Abstract
Description
Technical Field
[0001] This utility model relates to an electric vehicle, and more particularly to a controller assembly for a food delivery electric vehicle. Background Technology
[0002] Electric vehicles are powered by batteries and typically require a controller to manage their operation and the function of their electrical components. In the food delivery industry, delivery drivers usually use ordinary electric vehicles. Due to the nature of their work, there are specific requirements for the carrying capacity and range of these vehicles, and ordinary electric vehicles are not well-suited to the needs of this industry. To ensure that electric vehicles meet the actual demands of food delivery, larger batteries are generally required; otherwise, the effective lifespan of the vehicle will be affected. When an electric vehicle is used under heavy load for extended periods, the controller will continuously operate on the electrical components, resulting in a significant heat load on the controller and posing a challenge to its stability.
[0003] Chinese patent document (publication number: CN 206686506U) discloses a heat dissipation structure for an electric vehicle controller, including a circuit board and a housing, and a heat dissipation assembly connected to the circuit board. One side of the heat dissipation assembly abuts against the copper plate, and the other side abuts against the housing. The side of the heat dissipation assembly closest to the copper plate is an insulating surface. Heat generated on the circuit board is transferred to the heat dissipation assembly through the copper plate, and the heat dissipation assembly transfers the heat to the outside of the housing through the housing. This invention also provides an electric vehicle controller including the aforementioned heat dissipation structure. The heat dissipation structure and the electric vehicle controller provided by this invention rapidly transfer heat generated on the circuit board to the outside of the housing, reducing the operating temperature of the circuit board and extending the service life of the electric vehicle controller.
[0004] This heat dissipation structure discloses a controller, in which the heat dissipation component adopts an air-cooled heat sink fin. This heat dissipation component is often limited by external weather conditions and sometimes cannot achieve sufficient heat dissipation for the controller, which will affect the stability of the controller's use. If applied to the long-term use conditions in the food delivery industry, the stability of the controller's use cannot be guaranteed, and it is also prone to damage. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a controller assembly for electric delivery vehicles. This assembly enables the controller to dissipate heat effectively during the operation of the electric vehicle, resulting in good stability of the controller and helping to ensure the service life of the controller.
[0006] To solve the aforementioned technical problem, the present invention provides the following technical solution: a controller assembly for a delivery electric vehicle, comprising a controller connected to a mounting bracket, a wind-cooled radiator attached to the controller, a plurality of heat dissipation fins on the outer surface of the radiator, the heat dissipation fins being arranged side-by-side at intervals along the width direction of the vehicle frame, and air ducts forming between adjacent heat dissipation fins, characterized in that a plurality of fans are provided on the mounting bracket, the fans being located below the radiator, the air outlets of the fans facing the heat dissipation fins, and the fans being arranged in a row along the width direction of the vehicle frame.
[0007] The fan is electrically connected to the controller. It can start automatically during electric vehicle operation, or a temperature sensor can be installed on the controller to control the fan, activating it when the controller exceeds a set temperature. This causes the fan to blow air onto the heatsink fins, accelerating heat dissipation from the radiator. The overall fan layout is adapted to the radiator's dimensions along the vehicle frame width, and the fan's airflow area essentially covers all the heatsink fins. The fans are positioned close to the heatsink fins, with the spacing between them on the order of centimeters.
[0008] Furthermore, the mounting bracket includes an upper crossbeam and a lower crossbeam, both of which are bridged to the frame along its width. The upper crossbeam is straight, and the lower crossbeam is U-shaped. A fixing plate is bridged to the upper and lower crossbeams, and the controller is connected to the fixing plate. The controller is mounted and fixed using two crossbeams and a fixing plate, resulting in a simple structure and good positional stability of the controller on the frame.
[0009] Furthermore, the mounting bracket is positioned under the seat cushion of the delivery electric vehicle, with the fixing plate angled. Positioning the controller under the seat cushion and angled fixing plate effectively utilizes the space within the electric vehicle, resulting in a compact overall structure.
[0010] Furthermore, a window is provided in the middle of the fixing plate, and several strip-shaped openings are provided on the outside of the window on the fixing plate. The setting of the window and openings can reduce the weight of the fixing plate and lighten the load on the electric vehicle, and can also play a certain role in heat dissipation of the controller.
