[0003] For example, unlike the traditional fuel vehicle engine and transmission which occupy most of the front compartment space, the front compartment of a pure electric vehicle only has a motor and an electronic control system, and the size is much smaller than that of a traditional fuel power assembly.

However, for the front compartment area of the vehicle, it is an important area for collision safety, and in the related technology, it is difficult to ensure the crash performance of the front compartment on the basis of meeting the storage space. In addition, in other structures of the automobile, the crash performance is also difficult to meet, for example, for the bumper and ventilation cover plate of the vehicle, when the vehicle is hit, these structures are also easy to cause impact on other important parts of the vehicle due to insufficient collapse space, and it is also difficult to ensure the safety of pedestrians.

[0025] According to a second aspect of the present application, a front compartment assembly is provided, comprising the energy-absorbing structure as described above.
[0026] Optionally, the front compartment assembly further comprises:
[0027] a front compartment cover connected to the energy-absorbing structure.
[0028] The front cabin storage box is provided with a sealing element abutting against the energy-absorbing structure.

[0047] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative effort should fall within the protection scope of the present application.
[0048] According to a first aspect of the present application, the present application provides an energy absorption structure 100, please refer to Figure 1-4 , Figure 1 The cross-sectional schematic view of the energy absorption structure 100 provided by an embodiment of the present application in an unfolded state is shown in Figure 2 The cross-sectional schematic view of the energy absorption structure 100 in the embodiment in a collapsed and folded state under stress is shown in Figure 3 The cross-sectional schematic view of the energy absorption structure provided by another embodiment of the present application in an unfolded state is shown in Figure 4 The cross-sectional schematic view of the energy absorption structure 100 in the embodiment in a collapsed and folded state under stress is shown in
[0049] The energy absorption structure 100 provided by the present application can be specifically applied to a vehicle, including a first support 101, a second support 102 and a deformation member 103. The first support 101 and the second support 102 serve as a support, for example, a support when cooperating with other structures for connection, contact, etc. The two ends of the deformation member 103 are connected to the first support 101 and the second support 102, respectively. The energy absorption structure 100 is used to make the deformation member 103 and the second support 102 move when stressed, so as to collapse the energy absorption structure 100.
[0050] The stress of the energy absorption structure 100 in the present application mainly refers to the overall impact force, for example, the front impact force and the rear support extrusion force when applied to a vehicle.
[0051] Referring to Figure 3 and Figure 4 , in some embodiments of the present application, the energy absorption structure 100 adopts a three-section structure, the first support 101, the deformation member 103 and the second support 102 are connected in sequence, so that in the unstressed state, part of the cross section is strip-shaped.
[0052] Referring to Figure 1 and Figure 2 , in some other embodiments of the present application, the second support 102 has a "U" shaped cross section, and the two sides thereof are connected in sequence with the deformation member 103 and the first support 101, respectively, so that in the unstressed state, part of the cross section is "U" shaped.
[0053] In the state of no force, the size of the energy absorption structure 100 along the collapse direction is relatively large. When the energy absorption structure 100 is installed in a specific position, for example, installed in the front cabin of a vehicle, if a collision occurs during the vehicle running, the whole energy absorption structure 100 is forced, at this time, based on the force conduction, the deformation piece 103 and the second support piece 102 are active, and then the energy absorption structure 100 is collapsed to realize the size reduction of the collapse process. Wherein, the deformation piece 103 and the second support piece 102 can be active to make the energy absorption structure 100 collapse to realize the size reduction, so as to meet different collision scenarios. In some cases, the deformation piece 103 deforms and the second support piece 102 slightly moves to realize the collapse of small size, or in some cases, the deformation piece 103 deforms and the second support piece 102 moves greatly to realize the collapse of large size, so as to meet the five-star collision requirement. For example, the deformation piece 103 and the second support piece 102 are forced to move to the position shown in Figure 2 or Figure 4 At this time, the whole size of the energy absorption structure 100 is collapsed to be smaller, realizing the collapse of large size, and then the safety collision demand can be met.
