Description

Technical Field

[0001] The utility model relates to the technical field of light guide devices, and in particular to a special-shaped light guide, a charging component, and a prosthesis. Background Art

[0002] Many electronic products have a charging function. In order to indicate the current charging status, an LED light is usually set inside the device that needs to be charged, and then the light of the LED light is guided outward through a light guide. The user can see the light status of the LED light through the light emitting surface of the light guide. For example, if the light emitting surface of the light guide is green, it means that it is fully charged. If the light emitting surface of the light guide is red, it means that it is not fully charged.

[0003] Generally, light guides are regular cylindrical or rectangular structures. Taking the cylinder as an example, the bottom surface of one end of the cylinder is the light-input surface, and the bottom surface of the other end is the light-output surface. The light emitted by the LED lamp enters the light guide through the light-input surface, is transmitted along the axis of the cylinder to the light-output surface, and then emits outward. In this process, the light transmission path is a straight line, so the light attenuation is less, and a strong light can still be seen at the light-output surface.

[0004] In some special products, such as prostheses, due to the structural design of the products themselves, the normals of the light-input surface and the light-output surface do not coincide. In this case, traditional light guides with regular structures cannot be used. For example, special-shaped light guides, charging components, and prostheses with Z-shaped structures are required. The problem with using special-shaped light guides, charging components, and prostheses is that the light is no longer transmitted in a straight line, the brightness at the light-output surface is low, and the key charging indication effect is poor.

[0005] Therefore, it is necessary to improve the existing light guide to solve the problem of low brightness of the light emitting surface when the normal lines of the light incident surface and the light emitting surface do not coincide.

[0006] The above information disclosed in this Background section is included only for enhancement of understanding of the background of the present disclosure and therefore it may contain information that does not form the prior art that is currently known to a person of ordinary skill in the art. Utility Model Content

[0007] One purpose of the utility model is to provide a special-shaped light guide, a charging assembly, and a prosthesis, which can effectively solve the problem of low brightness of the light-emitting surface when the normals of the light-incoming surface and the light-emitting surface do not overlap.

[0008] To achieve the above objectives, on the one hand, the utility model provides a special-shaped light guide, comprising:

[0012] Optionally, the silver coating is an electroplated coating.

[0015] Optional,

[0016] The bottom of the process groove is recessed toward the first light guide portion, so that the wall thickness of the connecting position between the first light guide portion and the second light guide portion tends to be consistent with the wall thickness of the first light guide portion.

[0017] Optionally, the cross-sectional shape of the first light guide portion on the first cross-section is a trapezoidal structure, wherein the first cross-section is parallel to the normal line of the first light input and output surface;

[0018] The second light guiding portion is located on the longer bottom side of the trapezoidal structure.

[0019] Optionally, the groove wall and / or the groove bottom of the process groove is a light-incoming surface, and the first light-incoming and light-exiting surface and / or the second light-incoming and light-exiting surface is a light-exiting surface.

[0021] Wherein, the LED lamp is arranged opposite to any light inlet and outlet surface of the special-shaped light guide member.

[0022] On the other hand, a prosthesis is provided, comprising the charging assembly.

[0023] The beneficial effects of the utility model are: providing a special-shaped light guide, a charging component, and a prosthesis, wherein a silver coating is applied to the circumferential outer side surface where no light is required to enter or exit, and the silver coating has the advantages of high reflectivity and low absorption of light, so it can effectively suppress the light from being emitted outward through the circumferential outer surface, and maximize the light emission from the second light input and output surface, thereby improving the brightness of the second light input and output surface.

[0034] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the embodiment described below is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] In the description of the present utility model, it is to be understood that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centrally arranged component at the same time.

[0036] In addition, terms such as "long", "short", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention. They do not indicate or imply that the device or component referred to must have this specific direction or operate with a specific direction structure, and should not be understood as a limitation of the present invention.

[0037] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0038] The utility model provides a special-shaped light guide, a charging assembly, and a prosthesis, which are suitable for application scenarios where the charging status is indicated during the charging process, and can effectively solve the problem of low brightness of the light-emitting surface when the normals of the light-inlet surface and the light-emitting surface do not coincide.

[0039] The prosthesis provided in this embodiment includes a prosthesis body with a battery and a charging component for charging the battery in the prosthesis body.

[0040] The charging component includes a charging interface, a control mainboard electrically connected to the charging interface, an LED lamp electrically connected to the control mainboard, and a special-shaped light guide arranged opposite to the LED lamp.

[0041] See also Figure 1 and Figure 2 The special-shaped light guide comprises a first light guide portion 1 and a second light guide portion 2. The end face of one end of the first light guide portion 1 is a first light inlet and outlet surface 101; one end of the second light guide portion 2 is connected to the other end of the first light guide portion 1, and the end face of the other end is a second light inlet and outlet surface 201; wherein the normal lines of the first light inlet and outlet surface 101 and the second light inlet and outlet surface 201 do not overlap, and the circumferential outer side surfaces 3 of the first light guide portion 1 and the second light guide portion 2 are coated with a silver coating.

