[0002] To prevent damage to the vehicle's internal structure caused by the impact force of the vehicle's hood on the vehicle body during closing, a hood buffer block (hereinafter referred to as a buffer block) is typically installed in the vehicle to support the hood. With the increasing demand for safety performance in the automotive industry, it is expected that the hood will be able to reduce the damage to pedestrians in the event of a collision with a vehicle.

DETAILED DESCRIPTION

[0031] The following is an exemplary description of the embodiments of the present application in conjunction with the accompanying drawings. It should be understood that there are many ways to implement the present application and it should not be construed as being limited to the embodiments described here. The embodiments described here are only for a more thorough and clear understanding of the present application.

[0032] When closing a vehicle's hood, it can have a significant impact on the vehicle's body. To prevent damage to the vehicle's internal structure caused by the impact, a hood buffer (referred to as a buffer) is typically installed under the hood. As a possible implementation, the buffer is typically mounted within the hood's sheet metal.

[0033] The buffer block supports the hood when it is closed. Furthermore, when the hood is closed normally (i.e., subjected to an impact force within the rated threshold), the buffer block compresses by 2-3mm under the impact force of the hood, absorbing the impact force and preventing a significant impact on the vehicle body.

[0034] With the increasing demand for safety performance in the automotive industry, it is hoped that the hood can reduce damage to pedestrians in the event of a collision. Therefore, a bracket can be provided specifically for the bump stop. This bracket can also be called a bump stop mounting bracket. As a possible implementation, the bracket can be located between the hood sheet metal and the bump stop, and the bracket can be fixed to the hood sheet metal.

[0035] The bracket member can enable the buffer block to contact a front position of the vehicle's front cabin (e.g., near the vehicle's headlights or near the vehicle's front bumper) when the hood is closed, thereby supporting the vehicle's front hood. Furthermore, if the hood is subjected to an impact force exceeding a rated threshold when the hood is closed, the bracket member can automatically be damaged by the impact force, thereby absorbing the impact force exceeding the threshold when the hood is closed, allowing the hood to move a greater distance in the closing direction, thereby protecting pedestrians.

[0036] In view of this, the bracket of the buffer block needs to have a certain rigidity to support the normal closing of the engine hood. At the same time, the bracket of the buffer block is also required to allow the engine hood to have a certain deformation and energy absorption ability when it is subjected to an impact force exceeding the rated threshold, so as to avoid causing excessive harm to pedestrians when a vehicle collides with pedestrians, and provide more protection for pedestrians.

[0037] As previously mentioned, the bracket components used in related art are typically single-piece brackets connected to the sheet metal of the hood. To ensure that this single-piece bracket meets both the aforementioned stiffness requirements and the impact force absorption requirements, it has dimensional requirements in the direction of the hood opening or closing. Due to these dimensional requirements, single-piece brackets used in related art can only be installed at the front end of the hood. This is because only the front end of the hood, corresponding to the position in the vehicle's front compartment, has parts located relatively high for contact with the buffer block. This ensures that the single-piece bracket, while meeting the dimensional requirements, can also contact relevant parts in the vehicle's front compartment when the hood is closed, thereby providing effective support.

[0038] It should be noted that the opening direction of the hood can be referred to as the first direction, which can be understood as the direction in which the hood moves upward when the hood is opened, that is, the first direction is perpendicular to the bottom plate of the vehicle's front cabin and points to the hood. The closing direction of the hood can be referred to as the second direction, which can be understood as the direction in which the hood moves downward when the hood is closed, that is, the second direction is perpendicular to the bottom plate of the vehicle's front cabin and points to the bottom plate. The second direction is the opposite direction to the first direction. The first direction is, for example, the following Figures 1-9 The second direction is, for example, the Z+ direction in the following Figures 1-9The Z-direction.

[0039] However, this results in a relatively limited placement of the bracket and buffer, which can only be located at the front end of the hood. This necessitates reserving space for the buffer at the front end of the vehicle's front compartment when designing the vehicle model, preventing improvements to the hood front end and the corresponding front end of the vehicle's front compartment. This, in turn, hinders vehicle model diversity and improves space utilization.

