Description

Technical Field

[0001] The present application relates to the technical field of vehicles, and in particular, to a water tank mounting frame, a body-in-white and an automobile. Background Art

[0002] As cars increasingly enter thousands of households, the safety of vehicles has also been increasingly valued by consumers. At the same time, automotive safety test and evaluation institutions have also raised the requirements for automotive safety design. For example, C-NCAP (China New Car Assessment Program) has proposed to increase the speed of the frontal collision of cars from 50 kph to 56 kph, and the collision energy has increased by 25%. This requires more collision energy absorption space. In the frontal collision of a car at 56 kph, one of the assessment indicators is the OLC (Occupant Load Coefficient) value. A vehicle with a relatively low OLC value provides better protection for the occupants.

[0003] Under normal circumstances, the purpose of reducing the OLC (Occupant Load Coefficient) can be achieved by increasing the energy absorption space in the front cabin. However, this design will increase the volume of the front of the vehicle. Since the vehicle model design is greatly affected by the styling, the vehicle models favored by consumers are not necessarily those with a very long front of the car. Therefore, higher requirements are put forward for the design of the car. Summary of the Utility Model

[0004] Based on this, a water tank mounting frame, a body-in-white and an automobile are provided. The water tank mounting frame can reduce the OLC value, does not increase the volume of the front of the vehicle, does not affect the styling of the vehicle model, and improves the satisfaction of consumers.

[0005] To this end, in a first aspect, an embodiment of the present application provides a water tank mounting frame, including an upper cross beam; an upper side beam spaced from the upper cross beam; and an adjusting beam, one end of which is connected to the upper cross beam and the other end of which is connected to the upper side beam. A closed chamber is provided inside the adjusting beam.

[0006] In one embodiment, the adjusting beam includes an upper plate and a lower plate connected to each other, and the closed chamber is formed by enclosing the upper plate and the lower plate.

[0007] In one embodiment, the upper plate is provided with a first reinforcing rib extending along the extending direction of the upper plate, and / or the lower plate is provided with a second reinforcing rib extending along the extending direction of the lower plate.

[0008] In one embodiment, the upper plate is provided with a first positioning portion, and the lower plate is provided with a second positioning portion adapted to the first positioning portion.

[0009] In one embodiment, at least two first positioning portions are provided, and at least two of the first positioning portions are respectively located at two ends of the closed chamber. At least two second positioning portions are provided, and at least two of the second positioning portions are respectively located at two ends of the closed chamber.

[0010] In one embodiment, the adjusting beam is inclined. The upper end of the inclined adjusting beam is connected to the upper side beam, and the lower end of the inclined adjusting beam is connected to the upper cross beam. The height of the closed chamber gradually increases in the direction towards the upper side beam.

[0011] In one embodiment, a spacer block is provided between the upper cross beam and the adjusting beam to make the adjusting beam horizontally arranged, and the height of the closed chamber is at the same horizontal plane.

[0012] In one embodiment, a water tank column is further provided on the upper cross beam, and a front longitudinal beam is further provided on the upper side beam. An energy absorption box is connected between the water tank column and the longitudinal beam.

[0013] In a second aspect, an embodiment of the present application provides a white vehicle body including the water tank mounting frame as described in any one of the above.

[0014] In a third aspect, an embodiment of the present application provides a vehicle including the white vehicle body as described above.

[0015] According to the water tank mounting frame, white vehicle body and vehicle provided by the embodiments of the present application, the water tank mounting frame includes an upper cross beam, an upper side beam and an adjusting beam; the upper side beam and the upper cross beam are arranged at intervals; one end of the adjusting beam is connected to the upper cross beam, and the other end is connected to the upper side beam. A closed chamber is arranged inside the adjusting beam. The closed chamber arranged inside the adjusting beam increases the strength of the adjusting beam. During a collision, the closed chamber can facilitate the adjusting beam to absorb the energy generated by the collision, which is equivalent to increasing the front overhang length, thereby reducing the OLC value to meet the current C-NCAP requirements. Compared with increasing the energy absorption by increasing the front cabin energy absorption space and increasing the shotgun to increase the energy absorption, the present application can adjust the shape of the adjusting beam according to the shape of the vehicle head by arranging the adjusting beam, without changing the front subframe, front longitudinal beam, shotgun structure, and without additionally increasing the front cabin energy absorption space. Only by adjusting the shotgun and the adjusting beam of the water tank frame can the purpose of reducing the OLC be achieved, which does not affect the vehicle model styling and can improve the satisfaction of consumers.

