Description

Technical Field

[0001] This application relates to the field of vehicle bodies, and in particular to a front-end structure of a vehicle body and a vehicle. Background Technology

[0002] In vehicles, a radiator is usually installed at the front of the vehicle body, and the top of the radiator is usually mounted on the radiator crossbeam located at the front of the vehicle body.

[0003] In traditional vehicle body structures, the radiator upper crossbeam is usually directly connected to the upper beam of the engine compartment by welding or bolting. Since there is no positioning structure between the radiator upper crossbeam and the upper beam of the engine compartment, it is difficult to guarantee the positional accuracy after the two are connected. This is not conducive to ensuring the matching of positions between the front-end components of the vehicle body, and is not conducive to improving the overall quality of the vehicle body. Utility Model Content

[0004] In view of this, this application aims to propose a front-end structure for a vehicle body to help ensure the positional compatibility between front-end components of the vehicle body, thereby improving the overall quality of the vehicle body.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows:

[0006] A front-end structure of a vehicle body includes an upper side beam of the engine compartment and an upper crossbeam of a radiator connected to the upper side beam of the engine compartment by a connector;

[0007] The upper side beam of the cabin is provided with a positioning bracket, and the end of the upper crossbeam of the radiator is positioned on the upper side beam of the cabin through the positioning bracket;

[0008] The connector includes a first connector that fixes the upper crossbeam of the radiator, the positioning bracket, and the upper side beam of the cabin together.

[0009] Furthermore, the positioning bracket is located at the top of the upper side beam of the cabin, and the upper crossbeam of the radiator is connected to the top of the upper side beam of the cabin;

[0010] The first connector secures the radiator upper crossbeam, the positioning bracket, and the engine compartment upper side beam together along the vertical direction of the vehicle.

[0011] Furthermore, the positioning bracket includes a fixing plate and a positioning post disposed on the fixing plate;

[0012] The fixing plate is fixed to the upper side beam of the engine compartment, the positioning post is arranged along the vertical direction of the whole vehicle, and the upper crossbeam of the radiator is provided with positioning holes for the positioning post to be inserted.

[0013] The first connector secures the upper beam of the radiator, the fixing plate, and the upper side beam of the cabin together.

[0014] Furthermore, the fixing plate is fixed to the upper side beam of the cabin by multiple fixing bolts;

[0015] At least some of the fixing bolts are located between the upper crossbeam of the radiator and the fixing plate, and the upper crossbeam of the radiator is provided with clearance holes to avoid the portion of the fixing bolts.

[0016] Furthermore, the positioning bracket is arranged near the front end of the upper side beam of the cabin;

[0017] The front end of the upper beam of the engine compartment is provided with a connecting bracket. The connecting component includes a second connecting component that fixes the upper beam of the radiator and the connecting bracket together along the vertical direction of the whole vehicle.

[0018] Furthermore, the first connecting member is a plurality of members arranged at intervals along the length direction of the crossbeam on the radiator;

[0019] The first connector and the second connector are arranged in a staggered manner relative to the center line of the upper crossbeam of the radiator;

[0020] The centerline of the upper crossbeam of the radiator is the centerline of the upper crossbeam of the radiator in the front-rear direction of the vehicle.

[0021] Furthermore, both the first and second connectors use connecting bolts.

[0022] Furthermore, the upper crossbeam of the radiator is a tubular beam, and the upper crossbeam of the radiator is provided with connecting sleeves arranged respectively corresponding to each of the connecting parts;

[0023] Each of the aforementioned connectors is inserted into its corresponding connecting sleeve.

[0024] Furthermore, the upper crossbeam of the radiator is made of hot gas expansion tubes.

[0025] Compared with related technologies, this application has the following advantages:

[0026] (1) The front-end structure of the vehicle body described in this application, by setting a positioning bracket on the upper side beam of the engine compartment, allows the end of the upper crossbeam of the radiator to be positioned on the upper side beam of the engine compartment through the positioning bracket. At the same time, the upper crossbeam of the radiator, the positioning bracket and the upper side beam of the engine compartment are fixed together through the first connecting member. Thus, while the upper crossbeam of the radiator is connected to the upper side beam of the engine compartment through the connecting member, the positioning function of the positioning bracket can also be used to ensure the relative positional accuracy between the radiator crossbeam and the upper side beam of the engine compartment. This helps to ensure the positional matching between the front-end components of the vehicle body, thereby improving the overall quality of the vehicle body.

