Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments.

[0043] In the description of the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Exactly speaking, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific manner.

[0044] The present application first provides a light guide column, which has the technical effects of being convenient to install, improving the assembly efficiency and production efficiency.

[0045] Please refer to Figure 1 and Figure 2, the light guide column 100 can be applied to an inverter device. The inverter device includes a fixed structure 200, a light-emitting element 300, and the light guide column 100. Among them, the fixed structure 200 is provided with a mounting hole 201, the light guide column 100 passes through the mounting hole 201, the light guide column 100 is fixed to the fixed structure 200 and is hermetically connected to the fixed structure 200, and one end of the light guide column 100 is arranged to face the light-emitting element 300. The fixed structure 200 can be the housing of the inverter device or a fixing plate installed inside the housing. Taking the fixed structure 200 as the housing as an example, the light-emitting element 300 can be a lamp bead installed inside the housing.

[0046] The light guide column 100 includes a main body and a sealing ring 50. Among them, the main body includes a sealing portion 10, a display portion 20, a light-receiving portion 30, and a buckle member 40. Among them, the sealing portion 10 is integrally cylindrical, and the sealing portion 10 extends along the first direction (i.e., the X-axis direction in the figure).

[0047] The display portion 20 is arranged at one end of the sealing portion 10, and positioning blocks 21 are arranged on the circumferential side of the display portion 20. The light-receiving portion 30 is arranged at the other end of the sealing portion 10, the buckle member 40 is arranged on the circumferential side of the light-receiving portion 30, and the buckle member 40 has a deformation ability. The display portion 20 and the buckle member 40 are respectively located at both ends of the sealing portion 10 in the first direction, so that the buckle member 40 and the positioning blocks 21 are spaced apart along the first direction, and a clamping space is formed between the buckle member 40 and the positioning blocks 21.

[0048] The sealing ring 50 is sleeved on the sealing portion 10, the sealing ring 50 is distributed along the circumferential side of the sealing portion 10, and the sealing ring 50 is located between the buckle member 40 and the positioning blocks 21.

[0049] When the light guide column 100 is installed on the fixed structure 200, the sealing portion 10 passes through the mounting hole 201, the sealing ring 50 can fill the gap between the sealing portion 10 and the inner wall of the mounting hole 201 to seal the sealing portion 10 and the fixed structure 200, and the positioning blocks 21 and the buckle member 40 can abut against both sides of the fixed structure 200 in the first direction, so that the fixed structure 200 can be clamped in the clamping space.

[0050] In the example of this embodiment, the fixed structure 200 is arranged parallel to the second direction (i.e., the Y-axis direction in the figure), and the fixed structure 200 is provided with a mounting hole 201 along the first direction.

[0051] When the light guide column 100 is installed on the fixed structure 200, the light-receiving part 30 of the light guide column 100 is arranged opposite to the light-emitting element 300, and the display part 20 of the light guide column 100 is exposed outside the fixed structure 200. In this way, when the light-emitting element 300 emits light, the light can sequentially pass through the light-receiving part 30, the sealing part 10 and be conducted to the display part 20, thus realizing the function of the indicator light. At the same time, the sealing ring 50 of the light guide column 100 can seal the gap between the fixed structure 200 and the light guide column 100, achieving a sealing effect, preventing pollutants such as particulate matter and moisture from entering, protecting the components inside the fixed structure 200, and improving the working stability and service life of the equipment.

[0052] Specifically, the installation method of the light guide column 100 can be as follows: First, the sealing ring 50 is sleeved on the sealing part 10; then, the light-receiving part 30 is inserted into the installation hole 201, and force is applied along the insertion direction. In this way, the buckle 40 deforms and forms an interference fit with the fixed structure 200, so that the sealing part 10 and the sealing ring 50 will enter the installation hole 201. Then, the buckle 40 resumes deformation, and the buckle 40 and the positioning block 21 cooperate to clamp the fixed structure 200 to complete the installation of the light guide column 100. The above installation method is simple and fast, improving the assembly efficiency and production capacity.

[0053] In one application scenario, when the fixed structure 200 is clamped between the buckle 40 and the positioning block 21 through the above installation method, the installation of the light guide column 100 can be completed. In this way, a detachable connection is realized between the fixed structure 200 and the light guide column 100, which is convenient for the disassembly and maintenance of the light guide column 100 in the later stage.

[0054] In another application scenario, the above installation method can also be used as a preliminary installation step, that is, after the fixed structure 200 is clamped between the buckle 40 and the positioning block 21, sealant can be poured between the fixed structure 200 and the light guide column 100 to further improve the sealing performance and installation stability.

[0055] In some embodiments, the light guide column 100 is integrally formed by PC plastic (Polycarbonate), that is, the sealing part 10, the display part 20, the light-receiving part 30 and the buckle 40 are integrally connected. The processing technology is simple, the installation steps are omitted, and the light guide column 100 itself has a certain deformation ability, so that the buckle 40 can deform and resume deformation under reasonable force.

