Abstract
Description
Technical Field
[0001] This application relates to the field of bumper technology, and more particularly to a front bumper device and vehicle. Background Technology
[0002] Heavy-duty trucks and all-wheel-drive vehicles are typically used in high-load, complex terrain transportation scenarios, such as mines, deserts, mountains and other wilderness environments.
[0003] In related technologies, vehicle front bumper devices typically employ either metal or plastic bumper structures. Metal bumper structures often use a split design, but the connections between components, such as welded joints and bolted connections, are prone to fatigue fracture under long-term vibration and impact, resulting in insufficient overall rigidity. While plastic bumper structures are lightweight, they are unable to withstand the frontal impact forces of high-speed vehicle travel and the towing forces of trailers, making them susceptible to deformation or breakage.
[0004] Therefore, there is an urgent need to provide a front bumper device with high rigidity and good structural reliability. Utility Model Content

[0025] The positioning part is slidably disposed on the cylindrical part, and part of the positioning part passes through the positioning hole to lock the pedal part and the second assembly part.
[0026] The elastic part and the positioning part are connected to the cylinder part through the elastic part. The positioning part is configured to slide away from the positioning hole under the action of external force before the pedal part rotates, so as to disengage from the positioning hole and compress the elastic part, thereby unlocking the pedal part from the second assembly part. The elastic part is configured to reset when the external force disappears, so as to drive the positioning part to slide in the direction close to the positioning hole.
[0027] In one possible implementation, the front bumper device provided in this application has an anti-slip layer on the side of the first pedal opposite to the first connecting portion; and / or,
[0028] The pedal surface is a non-slip surface; and / or,
[0029] A tow hook is provided in the middle of the first connecting part, and the tow hook and the first assembly part are located on the same side of the first connecting part.

The first connecting portion is connected to the vehicle frame, and the side bumper assemblies are also connected to the vehicle frame. Simultaneously, the diagonal braces connect the support plates to the vehicle frame.
[0033] Thus, because the front bumper assembly is connected to the frame at multiple points, when the vehicle is subjected to a frontal impact or towing force, the force can be distributed and transmitted to the frame through the front bumper assembly, avoiding overload failure at a single connection point and improving structural reliability. Since the diagonal brace connects the support plate to the frame, it forms a stable triangular mechanical structure with the support plate and the frame. This force transmission path effectively resists longitudinal impact loads and vertical vibrations, which helps improve the rigidity of the front bumper assembly. Attached Figure Description

[0055] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.
[0056] Heavy-duty trucks and all-wheel-drive vehicles are typically used in high-load, complex terrain transportation scenarios, such as mines, deserts, mountains and other wilderness environments.
[0057] In related technologies, vehicle front bumper devices typically employ either metal or plastic bumper structures. Metal bumper structures often use a split design, but the connections between components, such as welded joints and bolted connections, are prone to fatigue fracture under long-term vibration and impact, resulting in insufficient overall rigidity. While plastic bumper structures are lightweight, they are unable to withstand the frontal impact forces of high-speed vehicle travel and the towing forces of trailers, making them susceptible to deformation or breakage.
[0058] Therefore, there is an urgent need to provide a front bumper device with high rigidity and good structural reliability.
[0059] In view of this, this application provides a front bumper device and a vehicle. The front bumper device is installed at the front of the vehicle frame. The front bumper device includes a lower bumper assembly, two side bumper assemblies, and two support components. The lower bumper assembly includes a first connecting portion and two second connecting portions, which are respectively located at both ends of the first connecting portion. The side bumper assemblies are correspondingly installed above the second connecting portions. The support components correspond to the side bumper assemblies and include support plates and diagonal braces. The side bumper assemblies are connected to the second connecting portions through corresponding support plates. The first connecting portion is connected to the vehicle frame, and the side bumper assemblies are also connected to the vehicle frame. Simultaneously, the diagonal braces connect the support plates to the vehicle frame.
[0060] Thus, because the front bumper assembly is connected to the frame at multiple points, when the vehicle is subjected to a frontal impact or towing force, the force can be distributed and transmitted to the frame through the front bumper assembly, avoiding overload failure at a single connection point and improving structural reliability. Since the diagonal brace connects the support plate to the frame, it forms a stable triangular mechanical structure with the support plate and the frame. This force transmission path effectively resists longitudinal impact loads and vertical vibrations, which helps improve the rigidity of the front bumper assembly.
