Description

Technical Field

[0001] The present application relates to the technical field of electrical connectors, and in particular to a battery rack. Background Art

[0002] With the development of battery racks, batteries are widely used as a power source in daily life and work scenarios, providing power support for various devices. The main function of traditional battery racks is to accommodate and fix batteries, ensuring a stable electrical connection between batteries and devices to achieve normal operation of the devices. For example, in devices such as headlights, the battery rack is responsible for placing batteries and powering the headlights.

[0003] However, existing battery racks have many limitations that need to be addressed. On the one hand, the single function problem is prominent, and it can only meet the battery's carrying and basic power supply needs. When the battery power is remaining but not enough to support the normal operation of the equipment, the battery rack loses its function and cannot provide further convenience for users. For example, when the battery power drops and cannot provide stable power for high-power headlights, the headlights go out. At this time, the traditional battery rack has no other use, resulting in a waste of resources.

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

[0005] Therefore, how to solve the problem that traditional battery racks have a single function and how to continue to provide lighting functions when the battery power is remaining but not enough to support high-power equipment, so as to meet the user's emergency lighting needs in special scenarios has become an urgent problem to be solved. Summary of the invention

[0006] The purpose of the present application is to provide a battery rack to solve the problem of single function of traditional battery racks.

[0032] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0033] In a preferred embodiment, see Figures 1 to 9The present application document provides a battery rack 1, including a bracket 10, the bracket 10 is used to assemble a battery 4, and the battery rack 1 includes a positive electrode 2 and a negative electrode 3 for electrically connecting to an electrical appliance 60, and the battery rack 1 also includes: a lighting component 30, the lighting component 30 is arranged on the bracket 10, and the lighting component 30 is electrically connected to the positive electrode 2 and the negative electrode 3 of the battery rack 1; a switch component 400, the switch component 400 is electrically connected to the lighting component 30, and the switch component 400 is used to control the current on and off between the lighting component 30 and the battery rack 1; wherein, the switch component 400 is turned on to realize the current conduction between the lighting component 30 and the positive electrode 2 and the negative electrode 3 of the battery rack 1, and the lighting is turned on, and the switch component 400 is turned off to disconnect the current conduction between the lighting component 30 and the positive electrode 2 and the negative electrode 3 of the battery rack 1, and the lighting is turned off.

[0034] As a preferred option, specifically participate in Figures 3 to 6 The switch assembly 400 includes: a first switch component 40 and a second switch component 50. The first switch component 40 is placed on the bracket 10, and the second switch component 50 is placed on the lighting assembly 30. The first switch component 40 is used for manual control. The first switch component 40 controls the on and off of the second switch component 50. The on and off of the second switch component 50 controls the on and off of the current between the lighting assembly 30 and the battery rack 1.

[0035] As another preferred embodiment, the first switch component 40 includes: a first conductive component 41, a second conductive component 42 and a third conductive component 43, which are mutually conductive, the first conductive component 41 is movably connected to the bracket 10, one end of the second conductive component 42 is connected to the first conductive component 41, and the other end of the second conductive component 42 is connected to the third conductive component 43, and the third conductive component 43 is used to communicate with the positive electrode 2 of the battery rack 1; wherein, the first conductive component 41 is moved, and then the second conductive component 42 is compressed, so that the first conductive component 41 touches the second switch component 50 to realize the on and off of the lighting assembly 30.

[0036] Preferably, an assembly shell 20 is provided at the end of the bracket 10 , the assembly shell 20 is provided with an assembly cavity 21 , and the lighting assembly 30 is placed in the assembly cavity 21 .

[0037] For further preference, see Figure 6 One end of the switch assembly 400 is electrically connected to the positive electrode 2 of the battery rack 1, and correspondingly, one end of the negative electrode 3 of the battery rack 1 is led out along the surface of the bracket 10 to extend the guide piece 70 to be electrically connected to the switch assembly 400. The setting of the guide piece 70 facilitates the lighting assembly 30 to be connected to the negative electrode of the battery rack 1 through the second switch component 50.

[0038] It should be noted that the battery rack 1 in the present application document can also be used in headlamps, flashlights or camping lights to provide power support for the above-mentioned equipment, and the size of the battery rack 1 can be set according to actual usage. The battery rack 1 in the present application document is assembled from a bracket 10 and a battery 4, and the axial height of the bracket 10 in the related art is relatively low for adapting to 18650 or 21700 lithium batteries, so as to adapt to 3*AAA batteries. However, a longer spring is required in the bracket 10. When the battery rack 1 in the related art is equipped with 3*AAA batteries for use, due to the short axial height of the bracket 10, it is relatively loose when installed in some headlamps or camping lights, and due to the increased internal resistance of the product, a relatively high luminous flux cannot be obtained. Therefore, the bracket 10 in the present application document preferably increases the axial height to maintain the same height as the 18650 or 21700 lithium battery, so as to achieve better interchangeability and a more reasonable structure of the bracket 10.

