[0027] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0028] Currently, chargers on the market primarily rely on electronic or software controls to reduce power consumption in standby mode. However, these methods still require electrical power, so standby power consumption cannot be completely eliminated. Furthermore, traditional electronic and software control methods pose a risk of electrical malfunction when the product is plugged in for extended periods, potentially leading to safety accidents such as explosions or fires. This device, through a mechanical linkage design between a gate valve switch and a rocker bridge, maintains a completely open circuit when no external device is inserted, thoroughly cutting off the power supply and achieving zero standby power consumption. Moreover, the contact slider allows adjustment of the conductive sheet's pressing force based on the insertion depth, ensuring low-contact connection terminals while preventing overvoltage damage.
[0029] like Figures 1 to 3 As shown, this embodiment provides a mechanical zero-standby charging device, including: a housing 100, a circuit board 200, and a conduction mechanism 300.
[0030] The following is a detailed description of the structure of the mechanical zero-standby charging device.
[0031] The housing 100 has an insertion port 110. The size of the insertion port 110 is adapted to standard charging plugs, such as USB plugs or Type-C plugs.
[0032] The circuit board 200 is disposed within the housing 100. Two connection terminals 210 are arranged side by side on the circuit board 200. The connection terminals 210 are configured to connect to an open circuit terminal of a circuit integrated in the circuit board 200. The two connection terminals 210 respectively form an open circuit connection with the integrated circuit in the circuit board 200, constituting a key node for electrical connection and disconnection.
[0033] In addition, the circuit board 200 is provided with a charging socket that is electrically connected to the integrated circuit, which is located on one side of the two connection terminals 210.
[0034] The conducting mechanism 300 includes a valve switch 310 and a rocker bridge 320. The valve switch 310 is movably disposed on one side of the insertion port 110. The valve switch 310 is provided with an abutting slider 311 at one end near the insertion port 110. The abutting slider 311 is configured to contact the external connector inserted into the insertion port 110. The rocker bridge 320 is rotatably disposed in the housing 100. One end of the rocker bridge 320 abuts against the valve switch 310. The other end of the rocker bridge 320 is provided with a conductive sheet 321 corresponding to two connection terminals 210. The other end of the rocker bridge 320 is configured to be able to contact the two connection terminals 210 synchronously.
[0035] The valve switch 310 can move up and down within the housing 100 under the drive of the external connector. The end of the valve switch 310 away from the abutting slider 311 is flat, thus ensuring that the valve switch 310 is in contact with the rocker bridge 320 during the standby phase.
[0036] The abutment slider 311 is a wedge-shaped component. This facilitates the sliding engagement of the external plug with the abutment slider 311, thereby pushing the valve switch 310 upward.
[0037] One end of the rocker bridge 320 is always in contact with the valve switch 310. The end of the rocker bridge 320 near the valve switch 310 is flat. This ensures that during standby, the rocker bridge 320 is in close contact with the valve switch 310, and facilitates subsequent rotation of the rocker bridge 320 under the influence of the valve switch 310. When the valve switch 310 is subjected to external force and moves upward, the rocker bridge 320 begins to rotate. The end of the rocker bridge 320 near the valve switch 310 faces upward, and the end near the connecting terminal 210 faces downward, thus bringing the end of the rocker bridge 320 near the connecting terminal 210 into contact with both connecting terminals 210.
[0038] When the mechanical zero-standby charging device of this embodiment is in operation, the device is plugged into an AC power source. When the external plug is not inserted, the gate valve switch 310 is in the initial position. At this time, the rocker bridge 320 is separated from the two connecting terminals 210, and the main circuit is in an open-circuit power-off state. When the external plug is fully inserted into the charging socket, it slides in conjunction with the abutment slider 311, causing the gate valve switch 310 to move upward, causing the rocker bridge to rotate. This causes the conductive sheet 321 of the rocker bridge 320 to press against the two connecting terminals 210 simultaneously, forming an electrical path, thereby activating the charging main circuit.
[0039] like Figures 1 to 3 As shown, in some embodiments, the abutment slider 311 is located in the insertion port 110. Thus, the abutment slider 311 can slide and engage with the charging plug when the charging plug enters the insertion port 110, thereby driving the door valve switch 310.
[0040] like Figures 1 to 3 As shown, in some embodiments, a guide assembly 120 is provided on the inner wall of the housing 100. The guide assembly 120 is located near the insertion port 110, and the valve switch 310 is movably disposed in the guide assembly 120. Thus, when the external plug drives the valve switch 310, the valve switch 310 can move linearly along the guide assembly 120, achieving smooth movement of the valve switch 310 and preventing the valve switch 310 from deviating.