[0027] (2) The positioning bracket is located at the top of the upper side beam of the engine compartment, and the upper crossbeam of the radiator is connected to the top of the upper side beam of the engine compartment. At the same time, the first connecting piece is connected along the vertical direction of the whole vehicle, which facilitates the connection operation of the upper crossbeam of the radiator on the upper side beam of the engine compartment.

[0028] (3) The positioning bracket is composed of a fixed plate and a positioning column on the fixed plate. The structure is simple, easy to design and manufacture, and also facilitates the arrangement of the positioning bracket on the upper beam of the cabin.

[0029] (4) The fixing plate is fixed to the upper beam of the nacelle by fixing bolts. The structure is simple, the operation is convenient, and it is easy to replace the transfer positioning bracket. At the same time, when the fixing bolt is located between the upper beam of the radiator and the fixing plate, the upper beam of the radiator is provided with a clearance hole to avoid the fixing bolt. This can also avoid the large gap between the upper beam of the radiator and the upper beam of the nacelle caused by the fixing bolt. It can realize the fit design between the upper beam of the radiator and the upper beam of the nacelle, which helps to improve the support stiffness of the upper beam of the nacelle to the upper beam of the radiator and improve the stability of the connection arrangement of the upper beam of the radiator on the upper beam of the nacelle.

[0030] (5) By setting a connecting bracket at the front end of the upper side beam of the engine compartment and fixing the upper crossbeam of the radiator and the connecting bracket together through the second connector, the reliability of the connection arrangement of the upper crossbeam of the radiator on the upper side beam of the engine compartment can be increased, which helps to improve the stability of the radiator arrangement at the front end of the vehicle body.

[0031] (6) The first connecting member is arranged in multiple spaced intervals, and each connecting member is arranged in a staggered manner relative to the center line of the upper beam of the radiator. This can improve the deformation resistance of the end position where the upper beam of the radiator connects to the upper side beam of the engine compartment. It can effectively prevent deformation at the connection position between the upper beam of the radiator and the upper side beam of the engine compartment during vehicle collision, reduce the deformation trend, and improve the structural stability of the upper beam of the radiator.

[0032] (7) Each connecting part adopts connecting bolts, which is simple in structure, easy to operate, and low in cost. It can also realize the detachable design of the crossbeam on the radiator, which can facilitate the later maintenance and repair work.

[0033] (8) A connecting sleeve is installed inside the upper beam of the radiator so that each connecting part is inserted in the corresponding connecting sleeve. This can increase the structural strength of the connection position between the upper beam of the radiator and the upper side beam of the engine room, improve the overall rigidity of the connection point between the upper beam of the radiator and the upper side beam of the engine room, and help improve the stability of the connection between the upper beam of the radiator and the upper side beam of the engine room.

[0034] (9) The upper beam of the radiator adopts hot gas expansion tube, which is conducive to the cross-sectional design and forming of the upper beam of the radiator, and also helps to ensure the structural performance of the upper beam of the radiator.

[0035] This application also proposes a vehicle having a front body structure as described above.

[0036] By setting the front-end structure of the vehicle body as described above, the relative positional accuracy between the upper crossbeam of the radiator and the upper side beam of the engine compartment can be guaranteed, which helps to ensure the positional matching between the front-end components of the vehicle body and is conducive to improving the overall quality of the vehicle body.

Those skilled in the art can understand the specific meaning of the above terms in this application in light of the specific circumstances.

[0059] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0060] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0061] An embodiment of the first aspect of this application provides a vehicle front end structure, which mainly relates to the connection arrangement of the radiator top crossbeam for mounting on the top of the radiator on the upper side beam of the engine compartment. Through its innovative structural design, the vehicle front end structure of this embodiment can ensure the relative positional accuracy between the radiator crossbeam and the upper side beam of the engine compartment, thereby helping to ensure the positional matching between the vehicle front end components.