[0040] In view of this, an embodiment of the present application provides a bracket assembly for a hood buffer block and a vehicle using the bracket assembly, aiming to set the mounting structure of the hood buffer block as a bracket assembly formed by a first bracket connected to a part to be connected in a front cabin of the vehicle and a second bracket connected to the first bracket, wherein the first bracket has a top plate separated from the part to be connected in the front cabin of the vehicle by a first distance in a first direction, the second bracket has a base portion and a protrusion portion, the base portion has a support plate separated from the top plate by a second distance in the first direction, the protrusion portion protrudes from the support plate along the first direction and the protrusion portion is connected to the first collapse portion.

[0041] Because the base portion includes a first constriction connected to the raised portion, the second bracket allows the hood to be damaged at the first constriction when subjected to an impact force exceeding a rated threshold, thereby providing a certain degree of deformation and energy absorption, thereby providing pedestrian protection. Furthermore, by adding the first bracket and providing the second bracket with a stepped structure comprising a base portion and a raised portion, the bracket assembly ensures sufficient support for the hood while increasing its size in the direction of hood opening. This allows the bracket assembly to be installed on any desired connection within the vehicle's front cabin, significantly facilitating vehicle model diversity and improving space utilization.

[0042] The following combination Figures 1-9 , a detailed description is given of the vehicle and the bracket assembly 20 of the engine hood buffer block in the vehicle in the embodiment of the present application.

[0043] It should be noted that the vehicle in the embodiments of the present application may refer to a large car, a small car, a special-purpose vehicle, etc. For example, based on the vehicle model, the vehicle in the embodiments of the present application may be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other vehicle models. A vehicle generally has wheels, a power source, and a transmission system arranged between the wheels and the power source. The transmission system can transmit power provided by the power source to the wheels, causing the wheels to rotate, thereby driving the vehicle.

[0044] It should be noted that in the embodiments of this application, the type of vehicle power source is not limited. For example, for a fuel-powered vehicle, the power source may refer to a gasoline engine, a diesel engine, or other fuel-powered 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; and for a vehicle powered by other means, the power source may refer to a device that generates power.

[0045] like Figure 1 As shown, the vehicle may include a hood ( Figures 1-9 (not shown), the part to be connected 10, the bracket assembly 20 and the buffer block 50.

[0046] The hood is located above the front cabin of the vehicle and is used to close the front cabin of the vehicle. In some embodiments, a sheet metal part may be provided on the side of the hood facing the front cabin of the vehicle, and a threaded hole may be provided on the sheet metal part for installing a buffer block 50.

[0047] The part to be connected 10 is a part located in the front cabin of the vehicle. In some embodiments, ( Figures 1-9 (not shown) The component to be connected 10 can be a component located in the middle of the front cabin of the vehicle or a component located at any position between the front end and the middle of the front cabin of the vehicle. Further, the component to be connected 10 can be a component that can span the left and right ends of the front cabin of the vehicle. For example, Figure 8 and Figure 9 As shown, the part to be connected 10 can be a water tank upper crossbeam. For another example, the part to be connected 10 can be a wiper installation assembly.

[0048] The bracket assembly 20 includes a first bracket 30 and a second bracket 40 , wherein the bracket assembly 20 is mounted on the to-be-connected member 10 via the first bracket 30 and the first bracket 30 has a mounting hole 32 , through which the second bracket 40 can be connected to the first bracket 30 .

[0049] The first bracket 30 is fixedly connected to the member to be connected 10. For example, the first bracket 30 can be welded, riveted, or screwed to the member to be connected 10. The first bracket 30 is formed as a support frame below the second bracket 40 and includes a top plate 31 spaced a first distance h1 from the member to be connected 10 in a first direction. The top plate 31 can be positioned toward the engine hood and has a mounting hole 32 formed therein.

