Description

Technical Field

[0001] This application relates to the field of energy storage technology, and more particularly to an electrical component and a battery pack. Background Technology

[0002] Battery packs are devices that store electrical energy and play a crucial role in power systems, especially in areas such as renewable energy grid integration, grid frequency regulation, peak shaving and valley filling, and emergency backup. In some applications, battery packs consist of electrical components and battery cell components; the electrical components have a casing, and the battery cell components are located inside the casing.

[0003] The outer casing has an opening with a light guide at the opening, which guides the light emitted by the LEDs to the outside of the casing. There are usually several LEDs, and the light guide consists of several light guide pillars, with one light guide pillar corresponding to one LED. The light guide pillars are independent of each other, making it inconvenient to fix the light guide. Summary of the Invention

[0004] In view of the above problems, embodiments of this application provide an electrical component and a battery pack, which overcomes or at least partially solves the technical problem of inconvenient fixation of the light guide.

[0005] According to one aspect of the embodiments of this application, an electrical component is provided, including a housing, a circuit board, a plurality of LEDs, and a light guide. The housing includes a top cover with a plurality of openings. The circuit board is located inside the housing. The LEDs are disposed on the circuit board, and the circuit board provides power to the LEDs. The light guide includes a plurality of light guide pillars and a plurality of connecting bridges. Each light guide pillar includes a body portion and a protrusion extending beyond the body portion. The body portion and the connecting bridges are connected to form a ring structure, and the light guide pillars are at least partially located above the LEDs. The connecting bridges are provided with a first heat-fusion portion. A first heat-fusion member is configured to be disposed in a first heat-fusion hole. The first heat-fusion member heat-fuses and fixes the first heat-fusion portion and the top cover. The ring structure is formed by connecting the body portions of the plurality of light guide pillars and the plurality of connecting bridges, which not only improves the overall structural strength of the light guide but also facilitates the assembly of the light guide with the top cover through the openings.

[0006] In one or more of the above optional embodiments, the main body and the connecting bridge are alternately connected to form a ring structure. The light guide is provided with a connecting bridge, which is fixed to the first hot-melt component of the top cover by hot-melt through the first hot-melt hole of the first hot-melt part, which improves the convenience of fixing the light guide and enhances the connection reliability between the light guide and the top cover.

[0007] In one or more of the above optional embodiments, the plurality of light guide pillars include a first light guide pillar, and the plurality of connecting bridges include a first connecting bridge and a second connecting bridge connected to the first light guide pillar; the body portion of the first light guide pillar extends with a second hot-melt hole, the second hot-melt portion is provided with the second hot-melt hole, the top cover is provided with a second hot-melt component, the second hot-melt component is configured to be disposed in the second hot-melt hole, and the second hot-melt component heat-melts and fixes the second hot-melt portion and the top cover; the second hot-melt hole is located outside the annular structure. By providing the second hot-melt hole, when the first connecting bridge and the second connecting bridge shrink and deform, the second hot-melt component can effectively limit the body portion of the first light guide pillar through the second hot-melt hole, reducing the risk of displacement of the first light guide pillar due to the shrinkage and deformation of the first connecting bridge and the second connecting bridge.

[0008] In one or more of the above optional embodiments, the first heat-fused portion includes a first sub-heat-fused portion disposed on the first connecting bridge and a second sub-heat-fused portion disposed on the second connecting bridge; the first connecting bridge includes a first connecting portion connecting the first sub-heat-fused portion and the body portion of the first light guide post, and the second connecting bridge includes a second connecting portion connecting the second sub-heat-fused portion and the body portion of the first light guide post; the length of the first connecting portion is less than the length of the second connecting portion; the distance from the second heat-fused portion to the first connecting portion is greater than the distance from the second heat-fused portion to the second connecting portion. Through this limitation, when the first sub-heat-fused portion is heat-fused and fixed to the first heat-fused component of the top cover through the first heat-fused hole, and when the second sub-heat-fused portion is heat-fused and fixed to the first heat-fused component of the top cover through the first heat-fused hole, the heat at the first sub-heat-fused portion is transferred to the body portion of the first light guide post through the first connecting portion, and the heat at the second sub-heat-fused portion is transferred to the body portion of the first light guide post through the second connecting portion. The first connecting portion transfers more heat than the second connecting portion, and the second heat-fused hole forms a limit on the body portion of the first light guide post, reducing the risk of deformation of the first light guide post.

[0009] In one or more of the above optional embodiments, the width of the first connecting portion is less than or equal to the width of the second connecting portion.

[0010] In one or more of the above optional embodiments, the plurality of light guide pillars includes a second light guide pillar, and the body portion of the second light guide pillar is connected to a second connecting bridge.

