Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle manufacturing, and in particular relates to an adjustable CCB bracket. Background Art

[0002] The CCB bracket is the primary support for components such as the instrument panel, steering system, and air conditioning system. It consists of a crossbeam tube and multiple modular brackets welded or integrally molded onto the crossbeam tube. Assembly of the CCB bracket is accomplished by connecting the modular brackets to the vehicle body or other components.

[0003] Most of the existing CCB bracket structures are as follows Figure 1 As shown in the figure, the module bracket is a whole piece. Due to the inevitable tolerances in the production process, there will be a large gap between the end of the module bracket and the vehicle body or other components during assembly, making it impossible to install it directly in place. To solve this problem, a common solution is to use Figure 1 As shown, a tolerance nut is installed at the end of the module bracket to adjust the angle between the two and compensate for the tolerance gap between them. The specific structure of the tolerance nut can be referred to in existing patent CN116838680A, "Externally Actuated Omnidirectional Tolerance Adjuster." However, this method is difficult to manufacture. Furthermore, assembly using this tolerance nut is difficult, and after assembly, friction and vibration between the nut and the vehicle body or other component brackets can cause the nut to shift during use, making the connection between the CCB bracket and the vehicle body or other components unstable and affecting vehicle safety.

[0004] In order to solve the above problems, designing an adjustable CCB bracket is an important technical problem that those skilled in the art need to solve. Utility Model Content

[0005] The purpose of the present invention is to solve the above problems existing in the prior art and to provide an adjustable CCB bracket.

[0006] The purpose of this utility model is achieved through the following technical solutions:

[0007] An adjustable CCB bracket includes a crossbeam tube and a module bracket perpendicular to the crossbeam tube; the module bracket is formed by a first bracket and a second bracket connected together; the distal end of the first bracket is welded and fixed to the crossbeam tube; the proximal end of the first bracket and the distal end of the second bracket are connected by an adjustment bolt; the distal end of the second bracket is bolted to a mounting plate; the second bracket is displaced relative to the first bracket to adjust the distance between the end of the second bracket and the mounting plate.

[0008] Preferably, the cross-sections of the first bracket and the second bracket are U-shaped.

[0009] Preferably, two oppositely disposed end surfaces of the first bracket are formed with waist-shaped holes, and the length of the waist-shaped holes is 12±2 mm.

[0010] Preferably, a groove is further formed on the first bracket, the groove is located at the outer periphery of the waist-shaped hole, and the bottom of the groove contacts the upper surface of the second bracket.

[0011] Preferably, a support block is provided in the second bracket, and both ends of the support block protrude from two oppositely arranged end faces in the second support frame and contact the bottom of the groove; and a through hole is formed in the support block to facilitate the passage of the adjusting bolt; the through hole is displaced within the range limited by the waist-shaped hole.

[0012] Preferably, the adjusting bolt is an eccentric bolt or a common bolt.

[0013] Preferably, a through hole is formed on the proximal end surface of the second bracket, and a bolt passes through the mounting plate and the through hole in sequence to achieve assembly of the module bracket.

[0014] Preferably, the through hole corresponds to the center of the mounting plate.

[0015] The advantages of the technical solution of this utility model are mainly reflected in:

[0016] The module bracket is divided into two parts, and the total length of the module bracket is adjusted by adjusting the bolts to compensate for the different spacing tolerances between the module bracket and the vehicle body or other components, achieving fast and stable assembly. After assembly, the adjustment bolt position remains unchanged, enhancing the stability of the connection between the two and ensuring vehicle safety.

[0017] By designing a groove structure on the first bracket, the gap between the first bracket and the second bracket is reduced, and the contact area between the first bracket and the second bracket is increased, so that the connection between the two is tighter and more reliable;

[0018] The support block enhances the load-bearing and anti-deformation performance of the second bracket, effectively avoiding the second bracket from being deformed by force during the connection process. At the same time, the through hole limits the installation position of the adjusting bolt, thereby achieving fast and accurate installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The objectives, advantages, and features of the present invention are illustrated and explained through the following non-limiting description of preferred embodiments. These embodiments are merely typical examples of the application of the technical solutions of the present invention.

