Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle technology, specifically to a tooling for testing new energy vehicles. Background Technology

[0002] In the production of new energy vehicles, it is necessary to test the vehicle's chassis suspension. Traditional testing methods for gasoline-powered vehicles involve using specialized clamping equipment to hold the vehicle against the chassis skirts, followed by hoisting and testing. However, for new energy vehicles, to facilitate battery pack installation, the traditional chassis skirts are removed, and the battery pack is installed in the skirt's original location. While this method allows for successful battery pack installation, the removal of the skirts eliminates the clamping points on the chassis, creating inconvenience for testing the chassis suspension of new energy vehicles. Utility Model Content

[0003] To address the shortcomings of existing technologies, the technical problem this invention aims to solve is to provide a tooling for testing new energy vehicles, which facilitates the testing of vehicle chassis suspension.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a tooling for testing new energy vehicles, comprising: The mounting plate has two surfaces along its thickness direction, namely a first surface and a second surface, wherein the first surface is a plane. A clamping part, fixed to the second surface, is used for clamping the hoisting equipment; The mounting hole penetrates the mounting plate, and the axis of the mounting hole is perpendicular to the first surface; The connector allows the mounting plate to be fixed to the vehicle chassis via the mounting holes; A clearance portion is disposed on the first surface and adjacent to the mounting hole to avoid protrusions on the part of the vehicle chassis that connects to the connector.

[0005] Furthermore, there are two mounting holes, which are arranged opposite each other at both ends of the mounting plate, and the connector is provided accordingly.

[0006] Furthermore, the avoidance portion is a recessed groove.

[0007] Furthermore, the groove is a cylindrical hole.

[0008] Furthermore, the mounting hole is a bolt hole, and the connector is a connecting bolt that matches the bolt hole.

[0009] Furthermore, the bottom surfaces of the bolt holes are located on the same plane and parallel to the first surface, and have the same hole diameter. Furthermore, the clearance portion is concentrically arranged with the mounting hole.

[0010] The beneficial effects of this utility model are: The aforementioned tooling for testing new energy vehicles is used by ensuring the first surface is tightly fitted against the horizontal surface of the vehicle chassis, and that the clearance portion avoids any protrusions on the chassis where it connects to the connector. Then, the connector is passed through the mounting hole and connected to the connection point on the vehicle chassis. This completes the installation of the tooling. After installation, the clamping tool of the lifting equipment is gripped on the clamping part, and the lifting equipment is started to lift the vehicle chassis suspension to the required position for testing.

[0011] By using the above-mentioned tooling and connecting it to the automobile chassis, the inspection of the automobile chassis suspension can be facilitated. At the same time, the connection between the connecting parts of this tooling and the automobile chassis adopts a mechanical connection method, avoiding the installation difficulties, stress concentration and vehicle deformation problems caused by traditional welding methods.

Detailed Implementation

[0014] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the invention; therefore, the invention is not limited to the specific embodiments disclosed below.

[0015] In the production of new energy vehicles, it is necessary to test the chassis suspension of multiple vehicles. The traditional testing method for gasoline vehicles involves using specialized clamping equipment to hold the vehicle to the side skirts of the chassis, followed by suspension testing using hoisting equipment. However, for new energy vehicles, to facilitate the installation of the battery pack, the traditional side skirts on the chassis are removed, and the battery pack is installed in the side skirt location. While this method allows for successful battery pack installation, the removal of the side skirts eliminates the clamping points on the chassis, causing inconvenience for testing the chassis suspension of new energy vehicles.

[0016] Therefore, for ease of inspection, it is necessary to add appropriate tooling for clamping the lifting equipment to the chassis of the new energy vehicle.

[0017] Furthermore, experiments and research have shown that in current technologies, aluminum alloys or composite materials are extensively used to ensure the lightweighting of new energy vehicles. However, welding these materials is difficult, and welding can reduce their strength. Additionally, from a safety perspective, the battery pack needs to withstand collisions. If there are welded points at the bottom, stress concentration may occur during a collision, leading to structural failure and even causing the battery pack to explode.

[0018] In addition, from a manufacturing process perspective, welding requires higher precision and different equipment, which can lead to difficulties in standardization, resulting in increased production costs. At the same time, welding may cause deformation, affecting the overall precision of the vehicle.

[0019] Based on the above reasons, this utility model proposes a new testing fixture for new energy vehicles. This testing fixture for new energy vehicles is used for testing the chassis suspension of automobiles and includes a mounting plate 100, a clamping part 200, a mounting hole 300, a connecting piece 400, and a clearance part 500.

[0020] Please see Figure 1 and Figure 2 Specifically, the mounting plate 100 has two surfaces along its thickness direction, namely a first surface 110 and a second surface 120, where the first surface 110 is a plane. A clamping part 200 is fixed to the second surface 120 for clamping lifting equipment. A mounting hole 300 penetrates the mounting plate 100, and the axis of the mounting hole 300 is perpendicular to the first surface 110. The connector 400 can fix the mounting plate 100 to the vehicle chassis through the mounting hole 300. A clearance part 500 is provided on the first surface 110 and adjacent to the mounting hole 300; the clearance part 500 is used to avoid protrusions on the vehicle chassis at the connection point with the connector 400.

[0021] In use, the first surface 110 is tightly fitted against the horizontal surface of the vehicle chassis, ensuring that the clearance portion 500 avoids any protrusions on the vehicle chassis where it connects to the connector 400. Then, the connector 400 is passed through the mounting hole 300 and connected to the connection portion of the vehicle chassis. This completes the installation of the fixture. After installation, the clamping tool of the lifting equipment is clamped onto the clamping portion 200, and the lifting equipment is started to lift the vehicle chassis suspension to the required position for testing.

[0022] By using the above-mentioned tooling and connecting it to the automobile chassis, the inspection of the automobile chassis suspension can be facilitated. At the same time, the connection between the connecting part 400 of this tooling and the automobile chassis adopts a mechanical connection method, avoiding the installation difficulties, stress concentration and vehicle deformation problems caused by traditional welding methods.

[0023] In practical implementation, two mounting holes 300 can be set, and the connecting parts 400 are set accordingly to improve the stability of the tooling.

[0024] Furthermore, the study also found that in the field of new energy vehicles, aluminum alloys or composite materials are used extensively to ensure the lightweighting of new energy vehicles. Since it is difficult to weld tooling on these materials, or welding will reduce the strength of the materials, bolted connections may be more suitable for the connection and installation of these materials in the assembly of vehicle chassis-related components in the field of new energy vehicles. At the same time, bolted connections can also maintain the integrity of the structure.

[0025] Meanwhile, welded joints can generate stress concentrations upon impact, leading to structural failure, while bolted connections may offer better energy absorption and distribution, reducing the impact on the battery pack. Furthermore, bolted assemblies and bolt holes are likely to be easier to standardize in production, reducing costs. Additionally, bolted connections may offer greater flexibility and easier adjustments.

[0026] Therefore, in this embodiment, the mounting hole 300 is a bolt hole. The connector 400 is a connecting bolt that matches the bolt hole.

[0027] Bolted connections can avoid stress concentration, and are easy and flexible to assemble, further reducing assembly costs.

[0028] As a preferred embodiment, in specific implementation, it should be ensured that the bottom surfaces of the bolt holes are located on the same plane, parallel to the first surface 110, and have the same hole diameter. This improves the adaptability and stability of the entire tooling. Furthermore, as a more efficient implementation, the clearance portion can be concentrically positioned with the mounting hole 300. During machining, this allows for completion of machining in a single process, reducing the need for repeated clamping and alignment. Additionally, it improves the stability of bolt fixing.

[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