[0011] In one or more of the above alternative embodiments, the opening extends through the top cover, and the gap between the protrusion and the top cover is less than 0.5 mm along the radial direction of the opening. This arrangement reduces the risk of external static electricity entering the housing through the gap between the protrusion and the top cover.

[0012] In one or more of the above optional embodiments, the electrical component includes a plurality of adhesive members, the number of adhesive members, the number of light guide pillars, and the number of openings being the same. A protrusion extends to an opening, and an adhesive member adheres to a body portion and a top cover, with the adhesive member surrounding the outer side of the protrusion. The adhesive member adheres to the body portion of the light guide and the housing, forming a sealed interface between the light guide and the housing. This reduces the risk of external static electricity entering the housing through the opening, and reduces the risk of electrical components inside the housing, such as circuit boards, being damaged or even malfunctioning due to electrostatic interference.

[0013] The connecting bridge of the light guide is fixed to the first hot-melt component of the top cover, which enhances the connection reliability between the light guide and the top cover. The light guide and the top cover jointly compress the adhesive, which can effectively activate the adhesive performance of the adhesive and enable the adhesive to fully fit the body and the top cover under pressure, further improving the sealing effect and further reducing the risk of external static electricity entering the shell through the opening.

[0014] In one or more of the above optional embodiments, the main body of the light guide column is located inside the housing, the protrusion of the light guide column extends to the opening, the adhesive is located inside the housing, and the adhesive is bonded between the main body of the light guide column and the top cover. By setting the main body of the light guide column and the adhesive inside the housing, the housing protects the main body of the light guide column and the adhesive.

[0015] In one or more of the above optional embodiments, a second hot melt hole is provided. When the first connecting bridge and the second connecting bridge shrink and deform, the second hot melt component can effectively limit the body of the first light guide post through the second hot melt hole, thereby enhancing the reliability of the adhesive bonding the body of the first light guide post to the top cover and reducing the risk of external static electricity entering the shell.

[0016] In one or more of the above optional embodiments, the adhesive is double-sided tape. Reliable bonding between the body of the light guide post and the top cover is achieved using double-sided tape.

[0017] In one or more of the above optional embodiments, the electrical component includes a light shield connected to the circuit board. The light shield has a cylindrical structure and a through hole, with the body of the light shield closing the through hole, and the LED chip located in the through hole. By setting up the light shield, the risk of light leakage emitted by the LED chip is reduced, and the luminous efficiency of the LED chip is improved; by setting up the light shield, stray light interference is reduced, and the purity of the light emitted by the LED chip is improved.

[0018] The number of light shields is the same as the number of light guide pillars, and the body of one light guide pillar closes one end of the through hole of one light shield.

[0019] In one or more of the above optional embodiments, the light guide post includes a protrusion extending into the through hole. This protrusion engages with the inner wall of the light shield at the through hole, reducing the risk of light emitted by the LED chip leaking from one end of the through hole.

[0020] In one or more of the above optional embodiments, the housing includes a lower housing, a top cover is disposed on the lower housing, and the top cover and lower housing together form a receiving space, in which the LED, circuit board, and light guide are located. The top cover, circuit board, and lower housing are all provided with mounting holes, and the electrical components include fasteners, which secure the top cover, circuit board, and lower housing through the mounting holes. This arrangement achieves a stable connection between the top cover, circuit board, and lower housing.

[0021] According to one aspect of the embodiments of this application, a battery pack is provided, including a cell assembly and the aforementioned electrical components. The cell assembly is located in a housing and connected to a circuit board. This configuration enables the charging and discharging functions of the battery pack.

[0022] In one or more of the above optional embodiments, the LED beads are configured to indicate the battery cell assembly's charge level. This setting enables the display of the battery cell assembly's charge level, allowing users to easily identify the remaining charge through the LED beads and improving the convenience of using the battery pack.

The light guide pillar 41 is at least partially located above the lamp bead 30, so that the light guide pillar 41 guides the light emitted by the lamp bead 30 from the opening 11s to the outside of the housing 10.

[0040] The connecting bridge 42 is provided with a first heat-fusion part 420, the first heat-fusion part 420 is provided with a first heat-fusion hole 420s, and the top cover 11 is provided with at least one first heat-fusion element 111. The first heat-fusion element 111 is configured to be provided in the first heat-fusion hole 420s, and the first heat-fusion element 111 heat-fuses and fixes the first heat-fusion part 420 and the top cover 11.

[0041] Figure 2 and Figure 5 The first heat-melting component 111 is in the pre-heat-melting state. Figure 6 The first hot-melt component 111 is in the state after hot melting.

