Description

Technical Field

[0001] The invention relates to a modification design of automobile parts, in particular to a front wheel cover supporting structure. Background Art

[0002] Vehicle wading condition: The vehicle wading problem mainly studies the situation when the vehicle is driving on a relatively deep water road at a relatively low speed. In this case, the vehicle OEM (Original Equipment Manufacturer) system must be complete and work properly, such as the sealing of the lower body of the tram, the integrity of the battery pack high-voltage system, and the electronic control system. When designing the front of the tram and the bottom guard of the battery pack, the water level and water inflow should be considered in particular. Once the sealing of the lower body fails, it will cause irreversible adverse effects on the tram power system.

[0003] The vehicle wading condition is a conventional condition for evaluating the sealing of the car (electric vehicle) body and lower body (chassis). At present, the lower body layout of electric vehicles is very different from that of traditional fuel vehicles. There is a cavity between the front wheel rear cover and the battery pack of many long-wheelbase electric vehicles. Based on this structural characteristic, under severe wading conditions, the front wheel rear cover is prone to serious deformation, causing the sealing of the lower body to fail. In order to cope with this situation, most OEMs use foam to fill the space or change the layout of the lower body. The filling method has low cost but limited actual application effect. The filler cannot cope with the continuous impact of high-pressure water flow due to cost and material limitations; design changes are generally not adopted due to long cycles and high costs.

[0004] The current wading test conditions adopted by mainstream OEMs are shallow water wading, with vehicle speeds of 10km / h, 20km / h, 30km / h, 40km / h and 60km / h, and water depths of 100mm, 200mm and 300mm. During the test, the flow and distribution of water around key components (front wheel cover fenders, battery pack bottom guard plates) are recorded by cameras, and the deformation of related components is recorded. However, the actual driving scenario of the vehicle may encounter more severe tests of water depth and speed. At that time, the ordinary fender support structure is not enough to cope with the huge deformation under the water pressure, resulting in structural collapse and failure of the battery pack due to water ingress.

[0005] Therefore, there are currently two common problems in vehicle wading conditions. If these two problems are not properly resolved, the sealing performance of the lower body and chassis will fail when subjected to severe water pressure impact, resulting in severe deformation of the vehicle's front wheel rear cover and the bottom guard plate of the battery pack, which in turn causes damage to the battery pack, leading to serious vehicle safety hazards.

[0006] Problem 1: The vehicle's front wheel rear cover does not absorb enough energy. At present, when most models are conducting wading tests, the front wheel rear cover has fewer parts that can participate in energy absorption, which will cause high-pressure water to flow through the wheel after acceleration and violently impact the front wheel rear cover and the battery pack bottom guard plate, causing the connection between the two to tear, resulting in the intrusion of high-pressure water and the deformation of the battery pack bottom guard plate.

[0007] Problem 2: The electric vehicle design process lacks support for the back of the front wheel rear cover. At the same time, due to the difference in layout between electric vehicles and traditional fuel vehicles, the space behind the structure is large, which is prone to deformation risk. Therefore, a reasonable design of lateral support helps to reduce the compression deformation of the front wheel rear cover under wading conditions, while reducing the risk of tearing at the connection between it and the bottom guard plate of the battery pack, better ensuring the sealing of the lower body and the battery pack, thereby improving the safety factor of the electric vehicle battery pack. Summary of the invention

[0008] There are two problems in the prior art:

[0009] Problem 1: The vehicle's front wheel rear cover does not absorb enough energy. At present, when most models are conducting wading tests, the front wheel rear cover has fewer parts that can participate in energy absorption, which will cause high-pressure water to flow through the wheel after acceleration and violently impact the front wheel rear cover and the battery pack bottom guard plate, causing the connection between the two to tear, resulting in the intrusion of high-pressure water and the deformation of the battery pack bottom guard plate.

[0010] Problem 2: Electric vehicles are designed with insufficient support on the back of the front wheel rear cover. Also, due to the differences in layout between electric vehicles and traditional fuel vehicles, there is a large space behind the structure, which makes it prone to deformation risk.

[0011] Based on the above two problems, the present invention proposes a new front wheel cover support structure. The reasonable lateral support design helps to reduce the compressive deformation of the front wheel rear cover when the vehicle is wading, and at the same time reduces the risk of tearing at the connection between it and the bottom guard plate of the battery pack, thereby better ensuring the sealing between the lower body and the battery pack, thereby improving the safety factor of the electric vehicle battery pack.

