The vacuum pump evacuates the vacuum tank to provide the vacuum degree required for the operation of the vacuum booster. The existing vacuum pump and vacuum tank are both arranged in the engine compartment space. However, the engine compartment space is limited, and there are many components to be arranged without interference, so the layout difficulty of the components is relatively high. In addition, during assembly, the vacuum tank needs to be separately installed on the longitudinal beam or the lower cross beam of the front windshield. The working space at the assembly position is narrow, and the operation difficulty is relatively high. Summary of the Utility Model

For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0031] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0032] Such as Figures 1-6As shown in the figure, the utility model provides a cabin longitudinal beam assembly, which can be a left cabin longitudinal beam assembly or a right cabin longitudinal beam assembly. A vacuum pump bracket 300 is fixedly connected to the cabin longitudinal beam assembly, and a vacuum pump assembly 200 is installed on the vacuum pump bracket 300. The cabin longitudinal beam assembly includes an outer longitudinal beam plate 1 and a longitudinal beam reinforcement 2, and the outer longitudinal beam plate 1 and the longitudinal beam reinforcement 2 are welded together, and a receiving space is formed after welding. The cabin longitudinal beam assembly further includes a partition member 3, which is arranged in the receiving space and fixedly connected to the outer longitudinal beam plate 1 and / or the longitudinal beam reinforcement 2 to partition the receiving space. Specifically, the partition member 3 includes a first partition plate 31 and a second partition plate 32, and the first partition plate 31 and the second partition plate 32 are arranged at intervals along the length direction of the cabin longitudinal beam assembly, and together with the outer longitudinal beam plate 1 and the longitudinal beam reinforcement 2, a vacuum chamber 10 is formed. The cabin longitudinal beam assembly further includes a vacuum connector, which is installed on the outer longitudinal beam plate 1 or the longitudinal beam reinforcement 2, and the vacuum connector is communicated with the vacuum chamber 10. Two vacuum connectors are provided, one of which is used to connect with the vacuum pump assembly 200, and the other is used to connect with the vacuum booster assembly 100. Specifically, the shapes of the first partition plate 31 and the second partition plate 32 match the shapes of the receiving spaces at their respective installation positions, and their outer edges are welded to the inner side walls of the receiving spaces, and the welds between them are continuously arranged, so that a sealed vacuum chamber 10 is formed between the first partition plate 31, the second partition plate 32, the outer longitudinal beam plate 1 and the longitudinal beam reinforcement 2, and the vacuum pump assembly 200 and the vacuum booster assembly 100 are respectively connected to the vacuum chamber 10 through two vacuum connectors, so as to achieve the same technical effect as the vacuum tank in the prior art, replace the vacuum tank in the prior art, thereby reducing the occupation of the cabin space, reducing the layout difficulty of the components in the cabin, and not involving the assembly operation of the vacuum tank, reducing the assembly process and difficulty.

[0033] Further, the two vacuum connectors are a first connector 41 and a second connector 42. The first connector 41 is used to connect with the vacuum pump assembly 200, and the second connector 42 is used to connect with the vacuum booster assembly 100. A first vacuum tube 410 is connected between the first connector 41 and the vacuum pump assembly 200 to communicate the vacuum pump assembly 200 with the vacuum chamber 10; a second vacuum tube 420 is connected between the second connector 42 and the vacuum booster assembly 100 to communicate the vacuum booster assembly 100 with the vacuum chamber 10. The connection position of the first connector 41 with the vacuum chamber 10 is below the connection position of the second connector 42 with the vacuum chamber 10 to improve the vacuum pumping efficiency of the vacuum pump assembly 200 and reduce the pipeline length.

