Description

Technical Field

[0001] This utility model relates to the field of temperature control equipment technology, and in particular to a modularly combinable temperature controller. Background Technology

[0002] As a core control component in industrial automation, smart buildings, and HVAC, thermostats are increasingly widely used. With the increasing complexity of application scenarios and the diversification of user needs, traditional single-function thermostats can no longer meet all requirements. For example, some applications require additional temperature control loops, while others may require the integration of specific humidity or pressure sensing functions.

[0003] To address this challenge, some thermostats with expansion interfaces have emerged on the market, allowing for performance enhancement through external functional modules. However, existing technologies often have shortcomings in their physical connection methods when implementing such modular combinations. Some solutions rely on multiple bolts for fixing, making module installation and removal cumbersome, requiring specialized tools, and time-consuming, making them unsuitable for applications requiring rapid adjustments or maintenance.

[0004] Other solutions employ simple snap-fit ​​structures for quick installation, but the stability of such connections is often lacking, especially in industrial environments with mechanical vibrations. Loosening at the joints can easily occur, affecting not only the normal operation of the expansion module but also potentially threatening the stability and safety of the entire temperature control system. Therefore, there is an urgent need for a modular assembly structure that allows for both quick assembly and disassembly while ensuring a stable and reliable connection.

[0005] Therefore, this utility model proposes a modularly combinable temperature controller to address the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems existing in the technology of thermostats when modular combination, such as cumbersome and time-consuming physical connection structure or insufficient connection stability that is easy to loosen, this utility model aims to provide a modular thermostat with improved structure that can effectively solve the above problems.

[0007] This utility model provides a modularly combinable temperature controller, including a main body, modular expansion devices, and a sliding plate.

[0008] A sliding groove and a snap-fit ​​groove are provided on one side of the main body of the equipment. A connecting plate is fixedly connected to the modular expansion equipment.

[0009] The connecting plate is designed to be pluggably fitted into the snap-fit ​​groove for positioning. The sliding plate is slidably installed in the sliding groove. When the connecting plate is inserted into the snap-fit ​​groove, the sliding plate can slide along the length of the sliding groove to limit the modular expansion device, thereby locking the modular expansion device.

[0010] Preferably, to achieve electrical connection between the main body of the equipment and the modular expansion device, a data transmission port is provided on the mating surface of the main body of the equipment and the modular expansion device. The data transmission port includes a first interface and a second interface that are electrically connected to each other. The first interface is fixed to the main body of the equipment, and the second interface is fixed to the modular expansion device. When the modular expansion device is installed in place, the first interface and the second interface are also connected simultaneously to achieve reliable transmission of data and signals.

[0011] Preferably, the snap-fit ​​slot is located below the sliding slot. This top-bottom layout makes the installation process more logical. The operator can first use the lower snap-fit ​​slot as a reference for insertion and positioning, and then operate the upper sliding plate to lock it in place. The process is clear and less prone to errors.

[0012] Preferably, the connecting plate has a wedge-shaped cross-section. This wedge-shaped structure plays a role in automatic centering and guidance during the insertion of the connecting plate into the snap-fit ​​groove, reducing the difficulty of installation alignment and making the assembly process smoother.

[0013] Preferably, the main body of the device also includes a data expansion port and a connection port. These two ports serve as interfaces for the temperature controller to interact with a wider range of external systems, allowing it to connect to additional sensors, actuators, or be integrated into a factory automation network, thus enhancing the device's system integration capabilities.

[0014] Preferably, the front panel of the main body of the equipment is equipped with a temperature control screen and a control terminal. The temperature control screen is used to intuitively display information such as temperature, set value, and equipment status, while the control terminal provides a human-machine interface to facilitate users in setting parameters and operating the equipment, thus forming a complete basic control and display unit.

