Description

Technical Field

[0001] This utility model belongs to the field of automotive fender structure design technology, specifically relating to an automotive fender mounting structure. Background Technology

[0002] In the automotive manufacturing and assembly field, the fender, as a key component of the vehicle's exterior body panel and underbody protection, must not only meet the aerodynamic design requirements of the entire vehicle but also serve to shield the wheels from mud and water and cushion minor impacts. The stability, precision, and ease of assembly of its installation structure directly affect the vehicle's appearance consistency, driving safety, and subsequent maintenance efficiency. Currently, the mainstream automotive fender installation structure mostly adopts a fixed bracket and bolt connection method. That is, a metal fixed bracket is used to build a connecting bridge between the fender and the body, and bolts are then used to pass through the bracket and pre-drilled holes in the fender and body to achieve rigid fixation of the three.

[0003] However, during vehicle operation, road bumps and engine vibrations continuously act on the fender mounting area. Due to the lack of an effective anti-loosening buffer structure between the bolts and the bracket, the bolts are prone to loosening due to vibration after long-term use, causing the fender to shift, make abnormal noises, and in severe cases, even the edge of the fender may lift up, increasing safety hazards while driving. Utility Model Content

[0004] The purpose of this utility model is to provide an installation structure for automobile fenders in order to solve the above-mentioned problems. The elastic clamping block abuts against the threaded structure of the positioning bolt, and uses the force generated by the elastic deformation to tightly hold the end of the positioning bolt, effectively preventing the positioning bolt from loosening under the vibration environment of vehicle driving, and further enhancing the stability of the installation structure.

[0005] This utility model achieves the above objectives through the following technical solutions: An installation structure for an automobile fender includes a mounting bracket, a support base fixedly mounted at the bottom of the mounting bracket, a positioning mechanism fixedly mounted on the mounting bracket, the positioning mechanism including a fixing block and a pad, two fixing blocks fixedly connected inside the mounting bracket, threaded holes adapted to positioning bolts being opened in the fixing blocks, a pad fixedly mounted on the part of the mounting bracket near the fixing blocks, and a plurality of elastic clamping blocks fixedly connected to the end of the fixing blocks away from the pad.

[0006] Preferably, the positioning mechanism further includes a groove, the mounting bracket has a groove near the fixing block, and the fixing block is arranged in an "I" shape.

[0007] Preferably, the part of the mounting bracket that contacts the fixing block has an arc-shaped structure, and the pad has a semi-circular annular structure.

[0008] Preferably, a plurality of the elastic clamping blocks are arranged in a ring at equal intervals, and the ends of the elastic clamping blocks opposite to the fixed block are arranged with an inclined structure.

[0009] Preferably, the mounting bracket is provided with a limiting mechanism, which includes a socket and gaskets. The mounting bracket is provided with a socket, and a plurality of gaskets are fixedly connected to the part of the mounting bracket near the socket.

[0010] Preferably, the mounting bracket is arranged with an inclined structure near the insertion hole, and the plurality of gaskets are arranged in a ring at equal intervals.

[0011] Preferably, the mounting bracket has multiple shock-absorbing pads fixedly connected to the side wall in contact with the fender, and the support seat has an anti-slip pad fixedly connected to the side wall in contact with the vehicle body.

[0012] Preferably, both ends of the pad and the anti-slip pad are arranged with an arc surface structure, and the anti-slip pad is located on the side wall of the support seat away from the mounting bracket.

[0013] Compared with the prior art, the present invention has the following beneficial effects: (1) By adapting the shape and size of the mounting bracket to the fender, this utility model can provide a stable mounting base for the fender. The support can transmit the weight of the mounting bracket and the fender, as well as various forces generated during driving, to the vehicle body, ensuring the firmness of the fender installation. The fixing block is fixedly connected to the support and has threaded holes that are compatible with the positioning bolts, which can provide a precise positioning reference for the mounting bracket and the fender, ensuring the accuracy of the fender installation position.