[0039] The bracket 10 in the present application document is used to accommodate and place the battery 4, and can provide a stable placement space for the battery 4, so that the battery 4 is not easy to shake or shift during use, ensuring the stability and safety of the battery 4, which is conducive to the normal performance of the battery 4, and the bracket 10 is provided with a negative electrode 3 and a positive electrode 2, which clearly defines the positive and negative connection positions of the battery 4, and is convenient for correct electrical connection with other components, and the bracket 10 in the present application document is provided with three battery compartments to assemble at most three batteries 4, and see specifically Figure 8 , three batteries 4 are arranged in series in the bracket 10.

[0040] Preferably, the assembly shell 20 in the present application document is arranged at one end of the positive electrode 2 of the bracket 10 and is provided with an assembly cavity 21, which can protect the positive electrode copper cap on the one hand and prevent it from rusting, corroding, etc. due to the influence of the external environment, and on the other hand, provide an installation space and platform for other components, such as the lighting assembly 30, so that the assembly of each component is more compact and reasonable, and the integrity of the device is enhanced. It is further preferred that the assembly shell 20 is a transparent structure, which is convenient for the lighting assembly 30 to transmit light and provide a better lighting effect.

[0041] The lighting assembly 30 includes a printed circuit board assembly 31 and lamp beads 32. The lamp beads 32 are connected to the printed circuit board assembly 31. The lamp beads 32 are evenly distributed on the surface of the printed circuit board assembly 31, and the printed circuit board assembly 31 is arranged around the third conductive member 43. The lamp beads 32 are specifically a low-power lamp bead 32, which plays a role of auxiliary lighting. The printed circuit board assembly 31 is a PCBA. The positive copper cap is pressed so that the limit flange 411 of the positive copper cap abuts against the second switch provided on the PCBA. The second switch is turned on or off to control the state of the lamp beads 32. The printed circuit board assembly 31 is integrated with a control instruction, so that the state of the lamp beads 32 is controlled by the number of times the second switch is turned on, so that the lamp beads 32 are always on, turned off, or flashing, or the light color is converted.

[0042] At the same time, since the power of the lamp beads 32 in the present application document is relatively small, after the battery 4 is unable to provide stable power for equipment such as high-power headlights, the last remaining power of the battery 4 can be used to realize the lighting function, providing convenience for users in some occasions where lighting is required, such as viewing objects and performing operations in a dark environment, etc., thereby increasing the practicality and functionality of the battery rack 1. That is, in actual operation, after the battery rack 1 is taken out from equipment such as headlights, the battery rack 1 can also light up for a period of time through the built-in lighting component 30, which can be used for emergency.

[0043] Placing the lighting assembly 30 in the assembly cavity 21 rationally utilizes the space inside the assembly shell 20, making the structure of the entire battery rack 1 more compact, optimizing the space utilization of the battery rack 1, and preventing the device from becoming too large or bloated due to the addition of the lighting function, thereby maintaining the simplicity and portability of the device.

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

[0045] The first conducting member 41 is movably connected to the assembly housing 20, so that the switch has certain flexibility and operability when operating, and can easily realize the conduction and disconnection of the circuit by pressing. The second conducting member 42 is respectively connected to the first conducting member 41 and the third conducting member 43, forming a complete current path, ensuring that the battery rack 1 in this application document can be normally used in equipment such as headlights, and this connection method can adapt to different pressing degrees and angles to a certain extent, ensuring that the circuit can be reliably conducted in various situations, ensuring the normal operation of the lighting assembly 30.

[0046] The third conductive member 43 is used to communicate with the positive electrode 2, and the third conductive member 43 is connected to the integrated end of the surrounding spring, that is, the positive electrodes of the three batteries 4 are all gathered to the third conductive member 43, and the conduction between the first conductive member 41 and the lighting assembly 30 is controlled by the compression of the second conductive member 42. This design can achieve precise control of the circuit conduction. Only when the first conductive member 41 is pressed to compress the second conductive member 42 to a certain extent, the first conductive member 41 and the lighting assembly 30 will be connected, avoiding misconduction caused by slight touch or other external factors, and improving the accuracy and stability of switch control.

