Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of vehicles, and particularly relates to a sectional general-purpose light truck front bumper assembly. BACKGROUND

[0002] The light truck front bumper assembly is located below the cab, and comprises a front bumper plastic body and a front bumper metal framework. The front bumper metal framework provides support for the front bumper plastic body and serves as a connection with the vehicle frame.

[0003] At present, the front bumper metal framework of the light truck is developed in different widths according to the different widths of the cab. In the case of different width vehicles on the same platform, the product cannot be universalized and serialized, and the one-time investment cost of product development increases.

[0004] Therefore, the prior art still has some defects. CONTENT OF THE UTILITY MODEL

[0005] The application provides a sectional general-purpose light truck front bumper assembly to solve at least one of the above technical problems.

[0006] The technical scheme adopted by the application is as follows:

[0007] The application provides a sectional general-purpose light truck front bumper assembly, which comprises a front bumper framework, an outer cover and a connecting bracket. The outer cover and the connecting bracket are arranged on the two sides of the front bumper framework, and the front bumper framework is connected with the vehicle frame through the connecting bracket. The front bumper framework comprises a left side framework, a right side framework and a middle framework. The left side framework and the right side framework are symmetrically arranged at the two ends of the middle framework and are fixedly connected with the middle framework. The connecting bracket comprises a first connecting part connected with the middle framework and a second connecting part connected with the vehicle frame. The first connecting part and the second connecting part have a buffer cavity therebetween.

[0008] In the above scheme, by adopting the sectional framework structure, the light truck with different cab widths can be effectively adapted by only changing the size of the middle framework. Compared with the sectional framework in the prior art which leaves a gap between the sections, the front bumper framework in the application is still a whole framework, which can effectively adapt to the use requirements of light trucks with different cab widths and still ensure that the vehicle has sufficient anti-collision ability. In addition, compared with the traditional way of directly connecting the light truck front bumper framework with the vehicle frame, the connection bracket is arranged in the application, and the buffer cavity is arranged in the connection bracket, which improves the energy absorption effect of the front bumper framework and is beneficial to further improving the anti-collision ability.

[0009] As a preferred embodiment of the present application, the middle frame body comprises an upper side, a middle part and a lower side connected in sequence in the vertical direction, and the upper side and the lower side are convex relative to the middle part in the direction away from the frame.

[0010] With the above structure, when the vehicle is in collision, the upper side and the lower side will generally first receive the impact and collapse backward, and then the middle part of the middle frame body will receive the impact, that is, by using the above scheme, the energy absorption effect of the middle frame body when impacted can be improved to a certain extent, and the anti-collision ability is improved.

[0011] Preferably, the upper side, the lower side and the middle part have a transition section therebetween.

[0012] As a preferred embodiment of the present application, the left frame and the right frame are provided with a first welding portion at one end thereof facing the middle frame body, and the middle frame body is provided with a second welding portion corresponding to the first welding portion at both ends thereof, and the left frame and the right frame are fixedly connected with the middle frame body through welding cooperation between the first welding portion and the second welding portion.

[0013] In the above scheme, the connection strength between the left frame, the middle frame and the right frame is higher by using the welding connection mode than the detachable connection mode such as bolt connection, and the connection structure is more stable, which is conducive to improving the structural strength and anti-collision ability of the entire front frame.

[0014] As a preferred embodiment of the present application, the first connecting portion is provided with a plurality of first connecting holes, both ends of the middle frame body are respectively provided with a plurality of second connecting holes corresponding to the first connecting holes, and the connecting bracket is further provided with a fastening bolt, and the fastening bolt passes through the first connecting hole and the second connecting hole to lock and fix the connecting bracket on the middle frame.

[0015] As a preferred embodiment of the present application, the second connecting portion is provided with a plurality of hollow portions.

[0016] In the above scheme, by providing the hollow portion, on the one hand, the connection operation between the connecting bracket and the frame can be facilitated, and on the other hand, the installation of vehicle accessories such as lamps and radars can be facilitated, and in addition, by providing the hollow portion, the weight of the connecting bracket and even the entire front frame can be reduced.

