[0002] Vehicles are an indispensable means of transportation for people to travel, and their safety performance is very important. In order to improve the safety performance of the vehicle, the front end of the vehicle is equipped with a front collision beam assembly structure. The front collision beam assembly is an important safety device that can absorb and mitigate external impact to protect the vehicle body structure and the people inside the vehicle.

[0049] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the specific technical scheme of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0050] In the embodiments of the present application, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present application, unless otherwise specified, "multiple" means two or more.

[0051] In addition, in the embodiments of the present application, directional terms such as "up", "down", "left" and "right" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they may change accordingly according to the changes in the orientation of the components in the drawings.

[0052] In the embodiments of the present application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0053] In the embodiments of the present application, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0054] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0055] The embodiment of the present application provides a front collision beam assembly, which is located at the front end of the vehicle and can be used to absorb and mitigate external impact forces to protect the vehicle body structure and the occupants. On the one hand, when the vehicle collides at a low speed, the energy is effectively absorbed by the energy absorption box of the front collision beam assembly through collapse and deformation, thereby protecting the longitudinal beam from damage and reducing maintenance costs. On the other hand, when the vehicle collides at a high speed, the energy is effectively transferred to the longitudinal beam through the front collision beam assembly, making the longitudinal beam the main force-bearing object, thereby reducing the damage to the occupants.

[0056] The front collision beam assembly is applied to a vehicle. It should be noted that the vehicle in this application may refer to a large car, a small car, a special-purpose car, etc. For example, according to the vehicle type, the vehicle in this application may be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV) or other vehicle types. For a vehicle, wheels, a power source, and a transmission system arranged between the wheels and the power source are generally provided. The transmission system can transmit the power provided by the power source to the wheels, so that the wheels rotate, thereby driving the vehicle to travel.

[0057] It should be noted that in the embodiments of the present application, the type of the power source of the vehicle is not limited. For example, for a fuel vehicle, the power source may refer to a fuel engine such as a gasoline engine or a diesel engine; for an electric vehicle, the power source may refer to an electric motor; for a hybrid vehicle, the power source may refer to an engine or an electric motor; for a vehicle powered by other means, the power source may refer to a device that generates power.

[0058] The vehicle is usually equipped with a front hood lock and a front frame. The front hood lock is set on the front frame. The front hood lock and the front frame are both located at the front end of the vehicle. The front hood lock can close or open the front hood. The front frame is used to install structures such as a radiator. In the related art, the area corresponding to the front hood lock and the front frame is spaced apart from the front collision beam assembly below. When the front hood is closed, the front hood exerts a downward force on the front hood lock and the gravity of the radiator and the front frame itself, which easily causes deformation in the connection area between the front hood lock and the front frame.

[0059] Based on the above technical problems, the applicant has improved the structure of the existing front collision beam assembly. In the front collision beam assembly provided by the embodiment of the present application, the front cover lock can be connected to the beam body through the front cover lock connection assembly, and the front end frame and the beam body can be connected through the front end module connection assembly. Therefore, the front cover lock, the front end frame and the beam body can be connected to form an integral structure. When the front cover is closed, the front cover applies a downward force to the front cover lock, and the beam body located below the front cover lock can provide a supporting force for the front cover lock to improve the structural strength of the connection area between the front cover lock and the front end frame, and reduce the possibility of deformation of the connection area between the front cover lock and the front end frame. In addition, the force applied by the front cover to the front cover lock can be transmitted to the beam body through the front cover lock connection assembly, and then transmitted to the energy absorption box and the longitudinal beam through the beam body. The energy absorption box or the longitudinal beam can absorb the force applied by the front cover to the front cover lock, so as to more effectively improve the stiffness, strength and ultimate tensile force of the connection area between the front cover lock and the front end frame.

[0060] The front collision beam assembly 100 and the vehicle provided by the present application will be described below with reference to the accompanying drawings and in combination with specific embodiments.

[0061] Figure 1 This is a structural schematic diagram of a front collision beam assembly 100 provided in the present application being connected to a front hood lock 200 and a front end frame 300. Figure 2 for Figure 1 Schematic diagram of the local cross-sectional structure along the AA direction. Figure 3 This is a schematic diagram of the front cover lock connection assembly 120 provided in the present application in a front view structure in an application state. The front view structure schematic diagram refers to a schematic diagram from the front side of the vehicle to the rear side.