[0042] The main body 4101 of several light guide pillars 41 is connected to several connecting bridges 42 to form a ring structure, which not only improves the overall structural strength of the light guide 40, but also facilitates the assembly of the light guide 40 with the top cover 11 through the opening 11s.

[0043] In one implementation of this application embodiment, the main body 4101 and the connecting bridge 42 are alternately connected to form a ring structure. The light guide 40 is provided with the connecting bridge 42, and the connecting bridge 42 is fixed to the first hot-melt component 111 of the top cover 11 by hot-melt fixing through the first hot-melt hole 420s of the first hot-melt part 420, which improves the convenience of fixing the light guide 40 and enhances the connection reliability between the light guide 40 and the top cover 11.

[0044] like Figure 2 As shown, in one implementation of this application embodiment, the number of LED beads 30 is the same as the number of light guide pillars 41, and a light guide pillar 41 is at least partially located above an LED bead 30, with an LED bead 30 correspondingly disposed between a light guide pillar 41 and the circuit board 20.

[0045] In one implementation of the embodiments of this application, such as Figure 5 As shown, and in combination Figure 2 The main body 4101 of the light guide post 41 is located inside the housing 10, and the protrusion 4102 of the light guide post 41 extends to the opening 11s. By placing the main body 4101 of the light guide post 41 inside the housing 10, the housing 10 protects the main body 4101 of the light guide post 41.

[0046] like Figure 3 or Figure 4 As shown, in one implementation of this application embodiment, the light guide post 41 and the connecting bridge 42 are integrally formed structures, which enhances the stability of the overall structure of the light guide 40.

[0047] like Figure 3 or Figure 4 As shown, in one implementation of this application embodiment, a connecting bridge 42 is provided with a first heat-fusion portion 420, and the first heat-fusion portion 420 is provided with a first heat-fusion hole 420s. Alternatively, in one implementation of this application embodiment, a connecting bridge 42 is provided with two first heat-fusion portions 420 spaced apart, and each first heat-fusion portion 420 is provided with a first heat-fusion hole 420s. Correspondingly, please refer to... Figure 5The number of first hot-melt components 111 is the same as the number of first hot-melt holes 420s, to enhance the connection strength between the light guide component 40 and the top cover 11 via the connecting bridge 42, the first hot-melt components 111, and the top cover 11. For example, there are four connecting bridges 42, each with two first hot-melt holes 420s, for a total of eight first hot-melt holes 420s. The top cover 11 is correspondingly provided with eight first hot-melt components 111, and the eight first hot-melt holes 420s are respectively hot-melted and fixed to the eight first hot-melt components 111.

[0048] In one implementation of the embodiments of this application, please refer to Figure 3 or Figure 4 The system includes several light guide pillars 41, including a first light guide pillar 411, and several connecting bridges 42, including a first connecting bridge 421 and a second connecting bridge 422 connected to the first light guide pillar 411. A second heat-fusion portion 401 extends from the body portion 4101 of the first light guide pillar 411. The second heat-fusion portion 401 is provided with a second heat-fusion hole 401s, which, when combined... Figure 5 and Figure 6 The top cover 11 is provided with a second hot melt component 112 and a second hot melt hole 401s located outside the annular structure.

[0049] Figure 5 The second heat-melting component 112 is in the pre-heat-melting state. Figure 6 The second heat-fused component 112 is in a heat-fused state. The second heat-fused component 112 is configured to be located in the second heat-fused hole 401s, and the second heat-fused component 112 heat-fused and fixes the second heat-fused part 401 and the top cover 11. By setting the second heat-fused hole 401s, when the first connecting bridge 421 and the second connecting bridge 422 shrink and deform, the second heat-fused component 112 can limit the body part 4101 of the first light guide post 411 through the second heat-fused hole 401s, reducing the risk of displacement of the first light guide post 411 due to the shrinkage and deformation of the first connecting bridge 421 and the second connecting bridge 422.

[0050] In one implementation of this application, the second hot melt hole 401s is at least partially located in the extension direction of the first connecting bridge 421. When the first connecting bridge 421 shrinks and deforms, it is beneficial for the second hot melt component 112 to limit the body portion 4101 of the first light guide post 411 through the second hot melt hole 401s.

[0051] In one implementation of the embodiments of this application, such as Figure 4As shown, the first heat-sealing section 420 includes a first sub-heat-sealing section 4201 disposed on the first connecting bridge 421 and a second sub-heat-sealing section 4202 disposed on the second connecting bridge 422.

The length d1 of the first connecting portion 43 is less than the length d2 of the second connecting portion 44. The distance d3 from the second heat-sealing section 4201 to the first connecting portion 43 is greater than the distance d4 from the second heat-sealing section 4201 to the second connecting portion 44. The length d1 of the first connecting portion 43 is the length of the first connecting portion 43 along the extension direction of the first connecting bridge 421, and the length d2 of the second connecting portion 44 is the length of the second connecting portion 44 along the extension direction of the second connecting bridge 422.