[0062] In related technologies, in order to dissipate heat from the cooling medium used for cooling equipment such as the powertrain, a radiator is usually installed in the vehicle. The radiator is generally located at the front of the vehicle body, and the top of the radiator is usually mounted on the radiator crossbeam located at the front of the vehicle body.

[0063] In traditional vehicle body structures, the two ends of the radiator upper crossbeam are generally connected to the upper side beams of the engine compartment on the left and right sides. When connecting, the ends of the radiator upper crossbeam are usually overlapped to the upper side beams of the engine compartment, and then the radiator upper crossbeam is directly connected to the upper side beams of the engine compartment by welding or bolting.

[0064] At this point, the traditional connection method lacks a corresponding positioning structure between the radiator upper crossbeam and the engine compartment upper side beam, making it difficult to guarantee the positional accuracy of the radiator upper crossbeam after it is connected to the engine compartment upper side beam. This results in positional deviations in the radiator upper crossbeam and even the radiator itself, which is not conducive to ensuring the matching of positions between the front-end components of the vehicle body, and thus is not conducive to improving the overall quality of the vehicle body.

[0065] In view of this, in order to overcome the shortcomings of the related technologies, the front end structure of the vehicle body in this embodiment combines... Figures 1 to 9 As shown, the overall design includes a cabin upper beam 1 and a radiator upper crossbeam 2 connected to the cabin upper beam 1 by a connector 3.

[0066] The upper beam 1 of the cabin is provided with a positioning bracket 4, the end of the upper beam 2 of the radiator is positioned on the upper beam 1 of the cabin through the positioning bracket 4, and the connecting piece 3 also includes a first connecting piece 31 that fixes the upper beam 2 of the radiator, the positioning bracket 4 and the upper beam 1 of the cabin together.

[0067] Therefore, by setting a positioning bracket 4 on the upper side beam 1 of the engine compartment, the end of the upper crossbeam 2 of the radiator is positioned on the upper side beam 1 of the engine compartment through the positioning bracket 3. At the same time, the upper crossbeam 2 of the radiator, the positioning bracket 4 and the upper side beam 1 of the engine compartment are fixed together through the first connecting member 31. In this embodiment, while the upper crossbeam 2 of the radiator is connected to the upper side beam 1 of the engine compartment through the connecting member 3, the positioning function of the positioning bracket 4 can also be used to ensure the relative positional accuracy between the radiator crossbeam 2 and the upper side beam 1 of the engine compartment. This helps to ensure the positional matching between the front-end components of the vehicle body and can achieve the effect of improving the overall quality of the vehicle body.

[0068] Based on the above overview, specifically, it should be noted that, please refer to [the above text]. Figure 1 As shown, at the front of the vehicle body, the radiator upper crossbeam 2 is usually connected between the upper side beams 1 of the engine compartment on the left and right sides, and the connection method between the radiator upper crossbeam 2 and the upper side beams 1 of each side engine compartment is generally the same. Therefore, this embodiment will also take the connection method between the radiator upper crossbeam 2 and the upper side beam 1 of one side engine compartment as an example for explanation.

[0069] Furthermore, in a vehicle, the radiator upper crossbeam 2 is primarily used for mounting and securing the radiator located at the front of the vehicle body. In practice, a bracket structure for mounting the top of the radiator is typically installed on the radiator upper crossbeam 2, allowing the top of the radiator to be fixed to the vehicle body via bolts. However, it is worth noting that, besides mounting and securing the top of the radiator, the radiator upper crossbeam 2 can also provide a mounting base for other vehicle components (such as headlights) also located at the front of the vehicle body, enabling their mounting and securing within the vehicle body.

[0070] In this embodiment, we continue to combine Figures 1 to 3 As shown, in some of the exemplary embodiments, preferably, the positioning bracket 4 can be located on the top of the upper side beam 1 of the engine compartment. Based on this, the upper crossbeam 2 of the radiator is also connected to the top of the upper side beam 1 of the engine compartment. At the same time, the first connecting member 31 fixes the upper crossbeam 2 of the radiator, the positioning bracket 4 and the upper side beam 1 of the engine compartment together along the vertical direction of the whole vehicle.

