[0042] With reference to Figure 1 and Figure 3 , the housing 100 is used to accommodate components such as the bracket 200, the circuit assembly 400, and the power supply assembly 300. The specific structure of the housing 100 can be determined according to the actual situation. In some embodiments of the present application, the housing 100 is taken as an example of being "runway-shaped" for description.

[0043] With reference toFigure 2 and Figure 3 , the bracket 200 is disposed through the housing 100. In some embodiments, the bracket 200 may be completely disposed through the interior of the housing 100. In other embodiments, the bracket 200 may also be partially disposed through the housing 100. Some embodiments of the present application will be described by taking the bracket 200 being completely disposed through the housing 100 as an example. Referring to Figure 4 , the bracket 200 may define a receiving cavity 210, and the receiving cavity 210 may accommodate a power supply assembly 300 and the like. The power supply assembly 300 is used to supply power to the flash 10. It can be understood that the power supply assembly 300 may be disposed in the receiving cavity 210.

Specifically, the circuit assembly 400 includes a first circuit board 410 and a second circuit board 420. In some embodiments, the first circuit board 410 may be the main board, and the second circuit board 420 may be the lamp board. In other embodiments, the first circuit board 410 may also be the lamp board, and the second circuit board 420 may also be the main board. Some embodiments of the present application will be described by taking the first circuit board 410 as the main board and the second circuit board 420 as the lamp board as an example. It can be understood that the main board is the core component in the flash 10 and can control the entire flash 10 system. The main board can process and output signals, and control the working mode, flash intensity, flash timing, etc. of the flash 10 according to preset parameters. The lamp board can emit flashes and connect to the lamp body.

[0045] The following introduces the specific installation positions of the circuit assembly 400. Both the first circuit board 410 and the second circuit board 420 are connected to the bracket 200. Specifically, the first circuit board 410 may be screwed or snapped to the bracket 200, and the second circuit board 420 may be screwed or snapped to the bracket 200. Moreover, the first circuit board 410 may be disposed in the receiving cavity 210, and the second circuit board 420 may be disposed outside the receiving cavity 210, that is, the installation and disassembly operations of the first circuit board 410 are independent of those of the second circuit board 420.

[0046] In the technical solution of the present utility model, the flash 10 includes a housing 100, a bracket 200, a power supply assembly 300, and a circuit assembly 400. The bracket 200 is inserted into the housing 100 and defines a receiving cavity 210. The power supply assembly 300 is disposed in the receiving cavity 210. The circuit assembly 400 is electrically connected to the power supply assembly 300. In the prior art, the main board and the control board of the flash are stacked inside the bracket, resulting in inconvenient disassembly of a single board. In this solution, both the first circuit board 410 and the second circuit board 420 of the circuit assembly 400 are connected to the bracket 200. The first circuit board 410 is disposed in the receiving cavity 210 of the bracket 200, and the second circuit board 420 is disposed outside the receiving cavity 210 of the bracket 200. Therefore, when relevant maintenance operations need to be performed, in this solution, the first circuit board 410 can be directly separated from the bracket 200 or the second circuit board 420 can be separated from the bracket 200. The overall operation is convenient and fast, and the maintenance efficiency can be effectively improved. Moreover, in this solution, the circuit assembly 400 and the power supply assembly 300 can be first connected to the bracket 200, and then the bracket 200 is inserted through the housing 100 to achieve the overall assembly connection. Compared with the solution in which the circuit assembly and the power supply are assembled and connected inside the housing, this solution can avoid the interference of the housing 100 and effectively improve the convenience of overall disassembly and assembly of the flash 10.

In some embodiments, the bracket 200 includes a first opening 220, and the first opening 220 can communicate with the receiving cavity 210. The power supply assembly 300 can enter the receiving cavity 210 through the first opening 220. The bracket 200 includes a back plate 230 disposed opposite to the first opening 220. Taking the orientation in Figure 4 as a reference, the first opening 220 can be an opening on the front side of the bracket 200, and the back plate 230 can be a plate body on the rear side of the bracket 200 opposite to the first opening 220. The first circuit board 410 is disposed between the back plate 230 and the power supply assembly 300. Specifically, the first circuit board 410 can be laid on the side of the back plate 230 facing the first opening 220. The power supply assembly 300 of this solution can limit the first circuit board 410, effectively improving the stability of the assembly connection of the first circuit board 410, and can make full use of the internal space of the bracket 200 to optimize its spatial layout.

