[0045] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0046] like Figure 2-Figure 7 As shown, an embodiment of the present application provides a frame structure suitable for the installation of a vacuum pump assembly 6, in particular suitable for a brake vacuum pump assembly 6, the frame structure comprising a front longitudinal beam, an energy absorption box 1 and a mounting bracket 2; the front longitudinal beam extends along the front-to-rear direction of the frame structure; the energy absorption box 1 is arranged on the front side of the front longitudinal beam, and a pump arrangement area is provided in the space beside the energy absorption box 1, and taking the left front side of the frame structure as an example, the pump arrangement area is located in the space in front of the left front wheel 8 and on the left side of the energy absorption box 1; the mounting bracket 2 is connected to the front longitudinal beam and is located beside the front longitudinal beam and / or the energy absorption box 1, that is, the mounting bracket 2 is located beside the front longitudinal beam, or the mounting bracket 2 is located beside the energy absorption box 1, or the mounting bracket 2 is located beside the connection between the front longitudinal beam and the energy absorption box 1, and the mounting bracket 2 is used to install the vacuum pump assembly 6 and make the vacuum pump assembly 6 located in the pump arrangement area.

[0047] Based on the layout and installation requirements of the vacuum pump assembly 6, such as being as close to the brake booster as possible, having good ventilation and cooling conditions, being easy to maintain and replace, and controlling noise, the applicant, after an in-depth review of the above content and combining the actual structure and space of the vehicle model, chooses to use the space beside the energy absorption box 1 to arrange the vacuum pump assembly 6, that is, as a pump arrangement area, and sets a mounting bracket 2 connected to the front longitudinal beam at an appropriate position, so that the vacuum pump assembly 6 can be located in the preset pump arrangement area after being installed on the mounting bracket 2. With such a configuration, the installation of the vacuum pump assembly 6 is more flexible and convenient, and is no longer susceptible to the outer envelope restriction of the wheel 8. In addition, the pump arrangement area is an area with a certain degree of openness, which not only ensures that the vacuum pump assembly 6 is easy to maintain and replace, but also that the pump arrangement area is a location with sufficient air circulation, providing good ventilation and cooling conditions for the vacuum pump assembly 6, avoiding overheating of the vacuum pump assembly 6, and solving the problem of difficulty in reasonably arranging the brake vacuum pump in the vehicle in the prior art.

[0048] It should be noted that, with the vehicle body as a reference, a division in the front and rear, left and right, and up and down directions is naturally formed. In the present application, the distinction between the front and rear sides of each structure is consistent with the front and rear distinction of the frame structure, and the distinction between the left and right sides is consistent with the left and right distinction of the frame structure. The side refers to the two sides in the left and right direction, that is, the side refers to the left side or the right side.

[0049] In some specific embodiments, the front longitudinal beam includes a front longitudinal beam body 3 and a front longitudinal beam end plate 4; the front longitudinal beam end plate 4 is connected to the front side of the front longitudinal beam body 3; wherein the energy absorption box 1 is connected to the front longitudinal beam end plate 4, and the mounting bracket 2 is connected to the front longitudinal beam end plate 4. That is, the energy absorption box 1, the front longitudinal beam end plate 4 and the front longitudinal beam body 3 are sequentially connected along the length direction of the frame structure. The front side of the mounting bracket 2 becomes the connection side of the vacuum pump assembly 6, and the mounting bracket 2 can be firmly connected to the front longitudinal beam end plate 4 by fastening components or welding.

[0050] With such arrangement, on the one hand, the mounting bracket 2 is arranged in the connection area between the energy absorption box 1 and the front longitudinal beam, and the front longitudinal beam end plate 4 provides a reliable connection basis for the mounting bracket 2; on the other hand, the front longitudinal beam end plate 4 is composed of the existing structure of the frame structure. When the mounting bracket 2 is designed as an optional accessory, the flexibility of the connection process can be improved. In a vehicle model that does not need a brake vacuum pump, the mounting bracket 2 can be directly cancelled without affecting the welding relationship of other components. It has integration and compatibility with a variety of vehicle models and can be assembled as needed according to configuration differences, making the frame structure provided by the present application platform-based.

[0051] The front longitudinal beam end plate 4 provided in the present application has a structural design different from that of the existing conventional front longitudinal beam end plate 4. In some preferred embodiments, the front longitudinal beam end plate 4 includes an end plate main body portion 401 and an additional portion 402, and the end plate main body portion 401 and the additional portion 402 are an integrated structure; the end plate main body portion 401 is the main part of the front longitudinal beam end plate 4, and the front longitudinal beam main body 3 and the energy absorption box 1 are both connected to the end plate main body portion 401; the additional portion 402 protrudes from the end plate main body portion 401 to the side of the front longitudinal beam, and the mounting bracket 2 is connected to the additional portion 402.

