Description

Technical Field

[0001] This utility model relates to the field of power generation devices, and in particular to a power generation device. Background Technology

[0002] In some electrical systems, the power extraction device, as a key component for introducing electrical energy, typically includes a housing and power extraction terminals for contacting conductive terminals inside the conductive column. By engaging the power extraction terminals of the power extraction device with the conductive terminals inside the conductive column, a stable electrical connection is established, thereby enabling a continuous power supply to the electrical equipment.

[0003] However, most existing power-gathering devices adopt plug-in or crimp-type structures. Some power-gathering devices need to be accurately installed at designated positions on conductive columns to achieve electrical connection, which limits the installation location of the power-gathering devices and reduces the flexibility of their layout, making it difficult to meet the diverse needs for power-gathering locations in different scenarios. Other power-gathering devices, although they can obtain power from multiple locations at will, require the design of complex locking structures, resulting in complex structures and high costs. Utility Model Content

[0004] The main objective of this invention is to provide a power supply device that aims to solve at least one of the aforementioned technical problems.

[0005] To achieve the above objectives, the present invention proposes a power-collecting device for use with a conductive column. The conductive column includes a column body and two conductive terminals. The column body is provided with a power-collecting groove, and the two conductive terminals extend along a first direction and are spaced apart within the power-collecting groove along a second direction. The power-collecting device includes: case; Two power terminals are inserted into the housing. Each power terminal includes a first conductive part and a second conductive part that are bent and connected. The first conductive part is used to electrically connect to an external power source. The two second conductive parts extend in a direction away from each other and at least partially protrude from the housing. The power-generating device has a first state in which the second conductive portion extends along the first direction and a second state in which the second conductive portion extends along the second direction; in the first state, the two second conductive portions are used to maintain a distance from the corresponding conductive terminal; in the second state, the two second conductive portions are used to abut against the corresponding conductive terminal to be electrically connected to the conductive terminal. The housing can rotate relative to the conductive post in a third direction to allow the power-generating device to switch between the first state and the second state.

[0006] In one embodiment, the power-generating device further includes a positioning member having a positioning groove extending through its two opposite sides. A first positioning structure is provided between the positioning groove and the housing, so that the housing can extend into the positioning groove when the power-generating device is in the first state, and forms a stop for the housing when the housing is rotated to a position corresponding to the power-generating device being in the second state.

[0007] In one embodiment, the first positioning structure includes two stop portions disposed in the positioning groove and two abutment portions disposed on the outer wall of the housing. The two stop portions are spaced apart and each has a connected stop surface and a stepped surface. The two stop surfaces are staggered in the first direction. The included angle formed by the two stepped surfaces is the same as the included angle formed by the two abutment portions. In the second state, the abutment portion abuts against the stepped surface.

[0008] In one embodiment, the housing includes a first shell segment, a second shell segment, and a third shell segment connected in sequence. The second conductive portion is connected to the first shell segment. The first shell segment is flush with the outer side wall of the second shell segment in its minor axis direction and protrudes from the outer side wall of the second shell segment in its major axis direction. The outer peripheral wall of the third shell segment protrudes from the outer peripheral wall of the second shell segment. The abutting portion is provided on the side of the third shell segment facing the first shell segment.

[0009] In one embodiment, the positioning member has clearance openings on both sides of the first shell segment in the second direction, and in the second state, the two second conductive parts protrude from the corresponding clearance openings.

[0010] In one embodiment, the positioning member has grooves on both sides of the second housing segment corresponding to the second direction, the grooves extending along the first direction, and the grooves are used to slide and adapt to the edge of the opening of the power taking slot.

[0011] In one embodiment, the positioning member has a clearance groove formed on one side of the positioning groove in the axial direction corresponding to the third shell section, and the third shell section is provided with a marking portion protruding from its outer peripheral wall, at least a portion of the marking portion being located in the clearance groove.

[0012] In one embodiment, the housing is provided with a slot, and the power supply device further includes a rotating handle. The rotating handle includes an intersecting mounting part and a gripping part. The mounting part is provided with a wire-passing groove passing through one side of the mounting part away from the gripping part. The side of the mounting part away from the gripping part is also provided with a plug-in part that is adapted to be inserted into the slot.

[0013] In one embodiment, the housing includes two shell portions joined together, each shell portion forming two spaced-apart receiving grooves, each receiving groove including a first groove segment and a second groove segment, the two first groove segments extending side by side, the two second groove segments extending side by side, a first conductive part mounted on the first groove segment, a second conductive part mounted on the second groove segment, and a second positioning structure provided between the two shell portions.

