Description

Technical Field

[0001] This application relates to the field of power tool technology, and more specifically, to a voltage switching component, a battery pack, and an electrode holder. Background Technology

[0002] Currently, most removable battery packs on the market use a single voltage platform design, meaning their output voltage is fixed and cannot be switched or adjusted according to the needs of the load device. In actual products, different brands or models of power tools often use different voltage platforms (such as 20V, 40V, etc.), making it difficult for traditional battery packs to be universally interchangeable between multiple voltage systems. Users need to configure corresponding battery packs for devices with different voltage platforms, increasing usage costs and management complexity.

[0003] Therefore, related technologies have proposed mechanical voltage switching components to enable the battery pack to output two different voltages. Internally, an elastic element releases its elastic force to move the switching element, switching the battery pack from a high-voltage output state to a low-voltage output state. If the battery pack is to be kept in a high-voltage state for an extended period, the elastic element needs to be in a compressed state for a long time. Therefore, when switching to a low-voltage state is required, the elastic element is prone to failure. The elastic force it generates may not be sufficient to move the switching element to the predetermined distance, or the elastic force may be too weak to achieve the voltage conversion, ultimately causing a battery pack voltage switching failure.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0036] Related technologies have proposed mechanical voltage switching components to enable battery packs to output two different voltages. Internally, an elastic element releases its elastic force to move the switching element, switching the battery pack from a high-voltage output state to a low-voltage output state. If the battery pack is to be kept in a high-voltage state for an extended period, the elastic element needs to be in a compressed state for a prolonged period. Therefore, when switching to a low-voltage state is required, the elastic element is prone to failure. The elastic force it generates may not be sufficient to move the switching element to the predetermined distance, or the elastic force may be too weak to achieve the voltage conversion, ultimately causing a battery pack voltage switching failure.

[0037] To address the aforementioned technical problems, embodiments of this application provide a voltage switching component, a battery pack, and an electrode holder.

[0038] Reference Figure 1 , Figure 2 as well as Figure 3 As shown in the embodiment of this application, the voltage switching component is configured on the circuit board 10 of the battery pack and includes a switching component 20 and a trigger component 30; one end of the trigger component 30 is connected to the switching component 20.

[0039] Reference Figure 4 As shown, in one embodiment of this application, the portion of the trigger 30 away from the switching member 20 is provided with a first switching part 301 and a second switching part 302; the first switching part 301 is driven by a thrust to move the switching member 20 along a straight line from a first position to a second position; or, the second switching part 302 is driven by a thrust to move the switching member 20 along a straight line from a second position to a first position.

[0040] It should be noted that the switching element 20 achieves voltage output switching by moving along a straight line between the first position and the second position.

[0041] Specifically, refer to Figure 2 as well as Figure 3As shown, a first connector 200 and a second connector 201 are provided on the switching member 20; a connector 100 is provided on the circuit board 10; the connector 100 is located between the first connector 200 and the second connector 201; the switching member 20 is driven to move in a straight line, the second connector 201 moves away from the connector 100, the first connector 200 moves closer to the connector 100 and plugs into the connector 100, so that the battery pack outputs a first voltage; or, the first connector 200 moves away from the connector 100, the second connector 201 moves closer to the connector 100 and plugs into the connector 100, so that the battery pack outputs a second voltage; the first voltage is greater than the second voltage.

[0042] It should be noted that, in this embodiment of the application, one end of the trigger member 30 is connected to the switching member 20, and the other end is provided with a first switching part 301 and a second switching part 302. The first switching part 301 and the second switching part 302 are respectively used to push the switching member 20 from different directions, thereby realizing bidirectional position switching.

[0043] Specifically, when the first switching unit 301 is pushed, it drives the switching member 20 to move along a straight line from the first position to the second position, so that the voltage switching component switches from the second voltage to the first voltage.

[0044] When the second switching part 302 is pushed, it drives the switching member 20 to return from the second position to the first position along a straight line, so that the voltage switching component switches the first voltage to the second voltage.

[0045] The technical effects that the embodiments of this application can produce are as follows:

[0046] Firstly, it can solve the failure problem caused by long-term compression of the elastic element. This application's embodiment, by introducing a first switching unit 301 and a second switching unit 302, avoids relying solely on the elastic element to maintain the voltage switching mechanism. When the elastic element remains compressed for a long time, and its failure prevents the switching element 20 from returning from the second position to the first position, the second switching unit 302 can be driven to achieve rapid switching, improving the system's reliability and durability.

[0047] Secondly, it improves the stability and accuracy of voltage switching. This embodiment uses a highly stable mechanical switching mechanism. By applying a thrust to the first switching unit 301 or the second switching unit 302, the position change of the switching element 20 can be controlled more precisely, ensuring accurate completion of each voltage switch. This not only improves the quality of the electrical connection but also reduces the failure rate caused by poor contact.