[0062] See also Figures 1 to 3 As shown, the front impact beam assembly 100 of the embodiment of the present application is connected with the front cover lock 200 and the front end frame 300. The front impact beam assembly 100 includes a beam body 110, a front cover lock connection assembly 120 and a front end module connection group 130.

[0063] The cross beam body 110 is located below the front cover lock 200. The front cover lock connecting assembly 120 includes a first connecting portion 120a and a second connecting portion 120b. The first connecting portion 120a can be connected to the cross beam body 110. The second connecting portion 120b can be connected to the front cover lock 200. The first connecting portion 120a and the second connecting portion 120b are connected to connect the cross beam body 110 and the front cover lock 200. The front end module connecting group 130 can be used to connect the cross beam body 110 and the front end frame 300.

[0064] The front hood lock connection assembly 120 of the embodiment of the present application can connect the front hood lock 200 and the cross beam body 110 into a whole, so that the cross beam body 110 can provide support for the front hood lock 200 when the front hood is closed. The front module connection group 130 can connect the front frame 300 and the cross beam body 110 into a whole, and the front hood lock 200 can be installed on the front frame 300. Therefore, the front hood lock 200, the front frame 300 and the cross beam body 110 can be connected to each other to form a whole, so as to improve the overall rigidity, strength and ultimate tensile force of the vehicle front end structure.

[0065] When the front hood is closed, the force exerted by the front hood on the front hood lock 200, the gravity of the front end frame 300 and the radiator on the front end frame 300 can be transmitted to the crossbeam body 110 through the front hood lock connection assembly 120 and the front end module connection assembly 130, and then transmitted to the energy absorption box 140 and the longitudinal beam through the crossbeam body 110, thereby alleviating the force exerted on the front hood lock area and reducing the possibility of deformation or even damage to the front hood lock area.

[0066] The front cover lock area may refer to a connection area between the front cover lock 200 and the front end frame 300 and a connection area between the front cover lock 200 and the cross beam body 110 .

[0067] In some possible implementations, see Figures 1 to 3 As shown, the front cover lock connection assembly 120 of the embodiment of the present application may include a first connection member 121 and a second connection member 122. The first connection portion 120a may be located at the first connection member 121. The second connection portion 120b may be located at the second connection member 122. The first connection member 121 and the second connection member 122 are detachably connected.

[0068] In the embodiment of the present application, the first connection part 120a of the first connection member 121 can be used to connect with the cross beam body 110. The second connection part 120b of the second connection member 122 can be used to connect with the front cover lock 200. The first connection member 121 is connected to the second connection member 122. The downward force applied to the front cover lock 200 by the front cover can be transmitted to the cross beam body 110 through the second connection member 122 and the first connection member 121. The force can be transmitted to the two ends of the cross beam body 110, and to the energy absorption box 140 and the longitudinal beam to absorb the force borne by the front cover lock 200, and reduce the possibility of deformation or damage in the front cover lock area.

[0069] In some examples, the first connection portion 120a of the first connection member 121 can be welded to the cross beam body 110. The second connection portion 120b of the second connection member 122 can be detachably connected to the front cover lock 200. The first connection member 121 and the second connection member 122 can be detachably connected to facilitate the fixed connection between the front cover lock 200 and the cross beam body 110.

[0070] In some possible implementations, see Figure 2 and Figure 3 As shown, the first connecting member 121 of the embodiment of the present application may also include a first vertical plate 1211. The first vertical plate 1211 is connected to the first connecting portion 120a. The first vertical plate 1211 may be provided with a first connecting hole. The second connecting member 122 may also include a second vertical plate 1221. The second vertical plate 1221 is connected to the second connecting portion 120b. The second vertical plate 1221 may be provided with a second connecting hole corresponding to the first connecting hole.

[0071] In the embodiment of the present application, the first connecting member 121 and the second connecting member 122 may be connected by the first vertical plate 1211 and the second vertical plate 1221. The first vertical plate 1211 and the second vertical plate 1221 may have a supporting function to provide an upward supporting force for the front cover lock 200 when the front cover acts on the front cover lock 200.

[0072] In some possible implementations, see Figure 2 and Figure 3 As shown, along the traveling direction Y of the vehicle, the second vertical plate 1221 of the embodiment of the present application can be located on the side of the first vertical plate 1211 facing the cross beam body 110. The front cover lock connection assembly 120 can also include a connection column 123. The connection column 123 can be passed through the first connection hole of the first vertical plate 1211 and the second connection hole of the second vertical plate 1221 to connect the first connection member 121 and the second connection member 122.