DETAILED DESCRIPTION

[0028] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0029] In a specific embodiment of the present scheme, a front wheel cover support structure is provided, and the front wheel cover support structure mentioned here is used for installation and fixation with the left mounting bracket assembly and the right mounting bracket assembly; in the structural concept of the present scheme, through the coordinated design of the front wheel rear cover support structure and its isotropic stiffness, it is possible to achieve better energy absorption and support for the front wheel rear cover when the vehicle encounters severe wading conditions, thereby reducing the risk of failure of the connection between the front wheel rear cover and the vehicle's lower bottom guard plate, thereby ensuring the sealing of the vehicle's lower body and the battery pack, and greatly improving the vehicle's wading performance.

[0030] For details, see Figure 1 - Figure 2 In this solution, the front wheel cover support structure provided above includes a bracket shape body 100 and an auxiliary bracket mounting frame 200; wherein, two auxiliary bracket mounting frames 200 are designed, and therefore, the two auxiliary bracket mounting frames 200 are respectively installed and fixed on the left and right sides of the bracket shape body 100.

[0031] It can be understood that the front wheel cover support structure in the present solution is specifically composed of a bracket shaping body 100 and an auxiliary bracket mounting frame 200, wherein the bracket shaping body 100 is located in the middle position, and the auxiliary bracket mounting frame 200 is designed to be two, and the two auxiliary bracket mounting frames 200 are respectively fixed on the left and right sides of the bracket shaping body 100. The front wheel cover support structure mentioned in the present solution is formed through the above structure.

[0032] In a specific embodiment of the present scheme, mounting points 201 are provided at the upper and lower ends of each auxiliary bracket mounting frame 200; the front wheel cover support structure is stably mounted and fixed to the left mounting bracket assembly and the right mounting bracket assembly at the same time through the mounting points 201.

[0033] That is, in this solution, in order to achieve the purpose of improving the connection stability, a mounting point 201 is specially set on the designed auxiliary bracket mounting frame 200, and the mounting point 201 is respectively set at the upper and lower ends of the auxiliary bracket mounting frame 200, thereby achieving the purpose of improving the rigidity and durability.

[0034] Optionally, in a specific embodiment of the present scheme, the structural strength of the mounting point 201 needs to meet the requirements of rigidity and durability in the three directions of X, Y, and Z. At the same time, in the present scheme, the arrangement of the mounting point 201 is determined according to the shape of the front wheel cover, the bottom guard plate of the battery pack and their spatial relationship, and the requirements for the rationality of the shape assembly need to be considered. The rigidity of the mounting point 201 in the X direction in the assembled state must reach 100N / mm, and the support capacity of the front wheel cover in the X direction should be increased as much as possible. It should be noted that the mounting point 201 is the first structural component that contacts the front wheel cover during the wading process. While participating in energy absorption, it can produce a certain structural stability, thereby minimizing the impact deformation of the front wheel cover.

[0035] Therefore, in this solution, a total of five mounting points 201 are designed; by utilizing the five mounting points 201 here, the support capacity of the front wheel cover in the X direction can be increased as much as possible, thereby achieving the purpose of allowing the front wheel cover to produce a certain structural stability while participating in energy absorption, thereby minimizing the impact deformation of the front wheel cover.

[0036] Optionally, in a specific embodiment of the present solution, according to the front wheel cover support structure described above, the auxiliary bracket mounting frame 200 designed here can be made of aluminum alloy and sheet metal.

[0037] Optionally, in a specific embodiment of the present scheme, according to the front wheel cover support structure described above, the cross-section of the bracket shaping body 100 is a "sun" or "H" shaped cross-section structure.

[0038] Specifically, the material of the bracket body 100 can be aluminum alloy and sheet metal. In order to provide sufficient energy absorption, the structure is preferably an arc-shaped cross-section. The aluminum alloy structure usually has a "sun" and "H" shaped cross-section, with a thickness of 2.5 mm and above, which maximizes cost savings while ensuring strength and durability. This structure is fixed to the back of the front wheel rear cover and the front end of the battery pack bottom guard plate by bolts. Under the premise that the layout conditions can be met, the front wheel rear cover bracket is arranged as far forward as possible in the direction of the vehicle's battery pack bottom guard plate, and it is best to keep it consistent with the connection between the front wheel rear cover and the battery pack bottom guard plate.

[0039] In order to facilitate those skilled in the art to further understand the present solution, the specific structures of the support body 100 and the auxiliary support mounting frame 200 are introduced in more detail below.

[0040] Specifically, in a specific embodiment of the present scheme, according to the above-described front wheel cover support structure, the bracket shaping body 100 specifically includes an upper bracket 101, a lower bracket 102 and a connecting frame 103; wherein, the upper bracket 101 and the lower bracket 102 are spaced apart, and the upper bracket 101 and the lower bracket 102 are in a parallel state; the connecting frame 103 is vertically arranged, the upper end of the connecting frame 103 is fixed on the upper bracket 101, and the lower end of the connecting frame 103 is fixed on the lower bracket 102.

