Description

Technical Field

[0001] This application relates to the field of automotive parts technology, specifically a lightweight car body and anti-collision structure. Background Technology

[0002] Collision protection structures are an important component of vehicle safety. Their main function is to absorb and disperse collision energy when a vehicle collides, protecting the integrity of the passenger compartment and the safety of the occupants.

[0003] The anti-collision structure is connected to the vehicle body beam at designated locations using bolts. Pre-installed bolts on both the anti-collision beam and the body beam are passed through, and then nuts are tightened. The bolts primarily bear axial tensile force. When the nuts are tightened, the preload generated by the bolts ensures a tight fit between the anti-collision beam and the vehicle frame, relying on friction to resist external forces during a vehicle collision. This connection method facilitates installation and disassembly and is commonly used for installing anti-collision beams in automotive repair or modification scenarios.

[0004] When driving on mountain roads, frequent uphill and downhill sections and potholes can cause significant vibrations to the vehicle body. Compared to driving on flat roads, the frequency and amplitude of alternating stress on the bolts will increase, making it easier for the anti-collision structure to loosen at the bolt installation points. Utility Model Content

[0005] The purpose of this application is to provide a lightweight vehicle body and anti-collision structure to solve the problem mentioned in the background art that the frequency and amplitude of alternating stress on bolts will increase, making it easier for the anti-collision structure to loosen at the bolt installation points.

[0006] To achieve the above objectives, this application provides the following technical solution: The present invention provides an anti-collision structure, comprising: an anti-collision beam body, an anti-loosening component, and a positioning component. The anti-collision beam body has mounting holes pre-drilled at both ends. The anti-loosening component is disposed on both sides of the outer wall of the anti-collision beam body. The anti-loosening component includes U-shaped blocks welded to both sides of the outer wall of the anti-collision beam body, with two sets of circular holes on the U-shaped blocks, a fixing block welded to one side of the outer wall of the U-shaped blocks, a connecting shaft welded to the outer wall of the fixing block, and an M-shaped block rotatably connected to the connecting shaft. An insertion interface is provided on the outer wall of the M-shaped block. The positioning component is disposed inside the circular holes of the U-shaped blocks.

[0007] By adopting the above technical solution, it is possible to prevent the nuts of the fixing bolts from loosening after the main body of the anti-collision beam is installed by fixing bolts.

[0008] Preferably, the positioning component includes two sets of plug rods slidably connected in the two sets of circular holes of the U-shaped block, a connecting plate welded to one end of the two sets of plug rods, and a No. 1 spring sleeved on the two sets of plug rods. The other end of the plug rod is adapted to the insertion interface diameter of the M-shaped block.

[0009] By adopting the above technical solution, the plug rod can be positioned by inserting it into the plug hole of the M-shaped block.

[0010] Preferably, the positioning component further includes a rectangular block welded to the inner wall of the U-shaped block and an L-shaped block slidably connected to the rectangular block.

[0011] By adopting the above technical solution, the L-shaped block can achieve stable sliding displacement on the rectangular block.

[0012] Preferably, the positioning component further includes a first trapezoidal tooth block welded to the outer wall of the L-shaped block and a second trapezoidal tooth block disposed inside the U-shaped block. The second trapezoidal tooth block is integrally formed with a connecting rod. The second trapezoidal tooth block is slidably disposed inside the U-shaped block through the connecting rod, and a lever is welded to the other end of the connecting rod of the second trapezoidal tooth block.

[0013] By adopting the above technical solution, the second trapezoidal toothed block on the connecting rod can be moved by the hand-held lever.

[0014] Preferably, the positioning component further includes a second spring sleeved on the connecting rod of the second trapezoidal toothed block.

[0015] By adopting the above technical solution, the second trapezoidal tooth block can be moved by the compression and pushing of the second spring.

[0016] In another aspect, this utility model provides a lightweight vehicle body, including a collision protection structure as described above. The lightweight vehicle body further includes: a body beam body and fixing bolts. The body beam body can be made of high-strength steel, aluminum alloy, and magnesium alloy lightweight materials to effectively reduce the weight of the vehicle body. The fixing bolts are welded to the outer wall of the body beam body and consist of a screw and a nut connected by threads. The collision protection beam body is inserted into the screw of the fixing bolt through a mounting hole.

[0017] By adopting the above technical solution, the main body of the anti-collision beam can be fixed to the main body of the vehicle body beam by fixing bolts.

[0018] In summary, this application includes at least one of the following beneficial effects:

[0019] (1) By setting an anti-loosening component, after the main body of the anti-collision beam is connected by a fixing bolt, in order to avoid the vibration caused by long-term driving, the nut of the fixing bolt can be limited by the anti-loosening component, which can prevent the nut of the fixing bolt from rotating and loosening under the influence of vibration. The function is to stably fix the main body of the anti-collision beam to the main body of the vehicle body beam.

