[0029] See also Figure 1-Figure 3 , a passenger car chassis connecting piece, comprising:

[0030] The connector body 1 includes a main shell 11, a first load-bearing shell 12, and a second load-bearing shell 13. The side of the main shell 11 is provided with a side plate 15. The upper surfaces of the main shell 11 and the side plate 15 are respectively provided with a first through hole 16 and a second through hole 17;

[0031] The upper surface of the main shell 11 is provided with a first load-bearing shell 12 and a second load-bearing shell 13. The first load-bearing shell 12 is equidistantly distributed in an annular manner along the outer ring of the second load-bearing shell 13. The first load-bearing shell 12 and the second load-bearing shell 13 are both hemispherical blocks, and the lower surfaces of the hemispherical blocks are provided with hemispherical grooves. The top of the second load-bearing shell 13 is provided with a connecting pipe 14.

[0032] Based on the above, the setting of the first through hole 16 and the second through hole 17 enables the connector body 1 to be connected to the chassis by means of screws, and the setting of the side panel 15 can increase the strength of the connector body 1, and through the mutual cooperation between the first force-bearing shell 12 and the second force-bearing shell 13, the connector body 1 can be used in cooperation with the force-bearing part 2 and the internal part 3.

[0033] like Figure 1 and Figure 4 As shown, the force-bearing member 2 is arranged inside the connecting member body 1 and includes a force-releasing block 23, wherein:

[0034] The load-bearing member 2 includes a first block 21 and a second block 24. A first positioning groove 22 and a second positioning groove 25 are provided at one end of the first block 21 and the second block 24, respectively. A load-releasing block 23 is provided at the top of each of the first block 21 and the second block 24. The diameter of the load-releasing block 23 is equal to the inner diameter of the first load-bearing shell 12, and the load-releasing block 23 extends into the interior of the first load-bearing shell 12.

[0035] Based on the above, the setting of the first positioning groove 22 and the second positioning groove 25 makes the force-bearing member 2 applicable to the frame 4 with different cross-sections. The hemispherical unloading block 23 cooperates with the first force-bearing shell 12, so that when external force acts on the frame 4, the frame 4 transmits the external force to the unloading block 23 and the first force-bearing shell 12. At this time, the contact surface between the unloading block 23 and the first force-bearing shell 12 is an arc surface. Therefore, when the external force acts on the arc surface, there are component forces in different directions, thereby weakening the effect of the external force acting on the chassis and the connecting parts.

[0036] like Figure 1 and Figure 5 As shown, the internal component 3 is arranged inside the connector body 1 and includes a contact block 33 and a positioning hole 34, wherein the internal component 3 includes a first bottom block 31 and a second bottom block 35, and the bottom ends of the first bottom block 31 and the second bottom block 35 are respectively provided with a first limiting groove 32 and a second limiting groove 36, and the first limiting groove 32 and the second limiting groove 36 are both cross grooves, and the cross sections of the first limiting groove 32 and the second limiting groove 36 are different;

[0037] A contact block 33 is provided at the top of each of the first bottom block 31 and the second bottom block 35. The contact block 33 extends into the interior of the second load-bearing shell 13 and has a diameter equal to the inner diameter of the second load-bearing shell 13. A positioning hole 34 is provided at the top of the contact block 33. The positioning hole 34 communicates with the connecting pipe 14.

[0038] Based on the above, the first limiting groove 32 and the second limiting groove 36 cooperate with each other to fix the frame 4, and when the frame 4 is subjected to external force, it can be transmitted to the internal component 3, and under the action of the contact block 33 and the second force-bearing shell 13, the external force is dispersed to reduce the load caused by the external force as much as possible, and through the cooperation between the contact block 33 and the positioning hole 34, the interior of the internal component 3 can be set on the frame 4 set at ninety degrees to ensure that the connector has a wider range of applications.

[0039] In actual use of this embodiment, the connector body 1 can be fixed to the chassis by screws, and the frame body 4 is connected to the chassis by providing the internal parts 3 and the force-bearing parts 2;

[0040] The hemispherical unloading block 23 cooperates with the first load-bearing shell 12, so that when an external force acts on the frame 4, the frame 4 transmits the external force to the unloading block 23 and the first load-bearing shell 12. At this time, the contact surface between the unloading block 23 and the first load-bearing shell 12 is an arc surface, so when the external force acts on the arc surface, there are force components in different directions. Similarly, the contact block 33 and the second load-bearing shell 13 cooperate with each other, thereby reducing the effect of the external force acting on the chassis and the connecting parts.

[0041] The connecting piece replaces the welding machine to connect the frame 4 and the chassis to each other. The connection is carried out by screws and nuts, so it is easy to adjust and calibrate.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
