Description

Technical Field

[0001] This utility model belongs to the field of energy-absorbing box technology, specifically relating to a combined automotive collision energy-absorbing box. Background Technology

[0002] With the rapid development of the automotive industry, people's demand for cars is on the rise. The increase in the number of cars on the road has also increased the probability of traffic accidents. As part of the bumper, the energy-absorbing box is crucial to car safety.

[0003] Car collision energy-absorbing boxes utilize the kinetic energy gained from a collision to convert it into deformation energy, thereby protecting the safety of passengers and pedestrians.

[0004] Most automotive collision energy absorption boxes still use simple thin-walled structures in the form of round or square tubes, resulting in low energy absorption efficiency and excessively high peak forces. With the improvement of vehicle power, existing thin-walled energy absorption boxes have a low impact resistance capacity and cannot effectively protect vehicles and pedestrians. Therefore, this application proposes a combined automotive collision energy absorption box. Utility Model Content

[0005] The purpose of this invention is to provide a combined automotive collision energy-absorbing box to solve the problem mentioned in the background art that the existing thin-walled energy-absorbing boxes have low impact resistance and cannot effectively protect vehicles and pedestrians.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a combined automotive collision energy-absorbing box, comprising a first flange, an energy-absorbing column, and a second flange, wherein the first flange and the second flange are respectively installed at both ends of the energy-absorbing column; The energy-absorbing column comprises a hollow column. The energy-absorbing column is equipped with a reinforcing plate, and several reinforcing rods are inserted into the reinforcing plate; The energy-absorbing column is provided with a positioning bolt and a positioning hole provided on the energy-absorbing column and cooperating with the positioning bolt; the reinforcing plate is provided with an installation hole that cooperates with the positioning bolt. A locking assembly is provided at the reinforcing plate. The locking assembly includes a locking plate, a spring connected to the locking plate, a trapezoidal push plate mounted on the locking plate and having a first inclined surface on its top, and a trapezoidal pressure plate having a second inclined surface that fits against the first inclined surface inside. A lifting plate is provided at the trapezoidal pressure plate, and the lifting plate slides in conjunction with the mounting hole.

[0007] Preferably, the first flange includes a vertical plate and an inclined plate, and the vertical plate and the inclined plate are smoothly connected.

[0008] Preferably, the column is provided with a plurality of inwardly recessed transverse grooves and a plurality of inwardly recessed longitudinal grooves.

[0009] Preferably, the sidewall of the column includes two transverse surfaces and two longitudinal surfaces, with transverse grooves disposed on the two transverse surfaces and longitudinal grooves disposed on the two longitudinal surfaces.

[0010] Preferably, the transverse grooves and longitudinal grooves are distributed at intervals.

[0011] Preferably, the energy-absorbing column is provided with an arc-shaped recess at the position corresponding to the longitudinal groove, and after the positioning bolt is screwed into the mounting hole, the trapezoidal push plate abuts against the arc-shaped recess.

[0012] Preferably, the locking plate is provided with a slider, the reinforcing plate is provided with a groove that slides with the slider, and the cross-section of the slider is set to L shape.

[0013] Preferably, there are two locking plates, and the two locking plates are symmetrically distributed about the center line of the mounting hole.

[0014] Preferably, one end of the spring is connected to the locking plate, and the other end of the spring is connected to the reinforcing plate. The spring is used to apply a force to the locking plate to move away from the arc-shaped recess.

[0015] Preferably, a pressure block is provided on the upper side of the trapezoidal pressure plate, the pressure block is connected to the lifting plate, and a vertical groove is provided in the reinforcing plate to slide with the pressure block, the vertical groove being aligned with the mounting hole.

[0016] Beneficial effects: I. The combined automotive collision energy-absorbing box provided by this utility model has multiple transverse and longitudinal grooves on the energy-absorbing column. Both the transverse and longitudinal grooves are recessed inward. When the energy-absorbing column is impacted, the transverse and longitudinal grooves allow the energy-absorbing column to bend along the recessed transverse and longitudinal grooves, allowing the energy-absorbing column to bend at an angle. This reduces the impact on the vehicle body (first flange end) after the bumper (second flange end) is impacted, effectively protecting the vehicle body. At the same time, the transverse and longitudinal grooves cause the energy-absorbing column to bend at an angle. This twisted energy-absorbing column can withstand part of the impact force, and the impact force on objects and people hit by the bumper is also reduced accordingly, which can reduce the degree of damage to objects and people.