[0048] Third, users can easily and reliably switch between different voltage output modes with simple operations, without worrying about the status or performance of internal components. This intuitive operation enhances the user experience and makes the device easier to manage.

[0049] Please combine Figure 4 and Figure 5 As an optional implementation, the first switching part 301 is disposed at the end of the trigger 30 away from the switching part 20; the second switching part 302 includes a recessed structure 303 located on one side of the trigger 30, and the opening of the recessed structure 303 is away from the circuit board 10.

[0050] It should be noted that in this embodiment, the first switching unit 301 is located at the end of the trigger member 30 away from the switching member 20. That is to say, when the user needs to switch from a low-voltage output state to a high-voltage output state, the switching member 20 can be moved by applying a thrust to this end.

[0051] The second switching unit 302 in this embodiment includes a recessed structure 303 located on one side of the trigger 30, the opening of which faces away from the circuit board 10. This design allows users to achieve a switching in the opposite direction, i.e., returning from a high-voltage output state to a low-voltage output state, by applying a pushing force to the recessed structure 303.

[0052] Specifically, the user can use a tool or finger to insert into the recessed structure 303 to apply a pushing force to the side wall of the recessed structure 303, thereby driving the trigger 30 to move.

[0053] The technical effects that the embodiments of this application can produce are as follows:

[0054] In this embodiment, the first switching part 301 is located at the end of the trigger 30 furthest from the switching part 20, allowing the user to intuitively identify how to perform the voltage switching operation. Its recessed structure 303 serves as the second switching part 302, providing a clear operating point and facilitating the user to apply a reverse thrust to complete the switching action in the opposite direction. The design of the recessed structure 303 may also increase the friction of the contact surface of the finger or tool, making the operation more stable and reliable. Therefore, this design in this embodiment improves the convenience and accuracy of operation.

[0055] In this embodiment, by designing the second switching part 302 as a recessed structure 303 and having the opening direction opposite to the circuit board 10, the circuit board 10 can effectively prevent the operation of inserting fingers or tools into the recessed structure 303 from being obstructed, making the operation more convenient.

[0056] Reference Figure 5 As shown, in one optional embodiment, the first switching part 301 has a first abutting surface 304; the first abutting surface 304 is perpendicular to the linear movement direction of the switching member 20; the inner wall of the recessed structure 303 has a second abutting surface close to the first abutting surface 304, and the first abutting surface 304 is parallel to the second abutting surface.

[0057] Furthermore, this application embodiment explicitly defines that the first switching part 301 is provided with a first abutting surface 304 perpendicular to the linear movement direction of the switching member 20. When the user applies a pushing force to the first abutting surface 304, the switching member 20 can be driven to move along its predetermined linear path.

[0058] A second abutment surface is provided on the inner wall of the recessed structure 303 near the first abutment surface 304. This second abutment surface is parallel to the first abutment surface 304, ensuring that the thrust in the opposite direction can also act on the switching member 20 in the same way, thereby realizing bidirectional voltage switching.

[0059] The beneficial effects that the embodiments of this application can produce are:

[0060] This embodiment of the application, by designing the first abutment surface 304 perpendicular to the linear movement direction of the switching member 20, ensures that the thrust applied to it can be directly converted into a linear displacement of the switching member 20. This reduces thrust decomposition losses and improves operational accuracy and efficiency. Similarly, the second abutment surface is parallel to the first abutment surface 304, ensuring that the same linear displacement effect is produced when thrust is applied from the other side, guaranteeing the consistency and reliability of bidirectional switching.

[0061] Since both the first contact surface 304 and the second contact surface are planar and parallel to each other, this helps to provide a stable contact surface, avoiding jamming or slippage caused by uneven contact points. This design enhances the mechanical stability and durability of the entire voltage switching assembly.

[0062] Preferably, the projected portions of the first switching part 301 and the second switching part 302 overlap on a plane perpendicular to the moving direction of the switching member 20, thereby making the trigger member 30 structurally compact.

[0063] Reference Figure 1 , Figure 6 As shown, as an optional implementation, it also includes a mounting box 40 disposed on the surface of the circuit board 10, a switching member housed in the mounting box 40, and a trigger member 30 penetrating through the mounting box 40; the circuit board 10 is provided with a plurality of plug-in terminals 60; the plurality of plug-in terminals 60 are arranged at intervals along the direction perpendicular to the movement of the switching member 20; the portion of the trigger member 30 away from the switching member 20 and located outside the mounting box 40 is arranged in the middle of the plurality of plug-in terminals 60. It should be noted that there is only one trigger member 30 in this embodiment. The first switching part 301 and the second switching part 302 are disposed on the portion of the trigger member 30 away from the switching member 20 and located outside the mounting box 40.

