Technical Field
[0001] This utility model belongs to the technical field of transmission box equipment, specifically relating to a transmission box bottom shell connection structure with replaceable modules. Background Technology
[0002] With the booming development of the smart home market, curtain motor drive boxes, with their function of automatically controlling the opening and closing of curtains, have gradually become key equipment in modern smart home scenarios. The control module, as the core of the curtain motor drive box, is responsible for core functions such as signal reception, command parsing, and motor drive. Its performance directly determines the operational stability and user experience of the automated curtain system. However, existing control modules mostly adopt a highly integrated design, tightly embedded inside the drive box, entangled with other circuits and wiring. Furthermore, replacing the control module requires removing the drive box casing, resulting in low replacement efficiency.
[0003] To address the shortcomings of existing technologies, people have conducted long-term explorations and proposed various solutions. For example, Chinese patent literature discloses a curtain motor with an easily replaceable control module [202420762857.6], which includes a motor body, a control module, and a touch-type electrical connection component. The outer wall of the motor body has a mounting slot, and the control module is detachably embedded in the mounting slot, enabling a touch-type electrical connection between the control module and the motor body. The control module is a network control module and / or a voice control module.
[0004] The above solution addresses the problem of low replacement efficiency of existing control modules to some extent, but it still has many shortcomings. For example, the control module is directly mounted on the outside and is easily contaminated by the outside environment, resulting in a shorter lifespan of the control module and increased user costs. Summary of the Invention
[0005] The purpose of this utility model is to address the above-mentioned problems by providing a transmission box bottom shell connection structure with replaceable modules.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A replaceable module transmission box bottom shell connection structure includes a transmission box body with an internal control circuit board. One side of the transmission box body has a mounting groove. A bottom shell cover plate, capable of closing the mounting groove, is installed at the mounting groove via a detachable fixing mechanism. A replaceable control module is mounted on the side of the bottom shell cover plate near the mounting groove via a module mounting mechanism. The bottom of the mounting groove has a module mounting cavity for accommodating the replaceable control module when the bottom shell cover plate is installed in the mounting groove. The module mounting cavity has several contacts connected to the control circuit board and capable of communicating with the replaceable control module when the bottom shell cover plate is installed in the mounting groove. One side of the replaceable control module can contact and connect with the contacts via a contact point, facilitating the transmission of control signals from the replaceable control module to the control circuit board. The detachable fixing mechanism allows for quick disassembly of the bottom shell cover plate, improving disassembly efficiency. The bottom shell cover plate also provides protection for the replaceable control module. The module mounting mechanism facilitates the positioning and installation of the replaceable module, improving the loading and unloading efficiency of the replaceable module.
[0007] In the aforementioned replaceable module transmission box bottom shell connection structure, the width of the mounting groove is equal to the width of the bottom shell cover plate, and the length of the mounting groove is greater than the length of the bottom shell cover plate. This allows the bottom shell cover plate to be slidably mounted on the mounting groove, facilitating sliding installation of the bottom shell cover plate and improving installation efficiency.