[0052] Please combine Figure 2 Multiple first heat-fused parts 11 are included. When the first sub-heat-fused part 4201 is heat-fused and fixed to the first heat-fused part 11 through the first heat-fused hole 420s, and when the second sub-heat-fused part 4202 is heat-fused and fixed to the first heat-fused part 11 through the first heat-fused hole 420s, the heat at the first sub-heat-fused part 4201 is transferred to the body part 4101 of the first light guide post 411 through the first connecting part 43. The heat at the second sub-heat-fused part 4202 is transferred to the body part 4101 of the first light guide post 411 through the second connecting part 44. The first connecting part 43 transfers more heat than the second connecting part 44, and forms a limit on the body part 4101 of the first light guide post 411 through the second heat-fused hole 401s, reducing the risk of deformation of the first light guide post 411.

[0053] The first sub-thermal fusion section 4201 is provided with a first thermal fusion hole 420s that is thermally fixed to the first thermal fusion component 111, and the second sub-thermal fusion section 4202 is provided with a first thermal fusion hole 420s that is thermally fixed to the first thermal fusion component 111 of the top cover 11.

[0058] The first light guide post 411, the second light guide post 412, the third light guide post 413 and the fourth light guide post 414 are respectively arranged in the ring structure formed by the light guide 40, which helps to disperse stress and reduce the risk of overall structural instability of the light guide 40 due to local deformation of the light guide 40.

[0059] When the light guide pillars 41 include a first light guide pillar 411, a second light guide pillar 412, a third light guide pillar 413, and a fourth light guide pillar 414, the lamp beads 30 include a first lamp bead 31, a second lamp bead 32, a third lamp bead 33, and a fourth lamp bead 34. The first lamp bead 31 is correspondingly arranged with the first light guide pillar 411, the second lamp bead 32 is correspondingly arranged with the second light guide pillar 412, the third lamp bead 33 is correspondingly arranged with the third light guide pillar 413, and the fourth lamp bead 34 is correspondingly arranged with the fourth light guide pillar 414. Through this one-to-one correspondence, the light emitted by each lamp bead 30 is independently guided by its corresponding light guide pillar 41, reducing optical path interference.

[0060] In one implementation of the embodiments of this application, please refer to Figure 3 or Figure 4 A third connecting portion 45 is provided between the fourth light guide post 414 and the first connecting bridge 421, and a fourth connecting portion 46 is provided between the fourth light guide post 414 and the fourth connecting bridge 424. The fourth light guide 414 has the same structure and function as the first light guide 411, the third connecting portion 45 has the same structure and function as the first connecting portion 43, and the fourth connecting portion 46 has the same structure and function as the second connecting portion 44, which will not be described in detail here.

[0061] The fourth light guide post 414 has a third heat-fusion section 402 extending from its main body 4101. The third heat-fusion section 402 has a third heat-fusion hole 402s and is located outside the annular structure. The third heat-fusion section 402 has the same structure and function as the second heat-fusion section 401, and the third heat-fusion hole 402s has the same structure and function as the second heat-fusion hole 401s, which will not be described in detail here.

[0062] In one implementation of the embodiments of this application, such as Figure 3 or Figure 4 As shown, and in combination Figure 2 The second light guide post 412 has a fifth connecting part 47 between its main body 4101 and the third connecting bridge 423. The third light guide post 413 has a sixth connecting part 48 between its main body 4101 and the third connecting bridge 423. The sixth connecting part 48 has the same structure and function as the fifth connecting part 47, and will not be described in detail here.

[0063] In one implementation of the embodiments of this application, please refer to Figure 7 The opening 11s penetrates the top cover 11, and extends radially along the opening 11s by D1 ( Figure 7 (One direction of the radial direction D1 of the opening 11s is shown). The gap g between the protrusion 4102 and the top cover 11 is less than 0.5 mm. This arrangement reduces the risk of external static electricity entering the housing 10 through the gap g between the protrusion 4102 and the top cover 11.

[0064] In one implementation of this application, the gap g between the protrusion 4102 and the top cover 11 is filled with sealant to reduce the risk of external static electricity entering the housing 10 along the gap.

[0065] In one implementation of this application, the opening 11s is closed and does not penetrate the top cover 11.

[0066] In one implementation of the embodiments of this application, please refer to the following: Figure 2 , Figure 3 and Figure 5 The electrical component 100 includes adhesive members 50, the number of which is the same as the number of light guide pillars 41 and the number of openings 11s.