Detailed implementation manners

[0024] In order to make the objectives, technical solutions and advantages of the present application more clear and understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0025] It should be noted that the diagrams provided in this embodiment only illustrate the basic concept of the present invention in a schematic manner. Therefore, only the components related to the present invention are shown in the diagrams, rather than being drawn according to the number, shape and size of the components in actual implementation. The type, quantity and proportion of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0026] The structures, proportions, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those skilled in this technology to understand and read, and are not used to limit the limiting conditions under which the present invention can be implemented. Therefore, they do not have technical essential significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects that the present invention can produce and the objectives that can be achieved, should still fall within the scope that can be covered by the technical content disclosed by the present invention.

[0027] The orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "middle", "longitudinal", "lateral", "horizontal", "inner", "outer", "radial", "circumferential", etc. cited in this specification is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of simplified description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation on the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0028] If the purpose of reducing the OLC (Occupant Load Coefficient) is achieved by increasing the front cabin energy absorption space, this design will increase the volume of the front of the vehicle. Due to the great influence of the vehicle model design on the styling, the front of the car is relatively long, which does not meet the preferences of consumers.

[0029] Refer to Figures 1-3 , Figure 1 shows a structural schematic diagram of a water tank mounting frame provided by an embodiment of the present application Figure 1 , Figure 2 shows a structural schematic diagram of a water tank mounting frame provided by an embodiment of the present application Figure 2 , Figure 3 shows a partial structural schematic diagram of a water tank mounting frame provided by an embodiment of the present application.

[0030] To solve the above technical problems, the present application includes a water tank mounting frame, which includes an upper cross beam 1, an upper side beam 2, and an adjustment beam 3. The upper side beam 2 is arranged at an interval from the upper cross beam 1; one end of the adjustment beam 3 is connected to the upper cross beam 1, and the other end is connected to the upper side beam 2. A closed chamber (not shown in the figure) is arranged inside the adjustment beam 3.

[0031] It should be understood that the upper side beam 2 is a shotgun upper side beam, that is, the upper side beam of the front wheel housing. The upper side beam 2 is located at one end of the upper cross beam 1 along its own length direction. One end of the upper side beam 2 along its own length direction faces the upper cross beam 1 and is arranged at an interval from the upper cross beam 1. An adjustment beam 3 is arranged between the upper cross beam 1 and the upper side beam 2. One end of the adjustment beam 3 along its own extension direction is connected to the upper cross beam 1, and the connection method can be bolt fixation, welding or other connection methods, which are not limited in the present application. The other end of the adjustment beam 3 is connected to the upper side beam 2, and the connection method can be bolt fixation, welding or other connection methods, which are not limited in the present application.

[0032] The interior of the adjusting beam 3 is provided with a closed chamber, which extends along the extending direction of the adjusting beam 3. The setting of the closed chamber increases the strength of the adjusting beam 3. During a collision, the setting of the closed chamber facilitates the adjusting beam 3 to absorb the energy generated by the collision, which is equivalent to increasing the front overhang length, thereby reducing the OLC value to meet the current C-NCAP requirements. Compared with increasing the energy absorption by increasing the front cabin energy absorption space and increasing the shotgun to increase the energy absorption, in this application, through the setting of the adjusting beam 3, the shape of the adjusting beam 3 can be adjusted according to the shape of the vehicle head, without changing the front subframe, front longitudinal beam, and shotgun structure, and without additionally increasing the front cabin energy absorption space. Only by adjusting the adjusting beam between the shotgun and the radiator grille can the purpose of reducing the OLC be achieved. The optimization method is simple, and the mold cost brought by the design change is low, even for a completely new mold opening. Moreover, this application does not increase the volume of the vehicle head, does not affect the vehicle model's styling, and can improve the satisfaction of consumers.