[0061] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0062] See Figures 1 to 4 The front bumper device 100 provided in this application embodiment is used to be installed in front of the vehicle frame 200. It includes a lower bumper assembly 110, two side bumper assemblies 120 and two support components 130. The lower bumper assembly 110 includes a first connecting part 111 and two second connecting parts 112. The two second connecting parts 112 are respectively disposed at both ends of the first connecting part 111. The first connecting part 111 is connected to the vehicle frame 200.
[0063] The side bumper assemblies 120 are respectively disposed above the second connecting parts 112, and the side bumper assemblies 120 are connected to the vehicle frame 200; the support components 130 are respectively corresponding to the side bumper assemblies 120, and the support components 130 include support plate members 131 and diagonal braces 132. The side bumper assemblies 120 are connected to the second connecting parts 112 through the corresponding support plate members 131, and the diagonal braces 132 are used to connect the support plate members 131 and the vehicle frame 200.
[0064] It should be noted that the front bumper device 100 of this application embodiment can be applied to heavy-duty all-wheel drive trucks, mining dump trucks, off-road engineering vehicles, military tactical vehicles, and high-load transport vehicles used in complex unpaved roads such as deserts, mountains, Gobi, and forest areas. This application embodiment does not limit this application.
[0065] The lower bumper assembly 110 is the main load-bearing component, including a first connecting part 111 located in the middle and two second connecting parts 112 respectively located at the left and right ends of the first connecting part 111. The first connecting part 111 and the second connecting part 112 can be manufactured by an integral molding process, such as forming a continuous rigid frame by integral stamping or bending and welding of high-strength steel plates, thereby ensuring the integrity of the structure and its resistance to deformation.
[0066] The first connecting part 111 is provided with a mounting interface for connecting to the frame 200. The mounting interface can be specifically configured as multiple connecting holes 160 to achieve a stable connection with the frame 200, ensuring that the trailer pull force or frontal collision load can be effectively transferred to the entire vehicle frame.
[0067] The side bumper assemblies 120 are correspondingly positioned above the second connecting portions 112. The side bumper assemblies 120 can be made of metal materials, such as high-strength steel or aluminum alloy, to provide sufficient structural strength and rigidity. Specifically, the side bumper assemblies 120 are constructed by... Figure 2 The side bumper body 121, the first back plate 122, and the second back plate 123 shown are assembled together; the side bumper assembly 120 can be used to install lighting devices such as headlights and fog lights, and can also bear part of the structural force transmission function.
[0068] By correspondingly configuring the support components 130 with the two side bumper assemblies 120, each support component 130 includes two parts: a support plate 131 and a diagonal brace 132. The support plate 131 can be a metal plate structure, with one end fixedly connected to the corresponding side bumper assembly 120 and the other end connected to the second connecting part 112. This connects the side bumper assembly 120 and the lower bumper assembly 110 in the lateral direction, forming a lateral support frame, which helps to share the load in the event of an offset collision or lateral impact.
[0069] It is understood that in the description of the embodiments in this application, the up and down direction corresponds to the height direction of the vehicle, which can be referred to as... Figure 1 The Z direction; the lateral direction corresponds to the width of the vehicle, which can be referenced. Figure 1 X direction in
[0070] The diagonal brace 132 is arranged at an angle. The upper end of the diagonal brace 132 is connected to the middle area of the support plate 131, and the lower end is connected to the frame 200, thus forming a stable triangular mechanical structure together with the support plate 131 and the frame 200. This triangular force transmission path can effectively resist longitudinal impact force and vertical vibration load when the vehicle encounters a high-speed frontal collision, towing operation, or driving on bumpy and complex terrain, thereby improving the bending, torsional, and fatigue resistance of the entire front bumper assembly 100.
[0071] Since the lower bumper assembly 110, the two side bumper assemblies 120 and the two support components 130 are all connected to the frame 200 at multiple points, the main mounting points of each module are concentrated on the frame 200, resulting in a compact relative position and good precision. At the same time, external loads can be distributed to the frame 200 through multiple paths such as the central tow hook 1111, the side bumper assemblies 120 on both sides and the diagonal brace structure, avoiding connection failure due to local stress concentration.
[0072] For example, when a vehicle is subjected to a frontal collision or towing force, the longitudinal impact force is mainly applied along the vehicle's forward direction to the central tow hook 1111 and the lower bumper assembly 110. At this time, the force can be transmitted to the support plate 131 through the second connection 112, and then diagonally guided to the frame 200 via the diagonal brace 132, forming a multi-path dispersion mechanism from "central → lower side → frame 200", avoiding the load from being concentrated at a single weld point or bolt connection.