[0050] The embodiment of the present application does not specifically limit the material of the first bracket 30. For example, the first bracket 30 can be made of a material with good rigidity, such as a metal part. As an example, the first bracket 30 can be a sheet metal part or a die-cast part.

[0051] In some embodiments, as Figure 1-Figure 3 As shown, part of the top plate 31 may be in a suspended state, that is, part of the top plate 31 may have no support points fixed to the part to be connected 10. For example, the first bracket 30 also includes a first side plate 33 and a second side plate 34 respectively connected to the two ends of the top plate 31, and the first side plate 33 and the second side plate 34 extend from the top plate 31 toward the part to be connected 10 to form two legs respectively located at the two ends of the top plate 31, and the first side plate 33 and the second side plate 34 are both fixedly connected to the part to be connected 10. Except for the two ends of the top plate 31, there is no support point connected to the part to be connected 10 below the top plate 31, that is, the first side plate 33, the second side plate 34 and the top plate 31 are constructed in an "X"-shaped structure, which allows the first bracket 30 to be formed as a suspended support frame. Therefore, the first bracket 30 can also be called a suspended mounting bracket. By configuring the first bracket 30 as a suspended mounting bracket, when the impact force on the engine hood is too large, the first bracket 30 can also have the ability to deform to absorb the impact force transmitted to the first bracket 30 through the buffer block 50 .

[0052] Combine Figure 1 and Figure 4-Figure 7 As shown, the second bracket 40 is a convex structure (ie, a stepped structure) and the second bracket 40 is located on the top plate 31 and connected to the mounting hole 32 on the top plate 31. Figure 1 The second bracket 40 includes a base portion 41 and a raised portion 42. The base portion 41 is configured as a bottom support structure for the raised portion 42, and the horizontal dimension of the outer wall 411 of the base portion 41 is larger than the horizontal dimension of the outer wall 421 of the raised portion 42, so that the base portion 41 forms a "convex" lower half and the raised portion 42 forms a "convex" upper half.

[0053] The present embodiment does not impose any specific restrictions on the material of the second bracket 40, as long as the second bracket 40 can provide the necessary rigidity for the buffer block 50 and can self-destruct when the impact force exceeds a rated threshold. For example, the second bracket 40 can be a one-piece plastic part. As an example, the second bracket 40 can be a plastic part manufactured by 3D printing, injection molding, or machining.

[0054] See Figure 4-Figure 7 The bottom end of the base portion 41 is provided with a mounting portion 412, through which the second bracket 40 is detachably connected to the mounting hole 32 on the top plate 31. The base portion 41 includes a support plate 413 spaced apart from the top plate 31 by a second distance h2 in a first direction. The support plate 413 is provided with a first constricted portion 414.

[0055] In some embodiments, as Figure 5As shown, the first constriction 414 can be a breakable component 415 on the support plate 413. The area where the breakable component 415 is located is a weakened zone of the support plate 413. The breakable component 415 can be formed, for example, by a notch 416 or a recess in the weakened zone. In other words, the weakened zone can have a notch 416 or a recess, so that the weakened zone is formed into the breakable component 415, thereby forming the first constriction 414. The strength and stiffness of the weakened zone of the support plate 413 are less than the stiffness and strength of the non-weakened zone of the support plate 413.

[0056] In some embodiments, as Figure 1-Figure 2 As shown, the support plate 413 and the top plate 31 are both in a horizontal state, that is, the support plate 413 and the top plate 31 can be horizontal plates, that is, the support plate 413 and the top plate 31 are parallel to the ground.

[0057] The raised portion 42 is seated on the support plate 413 and is formed into a structure that protrudes from the support plate 413 in the first direction. The raised portion 42 extends a third distance h3 in the first direction. The top end 422 of the raised portion 42 is connected to or in contact with the buffer block 50, and the bottom end 423 of the raised portion 42 is connected to the first collapsed portion 414.

