Description

Technical Field

[0001] This utility model relates to the field of electric vehicle technology, specifically to an integrated protective plate for electric vehicles. Background Technology

[0002] The existing seat buckets of electric vehicles are generally made of a single piece of plastic. Once damaged, the entire unit needs to be replaced, resulting in high maintenance costs. In addition, with the introduction of the new national standard, the total mass of plastic used in electric vehicles must not exceed 5.5% of the total vehicle mass. Therefore, in order to reduce maintenance costs and comply with the requirements of the new national standard, an integrated protective plate was designed for this electric vehicle. Utility Model Content

[0003] The purpose of this utility model is to provide an integrated protective plate for electric vehicles. The one-piece molded seat bucket is designed as a separate protective plate, which makes the structure flexible, easy to maintain and reduces maintenance costs. At the same time, the baffle is designed to be made of metal, which greatly reduces the amount of plastic used and meets the requirements of the new national standard.

[0004] This utility model provides the following technical solution: an integrated protective plate for electric vehicles, including a base and a baffle. The lower end of the baffle is formed with an arc-shaped connecting plate. The surface of the connecting plate is symmetrically formed with positioning grooves, a first insertion hole, and a second insertion hole from both sides toward the center. The inner wall edge of the base is symmetrically formed with positioning protrusions, a first buckle, and a second buckle from both sides toward the center. The positioning protrusions correspond to the positioning grooves. A threaded hole is opened in the center of the positioning protrusions. The baffle and the connecting plate are connected by threads. The first insertion hole and the first buckle are inserted into each other, and the second buckle and the second insertion hole are inserted into each other.

[0005] According to the above technical solution, the baffle includes a symmetrical left side plate and a right side plate. The positioning groove, the first insertion hole and the second insertion hole are symmetrically distributed on the left side plate and the right side plate, and the baffle is designed as a split type. At the same time, the first buckle, the second buckle and the positioning protrusion on the base will position the left side plate and the right side plate to ensure that the two are attached together. The left side plate and the right side plate can be connected and positioned together by spot welding.

[0006] According to the above technical solution, side folds are formed at the junction of the left and right side plates, and the side folds are welded together to enhance the connection strength between the left and right side plates.

[0007] According to the above technical solution, the first insertion hole is a vertical hole, the second insertion hole is a horizontal insertion hole, the first buckle is a vertical buckle plate, and the second insertion hole is a horizontal buckle plate. By using the connection between the insertion holes and buckles in different directions, the looseness between the baffle and the base is reduced, and the stability and strength of the connection are improved.

[0008] According to the above technical solution, the upper ends of the left and right side panels are both formed with top folded edges. Each top folded edge has two strip plates protruding inward. The two strip plates are vertically distributed and connected to the seat cushion plate, so that the connection position between the strip plates and the seat cushion plate is evenly distributed, thereby improving the connection strength between the strip plates and the seat cushion plate.

[0009] According to the above technical solution, the base is made of plastic, and the left and right side panels are made of metal. The metal material enhances the protection of the seat bucket while reducing the amount of plastic material used, thus meeting the new national standard requirements.

[0010] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0011] (1) The one-piece molded seat bucket is designed as a split guard plate, which makes the structure flexible, easy to maintain and reduces maintenance costs.

[0012] (2) Moreover, one component is made of plastic and the other is made of metal, which reduces the use of plastic materials and meets the new national standard requirements for electric vehicles;

[0013] (3) At the same time, the base can position the left and right side plates, which improves the forming accuracy of the baffle and ensures the welding stability between the left and right side plates. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: an integrated protective plate for an electric vehicle, including a base 2 and a baffle 1. The bottom of the base 2 is fixed to the vehicle frame. The lower end of the baffle 1 is formed with an arc-shaped connecting plate, which is used to connect to the inner wall of the base 2. The surface of the connecting plate is symmetrically formed with positioning grooves 111, first insertion holes 112 and second insertion holes 113 from both sides to the center. The inner wall edge of the base 2 is symmetrically formed with positioning protrusions 21, first buckles 22 and second buckles 23 from both sides to the center. The positioning protrusions 21 correspond to the positioning grooves 111. A threaded hole is opened in the center of the positioning protrusions 21, which is embedded in the positioning grooves 111. Through holes are also opened on the side of the positioning grooves. The baffle 1 and the connecting plate... The baffle 1 is connected to the two ends of the base 2 via a threaded connection. The first insertion hole 112 and the first buckle 22 are inserted, and the second buckle 23 and the second insertion hole 113 are inserted. This ensures the accurate installation and positioning of the base 2 and the baffle 1. At the same time, the split-type protective plate has higher strength than the existing one-piece molded seat bucket. In case of vehicle tilting or damage, it can be repaired by replacing parts. Compared with replacing the whole seat bucket, the maintenance cost is low. The base 2 is made of plastic, while the left side plate 11 and the right side plate 12 are made of metal. While improving the strength of the protective plate, the amount of plastic material used is reduced, so that the amount of plastic used in the whole vehicle does not exceed 5.5% of the total vehicle weight, which meets the requirements of the new national standard.

[0022] The baffle 1 includes a symmetrical left side plate 11 and a right side plate 12. The positioning groove 111, the first insertion hole 112 and the second insertion hole 113 are symmetrically distributed on the left side plate 11 and the right side plate 12. The baffle 1 is designed as a split type, which makes the structure flexible and the installation and positioning convenient. The left side plate 11 and the right side plate 12 are positioned by the symmetrical first insertion buckle 22 and the second insertion buckle 23, ensuring that the left side plate 11 and the right side plate 12 fit together.

[0023] Side folds 14 are formed at the junction of the left side plate 11 and the right side plate 12. The two sides of the side folds 14 of the left side plate 11 and the right side plate 12 are close to each other and welded together.

[0024] The first insertion hole 112 is a vertical hole, and the second insertion hole 113 is a horizontal insertion hole. The first buckle 22 is a vertical buckle plate, and the second insertion hole 113 is a horizontal buckle plate. The vertically distributed first insertion hole 112 and the horizontally distributed second insertion hole 113 are used to position the device in different directions, further enhancing the limiting of the left side plate 11 or the right side plate 12 and preventing the baffle 1 from becoming loose on the base 2.

[0025] like Figure 2 and 3 As shown, the upper ends of the left side plate 11 and the right side plate 12 are both formed with top folded edges 13. Two strip plates 15 protruding inward are formed on each top folded edge 13. The two strip plates 15 are vertically distributed. The seat plate is connected to the strip plate 15 by bolts. The vertically distributed strip plates 15 make the connection position between the seat plate and the strip plate 15 evenly distributed, which enhances the connection strength with the seat plate.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