[0017] 2. Insert the reinforcing plate into the corresponding position inside the energy-absorbing column, and then screw the positioning bolt through the positioning hole into the mounting hole in the reinforcing plate. In this way, the reinforcing plate is fixed to the energy-absorbing column under the action of the positioning bolt. When subjected to impact, the reinforcing plate and reinforcing rod inside the energy-absorbing column can support the energy-absorbing column, increasing the strength of the energy-absorbing column and its ability to absorb impact force.

[0018] Third, by setting a locking component on the reinforcing plate, after the reinforcing plate and reinforcing rod are sent into the energy-absorbing column, the positioning bolt is screwed into the mounting hole to complete the positioning of the reinforcing plate. During the process of the positioning bolt entering the mounting hole, it will squeeze the lifting plate. The lifting plate can push the trapezoidal push plate and the locking plate to move through the trapezoidal pressure plate, so that the locking plate is pressed against the arc-shaped recess inside the energy-absorbing column. In this way, the locking plate can position the reinforcing plate. When it is impacted, the impact force can be transferred to the reinforcing plate through the locking plate and other components, thereby enhancing the energy-absorbing column's ability to absorb impact force.

Detailed Implementation

[0021] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0022] like Figures 1-5 As shown, the combined automotive collision energy-absorbing box provided in this embodiment of the utility model includes a first flange 1, an energy-absorbing column 2, and a second flange 3. The first flange 1 and the second flange 3 are respectively installed at both ends of the energy-absorbing column 2. The first flange 1 includes a vertical plate and an inclined plate, which are smoothly connected. The vertical plate and the inclined plate fit snugly against the installation part on the vehicle body. Since the installation position on the vehicle body is not a simple vertical surface, in order to fit snugly against the vehicle body, the first flange 1 is set to be an integral shape of the vertical plate and the inclined plate, so that it can fit snugly against the vehicle body and play a supporting role.

[0023] For details, please refer to Figure 2The energy-absorbing column 2 includes a hollow column 201. The column 201 is provided with a number of inwardly recessed transverse grooves 202 and a number of inwardly recessed longitudinal grooves 203. The sidewall of the column 201 includes two transverse surfaces and two longitudinal surfaces. The transverse grooves 202 are provided on the two transverse surfaces and the longitudinal grooves 203 are provided on the two longitudinal surfaces. It should be noted that the transverse grooves 202 and the longitudinal grooves 203 are distributed alternately.

[0024] Multiple transverse grooves 202 and longitudinal grooves 203 are provided on the energy-absorbing column 2. Both the transverse grooves 202 and longitudinal grooves 203 are recessed inward. When the energy-absorbing column 2 is impacted, the transverse grooves 202 and longitudinal grooves 203 allow the energy-absorbing column 2 to bend along the recessed transverse grooves 202 and longitudinal grooves 203, allowing the energy-absorbing column 2 to bend at an angle. This reduces the impact on the vehicle body (one end of the first flange 1) after the bumper (one end of the second flange 3) is impacted, effectively protecting the vehicle body. At the same time, the transverse grooves 202 and longitudinal grooves 203 cause the energy-absorbing column 2 to bend at an angle. In this twisted state, the energy-absorbing column 2 can withstand part of the impact force, and the impact force on objects and people hit by the bumper is also reduced accordingly, which can reduce the degree of damage to objects and people.

[0025] To enhance the strength of the energy-absorbing column 2, a reinforcing plate 4 is provided inside the energy-absorbing column 2. Several reinforcing rods 5 are inserted into the reinforcing plate 4. One end of the reinforcing rod 5 abuts against the first flange 1, and the other end of the reinforcing rod 5 abuts against the second flange 3.

[0026] In order to fix the energy-absorbing column 2 to the reinforcing plate 4, a positioning bolt 6 is provided at the energy-absorbing column 2, and a positioning hole is provided on the energy-absorbing column 2 to cooperate with the positioning bolt 6. An installation hole is provided in the reinforcing plate 4 to cooperate with the positioning bolt 6.

[0027] Insert the reinforcing plate 4 into the corresponding position inside the energy-absorbing column 2, and then screw the positioning bolt 6 through the positioning hole into the mounting hole in the reinforcing plate 4. In this way, the reinforcing plate 4 is fixed to the energy-absorbing column 2 under the action of the positioning bolt 6. When subjected to impact, the reinforcing plate 4 and reinforcing rod 5 inside the energy-absorbing column 2 can support the energy-absorbing column 2, increasing the strength of the energy-absorbing column 2 and its ability to absorb impact force.

