[0019] FIG. 1 is a partial structural schematic view of the mounting and positioning structure of the front face component of the vehicle body according to an embodiment of the application; DETAILED DESCRIPTION
[0020] Please refer to Figure 1 and Figure 2In an embodiment, the mounting positioning structure of the front face component of the vehicle body includes a hood (not shown in the figure), a fender (not shown in the figure), a longitudinal beam 100, and a positioning adjusting piece 200, the longitudinal beam 100 is provided with a mounting surface 111 composed of a P-axis direction and a Q-axis direction, and the mounting surface 111 is provided with a pre-hanging hole group 120.
[0021] The pre-hanging hole group 120 refers to a group of mounting and adjusting holes distributed on the mounting surface 111, which can be implemented by a long round hole or a special-shaped hole, and the movement limit is formed by the contact surface of the hole wall and the positioning adjusting piece 200.
[0022] Before the start of fixed assembly, the positioning adjusting piece 200 can be hung on the longitudinal beam 100 through the pre-hanging hole group 120, at this time, the positioning adjusting piece 200 and the longitudinal beam 100 are not fixedly connected, that is, the positioning adjusting piece 200 can be taken off from the longitudinal beam 100 at any time, and the positioning adjusting piece 200 can move within a limited range relative to the longitudinal beam 100, specifically, the positioning adjusting piece 200 can be movably limited in cooperation with the pre-hanging hole group 120 along the P-axis direction and the Q-axis direction respectively, and the longitudinal beam 100 is provided with a first positioning hole 130, and the positioning adjusting piece 200 is provided with a second positioning hole 210, the area of the first positioning hole 130 is greater than the area of the second positioning hole 210.
[0023] The overlapping relationship of the orthographic projection of the first positioning hole 130 and the second positioning hole 210 refers to the complete overlap of the two in the vertical projection direction, which can be achieved by designing a circular hole and the diameter of the first positioning hole 130 is slightly larger than that of the second positioning hole 210. This design ensures that the two holes are always in complete communication state during welding, which provides guarantee for the final precise positioning.
[0024] The circular hole refers to a hole structure with a complete circumference, which can be implemented by stamping or drilling process, and the edge is not angular, which is convenient for processing positioning. The diameter of the first positioning hole 130 is greater than the diameter of the second positioning hole 210, which can be designed as the diameter of the second positioning hole 210 is 0.5-2mm smaller than that of the first positioning hole 130, so that the second positioning hole 210 can completely fall into the projection range of the first positioning hole 130 during welding, which ensures the positioning accuracy.
[0025] But not limited to this, in other embodiments, the first positioning hole 130 and the second positioning hole 210 can also be square holes, and the side length of the first positioning hole 130 is greater than that of the second positioning hole 210.
[0026] When the positioning adjusting piece 200 moves to any position of the pre-hanging hole group 120, the orthographic projection of the first positioning hole 130 along the R-axis direction completely covers the orthographic projection of the second positioning hole 210 along the R-axis direction, wherein the P-axis direction, the Q-axis direction and the R-axis direction are perpendicular to each other.
[0027] It should be noted that the new energy vehicle establishes a three-dimensional coordinate system during assembly, wherein the X-axis direction coordinate system is established in the front-rear direction of the new energy vehicle, the Y-axis direction coordinate system is established in the left-right direction of the new energy vehicle, and the Z-axis direction coordinate system is established in the up-down direction of the new energy vehicle. Moreover, the P-axis direction, the Q-axis direction and the R-axis direction do not necessarily correspond to the X-axis direction, the Y-axis direction and the Z-axis direction completely, for example, the X-axis direction and the P-axis direction can have a certain angle relationship, similarly, the Y-axis direction and the Q-axis direction can have a certain angle relationship, and the Z-axis direction and the R-axis direction can also have a certain angle relationship.