[0073] In the embodiment of the present application, the second vertical plate 1221 can be connected to the surface of the first vertical plate 1211 facing the cross beam body 110. The second vertical plate 1221 can constrain the first vertical plate 1211 to move in the direction of the vehicle moving forward, and the first vertical plate 1211 can constrain the second vertical plate 1221 to move in the direction of the vehicle moving backward. Therefore, the connection reliability of the first connecting member 121 and the second connecting member 122 can be improved by the mutual constraint of the first vertical plate 1211 and the second vertical plate 1221.

[0074] In some examples, the connection column 123 may be a locking bolt which may be sequentially passed through the second connection hole of the second vertical plate 1221 and the first connection hole of the first vertical plate 1211 from one side of the second vertical plate 1221 and locked with the front cover lock 200 .

[0075] In some examples, the first connecting member 121 may further include a first transverse plate 1212. The first connecting portion 120a is located on the first transverse plate 1212. The first transverse plate 1212 is connected to the first vertical plate 1211.

[0076] Exemplarily, the first transverse plate 1212 and the first vertical plate 1211 may have an angle therebetween. For example, the first transverse plate 1212 and the first vertical plate 1211 may be perpendicular to each other. The longitudinal section of the first connecting member 121 may be "L" shaped, and the longitudinal section of the first connecting member 121 is parallel to the vehicle travel direction Y.

[0077] In some examples, the second connecting member 122 may further include an abutment plate 1222. The second connecting portion 120b is located on the abutment plate 1222. A side surface of the abutment plate 1222 may be in contact with the front cover lock 200. The second vertical plate 1221 is connected to the abutment plate 1222. The abutment plate 1222 and the front cover lock 200 may be detachably connected via a locking member.

[0078] Exemplarily, the second connector 122 may further include an adapter plate 1223. The adapter plate 1223 may connect the second vertical plate 1221 and the abutment plate 1222. For example, the longitudinal section of the second connector 122 may be "Z" shaped, and the longitudinal section of the second connector 122 is parallel to the vehicle travel direction Y.

[0079] Figure 4 yes Figure 1 Schematic diagram of the local cross-sectional structure along the BB direction.

[0080] In some possible implementations, see Figure 1 and Figure 4 As shown, the front module connection group 130 of the embodiment of the present application may include a front module support 131. The front module support 131 may include a third connection portion 131a and a third vertical plate 1311. The third connection portion 131a is connected to the cross beam body 110. The third vertical plate 1311 is connected to the front frame 300.

[0081] When the front hood acts downward on the front hood lock 200, the front end frame 300 is also subjected to a downward force. Therefore, the front end module of the embodiment of the present application can transfer the force applied to the front end frame 300 to the cross beam body 110. The force can be transferred to both ends of the cross beam body 110 to be absorbed by the energy absorption box 140 and the longitudinal beam, so that the front end module support member 131 can be used to improve the rigidity, strength and ultimate tensile force of the front hood lock area.

[0082] In the embodiment of the present application, the third vertical plate 1311 can provide auxiliary support for the front-end module.

[0083] In some examples, the front module support 131 may further include a second transverse plate 1312. The third connection portion 131a may be located on the second transverse plate 1312. The second transverse plate 1312 and the third vertical plate 1311 may be connected.

[0084] Exemplarily, the second transverse plate 1312 and the third vertical plate 1311 may have an angle. For example, the second transverse plate 1312 and the third vertical plate 1311 may be perpendicular to each other.

[0085] In some possible implementations, see Figure 1 and Figure 3 As shown, the number of the front module support members 131 in the embodiment of the present application can be two. Along the length direction X of the cross beam body 110, the two front module support members 131 can be respectively located on both sides of the front cover lock connection assembly 120. The length direction X of the cross beam body 110 can refer to the width direction of the vehicle body.

[0086] In the embodiment of the present application, the front frame 300 and the cross beam body 110 can be connected by two front module support members 131. The two front module support members 131 can improve the auxiliary support force of the front frame 300 to improve the connection reliability between the cross beam body 110 and the front frame 300. In addition, since the two front module support members 131 are respectively located on both sides of the front cover lock 200, the rigidity, strength and ultimate tensile force of the front cover lock area can also be improved.

