[0015] Technical effects and advantages of the present invention:

[0016] 1. The present invention adjusts the positions of the two moving frames by rotating the rotating rod and using the movable block and the two first rotating plates. The two clamps are driven by the moving frames to gradually cooperate with the inclined surface of the first card slot to make the bumper gradually approach the first bracket until the clamps and the first bracket are completely corresponding and limited, completing the rapid installation of the bumper. The rotating rod is rotated in the opposite direction, and the two moving frames slide inside the slide slot under the push of the first rotating plate. The two moving frames gradually move away from each other during the sliding process. At this time, the two moving frames drive the clamps to gradually separate from the first card slot, making it convenient to remove the bumper from the first bracket, ensuring the rapid disassembly effect of the bumper.

[0017] 2. When the external impact force acts on the bumper of the present invention, the bumper facilitates the clamp to push the screw to move. When the screw slides on the surface of the square and round rod by using the square and round groove, the rear end of the screw squeezes the first spring inside the second clamping groove. The elastic force of the first spring can reduce the impact force of the bumper on the first bracket, and at the same time avoid the bumper from directly impacting the first bracket, thereby reducing the impact damage between the bumper and the first bracket.

[0018] When the cam is in the state of being moved, the two second rotating plates are used to rotate, and the two first sliding blocks are pulled by the middle frame to move in the limited groove. At this time, the first sliding block uses the middle rod to slide in the limited groove. At this time, the first sliding block cooperates with the second sliding block to squeeze the second spring, thereby increasing the elastic force of the second spring between the first sliding block and the second sliding block. After loosening the limiting nut, the second spring elastic force between the first sliding block and the second sliding block and the second spring elastic force outside the first sliding block make the second sliding block fit tightly with the front side of the limited groove. The second sliding block is limited by the spiral of the movable frame and the rotating rod, so that the first sliding block is limited by the middle frame and the two second rotating plates, thereby improving the buffering effect of the entire buffer device.

[0019] 4. The present invention transmits the force acting on the bumper to the fixed rod through the first bracket. When the external impact force acts on the movable frame through the fixed rod, the movable frame drives the connecting frame to move by using the clamping frame, and the connecting frame uses the second groove to make the second slider move inside the limited groove. When the clamping frame drives the connecting frame to move, the second slider uses the connecting frame to pull the clamping frame to slide inside the groove. At this time, the two clamping frames gradually move away from each other during the movement; the movable frame drives the middle frame to move by using the rotating rod under the action of the impact force, and the middle frame uses the two second rotating plates to make the two first sliders move inside the limited groove. At this time, the first slider and the second slider squeeze the second spring during the sliding process, and the elastic force of the second spring is used to absorb the impact force acting on the movable frame, so as to avoid the external impact force acting on the vehicle body, thereby reducing the damage to the vehicle body.

[0020] Other features and advantages of the present invention will be described in the following description, and partly become obvious from the description, or be understood by implementing the present invention.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] The present invention provides a car bumper support structure that is easy to disassemble, such as Figure 1-2As shown, it includes a first bracket 1 and a second bracket 2, the first bracket 1 and the second bracket 2 are separately arranged, a bumper 3 is sleeved on the surface of the first bracket 1, a fixing rod 4 is arranged at the top and bottom of the center of the rear side of the first bracket 1, one end of the fixing rod 4 is fixedly connected to the rear side of the first bracket 1, a movable frame 5 is arranged on the rear side of the second bracket 2, the other end of the fixing rod 4 penetrates the second bracket 2 and is fixedly connected to the front side of the movable frame 5, both sides of the movable frame 5 are provided with a buffer device corresponding to the first bracket 1, and the inner side end of the buffer device is slidably connected to the movable frame 5, the first bracket 1 is connected to the second bracket 2 correspondingly by using the fixing rod 4 and the buffer device, a rotating rod 6 is arranged between the two fixing rods 4, the rotating rod 6 penetrates the center of the second bracket 2, and one end of the rotating rod 6 is movably connected to the clamping device, the rotating rod 6 spirally penetrates the center of the movable frame 5, and the other end of the rotating rod 6 is movably connected to the buffer device, the clamping device is installed on the first bracket 1, and the front side end of the clamping device is sleeved with a clamp 7, and the rear side of the bumper 3 is provided with a first card groove 8 corresponding to the clamp 7. The rear side surface of the bumper 3 is correspondingly sleeved on the first bracket 1. When the two clamps 7 are close to each other, the clamping device installed on the first bracket 1 uses the clamp 7 to clamp the first slot 8 of the bumper 3 to ensure the tightness of the connection between the bumper 3 and the first bracket 1. When the two clamps 7 are separated from each other, the clamp 7 of the clamping device and the first slot 8 are separated, which makes it convenient and quick to remove the bumper 3 from the first bracket 1, thereby improving the convenience of disassembly of the bumper 3 in the entire bumper bracket.

