Description

Technical Field

[0001] This utility model belongs to the field of automotive design technology, specifically relating to an overlapping structure of the front body water tank crossbeam. Background Technology

[0002] In automotive design, the radiator mounting beam at the front of the vehicle is crucial for ensuring the overall strength, stability, and safety of the vehicle's front structure. For example... Figure 3 As shown, the design of a traditional radiator mounting beam typically involves welding the headlight bracket portions 2' at both ends of the radiator beam 1' to the pillars inside the vehicle body. Then, the radiator beam 1' is connected to the headlight bracket portions 2' on both sides using bolts and nuts. Finally, the end of the headlight bracket portion 2' closest to the front shock absorber mounting assembly 3' is overlapped to the top of the front shock absorber mounting assembly 3' via a connecting piece 4' and secured with screws.

[0003] Although this traditional design can meet basic functional requirements to some extent, it still has the following problems in practical applications: The installation process of the overlapping piece requires the operator to align the overlapping piece with the corresponding position on the front shock absorber mounting assembly, so that the mounting hole on the overlapping piece corresponds to the threaded hole on the front shock absorber mounting assembly, so that the screw can limit and fix the overlapping piece on the front shock absorber mounting assembly. This results in low assembly efficiency. Moreover, the overlapping method of limiting and fixing the overlapping piece with screws has insufficient overlapping strength. With the vibration during vehicle operation and the passage of time, the overlapping point is prone to loosening, affecting the stability of the entire structure. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an overlapping structure for the front vehicle body water tank crossbeam, thereby solving the problems of low assembly efficiency and insufficient overlapping strength of existing water tank crossbeams.

[0005] The technical solution adopted by this utility model is as follows: an overlapping structure of a front vehicle water tank crossbeam, including an integrated support crossbeam, wherein overlapping components are provided at both ends of the integrated support crossbeam.

[0006] The overlapping assembly includes an overlapping portion and a detachable connector; the overlapping portion is disposed at the end of the integrated support beam;

[0007] The front shock absorber mounting assembly includes two units, each with an overlap groove. The overlap portions at both ends of the integrated support beam are respectively engaged in the overlap grooves of the two front shock absorber mounting assemblies. The overlap portions are detachably connected to the overlap grooves via detachable connectors.

[0008] Furthermore, the front shock absorber mounting assembly includes a limiting part, and the overlapping groove is formed at the top of the limiting part of the front shock absorber mounting assembly. The front end of the overlapping groove is open for inserting the overlapping part, and the shape of the overlapping groove is adapted to the overlapping part.

[0009] Furthermore, the detachable connector includes a bolt and a nut; an installation through hole is provided on the overlapping part along the width direction of the overlapping part, and installation holes are provided on both sides of the overlapping groove that are in contact with the overlapping part. The installation holes are set corresponding to the installation through holes. The bolt thread passes through the installation hole and the installation through hole, penetrating the overlapping part of the integrated support beam and the limiting part of the front shock absorber mounting assembly, and is threadedly connected to the nut.

[0010] Furthermore, the integrated support beam has an integral wrap-around structure and an internal cavity.

[0011] The beneficial effects of this utility model are:

[0012] By integrating the water tank crossbeam and the headlight brackets located at both ends of the water tank crossbeam into an integrated support crossbeam, the overall rigidity and stability of the entire front end are enhanced. By setting overlapping components at both ends of the integrated support crossbeam, the overlapping parts in the overlapping structure are engaged with the overlapping slots opened on the front shock absorber mounting assembly, realizing rapid positioning of the overlapping parts, reducing the requirements for operational precision, thereby improving assembly efficiency. In addition, the detachable connectors make the connection between the integrated support crossbeam and the front shock absorber mounting assembly more secure and increase the overlapping strength.

[0023] Example 1:

[0024] like Figures 1-2 As shown, a front vehicle body water tank crossbeam overlap structure includes an integrated support crossbeam 1, with overlap components at both ends of the integrated support crossbeam 1. In this embodiment, the integrated support crossbeam 1 integrates a water tank crossbeam and headlight bracket portions located at both ends of the water tank crossbeam. The water tank crossbeam portion of the integrated support crossbeam 1 is used to install the front water tank, and the headlight bracket portion of the integrated support crossbeam 1 is used to weld to the pillars inside the vehicle body.

[0025] In this embodiment, the integrated support beam 1 has several screw holes (not shown in the figure) for screwing with the column. In addition to providing a mounting point for the water tank, the entire integrated support beam 1 is also used to ensure the Y-direction support strength of the front of the car in a 25% offset collision, so as to provide better protection for the occupants in a collision.

