Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle parts, and more specifically, to a vehicle front-end assembly and a vehicle. Background Technology
[0002] The front-end assembly is a crucial component of a vehicle. With the increasing diversity of vehicle front-end designs, the matching of its various components becomes more challenging, making it highly susceptible to inadequate pedestrian collision safety protection. In related technologies, to meet pedestrian collision safety regulations, the strength of components such as the front bumper bracket and front frame of the front-end assembly is typically reduced. This allows the front-end assembly to crumple and deform promptly after a rearward impact from a pedestrian in the X-direction, ensuring pedestrian safety. However, this approach can lead to abnormal noises from the components during vehicle operation, fatigue and durability failure, and a reduced service life. Utility Model Content
[0003] This utility model aims to solve the technical problem in related technologies that the front-end assembly of a vehicle cannot simultaneously meet the needs of pedestrian collision safety and its own strength.
[0004] In a first aspect, this utility model provides a vehicle front-end assembly, including a front bumper bracket, a front frame, and a sliding bracket. The sliding bracket includes a bracket body and a hook disposed on the bracket body. The bracket body is mounted on the front bumper bracket. The hook is positioned with its engagement direction facing the rear of the vehicle. The front frame is provided with a locking hole for engaging with the hook. The hook is used to deform under pressure when the front bumper bracket is subjected to an impact force facing the rear of the vehicle to disengage from the locking hole, so that the bracket body can slide relative to the front frame towards the rear of the vehicle.
[0005] Optionally, the sliding bracket includes two hooks, which are located at both ends of the bracket body along the left-right direction of the vehicle, and the locking holes are configured to correspond one-to-one with the hooks.
[0006] Optionally, the bracket body includes a first plate and a second plate, with two second plates disposed opposite each other at both ends of the first plate along the left-right direction of the vehicle. The first plate and the two second plates enclose each other to form a groove-shaped structure with the groove opening facing upward. A portion of the front bumper bracket is placed within the groove-shaped structure and connected to the first plate. The two second plates are respectively provided with corresponding hooks.
[0007] Optionally, the second plate has a clearance hole extending through its thickness direction, the hook is located in the clearance hole, and the fixed end of the hook is connected to the hole wall of the clearance hole near the rear of the vehicle.
[0008] Optionally, the vehicle front-end assembly also includes a fastener, the first plate has a first connecting hole, the front bumper bracket has a second connecting hole, and the fastener passes through the first connecting hole and the second connecting hole in sequence;
[0009] And / or, the first plate is provided with a positioning structure, and the front bumper bracket is provided with a positioning mating structure that matches the positioning structure.
[0010] Optionally, the sliding bracket further includes a limiting block disposed on the bracket body. The limiting block is used to abut against the front frame when the hook engages with the hole, so as to restrict the sliding bracket from sliding towards the front of the vehicle.
[0011] Optionally, the front frame is provided with a slide rail extending in the front-rear direction of the vehicle, and the bracket body is placed in the slide rail.
[0012] Optionally, the slide rail has a locking hole on its side wall and a through hole extending in the front-rear direction of the vehicle on its bottom wall. The limiting block is located at the bottom of the bracket body and is used to abut against the hole wall facing the front of the vehicle.
[0013] Optionally, the front bumper bracket extends along the left-right direction of the vehicle, and multiple sliding brackets are provided at intervals along the extension direction of the front bumper bracket. The front bumper bracket is connected to the front end frame through the multiple sliding brackets.
[0014] On the other hand, this utility model proposes a vehicle including the aforementioned vehicle front-end assembly.
[0015] The vehicle front-end assembly and vehicle of this utility model have at least the following advantages compared with related technologies:
[0016] The front bumper bracket is mounted on the front bumper. A sliding bracket is installed between the front bumper bracket and the front frame, and the bracket body of the front bumper bracket and the sliding bracket are fixedly connected. The hooks of the sliding bracket engage with the locking holes on the front frame. Since the hooks are engaged towards the rear of the vehicle, the sliding of the front bumper bracket relative to the front frame relative to the rear of the vehicle is restricted, thus achieving the connection between the front bumper bracket and the front frame and ensuring normal vehicle operation. When the front bumper, i.e., the front bumper bracket, is impacted from the rear, it will push the bracket body towards the rear of the vehicle. At this time, the hooks will be compressed and deformed to disengage from the locking holes, and the bracket body can continue to slide towards the rear of the vehicle along with the front bumper bracket. This allows the front bumper and front bumper bracket to slide towards the rear of the vehicle relative to the front frame after a collision, reducing the impact energy of the collision, which is beneficial to pedestrian safety and better meets the collision requirements of pedestrian safety regulations. At the same time, it does not reduce the strength of the front bumper bracket, front frame, and other components of the vehicle's front-end assembly, making the components less prone to collision noises during driving, and improving the fatigue resistance and durability of the components.