[0056] In some embodiments, the display part 20 extends axially along the sealing part 10 as a whole. The display part 20 protrudes radially outward along the sealing part 10 to form a positioning block 21. In this way, the radius of the display part 20 is greater than the radius of the sealing part 10, and the part of the display part 20 protruding from the circumferential side of the sealing part 10 forms a positioning block 21, so that the positioning blocks 21 are distributed circumferentially along the sealing part 10.

[0057] Please refer to Figure 2 and Figure 3 In some embodiments, a positioning surface 22 is provided on a surface of the positioning block 21 facing the buckle member 40, and the positioning surface 22 is arranged parallel to the second direction. When the positioning block 21 abuts against the fixing structure 200, the positioning block 21 contacts the fixing structure 200 through the positioning surface 22. Since the positioning surface 22 is parallel to the surface of the fixing structure 200, the contact area between the display portion 20 and the fixing structure 200 can be increased, the stress effect can be improved, and the installation stability can be enhanced.

[0058] Please refer to Figure 1 and Figure 2 In some embodiments, the sealing ring 50 is in an annular shape, and the sealing ring 50 can be made of elastic materials such as rubber and silica gel.

[0059] In some embodiments, a sealing groove 11 is provided on the circumferential side of the sealing portion 10. The groove width of the sealing groove 11 is adapted to the cross-sectional diameter of the sealing ring 50, and the groove depth of the sealing groove 11 is less than the cross-sectional diameter of the sealing ring 50.

[0060] Thus, when the sealing ring 50 is disposed in the sealing groove 11, the sealing ring 50 is partially received in the sealing groove 11. Among them, the inner ring portion of the sealing ring 50 is clamped in the sealing groove 11 to prevent the sealing ring 50 from deviating from the sealing portion 10, while the outer ring portion of the sealing ring 50 can be exposed outside the sealing groove 11 to contact the hole wall of the mounting hole 201 to achieve a sealing effect.

[0061] When it is necessary to sleeved the sealing ring 50 on the sealing portion 10, the sealing ring 50 can be first sleeved on one end of the light receiving portion 30 away from the sealing portion 10, and the sealing ring 50 is moved towards the sealing portion 10, so that the sealing ring 50 passes through the buckle member 40 to reach the sealing portion 10 and is clamped in the sealing groove 11.

[0062] Please refer to Figure 2 and Figure 3 In some embodiments, the light receiving portion 30 extends integrally along the axial direction of the sealing portion 10, and a concave groove 31 is provided at one end of the light receiving portion 30 away from the sealing portion 10. The concave groove 31 is circularly recessed in a direction close to the sealing portion 10, and the concave groove 31 can receive the light emitting element 300 and gather the light emitted by the light emitting element 300.

[0063] In some embodiments, the buckle member 40 is disposed obliquely with respect to the light-receiving portion 30 as a whole, that is, there is an included angle between the buckle member 40 as a whole and the first direction. A plurality of buckle members 40 are provided, and the plurality of buckle members 40 are spaced apart around the light-receiving portion 30. Exemplarily, the number of the buckle members 40 is 2, and the two buckle members 40 are symmetrically distributed along the axis of the light-receiving portion 30. When the buckle members 40 and the positioning block 21 cooperate to abut against both sides of the fixing structure 200, the plurality of buckle members 40 can increase the contact area with the fixing structure 200, thereby improving the fixing stability.

[0064] Please refer to Figure 1 and Figure 2 , in some embodiments, the buckle member 40 has a first end 41 and a second end 42. Among them, the first end 41 and the second end 42 are distributed in the first direction. The first end 41 is fixed to the light-receiving portion 30, the second end 42 is disposed toward the positioning block 21, and there is a distance between the second end 42 and the light-receiving portion 30.

[0065] The buckle member 40 has an original state and a deformed state. Among them, the original state refers to the state of the buckle member 40 when it is not deformed by force. At this time, the maximum distance from the second end 42 of the buckle member 40 to the axis of the light-receiving portion 30 is greater than the hole radius of the mounting hole 201, so that the buckle member 40 cannot pass through the mounting hole 201.

[0066] The deformed state refers to the state of the buckle member 40 after being deformed by force. At this time, the second end 42 of the buckle member 40 moves toward the direction closer to the light-receiving portion 30, so that the maximum distance from the second end 42 of the buckle member 40 to the axis of the light-receiving portion 30 is less than or equal to the hole radius of the mounting hole 201, so that the buckle member 40 can pass through the mounting hole 201, and when the buckle member 40 is not stressed, the buckle member 40 will return to the original state after recovering from the deformation.