[0026] The overlapping component includes an overlapping part 11 and a detachable connector; the overlapping part 11 is disposed at the end of the integrated support beam 1; the overlapping part 11 is fixedly connected to the end of the integrated support beam 1, and the overlapping part 11 has a rectangular structure and an internal cavity.

[0027] There are two front shock absorber mounting assemblies 2. Each front shock absorber mounting assembly 2 has an overlap groove 22. The overlap portions 11 at both ends of the integrated support beam 1 are respectively snapped into the overlap grooves 22 of the two front shock absorber mounting assemblies 2. The overlap portions 11 are detachably connected to the overlap grooves 22 by detachable connectors.

[0028] As a preferred embodiment, the front shock absorber mounting assembly 2 includes a limiting part 21, and the overlapping groove 22 is formed on the top of the limiting part 21 of the front shock absorber mounting assembly 2. The front end of the overlapping groove 22 is open for inserting the overlapping part 11, so that the overlapping part 11 can be inserted Z-shaped, making installation simple. The shape of the overlapping groove 22 is adapted to the overlapping part 11.

[0029] In this embodiment, both the overlapping portion 11 and the overlapping groove 22 are rectangular structures. A small gap is left between the two vertical surfaces of the overlapping portion 11 that are in contact with the overlapping groove 22 along its length and the corresponding groove wall of the overlapping groove 22, providing a gap for the upper part of the overlapping portion 11, making the upper part easier to install. The use of the overlapping portion 11 and the overlapping groove 22 in a matching manner, with the reserved small gap, makes the integrated support beam 1 easier and more convenient to install, reducing the difficulty of precise alignment and improving assembly efficiency. The rectangular structure has better positioning performance compared to other shapes. Through a precisely matched rectangular cross-section, it can be ensured that the overlapping portion 11 is accurately placed within the overlapping groove 22 of the front shock absorber mounting assembly 2, reducing assembly errors and improving the overall structural alignment. While the rectangular structure itself does not directly increase material strength, its regular shape helps to evenly distribute stress and avoid localized stress concentration, thereby increasing the overlapping strength. Simultaneously, the use of bolts 12 and nuts 13 for fastening provides sufficient clamping force without affecting assembly convenience, thus enhancing the stability and robustness of the entire overlapping structure.

[0030] As a preferred embodiment, the detachable connector includes a bolt 12 and a nut 13; an installation through hole 14 is provided on the overlapping part 11 along the width direction of the overlapping part 11, and installation holes 23 are provided on both sides of the overlapping groove 22 that are in contact with the overlapping part 11. The installation holes 23 are set corresponding to the installation through holes 14. The bolt 12 passes through the overlapping part 11 of the integrated support beam 1 and the limiting part 21 of the front shock absorber mounting assembly 2 through the installation holes 23 and the installation through holes 14, and is threadedly connected to the nut 13. Specifically, when the outer end face of the overlapping part 11 abuts against the inner groove wall of the overlapping groove 22, the installation holes 23 and the installation through holes 14 are relatively distributed, which facilitates the quick limiting of the overlapping part 11 and facilitates the bolt 12 to pass through the installation holes 23 and the installation through holes 14.

[0031] In this embodiment, two bolts 12 and two nuts 13 are provided at each overlapping groove 22. The two bolts 12 are spaced apart along the length of the overlapping portion 11. Specifically, a washer is fitted on the side of the bolt 12 facing the outer wall of the limiting portion 21 of the front shock absorber mounting assembly 2, and a washer is also fitted on the side of the nut 13 facing the outer wall of the limiting portion 21 of the front shock absorber mounting assembly 2. Using bolts 12 and nuts 13 as detachable connectors, and cooperating with mounting holes 14 and 23, facilitates quick installation and disassembly, further improving assembly efficiency.

[0032] As a preferred embodiment, the integrated support beam 1 has a one-piece, encircling structure with an internal cavity. In this embodiment, several reinforcing ribs are fixedly arranged in an array within the cavity of the integrated support beam 1. The design of the integrated support beam 1 reduces the welding requirements between multiple components in traditional designs, lowers the complexity of the manufacturing process, and improves production efficiency. The design of the integrated support beam 1 makes the entire front structure more integrated, which helps to distribute stress and improve the overall structural strength and stability. The design of the integrated support beam 1 reduces the welding requirements between multiple components in traditional designs, lowers the complexity of the manufacturing process, and improves production efficiency.

[0033] The present invention has been described in detail above. The specific embodiments are provided only to help understand the method and core idea of ​​the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
