Description

Technical fields:

[0001] This utility model belongs to the field of electric vehicle technology, and specifically refers to a heat dissipation and air cooling mechanism for electric vehicles. Background technology:

[0002] The electric vehicle disclosed in the existing Chinese utility model patent (authorization announcement number CN201872892U) includes a frame, a seat, wheels, and a battery pack. A charger is housed within a casing beneath the seat, and a controller and a motor are also housed within the casing. The motor is connected to the rear wheel via a belt. Ventilation slits are located on the sides of the casing, and a cooling fan is installed within the casing at the corresponding positions of the slits. This cooling fan provides air cooling to the controller, keeping its temperature within a certain range and preventing rapid aging and performance limitations of electronic components under prolonged high temperatures, thus effectively protecting its lifespan.

[0003] However, the above structure has the following problems: First, the built-in fan increases the material cost of the whole vehicle, and additional wiring harnesses and layout are required to install the built-in fan; Second, the operation of the built-in fan consumes the electric vehicle battery's power, affecting the electric vehicle's effective range; Third, the built-in fan will inevitably generate noise when it is running, affecting the riding experience. Summary of the Invention:

[0004] The purpose of this invention is to provide a heat dissipation and air cooling mechanism for electric vehicles. It abandons the existing built-in fan design and uses a front air vent and a rear air vent to allow external airflow to enter the electrical cavity to dissipate heat from the electric vehicle control assembly during driving. This effectively reduces the overall vehicle cost, does not affect the driving range, and reduces driving noise.

[0005] This utility model is implemented as follows:

[0006] A heat dissipation and air cooling mechanism for an electric vehicle includes an electric vehicle seat bucket and an electric vehicle seat shell fitted outside the electric vehicle seat bucket. An electrical cavity is formed between the electric vehicle seat bucket and the electric vehicle seat shell. An electric vehicle control assembly is installed inside the electrical cavity. A front air vent communicating with the electrical cavity is opened on the front side wall of the electric vehicle seat shell, and a rear air outlet communicating with the electrical cavity is opened on the rear side wall of the electric vehicle seat shell. An air cooling channel is formed between the front air vent, the electrical cavity, and the rear air outlet, allowing external airflow to flow through the electrical cavity.

[0007] In the above-mentioned heat dissipation and air cooling mechanism for an electric vehicle, the electric vehicle control assembly is provided with a radiator, which has heat dissipation fins that can contact the flowing airflow.

[0008] In the aforementioned heat dissipation and cooling mechanism for an electric vehicle, two sets of front air inlets and rear air outlets are provided and symmetrically distributed on the left and right sides of the electric vehicle seat shell.

[0009] In the aforementioned heat dissipation and air cooling mechanism for an electric vehicle, the port of the front air vent has a V-shaped structure with the opening facing the rear of the vehicle.

[0010] In the above-mentioned heat dissipation and air cooling mechanism of an electric vehicle, an air guide baffle is provided on the electric vehicle seat shell located outside the rear air outlet. The rear end of the air guide baffle is used to install the vehicle license plate. An air guide channel is formed between the air guide baffle and the electric vehicle seat shell, with the inner end communicating with the rear air outlet and the outer end facing downward.

[0011] In the above-mentioned heat dissipation and air cooling mechanism for an electric vehicle, the upper end of the air guide baffle is fixed to the electric vehicle seat shell, and the lower end of the air guide baffle is a free end and is inclined away from the electric vehicle seat shell.

[0012] The outstanding advantages of this utility model compared to the prior art are:

[0013] This utility model has a simple structure and reasonable design. It abandons the existing built-in fan design and uses the front air inlet and rear air outlet to allow external airflow to enter the electrical cavity to cool the electric vehicle control assembly during driving. This effectively reduces the overall vehicle cost, does not affect the driving range, and reduces driving noise. Attached image description:

[0018] The present invention will be further described below with reference to specific embodiments. See also: Figure 1 —3:

[0019] A heat dissipation and air cooling mechanism for an electric vehicle includes an electric vehicle seat bucket and an electric vehicle seat shell 1 fitted outside the electric vehicle seat bucket. An electrical cavity is formed between the electric vehicle seat bucket and the electric vehicle seat shell 1. An electric vehicle control assembly is installed inside the electrical cavity. A front air inlet 2 communicating with the electrical cavity is opened on the front side wall of the electric vehicle seat shell 1, and a rear air outlet 3 communicating with the electrical cavity is opened on the rear side wall of the electric vehicle seat shell 1. An air cooling channel is formed between the front air inlet 2, the electrical cavity, and the rear air outlet 3, allowing external airflow to flow through the electrical cavity.

[0020] This utility model has a simple structure and reasonable design. It abandons the existing built-in fan design and uses the front air inlet 2 and rear air outlet 3 to allow external airflow to enter the electrical cavity to cool the electric vehicle control assembly during driving. This effectively reduces the overall vehicle cost, does not affect the driving range, and reduces driving noise.

[0021] In order to effectively dissipate heat from the electric vehicle control assembly, a radiator is provided on the electric vehicle control assembly, and the radiator has heat dissipation fins that can come into contact with the flowing air.

[0022] In this embodiment, the electric vehicle control assembly is located in the middle of the rear side of the electric vehicle seat bucket and the electric vehicle seat shell 1, and near the rear air outlet 3. Therefore, in order to allow more external airflow to flow into the electrical cavity, the front air outlet 2 and the rear air outlet 3 are provided in two sets and symmetrically distributed on the left and right sides of the electric vehicle seat shell 1.

[0023] Furthermore, in this embodiment, the port of the front air vent 2 is a V-shaped structure with the opening facing the rear of the vehicle. At the same time, there are two front air vents 2 on the same side spaced apart along the front-rear direction.

[0024] Meanwhile, in order to disrupt the airflow at the rear air outlet 3, and considering that the electric vehicle control assembly is located close to the rear air outlet 3 to prevent external rainwater from directly entering the electrical cavity and affecting the electric vehicle control assembly, a wind deflector 4 is provided on the electric vehicle seat shell 1 located outside the rear air outlet 3. The rear end of the wind deflector 4 is used to install the vehicle license plate. The wind deflector 4 and the electric vehicle seat shell 1 form a wind channel with the inner end communicating with the rear air outlet 3 and the outer end facing downward. Furthermore, the upper end of the wind deflector 4 is fixed to the electric vehicle seat shell 1, and the lower end of the wind deflector 4 is a free end and is inclined away from the electric vehicle seat shell 1.

[0025] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
