Description

Technical Field

[0001] The present application relates to the technical field of vehicle brake system components, and in particular to a vehicle vacuum pump mounting structure and a vehicle. Background Art

[0002] With the progress of society and the development of science and technology, pure electric vehicles account for an increasingly higher proportion in the automobile market. Since pure electric vehicles are driven by electric motors and lack traditional fuel engines to provide a vacuum source for the hydraulic brake drive mechanism, pure electric vehicles need to use electric vacuum pumps to provide a vacuum source for the brake system. However, the vacuum pump has a very high speed when working, which will produce large amplitude vibration and noise, which has a great impact on the NVH and installation and maintainability of the vehicle. Therefore, the vacuum pump is usually installed on the front axle structure or longitudinal beam of the vehicle through a vibration reduction mounting bracket to reduce vibration transmission.

[0003] However, since the vacuum pump is installed at a lower position, the position of the vacuum pump outlet is lower than the position of the vehicle's wading line, which poses a risk of water ingress and blockage by mud and sand. Therefore, in order to increase the height of the vacuum pump outlet, the prior art usually adopts the method of raising the vacuum pump installation position or adding a bracket structure to the vacuum pump bracket to raise the installation height of the vacuum pump outlet. These two methods will reduce the layout space at the bottom of the vehicle and interfere with the routing of other components. On the other hand, they will increase the material and weight of the bracket structure, thereby affecting the vibration reduction effect and reducing the ride comfort of the vehicle.

[0038] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limiting the present application.

[0039] like Figures 1 to 3 As shown, this embodiment provides a vehicle vacuum pump installation structure, including a bracket body 2, a first positioning member 3 and a ventilation pipe 4, the bracket body 2 is connected to the bottom of the vehicle body 1, and is used to install the vacuum pump 5; the vehicle body 1 has a first positioning point 101, the first positioning point 101 is located above the bracket body 2, and the first positioning member 3 is arranged at the first positioning point 101; and the first end of the ventilation pipe 4 is used to communicate with the air outlet of the vacuum pump 5, and the second end of the ventilation pipe 4 is connected to the first positioning member 3. Since the setting position of the first positioning point 101 is higher than the setting position of the bracket body 2, after the ventilation pipe 4 is connected to the air outlet of the vacuum pump 5, the free end of the ventilation pipe 4 is fixed at the first positioning point 101 using the first positioning member 3, so as to achieve the purpose of raising the height of the air outlet of the vacuum pump 5 and avoid the problems of water ingress and clogging of the vacuum pump 5 by mud and sand; moreover, the bracket body 2 can also be set at a lower position without interfering with the routing of the bottom components of the vehicle; at the same time, the first positioning member 3 is set separately from the bracket body 2, and will not affect the vibration reduction effect of the bracket body 2. The overall structure is simple and reasonably arranged, which is easy to promote and apply.

[0040] It can be understood that the first positioning point 101 is located above the bracket body 2 , which means that when the bracket body 2 is installed at the bottom of the vehicle body 1 , the height of the first positioning point 101 above the ground is greater than the height of the bracket body 2 above the ground.

[0041] For example, in this embodiment, the first positioning point 101 is set below the cab floor 12 of the vehicle body 1. The specific structure is a convex welded stud welded below the cab floor 12 of the vehicle body 1. The first positioning member 3 can adopt a single tube clamp, and the single tube clamp is inserted into the convex welded stud to complete the setting of the first positioning member 3 at the first positioning point 101; the bracket body 2 is connected to the inner side of the chassis longitudinal beam 11 of the vehicle body 1 by welding or bolting. After the vacuum pump 5 is installed on the bracket body 2, the ventilation pipe 4 is connected to the vacuum pump 5 so that the first end of the ventilation pipe 4 is connected to the air outlet of the vacuum pump 5, and then the second end of the ventilation pipe 4 is clamped into the single tube clamp, that is, the first positioning member 3, to complete the connection between the ventilation pipe 4 and the first positioning member 3, so as to achieve the purpose of raising the air outlet height of the vacuum pump 5 to above the wading line of the whole vehicle. In this way, the vacuum pump 5 is prevented from getting water in and being blocked by mud and sand, thereby improving safety. The vibration reduction effect of the bracket body 2 and the routing of the bottom components of the vehicle are not affected, and the bottom space of the vehicle is reasonably utilized.

[0042] In some embodiments, Figure 2 and Figure 3 As shown, the vehicle vacuum pump installation structure also includes a second positioning member 6 and a third positioning member 7; wherein a second positioning point 102 is set on the bracket body 2, and the second positioning member 6 is arranged at the second positioning point 102; and the vent pipe 4 includes a front section 41, a middle section 42 and a rear section 43 sequentially distributed along its length direction, the front section 41 defines the first end of the vent pipe 4, the rear section 43 defines the second end of the vent pipe 4, and the middle section 42 is set with a third positioning point 103, so that the second positioning member 6 is connected to the vent pipe 4 at the front section 41, and the third positioning member 7 is connected to the vent pipe 4 and the wiring harness 51 of the vacuum pump 5 at the third positioning point 103. By setting the second positioning member 6 and the third positioning member 7, the connection stability of the vent pipe 4 can be effectively improved to prevent the vent pipe 4 from shaking excessively during the driving of the vehicle.