[0054] Based on this, the present application can realize the collapse of large size, and then facilitate to meet the safety collision demand of large size, such as in Figure 1-4 The cross sections of the first support piece 101, the deformation piece 103 and the second support piece 102 are the same in the same direction, and the distance is L. The whole size is 3L, and finally, after collapse, the whole size is L. In this way, the effective collapse size can be greatly increased, and the collision energy can be reduced to a safe level in two collapse strokes, so as to meet the five-star collision requirement. At the same time, the structure of the present application is simple, and after collapse, due to the setting of the deformation piece 103, the collapsed part can be manually restored to the unfolded state for repeated use, so it also has high maintenance economy.
[0055] Compared with the scheme of using the "8" type sealing bubble tube to collapse by itself deformation in the prior art, the energy absorption structure of the present application can deform and collapse, and the structure part can move within a certain range to realize the collapse of large size, further improving the collision performance.
[0056] In addition, in the related art, the cavity distance of the inner and outer panels of the hood is increased to meet the crash performance while being able to complete sealing. However, the hood is affected by the arrangement of peripheral components, which causes the crash area to be unable to be effectively stamped and formed, so that the cavity distance is difficult to reach the preset target value. Moreover, increasing the cavity distance of the hood causes the perception of the thickness of the hood to be poor and the weight to increase, and therefore, the distance between the front compartment hood and the front compartment storage box is often greatly increased to meet the crash performance, which causes the front compartment storage box to complete sealing by itself, for example, by increasing the front compartment storage box cover to achieve sealing alone, which increases the weight and cost of the vehicle, and the user also needs to additionally open the front compartment storage box cover when taking the items in the front compartment storage box, which is poor in human-machine convenience.
[0057] The energy-absorbing structure 100 is improved in the present application, and the whole can be made of a material related to improving the sealing effect, so as to ensure the sealing performance. At this time, when applicable to some structural parts, the sealing effect of the whole structure can be ensured, for example, when arranged around the edge of the opening of the front compartment storage box, the sealing of the front compartment storage box is achieved. At this time, the storage box cover plate does not need to be arranged alone, thereby reducing the structure weight and cost, and opening the front compartment cover plate opens the front compartment storage box, improving the convenience of taking and placing items. Compared with the scheme of increasing the front compartment storage box cover plate and increasing the inner cavity space of the front compartment hood in the prior art, the energy-absorbing structure in the present application has a relatively large size along the collapse direction to meet the crash performance, which raises the space between the opening of the front compartment storage box and the front compartment hood. This part of the space can still be used to accommodate items, so as to avoid the space of the front compartment storage box being compressed, ensure the storage space, and improve the user experience.
[0058] Referring to Figure 1-4 As shown in FIG. 1, the cross-sectional shape of the first support 101, the deformation member 103, and the second support 102 is shown, and the specific structure of the whole can be set according to the specific need to seal the device or structure and its shape. For example, for some edges that need to be sealed, it can be set as a long strip, and for some openings or slots that need to be sealed, such as the opening of the front compartment storage box 400, it can be set as a ring structure that can surround the opening.
[0059] In some embodiments of the present application, at least part of the deformation member 103 and the second support 102 is used to move to at least one side of the second direction of the first support 101 along the first direction when subjected to force, wherein the first direction and the second direction form an angle.
[0060] Referring to Figure 2 and Figure 4As shown in the drawings, in some embodiments of the present application, the first direction refers to the y direction in the drawings, and the second direction refers to the x direction in the drawings. In this embodiment, the first direction y is perpendicular to the second direction x, the first support 101 is in a strip shape, has a side wall, and the second direction is the direction in which the side wall of the first support 101 points. Thus, when the deformation member 103 and the second support 102 are stressed, they move towards the direction in which the side wall of the first support 101 points. Thus, the deformation member 103 and the second support 102 bend towards one side of the first support 101 and finally overlap the first support 101. Based on the specific sizes of the deformation member 103, the second support 102 and the first support 101, the deformation member 103 and the second support 102 can partially overlap the first support 101 or completely overlap the first support 101. In this embodiment, the deformation member 103 and the second support 102 move to a position completely overlapping the first support 101, so as to form a large size collapse and further improve the safety crash performance. Figure 2 In this embodiment, the deformation member 103 and the first support 101 include two parts located on both sides of the second support 102. At this time, the deformation member 103 and the second support 102 move upwards towards the first support 101, so as to realize the collapse of the energy absorption structure. When moving to between the two first supports 101, i.e., the second support 102 and the deformation member 103 move to the left side of one first support 101, it is equivalent to being located on the right side of the other first support 101.
