Description

Technical Field

[0001] This application relates to the field of electrical connector technology, and more specifically to an electrical end structure assembly. Background Technology

[0002] With the development of battery racks, batteries, as a widely used power source, provide power to various devices in daily life and work. The main function of traditional battery racks is to house and secure batteries, ensuring a stable electrical connection between the batteries and the device for normal operation. For example, in devices like headlamps, the battery rack is responsible for holding the batteries and powering the headlamp.

[0003] However, existing battery racks have many limitations that urgently need to be addressed. On the one hand, their single function is a prominent issue, only meeting the battery's carrying and basic power supply needs. When the battery has remaining power but is insufficient to support the normal operation of the device, the battery rack becomes useless and cannot provide further convenience to the user. For example, when the battery power drops and cannot stably power a high-power headlamp, the headlamp goes out, and at this time, the traditional battery rack has no other use, resulting in a waste of resources.

[0004] On the other hand, when a user is in a dark environment and the headlamp suddenly stops working due to insufficient battery power, and there are no other lighting devices around, the user will be in great inconvenience and will find it difficult to complete tasks such as viewing objects or performing operations.

[0005] Therefore, how to solve the problem of the single function of traditional battery racks and how to continue to provide lighting function when the battery power is still available but not enough to support high-power devices, so as to meet the emergency lighting needs of users in special scenarios, has become an urgent problem to be solved. Utility Model Content

[0006] The purpose of this application is to provide an electric electrode structure assembly to solve the problem of the single function of traditional battery racks.

[0007] To achieve the above objectives, the technical solution adopted in this application is as follows: An electrode structure assembly is provided, which is used to be mounted on a battery holder bracket. The battery holder includes a positive terminal and a negative terminal for electrical connection with an electrical appliance. The electrode structure assembly includes: a lighting assembly connected to the bracket and electrically connected to the positive and negative terminals of the battery holder; and a switch assembly electrically connected to the lighting assembly, which controls the current flow between the lighting assembly and the battery holder. Specifically, turning on the switch assembly enables current flow between the positive and negative terminals of the lighting assembly and the battery holder, thus turning on the lighting; turning off the switch assembly disconnects the current flow between the positive and negative terminals of the lighting assembly and the battery holder, thus turning off the lighting.

[0008] As a preferred embodiment, the switch assembly includes a first switch and a second switch, the first switch being disposed on the bracket and the second switch being disposed on the lighting assembly, the first switch being for manual control, the first switch controlling the on / off state of the second switch, and the on / off state of the second switch controlling the current flow between the lighting assembly and the battery holder.

[0009] As another preferred embodiment, the first switching element includes a first conductive element, a second conductive element, and a third conductive element, which are interconnected. The first conductive element is movably connected to the bracket. One end of the second conductive element is connected to the first conductive element, and the other end of the second conductive element is connected to the third conductive element. The third conductive element is used to communicate with the positive terminal of the battery holder. By moving the first conductive element, the second conductive element is compressed, so that the first conductive element touches the second switching element to realize the on / off switching of the lighting component.

[0010] Preferably, the first conductive element is a positive copper cap, and the battery holder includes a first usage state and a second usage state. The first usage state is when the battery holder is assembled into an electrical appliance for use, and the second usage state is when the battery holder is used for lighting alone. In the first usage state, the positive copper cap, together with the second and third conductive elements, enables the power transmission of the battery in the battery holder. In the second usage state, when the battery holder is moved, the positive copper cap contacts the second switching element to complete the on / off switching of the lighting component.

[0011] More preferably, the first conductive member, the second conductive member, and the third conductive member are axially arranged along the extension direction of the battery holder and are consistent with the moving direction of the first conductive member.

[0012] Preferably, when the battery holder is in a first usage state, the movable travel of the first conductive element is recorded as a first distance; when the battery holder is in a second usage state, the movable travel of the first conductive element is recorded as a second distance; wherein, the second distance is greater than the first distance.

[0013] Preferably, the electric electrode structure assembly further includes an assembly housing connected to the bracket, the assembly housing having an assembly cavity, and the lighting assembly placed within the assembly cavity.