[0073] When a vehicle is traveling on a bumpy road, vertical vibrations and impacts from the ground can cause the front bumper device 100 to sway up and down. The diagonal brace 132 provides vertical constraint stiffness by being arranged at an angle, suppressing vertical displacement and reducing alternating stress at the connection points, thereby delaying the initiation and propagation of fatigue cracks.
[0074] In some examples, the front bumper assembly 100 also includes a grille assembly 140 disposed above the first connection portion 111; the lower bumper assembly 110 and the two side bumper assemblies 120 are detachably connected to the grille assembly 140, which is connected to the frame 200.
[0075] The grille assembly 140 can serve as a ventilation and decoration feature, while also functioning as a structural connection.
[0076] The grille assembly 140 is made of metal or high-strength composite material. The first connecting part 111 of the lower bumper assembly 110 and the two side bumper assemblies 120 are detachably connected to the grille assembly 140, for example, by using a bolt connection structure, so as to facilitate assembly, maintenance or individual replacement in case of local damage, thereby reducing maintenance costs.
[0077] Specifically, the lower edge of the grille assembly 140 may be provided with a connection interface corresponding to the first connection part 111. One of the sides of the grille assembly 140 and the side bumper assembly 120 is provided with mounting ears aligned with the other, ensuring that the three components form a stable front-end frame structure after assembly. Simultaneously, the grille assembly 140 itself is also connected to the vehicle frame 200. For example, multiple connection holes 160 can be provided on its back, allowing it to be fixed to the corresponding mounting points of the vehicle frame 200 using bolts or other fasteners, thereby integrating the grille assembly 140 into the overall force transmission system.
[0078] Thus, the grille assembly 140 can serve as an exterior cover and also participate in load transfer structurally. When the vehicle is subjected to frontal impact or long-term vibration, it can work in conjunction with the lower bumper assembly 110, the side bumper assembly 120, and the support component 130 to further enhance the overall rigidity and stability of the front bumper device 100, while also taking into account modular design and ease of maintenance.
[0079] See Figure 2 , Figure 4 and Figure 5 In a specific example, the grille assembly 140 includes a grille assembly body 141 and a reinforcing beam 142. The grille assembly body 141 has a plurality of first insertion portions 1411 and a plurality of second insertion portions (not shown in the figure) on a first connecting portion 111. The first insertion portions 1411 and the second insertion portions are inserted into each other in a one-to-one correspondence. The reinforcing beam 142 is connected between two side bumper assemblies 120. The reinforcing beam 142 and the two side bumper assemblies 120 are detachably connected to the grille assembly body 141.
[0080] In this embodiment, the overall outline of the grille assembly 141 can be adapted to the front styling of the vehicle. The interior of the grille assembly 141 is provided with ventilation openings or decorative mesh, and a plurality of first insertion portions 1411 are provided in its lower region. Correspondingly, the first connecting portion 111 of the lower bumper assembly 110 is provided with a plurality of second insertion portions in a one-to-one correspondence in number and position. The first insertion portions 1411 and the second insertion portions achieve quick positioning and detachable connection between the grille assembly 141 and the lower bumper assembly 110 through insertion and engagement.
[0081] The number of the first plug-in portion 1411 and the second plug-in portion can both be set to four, and the first plug-in portion 1411 can be along... Figure 1 The X-direction spacing is set. The first plug part 1411 can be constructed as a protruding buckle or a plug tongue structure with a guide bevel, while the second plug part is correspondingly configured as a matching slot, a plug hole 1012 or a receiving seat with a limiting shoulder. The two are stably connected by mechanical interlocking formed after insertion.
[0082] Furthermore, the reinforcing beam 142 is arranged laterally between the two side bumper assemblies 120, located behind or inside the grille assembly 141, with its two ends fixedly connected to the left and right side bumper assemblies 120 respectively, to improve the overall rigidity of the front bumper device 100 in the lateral direction.
[0083] The reinforcing beam 142 and the two side bumper assemblies 120 are both detachably connected to the grille assembly 141, for example, by means of bolted connections to achieve modular assembly.
[0084] In practice, when assembling the front bumper assembly 100, the lower bumper assembly 110 and the two side bumper assemblies 120 are assembled first, then the reinforcing beam 142 is installed, and finally the grille assembly 141 is installed.