[0087] Figure 5 A schematic diagram of the three-dimensional structure of a front collision beam assembly 100 provided in the present application. Figure 5 The outer buffer surface 110 a and the upper plane 110 c of the beam body 110 can be embodied. Figure 6 This is a schematic diagram of the three-dimensional structure of a front collision beam assembly 100 provided in the present application from another perspective. Figure 6 The outer buffer surface 110 a and the lower plane 110 d of the beam body 110 may be embodied.

[0088] In some possible implementations, see Figure 5 As shown, the front impact beam assembly 100 may further include an energy absorption box 140. The beam body 110 may include an outer buffer surface 110a and an inner side surface 110b opposite to each other. The energy absorption box 140 is disposed on the inner side surface 110b of the beam body 110, and the energy absorption box 140 is close to the end of the beam body 110. The front impact beam assembly 100 may further include a reinforcing connector 150. The reinforcing connector 150 connects the beam body 110 and the energy absorption box 140.

[0089] The energy absorption box 140 and the cross beam body 110 are usually connected by welding. When the outer buffer surface 110a of the cross beam body 110 is hit, the weld cracking phenomenon is likely to occur in the welding area between the cross beam body 110 and the energy absorption box 140. The cracking of the weld seam is likely to cause the cross beam body 110 to separate from the energy absorption box 140, and the cross beam body 110 to fall off, so that the collision force received by the cross beam body 110 cannot be absorbed by the energy absorption box 140 and the longitudinal beam, affecting the transmission and absorption of the collision force.

[0090] In the embodiment of the present application, the reinforcing connector 150 can be used to improve the connection reliability between the cross beam body 110 and the energy absorption box 140. When the cross beam body 110 is hit and the weld between the cross beam body 110 and the energy absorption box 140 is cracked, the reinforcing connector 150 can keep the cross beam body 110 and the energy absorption box 140 connected, so that the impact force on the cross beam body 110 can be transmitted to and absorbed by the energy absorption boxes 140 on both sides, thereby reducing safety hazards and maintenance costs.

[0091] In some examples, the reinforcing connector 150 can be detachably connected to the cross beam body 110 and the front end frame 300 via a locking member.

[0092] In some examples, the reinforcing connector 150 may be, but is not limited to, disposed on the upper plane 110c of the cross beam body 110 and the front end frame 300. For example, the upper plane 110c of the cross beam body 110 and the front end module is provided with the reinforcing connector 150, and the lower plane 110d of the cross beam body 110 and the front end frame 300 is also provided with the reinforcing connector 150.

[0093] In some examples, the reinforcing connector 150 may include a first plate 151 and a second plate 152. The first plate 151 may be connected to the cross beam body 110, and the second plate 152 may be used to connect to the front frame 300. Specifically, when the upper plane 110c of the cross beam body 110 and the upper plane 110c of the front frame 300 have a height difference, the first plate 151 and the second plate 152 may be in a stepped structure, so that the first plate 151 and the upper plane 110c of the cross beam body 110 can be closely fitted, and the second plate 152 and the upper plane 110c of the front frame 300 can be closely fitted.

[0094] In some possible implementations, see Figure 6 As shown, energy absorbing boxes 140 may be provided at both ends of the cross beam body 110 along the length direction X of the cross beam body 110. A mounting plate 160 may be provided on the side of the energy absorbing box 140 facing away from the cross beam body 110. The mounting plate 160 may be used to fix the longitudinal beam. The cross beam body 110 is provided with a towing hook cover 170, and the front collision cross beam assembly 100 further includes a reinforcing plate 180, which connects the energy absorbing box 140 and the mounting plate 160 near the towing hook cover 170.

[0095] When a vehicle breaks down or gets stuck in bad road conditions and cannot move on its own, it needs to be towed by other vehicles using a towing rope or towing rod to get the vehicle out of the bad road conditions or to a repair point. In the process of towing a trailer, the vehicle hook needs to be fixed to the towing hook sleeve 170 of the cross beam body 110 to tow the vehicle out of trouble. Therefore, the cross beam body 110 is subjected to a large traction force at the towing hook sleeve 170, which can easily cause the weld between the energy absorption box 140 and the mounting plate 160 near the towing hook to crack, thereby affecting the transmission of the collision force.

[0096] In the embodiment of the present application, a reinforcement plate 180 may be provided to improve the connection reliability between the energy absorption box 140 and the mounting plate 160 , thereby reducing the possibility that the weld between the energy absorption box 140 and the mounting plate 160 may crack and separate, thereby affecting the transmission of collision force.