Therefore, they should not be construed as limitations on this invention.
[0028] like Figures 2-5 As shown in the figure, a vehicle front-end assembly according to an embodiment of the present invention includes a front bumper bracket 1, a front frame 2, and a sliding bracket 3. The sliding bracket 3 includes a bracket body 31 and a hook 32 provided on the bracket body 31. The bracket body 31 is mounted on the front bumper bracket 1. The hook 32 is positioned with its engagement direction facing the rear of the vehicle. The front frame 2 is provided with a locking hole 21 for engaging with the hook 32. The hook 32 is used to deform under pressure when the front bumper bracket 1 is subjected to an impact force facing the rear of the vehicle to disengage from the locking hole 21, so that the bracket body 31 can slide relative to the front frame 2 towards the rear of the vehicle.
[0029] Specifically, such as Figure 1As shown, the front bumper 4 is located in front of the front frame 2. The front bumper bracket 1 is mounted on the front bumper 4, which refers to the mounting bracket of the front bumper 4. The front bumper bracket 1 extends towards the front frame 2, that is, towards the rear of the vehicle, to form a connecting part 11. The connecting part 11 is used to connect with the bracket body 31 of the sliding bracket 3. The bracket body 31 of the sliding bracket 3 and the hook 32 can be integrally formed. The rear end of the hook 32 is connected to the bracket body 31, and the front end is bent towards the rear of the vehicle to form a hook. That is, the hooking direction of the hook 32 is set towards the rear of the vehicle. The hook 32 is elastic and can undergo compression deformation. A portion of the front frame 2 is provided with a through hole 21 that runs along the left and right direction of the vehicle. The through hole 21 and the hook 32 are set one-to-one, and the shapes of the through hole 21 and the hook 32 match.
[0030] In this embodiment, a sliding bracket 3 is provided between the front bumper bracket 1 and the front frame 2, and the bracket body 31 of the front bumper bracket 1 and the sliding bracket 3 are fixedly connected. The hook 32 of the sliding bracket 3 engages with the locking hole 21 on the front frame 2. Since the engagement direction of the hook 32 is towards the rear of the vehicle, it can restrict the front bumper bracket 1 from sliding relative to the front frame 2 towards the rear of the vehicle, that is, to achieve the connection between the front bumper bracket 1 and the front frame 2, ensuring the normal use of the vehicle; when the front bumper 4, that is, the front bumper bracket 1, is hit towards the rear of the vehicle, it will push the bracket body 31 towards the vehicle. When the vehicle moves backward, the hook 32 will be squeezed and deformed to disengage from the locking hole 21. The bracket body 31 can continue to slide towards the rear of the vehicle together with the front bumper bracket 1. This allows the front bumper 4 and the front bumper bracket 1 to slide towards the rear of the vehicle relative to the front frame 2 after a collision, reducing the impact energy of the collision, which is beneficial to protecting pedestrian safety and better meeting the collision requirements of pedestrian safety regulations. At the same time, there is no need to reduce the strength of the front bumper bracket 1, the front frame 2 and other components of the vehicle's front assembly, making it less likely for the components to make collision noises during driving, and improving the fatigue resistance and durability of the components.
[0031] like Figure 3 As shown, optionally, the sliding bracket 3 includes two hooks 32, which are located at both ends of the bracket body 31 along the left and right direction of the vehicle, and the locking holes 21 are correspondingly set with the hooks 32.
[0032] In this embodiment, the two hooks 32 in each sliding bracket 3 can be symmetrically arranged at both ends of the bracket body 31 along the left and right direction of the vehicle. The sliding bracket 3 engages with the corresponding holes 21 on the front frame 2 through the hooks 32 at both ends to ensure the stability of the connection between the sliding bracket 3 and the front frame 2 and avoid abnormal noise during driving.