[0029] When an external impact force acts on the bumper 3, the force acting on the bumper 3 is transmitted to the fixing rod 4 through the first bracket 1, and then directly transmitted to the buffer devices on both sides of the movable frame 5. The buffer devices absorb the force acting on the movable frame 5, avoiding the external impact force from acting on the vehicle body, thereby reducing damage to the vehicle body.

[0030] exist Figure 1 and Figure 3In the embodiment, the rear side surfaces of both ends of the first slot 8 are provided with inclined surfaces 801, and the inclined direction of the inclined surfaces 801 gradually approaches the center of the rear side surface of the bumper 3 from the end of the first slot 8 to the center of the first slot 8, and the distance between the outer end of the inclined surface 801 and the rear side surface of the bumper 3 is greater than the distance between the inner end of the inclined surface 801 and the rear side surface of the bumper 3, and the clamping device uses the clamp 7 to correspond to the inclined surface 801 of the first slot 8. When the two clamps 7 approach each other, the clamp 7 moves from the end of the first slot 8 to the center of the first slot 8, and the rear side surface of the clamp 7 contacts the inclined surface 801 of the first slot 8, and the rear side surface of the clamp 7 slides on the inclined surface 801 of the first slot 8. Due to the inclined setting of the inclined surface 801, the sliding cooperation between the clamp 7 and the inclined surface 801 makes the inner side surface of the bumper 3 gradually approach the first bracket 1, until the clamp 7 is completely buckled with the first slot 8, which can improve the stability of the connection between the first bracket 1 and the bumper 3.

[0031] exist Figure 1 and Figure 2 In the embodiment, the clamping device includes a movable block 9, a rotating groove 10 for rotating with the end of the rotating rod 6 is provided at the center of the rear side surface of the movable block 9, movable frames 11 are provided on both sides of the movable block 9, and first rotating plates 12 corresponding to the two movable frames 11 are provided on both sides of the movable block 9, a sliding groove 13 for slidingly cooperating with the movable frame 11 is provided at the center of the first bracket 1, and the mobile frame 11 passes through the sliding groove 13 of the first bracket 1, and limiting rods 14 are provided at the top and bottom of the sliding groove 13, and fixed blocks 15 for limiting and cooperating with the limiting rod 14 are provided at the top and bottom of the movable frame 11, and the limiting rod 14 passes through the fixed block 15. The two moving frames 11 are respectively located on both sides of the slide groove 13. The two moving frames 11 use the first rotating plate 12 to limit the position of the movable block 9. When the two moving frames 11 need to slide on the inner side of the slide groove 13, the rotating rod 6 is rotated. The spiral effect of the rotating rod 6 and the movable frame 5 makes the rotating rod 6 move inside the second bracket 2, and the end of the rotating rod 6 drives the movable block 9 to gradually approach the second bracket 2 during the movement. The movable block 9 pulls the inner end of the first rotating plate 12 to move, and the first rotating plate 12 rotates as a whole. The movable block 9 uses the first rotating plate 12 to rotate to make the two moving frames 11 slide on the inner side of the slide groove 13, and the clamps 7 connected to the front ends of the two moving frames 11 can move synchronously with the moving frames 11.

[0032] When the moving frame 11 slides inside the slide groove 13, the fixed blocks 15 at the top and bottom of the moving frame 11 move on the limiting rods 14 at the top and bottom of the slide groove 13 respectively, and the two limiting rods 14 are used to improve the sliding stability of the moving frame 11 inside the slide groove 13, while also preventing the moving frame 11 from rotating inside the slide groove 13.