[0028] After that, formal fixing assembly is started, at this time, the longitudinal beam 100 and the positioning adjusting piece 200 are clamped by the clamp at a certain station of the main line of the factory welding workshop, it should be noted that the position of the clamp itself is determined according to the actual position of the final assembly, therefore, when the longitudinal beam 100 and the positioning adjusting piece 200 are clamped on the clamp, due to the existence of cumulative tolerance, the position of the positioning adjusting piece 200 relative to the longitudinal beam 100 can be moved, that is, the first positioning hole 130 and the second positioning hole 210 can be eccentrically arranged, and the positioning adjusting piece 200 will also be moved to a certain position of the pre-hanging hole group 120.
[0029] After that, the positioning adjusting piece 200 is welded to the longitudinal beam 100 along the R-axis direction, and the installation and positioning between the fender and the longitudinal beam 100, the installation and positioning between the engine cover and the longitudinal beam 100, the installation and positioning of the front end module on the vehicle body when self-positioning, and the installation and positioning of the tool on the vehicle body when the front end module is assembled by the tool, all take the second positioning hole 210 as the positioning reference, so that the assembly reference of all important parts of the front face component of the vehicle body is kept consistent.
[0030] Compared with the prior art, the scheme directly establishes an adjustable first-level positioning structure on the longitudinal beam 100, reduces the cumulative error of the traditional scheme through multi-level transfer positioning, and further, the projection coverage design ensures that the two holes are always in complete communication state during welding, thereby providing protection for the final precise positioning.
[0031] Further, the application realizes the hierarchical simplification of the assembly reference of the front face component, integrates the positioning functions originally dispersed on the longitudinal beam 100 and the fender into a single adjustable structure, and reduces the operation complexity without repeatedly adjusting the cooperation relationship between multiple components in the assembly process. The direct welding and fixing mode of the positioning adjusting piece 200 and the longitudinal beam 100 not only guarantees the final positioning accuracy, but also improves the overall structural stability through rigid connection.
[0032] In an embodiment, the R-axis direction is a vertical direction, the longitudinal beam 100 includes a mounting plate 110 arranged at an upper end, a mounting surface 111 is an upper end surface of the mounting plate 110, and the pre-hanging hole group 120 and the first positioning hole 130 are arranged on the mounting plate 110.
[0033] It should be noted that the mounting surface 111 can be a flat surface or a curved surface with a certain degree of curvature.
[0034] The mounting plate 110 refers to the planar structure set on the upper end of the longitudinal beam 100. It can be made by stamping a steel plate with a thickness of 1.5-3mm. Its function is to provide a stable mounting base for the pre-hanging hole group 120 and the first positioning hole 130. The pre-hanging hole group 120 refers to the collection of through holes distributed on the mounting plate 110 for connecting the positioning adjustment component 200. It can be made by stamping oblong or waist-shaped holes, and its function is to provide multi-directional adjustment space for the positioning adjustment component 200. The first positioning hole 130 refers to the reference positioning hole set on the mounting plate 110. It can be made by laser cutting a circular hole, and its function is to form a positioning reference with the second positioning hole 210 of the positioning adjustment component 200.
[0035] Specifically, the mounting plate 110 serves as the upper load-bearing structure of the longitudinal beam 100. Its planar upper surface forms the mounting reference, and both the pre-mounted hole group 120 and the first positioning hole 130 are integrated onto the mounting plate 110. The positioning adjustment component 200 achieves bidirectional position adjustment along the P-axis and Q-axis through the pre-mounted hole group 120, while the first positioning hole 130 always maintains a projected overlap relationship with the second positioning hole 210. The planar structure of the mounting plate 110 not only provides a precise machining reference for each positioning feature but also effectively disperses assembly stress through the rigidity of the plate itself.
[0036] Furthermore, in one embodiment, the pre-mounted hole group 120 includes a first adjustment hole 121 and a second adjustment hole 122, which are distributed along the Q axis on both sides of the first positioning hole 130.
