Description

Technical Field

[0001] This disclosure relates to the technical field of power batteries, and in particular to a battery light emission protection structure and battery pack. Background Technology

[0002] Currently, battery packs typically include indicator lights to display battery level or fault signals. However, battery packs like the one disclosed in Chinese patent document CN220753597U, due to their structural design, allow water or dust from the surrounding environment to directly affect the display device. Water can easily seep into the display device, causing short circuits or burnout of the indicator light circuits, while dust accumulation on the display device reduces the light output of the indicator lights. Utility Model Content

[0003] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a battery light emission protection structure and battery pack that can simultaneously provide waterproof and dustproof protection.

[0004] The purpose of this disclosure is achieved through the following technical solution:

[0005] A battery protection light-emitting structure, comprising:

[0006] A housing, wherein an installation port is provided on the housing;

[0007] The display light assembly is installed inside the housing;

[0008] The battery protection light-emitting structure also includes a light guide component and a light-shielding cover;

[0009] The light guide component is installed at the mounting port, with its light-incident end facing the light-emitting part of the display lamp assembly, and its light-emitting end located on the outside of the housing. The light-shielding cover is installed on the outside of the housing and positioned above the light-emitting end of the light guide component to block external water or dust. A portion of the light-shielding cover is located on the side of the light-emitting end of the light guide component away from the housing and extends below the light-emitting end of the light guide component to form a protective rim. The protective rim and the housing together form a light-emitting window. The light-emitting window faces the same direction as gravity and is used to allow the light-emitting end of the light guide component to emit light to the outside.

[0010] In some embodiments, the light-shielding shield includes an upper shield and a side shield assembly connected together. The upper shield is located above the light-emitting end of the light guide assembly. The side shield assembly is arranged laterally around the outer periphery of the light-emitting end of the light guide assembly. The lower edge of the side shield assembly extends to the bottom of the light-emitting end of the light guide assembly and forms the protective edging.

[0011] In some embodiments, the side shielding plate group includes a first side plate, a middle side plate, and a second side plate connected in sequence; the middle side plate is located on the side of the light-emitting end of the light guide assembly away from the housing and is connected to the upper shielding plate; the first side plate and the second side plate are respectively located at both ends of the light guide assembly and are respectively connected to the upper shielding plate; the lower edge of the first side plate, the lower edge of the middle side plate, and the lower edge of the second side plate extend to below the light-emitting end of the light guide assembly and together form the protective edging.

[0012] In some embodiments, the middle side panel is tilted relative to the upper shielding panel.

[0013] In some embodiments, the light guide assembly includes a light-emitting block and a light-incident post. The light-emitting block is embedded in the mounting port, and the light-emitting surface of the light-emitting block faces the light-emitting window. The light-incident post is disposed on the light-emitting block, and the end of the light-incident post forms a light-collecting incident groove. The lamp beads of the display lamp group are disposed facing the light-collecting incident groove.

[0014] In some embodiments, the number of light-incident guide pillars is at least two, and the at least two light-incident guide pillars are arranged side by side along the length direction of the light-outcident block; the end of each light-incident guide pillar forms a light-collecting incident slot, and each lamp bead of the display lamp group is respectively oriented toward one of the light-collecting incident slots.

[0015] In some embodiments, the light guide assembly further includes a light guide rib, which is fixed on the light output guide block and located between two adjacent light input guide posts; both adjacent light input guide posts are connected to the light guide rib.

[0016] In some embodiments, the inner wall of the light-collecting incident slot is a hemispherical surface.

[0017] In some embodiments, a reflective slope is formed on the side of the light-emitting block opposite to the light-emitting surface, and the reflective slope is opposite to the position of the light-collecting incident groove.

[0018] A battery pack comprising the battery protection light-emitting structure of any of the above embodiments.

[0019] Compared with the prior art, this disclosure has at least the following advantages:

[0020] The aforementioned battery protection light-emitting structure, with its light-shielding shield positioned above the light-emitting end of the light guide component, effectively protects the light-emitting end from direct contact with water, preventing short circuits or burnout of the indicator light assembly. Furthermore, because the light-shielding shield extends from the light-emitting end of the light guide component to the side furthest from the housing, and below the light-emitting end, the protective edge and housing together form a light-emitting window below the light-emitting end. Since the light-emitting window faces the same direction as gravity, dust must overcome gravity to adhere to the light guide component, thus reducing dust accumulation at its light-emitting end.

[0032] To facilitate understanding of this disclosure, a more complete description will be given below with reference to the accompanying drawings, which illustrate preferred embodiments of the present disclosure. However, this disclosure can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure.