[0014] In one embodiment, the bottom of the first groove segment is provided with a limiting protrusion, and the first conductive part is provided with a limiting notch corresponding to the limiting protrusion, and the limiting protrusion is engaged in the limiting notch.

[0015] The technical solution of this utility model designs the power-taking terminal as a first conductive part and a second conductive part with a bent structure. During installation, the user can first insert the power-taking device into the power-taking groove of the conductive column in the first state. At this time, the second conductive part is kept at a distance from the conductive terminal in the power-taking groove, and the circuit between the conductive column and the power-taking device is not connected. Subsequently, by rotating the housing in a third direction, the second conductive part is changed from the first state extending in the first direction to the second state extending in the second direction, so that the second conductive part contacts and connects with the conductive terminal and forms a limiting abutment with the corresponding conductive terminal to prevent the power-taking device from accidentally exiting or rotating back in the non-operational state, thereby reliably locking the power-taking device in the second state.

[0016] Thus, the switching of the power-generating device's state is achieved through the rotational movement of the housing relative to the conductive column, allowing the power-generating device to quickly connect to the conductive column at any position along the first direction without relying on a specific installation positioning structure. This avoids the dependence on fixed installation positions for traditional plug-in or press-fit power-generating devices, improving the installation flexibility of the power-generating device. Furthermore, compared to multi-position power-generating solutions requiring complex locking mechanisms, this solution achieves circuit on / off control through simple mechanical rotation. The power-generating device of this invention has advantages such as easy operation, reliable connection, flexible power generation, compact structure, fewer parts, and low manufacturing cost.

[0024] This utility model proposes a power extraction device 10.

[0025] Please see Figures 1 to 5 and Figure 16 In one embodiment of this utility model, the power-collecting device 10 is used to cooperate with the conductive column 20. The conductive column 20 includes a column body 21 and two conductive terminals 23. The column body 21 is provided with a power-collecting groove 22. The two conductive terminals 23 extend along a first direction and are spaced apart in the power-collecting groove 22 along a second direction. The power-collecting device 10 includes a housing 100 and two power-collecting terminals 200. The two power-collecting terminals 200 are inserted into the housing 100. Each power-collecting terminal 200 includes a first conductive part 210 and a second conductive part 220 that are bent and connected. The first conductive part 210 is used to electrically connect to an external power source, and the two second conductive parts 220 are used to connect to an external power source. The portion 220 extends in a direction away from each other and at least partially extends out of the housing 100; wherein, the power-taking device 10 has a first state in which the second conductive portion 220 extends in a first direction and a second state in which the second conductive portion 220 extends in a second direction; in the first state, the two second conductive portions 220 are used to maintain a distance from the corresponding conductive terminal 23; in the second state, the two second conductive portions 220 are used to abut against the corresponding conductive terminal 23 to be electrically connected to the conductive terminal 23; the housing 100 is rotatable relative to the conductive post 20 in a third direction to switch the power-taking device 10 between the first state and the second state.

[0026] Specifically, under normal use, the first direction of the conductive post 20 is vertical, and the second direction is horizontal. Of course, in other usage scenarios, the first and second directions can be defined as other directions depending on the actual installation posture, such as the first direction being horizontal and the second direction being vertical. The third direction is the rotation direction of the housing 100, that is, the housing 100 rotates circumferentially around its rotation axis. When the power-generating device 10 is installed on the conductive post 20, this rotation axis is perpendicular to the plane formed by the first and second directions.

[0027] Please see Figure 9 and Figure 10 One of the two power terminals 200 is a positive terminal, used for electrical connection with the positive terminal of an external power source and the positive electrode plate in the conductive terminal 23; the other is a negative terminal, used for electrical connection with the negative terminal of an external power source and the negative electrode plate in the conductive terminal 23. Both power terminals 200 are installed inside the housing 100. Each power terminal 200 includes a first conductive portion 210 and a second conductive portion 220. The two first conductive portions 210 extend in parallel, used for direct connection to an external power source, or for electrical connection to an external power source via a wire or the like. The second conductive portion 220 is bent and connected to the first conductive portion 210 (i.e., the power terminal 200 is L-shaped), extending in a direction away from each other, and at least partially extending out of the housing 100, for contacting the conductive terminal 23.