[0047] The second conducting member 42 is placed in the assembly cavity 21, which reasonably utilizes the space inside the assembly housing 20, making the assembly of the entire first switch member 40 and other components more compact. This layout can organically combine the various parts of the first switch member 40 with other structures in the assembly housing 20, reduce the overall volume of the device, make the battery rack 1 more compact and portable, and also help to improve the overall structural strength and stability of the device.

[0048] This structure of the first switch element 40 composed of multiple conductive parts can install and connect each conductive part separately during installation, which reduces the difficulty of installation and improves assembly efficiency. During later maintenance, if a conductive part has a problem, it can be easily disassembled for inspection, repair or replacement without affecting the normal operation of other parts, reducing maintenance costs and difficulties. At the same time, the setting of multiple conductive parts can increase the stability and reliability of the current path, reduce resistance and contact resistance, reduce energy loss in the circuit, and improve the electrical performance of the battery rack 1. At the same time, this structure can also withstand larger currents, ensuring that the lighting assembly 30 can obtain a stable power supply when working, extending the service life of the lighting assembly 30, and improving the performance of the entire device.

[0049] As another preferred embodiment, the first conductive member 41 is specifically a copper cap of the positive electrode 2, and the battery rack 1 includes a first use state and a second use state. The first use state is that the battery rack 1 is assembled to the electrical appliance 60 for use, and the second use state is that the battery rack 1 is used alone for lighting; wherein, when the battery rack 1 is in the first use state, the copper cap of the positive electrode 2 cooperates with the second conductive member 42 and the third conductive member 43 to realize the power transmission of the battery 4 in the battery rack 1, and when the battery rack 1 is in the second use state, the copper cap of the positive electrode 2 is moved, and the copper cap of the positive electrode 2 contacts the second switch 50 to complete the switching of the lighting assembly 30. And because the first conductive member 41 is integrated into the copper cap of the positive electrode in the present application document, the connection points and interfaces between the components are reduced, and the risk of failure caused by loose connection or poor contact caused by the external connection of other switch components is reduced. As an integral component, the copper cap of the positive electrode has better stability and reliability in the battery rack 1.

[0050] The first conductive member 41 is specifically configured as a positive electrode copper cap, thereby reducing the need for a separate first conductive member 41 and making the overall structure of the battery rack 1 more concise. The positive electrode copper cap is used as both a component for connecting the battery 4 to the electrical appliance 60 and a component for controlling the conduction of the lighting assembly 30, thereby avoiding the use of too many components, reducing the complexity of the structure, and being beneficial to improving production efficiency and product reliability.

[0051] Since the independent first conductive member 41 is reduced, a certain amount of space can be saved during the design and manufacturing process of the battery rack 1, which is convenient for accommodating more other functional components in the future, thereby 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, and the positive copper cap is pressed, that is, the first conductive member 41 is long pressed to make it abut against the lighting assembly 30 to complete the circuit conduction and realize the lighting function. This conduction method adopts a control method of long 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 rack 1.

[0053] Furthermore, the first conductive member 41 , ie, the positive electrode copper cap, the second conductive member 42 and the third conductive member 43 are axially arranged along the extension direction of the battery rack 1 , and are consistent with the moving direction of the first conductive member 41 .

[0054] The axial setting enables the current to be transmitted between the three conductive parts in a straight line direction, and the path is direct and smooth, reducing the bending and detours in the current transmission process, thereby reducing the resistance, improving the current transmission efficiency, reducing the power loss, and ensuring that the battery rack 1 can more efficiently provide power to the lighting assembly 30 or other electrical appliances 60.

[0055] The three conducting parts are arranged along the axial direction, and can be installed in sequence during assembly, which is convenient for operation, helps to improve assembly efficiency and reduce assembly difficulty. At the same time, this arrangement makes the positional relationship of each conducting part clear, which is convenient for workers to locate and install during the assembly process, reduces the possibility of assembly errors, and improves the assembly quality and consistency of the product.

[0056] The moving direction of the first conductive member 41 is consistent with the axial direction of the conductive member, which can ensure that the movement trajectory of the first conductive member 41 is stable and smooth during pressing or operation, and there will be no jamming, offset or jamming. This is conducive to the accurate compression and release operation of the second conductive member 42, and then accurately controls the opening and closing of the lighting assembly 30, improves the operating feel and reliability of the first switch member 40, and the axial setting enables the three conductive members to work together in a straight line, and the force transmission is more direct and uniform. When subjected to external forces, such as vibration or collision of the battery rack 1, the conductive members can better bear the external force together, and are not easily deformed or damaged, thereby enhancing the stability and reliability of the entire battery rack 1 structure and extending the service life of the battery rack 1.

