[0002] In modern sewing machines, the Electronic Control Unit (ECU) plays a vital role, controlling various functions of the sewing machine, including the up and down movement of the needle, the shuttling of the thread, speed adjustment, and various other complex sewing modes. Therefore, it is particularly important to protect this key component from external damage, such as dust, oil, moisture, and mechanical damage.

[0003] The existing electric control protection cover of sewing machines is usually a sturdy and sealed shell installed around the electronic control module of the machine. The material used in the shell can resist dust and moisture. However, in actual applications, it is found that while the electric control protection cover of many sewing machines provides protection for the electronic control module, the electric control buttons and display screens often lack effective protection measures. This means that although the ECU itself is well protected, during user operation, the unprotected state of the buttons and display screen may still cause misoperation, or even damage the equipment due to physical impact.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.
