[0024] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0025] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] Example 1

[0027] like Figures 1-4 As shown, this utility model embodiment provides a dual-battery switching device with a touch switch, including a battery switching assembly 1. The battery switching assembly 1 includes a battery mounting shell 11, a battery compartment 12, a main battery 13, a main control board 14, a battery connector 15, a battery connector spring 16, a battery contact piece 17, a touch switch 18, and a secondary battery 19.

[0028] A battery compartment 12 is provided on the upper surface of the battery mounting housing 11. A main battery 13 is slidably connected to the inner wall of the battery compartment 12. A main control board 14 is fixedly connected to the lower surface of the battery mounting housing 11. A battery connector 15 is provided on one side of the upper surface of the main control board 14. A plurality of battery connector springs 16 are provided on the upper surface of the battery connector 15. A plurality of battery contact pieces 17 are provided on the lower surface of the main battery 13 near the battery connector 15. The battery contact pieces 17 are in elastic contact with the battery connector springs 16. A touch switch 18 is provided on the upper surface of the main control board 14 near the front of the battery connector 15. The top of the touch switch 18 abuts against one side of the lower surface of the main battery 13. The touch switch 18 is used to send a power supply switching signal to the main control board 14. A secondary battery 19 is provided inside the battery mounting housing 11. The secondary battery 19 is electrically connected to the main control board 14.

[0029] Among them, the battery compartment 12 is a cavity structure with an opening on one side, through which the main battery 13 is inserted or pulled out in the horizontal direction.

[0030] The power supply switching logic between the main battery 13 and the auxiliary battery 19 is as follows:

[0031] When the main battery 13 is pulled out, the touch switch 18 is triggered before the main battery 13 is completely disconnected from the battery connection spring 16. The main control board 14 controls the auxiliary battery 19 to start power supply. The power supply is disconnected after the main battery 13 is completely pulled out. When the main battery 13 is inserted, the battery contact piece 17 of the main battery 13 first contacts the battery connection spring 16. At this time, the main battery 13 and the auxiliary battery 19 are powered at the same time. The touch switch 18 is triggered after the main battery 13 is fully inserted. The main control board 14 controls the auxiliary battery 19 to disconnect power supply.

[0032] In one embodiment, specifically: a charging module 20 is provided in the middle of the upper surface of the main control board 14, the input end of the charging module 20 is electrically connected to the battery connecting spring 16, and the output end of the charging module 20 is electrically connected to the auxiliary battery 19.

[0033] Specifically, when the electronic device is powered on and the main battery 13 is in place, the charging module 20 automatically starts, obtains power from the main battery 13 through the battery connection spring 16 and battery contact piece 17, and charges the auxiliary battery 19 after passing through the internal step-down and constant current constant voltage circuit. During the charging process, the main control board 14 monitors the voltage of the auxiliary battery 19 in real time, and cuts off the charging circuit through the charging module 20 after it is fully charged. The input end of the charging module 20 is electrically connected to the battery connection spring 16, and the output end is soldered to the positive and negative terminals of the auxiliary battery 19 through wires to form an independent charging channel, which does not affect the normal power supply of the electronic device by the main battery 13.

[0034] In one embodiment, specifically: elastic connecting pieces 21 are symmetrically arranged on the inner rear wall and inner front wall of the battery compartment 12. Limiting sliders 22 are fixedly connected to the bottom of the adjacent side of the two elastic connecting pieces 21. Limiting grooves 23 are formed on the front and rear surfaces of the main battery 13. The outer side wall of the limiting slider 22 is slidably connected to the inner side wall of the limiting groove 23. The main battery 13 is limited by sliding along the limiting slider 22 through the limiting groove 23 on the main battery 13, thereby constraining the insertion and removal path of the main battery 13 and ensuring that the electrical connection components (battery contact piece 17 and battery connecting spring piece 16) are accurately aligned.

[0035] In one embodiment, specifically: a limiting groove 24 is provided in the middle of the side of the two limiting sliders 22 that are close to each other, and a limiting block 25 is provided on the side of the inner wall of the two limiting grooves 23 that are close to each other, and the outer wall of the limiting block 25 is attached to the inner wall of the limiting groove 24.