[0017] As a preferred embodiment of the present application, the upper side, the lower side, the left side frame and the right side frame are provided with a plurality of docking holes, and the outer cover is provided with a plurality of connecting seats corresponding to the docking holes on the side of the front frame.

[0018] In the above scheme, the installation of the outer cover is facilitated by the cooperation between the docking holes and the connecting seats, and at the same time, the positioning of the connecting seats and the connecting holes is facilitated by the protrusion of the connecting seats, so as to facilitate the fastening connection by bolts, and at the same time, the protrusion of the connecting seats cooperates with the protrusion of the upper side and the lower side in the above scheme, so as to create a buffer space between the main body of the outer cover and the middle body of the middle frame, further improving the energy absorption and anti-collision ability of the entire front bumper assembly.

[0019] As a preferred embodiment of the present application, the outer cover is a plastic outer cover, which adopts an integral structure or a segmented structure.

[0020] In the above scheme, the use of an integral structure is beneficial to improve the overall structural strength of the outer cover to improve the anti-collision ability of the front bumper assembly, but this will increase the difficulty and support cost of the mold manufacturing of the outer cover; the use of a segmented structure can greatly reduce the production difficulty and production cost of the outer cover, and preferably, the outer cover can be segmented in the same segmented manner as the front frame, and since the left side frame and the right side frame are general components, the mold of the middle structure of the outer cover can be changed to produce the outer cover of the light truck suitable for different cab widths, greatly saving the production cost.

[0021] As a preferred embodiment of the present application, the first connecting part is provided with a buffer layer on the side facing the middle frame, and the second connecting part is provided with a buffer layer on the side facing the frame.

[0022] In the above scheme, the buffer layer can reduce the vibration of the connection structure between the connecting bracket and the front frame and the frame caused by the bumping of the vehicle, ensure the stability of the connection structure between the connecting bracket and the front frame and the frame, and provide certain energy absorption and buffering effect when the vehicle collides.

[0023] As a preferred embodiment of the present application, the buffer cavity is filled with a buffer material.

[0024] In the above scheme, the filling of the buffer material in the buffer cavity can further improve the energy absorption and shock absorption effect of the buffer cavity.

[0025] In summary, by adopting the above scheme, the generalization and serialization of the front bumper assembly product can be realized, the product research and development cost is reduced, and the energy absorption and buffering capacity of the front bumper framework is improved, which is beneficial to ensure the safety of the vehicle.

However, the present application can be practiced without the specific details. In other instances, well-known methods, procedures, components, and circuits have not been described in detail so as not to obscure the present application. Some embodiments of the present application can relate to the examples provided in the specification, but the present application is not limited to these examples. It will be apparent to those skilled in the art that certain embodiments of the application can be practiced without several of the features which are next described in connection with the figures.

[0041] In the present application, unless specifically defined and limited otherwise, the terms "mount", "connect", "connection", "fixed", and the like should be broadly understood, for example, can be fixed connection, can also be detachable connection, or integrated; can be mechanical connection, can also be electrical connection, and can also be communication; can be directly connected, can also be indirectly connected through an intermediate medium, can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0042] In the present application, unless specifically defined and limited otherwise, the first feature is "on" or "under" the second feature, which can be direct contact between the first and second features, or indirect contact between the first and second features through an intermediate medium. In the description of the specification, the description referring to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0043] At present, the light truck front bumper metal skeleton is developed in different width categories according to the different widths of the cab. In the case of different width whole vehicle configurations in the same platform, the product generalization and serialization cannot be realized, and the one-time investment cost of product development increases. In the prior art, the front bumper skeleton 1 is segmented to improve the product generalization under the premise of adapting to different width cabs, but the existing segmented skeleton structure has the risk of reduced structural strength due to the gap between the segments.

