[0028] Please refer to Figures 1 to 5 , the present utility model provides a housing structure 100, which is applied to a light therapy instrument (not shown in the figure), and includes: a first housing 10, the first housing 10 includes a first mounting portion 11; a second housing 20, the second housing 20 includes a second mounting portion 21, and the first mounting portion 11 is detachably connected to the second mounting portion 21; and a housing assembly 30, the second housing 20 is detachably mounted in the housing assembly 30.

[0029] Specifically, the light therapy instrument includes a first housing 10, a second housing 20, and a housing assembly 30. The first housing 10 is connected to the second housing 20, and the second housing 20 is integrally installed inside the housing assembly 30. The housing assembly 30 covers the outside of the second housing 20 to provide protection and support.

[0030] A first mounting portion 11 is provided on the first housing 10, and a second mounting portion 21 is provided on the second housing 20. The first housing 10 is mounted on the second housing 20 through the detachable connection between the first mounting portion 11 and the second mounting portion 21. The specific structures of the first mounting portion 11 and the second mounting portion 21 can be selected according to actual needs, and can be set as structures such as screws, or can also be set as mating structures such as buckles. The positions of the first mounting portion 11 and the second mounting portion 21 can also be set according to actual needs, and can be set on the end face or on the side wall.

[0031] As Figure 3 , the first housing 10 is connected to one end of the second housing 20, and a first mounting space is formed between the first housing 10 and the second housing 20 for mounting components located at the front end of the light therapy instrument, such as a lens 50 or a decorative ring 60, etc.; a second mounting space is formed inside the second housing 20 for mounting internal components of the light therapy instrument, such as a battery, a lamp board assembly, a heat dissipation assembly, etc.; a third mounting space is formed between the second housing 20 and the housing assembly 30 for mounting components such as a circuit board 40. When electrical components that need to be installed and matched are required, they can be integrally installed in the same mounting space, with simple assembly and convenient installation.

[0032] The first housing 10, the second housing 20, and the housing assembly 30 are assembled with each other to form a stacked structure of the light therapy device. The stacked structure can effectively utilize space, improve space utilization rate, and make the device more compact. Each stacked layer can be regarded as an independent module, which can make it easier to align and fix each component during stacked installation, quickly assemble, reduce assembly time, improve production efficiency, and also facilitate later maintenance or replacement, increasing the flexibility and scalability of the light therapy device. At the same time, in the stacked structure, a heat dissipation channel is reserved, such as Figure 3 , which can effectively dissipate heat, avoid local overheating, and maintain the overall performance of the light therapy device. The light therapy device adopts this housing structure 100, making the overall volume of the light therapy device product small and convenient for carrying and use.

[0033] The technical solution of the present utility model forms a stacked structure of the light therapy device by arranging the first housing 10, the second housing 20 and the housing assembly 30 in cooperation, which can reduce the connection requirements between components, adopt an integrated design, be convenient for assembly when installing the internal structure, simplify the assembly process, facilitate the internal structure components and connections, and make the overall structure more stable. Through stacking, the space utilization is optimized, more functions can be integrated in a limited space, the volume of the light therapy device is miniaturized, and the compactness of the structure of the light therapy device is maintained.

[0034] In an embodiment of the present utility model, a circuit board 40 is installed on the second housing 20; the first mounting portion 11 protrudes from the end face of the first housing 10; the second mounting portion 21 protrudes towards the first mounting portion 11, and at least a part of the first mounting portion 11 overlaps with the second mounting portion 21 and is fixedly connected at the overlapping position.

[0035] Specifically, as Figure 3 , the circuit board 40 is installed on the second housing 20, and the circuit board 40 is located between the second housing 20 and the housing assembly 30 and is adjacent to the first housing 10. At this time, the installation of the first housing 10 and the second housing 20 may interfere with the circuit board 40. For example, if the first housing 10 and the second housing 20 are connected by screws, and the connection direction of the screws is along the plane direction of the circuit board 40, when using tools to tighten the screws, the tools will interfere with the circuit board 40, making it difficult to assemble, and it may hit the circuit board 40, causing damage to the circuit board 40.

[0036] In this embodiment, as Figure 3, the first mounting portion 11 protrudes from the end face of the first housing 10, and the second mounting portion 21 protrudes along the second housing 20 towards the first mounting portion 11. As a result, the first mounting portion 11 and the second mounting portion 21 are overlapped and fixed at the overlapping position. That is, the first mounting portion 11 and the second mounting portion 21 are connected in a direction opposite to each other. At this time, the connection direction at the overlapping position is misaligned with the board surface direction of the circuit board 40. Therefore, when using a tool for installation, the tool will not interfere with the circuit board 40, and the installation is more convenient, thus achieving the effect of avoiding damage to the circuit board 40.