[0014] Further preferably, the assembly housing is a transparent structure.

[0015] Further preferably, one end of the switch assembly is electrically connected to the positive electrode of the battery holder, and correspondingly, the electrode end structure assembly further includes a conductive plate, which extends from the negative electrode end of the battery holder along the surface of the support and is then electrically connected to the switch assembly.

[0016] Preferably, the lighting assembly includes a printed circuit board assembly and LED beads, the LED beads being connected to the printed circuit board assembly, and the printed circuit board assembly being disposed around the third conductive element.

[0017] Compared with the prior art, the beneficial effects of this application are as follows:

[0018] The lighting component in the electric pole structure assembly has a relatively low power. When the battery in the battery holder can no longer provide stable power to high-power headlamps or other devices, the remaining power of the battery can be used to power the low-power lighting component to achieve the lighting function. This provides convenience for users in situations where lighting is needed, such as viewing objects or performing operations in dark environments. By adding the electric pole structure assembly, the practicality and functionality of the battery holder are increased. In other words, during actual operation, after the battery holder is removed from the headlamp or other electrical appliances, the lighting component built into the battery holder can still illuminate for a period of time, which can be used for emergency purposes.

[0029] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0031] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0032] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0033] In a preferred embodiment, see Figures 1 to 9This application provides an electrode structure assembly 5, which is used to mount onto a bracket 10 of a battery holder 1. The battery holder 1 includes a positive electrode 2 and a negative electrode 3 for electrical connection with an electrical appliance 60. Preferably, the electrode structure assembly 5 is positioned at the positive electrode of the battery holder 1. The electrode structure assembly 5 includes: a lighting assembly 30 connected to the bracket 10 and electrically connected to the positive electrode 2 and negative electrode 3 of the battery holder 1; and a switch assembly 400 electrically connected to the lighting assembly 30 to control the current flow between the lighting assembly 30 and the battery holder 1. When the switch assembly 400 is turned on, the current flow between the lighting assembly 30 and the positive electrode 2 and negative electrode 3 of the battery holder 1 is connected, turning on the lighting. When the switch assembly 400 is turned off, the current flow between the lighting assembly 30 and the positive electrode 2 and negative electrode 3 of the battery holder 1 is disconnected, turning off the lighting.

[0034] As a preferred option, specific participants Figures 3 to 6 The switch assembly 400 includes a first switch 40 and a second switch 50. The first switch 40 is placed on the bracket 10, and the second switch 50 is placed on the lighting assembly 30. The first switch 40 is for manual control and controls the on / off of the second switch 50. The on / off of the second switch 50 controls the current flow between the lighting assembly 30 and the battery holder 1.

[0035] As another preferred embodiment, the first switching element 40 includes a first conductive element 41, a second conductive element 42, and a third conductive element 43, which are interconnected. The first conductive element 41 is movably connected to the bracket 10. One end of the second conductive element 42 is connected to the first conductive element 41, and the other end of the second conductive element 42 is connected to the third conductive element 43. The third conductive element 43 is used to communicate with the positive terminal 2 of the battery holder 1. Moving the first conductive element 41 compresses the second conductive element 42, so that the first conductive element 41 touches the second switching element 50 to realize the switching on and off of the lighting assembly 30.

[0036] The electric electrode structure assembly 5 also includes an assembly housing 20, which is connected to the bracket 10. The assembly housing 20 has an assembly cavity 21, and the lighting assembly 30 is placed in the assembly cavity 21.

[0037] For further optimization, see Figure 6 One end of the switch assembly 400 is electrically connected to the positive electrode 2 of the battery holder 1. Correspondingly, the electrode end structure assembly 5 also includes a guide plate 70. The guide plate 70 is led out from one end of the negative electrode 3 of the battery holder 1 along the surface of the bracket 10 and then electrically connected to the switch assembly 400. The arrangement of the guide plate 70 facilitates the connection of the lighting assembly 30 to the negative electrode 3 of the battery holder 1 through the second switch member 50.