[0011] Furthermore, an L-shaped plate-like mounting base is provided at the lower end of the mounting bracket, and the fan is installed inside the mounting base. This mounting base can well accommodate the installation of the fan, the fan has good positional stability on the mounting base, and the fan's air outlet can be adapted to the setting direction of the heat sink fins.
[0012] Furthermore, the fan is fixedly attached to the mounting base, which has several through-holes at positions corresponding to the fan. These holes are arranged in groups corresponding to the fan, and each group of holes is arranged in a circular pattern. The arrangement of these holes ensures the fan is securely attached to the mounting base, providing good positional stability and not affecting its normal operation.
[0013] Furthermore, a temperature sensor is included in the controller to control the fan's operation. When the temperature sensor detects that the controller temperature is higher than the set temperature, it will activate the fan, thereby effectively saving energy and ensuring the controller's operational stability.
[0014] Compared with the prior art, the present invention has the following advantages: In this controller assembly, the heat dissipation effect is improved by the arrangement of several heat dissipation fins and the combination of a fan, preventing the controller from experiencing poor stability due to excessive temperature. The reasonable arrangement of the heat sink, controller, and fan ensures effective heat dissipation for the controller. Attached Figure Description

Detailed Implementation
[0019] Referring to the attached diagram in the instruction manual, the controller assembly of this electric delivery vehicle is mounted on frame 1. Figure 1 As shown in the image, the controller assembly is located inside the frame 1, and the seat of the electric vehicle is located above the controller assembly.
[0020] The controller assembly includes a controller 9, which is electrically connected to the corresponding electrical components on the electric vehicle via a wiring structure 10. The controller 9 has a flat structure and is attached to a mounting bracket. A wind-cooled radiator 8 is attached to the outer surface of the controller 9. Several heat dissipation fins 81 are provided on the outer surface of the radiator 8. These fins 81 are arranged side-by-side at intervals along the width direction of the frame 1, and their length direction is generally perpendicular to the width direction of the frame 1. Air channels are formed between adjacent heat dissipation fins 81. Airflow within these channels carries away the heat accumulated on the heat dissipation fins 81, achieving a wind-cooling effect on the controller 9. Several fans 7 are mounted on the mounting bracket, located below the radiator 8. The air outlets 61 of the fans 7 face the heat dissipation fins 81, and these fans 7 are arranged in a row along the width direction of the frame 1. Fan 7 blows air onto the heat sink 81 from below, with some airflow circulating within the air duct, carrying heat from the heat sink 81 to the outside, thus cooling the controller 9 via the heat sink 8. The operation of fan 7 can be automatically controlled. A temperature sensor is installed in the controller 9 to detect its operating temperature. When the controller 9 reaches a set temperature value, it will control the fan 7 to start, thus enabling the temperature sensor to control the operation of fan 7.
[0021] The mounting frame includes an upper crossbeam 5 and a lower crossbeam 2, which are arranged side-by-side at intervals. Both the upper crossbeam 5 and the lower crossbeam 2 are bridged onto the frame 1 along its width. The upper crossbeam 5 is straight, and the lower crossbeam 2 is U-shaped. A fixing plate 3 is bridged onto the upper crossbeam 5 and the lower crossbeam 2, and the controller 9 is connected to the fixing plate 3. To adapt to the spatial position within the frame 1, the fixing plate 3 is tilted as a whole due to the shape and fixing position of the upper crossbeam 5 and the lower crossbeam 2. The controller 9 is also tilted after being mounted on the fixing plate 3, adapting to the spatial position of the fixing plate 3. A window 31 is provided in the middle of the fixing plate 3, and several strip-shaped openings 32 are provided on the outside of the window 31 on the fixing plate 3. Through the window 31 and the openings 32, the controller 9 can exchange heat with the outside environment.
[0022] Figure 1 As shown, two connecting pieces 4 are welded and fixed to the lower end of the lower crossbeam 2. An L-shaped plate-like mounting base 6 is provided at the lower end of the mounting frame. The mounting base 6 is fixed to the connecting pieces 4 by bolts. The fan 7 is installed in the mounting base 6. The fan 7 is fitted and fixed to the mounting base 6. Several through-holes 61 are provided on the mounting base 6 corresponding to the position of the fan 7. These air holes 61 are arranged in groups, and a group of air holes 61 corresponds to the setting position of one fan 7, thereby forming a stable airflow in the fan 7.