[0043] For example, in this embodiment, the second positioning point 102 may be a through hole provided on the bracket body 2, and the second positioning member 6 may be a cable tie with a positioning buckle, and the cable tie is inserted into the through hole, so that the second positioning member 6 is set at the second positioning point 102; then the cable tie is fixed to the front section 41 of the ventilating pipe 4, so that the connection between the ventilating pipe 4 and the second positioning member 6 is completed. The third positioning point 103 may be a point mark located at the middle section 42 of the ventilating pipe 4, and the third positioning member 7 may be a double pipe clamp, and the ventilating pipe 4 and the wiring harness 51 of the vacuum pump 5 are clamped at the third positioning point 103 by the third positioning member 7, so that the positioning connection setting of the third positioning member 7 at the third positioning point 103 is completed. In this way, the front section 41, the middle section 42 and the rear section 43 of the ventilation pipe 4 are respectively fixed by three positioning members, which significantly improves the connection stability of the ventilation pipe 4; at the same time, the third positioning member 7 can also position the wiring harness 51 of the vacuum pump 5, plan its line direction, and improve its connection stability.

[0044] Further, such as Figure 3 As shown, the third positioning member 7 includes a first tube clamp 71 for connecting the ventilation pipe 4 and a second tube clamp 72 for connecting the wiring harness 51. The first tube clamp 71 and the second tube clamp 72 are rotatably connected, so that the wiring harness 51 of the vacuum pump 5 and the ventilation pipe 4 are isolated from each other and do not contact each other, which can effectively prevent the ventilation pipe 4 and the wiring harness 51 from being worn and failing; at the same time, the first tube clamp 71 can be rotated relative to the second tube clamp 72, so that there is a variable active connection between the wiring harness 51 and the ventilation pipe 4, which reduces the installation direction restrictions on the wiring harness 51 and the ventilation pipe 4, facilitates installation and disassembly, and can effectively avoid the occurrence of serious safety faults such as the wiring harness 51 or the ventilation pipe 4 being stretched or broken due to the large vibration displacement generated when the vacuum pump 5 is working, thereby causing the vacuum pump 5 to fail.

[0045] In some embodiments, Figure 1 , Figure 4 and Figure 5 As shown, the bracket body 2 includes a first bracket 21, and the first bracket 21 includes a first side plate 211 and a second side plate 212 connected in an L shape. The first side plate 211 can be detachably fixedly connected to the longitudinal beam 11 of the vehicle body 1 by bolts, and the second side plate 212 is used to install the vacuum pump 5; wherein the second positioning point 102 is set on the second side plate 212. In this way, the first side plate 211 can be installed on the vertical side wall of the longitudinal beam 11, and the vacuum pump 5 can be supported by the second side plate 212, thereby improving the connection stability of the bracket.

[0046] It can be understood that, in this embodiment, the first side plate 211 and the second side plate 212 can be integrally formed into the first bracket 21 , which has high structural strength and stable performance.

[0047] In some embodiments, Figure 4 and Figure 5 As shown, a clearance hole 2121 is provided in the middle of the second side plate 212, and a pair of mounting holes 2122 are provided on the second side plate 212 on opposite sides of the clearance hole 2121; the vacuum pump 5 is placed in the clearance hole 2121 and connected to the mounting hole 2122 through a vibration-damping connector 52. The arrangement of the clearance hole 2121 and the mounting hole 2122 can, on the one hand, reduce the space occupied by the overall structure after the vacuum pump 5 is installed, and on the other hand, can make the vacuum pump 5 firmly and stably connected to the bracket.

[0048] It is understandable that the above-mentioned vibration-damping connector 52 can be a rubber vibration-damping pad with an embedded bushing, and the vibration-damping connection between the vacuum pump 5 and the second side plate 212 is realized by passing the bushing and the mounting hole 2122 through the bolt. At the same time, preferably, a projection welding nut 24 can also be provided below the mounting hole 2122, and the bolt is passed through and connected to the projection welding nut 24, which can improve the connection stability without increasing the thickness of the second side plate 212.

[0049] In some embodiments, Figure 4 As shown, the clearance hole 2121 extends inward from the free end of the second side plate 212 to the middle of the first side plate 211, so that the second side plate 212 is formed into two mounting arms 2123 disposed on both sides of the clearance hole 2121; wherein the mounting holes 2122 are symmetrically disposed on the two mounting arms 2123, and the second positioning point 102 is disposed on one of the mounting arms 2123. In this way, the vacuum pump 5 can be placed in the clearance hole 2121 from the free end side of the second side plate 212, thereby improving the convenience of disassembly and assembly of the vacuum pump 5.