[0085] See Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7As shown, in some examples, the front bumper assembly 100 also includes a pedal assembly 150, which includes a first pedal 151 and a second sub-pedal assembly 152. The first pedal 151 is fixed above the first connecting portion 111 by a pin 1511. The second sub-pedal assembly 152 and the tow hook 1111 are both located on the same side of the first connecting portion 111. The second sub-pedal assembly 152 is rotatably connected to the first connecting portion 111 and has a pedal surface 1011.
[0086] The second sub-pedal assembly 152 is configured to rotate relative to the first connecting portion 111 to switch between a storage position and a use position. In the storage position, the pedal surface 1011 is located above the first pedal 151 and is positioned downwards. In the use position, the pedal surface 1011 is located below the first pedal 151 and is positioned upwards.
[0087] The pedal assembly 150 is used to provide operators with foot support when boarding or performing maintenance, and is suitable for heavy vehicles such as heavy-duty trucks and all-wheel drive vehicles.
[0088] In this embodiment, the second sub-pedal assembly 152 is configured to switch between a storage position and a use position. When in the storage position, the second sub-pedal assembly 152 flips upward and retracts above the first pedal 151, with the pedal surface 1011 facing downward, as shown below. Figure 4 As shown; when needed, the second sub-pedal assembly 152 is flipped downwards to the usage position, at which time the pedal surface 1011 is located below the first pedal 151 and facing upwards, as shown. Figure 7 As shown, a two-stage step is formed below the first pedal 151, which facilitates the operator to climb step by step to reach the high area of the front of the vehicle for maintenance, cleaning or loading operations.
[0089] For example, after the front bumper device 100 is installed on the vehicle, the first pedal 151 is 0.8 meters off the ground, making it inconvenient for the operator to step directly on it. With the setting of the second sub-pedal assembly 152, when it is in the use position, the pedal surface 1011 is located below the first pedal 151. The pedal surface 1011 is 0.3 meters to 0.4 meters off the ground, such as 0.3 meters, 0.35 meters or 0.4 meters, so that the operator can first naturally step onto the pedal surface 1011 and then step onto the first pedal 151, improving the convenience and safety of getting on and off.
[0090] In some examples, the second sub-pedal assembly 152 includes a pedal component 101, an assembly component 102, and a rotating component 103. The pedal component 101 has a pedal surface 1011. The assembly component 102 includes a first mounting portion 1021 and a second mounting portion 1022 disposed on the first mounting portion 1021. The side of the first mounting portion 1021 facing away from the second mounting portion 1022 is connected to a first connecting portion 111. The pedal component 101 is rotatably connected to the second mounting portion 1022 via the rotating component 103. The pedal component 101 is used to drive the pedal surface 1011 to rotate relative to the first connecting portion 111.
[0091] Thus, the pedal component 101, the mounting component 102, and the rotating component 103 work together to achieve the flip-up function of the pedal surface 1011.
[0092] The first assembly part 1021 is securely connected to the first connecting part 111 on the side opposite to the second assembly part 1022 by welding, bolts or other fastening methods, ensuring that the entire second sub-pedal assembly 152 has a reliable mounting base. The second assembly part 1022 extends upward or outward from the first assembly part 1021 to provide a pivot point for the rotation of the pedal part 101.
[0093] The pedal component 101 is rotatably connected to the second assembly part 1022 via the rotating component 103. The rotating component 103 can be configured as a pin, hinge, pivot or rotating mechanism with bearings, allowing the pedal component 101 to rotate relative to the second assembly part 1022 about a horizontal axis, thereby driving the pedal surface 1011 as a whole to switch between the storage position and the use position relative to the first connecting part 111.
[0094] It should be noted that the direction of the horizontal axis is the reference. Figure 1 The X direction in the equation.
[0095] For example, combined Figure 5 and Figure 6 As shown, the pedal component 101 has an overall U-shaped structure, with two symmetrically arranged side arms of the U-shape, and the bottom crossbeam forming the main support area. The pedal surface 1011 is located on the upper surface of the U-shaped pedal component 101, specifically on the continuous plane formed by the bottom crossbeam of the U-shape and the upper edges of the two side arms, ensuring sufficient support area and stability when the operator steps on it.
[0096] Correspondingly, there are two mounting parts 102, respectively arranged on both sides of the U-shaped opening of the pedal component 101. Each mounting part 102 includes a first mounting part 1021 and a second mounting part 1022 disposed thereon. The two first mounting parts 1021 are respectively fixedly connected to the left and right sides of the first connecting part 111 of the lower bumper assembly 110, so that the positions of the two second mounting parts 1022 correspond one-to-one with the U-shaped side arms of the pedal component 101. The ends of the two side arms of the pedal component 101 are rotatably connected to the corresponding second mounting parts 1022 through rotating parts 103, so that the entire U-shaped pedal component 101 can rotate synchronously around the two rotating points as the axis.