[0038] It should be noted that the battery holder 1 in this application can also be used in headlamps, flashlights, or camping lights to provide power to these devices. The size of the battery holder 1 can be customized according to actual usage. The battery holder 1 in this application is assembled from two parts: a bracket 10 and a battery 4. The axial height of the bracket 10 in the related technology is relatively low for 18650 or 21700 lithium batteries to accommodate 3*AAA batteries. However, a longer spring needs to be installed inside the bracket 10. When the battery holder 1 in the related technology is used with 3*AAA batteries, the axial height of the bracket 10 is relatively short, so it is relatively loose when installed in some headlamps or camping lights. In addition, due to the increased internal resistance of the product, a higher luminous flux cannot be obtained. Therefore, the bracket 10 in this application preferably has an increased axial height to maintain the same height as the 18650 or 21700 lithium batteries, resulting in better interchangeability and a more reasonable structure for the bracket 10.

[0039] The bracket 10 in this application is used to accommodate and place the battery 4, providing a stable placement space for the battery 4, preventing it from shaking or shifting during use, ensuring the stability and safety of the battery 4, and facilitating the normal performance of the battery 4. The bracket 10 has a negative terminal 3 and a positive terminal 2, clearly defining the positive and negative connection positions of the battery 4, facilitating correct electrical connections with other components. Furthermore, the bracket 10 in this application has three battery compartments to accommodate up to three batteries 4, and see details [see details]. Figure 8 Three batteries 4 are connected in series in the bracket 10.

[0040] Preferably, the assembly housing 20 in this application is located at one end of the positive electrode 2 of the bracket 10 and has an assembly cavity 21. On the one hand, it can protect the positive electrode copper cap from rusting and corrosion caused by the external environment. On the other hand, it provides a space and platform for the installation of other components, such as the lighting component 30, making the assembly of each component more compact and reasonable, and enhancing the overall integrity of the device. Furthermore, preferably, the assembly housing 20 is a transparent structure, which facilitates the light transmission of the lighting component 30 and provides better lighting effect.

[0041] The lighting component 30 includes a printed circuit board assembly 31 and LED beads 32. The LED beads 32 are connected to the printed circuit board assembly 31 and are evenly distributed on the surface of the printed circuit board assembly 31, which is located around the third conductive element 43. Specifically, the LED beads 32 are low-power LED beads that provide auxiliary lighting. The printed circuit board assembly 31 is a PCBA (Printed Circuit Board Assembly). Pressing the positive copper cap causes the limiting flange 411 of the positive copper cap to abut against the second switch on the PCBA, thus turning the second switch on or off and controlling the state of the LED beads 32. The printed circuit board assembly 31 integrates control commands, thereby controlling the state of the LED beads 32 by the number of times the second switch is turned on, enabling the LED beads 32 to be constantly lit, off, flashing, or changing their light color.

[0042] Meanwhile, since the LED 32 in this application has a relatively low power, it can use the remaining power of the battery 4 to provide lighting function after the battery 4 can no longer provide stable power to high-power headlamps and other devices. This provides convenience for users in situations where lighting is needed, such as viewing objects or performing operations in dark environments. It increases the practicality and functionality of the battery holder 1. In other words, in actual operation, after the battery holder 1 is removed from the headlamp or other device, the battery holder 1 can still be lit for a period of time by the built-in lighting component 30, which can be used for emergency situations.

[0043] By placing the lighting component 30 inside the assembly cavity 21, the space inside the assembly housing 20 is made reasonable, making the structure of the entire battery rack 1 more compact and optimizing the space utilization of the battery rack 1. The device will not become too large or bulky due to the addition of the lighting function, thus maintaining the simplicity and portability of the device.

[0044] Among them, see Figures 3 to 5 The first switch 40 is connected to the assembly housing 20. In specific operation, by pressing the first conductive part 41 (positive copper cap), the first conductive part 41 touches and abuts against the second switch 50, so that the second switch 50 is turned on to complete the conduction between the lighting component 30 and the positive and negative terminals in the battery holder 1, thereby realizing the lighting function of the lamp 32. The operation is simple and convenient, and users can quickly turn the lighting function on or off according to actual needs, which improves the convenience and flexibility of use.

