Description

Technical Field

[0001] The present application relates to but is not limited to the field of mounting structures, and in particular to a mounting structure of a vehicle body and a vehicle. Background Art

[0002] In order to reduce the energy consumption of vehicles, one-piece cast aluminum alloy bodies are widely used in vehicles. The body needs to bear a large number of body parts, so a plurality of mounting holes for mounting body parts need to be provided on the body. However, the strength of aluminum alloy is relatively low and the dynamic load it can withstand is relatively small. Therefore, in the related art, the mounting holes of the body are easily deformed and it is difficult for the body parts to be stably mounted at the mounting holes of the body. Utility Model Content

[0003] The mounting structure of the vehicle body provided in the embodiment of the present application can improve the stability of the installation of the vehicle body parts at the mounting holes of the vehicle body, and can also prevent the mounting holes of the vehicle body from being easily deformed.

[0004] In the first aspect, an embodiment of the present application provides a mounting structure of a vehicle body, comprising a vehicle body main body and a mounting member, wherein the vehicle body main body is provided with a mounting hole; the mounting member is embedded in the mounting hole, and the mounting member is provided with a through hole that penetrates the mounting member along the axial direction of the mounting hole, and the through hole is used to install vehicle body parts; a protrusion is provided on the outer periphery of the mounting member, and the protrusion is interference fit with the inner periphery of the mounting hole.

[0005] In the mounting structure of the vehicle body provided by the embodiment of the present application, the mounting piece is sleeved in the mounting hole of the vehicle body, and the vehicle body parts are mounted in the through hole of the mounting piece, so that the vehicle body parts are mounted on the vehicle body through the mounting piece, and the outer periphery of the mounting piece is interference fit with the mounting hole of the vehicle body at the protrusion, so as to improve the stability of the mounting piece at the mounting hole of the vehicle body, thereby improving the stability of the vehicle body parts at the mounting hole of the vehicle body. In addition, since the outer periphery of the mounting piece is interference fit with the mounting hole only in the local area where the protrusion is provided, it is possible to reduce the excessive extrusion of the outer periphery of the mounting piece on the inner periphery of the mounting hole, thereby reducing the deformation of the mounting hole caused by excessive extrusion, so that the mounting hole of the vehicle body is not easily deformed. Therefore, compared with the method of directly installing the body parts in the mounting holes of the body in the related art, the outer periphery of the mounting part of the present application is interference fit with the mounting hole in the local area where the protrusion is provided, so as to improve the stability of the mounting part in the mounting hole of the body, thereby improving the stability of the body parts in the mounting hole of the body, and reducing the deformation caused by excessive extrusion of the outer periphery of the mounting part on the inner periphery of the mounting hole, so that the mounting hole of the body is not easy to deform. In addition, the body parts are installed in the mounting holes of the body through the mounting parts, so that the body parts will not directly contact the mounting holes of the body, so the force on the body parts will not be directly transmitted to the mounting holes of the body, so that the mounting holes of the body are not easy to deform.

[0006] In a possible implementation of the present application, the outer periphery of the mounting member includes a plurality of contour surfaces, the plurality of contour surfaces are sequentially connected end to end along the circumference of the mounting member, and two adjacent contour surfaces are protruded near the connection position to form a protrusion.

[0007] Here, the arrangement of the protrusions in this way makes the outer periphery of the mounting member smoother, thereby making the process of the mounting member being embedded in the mounting hole of the vehicle body smoother.

[0008] In a possible implementation of the present application, the curvature of each contour surface and the size of each contour surface in the circumferential direction of the mounting member are equal, so that the mounting member is rotationally symmetric along the central axis of the through hole.

[0009] Here, the mounting piece is rotationally symmetrical along the central axis of the through hole, so that when the mounting piece is embedded in the mounting hole of the vehicle body, the extrusion force on the inner periphery of the mounting hole is more uniform, thereby further making it difficult for the mounting hole to deform.