[0057] The battery rack 1 has a first use state and a second use state. In the first use state, it can be assembled to the electrical appliance 60 for use, and in the second use state, it can be used for lighting alone, which greatly expands the function of the battery rack 1. Users do not need to carry additional separate lighting equipment. When lighting is needed, the battery rack 1 can meet the needs, which improves the practicality and use value of the battery rack 1 and provides more convenience for users.

[0058] For further information, see Figures 4 to 5 When the battery rack 1 is in the first use state, the movable stroke of the first conductive member 41 is recorded as the first distance X1, and when the battery rack 1 is in the second use state, the movable stroke of the first conductive member 41 is recorded as the second distance X2; wherein the second distance X2 is greater than the first distance X1.

[0059] Among them, different use states may correspond to different work requirements, and the movable stroke is used to adapt to different work modes. For example, in the first use state, the first conductive member 41 only needs to move a small first distance X1 to fix the battery rack 1 relative to the headlight and other equipment to achieve the power transmission function of the battery rack 1; while in the second use state, the first conductive member 41 may need to have a larger movable stroke, that is, it needs to move the second distance X2 to achieve the lighting requirements of the battery rack 1 itself and complete the switch function. The setting of different strokes makes the first use state and the second use state not interfere with each other, ensuring the stability of the use of the battery rack 1 in this application document.

[0060] At the same time, the larger second movable stroke can provide the possibility of realizing multi-level conduction or control. For example, in the second use state, the first conductive member 41 moves a larger distance to contact with multiple different conductive members or circuit nodes in sequence, thereby realizing the hierarchical conduction of the circuit or the sequential activation of different functions, which provides convenience for the functional expansion and refined control of the battery rack 1. For example, the lamp beads 32 in the lighting assembly 30 can flash or change colors after hierarchical conduction.

[0061] This design facilitates future upgrades and expansions of the battery rack 1. If new functions need to be added or the battery rack 1 needs to be improved in the future, the larger movable travel in the second use state can be used to conveniently add new conduction paths or functional modules without making large-scale changes to the overall structure of the battery rack 1, thereby reducing the cost and difficulty of product upgrades.

[0062] At the same time, the battery rack 1 in this application document integrates the first conductive member 41 and the positive copper cap without setting an external switch. It should be noted that the external switch is an additional module independent of the power transmission path, and the first conductive member 41 in this application document, namely the positive copper cap, is both the core electrode of power transmission and the physical carrier of the switch function. This dual-function integration is reflected in the structural indivisibility: the positive copper cap realizes the dynamic switching of power transmission and lighting control through the axial movement stroke difference (first distance X1 / second distance X2), and its movement path is deeply coupled with the mechanical structure of the bracket 10, such as the physical constraint of the stroke by the limit flange 411, and the external switch cannot realize coaxial dynamic multiplexing with the power transmission path.

[0063] Among them, the axially arranged three-conducting component structure forms an irreplaceable synergistic effect, and the axial series design of the first conductive component 41 (positive copper cap), the second conductive component 42, and the third conductive component 43 produces the following technical effects: the axial stacking of the three conductive components makes the volume of the first switch component 40 only 1 / 3 of the traditional lateral switch, and the original structural space of the positive copper cap is used to achieve functional expansion, that is, the second conductive component 42 can be embedded in the hollow part of the positive copper cap, and the external switch will inevitably lead to volume expansion.

[0064] From the perspective of state switching logic, the physical interlocking of the power transmission mode and the lighting mode in the battery rack 1 is achieved through the movable travel difference (first distance X1 / second distance X2) to avoid misoperation, that is, the lighting mode of the battery rack 1 in this application document will not be accidentally activated when assembled to the electrical appliance 60. At the same time, the traditional design paradigm that electrodes must be statically connected is broken, so that key power components can also have control functions.

[0065] Specifically, since the first main function of the battery rack 1 is to realize the transfer of the battery 4 so that the battery rack 1 can be used on an external electrical appliance 60, there are processing errors in the battery slots of different electrical appliances 60 that can accommodate the battery rack 1, which will cause slight differences in the lengths of the battery slots provided in different electrical appliances 60. For example, in some electrical appliances 60 with shorter battery slots, the positive copper cap that can be retracted to a certain extent in the present application document is used to provide thrust through a metal spring to ensure the assembly stability of the battery rack 1 when it is embedded in the battery slot.