[0037] The first mounting portion 11 can be set as a buckle, or can be set as a connecting portion, or can be set as a connecting flange. The second mounting portion 21 can be correspondingly set as a card slot 22, a connecting portion, or a connecting flange, etc. The buckle can be directly snapped into the card slot 22. For the connecting portion or the connecting flange, holes can be directly drilled on it and fixed with screws. The specific structures of the first mounting portion 11 and the second mounting portion 21 can be set according to actual needs, as long as the first mounting portion 11 and the second mounting portion 21 are overlapped and their connection direction is misaligned with the circuit board 40.

[0038] In an embodiment, as Figure 5 , the overlapping direction of the first mounting portion 11 and the second mounting portion 21 is perpendicular to the board surface direction of the circuit board 40. A first mounting hole 111 is opened on the first mounting portion 11, and a second mounting hole 211 is opened on the second mounting portion 21. The first mounting hole 111 and the second mounting hole 211 are connected by a screw 14. At this time, the tool can be directly used to tighten the screw 14 in the vertical direction, which can well avoid interference with the circuit board 40 and make the installation more convenient.

[0039] By setting the first mounting portion 11 to protrude from the end face of the first housing 10 and the second mounting portion 21 to face the first mounting portion 11, the first mounting portion 11 and the second mounting portion 21 are connected in a direction opposite to each other. That is, by using the space staggered with the circuit board 40, it is possible to avoid collision or interference with the circuit board 40 mounted on the second housing 20 during assembly, improving the feasibility and convenience of assembly and not damaging the circuit board 40.

[0040] In an embodiment of the present utility model, a circuit board 40 is mounted on the second housing 20; a first fixing hole (not shown in the figure) is opened on the first mounting portion 11, and a second fixing hole (not shown in the figure) is opened on the second mounting portion 21. The first fixing hole and the second fixing hole are connected by screws, and the included angle α between the connection direction of the first fixing hole and the second fixing hole and the board surface of the circuit board 40 satisfies 0° < α < 90°.

[0041] It should be noted that the first fixing hole is aligned with the second fixing hole, and the included angle between the connecting direction of the first fixing hole and the second fixing hole and the board surface of the circuit board 40 is set to 0° < α < 90°. During installation, the first fixing hole and the second fixing hole are connected by screws, so that the tool and the screws form an acute angle with the board surface of the circuit board 40. Inclined installation of the screws can also achieve the effects of avoiding damage to the circuit board 40 and facilitating installation. Moreover, this solution enables a wider installation position range for the first installation part 11 and the second installation part 21, which can help make better use of the limited space and optimize space utilization. The first installation part 11 can protrude along the end face or side face of the first housing 10, and the second installation part 21 can also protrude along the end face or side face of the second housing 20, as long as the connecting direction of the two fixing holes forms a preset included angle with the board surface of the circuit board 40.

[0042] In an embodiment of the present invention, a circuit board 40 is installed on the second housing 20, and the first housing 10 is partially sleeved outside the second housing 20; the first installation part 11 includes a first connection hole (not shown in the figure), and the first connection hole is opened on the wall surface of the first housing 10 that coincides with the second housing 20; the second installation part 21 includes a second connection hole (not shown in the figure), and the second connection hole is opened on the wall surface of the second housing 20 that coincides with the first housing 10, and the first connection hole and the second connection hole are connected by screws.

[0043] Specifically, as Figure 3 , the first housing 10 is partially sleeved outside the second housing 20. Therefore, the first connection hole can be directly opened on the first housing 10, and the second connection hole can be opened on the second housing 20. The first housing 10 is directly fixed on the second housing 20 by connecting the first connection hole and the second connection hole with screws, without separately arranging a connecting part, which simplifies the process steps. Moreover, the direct drilling method occupies less space. In the case of limited space inside the housing structure 100, components can be arranged more compactly, improving space utilization.

[0044] In an embodiment of the present invention, the first housing 10 further includes a hook part 12, the hook part 12 protrudes from the end face of the first housing 10, and a card slot 22 is provided on the side wall of the second housing 20, and the hook part 12 is connected to the card slot 22.

[0045] It should be noted that, as Figure 3, a hook portion 12 is further provided on the first housing 10. By cooperating and connecting the hook portion 12 with the card slot 22 of the second housing 20, it can help the first mounting portion 11 and the second mounting portion 21 to be quickly guided to the correct position alignment at the initial stage of installation, reducing the time required for manual alignment, making the assembly process more rapid and simple, improving the assembly efficiency, ensuring the installation accuracy, and improving the assembly precision and consistency of the housing structure 100. At the same time, when disassembly and maintenance are required, the pre-positioning hook portion 12 can ensure that the first housing 10 reaches the same precise position each time it is installed, which is beneficial to equipment maintenance.

[0046] In an embodiment of the present invention, the second housing 20 includes an upper bracket 23 and a lower bracket 24. The upper bracket 23 is snap-connected to the lower bracket 24, and the second mounting portion 21 is provided on the upper bracket 23 and / or the lower bracket 24.

