Description

Technical Field

[0001] The present application relates to the technical field of vehicle components, and in particular to a connection structure for an engine compartment bracket crossbeam and a vehicle. Background Art

[0002] In the engine compartment of a vehicle, a bracket crossbeam is usually provided. The bracket crossbeam is a reinforcing structural beam for connecting the left front longitudinal beam and the right front longitudinal beam of the vehicle. On the bracket crossbeam, various components with relatively large weights and vibration sources, such as a water pump, an engine water circuit three-way valve, and a cooler, are usually mounted. Therefore, when designing the bracket crossbeam, it is necessary to consider both the structural strengthening effect and the shock absorption and noise reduction effect of the bracket crossbeam at the same time.

[0003] When the existing bracket crossbeam is connected to the left front longitudinal beam and the right front longitudinal beam of the vehicle, it is usually connected by bolts in a hard connection manner. Since the mode and the dynamic stiffness of the installation points of the bracket crossbeam are relatively low, the vibration generated by the excitation source will be amplified along the entire structural path and transmitted to the vehicle interior through the vehicle body structure, resulting in obvious engine noise and vibration being felt in the passenger compartment, which affects the experience of passengers. Summary of the Utility Model

[0004] In view of this, the purpose of the present application is to provide a connection structure for an engine compartment bracket crossbeam and a vehicle, so as to solve the problem that the existing connection method of the bracket crossbeam will cause obvious engine noise and vibration to be felt in the passenger compartment.

Rather, the examples described herein are provided only to illustrate some of the many possible ways of implementing the methods, devices, and / or systems described herein that will be apparent after understanding the disclosure of the present application.

[0026] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "coupled to" another element, "above" another element, or "covering" another element, it can be directly "on", "connected to", "coupled to", "above", or "covering" the other element, or there can be one or more other elements intervening therebetween. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly coupled to" another element, "directly above" another element, or "directly covering" another element, there can be no other elements intervening therebetween.

[0027] As used herein, the term "and / or" includes any one of the listed related items and any combination of any two or more of them.

[0028] Although terms such as "first", "second", and "third" may be used herein to describe various components, elements, regions, layers, or sections, these components, elements, regions, layers, or sections are not limited by these terms. Rather, these terms are only used to distinguish one component, element, region, layer, or section from another. Thus, a first component, element, region, layer, or section described in the examples herein may also be referred to as a second component, element, region, layer, or section without departing from the teachings of the examples.

[0033] As Figures 1 to 5 shown, according to a first aspect of the present utility model, a connection structure for a cabin bracket crossbeam is provided. The connection structure for the cabin bracket crossbeam includes a crossbeam main body 1 and a flexible connection portion 2.

[0034] In the following description, reference will be made to Figures 1 to 5 specifically describe the specific structures of the above components of the connection structure for the cabin bracket crossbeam and the connection relationships of the above components.

[0035] As Figures 1 to 5 shown, in the embodiment, the crossbeam main body 1 can be connected to the longitudinal beam 3 of the vehicle through the flexible connection portion 2. The flexible connection portion 2 can include a bolt 21 and a bushing 22. The bolt 21 can be passed through the crossbeam main body 1 and the longitudinal beam 3 to perform a connecting function. The bushing 22 can be sleeved on the bolt 21, so that the bushing 22 can be clamped between the crossbeam main body 1 and the bolt 21, and the bushing 22 is clamped between the crossbeam main body 1 and the longitudinal beam 3. With such a setting, the crossbeam main body 1 does not make direct contact with the bolt 21 and the longitudinal beam 3, but is flexibly connected through the bushing 22, thereby effectively blocking the vibration transmission path and preventing vibration from being transmitted to the passenger cabin through the longitudinal beam 3.

[0036] Preferably, as Figures 1 to 4As shown, in the embodiment, the crossbeam main body 1 can be a frame formed by connecting profiles. The profiles can be aluminum profiles with a rectangular cross-section. Such that the crossbeam main body 1 is formed with an upper plate portion 11 and a lower plate portion 12 in the axial direction of the bolt 21. The flexible connection portion 2 can be installed on the lower plate portion 12 of the crossbeam main body 1 (i.e., the bolt 21 passes through the lower plate portion 12). And an avoidance hole 110 can be formed at the position of the upper plate portion 11 corresponding to the bolt 21 to facilitate the installation and disassembly of the bolt 21 by the operator.

[0037] In addition, preferably, as Figures 1 to 4 shown, in the embodiment, a plurality of rectangular frames can be formed inside the crossbeam main body 1, that is, a plurality of profiles are welded to each other and enclose to form a plurality of rectangular frames. The plurality of rectangular frames are arranged along the length direction of the crossbeam main body 1, and components with vibration sources such as three-way valves, heat exchangers, and electric water pumps can be installed on the plurality of rectangular frames.

[0038] Preferably, as Figure 1 shown, in the embodiment, the longitudinal beam 3 can include a left front longitudinal beam 301 and a right front longitudinal beam 302 which are oppositely arranged. The crossbeam main body 1 can be arranged between the left front longitudinal beam 301 and the right front longitudinal beam 302. Both ends in the length direction of the crossbeam main body 1 can be connected to the left front longitudinal beam 301 and the right front longitudinal beam 302 respectively through the flexible connection portion 2 to play a role in strengthening the vehicle structure.