[0066] Further preferably, the positive copper cap is hollowed out, the second conductive member 42 is embedded in the positive copper cap, and the second conductive member 42 is fitted with the inner wall end of the positive copper cap to ensure the telescopic stability of the second conductive member 42.

[0067] Among them, the second conductive member 42 is embedded in the positive copper cap, making the connection between the two tighter and more stable. Compared with simple external connection methods, it can better resist the influence of external forces such as pulling and vibration, and reduces the risk of loose connection or falling off due to external forces, ensuring 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 member 42 is fitted with the inner wall end of the positive copper cap, which can provide stable support and guidance for the expansion and contraction of the second conductive member 42. In the process of pressing the positive copper cap to turn on or off the lighting assembly 30, the second conductive member 42 can smoothly expand and contract along the fitting surface of the inner wall end of the positive copper cap to avoid shaking, offset or jamming, thereby ensuring the operational stability and reliability of the first switch 40 and extending its service life. Specifically, the second conductive member 42 is a metal spring structure.

[0069] This arrangement makes the electrical connection between the second conductive member 42 and the positive electrode copper cap better and more stable. Since 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 electric energy during transmission, and improve the overall electrical performance of the battery rack 1.

[0070] Further preferably, the third conductive member 43 is a barrel-shaped structure, and flange structures 431 are provided at both ends of the third conductive member 43. Specifically, the three batteries 4 are connected in series to the third conductive member 43, and are docked through the flange structure 431. At the same time, the flange structure 431 close to the side of the assembly shell 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 docking role.

[0071] The barrel-shaped structure itself has good structural strength and stability, can better withstand forces from all directions, and is less likely to deform than other simple shapes. Since the third conductive member 43 needs to play a docking role, the flange structure 431 at both ends can increase the contact area during the conduction process, making the third conductive member 43 not easy to loosen or fall off, ensuring that the electrical connection always remains stable and reliable during the use of the battery rack 1.

[0072] Preferably, a protruding structure 421 is provided at an end of the second conductive member 42 close to the third conductive member 43 , the end of the second conductive member 42 is in contact with the third conductive member 43 , and the protruding structure 421 extends into the third conductive member 43 .

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

[0074] The protrusion structure 421 can play a role in positioning and guiding. During the assembly process, it can help the second conductive member 42 to accurately dock with the third conductive member 43, ensure the relative position accuracy of the two, and facilitate installation and debugging. During use, it can also ensure that the second conductive member 42 moves along the matching direction of the protrusion and the third conductive member 43 when it is extended or moved, avoiding deviation or shaking, and enhancing the stability and reliability of the entire first switch member 40. At the same time, the matching of the protrusion and the third conductive member 43 increases the mechanical connection strength between the second conductive member 42 and the third conductive member 43, so that they can work better together when subjected to external forces, jointly withstand external forces, and are not prone to relative displacement or falling off. This helps to improve the structural stability of the entire battery rack 1, especially when the battery rack 1 may be subjected to external forces such as vibration and collision, and can effectively protect the integrity of the electrical connection.

[0075] Furthermore, the positive copper cap is provided with a limiting flange 411 to abut against the assembly shell 20, and the limiting flange 411 prevents the positive copper cap from falling out of the assembly shell 20, and when the battery rack 1 is in the second use state, the positive copper cap is pressed to abut against the lighting assembly 30 through the limiting flange 411 to complete conduction.

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

[0077] When the battery rack 1 is in the second use state, when the positive copper cap is pressed, the limit flange 411 can accurately abut against the printed circuit board assembly 31 to complete the conduction. This design can achieve precise electrical connection control and precise control of the conduction function, ensuring that when lighting is needed, the electrical connection can be reliably established, so that the lighting assembly 30 can work normally, and the accuracy and repeatability of the conduction operation are improved.

[0078] At the same time, the abutment between the limiting flange 411 and the lighting assembly 30 can provide a stable contact pressure, ensuring a stable electrical connection between the positive copper cap and the printed circuit board assembly 31, and reducing the occurrence of problems such as poor contact or intermittent conduction.

[0079] Meanwhile, in other embodiments, see Figure 7 , the application document also discloses a battery rack 1 in which a switch assembly 400 is provided to control the lighting assembly 30, that is, the switch assembly 400 can also be connected to the bracket 10 separately, and the switch assembly 400 is separated from the positive copper cap and is not integrated with the positive copper cap. However, similarly, the switch assembly 400 protrudes from the surface of the bracket 10 is the first switch member 40, and the second switch member 50 provided on the lighting assembly 30 is triggered by pressing the first switch member 40, so that the circuit connects the lighting assembly 30, and the lamp bead 32 is lit.