[0071] At this time, by positioning the positioning bracket 4 on the top of the upper side beam 1 of the engine compartment, connecting the upper crossbeam 2 of the radiator to the top of the upper side beam 1 of the engine compartment, and connecting the first connecting piece 31 along the vertical direction of the whole vehicle, it is obvious that when setting the positioning bracket 4 on the upper side beam 1 of the engine compartment and connecting the upper crossbeam 2 of the radiator to the upper side beam 1 of the engine compartment, it is convenient to set the positioning bracket 4 on the upper side beam 1 of the engine compartment and to connect the upper crossbeam 2 of the radiator to the upper side beam 1 of the engine compartment.

[0072] It is worth noting that, in addition to positioning the bracket 4 at the top of the upper side beam 1 of the engine compartment, connecting the radiator upper crossbeam 2 to the top of the upper side beam 1 of the engine compartment, and connecting the first connecting member 31 along the vertical direction of the vehicle, in other embodiments, the positioning bracket 4 can also be positioned at other locations on the upper side beam 1 of the engine compartment, and the connection position of the radiator upper crossbeam 2 on the upper side beam 1 of the engine compartment can be adjusted accordingly. Specifically, for example, the positioning bracket 4 can be located on one side of the upper side beam 1 of the engine compartment (such as the side of the front end of the upper side beam 1 facing outwards), and the radiator upper crossbeam 2 can also be connected to one side of the upper side beam 1 of the engine compartment.

[0073] Still by Figure 3 and continue as Figure 4 , Figure 5 and Figure 9 As shown in this embodiment, in some exemplary implementations, the positioning bracket 4 may include, for example, a fixing plate 41 and a positioning post 42 disposed on the fixing plate 41.

[0074] The fixing plate 41 is fixed to the upper side beam 1 of the engine compartment, the positioning post 42 is arranged along the vertical direction of the whole vehicle, the positioning hole 201 for the positioning post 42 to be inserted is provided on the upper cross beam 2 of the radiator, and the first connecting member 31 also specifically connects the upper cross beam 2 of the radiator, the fixing plate 41 and the upper side beam 1 of the engine compartment together.

[0075] Thus, by using a fixed plate 41 and a positioning column 42 on the fixed plate 41 to form the positioning bracket 4, it has the characteristics of simple structure and easy design and manufacturing. At the same time, it can obviously facilitate the arrangement of the positioning bracket 4 on the upper side beam 1 of the cabin.

[0076] Based on the positioning bracket 4 using a fixing plate 41 and a positioning post 42 located on the fixing plate 41, the following continues... Figures 2 to 6 and still combined Figure 9As shown, in some exemplary embodiments of this embodiment, the aforementioned fixing plate 41 can be fixed to the upper side beam 1 of the cabin by a plurality of fixing bolts 5, wherein at least some of the fixing bolts 5 are located between the upper crossbeam 2 of the radiator and the fixing plate 41, and corresponding to the portion of fixing bolts 5 located between the upper crossbeam 2 of the radiator and the fixing plate 41, a clearance hole 202 for avoiding the portion of fixing bolts 5 is also provided on the upper crossbeam 2 of the radiator.

[0077] At this point, it is understandable that fixing plate 41 to the upper side beam 1 of the cabin by fixing bolts 5 has the characteristics of simple structure and easy operation, and also facilitates the replacement of the adapter positioning bracket 4.

[0078] Meanwhile, when some of the fixing bolts 5 are located between the upper crossbeam 2 of the radiator and the fixing plate 41, by providing avoidance holes 202 on the upper crossbeam 2 of the radiator to avoid the fixing bolts 5, this embodiment can obviously also avoid a large gap between the upper crossbeam 2 of the radiator and the upper side beam 1 of the nacelle caused by the fixing bolts 5 (e.g., the protruding head of the fixing bolts 5). This can achieve a close fit design between the upper crossbeam 2 of the radiator and the upper side beam 1 of the nacelle, which helps to improve the support rigidity of the upper side beam 1 of the nacelle to the upper crossbeam 2 of the radiator, and can improve the stability of the connection arrangement of the upper crossbeam 2 of the radiator on the upper side beam 1 of the nacelle.