[0028] The relationship between the distance L1 between the outermost ends of the two second conductive portions 220 in their extending direction, the spacing L2 between the two conductive terminals 23 in the second direction, the width L3 of the slot opening of the power-taking groove 22 in the second direction, and the width L4 of the second conductive portion 220 in the second direction satisfies L1 > L2 > L3 > L4. The power-taking device 10 has a first state and a second state; please refer to [reference needed]. Figure 4 In the first state, the two second conductive parts 220 extend away from each other along a first direction. Since L3 > L4, the two second conductive parts 220 can enter the power-taking slot 22 from the slot opening. Since L2 > L4, the two second conductive parts 220 entering the power-taking slot 22 maintain a distance from the corresponding two conductive terminals 23 on the conductive post 20 (i.e., the second conductive parts 220 and the corresponding conductive terminals 23 do not contact each other). The conductive terminals 23 and the power-taking terminals 200 have no electrical connection. At this time, the conductive post 20 and the power-taking device 10 are in a de-energized state. Please refer to [link to relevant documentation]. Figure 5In the second state, the two second conductive parts 220 extend away from each other along the second direction, L1>L2, so that the two second conductive parts 220 tightly abut against the corresponding conductive terminal 23. The conductive terminal 23 is electrically connected to the power-taking terminal 200. At this time, the conductive post 20 and the power-taking device 10 are in a conductive state, and the tight connection between the second conductive part 220 and the corresponding conductive terminal 23 makes the second conductive part 220 stuck between the two conductive terminals 23, so that the power-taking device 10 can be maintained in the second state.

[0029] Please see Figures 1 to 5 The housing 100 can rotate relative to the conductive post 20 along a third direction. During rotation, the second conductive part 220 of the power-taking terminal 200 changes direction, thereby switching from the first state to the second state. In the first state, the second conductive part 220 extends along the first direction, so that when it is inserted into the power-taking slot 22 of the conductive post 20, it can avoid the corresponding conductive terminal 23, maintaining a gap between them, which facilitates the initial positioning and installation of the device. In the first state, even if the power-taking device 10 is inserted into the power-taking slot 22, the conductive terminal 23 will not be energized, preventing accidental energization or short circuit. The conductive post 20 is only connected to the power supply when the user actively rotates the power-taking device 10 to the second state, thereby realizing a safe mechanism for rapid power extraction by rotation. The state switching can be completed with just a rotation action, without the need for additional pressing, pushing, pulling or tool assistance, improving the user experience. By using rotation to change the direction of the second conductive part 220, it cleverly achieves positioning upon insertion and energization upon rotation.

[0030] In one implementation, please refer to Figure 1 and Figure 2 The opening of the power-collecting slot 22 extends along a first direction and penetrates the surface of the column body 21 to form a sliding channel extending along the first direction. The power-collecting device 10 can be inserted into the power-collecting slot 22 at any position along the first direction in a first state. At this time, the two second conductive parts 220 extend along the first direction and are spaced apart from the two conductive terminals 23 provided in the power-collecting slot 22, without electrical connection. After insertion, by rotating the housing 100 along a third direction, the two second conductive parts 220 change from the state of extending along the first direction to the second state of extending along the second direction, so that they respectively limit and abut against the corresponding conductive terminals 23 to achieve reliable electrical connection. The limiting abutment between the two second conductive parts 220 and the conductive terminals 23 locks the power-collecting device 10 in the second state.

[0031] In this way, the power-generating device 10 can achieve electrical connection and mechanical positioning at any insertion position of the conductive column 20 along the first direction, without the need for pre-alignment with a specific slot or the setting of additional locking structures (such as buckles, spring locking pins, etc.), thus completing installation and power supply. This design not only simplifies the assembly operation and improves user convenience, but also reduces the number of parts and lowers manufacturing costs. At the same time, the electrical connection and limiting functions are integrated into the rotational movement, resulting in a simple and reliable overall structure.

[0032] In another implementation, please refer to Figure 3 The power-collecting slot 22 does not penetrate the surface of the column body 21. The surface of the column body 21 is provided with a socket, which is connected to the internal power-collecting slot 22, and the extension direction of the socket is consistent with the first direction. The power-collecting device 10 can be inserted into the power-collecting slot 22 through the socket in the first state. When the power-collecting device 10 is fully inserted, the housing 100 is rotated along the third direction, driving the two second conductive parts 220 to change from the state extending along the first direction to the second state extending along the second direction. During this conversion, the second conductive parts 220 unfold outward and form limiting contact with the corresponding conductive terminals 23, realizing a stable electrical connection and preventing the power-collecting device 10 from accidentally withdrawing or rotating back in the non-operating state, thereby reliably locking the power-collecting device 10 in the second state. In this way, the power-collecting device 10 can also be applied to conductive columns 20 with preset sockets, and the installation position is defined by the sockets, realizing quick insertion and power supply in a fixed position.

