[0041] Furthermore, by distributing the light guide column 1 and the light source component 2 opposite to each other along the light guiding direction of the light guide mounting cavity 31, the light from the light source component 2 can be directly irradiated toward the inside of the light guide mounting cavity 31, that is, toward the position where the light guide column 1 is located, so that as much light from the light source component 2 as possible can enter the light guide column 1, thereby improving the light utilization rate and facilitating the control of the light propagation direction.

[0042] Therefore, by arranging a light source component 2 in the light guiding structure 100 to provide light, arranging a light guiding column 1 to guide the light emitted by the light source component 2, the light source component 2 and the light guiding column 1 are respectively connected to the two ends of the rubber sleeve 3, so that the light source component 2 and the light guiding column 1 are connected through the rubber sleeve 3, which is convenient for using the light guiding column 1 to guide light, and a light guiding installation cavity 31 is formed inside the rubber sleeve 3, so that the light emitting end of the light source component 2 and the end of the light guiding column 1 connected to the rubber sleeve 3 are both extended into the light guiding installation cavity 31 and connected to the rubber sleeve 3, which can increase the connection and matching length between the light source component 2 and the light guiding column 1 and the rubber sleeve 3, and the light source component 2 and the light guiding column 1 are distributed opposite to each other along the light guiding direction of the light guiding installation cavity 31, which can reduce the loss of light during transmission and facilitate the control of the propagation direction of light.

[0043] According to the light-guiding structure 100 of the embodiment of the utility model, a rubber sleeve 3 is provided, and the two ends of the rubber sleeve 3 are respectively connected to the light source component 2 and the light guide column 1 to realize the connection between the light source component 2 and the light guide column 1, and a light-guiding installation cavity 31 is formed in the rubber sleeve 3, so that the light-emitting end of the light source component 2 and one end of the light guide column 1 are both extended into the light-guiding installation cavity 31 and connected to the rubber sleeve 3, which can improve the connection reliability between the light source component 2 and the light guide column 1, and make the light source component 2 and the light guide column 1 face each other in the light-guiding direction in the light-guiding installation cavity 31, which can reduce the loss of light in the transmission process, improve the light utilization rate, and facilitate the control of the propagation direction of light.

[0044] In some embodiments, one of the outer wall of the light guide column 1 and the inner wall of the rubber sleeve 3 is provided with a limiting recess 36 and the other is provided with a limiting protrusion 15. The limiting protrusion 15 and the limiting recess 36 are inserted in the radial direction of the rubber sleeve 3 and are limited in the axial direction.

[0045] Specifically, one end of the light guide column 1 extends into the rubber sleeve 3 and is connected to the rubber sleeve 3. A limiting recess 36 can be set on the outer peripheral wall of the light guide column 1, and a limiting protrusion 15 can be set on the inner peripheral wall of the rubber sleeve 3. Alternatively, a limiting protrusion 15 can be set on the outer peripheral wall of the light guide column 1, and a limiting recess 36 can be set on the inner peripheral wall of the rubber sleeve 3, so as to realize the connection between the light guide column 1 and the rubber sleeve 3 through the plug-in cooperation of the limiting recess 36 and the limiting protrusion 15.

[0046] Among them, the extension directions of the limiting recess 36 and the limiting convex portion 15 are respectively coincident with the radial lines, so that the limiting recess 36 and the limiting convex portion 15 can be plugged and matched along the radial direction of the rubber sleeve 3, and the light guide column 1 is connected to the rubber sleeve 3 through the cooperation between the limiting recess 36 and the limiting convex portion 15, and the light guide column 1 can be axially limited to ensure the accuracy of the connection position between the two, avoid the part of the light guide column 1 extending into the rubber sleeve 3 is too long or too short, increase the loss of light in the propagation process or affect the light guiding effect, and the two can be relatively fixed in the axial direction to avoid the light guiding effect being affected by the axial movement of the light guide column 1.

[0047] In such Figure 6-10 In the illustrated embodiment, a limiting protrusion 15 is provided on the outer peripheral wall of the light guide column 1, and the limiting protrusion 15 extends outward from the outer peripheral wall of the light guide column 1. A limiting recess 36 is provided on the inner peripheral wall of the rubber sleeve 3, and the limiting recess 36 is recessed inward from the outer peripheral wall of the rubber sleeve 3, so as to realize a limiting connection between the light guide column 1 and the rubber sleeve 3 through the cooperation between the limiting protrusion 15 and the limiting recess 36.

