Description
Technical Field
[0001] The invention relates to the technical field of automobiles, in particular to an impact-resistant combined rear anti-collision beam for automobiles. Background Art
[0002] With the continuous development of the economy, cars have become the main means of transportation for people's daily travel and cargo transportation. The number of cars has shown a trend of rapid growth year by year. Against the background of increasingly busy road traffic, the frequency of traffic accidents has also remained high, among which rear-end collisions between vehicles account for a considerable proportion. Rear-end collisions often cause varying degrees of damage to the rear structure of the vehicle, which in turn affects the life safety of passengers in the car and the subsequent normal use of the vehicle. Therefore, as a key component in the vehicle's passive safety system, the performance of the rear anti-collision beam of the car plays a vital role in reducing the damage caused by rear-end collisions.
[0003] Traditional rear anti-collision beams of automobiles mostly adopt a relatively simple structure and a single material. For example, some anti-collision beams are only composed of a solid steel beam. When hit, they mainly rely on the strength of the steel itself to resist the impact force. They lack effective buffering and energy absorption mechanisms. In addition, this anti-collision beam structure is too integrated. Once a component is damaged, the repair cost is high and difficult. Summary of the invention
[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: an impact-resistant combined rear anti-collision beam for automobiles, comprising: An anti-collision beam shell, wherein the anti-collision beam shell is in an arc shape as a whole, and its impact surface is also in an arc shape. A clamping strip is fixedly installed on the inner wall of the anti-collision beam shell, and clamping grooves are provided on both sides of the clamping strip. An arc-shaped fixing plate is detachably installed on the inner bending surface of the anti-collision beam shell through bolts; An anti-collision component, which is detachably mounted inside the anti-collision beam housing through a clip to cushion the impact force and mitigate the impact; Energy absorbing components, which are installed on both sides of the surface of the arc-shaped fixed plate and are used to absorb the impact force when the vehicle is hit; Among them, the anti-collision component includes a clamping component, which is detachably mounted on the outer surface of the clamping strip, and the outer surface of the clamping component is fixedly connected to the top of the support plate surface, the support plate and the arc-shaped fixed plate are extruded and adapted, and a telescopic buffer component is installed in the middle of the support plate surface, and the end of the telescopic buffer component away from the support plate is fixedly connected to a connecting plate, and a first buffer spring is also fixedly connected between the connecting plate and the opposite surface of the support plate, and the first buffer spring is arranged on both sides of the telescopic buffer component, and a rubber block is fixedly mounted on the outer surface of the connecting plate, and the rubber block is extruded and adapted to the anti-collision beam shell, and when the rear anti-collision beam is hit, the rubber block can buffer the impact force by its own deformation and cooperation with the first buffer spring to disperse the impact energy.
[0005] Preferably, fixing plates are fixedly installed on the opposite surfaces of the two energy absorbing components, and an arc-shaped support plate is fixedly connected between the fixing plates. The arc-shaped support plate and the middle part of the arc-shaped fixing plate are squeezed and adapted, and the arc radius of the arc-shaped support plate is smaller than the arc radius of the arc-shaped fixing plate. When the anti-collision beam shell has a tendency to bend, the arc-shaped support plate squeezes the arc-shaped fixing plate to give the anti-collision beam shell a reverse supporting force, thereby enhancing the bending resistance of the overall structure.
[0006] Preferably, a steel cable is fixedly connected between the arc support plate and the fixed plate. There are two steel cables, and the two steel cables are fixedly connected in the middle of the concave surface of the arc support plate. The steel cables apply tension to the arc support plate in two symmetrical directions to assist the arc support plate in functioning and maintain structural stability.
[0007] Preferably, the clamping component includes a clamping block, the outer surface of which is provided with a clamping slot, the clamping slot is clamped and matched with a clamping strip, and the two sides of the clamping slot are provided with a receiving slot, a clamping strip is slidably installed inside the receiving slot, the clamping strip is clamped and matched with the clamping slot, and a reset spring is fixedly connected between the clamping strip and the receiving slot. On the basis of the clamping slot and the clamping strip being locked, the clamping strip is clamped and matched with the clamping slot under the action of the reset spring, so that the entire anti-collision component is locked and installed inside the anti-collision beam housing, which is convenient for assembly and maintenance.