[0033] like Figure 3As shown, optionally, the bracket body 31 includes a first plate 311 and a second plate 312. The two second plates 312 are disposed opposite to each other at both ends of the first plate 311 along the left-right direction of the vehicle. The first plate 311 and the two second plates 312 enclose a groove-shaped structure with the groove facing upward. A portion of the front bumper bracket 1 is placed in the groove-shaped structure and connected to the first plate 311. The two second plates 312 are respectively provided with corresponding hooks 32.
[0034] Specifically, the first plate 311 can be set horizontally, and the second plate 312 can be set vertically. The first plate 311 and the second plates 312 on the left and right sides enclose each other to form a groove-shaped structure with the groove opening facing upward. The part of the front bumper bracket 1, namely the connecting part 11, is horizontally inserted into the groove-shaped structure and is attached to the first plate 311 to realize the connection between the front bumper bracket 1 and the sliding bracket 3. The two second plates 312 of the front bumper bracket 1 are respectively provided with hooks 32. The second plates 312 can be hooked with the corresponding hooks 32 and the corresponding holes 21 of the front frame 2 to realize the connection between the sliding bracket 3 and the front frame 2.
[0035] like Figure 3 As shown, optionally, the second plate 312 is provided with a clearance hole 3121 extending through its thickness direction, the hook 32 is located in the clearance hole 3121, and the fixed end of the hook 32 is connected to the hole wall of the clearance hole 3121 near the rear of the vehicle.
[0036] Specifically, the second plate 312 is arranged vertically, and its thickness direction is the left-right direction, that is, the Y direction. The second plate 312 has a clearance hole 3121 that runs through its thickness direction at a position corresponding to the hook 32. The hook 32 is set in the clearance hole 3121. The hook 32 and the second plate 312 can be stamped from a single flat plate. The clearance hole 3121 is a process hole in the stamping process. The clearance hole 3121 can be an elongated hole arranged in the front-rear direction. The rear end of the hook 32 is a fixed end and is connected to the hole wall of the clearance hole 3121 facing the rear of the vehicle. The front end of the hook 32 is a free end and has a hook part that protrudes out of the clearance hole 3121 and extends out of the second plate 312 (i.e. the side of the second plate 312 facing the outside of the channel structure). When the hook 32 is subjected to the squeezing force along the front and rear of the vehicle, it can deform towards the inside of the second plate 312 (i.e. the side of the second plate 312 facing the inside of the channel structure) so that its hook part can smoothly exit the locking hole 21, so that the sliding bracket 3 together with the front bumper bracket 1 can slide relative to the front frame 2.
[0037] In addition, in order to ensure that the hook of the hook 32 can smoothly exit the locking hole 21 when subjected to the squeezing force along the front and rear of the vehicle, the hooking contact surface of the hook (the surface of the hook facing the rear of the vehicle and used to contact the locking hole 21) can be set as an inclined surface.
[0038] like Figures 2-3 As shown, optionally, the vehicle front assembly also includes fasteners, the first plate 311 is provided with a first connecting hole 3111, the front bumper bracket 1 is provided with a second connecting hole 111, and the fastener passes through the first connecting hole 3111 and the second connecting hole 111 in sequence.
[0039] Here, the fastener can be a bolt. The first plate 311 is provided with a first connecting hole 3111 that passes through along its thickness direction, that is, along the Z direction. The connecting part 11 of the front bumper bracket 1 is provided with a second connecting hole 111 that passes through along the Z direction. Both the first connecting hole 3111 and the second connecting hole 111 can be threaded holes. The fastener passes through the first connecting hole 3111 and the second connecting hole 111 in sequence to achieve a fixed connection between the front bumper bracket 1 and the sliding bracket 3. The connection method is simple and the connection stability is good.
[0040] like Figures 2-3 As shown, optionally, the first plate 311 is provided with a positioning structure 33, and the front bumper bracket 1 is provided with a positioning and mating structure 112 that matches the positioning structure 33.
[0041] Specifically, the first plate 311 is provided with a positioning structure 33 on the side facing the slot. The positioning structure 33 can be integrally formed with the first plate 311, that is, the bracket body 31, to simplify the structural design. The positioning structure 33 can be a positioning rib, and the positioning mating structure 112 can be a positioning hole. By inserting the positioning rib into the positioning hole, the positioning assembly of the front bumper bracket 1 and the sliding bracket 3 can be achieved, ensuring the assembly accuracy.
