Description
TECHNICAL FIELD
[0001] The utility model belongs to the related technical field of vehicle front bumper bottom support, especially relates to a vehicle front structure and vehicle. BACKGROUND
[0002] With the popularity and popularity of urban off-road vehicles in recent years, considering the off-road performance and urban comfort and beauty of the whole vehicle has gradually become a key link of the whole vehicle design. It is well known in the industry that a vehicle must have a chassis ground clearance, a large approach angle, etc. if it has certain off-road capability. The front bumper bottom is installed through screwing with the vehicle body chassis or frame. When the approach angle of the front part of the whole vehicle increases, it will increase the risk of the front bumper bottom mounting point leaking.
[0003] At present, a double-layer plate is usually arranged between the front bumper lower body and the calf crash beam of the vehicle, and the double-layer plate is used to support the bottom of the front bumper lower body to ensure that the modal and strength of the front bumper as a whole meet the requirements. However, since a larger assembly space is required when the double-layer plate is assembled between the front bumper lower body and the calf crash beam, the inclination angle of the front bumper lower body when it is inclined upward cannot be large, that is, the double-layer plate cannot meet the requirement of the large approach angle of the front part of the vehicle. UTILITY MODEL CONTENTS
[0004] Therefore, it is necessary to provide a vehicle front structure and vehicle for solving the above technical problems.
[0005] A vehicle front structure, comprising:
[0006] a front bumper lower body having a front inclined part;
[0007] a calf protection bracket arranged behind the front inclined part in the length direction of the vehicle and connected with the front bumper lower body;
[0008] a calf crash beam partially arranged in the area where the front inclined part is located and used to connect a subframe, wherein a gap is formed between the calf crash beam and the front inclined part in the area where the front inclined part is located;

In this process, the assembly of the supporting bracket does not occupy the gap between the lower leg protection beam and the front inclined part of the lower body of the front bumper, so that the inclination angle of the front inclined part can be larger, thereby meeting the requirement of large approach angle of the front part of the vehicle.
[0011] In one of the embodiments, the supporting bracket is connected to the lower leg protection beam and / or the supporting bracket of the lower leg protection bracket in a threaded manner.

[0013] In one of the embodiments, the lower leg protection beam comprises a lower leg protection crossbar, which is arranged above the front inclined part in the vertical direction of the vehicle.
[0014] The supporting bracket comprises a first supporting bracket, the two ends of which are connected to the lower leg protection crossbar and the supporting bracket of the lower leg protection bracket.
[0015] In one of the embodiments, the first supporting bracket comprises a first connecting end, which is arranged on the side of the lower leg protection crossbar away from the front inclined part and connected to the lower leg protection crossbar.
[0016] It can be understood that the connection between the first supporting bracket and the lower leg protection crossbar does not occupy the gap between the lower leg protection crossbar and the front inclined part of the lower body of the front bumper, which can not only make the inclination angle of the front inclined part of the lower body of the front bumper as large as possible to adapt to different styles of vehicles, but also facilitate the assembly and connection of the first connecting end of the first supporting bracket on the lower leg protection crossbar.
[0017] In one of the embodiments, one of the first connecting end and the lower leg protection crossbar is provided with a first positioning hole, and the other is provided with a protruding first positioning member, the first positioning member and the first positioning hole are inserted and matched, and used for assembly and positioning of the first connecting end and the lower leg protection crossbar.
[0018] It can be understood that, through the above structure, the assembly positioning of the first connecting end portion on the first support bracket and the calf anti-collision cross rod can be ensured, so that the assembly position between the first connecting end portion and the calf anti-collision cross rod is accurate, and the subsequent assembly and fixation of the two can be facilitated.
[0019] In one of the embodiments, the first connecting portion between the first support bracket and the calf protection bracket is independently arranged relative to the second connecting portion between the calf protection bracket and the front bumper lower body.
[0020] It can be understood that, through the above structure, the assembly positioning of the first connecting end portion on the first support bracket and the calf anti-collision cross rod can be ensured, so that the assembly position between the first connecting end portion and the calf anti-collision cross rod is accurate, and the subsequent assembly and fixation of the two can be facilitated.