[0008] Preferably, the telescopic buffer component includes a sleeve, which is fixedly connected to the surface of the support plate, and one end of the sleeve away from the support plate is fixedly connected to a limiting ring, the interior of the sleeve is slidably connected to a sliding rod, and the sliding rod is arranged inside the limiting ring, one end of the sliding rod is fixedly connected to a limiting disk, the limiting disk and the limiting ring are extruded and adapted, and a second buffer spring is fixedly connected between the limiting disk and the sleeve. When a collision occurs, the sliding rod can slide in the sleeve, and the second buffer spring absorbs energy, thereby buffering the impact force and alleviating the impact effect.
[0009] Preferably, the energy absorbing assembly includes a fixing rod and a box body, the fixing rod is fixedly connected to the outer surface of the arc-shaped fixing plate, one end of the fixing rod away from the arc-shaped fixing plate is fixedly connected to a trapezoidal push block, a sliding block is fixedly installed on the outer surface of the trapezoidal push block, and sliding grooves are provided on both sides of the sliding block.
[0010] Preferably, slide rails are fixedly installed on both sides of the box body, and the sliding block is slidably installed inside the box body through the slide rails. The ends of the slide rails are fixedly connected with baffles, which are squeezed and adapted with the sliding block to prevent the sliding block from sliding out.
[0011] Preferably, an energy absorbing spring is fixedly connected between the sliding block and the box body. The energy absorbing spring is evenly arranged at the corners of the inner wall of the box body. During the sliding process of the sliding block, the energy absorbing spring absorbs the impact energy by shrinking and deforming, thereby playing an energy absorbing and buffering role.
[0012] Preferably, a trapezoidal box body is fixedly installed on one side of the box body, the trapezoidal box body penetrates the box body and extends into the interior thereof, the trapezoidal box body is squeezed and adapted with the trapezoidal push block, and a mounting plate is fixedly connected to the side of the trapezoidal box body away from the box body, and the mounting plate facilitates the installation and connection of the entire energy absorbing assembly with other parts of the vehicle.
[0013] Preferably, a diamond-shaped dense plate is fixedly installed inside the trapezoidal box body. When the rear anti-collision beam is squeezed, the diamond-shaped dense plate inside the trapezoidal box body collapses and absorbs energy, thereby effectively consuming the impact energy.
[0014] The present invention provides an impact-resistant combined rear anti-collision beam for automobiles, which has the following beneficial effects: 1. The impact-resistant combined rear anti-collision beam of an automobile is provided with an anti-collision component. When the rear of the vehicle is hit, the convex arc-shaped impact surface of the anti-collision beam shell is first exposed to the impact force. Due to the impact force, the convex arc-shaped side surface of the anti-collision beam shell begins to be squeezed and deformed, and the inner wall of the anti-collision beam shell begins to squeeze the rubber block. When the rubber block is squeezed, it deforms itself and transmits the force received to the first buffer spring connected thereto. The first buffer spring converts the impact force into elastic potential energy of the spring for storage, thereby buffering a part of the impact force and driving the connecting plate to move in the process. At this time, the sliding rod slides inside the sleeve, and the second buffer spring contracts. The impact force is buffered and absorbed by the conversion of elastic potential energy, and the rubber block and the first buffer spring are used to jointly reduce the impact force caused by the initial impact, which greatly reduces the impact force borne by the vehicle and the occupants at the moment of the collision, thereby improving the safety of the ride.