[0033] The technical solution of this utility model is to design the power-taking terminal 200 as a first conductive part 210 and a second conductive part 220 with a bent structure. During the installation process, the user can first insert the power-taking device 10 into the power-taking slot 22 of the conductive column 20 in the first state. At this time, the second conductive part 220 and the conductive terminal 23 in the power-taking slot 22 are kept apart, and the circuit between the conductive column 20 and the power-taking device 10 is not connected. Subsequently, by rotating the housing 100 in the third direction, the second conductive part 220 is changed from the first state extending in the first direction to the second state extending in the second direction, so that the second conductive part 220 contacts and connects with the conductive terminal 23, and forms a limiting abutment with the corresponding conductive terminal 23 to prevent the power-taking device 10 from accidentally exiting or rotating back in the non-operational state, thereby reliably locking the power-taking device 10 in the second state.

[0034] Thus, the state switching of the power-generating device 10 is achieved through the rotational movement of the housing 100 relative to the conductive post 20, enabling the power-generating device 10 to achieve rapid electrical connection at any position along the first direction of the conductive post 20, without relying on a specific installation positioning structure. This avoids the dependence of traditional plug-in or crimp-type power-generating devices 10 on fixed installation positions, improving the installation flexibility of the power-generating device 10. Furthermore, compared to multi-position power-generating solutions requiring complex locking mechanisms, this solution achieves circuit on / off control through simple mechanical rotation. The power-generating device 10 of this invention has advantages such as simple operation, reliable connection, flexible power generation, compact structure, fewer parts, and low manufacturing cost.

[0035] In one implementation, please refer to Figure 1 , Figure 2 and Figure 8 The power-generating device 10 also includes a positioning member 300. The positioning member 300 has a positioning groove 310 that passes through its two opposite sides. A first positioning structure is provided between the positioning groove 310 and the housing 100 so that the housing 100 extends into the positioning groove 310 when the power-generating device 10 is in the first state, and forms a stop for the housing 100 when the housing 100 rotates to a position corresponding to the power-generating device 10 being in the second state.

[0036] The positioning member 300 extends into the power-collecting slot 22 from its opening and can slide relative to the column body 21 in a first direction. The positioning member 300 has positioning grooves 310 penetrating its two opposite sides. When the power-collecting device 10 is in the first state, the housing 100 can extend into the positioning grooves 310 in the insertion direction to insert into the power-collecting slot 22. By sliding the positioning member 300 in the first direction, the positioning member 300 can drive the housing 100 and the power-collecting terminal 200 to slide together. When the housing 100 rotates to a predetermined position in the second state, the first positioning structure acts as a stop for the housing 100, preventing it from rotating under- or over-rotating, thereby ensuring that the two second conductive parts 220 can accurately and stably establish an electrical connection with the corresponding conductive terminals 23. The first positioning structure provides a clear sense of positioning during state switching of the power-collecting device 10, improving the intuitiveness and reliability of operation. Furthermore, when the housing 100 rotates to the second state, the clamping force between the second conductive part 220 and the conductive terminal 23 is at its maximum, and the conductive terminal 23 can firmly clamp the second conductive part 220, so that the power taking device 10 is locked in the second state. This can effectively prevent the connection from being disconnected due to vibration, external force or misoperation causing the housing 100 to rotate in the opposite direction, thus enhancing the stability and safety of the connection.

[0037] This embodiment achieves precise limiting of the rotation angle of the housing 100 by setting a first positioning structure between the positioning member 300 with positioning groove 310 and the housing 100. It provides clear feedback on the positioning position during rotation without the need for additional elastic latches or complex transmission mechanisms, effectively preventing incomplete or excessive rotation and ensuring the stable operation of the power-generating device 10 in the second state. Simultaneously, the positioning member 300 can be fixed to the conductive column 20 or the mounting structure, serving as a guide for the insertion and rotation of the power-generating device 10, further improving the accuracy and repeatability of installation.

[0038] For other implementations, please refer to Figure 2 Alternatively, the positioning element 300 can be omitted, and the power receiving device 10 can be directly inserted into the power receiving slot 22. Furthermore, a first positioning structure can be provided between the power receiving slot 22 and the housing 100.