[0041] It can be understood that the bracket shape body 100 is specifically composed of three main parts, namely the upper bracket 101, the lower bracket 102 and the connecting frame 103. Through the structural layout, the final bracket shape body 100 becomes a "sun" or "H" shaped section. Through such a design, it has a great promoting effect on ensuring strength and durability and maximizing cost savings.

[0042] The upper bracket 101 is an important part of the bracket body 100. Specifically, in the specific embodiment of the present invention, according to the front wheel cover support structure described above, the two free ends of the upper bracket 101 are respectively set as bending structures 1011. The upper bracket 101 is installed and fixed with the left mounting bracket assembly and the right mounting bracket assembly through the bending structures 1011 at both ends of itself. This is because after the two ends of the upper bracket 101 are bent, a stable mounting surface will be formed at the bending. At this time, the upper bracket 101 can be installed and fixed with the auxiliary bracket mounting frame 200 more stably through the mounting surface here with the cooperation of the hexagonal flange bolts.

[0043] In the specific embodiment of the present solution, the structure of the lower bracket 102 is substantially the same as that of the upper bracket 101. Specifically, the two free ends of the lower bracket 102 are also provided with a bending structure 1021; the lower bracket 102 is installed and fixed with the left mounting bracket assembly and the right mounting bracket assembly through the bending structures 1021 at both ends of itself. This is because after the two ends of the lower bracket 102 are bent, a stable mounting surface will be formed at the bending. At this time, the lower bracket 102 can be installed and fixed with the auxiliary bracket mounting frame 200 more stably through the mounting surface here with the cooperation of the hexagonal flange bolts.

[0044] Therefore, it is not difficult to conclude that in a specific embodiment of the present solution, the upper bracket 101 and the lower bracket 102 are connected and fixed to the auxiliary bracket mounting frame 200 through their respective bending structures.

[0045] Further, in a specific embodiment of the present invention, according to the above-mentioned front wheel housing support structure, the support body 100 is made of aluminum alloy or sheet metal material. By using aluminum alloy or sheet metal material, sufficient energy absorption effect can be ensured, and the cost can be saved to the maximum extent while ensuring strength and durability.

[0046] Further, in a specific embodiment of the present invention, according to the above-mentioned front wheel housing support structure, the thickness of the support molding body 100 is not less than 2.5 mm. By controlling its thickness, it has a great promoting effect on ensuring strength and durability and maximizing cost saving.

[0047] Furthermore, in a specific embodiment of the present scheme, according to the above-mentioned front wheel cover support structure, the auxiliary bracket mounting frame 200 is also designed here. Specifically, the auxiliary bracket mounting frame 200 includes an auxiliary left bracket 210 and an auxiliary right bracket 220; wherein, the auxiliary left bracket 210 has a first bending edge 211, and the bending portion of the bracket shaping body 100 is fixed to the first bending edge 211; the auxiliary right bracket 220 has a second bending edge 221, and the bending portion on the other side of the bracket shaping body 100 is fixed to the second bending edge 221.

[0048] It can be understood that in the present solution, in order to enhance the stability of the entire front wheel cover support structure, bending edges are particularly provided on the auxiliary left bracket 210 and the auxiliary right bracket 220. Specifically, a first bending edge 211 is provided on the auxiliary left bracket 210, and the first bending edge 211 is provided at the edge of the auxiliary left bracket 210 facing the bracket shaping body 100. The first bending edge 211 formed here is fixed to the bending structure in the bracket shaping body 100, which greatly promotes the improvement of stability and the guarantee of connection strength.

[0049] Similarly, in a specific embodiment of the present scheme, a second bending edge 221 is provided on the auxiliary right bracket 220, and the second bending edge 221 here is provided at the edge of the auxiliary right bracket 220 facing the bracket shaping body 100; the second bending edge 221 formed here is fixed with the bending structure in the bracket shaping body 100, which greatly promotes the improvement of stability and the guarantee of the connection strength.

[0050] Therefore, it is not difficult to understand that in this solution, by setting bending edges on both the auxiliary left bracket 210 and the auxiliary right bracket 220, the bending edges are used to correspond to the bending structure in the bracket shape body 100 to fix them; thereby achieving the purpose of ensuring sufficient energy absorption effect and ensuring sufficient connection strength required in this solution.

[0051] Furthermore, in a specific embodiment of the present scheme, according to the above-described front wheel cover support structure, the auxiliary left bracket 210 includes a first bracket body 212 and first support plates 213 arranged at both ends of the first bracket body 212, and the first support plates 213 at both ends are bent in the same direction, and a first installation point is opened on the two first support plates 213.