[0036] Specifically, when the main battery 13 is inserted into the battery compartment 12, the limiting groove 24 of the limiting slider 22 and the limiting block 25 of the limiting slide groove 23 are aligned along the insertion and removal path. As the main battery 13 is fully inserted, the elastic force of the elastic connecting piece 21 pushes the limiting slider 22 to move towards the main battery 13, so that the outer wall of the limiting block 25 is fully embedded in the inner wall of the limiting groove 24, forming a mechanical locking structure, thereby preventing the main battery 13 from sliding out of the battery compartment 12. When the main battery 13 is pulled out, an external force greater than the elastic force of the elastic connecting piece 21 needs to be applied to make the limiting block 25 disengage from the limiting groove 24, and the limiting slider 22 moves backward synchronously with the elastic connecting piece 21 to release the locking state.

[0037] In one embodiment, specifically: a positioning block 26 is provided on the lower part of the inner side wall of the battery compartment 12 near the battery connector 15, and a positioning groove 27 is provided on the side of the main battery 13 near the positioning block 26. The outer side wall of the positioning block 26 is slidably connected to the inner side wall of the positioning groove 27. The main battery 13 slides along the positioning block 26 through the positioning groove 27, thereby increasing the stability of the main battery 13 installation.

[0038] In one embodiment, specifically: a first limiting slot 28 is provided on the positioning block 26 near the main battery 13, and a first limiting plug 29 is fixedly connected to the inner side wall of the positioning groove 27 away from the positioning block 26. The outer side wall of the first limiting plug 29 is slidably connected to the inner side wall of the first limiting slot 28. By inserting the first limiting plug 29 on the main battery 13 into the first limiting slot 28, the main battery 13 is limited, preventing the main battery 13 from being misaligned due to external force shaking, and at the same time, preventing the main battery 13 from being accidentally triggered by external force shaking, causing the battery contact piece 17 and the battery connecting spring piece 16 to be misaligned.

[0039] In one embodiment, specifically: a second limiting slot 30 is provided on the upper part of the inner side wall of the battery compartment 12 near the battery connector 15, and a second limiting plug 31 is fixedly connected to the rear part of the main battery 13 near the positioning block 26. The outer side wall of the second limiting plug 31 is slidably connected to the inner side wall of the second limiting slot 30. By inserting the second limiting plug 31 on the main battery 13 into the second limiting slot 30, the position of the main battery 13 after installation is further limited, preventing the battery contact piece 17 from being misaligned with the battery connecting spring piece 16 due to external force shaking of the main battery 13. At the same time, it prevents the touch switch 18 from being accidentally triggered due to external force shaking of the main battery 13.

[0040] In one embodiment, specifically: a bottom shell 32 is fixedly connected to the outer side of the lower surface of the battery mounting shell 11. The bottom shell 32 facilitates the protection of internal electronic components, thereby increasing the stability of equipment operation.

[0041] When this utility model is in operation: in the initial state (without main battery 13), the auxiliary battery 19 independently supplies power to the device through the main control board 14, the touch switch 18 is not triggered, the elastic connecting piece 21 in the battery compartment 12 naturally extends, and the limiting slider 22 separates from the limiting structure of the main battery 13.

[0042] During the insertion of the main battery 13, the user pushes the main battery 13 horizontally into the battery compartment 12 from one side opening. The limiting slide grooves 23 at the front and rear of the main battery 13 slide synchronously along the limiting slider 22 at the bottom of the elastic connecting piece 21, constraining the insertion and removal path and ensuring that the battery contact piece 17 and the battery connecting spring piece 16 gradually align and contact. At this time, the main battery 13 and the auxiliary battery 19 are connected in parallel to provide power. When the main battery 13 is fully inserted, the limiting block 25 is embedded in the limiting groove 24, the first limiting insert 29 is inserted into the first limiting slot 28, and the second limiting insert 31 slides into the second limiting slot 30, forming a triple mechanical lock to prevent the main battery 13 from shaking. At the same time, the trigger boss at the bottom of the main battery 13 presses down the touch switch 18. After receiving the signal, the main control board 14 cuts off the power supply to the auxiliary battery 19 and switches to independent power supply to the main battery 13.