[0061] In other embodiments, the included angle between the first direction and the second direction can be an obtuse angle or an acute angle. At this time, as x is also a horizontal second direction, the deformation member 103 and the second support 102 can tilt upwards along the first direction y and finally move to at least one side of the first support 101 in the second direction x.
[0062] Referring to Figure 1 and Figure 2 As shown in the drawings, when the energy absorption structure 100 is not collapsed, the deformation member 103 includes at least one curved section, so as to facilitate controlling the direction of the deformation member 103 in the deformation process when the energy absorption structure is stressed and collapses as a whole. In this specific embodiment, the arc surface formed by the bending of the deformation member 103 points between the two first supports 101, so that the deformation member 103 and the second support 102 move towards the first direction as a whole, more specifically, move towards between the first supports 101, so that the collapse caused by the collision is more stable.
[0063] In some embodiments of the present application, when the energy absorption structure 100 is not collapsed, the included angle between the first support 101 and the deformation member 103 is an obtuse angle. In this way, the direction of the movement of the deformation member 103 and the second support 102 can also be controlled, so that the collapse caused by the collision is more stable.
[0064] In some embodiments of the present application, the second support 102 comprises a support bottom wall 112 and support side walls 122 respectively arranged at both ends of the support bottom wall 112 in the second direction, one end of the support side wall 122 is connected with the support bottom wall 112, and the other end of the support side wall 122 is connected with the deformation member 103.
[0065] Referring to FIGS. 1 and 2, Figure 1 and Figure 2 It can be seen that the second support 102 has a "U" shape in cross section, which has support side walls 122 at both ends of the support bottom wall 112 in the second direction, i.e. Figure 2 and Figure 4 x direction, and the support bottom wall 112 is partially used for connection or adhesion with other structures to achieve support. The two support side walls 122 are respectively connected with a deformation member 103, and correspondingly, the other end of the deformation member 103 is connected with a first support 101, so that the whole or part of the energy absorption structure 100 presents a "U" shape and forms an inner cavity. At this time, on the one hand, the structure of the "U" shape as a whole can better have the compression resistance performance, improve the support effect, and enable the energy absorption structure 100 to be more stably installed in cooperation with other structures, and on the other hand, when the energy absorption structure is stressed, the deformation member 103 and the second support 102 can collapse towards the inner cavity, so as to ensure that the collapsing process is more stably achieved, thereby better meeting the collision demand.
[0066] In some embodiments of the present application, the distance between the two first supports 101 located at both sides of the support bottom wall 112 is greater than the cross-sectional length of the support bottom wall 112.
[0067] Referring to FIGS. 1 and 2, Figure 2 It can be seen that in these embodiments, the cross-sectional length of the support bottom wall 112 is the distance M, and the distance between the two first supports 101 located at both sides of the support bottom wall 112 is the distance N in the figure. By limiting the size, it can be ensured to a certain extent that the deformation member 103 and the second support 102 are located between the two first supports 101 after the energy absorption structure 100 collapses, so as to ensure that the collapsing process is more stably achieved, thereby better meeting the collision demand.
[0068] In some embodiments of the present application, the energy absorption structure 100 further comprises a first cooperation installation part 104, and the first cooperation installation part 104 is connected with the first support 101.