[0064] It should be noted that the mounting box 40 in this embodiment is fixed on the surface of the circuit board 10 to accommodate and protect the voltage switching components, specifically including components such as the switching component 20, the first plug-in component 200, and the second plug-in component 201.

[0065] Reference Figure 1 As shown, multiple plug terminals 60 are arranged at intervals along a direction perpendicular to the movement direction of the switching member 20. It should be noted that these plug terminals 60 are used to form a conductive connection with the first plug member 200 or the second plug member 201, thereby realizing different voltage outputs or inputs.

[0066] In this embodiment, the trigger element 30 is arranged in the middle of multiple plug terminals 60, and this embodiment includes only one trigger element 30. This means that the switching element 20 can be controlled to move between two positions by a single trigger element 30, thereby achieving voltage switching.

[0067] The beneficial effects that the embodiments of this application can produce are as follows:

[0068] In this embodiment, the trigger element 30 is positioned in the center of the plurality of plug-in terminals 60, resulting in a more compact and rational overall layout. This design not only effectively utilizes limited space but also avoids unnecessary structural complexity, helping to reduce the overall size of the battery pack and adapt to the needs of more application scenarios.

[0069] Since there is only one trigger 30, the user only needs to apply a pushing force to the trigger 30 to complete the voltage switching operation. This simplified design reduces the difficulty of operation for users, improves the convenience and accuracy of operation, and reduces the risk of misoperation.

[0070] In this embodiment, the trigger 30 is located in the middle of the plurality of plug terminals 60, which ensures that it can uniformly transmit force to the switching element 20 when subjected to a pushing force, avoiding jamming or displacement of the switching element 20 due to uneven force distribution. This design enhances the mechanical stability and durability of the entire voltage switching assembly.

[0071] In this embodiment, a trigger 30 is positioned in the middle of multiple plug terminals 60. Whether switching from a high-voltage state to a low-voltage state, or vice versa, the entire process can be controlled by the same trigger 30. This ensures consistency and reliability during bidirectional position switching and avoids performance differences caused by different triggering mechanisms.

[0072] Reference Figure 1 , Figure 6 As shown, in one optional implementation, the mounting box 40 has a support frame 50 near the plug-in terminal 60; the support frame 50 includes a positioning plate 501 spaced parallel to the circuit board 10, and the positioning plate 501 has positioning holes 502. (Refer to...) Figure 7 As shown, the plug terminal 60 has pins 601, at least a portion of which engage through the positioning hole 502 and are connected to the circuit board 10.

[0073] The support frame 50 of this embodiment is provided on the side of the mounting box 40 near the plug-in terminal 60 to provide additional mechanical support and positioning function.

[0074] The support frame 50 in this embodiment includes a positioning plate 501, which is parallel to and spaced apart from the circuit board 10. The positioning plate 501 is provided with positioning holes 502 for precisely fixing the position of the plug-in terminals 60, ensuring that they are correctly aligned and connected to the corresponding positions on the circuit board 10.

[0075] The effects that the embodiments of this application can produce are:

[0076] This application ensures that the plug terminal 60 can be accurately inserted into the predetermined position through the positioning hole 502, which helps to firmly connect the pin 601 to the circuit board 10. Therefore, the embodiment of this application can avoid poor contact problems caused by misalignment or loosening of the plug terminal 60, and improve the electrical connection stability of the system.

[0077] The support frame 50 in this embodiment provides additional mechanical support, enabling the plug-in terminal 60 to remain stable when subjected to external forces. Therefore, this embodiment not only enhances the mechanical strength of the entire assembly but also extends its service life.

[0078] Furthermore, the design of the positioning hole 502 simplifies the assembly process of the plug terminal 60, allowing operators to quickly and accurately insert the pin 601 into the corresponding positioning hole 502, reducing assembly time and errors. This design is particularly advantageous for mass production, helping to improve production efficiency.

[0079] Reference Figure 5 , Figure 6 As shown, in one optional implementation, the support frame 50 is provided with a first guide groove 505 in the middle, and the extension direction of the first guide groove 505 is consistent with the moving direction of the switching member 20; the trigger member 30 has a first guide portion 305 that is connected to the first guide groove 505.

[0080] It should be noted that the first guide groove 505 is located in the middle of the support frame 50, and its extension direction is consistent with the movement direction of the switching member 20. This guide groove provides a clear movement path for the trigger member 30, ensuring that the trigger member 30 can slide smoothly in a straight direction. The first guide portion 305 is located on the trigger member 30 and is connected to the first guide groove 505 on the support frame 50. When the trigger member 30 is subjected to a thrust, the first guide portion 305 slides along the first guide groove 505, thereby guiding the trigger member 30 and the switching member 20 connected to it to move in a predetermined direction.