[0037] Furthermore, in one embodiment, both the first adjustment hole 121 and the second adjustment hole 122 are rectangular holes.
[0038] Specifically, after the first adjusting hole 121 and the second adjusting hole 122 are respectively set as rectangular holes, their long side direction can be arranged corresponding to the P-axis or the Q-axis. When the first bent section 230 or the second bent section 250 of the positioning adjusting member 200 is inserted into the rectangular hole, the first bent section 230 or the second bent section 250 forms a clearance fit with the hole wall in the long side direction, allowing displacement adjustment in this direction; while in the short side direction, the limiting is achieved by the contact between the hole wall and the side of the first bent section 230 or the second bent section 250.
[0039] However, this is not the only one. In other embodiments, the first adjustment hole 121 and the second adjustment hole 122 may also be elliptical holes, waist-shaped holes or other shapes of holes, which will not be listed here.
[0040] Specifically, when the first adjusting hole 121 and the second adjusting hole 122 are both rectangular holes, the long side direction of the first adjusting hole 121 is the same as the Q-axis direction, the short side direction of the first adjusting hole 121 is the same as the P-axis direction, or the long side direction of the first adjusting hole 121 is the same as the P-axis direction, and the short side direction of the first adjusting hole 121 is the same as the Q-axis direction. The long side direction of the second adjusting hole 122 is the same as the Q-axis direction, the short side direction of the second adjusting hole 122 is the same as the P-axis direction, or the long side direction of the second adjusting hole 122 is the same as the P-axis direction, and the short side direction of the second adjusting hole 122 is the same as the Q-axis direction.
[0041] Further, in an embodiment, the pre-hanging hole set 120 further comprises a first assembly hole 123 and a second assembly hole 124. The first assembly hole 123 is arranged at one end of the first adjusting hole 121, and the first assembly hole 123 and the first adjusting hole 121 are in communication to form a first L-shaped structure. Specifically, one end of the first assembly hole 123 is in communication with the first adjusting hole 121, and the other end extends towards a direction away from the first positioning hole 130. The second assembly hole 124 is arranged at one end of the second adjusting hole 122, and the second assembly hole 124 and the second adjusting hole 122 are in communication to form a second L-shaped structure. The first structure and the second structure are arranged in mirror symmetry along the Q-axis direction. Specifically, one end of the second assembly hole 124 is in communication with the second adjusting hole 122, and the other end extends towards a direction away from the first positioning hole 130.
[0042] However, the first assembly hole 123 can also be in communication with the first adjusting hole 121 at the middle part, one end of the first assembly hole 123 extends towards a direction away from the first positioning hole 130, and the other end extends towards a direction close to the first positioning hole 130, and the first assembly hole 123 and the first adjusting hole 121 form a T-shaped structure. Similarly, the second assembly hole 124 can also be in communication with the second adjusting hole 122 at the middle part, one end of the second assembly hole 124 extends towards a direction away from the first positioning hole 130, and the other end extends towards a direction close to the first positioning hole 130, and the second assembly hole 124 and the second adjusting hole 122 form a T-shaped structure.
[0043] In an embodiment, one end of the positioning adjusting member 200 is inserted into the first adjusting hole 121, and the other end of the positioning adjusting member 200 is movably limited in the first adjusting hole 121 along the Q-axis direction, that is, one end of the positioning adjusting member 200 can move in the first adjusting hole 121 along the Q-axis direction, and the movement range of the positioning adjusting member 200 is limited by the side walls at both ends of the first adjusting hole 121 along the Q-axis direction, preventing the positioning adjusting member 200 from being separated from the first adjusting hole 121.
[0044] And, one end of the positioning adjustment piece 200 and the first adjustment hole 121 are movably limited in position along the P-axis, that is, one end of the positioning adjustment piece 200 can move along the P-axis within the first adjustment hole 121, and the movement range of the positioning adjustment piece 200 is limited by the blocking of the two end side walls of the first adjustment hole 121 along the P-axis, preventing the positioning adjustment piece 200 from leaving the first adjustment hole 121.
