[0002] In the modern automobile industry, brackets are an important component used to connect automobile parts, and they have multiple functions of connection, bearing, vibration isolation and vibration prevention. A bracket can usually connect two to three or even more parts. However, since there are inevitably certain errors in the manufacturing process of parts, these errors often lead to the appearance of assembly gaps during the assembly process.

[0003] In order to solve this problem, the bracket connection structure in the existing technology usually needs to eliminate the assembly gap by adding adjustment gaskets. This process not only requires repeated disassembly and assembly of bolts, but also requires the selection of adjustment gaskets of appropriate specifications and quantity, which leads to low assembly efficiency, time-consuming and labor-intensive, and brings great inconvenience to the assembly work. At the same time, due to the different sizes of the gap space during connection and the impossibility of exhausting the specifications of the adjustment gaskets, in many cases the assembly gap cannot be completely eliminated, resulting in deformation of the bracket or component installation parts after assembly, affecting the assembly effect.

[0004] Therefore, the prior art has obvious shortcomings and deficiencies in the assembly of brackets, and there is an urgent need for a new bracket connection structure that can improve assembly efficiency, reduce labor intensity, ensure assembly effect, and eliminate assembly gaps conveniently and quickly.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] refer to Figure 1-3 An adjustable bracket connection structure is used for connecting a second component 6 with at least one first component 5, including a bracket body 3, the bracket body 3 includes a second connection part 34 and at least one first connection part 33, and there can be multiple first connection parts 33, so that multiple first components 5 and second components 6 can be connected together.

[0021] A connecting block 35 is provided between the first connecting portion 33 and the second connecting portion 34. The second connecting portion 34 can be coaxially arranged with the connecting block 35, and both ends of the second connecting portion 34 can protrude from both end surfaces of the connecting block 35. One end surface of the first connecting portion 33 can be flush with one end surface of the connecting block 35, and the other end surface of the first connecting portion 33 can protrude from the other end surface of the connecting block 35. The first connecting portion 33 is provided with a first mounting hole 31, and the second connecting portion 34 is provided with a second mounting hole 32. A second bolt 8 is penetrated through the second mounting hole 32. The second bolt 8 is threadedly engaged with the second component 6. A second gasket 7 is provided between the second bolt 8 and an end surface of the bracket body 3 away from the second component 6; the contact area between the second bolt 8 and the bracket body 3 can be increased, the pressure can be reduced, and loosening can be prevented.

[0022] A shaft sleeve 4 is coaxially arranged in the first mounting hole 31, and the shaft sleeve 4 and the first mounting hole 31 are transitionally matched. After the shaft sleeve 4 and the first mounting hole 31 are assembled, there is both a slight gap and a slight interference between the shaft sleeve 4 and the first mounting hole 31, thereby allowing a certain relative movement between the shaft sleeve 4 and the first mounting hole 31, while ensuring a certain connection strength, satisfying a certain flexibility, and having a certain stability, so that the bracket body 3 can slide along the axial direction of the shaft sleeve 4 under the action of an external force, thereby realizing the rapid adjustment of the assembly gap between the bracket body 3 and the first component 5 and the second component 6, without the need for re-disassembly and re-adjustment, reducing labor intensity, shortening assembly time, and completely eliminating the assembly gap between the bracket body 3 and the first component 5 and the second component 6, thereby improving the assembly effect and application scope.

[0023] The sleeve 4 includes a sliding portion 42 and a limiting portion 43. The sliding portion 42 is transitionally matched with the first mounting hole 31. The length of the sliding portion 42 is greater than the hole depth of the first mounting hole 31, which can ensure the sliding of the first connecting portion 33 on the sleeve 4. The limiting portion 43 is coaxially provided on the side of the sliding portion 42 close to the first component 5. The diameter of the limiting portion 43 is greater than the diameter of the sliding portion 42, which can limit the sliding amount of the first connecting portion 33 toward the first component 5, and at the same time, can increase the contact area between the first connecting portion 33 and the first component 5, thereby improving the fixing effect after assembly.

[0024] The sliding portion 42 and the limiting portion 43 are penetrated by a through hole 41, and a first bolt 1 is penetrated in the through hole 41. The first bolt 1 is threadedly engaged with the first component 5. A first gasket 2 is provided between the first bolt 1 and an end surface of the bracket body 3 away from the first component 5, which can increase the contact area between the first bolt 1 and the bracket body 3, reduce pressure and prevent loosening.

[0025] In some embodiments, the sliding amount of the bracket body 3 on the sleeve 4 must cover the gap adjustment amount when the bracket body 3 and the second component 6 are assembled, thereby completely eliminating the assembly gap between the bracket body 3 and the second component 6 and improving the assembly effect.

[0026] The specific working principle is as follows:

[0027] During assembly, the sliding portion 42 is first installed in transitional cooperation with the first mounting hole 31, and the limiting portion 43 is arranged between the first component 5 and the first connecting portion 33. The bracket body 3 and the shaft sleeve 4 are connected and fastened to the first component 5 using the first bolt 1 and the first washer 2; the bracket body 3 is connected to the second component 6 through the second mounting hole 32 using the second bolt 8 equipped with the second washer 7. When there is an assembly gap between the joint surfaces of the bracket body 3 and the second component 6, the second connecting portion 34 is pushed by the bolt tightening force of the second bolt 8 to move toward the second component 6, and the first connecting portion 33 is driven to slide on the shaft sleeve 4 through the connecting block 35 to complete the installation, thereby achieving the purpose of completely eliminating the assembly gap, and utilizing the adjustable performance of the bracket body 3 to quickly realize the connection and fastening of the first component 5 and the second component 6. At this point, the gap adjustment and quick fastening operation in the component connection are successfully completed.

[0028] In summary, the bracket connection structure of the present invention achieves stable connection and flexible adjustment between parts through its unique design, which not only improves assembly efficiency and quality, but also reduces working hours in the assembly process and ensures the assembly effect. It can be applied to various occasions requiring adjustable connection.