[0033] The adjusting beam 3 in this application can be set by integral forming or formed by enclosing multiple plates, and this application does not make any restrictions.

[0034] Referring to Figures 4-6 , Figure 4 shows a bottom view of an adjusting beam provided by an embodiment of this application, Figure 5 shows a top view of an adjusting beam provided by an embodiment of this application, Figure 6 shows a structural schematic diagram of an adjusting beam provided by an embodiment of this application.

[0035] In some optional embodiments, the adjusting beam 3 includes an upper plate 31 and a lower plate 32 that are connected to each other. The upper plate 31 and the lower plate 32 enclose a closed chamber. At least one of the upper plate 31 and the lower plate 32 is recessed to form a groove, so that a closed chamber can be formed after the upper plate 31 and the lower plate 32 are fitted together. In one example, the upper plate 31 is recessed upward to form a groove, and the lower plate 32 is not recessed; in one example, the lower plate 32 is recessed downward to form a groove, and the upper plate 31 is not recessed; in one example, the upper plate 31 is recessed upward to form a groove, and the lower plate 32 is also recessed downward to form a groove.

[0036] The upper plate 31 and the lower plate 32 are connected by welding. To improve the connection stability between the upper plate 31 and the lower plate 32, a welding edge extends from the periphery of the upper plate 31, and a welding edge also extends from the periphery of the lower plate 32. During welding, the welding edge of the upper plate 31 is fitted with the welding edge of the lower plate 32, thereby improving the convenience and firmness of the welding between the upper plate 31 and the lower plate 32.

[0037] To further improve the stability of the connection between the upper plate 31 and the lower plate 32, the welding edge of the upper plate 31 can wrap the welding edge of the lower plate 32, or the welding edge of the lower plate 32 can wrap the welding edge of the upper plate 31, so as to improve the sealing performance of the closed chamber, and further improve the strength of the adjusting beam 3.

[0038] Moreover, through the arrangement of the upper plate 31 and the lower plate 32 in this application, it can be prepared by a mold, reducing the cost of preparing the adjusting beam 3.

[0039] Mounting holes for connecting with the upper cross beam 1 or the upper side beam 2 are also provided on the end side of the adjusting beam 3. Correspondingly, corresponding mounting holes are provided at the upper plate 31 and the lower plate 32. Multiple mounting holes can be provided to improve the connection stability between the adjusting beam 3 and the upper cross beam 1 or the upper side beam 2.

[0040] In some alternative embodiments, the upper plate 31 is provided with a first reinforcing rib 311, and the first reinforcing rib 311 extends along the extending direction of the upper plate 31.

[0041] The upper plate 31 and the first reinforcing rib 311 are made of the same material and are integrally formed. The first reinforcing rib 311 can also be formed by stamping the upper plate 31. The arrangement of the first reinforcing rib 311 can improve the strength of the upper plate 31. The first reinforcing rib 311 extends along the length direction of the upper plate 31. In one example, the first reinforcing rib 311 is located at the recess of the upper plate 31 to improve the strength of the recess of the upper plate 31. The first reinforcing rib 311 is provided with multiple ones and is arranged at intervals along the width direction of the upper plate 31.

[0042] The lower plate 32 is provided with a second reinforcing rib (not shown in the figure), and the second reinforcing rib extends along the extending direction of the lower plate 32. The lower plate 32 and the second reinforcing rib are made of the same material and are integrally formed. The second reinforcing rib can also be formed by stamping the lower plate 32. The arrangement of the second reinforcing rib can improve the strength of the lower plate 32. The second reinforcing rib extends along the length direction of the lower plate 32. In one example, the second reinforcing rib is located at the recess of the lower plate 32 to improve the strength of the recess of the lower plate 32. The second reinforcing rib is provided with multiple ones and is arranged at intervals along the width direction of the lower plate 32.