[0042] Of course, in some cases, the positioning structure 33 can also be a positioning hole, and the positioning mating structure 112 can be a positioning rib.
[0043] like Figures 3-5 As shown, optionally, the sliding bracket 3 further includes a limiting block 34, which is disposed on the bracket body 31. The limiting block 34 is used to abut against the front frame 2 when the hook 32 engages with the hole 21, so as to restrict the sliding bracket 3 from sliding towards the front of the vehicle.
[0044] Specifically, the limiting block 34 can be integrally formed with the bracket body 31 to simplify the structural design. For example, the limiting block 34 can be a protruding rib on the outer side of the first plate 311 (i.e., the side of the first plate 311 facing the outside of the groove structure). With the hook 32 engaging with the locking hole 21 to restrict the sliding bracket 3 from sliding relative to the front frame 2 towards the rear of the vehicle, the limiting block 34 on the bracket body 31 abuts against the corresponding part on the front frame 2, further restricting the sliding bracket 3 from sliding towards the front of the vehicle. This achieves a stable connection between the sliding bracket 3 and the front frame 2, ensuring the normal use of the vehicle.
[0045] like Figures 4-5 As shown, optionally, the front frame 2 is provided with a slide rail 22 extending in the front-rear direction of the vehicle, and the bracket body 31 is placed in the slide rail 22.
[0046] Specifically, the front frame 2 is provided with a U-shaped slide 22 that extends along the front-rear direction of the vehicle and is open at the top. The bracket body 31 is placed in the slide 22. The slide 22 can limit the installation and guide the movement of the bracket body 31, so that when the front bumper bracket 1 is subjected to an impact force toward the rear of the vehicle, the bracket body 31 can slide toward the rear of the vehicle relative to the front frame 2.
[0047] Optionally, the slide 22 has a locking hole 21 on its side wall and a through hole 23 extending along the front-rear direction of the vehicle on its bottom wall. The limiting block 34 is located at the bottom of the bracket body 31 and is used to abut against the hole wall of the through hole 23 facing the front of the vehicle.
[0048] Here, the left and right side walls of the slide 22 are respectively provided with locking holes 21. The bracket body 31 is placed in the slide 22 and can be engaged with the corresponding locking holes 21 through the hooks 32 on its left and right sides. The bottom of the first plate 311 of the bracket body 31 is provided with a limiting block 34. The bottom wall of the slide 22 is provided with a through hole 23 extending in the front-rear direction of the vehicle. The limiting block 34 is located in the through hole 23 and can abut against the hole wall of the through hole 23 facing the front of the vehicle to restrict the sliding bracket 3 from sliding towards the front of the vehicle. When the front bumper bracket 1 is subjected to an impact force towards the rear of the vehicle, the limiting block 34 of the sliding bracket 3 can move smoothly towards the rear of the vehicle along the through hole 23 to allow the sliding bracket 3 to slide towards the rear relative to the front frame 2.
[0049] In addition, the limiting block 34 is located at the bottom of the first plate 311, that is, at the bottom of the bracket body 31, and will not affect the installation of the front frame 2.
[0050] like Figure 2As shown, optionally, the front bumper bracket 1 extends along the left-right direction of the vehicle, and multiple sliding brackets 3 are provided at intervals along the extension direction of the front bumper bracket 1. The front bumper bracket 1 is connected to the front end frame 2 through multiple sliding brackets 3.
[0051] In this embodiment, the front bumper bracket 1 is an elongated structure that extends roughly along the left-right direction of the vehicle. The front bumper bracket 1 is provided with multiple connecting parts 11 at intervals along its extension direction. Each connecting part 11 is connected to the front frame 2 through a corresponding sliding bracket 3. Through multi-point connection, the connection stability between the front bumper bracket 1 and the front frame 2 is better and the force is more even.
[0052] Another embodiment of this utility model provides a vehicle including the aforementioned vehicle front-end assembly. The advantages of the vehicle described in this embodiment compared to the prior art are the same as those of the aforementioned vehicle front-end assembly, and will not be repeated here.
[0053] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