[0042] The special-shaped light-guiding member, charging assembly, and prosthesis provided in this embodiment are coated with a silver coating on the circumferential outer side surface 3 where no light is required to enter or exit. The silver coating has the advantages of high reflectivity and low absorption of light, so it can effectively suppress the light from being emitted outward through the circumferential outer side surface 3, thereby maximizing the amount of light emitted outward from the second light inlet and outlet surface 201, thereby increasing the brightness of the second light inlet and outlet surface 201.

[0043] Therefore, the special-shaped light guide, charging assembly, and prosthesis provided in this embodiment can effectively solve the problem of low brightness of the second light input and output surface 201 when the normals of the first light input and output surface 101 and the second light input and output surface 201 do not overlap.

[0044] In this embodiment, the LED light is arranged opposite to any light-inlet and light-outlet surface of the special-shaped light guide. For example, when the first light-inlet and light-outlet surface 101 is inside the prosthesis and the second light-inlet and light-outlet surface 201 is outside the prosthesis, at this time, the first light-inlet and light-outlet surface 101 is the light-inlet surface and the second light-inlet and light-outlet surface 201 is the light-outlet surface, and the LED light is arranged opposite to the first light-inlet and light-outlet surface 101, so that the user can judge the current charging status through the second light-inlet and light-outlet surface 201 from the outside. Furthermore, if the control mainboard detects that it is not fully charged, the LED light is controlled to emit red light. At this time, the user sees the red light on the second light-inlet and light-outlet surface 201, and knows that it is not fully charged; if the control mainboard detects that it is fully charged, the LED light is controlled to emit green light. At this time, the user sees the green light on the second light-inlet and light-outlet surface 201, and knows that it is fully charged.

[0045] Alternatively, when the second light inlet and outlet surface 201 is inside the prosthesis and the first light inlet and outlet surface 101 is outside the prosthesis, the second light inlet and outlet surface 201 is the light inlet surface and the first light inlet and outlet surface 101 is the light outlet surface, and the LED light is arranged opposite to the second light inlet and outlet surface 201, so that the user can judge the current charging status from the outside through the first light inlet and outlet surface 101. Both the first light inlet and outlet surface 101 and the second light inlet and outlet surface 201 can be used as the light inlet surface or the light outlet surface, and the present invention does not limit this.

[0046] Optionally, the silver coating is an electroplating coating, which has higher coating uniformity.

[0047] In this embodiment, the first light guide part 1 is a plate-like structure, and the second light guide part 2 is a block-like structure. The second light guide part 2 is provided with a process groove 202 extending from the second light inlet and outlet surface 201 toward the first light guide part 1, so that the circumferential wall thickness of the second light guide part 2 tends to be consistent with the wall thickness of the first light guide part 1. Consistent wall thickness can not only improve the uniformity of light guiding, but also reduce injection molding defects and improve the product yield of special-shaped light guide parts.

[0048] Furthermore, the cross-sectional shape of the first light guide portion 1 on the first section is a trapezoidal structure, wherein the first section is parallel to the normal line of the first light input and output surface 101; and the second light guide portion 2 is located on the longer bottom side of the trapezoidal structure.

[0049] The wall thickness of the connection position 4 between the first light guide part 1 and the second light guide part 2 is theoretically the largest. Figure 3 The bottom 2021 of the process groove 202 is recessed toward the first light guide part 1, which is beneficial to thinning the wall thickness of the connection position 4 between the first light guide part 1 and the second light guide part 2, so that the wall thickness of the connection position 4 between the first light guide part 1 and the second light guide part 2 tends to be consistent with the wall thickness of the first light guide part 1, further reducing poor injection molding and uneven light guiding.

[0050] In this embodiment, the groove wall and / or groove bottom 2021 of the process groove 202 is the light-incoming surface, and the first light-in-outgoing surface 101 and / or the second light-in-outgoing surface 201 is the light-emitting surface. For example, an LED lamp can be placed in the process groove 202, and the groove wall and / or groove bottom 2021 of the process groove 202 is used as the light-incoming surface. In this case, the first light-in-outgoing surface 101 and the second light-in-outgoing surface 201 are both used as the light-emitting surface; or, one LED lamp can be placed in the process groove 202, and another LED lamp can be placed at the first light-in-outgoing surface 101. In this case, only the second light-in-outgoing surface 201 is used as the light-emitting surface, and the light emitted by the two LED lamps can be transmitted to the second light-in-outgoing surface 201, which greatly improves the light-emitting brightness at the second light-in-outgoing surface 201.

[0051] Of course, if there is no need to place an LED lamp in the process tank 202 , a silver coating may also be applied to the tank wall and / or the tank bottom 2021 , and the present invention is not limited to this.

[0052] To sum up, the special-shaped light guide, charging assembly, and prosthesis provided in this embodiment have the following beneficial effects: a silver coating is applied to the circumferential outer side surface 3 where no light is required to enter or exit. The silver coating has the advantages of high reflectivity and low absorption of light, so it can effectively suppress the light from being emitted outward through the circumferential outer side surface 3, thereby maximizing the amount of light emitted outward from the second light inlet and outlet surface 201, thereby improving the brightness of the second light inlet and outlet surface 201.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
