Furthermore, existing light guide structures lack effective positioning measures during installation, making accurate alignment difficult, resulting in low installation efficiency, and also failing to guarantee the stability of the connection between the light guide and the electrical equipment.

[0029] Please see Figure 1-5This utility model provides a light guide column structure 1, which is applied to an electrical device 2. It includes a light guide column array 11, which includes at least two rows of light guide columns 12 connected in sequence. Each row of light guide columns 12 is provided with at least one light guide column 12. The light guide column 12 includes a light guide column body 121 and an input end 122 and an output end 123 respectively provided at both ends of the light guide column body 121. The output end 123 is connected to the electrical device 2. The light guide column array 11 also includes a limiting member 13 that is limited and connected to the electrical device 2. The limiting member 13 is used to limit the light guide column structure 1 when it is installed on the electrical device 2.
[0030] In this embodiment, the light guide column array 11 includes at least two rows of parallel and sequentially connected light guide columns 12. Each row of light guide columns 12 has at least one light guide column 12, and the specific number can be adjusted according to the number of indicator lights of the electrical device 2. In the light guide column 12, each light guide column body 121 can be made of transparent PC (polycarbonate) or PMMA (acrylic) material, and the surface can be frosted to enhance the diffuse reflection effect of light. The end face of the light input end 122 can be set as a planar structure to fit closely to the light source inside the electrical device 2, so as to facilitate the transmission of all light to the indicator position. A prism array or phosphor can be added inside the light guide column body 121 to enhance the light collection and refraction efficiency. The end face of the light output end 123 can be set as a hemispherical convex structure and connected to the housing of the electrical device 2. A frosted layer can also be covered on the surface of the light output end 123 to achieve diffuse reflection, so that the light received by the light input end 122 is uniformly diffused from the light output end 123 through the housing of the electrical device 2 to the indicator area outside the electrical device 2.
[0031] The light guide column array 11 is also provided with a limiting member 13, which can be limited by the limiting connection with the electrical equipment 2. The installation process of the entire light guide column structure 1 is as follows: the light input end 122 of the light guide column array 11 is aligned with the light source inside the electrical equipment 2, and the light output end 123 is connected to the housing of the electrical equipment 2, so that the light output end 123 is aligned with the indicator outlet of the electrical equipment 2 (the indicator outlet is usually set on the housing of the electrical equipment 2). The limiting member 13 is installed on the electrical equipment 2 to achieve the limiting connection. Through the connection between the light output end 123 and the limiting member 13 and the electrical equipment 2, dual limiting in the horizontal and vertical directions is achieved to prevent the light guide column 12 from shifting due to vibration or other factors.
[0032] In practical implementation, the limiting component 13 can be made of high-strength, corrosion-resistant alloy material, and its surface can be treated with anti-slip coating to improve installation stability. In addition, the light guide column array 11 can be made in one piece to reduce light loss at the connection between adjacent rows of light guide columns 12 and improve light guiding efficiency.
[0033] This embodiment uses at least two rows of sequentially connected light guide columns 12 to form a light guide column array 11, enabling concentrated transmission and efficient guidance of light. The limiting member 13 ensures the accuracy and stability of the light guide column structure 1 on the electrical equipment 2, preventing displacement. The working process of the light guide column structure 1 is as follows: the light input end 122 receives light emitted from the light source and enters the light guide column body 121. After passing through the interior of the light guide column body 121, the light is finally transmitted from the light output end 123 to the designated position on the electrical equipment 2 for display. The light guide column structure 1 improves light transmission efficiency, ensures stable installation of the light guide columns 12 on the electrical equipment 2, and reduces light leakage. The number of rows in the light guide column array 11 and the number of light guide columns 12 in each row can be adjusted according to the space requirements and light display requirements of different electrical equipment 2.
[0034] Specifically, such as Figure 1 As shown, the light-inlet end 122 is bent and extended, the light-outlet end 123 is extended in a straight line, and the limiting member 13 is vertically arranged on the light guide column body 121.
