[0029] One of the preferred embodiments of this application is as follows: Figures 1 to 9As shown, a high-strength front crossbeam of a car roof comprises a crossbeam body 1 and a plurality of mounting grooves 11 provided on the side of the crossbeam body 1; an energy absorbing component 2 is also provided on the crossbeam body 1, and the energy absorbing component 2 and the crossbeam body 1 are matched through a locking structure 12; and then when the crossbeam body 1 is subjected to energy absorption and shock reduction, the energy absorbing component 2 can be set in the mounting groove 11 for installation, and then the locking structure 12 is driven so that the energy absorbing component 2 can be fitted and locked with both sides of the crossbeam body 1, so that the energy absorbing component 2 can be firmly fitted with both sides of the crossbeam body 1, so that the energy absorbing component 2 can fix the crossbeam body 1, and the energy absorbing component 2 can make the crossbeam body 1 have higher strength while the energy absorbing component 2 can also reduce the shock of the crossbeam body 1, thereby improving the energy absorption effect and reducing the vibration of the crossbeam body 1. It has a simple structure, is easy to install, has good economic effect and is highly practical.

[0030] In this embodiment, Figures 1 to 3 As shown, it can be understood that the locking structure 12 includes a threaded column 121 and a threaded sleeve 122; the threaded column 121 and the threaded sleeve 122 cooperate with each other, and then extend into the installation groove 11 through the threaded column 121. Through the cooperation of the threaded sleeve 122 and the threaded column 121, the energy absorption component 2 can better fit the two sides of the beam body 1, so that the energy absorption component 2 can not only fix the beam body 1 to enhance the strength, but also absorb the vibration generated by the beam body 1, thereby reducing the vibration of the beam body 1 and improving the driving environment and comfort of the personnel.

[0031] In this embodiment, Figures 1 to 3 As shown, it can be understood that the energy absorbing assembly 2 includes at least one fixing plate 21 and an energy absorbing plate 22; at least one fixing plate 21 is arranged on the side of the threaded column 121, and the energy absorbing plate 22 is arranged on the side of the threaded sleeve 122, and at least one fixing plate 21 cooperates with the energy absorbing plate 22; then, when the crossbeam body 1 is subjected to energy absorption and shock absorption, the threaded column 121 can be inserted into the mounting groove 11, and then the threaded sleeve 122 can be arranged on the threaded column 121, and then the threaded sleeve 122 can be rotated to make the threaded column 121 move up, and the threaded column 1 The upward movement of 21 can drive the fixed plate 21 to move upward to fit and squeeze with one side of the beam body 1. After the threaded column 121 moves upward, the threaded sleeve 122 can move downward. The downward movement of the threaded sleeve 122 can drive the energy absorbing plate 22 to fit with the other side of the beam body 1, thereby making the fixed plate 21 and the energy absorbing plate 22 fit with both sides of the beam body 1. The beam body 1 can be fixed by the fixed plate 21 and the energy absorbing plate 22, thereby improving the strength of the beam body 1 and reducing the vibration of the beam body 1, thereby improving the energy absorption effect. The structure is simple and practical.

[0032] In this embodiment, Figures 4 to 9As shown, it can be understood that the configuration of the fixing plate 21 includes but is not limited to the following four configurations.

[0033] Setting method 1: Figure 5 and Figure 6 As shown, the fixing plate 21 is circular and arranged on the side of the threaded column 121. The fixing plate 21 is made of high-strength rubber material. When the threaded column 121 is driven to move upward, the side of the fixing plate 21 can be fitted and fixed to the side of the beam body 1 without scratching the side of the beam body 1. At the same time, it can provide stable support for the beam body 1, so as to better make the beam body 1 have a certain strength, and can also absorb energy of the beam body 1 and reduce the vibration of the beam body 1.

[0034] Setting method 2: Figure 4 As shown, two fixing plates 21 are provided, and the two fixing plates 21 are arranged obliquely on both sides of the threaded column 121. The two fixing plates 21 are made of high-toughness plastic material. During installation, the threaded column 121 drives the two inclined fixing plates 21 to fit with the side of the beam body 1. The two fixing plates 21 can provide stable support for the beam body 1, and can also absorb energy of the beam body 1 to reduce the vibration of the beam body 1. The structure is simple and practical.

[0035] Setting method three: Figure 7 and Figure 8 As shown, two fixing plates 21 are provided, and the two fixing plates 21 are horizontally arranged on both sides of the threaded column 121. The two fixing plates 21 are made of high-strength rubber material, and then during installation, the threaded column 121 drives the two fixing plates 21 to fit with the side of the beam body 1, and thus will not squeeze, deform or scratch the side of the beam body 1. At the same time, it can provide stable support for the beam body 1, so as to better make the beam body 1 have a certain strength, and can also absorb energy of the beam body 1 and reduce the vibration of the beam body 1. The structure is simple and practical.

[0036] Setting method 4: Figure 9 As shown, there are two fixing plates 21, and the two fixing plates 21 are hemispherical and arranged on both sides of the threaded column 121. The two hemispherical fixing plates 21 are made of high-strength rubber material. During installation, the threaded column 121 drives the arc sections of the two hemispherical fixing plates 21 to fit with the side of the beam body 1, thereby providing support for the beam body 1 while absorbing energy of the beam body 1 and reducing the deformation of the beam body 1, thereby better protecting the beam body 1. At the same time, it can also reduce the vibration of the beam body 1, thereby improving the energy absorption effect and having strong practicality.

[0037] It is understandable that the four configurations of the fixing plate 21 mentioned above all meet the requirements of this application, and those skilled in the art can select a suitable configuration according to actual conditions.

[0038] In this embodiment, Figures 1 to 3 As shown, it can be understood that the configuration of the energy absorbing plate 22 includes but is not limited to the following two configurations.

[0039] Setting method 1: Figure 1 and Figure 2 As shown, the energy absorbing plate 22 is rectangular and is arranged on the side of the threaded sleeve 122. During installation, the threaded column 121 drives the fixing plate 21 to move up and be fixed to one side of the beam body 1. At this time, the threaded sleeve 122 can drive the energy absorbing plate 22 to move down and be fixed to the other side of the beam body 1, so that the energy absorbing plate 22 is parallel or perpendicular to the length direction of the beam body 1, so that the energy absorbing plate 22 can better fix and absorb energy of the beam body 1, thereby improving the strength and energy absorption effect of the beam body 1, and is highly practical.

[0040] Setting method 2: Figure 1 and Figure 3 As shown, the energy absorbing plate 22 is arranged in a cross shape. During installation, the threaded column 121 drives the fixing plate 21 to move up and be fixed to one side of the beam body 1. At this time, the threaded sleeve 122 can drive the energy absorbing plate 22 to move down and be fixed to the other side of the beam body 1, so that the energy absorbing plate 22 can better fix and absorb energy of the beam body 1, thereby improving the strength and energy absorption effect of the beam body 1, and is highly practical.

[0041] It can be understood that both settings of the above-mentioned energy-absorbing plate 22 meet the requirements of this application. Technicians in this field can choose according to actual conditions and use them in conjunction with the above-mentioned fixed plate 21 to better absorb energy and improve the strength of the beam body 1, while also saving costs, having a simple structure and strong practicality.