[0044] To solve the above problems at the same time, referring to Figures 1-7 As shown in the figure, the application provides a segmented universal light truck front bumper assembly, which comprises a front bumper framework 1, an outer cover 3 and a connecting bracket 2. The outer cover 3 and the connecting bracket 2 are arranged on both sides of the front bumper framework 1. The front bumper framework 1 is connected with the frame through the connecting bracket 2. The front bumper framework 1 comprises a left side framework 12, a right side framework 13 and a middle framework 11. The left side framework 12 and the right side framework 13 are symmetrically arranged at both ends of the middle framework 11 and are fixedly connected with the middle framework 11. The connecting bracket 2 comprises a first connecting part 21 connected with the middle framework 11 and a second connecting part 22 connected with the frame. There is a buffer cavity 23 between the first connecting part 21 and the second connecting part 22.

[0045] As a preferred embodiment of the application, the left side framework 12, the right side framework 13 and the middle framework 11 are connected by welding. The left side framework 12 and the right side framework 13 are provided with first welding parts at one end facing the middle framework 11. The two ends of the middle framework 11 are provided with second welding parts corresponding to the first welding parts. The left side framework 12 and the right side framework 13 are fixedly connected with the middle framework 11 through the welding between the first welding parts and the second welding parts. Compared with the detachable connection mode such as bolt connection, the welding connection mode can make the connection strength between the left side framework 12, the middle framework and the right side framework 13 higher and the connection structure more stable, which is conducive to improving the structural strength and the crashworthiness of the whole front bumper framework 1. In the above scheme, through the cooperation between the first welding parts and the second welding parts with appropriate shapes, the welding area can be expanded, and the connection strength can be further improved.

[0046] By adopting the segmented framework structure, the light truck with different cab widths can be effectively adapted by changing the size of the middle framework 11. Compared with the segmented framework in the prior art which leaves a gap between the segments, the front bumper framework 1 in the application is still a whole framework, which can effectively adapt to the use requirements of light trucks with different cab widths while still providing sufficient crashworthiness for the vehicle. In addition, compared with the traditional way of directly connecting the light truck front bumper framework 1 with the frame, the application improves the energy absorption effect of the front bumper framework 1 by setting the connecting bracket 2 and the buffer cavity 23 inside the connecting bracket 2, which is conducive to further improving the crashworthiness.

[0047] As a preferred embodiment of the present application, the outer cover 3 is a plastic outer cover 3, which adopts an integral structure or a segmented structure. On the one hand, the existing engineering plastics have the advantages of light weight and high strength, and on the other hand, the segmented structure of the outer cover 3 can greatly reduce the production difficulty and production cost of the outer cover 3. Preferably, the outer cover 3 can be segmented in the same segmented manner as the front bumper framework 1. Since the left side framework 12 and the right side framework 13 are general components, the outer cover 3 for light trucks with different cab widths can be produced by only changing the mold of the middle structure of the outer cover 3, which greatly saves production costs. Of course, the outer cover 3 can still adopt an integral structure to improve the overall structural strength of the outer cover 3 and the anti-collision ability of the front bumper assembly. The present application does not make specific limitations on this.

[0048] It should be noted here that the segmentation manner of the segmented outer cover 3 is not limited to the above example. The above example is only a preferred example of the present application, and different segmentation manners can be selected according to actual production and processing needs. The present application does not make specific limitations on this.

[0049] In one example, continuing to refer to Figure 2 、 Figure 4 , the middle framework 11 includes an upper side 112, a middle body 111 and a lower side 113 connected in sequence in the vertical direction. The upper side 112 and the lower side 113 are convex relative to the middle body 111 in the direction away from the frame. Preferably, the upper side 112, the lower side 113 and the middle body 111 have a transition section 114 therebetween. With the above structure, when the vehicle collides, the upper side 112 and the lower side 113 will first receive the impact and collapse backward, and then the middle body 111 of the middle framework 11 will receive the impact. That is, by using the above scheme, the energy absorption effect of the middle framework 11 when impacted can be improved to a certain extent, and the anti-collision ability is improved. The setting of the transition section 114 can enlarge the contact area and welding area between the middle framework 11 and the left side framework 12 and the right side framework 13 during subsequent welding connection, thereby improving the connection strength and further improving the structural strength and anti-collision ability of the entire front bumper framework 1.