[0097] Thus, the symmetrical connection of the pedal component 101 on both sides helps to improve the stability of the rotation process and can also distribute the stepping load, avoiding twisting or loosening caused by unilateral force, thereby maintaining structural reliability and smooth operation during the switching between storage and use.
[0098] In a specific implementation, the second sub-pedal assembly 152 further includes a positioning member 104; the positioning member 104 is disposed on the first assembly part 1021, the pedal part 101 is connected to the positioning member 104, and the positioning member 104 is configured to connect or disconnect from the second assembly part 1022 to lock or unlock the pedal part 101 from the second assembly part 1022.
[0099] Thus, by setting the positioning element 104, the pedal element 101 can be reliably locked when it is in the storage position or the use position, preventing the pedal element 101 from rotating unexpectedly due to vibration or external force during vehicle operation or use.
[0100] In this embodiment, when the pedal component 101 is flipped downwards to the use position, the positioning component 104 connects with the second assembly part 1022, locking the pedal component 101 relative to the second assembly part 1022 to ensure that the pedal surface 1011 remains stable when bearing the pedal load. When it needs to be stored, the operator disengages the positioning component 104 from the second assembly part 1022, thereby releasing the locking state and allowing the pedal component 101 to flip upwards. In the stored position, the positioning component 104 re-engages with the second assembly part 1022, locking the pedal component 101 in the folded state to prevent it from sagging or shaking due to bumps during driving.
[0101] In some embodiments, the second assembly portion 1022 is provided with a positioning hole 1023, and the positioning member 104 includes a cylindrical portion 1041, a positioning portion 1042 and an elastic portion 1043. The cylindrical portion 1041 is disposed on the first assembly portion 1021, and the pedal member 101 is provided with an insertion hole 1012. A portion of the cylindrical portion 1041 is inserted into the insertion hole 1012. The positioning portion 1042 is slidably disposed on the cylindrical portion 1041, and a portion of the positioning portion 1042 passes through the positioning hole 1023 to lock the pedal member 101 and the second assembly portion 1022.
[0102] The positioning part 1042 is connected to the cylinder part 1041 via the elastic part 1043. The positioning part 1042 is configured to slide away from the positioning hole 1023 under the action of an external force before the pedal part 101 rotates, so as to disengage from the positioning hole 1023 and compress the elastic part 1043, thereby unlocking the pedal part 101 from the second assembly part 1022. The elastic part 1043 is configured to reset when the external force disappears, so as to drive the positioning part 1042 to slide in the direction close to the positioning hole 1023.
[0103] The positioning part 1042 can be slidably disposed on the outer periphery of the cylindrical part 1041 and move along the axial direction of the cylindrical part 1041; or, the cylindrical part 1041 has a receiving cavity, and the positioning part 1042 can be slidably disposed in the receiving cavity, so that the overall structure of the positioning member 104 is more compact.
[0104] One end of the positioning part 1042 can be configured as a protrusion or pin-like structure that can pass through the positioning hole 1023 on the second assembly part 1022. When the pedal part 101 is in the use position or the storage position, a portion of the positioning part 1042 passes through the positioning hole 1023, thereby locking the pedal part 101 and the second assembly part 1022 in the rotational direction to prevent them from accidentally flipping over.
[0105] The positioning part 1042 is connected to the cylinder part 1041 via the elastic part 1043. The elastic part 1043 can be a compression spring, a spring sheet, or other elastic element with a reset function. Under normal conditions, the elastic part 1043 pushes the positioning part 1042 to extend toward the positioning hole 1023. When it is necessary to rotate the pedal part 101, the operator applies external force to the positioning part 1042, causing the positioning part 1042 to overcome the elastic force of the elastic part 1043 and slide away from the positioning hole 1023, disengaging from the positioning hole 1023. At the same time, the elastic part 1043 is compressed, and the pedal part 101 is unlocked from the second assembly part 1022, allowing it to rotate freely.
[0106] When the external force is removed and the pedal component 101 is flipped to the target position, the elastic part 1043 releases the stored energy, which drives the positioning part 1042 to automatically reset and re-insert into the positioning hole 1023, thereby achieving reliable locking.
[0107] Thus, through the structural design of the positioning component 104, the overall operation is simple, the locking is stable, and both safety and ease of operation are taken into account.