[0014] (2) This utility model increases the contact area between the fixing block and the mounting bracket by using components such as a pad, so that the connection is more stable after the positioning bolt is tightened. It can effectively prevent the mounting bracket and fender from loosening or shifting during vehicle operation. The pad can avoid wear and scratches caused by direct contact between the fixing block and the mounting bracket. The elastic clamping block abuts against the thread structure of the positioning bolt and uses the force generated by elastic deformation to tightly hold the end of the positioning bolt, effectively preventing the positioning bolt from loosening in the vibration environment of vehicle operation, and further enhancing the stability of the installation structure.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 5 As shown, this utility model embodiment provides an installation structure for an automobile fender, including a mounting bracket 1. A support base 2 is fixedly installed at the bottom of the mounting bracket 1. The support base 2 serves as the bottom load-bearing component of the mounting bracket 1, which can evenly transfer the weight of the subsequent fender and the mounting bracket 1 to the vehicle body, avoiding localized stress concentration that could cause deformation of the body sheet metal. A positioning mechanism 3 is fixed on the mounting bracket 1. The positioning mechanism 3 includes a fixing block 301 and a pad 302. Two fixing blocks 301 are fixedly connected inside the mounting bracket 1. The fixing blocks 301 have threaded holes adapted to the positioning bolts 304. A pad 302 is fixed to the part of the mounting bracket 1 near the fixing blocks 301. The pad 302 can fill the small gap between the fixing blocks 301 and the mounting bracket 1, protecting the contact surface between the fixing blocks 301 and the mounting bracket 1 from wear. By selecting pads 302 of different thicknesses to match the component processing tolerances, the installation position of the fixing blocks 301 can be ensured to be accurate.

[0019] Please see Figures 1 to 5 As shown, a number of elastic clamping blocks 305 are fixedly connected to one end of the fixing block 301 away from the pad 302. The elastic clamping blocks 305 are distributed in a ring at equal intervals at one end of the fixing block 301 away from the pad 302. The beveled end design of the elastic clamping blocks 305 can reduce the resistance when the positioning bolt 304 is inserted, allowing the bolt to pass through smoothly and connect with the thread of the fixing block 301, which can improve the assembly efficiency. The mounting bracket 1 has a groove 303 near the fixing block 301. The fixing block 301 is set in an "I" shaped structure.

[0020] Please see Figures 1 to 5As shown, the part of the mounting bracket 1 that contacts the fixing block 301 has an arc-shaped structure, the pad 302 has a semi-circular ring structure, and several elastic clamping blocks 305 are arranged in a ring at equal intervals. After insertion, the elastic clamping blocks 305 deform elastically, and the inner side wall of the elastic clamping block 305 tightly abuts against the thread of the positioning bolt 304, forming a double fixing effect of elastic clamping and thread locking. This can effectively resist the loosening of the positioning bolt 304 caused by vehicle driving vibration and prevent the fender from shifting due to bolt loosening. The end of the elastic clamping block 305 away from the fixing block 301 has an inclined structure.

[0021] Please see Figures 1 to 5 As shown, the mounting bracket 1 is provided with a limiting mechanism 4, which includes a socket 401 and gaskets 402. The mounting bracket 1 is provided with a socket 401, and several gaskets 402 are fixedly connected to the part of the mounting bracket 1 near the socket 401. Several gaskets 402 are installed at equal intervals on the part of the mounting bracket 1 near the socket 401. The gaskets 402 distribute the pressure when the bolt is tightened, preventing the surface of the mounting bracket 1 from being damaged by the bolt head. At the same time, the elastic properties of the gaskets 402 can also help absorb vibration and ensure the long-term stability of the connection. The part of the mounting bracket 1 near the socket 401 is set with a sloping structure, and the several gaskets 402 are arranged in a ring at equal intervals.