[0043] Among them, the upper plate 31 can be provided with the first reinforcing rib 311, and the lower plate 32 can also be provided with the second reinforcing rib at the same time. It is also possible that the upper plate 31 is provided with the first reinforcing rib 311 while the lower plate 32 is not provided with the second reinforcing rib, or the upper plate 31 is not provided with the first reinforcing rib 311 while the lower plate 32 is provided with the second reinforcing rib.

[0044] In some alternative embodiments, the upper plate 31 is provided with a first positioning portion 312, and the lower plate 32 is provided with a second positioning portion 322 adapted to the first positioning portion 312. The position of the first positioning portion 312 is set corresponding to the position of the second positioning portion 322. Any one of the first positioning portion 312 and the second positioning portion 322 is a protrusion, and the other is a groove adapted to the protrusion. The present application does not limit the shapes of the protrusion and the groove. The protrusion can be cylindrical, and the groove is a circular groove adapted to the protrusion so that the protrusion can extend into the groove. The protrusion can also be cuboid-shaped, and the groove is a rectangular groove adapted to the protrusion. After the protrusion extends into the groove, the protrusion cannot rotate in the groove, further improving the positioning accuracy of the first positioning portion 312 and the second positioning portion 322. In one example, the first positioning portion 312 is a protrusion and the second positioning portion 322 is a groove. In one example, the first positioning portion 312 is a groove and the second positioning portion 322 is a protrusion. When assembling the adjusting beam 3, the first positioning portion 312 and the second positioning portion 322 are engaged and positioned, so as to position the upper plate 31 and the lower plate 32, and then the upper plate 31 and the lower plate 32 are welded. The settings of the first positioning portion 312 and the second positioning portion 322 can prevent the upper plate 31 and the lower plate 32 from moving relative to each other during welding, thereby improving the welding accuracy and stability of the upper plate 31 and the lower plate 32.

[0045] In some alternative embodiments, there are at least two first positioning portions 312, and the at least two first positioning portions 312 are respectively located at both ends of the first reinforcing rib 311. There are at least two second positioning portions 322, and the at least two second positioning portions 322 are respectively located at both ends of the second reinforcing rib. The provision of at least two first positioning portions 312 and second positioning portions 322 can improve the positioning accuracy of the upper plate 31 and the lower plate 32. Taking the example where there are two first positioning portions 312 and two second positioning portions 322, the two first positioning portions 312 are respectively located at both ends of the first reinforcing rib 311, so as not to affect the strength of the recessed portion of the upper plate 31, and the two second positioning portions 322 are respectively located at both ends of the second reinforcing rib, thereby not affecting the strength of the recessed portion of the lower plate 32.

[0046] Refer to Figure 1 、 Figure 2 and Figure 6, in some alternative embodiments, the adjusting beam 3 is inclined. The upper end of the inclined adjusting beam 3 is connected to the upper side beam 2, and the lower end of the inclined adjusting beam 3 is connected to the upper cross beam 1. The height of the closed chamber gradually increases in the direction towards the upper side beam 2. Due to the volume setting of the vehicle head, the adjusting beam 3 is inclined, so that the volume of the vehicle head can remain unchanged. Since the volume of the vehicle head is smaller at the position towards the upper cross beam 1, the height of the closed chamber is smaller at the position towards the upper cross beam 1. Since the volume of the vehicle head is larger at the position towards the upper side beam 2, the height of the closed chamber is larger at the position towards the upper side beam 2. The larger the closed chamber, the stronger the strength of the adjusting beam 3. Therefore, according to the limitation of the vehicle head in this application, the height of the closed chamber gradually increases in the direction towards the upper side beam 2.