[0039] In one implementation, please refer to Figures 7 to 9 , Figures 12 to 14 The first positioning structure includes two stop portions 320 disposed in the positioning groove 310 and two abutment portions 140 disposed on the outer wall of the housing 100. The two stop portions 320 are spaced apart and each has a stop surface 321 and a step surface 322 connected to each other. The two stop surfaces 321 are offset in a first direction. The included angle formed by the two step surfaces 322 is the same as the included angle formed by the two abutment portions 140. In the second state, the abutment portion 140 abuts against the step surface 322.

[0040] During the transition from the first state to the second state of the power-generating device 10, the housing 100 rotates relative to the positioning member 300 in a third direction, and the two abutment portions 140 on the housing 100 rotate accordingly. Since the two stop portions 320 are spatially misaligned, and the included angle between their stepped surfaces 322 is the same as the included angle between the abutment portions 140, when the housing 100 rotates to a predetermined angle, the two abutment portions 140 accurately fall into their corresponding stepped surfaces 322 positions and abut against them. At this time, the abutment surfaces provide radial restraint for the abutment portions 140, limiting the housing 100 from being inserted too deeply into the positioning groove 310, thus preventing the risk of misalignment between the second conductive portion 220 and the conductive terminal 23; the stepped surfaces 322 provide circumferential restraint for the abutment portions 140, limiting the housing 100 from continuing to rotate to prevent over-rotation, and also preventing incomplete rotation to prevent under-rotation, thereby ensuring that the second conductive portion 220 is accurately aligned with the conductive terminal 23 inside the conductive post 20 and achieves stable abutment and electrical connection. The misalignment design of the stop surface 321 in the first direction requires the housing 100 to rotate in a predetermined direction, thereby achieving unidirectional guidance of the rotation direction and preventing reverse misinstallation or reverse rotation from causing connection failure.

[0041] In other embodiments, only a first stop portion 320 and an abutment portion 140 may be provided. Alternatively, the abutment portion 140 may be provided in the positioning groove 310, and the stop portion 320 may be provided on the housing 100.

[0042] In one implementation, please refer to Figure 9 The housing 100 includes a first housing segment 110, a second housing segment 120, and a third housing segment 130 connected in sequence. A second conductive part 220 is connected to the first housing segment 110. The first housing segment 110 is flush with the outer side wall of the second housing segment 120 in its minor axis direction and protrudes from the outer side wall of the second housing segment 120 in its major axis direction. The outer peripheral wall of the third housing segment 130 protrudes from the outer peripheral wall of the second housing segment 120. An abutment part 140 is provided on the side of the third housing segment 130 facing the first housing segment 110.

[0043] The housing 100 includes a first housing segment 110, a second housing segment 120, and a third housing segment 130 connected sequentially along its length. A second conductive portion 220 is connected to the first housing segment 110 and extends outward from its end for contacting and conducting with the conductive terminal 23 inside the conductive post 20. The first housing segment 110 is flush with the outer wall of the second housing segment 120 along its short axis, ensuring a smooth surface of the housing 100 in this lateral direction and reducing interference between the first housing 100 and the inner wall of the positioning groove 310 during installation. Along its long axis, the first housing segment 110 protrudes from the outer wall of the second housing segment 120, forming a protruding area for accommodating or guiding the second conductive portion 220, ensuring that when the power taking device 10 is in the second state, the second conductive portion 220 has sufficient length to limit and abut against the conductive terminal 23. The outer peripheral wall of the third shell section 130 protrudes from the outer peripheral wall of the second shell section 120, forming a stepped outer contour. The abutment part 140 is provided on the side of the third shell section 130 facing the first shell section 110, and is used to cooperate with the stop part 320 on the positioning member 300 during the rotation of the shell 100 to realize the limit and stop of rotation into position.

[0044] In other embodiments, the first shell segment 110 may also be cylindrical, and the outer peripheral walls of the first shell segment 110, the second shell segment 120 and the third shell segment 130 are smoothly connected.

[0045] In one implementation, please refer to Figure 6 and Figure 14 The positioning member 300 has clearance openings 330 on both sides of the first shell section 110 in the second direction. In the second state, the two second conductive parts 220 pass through the corresponding clearance openings 330.