[0048] In some embodiments, the light guide column 1 includes an installation section 11 and a connecting section 12 connected along the light guiding direction, the connecting section 12 extends into the light guide installation cavity 31, the installation section 11 is located outside the light guide installation cavity 31 and has a stop limit surface 111 formed on the end face that cooperates with the end face limit of the rubber sleeve 3.

[0049] Specifically, Figure 3 and Figure 7-Figure 8 As shown, the light guide column 1 includes two parts, namely, a mounting section 11 and a connecting section 12. The connecting section 12 is used to connect with the rubber sleeve 3, and the mounting section 11 is used to limit the rubber sleeve 3. The mounting section 11 and the connecting section 12 are connected to make the light guide column 1 a whole, which is beneficial to improve the overall structural strength of the light guide column 1 and make the light guide column 1 not easy to deform and fail. The connecting section 12 of the light guide column 1 is extended into the light guide installation cavity 31 to cooperate with the rubber sleeve 3 to realize the connection between the light guide column 1 and the rubber sleeve 3. And the connection length between the two can be increased to improve the connection reliability between the two. At the same time, a stop limit surface 111 is formed on the end face of the installation section 11 facing the rubber sleeve 3. The stop limit surface 111 is limited and matched with the end face of the rubber sleeve 3 to further limit the installation position of the light guide column 1, effectively avoiding that the part of the light guide column 1 extending into the rubber sleeve 3 is too long or too short, resulting in increased light loss during propagation or affecting the light guiding effect, and a sealed state can be formed in the light guide installation cavity 31.

[0050] In some embodiments, the outer peripheral wall of the connecting section 12 is formed with a plurality of limiting step surfaces 121 , and the inner peripheral wall of the rubber sleeve 3 is formed with a plurality of matching step surfaces 311 , and the plurality of limiting step surfaces 121 fits with the plurality of matching step surfaces 311 in a one-to-one correspondence.

[0051] Specifically, a limiting step surface 121 is formed on the outer peripheral wall of the connecting section 12, and a matching step surface 311 is formed on the inner peripheral wall of the rubber sleeve 3, so that the connecting section 12 is limited by the cooperation between the limiting step surface 121 and the matching step surface 311, that is, the light guide column 1 is limited to ensure the accuracy of the installation position of the light guide column 1. At the same time, a plurality of limiting step surfaces 121 and matching step surfaces 311 can be provided to effectively improve the limiting effect of the light guide column 1, and the limiting step surface 121 and the matching step surface 311 can be fitted one by one, that is, each limiting step surface 121 has a matching step surface 311 to cooperate with it, and each limiting step surface 121 can be tightly connected with the corresponding matching step surface 311, so as to achieve precise positioning of the light guide column 1, and also to prevent external glue from flowing from the gap between the limiting step surface 121 and the matching step surface 311 to between the light guide column 1 and the light source component 2, thereby affecting the light guiding effect.

[0052] Therefore, when connecting the light guide column 1 and the rubber sleeve 3, not only the stop limit surface 111 and the end surface of the rubber sleeve 3 can be limited, but also the limit step surface 121 and the matching step surface 311 can be limited, which can effectively improve the effect of limiting the light guide column 1 and ensure the accuracy of the connection position between the light guide column 1 and the rubber sleeve 3.

[0053] In some embodiments, the light guide column 1 and the rubber sleeve 3 are interference fit. The light guide column 1 and the rubber sleeve 3 are connected by interference fit, so that a tight connection between the light guide column 1 and the rubber sleeve 3 can be achieved to prevent the external glue from flowing from the gap between the light guide column 1 and the rubber sleeve 3 to the gap between the light guide column 1 and the light source 2, thereby affecting the light guiding effect, and the connection strength and reliability between the light guide column 1 and the rubber sleeve 3 can be improved.

[0054] And / or, the light source component 2 and the rubber sleeve 3 are interference fit. The light source component 2 and the rubber sleeve 3 can also be connected by interference fit to achieve a tight connection between the light source component 2 and the rubber sleeve 3, to prevent the external glue from flowing from the gap between the light guide column 1 and the rubber sleeve 3 to the gap between the light guide column 1 and the light source component 2, thereby affecting the light guide effect, and to improve the connection strength and reliability between the light source component 2 and the rubber sleeve 3.

[0055] Therefore, by making the light guide column 1 and the rubber sleeve 3 tightly connected, and making the light source component 2 and the rubber sleeve 3 tightly connected, the connection reliability between the light guide column 1 and the light source component 2 can be improved, and the external glue can be effectively prevented from flowing between the light guide column 1 and the light source component 2 to affect the light guiding effect.