[0010] In a possible implementation of the present application, the mounting member includes a rod and an end portion, the end portion is arranged at one end of the rod portion along the axial direction of the mounting hole, and the radial dimension of the rod portion is smaller than the radial dimension of the end portion; the protrusion is arranged on the outer periphery of the rod portion.

[0011] Here, in this arrangement of the mounting piece, the protrusion on the outer periphery of the rod is interference fit with the inner periphery of the mounting hole to firmly mount the mounting piece in the mounting hole of the vehicle body, and the end portion can axially limit the mounting piece, thereby improving the reliability of the mounting piece in the mounting hole.

[0012] In a possible implementation of the present application, an end surface of the other end of the rod away from the end portion smoothly transitions to an outer circumferential surface of the rod.

[0013] Here, the end face of the other end of the rod away from the end portion is the starting end face when the mounting piece is embedded in the mounting hole. Therefore, the smooth transition between the end face of the other end of the rod away from the end portion and the outer peripheral surface of the rod can reduce the excessive extrusion of the starting end face of the mounting piece on the inner periphery of the mounting hole, making it less likely for deformation to occur at the mounting hole of the vehicle body.

[0014] In a possible implementation of the present application, the end portion includes a plurality of side planes, the plurality of side planes are sequentially connected end to end along the circumference of the mounting member, and a connection position of two adjacent side planes is smoothly transitioned.

[0015] Here, at least part of the outer circumference of the end cooperates with the inner circumference of the mounting hole, so the multiple side planes constituting the outer circumference of the end smoothly transition at adjacent connection positions, making the outer circumference of the end relatively smooth, thereby making the process of embedding the end into the mounting hole of the vehicle body smoother.

[0016] In a possible implementation of the present application, a first angle is formed between the axial direction of the through hole and the radial direction of the end portion, and the first angle is set between 0°-180°.

[0017] Here, by adjusting the angle of the first angle, the end portion and the rod portion can form different inclination angles to meet the installation requirements of vehicle body parts with different inclination angles, and since the mounting piece and the vehicle body are manufactured separately, the angle of the first angle can be adjusted without changing the inclination angle of the mounting hole of the vehicle body. Vehicle body parts with different inclination angles can be installed on the vehicle body with the same mounting hole through mounting pieces with different first angles, thereby facilitating the production and manufacturing of the vehicle body.

[0018] In a possible implementation of the present application, the vehicle body is made of a first material, the mounting member is made of a second material, and the hardness of the second material is greater than the hardness of the first material.

[0019] Here, this arrangement makes it difficult for the mounting piece on which the vehicle body parts are mounted to be deformed, thereby further making it difficult for the mounting hole of the vehicle body to be deformed, thereby improving the strength of the vehicle body at the mounting hole.

[0020] In a possible implementation of the present application, the first material is an aluminum alloy material, and the second material is an iron alloy material.

[0021] Here, the first material is aluminum alloy material with the advantage of light weight to meet the lightweight requirements of the vehicle body, and the second material is iron alloy material with the advantages of high strength and easy production and processing, so as to improve the strength of the vehicle body at the mounting hole while also facilitating the production of mounting parts.

[0022] In a second aspect, an embodiment of the present application provides a vehicle, comprising any one of the vehicle body mounting structures in the first aspect.

[0023] The vehicle provided by the embodiment of the present application includes the mounting structure of the vehicle body provided by the first aspect, and thus can achieve the same effect, that is, the vehicle body parts are mounted on the vehicle body through the mounting parts, and the outer periphery of the mounting parts is interference fit with the mounting holes in the local area where the protrusions are provided, so as to improve the stability of the mounting parts installed in the mounting holes of the vehicle body, thereby improving the stability of the vehicle body parts installed at the mounting holes of the vehicle body, and can also reduce the deformation caused by excessive squeezing of the outer periphery of the mounting parts on the inner periphery of the mounting holes, so that the mounting holes of the vehicle body are not easily deformed. In addition, the vehicle body parts are mounted in the mounting holes of the vehicle body through the mounting parts, so that the vehicle body parts will not directly contact the mounting holes of the vehicle body, so the force on the vehicle body parts will not be directly transmitted to the mounting holes of the vehicle body, so that the mounting holes of the vehicle body are not easily deformed.