[0045] The first conductive element 41 is movably connected to the assembly housing 20, giving the switch a certain degree of flexibility and operability during operation, allowing for easy circuit connection and disconnection via a pressing action. The second conductive element 42 is connected to both the first conductive element 41 and the third conductive element 43, forming a complete current path. This ensures that the battery holder 1 in this application can be normally used in devices such as headlamps, and this connection method can adapt to different pressing degrees and angles to a certain extent, ensuring reliable circuit connection under various conditions and guaranteeing the normal operation of the lighting assembly 30.

[0046] The third conductive element 43 is used to connect with the positive electrode 2, and it is also connected to the integrated end of the surrounding spring. This means that the positive electrodes of all three batteries 4 converge at the third conductive element 43. The compression of the second conductive element 42 controls the conduction between the first conductive element 41 and the lighting assembly 30. This design enables precise control of the circuit's continuity. Only when the second conductive element 42 is compressed to a certain extent by pressing the first conductive element 41 will the first conductive element 41 connect to the lighting assembly 30, avoiding mis-conduction caused by slight touches or other external factors, thus improving the accuracy and stability of the switch control.

[0047] The second conductive element 42 is placed inside the assembly cavity 21, making reasonable use of the space inside the assembly housing 20, and making the assembly of the entire first switch element 40 with other components more compact. This layout can organically combine the various parts of the first switch element 40 with other structures inside the assembly housing 20, reducing the overall volume of the device, making the battery holder 1 more compact and portable, and also helping to improve the overall structural strength and stability of the device.

[0048] This first switch element 40 structure, composed of multiple conductive elements, allows for the individual installation and connection of each conductive element during installation, reducing installation difficulty and improving assembly efficiency. During later maintenance, if a conductive element malfunctions, it can be easily disassembled for inspection, repair, or replacement without affecting the normal operation of other components, thus reducing maintenance costs and difficulty. Simultaneously, the multiple conductive elements increase the stability and reliability of the current path, reduce resistance and contact resistance, lower energy loss in the circuit, and improve the electrical performance of the battery holder 1. Furthermore, this structure can withstand larger currents, ensuring a stable power supply for the lighting assembly 30 during operation, extending the lifespan of the lighting assembly 30, and improving the overall performance of the device.

[0049] As another preferred embodiment, the first conductive element 41 is specifically a positive electrode copper cap. The battery holder 1 includes a first usage state and a second usage state. In the first usage state, the battery holder 1 is assembled into the electrical appliance 60 for use, and in the second usage state, the battery holder 1 is used for lighting alone. In the first usage state, the positive electrode copper cap, together with the second conductive element 42 and the third conductive element 43, enables the power transmission of the battery 4 within the battery holder 1. In the second usage state, the positive electrode copper cap is moved, and the positive electrode copper cap contacts the second switch 50 to switch the lighting assembly 30 on and off. Furthermore, since this application integrates the first conductive element 41 into a positive electrode copper cap, the number of connection points and interfaces between components is reduced, lowering the risk of malfunctions caused by loose connections or poor contact due to external switches. As a single component, the positive electrode copper cap has better stability and reliability within the battery holder 1.

[0050] The first conductive element 41 is specifically set as a positive copper cap, which reduces the structure of setting the first conductive element 41 separately, making the overall structure of the battery rack 1 simpler. The positive copper cap serves as both a component connecting the battery 4 to the electrical appliance 60 and a component controlling the conduction of the lighting component 30, avoiding the use of too many parts, reducing the complexity of the structure, and helping to improve production efficiency and product reliability.

[0051] By reducing the number of independent first conductive elements 41, space can be saved during the design and manufacturing process of the battery rack 1, making it easier to accommodate more other functional components in the future, thus improving the space utilization of the battery rack 1 and making the product more competitive.

[0052] In the second usage state, in some other embodiments, the second switch 50 can be omitted. By pressing the positive copper cap, that is, by pressing the first conductive member 41 for a long time, the circuit is turned on and the lighting function is realized by pressing it against the lighting component 30. This conduction method adopts the control method of pressing to turn on the light and releasing to turn off the light, that is, there is no need to perform complicated operations to switch the usage state of the battery holder 1.

