Technical Field
[0001] This utility model relates to the field of electrical control box equipment technology, and more specifically to a cover plate for a new energy electrical control box. Background Technology
[0002] Traditional new energy vehicle control box covers are generally made of stainless steel stamping to form a specific single-layer product structure so that the control box can be fastened. However, stainless steel cover products are relatively heavy, which does not meet the lightweight design of new energy vehicles. At the same time, the single-layer steel plate structure cannot effectively block and dissipate the noise and heat generated by the electronic components inside the control box, which seriously affects the service life of the control box. Utility Model Content
[0003] The technical problem to be solved by this utility model is how to improve the sound insulation performance of the electrical control box.
[0004] This utility model solves the above-mentioned technical problems through the following technical means: a new energy power control box cover, including a cover body, the cover body including an upper connector and a lower connector, the upper connector and the lower connector are pressed and fixed to form a sealed cavity structure.
[0005] By forming a sealed cavity structure on the cover plate body and setting a double-layer structure with upper and lower connectors on the cover plate body, the vibration generated when the components in the electrical control box carry current can be effectively reduced, thereby extending the product's lifespan. At the same time, it can effectively reduce noise and avoid noise pollution.
[0006] As a preferred technical solution, the upper connector and the lower connector respectively include an upper shell and a lower shell, both of which are aluminum shells.
[0007] As a preferred technical solution, the end of the upper connector facing away from the lower connector and the end of the lower connector facing away from the upper connector are both provided with convex bulges, the two convex bulges form a vacuum convex bulge, and the inner cavity of the vacuum convex bulge forms the cavity structure.
[0008] As a preferred technical solution, the upper connector and the lower connector are connected and fastened by heat pressing.
[0009] As a preferred technical solution, the connection surfaces of the upper connector and the lower connector are provided with a polyester film.
[0010] As a preferred technical solution, the vacuum convex bulge is provided with a heat dissipation convex bulge.
[0011] As a preferred technical solution, the upper connector is provided with an elastic buckle, and the lower connector is provided with a limiting groove that matches the elastic buckle.
[0012] As a preferred technical solution, the elastic buckle includes four elastic connecting parts, and the limiting groove includes through holes and slots adapted to the four elastic connecting parts.
[0013] As a preferred technical solution, the outer edge of the upper connector is further provided with a connecting buckle, and the outer edge of the lower connector is further provided with a connecting slot that matches the connecting buckle.
[0014] As a preferred technical solution, the upper connector or the lower connector, or both the upper connector and the lower connector, are provided with heat dissipation protrusions.
[0015] The beneficial effects of this utility model are as follows:
[0016] (1) In this utility model, by forming a closed cavity structure on the cover plate body and setting the cover plate body with a double-layer structure of upper connector and lower connector, the vibration generated when the components in the electrical control box carry current can be effectively alleviated, thus improving the product's lifespan. At the same time, it can effectively reduce noise and avoid noise pollution.
[0017] (2) In this utility model, the upper and lower aluminum shells are designed with convex bulges, so that the shells will form a vacuum convex bulge when they are hot-pressed together. The design of the vacuum bulge allows the heat generated by the control box during operation to act as a heat insulation and heat dissipation layer through the vacuum bulge, which can protect the product and avoid high temperature damage to the product, so that the product has excellent heat dissipation and shock absorption effect.
[0018] (3) In this utility model, the heat dissipation protrusion designed on the vacuum protrusion increases the contact area between the product and the air, thereby improving the heat dissipation effect of the product.
[0019] (4) In this utility model, the elastic buckles and slots designed on the outer edges of the aluminum upper shell and the lower shell enable the aluminum upper shell to accurately correspond to the lower shell, avoiding misalignment of the two aluminum shells. At the same time, the elastic buckles designed on the outer periphery of the aluminum upper shell, after passing through the slots of the lower shell, open outwards after hot pressing and smoothly enter the slots along the slot trajectory of the lower shell, making the fit between the upper shell and the lower shell tighter. This also prevents the aluminum upper shell and the aluminum lower shell from falling off after the product has undergone thermal expansion and contraction. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, 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.
[0025] See Figure 1 , Figure 3 A new energy power control box cover includes a cover body, which includes an upper connector and a lower connector. The upper connector and the lower connector are heat-pressed together to form a sealed cavity structure. In this embodiment, the upper connector and the lower connector respectively include an upper shell 1 and a lower shell 2. Both the upper shell 1 and the lower shell 2 are made of aluminum, which reduces the weight compared to the original stainless steel material. At the same time, a polyester film is provided on the connecting surface of the upper shell 1 and the lower shell 2. The polyester film melts when the upper shell 1 and the lower shell 2 are heat-pressed together, which improves the tightness of the connection between the upper shell 1 and the lower shell 2, thereby improving the sealing performance of the cavity structure. The double-layer structure design of the upper shell 1 and the lower shell 2 can effectively alleviate the vibration generated when the components in the power control box carry current, thereby extending the product's lifespan and effectively reducing noise to avoid noise pollution.
[0026] See Figure 1 , Figure 3 The upper shell 1 is provided with a protrusion at one end opposite to the lower shell 2, and the lower shell 2 is provided with a protrusion at one end opposite to the upper shell 1. The two protrusions form a vacuum protrusion 3. The inner cavity of the vacuum protrusion 3 forms the above-mentioned cavity structure. The vacuum protrusion 3 allows the heat generated by the electrical control box during operation to act as a heat insulation and heat dissipation layer through the vacuum protrusion 3, which can protect the product and avoid high temperature damage to the product, so that the product has excellent heat dissipation and shock absorption effect and improves the safety performance of the product.
[0027] The vacuum protrusion 3 is provided with a heat dissipation protrusion 4. In this example, the heat dissipation protrusion 4 can be provided on the protrusion of the upper shell 1 or the lower shell 2, or the heat dissipation protrusion 4 can be provided on both the upper shell 1 and the lower shell 2, which increases the contact area between the product and the air and improves the heat dissipation effect of the product.
[0028] See Figure 2 The upper shell 1 is provided with multiple elastic buckles 5, and the lower shell 2 is provided with multiple limiting grooves 6 that are adapted to the elastic buckles 5. The elastic buckles 5 are correspondingly arranged with the limiting grooves 6. The elastic buckles 5 include four elastic connecting parts. (See reference) Figure 3 The limiting groove 6 includes through holes 61 and slots 62 that are adapted to the four elastic connecting parts. In this embodiment, four slots 62 are provided, and a through hole 61 is provided at the center of each slot. The through hole 61 facilitates the passage of the four elastic connecting parts through the lower shell 2. After heat pressing, the elastic connecting parts open outwards and smoothly enter the slots 62 along the trajectory of the slots 62 on the lower shell 2, making the fit between the upper shell 1 and the lower shell 2 tighter. At the same time, it prevents the upper shell 1 and the lower shell 2 from falling off due to thermal expansion and contraction after heat pressing.
[0029] See Figure 1 , Figure 3 The upper shell 1 is also provided with a connecting buckle 7 on its outer edge, and the lower shell 2 is also provided with a connecting slot (not shown in the figure) that is adapted to the connecting buckle 7 on its outer edge, further improving the connection stability between the upper shell 1 and the lower shell 2.
[0030] 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 of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
