Description

Technical Field

[0001] This utility model belongs to the technical field of structural components for new energy vehicles, and in particular relates to a front upper crossbeam for new energy vehicles. Background Technology

[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as their power source and integrate advanced technologies in vehicle power control and drive, resulting in vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, and hydrogen engine vehicles.

[0003] Currently, the front upper crossbeam of new energy vehicles not only protects the torsional stiffness of the frame and bears longitudinal loads, but also supports the main components of the vehicle. Existing front upper crossbeams for new energy vehicles have some limitations: on the one hand, they are relatively heavy, making weight reduction difficult; on the other hand, their function is relatively limited. Although a hollow crossbeam design can achieve some degree of vehicle weight reduction, this design struggles to meet the requirements for good support performance.

[0004] In summary, the existing front upper crossbeams of new energy vehicles struggle to maintain good support while achieving lightweight design. Utility Model Content

[0005] This utility model provides a front upper crossbeam for new energy vehicles, which can solve the problem that existing front upper crossbeams for new energy vehicles are difficult to maintain a good supporting effect while achieving lightweighting.

[0006] To achieve the above objectives, according to an embodiment of the first aspect of this utility model, a front upper crossbeam for a new energy vehicle is provided, comprising an upper crossbeam, wherein the interior of the upper crossbeam is a hollow structure and a plurality of mounting grooves are provided on the bottom surface.

[0007] The reinforced buffer structure includes several connecting blocks fixedly installed in the mounting groove at the bottom of the upper crossbeam, a pressure-bearing block fixedly installed on the inner wall of the top surface of the upper crossbeam and corresponding to each connecting block, and a buffer spring fixedly installed between each pressure-bearing block and the connecting block.

[0008] A further improvement is that several assembly connectors are sequentially fixedly installed on the side and top surfaces of the upper crossbeam, and each assembly connector has an internal thread inside its port.

[0009] A further improvement is that the positions of the assembly connectors on the side and top surfaces of the upper crossbeam correspond.

[0010] A further improvement is that a connection hole is provided between the inner sides of the assembly connector.

[0011] A further improvement is that each of the aforementioned buffer springs has a guide post that is movably inserted therein, and the top surface of each guide post is connected to the bottom surface of the pressure block.

[0012] A further improvement is that each of the connecting blocks has a slot on its surface, and the bottom surface of each guide post is movably engaged in the slot.

[0013] A further improvement is that it also includes a protective coating layer, which comprises an antioxidant coating, an abrasion-resistant coating, and a stone-impact-resistant coating.

[0014] A further improvement is that the protective coating layer is applied to the exterior of the topcoat of the upper crossbeam.

[0015] A further improvement is that the wear-resistant coating is disposed between the anti-oxidation coating and the anti-stone chip coating.

[0016] A further improvement is that the wear-resistant coating is applied close to the topcoat of the upper crossbeam.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] (1) This utility model involves creating several mounting slots at the bottom of the upper crossbeam. Then, a reinforced buffer structure is formed by assembling a connecting block, guide post, buffer spring, and bearing block, and inserted into the upper crossbeam through the mounting slots until the top surface of the bearing block is in close contact with the inner wall of the upper crossbeam. By installing several such reinforced buffer structures, the upper crossbeam can be structurally reinforced during use. Under the guidance of the guide post, the upper crossbeam can achieve limited guidance. This design allows the upper crossbeam to achieve lightweighting of the vehicle body while using a hollow structure, thus meeting the requirements for good support and buffering effects, effectively improving the service life of the upper crossbeam.

[0019] (2) This utility model applies a protective coating layer to the exterior of the topcoat of the upper crossbeam. This protective coating layer consists of an anti-oxidation coating, an abrasion-resistant coating, and an anti-stone-impact coating. These three coating layers together give the upper crossbeam excellent abrasion resistance and scratch resistance, effectively resisting the impact of gravel and mechanical wear, and further extending the service life of the upper crossbeam.

[0026] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] like Figures 1 to 4 As shown, a front upper crossbeam of a new energy vehicle includes an upper crossbeam 1. The interior of the upper crossbeam 1 is a hollow structure. The cross section of the upper crossbeam 1 is trapezoidal. Several mounting slots 12 are opened on the bottom surface. Several assembly connectors 11 are fixedly installed on the side and top surface of the upper crossbeam 1 in sequence. Each assembly connector 11 has an internal thread in its port.

[0028] It should be noted that the positions of the assembly connectors 11 on the side and top of the upper crossbeam 1 are corresponding, and there are connection holes between the inner sides of the assembly connectors 11. The assembly connectors 11 are used for installation and connection with the car engine compartment, and the connection holes can be connected to other components.