[0022] Please see Figures 1 to 5 As shown, multiple shock-absorbing pads 5 are fixedly connected to the side wall of the mounting bracket 1 that contacts the fender, and an anti-slip pad 6 is fixedly connected to the side wall of the support seat 2 that connects to the vehicle body. The anti-slip pad 6 is fixed to the side wall of the support seat 2 away from the mounting bracket 1. Since the two ends of the anti-slip pad 6 are arc-shaped, it can not only avoid the sharp edges from scratching the surface of the vehicle body during installation, but also increase the contact friction between the support seat 2 and the vehicle body through the friction characteristics of its own material, preventing the support seat 2 from shifting due to vibration during vehicle operation; both ends of the pad 402 and the anti-slip pad 6 are set with arc-shaped structures, and the anti-slip pad 6 is located on the side wall of the support seat 2 away from the mounting bracket 1.

[0023] In use, this utility model firstly fixes the anti-slip mat 6 to the side wall of the support base 2 away from the mounting bracket 1. Because the anti-slip mat 6 has arc-shaped ends, it avoids sharp edges scratching the vehicle body surface during installation and increases the contact friction between the support base 2 and the vehicle body through its own material friction characteristics, preventing the support base 2 from shifting due to vibration during vehicle operation. Next, the support base 2 is aligned with the corresponding connection parts of the vehicle body to complete the initial fixing of the support base 2, ensuring that the support base 2 fits snugly against the vehicle body without looseness. As the bottom load-bearing component of the mounting bracket 1, the support base 2 can evenly transfer the weight of the subsequent fender and mounting bracket 1 to the vehicle body, avoiding localized stress concentration that could cause deformation of the body sheet metal. The entire mounting structure provides a stable underlying support, ensuring the stability of subsequent component assembly. Two fixing blocks 301 are fixed inside the mounting bracket 1. These fixing blocks 301, arranged in an "I" shape, match the curved surface of the mounting bracket 1, significantly increasing the contact area between them, dispersing the pressure transmitted by the mounting bracket 1, and preventing the fixing blocks 301 from detaching from the mounting bracket 1 due to excessive localized stress. A semi-circular annular pad 302 is fixed to the mounting bracket 1 near the fixing blocks 301. The pad 302 fills the small gap between the fixing blocks 301 and the mounting bracket 1, protecting the contact surfaces of the fixing blocks 301 and the mounting bracket 1 from wear, and allowing for adjustments by selecting pads 302 of different thicknesses. The machining tolerances of the components ensure the precise installation position of the fixing block 301. The mounting bracket 1 has a groove 303 near the fixing block 301, providing a clear pre-positioning reference for the fixing block 301 and preventing lateral displacement within the mounting bracket 1. This lays the foundation for the precise installation of the subsequent positioning bolt 304 and reduces deviations during bolt installation. Several elastic clamping blocks 305 are evenly distributed in a ring at one end of the fixing block 301 away from the pad 302. The beveled end design of the elastic clamping blocks 305 reduces the resistance when the positioning bolt 304 is inserted, allowing the bolt to pass smoothly and connect with the thread of the fixing block 301, improving assembly efficiency. After insertion, the elastic clamping blocks 305 deform elastically, and their inner walls tightly contact the threads of the positioning bolt 304, forming a dual fixing effect of elastic clamping and thread locking, effectively resisting the vibration of the positioning bolt 304 caused by vehicle movement. To prevent the fender from shifting due to loose bolts, several washers 402 are evenly installed on the mounting bracket 1 near the insertion hole 401. The washers 402 distribute the pressure when the bolts are tightened, preventing the surface of the mounting bracket 1 from being damaged by the bolt heads. At the same time, the elastic properties of the washers 402 can also help absorb vibration and ensure the long-term stability of the connection. Multiple shock-absorbing pads 5 are fixed to the side wall of the mounting bracket 1 that contacts the fender. The shock-absorbing pads 5 can absorb the vibration and friction between the fender and the mounting bracket 1 during vehicle operation, avoiding wear and noise caused by direct contact between metal parts and improving driving comfort. At the same time, the shock-absorbing pads 5 can buffer the impact force transmitted to the fender by road bumps, reduce the cracking of weld points or edge deformation of the fender due to long-term vibration, and extend the service life of the fender.
