The first through hole 1142 of the frame 114 is used to install the button assembly 13, and the first through hole 1142 is inclinedly set at one end of the frame 114. The button assembly 13 is inclinedly installed in the first through hole 1142. Since the first circuit board 14 is located below the first light-emitting component 12 and the button assembly 13, and the button assembly 13 is in contact with the button 141, during installation, it is only necessary to snap the first circuit board 14 into the inner wall of the frame 114, so that the button assembly 13 can be in contact with the button 141 of the first circuit board 14. There is no need to make too many limiting structures on the first circuit board 14. The inclined button assembly 13 is not only convenient for users to press with their fingers, but also simplifies the assembly process, making it more convenient to assemble the flashlight.

[0034] Please refer to Figure 6 and Figure 7 , Figure 6 This is a perspective view of the frame of the flashlight according to this utility model. Figure 7This is a perspective view of the button assembly of the flashlight according to this utility model. The button assembly 13 includes a connecting post 131 and cones 133 and pressure plates 132 located at both ends of the connecting post 131. The cones 133 are attached to the button 141.

The first through hole 1142 includes a first circular hole and a second circular hole. The first circular hole is close to the outer side of the frame 114, and the diameter of the first circular hole is larger than the diameter of the second circular hole. The diameter of a circular hole is greater than or equal to the diameter of the pressure plate 132, which facilitates the user's pressing. The connecting post 131 is used to extend the length between the pressure plate 132 and the cone 133, so that the cone 133 can extend into the cavity 1141 and fit against the button 141. At the same time, the diameter of the pressure plate 132 is greater than the diameter of the first circular hole to prevent the pressure plate 132 from entering the second circular hole when pressed. The first circular hole is also used to limit the spacing of the pressure plate 132 when pressed, so as to prevent the pressure plate 132 from damaging the button 141 when pressed.

[0035] The button assembly 13 also includes a reset spring 134 and a limiting post 136. The reset spring 134 is sleeved on the connecting post 131 and located inside the first circular hole.

The end of the limit post 136 is located in the second through hole 1143, and the other end of the limit post 136 is engaged in the first annular groove. The reset spring 134 is used to reset the pressure plate 132. After the pressure plate 132 is pressed down, it is easy for the pressure plate 132 to return to the initial position so that it can be pressed again. The limit post 136 is used to further limit the button assembly 13, further increasing the stability of the button assembly 13's reset. At the same time, one end of the limit post 136 is connected in the second through hole 1143 and is limited by the first side plate 115, thereby preventing the limit post 136 from separating from the frame 114.

[0036] A sealing ring 135 is also provided on the connecting post 131, and a second annular groove is also provided on the connecting post 131. The sealing ring 135 is located in the second annular groove. When the sealing ring 135 is installed in the first through hole 1142, the sealing ring 135 fits against the inner wall of the second circular hole. The second annular groove is used to install the sealing ring 135 and prevent the sealing ring 135 from separating from the connecting post 131 when the connecting post 131 moves. The sealing ring 135 is used for waterproofing and to prevent water droplets from entering the frame 114 from the position of the first through hole 1142 and causing damage to the first circuit board 14.

[0037] The inner wall of the frame 114 near the first side plate 115 is provided with symmetrical snap-fit ​​grooves 1144, which are close to one end of the button assembly 13. The first circuit board 14 near the first side plate 115 is provided with symmetrical first lugs, which are located in the snap-fit ​​grooves 1144. The snap-fit ​​grooves 1144 are used to install second lugs. After the first lugs of the first circuit board 14 are installed in the snap-fit ​​grooves 1144, they are limited by the first side plate 115, so that the first circuit board 14 is stably connected to the frame 114, preventing the first circuit board 14 from separating from the frame 114. At the same time, it also makes it easy for the button assembly 13 to stably press the button 141 on the first circuit board 14.

[0038] A fixing block 111 is also provided at one end of the frame 114 near the button assembly 13 and the first light-emitting assembly 12. The fixing block 111 is provided with an inclined surface 112 and a through groove 113. The inclined surface 112 is located at one end of the fixing block 111, and the first through hole 1142 is located inside the inclined surface 112. The first light-emitting assembly 12 is located at the other end of the fixing block 111, and the through groove 113 is located between the light-emitting assembly and the button assembly 13. The through groove 113 extends along the thickness direction of the frame 114. The fixing block 111 is used to increase the rigidity of the frame 114. The first through hole 1142 is opened on the fixing block 111 to prevent the side wall of the first through hole 1142 from breaking, so that the button assembly 13 can be stably installed in the first through hole 1142. The through groove 113 is used to reduce the weight of the frame 114. At the same time, it is also convenient to tie the lanyard to the fixing block 111 to prevent the flashlight from being lost.

