Specific implementation

[0039] In order to make the purpose, technical scheme and advantages of the utility model embodiments clearer, the technical scheme in the utility model embodiments will be described clearly and completely below in combination with the drawings in the utility model embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0040] In the related art, the front end frame is connected with the beam body of the vehicle through the connecting piece. Specifically, one end of the connecting piece is connected with the top wall of the beam body, and the other end of the connecting piece is connected with the side wall of the front end frame. The connecting piece is usually provided as a connecting plate. The structural strength of the connecting piece is insufficient, and deformation is likely to occur, which in turn leads to the problem that the front end frame may be displaced or slid.

[0041] In order to solve or improve the problem of insufficient structural strength of the connecting piece in the related art, the utility model embodiments provide a connecting piece, a front end frame mounting structure and a vehicle.

[0042] The embodiments of the utility model will be described below in combination with Figures 1 to 11 The connecting piece 1 provided in the embodiments of the utility model is described.

[0043] Specifically, the connecting piece 1 is used to connect the front end frame 2 and the beam body 3. The connecting piece 1 comprises a supporting part 103, a first connecting part 101 and a second connecting part 102.

[0044] The support part 103 is used to be connected with the front end frame 2. Optionally, the support part 103 is supported on the bottom of the front end frame 2 and connected with the bottom of the front end frame 2. Optionally, the support part 103 is detachably connected with the front end frame 2 through a threaded fastener. Of course, in some embodiments not shown, the support part 103 can also be connected to the side wall or top of the front end frame 2.

[0045] The first connecting part 101 and the second connecting part 102 are both connected with the support part 103, and the first connecting part 101 and the second connecting part 102 are oppositely arranged. Optionally, the first connecting part 101 and the second connecting part 102 are both arranged on the same side of the support part 103, for example, the first connecting part 101 and the second connecting part 102 are both arranged on the bottom or top of the support part 103.

[0046] The first connecting part 101 and the second connecting part 102 are arranged on opposite sides of the beam body 3 and are respectively connected with the two side walls of the beam body 3. Optionally, the first connecting part 101 and the second connecting part 102 are both detachably connected with the beam body 3 through corresponding threaded fasteners.

[0047] In this embodiment, the first connecting part 101 and the second connecting part 102 are connected with the support part 103 and are respectively connected on the two sides of the beam body 3, so that the connecting piece 1 forms a closed frame structure, thereby when subjected to external load, the load can be dispersed to the entire frame structure, avoiding stress concentration in some positions, so that the connecting piece 1 has better rigidity, preventing the connecting piece 1 from deforming, and further making the connecting piece 1 can provide more stable fixing effect for the front end frame 2.

[0048] In the related art, one end of the connecting piece 1 is connected to the beam body 3, and a relatively high stress concentration may occur at the connection point, especially in the case of bearing a large load, the problem of stress concentration is more obvious. In this embodiment, the support part 103 is connected with the beam body 3 through the first connecting part 101 and the second connecting part 102, so that the stress can be dispersed to the first connecting part 101 and the second connecting part 102, effectively reducing the stress level of a single connection point, thereby improving the overall stability and durability of the connecting piece 1.

[0049] In addition, in this embodiment, the support part 103 can be supported on the bottom of the front end frame 2, that is, during the installation of the front end frame 2, the front end frame 2 is hoisted on the support part 103, and the support part 103 can limit the front end frame 2 in the vertical direction. Then, the position of the front end frame 2 can be adjusted horizontally, without the need to repeatedly adjust the position of the front end frame 2 in the vertical direction, thereby making the installation of the front end frame 2 more convenient.

[0050] Reference Figures 3-5As shown, in some embodiments provided by the utility model, the support part 103, the first connecting part 101 and the second connecting part 102 are all provided as plate body structures, and the first connecting part 101 and the second connecting part 102 are respectively connected to opposite edges of the support part 103. That is, the support part 103, the first connecting part 101 and the second connecting part 102 enclose a U-shaped frame, and the U-shaped frame is sleeved outside the beam body 3.

[0051] In the embodiment, the support part 103, the first connecting part 101 and the second connecting part 102 enclose a U-shaped frame, so that the whole connecting piece 1 forms a closed structure, thereby improving the rigidity of the connecting piece 1. In addition, the U-shaped frame can more evenly disperse external loads to each part of the frame, avoiding stress concentration on a certain point, thereby improving the overall strength and rigidity of the connecting piece 1.