[0033] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0036] Please refer to the following: Figure 1 and Figure 2One embodiment of the battery protection light-emitting structure includes a housing 100, an indicator lamp assembly 200, a light guide assembly 300, and a light shield 400. The housing 100 has a mounting opening 101. The indicator lamp assembly 200 is mounted inside the housing 100. The light guide assembly 300 is mounted at the mounting opening 101, with its light-incident end facing the light-emitting portion 210 of the indicator lamp assembly 200, and its light-emitting end located outside the housing 100. The light shield 400 is mounted on the housing. The outer side of the housing 100 is blocked above the light-emitting end of the light guide assembly 300 to prevent water or dust from the outside. The part of the light shield 400 is located on the side of the light-emitting end of the light guide assembly 300 away from the housing 100, and extends to the bottom of the light-emitting end of the light guide assembly 300 to form a protective edging 4110. The protective edging 4110 and the housing 100 form a light-emitting window 401. The light-emitting window 401 is oriented in the same direction as the direction of gravity and is used to allow the light-emitting end of the light guide assembly 300 to emit light to the outside.

[0037] It is understandable that, since the light shield 400 is positioned above the light-emitting end of the light guide assembly 300, it can protect the light-emitting end of the light guide assembly 300, preventing external water from directly impacting the light guide assembly 300 and the display lamp assembly 200, thus avoiding short circuits or burnout of the display lamp assembly 200 circuit. Simultaneously, since part of the light shield 400 is located on the side of the light guide assembly 300 away from the housing 100 and extends below the light-emitting end of the light guide assembly 300, the protective edge 4110 and the housing 100 can form a light-emitting window 401 below the light-emitting end of the light guide assembly 300. Because the orientation of the light-emitting window 401 is the same as the direction of gravity, dust needs to overcome gravity to adhere to the light guide assembly 300, thereby reducing dust accumulation on the light-emitting end of the light guide assembly 300.

[0038] Please see Figure 2 In some embodiments, the light-shielding shield 400 includes an upper shielding plate 410 and a side shielding plate group 420 connected to each other. The upper shielding plate 410 is located above the light-emitting end of the light guide assembly 300; the side shielding plate group 420 is arranged laterally around the outer periphery of the light-emitting end of the light guide assembly 300; the lower edge of the side shielding plate group 420 extends to the lower part of the light-emitting end of the light guide assembly 300 and forms a protective rim 4110. It can be understood that since the upper shielding plate 410 is located above the light-emitting end of the light guide assembly 300 and the side shielding plate group 420 is arranged laterally around the outer periphery of the light-emitting end of the light guide assembly 300, the light-shielding shield 400 can not only shield the upper and side parts of the light guide assembly 300 to ensure that light is emitted from the light-emitting window 401, but also improve the protection of the light guide assembly 300, thereby reducing the occurrence of water or dust splashing from the outside to the light-emitting end of the light guide assembly 300.

[0039] Please refer to the following: Figure 2 and Figure 3 In some embodiments, the side shielding plate group 420 includes a first side plate 4210, a middle side plate 4220 and a second side plate 4230 connected in sequence; the middle side plate 4220 is located on the side of the light guide assembly 300 away from the housing 100 at the light-emitting end and is connected to the upper shielding plate 410; the first side plate 4210 and the second side plate 4230 are respectively located at both ends of the light guide assembly 300 and are respectively connected to the upper shielding plate 410; the lower edge of the first side plate 4210, the lower edge of the middle side plate 4220 and the lower edge of the second side plate 4230 extend to the lower part of the light guide assembly 300 at the light-emitting end and together form a protective edging 4110. It is understandable that since the middle side plate 4220 is located on the side of the light-emitting end of the light guide assembly 300 away from the housing 100 and is connected to the upper shielding plate 410, and the first side plate 4210 and the second side plate 4230 are located at both ends of the light guide assembly 300 and are connected to the upper shielding plate 410 respectively, a tight connection structure can be formed between the side shielding plate group 420 and the upper shielding plate 410 to provide higher protection for the light guide assembly 300.

[0040] Please see Figure 2 In some embodiments, the middle side panel 4220 is inclined relative to the upper shielding panel 410. It is understood that because the middle side panel 4220 is inclined relative to the upper shielding panel 410, water or dust on the upper shielding panel 410 can move downwards along the middle side panel 4220 and detach from the battery protection light-emitting structure, thereby reducing water or dust accumulation. In some embodiments, the display lamp assembly 200 is fixedly connected to the housing 100 by locking screws 230.

[0041] Please see Figure 2 In some embodiments, the light guide assembly 300 includes a light-emitting block 310 and a light-incident post 320. The light-emitting block 310 is embedded in the mounting port 101, and the light-emitting surface 3110 of the light-emitting block 310 faces the light-emitting window 401. The light-incident post 320 is disposed on the light-emitting block 310, and the end of the light-incident post 320 forms a light-collecting incident groove 3210. The lamp beads 220 of the display lamp group 200 are disposed facing the light-collecting incident groove 3210. It is understandable that, since the light-incident post 320 is disposed on the light-outcident block 310, and the light-outceasing surface 3110 of the light-outceasing block 310 faces the light-outceasing window 401, and the lamp beads 220 of the display lamp group 200 are disposed facing the light-collecting incident groove 3210 formed at the end of the light-incident post 320, the light from the lamp beads 220 of the display lamp group 200 can be collected through the light-collecting incident groove 3210 and guided to the light-outceasing block 310 through the light-incident post 320, so that the light is finally projected onto the light-outceasing window 401 through the light-outceasing surface 3110 of the light-outceasing block 310.