[0029] The reinforced buffer structure 2 includes several connecting blocks 21 fixedly installed in the mounting grooves 12 at the bottom of the upper crossbeam 1, pressure blocks 22 fixedly installed on the inner wall of the top surface of the upper crossbeam 1 corresponding to each connecting block 21, and buffer springs 23 fixedly installed between each pressure block 22 and the connecting block 21. Before assembly and use, several mounting grooves 12 are opened at the bottom of the upper crossbeam 1, and the connecting blocks 21, guide posts 24, buffer springs 23, and pressure blocks 22 are arranged to form a reinforced buffer structure 2. This reinforced buffer structure 2 is inserted into the upper crossbeam 1 through the mounting grooves 12 until the top surface of the pressure block 22 is in close contact with the inner wall of the upper crossbeam 1, so that each individual reinforced buffer structure 2 is spaced apart between adjacent assembly connectors 11. Then, screws are used to fix the upper crossbeam 1 to the pressure block 22, and at the same time, the connecting blocks 21 are fixedly connected to the bottom of the upper crossbeam 1. By installing several such reinforced buffer structures 2, the upper crossbeam 1, during use, achieves lightweighting of the vehicle body through a hollow structure, while also meeting the requirements for good support and buffering effect, thereby effectively improving the service life of the upper crossbeam 1.

[0030] As a preferred embodiment, each buffer spring 23 has a guide post 24 that is movably inserted inside it. The top surface of each guide post 24 is connected to the bottom surface of the pressure block 22. The surface of each connecting block 21 is provided with a slot 201. The bottom surface of each guide post 24 is movably locked in the slot 201. Under the guidance of the guide post 24, it is limited and guided, so that the upper crossbeam 1 can achieve a stable buffering effect.

[0031] like Figure 4 As shown in this embodiment, another implementation scheme is also provided, as detailed below:

[0032] The protective coating layer 3 includes an anti-oxidation coating 31, an abrasion-resistant coating 32, and an anti-stone-impact coating 33. The protective coating layer 3 is applied to the exterior of the topcoat of the upper crossbeam 1.

[0033] Specifically, the wear-resistant coating 32 is disposed between the anti-oxidation coating 31 and the anti-stone impact coating 33. The wear-resistant coating 32 is close to the topcoat layer 101 of the upper crossbeam 1. Through these three layers of coating, the excellent wear resistance and scratch resistance of the upper crossbeam 1 can be enhanced, thereby effectively resisting the impact of gravel and mechanical wear, and further extending the service life of the upper crossbeam 1.

[0034] like Figures 1 to 4 As shown in this embodiment, it should also be noted that the actual dimensions and shapes of the components in the application document are selected and installed according to the actual needs on site. Additionally, it should be noted that this application document only addresses the shortcomings of existing front upper crossbeams for new energy vehicles, which struggle to maintain good support while achieving lightweighting; it does not cover other aspects. The working principle of this new energy vehicle front upper crossbeam is described below:

[0035] Before using this novel design, firstly, several mounting slots 12 are made at the bottom of the upper crossbeam 1. Next, a reinforced buffer structure 2 is formed by assembling the connecting block 21, guide post 24, buffer spring 23, and bearing block 22, and inserted into the upper crossbeam 1 through the mounting slots 12 until the top surface of the bearing block 22 is in close contact with the inner wall of the upper crossbeam 1. Then, screws are used to fix the upper crossbeam 1 to the bearing block 22, and simultaneously, the connecting block 21 is fixedly connected to the bottom of the upper crossbeam 1.

[0036] This novel design, by installing several such reinforced buffer structures 2, allows the upper crossbeam 1 to be structurally reinforced during use. Guided by the guide pillars 24, the upper crossbeam 1 achieves limiting and guiding. This design enables the upper crossbeam 1 to achieve lightweighting of the vehicle body while employing a hollow structure, thus meeting the requirements for good support and buffering effects, effectively improving the service life of the upper crossbeam 1.

[0037] In addition, this invention also applies a protective coating layer 3 to the exterior of the topcoat of the upper crossbeam 1. This protective coating layer 3 consists of an anti-oxidation coating 31, an abrasion-resistant coating 32, and an anti-stone-impact coating 33. These three coatings together give the upper crossbeam 1 excellent abrasion resistance and scratch resistance, effectively resisting the impact of gravel and mechanical wear, and further extending the service life of the upper crossbeam 1.

[0038] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