[0033] exist Figure 2 and Figure 4In the embodiment, a screw rod 16 is movably connected at the center of the front side of the mobile frame 11, a second slot 17 is provided inside the mobile frame 11 to match the rear side of the screw rod 16, and the rear side of the screw rod 16 is fixedly connected to the inner side wall of the second slot 17 by using a first spring 18, a square rod 19 is fixedly connected at the center of the second slot 17, a square groove 20 is provided at the center of the screw rod 16 to match the square rod 19, and the screw rod 16 is slidably matched with the square rod 19 by using the square groove 20, and the rear side of the chuck 7 is spirally sleeved on the front side of the screw rod 16. The rear side of the chuck 7 is aligned with the screw rod 16, and the chuck 7 is rotated. Since the square rod 19 limits the screw rod 16 by using the square groove 20, the chuck 7 is gradually sleeved on the surface of the screw rod 16 during the rotation process, until the two chucks 7 are arranged relatively, and the two chucks 7 can be tightly sleeved on the surface of the screw rod 16. When the moving frame 11 clamps the bumper 3 by the clamp 7 at the end of the screw 16, the front side of the clamp 7 contacts the rear side of the bumper 3, and the top and bottom of the bumper 3 can be wrapped on the surface of the first bracket 1. The two clamps 7 are gradually inserted into the first slot 8 under the drive of the moving frame 11. Under the cooperation of the clamp 7 and the inclined surface 801 of the first slot 8, the bumper 3 gradually approaches the first bracket 1 until the clamp 7 and the first bracket 1 are completely corresponding to each other. When the external impact force acts on the bumper 3, the bumper 3 facilitates the clamp 7 to push the screw 16 to move. When the screw 16 slides on the surface of the square rod 19 by the square groove 20, the rear end of the screw 16 squeezes the first spring 18 in the second slot 17. The elastic force of the first spring 18 can reduce the impact force of the bumper 3 on the first bracket 1, and avoid the bumper 3 directly impacting the first bracket 1, thereby reducing the impact damage between the bumper 3 and the first bracket 1.

[0034] exist Figure 1 and Figure 2 In the embodiment, the spiral sleeve on the surface of the fixing rod 4 has a limiting nut 21, and the limiting nut 21 limits the sliding position of the fixing rod 4 inside the second bracket 2, and the rear side of the limiting nut 21 is in corresponding contact with the front side of the second bracket 2. The rear side of the limiting nut 21 fits with the front side of the second bracket 2, and the limiting nut 21 is rotated, and the spiral cooperation between the limiting nut 21 and the fixing rod 4 causes the fixing rod 4 to move, and the fixing rod 4 pulls the movable frame 5 to move until the movable frame 5 cannot move, which is convenient for limiting the relative distance between the first bracket 1 and the second bracket 2. When the bumper 3 is installed on the first bracket 1, due to the limitation of the fixing rod 4 by the limiting nut 21, the first bracket 1 cannot slide on the second bracket 2 using the fixing rod 4. When the rotating rod 6 is rotated, the movable block 9 and the two first rotating plates 12 are used to adjust the positions of the two movable frames 11, which is convenient for real-time adjustment of the position of the chuck 7, thereby ensuring the stability of the bumper 3 installation.