[0043] When the main battery 13 is removed for replacement, the user applies force to overcome the elastic force of the elastic connecting piece 21, causing the main battery 13 to move horizontally. This triggers the boss to disengage from the touch switch 18, and the main control board 14 activates the auxiliary battery 19 to supply power in advance. As the main battery 13 continues to be removed, the battery contact piece 17 and the battery connecting spring piece 16 gradually separate until they are completely separated. At this time, the auxiliary battery 19 has a stable power supply to prevent the device from losing power. During the removal process, the limit structure unlocks in sequence, the elastic connecting piece 21 resets, and it waits for the new battery to be inserted.

[0044] In the charging scenario, when the device is powered on and the main battery 13 is in place, the charging module 20 automatically starts, draws power from the main battery 13 through the battery connection spring 16, and charges the auxiliary battery 19 after step-down and constant current and constant voltage processing; the main control board 14 monitors the voltage of the auxiliary battery 19 in real time, and automatically cuts off the charging circuit after it is fully charged. The whole process does not affect the normal power supply of the main battery 13 to the device.

[0045] Example 2

[0046] like Figure 5 As shown, the dual-battery switching device with a tactile switch provided in this embodiment of the present invention can also achieve free switching between dual batteries by triggering the pin switch 41 through the device battery cover 40.

[0047] Specifically, the device battery cover 40 is a detachable cover that is connected to the battery mounting shell 11 by a buckle and a cover lock, and covers the outside of the main battery 13.

[0048] The pin switch 41 is located inside the battery compartment 12, and its top extends to the corresponding position inside the battery cover 40 of the device, forming a mechanical linkage structure.

[0049] It shares basic components such as the main battery 13, the secondary battery 19, and the main control board 14 with Embodiment 1.

[0050] The power supply switching logic for the device's battery cover 40 to trigger the pin switch 41 to achieve free switching between the two batteries is as follows:

[0051] With the main battery 13 and the auxiliary battery 19 coexisting (battery cover 40 closed):

[0052] The main battery 13 provides priority power supply, and the pin switch 41 is triggered by the pressure of the device battery cover 40, thus disconnecting the power supply circuit of the auxiliary battery 19.

[0053] When the device battery cover 40 is open:

[0054] When the device battery cover 40 is opened, the top of the ejector switch 41 is disengaged from the inside of the device battery cover 40, the state of the ejector switch 41 changes, the main control board 14 activates the auxiliary battery 19 to supply power, and when the main battery 13 has not been removed, the main battery 13 and the auxiliary battery 19 are briefly connected in parallel to supply power.

[0055] After the main battery 13 is completely removed, the main battery 13 is disconnected from the power supply, and the auxiliary battery 19 is powered independently.

[0056] Device battery cover 40 closed scenario (main battery 13 inserted when only auxiliary battery 19 is powered):

[0057] Main battery 13 is inserted into the battery compartment → contact piece 17 contacts spring piece 16 → main battery 13 and auxiliary battery 19 are powered at the same time (the device battery cover 40 is not closed and the pin switch 41 is not triggered).

[0058] When the device battery cover 40 is closed, the pin switch 41 is triggered by pressure, the main control board 14 cuts off the power supply to the auxiliary battery 19, and the main battery 13 is powered independently.

[0059] In summary, this utility model provides a dual-battery switching device with a tactile switch, which includes two triggering schemes: the tactile switch is linked to the insertion or removal of the main battery or the battery cover triggers the pin switch to achieve seamless switching between the main and auxiliary batteries: the auxiliary battery is powered in advance when the main battery is removed / the cover is opened, and the main battery is powered first when the main battery is inserted / closed; at the same time, it supports the main battery to charge the auxiliary battery, which is suitable for electronic devices that require continuous power supply and convenient battery swapping, such as walkie-talkies, industrial terminals, etc.

[0060] Furthermore, the two triggering methods (tactile switch / pin switch) provided in Embodiments 1 and 2 of this utility model can be used independently or in combination to form a redundant design and improve system reliability. For example, the tactile switch can be used as the main trigger, and the pin switch as the backup trigger; the pin switch can be used in mechanical cover devices, and the tactile switch can be used in drawer-type battery compartments without covers.

[0061] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