[0035] In this embodiment, setting the light-incident end 122 as a bent extension allows the light guide column 12 to better adapt to light sources at different positions and angles, increasing the coupling efficiency of light entering the light guide column 12, reducing light reflection and scattering losses at the light-incident end 122, thereby improving the light transmission efficiency and enabling the light-exit end 123 to obtain more light. Setting the light-exit end 123 as a straight extension allows the light to be emitted in a more concentrated direction, improving light utilization and output effect. The limiting member 13, vertically set on the light guide column body 121, ensures the accurate position of the light guide column 12 during installation, avoiding light transmission problems caused by installation deviations, while also enhancing the stability of the light guide column 12 in the electrical equipment 2, preventing displacement due to vibration or external forces, and ensuring the normal operation of the light guide column structure 1.
[0036] In practical implementation, to further improve the adaptability of the light guide post 12 to different light sources, the bending extension of the light input end 122 can be designed as an adjustable structure. That is, a flexible material or a rotatable joint structure can be used to allow the bending angle and direction of the light input end 122 to be flexibly adjusted according to the actual position of the light source. In this way, when changing the light source or adjusting the layout of the electrical equipment 2, there is no need to replace the light guide post 12; only the light input end 122 needs to be adjusted, thus improving the versatility and flexibility of the light guide post 12.
[0037] Specifically, such as Figure 1 As shown, the light-incident ends 122 of different rows of light guide columns 12 are arranged alternately.
[0038] In this embodiment, to improve the light guiding efficiency of the light guide columns 12, it is preferable to stagger the light-incident ends 122 of different rows of light guide columns 12, allowing light to enter the light guide columns 12 from multiple different positions and angles. Furthermore, because the light-incident ends 122 of each row of light guide columns 12 are staggered, light entering the light guide columns 12 can more effectively avoid mutual obstruction and interference, reducing light loss. Compared to a linear arrangement, this layout avoids the phenomenon of excessively strong or weak light in local areas, thereby achieving a more uniform light distribution throughout the entire illumination area. During the operation of the light guide columns 12, the staggered light-incident ends 122 can receive light emitted from the light source from all directions, improving light collection efficiency.
[0039] In practical implementation, the staggered spacing and angle can be planned according to the distribution of light sources. In this embodiment, the staggering is set as follows: adjacent light-incident ends 122 are staggered. For ease of explanation, it is referred to as... Figure 1 Taking the direction in the middle as an example, the foremost light guide post 12 is designated as the first light guide post 12. In the order of sequential connection, the light guide posts 12 are designated as the second light guide post 12, the third light guide post 12, the fourth light guide post 12, and so on. The first light guide post 12 is designated as a light guide post 12 of the first length, the second light guide post 12 is designated as a light guide post 12 of the second length, and the third light guide post 12 is designated as a light guide post 12 of the first length, the fourth light guide post 12 is designated as a light guide post 12 of the second length, and so on. The first length is less than the second length. In this way, after the light-incident end 122 is bent and extended, the light-incident end 122 of the light guide post 12 of the first length and the light-incident end 122 of the light guide post 12 of the second length are not in the same row, thereby realizing the staggered light-incident ends 122 of different rows of light guide posts 12.
[0040] Specifically, such as Figure 1 As shown, the light-emitting ends 123 of different rows of light guide columns 12 are arranged in parallel.
[0041] In this embodiment, in order to ensure that the light output direction of all light guide columns 12 is consistent, it is preferable to set the light output ends 123 of different rows of light guide columns 12 in parallel. The parallel light output ends 123 can concentrate the light onto the same area of the electrical equipment 2 to form a uniform display effect.
[0042] Specifically, such as Figure 1 As shown, the cross-sectional area of the light-incident end 122 decreases; or, the cross-sectional area of the light-exit end 123 is smaller than that of the light-incident end 122.
