Description

Technical Field

[0001] This utility model relates to the field of electric vehicle wheel hub heat dissipation technology, specifically an electric vehicle wheel hub with an adjustable radiator assembly. Background Technology

[0002] In-wheel motors, as an important drive system for electric vehicles, are widely used due to their compact structure, high transmission efficiency, and ease of integration into the vehicle layout. However, the high integration of drive, transmission, and braking devices within the limited space of the wheel hub results in high power density and significant heat generation issues. During sustained high-load operation, such as high-speed cruising, hill climbing, or rapid acceleration, the motor generates substantial heat. If this heat cannot be dissipated promptly and effectively, the motor temperature will rise sharply, leading to demagnetization of permanent magnets, aging of insulation materials, decreased efficiency, and even motor burnout, seriously threatening the vehicle's operational safety and reliability.

[0003] Currently, the main heat dissipation solutions for hub motors rely on natural convection and radiation heat dissipation between the motor housing and the surrounding air. However, hub motors are completely exposed to the outside, and cannot effectively protect against rainwater or mud when driving on rainy or muddy roads, which can easily lead to problems such as water ingress into the motor.

[0004] Therefore, an electric vehicle wheel hub with an adjustable radiator assembly is needed to improve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an electric vehicle wheel hub with an adjustable radiator assembly to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An electric vehicle wheel hub with an adjustable radiator assembly, comprising: A set of heat dissipation components, two of which are respectively disposed on both sides of the hub body and connected by several connecting rods, and the heat dissipation components have an installation space inside; An adjusting element is rotatably disposed inside the installation space.

[0007] As a preferred embodiment of this utility model, the heat dissipation component includes an outer ring, an inner plate is disposed inside the outer ring, a connecting plate is connected between the outer ring and the inner plate, and a plurality of heat dissipation grooves are formed on the connecting plate.

[0008] As a preferred embodiment of this utility model, the installation space is a sandwich layer formed inside the connecting plate.

[0009] As a preferred embodiment of this utility model, the outer ring has an annular groove that communicates with the interlayer.

[0010] As a preferred embodiment of this utility model, the adjusting member includes a convex ring rotatably connected to the inner plate, a connecting ring fixedly connected to one end of the convex ring, and a baffle fixedly connected to the end of the connecting ring.

[0011] As a preferred embodiment of this utility model, a groove is provided on the outer side of the inner plate, and a plurality of mounting grooves are provided at equal intervals inside the groove. An internal thread groove corresponding to the mounting groove is provided at the end of the connecting ring, and a screw is connected between the mounting groove and the internal thread groove.

[0012] As a preferred embodiment of this utility model, a sealing groove is provided on one side of the inner side of the outer ring, and a sealing ring is provided in the sealing groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention effectively enhances the protection capability of hub motors in complex environments.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] Please see Figure 1-5 This utility model provides a technical solution: In Example 1, the radiator assembly mainly comprises two parts: a heat dissipation component and an adjustment component. A set of two heat dissipation components is provided, respectively installed on the left and right sides of the wheel hub body 14. The two heat dissipation components are fixedly connected by several evenly distributed connecting rods 10, thus forming a rigid integral structure that wraps around the outside of the wheel hub. This not only ensures the structural stability of the radiator assembly itself but also effectively conducts the heat generated on both sides of the wheel hub to the heat dissipation components for dissipation.

[0021] Each heat sink includes an annular outer ring 1 and an inner plate 2 located in the central area. The outer ring 1 and the inner plate 2 are connected by a radially arranged connecting plate 8. On the connecting plate 8, multiple through heat dissipation grooves 7 are opened in the circumferential direction. These heat dissipation grooves 7 form the main channel for airflow to enter the internal space of the hub. In order to accommodate the adjustment component, a hollow interlayer 9 is carefully designed inside the connecting plate 8. The interlayer 9 surrounds the inner plate 2 to form an annular installation space.

[0022] The adjusting member is rotatably disposed inside the aforementioned interlayer 9. Specifically, the adjusting member includes a convex ring 5 that is rotatably connected to the inner plate 2 via a bearing or bushing structure. A portion of the convex ring 5 is accommodated within the interlayer 9 and can be driven by external force to rotate relative to the heat dissipation component. At the inner end of the convex ring 5, a connecting ring 11 is fixedly connected, and an annular baffle 13 is fixedly installed at the end of the connecting ring 11. Example

[0023] Based on Example 1, this embodiment further optimizes the fixing and adjustment method of the adjusting component.

[0024] like Figure 4 As shown, an annular groove 3 is formed on the outer end face of the inner plate 2. At the bottom of the groove 3, a plurality of mounting grooves 4 are formed at equal intervals along the circumference. Correspondingly, an internal thread groove 12 corresponding to the position of these mounting grooves 4 is also formed on the end face of the connecting ring 11 of the adjusting member.

[0025] During initial installation or when manual adjustment of the fixed angle is required, first rotate the convex ring 5 and its connected baffle 13 to the desired angle position. Then, use a screw to pass through the mounting groove 4 on the inner plate 2 and screw it into the internal thread groove 12 on the end face of the connecting ring 11, thereby securing the adjusting component at the predetermined angle. This design provides a simple, reliable, and cost-effective positioning method. Users or maintenance personnel can manually select and fix the optimal guide angle according to seasonal changes or main road conditions.

[0026] To improve the durability of the components in harsh environments, a sealing groove is provided on the inner side of the outer ring 1 that contacts the hub housing. A sealing ring is embedded in the groove. This sealing ring can effectively prevent rainwater, mud and other contaminants from entering the hub from the joint between the radiator assembly and the hub, thus protecting the motor and other precision components.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