[0058] The buffer block 50 is located between the hood and the raised portion 42. When the hood is closed, the buffer block 50 can transfer the impact force of the hood on the vehicle body to the raised portion 42 that is in contact with or connected to it. The buffer block 50 can be cylindrical and have external threads 51 on its outer wall. When the hood is closed, the ends of the buffer block 50 can be connected to both the hood and the raised portion 42 to transfer the impact force of the hood on the vehicle body to the raised portion 42.

[0059] In some embodiments, the external thread 51 of the buffer block 50 is connected to the threaded hole in the sheet metal of the above-mentioned engine hood. As the engine hood is closed, the buffer block 50 can contact and connect with the protrusion 42, thereby transmitting the impact force to the protrusion 42.

[0060] In other embodiments, the protrusion 42 is provided with a threaded hole (with 1- Figure 9 (not shown), the external thread 51 of the buffer block 50 is connected to the threaded hole on the protrusion 42. When the engine hood is closed, the engine hood can be in contact and connected with the buffer block 50 connected to the protrusion 42, so that the engine hood transfers the impact force to the protrusion 42 through the buffer block 50.

[0061] Through the above arrangement, when the hood is normally closed, the bracket assembly 20 can provide sufficient rigidity and strength for the buffer block 50 to ensure that the buffer block 50 can support the hood to avoid damage to components in the vehicle body caused by the normal impact force of the hood; when the hood encounters an impact force exceeding the rated threshold when closing, the buffer block 50 can transmit the impact force to the protrusion 42, causing the protrusion 42 to break at the first crush portion 414, so that the protrusion 42 can fall from the first crush portion 414 into the front cabin of the vehicle, so that the hood can move a greater distance in the closing direction of the hood, thereby protecting pedestrians.

[0062] In addition, since the bracket assembly 20 is composed of a first bracket 30 and a second bracket 40 formed into a stepped structure, its size in the opening direction of the engine hood can be formed by superimposing three sizes (the above-mentioned h1, h2 and h3), thereby increasing the size of the bracket assembly 20 in the opening direction of the engine hood, so that the bracket assembly 20 can be installed on any part to be connected 10 in the front cabin of the vehicle, which is very beneficial to the diversity of vehicle model changes and the improvement of space utilization.

[0063] The embodiment of the present application does not specifically limit the shape of the protrusion 42, as long as the protrusion 42 can enable the buffer block 50 to transfer the impact force of the engine hood to the protrusion 42 when the engine hood is closed. For example, the protrusion 42 is formed into a cylinder, a cube, or a waist-shaped cylinder.

[0064] As mentioned above, the bracket assembly 20 can be installed at any position in the front cabin of the vehicle. When the arbitrary position is a position between the front position and the middle position or the middle position in the front cabin of the vehicle, the engine hood corresponding to the installation position of the buffer block 50 will most likely be an inclined plane inclined to the horizontal plane. At this time, if the engine hood is in a closed state, the impact force of the engine hood on the buffer block 50 will be perpendicular to the inclined plane. Correspondingly, the extension direction of the buffer block 50 should also be perpendicular to the inclined plane to effectively transmit the impact force.

[0065] In order to further ensure that the buffer block 50 can effectively transfer the impact force generated by the engine hood to the protrusion 42, in some embodiments, such as Figure 1 As shown, the raised portion 42 includes a first end surface 424 facing the hood. When the hood is closed, the buffer block 50 contacts or connects to the first end surface 424. The first end surface 424 is an inclined surface that forms a specified angle with the horizontal support plate 413. The specified angle is the inclination angle of the hood relative to the horizontal plane corresponding to the installation position of the buffer block 50.

[0066] As previously mentioned, the support plate 413 has a weakened area and a non-weakened area. The weakened area of the support plate 413 is formed as a first collapsed portion 414, and the protrusion 42 is connected to the first collapsed portion 414. It can be seen that the two ends of the weakened area of the support plate 413 are respectively connected to the protrusion 42 and the non-weakened area. The embodiment of the present application does not specifically limit the shape of the weakened area. As an implementation method, the weakened area can be the shape of the outer wall 421 surrounding the protrusion 42. For example, the weakened area can be square, circular, or polygonal in shape. Preferably, the shape of the weakened area is configured to be consistent with the shape of the outer wall 421 of the protrusion 42.

