Description

Technical Field

[0001] This invention relates to the field of energy-absorbing boxes, and in particular to a collision energy-absorbing box for new energy vehicles and its processing technology. Background Technology

[0002] The automotive collision avoidance energy absorption box is a core modular component of the vehicle's passive safety system. It is typically symmetrically installed between the front and rear bumper anti-collision beams and the vehicle's longitudinal beams, serving as the "first line of defense" for energy absorption during a collision. Its core function is to efficiently absorb collision energy through controlled plastic deformation along a pre-defined path, preventing the collision force from being directly transmitted to the vehicle's longitudinal beams, passenger compartment, or battery pack, thereby ensuring the safety of passengers and reducing post-accident repair costs.

[0003] When a common integrated anti-collision energy-absorbing box is partially damaged, the entire box needs to be replaced, which is wasteful. To address this problem, this invention proposes a detachable anti-collision energy-absorbing box. Summary of the Invention

[0015] Beneficial effects

[0016] 1. This invention provides a modular energy-absorbing box, including a first energy-absorbing component, a second energy-absorbing component, and a third energy-absorbing component. The first energy-absorbing component is fixed to the anti-collision beam by bolts, and the third energy-absorbing component is fixed to the vehicle frame by bolts. In the event of a minor collision, the first energy-absorbing component absorbs the energy generated by the collision. In the event of collisions of different levels, the first, second, and third energy-absorbing components absorb different levels of energy respectively. When a corresponding component undergoes local deformation during a collision, only the corresponding energy-absorbing component needs to be replaced locally, avoiding the waste of resources caused by replacing the entire component. In this invention, the clips used to fix each energy-absorbing component are set on the side, which can effectively avoid the problem of being unable to remove the component due to deformation caused by collision and squeezing.

[0017] 2. The present invention also includes an energy-absorbing box processing device for assembling the energy-absorbing box. When the first energy-absorbing component, the second energy-absorbing component, and the third energy-absorbing component are manually or mechanically fed, in order to avoid the end push plate being placed in front and obstructing the pushing of the first energy-absorbing component, the second energy-absorbing component, and the third energy-absorbing component, and also making the equipment occupy too large an area, the present invention provides a hidden end push plate, so that the end push plate is hidden inside the lower part of the equipment when not in use, so that the size of the equipment is reduced without affecting the feeding of each component.

[0018] 3. The energy-absorbing box processing device is equipped with a side fixing mechanism and an end alignment mechanism. The side fixing mechanism is used to grab the clips on the spliced ​​energy-absorbing box and insert the limiting pins on the clips into the limiting holes to realize the detachable splicing between the first energy-absorbing component, the second energy-absorbing component and the third energy-absorbing component. The end alignment mechanisms are located at both ends of the splicing bracket. After the first energy-absorbing component, the second energy-absorbing component and the third energy-absorbing component are placed on the splicing bracket, the first energy-absorbing component, the second energy-absorbing component and the third energy-absorbing component are aligned by the end alignment mechanisms. After alignment, the side fixing mechanism is used to install several clips. The various parts cooperate with each other to complete the overall assembly of the energy-absorbing box.