[0035] exist Figure 2In the embodiment, the buffer device includes an intermediate frame 22, the end of the rotating rod 6 is located inside the intermediate frame 22, and the end of the rotating rod 6 is rotatably connected to the intermediate frame 22, the first grooves 23 are provided at both ends of the rear side surface of the second frame 2, the limiting grooves 24 are provided at both sides inside the second frame 2, and the limiting grooves 24 are connected to the outside through the first grooves 23, and the first slider 25 is provided at the rear side of the limiting groove 24, and the two ends of the intermediate frame 22 are respectively rotatably connected to the two first sliders 25 by using the second rotating plate 26, and the first slider 25 is slidably matched with the limiting groove 24 by using the first groove 23. An intermediate rod 27 is provided inside the limiting groove 24, and a second slider 28 is provided at the front side of the inner side of the limiting groove 24, and the intermediate rod 27 passes through the first slider 25 and the second slider 28 respectively, and a second spring 29 is sleeved on the surface of the intermediate rod 27, one end of the second spring 29 is fixedly connected to the rear side surface of the second slider 28, and the other end of the second spring 29 is fixedly connected to the rear end surface of the limiting groove 24, and the first slider 25 and the second spring 29 are provided as one body. At this time, the elastic force between the first slider 25 and the second slider 28 can be adjusted, and the rotating rod 6 is rotated. The spiral cooperation of the rotating rod 6 and the movable frame 5 drives the movable block 9 to move, and can also drive the middle frame 22 to move. At this time, the middle frame 22 gradually moves away from the second bracket 2 during the movement of the rotating rod 6, and the middle frame 22 drives the inner ends of the two second rotating plates 26 to move. At this time, the two second rotating plates 26 rotate, and the middle frame 22 uses the two second rotating plates 26 to pull the two first sliders 25 to move inside the limiting groove 24. At this time, the first slider 25 uses the middle rod 27 to slide inside the limiting groove 24. At this time, the first slider 25 and the second slider 28 cooperate to squeeze the second spring 29, thereby increasing the elastic force of the second spring 29 between the first slider 25 and the second slider 28. After loosening the limiting nut 21, the elastic force of the second spring 29 between the first slider 25 and the second slider 28 and the elastic force of the second spring 29 outside the first slider 25 make the second slider 28 fit tightly with the front side of the limiting groove 24. The second slider 28 is limited by the spiral of the movable frame 5 and the rotating rod 6, so that the first slider 25 is limited by the intermediate frame 22 and the two second rotating plates 26, thereby improving the buffering effect of the entire buffer device.

[0036] exist Figure 2In the embodiment, the second bracket 2 is provided with a second groove 30 on both sides of the rear side, and the second groove 30 is provided corresponding to the second slider 28. The movable bracket 5 is provided with a connecting bracket 31 on both sides of the front side, and one end of the connecting bracket 31 is fixedly connected to the second slider 28 through the second groove 30, and the other end of the connecting bracket 31 is connected to a clamping bracket 32, and the clamping bracket 32 ​​drives the second slider 28 to slide inside the second groove 30 by using the connecting bracket 31. The ends of the movable bracket 5 do not contact the rear side of the second bracket 2, and the ends of the movable bracket 5 are provided with grooves 33 corresponding to the clamping bracket 32, and the top and bottom of the clamping bracket 32 ​​are provided with protruding rods 34, and the top and bottom of the groove 33 of the movable bracket 5 are provided with positioning grooves 35 that slide with the protruding rod 34. The fixing rod 4 is limited in rotation by the limiting nut 21. At this time, the fixing rod 4 pulls the movable frame gradually close to the second bracket 2. At this time, the movable frame 5 uses the clamping frame 32 to drive the connecting frame 31 to move synchronously. The connecting frame 31 drives the second slider 28 to slide inside the limiting groove 24 through the second groove 30 until one end of the connecting frame 31 is at the front side end of the second groove 30. At this time, the fixing rod 4 cannot continue to move inside the second bracket 2. The buckle of the connecting frame 31 and the second groove 30 and the spiral cooperation of the limiting nut 21 and the fixing rod 4 facilitate the fixing of the limiting frame 5. When the clamping frame 32 drives the second slider 28 to move by the connecting frame 31, the second slider 28 cooperates with the limiting inside the limiting groove 24. The two connecting frames 31 gradually approach each other during the sliding process, and the connecting frame 31 pushes the clamping frame 32 to slide inside the groove 33 until the clamping frame 32 is at the inner end position of the groove 33.

[0037] When the external impact force acts on the movable frame 5 through the fixed rod 4, the movable frame 5 drives the connecting frame 31 to move by the clamping frame 32, and the connecting frame 31 uses the second groove 30 to make the second slider 28 move inside the limiting groove 24. When the clamping frame 32 drives the connecting frame 31 to move, the second slider 28 uses the connecting frame 31 to pull the clamping frame 32 to slide inside the groove 33. At this time, the two clamping frames 32 gradually move away from each other during the movement. Under the impact force, the movable frame 5 drives the intermediate frame 22 to move by the rotating rod 6. At this time, the intermediate frame 22 uses the two second rotating plates 26 to make the two first sliders 25 move inside the limiting groove 24. At this time, the first slider 25 and the second slider 28 squeeze the second spring 29 during the sliding process, and the elastic force of the second spring 29 is used to absorb the impact force acting on the movable frame 5.