[0039] More preferably, as Figures 3 to 5 shown, in the embodiment, the longitudinal beam 3 can include a longitudinal beam sheet metal 31 and a mounting bracket 32. Among them, the longitudinal beam sheet metal 31 can extend as a whole along a first direction (which can be the vertical direction as shown in Figure 5 ). The mounting bracket 32 can be welded and fixed to the plate surface of the longitudinal beam sheet metal 31. The bolt 21 of the flexible connection portion 2 can pass through the mounting bracket 32, and then the crossbeam main body 1 is fixed to the longitudinal beam 3.

[0040] Specifically, as Figure 5 shown, in the embodiment, the mounting bracket 32 can include a first plate portion 321 and a second plate portion 322. Among them, the extending direction of the first plate portion 321 can be the same as the extending direction of the longitudinal beam sheet metal 31 (i.e., extending along the first direction), so that the plate surface of the first plate portion 321 can be better welded to the plate surface of the longitudinal beam sheet metal 31. The second plate portion 322 can be connected to the end of the first plate portion 321. Preferably, the second plate portion 322 can extend along a second direction (which can be as shown in Figure 5extends in the horizontal direction shown in [the figure], such that the extending direction of the second plate portion 322 is perpendicular to the extending direction of the first plate portion 321. The first plate portion 321 and the second plate portion 322 may be integrally formed, and the bolt 21 may pass through the second plate portion 322, that is, the crossbeam main body 1 is connected to the second plate portion 322 through the flexible connection portion 2.

[0041] Preferably, as Figures 3 to 5 shown, in the embodiment, the flexible connection portion 2 may further include a gasket 23, a steel sleeve 24, and a nut 25. Among them, the shape of the gasket 23 may be annular. The gasket 23 may be sleeved on the bolt 21. Preferably, a radially protruding cap portion 210 may be formed at the top end of the bolt 21, and the gasket 23 may be disposed below the cap portion 210. The inner diameter of the gasket 23 may be smaller than the outer diameter of the cap portion 210 to prevent the gasket 23 from falling off the top end of the bolt 21. The steel sleeve 24 may be sleeved on the bolt 21. The steel sleeve 24 may be clamped between the gasket 23 and the mounting bracket 32, thereby fixing the position of the steel sleeve 24. The bushing 22 may be sleeved outside the steel sleeve 24. The nut 25 may be installed at the bottom end of the bolt 21. The nut 25 may be disposed below the second plate portion 322 of the mounting bracket 32 to perform a locking function.

[0042] Further, preferably, as Figure 5 shown, in the embodiment, the steel sleeve 24 may be a cylindrical structure. An extension portion may be formed on the outer periphery of the top end of the steel sleeve 24, and the extension portion extends radially along the steel sleeve 24. The gasket 23 may be located above the extension portion, and the bushing 22 is clamped between the extension portion and the second plate portion 322. When the nut 25 is tightened, the cap portion 210 at the top end of the bolt 21 will squeeze the gasket 23, the gasket 23 will squeeze the extension portion of the steel sleeve 24 downward, and the second plate portion 322 will move upward, thereby clamping the bushing 22 in the middle to achieve a fixing effect.

[0043] More preferably, as Figure 5As shown, in the embodiment, circular mounting holes 120 may be formed in the crossbeam main body 1. Specifically, the mounting holes 120 may be formed in the lower layer plate portion 12. Preferably, the shape of the bushing 22 may be approximately cylindrical. The bushing 22 may be a rubber bushing 22. Additionally, an annular groove may be formed in the center of the outer surface of the bushing 22. When the crossbeam main body 1 is connected to the mounting bracket 32 through the flexible connection portion 2, the mounting hole 120 may be clamped with the annular groove (i.e., the lower layer plate portion 12 provided with the mounting hole 120 is clamped in the annular groove). When arranged in this way, a rigid connection is adopted between the bolt 21 and the mounting bracket 32 to ensure the tightness of the connection. A flexible connection is adopted between the crossbeam main body 1, the bolt 21, and the mounting bracket 32 to block the vibration transmission path and prevent vibration and noise from being transmitted to the passenger compartment through the longitudinal beam 3.

[0044] Preferably, as Figures 1 to 4 shown, in the embodiment, two flexible connection portions 2 may be respectively arranged at both ends in the length direction of the crossbeam main body 1. Specifically, the flexible connection portions 2 may be arranged at the corners at both ends in the length direction of the crossbeam main body 1, so that the crossbeam main body 1 can be stably connected to the left front longitudinal beam 301 and the right front longitudinal beam 302.

[0045] In addition, as Figures 1 to 5 shown, according to the second aspect of the present invention, a vehicle is provided, and the vehicle includes the connection structure for the engine compartment bracket crossbeam as described above.

[0046] During use, both ends in the length direction of the crossbeam main body 1 are connected to the left front longitudinal beam 301 and the right front longitudinal beam 302 through the flexible connection portions 2. So that the crossbeam main body 1 does not make direct contact with the bolt 21 and the mounting bracket 32 of the longitudinal beam 3, but a flexible connection is made through the bushing 22. A rigid connection is provided between the bolt 21 and the mounting bracket 32. Thus, while ensuring the connection strength between the crossbeam main body 1 and the longitudinal beam 3, the vibration transmission path can be effectively blocked, thereby reducing the vibration and noise in the passenger compartment and greatly improving the comfort of passengers.

[0047] Finally, it should be noted that the above-described embodiments are only specific embodiments of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit it.