[0067] For example, the outer wall 421 of the protrusion 42 is formed into a first waist shape, such as Figure 5 As shown, the weakened area can be a second kidney-shaped shape surrounding the outer wall 421 of the protrusion 42. The second kidney-shaped shape is a similar shape with larger dimensions than the first kidney-shaped shape. Specifically, the weakened area can be an area provided with multiple discontinuous notches 416 or recessed portions surrounding the outer wall 421 of the protrusion 42. These multiple discontinuous notches 416 or recessed portions have a second kidney-shaped shape. This embodiment of the application does not specifically limit the number of notches 416 within the weakened area. For example, the number of notches 416 can be 3-6.

[0068] In some embodiments, such as 6 and Figure 7 As shown, the raised portion 42 can be formed into a shell-like structure with a hollow structure. That is, the inner wall 425 of the raised portion 42 forms a first accommodating cavity S1, which is a hollow structure. Specifically, the inner wall 425 of the raised portion 42 includes a first inner wall 4251 located at the top of the raised portion 42 and a second inner wall 4252 surrounding the first inner wall 4251. The first inner wall 4251 and the second inner wall 4252 together surround and form the accommodating cavity.

[0069] By configuring the protrusion 42 as a shell-like structure, the rigidity of the protrusion 42 can be ensured while reducing the weight of the second bracket 40 , thereby ensuring the support requirement of the first bracket 30 for the second bracket 40 .

[0070] In order to further ensure that the protrusion 42 formed into a shell-like structure can have sufficient rigidity so as to withstand sufficient impact force. Figure 5-Figure 7 As shown, a reinforcing rib 426 connected to the inner wall 425 of the protruding portion 42 is provided in the first accommodating cavity S1.

[0071] The embodiment of the present application does not impose any specific limitation on the number and location of the reinforcing ribs 426 , as long as the reinforcing ribs 426 are located in the accommodating cavity in the raised portion 42 and connected to the inner wall.

[0072] As a way to implement Figure 5-Figure 7As shown, the reinforcing rib 426 includes a first reinforcing rib 4261 and a second reinforcing rib 4262. The first reinforcing rib 4261 is located on the first inner wall 4251 and is annular. The second reinforcing rib 4262 is located on the second inner wall 4252 and extends vertically along the second inner wall 4252. The second reinforcing rib 4262 is also connected to the annular outer wall of the first reinforcing rib 4261. Preferably, the annular shape of the first reinforcing rib 4261 is similar to the annular shape of the outer wall 421 of the raised portion 42.

[0073] Through this arrangement, the strength and rigidity of the shell-like raised portion 42 can be enhanced in all directions. In addition, the weight of the raised portion 42 can be made lighter, thereby ensuring the stability of the support of the second bracket 40 to the first bracket 30.

[0074] In some embodiments, as Figure 5-Figure 7 As shown, the base portion 41 can be formed into a shell-like structure with a hollow structure. That is, the inner wall 417 of the base portion 41 forms the second accommodating cavity S2, which is a hollow structure. Specifically, the inner wall 417 of the base portion 41 includes a third inner wall 4171 and a fourth inner wall 4172 surrounding the third inner wall 4171. The third inner wall 4171 is the wall of the support plate 413 facing the first bracket 30. The third inner wall 4171 and the fourth inner wall 4172 together enclose the second accommodating cavity S2.

[0075] By providing the base portion 41 with a shell-like structure, the rigidity of the base portion 41 can be ensured while reducing the weight of the second bracket 40, thereby ensuring the support requirements of the first bracket 30 for the second bracket 40. In addition, providing the base portion 41 with a shell-like structure also facilitates the installation of the mounting portion 412 in the mounting hole 32.