[0097] In some examples, the reinforcing plate 180 may include a third plate body 181 and a fourth plate body 182. The third plate body 181 may be used to connect to the energy absorbing box 140. The third plate body 181 and the energy absorbing box 140 may be detachably connected. The fourth plate body 182 may be used to connect to the mounting plate 160.

[0098] Exemplarily, the third plate body 181 and the fourth plate body 182 may be connected by a reinforcing rib 183. The reinforcing rib 183 may also be a plate structure. The reinforcing rib 183 and the third plate body 181 may have an angle, so that the reinforcing plate 180, the energy absorbing box 140, and the mounting plate 160 may form a triangular stable support structure to more effectively improve the connection stability of the energy absorbing box 140 and the mounting plate 160.

[0099] In some possible implementations, see Figure 5 and Figure 6 As shown, the cross beam body 110 of the embodiment of the present application may also have at least one set of opposite planes. The cross beam body 110 may be provided with a plurality of mounting holes 111. The number of mounting holes 111 on the plane may be greater than the number of mounting holes 111 on the outer buffer surface 110a and the inner side surface 110b.

[0100] The outer buffer surface 110a of the cross beam body 110 refers to the surface facing the collision object. The outer buffer surface 110a and the inner side surface 110b are both curved surfaces. When the cross beam body 110 is hit by the collision object, the impact force received by the cross beam body 110 can be transmitted along the curved surface to both sides of the cross beam body 110 and dispersed to the energy absorbing box 140 and the longitudinal beam, and part of the impact force is absorbed by the energy absorbing box 140 and the longitudinal beam.

[0101] The cross beam body 110 is provided with a plurality of mounting holes 111. Specifically, the mounting holes 111 can be used to connect with the front frame 300, the wind deflector and other structures, or the mounting holes 111 can also be used to fix the wiring harness, the liquid cooling pipe and other structures.

[0102] Since the outer buffer surface 110a and the inner side surface 110b are curved surfaces, if the mounting holes 111 are set on the outer buffer surface 110a and the inner side surface 110b, stress concentration is likely to occur and cracks may occur from the edge of the mounting holes 111, which may easily affect the connection reliability between the front frame 300, the wind deflector and other structures and the crossbeam body 110. In the embodiment of the present application, most of the mounting holes 111 can be set on the plane of the crossbeam body 110 to reduce the possibility of the mounting holes 111 cracking on the outer buffer surface 110a.

[0103] In some examples, some of the mounting holes 111 may be disposed on the upper plane 110c of the beam body 110. Figure 1 and Figure 5 As shown, along the reverse direction of the length of the cross beam body 110 , the two mounting holes 111 on both sides of the first connecting member 121 can be used to connect with the front-end module support member 131 .

[0104] In some examples, some of the mounting holes 111 may be disposed on the lower plane 110d of the cross beam body 110. The mounting holes 111 located on the lower plane 110d of the cross beam body 110 may be used to fix the wiring harness of the vehicle headlight. Alternatively, the mounting holes 111 located on the lower plane 110d of the cross beam body 110 may be used to fix the liquid cooling pipe to dissipate the heat absorbed by the radiator on the front end frame 300.

[0105] In some possible implementations, see Figure 6 As shown, the front impact beam assembly 100 may further include a harness bracket 190. The harness bracket 190 may be disposed on at least one plane of the beam body 110. The harness bracket 190 is provided with a through hole.

[0106] In the embodiment of the present application, the harness bracket 190 can be used to fix the harness of the vehicle headlight. Specifically, when the vehicle is an extended-range vehicle, a liquid cooling pipe needs to be provided to dissipate the heat generated in the front cover. The liquid cooling pipe can be fixed through the mounting hole 111 of the lower plane 110d of the crossbeam body 110. Part of the harness bracket 190 can protrude from the inner side 110b of the crossbeam body 110. The protruding part of the harness bracket 190 can be provided with a through hole for fixing the harness of the vehicle headlight.

[0107] In some examples, the number of the harness brackets 190 may be, but is not limited to, four. The harness brackets 190 may be welded to the lower side of the beam body 110 .

[0108] The embodiment of the present application also provides a vehicle, which may include a front hood lock 200, a front end frame 300 and a front collision beam assembly 100 in any of the above embodiments. The front collision beam assembly 100 is connected to the front hood lock 200 through a front hood lock connecting assembly 120, and the front collision beam assembly 100 is connected to the front end frame 300 through a front end module connecting assembly 130.

The above are only preferred embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