[0081] The effects that the embodiments of this application can produce are:

[0082] In this embodiment, the cooperative design of the first guide groove 505 and the first guide portion 305 ensures that the trigger 30 can only move along a predetermined straight path, greatly avoiding lateral deviation or wobbling. This precise guiding mechanism improves the operational accuracy during voltage switching and reduces insertion failures or poor contact caused by mechanical displacement deviations.

[0083] The guide structure in this embodiment makes the trigger 30 and the switching element 20 more stable during movement, maintaining good working condition even under frequent use or under large external forces. This not only extends the service life of the components but also reduces the risk of failure due to wear or loosening, enhancing the stability and durability of the system.

[0084] Reference Figure 5 As shown, in one optional implementation, the first guide portion 305 and the second switching portion 302 are located on both sides of the extension direction of the trigger member 30.

[0085] The first guide portion 305 is located on one side of the extension direction of the trigger member 30. Specifically, the first guide portion 305 is located on the side of the extension direction closer to the circuit board 10, and is connected to the first guide groove 505 on the support frame 50 to ensure that the trigger member 30 can move along a predetermined straight path.

[0086] The second switching unit 302 is located on the other side of the extension direction of the trigger 30. Specifically, the second switching unit 302 is located on the side of the extension direction away from the circuit board 10, and is used to receive thrust to realize the switching from the low-voltage output state to the high-voltage output state.

[0087] It should be noted that, in this embodiment, the first guide portion 305 and the second switching portion 302 are distributed on both sides of the trigger member 30, ensuring the separation of the thrust application point and the guiding mechanism. This avoids the complexity and potential failure risks caused by a single structure simultaneously undertaking both guiding and switching functions. This design improves the stability of system operation and reduces the possibility of failure due to mechanical stress concentration.

[0088] Reference Figure 1 , Figure 3 As shown, as an optional implementation, it also includes an elastic member 70. The switching member 20 is provided with a connecting portion 206. The trigger member 30 is connected to the first side of the connecting portion 206, and the elastic member 70 abuts against the second side of the connecting portion 206. When the switching member 20 moves along a straight line from the first position to the second position, the elastic member 70 compresses and stores elastic potential energy.

[0089] It should be noted that when the switching element 20 moves from the first position to the second position, the elastic element 70 is compressed and stores energy. Once the externally applied thrust disappears or decreases, the elastic element 70 releases the stored energy, pushing the switching element 20 back to the initial first position. This design achieves an automatic reset function, enabling bidirectional switching without additional operating steps and simplifying the user's operation process.

[0090] It should be noted that in one usage scenario, the elastic element 70 pushes the switching element 20 from the second position back to the first position. When the elastic element 70 fails, the user can push the switching element 20 from the second position back to the first position through the second switching part 302 to ensure reliable switching.

[0091] Reference Figure 8 As shown, this application embodiment provides a battery pack, including a housing 90, a circuit board 10, and the voltage switching component described above; a first socket 901 and a second socket 902 are provided on the housing 90; the first socket 901 corresponds to the position of the plug-in terminal 60, so that the insertion end of the plug-in terminal 60 is exposed; the second socket 902 corresponds to the trigger part 30, so that the first switching part 301 and the second switching part 302 are exposed.

[0092] It should be noted that the design of the first socket 901 ensures that the plug terminal 60 can be easily connected to external devices without disassembling the battery pack casing or other complicated steps. This greatly improves the user's ease of operation, especially important when frequently changing or debugging equipment. The design of the second socket 902 allows the user to directly apply force to the first switching unit 301 and the second switching unit 302 through the opening on the housing 90 to complete the voltage switching operation.

[0093] Reference Figure 9 As shown, this application embodiment provides an electrode holder, including an electrode holder body 80 that engages with the aforementioned battery pack; the electrode holder body 80 is provided with a plurality of electrode pieces 801 that are inserted into the plug-in terminals 60; the electrode holder body 80 is provided with a trigger rod 802, which can be inserted into a second socket 902 and abuts against the first switching part 301 of the trigger member 30.

[0094] It should be noted that the electrode holder body 80 in this embodiment can be disposed on a power tool. When the electrode holder body 80 of the power tool is plugged into the battery pack, the battery pack can supply power to the power tool. Similarly, the electrode holder body 80 can also be disposed in a charger, and the charger can charge the battery pack when connected to the battery pack through the electrode holder.

[0095] It should be noted that the above electrode holder is suitable for installation on high-voltage power tools; for example, when installed on a power tool with a working voltage of 40V, when the electrode holder is plugged into the battery pack, the trigger rod 802 can be directly inserted into the second socket 902 of the battery pack and abut against the first switching part 301 of the trigger 30, automatically realizing the conversion from low voltage to high voltage.

[0096] It should be noted that the electrode holder of a power tool with a low operating voltage does not need to be equipped with a trigger rod 802, and the automatic switching from high voltage to low voltage can be achieved by using the elastic element 70.

[0097] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