[0042] Please refer to the following: Figure 4 and Figure 5 In some embodiments, at least two light-incident guide pillars 320 are arranged side-by-side along the length of the light-outcident block 310. Each light-incident guide pillar 320 has a light-collecting incident groove 3210 at its end, and each LED 220 of the display lamp group 200 faces one of these light-collecting incident grooves 3210. It can be understood that because at least two light-incident guide pillars 320 are arranged side-by-side along the length of the light-outcident block 310, and each LED 220 of the display lamp group 200 faces the light-collecting incident groove 3210 of a light-incident guide pillar 320, the light from each LED 220 can be guided to the light-outcident block 310 through the light-incident guide pillars 320, and the power level can be displayed in the light-emitting window 401 through the light-emitting surface 3110 of the light-outcident block 310. In this embodiment, the light from the light-incident guide pillars 320 forms a light band on the light-outcident block 310, and the length of the light band indicates the power level.

[0043] Please see Figure 4 In some embodiments, the light guide assembly 300 further includes a light guide rib 330, which is fixed to the light emitting guide block 310 and located between two adjacent light-incident guide posts 320; both adjacent light-incident guide posts 320 are connected to the light guide rib 330. It can be understood that since both adjacent light-incident guide posts 320 are connected to the light guide rib 330 fixed to the light emitting guide block 310, not only can the light-incident guide posts 320 be connected into a continuous light strip to improve the display effect, but the connection strength between the light guide assemblies 300 can also be enhanced to improve durability. In this embodiment, the light emitting guide block 310, the light-incident guide posts 320, and the light guide rib 330 are integrally formed.

[0044] Please refer to the following: Figure 2 and Figure 5 In some embodiments, the inner wall of the light-collecting incident groove 3210 is a hemispherical surface. It can be understood that because the inner wall of the light-collecting incident groove 3210 is a hemispherical surface, more light from the LED beads 220 of the display lamp group 200 can be collected, increasing the brightness of the light-emitting surface 3110 of the light guide block 310, thereby improving the display effect.

[0045] Please see Figure 2In some embodiments, a reflective slope 3120 is formed on the side of the light-emitting block 310 opposite to the light-emitting surface 3110, and the reflective slope 3120 is positioned opposite to the light-collecting incident groove 3210. It can be understood that because the reflective slope 3120 is positioned opposite to the light-collecting incident groove 3210 and is positioned opposite to the light-emitting surface 3110, the light from the LED beads 220 of the display lamp group 200 entering from the light-collecting incident groove 3210 can be reflected by the reflective slope 3120 back to the light-emitting surface 3110, thereby further enhancing the brightness of the light-emitting surface 3110. In this embodiment, the reflective slope 3120 is formed by coating the slope of the light-emitting block 310 with a white glossy coating and curing it. Of course, this is not limited to this, and those skilled in the art can make other choices as needed.

[0046] Please combine Figure 1 and Figure 2 As shown, a battery pack includes the battery protection light-emitting structure of any of the above embodiments. It can be understood that by applying the battery protection light-emitting structure of this disclosure to a battery pack, since the light shield 400 is positioned above the light-emitting end of the light guide assembly 300, the light-emitting end of the light guide assembly 300 can be protected by the light shield 400, thus preventing external water from directly affecting the light guide assembly 300 and the display lamp group 200, causing a short circuit or burnout in the display lamp group 200 circuit. Meanwhile, since part of the light shield 400 is located on the side of the light-emitting end of the light guide component 300 away from the housing 100 and extends to the bottom of the light-emitting end of the light guide component 300, the protective edge 4110 can form a light-emitting window 401 with the housing 100 below the light-emitting end of the light guide component 300. Since the orientation of the light-emitting window 401 is the same as the direction of gravity, dust needs to overcome gravity to adhere to the light guide component 300, thereby reducing the accumulation of dust on the light-emitting end of the light guide component 300.

[0047] Compared with the prior art, this disclosure has at least the following advantages:

[0048] The aforementioned battery protection light-emitting structure, with the light-shielding shield 400 positioned above the light-emitting end of the light guide component 300, effectively protects the light-emitting end of the light guide component 300 from direct contact with external water, preventing short circuits or burnout of the display lamp assembly 200. Simultaneously, because a portion of the light-shielding shield 400 is located on the side of the light guide component 300 away from the housing 100 and extends below the light-emitting end, the protective edge 4110 and the housing 100 together form a light-emitting window 401 below the light-emitting end of the light guide component 300. Since the orientation of the light-emitting window 401 is the same as the direction of gravity, dust must overcome gravity to adhere to the light guide component 300, thus reducing dust accumulation on the light-emitting end of the light guide component 300.

[0049] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