[0021] In one of the embodiments, the calf anti-collision beam comprises an energy absorption box, and the energy absorption box is connected with the auxiliary frame.
[0022] The support bracket comprises a second support bracket, and two ends of the second support bracket are connected with the energy absorption box and the calf protection bracket.
[0023] In one of the embodiments, the second support bracket comprises a second connecting end portion, the second connecting end portion is arranged on a side of the energy absorption box facing the calf protection bracket, and the second connecting end portion is connected with the energy absorption box.
[0024] In one of the embodiments, one of the second connecting end portion and the energy absorption box is provided with a second positioning hole, and the other is provided with a protruding second positioning member, the second positioning member is inserted into the second positioning hole in a matched mode, and the second connecting end portion and the energy absorption box are assembled and positioned.
[0025] It can be understood that, through the above structure, the assembly positioning of the first connecting end portion on the first support bracket and the calf anti-collision cross rod can be ensured, so that the assembly position between the first connecting end portion and the calf anti-collision cross rod is accurate, and the subsequent assembly and fixation of the two can be facilitated.

[0027] Due to the application of the above technical solution, the present application has the following advantages compared with the prior art:
[0028] The vehicle front structure and vehicle claimed in this application utilize the connection between the lower leg protection bracket and the lower body of the front bumper. This allows the lower leg anti-collision beam to provide bottom support for the lower body of the front bumper via the support bracket and the lower leg protection bracket. This satisfies the modal and strength requirements of the lower body of the front bumper and prevents the forward-leaning part of the lower body of the front bumper from colliding with the lower leg anti-collision beam during vehicle operation, thus avoiding abnormal noise caused by the collision. In this process, since the assembly of the support bracket does not occupy the gap between the lower leg anti-collision beam and the forward-leaning part of the lower body of the front bumper, the forward-leaning angle of the forward-leaning part can be larger, which can meet the requirements of a large approach angle of the front of the vehicle.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or at least two of the associated listed items.
[0040] The vehicle front structure 100 claimed in this application is specifically used in vehicles with a chassis having a large approach angle.
[0041] like Figure 1As shown, the vehicle front structure 100 provided in this application includes a front bumper lower body 10, a lower leg protection bracket 20, a lower leg anti-collision beam 30, and at least two support brackets 40. The front bumper lower body 10 has a forward-leaning portion 11. The lower leg protection bracket 20 is arranged behind the forward-leaning portion 11 in the vehicle length direction and is connected to the front bumper lower body 10. The lower leg anti-collision beam 30 is partially disposed in the area where the forward-leaning portion 11 is located and is used to connect to the subframe (not shown). A gap 301 is formed between the portion of the lower leg anti-collision beam 30 located in the area where the forward-leaning portion 11 is located and the forward-leaning portion 11. At least two support brackets 40 are arranged on both sides of the lower leg anti-collision beam 30 in the width direction of the vehicle front structure 100. Each support bracket 40 is disposed outside the gap 301 and is connected to the lower leg anti-collision beam 30 and the lower leg protection bracket 20, respectively. Here, the forward-leaning portion 11 of the lower body 10 of the front bumper specifically refers to the part of the lower body 10 of the front bumper that is inclined from the rear of the vehicle to the front of the vehicle in the length direction of the vehicle, and the user can directly observe the forward-leaning portion 11 in the forward-looking direction of the vehicle.
[0042] As can be seen from the above, by utilizing the connection between the lower leg protection bracket 20 and the lower body 10 of the front bumper, the lower leg anti-collision beam 30 can provide bottom support for the lower body 10 of the front bumper through the support bracket 40 and the lower leg protection bracket 20. This not only meets the modal and strength requirements of the lower body 10 of the front bumper, but also prevents the forward-leaning part 11 of the lower body 140 of the front bumper from colliding with the lower leg anti-collision beam 30 during vehicle operation, thus avoiding abnormal noise caused by the collision of the lower body 10 of the front bumper. In this process, since the assembly of the support bracket 40 does not occupy the gap 301 between the lower leg anti-collision beam 30 and the forward-leaning part 11 of the lower body 10 of the front bumper, the forward-leaning angle of the forward-leaning part 11 can be larger, which can meet the requirement of a large approach angle of the front of the vehicle.