[0046] When the housing 100 is inserted into the positioning groove 310, the first housing segment 110 remains within the positioning groove 310. The positioning member 300 has clearance openings 330 on both sides in the second direction corresponding to the positions of the first housing segment 110. The clearance openings 330 penetrate the sidewall of the positioning member 300, and their positions correspond to the positions where the second conductive parts 220 protrude from the first housing segment 110. When the power-taking device 10 is in the first state, the two second conductive parts 220 extend along the first direction and pass through the positioning groove 310 of the positioning member 300 along with the housing 100. When the housing 100 rotates relative to the positioning member 300 in the third direction to the second state, the two second conductive parts 220 rotate accordingly and protrude from the corresponding clearance openings 330 on both sides of the positioning member 300, thereby achieving direct contact and electrical connection with the conductive terminals 23 inside the conductive post 20. Furthermore, the clearance opening 330 effectively prevents the positioning component 300 from interfering with the rotation path of the second conductive part 220, ensuring smooth and unobstructed movement during state switching. Simultaneously, the clearance opening 330 is positioned corresponding to the first shell section 110, resulting in a more compact structural layout. Openings are only made in necessary areas, ensuring the overall structural strength of the positioning component 300.

[0047] In other embodiments, when the abutting part 140 abuts against the stop surface 321, the first shell section 110 passes through the positioning groove 310 and is located outside the positioning member 300. In this way, there is no need to provide the clearance opening 330, and the second conductive part 220 can also rotate freely under the drive of the shell 100. The second conductive part 220 will not interfere with the positioning member 300 and can abut against the conductive terminal 23 in the second state.

[0048] In one implementation, please refer to Figure 1 , Figure 7 and Figure 14 The positioning member 300 has a sliding groove 340 on both sides of the second shell section 120 in the second direction. The sliding groove 340 extends along the first direction and is used to slide and adapt to the edge of the slot of the power take-up slot 22.

[0049] The positioning member 300 has grooves 340 on both sides in the second direction, corresponding to the second shell section 120 of the housing 100. The grooves 340 extend in the first direction and penetrate the lateral area of ​​the positioning member 300. The inner contour of the grooves 340 is adapted to the edge of the slot of the power taking groove 22 on the conductive column 20. Specifically, the width and shape of the grooves 340 match the thickness and shape of the slot edge, so that when the positioning member 300 is installed on the conductive column 20, the edge of the slot of the power taking groove 22 can be embedded in the grooves 340. The grooves 340 and the edge of the slot of the power taking groove 22 form a guide sliding connection, so that the positioning member 300 can be slidably installed or adjusted in position relative to the conductive column 20 in the first direction, supporting the installation and positioning of the power taking device 10 at any position. The groove 340 is provided corresponding to the second shell section 120 of the housing 100, which is located between the first shell section 110 and the third shell section 130. The second shell section 120 has the smallest diameter, which can prevent the second shell section 120 from extending into the groove 340 and interfering with the edge of the power-taking slot 22. When the power-taking device 10 is inserted or moved along the first direction, the positioning member 300 provides reliable guiding support for the movement of the housing 100 through the synergistic effect of the groove 340 and the edge of the slot, ensuring that the power-taking terminal 200 maintains a stable posture during movement and does not twist or tilt, thereby enhancing the stability of the installation of the power-taking device 10.

[0050] In one implementation, please refer to Figure 2 , Figure 6 , Figure 9 and Figure 12 The positioning member 300 has a relief groove 350 on one side of the positioning groove 310 corresponding to the third shell section 130. The third shell section 130 is provided with a marking part 150 protruding from its outer peripheral wall, and at least part of the marking part 150 is located in the relief groove 350.

[0051] The positioning member 300 has a clearance groove 350 formed on one axial side of the positioning groove 310, corresponding to the third shell section 130 of the housing 100. The clearance groove 350 is axially disposed at one end of the positioning member 300. The marking portion 150 is provided on the outer peripheral wall of the third shell section 130 and at least partially protrudes from its surface. When the housing 100 is installed on the positioning member 300 and inserted along the positioning groove 310, the marking portion 150 is at least partially embedded or extends into the clearance groove 350. The cooperation between the clearance groove 350 and the marking portion 150 not only provides axial limiting and circumferential guiding for the insertion of the housing 100, but also indicates the working status or installation direction of the power supply device 10. For example, when the power supply device 10 is in the first state, the user can determine whether the housing 100 is correctly inserted, i.e. whether it is inserted in place, by observing whether the indicator part 150 is located in the relief groove 350; when the housing 100 rotates to the second state, the indicator part 150 rotates synchronously with the third housing section 130, and its position relative to the relief groove 350 changes, forming visual or tactile feedback to prompt the user that the device has switched to the power-on state.

[0052] In other embodiments, the marking portion 150 may also be a visual or tactile identification structure such as a scratch, color mark, or text pattern. The positioning member 300 has a mark corresponding to the marking portion 150 on one axial side of the positioning groove 310 to indicate the installation posture of the housing 100 when it is inserted into the positioning groove 310, and to indicate that the power supply device 10 is in the second state.

