Technical Field

[0001] This utility model relates to the field of electronic product disassembly and assembly technology, and in particular to an automatic power-off structure and electronic product. Background Technology

[0002] When disassembling electronic products, in order to prevent metal parts (such as screws) from falling into the motherboard and causing a short circuit and damaging the device, it is required that the battery be removed first during disassembly. That is, the battery should be removed before performing other operations, and the operation should be carried out when there is no power.

[0003] Currently, the only requirement in the operating procedure is that operators must remove the battery after disassembling the product casing before proceeding with other steps. This method is not foolproof and relies entirely on whether the operator strictly follows the operating procedure. There is still a risk that metal parts may fall onto the motherboard, causing a short circuit and damaging the device. Utility Model Content

[0030] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] This utility model provides an automatic power-off structure, including a connector assembly, a trigger assembly, and a reset assembly. The connector assembly can realize on / off switching, controlling the connection or disconnection of the battery. The trigger assembly is used to connect the connector assembly with the cooperation of the electronic product housing. The reset assembly drives the trigger assembly to automatically reset after the force of the trigger assembly disappears, causing the connector assembly to disconnect.

[0032] The following description, in conjunction with the accompanying drawings, details the components, their positional relationships, and their connections in the automatic power-off structure provided by this utility model embodiment.

[0033] like Figure 1 and Figure 2 As shown in this embodiment of the present invention, the connector assembly 10 includes a board-end connector 11 and a battery connector 12. The board-end connector 11 is used to connect to the motherboard of the electronic product, and the battery connector 12 is connected to the battery that powers the motherboard. When the board-end connector 11 and the battery connector 12 are connected, the battery can power the motherboard normally. When the board-end connector 11 and the battery connector 12 are disconnected, the battery cannot power the motherboard.

[0034] The battery connector 12 includes a movable contact 13, and the board connector 11 includes a fixed contact. When the board connector 11 and the battery connector 12 are in a connected state, the movable contact 13 moves to the position of the fixed contact and abuts to conduct electricity. When the board connector 11 and the battery connector 12 are in a disconnected state, the movable contact 13 moves to separate from the fixed contact.

[0035] like Figure 2 As shown, the board-end connector 11 and the battery connector 12 include multiple sets of pins 14 and slots 15. As shown, the board-end connector 11 and the battery connector 12 have connecting end faces that are in contact with each other. Pins 14 are disposed on the connecting end face of the board-end connector 11, and slots 15 are disposed on the connecting end face of the battery connector 12. When the board-end connector 11 and the battery connector 12 are connected, the pins 14 are inserted into the slots 15.

[0036] Fixed contacts are provided on both sides of the pin 14, and movable contacts 13 are provided in the slot 15. The slot 15 includes a space for the movable contacts 13 to move closer to or separate from the fixed contacts. For example, contacts are provided on both sides of the pin 14 in the slot 15, one of which is a movable contact 13, and the other is fixedly provided on the inner wall of the slot 15. When the pin 14 is inserted into the slot 15, the fixed contact on one side of the pin 14 is connected to the contact on the inner wall of the slot 15, and the fixed contact on the other side of the pin 14 is connected to or disconnected from the movable contact 13.

[0037] Continue to refer to Figure 2 As shown, a limiting structure is also provided between the board connector 11 and the battery connector 12. For example, the limiting structure includes a limiting protrusion 16 and a limiting groove 17. The limiting protrusion 16 and the limiting groove 17 are respectively provided on the connection end faces of the board connector 11 and the battery connector 12. When the board connector 11 and the battery connector 12 are connected, the limiting protrusion 16 is inserted into the limiting groove 17, thereby limiting the relative position of the board connector 11 and the battery connector 12.

[0038] In this embodiment of the application, the trigger component 20 is connected to the movable contact piece 13. The trigger component 20 is used to drive the movable contact piece 13 to move, so that the movable contact piece 13 abuts against the board end connector 11, thereby realizing the connection between the board end connector 11 and the battery connector 12.

[0039] The trigger component 20 is used to drive the movable contact 13 to move. In the electronic product, the trigger component 20 cooperates with the housing of the electronic product. When the housing is installed, the housing presses down on the trigger component 20 to move, so that the trigger component 20 drives the movable contact 13 to move.

[0040] For example, such as Figures 3 to 5 As shown, the trigger assembly 20 includes a driving part 21 and a driven part 22, and a movable contact 13 is connected to the driven part 22. The driving part 21 is used to press and move a set stroke through the electronic product housing. During the movement of the driving part 21, the driven part 22 and the movable contact 13 are driven to move synchronously. When the driving part 21 is in the set position, the movable contact 13 abuts against the board end connector 11.

[0041] For example, the moving direction of the drive unit 21 is perpendicular to the surface direction of the plate end connector 11 and the battery connector 12, and the driven unit 22 is provided on the surface of the battery connector 12 and moves on the surface of the battery connector 12.

[0042] Continue to refer to Figures 3 to 5 As shown, for example, the driving part 21 includes a pressing post 211, the outer wall of which includes a guide surface 212. The driven part 22 includes a main transmission rod 221 and a side transmission rod 222. One end of the side transmission rod 222 is connected to the outer wall of the main transmission rod 221, and the other end is connected to the movable contact piece 13. One end of the main transmission rod 221 is slidably connected to the guide surface 212. For example, the cross-sectional shape of one end of the main transmission rod 221 is arc-shaped, and it slides in cooperation with the guide surface 212.

[0043] During the operation of the trigger component 20, the pressing post 211 moves by pressing through the electronic product housing, and the guide surface 212 drives the main transmission rod 221, the side transmission rod 222 and the movable contact piece 13 to move synchronously. When the pressing post 211 is pressed into place by the housing, the movable contact piece 13 fits with the fixed contact piece, so that the board end connector 11 and the battery connector 12 are connected.