[0043] It should be noted that since the lower leg anti-collision beam 30 is connected and supported by the support bracket 40, the support bracket 40 has the advantage of a short lever arm, providing point-to-point support / tension to the lower front bumper body 10. This ensures that the strength and modal characteristics of the lower front bumper body 10 meet the requirements. In addition, the structural toughness of the support bracket 40 makes it less prone to deformation, ensuring a safe clearance between the lower front bumper body 10 and the lower leg anti-collision beam 30 during dynamic driving. This prevents abnormal noises caused by collisions between the lower front bumper body 10 and the lower leg anti-collision beam 30 and also prevents wear.
[0044] like Figure 1 , Figure 6As shown, the lower leg anti-collision beam 30 includes a lower leg anti-collision crossbar 31 and energy-absorbing boxes 32. Two energy-absorbing boxes 32 are configured, arranged on both sides of the lower leg anti-collision crossbar 31 in the width direction of the vehicle's front structure, and used for connection to the subframe (not shown). Here, the lower leg anti-collision crossbar 31 is positioned above the forward-leaning portion 11 in the vertical direction of the vehicle.
[0045] In one embodiment, the support bracket 40 is screwed to the lower leg anti-collision beam 30 and / or the lower leg protection bracket 20, which facilitates the assembly and connection between the support bracket 40 and the lower leg anti-collision beam 30 and / or the lower leg protection bracket 20. Here, as Figure 2 , Figure 5 and Figure 6 As shown, the support bracket 40 can be connected and fixed to the lower leg anti-collision beam 30 and the lower leg protection bracket 20 using bolts 101. It is understood that in other embodiments, bolt and nut assemblies can also be used to achieve the assembly connection between the support bracket 40 and the lower leg anti-collision beam 30 and / or the lower leg protection bracket 20, or welding can be used to achieve the assembly connection between the support bracket 40 and the lower leg anti-collision beam 30 and / or the lower leg protection bracket 20.
[0046] In one embodiment, the support bracket 40 is configured as a sheet metal part and / or a plastic part.
[0047] like Figure 1 , Figure 5 and Figure 6 As shown, in one embodiment, the support bracket 40 includes a first support bracket 41, the two ends of which are connected to the lower leg anti-collision crossbar 31 and the lower leg protection bracket 20. That is, the lower leg anti-collision crossbar 31 and the lower leg protection bracket 20 are connected and supported by the first support bracket 41. Here, two first support brackets 41 are configured, symmetrically arranged on both sides of the lower leg anti-collision crossbar 31. It is understood that in other embodiments, the number of first support brackets 41 may be one, three, or even more, and the arrangement position of the first support brackets 41 on the lower leg anti-collision crossbar 31 can be specifically set according to the usage requirements, which will not be elaborated here.
[0048] like Figure 5 , Figure 6As shown, the first support bracket 41 includes a first connecting end 411, which is disposed on the side of the lower leg anti-collision crossbar 31 away from the forward tilting portion 11 and connected to the lower leg anti-collision crossbar 31. This ensures that the assembly of the first connecting end 411 on the lower leg anti-collision crossbar 31 does not occupy the gap between the lower leg anti-collision crossbar 31 and the forward tilting portion 11 on the lower front bumper body 10. This allows the tilt angle of the forward tilting portion 11 on the lower front bumper body 10 to be as large as possible to adapt to different vehicle styles; it also facilitates the assembly and connection of the first connecting end 411 on the lower leg anti-collision crossbar 31.
[0049] like Figure 5 As shown, one of the first connecting end 411 and the lower leg anti-collision crossbar 31 has a first positioning hole 311, and the other has a protruding first positioning member 4111. The first positioning member 4111 is inserted into the first positioning hole 311 for assembling and positioning the first connecting end 411 and the lower leg anti-collision crossbar 31. This allows the first connecting end 411 to be positioned and assembled with the lower leg anti-collision crossbar 31 by first using the insertion and engagement between the first positioning member 4111 and the first positioning hole 311. This ensures the accuracy of the assembly position between the first connecting end 411 and the lower leg anti-collision crossbar 31, facilitating subsequent assembly and fixing. Here, the first positioning member 4111 is configured such that a rib is formed on the first connecting end 411, and the first positioning hole 311 is provided on the lower leg anti-collision crossbar 31. It is understood that in other embodiments, the first positioning member may also be provided on the lower leg anti-collision crossbar 31, and the first positioning hole may be provided on the first connecting end 411.