[0040] With the rapid popularization of new energy vehicles, people's energy consumption requirements for new energy vehicles are becoming more and more stringent, which has led to the extensive application of lightweight one-piece casting technology in vehicles. The car body needs to carry a large number of body parts, so a number of mounting holes for mounting body parts need to be set on the car body. However, the main material used in one-piece casting technology is aluminum alloy. The strength of one-piece casting aluminum alloy is relatively low and can withstand a small dynamic load. Therefore, in the related technology, the mounting holes of the aluminum alloy car body are prone to deformation, and the body parts are difficult to be firmly installed at the mounting holes of the car body.

[0041] In view of this, see Figure 1 , Figure 2 as well as Figure 3 The embodiment of the present application provides a mounting structure of a vehicle body, including a vehicle body 1 and a mounting member 2, wherein the vehicle body 1 is provided with a mounting hole 11; the mounting member 2 is embedded in the mounting hole 11, and the mounting member 2 is provided with a through hole 21 penetrating the mounting member 2 along the axial direction X of the mounting hole 11, and the through hole 21 is used to mount vehicle body parts; a protrusion 22 is provided on the outer periphery of the mounting member 2, and the protrusion 22 is interference fit with the inner periphery of the mounting hole 11.

[0042] In the embodiment of the present application, the shape of the through hole 21 on the mounting member 2 can be set to be cylindrical, prismatic, etc., and can be specifically designed according to the shape of the vehicle body part to be installed in the through hole 21.

[0043] In the embodiment of the present application, the number of mounting holes 11 provided on the vehicle body 1 may be one or more, and a mounting member 2 is respectively embedded in each mounting hole 11, so that one or more vehicle body parts are connected to the vehicle body 1 through the mounting member 2. When the number of mounting holes 11 provided on the vehicle body 1 is more than one, the radial dimensions of the plurality of mounting holes 11 may be the same or different.

[0044] When the radial dimensions of the plurality of mounting holes 11 are the same, the processing and manufacturing of the vehicle body 1 can be facilitated. At this time, since the vehicle body parts are mounted at the mounting holes 11 of the vehicle body 1 through the mounting member 2, the radial dimensions of the through holes 21 on the mounting member 2 for mounting the vehicle body parts can be changed, so that the vehicle body parts with different radial dimensions can be mounted at the plurality of mounting holes 11 with the same radial dimensions on the vehicle body 1 through the mounting member 2. It should be noted that under this arrangement, the outer periphery of the mounting member 2 that matches the inner periphery of the mounting hole 11 remains unchanged, and only the radial dimensions of the through holes 21 on the mounting member 2 for mounting the vehicle body parts are changed, so that the vehicle body parts with different radial dimensions can be mounted at the plurality of mounting holes 11 with the same radial dimensions on the same vehicle body 1.

[0045] In the embodiment of the present application, the cross-sectional shape of the mounting member 2 along the axial direction X of the through hole 21 can be rectangular, T-shaped or other shapes, which can be specifically set according to actual needs, and the shape of the mounting hole 11 of the vehicle body 1 is adapted to the shape of the mounting member 2.

[0046] In the embodiment of the present application, the number of protrusions 22 arranged on the periphery of the mounting member 2 can be set to one or more, and when the number of protrusions 22 is set to more than one, the multiple protrusions 22 are evenly distributed on the periphery of the mounting member 2, so that the extrusion pressure on the inner periphery of the mounting hole 11 is more uniform, thereby making it less likely for deformation to occur at the mounting hole 11.