[0050] Continuing to refer to Figure 3As shown, the first connecting part 21 is provided with a plurality of first connecting holes 211, and the two ends of the middle body 111 are respectively provided with a plurality of second connecting holes 221 corresponding to the first connecting holes 211. The connecting bracket 2 is further provided with fastening bolts, which pass through the first connecting holes 211 and the second connecting holes 221 to lock and fix the connecting bracket 2 on the middle frame 11. In this way, the connecting bracket 2 can be conveniently connected with middle frames 11 of different sizes, improving the versatility of the connecting bracket 2. In addition, the above connecting structure facilitates the disassembly and assembly of the front frame 1 and the connecting bracket 2, and facilitates the maintenance and replacement of the front frame.

[0051] As a preferred embodiment of the present application, referring to Figure 3 As shown, the second connecting part 22 is provided with a plurality of hollow parts 24. The hollow parts 24 can facilitate the connection between the connecting bracket 2 and the vehicle frame, and also facilitate the installation of vehicle accessories such as lamps and radars. In addition, the hollow parts 24 can also reduce the weight of the connecting bracket 2 and the entire front frame 1.

[0052] Further, referring to Figure 2 , Figure 4 and Figure 5 As shown, the upper side 112, the lower side 113, the left side frame 12 and the right side frame 13 are provided with a plurality of butt joints 115, and the side of the outer cover 3 facing the front frame 1 is provided with a plurality of connecting seats 31 corresponding to the butt joints 115. The connecting seats 31 protrude towards the front frame 1. The butt joints 115 and the connecting seats 31 facilitate the installation of the outer cover 3. In addition, the protrusion of the connecting seats 31 facilitates the positioning of the connecting holes by the installer, so as to be fastened and connected by bolts. In addition, the protrusion of the connecting seats 31 in combination with the protrusion of the upper side 112 and the lower side 113 in the above-mentioned scheme can also create a buffer space between the main body of the outer cover 3 and the middle body 111 of the middle frame 11, further improving the energy absorption and anti-collision capability of the entire front bumper assembly.

[0053] It should be noted that the connection structure between the outer cover 3 and the front frame 1 is not limited to the above-mentioned example. The above-mentioned example is only a preferred example of the present application, which can be connected by setting protruding connecting seats 31 on the side of the front frame 1 facing the outer cover 3 and setting butt joints 115 on the outer cover 3, or can also use other more different connection structures or connection methods such as buckle connection which are more convenient for disassembly and replacement, so as to facilitate the replacement of the outer cover 3. The present application does not make specific limitations in this regard.

[0054] Further, as a preferred embodiment of the present application, the first connecting part 21 is provided with a buffer layer on the side facing the middle frame 11, and the second connecting part 22 is provided with a buffer layer on the side facing the vehicle frame, and the buffer cavity 23 is filled with a buffer material. By providing the buffer layer, on the one hand, the vibration of the vehicle bumping can be reduced to the connecting structure between the connecting bracket 2, the front frame 1 and the vehicle frame, the stability of the connecting structure between the connecting bracket 2, the front frame 1 and the vehicle frame can be ensured, and on the other hand, the buffer layer can provide a certain energy absorption and buffering effect when the vehicle collides, and by filling the buffer material in the buffer cavity 23, the energy absorption and shock absorption effect of the buffer cavity 23 can be further improved. Preferably, the buffer layer is made of rubber material, and the buffer cavity 23 is filled with rubber material with a mesh structure or other elastic energy-absorbing material, which can improve the buffering performance while ensuring the effect of air guiding and ventilation cooling. Of course, the material and shape of the buffer layer, the selection of the buffer material and the filling method of the buffer material are not limited in the present application.