[0052] In addition, the U-shaped frame is connected to both sides of the beam body 3 through the first connecting part 101 and the second connecting part 102, respectively, which can provide multiple constraint points for the connecting piece 1, which can not only enhance the firmness of the connection between the connecting piece 1 and the beam body 3, but also effectively transfer and disperse loads, reducing the burden of a single connection point.

[0053] In some embodiments provided by the utility model, the support part 103, the first connecting part 101 and the second connecting part 102 are provided as sheet metal integrated structures.

[0054] In the embodiment, the sheet metal integrated structure can eliminate the connection points between different components, reduce potential stress concentration areas, so that the whole connecting piece 1 has higher overall rigidity and strength, and can better resist external loads.

[0055] In addition, the sheet metal integrated structure can be formed by one-time molding through processes such as stamping and bending, which can ensure the position accuracy and dimensional accuracy of each component, thereby improving the manufacturing accuracy of the connecting piece 1. In addition, since no additional assembly steps are required, the integrated structure can greatly shorten the production cycle, improve production efficiency and reduce manufacturing costs.

[0056] Reference Figures 8-11 As shown, in some embodiments provided by the utility model, the surface of at least one of the first connecting part 101 and the second connecting part 102 is provided with a first reinforcing rib 105, and at least part of the first reinforcing rib 105 is located at the connection between the first connecting part 101 or the second connecting part 102 and the support part 103.

[0057] In the embodiment, by providing the first reinforcing rib 105 on the surface of the first connecting part 101 or the second connecting part 102, the rigidity of the first connecting part 101 or the second connecting part 102 can be improved, and the problem of deformation of the first connecting part 101 and the second connecting part 102 can be avoided, thereby increasing the overall strength of the connecting piece 1.

[0058] In addition, by arranging the first reinforcing rib 105 at the connection between the first or second connecting part 101, 102 and the support part 103, the local rigidity of the connection between the first or second connecting part 101, 102 and the support part 103 can be significantly increased, making it more difficult for this part to deform, thereby increasing the overall strength of the connecting piece 1.

[0059] Optionally, the first reinforcing rib 105 is arranged as a stamping rib. Specifically, the stamping rib is a protruding structure formed on the surface of the first or second connecting part 101, 102 by a stamping process.

[0060] In this embodiment, by arranging the first reinforcing rib 105 as a stamping rib, not only can the production efficiency, structural strength and rigidity be significantly improved, but also the precision and consistency of the first reinforcing rib 105 can be improved.

[0061] Optionally, the first reinforcing rib 105 is arranged on the surface of both the first and second connecting parts 101, 102, and the first reinforcing rib 105 on the first connecting part 101 is arranged at the connection between the first connecting part 101 and the support part 103, and the first reinforcing rib 105 on the second connecting part 102 is arranged at the connection between the second connecting part 102 and the support part 103.

[0062] In this embodiment, by arranging the first reinforcing rib 105 on the first and second connecting parts 101, 102 respectively, the rigidity of the first and second connecting parts 101, 102 can be improved respectively, avoiding the problem of deformation of the first and second connecting parts 101, 102, thereby increasing the overall strength of the connecting piece 1.

[0063] In addition, the first reinforcing rib 105 is arranged at the connection between the connecting part and the support part 103, which can improve the rigidity of the connection between the connecting part and the support part 103, avoiding the problem of deformation of the connection between the connecting part and the support part 103.

[0064] Optionally, for the first reinforcing rib 105 on the first connecting part 101, the first reinforcing rib 105 can protrude from the surface of the first connecting part 101 away from the second connecting part 102, or protrude from the surface of the first connecting part 101 towards the second connecting part 102.

[0065] Correspondingly, for the first reinforcing rib 105 on the second connecting part 102, the first reinforcing rib 105 can protrude from the surface of the second connecting part 102 away from the first connecting part 101, or protrude from the surface of the second connecting part 102 towards the first connecting part 101.

[0066] Reference Figures 3-5As shown, in some embodiments of the utility model, the surface of the support part 103 is provided with a second reinforcing rib 106. The second reinforcing rib 106 is at least partially located at the connection between the support part 103 and the first connecting part 101 or the second connecting part 102.

[0067] In this embodiment, by providing the second reinforcing rib 106 on the surface of the support part 103, the rigidity of the support part 103 can be improved, and the problem of deformation of the support part 103 can be avoided, thereby increasing the overall strength of the connecting piece 1.