[0044] For example, the pressing post 211 includes a tapered guide surface, and the outer diameter of the tapered guide surface gradually decreases along the pressing direction of the pressing post 211; the pressing direction of the pressing post 211 is perpendicular to the moving direction of the main transmission rod 221, and as the pressing post 211 moves, the tapered guide surface drives the main transmission rod 221 to gradually move away from the pressing post 211.

[0045] like Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, each slot 15 is provided with a movable contact piece 13; the side conduction rod 222 is located outside the slot 15, and the other end of the side conduction rod 222 is connected to the through rod 223, which passes through the side wall of the slot 15 and is connected to the movable contact piece 13.

[0046] The through rod 223 is parallel to the main conduction rod 221, and the side conduction rods 222 are respectively perpendicular to the through rod 223 and the main conduction rod 221. For example, as shown in the figure, two side conduction rods 222 are connected to each main conduction rod 221. Correspondingly, two sets of pins 14 and slots 15 are provided at the corresponding positions of the board end connector 11 and the battery connector 12.

[0047] In this embodiment of the invention, the multiple pins 14 and slots 15 are multiple pins, corresponding to different power supply modules of the motherboard.

[0048] In this embodiment of the present invention, the driven part 22 includes two main transmission rods 221, which are symmetrically arranged with the axis of the pressing column 211 as the center; the pressing column 211 is used to synchronously drive the two main transmission rods 221 to move.

[0049] Two main transmission rods 221 are moved simultaneously by a pressing column 211. Multiple side transmission rods 222 are respectively arranged on the two main transmission rods 221. When the two main transmission rods 221 are driven by the pressing column 211, they move in opposite directions. The corresponding side transmission rods 222, through rods 223 and movable contact pieces 13 connected to through rods 223 move in opposite directions. Therefore, it is necessary to arrange the two sets of side transmission rods 222, through rods 223 and movable contact pieces 13 connected to through rods 223 symmetrically.

[0050] like Figures 5 to 7 As shown in the embodiment of this utility model, the reset component 30 is connected to the trigger component 20. The reset component 30 is used to drive the movable contact 13 to move in the opposite direction, so that the movable contact 13 is released from contact with the board end connector 11, thereby de-energizing the board end connector 11 and the battery connector 12.

[0051] When the trigger component 20 moves, it overcomes the elastic force of the reset component 30, causing the reset component 30 to compress and store energy. When the force applied to the trigger component 20 is released, the reset component 30 resets, the trigger component 20 moves in the opposite direction, and the main transmission rod 221, the side transmission rod 222 and the movable contact piece 13 all move in the opposite direction, thereby separating the movable contact piece 13 from the fixed contact piece, and realizing the power-off of the board end connector 11 and the battery connector 12.

[0052] For example, the reset assembly 30 includes a first elastic reset structure 31, which is connected to the main transmission rod 221. If the first elastic reset structure 31 is a spring, one end of the spring is connected to the end of the main transmission rod 221 away from the pressing post 211, and the other end abuts against the battery connector 12.

[0053] When the pressing column 211 drives the main transmission rod 221 to move, the first elastic reset structure 31 is compressed as the main transmission rod 221 moves. When the force of the pressing column 211 is eliminated, the force on the first elastic reset structure 31 disappears, and the first elastic reset structure 31 resets and drives the main transmission rod 221 to move in the opposite direction.

[0054] For example, the reset assembly 30 includes a second elastic reset structure 32; the second elastic reset structure 32 is connected to the pressing post 211. If the second elastic reset structure 32 is a spring, a groove is provided on the battery connector 12, the second elastic reset structure 32 is disposed in the groove, one end of the spring abuts against one end of the pressing post 211, and the other end abuts against the bottom of the groove.

[0055] When the pressing column 211 is pressed and moved, the second elastic reset structure 32 is compressed synchronously. When the force of the pressing column 211 is eliminated, the force on the second elastic reset structure 32 disappears, and the second elastic reset structure 32 resets and drives the pressing column 211 to move in the opposite direction.

[0056] In this embodiment of the utility model, the first elastic reset structure 31 and the second elastic reset structure 32 can be provided simultaneously, or one of them can be selected.

[0057] This utility model embodiment provides an electronic product including the aforementioned automatic power-off structure. The electronic product includes a motherboard, a battery, and a casing, etc. The motherboard is connected to the board-end connector 11, and the battery is connected to the battery connector 12.

[0058] Taking a laptop as an example, when assembling the back cover of the laptop, the trigger component 20 is pressed by the back cover, the reset component 30 is compressed, the movable contact 13 is connected to the fixed contact, and the battery can supply power to the motherboard; when the laptop is disassembled, the back cover of the casing is removed, the force of the trigger component 20 disappears, the reset component 30 drives the trigger component 20 to move in the opposite direction, so that the movable contact 13 is separated from the fixed contact, and the battery cannot supply power to the motherboard.

[0059] This utility model provides an automatic power-off structure and electronic product. During installation of the electronic product's casing, the casing presses against a trigger component 20, which drives a movable contact piece 13. Once the casing is in place, the movable contact piece 13 abuts against the board-end connector 11, establishing electrical connection and allowing the battery to supply power. When the casing is removed, the casing no longer applies pressure to the trigger component. Under the action of a reset component 30, the movable contact piece 13 moves in the opposite direction, releasing its contact with the board-end connector 11, thus de-energizing both the board-end connector 11 and the battery connector 12. This utility model's technical solution, with its automatic power-off structure working in conjunction with the electronic product casing, automatically de-energizes the battery after casing removal, providing a foolproof protection effect. Furthermore, it eliminates the need to disassemble the battery during non-battery-related operations, improving operational safety and convenience.