[0020] (2) By setting up a positioning component and an anti-loosening component, the anti-loosening component can limit the fixing bolt by changing the angle, and when the anti-loosening component is performing its own function, it can prevent the anti-loosening component from continuing to change the angle, so that the anti-loosening component can continuously and stably position the anti-loosening component.

[0027] The following is in conjunction with the appendix Figure 1-4 The embodiments of this application will be described in further detail.

[0030] The main body of the anti-collision beam 1 has pre-drilled mounting holes at both ends.

[0031] The anti-loosening component 2 is installed on both sides of the outer wall of the anti-collision beam body 1. The anti-loosening component 2 includes U-shaped blocks 201 welded to both sides of the outer wall of the anti-collision beam body 1. Two sets of round holes are opened on the U-shaped blocks 201. A fixing block 202 is welded to one side of the outer wall of the U-shaped blocks 201. A connecting shaft 203 is welded to the outer wall of the fixing block 202 and an M-shaped block 204 is rotatably connected to the connecting shaft 203. An insertion interface is opened on the outer wall of the M-shaped block 204.

[0032] The positioning component 3 is set inside the circular hole of the U-shaped block 201. The positioning component 3 includes two sets of plug rods 301 that are slidably connected in the two sets of circular holes of the U-shaped block 201, a connecting plate 302 welded to one end of the two sets of plug rods 301, and a first spring 303 sleeved on the two sets of plug rods 301. The other end of the plug rod 301 is adapted to the diameter of the plug interface of the M-shaped block 204.

[0033] The positioning component 3 also includes a rectangular block 304 welded to the inner wall of the U-shaped block 201 and an L-shaped block 305 slidably connected to the rectangular block 304, a first trapezoidal toothed block 306 welded to the outer wall of the L-shaped block 305 and a second trapezoidal toothed block 307 disposed inside the U-shaped block 201. The second trapezoidal toothed block 307 is integrally formed with a connecting rod. The second trapezoidal toothed block 307 is slidably disposed inside the U-shaped block 201 through the connecting rod. A lever 308 is welded to the other end of the connecting rod of the second trapezoidal toothed block 307, and a second spring 309 is sleeved on the connecting rod of the second trapezoidal toothed block 307.

[0034] Example 2

[0035] Please see Figures 1-2 This embodiment provides a technical solution: a lightweight car body, including: a car body beam body 4 and fixing bolts 5;

[0036] The lightweight body also includes: body beam body 4 and fixing bolts 5. The body beam body 4 can be made of high-strength steel, aluminum alloy and magnesium alloy lightweight materials to effectively reduce the weight of the body. The fixing bolts 5 are welded to the outer wall of the body beam body 4. The fixing bolts 5 are composed of a screw and a nut connected by threads. The anti-collision beam body 1 is inserted into the screw of the fixing bolts 5 through the mounting hole.

[0037] The implementation principle of the lightweight car body and anti-collision structure of this application is as follows:

[0038] First, loosen the nut on the fixing bolt 5 of the body beam 4 from the threaded rod. Then, align the mounting hole of the anti-collision beam 1 with the threaded rod of the fixing bolt 5 and insert it. By turning the nut on the threaded rod, the body beam 4 and the anti-collision beam 1 are connected by the fixing bolt 5. The anti-loosening component 2 can prevent the nut of the fixing bolt 5 from loosening on the threaded rod, and the positioning component 3 can prevent the anti-loosening component 2 from rotating again after rotating to the specified angle.

[0039] Secondly, because a connecting shaft 203 is welded to the fixing block 202 of the U-shaped block 201, the M-shaped block 204 on the connecting shaft 203 can change its angle. When the M-shaped block 204 rotates, it limits the nut of the fixing bolt 5, thus preventing the nut of the fixing bolt 5 from loosening during vibration.

[0040] Finally, when it is necessary to position the angle of the M-shaped block 204 after the angle change, the second trapezoidal toothed block 307 is moved vertically upward by holding the lever 308. At this time, the second trapezoidal toothed block 307 is no longer squeezed and pushed by the second spring 309. The second trapezoidal toothed block 307 is no longer engaged with the first trapezoidal toothed block 306 on the L-shaped block 305. At this time, the first spring 303 will use its own elastic force to pull the connecting plate 302 and the plug rod 301 together to move, so that the plug rod 301 can be inserted into the plug hole of the M-shaped block 204, thereby realizing the positioning of the M-shaped block 204 after the angle change. After the connecting plate 302 moves, the L-shaped block 305 can be slid back to its original position on the rectangular block 304 by the displacement of the connecting plate 302.

[0041] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
