Description

Technical Field

[0001] The utility model relates to the field of electronic technology, in particular to an electronic device. Background Art

[0002] Some existing electronic devices are provided with a USB / TYPE-C interface to realize charging or communication of internally powered lithium batteries. Common electronic devices of this type, such as motors for driving curtains, are provided with a USB / TYPE-C interface. For example, a DC electronic limit motor with high limit accuracy and good silent effect disclosed in a Chinese patent with application number 201520919634.7 includes a power supply part, a control part, and a motor drive part. The motor drive part includes a reducer and a DC motor, and the motor is provided with a USB charging port at the front end near the reducer; another example is a tubular motor external communication module disclosed in a Chinese patent with application number 202122712284.5, including: a tubular motor, a USB interface installed on the surface of the tubular motor; an electronic component assembly, including a main board and a USB plug fixed at the end of the main board, and the USB plug is plugged into the USB interface on the surface of the tubular motor; another example is an electric curtain opening and closing motor disclosed in a Chinese patent with application number 202122418902.5, including a motor housing, an upper cover, an output shaft, a clutch, a clutch mounting sleeve, a reducer, a motor assembly, a lithium battery, a lithium battery fixing frame, a control circuit board, a circuit board protective cover and a lower cover, and the lower cover is provided with a Type-C charging interface connected to the lithium battery.

[0003] Since these products often have long-term storage, transportation, and transit, the electronic control system inside will consume the stored power continuously or intermittently. The problem may not be obvious in a short time, but if it lasts for a long time, the battery will be depleted, and even the end customer will find that the battery is too low or exhausted after receiving the finished product.

[0004] To solve this problem, the current existing solutions are: 1) a toggle switch is provided on the annular PCB board of the motor travel head to achieve mode switching, but the travel head itself is too small to be placed in it, or the PCB board space is narrow, the welding processing cost is high, and the toggle switch needs to be slotted at the end cover, which affects the sealing of the product; 2) using the built-in setting key to enter the low-power transportation mode by long pressing, but it will be found that a few of them do not enter the low-power transportation mode due to manual operation omissions when they are shipped in batches, so it is necessary to cooperate with the indicator light to intuitively display whether to switch the mode in the subsequent check, which increases cost and manpower. For this reason, further improvement is needed. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide an electronic device that is convenient for entering a low power consumption mode and can display intuitively while ensuring waterproof and dustproof performance in view of the deficiencies in the above-mentioned prior art.

[0006] The technical solution adopted by the utility model to solve the above technical problems is: an electronic device, including an MCU module and an interface, wherein the interface is a USB or TYPE-C interface, characterized in that:

[0007] The electronic device further comprises an external electronic switch device, a first connection socket is arranged in the interface, a second connection socket is arranged in the electronic switch device, and the first connection socket and the second connection socket are male and female matching sockets;

[0009] When the electronic switch device is not matched with the interface, the pin of the first connector electrically connected to the MCU module is at a first potential;

[0010] When the electronic switch device is plugged into the interface, the pin of the first connector electrically connected to the MCU module changes to a second potential, thereby the MCU module enters a low power consumption mode.

[0011] By using an external electronic switch device, it is avoided to open a hole to set a toggle switch, and the dustproof and waterproof effects are achieved. There is no need to set keys and indicator lights for switching, which is easy to operate and intuitive. When it is inserted into the interface, the MCU module can receive the potential change signal, that is, enter the low power mode, and the current drops significantly, avoiding the situation of long-term sea transportation causing lithium battery depletion and damage to the lithium battery. Moreover, this electronic switch device can also be recycled and reused after transportation, thereby reducing costs.

[0012] Furthermore, since electronic devices usually only use the charging function, the communication pin of the connector can be utilized. The second connector includes a communication pin that maintains a second potential, and the pin of the first connector corresponding to the communication pin is electrically connected to the I / O port of the MCU module.

[0013] Furthermore, the second connector also includes a ground pin, and the communication pin is connected to the ground pin, so that it can be achieved by connecting the two pins without setting other components of the device. The structure is simple and easy to operate.

[0014] Preferably, the first connector and the second connector are both TYPE-C sockets.

[0015] According to one aspect of the utility model, the method of reducing power consumption is that the electronic device also includes a wireless module controlled by the MCU module to enter a low power consumption mode.

[0016] According to another aspect of the utility model, the method for reducing power consumption is that the electronic device also includes a wireless module, and the MCU module controls the power on and off of the wireless module through the switch tube Q.

[0017] Preferably, the wireless module is a ZIGBEE module and / or an RF module.

[0018] Preferably, the electronic device is a motor.

