Description

Technical Field

[0001] This utility model relates to an external controller for a DC tubular motor. Background Technology

[0002] The widespread use of tubular DC motors in electric doors and windows provides more energy-efficient and quieter motor power solutions for these devices. The tubular DC motor controllers used in these two fields primarily employ the following configuration methods.

[0003] External power input, with an additional one-button rocker switch. Currently, the only external power supply available for DC motors is an external regulated power supply, but its structural dimensions make it difficult to integrate with the actual installation environment of electric doors and windows. External regulated power supplies are also limited by the installation environment and pose safety hazards to a certain extent; they also account for a significant portion of the overall cost of doors and windows.

[0004] It uses an external lead-acid battery and an additional control module. Due to size limitations, it can only be used on electric roller shutters. It cannot meet the basic aesthetic requirements for interior shading applications.

[0005] The DC tubular motor has a built-in lithium battery. This built-in design offers advantages such as good concealment and a high aesthetic appeal to end users. However, precisely because the battery is completely built into the motor, and the tubular motor is installed entirely within the door or window roller tube, charging difficulties, high failure rates, and high maintenance costs become its biggest drawbacks, especially given the inconvenience of disassembly and reassembly. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide an external controller for a DC tubular motor that is compact, convenient for battery charging or replacement, and easy to maintain, in contrast to the above-mentioned prior art.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an external controller for a DC tubular motor, including a base, a housing detachably mounted on the base, a control circuit board and a battery pack mounted inside the housing, and buttons mounted on the housing. The control circuit board is provided with a wireless communication module, and the battery pack and buttons are electrically connected to the control circuit board.

[0008] The base is provided with a first electrical connection module for electrically connecting to a DC tubular motor, and the housing is provided with a second electrical connection module that matches and connects to the first electrical connection module. The second electrical connection module is electrically connected to the control circuit board.

[0009] To effectively ensure the high current carrying capacity of the motor under load, the first electrical connection module and the second electrical connection module are matched and connected four-core brass plugs and four-core brass sockets.

[0010] Preferably, the button is embedded in the housing.

[0011] To ensure that the control circuit board is not affected or damaged during the stall process of the DC tubular motor, a fuse connected to the power distribution of the control circuit board is also included.

[0012] For easy replacement and installation, the housing is provided with an outwardly open limiting socket, into which the safety plate is inserted for power connection with the control circuit board.

[0013] To ensure reliable installation of the housing on the base, the base has a slot into which the housing is fitted and inserted.

[0014] In order to ensure that the housing is inserted into the base and thus ensure the reliable docking of the first electrical connection module and the second electrical connection module, at least one side of the housing is provided with a stepped portion that matches and abuts against the edge of the slot.

[0015] Preferably, the extension lines of the stepped portion are curved.

[0016] Preferably, the first electrical connection module is disposed at the bottom of the slot, and the second electrical connection module is disposed on the end face of the housing insertion end.

[0017] To enhance the aesthetics of the external controller for the DC tubular motor and create a subtle light diffusion effect during use, the control circuit board is equipped with LED lights, and a light guide column is placed on the LED lights inside the housing. The light guide column is surrounded by a light-shielding layer.

[0018] Compared with the prior art, the advantages of this utility model are as follows: The external controller for the DC tubular motor in this utility model, through the detachable connection between the base and the housing, facilitates the removal of the housing and its internal components from the base, making it particularly convenient for replacing or charging the battery inside the housing. Because of this ease of battery replacement or charging, the battery size requirement can be reduced, thereby reducing the battery's volume and making the overall size of the external controller more compact, meeting aesthetic requirements.

[0019] In addition, when the external controller malfunctions and needs repair, it can be removed from the base via the housing, which facilitates the repair of the internal components and enables independent maintenance of the external controller, resulting in lower maintenance costs.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] The external controller for the DC tubular motor in this embodiment can be applied to products such as electric doors and windows. These products incorporate DC tubular motors, and the opening and closing of the electric doors and windows is achieved by driving the DC tubular motors. The external controller for the DC tubular motor in this embodiment is used to implement the drive control of the DC tubular motor.

[0029] like Figures 1 to 7 As shown, the external controller for the DC tubular motor in this embodiment includes a base 1, a housing 2, a control circuit board 3, a battery pack 4, and a button 5. The control circuit board 3 and the battery pack 4 are disposed inside the housing 2, and the button 5 is embedded in the housing 2 for easy pressing operation. The battery pack 4 and the button 5 are both electrically connected to the control circuit board 3.

[0030] The base 1 and housing 2 are connected in a detachable manner. To ensure the reliability of the housing 2's installation on the base 1, the base 1 has a slot 11, meaning the base 1 adopts a slot structure, and the housing 2 is inserted into the slot 11. In use, the base 1 is fixedly connected to the end of the door, window, or other application product. The base 1 is equipped with a first electrical connection module 6 for electrically connecting to a DC tubular motor, while the housing 2 has an exposed second electrical connection module 7 that matches and mates with the first electrical connection module 6. The second electrical connection module 7 is electrically connected to the control circuit board 3. When the housing 2 is inserted into the slot 11 of the base 1, the second electrical connection module 7 can mate with the first electrical connection module 6, thereby realizing the electrical signal connection between the motor and the control circuit board 3.