[0043] In this embodiment, when the cross-sectional area of the light-incident end 122 decreases, the light is compressed as it enters the light guide column body 121 due to the gradually decreasing cross-sectional area, thereby converging the light and reducing scattering loss during transmission. Similarly, setting the cross-sectional area of the light-exiting end 123 to be smaller than that of the light-incident end 122 also enables the light to be concentrated and emitted at the light-exiting end 123 after transmission inside the light guide column body 121, increasing the emission intensity. This design of varying cross-sectional area optimizes the total internal reflection path of the light in the light guide column body 121, reduces the possibility of light leakage, and ensures efficient and stable transmission of light to the designated location of the electrical device 2.
[0044] In practical operation, the light emitted from the light source enters the light-inlet end 122 from the end with the larger cross-sectional area. As the light propagates through the gradually narrowing light-inlet end 122, it is continuously focused and then enters the light guide column body 121 for total internal reflection. When the light reaches the light-outlet end 123, because the cross-sectional area of the light-outlet end 123 is smaller than that of the light-inlet end 122, the light is further concentrated and emitted at a higher intensity to the display area of the electrical device 2. If only the cross-sectional area of the light-outlet end 123 is smaller than that of the light-inlet end 122, the light remains relatively stable during its internal transmission after entering the light guide column body 121 from the light-inlet end 122 until it reaches the light-outlet end 123. Due to the smaller cross-sectional area, the light is compressed and concentrated, thus achieving efficient emission.
[0045] In a specific implementation, the light-emitting end 123 includes a connecting part 1231 and a light-emitting part 1232 connected in sequence. The connecting part 1231 is configured as a trapezoidal body structure with a decreasing cross-sectional area. The light-emitting part 1232 is connected to the decreasing side of the connecting part 1231, so that the cross-sectional area of the light guide column body 121 and the light-emitting end 123 decreases in a step-like manner, so that the light-emitting part 1232 meets the display spacing requirements of the electrical equipment.
[0046] Specifically, at least two limiting members 13 are spaced apart and located on the same side of the light guide structure 1.
[0047] In this embodiment, at least two spaced limiting members 13 are arranged at intervals to form a stable limiting constraint, preventing the light guide column structure 1 from shifting or rotating during installation. During operation, the multiple spaced limiting members 13 cooperate with the limiting structure on the electrical equipment 2 (i.e., the limiting post 22 in the subsequent embodiment) to stably limit the light guide column structure 1 from the same side. This embodiment improves the stability and reliability of the installation of the light guide column structure 1. In specific implementation, the number and spacing of the limiting members 13 can be determined according to the size and weight of the light guide column structure 1.
[0048] Specifically, such as Figure 1As shown, the limiting member 13 is disposed between two adjacent rows of light guide columns 12.
[0049] In this embodiment, to ensure the limiting effect of the limiting member 13 without affecting the light transmission of the light guide column 12, the limiting member 13 is preferably placed between two adjacent rows of light guide columns 12, that is, at the connection point of two adjacent rows of light guide columns 12. During assembly, the limiting member 13 cooperates with the limiting structure on the electrical equipment 2 to limit and fix the light guide column array 11, so as to achieve stable installation without interfering with the light transmission. Among them, the limiting member 13 is a columnar limiting member 13. In specific implementation, other limiting members 13 of different shapes and sizes can be designed according to the layout of the light guide column array 11, such as rhomboid limiting members 13 or conical limiting members 13. Multiple different types of limiting members 13 can be combined between two adjacent rows of light guide columns 12 to improve the reliability of the limiting.
[0050] Specifically, such as Figure 1 As shown, a mounting hole 14 is provided on at least one side of the light guide column array 11, and the mounting hole 14 is used for mounting the light guide column structure 1 onto the electrical equipment 2.