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figure 2 As shown in the figure, this embodiment of the invention provides a collision energy-absorbing box for new energy vehicles. Conventional energy-absorbing boxes are usually one-piece, requiring replacement of the entire box when damaged in a collision. However, in minor collisions, only partial damage occurs, making complete replacement wasteful. Therefore, this embodiment proposes a modular energy-absorbing box 100, including a first energy-absorbing component, a second energy-absorbing component, and a third energy-absorbing component. The first, second, and third energy-absorbing components are detachably connected to form a complete energy-absorbing box. The first and third energy-absorbing components are respectively installed at both ends of the second energy-absorbing component. In use, the first energy-absorbing component is bolted to the anti-collision beam, and the third energy-absorbing component is bolted to the vehicle frame. In a minor collision, the first energy-absorbing component absorbs the energy generated by the collision. In collisions of different levels, the first, second, and third energy-absorbing components absorb different levels of energy, such as... Figure 2As shown, the first energy-absorbing component includes a first connecting plate 101, on which a first energy-absorbing chamber 102 is fixedly mounted. The second energy-absorbing component includes a second energy-absorbing chamber 103, and the third energy-absorbing component includes a third energy-absorbing chamber 113 and a second connecting plate 104. A third connecting plate 105 is provided at one end of the first energy-absorbing chamber 102, and both ends of the second energy-absorbing chamber 103 are provided with third connecting plates 105. A third connecting plate 105 is also provided at one end of the third energy-absorbing chamber 113. Several third connecting plates 105 are provided at the points where the first, second, and third energy-absorbing components are fitted together. Figure 2 As shown, adjacent third connecting plates 105 are snapped together. The mating third connecting plates 105 are respectively provided with snap-fit ​​blocks 110 and snap-fit ​​slots 111. The snap-fit ​​between the snap-fit ​​slots 111 and the snap-fit ​​blocks 110 is achieved. Several adjacent third connecting plates 105 are spliced ​​together by snap-fit ​​strips 106, as shown. Figure 4 and Figure 5 As shown, each of the adjacent third connecting plates 105 is provided with several limiting holes, and the locking strip 106 is provided with two sets of limiting pins 112. The two sets of limiting pins 112 cooperate with the several limiting holes. In this embodiment, a total of four sets of locking strips 106 are provided. The first energy-absorbing component, the second energy-absorbing component, and the third energy-absorbing component are detachably connected through the four sets of locking strips 106. Figure 2 As shown, each of the four sets of clips 106 is fixedly provided with two L-shaped end plates 109, with the two L-shaped end plates 109 located at both ends of each set of clips 106, as follows. Figure 2 As shown, the first energy-absorbing chamber 102, the second energy-absorbing chamber 103, and the third energy-absorbing chamber 113 are all provided with vertical grooves 107. Several guide grooves 108 are provided on both sides of the vertical grooves 107. In the event of a collision, the guide grooves 108 guide the first energy-absorbing chamber 102, the second energy-absorbing chamber 103, and the third energy-absorbing chamber 113 to fold in a specific direction, achieving different levels of energy absorption. In the event of a smaller collision, the corresponding components will deform, causing the connecting screws at the adjacent third connecting plate 105 to deform or become blocked, preventing module replacement. Figure 3 As shown, this embodiment effectively avoids the problem of difficult removal at the splice due to deformation by setting the clip 106 on the side. The clip 106 is also provided with a special disassembly reserved plate, namely the L-shaped end plate 109. By using a tool to apply hammering force to the L-shaped end plate 109, the clip 106 can be easily disassembled and a new energy-absorbing component can be replaced.

[0023] like Figure 1 As shown, this embodiment also proposes a processing technology for a collision energy-absorbing box for new energy vehicles, specifically including a processing device 200 for processing the above-mentioned spliced ​​energy-absorbing box 100. The spliced ​​energy-absorbing box 100 is formed by splicing multiple components, and the processing device 200 completes the assembly of the above-mentioned spliced ​​energy-absorbing box 100.

[0024] like Figure 6 As shown, the processing device 200 includes a processing table 201, on which a splicing bracket 208 is provided. The splicing bracket 208 is used to place the first energy-absorbing component, the second energy-absorbing component, and the third energy-absorbing component, so that they can be spliced ​​together. The processing table 201 is also provided with a side fixing mechanism, which is used to grab the clips 106 on the splicing energy-absorbing box 100 and insert the limiting pins 112 on the clips 106 into the limiting holes to realize the detachable splicing between the first energy-absorbing component, the second energy-absorbing component, and the third energy-absorbing component. The processing table 201 is also provided with a two-end alignment mechanism, which is located at both ends of the splicing bracket 208. When the first energy-absorbing component, the second energy-absorbing component, and the third energy-absorbing component are placed on the splicing bracket 208, the first energy-absorbing component, the second energy-absorbing component, and the third energy-absorbing component are aligned by the two-end alignment mechanism. After alignment, the side fixing mechanism is used to install several clips 106.

[0025] like Figure 6 As shown, the side fixing mechanism includes two sets of conveyor belts 202, which are located on both sides of the splicing bracket 208. A clip 106 is placed on each conveyor belt 202, and the clip 106 is fed through the conveyor belts 202. The splicing bracket 208 is a symmetrically arranged L-shaped plate. Each L-shaped plate has a first limiting groove 210 and a second limiting groove 209. In use, the third connecting plate 105 on the first energy-absorbing component is pushed into the second limiting groove 209, and the third connecting plate 105 on the second energy-absorbing component is... Two third connecting plates 105 are pushed into the first limiting groove 210 and the second limiting groove 209 respectively, and the third connecting plate 105 on the third energy-absorbing component is pushed into the first limiting groove 210. At this time, the first energy-absorbing component, the second energy-absorbing component and the third energy-absorbing component can be aligned in sequence. The third connecting plates 105 at the splicing point correspond to each other. Then, the first energy-absorbing component, the second energy-absorbing component and the third energy-absorbing component can be aligned by the two-end alignment mechanism. Finally, the clip 106 is inserted into the corresponding position to realize the splicing of the three.