[0045] The other end of the positioning adjustment piece 200 is inserted into the second adjustment hole 122 and movably limited in position along the Q-axis, that is, the other end of the positioning adjustment piece 200 can move along the Q-axis within the second adjustment hole 122, and the movement range of the positioning adjustment piece 200 is limited by the blocking of the two end side walls of the second adjustment hole 122 along the Q-axis, preventing the positioning adjustment piece 200 from leaving the second adjustment hole 122.
[0046] And, the other end of the positioning adjustment piece 200 and the second adjustment hole 122 are movably limited in position along the P-axis, that is, the other end of the positioning adjustment piece 200 can move along the P-axis within the second adjustment hole 122, and the movement range of the positioning adjustment piece 200 is limited by the blocking of the two end side walls of the second adjustment hole 122 along the P-axis, preventing the positioning adjustment piece 200 from leaving the second adjustment hole 122.
[0047] Wherein, the Q-axis and the P-axis refer to two directions perpendicular to each other, and the positioning compensation is achieved by double-axis adjustment. The movably limited in position cooperation refers to the structural relationship that the parts can move within the hole but are limited by the hole wall. The two adjustment holes (including the first adjustment hole 121 and the second adjustment hole 122) symmetrically distributed on both sides of the first positioning hole 130 can be realized by using a symmetrical layout structure, forming a two-way adjustment reference to balance the assembly stress.
[0048] Specifically, the positioning adjustment piece 200 can be adjusted in position along the P-axis and the Q-axis. For example, on the mounting surface 111 of the longitudinal beam 100, the first adjustment hole 121 and the second adjustment hole 122 are respectively located on the left and right sides of the first positioning hole 130, forming a transversely symmetrical layout. After the positioning adjustment piece 200 is inserted into the first adjustment hole 121 and the second adjustment hole 122, its two ends are respectively constrained by the hole walls along the transverse and longitudinal directions, so that the positioning adjustment piece 200 can be calibrated in position according to the actual assembly requirements before welding. And, the second positioning hole 210 and the first positioning hole 130 can always keep projection coincidence during final welding, avoiding positioning failure caused by assembly error.
[0049] Further, in an embodiment, the positioning adjusting piece 200 comprises a first hooking section 220, a first bending section 230, a main plate section 240, a second bending section 250, and a second hooking section 260, and the second positioning hole 210 is arranged on the main plate section 240; one end of the first bending section 230 and one end of the second bending section 250 are respectively connected to two ends of the main plate section 240 arranged opposite to each other along the Q-axis, and the other end of the first bending section 230 and the other end of the second bending section 250 respectively extend along the R-axis to the direction away from the main plate section 240; one end of the first hooking section 220 is connected to the end of the first bending section 230 away from the main plate section 240, and one end of the second hooking section 260 is connected to the end of the second bending section 250 away from the main plate section 240, and the end of the first hooking section 220 away from the first bending section 230 and the end of the second hooking section 260 away from the second bending section 250 respectively extend along the Q-axis to the direction away from each other. As known from the above, the positioning adjusting piece 200 has a structure in the shape of approximately "Ji" character.
[0050] When the positioning adjusting piece 200 and the pre-hanging hole group 120 are assembled, the first hooking section 220 can pass through the first assembly hole 123 to the lower end surface of the mounting plate 110 and be clamped thereon, the first bending section 230 can be arranged in the first adjusting hole 121, and the first bending section 230 can be movably limited in the first adjusting hole 121 along the P-axis and the Q-axis. The second hooking section 260 can pass through the second assembly hole 124 to the lower end surface of the mounting plate 110 and be clamped thereon, the second bending section 250 can be arranged in the second adjusting hole 122, and the second bending section 250 can be movably limited in the second adjusting hole 122 along the P-axis and the Q-axis.