[0015] Preferably, in order to ensure the stable operation of the internal electronic components, the outer casing of the main body of the equipment is provided with heat dissipation holes. The heat dissipation holes help to dissipate the heat generated during the operation of the equipment to the external environment in a timely manner, avoid performance degradation or damage due to overheating, and improve the long-term operational reliability of the equipment.

[0016] Preferably, the temperature controller also includes bolts, which are inserted into the main body of the equipment to fasten the outer shell, internal circuit board and other structural components of the main body of the equipment, ensuring that the entire equipment has excellent structural rigidity and vibration resistance.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problem of limited functionality and difficulty in expansion of existing temperature controllers by setting a snap-fit ​​groove and a sliding groove on the main body of the device, and cooperating with the connecting plate and a sliding plate on the modular expansion device. Users can quickly and conveniently combine or replace functional modules according to actual needs, which enhances the applicability and flexibility of the device and reduces the cost of upgrading the device.

[0019] 2. This utility model uses a combined connection structure that positions the device by inserting a connecting plate into a snap-fit ​​slot and then uses a sliding plate for sliding locking. This solves the problem of unstable connection and easy loosening that may result from simple plug-in connection of modular equipment. The mechanical connection structure is stable and reliable, can effectively resist external vibration interference, and ensures the overall stable operation of the equipment.

[0020] 3. This utility model solves the problem that traditional temperature controllers, as independent units, are difficult to integrate into large-scale automated control systems by setting a data transmission port between the main body of the equipment and the modular expansion equipment, as well as a data expansion terminal for connecting to external systems. It achieves the technical effect of not only realizing data interaction between internal modules, but also facilitating communication with external devices and systems, thereby improving the system integration capability and overall intelligence level of the equipment.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please refer to Figures 1 to 4 This utility model provides a modular thermostat, which aims to solve the problems of fixed functions, poor expandability, and difficulty in adapting to changing working conditions in the existing thermostat.

[0029] like Figure 1 and Figure 2 As shown, the modular thermostat includes a main body 1 and a modular expansion device 8 that is detachably combined with the main body 1. The main body 1 serves as the core carrier of the entire temperature control system, providing installation and operating space for various internal components. The modular expansion device 8 is used to expand the thermostat's functions as needed. A temperature control screen 3 and a control terminal 5 are provided on the front panel of the main body 1. The temperature control screen 3 is used to display temperature parameters and equipment status, and the control terminal 5 is used to input operation commands. Heat dissipation holes 2 are provided on the outer shell of the main body 1 to dissipate the heat generated inside the equipment. The main body 1 is also provided with a data expansion terminal 10 and a connection terminal 11. These two ports are used to connect the thermostat to external sensors or actuators and other devices. The thermostat also includes bolts 4, which are inserted into the main body 1 to reinforce the overall structure of the equipment.

[0030] To solve the above-mentioned technical problems, the core of the technical solution of this embodiment is that the temperature controller also includes a sliding plate 6, and the sliding plate 6 forms a specific structural cooperation and connection relationship with the aforementioned device body 1 and modular expansion device 8.

[0031] Please refer to the following carefully. Figure 1 , Figure 3 and Figure 4 The core structure will be described in detail below:

[0032] The inner wall of the main body 1 of the device has a sliding groove 7 for guiding and accommodating the sliding plate 6, and a snap-fit ​​groove 9 for positioning the modular expansion device 8 is provided below the sliding groove 7. The sliding plate 6 is slidably connected in the sliding groove 7. At the same time, the modular expansion device 8 is provided with a connecting plate 13 that is adapted to the shape and size of the snap-fit ​​groove 9. In the assembled state, the connecting plate 13 of the modular expansion device 8 is first inserted into the snap-fit ​​groove 9 of the main body 1 to achieve initial positioning. Then, the sliding plate 6 slides along the length of the sliding groove 7 to a predetermined position, thereby abutting and locking the modular expansion device 8 and preventing it from coming out of the snap-fit ​​groove 9. This matching structure of first inserting for positioning and then sliding for locking ensures the stability and reliability of the connection between the modular expansion device 8 and the main body 1, and at the same time realizes convenient and quick installation and disassembly. For the setting of the data transmission port 12 to ensure data interaction between the main body 1 and the modular expansion device 8, various conventional methods such as pins and contacts can be used.

