranged at the bottom of the first connecting member 2 in the Z direction, and an upper reinforcing rib is arranged at the top of the first connecting member 2 in the Z direction, so as to further improve the structural strength of the first connecting member 2 and meet the established collision requirements.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