[0015] 2. The impact-resistant combined rear anti-collision beam of an automobile is provided with an energy-absorbing component. When the impact force acts on the anti-collision beam shell, the anti-collision beam shell will move as a whole, and the anti-collision beam shell will drive the arc-shaped fixed plate and the energy-absorbing component to move. The fixing rod moves with the arc-shaped fixed plate, and the trapezoidal push block fixedly connected to the end of the fixing rod away from the arc-shaped fixed plate also moves synchronously and squeezes the trapezoidal box body. After the trapezoidal box body is squeezed, the diamond-shaped dense plate fixedly installed inside it begins to collapse and absorb energy due to the pressure, thereby reducing the impact force transmitted to the rear of the vehicle. The sliding block slides inside the box body, and the energy-absorbing spring fixedly connected between the sliding block and the box body is compressed. Relying on the elastic deformation of the energy-absorbing spring, part of the impact energy is absorbed, which works together with the collapse energy absorption of the trapezoidal box body and the diamond-shaped dense plate inside it to continuously reduce the impact of the impact force on the vehicle.
[0016] 3. The impact-resistant combined rear anti-collision beam of an automobile is detachably connected to the anti-collision component through the setting of the clamping component and the clamping strip on the inner wall of the anti-collision beam shell. The clamping groove on the outer surface of the clamping block in the clamping component is clamped and matched with the clamping strip. The clamping strip is clamped and matched with the clamping grooves on both sides of the clamping strip under the action of the reset spring. This design enables the anti-collision component to be firmly fixed inside the anti-collision beam shell during installation, ensuring that it will not easily loosen and fall off during normal use. When a component in the anti-collision component is damaged, the maintenance personnel only need to press the clamping strip to overcome the elastic force of the reset spring and disengage from the clamping groove, so as to conveniently remove the entire anti-collision component from the anti-collision beam shell, thereby greatly reducing the difficulty and cost of maintenance.
[0017] 4. The impact-resistant combined rear anti-collision beam of an automobile is provided with an arc-shaped support plate. When the anti-collision beam shell shows a bending tendency, the arc-shaped support plate will interact with the arc-shaped fixing plate. Since the middle part of the arc-shaped support plate and the arc-shaped fixing plate is squeezed and adapted to each other, a reverse squeezing force will be applied to the arc-shaped fixing plate. This squeezing force can counteract the bending deformation tendency of the anti-collision beam shell, help maintain the shape of the overall structure of the anti-collision beam, keep it in its original state as much as possible, and prevent excessive bending from affecting its anti-collision function. At the same time, the steel cable will provide the arc-shaped support plate with pulling forces in two symmetrical directions. These two pulling forces cooperate with the squeezing force of the arc-shaped support plate on the arc-shaped fixing plate, further enhancing the resistance to bending of the anti-collision beam shell and ensuring the stability of the entire anti-collision beam structure under complex stress conditions.
[0018] 5. The impact-resistant combined rear anti-collision beam of the automobile, through the overall arc-shaped anti-collision beam shell and the coordination of various internal buffering and energy-absorbing components, can cope with different situations such as head-on collision and collision at a certain angle through the coordination of various components, thereby improving the adaptability of the anti-collision beam to different collision conditions.

The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
[0022] The first embodiment, as Figures 1 to 5 As shown, the present invention provides a technical solution: an impact-resistant combined rear anti-collision beam for automobiles, comprising: The anti-collision beam housing 1 is in an arc shape as a whole, and its impact surface is also in an arc shape. A clamping strip 8 is fixedly installed on the inner wall of the anti-collision beam housing 1, and clamping grooves 9 are provided on both sides of the clamping strip 8. An arc-shaped fixing plate 3 is detachably installed on the surface of the anti-collision beam housing 1 by bolts; The anti-collision component 2 is detachably mounted inside the anti-collision beam housing 1 through a clamping strip 8 to buffer the impact force and mitigate the impact; Among them, the anti-collision component 