[0051] In this embodiment, a mounting portion is provided extending outward from the side of the light guide column array 11. The mounting hole 14 is provided on the mounting portion. The mounting hole 14 cooperates with the mounting structure on the electrical device 2 (the mounting column 24 in subsequent embodiments) to achieve rapid installation of the light guide column structure 1. To save assembly space, only one mounting hole 14 is needed in this embodiment. In specific implementations, different numbers and distributions of mounting holes 14 can be designed according to the installation requirements of the electrical device 2. This embodiment improves installation efficiency and ensures the accuracy of the installation position by providing mounting holes 14 on the light guide column array 11.
[0052] like Figure 2-5 As shown, this utility model embodiment also provides an electrical device 2, which includes the light guide column structure 1 as described above.
[0053] By adopting the light guide column structure 1 of the above embodiment, the electrical device 2 can achieve efficient light transmission and stable display effect, thereby improving the overall performance and reliability of the electrical device 2.
[0054] Specifically, such as Figure 2-5 As shown, the electrical equipment 2 is provided with a limiting post 22 and a connecting hole 23. The limiting post 22 is provided with a limiting hole 221. The limiting member 13 is inserted into the limiting hole 221, and the light-emitting end 123 is connected to the connecting hole 23.
[0055] In this embodiment, to facilitate the installation of the electrical equipment 2 and the light guide column structure 1, the electrical equipment 2 has an installation space 21 for installing the light guide column structure 1. The installation space 21 is located near the corner of the housing. A limiting post 22 is disposed within the installation space 21, and a connecting hole 23 is disposed on the housing. The connecting hole 23 can be a through hole or a blind hole. The number of limiting posts 22 corresponds to the number of limiting members 13. In the aforementioned embodiment, at least two limiting members 13 are provided; therefore, at least two limiting posts 22 should also be provided. Each limiting post 22 also has a limiting hole 221. The assembly process of the light guide column structure 1 and the electrical equipment 2 is as follows: the light-emitting end 123 of the light guide column structure 1 is aligned with the connecting hole 23 for connection, and the limiting member 13 of the light guide column structure 1 is inserted into the limiting hole 221. Through the precise cooperation of the limiting post 22 and the connecting hole 23 with the limiting member 13 and the light-emitting end 123 on the light guide column structure 1, stable installation and light transmission of the light guide column structure 1 are achieved.
[0056] In practical implementation, in order to achieve a stable connection between the limiting member 13 and the limiting post 22, an internal thread can be provided in the limiting hole 221 and an external thread can be provided on the limiting member 13, so as to achieve a fastening connection through the internal thread and the external thread.
[0057] Specifically, such as Figure 2-5 As shown, the electrical equipment 2 also includes a mounting post 24, which is inserted into the mounting hole 14. The mounting post 24 and the limiting post 22 are on the same side of the electrical equipment 2.
[0058] In this embodiment, the installation space 21 of the electrical equipment 2 is also provided with a mounting post 24. The mounting post 24 includes a mounting post 24 body and a limiting part. The limiting part is arranged around the mounting post 24 body, such that the bottom dimension of the mounting post 24 body is larger than the top dimension of the mounting post 24 body. The top of the mounting post 24 body is inserted into the mounting hole 14. Due to the limiting part, the light guide column structure 1 does not contact the bottom of the housing. Moreover, the mounting post 24 and the limiting post 22 are arranged on the same side of the installation space 21, which can achieve double fixation of the light guide column structure 1 and improve installation stability. In specific implementation, if two limiting members 13 are provided, two limiting posts 22 are provided accordingly, and multiple limiting parts are provided, which are arranged in a circumferential array and connected around the mounting post 24 body. The mounting post 24 is connected to the limiting post 22 away from the housing. More specifically, the height of the limiting part is set to be the same as the height of the limiting post 22, and one limiting part close to the limiting post 22 is in contact with the limiting post 22. Anti-slip textures can also be added to the mounting post 24 to increase installation stability. By setting the mounting post 24, the robustness and reliability of the light guide post structure 1 on the electrical equipment 2 are enhanced.
[0059] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