[0039] The frame 114 is also provided with a second light-emitting component and a second side plate 116. The light source of the second light-emitting component is close to the side of the second side plate 116. The first side plate 115 and the second side plate 116 are respectively located on both sides of the frame 114. The second light-emitting component is used to make the side of the frame 114 emit light, increasing the light-emitting surface of the flashlight and thus increasing the versatility of the flashlight. At the same time, the second side plate 116 is used to enclose the second light-emitting component inside the frame 114 to prevent foreign objects from entering the frame 114.

[0040] The second light-emitting component includes a second circuit board 15 and multiple rows of LED beads evenly arranged on the second circuit board 15; symmetrical second lugs are also provided at both ends of the other side of the first circuit board 14. A clearance groove is provided at the position opposite to the second lugs on the second circuit board 15. The second lugs are installed in the clearance groove. The second circuit board 15 is used to install LED beads, and the clearance groove is used to install the second lugs, so that the second lugs can extend into the clearance groove. On the one hand, the second lugs of the first circuit board 14 are used to limit the second circuit board 15 and prevent the second circuit board 15 from shaking in the frame 114. On the other hand, the second circuit board 15 is also used to limit the first circuit board 14. When the button assembly 13 presses the button 141, it prevents the position of the button assembly 13 from shifting, so that the button assembly 13 can stably press the button 141.

[0041] In this embodiment, a storage battery 16 is also provided below the first circuit board 14. The storage battery 16 is used to provide power to the flashlight, making it convenient for users to carry when going out.

[0042] A limiting frame 1145 for limiting the second circuit board 15 is provided on the inner wall of the frame 114 near the second side plate 116. The edge of the second circuit board 15 is attached to the limiting frame 1145. The limiting frame 1145 is used to attach to the edge of the circuit board and to limit the second circuit board 15 to prevent the second circuit board 15 from shaking or moving inside the frame 114.

[0043] The second side panel 116 is made of a light-transmitting material. The light-transmitting material of the second side panel 116 facilitates the emission of light energy from the second circuit board 15 onto the object. The light-transmitting material can be glass, acrylic sheet, etc.

[0044] Working principle: When installing the flashlight, firstly, install the first light-emitting component 12 on the frame 114. Insert one end of the cone 133 of the connecting post 131 into the first through hole 1142. Due to the action of the return spring 134 and the pressure plate 132, the return spring 134 limits the pressure plate 132 within the first circular hole. Then, insert the limiting post 136 into the second through hole 1143, so that one end of the limiting post 136 passes through the second through hole 1143 and is located within the first annular groove. Since the button assembly 13 is installed at an angle within the mounting frame, when the limiting post... Position 136 is located within the first annular groove. The limiting post 136 effectively prevents the button assembly 13 from separating from the frame 114. Simultaneously, it further stabilizes the button assembly 13 upon reset. Furthermore, the second protrusion of the first circuit board 14 extends into the clearance groove of the second circuit board 15, causing one side of the first circuit board 14 to engage with the second circuit board 15. The assembled first circuit board 14 and second circuit board 15 are then inserted into the frame 114, ensuring the edge of the second circuit board 15 fits against the limiting frame 1145. Simultaneously, the first circuit... The first protrusion of plate 14 engages with the slot 1144, and the storage battery 16 is installed inside the frame. Finally, the first side plate 115 and the second side plate 116 are respectively installed on both sides of the frame 114. The second side plate 116 is located on the side closer to the second circuit board 15. When the button assembly 13 is pressed, it is used to squeeze the pressure plate 132. The pressure plate 132 squeezes the return spring 134, causing the return spring 134 to deform. At the same time, the cone 133 squeezes the button 141 to control the first light-emitting component 12 and the second light-emitting component 141. When the pressure plate 132 is released, the reset spring 134 restores its deformation and presses the pressure plate 132 in the opposite direction to reset the pressure plate 132. Due to the action of the limiting post 136, when the limiting post 136 is in contact with the cone 133, the limiting post 136 prevents the pressure plate 132 from continuing to move, so that the button assembly 13 is stably connected in the frame 114. The above structure is simple, and the frame 114 does not need to limit or position the first circuit board 14. This not only saves the internal space of the flashlight, but also makes assembly more convenient.

[0045] The flashlight of this preferred embodiment passes.

[0046] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