[0053] In one implementation, please refer to Figure 2 , Figure 6 , Figure 9 and Figure 15 The housing 100 is provided with a slot 160. The power supply device 10 also includes a rotating handle 400. The rotating handle 400 includes an intersecting mounting part 410 and a gripping part 420. The mounting part 410 is provided with a wire-passing groove 411 that passes through one side of the mounting part 410 away from the gripping part 420. The side of the mounting part 410 away from the gripping part 420 is also provided with a plug-in part 430 that is adapted to be plugged into the slot 160.

[0054] in, Figure 2 The lighter-colored rotating handle 400 indicates that the power supply device 10 is in the first state, while the darker-colored rotating handle 400 indicates that the power supply device 10 is in the second state. Figure 2 The demonstration showed how rotating the handle 400 switches the power supply device 10 from a first state to a second state.

[0055] Specifically, the rotating handle 400 assists the user in rotating the housing 100 to switch the power supply device 10 between a first state and a second state. The rotating handle 400 includes an intersecting mounting portion 410 and a grip portion 420, wherein the grip portion 420 extends from the mounting portion 410 and forms an arc-shaped or rod-shaped structure that is easy for fingers to grip, so as to provide a good fulcrum for force application. When installing or removing the power supply device 10, the user can apply rotational torque through the grip portion 420 to easily complete the rotation of the housing 100, which is especially suitable for occasions where space is limited or a large torque is required. On the side of the mounting portion 410 away from the grip portion 420, there is a plug-in portion 430 that is adapted to the slot 160 on the housing 100. The plug-in portion 430 can be slidably inserted into the slot 160 in the insertion direction, realizing a detachable connection between the rotating handle 400 and the housing 100.

[0056] By detachably connecting the handle 400 to the housing 100, the handle 400 assists the user in easily rotating the housing 100 when rotation is required. When rotation is not needed, the handle 400 can be detached to prevent accidental contact that could cause the housing 100 to rotate and break the circuit. Furthermore, by providing the handle 400, the third housing segment 130 can be housed within the positioning groove 310, preventing excessive exposure of the third housing segment 130, which would otherwise occupy space and potentially increase the risk of accidental contact that could cause the housing 100 to rotate and break the circuit.

[0057] The mounting portion 410 is also provided with a wire guide groove 411 extending through its surface away from the grip portion 420. The wire guide groove 411 extends through at least one side of the mounting portion 410 and is used to accommodate external connection wires led out from the housing 100. When the rotating handle 400 is installed into the housing 100, the external wires can be laid through the wire guide groove 411, preventing the wires from being squeezed, twisted, or tangled during the rotation of the housing 100, thereby improving the safety and reliability of use.

[0058] In other embodiments, the rotating handle 400 can also be fixedly connected to the housing 100; or the rotating handle 400 can be omitted, with the third housing segment 130 protruding outward from the positioning member 300, and force can be applied directly to the third housing segment 130 to rotate it; in addition, the marking part 150 can also serve as the rotating handle 400, and the housing 100 can also be rotated by directly rotating the marking part 150.

[0059] In one implementation, please refer to Figures 9 to 11The housing 100 includes two shell portions 170 joined together. Each shell portion 170 forms two spaced-apart receiving grooves 171. Each receiving groove 171 includes a first groove segment 1711 and a second groove segment 1712. The two first groove segments 1711 extend side by side, and the two second groove segments 1712 extend side by side. A first conductive part 210 is installed in the first groove segment 1711, and a second conductive part 220 is installed in the second groove segment 1712. A second positioning structure is provided between the two shell portions 170.

[0060] The housing 100 is formed by the joining of two interlocking housing parts 170. The two housing parts 170 are assembled and fixed along the interlocking surface by means of snaps, fasteners, or adhesives to form a complete housing 100 structure. Each housing part 170 is provided with two spaced-apart receiving slots 171. Two power-taking terminals 200 are disposed in corresponding receiving slots 171 and are spaced apart to prevent the two power-taking terminals 200 from contacting and causing a short circuit. The receiving slots 171 include a first slot segment 1711 and a second slot segment 1712. The two first slot segments 1711 are parallel to each other and spaced apart, and are used to install the first conductive part 210 of the power-taking terminal 200; the two second slot segments 1712 extend outward away from each other, and are used to install the second conductive part 220 of the power-taking terminal 200.