[0041] like Figures 1 to 3 As shown, in some embodiments, the guide assembly 120 includes: a first guide block 121, a second guide block 122 and a pressure plate 123. The first guide block 121 and the second guide block 122 are symmetrically arranged on the inner wall of the housing 100. The pressure plate 123 is connected to the first guide block 121 and the second guide block 122 respectively. The pressure plate 123, the first guide block 121 and the second guide block 122 together form a guide space, and part of the valve switch 310 is located in the guide space.
[0042] The first guide block 121 and the second guide block 122 are integrally formed with the housing 100. Both the first guide block 121 and the second guide block 122 have a stepped structure, which can restrict part of the valve switch 310 between the first guide block 121 and the second guide block 122.
[0043] The pressure plate 123 is fixedly connected to the first guide block 121 and the second guide block 122 via connectors, forming a stable frame structure. This confines part of the valve switch 310 within the guide space, preventing the valve switch 310 from dislodging. Furthermore, under the combined action of the pressure plate 123, the first guide block 121, and the second guide block 122, the valve switch 310 receives uniform support and guidance during movement. This guiding action ensures smooth movement of the valve switch 310, preventing jamming or damage caused by shaking or deviation.
[0044] like Figures 1 to 3 As shown, in some embodiments, the inner wall of the housing 100 is provided with a stop rib 130, which is located on one side of the pressure plate 123; the conduction mechanism 300 includes a spring 330; the valve switch 310 is provided with a plug 312, one end of the spring 330 is sleeved on the plug 312, and the other end of the spring 330 abuts against the stop rib 130.
[0045] Spring 330 is located between stop rib 130 and insert 312. The elastic force of spring 330 provides timely power support when valve switch 310 needs to return to its position quickly, thereby improving the response speed and working efficiency of the entire device. The elastic buffering effect of spring 330 reduces the impact force on valve switch 310 during upward movement, reducing the risk of wear and damage, thus extending the service life of valve switch 310.
[0046] When the valve switch 310 moves upward, the spring 330 is compressed. At this time, the elastic force of the spring 330 will generate a reverse force on the valve switch 310, so that it remains stable during the upward movement and can quickly return to its original position when it moves downward.
[0047] When the valve switch 310 moves down, the spring 330 returns to its original position. At this time, the elastic force of the spring 330 will push the valve switch 310 back to its initial position.
[0048] like Figures 1 to 3 As shown, in some embodiments, the inner wall of the housing 100 is provided with a mounting post 140, and the rocker bridge 320 is threadedly connected to the mounting post 140. In this way, the rocker bridge 320 can be fixed to the inner wall of the housing 100, facilitating installation and disassembly. Furthermore, fixing the rocker bridge 320 to the inner wall of the housing 100 via a threaded connection ensures good stability of the rocker bridge 320 during operation, avoiding the risk of failure due to loosening.
[0049] like Figures 1 to 3As shown, in some embodiments, the rocker bridge 320 includes a mounting portion 322, an abutment portion 323, a conductive portion 324, and a torsion spring 325. The mounting portion 322 is threadedly connected to the mounting post 140. The abutment portion 323 is located at one end of the mounting portion 322 near the valve switch 310. The conductive portion 324 is located at one end of the mounting portion 322 near the connecting terminal 210. The torsion spring 325 is located inside the mounting portion 322, with one end of the torsion spring 325 contacting the surface of the abutment portion 323. A conductive sheet 321 is located on the conductive portion 324. Thus, under the action of the valve switch 310, the rocker bridge 320 can make the conductive sheet 321 connect and disconnect from the connecting terminal 210, thereby controlling the on / off state of the circuit.
[0050] When the valve switch 310 needs to be opened or closed, it pushes the abutment portion 323 of the rocker bridge 320. Since the rocker bridge 320 is threadedly connected to the mounting post 140, the abutment portion 323 rotates around the mounting post 140 after being pushed by the valve switch 310. As the abutment portion 323 rotates, the conductive plate 321 on the conductive part 324 contacts or separates from the connection terminal 210. When the conductive plate 321 contacts the connection terminal 210, the circuit is open; when the conductive plate 321 separates from the connection terminal 210, the circuit is closed.
[0051] The torsion spring 325 is located inside the mounting portion 322, with one end in contact with the surface of the abutment portion 323 and the other end fixed inside the mounting portion 322. The elastic force of the torsion spring 325 enables the abutment portion 323 to undergo elastic deformation under the pushing force of the valve switch 310, thereby achieving reliable contact or separation between the conductive sheet 321 and the connecting terminal 210.