[0079] In specific implementation, it is worth noting that the following should still be referred to: Figures 4 to 6 To fix the fixing plate 41 in the positioning bracket 4 to the upper beam 1 of the nacelle, a fixing hole 102 can be formed on the upper beam 1 of the nacelle, for example. The fixing hole 102 is a threaded hole. After the fixing bolt 5 passes through the fixing plate 41, it is screwed into the fixing hole 102. Alternatively, as an example, the fixing bolt 5 used for fixing the fixing plate 41 can be two bolts arranged near both ends of the fixing plate 41, and one of the fixing bolts 5 can be located between the upper beam 2 of the radiator and the fixing plate 41. Corresponding to the fixing bolt 5, an avoidance hole 202 is provided on the upper beam 2 of the radiator.

[0080] Furthermore, in specific implementation, to facilitate the installation and fixation of the fixing plate 41 on the upper side beam 1 of the nacelle, preferably, for example, a positioning operation hole 402 can be provided on the fixing plate 41, and correspondingly, a positioning mating hole 104 can be provided on the upper side beam 1 of the nacelle. When installing the fixing plate 41 on the upper side beam 1 of the nacelle, a positioning tool that passes through both the positioning operation hole 402 and the corresponding positioning mating hole 104 can be used to pre-position the fixing plate 41 on the upper side beam 1 of the nacelle, thereby achieving the effect of facilitating the installation and operation of the fixing plate 41.

[0081] In this embodiment, please refer to Figures 4 to 6As shown, in addition to the fixing hole 102 for installing the positioning bracket 4, a threaded connection hole 101 is also provided on the upper side beam 1 of the nacelle. At the same time, a connection through hole 401 is provided on the fixing plate 41. When the first connecting member 31 is connected, it passes through the connection through hole 401 on the upper crossbeam 2 of the radiator and the fixing plate 41, and is screwed into the threaded connection hole 101 on the upper side beam 1 of the nacelle.

[0082] Still Figure 5 and Figure 6 As shown in this embodiment, it is worth noting that the positioning post 42 can be a separate structure from the fixing plate 41, and the positioning post 42 can be fixed to the fixing plate 41 by means of screwing, interference fit, welding or riveting.

[0083] Meanwhile, to facilitate the installation of the positioning post 42 on the fixing plate 41, the positioning post 42 may have a "head" located on one side of the fixing plate 41, for example, like a bolt. Corresponding to the "head" on the positioning post 42, a hollow hole 103 may also be provided on the upper side beam 1 of the cabin to accommodate the "head" of the positioning post 42, thereby making the fixing plate 41 and the upper side beam 1 of the cabin fit together perfectly, ensuring the reliability of the installation and fixing of the fixing plate 41 on the upper side beam 1 of the cabin.

[0084] In this embodiment, it is still by Figures 1 to 4 As shown, in some exemplary embodiments, preferably, the positioning bracket 4 is also arranged near the front end of the upper beam 1 of the engine compartment. At the same time, a connecting bracket 11 is also provided at the end of the front end of the upper beam 1 of the engine compartment. Furthermore, the connecting member 3 further includes a second connecting member 32 along the vertical direction of the vehicle to fix the upper beam 2 of the radiator and the connecting bracket 11 together.

[0085] At this time, by setting a connecting bracket 11 at the front end of the upper beam 1 of the engine compartment, and by fixing the upper beam 2 of the radiator and the connecting bracket 11 together through the second connecting member 32, it can be understood that, in conjunction with the first connecting member 31, it can increase the reliability of the connection arrangement of the upper beam 2 of the radiator on the upper beam 1 of the engine compartment, and help improve the stability of the radiator arrangement at the front of the vehicle body.

[0086] In this embodiment, the connector 3 includes a first connector 31 and a second connector 32. In some exemplary embodiments, the first connector 31 may be a plurality of connectors spaced apart along the length of the upper beam 2 of the radiator, and referencing... Figure 2 , Figure 3 as well as Figures 7 to 9 As shown, each of the first connectors 31 and the second connectors 32 are also arranged in a staggered manner relative to the center line of the upper beam 2 of the radiator.

