[0024] 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.

[0025] like Figures 1 to 5 As shown, this utility model provides a vehicle bumper rear bumper with a warning structure, including a car 1 and a bumper body 2 fixedly connected to the rear side of the car 1. The surface of the bumper body 2 is fitted with an adaptive lifting device that follows the vehicle body and warning lights 5 embedded on both sides. A reflective strip 4 is provided between the interiors of the two sets of warning lights 5.

[0026] A retaining ring 3 is fitted on the surface of the bumper body 2. One end of the retaining ring 3 is fixedly connected to a first fixing frame 31, and the other end of the first fixing frame 31 is fixedly connected to a second fixing frame 38 via a straight rod. The left side first fixing frame 31 is equipped with a body-adaptive height adjustment component, and the second fixing frame 38 is equipped with an auxiliary body-adaptive height adjustment component.

[0027] In this implementation, the warning lights 5 are located on both sides of the bumper body 2, as shown in the figure. The length of the bumper body 2 is consistent with the width of the car body 1. The warning lights 5 can be used to indicate the width of the car at night, which is convenient for following vehicles. Adding reflective strips 4 on both sides of the warning lights 5 can solve the problem of warning failure caused by changes in vehicle load of traditional reflective strips 4.

[0028] Specifically, a sliding groove is provided on the fixing frame 31 near the retaining ring 3, and a limiting groove is provided on the top of the fixing frame 31. A sliding rod 33 is slidably connected inside the limiting groove of the fixing frame 31. A slider 32 is fixedly connected to the center of the surface of the sliding rod 33. The slider 32 slides inside the sliding groove of the fixing frame 31. A spring 34 is sleeved on the outside of the sliding rod 33 above the surface of the slider 32, and a spring 35 is sleeved on the outside of the sliding rod 33 below the surface of the slider 32. A partition is provided in the inner cavity of the fixing frame 31. A round hole groove is provided in the partition of the fixing frame 31. The spring 35 abuts against the surface of the round hole groove of the inner cavity partition of the fixing frame 31, and the fixing frame 31 passes through the inner cavity partition of the fixing frame 31 and slides inside the round hole groove.

[0029] In this example, when the connecting rod 311 is subjected to force and slides downward, it causes the slider 32 to slide downward synchronously. The slider 32 is fixedly connected to the first slider 33, which compresses the first spring 34 and causes the first slider 33 to slide downward synchronously. However, when the truck is lightly loaded, the downward pressure of the connecting rod 311 cannot overcome the resistance of the second spring 35. The second spring 35 rebounds and compresses the slider 32 to slide towards the first spring 34.

[0030] Furthermore, the bottom of the fixing frame 31 is inclined, and a horizontal bar 36 is pressed against the surface of the fixing frame 31. The other end of the horizontal bar 36 is pressed against a sliding rod 37. The sliding rod 37 passes through the fixing frame 38 and slides inside the fixing frame 38. A fixing rod 310 is sleeved on the surface of the sliding rod 37. A vertical groove is opened on the right side of the fixing frame 38. One end of the fixing rod 310 slides inside the vertical groove of the fixing frame 38. One end of the fixing rod 310 is fixedly connected to one side of the reflective strip 4.

[0031] In this example, when the slide bar 33 is subjected to force, it will slide out of the limiting groove of the fixing frame 31. A limiting ring is added to the surface of the slide bar 33 to prevent it from falling off when it slides out of the limiting groove of the fixing frame 31. The inclined surfaces of the slide bar 33 and the crossbar 36 are in opposite directions, and the inclined directions on both sides of the crossbar 36 are also in opposite directions. Referring to the attached picture ring 3, the inclined direction of the right side of the crossbar 36 and the inclined direction of the bottom end of the slide bar 37 are also in opposite positions. The overall force transmission method is "U" shaped.

[0032] It is worth noting that the internal structures of the first fixing frame 31 and the second fixing frame 38 are the same, both of which are equipped with partitions. The second fixing frame 38 has a fixed ring 39 fixedly connected inside. The second sliding rod 37 passes through the partition inside the second fixing frame 38 and slides inside the fixed ring 39. The fixed ring 39 is used to support and guide the second sliding rod 37. The second sliding rod 37 has a certain gap from the top of the second fixing frame 38, which facilitates the sliding of the second sliding rod 37 inside the second fixing frame 38.

[0033] It is worth mentioning that a connecting rod 311 is fixedly connected to one side of the slider 32, and the other end of the connecting rod 311 is rigidly connected to the crossbeam.

[0034] It is worth emphasizing that when the car is fully loaded and unloaded, there is a certain numerical difference in the height between the connection point of the bumper body 2 and the crossbeam and the ground.

[0035] Among them, the car 1, reflector strip 4, and warning light 5 are existing technologies and will not be described in detail; at the same time, this utility model also includes a power supply, controller, and switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, rear, left, and right" viewing angles of this device are... Figure 1 The direction shown in the diagram is the reference.

[0036] Working principle:

[0037] When the car 1 is heavily loaded, the weight of the cargo compresses the cargo box and the bumper body 2, causing them to slide downwards simultaneously. During the sliding process, the crossbeam, due to the weight of the cargo box, descends at a greater rate than the bumper body 2. The connecting rod 311 connected to the crossbeam descends simultaneously and slides downwards inside the first fixed frame 31. During the sliding process, the second spring 35 is compressed, causing the first sliding rod 33 to slide downwards from the limiting groove of the first fixed frame 31. During the sliding process, the first fixed frame 31 compresses the crossbar 36, causing it to shift towards the second fixed frame 38. The crossbar 36 compresses the second sliding rod 37, causing it to slide upwards inside the fixed ring 39. During the sliding process, the fixed rod 310 sleeved on the surface of the second sliding rod 37 slides in the vertical groove on the surface of the second fixed frame 38. During the sliding process, the fixed rod 310 causes the reflective strip 4 to slide upwards. The extent to which the reflective strip 4 rises is related to the weight received by the car 1.

[0038] When the car 1 is unloaded to the outside, the weight of the car 1 is reduced, and the slider 32 cannot overcome the resistance of the second spring 35. The slider 32 slides upward inside the first fixing frame 31. Since the first fixing frame 31 no longer squeezes the crossbar 36, the crossbar 36 returns to its original position. Meanwhile, the second slider 37 slides to the left under the action of gravity and returns to its original position. The reflector strip 4 slides downward at the same time and returns to the position on the surface of the bumper body 2 where the reflector strip 4 was in the previous empty state.