[0026] like Figure 6As shown, the side fixing mechanism includes a first mounting bracket 203, which is fixed to the surface of the processing table 201. A first mounting plate 204 is fixed on the first mounting bracket 203, and a bidirectional telescopic cylinder 205 is fixed on the first mounting plate 204. First side brackets 206 are fixed on both output ends of the bidirectional telescopic cylinder 205. Second side brackets 207 are rotatably mounted on the first side brackets 206 on both sides. The rotatable connection is driven by a motor. The second side brackets 207 have a U-shaped structure, and two adsorption plates 237 are provided on each of the second side brackets 207 on both sides. The two adsorption plates 237 are located on the second side brackets 201 respectively. At the U-shaped opening of 07, the distance between the two adsorption plates 237 on the same side is equal to the spacing of the clips 106 installed on the same side of the spliced ​​energy absorption box 100. The adsorption plate 237 is equipped with a negative pressure mechanism to achieve negative pressure attraction. In use, the adsorption plates 237 on both sides are used to adsorb the clips 106 on the two sets of conveyor belts 202 respectively. After adsorption and material removal are completed, the second side bracket 207 is rotated and the distance between the two side brackets 207 is adjusted in conjunction with the bidirectional telescopic cylinder 205 so that the clips 106 on the adsorption plate 237 are aligned with the installation position. The clips 106 are pressed onto the spliced ​​energy absorption box 100 by the adjustment of the bidirectional telescopic cylinder 205.

[0027] like Figure 11 As shown, the end-end alignment mechanism includes a sliding end plate 212, wherein the sliding method of the end plate 212 is as follows: Specifically, the end-end alignment mechanism also includes a second mounting plate 211 fixed on the table surface of the processing table 201. A moving strip 214 is fixedly mounted on the end plate 212 via a metal rod 213. A first rack is fixedly mounted on the moving strip 214. A first gear 215 is rotatably mounted on the second mounting plate 211. The first gear 215 meshes with the first rack. A first pulley 216 is coaxially mounted and fixed on the first gear 215, as shown below. Figure 8 As shown, a horizontal mounting plate 221 is fixedly installed below the table surface inside the processing table 201. A gearbox 223 is fixedly installed on one side of the horizontal mounting plate 221. The gearbox 223 has two output ends. One output end is connected to a first threaded rod 222, and the other output end is connected to a connecting shaft 219. Figure 11As shown, one end of the connecting shaft 219 is coaxially and fixedly provided with a second pulley 217. A first synchronous belt 218 is connected between the first pulley 216 and the second pulley 217. A drive source is provided in the gearbox 223. The drive source synchronously drives the first threaded rod 222 and the connecting shaft 219 to rotate. The connecting shaft 219 realizes the rotation of the first gear 215 through the first synchronous belt 218. The first gear 215 meshes with the first rack to realize the lateral movement of the end plate 212. In use, when the first energy-absorbing component, the second energy-absorbing component and the third energy-absorbing component are respectively inserted into the designated position of the splicing bracket 208, the end plate 212 is moved laterally to one end of the splicing bracket 208. At this time, the first energy-absorbing component, the second energy-absorbing component and the third energy-absorbing component are pushed forward. When the third connecting plate 105 on the first energy-absorbing component, the second energy-absorbing component and the third energy-absorbing component are in contact with the end plate 212, the alignment of the first energy-absorbing component, the second energy-absorbing component and the third energy-absorbing component can be realized.

[0028] This embodiment also includes an end pusher plate 228 to move the first energy-absorbing component, the second energy-absorbing component, and the third energy-absorbing component forward. Specifically, as shown in the example... Figure 10 As shown, the horizontal mounting plate 221 has a first threaded rod 222 and a first limiting rod 236 at both ends. The first threaded rod 222 is connected to the gearbox 223, and the gearbox 223 enables the rotation of the first threaded rod 222. The first limiting rod 236 is fixedly mounted on the horizontal mounting plate 221. A first base 224 is threaded onto the first threaded rod 222, and the first limiting rod 236 slides with the first base 224. Figure 8As shown, a sliding groove 225 is vertically arranged on the first base 224, and an end push plate 228 is slidably arranged on the sliding groove 225. Several first telescopic rods 227 are fixed between the end of the sliding groove 225 and the end push plate 228. The several first telescopic rods 227 are sleeved with first springs 226. The end push plate 228 is Z-shaped. Since the width of the first connecting plate 101 of the spliced ​​energy-absorbing box 100 is greater than that of the middle third connecting plate 105, the end push plate 228 is designed to be Z-shaped. This allows the upper part of the end push plate 228 to contact the middle several third connecting plates 105 during the pushing process, and pushes the several third connecting plates 105 forward until they are in contact with the end plate 212, thus realizing the first energy-absorbing component. The alignment of the second and third energy-absorbing components is achieved by the first threaded rod 222 moving the first base 224 up and down during use. The first threaded rod 222 and the connecting shaft 219 rotate synchronously, which further enables the synchronous movement of the first base 224 and the end plate 212. When the end plate 212 moves laterally to one end of the first, second, and third energy-absorbing components, the first base 224 drives its upper end push plate 228 to move upward until the height of the end push plate 228 is greater than the height of the uppermost first connecting plate 101 of the spliced ​​energy-absorbing box 100, ensuring that the end push plate 228 can simultaneously push the first, second, and third energy-absorbing components to move.