[0051] Among them, the first L-shaped structure refers to a right-angle broken line hole formed by the communication between the first adjusting hole 121 and the first assembly hole 123, which can be realized by arranging two mutually perpendicular strip-shaped holes on the mounting plate 110. The first bending section 230 and the second bending section 250 refer to metal parts with spatial bending structure, which can be processed into a shape with 90-degree bending by bending process. The first hooking section 220 and the second hooking section 260 can realize the pre-fixing of the positioning adjusting piece 200 in a non-welding state.
[0052] The present scheme utilizes the spatial cooperation relationship between the L-shaped hole structure and the positioning adjusting piece 200 to enable the positioning adjusting piece 200 to move freely along two axes during installation, and prevents the positioning adjusting piece 200 from being separated through the hooking action of the first hooking section 220 and the second hooking section 260.
[0053] Further, in an embodiment, the maximum distance A of the first bending section 230 moving along the P-axis in the first adjusting hole 121 satisfies 1mm≤A≤5mm, and preferably A is equal to 3mm.
[0054] Correspondingly, the maximum distance B of the first bending segment 230 moving along the Q-axis within the first adjusting hole 121 satisfies 1mm≤B≤5mm, preferably, B equals to 3mm.
[0055] Similarly, the maximum distance M of the second bending segment 250 moving along the P-axis within the second adjusting hole 122 satisfies 1mm≤M≤5mm, preferably, M equals to 3mm.
[0056] Correspondingly, the maximum distance N of the second bending segment 250 moving along the Q-axis within the second adjusting hole 122 satisfies 1mm≤N≤5mm, preferably, N equals to 3mm.
[0057] Wherein, the maximum distance A refers to the limit distance of the first bending segment 230 moving along the P-axis, which can be realized by the difference between the length of the adjusting hole (including the first adjusting hole 121 and the second adjusting hole 122) and the size of the bending segment (including the first bending segment 230 and the second bending segment 250). The maximum distance B refers to the limit distance of the first bending segment 230 moving along the Q-axis, which can be realized by the difference between the width of the adjusting hole and the size of the bending segment. The maximum distances M and N are defined similarly as A and B, but they act on the second bending segment 250 and are realized by symmetric arrangement to achieve bidirectional balanced adjustment.
[0058] Specifically, in the assembly process, the cooperation of the first bending segment 230 and the first adjusting hole 121 allows controllable displacement along the P-axis and the Q-axis, for example, when A is set to 3mm, the longitudinal adjustment stroke can be limited within the error allowable range. The cooperation of the second bending segment 250 and the second adjusting hole 122 adopts the same displacement restriction mechanism, so that when the positioning adjusting piece 200 moves on the mounting surface 111, the projection covering relationship between the first positioning hole 130 and the second positioning hole 210 is always guaranteed. This design of displacement range not only avoids positioning deviation caused by excessive movement, but also reserves the necessary assembly allowance.
[0059] In an embodiment, the first hook segment 220, the first bending segment 230, the main plate segment 240, the second bending segment 250 and the second hook segment 260 are integrally and bendedly formed metal pieces.
[0060] The integral bending forming refers to continuous processing of multiple structure sections into a whole through a single sheet metal bending process. Specifically, a stamping die or a bending machine can be used to continuously bend the metal plate, so that the structure sections are connected without welding or riveting. This process can eliminate the cumulative error caused by the assembly of the split structure, and reduce the risk of welding thermal deformation. The sheet metal part refers to a structure part processed from a metal sheet. Specifically, a low-carbon steel or aluminum alloy plate can be selected, for example, with a thickness ranging from 0.8 to 2.0 millimeters. The material selection can ensure the structural strength while meeting the lightweight requirements.
[0061] However, the first hook section 220, the first bending section 230, the main plate section 240, the second bending section 250, and the second hook section 260 can also be castings integrally cast, or the first hook section 220, the first bending section 230, the main plate section 240, the second bending section 250, and the second hook section 260 can also be welded parts.