[0087] Specifically, the centerline of the upper crossbeam 2 of the radiator is the centerline of the upper crossbeam 2 of the radiator located in the front-rear direction of the vehicle. Figures 7 to 9 Taking the cross-sectional shape of the upper beam 2 of the radiator as an example, it is also the center line in the width direction of the upper beam 2 of the radiator.

[0088] By arranging multiple first connectors 31 at intervals, and by staggering the center lines of each connector 3 relative to the center lines of the radiator upper crossbeam 2, the deformation resistance of the end position where the radiator upper crossbeam 2 connects to the engine compartment upper side beam 1 can be improved. This can effectively prevent deformation at the connection position between the radiator upper crossbeam 2 and the engine compartment upper side beam 1 during a vehicle collision, reduce the deformation tendency, and improve the structural stability of the radiator upper crossbeam 2.

[0089] In this embodiment, in some exemplary implementations, the first connector 31 and the second connector 32 may both be made of connecting bolts. Using connecting bolts for each connector 3 has the advantages of simple structure, easy operation, and low cost. It also obviously enables the detachable design of the radiator's upper beam 2, facilitating later maintenance and repair.

[0090] In addition, see also Figure 7 and Figure 8 As shown, in some exemplary embodiments, the radiator upper beam 2 of this embodiment may be a tube beam, and based on this, connecting sleeves 6 corresponding to each connecting member 3 may also be provided in the radiator upper beam 2, and each connecting member 3 is passed through the corresponding connecting sleeve 6.

[0091] It is understandable that, based on the use of a tubular beam for the upper beam 2 of the radiator, by setting a connecting sleeve 6 inside the upper beam 2 of the radiator and allowing each connecting piece 3 to pass through the corresponding connecting sleeve 6, it can obviously increase the structural strength of the connection position between the upper beam 2 of the radiator and the upper side beam 1 of the engine compartment, improve the overall rigidity of the connection point between the upper beam 2 of the radiator and the upper side beam 1 of the engine compartment, and thus help to improve the stability of the connection between the upper beam 2 of the radiator and the upper side beam 1 of the engine compartment.

[0092] In this embodiment, the upper crossbeam 2 of the radiator is still based on a tubular beam. In some exemplary embodiments, preferably, the upper crossbeam 2 of the radiator can be a hot-expansion tube. In this way, using a hot-expansion tube for the upper crossbeam 2 of the radiator facilitates the cross-sectional design and forming of the upper crossbeam 2 of the radiator, and also helps to ensure the structural performance of the upper crossbeam 2 of the radiator.

[0093] In this implementation, it will continue to be... Figures 1 to 3 and combined Figures 10 to 12As shown, based on the connection arrangement of the radiator upper crossbeam 2 on the nacelle upper side beam 1, that is, based on the radiator upper crossbeam 2 being supported by the nacelle upper side beams 1 on both the left and right sides, in some exemplary embodiments, for example, a side beam support part 7 may be provided at the bottom of the front end of each side nacelle upper side beam 1.

[0094] The aforementioned side beam support 7 is used to support the front end of the upper side beam 1 of the engine compartment on the longitudinal beam of the engine compartment in the front engine compartment of the vehicle body. Structurally, the aforementioned side beam support 7 may include, for example, a first support plate 71 and a second support plate 72 arranged opposite to each other. The tops of the first support plate 71 and the second support plate 72 are both connected to the bottom of the upper side beam 1 of the engine compartment, and the lower parts of the first support plate 71 and the second support plate 72 are both connected to the side of the longitudinal beam of the engine compartment. At the same time, a cavity Q is also formed between the first support plate 71 and the second support plate 72.

[0095] Thus, by connecting the side beam support 7 formed by the first support plate 71 and the second support plate 72, and forming a cavity Q within the side beam support 7, this embodiment enables the side beam support 7 to have good structural strength. As a result, it can reliably support the front end of the side beam 1 on the engine compartment, i.e., the upper crossbeam 2 of the radiator, by means of the engine compartment longitudinal beam, thereby ensuring the stability of vehicle components such as the radiator installed on the upper crossbeam 2 of the radiator.

[0096] It is worth noting that, regarding the vehicle front-end structure of this embodiment, based on the above exemplary embodiments, in specific implementation, as a preferred embodiment, it is still composed of...