[0047] In the mounting structure of the vehicle body provided in the embodiment of the present application, the mounting member 2 is sleeved in the mounting hole 11 of the vehicle body 1, and the vehicle body parts are mounted in the through hole 21 of the mounting member 2, so that the vehicle body parts are mounted on the vehicle body 1 through the mounting member 2, and the outer periphery of the mounting member 2 is interference fit with the mounting hole 11 of the vehicle body 1 at the protrusion 22, so as to improve the stability of the mounting member 2 at the mounting hole 11 of the vehicle body 1, thereby improving the stability of the vehicle body parts at the mounting hole 11 of the vehicle body 1. In addition, since the outer periphery of the mounting member 2 is interference fit with the mounting hole 11 only in the local area where the protrusion 22 is provided, it is possible to reduce the excessive extrusion of the outer periphery of the mounting member 2 on the inner periphery of the mounting hole 11, thereby reducing the deformation of the mounting hole 11 caused by excessive extrusion, so that the mounting hole 11 of the vehicle body 1 is not easily deformed. Therefore, compared with the method of directly installing the body parts in the mounting hole 11 of the body 1 in the related art, the outer periphery of the mounting member 2 of the present application is interference fit with the mounting hole 11 in the local area where the protrusion 22 is provided, so as to improve the stability of the mounting member 2 in the mounting hole 11 of the body 1, thereby improving the stability of the body parts installed at the mounting hole 11 of the body 1, and can also reduce the deformation caused by excessive extrusion of the outer periphery of the mounting member 2 on the inner periphery of the mounting hole 11, so that the mounting hole 11 of the body 1 is not easily deformed. In addition, the body parts are installed in the mounting hole 11 of the body 1 through the mounting member 2, so that the body parts will not directly contact the mounting hole 11 of the body 1, so the force on the body parts will not be directly transmitted to the mounting hole 11 of the body 1, so that the mounting hole 11 of the body 1 is not easily deformed.

[0048] In the embodiment of the present application, since the mounting member 2 and the vehicle body 1 are manufactured separately, the material of the mounting member 2 can be the same as or different from the material of the vehicle body 1, and since the vehicle body parts are arranged in the through hole 21 of the mounting member 2, the mounting member 2 can select a material suitable for the vehicle body parts according to the strength, hardness and other properties required by the vehicle body parts, so that the mounting member 2 with the vehicle body parts installed is not easy to deform, thereby improving the strength of the vehicle body 1 at the mounting hole 11.

[0049] In some possible embodiments of the present application, see Figure 4 and Figure 5 The outer periphery of the mounting member 2 includes a plurality of contour curved surfaces 231 , which are connected end to end in sequence along the circumference of the mounting member 2 , and two adjacent contour curved surfaces 231 are protruded near the connection position to form a protruding portion 22 .

[0050] It should be noted that the arrangement of the protrusion 22 makes the periphery of the mounting member 2 smoother, thereby making the process of the mounting member 2 being inserted into the mounting hole 11 of the vehicle body 1 smoother. In addition, to improve the smoothness of the periphery of the mounting member 2, two adjacent contour surfaces 231 can smoothly transition at the connection position.

[0051] In the embodiment of the present application, the number of contour surfaces 231 included in the outer periphery of the mounting member 2 can be set to two, three, four, etc., which can be specifically set according to actual needs.

[0052] In the embodiment of the present application, each contour surface 231 can completely cover the outer side of the mounting member 2 along the axial direction X of the through hole 21, or can cover a local area of ​​the outer side of the mounting member 2 along the axial direction X of the through hole 21, which can be specifically set according to actual needs.

[0053] In some possible embodiments of the present application, see Figure 4 and Figure 5 The curvature of each contour curved surface 231 and the size of each contour curved surface 231 in the circumferential direction of the mounting member 2 are equal, so that the mounting member 2 is rotationally symmetrical along the central axis of the through hole 21.

[0054] In the embodiment of the present application, the mounting member 2 is rotationally symmetrical along the central axis of the through hole 21, so that when the mounting member 2 is embedded in the mounting hole 11 of the vehicle body 1, the extrusion force on the inner periphery of the mounting hole 11 is more uniform, thereby further preventing deformation from occurring at the mounting hole 11.

[0055] In some possible embodiments of the present application, see Figure 4 and Figure 5 The mounting member 2 includes a rod portion 23 and an end portion 24 , the end portion 24 is arranged at one end of the rod portion 23 along the axial direction X of the mounting hole 11 , and the radial dimension of the rod portion 23 is smaller than the radial dimension of the end portion 24 ; the protrusion 22 is arranged on the outer periphery of the rod portion 23 .