[0050] like Figure 3 , Figure 4 As shown, the first connection portion 201 between the first support bracket 41 and the lower leg protection bracket 20 is independently provided relative to the second connection portion 202 between the lower leg protection bracket 20 and the lower front bumper body 10. This allows the lower leg protection bracket 20 to be assembled and connected independently to the first support bracket 41 and the lower front bumper body 10, and the assembly of the lower leg protection bracket 20 to the first support bracket 41 and the lower front bumper body 10 does not affect each other. Here, the aforementioned first connection portion 201 and second connection portion 202 are portions that cannot be observed by the user.
[0051] It should be noted that, since the front structure 100 of the vehicle uses the support bracket 40 to support the lower body 10 of the front bumper, the second connection part 202 connecting the lower body 10 of the front bumper and the lower leg protection bracket 20 can be moved backward into the vehicle interior to the plane, reducing the problem of the second connection part 202 connecting the lower body 10 of the front bumper and the lower leg protection bracket 20 being exposed in the front view. This makes it impossible for users to easily see the second connection part 202 from the front of the vehicle with the front structure 100, and enhances the refinement of the front structure 100 of the vehicle. Thus, the problem of the bottom mounting point of the lower body 10 of the front bumper being exposed in vehicles with large approach angles can be solved and improved.
[0052] like Figure 1 , Figure 6 As shown, the support bracket 40 includes a second support bracket 42, the two ends of which are connected to the energy-absorbing box 32 and the lower leg protection bracket 20. That is, the energy-absorbing box 32 and the lower leg protection bracket 20 are connected and supported by the second support bracket 42. Here, two second support brackets 42 are configured, with each energy-absorbing box 32 connected to the lower leg protection bracket 20 via one second support bracket 42.
[0053] like Figure 2 , Figure 6 As shown, the second support bracket 42 includes a second connecting end 421, which is disposed on the side of the energy-absorbing box 32 facing the lower leg protection bracket 20 and connected to the energy-absorbing box 32. This satisfies the assembly connection between the second support bracket 42 and the energy-absorbing box 32.
[0054] like Figure 2 As shown, one of the second connecting end 421 and the energy-absorbing box 32 has a second positioning hole 321, and the other has a protruding second positioning member 4211. The second positioning member 4211 is inserted into the second positioning hole 321 for assembling and positioning the second connecting end 421 and the energy-absorbing box 32. This allows the second connecting end 421 to first achieve assembly and positioning with the energy-absorbing box 32 using the insertion and engagement between the second positioning member 4211 and the second positioning hole 321. This ensures the accuracy of the assembly position between the second connecting end 421 and the energy-absorbing box 32, facilitating subsequent assembly and fixation. Here, the second positioning member 4211 is configured with a protruding rib on the second connecting end 421, and the second positioning hole 321 is located on the energy-absorbing box 32. It can be understood that in other embodiments, the second positioning member can also be located on the energy-absorbing box 32, and the second positioning hole can be located on the second connecting end 421.
[0055] It should be noted that the arrangement of multiple support brackets 40 between the lower leg anti-collision beam 30 and the lower leg protection bracket 20 is not limited to the above-described manner. For those skilled in the art, it is possible to arrange support brackets 40 only on the lower leg anti-collision crossbar 31 of the lower leg anti-collision beam 30, or only on the energy absorption box 32 of the lower leg anti-collision beam 30. Alternatively, the number of support brackets 40 may be configured as two, one on the lower leg anti-collision crossbar 31 of the lower leg anti-collision beam 30 and the other on the energy absorption box 32 of the lower leg anti-collision beam 30. These will not be elaborated upon here.
[0056] In addition, this application also provides a vehicle including the aforementioned vehicle front structure 100.
[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0058] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