[0052] In this arrangement, the additional portion 402 is a local widening design in the left and right directions based on the end plate main body portion 401, so that the front longitudinal beam end plate 4 has the function of partitioned connection. The additional portion 402 provides a clear installation position with a certain attachment area for the installation bracket 2, which not only facilitates the connection process, but also is beneficial to the stability after connection.

[0053] Furthermore, in some preferred embodiments, the mounting bracket 2 is a plate extending in the left-right direction of the frame structure; the frame structure further includes a mounting support plate 5, which is connected between the mounting bracket 2 and the front longitudinal beam body 3, so that a triangular structure is formed between the mounting bracket 2, the mounting support plate 5 and the front longitudinal beam body 3. That is, the mounting support plate 5 is located at the rear side of the mounting bracket 2 and beside the front longitudinal beam body 3.

[0054] With such an arrangement, the structural design is simple, a large layout space is saved, the lightweight effect is good, and the mold development cost is low; at the same time, on the basis of the simple structure of the mounting bracket 2, the mounting support plate 5 is installed to supplement the assembly stability to prevent the problem of insufficient rigidity, and can meet the requirements of the vacuum pump assembly 6 for the mounting structure strength and NVH (Noise, Vibration and Harshness) properties.

[0055] Moreover, when the mounting bracket 2 is designed as an optional part, the mounting support plate 5 is also an optional part. In a vehicle type that does not need a brake vacuum pump, the mounting bracket 2 and the mounting support plate 5 can be directly eliminated without affecting the welding relationship of other components. It has integration and compatibility with a variety of vehicle types and can be assembled on demand according to configuration differences, making the frame structure provided in this application platform-based.

[0056] It should be noted that the mounting support plate 5 can be welded and assembled through a two-way welding connection process.

[0057] In combination, by adding a connection portion to the front longitudinal beam end plate 4 and welding it to the mounting bracket 2, and at the same time connecting the mounting support plate 5 to the front longitudinal beam body 3 through a double-welding connection process, the flexibility of the connection process can be improved, and it is convenient to realize the standardization and platformization of the frame structure. That is, in a vehicle model that does not require a brake vacuum pump, the brake mounting bracket 2 and the mounting support plate 5 can be directly eliminated without affecting the welding relationship of other components.

[0058] For example, depending on the vehicle configuration, fuel CVT vehicles require a brake vacuum pump, while pure electric and hybrid vehicles use an electronic vacuum pump that is integrated on the ESC and does not require a brake vacuum pump. In pure electric and hybrid vehicles that do not require a brake vacuum pump, the frame structure can directly eliminate the brake vacuum pump mounting bracket 2 and mounting support plate 5, without affecting other components and installation processes.

[0059] Based on the above-mentioned design of the front longitudinal beam end plate 4, in some preferred embodiments, the upper edge and the lower edge of the end plate body 401 are inclined toward the additional portion 402, that is, the left side height and the right side height of the front longitudinal beam end plate 4 are different. Figure 5 In the perspective of the figure, the additional part 402 is located on the left side of the end plate body 401. Since the upper edge and the lower edge of the end plate body 401 are inclined toward the additional part 402, the height of the left side of the end plate body 401 is smaller than the height of the right side. In this way, since the left side where the additional part 402 is located has a smaller height dimension in the longitudinal direction of the left and right sides of the end plate body 401, the yield strength of the material will increase as the size decreases, so the small size on the left side is less likely to yield under the same stress, which has the effect of strengthening the strength of the additional part 402 and improving the load-bearing capacity of the front longitudinal beam end plate 4 to the vacuum pump assembly 6. After simulation analysis, testing and verification, the end plate body 401 is designed in this form, and the mechanical performance is better.

[0060] In some other preferred embodiments, the front longitudinal beam end plate 4 further includes a reinforcement portion 403 protruding from the end plate body portion 401 to the side of the front longitudinal beam, and the reinforcement portion 403 is located on at least one of the upper and lower sides of the additional portion 402. With such a configuration, after simulation analysis, testing and verification, the end plate body portion 401 is designed to be different from the existing conventional front longitudinal beam end plate 4 in a special-shaped form, which reduces the protrusion of the additional portion 402 to a certain extent, has better mechanical performance, forms a strength reinforcement effect on the additional portion 402, and improves the load-bearing capacity of the front longitudinal beam end plate 4 for the vacuum pump assembly 6.

[0061] Based on the aforementioned embodiment that the mounting bracket 2 is a plate extending in the left-right direction of the vehicle frame structure, the mounting support plate 5 is connected between the mounting bracket 2 and the front longitudinal beam body 3, so as to form a triangular structure between the mounting bracket 2, the mounting support plate 5 and the front longitudinal beam body 3, in some specific embodiments, the mounting support plate 5 is a strip-shaped plate, and the mounting support plate 5 includes a support plate body 501, a first connecting portion 502 and a second connecting portion 503; the first connecting portion 502 and the second connecting portion 503 are respectively located at both ends of the support plate body 501 and are both folded relative to the support plate body 501, the first connecting portion 502 is in surface contact and connection with the mounting bracket 2, and the second connecting portion 503 is in surface contact and connection with the front longitudinal beam body 3. Exemplarily, the first connecting portion 502 of the mounting support plate 5 is connected to the mounting bracket 2 through a fastening assembly, and the second connecting portion 503 of the mounting support plate 5 is connected to the front longitudinal beam body 3 through a fastening assembly and a two-sealing welding process.