[0019] Compared with the prior art, the utility model has the advantages that: by adopting an external electronic switch device, it avoids opening a hole to set a toggle switch, achieves dustproof and waterproof effects, and does not need to set keys and indicator lights for switching, which is easy to operate and intuitive. When it is inserted into the interface, the MCU module can receive a potential change signal, that is, enter a low power consumption mode, and the current drops significantly, avoiding long-term sea transportation and other situations that cause lithium battery depletion and damage to the lithium battery. Moreover, this electronic switch device can also be recycled and reused after transportation, thereby reducing costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] In the description of the present utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Since the embodiments disclosed in the present utility model can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0028] See also Figures 1 to 4 , an electronic device includes an MCU module 1, a ZIGBEE module 2, an RF module 3 and an interface 4, wherein the interface 4 is a USB or TYPE-C interface. The ZIGBEE module 2 and the RF module 3 are both wireless modules, and the electronic device may include any one or two of them, wherein the ZIGBEE module 2 is used to connect to a smart host, and may also be a WIFI module or a Bluetooth module, and the RF module 3 is a wireless signal receiving module. In this embodiment, the electronic device is taken as an example of a motor, and the interface 4 may be set at the end cover 100 of the motor. It may also be any electronic device including the above modules.

[0029] Among them, the MCU module 1 is electrically connected to the ZIGBEE module 2 and the RF module 3 respectively, wherein the ZIGBEE module 2 is connected to the power supply output terminal of the lithium battery (not shown) through the switch tube Q, and the MCU module 1 controls the on and off of the switch tube Q, and the switch tube Q is a component that can be used as a switch, such as a triode, a diode, a MOS tube, etc. In this embodiment, the switch tube Q is a PMOS tube, the ZIGBEE module 2 is connected to the drain of the PMOS tube, the MCU module 1 is connected to the gate of the PMOS tube, and the source of the PMOS tube is connected to the power supply output terminal of the lithium battery. The MCU module 1 issues an instruction (high level, low level), thereby controlling the on and off of the switch tube Q, thereby controlling the on and off of the power supply of the ZIGBEE module 2.

[0030] The power supply circuit of the RF module 3 is similar to this.

[0031] The control device of the motor also includes an electronic switch device 5, which is an electronic switch device (mini type). A first connector 41 is provided in the interface 4, and a second connector 51 is provided in the electronic switch device 5. The first connector 41 and the second connector 51 are male and female sockets. For example, the first connector 41 can be a female socket, and the second connector 51 can be a male socket. When the second connector 51 is plugged into the first connector 41, the output level of the first connector 41 changes. After receiving the change information, the MCU module 1 outputs a control instruction to disconnect the switch tube Q and control the power supply of the ZIGBEE module 2 to be disconnected.

[0032] The above seat is explained using TYPE-C seat as an example, see Figure 5 and Figure 6 The pins of the TYPE-C male and female sockets include power supply pins, ground pins, and communication pins (there are multiple pins with different definitions). Since they are usually used for driving motors such as curtains, the interface usually only needs charging. Therefore, the idle communication pins - A8 and B8 pins (symmetrical, with the same functions for forward and reverse insertion) are connected to the ground pins - A1, B1, A12, and B12 pins to keep them at a low potential.

[0033] When the electronic switch 5 is not inserted into the interface 4, the I / O port of the MCU module 1 (the MCU module 1 has multiple I / O ports, and the functions can be customized) is electrically connected to at least one communication pin of the interface 4 (such as the pin corresponding to the A8 and B8 pins of the second connector 5), and the corresponding pin of the interface 4 is in a high position (first potential). When the electronic switch device 5 is inserted into the interface 4, the I / O pin of the MCU module 1 corresponding to the A8 and B8 pins receives a signal that changes to the second potential (low potential), so that it enters a low power consumption mode, and sends a control signal to the ZIGBEE module 2 and the RF module 3 to enter the low power consumption mode, or controls the power supply of each module through the switch tube Q switch to achieve low power consumption. After entering the low power consumption mode, the power consumption inside the motor is reduced to 20-30uA, which is about one-third of the power consumption of 80-100uA in the normal standby state (the wireless module is still working in standby). Therefore, when the motor needs to be stored, transported, transferred, etc., it avoids the lithium battery being depleted due to long-term sea transportation and damage to the motor lithium battery. At the same time, in this mode, all possible electronic device wake-up actions are prohibited, forming an anti-foolproof design.

[0034] When the user needs to use the electronic device normally or use USB / TYPE-C for charging / communication, or exit the storage and transportation mode, the user only needs to move out the electronic switch device 5, which is convenient and quick, and the product function is immediately in normal working state.

[0035] This method is not only convenient and fast, but also can be displayed intuitively. It can be universally used on other electronic devices and is easy to promote.
