[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solution: a switch trigger mechanism, comprising a housing, an energy pack with a switch inside the housing, and a bottom cover that closes with the housing, wherein a trigger assembly is provided on the bottom cover; wherein, when the bottom cover is closed with the housing, the trigger assembly is configured to trigger the switch of the energy pack.

[0007] Preferably, the trigger component includes:

[0008] a trigger button, the trigger button being arranged on the bottom cover;

[0009] A fixing assembly, wherein the trigger button is fixed on the bottom cover via the fixing assembly.

[0010] Preferably, the trigger button is provided with two opposite ends, one end of the trigger button is provided with a first positioning hole, and the other end is provided with a positioning groove, and the fixing assembly includes:

[0011] a second positioning hole, the second positioning hole being formed on the bottom cover and adapted to fit the first positioning hole;

[0012] A positioning post is provided on the bottom cover and is matched with the positioning groove.

[0013] Preferably, the trigger button is made of flexible material.

[0014] Preferably, the bottom cover is provided with a positioning protrusion, and the trigger button is provided with a corresponding recessed portion.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The energy pack's automatic power-on function is achieved through the coordination of a push button and an energy pack contact. When the bottom cover is closed, the push button triggers the energy pack contact, automatically activating the energy pack's power supply. When the bottom cover is opened, the push button no longer contacts the energy pack contact, and the energy pack automatically stops supplying power. This design eliminates the need for additional power-on steps, simplifies the operation process, ensures effective triggering of the energy pack, and improves ease of use and reliability.

[0026] Example

[0027] See also Figure 1-4 As shown, the present invention provides a technical solution for a switch trigger mechanism: a switch trigger mechanism, comprising a housing 1, an energy pack 2 with a switch in the housing 1, and a bottom cover 3 that cooperates with the housing 1 to close, and a trigger assembly 4 is provided on the bottom cover 3; wherein, when the bottom cover 3 is closed with the housing 1, the trigger assembly 4 is configured to trigger the switch of the energy pack 2.

[0028] In this embodiment, the bottom opening of the housing 1 is rotatably connected to the bottom cover 3. The energy pack trigger 201 is designed to energize when activated and de-energize when not activated. This structure is commonly found in devices such as mice and keyboards and is state-of-the-art, so its specific implementation details will not be elaborated on.

[0029] The trigger assembly 4 includes a trigger button 401 and a fixing assembly 402 . The trigger button 401 is disposed on the bottom cover 3 and is fixed to the bottom cover 3 via the fixing assembly 402 .

[0030] like Figure 3 As shown, the trigger button 401 is provided with two opposite ends, one end of the trigger button 401 is provided with a first positioning hole 4011, and the other end is provided with a positioning groove 4012; Figure 4As shown, the fixing assembly 402 includes: a second positioning hole 4021 and a positioning column 4022 . The second positioning hole 4021 is opened on the bottom cover 3 and matches the first positioning hole 4011 . The positioning column 4022 is provided on the bottom cover 3 and matches the positioning groove 4012 .

[0031] In this embodiment, after the trigger button 401 is installed, the first positioning hole 4011 and the second positioning hole 4021 can be fixed by bolts, and the other end can be positioned by the positioning groove 4012 and the positioning column 4022 so that its position does not change after installation.

[0032] The trigger button 401 is made of a flexible material, such as silicone and rubber. These materials have good elasticity and durability, can adapt to changes in external forces during use, and effectively avoid pressure damage to the energy pack trigger button 201, thereby ensuring the stability and reliability of the triggering process.

[0033] The bottom cover 3 is provided with a positioning protrusion 5, and the trigger button 401 is provided with a matching recessed portion 6. This design can effectively limit the position of the trigger button 401, prevent the contact portion of the trigger button 401 from shifting during use, and improve the accuracy of the pressed contact position.

[0034] The working principle of the present invention is as follows:

[0035] During use, the operator closes the bottom cover 3. When the bottom cover 3 and the outer shell 1 are closed, the trigger button 401 contacts the energy pack contact button 201. As the operator continues to apply pressure, the bottom cover 3 and the outer shell 1 are completely closed, and the trigger button 401 applies pressure to the energy pack contact button 201, ensuring that the energy pack is properly powered and maintains its power supply. This design eliminates the need for the operator to perform additional power-up operations on the energy pack; it can be used directly after installation, simplifying the operation process and improving ease of use.

[0036] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