[0047] In some alternative embodiments, a spacer block (not shown in the figure) is provided between the upper cross beam 1 and the adjusting beam 3 to make the adjusting beam 3 horizontally arranged, and the height of the closed chamber is at the same horizontal plane. Since the height of the upper plane of the upper cross beam 1 is less than the height of the upper plane of the upper side beam 2, a spacer block is provided between the upper cross beam 1 and the adjusting beam 3 so that the height of the upper plane of the spacer block is equal to the height of the upper plane of the upper side beam 2. At this time, the adjusting beam 3 can be arranged in a cuboid shape, and the closed chamber is conformally arranged with the adjusting beam 3, that is, the height of the closed chamber is at the same horizontal plane, which can further improve the strength of the adjusting beam 3, further reduce the OLC value, and meet the C-NCAP requirements.

[0048] In some alternative embodiments, the upper cross beam 1 is further provided with a water tank column 11, and the upper side beam 2 is further provided with a front longitudinal beam 21. An energy absorption box 4 is connected between the water tank column 11 and the front longitudinal beam 21. The connection between the water tank column 11 and the upper cross beam 1 can be a fixed connection or a detachable connection, which is not limited in this application. In one example, the water tank column 11 and the upper cross beam 1 are connected by bolts. The water tank column 11 is vertically arranged with respect to the upper cross beam 1, and the water tank column 11 is located below the upper cross beam 1. The connection between the upper side beam 2 and the front longitudinal beam 21 can be a fixed connection or a detachable connection, which is not limited in this application. In one example, the upper side beam 2 and the front longitudinal beam 21 are connected by bolts. The front longitudinal beam 21 is located below the upper side beam 2, and there is a gap between the front longitudinal beam 21 and the water tank column 11. The energy absorption box 4 is located between the front longitudinal beam 21 and the water tank column 11. One end of the energy absorption box 4 is connected to the front longitudinal beam 21, and the other end is connected to the water tank column 11. The energy absorption box 4 can absorb part of the energy generated during a collision, reduce the OLC value, and meet the C-NCAP requirements.

[0049] Furthermore, the upper side beam 2 is further connected to a front column 22, and the other end of the front column 22 is connected to the front longitudinal beam 21 to improve the connection stability between the upper side beam 2 and the front longitudinal beam 21.

[0050] This application also includes a body-in-white, which includes the radiator mounting frame described in any one of the above. The radiator mounting frame includes an upper cross member 1, an upper side member 2, and an adjustment beam 3. The upper side member 2 is arranged at an interval from the upper cross member 1. One end of the adjustment beam 3 is connected to the upper cross member 1, and the other end is connected to the upper side member 2. A closed chamber is arranged inside the adjustment beam 3.

[0051] A closed chamber is arranged inside the adjustment beam 3. The closed chamber extends along the extension direction of the adjustment beam 3. The arrangement of the closed chamber increases the strength of the adjustment beam 3. During a collision, the arrangement of the closed chamber facilitates the adjustment beam 3 to absorb the energy generated by the collision, which is equivalent to increasing the front overhang length, thereby reducing the OLC value to meet the current C-NCAP requirements. Compared with increasing the energy absorption by increasing the front cabin energy absorption space and increasing the shotgun to increase the energy absorption, through the arrangement of the adjustment beam 3 in this application, the shape of the adjustment beam 3 can be adjusted according to the shape of the vehicle head, without changing the front subframe, front longitudinal beam, and shotgun structure, and without additionally increasing the front cabin energy absorption space. Only by adjusting the shotgun and the adjustment beam of the radiator frame can the purpose of reducing the OLC be achieved, and thus the vehicle styling is not affected, which can improve the satisfaction of consumers.

[0052] This application also includes an automobile, which includes the body-in-white described above.

[0053] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0054] The above-described embodiments only represent several implementation manners of this application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of this application, several deformations and improvements can still be made, and these all belong to the protection scope of this application. Therefore, the protection scope of this application patent shall be subject to the appended claims.