2 includes a clamping component 25, which is detachably mounted on the outer surface of the clamping strip 8, and the outer surface of the clamping component 25 is fixedly connected to the top of the surface of the support plate 21, and the support plate 21 is extruded and adapted with the arc-shaped fixed plate 3. A telescopic buffer component 26 is installed in the middle of the surface of the support plate 21, and the end of the telescopic buffer component 26 away from the support plate 21 is fixedly connected with a connecting plate 22, and a first buffer spring 24 is also fixedly connected between the connecting plate 22 and the opposite surface of the support plate 21. A rubber block 23 is fixedly mounted on the outer surface of the connecting plate 22, and the rubber block 23 is extruded and adapted with the anti-collision beam shell 1. When the rear anti-collision beam is hit, the rubber block 23 can buffer the impact force by its own deformation and cooperation with the first buffer spring 24 to disperse the impact energy; The clamping component 25 includes a clamping block 251, the outer surface of which is provided with a clamping slot 252, which is clamped and matched with the clamping strip 8, and two sides of the clamping slot 252 are provided with a receiving slot 253, and a clamping strip 255 is slidably installed inside the receiving slot 253, which is clamped and matched with the clamping slot 9, and a reset spring 254 is fixedly connected between the clamping strip 255 and the receiving slot 253. On the basis of the clamping slot 252 being locked with the clamping strip 8, the clamping strip 255 is clamped and matched with the clamping slot 9 under the action of the reset spring 254, so that the entire anti-collision component 2 is locked and installed inside the anti-collision beam housing 1, which is convenient for assembly and maintenance, etc.; The telescopic buffer component 26 includes a sleeve 261, which is fixedly connected to the surface of the support plate 21. One end of the sleeve 261 away from the support plate 21 is fixedly connected to a limiting ring 264. The interior of the sleeve 261 is slidably connected with a sliding rod 262. One end of the sliding rod 262 is fixedly connected to a limiting disk 263. The limiting disk 263 is squeezed and adapted with the limiting ring 264. A second buffer spring 265 is fixedly connected between the limiting disk 263 and the sleeve 261. When an impact occurs, the sliding rod 262 can slide in the sleeve 261, and the second buffer spring 265 is used to absorb energy, thereby buffering the impact force and alleviating the impact effect.
[0023] The second embodiment is based on the first embodiment. Figures 1 to 8 As shown, the energy absorbing assembly 4 is installed on both sides of the surface of the arc-shaped fixing plate 3 to absorb the impact force when the vehicle is hit; The energy absorbing assembly 4 includes a fixing rod 401 and a box body 405. The fixing rod 401 is fixedly connected to the outer surface of the arc-shaped fixing plate 3. One end of the fixing rod 401 away from the arc-shaped fixing plate 3 is fixedly connected to a trapezoidal push block 402. A sliding block 403 is fixedly installed on the outer surface of the trapezoidal push block 402. Slide grooves 404 are provided on both sides of the sliding block 403. Slide rails 406 are fixedly installed on both sides of the box body 405, and the sliding block 403 is slidably installed inside the box body 405 through the slide rails 406. The ends of the slide rails 406 are fixedly connected with baffles 411, which are pressed and adapted with the sliding block 403 to prevent the sliding block 403 from sliding out; An energy absorbing spring 407 is fixedly connected between the sliding block 403 and the box body 405. The energy absorbing spring 407 is evenly arranged at the corners of the inner wall of the box body 405. During the sliding process of the sliding block 403, the energy absorbing spring 407 absorbs the impact energy by shrinking and deforming, thereby playing an energy absorbing and buffering role. A trapezoidal box body 408 is fixedly installed on one side of the box body 405. The trapezoidal box body 408 penetrates the box body 405 and extends into the interior thereof. The trapezoidal box body 408 is pressed and adapted with the trapezoidal push block 402. A mounting plate 410 is fixedly connected to one side of the trapezoidal box body 408 away from the box body 405. The mounting plate 410 facilitates the installation and connection of the entire energy absorbing assembly 4 with other parts of the vehicle. A diamond-shaped dense plate 409 is fixedly installed inside the trapezoidal box body 408. When the rear anti-collision beam is squeezed, the diamond-shaped dense plate 409 inside the trapezoidal box body 408 collapses and absorbs energy, thereby effectively consuming the impact energy.