[0056] And / or, a light guiding groove 13 is formed on an end surface of the light guiding column 1 located in the light guiding installation cavity 31 , and the light guiding groove 13 is arranged opposite to the light source component 2 .

[0057] Specifically, the light guide column 1 is used to receive and guide the light from the light source component 2, and a light guide groove 13 is formed on the light guide column 1. The light guide groove 13 is recessed from a side end surface close to the light source component 2 toward a direction away from the light source component 2. The light guide groove 13 is used to allow the light from the light source component 2 to enter the light guide column 1 from the light guide groove 13, and the light guide groove 13 can also play a role in focusing light. The light guide groove 13 is set at an end surface of the light guide column 1 located in the light guide mounting cavity 31, that is, the light guide groove 13 is set toward the light source component 2, and the light guide groove 13 is set opposite to the light source component 2, so that as much light as possible can enter the light guide groove 13, which can reduce the loss of light during transmission, improve light utilization, and facilitate control of the propagation direction of light.

[0058] In some embodiments, the rubber sleeve 3 includes a first section 32 and a second section 34 connected in sequence along the light guiding direction, the light emitting end of the light source 2 extends into the first section 32, one end of the light guide column 1 extends into the second section 34, the second section 34 is connected to the first section 32 and at least part of the outer diameter is set to gradually increase in the direction away from the first section 32.

[0059] Specifically, by extending the light emitting end of the light source component 2 into the first section 32, the light source component 2 can be connected to the first section 32, thereby realizing the connection between the light source component 2 and the rubber sleeve 3; by extending one end of the light guide column 1 into the second section 34, the light guide column 1 can be connected to the second section 34, thereby realizing the connection between the light guide column 1 and the rubber sleeve 3; at the same time, by connecting the first section 32 with the second section 34, the rubber sleeve 3 can be made into a whole, thereby improving the overall structural strength of the rubber sleeve 3, and realizing the connection between the light source component 2 and the light guide column 1 through the rubber sleeve 3, so as to guide the light emitted by the light source component 2 through the light guide column 1.

[0060] And, if Figure 9-10 As shown, the outer diameter of the light guide column 1 is larger than the outer diameter of the light source component 2, so that the outer diameter of at least part of the second section 34 gradually increases in the direction away from the first section 32, so that as much light as possible can enter the light guide column 1, reducing the loss of light during propagation, improving the light utilization rate, and allowing the first section 32 and the second section 34 to be better connected to the light source component 2 and the light guide column 1 respectively, so as to avoid external glue flowing between the light guide column 1 and the light source component 2, thereby affecting the light guiding effect.

[0061] The utility model also provides a photovoltaic inverter 200.

[0062] The photovoltaic inverter 200 according to the embodiment of the utility model comprises a device housing 201 and any one of the above-mentioned light guide structures 100, and the light guide structure 100 is arranged through the peripheral wall of the device housing 201. The device housing 201 is provided in the photovoltaic inverter 200, and the device housing 201 is used to install the light guide structure 100 and protect the light guide structure 100. The light guide structure 100 is arranged through the peripheral wall of the device housing 201, and the light guide structure 100 can be installed on the device housing 201 through the cooperation between the light guide structure 100 and the peripheral wall of the device housing 201, and the device housing 201 can be used to shield and protect the light guide structure 100, so as to avoid the light source 2 being damaged and unable to emit light, or the relative position between the light guide column 1 and the light source 2 is changed due to the movement of the collision position, which affects the light guiding effect.

[0063] In some embodiments, a peripheral wall of the device housing 201 is provided with a receiving groove 2011 open outward, and a penetrating ring portion 2012 is formed on one side of the receiving groove 2011 close to the inside of the device housing 201 .

[0064] Specifically, a receiving groove 2011 is provided on the peripheral wall of the device housing 201, and the receiving groove 2011 is used to cooperate with the light-guiding structure 100. The receiving groove 2011 is constructed to be open outward, so that the light-guiding structure 100 can be easily extended into the interior of the receiving groove 2011 from the open side of the receiving groove 2011, thereby realizing the installation of the light-guiding structure 100 on the device housing 201. At the same time, a through-ring portion 2012 is formed on the side of the receiving groove 2011 close to the interior of the device housing 201, and the through-ring portion 2012 is also used to cooperate with the light-guiding structure 100, so that the connection between the light-guiding structure 100 and the device housing 201 can be realized through the receiving groove 2011 and the through-ring portion 2012 at the same time, thereby improving the connection reliability and stability between the light-guiding structure 100 and the device housing 201.