[0029] When the end push plate 228 moves upward to the specified height, it cannot perform the pushing function. Therefore, this embodiment also provides a separate lateral pushing mechanism for the end push plate 228 to push the end push plate 228. Specifically, a hollow groove is provided in the middle of the table surface of the processing table 201. A first telescopic cylinder 229 is fixedly installed in the hollow groove. A third mounting plate 230 is fixedly installed at the output end of the first telescopic cylinder 229. Connecting rods 231 are symmetrically provided on the third mounting plate 230, such as... Figure 9 As shown, baffles 233 are fixedly provided at the ends of the two connecting rods 231. The baffles 233 are perpendicular to the connecting rods 231, and bending plates 234 are rotatably provided on both baffles 233. Two ear plates 232 are fixedly provided on the end push plate 228. The two ear plates 232 are located above the first base 224. When the end push plate 228 moves upward to a specified height, the two ear plates 232 on the end push plate 228 are higher than the baffles 233. At this time, the connecting rod 231 moves laterally through the first telescopic cylinder 229. The baffles 233 on the connecting rod 231 move synchronously. During the movement, they will contact the two ear plates 232 on the end push plate 228 and pull the two ear plates 232 to move synchronously. Finally, the end push plate 228 moves laterally. The lateral movement of the end push plate 228 can push the first energy absorption component, the second energy absorption component, and the third energy absorption component, so that the first energy absorption component, the second energy absorption component, and the third energy absorption component are aligned.

[0030] After alignment, the side fixing mechanism is activated to insert several clips 106, ultimately assembling the spliced ​​energy-absorbing box 100. After assembly, the finished product needs to be ejected. At this time, the end plate 212 is retracted. During the retraction of the end plate 212, the end push plate 228 moves downwards with the first base 224 until the end push plate 228 is completely retracted below the surface of the processing table 201. The first telescopic rod 227 and the first spring 226 reset the end push plate 228. Then, continuing to move the connecting rod 231 laterally will eject the assembled finished product as a whole. Specifically, as follows... Figure 7 As shown, several second springs 235 are connected between the bending plate 234 and the baffle 233. When the end push plate 228 retracts downward, the bending plate 234 moves with the movement of the connecting rod 231. The height of the bending plate 234 is greater than the height of the first connecting plate 101 at the bottom of the spliced ​​energy-absorbing box 100. Therefore, the bending plate 234 can continue to push the spliced ​​energy-absorbing box 100 forward. The other end of the processing table 201 is fixedly provided with a slide table 220. The spliced ​​energy-absorbing box 100 slides down the slide table 220 to collect.

[0031] During use, the first, second, and third energy-absorbing components are fed manually or mechanically. Mechanical feeding requires pushing the first, second, and third energy-absorbing components horizontally onto the first limiting groove 210 and the second limiting groove 209. Directly placing the end pusher 228 at the front would obstruct the pushing of the first, second, and third energy-absorbing components and also result in an excessively large equipment footprint. Therefore, this embodiment incorporates a hidden end pusher 228, which is concealed inside the lower part of the equipment when not in use, thus reducing the equipment's size. When the first, second, and third energy-absorbing components are fed horizontally, the bending plate 234, being higher than the bottom of the spliced ​​energy-absorbing box 100, will obstruct the horizontal pushing of the first energy-absorbing component. Therefore, if... Figure 12 and Figure 13 As shown, the bending angle of the bending plate 234 is less than 90 degrees. When the first energy-absorbing component is pushed in horizontally, the first energy-absorbing component will contact the bending plate 234 and squeeze the bending plate 234.