[0069] Referring to FIGS. 1 and 2, Figure 1 and Figure 2As shown, in these embodiments, for the convenience of overall installation of the energy-absorbing structure 100, the energy-absorbing structure 100 can include a first matching mounting part 104, which can be a buckle and slot piece, a bolt connecting piece, etc. In this embodiment, the first matching mounting part 104 is a plate body structure with a clamping hole, which is connected with the first support part 101. Thus, the cross section of the energy-absorbing structure 100 is similar to a "j" character. At this time, the overall structure can better have a collapse performance and improve the supporting effect. The buckle 200 is used to form a detachable connection with other structures, so as to facilitate installation and disassembly. For example, referring to Figure 5 and Figure 6 As shown, the inner panel 302 of the front compartment hood 300 of the vehicle is detachably connected with the buckle 200.
[0070] In some embodiments of the present application, the energy-absorbing structure 100 is formed by integrally injection molding of various materials. In this embodiment, the energy-absorbing structure 100 can be obtained by double-color integrally injection molding. The first support part 101 and the second support part 102 can be made of hard plastic, and the deformation part 103 is made of plastic or rubber with a certain softness. Specifically, the second support part 102 and the first support part 101 can be obtained by injection molding of hard PP (Polypropylene, polypropylene material), and the deformation part 103 can be obtained by injection molding of soft TPV (Thermoplastic Vulcanizate, thermoplastic vulcanized rubber) material. Finally, the first support part 101, the second support part 102 and the deformation part 103 have different properties to achieve better deformation and supporting effect.
[0071] In some embodiments of the present application, the deformation force value of the first support part 101 and the second support part 102 is greater than the deformation force value of the deformation part.
[0072] In this embodiment, the deformation force value of the first support part 101 and the second support part 102 is greater than the deformation force value of the deformation part 103, so as to ensure that the deformation part 103 deforms to drive the second support part 102 to move when being impacted, and the first support part 101 and the second support part 102 are more difficult to deform to ensure the overall supporting performance. Based on this structural composition, the energy-absorbing structure 100 is also not easy to be damaged, and it is convenient to recover even after a large deformation.
[0073] In some embodiments of the present application, the deformation part 103 includes a structure made of soft material. Thus, the deformation and recovery of the overall energy-absorbing structure are facilitated by the soft material. In other embodiments, the deformation part 103 can also be composed of other composite material structures or realized by a combination of multiple structures.
[0074] In some embodiments of the present application, the first support 101 and the second support 102 comprise structures made of hard material, so that the first support 101 and the second support 102 are made of hard material to improve the support effect of the energy-absorbing structure 100 as a whole.
[0075] In some embodiments of the present application, the material hardness of the first support 101 and the second support 102 is greater than the material hardness of the deformation member 103, so that the first support 101 and the second support 102 are made of material with greater overall hardness to achieve better support effect.
[0076] In some embodiments of the present application, the material hardness of the first support 101 and the second support 102 is greater than the material hardness of the deformation member 103, so that the first support 101 and the second support 102 are made of material with greater overall hardness to achieve better support effect.
[0077] In some embodiments of the present application, the material hardness of the first support 101 and the second support 102 is greater than the material hardness of the deformation member 103, so that the first support 101 and the second support 102 are made of material with greater overall hardness to achieve better support effect.
[0078] In some embodiments of the present application, the material hardness of the first support 101 and the second support 102 is greater than the material hardness of the deformation member 103, so that the first support 101 and the second support 102 are made of material with greater overall hardness to achieve better support effect.
[0079] In some embodiments of the present application, the second support 102 can be used to abut against the sealing member 105, and the deformation force value of the sealing member 105 is less than the deformation force value of the deformation member 103.
[0080] Referring to Figure 5 and Figure 6As shown, in the embodiment, the sealing member 105 is arranged to cooperate with the first support member 101, the second support member 102 and the deformation member 103 to achieve sealing, wherein the deformation force value of the sealing member 105 is smaller than the deformation force value of the deformation member, so that when the energy absorption structure 100 is installed, the sealing member 105 can be deformed first to abut against the surface of the second support member 102 to form better sealing, and the deformation member 103 will only appear large size deformation when subjected to a larger impact force, so as to meet the buffering requirements in the non-collision working condition and the collision working condition respectively. For example, when installed in a vehicle, the deformation of the sealing member 105 plays a certain shock-absorbing role to protect the vehicle structure, and only when subjected to a larger impact force, the deformation member 103 will collapse and deform with the second support member 102 to meet the large size collapse collision requirement.