[0038] Working principle of the present invention:

[0039] Refer to the instruction manual Figure 1-4When installing the bumper 3, the limiting nut 21 is rotated, and the limiting nut 21 and the fixing rod 4 are screwed together to move the fixing rod 4, and the fixing rod 4 pulls the movable frame 5 to move until the movable frame 5 cannot move, which is convenient for limiting the relative distance between the first bracket 1 and the second bracket 2. When the bumper 3 is installed on the first bracket 1, due to the limitation of the limiting nut 21 on the fixing rod 4, the first bracket 1 cannot slide on the second bracket 2 using the fixing rod 4. When the rotating rod 6 is rotated, the movable block 9 and the two first rotating plates 12 are used to adjust the positions of the two moving frames 11, which is convenient for real-time adjustment of the position of the clamp 7, thereby ensuring the stability of the installation of the bumper 3. When the movable frame 11 clamps the bumper 3 using the clamp 7 at the end of the screw 16, the front side of the clamp 7 contacts the rear side of the bumper 3. At this time, the top and bottom of the bumper 3 can be wrapped around the surface of the first bracket 1. Driven by the movable frame 11, the two clamps 7 are gradually inserted into the first slot 8. With the cooperation of the clamp 7 and the inclined surface 801 of the first slot 8, the bumper 3 gradually approaches the first bracket 1 until the clamp 7 is completely corresponding to the first bracket 1, thereby completing the quick installation of the bumper 3.

[0040] When the bumper 3 needs to be disassembled quickly, the rotating rod 6 is rotated in the opposite direction. The spiral effect of the rotating rod 6 and the movable frame 5 pushes the movable block 9 to gradually approach the first bracket 1. The positions of the two movable frames 11 are adjusted by utilizing the movable block 9 and the two first rotating plates 12. The two movable frames 11 slide inside the slide groove 13 under the push of the first rotating plates 12. The two movable frames 11 gradually move away from each other during the sliding process. At this time, the two movable frames 11 drive the clamp 7 to gradually separate from the first slot 8, making it convenient to remove the bumper 3 from the first bracket 1, thereby ensuring the quick disassembly effect of the bumper 3.

[0041] When external impact force acts on the bumper 3, the bumper 3 facilitates the clamp 7 to push the screw 16 to move. When the screw 16 slides on the surface of the square rod 19 using the square groove 20, the rear end of the screw 16 squeezes the first spring 18 inside the second slot 17. The elastic force of the first spring 18 can reduce the impact force of the bumper 3 on the first bracket 1, and at the same time avoid the bumper 3 directly impacting the first bracket 1, thereby reducing the impact damage between the bumper 3 and the first bracket 1.

[0042] The force acting on the bumper 3 is transmitted to the fixed rod 4 through the first bracket 1. When the external impact force acts on the movable frame 5 through the fixed rod 4, the movable frame 5 drives the connecting frame 31 to move by using the clamping frame 32. The connecting frame 31 uses the second groove 30 to make the second slider 28 move inside the limiting groove 24. When the clamping frame 32 drives the connecting frame 31 to move, the second slider 28 uses the connecting frame 31 to pull the clamping frame 32 to slide inside the groove 33. At this time, the two clamping frames 32 gradually move away from each other during the movement. Under the impact force, the movable frame 5 drives the intermediate frame 22 to move by using the rotating rod 6. At this time, the intermediate frame 22 uses the two second rotating plates 26 to make the two first sliders 25 move inside the limiting groove 24. At this time, the first slider 25 and the second slider 28 squeeze the second spring 29 during the sliding process. The elastic force of the second spring 29 is used to absorb the impact force acting on the movable frame 5, thereby preventing the external impact force from acting on the vehicle body, thereby reducing the damage to the vehicle body.