[0067] During the installation process of the light guide column 100, the light guide column 100 is first in the original state. At this time, a force can be applied to the buckle member 40 to switch the buckle member 40 to the deformed state, and then the buckle member 40 and the light-receiving portion 30 are passed through the mounting hole 201, and then a force is applied to the buckle member 40 in contact, so that the buckle member 40 automatically pops out and returns to the original state, completing the installation of the light guide column 100.

[0068] Please refer to Figure 2 and Figure 4 , in some embodiments, a guiding surface 43 is provided on the surface of the buckle member 40 away from the light-receiving portion 30, and the guiding surface 43 is inclined away from the light-receiving portion 30 from the first end 41 to the second end 42.

[0069] During the installation process of the light guide column 100, when the light guide column 100 moves towards the direction of being inserted into the installation hole 201, the hole wall of the installation hole 201 will abut against the guiding surface 43, generating a force to squeeze the buckle 40, causing the buckle 40 to gradually deform from its original state. In this way, it is not necessary for the user to manually apply an additional force to squeeze the buckle 40, facilitating the installation of the light guide column 100.

[0070] In some embodiments, the guiding surface 43 is a curved surface, and the inclination angle formed between the guiding surface 43 and the first direction gradually decreases towards the direction closer to the second end 42. In this way, after the light receiving part 30 and the buckle 40 have entered the installation hole 201, the degree of extrusion of the hole wall of the installation hole 201 on the buckle 40 can be reduced, and the risk of the buckle 40 breaking due to excessive force can be reduced.

[0071] In some embodiments, a contact surface 44 is provided on the surface of the second end 42 facing the positioning block 21, and the contact surface 44 is arranged parallel to the second direction. When the buckle 40 abuts against the fixing structure 200, the second end 42 contacts the fixing structure 200 through the contact surface 44. Since the contact surface 44 is parallel to the surface of the fixing structure 200, the contact area between the buckle 40 and the fixing structure 200 can be increased, improving the force receiving effect and enhancing the installation stability.

[0072] In some embodiments, there is a gap between the second end 42 and the sealing part 10, and the width of this gap is smaller than the cross-sectional diameter of the sealing ring 50. That is, the distance between the second end 42 and the sealing part 10 in the first direction is smaller than the width of the sealing ring 50 in the first direction.

[0073] In this way, during the process of sleeving the sealing ring 50 on the sealing part 10, when the sealing ring 50 passes through the buckle 40 and reaches the sealing part 10, it can be avoided that the sealing ring 50 shrinks inward and gets stuck in the gap between the second end 42 and the sealing part 10, improving the installation efficiency of the sealing ring 50.

[0074] In some embodiments, a relief groove 32 is provided on the circumferential side of the light receiving part 30, and the position of the relief groove 32 is correspondingly arranged with the buckle 40. Exemplarily, the number of relief grooves 32 is 2, and the two relief grooves 32 are respectively distributed corresponding to the second ends 42 of the two buckles 40.

[0075] It can be understood that the relief groove 32 leaves a certain space for the second end 42 of the buckle 40, so that there is a gap between the second end 42 and the light receiving part 30. And by providing the relief groove 32 on the side of the light receiving part 30 to leave enough displacement space for the second end 42, the thickness requirement for the second end 42 can be reduced, so that the buckle 40 as a whole can retain a larger thickness, in order to improve the mechanical strength of the buckle 40 itself and the connection strength with the light receiving part 30, and reduce the risk of the buckle 40 breaking after being deformed by force.

[0076] In some embodiments, the relief groove 32 has a first groove wall 321 and a second groove wall 322 in a first direction. Among them, the first groove wall 321 is connected to the first end 41, the second groove wall 322 faces the second end 42, and a chamfer surface 323 is provided on one side of the second groove wall 322 close to the groove opening. When the buckle 40 deforms, the middle part and the second end 42 of the buckle 40 can both bend in the direction of entering the relief groove 32, and the chamfer surface 323 avoids interference between the second end 42 and the second groove wall 322. In this way, on the basis of ensuring the connection strength between the buckle 40 and the light-receiving part 30, the buckle 40 is more likely to deform, improving the installation efficiency.

[0077] Please refer to Figure 1 and Figure 2 , the present application also provides an inverter device. The inverter device includes a light guide column 100, a fixing structure 200, and a light-emitting element 300. Among them, the fixing structure 200 is a housing, the housing is provided with a mounting hole 201, the light-emitting element 300 is arranged on a circuit board, and the circuit board is fixed inside the housing. The light guide column 100 passes through the mounting hole 201, the light guide column 100 is fixed to the housing and is hermetically connected to the housing, and one end of the light guide column 100 is aligned with the light-emitting element 300.

[0078] For the implementation principle and beneficial effects of the inverter device provided by the embodiments of the present application, specifically, reference can be made to the relevant description of the light guide column 100 in the foregoing embodiments, and the present application will not elaborate herein.

[0079] For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present application, the present application can be implemented in other specific forms. Therefore, from any point of view, the above embodiments of the present application should be regarded as exemplary and non-limiting.
