[0026] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0027] An automobile upper longitudinal beam part according to an embodiment of the utility model will be described in detail below in conjunction with the accompanying drawings. Example

[0028] For easier understanding, see Figures 1 to 5 The utility model provides an embodiment of an upper longitudinal beam part of an automobile, comprising:

[0029] A main beam body 1, wherein the inner side surface of the main beam body 1 is provided with a first engaging groove 2 and a second engaging groove 3;

[0030] The inner wall of the first engaging groove 2 is fixedly mounted with a first sliding guide rail 4;

[0031] The inner wall of the second engaging groove 3 is fixedly mounted with a second sliding guide rail 5;

[0032] A first rubber strip 6 is slidably mounted in the first sliding guide rail 4;

[0033] A second rubber strip 7 is slidably mounted in the second sliding guide rail 5 .

[0034] It should be noted that the main beam body 1 is made by hot forming process to ensure that it has sufficient strength and rigidity. The main beam body 1 is designed with a precise inner side profile to meet the subsequent assembly requirements. On the inner side of the main beam body 1, the first engagement groove 2 and the second engagement groove 3 are respectively processed by precision machining technology. The groove size is precise to ensure the tight fit of subsequent accessories. The pre-made first sliding guide 4 and the second sliding guide 5 are fixed to the inner walls of the first engagement groove 2 and the second engagement groove 3 by welding or fasteners to ensure that the sliding guides are installed firmly and parallel. Rubber strips with good wear resistance and low friction coefficient are selected, cut to appropriate lengths, and then slide into the first sliding guide 4 and the second sliding guide 5 as shock-absorbing and buffering elements. The first sliding guide 4 and the second sliding guide 5 ensure that they have T-section slider tracks inside, so as to achieve smooth and reliable sliding fit with components that may be assembled in the future, and enhance the overall dynamic performance and adaptability.

[0035] In some embodiments, an adjustable connecting member 8 is respectively disposed at one end of the inner wall of the first engaging groove 2 and the second engaging groove 3 , and one end of the adjustable connecting member 8 is in an arc shape.

[0036] It should be noted that one end of the adjustable connector 8 has an arc-shaped structure to meet specific assembly requirements. These connectors are made by precision casting or machining, and then fixedly installed in the designated positions of the first engagement groove 2 and the second engagement groove 3.

[0037] In some embodiments, the side walls of the two adjustable connecting members 8 are respectively provided with a plurality of inner grooves 9 , and an elastic snap-fit ​​element 10 is fixedly mounted on one end of the inner wall of the plurality of inner grooves 9 .

[0038] It should be noted that a plurality of inner grooves 9 are provided on the side wall of the adjustable connector 8, and elastic snap-fit ​​elements 10 are installed one by one to ensure that they are securely fixed, thus laying a foundation for subsequent positioning and adjustment functions.

[0039] In some embodiments, a plurality of positioning pin grooves 11 are respectively disposed at the other end of the inner wall of the first engaging groove 2 and the second engaging groove 3 , and one end of a plurality of elastic snap elements 10 is movably connected to the inner wall of the corresponding positioning pin groove 11 .

[0040] It should be noted that a plurality of positioning pin grooves 11 are processed at the other end of the engaging groove to ensure that one end of the elastic snap element 10 can be flexibly snapped into these positioning pin grooves to achieve accurate positioning of the assembly.

[0041] In some embodiments, the side wall of the main beam body 1 is provided with two pairs of symmetrically arranged through holes 12 , and the two pairs of through holes 12 are aligned with the middle parts of the two adjustable connecting members 8 .

[0042] It should be noted that the assembly of the through-holes and the threaded elements is as follows: two pairs of symmetrically arranged through-holes 12 are drilled on the side wall of the main beam body 1 to ensure accurate alignment with the middle of the adjustable connector 8. Subsequently, the threaded element 13 is fixedly embedded in each adjustable connector.

[0043] In some embodiments, the two adjustable connecting members 8 are fixedly embedded with threaded elements 13, and the two through-holes 12 are rotatably equipped with fastening screws 14. The two fastening screws 14 are engaged with the inside of the two threaded elements 13 through their threaded parts, and the first sliding guide rail 4 and the second sliding guide rail 5 are designed with T-shaped slider tracks for sliding cooperation.

[0044] It should be noted that by screwing the fastening screw 14 into the through hole 12 and utilizing the threaded portion thereof to engage with the inside of the threaded element 13 , the fastening and adjustment of the entire assembly is completed, thereby ensuring the stability of the structure and the flexibility of adjustment.

[0045] Working principle: The first sliding guide rail 4 and the second sliding guide rail 5 are respectively installed in the first engagement groove 2 and the second engagement groove 3, and the first rubber strip 6 and the second rubber strip 7 are slidably installed therein, which together constitute a sliding damping system. The rubber strip not only reduces friction, but also improves the comfort and NVH (noise, vibration, and harshness) performance during driving. The adjustable connector 8 can adapt to different installation requirements through its arc-shaped structure, and the elastic snap element 10 installed in the inner groove 9 on its side wall provides preliminary positioning and adaptation functions. When the connector is correctly placed in the engagement groove, one end of the elastic snap element can enter the positioning pin groove 11 through a movable connection to achieve more precise position adjustment and locking, ensuring the stability of the structure. The two pairs of through-hole grooves 12 on the side wall of the main beam body are aligned with the adjustable connector 8. Through the use of the threaded element 13 and the fastening screw 14, the precise adjustment and final fastening of the component in three-dimensional space are achieved. The user can fine-tune the position of the connector by tightening or loosening the fastening screw according to actual needs to meet different installation conditions or compensate for the slight deformation that may occur due to long-term use. The T-shaped slider track design inside the first sliding guide rail 4 and the second sliding guide rail 5 not only ensures smooth interaction with potential sliding components, but also facilitates the subsequent installation or maintenance of modular accessories. This design allows the upper longitudinal beam to easily accommodate or replace additional components, such as energy absorbers or other functional modules, thereby enhancing the maintainability and adaptability of the vehicle.