[0031] In this embodiment, the first electrical connection module 6 and the second electrical connection module 7 are made of matched four-core brass contacts and four-core brass sockets. The four-core brass contacts and four-core brass sockets have the characteristics of low impedance and strong overcurrent capability, which effectively ensures the high current carrying capacity of the motor under load.

[0032] Based on the plug-in structure of the housing 2 and the base 1, in order to ensure that the first electrical connection module 6 and the second electrical connection module 7 are connected based on the insertion direction of the housing 2 relative to the base 1, in this embodiment, the first electrical connection module 6 is set at the bottom of the slot 11, and the second electrical connection module 7 is set on the end face of the insertion end of the housing 2.

[0033] To prevent the housing 2 from not being properly inserted into the base 1, which could lead to misalignment of the first electrical connection module 6 and the second electrical connection module 7, at least one side of the housing 2 is provided with a stepped portion 22 that matches and abuts against the edge of the slot 11. Thus, when the housing 2 is inserted into the slot 11, if the stepped portion 22 abuts against the edge of the slot 11 and cannot penetrate further, it indicates that the housing 2 is properly inserted into the base 1, and the first electrical connection module 6 and the second electrical connection module 7 are reliably connected. In this embodiment, the extended line of the stepped portion 22 is curved. This curve can be a wide wavy line, a sawtooth line, etc. The edge of the slot 11 on the base 1 is an extension line that matches the extended line of the stepped portion 22, thereby achieving precise alignment. This ensures proper insertion while preventing misalignment that could lead to misalignment of the first electrical connection module 6 and the second electrical connection module 7.

[0034] In addition, the housing 2 in this embodiment consists of two half-shells that can be fitted together, which facilitates the installation of components inside the housing 2 and the maintenance of components inside the housing 2.

[0035] The control circuit board 3 is equipped with a wireless communication module, which enables wireless communication connection with an external remote control or an external smart terminal, thereby facilitating remote control of the external controller. At the same time, the input signal based on button 5 can also control the start and stop of the wireless communication module.

[0036] Battery pack 4 can be selected from existing batteries as needed. In this embodiment, multiple 18650 lithium batteries are used as battery pack 4 for energy storage, thus storing more energy in a very small space. While ensuring sufficient energy storage, a compact body design is also achieved, which facilitates the aesthetic installation of this external controller and meets the aesthetic requirements for indoor installation.

[0037] When a DC tubular motor operates in a product, it has a large instantaneous current requirement during the startup phase. Additionally, when roller shutters and windows are constrained by external conditions, the DC tubular motor may stall, also resulting in a large current. To ensure that the control circuit board 3 is not affected or damaged under high current conditions, the external controller for the DC tubular motor in this embodiment also includes a fuse 8 that is plugged into the control circuit board 3 for power distribution. Under high current conditions, the automotive-grade fuse 8 effectively self-melts, ensuring that the controller's internal components are not affected or damaged. Due to the operating characteristics of the fuse 8, it needs to be replaced. In this embodiment, the housing 2 is provided with an outwardly open limiting socket 21. The fuse 8 is inserted into the socket and plugged into the control circuit board 3 for power distribution. This structure facilitates the replacement and installation of the fuse 8.

[0038] To enhance the aesthetics of the external controller for the DC tubular motor and create a subtle light diffusion effect during use, the control circuit board 3 is equipped with LED lights 9. Inside the housing 2, a light guide post 91 is positioned above the LED lights 9, and a light-shielding layer is wrapped around the light guide post 91. The button 5 typically comprises an elastically deformable rubber structure, which is prone to damage with prolonged pressing. To protect the rubber structure, a protective shell is placed on top of it, embedded in the housing 2. The corresponding rubber structure can be located within the housing 2. Since rubber has good deformability and encapsulation properties, in this embodiment, the light guide post 91 is placed within the rubber structure of the button 5, using the rubber structure of the button 5 as a light-shielding layer. Only the tip of the light guide post 91 emits light, achieving a visually complete yet subtly diffused light effect on the upper shell of the housing 2, resulting in a more aesthetically pleasing appearance.

[0039] The external controller for the DC tubular motor in this invention features a detachable connection between the base 1 and the housing 2, facilitating the removal of the housing 2 and its internal components from the base 1. This makes it particularly convenient to replace or charge the battery inside the housing 2. Because of this ease of battery replacement and charging, the battery size requirement can be reduced, resulting in a smaller overall size for the external controller and meeting aesthetic requirements.

[0040] In addition, when the external controller malfunctions and needs repair, it can be removed from the base 1 via the housing 2, which facilitates the repair of the internal components of the housing 2, enabling independent maintenance of the external controller and reducing maintenance costs.

[0041] In the specification and claims of this utility model, terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of this utility model. However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