[0053] Furthermore, the first conductive element 41, i.e., the positive copper cap, the second conductive element 42, and the third conductive element 43 are axially arranged along the extension direction of the battery holder 1 and are consistent with the moving direction of the first conductive element 41.

[0054] The axial arrangement allows current to be transmitted in a straight line between the three conductors, with a direct and smooth path. This reduces bends and detours in the current transmission process, thereby reducing resistance, improving current transmission efficiency, reducing power loss, and ensuring that the battery rack 1 can provide power to the lighting assembly 30 or other electrical appliances 60 more efficiently.

[0055] The three conductive components are arranged axially, allowing for sequential installation during assembly. This facilitates operation, improves assembly efficiency, and reduces assembly difficulty. Furthermore, this arrangement clearly defines the positional relationship of each conductive component, making it easier for workers to position and install them during assembly, reducing the possibility of assembly errors and improving product assembly quality and consistency.

[0056] The movement direction of the first conductive element 41 is consistent with the axial direction of the conductive element, which ensures that the movement trajectory of the first conductive element 41 is stable and smooth during pressing or operation, without any jamming, deviation, or sticking. This facilitates accurate compression and release of the second conductive element 42, thereby precisely controlling the opening and closing of the lighting assembly 30, improving the operating feel and reliability of the first switch 40. The axial arrangement allows the three conductive elements to work together in a straight line, making the force transmission more direct and uniform. When subjected to external forces, such as vibration or collision of the battery holder 1, the conductive elements can better share the external force, making them less prone to deformation or damage, thus enhancing the stability and reliability of the entire battery holder 1 structure and extending the service life of the battery holder 1.

[0057] The battery holder 1 has a first usage state and a second usage state. In the first usage state, it can be installed and used with the electrical appliance 60, and in the second usage state, it can be used for lighting independently. This greatly expands the functionality of the battery holder 1. Users do not need to carry separate lighting equipment. When lighting is needed, the battery holder 1 can meet the requirements, improving the practicality and use value of the battery holder 1 and providing users with more convenience.

[0058] Further, see Figures 4 to 5 When the battery holder 1 is in the first use state, the movable stroke of the first conductive member 41 is recorded as the first distance X1. When the battery holder 1 is in the second use state, the movable stroke of the first conductive member 41 is recorded as the second distance X2. The second distance X2 is greater than the first distance X1.

[0059] Different usage states may correspond to different working requirements, and the movable stroke can be used to adapt to different working modes. For example, in the first usage state, only a small first distance X1 is needed for the first conductive member 41 to move to fix the battery holder 1 relative to the headlamp or other equipment, so as to realize the power output function of the battery holder 1; while in the second usage state, the first conductive member 41 may need to have a larger movable stroke, that is, it needs to move a second distance X2 to realize the light emission requirement of the battery holder 1 itself and complete the switching function. The different stroke settings ensure that the first usage state and the second usage state do not interfere with each other, thus ensuring the stability of the battery holder 1 in this application.

[0060] Furthermore, a larger second movable stroke makes it possible to achieve multi-level conduction or control. For example, in the second use state, the first conductor 41 can move a greater distance to contact multiple different conductors or circuit nodes in sequence, thereby realizing the hierarchical conduction of the circuit or the sequential activation of different functions, which facilitates the functional expansion and refined control of the battery rack 1. For example, the lamp beads 32 in the lighting assembly 30 can achieve flashing or color changing through hierarchical conduction.

[0061] This design facilitates future upgrades and expansions of the battery rack 1. If new functions need to be added or improvements to the battery rack 1 are required in the future, the larger movable stroke in the second usage state can be used to easily add new conduction paths or functional modules without making large-scale changes to the overall structure of the battery rack 1, thus reducing the cost and difficulty of product upgrades.