[0081] The deformation force value can be determined by the selection of the material. For example, the collapse process of the sealing member 105 is simulated to obtain a simulated deformation force value. The deformation force value of the sealing member 105 is set to 6-8 N / 100 mm, and the hardness of the deformation member 103 is adjusted to the required deformation force value, so that the deformation force value obtained in the simulation is finally 50 N / 100 mm. Due to the large difference between the two values, it is ensured that the deformation member 103 and the second support member 102 will only collapse when subjected to a larger impact force.
[0082] Referring to Figure 5 and Figure 6 As shown, in some embodiments of the present application, the sealing member 105 includes a sealing strip 115, and the side wall of the sealing strip 115 is used to abut against the second support member 102, so that the sealing strip 115 is tightly attached to the second support member 102 to achieve better sealing effect.
[0083] Referring to Figure 5 and Figure 6 As shown, the sealing strip 115 includes a foamed tube 115a, and the side wall of the foamed tube 115a is used to abut against the second support member 102.
[0084] In some embodiments of the present application, the sealing strip 115 is specifically selected to be a hollow foamed tube 115a, so that the foamed tube 115a is tightly attached to the second support member 102 to ensure better sealing effect. Alternatively, the foamed tube 115a can be made of EPDM (Ethylene-Propylene-Diene-Monomer) rubber material by extrusion process.
[0085] Referring to Figure 5 and Figure 6As shown, the sealing member 105 further comprises a second matching mounting portion 125 connected with the sealing strip 115.
[0086] In some embodiments of the present application, the sealing member 105 further has a second matching mounting portion 125, which can be a clamping structure, a bolt connection structure, etc. to facilitate dismounting and mounting. In a specific embodiment, the second matching mounting portion 125 comprises a clamping structure with a metal clamping spring 125a embedded therein, one end of the clamping structure being connected with the sealing strip 115, specifically with the foamed pipe 115a, and the other end being used for matching connection with other clamping matching members, for example, dismountable connection with the front compartment storage box 400 in the front compartment of the vehicle, so as to facilitate installation and fixation of the sealing member 105 and the whole energy-absorbing structure. Through the clamping structure form of the embedded metal clamping spring 125a, the clamping structure facilitates dismounting and installation, and facilitates support and shock-absorbing and buffering effects of the whole structure.
[0087] The energy-absorbing structure 100 in the present application can be widely applied to positions and regions of the whole vehicle that need energy absorption and buffering, which are not limited herein.
[0088] According to a second aspect of the present application, a front compartment assembly is provided, comprising the energy-absorbing structure 100 as described above. The front compartment assembly of the embodiments of the present application has the same or similar technical effects as the energy-absorbing structure 100 described above, and will not be described herein again.
[0089] In some embodiments of the present application, the front compartment assembly further comprises a front compartment cover 300 and a front compartment storage box 400, the front compartment cover 300 being connected with the energy-absorbing structure 100, and the front compartment storage box 400 being provided with the sealing member 105, and the sealing member 105 being in abutment with the energy-absorbing structure 100.
[0090] Referring to Figure 5 and Figure 6 As shown, the front compartment cover 300 specifically comprises a front compartment cover outer plate 301 and a front compartment cover inner plate 302 connected with each other, and the front compartment cover inner plate 302 is connected with the first matching mounting portion 104 of the energy-absorbing structure 100 through the buckle 200, so as to facilitate installation and dismounting of the energy-absorbing structure 100, and the opening outer edge of the front compartment storage box 400 is connected with the second matching mounting portion 125 of the sealing member 105 through the clamping member, so as to facilitate installation and fixation and dismounting of the sealing member 105.