These terms are intended only for ease of description and simplification of the description, and are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of the scheme, with the operator as a reference, the direction closer to the operator is referred to as the proximal end, and the direction away from the operator is referred to as the distal end.

[0025] like Figure 2 As shown, the present invention discloses an adjustable CCB bracket, comprising a cross-beam tube 1 and a module bracket 2 perpendicular to the cross-beam tube 1. The cross-beam tube 1 is preferably rectangular in cross section, and its overall shape can be straight or curved. In the present invention, the overall shape is preferably designed to be curved to enhance manufacturing and compression resistance.

[0026] like Figures 2 to 3 As shown, the module bracket 2 is formed by a first bracket 21 and a second bracket 22 connected together. In the present invention, the cross-sections of the first bracket 21 and the second bracket 22 are preferably U-shaped to facilitate installation. The module bracket 2 is divided into two parts, and the overall length of the module bracket is adjusted using adjustment bolts 23 to compensate for tolerances between the module bracket and the vehicle body or other components, achieving fast and stable assembly. After assembly, the adjustment bolts remain in place, enhancing the stability of the connection and ensuring vehicle safety.

[0027] Specifically, the distal end of the first bracket 21 is welded to the crossbeam tube 1; the proximal end of the first bracket 21 is connected to the distal end of the second bracket 22 via an adjustment bolt 23. Waist-shaped holes 210 are formed on two opposing end surfaces of the first bracket 21, and these holes 210 are located near the second bracket 22. Furthermore, the length of the waist-shaped holes 210 is preferably 12 ± 2 mm, although other lengths are possible and can be adjusted based on specific usage requirements, which is not limited here.

[0028] Furthermore, a groove 211 is formed on the first bracket 21. The groove 211 is located on the outer periphery of the waist-shaped hole 210, and the bottom of the groove contacts the upper surface of the second bracket 22. By designing a groove structure on the first bracket 21, the gap between the first bracket 21 and the second bracket 22 is reduced, and the contact area between the first bracket 21 and the second bracket 22 is increased, making the connection between the two more tight and reliable.

[0029] like Figure 2 and Figure 3 As shown, a support block 221 is provided in the second bracket 22, and the support block 221 is located at the far end of the second bracket 22. Both ends of the support block 221 protrude from two oppositely disposed end surfaces of the second bracket 21 and contact the bottom of the groove 211. Figure 2 and Figure 4 As shown, the support block 221 is formed with a through hole 220 for the adjustment bolt 23 to pass through. The through hole 220 is movable within the range defined by the waist-shaped hole 210. The support block 221 enhances the load-bearing and deformation resistance of the second bracket 22, effectively preventing deformation of the second bracket 22 during connection. Furthermore, the through hole 220 defines the installation position of the adjustment bolt 23, enabling quick and accurate installation.

[0030] Furthermore, the adjusting bolt 23 can be an eccentric bolt or a conventional bolt. Conventional bolts are known structures and are not described in detail herein. An eccentric bolt is preferably used in the present invention, and includes the support block 221 and a connecting portion 223 extending through the through hole 220.

[0031] like Figures 2 to 4As shown, the distal end of the second bracket 22 is bolted to the mounting plate 3, and the outer periphery of the second bracket 22 is welded to the mounting plate 3. Specifically, a through-hole 222 is formed on the proximal end face of the second bracket 22, and the bolt passes through the mounting plate 3 and the through-hole 222 in sequence to realize the assembly of the module bracket 2. The through-hole 222 corresponds to the center of the mounting plate 3. It can be seen that the second bracket 22 is displaced relative to the first bracket 21 to adjust the distance between the end of the second bracket 22 and the mounting plate 3, so that the end of the second bracket 22 is stably abutted against the mounting plate 3, and the mounting plate 3 and the end of the second bracket 22 are connected by bolts to achieve a stable connection between the two, effectively avoiding the occurrence of adverse conditions such as displacement of the nut due to friction and shaking, and improving the safety of vehicle use.

[0032] There are many implementation methods for the present utility model, and all technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of the present utility model.