[0056] In the embodiment of the present application, the rod portion 23 and the end portion 24 can be integrally formed, or can be connected by welding, screw connection, etc., which is specifically set according to actual needs.

[0057] In the present application examples, see Figure 2The mounting hole 11 includes a first hole section 111 and a second hole section 112, and the radial dimension of the first hole section 111 is smaller than the radial dimension of the second hole section 112, so that the mounting hole 11 is stepped. The rod portion 23 is arranged in the first hole section 111, and the protrusion 22 on the outer periphery of the rod portion 23 is interference-fitted with the inner periphery of the first hole section 111, so as to firmly mount the mounting member 2 in the mounting hole 11 of the vehicle body 1, and the end portion 24 is arranged in the second hole section 112 and abuts against the stepped position where the second hole section 112 connects to the first hole section 111, so as to axially limit the mounting member 2, thereby improving the reliability of the mounting member 2 in the mounting hole 11.

[0058] Furthermore, the end portion 24 can be completely embedded in the second hole segment 112 so that the end surface of the end portion 24 away from the rod portion 23 is flush with the end surface of the vehicle body 1; the end portion 24 can also be partially embedded in the second hole segment 112 so that the end surface of the end portion 24 away from the rod portion 23 protrudes from the end surface of the vehicle body 1, which can be specifically set according to the size of the second hole segment 112 along the axial direction X of the mounting hole 11 and actual design requirements.

[0059] In addition, the mounting hole 11 can also be set to a cylindrical shape, and the radial dimension of the mounting hole 11 is adapted to the radial dimension of the rod 23, so that only the rod 23 on the mounting member 2 is embedded in the mounting hole 11, and the end 24 is exposed outside the mounting hole 11 and protrudes relative to the end face of the vehicle body 1.

[0060] In some possible embodiments of the present application, see Figure 4 The end surface of the other end of the rod portion 23 away from the end portion 24 smoothly transitions to the outer peripheral surface of the rod portion 23 to form a transition curved surface 232 .

[0061] In the embodiment of the present application, the end face of the other end of the rod 23 away from the end 24 is the starting end face when the mounting member 2 is embedded in the mounting hole 11. Therefore, the smooth transition between the end face of the other end of the rod 23 away from the end 24 and the outer peripheral surface of the rod 23 can reduce the excessive extrusion of the starting end face of the mounting member 2 on the inner periphery of the mounting hole 11, so that deformation is not easily generated at the mounting hole 11 of the vehicle body 1.

[0062] In some possible embodiments of the present application, see Figure 4 , Figure 6 as well as Figure 7 The end portion 24 includes a plurality of side planes 241 , which are connected end to end in sequence along the circumferential direction of the mounting member 2 , and the connection position of two adjacent side planes 241 is smoothly transitioned.

[0063] In the embodiment of the present application, the number of the side planes 241 included in the end portion 24 can be two, three, four, etc., which can be specifically set according to actual needs.

[0064] In the embodiment of the present application, each side plane 241 may completely cover the outer side of the end portion 24 along the axial direction X of the through hole 21, or may cover a partial area of ​​the outer side of the end portion 24 along the axial direction X of the through hole 21, which may be specifically set according to actual needs. When each side plane 241 completely covers the outer side of the end portion 24 along the axial direction X of the through hole 21, the end portion 24 is prismatic.

[0065] In the present application examples, see Figure 2 and Figure 7 At least a portion of the outer circumference of the end portion 24 cooperates with the inner circumference of the second hole section 112 of the mounting hole 11, so the multiple side planes 241 constituting the outer circumference of the end portion 24 transition smoothly at adjacent connection positions, making the outer circumference of the end portion 24 relatively smooth, thereby making the process of the end portion 24 being embedded in the second hole section 112 of the mounting hole 11 smoother.

[0066] In some possible embodiments of the present application, see Figure 8 A first angle α is formed between the axial direction X of the through hole 21 and the radial direction of the end portion 24 , and the first angle α is set between 0°-180°.