[0068] In addition, by locating the second reinforcing rib 106 at the connection between the support part 103 and the first connecting part 101 or the second connecting part 102, the local rigidity of the connecting part of the support part 103 and the first connecting part 101 or the second connecting part 102 can be significantly increased, making it more difficult for this part to deform, thereby increasing the overall strength of the connecting piece 1.

[0069] Optionally, the second reinforcing rib 106 is provided as a punched reinforcing rib. Specifically, the punched reinforcing rib is a protruding structure formed on the surface of the support part 103 by a punching process.

[0070] In this embodiment, by providing the second reinforcing rib 106 as a punched reinforcing rib, not only can the production efficiency, structural strength and rigidity be significantly improved, but also the precision and consistency of the second reinforcing rib 106 can be improved.

[0071] Optionally, it is known that the first connecting part 101 and the second connecting part 102 have a space 104 for the beam body 3 to pass through, then the second reinforcing rib 106 can protrude from the surface of the support part 103 towards the space 104, or can protrude from the surface of the support part 103 away from the space 104.

[0072] Further, with reference to Figure 5 As shown, under the condition that the second reinforcing rib 106 is provided at the connection between the support part 103 and the second connecting part 102, and the first reinforcing rib 105 is provided on the second connecting part 102, one of the first reinforcing rib 105 and the second reinforcing rib 106 protrudes towards the space 104, and the other protrudes away from the space 104, to avoid the problem that the first reinforcing rib 105 and the second reinforcing rib 106 protrude in the same direction, causing excessive stress concentration and cracking.

[0073] Similarly, under the condition that the second reinforcing rib 106 is provided at the connection between the support part 103 and the first connecting part 101, and the first reinforcing rib 105 is provided on the first connecting part 101, one of the first reinforcing rib 105 and the second reinforcing rib 106 protrudes towards the space 104, and the other protrudes away from the space 104, to avoid the problem that the first reinforcing rib 105 and the second reinforcing rib 106 protrude in the same direction, causing excessive stress concentration and cracking.

[0074] Reference Figure 3 As shown in some embodiments provided by the utility model, the second connecting part 102 is provided with a flange 107, the flange 107 is folded towards the direction away from the first connecting part 101, and the flange 107 is provided with a mounting part 1074. For example, the mounting part 1074 is used for mounting corresponding parts. The mounting part 1074 includes but is not limited to mounting holes. Optionally, the parts mounted by the mounting part 1074 include but are not limited to wire harnesses, sensors and pipelines.

[0075] In the embodiment, the connecting piece 1 can provide stable mounting points for the parts such as wire harnesses, sensors and pipelines through the flange 107. For example, through bolts, buckles or other fixing modes, it can ensure that these parts are firmly mounted on the connecting piece 1, and reduce the risk of loosening or falling off.

[0076] Optionally, the flange 107 includes a first flange 1071, a second flange 1072 and a third flange 1073.

[0077] The first flange 1071 and the third flange 1073 are respectively arranged on two adjacent edges of the second connecting part 102, and the second flange 1072 is connected to the edge of the first flange 1071 close to the third flange 1073 and extends by being folded towards the third flange 1073. The second flange 1072 overlaps the third flange 1073.

[0078] In the embodiment, the first flange 1071 and the third flange 1073 are connected to two adjacent edges of the second connecting part 102, and overlap through the third flange 1073, so as to form a stable frame structure, which has high rigidity and stability and can effectively resist external load, thereby providing stable mounting points for the parts such as wire harnesses, sensors and pipelines.

[0079] It can be understood that when the number of the connecting pieces 1 is multiple, the flange 107 can be arranged on all the connecting pieces 1, of course, according to actual installation requirements, the flange 107 can also be arranged on only part of the connecting pieces 1.

[0080] Reference Figure 8 And Figure 10 As shown in some embodiments provided by the utility model, the width of the first connecting part 101 gradually decreases from one end close to the supporting part 103 to the other end away from the supporting part 103. Figure 8 Or Figure 10 As shown, the width of the first connecting part 101 refers to the size of the first connecting part 101 along the left-right direction in the drawing, and can also refer to the size of the first connecting part 101 along the axial direction of the beam body 3.

[0081] In the embodiment, the first connecting part 101 is wider near one end of the supporting part 103, which can provide a larger contact area and stronger bearing capacity, ensure that the external load can be effectively transmitted between the supporting part 103 and the first connecting part 101, help to reduce stress concentration, and improve the overall strength of the connecting piece 1.