[0076] In order to further ensure that the base portion 41 formed into a shell-like structure can have sufficient rigidity so as to withstand sufficient impact force. In some embodiments, a reinforcing rib 418 is provided in the second accommodating cavity S2. Preferably, the reinforcing rib 418 in the second accommodating cavity S2 is connected to both the inner wall 417 of the base portion 41 and the mounting portion 412, thereby enhancing the overall rigidity and strength of the base portion 41 while also strengthening the connection strength of the mounting portion 412. Specifically, as shown in the figure, the reinforcing rib 418 can extend from the third inner wall 4171 along the up-down direction of the fourth inner wall 4172 to a partial or complete connection with the inner wall of the mounting portion 412.

[0077] As mentioned above, the bottom end of the base portion 41 may be provided with a mounting portion 412, and the base portion 41 is connected to the mounting hole 32 on the first bracket 30 through the mounting portion 412. In order to facilitate the connection or removal of the base portion 41 and the first bracket 30, in some embodiments, such as Figure 6and Figure 7 As shown, the base portion 41 has a second end face 419 facing the first bracket 30, and the mounting portion 412 is formed as a snap-fit pin extending from the second end face 419 toward the second direction. The mounting hole 32 on the first bracket 30 is connected to the base portion 41 by snapping with the snap-fit pin on the base portion 41.

[0078] By providing the snap pins to realize the connection between the first bracket 30 and the second bracket 40 through snap connection, the assembly and disassembly of the first bracket 30 is more convenient and the requirement of repeated disassembly can be met.

[0079] To further enhance the pedestrian protection provided by the bracket assembly 20, in some embodiments, the base portion 41 is further provided with a plurality of support legs 420 extending from the second end surface 419 in a second direction. Each of the plurality of support legs 420 has the same extension length, and the extension length of each support leg 420 is less than the extension length of the engaging leg. When the engaging leg is engaged with the mounting hole 32, the plurality of support legs 420 are in contact with the top plate 31. The plurality of support legs 420 can be spaced and evenly arranged on the second end surface 419, and the plurality of support legs 420 and the engaging leg together form a second constriction.

[0080] The second collapsed portion can be understood as a weakened area at the bottom of the base portion 41. Due to the presence of the multiple support legs 420 and the engaging legs, the bottom of the base portion 41 forms a discontinuous contact with the first bracket 30 (i.e., partially in contact and partially out of contact, with the contact and non-contact areas interlaced and spaced apart), thereby forming a weakened area at the bottom of the base portion 41.

[0081] Through this arrangement, when the impact force on the engine hood is greater, the impact force can be absorbed not only by the protrusion 42 breaking from the first crushed portion 414, but also by the base portion 41 breaking from the second crushed portion. Therefore, this arrangement can form a stepped impact force absorption performance, providing further protection for pedestrians.

[0082] As mentioned above, the member to be connected 10 can be a member that can span the left and right ends of the front cabin of the vehicle. Figure 8-Figure 9 As shown, the part to be connected 10 can be the upper cross beam of the water tank. In order to ensure that when the hood is normally closed, the bracket assembly 20 can cooperate with the buffer block 50 to provide stable support for the hood. In some embodiments, such as Figure 8-Figure 9 As shown, the bracket assembly 20 includes a first bracket assembly 210 and a second bracket assembly 220 symmetrically arranged in the left and right directions of the front cabin of the vehicle. Among them, the first bracket 30 of the first bracket assembly 210 and the first bracket 30 of the second bracket assembly 220 are respectively fixedly connected to the two ends of the water tank upper crossbeam.

[0083] The bracket assembly 20 of the embodiment of the present application enables flexible assembly of the bracket assembly 20 and the component to be connected 10. In this application, flexible assembly can be understood as the flexible assembly of the bracket assembly 20 and the component to be connected 10. For example, the component to be connected 10 can be first fixedly installed in the front compartment and then the bracket assembly 20 can be installed on the component to be connected 10. For another example, the bracket assembly 20 can be first installed on the component to be connected 10 and then the component to be connected 10 can be fixedly installed in the front compartment.