[0091] In some embodiments of the present application, the sealing member 105 is arranged around the opening edge of the front cabin storage box 400. Thus, the first support member 101, the second support member 102, the deformation member 103 and the sealing member 105 cooperate to achieve sealing around the front cabin storage box 400 in the case of collision energy absorption and buffering, thereby ensuring that the front cabin storage box 400 has certain dustproof and waterproof performance, and without the need to set a front cabin storage box cover plate. The deformation force value of the sealing member 105 is less than the deformation force value of the deformation member 103, to ensure the installation support performance of the overall structure and the shock absorption performance in normal working conditions. In the case of collision, the sealing member 105 deforms first, the deformation member 103 deforms and generates a larger size collapse deformation with the second support member 102, thereby meeting the safety collision requirements. Compared with the deformation collapse achieved by increasing the width of the sealing mechanism, the above energy absorption structure 100 is used to achieve sealing while meeting the crash performance, and can greatly reduce the weight and production cost of the structure. Referring to Figure 7 As shown in FIG. 3, which is a partial structure schematic diagram of a vehicle applying the above front cabin assembly when the vehicle is not subjected to collision, at this time the sealing member 105 abuts against the second support member 102, and the energy absorption structure 100 is in an extended state. Figure 8 As shown in FIG. 4, which is a partial structure schematic diagram of a vehicle applying the above front cabin assembly when the vehicle is subjected to collision, at this time the energy absorption structure 100 is deformed under pressure, and the second support member 102 and the deformation member 103 are both moved to between the two first support members 101, so that the energy absorption structure is in a folded state.
[0092] The material of the front cabin storage box 400 can be PP+GF (Glass Fiber, glass fiber reinforced plastic), which is formed by using an injection molding process. The front cabin cover 300 can be obtained by a sheet metal stamping process, and can be formed of aluminum or steel sheet metal.
[0093] According to a third aspect of the present application, an energy absorption structure 100 is provided.
[0094] For example, the bumper of a vehicle, in order to ensure effective heat dissipation of the intake air, a radiator deflector is added between the front bumper and the front compartment radiator to seal, so as to guide the airflow to the radiator to improve the heat dissipation efficiency. The current industry mainstream radiator deflector structure is strong, when low-speed collision occurs, the front bumper collision energy will be directly transmitted to the radiator through the radiator deflector, which will usually have two adverse factors: 1. With the radiator deflector, the entire transmission path structure is too strong, which reduces the passive safety score and cannot meet the five-star collision requirements; 2. The collision energy directly transmitted to the radiator will cause the radiator to break and leak coolant, causing the engine to overheat and alarm, and ultimately causing the vehicle power system to malfunction. By applying the above energy-absorbing structure 100 to the bumper, in addition to achieving the technical effects of the energy-absorbing structure 100, it can also solve the above-mentioned problems to a certain extent without affecting the intake efficiency.
[0095] According to a fourth aspect of the present application, a ventilation cover plate is provided, comprising the energy-absorbing structure as described above.
[0096] The energy-absorbing structure of the embodiments of the present application can be specifically applied to the ventilation cover plate of a vehicle. By providing the energy-absorbing structure on the ventilation cover plate body and other structural parts of the vehicle, when impacted, the large size of the energy-absorbing structure collapses to achieve better crash performance, while ensuring that the ventilation cover plate or the impact object cannot damage other important structures inside the vehicle. In addition, the ventilation cover plate also has the same or similar technical effects as the above-mentioned energy-absorbing structure, which will not be described here.
[0097] According to a fifth aspect of the present application, a vehicle is provided, comprising at least one of the energy-absorbing structure, the front compartment assembly, the bumper and the ventilation cover plate as described above.
[0098] The vehicle of the embodiments of the present application has the same or similar technical effects as the above-mentioned energy-absorbing structure, which will not be described here.
[0099] The vehicle can be a fuel automobile, a plug-in hybrid electric vehicle or a new energy vehicle, etc., and the present disclosure does not make specific limitations thereto.