[0033] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0034] As a preferred embodiment, please refer to Figure 4 In order to realize data communication between the main body 1 and the modular expansion device 8, a data transmission port 12 is provided on the joint surface of the main body 1 and the modular expansion device 8. The data transmission port 12 includes a first interface and a second interface that are electrically connected to each other. The first interface is fixed on the main body 1 and the second interface is fixed on the modular expansion device 8. When the modular expansion device 8 is installed in place, the first interface and the second interface are electrically connected.

[0035] As a preferred embodiment, please refer to Figure 4 To optimize the installation structure, the snap-fit ​​groove 9 is located below the sliding groove 7. This layout facilitates the modular expansion device 8 to first insert the connecting plate 13 into the snap-fit ​​groove 9 for positioning, and then the sliding plate 6 slides and locks.

[0036] As a preferred embodiment, please refer to Figure 3 In order to facilitate the insertion of the connecting plate 13 into the snap-fit ​​groove 9, the cross section of the connecting plate 13 is wedge-shaped. The wedge-shaped structure plays a guiding and alignment role during insertion.

[0037] As a preferred embodiment, please refer to Figure 1 and Figure 2 In order to enhance the external interaction capability of the temperature controller, the main body of the device 1 is also equipped with a data expansion terminal 10 and a connection terminal 11.

[0038] As a preferred embodiment, please refer to Figure 1 In order to achieve human-computer interaction, the front panel of the main body of the device 1 is equipped with a temperature control screen 3 and a control terminal 5.

[0039] As a preferred embodiment, please refer to Figure 1 and Figure 2 In order to ensure stable operation of the equipment, heat dissipation holes 2 are provided on the outer shell of the main body 1.

[0040] As a preferred embodiment, please refer to Figure 1 In order to improve the overall structural stability, the temperature controller also includes bolts 4, which are inserted into the main body 1 of the equipment and fasten all components.

[0041] The working principle of this modularly combinable temperature controller is as follows:

[0042] During modular assembly, the connecting plate 13 on the modular expansion device 8 is aligned with the snap-fit ​​groove 9 on the main body 1 and inserted. The wedge-shaped structure of the connecting plate 13 guides it smoothly into the snap-fit ​​groove 9 to achieve initial positioning. After positioning, the sliding plate 6 is pushed to slide along the sliding groove 7 until the sliding plate 6 is limited to the modular expansion device 8. This action prevents the connecting plate 13 from coming out of the snap-fit ​​groove 9, thus completing the stable installation of the modular expansion device 8 on the main body 1.

[0043] While the mechanical structure is installed, the data transmission port 12 located on the joint surface between the main body 1 and the modular expansion device 8, including the first interface and the second interface, is electrically connected to each other, ensuring that the data interaction between the main body 1 and the modular expansion device 8 is connected. When disassembling, simply slide the sliding plate 6 in the opposite direction to release the restriction on the modular expansion device 8, and the modular expansion device 8 can be pulled out from the buckle slot 9 to achieve quick separation.

[0044] When the equipment is running, the operator inputs operation commands through the control terminal 5 on the main body 1. The temperature control screen 3 displays real-time temperature parameters and operating status. The heat dissipation holes 2 on the outer shell of the main body 1 dissipate internal heat in a timely manner to ensure system stability. The data expansion terminal 10 and the connection terminal 11 are used to connect to external sensors, actuators or upper-level control systems. Through the above-mentioned mechanical combination structure of insertion positioning and sliding locking and the corresponding data interface, this utility model solves the technical problem of fixed function and difficulty in expansion of temperature controllers in the prior art.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