[0028] In order to increase the number of connection points between the reinforcing plate 4 and the energy-absorbing column 2, so that the reinforcing plate 4 can bear the force when the energy-absorbing column 2 is impacted, a locking component 7 is provided at the reinforcing plate 4. The locking component 7 includes a locking plate 701, a spring 702 connected to the locking plate 701, a trapezoidal push plate 703 installed on the locking plate 701 and having a first inclined surface on the top, and a trapezoidal pressure plate 704 with a second inclined surface that fits against the first inclined surface inside. A lifting plate is provided at the trapezoidal pressure plate 704. The lifting plate is set in the mounting hole and slides with the mounting hole.

[0029] During the process of screwing the positioning bolt 6 into the mounting hole, it will squeeze the lifting plate, causing the lifting plate to move downward. The trapezoidal pressure plate 704 connected to the lifting plate 704 will squeeze the first inclined surface of the trapezoidal push plate 703 through the second inclined surface. The squeezed trapezoidal push plate 703 will drive the locking plate 701 to move and abut against the inner wall of the energy-absorbing column 2. It should be noted that the energy-absorbing column 2 is provided with an arc-shaped recess at the position corresponding to the longitudinal groove 203. After the positioning bolt 6 is screwed into the mounting hole, the trapezoidal push plate 703 abuts against the arc-shaped recess.

[0030] Specifically, a slider is provided at the locking plate 701, and a groove is provided in the reinforcing plate 4 to slide with the slider. The cross-section of the slider is L-shaped. There are two locking plates 701, and the two locking plates 701 are symmetrically distributed about the center line of the mounting hole.

[0031] More specifically, one end of the spring 702 is connected to the locking plate 701, and the other end of the spring 702 is connected to the reinforcing plate 4. The spring 702 can be a metal spring with a length of 2cm and a wire diameter of 8mm. The spring 702 is used to give the locking plate 701 a force to move away from the arc-shaped recess. In this way, when the positioning bolt 6 does not press the lifting plate, the locking plate 701 will be pulled away from the arc-shaped recess by the elastic force of the spring 702. Thus, the reinforcing plate 4 will not be obstructed by the arc-shaped recess when entering the energy-absorbing column 2 or moving out of the energy-absorbing column 2.

[0032] Specifically, a pressure block 705 is provided on the upper side of the trapezoidal pressure plate 704. The pressure block 705 is connected to the lifting plate. A vertical groove is provided in the reinforcing plate 4 to slide with the pressure block 705. The vertical groove is aligned with the mounting hole.

[0033] In summary, this utility model embodiment provides a combined automotive collision energy-absorbing box. Multiple transverse grooves 202 and longitudinal grooves 203 are provided on the energy-absorbing column 2. Both the transverse and longitudinal grooves 202 and 203 are recessed inwards. When the energy-absorbing column 2 is impacted, the transverse and longitudinal grooves 202 and 203 allow the energy-absorbing column 2 to bend along the recessed grooves, thus reducing the impact on the vehicle body (one end of the first flange 1) after the bumper (one end of the second flange 3) is impacted, effectively protecting the vehicle body. Simultaneously, the transverse and longitudinal grooves 202 and 203 cause the energy-absorbing column 2 to bend, allowing the twisted energy-absorbing column 2 to withstand some of the impact force. The impact force on objects and people hit by the bumper is also reduced accordingly, thus minimizing the damage to objects and people.

[0034] Insert the reinforcing plate 4 into the corresponding position inside the energy-absorbing column 2, and then screw the positioning bolt 6 through the positioning hole into the mounting hole in the reinforcing plate 4. In this way, the reinforcing plate 4 is fixed to the energy-absorbing column 2 under the action of the positioning bolt 6. When subjected to impact, the reinforcing plate 4 and reinforcing rod 5 inside the energy-absorbing column 2 can support the energy-absorbing column 2, increasing the strength of the energy-absorbing column 2 and its ability to absorb impact force.

[0035] By setting a locking component 7 on the reinforcing plate 4, after the reinforcing plate 4 and the reinforcing rod 5 are sent into the energy-absorbing column 2, the positioning bolt 6 is screwed into the mounting hole to complete the positioning of the reinforcing plate 4. During the process of the positioning bolt 6 entering the mounting hole, it will squeeze the lifting plate. The lifting plate can push the trapezoidal push plate 703 and the locking plate 701 to move through the trapezoidal pressure plate 704, so that the locking plate 701 abuts against the arc-shaped recess inside the energy-absorbing column 2. In this way, the locking plate 701 can position the reinforcing plate 4. When it is impacted, the impact force can be transferred to the reinforcing plate 4 through the locking plate 701 and other components, thereby enhancing the energy-absorbing column 2's ability to absorb impact force.

[0036] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