[0062] Meanwhile, the battery holder 1 in this application integrates the first conductive element 41 with the positive copper cap, without setting up an external switch. It should be noted that the external switch is an additional module independent of the power transmission path, while the first conductive element 41 in this application, i.e., the positive copper cap, is both the core electrode for power transmission and the physical carrier of the switching function. This dual-function integration is reflected in the indivisibility of the structure: the positive copper cap realizes the dynamic switching between power transmission and lighting control through the difference in axial movement stroke (first distance X1 / second distance X2). Its movement path is deeply coupled with the mechanical structure of the bracket 10, such as the physical constraint of the stroke by the limiting flange 411, while the external switch cannot achieve coaxial dynamic reuse with the power transmission path.

[0063] Among them, the axially arranged three-conductor structure forms an irreplaceable synergistic effect. The axial series design of the first conductor 41 (positive copper cap), the second conductor 42, and the third conductor 43 produces the following technical effects: the axial stacking of the three conductors makes the volume of the first switch 40 only 1 / 3 of that of a traditional side switch, and the function can be expanded by utilizing the original structural space of the positive copper cap. That is, the second conductor 42 can be embedded into the hollow part of the positive copper cap, while the external switch will inevitably lead to volume expansion.

[0064] From the perspective of state switching logic, the physical interlock between the power delivery mode and the lighting mode in the battery rack 1 is achieved through the difference in movable travel (first distance X1 / second distance X2), avoiding accidental operation. That is, the lighting mode of the battery rack 1 in this application will not be accidentally activated when assembled to the appliance 60. At the same time, it breaks the traditional design paradigm that the electrodes must be statically connected, allowing key power components to also have control functions.

[0065] Specifically, since the primary function of the battery holder 1 is to facilitate the transfer of the battery 4, enabling the battery holder 1 to be used on external electrical appliances 60, the battery slots that different electrical appliances 60 can accommodate the battery holder 1 may have slight differences in length due to manufacturing errors. For example, in some electrical appliances 60 with shorter battery slots, a positive copper cap that can be telescopically installed to a certain extent as described in this application is used, and a metal spring provides thrust to ensure the assembly stability of the battery holder 1 fitting into the battery slot.

[0066] In a further preferred embodiment, the positive electrode copper cap is hollowed out, and the second conductive element 42 is embedded inside the positive electrode copper cap, and the second conductive element 42 is attached to the inner wall end of the positive electrode copper cap to ensure the expansion and contraction stability of the second conductive element 42.

[0067] The second conductive element 42 is embedded in the positive copper cap, making the connection between the two tighter and more stable. Compared with the simple external connection method, it can better resist the effects of external forces such as pulling and vibration, reducing the risk of loosening or falling off due to external forces. It ensures that the electrical connection remains stable during the use of the battery rack 1, reducing the probability of failure caused by connection problems.

[0068] Furthermore, the second conductive element 42 is attached to the inner wall end of the positive copper cap, providing stable support and guidance for the extension and retraction of the second conductive element 42. During the process of pressing the positive copper cap to turn the lighting assembly 30 on or off, the second conductive element 42 can smoothly extend and retract along the contact surface of the inner wall end of the positive copper cap, avoiding shaking, offset, or jamming, thereby ensuring the operational stability and reliability of the first switching element 40 and extending its service life. Specifically, the second conductive element 42 is a metal spring structure.

[0069] This configuration makes the electrical connection between the second conductive element 42 and the positive copper cap better and more stable. Because the two are closely fitted, the contact area is relatively large and the contact is more uniform, which can effectively reduce the contact resistance, reduce the loss of electrical energy during transmission, and improve the overall electrical performance of the battery holder 1.

[0070] Further preferred, the third conductive member 43 is a barrel-shaped structure, and both ends of the third conductive member 43 are provided with flange structures 431. Specifically, the three batteries 4 are connected in series to the third conductive member 43 and are connected through the flange structures 431. At the same time, the flange structure 431 near the assembly housing 20 abuts against the printed circuit board assembly 31 so that the third conductive member 43 is fixed and the third conductive member 43 plays a connecting role.