[0047] Specifically, the second housing 20 is designed in a split type. The second housing 20 can be separately disassembled into the upper bracket 23 and the lower bracket 24, and through snap connection, it is convenient for assembling components, facilitating maintenance and repair. And the split bracket design can provide more heat dissipation channels inside the equipment, optimizing heat dissipation and ventilation. Ventilation openings or heat dissipation components can be designed between the upper bracket 23 and the lower bracket 24, which helps to improve the thermal management performance of the system and extend the equipment life.

[0048] The number of the second mounting portions 21 is set according to actual needs, and the position of the second mounting portion 21 can also be set according to actual needs. It can be set on both the upper bracket 23 and the lower bracket 24 at the same time, or only on the upper bracket 23 or the lower bracket 24. In one embodiment, as Figure 2 and Figure 3 , four second mounting portions 21 are provided, and four first mounting portions 11 are also correspondingly provided. The second mounting portions 21 are connected to the first mounting portions 11 in one-to-one correspondence, and the connection is more stable.

[0049] In an embodiment of the present invention, the second housing 20 further includes a front-end bracket 25. The front-end bracket 25 is connected to one end of the upper bracket 23 and the lower bracket 24, and the first housing 10 covers the outside of the front-end bracket 25.

[0050] Specifically, a front-end bracket 25 is further provided between the first housing 10 and the second housing 20. The front-end bracket 25 connects the upper bracket 23 and the lower bracket 24, making the connection between the upper bracket 23 and the lower bracket 24 more stable. In an embodiment, first threaded holes (not shown in the figure) are formed on both the upper bracket 23 and the lower bracket 24, and corresponding second threaded holes (not shown in the figure) are formed on the front-end bracket 25. The first threaded holes and the second threaded holes are connected by screws to fix the front-end bracket 25. By providing the front-end bracket 25, it is possible to support and connect front-end components, such as thermal conductive silicone, FPC induction sheet 70, reflector, sealing ring, etc.

[0051] In an embodiment of the present invention, the housing structure 100 further includes a lens 50. The lens 50 is disposed within the first housing 10. An end of the first housing 10 remote from the second housing 20 is provided with a light-transmitting hole 13, and the light-transmitting hole 13 at least partially coincides with the lens 50; and / or, the housing structure 100 further includes a decorative ring 60. The decorative ring 60 is clamped between the first housing 10 and the housing assembly 30 and at least partially exposed outside the housing assembly 30.

[0052] Specifically, the lens is mounted on the first housing 10 and located between the first housing 10 and the front-end bracket 25. An end of the second housing 20 close to the front-end bracket 25 is connected to a lamp group. The light of the lamp group can be focused through the lens, changing the propagation direction and spot size of the light, so that the light energy can be more concentratedly irradiated onto the treatment area, improving the accuracy and effectiveness of the treatment.

[0053] At the same time, as Figure 4 , a decorative ring 60 is provided between the first housing 10 and the housing assembly 30. The decorative ring 60 can enhance the aesthetic appearance of the light therapy device and can also serve as a seal. By closely fitting to the edges of the first housing 10 and the housing assembly 30 through a stepped surface, it can prevent external environmental factors from penetrating into the interior of the housing structure 100 and maintain the sealing performance of the light therapy device. The decorative ring 60 is located between the first housing 10 and the housing assembly 30 and can also be used as a protective layer to prevent direct contact between the first housing 10 and the housing assembly 30 from causing wear.

[0054] In an embodiment of the present invention, the housing assembly 30 includes an outer shell 31 and a rear shell member 32. The two ends of the outer shell 31 are respectively provided with a first opening 311 and a second opening 312. The second housing 20 is detachably mounted within the outer shell 31. The first housing 10 closes the first opening 311, and the rear shell member 32 is connected to the second opening 312 of the outer shell 31.

[0055] Specifically, as Figure 2The shell assembly 30 is configured as an outer shell 31 and a rear shell 32. The rear shell 32 is disposed at the second opening 312 of the outer shell 31. The second shell 20 is installed in the outer shell 31 and makes the first shell 10 located at the first opening 311 of the outer shell 31. The first shell 10 and the second shell 20 are respectively connected to the two openings of the outer shell 31 to form a complete external shell of the shell structure 100, which plays a protective and supporting role.

[0056] The rear shell component 32 includes a rear shell 321 and a tail cover 322. The rear shell 321 is connected to the end of the second shell 20 that faces away from the first shell 10. The tail cover 322 partially extends into the rear shell 321 and is snap-connected to the rear shell 321. This design can increase the structural strength and stability of the shell assembly 30. A heat dissipation structure is designed between the rear shell 321 and the tail cover 322 to help heat dissipate from the inside, thereby improving the heat dissipation efficiency of the phototherapy device and extending its service life.

[0057] The housing assembly 30 may further be provided with a third housing, a fourth housing, etc. as required to form a multi-layer stacking structure, so as to integrate more electronic components and functions in a limited space.