[0061] After the two shell portions 170 are joined and fixed, the first groove segments 1711 on both shell portions 170 together form a first mounting cavity for fixing the first conductive part 210, ensuring the stable installation of the first conductive part 210. Similarly, the second groove segments 1712 on both sides are joined to form a second mounting cavity for the second conductive part 220, ensuring the stable installation of the second conductive part 220. The split design of the shell 100 allows the power terminal 200 to be accurately embedded into the corresponding groove segment during the assembly of the shell 100. At the same time, the bent configuration of the receiving groove 171 matches the L-shaped structure of the power terminal 200, effectively preventing displacement or rotation during use.

[0062] A second positioning structure is provided between the two housing parts 170. This second positioning structure plays a role in pre-positioning and alignment during the splicing of the housing parts 170, ensuring that the two housing parts 170 are accurately positioned and do not shift during assembly, thereby ensuring the continuity of the internal receiving groove 171 and the installation accuracy of the power supply terminal 200. In addition, this structure can also enhance the connection strength between the two housing parts 170, prevent the housing 100 from cracking or loosening due to vibration or external force, and improve the sealing and reliability of the overall structure.

[0063] Furthermore, the second positioning structure includes a positioning groove 173 and a positioning protrusion 174, used to achieve rapid alignment and precise fit during the splicing of the two shell parts 170. Each shell part 170 is provided with at least one positioning groove 173 and at least one positioning protrusion 174, and the positioning groove 173 and the positioning protrusion 174 are respectively located on opposite sides or symmetrical areas of the shell part 170. When the two shell parts 170 are aligned along the splicing direction, the positioning protrusion 174 of one shell part 170 is inserted into the positioning groove 173 of the other shell part 170 to form a plug-in fit, and vice versa, thereby achieving bidirectional positioning.

[0064] The positioning groove 173 can be a blind hole, through hole, or U-shaped groove structure, and is set on the inner wall or splicing surface of the shell 170; the positioning protrusion 174 is a columnar, conical, or rib-like structure that matches its shape, and can be elastically or interference-fitted into the positioning groove 173. This not only improves the alignment accuracy during the splicing process and prevents misalignment or skew, but also enhances the overall structural stability and torsional resistance of the shell 100. In addition, this symmetrical arrangement allows the two shells 170 to be formed using the same mold (i.e., mirror images or identical to each other), which helps to reduce mold development costs and improve production efficiency and component versatility.

[0065] In one implementation, please refer to Figure 10 and Figure 11 The bottom of the first groove segment 1711 is provided with a limiting protrusion 172, and the first conductive part 210 is provided with a limiting notch 211 corresponding to the limiting protrusion 172. The limiting protrusion 172 is locked in the limiting notch 211.

[0066] The bottom of the first segment 1711 of the receiving groove 171 is provided with at least one limiting protrusion 172, and the outer surface of the first conductive part 210 is provided with a corresponding limiting notch 211 that matches the limiting protrusion 172. When the first conductive part 210 is inserted into the first segment 1711, the limiting protrusion 172 is elastically or interference-fitted into the limiting notch 211. The limiting protrusion 172 protrudes inward from the bottom of the first segment 1711 and can be square, cylindrical, hemispherical, or conical. The limiting notch 211 is formed on the first conductive part 210, and its shape and size are adapted to the limiting protrusion 172. During assembly, the first conductive part 210 is inserted into the first groove 1711, and the limiting protrusion 172 is squeezed and undergoes slight deformation and is embedded in the limiting notch 211. This can effectively prevent the first conductive part 210 from moving or rotating during use, ensuring the stability of its connection with the external power supply, and avoiding loosening of the contact due to vibration or thermal expansion and contraction.

[0067] In one implementation, please refer to Figure 10 and Figure 11The shell portion 170 also has a clearance groove (not shown in the figure), which is located at one end of the second groove segment 1712 that connects to the first groove segment 1711 and is connected to the second groove segment 1712. The clearance groove extends along the radial or bending transition area of ​​the shell 100, and its spatial dimension is larger than the cross-sectional dimension of the second conductive part 220, so as to provide elastic deformation space for the second conductive part 220.

[0068] When the power-generating device 10 switches from the first state to the second state, the housing 100 drives the second conductive part 220 to rotate, changing its extension from the first direction to the second direction, and it comes into contact with the conductive terminal 23 inside the conductive post 20. During the contact process, the conductive terminal 23 applies pressure to the second conductive part 220, causing the second conductive part 220 to undergo inward elastic deformation. At this time, part of the second conductive part 220 is compressed inward and extends into the relief groove, thereby avoiding plastic deformation of the material or structural damage due to excessive force.

[0069] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