[0071] The barrel-shaped structure itself has good structural strength and stability, and can better withstand forces from all directions. Compared with other simple shapes, it is less prone to deformation. Since the third conductive element 43 needs to play a docking role, the flanged structure 431 at both ends can increase the contact area during the conduction process, making the third conductive element 43 less likely to loosen or fall off, and ensuring that the electrical connection remains stable and reliable during the use of the battery rack 1.

[0072] Preferably, the end of the second conductive member 42 near the end of the third conductive member 43 is provided with a protrusion structure 421, the end of the second conductive member 42 is attached to the third conductive member 43, and the protrusion structure 421 extends into the third conductive member 43.

[0073] The protruding structure 421 extends into the third conductive element 43, increasing the contact points and contact area between the second conductive element 42 and the third conductive element 43, making the electrical connection between them more stable and reliable. During the use of the battery holder 1, it can effectively avoid poor contact problems caused by vibration, shaking, etc., ensuring the stability of current transmission and reducing the probability of circuit failure.

[0074] The protruding structure 421 serves a positioning and guiding function, helping the second conductive element 42 to accurately align with the third conductive element 43 during assembly, ensuring their relative positional accuracy and facilitating installation and debugging. During use, it also ensures that the second conductive element 42 moves along the mating direction of the protrusion and the third conductive element 43 during extension, retraction, or movement, preventing offset or wobbling and enhancing the stability and reliability of the entire first switching element 40. Simultaneously, the mating of the protrusion and the third conductive element 43 increases the mechanical connection strength between the two elements, enabling them to work together better under external forces, sharing the load and reducing the likelihood of relative displacement or detachment. This contributes to improving the structural stability of the entire battery rack 1, especially when the battery rack 1 may be subjected to vibration, impact, or other external forces, effectively protecting the integrity of the electrical connections.

[0075] Furthermore, the positive copper cap is provided with a limiting flange 411 to abut against the assembly housing 20. The limiting flange 411 prevents the positive copper cap from coming out of the assembly housing 20. When the battery holder 1 is in the second use state, pressing the positive copper cap will allow the limiting flange 411 to abut against the lighting component 30 to complete the conduction.

[0076] The limiting flange 411 can prevent the positive copper cap from coming out of the assembly housing 20, ensuring that the positive copper cap remains in a fixed position in the assembly structure of the battery rack 1 and will not fall off from the assembly housing 20 due to vibration, external pulling, etc., thereby ensuring the integrity and stability of the battery rack 1 structure, enabling the entire device to work normally. Moreover, by limiting the position of the positive copper cap, the connection between the positive copper cap and the assembly housing 20 is more reliable. During the use of the battery rack 1, it can better withstand various external forces, reduce the risk of failure caused by loose connection, and improve the overall durability of the battery rack 1.

[0077] When the battery holder 1 is in its second operating state, pressing the positive copper cap causes the limiting flange 411 to accurately abut against the printed circuit board assembly 31 to complete the conduction. This design enables precise electrical connection control, ensuring accurate control of the conduction process and guaranteeing a reliable electrical connection when lighting is required. This allows the lighting assembly 30 to operate normally and improves the accuracy and repeatability of the conduction operation.

[0078] Meanwhile, the contact between the limiting flange 411 and the lighting component 30 provides stable contact pressure, ensuring a stable electrical connection between the positive copper cap and the printed circuit board component 31, and reducing the occurrence of problems such as poor contact or intermittent conduction.

[0079] Meanwhile, in other embodiments, see Figure 7 This application also discloses a battery holder 1 with a separate switch assembly 400 to control the lighting assembly 30. That is, the switch assembly 400 can also be connected to the bracket 10 independently. The switch assembly 400 is separate from the positive copper cap and is not integrated with it. However, similarly, the part protruding from the surface of the bracket 10 in the switch assembly 400 is the first switch element 40. By pressing the first switch element 40, the second switch element 50 on the lighting assembly 30 is triggered, thereby connecting the circuit to the lighting assembly 30 and completing the lighting of the LED bead 32. Figure 9 The circuit diagram for the battery holder 1 is applicable to the battery holder 1 in any of the above embodiments.