[0067] In the embodiment of the present application, by adjusting the angle of the first angle α, the end 24 and the rod 23 can form different inclination angles to meet the installation requirements of vehicle body parts with different inclination angles, and since the mounting member 2 and the vehicle body 1 are manufactured separately, the angle of the first angle α can be adjusted without changing the inclination angle of the mounting hole 11 of the vehicle body 1. The vehicle body parts with different inclination angles can be installed on the vehicle body 1 with the same mounting hole 11 through the mounting member 2 with different first angles α, thereby facilitating the production and manufacturing of the vehicle body 1.

[0068] In the embodiment of the present application, the first angle α can be set to 60 degrees, 90 degrees, 120 degrees, etc., which can be set according to the inclination angle of the vehicle body parts to be installed. Figure 8 , Figure 8 There are three central axes, namely the first central axis a, the second central axis b, and the third central axis c, and three radial lines, namely the first radial line d, the second radial line e, and the third radial line f. When the axial direction X of the through hole 21 is parallel to the second central axis b, and the radial direction of the end 24 is parallel to the second radial line e, it is Figure 8 In the state shown by the middle rod portion 23 and the end portion 24, at this time, the first angle α is 90 degrees; when the axial direction X of the through hole 21 is parallel to the first central axis a, and the radial direction of the end portion 24 is parallel to the first radial straight line d or the second radial straight line e, the first angle α is less than 90 degrees; when the axial direction X of the through hole 21 is parallel to the third central axis c, and the radial direction of the end portion 24 is parallel to the second radial straight line e or the third radial straight line f, the first angle α is greater than 90 degrees.

[0069] In some possible embodiments of the present application, see Figure 1 and Figure 2 The vehicle body 1 is made of a first material, the mounting member 2 is made of a second material, and the hardness of the second material is greater than that of the first material.

[0070] It should be noted that this arrangement makes it difficult for the mounting member 2 on which the vehicle body parts are mounted to deform, thereby further making it difficult for the mounting hole 11 of the vehicle body 1 to deform, thereby improving the strength of the vehicle body 1 at the mounting hole 11 .

[0071] In some possible embodiments of the present application, the first material is an aluminum alloy material, and the second material is an iron alloy material.

[0072] It should be noted that the first material is aluminum alloy, which has the advantage of being light in weight, so as to meet the lightweight requirements of the vehicle body 1 . The second material is iron alloy, which has the advantages of being high in strength and easy to produce and process, so as to improve the strength of the vehicle body 1 at the mounting hole 11 , while also facilitating the production of the mounting part 2 .

[0073] The present application also provides a vehicle, see Figure 1 , Figure 2 , Figure 3 as well as Figure 4 , including any one of the above-mentioned vehicle body mounting structures.

[0074] In the embodiment of the present application, the vehicle may be a car, a bicycle, a motorcycle, etc., and the specific setting may be based on actual needs.

[0075] The vehicle provided in the embodiment of the present application includes the mounting structure of the vehicle body provided in the first aspect, and thus can achieve the same effect, that is, the vehicle body parts are mounted on the vehicle body 1 through the mounting member 2, and the outer periphery of the mounting member 2 is interference-fitted with the mounting hole 11 in the local area where the protrusion 22 is provided, so as to improve the stability of the mounting member 2 in the mounting hole 11 of the vehicle body 1, thereby improving the stability of the vehicle body parts in the mounting hole 11 of the vehicle body 1, and can also reduce the deformation caused by excessive extrusion of the outer periphery of the mounting member 2 on the inner periphery of the mounting hole 11, so that the mounting hole 11 of the vehicle body 1 is not easily deformed. In addition, the vehicle body parts are mounted in the mounting hole 11 of the vehicle body 1 through the mounting member 2, so that the vehicle body parts will not directly contact the mounting hole 11 of the vehicle body 1, so the force on the vehicle body parts will not be directly transmitted to the mounting hole 11 of the vehicle body 1, so that the mounting hole 11 of the vehicle body 1 is not easily deformed.

[0076] The above are only preferred embodiments of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