[0108] Of course, in other embodiments, the positioning part 1042 can also be adapted to a lever-type locking tongue structure, and a corresponding locking seat can be provided on the pedal part 101. This application embodiment will not elaborate on this.
[0109] To improve the safety and stability of the operator when stepping on the pedal assembly 150, in a specific example, the first pedal 151 has an anti-slip layer on the side opposite to the first connecting part 111; and / or, the pedal surface 1011 is an anti-slip surface.
[0110] The anti-slip layer can be made of rubber, thermoplastic elastomer, textured composite material, or can be attached to the surface of the metal substrate by spraying, bonding, or coating. The surface of the anti-slip layer has anti-slip patterns such as raised and recessed textures, granular protrusions, diamond grids, or linear grooves to increase the coefficient of friction and prevent slippage in rain, snow, mud, or oily environments.
[0111] The anti-slip surface can be an integrally formed anti-slip serration during the manufacturing of the pedal component 101 by metal sheet stamping, or it can be an anti-slip insert or welded anti-slip strip embedded in the area of the pedal component 101 where the pedal surface 1011 is arranged. This application embodiment does not limit this.
[0112] For example, the anti-slip design can be applied to the first pedal 151 or the pedal surface 1011 alone, or both can be used simultaneously to form a double anti-slip guarantee.
[0113] In some other embodiments, a tow hook 1111 is provided in the middle of the first connecting part 111, and the tow hook 1111 and the first assembly part 1021 are located on the same side of the first connecting part 111.
[0114] With the tow hook 1111 installed, the vehicle can be towed after the front bumper device 100 is installed on the vehicle.
[0115] The tow hook 1111 can be directly integrated into the first connecting part 111, or it can be fixed by high-strength bolts or welding. This application embodiment does not limit this.
[0116] See 3. Figure 4 and Figure 7 As shown, this application embodiment also provides a vehicle, including a frame 200 and a front bumper device 100 connected to the frame 200 as described in any of the above embodiments.
[0117] The specific structure and working method of the front bumper device 100 have been described in detail in the above embodiments, and will not be repeated here.
[0118] In some examples, the frame 200 includes a cylindrical beam 221 and two brackets 222. The cylindrical beam 221 is connected between the two brackets 222. The first connecting portion 111 of the lower bumper assembly 110 is connected in sequence to one of the two brackets 222, the cylindrical beam 221, and the other of the two brackets 222. The side bumper assembly 120 is connected to the brackets 222 in a one-to-one correspondence. The end of the reinforcing beam 142 of the front bumper device 100 near the side bumper assembly 120 is connected to the brackets 222 in a one-to-one correspondence.
[0119] The circular tube beam 221 is arranged laterally, and its two ends are rigidly connected to two supports 222 respectively to form a stable load-bearing frame. The frame 200 may also include a frame body 210. The supports 222 and the circular tube beam 221 are formed by casting and set at the front end of the frame body 210. The two supports 222 extend rearward and are fixed to the frame body 210 by welding, bolts or other means to ensure that the frame 200 as a whole has sufficient strength and rigidity.
[0120] The first connecting portion 111 of the lower bumper assembly 110 is along the width direction of the vehicle, i.e., reference Figure 7 The X-direction is connected sequentially to one of the supports 222, the middle circular tube beam 221, and another support 222, forming a multi-point continuous connection structure, which effectively disperses the concentrated load in the middle.
[0121] For example, such as Figure 7 As shown, the first connecting part 111 can be connected to the frame 200 through eight fixing points. The eight fixing points include four bracket 222 fixing points arranged symmetrically in pairs and four circular tube beam 221 fixing points arranged symmetrically in pairs. Among them, the fixing points are the connecting holes 160 shown in the figure, which are used to fix the first connecting part 111 and the frame 200 with screws.
[0122] By connecting the two side bumper assemblies 120 to their corresponding brackets 222, the forces on the left and right sides can be directly transmitted to the brackets 222 and further transferred to the vehicle frame body 210. In addition, the end of the reinforcing beam 142 near the side bumper assembly 120 is connected to the bracket 222, further integrating the grille assembly 140, the side bumper assembly 120, and the vehicle frame 200 into a cohesive structural unit that shares the load.
[0123] The connection method between the side bumper assembly 120 and the bracket 222, and the connection method between the reinforcing beam 142 and the bracket 222 can refer to the connection method between the first connecting part 111 and the frame 200 mentioned above. This application embodiment will not elaborate on this further.
[0124] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