[0034] Even further, please refer to Figures 2-6As shown, the separator 3 further includes a third partition plate 33. The third partition plate 33 extends along the length direction of the cabin longitudinal beam assembly, and both ends of the third partition plate 33 are respectively welded to the first partition plate 31 and the second partition plate 32. The weld seams between the third partition plate 33 and the first partition plate 31 and the second partition plate 32 are continuously arranged to ensure good airtightness at the welded joints. The first partition plate 31, the second partition plate 32, and the third partition plate 33 form a U-shaped structure, and together with the longitudinal beam outer plate 1 or the longitudinal beam reinforcement 2, they form a vacuum chamber 10. In the prior art, several process holes are usually provided on the longitudinal beam outer plate 1 or the longitudinal beam reinforcement 2 to avoid the occurrence of electrophoretic cavities during the painting and electrophoretic process. Therefore, to ensure the airtightness of the vacuum chamber 10, additional sealing measures need to be taken at the process holes during the assembly process. Therefore, by providing the third partition plate 33, in the case where the longitudinal beam outer plate 1 or the longitudinal beam reinforcement 2 has process holes at the position of the vacuum chamber 10, it is possible to ensure the airtightness of the vacuum chamber 10 without additional operations on the process holes, and the reliability is higher. Figures 2-6 Correspondingly, it is the case where the longitudinal beam outer plate 1 has process holes at the corresponding positions. Correspondingly, the third partition plate 33 is welded to one end of the first partition plate 31 or the second partition plate 32 close to the longitudinal beam outer plate 1 and is spaced from the longitudinal beam outer plate 1 for easy assembly. For the structure of this embodiment, one of the vacuum connectors is installed on the longitudinal beam outer plate 1. Since the longitudinal beam outer plate 1 is spaced from the third partition plate 33, the vacuum connector passes through the longitudinal beam outer plate 1 and then connects to the third partition plate 33, thereby realizing communication with the vacuum chamber 10. The specific connection method between the vacuum connector and the third partition plate 33 is not limited here as it is prior art, and welding connection is preferably used. Specifically, during the production process, the first partition plate 31 and the second partition plate 32 can be first welded to the longitudinal beam reinforcement 2, and the third partition plate 33 can be welded to the first partition plate 31, the second partition plate 32, and the longitudinal beam reinforcement 2, and then the longitudinal beam reinforcement 2 and the longitudinal beam outer plate 1 can be welded. Due to the setting of the third partition plate 33, the weld seam between the first partition plate 31 and the second partition plate 32 and the longitudinal beam outer plate 1 can be cancelled, which can further simplify the process. The longitudinal beam reinforcement 2 in this embodiment is also a U-shaped structure. The U-shaped structure of the separator 3 and the U-shaped structure of the longitudinal beam reinforcement 2 can form a sealed approximate cuboid or cube-shaped sealed space through combination, which is the vacuum chamber 10 in this embodiment. Similarly, for the case where the longitudinal beam reinforcement 2 has process holes at the corresponding positions, only the position of the third partition plate 33 needs to be adjusted, and the principle of forming the vacuum chamber 10 is the same or similar to the case where the longitudinal beam outer plate 1 has process holes at the corresponding positions, so it will not be elaborated here.

[0035] Specifically, please refer to Figures 2-5As shown in the figure, the longitudinal beam reinforcement 2 includes a top plate 21, a bottom plate 23, and side plates 22 for connecting the top plate 21 and the bottom plate 23. The top plate 21 and the bottom plate 23 are arranged in parallel, and the side plates 22 are perpendicular to the top plate 21 and the bottom plate 23. The top plate 21, the side plates 22, and the bottom plate 23 are of an integrally formed structure, such as integrally stamping or integrally die-casting. The top plate 21 and the bottom plate 23 are respectively used for welding connection with the longitudinal beam outer plate 1. The top plate 21 and the bottom plate 23 are both provided with flanges for welding with the longitudinal beam outer plate 1, and can be electrically welded or arc welded with the longitudinal beam outer plate 1 through the flanges. The top end and the bottom end of the U-shaped separator 3 are respectively welded to the top plate 21 and the bottom plate 23, that is, the top ends of the first partition 31, the second partition 32, and the third partition 33 are all welded to the top plate 21, and the bottom ends are all welded to the bottom plate 23. The first partition 31 and the second partition 32 are perpendicular to the side plates 22 and are welded to the side plates 22. The third partition 33 is approximately parallel to the side plates 22. A vacuum chamber 10 is formed by welding the separator 3 to the longitudinal beam reinforcement 2, and an accommodation space is formed after the longitudinal beam reinforcement 2 is welded to the longitudinal beam outer plate 1, so that the vacuum chamber 10 is located in the accommodation space, reducing the number of parts, saving the layout space of the engine room, saving the cost of parts, and improving the assembly efficiency.