[0082] With the increase of the distance from the supporting part 103, the width of the first connecting part 101 gradually decreases, so that the load transmission is more smooth and gradual, and the problem of stress mutation is avoided. In addition, by gradually reducing the width of the first connecting part 101, unnecessary material use can be reduced under the premise of ensuring the bearing capacity, so as to reduce the self-weight of the whole connecting piece 1.

[0083] In some embodiments not shown, the width of the second connecting part 102 gradually decreases from the end near the supporting part 103 to the end away from the supporting part 103. The width of the second connecting part 102 refers to the dimension of the second connecting part 102 in the axial direction of the beam body 3.

[0084] In the embodiment, the second connecting part 102 is wider near one end of the supporting part 103, which can provide a larger contact area and stronger bearing capacity, ensure that the external load can be effectively transmitted between the supporting part 103 and the second connecting part 102, help to reduce stress concentration, and improve the overall strength of the connecting piece 1.

[0085] With the increase of the distance from the supporting part 103, the width of the second connecting part 102 gradually decreases, so that the load transmission is more smooth and gradual, and the problem of stress mutation is avoided. In addition, by gradually reducing the width of the second connecting part 102, unnecessary material use can be reduced under the premise of ensuring the bearing capacity, so as to reduce the self-weight of the whole connecting piece 1.

[0086] In some embodiments of the utility model, the first connecting part 101 is provided with at least one first connecting hole 108, and the second connecting part 102 is provided with at least two second connecting holes 109, and the first connecting hole 108 and the second connecting hole 109 are used for being connected with the beam body 3. Optionally, the first connecting hole 108 and the second connecting hole 109 are used for being passed through by a threaded fastener. Optionally, the first connecting part 101 is provided with one first connecting hole 108, and the second connecting part 102 is provided with two second connecting holes 109.

[0087] In the embodiment, by arranging at least one first connecting hole 108 on the first connecting part 101 and at least two second connecting holes 109 on the second connecting part 102, the number of connecting holes can be reduced under the premise of avoiding rotation of the connecting piece 1 around the axis of the connecting hole, thereby reducing the area, weight and processing difficulty of the connecting piece 1, and reducing the number of threaded fasteners required for installing the connecting piece 1, so as to reduce the installation difficulty of the connecting piece 1 and the cost of the vehicle.

[0088] Optionally, the first connecting part 101 is connected to the inner side of the beam body 3, and the second connecting part 102 is connected to the outer side of the beam body 3. The inner side of the beam body 3 can be understood as the side of the beam body 3 close to the center of the vehicle, and the outer side of the beam body 3 can be understood as the side of the beam body 3 away from the center of the vehicle.

[0089] In the embodiment, since the number of first connecting holes 108 on the first connecting part 101 is small and the number of second connecting holes 109 on the second connecting part 102 is large, connecting the first connecting part 101 to the inner side of the beam body 3 can reduce the number of threaded fasteners installed on the inner side of the beam body 3, thereby reducing the installation difficulty of the connecting piece 1.

[0090] In some embodiments provided by the utility model, the support part 103 is provided with a third connecting hole 110, and the third connecting hole 110 is used for being connected with the front end frame 2. For example, the third connecting hole 110 is used for being penetrated by a threaded fastener, and the threaded fastener penetrates the third connecting hole 110 and is connected with the front end frame 2.

[0091] In some embodiments provided by the utility model, the support part 103 is provided with a positioning hole 111, and the positioning hole 111 is used for limiting the front end frame 2 in the direction perpendicular to the axial direction of the positioning hole 111. For example, the front end frame 2 is provided with a positioning protrusion, and the positioning protrusion is used for limiting cooperation with the positioning hole 111.

[0092] In the embodiment, by arranging the positioning hole 111 on the support part 103, the front end frame 2 is limited, which can not only ensure the position accuracy of the front end frame 2, but also reduce the movement of the front end frame 2 in the direction perpendicular to the axial direction of the positioning hole 111, thereby improving the stability of the front end frame 2.

[0093] Optionally, the positioning hole 111 is a square hole. In the embodiment, the square hole can provide accurate limiting for the front end frame 2 in two orthogonal directions, which can not only limit the movement of the front end frame 2 in the direction perpendicular to the axial direction of the positioning hole 111, but also effectively prevent the rotation of the front end frame 2 in the plane perpendicular to the axial direction of the positioning hole 111, thereby making the installation position of the front end frame 2 more stable and reliable.

[0094] Optionally, when the number of the connecting pieces 1 is multiple, positioning holes 111 can be arranged on all the connecting pieces 1, of course, positioning holes 111 can also be arranged on only part of the connecting pieces 1 according to actual installation requirements.