[0052] That is, in the present solution, in order to ensure that the front wheel cover support structure can be installed and fixed with the left mounting bracket assembly and the right mounting bracket assembly, a first support plate 213 is specially designed in the auxiliary left bracket 210. Specifically, the first support plate 213 is arranged at the upper and lower ends of the first bracket body 212; and the two first support plates 213 are also bent in the same direction at the same time, so that the entire auxiliary left bracket 210 has a frame-type structure. Such a structure has a great protective effect on improving stability and ensuring the strength of the structure; and the first mounting points proposed in the present solution are respectively opened on the plate surface of the first support plate 213 here, so that when the first support plate 213 is used to install and fix with the left mounting bracket assembly and the right mounting bracket assembly, the fixation is completed by using bolts, so that the stability of the connection is guaranteed.

[0053] Furthermore, in a specific embodiment of the present scheme, according to the above-described front wheel cover support structure, the auxiliary right bracket 220 includes a second bracket body 222 and second support plates 223 arranged at both ends of the second bracket body 222, and the bending directions of the second support plates 223 at both ends are opposite, so that the auxiliary right bracket 220 has a Z-shaped structure, and a second installation point is opened on the plate surface of the two second support plates 223.

[0054] That is, in this solution, in order to ensure that the front wheel cover support structure can be installed and fixed with the left mounting bracket assembly and the right mounting bracket assembly, a second support plate 223 is specially designed in the auxiliary right bracket 220. Specifically, the second support plate 223 is arranged at the upper and lower ends of the second bracket body 222. Unlike the first support plate 213, the two second support plates 223 are also bent in opposite directions at the same time, so that the entire auxiliary right bracket 220 is a Z-shaped structure. Such a structure also has a great guarantee effect on improving stability and ensuring the strength of the structure. At the same time, through a special design in this solution, the auxiliary left bracket 210 is a frame-shaped structure and the auxiliary right bracket 220 is a Z-shaped structure. Such a structural design is designed according to specific conditions, determined according to the shape of the front wheel cover, the bottom guard plate of the battery pack and their spatial relationship, and at the same time, the reasonableness of the shape assembly needs to be considered. Through the above structural design, it is greatly promoted to ensure that the rigidity of the bracket mounting point in the X direction reaches 100N / mm in the assembled state, and to increase the support capacity of the front wheel cover in the X direction as much as possible. Therefore, through the design of the above structure, the bracket installation point is the first structural component that contacts the front wheel cover during wading. While participating in energy absorption, it can produce a certain structural stability and minimize the impact deformation of the front wheel cover.

[0055] Specifically, like the first support plate 213, the second mounting points proposed in this solution are respectively opened on the plate surface of the second support plate 223 here, so that when the second support plate 223 is used to install and fix with the left mounting bracket assembly and the right mounting bracket assembly, the fixation is completed by using bolts, thereby ensuring the stability of the connection.

[0056] Furthermore, in a specific embodiment of the present scheme, according to the above-described front wheel cover support structure, reinforcing ribs 230 are provided on both the first bracket body 212 and the second bracket body 222, and the reinforcing ribs 230 here specifically include first reinforcing ribs and second reinforcing ribs, and the first reinforcing ribs are provided on the first bracket body 212 and extend along the first bending edge; the second reinforcing ribs are provided on the second bracket body 222 and extend along the length direction of the second bracket body.

[0057] The purpose of setting the reinforcing rib 230 is that the structure needs to be arranged with a frame of the bracket shape, and transition and overlap according to the installation point. The arrangement of the reinforcing rib 230 can effectively improve the rigidity and durability of the three directions of X, Y, and Z of each installation point of the bracket, thereby ensuring the low deformation of the structure under wading conditions. Therefore, in order to achieve this purpose, reinforcing ribs 230 are specially set on the auxiliary left bracket 210 and the auxiliary right bracket 220 respectively; specifically, a first reinforcing rib is set on the first bracket body 212 in the auxiliary left bracket 210. Because the first bracket body 212 is vertically arranged, the first reinforcing rib here is also vertically arranged, that is, it is designed along the extension direction of the first bracket body 212; similarly, in order to strengthen the stability of the structural strength of the auxiliary right bracket 220, a second reinforcing rib is set on the second bracket body 222 in the auxiliary right bracket 220. Because the second bracket body 222 is vertically arranged, the second reinforcing rib here is also vertically arranged, that is, it is designed to extend along the length direction of the second bracket body 222.

[0058] The vehicle wading condition is one of the working conditions with the highest requirements for structural performance in the current passenger car water management system, and has always been a difficult working condition for the safety development of major OEMs. The patent of this invention can achieve better energy absorption and support for the front wheel rear cover when the vehicle encounters severe wading conditions by coordinating the design of the front wheel rear cover bracket structure and its anisotropic stiffness, thereby reducing the risk of failure of the connection between the front wheel rear cover and the vehicle's lower bottom guard plate, thereby ensuring the sealing of the vehicle's lower body and battery pack, and greatly improving the vehicle's wading performance.