[0036] Optionally, in other embodiments, the third partition 33 can also be provided with two (not shown in the figure), and the two third partitions 33 are arranged at intervals along the width direction of the engine room longitudinal beam assembly. One of the third partitions 33 is welded to one end of the first partition 31 and the second partition 32 close to the longitudinal beam outer plate 1, and the other third partition 33 is welded to one end of the first partition 31 and the second partition 32 close to the side plates 22 of the longitudinal beam reinforcement 2, and the welds are continuously arranged to ensure the airtightness at the welded joints. Thus, the first partition 31, the second partition 32, and the two third partitions 33 form a frame structure, and together with the top plate 21 and the bottom plate 23 of the longitudinal beam reinforcement 2, form a vacuum chamber 10. Setting the third partition 33 to two further reduces the structural limitations on the longitudinal beam reinforcement 2. By changing the structure of the separator 3, a sealed vacuum chamber 10 can also be formed when there are process holes on the side plates 22 of the longitudinal beam reinforcement 2 and the longitudinal beam outer plate 1.

[0037] Optionally, in another embodiment, the separator 3 further includes a fourth partition plate (not shown in the figure), and the fourth partition plate is welded to the top end or the bottom end of the frame structure. When the fourth partition plate is arranged at the top end of the frame structure, the fourth partition plate is simultaneously welded to the top ends of the first partition 31, the second partition 31, and the third partition 33, and the welds are continuously arranged. At this time, the separator 3 and the bottom plate 23 of the longitudinal beam reinforcement 2 together form a vacuum chamber 10, which can meet the scenario where there are process holes on the top plate 21 of the longitudinal beam reinforcement 2. Similarly, when the fourth partition plate is arranged at the bottom end of the frame structure, it can meet the scenario where there are process holes on the bottom plate 23 of the longitudinal beam reinforcement 2.

[0038] Optionally, in another embodiment, the fourth partition plate may be provided in two (not shown in the figure). The two fourth partition plates are respectively welded to the top and bottom of the frame structure, and the weld seams are continuously arranged to form the vacuum chamber 10. That is, the separator 3 itself forms the vacuum chamber 10, and its connection method with the longitudinal beam reinforcement 2 or the longitudinal outer plate 1 of the longitudinal beam can be fastener connection or welding connection. Considering the convenience of processing, the connection method is still preferably welding connection.

[0039] The utility model provides a front-end module, which includes a vacuum booster assembly 100 and a vacuum pump assembly 200, and also includes the engine compartment longitudinal beam assembly in this embodiment. The vacuum pump assembly 200 is installed on the engine compartment longitudinal beam assembly through a vacuum pump bracket 300. The vacuum pump assembly 200 is connected to one of the vacuum connectors and is used to evacuate the vacuum chamber 10. The vacuum booster assembly 100 is connected to the other vacuum connector. The vacuum chamber 10 provides vacuum degree for the vacuum booster assembly 100 to make the brake master cylinder on the vacuum booster assembly 100 act. By providing the engine compartment longitudinal beam assembly in this embodiment, without changing the shape of the engine compartment longitudinal beam assembly, the vacuum tank in the prior art is replaced, thereby saving the layout space of the engine compartment, simplifying the assembly process, and reducing the cost of vehicle parts.

[0040] The utility model also provides a vehicle, which includes the front-end module in this embodiment. By providing the front-end module of the utility model, there is no need to provide a vacuum tank to reduce the difficulty of parts layout and production cost.

[0041] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limiting the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