[0050] In some embodiments, Figure 1 , Figure 6 and Figure 7 As shown, the bracket body 2 also includes a second bracket 22, and the first side plate 211 is detachably fixedly connected to the longitudinal beam 11 through the second bracket 22; the second bracket 22 includes a first mounting plate 221, a second mounting plate 222 and a connecting plate 223, the first mounting plate 221 and the second mounting plate 222 are vertically arranged and parallel to each other, and the connecting plate 223 is horizontally arranged and its two horizontal sides are respectively connected to the lower side of the first mounting plate 221 and the upper side of the second mounting plate 222; wherein the first mounting plate 221 is fixedly connected to the longitudinal beam 11, and the second mounting plate 222 is detachably fixedly connected to the first side plate 211. Through the arrangement of the second bracket 22, on the one hand, a spacing equivalent to the width of the connecting plate 223 can be reserved between the longitudinal beam 11 and the vacuum pump 5, so as to form a space for other component pipelines to pass through on the upper and lower sides of the connecting plate 223, thereby improving space utilization; on the other hand, the first bracket 21 and the vacuum pump 5, and the second bracket 22 and the vehicle body 1 can be assembled separately during the production process, thereby improving production efficiency.

[0051] Specifically, in this embodiment, the first mounting plate 221 can be fixedly connected to the longitudinal beam 11 by welding, which can improve the connection stability on the one hand, and reduce the setting of the connecting parts and avoid drilling holes on the longitudinal beam 11 on the other hand, thereby ensuring the structural strength of the longitudinal beam 11. The second mounting plate 222 can be detachably fixedly connected to the first side plate 211 by providing through holes for connection at corresponding positions of the second mounting plate 222 and the first side plate 211, and connecting the second mounting plate 222 and the first side plate 211 by passing bolts through the through holes of the second mounting plate 222 and the first side plate 211. At the same time, preferably, a projection welding nut can also be provided on the side of the second mounting plate 222 away from the first side plate 211, and the bolt is passed through and connected to the projection welding nut, which can improve the connection stability without increasing the thickness of the second mounting plate 222.

[0052] It can be understood that, in this embodiment, the first mounting plate 221, the second mounting plate 222 and the connecting plate 223 can be integrally formed into the second bracket 22, which has high structural strength and stable performance.

[0053] Further, such as Figure 7 As shown, the first preset angle α between the first mounting plate 221 and the connecting plate 223 is 90°-95°, preferably 95°, and the second preset angle β between the connecting plate 223 and the second mounting plate 222 is 90°-95°, preferably 95°. In this way, the strength and mode of the second bracket 22 can be guaranteed, and defects such as deformation and breakage of the second bracket 22 can be avoided.

[0054] In some embodiments, Figure 1 , Figures 4 to 7As shown, at least one reinforcing rib 23 is provided between the first side plate 211 and the second side plate 212, between the first mounting plate 221 and the connecting plate 223, and / or between the connecting plate 223 and the second mounting plate 222; wherein the reinforcing rib 23 includes a first reinforcing rib 231, a second reinforcing rib 232 and a third reinforcing rib 233, the first reinforcing rib 231 is provided on the relative inner sides of the first side plate 211 and the second side plate 212, and extends to the plate surfaces of the first side plate 211 and the second side plate 212; the second reinforcing rib 232 is provided on the relative inner sides of the first mounting plate 221 and the connecting plate 223, and extends to the plate surfaces of the first mounting plate 221 and the connecting plate 223; the third reinforcing rib 233 is provided on the relative inner sides of the second mounting plate 222 and the connecting plate 223, and extends to the plate surfaces of the second mounting plate 222 and the connecting plate 223. By providing the first reinforcing rib 231 , the second reinforcing rib 232 and the third reinforcing rib 233 , the structural strength of the bracket body 2 can be further improved.

[0055] For example, in this embodiment, two first reinforcing ribs 231 are provided, and the two first reinforcing ribs 231 are respectively located in the middle of the connection between the two mounting arms 2123 and the first side plate 211, and respectively extend from the inner plate surface of the first side plate 211 to the inner plate surface of the mounting arm 2123. The first mounting plate 221 defines a first plate surface 2211 for connecting with the vehicle body 1 and a second plate surface 2212 opposite to the first plate surface 2211, the connecting plate 223 defines a third plate surface 2231 and a fourth plate surface 2232 opposite to each other, two second reinforcing ribs 232 are provided, the two second reinforcing ribs 232 are arranged at intervals, and extend from the second plate surface 2212 of the first mounting plate 221 to the third plate surface 2231 of the connecting plate 223 respectively; the second mounting plate 222 defines a fifth plate surface 2221 for connecting with the first side plate 211 and a sixth plate surface 2222 opposite to the fifth plate surface 2221, and two third reinforcing ribs 233 are also provided, the two third reinforcing ribs 233 are arranged at intervals, and extend from the fourth plate surface 2232 of the connecting plate 223 to the sixth plate surface 2222 of the second mounting plate 222.