[0024] The third embodiment is based on the first and second embodiments. Figure 1 As shown, the opposite surfaces of the two energy absorbing components 4 are fixedly installed with fixing plates 6, and the fixing plates 6 are fixedly connected with arc-shaped support plates 5, which are squeezed and adapted with the middle of the arc-shaped fixing plates 3, and the arc radius of the arc-shaped support plate 5 is smaller than the arc radius of the arc-shaped fixing plate 3. When the anti-collision beam shell 1 has a bending tendency, the arc-shaped support plate 5 squeezes the arc-shaped fixing plate 3, giving the anti-collision beam shell 1 a reverse supporting force, thereby enhancing the bending resistance of the overall structure; A steel cable 7 is fixedly connected between the arc support plate 5 and the fixed plate 6. There are two steel cables 7, and the two steel cables 7 are fixedly connected in the middle of the concave surface of the arc support plate 5. The steel cables 7 apply tension in two symmetrical directions to the arc support plate 5 to assist the arc support plate 5 in functioning and maintain structural stability.
[0025] When in use, the card slots 252 on the outer surface of the card block 251 in the card component 25 are carded and adapted with the card strip 8, and the card strips 255 in the receiving grooves 253 on both sides of the card slot 252 are carded and adapted with the card slots 9 on both sides of the card strip 8 under the action of the return spring 254, and the installation of the anti-collision component 2 is completed, and then the arc-shaped fixing plate 3 and the energy absorbing component 4 are installed and connected to other parts of the vehicle body; When the rear of the vehicle is hit, the convex arc-shaped impact surface of the anti-collision beam shell 1 is first exposed to the impact force. Due to the impact force, the convex arc-shaped side surface of the anti-collision beam shell 1 begins to be squeezed and deformed, and the inner wall of the anti-collision beam shell 1 begins to squeeze the rubber block 23. The rubber block 23 deforms itself when squeezed, and at the same time transmits the force to the first buffer spring 24 connected to it. The first buffer spring 24 converts the impact force into elastic potential energy of the spring for storage, thereby buffering part of the impact force, and in the process drives the connecting plate 22 to move. At this time, the sliding rod 262 slides inside the sleeve 261, and the second buffer spring 265 begins to shrink, and also further buffers and absorbs the impact force through the conversion of elastic potential energy, and cooperates with the rubber block 23 and the first buffer spring 24 to reduce the impact force caused by the initial impact.
[0026] When the impact force acts on the anti-collision beam shell 1, the anti-collision beam shell 1 will move as a whole, and the anti-collision beam shell 1 will drive the arc-shaped fixing plate 3 and the energy absorption component 4 to move. The fixing rod 401 moves with the arc-shaped fixing plate 3, and the trapezoidal push block 402 fixedly connected to the end of the fixing rod 401 away from the arc-shaped fixing plate 3 also moves synchronously and squeezes the trapezoidal box body 408. After the trapezoidal box body 408 is squeezed, the diamond-shaped dense plate 409 fixedly installed inside it begins to collapse and absorb energy due to the pressure, thereby reducing the impact force transmitted to the rear of the vehicle.
[0027] At the same time, the sliding block 403 slides inside the box body 405, and the energy-absorbing spring 407 fixedly connected between the sliding block 403 and the box body 405 is compressed. Relying on the elastic deformation of the energy-absorbing spring 407, a part of the impact energy is further absorbed, and together with the deformation energy absorption of the trapezoidal box body 408 and its internal diamond dense plate 409, the impact of the impact force on the vehicle is continuously weakened.
[0028] When the anti-collision beam shell 1 shows a tendency to bend, the arc-shaped support plate 5 will interact with the arc-shaped fixing plate 3. Since the arc-shaped support plate 5 and the arc-shaped fixing plate 3 are squeezed and adapted to each other in the middle, a reverse squeezing force will be applied to the arc-shaped fixing plate 3. This squeezing force can counteract the bending deformation tendency of the anti-collision beam shell 1, help maintain the shape of the overall structure of the anti-collision beam, keep it in its original state as much as possible, and prevent excessive bending from affecting its anti-collision function. At the same time, the steel cable 7 will provide the arc-shaped support plate 5 with pulling forces in two symmetrical directions. These two pulling forces cooperate with the squeezing force of the arc-shaped support plate 5 on the arc-shaped fixing plate 3 to further enhance the resistance to bending of the anti-collision beam shell 1 and ensure the stability of the entire anti-collision beam structure under complex stress conditions.
[0029] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