[0062] In some other specific embodiments, the thickness of the mounting support plate 5 is 0.9 mm-2 mm, including the end value of both ends. In this way, after ensuring the requirements of collision safety, installation strength and other properties, through structural optimization and material selection, on the basis of ensuring the property requirements, the lightweight requirements of the frame structure are fully considered, and combined with the conclusions of simulation analysis, the thickness of the mounting support plate 5 can be reduced to 1 mm, and the structure is optimized to achieve the effect of reducing cost and weight.

[0063] It should be noted that the front longitudinal beam body 3 includes a front longitudinal beam outer plate and a front longitudinal beam inner plate, and the aforementioned connection with the front longitudinal beam body 3 is specifically connected to the front longitudinal beam outer plate. The structure that needs to be screwed by the fastening assembly is provided with corresponding mounting holes, which will not be described in detail herein.

[0064] Based on the above frame structure, the embodiment of the present application further provides a vehicle, which includes a vacuum pump assembly 6 and the above frame structure. The vacuum pump assembly 6 is connected to the mounting bracket 2 and is located in the pump arrangement area. The vacuum pump assembly 6 includes a pump body and a pump frame and other structures. The pump body is fixed on the pump frame, and the pump frame is assembled and connected to the mounting bracket 2 through a fastening assembly. Since the vehicle has the above frame structure, the beneficial effects of the vehicle brought by the frame structure can be found in the above content and will not be repeated here.

[0065] Furthermore, in some specific embodiments, the frame structure further includes an anti-collision beam 7 located at the front side of the energy absorption box 1; the vacuum pump assembly 6 is located at the side of the energy absorption box 1 close to the wheel 8 of the vehicle, and the vacuum pump assembly 6 is located at the rear side of the anti-collision beam 7 and at the front side of the wheel 8. For example, for the left front part of the frame structure, the pump arrangement area exists in the space between the left side of the energy absorption box 1, the rear side of the anti-collision beam 7 and the front side of the wheel 8, that is, the installation position of the vacuum pump assembly 6 is located, which cleverly utilizes the idle open area in the frame structure.

[0066] In some preferred embodiments, in order to ensure that the collapse and deformation capabilities of the anti-collision beam 7 and the energy absorption box 1 are not affected during a collision, please refer to Figure 3 ,in:

[0067] In the left-right direction of the frame structure, the distance between the vacuum pump assembly 6 and the energy absorption box 1, i.e., Y1, is greater than or equal to 45 mm. According to simulation analysis, this can ensure that the energy absorption box 1 is fully deformed during a collision and will not be affected.

[0068] In the left and right directions of the frame structure, the distance between the vacuum pump assembly 6 and the anti-collision beam 7, i.e., Y2, is greater than or equal to 0. Through simulation analysis, it can be ensured that when the anti-collision beam 7 is deformed by impact, it will not hit the vacuum pump assembly 6, and has a certain degree of protection.

[0069] In the front-to-rear direction of the frame structure, the distance between the mounting bracket 2 and the wheel 8 of the vehicle, i.e., Y3, is greater than or equal to 90 mm. After simulation analysis, it can be ensured that when the vehicle collision and deformation occurs, the vacuum pump assembly 6 is prevented from being hit by the wheel 8.

[0070] In summary of the above embodiments, the present application provides a frame structure and a vehicle, which, while taking into account the crushing energy absorption effect of the energy absorption box 1 area, meets the requirements of the brake vacuum pump assembly 6 for the installation structure strength and NVH properties. Specifically, by designing the sheet metal structure of the mounting bracket 2 and the mounting support plate 5, and using engineering simulation analysis methods, after multiple rounds of structural optimization, the safety performance of not affecting the crushing of the vehicle body in a collision is finally achieved, and at the same time, the brake vacuum pump can be properly protected in the event of a collision. The strength of the installation structure can ensure that the vehicle body is not affected by the force generated by the vibration of the vacuum pump assembly 6. During a collision, the vacuum pump assembly 6 and its related pipelines can be properly protected to avoid damage due to a collision or other external factors. In addition, while meeting the performance requirements of structural durability, NVH road noise, VD control (Vehicle Dynamics Control, vehicle dynamic control system), strength and dynamic stiffness, the lightweight requirements of the entire vehicle are comprehensively considered, and the structure is optimized to achieve the effect of reducing costs and weight.
