Description

Technical Field

[0001] The invention relates to the technical field of motor housing protection, and in particular to a sealing structure of a motor housing of an electric tricycle. Background Art

[0002] An electric tricycle is a means of transportation that uses electric drive as its main power source. Its main uses include freight, short-distance travel and personal transportation. The electric motor is the main power source and can be a DC motor or an AC motor. The motor is selected according to different vehicle design and performance requirements, and stores electrical energy for use by the motor.

[0003] Electric vehicles usually operate in various weather conditions, including rainy days and humid environments. The motor is the main power source of the vehicle. Without a good sealed casing, rain or moisture may enter the motor and cause motor failure, short circuit or damage. In a dusty environment, a motor without a sealed casing is prone to inhaling dust and debris, which may clog the cooling fan or cooling holes, causing the motor to overheat or degrade in performance. The sealed casing can also serve as the outer protective shell of the motor to reduce the direct impact of external objects on the motor's mechanical structure and prevent mechanical damage and damage caused by collision.

[0004] However, the existing motor housing lacks a tight sealing structure, and rainwater still seeps in. While ensuring good sealing and waterproof performance, it is often accompanied by a complex sealing structure, which will lead to a large amount of disassembly work during maintenance and repair, increasing maintenance costs and time costs. The extreme sealing may also affect the normal heat dissipation of the motor, so the design of the motor housing needs to find a balance between waterproof performance and heat dissipation and ventilation. Therefore, the present invention proposes a sealing structure for the motor housing of an electric tricycle to solve the problems mentioned in the above background technology.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The hexahedral sealing structure of the motor provided by the present invention is composed of three parts: a sealing group, a fixing group and a side group. The sealing seat and the fixing seat constitute the upper and lower sides and the front and rear sides of the sealing shell, and the side panels on both sides constitute the left and right sides of the sealing shell. The fixing seat, the side panels on both sides and the edge joints of the sealing seat are all provided with corresponding sealing strips.

The wind drum is rotated and opened only when the airflow is exchanged, so as to prevent the outside from entering the shell through the screen holes for a long time, which is easy to cause the inside of the shell to be damp on rainy days. In addition, the airflow exchange structure realizes the exchange of airflow inside and outside the shell without affecting the sealing effect of the shell, thereby ensuring the normal heat dissipation of the motor.

[0023] 3. The side plate structure provided in the present invention is not only a component of the sealed shell, but also serves as a transfer station for the air outlet channel. The valve plate structure can prohibit the air from flowing back. The outer side has a plurality of air outlet structures, the inner diameter of the outlet is large and the outer diameter is small, and the outer hole is lower than the inner control, which is convenient for air to flow out and inconvenient for external water vapor to enter the inside of the side plate. The provided sealing seat structure is not only a component of the sealed shell, but also serves as an air inlet channel for airflow exchange. The water tank structure provided above and below the channel can accumulate water vapor and discharge it, realizing the drainage function inside the sealed shell;

[0024] In summary, the casing sealing structure of the present application not only provides effective external protection for the internal motor, but also facilitates disassembly and maintenance. While taking into account the airflow exchange inside and outside the casing, the overall relative sealing of the casing is achieved. The inside of the casing also has a drainage design structure, and multiple protections avoid the impact of humid environment on the motor. BRIEF DESCRIPTION OF THE DRAWINGS