[0048] Referring to Figure 2 and Figure 3, the specific connection settings between the first circuit board 410 and the backplane 230 are introduced below. In some embodiments, the backplane 230 has a second opening 231, and the second opening 231 can communicate with the accommodation cavity 210, that is, the second opening 231 can be arranged opposite to the first opening 220. Among them, along the axis direction parallel to the first opening 220, the first circuit board 410 at least partially covers the second opening 231. It should be noted that the first circuit board 410 can partially cover the second opening 231 or completely cover the second opening 231, and the specific setting of the first circuit board 410 can be determined according to the actual situation. For the convenience of description and understanding, it is defined that the plane of the backplane 230 facing the first opening 220 is the projection plane. Along the axis direction parallel to the first opening 220, the first circuit board 410 forms a first orthographic projection on the projection plane, and the backplane 230 forms a second orthographic projection on the projection plane, that is, the first orthographic projection can be arranged at least partially coincident with the second orthographic projection.

[0049] The backplane 230 of this solution is provided with a second opening 231, that is, when the backplane 230 and the first circuit board 410 are assembled and connected by screws from the side of the backplane 230 facing away from the first opening 220, the arrangement position of the first circuit board 410 can be observed and adjusted through the second opening 231, ensuring the assembly connection accuracy and assembly stability of the first circuit board 410, and also reducing the processing materials of the bracket 200 and lowering the production cost.

[0050] Refer to Figure 2 and Figure 3 , the specific setting of the third circuit board 430 is introduced below. In some embodiments, the circuit assembly 400 includes a third circuit board 430.

The user can adjust the parameters of the flash lamp 10 through the control board, such as adjusting the flash intensity, changing the flash mode, etc. The control board and the main board are signal-connected, that is, the interaction between the user operation and the main board control can be realized. It can be understood that the third circuit board 430 can be electrically connected to the power supply assembly 300, and the third circuit board 430 can be arranged outside the accommodation cavity 210 and connected to the bracket 200.

[0051] It should be noted that in some embodiments, the third circuit board 430 can be arranged adjacent to the second circuit board 420. In other embodiments, the third circuit board 430 can also be arranged opposite to the second circuit board 420. Some embodiments of the present application are described by taking the third circuit board 430 and the second circuit board 420 being arranged opposite to each other as an example.

[0052] Refer to Figure 2 and Figure 3, the following introduces the specific installation positions of the second circuit board 420 and the third circuit board 430 on the bracket 200. In some embodiments, the bracket 200 includes a first baffle 240 and a second baffle 250 arranged opposite to each other, so as to Figure 3 Taking the orientation in

[0053] as a reference, the baffle on the upper side of the bracket 200 can be the first baffle 240, and the baffle on the lower side of the bracket 200 can be the second baffle 250. The structure of the first baffle 240 can be the same as or different from that of the second baffle 250. In some embodiments of the present application, the case where the structures of the first baffle 240 and the second baffle 250 are different is taken as an example for illustration. It can be understood that both the first baffle 240 and the second baffle 250 are used to define the accommodation cavity 210.

In some other embodiments, the baffle on the right side of the bracket 200 can be the third baffle 260. In some embodiments of the present application, the case where the baffle on the right side of the bracket 200 is the third baffle 260 is taken as an example for illustration.

[0055] In some embodiments, the third baffle 260 has a first side wall 261 facing away from the back plate 230, and the first baffle 240 includes a second side wall 241 facing away from the back plate 230. The second side wall 241 is located on the side of the first side wall 261 facing away from the back plate 230, that is, the distance from the second side wall 241 to the back plate 230 is greater than the distance from the first side wall 261 to the back plate 230. In other words, the extension height of the first baffle 240 relative to the back plate 230 is greater than the extension height of the third baffle 260 relative to the back plate 230. This solution can form a notch on one side of the third baffle 260 of the bracket 200, facilitating the installation and removal of the power supply assembly 300 and effectively reducing the situation of the power supply assembly 300 being knocked or bumped.

In other words, the arrangement height of the second baffle 250 relative to the back plate 230 is greater than the arrangement height of the third baffle 260 relative to the back plate 230. This solution can form a notch on one side of the third baffle 260 of the bracket 200, facilitating the installation and removal of the power supply assembly 300 and effectively reducing the situation of the power supply assembly 300 being knocked or bumped.

Compared with the solution of connecting the first circuit board and the second circuit board with wires, this solution can omit the arrangement of wires and improve the stability of the electrical connection between the first circuit board 410 and the second circuit board 420. It can be understood that multiple first electrical connectors 500 can be provided to connect the first circuit board 410 and the second circuit board 420. Similarly, a second electrical connector can also be added to connect the first circuit board 410 and the third circuit board 430, and its specific setting will not be elaborated here.

Specifically, the battery cell can supply power to the circuit system of the flash 10 to drive the charging part and the bulb of the flash 10 to emit light. The battery cell can provide a continuous and stable power supply according to its capacity, voltage and other parameters to support the normal operation of the flash 10. The capacitor can store electric charges and can release a large amount of electrical energy in a short time to supply a strong current for the bulb to generate a strong flash when shooting.

In other embodiments, the bracket 200 may be provided with a square hole 290, that is, it can avoid the welding wire of the battery cell and optimize the structural layout of each component inside the bracket 200.
